    2015-01-01

    The number of disputes relating to standard essential patents (SEPs), in which patent holders submit statements to commit to granting licenses on a fair, reasonable and non-discriminatory (FRAND) basis, have increased. The exercise of SEPs tends to cause problems such as hold-ups and royalty stacking and needs to be constrained somehow. Despite wide recognition of the need to address these problems, devising measures to resolve the issue has not been an easy task since various laws and princi...

    In this paper the recent ECJ judgment in Huawei is discussed in light of the earlier case law from the EU and the US. The Huawei case has been long awaited and many in academia hoped that it would finally deliver answers to if, when and on what terms access to so-called Standard Essential Patents...... would be granted under EU antitrust law. However, the question is whether Huawei is that case. On the contrary, it seems that the ECJ ruling gives room for speculation even in reference to core issues, some of which are dealt with in this paper....

  8. Combining Shigella Tn-seq data with gold-standard E. coli gene deletion data suggests rare transitions between essential and non-essential gene functionality.

    Science.gov (United States)

    Freed, Nikki E; Bumann, Dirk; Silander, Olin K

    2016-09-06

    Gene essentiality - whether or not a gene is necessary for cell growth - is a fundamental component of gene function. It is not well established how quickly gene essentiality can change, as few studies have compared empirical measures of essentiality between closely related organisms. Here we present the results of a Tn-seq experiment designed to detect essential protein coding genes in the bacterial pathogen Shigella flexneri 2a 2457T on a genome-wide scale. Superficial analysis of this data suggested that 481 protein-coding genes in this Shigella strain are critical for robust cellular growth on rich media. Comparison of this set of genes with a gold-standard data set of essential genes in the closely related Escherichia coli K12 BW25113 revealed that an excessive number of genes appeared essential in Shigella but non-essential in E. coli. Importantly, and in converse to this comparison, we found no genes that were essential in E. coli and non-essential in Shigella, implying that many genes were artefactually inferred as essential in Shigella. Controlling for such artefacts resulted in a much smaller set of discrepant genes. Among these, we identified three sets of functionally related genes, two of which have previously been implicated as critical for Shigella growth, but which are dispensable for E. coli growth. The data presented here highlight the small number of protein coding genes for which we have strong evidence that their essentiality status differs between the closely related bacterial taxa E. coli and Shigella. A set of genes involved in acetate utilization provides a canonical example. These results leave open the possibility of developing strain-specific antibiotic treatments targeting such differentially essential genes, but suggest that such opportunities may be rare in closely related bacteria.

    Oliveria decumbens as a valuable medicinal plant is extensively used in traditional medicine. clinical and standard strains causing infection resistance to antimicrobial agents, is one of the important problems in medicine. The aim of this study was to investigate the antibacterial activities and phytochemical analysis of Oliveria decumbens essential oil on the growth of some clinical and standard strains causing infection (Pseudomonas aerogenes, Escherichia coli, Streptococcus pyogenes and Staphylococcus epidermidis). Oliveria decumbens essential oil composition was identified by gas chromatography/mass spectrometry. Phytochemical analysis (alkaloids, saponins, flavone and phenolic) essential oil of the Oliveria decumbens were appraised based on qualitative methods. Several methods (disk diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)) were used to appraise the antibacterial activity of the Oliveria decumbens essential oil. Thymol (28.45%) was the major compound of Oliveria decumbens essential oil. The total phenolics content (TPC) of the essential oil positively correlated with antioxidant activity (AA). The TPC and AA of Oliveria decumbens essential oil was equal to 92.45 ± 0.70 μg GAE/mg and 164.45 ± 1.20 μg/ml, respectively. The MIC of Oliveria decumbens essential oil ranged from 1 to 8 mg/ml depending on the type of bacteria (clinical and standard strains). The MBC of Oliveria decumbens essential oil varied from 1 mg/ml to 16 mg/ml. The smallest inhibition zone diameter (IZD) on different Oliveria decumbens essential oil concentrations on P. aeruginosa. Results indicate that Oliveria decumbens essential oil can prove to be an important source of AA and antibacterial and may be used for the treatment of infection diseases.

    2016-01-01

    Full Text Available The determination of the blast protection level of laminated glass windows and facades is of crucial importance, and it is normally done by using experimental investigations. In recent years numerical methods have become much more powerful also with respect to this kind of application. This paper attempts to give a first idea of a possible standardization concerning such numerical simulations. Attention is drawn to the representation of the blast loading and to the proper description of the behaviour of the material of the mentioned products, to the geometrical meshing, and to the modelling of the connections of the glass components to the main structure. The need to validate the numerical models against reliable experimental data, some of which are indicated, is underlined.

    It makes strategic and business sense for payers and providers to collaborate on how to take substantial cost out of the healthcare delivery system. Acting independently, neither medical groups, hospitals nor health plans have the optimal mix of resources and incentives to significantly reduce costs. Payers have core assets such as marketing, claims data, claims processing, reimbursement systems and capital. It would be cost prohibitive for all but the largest providers to develop these capabilities in order to compete directly with insurers. Likewise, medical groups and hospitals are positioned to foster financial interdependence among providers and coordinate the continuum of patient illnesses and care settings. Payers and providers should commit to reasonable clinical and cost goals, and share resources to minimize expenses and financial risks. It is in the interest of payers to work closely with providers on risk-management strategies because insurers need synergy with ACOs to remain cost competitive. It is in the interest of ACOs to work collaboratively with payers early on to develop reasonable and effective performance benchmarks. Hence, it is essential to have payer interoperability and data sharing integrated in an ACO model.

  19. Autopsy consent, brain collection, and standardized neuropathologic assessment of ADNI participants: the essential role of the neuropathology core.

    Cairns, Nigel J; Taylor-Reinwald, Lisa; Morris, John C

    2010-05-01

    Our objectives are to facilitate autopsy consent, brain collection, and perform standardized neuropathologic assessments of all Alzheimer's Disease Neuroimaging Initiative (ADNI) participants who come to autopsy at the 58 ADNI sites in the USA and Canada. Building on the expertise and resources of the existing Alzheimer's Disease Research Center (ADRC) at Washington University School of Medicine, St. Louis, MO, a Neuropathology Core (NPC) to serve ADNI was established with one new highly motivated research coordinator. The ADNI-NPC coordinator provides training materials and protocols to assist clinicians at ADNI sites in obtaining voluntary consent for brain autopsy in ADNI participants. Secondly, the ADNI-NPC maintains a central laboratory to provide uniform neuropathologic assessments using the operational criteria for the classification of AD and other pathologies defined by the National Alzheimer Coordinating Center (NACC). Thirdly, the ADNI-NPC maintains a state-of-the-art brain bank of ADNI-derived brain tissue to promote biomarker and multi-disciplinary clinicopathologic studies. During the initial year of funding of the ADNI Neuropathology Core, there was notable improvement in the autopsy rate to 44.4%. In the most recent year of funding (September 1(st), 2008 to August 31(st) 2009), our autopsy rate improved to 71.5%. Although the overall numbers to date are small, these data demonstrate that the Neuropathology Core has established the administrative organization with the participating sites to harvest brains from ADNI participants who come to autopsy. Within two years of operation, the Neuropathology Core has: (1) implemented a protocol to solicit permission for brain autopsy in ADNI participants at all 58 sites who die and (2) to send appropriate brain tissue from the decedents to the Neuropathology Core for a standardized, uniform, and state-of-the-art neuropathologic assessment. The benefit to ADNI of the implementation of the NPC is very clear

Notably, industry approaches have been reviewed and features added from the lessons learned. The various severe accident management approaches vary considerably: they have different measures, different priorities for the various actions, different staff responsibilities and different sorts of communication to the off-site authorities. It appears that there is no common basis from which the approaches have been developed. In this paper, the five elements are treated which the author considers essential for proper tools to terminate severe accidents and mitigate their consequences. These five elements should be trained in well-developed drills/exercises, involving all functions of accident management. An industrial standard to define a minimum common basis, to which individual approaches should adhere and so decrease the large scatter in these approaches present now.

    2016-05-01

    The World Health Organization (WHO) has advocated the development and use of country specific Standard Treatment Guidelines (STGs) and Essential Medicines Lists (EML) as strategies to promote the rational use of medicines. When implemented effectively STGs offer many health advantages. Papua New Guinea (PNG) has official STGs and a Medical and Dental Catalogue (MDC) which serves as a national EML for use at different levels of health facilities. This study evaluated consistency between the PNG Adult STGs (2003 and 2012) and those for children (2005 and 2011) with respect to the MDCs (2002, 2012) for six chronic and/or acute diseases: asthma, arthritis, diabetes, hypertension, pneumonia and psychosis. Additionally, the potential impact of prescriber level restrictions on rational medicines use for patient's living in rural areas, where no medical officer is present, was evaluated. Almost all drugs included in the STGs for each disease state evaluated were listed in the MDCs. However, significant discrepancies occurred between the recommended treatments in the STGs with the range of related medicines listed in the MDCs. Many medicines recommended in the STGs for chronic diseases had prescriber level restrictions hindering access for most of the PNG population who live in rural and remote areas. In addition many more medicines were listed in the MDCs which are commonly used to treat arthritis, high blood pressure and psychosis than were recommended in the STGs contributing to inappropriate prescribing. We recommend the public health and rational use of medicines deficiencies associated with these findings are addressed requiring: reviewing prescriber level restrictions; updating the STGs; aligning the MDC to reflect recommendations in the STGs; establishing the process where the MDC would automatically be updated based on any changes made to the STGs; and developing STGs for higher levels of care. © The Author 2015.

    In this paper, a new formulation of nasal spray was set up based on the extract of lemon pulp, obtained by using a new solid-liquid technology of extraction, added to pure Aloe juice, soluble propoli, and essential oils of Ravensara and Niaouly. It was tested in a clinical study in which 100 subjects were recruited for a period of one month. Nasal scraping was used for collecting samples and after the application of the May-Grünwald Giemsa standard technique, glass slides were analysed by using optical microscope with a 1000x oil immersion. A control group constituted of ten people was recruited as control and this group was administered with physiological solution (saline solution). The comparison of results obtained before and after the application of nasal spray showed a total reduction of eosinophils granulocytes and mast cells; clinical data were confirmed by improvement of clinical pictures of patients. The lemon-based nasal spray was a good alternative to conventional medicine for the treatment of perennial and seasonal allergic and vasomotor rhinopathy. PMID:23304560

  11. Essential Medicines in National Constitutions

    Science.gov (United States)

    Toebes, Brigit; Hogerzeil, Hans

    2016-01-01

    Abstract A constitutional guarantee of access to essential medicines has been identified as an important indicator of government commitment to the progressive realization of the right to the highest attainable standard of health. The objective of this study was to evaluate provisions on access to essential medicines in national constitutions, to identify comprehensive examples of constitutional text on medicines that can be used as a model for other countries, and to evaluate the evolution of constitutional medicines-related rights since 2008. Relevant articles were selected from an inventory of constitutional texts from WHO member states. References to states’ legal obligations under international human rights law were evaluated. Twenty-two constitutions worldwide now oblige governments to protect and/or to fulfill accessibility of, availability of, and/or quality of medicines. Since 2008, state responsibilities to fulfill access to essential medicines have expanded in five constitutions, been maintained in four constitutions, and have regressed in one constitution. Government commitments to essential medicines are an important foundation of health system equity and are included increasingly in state constitutions. PMID:27781006

    To estimate the minimal gene set required to sustain bacterial life in nutritious conditions, we carried out a systematic inactivation of Bacillus subtilis genes. Among approximate to4,100 genes of the organism, only 192 were shown to be indispensable by this or previous work. Another 79 genes were...... predicted to be essential. The vast majority of essential genes were categorized in relatively few domains of cell metabolism, with about half involved in information processing, one-fifth involved in the synthesis of cell envelope and the determination of cell shape and division, and one-tenth related...... to cell energetics. Only 4% of essential genes encode unknown functions. Most essential genes are present throughout a wide range of Bacteria, and almost 70% can also be found in Archaea and Eucarya. However, essential genes related to cell envelope, shape, division, and respiration tend to be lost from...

    Full Text Available Introduction: Palatal myoclonus is a rare condition presenting with clicking sound in ear or muscle tremor in pharynx. There are two varieties: essential and symptomatic. Various treatment options exists ranging from watchful observation to botulinum toxin injection. We have not found any reported case of palatal myoclonus from our country. Here we present a case of essential palatal myoclonus managed with clonazepam. Case report: A young female presented in Ear Nose and Throat clinic with complain of auditory click and spontaneous rhythmic movement of throat muscles for eight months. On examination, there was involuntary, rhythmic contraction of bilateral soft-palate, uvula, and base of tongue. Neurological, eye, and peripheral examination were normal. A diagnosis of essential palatal myoclonus was made. It was managed successfully with clonazepam; patient was still on low dose clonazepam at the time of making this report. Conclusion: Essential palatal myoclonus can be clinically diagnosed and managed even in settings where MRI is not available or affordable.

  11. Calcium, essential for health

    Science.gov (United States)

    Martínez de Victoria, Emilio

    2016-07-12

    Calcium (Ca) is the most abundant mineral element in our body. It accounts for about 2% of body weight. The functions of calcium are: a) functions skeletal and b) regulatory functions. Bone consists of a protein matrix that mineralizes mainly with calcium (the most abundant), phosphate and magnesium, for it is essential an adequate dietary intake of Ca, phosphorus and vitamin D. The ionic Ca (Ca2+) is essential to maintain and / or perform different specialized functions of, virtually, all body cells cellular. Because of its important functions Ca2+ must be closely regulated, keeping plasma concentrations within narrow ranges. For this reason there is an accurate response against hypocalcemia or hypercalcemia in which the parathormone, calcitriol, calcitonin and vitamin K are involved. Ca intakes in the Spanish population are low in a significant percentage of the older adult’s population, especially in women. The main source of Ca in the diet is milk and milk derivatives. Green leafy vegetables, fruits and legumes can be important sources of Ca in a Mediterranean dietary pattern. The bioavailability of dietary Ca depends on physiological and dietary factors. Physiological include age, physiological status (gestation and lactation) Ca and vitamin D status and disease. Several studies relate Ca intake in the diet and various diseases, such as osteoporosis, cancer, cardiovascular disease and obesity.

The book addresses the need for DSP architecture design that maps advanced DSP algorithms to hardware in the most power- and area-efficient way. The key feature of this text is a design methodology based on a high-level design model that leads to hardware implementation with minimum power and area. The methodology includes algorithm-level considerations such as automated word-length reduction and intrinsic data properties that can be leveraged to reduce hardware complexity. From a high-level data-flow graph model, an architecture exploration methodology based on linear programming is used to create an array of architectural solutions tailored to the underlying hardware technology. The book is supplemented with online material: bibliography, design examples, CAD tutorials and custom software.

  15. Are Archetypes Essential?

    Science.gov (United States)

    Colman, Warren

    2018-06-01

    This paper distinguishes between Jung's theoretical discourse regarding the archetypes and his phenomenological account of numinous experience. For this author, the initial attraction of 'my Jung' came from both the vivid Romanticism of his descriptions of the anima and the apparent 'ground of being' offered by his theory of archetypes. However, the essentialism inherent to archetypal theory in general and the anima in particular has necessitated a re-evaluation of Jung's theory in terms of emergence theory. My own version of this emphasises the role of symbols in the constitution of affect through collective human action in the world. In this reconfiguration, the visceral energy of numinous experience is retained while the problematic theory of archetypes is no longer needed. © 2018, The Society of Analytical Psychology.

  17. Essentials of nonlinear optics

    CERN Document Server

    Murti, Y V G S

    2014-01-01

    Current literature on Nonlinear Optics varies widely in terms of content, style, and coverage of specific topics, relative emphasis of areas and the depth of treatment. While most of these books are excellent resources for the researchers, there is a strong need for books appropriate for presenting the subject at the undergraduate or postgraduate levels in Universities. The need for such a book to serve as a textbook at the level of the bachelors and masters courses was felt by the authors while teaching courses on nonlinear optics to students of both science and engineering during the past two decades. This book has emerged from an attempt to address the requirement of presenting the subject at college level. A one-semester course covering the essentials can effectively be designed based on this.

In addition to recording activities of the past year, there is also extended discussion of the strategic issues facing the industry, and the planned responses of the industry as a whole, as well as responses by individual member companies. With regard to a collective response, the Association expects significant advances in the industry's downstream business from automated distribution, which enables utilities to remotely monitor, coordinate and operate distribution components in real-time mode. Beyond that, CEA proposes to deal with the mounting pressures facing the electricity sector on the basis of a five point plan which comprises (1) establishment of an investment climate to ensure future electricity supply; (2) moving government and industry towards smart and effective regulation; (3) working to ensure a sustainable future for the next generation; (4) fostering innovation and accelerating skill development. and (5) building a strong Canadian electricity system while strengthening North American institutional arrangements. With recurring references to the blackout in August 2003, the five point plan stresses mandatory reliability standards as a means to strengthen the electricity grid in the context of North American institutional arrangements, of which the most significant example is CEA's active involvement in the North American Electric Reliability Council (NERC). The extensive discussion of the industry's collective responses to the challenges facing the industry is followed by one-page reviews of the plans and objectives of CEA's 26 member companies representing the industry from coast to coast

  9. Essential Specification Elements for Heat Exchanger Replacement

    Energy Technology Data Exchange (ETDEWEB)

    Bower, L.

    2015-07-01

    Performance upgrade and equipment degradation are the primary impetuses for a nuclear power plant to engage in the large capital cost project of heat exchanger replacement. Along with attention to these issues, consideration of heat exchanger Codes and Standards, material improvements, thermal redesign, and configuration are essential for developing User’s Design Specifications for successful replacement projects. The User’s Design Specification is the central document in procuring ASME heat exchangers. Properly stated objectives for the heat exchanger replacement are essential for obtaining the materials, configurations and thermal designs best suited for the nuclear power plant. Additionally, the code of construction required and the applied manufacturing standard (TEMA or HEI) affects how the heat exchanger may be designed or configured to meet the replacement goals. Knowledge of how Codes and Standards affect design and configuration details will aid in writing the User’s Design Specification. Joseph Oat Corporation has designed and fabricated many replacement heat exchangers for the nuclear power industry. These heat exchangers have been constructed per ASME Section III to various Code-Years or ASME Section VIII-1 to the current Code-Year also in accordance with TEMA and HEI. These heat exchangers have been a range of like-for-like replacement to complete thermal, material and configuration redesigns. Several examples of these heat exchangers with their Code, Standard and specification implications are presented. (Author.

    2017-01-01

    Since ancient times, folk medicine and agro-food science have benefitted from the use of plant derivatives, such as essential oils, to combat different diseases, as well as to preserve food. In Nature, essential oils play a fundamental role in protecting the plant from biotic and abiotic attacks to which it may be subjected. Many researchers have analyzed in detail the modes of action of essential oils and most of their components. The purpose of this brief review is to describe the properties of essential oils, principally as antifungal agents, and their role in blocking cell communication mechanisms, fungal biofilm formation, and mycotoxin production.

    EPA has agreed to establish a series of environmental standards for the safe disposal of radioactive waste through participation in the Interagency Review Group on Nuclear Waste Management (IRG). One of the standards required under the IRG is the standard for decommissioning of radioactive contaminated sites, facilities, and materials. This standard is to be proposed by December 1980 and promulgated by December 1981. Several considerations are important in establishing these standards. This study includes discussions of some of these considerations and attempts to evaluate their relative importance. Items covered include: the form of the standards, timing for decommissioning, occupational radiation protection, costs and financial provisions. 4 refs

    Indonesia is the source of raw essential oil in the world. Essential oils are used in various types of industries such as food and beverage, flavour, fragrance, perfumery, pharmaceuticals, and cosmetics. However, the development of Indonesian essential oil industry has not been encouraging for the production of essential oils, further it is unable to meet global demand. Besides that, the quality of volatile oil resulted cannot meet the international market standards. Based on the facts, the potential of Indonesian essential oils needs to be developed to provide added value, through increased production, improved quality and product diversification. One part of Indonesia having abundant of raw essential oil source is Central Java. Central Java has the quite large potential production of essential oils. Some essential oils produced from refining industry owned by the government, private and community sectors include cananga oils (Boyolali district), clove oils (Semarang district), patchouli oils (Brebes district, Pemalang district, and Klaten district). The main problem in the development of plants industries that producing essential oil in Central Java is low crops production, farming properties, quality of essential oils are diverse, providing poor-quality products and volatile oil price fluctuations. Marketing constraints of Central Java essential oils are quite complex supply chain. In general, marketing constraints of essential oils due to three factors, namely the low quality due to type of essential oil business that generally shaped small businesses with different capital and technology, domestic marketing is still a buyer-market (price determined by the buyer) because of weak bargaining position processors businessman, and prices fluctuate (domestic and foreign) due to uncontrolled domestic production and inter-country competition among manufacturers.

    To explore the perspectives of a diverse group of stakeholders engaged in medicines decision making around what constitutes an "essential" medicine, and how the Essential Medicines List (EML) concept functions in a high income country context. In-depth qualitative semi-structured interviews were conducted with 32 Australian stakeholders, recognised as decision makers, leaders or advisors in the area of medicines reimbursement or supply chain management. Participants were recruited from government, pharmaceutical industry, pharmaceutical wholesale/distribution companies, medicines non-profit organisations, academic health disciplines, hospitals, and consumer groups. Perspectives on the definition and application of the EML concept in a high income country context were thematically analysed using grounded theory approach. Stakeholders found it challenging to describe the EML concept in the Australian context because many perceived it was generally used in resource scarce settings. Stakeholders were unable to distinguish whether nationally reimbursed medicines were essential medicines in Australia. Despite frequent generic drug shortages and high prices paid by consumers, many struggled to describe how the EML concept applied to Australia. Instead, broad inclusion of consumer needs, such as rare and high cost medicines, and consumer involvement in the decision making process, has led to expansive lists of nationally subsidised medicines. Therefore, improved communication and coordination is needed around shared interests between stakeholders regarding how medicines are prioritised and guaranteed in the supply chain. This study showed that decision-making in Australia around reimbursement of medicines has strayed from the fundamental utilitarian concept of essential medicines. Many stakeholders involved in medicine reimbursement decisions and management of the supply chain did not consider the EML concept in their approach. The wide range of views of what stakeholders

    Agnihotri, Newal

    2003-01-01

    The article describes the benefits of and required process and recommendations for implementing the standardization of training in the nuclear power industry in the United States and abroad. Current Information and Communication Technologies (ICT) enable training standardization in the nuclear power industry. The delivery of training through the Internet, Intranet and video over IP will facilitate this standardization and bring multiple benefits to the nuclear power industry worldwide. As the amount of available qualified and experienced professionals decreases because of retirements and fewer nuclear engineering institutions, standardized training will help increase the number of available professionals in the industry. Technology will make it possible to use the experience of retired professionals who may be interested in working part-time from a remote location. Well-planned standardized training will prevent a fragmented approach among utilities, and it will save the industry considerable resources in the long run. It will also ensure cost-effective and safe nuclear power plant operation

    1974-07-01

    At the conference there was a considerable interest in research reactor standards and effluent standards in particular. On the program, this is demonstrated by the panel discussion on effluents, the paper on argon 41 measured by Sims, and the summary paper by Ringle, et al. on the activities of ANS research reactor standards committee (ANS-15). As a result, a meeting was organized to discuss the proposed ANS standard on research reactor effluents (15.9). This was held on Tuesday evening, was attended by members of the ANS-15 committee who were present at the conference, participants in the panel discussion on the subject, and others interested. Out of this meeting came a number of excellent suggestions for changes which will increase the utility of the standard, and a strong recommendation that the effluent standard (15.9) be combined with the effluent monitoring standard. It is expected that these suggestions and recommendations will be incorporated and a revised draft issued for comment early this summer. (author)

    This compilation of all nuclear standards available to the authors by mid 1980 represents the third, carefully revised edition of a catalogue which was first published in 1975 as EUR 5362. In this third edition several changes have been made. The title has been condensed. The information has again been carefully up-dated, covering all changes regarding status, withdrawal of old standards, new projects, amendments, revisions, splitting of standards into several parts, combination of several standards into one, etc., as available to the authors by mid 1980. The speed with which information travels varies and requires in many cases rather tedious and cumbersome inquiries. Also, the classification scheme has been revised with the goal of better adjustment to changing situations and priorities. Whenever it turned out to be difficult to attribute a standard to a single subject category, multiple listings in all relevant categories have been made. As in previous editions, within the subcategories the standards are arranged by organization (in Categorie 2.1 by country) alphabetically and in ascending numerical order. It covers all relevant areas of power reactors, the fuel cycle, radiation protection, etc., from the basic laws and governmental regulations, regulatory guides, etc., all the way to voluntary industrial standards and codes of pratice.

Patch test is the gold standard to identify the causative agent. Nowadays, there are many patch test standard materials available in the market, but do not include all the materials that potentially cause contact dermatitis. Patch test using patient’s own products or later we refer to as non-standard materials, is very helpful in identifying the causative agents of contact dermatitis. Guidance is needed in producing non-standard patch test materials in order to avoid test results discrepancy.

    Essentials of Radiation Heat Transfer is a textbook presenting the essential, fundamental information required to gain an understanding of radiation heat transfer and equips the reader with enough knowledge to be able to tackle more challenging problems. All concepts are reinforced by carefully chosen and fully worked examples, and exercise problems are provided at the end of every chapter. In a significant departure from other books on this subject, this book completely dispenses with the network method to solve problems of radiation heat transfer in surfaces. It instead presents the powerful radiosity-irradiation method and shows how this technique can be used to solve problems of radiation in enclosures made of one to any number of surfaces. The network method is not easily scalable. Secondly, the book introduces atmospheric radiation, which is now being considered as a potentially important area, in which engineers can contribute to the technology of remote sensing and atmospheric sciences in general, b...

    The MATE (Modular Automatic Test Equipment) program was developed to combat the proliferation of unique, expensive ATE within the Air Force. MATE incorporates a standard management approach and a standard architecture designed to implement a cradle-to-grave approach to the acquisition of ATE and to significantly reduce the life cycle cost of weapons systems support. These standards are detailed in the MATE Guides. The MATE Guides assist both the Air Force and Industry in implementing the MATE concept, and provide the necessary tools and guidance required for successful acquisition of ATE. The guides also provide the necessary specifications for industry to build MATE-qualifiable equipment. The MATE architecture provides standards for all key interfaces of an ATE system. The MATE approach to the acquisition and management of ATE has been jointly endorsed by the commanders of Air Force Systems Command and Air Force Logistics Command as the way of doing business in the future.

    1989-01-01

    The essential tools needed for the analysis of HEP experiments are software, networking, data handling, and CPU power. Leaving most software topics to other papers, this paper describes how we can use today's hardware effectively for HEP data analysis. It describes a new but viable model for HEP computing and data handling on a single site, and outlines the challenge of extending this environment to the wider university-based community. Finally it touches on the revolution in software design that may be triggered by the revolution in computing technology. (orig.)

    2006-01-01

    Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency.This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards

    Full Text Available Steven Okoli, Claire HarrisonDepartment of Haematology, Guy's and St Thomas' NHS Foundation Trust, Great Maze Pond, London, UKAbstract: In 1934, Epstein and Goedel used the term hemorrhagic thrombocythemia to describe a disorder characterized by permanent elevation of a platelet count to more than three times normal, hyperplasia of megakaryocytes, and the tendency for venous thrombosis and spontaneous hemorrhage. Over the last 75 years, and particularly in the past 6 years, major progress has been made in our understanding of essential thrombocythemia (ET and its pathogenesis with the identification of the highly prevalent JAK-2 V617F and other mutations. Current management of this condition is based upon historical data and with treatments that have not changed significantly for nearly two decades. This study discusses this and recent progress, highlighting exciting new data with old and new drugs, as well as which patients in particular should be evaluated for these new therapies.Keywords: essential thrombocythemia, interferon, JAK inhibitor

  1. Economic demand and essential value.

    Science.gov (United States)

    Hursh, Steven R; Silberberg, Alan

    2008-01-01

    The strength of a rat's eating reflex correlates with hunger level when strength is measured by the response frequency that precedes eating (B. F. Skinner, 1932a, 1932b). On the basis of this finding, Skinner argued response frequency could index reflex strength. Subsequent work documented difficulties with this notion because responding was affected not only by the strengthening properties of the reinforcer but also by the rate-shaping effects of the schedule. This article obviates this problem by measuring strength via methods from behavioral economics. This approach uses demand curves to map how reinforcer consumption changes with changes in the "price" different ratio schedules impose. An exponential equation is used to model these demand curves. The value of this exponential's rate constant is used to scale the strength or essential value of a reinforcer, independent of the scalar dimensions of the reinforcer. Essential value determines the consumption level to be expected at particular prices and the response level that will occur to support that consumption. This approach permits comparing reinforcers that differ in kind, contributing toward the goal of scaling reinforcer value. (c) 2008 APA, all rights reserved

  2. Essential Tremor: A Neurodegenerative Disease?

    2014-07-01

    Full Text Available Background: Essential tremor (ET is one of the most common neurological disorders among adults, and is the most common of the many tremor disorders. It has classically been viewed as a benign monosymptomatic condition, yet over the past decade, a growing body of evidence indicates that ET is a progressive condition that is clinically heterogeneous, as it may be associated with a spectrum of clinical features, with both motor and non‐motor elements. In this review, I will describe the most significant emerging milestones in research which, when taken together, suggest that ET is a neurodegenerative condition.Methods: A PubMed search conducted in June 2014 crossing the terms “essential tremor” (ET and “neurodegenerative” yielded 122 entries, 20 of which included the term “neurodegenerative” in the article title. This was supplemented by articles in the author's files that pertained to this topic.Results/Discussion: There is an open and active dialogue in the medical community as to whether ET is a neurodegenerative disease, with considerable evidence in favor of this. Specifically, ET is a progressive disorder of aging associated with neuronal loss (reduction in Purkinje cells as well as other post‐mortem changes that occur in traditional neurodegenerative disorders. Along with this, advanced neuroimaging techniques are now demonstrating distinct structural changes, several of which are consistent with neuronal loss, in patients with ET. However, further longitudinal clinical and neuroimaging longitudinal studies to assess progression are required.

    Wilkinson, Jenny M; Cavanagh, Heather M A

    2005-07-01

    To date, of the Australian essential oils, only tea tree (Melaleuca alternifolia) and Eucalyptus spp. have undergone extensive investigation. In this study a range of Australian essential oils, including those from Anethole anisata, Callistris glaucophyllia, Melaleuca spp. and Thyptomine calycina, were assayed for in vitro antibacterial activity. M. alternifolia was also included for comparison purposes. Activity was determined using standard disc diffusion assays with each oil assayed at 100%, 10% and 1% against five bacteria (Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa and Alcaligenes faecalis) and the yeast, Candida albicans. All bacteria, with the exception of Ps. aeruginosa, were susceptible to one or more of the essential oils at 100%, with only Eremophilia mitchelli inhibiting the growth of any bacteria at 1% (inhibition of Sal. typhimurium). Where multiple samples of a single oil variety were tested variability in activity profiles were noted. This suggests that different methods of preparation of essential oils, together with variability in plant chemical profiles has an impact on whether or not the essential oil is of use as an antimicrobial agent. These results show that essential oils from Australian plants may be valuable antimicrobial agents for use alone or incorporated into cosmetics, cleaning agents and pharmaceutical products.

  9. Beyond the standard model

    International Nuclear Information System (INIS)

    Altarelli, G.

    1987-01-01

    The standard model of particle interactions is a complete and relatively simple theoretical framework which describes all the observed fundamental forces. It consists of quantum chromodynamics (QCD) and of the electro-weak theory of Glashow, Salam and Weinberg. The former is the theory of colored quarks and gluons, which underlies the observed phenomena of strong interactions, the latter leads to a unified description of electromagnetism and of weak interactions. The inclusion of the classical Einstein theory of gravity completes the set of established basic knowledge. The standard model is in agreement with essentially all of the experimental information which is very rich by now. The recent discovery of the charged and neutral intermediate vector bosons of weak interactions at the expected masses has closed a really important chapter of particle physics. Never before the prediction of new particles was so neat and quantitatively precise. Yet the experimental proof of the standard model is not completed. For example, the hints of experimental evidence for the top quark at a mass ∼ 40 GeV have not yet been firmly established. The Higgs sector of the theory has not been tested at all. Beyond the realm of pure QED, even remaining within the electro-weak sector, the level of quantitative precision in testing the standard model does not exceed 5% or so. Furthermore, the standard model does not look as the ultimate theory. To a closer inspection a large class of fundamental questions emerges and one finds that a host of crucial problems are left open by the standard model

    The German Standards Institute (DIN Deutsches Institut fuer Normung, Berlin) is engaged in health physics standards development in the following committees. The Nuclear Standards Committee (NKe), which deals mainly with nuclear science and technology, the fuel cycle, and radiation protection techniques. The Radiology Standards Committee (FNR), whose responsibilities are traditionally the principles of radiation protection and dosimetry, applied medical dosimetry, and medical health physics. The German Electrotechnical Commission (DKE), which is concerned mostly with instrumentation standards. The Material Testing Committee (FNM), which is responsible for radiation protection in nonmedical radiography. The current body of over one hundred standards and draft standards was established to supplement the Federal German radiation protection legislation, because voluntary standards can deal in more detail with the specific practical problems. The number of standards is steadily expanding due to the vigorous efforts of about thirty working groups, consisting of essentially all leading German experts of this field. Work is supported by the industry and the Federal Government. A review of the present status and future plans, and of the international aspects with regard to European and world (ISO, etc.) standards will be presented

    The year 1999 has been a year of consolidation for EPCOR Utilities, uniting the the former brands of Edmonton Power, Aquaalta and Eltec under a new single brand, EPCOR, to provide Edmontonians with a safe, high quality and reliable essential service at competitive prices . The company is building for growth by augmenting its product line with natural gas and green power, accessing new capital, proceeding with new projects at various sites, creating EPCOR Power Development Corporation with an ambitious mandate to grow beyond the Utilities traditional service areas. In proof of that, EPCOR Water Services won a strategically important contract in Port Hardy, BC; EPCOR Technologies also has been involved in projects beyond Alberta. As a sign of confidence in the company, the City of Edmonton voted to retain ownership of the company in July. The Utility also managed to win national awards for both safety and environmental practices and is the first utility company to have all its generating plants meet ISO 14001 standards. During 2000 the company will tackle the evolution of industry restructuring , will explore more diverse financial structures to accommodate growth and the increase in demand for services to make sure that EPCOR will be a leading provider of electric power and natural gas services as the era of deregulated competitive electrical services in Alberta begins in 2001. This report provides details of the achievements of the company's business units in 1999, accompanied by a consolidated financial statement

  17. Performance Standards': Utility for Different Uses of Assessments

    Directory of Open Access Journals (Sweden)

    Robert L. Linn

    2003-09-01

    Full Text Available Performance standards are arguably one of the most controversial topics in educational measurement. There are uses of assessments such as licensure and certification where performance standards are essential. There are many other uses, however, where performance standards have been mandated or become the preferred method of reporting assessment results where the standards are not essential to the use. Distinctions between essential and nonessential uses of performance standards are discussed. It is argued that the insistence on reporting in terms of performance standards in situations where they are not essential has been more harmful than helpful. Variability in the definitions of proficient academic achievement by states for purposes of the No Child Left Behind Act of 2001 is discussed and it is argued that the variability is so great that characterizing achievement is meaningless. Illustrations of the great uncertainty in standards are provided.

    There are distinct laws guaranteeing the protection of workers in the social and medical field, but the protection of workers in the technical field is based on a simple, general clause relating to technical standards, i.e. to a confusing variety of regulations. The author therefore asks for DIN standards to be set up in order to achieve a consistent and uniform set of rules and regulations. He furthermore points out that it is up to the government to initiate appropriate procedures within the framework of constitutional law towards solving the essential problem, namely that of directly incorporating technical expert knowledge in legal provisions.

  19. Simplified propagation of standard uncertainties

    International Nuclear Information System (INIS)

    Shull, A.H.

    1997-01-01

    An essential part of any measurement control program is adequate knowledge of the uncertainties of the measurement system standards. Only with an estimate of the standards'' uncertainties can one determine if the standard is adequate for its intended use or can one calculate the total uncertainty of the measurement process. Purchased standards usually have estimates of uncertainty on their certificates. However, when standards are prepared and characterized by a laboratory, variance propagation is required to estimate the uncertainty of the standard. Traditional variance propagation typically involves tedious use of partial derivatives, unfriendly software and the availability of statistical expertise. As a result, the uncertainty of prepared standards is often not determined or determined incorrectly. For situations meeting stated assumptions, easier shortcut methods of estimation are now available which eliminate the need for partial derivatives and require only a spreadsheet or calculator. A system of simplifying the calculations by dividing into subgroups of absolute and relative uncertainties is utilized. These methods also incorporate the International Standards Organization (ISO) concepts for combining systematic and random uncertainties as published in their Guide to the Expression of Measurement Uncertainty. Details of the simplified methods and examples of their use are included in the paper

  20. Essentialism Promotes Children's Inter-ethnic Bias

    Directory of Open Access Journals (Sweden)

    Gil eDiesendruck

    2015-08-01

    Full Text Available The present study investigated the developmental foundation of the relation between social essentialism and attitudes. Forty-eight Jewish Israeli secular 6-year-olds were exposed to either a story emphasizing essentialism about ethnicity, or stories controlling for the salience of ethnicity or essentialism per se. After listening to a story, children’s attitudes were assessed in a drawing and in an IAT task. Compared to the control conditions, children in the ethnic essentialism condition drew a Jewish and an Arab character as farther apart from each other, and the Jewish character with a more positive affect than the Arab character. Moreover, boys in the ethnic essentialism condition manifested a stronger bias in the IAT. These findings reveal an early link between essentialism and inter-group attitudes.

    Kuroda, Y; Kakigi, R; Shibasaki, H

    1988-04-01

    We investigated the effect of arotinolol, a new peripherally acting beta-adrenergic blocker, in 15 patients with essential tremor. The patients received 30 mg per day of arotinolol for 8 weeks. Accelerometer readings showed a significant reduction in amplitude of postural tremor after treatment. Action tremor also improved to essentially the same degree as postural tremor. The present findings support the view that the therapeutic effect of beta-blockers in essential tremor is mediated by peripheral beta-adrenergic receptors.

  4. [Essentialism and typological thinking in biological systematics].

    Science.gov (United States)

    Vasil'eva, L N

    2003-01-01

    In biological literature, essentialism and typological thinking are believed to be incompatible with evolutionary ideas. At present, the same considerations underlay the claims to abandon the Linnaean hierarchy, or the fundamental classificatory structure rooted in essentialism. This paper suggests to reconsider the negative views of Plato's typology and Aristotle's essentialism following the narrow interpretations that have nothing to do with the classification of living beings. Plato's theory of 'ideas' (or 'forms') is the basis of classificatory theory; it provided such concepts as 'species', 'genus', 'essence', 'dichotomous division' but the development of this theory in the framework of moral and esthetic values could not be beneficial to biology. Aristotle's essentialism is more complicated and exists in two forms; one of these, or classificatory essentialism, is a modification of Plato's typology; another one, or organismal essentialism, represents the shift of 'essence' from the world of relations between objects to the realm of particular things, where the concept of essence lost its basic meaning. It is senseless to look for unreal 'type of an organism' ('essence of a thing') but precisely this kind of essentialism is attractive for biologists and philosophers. Organismal essentialism is the underlying basis of so-called 'individuality thesis' that is used as a weapon against classificatory essentialism. The same thesis is associated with an extensional vision of taxa that also explains the criticism of Linnaean hierarchy, while the latter is the intentional structure and the first tool suggested for the rank coordination of many unequal taxa.

    Full Text Available Essential oils and some of their oxygenated constituents are known to possess antimicrobial activity. In the last 30 years, there is a dramatic increase in the number of resistant microorganisms against available antimicrobials and a tendency towards natural products; consequently, scientists have been forced to discover new bioactive agents preferably from nature. As a result of this, so many antimicrobial screening works have been published on plant essential oils including miscellaneous screening methods and several microorganism strains. The aim of this study was to determine the MIC values of 65 monoterpenoids and 3 phenyl propanoids commonly found in essential oils, against 24 pathogenic bacteria and Candida strains, by using standard reference broth dilution methods (CLSI M7-A7 and M27-A2. According to broth microdilution test results, when compared with standard agents, monoterpene hydrocarbons generally showed weak antibacterial effects (>16 to 4 mg/mL where the oxygenated monoterpenes inhibited the microbial growth between the concentrations of 16 to 0,03 mg/mL. Generally, tested compounds demonstrated better inhibitory effects on Candida strains then the bacteria panel. The most effective microbial growth inhibitor constituents were determined as carvacrol, thymol, cumin alcohol, terpinen-4-ol, α-terpineol, lavandulol, estragol and thymoquinone.

    A constitutional guarantee of access to essential medicines has been identified as an important indicator of government commitment to the progressive realization of the right to the highest attainable standard of health. The objective of this study was to evaluate provisions on access to essential medicines in national constitutions, to identify comprehensive examples of constitutional text on medicines that can be used as a model for other countries, and to evaluate the evolution of constitutional medicines-related rights since 2008. Relevant articles were selected from an inventory of constitutional texts from WHO member states. References to states' legal obligations under international human rights law were evaluated. Twenty-two constitutions worldwide now oblige governments to protect and/or to fulfill accessibility of, availability of, and/or quality of medicines. Since 2008, state responsibilities to fulfill access to essential medicines have expanded in five constitutions, been maintained in four constitutions, and have regressed in one constitution. Government commitments to essential medicines are an important foundation of health system equity and are included increasingly in state constitutions.

    2015-01-01

    Full Text Available The field experiments were carried out during 2011 and 2012 in three localities in Vojvodina (Serbia with the application of six different fertilizer regimes aimed at determining the content and composition of the aniseed essential oil. It was found that the average essential oil content of aniseed, obtained by hydrodistillation, was 3.72%. The weather conditions during the year and the locality had a statistically significant effect on the essential oil content, while different source of fertilizers was not statistically significant for the essential oil content and its composition. Essential oil composition was determined using GC-MS technique, and a total of 15 compounds were identified. It was found that the major component was trans-anethole, 94.78% on the average, and the coefficient of variation was 2%. The second most abundant component was γ-himachalene with 2.53% (CV 28%. All other components were present in less than 1%.

    2018-06-01

    To raise awareness about the importance of public pharmaceutical standards, identify if and, if so, where current pharmacopeias are falling short in the development of new and complete monographs and foster collaboration among the various pharmacopeias, to prioritize, develop and make available standards for those key medicines for which no complete monographs exist. In August 2017, we mined eight pharmacopeias to identify which of the 669 medicines in the 20th edition of the World Health Organization's Model List of Essential Medicines were covered by complete or incomplete monographs. The pharmacopeias we included were the Brazilian Pharmacopoeia, the British Pharmacopoeia, the Indian Pharmacopeia Commission, the International Pharmacopoeia, the Japanese Pharmacopoeia, the Mexican Pharmacopoeia, the Pharmacopeia of the People's Republic of China and the United States Pharmacopeia. For 99 (15%) of the medicines on the Model List, no monographs were available in any of the eight pharmacopeias investigated. Only 3% (1/30) of the cardiovascular medicines listed, but 28% (9/32) of the antiretroviral medicines and 23% (6/26) of the antimalarial medicines lacked monographs. There appear to be no public standards for many so-called essential medicines. To address this shortfall, a greater collaboration in the global health community is needed.

    Pedro Raymundo Argüelles Osorio

    2018-03-01

    Full Text Available ABSTRACT The objectives of this study were to evaluate the effect of lemon grass, citronella grass, Mexican-tea and noni essential oils on urediniospore germination of Olivea neotectonae , the agent responsible for rust in Teak (Tectona grandis L.f.; to evaluate the phytotoxic effect of these essential oils on teak seedlings; and to evaluate the use of essential oils to control rust in teak plants when preventively and curatively applied. We found that the noni and lemon grass essential oils inhibited 100% of urediniospore germination. On the other hand, the essential oils from noni and lemon grass caused phytotoxicity when applied to seedlings at concentrations of 2000 and 1500 μL L-1, respectively. The major constituents found in lemon grass essential oil were Geranial and Neral, while Octanoic Acid was found in noni oil. Lower values in the area below the rust progress curve were observed with the preventive application of lemon grass and noni essential oils.

    2013-01-01

    Full Text Available Essential thrombocythemia is an acquired myeloproliferative disorder characterized by the proliferation of megakaryocytes in bone marrow, leading to a persistent increase in the number of circulating platelets and thus increasing the risk for thrombotic and hemorrhagic events. The disease features leukocytosis, splenomegaly, vascular occlusive events, hemorrhages and vasomotor disorders. The intricate mechanisms underlying the molecular pathogenesis of this disorder are not completely understood and are still a matter of discussion. Essential thrombocythemia is an extremely rare disorder during childhood. We report on a case of essential thrombocythemia in a child and discuss the diagnostic approach and treatment strategy.

    2011-01-01

    The present study was conducted to investigate the antioxidant and radical scavenging activities of essential oils of four Lamiaceae plants i.e. Pogostemon cablin, Lavandula angustifolia, Melissa officinalis, and Salvia officinalis native to Pakistan. The essential oil contents from the aerial parts of P. cablin, L. angustifolia, M. officinalis and S. officinalis were found to be 1.98, 0.58, 0.25 and 0.46%, respectively. The principal chemical constituent established in P. cablin L. angustifolia, M. officinalis, and S. officinalis essential oils, were patchouli alcohol, linalool, citronellal, and 1,8-cineol, respectively. The antioxidant activity was evaluated by scavenging of 2,2-diphenyl-1-picryl hydrazyl radical (DPPH), percent inhibition of linoleic acid oxidation and bleaching beta-carotene in linoleic acid system. The essential oils possessed appreciable antioxidant and radical scavenging activities revealing potential for therapeutic applications. (author)

  3. Dosimetry standards for radiation processing

    International Nuclear Information System (INIS)

    Farrar, H. IV

    1999-01-01

    For irradiation treatments to be reproducible in the laboratory and then in the commercial environment, and for products to have certified absorbed doses, standardized dosimetry techniques are needed. This need is being satisfied by standards being developed by experts from around the world under the auspices of Subcommittee E10.01 of the American Society for Testing and Materials (ASTM). In the time period since it was formed in 1984, the subcommittee has grown to 150 members from 43 countries, representing a broad cross-section of industry, government and university interests. With cooperation from other international organizations, it has taken the combined part-time effort of all these people more than 13 years to complete 24 dosimetry standards. Four are specifically for food irradiation or agricultural applications, but the majority apply to all forms of gamma, x-ray, Bremsstrahlung and electron beam radiation processing, including dosimetry for sterilization of health care products and the radiation processing of fruits, vegetables, meats, spices, processed foods, plastics, inks, medical wastes and paper. An additional 6 standards are under development. Most of the standards provide exact procedures for using individual dosimetry systems or for characterizing various types of irradiation facilities, but one covers the selection and calibration of dosimetry systems, and another covers the treatment of uncertainties. Together, this set of standards covers essentially all aspects of dosimetry for radiation processing. The first 20 of these standards have been adopted in their present form by the International Organization of Standardization (ISO), and will be published by ISO in 1999. (author)

  4. Postharvest quality of essential oil treated roses

    Directory of Open Access Journals (Sweden)

    Guilherme Mariano Manfredini

    2017-07-01

    Full Text Available The loss of commercial quality during storage and transportation of roses is one of the factors that reflect on production costs, leading producers to preventively apply harmful chemicals, mainly to hamper Botrytis cinerea development and reduce further losses. An alternative to increase flower longevity without contaminating the environment with harmful chemicals is the use of natural products, such as essential oils, which have fungistatic and insecticide properties, as well as low toxicity. The objective of this study was to evaluate the effect of essential oils on the vase life of Rosa cv. Avalanche: 12 treatments were tested, resulting from the combination of 5 types of essential oils plus the control in two cold storage periods (2 to 6 days at 1 °C, 90-95% RH. The essential oils tested were eucalyptus, cinnamon, lemongrass and peppermint (1%, clove (0.1%, plus a control with distilled water. Application was made by spraying the flower buds. After storage at low temperatures, the flower stems were kept in a room (16 °C, 70% RH during 10 days for evaluation. Flower stems stored for 2 days in a cold chamber showed better means for darkening, turgor and bent neck, as well as a lower weight loss by the stems. The application of lemongrass essential oil at 1% caused burns on the petals, compromising quality and pot life. The essential oils of peppermint and eucalyptus allowed flower quality maintenance until the 10th day of evaluation. It is possible to conclude that post-harvest spraying with peppermint or eucalyptus essential oil at 1%, combined with cold storage for 2 days, provided greater longevity and quality for cv. Avalanche roses.

  6. A Systematic Review of the Anxiolytic-Like Effects of Essential Oils in Animal Models

    Directory of Open Access Journals (Sweden)

    Damião Pergentino de Sousa

    2015-10-01

    Full Text Available The clinical efficacy of standardized essential oils (such as Lavender officinalis, in treating anxiety disorders strongly suggests that these natural products are an important candidate source for new anxiolytic drugs. A systematic review of essential oils, their bioactive constituents, and anxiolytic-like activity is conducted. The essential oil with the best profile is Lavendula angustifolia, which has already been tested in controlled clinical trials with positive results. Citrus aurantium using different routes of administration also showed significant effects in several animal models, and was corroborated by different research groups. Other promising essential oils are Citrus sinensis and bergamot oil, which showed certain clinical anxiolytic actions; along with Achillea wilhemsii, Alpinia zerumbet, Citrus aurantium, and Spiranthera odoratissima, which, like Lavendula angustifolia, appear to exert anxiolytic-like effects without GABA/benzodiazepine activity, thus differing in their mechanisms of action from the benzodiazepines. The anxiolytic activity of 25 compounds commonly found in essential oils is also discussed.

    2015-01-01

    The aim was to determine the proportions and correlates of essential hypertension among children in a tertiary pediatric hypertension clinic. We evaluated 423 consecutive children and collected demographic and clinical history by retrospective chart review. We identified 275 (65%) hypertensive children (blood pressure >95th percentile per the "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents") from 423 children referred to the clinic for history of elevated blood pressure. The remainder of the patients had normotension (11%), white coat hypertension (11%), prehypertension (10%), and pending diagnosis (3%). Among the 275 hypertensive children, 43% (n = 119; boys = 56%; median age = 12 years; range = 3-17 years) had essential hypertension and 57% (n = 156; boys = 66%; median age = 9 years; range = 0.08-19 years) had secondary hypertension. When compared with those with secondary hypertension, those with essential hypertension had a significantly older age at diagnosis (P = 0.0002), stronger family history of hypertension (94% vs. 68%; P secondary hypertension. The phenotype of essential hypertension can present as early as 3 years of age and is the predominant form of hypertension in children after age of 6 years. Among children with hypertension, those with essential hypertension present at an older age, have a stronger family history of hypertension, and have lower prevalence of preterm birth. © American Journal of Hypertension, Ltd 2014.

    2013-12-01

    Haiti is the poorest country in the Western Hemisphere and faces numerous challenges, including inadequate medication access for its residents. The objective of this study was to determine the availability, prices, and affordability of essential medicines in Haiti and compare these findings to other countries. We conducted a cross-sectional nationwide survey in 2011 of availability and consumer prices of 60 essential medicines in Haiti using a standardized methodology developed by the World Health Organization and Health Action International. The survey was conducted in 163 medicine outlets in four health care sectors (public, retail, nonprofit and mixed sectors). Medicine prices were expressed as ratios relative to the International Reference Price. Affordability was calculated by comparing the costs of treatment for common conditions with the salary of the lowest paid government worker and was compared to available data from four Latin American countries. For generic medicines, the availability in public, retail, nonprofit and mixed sectors was 20%, 37%, 24% and 23% of medications, respectively. Most of the available medicines were priced higher than the International Reference Price. The lowest paid government worker would need 2.5 days' wages to treat an adult respiratory infection with generic medicines from the public sector. For treatment of common conditions with originator brands (OB) purchased from a retail pharmacy, costs were between 1.4 (anaerobic bacterial infection) and 13.7 (hyperlipidemia) days' wages, respectively. Treatment of pediatric bacterial infections with the OB of ceftriaxone from a retail pharmacy would cost 24.6 days' wages. Prices in Bolivia, Colombia, Mexico and Nicaragua were frequently lower for comparable medications. The availability of essential medicines was low and prices varied widely across all four sectors. Over 75% of Haitians live on less than US$ 2.00 /day; therefore, most medication regimens are largely unaffordable

    2016-03-01

    The purposes of this study were to evaluate the distribution pattern and population size of Malassezia species in dogs with atopic dermatitis (AD) and the inhibitory efficacy of Zataria multiflora, Thymus kotschyanus, Mentha spicata, Artemisia sieberi, Rosmarinus officinalis and Heracleum persicum essential oils against pathogenic Malassezia isolates. The samples were collected from 5 different anatomical sites of 33 atopic dogs and cultured onto modified Dixon agar (MDA) and Sabouraud dextrose agar (SDA) media. The essential oil extraction was performed by steam distillation using Clevenger system. Anti-Malassezia efficacy of medicinal essential oils and standard drugs was evaluated using broth microdilution method. A total of 103 yeast colonies were isolated from dogs with AD. Eight different Malassezia species were identified as follows: Malassezia pachydermatis (81.4%), M. globosa (7.8%), M. restricta (3.9%), M. sloofiae (2.9%), M. furfur (1%), M. nana (1%), M. obtusa (1%) and M. sympodialis (1%). The most and least infected sites were: anal (21.2%) and ear (10.6%) respectively. M. pachydermatis was the most frequent Malassezia species isolated from both skin and mucosa of dogs with AD. Antifungal susceptibility test revealed the inhibitory efficacy of essential oils on pathogenic Malassezia isolates with minimum inhibitory concentration (MIC(90)) values ranging from 30 to 850 μg/mL. Among the tested oils, Z. multiflora and T. kotschyanus exhibited the highest inhibitory effects (Pessential oils of Z. multiflora and T. kotschyanus showed strong antifungal activity against pathogenic Malassezia species tested.

  15. Ratings of Essentialism for Eight Religious Identities.

    Science.gov (United States)

    Toosi, Negin R; Ambady, Nalini

    2011-01-01

    As a social identity, religion is unique because it contains a spectrum of choice. In some religious communities, individuals are considered members by virtue of having parents of that background, and religion, culture, and ethnicity are closely intertwined. Other faith communities actively invite people of other backgrounds to join, expecting individuals to choose the religion that best fits their personal beliefs. These various methods of identification influence beliefs about the essentialist nature of religious identity. Essentialism is when social groups are considered to have deep, immutable, and inherent defining properties. In this study, college students (N=55) provided ratings of essentialism for eight religious identities: Atheist, Buddhist, Catholic, Hindu, Jewish, Muslim, Protestant, and Spiritual-but-not-religious. Significant differences in essentialism were found between the target groups. Results and implications for intergroup relations are discussed.

  16. Project Management: Essential Skill of Nurse Informaticists.

    Science.gov (United States)

    Sipes, Carolyn

    2016-01-01

    With the evolution of nursing informatics (NI), the list of skills has advanced from the original definition that included 21 competencies to 168 basic competencies identified in the TIGER-based Assessment of Nursing Informatics Competencies (TANIC) and 178 advanced skills in the Nursing Informatics Competency Assessment (NICA) L3/L4 developed by Chamberlain College of Nursing, Nursing Informatics Research Team (NIRT). Of these competencies, project management is one of the most important essentials identified since it impacts all areas of NI skills and provides an organizing framework for processes and projects including skills such as design, planning, implementation, follow-up and evaluation.

    2015-12-21

    Enterococci are able to survive endodontic procedures and contribute to the failure of endodontic therapy. Thus, it is essential to identify novel ways of eradicating them from infected root canals. One such approach may be the use of antimicrobials such as plant essential oils. Enterococcal strains were isolated from endodontically treated teeth by standard microbiological methods. Susceptibility to antibiotics was evaluated by the disc-diffusion method. The minimal inhibitory concentration (MIC) of geranium essential oil was investigated by microdilution in 96-well microplates in Mueller Hinton Broth II. Biofilm eradication concentrations were checked in dentin tests. Geranium essential oil inhibited enterococcal strains at concentrations ranging from 1.8-4.5 mg/mL. No correlation was shown between resistance to antibiotics and the MICs of the test antimicrobials. The MICs of the test oil were lower than those found to show cytotoxic effects on the HMEC-1 cell line. Geranium essential oil eradicated enterococcal biofilm at concentrations of 150 mg/mL. Geranium essential oil inhibits the growth of endodontic enterococcal species at lower concentrations than those required to reach IC50 against the HMEC-1 cell line, and is effective against bacteria protected in biofilm at higher concentrations. In addition, bacteria do not develop resistance to essential oils. Hence, geranium essential oil represents a possible alternative to other antimicrobials during endodontic procedures.

  6. The Determination of Essentiality as a Leading Principle of the Formation of Integrated Reporting

    Directory of Open Access Journals (Sweden)

    Makarenko Vita Yu.

    2018-03-01

    Full Text Available The definition of essentiality as the leading principle of formation of integrated reporting is considered. The normative basis of essentiality in the context of integrated reporting is the International standard for integrated reporting. The principle of essentiality is that the integrated report should disclose information on issues that have a significant impact on an assessment of the organization’s ability to generate value in the short, medium, and long term periods. Essential for an integrated report is information that is capable of making changes to the organization’s value creation procedure. The definition of essentiality indicates that the essential information is the one that can change the order of assessment of any particular event. Therefore, insignificant for the integrated report is the information that cannot and does not bring such changes. The lack of a clear methodology for determining the essentiality, on the one hand, facilitates application of the principle of essentiality in specific conditions, and on the other — reduces the comparability of indicators of integrated reporting.

    Snell, R.O.

    1994-01-01

    The International Standards Organisation has initiated a program to develop a suite of ISO Codes and Standards for the Oil Industry. The Offshore Structures Standard is one of seven topics being addressed. The scope of the standard will encompass fixed steel and concrete structures, floating structures, Arctic structures and the site specific assessment of mobile drilling and accommodation units. The standard will use as base documents the existing recommended practices and standards most frequently used for each type of structure, and will develop them to incorporate best published and recognized practice and knowledge where it provides a significant improvement on the base document. Work on the Code has commenced under the direction of an internationally constituted sub-committee comprising representatives from most of the countries with a substantial offshore oil and gas industry. This paper outlines the background to the code and the format, content and work program

  12. Productivity standards for histology laboratories.

    Science.gov (United States)

    Buesa, René J

    2010-04-01

    The information from 221 US histology laboratories (histolabs) and 104 from 24 other countries with workloads from 600 to 116 000 cases per year was used to calculate productivity standards for 23 technical and 27 nontechnical tasks and for 4 types of work flow indicators. The sample includes 254 human, 40 forensic, and 31 veterinary pathology services. Statistical analyses demonstrate that most productivity standards are not different between services or worldwide. The total workload for the US human pathology histolabs averaged 26 061 cases per year, with 54% between 10 000 and less than 30 000. The total workload for 70% of the histolabs from other countries was less than 20 000, with an average of 15 226 cases per year. The fundamental manual technical tasks in the histolab and their productivity standards are as follows: grossing (14 cases per hour), cassetting (54 cassettes per hour), embedding (50 blocks per hour), and cutting (24 blocks per hour). All the other tasks, each with their own productivity standards, can be completed by auxiliary staff or using automatic instruments. Depending on the level of automation of the histolab, all the tasks derived from a workload of 25 cases will require 15.8 to 17.7 hours of work completed by 2.4 to 2.7 employees with 18% of their working time not directly dedicated to the production of diagnostic slides. This article explains how to extrapolate this productivity calculation for any workload and different levels of automation. The overall performance standard for all the tasks, including 8 hours for automated tissue processing, is 3.2 to 3.5 blocks per hour; and its best indicator is the value of the gross work flow productivity that is essentially dependent on how the work is organized. This article also includes productivity standards for forensic and veterinary histolabs, but the staffing benchmarks for histolabs will be the subject of a separate article.

  17. Tapping generalized essentialism to predict outgroup prejudices.

    Science.gov (United States)

    Hodson, Gordon; Skorska, Malvina N

    2015-06-01

    Psychological essentialism, the perception that groups possess inherent properties binding them and differentiating them from others, is theoretically relevant to predicting prejudice. Recent developments isolate two key dimensions: essentialistic entitativity (EE; groups as unitary, whole, entity-like) and essentialistic naturalness (EN; groups as fixed and immutable). We introduce a novel question: does tapping the covariance between EE and EN, rather than pitting them against each other, boost prejudice prediction? In Study 1 (re-analysis of Roets & Van Hiel, 2011b, Samples 1-3, in Belgium) and Study 2 (new Canadian data) their common/shared variance, modelled as generalized essentialism, doubles the predictive power relative to regression-based approaches with regard to racism (but not anti-gay or -schizophrenic prejudices). Theoretical implications are discussed. © 2014 The British Psychological Society.

  18. Essential Requirements for Digital Annotation Systems

    Directory of Open Access Journals (Sweden)

    ADRIANO, C. M.

    2012-06-01

    Full Text Available Digital annotation systems are usually based on partial scenarios and arbitrary requirements. Accidental and essential characteristics are usually mixed in non explicit models. Documents and annotations are linked together accidentally according to the current technology, allowing for the development of disposable prototypes, but not to the support of non-functional requirements such as extensibility, robustness and interactivity. In this paper we perform a careful analysis on the concept of annotation, studying the scenarios supported by digital annotation tools. We also derived essential requirements based on a classification of annotation systems applied to existing tools. The analysis performed and the proposed classification can be applied and extended to other type of collaborative systems.

  19. MODALITY OF TREATMENT IN ESSENTIAL THROMBOCYTHEMIA

    Directory of Open Access Journals (Sweden)

    Lana Macukanovic-Golubovic

    2008-10-01

    Full Text Available Essential thrombocytosis (ET is clonal chronic myeloproliferative disorder which originates from abnormality of a multipotent hematopoietic stem cell.It is characterized by an increased platelet count, megakaryocytic hyperplasia and by hemorrhagic or thrombotic tendency. Symptoms and signs may include weakness, headaches, paresthesias, bleeding, splenomegaly, and digital ischemia. ET patients showed equal or slightly shorter survival than age- and sex-matched healthy population. Major causes of death were thrombotic and hemorrhagic complications or malignant progression due to both the natural history of the disease and, possibly, the use of chemotherapeutic agents.Diagnostic criteria for essential thrombocythemia were proposed in 2005 by the PVSG and demand diagnosis of exclusion.Myelosuppressive therapy to lower the platelet count usually consists of hydroxyurea, interferon alpha or anagrelide. Hydroxyurea is the most commonly used treatment, because of its efficacy, low cost and rare acute toxicity. Interferon alpha is a biological response modifier. It is not known to be teratogenic and does not cross the placenta, and is often the treatment of choice during pregnancy. Anagrelid suppresses bone marrow megakaryocytes by interfering with the maturation process and decreasing platelet production without affecting other blood cell lines. Low-dose aspirin may be used to control microvascular symptoms.Recommendations for management of patients with essential thrombocythemia were given by ASH. From a treatment standpoint, hydroxyurea is now confirmed to be the drug of choice for high-risk patients with essential thrombocythemia. Interferon alpha and anagrelide are reasonable second-line agents. Low-risk patients should receive low-dose aspirin alone. For the intermediate-risk patients, a consensus could not be reached on a recommendation for platelet-lowering treatment.

I have also created the concept called the Essential Understanding of Creative Writing, which I think is the base and the starting point of teaching creative writing. The term is hypothesis and it roughly means the subjectively understood essence of creative work and writing process, as well as the strengthening the inner motivation and author identity by writer. Collaboration seems to support the E...

    Holdup measurement, needed for material balance, depend intensively on standards and on interpretation of the calibration procedure. More than other measurements, the calibration procedure using the standard becomes part of the standard. Standards practical for field use and calibration techniques have been developed. While accuracy in holdup measurements is comparatively poor, avoidance of bias is a necessary goal

    To evaluate fundus autofluorescence (FAF) changes in patients with chronic essential hypertension (HTN). In this case-control study, 35 eyes of 35 patients with chronic essential HTN (lasting >5 years) and 31 eyes of 31 volunteers without history of HTN were included. FAF pictures were taken from right eyes of all cases with the Heidelberg retina angiography and then were assessed by two masked retinal specialists. In total, FAF images including 35 images of hypertensive patients and 31 pictures of volunteers, three apparently abnormal patterns were detected. A ring of hyper-autofluorescence in the central macula (doughnut-shaped) was observed in 9 (25.7%) eyes of the hypertensive group but only in 2 (6.5%) eyes of the control group. This difference was statistically significant (P = 0.036) between two groups. Hypo- and/or hyper-autofluorescence patches outside the fovea were the other sign found more in the hypertensive group (22.9%) than in the control group (6.5%); however, the difference was not statistically significant (P = 0.089). The third feature was hypo-autofluorescence around the disk noticed in 11 (31.4%) eyes of hypertensive patients compared to 8 (25.8%) eyes of the controls (P = 0.615). A ring of hyper-autofluorescence in the central macula forming a doughnut-shaped feature may be a FAF sign in patients with chronic essential HTN.

    This annual report provides details of the financial operations of EPCOR, the newly formed utility, combining together three essential elements of modern living --electric power, water and natural gas-- as a single entity. In addition to this report on financial management, there are two companion reports on environmental performance entitled {sup E}ssential Balance', and on contributions to the community with the title of 'Essential Spirit'. While this report focuses on the Corporation's financial performance, it also provides a summary on the Corporation's growth, operational excellence, regulatory matters, environmental achievements and management of the Corporation's people resources. The financial report includes the customary consolidated financial statements, the auditor's report, and management's discussion and analysis of the financial report. Revenues for 1999 totalled just over one billion dollars ($978 million in 1998); net income was $116 million ($121 million in 1998); operating expenses were higher than in 1998 ($765 million versus $642 million) due to higher natural gas prices; capital spending was $198 million, compared to $153 million in 1998. Operations, maintenance, and administrative costs were also higher in 1999 due to higher employee costs across the EPCOR Group, one-time costs associated with EPCOR's master branding initiative, Y2K testing and remediation, and increased business development costs.

    The Delhi State Drug Policy was adopted in 1994 following which the first Essential Medicines List (EML) was developed in 1996. The Delhi State Essential Medicines Formulary was brought out in 1997. A need was felt to revise the formulary to match with the EML as the EML is renewed every 2 years. A survey was undertaken to elicit the opinions of the doctors practicing in the state on the usefulness of the formulary before revising and printing the updated version. The survey covered dispensaries, 10-20 bedded hospitals, 100-bedded hospitals and two tertiary care hospitals. Discussions were focused on questionnaires on attitudes toward adopting Essential Medicines Formulary using a 10-point scale. Of the 200 doctors approached, only 90 doctors completed the questionnaire. Sixty-nine respondents (76.6%) had received the copy of the formulary. Most practitioners welcomed the formulary and were satisfied with the coverage and selection of the medicines. Most respondents (76.9%) agreed that a well-developed formulary would improve the quality of the public health care system, although they had reservations about the authority, relevance and effect on professional autonomy. About 74% of the respondents used the formulary in clinical practice as a source of medicine information, which makes its regular revision necessary.

    Full Text Available Background and objectives: Helichrysum oligocephalum DC. (Compositae  is an endemic plant in Iran that has been recommended by Iranian traditional and folk medicine practitioners for gastrointestinal complaints. The plant is rich in essential oil and in the present investigation, the volatile composition of the species has been determined. Methods: The light yellow essential oil from the aerial parts of the plant was prepared according to the method which was recommended in British Pharmacopoeia by using hydrodistillation. The chemical composition of the oil was investigated by gas chromatography mass spectroscopy (GC/MS. Results: Thirty-seven compounds were identified; among them β-caryophyllene, α-humulene and epimanoyl oxide were dominant. Sesquiterpenoids were the most dominant compounds in the essential oil while monoterpenoides, fatty acids and diterpenoides were found to be less. These outcomes are a little bit different from what has been reported before. Conclusion: The differences between the results of the present study with previous works could be due to the diversity of variety, polymorphism, stage of plant growth and environmental factors.

    Full Text Available Herbal essential oils are volatile, natural, complex compounds formed by medicinal plants as secondary metabolites. As reported by international organization for standardization (ISO, the term "essential oils" (EOs is defined for a product obtained from vegetable raw materials or fruit using distillation with water or steam. The EOs are generally complex mixtures of volatile organic compounds include hydrocarbons (terpenes and sesquiterpenes and oxygenated compounds (alcohols, esters, ethers, aldehydes, ketones, lactones, phenols, and phenol ethers compounds. In medicinal plants, the EOs chemical profile usually very varies because of both intrinsic (sexual, seasonal, ontogenetic, and genetic variations and extrinsic (ecological and environmental aspects factors, also the EOs composition differs not only in the number and type of molecules but also in their stereochemical structures, and can be very different according to the extraction method. EOs represents a “green” alternative in the nutritional and pharmaceutical fields due to reported antimicrobial, antioxidant, anti-inflammatory and anticancer properties thus, in recent times; EOs has gained great popularity as consumers have developed a particular ever-growing awareness toward the use of natural ingredients, especially in food and household. Therefore, the present review provides a comprehensive summary on the method of preparation of EOs from medicinal plants, chemical composition analysis, their biological and pharmacological effects and their potential benefits on health level. Present information was compiled using keywords “Essential oil, Medicinal Plants and Natural additive in scientific database as Science Direct, Elsevier, PubMed, Google scholar and SID, until 2005 to 2015. EOs have great antimicrobial activity and mostly destroy bacteria, fungi and viruses without harmful effects on consumer’s health. Finding of this study showed that the Thymol, α-Pinene,

    2010-03-01

    Full Text Available Aristotelian ethics is still very promising, mainly because of its meta-ethical naturalism. As in medicine, what’s good versus bad is based on knowledge of the nature of something. With the addition of a strong doctrine of voluntary action, the morally good life is one within which one pursues one’s human flourishing (by means of practicing the virtues. An obstacle is Aristotle’s essentialism whereby he stresses what is distinctive about human beings, not what is a matter of their nature, as the standard of right versus wrong conduct. If this is amended in Aristotle what emerges is what some have called a genuine naturalist, biocentric ethical eudaimonism. Here I sketch the case for this amended Aristotelian ethical view.

    The examination of skeletal remains is a challenge to the medical examiner's/coroner's office and the forensic anthropologist conducting the investigation. One of the objectives of the medico-legal investigation is to estimate stature or height from various skeletal remains and body parts brought for examination. Various skeletal remains and body parts bear a positive and linear correlation with stature and have been successfully used for stature estimation. This concept is utilized in estimation of stature in forensic anthropology casework in mass disasters and other forensic examinations. Scientists have long been involved in standardizing the anthropological data with respect to various populations of the world. This review deals with some essential methodological issues that need to be addressed in research related to estimation of stature in forensic examinations. These issues have direct relevance in the identification of commingled or unknown remains and therefore it is essential that forensic nurses are familiar with the theories and techniques used in forensic anthropology. © 2012 International Association of Forensic Nurses.

  18. Technology in Paralympic sport: performance enhancement or essential for performance?

    2010-02-01

    People with disabilities often depend on assistive devices to enable activities of daily living as well as to compete in sport. Technological developments in sport can be controversial. To review, identify and describe current technological developments in assistive devices used in the summer Paralympic Games; and to prepare for the London 2012 Games, the future challenges and the role of technology are debated. A systematic review of the peer-reviewed literature and personal observations of technological developments at the Athens (2004) and Beijing (2008) Paralympic Games was conducted. Standard assistive devices can inhibit the Paralympians' abilities to perform the strenuous activities of their sports. Although many Paralympic sports only require technology similar to their Olympic counterparts, several unique technological modifications have been made in prosthetic and wheelchair devices. Technology is essential for the Paralympic athlete, and the potential technological advantage for a Paralympian, when competing against an Olympian, is unclear. Technology must match the individual requirements of the athlete with the sport in order for Paralympians to safely maximise their performance. Within the 'performance enhancement or essential for performance?' debate, any potential increase in mechanical performance from an assistive device must be considered holistically with the compensatory consequences the disability creates. To avoid potential technology controversies at the 2012 London Olympic and Paralympic Games, the role of technology in sport must be clarified.

    The aim of present study was to develop and evaluate nanoemulsion formulations of clove essential oil (CEO) for its antibacterial effects in comparison with pure CEO and standard amikacin antibiotic (positive control). Different nanoemulsions of CEO were developed by aqueous phase titration method via construction of pseudo-ternary phase diagrams and investigated for thermodynamic stability and self-nanoemulsification tests. Selected formulations (F1-F5) were characterized for droplet size distribution, viscosity, zeta potential, transmittance and surface morphology. Based on lowest droplet size (29.1 nm), lowest PI (0.026), lowest viscosity (34.6 cp), optimal zeta potential (-31.4 mV), highest transmittance (99.4 %) and lowest concentration of Triacetin (8 % w/w), CEO nanoemulsion F1 (containing 1 % w/w of CEO, 8 % w/w of Triacetin, 15 % w/w of Tween-80, 15 % w/w of Labrasol and 61 % w/w of water) was subjected to antibacterial studies in comparison with pure oil and standard amikacin. The antibacterial effects of F1 were found to be superior over pure oil against all bacterial strains investigated. However, the antibacterial effects of F1 were highly comparable with standard amikacin against all bacterial strains. The minimum inhibitory concentrations (MICs) of F1 were observed in the range of 0.075-0.300 % w/w as compared to pure oil (MICs 0.130-0.500 % w/w) and standard amikacin (MICs 2-16 μg/ml). These results indicated the potential of nanoemulsions for enhancing the therapeutic efficacy of natural bioactive ingredients such as CEO.

    This paper describes the role of the World Organisation for Animal Health (OIE), as a science-based and democratic standard-setting organisation that provides guidance on preventing the spread of animal diseases, including zoonoses, in international trade. The World Trade Organization is identified as the international institution with the legal power to encourage adherence to international standards and mediate trade disputes. The importance of assuring good governance and the credibility of national Veterinary Services through a process of official certification is identified as an essential component in the safety of trade. Private-public partnerships and the evolution of responsibilities are also identified as essential for the implementation of health guarantees such as compartmentalisation. The rapid emergence of private standards is described as a potential complement to the implementation of sanitary standards, as long as they are applied globally and in support of the OIE standards. Ultimately, the biggest challenge is for the international community to create the incentives and generate the political will for fair trade and for the universal recognition and application of the established international sanitary standards.

    Essential tremor is a highly prevalent movement disorder characterized by kinetic tremor and mild cognitive-executive changes. These features are commonly attributed to abnormal cerebellar changes, resulting in disruption of cerebellar-thalamo-cortical networks. Less attention has been paid to alterations in basic emotion processing in essential tremor, despite known cerebellar-limbic interconnectivity. In the current study, we tested the hypothesis that a psychophysiologic index of emotional reactivity, the emotion modulated startle reflex, would be muted in individuals with essential tremor relative to controls. Participants included 19 essential tremor patients and 18 controls, who viewed standard sets of unpleasant, pleasant, and neutral pictures for six seconds each. During picture viewing, white noise bursts were binaurally presented to elicit startle eyeblinks measured over the orbicularis oculi. Consistent with past literature, controls' startle eyeblink responses were modulated according to picture valence (unpleasant > neutral > pleasant). In essential tremor participants, startle eyeblinks were not modulated by emotion. This modulation failure was not due to medication effects, nor was it due to abnormal appraisal of emotional picture content. Neuroanatomically, it remains unclear whether diminished startle modulation in essential tremor is secondary to aberrant cerebellar input to the amygdala, which is involved in priming the startle response in emotional contexts, or due to more direct disruption between the cerebellum and brainstem startle circuitry. If the former is correct, these findings may be the first to reveal dysregulation of emotional networks in essential tremor. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Essential plants, due to their long presence in human history, their status in culinary arts, their use in medicine and perfume manufacture, belong to frequently examined stock materials in scientific and industrial laboratories. Because of a large number of freshly cut, dried or frozen plant samples requiring the determination of essential oil amount and composition, a fast, safe, simple, efficient and highly automatic sample preparation method is needed. Five sample preparation methods (steam distillation, extraction in the Soxhlet apparatus, supercritical fluid extraction, solid phase microextraction and pressurized liquid extraction) used for the isolation of aroma-active components from Thymus vulgaris L. are compared in the paper. The methods are mainly discussed with regard to the recovery of components which typically exist in essential oil isolated by steam distillation. According to the obtained data, PLE is the most efficient sample preparation method in determining the essential oil from the thyme herb. Although co-extraction of non-volatile ingredients is the main drawback of this method, it is characterized by the highest yield of essential oil components and the shortest extraction time required. Moreover, the relative peak amounts of essential components revealed by PLE are comparable with those obtained by steam distillation, which is recognized as standard sample preparation method for the analysis of essential oils in aromatic plants.

    Essential oil is the low polar and volatile components distilled or extracted from Ligusticum chuanxiong, the dry root of perennial herb L. chuanxiong, which has proven to be one of the main biological active ingredients of L. chuanxiong. Studies suggested that essential oil of L. chuanxiong mainly contains phthalide, terpene alcohols and fatty acids compounds. Different regions or varied extraction technology had influences on the type and contents of compound in essential oil of L. chuanxiong and the total yield efficiency of essential oil, while the differences among the distribution of compounds leads to the variant pharmacological function of essential oil of L. chuanxiong. Researches confirmed that essential oil of L. chuanxiong has kinds of pharmacological activities such as sedation, analgesia, improve function of blood vessels, protected nerve cells and fever-reducing, all these benefits were verified by experiment studies in vivo and some of which were used as therapies in treating migraine, the underlining mechanisms include anti-inflammation, apoptosis pathway and studies found that essential oil of L. chuanxiong possessed very low acute and chronic toxicity at the same time, revealed its great value of development and utilization in clinical applications. Recent studies light some problems such as lack of quality standards and the research of relationship between efficacy and material. The key to apply the usage of essential oil of L. chuanxiong locate in its substantial basis research, the establishment of the quality standards and the joint research institute, more study should work on these fields.

  8. Essentialism goes social: belief in social determinism as a component of psychological essentialism.

    Rangel, Ulrike; Keller, Johannes

    2011-06-01

    Individuals tend to explain the characteristics of others with reference to an underlying essence, a tendency that has been termed psychological essentialism. Drawing on current conceptualizations of essentialism as a fundamental mode of social thinking, and on prior studies investigating belief in genetic determinism (BGD) as a component of essentialism, we argue that BGD cannot constitute the sole basis of individuals' essentialist reasoning. Accordingly, we propose belief in social determinism (BSD) as a complementary component of essentialism, which relies on the belief that a person's essential character is shaped by social factors (e.g., upbringing, social background). We developed a scale to measure this social component of essentialism. Results of five correlational studies indicate that (a) BGD and BSD are largely independent, (b) BGD and BSD are related to important correlates of essentialist thinking (e.g., dispositionism, perceived group homogeneity), (c) BGD and BSD are associated with indicators of fundamental epistemic and ideological motives, and (d) the endorsement of each lay theory is associated with vital social-cognitive consequences (particularly stereotyping and prejudice). Two experimental studies examined the idea that the relationship between BSD and prejudice is bidirectional in nature. Study 6 reveals that rendering social-deterministic explanations salient results in increased levels of ingroup favoritism in individuals who chronically endorse BSD. Results of Study 7 show that priming of prejudice enhances endorsement of social-deterministic explanations particularly in persons habitually endorsing prejudiced attitudes. 2011 APA, all rights reserved

    The following observations are offered by one who has served on national and international standards-writing committees and standards review committees. Service on working groups consists of either updating previous standards or developing new standards. The process of writing either type of document proceeds along similar lines. The first order of business is to recognise the need for developing or updating a standard and to identify the potential user community. It is also necessary to ensure that there is a required number of members willing to do the writing. A justification is required as to why a new standard should be developed, and this is written as a new work item proposal or a project initiation notification system form. This document must be filed officially and approved, and a search is then undertaken to ensure that the proposed new standard will not duplicate a standard that has already been published or is underway in another standards organisation.

    Milk makes a significant contribution to the human diet through provision of macro nutrient, vitamins and minerals. The exact composition of milk varies by species to naturally or contamination. It is recognized that imbalance quantity of minerals and trace element being a serious health hazards especially for infants. Therefore, some essentials elements like K, Fe, Co and Pb (as a non essential element) have been determined in locally available milk powder of infant formulas, milk powder of growing children , processed milk or tetra pack milk of different brands and fresh milk samples (cow and buffalo) by sophisticated analytical techniques flame emissions spectroscopy (FES) and atomic absorption spectroscopy (AAS). The range of mean concentration of elements (K, Fe and Co) in milk samples was found to be 650.00-1500.00 mg/l, 2.76-8.93 mg/l and 0.05 mg/l respectively. The levels of these elements in milk powder of infant formulas (1 and 2) were compared with the standards of FAO/WHO, recommended values of the Committee on Nutrition of the American Academy of Pediatrics, human milk and cow's milk.

It also provides an approved set of requirements, recommendations, and criteria with which MS may be developed, accepted, and used in support of NASA activities. As the MS disciplines employed and application areas involved are broad, the common aspects of MS across all NASA activities are addressed. The discipline-specific details of a given MS should be obtained from relevant recommended practices. The primary purpose is to reduce the risks associated with MS-influenced decisions by ensuring the complete communication of the credibility of MS results.

In addition to this report on financial management, there are two companion reports on environmental performance entitled E ssential Balance', and on contributions to the community with the title of 'Essential Spirit'. While this report focuses on the Corporation's financial performance, it also provides a summary on the Corporation's growth, operational excellence, regulatory matters, environmental achievements and management of the Corporation's people resources. The financial report includes the customary consolidated financial statements, the auditor's report, and management's discussion and analysis of the financial report. Revenues for 1999 totalled just over one billion dollars ($978 million in 1998); net income was $116 million ($121 million in 1998); operating expenses were higher than in 1998 ($765 million versus $642 million) due to higher natural gas prices; capital spending was $198 million, compared to $153 million in 1998. Operations, maintenance, and administrative costs were also higher in 1999 due to higher employee costs across the EPCOR Group, one-time costs associated with EPCOR's master branding initiative, Y2K testing and remediation, and increased business development costs

    2014-07-01

    Full Text Available In plants grown with artificial lighting, variations in light spectral composition can be used for the directed biosynthesis of the target substances including essential oils, e.g. in plant factories. We studied the effect of light spectral quality on the essential oil composition in Ocimum basilicum and Salvia officinalis plants grown in controlled environment. The variable-spectrum light modules were designed using three types of high-power light-emitting diodes (LEDs with emission peaked in red, blue and red light, white LEDs, and high-pressure sodium lamps as reference. Qualitative and quantitative essential oil determinations were conducted using gas chromatography with mass selective detection and internal standard method.Sweet basil plant leaves contain essential oils (са. 1 % including linalool, pinene, eugenol, camphor, cineole, and other components. And within the genetic diversity of the species, several cultivar groups can be identified according to the flavor (aroma perceived by humans: eugenol, clove, camphor, vanilla basil. Essential oil components produce particular flavor of the basil leaves. In our studies, we are using two sweet basil varieties differing in the essential oil qualitative composition – “Johnsons Dwarf” (camphor as a major component of essential oils and “Johnsons Lemon Flavor” (contains large amount of citral defining its lemon flavor.In sage, essential oil composition is also very variable. As for the plant responses to the light environment, the highest amount of the essential oils was observed at the regimes with white and red + blue LED light. And it was three times less with red light LEDs alone. In the first two environments, thujone accumulation was higher in comparison with camphor, while red LED light and sodium lamp light favored camphor biosynthesis (three times more than thujone. The highest amount of eucalyptol was determined in plants grown with red LEDs.

  19. A forward genetic screen reveals essential and non-essential RNAi factors in Paramecium tetraurelia

    Science.gov (United States)

    Marker, Simone; Carradec, Quentin; Tanty, Véronique; Arnaiz, Olivier; Meyer, Eric

    2014-01-01

    In most eukaryotes, small RNA-mediated gene silencing pathways form complex interacting networks. In the ciliate Paramecium tetraurelia, at least two RNA interference (RNAi) mechanisms coexist, involving distinct but overlapping sets of protein factors and producing different types of short interfering RNAs (siRNAs). One is specifically triggered by high-copy transgenes, and the other by feeding cells with double-stranded RNA (dsRNA)-producing bacteria. In this study, we designed a forward genetic screen for mutants deficient in dsRNA-induced silencing, and a powerful method to identify the relevant mutations by whole-genome sequencing. We present a set of 47 mutant alleles for five genes, revealing two previously unknown RNAi factors: a novel Paramecium-specific protein (Pds1) and a Cid1-like nucleotidyl transferase. Analyses of allelic diversity distinguish non-essential and essential genes and suggest that the screen is saturated for non-essential, single-copy genes. We show that non-essential genes are specifically involved in dsRNA-induced RNAi while essential ones are also involved in transgene-induced RNAi. One of the latter, the RNA-dependent RNA polymerase RDR2, is further shown to be required for all known types of siRNAs, as well as for sexual reproduction. These results open the way for the dissection of the genetic complexity, interconnection, mechanisms and natural functions of RNAi pathways in P. tetraurelia. PMID:24860163

  3. Risk Analysis as Regulatory Science: Toward The Establishment of Standards.

    Science.gov (United States)

    2016-09-01

    Understanding how to establish standards is essential for risk communication and also provides perspectives for further study. In this paper, the concept of risk analysis as regulatory science for the establishment of standards is demonstrated through examples of standards for evacuation and provisional regulation values in foods and drinking water. Moreover, academic needs for further studies related to standards are extracted. The concepts of the traditional 'Standard I', which has a paternalistic orientation, and 'Standard II', established through stakeholder consensus, are then systemized by introducing the current status of the new standards-related movement that developed after the Fukushima nuclear power plant accident, and the perspectives of the standards are discussed. Preparation of standards on the basis of stakeholder consensus through intensive risk dialogue before a potential nuclear power plant accident is suggested to be a promising approach to ensure a safe society and enhance subjective well-being. © The Author 2016.

    There are several issues to be addressed concerning the management and effective use of information (or data), generated from nanotechnology studies in biomedical research and medicine. These data are large in volume, diverse in content, and are beset with gaps and ambiguities in the description and characterization of nanomaterials. In this work, we have reviewed three areas of nanomedicine informatics: information resources; taxonomies, controlled vocabularies, and ontologies; and information standards. Informatics methods and standards in each of these areas are critical for enabling collaboration, data sharing, unambiguous representation and interpretation of data, semantic (meaningful) search and integration of data; and for ensuring data quality, reliability, and reproducibility. In particular, we have considered four types of information standards in this review, which are standard characterization protocols, common terminology standards, minimum information standards, and standard data communication (exchange) formats. Currently, due to gaps and ambiguities in the data, it is also difficult to apply computational methods and machine learning techniques to analyze, interpret and recognize patterns in data that are high dimensional in nature, and also to relate variations in nanomaterial properties to variations in their chemical composition, synthesis, characterization protocols, etc. Progress towards resolving the issues of information management in nanomedicine using informatics methods and standards discussed in this review will be essential to the rapidly growing field of nanomedicine informatics.

    2012-01-01

    Flick standards or magnification standards are widely used for an efficient and functional calibration of the sensitivity of form measuring instruments. The results of a recent measurement comparison have shown to be partially unsatisfactory and revealed problems related to the calibration of these standards. In this paper the influence factors for the calibration of Flick standards using roundness measurement instruments are discussed in detail, in particular the bandwidth of the measurement chain, residual form errors of the device under test, profile distortions due to the diameter of the probing element and questions related to the definition of the measurand. The different contributions are estimated using simulations and are experimentally verified. Also alternative methods to calibrate Flick standards are investigated. Finally the practical limitations of Flick standard calibration are shown and the usability of Flick standards both to calibrate the sensitivity of roundness instruments and to check the filter function of such instruments is analysed.

    2016-12-01

    The significance of the essential trace element zinc for immune function has been known for several decades. Zinc deficiency affects immune cells, resulting in altered host defense, increased risk of inflammation, and even death. The micronutrient zinc is important for maintenance and development of immune cells of both the innate and adaptive immune system. A disrupted zinc homeostasis affects these cells, leading to impaired formation, activation, and maturation of lymphocytes, disturbed intercellular communication via cytokines, and weakened innate host defense via phagocytosis and oxidative burst. This review outlines the connection between zinc and immunity by giving a survey on the major roles of zinc in immune cell function, and their potential consequences in vivo.

    Hearing loss is the most frequent sensory disorder in humans. Auditory hair cells (HCs) are postmitotic at late-embryonic differentiation and postnatal stages, and their damage is the major cause of hearing loss. There is no measurable HC regeneration in the mammalian cochlea, and the maintenance of cell function is crucial for preservation of hearing. Here we generated mice deficient in autophagy-related 5 (Atg5), a gene essential for autophagy, in the HCs to investigate the effect of basal autophagy on hearing acuity. Deletion of Atg5 resulted in HC degeneration and profound congenital hearing loss. In autophagy-deficient HCs, polyubiquitinated proteins and p62/SQSTM1, an autophagy substrate, accumulated as inclusion bodies during the first postnatal week, and these aggregates increased in number. These findings revealed that basal autophagy has an important role in maintenance of HC morphology and hearing acuity.

    To understand why we humans are as we are, it is necessary to look at the essential building blocks that comprise our nature. The foundations of this structure are our evolutionary origins as primates and our social roots. Upon these rest features such as our emotions, language and aesthetic preferences, with our self-perceptions, self-deceptions and thirst for knowledge right at the top. The unifying force holding these blocks together is evolutionary theory. Evolution provides a deeper understanding of human nature and, in particular, of the common roots of these different perspectives. To build a reliable and coherent model of man, leading authors from fields as diverse as primatology, anthropology, neurobiology and philosophy have joined forces to present essays  each describing their own expert perspective. Together they provide a convincing and complete picture of our own human nature.

    Influence of systemic disorders on periodontal diseases is well established. However, of growing interest is the effect of periodontal diseases on numerous systemic diseases or conditions like cardiovascular disease, cerebrovascular disease, diabetes, pre-term low birth weight babies, preeclampsia, respiratory infections and others including osteoporosis, cancer, rheumatoid arthritis, erectile dysfunction, Alzheimer's disease, gastrointestinal disease, prostatitis, renal diseases, which has also been scientifically validated. This side of the oral-systemic link has been termed Periodontal Medicine and is potentially of great public health significance, as periodontal disease is largely preventable and in many instances readily treatable, hence, providing many new opportunities for preventing and improving prognosis of several systemic pathologic conditions. This review article highlights the importance of prevention and treatment of periodontal diseases as an essential part of preventive medicine to circumvent its deleterious effects on general health.

    Full Text Available Abstract Open Access publishing is a valuable resource for the synthesis and distribution of essential health care information. This article discusses the potential benefits of Open Access, specifically in terms of Low and Middle Income (LAMI countries in which there is currently a lack of informed health care providers – mainly a consequence of poor availability to information. We propose that without copyright restrictions, Open Access facilitates distribution of the most relevant research and health care information. Furthermore, we suggest that the technology and infrastructure that has been put in place for Open Access could be used to publish download-able manuals, guides or basic handbooks created by healthcare providers in LAMI countries.

    Curcumin is a constituent (up to ∼5%) of the traditional medicine known as turmeric. Interest in the therapeutic use of turmeric and the relative ease of isolation of curcuminoids has led to their extensive investigation. Curcumin has recently been classified as both a PAINS (pan-assay interference compounds) and an IMPS (invalid metabolic panaceas) candidate. The likely false activity of curcumin in vitro and in vivo has resulted in >120 clinical trials of curcuminoids against several diseases. No double-blinded, placebo controlled clinical trial of curcumin has been successful. This manuscript reviews the essential medicinal chemistry of curcumin and provides evidence that curcumin is an unstable, reactive, nonbioavailable compound and, therefore, a highly improbable lead. On the basis of this in-depth evaluation, potential new directions for research on curcuminoids are discussed.

    Full Text Available Essential thrombocythemia (ET is a clonal myeloproliferative disorder (MPD, characterized predominantly by a markedly elevated platelet count without known cause. It is rare hematological disorder. In ET clinical picture is dominated by a predisposition to vascular occlusive events and hemorrhages. Headache, transient ischemic attack, stroke, visual disturbances and light headedness are some of the neurological manifestations of ET. Here, we describe a 55 year-old female who presented to us with generalized chorea. On evaluation, she was found to have thrombocytosis. After ruling out the secondary causes of thrombocytosis and other MPD we confirmed diagnosis of ET in her by bone marrow studies. Polycythemia vera (PV another MPD closely related to ET may be present with generalized chorea. There are few case reports of PV presenting as chorea in the literature, but none with ET. We report the first case of ET presenting as generalized chorea.

  19. The dioxins - essential characteristics. Pt. 1

    Polychlorinated dibenzo-p-dioxins (PCDD) belong to the group of persistent chlorinated hydrocarbons. They are predominantly of anthropogenic origin, except for those originating from fires caused by lightning or volcanic eruption. PCDD, according to the present knowledge, are absolutely useless. They are toxic, lipophilic, hardly degradable, and therefore ubiquitous in environment and food chain. PCDD have also been found in breast milk. Because their carcinogenic mechanism of action is little known, the toxicological evaluation of PCDD is still incomplete. Even lowest concentrations of PCDD may be detrimental to health. These characteristics are reason with enough to group PCDD not with xenobiotics, but with harmful substances. Closely related to PCDD in their origin and characteristics are polychlorinated dibenzofuranes (PCDF), which therefore are frequently ranked among ''the dioxins'': Essential characteristics of PCDD and PCDF are discussed.

    2008-10-01

    Full Text Available This paper explores how language and culture are intertwined and often regarded as “invariable fixed properties” in contemporary South Africa by focusing on one particular indigenous African language group, i.e. isiZulu-speakers. Drawing from general theoretical sociolinguistic approaches to language and culture and considering South Africa’s socio-political history, the paper demonstrates the significance and saliency of Zulu linguistic culture to Zulu people in the post-apartheid state. It is examined, how Zulu linguistic culture is regarded a resource in the isiZulu-speaking community and as one of the most salient tools of in-group identification in the larger contemporary South African society. Zulu people’s culture is profoundly language-embedded and Zulu linguistic culture often based on essentialism.

  1. Yeasts are essential for cocoa bean fermentation.

    Cocoa beans (Theobroma cacao) are the major raw material for chocolate production and fermentation of the beans is essential for the development of chocolate flavor precursors. In this study, a novel approach was used to determine the role of yeasts in cocoa fermentation and their contribution to chocolate quality. Cocoa bean fermentations were conducted with the addition of 200ppm Natamycin to inhibit the growth of yeasts, and the resultant microbial ecology and metabolism, bean chemistry and chocolate quality were compared with those of normal (control) fermentations. The yeasts Hanseniaspora guilliermondii, Pichia kudriavzevii and Kluyveromyces marxianus, the lactic acid bacteria Lactobacillus plantarum and Lactobacillus fermentum and the acetic acid bacteria Acetobacter pasteurianus and Gluconobacter frateurii were the major species found in the control fermentation. In fermentations with the presence of Natamycin, the same bacterial species grew but yeast growth was inhibited. Physical and chemical analyses showed that beans fermented without yeasts had increased shell content, lower production of ethanol, higher alcohols and esters throughout fermentation and lesser presence of pyrazines in the roasted product. Quality tests revealed that beans fermented without yeasts were purplish-violet in color and not fully brown, and chocolate prepared from these beans tasted more acid and lacked characteristic chocolate flavor. Beans fermented with yeast growth were fully brown in color and gave chocolate with typical characters which were clearly preferred by sensory panels. Our findings demonstrate that yeast growth and activity were essential for cocoa bean fermentation and the development of chocolate characteristics. Crown Copyright © 2014. Published by Elsevier B.V.

    2007-03-01

    The muon anomalous magnetic moment is one of the most precisely measured quantities in particle physics. Recent high precision measurements (0.54 ppm) at Brookhaven reveal a ''discrepancy'' by 3 standard deviations from the electroweak Standard Model which could be a hint for an unknown contribution from physics beyond the Standard Model. This triggered numerous speculations about the possible origin of the ''missing piece''. The remarkable 14-fold improvement of the previous CERN experiment, actually animated a multitude of new theoretical efforts which lead to a substantial improvement of the prediction of a μ . The dominating uncertainty of the prediction, caused by strong interaction effects, could be reduced substantially, due to new hadronic cross section measurements in electron-positron annihilation at low energies. After an introduction and a brief description of the principle of the experiment, I present a major update and review the status of the theoretical prediction and discuss the role of the hadronic vacuum polarization effects and the hadronic light-by-light scattering contribution. Prospects for the future are briefly discussed. As, in electroweak precision physics, the muon g-2 shows the largest established deviation between theory and experiment at present, it will remain one of the hot topics for further investigations.

    Kahramanmaras, is a developing city located in the southern part of Turkey Thymus eigii (M. Zohary and RH. Davis) Jalas, Pinus nigraAm. sub sp pallasiana and Cupressus sempervirens L. are the useful plants of the Kahramanmaras province and have been understudy since 2004 for the traditional uses of plants empiric drug, spice, herbal tea industry herbal gum and fuel. The study was designed to examine the antimicrobial activities of essential oils of these plants by the disc diffusion and minimum inhibitory concentration (MIC) methods. In addition, antimicrobial activity of Thymus eigii was researched by effects when it was used together with antibiotics and even when it was combined with other essential oils. When the results of this study were compared with vancomycin (30 mcg) and erytromycin (15 mcg) standards, it was found that Thymus eigii essential oil was particularly found to possess strongerantimicrobial activity whereas other essential oils showed susceptible or moderate activity However, antimicrobial activity changed also by in vitro interactions between antibiotics and Thymus eigii essential oil, also between essential oils of these plants and that of Thymus eigii causing synergic, additive, antagonist effect.

    This study has been considered effect of Ferulago angulata essential oil on stabilizing soybean oil during accelerated storage. The essential oil was extracted by Clevenger-type apparatus. For analysis of the essential oil, GC/MS was used. Main components of the essential oil were monoterpene and sesquiterpene hydrocarbons. The essential oil of F. angulata at four concentrations, i.e. 125 (SBO-125), 250 (SBO-250), 500 (SBO-500) and SBO-Mixture (60 ppm TBHQ +60 ppm essential oil) were added to preheated refined soybean oil. TBHQ was used at 120 ppm as standard besides the control. Antioxidant activity index (AAI), free fatty acid (FFA) content, peroxide value (PV) and p-anisidine value (p-AnV) were served for appreciation of efficacy of F. angulata in stabilization of soybean oil. Results from different tests showed that SBO-mixture had highest effect and followed by SBO-TBHQ, SBO-250, SBO-125, SBO-500 and Ctrl. These results reveal F. angulata is a strong antioxidant and can be used instead of synthetic antioxidant.

    The chemical composition, including the enantiomeric excess of the main terpenes, of essential oils from seeds and cones of Abies concolor was studied by chromatographic (GC) and spectroscopic methods (mass spectrometry, nuclear magnetic resonance), leading to the determination of 98 compounds. Essential oils were mainly composed of monoterpene hydrocarbons. The dominant volatiles of seed essential oil were: limonene (47 g/100 g, almost pure levorotary form) and α-pinene (40 g/100 g), while α-pinene (58 g/100 g), sabinene (11 g/100 g), and β-pinene (4.5 g/100 g) were the predominant components of the cone oil. The seed and cone essential oils exhibited mild antibacterial activity, and the MIC ranged from 26 to 30 μL/mL against all of the tested bacterial standard strains: Staphylococcus aureus , Enterococcus faecalis , Enterococcus faecium , Escherichia coli , and Klebsiella pneumoniae . The cytotoxic studies have demonstrated that tested essential oils were cytotoxic to human skin fibroblasts and human microvascular endothelial cells at concentrations much lower than the MIC. The essential oils from A. concolor seeds and cones had no toxic effect on human skin fibroblasts and human microvascular endothelial cells, when added to the cells at a low concentration (0-0.075 μL/mL) and (0-1.0 μL/mL), respectively, and cultured for 24 h.

It will be an honour and a pleasure to work together with all these talented people towards the high-minded goal of running a world-class scientific journal. As Editor-in-Chief of J. Phys. A, my principal objective will be to raise the standards of this first-rate journal to even higher levels by raising the quality of accepted papers. I believe that this goal will be possible to accomplish. Despite an already high rejection rate, paper submissions are rising rapidly and I anticipate that we will need to be even more stringent in our assessment of quality next year. A letter has already been sent to referees urging them to raise their standards for acceptance. I believe we will make rapid progress in this direction. (I have heard a few people criticize the journal for being a `write-only' journal. My goal is for the worldwide community of mathematical physicists to view J. Phys. A as essential reading.) I am extremely optimistic about the future of J. Phys. A. I believe that we will raise the standards of acceptance while maintaining the short time from submission to decision. I am confident that we will continue to improve the quality of the papers published in this already first-class journal. I look forward to working with the journal's excellent staff, the Board of Editors, and the Advisory Panel.

    The lecture traces the development of nuclear standards, codes, and Federal regulations on quality assurance (QA) for nuclear power plants and associated facilities. The technical evolution of the last twelve years, especially in the area of nuclear technology, led to different activities and regulatory initiatives, and the present result is: several nations have their own homemade standards. The lecture discusses the former and especially current activities in standard development, and gives a description of the requirements of QA-standards used in USA and Europe, especially Western Germany. Furthermore the lecture attempts to give a comparison and an evaluation of the international quality standards from the author's viewpoint. Finally the lecture presents an outlook for the future international implications of QA-standards. There is an urgent need within the nuclear industry for simplification and standardization of QA-standards. The relationship between the various standards, and the applicability of the standards need clarification and a better transparancy. To point out these problems is the purpose of the lecture. (orig.)

    2013-08-01

    Many scientific models of emotion assume that emotion categories are natural kinds that carve nature at its joints. These beliefs remain strong, despite the fact that the empirical record on the issue has remained equivocal for over a century. In this research, the authors examined one reason for this situation: People essentialize emotion categories by assuming that members of the same category (e.g., fear) have a shared metaphysical essence (i.e., a common causal mechanism). In Study 1, the authors found that lay people essentialize emotions by assuming that instances of the same emotion category have a shared essence that defines them, even when their surface features differ. Study 2 extended these findings, demonstrating that lay people tend to essentialize categories the more a category is of the body (vs. the mind). In Study 3, we examined the links between emotion essentialism and the complexity of actual emotional experiences. In particular, we predicted and found that individuals who hold essentialist beliefs about emotions describe themselves as experiencing highly differentiated emotional experiences but do not show evidence of stronger emotional differentiation in their momentary ratings of experience in everyday life. Implications for the science of emotion are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    A number of elements/metals have increased in arctic biota and are of concern due to their potential toxicity. Most studies on elements in the Arctic have focused on marine mammals and seabirds, but concentrations in the Greenland shark (Somniosus microcephalus) and Pacific sleeper shark (Somniosus pacificus), the only two shark species known to regularly inhabit arctic waters, have never been reported. To address this data gap, concentrations and patterns of 25 elements were analyzed in liver of Greenland sharks collected about Cumberland Sound (n = 24) and Pacific sleeper sharks collected about Prince William Sound (n = 14). Several non-essential elements differed between species/locations, which could suggest geographical exposure differences or ecological (e.g., diet) differences between the species. Certain essential elements also differed between the two sleeper sharks, which may indicate different physiological requirements between these closely related shark species, although information on such relationships are lacking for sharks and fish. - Patterns of essential and non-essential elements provide insight into sleeper shark biology and physiology.

    This paper arranges the essential facility doctrine in America and describes it according to each judgment example how the doctrine is applied on the access of electricity supply companies to transmission grids. By applying the result to the situation of Japan, the point at issue occurring in the range of the Anti-Monopoly Law was arranged and investigated when third parties (power generating manufacturers) access the transmission grids of electricity supply companies in the form of wholesale or self transmission in the electricity supply industry of Japan. In the judgment example of America, a transmission grid can be considered as essential facility. The refusal of essential facility application is judged to be illegal only when it aims at keeping and expanding the leading market share without a fair reason. The application of essential facility can be refused when the transmission line is insufficient in capacity, when no necessary technical conditions are satisfied during use, or when the cost generated during use cannot be collected. 18 refs., 7 figs., 2 tabs.

  14. ASTM reference radiologic digital image standards

    Wysnewski, R.; Wysnewski, D.

    1996-01-01

    ASTM Reference Radiographs have been essential in defining industry's material defect grade levels for many years. ASTM Reference Radiographs are used extensively as even the American Society for Metals Nondestructive Inspection and Quality Control Metals Handbook, Volume 11, eighth edition refers to ASTM Standard Reference Radiographs. The recently published E 1648 Standard Reference Radiographs for Examination of Aluminum Fusion Welds is a prime example of the on-going need for these references. To date, 14 Standard Reference Radiographs have been published to characterize material defects. Standard Reference Radiographs do not adequately address film-less radiologic methods. There are differences in mediums to content with. On a computer CRT defect indications appear differently when compared to indications viewed in a radiograph on a view box. Industry that uses non-film radiologic methods of inspection can be burdened with additional time and money developing internal standard reference radiologic images. These references may be deemed necessary for grading levels of product defects. Because there are no ASTM Standard Reference Radiologic data files for addressing this need in the industry, the authors of this paper suggested implementing a method for their creation under ASTM supervision. ASTM can assure continuity to those users making the transition from analog radiographic images to digital image data by swiftly addressing the requirements for reference digital image standards. The current status and possible future activities regarding a method to create digital data files is presented in this paper summary

    Full Text Available Health; as a basic right of the people and essential demand; should be considered as a joint responsibility of the government and people of a community. As much as the people of a community aware and involved in the individual health promotion and problem solving of their community in all dimensions, the probability of reaching to favorable health measurements is also increased. Community assessment is considered as a foundation for health improving and promoting the community members. The main objectives of community assessment are; to identify factors that affect the health of a population and determine the availability of resources within the community to adequately address these factors. In this Vera, community leaders, public health agencies, businesses, hospitals, private practitioners, and academic centers have each one a defined role. These groups can begin to answer key questions such as (a “What are the strengths in our community?” (b “What health concerns do community members have?” and (c “What resources are available and what do we need in the community to address these concerns? An important use of a community health assessment is to create Community Health Action to develop effective community health strategies. The health reform plan of Islamic Republic of Iran, started at the earlier months of the current year (2014, with establishing of the family physician program begun firstly at the level of rural regions, then will developed to cities with population 20000 to 500000 also borderlines of metropolitans cities and finally in the future, covering all urban eras of cities in the country aimed to executive the referral system with all its attributes. Being a full time physician along with a comprehensive teamwork including different prestigious health workers prepare a gold opportunity for implementation of community assessment in these regions. Although, some efforts have been accomplished in some parts of country by

    Biodiversity data derive from myriad sources stored in various formats on many distinct hardware and software platforms. An essential step towards understanding global patterns of biodiversity is to provide a standardized view of these heterogeneous data sources to improve interoperability. Fundamental to this advance are definitions of common terms. This paper describes the evolution and development of Darwin Core, a data standard for publishing and integrating biodiversity information. We focus on the categories of terms that define the standard, differences between simple and relational Darwin Core, how the standard has been implemented, and the community processes that are essential for maintenance and growth of the standard. We present case-study extensions of the Darwin Core into new research communities, including metagenomics and genetic resources. We close by showing how Darwin Core records are integrated to create new knowledge products documenting species distributions and changes due to environmental perturbations. PMID:22238640

    NIM is a standard modular instrumentation system that is in wide use throughout the world. As the NIM system developed and accommodations were made to a dynamic instrumentation field and a rapidly advancing technology, additions, revisions and clarifications were made. These were incorporated into the standard in the form of addenda and errata. This standard is a revision of the NIM document, AEC Report TID-20893 (Rev. 4) dated July 1974. It includes all the addenda and errata items that were previously issued as well as numerous additional items to make the standard current with modern technology and manufacturing practice

    An objective and scientific task analysis provides the basis for establishing legally defensible Physical Employment Standards (PES), based on common and essential occupational tasks. Infrequent performance of these tasks creates challenges when developing PES based on criterion, or content validity. Develop a systematic approach using Subject Matter Experts (SME) to provide tasks with 1) an occupationally relevant scenario considered common to all personnel; 2) a minimum performance standard defined by time, distance, load or work. Examples provided here relate to the development of a new PES for the Canadian Armed Forces (CAF). SME of various experience are selected based on their eligibility criteria. SME are required to define a reasonable scenario for each task from personal experience, provide occupational performance requirements of the scenario in sub-groups, and discuss and agree by consensus vote on the final standard based on the definition of essential. A common and essential task for the CAF is detailed as a case example of process application. Techniques to avoid common SME rating errors are discussed and advantages to the method described. The SETS method was developed as a systematic approach to setting occupational performance standards and qualifying information from SME.

    As The World health report 2006 emphasized, there is increasing consensus that training programmes should focus on "know-how" instead of "know-all." Health workers need to know how to do the job they will be expected to do. IntraHealth International's Learning for performance: a guide and toolkit for health worker training and education programs offers a step-by-step, customizable approach designed to develop the right skills linked to job responsibilities. Using Learning for performance (LFP) yields more efficient training that focuses on what is essential for health workers to do their jobs and on effective learning methods, while addressing the factors that ensure application of new skills on the job. This brief communication describes the Learning for performance approach and initial findings from its application for pre-service education and in-service training in three countries: India, Mali and Bangladesh. Based on IntraHealth's experiences, the author provides thoughts on how LFP's performance-based learning approach can be a useful tool in training scale-up to strengthen human resources for health.

    Argentieri, Maria Pia; De Lucia, Barbara; Cristiano, Giuseppe; Avatoa Pinarosa

    2016-03-01

    The genus Lavandula includes about thirty species plus a number of intraspecific taxa and hybrids, which are distributed in the Mediterranean area. The traditional use of lavender both as perfume or medicinal plant is known since antiquity. Nowadays several species are extensively cultivated for the extraction of their essential oils (EOs) which are used in manufactured products like cosmetics and perfumes or in phytotherapy. Lavandula pinnata L. f. (syn L. pinnata Lundmark) is a rare species native to the Canary Islands used in folk medicine as relaxant and also a valuable remedy against bites. To the best of our knowledge, EOs from L. pinnata have been very little studied. The present paper reports on the quali- and quantitative compositional profile of the EOs distilled (by a Spring type apparatus) from the aerial parts (flowers and leaves) of this species cultivated in soilless conditions. Chemical analyses by means of GC and GC-MS techniques have indicated that oxygenated monoterpenes are the main constituents of both the flowers (68.30%) and the leaves (83.65%). Carvacrol is the main compound which characterizes the EOs of this species. In addition, discrete amounts of spathulenol (12.22%) and caryophyllene oxide (14.62%) have been detected in flowers EOs, while leaves EOs contained small amounts of carvacrol methyl ether (2.52%).

    A significant number of patients with essential thrombocythemia (ET) complain of symptoms including distal parts of the extremities (e.g., paresthesias or Raynaud's phenomenon). The aim of the present study was to examine peripheral circulation in the upper extremities of individuals with ET. The study included 45 ET patients and 30 control subjects. All participants were subjected to thermography, photoplethysmography, impedance plethysmography, and applanation tonometry pulse wave analysis. The patients with ET differed significantly from the control subjects in terms of 3rd finger skin temperature (mean 31.04 vs. 32.45°C), skin temperature gradient (mean 1.82 vs. 0.11°C), photoplethysmographic amplitude (median 0.25 vs. 0.74%), and pulse waveform in the radial artery (more frequent occurrence of type B waveform). Pulse wave parameters correlated with the skin temperature gradient. The study findings imply the altered regulation of peripheral circulation in ET, including a decreased flow and an increased resistance. Copyright © 2017 Elsevier Inc. All rights reserved.

    Video games are more popular than ever and the general public, including parents, educators, and the media, tends to consider intense video gaming fundamentally problematic. To test this hypothesis, participants were recruited via gaming-related websites resulting in a sample of N = 5,222 online video gamers (mean age: 22.2 years, SD = 6.4). Besides assessing gaming time, we administered the Ten-Item Internet Gaming Disorder Test, the Brief Symptom Inventory, and the Motives for Online Gaming Questionnaire. Two structural regression models were estimated with both gaming time and problematic gaming as outcome variables. Predictors were psychiatric symptoms in the first, and gaming motives in the second model. Both models yielded adequate fit indices. Psychiatric symptoms had a moderate positive effect on problematic use (β = .46, p gaming time was practically zero (β = -.01, p = .84). In the second model, Escape was the most prominent motive and was moderately to-strongly associated (β = .58, p gaming time was substantially weaker (β = .21, p gaming time and problematic use was weak-to-moderate in both models (r = .26, p gaming time is weakly associated with negative psychological factors such as psychiatric symptoms and Escape motive, which were found to be consistently related to problematic use. Therefore, the amount of gaming time alone appears to be an unreliable predictor of problematic use, which questions the aforementioned idea that intense gaming is essentially problematic.

  10. Is seed conditioning essential for Orobanche germination?

    Science.gov (United States)

    Plakhine, Dina; Ziadna, Hammam; Joel, Daniel M

    2009-05-01

    Parasitic Orobanchaceae germinate only after receiving a chemical stimulus from roots of potential host plants. A preparatory phase of several days that follows seed imbibition, termed conditioning, is known to be required; thereafter the seeds can respond to germination stimulants. The aim of this study was to examine whether conditioning is essential for stimulant receptivity. Non-conditioned seeds of both Orobanche cumana Wallr. and O. aegyptiaca Pers. [syn. Phelipanche aegyptiaca (Pers.) Pomel] were able to germinate in response to chemical stimulation by GR24 even without prior conditioning. Stimulated seeds reached maximal germination rates about 2 weeks after the onset of imbibition, no matter whether the seeds had or had not been conditioned before stimulation. Whereas the lag time between stimulation and germination response of non-conditioned seeds was longer than for conditioned seeds, the total time between imbibition and germination was shorter for the non-conditioned seeds. Unlike the above two species, O. crenata Forsk. was found to require conditioning prior to stimulation. Seeds of O. cumana and O. aegyptiaca are already receptive before conditioning. Thus, conditioning is not involved in stimulant receptivity. A hypothesis is put forward, suggesting that conditioning includes (a) a parasite-specific early phase that allows the imbibed seeds to overcome the stress caused by failing to receive an immediate germination stimulus, and (b) a non-specific later phase that is identical to the pregermination phase between seed imbibition and actual germination that is typical for all higher plants.

  11. Social class rank, essentialism, and punitive judgment.

    Science.gov (United States)

    Kraus, Michael W; Keltner, Dacher

    2013-08-01

    Recent evidence suggests that perceptions of social class rank influence a variety of social cognitive tendencies, from patterns of causal attribution to moral judgment. In the present studies we tested the hypotheses that upper-class rank individuals would be more likely to endorse essentialist lay theories of social class categories (i.e., that social class is founded in genetically based, biological differences) than would lower-class rank individuals and that these beliefs would decrease support for restorative justice--which seeks to rehabilitate offenders, rather than punish unlawful action. Across studies, higher social class rank was associated with increased essentialism of social class categories (Studies 1, 2, and 4) and decreased support for restorative justice (Study 4). Moreover, manipulated essentialist beliefs decreased preferences for restorative justice (Study 3), and the association between social class rank and class-based essentialist theories was explained by the tendency to endorse beliefs in a just world (Study 2). Implications for how class-based essentialist beliefs potentially constrain social opportunity and mobility are discussed.

    Full Text Available Allspice essential oil was extracted with supercritical carbon dioxide (SC-CO2 in a static process at three different temperatures (308.15, 313.15, and 318.15 K and four levels of pressure (100, 200, 300, and 360 bar. The amount of oil extracted was measured at intervals of 1, 2, 3, 4, 5, and 6 h; the most extraction yield reached was of 68.47% at 318.15 K, 360 bar, and 6 h of contact time. In this supercritical extraction process, the distribution coefficient (KD, the mean effective diffusion coefficient (Def, the energy of activation (Ea, the thermodynamic properties (ΔG0, ΔH0, and ΔS0, and the apparent solubility (S expressed as mass fraction (w/w were evaluated for the first time. At the equilibrium the experimental apparent solubility data were successfully correlated with the modified Chrastil equation.

    Bergamot (Citrus bergamia, Risso) is a fruit most knowledgeable for its essential oil (BEO) used in aromatherapy to minimize symptoms of stress-induced anxiety and mild mood disorders and cancer pain though the rational basis for such applications awaits to be discovered. The behavioural and EEG spectrum power effects of BEO correlate well with its exocytotic and carrier-mediated release of discrete amino acids endowed with neurotransmitter function in the mammalian hippocampus supporting the deduction that BEO is able to interfere with normal and pathological synaptic plasticity. The observed neuroprotection in the course of experimental brain ischemia and pain does support this view. In conclusion, the data yielded so far contribute to our understanding of the mode of action of this phytocomplex on nerve tissue under normal and pathological experimental conditions and provide a rational basis for the practical use of BEO in complementary medicine. The opening of a wide venue for future research and translation into clinical settings is also envisaged. Copyright (c) 2010 Elsevier B.V. All rights reserved.

  14. Probable essential thrombocythemia in a dog

    Hopper, P.E.; Mandell, C.P.; Turrel, J.M.; Jain, N.C.; Tablin, F.; Zinkl, J.G.

    1989-04-01

    Essential thrombocythemia (ET), in an 11-year-old dog was characterized by persistently high platelet counts range, 4.19 X 10(6)/microliters to 4.95 X 10(6)/microliters, abnormal platelet morphology, marked megakaryocytic hyperplasia in the bone marrow, absence of circulating megakaryoblasts, and history of splenomegaly and gastrointestinal bleeding. Increased numbers of megakaryocytes and megakaryoblasts (15% to 20%) in the bone marrow were confirmed by a positive acetylcholinesterase reaction. Another significant finding was the presence of a basophilia in blood (4,836/microliters) and bone marrow. The marked persistent thrombocytosis, absence of reactive (secondary) thrombocytosis, abnormal platelet morphology, and quantitative and qualitative changes in the megakaryocytic series in the bone marrow suggested the presence of a myeloproliferative disease. Cytochemical and ultrastructural findings aided in the diagnosis of ET. The dog was treated with radiophosphorus. The results was a rapid decline in the numbers of megakaryoblasts and megakaryocytes in the bone marrow and platelets and basophils in the peripheral blood. The dog died unexpectedly of acute necrotizing pancreatitis and diabetes mellitus before a complete remission was achieved.

  15. Carbon Monoxide: An Essential Signalling Molecule

    Science.gov (United States)

    Mann, Brian E.

    Carbon monoxide (CO), like nitric oxide (NO), is an essential signalling molecule in humans. It is active in the cardiovascular system as a vasodilator. In addition, CO possesses anti-inflammatory, anti-apoptotic and anti-proliferative properties and protects tissues from hypoxia and reperfusion injury. Some of its applications in animal models include suppression of organ graft rejection and safeguarding the heart during reperfusion after cardiopulmonary bypass surgery. CO also suppresses arteriosclerotic lesions following angioplasty, reverses established pulmonary hypertension and mitigates the development of post-operative ileus in the murine small intestine and the development of cerebral malaria in mice as well as graft-induced intimal hyperplasia in pigs. There have been several clinical trials using air-CO mixtures for the treatment of lung-, heart-, kidney- and abdominal-related diseases. This review examines the research involving the development of classes of compounds (with particular emphasis on metal carbonyls) that release CO, which could be used in clinically relevant conditions. The review is drawn not only from published papers in the chemical literature but also from the extensive biological literature and patents on CO-releasing molecules (CO-RMs).

  5. Position paper on standardization

    International Nuclear Information System (INIS)

    1991-04-01

    The ''NPOC Strategic Plan for Building New Nuclear Plants'' creates a framework within which new standardized nuclear plants may be built. The Strategic Plan is an expression of the nuclear energy industry's serious intent to create the necessary conditions for new plant construction and operation. One of the key elements of the Strategic Plan is a comprehensive industry commitment to standardization: through design certification, combined license, first-of-a-kind engineering, construction, operation and maintenance of nuclear power plants. The NPOC plan proposes four stages of standardization in advanced light water reactors (ALWRs). The first stage is established by the ALWR Utility Requirements Document which specifies owner/operator requirements at a functional level covering all elements of plant design and construction, and many aspects of operations and maintenance. The second stage of standardization is that achieved in the NRC design certification. This certification level includes requirements, design criteria and bases, functional descriptions and performance requirements for systems to assure plant safety. The third stage of standardization, commercial standardization, carries the design to a level of completion beyond that required for design certification to enable the industry to achieve potential increases in efficiency and economy. The final stage of standardization is enhanced standardization beyond design. A standardized approach is being developed in construction practices, operating, maintenance training, and procurement practices. This comprehensive standardization program enables the NRC to proceed with design certification with the confidence that standardization beyond the regulations will be achieved. This confidence should answer the question of design detail required for design certification, and demonstrate that the NRC should require no further regulatory review beyond that required by 10 CFR Part 52

    The aim of this work was to characterize the ability of essential oils to support antibiotics against pathogenic bacteria in wounds. Gram-positive and Gram-negative bacteria obtained from wound infections were identified according to standard microbiological methods. Essential oils were analysed by GC-FID-MS. The susceptibility of bacteria to antibiotics, essential oils and their combination was assessed using the disc-diffusion method. The Minimal Inhibitory Concentration and Minimum Bactericidal Concentration of the essential oils were established by the micro-dilution broth method. Although cinnamon, clove, thyme and lavender essential oils were found to have the greatest antibacterial activity when used alone, the greatest additive and synergistic effects against pathogenic wound bacteria in combination with recommended antibiotics were demonstrated by basil, clary sage and rosemary oils.

    It has been recently recognized that oxidative stress, helminth and microbial infections are the cause of much illness found in the underdeveloped, developing and developed countries. The present study was undertaken to identify the chemical composition, and to assess anthelmintic, antimicrobial and antioxidant effects of Thymus bovei essential oil. The chemical composition of the essential oil was analyzed using gas chromatography mass spectrometry (GC-MS). Antimicrobial activity was tested against the selected strains from American Type Culture Collection (ATCC) and clinical isolates such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Methicillin Resistant Staphylococcus aureus, Candida albicans using MIC assay. The anthelmintic assay was carried out on adult earthworm (Pheretima posthuma), while antioxidant activity was analyzed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. Trans-geraniol (35.38 %), α-citral (20.37 %) and β-citral (14.76 %) were the major compounds comprising 70.51 % of the essential oil. Our results showed that T. bovei essential oil exhibited strong anthelmintic activity, even higher than piperazine citrate, the used reference standard, with potential antioxidant activity almost equal to the Trolox standard. Furthermore, T. bovei essential oil had powerful antibacterial and antifungal activities against the studied pathogens. Essential oil of T. bovei exerted excellent antioxidant, antimicrobial, and anthelmintic activities. Moreover, this study found that T. bovei volatile oil contains active substances that could potentially be used as natural preservatives in food and pharmaceutical industries, these substances could also be employed for developing new anthelmintic, antimicrobial and antioxidant agents.

    Birčiaková Naďa

    2015-09-01

    Full Text Available This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

    The current research offers an alternative to essentialism for studying cultural variation in emotional experience. Rather than assuming that individuals always experience an emotion in the same way, our starting point was that the experience of an emotion like anger or shame may vary from one instance to another. We expected to find different anger and shame experience types, that is, groups of people who differ in the instances of anger and shame that they experience. We proposed that studying cultural differences in emotional experience means studying differences in the distribution of these types across cultural contexts: There should be systematic differences in the types that are most common in each culture. Students from the United States, Japan, and Belgium (N = 928) indicated their emotional experiences in terms of appraisals and action tendencies in response to 15 hypothetical anger or shame situations. Using an inductive clustering approach, we identified anger and shame types who were characterized by different patterns of anger and shame experience. As expected, we found that the distribution of these types differed across the three cultural contexts: Of the two anger types, one was common in Japan and one in the United States and Belgium; the three shame types were each most prevalent in a different cultural context. Participants' anger and shame types were primarily predicted by their culture of origin (with an accuracy of 72.3% for anger and 74.0% for shame) and not, or much less, by their ethnic origin, socioeconomic status, gender, self-construal, or personality.

    According to Sendai Framework for Disaster Risk Reduction 2015 - 2030 Leaf Area Index (LAI) is considered as one of essential climatic variables. This variable represents the amount of leaf material in ecosystems and controls the links between biosphere and atmosphere through various processes and enables monitoring and quantitative assessment of vegetation state. LAI has added value for such important global resources monitoring tasks as drought mapping and crop yield forecasting with use of data from different sources [1-2]. Remote sensing data from space can be used to estimate such biophysical parameter at regional and national scale. High temporal satellite imagery is usually required to capture main parameters of crop growth [3]. Sentinel-2 mission launched in 2015 be ESA is a source of high spatial and temporal resolution satellite imagery for mapping biophysical parameters. Products created with use of automated Sen2-Agri system deployed during Sen2-Agri country level demonstration project for Ukraine will be compared with our independent results of biophysical parameters mapping.

  11. Essential parameters in eddy current inspection

    Stepinski, T.

    2000-05-01

    Our aim was to qualitatively analyze a number of variables that may affect the result of eddy current (EC) inspection but because of various reasons are not considered as essential in common practice. In the report we concentrate on such variables that can vary during or between inspections but their influence is not determined during routine calibrations. We present a qualitative analysis of the influence of the above-mentioned variables on the ability to detect and size flaws using mechanized eddy current testing (ET). ET employs some type of coil or probe, sensing magnetic flux generated by eddy currents induced in the tested specimen. An amplitude-phase modulated signal (with test frequency f0 ) from the probe is sensed by the EC instrument. The amplitude-phase modulated signal is amplified and demodulated in phase-sensitive detectors removing carrier frequency f0 from the signal. The detectors produce an in-phase and a quadrature component of the signal defining it as a point in the impedance plane. Modern instruments are provided with a screen presenting the demodulated and filtered signal in complex plane. We focus on such issues, related to the EC equipment as, probe matching, distortion introduced by phase discriminators and signal filters, and the influence of probe resolution and lift-off on sizing. The influence of different variables is investigated by means of physical reasoning employing theoretical models and demonstrated using simulated and real EC signals. In conclusion, we discuss the way in which the investigated variables may affect the result of ET. We also present a number of practical recommendations for the users of ET and indicate the areas that are to be further analyzed

    Full Text Available Background: The study on transcranial sonocraphy (TCS as a diagnostic test for Parkinson′s disease (PD has been neglected in some hospitals. The current study was conducted as the first study to investigate the utility of TCS for diagnosis of PD and its ability to distinguish PD from essential tremor (ET in an Iranian population. Materials and Methods: TCS of substantia nigra (SN was performed on 50 PD, 48 ET, and 50 healthy controls by two blinded investigators. Results: Bilateral SN margin over 0.20 cm 2 was found in 39 (90% and 7 (15% in PD and ET patients, respectively. Furthermore, 4 (8% of healthy control displayed this particular echo feature as well (false positives. SN hyperechogenicity ≥0.20 cm 2 was considered as a cut-off point to detected PD. Accordingly, TCS proved 90% (95% confidence interval [CI]: 77.85-97.35 sensitive and 92% ( 95% CI: 80.75-97.73 specific for the detection of PD by visualizing the SN. Conclusion: SN hyperechogenicity ≥20 cm 2 is a specific feature of PD. Since, the symptoms of PD and ET might be overlapping; this method seems to be reliable to confirm PD diagnosis in doubtful clinical cases. Further studies in years to come are warranted to shed light on standardized data for Iranian to enhance the validity of TCS.

  13. Thorium and Molten Salt Reactors: Essential Questions for Classroom Discussions

    2018-04-01

    A little-known type of nuclear reactor called the "molten salt reactor" (MSR), in which nuclear fuel is dissolved in a liquid carrier salt, was proposed in the 1940s and developed at the Oak Ridge National Laboratory in the 1960s. Recently, the MSR has generated renewed interest as a remedy for the drawbacks associated with conventional uranium-fueled light-water reactors (LWRs) in use today. Particular attention has been given to the "thorium molten salt reactor" (TMSR), an MSR engineered specifically to use thorium as its fuel. The purpose of this article is to encourage the TPT community to incorporate discussions of MSRs and the thorium fuel cycle into courses such as "Physics and Society" or "Frontiers of Physics." With this in mind, we piloted a pedagogical approach with 27 teachers in which we described the underlying physics of the TMSR and posed five essential questions for classroom discussions. We assumed teachers had some preexisting knowledge of nuclear reactions, but such prior knowledge was not necessary for inclusion in the classroom discussions. Overall, our material was perceived as a real-world example of physics, fit into a standards-based curriculum, and filled a need in the teaching community for providing unbiased references of alternative energy technologies.

    Full Text Available The main objective of this study was the screening of some selected aromatic plants very popular in Greece, with respect to their total phenolic content, antioxidant capacity, reducing activity, and oxidative stability. All plants were extracted with the conventional method, reflux with methanol. The essential oils of the plants were also analyzed for their antioxidant properties. The total phenolic content was determined by the Folin-Ciocalteu method using gallic acid as the standard, while the phenolic substances were identified and quantified by High Performance Liquid Chromatography (HPLC coupled with a multi-wavelength ultraviolet-visible (UV-vis detector. The antioxidant capacity of the plant extracts was measured by their ability to scavenge free radicals such as (a DPPH (2,2-diphenyl-1-picrylhydrazyl and, (b ABTS (2,2′-azinobis-(3-ethylbenzothiaziline-6- sulfonate. The Folin-Ciocalteu method proved the existence of antioxidants in the aromatic plant extracts. Taking into account the results of the DPPH and ABTS methods, the free radical scavenging capacity was confirmed. Eventually, all plants exhibited low but noticeable protection levels against lipid oxidation, as determined by the Rancimat test.

    The ability to identify the manufacturers and distributors of chemicals seized in raids of illicit drug labs would be of great value in controlling the diversion of these chemicals. We developed a tagging scheme based on the addition of sub-ppM concentrations of various combinations of rare-earth elements to the target chemicals and evaluated a number of techniques for detecting the tags. We developed soluble tags for tagging liquids and selected Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) as the preferred detection technique. We developed insoluble tags for tagging solids and developed methods to analyze them and mix them into solid precursors. We have successfully demonstrated the tagging of several solvents and two of the precursor chemicals used in one of the most popular clandestine methamphetamine syntheses (ephedrine reacting with hydriodic acid/red phosphorus). The tagging scheme is capable of yielding tens of thousands of signatures (using holmium as an internal standard and up to 9 rare-earths at up to 3 concentrations yields 3{sup 9} {minus} 1 = 19,682 signatures) and is applicable to most of the chemicals on the precursor and essential chemicals list. In the concentrations employed, the tags are safe enough to be added to pharmaceuticals and cheap enough to tag tanker loads of chemicals.

    Workload Management System for Nursing (WMSN) is a core Army Medical Department business system that has provided near real-time, comprehensive nursing workload and manpower data for decision making at all levels for over 25 years. The Army Manpower Requirements and Documentation Agency populates data from WMSN into the Manpower Staffing Standards System (Inpatient module within Automated Staffing Assessment Model). The current system, Workload Management System for Nursing Internet (WMSNi), is an interim solution that requires additional functionalities for modernization and integration at the enterprise level. The expanding missions and approved requirements for WMSNi support strategic initiatives on the Army Medical Command balanced scorecard and require continued sustainment for multiple personnel and manpower business processes for both inpatient and outpatient nursing care. This system is currently being leveraged by the TRICARE Management Activity as an interim multiservice solution, and is being used at 24 Army medical treatment facilities. The evidenced-based information provided to Army decision makers through the methods used in the WMSNi will be essential across the Army Medical Command throughout the system's life cycle.

  18. Exploring the Optimal Strategy to Predict Essential Genes in Microbes

    Directory of Open Access Journals (Sweden)

    Yao Lu

    2011-12-01

    Full Text Available Accurately predicting essential genes is important in many aspects of biology, medicine and bioengineering. In previous research, we have developed a machine learning based integrative algorithm to predict essential genes in bacterial species. This algorithm lends itself to two approaches for predicting essential genes: learning the traits from known essential genes in the target organism, or transferring essential gene annotations from a closely related model organism. However, for an understudied microbe, each approach has its potential limitations. The first is constricted by the often small number of known essential genes. The second is limited by the availability of model organisms and by evolutionary distance. In this study, we aim to determine the optimal strategy for predicting essential genes by examining four microbes with well-characterized essential genes. Our results suggest that, unless the known essential genes are few, learning from the known essential genes in the target organism usually outperforms transferring essential gene annotations from a related model organism. In fact, the required number of known essential genes is surprisingly small to make accurate predictions. In prokaryotes, when the number of known essential genes is greater than 2% of total genes, this approach already comes close to its optimal performance. In eukaryotes, achieving the same best performance requires over 4% of total genes, reflecting the increased complexity of eukaryotic organisms. Combining the two approaches resulted in an increased performance when the known essential genes are few. Our investigation thus provides key information on accurately predicting essential genes and will greatly facilitate annotations of microbial genomes.

    Wagesho, Yohannes; Chandravanshi, Bhagwan Singh

    2015-01-01

    Ginger (Zingiber officinale Roscoe) is a common condiment for various foods and beverages and widely used worldwide as a spice. Its extracts are used extensively in the food, beverage, and confectionary industries in the production of products such as marmalade, pickles, chutney, ginger beer, ginger wine, liquors, biscuits, and other bakery products. In Ethiopia, it is among the important spices used in every kitchen to flavor stew, tea, bread and local alcoholic drinks. It is also chiefly used medicinally for indigestion, stomachache, malaria, fevers, common cold, and motion sickness. The literature survey revealed that there is no study conducted on the determination of metals in ginger cultivated in Ethiopia. Hence it is worthwhile to determine the levels of essential and non-essential metals in ginger cultivated in Ethiopia. The levels of essential (Ca, Mg, Fe, Zn, Cu, Co, Cr, Mn, and Ni) and non-essential (Cd and Pb) metals in ginger (Zingiber officinale Roscoe) cultivated in four different regions of Ethiopia and the soil where it was grown were determined by flame atomic absorption spectrometry. 0.5 g of oven dried ginger and soil samples were digested using 3 mL of HNO3 and 1 mL of HClO4 at 210°C for 3 h and a mixture of 6 mL aqua-regia and 1.5 mL H2O2 at 270°C for 3 h, respectively. The mean metal concentration (μg/g dry weight basis) ranged in the ginger and soil samples, respectively, were: Ca (2000-2540, 1770-3580), Mg (2700-4090, 1460-2440), Fe (41.8-89.0, 21700-46900), Zn (38.5-55.2, 255-412), Cu (1.1-4.8, 3.80-33.9), Co (2.0-7.6, 48.5-159), Cr (6.0-10.8, 110-163), Mn (184-401, 1760-6470), Ni (5.6-8.4, 14.1-79.3) and Cd (0.38-0.97, 0.24-1.1). The toxic metal Pb was not detected in both the ginger and soil samples. There was good correlation between some metals in ginger and soil samples while poor correlation between other metals (Fe, Ni, Cu). This study revealed that Ethiopian gingers are good source of essential metals and free from toxic

    2013-08-01

    Full Text Available Leaves of Echinodorus macrophyllus (Kunth Micheli, Alismataceae, were exposed to different doses of γ-radiation (0.00, 1.00, 3.00, 5.00, 10.00, and 20.00 kGy and the chemical composition of their essential oils was investigated. The extractive process of the essential oil was more favored when the leaves were irradiated. The essential oil components were identified by correlation between GC-FID data and retention parameters obtained from the Kováts method. Moreover, GC-MS analyses of the essential oils were correlated with fragmentation profiles in the NIST standard mass fragmentation data bank. The essential oil of E. macrophyllus contains biologically active constituents of different chemical classes. Acyclic monoterpenes and sesquiterpenes showed increase in concentration when the leaves were exposed to γ-radiation. On the other hand, the component concentrations of some chemical classes were lightly decreased, i.e., for bicyclic monoterpenes, diterpenes, triterpenes, carboxylic esters, and carotenoid derivatives.

    Full Text Available Essential oils from fresh Piperaceae leaves were obtained by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC–MS, and a total of 68 components were identified. Principal components analysis results showed a chemical variability between species, with sesquiterpene compounds predominating in the majority of species analyzed. The composition of the essential oil of Piper mosenii was described for the first time. The cytotoxicity of the essential oils was evaluated in peritoneal macrophages and the oils of P. rivinoides, P. arboretum, and P. aduncum exhibited the highest values, with cytotoxic concentration at 50% (CC50 > 200 µg/mL. Both P. diospyrifolium and P. aduncum displayed activity against Leishmania amazonensis, and were more selective for the parasite than for the macrophages, with a selectivity index (SI of 2.35 and >5.52, respectively. These SI values were greater than the 1 for the standard drug pentamidine. The antileishmanial activity of the essential oils of P. diospyrifolium and P. aduncum was described for the first time. P. rivinoides, P. cernuum, and P. diospyrifolium displayed moderate activity against the Mycobacterium tuberculosis H37Rv bacillus, with a minimum inhibitory concentration (MIC of 125 µg/mL. These results are relevant and suggests their potential for therapeutic purposes. Nevertheless, further studies are required to explain the exact mechanism of action of these essential oils.

The chemical constituents of essential oil from S mirzayanii were analyzed by gas chromatography-mass spectrometry. The antimicrobial activity was determined by broth microdilution. The main identified compounds were 1,8-cineole (41.2 ± 1.3%), linalool acetate (11.0 ± 0.5%), and α-terpinyl acetate (6.0 ± 0.4%) (mL of essential oil/g of plant material). The MIC 95 were 0.03 to 0.5 µL/mL and 16 to 128 µL/mL for gram-positive and gram-negative bacteria, respectively. These results indicated that Salvia mirzayanii essential oil significantly inhibited the growth of standard and clinically isolated tested yeasts by MIC 50 0.03 to 1 µL/mL. Potent antibacterial and antifungal activities of Salvia mirzayanii essential oil may be considered in future study, particularly against antibiotic-resistant cases.

    Full Text Available Objective: To evaluate the nutrients and essential oils of five medicinal plants, Juniperus excelsa (J. excelsa, Dodonaea viscosa, Euryops pinifolius, Teucrium polium (T. polium, and Helianthemum lippii that were collected from Jabal Al Akhdar, Oman. Methods: Proximate parameters (moisture, dry matter, ash, crude fats, proteins, fibers, nitrogen, carbohydrates, and energy values and nutrient analysis (K, Na, Ca, Fe, P, Mg etc. were evaluated in the five medicinal plants using standard techniques. On the basis of these analysis, T. polium and J. excels were selected for essential oil analysis using a rapid solvent-free microwave extraction method and GC-MS. Results: The results showed that leaves of J. excelsa had highest proportion of crude fats, fibers and energy value while ash was highest in T. polium. J. excelsa was also rich in essential minerals such as calcium, magnesium, potassium and iron while the trace elements and heavy metals composition was marginal. A rapid solvent-free microwave extraction method to extract oil from medicinal plants species showed that only T. polium and J. excelsa yielded oil. The chemical composition of essential oils showed higher proportion of delta-3-carene, limonene, β-eudesmol, ledeneoxide (II, α-trans-bergamatene, linalyl acetate and germacrene. Conclusions: J. excelsa and T. polium are a good source of proximate, minerals and essential oils, which can be considered for healthy life besides their medicinal values.

  4. Use of Essential Oils Following Traumatic Burn Injury: A Case Study.

    Jopke, Kathleen; Sanders, Heather; White-Traut, Rosemary

    Hospital admissions related to burn injury reach 40,000 annually. Patients who experience extensive burns require longer hospital stays and are at increased risk for infection and hospital acquired conditions. This comparative case study is a two patient matched case control design that follows the hospital course of two children who experienced burn injuries. For one of these patients, with the consent of the child's parents, the grandmother treated her granddaughter with essential oils. Essential oils have the potential to inhibit microbial growth, support treatment of wounds, and facilitate healing. However, there have been no large scale studies on essential oils. Data for the two cases were retrieved from the electronic medical record at a Midwestern Pediatric Hospital. Retrieved data included burn site description, treatment for burns, number of days on the ventilator, white blood cell count, length of hospital stay, number of ICU days, infections diagnosed by positive culture and pain ratings. While the goals for treatment were the same for both children, the child who received only standard care was diagnosed with two blood stream infections and four hospital acquired conditions while the child who received supplemental treatment with essential oils did not develop any blood stream infections, was diagnosed with one hospital acquired condition, was in the PICU one day less, and had a four day shorter length of hospital stay. While these case findings are intriguing, research is needed to expand understanding of the role of essential oils in the treatment of burns. Copyright © 2017 Elsevier Inc. All rights reserved.

    Essential oils from fresh Piperaceae leaves were obtained by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC-MS), and a total of 68 components were identified. Principal components analysis results showed a chemical variability between species, with sesquiterpene compounds predominating in the majority of species analyzed. The composition of the essential oil of Piper mosenii was described for the first time. The cytotoxicity of the essential oils was evaluated in peritoneal macrophages and the oils of P. rivinoides , P. arboretum , and P. aduncum exhibited the highest values, with cytotoxic concentration at 50% (CC 50 ) > 200 µg/mL. Both P. diospyrifolium and P. aduncum displayed activity against Leishmania amazonensis , and were more selective for the parasite than for the macrophages, with a selectivity index (SI) of 2.35 and >5.52, respectively. These SI values were greater than the 1 for the standard drug pentamidine. The antileishmanial activity of the essential oils of P. diospyrifolium and P. aduncum was described for the first time. P. rivinoides, P. cernuum , and P. diospyrifolium displayed moderate activity against the Mycobacterium tuberculosis H 37 Rv bacillus, with a minimum inhibitory concentration (MIC) of 125 µg/mL. These results are relevant and suggests their potential for therapeutic purposes. Nevertheless, further studies are required to explain the exact mechanism of action of these essential oils.

    Essential genes are indispensable for the survival of an organism in optimal conditions. Rapid and accurate identifications of new essential genes are of great theoretical and practical significance. Exploring features with predictive power is fundamental for this. Here, we calculate six fractal features from primary gene and protein sequences and then explore their relationship with gene essentiality by statistical analysis and machine learning-based methods. The models are applied to all the currently available identified genes in 27 bacteria from the database of essential genes (DEG). It is found that the fractal features of essential genes generally differ from those of non-essential genes. The fractal features are used to ascertain the parameters of two machine learning classifiers: Naïve Bayes and Random Forest. The area under the curve (AUC) of both classifiers show that each fractal feature is satisfactorily discriminative between essential genes and non-essential genes individually. And, although significant correlations exist among fractal features, gene essentiality can also be reliably predicted by various combinations of them. Thus, the fractal features analyzed in our study can be used not only to construct a good essentiality classifier alone, but also to be significant contributors for computational tools identifying essential genes.

    Essential oils are concentrated liquids of complex mixtures of volatile compounds and can be extracted from several plant organs. Essential oils are a good source of several bioactive compounds, which possess antioxidative and antimicrobial properties. In addition, some essential oils have been used as medicine. Furthermore, the uses of essential oils have received increasing attention as the natural additives for the shelf-life extension of food products, due to the risk in using synthetic preservatives. Essential oils can be incorporated into packaging, in which they can provide multifunctions termed "active or smart packaging." Those essential oils are able to modify the matrix of packaging materials, thereby rendering the improved properties. This review covers up-to-date literatures on essential oils including sources, chemical composition, extraction methods, bioactivities, and their applications, particularly with the emphasis on preservation and the shelf-life extension of food products. © 2014 Institute of Food Technologists®

    Full Text Available In 1929 Burr and Burr discovered the essential fatty acids omega-6 and omega-3. Since then, researchers have shown a growing interest in polyunsaturated fatty acids (PUFA as precursors of “lipid mediator” molecules, often with opposing effects, prostaglandins, prostacyclins, thromboxanes, leukotrienes, lipossines, resolvines, protectines, maresins that regulate immunity, platelet aggregation, inflammation, etc. They showed that the balance between omega-3 and omega-6 acids has a profound influence on all the body’s inflammatory responses and a raised level of PUFA omega-3 in tissue correlate with a reduced incidence of degenerative cardiovascular disease, some mental illnesses such as depression, and neuro-degenerative diseases such as Alzheimer’s. The CYP-catalyzed epoxidation and hydroxylation of arachidonic acid (AA were established recently as the so-called third branch of AGE cascade. Cytochrome P450 (CYP epoxygenases convert AA to four epoxyeicosatrienoic acid (EET regioisomers, that produce vascular relaxation anti-inflammatory effects on blood vessels and in the kidney, promote angiogenesis, and protect ischemic myocardium and brain. Eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA are accessible to CYP enzymes in the same way as AA. Metabolites derived from EPA include epoxyeicosatetraenoic acids (EETR and hydroxyeicosapentaenoic acids (19- and 20-HEPE, whereas DHA include epoxydocosapentaenoic acids (EDPs hydroxydocosahexaenoic acids (21- and 22-HDoHE. For many of the CYP isoforms, the n-3 PUFAs are the preferred substrates and the available data suggest that some of the vasculo- and cardioprotective effects attributed to dietary n-3 PUFAs may be mediated by CYP-dependent metabolites of EPA and DHA. From AA derives also endocannabinoids like anandamide (N-arachidonoylethanolamine and 2-arachidonoylglycerol, capable of mimicking the pharmacological actions of the active principle of Cannabis sativa preparations such as

    Full text: Increased life expectancy has markedly enhanced the need for biomedical devices to combat life-threatening conditions (e.g., pacemakers, artificial blood vessels) or improve the quality of life (e.g., intraocular lenses, artificial ligaments, contact lenses). While the biomedical device industry has delivered remarkable benefits, many existing and emerging needs and applications are not adequately met with existing synthetic materials. Depending on the application, a biomaterial needs to meet a number of requirements to be `biocompatible`, such as appropriate mechanical properties, transparency, resistance to enzymatic degradation, and appropriate biological responses by the host environment. Surface science and surface analysis plays a key role in understanding and optimizing the molecular interfacial interactions between synthetic materials surfaces and biological media which lead to biological responses to implants. Many biological molecules such as proteins and lipids have surfactant activity and respond to interfaces on contact. Thus, an important part of achieving `biocompatibility` is to produce an appropriate surface chemical composition that avoids undesirable biological consequences triggered by biological molecules recognizing a `foreign` material interface. XPS surface analysis has proved uniquely suitable for studying several aspects of biomaterials. In order to interpret biological responses in terms of surface chemistry, it is essential that the surface be well characterized. However, for polymers this can be quite a challenge due to the inherent mobility of polymer chains. For instance, polyurethanes present a surface chemistry that differs from the `bulk` chemistry. It is often desirable to utilize a bulk material with desirable bulk properties and improve its biocompatibility by the application of a surface modification or a thin coating. XPS has been used to verify the intended coating chemistry and the uniformity of thin coatings. On

    To suggest important methodological considerations when using grounded theory. A research method widely used in nursing research is grounded theory, at the centre of which is theory construction. However, researchers still struggle with some of its methodological issues. Although grounded theory is widely used to study and explain issues in nursing practice, many researchers are still failing to adhere to its rigorous standards. Researchers should articulate the focus of their investigations - the substantive area of interest as well as the focal population. This should be followed by a succinct explanation of the strategies used to collect and analyse data, supported by clear coding processes. Finally, the resolution of the core issues, including the core category and related categories, should be explained to advance readers' understanding. Researchers should endeavour to understand the tenets of grounded theory. This enables 'neophytes' in particular to make methodological decisions that will improve their studies' rigour and fit with grounded theory. This paper complements the current dialogue on improving the understanding of grounded theory methodology in nursing research. The paper also suggests important procedural decisions researchers need to make to preserve their studies' scientific merit and fit with grounded theory.

    The compositions of mountain pine (Pinus uncinata) and peat-bog pine (P. uliginosa) needle essential oils were investigated. Enantiomeric compositions of selected monoterpene hydrocarbons were also examined. Respectively, fifty-three and seventy-six components of the essential oils were identified using GC-MS and retention indexes. The main group of essential oil components of mountain pine needles were monoterpenes, and bornyl acetate constituted approximately 30% (46.3 g/100 g) of the oil. In peat-bog pine essential oil, monoterpenes and sesquiterpenes exhibited a similar content (ca. 40%). Bornyl acetate and α-pinene were the main constituents of both essential oils. In the essential oil of P. uncinata needles, limonene, camphene, myrcene and (E)-β-caryophyllene were also noticeable, while in the essential oil of P. uliginosa needles, Δ-car-3-ene, (E)-β-caryophyllene, germacrene D, δ-cadinene, germacrene D 4-ol and α-cadinol were present in notable quantities. In both essential oils, borneol propionate, isobutyrate, 2-methylbutyrate and isovalerate were detected. Their presence was confirmed by synthesis and analysis of the standards; retention indexes on a non-polar column are published herein.

In ISO, there are new standards being completed and old ones (some of which are not really all that old) being revised. As you`ll be hearing, there is lots of SGML activity in the applications world--particularly on the Internet--and that`s causing other kinds of standards activity. WG8 divides its work into five ``Rapporteur Groups`` (or ``RGs``) for DSSSL, Font Description and Interchange, SGML, SPDL, and Hypermedia Languages. Since interest is in DSSSL, SGML, and Hypermedia Languages, the author only mentions that the other groups have been active, too. The Fronts group has been doing amendments to its standards, ISO/IEC 9541 and ISO/IEC 10036. The Fronts groups has been active in providing support for ISO/IEC 10646, the massive character coding standard that has drawn a lot of attention in the SGML world. The SPDL group has at long last finished its standard, the Standard Page Description Language (ISO/IEC 10180) and is about to publish it. More detailed discussions are given for activity in SGML, DSSSL, and Hypermedia Languages.

    This presentation provides an overview of the current status of the ISO radiation sterilization standards. The ISO standards are voluntary standards which detail both the validation and routine control of the sterilization process. ISO 11137 was approved in 1994 and published in 1995. When reviewing the standard you will note that less than 20% of the standard is devoted to requirements and the remainder is guidance on how to comply with the requirements. Future standards developments in radiation sterilization are being focused on providing additional guidance. The guidance that is currently provided in informative annexes of ISO 11137 includes: device/packaging materials, dose setting methods, and dosimeters and dose measurement, currently, there are four Technical Reports being developed to provide additional guidance: 1. AAMI Draft TIR, 'Radiation Sterilization Material Qualification' 2. ISO TR 13409-1996, 'Sterilization of health care products - Radiation sterilization - Substantiation of 25 kGy as a sterilization dose for small or infrequent production batches' 3. ISO Draft TR, 'Sterilization of health care products - Radiation sterilization Selection of a sterilization dose for a single production batch' 4. ISO Draft TR, 'Sterilization of health care products - Radiation sterilization-Product Families, Plans for Sampling and Frequency of Dose Audits'

  20. Assessing the Genetics Content in the Next Generation Science Standards.

    Full Text Available Science standards have a long history in the United States and currently form the backbone of efforts to improve primary and secondary education in science, technology, engineering, and math (STEM. Although there has been much political controversy over the influence of standards on teacher autonomy and student performance, little light has been shed on how well standards cover science content. We assessed the coverage of genetics content in the Next Generation Science Standards (NGSS using a consensus list of American Society of Human Genetics (ASHG core concepts. We also compared the NGSS against state science standards. Our goals were to assess the potential of the new standards to support genetic literacy and to determine if they improve the coverage of genetics concepts relative to state standards. We found that expert reviewers cannot identify ASHG core concepts within the new standards with high reliability, suggesting that the scope of content addressed by the standards may be inconsistently interpreted. Given results that indicate that the disciplinary core ideas (DCIs included in the NGSS documents produced by Achieve, Inc. clarify the content covered by the standards statements themselves, we recommend that the NGSS standards statements always be viewed alongside their supporting disciplinary core ideas. In addition, gaps exist in the coverage of essential genetics concepts, most worryingly concepts dealing with patterns of inheritance, both Mendelian and complex. Finally, state standards vary widely in their coverage of genetics concepts when compared with the NGSS. On average, however, the NGSS support genetic literacy better than extant state standards.
