Complexes of Some Group(IV) Metal Halides with 5-Aminoindazole

The synthesis and characterisation of Sn(IV) halides, Ge(IV), Ti(IV) and Zr(IV) chloride complexes of the type MX4 : Li_ 2 with 5-aminoindazole has been made. The possible structure of these complexes has been proposed on the basis of elemental analysis and infrared spectroscopy. The IR spectra suggest unidentate behaviour of the ligand involving pyrrole nitrogen in all the cases except the tin(IV) bromide complex, where the ligand exhibits its bidentate nature, involving the pyridyl nitrogen. An octahedral geometry has been proposed for all the complexes. In the case of MX4 :\u27L type complexes, except for SnBr4 : L, an octahedral halogen bridged structure has been proposed

A Prospective Observational Study of Spectrum of Tropical Infections in Pregnancy in a Tertiary Care Hospital in Mumbai, Maharashtra

Background and aims: Pregnancy is associated with several hormonal and mechanical changes in the body. The tropical infections that most commonly affect pregnant females are malaria, dengue, leptospirosis and typhoid. These tropical infections cause many medical complications in pregnancy by causing anemia, thrombocytopenia, bleeding and inflammatory reactions. Therefore, we conducted a study to evaluate the clinical presentation, complications and outcome of tropical infections in pregnancy. Material and methods: The present study was conducted at a tertiary care hospital in Mumbai, Maharashtra over a period of 1½ year (January 2018 to June 2019) after getting approval from Institutional Ethics Committee. In this study, 250 pregnant patients admitted in medicine ward, obstetrics and gynecology ward, and ICU with symptoms and signs of tropical infections and age more than 18 years, who gave written informed consent, were included. Results: The most common age group amongst the study population was 20 to 24 years (41.6%), followed by 25 to 29 years (40%) and 30 to 35 years (18.4%). Most of the study population had gestational age of 1 to 12 weeks (61.6%), followed by 13 to 28 weeks (31.6%) and more than 28 weeks (6.8%). Most of the study population had parity 2 (46.8%), followed by parity 1 (43.2%), parity 3 (6.8%) and parity 4 (3.2%). The most common clinical features amongst the study population was fever (62%), followed by headache (32.8%), nausea (30.8%), pain in abdomen (26.4%) and petechiae (26%). The most common infections amongst the study population were malaria (11.2%), dengue (8%), leptospirosis (6%) and enteric fever (5.2%). The most common medical complications were bleeding due to thrombocytopenia (TCP) (6.8%), followed by serositis (5.2%), ARDS (4.4%), meningitis (2.8%), subconjunctival hemorrhage (2.8%) and encephalitis (1.4%). Complicated infections were seen in 30% of the study population. Conclusion: All pregnant women must be evaluated at primary care centers properly in their antenatal visits for their parity status and any associated risk factors and diseases. By doing this, we can reduce many tropical infections, complications and maternal mortality in early stage of pregnancy

Irrigation application efficiency and uniformity of water distribution using multi-outlet pipe and resource conservation technologies

Irrigation experiments were conducted during November to April under wheat crop in the winter season of 2012-13 and 2013-14 in the farmer’s field at Galibkhedi village located in Karnal District, Haryana State, India. In the study, collapsible multi-outlet pipe (MOP) along with single outlets pipe (SOP) was tested in farmer’s field under wheat cultivation. Irrigation was carried out in five treatments including tillage (T) with SOP and MOP; zero-tillage (ZT) with SOP and MOP, and furrow irrigation with raised bed (FIRB). Iso-time profile of waterfront spreading and advance indicated that irrigation water distribution was uniform under the plot irrigated using MOP as compared to plot irrigated using SOP. In addition, water distribution was uniform under zero tilled plots as compared to tilled plot. Results implied that MOP has several advantages over SOP in terms of application efficiency (AE) and uniformity of water distribution. Average application efficiency for the first study year was found to be in the order of ZT-MOP (82.41%) > FIRB (76.79%) > ZT-SOP (75.25%) > T-MOP (74.85%) > T-SOP (69.79%). Average application efficiency for the second study year was found to be in the same order as first year with some deviation in values. In the second year values of mean application efficiencies were ZT-MOP (82.58%) > FIRB (77.13%) > ZT-SOP (73.04%) > T-MOP (69.65%) > T-SOP (66.13%). Overall, this study concludes that irrigation under wheat crop using collapsible multi-outlet pipe (MOP) with zero tillage practices is a suitable option for surface irrigation that accomplishes uniform distribution of water with higher application efficiency

Functionalization of Carbon Surfaces Tunes the Redox Stability of Polyoxometalate@Carbon Electrodes

The use of redox-active polyoxometalates (POMs) offers unique opportunities for the development of advanced functional materials, but the use of such systems is often limited by their instability in operando. To enhance the functional stability of POMs, they are often immobilized onto solid supports, though complex POM hybridization strategies are usually required. Herein, we describe a simple and scalable method for the fabrication of POM-based redox materials. Our method involves functionalizing an inexpensive carbon black (Vulcan XC-72R) support with oxygenic groups, which act as stabilizing anchor points for the Wells–Dawson POM K6[P2W18O62]. X-ray photoelectron spectroscopy and electron microscopy confirm that oxidation of the carbon surfaces promotes interactions between the POMs and the carbon surfaces. Scanning electron microscopy shows that the surface area of carbon decreases upon oxidation, and this is confirmed by Brunauer–Emmett–Teller analysis, where the specific surface area of carbon decreases from 234 to 108 m2 g–1. Solid-state voltammetry shows that the electrochemical properties of the POMs are retained by the hybrid material. Four successive, reversible reductions of the attached POMs are observed when the composite is in contact with 1.0 mol dm–3 H2SO4, corresponding to the [P2W18O62]6–/[P2W18O62]7–, [P2W18O62]7–/[P2W18O62]8–, [P2W18O62]8–/[H2P2W18O62]8–, and [H2P2W18O62]8–/[H4P2W18O62]8– redox couples. In contrast, formation of a composite using unoxidized carbon only shows the [P2W18O62]6–/[P2W18O62]8–, [P2W18O62]8–/[H2P2W18O62]8–, and [H2P2W18O62]8–/[H4P2W18O62]8– couples. Finally, voltammetric analysis shows that the composite formed using oxidized carbon shows very little degradation in any of its 4 redox process over 500 charging/discharging cycles, whereas that formed using unoxidized carbon almost completely loses its redox activity after 250 cycles. These observations have significant implications for the sustainable synthesis of functional molecular redox materials for future energy storage technologies

Synthesis and Antifungal Activity of Some Organotin(IV) Carboxylates

Six diorganotin(IV) carboxylates prepared by reacting diorganotin(IV) dichlorides with the respective silver carboxylate have been tested for antifungal activity against Aspergillus. niger, Aspergilluus flavus and Pencillium. citrinum in Sabourand dextrose broth. The compounds generally exhibit greater fungitoxicity than the diorganotin(IV) dichlorides and the carboxylic acids from which they were synthesized. In keeping with the generally accepted notion that the organotin moiety plays an important role in deciding the antifungal activity of an organotin compound, the diphenyltin(IV) compounds were more active than their di-n-butyltin(IV) analogues. However, the order of increasing fungitoxicity of the compounds parallels that of the uncomplexed carboxylic acids. The implications of the results are discussed

Fostering Community Preparedness to Cope with Drought: new initiatives and results from a study involving ODL and ICT from South Central India

Drought has emerged as a key concern in the context of climate variability induced by Climate Change processes and over a billion people are vulnerable, according to UN estimates. Drought preparedness is recognized as the preferred way to cope over relief, and information is the key. Improved access to contemporary ICT in the form of mobile phones and the Internet can help address the challenge of information deficiency in this matter. We have tried to develop an integrated approach for improving the capacity of rural communities by bringing together agricultural information with methods of ODL and effective exchange or delivery using video- conferencing. This has also enabled skill building among vulnerable rural communities in the use of color-coded maps derived from satellite imagery and GIS platforms. ICRISAT in partnership with a community based all- women micro-credit organization, the Adarsha Mahila Samaikhya (AMS), in South Central India has developed this blend of techniques to help the AMS and rural communities to anticipate how vulnerable their villages would be to drought in a season. This is an ongoing partnership, and we report here on joint studies carried out during March 2008- September 2009
