Fish Stupefying Plants Used by the Tribes of Nandurbar District.

The present paper deals with the identification of those plants which are used as natural toxins for capturing fishes from Nandurbar district of Maharashtra. Nandurbar district is tribal district, is rich in ethno biological diversity, its different tahasils have their own toxicant plants which can be used for capturing fishes. So this ethno biological survey was conducted in different tahasils of Nandurbar district viz Akkalkuwa, Dhadgaon, Shahada, Taloda, Nandurbar and Navapur. As fishes are the important source of protein for poor people living near the banks of rivers, they use few plants which are natural toxicants for fishes and capture the fishes. During this study, a number of toxicant plants are identified with the help of the people living near the river and dams. The general information related to vernacular name of the plant in different tahasil and plant parts used, have been identified by elders and knowledgeable people. Plants are identified taxonomically with the help of Botanist of Jijamata Education Society’s, Department of Botany For UG, PG and Research, Arts, Science and Commerce College, Nandurbar, Maharashtra. Extensive literature was also consulted for identification

EFFECT OF SHARPUNKHAMULACHURNA WITH TANDULODAK IN ASRUGDARA

Any abnormality in Rutuchakra (menstrual rhythm) leads excessive and irregular uterine bleeding which is known as “Asrugdara” in classical text. In routine practice of Striroga and Prasutitantra number of patients present with excessive and irregular bleeding vaginally. To study the effect of Sharpunkhamulachurna with Tandulodak in Asrugdara. Asrugdara gives rise to various systemic and psychological disorders which needs treatment. 30 patients were diagnosed with symptoms of Asrugdara attending OPD of our institute and fulfilling criteria are taken for the study. A special proforma was prepared with all points of history taking, physical signs and symptoms and lab. Investigations. The parameters were scored on the basis of standard methods of statistical analysis.In the study, Artavapraman shows 78.8% of relief, Rajastarvaavadhi shows 49.0% of relief, Daha shows 36.9% of relief, Adhoudarshula shows 59.2% of relief, interval between 2 cycle shows 0% of relief, consistency of bleeding shows 44.8% of relief, Varna shows 41.1% of relief and by wilcoxon test it is found that it is highly significant. So it can be concluded that efficacy of Sharpunkhamula churna is significant in Asrugdara on this symptom.Among the available treatment for Asrugdara, Sharpunkhamulachurna is beneficial in curing the vitiated Doshas. The treatment which includes Sharpunkhamulachurna which have been used based on their properties like Tikta and Kashayarasatmak which helps in Stambankarma, it is also Vatakaphaghna - all these objectives are fulfilled to the greater extent

Quantitative UV-spectrophotometry estimation of risperidone using hydrotropic solubilization phenomenon

The aim of present study was to develop simple and economical UV- pectrophotometric method for estimation of Risperidone using Area Under Curve (AUC) technique with the application of hydrotropic solubilisation phenomenon. Aqueous urea solution (30% v/v ) was used as hydrotropic agent for solubilising risperidone. The method is based upon integration of area under curve for analysis of risperidone in the wavelength range of 265.0 - 287.40 nm. The drug followed linearity in the concentration range of 4 - 24 g/mL with correlation coefficient value r 2 > 0.99. Proposed method was validated for accuracy, precision, repeatability and ruggedness as per ICH guidelines. The proposed method was applied for qualitative and quantitative estimation of risperidone in pharmaceutical formulation and results were found in good agreement with the label claimed. This developed method can be used for routine analysis of Risperidone in bulk and tablets

Highly Stable Cycling of Silicon-Nanographite Aerogel-Based Anode for Lithium-Ion Batteries

Silicon anodes are considered as promising electrode materials for next-generation high-capacity lithium-ion batteries (LIBs). However, the capacity fading due to the large volume changes (∼300%) of silicon particles during the charge−discharge cycles is still a bottleneck. The volume changes of silicon lead to a fracture of the silicon particles, resulting in the recurrent formation of a solid electrolyte interface (SEI) layer, leading to poor capacity retention and short cycle life. Nanometer-scaled silicon particles are the favorable anode material to reduce some of the problems related to the volume changes, but problems related to SEI layer formation still need to be addressed. Herein, we address these issues by developing a composite anode material comprising silicon nanoparticles and nano graphite. The method developed is simple, cost-efficient, and based on an aerogel process. The electrodes produced by this aerogel fabrication route formed a stable SEI layer and showed high specific capacity and improved cyclability even at high current rates. The capacity retentions were 92 and 72% of the initial specific capacity at the 171st and the 500th cycle, respectively

Silicon-Nanographite Aerogel-Based Anodes for High Performance Lithium Ion Batteries

To increase the energy storage density of lithium-ion batteries, silicon anodes have been explored due to their high capacity. One of the main challenges for silicon anodes are large volume variations during the lithiation processes. Recently, several high-performance schemes have been demonstrated with increased life cycles utilizing nanomaterials such as nanoparticles, nanowires, and thin films. However, a method that allows the large-scale production of silicon anodes remains to be demonstrated. Herein, we address this question by suggesting new scalable nanomaterial-based anodes. Si nanoparticles were grown on nanographite flakes by aerogel fabrication route from Si powder and nanographite mixture using polyvinyl alcohol (PVA). This silicon-nanographite aerogel electrode has stable specific capacity even at high current rates and exhibit good cyclic stability. The specific capacity is 455 mAh g−1 for 200th cycles with a coulombic efficiency of 97% at a current density 100 mA g−1
