Abstract: Trace metals concentration and proximate composition of raw and boiled silver pomfret (Pampus argenteus) from coastal area and retail market were determined to gain the knowledge of the risk and benefits associated with indiscriminate consumption of marine fishes. The effects of cooking (boiling) on trace metal and proximate composition of silver pomfret fish were also investigated. Trace element results were determined by the Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometer wherein fish samples from both areas exceeded the standard limits set by FAO/WHO for manganese, lead, cadmiumm and chromium and boiling has no significant effects on these three metal concentrations. Long-term intake of these contaminated fish samples can pose a health risk to humans who consume them. 1. Introduction Fish is a healthy food for most of the world’s population particularly developing countries in contrast to meat, poultry, and eggs. Fish provides comparatively cheap and readily available protein sources (about 15 to 20 percent) in addition to long chains of n-3 fatty acids, amino acids, vitamins, and minerals which contributes to healthier nutritional options for a balance dietary intake [1, 2]. Among the all fishes, marine fish are very rich sources of protein and various mineral components. The total content of minerals in raw flesh of marine fish is in the range of 0.6–1.5% of wet weight [3]. Trace metals are present in water from natural sources such as the rocks of the sea bed and also accumulated as a result of human activities such as emissions from industrial processes. These elements are taken up by marine fishes which are higher up the food chain. As a result, the concentrations of many elements including mercury, arsenic, lead, and cadmium in fish can be relatively high compared to other foods. Many of these metals such as iron, copper, cobalt, manganese, molybdenum, nickel, and zinc are essential trace elements and play important roles in biological systems. Meanwhile, mercury, lead, and cadmium are toxic, even in trace amounts [4]. Moreover, elevated concentration of manganese and nickel has been found to be toxic to aquatic organism [5, 6]. To monitor trace metals concentrations in the coastal environment, marine fishes have been widely used as bioindicators due to their wide range of distribution. Several studies have been carried out on metal pollution in different species of edible fish. Predominantly, fish toxicological and environmental studies have prompted interest in the determination of toxic elements in seafood [7–10]. According to the

Abstract: Celiac Disease (CD) is an inherited, autoimmune disorder in which proteins from the grains wheat, rye and barley (collectively called gluten) damage the small intestine. The only treatment for CD is a strict, lifelong gluten-free diet. With a prevalence rate of about one in 100-133 people worldwide. Celiac disease is wide-spread across the globe. Unlike traditional allergies, which cause immediate reactions, gluten sensitivity is harder to pin down since it manifests gradually and in various forms like headaches, stomach cramps, bloating, anxiety, and depression. Due to complicated diagnosis procedure and lack of awareness, many cases are either misdiagnosed or not at all diagnosed in India and USA. In spite of high growth, gluten-free foods are facing problems to grain ground in Asian market, due to high price, lack of awareness about the products, large number of un-diagnosed cases and inefficient value chain for gluten-free products. One of the major issues in India and USA is very high prices of gluten-free foods as compared to regular food products. Globally, the market potential of gluten free products is estimated to be USD 4639.13 Million and USD 7594.43 Million in 2015 and 2020 respectively. The global gluten free food market is projected to grow with a CAGR between 9 percent and 10.2 percent during 2016-2022. The study on consumer preference of gluten-free foods would enable manufacturers of gluten-free foods to understand the current and evolving expectations of consumers and to design the products according. Study of two countries i.e., India and USA would enable manufacturers to understand the difference in choices and preferences related to gluten-free foods for both the nations. This study would help manufacturers of alternative wheat product to form the concrete marketing and product development strategy based on recent consumer behavior trends.

Journal of Textile Science and Technology (JTST) , 2015, DOI: 10.4236/jtst.2015.12008
Abstract: Today is the golden age of fashion. Fashion garments and apparels have been used everywhere to cope with the fashion era. These fashion garments and apparels are made of the fabrics of various structures and components through various processes. Among them gabardine is one of the most remarkable type of fabric and apparel dyeing is the latest process used for fashion apparel. From this research, the seam strength variations between dyed and un-dyed gabardine apparels after conceding the garment dyeing process can be known. It is a comparative research work which will deliver very effective knowledge about various types of seam, seam strength and seam performance. For comparative study, many dummy apparels body have been produced as samples which are dyed in Hams washing and dyeing limited. After that all samples have tested in Thermax woven dyeing laboratory. Since Bangladesh is a very potential fashion market and the fashion garments are being manufactured more and more. Hence the fashion trend is rapidly going to garments dyeing from conventional fabric/yarn dyeing processes. Gradually garments dyeing order are increasing higher to higher.
MicroRNAs: The Potential Biomarkers in Plant Stress Response  [PDF]
Sonali Bej, Jolly Basak
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.55089
Abstract:

MicroRNAs (miRNAs) are endogenous small RNA regulatory molecules of approximate 20-24 nucleotides that are involved in regulating the intrinsic growth and development of organs in plants and animals as well as in maintaining the integrity of genomes. Past few years have witnessed an increase in research reports on the crucial role of miRNAs in plant stress response. Plant miRNAs regulate gene expression at the post-transcriptional level not only by suppression of mRNA translation but also by direct cleavage of the target mRNAs. This review starts with a brief overview on small RNAs including miRNAs, biogenesis of miRNA and focuses mainly on the various up and down-regulated plant miRNAs under different biotic and abiotic stresses showing advancement of studies about miRNA and their stress regulation pathway. This review explores the emerging role of miRNAs as potential biomarkers in plant stress responses.

Mst. Shamsun Nahar, Jing Zhang
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.22024
Abstract: Recently, it has been report of polyvinyl chloride (PVC) shower hoses becoming hard and brittle throughout the eastern and middle portion of Shizuoka Prefecture, Japan. No reason has been identified for this phenomenon. The affected cities are located at the paper industries area. We have collected the stiffed hoses attached to shower faucets and examined them for chemical changes. In addition, we have analyzed the water quality of 11 affected cities in Shizuoka in an attempt to establish a probable bio-physico-chemical chain reaction that could cause such hose degradation. According to elemental analysis, oxygen-containing carbon-based plasticizers may leach out of the hose. As a result, the hoses lost flexibility after one year of use in Shizuoka. The organic nutrient (1,4-dioxane) was identified by GC-MS and the utmost number of the heterotrophic bacteria has been detected by PCR-DGGE in the shower water of Shizuoka. The study concludes that the plasticizer disappeared from the stiffed hose and the special characteristics of water in Shizuoka, consisting of organic nutrients, can be used for heterotrophic bacterial growth as a energy source at the shower water temperature, which allows prompt utilization of the plasticizer by increasing abundant bacteria, causing the brittleness of the PVC hose.

Abstract: Recently, there have been many reports of silicon rubber (SR) hoses becoming brittle in juice factory within one month of purchase. The damage is a new phenomenon, and its cause is unknown. We have collected the damaged hoses attached to UHT sterilizer (ultra-high-temperature) in juice factory and examined them for chemical changes. In addition, we have analyzed the hose-washing chemicals (NaOH and HNO333) and the exposure UTH temperature have direct effect on the brittleness of the silicon hose in juice factory.
Aggression in Boys and Girls as Related to Their Academic Achievement and Residential Background  [PDF]
Md Shahinoor Rahman, Lailun Nahar
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.45065
Abstract:

The study was conducted to explore aggression in boys and girls as related to their academic achievement and residential background in Bangladesh. Stratified random sampling technique was used and total 80 respondents constituted the sample of the study. They were equally divided into boys and girls. Each group was again equally divided into high and low grade. Each subgroup was again equally divided into urban and rural residential background. Thus the study used a 2 × 2 × 2 factorial design consisting of two levels of gender (boy/girl), two levels of academic achievement (high grade/low grade) and two levels of residential background (urban/rural). The Bengali version of measure of aggressive behavior (Rahman, A. K. M. R., 2003) originally developed by Buss and Perry (1992) was used for the collection of data. It was found that regardless of gender, boys expressed more aggression than girls. Similarly, regardless of academic achievement, students with high academic grade will show more aggressive behavior than low academic grade students. Finally, students of urban areas will not show significantly more aggressive behavior than rural areas students. Thus the differential treatment in gender, academic achievement and residential background provides a new dimension in understanding aggression in rural and urban boys and girls.

InSAR Observation for the Surface Displacements at Mt. Etna between 2003 and 2007  [PDF]
Syeda Sabikun Nahar, Arif Mahmud
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.62010
Abstract: This research is mainly devoted to InSAR observations using Poly-Interferogram Rate and Time-series Estimator (π-rate) software to investigate continuous surface displacement at Mt. Etna (Sicily), Italy between 2003 and 2007. Using ascending and descending SAR images produced by European Space Agency’s ENVISAT, we generate a set of interferograms which are used to determinethe deformation history of Etna from 2003 to 2007. Using (π-rate), we can generate the InSARtime-series and ratemap while minimizing errors induced by the satellites orbit and atmosphericphase delays. During the period of 2003-2007, three separate eruptions were observed. In order to explain the deformation, we solve three displacement rate for 2003-2005, 2006 and 2007. As expected, the result suggests that displacement rates are not constant with respect to time. During 2006 the volcano appeared to switch from a period of deflation to a period of inflation. These results highlight the importance of InSAR for generating deformation time-series around Mt.Etna, and with the application of numerical models these results can be used to estimate theamount of magma moving in the subsurface.
DEVELOPING CONCEPTUAL FRAMEWORK FOR REVISING LF-LEARNING MATERIALS (SLMs) OF THE OPEN SCHOOL (OS) OF BANGLADESH OPEN UNIVERSITY (BOU) AT A DIGITAL ENVIRONMENT
Sabina YEASMIN,CRK MURTHY
The Turkish Online Journal of Distance Education , 2011,
Abstract: uses the first generation self-learning materials (SLMs) written, before an era, following an in-house style and template. The concerned faculty member corrects, every year, texts before the reprint; but this is limited to spelling mistakes, factual errors and page make-ups only. The University has taken policy and steps to revise the texts as a whole which is still limited to the previous process. But; the current government is implementing the agenda of digital Bangladesh which definitely will influence the texts vis-à-vis template, learner’s instructions, gender-sensitiveness, context and content. In addition, education theory has been shifted from instructivism to constructivism which is being experimented and implemented by the Ministerial project entitled Teaching Quality Improvement (TQI) partnering with the BOU School of Education with new texts. Time changes, new things are being adopted. Open School also requires revising its texts in relation to the government’s current agenda of implementing the digital Bangladesh. This study collects data from tutors, distance educators, writers and reviewers and finally develops a framework for revising the OS SLMs at a digital environment.
