Through a questionnaire based survey, newspaper reading habits of the graduate students of Social Science faculty of University of Rajshahi in Bangladesh has been studied.The study demonstrates that majority of the graduate students read Bengali and English newspapers. Moreover, the research reveals that international section of the newspaper is the mostly preferred section. This paper also highlights that a majority portion of respondents prefer hall library to read printed newspaper while a large number of them prefer computer center of the university central library to read online newspapers. The study also highlights the barriers and attempts to provide the suggestions to overcome the hurdles of reading both printed and online newspapers.

Himachal Pradesh, a state with diverse culture and tradition is located between 30o22'40'' north latitudes and 75o45'55'' to 79o04'20'' east longitude. The state revealed a wide range of uniqueness and variability in traditional fermented foods made of cereal, pulses and milk. Most of these items are prepared by boiling, smoking, roasting, frying and fermentation. These food items are explored for their biochemical analysis and microbial profile and main nutritional aspects. Biochemical analysis of these food items showed an acidic nature with pH in the range of 3.25-4.20. Total soluble solids were in the range of 8oB-16oB. Microbial examination of these food items, their morphological and biochemical identification and 16S rRNA of some of important microorganisms revealed the presence of Lactobacillus, Bacillus and yeast species predominantly.

In this paper, approximated solutions for some non linear problems are calculated by the Adomian Decomposition Method (ADM) and Homotopy Perturbation Method (HPM) and then the results are compared. The fact that the Homotopy Perturbation Method (HPM) solves nonlinear problems without using Adomian’s polynomials is a clear advantage of this technique over the Adomian Decomposition Method (ADM).

Phytochemical constituents are responsible for medicinal activity of plant species. Hence in the present study preliminary phytochemical screening of Ceropegia pusilla a medicinal plant was carried out. Qualitative phytochemical analysis of these plants confirm the presence of various secondary metabolites like saponins, triterpenoids, steroids, tannins, lignins, alkaloids, glycosides, flavonoids and phenols. The results suggest that the phytochemical properties for curing various ailments and possess potential anti-inflammatory, antimicrobial and antioxidant and leads to the isolation of new and novel compounds. GC-MS analysis showed the existence of various compounds with different chemical structures. The presence of various bioactive compounds confirms the application of Ceropegia pusilla for various ailments by traditional practitioners. However, isolation of individual phytochemical constituents may proceed to find a novel drug.

The antimicrobial activity of Ayurvedic medicine (Draksharishta, Kanakasava, Jierbadyarishta) and Unani medicine (Alvasin and Carmina syrup) against different microbes (Staphylococcus sp., Escherichia coli, Klebsiella sp., Salmonella typhi, Bacillus subtilis, Proteus sp., Enterococcus sp., Acinetobacter sp.) were investigated using the agar well method. Ayurvedic medicine were showed more effective antimicrobial activity than unani medicine. In case of Ayurvedic, Jierbadyarishta showed 15mm zone of inhibition against Proteus sp., Enterococcus sp., Acinetobacter sp., Staphylococcus sp., Klebsiella sp. and 10mm zone of inhibition was observed against Salmonella typhi, Bacillus subtilis and Escherichia coli. On the other hand, Draksharishta showed 15mm zone of inhibition against Staphylococcus sp., Klebsiella sp., Salmonella typhi, Bacillus subtilis, Enterococcus sp., Acinetobacter sp. whereas 17.5mm and 10mm zone of inhibition were found against Proteus sp., and Escherichia coli respectively. Kanakasava showed 17.5 mm zone of inhibition against Proteus sp., Enterococcus sp. In all the cases, commercial antibiotic showed less antimicrobial activity than Ayurvedic medicine against all the test organisms. All of Ayurvedic medicine showed the MIC values ranged from 1-100 µl/ml while the MBC values ranged from 0.1-10 µl/ml. This study is an indication that the test Ayurvedic medicine is more challengeable than the test Unani medicine.

The present study is an account of the karyotypic analysis carried out in a three and half year old male child born to a young, healthy, non-consanguineous couple. Clinically the child had undescended testes (Cryptorchidism) with empty scrotal sac. It was an uneventful, full term delivery with no family history of congenital anomalies. Besides cryptorchidism, the child had developmental delay as well as mental retardation. Chromosome study was carried out to rule out the chromosomal cause, if any in the child having gross phenotypic anomalies. The karyotype of the child was found to be 49, XXXYY.

This mathematical model has been presented to study the effect of a stenosis shape on arterial blood flow characteristics with the representation of blood by Bingham plastic fluid model. The governing equations of proposed model are solved and closed form expressions for the blood flow characteristics, namely dimensionless resistance to flow, flow rate and wall shear stress are derived. It has been found that the wall shear stress and resistance to flow increase with increasing tube radius for constant value of the stenosis height, while decreases as stenosis shape parameter increases.

Reneging involves the phenomenon of customers joining a queuing system but departing without completely receiving service. There are situations where customers begin receiving service but disengage before service completion. Emergency patients attended by critical care professionals are of such type. This paper deals with the analysis of Markovian finite buffer queuing system without any waiting space under the assumption that customers may disengage i.e. renege before the completion of service. Explicit results for this model are presented. A few fresh performance measures have been suggested. A numerical example with design implications rounds up the paper.

Chickpea is the premier pulse crop of India grown on about 8.25 million ha. area with a production of 7.05 million tones, which accounts for 75% of the world chickpea production. In Karnataka, the area under chickpea is around 6.50 lakh ha. with a production of 3.1 lakh tonnes at an average productivity of 620kg/ha. However, the overall production and productivity of the country is much lower than the other countries. The success of chickpea improvement programme largely depends on the wealth of the genetic resources and are the most valuable and essential basic raw material to meet the current and future needs in chickpea crop improvement programme. The present investigation consisted of one hundred and seventy nine chickpea genotypes were evaluated for genetic variability in qualitative and quantitative traits of economic importance in simple lattice design with two replications. Analysis of data revealed that the genotypes exhibited highly significant differences for days to 50 % flowering, plant height (cm), number of primary branches, number of pods per plant, days to maturity, 100 seed weight (g), harvest index and grain yield per plant(g). A considerable variation between genotypes for qualitative traits such as early plant vigour, growth habit, seed colour, seed shape and testa texture was also recorded. The grain yield showed highly significant positive association with number of pods per plant, harvest index, number of primary branches, plant height, and number of seeds per pod at phenotypic level. However, days to maturity was negatively correlated with grain yield. Genetic variability for plant height, number of primary branches, number of pods per plant and 100 seed weight respectively ranged from 23.2–49.6 cm, 1.8–5.6, 12.4–66.4 and 9.0–30.0. Whereas grain yield per plant varied from 1.7–30.0g, and harvest index ranged from 0.02–0.46 while the variation for days to flowering was in the range of 44.0–76.0 and 89.0–114.0 for days to maturity. The variation revealed in this study would be exploited in breeding programs aimed at development of high yielding genotypes.
