Synthesis of PbS nanocrystallites using a novel single molecule precursors approach: X-ray single-crystal structure of Pb(S2CNEtPri)2

The synthesis and characterisation of some lead(II) dithiocarbamato complexes Pb(S2CNRR¾)2 is reported. These compounds were used as single molecule precursors to produce nanocrystalline PbS by their thermolysis in trioctylphosphine oxide. The optical and morphological properties of the resulting PbS nanocrystallites were investigated; the influence of experimental parameters, such as precursor, growth time and temperature, on the final nanodispersed materials is also reported

Exploring to Bangkok Chaay Rak Chaay (Gay Men) Accessing Health Services in Thailand

Health services are central to the provision of services for those affected by HIV including, prevention, health promotion and treatment. Access to health services for gay men is significant in increasing their knowledge associated with issues relevant to HIV so that they can better protect and care for themselves. Aim: This ethnographic study sought to clarify and further understand the experience of Bangkok’s gay men and their access to health services relevant to HIV issues. Methods: The data collection was conducted between May and August, 2014. 45 to 60 minutes Face to face interview and digital audio recording were utilised for the data collection processes. Semi structured in-depth interviews undertaken at the Thai Red Cross Research Centre, Bangkok. All interview transcripts were translated from Thai to English. The NVivo program version 10 was utilised to organise the data coding and theming. Result: This study identified that there are few specific clinics for gay men with HIV in Thailand. Additionally, information associated with HIV and other related concerns are required to be more accurate and specific to men living with HIV. Many chaay rak chaay face difficulties accessing services, including a lack of information, privacy concerns and inadequate provision of services. Conclusion: the specific clinic and information relevant HIV issues need to be more readily available and widely circulated. Moreover, health care services should be aware of the privacy issues and personal confidentially issues. Such approaches toward providing services for gay me in Bangkok may assist in eliminating some of the many barriers faced by gay men when accessing health services in the city

A congestion sensitive approach to modelling road networks for air quality management

This research establishes an approach to modelling a congested road network for air quality management, which enables the assessment of traffic management solutions that may create only subtle changes in the traffic flow regimes. Road network emissions have been calculated using standard factors taking into account details of vehicle fleet composition, average speeds and road type. Additionally, the use of microsimulation traffic modelling in conjunction with an instantaneous emissions model (IEM) has been adopted to allow comparison between methodologies and enable congestion sensitive analysis of the impact of air quality management measures on the network. Findings from microscale modelling have revealed that the use of an IEM to calculate emissions as an input for air quality dispersion modelling significantly improved the performance of the dispersion modelling when measured against monitored data. Moreover, this methodology has been successfully applied to assess the performance of a traffic scheme in Durham, UK

CE20006

The 2020 Irish Anglerfish and Megrim Survey (IAMS) took place from 23rd February to 18th March (area 7bcjk) and 12-21st April 2020 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass and abundance indices for anglerfish (Lophius piscatorius and L. budegassa) and megrim (Lepidorhombus whiffiagonis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution, relative abundance and biology of other commercially exploited species. For the second year, additional sampling took place in deep water (up to 1,500m) in order to monitor the recovery of exploited deep-water species following the decline of the deep-water fisheries in Irish waters. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim Survey (SIAMISS) and uses the same gear and fishing practices

Serrated Lesions of the Colorectum: Review and Recommendations From an Expert Panel

Serrated lesions of the colorectum are the precursors of perhaps one-third of colorectal cancers. Cancers arising in serrated lesions are usually in the proximal colon, and account for a disproportionate fraction of cancer identified after colonoscopy

Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects

Copy number variants (CNVs) have been strongly implicated in the genetic etiology of schizophrenia (SCZ). However, genome-wide investigation of the contribution of CNV to risk has been hampered by limited sample sizes. We sought to address this obstacle by applying a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls. A global enrichment of CNV burden was observed in cases (OR=1.11, P=5.7×10−15), which persisted after excluding loci implicated in previous studies (OR=1.07, P=1.7 ×10−6). CNV burden was enriched for genes associated with synaptic function (OR = 1.68, P = 2.8 ×10−11) and neurobehavioral phenotypes in mouse (OR = 1.18, P= 7.3 ×10−5). Genome-wide significant evidence was obtained for eight loci, including 1q21.1, 2p16.3 (NRXN1), 3q29, 7q11.2, 15q13.3, distal 16p11.2, proximal 16p11.2 and 22q11.2. Suggestive support was found for eight additional candidate susceptibility and protective loci, which consisted predominantly of CNVs mediated by non-allelic homologous recombination
