    The aim of the present study was to survey the validation of the Georgian version of "Oral Health Impact Profile" (OHIP). Initial testing of questionnaire showed that the all questions are understood by the patients. Survey, which was conducted with the help of the Georgian version of quality of life questionnaire, showed that received results are directed related to the progress of chronic parodontitis; during the aggravation period there is the worse quality of life than those in remission. It was confirmed that the Georgian version of the questionnaire reflects the objective side of the disease. The influence of the objective and subjective parameters on the quality of life show the average power ratios of positive correlation received by us between the quality of life and main clinical index, which is typical for parodontitis progress (CPI). During improving the clinical picture of the disease there is revealed the reduction of both, the CPI and the number of scores. Numerous studies have shown that the OHIP questionnaire was tested and accepted in different countries of the world, but until recently there were no Georgian version of the questionnaire. Questionnaire (OHIP) contains only 14 questions, which gives the patient an opportunity to quickly complete it, and the doctor - to quickly assess the results of the application. The data obtained can be used as a treatment planning, as well as during provided examination of the quality of the medical services. Based on the obtained data, we can plan not only therapeutic measures, but also to identify the need of psychological help of patients.

    The history of paediatrics and child health is increasingly recognised to be about children themselves and how they and their families cope and adapt to their medical condition rather than about medical practitioners and august institutions. This article considers two case studies, showing how two Georgian fathers cared for their children when sickness struck and their reactions when the children died. Davies (Giddy) Gilbert, FRS (1767-1840), was a member of Parliament first for Helston and later for Bodmin. (He married Ann Mary Gilbert in 1808 and formally changed his name to Gilbert; the change received royal approbation in January 1817.) Gilbert recorded the birth and development of his son Charles (1810-1813), in one of the very earliest developmental chronicles. He regularly recorded his child's progress, including height, weight, social interaction, communication skills and speech. Apparently in good health for most of his life, Charles developed an acute abdominal disorder and died unexpectedly. John Tremayne (1780-1851) was a member of Parliament for Cornwall. His son Harry (1814-1823) had increasing bilious attacks, headaches and a squint from the age of 6 years, and died despite the best medical advice available. Current medical opinion would presume an intracranial tumour. Tremayne graphically expressed his pain as he closely observed his son suffer, apparently as much from the treatments as from the disease itself. This study sheds light on clinical aspects of Georgian medical practice, the medical marketplace and the nature of relationships between these fathers and their children.

    Full Text Available Georgian monetary relations have a centuries-old history. Credit associations were first founded in 11-13th centuries. Network of credit institutions became larger in the 19th century – independent commercial banks were established in the second half of the 19th century. Central State Bank of Georgia was established in the Democratic Republic of Georgia in the beginning of the 20th century. At the same time, there were efforts to create independent two-level banking system, although those efforts failed due to forceful sovietization of Georgia. But still, independent banking system was founded in Georgia after the collapse of the former Soviet Union. This work examines afore-mentioned evolutionary processes and some of peculiarities of modern banking system. The research shows that modern Georgian banking system is growing fast but it contains signs of oligopoly which contradicts the interests of vast masses of population and entrepreneurial development, while stimulating retaining of high interest rates and devaluation of national currency.

    Full Text Available The potential of the Georgian wine industry is not fully utilized. High fragmentation of agricultural land leads to limited production that restricts farmers' access to capital resources, finances, and markets, and prevents further development of the Georgian wine industry. Grape collectors and wine makers need help to join their capital and efforts, to gain economies of scale in production and marketing by jointly accessing agricultural inputs. This study aims to identify the importance of farmer cooperatives for grape producers in the Georgian wine industry in order to overcome inefficiency in the sector. Furthermore, this research project investigates the barriers and driving forces of smallholder grape farmers or wine makers to join cooperatives. Semi-structured interviews were conducted with stakeholders of the Georgian wine industry in order to assess different perspectives on the importance and benefits of farmer cooperatives in the local context. The interview results permit economic analysis of transaction costs, agency theory and property rights in the context of the nascent cooperative movement in the Georgian wine industry. The interviews revealed that development of agriculture cooperatives in the Georgian wine industry is strongly dependent on both farmer enthusiasm and governmental support.1

    2015-01-01

    This article explores the reception of some anatomical collections in Georgian and Victorian England. Both private medical museums and public anatomical museums reflected the central role played by anatomy in medical knowledge and education in the eighteenth and nineteenth centuries. However, because they were associated with death and sexuality, anatomical museums were both products of enlightenment science and potentially immoral loci likely to corrupt young and innocent women. But, as this article shows, the reasons behind the hostile receptions of some collections varied throughout the centuries, revealing in so doing the gradual professionalization of the medical field and growing monopoly of medical professionals over medical knowledge.

    Full Text Available With the ever-increasing volume of applications of various kinds of electric drives in all spheres of human activity, the issues in improving the efficiency of the electromechanical converters of electric energy, one of the most important components of the electric drive (ED, are becoming increasingly important. Such issues include reducing their weight and size, improving the functional characteristics of these devices to increase their operational life and reducing the cost of manufacture. Taking full advantage of these opportunities relates to the AC and DC single-phase commutator motor (SCM, which is widely used in regulated and high-speed motor drives in medical electric hand tools. The SCM is used in machinery where the load torque has a hyperbolic dependence on the rotational speed and the need to work with a large motor overload due to the “soft” mechanical characteristics of such motors.

    Mário C.G. Ramos

    2009-01-01

    Full Text Available Problem statement: Medical electrical equipments at health care facilities presented malfunction and wrong medical information due to poor electric power quality and to inadequate electrical Installations. Some equipment such as X-ray, computerized axial tomography and magnetic resonance imaging are considered as polluting ones due to their high amount of harmonics and voltage transients produced on the electrical power supply when in operation, while other equipments, connected to the same power supply, are considered sensitive or victim ones, presenting failure or producing wrong. Approach: The effects on some sensitive medical electrical equipment were verified in a controlled environment at energy quality technological center of the technical school of the University of Sao Paulo. A heart monitor, pulmonary ventilator and pulse oxymeter equipment types were submitted to a controlled voltage supply with high harmonic content and voltage sags. The test methodology used simulated conditions based on Brazilian NBR standards, ANSI/IEEE Std. 519, IEC 60601 and IEC 61000-4-11 standards. Results: The results of the polluting equipment current consumption measurements as well as the three sensitive equipments tested were presented and discussed. The pulmonary ventilator presented problems that range from stoppage to expiratory valve blockage and alarm system failures. The pulse oxymeter presented display malfunctions and it was extremely sensitive to voltage sags. The heart monitor maintained steady operation in all test cases. Conclusion/Recommendations: In spite of several existing recommendations and standards for testing medical electrical equipments, there is a lack of standard related to test cases considering the effects of high harmonic and voltage sags. The quality of electrical installation in health care facilities needs to be improved to reduce risks to the patients and to provide better health treatment.

    Full Text Available In the former Soviet Union the economy of the Georgian Republic occupied advanced positions. At the very first stage of the restoration of independence the post-Soviet Georgia’s economy declined 3-times; in the following years, the situation improved, but it reached the 1990 level only after 15 years. In spite of difficult problems of development it should be singled out the middle period progress of the 90-ies when the country introduced a new currency - Lari, created conditions for attracting foreign investments, economic growth was expressed in double-digit figures; it created an independent banking system, rapidly implemented the program of privatization, strengthened the links with international financial organizations and others. By this time, the private sector’s share in the state budget revenues was already 80%. After the end of the 90-ies, in a few years, economic reforms stalled. After the “Rose Revolution” - until 2012, the development of economy was greatly influenced by tightened administrative methods, foreign loans, foreign investment, and so forth. Unfortunately, at this stage of development, a property encroachment for the government became common practice in such a way as pressure on business. In recent four years, more attention was paid to the actual development, deepening of integration with European Union, the governmental pressure on business was removed. However, because of the lack of jobs, labour force continues to flow abroad.

    Implantable medical devices (IMDs) are crit-ically requested for the survival of patients subject to certain serious diseases such as bradycardia, fibrillation, diabetes, and disability, etc. Appropriate working of an active implantable medical device (IMD) heavily relies on the continuous supply of electricity. In this sense, long-term powering and recharging of an IMD via a highly safe, efficient and convenient way is, therefore, extremely important in clinics. Several conventional batteries, such as lithium cell, nuclear cell and bio-fuel cell, etc., have been developed to power IMDs. Meanwhile, the recharge of IMD from outside of the human body is also under investigation. In this paper, some of the most typical IMD batteries are reviewed. Their advantages and disadvantages are compared. In addition, several emer-ging innovations to recharge or directly drive the implanted batteries, including electromagnetic energy transmission, piezoelectric power generation, thermoelec-tric devices, ultrasonic power motors, radio frequency recharging and optical recharging methods, etc., are also discussed. Some fundamental and practical issues thus involved are summarized, and future prospects in this area are made.

    2017-01-01

    One method for three-dimensional (3D) measurement based on structured light is proposed for the medical electric endoscope in the present study. The structured light of black and white strips is generated by that the point sources illuminate the grating mask plate. Four point sources are aligned linearly by a certain space and they are lighted sequentially. Then four images of modulated fringes by the height of object with different phase shifts can be obtained. The algorithm proposed by Wang Z is employed to extract the accurate phase shift from the fringe images since the phase shift cannot be exactly set as π/2 by hardware. An experimental prototype endoscope was built according to the proposed method. One high-definition CMOS camera module developed by ourselves was used to acquire the endoscopic images and the structured light was generated by four fiber LEDs and a transmission grating with a pitch of 0.1 mm. one C# program was designed to light up LEDs in turn, acquire the phase shifted images and calculate the 3D information. The experimental results indicate that its precise of depth measurement at the working distance of 40 mm is better than 0.5 mm and its consuming time of 3D depth calculation is less than 0.5 s.

    The objective of the present study was to develop the criteria for forensic-medical diagnostics of an electrical injury inflicted in the aqueous environment based on the characteristics of the electrical mark. The specific morphological features of the electrical injuries inflicted in the aqueous environment that were discovered in the materials available for the forensic medical expertise were analysed taking into consideration the results of the relevant research reported in the forensic medical literature. It was shown that an electrical injury inflicted in the aqueous environment results in the formation of an unusual mark in the form of blisters containing no watery liquid associated with electrogenic oedema in the surrounding tissues. Macroscopic and microscopic studies of the electrical mark failed to reveal the signs of grade III and IV grade thermal burning or thermally affected hair. It is concluded that the consistent characteristics of the electrical mark resulting from the injury inflicted by technical electricity in the aqueous environment include cell lengthening, blister formation inside the corneal layer, and the separation of epidermis from the skin proper.

    A novel non-contact controller of the electric bed for medical healthcare was proposed in this study. Nowadays, the electric beds are widely used for hospitals and home-care, and the conventional control method of the electric beds usually involves in the manual operation. However, it is more difficult for the disabled and bedridden patients, who might totally depend on others, to operate the conventional electric beds by themselves. Different from the current controlling method, the proposed system provides a new concept of controlling the electric bed via visual stimuli, without manual operation. The disabled patients could operate the electric bed by focusing on the control icons of a visual stimulus tablet in the proposed system. Besides, a wearable and wireless EEG acquisition module was also implemented to monitor the EEG signals of patients. The experimental results showed that the proposed system successfully measured and extracted the EEG features related to visual stimuli, and the disabled patients could operate the adjustable function of the electric bed by themselves to effectively reduce the long-term care burden.

    Full Text Available Globalization - a complex system of innovation, internationalization and rapidly growing interdependence – plays the greatest role in the formation of today’s world. It enters different spheres of human life and stipulates the uniformity of economy, law, business and even, political life. In the framework of global processes, a lot of changes can be seen in the legal systems of European countries. The given paper discusses the formation of the Romanian “fiducia” and the Georgian “საკუთრების მინდობა” (sakutrebis mindoba – means “trust” under the influence of Anglo-American “trust”. The term “trust” generally nominates an institution of Anglo-American law, which is irreplaceable in the cases when the real owner of the property must be substituted by the nominal one (trustee for carrying out civil relationships. This concept originated in the English Common law, but has been constantly rejected by the European continental legal systems (Civil law. The main obstacle laid in the fact, that Anglo-American legal system was based on the duality of ownership, which was almost unacceptable for the continental law-governed countries. However, in the recent years, the growing importance of the American capital markets popularized the utilization of “trust” and stipulated its insertion in some “rigid” European jurisdictions. Moreover, some world countries have already indirectly allowed mechanisms similar to the “trust”. Among them are Romania and Georgia. The given research is dedicated to the precise description of the Romanian and Georgian “trust instruments”. It singles out major terminological units and underlines the fact that newly-established mechanisms have to undergo several stages for turning into faithful reflections of the original model of “trust”.

    2015-03-01

    TASER(®) conducted electrical weapons (CEWs) have become an important law-enforcement tool. Controversial questions are often raised during discussion of some incidents in which the devices have been used. The main purpose of this paper is to point out some misconceptions about CEWs that have been published in the scientific/medical and other literature. This is a narrative review, using a multidisciplinary approach of analyzing reports from scientific/medical and other literature sources. In previous reports, durations of incapacitating effects and possible associations of CEWs with deaths-in-custody have often been overstated or exaggerated. Comparisons of CEW effects with "electrocution" are misleading. Clarification of these misconceptions may be important during policymaker decisions, practitioner operations, expert witness testimonies, and court proceedings. Despite misconceptions in the literature, CEWs can still be a valuable tool for law enforcement activities. Scientists, medical professionals, legal advisors, and investigators of police tactics should be aware of these misconceptions.

    Inherited thrombophilia means a predisposition of an individual to thrombosis caused by genetic disorders of homeostasis system. Purpose of the conducted study was to establish the role of point mutations of prothrombin (PGM) - 20210G/A; Factor V Leiden (FVL) - 1691G/A and methylenetetrahydrofolate reductase (MTHFR) - 677C/T genes, i.e. inherited thrombophilia in the pathogenesis of primary and recurrent venous thromboembolism in patients of the Georgian population. The above mentioned mutations were detected by PCR and single nucleotide primer extension reaction, followed by Enzyme Linked Immuno-Sorbent Assay (ELISA) in 93 patients with venous thromboembolism, out of which: 56 patients were diagnosed with unprovoked, primary thromboembolism confirmed by objective studies and 37 patients were diagnosed with recurrent thromboembolism. According to statistical analysis of the results, incidence of FVL mutation in the group of patients with recurrent thrombosis was significantly higher compared to patients with primary thrombosis - respectively 0.21 and 0.44 (p=0.0164<0.05). It should also be mentioned that homozygous carriage of FVL mutation was confirmed only with patients having recurrent thrombosis. Similar tendency was observed during study of prothrombin gene; however the difference was not statistically significant. Similar tendencies were not observed in case of homozygous carriage of MTHFR gene C677T mutation. Double and triple heterozygous/homozygous carriage of studied mutations (total of 20 cases) was observed in patients of both groups. Distribution of these genotypes in the recurrent thrombosis group was higher compared to patients with primary thrombosis - respectively 27% and 17.9%. Herewith, it should be mentioned that the patients with primary thrombosis were much younger than those with recurrent thrombosis and their age did not exceed 50 years. According to the results obtained by us, it is possible to consider Leiden mutation, especially its

    Full Text Available Abstract Background Georgia's health care system underwent dramatic reform after gaining independence in 1991. The decentralization of the health care system was one of the core elements of health care reform but reports suggest that human resource management issues were overlooked. The Georgian national immunization program was affected by these reforms and is not functioning at optimum levels. This paper describes the state of human resource management practices within the Georgian national immunization program in late 2004. Methods Thirty districts were selected for the study. Within these districts, 392 providers and thirty immunization managers participated in the study. Survey questionnaires were administered through face-to-face interviews to immunization managers and a mail survey was administered to immunization providers. Qualitative data collection involved four focus groups. Analysis of variance (ANOVA and Chi-square tests were used to test for differences between groups for continuous and categorical variables. Content analysis identified main themes within the focus groups. Results Weak administrative links exist between the Centres of Public Health (CPH and Primary Health Care (PHC health facilities. There is a lack of clear management guidelines and only 49.6% of all health providers had written job descriptions. A common concern among all respondents was the extremely inadequate salary. Managers cited lack of authority and poor knowledge and skills in human resource management. Lack of resources and infrastructure were identified as major barriers to improving immunization. Conclusion Our study found that the National Immunization Program in Georgia was characterized by weak organizational structure and processes and a lack of knowledge and skills in management and supervision, especially at peripheral levels. The development of the skills and processes of a well-managed workforce may help improve immunization rates, facilitate

  10. The 'electric stroke' and the 'electric spark': anatomists and eroticism at George Baker's electric eel exhibition in 1776 and 1777.

    2010-09-01

    In 1776 and 1777 five living electric eels exhibited in London became a sensational spectacle that appealed to anatomists, electricians and connoisseurs of erotica. George Baker's exhibition made visible the 'electric spark' of the electrical eel and a series of experiments were both witnessed by and participated in by members of the Royal Society and the metropolitan elite. Some participants even grasped the eels firmly in their hands and felt the 'electric stroke' of the eel in addition to observing the spark. In their observation of the electric eel some of these spectators transposed the vivid electric spark from the sphere of electricians and anatomists into that of satirical and erotic literature. Here the erotic electric eel proliferated in the literature and the eel took on quite different connotations that nonetheless were reliant on readers knowledge and experience of the exhibition, experiments and the preoccupations of anatomists. George Baker's electric eel exhibition of 1776 and 1777 is then instructive in exploring the production and circulation of knowledge in Georgian Britain. The story of the electric eel in Georgian culture charts the creation of the electric spark and stroke as objects of observation and encounter, their exhibitionary context, and finally their divergent meanings as the electric eel became erotically charged for a metropolitan masculine elite.

After the improvement, we not only have more effective detection of the electrical safety performance of all kinds of medical electrical equipment, but also reduce the workload of clinical engineers, improve efficiency, and reduce the risk of electrical shock.

  12. Ethos without nomos: the Russian–Georgian War and the post-Soviet state of exception

    Full Text Available This paper addresses the 2008 Russian–Georgian conflict in the context of the post-Soviet spatial order, approached in terms of Carl Schmitt's theory of nomos and Giorgio Agamben's theory of the state of exception. The ‘five-day war’ was the first instance of the violation by Russia of the integrity of the post-Soviet spatial order established in the Belovezha treaties of December 1991. While from the beginning of the postcommunist period Russia functioned as the restraining force in the post-Soviet realm, the 2008 war has made further recourse to this function impossible, plunging the post-Soviet space into the condition of anomie, or the state of exception. This paper interprets this disruptive policy in the post-Soviet space as the continuation of the domestic political process of the ‘management of anomie,’ which has characterized the entire postcommunist period. In the conclusion, we address the implications of the transformation of the international order into the ethos of anomie for rethinking the ethical dimension of global politics.

  13. The Covent Garden Old Price Riots: Protest and Justice in Late‑Georgian London

    Full Text Available This article explores perceptions of the law and of how agents of the law responded to events at Covent Garden Theatre during the bitter months between mid-October and late-November 1809, the height of the Covent Garden Old Price riots. It does so through the lens of the periodical press, a vital and voluminous source of not only what happened during the riots but also of opinions on what happened and of perceptions of what happened, opinions and perceptions that are the primary concern of this article. The article begins with a discussion of how the magistrates, ‘police officers,’ justices, and lawyers who together were agents of the legal system were seen, where they were seen, and what they did. It moves on to examine how the actions of those agents and the legal system they represented were reported upon. And it concludes with a discussion of how theatregoers and Londoners were seen to have responded to those actions, moving a significant element of the conflict outside of Covent Garden Theatre and into the public press in a direct response to how they were policed as threats to public order and security. It argues that the Covent Garden Old Price riots was a significant urban act of multi-class protest because of the ways that it intersected with wider late-Georgian concerns, with discursive arenas where British liberty and the freedom of her subjects were contested and at stake.

    Full Text Available Vibrio parahaemolyticus is a leading cause of seafood-related gastroenteritis and is also an autochthonous member of marine and estuarine environments worldwide. One hundred seventy strains of V. parahaemolyticus were isolated from water and plankton samples collected along the Georgian coast of the Black Sea during 28 months of sample collection. All isolated strains were tested for presence of tlh, trh, and tdh. A subset of strains were serotyped and tested for additional factors and markers of pandemicity. Twenty-six serotypes, five of which are clinically relevant, were identified. Although all 170 isolates were negative for tdh, trh, and the Kanagawa Phenomenon, 7 possessed the GS-PCR sequence and 27 the 850 bp sequence of V. parahaemolyticus pandemic strains. The V. parahaemolyticus population in the Black Sea was estimated to be genomically heterogeneous by rep-PCR and the serodiversity observed did not correlate with rep-PCR genomic diversity. Statistical modeling was used to predict presence of V. parahaemolyticus as a function of water temperature, with strongest concordance observed for Green Cape site samples (Percent of total variance = 70, P < 0.001. Results demonstrate a diverse population of V. parahaemolyticus in the Black Sea, some of which carry pandemic markers, with increased water temperature correlated to an increase in abundance of V. parahaemolyticus.

    The yeast microbiota present in wines produced by the ancient "Kakhetian" method in Georgia (EU) was studied. This technique involves the use of terracotta vessels (amphoras), during spontaneous fermentation, maceration phase and wine ageing. The analysed yeasts were collected from wines after maturation for one year in ten amphoras from a Georgian winery. The 260 isolates were all identified as Saccharomyces cerevisiae, and the majority were classified as flor yeasts by restriction analysis of ITS region. A first technological and molecular screening was used to select 70 strains for further characterization. Both genetic and metabolic characterization discriminated flor from non-flor strains. The combined results obtained by analysis of interdelta region and mtDNA-RFLP yielded 23 different biotypes; no biotype was common to flor and non-flor strains. The wines produced by flor yeasts showed a high content in acetaldehyde, acetic acid, acetoin, whereas the level of other compounds was similar to wines obtained by non-flor strains. This study represents the first report on the composition of yeast microbiota involved in the maturation of this traditional wine. These flor strains represent an interesting yeast population, in possession of peculiar characteristics allowing them to survive during wine ageing, becoming the dominant flora in the final wine.

    he medical electric and electronic equipment, including electro surgical devices, short- and microwave diathermy units, and magnetic resonance imaging (MRI) systems, belong to the most hazardous sources of electromagnetic emissions. The electromagnetic emissions can interfere with emissions from other medical equipment located in the same facility (e.g. operation rooms) thus having impact on their work, but more importantly, they can be dangerous to patients, medical personnel operating them and other persons. In the present project, an assessment of E.M.F. intensity was performed for more than 2 000 electro surgical devices (330 khz, 440 khz and 1.76 MHz frequency ranges), 1 200 diathermy units and 45 MRI 0.2 - 1.5 T systems. E.M.F. exposure of medical staff was assessed based on respective national hygienic standards. The actual exposure levels were found to exceed the admissible values in Poland. The recorded E.M.F. intensities were compared with relevant Who and U E recommendations (e.g. I.C.N.I.R.P. guidelines, 1998, Directive 2004/40/E.C.). The findings revealed that for 18% of the devices examined, the E.M.F. was higher than the E.M.F. intensity values recommended by U E. (authors)

    2009-09-01

    We used a GIS-based approach to examine the influence of road density and physical watershed features (watershed size, wetland cover, and bedrock type) on water quality in coastal marshes of Georgian Bay, Ontario. We created a GIS that included landscape information and water-quality data from a 9-year synoptic survey of 105 coastal marshes covering 28 quaternary watersheds. Multiple regressions and partial correlations were used to discern confounding effects of human-induced (road density) versus natural physical watershed determinants of water quality. Road density was the dominant factor influencing many water quality variables, showing positive correlations with specific conductivity (COND), total suspended solids (TSS), and inorganic suspended solids (ISS) and a negative correlation with overall Water Quality Index scores. Road density also showed positive correlations with total nitrate nitrogen (TNN) and total phosphorus (TP). By comparison, larger watershed area was the main factor leading to elevated TP concentrations. The proportion of the watershed occupied by wetlands explained the largest amount of variation in TNN concentrations (negative correlation) and was also negatively correlated with COND and positively correlated with TSS and ISS when we controlled for road density. Bedrock type did not have a significant effect in any of the models. Our findings suggest that road density is currently the overriding factor governing water quality of coastal marshes in Georgian Bay during the summer low-flow period. We recommend that natural variation in physical watershed characteristics be considered when developing water quality standards and management practices for freshwater coastal areas.

  18. THE CONCEPT OF “TESTATE SUCCESSION” IN THE ROMANIAN AND GEORGIAN LEGAL SYSTEMS (TERMINOLOGICAL SIMILARITIES AND DIFFERENCES

    Full Text Available The death of an individual never causes an automatic termination of his (her rights and obligations. They are transferred to his (her descendants. The permanent connection of generations has inspired the world civilizations to create rules of succession for establishing people’s obedience to them. In the old times, the transmission of property of the Romanian people was governed by the legislation, which had been created under the influence of the Roman law. According to the conception of this legislation, a deceased person’s property had to stay with his blood relatives i.e. within the same family. On the background of these circumstances, a surviving spouse suffered disadvantages. A widow’s rights were limited in accordance with the old Georgian legislation too – the hereditary property was mainly divided between the male issue, while females owned only wedding gifts (dowry. However, the area of family law has suffered crucial changes throughout the centuries. Nowadays, during the times of globalization, these changes are directed towards the internationalization of legal systems of the world. Juridical differences are becoming irrelevant and females’ rights are equalized with the males’ ones. The given paper is dedicated to the precise study of the Romanian and Georgian “testate successions”. It singles out major terminological units and discusses women’s rights vis-à-vis men’s ones.

    Full Text Available BACKGROUND: Tuberculosis is a major occupational hazard in low and middle-income countries. Limited data exist on serial testing of healthcare workers (HCWs with interferon-γ release assays (IGRAs for latent tuberculosis infection (LTBI, especially in low and middle-income countries. We sought to evaluate the rates of and risk factors for LTBI prevalence and LTBI test conversion among HCWs using the tuberculin skin test (TST and QuantiFERON-TB Gold In-tube assay (QFT-GIT. METHODS: A prospective longitudinal study was conducted among HCWs in the country of Georgia. Subjects completed a questionnaire, and TST and QFT-GIT tests were performed. LTBI testing was repeated 6-26 months after baseline testing. RESULTS: Among 319 HCWs enrolled, 89% reported prior BCG vaccination, and 60% worked in TB healthcare facilities (HCFs. HCWs from TB HCFs had higher prevalence of positive QFT-GIT and TST than those from non-TB HCFs: 107/194 (55% vs. 30/125 (31% QFT-GIT positive (p<0.0001 and 128/189 (69% vs. 64/119 (54% TST positive (p = 0.01. There was fair agreement between TST and QFT-GIT (kappa = 0.42, 95% CI 0.31-0.52. In multivariate analysis, frequent contact with TB patients was associated with increased risk of positive QFT-GIT (aOR 3.04, 95% CI 1.79-5.14 but not positive TST. Increasing age was associated with increased risk of positive QFT-GIT (aOR 1.05, 95% CI 1.01-1.09 and TST (aOR 1.05, 95% CI 1.01-1.10. High rates of HCW conversion were seen: the QFT-GIT conversion rate was 22.8/100 person-years, and TST conversion rate was 17.1/100 person-years. In multivariate analysis, female HCWs had decreased risk of TST conversion (aOR 0.05, 95% CI 0.01-0.43, and older HCWs had increased risk of QFT-GIT conversion (aOR 1.07 per year, 95% CI 1.01-1.13. CONCLUSION: LTBI prevalence and LTBI test conversion rates were high among Georgian HCWs, especially among those working at TB HCFs. These data highlight the need for increased implementation of TB

    Full Text Available One of the part of the Black Sea Nowcasting/Forecasting System is the regional forecasting system for the Easternmost part of the Black Sea (including the Georgian water area, which have been developed within the context of the EU International projects ARENA and ECOOP. A core of the regional system is a high-resolution baroclinic regional model of the Black Sea dynamics developed at M. Nodia Institute of Geophysics (RM-IG. This model is nested in the basin-scale model (BSM of Marine Hydrophysical Institute (MHI, Sevastopol/Ukraine. The regional area is limited to the Caucasian and Turkish coastal lines and the western liquid boundary coinciding with a meridian 39.36° E. Since June 2010 we regularly compute 3 days' forecasts of current, temperature and salinity for the Easternmost part of the Black Sea with 1 km spacing. In this study results of two forecasts are presented. The first forecast corresponds to Summer season and covers the prognostic interval from 00:00 h, 6 August to 00:00 h, 9 August 2010. The second one corresponds to Autumn season and covers the prognostic interval from 00:00 h, 26 October to 00:00 h, 29 October 2010. Data needed for the forecasts – the 3-D initial and prognostic hydrophysical fields, also 2-D prognostic meteorological fields at the sea surface, wind stress, heat fluxes, evaporation and precipitation rates for the our regional area are placing on the MHI server every day and we are available to use these data operatively. Prognostic hydrophysical fields are results of forecast by BSM of MHI and 2-D meteorological boundary fields represent results of forecast by regional atmospheric model ALADIN. All these fields are given on the grid of BSM with 5 km spacing and with one-hour time step frequency for the integration period. The analysis of predicted fields shows that to use the model with high resolution is very important factor for identification of nearshore eddies of small sizes. It should be noted very

    Epidemiological studies in high income countries suggested that a big proportion of the population in Europe and America report adverse reactions to food. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. The aim of our study was to report the prevalence of self-reported food allergy in the different age groups of Georgian population and to reveal the most common self-reported food allergens. ISAAC phase III study methodology and questionnaires were used for data collection. Questions about food allergy were added to the survey and involved questions about self-reported food allergy. 6-7 years old 6140 children (response rate-94,5%) and 13-14 years old 5373 adolescents (response rate-86,9%) from two locations of Georgia, Tbilisi and Kutaisi were surveyed. 500 randomly assessed adults from Tbilisi aged 18 years and older were added later (response rate-97,6%). Findings revealed that self-reported food allergy among 6-7 years old age group and 13-14 years old age were almost the same (15,7% and 15,9% correspondingly) and slightly lower in adult population - 13,9%. Study revealed, that hen's egg was the commonest implicated food for 6-7 years age group, hazel nut - for 13-14 years old age group followed by hen's egg. Walnut and hazel nut were most reported foods for adult population. The findings also revealed that food allergy is one of the most important risk factor for symptoms associated with asthma (OR-3,05; 95%CI 2.50-3.74), rhinoconjunctivitis (OR-2,85; 95%CI 2.24-3.64) and eczema (OR-5,42; 95%CI 4.08-7.18) in childhood. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

    Full Text Available In Georgia, one of the most ancient vine-growing environment, the homemade production of wine is still very popular in every rural family and spontaneous fermentation of must, without addition of chemical preservatives, is the norm. The present work investigated the yeast biodiversity in five Georgian areas (Guria, Imereti, Kakheti, Kartli, Ratcha-Lechkhumi sampling grapes and wines from 22 different native cultivars, in 26 vineyards and 19 family cellars. One hundred and eighty-two isolates were ascribed to 15 different species by PCR-ITS and RFLP, and partial sequencing of D1/D2 domain 26S rDNA gene. Metschnikowia pulcherrima (F’ = 0.56, I’ = 0.32, Hanseniaspora gulliermondii (F’ = 0.49, I’ = 0.27 and Cryptococcus flavescens (F’ = 0.31, I’ = 0.11 were the dominant yeasts found on grapes, whereas Saccharomyces cerevisiae showed the highest prevalence into wine samples. Seventy four isolates with fermentative potential were screened for oenological traits such as ethanol production, resistance to SO2, and acetic acid, glycerol and H2S production. Three yeast strains (Kluyveromyces marxianus UMY207, S. cerevisiae UMY255, Torulaspora delbrueckii UMY196 were selected and separately inoculated in vinifications experiments at a Georgian cellar. Musts were prepared from healthy grapes of local varieties, Goruli Mtsvane (white berry cultivar and Saperavi (black berry cultivar. Physical (°Brix and microbial analyses (plate counts were performed to monitor the fermentative process. The isolation of indigenous S. cerevisiae yeasts beyond the inoculated strains indicated that a co-presence occurred during the vinification tests. Results from quantitative GC-FID analysis of volatile compounds revealed that the highest amount of fermentation flavours, such as 4-ethoxy-4-oxobutanoic acid (monoethyl succinate, 2-methylpropan-1-ol, ethyl 2-hydroxypropanoate and 2-phenylethanol, were significantly more produced in fermentation conducted in Saperavi

    The first electric projecting microscope and the first published photomicrographs harnessed recent technological developments to provide improved methods of medical illustration for educational purposes. Both projects were the work of two Frenchmen. The impetus came from the microscopist Dr Alfred Donné (1801-78), discoverer of trichomonas vaginalis and leukaemia. Implementation was primarily by his medical-student assistant, Léon Foucault (1819-68), who later gained fame as a physicist, especially with his pendulum demonstration of the Earth's rotation.

    Benjamin Franklin had at least two accidents that resulted in electricity passing through his brain. In addition, he witnessed a patient's similar accident and performed an experiment that showed how humans could endure shocks to the head without serious ill effects, other than amnesia. Jan Ingenhousz, Franklin's Dutch-born medical correspondent better known for his discovery of photosynthesis, also had a serious accident that sent electricity though his head and, in a letter to Franklin, he described how he felt unusually elated the next day. During the 1780s, Franklin and Ingenhousz encouraged leading French and English electrical "operators" to try shocking the heads of melancholic and other deranged patients in their wards. Although they did not state that they were responding to Ingenhousz's and Franklin's suggestions, Birch, Aldini, and Gale soon did precisely what Ingenhousz and Franklin had suggested. These practitioners did not appear to induce convulsions in their mentally ill patients, but they still reported notable successes.

    The main purpose of the European School Survey Project on Alcohol and Other Drugs (ESPAD) is to collect comparable data on substance use among 15-16 year-old European students in order to monitor trends within as well as between countries. In the article the results of the pilot study of Alcohol Use among Georgian Students, rigorously following Criteria of European School Project on Alcohol and Other Drug (ESPAD) are presented. The survey was conducted according to a standardized methodology and with a standardized questionnaire. Data were collected during February 2009 and the target population was Tbilisi students in the 10-th grade (93% born in 1992), with a mean age of 16.1 years at the time of data collection. Data were collected by group-administered questionnaires. The students answered the questionnaires anonymously in the classroom with researchers. The survey revealed that alcoholic beverages, especially beer and wine are considered easily available; 73% found beer and 70% wine easy to obtain. 90% of the surveyed students have tried alcohol at least once during their lifetime. 80% have done so in the last 12months and 40% in the past 30 days. Gender differences become apparent when frequency of use is considered: boys have used alcohol more often than girls. 7.5% of the students state that, they never drink alcohol at all. Wine and beer are the two most important types of beverage for the students. On average, 40% of students on the latest drinking day consumed wine and 38% - beer. Champagne and spirits consumed 29% and 22% of students, respectively. On average, half of the students have been intoxicated, at least once during their lifetime, to the point of staggering when walking, having slurred speech or throwing up. 40% reported intoxication in the last 12 months and 12% in the past 30 days. Another way to measure drunkenness is to ask about a specific amount of alcohol consumed within a certain period of time. The students were asked if they had had

    The main purpose of the European School Survey Project on Alcohol and Other Drugs (ESPAD) is to collect comparable data on substance use among 15-16 year-old European students in order to monitor trends within as well as between countries. This summary presents key results from the Tobacco Use in Georgian Students, pilot study rigorously following Criteria of European School Project on Alcohol and Other Drug (ESPAD). The survey was conducted according to a standardized methodology and with a standardized questionnaire. Data were collected during February 2009 and the target population was Tbilisi students in the 10-th grade (93% born in 1992), with a mean age of 16.1 years at the time of data collection. Data were collected by group-administered questionnaires. The students answered the questionnaires anonymously in the classroom with researchers. On average, in our survey, about half of the surveyed students reported having tried smoking cigarettes at least once and 16% had used cigarettes during the past 30 days. 1.1% of all students had smoked at least a packet of cigarettes per day during the last 30 days. On average 60% of surveyed students replied that they find it fairly or very easy to get cigarettes if they want to. On average, 30% (10% - 9 years old or less) of the students said that they had been smoking cigarettes on a daily basis at the age of 13 or younger. The proportion of students who smoked on a daily basis at the age of 13 or younger is 4.3%. Adolescent's tobacco use is a great public health concern in Georgia. Smoking is quite prevalent among Georgian adult population which on one hand reflects their children's habits and on the other hand reflects not only their, but their families and broader community's health. The consumption level among adults and their attitudes towards the substance in question can be one factor that affects use among teenagers. So may the magnitude of information and preventive efforts. Availability, not only in physical

    Nosocomial infections still remain a serious problem in patients undergoing open heart surgery. The aim of the study was to determine the incidence, etiology and main risk factors of nosocomial infections (NI) following cardiac surgery in congenital heart diseases population. Retrospective case study was conducted. 387 patients with congenital heart disease (CHD), who underwent cardiac surgery from January 2007 to December 2008 were studied. The age of the most patients varied between 1 day to 15 years, 73 patients (18,8%) were older than 15 years. All 387 patients underwent cardiac surgery. The rate of NI was 16%. The most common infections were bloodstream infections (BSI) (7,75%) and respiratory tract infections (7%) respectively. The rate of NI was higher in patients under 1 year of age, after urgent surgery and urgent reoperation, long cardiopulmonary bypass (CPB) and aortic cross-clamp time, also in patients with prolonged mechanical ventilation, massive haemotransfusion, with open heart bone after surgery, reintubation, hospitalization in another hospital during last three month. It was concluded that the most common nosocomial infection after cardiac surgery congenital heart diseases in Georgian population was blood stream infection. The main risk factors of NI in the same setting were age under 1 year, urgent surgery, urgent reoperation, long CPB and aortic cross-clamp time, long duration of mechanical ventilation, massive haemotransfusion, open heart bone after surgery, reintubation, hospitalization in another hospital during last three month.

    Full Text Available This chapter analyses the historical background to the secessionist conflict in Abkhazia and the prospect of a settlement. The Georgian-Abkhaz conflict, driven by a need for identity and security, is one that failed to be resolved within the hierarchical federal framework of the Soviet state. Abkhazia seceded from Georgia as a result of the 1992-93 war. UN mediation has so far failed to bring a political settlement closer. The chapter describes the solutions proposed and political actions taken both by the parties to the conflict and by the external mediators. It assesses the way in which the conflicting parties perceive the process of Europeanization in their region, the role of the European Union in the conflict on Abkhazia, and possible future outcomes. The UN proposals for a settlement make it possible to envisage the future of Abkhazia either as part of a federation with Georgia or as an associated state with Georgia, but as long as the external powers are unable to devise a common approach to overcoming the present deadlock in the political negotiations, it remains difficult to predict the precise outcome of the conflict.

    A 75-year-old female complained of severe chest pain and was emergently admitted to our hospital because of anterior acute myocardial infarction. Emergent coronary angiography was performed and revealed occlusion in segment 7, so a stent was implanted. Lidocaine, carvedilol, amiodarone, magnesium, and nifekalant were administered successively because non-sustained ventricular tachycardia (NSVT) frequently appeared like an electrical storm. After nifekalant administration, QTc was significantly prolonged and torsades de pointes was induced. Overdrive pacing was performed and finally the NSVT was completely controlled. If fatal arrhythmias such as NSVT show resistance to medication, overdrive pacing should be considered to stabilize the arrhythmia associated with acute coronary syndrome.

    Hermetic electrical feedthroughs are essential for safe and functional active implantable biomedical devices and for a wide range of other applications such as batteries, supercapacitors, OLEDs and solar cells. Ceramics and metals have previously been the materials of choice for encapsulations, while polymers have advantages of ease of mass production and end user compatibility. We demonstrate a laser sealing technology that gives hermetic, mechanically strong feedthroughs with low electrical resistance in a polyetheretherketone (PEEK) encapsulation. The conductive pathways are wires and sputtered thin films. The water vapor transmission rate through the fabricated encapsulations is comparable to that of PEEK itself.

    Medical guidelines are presented by which the physician may evaluate a patient for participation in a program of active physical therapy (A.P.T.). A.P.T. system modalities are introduced and defined as: a) isokinetic leg trainer, b) stationary bicycle ergometer, c) outdoor exercise bicycle, and d) Functional Electrical Stimulation (F.E.S.)--Orthosis for ambulation. The physiological responses to these F.E.S. exercise modalities are reviewed. Initial and interim patient evaluations are discussed. The initial patient evaluation includes a history, physical examination, lab tests, and a report summary, all of which culminate in an F.E.S. exercise prescription. The interim patient evaluation is performed for continuation-termination purposes as well as to progress the patient through the various F.E.S. exercise modalities. Specific F.E.S. exercise progression criteria are summarized. The medical criteria are presented with respect to both patient participation in the F.E.S. exercise program and patient monitoring during the exercise itself. Specific medical criteria for patient participation in A.P.T. are organized around eight functional categories: a) level of neurological injury, b) muscular system, c) skeletal system, subdivided into bone criteria and joint criteria, d) cardiovascular system, e) respiratory system, f) urogenital system, g) cutaneous system, and h) psychological system. The medical criteria for patient monitoring during F.E.S. exercise are discussed with respect to: a) cardiovascular monitoring, b) objective patient monitoring, and c) F.E.S. exercise system monitoring. The article concludes with a discussion of informed consent when applied to an emerging treatment modality.

    The ability of the Lorentz force to link a mechanical displacement to an electrical current presents a strong interest for medical acoustics, and three applications were studied in this thesis. In the first part of this work, a hydrophone was developed for mapping the particle velocity of an acoustic field. This hydrophone was constructed using a thin copper wire and an external magnetic field. A model was elaborated to determine the relationship between the acoustic pressure and the measured electrical current, which is induced by Lorentz force when the wire vibrates in the acoustic field of an ultrasound transducer. The built prototype was characterized and its spatial resolution, frequency response, sensitivity, robustness and directivity response were investigated. An imaging method called Lorentz Force Electrical Impedance Tomography was also studied. In this method, a biological tissue is vibrated by ultrasound in a magnetic field, which induces an electrical current by Lorentz force. The electrical imp...

    Incomplete and superficial knowledge of morphological types and anatomical variations of the root canal system will become the reason leading to the failure of endodontic treatment. cone-beam computed tomography (CBCT) - it is a technologically more sophisticated, interesting, reliable, non-invasive imaging technique with high degree of visualization, considered as a particularly important and useful tool to study complexity and variability of canal system. 2753 teeth of 228 patients have been studied by CT. Ages of the patients varied within 25-55 years. Among them 122 men and 106 women. Maxillary teeth - 1394 and mandibular - 1359, respectively. The aim of our study was investigation and evaluation of: tooth length, number of roots and canals, type of configuration, root canal curvature and degree of curvature in Georgian population. The results of the study revealed interesting data and anatomical characteristics, those replicating the racial signs and differs from the data recorded by the other researchers, became evident. In studying of dental form variations were interested anatomists (description and comparison) anthropologists, biologists, palaeontologists and stomatologists. The field of human dental anatomy has not been completely explored so, the modern human teeth still remain a matter of continual curiosity and research. The knowledge of anatomical characteristics of dental root canals will help clinicians to optimize the algorithm of endodontic treatment. Thus, statistic data are not the universal criterias, however, basing on these indicators anthropometrical data of roots and canals vary according to the geographic zones and nationalities. The study of variations in tooth form has interested anatomists (description and comparison), anthropologists, biologists, palaeontologists and dentists. The field of human dental anatomy has not been completely explored and the dentition of modern man still remains a matter of continual curiosity and research

    The main purpose of the European School Survey Project on Alcohol and Other Drugs (ESPAD) is to collect comparable data on substance use among 15-16 year-old European students in order to monitor trends within as well as between countries. This summary presents key results from the Alcohol Use in Georgian Students, pilot study rigorously following Criteria of European School Project on Alcohol and Other Drug (ESPAD). The survey was conducted according to a standardized methodology and with a standardized questionnaire. Data were collected during February 2009 and the target population was Tbilisi students in the 10-th grade (93% born in 1992), with a mean age of 16.1 years at the time of data collection. Data were collected by group-administered questionnaires. The students answered the questionnaires anonymously in the classroom with researchers. 22% of the surveyed students perceive cannabis to be easily available, and boys consider cannabis slightly more accessible than girls do, the gender difference is rather big (31% vs.13%). Amphetamines and ecstasy are not perceived to be as easily available as cannabis. On average, 33% of the boys and 8% of the girls have tried illicit drugs at least once during their lifetime (20% for all students). After cannabis, ecstasy is in second position, being mentioned by 7.5% of the students and the figure for amphetamines is about 2%. Lifetime use of crack was reported by fewer students (1.1%) and the rate for heroin was even lower (1%). Lifetime cocaine and heroine experiences were reported by 0.6% of the students on average. Just as few reported experience of GHB and anabolic steroids or drug use by intravenous administration. Since cannabis is the most frequently used illicit drug, it could be worthwhile to have a closer look at this substance. Use of cannabis in the past 12 months was reported by 17% of the boys and 3% of the girls (10% for all students) while use in the past 30 days was stated by 6.5% of the boys and 0

    The development of needle materials to be used for stimulating electrotherapy was studied. The aimed material was plastic which is low cost and flexible, and has uniform electric conductivity. Polypropylene as the material and carbon such as graphite as the electric conductive filler were selected. It was found that the increase of filler addition lowered the variation of electric resistance but lost flexibility. Carbon of super fine particles as the filler was studied to get the aimed skin resistance value with a small amount of addition, and this aim could be achieved by adding 10 to 20 PHR of carbon black of 30[mu]m average diameter. The addition of 3PHR was determined as the optimal mixing condition by determining the relationship between the dispersant (like oleic acid, etc.) and the electric conductivity and from the relationship between the original torque value and the variation of electric conductivity. It was clarified that the temperature relates to filler dispersion by studying the relationship between the mixing temperature and the electric conductivity. It was confirmed that when raw materials are irradiated by electricity, static electricity generated at mixing from resin is suppressed and filler aggregation can be prevented. 5 figs., 6 tabs.

    Duration of treatment of venous thromboembolism (VTE) and prevention of its recurrence represent significant problems of contemporary medicine, as the basic method of treatment - anticoagulation is frequently complicated by hemorrhage. Therefore, its duration is strictly defined and depends on existence of risk factors related to recurrence of thrombosis. Purpose of the conducted study was to establish the role of point mutations of prothrombin (PHG) - 20210G/A; Factor V Leiden (FVL) - 1691G/A and methylenetetrahydrofolate reductase (MTHFR) - 677C/T genes, i.e. inherited thrombophilia in the pathogenesis of proximal and distal lower extremity deep vein thrombosis in patients of the Georgian population, as in case of proximal thrombosis there is a higher risk of recurrent thrombosis. The above mutations were detected by PCR and single nucleotide primer extension reaction, followed by Enzyme Linked Immuno-Sorbent Assay (ELISA) in 61 patients with venous thromboembolism of various localizations, out of which: 49 patients were diagnosed with unprovoked proximal thromboembolism confirmed by objective studies and 12 patients were diagnosed with distal thromboembolism. The difference between the groups was evaluated by F (Fisher) precise criterion. According to statistical analysis of the results, incidence of FVL mutation in the group of patients with proximal thrombosis was significantly higher compared to patients with distal thrombosis 0.43 and 0.08 (p=0.0256), respectively. Similar tendencies were observed in case of carriage of prothrombin gene and MTHFR gene mutations, as their presence was higher in the group of patients having proximal thrombosis than in patients with distal thrombosis, however, this difference was not found to be statistically significant. It should be particularly mentioned that double or triple heterozygous or homozygous carriage of studied mutations with various options was confirmed in 15 of 61 patients and the above genotypes were observed

    Previous research has documented the importance of parenting on adolescent health and well-being; however, some of the underlying mechanisms that link the quality of parent-child relationship to health, adjustment, and well-being are not clearly understood. The current study seeks to address this gap by examining the extent to which sleep functioning mediates the effects by parental warmth on different measures of adolescent problem behaviors. Specifically, we test whether sleep functioning, operationalized by sleep quality and sleep quantity, mediates the relationship between the parental warmth and three measures of problem behaviors, namely alcohol use, illegal drug use, and deviance, in two nationally representative samples of Georgian (N = 6,992; M = 15.83, 60% females, and Swiss (N = 5,575; M = 17.17, 50% females) adolescents. Based on tests for parallel mediating effects by sleep functioning of parental warmth on problem behaviors in the MEDIATE macro in SPSS, the findings provided evidence that both sleep quality and sleep quantity independently and cumulatively mediated the effects of parental warmth on each of the three problem behaviors in both samples, with one exception. These results highlight the salience of positive parenting on sleep functioning among teens in two different cultural contexts, and, in turn, on measures of problem behaviors.

    Georgia, in the Caucasian region, is considered the first domestication centre of grapevine. This country is characterized by high morphological variability of cultivated (Vitis vinifera L. subsp. sativa (DC.) Hegi) and wild (Vitis vinifera L. subsp. sylvestris (Gmel.) Hegi) compartments. The main objective of this study was to investigate the level of genetic diversity obtained by the novel custom Vitis18kSNP array, in order to analyse 71 grapevine accessions representative of wild and cultivated Georgian germplasms. The number of loci successfully amplified was 15,317 out of 18,775 SNP and 79 % of loci resulted polymorphic. Sixty-eight unique profiles were identified, 42 for the sativa and 26 for the sylvestris compartment. Cluster analysis highlighted two main groups, one for cultivars and another for wild individuals, while a genetic structure according to accession taxonomic status and cultivar geographical origin was revealed by multivariate analysis, differentiating clearly the genotypes into 3 main groups, two groups including cultivars and one for wild individuals, even though a considerable overlapping area was observed. Pattern of genetic diversity structure presented an additional proof that grapevine domestication events took place in the Caucasian region contributing to the crop evolution. Our results demonstrated a moderate differentiation between sativa and sylvestris compartments, even though a connection between several samples of both subspecies may be assumed for the occurrence of cross hybridization events among native wild populations and the cultivated accessions. Nevertheless, first degree relationships have not been discovered between wild and cultivated individuals.

    Due to recent population aging, the number of check-up for senior citizens has increased steadily. According to this trend, the market size of dental X-ray equipment and the number of approval and review for these devices have simultaneously increased. The technical document of medical device is required for approval and review for medical device, and medical device companies needs to have work comprehension and expertise, as the document needs to include the overall contents such as performances, test criteria, etc.. Yet, since most of domestic manufacturers or importers of medical devices are small businesses, it is difficult for them to recruit professional manpower for approval of medical devices, and submission of inaccurate technical documents has increased. These problems lead to delay of the approval process and to difficulties in quick entering into the market. Especially, the Ministry of Food and Drug safety (MFDS) standards of a dental extra-oral X-ray equipment, a dental intra-oral X-ray equipment, an arm-type computed tomography, and a portable X-ray system have been recently enacted or not. this guideline of dental X-ray equipment adjusting revised standards was developed to help relative companies and reviewers. For this study, first, the methods to write technical document have been reviewed with revised international and domestic regulations and system. Second, the domestic and foreign market status of each item has been surveyed and analyzed. Third, the contents of technical documents already approved by MFDS have been analyzed to select the correct example, test items, criteria, and methods. Finally, the guideline has been developed based on international and domestic regulation, through close review of a consultative body composed of academic, industrial, research institute and government experts.

    Full Text Available According to the Ministry of Labor, Health and Social Affairs of Georgia a new health management system has to be introduced in the nearest future. In this context arises the problem of structuring and classifying documents containing all the history of medical services provided. The present work introduces the instrument for classification of medical records based on the Georgian language. It is the first attempt of such classification of the Georgian language based medical records. On the whole 24.855 examination records have been studied. The documents were classified into three main groups (ultrasonography, endoscopy, and X-ray and 13 subgroups using two well-known methods: Support Vector Machine (SVM and K-Nearest Neighbor (KNN. The results obtained demonstrated that both machine learning methods performed successfully, with a little supremacy of SVM. In the process of classification a “shrink” method, based on features selection, was introduced and applied. At the first stage of classification the results of the “shrink” case were better; however, on the second stage of classification into subclasses 23% of all documents could not be linked to only one definite individual subclass (liver or binary system due to common features characterizing these subclasses. The overall results of the study were successful.

    This descriptive study examined characteristics of older Georgians receiving Older Americans Act Nutrition Program Services and other home- and community-based services (HCBS) using state aging administrative data (N = 31,341, mean age: 76.6 ± 9.2 y, 71.2% female, 52.3% White). Home-delivered meals (HDM) was used most frequently. The characteristics of older Georgian HCBS participants varied by the type and number of HCBS received. Those receiving HDM and other in-home and caregiving services were more likely to show poorer sociodemographic, economic, and functional characteristics, and food insecurity. Those receiving multiple HCBS were most vulnerable, but showed lower level of food insecurity than those receiving single HCBS, suggesting potential combined benefits of receiving multiple programs. This study underscores the importance of documenting dynamic needs for HCBS, especially HDM, among vulnerable older adults as part of standard administrative process to identify those at high risk of institutionalization, optimize HCBS delivery and coordination, and maximize HCBS benefits.

    The market size of the bone absorptiometric X-ray system and the number of its approval by Ministry of Food and Drug Safety (MFDS) has annually increased, with a trend of increasing aging population and osteoporosis patients. For approval of manufactured or imported medical devices in Republic of Korea, it is required to submit its technical document. Therefore, it is need to develop the technical document guideline for the bone absorptiometric X-ray system for manufacturers, importers and reviewers. First of all, the technical documents which were already approved were examined and analyzed through MFDS approval administration system. Second, safety and performance test standards and methods that match international standards were drawn after conducting survey of the market status and the technology development trend for it, with examination and analysis of applicable domestic and overseas standards. Third, by operating industry-research-government cooperation, the guideline draft on writing technical document for the bone absorptiometric X-ray system was discussed, collecting their opinion. As a result, it is suitable to international and domestic condition, includes test evaluation methods and offer various information with appropriate examples to civil petitioner, when they write the technical documents.

    Full Text Available Background: Cerebral palsy is the leading cause of physical disability in pediatric  age. The search for new methods and improvement of old rehabil- itation techniques is ongoing, due to low efficacy of the latter. Aim: To assess the efficacy of a func- tional programmed electrical muscle stimulation as a part  of combination treatment of patients with cerebral palsy in the form of spastic diplegia. Materials and methods: We analyzed the results of treatment of 71 children with cerebral palsy and spastic diplegia, who had  been  randomized  into two groups  depending on the type of treatment. In  the  first group,  the  patients  (n = 38 received a course of functional programmed electric stim- ulation  in combination with  other  non-medical treatment  methods.  The  second   group   (n = 33 underwent a usual  course  of electrical  stimula- tion in combination with non-medical  treatment, similar to that  in the first group. The third group (control   included   41   children   without    cere- bral palsy. Clinical and  instrumental parameters were  assessed  in all study  participants. Results: After the course of combination treatment in the group  1, the  tonus  of m. gastrocnemius was de- creased significantly by 41%, that of the posterior group  of femur muscles by 43%, adductor group of femur muscles by 36%. In the group  2, the re- spective parameters decreased by 24, 21 and 21%. Muscle power  endurance was  increased  signifi- cantly in patients of both groups: that of long back extensors by 12.5 and 6.2 sec, of m. rectus abdomi- nis by 10.6 sec and 5.2 sec, of gluteal muscles by 9.3 and 4.6 sec, of m. quadriceps  by 19.8 and 7.2 sec, of m. anterior  tibialis by 12.1 and 4.6 sec, respec- tively.

    Students in developing countries interested in STEM disciplines (science, technology, engineering & math) often choose majors that will improve their job opportunities in their home country when they graduate, e.g. engineering or medicine. Geoscience might be chosen as a sub-discipline of civil engineering, but rarely as a primary major unless there are local economic natural resources. The Institute of International Education administers the ExxonMobil Middle East and North Africa region scholars program designed to develop skilled students with a focus on geoscience and to build relationships with academic leaders by offering select faculty the opportunity to participation in the AGU fall meeting. At the Jordan University of Science and Technology (JUST), research in electrical engineering applied to medicine has potential links to geosciences. In geophysics, neural wavelet analysis (NWA) is commonly used to process complex seismic signals, e.g. for interpreting lithology or identifying hydrocarbons. In this study, NWA was used to characterize cardiac arrhythmias. A classification scheme was developed in which a neural network is used to identify three types of arrhythmia by distinct frequency bands. The performance of this scheme was tested using patient records from two electrocardiography (ECG) databases. These records contain normal ECG signals, as well as abnormal signals from atrial fibrillation (AF), ventricular tachycardia (VT) and ventricular fibrillation (VF) arrhythmias. The continuous wavelet transform is applied over frequencies of 0-50 Hz for times of 0-2s. For a normal ECG, the results show that the strongest signal is in a frequency range of 4-10 Hz. For AF, a low frequency ECG signal in the range of 0-5 Hz extends over the whole time domain. For VT, the low frequency spectrum is in the range of 2-10 Hz, appearing as three distinct bands. For VF, a continuous band in the range of 2-10 Hz extends over the whole time domain. The classification of

    2017-01-01

    Full Text Available Nowadays enterprises should consider seeking to reduce the supply chain risks as a crucial part of their activities in order to improve their competitiveness in the international context. Choosing the suitable strategy in connection with assigning some parts of the production process to outside the organization is a complex multi-criteria decision making problem and it gets more complicated when supply chain risk factors as the factors to select the strategy as well as dependence and the close ties between these criteria also be considered. In this paper, after the identification of risks in the supply chain of a medical equipment manufacturer company, dependence and ties between criteria in line with choosing the best strategy among existing alternatives has been examined in the form of a combined ANP-ELECTRE method. This combined model is of high performance to give a solution to the problem considered in this paper. But given the complex and time consuming nature of the AHP and ELECTRE, in this study a meta-heuristic algorithm is developed called SIMANP that despite the simplicity of computing and high-speed, is good in the terms of precision and efficiency. The results of comparing SIMANP algorithm and the proposed ANP - ELECTRE method are presented at the end.

    2015-12-01

    Full Text Available The gradual MS 7021 (kept at Poznań University Library is one of the earliest examples of the reception of post-Trent reform of Gregorian plainchant in the seventeenth century Poland. The volume comes from the scriptorium of Benedictine convent in the Chełmno congregation. The article’s aim is to present the liturgical alterations and changes that occurred in the Polish Republic in the early seventeenth century with the example provided by an analysis of the content of the Benedictine manuscript as well as other available sources. Additionally, the article examines the problem of the reform of the Georgian repertoire introduced by the Apostolic See and the its subsequent reception in Poland. In the liturgy of the Western World, the most significant outcome of the post- Trent reform was the introduction of standarised principal liturgical books, which in consequence led to a unification of liturgy in the whole of the Church’s life. The Polish–Lithuanian Commonwealth adopted the breviary and the Roman Missal, the liturgical book that contains the texts and rubrics for the celebration of the Mass in the Roman Rite of the Catholic Church, as well as the antiphonary and gradual. Local traditions, however, were attempted to be retained in these liturgical books, so that the proper Roman rite could not have been implemented to the full. However, the gradual, MS 7021 BU UAM, from the Toruń scriptorium of the Benedictine convent, is an example of the implementation the Trent reform in the seventeenth century Polish-Lithuanian Commonwealth that has no connections with any local or locallybased monastic tradition. The Benedictine nuns from the Chełmno congregation were undoubtedly prominent in the history of the Trent reform in the Republic of Both Nations. By dissenting from the spirit of St. Benedict’s rule professed by the Tyniec Benedictines, and by creating their own rule based on the resolutions of the Council of Trent, the convent

    Technologic innovations enable management of medical equipment and power supply systems, with improvements that can affect the technical aspects, economics, and quality of medical service. Herein are outlined some technical guidelines, proposed by Istituto Superiore per la Prevenzione e la Sicurezza del Lavoro, for increasing the effectiveness of the power supply system and the safety of patients and surgeons in the operating room, with particular focus on transplantation. The dependence of diagnoses and therapies on operation of the electrical equipment can potentially cause great risk to patients. Moreover, it is possible that faulty electrical equipment could produce current that may flow through the patient. Because patients are particularly vulnerable when their natural protection is considerably decreased, as during transplantation or other surgery, power supply systems must operate with a high degree of reliability and quality to prevent risk, and must be designed to reduce hazards from direct and indirect contact. Reliability of the power supply system is closely related to the quality of the project, choice of materials, and management of the system (eg, quality and frequency of servicing). Among the proposed guidelines, other than normal referencing, are (1) adoption of a monitoring system to improve the quality of the electrical parameters in the operating room, (2) institution of emergency procedures for management of electrical faults, (3) a procedure for management of fires in the operating room, (4) and maintenance interventions and inspections of medical devices to maintain minimal requirements of safety and performance.

    Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. These concepts are discussed.

    Amaryllidaceae alkaloids exhibit antitumour, antiviral and anticholinergic activities. Some of them have been used in the treatment of myasthenia gravis, myopathy and diseases of the nervous system. In this study, the characterization of these compounds from Amaryllidaceae plants along with some biological activities and some regulations to conserve the native flora will be reviewed. Plants materials: Galanthus shaoricus Kem.-Nath., were collected in 2007-2008 during the flowering period in Georgia. The preparation of extracts and fractions were obtained using methanolic maceration. Crude alkaloidal extracts were typically purified by liquid-liquid partitioning of their basic forms in chloroform. Lycorine, galantamine and tazettine has been found as one of the major alkaloid from Amaryllidaceae plants. Galanthus shaoricus have shown good antimalarial and cytotoxic activity in a dose-dependent manner.

  11. Electrically Conductive Anodized Aluminum Surfaces

    Science.gov (United States)

    Nguyen, Trung Hung

    2006-01-01

    Anodized aluminum components can be treated to make them sufficiently electrically conductive to suppress discharges of static electricity. The treatment was conceived as a means of preventing static electric discharges on exterior satin-anodized aluminum (SAA) surfaces of spacecraft without adversely affecting the thermal-control/optical properties of the SAA and without need to apply electrically conductive paints, which eventually peel off in the harsh environment of outer space. The treatment can also be used to impart electrical conductivity to anodized housings of computers, medical electronic instruments, telephoneexchange equipment, and other terrestrial electronic equipment vulnerable to electrostatic discharge. The electrical resistivity of a typical anodized aluminum surface layer lies between 10(exp 11) and 10(exp 13) Omega-cm. To suppress electrostatic discharge, it is necessary to reduce the electrical resistivity significantly - preferably to anodized surface becomes covered and the pores in the surface filled with a transparent, electrically conductive metal oxide nanocomposite. Filling the pores with the nanocomposite reduces the transverse electrical resistivity and, in the original intended outer-space application, the exterior covering portion of the nanocomposite would afford the requisite electrical contact with the outer-space plasma. The electrical resistivity of the nanocomposite can be tailored to a value between 10(exp 7) and 10(exp 12) Omega-cm. Unlike electrically conductive paint, the nanocomposite becomes an integral part of the anodized aluminum substrate, without need for adhesive bonding material and without risk of subsequent peeling. The electrodeposition process is compatible with commercial anodizing production lines. At present, the electronics industry uses expensive, exotic, electrostaticdischarge- suppressing finishes: examples include silver impregnated anodized, black electroless nickel, black chrome, and black copper.

    Full Text Available A major problem facing battery-powered electric vehicles is in their batteries: weight and charge capacity. Thus, a battery-powered electric vehicle only has a short driving range. To travel for a longer distance, the batteries are required to be recharged frequently. In this paper, we construct a model for a battery-powered electric vehicle, in which driving strategy is to be obtained such that the total travelling time between two locations is minimized. The problem is formulated as an optimization problem with switching times and speed as decision variables. This is an unconventional optimization problem. However, by using the control parametrization enhancing technique (CPET, it is shown that this unconventional optimization is equivalent to a conventional optimal parameter selection problem. Numerical examples are solved using the proposed method.

Patients are increasingly seeking a variety of medical treatments abroad, particularly those involving cosmetic surgery and dental treatment, often in countries in South-East Asia. Adverse events may occur during medical treatment abroad, which raises medico-legal and insurance issues, as well as concerns regarding follow-up of patients. General practitioners need to be prepared to offer advice, including travel health advice, to patients seeking medical treatment abroad.

  15. Electric Propulsion

    Next Generation Electric Propulsion (NGEP) technology development tasks are working towards advancing solar-powered electric propulsion systems and components to levels ready for transition to flight systems. Current tasks within NGEP include NASA's Evolutionary Xenon Thruster (NEXT), Carbon Based Ion Optics (CBIO), NSTAR Extended Life Test (ELT) and low-power Hall Effect thrusters. The growing number of solar electric propulsion options provides reduced cost and flexibility to capture a wide range of Solar System exploration missions. Benefits of electric propulsion systems over state-of-the-art chemical systems include increased launch windows, which reduce mission risk; increased deliverable payload mass for more science; and a reduction in launch vehicle size-- all of which increase the opportunities for New Frontiers and Discovery class missions. The Dawn Discovery mission makes use of electric propulsion for sequential rendezvous with two large asteroids (Vesta then Ceres), something not possible using chemical propulsion. NEXT components and thruster system under development have NSTAR heritage with significant increases in maximum power and Isp along with deep throttling capability to accommodate changes in input power over the mission trajectory. NEXT will produce engineering model system components that will be validated (through qualification-level and integrated system testing) and ready for transition to flight system development. NEXT offers Discovery, New Frontiers, Mars Exploration and outer-planet missions a larger deliverable payload mass and a smaller launch vehicle size. CBIO addresses the need to further extend ion thruster lifetime by using low erosion carbon-based materials. Testing of 30-cm Carbon-Carbon and Pyrolytic graphite grids using a lab model NSTAR thruster are complete. In addition, JPL completed a 1000 hr. life test on 30-cm Carbon-Carbon grids. The NSTAR ELT was a life time qualification test started in 1999 with a goal of 88 kg

    Purpose: To examine philosophical stances underpinning medical identity and assess the conceptual relationship between physician, medical practice and culture. Argument: Medical identity is about the ideals and moral positions that physicians take when justifying themselves. Medical identity...... hedonistic versus sentimentalist approaches to medical identity. The sociocultural philosophical analysis of medical identity can shed light on what it means conceptually for a physician to harbor beliefs associated with him/her being taken to be an autonomous professional. It is important because it touches...... on the meaning of being a compassionate, good and skilled physician, making its relevance to person-centered medicine self-evident. Conclusion: Medical identity should be analyzed with reference to literature, philosophy and medical practice in order for the physician to exercise a reflective position...

    Energy Technology Data Exchange (ETDEWEB)

    Norton, C.

    1981-09-14

    A controversial proposal to deregulate a major part of the electric utility industry could transform how electric power is produced. The proposal involves one-third of US energy consumption and violates the classic economic theory that tightly regulated natural monopolies serve society's needs best. Supporters of the proposal suggest that free-market competition may now be valid because new technologies and new power-supply sources can introduce innovation and efficiency into cost control. Many states, for example, allow utilities to pass capital costs through to their users. Alternative energy sources could include small hydro, wind power, and industrial cogeneration. Opponents, who question whether there really is a free market in energy production, suggest better regulation to protect consumers. Some of the opposition will come from utilities wanting to keep their captive markets. (DCK)

    NASA's Lewis Research Center undertook research toward a practical, economical battery with higher energy density. Borrowing from space satellite battery technology, Lewis came up with a nickel-zinc battery that promises longer life and twice the range of the lead-acid counterpart. Lewis researchers fabricated a prototype battery and installed it in an Otis P-500 electric utility van, using only the battery space already available and allowing battery weight equal to that of the va's conventional lead-acid battery

  2. Optoelectronic tweezers for medical diagnostics

    Kremer, Clemens; Neale, Steven; Menachery, Anoop; Barrett, Mike; Cooper, Jonathan M.

    2012-01-01

    Optoelectronic tweezers (OET) allows the spatial patterning of electric fields through selected illumination of a photoconductive surface. This enables the manipulation of micro particles and cells by creating non-uniform electrical fields that then produce dielectrophoretic (DEP) forces. The DEP responses of cells differ and can produce negative or positive (repelled or attracted to areas of high electric field) forces. Therefore OET can be used to manipulate individual cells and separate different cell types from each other. Thus OET has many applications for medical diagnostics, demonstrated here with work towards diagnosing Human African Trypanosomiasis, also known as sleeping sickness.

    Patient safety is a state of mind, not a technology. The technologies used in the medical setting represent tools that must be properly designed, used well, and assessed on an on-going basis. Moreover, in all settings, building a culture of safety is pivotal for improving safety, and many nontechnologic approaches, such as medication reconciliation and teaching patients about their medications, are also essential. This article addresses the topic of medication safety and examines specific strategies being used to decrease the incidence of medication errors across various clinical settings.

    Electrical stimulation has a long history of use in medicine dating back to 46 A.D. when the Roman physician Largus found the electrical discharge of torpedo fishes useful in the treatment of pain produced by headache and gout. A rival Greek physician, Dioscorides, discounted the value of the torpedo fish for headache relief but did recommend its use in the treatment of hemorrhoids. In 1745, the Leyden jar and various sized electrostatic generators were used to treat angina pectoris, epilepsy, hemiplegia, kidney stones, and sciatica. Benjamin Franklin used an electrical device to treat successfully a young woman suffering from convulsive fits. In the late 1800's battery powered hydroelectric baths were used to treat chronic inflammation of the uterus while electrified athletic supporters were advertised for the treatment of male problems. Fortunately, such an amusing early history of the simple beginnings of electrical stimulation did not prevent eventual development of a variety of useful therapeutic and rehabilitative applications of electrical stimulation. Over the centuries electrical stimulation has survived as a modality in the treatment of various medical disorders with its primary application being in the rehabilitation area. Recently, a surge of new interest in electrical stimulation has been kindled by the work of a Russian sport scientist who reported remarkable muscle strength and endurance improvements in elite athletes. Yakov Kots reported his research on electric stimulation and strength improvements in 1977 at a Canadian-Soviet Exchange Symposium held at Concordia University in Montreal. Since then an explosion of new studies has been seen in both sport science and in medicine. Based upon the reported works of Kots and the present surge of new investigations, one could be misled as to the origin of electrical stimulation as a technique to increase muscle strength. As a matter of fact, electric stimulation has been used as a technique to improve

    Panescu, Dorin; Nerheim, Max; Kroll, Mark

    2013-01-01

    TASER(®) conducted electrical weapons (CEW) deliver electrical pulses that can inhibit a person's neuromuscular control or temporarily incapacitate. TASER X26, X26P, and X2 are among CEW models most frequently deployed by law enforcement agencies. The X2 CEW uses two cartridge bays while the X26 and X26P CEWs have only one. The TASER X26P CEW electronic output circuit design is equivalent to that of any one of the two TASER X2 outputs. The goal of this paper was to analyze the nominal electrical outputs of TASER X26, X26P, and X2 CEWs in reference to provisions of several international standards that specify safety requirements for electrical medical devices and electrical fences. Although these standards do not specifically mention CEWs, they are the closest electrical safety standards and hence give very relevant guidance. The outputs of two TASER X26 and two TASER X2 CEWs were measured and confirmed against manufacturer and other published specifications. The TASER X26, X26P, and X2 CEWs electrical output parameters were reviewed against relevant safety requirements of UL 69, IEC 60335-2-76 Ed 2.1, IEC 60479-1, IEC 60479-2, AS/NZS 60479.1, AS/NZS 60479.2 and IEC 60601-1. Prior reports on similar topics were reviewed as well. Our measurements and analyses confirmed that the nominal electrical outputs of TASER X26, X26P and X2 CEWs lie within safety bounds specified by relevant requirements of the above standards.

    In theory, the Medical Council of India (MCI) determines the standards and qualifications of medical schools. It also sanctions curricula and ensures standards. Yet no standards exist on the mode of selection in medical schools, duration of study, course content, student stipends or period of internship. It takes 4.5 years to finish medical school. Students undergo preclinical, paraclinical, and clinical training. Most courses are in English which tends to favor the urban elite. Students cannot always communicate with patients in local languages. Textbooks often provide medical examples unrelated to India. Pedagogy consists mainly of lectures and rote learning predominates. Curricula tend not to provide courses in community health. Students pick up on the elitist attitudes of the faculty. For example, faculty do not put much emphasis on community health, individual health, equity in health care delivery, and teamwork. Further the education system is not patient oriented, but hospital or disease oriented. Faculty should train students in creating sanitation programs, knowing local nutritious foods, and in making community diagnoses. Yet they tend to be practitioners 1st then educators. Further faculty are not paid well and are not always invited to take part in improving curriculum, so morale is often low. Moreover experience in health planning and management issues is not required for administrators. In addition, medical schools are not well equipped with learning aids, libraries, or teaching staff. Tax revenues finance medical education. 75% of graduating physicians set up a private practice. Further many physicians go to urban areas. 34-57% emigrate to other countries. The problems of medical education will not be solved until the political and economic system becomes more responsive to the health needs of the people.

    In this paper, we propose analogies between medical discourse and Edward Said's "Orientalism." Medical discourse, like Orientalism, tends to favor institutional interests and can be similarly dehumanizing in its reductionism, textual representations, and construction of its subjects. To resist Orientalism, Said recommends that critics--"intellectuals"--adopt the perspective of exile. We apply Said's paradigm of intellectual-as-exile to better understand the work of key physician-authors who cross personal and professional boundaries, who engage with patients in mutually therapeutic relationships, and who take on the public responsibility of representation and advocacy. We call these physician-authors "medical intellectuals" and encourage others to follow in their path.

    Electrical stimulation of the nervous tissue has been proposed as a method to treat some neurological disorders, such as epilepsy. Epileptic seizures result from excessive, synchronous, abnormal firing patterns of neurons that are located predominantly in the cerebral cortex. Many people with epilepsy continue presenting seizures even though they are under regimens of antiepileptic medications. An alternative therapy for treatment resistant epilepsy is cerebral electrical stimulation. The present study is focused to review the effects of different types of electrical stimulation and specifically changes in amino acids.

    Ultrasound speckle is a granular texture pattern appearing in ultrasound imaging. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasound-based medical imaging technique of the tissue electrical conductivity. It is based on the application of an ultrasound wave in a medium placed in a magnetic field and on the measurement of the induced electric current due to Lorentz force. Similarly to ultrasound imaging, we hypothesized that a speckle could be observed with Lorentz force electrical impedance tomography imaging. In this study, we first assessed the theoretical similarity between the measured signals in Lorentz force electrical impedance tomography and in ultrasound imaging modalities. We then compared experimentally the signal measured in both methods using an acoustic and electrical impedance interface. Finally, a bovine muscle sample was imaged using the two methods. Similar speckle patterns were observed. This indicates the existence ...

    The Medical Renaissance started as the regular Renaissance did in the early 1400s and ended in the late 1600s. During this time great medical personalities and scholar humanists made unique advances to medicine and surgery. Linacre, Erasmus, Leonicello and Sylvius will be considered first, because they fit the early classic Renaissance period. Andreas Vesalius and Ambroise Paré followed thereafter, making outstanding anatomical contributions with the publication of the "Human Factory" (1543) by Vesalius, and describing unique surgical developments with the publication of the "The Apologie and Treatise of Ambroise Paré." At the end of the Renaissance and beginning of the New Science, William Harvey, noted British medical doctor and cardiovascular researcher, discovered the general circulation. He published his findings in "The Motu Cordis" in 1628 (Figure 1). The Medical Renaissance, in summary, included a great number of accomplished physicians and surgeons who made especial contributions to human anatomy; Vesalius assembled detailed anatomical information; Paré advanced surgical techniques; and Harvey, a medical genius, detailed the circulatory anatomy and physiology.

    2013-01-01

    Glaucoma is a common eye condition that affects millions of individuals worldwide, making it the second-leading cause of blindness. Because glaucoma is associated with increased IOP level, the primary goal in treatment of glaucoma includes lowering IOP to prevent further progression of the disease. While various surgical interventions exist, medical therapy is currently the first line of treatment. Medical treatment of glaucoma includes topical beta-blockers, alpha-2 agonists, prostaglandins, parasympathomimetics and CAIs. Anti-glaucoma agents help reduce IOP by affecting the production of aqueous humor or increasing the outflow of aqueous through the trabecular or uveoscleral pathway. Choosing an appropriate medical regimen can be challenging and various factors such as efficacy, safety, cost and patient compliance must be considered. First-line treatment is often topical beta-blockers or prostaglandin analogs. However, beta-blocking agents can be associated with systemic side effects and need to be used cautiously in patients with serious concomitant cardiopulmonary disease. Alpha-2 agonists and parasympathomimetics are often considered second- or third-line treatment options but good adjunctive agents. Oral CAIs are often indicated for patients with elevated IOP in an acute setting or for patients resistant to other glaucoma medications and patients who are not good surgical candidates.

    Since the introduction of the X-ray scanner into radiology almost 25 years ago, non-invasive imaging has become firmly established as an essential tool in the diagnosis of disease. Fully three-dimensional imaging of internal organs is now possible, b and for studies which explore the functional status of the body. Powerful techniques to correlate anatomy and function are available, and scanners which combine anatomical and functional imaging in a single device are under development. Such techniques have been made possible through r ecent technological and mathematical advances. This series of lectures will review both the physical basis of medical imaging techniques using X-rays, gamma and positron emitting radiosiotopes, and nuclear magnetic resonance, and the mathematical methods used to reconstruct three-dimentional distributions from projection data.

  15. The origins of medical physics.

    Science.gov (United States)

    Duck, Francis A

    2014-06-01

    The historical origins of medical physics are traced from the first use of weighing as a means of monitoring health by Sanctorius in the early seventeenth century to the emergence of radiology, phototherapy and electrotherapy at the end of the nineteenth century. The origins of biomechanics, due to Borelli, and of medical electricity following Musschenbroek's report of the Leyden Jar, are included. Medical physics emerged as a separate academic discipline in France at the time of the Revolution, with Jean Hallé as its first professor. Physiological physics flowered in Germany during the mid-nineteenth century, led by the work of Adolf Fick. The introduction of the term medical physics into English by Neil Arnott failed to accelerate its acceptance in Britain or the USA. Contributions from Newton, Euler, Bernoulli, Nollet, Matteucci, Pelletan, Gavarret, d'Arsonval, Finsen, Röntgen and others are noted. There are many origins of medical physics, stemming from the many intersections between physics and medicine. Overall, the early nineteenth-century definition of medical physics still holds today: 'Physics applied to the knowledge of the human body, to its preservation and to the cure of its illnesses'.

    Our whole industrial civilization depends upon cheap energy streaking out in all directions and under fingertip controls—and that would be very difficult without electric current. It would take enormous ingenuity to find substitutes. If all electricity were shut off, then all electronic devices would be dead. Electric lights would darken. Aluminum would become a rare metal. All factories would have to develop power sources on the spot and would have to switch to primitive, mechanical controls. Every house and every farm would have to give up items we have come to take for granted—not only electric lights, but electric irons, electric toasters, electric water pumps, electric control of furnaces, and so on.

    Information and communication technology (ICT) and mechatronics play a basic role in medical robotics and computer-aided therapy. In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery. Localization systems also provide treatments in radiotherapy and radiosurgery with high precision. Virtual or augmented reality plays a role for both surgical training and planning and for safe rehabilitation in the first stage of the recovery from neurological diseases. Also, in the chronic phase of motor diseases, robotics helps with special assistive devices and prostheses. Although, in the past, the actual need and advantage of navigation, localization, and robotics in surgery and therapy has been in doubt, today, the availability of better hardware (e.g., microrobots) and more sophisticated algorithms(e.g., machine learning and other cognitive approaches)has largely increased the field of applications of these technologies,making it more likely that, in the near future, their presence will be dramatically increased, taking advantage of the generational change of the end users and the increasing request of quality in health-care delivery and management.

    Science.gov (United States)

    Proietti, Riccardo; Sagone, Antonio

    2011-01-01

    Implantable defibrillators are lifesavers and have improved mortality rates in patients at risk of sudden death, both in primary and secondary prevention. However, they are unable to modify the myocardial substrate, which remains susceptible to life-threatening ventricular arrhythmias. Electrical storm is a clinical entity characterized the recurrence of hemodynamically unstable ventricular tachycardia and/or ventricular fibrillation, twice or more in 24 hours, requiring electrical cardioversion or defibrillation. With the arrival of the implantable cardioverter-defibrillator, this definition was broadened, and electrical storm is now defined as the occurrence of three or more distinct episodes of ventricular tachycardia or ventricular fibrillation in 24 hours, requiring the intervention of the defibrillator (anti-tachycardia pacing or shock). Clinical presentation can be very dramatic, with multiple defibrillator shocks and hemodynamic instability. Managing its acute presentation is a challenge, and mortality is high both in the acute phase and in the long term. In large clinical trials involving patients implanted with a defibrillator both for primary and secondary prevention, electrical storm appears to be a harbinger of cardiac death, with notably high mortality soon after the event. In most cases, the storm can be interrupted by medical therapy, though transcatheter radiofrequency ablation of ventricular arrhythmias may be an effective treatment for refractory cases. This narrative literature review outlines the main clinical characteristics of electrical storm and emphasises critical points in approaching and managing this peculiar clinical entity. Finally focus is given to studies that consider transcatheter ablation therapy in cases refractory to medical treatment. PMID:21468247

    Medical telesensors are self-contained integrated circuits for measuring and transmitting vital signs over a distance of approximately 1-2 meters. The circuits are unhoused and contain a sensor, signal processing and modulation electronics, a spread-spectrum transmitter, an antenna and a thin-film battery. We report on a body-temperature telesensor, which is sufficiently small to be placed on a tympanic membrane in a child's ear. We also report on a pulse-oximeter telesensor and a micropack receiver/long- range transmitter unit, which receives form a telesensor array and analyzes and re-transmits the vital signs over a longer range. Signal analytics are presented for the pulse oximeter, which is currently in the form of a finger ring. A multichip module is presented as the basic signal-analysis component. The module contains a microprocessor, a field=programmable gate array, memory elements and other components necessary for determining trauma and reporting signals.

    The cannabis plant has been known to humanity for centuries as a remedy for pain, diarrhea and inflammation. Current research is inspecting the use of cannabis for many diseases, including multiple sclerosis, epilepsy, dystonia, and chronic pain. In inflammatory conditions cannabinoids improve pain in rheumatoid arthritis and:pain and diarrhea in Crohn's disease. Despite their therapeutic potential, cannabinoids are not free of side effects including psychosis, anxiety, paranoia, dependence and abuse. Controlled clinical studies investigating the therapeutic potential of cannabis are few and small, whereas pressure for expanding cannabis use is increasing. Currently, as long as cannabis is classified as an illicit drug and until further controlled studies are performed, the use of medical cannabis should be limited to patients who failed conventional better established treatment.

    1996-12-31

    A revolution has been sweeping through the electricity supply business in Australia in the past decade and especially in the past five years. Electricity suppliers were early adherents to the pursuit of economic reform, beginning a drive towards greater efficiency in the mid-1980s and accelerating the process as government, pushed in turn by industry and commerce, took up pursuit of competitive energy markets, including radical restructuring of the State-owned utility organizations. The aim of this paper is to provide an overview of the electricity supply business. It include an outline of the major challenges confronting the electricity supply business in Australia, particularly as a result of the introduction of competitive markets in electricity and natural gas. Deregulation will see the providers of electricity and gas reposition themselves as organizations able to supply the total energy needs of customers. A de-regulated electricity market also offers cogeneration plants new opportunities to sell surplus electricity to generators, distribution businesses or directly to customers. The major frontiers facing the electricity supply business in Australia is seen to be that of productively channelling change. How this is handled has substantial implications for those who purchase electricity, suppliers of fuel to electricity generators or rivals in the marketplace. (author).

    Electrical signaling, short-term memory and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since the XIX century. We found that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The closing time of Venus flytrap by electrical stimulation is the same as mechanically induced closing. Transmission of a single electrical charge between a lobe and the midrib causes closure of the trap and induces an electrical signal propagating between both lobes and midrib. The Venus flytrap can accumulate small subthreshold charges, and when the threshold value is reached, the trap closes. Repeated application of smaller charges demonstrates the summation of stimuli. The cumulative character of electrical stimuli points to the existence of short-term electrical memory in the Venus flytrap.

  11. Economics of electricity

    Erdmann, G.

    2015-08-01

    The following text is an introduction into the economic theory of electricity supply and demand. The basic approach of economics has to reflect the physical peculiarities of electric power that is based on the directed movement of electrons from the minus pole to the plus pole of a voltage source. The regular grid supply of electricity is characterized by a largely constant frequency and voltage. Thus, from a physical point of view electricity is a homogeneous product. But from an economic point of view, electricity is not homogeneous. Wholesale electricity prices show significant fluctuations over time and between regions, because this product is not storable (in relevant quantities) and there may be bottlenecks in the transmission and distribution grids. The associated non-homogeneity is the starting point of the economic analysis of electricity markets.

Métodos: Investigación cualitativa longitudinal basada en entrevistas en profundidad (desde julio de 2001 hasta diciembre de 2003, desarrolladas en el Hospital Italiano de Buenos Aires (Argentina. Se entrevistó a 20 cardiólogos de atención ambulatoria con perfiles profesionales diversos (muestreo intencional antes, durante y al finalizar la implementación del sistema (10 entrevistas por etapa. El análisis fue realizado por 2 investigadores independientes y las categorías refinadas conjuntamente. Resultados: Antes y durante la primera etapa de la implementación los médicos esperaban que el sistema mejorara los procesos administrativos de la atención y la disponibilidad de los datos individuales que cada uno había registrado en consultas anteriores, pero no imaginaban que la información colectiva pudiera modificar los aspectos médicos de la atención. Al finalizar la implementación, en cambio, percibieron que el sistema les permitía acceder a una visión integral del paciente que modificaba el desempeño profesional. Durante la implementación, los médicos opusieron el contacto con el paciente a la interacción con el ordenador, oposición que les impide categorizar su uso como parte del acto médico y considerar los datos del sistema como signos directos del paciente. Conclusiones: Con la implementación, los médicos modificaron su perspectiva sobre el registro médico electrónico, llegando a percibirlo como un auxiliar para la práctica médica. El valor que se asigna al sistema depende de su relevancia dentro del marco institucional.Objectives: To explore physicians' beliefs about a computerized ambulatory medical record system at different stages of its implementation.

    2002-12-01

    Full Text Available Background. Due to restrictions imposed on a clinical freedom, interest for professionalism in healthcare has been getting bigger not only in medicine literature and various mass media but also in teaching and organisation of healthcare. Professionalism stands not only for a medicine’s contract with society, recognition of a physician status, privilege and monopoly but also for a genuine physician’s commitment to professional responsibilities.Analysis. In 2002 European and American associations approved a document on medical professionalism in the new millenium, so-called Physician Charter. This document includes fundamental principles of professionalism such as altruism, patient autonomy and social justice. In particular, it analyses a physician’s professional competency, honesty with patients, patient confidentiality, appropriate relations with patients, improvements regarding a healthcare quality, healthcare access, just distribution of finite funds, commitment to scientific knowledge, trust maintenance by managing conflicts of interest and a professional responsibility.Conclusions. Physician’s professionalism means philosophycal and sociological analysis of his/her profession and its position in a society. It includes a concern for improvements of his/ her own scientific knowledge, skills, a genuine ethic interest for an individual patient bearing in mind principles of equality and justice in society. Whether performing an organisational and public work or participating in professional health organizations, physician’s interest for a patient must prevail.

    Wheatley, John C.; Swift, Gregory W.; Migliori, Albert

    1986-01-01

    A thermoacoustic magnetohydrodynamic electrical generator includes an intrinsically irreversible thermoacoustic heat engine coupled to a magnetohydrodynamic electrical generator. The heat engine includes an electrically conductive liquid metal as the working fluid and includes two heat exchange and thermoacoustic structure assemblies which drive the liquid in a push-pull arrangement to cause the liquid metal to oscillate at a resonant acoustic frequency on the order of 1,000 Hz. The engine is positioned in the field of a magnet and is oriented such that the liquid metal oscillates in a direction orthogonal to the field of the magnet, whereby an alternating electrical potential is generated in the liquid metal. Low-loss, low-inductance electrical conductors electrically connected to opposite sides of the liquid metal conduct an output signal to a transformer adapted to convert the low-voltage, high-current output signal to a more usable higher voltage, lower current signal.

  7. Essays on electricity theft

    Science.gov (United States)

    Steadman, Keva Ullanda

    Electricity theft is a relatively unknown crime with high economic costs. In this dissertation, I try to identify the factors that motivate persons to steal electricity. First, I use a panel dataset of 97 countries spanning the five year period 2003--2007 to estimate a model that describes the effect of the unemployment rate, GDP per capita, male population and urbanization on theft, robbery and homicide rates. The results are consistent with previous empirical work on crime and economic opportunity. The second and main contribution of this paper is to estimate the same model using distribution loss as a proxy for electricity theft. The results show that the unemployment rate, a key explanatory economic factor for crime, cannot explain variation in electricity theft, although there is some evidence, albeit weak, supporting correlation in rich countries. Therefore, policies that target the reduction of property crime through a reduction in unemployment will have no effect on electricity theft. The third contribution relates to the role that political institutions play in the incentives to steal electricity. After control for socioeconomic factors, I find that there is no relationship between political governance indicators and electricity theft. In the second and third chapters, I compare the United States, a high income, low electricity theft country with Jamaica, a middle income, high electricity theft country. The effect of unemployment on electricity theft mirrors the results found in the first chapter. In the United States, electricity theft is affected by changes in economic conditions but in Jamaica, it is not. These results suggest that the state of institutions plays a role in how social norms are determined. Poor countries will be more likely than rich countries to have weak institutions with social norms that encourage electricity theft.

    Electrical impedance tomography (EIT) is a powerful tool for mapping the conductivity distribution of estimated objects. The EIT system is entirely implemented by electrical technique, so it is a relatively cheap system and data can be collected very rapidly. But it has few commercially medical EIT systems available. This is because impedance image unable to achieve the essential spatial resolution and this technique has an intrinsically poor signal to noise ratio. In this paper, we have developed a high performance rotative EIT system (REIT) for expanding the independent measurements. By rotate the electrodes successive, REIT could change the position of electrodes and acquire more measurement data. This rotative measurement method not only can increase the resolution of impedance images, but also reduce the complexity of measurement system. We hope the improvement of REIT will bring some help in electrical impedance tomography.

    Full Text Available After the collapse of the former Soviet Union and restoration of independence of Georgia, the economy faced numerous problems and without settling those problems it was impossible to build a market economy in the country. Before, we could hardly imagine that we would be challenged to create an independent state statistics body in terms of building the market economy. In this light, post-Soviet Georgia partially used experience gained in the independent Democratic Republic of Georgia (1981-1921. The statistics body of that time could not manage to provide the country with social-economic information fully due to short period of functioning but taking into account the necessity of its existence, withdrawal from departmental subordination, necessity of participation of scientists in the statistics board, etc. proved to be useful for the independent post-Soviet Georgia. Although, imperfect attitude towards the statistics body in the post-Soviet period was evident from permanent changes of its status and its subordination to one of the Ministries. Parallel studies show that other negative experiences of the 1920s as well as modern international experiences were underestimated, which linked numerous difficulties revealed during the development of post-Soviet Georgia to disorganization of the statistical system.

  13. Electrical Networks: An Introduction

    Science.gov (United States)

    Pahwa, S.; Youssef, M.; Scoglio, C.

    A world without electricity is beyond our imagination. Starting from the prehistoric times, man has made much progress in every walk of life. We have become accustomed to getting everything at the flick of a switch, touch of a button, or turn of a knob. While we have become so used to enjoying the benefits of electricity, it is not easy to imagine how electricity travels from its source to our homes and offices. It sometimes has to cover large distances through a complex network of transmission lines and power substations to provide us the facilities and entertainment that we take for granted. This network which transports electricity from the source to the consumers is called the electrical network. The electrical network is a collective term for different components such as transformers, transmission lines, substations, and different stages and sub-networks devoted to generation, transmission, and distribution. Sometimes, there may be sub-transmission and secondary distribution networks too. A simple schematic of an electric network is shown in Fig. 8.1. In the past decade, analysis of the electrical power system as a complex network has been an evolving and challenging topic of research.

  18. Electricity Storage. Technology Brief

    2012-04-15

    Electricity storage is a key technology for electricity systems with a high share of renewables as it allows electricity to be generated when renewable sources (i.e. wind, sunlight) are available and to be consumed on demand. It is expected that the increasing price of fossil fuels and peak-load electricity and the growing share of renewables will result in electricity storage to grow rapidly and become more cost effective. However, electricity storage is technically challenging because electricity can only be stored after conversion into other forms of energy, and this involves expensive equipment and energy losses. At present, the only commercial storage option is pumped hydro power where surplus electricity (e.g. electricity produced overnight by base-load coal or nuclear power) is used to pump water from a lower to an upper reservoir. The stored energy is then used to produce hydropower during daily high-demand periods. Pumped hydro plants are large-scale storage systems with a typical efficiency between 70% and 80%, which means that a quarter of the energy is lost in the process. Other storage technologies with different characteristics (i.e. storage process and capacity, conversion back to electricity and response to power demand, energy losses and costs) are currently in demonstration or pre-commercial stages and discussed in this brief report: Compressed air energy storage (CAES) systems, Flywheels; Electrical batteries; Supercapacitors; Superconducting magnetic storage; and Thermal energy storage. No single electricity storage technology scores high in all dimensions. The technology of choice often depends on the size of the system, the specific service, the electricity sources and the marginal cost of peak electricity. Pumped hydro currently accounts for 95% of the global storage capacity and still offers a considerable expansion potential but does not suit residential or small-size applications. CAES expansion is limited due to the lack of suitable

  19. Electric turbocompound control system

    Energy Technology Data Exchange (ETDEWEB)

    Algrain, Marcelo C. (Dunlap, IL)

    2007-02-13

    Turbocompound systems can be used to affect engine operation using the energy in exhaust gas that is driving the available turbocharger. A first electrical device acts as a generator in response to turbocharger rotation. A second electrical device acts as a motor to put mechanical power into the engine, typically at the crankshaft. Apparatus, systems, steps, and methods are described to control the generator and motor operations to control the amount of power being recovered. This can control engine operation closer to desirable parameters for given engine-related operating conditions compared to actual. The electrical devices can also operate in "reverse," going between motor and generator functions. This permits the electrical device associated with the crankshaft to drive the electrical device associated with the turbocharger as a motor, overcoming deficient engine operating conditions such as associated with turbocharger lag.

    2011-04-01

    The high number of false positive alarms has long been known to be a serious problem in critical care medicine - yet it remains unresolved. At the same time, threats to patient safety due to missing or suppressed alarms are being reported. The purpose of this paper is to present results from a workshop titled "Too many alarms? Too few alarms?" organized by the Section Patient Monitoring and the Workgroup Alarms of the German Association of Biomedical Engineering of the Association for Electrical, Electronic and Information Technologies. The current situation regarding alarms and their problems in intensive care, such as lack of clinical relevance, alarm fatigue, workload increases due to clinically irrelevant alarms, usability problems in alarm systems, problems with manuals and training, and missing alarms due to operator error are outlined, followed by a discussion of solutions and strategies to improve the current situation. Finally, the need for more research and development, focusing on signal quality considerations, networking of medical devices at the bedside, diagnostic alarms and predictive warnings, usability of alarm systems, education of healthcare providers, creation of annotated clinical databases for testing, standardization efforts, and patient monitoring in the regular ward, are called for.

  8. Advances in the medical management of the severe cutaneous radiation syndrome

    Energy Technology Data Exchange (ETDEWEB)

    2000-05-01

    The cutaneous radiation syndrome is a dose dependant complex pathological syndrome which follows a brief localized exposure and characterized by erythema, swelling, moist desquamation, ulceration and necrosis (25-30 Gy). Highly penetrating gamma radiation induces severe dose dependent lesions involving skin, subcutaneous tissue, muscle, vessels, nerves and occasionally, bony structures. The classical treatment of this syndrome includes the debridement of devitalized tissues, the application of bacteriostatic agents coated in non-adherent dressings, opiate-based drugs and in some cases the use of non-steroidal anti-inflammatory drugs. For ulceration and necrosis treatment, the classical surgery is ulcerectomy, necrectomy and amputation for the distal extremity injuries. For the profound et large necrosis, the lesion should be excised and the wound bed covered with a good quality, full-thickness skin graft. Unfortunately the delayed of appearance of this syndrome results often in non specialized medical treatment. Furthermore, because of the chronic evolution (months or years) the management of the cutaneous radiation syndrome has not been considered as a priority for the medical management. Recent accident like the Georgian accident demonstrated that new techniques such as artificial skin graft could change significantly patient prognosis. This technique is routinely used for thermal burn in specialized burn units. We realized the first application of this methodology in the field of radiopathology. An important factor of this technique is that in the case of recurrence of radionecrosis. Often observed, using this technique further grafting may be employed. However the success of this procedure depends on an effective control of the infection. These has sadly been illustrated in the last accident case in Peru where it was impossible to perform the artificial skin graft due to the persistence of a non-eradicated local infection. Whether this particular approach has a

Both antennas yield equal quality factors, which are about 1.5 times the Chu lower bound, but quite different cross-polarization characteristics.......This paper introduces a novel electrically small spherical meander antenna. Horizontal sections of the meander are composed of wire loops, radii of which are chosen so that the whole structure is conformal to a sphere of radius a. To form the meander the loops are connected by wires at a meridian...... plane. The antenna operates as an electric dipole, i.e. it radiates the TM10 spherical mode. The antenna is self-resonant and can be matched to a wide range of input feed lines without an external matching network.

    Futurist writing about technology emerged in the late 19th century at the same time as new kinds of electrical technology were making utopian futures seem practically attainable. Electrical writers and novelists alike thus borrowed from the popular "science" fiction of Jules Verne, Edward Bellamy and others to try to create self-fulfilling prophecies of a future in which electrical gadgets and machines met all major practical needs of civilization. To the extent that many parts of our world are populated by the hardware that they forecast, they succeeded in their goal.

  18. Coaxial Electric Heaters

    Science.gov (United States)

    Strekalov, Dmitry; Matsko, Andrey; Savchenkov, Anatoliy; Maleki, Lute

    2008-01-01

    Coaxial electric heaters have been conceived for use in highly sensitive instruments in which there are requirements for compact heaters but stray magnetic fields associated with heater electric currents would adversely affect operation. Such instruments include atomic clocks and magnetometers that utilize heated atomic-sample cells, wherein stray magnetic fields at picotesla levels could introduce systematic errors into instrument readings. A coaxial electric heater is essentially an axisymmetric coaxial cable, the outer conductor of which is deliberately made highly electrically resistive so that it can serve as a heating element. As in the cases of other axisymmetric coaxial cables, the equal magnitude electric currents flowing in opposite directions along the inner and outer conductors give rise to zero net magnetic field outside the outer conductor. Hence, a coaxial electric heater can be placed near an atomic-sample cell or other sensitive device. A coaxial electric heater can be fabricated from an insulated copper wire, the copper core of which serves as the inner conductor. For example, in one approach, the insulated wire is dipped in a colloidal graphite emulsion, then the emulsion-coated wire is dried to form a thin, uniform, highly electrically resistive film that serves as the outer conductor. Then the film is coated with a protective layer of high-temperature epoxy except at the end to be electrically connected to the power supply. Next, the insulation is stripped from the wire at that end. Finally, electrical leads from the heater power supply are attached to the exposed portions of the wire and the resistive film. The resistance of the graphite film can be tailored via its thickness. Alternatively, the film can be made from an electrically conductive paint, other than a colloidal graphite emulsion, chosen to impart the desired resistance. Yet another alternative is to tailor the resistance of a graphite film by exploiting the fact that its resistance

    Manipulation of magnetically ordered states by electrical means is a promising approach towards novel spintronics devices. We report on the electric control of surface magnetism in Cr2O3 thin films and uniaxial anisotropy in ferroelectric/ferromagnetic heterostructures, respectively. Artificial magnetoelectricity is realized in a BaTiO3/Fe heterostructure. Here, thermally induced coercivity changes of the Fe hysteresis loop are used to derive the stress imposed by the ferroelectric BaTiO3 substrate on the adjacent Fe film. Electrically induced coercivity changes give rise to a giant magnetoelectric susceptibility in the vicinity of the magnetic coercive field.

    Electrical injury is a devastating and hard to treat clinical lesion. Fully understanding the pathophysiology of electrical trauma is still a challenge for clinicians and scientists. Further elucidating the natural history of this form of tissue injury could be helpful in improving limb salvage and offering stage-appropriate therapy. Multi-spectral imaging technique is a non-invasive technology that can be used to determine optical properties of tissues in and adjacent to injury. Images at different wavelengths can provide essential information related to the pathophysiological condition of the tissue. To promote the applicability of this technique in medical diagnosis, we built a complete experimental model of electrical injury. In this model, electrical injuries were created by a reliable high-tension shock system at preset voltage or current. A thermal camera recorded the change of skin temperature during the electrical shock. Then, a high-resolution spectral imaging system based on structured illumination was used to capture images for post analysis to extrapolate optical properties of the tissue. To test accuracy, this imaging system was calibrated by using a set of epoxy phantoms with known optical properties. In this paper, the results of experiments conducted on rats and discussions on the systemic changes in tissue optical properties before and after electrical shock are presented.

    Full Text Available Training physicians who are expert in many medical aspects is the most improtant mission of medical universities. One of these aspects, is professional behavior achievement. One of the important goals in training of ethics, is recognition of conflicts in different parts of ethics and having logical viewpoint for resolving and analyzing these conflicts. This descriptive and analytical study was done to evaluate the efficacy of medical ethics education in medical students´ professional attitudes improvement. One hundred and two medical students were selected randomly in different steps of education and were questioned and their opinions correlation with stage of education and gender were evaluated. There was a significant difference between female viewpoint (in roles of ethic course which is presented in preclinical step in professional attitude improvement (P = 0.009 and also a significant difference was seen in the viewpoint score between student stage with intern stage (P = 0.031. Medical students in educational student stage believe ethic course improve medical professionalism. Since there is no special course to train medical students in professionalism, some interventions are required in this field to improve this aspect of physicians' professional life.

  14. Electrically driven optical antennas

    Kern, Johannes; Kullock, René; Prangsma, Jord; Emmerling, Monika; Kamp, Martin; Hecht, Bert

    2015-09-01

    Unlike radiowave antennas, so far optical nanoantennas cannot be fed by electrical generators. Instead, they are driven by light or indirectly via excited discrete states in active materials in their vicinity. Here we demonstrate the direct electrical driving of an in-plane optical antenna by the broadband quantum-shot noise of electrons tunnelling across its feed gap. The spectrum of the emitted photons is determined by the antenna geometry and can be tuned via the applied voltage. Moreover, the direction and polarization of the light emission are controlled by the antenna resonance, which also improves the external quantum efficiency by up to two orders of magnitude. The one-material planar design offers facile integration of electrical and optical circuits and thus represents a new paradigm for interfacing electrons and photons at the nanometre scale, for example for on-chip wireless communication and highly configurable electrically driven subwavelength photon sources.

    2015-01-01

    The essays in this book, written by researchers from both humanities and sciences, describe various theoretical and experimental approaches to adding medical ethics to a machine in medical settings. Medical machines are in close proximity with human beings, and getting closer: with patients who are in vulnerable states of health, who have disabilities of various kinds, with the very young or very old, and with medical professionals. In such contexts, machines are undertaking important medical tasks that require emotional sensitivity, knowledge of medical codes, human dignity, and privacy. As machine technology advances, ethical concerns become more urgent: should medical machines be programmed to follow a code of medical ethics? What theory or theories should constrain medical machine conduct? What design features are required? Should machines share responsibility with humans for the ethical consequences of medical actions? How ought clinical relationships involving machines to be modeled? Is a capacity for e...

    Hybrid electric power trains may revolutionize today's ground passenger vehicles by significantly improving fuel economy and decreasing emissions. The NASA Lewis Research Center is working with industry, universities, and Government to develop and demonstrate a hybrid electric vehicle. Our partners include Bowling Green State University, the Cleveland Regional Transit Authority, Lincoln Electric Motor Division, the State of Ohio's Department of Development, and Teledyne Ryan Aeronautical. The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

    We have investigated the impact of strong (∼10{sup 4} V/cm) electric fields on the development of Zn whiskers. The original samples, with considerable whisker infestation were cut from Zn-coated steel floors and then exposed to electric fields stresses for 10-20 hours at room temperature. We used various electric field sources, from charges accumulated in samples irradiated by: (1) the electron beam of a scanning electron microscope (SEM), (2) the electron beam of a medical linear accelerator, and (3) the ion beam of a linear accelerator; we also used (4) the electric field produced by a Van der Graaf generator. In all cases, the exposed samples exhibited a considerable (tens of percent) increase in whiskers concentration compared to the control sample. The acceleration factor defined as the ratio of the measured whisker growth rate over that in zero field, was estimated to approach several hundred. The statistics of lengths of e-beam induced whiskers was found to follow the log-normal distribution known previously for metal whiskers. The observed accelerated whisker growth is attributed to electrostatic effects. These results offer promise for establishing whisker-related accelerated life testing protocols.

    Full Text Available The quality of medical texts provided to general public on the Internet is a serious issue nowadays. Unfortunately the only feasible way to approve the adequacy of the medical information content is human verification today. Best practices in medicine are systematically captured by medical guidelines (MGLs, which are provided by renowned medical societies. We propose a simple approach to exploiting MGL content as ’gold standard’ for the assessment of content quality in medical web sites (WS, based on the idea that the information content is reflected in the domain terminology used. Concept candidates discovered in a MGL and in the tested web pages are matched to the UMLS terminological system. In a small case study, MGLs and WSs have been analyzed for similarity at term and concept level. The research is a step towards automated evaluation of WS content on the basis of MGLs as the quality standard.

  19. An Electric Method for Qualifying Cytogenetic Slides

    Directory of Open Access Journals (Sweden)

    Saeed Khamnei

    2011-01-01

    Full Text Available Cytogenetics is a branch of genetics that involves critical applications in medical decisions. The procedures involved take cells with chromosomes and rupture them on the slide to release their chromosomes in metaphase spreadings. Usually the slide contains few metaphase spreadings and plenty of intact cells, so finding and analyzing metaphase spreadings are difficult. It is for this reason that many investigations search for innovations that optimize chromosome spreading and facilitate cytogenetic studies. To aid rupturing cells in cytogenetic slide preparation, Pulsed Electric Fields (PEFs could be used. PEFs are a kind of electric fields, which affect the cell membrane in a way that can lead to cell lysis. These effects are currently the basis of applications such as nonthermal pasteurization. Therefore, applying PEFs to cell suspension of the cytogenetic experiments would probably lyse all the cells, yielding a clear slide with many metaphase spreadings.

  3. Electric generators: Roesel

    Energy Technology Data Exchange (ETDEWEB)

    Segaser, C.L.

    1977-04-01

    A new and unique type of electrical generator is described that will provide constant frequency output (within 0.01% or better) regardless of rotational speed variations. It accomplishes this with no added bulk over conventional generators, and with excellent efficiency. The same principle that permits constant frequency output also provides the means for output voltage regulation with varying drive speed and/or varying load. Onsite power generation aspects of the Integrated Community Energy Systems (ICES) concept include the requirement to follow community electric loads and the possible use of internal combustion piston engines with waste heat recovery to drive electric generators. The diesel engine is a prime candidate from commercially available technologies for which part-load shaft efficiency is better at reduced speed than for constant-speed operation required by conventional AC generators. The unique characteristics of the Roesel generator allow prime mover speed to decrease with load and offer improved engine-generator system efficiency in ICES applications.

It defines responsibilities and describes actions performed by the government and electric utilities in planning for, and in operations during, national emergencies. The EEPA Handbook is reissued periodically to describe organizational changes, to assign new duties and responsibilities, and to clarify the responsibilities of the government to direct and coordinate the operations of the electric utility industry under emergencies declared by the President. This Handbook is consistent with the assumptions, policies, and procedures contained in the National Plan for Emergency Preparedness. Claimancy and restoration, communications and warning, and effects of nuclear weapons are subjects covered in the appendices.

    Medical spas are different. We are not just selling medical and dermatology services; we are offering clients viable new solutions to their skin care, body care, and hair care challenges. Traditional medical marketing becomes blurred today, as the expansion and acceptance of medical spas helps you to effectively compete with traditional skin care clinics, salons, and spas, while offering more therapeutic treatments from professionally licensed doctors, nurses, aestheticians, massage therapists, spa professionals, and medical practitioners. We recommend that you make the choice to successfully and competitively become a market-driven medical spa with an annual strategic plan, rather than an operationally driven business.

  8. Electrical Conductivity in Textiles

    Science.gov (United States)

    2006-01-01

    Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA. Conductive fibers provide lightweight alternatives to heavy copper wiring in a variety of settings, including aerospace, where weight is always a chief concern. This is an area where NASA is always seeking improved materials. The fibers are also more cost-effective than metals. Expenditure is another area where NASA is always looking to make improvements. In the case of electronics that are confined to small spaces and subject to severe stress, copper is prone to breaking and losing connection over time. Flexible conductive fibers eliminate that problem. They are more supple and stronger than brittle copper and, thus, find good use in these and similar situations. While clearly a much-needed material, electrically conductive fibers are not readily available. The cost of new technology development, with all the pitfalls of troubleshooting production and the years of testing, and without the guarantee of an immediate market, is often too much of a financial hazard for companies to risk. NASA, however, saw the need for electrical fibers in its many projects and sought out a high-tech textile company that was already experimenting in this field, Syscom Technology, Inc., of Columbus, Ohio. Syscom was founded in 1993 to provide computer software engineering services and basic materials research in the areas of high-performance polymer fibers and films. In 1999, Syscom decided to focus its business and technical efforts on development of high-strength, high-performance, and electrically conductive polymer fibers. The company developed AmberStrand, an electrically conductive, low-weight, strong-yet-flexible hybrid metal-polymer YARN.

  9. Electricity consumption and electricity saving in the Swedish households

    Energy Technology Data Exchange (ETDEWEB)

    Bernstroem, B.M.; Eklund, Y.; Sjoeberg, L.

    1997-03-01

    The objective of the present study is to determine which factors influence electricity consumption behavior of Swedish households, the level of knowledge about electricity use and the willingness to pay for the use of electricity. In Sweden, as in many other developed countries, the need for electric power is constantly increasing. The major reason for this increase in electricity consumption is the lifestyle of a modern society. A feature in the nuclear power discussion is that the government in Sweden is having a hard time to establish how to phase-out all nuclear power plants by 2010. An additional major change in Swedish energy policy is the deregulation of the electricity market, which started in the beginning of 1996. There is an increased demand for strategies to save electricity among households. The results of this study stress the difficulties in reducing electricity consumption and to develop new electricity saving strategies in Sweden 125 refs, 6 figs, 21 tabs

  10. Electrical signaling and photosynthesis

    2011-01-01

    Mechanical irritation of trigger hairs and subsequent generation of action potentials have significant impact on photosynthesis and respiration in carnivorous Venus flytrap (Dionaea muscipula). Action potential-mediated inhibition of photosynthesis and stimulation of respiration is confined only to the trap and was not recorded in adjacent photosynthetic lamina. We showed that the main primary target of electrical signals on assimilation is in the dark enzymatic reaction of photosynthesis. Without doubt, the electrical signaling is costly, and the possible co-existence of such type of signals and photosynthesis in plant cell is discussed. PMID:21558815

    As people`s values change, the requirements imposed on products change as well. One value which is becoming increasingly important is that of an environmental orientation. Consumers are demanding that manufacturers supply information on the extent to which the production, use, and disposal of products negatively affect the natural environment. For industry, electricity is one of the factors of production. As such, it is also a commodity. The power industry must respond to the demands of consumers and be prepared to explain how electricity is generated

    In this paper, we apply the relationships between the macro and micro variables of traffic flow to develop an electricity consumption model for electric vehicular flow. We use the proposed model to study the quantitative relationships between the electricity consumption/total power and speed/density under uniform flow, and the electricity consumptions during the evolution processes of shock, rarefaction wave and small perturbation. The numerical results indicate that the proposed model can perfectly describe the electricity consumption for electric vehicular flow, which shows that the proposed model is reasonable.

In consequence, the contents of the museums, medical objects, is an aspect rather that a branch of the history of medicine.

  16. Electric Guitar and Violin

    Science.gov (United States)

    Gough, Colin

    Almost all the instruments described in this book have their origins in historical cultures dating back over many centuries. In contrast, the electric guitar and violin are clearly twentieth-century innovations. They are products of the electronics age following invention of the rectifying thermionic valve (tube) by John Ambrose Fleming in 1904, the amplifying triode valve (tube) by Lee de Forest in 1907, and the vacuum-filled amplifying valve (tube) by Irving Langmuir in 1915. By 1916, such valves were already being used in radio receivers, and important advances were being made in microphone, amplifier, and loudspeaker design. This, and the increasingly wide distribution of mains electricity in the 1920s, provided the technology and infrastructure for the development of the electric guitar and violin and their lower-pitched relations - the bass guitar, viola, cello, and string-bass. Although we focus here on the electric guitar and violin, almost everything discussed in this chapter is also relevant to their lower-pitched relations.

  4. Effectiveness of a worker-worn electric-field sensor to detect power-line proximity and electrical-contact.

    Science.gov (United States)

    Zeng, Shengke; Powers, John R; Newbraugh, Bradley H

    2010-06-01

    Construction workers suffer the most electrocutions among all industries. Currently, there are no electrical contact warning devices on the market to protect workers. This paper proposes a worker-worn electric-field sensor. As the worker is in proximity to, or in contact with, a live power-circuit, the sensor sets off an audible/visual warning alarm. The sensor also has the potential to wirelessly trip a wireless-capable circuit breaker, and to trigger a wireless transmitter to notify emergency response of an electrical contact. An experiment was conducted to measure electric-field variation on simulated human-wrists (10 defrosted hog-legs) in various proximities and in electrical-contact to a simulated power-circuit. The purpose of these tests was to determine the feasibility of developing a worker-worn electric-field detection sensor for use in protecting workers from contact with energized electrical conductors. This study observed a significant electric-field-magnitude increase as a hog-leg approaches the live-circuit, and the distinct electric-field-magnitude jump as the leg contacts with the live-circuit. The observation indicates that this sensor can be an effective device to warn the workers of electrical hazards. Additionally, the sensor has the potential to wirelessly trip a wireless-capable circuit-breaker and trigger a wireless transmitter (such as a cell phone) to notify an emergency response. The prompt notification prevents the worker from further injury caused by postponed medical-care. Widespread use of this sensor could lower electrocution and electrically related injury rates in the construction industry. (c) 2010 Elsevier Ltd. All rights reserved.

  5. Topics on electricity trade

    Energy Technology Data Exchange (ETDEWEB)

    Skytte, K.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

    Dehail, P; Duclos, C; Barat, M

    2008-07-01

    To identify the effects of application methods and indications of direct muscle electrostimulation on strength gain. Literature review and analysis of articles from Medline database with the following entries: muscular or neuromuscular, electromyostimulation, electrical stimulation, strengthening, strength training, immobilization, muscle dystrophy, bed-rest, bed-bound, knee or hip surgery, postoperative phase, cachexia, sarcopenia, and their French equivalent. Because of its specific muscle recruitment order, different from that of voluntary contraction, direct muscle electrostimulation is theoretically a complementary tool for muscle strengthening. It can be used in healthy subjects and in several affections associated with muscle function loss. Its interest seems well-established for post-traumatic or postsurgery lower-limb immobilizations but too few controlled studies have clearly shown the overall benefits of its application in other indications. Whatever the indication, superimposed or combined electrostimulation techniques are generally more efficient than electrostimulation alone. Even though widely used, the level of evidence for the efficiency of electromyostimulation is still low. For strength gains, it yielded no higher benefits than traditional strengthening methods. Its interest should be tested in medical affections leading to major muscle deconditioning or in sarcopenia.

Dispensing must be done in the correct time interval, at the correct user, with the correct drug and dose. We propose a smart medication dispenser that can satisfy these needs and provide a mechanism for supervision. In order to ensure that the dispensing process is error free, the concept of a new smart medication container is used. A smart medication container is “smart” as it holds the medication dispensing parameters for the drugs it contains: dispensing time and date and name. Based on this information, the actual dispensing is done.

    2015-01-01

    Medical leadership is a popular topic in the Netherlands, and several interest groups now incorporate medical leadership into postgraduate medical education. However, there is no consensus on what this concept entails. By conducting a discourse analysis, a qualitative method which uses language and text to reveal existing viewpoints, this article reveals three perspectives on medical leadership: administrative leadership, leadership within organisations and leadership within each doctor's daily practice. Text analysis shows that the first two perspectives refer to medical leadership mainly in a defensive manner: by demonstrating medical leadership doctors could 'take the lead' once again; patient care only seems to play a small part in the process. These perspectives are not free of consequences, they will determine how the medical profession is constructed. For this reason, it is argued that there should be more emphasis on the third perspective, in which the quality of care for patients is of primary importance.

    2009-01-01

    Full Text Available The effect of an electric field on the antibacterial activity of columnar aligned silver nanorods was investigated. Silver nanorods with a polygonal cross section, a width of 20–60 nm and a length of 260–550 nm, were grown on a titanium interlayer by applying an electric field perpendicular to the surface of a Ag/Ti/Si(100 thin film during its heat treatment at 700 °C in an Ar+H2 environment. The optical absorption spectrum of the silver nanorods exhibited two peaks at wavelengths of 350 and 395 nm corresponding to the main surface plasmon resonance bands of the one-dimensional silver nanostructures. It was found that the silver nanorods with an fcc structure were bounded mainly by {100} facets. The antibacterial activity of the silver nanorods against Escherichia coli bacteria was evaluated at various electric fields applied in the direction of the nanorods without any electrical connection between the nanorods and the capacitor plates producing the electric field. Increasing the electric field from 0 to 50 V cm−1 resulted in an exponential increase in the relative rate of reduction of the bacteria from 3.9×10−2 to 10.5×10−2 min−1. This indicates that the antibacterial activity of silver nanorods can be enhanced by applying an electric field, for application in medical and food-preserving fields.

    The conversion of heat energy into electrical energy by a small compact device is descrtbed. Where the heat energy is supplied by a radioactive material and thermopIIes convert the heat to electrical energy. The particular battery construction includes two insulating discs with conductive rods disposed between them to form a circular cage. In the center of the cage is disposed a cup in which the sealed radioactive source is located. Each thermopile is formed by connecting wires from two adjacent rods to a potnt on an annular ring fastened to the outside of the cup, the ring having insulation on its surface to prevent electrica1 contact with the thermopiles. One advantage of this battery construction is that the radioactive source may be inserted after the device is fabricated, reducing the radiation hazard to personnel assembling the battery.

Optical metamaterials, in particular, are less compatible with active functionalities than their counterparts developed at lower frequencies. One crucial roadblock in the path to devices is the fact that active optical metamaterials are so far controlled by light rather than electricity, preventing them from being integrated in larger electronic systems. Here we introduce electroluminescent metamaterials based on metal nano-inclusions hybridized with colloidal quantum dots. We show that each of these miniature blocks can be individually tuned to exhibit independent optoelectronic properties (both in terms of electrical characteristics, polarization, colour and brightness), illustrate their capabilities by weaving complex light-emitting surfaces and finally discuss their potential for displays and sensors.

  14. Pulsed plasmoid electric propulsion

    Bourque, Robert F.; Parks, Paul B.; Tamano, Teruo

    1990-01-01

    A method of electric propulsion is explored where plasmoids such as spheromaks and field reversed configurations (FRC) are formed and then allowed to expand down a diverging conducting shell. The plasmoids contain a toroidal electric current that provides both heating and a confining magnetic field. They are free to translate because there are no externally supplied magnetic fields that would restrict motion. Image currents in the diverging conducting shell keep the plasmoids from contacting the wall. Because these currents translate relative to the wall, losses due to magnetic flux diffusion into the wall are minimized. During the expansion of the plasma in the diverging cone, both the inductive and thermal plasma energy are converted to directed kinetic energy producing thrust. Specific impulses can be in the 4000 to 20000 sec range with thrusts from 0.1 to 1000 Newtons, depending on available power.

    Metamaterials bring sub-wavelength resonating structures together to overcome the limitations of conventional matter. The realization of active metadevices has been an outstanding challenge that requires electrically reconfigurable components operating over a broad spectrum with a wide dynamic range. The existing capability of metamaterials, however, is not sufficient to realize this goal. Here, integrating passive metamaterials with active graphene devices, we demonstrated a new class of electrically controlled metadevices. These metadevices enable efficient control of both amplitude (>50 dB) and phase (>90 deg.) of electromagnetic waves. In this hybrid system, graphene operates a tunable Drude metal that controls the radiation of the passive metamaterials. Furthermore, by integrating individually addressable arrays of metadevices, we demonstrated a new class of spatially varying digital metasurfaces where the local dielectric constant can be reconfigured with a bias voltage. Our approach is general enough t...

  17. Electrical properties of materials

    CERN Document Server

    Solymar, L; Syms, R R A

    2014-01-01

    An informal and highly accessible writing style, a simple treatment of mathematics, and clear guide to applications have made this book a classic text in electrical and electronic engineering. Students will find it both readable and comprehensive. The fundamental ideas relevant to the understanding of the electrical properties of materials are emphasized; in addition, topics are selected in order to explain the operation of devices having applications (or possible future applications) in engineering. The mathematics, kept deliberately to a minimum, is well within the grasp of a second-year student. This is achieved by choosing the simplest model that can display the essential properties of a phenomenom, and then examining the difference between the ideal and the actual behaviour. The whole text is designed as an undergraduate course. However most individual sections are self contained and can be used as background reading in graduate courses, and for interested persons who want to explore advances in microele...

  18. Gut feeling is electric

    Familoni, Jide

    2011-06-01

    Although "gut feeling" is a cliché in English parlance, there are neuro-physiological basis for registration of emotions in the gut. Control of the gastro-intestinal (GI) tract is by an integration of neuro-hormonal factors from the local myogenic to the central nervous system. Gastric contractile activity, which is responsible for the motor properties of the stomach, is regulated by this integrated complex. Signatures of the activity include gastric electrical activity (GEA) and bowel sounds. GEA has two distinct components: a high-frequency spike activity or post depolarization potential termed the electrical response activity superimposed on a lower frequency, rhythmic depolarization termed the control activity. These signatures are measured in the clinic with contact sensors and well understood for diagnosis of gut dysmotility. Can these signatures be measured at standoff and employed for purposes of biometrics, malintent and wellness assessment?

We find that there exists a competitive market segment where a number of retailers compete fiercely for customers, with small margins on all products. However, we also find evidence of monopolistic behaviour, whereby retailers exploit the passivity of some of their customers. We discuss explanations for these results, as well as means to im...

  8. Reliability impact of solar electric generation upon electric utility systems

    Day, J. T.; Hobbs, W. J.

    1982-08-01

    The introduction of solar electric systems into an electric utility grid brings new considerations in the assessment of the utility's power supply reliability. This paper summarizes a methodology for estimating the reliability impact of solar electric technologies upon electric utilities for value assessment and planning purposes. Utility expansion and operating impacts are considered. Sample results from photovoltaic analysis show that solar electric plants can increase the reliable load-carrying capability of a utility system. However, the load-carrying capability of the incremental power tends to decrease, particularly at significant capacity penetration levels. Other factors influencing reliability impact are identified.

  9. Electric-vehicle batteries

    Oman, Henry; Gross, Sid

    1995-02-01

    Electric vehicles that can't reach trolley wires need batteries. In the early 1900's electric cars disappeared when owners found that replacing the car's worn-out lead-acid battery costs more than a new gasoline-powered car. Most of today's electric cars are still propelled by lead-acid batteries. General Motors in their prototype Impact, for example, used starting-lighting-ignition batteries, which deliver lots of power for demonstrations, but have a life of less than 100 deep discharges. Now promising alternative technology has challenged the world-wide lead miners, refiners, and battery makers into forming a consortium that sponsors research into making better lead-acid batteries. Horizon's new bipolar battery delivered 50 watt-hours per kg (Wh/kg), compared with 20 for ordinary transport-vehicle batteries. The alternatives are delivering from 80 Wh/kg (nickel-metal hydride) up to 200 Wh/kg (zinc-bromine). A Fiat Panda traveled 260 km on a single charge of its zinc-bromine battery. A German 3.5-ton postal truck traveled 300 km with a single charge in its 650-kg (146 Wh/kg) zinc-air battery. Its top speed was 110 km per hour.

    Generazio, Ed

    2017-01-01

    The technology and methods for remote quantitative imaging of electrostatic potentials and electrostatic fields in and around objects and in free space is presented. Electric field imaging (EFI) technology may be applied to characterize intrinsic or existing electric potentials and electric fields, or an externally generated electrostatic field may be used for illuminating volumes to be inspected with EFI. The baseline sensor technology (e-Sensor) and its construction, optional electric field generation (quasi-static generator), and current e- Sensor enhancements (ephemeral e-Sensor) are discussed. Critical design elements of current linear and real-time two-dimensional (2D) measurement systems are highlighted, and the development of a three dimensional (3D) EFI system is presented. Demonstrations for structural, electronic, human, and memory applications are shown. Recent work demonstrates that phonons may be used to create and annihilate electric dipoles within structures. Phonon induced dipoles are ephemeral and their polarization, strength, and location may be quantitatively characterized by EFI providing a new subsurface Phonon-EFI imaging technology. Initial results from real-time imaging of combustion and ion flow, and their measurement complications, will be discussed. These new EFI capabilities are demonstrated to characterize electric charge distribution creating a new field of study embracing areas of interest including electrostatic discharge (ESD) mitigation, crime scene forensics, design and materials selection for advanced sensors, combustion science, on-orbit space potential, container inspection, remote characterization of electronic circuits and level of activation, dielectric morphology of structures, tether integrity, organic molecular memory, atmospheric science, and medical diagnostic and treatment efficacy applications such as cardiac polarization wave propagation and electromyography imaging.

    In urban area, due to their beneficial effect on environment, electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are an important factor for improvement of traffic and more particular for a healthier environment. Moreover, the need for alternative energy source is growing and the price competition of alternatives against oil is becoming more and more realistic. Electric vehicles, hybrid electric vehicles and fuel cell electric vehicles are offering the best possibility for the use of new energy sources, because electricity can result from a transformation with high efficiency of these sources and is always used with the highest possible efficiency in systems with electric drives or components. Some basic considerations about the situation today and in a mid and long-term perspective, are presented together with the infrastructure developments.

  6. Topics on electricity trade

    Energy Technology Data Exchange (ETDEWEB)

    Skytte, K.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

  7. Medical education in Malaysia.

    Lim, Victor K E

    2008-01-01

    Malaysia has a long history of medical education, with Singapore becoming the first medical school to serve the region after its foundation in 1905. The first school to be established in Kuala Lumpur after independence from the British was the Faculty of Medicine at the University of Malaya in 1963. Whilst today there are 21 public and private medical schools, all offering a 5 year undergraduate programme, some private schools have diversified by developing international collaboration and conduct twinning or credit-transfer programmes. All medical schools require accreditation by the National Accreditation Board and the Malaysian Medical Council. Although the criteria for accreditation is comprehensive and covers a broad range of areas of assessment, it is debatable whether it always matches the needs of the country. The dramatic increase in medical schools in the last two decades has posed challenges in terms of maintenance of quality, physical infrastructure and suitably qualified faculty.

    The term 'medical tourism' is under debate because health care is a serious business and rarely do patients combine the two. India is uniquely placed by virtue of its skilled manpower, common language, diverse medical conditions that doctors deal with, the volume of patients, and a large nonresident Indian population overseas. Medical tourism requires dedicated services to alleviate the anxiety of foreign patients. These include translation, currency conversion, travel, visa, posttreatment care system,and accommodation of patient relatives during and after treatment.

    Far from being a purely modern idea, the notion of “electric music” was already common in the eighteenth and nineteenth centuries. The shift in thinking about music from cosmic harmony to nervous stimulation made metaphors and speculative theories relating music and electricity irresistible. This essay considers the development of the idea of electric music, looking at its associations with a sexual “body electric.” It will then examine how this conception of music went from being the subject of sympathy to becoming part of a medical critique of music as a dangerous stimulant, with echoes in music criticism and beyond.

    Medical training is challenging and parenting is a full-time responsibility. Balancing a family with the significant demands of medical school is a daunting endeavor. Yet there is little research available to guide students, faculty, or administrators. Using one U.S. medical school as a case study, this article provides a comprehensive overview of the common personal and professional challenges that medical students who are also mothers face during their undergraduate medical education, and practical strategies and resources useful in navigating such challenges. This article is also a resource guide for the faculty and administrators who teach, advise, and mentor medical-student parents. For leaders in medical education, the article concludes with suggestions to better support the health and educational experience of medical student-parents: 1) a systematic network of career advisors, 2) scheduling flexibility, 3) formal breastfeeding policies and workplace support, 4) institutionally supported childcare, and 5) how student-parents may foster the educational health mission of medical schools.

  19. Cannabinoids: Medical implications.

    Herbal cannabis has been used for thousands of years for medical purposes. With elucidation of the chemical structures of tetrahydrocannabinol (THC) and cannabidiol (CBD) and with discovery of the human endocannabinoid system, the medical usefulness of cannabinoids has been more intensively explored. While more randomized clinical trials are needed for some medical conditions, other medical disorders, like chronic cancer and neuropathic pain and certain symptoms of multiple sclerosis, have substantial evidence supporting cannabinoid efficacy. While herbal cannabis has not met rigorous FDA standards for medical approval, specific well-characterized cannabinoids have met those standards. Where medical cannabis is legal, patients typically see a physician who "certifies" that a benefit may result. Physicians must consider important patient selection criteria such as failure of standard medical treatment for a debilitating medical disorder. Medical cannabis patients must be informed about potential adverse effects, such as acute impairment of memory, coordination and judgment, and possible chronic effects, such as cannabis use disorder, cognitive impairment, and chronic bronchitis. In addition, social dysfunction may result at work/school, and there is increased possibility of motor vehicle accidents. Novel ways to manipulate the endocannbinoid system are being explored to maximize benefits of cannabinoid therapy and lessen possible harmful effects.

    The provision of electricity has been a great benefit to society, particularly in health terms, but it also carries health costs. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows the health burdens to be greatest for power stations that most pollute outdoor air (those based on lignite, coal, and oil). The health burdens are appreciably smaller for generation from natural gas, and lower still for nuclear power. This same ranking also applies in terms of greenhouse-gas emissions and thus, potentially, to long-term health, social, and economic effects arising from climate change. Nuclear power remains controversial, however, because of public concern about storage of nuclear waste, the potential for catastrophic accident or terrorist attack, and the diversion of fissionable material for weapons production. Health risks are smaller for nuclear fusion, but commercial exploitation will not be achieved in time to help the crucial near-term reduction in greenhouse-gas emissions. The negative effects on health of electricity generation from renewable sources have not been assessed as fully as those from conventional sources, but for solar, wind, and wave power, such effects seem to be small; those of biofuels depend on the type of fuel and the mode of combustion. Carbon dioxide (CO2) capture and storage is increasingly being considered for reduction of CO2 emissions from fossil fuel plants, but the health effects associated with this technology are largely unquantified and probably mixed: efficiency losses mean greater consumption of the primary fuel and accompanying increases in some waste products. This paper reviews the state of knowledge regarding the health effects of different methods of generating electricity.

    In this paper, we present an analysis and modeling of the electrical diffusion equation using the fractional calculus approach. This alternative representation for the current density is expressed in terms of the Caputo derivatives, the order for the space domain is 0numerical methods based on Fourier variable separation. The case with spatial fractional derivatives leads to Levy flight type phenomena, while the time fractional equation is related to sub- or super diffusion. We show that the mathematical concept of fractional derivatives can be useful to understand the behavior of semiconductors, the design of solar panels, electrochemical phenomena and the description of anomalous complex processes.

    In this book a general matrix-based approach to modeling electrical machines is promulgated. The model uses instantaneous quantities for key variables and enables the user to easily take into account associations between rotating machines and static converters (such as in variable speed drives).   General equations of electromechanical energy conversion are established early in the treatment of the topic and then applied to synchronous, induction and DC machines. The primary characteristics of these machines are established for steady state behavior as well as for variable speed scenarios. I

    We study the role of vertical structure in determining generating capacities and retail prices in the electricity industry. Allowing for uncertain demand, we compare three market configurations: (i) integrated monopoly, (ii) integrated duopoly with wholesale trade, and (iii) separated duopoly...... with wholesale trade. We find that equilibrium capacities and retail prices are such that welfare is highest (lowest) under separated (integrated) duopoly. The driving force behind this result is the risk of rent extraction faced by competing integrated generators on the wholesale market. Our analysis suggests...
