Sorption of Aspirin from Aqueous Solutions using Rice Husk as Low Cost Sorbent
Volume 8 | Issue 1 | Pages: 1-5 | PDF | HTML
Abstract: The Rice Husk (RH) was used as low cost sorbent for the removal of aspirin by sorption from aqueous solution. The RH was characterized by using the point of zero charge (pHpzc), Boehm titration and Fourier transform infrared spectroscopy (FTIR). Batch sorption experiments are intended to identify the adsorption isotherms of aspirin on the RH. The experimental data were fitted to the Langmuir and Freundlich isotherms. The Sum of the Squares of the Errors (SSE) and the correlation coefficient R2 between the calculated and the experimental data by nonlinear regressive analysis were used. The Langmuir model better described the isotherm data with the maximum Langmuir monolayer adsorption capacity was 47.03 mg g-1 at pH 2. As a conclusion, RH could be one of the low cost and environmentally friendly sorbent.
Keywords: Aspirin, Rice Husk, low cost sorbent, isotherms.
Abstract:
The turnover among academicians is established in
Nigeria by Nigeria Institute of Management, citing turnover rates in tertiary
institutions ranging from 11% to 18.3%. Therefore, this paper provides a review
of HRM, workplace bullying and turnover intention. It is argued that both HRM
and workplace bullying are two important conditions that affect employee’s
turnover intention. Drawing on social exchange theory, this paper suggests that
there is a significant relationship between HRM, workplace bullying and turnover
intention. The study used 45 research papers such as (EBSCOhost, Emerald, JSTOR,
PsycINFO, SAGE Premier, ScienceDirect, Scopus, SpringerLink, Springer Protocols,
and Taylor & Francis) to unearth out appropriate data for the study. The
researchers extracted articles that are as relevant as possible. The research
conducted from April to September 2018 and supported by peer-reviewed research
papers published in English. This paper proposes work engagement could be a
potential mediator between HRM and turnover intention. In addition, this paper
also proposes if work engagement mediates the relationship between workplace
bullying and turnover intention. This paper conceptualizes HRM into five main
dimensions, namely career development, performance appraisal, training and
development, reward and recognition and recruitment and selection. Suggestions
and implications for future study on HRM, workplace bullying, and turnover
intention are also suggested

Abstract:
Today, the exploding population, rising costs of living, and limited living
spaces have led to various social problems for urban residents. World
governments have been gradually moving towards promotion of urban wellbeing
where urban centres must be ecosystems that promote societal health and
wellbeing as well as conducive for improving its residents' quality of life
(21). Malaysia is of no exception; despite the various initiatives by the
Government, recent years have seen an increase in residential crime and this has
adverse impacts on urban wellbeing. This paper discusses how crime affects urban
wellbeing and how the problem may be contained. Semi-structured interviews
conducted with residents in crime-prone areas in Malaysia have found that
growing criminal activity might lead to urban flight or depopulation of
residential estates. This runs counter to urban wellbeing as it increases the
stress levels of families by destabilising them. The interview also revealed
that these problems may be curbed by increasing the safety through various
spatial management practices as well as knowledge sharing and participation by
residents in community events. This study provides recommendations to federal
and local authorities in spatial policies as well as for housing developers in
designing future housing projects.

Abstract:
The workers’ compensation firm offers reasonable compensation to its beneficiary
members when it comes to occupational disease. While common occupational-related
injuries are visually justifiable, many illnesses influenced by biological
hazard are difficult to predict as it takes years for the disease to develop,
depending on the individual immune system. The occupational disease that
consists of physical injury and microbial infection were rising in the past
decades. This paper discoursed a winding microbial infection from direct contact
and prolonged condition, which both are originated from physical injuries. In
principle, the complexity to extenuate microbial pathogenicity usually hamper
compensation claims; as it faced various challenges and condition to meet its
requirement. We included several legal opinions that support compensation
benefits, in hope to leverage a hopeful transition of compensation rights of
trained workers such as paramedic, researcher, frontlines, customer services,
and other biological-risk industry workforces.

Abstract: Drawing upon resource-based theory, as well as contingency theory, this study examined the role of competitive intensity in moderating the relationships between entrepreneurial orientation, total quality management, and SME performance. Using a stratified random sampling, 714 self-administered questionnaires were distributed to owner‐managers of SMEs operating in Kano and Kaduna in the north-west geopolitical zone of Nigeria. Of the 714 questionnaires distributed, 440 unusable questionnaires with 62 percent responses were returned and further analysed. The hypotheses were tested using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results supported the hypothesised main effects of entrepreneurial orientation, and total quality management, on SME performance. Also, the competitive intensity was found to moderate the relationships between entrepreneurial orientation and SME performance. On the contrary, no significant interaction effect was found between total quality management and competitive intensity. The theoretical contribution of the present study lies in its use of competitive intensity as a moderator of the relationships between entrepreneurial orientation, total quality management, and SME performance.

Abstract: Literature on asymmetric dividend smoothing mostly focused on establishing the existence of the behavior within firms without accounting for firm characteristic variables that influence dividend smoothing. Given that firms that smooth dividend payment more tend to have low growth potentials and likely to be affected by severe agency conflict; therefore, asymmetric smoothing behavior is expected to vary according to growth potentials. In this regards, the study aims at examining the determinants of asymmetric dividend smoothing behavior after accounting for whether the behavior exists in firms with high/low growth potentials. The paper used data obtained from a sample of 9 out of 16 Industrial Goods firms listed on the Nigerian Stock Exchange for the period of 11 years - 2006-2016. The model of the study was estimated using Fixed Effect Model. The findings reveal that Industrial goods firms in Nigeria smooth dividend payment and have asymmetric dividend smoothing behavior. The adjustment rate is not only asymmetric below and above their Target Pay Out Ratio (TPR) but also asymmetric below TPR for both High and Low growth potentials. However, the behavior only exists above TPR when the firms have high growth potentials. The paper concludes that firms with high growth potentials have slower adjustment rates than the ones with low growth potentials when they are below their TPR.

Abstract: This study integrates equity theory and social exchange theory to explore the impact of internal branding practices on employees’ brand citizenship behaviour (BCB) through the mechanism of employee-brand fit. Self-administered questionnaires were randomly distributed to 377 employees in Nigeria’s telecommunication industry. However, only 254 were found to be useful in the present study giving the response rate of 68%. The empirical results show that brand training and brand leadership have significant impact on employees’ BCB. In the same vein, significant relationship was revealed between brand leadership and employee-brand fit, but insignificant impact was established between brand training and brand fit. Moreover, it was discovered that employee-brand fit has significant impact on employees’ BCB. Employee-brand fit was found to mediate the relationship between brand leadership and employees’ BCB while it does not mediate the relationship between brand training and employees’ BCB. Practically, our study has provided the management of companies in the telecommunication industry with the importance of internal branding for employees’ outcome such as brand fit and BCB. Therefore, the management of companies in the telecommunication industry should prioritise, promote, and improve their internal branding management. Implications and directions for future study were discussed.

Abstract: Heavy metals are not dissoluble in the environment and can be dangerous for many species. So, removal of heavy metals from the water and wastewater is an important process. In this research, eucalyptus sawdust was prepared and employed for removal of Cadmium ions from aqueous solution. For this purpose, several parameters such as pH of aqueous solution, adsorbent dosage, contact time, initial concentration of cadmium ion and mixing rate were studied. The results showed that the best conditions for the removal of Cd2+ were obtained at temperature of 30°C, mixing rate of 200 rpm, pH of 8, adsorbent dosage of 5 g/l, and initial concentration of cadmium of 200 ppm which the removal efficiency was obtained 89.3 %. In order to study the kinetics of adsorbent, the pseudo-first order and pseudo-second order kinetic models and intra-particle diffusion model were applied. According to the correlation coefficient (R2), pseudo-second order kinetic model showed better correlation for kinetic behavior of the adsorbent. Furthermore, to study the equilibrium behavior of adsorbent, Langmuir and Freundlich models used and results showed that the Langmuir isotherm model had better matching with experimental data. So, this adsorbent can be used as natural and cheap adsorbent to remove Cd2+ ions from aqueous solutions.

Abstract:
As one of emerging and developing
country, Malaysia is under pressure to reduce energy consumption and carbon
emissions. Companies especially those with high hazardous wastes production need
to ensure that their wastes are improperly treated, stored, transported or
disposed off or managed in order to minimize it impact to environment. In view
of this, Green Supply Chain Management (GSCM) is important in influencing the
total environment impact of any companies involved in supply chain activities as
well as contribute to sustainability performance enhancement. This study aims to
examine the employee’s insight from Malaysia Chemical Related Industry on their
firm’s green supply chain management practices and environmental performance.
Based on the theoretical framework of green supply chain management practices,
an empirical study of the green supply chain management practices and
environmental performance was conducted. Out of the five variables of green
supply chain management practices, only the legislation and regulation have
positive significant relationship with environmental performance. This result
shows that most employees consider that their firm’s environmental performance
will be improve by complying with the legislation and regulation rather than
proactively develop green supply management practices.

Abstract: The article analyzes the proposed index "fixed assets and investments" in the aspect of the potential of reindustrialization processes in the economic systems of the Federal districts of the Russian Federation, which allows to ensure the comparability of the used absolute and relative statistical indicators. This work is the result of a study of the theory and practice of reindustrialization aimed at improving the efficiency-cy and competitiveness of the Russian economy in the face of negative external influences. The main theoretical approaches to the study of the concept of reindustrialization and its potential, its role and importance in ensuring the economic sovereignty of the country and economic growth are considered. The reindustrialization potential was estimated on the basis of 14 indicators and normalized indices calculated on their basis. The study of the dynamics of these indicators for 2005-2017 indicates the presence of certain positive changes in this area, but the structure of fixed assets and the nature of investment processes in the Russian Federation do not allow us to conclude that the predominance of the reindustrialization vector in this sphere of social production. At the same time, the economic policy currently being implemented in the Russian Federation does not promote reindustrialization, namely the renewal of fixed assets on a qualitatively new, modernizing basis. Based on the analysis of the integral index "fixed assets and investments" it can be concluded that the distribution of Russian Federal districts this index shows a certain stability, growth, analyzed the integral index was noted in all Russian Federal districts, except Urals FD, which indicates a certain improvement in the status and dynamics of basic assets and investments in the Russian economy. The approved methodology can be used to assess the potential of reindustrialization in individual regions, the totality of all Russian regions, as well as indicative planning of regional and Federal socio-economic development.

Volume 8 | Issue 1 | Pages: 156-161 | PDF | HTML
Abstract: The article reviewed a method for assessing the influence of a probabilistic load on the amount of energy loss in an engine-and-transmission unit (ETU) of a mobile aggregate. The method is based on the usage of a random processes theory. The random process is a sum of harmonic components with a random initial phase and constant amplitude. The image of the random process corresponds to an arcsine distribution, in which the normal distribution law is approximated by an arc sine function. A peculiarity is that the approach allows you to obtain characteristics that reflect the dependence of the energy performance of the engine-and-transmission installation on the frequency of oscillations of the rotational speed of the crankshaft of an internal combustion engine. The frequency characteristics of the mathematical expectation of the effective power of the internal combustion engine, dissipative losses in the dynamic systems of the internal combustion engine and transmission are obtained as a result of all calculations. We propose a generalized criterion to assess the energy efficiency of a mobile unit under the influence of a probabilistic load.

Abstract: The aim of the study was to evaluate morphological alterations in the parameters of the local cellular immunity of the oral mucosa (LCI OM) in patients with diabetes mellitus (DM) and removable denture based on the analysis of the biopsic material. The study included 130 patients aged 40 to 85 years old that were split into control (n=32) and test groups. The patients were installed partial laminar denture and complete removable denture: Test group I – patients with DM (n=70); Test group II – patients with DM (n=28) that received immune-stimulating drug. The oral cavities were examined with clinical methods. The bioptates obtained from the oral mucosa were studied with morphological immunohistochemical methods using antibodies to CD68, CD204, CD163, CD4, CD8, CD11/303, and Ki-67. The obtained data were statistically processed. The examination was performed in 6 and 12 months after the installation of the denture. The parameters of LCI OM in patients with DM significantly differed from the parameters in healthy patients. It was established that the installation of removable acrylic denture led to significant changes in the parameters of LCI OM. Clinical manifestations of the periodontal tissues inflammation directly depended on the duration of the application of denture and the composition of the inflammatory cells. The application of immune-stimulating drugs in patients with DM with removable denture led to qualitative and quantitative changes in the local cellular immunity that differed from similar changes in patients that did not receive immune stimulators and correlated with the intensity of clinical manifestations of periodontium tissues diseases.

Abstract: In his first year in office, President Donald Trump broke strongly with some long-standing customs in US international strategy. Shockingly, the consideration the organization is paying to Southeast Asia has been one territory of relative congruity. Prior to the Obama organization, US governments flopped in key minutes to reliably concentrate on the area. Previous president Bill Clinton's clinical and disengaged reaction to the Asian monetary emergency in 1997–98 undermined the United States' remaining among Southeast Asian nations hit hard by the emergency. Previous secretary of state Condoleezza Rice's choice to avoid two ASEAN Regional Forum gatherings in three years underscored the George W Bush organization's distraction with the Middle East.

Abstract: Trade protection is the intentional endeavor to constrain imports or advance fares by setting up boundaries to trade. Notwithstanding the contentions with the expectation of free trade and expanding exchange receptiveness, protectionism is still broadly drilled. Protectionism is the monetary strategy of confining imports from different nations through strategies, for example, levies on imported products, import portions, and an assortment of other government guidelines. Advocates guarantee that protectionist arrangements shield the makers, organizations, and laborers of the import-contending area in the nation from outside contenders. Be that as it may, they additionally lessen exchange and unfavorably influence purchasers as a rule (by raising the expense of imported merchandise), and damage the makers and laborers in fare divisions, both in the nation actualizing protectionist approaches and in the nations ensured against.

Abstract: This article discusses the problem of technological support for the professional development of specialists in the field of physical education and sports, which is especially acute in modern society, where social requirements for them are becoming stricter and adamant, and the conditions for the manifestation of pedagogical creativity are significantly reduced due to the introduction of multilateral normative regulation of the teacher and trainer. In these conditions it is difficult for a specialist to choose a vector and methods for realizing his own potential in his professional activity. Physical education teachers working in the framework of institutions of additional education for children are considered in the article as the illustration of this problem. The goal is to analyze the content-technological and organizational support for the professional development of a physical education teacher in an educational organization to identify a set of pedagogical conditions that increase the efficiency of this process. The article presents the results of an author's study of the dynamics of professional development of teachers in the field of physical education using meta-educational design technology. The stages and mechanisms of this process are described. The materials can be used to organize the formation of professional competence and professional development of secondary vocational, higher and additional professional education in the field of physical education and sports, as well as adaptive physical education and adaptive sports.

Abstract: In recent years, interest in the problems associated with the social adaptation of students to the conditions of university is growing in the scientific literature. The influence of some psychological factors on the success of adaptation of first-year students has been investigated. The study aims at presenting the comprehensive analysis of psychological factors influenced on the adaptability of first-year students to the conditions of university. The study was conducted in the South Ural State Humanitarian and Pedagogical University. 142 first-year students took part in it. The following methods were used: progress analysis, sociometry, the questionnaire “Adaptation of university students”, the self-assessment of emotional states, the questionnaire of temperament structure, the sixteen personality factor questionnaire by R. Cattell, and the questionnaire “Adaptive behavior strategies”. The main method of processing the results of the study is the multiple regression analysis. The regression model accounts for the different rates of adaptability from 41% to 59% of the variance. As a result of the study, the psychological factors that affect virtually all the indicators of adaptability have been identified. These include the level of development of conceptual thinking, the formation of educational and cognitive motives, attitudes toward parents, satisfaction with relationships with teachers. In addition, factors that influence the success of adaptation to different spheres of life of students are revealed. To adapt to the educational activity, introversion, sensitivity, high intelligence, skills of educational activity, motives of creative self-realization are more important. Extraversion, plasticity of the nervous system, expressiveness, social courage, calmness, and communicative motives are more important for adaptation to the study group. The adaptability to the internal criterion (subjective well-being) is most affected by satisfaction with living conditions.

Volume 8 | Issue 1 | Pages: 257-265 | PDF | HTML
Abstract: The paper analyzes the problems of local-group behavior of business agents in the institutional environment of the region. As a research hypothesis, it is assumed that local groups of economic agents often form independent attitudes beyond the general trends of institutional nature, reacting to them in the mode of reflection. The study was carried out using the methods of historical, logical, structural analysis, system approach, organizational and mathematical models. The article considers the existing approaches to the concept of institutional environments of business, institutions, their functions and limitations, and establishes a fundamental difference between the external and institutional environments. Various issues related to the quality of institutions and factors of their impact on the business community of the region are discussed, in particular, the influence of these factors on the manifestations of competition and the shadow economy is noted. The main part of the study is devoted to the formation of local business communities, their interaction in the existing institutional conditions and constraints, as well as their identification in various systems of indicators. It is proposed to consider the individual groups of business agents localized on certain characteristics and criteria as “business populations”, the behavior of which is formed both at individual and group levels. At the same time, the problem of similarity of agents belonging to certain local groups is required to address by a model approach based on the use of different metrics and population classifications. The proposed approach is illustrated by a virtual example. As a result of creating an institutional graph, a second-level model for horizontal network cooperation for local groups of business agents can be developed in the future. The authors come to the reasoned opinion that local-group entrepreneurial behavior has independent categorical features, spiral character of development in the institutional environment and does not copy both the general trend of development of the whole community and the individual behavior of business agents. However, the latter has a certain influence on the formation of local groups’ behavior in the current conditions of institutional constraints.

Abstract: Education, as the most important kind of social activity, changes the cultural image and consciousness of a person. This is the way the political function of education is realized. Education is designed to form a stable relationship of the individual with the society and is, therefore, the most important means of communication. In this article, the authors analyzethe political aspects of education in general and civil education, in particular. The authors focus their attention on the potential of civil education for the formation of self-consciousness of the 21st century in the modern Russia. The product of this self-consciousness is a new identity that is viewed as a result of the construction of social values and their interiorization in the individual consciousness. In the analysis of the political aspects of education in contemporary Russia, the following conclusions are drawn. The fundamental basis of civil education is statehood. Statehood is understood by the authors as a functional dependence of public consciousness on existing political institutions and norms, as well as the influence of the consciousness on institutional changes. The main targets of civil education are: loyalty, civic consciousness, patriotism. Loyalty involves the conscious recognition of the common rules by the individual. Civic consciousness is a specific way of communication between the individual and authorities, society and the state, in which all participants of the political process are institutionally equal. Patriotism implies meaningful behavior, which is based on the continuity of culture and the preservation of the historical tradition, personal responsibility for the fate of the fatherland. The article is intended to give a broad audience of foreign readers specific ideas about the problems of civil education in modern Russia, its tasks and prospects.

Volume 8 | Issue 1 | Pages: 272-283 | PDF | HTML
Abstract: Poly propylene is one of the famous polymers with great application. In this study, CFD model on dynamics of the fluidized bed polyethylene production process has been investigated. A detailed CFD model for sticky poly propylene fluidized bed was formulated in this work. As a result, detailed information on the PSD and hydrodynamic fields of the gas and solid phases can be obtained from the simulations. Defluidization due to particle aggregation also can be simulated. For modeling plant-scale poly propylene reactors, a chemical look-up table should be used to solve efficiently the solid species equations. In order to address all the issues in FB polymerization, models for simplified polymerization kinetics, polydisperse multiphase flow, and mass and heat transfer between the gas and solid particles are combined together. As a result, physically aggregation because of a tactic polypropylene is more important than other aggregation reasons. Finally, as mentioned earlier, after DQMOM is applied to the multi-fluid CFD model, new terms accounting for the effect of aggregation and breakage need to be added on the right-hand sides of the solid-phase momentum, energy, and species equations.

Abstract: Green synthesis of nanoparticles has received extensive attention in the field of nanomedicine as a simple, environment-friendly and cost-effective alternative in comparison with other physical and chemical methods. Silver nanoparticles (AgNPs) are playing an important role in the field of nanomedicine and nanotechnology due to their unique and controllable characteristics. In this research, a biosynthesis approach was used for synthesis of silver nanoparticles (AgNPs). Biosynthesis was carried out by Stachys lavandulifolia Vahl. extract as green reducing agent for conversion of Ag+ to Ag0. The first visible sign of the synthesis of AgNPs was the change in color of solution from yellowish to reddish brown. The preparation of AgNPs was performed using several techniques such as, UV-vis spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and dynamic light scattering (DLS). Finally, synthesized AgNPs were evaluated for their antimicrobial activity against four standard bacterial strains using microbroth dilution method. Results of TEM image showed spherical nanoparticles with high crystalline and monodispersity which is very important in medicinal applications. Additionally, DLS analysis demonstrated the ultra-fine size of AgNPs with average size of 164.8 nm. FTIR indicated the role of different functional groups (carboxyl, amine and hydroxyl) in the formation of Silver nanoparticles. A negative zeta potential value of -17.3 mV determined the stability of the silver nanoparticles. AgNPs showed good antimicrobial activity against both gram-positive and gram-negative bacteria, with MICs of 4 to 16 μg mL. In conclusion, the results imply that the synthesized nanoparticles using green nanotechnology could be an ideal strategy to combat multi-drug-resistant pathogenic bacteria.

Volume 8 | Issue 1 | Pages: 291-298 | PDF | HTML
Abstract: The relation of transport and energy industry is not always taken into account in the legal regulation of emerging social relations. Unfortunately, there is currently no systematic legal regulation of transport and energy industry relations, as well as no scientific research on this issue. It is mainly due to the fact that both bachelor's and master's programs study two different disciplines "Transport law" and "Energy law". Or worse, the educational program does not provide for such disciplines. Agreements on joint activities are one of those unifying bases that can be form integration of regulatory material in the studied fields. The research focuses on forming a scientific image of joint activities agreements used in the transport and energy industries. Methods The research involved system approach, comparison, description, and interpretation, as well as theoretical methods of formal and dialectical types of logic. The specific scientific methods included the comparative legal method and interpretation of legal norms, and legal modeling. Results This work outlines the range of agreements on joint activities in the transport and energy sectors and make up a single integrative system. The study reveals the common features of these agreements that give them the proper legal qualification. The legal nature of the code-sharing agreement is defined, its independence is proved. The work involved the separation of this agreement from other types of civil law agreements. This paper is written in a separate co-authorship. Introduction and the first part deal with the common characteristics of the agreements on joint activities in energy and transport industries and are written by S. Yu. Morozov. The second part on the interaction of carriers under the terms of the code-sharing agreement is written by Fedotova D. S.

Abstract: The recent global turn on to more effective and systematic action to reduce pollution in the context of greenhouse gases (GHGs) (primarily considered to be responsible for global warming and its related adverse effects) has led to severe discussions among various institutions, organizations and scholars from developing and developed nations in respect to the potential impacts of these efforts. This research offers a review of research on the impact of Renewable Energy used and Pollutant Emissions on Sub-Saharan African countries' economic growth. Besides, the researchers reviewed 50 articles published between 2015 and 2019 in Scopus Journals. The papers are carefully evaluated based on the comprehensive recurring variables like the theoretical point of view, the economic conditions, and the analytical perspective. Nevertheless, the empirical study showed that Renewable Energy Use, Pollutant Emissions, recorded a significant impact on economic growth. Consequently, the findings of the reviewed studies have suggested an economic growth model that can direct sub-Saharan African nations to understand better and improve the Renewable Energy Use and Pollutant Emissions at their reach regarding viable economic development provisions. A proposed model is recommended for the analysis that is best suited for economic growth.

Abstract: The aim of this study is to assess the competitive adsorption of two pharmaceutical products, phenobarbital and ibuprofen using powdered activated carbon (PAC) F400. The adsorption tests were carried out in batch experiments. The kinetic adsorption results showed that the PAC adsorbs good lipophilic ibuprofen with an adsorption capacity reaching 101.46 mg g–1 against 63.46 mg g–1 of phenobarbital. The adsorption capacity was negatively influenced by the presence of both adsorbates compared to their individual adsorption onto PAC. logkow, pKa values, and molecular weights played a crucial role on the adsorption capacities of the target compounds onto PAC. The results obtained show that the adsorption of both pharmaceuticals follows a pseudo-second order model through a complex process including connecting layer and intra-particle diffusion in micropores. According to the results, the isotherm models of Langmuir, Freundlich, and Temkin fit well the experimental data for each selected pharmaceuticals. The bT values show that the competitive adsorption process of each pharmaceutical is a physisorption without formation of links.

Abstract: In the current study, planning for optimal utilization of groundwater resources is described. Kahorestan plain in Hormozgan province was the study zone. Since the main problem of the plain is high salinity of groundwater, chloride concentration was examined as an indicator of salt and also water quality degradations. This decision was made due to its high solubility, poor absorption, and stability of the compounds in the groundwater. A quality model was developed using software coding of visual mudflow to identify the problem. The collected chloride data of Kahorestan water wells were processed as an input in MT3D software from 2007 to 2011. Longitudinal and transverse diffusion coefficients were calibrated and the distribution of contaminants in the Kahorestan aquifer was analyzed. The mathematical model was developed to predict and simulate groundwater quality by October-2014. According to a developed qualitative model, the average concentration of chloride in groundwater was increased due to the need for more withdraw about a 5% increase in some parts of the northwest plains. Besides, the plain faces with a growth rate of chloride concentration about 3% compared to the initial situation in October-2011. Furthermore, to reduce the salinity, management schemes and plans were presented to reform water-use patterns, especially in the agricultural sectors.

Abstract: Use of satellite images to detect hydrothermal alteration zones can be helpful for efficient mineral explorations. Remote Sensing (RS) techniques make it possible to save cost and time for accurate primary explorations. The purpose of this research is to use the image processing techniques to detect porphyry copper minerals through the index of hydrothermal alteration mapping in Chahr Gonbad, Sirjan, Iran. We have obtained Landsat imagery data of Enhanced Thematic Mapper (ETM) and Operational Land Imager (OLI) for the analysis. For enhancement and detection of the alteration zones, we have applied useful RS methods including image difference and band color composite, band ratios, Principal Component Analysis (PCA), Crosta, and Matched Filtered. The results discovered argillite and propylitic alteration zones through iron-oxide and hydroxyl minerals in the study area. The image processing has revealed that the detected alteration minerals have relation with mineralization of porphyry copper. The zones are mainly developed in a northwest-southeast orientation and mostly concentrated in center and south of the Chahr Gonbad.

Abstract: This paper explored the challenges present in the offshore medical emergency response (MER) system from the perspective of offshore medics by reflecting on their experiences in handling delays in emergency medical evacuation cases. We conducted qualitative interviews using the critical incident technique method. The participants recruited using the purposive sampling method comprise of 8 experienced offshore medics working on various types of oil and gas offshore facilities across the Malaysian Offshore. Data analysis was performed using qualitative content analysis. The in-depth individual interviews have resulted in the identification of 114 critical incidents for analysis. Seven themes emerged on MER system challenges including communication, decision making, facility layout, logistics problems, offshore medic responds, SOP and protocols as well as weather conditions. Decision-making was found to be one of the major challenges. The results suggest that the MER system needs to be revised in its current practice and we have proposed revisions to the industrial guidelines on response time tiers. This study has added a new understanding on the challenges found in the MER system from a different perspective.

Volume 8 | Issue 1 | Pages: 374-381 | PDF | HTML
Abstract: Generally, as drought, inadequate rainfall means; the concept of drought is not just about reducing rainfall. When years of humidity in an area are lower than average, this is caused by the disruption of our balance between rainfall and evapotranspiration. The reason for droughts is not always the same. It is also difficult to estimate the start and end of the drought. Drought, a mysterious pest, has emerged mysteriously, showing its effects slowly and it goes on for a long time. In this study, drought analysis of the Yesilirmak River basin area in the Black Sea region between 1970 and 2014 was performed. Initially to conduct research, meteorological stations in the basin area that had been collecting data for a long time were investigated, required hydro meteorological data have been obtained from the Meteorological Office which is calculated accurately based on meteorological drought values. Rainfall and drought performance have been investigated with different indices. In this study, monthly precipitation data for inland basin stations, with 7 different meteorological drought indices (PN, DI, RAI, ZSI, CZI, MCZI and SPI) on 7 time scales 1,3,6,12,24,36 and 48 are used and so there is a comparison between drought indices and time periods and all droughts were also recorded during the study period. Finally, the 12-month SPI index was selected as the best index and time scale for the basin and the drought maps for the area were extracted using the SPI index results.

Abstract: This paper investigated the causal relationships among environmental degradation, energy consumption, energy price, energy intensity, and economic growth using simultaneous-equations models with panel data of OPEC African countries from 1970 through 2018. The study used second-generation techniques to analyse the stationarity and co-integration relationship among the variables. The empirical results of the research showed that there exists a bidirectional causal relationship between energy consumption and economic growth; and energy prices and economic growth; and environmental degradation and economic growth. Moreover, the result revealed a unidirectional causal relationship running from economic growth to energy intensity. Nevertheless, the findings show a unidirectional causality from energy consumption to energy intensity with no effect of feedback, and there exists a bidirectional causal relationship between energy prices and energy intensity; between environmental degradation and energy intensity; and between environmental degradation and energy prices for all OPEC African countries. The study recommended that energy policies should identify the dissimilarities in the causal linkages between economic growth and energy consumption to retain sustainable energy consumption in OPEC African countries.

Abstract: In bridge designing the live loads plays an important role. Most of the developed countries have their own code for highway bridges design specification while the other countries adopt certain renowned design codes but with certain additions to meet their demands. In Pakistan, two different codes are followed for designing of bridges i-e American Association of State Highway and Transportation Officials and West Pakistan Code of Practice for Highway Bridge. But both of these codes live load models are not representative of the present truck traffic situation in Pakistan. For this research study, the MULLA MANSOOR weighing station was selected which is located on Grand Trunk road of Pakistan. This paper aim is to study the statistical analysis of weigh in motion data and comparative analysis of short to medium span length typical I girder bridges i-e 10m to 50m with 5m increment. This will help in comparing the live load effects with the actual truck traffic data for proposing a new live load model in Pakistan. The method applied for achieving the objectives is based on Line load analysis i-e Load Resistance Factor Design Equations spreadsheet for bridges design in Pakistan for developing the Live load model and modification in codes.

Volume 8 | Issue 1 | Pages: 429-436 | PDF | HTML
Abstract: Porous concrete has been used in sidewalks and surface pavements since the last decade for management of urban runoffs. Porous concrete is considered valuable for its hydraulic conductivity, adsorption capacity for pollutants, reduction of turbidity and contaminants, especially heavy metals. The present research examines the effect of adding minerals such as zeolite (Z), perlite (Pe), pumice (Pu) and LECA (L), which are able to adsorb pollutants, at different percentages (0, 5,10 and 15%) and fine-grains (0, 10 and 20%) to porous concrete blocks to evaluate its mechanical characteristics such as compressive strength, permeability and porosity and the ability to improve runoff quality (EC, TDS, NaCl, COD, BOD and turbidity). Results showed that adding fine-grains improved runoff quality and enhanced compressive strength, but led to lower permeability and porosity. All adsorbents enhanced the quality of runoff and the increase was prominent at higher percentages of additives. Porous concrete had little effect on reducing EC, TDS and NaCl contents. The best results belonged to samples containing zeolite and LECA. The L15-0, Z15-10 and L15-20 treatments (containing 0, 10 and 20% fine-grains and 15% adsorbent) had the highest pollution reduction and improved the TSS (75.8, 79.1 and 84.6%), COD (87.1, 82.6 and 89.3%) and BOD (88.1, 87.3 and 90.7%).

Abstract: Nowadays, utilization of new and sustainable techniques for the synthesis of INPs are increasing significantly. Common nettle (Urtica dioica) or stinging nettle is an herbaceous perennial flowering plant with a significant reduction potential. Leaf extract of this plant can reduce iron ions to zero-valent INPs. Like all chemical and biochemical reactions, reaction conditions have an immense effect on the process. In this experiment, impacts of different process parameters such as FeCl3 concentration, leaf extract quantity, reaction temperature, and reaction time on the biosynthesis of INPs were evaluated. FeCl3 concentration, quantity of the leaf extract, and reaction temperature were identified as effective factors. But, reaction time has not any significant impact. INPs were characterized by transmission electron microscope (TEM) Fourier transform infrared (FTIR) spectroscopy, and X-ray diffractometer. Particles were spherical and oval in shape and were measured to be 21–71 nm with mean particle size of 46 nm. TEM illustrated that the zero-valent iron (ZVI) nanoparticles had mostly a spherical shape with 46 nm of mean diameter. The particles tend to form irregular clusters with phytochemicals from leaf extract and form macrostructures in the range of 117–605 nm. Prepared nanostructures are a promising catalyst in Fenton reactions and can degrade Methyl orange dye with about 70 percent efficiency in 5 h.

Volume 8 | Issue 1 | Pages: 448-454 | PDF | HTML
Abstract: The study assessed the growth and nutrient uptake capacity of Hymenachne acutigluma (Steud.) Gillilland by cultivating plants in striped catfish (Pangasianodon hypophthalmus) pond water for 42 days. The experiment simulated varying degrees of nutrient enhancement by using fish pond effluent enriched with three levels of nitrogen (N) (2.1, 4.3 and 8.6 mmol/l) and three concentrations levels of phosphorus (P) (0.16, 0.32 and 0.64 mmol/l) using NH4NO3 and KH2PO4, respectively. The treatments were arranged in a completely randomized design with four replications. Raw striped catfish pond water was served as background growth solution which was spiked with NH4NO3 (as a N source) and KH2PO4 (as a P source) and was renewed weekly. Nitrogen supply significantly affected most tested parameters whereas P only affected biomass, P content and N : P ratio content and accumulation in the roots and the shoots. H. acutigluma had significant higher growth, biomass and nutrient uptake when N concentration increased but not for the case of P increment. H. acutigluma helped to remove 7.6-19% N and 2.1-5.2% P from total input N and P concentrations in the experimental treatment. It indicates that Hymenachne appears to be a promising phytoremediation agent in nutrients removal from aquaculture water.

Md Nazrin Bin Muhamad, Roslina Mohammad*, Norazli Othman and Zuritah A.Kadir
Volume 8 | Issue 1 | Pages: 455-470 | PDF | HTML
Abstract: Workers who are involved with abrasive blasting operations potentially have significant threats to their occupational safety and health (OSH) and environment from exposure to various types of occupational hazards and risks. For example, due to the abundant amount of dust generated from abrasive blasting, workers are exposed to possibility of respiratory illness and the inhalation of airborne contaminants may cause silicosis which often leads to fatality after a certain period of exposure. Concurrently, the control measures that currently exist in the standard operating procedures (SOP) for abrasive blasting operations at pressure vessel fabrication plant companies located in the southern region of Peninsular Malaysia are insufficient to remove or reduce the hazards and risks of OSH. In contrast, any possible harm during abrasive blasting may result in workers potentially experiencing occupational injury or illness. The purpose of this study is to describe and analyse the potential risk of abrasive blasting in pressure vessel fabrication plants. This comprehensive study was done using risk assessment tools such as Hazard Identification, Risk Assessment, and Risk Control (HIRARC). The study is designed to identify and analyse the potential risks that result from recommendations that are properly followed with control measures ranging from elimination, substitution, engineering controls, administrative control, to personal protective equipment (PPE). This would be beneficial in proposing improvements to SOP of abrasive blasting operations that comply with Malaysian requirements, standards and regulations.

Abstract: A natural disaster is a serious event that contributes to the damage of infrastructures and property losses, the demand of budgetary allocation, disruption of economic and social activities, damages to the environment, and threat to human life. In disaster management, one of the aims is to reduce the impact of natural disaster through disaster risk management. However, the traditional data risk management mechanism to store and analyse huge disasters has become a challenge for relevant organizations due to its massive datasets, especially when it deals with big data and analytics. Therefore, the aim of this paper is to formulate a big data analytics model to strengthen the disaster risk reduction for Selangor State, Malaysia, comprehending both traditional datasets (geospatial data) and big data analytics (nonspatial data). To this end, 59 factors and available datasets were classified into six categories: ecology, economic, environment, organisation, social, and technology. These factors were derived from existing studies and then validated in a focus group discussion with 54 government agencies involved disaster risk management in Selangor State, Malaysia. The final output of this paper is Big Data Analytics Model for Disaster Risk Reduction, which will be useful to all stakeholders related to disaster risk management and disaster risk reduction initiatives.

H2S Removal from Sour Water in a Trickling Biofilter
Mojtaba Fasihi, Mohammad Hassan Fazaelipoor
Abstract: Long term desulfurization of sour water was studied in a co-current trickling biofilter (BTF) to find out an alternative to the traditional methods (stripping in a packed or try columns) being used in the gas and oil refineries. Microorganisms from an operating trickling biofilter, treating low levels of H2S (up to 5 g S-H2S m-3) and organic pollutants, were taken, enriched immobilized on the packing materials. A critical elimination capacity (EC) of 151g S-H2S m-3h-1 was achieved during stepwise increase of sulfide concentration from 10 to 50 g S-H2S m-3. H2S measurement along the bed showed that the most significant sulfide removal occurred at the top section of the BTF. Besides the H2S concentration, the effect of liquid velocity and aeration rate was investigated during two independent experiment. Results showed that aeration rate did not increase sulfate production and sulfate selectivity should be improved by regulating of the liquid velocity. It was concluded that biological treatment can be used as a viable alternative to traditional methods for H2S removal from sour water.

Volume 8 | Issue 1 | Pages: 504-520 | PDF | HTML
Abstract: In order to achieve sustainable performance, it was emphasized for an organization for improvement of the standard performance. This paper attempts to propose a benchmark for the standard time to complete daily paperwork received at a forwarding company by using the define-measure-analyse-improve-control (DMAIC) approach. Results showed that the import clearance agent required 3 days or more to clear paperwork for duty or tax confirmation. The impact led to delayed shipment delivery, caused by customer dissatisfaction and company loss of trusts amongst customers. It was also found that that the number of paperwork received daily was 516, distributed among an average of 15 employees, from January to April 2018. Each employee received an average of 34 paperwork daily. The amount of paperwork received by each employee was at alarming level. The time required to complete paperwork for duty/tax confirmation were 3 days or more for most of the employees, which stood at 62%. Therefore, based on the results of the findings, the proposed benchmark of the standard time for paperwork clearance should not be more than 1 day to allow for same day delivery to the customers, as per the commitment promised by the company.

Abstract: The Long Term Development Plan (RPJP) 2005-2025 emphasizes the establishment of a strong environment structure based on competitive advantage in various regions supported by quality and competitive human resources. To create high competitiveness in various regions, regional development approaches and strategies are not only about environment improvement, however, the equitable development in all regions and communities must be watched over. In 2020-2024, regional development is carried out through two main strategies, namely the growth strategy and the equalization strategy as reflected in the growth corridor approach and the island-based equal distribution corridor. The growth strategy is the transformation and acceleration of island and island development. The development focus is the important corridors on each island and archipelago that can drive significant growth in the next five years. The identification of growth corridors on each island and archipelago is carried out by considering the potential of its main economic bases outside Java. The environment bases that have been identified are natural resource processing centers, strategic tourism areas, service centers including metropolitan areas and new metropolitan supporting cities. In this main environment base, it is necessary to strengthen the facilities and infrastructure supply to support large environment activities, including transportation, electricity, communication tool, and infrastructure.

Volume 8 | Issue 1 | Pages: 551-555 | PDF | HTML
Abstract: The limited natural resource is a real challenge that can hinder the achievement of the goal of Environmental treatment. Holistic and integrated efforts from various sectors are needed to overcome the challenges of limited natural resources. In addition, the development planning needs to pay attention to balance the use of natural resources and the achievement of development targets and to pay attention to the reaction that the environment may depict against using its natural resources. In this regard, economists are taught that long-term economic growth should be maximized. However ecologists and environmentalists believe we can have too much of a good thing. The models used by mainstream economists do not properly take into account a few details – such as melting iceberg, shrinking resource stocks, or the opinions on all this of future generations. In fact, the real credit crunch is not the one involving banks, but the one involving the environment. For centuries we have been depleting forests, oceans, fuel sources, and other species, and the bill is about to become due. Economists’ cherished belief in economic growth is colliding with the reality that we are just one part of larger ecosystem. It explores new economic approaches that aim to resolve the conflict and bring our financial system into balance with the rest of the world.

Abstract: Indonesia as a country with high biodiversity has great opportunities to develop products from biodiversity. The biodiversity utilization through bioprospecting activities can meet the needs of raw materials for medicine, clothing, food, spices, animal feed, resin producers, dyes, and others. In addition, the diversification of primary medicinal plant products into secondary products has high economic added value. After the reform era in 1998, Indonesia has not been able to continue the socio-economic transformation that was stalled due to the crisis. Indonesia's average potential economic growth has continued to fall from 6.0 percent in the 1990-2000 period to an average of around 5.0 percent in the 2000-2015 period. This slow-moving structural transformation was also marked by the contribution of industrial GDP which fell to 19.9 percent. On the other hand, the contribution of primary sector GDP was 20.9 percent and the contribution of service sector GDP continued to increase to around 59.2 percent in 2018. The increase of GDP in the service sector shows a transition of growth sources from the primary to tertiary sectors. However, the economic transition has not been able to encourage higher growth. The service sector which absorbs labor migration from the primary sector is dominated by the informal services sector with a low growth contribution. The industrial sector, which has the greatest potential to drive growth, still faces the challenge of rising labor costs that have not been followed by an equal increase in productivity.
