MgB2 with Tc ≈ 40 K, is a record-breaking compound among the s-p metals and alloys. It appears that this material is a rare example of the two band electronic structures, which are weakly connected with each other. Experimental results clearly reveal that boron sub-lattice conduction band is mainly responsible for superconductivity in this simple compound. Experiments such as tunneling spectroscopy, specific heat measurements, and high resolution spectroscopy show that there are two superconducting gaps. Considering a canonical two band BCS Hamiltonian containing a Fermi Surface of π- and σ-bands and following Green’s function technique and equation of motion method, we have shown that MgB2 possess two superconducting gaps. It is also pointed out that the system admits a precursor phase of Cooper pair droplets that undergoes a phase locking transition at a critical temperature below the mean field solution. Study of specific heat and density of states is also presented. The agreement between theory and experimental results for specific heat is quite convincing. The paper is organized in five sections: Introduction, Model Hamiltonian, Physical properties, Numerical calculations, Discussion and conclusions.

Objective: To evaluate the etiology, clinical profile and outcome of acute abdomen presentation in Dengue Fever (DF). Methods: This clinical prospective study was done on confirmed cases of DF admitted in the department of medicine during recent epidemic (September 2015 to November 2016). All patients were evaluated clinically and by laboratory and imaging investigations and followed-up during hospital stay till discharge. The cause of pain abdomen was ascertained by blood tests (amylase, lipase and liver function test etc), radiology (Flat plate abdomen-erect, Ultrasonography of abdomen, CECT abdomen) and/or endoscopy. Results:Out of the 501 patients diagnosed as DF, 165 (32.93%) presented with acute abdomen. Some patients presented in other departments like surgery, gastroenterology and emergency, were later diagnosed as DF on laboratory evaluation. Various causes of acute abdomen in our study were nonspecific severe pain abdomen (67 cases), acute hepatitis (46) one had acute fulminant hepatitis, acute acalculous cholecystitis (31), ascitis (12), acute hyperemic gastritis with malena (5), acute pancreatitis (2), and 1 case each of acute appendicitis and acute jejuno-ileal intussuception. All patients were managed conservatively. One patient of acute pancreatitis died of multi-organ failure. Conclusion: Our study concludes that clinical vigilance about such type of presentations is important as timely recognition can influence outcome and may prevent unwanted surgery.

Background: Rabies is a dreaded disease and an estimated 55,000 people die of rabies every year. Himachal Pradesh is in the North bordering China and is predominantly rural and hilly. Villages are near forests, where wild reservoirs of rabies exist. Since health facilities are not accessible easily, we need to innovate on existing schedules of rabies vaccination keeping in view the compliance of the patients and affordability so as to give them the best possible option of treatment. In the year 2006 and 2007, we, at DDU Hospital Shimla, experienced a severe shortage of rabies vaccine and patients were running from pillar to post to fetch rabies vaccine. At the same time, we learnt that some of the patients died because either they were not able to purchase the vaccine, mostly because of its high cost, $35, or they ignored the animal bites and did not seek the treatment. Since last year, we have been experiencing non-availability of rabies immunoglobulins (RIGs) in the market and have to innovate new schedules and techniques to save lives of the patients. Methods: During shortage of rabies vaccine in 2008, we contemplated to start a low cost intra-dermal (ID) clinic so as to make rabies vaccine affordable as intramuscular (IM) vaccination cost five times more than ID vaccination. But, there were three main hurdles. One hurdle was the non-availability of rabies vaccine vials having written on them “For IM/ID use” and another hurdle was only fewer animal bite patients attending the DDU Hospital, sometimes only one or two per day, which was insufficient to open a vaccine vial and distribute among them. The third problem being faced was reluctance of the hospital doctors to prescribe ID vaccine as this was not the practice at higher teaching institutions, including medical colleges. We contacted a vaccine company and few vials labeled as “For IM/ID use” were sourced from Mumbai (1200 km away from here). We asked the Chief Medical Officer, Shimla district to write a lette

聚酯纤维是一种良好的服装用纤维,具有许多优点,然而由于它的吸湿性差,其美观性能下降。为改善这些性能,选择4种不同的100%聚酯织物试样,在等量的快速润湿剂、减量剂或两者组合的条件下,采用不同用量的NaOH和KOH对试样进行碱处理,并测试坯布织物试样的性能。结果表明:碱处理后,聚酯织物不仅单位长度的经纱和纬纱量减少,织物面密度下降,而且弯曲长度和弯曲刚度减小,但透气性有所提升。
