Hill of Banchory Geothermal Energy Project Feasibility Study Report

This feasibility study explored the potential for a deep geothermal heat project at Hill of Banchory, Aberdeenshire. The geology of the Hill of Fare, to the north of Banchory, gives cause to believe it has good geothermal potential, while the Hill of Banchory heat network, situated on the northern side of the town, offers a ready-made heat customer. The partners in the consortium consisted of academics and developers with relevant expertise in deep geothermal energy, heat networks, and financial analysis, together with representatives of local Government. They conducted geological fieldwork around the Hill of Fare, engaged with local residents to establish their attitudes to geothermal energy, and built business models to predict the conditions under which the heat network at Hill of Banchory would be commercial if it utilised heat from the proposed geothermal well. They also estimated the potential carbon emission reductions that could be achieved by using deep geothermal energy, both at Hill of Banchory and more widely

A model of circulating private debt

We study the possible specialness of circulating as opposed to noncirculating private securities using models whose equilibria imply the existence of both. The models are pure exchange setups with spatial separation and with the potential for a variety of intertemporal trades. We find a sense in which unregulated circulating private securities are troublesome. It can happen that in order for an equilibrium to exist, the amounts of circulating debts issued at the same time in spatially and informationally separated markets have to satisfy restrictions not implied by individual maximization and market clearing in each market separately.

Equine Suture Exostosis: A Review of Cases from a Multicenter Retrospective Study

Simple summary Suture exostosis is a condition affecting the horse's head. The connections between the bone plates that form the horse's face have been shown to react to insult. Horses will then develop a swelling along the face that may be painful. Little is known about this condition and the present research project aimed to investigate horses presented to equine clinics with symptoms of the disorder. It was revealed that the condition can form following trauma, underlying sinus disease, following a surgery or without any apparent cause. Various treatment options to resolve the condition have been reported and the outcomes of those are described in the paper. Most consistently the proper diagnosis and identification and removal of potential bone sequestra are crucial for a timely resolution. Suture exostosis is an intriguing and not uncommon pathology that has to be included in the differential diagnosis for horses with swelling of the head. Although several singular case reports have been published, no large case series is available. The aim of this study is to report a multicentric retrospective collection of suture exostosis cases. Data concerning horses with suture exostosis in the facial region were collected retrospectively. Information regarding breed, age, gender, history, imaging findings, initiated treatment, response to treatment and follow up was recorded. One hundred and five cases of various breeds were reported. Analysis revealed the cases could be grouped into four entities: 45 developed following sino-nasal surgery, 23 following trauma, seven with underlying sinus pathology and 25 idiopathic. Treatment consisted of sequestra removal, plate fixation, antimicrobial and anti-inflammatory drugs or no treatment. Whereas initial localized pain fades within few days or weeks, resolution or reduction of the swelling was obtained in most cases after 3 months to 1.5 years. The etiopathogenesis of suture exostosis seems to consist of different entities. Identification of an underlying cause, particularly the presence of a bone sequester and infection is important to speed up resolution and before concluding an idiopathic case. When performing sinusotomies, it is important to provide as little trauma as possible to the surgical site in order to prevent suture exostosis as a complication

Modulation of NFAT-dependent gene expression by the RhoA signaling pathway in T cells

We have reported previously that p115Rho guanine nucleotide exchange factor, its upstream activator Gα13, and its effector RhoA are able to inhibit HIV-1 replication. Here, we show that RhoA is able to inhibit HIV-1 gene expression through the NFAT-binding site in the HIV long-terminal repeat. Constitutively active NFAT counteracts the inhibitory activity of RhoA, and inhibition of NFAT activation also inhibits HIV-1 gene expression. We have shown further that RhoA inhibits NFAT-dependent transcription and IL-2 production in human T cells. RhoA does not inhibit nuclear localization of NFAT but rather, inhibits its transcriptional activity. In addition, RhoA decreases the level of acetylated histone H3, but not NFAT occupancy, at the IL-2 promoter. These data suggest that activation of RhoA can modulate IL-2 gene expression by inhibiting the transcriptional activity of NFAT and chromatin structure at the IL-2 promoter during T cell activation

A reassuring presence: An evaluation of Bradford District Hospice at Home service

Within the United Kingdom, a developing role for primary care services in cancer and palliative care has resulted in an increase in palliative home care teams. The provision of professional care in the home setting seeks to provide necessary services and enhanced choice for patients whose preference is to die at home. A mismatch between patient preference for home death and the actual number of people who died at home was identified within Bradford, the locality of this study. In response to this mismatch, and reflecting the policy environment of wishing to enhance community service provision, the four Primary Care Trusts (PCTs) in the city sought to offer support to patients who wished to remain in their own homes through the final stages of a terminal illness. To offer this support they set up a dedicated hospice at home team. This would provide services and support for patients in achieving a dignified, symptom free and peaceful death, allowing families to maximise time spent together. The aim of the study was to evaluate the Bradford hospice at home service from the perspective of carers, nurses and General Practitioners. Postal questionnaires were sent to carers (n = 289), district nurses (n = 508) and GP's (n = 444) using Bradford's hospice at home service. Resulting quantitative data was analysed using the Statical Package for Social Sciences (SPSS) and qualitative data was analysed using grounded theory techniques. The data from carers, district nurses and GPs provide general support for the Bradford hospice at home service. Carers valued highly the opportunity to 'fulfil a promise' to the individual who wished to be cared for at home. District nurses and GPs cited the positive impact of access to specialist expertise. This was a 'reassuring presence' for primary healthcare teams and offered 'relief of carer anxiety' by providing prompt, accessible and sensitive care. Carers and health professionals welcomed the increased possibility of patients being cared for at home. The study identified the need to focus on improving skill levels of staff and on ensuring continuity of care

Spacecraft Dormancy Autonomy Analysis for a Crewed Martian Mission

Current concepts of operations for human exploration of Mars center on the staged deployment of spacecraft, logistics, and crew. Though most studies focus on the needs for human occupation of the spacecraft and habitats, these resources will spend most of their lifetime unoccupied. As such, it is important to identify the operational state of the unoccupied spacecraft or habitat, as well as to design the systems to enable the appropriate level of autonomy. Key goals for this study include providing a realistic assessment of what "dormancy" entails for human spacecraft, exploring gaps in state-of-the-art for autonomy in human spacecraft design, providing recommendations for investments in autonomous systems technology development, and developing architectural requirements for spacecraft that must be autonomous during dormant operations. The mission that was chosen is based on a crewed mission to Mars. In particular, this study focuses on the time that the spacecraft that carried humans to Mars spends dormant in Martian orbit while the crew carries out a surface mission. Communications constraints are assumed to be severe, with limited bandwidth and limited ability to send commands and receive telemetry. The assumptions made as part of this mission have close parallels with mission scenarios envisioned for dormant cis-lunar habitats that are stepping-stones to Mars missions. As such, the data in this report is expected to be broadly applicable to all dormant deep space human spacecraft

Dynamics of direct inter-pack encounters in endangered African wild dogs

Aggressive encounters may have important life history consequences due to the potential for injury and death, disease transmission, dispersal opportunities or exclusion from key areas of the home range. Despite this, little is known of their detailed dynamics, mainly due to the difficulties of directly observing encounters in detail. Here, we describe detailed spatial dynamics of inter-pack encounters in African wild dogs (Lycaon pictus), using data from custom-built high-resolution GPS collars in 11 free-ranging packs. On average, each pack encountered another pack approximately every 7 weeks and met each neighbour twice each year. Surprisingly, intruders were more likely to win encounters (winning 78.6% of encounters by remaining closer to the site in the short term). However, intruders did tend to move farther than residents toward their own range core in the short-term (1 h) post-encounter, and if this were used to indicate losing an encounter, then the majority (73.3%) of encounters were won by residents. Surprisingly, relative pack size had little effect on encounter outcome, and injuries were rare (<15% of encounters). These results highlight the difficulty of remotely scoring encounters involving mobile participants away from static defendable food resources. Although inter-pack range overlap was reduced following an encounter, encounter outcome did not seem to drive this, as both packs shifted their ranges post-encounter. Our results indicate that inter-pack encounters may be lower risk than previously suggested and do not appear to influence long-term movement and ranging

2013-2014 Kentucky & Tennessee Tobacco Production Guide

Tobacco growers in Kentucky and Tennessee have faced many challenges during the past two years, including weather, labor availability, and rising production costs. However, there have been opportunities as well. Some buying stations have closed or moved, but new buyers have come into the market and contract volumes have been stable overall. Good quality burley tobacco is in relatively short supply, and this has offered opportunities to those who have been able to overcome weather and labor challenges and produce good crops. These changes have had different impacts in different regions of both states, based largely on where buying stations closed and opened. Dark tobacco contract volumes have been more stable than burley, but dark tobacco growers have had challenges as well, including shortages of wood and quality sawdust needed to produce dark-fired tobacco. Labor costs have continued to rise as tobacco growers struggled to keep pace with changes in the H-2A labor program that allows them to legally employ migrant workers. Uncertainty about future regulatory action still hangs over the entire tobacco industry but does not seem as foreboding as two years ago. Overall, tobacco remains an important commodity in the agricultural economy of the region as growers prepare for future seasons

2015-2016 Burley and Dark Tobacco Production Guide

Burley and dark tobacco growers in the U.S. make hundreds of decisions every growing season that impact the yield and quality of the crops that they produce. These decisions may include choosing appropriate varieties, planning effective pest control measures or perhaps deciding the best time to top or harvest a crop. Increasingly, tobacco growers are being required by the industry to record and justify their management decisions and actions. The most comprehensive example of this is the U.S. Tobacco Good Agricultural Practices (GAP) program that was initiated during the 2013 growing season and expanded in 2014. Under this program, all growers who sell tobacco to GAP Connections member organizations are required to attend training sessions on the principals of GAP and to keep detailed records of their production practices. Training requirements may change, but growers are currently required to attend training every season in which they plan to sell tobacco. Additional information about U.S. Tobacco GAP can be found by contacting GAP Connections. The written U.S. Tobacco GAP guidelines often refer growers to “University Tobacco Production Guides” for specific recommendations regarding management decisions. The information and recommendations provided in this guide have been developed and reviewed by tobacco production specialists and scientists at the University of Kentucky, University of Tennessee, Virginia Tech, and North Carolina State University. The purpose of this multi-state guide is to provide all burley and dark tobacco growers with the most current research-based recommendations for the production of high-yielding, high-quality tobacco. The guide provides advice on industry-accepted practices that may be applied across the burley and dark tobacco growing regions, although in some cases, growers may be referred to their local extension offices for additional information relevant to their specific situation
