Structural, optical and nanomechanical properties of (1 1 1) oriented nanocrystalline ZnTe thin films

Structural, optical and nanomechanical properties of nanocrystalline Zinc Telluride (ZnTe) films of thickness upto 10 microns deposited at room temperature on borosilicate glass substrates are reported. X-ray diffraction patterns reveal that the films were preferentially oriented along the (1 1 1) direction. The maximum refractive index of the films was 2.74 at a wavelength of 2000 nm. The optical band gap showed strong thickness dependence. The average film hardness and Young’s modulus obtained from loaddisplacement curves and analyzed by Oliver-Pharr method were 4 and 70 GPa respectively. Hardness of (1 1 1) oriented ZnTe thin films exhibited almost 5 times higher value than bulk. The studies show clearly that the hardness increases with decreasing indentation size, for indents between 30 and 300 nm in depth indicating the existence of indentation size effect. The coefficient of friction for these films as obtained from the nanoscratch test was ∼0.4.Financial support in the form of fellowships to MSRNK and SK from the ACRHEM project of DRDO is acknowledged

Analyzing Public Sentiments: A Review

Large number of users share their opinions on Social networking sites. it can be useful for analyzing sentiments of different peoples about different domains/products. so that this analysis can be beneficial for making various decisions in various fields. For instance a company can analyze sentiments about products while a politician can view comments about them to improve their position in the society. in previous studies only track of sentiments can be taken but in this we are trying to analyze the public sentiments and trying to find out the possible reasons behind variation about comments based on that we tries to propose a system and tries to improve performance of system.

Development of a high resolution daily gridded temperature data set (1969-2005) for the Indian region

A high resolution daily gridded temperature data set for the Indian region was developed using temperature data of 395 quality controlled stations for the period 1969–2005. A modified version of the Shepard's angular distance weighting algorithm was used for interpolating the station temperature data into 1° latitude × 1° longitude grids. Using the cross validation, errors were estimated and found less than 0.5 °C. The data set was also compared with another high resolution data set and found comparable. Mean frequency of cold and heat waves, temperature anomalies associated with the monsoon breaks have been presented

Rare case of huge rectal and uterovaginal prol

A case of combined genital prolapse and rectal prolapse in a 60-year-old multipara is reported. The treatment of mixed prolapse remains surgical and should be treated the genital prolapse by vaginal hysterectomy with pelvic floor repair and the rectal prolapse by means of the Delorme operation. The mortality and morbidity rates are zero if this operation is used and the relapse rate is only 8 to 11% for the rectal prolapse. It would appear that the two approaches are rarely associated by the authors and would seem to be interesting to reconsider this question by indicating mixed treatment of the two prolapses whenever possible

Effect of a missing observation on Hotelling's generalized T02

A generalization of the missing plot technique in univariate linear models to the multivariate case is given in this paper. The estimate of the missing observation vector produces the correct error matrix and the correct parameter estimates but the hypothesis matrix is biased. The adjustment required to the test, for achieving the desired level of significance, when the biased hypothesis matrix is used, is derived.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27904/1/0000324.pd

A nanocrystal technology: to enhance solubility of poorly water soluble drugs

Most of the recently developed new chemical entities are poorly water soluble and they create major problems during formulation and development of new dosage form and due to poor solubility and poor bioavailability. The drugs belong to BCS class II and class IV has problem of solubility, to overcome the solubility problem nanotechnology is most useful technique. In this review article the main focus on Nanocrystals and various techniques used for preparation of Nanocrystals. Drug nanocrystals consists pure poorly water soluble drugs without any matrix material which means that it is carrier free drug delivery. Nanocrystals technologies have been introduced as advantageous, universal formulation approaches for the BCS class II and IV drugs. Nanocrystals, with greater surface to volume ratio, can effectively increase both the dissolution rate and saturation solubility of active ingredients The Nanocrystals is suitable drug delivery system for all commonly used routes of administration such as oral, IV, SC, and IM and topical application. Nanocrystals can also be incorporated into the tablets, capsules, fast-melts and lyophilized for sterile product applications. There are no of techniques which are used for production including precipitation, milling, high pressure homogenization and combination methods such as Nano-Edge, SmartCrystal and Precipitation-lyophilization-homogenization (PLH) technology

Study of prevalence and determinants of polycystic ovarian syndrome among adolescent girls in rural area: a prospective study

Background: Polycystic ovarian syndrome (PCOS) is the most frequent endocrinological disorder affecting 5-10% of women in the reproductive age. This prevalence ranging from 2.2% to 26% in adult women from 18-45 year. In a recent study the prevalence of a confirmed diagnosis of PCOS in adolescents aged 10 to 19 years was 5-15%, which increased to 10-22%. When undiagnosed cases with documented symptoms qualifying for PCOS according to NIH (National institute of Health) criteria were included. PCOS is a complex endocrine disorder which is most common in women of reproductive age. PCOS may first present in adolescence, but the incidence of PCOS in adolescence is not known, as diagnostic criteria for PCOS in the adolescent age-group is still not defined, PCOS symptoms tend to overlap with normal pubertal changes making the diagnosis even more challenging. The objective is to study prevalence and symptomatology of polycystic ovary syndrome (PCOS) in adolescent girls.Methods: Prospective Cross sectional study between April 2018 and March 2019. 150 adolescent girls aged 10 to 19 years attending OPD with oligomenorrhea, irregular menstrual cycle, obesity and/or hirsutism were advised for biochemical, hormonal, and ultrasonographic evaluation for diagnosis of PCOS on the basis of Rotterdam's criteria at the Department of Obstetrics and Gynaecology, Krishna Institute of Medical Sciences, Deemed University, Karad, Maharashtra, India.Results: Prevalence of PCOS in the study was 17.33% in the study group.Conclusions: PCOS is increasingly encountered during adolescence, although the overall prevalence is low and evaluation of PCOS in adolescents is challenging. At this age, lifestyle modification is imperative to prevent long-term metabolic and reproductive complications
