The adoption of telemedicine technologies has enabled collaborative programs involving a variety of links among distributed medical structures and health officials and professionals. The use for telemedicine for transmission of medical data and the possibility for several distant physicians to share their knowledge on given medical cases provides clear benefits, but also raises several unsolved conceptual and technical challenges. The seamless exchange and access of medical information between medical structures, health professionals, and patients is a prerequisite for the harmonious development of this new medical practice. This paper proposes a new approach of semantic interoperability for enabling mutual understanding of terminologies and concepts used. The proposed semantic interoperability approach is based on conceptual graph to support collaborative activities by describing how different health specialists can apply appropriate strategies to eliminate differential medical diagnosis. Intelligent analysis strategies are used to narrow down and pinpoint medical disorders. The model proposed is fully verified by a case study in the context of elderly patients and specifically dealing with synucleinopathies, a group of neurodegenerative diseases that include Parkinson's disease (PD), dementia with Lewy bodies (DLB), pure autonomic failure (PAF) and multiple system atrophy (MSA). © 2015 Elsevier Masson SAS and European Union Geriatric Medicine Society.

Factors influencing the feeding behavior of goats include grazing management practices, type of vegetation and season, breed and stage of production, group size, and properties of diets fed in confinement. Considerable information has been gathered from visual observation during daylight. However, tools are now available to characterize the feeding behavior of goats while grazing and while in confinement throughout the day. Global positioning system collars can be used to assess horizontal and vertical distances traveled, up or down position of the head, and movement within pasture or rangeland areas. A commercially available leg activity monitor allows estimation of the number of steps and time spent standing, lying, and moving rapidly without grazing. However, these measurements do not directly determine grazing. Therefore, prediction equations based on visual observation must be developed. Classification tree analysis is a robust method in developing these equations because the decision tree can be pruned or expanded to provide the best fit. Another equipment system determines time spent eating, ruminating, and remaining idle from the pattern of jaw movement. In addition to use of n-alkanes as internal markers to estimate digestibility, their profile can provide an indication of the botanical composition of the selected diet. Automated feeding systems for confined goats permit determinations such as number of feeder visits and meals, eating time, and rate and pattern of feed intake. Heart rate measured while goats are in normal production settings can be used to predict total energy expenditure through multiplication by energy expenditure per heartbeat of individual animals. To partition the activity energy cost, an estimate of ME intake or measures of changes in body energy status and milk energy yield are needed to determine other sources of heat to be subtracted from total energy expenditure. These methods create the opportunity to gain a fuller understanding of factors influencing the feeding behavior of goats and the relationships with levels and efficiencies of production. © 2010 American Society of Animal Science.

Owing to globalisation, it became necessary for software companies to take advantage of computing skills distributed worldwide. One of the resulting problems is the difficulty to model tasks to be assigned remotely. We know how to explicitly define tasks and working methods using process technologies; thus, processes and their artefacts become important factors to be considered. This paper proposes a new approach of process modelling for its remote performance. The main advantage of this approach is to maintain collaboration among autonomous Process-centred Software Engineering Environments (PSEEs) during process performance. An implementation and discussion are proposed to validate the work. Copyright © 2011 Inderscience Enterprises Ltd.

Deposition of relatively less subcutaneous fat by goats than sheep adversely affects storage properties of meat, most importantly dehydration and cold-shortening. High concentrate diets increase internal and carcass fat in goats, including intramuscular fat though levels are less than in cattle or sheep. Levels of saturated and monounsaturated fatty acids are greater in goats consuming concentrate in confinement compared with rangeland grazing. Because the botanical composition of the diet selected by goats is more reflective of plant species available compared with cattle and sheep, changes in the botanical and chemical composition with high vs. low stocking rate or as forage mass declines with increasing stocking rate should be smaller compared with cattle and sheep, with greatest differences when browse plant species are available. The magnitude of effect of castration on carcass fatness varies considerably with plane of nutrition, although some gender comparisons have not considered stage of maturity. Limited nutrient intake maximizes lean tissue accretion and minimizes fat deposition regardless of gender. Pre-weaning growth rate is greater for single-kid litters compared with kids of multiple births depending on factors influencing milk production. Concentrate supplementation should increase pre-weaning growth when milk yield is low regardless of litter size but not with moderate-high milk yield when concentrate substitutes for milk. Genetic variability in performance traits is considerable and has been the target of various breed improvement and crossbreeding programs. Breed and genotype differences in carcass traits also exist; however, few improvement programs have included these traits in selection objectives. © 2011 Elsevier B.V.

Grasses sown with minimal tillage commonly exhibit slower establishment and lower herbage yield than those sown into a conventionally tilled seedbed. Some of the difference in performance may be attributed to differences in bulk density between tilled and untilled ground. It is not known if performance rankings of grass cultivars established in clean-tilled ground remain valid in more compacted soil characteristic of no-till seeding. Seedlings of five cultivars of Italian ryegrass (Lolium multiflorum Lam.) [IRG] and five cultivars of tall fescue [Festuca arundinacea Schreb. also known as Lolium arundinaceum Schreb. (Darbysh.)] [TF] were grown in pots of Coyle or Stephenville series soils (sandy loam and loamy sand respectively) packed to 0·75, 0·88 or 1·00 of maximum packing densities, established as 1·47 and 1·68 g cm-3 for Coyle and Stephenville soil respectively. Leaf appearance was measured until seedling harvest at 540 growing degree days after emergence. Increased bulk density decreased leaf appearance rates, reduced final leaf and tiller numbers and aerial and root biomass at harvest in both IRG and TF. Among cultivars within species, there was no difference (P > 0·05) in response to measured parameters to change in bulk density. Seedling growth and development of IRG were consistently greater than that of TF but showed greater reduction in response to increased soil bulk density. Soil strength provided a better indicator of likely seedling response to soil compaction than bulk density. The results suggest that cultivar rankings obtained under conventional tillage are likely to be valid with no-till planting. © 2010 Blackwell Publishing Ltd.

Differences between production systems based on grazing and browsing vs. use of harvested feedstuffs in confinement largely depend on specific feedstuffs and plants available and being consumed. Low forage nutrient ingestion should have relatively greater impact on tissue mobilization than milk production in early than later periods of lactation, with a transition to proportionally greater change in milk production in late lactation. However, low body condition at kidding would limit tissue energy mobilization and restrict impact of level of nutrient intake to milk yield and, likewise, tissue mobilization would be less with one vs. two or three milkings per day. As lactation advances after freshening, fat and protein levels decrease with increasing milk yield, and when production declines in mid- to late lactation, fat and protein concentrations increase. Milk production generally peaks at a parity of 3 or 4, thereafter declining slowly. Elevated somatic cell count alone in dairy goats is not a valid indication of mammary infection. Extended lactations offer opportunities to minimize or avoid seasonal fluctuations in milk production and lessen production costs. If differences in performance between suckled and machine-milked dairy goats occur, they may be restricted to or of greater magnitude during the suckling period compared with post-weaning, and differences in milk yield will either be absent or less with one kid compared with greater litter sizes. The magnitude of effects of milking frequency on milk yield is less for goats of low vs. high production potential and with low vs. high diet quality. Likewise, the effect of milking frequency is greater in early and mid-lactation when yield is higher than in late lactation, along with a shorter period of peak production with one vs. two daily milkings. Physical form of the diet can affect production and composition of goat milk, although effects appear of smaller magnitude than in dairy cattle. When tissue is mobilized to support milk production in early lactation, levels of C18:0 and C18:1 cis in milk increase and levels of medium-chain fatty acids decline. Effects of elevated levels of dietary fatty acids on specific long-chain fatty acids in milk and milk products vary with the fatty acid profile of fat sources used. © 2011 Elsevier B.V.

In 2006, Langston University (Oklahoma, USA) unveiled an on-line training and certification program for meat goat producers (http://www2.luresext.edu/training/qa.html). The program consists of 22 learning modules, including herd health, biosecurity and internal parasite control. In March 2010, an electronic survey was sent to 160 certified producers to assess impact of the training. Fifty-four surveys were completed for a response rate of 33.7%. Prior to certification, 52.8% of respondents used selective deworming criteria. Current deworming practices and percentage of responses include: FAMACHA, 43; visual condition, 28; pasture rotation-based, 15; and calendar-based, 14 (χ 2=19.02, P<0.001). When asked if individual animals or all animals in a pasture or pen received anthelmintic when deworming, 76% of respondents said that only animals requiring deworming received anthelmintic (χ 2=14.52, P<0.001). The dosage of dewormer given was most often calculated based upon table guidelines given in the certification course (54%), vs. 35% who relied on veterinarian instructions and 11% who self-determined dosage amounts (χ 2=18.22, P<0.001). Over 60% of respondents reported that prior to becoming certified they did not consult a veterinarian for use of drugs extra label. When asked how current withdrawal times for drugs not approved for goats are determined, 41% of responses reported using veterinarian instructions with an identical percentage using table guidelines from the certification course; with 19% of responses using information from the Internet (χ 2=7.32, P<0.03). Results of the survey show changes in behavior of certified goat producers when compared with previous practices in anthelmintic usage. More emphasis on the importance of veterinarian approval for lawful use of extra-label drug is needed. Changes in production practices noted imply that an on-line training course can be effective in promoting proper herd health practices for goat producers. © 2011 Elsevier B.V.

Developing more, highly qualified science and mathematics teachers is a national priority. Through funding from the National Science Foundations Robert Noyce Teacher Scholarship Program, this Phase I Noyce Teacher Scholarship project will recruit, prepare, and support twenty-four students pursuing baccalaureate degrees in a STEM discipline to simultaneously complete requirements for teacher certification in Oklahoma over a five-year period. This project is responsive to both the national and local shortage of outstanding STEM secondary teachers and to the need to diversify the teaching workforce to take advantage of the richness that this country offers. This project is a collaboration among Langston University, the Oklahoma City Community College, and Oklahoma City and Guthrie School Districts.

LU Noyce Scholar pre-service teacher candidates will be recruited from four groups: community college STEM majors; existing Langston University (LU) STEM Scholars who indicate a preference for teaching or who are not committed to pursuing graduate school in their discipline immediately upon graduation; LU undeclared majors who indicate an interest in teaching and exhibit acumen in STEM subjects such that they would pursue a degree in a STEM discipline; and pre-college students in Oklahomas high schools. This project will also leverage LUs decades of long demonstrated capabilities as the primary training resource for Oklahomas African-American secondary teachers, and its track record to develop outstanding STEM majors who will bring their core content knowledge, passion for learning and commitment to social justice to the teaching and learning enterprise. In addition to strategic recruitment activities, components of the project will include: a Pre-scholarship Support Program; LU Noyce Teacher Preparation Program; LU Noyce Program Performance, Retention, and Enrichment Experiences Program; and the LU Noyce Post-Graduation Support/Retention Program. The project builds upon and integrates a number of research-based approaches and tools, including the Competency Performance Recordings for Learning (CPRL), a teaching and learning protocol demonstrated to support students problem solving skills, and the STEM Digital Village, an online STEM learning community that supports and recognizes the Scholars activities and performance, provides educational resources, and supports monitored, education-oriented discussion beyond LUs campus. The ultimate societal benefit of this LU Robert Noyce endeavor, both within Oklahoma and nationwide, will be the development and support of a diverse group of highly qualified STEM teachers, who have a love for their STEM discipline and who are well-grounded in teaching in high-needs school districts. An external evaluator will conduct a formative and summative assessment, which will examine the impact of the online aspects of the work, as well as the indicators of success associated with the recruitment, development, and retention of the twenty-four Langston Noyce Scholars.

Agency: NSF | Branch: Standard Grant | Program: | Phase: MAJOR RESEARCH INSTRUMENTATION | Award Amount: 250.00K | Year: 2013

Today computational science, in addition to theory and experimentation, forms an essential component of scientific inquiry. High Performance Computing (HPC)enables scientific inquiry that was unthinkable just a few years ago.

Under this proposed Major Research Instrumentation Project, Langston University, HPC Center, will acquire, deploy and maintain an HPC cluster supercomputer that will support computing-intensive research and training across a broad variety of STEM disciplines. As a campus-wide shared resource, it will be available not only to all of the LU members but also to researchers across Oklahoma and will enable many areas of CDS&E research.
