Development and testing of a virtual energy meter using the Labview Environment

The quantity of electric energy utilized by a home, a business, or an electrically powered device is measured by an electricity meter, also known as an electric meter, electrical meter, or energy meter. Electric meters located at customers' locations are used by electric providers for billing. They are usually calibrated in billing units, with the kilowatt hour being the most popular (kWh). Typically, they are read once each billing cycle. When energy savings are sought during specific times, some meters may monitor demand, or the highest amount of electricity used during a specific time. Additionally, some meters feature relays for load shedding in response to responses during periods of peak load. The amount of electrical energy consumed by users is measured by a Watt-hour meter, also known as an energy meter. To charge the electricity usage by loads like lights, fans, and other appliances, utilities put these gadgets everywhere, including in households, businesses, and organizations. Watts are a fundamental power unit. A kilowatt is equal to one thousand watts. One kilowatt is regarded as one unit of energy used if used for one hour. These meters calculate the product of the instantaneous voltage and current readings and provide instantaneous power. This power is distributed over a period and is used during that time. Depending on the supply used by home or commercial installations, these may be single or three phase meters. These can be linked directly between line and load for minor service measurements, such as home consumers. However, step-down current transformers must be installed for greater loads to handle their higher current demands.

Extranodal nasal NK/T-Cell Lymphoma: a rare oral presentation and FASN, CD44 and GLUT-1 Expression

O linfoma de células natural killers (NK)/T extranodal é um tumor maligno agressivo com características clinicopatológicas distintas, caracterizadas por invasão e destruição vasculares, necrose proeminente, fenótipo linfocítico citotóxico e uma forte associação com o vírus Epstein-Barr. Relatamos aqui um caso de linfoma de células NK/T nasal extranodal, envolvendo o seio maxilar, assoalho de órbita, e interessantemente estendendo-se para a cavidade oral através do osso alveolar e mucosa vestibular, preservando o palato, levando a um diagnóstico inicial equivocado de doença periodontal agressiva. Ainda, nós investigamos pela primeira vez a expressão imunoistoquímica das proteínas Fatty acid sinthase (FASN) e glucose transporter 1 (GLUT-1) nesta neoplasia. FASN revelou uma forte expressão citoplasmática nas células neoplásicas, enquanto GLUT-1 e CD44 foram negativas. Estes achados sugerem que a expressão de FASN e a perda de CD44 podem estar envolvidas na patogênese do linfoma de células NK/T nasal extranodal, e que GLUT-1 não deve participar da adaptação das células tumorais ao ambiente de hipóxia. Estudos adicionais com séries maiores são necessários para confirmar nossos resultados iniciais.

Effects of hypoxic culture conditions on umbilical cord-derived human mesenchymal stem cells

Following cultivation of distinct mesenchymal stem cell (MSC) populations derived from human umbilical cord under hypoxic conditions (between 1.5% to 5% oxygen (O-2)) revealed a 2- to 3-fold reduced oxygen consumption rate as compared to the same cultures at normoxic oxygen levels (21% O-2). A simultaneous measurement of dissolved oxygen within the culture media from 4 different MSC donors ranged from 15 mu mol/L at 1.5% O-2 to 196 mu mol/L at normoxic 21% O-2. The proliferative capacity of the different hypoxic MSC populations was elevated as compared to the normoxic culture. This effect was paralleled by a significantly reduced cell damage or cell death under hypoxic conditions as evaluated by the cellular release of LDH whereby the measurement of caspase 3/7 activity revealed little if any differences in apoptotic cell death between the various cultures. The MSC culture under hypoxic conditions was associated with the induction of hypoxia-inducing factor-alpha (HIF-1 alpha) and an elevated expression of energy metabolism-associated genes including GLUT-1, LDH and PDK1. Concomitantly, a significantly enhanced glucose consumption and a corresponding lactate production could be observed in the hypoxic MSC cultures suggesting an altered metabolism of these human stem cells within the hypoxic environment.

Challenges and threats to implementing the fight against doping in sport

Prominent doping cases in certain sports have recently raised public awareness of doping and reinforced the perception that doping is widespread. Efforts to deal with doping in sport have intensified in recent years, yet the general public believes that the 'cheaters' are ahead of the testers. Therefore, there is an urgent need to change the antidoping strategy. For example, the increase in the number of individual drug tests conducted between 2005 and 2012 was approximately 90 000 and equivalent to an increase of about 50%, yet the number of adverse analytical findings remained broadly the same. There is also a strikingly different prevalence of doping substances and methods in sports such as a 0.03% prevalence of anabolic steroids in football compared to 0.4% in the overall WADA statistics. Future efforts in the fight against doping should therefore be more heavily based on preventative strategies such as education and on the analysis of data and forensic intelligence and also on the experiences of relevant stakeholders such as the national antidoping organisations, the laboratories, athletes or team physicians and related biomedical support staff. This strategy is essential to instigate the change needed to more effectively fight doping in sport.

Bay 41-2272 Activates Host Defence Against Local And Disseminated Candida Albicans Infections.

In our previous study, we have found that 5-cyclopropyl-2-[1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]-pyrimidin-4-ylamine (BAY 41-2272), a guanylate cyclase agonist, activates human monocytes and the THP-1 cell line to produce the superoxide anion, increasing in vitro microbicidal activity, suggesting that this drug can be used to modulate immune functioning in primary immunodeficiency patients. In the present work, we investigated the potential of the in vivo administration of BAY 41-2272 for the treatment of Candida albicans and Staphylococcus aureus infections introduced via intraperitoneal and subcutaneous inoculation. We found that intraperitoneal treatment with BAY 41-2272 markedly increased macrophage-dependent cell influx to the peritoneum in addition to macrophage functions, such as spreading, zymosan particle phagocytosis and nitric oxide and phorbol myristate acetate-stimulated hydrogen peroxide production. Treatment with BAY 41-2272 was highly effective in reducing the death rate due to intraperitoneal inoculation of C. albicans, but not S. aureus. However, we found that in vitro stimulation of peritoneal macrophages with BAY 41-2272 markedly increased microbicidal activities against both pathogens. Our results show that the prevention of death by the treatment of C. albicans-infected mice with BAY 41-2272 might occur primarily by the modulation of the host immune response through macrophage activation.

BAY 41-2272 activates host defence against local and disseminated Candida albicans infections

The response of a Swiss university hospital's palliative care consult team to assisted suicide within the institution.

In January 2006 the Centre Hospitalier Universitaire Vaudois (CHUV), a large university hospital in Lausanne, Switzerland, became the first hospital in Switzerland to allow assisted suicide (AS) in exceptional cases within its walls. However, euthanasia is illegal. This decision has posed several ethical and practical dilemmas for the hospital's palliative care consult service. To address these, the team embarked on a formal process of open dialogue amongst its members with the goal of identifying a collective response and position. This process involved meetings every 4 to 6 weeks over the course of 10 months. An iterative process unfolded. One of the principal dilemmas relates to finding a balance between the team's position against AS and the patient's autonomy and the institution's directive. Although all team members expressed opposition to AS, there were mixed opinions as to whether or not the team members should be present during the act if requested so by patients. Some thought this could be misinterpreted as complicity in the act and could send out mixed messages to the public and other health professionals about palliative care. Others felt that the team's commitment to nonabandonment obliged them to be present even if they did not provide the drug or give any advice or assistance. The implications of nonabandonment are explored, as are several other questions such as whether or not the teams are obliged to provide detailed information on AS when requested by patients.

Antidiabetic activity of Vaccinium vitis-idaea, a medicinal plant from the traditional pharmacopeia of the James Bay Cree

L’incidence du diabète chez les premières nations du Canada est plus de trois fois celle du reste du pays, dû, en partie, aux traitements culturellement inappropriés. Notre projet vise à traiter le diabète chez ces populations à partir de leur pharmacopée de médicine traditionnelle afin d’améliorer l’acceptation des traitements. En utilisant une approche ethnobotanique, notre équipe a identifié 17 plantes médicinales utilisées pour traiter des symptômes du diabète par les Cris d'Eeyou Istchee (Baie James, Québec). Parmi eux, l'extrait éthanolique de baies de Vaccinium vitis-idaea a montré un effet stimulateur sur le transport du glucose dans les cellules musculaires squelettiques et les adipocytes en culture. Le but de cette thèse était d’élucider les mécanismes par lesquels cet extrait exerce ses effets anti-hyperglycémiants, d’identifier ses principes actifs et de confirmer in vivo, son efficacité. Les résultats démontrent que V.vitis a augmenté le transport du glucose dans les cellules musculaires en cultures, C2C12 et L6 et a stimulé la translocation des transporteurs GLUT4 dans les cellules L6. L'extrait a également inhibé la respiration dans les mitochondries isolées du foie du rat. Cet effet est semblable à celui de la metformine et en lien avec la production du stress métabolique et l'activation de l'AMPK. De plus, la voie de signalisation de l’insuline ne semble pas être impliquée dans le mécanisme d’action de V. vitis. Le fractionnement guidé par la stimulation du transport du glucose a mené à l'isolation des principes actifs; la quercétine, la quercétine-3-O-galactoside, et la quercétine-3-O-glucoside. Comparable à l'extrait brut, ses composés ont stimulé la voie AMPK. Cependant, la quércetine était la seule à inhiber la respiration mitochondriale. Pour valider l'effet de V.vitis in vivo, l'extrait (1% dans l'eau de boisson) a été administré aux souris KKAy pendant 10 jours. La glycémie et le poids corporel ont été significativement réduits par V.vitis. Ces effets ont été associés à une diminution de la prise alimentaire, ce qui suggère que V.vitis diminue l'appétit. L'étude pair-fed a confirmé que les effets de V.vitis sont, majoritairement, dû à la réduction de l’appétit. De plus, V.vitis a augmenté la teneur en GLUT4 dans le muscle squelettique, a stimulé la iv phosphorylation de l'ACC et a augmenté les niveaux de PPAR-α dans le foie des souris KKAy. Ces effets se voient être additifs à l’effet anorexigène de V. vitis. Au cours du fractionnement bioguidé de l’extrait, l’ester méthylique de l'acide caféique (CAME), un produit formé lors de la procédure du fractionnement, a démontré un effet stimulateur puissant sur le transport du glucose dans les celules C2C12 et donc un potentiel anti-diabétique. Pour identifier d'autres acides caféique active (AC) et pour élucider leurs relations structure-activité et structure-toxicité, vingt dérivés AC ont été testés. Outre CAME, quatre composés ont stimulé le transport du glucose et ont activé l'AMPK suite au stress métabolique résultant d'un découplage de la phosphorylation oxydative mitochondriale. L’activité nécessite une fonction d’AC intacte dépourvu de groupements fortement ionisés et ceci était bien corrélée avec la lipophilicite et la toxicité. Les résultats de cette thèse soutiennent le potentiel thérapeutique de V. vitis, ses composés actifs ainsi que de la famille de l’AC et pour la prévention et le traitement du diabète.

Admiralty Bay Benthos Diversity-A census of a complex polar ecosystem

A thorough census of Admiralty Bay benthic biodiversity was completed through the synthesis of data, acquired from more than 30 years of observations. Most of the available records arise from successive Polish and Brazilian Antarctic expeditions organized since 1977 and 1982, respectively, but also include new data from joint collecting efforts during the International Polar Year (2007-2009). Geological and hydrological characteristics of Admiralty Bay and a comprehensive species checklist with detailed data on the distribution and nature of the benthic communities are provided. Approximately 1300 species of benthic organisms (excluding bacteria, fungi and parasites) were recorded from the bay`s entire depth range (0-500 m). Generalized classifications and the descriptions of soft-bottom and hard-bottom invertebrate communities are presented. A time-series analysis showed seasonal and interannual changes in the shallow benthic communities, likely to be related to ice formation and ice melt within the bay. As one of the best studied regions in the maritime Antarctic Admiralty Bay represents a legacy site, where continued, systematically integrated data sampling can evaluate the effects of climate change on marine life. Both high species richness and high assemblage diversity of the Admiralty Bay shelf benthic community have been documented against the background of habitat heterogeneity. (C) 2010 Elsevier Ltd.

Evaluation of the Role of Access Providers Discussion of Dutch Pirate Bay Case Law and Introducing Principles on Directness, Effectiveness, Costs, Relevance, and Time

Internet service providers (ISPs) play a pivotal role in contemporary society because they provide access to the Internet. The primary task of ISPs – to blindly transfer information across the network – has recently come under pressure, as has their status as neutral third parties. Both the public and the private sector have started to require ISPs to interfere with the content placed and transferred on the Internet as well as access to it for a variety of purposes, including the fight against cybercrime, digital piracy, child pornography, etc. This expanding list necessitates a critical assessment of the role of ISPs. This paper analyses the role of the access provider. Particular attention is paid to Dutch case law, in which access providers were forced to block The Pirate Bay. After analysing the position of ISPs, we will define principles that can guide the decisions of ISPs whether to take action after a request to block access based on directness, effectiveness, costs, relevance and time.

The effect of triage team on time-in-department in a pediatric emergency department

Objective. To determine whether the use of a triage team would reduce the average time-in-department in a pediatric emergency department by 25%.^ Methods. A triage team consisting of a physician, a nurse, and a nurse's assistant initiated work-ups and saw patients who required minimal lab work-up and were likely to be discharged. Study days were randomized. Our inclusion criteria were all children seen in the emergency center between 6p and 2a Monday-Friday. Our exclusion criteria included resuscitations, inpatient-inpatient transfers, left without being seen, leaving against medical advice, any child seen outside of 6p-2am Monday-Friday and on the weekends. A Pearson-Chi square was used for comparison of the two groups for heterogeneity. For the time-in-department analysis, we performed a 2 sided t-test with a set alpha of 0.05 using Mann Whitney U looking for differences in time-in-department based on acuity level, disposition, and acuity level stratified by disposition. ^ Results. Among urgent and non-urgent patients, we found a statistically significant decrease in time-in-department in a pediatric emergency department. Urgent patients had a time-in-department that was 51 minutes shorter than patients seen on non-triage team days (p=0.007), which represents a 14% decrease in time-in-department. Non-urgent patients seen on triage team days had a time-in-department that was 24 minutes shorter than non-urgent patients seen on non-triage team days (p=0.009). From the disposition perspective, discharged patients seen on triage team days had a shorter time-in-department of 28 minutes as compared to those seen on non-triage team days (p=0.012). ^ Conclusion. Overall, there was a trend towards decreased time-in-department of 19 minutes (5.9% decrease) during triage team times. There was a statistically significant decrease in the time-in-department among urgent patients of 51 minutes (13.9% decrease) and among discharged patients of 28 minutes (8.4% decrease). Urgent care patients make up nearly a quarter of the emergency patient population and decreasing their time-in-department would likely make a significant impact on overall emergency flow.^

Under the veneer of decentralisation. Ukraine's modernisation efforts stall due to lack of local government reform. OSW Commentary No. 102, 2013-02-12

President Viktor Yanukovych and his Party of Regions have been repeating the pledge to decentralise power in Ukraine and to give local government a greater decision-making role ever since the party appeared on the Ukrainian political scene. The implementation of this reform is crucial both for the economic recovery of Ukraine’s regions and the overall modernisation efforts of the Ukrainian state. At present relations between central government and the regions are regulated by Soviet-era legislation that fails to address the modern-day challenges facing Ukraine. The political elite in the country, including the opposition, appear to have reached consensus on the importance of the decentralisation reform. The first attempts to implement changes in this area were made in the late 1990s, followed by a comprehensive reform programme developed between 2007 and 2009 by Yulia Tymoshenko’s government. In 2012, the Constitutional Assembly under the President of Ukraine appointed a team of experts who drafted a document detailing the reform of local government and the territorial organisation of power1. The document envisages the implementation of what effectively are two major reforms: (1) an administrative-territorial reform, which would help consolidate the fragmented administrative structure, creating larger and more economically self-sufficient administrative units, and (2) local government reform, focusing on creating clearly defined powers for local authorities with a view to securing government funding for specific tasks delegated from central government. Nonetheless, despite these measures, and in spite of the rhetoric coming from President Yanukovych and other members of the Party of Regions, it seems unlikely that the reform will be implemented in the foreseeable future. A series of concrete political decisions taken by the president over the past three years indicate that Yanukovych has not abandoned his plan to build a highly centralised political system. This in turn limits the capacity to govern of local authorities and further restricts the sources of funding for Ukraine’s regions. This apparent resistance to change stems from the fact that by implementing the proposed reforms, the president and his political allies would be forced to relinquish much of their control over the political processes taking place in the country and would have to free up the distribution of budgetary resources between Kyiv and the regions. The implementation of the reform within the specified timeframe (i.e. by 2015) is also unlikely due to the upcoming presidential election and the deteriorating economic situation in Ukraine. Without a comprehensive reform of local government, however, Ukraine will be unable to undertake effective modernisation measures, which are key for the socio-economic development of the country’s regions.

An appraisal of adaptive management planning and implementation in ecological restoration: case studies from the San Francisco Bay Delta, USA

Adaptive management has been defined and redefined in the context of natural resource management, yet there are few examples of its successful application in ecological restoration. Although the 2009 Delta Reform Act now legally requires adaptive management for all restoration efforts in the Sacramento-San Joaquin Delta, in California, USA, projects in this region still encounter problems with implementation. We used a comparative case study analysis to examine adaptive management planning and implementation both in and around the Delta, assessing not only why adaptive management is not yet well implemented, but also what changes can be made to facilitate the adaptive management approach without sacrificing scientific rigor. Adaptive management seems to be directly and indirectly affected by a variety of challenges and convoluted by ambiguity in both planning documents and practitioner’s interpretations of the concept. Addressing these challenges and ambiguities at the project level may facilitate the adaptive management process and help make it more accessible to practitioners.
