Authors: Adedeji Oludare H. , Olayinka Oluwafunmilayo O.
Published: August 2019

This paper assessed physicochemical properties (temperature, pH, acidity, alkalinity, colour,odour, taste, EC, TDS, TH, turbidity, bicarbonate, phosphate, nitrate, Ca2+, Mg2+, Na+, K+, Cl-& SO42-as well as heavy metal concentrations heavy metals (Cd, Cr, Cu, Fe, Pb and Zn) of selected wells and borehole near textile industries in Ikorodu, Nigeria. The physicochemical parameters were analysed using standard methods by APHA, while heavy metals were analysedusing atomic absorption spectrometer (AAS). The pH of water from the boreholes and hand-dugwells ranged from 5.90 to 6.70. The well water had higher total hardness, calcium, magnesium, sulphate and chloride compared to the boreholes. Alkalinity in the boreholes ranged from 740.2to 820.4 mgL-1compared to wells that ranged from 144.4 to 670.2 mg L-1. EC for the boreholes rangedfrom 124.5-182.3 μScm-1compared to EC of wells that ranged from 216.2-385.6 μScm-1. TDS rangedfrom 48.6-60.3 mg L-1in the borehole compared to 62.5-120 mgL-1in the wells. Concentration of Feranged from 0.12 to 1.2 mgL-1in the boreholes compared to 1.2 to 1.60 mgL-1found in the wellwater. Zn, Pb, and Cu ranged from 0.60 to 1.20 mgL-1, 0.02 to 0.03 mgL-1and 0.04 to 0.06 mgL-1respectively. Concentrations of Fe and Pb were above the permissible limits of WHO and NIS.A possible source of pollution is seepage of effluent discharge through the porous soil into thegroundwater and this poses great danger to the health of the people who consume the water.

Published: August 2019

This study investigates application of the reduction melting method to recover metals fromelectronic wastes. The study began with determination of the optimal conditions for metal recovery from cathode ray tube (CRT) glass by melting under various conditions. The reco-very of metallic lead and lead oxide (PbO) remaining in the glass residues for each set of melting condition were compared. It was found that the optimal condition for metallic Pb recovery from the CRT glass was melting the glass at 1200oC for 1 hand then soaking at precipitation temperature of 500oC for 1-2 h. Under these conditions, recovery rates of metallic lead from CRT glass reached up to 85-89%. The optimal conditions identified in this preliminary study were then used to recover metals from a mixture of CRT glass and printed circuit boards (PCBs), as a proxy for electronic waste. Electron Probe Micro Analysis (EPMA)characterization indicated two categories of metal deposits; the first being metallic lead (Pb) and the second as a mixture of copper (Cu), tin (Sn), and antimony (Sb). The study also confirmedthat incorporation of PCB did not affect lead recovery from CRT glass.

Published: August 2019

KaengKhoi District (SaraburiProvince, Thailand) suffers from a surface water shortage due to increasing demand from domestic use and crop production, particularly in the drought season. Groundwater resources are an additional source of freshwater in this area, especially for agricul-tural purposes, but to be sustainable its usage should not exceed long-term groundwater recharge. Evaluation of the groundwater recharge potential is therefore essential to determine the sustain-able use level for groundwater resources. This study aimed to determine the groundwater re-charge potential using the geographic information system (GIS) around the Land Development Facilities of Chulalongkorn University at KaengKhoi District, Thailand. The hydrologic and geo-logic features affecting groundwater recharge potential into the groundwater system are the linea-ments, drainage density, lithology and land cover/land use. The weighting of these factors were derived from integration of the interrelationship of the major and minor effects of each contri-buting factor. Then GIS overlay was used to determine the influence of the hydrologic and geo-logic effects on total groundwater recharge potentiality, classified into five categories: very high, high, moderate, low and very low. The highest recharge potentialzone was located in the down-stream areas. The map generated revealed that about 50% of the study area had a medium ground-water recharge potential, mainly located in the eastern upstream part and the central area.

Published: August 2019

The analytical hierarchy process (AHP) is an approach for decision making with complex problems that can be applied in water resources management. This paper reviews the literature onapplication of AHP in water resource management from 2009-2013 in 46 peer reviewed journal articles, analyzes the strengths and limitations of the technique using SWOT analysis, and then focuses on its utility when integrated with other methods for water resource management in Thailand. The findings indicate that AHP can be utilized for all types of water resource manage-ment focused on criteria concerning social, economic and environmental factors. Furthermore, the efficacy of AHP can be enhanced when integrated with other techniques. Application of AHP in Thailand could be combined with the Delphi technique to identify key criteria for resolving bias problems regarding goal and criteria.
Greenhouse Gas Emission in Jewelry Industry: A Case Study of Silver Flat Ring
Authors: Usapein Parnuwat , Tongcumpou Chantra
Published: August 2019

This paper describes an assessment of the carbon footprint (CF) of a silver ring, together with an attempt to measurematerial and energy consumption. The boundary of analyzing CF was defined as Business to Business (B2B). All primary data were obtained from a survey of the case study factory. Acquisition of raw material (silver) was the main GHG contribution to the overall CF and was thus considered as a CF hotspot. Acquisition accounted for 0.9740 kg CO2e or 94.44% of total emissions, followed by production processes (0.0573 kg CO2e) and tran-sportation (0.002 kg CO2e). The total CF amounted to 1.03 kg CO2e per silver ring product. To reduce the CF, it is suggested that choosing low GHG production processes could result in significant reduction in total CF. In addition, the study proposes options for recycling waste and using high performance electronic equipment.

Published: August 2019

The objective of this paper is to review the integration of health impact assessment (HIA) into environmental health assessment (EIA) or EHIA, existing legal requirements for health risk analyses, and lessons learned for integrating HIA within EIA processes. The authors undertook literature searches for EHIA practices through academic publications, reports, and websites of pub-lic organizations and related agencies in Thailand. We examined and synthesized the HIA system development, regulations, and examples of integrated EHIA. In conclusion, the implementation of EHIA still faces many obstacles, especially in such com-plex sector policy environments. The uncertainties, lack of evidence base, and challenges in imple-menting EHIA within the prevailing political and cultural contexts constrain decision-making andremain under-developed. Methodologies and tools have to fit with the available data and resources. The EHIA evaluation requires analytical validity, relevance, stakeholder engagement, and public involvement. The review resulted in the following recommendations to increasing Thailand’s EHIA capacity: 1) develop tools and guidelines for implementation in each project types; 2) train EHIA experts and conduct EHIA courses to build capacity; 3) ensure meaningful participation of private sector and the public; 4) bring together all parties in the debate, and build consensus throughcommunity participation and the upholding of environmental justice including EHIA communication; and 5) work to ensure strong public participation and political engagement.

Authors: Manomaivibool Panate , Chart-asa Chidsanuphong , Unroj Pattayaporn
Published: August 2019

This study measured the impact of an awareness campaign to reduce food waste on campus. Information cues were installed at strategic locations in a canteen to engage university students in food waste prevention. Stickers with food ordering tips were placed in front of the food vendors. Information cards about resource use in food production were placed on dining tables to remind students to finish what they had ordered. Other materials of the save food campaign such as pos-ters and banners carried messages and images to elicit a pro-environmental norm. Students were also encouraged to share their support through social media in order to increase the visibility of the actions. The analysis showed that carefully designed information was effective in changing be-haviors. Based on the visual analysis of returned food containers, the share of those who finished all their food nearly doubled after the campaign. The types of food waste on the information cardswere also significantly reduced. However, the results showed that voluntary behavior changes are limited to actions requiring little additional effort. Other types of interventions such as rule-based measures, economic incentives and changes in physical settings and how food is served should be considered to further food waste prevention. In addition, reuse and recycling options are needed for fluid and other unavoidable food waste.
Application of Life Cycle Assessment Method for Environmental Impact Assessment of Fired Brick Production Plant in Thailand
Authors: Na Talang Rutjaya P. , Sirivithayapakorn Sanya
Published: August 2019

In many Asian countries, fired bricksare producedby burning raw bricks in a rudimen-tary clamp kiln without pollution control mechanisms, a practice which contributes to several kinds of environmental impact. This research investigated the inputs and outputs associated with production of fired bricks using the rice husk-fuelled clamp kiln. Data collected includedraw material use, energy, products, emissions and kiln temperatures. To quantify environmental impacts, the consequential-focused life cycle assessment (LCA) approach was adopted. The impactswere assessed in terms of fuel substitution as the acquisition of another fuelwas re-quired to substitute for electricity. The findings indicated that the clamp kiln technology pro-duced lowCO2emissions per unit of production and per unit of energy input, despite poor specific energy consumption. The LCA analysis indicated that the use of rice husk was the major contributor to environmental impact, and that abiotic depletion of fossil fuels repre-sented the environmental hotspot. To improve combustion efficiency, the clamp kilns should beeither insulated or replaced with more efficient kiln technology, in conjunction with the use ofrice husk.

Published: August 2019

A survey of an outbreak of fungal diseases of rice variety Phitsanulok2 (PLS91014-16-1-5-1) was conducted in Thailand during June 2014 to January 2015 using aW-random sampling pat-tern. The study revealed the incidence of several diseases including brown spot (Bipolaris oryzae), narrow brown leaf streak (Cercospora oryzae), and dirty panicle (Alternaria padwickii, C. oryzae, Curvularia lunata, Fusarium semitectum, and B. oryzae). This study evaluated the ef-ficacy of wood vinegar for control of these fungal diseases. A compleel randomized design was used, using the above variety in 3 replications. In the laboratory we found wood vinegar to be effective in inhibiting growth of representative pathogens such as C. lunata,B. oryzae,F. semi-tectum, and A. padwickii, the causal agent of dirty panicle disease. The field results confirmed the efficacy of wood vinegar under greenhouse conditions, with significantly reduced disease incidence of brown spot and dirty panicle, and significantly enhanced germination, seedling vigor,shoot height, root length, and fresh weight, when compared with the untreated control. However, seed treatment and 6 foliar sprays of wood vinegar under field conditions at Ang Thong showed no significant differences from the conventional treatment in suppression of brown spot, narrow brown leaf streak, and dirty panicle. The result demonstrates a promising alternative approach to control of key rice diseases.

Authors: Jongdee Sunisa , Kumsaen Tinnakorn , Wantala Kitirote
Published: August 2019

The aim of this research was to investigate interactions in the removal of manganese from contaminated water by oxidation through an ozonation process. The manganese oxidation was used to oxidize manganese ions (Mn2+) in solution to manganese dioxide (MnO2) in its brown solid form, in order to reduce levels of manganese ions in the water to below the acceptable limit for drinking water (0.05 mg L-1). In this study, the independent effects such as the initial concentration of manganese (5, 10 and 15 mg L-1), initial pH of solutions (3, 4 and 5) and ozone concentrations (10.970, 21.945 and 32.920 mg L-1) designed Box-Behnken Design (BBD) as a one of the design of experiments were examined foroptimal conditions and including main effects and their interactions. The ozone concentration in the reactor was increased with increasing operating time of an ozone generator and linearly increased at the rate about 2.194 mg O3 L-1 min-1. The experimental results indicated that all factors significantly affected manganese removal rate. Initial manganese concentration was negatively correlated, while pH and ozone concentration were both positively correlated with removal percentage. Main, square and interaction effects were significant on percent manganese removal. Additionally, percent removal was reduced with increasing ozone concentrations because at higher ozone levels, MnO2 in solid form was converted to MnO4- and re-dissolved into solution- a process known as over-oxidation. The maximal condition, the removal efficiency of manganese in oxidation reaction by ozonation process in initial manganese concentration 5 mg L-1, pH 4.0 and ozone concentration 21.945 mg L-1 was appeared more than 100 %. The present study indicates that manganese ions can be effectively removed from drinking water by ozonation.

Published: August 2019

The testing and use of microorganisms for in vitro growth promotion of agriculturally significant crops such as rice has increased but remains underexploited. The current study aims to explore growth-enhancing mechanisms of dominant root-associated fungi (RAF) isolates from Drynaria quercifolia and test their effects on rice. The most abundant RAF on five tree-collection sites were cultured in vitro. Genomic DNA of the RAF were extracted and the ITS (internal transcribed spacer) region of the 18S ribosomal DNA (rDNA) were sequenced and molecularly identified. Two RAF isolates significantly increased the plant shoot/total length (Meyerozyma guilliermondii: 10.29±4.18/13.46±4.18 cm; Trichoderma simmonsii: 10.33±1.38/13.23+1.58 cm), shoot/total fresh weight (Meyerozyma guilliermondii: 57.33±15.76/71.00±16.10 mg; Trichoderma simmonsii: 63.22±12.23/76.00±10.67 mg) and shoot/total dry weight (Meyerozyma guilliermondii: 16.99±6.74/22.78±7.41 mg; Trichoderma simmonsii: 16.89±3.33/23.11±5.30 mg) weight comparedto the negative control. These results possibly show the ability of the two isolates to produce the hormone gibberellic acid. On the other hand, three of the RAF isolates did not significantly increase seedling growth and biomass. The Trichoderma yunnanense (shoot: 0.36±0.16 cm; total: 0.53±0.20 cm), unidentified Mucoromycotina isolate F5P1RAF16 (shoot: 1.87±0.59 cm; total: 2.12±0.58 cm) and the unidentified Mucoromycotinaisolate F9P2RAF21 (shoot: 3.26±1.56 cm; total: 5.19±2.00 cm) approximated the growth of rice seedlings inoculated with broth and water negative control (shoot: 4.40+2.27 cm; total: 6.38+2.28 cm). This possibly indicates the inability of these isolates to produce GA or their potential ability to produce growth-retarding metabolites. Preliminary data from this study reveal potential growth-promoting capacity of RAF isolates on rice.
The exchange in family discourse
Authors: Clancy Brian
Published: August 2019

The intimate genre of family discourse has traditionally posed problems for linguists because of the difficulty in collecting the data and the intimate nature of the genre. For obvious reasons, people view family life as intensely private and so are unwilling to allow linguists to intrude upon it. This, to a certain extent, would explain the paucity of directly relevant material available. This paper is an attempt to address this lacuna, and perhaps more ambitiously, to provide openings for further study. The paper analyses the structure of the exchange in family discourse in an Irish context. A traditional model of conversational exchange is applied to the data but is seen as unsuitable for the analysis due to factors particular to family talk. However, later work in the area of the exchange brings into relief a clear exchange structure in this discourse, which, on the surface, appears dense and chaotic.

Now a days internet and other electronic devices have become an non removable part of our society. Day by day we are increasing the usage of data for transmission and storage as well. But there is always a problem for our data to be in wrong hands or hacked by someone. In order to ensure our secrecy of data we use bunch of algorithms to secure it. These algorithms comes under the vast section of cryptology, which means an art of hiding the data to make it secure. But as we all know when there is a hacker he would find every possible way to bypass the security algorithms. Some of the attacks are very popular in cryptology like Brute Force Attacks which checks each possible key combination to hack the data message. Due to the arrival of quantum computers in upcoming future hacking time will be decreased about a factor of around 1000 times. Now the best possible solution for enciphering data is Advanced Encryption Standard .This algorithm consists of two basic things static Substitution Box (S-Box) and other register operation. In this paper we have introduced a new technique to ensure a secure communication by using a dynamic S-Box with avalanche value of 58.59% as well as we also improved the overall area, delay (1.227 ns) and optimized the power to possible extents. Our results also approached above the traditional AES security as our modification improves avalanche effect also.

The steep rise in earth temperature also tends to rise in energy consumption for the sake of which demand for cooling also increases. Various cooling equipment’s are available within the market within different working principle, in which vapour compression system being the most common. But due to its design it is not easy to make it portable in which use of Peltier comes in place. Peltier being solid state in nature also has a benefit of being small in size as well it runs completely on Direct current. But due to lower efficiency of Peltier module the use is limited to some specific purpose. The heat dissipation of Peltier is higher than that of the absorption which intends require continuous removal of heat. For which liquid cooling outperform all in coefficient of performance. There are various coolants that can be incorporated within the system, in which water being the most common. So as per this research, water is compared to that of ethanol which being less common in terms of coolant. The study majorly concerned into various analytical part used for the calculation of COP of Peltier module in both the cases. Since our system doesn’t concern about overall system performance at present it is only concerned with the module efficiency so system COP was omitted in case of calculation and comparison. In the study it was obtained that for water and ethanol subjected to both natural and fan assisted radiator cooling a COP of 0.402, 0.413, 0.409 and 0.412 was obtained respectively for both coolant and cooling methods. Water was found the most suitable medium of cooling in regard to ethanol as due to tendency of heating up.

This paper mainly discusses the formulation of stochastic linear statistical model and its assumptions and finally explores an important aspect namely the Ordinary Least Squares (OLS) estimation of stochastic linear regression model. In addition to these inference in stochastic linear regression model is also presented here. Nimitozbay et.al [1], in their paper proposed the weighted mixed regression estimation of the coefficient vector in a linear regression model with stochastic linear restrictions binding the regression coefficients. In 1980, P.A.V.B. Swamy et.al proposed a linear regression model where the coefficient vector is a weekly stationary multivariate stochastic process and that model provides a convenient representation of a general class of non-stationary processes. They proposed prediction and estimation methods which are linear and easy to compute. Daojiang et.al [2] in 2014, in their paper depicted an innovative estimation technique to the multicollinearity in statistical model which is linear in the case of existence of stochastic linear constraints on the parameters and a very different estimation technique was presented by mixing the OME and PCR estimator also known as SRPC regression estimator. In 2014, Shuling Wang et.al [3] in their paper proposed some diagnostic methods in restricted stochastic statistical models which are linear. Gil Gonjalez et.al [4], in 2007, in their paper, derived the LSEs for the simple linear statistical model and examined them from a theoretical perspective.

The main objective of this research article is to propose linear programming problems for estimating the technical efficiency of DMU. This research article deals with the Shepard’s [1] input distance function and its properties are also evaluated. In addition to these extreme efficiency, efficiency but not extreme, weak efficiency and inefficient of a DMU are specifically examined here. In DEA the nature of returns to scale can be inferred. But we cannot quantify the returns to scale. The computations for the classification of RTS of a DMU are also derived in this discourse. In 2009, Barbara A. Mark et.al [2] in their paper, depicted an innovative method which is non-parametric to estimate technical efficiency. In 2011 S. Nuti et.al [3] inquired into the interrelations among technical efficiency scores, weighted per capita cost and overall performance. Gahe Zing Samuel Yannik et.al [4] used DEA to calculate technical assessment in banking sectors.

Social media content on the internet is increasing day by day. Since media knowledge helps people in making decisions, web based businesses give their clients an opportunity to express their opinions about items available on the web in the form of surveys and reviews. Sentiment analysis can be used on product reviews or tweets, comments, blogs to infer individual’s feelings or attitudes. Here Aspect Based Sentiment Analysis is used to extract most interesting aspect of a particular product from unlabeled text. We have developed two models for aspect/feature extraction.Model1 uses POS tagging whereas Model2 utilizes TFIDF .In Model 1 we start with noun phrase algorithm and extend it to adjectives and adverbs to extract all the aspect terms. In model2 after data preprocessing TDIDF technique is used. The relative importances of the aspects are calculated and the most important positive, negative and neutral aspects are presented to the user. Naïve Bayes, Support Vector machine, Decision Tree, KNN were used to classify the sentiment polarity of the generated aspects.

Some of the problems associated with the transportation of crude oils are due to the presence of heavy compounds as asphaltene molecules. This work developed a stochastic model that predicts the fractal dimension of the asphaltene aggregates. It was found that the maximum value of the fractal dimension is 1.71, which corresponds to the reported experimental results. The model can be applied as a universal growing behavior for the analysis of surface roughness when solids deposition is observed in the production systems involving crude oils.

Road traffic injuries and mortality are mainly caused by motorcycle crashes. Practically, 50% of people who meet their death in road traffic accidents (RTAs) are motorcyclists. The issue is increasingly articulated in progressing nations where the use of motorcycles has gained popularity in the past decades. Moreover, death and fatalities caused by accidents involving motorcyclists are also in the rise due to the increasing trend. Hence, motorcyclists are encouraged to use alternative modes of transportation that are safer in the attempt to minimise losses. As a result, a policy ought to be created to enhance urban transportation service and control motorcycle proprietorship. The current research that lays the groundwork aims to contribute a more elaborated analysis on motorcycle user mode decision conduct as well as an excellent comprehension of the conceivable efforts that can be taken to support motorcyclists to shift to a safer mode of transportation, particularly bus. In the current research work, the binary logit mode choice model was created for two elective modes in order to distinguish the separate practices of motorcyclists and bus users and assess their reactions to a situation that can minimize both time and expenses involved in bus travel. In addition, it should be noted that this paper surveyed a total of 327 travellers from Greater Cairo Region (GCR) in Egypt, the bus users were identified through revealed preference, while the motorcyclists were identified through revealed and stated preference surveys. In this case, travel time, travel cost, age, sexual orientation, income level, trip purpose, education level, and privacy significantly influence motorcycle user mode decision conduct. The likelihood of motorcyclists to utilize the use of buses was additionally analyzed dependent on a situation of minimized bus travel time and travel cost. These elements are very important in a program that attempts to draw in motorcyclists to utilize public transport, particularly bus.
