The present study was undertaken in a moist deciduous forest of Indo-Gangetic plain to assess the species structure, population abundance and distribution pattern, regeneration status, diversity and dominance. Three sites selected on the basis of the disturbance gradient showed sequential differences in analytic characters. Population density decreased from 82 ha-1 from site I to 486 ha-1 in site III, where as basal area enhanced from 6.8 m2 ha-1 to 62.2 m2 ha-1 correspondingly. Diversity index and species richness were highest for inner undisturbed site III. Distribution pattern of various growth forms showed mostly the contagious distribution. Population structure of common trees showed poor regeneration and a nonlinear reduction in girth distribution pattern with increasing diameter classes. Mostly forage grasses were found in open forest (site I) whereas ground flora mainly consisted of medicinal herbs in the undisturbed dense forest (site III).Keywords

The chief protein of the seeds of Terminalia belerica and Duabanga sonneratioides is globular in nature. The seeds of Cassia tara are rich in both albumins and globulins. The proteins have been analysed for their Van Slyke nitrogen distribution and tyrosine and tryptophane contents. The Terminalia belerica and Cassia tora globulins while comparing favourably with the globulins of Santalam album, are rather poor in tryptophane content as compared with Dolichosin but are superior to Cajanin. The Duabanga sonneratioides globulin is poor in cystine also. The albumins from Terminalia belerica and Cassia tora are essentially inferior to the albumin from Cajanus indicus in their cystine contents.- Extubation Outcome after Spontaneous Breathing Trials with T-tube or Pressure Support Ventilation

A 2-h T-tube trial of spontaneous breathing was used in selecting patients ready for extubation and discontinuation of mechanical ventilation. However, some doubt remains as to whether it is the most appropriate method of performing a spontaneous breathing trial. We carried out a prospective, randomized, study involving patients who had received mechanical ventilation for more than 48 h and who were considered by their physicians to be ready for weaning according to clinical criteria and standard weaning parameters. Patients were randomly assigned to undergo a 2-h trial of spontaneous breathing in one of two ways: with a T-tube system or with pressure support ventilation of 7 cm H2O. If a patient had signs of poor tolerance at any time during the trial, mechanical ventilation was reinstituted. Patients without these features at the end of the trial were extubated. Of the 20 patients assigned to the T-tube group, 15 successfully completed the trial and were extubated; 5 of them required reintubation. Of the 20 patients in the group receiving pressure support venti¬lation, 17 were extubated and 3 of them required reintubation. The percentage of patients failing the trial and ICU mortality was significantly higher when the T-tube was used. Clinical evolution during the trial was not different in patients reintubated and successfully extubated. Spontaneous breathing trials with pressure support or T-tube are suitable methods for successful dis¬continuation of ventilator support in patients without problems to resume spontaneous breathing.Keywords

Gas Tungsten Arc Welding (GTAW) uses a non-consumable tungsten electrode to produce the weld joint. The properties of the welded joints are affected by a large number of welding input parameter such as welding current waveform, welding current, welding speed and gas flow rate, these parameters plays a very significant role in determining the quality of a weld joint. In this work butt weld joint of Copper and Stainless Steel (SS304) is obtained by using autogenous GTAW process. The trial runs had been conducted to find out optimum range of process parameters. Four parameters such as welding current, welding speed, welding torch angle and gas flow rate are considered. The effect of these parameters on mechanical properties such as tensile strength, impact strength, bend strength and hardness of weld joint is analyzed.Keywords

This study aimed to assess the impacts of ultraviolet-B (UV-B) radiation over a 28-day period on the levels of pigments of Umbilicaria aprina and Bryum argenteum growing in field. The depletion of stratospheric ozone is most prominent over Antarctica, which receives more UV‑B radiation than most other parts of the planet. Although UV‑B radiation adversely affects all flora, Antarctic plants are better equipped to survive the damaging effects of UV‑B owing to defenses provided by UV‑B absorbing compounds and other screening pigments. The UV-B radiations and daily average ozone values were measured by sun photometer and the photosynthetic pigments were analyzed by the standard spectrophotometric methods of exposed and unexposed selected plants. The daily average atmospheric ozone values were recorded from 5 January to 2 February 2008. The maximum daily average for ozone (310.7 Dobson Units (DU)) was recorded on 10 January 2008. On that day, average UV‑B spectral irradiances were 0.016, 0.071, and 0.186 W m −2 at wavelengths of 305, 312, and 320 nm, respectively. The minimum daily average ozone value (278.6 DU) was recorded on 31 January 2008. On that day, average UV‑B spectral irradiances were 0.018, 0.085, and 0.210 W m −2 at wavelengths of 305, 312, and 320 nm, respectively. Our results concludes that following prolonged UV-B exposure, total chlorophyll levels decreased gradually in both species, whereas levels of UV-B absorbing compounds, phenolics, and carotenoids gradually increased.Keywords

This study presents scientometric analysis and network visualization of journal articles on Nipah virus for a better understanding of research trends on the subject. Metadata of journal articles were retrieved from Scopus database in 2018. After filtration of irrelevant and incomplete records, 1007 records were analysed to examine the publishing trends on Nipah virus. The network visualization was accomplished using ‘VOSviewer’, ‘Gephi’ and ‘Sciencescape’ software. Results revealed inconsistent growth of articles on the subject. There were only few productive authors with ≥ 15 records, but others contributed on the subject occasionally. The United States (as a country) and North America (as continent) led the world in terms of contribution to the number of articles (n = 469 and 522 records respectively). Six leading institutes contributed to ≥50 records each. Out of 373 journals, ten core journals published 31% of the total journal articles. Predominant topics discussed in the articles included: characterization, pathogenesis, clinical symptoms, transmission, outbreaks and vaccine development. A great degree of inter-country and inter-continent collaboration was detected among the US, Australia, Malaysia, United Kingdom and Bangladesh, depicting that the developed world is working in association with the developing nations to tackle the problem.Keywords
