    This compendium on Togo contains a summary of current and projected demographic indicators, of government population policies and attitudes, and of the current status of the country's population data collecting system. The information is further summarized in a 1-page fact sheet. In 1981 the total population was 2.7 million. In 1980-85, the annual population growth rate was 2.9%, and the annual natural increase rate was 2.9%, life expectancy at birth was 48.7 years, the infant mortality rate was 113, and the crude birth rate was 45.4. Per capita income was US$406 in 1979, and in 1981, 67% of the labor force was engaged in agriculture. Currently the government has no policies in regard to population growth and is satisfied with the current fertility level. Earlier the government's position was pronatalist; but, in 1976, the government approved the establishment of the Togolese Family Welfare Association (ATBEF), an affiliate of the International Planned Parenthood Federation. In addition, the government is promoting the integration of family planning services in the nation's primary health program. The government is concerned with the problem of teenage pregnancy. Abortion, except to save the life of the mother, is illegal, and there are no legal provisions concerning sterilization. In recent years, the government adopted several measures aimed at improving the status of women. These measures included the passage of a new family code. The major concerns of the government are to improve the health status of the population and to promote rural and regional development. The primary health care program was expanded in 1977, and the country has a fairly successful immunization program. It also operates a leprosy control program and is improving the country's water supply. Currently the level of international migration, both emigration and immigration, is low, and the government has no migration policy. Togo has a low urban rate (17.4%), and between 1970-80, the rate of

    the isolated center, volume capture-and-store software is used. Later on, the UHC expert uses Echo-Cnes 3D software to reconstruct the organs scanned. The expert can then navigate within the reconstructed volume and display any plane. Volume capture is performed by tilting (± 40°) to both sides vertically to the skin. To locate the probe on the organ acoustic window, the novice operator uses acoustic window mapping designed by our laboratory (UMPS-Tours). The system was tested between the Tsévié regional hospital in Togo (40 km from Lomé, Togo, and 4500 km from Tours, France) and the UHC at Lomé and the Trousseau UHC in Tours. With an average internet connection of 2 Mbps, the quality of transmission of the background video and ultrasound sequence videos from Tsévié towards Lomé was satisfactory (16 images/s) with a maximal transmission delay of 1.5 s (almost in real time). A video conference between the Trousseau UHC in Tours, the UHC Campus in Lomé and the Tsévié Hospital was possible and the bandwidth allowed the Lomé experts (radiologists) to perform real-time telesonography with very satisfactory results (ultrasound diagnoses obtained) for abdominal (n = 5), pelvic (n = 3), obstetric (n = 2), prostate (n = 2) and mammary (n = 2) ultrasound, both normal and pathological. Because the doctors at Tsévié had minimal experience with ultrasound, complete ultrasound diagnoses were obtained by combining remote voice instruction for image capture and full diagnosis by Echo-Cnes. Asynchronous telediagnosis was also performed with Tsévié operators who lacked ultrasound expertise but could perform the required tilt movements (after 3 training sessions). The expert at Trousseau UHC performed real-time telesonography with the Tsévié Hospital for two cases requiring abdominal images and another viewing of the prostate. He also performed asynchronous reconstruction of the abdominal organs with Echo-Cnes. A demonstration seminar of our platform was organized

    Full Text Available In this paper, we describe a server/client literature management system specialized for the life science domain, the TogoDoc system (Togo, pronounced Toe-Go, is a romanization of a Japanese word for integration. The server and the client program cooperate closely over the Internet to provide life scientists with an effective literature recommendation service and efficient literature management. The content-based and personalized literature recommendation helps researchers to isolate interesting papers from the "tsunami" of literature, in which, on average, more than one biomedical paper is added to MEDLINE every minute. Because researchers these days need to cover updates of much wider topics to generate hypotheses using massive datasets obtained from public databases or omics experiments, the importance of having an effective literature recommendation service is rising. The automatic recommendation is based on the content of personal literature libraries of electronic PDF papers. The client program automatically analyzes these files, which are sometimes deeply buried in storage disks of researchers' personal computers. Just saving PDF papers to the designated folders makes the client program automatically analyze and retrieve metadata, rename file names, synchronize the data to the server, and receive the recommendation lists of newly published papers, thus accomplishing effortless literature management. In addition, the tag suggestion and associative search functions are provided for easy classification of and access to past papers (researchers who read many papers sometimes only vaguely remember or completely forget what they read in the past.

    Development has been made on the element technologies for a home rehabilitation system for aphasia patients. First, studies were performed on an authoring procedure for aphasia patient training, and partial trial production and development were carried out on an authoring system for the training program formula. Then, studies were executed on a training simulation and analysis filter, and partial trial production and development were implemented on a home rehabilitation supporting and self-teaching system. Next, an input and output mechanism for voice signal processing was studied, and aphasia patient and caregiver human interface was partially fabricated on a trial basis. In addition, a remote rehabilitation communicating method was researched, and partial trial production was carried out on a remote rehabilitation evaluation and diagnosis support means. Finally, communication assisting means were researched, and a communication assisting system was partially produced on a trial basis. Good evaluation results were given on a demonstration system. Although partial indications were given on minute parts, practical agreement was obtained as a whole. Great expectation was given particularly on the remote rehabilitation system and the authoring system. (NEDO)

    TogoTable (http://togotable.dbcls.jp/) is a web tool that adds user-specified annotations to a table that a user uploads. Annotations are drawn from several biological databases that use the Resource Description Framework (RDF) data model. TogoTable uses database identifiers (IDs) in the table as a query key for searching. RDF data, which form a network called Linked Open Data (LOD), can be searched from SPARQL endpoints using a SPARQL query language. Because TogoTable uses RDF, it can integrate annotations from not only the reference database to which the IDs originally belong, but also externally linked databases via the LOD network. For example, annotations in the Protein Data Bank can be retrieved using GeneID through links provided by the UniProt RDF. Because RDF has been standardized by the World Wide Web Consortium, any database with annotations based on the RDF data model can be easily incorporated into this tool. We believe that TogoTable is a valuable Web tool, particularly for experimental biologists who need to process huge amounts of data such as high-throughput experimental output. © The Author(s) 2014.

    This paper reports the current research result of the field work information support system in a one-stop service system. The work arrangement in the branch office of an electric company is how to assign the service operator efficiently and accurately for the transfer to the customer. This problem is grasped as a traveling salesman problem (TSP) of `make the round of `n` works by `m` persons for processing and return to the branch office with the branch office as a start point`. The system in which the day`s schedule of each operator can be automatically created by entering only the work schedule (including limitation conditions (difficulty degree of work contents or time appointment) and skill management information of each work) was investigated. The compatibility and evaluation of each traveling route search method were carried out. As a result, the genetic algorithm is judged to be fully practical. The communication information for field work could be retrieved in real time using PHS. This system can also be applied to the maintenance or consulting including a disaster or accident as well as general work. 4 figs., 1 tab.

    In order to improve the existing design-supporting system for offshore structures, new functions are added to evaluate information of the products, especially those for structural designs. The structural analysis system should be provided with a function of design modification, to efficiently support the structural analysis of these structures. The new system adds hierarchy of various offshore structure models and three-dimensional dimensions to clarify structural and geometrical constraints and design-modification function. The design-modification function is included by use of the hierarchy. The other new functions are finite element analysis systems for the main structure and components, and rigidity calculation for the main structure. The main structure and functional element models are confirmed to be useful also for utilization of information, and provide necessary information of the product models. 11 refs., 11 figs.

    It is only since the independance of Togo, in 1958, and after 3 General Census, (1958-59, 1970, 1981), followed immediately by post-census surveys, that a solid basis of statistical data has been available for demographic research. But it is only after 1970, with the creation of the Benin University, and its Demographic Research Unit, the arrival of researchers at the ORSTOM Center of Lome, and of the demographers trained at the IFORD and IDP, that real demographic research has existed. Since then, the ORSTOM has conducted a study on the dynamics of population (fertility, migration, nuptiality, mortality) and its socioeconomic consequences on the agricultural economy of the Plateau Region (1975-1979). It is currently conducting a study in North Togo, comparing demographic data (nuptiality, fertility, infant mortality, family structure) with socioeconomic data (system of land property, women's activity, wives' status in polygamic families), for a better understanding of the influence of demographic reproduction on global social reproduction. The Demographic Research Unit led several studies on fertility in Southeast Togo and Lome. Several other surveys by the department of statistics and the IFORD, by the INRS, as well as student these from diverse schools of Benin University, are studying demo-geography, demo-economy, and demo-sociology. Still, the main problems are the bad quality of the data on fertility and mortality, and the inconsistancy of civil registration. But the interest of the present administration for demographic information may lead to the creation of a "Population Unit" assisting the government, to the definition of a status for researchers, and to the participation of Togo in the new program of Demographic and Health Surveys planned for 35 countries by the Westinghouse Institute for Resource Development.

    The losses of K by leaching below the root zone were almost compensated by rainfall inputs. The main output of K under traditional management was the removal of crop residues. The soil fixes and releases K, probably on the small quantity of interstratified clay minerals. Fixation decreases the availability of K fertilizer by about 15%. Release can explain why crop yields are poorly correlated to exchangeable K in depleted soil. The occurrence of interstratified clay minerals in tropical soils suggests that K fixation and release could be widespread. In the Ferralsols of Togo, K fertilization should compensate removals, with an additional 15% to balance fixation. The quantity of K required to ensure sustainability depends on the fate of residues. The present system of residue removal without fertilization is leading to a drastic reduction of soil K. (authors). 4 refs., 1 fig., 1 tab.

    The extent of medicines sales and consumption in the informal market in Togo raises many ethical and public health issues. In order to report on the situation of public action in the fight against this practice, we conducted a qualitative survey from 15 to 25 February 2016 in the commune of Lomé and in the Maritime Region among the actors of control system and resource people in the general population. This was supplemented by an analysis of Togo's pharmaceutical and health policy documents and a literature review on the illicit drug market issues relating to public health, political science, the social sciences applied to health. In spite of the existence of national and international tools, household poverty, cultural self-medication, ignorance of the population concerning the health risks of informal market medicines, weak political commitment, weakness regulation and enforcement, corruption, constitute obstacles to the success of actions to combat this practice.

    In Togo, as in many other developing countries, there is a lack of data on quality control and assurance of laboratories. The present study aimed to access for the quality management system in five medical bacteriology laboratories in Togo. The study was conducted from May to August 2006. Data were recorded by an audit on the reliability of results and the technical organization of laboratories. The standard ISO 15189:2003, the Togolese guide of good laboratory practices (GBEA-Togo) and the WHO medical bacteriology standards were used as references. The results of the audit showed a lack of culture media in laboratories, inappropriate choice of culture media, partial identification of some microorganisms, variability of identification procedures, a lack of diagnostic reagents and an inability to identify some potentially pathogenic bacteria. Concerning the technical organization of laboratories, compliance average ranging from 25.8 to 54.8 % was recorded. This indicates a limited organization of such laboratories. The issue of this study showed that laboratories must be equipped, their technical organization should be improved and they must establish a program of equipment maintenance.

    Full Text Available Willingness to Pay for Biopesticides: A Survey of Vegetables Producers in the South Coast of Togo. The actual study assessed the willingness to pay for biopesticides by vegetables producers in coastal Togo as more sustainable alternatives than chemical pesticides. Through contingent valuation, it appeared that for purchasing biopesticides, producers are willing to pay a premium of 18-20% base on the price of Decis, the chemical pesticides among the most expensive and the most used in coastal vegetable production in Togo. The Tobit model revealed that among factors affecting vegetables producers' decision making process, information and the farm size play a crucial role. Given the low level of the premium that vegetables producers are willing to pay and the current characteristics of the farm, the introduction of biopesticides within their cropping system, could lead to mitigated success in the absence of an appropriate incentive framework.

    To verify the clean coal technology to be diffused in China and consolidate its diffusion basis, demonstration project of circulating fluidized bed boiler was conducted through the cooperation with China which is positive in its introduction. This report describes its characteristics. Coal and limestone are supplied in a lower part of combustion chamber, and are mixed with circulating ash by fluidized air for combustion. Densely fluidized bed the same as the bubbling fluidized bed is formed in the lower part of combustion chamber, which provides excellent stability in ignition and combustion. Particles including ash, char and limestone formed during the combustion are discharged into the cyclone through the convection heat transfer part at the outlet of combustion chamber with the combustion gas flow. Since the gas temperature is lowered to 400 to 500degC at the convection heat transfer part, troubles of the ash circulating system can be prevented. The combustion gas separated from ash at the cyclone is discharged through the heat exchanger and precipitator, and the collected ash is returned to the lower part of combustion chamber. In FY 1997, design, fabrication, procurement/inspection, field survey/meeting, survey of visitors/meeting, and education were carried out. 4 figs., 4 tabs.

  20. The Vitality of Kabiye in Togo Zur Überlebensfähigkeit des Kabiye in Togo

    Directory of Open Access Journals (Sweden)

    Komlan Essowe Essizewa

    2009-01-01

    Full Text Available In Togo, speakers of Kabiye have been in contact with the speak¬ers of Ewe for several decades due to migration. As a result of this language contact, many members of the Kabiye speech community have become bilingual in Kabiye and Ewe. There have been a number of claims that Kabiye “est une langue en péril” (Aritiba 1993: 11. These claims have been based mainly on the observation of Kabiye speakers in Lomé and other major cities, where younger speakers seem to be losing their mother tongue to the benefit of Ewe. However, the extent of the loss of Kabiye is not well known because no extensive sociolinguistic study has been carried out among Kabiye speakers in these areas, and more specifically, in major Kabiye-speaking areas. The current study which has been carried out in Kara, the major Kabiye-speaking city and Awidina, a Kabiye village of the prefecture of Kara, fills the gap. The paper examines Kabiye speakers’ reports of patterns of language use in these areas of the Kabiye community. Seit einigen Jahrzehnten leben Kabiye-sprachige Migranten in Togo in Kontakt mit der Ewe-sprachigen Bevölkerung. Im Ergebnis dieses Sprachkontakts sind viele Angehörige der Kabiye-Sprachgemeinde bilingual und kombinieren Kabiye und Ewe. Kabiye wird inzwischen vielfach als sterbende Sprache angesehen. Diese Einschätzungen beruhen aber vor allem auf der Beobachtung von Kabiye-Sprachigen in Lomé und anderen großen Städten, wo die jungen Leute nach und nach ihre Muttersprache zugunsten von Ewe aufgeben. Dennoch ist über das Ausmaß des Verschwindens von Kabiye wenig bekannt, denn bislang gibt es keine extensive Studie unter Kabiye-Sprachigen in diesen Gebieten, insbesondere aber auch keine für Regionen, in denen Kabiye die wichtigste Sprache darstellt. Die vorliegende Studie, die in Kara, der wichtigsten Kabiye-sprachigen Stadt, und in Awidina, einem Kabiye-Dorf in der Präfektur Kara, durchgeführt wurde, will diese Lücke schließen. Der Autor

    We report the successive stages of the reorganization of the blood transfusion sector in Togo. The starting point was the elaboration of the national policy of blood transfusion, then the adoption of a decree organizing the sector as well the various decree of application, particularly that related to transfusion good practices. The current policy recommends two poles of qualification of the blood ant its components and the creation of six stations of collection and distribution attached to these poles. The reorganization started with the rehabilitation of the National Blood Transfusion Centre (CNTS) in Lomé. If the problem of human resources is alarming, especially the availability of hemobiologists, the rehabilitation allowed the increase of the blood collection passing from 5272 donations in December 2003 to 18 164 in December 2008. However, the requirement of blood products is satisfied in 50% in all the country. In 2003, 24% of the blood products were rejected for positive viral markers against 8.37% in 2008 in relation with the improvement of blood safety. Efforts must be continued to reinforce it in the CNTS and to make a better selection of the donors at the Regional Blood Transfusion Centre (CRTS) de Sokodé. The analysis of the weak points of the sector (human resource insufficiency, shortage of the blood products, blood safety) made it possible to indicate solutions to improve the sector of blood transfusion sector. Future outcome is funded in the blood transfusion safety development project in Togo financed by the Agence française de développement (AFD, French development agency).

    The spine is a frequent site of infection but cervical spine localization seems to be rare. to determine the frequency and features of cervical spondylodiscitis in patients attending the Sylvanus Olympio University Hospital Center in Togo. A retrospective study of patients hospitalized in the Department of Rheumatology over a 20-year period was conducted. The positive diagnosis of infectious spondylodiscitis has been clinical and radiological. The etiological presumption was founded on clinical and epidemiological arguments. Of the 2881 patients hospitalized, 356 had infectious spondylodiscitis of which 15 cases of cervical spondylodiscitis (eight men and seven women). The average age of these 15 patients was 37 years at the onset of the disease of which the mean disease duration was six months. The disease was essentially located at the levels of C3C4 (seven patients) and C5C6 (four patients). Spondylodiscitis was related to presumptive tuberculosis in 10 patients and banal germ in the remaining five others. There were three HIV infected patients. The onset of the symptomatology was progressive in all the 10 patients suffering from tuberculosis spondylodiscitis. The symptomatology has been characterized by inflammatory pains (10 patients), mechanic pains (five patients), and a gibbosity (four patients). This study attests of the scarcity of the cervical spondylodiscitis.

    In order to master the difficulties due to sickle cell disease, this work aimed at assessing the effects on the families of the presence of a child with sickle cell disease in Togo. From April 1 to November 31, 1998, 103 families with one or many sickle cell patients followed up in the Sickle Cell Care Unit of the pediatric department of the Lome Teaching Hospital were surveyed. Main care takers of patients with sickle cell disease, especially mothers (90.3% of cases), were surveyed. Many parents were disturbed; the most common troubles were: compassion (pity) toward the child, 92.2%; insomnia, 82.5%; frustration, 76.7%; and fear of the death of the child, 73.5%. Less educated parents and those who lived alone (single parents, widows, separated) were more affected. Sickle cell disease caused the separation of seven couples out of 26 (26.9%), while in 11 couples of the 63 who still live together, relationships had deteriorated (17.5%). Most of the parents (83.3%) exaggerated the protection of their child and 65% mentioned financial problems. There is no doubt about the unfortunate effects of the presence of children with sickle cell disease in a family in Lome. Many joint actions should be taken toward the sick children and their families in order to reduce their sufferings.

    Tuberculosis (TB) remains one of the most lethal communicable diseases in the world, according to the World Health Organization (WHO). New strategies must be implemented to meet targets for 2035. Describe the epidemiological and therapeutic aspects of tuberculosis in children in Togo. This retrospective, multicenter, descriptive cross-sectional study examined the files of children younger than 15 years who were diagnosed with TB and treatment in the Maritime region from 2008 to 2011. The study included 74 children aged 0-15 years, for an average of 18 cases of childhood tuberculosis annually. Pulmonary tuberculosis (38 cases) was the most common. TB-HIV co-infection was found in 14.9% of cases. Boys accounted for more than half of the patients. The age range of 11-15 years accounted for the highest proportion of cases (41.9%). The most common treatment was a combination of 2RHZE and 4RH (25 children, 33.8%). Laboratory monitoring was satisfactory. In all, 56 (75.7%) children were cured, and 14 (18.2%) lost to follow-up, while 3 (4%) died (all with TB/HIV). Active testing for HIV infection is essential in children with TB, because the combination of the two can be lethal.

    The purpose is to develop fundamental technologies for navigation systems and mobile computing systems in museums, theme parks and cities. Concretely, we implement software agents into the mobile computing environment which consists of PHS, mobile computers and mobile robots, and realize various functions to access regional information. We have studied on Communityware which supports human activities and communities by using mobile agents implemented into mobile computers and town robots. The mobile agents, which intelligently process information obtained in physical and virtual worlds, access regional information which is omnipresent in the environment. With respect to the approach using mobile computers, we have provided one hundred mobile computers in the international conference on multiagent systems 1996 and carried out the first experimentation of mobile computing in the world. The mobile computer has two functions: Community Viewer which displays interactions between members of communities and Social Matchmaker which supports to hold meetings by searching for people who have common interests. With respect to the approach using town robots, we have developed a robot system which can robustly behave in a complex outdoor environment by using vision agents embedded in the environment. The system aims at support of people in streets. (NEDO)

    A survey was conducted in Togo in March-April 1995 by the Demographic Research Unit of the University of Benin, Lome, as an extension of a fertility survey conducted in 1976. The 1976 survey showed a high demand for children, with fertility rates of nearly 6.5 per woman. The present survey was undertaken to assess the effects of the economic crisis suffered in Togo since the 1980s on fertility and women's status. Survey questions related to land access, women's income from agriculture and trade, matrimonial status, and family solidarity. Survey results should indicate whether a "crisis demographic transition" has taken place due to economic factors. Information on survey results can be obtained by writing to the Demographic Research Unit of the University of Benin, Lome, P. O. Box 12971, Lome, Togo.

Community health workers (CHWs became involved in 2007. In 2010, the impact of the implementation of these new malaria control strategies had not yet been evaluated. This study sought to assess the trends of malaria incidence and mortality due to malaria in Est Mono district from 2005 to 2010. Methods Secondary data on confirmed and suspected malaria cases reported by health facilities from 2005 to 2010 were obtained from the district health information system. Rainfall and temperature data were provided by the national Department of Meteorology. Chi square test or independent student’s t-test were used to compare trends of variables at a 95% confidence interval. An interrupted time series analysis was performed to assess the effect of meteorological factors and the use of ACT and CHWs on morbidity and mortality due to malaria. Results From January 2005 to December 2010, 114,654 malaria cases (annual mean 19,109 ± 6,622 were reported with an increase of all malaria cases from 10,299 in 2005 to 26,678 cases in 2010 (p Conclusion This study showed an increase of malaria prevalence despite the implementation of the use of ACT and CHW strategies. Multicentre data analysis over longer periods should be carried out in similar settings to assess the impact of malaria control strategies on the burden of the disease. Integrated malaria vector control management should be implemented in Togo to reduce malaria transmission.

    2000-11-01

    One of the major problems of epilepsy in Africa are its social implications. Prejudice against the disease is common and epileptics are marginalised. Epilepsy is concealed from all non-family members. The very pronunciation of the word "falling disease" (as epilepsy is called) is taboo, the disease being regarded as supernatural. This unfavourable context introduces considerable bias in hospital and population-based studies. Traditional doctors are consulted by patients especially when they have such a "supernatural" disease. Traditional scarifications are used for the treatment of epileptics in Togo. We examined the skin of 36,000 patients in the neurological department of Lomé's teaching hospital between 1985 and 1995 and conducted a similar, population-based study on about 20,000 inhabitants in the Kloto district of south-western Togo and on 10,000 inhabitants in the Tone district of northern Togo. Interviews with 40,000 traditional doctors revealed that forehead scarifications are characteristic of epilepsy treatment. More than 80% of epileptics have forehead scarifications. When the seizures are rare, scarifications are slim, short (1-3 mm), near the roots of hair on the forehead and concealed; but when they are frequent, known by many people, scarifications are large, long, visible on forehead, the patient showing the sign of his social sentence.. On the skin of epileptics in Togo, is written the diagnosis of his affection. It only needs to look at it.

    Incompleteness of vaccination coverage among children is a major public health concern because itcontinues to sustain a high prevalence of vaccine-preventable diseases in some countries. In Togo, very few data on the factors associated with incomplete vaccination coverage among children have been published. We determined the prevalence of incomplete immunization coverage in children aged one to five years in Togo and associated factors. This was a cross-sectional study using secondary data from the 2010 Multiple Indicator Cluster Surveys (MICS4) conducted in 2010 among children aged 1 to 5 years in Togo. This survey was conducted over a period of two months from September to November, 2010. During Togo'sMICS4 survey, 2067 children met the inclusion criteria for our study. Female children accounted for 50.9 % (1051/2067) of the sample and 1372 (66.4 %) lived in rural areas. The majority of children (92.2 %; 1905/2067) lived with both parents and 30 % of the head of households interviewed were not schooled (620/2067). At the time of the survey, 36.2 % (750/2067) of the children had not received all vaccines recommended by Expanded Program on Immunization (EPI). In multivariate analysis, factors associated with incompleteness of immunization at 1 year were: health region of residences (Maritime aOR = 0.650; p = 0.043; Savanes: aOR = 0.324; p immunization coverage among children in Togo remains high. It is necessary to strengthen health promotion among the population in order to improve the use of immunization services that are essential to reduce morbidity and mortality among under five years old children.

    To monitor compliance with the International Code of Marketing of Breastmilk Substitutes in health systems, sales outlets, distribution points, and the news media in Togo and Burkina Faso, west Africa. Multisite cross sectional survey. Staff at 43 health facilities and 66 sales outlets and distribution points, 186 health providers, and 105 mothers of infants aged market commercial breast milk substitutes were found in 29 (44%) sales and distribution points. Forty commercial breast milk substitutes violated the labelling standards of the code: 21 were manufactured by Danone, 11 by Nestlé, and eight by other national and international manufacturers. Most (148, 90%) health providers had never heard of the code, and 66 mothers (63%) had never received any counselling on breast feeding by their health providers. In west Africa manufacturers are violating the code of marketing of breast milk substitutes. Comparable levels of code violations are observed with (Burkina Faso) or without (Togo) regulating legislation. Legislation must be accompanied by effective information, training, and monitoring systems to ensure that healthcare providers and manufacturers comply with evidence based practice and the code.

  12. Assessing the impact of climate change on smallholder farmers’ crop net revenue in Togo

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available This study employs a Ricardian modelling approach to measure the impact of climate change variables such as temperature and rainfalls on smallholder famers’ crop net revenue in Togo. The obtained results show that climate has a nonlinear effect on crop net revenue. In rainy season, the marginal impact of temperature on farmers’ net revenue is negative, while the impact of rainfalls is positive. The scenarios of decrease of rainfalls and/or increase of the temperature show negative impacts on the agriculture of Togo given the already harsh climatic conditions in the country. Other variables such as educational attainment, access to extension services and livestock ownership are found to have positive impact on farmers’ crop net revenue. Consequently, policies aimed at improving those factors could improve smallholder farmers’ wellbeing.

    2013-12-01

    The objectives of this paper are to grasp the current status of an endemic disease, known as Buruli ulcer (BU), in the Republic of Togo and the expansion of international assistance in the field. By adopting the explicit support model, this paper also compares the obtained research results with those of the Republic of Ghana and Benin, to clarify the primary functions played among respective governments, WHO, and NGO. Under the auspices of the WHO Global Buruli Ulcer Initiative (GBUI, 1998-), National Buruli Ulcer Control Programme (NBUCP) in the Togo was initiated in 1999. However, due to the shortage of national budget and politico-economic instabilities of the nation, the actual implementation of NBUCP proved to be problematic. It was after 2007 that the programme began to move forward with the interventions of NGOs like DAHW and Handicap International. Currently, major players involved in the implementation of the policies provided by the GBUI are WHO, NGOs and the targeted governments. In other words, the organizations involved in BU treatment work together by fulfilling their functions. Unlike the neighboring countries, the Togolese government encountered much difficulty in materializing its national programme. Largely due to the political instability and the severe shortage of national budget, stronger assistances from NGOs were required at various levels of the national health measures from formulating to implementing the programme. As the programmes in Togo and Ghana/Benin expanded over the years, the respective support model revealed to be unique and different. In Ghana and Benin, intimate cooperation among WHO, government and NGOs has been established. In Togo, strengthening of collaboration among the three players is expected.

    Stigma and discrimination experienced by people living with HIV (PLWHA) prevent and delay access to prevention and treatment services. The aim of this study was to describe the patterns of stigma and discrimination experienced by PLWHA in Togo and to identify the associated factors. A cross-sectional study was conducted in 2013 among PLWHA in Togo in order to collect data on stigma or discrimination experiences. Univariate and multivariate analyses were performed to identify associated factors. A total of 891 PLWHA were interviewed, including 848 (95.2%) receiving antiretroviral therapy. External stigma (37.9%) was the major form of stigmatization followed by internalized stigma (35.4%). The main features of external stigma were gossip (36.5%) and issues to access education (36.0%). Internalized stigma mainly consisted of a feeling of guilt (37.6%) and self-devaluation (36.0%). In univariate and multivariate analysis, female gender was significantly associated with stigma (aOR = 1.73, 95% CI [1.08-2.77]). Of the 891 PLWHA, 75 (8.4%) reported a violation of their rights. Finally 27 (4.1%) were discouraged from having children by a health professional because of their HIV status. Stigma affects more than one-third of PLWHA in Togo, more particularly females. It appears necessary to design new interventions and integrate psychosocial care in the management of PLWHA, in addition to antiretroviral therapy.

    Full Text Available Yam is a strategic crop in Togo. Inventory and evaluation of cultivated varieties in different traditional agroeco-systems allows safeguard of this genetic heritage and its use in breeding programs. As welle ethnobotanical surveys were conducted in 30 localities of Kara region. The inventory allowed the recording 134 yam varieties distributed as follow 122 of D. cayenensis D. rotundata complex (56.46% early varieties and 43.54% late varieties and 12 varieties of the type D. alata. The varietal richness by site varies betewen 7 and 30 with a predominance of D. cayenensis-D. rotundata. Varietal diversity has increased in 22% of villages because of varietal introductions representing 19.2% of the varieties. They come mainly from Bénin (52%, Ghana (40% and Nigeria (8%. The exchange (45%, inheritance (65%, the gift (72.5% and the purchase (35% are the varieties acquisition modes. In contrast to 78% of the localities there is a reduction of varietal diversity. Ten main factors mainly agronomic and social are the cause of the reduction. 83% of the varieties are sparsely distributed and require urgent action on farm conservation because they are endangering.

    In Togo, many persons still rely on plants for healing, however very little is known about the medicinal practices of the indigenous people. The present study aimed to document the medicinal plant utilization for the management of liver diseases in the Maritime region of the country. This was an ethnobotanical survey conducted in the Maritime region of Togo from June to August 2015. The data were gathered from 104 traditional healers (TH) by direct interviews using a semi-structured questionnaire. The calculated use values (UV) were used to analyze the importance of the cited plants. A total of 99 plant species belonging to 88 genera and 49 families were cited by the TH as curing the hepatic diseases. The most represented families were Caesalpiniaceae with 8 species, followed by Euphorbiaceae with 7 species, Apocynaceae and Asteraceae with 6 species each. The highest UV were recorded with Gomphrena celosioides (0.13), Xylopia ethiopica (0.12), Senna occidentalis (0.12), Bridelia ferruginea (0.12), Cymbopogon citratus (0.12), Kigellia Africana (0.09), Cassia sieberiana (0.08) and Sanseviera liberica (0.08), showing their importance in the management of liver dysfunction in the surveyed region. The main used parts were the leaves, followed by the roots, the whole plant, the rhizome and the bark, accounting for more than 10% each. The herbal medicines were mostly prepared in the form of decoction and administrated by oral route. This study showed that Maritime region of Togo has an important plant biodiversity that is exploited by the indigenous TH. However, some plants cited by the TH have not been studied for their possible hepatoprotective effects. These plants are therefore a starting point for biological screenings.

    During the last ten years, a resurgence of syphilis has occurred in many countries worldwide, including Togo. Previous studies have shown a wide range of syphilis infection among the female sex workers (FSWs), from 1.5 to 42.1%. In Togo, Key populations, including FSWs, are rarely involved in the sentinel surveillance programs to determine the prevalence of HIV and syphilis. The aim of this study was to determine the prevalence of syphilis among female sex workers (FSWs) and their clients in Togo. We conducted a cross-sectional study in December 2011 targeting FSWs and their clients in Togo. Among participant who consented, we collected blood samples for syphilis and HIV testing. In total, 1,836 participants (1,106 FSWs and 730 clients) were included in the survey. Their mean age was 28.6 ± 9 years. The prevalence of syphilis was 2.2% (2.2% among FSWs compare to 2.3% among their clients, p = 0.82). This prevalence was higher among FSWs over 30 years old compare to those less than 30 years old (Odd Ratio (OR) =5.03; 95% CI [1.95-13.49]). Single FSWs were three times less likely to have syphilis than those living in couple or married (OR = 3.11; CI 95% [1.16-8.83]). Brothel based or declared FSWs were 4 times more likely to be infected by syphilis than secret ones (OR = 3.89; CI 95% [1.60-9.54]). Out of the 1,836 participants of the survey, 165 (8.9%) were HIV positive. Having syphilis was associated with HIV infection (OR = 3.41; IC 95% [1.53-7.41]). This study showed that: i) the prevalence of syphilis among FSWs and their clients was high; ii) syphilis was significantly associated with HIV infection. It is necessary to increase awareness campaigns and emphasize on condom use among this key population group.

  2. Consistent Condom Use during Casual Sex among Long-Truck Drivers in Togo.

    Directory of Open Access Journals (Sweden)

    Issifou Yaya

    Full Text Available In 2008, the proportion of truck drivers who were not systematically protected during sex was 63% with casual partners and 60% with sex workers. Despite the high level of knowledge on HIV/AIDS and the growing awareness of the existence of the risk of HIV infection, condom use always encounters resistance among truck drivers in Togo. We sought to document the factors associated with condom use during casual sex among trucks' drivers in Togo.This was an analytical cross-sectional study conducted in 2010 and targeted truckers at truck station on the two main roads of Togo, Lomé-Cinkassé and Kodjoviakopé-Sanvee Condji.In this study, 1,782 trucks' drivers and their helpers were interviewed. All were men, and their mean age was 28.8 ± 8.8 years. Trucks' drivers were doing an average of 3 stops on their journeys and 1,229 (69% of them had at least two years of experience in the work. Of the 1,782 trucks' drivers, only 620 (34.8% had consistently used condoms during casual sex in the last three months. In multivariate analysis, predictors were: education level (primary schooling: OR = 1.54; p = 0.002; Secondary schooling and higher OR = 1.38; p = 0.036, good knowledge of ways of HIV transmission (OR = 1.53; p = 0.000, tested for HIV (OR = 1.67, p = 0.000, duration in the profession (2-5 years: OR = 1.43, p = 0.008; more than 5 years: OR = 1.38, p = 0.027, and HIV risk's perception (OR = 1.44, p = 0.000.These results highlight factors associated with consistent condom use during casual sex by truck drivers in Togo. This is a key population group at high risk of HIV transmission toward which the national HIV/AIDS control program should strengthen the HIV prevention strategies.

    Dovi-sodemekou, F B

    1985-01-01

    Togo is a developing country whose population is increasing at the rapid rate of 2.7%/year. Economic development is therefore a necessity to ensure at least an average standard of living. Plans of development include objectives of structural societal changes, including improvements in education and employment. This study analyzes the evolution of population activities. It identifies obstacles to the improvement of education and employment. The investigation examines the employment and education situation before adoption of the 2nd plan of Togo and predicts the probable evolution of the situation. Despite the priority accorded to agriculture, the 2nd plan appears to give greater importance to industry. The industrial and commercial sector has witnessed a 65.2% investment increase, whereas the rural sector had an investment increase of 11.8%. The 2nd plan, in view of its relation to the evolution of economic activities, took into account the demand for manual labor. In the private sector, industries should occupy an important position. The dualism of a modern and a traditional sector is considered a cause of underdevelopment. The modern sector should be developed in order to suppress the traditional sector and allow progress in society. As a result of this approach, agriculture is given a 2ndary role.

    Providing quality care for all children living with HIV/AIDS remains a global challenge and requires the development of new healthcare delivery strategies. The care delivery value chain (CDVC) is a framework that maps activities required to provide effective and responsive care for a patient with a particular disease across the continuum of care. By mapping activities along a value chain, the CDVC enables managers to better allocate resources, improve communication, and coordinate activities. We report on the successful application of the CDVC as a strategy to optimize care delivery and inform quality improvement (QI) efforts with the overall aim of improving care for Pediatric HIV patients in Togo, West Africa. Over the course of 12 months, 13 distinct QI activities in Pediatric HIV/AIDS care delivery were monitored, and 11 of those activities met or exceeded established targets. Examples included: increase in infants receiving routine polymerase chain reaction testing at 2 months (39-95%), increase in HIV exposed children receiving confirmatory HIV testing at 18 months (67-100%), and increase in patients receiving initial CD4 testing within 3 months of HIV diagnosis (67-100%). The CDVC was an effective approach for evaluating existing systems and prioritizing gaps in delivery for QI over the full cycle of Pediatric HIV/AIDS care in three specific ways: (1) facilitating the first comprehensive mapping of Pediatric HIV/AIDS services, (2) identifying gaps in available services, and (3) catalyzing the creation of a responsive QI plan. The CDVC provided a framework to drive meaningful, strategic action to improve Pediatric HIV care in Togo.

    2017-01-01

    Full Text Available Background. Lassa fever belongs to the group of potentially fatal hemorrhagic fevers, never reported in Togo. The aim of this paper is to report the first two cases of Lassa fever infection in Togo. Case Presentation. The two first Lassa fever cases occurred in two expatriate’s health professionals working in Togo for more than two years. The symptoms appeared among two health professionals of a clinic located in Oti district in the north of the country. The absence of clinical improvement after antimalarial treatment and the worsening of clinical symptoms led to the medical evacuation. The delayed diagnosis of the first case led to a fatal outcome. The second case recovered under ribavirin treatment. Conclusion. The emergence of this hemorrhagic fever confirms the existence of Lassa fever virus in Togo. After a period of intensive Ebola virus transmission from 2013 to 2015, this is an additional call for the establishment and enhancement of infection prevention and control measures in the health care setting in West Africa.

    Kempner, Ken; de Moura Castro, Claudio; Bas, Daniel

    1993-09-01

    This paper explores the economic and cultural reasons why apprenticeship programmes imported by developing countries typically fail. The authors pursue this inquiry in a comparative manner by addressing experiences in Western Africa and by drawing on the outcomes of apprentice programmes in some industrialised countries. The authors identify major issues that explain why programmes borrowed from the West are so ineffective in Africa. Essentially, the imported apprenticeship programmes are decidedly Western and white concepts that link education to employment through certification and individual ownership of knowledge, and that clash with African cultural traditions. Individual success is central to Western-based programmes, which is opposed to more community-based conceptions of traditional African culture. Because of this inherent mismatch, the authors conclude with several options for developing apprenticeship training in Africa that are more relevant and adaptable to the prevailing cultural, educational and economic climate. They encourage programmes that improve the educational system incrementally and caution against programmes that run counter to the predominant culture.

    2009-06-01

    Full Text Available The aerial parts essential oils of Ocimum basilicum (Lamiaceae from Togo were steam-distilled and investigated for their percentage composition (GC and GC/MS and in vitro antimicrobial activities. Five oil chemotypes were identified and classified as follows in line with their principal components: estragole type; linalool/estragole type; methyleugenol type; methyleugenol/t-anethole type; t-anethole type. The in vitro microbiological experiments revealed that only the methyleugenol and methyleugenol/t-anethole chemotypes were active against tested fungi and bacteria. Their minimum inhibitory concentrations (MIC ranged from 80 to 150 µl.l-1 and from 200 to 500 µl.l-1 respectively. Likewise, on tested bacteria the MIC varied from 200 µl.l-1 to 400 µl.l-1 and from 250 to 500 µl.l-1 respectively. These findings are supportive of the potential of both basil oil chemotypes for use as active ingredients in natural antibiotic drugs.

    2012-01-01

    In Africa the majority of solid waste data is for big cities. Small and rural towns are generally neglected and waste data from these areas are often unavailable, which makes planning a proper solid waste management difficult. This paper presents the results from two waste characterization projects...... conducted in Kétao, a rural town in Togo during the rainy season and the dry season in 2010. The seasonal variation has a significant impact on the waste stream. The household waste generation rate was estimated at 0.22 kg person−1 day−1 in the dry season and 0.42 in the rainy season. Likewise, the waste...... moisture content was 4% in the dry season while it was 33–63% in the rainy season. The waste consisted mainly of soil and dirt characterized as ‘other’ (41%), vegetables and putrescibles (38%) and plastic (11%). In addition to these fractions, considerable amounts of material are either recycled or reused...

    2014-01-01

    In Togo, more than six hundred species of horticultural plants were identified belonging to approximately 59% of Dicotyledons (49 families, 145 genera and 315 species) and 37.37% were monocotyledons. Pteridophytes and gymnosperms accounted for less than 6%. The spectrum of morphological types indicated that herbs accounted for 55%, while trees and shrubs were 15%. More than 50% of the species of this flora were exotic. The species distributions were made according to their decorative parts and their place of use. Across the country, 55 plantings were recorded and unevenly distributed in cities. Apart from their ornamental use, these plants were used for feeding, traditional and industrial cosmetics in psychotherapy, horticultural therapy and in traditional and conventional medicine preparation. In this study, 79 species from 39 families are reported as medicinal plants. The Apocynaceae and Fabaceae (6 species), the Euphorbiaceae and Liliaceae (5 species), the Arecaceae and Verbenaceae (4 species) were the best represented families. (author)

  15. The colony as laboratory: German sleeping sickness campaigns in German East Africa and in Togo, 1900-1914.

    Eckart, Wolfgang U

    2002-01-01

    This paper is on dangerous human experimentations with drugs against trypanosimiasis carried out in the former German colonies of German East Africa and Togo. Victory over trypanosomiasis could not be achieved in Berlin because animals were thought to be unsuitable for therapeutic laboratory research in the field of trypanosomiasis. The colonies themselves were necessarily chosen as laboratories and the patients with sleeping sickness became the objects of therapeutical and pharmacological research. The paper first outlines Robert Koch's trypanosomiasis research in the large sleeping sickness laboratory of German East Africa and then focuses on the escalating human experiments on trypanosomiasis in the German Musterkolonie Togo, which must be interpreted as a reaction to the starting signal given by Robert Koch in East Africa.

    Few studies have examined the association between childhood maltreatment (CM) and personality disorders (PDs) in adulthood in two different cultural contexts, including sub-Saharan Africa. The aims of this study were to compare the frequency of CM between patients in treatment in France and Togo for a major depressive disorder (MDD), to explore the link between CM and PDs, and to examine the mediating effect of personality dimensions in the pathway from CM to PDs in 150 participants (75 in each country). The 28-item Childhood Trauma Questionnaire, the International Personality Item Pool, and the Personality Diagnostic Questionnaire (PDQ-4+) were used to assess CM, personality dimensions, and PDs respectively. Togolese participants reported sexual and physical abuse (PA) and emotional and physical neglect significantly more frequently than French participants. In Togo, severe PA was associated with schizoid, antisocial, narcissistic, obsessive-compulsive, depressive, and negativist PDs whereas in France, PA was only linked to paranoid PD. In Togo, emotional instability partly mediated the relationship between CM and PDs while in France, no personality dimension appeared to mediate this link. Our results support the hypothesis that CM is more common in low-income countries and suggest that the links between CM and PDs are influenced by social environment. © The Author(s) 2015.

  17. Implementation of a national reference laboratory for Buruli ulcer disease in Togo.

    Directory of Open Access Journals (Sweden)

    Marcus Beissner

    Full Text Available BACKGROUND: In a previous study PCR analysis of clinical samples from suspected cases of Buruli ulcer disease (BUD from Togo and external quality assurance (EQA for local microscopy were conducted at an external reference laboratory in Germany. The relatively poor performance of local microscopy as well as effort and time associated with shipment of PCR samples necessitated the implementation of stringent EQA measures and availability of local laboratory capacity. This study describes the approach to implementation of a national BUD reference laboratory in Togo. METHODOLOGY: Large scale outreach activities accompanied by regular training programs for health care professionals were conducted in the regions "Maritime" and "Central," standard operating procedures defined all processes in participating laboratories (regional, national and external reference laboratories as well as the interaction between laboratories and partners in the field. Microscopy was conducted at regional level and slides were subjected to EQA at national and external reference laboratories. For PCR analysis, sample pairs were collected and subjected to a dry-reagent-based IS2404-PCR (DRB-PCR at national level and standard IS2404 PCR followed by IS2404 qPCR analysis of negative samples at the external reference laboratory. PRINCIPAL FINDINGS: The inter-laboratory concordance rates for microscopy ranged from 89% to 94%; overall, microscopy confirmed 50% of all suspected BUD cases. The inter-laboratory concordance rate for PCR was 96% with an overall PCR case confirmation rate of 78%. Compared to a previous study, the rate of BUD patients with non-ulcerative lesions increased from 37% to 50%, the mean duration of disease before clinical diagnosis decreased significantly from 182.6 to 82.1 days among patients with ulcerative lesions, and the percentage of category III lesions decreased from 30.3% to 19.2%. CONCLUSIONS: High inter-laboratory concordance rates as well as case

  18. Epidemiology of brucellosis and q Fever in linked human and animal populations in northern togo.

    Although brucellosis (Brucella spp.) and Q Fever (Coxiella burnetii) are zoonoses of global importance, very little high quality data are available from West Africa. A serosurvey was conducted in Togo's main livestock-raising zone in 2011 in 25 randomly selected villages, including 683 people, 596 cattle, 465 sheep and 221 goats. Additionally, 464 transhumant cattle from Burkina Faso were sampled in 2012. The serological analyses performed were the Rose Bengal Test and ELISA for brucellosis and ELISA and the immunofluorescence assay (IFA) for Q Fever Brucellosis did not appear to pose a major human health problem in the study zone, with only 7 seropositive participants. B. abortus was isolated from 3 bovine hygroma samples, and is likely to be the predominant circulating strain. This may explain the observed seropositivity amongst village cattle (9.2%, 95%CI:4.3-18.6%) and transhumant cattle (7.3%, 95%CI:3.5-14.7%), with an absence of seropositive small ruminants. Exposure of livestock and people to C. burnetii was common, potentially influenced by cultural factors. People of Fulani ethnicity had greater livestock contact and a significantly higher seroprevalence than other ethnic groups (Fulani: 45.5%, 95%CI:37.7-53.6%; non-Fulani: 27.1%, 95%CI:20.6-34.7%). Appropriate diagnostic test cut-off values in endemic settings requires further investigation. Both brucellosis and Q Fever appeared to impact on livestock production. Seropositive cows were more likely to have aborted a foetus during the previous year than seronegative cows, when adjusted for age. This odds was 3.8 times higher (95%CI: 1.2-12.1) for brucellosis and 6.7 times higher (95%CI: 1.3-34.8) for Q Fever. This is the first epidemiological study of zoonoses in Togo in linked human and animal populations, providing much needed data for West Africa. Exposure to Brucella and C. burnetii is common but further research is needed into the clinical and economic impact.

    The aim of this study was to describe features of self-medication for skin conditions observed at public dermatology centres in Lome, Togo. This cross-sectional study was conducted from July 1 to September 30, 2008 in 3 public dermatology centres in Lome-Commune. All patients consulting at the study centres for the first time were recruited, interviewed and examined. Of 600 patients enlisted in the study, 264 (44%) had practiced self-medication. There were more women than men (sex ratio: 0.8). In most cases, products used for self-medication were recommended by a friend and/or relative (72%). Most products were obtained from either pharmacies (42.4%) or street vendors (37.9%). The average cost of self-medication was 520 FCFA (0.79 euros). Products applied by the topical route were the most common (72%) and most patients reported dissatisfaction with results (67.8%). This study demonstrates that self-medication is widely practiced for dermatologic conditions in Lome and provides insight into the circumstances, reasons and sources of self-medication.

    2014-01-01

    Full Text Available Background. Reproductive health programming for female sex workers (FSW may include contraceptive services but rarely addresses safer pregnancy planning. Methods. Adult FSW were enrolled into a cross-sectional study across four sites in Burkina Faso and Togo using respondent-driven sampling. Sociobehavioral questionnaires and HIV counseling and testing were administered. Sample statistics and engagement in HIV treatment were described and compared using Chi-squared statistics. Results. 1,349 reproductive-aged FSW were enrolled from January to July 2013. Overall, 267 FSW (19.8% were currently trying to conceive. FSW trying to conceive were more likely to test positive for HIV at enrollment as compared to women not trying to become pregnant (24.5% versus 17.7%, P<0.01; however awareness of HIV status was similar across groups. Among FSW trying to conceive, 79.0% (211/267 had previously received HIV testing, yet only 33.8% (23/68 of HIV-infected FSW reported a previous HIV diagnosis. Overall 25.0% (17/68 of HIV-infected FSW trying to conceive were on antiretroviral therapy. Conclusion. FSW frequently desire children. However engagement in the HIV prevention and treatment cascade among FSW trying to conceive is poor potentiating periconception transmission risks to partners and infants. Programs to facilitate earlier HIV diagnosis for FSW and safer conception counseling are needed as components of effective combination HIV prevention services.

    2008-09-01

    Microbiological and physicochemical qualities of a tomato (Lycopersicon esculentum) puree production line (ripe tomato, washing, cutting, pounding, bleaching, straining, bottling and pasteurization) and its preservation in Togo, West Africa, were studied using the HACCP method. Samples generated during the steps described previously were analyzed by determining sensory, chemical and microbiological characteristics. Samples were analyzed using MPN for coliform populations and plate count methodology for other bacteria. The microorganisms involved in spoilage of the opened products were moulds of genera Penicillium, Aspergillus, Fusarium, Geotrichum, Mucor and gram-positive Bacillus bacteria. The preserved tomato puree exhibited a pH value of 4.3, 90% water content, 0.98 water activity (aw) and an average ascorbic acid level of 27.3mg/100g. Results showed that the critical control point (CCP) of this tomato puree processing line is the pasteurization stage. The analysis of selected microbiological and physicochemical parameters during the preservation of bottled tomato puree indicated that this product was stable over 22 months at 29 degrees C. But the stability of the opened product stored at 29 degrees C did not exceed two months.

  2. Effect of Climatic and Non-Climatic Factors on Cassava Yields in Togo: Agricultural Policy Implications

    Directory of Open Access Journals (Sweden)

    David Boansi

    2017-03-01

    Full Text Available This paper examines the effects of climatic and non-climatic factors on cassava yields in Togo using an Autoregressive Distributed Lag (ARDL modelling approach and pairwise Granger Causality tests. Secondary data on production statistics, rural population, climate variables, prices and nominal exchange rate for the period 1978–2009 are used. Results for estimated short- and long-run models indicate that cassava yield is affected by both ‘normal’ climate variables and within-season rainfall variability. An inverse relationship is found between area harvested and yield of cassava, but a significant positive and elastic effect of labour availability on yield in the long run. Increasing within-lean-season rainfall variability and high lean-season mean temperature are detrimental to cassava yields, while increasing main-season rainfall and mean-temperature enhance cassava yields. Through Granger Causality tests, a bilateral causality is found between area harvested and yield of cassava, and four unidirectional causalities from labour availability, real producer price ratio between yam and cassava, main-season rainfall and lean-season mean temperature to cassava yields. Based on the findings from this study, investment in low-cost irrigation facilities and water harvesting is recommended to enhance the practice of supplemental irrigation. Research efforts should as well be made to breed for drought, heat and flood tolerance in cassava. In addition, coupling area expansion with increasing availability of labour is advised, through the implementation of measures to minimize rural–urban migration.

    The twofold purpose of this study in people living with human immunodeficiency virus (PLHIV/AIDS) and undergoing highly active antiretroviral treatment (HAART) was to determine the prevalence of ocular manifestations and its correlation with CD4 T-cell count. All patients who attended 2 NGO care centers that manage PLHIV/AIDS in Lomé, Togo between August and October 2005 were recruited. CD4 T-cell counts and use of antiretroviral treatment was noted. A thorough eye examination was performed in all cases. A total of 422 PLHIV/SIDA were recruited including 281 who were undergoing HAART. The sex-ratio was 2 female/1 male. Mean age was 34 +/- 2294 years. Involvement of the anterior segment was observed in 36.3% of patients and involvement of the posterior segment in 54.1%. The second most common ocular manifestation was ophthalmic herpes zoster of the anterior segment (19.6%) secondary to conjunctivitis (57.8%). One case of palpebral and conjunctival Kaposi's sarcoma was noted. The most common type of posterior segment involvement was cotton-wool nodules (35.5%). Five cases of CMV retinitis were observed. A longitudinal study in PLHIV/AIDS will be needed to better evaluate the correlation between ocular manifestations and CD4 T-cell count.

    In recent years, biological web resources such as databases and tools have become more complex because of the enormous amounts of data generated in the field of life sciences. Traditional methods of distributing tutorials include publishing textbooks and posting web documents, but these static contents cannot adequately describe recent dynamic web services. Due to improvements in computer technology, it is now possible to create dynamic content such as video with minimal effort and low cost on most modern computers. The ease of creating and distributing video tutorials instead of static content improves accessibility for researchers, annotators and curators. This article focuses on online video repositories for educational and tutorial videos provided by resource developers and users. It also describes a project in Japan named TogoTV (http://togotv.dbcls.jp/en/) and discusses the production and distribution of high-quality tutorial videos, which would be useful to viewer, with examples. This article intends to stimulate and encourage researchers who develop and use databases and tools to distribute how-to videos as a tool to enhance product usability.

    Full Text Available This study, conducted as part of our overall goal of regular pharmacovigilance of antimalarial medicines, reports on the quality of 132 artemisinin-based antimalarial medicines distributed in Ghana and Togo. Three methods were employed in the quality evaluation—basic (colorimetric tests for establishing the identity of the requisite active pharmaceutical ingredients (APIs, semi-quantitative TLC assay for the identification and estimation of API content, and HPLC assay for a more accurate quantification of API content. From the basic tests, only one sample totally lacked API. The HPLC assay, however, showed that 83.7% of the ACTs and 57.9% of the artemisinin-based monotherapies failed to comply with international pharmacopoeia requirements due to insufficient API content. In most of the ACTs, the artemisinin component was usually the insufficient API. Generally, there was a good correlation between the HPLC and SQ-TLC assays. The overall failure rates for both locally manufactured (77.3% and imported medicines (77.5% were comparable. Similarly the unregistered medicines recorded a slightly higher overall failure rate (84.7% than registered medicines (70.8%. Only two instances of possible cross-border exchange of medicines were observed and there was little difference between the medicine quality of collections from border towns and those from inland parts of both countries.

    Full Text Available The leaf essential oils of Cymbopogon citratus L. and Cymbopogon nardus L.(Poaceae from Togo were steam-distilled, analyzed for percentage composition and investigated in vitro for their potential cytotoxic activity on human epidermic cell line HaCat. The percentage composition showed that the main constituents of essential oils samples were respectively geranial (45.2%, neral(32.4% and myrcène (10.2% for C. citratus essential oil and citronellal (35.5%, geraniol (27.9% and citronellol (10.7% for that of C. nardus. The in vitro cytotoxicity bioassays on human epidermic cell line HaCaT revealed that the toxicityof the essential oil from C. citratus (IC50: 150 μL.mL-1 was higher than that of the essential oil from C. nardus (IC50: 450 μL.mL-1. Pure commercial neral, geranial, and citronellal standards showed respectively the following IC50 values: 100, 250 and 300 μL.mL-1. Conversely, pure citronellol standard appeared almost non-toxic (IC50>1000 μL.mL-1, proving the major role played in synergyby neral and geranial in the overall toxicity showed by the citratus oil sample tested in this work.

    Full Text Available Analysis of the agricultural system of the region of Ahépé, south Togo. The agricultural system of the region of Ahépé, 80 km north of Lomé, Togo, was studied. Eighteen historical surveys and 44 farm surveys were carried out. We distinguished four main stages in the evolution of the farming system in the region. 1. Pioneer farming based on burning, with fallow land lasting more than 20 years. 2. When access to land starts to decrease, and oil palm (Elaeis guineensis starts being the main source of revenue, the system becomes fallow-land with oil palm based. Such a system necessitates an available surface at least three times larger than the cultivated area. 3. Due to lack of available land, the third system is based on pruning and burning of oil palm fallow lands with alternative cultivation and fallow land every three years. 4. Finally, after cultivated land becomes really short, rural depopulation, sale of labour force, and work intensification per unit of surface and of capital areobserved. In the actual farming system, we distinguished 5 different categories of farms. The ""survival threshold"" (the minimal amount of resources needed, estimated for a family with two adults and three children, is F CFA 79,000 per working adult and per year, of which F CFA 47,000 in cash (to buy everything that cannot be produced on farm. The first category is a food-producing system on short time fallow-land with palm trees. With farms smaller than 1 ha, food crops are dominant (80% of the agricultural revenue and the total agricultural revenue per working adult is less than F CFA 200,000 per year. The second category is a food-producing system on short time fallow-land with palm trees and cash crops. The annual agricultural revenue per working adult varies from F CFA 200,000 to 1,600,000. In the third category, cash crops are dominant (mainly cotton but the farms are in difficult financial conditions. The surfaces in this system vary between 1.1 and 1

    Full Text Available Objective. This study aimed to determine the prevalence of and factors associated with self-medication in dermatology in Lomé, Togo. Methods. We conducted an analytical cross-sectional study from February to April 2016 in 2 dermatology departments in Lomé. Univariate and multivariate logistic regression models were carried out to identify possible factors associated with self-medication. Results. A total of 711 patients were included in the study. The mean age (±SD of the patients was 26.6±6.9 years and the sex ratio (male/female was 0.6. The main dermatologic diseases recorded were immunoallergic dermatoses (39.7% and infectious skin diseases (22.6%. Two-thirds (481/711; 66.7% of the patients had practiced self-medication before consultation in dermatology units. In multivariate analysis, factors associated with self-medication were female sex (aOR = 1.44; 95% CI = [1.01, 2.05], duration of dermatologic disease more than one year (aOR = 1.79; IC = [1.19, 2.68], adnexal dermatoses (aOR = 2.31; 95% IC = [1.03–5.21], keratinization disorders (aOR = 4.23; 95% CI = [1.36–13.13], and fungal skin infections (aOR = 5.43; 95% CI = [2.20, 13.38]. Conclusion. Our study confirms that self-medication practice is very common among patients with dermatologic diseases in Lomé and has identified associated factors.

    The purpose of this study was to describe the epidemiological and clinical profile and the treatment and natural history of AIDS-related Kaposi sarcoma in 3 major dermatology departments in Lomé (Togo). This retrospective, descriptive study was based on the records of patients with AIDS-related Kaposi sarcoma from January 2005 through October 2011. During the study period, 157 patients were treated in the dermatology departments for Kaposi sarcoma. HIV serology was positive for 103 (89.6%) of the 115 patients tested. Seventy-nine patients were known to be HIV-positive before the consultation, while Kaposi sarcoma was the circumstance of discovery of the HIV infection for 24. The average age of the 103 patients was 36.7±14.9 years and the sex-ratio (M/F) was 1.1. The main locations of the lesions were the lower limbs (n = 76), mucosa (n = 53), trunk (n = 38) and upper limbs (n = 17). The average CD4-cell count was 226±168 cells/mm(3). The main antiretroviral protocol used was stavudine/lamivudine/nevirapine (70 cases). Besides the antiretroviral treatment, chemotherapy was prescribed, with vinblastine for 17 patients, bleomycin for 5, and doxorubicin for one. For financial reasons, 80 other patients did not receive chemotherapy and were lost to follow-up after an average duration of 3 months. At 5 months, the rate of complete remission was 21.1%, partial remission 21.1%, and failure 57.8%. Side effects were dominated by hematologic and nervous complications. Our study highlighted a high prevalence of AIDS-related Kaposi sarcoma in dermatology departments in Lomé, with a tendency to gender equality. It also shows the difficulties of access to chemotherapy for most patients and the poor efficacy of chemotherapy.

  14. National-level differences in the adoption of environmental health technologies: a cross-border comparison from Benin and Togo.

    Environmental health problems such as malaria, respiratory infections, diarrhoea and malnutrition pose very high burdens on the poor rural people in much of the tropics. Recent research on key interventions-the adoption and use of relatively cheap and effective environmental health technologies-has focused primarily on the influence of demand-side household-level drivers. Relatively few studies of the promotion and use of these technologies have considered the role of contextual factors such as governance, the enabling environment and national policies because of the challenges of cross-country comparisons. We exploit a natural experimental setting by comparing household adoption across the Benin-Togo national border that splits the Tamberma Valley in West Africa. Households across the border share the same culture, ethnicity, weather, physiographic features, livelihoods and infrastructure; however, they are located in countries at virtually opposite ends of the institutional spectrum of democratic elections, voice and accountability, effective governance and corruption. Binary choice models and rigorous non-parametric matching estimators confirm that households in Benin are more likely than households in Togo to plant soybeans, build improved cookstoves and purchase mosquito nets, ceteris paribus. Although we cannot identify the exact mechanism for the large and significant national-level differences in technology adoption, our findings suggest that contextual institutional factors can be more important than household characteristics for technology adoption.

    Background Although brucellosis (Brucella spp.) and Q Fever (Coxiella burnetii) are zoonoses of global importance, very little high quality data are available from West Africa. Methods/Principal Findings A serosurvey was conducted in Togo’s main livestock-raising zone in 2011 in 25 randomly selected villages, including 683 people, 596 cattle, 465 sheep and 221 goats. Additionally, 464 transhumant cattle from Burkina Faso were sampled in 2012. The serological analyses performed were the Rose Bengal Test and ELISA for brucellosis and ELISA and the immunofluorescence assay (IFA) for Q Fever Brucellosis did not appear to pose a major human health problem in the study zone, with only 7 seropositive participants. B. abortus was isolated from 3 bovine hygroma samples, and is likely to be the predominant circulating strain. This may explain the observed seropositivity amongst village cattle (9.2%, 95%CI:4.3–18.6%) and transhumant cattle (7.3%, 95%CI:3.5–14.7%), with an absence of seropositive small ruminants. Exposure of livestock and people to C. burnetii was common, potentially influenced by cultural factors. People of Fulani ethnicity had greater livestock contact and a significantly higher seroprevalence than other ethnic groups (Fulani: 45.5%, 95%CI:37.7–53.6%; non-Fulani: 27.1%, 95%CI:20.6–34.7%). Appropriate diagnostic test cut-off values in endemic settings requires further investigation. Both brucellosis and Q Fever appeared to impact on livestock production. Seropositive cows were more likely to have aborted a foetus during the previous year than seronegative cows, when adjusted for age. This odds was 3.8 times higher (95%CI: 1.2–12.1) for brucellosis and 6.7 times higher (95%CI: 1.3–34.8) for Q Fever. Conclusions This is the first epidemiological study of zoonoses in Togo in linked human and animal populations, providing much needed data for West Africa. Exposure to Brucella and C. burnetii is common but further research is needed into the clinical

    Sustainable control of soil-transmitted helminths requires a combination of chemotherapy treatment and environmental interventions, including access to safe drinking water, sufficient water for hygiene, use of clean sanitation facilities, and handwashing (WASH). We quantified associations between home-, school-, and community-level WASH characteristics and hookworm infection-both prevalence and eggs per gram of stool (intensity)-among Togolese school children in the context of community-based chemotherapy treatments administered in the country from 2010 through 2014. We analyzed data from two surveys conducted by the Togo Ministry of Health: a school-based survey of students aged 6-9 years across Togo conducted in 2009 and a follow-up survey in 2015, after four to five years of preventive chemotherapy. Data were available for 16,473 students attending 1,129 schools in 2009 and for 16,890 students from 1,126 schools in 2015. Between surveys, children in study schools received 0 to 8 rounds of deworming chemotherapy treatments. Few WASH conditions (only unimproved drinking water) were found to be significantly associated with the presence or absence of hookworms in an individual; however, quantitative eggs per gram of feces was associated with availability of unimproved drinking water, availability of improved drinking water either on or off school grounds, having a handwashing station with water available, and access to a sex-separate non-private or private latrine. The association between school WASH conditions and hookworm infection or burden often depended on the 2009 prevalence of infection, as more WASH characteristics were found to be significant predictors of infection among schools with high underlying endemicity of hookworm. Our findings emphasize the complex and often inconsistent or unpredictable relationship between WASH and hookworm. Specifically, we found that while preventive chemotherapy appeared to dramatically reduce hookworm infection, WASH was

    After losing the importance it had held around 1900 both as a colonial power and in the field of tropical medicine, Germany searched for a new place in international health care during decolonisation. Under the aegis of early government ‘development aid’, which started in 1956, medical academics from West German universities became involved in several Asian, African and South American countries. The example selected for closer study is the support for the national hygiene institute in Togo, a former German ‘model colony’ and now a stout ally of the West. Positioned between public health and scientific research, between ‘development aid’ and academia and between West German and West African interests, the project required multiple arrangements that are analysed for their impact on the co-operation between the two countries. In a country like Togo, where higher education had been neglected under colonial rule, having qualified national staff became the decisive factor for the project. While routine services soon worked well, research required more sustained ‘capacity building’ and did not lead to joint work on equal terms. In West Germany, the arrangement with the universities was a mutual benefit deal for government officials and medical academics. West German ‘development aid’ did not have to create permanent jobs at home for the consulting experts it needed; it improved its chances to find sufficiently qualified German staff to work abroad and it profited from the academic renown of its consultants. The medical scientists secured jobs and research opportunities for their postgraduates, received grants for foreign doctoral students, gained additional expertise and enjoyed international prestige. Independence from foreign politics was not an issue for most West German medical academics in the 1960s. PMID:27998330

    To identify the rare hemoglobins (Hbs) encountered in Togo and characterize their geographical and ethnic distribution and hematologic expression. This retrospective descriptive study covers 27,530 hemoglobin electrophoresis tests performed in the department of Hematology of the Lomé Campus teaching hospital from January 1996 through December 2010, the national reference laboratory. The anomalies identified were studied with both alkaline and acid electrophoresis and high performance liquid chromatography (HPLC), all performed in Lome. Any other specialized examinations were conducted mainly at the biochemistry laboratories of either Robert Debre Hospital in Paris or Henri Mondor Hospital in Creteil (France). During the study period, 20 cases of a rare Hb were identified, i.e., 0.07% of all Hb analyses. These rare mutants were: HbK Woolwich (10 cases, 50% of the rare Hbs); HbD Korle-Bu (7 cases, 35%); HbJ Lome, G Philadelphia, and Hb Lepore (1 case each, 5% for each). Eighteen cases were associated with Hb A. Two cases of composite rare Hb were found: HbS/HbK Woolwich and HbC/Hb D Korle-Bu. Carriers of Hb Lepore and of HbC/HbD Korle-Bu had hypochromic and microcytic anemia. HbK Woolwich was found in the Adja-Ewé and Tem-Kabyé ethnic groups, in the Maritime and Kara regions; HbD Korle-Bu, HbJ Lome, and Hb Lepore were also identified among the Adja-Ewé, and HbG Philadelphia in the Akposso ethnic group of the Plateau zone. This study although limited to Lome, allowed us to identify the rare Hb forms observed in Togo. Other studies on a national scale will specify their real frequency.

    Full Text Available The fall armyworm (Spodoptera frugiperda, J.E. Smith is a noctuid moth that is a major and ubiquitous agricultural pest in the Western Hemisphere. Infestations have recently been identified in several locations in Africa, indicating its establishment in the Eastern Hemisphere where it poses an immediate and significant economic threat. Genetic methods were used to characterize noctuid specimens infesting multiple cornfields in the African nation of Togo that were tentatively identified as fall armyworm by morphological criteria. Species identification was confirmed by DNA barcoding and the specimens were found to be primarily of the subgroup that preferentially infests corn and sorghum in the Western Hemisphere. The mitochondrial haplotype configuration was most similar to that found in the Caribbean region and the eastern coast of the United States, identifying these populations as the likely originating source of the Togo infestations. A genetic marker linked with resistance to the Cry1Fa toxin from Bacillus thuringiensis (Bt expressed in transgenic corn and common in Puerto Rico fall armyworm populations was not found in the Togo collections. These observations demonstrate the usefulness of genetic surveys to characterize fall armyworm populations from Africa.

    The South Pan-African belt of West Africa (Ghana, Togo and Benin province) can be divided into three domains: (1) the external nappes thrust over the West African craton, derived from passive-margin sedimentary deposits (Middle to Late Proterozoic) and displaying middle- to high-pressure metamorphism, such as the Kanté and Atacora nappes; (2) the intermediate nappes including the suture-zone rocks with eclogitic assemblages (protoliths ca. 800 Ma), and mainly monocyclic metasedimentary rock and orthogneiss, that are found in central Togo and northwest Benin; (3) the internal nappes composed of high-grade commonly anatectic gneiss (anatexis ca. 600 Ma), including orthogneiss (Eburnian plutons), elongated granulite belts, reworked Archean basement, and an intrusive granite and charnockite association (ca. 600 Ma), which are exposed in Benin and Nigeria. The P- T- t- d paths calculated from rocks in these three domains show a prograde-retrograde evolution: (1) an initial clockwise evolution related to an early burial stage ( HP- HT in the intermediate nappes) followed by oblique thrusting in a SW direction, that caused nappe stacking and subsequent uplift; (2) a second anti-clockwise evolution with late temperature and pressure increases, only recorded in the more internal units. This temperature increase was a consequence of the previous crustal thickening with subsequent doming, extension and anatexis. The pressure increase was related to movement along the Kandi fault, working as a dextral strike-slip fault with a transpressional component under late E-W shortening. The retrograde trend corresponds to the final uplift. The evolution of the belt can thus be divided into three successive stages: (1) a first stage was characterized by an oblique collision inducing SW oblique thrusting with associated syn-foliation reverse metamorphism; (2) during a second stage anatectic doming took place; followed by (3) a third stage at still high temperature with dextral wrench

    Myasthenia gravis is a rare acquired autoimmune pathology causing neuromuscular transmission impairment. Juvenile onset of myasthenia gravis is often characterized by ocular involvement. We report two cases of ocular juvenile myasthenia gravis (JMG) in two siblings. They were two young girls, XA and XB, aged 11 and 9 years, of Malian origin, residing in Togo, born from first-degree of consanguinity presenting to Ophthalmology due to progressive decrease in visual acuity. XA showed visual acuity 8/10 on both eyes while XB showed improvement in visual acuity from 3/10 to 7/10 using a pinhole occluder, suggesting ametropia. XA had a 2-year history of bilateral ptosis lifting the upper eyelid of 7 mm, while XB had a 3-year history of bilateral ptosis with no lifting of the upper eyelid. Ice pack test was strongly positive in both patients. They had Cogan's lid twitch with paresis of the oculomotor nerve without diplopia. The dosage of acetylcholine receptor autoantibodies was normal. The diagnosis of JMG associated with ametropia was suspected. Ametropia was corrected by glasses and a specific treatment with pyridostigmine was initiated, but both patients were lost to follow-up. Autoimmune myasthenia gravis with inaugural ophthalmologic manifestation is rare but it can occur among children living in sub-Saharan Africa. Studies should be conducted to establish the features of this disease.

    Our study aimed to describe the epidemiological, clinical, and diagnostic aspects of African histoplasmosis in Togo through a descriptive and cross-sectional study on histological diagnosed African histoplasmosis in Pathology Department of Lomé from 2002 to 2016 (15 years). A total of 17 cases of African histoplasmosis were diagnosed. The sex ratio (M/F) was 1.8. The annual incidence was 1.1 cases. The mean age of the patients was 27.2 ± 0.4 years. All our patients were of social categories with a low socioeconomic level. HIV infection was known in 3 patients and one patient contracted tuberculosis. The clinical manifestations were cutaneous in 7 cases, cutaneous and mucous in 3 cases, cutaneous and lymph node in 3 cases, cutaneous and bone in 2 cases, and disseminated in 2 cases. The samples examined consisted of 14 cutaneous biopsies measuring 2-3 cm and 3 ganglionic biopsies each measuring 4 cm of major axis. Histologically, all cases were of chronic form made of granulomatous reaction with ovoid yeasts measuring between 1 and 2 microns. Despite the low frequency of this disease in our country, it should be kept constantly in mind before any granulomatous lesions, especially in the context of the HIV pandemic. PMID:28804654

    The aim of this work was to study the prevalence of skin diseases among inmates in Lomé (Togo) and its relation to their HIV status. This cross-sectional descriptive study took place from November 14 to December 5, 2011, in the civil prison of Lomé and included prisoners who agreed to have an HIV screening test. In all, 194 prisoners, all men (median age: 29 years), were examined during the study period. The group aged younger than 30 years accounted for 51% of the population. Overall, 166 (85.6%) of the 194 prisoners examined had cutaneous lesions; 153 reported that these had developed after their imprisonment. HIV serology was positive in 21 (10.8%) of the 194 prisoners tested. The most common cutaneous diseases were pruritus (n = 62), fungal infections (n = 45), boils (n = 26), eczema (n = 21), and scabies (n = 20). The frequency of skin disorders did not differ significantly between HIV-infected prisoners and those who were not infected (p>0.05). This study shows a potential for high prevalence of HIV infection and an existing high prevalence of infectious dermatosis among these prisoners. It is essential to reduce the overpopulation and crowding in prisons to decrease the prevalence of these skin disorders.

    Buruli ulcer (BU) is a neglected mycobacterial skin infection caused by Mycobacterium ulcerans. This disease mostly affects poor rural populations, especially in areas with low hygiene standards and sanitation coverage. The objective of this study was to identify these risk factors in the districts of Zio and Yoto of the Maritime Region in Togo. We conducted a case-control study in Zio and Yoto, two districts proved BU endemic from November 2014 to May 2015. BU cases were diagnosed according to the WHO clinical case definition at the Centre Hospitalier Régional de Tsévié (CHR Tsévié) and confirmed by Ziehl-Neelsen (ZN) microscopy and IS2404 polymerase chain reaction (PCR). For each case, up to two controls matched by sex and place of residence were recruited. Socio-demographic, environmental or behavioral data were collected and conditional logistic regression analysis was used to identify and compare risk factors between BU cases and controls. A total of 83 cases and 128 controls were enrolled. The median age was 15 years (range 3-65 years). Multivariate conditional logistic regression analysis after adjustment for potential confounders identified age (study identified age, bathing with water from open borehole and receiving insect bites near a river as potential risk of acquiring BU infection in Zio and Yoto districts of the Maritime Region in south Togo.

    To describe topographic characteristics of optic discs clinically suspected of large cupping. This is retrospective study conducted from the January 2 to December 31 on the OCT registry and data base of a private ophthalmologic center in Lomé (Togo). We included records of patients with large cupping - CDR (cup-to-disc ratio) ≥ 0.4 -clinically observed and having undergone OCT-optic disc analysis. Three hundred and thirty-five patients (619 eyes) were studied, with a mean age of 41.87 years±17.51 years [6 years and 80 years] and a sex-ratio of 1.01 with a slight female predominance. The mean clinical CDR was 0.51±0.126 [0.4 and 0.9] (95 % CI [0.503 to 0.531]). The clinical CDR was ≥ 0.7 in 7.75 % of cases. The mean neuroretinal rim area was 1.63±0.43 mm 2 [0.34 and 2.85 mm 2 ]. The mean cup area was 1.43±0.54 mm 2 [0.13 and 4.29 mm 2 ], and the mean cup volume 0.47±0.28 mm 3 [0.01 and 1.72 mm 3 ]. The mean global CDR on OCT was 0.46±0.13 [0.21 and 0.87], of which 30.85 % (191 cases) had CDR OCT was >0.7 in 40 (6.46 %) eyes vs. 48 (7.75 %) eyes on clinical examination. On the average, optics discs exhibit large size and large cup volume. Topographic evaluation of the optic disc by the means of OCT offers important data and gives way to etiological research of large cupping in the black African. Copyright © 2017 Elsevier Masson SAS.

    The aim of this study is to verify the level of transmission of lymphatic filariasis three years after stopping mass drug treatment in the 7 endemic districts in Togo. The survey was conducted in 2012 in Togo's 7 endemic districts grouped into four evaluation units (EU) using the WHO-recommended transmission assessment survey (TAS) protocol. Children aged 6-7 years were screened for Wuchereria bancofti antigen using the immunochromatographic card (ICT) method. A cluster sampling method was used to select eligible children in schools as the net primary-school enrolment ratio is greater than or equal to 75% in each of the four EUs. The number of children and schools to be selected in each EU, the randomization list for the selection of these children and the critical cut-off number of positive cases not to exceed were automatically generated using the Survey Sample Builder (SSB) tool, (NTD Support Center, Atlanta, Ga, USA). For confirmation, positive cases were subsequently tested for microfilaremia using nocturnal thick blood smear and for filarial antigen using Og4C3 antigen ELISA (TropBio ELISA Kit®, Townsville, Queensland, Australia). An EU is considered to have passed the test successfully (it is assumed that transmission can no longer be sustained), when the number of positive cases is below the critical cut-off number set by the SSB, which is roughly equivalent to 2% prevalence. Of the 1 706 children surveyed in Kpendjal-Tone's EU, 1 549 in Binah-Doufelgou's EU, 1 550 in Kozah's EU and the 1 575 in Amou-Haho's EU, 8 (0.46%), 1 (0.08%), 0 (0.00%) and 4 (0.25%) ICT positive cases respectively were detected. The number of positive ICT tests was well below 18, the critical cut number for each of the 4 EUs. All 13 ICT positive cases tested negative for nocturnal microfilaremia and Og4C3 ELISA. We conclude that all four EU passed the TAS with success, and the transmission of Wuchereria bancrofti is no longer likely to be sustained in the 7 endemic districts in Togo

  15. Energy access in rural Togo: the relevance of the energy kiosk solution

    Solar home systems (SHS) represent today a viable and scalable solution to meet basic energy needs (lighting, mobile phone charging) - the first step of the energy ladder - but are much more limited when it comes to offering productive use of energy. Productive use of energy is however crucial to develop valuable economic activities in off-grid villages. Solar kiosk and mini-grids are two potential solutions to meet these productive energy needs. The main difference lies in the distribution network, which requires both investment and maintenance and thus is expensive. As an example, a $500/customer connection translates into a monthly grid fee equivalent to the monthly cost of a standard solar home system (which includes energy). It is likely that households consumption alone won't be sufficient to ensure the economic profitability of a mini-grid, if the mini-grid developer does not benefit from any public subsidy. Moreover, though mini-grids are usually developed for larger systems, in some cases solar kiosks have the same order of magnitude of installed power capacity as mini-grids (i.e. Ekocenter vs. Powergen RE). In the context of off-grid rural village with very limited energy consumption, start-ups or entrepreneurial projects might prefer to bet on the least capital intensive concept. With a lower nominal CAPEX and more diverse sources of revenues compared to mini-grids, solar kiosks appear as an easier solution to provide access to productive use of energy in the short term. The flexibility of their revenue sources is today a massive advantage of the model. Yet flexibility might also be a weakness as it hinders the firm from choosing a long term position, which is necessary to build a scaled up business model and company. Solar kiosks can progressively evolve in the mid-term towards an independent power producer model; but it can also leverage its last-mile customer proximity to offer a larger array of non-energy products and services. For example, a

    A recent innovation in support of the final segment of the immunization supply chain is licensing certain vaccines for use in a controlled temperature chain (CTC), which allows excursions into ambient temperatures up to 40°C for a specific number of days immediately prior to administration. However, limited evidence exists on CTC economics to inform investments for labeling other eligible vaccines for CTC use. Using data collected during a MenAfriVac™ campaign in Togo, we estimated economic costs for vaccine logistics when using the CTC approach compared to full cold chain logistics (CCL) approach. We conducted the study in Togo's Central Region, where two districts were using the CTC approach and two relied on a fullCCL approach during the MenAfriVac™ campaign. Data to estimate vaccine logistics costs were obtained from primary data collected using costing questionnaires and from financial cost data from campaign microplans. Costs are presented in 2014 US dollars. Average logistics costs per dose were estimated at $0.026±0.032 for facilities using a CTC and $0.029±0.054 for facilities using the fullCCL approach, but the two estimates were not statistically different. However, if the facilities without refrigerators had not used a CTC but had received daily deliveries of vaccines, the average cost per dose would have increased to $0.063 (range $0.007 to $0.33), with larger logistics cost increases occurring for facilities that were far from the district. Using the CTC approach can reduce logistics costs for remote facilities without cold chain infrastructure, which is where CTC is designed to reduce logistical challenges of vaccine distribution.

    Full text: Background: Control of Growth Promotion (CGP) is an activity that can detect early if the child has a developmental problem and investigate the cause and take appropriate decisions to overcome the consequences. In Togo, the goal in 2013 is to weigh at least 80 % of children 0-5 years during the sessions of CGP. What are the levels achieved this goal after the first semester and the problems of malnutrition detected? Method: We conducted a descriptive cross-sectional study data collected in the quarterly reports in two regions of Togo, Lomé - Commune in the South and Central Region in the North. The study involved data from the first semester of 2013 in all districts of the two regions. Database monitoring activities at national level CGP was used. Data from the two regions were separated and analyzed using Excel. Comparison tests of proportions were made using Epi Info 7. Results: Detection rate of nutritional status by the CGP in the first half of 2013 was 29% of the total target of 155,423 children under 5 years in the two regions. This rate was higher for the Central region (33 %) than for Lomé-Commune (26 %). No district has reached half of the goals. Their rates vary from 17.9 % and 18 % respectively for District No. 2 and District No. 4 of Lomé-Commune to 39.7% for the District of Tchaoudjo. The malnutrition rate was 8.8 %. This rate is higher in the Central region (10.9 %) than in Lomé-Commune (6.8 %) with a RR = 1.59, 95% CI = [1.50 to 1.69]. Severe malnutrition was 1.4 %. It is predominant in Lomé-commune (1.7 %) than in the Central region (1.1%) with a RR = 1.55, 95% CI = [1.32 to 1.82]. Conclusion: All districts in the two regions are below the target detection rate in the first half. The CGP has detected cases of moderate and severe malnutrition. To compare that rates with the survey data, the screening tools must be standard and adequate. (author)

    Waste biodegradation has been largely investigated in the literature by using conventional tests like the BMP test and the respirometric test, whereas only few studies deal with the use of leaching tests in combination with biological activity measurements. Consequently, this study used an improved leaching test to evaluate the biodegradability of two deposits of fresh household waste from the city of Kara in Togo. The first deposit came from households in neighborhoods located in the outskirts of the city and the second consisted of fresh waste, mainly composed of business waste and household waste, collected in the urban center and aimed at being deposited in the landfill. A physicochemical characterization of the two deposits completed the leaching test. The biological activity was monitored by measuring O(2) consumption and CO(2) production. pH, DOC/OM, VFA/DOC ratios and the SUVA index was measured in the leaching juice to assess both the state of degradation of the waste in the deposits and the ability of the organic matter to be mobilized quickly and to be easily assimilated by microorganisms. The biodegradability of waste from the city of Kara correlated with their origin even though the physical characteristics of the two deposits studied differed greatly. Copyright © 2012 Elsevier Ltd.

    Personal social networks and their association with the health of older people have been explored, but there are few studies that examined the relationship between the general health of older people living with HIV/AIDS (OPLWHA) and their personal social networks. This exploratory study investigates the characteristics of personal networks among OPLWHA and the relationship between the self-rated health and personal social networks of OPLWHA in Lomé, Togo. Forty-nine OPLWHA were interviewed via an egocentric survey. We examined the composition and size of the networks of OPLWHA. Also, the correlation between networks and self-reported health was examined. Findings show that the OPLWHA had personal social networks that included three types of people: immediate kin, extended kin, and non-kin. Additionally, these networks varied by size. While the mean number of people in the smaller network (people from whom the OPLWHA can borrow an important sum of money) was less than one person (0.55), the mean number of people in the larger network was three (people with whom the OPLWHA enjoy socializing). Furthermore, only the network of people with whom OPLWHA enjoy socializing had a significant positive correlation on the self-rated health of OPLWHA. Consistent with prior research, we found that the mere existence of a network does not imply that the network has a positive correlation with the subject or that the network provides the social support needed to positively influence health. A study of the correlation between social network characteristics and health in the population of older people with HIV/AIDS is important as the number of OPLWHA continues to grow.

    Background The only available vaccine that could be potentially beneficial against mycobacterial diseases contains live attenuated bovine tuberculosis bacillus (Mycobacterium bovis) also called Bacillus Calmette-Guérin (BCG). Even though the BCG vaccine is still widely used, results on its effectiveness in preventing mycobacterial diseases are partially contradictory, especially regarding Buruli Ulcer Disease (BUD). The aim of this case-control study is to evaluate the possible protective effect of BCG vaccination on BUD. Methodology The present study was performed in three different countries and sites where BUD is endemic: in the Democratic Republic of the Congo, Ghana, and Togo from 2010 through 2013. The large study population was comprised of 401 cases with laboratory confirmed BUD and 826 controls, mostly family members or neighbors. Principal Findings After stratification by the three countries, two sexes and four age groups, no significant correlation was found between the presence of BCG scar and BUD status of individuals. Multivariate analysis has shown that the independent variables country (p = 0.31), sex (p = 0.24), age (p = 0.96), and presence of a BCG scar (p = 0.07) did not significantly influence the development of BUD category I or category II/III. Furthermore, the status of BCG vaccination was also not significantly related to duration of BUD or time to healing of lesions. Conclusions In our study, we did not observe significant evidence of a protective effect of routine BCG vaccination on the risk of developing either BUD or severe forms of BUD. Since accurate data on BCG strains used in these three countries were not available, no final conclusion can be drawn on the effectiveness of BCG strain in protecting against BUD. As has been suggested for tuberculosis and leprosy, well-designed prospective studies on different existing BCG vaccine strains are needed also for BUD. PMID:25569674

    As for high-elderly society, Japan is going to face in near future, self dependency without depending on others as far as possible of bed ridden people or people using wheel chair and also including the probable elderly ones is going to be necessary. In Japan, there is so far accumulation of high level mechatronics technology and it is thought that there is possible to develop a system to fulfill such needs. In this system, equipment has deep connection with human being and natural coexistence between the equipment and human being is most necessary. Accordingly, development and practical use of walking practicing machine used for elderly people, walking support system, daily life work support system and so forth are expected by making successful in practice the coexistence functions of high level robot/mechatronics technology and machine/man. However, the study regarding the technology that are common to man and machine, particularly, research of mental characteristics and physical characteristics of human being is still insufficient and further results are expected. 9 refs., 12 figs.

    To avoid economic and technological risks upon initial introduction of distributed new power source technology, methods for reduction in the initial investment burden under the lease system and methods for risk reduction under the insurance system are discussed, and each is evaluated for their applicability to the new technology. Methods for popularizing and enlightening the technology are also discussed using the result of a 'survey for promoting the introduction of new energies' conducted into local autonomies assuming the role of diffusing the new technology into the residential and commercial sectors. Through the review of the current status of initial investment burden reduction methods mainly under the lease system and through some case studies, the applicability of such methods to the new technology is discussed. Similar studies are also made by investigating the current status of risk reduction methods and by conducting case studies, these centering on various kinds of machinery insurance. Questionnaires are sent to local autonomies, who play an important part in the initial introduction into and popularization in the residential and commercial sectors, to learn their consciousness of energy problems and of distributed new power source technology introduction. The result is used to review how popularization and enlightenment activities should be conducted. (NEDO)

    La myasthénie est une pathologie auto-immune acquise rare à l'origine de la déficience de la transmission neuro-musculaire dont la forme juvénile se manifeste souvent par une atteinte oculaire exclusive. Nous rapportons deux cas de myasthénie juvénile oculaire (MJO) au sein d'une même fratrie. il s'agit de deux fillettes XA et XB respectivement âgées de 11 et 9 ans d'origine malienne résidant au Togo, issues d'un mariage consanguin de 1er degré, amenées en consultation d'ophtalmologie, pour une baisse progressive de l'acuité visuelle (AV). XA avait aux deux yeux, une AV à 8/10 et XB, une AV de 3/10 améliorée au trou sténopéïque à 7/10 en faveur d'une amétropie. XA présentait un ptosis bilatéral qui remontait à l'âge de 2 ans avec une action du releveur de la paupière supérieure (RPS) à 7 mm et XB, un ptosis bilatéral remontant à l'âge de 3 ans avec une action du RPS nulle. Pour les deux, le test au glaçon était franchement positif, le signe de Cogan présent avec une parésie oculo motrice sans diplopie. Le dosage des auto-anticorps anti récepteurs de l'acéthylcholine était normal. Le diagnostic de MJO associée à une amétropie a été évoqué. Une correction optique de l'amétropie par des lunettes et un traitement spécifique par la pyridostigmine avait été instaurée mais les patientes ont été perdues de vue. la myasthénie auto-immune avec des manifestations ophtalmologiques inaugurales est rare mais possible chez l'enfant en Afrique subsaharienne où des études sont nécessaires pour y déterminer les éventuelles particularités de la maladie.

    Introduction L’objectif était d’étudier les aspects épidémiologiques, cliniques et évolutifs de l’embolie pulmonaire au CHU Campus de Lomé. Méthodes C’est une étude rétrospective, analytique et descriptive sur une période de 39 mois (1erNovembre 2011- 31 Janvier 2015). Etaient inclus, tous les dossiers des patients hospitalisés dans le service de cardiologie du CHU Campus pour une EP. Résultats La prévalence de l’EP était de 3,1%. Le sex ratio femme/homme était de 2,2. L’âge moyen des patients était de 52,7 ± 14,4 ans. Les facteurs de risque de MTEV étaient dominés par: l’obésité (54,9%), l’alitement (25,5%) et le long voyage (17,6%). Les principaux symptômes étaient: dyspnée (98,0%), douleur thoracique (78,4%) et toux (60,8%). Le score de Wells était élevé dans 29,4%. L’ECG notait: tachycardie (78,4%), HVD (49,0%), aspect S1Q3T3 (47,1%) et bloc droit (39,2%). L’échodoppler cardiaque transthoracique montrait une dilatation cavitaire droite et thrombus intra ventriculaire droit dans 5,6%. L’angioscanner thoracique était normal dans 9,8% et objectivait un embole dans 82,4%. Le traitement était fait d’HBPM à dose curative avec relais par un AVK. Une thrombolyse était effectuée chez 8 malades. L’évolution était favorable dans 86,3%. Le taux de létalité était de 13,7%. Conclusion La prévalence de l’EP est relativement faible chez nous mais probablement sous estimée. L’EP pose un problème thérapeutique au Togo à cause du coût élevé des examens complémentaires et de la thrombolyse. La prévention reste donc l’arme efficace. PMID:28904659

    This study aims to evaluate the performance of a few biochemistry analysis and make recommendations to the place of the stakeholders. It is a cross-sectional study conducted between the October 1(st), 2012 and the July 31, 2013 bearing on the results of 5 common examinations of clinical biochemistry, provided by 11 laboratories volunteers opening in the public and private sectors. These laboratories have analysed during the 3 cycles, 2 levels (medium and high) of serum concentration of urea, glucose, creatinine and serum aminotransferases. The performance of laboratories have been determined from the acceptable limits corresponding to the limits of total errors, defined by the French Society of Clinical Biology (SFBC). A system of internal quality control is implemented by all laboratories and 45% of them participated in international programs of external quality assessment (EQA). The rate of acceptable results for the entire study was of 69%. There was a significant difference (plaboratories engaged in a quality approach and the group with default implementation of the quality approach. Also a significant difference was observed between the laboratories of the central level and those of the peripheral level of our health system (plaboratories remains relatively unsatisfactory. It is important that the Ministry of Health put in place a national program of EQA with mandatory participation.

    Mass drug administration (MDA) of ivermectin has become the main intervention to control onchocerciasis or "river blindness". In Togo, after many years of MDA, Onchocerca volvulus infection has declined dramatically, and elimination appears achievable, but in certain river basins the current situation remains unknown. We have conducted parasitological, serological, ophthalmological, and entomological assessments in northern and central Togo within the river basins of Ôti, Kéran and Mô. Examinations were completed in 1,455 participants from 11 onchocerciasis sentinel villages, and O. volvulus transmission by Simulium damnosum sensu lato (s.l.) was evaluated. In children (aged 1-10 years), the prevalence of microfilariae (Mf) was 2.3% and in adults it ranged from 5.1 to 13.3%. Positive IgG4 responses to O. volvulus adult (crude) worm antigen (OvAg) and the recombinant Ov16 antigen were in all-ages 48.7% and 34.4%, and 29.1% and 14.9% in children, respectively. In the river basin villages of Kéran, Mô and Ôti, the IgG4 seroprevalences to OvAg in children were 51.7%, 23.5% and 12.7%, respectively, and to the Ov16 antigen 33.3% (Kéran) and 5.2% (Ôti). Onchocerciasis ocular lesions (punctate keratitis, evolving iridocyclitis and chorioretinitis) were observed in children and young adults. O. volvulus-specific DNA (Ov150) was detected by poolscreen in vector samples collected from Tchitchira/Kéran(22.8%), Bouzalo/Mô(11.3%), Baghan/Mô(2.9%) and Pancerys/Ôti(4.9%); prevalences of O. volvulus infection in S. damnosum s.l. were, respectively, 1%, 0.5%, 0.1% and 0.2%. In the northern and central river basins in Togo, interruption of O. volvulus transmission has not yet been attained. Patent O. volvulus infections, positive antibody responses, progressive ocular onchocerciasis were diagnosed, and parasite transmission by S. damnosum s.l. occurred close to the survey locations. Future interventions may require approaches selectively targeted to non-complying endemic

    The standard methods for regression analyses of clustered riverine larval habitat data of Simulium damnosum s.l. a major black-fly vector of Onchoceriasis, postulate models relating observational ecological-sampled parameter estimators to prolific habitats without accounting for residual intra-cluster error correlation effects. Generally, this correlation comes from two sources: (1) the design of the random effects and their assumed covariance from the multiple levels within the regression model; and, (2) the correlation structure of the residuals. Unfortunately, inconspicuous errors in residual intra-cluster correlation estimates can overstate precision in forecasted S.damnosum s.l. riverine larval habitat explanatory attributes regardless how they are treated (e.g., independent, autoregressive, Toeplitz, etc). In this research, the geographical locations for multiple riverine-based S. damnosum s.l. larval ecosystem habitats sampled from 2 pre-established epidemiological sites in Togo were identified and recorded from July 2009 to June 2010. Initially the data was aggregated into proc genmod. An agglomerative hierarchical residual cluster-based analysis was then performed. The sampled clustered study site data was then analyzed for statistical correlations using Monthly Biting Rates (MBR). Euclidean distance measurements and terrain-related geomorphological statistics were then generated in ArcGIS. A digital overlay was then performed also in ArcGIS using the georeferenced ground coordinates of high and low density clusters stratified by Annual Biting Rates (ABR). This data was overlain onto multitemporal sub-meter pixel resolution satellite data (i.e., QuickBird 0.61m wavbands ). Orthogonal spatial filter eigenvectors were then generated in SAS/GIS. Univariate and non-linear regression-based models (i.e., Logistic, Poisson and Negative Binomial) were also employed to determine probability distributions and to identify statistically significant parameter

    Full Text Available The wild edible mushrooms are often used by people who live around the PNFM of Togo. To know better the ecto-mycorrhizal taxa used and to document the endogenous knowledge, surveys on ethno-mycological knowledge were conducted in the city of Bassar from the ethnic group of Bassar and in the village of Hezoudè from Kabyè ethnic group. During this study, based on semi-structural ethno-mycological survey, 432 people aged 10 to 80 years from the Kabyè and Bassar areas are interviewed via focus group and/or individual interviews. After ethno-mycological investigations, 23 taxa are known as edible. The ethno-mycological indices such as Use Value (UV, Index of Fisher (p and Index of Importance Value (IVI are calculated to test the knowledge on the different use of mushrooms by the two ethnic groups. The study revealed that there is no significant difference regarding the number of consumed taxa for each ethnic group and the levels of their traditional knowledge. The study also showed that the traditional ethno-mycological knowledge of the population varies according to age, the ethnical group and sex. The elders are proven to be the holders of the best mycological knowledge. The most ecto-mycorrhizal mushrooms consumed are Amanita loosii, Russula oleifera and Cantharellus congolensis. These preliminary data indicate that the ecto-mycorrhizal mushrooms and their uses are well known by the people who live around the PNFM.

    To reduce SOx with coal utilization, a desulfurizer is introduced in Thailand as diffusion activities in the demonstration program. The purpose is to reduce the environmental pollutants. For this desulfurizer, lime mud mainly composed of lime stone is used as an absorber. SO2 in the flue gas is absorbed by the slurry of lime mud, to form calcium sulfite. The calcium sulfite blown in the bottom of recycling tank is oxidized by oxygen in the air, to form gypsum. The gypsum is recovered as a by-product. In this fiscal year, a feeder of lime stone, spray nozzles, and various analysis apparatuses were supplied. Supervisors for electric instrumentation/control were also dispatched as well as for main body construction, to carry out the instrumentation setting works, check of sequences, and adjustment of apparatuses. After the test operation, supervisors for the demonstration operation were dispatched up to March 1998, to conduct the cooperation works between Japan and Thailand sides. Thus, successful and successive demonstration operation was confirmed. 21 figs., 6 tabs.

    Introduction Une campagne de vaccination contre la méningite A avec le vaccin MenAfriVac a été organisée dans les quatre régions septentrionales du Togo du 28 novembre au 07 décembre 2014. L'approche CTC a été utilisée pour la première fois à une grande échelle pour la campagne de vaccination dans dix districts sanitaires du Togo. L'objectif de cette étude était d'estimer la couverture vaccinale et, de déterminer l'effet de l'utilisation de la Chaîne à Température Contrôlée (CTC) sur ces couvertures vaccinales. Méthodes L'enquête s'est déroulée du 9 au 14 mars 2015, soit environ 3 mois après la fin de la campagne de vaccination dans ces quatre régions. Le sondage en grappe à deux degrés stratifiés selon les régions a été utilisé. Dans 10 districts, le Togo a fait le choix d'utiliser le vaccin MenAfriVac en CTC. Résultats Au total, 2707 ménages ont été enquêtés et 9082 personnes âgées de 1 à 29 ans ont été interviewées. L'âge moyen des personnes enquêtées était de 11,8±7,7 ans et le sex-ratio (H/F) de 1,01. Le nombre moyen de personnes par ménage était de 5,7 et celui des personnes de 1 à 29 ans ciblées par la campagne était de 3,4. Sur les 9082 personnes enquêtées, 8889 (98%) étaient vaccinées. En analyse multivariée, les facteurs associés à la couverture vaccinale avec le MenAfrivac étaient la résidence dans la zone au moment de la campagne (aOR = 4,52 ; 95%IC = [4.07 - 4.97]) et le fait d'être informé de la campagne avant son démarrage (aOR=2,42 ; 95%IC = [2.05 - 2.80]). Par contre, la couverture vaccinale n'était pas différente selon la zone ayant utilisé l'approche CTC ou non (aOR=0,09 ; 95%IC = [-0,27-0,45]). Deux cent sept personnes interrogées (2,3%) ont déclaré avoir eu une Manifestation Adverse Post Immunisation (MAPI) après l'administration du vaccin. Il s'agissait surtout de MAPI mineures à type de fièvre, d'abcès et de gonflement au point d'injection. Conclusion Les r

    To evaluate geothermal reservoirs in the initial stage of development, to keep stable output in service operation, and to develop a technology effective for extraction from peripheral reservoirs, study was made on a reservoir variation prediction technique, in particular, a modeling support technique. This paper describes the result in fiscal 1997. Underground temperature estimation technique using homogenization temperatures of fluid inclusions among core fault system measurement systems was applied to Wasabizawa field. The effect of stretching is important to estimate reservoir temperatures, and use of a minimum homogenization temperature of fluid inclusions in quartz was suitable. Even in the case of no quartz in hydrothermal veins, measured data of quartz (secondary fluid inclusion) in parent rocks adjacent to hydrothermal veins well agreed with measured temperature data. The developmental possibility of a new modeling support technique was confirmed enough through collection of documents and information. Based on the result, measurement equipment suitable for R and D was selected, and a measurement system was established through preliminary experiments. 39 refs., 35 figs., 6 tabs.

    Full Text Available Contexte: L’anémie est un problème de santé publique dans le monde entier, et notamment dans les pays en développement. Elle a des répercussions majeures sur la santé et sur ledéveloppement économique et social d’un pays. La prise en charge des patients anémiés étant nécessaire, il faut un diagnostic biologique précis, et donc un dosage du taux d’hémoglobine par des méthodes fiables. Objectif: Évaluer les performances diagnostiques du test Hemocue Hb201+®. Méthodes: Étude comparative de la mesure du taux d’hémoglobine à partir du photomètre Hemocue Hb 201+® et d’analyseurs d’hématologie chez 213 enfants de 6 à 59 mois souffrant d’un paludisme simple; la détermination du taux d’hémoglobine par les analyseurs est retenue comme méthode de référence pour évaluer Hemocue Hb201+®. Résultats: 72.8% des valeurs obtenues par Hemocue Hb201+® étaient à ±1 g/dl de celles de la méthode de référence. Le coefficient de corrélation de Pearson était de 0.80. La prévalence de l’anémie était de 79.3% pour la méthode de référence et de 77.9% pour Hemocue Hb201+®. La sensibilité et la spécificité de l’analyseur Hemocue Hb201+® étaient respectivement de 95.1% et de 65.3%. Conclusion: Les résultats de l’étude ont montré que le test Hemocue Hb201+® présentait une bonne sensibilité, une spécificité moyenne et une exactitude moyenne dans le diagnostic del’anémie et dans le dosage de l’hémoglobine.

    The study is carried out on 410 samples of gossan, siderite and country rocks of the Pagala area, on which 28 major, minor and trace elements and 6 rare earth element (La, Ce, Eu, Yb,Lu, Y) contents were determined. Using a multivariate statistical study, three geochemical phases were discovered. The first one corresponds to a quartz and mica phase of the residual country rocks (Si, Al, Na, K, Ti, Zr, Nb). The second one, corresponding to gossanous iron oxy-hydroxides (Fe, Mn, Zn, Co, LOI and HREE), is interpreted as resulting from hydrothermal enrichments. The third one, shown as another gossanous phase and rarely understood mineralogically (P, Ca, Sr, Cu, Sc and LREE), is probably linked with the phosphatic formations of the area. The projection of the three facies in a system of orthogonal axes, F1 and F2 supports the assumption that the massive siderite represents the protore of cascade gossan (Togbé et al., 1993). This can be applied to all gossans in the area.

    Full Text Available A nonlinear robust control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving nominal system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear robust control strategy is developed that robustly stabilizes a given nonlinear system over a prescribed range of system uncertainty by robustly stabilizing a collection of nonlinear controlled uncertain subsystems. The robust switching nonlinear controller architecture is designed based on a generalized (lower semicontinuous Lyapunov function obtained by minimizing a potential function over a given switching set induced by the parameterized nominal system equilibria. The proposed framework robustly stabilizes a compact positively invariant set of a given nonlinear uncertain dynamical system with structured parametric uncertainty. Finally, the efficacy of the proposed approach is demonstrated on a jet engine propulsion control problem with uncertain pressure-flow map data.

Thus, he secured his third five-year term, consolidating the autocratic grip of the Gnassingbé-clan and his followers, who had been in power since 1967. In view of the absolute majority of the ruling party, its inclination for meaningful constitutional and electoral reforms that would have been required for free and fair elections was further reduced. The reforms were postponed open-endedly....

    Anterior traumatic dislocations of the hip are much less common than posterior dislocations. To date, 14 cases of open anterior dislocation of the hip associated with such injuries, acetabular and femoral head fractures and femoral vascular and nerve damage have been reported. We present a case of a 23-year-old male who sustained open anterior dislocation of the hip with ipsilateral fracture of the greater trochanter after an accident on the public highway. Additional lesions included an iliac wing fracture and a perineal wound. We report this case because of the rarity and seriousness of this injury due to its progressive complications and difficulties related to its management, which are typical to a developing country like ours.

    Full Text Available Suppose S={{Xnj,   j=1,2,…,kn}} is an infinitesimal system of random variables whose centered sums converge in law to a (necessarily infinitely divisible distribution with Levy representation determined by the triple (γ,σ2,M. If {Yj,   j=1,2,…} are independent indentically distributed random variables independent of S, then the system S′={{YjXnj,j=1,2,…,kn}} is obtained by randomizing the scale parameters in S according to the distribution of Y1. We give sufficient conditions on the distribution of Y in terms of an index of convergence of S, to insure that centered sums from S′ be convergent. If such sums converge to a distribution determined by (γ′,(σ′2,Λ, then the exact relationship between (γ,σ2,M and (γ′,(σ′2,Λ is established. Also investigated is when limit distributions from S and S′ are of the same type, and conditions insuring products of random variables belong to the domain of attraction of a stable law.

    Considering integrated hull and piping design in shipbuilding industry as a good example for concurrent engineering (CE), discussions were given on a computer aided method to perform integrated hull and piping design smoothly. When CE aiding by means of a computer is considered, it is important to discuss a method for information management not only for `utilization of product models`, but also for `maintaining consistency between items of product information` and `concurrent utilization and production of product information` in concurrent designs. For the CE aided information management, utilization and production of the product information is effective if restrictive relationship between items of product information, and design functions are made clear. Definitions were given on the restrictive relationship between items of product information and `restrictive relationship information` that has `decision/provisional decision`, `date and time`, `designer` and `design functions`. Furthermore, `comprehensive relationship between items of product information` that can be produced from the restrictive relationship information was defined as a `restrictive network`. Utilizing the restrictive relationship between items of product information for CE aiding is effective. 9 refs., 14 figs.

    The aim of this study was to evaluate the prevalence of the major microorganisms causing vaginal infections in pregnant women consulting at the Regional Hospital of Sokodé and to assess their sensitivity to antibiotics. This prospective study took place from June 2010 through August 2011 and included 302 pregnant women from whom a sample was taken by a vaginal swab. Samples were processed for parasitic, bacterial, and fungal agents, by microscopic examination and culture. We isolated 273 germs, alone or in association in 221 women. These germs were distributed as follows: Gardnerella vaginalis (55.31%), Candida spp (30.77%), Staphylococcus aureus (5.49%), Enterobacteriaceae (4.40%), Trichomonas vaginalis (3.66%) and Mobiluncus spp (0.37%). No Streptococcus strain was isolated during the study. Over 40% of women had bacterial vaginosis and 23.08% of them were coinfected. The occurrence of coinfection was statistically influenced by the stage of pregnancy (P = 0.05). The susceptibility tests revealed that S. aureus developed a strong resistance to aminopenicillins (66.67%) and cephalosporins (>44.44%), while Enterobacteriaceae was resistant to cephalosporins and quinolones. (16.67%). This study showed that pregnant women in Sokode are still exposed to vaginal infection, caused mostly by G. vaginalis and Candida species. These results underline the need for at least one vaginal swab culture for each woman during pregnancy.

    To evaluate the hepatic and obstetric complications in pregnant women with cirrhosis. We report the cases of four pregnant women with cirrhosis treated in the gastroenterology and obstetrics-gynecology departments of the Lome Campus University Teaching Hospital between 2013 and 2015. The women's mean age was 32 years. Three were in the first trimester of pregnancy. Almost all had signs of advanced cirrhosis, including ascites (50%), lower-limb edema (75%), and jaundice (25%). All (100%) had liver failure and anemia. Cirrhosis was due to hepatitis virus B infection for 3 women. All had singleton pregnancies. Two mothers died; fetal outcome included one fetal loss and one stillbirth. This study shows the high risk associated with the combination of pregnancy and cirrhosis. Prognosis is poor for both mother and fetus.

    Full Text Available Background: The aim of this study was to evaluate pain management in paediatric surgery at Sylvanus Olympio University Teaching Hospital, Lome. Patients and Methods: A prospective descriptive study was conducted in the Department of Anaesthesiology and Intensive Care at Sylvanus Olympio teaching hospital from 1 January to 30 June 2012. Data collected include: demography, type of surgery, American Society of Anaesthesiologists (ASA classification, anaesthetic protocol, analgesia technique, post-operative complications and cost of analgesia. Results: The study includes 106 post-operative children. Abdominal surgery was performed in 41.5% and orthopaedic surgery in 31.1%. A total of 75% of patients were classified ASA 1. General anaesthesia (GA was performed in 88%. Anaesthetists supervised post-operative care in 21.7% cases. Multimodal analgesia was used in every case and 12% of patients received a regional block. The most frequently unwanted effects of analgesics used were nausea and/or vomiting in 12.3%. At H24, child under 7 years have more pain assessment than those from 7 to 15 years (46% vs 24% and this difference was statistically significant (chi-square = 4.7598; P = 0.0291 < 0.05. The average cost of peri-operative analgesia under loco regional analgesia (LRA versus GA during the first 48 h post-operative was US $23 versus $46. Conclusion: Our study showed that post-operative pain management in paediatric surgery is often not well controlled and paediatric loco regional analgesia technique is under practiced in sub Saharan Africa.

    The medicine dissertation is often the last step of a physician's medical studies. Long considered a rite of passage, it is now regarded as a scientific work deserving attention from the national and international scientific community. The objectives of this study were to document the means by which dissertations at the University of Lomé Medical School are diffused and to determine their impact on the scientific production of medical school faculty. This cross-sectional study included all dissertations in medicine at the University of Lomé from 1993 through 2002. We interviewed dissertation supervisors and co-supervisors (questionnaire-structured interviews) and consulted the Medline and CNRS/PASCAL databases, scientific communication registers and local journals to collect information. During this period, 240 dissertations were defended at the University of Lomé medical school. More than half came from the departments of medicine (n=85, 35.4%), surgery (n=57, 23.7%) and paediatrics (n=51, 22.5%). The majority dealt with epidemiological (47 %) and clinical (35.8 %) themes, and only a small minority concerned topics in microbiology and biochemistry (7.5 %). Ninety-nine dissertations (41 %) were published: 54 (22.5%) in indexed journals and 45 (18.5 %) in non-indexed journals; 130 (54%) were delivered as papers or posters at scientific meetings. The distribution of published dissertations according to department showed that the departments of paediatrics (51.3 %), medicine (21.2 %) and surgery (21 %) had the best rates of publication in indexed journals, compared with obstetrics and gynaecology (4 %) and basic science (13.8 %) departments. During the study period, faculty at the University of Lomé medical school published 264 articles in indexed journals: dissertations accounted for only 20.4 %. Dissertations made up a higher proportion of publications in the paediatrics department (32.2 %) than in surgery (20.7 %), medicine (19.8 %), basis sciences (14 %) or obstetrics and gynaecology (3.6 %). Our study shows that the proportion of published dissertations remains small and is even smaller if we consider only those published in indexed journals (22.5 %). Dissertations also account for an insignificant proportion of the publications by medical school faculty. This raises the question of the scientific interest that the faculty accord to these dissertations.

    The studied area is straddling the West-African Craton and Nigerian-Beninian panafrican mobile plate. From west to east, it is composed of three large petrostructural sets which show specific gravity characteristics: the Volta Basin domain, constituted of sedimentary formations lying in a major discordance on the West-African Craton crystalline basement; it exhibits positive gravity anomalies probably linked with basic magmatic intrusions met in the basin. Next, one medial set, corresponding to the external structural unit domain of the Dahomeyid range; composed of epi- to mesozonal rocks, it shows large negative anomaly panels very likely in close relation with the tectonic overload. Finally, one eastern set, comprising gneisso-migmatitic internal units of the Nigerian-Beninian plate western border; it mainly outlines positive anomalies which seem to be in connection with granulitic and basic complexes encountered in places inside this area. This set includes the suture zone. We mention in these three sets numerous gravity discontinuities which testify to the great structural complexity of the region. However, this complexity is frequently concealed or attenuated by counterbalance and smoothing phenomena. This gravity complexity increases from north to south, and is interpreted as the sign of a rise of the southern part deep zones of this sector during the panafrican event. Moreover, this complexity also might testify to an aggregation of panafrican mobile plate compartments. (author). 33 refs, 12 figs

    A method for determining part re-use and recycling strategy in product design is considered for optimal design of total product life cycle based on the concept of Right Quality Products. For this purpose, it is important to be able to estimate part deterioration status under various product usage conditions. For supporting product designers' decision making about the product life cycle in preliminary design phase, the deterioration estimation is not required to be very exact, but to generate every possible deterioration modes qualitatively. Then, based on these deterioration modes, functional behaviour of target products is simulated, and possible product failure modes can be generated. By utilizing the FMEA (Failure Mode and Effect Analysis) method, the effects of failure modes are evaluated, and the results are fed back to product designers for confirming their design in terms of total product life cycle optimization. A basic methodology is considered, and case study has been done for a mechanical assembly of a one-time use camera. The assembly consists of injection molded parts. Various CAE methods have been used for predicting possible part failures due to initial residual stress, warp, fatigue, creep, and wear. Then kinematic and dynamic analysis of mechanical assembly has been done for detecting the effect of part deterioration on mechanism movements. Several critical failure modes have been detected, and the effects of those failures have been checked by the FMEA method. (NEDO)

    To evaluate transfusion practice in the hepatogastroenterology department of the Campus Teaching Hospital of Lomé. This is a respective, descriptive and analytical study conducted from January 1 to December 31, 2013 on cases of in-patients' observation in the department. The cases of in-patients of more than 15 years old, having benefited from a blood transfusion were included. During the study period, 849 patients were admitted; 136 were transfused, or blood transfusion rate of 16.02%. The average age of patients was of 48.25 years with extremes of 15 and 90 years. The most transfused rhesus blood group was O positive (36.76%). Red blood cell was the most frequently used blood product (94.12%). The transfusion was performed in 58.82% of cases as a matter of emergency. Gastrointestinal bleeding were the main indications (55.88%). The average pre-transfusion hemoglobinemia was 6.51 g/dL±1.67. The average post-transfusion hemoglobinemia was 8.95 g/dL±1.75. Liver disease (cirrhosis and hepatocellular carcinoma) were the main diagnosis associated with blood transfusion (44.85%). The quantity of blood to be transfused was not calculated in 100% of cases. In 11.03% of cases, the compatibility test has not been done in the laboratory. Incidents during blood transfusion were noted in 5 cases. Blood transfusion is frequent in the department. There is a good observance of blood transfusion safety regulations. However, its practice remains to be improved. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    An expert system is a computer system for inferring knowledge from a knowledge base, typically by using a set of inference rules. When the concept of expert systems was introduced at Stanford University in the early 1970s, the knowledge base was an unstructured set of facts. Today the knowledge...... base of expert systems is often given in terms of an ontology, extracted and built from various data sources by employing natural language-processing and statistics. To emphasize such capabilities, the term “expert” is now often replaced by “cognitive,” “knowledge,” “knowledge-based,” or “intelligent......” system. With very few exceptions, general-purpose expert systems have failed to emerge so far. However, expert systems are applied in specialized domains, particularly in healthcare. The increasing availability of large quantities of data to organizations today provides a valuable opportunity...

    factor and the fixation index of the soils were variable. Application of water-soluble P as TSP increased both the C P and E 1 values of all the soils above the critical levels. Togo PR was least effective among the fertilizers tested for all soil soils, except in Boi soil. Acidulation of Togo PR (Togo PAPR-50%) was an effective means to increase its agronomic effectiveness. Direct application of natural Togo PR would be only feasible in the Boi soil series as reflected by its high Pdff% value in soil solution. Incubation with the P fertilizers caused an increase in the soil pH and a decline in the effectiveness of the applied P fertilizers, irrespective of the soil and the fertilizer utilized. Based upon the results of the greenhouse pot experiment, the relative crop response index (RCRI) in terms of increasing dry matter yield and P uptake followed the order of TSP > PAPR = Mali PR >Togo PR = Control. Both the laboratory index, Pdff% in soil solution derived from the isotopic method and the RCRI values obtained from the pot experiment produced similar results in ranking the P fertilizers tested according to their agronomic effectiveness. The isotopic kinetic method may be considered as an alternative to both greenhouse and field methods in the evaluation of agronomic effectiveness of P fertilizers in tropical acid soils when it offers comparative advantages in assessing the soil P status and its changes. But trained staff and adequate laboratory facilities are needed to perform this technique. Also the method can be used as a reference for comparison purposes as in this case. Further research is needed to assess the overall agronomic effectiveness (immediate and residual effects) of PR sources in predominant cropping systems of this region of Ghana. (author)

    The paper reviews the experimental and theoretical studies carried out on multicomponent alkali metal systems. Solid-liquid phase equilibria studies are mainly concerned with the systems Na-K-Rb and Na-K-Cs, and data on the liquidus temperatures in these systems are presented. The thermodynamic properties of the ternary Na-K-Cs eutectic system have been determined experimentally, and the enthalpy, heat capacity and excess functions of the alloy are given. An analysis of calculational methods used in determining thermodynamic functions of ternary liquid metals systems is described. Finally, data are tabulated for the density, compressibility, saturated vapour pressure, viscosity and thermal conductivity of the ternary Na-K-Cs eutectic system. (UK)

    Technology has now progressed to the point that intelligent systems are replacing humans in the decision making processes as well as aiding in the solution of very complex problems. In many cases intelligent systems are already outperforming human activities. Artificial neural networks are not only capable of learning how to classify patterns, such images or sequence of events, but they can also effectively model complex nonlinear systems. Their ability to classify sequences of events is probably more popular in industrial applications where there is an inherent need to model nonlinear system

    Yellow fever (YF) remains a public health problem in Africa. In 2007 and 2008, Togo, Senegal, Mali and Burkina Faso became the first countries to implement mass YF immunization campaigns within the framework of the Yellow Fever Initiative. The goal of this initiative led by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) with the support of The Global Alliance for Vaccines and Immunization (GAVI) is to organize mass YF immunization campaigns in 12 African countries at high risk forYF transmission between 2006 and 2013. A total of 290 million USD have been allocated for vaccination of 180 million people with the highly effective attenuated 17DYF vaccine. Working in partnership with the WHO, the 12 member states are to identify and target high risk areas with the dual aim of preventing epidemics and increasing immunization coverage. Surveillance of adverse events following immunization (AEFI) is a mandatory component for organization of these campaigns. Purpose. The purpose of this article is to describe the AEFI surveillance system implemented in Burkina Faso in 2008. Methods. The strategy used in Burkina Faso was based on a combination of regular passive surveillance and active surveillance. General guidelines and related operational processes were established including reporting forms, investigation forms, and procedures for collection, storage and transport of biological specimens. Classification of cases was based on clearly defined criteria. Any patient meeting the defined criteria and requiring hospitalization was considered as a serious case. In addition to case definition criteria, serious cases were tracked according to presented signs and symptoms using a line-listing form at two university hospital centers in Ouagadougou and one regional hospital center. Emergency room admission records and patient charts were examined during the surveillance period (30 days after the end of the immunization campaign) and on

  17. Anticipatory systems as linguistic systems

    Science.gov (United States)

    Ekdahl, Bertil

    2000-05-01

    The idea of system is well established although not well defined. What makes up a system depends on the observer. Thinking in terms of systems is only a convenient way to conceptualize organizations, natural or artificial, that show coherent properties. Among all properties, which can be ascribed to systems, one property seems to be more outstanding than others, namely that of being anticipatory. In nature, anticipatory properties are found only in living organizations. In this way it can be said to separate non-living systems from living because there is no indication that any natural phenomenon occurring in systems where there is no indication of life is anticipatory. The characteristic of living systems is that they are exposed to the evolution contrary to causal systems that do not undergo changes due to the influence of the environment. Causal systems are related to the past in such a way that subsequent situations can be calculated from knowledge of past situations. In causal systems the past is the cause of the present and there is no reference to the future as a determining agent, contrary to anticipatory systems where expectations are the cause of the present action. Since anticipatory properties are characteristic of living systems, this property, as all other properties in living systems, is a result of the evolution and can be found in plants as well as in animals. Thus, it is not only tied to consciousness but is found at a more basic level, i.e., in the interplay between genotype and phenotype. Anticipation is part of the genetic language in such a way that appropriate actions, for events in the anticipatory systems environment, are inscribed in the genes. Anticipatory behavior, as a result of the interpretation of the genetic language, has been selected by the evolution. In this paper anticipatory systems are regarded as linguistic systems and I argue that as such anticipation cannot be fragmented but must be holistically studied. This has the

    As a part of the research and development regarding characterisation of deep geological environment, the GEOMASS (GEOLOGICAL MODELLING ANALYSIS AND SIMULATION SOFTWARE) system has been developed by the Japan Atomic Energy Agency in order to carry out geological and hydrogeological modelling and groundwater flow simulation and so on. The GEOMASS system integrates a commercial geological interpretation system (EarthVision), which is used for geological modelling and visualisation, with a proprietary code for groundwater flow (FracAffinity). This integrated system allows users to make rapid improvement of models as data increases. Also, it is possible to perform more realistic groundwater flow simulation due to the capability of modelling the rock mass as a continuum with discrete hydro-structural features in the rock mass. This paper consists of 'Overview of GEOMASS system', FracAffinity Theoretical Background' and 'FracAffinity User Guide' and is edited as a GEOMASS system manual. 'Overview of GEOMASS system' describes the outline of this system. 'FracAffinity Theoretical Background' describes the information of technical background of FracAffinity software. FracAffinity User Guide' describes the structure of the FracAffinity input files, the usage of FracAffinity Interface and flow-solver. Updating of the FracAffinity has been continued as needed and FracAffinity version3.3 is the latest version at present (July 2008). (author)

    In the wake of the oil shock in 1973, the need for developing more effective energy systems has been mounting. The dominant views and topics for power generation systems in terms of scale merit shifted from the advocacy of centralization/scaling-up of facilities to the soft energy path theory insisting on the efficiency of dispersed small-scale plants, followed by the recent holonic path theory which maintains that large and small scale plants should be centralized or dispersed in an optimum manner. At the same time, an autonomous-type system concept has emerged which points out that the energy systems can be operated efficiently through mutual coordination and cooperation between the suppliers and users to find a balance point that meets the market principle, while abolishing the conventional suppliers-governed system. As a result, the load management system based on time-of-use pricing or adaptive pricing is expected to be adopted widely in near future. All these new theories are aimed at developing flexible and reasonable system structures that can be adapted to the changing circumstances. (4 figs, 17 refs)

    Several ring systems (Saturn systems) have been studied using DFT methods that include dispersion effects. Comparison with X-ray structures are made with three systems, and the agreement is quite good. Binding enthalpies and binding free energies in dichloromethane and toluene have been computed. The effect of an encapsulated lithium cation is accessed by comparing C60 @(C6 H4 )10 and [Li@C60 @(C6 H4 )10 ](+). The [Li@C60 ](+) cation is a much better acceptor than C60 which leads to greater donor-acceptor interactions and larger charge transfer from the ring to [Li@C60 ](+). © 2015 Wiley Periodicals, Inc.

    This monograph presents a systematic analysis of bubble system mathematics, using the mechanics of two-phase systems in non-equilibrium as the scope of analysis. The author introduces the thermodynamic foundations of bubble systems, ranging from the fundamental starting points to current research challenges. This book addresses a range of topics, including description methods of multi-phase systems, boundary and initial conditions as well as coupling requirements at the phase boundary. Moreover, it presents a detailed study of the basic problems of bubble dynamics in a liquid mass: growth (dynamically and thermally controlled), collapse, bubble pulsations, bubble rise and breakup. Special emphasis is placed on bubble dynamics in turbulent flows. The analysis results are used to write integral equations governing the rate of vapor generation (condensation) in non-equilibrium flows, thus creating a basis for solving a number of practical problems. This book is the first to present a comprehensive theory of boil...

    Full Text Available Two strategies towards the realization of nanotechnology have been presented, i.e., top-down and bottom up. The former one is mainly based on nanofabrication and includes technologies such as nano-lithography, nano-imprint, and etching. Presently, they are still 2D fabrication processes with low resolution. The later one is an assembly-based technique. At present, it includes such items as self-assembly, dip-pen lithography, and directed self-assembly. These techniques can generate regular nano patterns in large scales. To fabricate 3D complex nano devices there are still no effective ways by so far. Here we show our effort on the development of a nano laboratory, a prototype nanomanufacturing system, based on nanorobotic manipulations. In which, we take a hybrid strategy as shown in Fig. 1. In this system, nano fabrication and nano assembly can be performed in an arbitrary order to construct nano building blocks and finally nano devices. The most important feature in this system is that the products can be fed back into the system to shrink the system part by part leading to nanorobots. Property characterization can be performed in each intermediate process. Due to the nanorobotic manipulation system, dynamic measurement can be performed rather than conventional static observations.

    Full Text Available The global availability of communication services makes it possible to interconnect independently developed systems, called constituent systems, to provide new synergistic services and more efficient economic processes. The characteristics of these new Systems-of-Systems are qualitatively different from the classic monolithic systems. In the first part of this presentation we elaborate on these differences, particularly with respect to the autonomy of the constituent systems, to dependability, continuous evolution, and emergence. In the second part we look at a SoS from the point of view of cognitive complexity. Cognitive complexity is seen as a relation between a model of an SoS and the observer. In order to understand the behavior of a large SoS we have to generate models of adequate simplicity, i.e, of a cognitive complexity that can be handled by the limited capabilities of the human mind. We will discuss the importance of properly specifying and placing the relied-upon message interfaces between the constituent systems that form an open SoS and discuss simplification strategies that help to reduce the cognitive complexity.

    The Systems Studies Activity had two objectives: (1) to investigate nontechnical barriers to the deployment of biomass production and supply systems and (2) to enhance and extend existing systems models of bioenergy supply and use. For the first objective, the Activity focused on existing bioenergy markets. Four projects were undertaken: a comparative analysis of bioenergy in Sweden and Austria; a one-day workshop on nontechnical barriers jointly supported by the Production Systems Activity; the development and testing of a framework for analyzing barriers and drivers to bioenergy markets; and surveys of wood pellet users in Sweden, Austria and the US. For the second objective, two projects were undertaken. First, the Activity worked with the Integrated BioEnergy Systems (TBS) Activity of TEA Bioenergy Task XIII to enhance the BioEnergy Assessment Model (BEAM). This model is documented in the final report of the IBS Activity. The Systems Studies Activity contributed to enhancing the feedstock portion of the model by developing a coherent set of willow, poplar, and switchgrass production modules relevant to both the US and the UK. The Activity also developed a pretreatment module for switchgrass. Second, the Activity sponsored a three-day workshop on modeling bioenergy systems with the objectives of providing an overview of the types of models used to evaluate bioenergy and promoting communication among bioenergy modelers. There were nine guest speakers addressing different types of models used to evaluate different aspects of bioenergy, ranging from technoeconomic models based on the ASPEN software to linear programming models to develop feedstock supply curves for the US. The papers from this workshop have been submitted to Biomass and Bioenergy and are under editorial review.

    Production sharing contracts are one of the most popular forms of contractual system used in petroleum agreements around the world, but the manner in which the fiscal terms and contract parameters impact system measures is complicated and not well understood. The purpose of this paper is to quantify the influence of private and market uncertainty in contractual fiscal systems. A meta-modelling approach is employed that couples the results of a simulation model with regression analysis to construct numerical functionals that quantify the fiscal regime. Relationships are derived that specify how the present value, rate of return, and take statistics vary as a function of the system parameters. The deepwater Girassol field development in Angola is taken as a case study. (author)

    The biology revolution over the last 50 years has been driven by the ascendancy of molecular biology. This was enthusiastically embraced by most biologists because it took us into increasingly familiar territory. It took mysterious processes, such as the replication of genetic material and assigned them parts that could be readily understood by the human mind. When we think of ''molecular machines'' as being the underlying basis of life, we are using a paradigm derived from everyday experience. However, the price that we paid was a relentless drive towards reductionism and the attendant balkanization of biology. Now along comes ''systems biology'' that promises us a solution to the problem of ''knowing more and more about less and less''. Unlike molecular biology, systems biology appears to be taking us into unfamiliar intellectual territory, such as statistics, mathematics and computer modeling. Not surprisingly, systems biology has met with widespread skepticism and resistance. Why do we need systems biology anyway and how does this new area of research promise to change the face of biology in the next couple of decades?

    The objective of this paper is to demonstrate that a bioenergy system has to be considered as an integrated process in which each stage or step interacts with other steps in the overall process. There are a number of stages in the supply and conversion of woody biomass for energy. Each step in the chain has implications for the next step and for overall system efficiency. The resource can take many forms and will have varying physical and chemical characteristics which will influence the efficiency and cost of conversion. The point in the supply chain at which size and moisture content is reduced and the manner in which it is done is influential in determining feedstock delivered cost and overall system costs. To illustrate the interactions within the overall system, the influence of the nature, size and moisture content of delivered feedstocks on costs of generating electricity via thermal conversion processes is examined using a model developed to investigate the inter-relationships between the stages in the supply chain.

    International Nuclear Information System (INIS)

    1992-01-01

    The Nuclear Waste Policy Act (NWPA) of 1982 assigned to the Department of Energy (DOE) the responsibility for managing the disposal of spent nuclear fuel and high-level radioactive waste and established the Office of Civilian Radioactive Waste Management (OCRWM) for that purpose. The Secretary of Energy, in his November 1989 report to Congress (DOE/RW-0247), announced three new initiatives for conduct of the Civilian Radioactive Waste Management (CRWM) program. One of these initiatives was to establish improved management structure and procedures. In response, OCRWM performed a management study and the Direct subsequently issued the Management Systems Improvement Strategy (MSIS) on August 10, 1990, calling for a rigorous implementation of systems engineering principles with a special emphasis on functional analysis. This approach establishes a framework for integrating the program management efforts with the technical requirements analysis into a single, unified, and consistent program. The functional analysis approach recognizes that just the facilities and equipment comprising the physical waste management system must perform certain functions, so must certain programmatic and management functions be performed within the program in order to successfully bring the physical system into being

    Full Text Available Quantum instanton (QI approximation is recently proposed for the evaluations of the chemical reaction rate constants with use of full dimensional potential energy surfaces. Its strategy is to use the instanton mechanism and to approximate time-dependent quantum dynamics to the imaginary time propagation of the quantities of partition function. It thus incorporates the properties of the instanton idea and the quantum effect of partition function and can be applied to chemical reactions of complex systems. In this paper, we present the QI approach and its applications to several complex systems mainly done by us. The concrete systems include, (1 the reaction of H+CH4→H2+CH3, (2 the reaction of H+SiH4→H2+SiH3, (3 H diffusion on Ni(100 surface; and (4 surface-subsurface transport and interior migration for H/Ni. Available experimental and other theoretical data are also presented for the purpose of comparison.

However, the efficacy is not well reported. Therefore, the objective of the study was to conduct a systematic review and meta-analysis of the available evidence on prevention of uncomplicated wound infections by prophylactic topical antibiotics. Materials and methods: The search included Pubmed, Google Scholar, SCOPUS, Embase, Cochrane, ClinicalTrials.gov, International Clinical Trials Registry Platform, National Technical Information Service, and the National Guidelines Clearinghouse. Results: We identified eight randomized controlled trials and four quasi-randomized trials that met the criteria for the systematic review. Of these trials, 11 studies were pooled for meta-analysis to compare the effects of topical antibiotics versus placebo and 4 studies were pooled for comparison of effects of topical antibiotics versus topical antiseptics on uncomplicated wounds. Fewer wound infections occurred in the topical antibiotic arms compared to placebo (pooled risk ratio: 0.57 [95% CI: 0.37 to 0.86]; p=0.01 and pooled risk

    A system for posting hazardous materials into and out of an enclosure, such as a glovebox, through a port in a wall of the enclosure. The port is normally closed by a door which cooperates with a removable end closure, on a container or the like when the latter is presented to and secured at the port. The container is secured in position at the port by means of a rotatable coupling ring. A single interlock ensures that the door cannot be opened in the absence of a container at the port and also that the container cannot be removed from the port when the door is open. In place of the container, a glove secured to a rigid sleeve may be used to enable the operator to perform a work function within the glovebox. (author)

    This book presents an overview of the most recent advances in nonlinear science. It provides a unified view of nonlinear properties in many different systems and highlights many  new developments. While volume 1 concentrates on mathematical theory and computational techniques and challenges, which are essential for the study of nonlinear science, this second volume deals with nonlinear excitations in several fields. These excitations can be localized and transport energy and matter in the form of breathers, solitons, kinks or quodons with very different characteristics, which are discussed in the book. They can also transport electric charge, in which case they are known as polarobreathers or solectrons. Nonlinear excitations can influence function and structure in biology, as for example, protein folding. In crystals and other condensed matter, they can modify transport properties, reaction kinetics and interact with defects. There are also engineering applications in electric lattices, Josephson junction a...

    This paper reports that world styrene demand, paced by a near doubling of combined requirements in East Asia and Oceania, could reach 19.3 million metric tons by 2000, an average growth rate of 3.7%/year. So concludes Chem Systems Inc., Tarrytown, N.Y., in a study of world styrene markets through the end of the century. Pacific Rim styrene production and consumption throughout the 1990s are predicted to make up increasingly larger shares of world markets, while demand and production lag in the U.S. and western Europe. Demand and capacity in other parts of the world will grow in real terms, increasing combined market shares only slightly. Most of the increase will be driven by demand in East Asia and Oceania, where consumption by century's end is expected to increase 4.48 million metric tons from 2.25 million tons in 1991. Meantime, Japan's styrene demand in 2000 is projected at 2.64 million tons, a 500,000 ton increase from 1991 demand but a net market loss of 1.9%

    Full Text Available Transboundary animal movements facilitate the spread of pathogens across large distances. Cross-border cattle trade is of economic and cultural importance in West Africa. This study explores the potential disease risk resulting from large-scale, cross-border cattle trade between Togo, Burkina Faso, Ghana, Benin, and Nigeria for the first time.A questionnaire-based survey of livestock movements of 226 cattle traders was conducted in the 9 biggest cattle markets of northern Togo in February-March 2012. More than half of the traders (53.5% operated in at least one other country. Animal flows were stochastically simulated based on reported movements and the risk of regional disease spread assessed. More than three quarters (79.2%, range: 78.1-80.0% of cattle flowing into the market system originated from other countries. Through the cattle market system of northern Togo, non-neighbouring countries were connected via potential routes for disease spread. Even for diseases with low transmissibility and low prevalence in a given country, there was a high risk of disease introduction into other countries.By stochastically simulating data collected by interviewing cattle traders in northern Togo, this study identifies potential risks for regional disease spread in West Africa through cross-border cattle trade. The findings highlight that surveillance for emerging infectious diseases as well as control activities targeting endemic diseases in West Africa are likely to be ineffective if only conducted at a national level. A regional approach to disease surveillance, prevention and control is essential.

    Full Text Available Background: The treatment of the persistent peritoneo-vaginal duct (PPVD or persistent processus vaginalis (PPV in children by inguinal access carries a real testicular risk that can be avoided using the laparoscopic treatment, mostly in the case of recurrence. We hereby present the results of our first series treated by laparoscopy at Sylvanus Olympio Teaching Hospital. Patients and Methods: This is a descriptive and prospective study on a 6 months period. It concerned 21 boys with mean age of 4 years and 3 months, weighing 15.70 Kg. They clinically presented 12 unilateral inguinal hernias and 9 hydroceles among which one recurrence. We used the Montupet and Esposito technique. The results were considered good in absence of recurrence and bad if recurrence occurred. Results: With 4 over the 21 patients (19.04%, the diagnosis of a controlateral PPV was done per operatory. In those cases, the bilateral closure was systematic in the same operative time. The mean duration of the unilateral treatment was 57.6 minutes (extremes: 45 and 70 min. The mean pneumo-peritoneum pressure was 7.62 mm Hg (extremes: 5 and 8 mm Hg. Seventeen boys (80.95% got out on the same day. There was neither infection nor parietal hematoma. With a mean follow-up of 9.3 months, there was no recurrence. Conclusion: The laparoscopic treatment of the PVDP in children is an efficient procedure. It permits to diagnose and treat at the same time, a controlateral PVDP that had not been found during the clinical examination; it also helps to avoid the traumatisms of the spermatic cord.

    Full Text Available Introduction: The elastic stable intramedullary nailing (ESIN presently seems the best technique in the surgical treatment of femoral shaft fractures (FSF in >6-year-old children. We hereby report technical difficulties and therapeutic results after our first 8 years of experience. Patients and Methods: It′s a retrospective study over a period of 8 years from January 2005 to December 2012 in the Paediatric Surgery Department of Sylvanus Olympio Teaching Hospital of Lomé. Indications, technical particularities and results were studied. Results: There were 32 patients, 17 were boys and 15 were girls, with a mean age of 11 years old. The mean time to surgery was 21 days (range: 14 and 51 days. A callus was always removed before reduction. The osteosynthesis was stable in 22 cases, but in 10 others, it had been completed with a cast immobilisation. The operation needed a blood transfusion in 18 cases. With a mean follow-up of 3.5 years, the results were excellent in 29 patients (90.63% and good in 3 patients (9.37%. Conclusion: Although undertaking an ESIN can be difficult, due to the lack of adequate equipment the procedure produces satisfactory outcome.

    The microgrid has made its mark in distributed generation and has attracted widespread research. However, microgrid is a complex system which needs to be viewed from an intelligent system of systems perspective. In this paper, a network control system of systems is designed for the islanded microgrid system consisting of three distributed generation units as three subsystems supplying a load. The controller stabilises the microgrid system in the presence of communication infractions such as packet dropouts and delays. Simulation results are included to elucidate the effectiveness of the proposed control strategy.

Using the system theory and the theory of systemic risks displayed by the German sociologist Niklas Luhmann the article demonstrates how military systems due to their own autonomy and autopoiesis do not fit into the idea of political government......Decisive parts of the Western political system have demonstrated a seemingly surprising misinterpretation of military might. As Madelaine Albright has suggested, the mighty perceived themselves as "almighty". Political power seems to have invested in instrumental coercive power relations and found....... The Clausewitzian ideal of a political system that could continue its power games by means of war was moderated by Clausewitz' own analysis of "friction".

  6. Systems engineering for very large systems

    Science.gov (United States)

    Lewkowicz, Paul E.

    Very large integrated systems have always posed special problems for engineers. Whether they are power generation systems, computer networks or space vehicles, whenever there are multiple interfaces, complex technologies or just demanding customers, the challenges are unique. 'Systems engineering' has evolved as a discipline in order to meet these challenges by providing a structured, top-down design and development methodology for the engineer. This paper attempts to define the general class of problems requiring the complete systems engineering treatment and to show how systems engineering can be utilized to improve customer satisfaction and profit ability. Specifically, this work will focus on a design methodology for the largest of systems, not necessarily in terms of physical size, but in terms of complexity and interconnectivity.

    2011-01-01

    The implementation of an integrated system health management (ISHM) capability is fundamentally linked to the management of data, information, and knowledge (DIaK) with the purposeful objective of determining the health of a system. It is akin to having a team of experts who are all individually and collectively observing and analyzing a complex system, and communicating effectively with each other in order to arrive at an accurate and reliable assessment of its health. In this paper, concepts, procedures, and approaches are presented as a foundation for implementing an intelligent systems ]relevant ISHM capability. The capability stresses integration of DIaK from all elements of a system. Both ground-based (remote) and on-board ISHM capabilities are compared and contrasted. The information presented is the result of many years of research, development, and maturation of technologies, and of prototype implementations in operational systems.

    Full Text Available Systems approach represents thinking outside the box and is connected to the transformation of common linear approach and thinking. Western society followed rules of classical western science, which form many centuries took analysis as mainstream of thinking and researching. One can find perfect and logical explanation for this. In the past, classical science researched matter and reached optimal results with analysis and analytical thinking. Nowadays more and more scientists research intangible world around matter and cooperate with prevailed, fastest growing service industry such as tourism. Following paper presents systems approach in tourism, which defines wideness, co-dependency among tourism system elements, and "big picture" point of view. In a frame of systems methodology, we will show the importance of systems approach in order to understand complexity in the area of tourism. At once an excellent example of the analytical approach will be shown in so called "the tip of the iceberg" theory, where events represent analytical thinking and structure or base of the iceberg represents systems approach. Complexity of the tourism systems will be explained and a model of a common tourism system developed. We claim that the analysis, in the past, caused technological progress; it caused the development of western science, which we now know it. It led to the discoveries but for dealing with contemporary complex challenges is not sufficient. Today a systems approach is suitable enough for dealing with complex question in the area of tourism and of course in global society.

    The worldwide growth in demand for electricity has forced the pace of developments in electrical power system design to meet consumer needs for reliable, secure and cheap supplies. Power system protection, as a technology essential to high quality supply, is widely recognised as a specialism of growing and often critical importance, in which power system needs and technological progress have combined to result in rapid developments in policy and practice in recent years. In the United Kingdom, the need for appropriate training in power system protection was recognised in the early 1960s with t

    2008-01-01

    One of the major challenges in modern aerospace designs is the integration and assembly of independently developed components. We have formalized this as the system assembly problem: from a sea of available components, which should be selected and how should they be connected, integrated, and assembled so that the overall system requirements are satisfied in a certifiable way? We present a powerful framework for automatically solving the system assembly problem directly from system requirements by using formal verification technology. We also present a case study where we applied our work to large-scale industrial examples from the Boeing Dreamliner.

    The Site Systems Engineering Management Plan (SEMP) is the Westinghouse Hanford Company (WHC) implementation document for the Hanford Site Systems Engineering Policy, (RLPD 430.1) and Systems Engineering Criteria Document and Implementing Directive, (RLID 430.1). These documents define the US Department of Energy (DOE), Richland Operations Office (RL) processes and products to be used at Hanford to implement the systems engineering process at the site level. This SEMP describes the products being provided by the site systems engineering activity in fiscal year (FY) 1996 and the associated schedule. It also includes the procedural approach being taken by the site level systems engineering activity in the development of these products and the intended uses for the products in the integrated planning process in response to the DOE policy and implementing directives. The scope of the systems engineering process is to define a set of activities and products to be used at the site level during FY 1996 or until the successful Project Hanford Management Contractor (PHMC) is onsite as a result of contract award from Request For Proposal DE-RP06-96RL13200. Following installation of the new contractor, a long-term set of systems engineering procedures and products will be defined for management of the Hanford Project. The extent to which each project applies the systems engineering process and the specific tools used are determined by the project`s management.

  15. Hot Spot Removal System: System description

    International Nuclear Information System (INIS)

    1997-09-01

    Hazardous wastes contaminated with radionuclides, chemicals, and explosives exist across the Department of Energy complex and need to be remediated due to environmental concerns. Currently, an opportunity is being developed to dramatically reduce remediation costs and to assist in the acceleration of schedules associated with these wastes by deploying a Hot Spot Removal System. Removing the hot spot from the waste site will remove risk driver(s) and enable another, more cost effective process/option/remedial alternative (i.e., capping) to be applied to the remainder of the site. The Hot Spot Removal System consists of a suite of technologies that will be utilized to locate and remove source terms. Components of the system can also be used in a variety of other cleanup activities. This Hot Spot Removal System Description document presents technologies that were considered for possible inclusion in the Hot Spot Removal System, technologies made available to the Hot Spot Removal System, industrial interest in the Hot Spot Removal System''s subsystems, the schedule required for the Hot Spot Removal System, the evaluation of the relevant technologies, and the recommendations for equipment and technologies as stated in the Plan section

    Full Text Available The main message of this paper is that systemism is best suited for transdisciplinary studies. A description of disciplinary sciences, transdisciplinary sciences and systems sciences is given, along with their different definitions of aims, scope and tools. The rationale for transdisciplinarity is global challenges, which are complex. The rationale for systemism is the concretization of understanding complexity. Drawing upon Ludwig von Bertalanffy’s intention of a General System Theory, three items deserve attention—the world-view of a synergistic systems technology, the world picture of an emergentist systems theory, and the way of thinking of an integrationist systems method.

  20. Systems Theory and Systems Approach to Leadership

    Directory of Open Access Journals (Sweden)

    Dr.Sc. Berim Ramosaj

    2014-06-01

    Full Text Available Systems theory is product of the efforts of many researchers to create an intermediate field of coexistence of all sciences. If not for anything else, because of the magnitude that the use of systemic thinking and systemic approach has taken, it has become undisputed among the theories. Systems theory not only provides a glossary of terms with which researchers from different fields can be understood, but provides a framework for the presentation and interpretation of phenomena and realities. This paper addresses a systematic approach to leadership, as an attempt to dredge leadership and systems theory literature to find the meeting point. Systems approach is not an approach to leadership in terms of a manner of leader’s work, but it’s the leader's determination to factorize in his leadership the external environment and relationships with and among elements. Leader without followers is unable to exercise his leadership and to ensure their conviction he should provide a system, a structure, a purpose, despite the alternative chaos. Systems approach clarifies the thought on the complexity and dynamism of the environment and provides a framework for building ideas. If the general system theory is the skeleton of science (Boulding: 1956, this article aims to replenish it with leadership muscles by prominent authors who have written on systems theory and leadership, as well as through original ideas. In this work analytical methods were used (by analyzing approaches individually as well as synthetic methods (by assaying individual approaches in context of entirety. The work is a critical review of literature as well as a deductive analysis mingled with models proposed by authors through inductive analysis. Meta-analysis has been used to dissect the interaction and interdependence between leadership approaches.

  1. Modeling Power Systems as Complex Adaptive Systems

    2004-12-30

    Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of today's most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This report explores the state-of-the-art physical analogs for understanding the behavior of some econophysical systems and deriving stable and robust control strategies for using them. We review and discuss applications of some analytic methods based on a thermodynamic metaphor, according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood. We apply these methods to the question of how power markets can be expected to behave under a variety of conditions.

    The operation of a 1t/d PSU (process support unit) was studied for the NEDOL coal liquefaction process. For the modification of facilities, product oil reforming facilities were installed. In the coal injection operation, a 59-day slurry operation was carried out using Tanito Harum coal, which was for the evaluation of the reforming effect under the product reforming conditions, operationality, and liquefaction characteristics. A 37-day slurry operation was also performed using Chinese coal, which was intended to pursue improved cost performance and to collect the light oil fraction in the flow of reforming operation. In the operation for maintenance, investigations were conducted into conditions for hydrogenation in a 1-through operation involving the solvent hydrogenation process and the normal pressure distillation facilities and into the effect of pre-hydrogenation solvent properties, which aimed at grasping the effect of product oil reforming measures and their influence on operationality. In the survey of environments, the properties of wastewater from the liquefaction process using Tanito Harum coal were studied and toxicity evaluation tests were conducted for activated sludge.

    As to the development of coal use hydrogen production technology, the paper studied the reactivity of char and ignition characteristics of various coals in the use of electric furnace and the participation in pilot plant test and the improvement, and the FY 1993 results were reported. In the study of reactivity of char, it was found that the reactivity was the same, regardless of the equipment and kind of raw coal, if considered of the ratio of the total oxygen amount (the char-containing oxygen amount added to the oxygen supply amount) to the carbon supply amount in char. In the test on ignition characteristics of overseas coals, the same characteristics as those of the Taiheiyo coal conventionally tested were obtained and it was found that it was good to use the same method for start-up of gasifier as conventionally used. In the pilot plant test in the previous year, slag and ash stuck to the outlet of the gasification part and heat recovery part and developed, which hindered the continued operation. To improve it, the following were carried out: model study, study of ash sintering, study using the synthetic test equipment, analysis of the deposit in gasifier, etc. Based on these results, the plant was improved, and the continued operation of 1,149 hours was stably achieved in RUN8.

    The System Performance Optimization has become an important and difficult field for large scientific computer centres. Important because the centres must satisfy increasing user demands at the lowest possible cost. Difficult because the System Performance Optimization requires a deep understanding of hardware, software and workload. The optimization is a dynamic process depending on the changes in hardware configuration, current level of the operating system and user generated workload. With the increasing complication of the computer system and software, the field for the optimization manoeuvres broadens. The hardware of two manufacturers IBM and CDC is discussed. Four IBM and two CDC operating systems are described. The description concentrates on the organization of the operating systems, the job scheduling and I/O handling. The performance definitions, workload specification and tools for the system stimulation are given. The measurement tools for the System Performance Optimization are described. The results of the measurement and various methods used for the operating system tuning are discussed. (Auth.)

    The Rover Waste Assay System (RWAS) is a nondestructive assay system designed for the rapid assay of highly-enriched 235 U contaminated piping, tank sections, and debris from the Rover nuclear rocket fuel processing facility at the Idaho Chemical Processing Plant. A scanning system translates a NaI(Tl) detector/collimator system over the structural components where both relative and calibrated measurements for 137 Cs are made. Uranium-235 concentrations are in operation and is sufficiently automated that most functions are performed by the computer system. These functions include system calibration, problem identification, collimator control, data analysis, and reporting. Calibration of the system was done through a combination of measurements on calibration standards and benchmarked modeling. A description of the system is presented along with the methods and uncertainties associated with the calibration and analysis of the system for components from the Rover facility. 4 refs., 2 figs., 4 tabs

    The ITER reference system uses low-temperature water for heat removal and high-temperature helium for bake-out. As these systems share common equipment, bake-out cannot be performed until the cooling system is drained and dried, and the reactor cannot be started until the helium has been purged from the cooling system. This study examines the feasibility of using a single high-temperature fluid to perform both heat removal and bake-out. The high temperature required for bake-out would also be in the range for power production. The study examines cost, operational benefits, and impact on reactor safety of two options: a high-pressure water system, and a low-pressure organic system. It was concluded that the cost savings and operational benefits are significant; there are no significant adverse safety impacts from operating either the water system or the organic system; and the capital costs of both systems are comparable

    1993-11-01

    In this article, we looked at some decisions that apply to the design of reliable computer systems. We began with a discussion of several terms such as testability, then described some systems that call for highly reliable hardware and software. The article concluded with a discussion of methods that can be used to achieve higher reliability in computer systems. Reliability and fault tolerance in computers probably will continue to grow in importance. As more and more systems are computerized, people will want assurances about the reliability of these systems, and their ability to work properly even when sub-systems fail.

  7. User Registration Systems for Distributed Systems

    Murphy, K. J.; Cechini, M.; Pilone, D.; Mitchell, A.

    2010-12-01

    As NASA’s Earth Observing System Data and Information System (EOSDIS) systems have evolved over the years, most of the EOSDIS data are now available to users via anonymous on-line access. Although the changes have improved the dissemination efficiency of earth science data, the anonymous access has made it difficult to characterize users, capture metrics on the value of EOSDIS and provide customized services that benefit users. As the number of web-based applications continues to grow, data centers and application providers have implemented their own user registration systems and provided new tools and interfaces for their registered users. This has led to the creation of independent registration systems for accessing data and interacting with online tools and services. The user profile information maintained at each of these registration systems is not consistent and the registration enforcement varies by system as well. This problem is in no way unique to EOSDIS and represents a general challenge to the distributed computing community. In a study done in 2007(http://www2007.org/papers/paper620.pd), the average user has approximately 7 passwords for about 25 accounts and enters a password 8 times a day. These numbers have only increased in the last three years. To try and address this, a number of solutions have been offered including Single Sign-On solutions using a common backend like Microsoft Active Directory or an LDAP server, trust based identity providers like OpenID, and various forms of authorization delegation like OAuth or SAML/XACML. This talk discusses the differences between authentication and authorization, the state of the more popular user registration solutions available for distributed use, and some of the technical and policy drivers that need to be considered when incorporating a user registration system into your application.

  8. SUBSURFACE EMPLACEMENT TRANSPORTATION SYSTEM

    Wilson, T.; Novotny, R.

    1999-01-01

    The objective of this analysis is to identify issues and criteria that apply to the design of the Subsurface Emplacement Transportation System (SET). The SET consists of the track used by the waste package handling equipment, the conductors and related equipment used to supply electrical power to that equipment, and the instrumentation and controls used to monitor and operate those track and power supply systems. Major considerations of this analysis include: (1) Operational life of the SET; (2) Geometric constraints on the track layout; (3) Operating loads on the track; (4) Environmentally induced loads on the track; (5) Power supply (electrification) requirements; and (6) Instrumentation and control requirements. This analysis will provide the basis for development of the system description document (SDD) for the SET. This analysis also defines the interfaces that need to be considered in the design of the SET. These interfaces include, but are not limited to, the following: (1) Waste handling building; (2) Monitored Geologic Repository (MGR) surface site layout; (3) Waste Emplacement System (WES); (4) Waste Retrieval System (WRS); (5) Ground Control System (GCS); (6) Ex-Container System (XCS); (7) Subsurface Electrical Distribution System (SED); (8) MGR Operations Monitoring and Control System (OMC); (9) Subsurface Facility System (SFS); (10) Subsurface Fire Protection System (SFR); (11) Performance Confirmation Emplacement Drift Monitoring System (PCM); and (12) Backfill Emplacement System (BES)

    1998-01-01

    A system and method provides for the creation of a highly graphical expert system without the need for programming in code. An expert system is created by initially building a data interface, defining appropriate Mission, User-Defined, Inferred, and externally-generated GenSAA (EGG) data variables whose data values will be updated and input into the expert system. Next, rules of the expert system are created by building appropriate conditions of the rules which must be satisfied and then by building appropriate actions of rules which are to be executed upon corresponding conditions being satisfied. Finally, an appropriate user interface is built which can be highly graphical in nature and which can include appropriate message display and/or modification of display characteristics of a graphical display object, to visually alert a user of the expert system of varying data values, upon conditions of a created rule being satisfied. The data interface building, rule building, and user interface building are done in an efficient manner and can be created without the need for programming in code.

  10. Operating System for Runtime Reconfigurable Multiprocessor Systems

    Directory of Open Access Journals (Sweden)

    Diana Göhringer

    2011-01-01

    Full Text Available Operating systems traditionally handle the task scheduling of one or more application instances on processor-like hardware architectures. RAMPSoC, a novel runtime adaptive multiprocessor System-on-Chip, exploits the dynamic reconfiguration on FPGAs to generate, start and terminate hardware and software tasks. The hardware tasks have to be transferred to the reconfigurable hardware via a configuration access port. The software tasks can be loaded into the local memory of the respective IP core either via the configuration access port or via the on-chip communication infrastructure (e.g. a Network-on-Chip. Recent-series of Xilinx FPGAs, such as Virtex-5, provide two Internal Configuration Access Ports, which cannot be accessed simultaneously. To prevent conflicts, the access to these ports as well as the hardware resource management needs to be controlled, e.g. by a special-purpose operating system running on an embedded processor. For that purpose and to handle the relations between temporally and spatially scheduled operations, the novel approach of an operating system is of high importance. This special purpose operating system, called CAP-OS (Configuration Access Port-Operating System, which will be presented in this paper, supports the clients using the configuration port with the services of priority-based access scheduling, hardware task mapping and resource management.

  11. Business system: Sustainable development and anticipatory system

    Directory of Open Access Journals (Sweden)

    Vojko Potočan

    2002-01-01

    Full Text Available The existence and development of humankind depends mainly upon the co-ordinated operation of all areas and levels of human activity. However, in theory and in practice there is no model of operation, which would provide a harmonized and target oriented development. A partial solution is offered by sustainable development, which tries to define and carry out common goals of mankind with a harmonized implementation of human activities at all levels of its living and behaviour. Companies belong to central institutions of modern society which essentially co–create the sustainability of society. The company’s endeavour by simulation to prepare models of their goals concerning their internal and external environment. On the base of systemic treatment, we can define companies as business system, which can survive in a log-run only on the basis of sustainable development. The business system can also be supported by the application of the anticipatory systems. The anticipatory systems can be, in this sense, understood as an entity of the methodological approach, techniques and modes of work. Their characteristics have, a direct impact on the determination of goals, on the orientation of operation, and hence on the achievement of the business system results.

    CERN Document Server

    Benzaouia, Abdellah

    2012-01-01

    Saturated Switching Systems treats the problem of actuator saturation, inherent in all dynamical systems by using two approaches: positive invariance in which the controller is designed to work within a region of non-saturating linear behaviour; and saturation technique which allows saturation but guarantees asymptotic stability. The results obtained are extended from the linear systems in which they were first developed to switching systems with uncertainties, 2D switching systems, switching systems with Markovian jumping and switching systems of the Takagi-Sugeno type. The text represents a thoroughly referenced distillation of results obtained in this field during the last decade. The selected tool for analysis and design of stabilizing controllers is based on multiple Lyapunov functions and linear matrix inequalities. All the results are illustrated with numerical examples and figures many of them being modelled using MATLAB®. Saturated Switching Systems will be of interest to academic researchers in con...
