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
Isolation of Pectinase Producing Bacteria from the Rhizosphere of Andrographis paniculata Nees and 16S rRNA Gene Sequence Comparison of Some Potential Strains  [PDF]

Abstract: Pectinases, the enzymes which break down pectic substances, have a wide range of applications in food, agriculture and environmental sectors. In the present study, attempts were made to isolate highly efficient pectinase producer from the rhizosphere of a medicinal plant, Andrographis paniculata Nees, known as the “King of bitters”. The total heterotrophic bacterial count of the rhizosphere soil of A. paniculata Nees ranged from 1.53 × 109 to 2.52 × 109 cfu/g. A total of 65 bacterial colonies were randomly selected from the nutrient agar plates, purified and assessed for pectinase activity. Out of the 65 isolates, 62 (95.38%) showed varying degree of pectinase activity in plate assay using pectin as a sole source of carbon. Among the pectinase producing strains, JBST36 showed best pectinase activity which is followed by the JBST22 and JBST27. Morphological characterization, biochemical tests and 16S rRNA gene sequencing were performed to identify the three most potential strains. Based on the morphological, biochemical and molecular data, JBST22 was identified as Bacillus flexus and the other two were identified as Bacillus subtilis. Furthermore, nucleotide sequences of the 16S rRNA gene of these 3 strains were compared and a phylogenetic tree was constructed. The study reveals that there are at least 66 base differences in the 16S rRNA gene sequences of B. flexus JBST22 and the B. subtilis JBST36.
Effect of probiotics on broiler meat quality

African Journal of Biotechnology , 2009,
Abstract: The study was carried out on “Hubbard Isa Starbo” broilers to evaluate the raw meat quality of both probiotics and conventional fed broilers in pre-freezing condition and post freezing storage. 80 day old broiler chicks were divided into 4 groups of equal numbers as group A (probitotics fed group vaccinated), B (probiotics fed group nonvaccinated), C (conventional fed group vaccinated) and D (conventional fed group nonvaccinated). The groups C and D were taken as control birds and were fed with commercial ration and the groups A and B as experimental birds which were fed with commercial ration plus 2 g probiotics (Protexin Boost)/10 L drinking water up to 6th week of age. At the end of the 6 week feeding trial, the birds were slaughtered and dressed and subjected to organoleptic examination at 0, 7, 14 and 21 days of frozen storage. The increased panel scores were substantially obtained by all absorbent paper (AP) packed meat samples of probiotics fed group as compared to aluminium foil (AF) packed samples kept at frozen storage for 7, 14 and 21 days. The presence of high number of pathogenic Staphylococci and Escherichia coli encountered in meat from conventional fed broilers is alarming. The presence of these organisms in meat foods should receive particular attention, because their presence indicate public health hazard and give warning signal for the possible occurrence of food borne intoxication. The results of the study evidenced that supplementation of probiotics in broiler ration improved the meat quality both in prefreezing and postfreezing storage.

Similarity Matching Techniques For Fault Diagnosis In Automotive Infotainment Electronics
Mashud Kabir
International Journal of Computer Science Issues , 2009,
Abstract: Fault diagnosis has become a very important area of research during the last decade due to the advancement of mechanical and electrical systems in industries. The automobile is a crucial field where fault diagnosis is given a special attention. Due to the increasing complexity and newly added features in vehicles, a comprehensive study has to be performed in order to achieve an appropriate diagnosis model. A diagnosis system is capable of identifying the faults of a system by investigating the observable effects (or symptoms). The system categorizes the fault into a diagnosis class and identifies a probable cause based on the supplied fault symptoms. Fault categorization and identification are done using similarity matching techniques. The development of diagnosis classes is done by making use of previous experience, knowledge or information within an application area. The necessary information used may come from several sources of knowledge, such as from system analysis. In this paper similarity matching techniques for fault diagnosis in automotive infotainment applications are discussed.
Investigation of the Central and Peripheral Analgesic and Anti-inflammatory Activity of Kutajarishta, an Indian Ayurvedic formulation
Ashraful Kabir
International Journal of Phytopharmacy , 2012, DOI: 10.7439/ijpp.v2i5.746
Abstract: Kutajarishta (KTJ) is an Ayurvedic formulation approved by the “National formulary of Ayurvedic Medicine 2011”, of Bangladesh. It is widely available in the Bangladeshi market as an effective preparation to treat lumbago, sciatia and arthritic pain of joints. Our present studies make an attempt toward identifying probable anti-nociceptive and anti-inflammatory mechanisms of KTJ. KTJ, at three doses, (10mL/kg, 20mL/kg, and 40mL/kg) showed no involvement of the CNS in anti-nociceptive activity of KTJ. Carrageenan induced paw edema and acetic acid writhing tests both gave significant results (P ≤ 0.05), indicating possible peripheral analgesic and anti-inflammatory action. Formalin induced paw-licking test showed that KTJ had significant effect in suppressing inflammatory pain (P≤0.05) but not neurogenic pain. Hence our study shows anti-inflammatory and peripheral analgesic action for KTJ.

Fragment Formation in Biased Random Walks
Kabir Ramola
Statistics , 2008, DOI: 10.1088/1742-5468/2008/10/P10002
Abstract: We analyse a biased random walk on a 1D lattice with unequal step lengths. Such a walk was recently shown to undergo a phase transition from a state containing a single connected cluster of visited sites to one with several clusters of visited sites (fragments) separated by unvisited sites at a critical probability p_c, [PRL 99, 180602 (2007)]. The behaviour of rho(l), the probability of formation of fragments of length l is analysed. An exact expression for the generating function of rho(l) at the critical point is derived. We prove that the asymptotic behaviour is of the form rho(l) ~ 3/[l(log l)^2].

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2013, DOI: 10.4236/ijcns.2013.61002
Abstract:

The existence of various geo-location applications and their accuracy requirements enhance the necessities for suitable processing techniques to solve the indoor geo-location problems. Since, Impulse Radio Ultra-Wideband (IR-UWB) signals have very short duration pulses; they can provide very accurate ranging and geo-location capability in short range indoor radio propagation environments. Our research puts emphasis on indoor geo-location using UWB signaling considering both of non line-of-sight (NLOS) and LOS radio propagation environments. In this paper, we introduce and investigate a noble approach which makes a hybrid combination of Channel Impulse Response (CIR)-based finger-printing (FP) method with polygonal arrangement of reference nodes (or tags) and an iterative-TOA based real-time geo-location method using UWB signaling for wireless ad hoc networks. The proposed hybrid approach assures significant improvement in positioning accuracy compared to TOA only, FP only and conventional iterative-TOA geo-location methods by mitigating NLOS errors effectively in the indoor environment. Besides, this hybrid approach minimizes the calculation complexity of the FP method while maintaining improved geo-location accuracy in the dense multipath propagation environment.
