    Uranium (U) and many trace elements are enriched in phosphorus fertilizers. Concentrations up to 260 mg/kg P2O5 indicate the potential of U contamination of the environment. Two fertilized long-time soil monitoring fields (BDF) in Lower Saxony have higher top soil concentration than comparable unfertilized top soils sampled at the Green-Belt in the vicinity of the BDFs. Extraction experiments could show that fertilizer-derived U is easier mobilized and hence might be leached faster to the groundwater than the geogenic U in soils. Groundwater analyses in an area of intense agricultural production show U in correlation with nitrate, indicating an impact of anthropogenic fertilization on the U concentration in shallow groundwater. The results of soil, soil extract and groundwater analyses are giving indications for fertilizer-derived U leaching to groundwater aquifers and hence show the potential hazard for our drinking water resources

    © 2019 Author(s). Published by BMJ. Introduction The strong correlation between domestic and family violence (DFV) and mental health has been well documented in studies. Pregnancy is a period when both DFV and mental distress tend to occur and/or accentuate. Although limited, available evidence from developed countries has shown continual support and education as psychological first aid that can reduce DFV and improve mental health. However, there is significantly less number of studies from resource-constrained countries; thus, there continues to be a substantial gap in knowledge and awareness regarding effective interventions for DFV. Methods and analysis A two-arm randomised trial with a nested qualitative study has been planned to assess feasibility and treatment effect estimates of a counselling-based psychosocial intervention among pregnant women with a history of abuse. A total of 140 pregnant women who meet the inclusion criteria will be recruited into the study. Block randomisation will be used to allocate women equally into two groups. The intervention group will receive a counselling session, an information booklet and continuous support by a researcher, while women in the control group will receive contact information of local support services. Feasibility measures, such as rates of recruitment, consent and retention, will be calculated. Qualitative interviews with participants and healthcare providers will explore the acceptability and usability of the intervention. Outcome measures, such as psychological distress, quality of life, social support and self-efficacy, will be measured at baseline, 4 weeks postintervention and 6 weeks postpartum. Ethics and dissemination This study has obtained ethical approval from the Griffith University Human Research Ethics Committee, the Nepal Health Research Council and the Institutional Review Board of a tertiary hospital in Dharan, Nepal. The findings will be disseminated via peer-reviewed publications and conference presentations and will be used to inform a future multicentre trial

    INTRODUCTION:Given the relative recency of Domestic and Family Violence (DFV) management as a field of endeavour, it is not surprising that interventions for addressing DFV is still in its infancy in developing countries. In order to maximise the success of an intervention, it is important to know which aspects of the intervention are considered important and helpful by service providers and service users. This study, therefore, examined the acceptability of an antenatal-based psychosocial intervention targeting DFV in Nepal and explored suggestions for improving the program in future. MATERIALS AND METHODS:Intervention participants and health care providers (HCPs) were interviewed using semi-structured interviews. Data were audio-recorded and thematic analysis was used to analyse the data. Final codes and themes were identified using an iterative review process among the research team. RESULTS:Themes emerging from the data were grouped into domains including perceptions towards DFV, impact of the intervention on women's lives and recommendations for improving the program. DFV was recognised as a significant problem requiring urgent attention for its prevention and control. Intervention participants expressed that they felt safe to share their feelings during the counselling session and got opportunity to learn new skills to cope with DFV. The majority of the participants recommended multiple counselling sessions and a continued provision of the service ensuring the intervention's accessibility by a large number of women. DISCUSSION:This is the first study to document the perspectives of women and HCPs regarding an antenatal-based intervention targeting psychosocial consequences of DFV in Nepal. There was a clear consensus around the need to engage, support and empower victims of DFV and the intervention was well received by the participants. Ensuring good mental health and wellbeing among victims of DFV requires work across individual, organisational and community levels

    Lulu is an indigenous breed of cattle (Bos taurus) found in high altitude regions of western Nepal. Population of Lulu cattle has been declining due to introgression with other exotic breeds to increase milk productivity. Here we aimed at finding potential approach for conserving Lulu cattle and its assets by studying the milk contents and investigating which variant of beta-casein protein is present in this breed. Beta caseins are an abundant protein in cow milk with A1 and A2 being the most common genetic variants of this protein. Consumption of A1 type of milk has numerous health-related complications whereas A2 type of milk has numerous human health promoting factors. We used restriction fragment length polymorphism (RFLP) for determining the A1 and A2 variant of beta casein in Lulu cattle. For performing DNA extraction, we collected (n = 18) blood samples of Lulu from Mustang and (n=17) Nepal Agriculture research council farm. The amplified fragments in 3% agarose at 251bp and 213bp respectively confirmed the presence of both A1 and A2 gene in Lulu; however, A2 was of greater abundance. Our study indicated that Lulu has A2 variant of beta-casein predominantly. The gene frequency of A1A1 is 0, A1A2 is 0.06 and A2A2 is 0.94. We further found that the allele frequency of A1 and A2 is 0.03 and 0.97 respectively. We designed special primer for sequencing CSN2 genes since A2 type beta casein gene was predominantly seen on Lulu. The sequencing result further supports our RFLP result as most of our samples have “C” nucleotide SNP in amplified CSN2 gene sequence. The Chi-square value of the current study is 0.04 which supports Hardy-Weinberg equilibrium inferring that Lulu cattle are still in the pure state, where there is no genetic introgression with the exotic breed for the sake of improvement of productivity

    BACKGROUND:Mental health needs of victims of domestic and family violence are often overlooked. A booklet was designed to help women update their knowledge and skills in effective coping with domestic and family violence and support them in developing effective stress reduction and problem management techniques. In addition, this booklet is believed to serve as a reference for further use. This paper describes the development process and validation of the information booklet. This booklet was used during an intervention trial conducted in Nepal to educate abused pregnant women. METHODS:This methodological study involved three stages: bibliographical survey, development of the booklet, and validation by specialists in the relevant fields and representatives of the target audiences. A total of eight experts, currently working in the field of domestic violence and/or midwifery, and 15 representatives of the target participants were involved in the validation process. A minimum Content Validity Index of 0.78 was considered for content validation, and minimum agreement of 75% for face validation. RESULTS:The booklet presented a global Content Validity Index of 0.92. The overall level of agreement within the target participants was 86.3%, which was higher than the minimum recommended level. Both subject experts and participants positively evaluated the adequacy, coverage and readability of contents of the booklet. CONCLUSIONS:The booklet was validated using content and face validity. This validated booklet is expected to be an effective tool for communication that would help pregnant women cope better with domestic and family violence and adopt strategies to remain emotionally healthy

    In heavy fermions the relaxation dynamics of photoexcited carriers has been found to be governed by the low energy indirect gap Eg resulting from hybridization between localized moments and conduction band electrons. Here, carrier relaxation dynamics in a prototype Kondo insulator YbB12 is studied over a large range of temperatures and over three orders of magnitude. We utilize the intrinsic nonlinearity of dynamics to quantitatively determine microscopic parameters, such as electron-hole recombination rate. The extracted value reveals that hybridization is accompanied by a strong charge transfer from localized 4 f levels. The results imply the presence of a hybridization gap up to temperatures of the order of Eg/kB ≈ 200 K, which is extremely robust against electronic excitation. Finally, below 20 K the data reveal changes in the low energy electronic structure, attributed to short-range antiferromagnetic correlations between the localized levels

    On the background of ever increasing HIV transmission in our community through various routes, the psychosocial factors related with intravenous drug abuse has become necessary to be studied. Aim of the study was to assess the Socio-psychological factors that influence people to use drugs, especially to use Injectable drugs. We enrolled a sample of 393 Intravenous drug users, all male, in the Kathmandu Valley. Participants were administered a semi structured proforma to assess the psychosocial issues related with the drug intravenous drug abuse. Mean age of the sample was 27.76+ 4.86 years. Majority were single, unemployed, Hindu and by caste Newars, with education more than high school (SLC or more). The first psychoactive substance use by most of them was cannabis. The most frequently used psychoactive substance was injection Buprenorphine (Tidigesic), which was followed by mixture of various substances (opiates, benzodiazepines, antihistamines) and Diacetyl morphine (Brown sugar). Factors associated with the start of the drugs were for enjoyment, friend’s pressure and to alleviate mental tension. Many accepted Injectable drug use contributing to problems in mental, marital, social, economic and legal aspects of their life. Despite knowing the harms caused by the drugs majority persist on its use. A needle exchange programme has been viewed positively by many. Key words: buprenorphin, needle sharing, needle replacement, HIV transmission
