GENERALIZED CAUCHY-RIEMANN SCREEN PSEUDO-SLANT LIGHTLIKE SUBMANIFOLDS OF INDEFINITE SASAKIAN MANIFOLDS

This paper deals with the study of generalized Cauchy-Riemann (in short, GCR) screen pseudo-slant lightlike submanifolds of indefinite Sasakian manifolds giving a characterization theorem with some non-trivial examples of such submanifolds. Integrability conditions of distributions D1, D2, D′1 and D′2 on GCR screen pseudo-slant lightlike submanifolds of indefinite Sasakian manifolds have been obtained. Furthermore, we obtain necessary and sufficient conditions for foliations determined by the above distributions to be totally geodesic

Low Cost Efficient Treatment for Contaminated Water

8 p.International audienceHeavy metals pose a risk of contaminating groundwater and surface water sources due to geogenic activities, industries and agricultural sources. The removal of heavy metals e.g., cadmium, lead, and zinc from drinking, industrial and irrigation water at low concentrations is a recurring challenge, especially in developing countries. Biosorption is a relatively new process that has proved to be very promising for removal of heavy metals from aqueous solutions. The removal of contaminants viz., Cd(II), Pb(II) and Zn(II) by rice husk (lignin containing material) was studied in the laboratory. Batch studies were performed to evaluate the influences of various experimental parameters like pH, initial concentration of metal ions, biosorbent dosage and contact time. The selectivity of the process is also studied. The findings show the efficiency of material for the removal these contaminants with a low concentration in the range 1-5 mg/L. The removal efficiency is up to 95%

Basics and Essentials of Medical Devices Safety Surveillance

Medical devices are being used in healthcare facilities for diagnosis, monitoring, prevention and treatment of an array of diseases. To ensure user/patient safety associated with the medical devices being used in healthcare industry, it is of utmost importance to closely monitor the adverse events associated with the medical devices through a robust, sustainable and scaled surveillance. Materiovigilance Programme of India (MvPI) provides a reliable system to report adverse events associated with medical devices. Under MvPI, various modalities to report adverse events associated with medical devices have been developed. These modalities include an editable medical device adverse event reporting form, a toll-free helpline number and a field safety corrective action form (FSCA). FSCA form is used to notify the regulatory authority and healthcare professionals on corrective actions or recall by the manufacturer. Due to the emergence of the Coronavirus disease 2019 (COVID-19) pandemic, one-page editable form has been developed to boost the adverse event reporting of Personal Protective Equipments (PPEs). MvPI also coordinates with healthcare facilities and medical device industries across the country for reporting the medical device-related adverse events. The collected scientific data is utilized to develop regulatory policies and enhance measures to ensure the quality of medical devices. All the healthcare workers are, therefore, encouraged to report adverse events to MvPI. This chapter aims to describe the systems, procedures and modalities available for the reporting of Medical Device Adverse Events (MDAEs) in India, in order to intensify the nature of reporting and creating an environment that encourages the public to perform MDAE reporting

Assessing attitude towards condom use among truck drivers at transhipment location, Meerut District, India, using multidimensional condom attitude scale

Background: In India, unsafe sex has been documented among truck drivers. This study explores the factors influencing their attitude of trucker towards condom use.Methods: A cross-sectional study design was adapted for this study in which 25 factors were chosen to assess attitude toward condom use on 7 point validated Likert scale UCLA Multidimensional Condom Attitude Scale on 5 subcomponents –Reliability, Pleasure, Stigma associated with condom use, embarrassment about negotiation and use of condom and about purchasing condom. Hundred truck drivers were recruited using convenient sampling and Mann-Whitney U and Kruskall Wallis Test were used to validate the subcomponents among those practicing unsafe sex. Results: Positive attitudes regarding reliability and effectiveness of condom were significantly higher among adult entrants and those resting more than 10 hours during journey whereas positive attitude regarding pleasure associated with condoms and stigma towards it is significantly higher among truck drivers travelled long distances and resting more than 10 hours. Conclusion: Adolescent entrants, those who have not travelled long distances and not rested more than 10 hrs requires improvement in the attitude towards condom use. Keywords: Unsafe sex; condom use; India

Adverse Drug Reactions Associated with Anti-Tuberculosis Therapy

The pharmacovigilance has been evolved as a professional and ethical practice in ensuring the safety of medicines. The Adverse Drug Reactions (ADRs) associated with the use of medicines including Anti-Tuberculous Therapy (ATT) through a robust system of pharmacovigilance helps in promoting the safety of patients at large. The occurrence of ADRs associated with the use of ATT is expected, a large number of medicines are combined and used for prolonged duration. The suspected ADRs associated with first line ATT are well documented. However, the drugs used in second line or multidrug resistant to tuberculosis (TB), namely bedaquiline, reported to cause QT prolongation in electrocardiogram reading as one of the most common ADRs. Therefore, early identification and prevention of ADRs during ATT is essential for promoting the rational use and reduce the burden of anti-microbial resistance, besides achieving better treatment outcomes

Ectopic expression of DnaJ type-I protein homolog of Vigna aconitifolia (VaDJI) confers ABA insensitivity and multiple stress tolerance in transgenic tobacco plants

Reduced crop productivity results from altered plant physiological processes caused by dysfunctional proteins due to environmental stressors. In this study, a novel DnaJ Type-I encoding gene, VaDJI having a zinc finger motif in its C-terminal domain was found to be induced early upon treatment with heat stress (within 5 min) in a heat tolerant genotype of Vigna aconitifolia RMO-40. VaDJI is induced by multiple stresses. In tobacco, ectopic expression of VaDJI reduced ABA sensitivity during seed germination and the early stages of seedling growth of transgenic tobacco plants. Concomitantly, it also improved the ability of transgenic tobacco plants to withstand drought stress by modulating the photosynthetic efficiency, with the transgenic plants having higher Fv/Fm ratios and reduced growth inhibition. Additionally, transgenic plants showed a reduced build-up of H2O2 and lower MDA levels and higher chlorophyll content during drought stress, which attenuated cell damage and reduced oxidative damage. An analysis using the qRT-PCR study demonstrated that VaDJI overexpression is associated with the expression of some ROS-detoxification-related genes and stress-marker genes that are often induced during drought stress responses. These findings suggest a hypothesis whereby VaDJI positively influences drought stress tolerance and ABA signalling in transgenic tobacco, and suggests that it is a potential gene for genetic improvement of drought and heat stress tolerance in crop plants

Exploring unsafe sexual practices among truck drivers at Meerut District, India: a cross-sectional study

Background: Despite implementation of HIV prevention programmes for truck drivers in India, unsafe sex behavior among truck drivers has been documented. Objective: The objective of this study was to assess knowledge about HIV Transmission and modes of prevention, pattern of condom use with high risk partners and explore the practice of unsafe sex and its risk factors among truck drivers. Methods: This exploratory cross-sectional study design was conducted on a recruited convenient sample of 100 truck drivers above 18 years from March to May 2015. Binary logistic regression was used to compute unadjusted odds ratio [95% Confidence Interval] for establishing association of risk factors with unsafe sex. Results: Overall, only 7% had complete knowledge about HIV/AIDS transmission and prevention. 54% of truck drivers have sex with a high risk partner (commercial sexual worker or men having sex with men) and thirty-eight percent reported unsafe sexual practices due to inconsistent condom use with them. The various risk factors found significantly associated with unsafe sex were mean age of first intercourse (OR= 0.92, 95% CI: 0.75 \u2013 0.97), access to pornography (OR = 4.4, 95% CI: 1.8 \u2013 10.7) and conuming psychoactive substance before sex (OR = 4.06, 95% CI: 1.09 \u2013 15.02). Conclusion: Socio-demographic, occupational factors, pornography access and consuming psychoactive substances seems to influence the sexual behaviour of truckers
