Abstract
The aim of this study was to investigate the optimal conditions for sulphate from wastewater by Escherichia coli and Psendomonas aeruginosa under shake flask conditions. Before inoculating with the respective isolates, the wastewater was first filtered in 200 mL quantity into 250 mL capacity and then sterilized in an autoclave. After inoculation with the test isolates, aliquot wastewater samples was aseptically removed from each flask, every 24 h, for 96 h, for the estimation of sulphate concentration, using procedures. The results revealed sulphate removal at 35 oC and 45 oC while at 25 oC, an increase in sulphate level in the wastewater was observed at the end of the 96 h incubation period. This trend was irrespective of the test bacterial species. At the different pH, sulphate decreases of 50.31 %, 26.67 % and 18.14 % at pH 6, 8 and 10 were observed in the presence of the Escherichia coli while in the presence of the Pseudomonas aeruginosa, sulphate decreases of 31.53 % and 21.52 % were observed at pH 6 and 8, respectively. With the different concentrations of sodium acetate that were used for investigation, maximum sulphate removal was observed at 10 g/L. This trend was also irrespective of the test isolates. In presence of the different external carbon sources, sulphate concentrations in the wastewater after the 96 h incubation period were observed to increases at the expiration of incubation. Yeast and meat extracts were observed to enhance sulphate removal in the presence of the Escherichia coli while in presence of the Pseudomonas aeruginosa, remarkable sulphate removal was only observed when yeast extract was used as the nitrogen source. There was no decrease in sulphate level at the different concentrations of peptone that were investigated. This trend was common in presence of both isolates. The study was able to reveal the roles of temperature, pH, carbon and nitrogen concentrations and carbon/nitrogen sources on sulphate removal from wastewater by the test is bacterial species under the experimental conditions used for investigation.

Update on Nutritional Aspects of Gluten-Free Diet in Celiac Patients

Research Article
Author(s): Maria de Lourdes Moreno, Isabel Comino, Carolina Sousa
Journal: Journal of Nutrients

Export to    BibTeX   |   EndNote   |   RIS

Abstract
A strict gluten-free diet is the only currently available therapeutic treatment for patients with celiac disease, an autoimmune disorder of the small intestine associated with a permanent intolerance to gluten proteins. In recent years, the dramatically prompted changes in the dietary habit of an increasingly large population (celiac disease, non-celiac gluten sensitivity and gluten allergy) has resulted in rising demands for gluten-free products. Before starting gluten-free diet, alteration in intestinal absorption capacity of celiac patients involves deficiencies of nutrients, vitamins and dietary minerals. The habitual poor gluten-free food choices in addition to inherent deficiencies in the gluten-free diet of diagnosed celiac patients may relate with dietary inadequacies. Therefore dietary assessment and counseling at the time of celiac disease diagnosis and ongoing care are crucial as well as fortification of gluten-free foods also need to be considered. This article reviews the nutritional aspects of gluten-free diet in celiac patients and provides an up-date of dietetic recommendations to correct these deficiencies and to ensure optimum gluten-free diet compliance.
Contribution/ Originality
This study documents the nutritional aspects of gluten-free diet in celiac patients, with special highlight on the assessment of the nutritional status of the patient prior to withdrawal of gluten from the diet.

Abstract
This study analyzes factors associated with land rental market and its implication on food security in rural households of Malawi. Land rental markets transfer land from land rich but resource poor to land poor but wealthy households. It is also a remedy to scarcity of land due to soaring population growth and hence high pressure on farm land. A binary probit model was applied for participation, and censored (Tobit) for degree of participation for both tenants and landlords to pin down socio-economic factors affecting the land rental market using 450 randomly sampled households across six districts. Treatment effect model was used to test whether land market participation improves food security of the participants. After controlling for soil characteristics and agro ecological factors, the study revealed that rental participation has significantly improved the tenant’s food access in terms of staple food (maize) but has no positive significant effect on the landlords’ maize output.
Contribution/ Originality
This is one of the very few studies which have investigated the link between land market and food security in Malawi. A rare research showing how land rental markets have been used to transfer land from land rich but resource poor to land poor but wealthy households.

Journal: Review of Plant Studies

Export to    BibTeX   |   EndNote   |   RIS

Abstract
 Competition and interaction among organisms in nature results to selection for traits which confer added advantage. As a result of such interactions between plants and their natural enemies, plants have developed defensive mechanisms, both chemical and physical, to minimize pest damage. Intensive researches were carried out to identify and isolation the gene responsible for resistance plant to insects’ infestation which is used in breeding programs for crops improvement. It can be summarized as follows: 1-  Corn ear worm, Helicoverpa zea (Boddie) can’t cause damage to certain corn strain due to maysin, a C-glycosyl flavone, and related compounds in the silks that inhibit corn earworm larval growth. Scientist can identify corn chromosome regions associated with silk maysin concentration, and then used it in producing new hybrid.2- Other insect such as the fall army worm, Spodoptera frugiperda can’t cause damage to resistance corn due to some factors as high hemicelluloses content, low protein content and leaf toughness. They can also identify a gene code which is controlled by the resistance traits of corn to the fall army worm. 3- However, the European corn borer, Ostrinia nubilalis (Hubner) can’t cause damage to certain corn varieties due to high concentrations of 2,4-dihydroxy-7- methoxy-1,4-benzoxazin-3-one (DIMBOA) in the leaves of mid-whorl stage plants. Scientist indicated that resistance to the European corn borer was identified in Peruvian corn germplasm and the GEM (Germplasm Enhancement of Maize) corn collection, then make backcross to produce new resistance strain. 4- Other crops as tomato infested by Tuta absoluta  (Meyrick ( but some tomato varieties as Lycopersicon esculentum can resist it due to antixenosis factor which interrupted tomato leaf miner from feed, oviposition and shelter . 5- Russian wheat aphid, Diuraphis noxia (Mordvilko), can’t cause damage to some wheat and barley and others crop due to antibiosis and antixenosis factors. Six sources of resistant wheat, each governed by a different, single gene, have been identified.6- Two-spotted spider mites, Tetranychus urticae (Acari: Tetranychidae) and Whiteflies, Bemisia tabaci (Hemiptera: Aleyrodidae) are herbivorous pests. Additional whitefly infestation to spider-mite infested plants resulted in a reduced attraction of predatory mites (Phytoseiulus persimilis). This interference was shown to result from the reduction in (E)-β-ocimene emission from plantsinfested by both spider mites and whiteflies.7- Transgenic crops expressing a protein from the bacterium Bacillus thuringiensis Berliner (Bt) were carried out into potato, maize, cotton and soybean to be reduced their insect infestation.
Contribution/ Originality
This study contributes in the existing literature which interested to study factors of plant resistance to agriculture insect pests and its’ role to improve new plant strains.

Author(s): Shoewu, O, Akinyemi, L.A, Edeko, F.O
Journal: Review of Environment and Earth Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The nexus of this study is to examine thoroughly the dependence of climatological parameters on GSM signal, especially in a metropolitan terrain. To validate this work, field measurements were carried out in the ITU regions of Lagos metropolitan area. The measurement system consisted of live documented radio base stations (BS) data transmitting at 13GHz, 15GHz and 23GHz in seven sites that constituted a metropolitan environment. The seven sites were segmented into non-urban (rural), suburban, urban, Ex-urban, dense-urban, micro-urban and peri-urban propagation environment. The Rain outage of the annual unavailability of the region of metropolitan data was collected using a Lenovo Laptop with installed path loss software alongside a licensed key called DONGLE. Results of this effort reveal that climate change affects signal propagation.  
Contribution/ Originality
This study reveals how climate change affects the signal propagation of radio waves in two different seasons. It also explores some of the areas that were not considered such as suburban, peri-urban areas by other authors. This paper primary contribution is in the determination of unavailability of rain outage from the metropolitan areas. This research study therefore shows that climate affects signal propagation depending on climatic parameters (rain and harmattan), frequency of transmission and ITU regions of propagation (which justifies the size of rain and harmattan intensity) in Nigeria.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
It is a complex task to optimize query as well as to validate the correctness and effectiveness of query optimizer. A query optimizer should estimate and compare the costs of executing a query using different execution strategies and should choose the strategy with the lower cost estimate. To fairly and realistically compare different strategies accurate cost estimation is required. This is a challenging task to measure quality of query optimization as modern query optimizers provide more advanced optimization strategies and adaptive techniques. This paper describes different ways to improve the performance of SQL Server queries, index optimization with occasional references to particular SQL code and how to achieve the best performance for the given tables and queries by giving some tips for query optimization in Microsoft SQL Server. The paper provides a detailed overview of query optimization, Optimization techniques, testing of optimization techniques that are used to validate the query optimizer of Microsoft’s SQL Server and issues in query optimization testing.

Abstract
Information and communication technology have taken centre stage of almost every interaction, communication and learning processes among people of this world. This study is a comparative analysis of the usefulness of modern information and communication technology (ICT) in the transmission and movement of information in the teaching and learning processes at high schools in Zimbabwe. In the contemporary times most projected media are computerized and, thus, may require advanced expertise in operating them. It has been also argued that projected media makes learning real, practical, interactive, and above all, more permanent than other teaching and learning aids. The objectives of this study were to establish forms of projected media in use in urban and rural schools in Zimbabwe; to investigate the extent to which these projected media are really of use in these schools; and to establish challenges faced by these schools in their endeavours in the use of projected media. The central argument in the study is that proper use of projected media leads to efficiency and effectiveness in the teaching and learning processes. Research methods involved both a theoretical review and an empirical study based on case studies, making use of comparative and exploratory approaches. The study established that while urban secondary schools have some forms of contemporary projected media, rural secondary schools do not have most of these projected media; the expertise and zeal to use the projected media is very low in both urban and rural schools; and proper use of projected media leads to efficiency and effectiveness in the teaching and learning processes. Among other recommendations, the study recommends continuous professional development of teachers in the use of projected media; and partnerships with stakeholders so that the school has a wider base for resource mobilisation.
Contribution/ Originality
The overall aim of this study is to contribute a theoretical framework that will help towards the generation, development and use of ICTs and projected media in both urban and rural secondary schools in Zimbabwe and the world. Our aim is to widen the knowledge base and understanding of the generation, development and utilisation of ICTs and projected media in Zimbabwe and the global community.

Journal: Animal Review

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The composition of cattle diets is one the most important parameters influencing meat quality .Effects of pasture alone and supplementation with dehaydrated Medicago sativa on carcass and meat quality were studied in Marchigiana beef cattle, in particular lipid and stability.Meat quality measurements were made on Longissimus dorsi (LD) muscle in 20 animals slaughtered at 660-700 kg.The amount of lipids in the control group was lower with higher percentage of polyunsaturated fatty acids (PUFA), especially linoleic (C18:2) and linolenic (C18:3) acid. There were significant differences (P≤0.01) of TBARS values that were higher in the group fed with supplementation of Medicago sativa than in the other group, the control one.
Contribution/ Originality
Today people try more and more to replace soybean with other GMO-free protein foods. This study documents how the use of dehydrated Alfalfa meal in calf nutrition instead of soybean enriches the meat in polyunsaturated acids but, at the same time, promotes the processes of lipid oxidation.

Abstract
The influence of seleno-cystine (CySe2) added to ovine ruminal fluids containing α-linolenic acid (αLNA) on the profile of fatty acids (FA) was investigated. Fluids were incubated in vitro at 39°C under CO2 either alone (RF) or with αLNA (1.67 mg/ml) or with a combination of αLNA with either a low (1.34 μg/ml) or high (3.33 μg/ml) level of Se as CySe2. Fluids were removed after 0, 6, 12, 18, 24 hrs of incubation and then analyzed to determine FA levels. αLNA added to the fluids without/with CySe2 decreased the C18α0 concentration for incubation at all times from 6 hrs compared with the RF or the fluid containing CySe2. αLNA added to the fluids without/with CySe2 decreased the biohydrogenation yield to C18:0. CySe2 added to the fluids decreased the C18:0 concentration and the index of the biohydrogenation to C18:0 compared with the RF. The higher concentration of CySe2 in the fluids with αLNA reduced the accumulation of trans11C18:1 for incubation at all times from 18 hrs compared with the fluids with αLNA, irrespective of the presence of the lower concentration of CySe2. The lowest concentration of trans11C18:1 in the fluids with LNA and the higher concentration of CySe2 correlated with the lowest yield of the isomerization of αLNA into cis9trans11cis15C18:3 and the lowest yield of the initial biohydrogenation of cis9trans11cis15C18:3 to trans11cis15C18:2 in the fluids containing αLNA and the higher concentration of CySe2. CySe2 added to the fluids with αLNA decreased the ratio of polyunsaturated FA to saturated FA for incubation at all times from 12 hrs compared with the fluids containing αLNA. CySe2 in the fluids without/with αLNA reduced the FA sum in the fluids.
Contribution/ Originality
Our original study documents that CySe2 added to the ovine ruminal fluids, irrespective of the presence of αLNA, affects concentrations of fatty acids, the capacity of the bacterial isomerases and the biohydrogenation yield of unsaturated fatty acids in in vitro incubated ruminal fluids compared with the control fluid.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The multi-level inverter system is mostly used in ac drives, when both reduced harmonic contents and high power are required. In this paper a new topology of multilevel inverter is introduced. This type has many steps with less power electronic switches. Due to the less number of switches the cost of the inverter is very less and also less installation area is required. Firstly, we describe briefly the structural parts of the inverter then switching strategy and operational principles of the proposed inverter are explained and operational topologies are given. Simulation is performed using MATLAB SIMULINK. Various conventional PWM techniques are applied to the circuit such as PDPWM, PODPWM, APODPWM, VFPWM and COPWM. By comparing among the conventional PWM techniques, PDPWM provide the less THD value and COPWM provide a higher fundamental RMS output voltage.
Contribution/ Originality
This study contributes various PWM techniques and hence this work presents a novel approach for controlling the harmonics of output voltage of chosen MLI employing  Sinusoidal references for different PWM switching strategies.

Journal: Review of Industrial Engineering Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The importance of carbon steel in the petroleum industries cannot be over emphasized. The carbon steel is susceptible to internal corrosion due to H2S/CO2 environment. The two gasses, in combination with water, defines most of the corrosion problems in the oil and gas production. This research paper is aimed at investigating the corrosion rate of steels in water and H2S. Eight steel samples (AISI 301, AISI 302, AISI 304, AISI 304L, AISI 308, AISI 309, St 35 and St 37) were used for the experiment. The results obtained showed that the corrosion rate in water saturated H2S was higher as compared to wet and dry H2S gases. This was attributed to the aqueous state of water saturated H2S, which increases the rate of ion dissociation. The high rate of ion dissociation increases the rate of ion penetration into the steel (diffusion rate) and thus the corrosion rate.
Contribution/ Originality
The paper primary contribution is the findings that corrosion rate is higher in water saturated hydrogen sulphide as a result of its aqueous state which increases the rate of ion dissociation. Also, stainless steels are more resistance to corrosion than carbon steels.

Abstract
This paper emphasizes on the efficiency of small and medium scale assets for the social development agendas like entrepreneurship development, poverty alleviation etc. We will scrutinize the overall effectiveness of the Bangladesh Bank (2014) financing industry of the country. Informative resource has been collected by an original field survey and from secondary resources. The field survey includes 100 stakeholders regarding SME financing 60 of who were direct loan facilitators of the financiers. The results conclude that almost all factors related to SME financing industry of the country are satisfactory except some of them. However, some recent contradictory occurrences are taking breath on the neck of this industry. The industry is running without a concrete framework and without an acceptable asset recovery system. On the other side the industry is facing imperfect competition. This work will be successful only if the financiers will rejuvenate the overall financing system by fortifying our results. This research paper has an emphatic gaze on entrepreneurship development by alleviating poverty by SME financing.
Contribution/ Originality
This research paper is based on empirical data and reveals some results to exhibit that how SME financing effects on some socio-economic phenomena of Bangladesh like entrepreneurship development, poverty alleviation, women entrepreneurship development etc. considering the context of Bangladesh.

Journal: Review of Knowledge Economy

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Because the qualitative and quantitative data can be analyzed by both qualitative and quantitative methods, some scholars argue that the combination of theme can be more effective but others argues that the distinction between qualitative and quantitative data have certain utility, though most people draw to hard a distinction. Although, the quantitative-qualitative distinction can lead to some sorts of confusions due to their distinct ontological and measurement related issues; the qual-quant distinction debate is philosophical, not methodological.
