Problem statement: The South and South East Asian countries are characterized by their rich biodiversity as well as cultural diversity. Agricultural expansion for livelihood security is leading to an increase in pesticide application in this region. It has been observed that because of the hot and humid conditions prevalent in this region, most farmers and pesticide applicators do not use proper protective gear, thereby exposing themselves to the hazards of pesticide poisoning. Another important issue is the exposure of infants and children to toxic pesticides, especially in congested urban slums and tenements. Approach: The biodiversity contained in the six biodiversity hotspots located in this region was also at considerable risk from the toxic effects of pesticides from agricultural fields as well as plantations of tea, coffee, rubber, oil palm, which were often present in close proximity of protected areas. Though a large number of countries in this region had ratified and/or signed important international conventions on pesticide manufacture, export-import and trans boundary movements such as the Stockholm, the Rotterdam and the Basel conventions. Results: A large number of hazardous pesticides was still in use in this region and require to be phased out. Information was lacking on the use status of several pesticides in smaller countries, thereby retaining a certain amount of ambiguity. Conclusion: Despite the grave nature of the pesticide use regulation issue in the Asia-Pacific, clear and uniform policy response is lacking in most countries of this region. These issues need to be addressed through dialogues and mutual cooperation both at national as well as international levels. © 2012 Science Publications.

In the vertical longitudinal plane of a tractor, the three-point hitch system is a six-bar mechanism that can be designed and modelled as two distinct four-bar linkages sharing two links. A Newton-Raphson solution for the four-bar linkage has been applied to a three-point hitch system of tractor to determine the range of movement of the lift arm and generate the path of motion of lower and upper hitch points in the movement range of the hitch. The algorithm was executed as a program in MATLAB. The program has the ability to generate the path of motion of lower; upper and virtual hitch points, determine the geometric performance parameters of the hitch system, and identify the variations in the quality of force transmission by the linkage system throughout the range of hitch movements for 165 different groups of hitch dimensions available in the Nebraska tractor test reports. Application of the program for searching improved design solutions for the existing hitch system of a tractor was demonstrated. The program has the potential to be used in any search-based techniques for optimisation of the dimensions of three-point hitch systems for tractors. In addition, variations in length of links and spatial location of their pivot points were studied for various categories of hitches. The range of values of link lengths and the spatial location of their pivot points reported here can be used for defining the design space during the optimal dimensional synthesis of tractor three-point hitch systems. © 2012 IAgrE.

Background: Undernutrition is a major public health concern in many of the developing countries of Asia. Due to immense population size, socioeconomic disparities, illiteracy and inadequate access to health facilities prevalence is very high in India. The objective of this study was to determine the prevalence of age-sex specific thinness (low BMI-for-age) among adolescents residing in rural regions in India. Materials and Methods: This cross-sectional study has conducted among 1165 adolescent (602 boys; 563 girls) aged 10-18 years of Darjeeling district, West Bengal, India. Anthropometric measurements were height and weight obtained and BMI (weight/height2, kg/ m2) was calculated. The prevalence of thinness was assessed using newly proposed age-sex specific cut-offs of Cole et al. The data were analyzed using chi-square, ANOVA and Least Mean and Square (L,M and S) model approach. Results: Prevalence of overall thinness is 49.10% (51.16% boys, 46.89% girls) among rural adolescents. The boys are found to be more sufferer than girls in the different thinness grades include mild (grade I; 27.41% vs. 27.11%), moderate (grade II; 14.62% vs. 12.08%) and severe (grade III; 9.14% vs. 8.70%) (p>0.05). The age and sex specific smooth percentile curves of BMI were derived using L,M and S model approach for further evaluation of nutritional status. Conclusion: The existence of high prevalence of thinness among adolescents indicates nutritional deprivation among rural Indian adolescents. There is an urgent need of appropriate nutritional intervention program to address the public health problem related to undernutrition especially among nutritionally vulnerable segments of adolescents residing in rural regions to ameliorate the nutritional status.

Nanocellulose is an emerging sustainable biomaterial with exceptional physicochemical properties. It can be isolated from inexpensive renewable cellulosic biomass and a number of natural plant fibers have been extensively investigated as a source for such isolation. The geometrical dimensions of the prepared cellulose nanocrystals (CNCs) are however, found to vary widely, depending on the source of the cellulosic material and hydrolysis conditions. CNCs are biocompatible and biodegradable which exhibit very low cytotoxicity thus, offering a wide range of opportunities for biomedical applications. By surface modification of nanocellulose, various functional materials with tunable properties can also be developed. Over the past two decades, CNCs have garnered a significant interest as biobased reinforcing nanofiller material. This mini review will provide an overview into the production methods, sources of cellulosic fibers, surface modification strategies and drug delivery applications of the chemically or mechanically isolated nanocellulose. © 2015 Bentham Science Publishers.

Northeast India has one of the world's highest incidences of oral cancer and 90% of them are related to tobacco. We examined the complete mitochondrial genome to determine hot spot mutations in oral cancer. The complete mitochondrial genome was sequenced using PGM™ from 10 patients matched blood and tumour tissue. Overall, 26 somatic mutations were found of which nine mutations in d-loop and 17 mutations in the coding region. The mutations at nucleotide positions 16294, 16325 and 16463 in d-loop and 4136, 13542 and 13869 in coding region are probably an indication to be a hot spot mutation in oral cancer. The knowledge about role, patterns and timing of mitochondrial mutations may serve to be facilitating clinical applications and hot spot mutations may be helpful in assessing cancer risk in tumour. © 2013 Informa UK, Ltd.

In a multi server queuing system, buffer size is often larger than the number of servers. This necessitates queuing and waiting for some customers. Customers become impatient while waiting for service. Additionally, they may also become impatient if service is not offered at the desired rate. This paper analyses a finite buffer multi server queuing system with the additional restriction that customers may balk as well as renege. Closed form expressions of a number of performance measures are presented. A design problem is discussed to demonstrate the results derived. © 2012 EDP Sciences, ROADEF, SMAI.

A comparative study has been made on the synthetic strategy, particle morphology and surface charge of the aqueous dispersion gold nanoparticles stabilized electrostatically by 4-(dimethylamino)pyridine (DMAP) and trisodium citrate. The information from UV-vis spectroscopy, transmission electron microscopy and zeta potential measurements substantiated the result. To explore the real-time applications of these two interesting systems, solubility and stability of these two types of stabilized particles and the nature and extent of the interaction of the stabilizing ligand shell with the surface of gold nanoparticles have been elucidated. The size regime dependence of the citrate-stabilized particles has been rationalized in view of the dependence of surface area on the size of the particles. © 2010 Elsevier B.V.

Bimaximal (BM) and tri-bimaximal (TB) mixings of neutrinos are two special cases of lepton mixing matrix, which predict the reactor angle θ 13=0 and the atmospheric angle tan 2θ 23=1. Recent precision measurements and global analysis of oscillation parameters, have confirmed a non-vanishing value of θ 13 as well as deviations of θ 12 and θ 23 from their maximal values predicted by BM or TB mixing. In this work we mainly concentrate on θ 13 and θ 23 to assign θ 13≠0 and tan 2θ 23<1 with the help of charged lepton corrections defined by UPMNS=Ul†Uν. We first consider U ν to be given separately by BM and TB mixing matrices and then find the possible forms of U l such that the elements of PMNS matrix, finally yield θ 13≠0 and tan 2θ 23<1 in agreement with latest observational data. To compute the values of mixing angles we assume the charged lepton correction to be of Cabibbo-Kobayashi-Maskawa (CKM) like. All the mixing matrices involved in the calculation satisfy the unitarity condition to leading order of expansion parameter. We also analyze both the mixing schemes in presence of Dirac CP phase and find expressions for the rephasing invariant quantity J CP which have been discussed in recent literature. © 2012 Elsevier B.V.

Hydrophobic photoluminescent carbon nanodots (CNDs) were fabricated by using citric acid and L-tyrosine precursor molecules through a simple, facile thermal oxidation process in air. These CNDs (less than 4 nm in size) exhibited a characteristic excitation wavelength dependent emission and upconversion emission properties and are insoluble in water, but soluble in organic solvents. FTIR and 1H NMR analyses showed a selective participation of L-tyrosine molecule during the carbonization process at 220 oC without a disturbance of its benzylic protons and aromatic phenyl ring bearing hydroxy group. TEM and XRD studies revealed a quasi-spherical morphology and poor-crystalline nature of CNDs. Because the presence of the hydroxy group of L-tyrosine is dominating at the surface, these CNDs are also soluble in water under basic conditions. The effects of base and silver nanoparticles on the luminescence properties of CNDs were studied and a quenching of fluorescence was observed. These tyrosine-passivated CNDs are applicable for both biologically and commercially. © 2014 Gude.
