Biodegradation of rocket propellant waste, ammonium perchlorate

The short term effects of ammonium perchlorate on selected organisms were studied. A long term experiment was also designed to assess the changes incurred by ammonium perchlorate on the nitrogen and chloride contents of soil within a period of 3 years. In addition, an attempt was made to produce methane gas from anaerobic fermentation of the aquatic weed, Alternanthera philoxeroides

General practitioners\u27 awareness and management of common psychiatric disorders: a community-based survey from Karachi, Pakistan

This study assessed the knowledge and management of common psychiatric disorders by general practitioners (GPs) in Karachi, Pakistan. Structured interviews were carried out in 2009 with 360 GPs selected by cluster random sampling. Patients with psychiatric disorders were estimated to be up to 10% of the daily caseload according to 71.8% of doctors. Two-thirds of GPs were unaware of the ICD-10 diagnostic criteria for depression and anxiety disorders. Benzodiazepines were the most recognized category of medication (75.3%) and were the most commonly used medication for all mental health conditions. Fewer GPs were familiar with selective serotonin reuptake inhibitors (35.1%) or tricyclic antidepressants (20.2%). Lack of time and patients\u27 financial constraints were reported to be barriers to care. Most GPs (69.2%) had not received any recent medical education about mental health problems. Gaps in GPs\u27 knowledge about the management of mental disorders have implications for the rational use of psychotropic medications in primary care

Nitrous oxide emissions from the Arabian Sea: A synthesis

We computed high-resolution (1º latitude x 1º longitude) seasonal and annual nitrous oxide (N2O) concentration fields for the Arabian Sea surface layer using a database containing more than 2400 values measured between December 1977 and July 1997. N2O concentrations are highest during the southwest (SW) monsoon along the southern Indian continental shelf. Annual emissions range from 0.33 to 0.70 Tg N2O and are dominated by fluxes from coastal regions during the SW and northeast monsoons. Our revised estimate for the annual N2O flux from the Arabian Sea is much more tightly constrained than the previous consensus derived using averaged in-situ data from a smaller number of studies. However, the tendency to focus on measurements in locally restricted features in combination with insufficient seasonal data coverage leads to considerable uncertainties of the concentration fields and thus in the flux estimates, especially in the coastal zones of the northern and eastern Arabian Sea. The overall mean relative error of the annual N2O emissions from the Arabian Sea was estimated to be at least 65%

Study of the histidine complex of uranium(IV): synthesis, spectrophotometric, magnetic and electrochemical properties

We synthesized the novel histidine complex of uranium(IV). A 1:3 mole ratio was found between metal and ligand by the mole ratio method, while –NH2 and –COO– groups of histidine behave as coordinating sites. The IR spectra confirmed the lone pair donating or coordinating sites. The elemental analysis confirmed the stoichiometry. The bathochromic shift with an increase in the optical density in the UV-Visible range indicated that the compound and its central metal ion hold uniform electronic charge distribution. The electrochemical results indicated a quasi-reversible (neither completely reversible nor completely irreversible) oxidation of the complex to its uranium(V) product at the platinum working electrode. The quasi-reversible process shows a comparatively slow electron transfer (ET) rate with the heterogeneous electron transfer rate constant ‘ks’ (3.4 ×  10–4 cm s-1) at 50 mV s-1 and 305 ± 0.5 K. The kinetics such as diffusion and charge transfer lead the reaction with an ECE (electrochemical–chemical–electrochemical) mechanism. The thermodynamic parameters of activation such as ΔH*; 4.257 kJ mol–1, ΔS*; -2.519 × 10–3 J mol–1 K–1 and ΔG* 4.26 kJ mol–1 helped to propose an associative mechanism of the electron transfer at the platinum working electrode.                     KEY WORDS: Uranium, Histidine, Spectroscopy, Electrochemistry, Kinetics   Bull.

Production Potential of Different Pasture Grasses under Off-Season Rainfall in Arid Conditions of Bikaner, India

Livestock rearing is the important source of livelihood in arid region of Rajasthan where the crop production is unstable due to low and erratic rainfall. The rangelands and pastures are important land use system and provide main support to the livestock in the arid region of Rajasthan. Grazing of livestock is a common practice in arid zone as about 50 % of total area of western Rajasthan is available for grazing mainly for cows, sheep and goat, however, the availability of green fodder is restricted to monsoon and post monsoon months only and during rest of the period livestock graze on dry grasses and crop residues available in cultivated, fallow and wastelands and other grazing lands. The perennial grasses like Lasiurus sindicus, Cenchrus ciliaris, C. setigerus, Panicum turgidum, P. antidotale etc. with some annuals are dominated in the rangelands and pastures in the arid zone of Rajasthan. Generally these grasses are grown during rainy season but also regenerated during off-season condition when sufficient moisture is available through rainfall or irrigation and provide fodder during the lean period. Productivity of these pasture grasses were assessed during rainy season but information of the production potential during off-season is not available in literature. Therefore, present study was conducted during March to May 2015 at Arid Region Campus of CSWRI, Bikaner to assess the production potential and regeneration of different grasses during off-season under arid condition

Progressive Class-Wise Attention (PCA) Approach for Diagnosing Skin Lesions

Skin cancer holds the highest incidence rate among all cancers globally. The importance of early detection cannot be overstated, as late-stage cases can be lethal. Classifying skin lesions, however, presents several challenges due to the many variations they can exhibit, such as differences in colour, shape, and size, significant variation within the same class, and notable similarities between different classes. This paper introduces a novel class-wise attention technique that equally regards each class while unearthing more specific details about skin lesions. This attention mechanism is progressively used to amalgamate discriminative feature details from multiple scales. The introduced technique demonstrated impressive performance, surpassing more than 15 cutting-edge methods including the winners of HAM1000 and ISIC 2019 leaderboards. It achieved an impressive accuracy rate of 97.40% on the HAM10000 dataset and 94.9% on the ISIC 2019 dataset

The general practice perspective on barriers to integration between primary and social care: a London, United Kingdom-based qualitative interview study

Objective: There is an ongoing challenge of effective integration between primary and social care in the United Kingdom; current systems have led to fragmentation of services preventing holistic patient-centred care for vulnerable populations. To improve clinical outcomes and achieve financial efficiencies, the barriers to integration need to be identified and addressed. This study aims to explore the unique perspectives of frontline staff (General Practitioners and Practice Managers) towards these barriers to integration. Design: Qualitative study using semi-structured interviews and thematic analysis to obtain results. Setting: General Practices within London. Participants: 18 General Practitioners (GPs) and 7 Practice Managers (PMs) based in London with experience of working with social care. Results: The study identified three overarching themes where frontline staff believed problems exist: accessing social services, interprofessional relationships, and infrastructure. Issues with contacting staff from other sectors creates delays in referrals for patient care and perpetuates existing logistical challenges. Likewise, professionals noted a hostile working culture between sectors that has resulted in silo working mentalities. In addition to staff being overworked as well as often inefficient multidisciplinary team meetings, poor relationships across sectors cause a diffusion of responsibility, impacting the speed with which patient requests are responded to. Furthermore, participants identified that a lack of interoperability between Information Systems, lack of pooled budgets and misaligned incentives between managerial staff compound the infrastructural divide between both sectors. Conclusion: In this study, primary care staff identify intangible barriers to integration such as poor interprofessional relationships, in addition to more well-described structural issues such as insufficient funding and difficulty accessing social care. Participants believe educating the next generation of medical professionals may lead to the development of collaborative, instead of siloed, working cultures and that change is needed at both an interpersonal and institutional level to successfully integrate care

Medical school teaching on interprofessional relationships between primary and social care to enhance communication and integration of care – a pilot study

Background: A pilot study to identify if the delivery of teaching session to medical students would have the potential to enhance communication and a culture of integration between primary and social care, ultimately improving interprofessional relationships between primary and social care. Health and social care integration is a topic of great debate in the developed world and the focus of the upcoming Green Paper by the Secretary of State for Health and Social Care in the NHS. There is much uncertainty to how this should be done and is hindered by the various current barriers. The literature identifies that collaborative cultures encourage effective interprofessional relationships and that communication is vital to integration of primary and social care and should be established early in medical training. Materials and Method: The General Medical Council’s Outcomes for Graduates and Imperial College School of Medicine curriculum were reviewed out to identify outcomes relating to inter-professional relationships between primary and social care. The relevant year group was surveyed to identify if the learning objective was delivered. In order to determine if delivery of a teaching session on nurturing interprofessional relationships between primary and social care would be effective, it was delivered to early clinical years to measure benefits as a pilot study. This was devised of case-based scenarios derived from learning objectives developed with experienced health care professionals. A survey was administered before and after the teaching session to determine if the students felt they had improved with respect to the learning objectives. Results: The initial survey identified the majority of students found the learning objectives were not delivered. The teaching session found a statistically significant improvement in confidence to nurture interprofessional relationships between primary and social care. Conclusion: Effective interprofessional relationships between primary and social care, improving communication and collaborative cultures, can be effectively taught in medical school, to improve integration of primary and social care
