We report the electrical studies of nanocomposites of Multiwalled Carbon Nanotubes (MWCNTs) and Poly(vinylidene fluoride) (PVDF).The MWCNTs were synthesized by chemical vapour deposition (CVD) method. Solvent evaporation method is used to prepare MWCNT-PVDF composite films. Scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) were used to study structure and morphology of the composites. The temperature dependant conductivity measurements for the nanocomposites were performedusing the well established four probe method. Source

A number of emergency situations require immediate drug administration for reducing the morbidity and mortality. Autoinjectors are very useful devices for the rapid administration of the recommended drugs. They are well suited for emergency and mass casualty management, convenient to use and fast in action. A variety of autoinjectors are available viz., for nerve agent poisoning (atropine sulphate and pralidoxime chloride), anaphylactic shock (epinephrine), seizures (diazepam), and migraine (sumatriptan). The advantages of these autoinjectors are reviewed here with a focus on the requirement for autoinjectors for an antibacterial and an analgesic drug. © 2012, DESIDOC. Source

Oral leukoplakia is one of the common potentially malignant disorder which is mostly associated with the use of tobacco either in the form of smoking or smokeless, though idiopathic leukoplakia in patients free from habits has also been reported. Diagnosis of the lesion in most of the cases is mainly based on history of use of tobacco and clinical finding such as raised elevated non-scrap able white patch seen in oral mucosa. Oral leukoplakia once diagnosed, the patient is advised to discontinue the habit after proper counselling of the risk of leukoplakia turning into malignancy and is supported with mainly antioxidants in mild cases. There are few clinical trials using other non surgical management like topical bleomycin, laser therapy, photodynamic therapy etc., but use of antioxidants is more common. This review article aims in evaluating all the clinical trials using antioxidants namely Vitamin A, E, C, and lycopene as they are the most commonly used antioxidants in treatment of oral leukoplakia to assess the outcome measures such as clinical resolution, adverse effects, recurrence and malignant transformation.

Glass fibre-reinforced polymer (GFRP) composites are alternative to engineering materials because of economic, light weight, corrosive resistance and superior properties. The experimental research under taken by the scholars is to study the impact of machining parameters on surface roughness of composite material by applying artificial neural network (ANN) and response surface method (RSM). The orthogonal turning operations were carried out on the composite material using tungsten carbide (WC) insert. During machining, the cutting speed (Vc), feed rate (fs) and depth of cut (a p) were varied. Turning experiments were designed based on the statistical three level full factorial experimental design techniques. An artificial neural network and response surface method have been developed, which can predict the surface roughness of the machined workpiece. The experimental results concur well with the results obtained from predictive model. © 2012 Praise Worthy Prize S.r.l. - All right reserved. Source

Background: Teaching basic science courses is challenging in undergraduate medical education because of the ubiquitous use of didactic lectures and reward for recall of factual information during examinations. The purpose of this study is to introduce concept maps with clinical cases (the innovative program) to improve learning of biochemistry course content. Methods: Participants were first year medical students (n=150) from Saveetha Medical College and Hospital (India); they were randomly divided into two groups of 75, one group attending the traditional program, the other the innovative program. Student performance was measured using three written knowledge tests (each with a maximum score of 20). The students also evaluated the relevance of the learning process using a 12-item questionnaire. Results: Students in the innovative program using concept mapping outperformed those in the traditional didactic program (means of 7.13-8.28 vs. 12.33-13.93, p<0.001). The students gave high positive ratings for the innovative course (93-100% agreement). Conclusion: The new concept-mapping program resulted in higher academic performance compared to the traditional course and was perceived favorably by the students. They especially valued the use of concept mapping as learning tools to foster the relevance of biochemistry to clinical practice, and to enhance their reasoning and learning skills, as well as their deeper understanding for biochemistry. © 2013 Krishna M.
