Gender, Entrepreneurship and Socioeconomic Reparation in Jammu & Kashmir

The entrepreneurship growth is being recognized as a serviceable means of tackling Jammu and Kashmir’s [J&K] socioeconomic challenges of high unemployment, and unbalanced distribution of income. The unemployment rates revealed by National Sample Survey Office (NSSO) for the state presents a depressed image of the condition of women in the state. According to the NSSO employment position of females in urban areas are worse than that of men. The indicators were analyzed and found that the females in urban areas are unemployed and the rate is at 11.7 percent. And the same pointer for the unemployment rate for the male population is hovering at 6.7 percent and the figure at all-India for the woman (urban) joblessness rate is at 7.9 percent. It is observed that existing policies overlook the gender as a potential input for addressing the grave issue. Despite this females have proven their mettle using their peculiar gender nature effectively and efficiently in small and micro business which calls for an immediate attention by the government towards promotion of women in entrepreneurship.

Role of hysteroscopy and histopathology in evaluating patients with abnormal uterine bleeding

Background: Abnormal uterine bleeding is one of the leading causes for seeking gynaecological advice. The aim and objectives of the study was to determine the pattern of hysteroscopic abnormalities and histopathological features of Abnormal Uterine Bleeding and to correlate hysteroscopic findings with histopathological findings.Methods: The present study “Role of Hysteroscopy and Histopathology in Evaluating patients with Abnormal Uterine Bleeding” was an observational study carried out in the Postgraduate Department of Obstetrics and Gynaecology and Postgraduate Department of Pathology of Government Medical college, Srinagar after obtaining clearance from the institutional ethical committee. The period of the study was One and a Half Years from April 2014 to September 2015.Results: The most common abnormality detected by hysteroscopy was Endometrial Hyperplasia (27 cases, 27%) followed by endometrial polyps (21 cases, 21%). Endometrial Hyperplasia was the most common abnormality found in Menorrhagia followed by polyps while polyps were the most common finding in polymenorrhea and endometrial hyperplasia was the most common pathology in postmenopausal bleeding. Hysteroscopy had a sensitivity of 93.2%, specificity of 83.9%, positive predictive value of 82%, Negative Predictive Value of 94% in diagnosing etiology of abnormal uterine bleeding.Conclusions: This study confirms that hysteroscopy has a definitive role in evaluating patients with abnormal uterine bleeding and hysteroscopy and histopathology complement each other in the evaluation of a patient with Abnormal uterine bleeding

Effective Adsorption of Hexavalent Chromium and Divalent Nickel Ions from Water through Polyaniline, Iron Oxide, and Their Composites

Water pollution caused by industrial wastes containing heavy metals and dyes is a major environmental problem. This study reports on the synthesis, characterization, and utilizations of Polyaniline (PANI) and its composites with Fe3O4 for the removal of hexavalent chromium Cr(VI) and divalent nickel Ni(II) ions from water. The adsorption data were fitted in Freudlich, Langmuir, Tempkin, Dubbanin–Ruddishkawich (D–R), and Elovich adsorption isotherms. The Freundlich isotherm fits more closely to the adsorption data with R2 values of 0.9472, 0.9890, and 0.9684 for adsorption of Cr(VI) on Fe3O4, PANI, and PANI/Fe3O4 composites, respectively, while for adsorption of Ni(II) these values were 0.9366, 0.9232, and 0.9307 respectively. The effects of solution pH, initial concentration, contact time, ionic strength, and adsorbent dosage on adsorption behavior were investigated. The adsorption ability of composites was compared with pristine PANI and Fe3O4 particles. Activation energy and other thermodynamic properties such as changes in enthalpy, entropy, and Gibbs free energy indicated spontaneous and exothermic adsorption

Study on Direct Synthesis of Energy Efficient Multifunctional Polyaniline-Graphene Oxide Nanocomposite and Its Application in Aqueous Symmetric Supercapacitor Devices

The synthesis of promising nanocomposite materials can always be tricky and depends a lot on the method of synthesis itself. Developing such synthesis routes, which are not only simple but also can effectively catch up the synergy of the compositing material, is definitely a worthy contribution towards nanomaterial science. Carbon-based materials, such as graphene oxide, and conjugative polymers, such as conductive polyaniline, are considered materials of the 21st century. This study involves a simple one pot synthesis route for obtaining a nanocomposite of polyaniline and graphene oxide with synergistic effects. The study was carried out in a systematic way by gradually changing the composition of the ingredients in the reaction bath until the formation of nanocomposite took place at some particular reaction parameters. These nanocomposites were then utilized for the fabrication of electrodes for aqueous symmetric supercapacitor devices utilizing gold or copper as current collectors. The device manifested a good capacitance value of 264 F/g at 1 A/g, magnificent rate performance, and capacitance retention of 84.09% at a high current density (10 A/g) when gold sheet electrodes were used as the current collectors. It also showed a capacitance retention of 79.83% and columbic efficiency of 99.83% after 2000 cycles

Physical, Chemical, and Electrochemical Properties of Redox-Responsive Polybenzopyrrole as Electrode Material for Faradaic Energy Storage

Polybenzopyrrole (Pbp) is an emerging candidate for electrochemical energy conversion and storage. There is a need to develop synthesis strategies for this class of polymers that can help improve its overall properties and make it as suitable for energy storage applications as other well-studied polymers in this substance class, such as polyaniline and polypyrrole. In this study, by synthesizing Pbp in surfactant-supported acidic medium, we were able to show that the physicochemical and electrochemical properties of Pbp-based electrodes are strongly influenced by the respective polymerization conditions. Through appropriate optimization of various reaction parameters, a significant enhancement of the thermal stability (up to 549.9 °C) and the electrochemical properties could be achieved. A maximum specific capacitance of 166.0 ± 2.0 F g−1 with an excellent cycle stability of 87% after 5000 cycles at a current density of 1 A g−1 was achieved. In addition, a particularly high-power density of 2.75 kW kg−1 was obtained for this polybenzopyrrole, having a gravimetric energy density of 17 Wh kg−1. The results show that polybenzopyrroles are suitable candidates to compete with other conducting polymers as electrode materials for next-generation Faradaic supercapacitors. In addition, the results of the current study can also be easily applied to other systems and used for adaptations or new syntheses of advanced hybrid/composite Pbp-based electrode materials

A polybenzopyrrole@nickel oxide (Pbp@NiO) nanocomposite was synthesized by an oxidative chemical one-pot method and tested as an active material for hybrid electrodes in an electrochemical supercapattery device. The as-prepared composite material exhibits a desirable 3D cross-linked nanostructured morphology and a synergistic effect between the polymer and metal oxide, which improved both physical properties and electrochemical performance. The unprocessed material was characterized by X-ray diffraction, FTIR and UV–Vis spectroscopy, scanning electron microscopy/energy disperse X-ray analysis, and thermogravimetry. The nanocomposite material was deposited without a binder on gold current collectors and investigated for electrochemical behavior and performance in a symmetrical two- and three-electrode cell setup. A high specific capacity of up to 105 C g$^{-1}$ was obtained for the Pbp@NiO-based electrodes with a gravimetric energy density of 17.5 Wh kg$^{-1}$, a power density of 1,925 W kg$^{-1}$, and excellent stability over 10,000 cycles
