Considering the impact of situation-specific motivations and constraints in the design of naturally ventilated and hybrid buildings
A simple logical model of the interaction between a building and its occupants is presented based on the principle that if free to do so, people will adjust their posture, clothing or available building controls (windows, blinds, doors, fans, and thermostats) with the aim of achieving or restoring comfort and reducing discomfort. These adjustments are related to building design in two ways: first the freedom to adjust depends on the availability and ease-of-use of control options; second the use of controls affects building comfort and energy performance. Hence it is essential that these interactions are considered in the design process. The model captures occupant use of controls in response to thermal stimuli (too warm, too cold etc.) and non-thermal stimuli (e.g. desire for fresh air). The situation-specific motivations and constraints on control use are represented through trigger temperatures at which control actions occur, motivations are included as negative constraints and incorporated into a single constraint value describing the specifics of each situation. The values of constraints are quantified for a range of existing buildings in Europe and Pakistan. The integration of the model within a design flow is proposed and the impact of different levels of constraints demonstrated. It is proposed that to minimise energy use and maximise comfort in naturally ventilated and hybrid buildings the designer should take the following steps: 1. Provide unconstrained low energy adaptive control options where possible, 2. Avoid problems with indoor air quality which provide motivations for excessive ventilation rates, 3. Incorporate situation-specific adaptive behaviour of occupants in design simulations, 4. Analyse the robustness of designs against variations in patterns of use and climate, and 5. Incorporate appropriate comfort standards into the operational building controls (e.g. BEMS)
Antenatal-Based Pilot Psychosocial Intervention to Enhance Mental Health of Pregnant Women Experiencing Domestic and Family Violence in Nepal.
Survivors of domestic and family violence (DFV) report poorer quality of life and worsening mental health. This study evaluated the effect of a counseling and education intervention on the mental health and help-seeking behaviors among pregnant women living with DFV. A parallel pilot randomized controlled trial was performed among 140 pregnant women attending an antenatal clinic of a tertiary hospital of Nepal. Using computer-generated random numbers, participants were randomized to the intervention group (a counseling session, an information booklet about DFV, and contact details of the counselor) or a control group (usual care plus a booklet containing contact details of local DFV support services). Outcome measures included mental health, quality of life (QOL), self-efficacy, social support, and safety planning behaviors. Analyses followed intention-to-treat, using the generalized estimating equation model. Intervention participants showed significant improvements in anxiety (β = -3.24, p < .001) and depression (β = -3.16, p < .001) at postintervention. Such improvements were also sustained at follow-up assessment (p < .001). Significant group and time interaction for QOL, social support, use of safety behaviors, and self-efficacy (p < .05) revealed a greater increase in these outcome measures among intervention participants at both follow-up assessments compared with the control group. This pilot integrated intervention showed promising outcomes in improving the mental health, social support, and the use of safety behaviors among women with DFV. This intervention could be incorporated into regular antenatal care as a strategy to identify and support victims of DFV. Larger controlled trials with longer follow-up are needed to support and expand on the current findings regarding the effectiveness of a psychosocial intervention targeting victims of DFV in resource-constrained settings
Assessment of Pesticide Use in Major Vegetables From Farmers\u27 Perception and Knowledge in Dhading District, Nepal
A field study was carried out to assess the pesticide use status in major vegetable crops from farmers\u27 perception and knowledge in Dhading, Nepal in 2019. Field study was carried with 100 commercial farmer\u27s using semi-structure questionnaire by face to face interview. This study was analyzed by categorization of farmers into small holder (51) and large holder (49) groups on the basis of mean area of vegetable cultivation (6.48 ropani). The highest amount of pesticides is needed in tomato in both large holders and small holders according to the farmer\u27s experience. Among the study farmer\u27s, 41% of them spray the pesticides by making a cocktail or mixed method and 56% follow the waiting period of 3-5 days in both of the cases. A significant positive correlation was found at 5% level of significance between the knowledge and practice pattern of waiting period of the pesticides and negative correlation was found between the Personal Protective equipment score and health hazard score. Headache was the major health hazards faced by the farmers which was higher in small holders (66.7%) as compared to the large holders (46.9%). Mask was the most used PPE by the farmer\u27s i.e. by 83% in overall. Fourty three percent of the farmer\u27s throw the pesticide containers in secret place after using of it.The use of PPE was seen lower in small holders as compared to the large holders. This study reveals the necessities of suitable program and policies regarding the knowledge, safe handling and use of pesticide among the farmer\u27s level
'We don't see because we don't ask': Qualitative exploration of service users' and health professionals' views regarding a psychosocial intervention targeting pregnant women experiencing domestic and family violence.
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
Counselling-based psychosocial intervention to improve the mental health of abused pregnant women: A protocol for randomised controlled feasibility trial in a tertiary hospital in eastern Nepal
© 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

Results of Autogenous Trephine Biopsy Needle Bone Grafting in Fractures of Radius and Ulna
Cortico-Cancellous bone graft harvested from the anterior iliac crest by the conventional open method is
associated with more morbidity and is more time consuming as compared to the percutaneous method using
trephine biopsy needle. The aim of the study was to determine whether cancellous bone graft harvested from
anterior iliac crest using trephine biopsy needle consistently achieved bone union in comminuted fractures
and fractures of more than 3 weeks duration of radius and ulna and also to determine the morbidity at the
donor site.
Autogenous cancellous bone graft was harvested percutaneously from 28 iliac crests in 16 patients and
applied at fracture sites of 30 forearm bones using a 4mm trephine biopsy needle after the fratures had been
fixed with plate and screws. The patients were followed up regularly upto 6 to 9 months post - operatively in
the OPD to determine the union status of the fractured bones and the morbidity at the donor site.
29 of the 30 fractures of the forearm bones united without any problems. The shaft of a trephine got bent
during the harvesting procedure at the beginning of the study due to improper technique.
Cancellous bone graft harvested from the anterior iliac crest results in predictable good union results in
comminuted fractures of forearm bones and also fractures presenting after 3 weeks of injury. It is also an
easier and quicker way of harvesting bone graft and is associated with lesser morbidity and earlier recovery
as compared to conventional open method.
Key Words: Bone graft, trephine, fracture of radius and ulna morbidit
Erratum: Measurement of d+ Be 7 cross sections for big-bang nucleosynthesis (Physical Review Letters (2019) 122 (182701) DOI: 10.1103/PhysRevLett.122.182701)
The cross sections of nuclear reactions between the radioisotope Be7 and deuterium, a possible mechanism of reducing the production of mass-7 nuclides in big-bang nucleosynthesis, were measured at center-of-mass energies between 0.2 and 1.5 MeV. The measured cross sections are dominated by the (d,a) reaction channel, towards which prior experiments were mostly insensitive. A new resonance at 0.36(5) MeV with a strength of ωγ=1.7(5) keV was observed inside the relevant Gamow window. Calculations of nucleosynthesis outcomes based on the experimental cross section show that the resonance reduces the predicted abundance of primordial Li7, but not sufficiently to solve the primordial lithium problem.
