    1979-01-01

    Since April 1960, following the closing of the Shinkolobwe mine, the Republic of Zaire has ceased to be a producer of uranium. Nevertheless, Gecamines (Generale des carrieres et mines du Zaire), a wholly state-owned company, is continuing its research on uranium occurrences which have been discovered in its concession in the course of aerial radiometric prospecting. The most recent campaign was the one carried out in 1969 and 1972 by Hunting Company. On-the-ground verification of these shows has not yet resulted in the discovery of a workable deposit. There are other sectors cutting across Zaire which might well contain uranium deposits: this is true of the sedimentary phosphates of the region of Lower Zaire as well as of the frontier region between Zaire and the Central African Empire. However, no detailed exploration work has yet been carried out. (author)

  3. Wave-like spread of Ebola Zaire.

    Directory of Open Access Journals (Sweden)

    2005-11-01

    Full Text Available In the past decade the Zaire strain of Ebola virus (ZEBOV has emerged repeatedly into human populations in central Africa and caused massive die-offs of gorillas and chimpanzees. We tested the view that emergence events are independent and caused by ZEBOV variants that have been long resident at each locality. Phylogenetic analyses place the earliest known outbreak at Yambuku, Democratic Republic of Congo, very near to the root of the ZEBOV tree, suggesting that viruses causing all other known outbreaks evolved from a Yambuku-like virus after 1976. The tendency for earlier outbreaks to be directly ancestral to later outbreaks suggests that outbreaks are epidemiologically linked and may have occurred at the front of an advancing wave. While the ladder-like phylogenetic structure could also bear the signature of positive selection, our statistical power is too weak to reach a conclusion in this regard. Distances among outbreaks indicate a spread rate of about 50 km per year that remains consistent across spatial scales. Viral evolution is clocklike, and sequences show a high level of small-scale spatial structure. Genetic similarity decays with distance at roughly the same rate at all spatial scales. Our analyses suggest that ZEBOV has recently spread across the region rather than being long persistent at each outbreak locality. Controlling the impact of Ebola on wild apes and human populations may be more feasible than previously recognized.

    This paper gives informations on petroleum and natural gas industry, petroleum market and prices, trade and contracts, prospection and production. The possible return of Iraq on the petroleum market has an influence on petroleum prices. In Algeria, Sonatrach will deliver 2.5 milliards m 3 to Portugal through the Maghreb-Europe gas pipeline. In Tunisia, a petroleum exploration permit has been attributed to Atlantic Richfield Company and Miskar natural gas field would come into production in 1995. In Saudi Arabia, Saudi Aramco has bought all the petroleum refining and distribution interests of the Saudi Arabian Marketing and Refining Company and Petromin Company and now Saudi Aramco is become a national integrated petroleum company. Petroleum exploration is going on in Caspian sea (Iran), six new oil fields have come into production in the Deir ez-Zor and Ash Sham permits (Syria) and petroleum exploration contracts have been signed in Angola, Nigeria and Zaire. In Egypt, the growth of natural gas consumption gives an indication upon the future growing deficit

    Full Text Available This study presents the evolution of agricultural production of Zaire before and after 1960 with the help of variable quantifies of products, the cultured area and the exported quantifies of products. A comparative analysis of quantifies of studied products shows that after 1960, the agricultural production of basis foodstuffs of the Zairian population has fallen of the order of 91 % in comparison with the first period. This study shows that the system of peasantry introduced in 1936 by the INEAC, the rationalization of cultural methods connected to the governmental explain the agricultural expansion of Zaire before 1960.

  8. Electricity demand in Tunisia

    International Nuclear Information System (INIS)

    Gam, Imen; Ben Rejeb, Jaleleddine

    2012-01-01

    This paper examines the global electricity demand in Tunisia as a function of gross domestic product in constant price, the degree of urbanization, the average annual temperature, and the real electricity price per Kwh. This demand will be examined employing annual data over a period spanning almost thirty one years from 1976 to 2006. A long run relationship between the variables under consideration is determined using the Vector Autoregressive Regression. The empirical results suggest that the electricity demand in Tunisia is sensitive to its past value, any changes in gross domestic product and electricity price. The electricity price effects have a negative impact on long-run electricity consumption. However, the gross domestic product and the past value of electricity consumption have a positive effect. Moreover, the causality test reveals a unidirectional relationship between price and electricity consumption. Our empirical findings are effective to policy makers to maintain the electricity consumption in Tunisia by using the appropriate strategy. - Highlights: ► This paper examined the electricity demand in Tunisia in the long-run. ► The empirical analysis revealed that in the long-run the electricity demand is affected by changes in its past value, GDP in constant price and real electricity price. ► There is a unidirectional relationship between price and electricity consumption, that is to say, that the electricity price causes the consumption. ► Those results suggest that a pricing policy can be an effective instrument to rationalize the electricity consumption in Tunisia in the long-run.

    The development status of acupuncture and moxibustion in Tunisia is introduced in this article. Although acupuncture and moxibustion only has a history of more than 30 years in Tunisia, it is very popular among the local people. Until now, there is one acupuncture and moxibustion center aided and built with the help of the Chinese government. Acupuncture and moxibustion clinical department has been set in some of the hospitals, and acupuncture and moxibustion clinical practice is also carried out in some private clinics. Cost of acupuncture and moxibustion in public hospitals has already been covered by medical insurance. As for education of acupuncture and moxibustion, training courses were set up in medical colleges of Tunisia by Tunisian government which is lectured by Chinese acupuncture experts. Acupuncture and moxibustion has been used to treat many diseases in Tunisia and is warmly welcomed by Tunisian.

    The north African country of Tunisia (632,387 square miles) consists largely of desert, with some rich farmlands and a rocky transitional zone. Despite the government's family planning efforts, the population grew from 5.6 million in 1975, to 7.2 million in 1985, and, with its 2.4% annual growth rate, is projected to reach 8.1 million by 1990. Tunisia's rural population decreased to 46% in 1985 as workers and their families moved into urban areas. 98% of the population is Arab-Berber; Arabic and French are the offical languages. The age-sex distribution is typical of developing countries; the median age has increased from 16.8 years in 1966 to 19.5 in 1950 and persons over age 60 have increased from 5.1% in 1956 to 6.7% in 1980. Tunisian families average 5.7 persons in rural areas, and 5.4 persons in urban one. Marriages are declining, polygamy is outlawed, and divorce, once easy, is more difficult and declining. At independence in 1956, only 15% of Tunisians were literate, now 85-90% of primary school age children are enrolled and literacy had risen to 53% in 1980. Women, once heavily veiled, now have full rights and access to education. More than 60 thousand new workers compete for the 40,000 new job openings each year. An estimated 7000 laborers found work in Europe in 1984. Women composed only 11% of the 1975 work force, but by 1980, held 20% of jobs, although they were mainly low paying positions. In 1980, 35% of the laborers worked in agriculture, 19% in industry, 17% in service industries, and 10% in construction. Agriculture and tourism have declined in recent years, contributing to social unrest, currency decline, and inflated wages and consumer prices.

    2008-01-01

    In order to determine level of natural radioactivity and to eventually identify areas where radon concentrations are elevated, measurements of indoor air radon concentrations were carried out in Tunisian houses since 1999. Passive alpha-track open Kodalpha dosimeters have been placed in one or two rooms by dwellings at 1 m to 1.50 m from soil. The first campaign controlled the capital, Tunis, and lasted 14 months by two months periods. The annual median was 30 Bq m -3 . In the 120 surveyed houses, a seasonal variation has been found with the highest concentrations unregistered in winter. The second campaign was conducted in 1,151 houses situated in all the inhabited areas of Tunisia during two winter months. The median was 36 Bq m -3 with a maximum of 512 Bq m -3 . The majority of results were lower than 100 Bq m -3 . Only 5.5% of results were comprised between 100 and 200 Bq m -3 and 0.7% between 200 and 400 Bq m -3 . The third campaign was performed in an area where inhabitants used to live in underground homes. Sixty modern and sixty underground houses were controlled during one year by three months periods. The results were significantly different with a median at 46.5 Bq m -3 in the modern houses and 305 Bq m -3 in the underground caves with a maximum at 1,563 Bq m -3 . 54% of results were under 100 Bq m -3 , 32% between 100 and 400, 13% between 400 and 1,000 Bq m -3 . Only 1% (two underground houses) were higher than 1,000 Bq m -3 . A careful enquiry showed that most of these underground houses are no more inhabited and are rarely opened. In these dwellings, the highest concentrations were found during summer. Most of the indoor radon concentration levels found in Tunisia were under international recommended levels. (author)

    (See the editorial commentary by Bausch, on pages 179-81.) Reston ebolavirus was recently detected in pigs in the Philippines. Specific antibodies were found in pig farmers, indicating exposure to the virus. This important observation raises the possibility that pigs may be susceptible to Ebola virus infection, including from other species, such as Zaire ebolavirus (ZEBOV), and can transmit to other susceptible hosts. This study investigated whether ZEBOV, a species commonly reemerging in central Africa, can replicate and induce disease in pigs and can be transmitted to naive animals. Domesticated Landrace pigs were challenged through mucosal exposure with a total of 1 ×10(6) plaque-forming units of ZEBOV and monitored for virus replication, shedding, and pathogenesis. Using similar conditions, virus transmission from infected to naive animals was evaluated in a second set of pigs. Following mucosal exposure, pigs replicated ZEBOV to high titers (reaching 10(7) median tissue culture infective doses/mL), mainly in the respiratory tract, and developed severe lung pathology. Shedding from the oronasal mucosa was detected for up to 14 days after infection, and transmission was confirmed in all naive pigs cohabiting with inoculated animals. These results shed light on the susceptibility of pigs to ZEBOV infection and identify an unexpected site of virus amplification and shedding linked to transmission of infectious virus.

  15. Proterozoic strata-bound uranium deposits of Zambia and Zaire

    1984-01-01

    The Katanga System, host to uranium and copper mineralisation, is several thousands of metres thick and rests unconformably on an older complex of crystalline rocks and metasediments and is locally covered by Karoo sandstones or Kalahari sands. The deposition of the Katanga System took place during the Late Proterozoic in a wide complex basin extending from Shaba province in Zaire through a large part of Zambia and into eastern Angola. The sediments were affected by different grades of metamorphism, tectonic events, and by thermal events associated with post-tectonic metamorphism. At the base of Katanga system there are 84 known copper deposits and 42 uranium occurrences. It is suggested that all the known uranium and copper occurrences are of an essentially syngenetic sedimentary origin. The mineralisation is found in the Lower Roan Formation near the base of the Katanga System occurring in rocks produced in similar environmental conditions and thus being stratigraphic controlled, however, their areal distribution is localised producing a regional metal zonation. Many of the uranium occurrences have a typical vein aspect. These transgressive relationships are not inconsistent with a syngenetic origin as evidenced by the vein morphology. (author)

  16. Similarity is not enough: Tipping points of Ebola Zaire mortalities

    Science.gov (United States)

    Phillips, J. C.

    2015-06-01

    In early 2014 an outbreak of a slightly mutated Zaire Ebola subtype appeared in West Africa which is less virulent than 1976 and 1994 strains. The numbers of cases per year appear to be ∼1000 times larger than the earlier strains, suggesting a greatly enhanced transmissibility. Although the fraction of the 2014 spike glycoprotein mutations is very small (∼3%), the mortality is significantly reduced, while the transmission appears to have increased strongly. Bioinformatic scaling had previously shown similar inversely correlated trends in virulence and transmission in N1 (H1N1) and N2 (H3N2) influenza spike glycoprotein mutations. These trends appear to be related to various external factors (migration, availability of pure water, and vaccination programs). The molecular mechanisms for Ebola's mutational response involve mainly changes in the disordered mucin-like domain (MLD) of its spike glycoprotein amino acids. The MLD has been observed to form the tip of an oligomeric amphiphilic wedge that selectively pries apart cell-cell interfaces via an oxidative mechanism.

    The rising level of energy consumption that is occurring internationally also is being mirrored at regional and national levels. An interesting case study along these lines is Tunisia, which is one of the high-growth economies in the Middle East and North African area yet lacks sufficient energy supply to satisfy its growing demand. Tunisia looks like many nations around the world with a young population, growing economy, increasing domestic energy consumption, and the need to balance economic development with environmental concerns.

    Eight guinea pigs were aerosolized with guinea pig-adapted Zaire ebolavirus (variant: Mayinga) and developed lethal interstitial pneumonia that was distinct from lesions described in guinea pigs challenged subcutaneously, nonhuman primates challenged by the aerosol route, and natural infection in humans. Guinea pigs succumbed with significant pathologic changes primarily restricted to the lungs. Intracytoplasmic inclusion bodies were observed in many alveolar macrophages. Perivasculitis was noted within the lungs. These changes are unlike those of documented subcutaneously challenged guinea pigs and aerosolized filoviral infections in nonhuman primates and human cases. Similar to findings in subcutaneously challenged guinea pigs, there were only mild lesions in the liver and spleen. To our knowledge, this is the first report of aerosol challenge of guinea pigs with guinea pig-adapted Zaire ebolavirus (variant: Mayinga). Before choosing this model for use in aerosolized ebolavirus studies, scientists and pathologists should be aware that aerosolized guinea pig-adapted Zaire ebolavirus (variant: Mayinga) causes lethal pneumonia in guinea pigs. © The Author(s) 2014.

  8. Tunisia: high fertility stalls development.

    Science.gov (United States)

    Barberis, M

    1985-01-01

    Despite government policy enacted in 1964 to reduce fertility in order to hasten socioeconomic progress, population pressures continue to impair development in Tunisia. The birth rate fell 20% over the last 2 decades, but this accomplishment has been outweighed by a 50% decline in mortality rates. As a result, the rate of natural population increase has remained relatively constant at 2.5%/year. The initial decline in fertility that followed introduction of the national family planning program appears to have reached a plateau, explained in part by the resurgence of conservatism and religious fundamentalism and the consequent emphasis on women's childbearing roles. Unemployment in rural areas has led to widespread migration and unemployment is as high as 20% in the nonagricultural sector. Many young Tunisians lack adequate educational preparation to enter the labor force; in 1982, 27% of new job entrants could not read or write. The government's plan to decentralize development to stabilize population and achieve equilibrium between regions has been thwarted by the pace of population growth and limited resources. The rural regions where population is increasing the fastest are also the most difficult to reach with family planning programs. On the other hand, there have been some successes in this area when services have been adapted to the lifestyle and traditions of those in these isolated rural villages.

  11. Ebola Zaire virus blocks type I interferon production by exploiting the host SUMO modification machinery.

    Directory of Open Access Journals (Sweden)

    Tsung-Hsien Chang

    2009-06-01

    Full Text Available Ebola Zaire virus is highly pathogenic for humans, with case fatality rates approaching 90% in large outbreaks in Africa. The virus replicates in macrophages and dendritic cells (DCs, suppressing production of type I interferons (IFNs while inducing the release of large quantities of proinflammatory cytokines. Although the viral VP35 protein has been shown to inhibit IFN responses, the mechanism by which it blocks IFN production has not been fully elucidated. We expressed VP35 from a mouse-adapted variant of Ebola Zaire virus in murine DCs by retroviral gene transfer, and tested for IFN transcription upon Newcastle Disease virus (NDV infection and toll-like receptor signaling. We found that VP35 inhibited IFN transcription in DCs following these stimuli by disabling the activity of IRF7, a transcription factor required for IFN transcription. By yeast two-hybrid screens and coimmunoprecipitation assays, we found that VP35 interacted with IRF7, Ubc9 and PIAS1. The latter two are the host SUMO E2 enzyme and E3 ligase, respectively. VP35, while not itself a SUMO ligase, increased PIAS1-mediated SUMOylation of IRF7, and repressed Ifn transcription. In contrast, VP35 did not interfere with the activation of NF-kappaB, which is required for induction of many proinflammatory cytokines. Our findings indicate that Ebola Zaire virus exploits the cellular SUMOylation machinery for its advantage and help to explain how the virus overcomes host innate defenses, causing rapidly overwhelming infection to produce a syndrome resembling fulminant septic shock.

    For Tunisia, the oil crisis and the decrease in local energy resources gave impetus to geothermal energy for potential assessment, exploration and utilization. Research undertaken showed a country with real potentialities either by its important deep aquifers or by the relatively high values of geothermal gradient and heat flow. This paper reports that it is expected that these efforts of geothermal investigation will continue in the future

    A study of seroprevalence of the human immunodeficiency virus involving 2384 (96%) of Mama Yemo Hospital's (Kinshasa, Zaire) 2492 personnel found 152 (6.4%) to be seropositive. Prevalence was higher among women than among men (8.1% vs 5.2%); in women peak seroprevalence (13.9%) occurred in 20 to 29-year-olds. Workers most likely to be seropositive were those who were relatively young, those who were unmarried, those reporting a blood transfusion or hospitalization during the previous ten years, and those receiving medical injections during the previous three years. Medical, administrative, and manual workers had similar seroprevalence (6.5%, 6.4%, and 6.0%, respectively), and seropositivity was not associated with any measure of patient, blood, or needle contact. These findings are consistent with other hospital-based studies indicating low risks for occupational transmission of human immunodeficiency virus

    This article announces the expansion of Zaire's social marketing program for condoms to high-risk groups in the cities of Goma and Matadi. The program will use proven marketing techniques from Kinshasha, printed materials, and direct marketing to retail outlets, emphasizing hotels, bars, and other areas frequented by prostitutes, migrants, and other travelers. In addition to retail outlets such as pharmacies, 50 taxis will be tested as additional retail sources for Prudence condoms. Once under way, this effort could reach as many as 96,000 people/day. 5 new AIDS information spots are being televised, and an anti-AIDS song and jingle are on the air. Condom social marketing representatives report a 357% increase in condom sales through March, 1989, over 1988, and that products are now available in 85% of Kinshasha pharmacies. Medical center coverage has increased to 14 from 9 zones, while products reach 11 additional cities and 5 interior provinces.

    1994-01-01

    In July 1994, one of the worst cholera epidemics broke out among the nearly a million Rwandan refugees in Goma, eastern Zaire. The United Nations High Commission for Refugees estimated that nearly 12,000 people died during the epidemic. The International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) sent an eight-member medical team to Goma headed by Dr AK Siddique, a senior scientist of the Center and head of the Epidemic Control Preparedness Program, Dacca, Bangladesh. During their two-week stay, the team, in collaboration with UNICEF and the Ministry of Health, Zaire, conducted epidemiological assessment, operated a temporary treatment center and provided technical advice on case management of cholera and shigellosis to other health workers. The team also set up a microbiology laboratory in Goma to identify the pathogens responsible for the epidemic and their drug sensitivity patterns. The team visited a number of temporary treatment facilities in two of the five camp sites and provided technical advice to the health-care providers. They also visited treatment facilities in Goma city, where an estimated 200,000 refugees were affected by the epidemic. Deaths from cholera even in the treatment centers were much higher than expected. The overall case-fatality rate in the treatment centers was nearly 15%. Laboratory investigations showed that the initial epidemic was indeed caused by Vibrio cholerae strains resistant to tetracycline and doxycycline. By the first week of August, the number of cholera cases was declining, but the number of dysentery cases was increasing rapidly. Predominantly Shigella dysenteriae type 1 was responsible, which was resistant to most drugs used for treating shigellosis, except mecillinam. Inappropriate rehydration therapy and inadequate experience of health workers failed to prevent deaths. The team took over the operation of temporary treatment center at Katindo in Goma city with one of the highest case-fatality rates (14

    The authors describe the extension of an outbreak of bacillary dysentery among the Rwandese populations seeking refuge in the region of Goma, Zaire in august 1994. Analysis of the epidemiological surveillance data and of the bacteriological laboratory results of the Bioforce, show that this epidemic was probably facilitated by the preceding cholera outbreak. In such circumstances, rapid sterilization of the virus reservoir, by short course treatments, might be beneficial in limiting the extension of the epidemic.

    The enterovirus (EV) types echovirus (E-) 5, E-9, and E-18, and coxsackievirus (CV-) A9 are infrequently reported in human diseases and their epidemiologic features are poorly defined. Virus transmission patterns between countries have been estimated with phylogenetic data derived from the 1D/VP1 and 3CD gene sequences of a sample of 74 strains obtained in France (2000-2012) and Tunisia (2011-2013) and from the publicly available sequences. The EV types (E-5, E-9, and E-18) exhibited a lower worldwide genetic diversity (respective number of genogroups: 4, 5, and 3) in comparison to CV-A9 (n = 10). The phylogenetic trees estimated with both 1D/VP1 and 3CD sequence data showed variations in the number of co-circulating lineages over the last 20 years among the four EV types. Despite the low number of genogroups in E-18, the virus exhibited the highest number of recombinant 3CD lineages (n = 10) versus 4 (E-5) to 8 (E-9). The phylogenies provided evidence of multiple transportation events between France and Tunisia involving E-5, E-9, E-18, and CV-A9 strains. Virus spread events between France and 17 other countries in five continents had high probabilities of occurrence as those between Tunisia and two European countries other than France. All transportation events were supported by BF values > 10. Inferring the source of virus transmission from phylogenetic data may provide insights into the patterns of sporadic and epidemic diseases caused by EVs.

    Full Text Available Paraphenylenediamine (PPD represents the main active substance in the color of hair dyes. In Tunisia, PPD poisoning is very common, especially in rural areas where the consequences linked to this toxic substance are still unknown. In this paper, we report a case of PPD poisoning and confirm the diagnosis by a qualitative method of analysis. We discuss the clinical manifestations and study the kinetics of biological parameters during the monitoring of the poisoning. The main complication was renal failure and the treatment was basically symptomatic.

  4. Particulate and dissolved organic carbon and chlorophyll A in the Zaire river, estuary and plume

    Science.gov (United States)

    Cadée, G. C.

    Data were collected on POC, DOC and phytoplankton in the Zaire river, estuary and plume. Mean river value for POC was 1.1 mg·l -1, 4.7% of the suspended matter. Average DOC content of the river water was 8.5 mg·l -1. These values are in accordance with the calculations of TOC input from rivers to the world's ocean. Within the estuary POC and chlorophyll decreased regularly up to a salinity of 20. Between salinities of 20 and 32 small phytoplankton bloom occurred resulting also in higher POC values. DOC mixed conservatively up to a salinity of 25; at salinities above 25, values indicate DOC production. This DOC production occurred partly in the bottom water of the canyon where low oxygen values indicated mineralization and conversion of the accumulated POC into DOC. Another area of DOC production observed inside and outside the surface waters of the plume, was partly related to autolysis and degradation of the phytoplankton bloom. This study shows that the influence of rivers on the organic carbon in the ocean will not be confined to the amount introduced directly, but that we have to add the amounts of POC and DOC resulting from enhanced phytoplankton primary production by nutrient input from rivers and by river induced upwelling.

    The cyanobacterial lectin scytovirin (SVN) binds with high affinity to mannose-rich oligosaccharides on the envelope glycoprotein (GP) of a number of viruses, blocking entry into target cells. In this study, we assessed the ability of SVN to bind to the envelope GP of Zaire Ebola virus (ZEBOV) and inhibit its replication. SVN interacted specifically with the protein's mucin-rich domain. In cell culture, it inhibited ZEBOV replication with a 50% virus-inhibitory concentration (EC50) of 50 nM, and was also active against the Angola strain of the related Marburg virus (MARV), with a similar EC50. Injected subcutaneously in mice, SVN reached a peak plasma level of 100 nm in 45 min, but was cleared within 4h. When ZEBOV-infected mice were given 30 mg/kg/day of SVN by subcutaneous injection every 6h, beginning the day before virus challenge, 9 of 10 animals survived the infection, while all infected, untreated mice died. When treatment was begun one hour or one day after challenge, 70-90% of mice survived. Quantitation of infectious virus and viral RNA in samples of serum, liver and spleen collected on days 2 and 5 postinfection showed a trend toward lower titers in treated than control mice, with a significant decrease in liver titers on day 2. Our findings provide further evidence of the potential of natural lectins as therapeutic agents for viral infections. Published by Elsevier B.V.

    Rodent models that accurately reflect human filovirus infection are needed as early screens for medical countermeasures. Prior work in rodents with the Zaire species of Ebola virus (ZEBOV) primarily used inbred mice and guinea pigs to model disease. However, these inbred species do not show some of the important features of primate ZEBOV infection, most notably, coagulation abnormalities. Thirty-six outbred guinea pigs were infected with guinea pig-adapted ZEBOV and examined sequentially over an 8-day period to investigate the pathologic events that lead to death. Features of disease in ZEBOV-infected outbred guinea pigs were largely consistent with disease in humans and nonhuman primates and included early infection of macrophages and dendritiform cells, apoptosis of bystander lymphocytes, and increases in levels of proinflammatory cytokines. Most importantly, dysregulation of circulating levels of fibrinogen, protein C activity, and antifibrinolytic proteins and deposition of fibrin in tissues demonstrated both biochemical and microscopic evidence of disseminated intravascular coagulation. These findings suggest that the outbred guinea pig model recapitulates ZEBOV infection of primates better than inbred rodent models, is useful for dissecting key events in the pathogenesis of ZEBOV, and is useful for evaluating candidate interventions prior to assessment in primates. © The Author 2015.

    The plant cell is able to produce the VP40 antigen from the Zaire ebolavirus , retaining the antigenicity and the ability to induce immune responses in BALB/c mice. The recent Ebola outbreak evidenced the need for having vaccines approved for human use. Herein we report the expression of the VP40 antigen from the Ebola virus as an initial effort in the development of a plant-made vaccine that could offer the advantages of being cheap and scalable, which is proposed to overcome the rapid need for having vaccines to deal with future outbreaks. Tobacco plants were transformed by stable DNA integration into the nuclear genome using the CaMV35S promoter and a signal peptide to access the endoplasmic reticulum, reaching accumulation levels up to 2.6 µg g -1 FW leaf tissues. The antigenicity of the plant-made VP40 antigen was evidenced by Western blot and an initial immunogenicity assessment in test animals that revealed the induction of immune responses in BALB/c mice following three weekly oral or subcutaneous immunizations at very low doses (125 and 25 ng, respectively) without accessory adjuvants. Therefore, this plant-based vaccination prototype is proposed as an attractive platform for the production of vaccines in the fight against Ebola virus disease outbreaks.

    1996-01-01

    A Primary Health Care (PHC) system may be effective and efficient to the extent that essential drugs are available in health services and financially accessible to the population. In developing countries, besides the difficulties related to supplying health services with adequate amounts of drugs, the control of drug consumption is one of the frequent problems encountered by health authorities. Literature is relatively abundant in the field of rationalization of the diagnosis and drug prescription processes, and also in the field of drug financing mechanisms; publications are however rather scarce when topics related to corruption or drug misappropriation are concerned. The case study submitted hereafter reports a drug overconsumption problem in the health centres (HC) of the Kasongo district (Zaire). Despite the existence of direct control mechanisms as well as indirect ones (monitoring of drug consumption by HC), the problem has been identified belatedly. The district staff then used a step-by-step analysis of the HC drug consumption profiles; this analysis allowed to demonstrate that misappropriation would be the most plausible hypothesis. In order to solve the misappropriation problem-the consequences of which jeopardized the functioning of the very health system-the district staff chose to involve the nurses, in charge of the HC, in the entire problem-solving process. This participative approach, involving different actors as partners, allowed to deepen the situation analysis and to elaborate solutions congruent with PHC principles and acceptable to all concerned.

    Translucent brown aggregates of calcium-carbonate crystals have been found in cores from the Zaire deep-sea fan (west equatorial Africa). The aggregates are well preserved but very friable. Upon storage they become yellowish white and cloudy and release water. Chemical, mineralogical (XRD), petrographical, crystal-morphological, and stable-isotope data demonstrate that the crystals have passed through three phases: (1) an authigenic carbonate phase, probably calcium carbonate, which is represented by the external habit of the present crystals; (2) a translucent brown ikaite phase (CaCO3·6H2O), unstable at temperatures above 5 °C; and (3) a phase consisting of calcite microcrystals that are poorly cemented and form a porous mass within the crystal form of the morphologically unchanged first phase. The transformation from the first phase into ikaite was probably a kinetic replacement. The transformation from ikaite into the third phase occurred because of storage at room temperature. The presence of ikaite is indicative of a low-temperature, anaerobic, organic-carbon-rich marine environment. Ikaite is probably the precursor of a great number of porous calcite pseudomorphs, and possibly also of many marine authigenic microcrystalline carbonate nodules.

    Several chemical and physical parameters are measured in forty seven stations, distributed on the most part of the hydrographic systems of Tunisia. Some parameters: temperature of the water (T), salinity (S, electric conductivity (CE), chloride (Cl-), total hardness (DT) and turbidity (TUR) show great variations in the Northern hydrographic systems. In these systems, the parameters (S, CE, Cl-, DT) are generally elevated in the tributaries of the south bank of the Medjerda, the North-East streams, Melah and Tine Streams which flow in the Ichkeul lake. The waters in these septentrional systems are sometimes very turbid. The waters of the meridional hydrological system are very clear. The resurgence thermal waters are characterized by the small amplitude of variations of the studied parameters. The waters are alkaline, generally very mineralized they are well oxygenized in the no-polluted stations.

    2016-10-01

    Full Text Available Introduction: Global travel is an efficient route of transmission for highly infectious pathogens and increases the chances of such pathogens moving from high disease-endemic areas to new regions. We describe the rapid and safe identification of the first imported case of Ebola virus disease in a traveler to Lagos, Nigeria, using conventional reverse transcription polymerase chain reaction (RT-PCR in a biosafety level (BSL-2 facility. Case presentation: On 20 July 2014, a traveler arrived from Liberia at Lagos International Airport and was admitted to a private hospital in Lagos, with clinical suspicion of Ebola virus disease. Methodology and Outcome: Blood and urine specimens were collected, transported to the Virology Unit Laboratory at the College of Medicine, University of Lagos, and processed under stringent biosafety conditions for viral RNA extraction. RT-PCR was set-up to query the Ebola, Lassa and Dengue fever viruses. Amplicons for pan-filoviruses were detected as 300 bp bands on a 1.5% agarose gel image; there were no detectable bands for Lassa and Dengue viral RNA. Nucleotide BLAST and phylogenetic analysis of sequence data of the RNA-dependent RNA polymerase (L gene confirmed the sequence to be Zaire ebolavirus (EBOV/Hsap/ NGA/2014/LIB-NIG 01072014; Genbank: KM251803.1. Conclusion: Our BSL-2 facility in Lagos, Nigeria, was able to safely detect Ebola virus disease using molecular techniques, supporting the reliability of molecular detection of highly infectious viral pathogens under stringent safety guidelines in BSL-2 laboratories. This is a significant lesson for the many under-facilitated laboratories in resource-limited settings, as is predominantly found in sub-Saharan Africa.

    The current Ebola virus disease (EVD) epidemic has killed more than all previous Ebola outbreaks combined and, even as efforts appear to be bringing the outbreak under control, the threat of reemergence remains. The availability of new whole-genome sequences from West Africa in 2014 outbreak, together with those from the earlier outbreaks, provide an opportunity to investigate the genetic characteristics, the epidemiological dynamics and the evolutionary history for Zaire ebolavirus (ZEBOV). To investigate the evolutionary properties of ZEBOV in this outbreak, we examined amino acid mutations, positive selection, and evolutionary rates on the basis of 123 ZEBOV genome sequences. The estimated phylogenetic relationships within ZEBOV revealed that viral sequences from the same period or location formed a distinct cluster. The West Africa viruses probably derived from Middle Africa, consistent with results from previous studies. Analysis of the seven protein regions of ZEBOV revealed evidence of positive selection acting on the GP and L genes. Interestingly, all putatively positive-selected sites identified in the GP are located within the mucin-like domain of the solved structure of the protein, suggesting a possible role in the immune evasion properties of ZEBOV. Compared with earlier outbreaks, the evolutionary rate of GP gene was estimated to significantly accelerate in the 2014 outbreak, suggesting that more ZEBOV variants are generated for human to human transmission during this sweeping epidemic. However, a more balanced sample set and next generation sequencing datasets would help achieve a clearer understanding at the genetic level of how the virus is evolving and adapting to new conditions.

    2018-03-09

    Kitovu Hospital in Masaka, Uganda, is a leading obstetric fistula repair centre in the country with the highest rates of fistula in the world. In this retrospective case review, the regional incidence and causative factors were studied in patients with vesicovaginal fistula (VVF) who were admitted at Kitovu Hospital. Fistula history included severity (ICIQ score), causes and outcomes of VVF were measured. Women suffered with symptoms of VVF for an average of 4.97 years with an average ICIQ severity score of 7.21. Patients travelled an average distance of 153 km and the majority travelled by public transport. Rates of prolonged labour were high. 69% of fistula-causing delivery resulted in stillbirth and 12% resulted in early neonatal death. Following surgery, 94% of patients were dry on discharge. Impact statement What is already known on this subject? Vesicovaginal fistula (VVF) is a severe, life-changing injury. Although largely eradicated from the Western world thanks to modern obstetric practice, VVF is still highly prevalent in developing countries where factors such as young childbearing age and poor access to emergency obstetric care increase the incidence (Wall et al. 2005 ). At the current rate of fistula repair, it is estimated that it would take 400 years to treat those already suffering with fistula, providing that no new cases emerged (Browning and Patel 2004 ). What do the results of this study add? The Ugandan women in this study reiterate tales of foetal loss, social isolation and epic journeys in search of fistula repair, as previously described in the literature. The study offers some hope for prompt help-seeking during labour and after fistulas are developed. It demonstrates the success of fistula repairs at Kitovu Hospital but highlights the paucity of service provision across Uganda. What are the implications of these findings for clinical practice and/or further research? Further epidemiological research is required to quantify the true

    1988-01-01

    During the 1980's in Karawa, Northwestern Zaire, a motion picture was produced which showed the interaction of the modern and traditional systems. The maternity center of the Karawa hospital was central to this effort. Traditional birth attendants (TBAs) became leading participants. Locally trained midwives were key trainers. The training and supervision programs had been ongoing for 2 years when Karawa was chosen as the movie site in 1986. The script was written by a midwife who had trained trainers of TBAs and TBAs themselves. All the steps in the selection, training, supervision, and supplying of TBAs in Karawa and its neighboring villages are included in the script. A Zairian team shot the script. The 5-member crew were employees of the Office Zairois de la Radio-Television (OZRT), the country's official television, radio, and film service.

    Full Text Available Ebola virus (EBOV can lead to severe hemorrhagic fever with a high risk of death in humans and other primates. To guide treatment and prevent spread of the viral infection, a rapid and sensitive detection method is required for clinical samples. Here, we described and evaluated a reverse transcription loop-mediated isothermal amplification (RT-LAMP method to detect Zaire ebolavirus using the nucleoprotein gene (NP as a target sequence. Two different techniques were used, a calcein/Mn2+ complex chromogenic method and real-time turbidity monitoring. The RT-LAMP assay detected the NP target sequence with a limit of 4.56 copies/μL within 45 min under 61°C, a similar even or increase in sensitivity than that of real-time reverse transcription-polymerase chain reaction (RT-PCR. Additionally, all pseudoviral particles or non- Zaire EBOV genomes were negative for LAMP detection, indicating that the assay was highly specific for EBOV. To appraise the availability of the RT-LAMP method for use in clinical diagnosis of EBOV, of 417 blood or swab samples collected from patients with clinically suspected infections in Sierra Leone, 307 were identified for RT-LAMP-based surveillance of EBOV. Therefore, the highly specific and sensitive RT-LAMP method allows the rapid detection of EBOV, and is a suitable tool for clinical screening, diagnosis, and primary quarantine purposes.

    During its work in Rakai district, CONCERN recognized that women lack property/inheritance rights, a situation which increases their vulnerability to HIV infection. Widows are being disinherited of all their properties, including their marital homes. Since many of these women lack both education and skills, their survival often depends upon either marrying again or engaging in sex work. Many women are ignorant of their rights under the national law. Lawyers from the Ugandan Women Lawyers Association help women and children understand their rights, but they do not provide continuously available services. CONCERN therefore initiated a program of community-based legal educators (paralegals) selected by village communities and recommended by local leaders. The paralegals must be over age 28 years, respected by the community, able to maintain confidentiality, and have participated in previous HIV/AIDS sensitization work. Selected candidates are subsequently trained by lawyers from a governmental ministry in the basics of the law pertaining to sexual abuse, marriage, inheritance, divorce, domestic violence, children's rights and responsibilities, and the legal system in Uganda, as well as referrals, gender sensitization, and adult education methods. The paralegals now provide awareness seminars in their communities which include brainstorming, role plays, use of picture codes, group discussions, and lectures.

    Tunisia is the only country that emerged from the Arab Spring as a democracy. However, Tunisian democracy is threatened by political divisions, economic problems, and the threat of terrorist attacks. We shed light on Tunisia's democratic prospects by examining (1) the degree to which major terrorist attacks in 2015 influenced Tunisian public opinion on democracy and (2) the extent to which preference for a democratic system affected opinions on the prospects for democracy in Tunisia. We use data from three waves of a nationwide survey conducted just before and just after Tunisia's first major terrorist attack, and just after the country's second major terrorist attack. We demonstrate that after the attacks the Tunisian public became less favourable toward democracy and less optimistic that Tunisia would soon be ready for it. Such scepticism was widespread, affecting people who preferred democracy as much as those who did not. We conclude that the prospects for Tunisian democracy are more precarious than is sometimes assumed. © 2017 Canadian Sociological Association/La Société canadienne de sociologie.

    Recent studies on date of birth of multiple sclerosis (MS) patients showed an association between month of birth and the risk of developing MS. This association has not been investigated in an African country. We aimed to determine if the risk of MS is associated with month of birth in Tunisia. Data concerning date of birth for MS patients in Tunisia (n = 1912) was obtained. Birth rates of MS patients were compared with all births in Tunisia matched by year of birth (n = 11,615,912). We used a chi-squared analysis and the Hewitt's non-parametric test for seasonality. The distribution of births among MS patients compared with the control population was not different when tested by the chi-squared test. The Hewitt's test for seasonality showed an excess of births between May and October among MS patients (p = 0.03). The peak of Births of MS patients in Tunisia was in July and the nadir in December. Our data does support the seasonality hypothesis of month of birth as risk factor for MS in Tunisia. Low vitamin D levels during pregnancy could be a possible explanation that needs further investigation. Copyright © 2015 Elsevier B.V. All rights reserved.

    2010-01-01

    Indoor radon measurements were carried out in 30 elementary schools in Tunis, the capital city of Tunisia, during the winter months of December 2008 to early March 2009. Two classrooms, one each from ground floor and first floor were chosen from each school making a total of 60 classrooms. In some of the classrooms, two detectors (open and closed) were used to measure the concentrations of radon as well as radon and its progeny to allow the calculations of the equilibrium factors. Nuclear track detectors type LR-115 (Kodalpha) were used for the measurements. The results show that the radon concentration levels are low in the range of 6-169 Bq m-3 with a mean value of 26.9 Bq m-3. The annual effective dose was found to vary between 0.025-0.715 mSv y-1 for teachers while the range for pupils was from 0.019-0.525 mSv y-1. These values are within the ICRP recommended values.

    Full Text Available The objective of this study was to examine the role of social security in fighting poverty in Metlaoui, Tunisia, using survey data collected between July 2012 and January 2014, covering 200 poor households. We used questionnaire data, which gave a thorough analysis of the reactions, behavior, and strategies adopted by poor households as a result of various forms of risk. Social security has an effect on a number of different areas, including health, education, housing, and income. Our methodology explored both complete and partial risk-sharing, to investigate the impact of social security schemes on the strategies adopted by households to cope with economic shocks. The estimation results of different models showed that social security could help social security-covered households choose less costly strategies to cope with risks. However, the role of social security remains insufficient, given that covered households had less confidence in its services and they adopted strategies of self-insurance or income smoothing. Overall, the results showed that social security plays an important role in Metlaoui, but it remains insufficient, especially for households that are not covered by social security and are suffering from heavy health expenditures.

    The objective of this study was to present a qualitative 'situation analysis' of the healthcare system in Tunisia, as it applies to management of cardiovascular disease (CVD) and diabetes. A primary concern was the institutional capacity to manage non-communicable diseases (NCDs). Research took place during 2010 (analysis of official documents, semi-structured interviews with key informants, and case studies in four clinics). Walt and Gilson's framework (1994) for policy analysis was used: content, actors, context, and process. Problems of integration and coordination have compounded funding pressures. Despite its importance in Tunisian healthcare, primary health is ill-equipped to manage NCDs. With limited funds, and no referral or health information system, staff morale in the public sector was low. Private healthcare has been the main development filling the void. This study highlights major gaps in the implementation of a comprehensive approach to NCDs, which is an urgent task across the region. In strategic planning, research on the health system is vital; but the capacity within Ministries of Health to use research has first to be built, with a commitment to grounding policy change in evidence.

    As in all developing countries, cities in Tunisia face serious problems of environmental pollution caused mainly by the inadequate and inefficient final disposal of their generated solid wastes. The Tunisian government launched a development program including the construction of landfills in the main cities and the closure of the contaminated sites issued from solid wastes landrising practice. The project of the Henchir El Yahoudia landfill restoration is the first experience in this programme. It has been suggested to convert the site to a green park and to implement an ornamental plant nursery. The whole surface of the landfill is approximately 100 ha from which 30 ha have been already transformed to an urban recreational area and the remaining 70 ha have to be characterized for the project extension. A field investigation by boring was conducted in order to define the geological and the hydrogeological conditions, the vertical and horizontal wastes layer extension, content and degree of decomposition and the composition and quantities of leachate and landfill gas. Representative samples of waste, soil, groundwater and leachate were collected for laboratory analyses. Several of these borings were converted to piezometers to define the flow regime in the site. The results showed that the biogas (CH4, H2S, and CO2), leachate and waste, distribution in the site is mainly affected by the temporal variation of the site operating method. The underlying fissured clay layer facilitated leachate infiltration into the groundwater where high BOD, COD and nitrogen concentrations were registered.

    2018-05-01

    This study analyzes large-scale controls on Uganda's rainfall. Unlike past work, here, a May-October season is used because of the year-round nature of agricultural production, vegetation sensitivity to rainfall, and disease transmission. The Uganda rainfall record exhibits steady oscillations of ˜3 and 6 years over 1950-2013. Correlation maps at two-season lead time resolve the subtropical ridge over global oceans as an important feature. Multi-variate environmental predictors include Dec-May south Indian Ocean sea surface temperature, east African upper zonal wind, and South Atlantic wind streamfunction, providing a 33% fit to May-Oct rainfall time series. Composite analysis indicates that cool-phase El Niño Southern Oscillation supports increased May-Oct Uganda rainfall via a zonal overturning lower westerly/upper easterly atmospheric circulation. Sea temperature anomalies are positive in the east Atlantic and negative in the west Indian Ocean in respect of wet seasons. The northern Hadley Cell plays a role in limiting the northward march of the equatorial trough from May to October. An analysis of early season floods found that moist inflow from the west Indian Ocean converges over Uganda, generating diurnal thunderstorm clusters that drift southwestward producing high runoff.

The male bulb shows a high degree of morphological similarity to that of L. gaucho from Brazil, but the proportions of the palpal segments and the general colouration of the body reveal significant differences between the two species. A distance analysis of the sequences of the mitochondrial gene cox1 reveals that the specimen from Tunisia shows high genetic distance from L. gaucho (more than 20%. The American species L. gaucho and L. laeta form a sister group to the Mediterranean representatives (L. rufescens and the Tunisian specimen.

    Over the past 30 years, Zaire and Sudan ebolaviruses have been responsible for large hemorrhagic fever (HF) outbreaks with case fatalities ranging from 53% to 90%, while a third species, Côte d'Ivoire ebolavirus, caused a single non-fatal HF case. In November 2007, HF cases were reported in Bundibugyo District, Western Uganda. Laboratory investigation of the initial 29 suspect-case blood specimens by classic methods (antigen capture, IgM and IgG ELISA) and a recently developed random-primed pyrosequencing approach quickly identified this to be an Ebola HF outbreak associated with a newly discovered ebolavirus species (Bundibugyo ebolavirus) distantly related to the Côte d'Ivoire ebolavirus found in western Africa. Due to the sequence divergence of this new virus relative to all previously recognized ebolaviruses, these findings have important implications for design of future diagnostic assays to monitor Ebola HF disease in humans and animals, and ongoing efforts to develop effective antivirals and vaccines.

    In Tunisia, at the extreme North of the African plate, the neotectonic context is largely influenced by the Eurasia-Africa convergence. The aim of this work is to characterize the neotectonic regime that affected this region during Quaternary. Field work investigations integrated with published data allowed to evidence a spatial-temporal variation of the tectonic stress regime during this period. The spatial repartition of the different types of Quaternary to historical deformation shows a North-South neotectonic zoning in Tunisia. After lower Pleistocene, the Tellian domain (Maghrebides) in the North and its Atlassic foreland in central Tunisia are affected by NNW-SSE compression. It generated E-W to NE-SW folds and reverse faults, well developed in the Plio-Quaternary molassic basins of Kechabta and Jendouba (Northern Tunisia). In the Atlas, the major E-W and N-S pre-existing faults have been reactivated with dextral and sinistral strike-slip kinematic respectively, associated to en-echelon folds (Kasserine, N-S Axis, Northern Chott belt...). After the Tyrrhenian, a submeridian compressional regime affected Northern Tunisia (e.g., Bizerte region) and was responsible for the E-W folding of marine strata. More to the South, in the Tunisian Sahel, transtensional tectonics with a NW-SE horizontal maximal compression (SHmax) deformed the Tyrrhenian marine series (Khénis, Skanès, Monastir…). During the Holocene and up to present-day times, N-S compressional tectonics reactivated the E-W pre-existing faults with a reverse movement in Northern Tunisia (Bulla Regia, Utica …), generating historical earthquakes. In Central Tunisia, the Aqueduct of Cherichira (built around AD 850) is displaced by a N-S normal fault. Similarly, a mosaic of a roman house is shifted by 10 cm, along a N-S sinistral normal fault. These deformations evidence a transtensional tectonic regime. During the Quaternary, all the NW-SE oriented grabens are subsiding (e.g., Bizerte Lake, Grombalia

    Approximately 2000 lives are lost in Uganda annually through road traffic accidents. In Kampala, they account for 39% of all injuries, primarily in males aged 16-44 years. They are a result of rapid motorization and urbanization in a country with a poor economy. Uganda's population is an estimated 28 million with a growth rate of 3.4% per year. Motorcycles and omnibuses, the main taxi vehicles, are the primary contributors to the accidents. Poor roads and drivers compound the situation. Twenty-three orthopaedic surgeons (one for every 1,300,000 people) provide specialist services that are available only at three regional hospitals and the National Referral Hospital in Kampala. The majority of musculoskeletal injuries are managed nonoperatively by 200 orthopaedic officers distributed at the district, regional and national referral hospitals. Because of the poor economy, 9% of the national budget is allocated to the health sector. Patients with musculoskeletal injuries in Uganda frequently fail to receive immediate care due to inadequate resources and most are treated by traditional bonesetters. Neglected injuries typically result in poor outcomes. Possible solutions include a public health approach for prevention of road traffic injuries, training of adequate human resources, and infrastructure development.

    The development of resistance to antimalarials is a major challenge for global malaria control. Artemisinin-based combination therapies, the newest class of antimalarials, are used worldwide but there have been reports of artemisinin resistance in Southeast Asia. In February through May 2013, we conducted open-label, nonrandomized therapeutic efficacy studies of artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) in Zaire and Uíge Provinces in northern Angola. The parasitological and clinical responses to treatment in children with uncomplicated Plasmodium falciparum monoinfection were measured over 28 days, and the main outcome was a PCR-corrected adequate clinical and parasitological response (ACPR) proportion on day 28. Parasites from treatment failures were analyzed for the presence of putative molecular markers of resistance to lumefantrine and artemisinins, including the recently identified mutations in the K13 propeller gene. In the 320 children finishing the study, 25 treatment failures were observed: 24 in the AL arms and 1 in the DP arm. The PCR-corrected ACPR proportions on day 28 for AL were 88% (95% confidence interval [CI], 78 to 95%) in Zaire and 97% (91 to 100%) in Uíge. For DP, the proportions were 100% (95 to 100%) in Zaire, and 100% (96 to 100%) in Uíge. None of the treatment failures had molecular evidence of artemisinin resistance. In contrast, 91% of AL late-treatment failures had markers associated with lumefantrine resistance on the day of failure. The absence of molecular markers for artemisinin resistance and the observed efficacies of both drug combinations suggest no evidence of artemisinin resistance in northern Angola. There is evidence of increased lumefantrine resistance in Zaire, which should continue to be monitored. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    2013-03-01

    Full Text Available The uprising in Tunisia, the occupation of public squares in Spain, the Occupy Wall Street movement, the global uprising on 15 October 2011 and the recent widespread demonstrations in Slovenia can be understood as the new generation of uprisings following the eruption of financial crisis. Those multitudinal expressions of indignation and quests for real democracy are expressions of the irreversible crisis of neoliberalism and representative democracy. From an examination of the defining traits of uprisings from Tunisia to Slovenia, one can define basic theoretical and practical dilemmas in the new ways of doing political encounters. These include the relationship between the social and political dimensions of uprisings, the relationship between heterogeneity and forms of political organization, how resistance against financialization prefigures emerging forms of direct democracy, how emerging movements address the issue of direct democracy and minority rights, and what theoretical practices can prevent the attenuation of the discourse of uprisings and enable the free production of enunciations.

  15. The seawater desalination needs of Tunisia after the year 2010

    2000-01-01

    The supply of drinking water for north and central Tunisia is guaranteed from surface water resources in the north and other subsurface resources. These resources will satisfy the water demand in this region until the year 2010 and 100000 m 3 /d by the year 2015. In the south of Tunisia, the water supply comes from local subsurface resources, including the lake water of the chotts. Maximum exploitation of these lakes, whose average salinity exceeds 2 g/l, has already been reached. Therefore, non-conventional resources such as desalination have become unavoidable if the water quality is to be improved and the resources are to be maximized. The needs of this region will reach 80000 m 3 /d by the year 2010. This deficit can only be met by the desalination of seawater. At present, about 60000 m 3 /d of water is desalinated in the country using the reverse osmosis process and electric energy. (author)

    Several Cirsium species are known for their uses in traditional medicine and consequently are studied for their phytochemical content and their biological activities. In the framework of a previous study conducted on eight extremophile plants from Tunisia, we highlighted that the crude methanolic extract of C. scabrum, a not investigated thistle, showed moderate but quite selective cytotoxic activity against the cancerous cell line J774 compared to the noncancerous cell line WI38 (IC50 = 11.5...

    Full Text Available The objective of this paper is to indicate the orientation of fiscal policy in Tunisia, using the structural budget balance, during the period 1972-2014. For this purpose, we estimate a structural VAR model consisting of the fiscal deficit to current GDP ratio and the volume of economic activity represented by the real GDP. We estimate bivariate structural VAR in order to decompose fiscal deficit fluctuations into different disturbances.

    This paper focuses on estimating wage differences between males and females in Tunisia by using the Oaxaca-Blinder decomposition, a technical that isolates wage gap due to characteristics, from wage gap due to discrimination against women. The data used in the analysis is obtained from the Tunisian Population and Employment Survey 2005. It is estimated that, the gender wage gap is about 19% and the results ascertain that the gender wage gap is mostly attributed to discrimination, especially t...

    Northern Tunisia is characterized by low deformation rates and low to moderate seismicity. Although instrumental seismicity reaches maximum magnitudes of Mw 5.5, some historical earthquakes have occurred with catastrophic consequences in this region. Aiming to improve our knowledge of active tectonics in Tunisia, we carried out both a quantitative morphometric analysis and field study in the north-western region. We applied different morphometric tools, like river profiles, knickpoint analysis, hypsometric curves and integrals and drainage pattern anomalies in order to differentiate between zones with high or low recent tectonic activity. This analysis helps identifying uplift and subsidence zones, which we relate to fault activity. Several active faults in a sparse distribution were identified. A selected sector was studied with a field campaign to test the results obtained with the quantitative analysis. During the fieldwork we identified geological evidence of recent activity and a considerable seismogenic potential along El Alia-Teboursouk (ETF) and Dkhila (DF) faults. The ETF fault could be responsible of one of the most devastating historical earthquakes in northern Tunisia that destroyed Utique in 412 A.D. Geological evidence include fluvial terraces folded by faults, striated and cracked pebbles, clastic dikes, sand volcanoes, coseismic cracks, etc. Although not reflected in the instrumental seismicity, our results support an important seismic hazard, evidenced by the several active tectonic structures identified and the two seismogenic faults described. After obtaining the current active tectonic framework of Tunisia we discuss our results within the western Mediterranean trying to contribute to the understanding of the western Mediterranean tectonic context. With our results, we suggest that the main reason explaining the sparse and scarce seismicity of the area in contrast with the adjacent parts of the Nubia-Eurasia boundary is due to its extended

    Using data from 433 firms operating along Uganda's charcoal and timber supply chains we investigate patterns of bribe payment and tax collection between supply chain actors and government officials responsible for collecting taxes and fees. We examine the factors associated with the presence and magnitude of bribe and tax payments using a series of bivariate probit and Tobit regression models. We find empirical support for a number of hypotheses related to payments, highlighting the role of queuing, capital-at-risk, favouritism, networks, and role in the supply chain. We also find that taxes crowd-in bribery in the charcoal market.

  4. Radiological quality of mineral waters battled in Tunisia

    There are approximately 60 natural water springs in Tunisia, but only 10 of them, mostly in the north, are legally authorized to be sold for bottled mineral water. The object of this study is to determine the radiological content of the mineral waters bottled in Tunisia by calculating the annual effective dose resulting from ingestion of the natural radionuclides in these waters. The results show that radioactivity is relatively low in the Tunisian mineral waters and is due essentially to uranium and radium picked up as the water passes through the deep rocks. Levels measured range from 3.3 to 2.5 mBq/L for 234 U. Radium levels range from 2.0 to 67.0 mBq/L for 226 Ra and from 2.0 to 30.2 mBq/L for 228 Ra. These levels are lower than those measured in many other regions over the world. For daily mineral water consumption over one year, the estimated effective dose level varies between 0.006 and 0.091 mSv for an adult and between 0.008 and 0.107 mSv for a 5-year old child. These results do not present a public health risk in Tunisia. This investigation enabled us to assess the contribution of bottler water to radiological exposure of natural origins. (author)

    As a first step in designing an AIDS prevention program at a large factory in Kinshasa, Zaire, we collected information on attitudes towards human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) from factory foremen and their wives. Trained moderators conducted twelve focus group discussions (from November through December 1987) that addressed knowledge, attitudes and beliefs about HIV infection and AIDS. In general, participants were familiar with HIV infection and AIDS and considered these conditions leading health problems in Kinshasa. Although participants had a fairly accurate understanding of the causes of HIV infection, modes of transmission and preventive measures, many myths and misconceptions existed. Many participants did not believe that condom use would consistently prevent infection through sexual intercourse. Participants strongly favored the counseling of seropositive persons but showed less consensus about whether the spouse of a seropositive person should be notified of the partner's test result. Participants predicted that couples in which one member is seropositive and the other is not would experience marital discord and friction with family, neighbors and co-workers. These findings were applied to the development of a counseling and educational program for seropositive factory employees and their spouses.

  6. Transcriptome Analysis of Circulating Immune Cell Subsets Highlight the Role of Monocytes in Zaire Ebola Virus Makona Pathogenesis

    Full Text Available Existing models of Ebola virus disease (EVD suggest antigen-presenting cells are initial targets of Zaire ebolavirus (ZEBOV. In vitro studies have shown that ZEBOV infection of monocytes and macrophages results in the production of inflammatory mediators, which may cause lymphocyte apoptosis. However, these findings have not been corroborated by in vivo studies. In this study, we report the first longitudinal analysis of transcriptional changes in purified monocytes, T-cells, and B-cells isolated from cynomolgus macaques following infection with ZEBOV-Makona. Our data reveal monocytes as one of the major immune cell subsets that supports ZEBOV replication in vivo. In addition, we report a marked increase in the transcription of genes involved in inflammation, coagulation, and vascular disease within monocytes, suggesting that monocytes contribute to EVD manifestations. Further, genes important for antigen presentation and regulation of immunity were downregulated, potentially subverting development of adaptive immunity. In contrast, lymphocytes, which do not support ZEBOV replication, showed transcriptional changes limited to a small number of interferon-stimulated genes (ISGs and a failure to upregulate genes associated with an antiviral effector immune response. Collectively, these data suggest that ZEBOV-infected monocytes play a significant role in ZEBOV-Makona pathogenesis and strategies to suppress virus replication or modify innate responses to infection in these cells should be a priority for therapeutic intervention.

    Ebola virus infection leads to severe hemorrhagic fever in human and non-human primates with an average case fatality rate of 50%. To date, numerous potential therapies are in development, but FDA-approved drugs or vaccines are yet unavailable. Ebola viral protein 24 (VP24) is a multifunctional protein that plays critical roles in the pathogenesis of Ebola virus infection, e.g. innate immune suppression by blocking the interaction between KPNA and PY-STAT1. Here we report macrocyclic peptide inhibitors of the VP24-KPNA5 protein-protein interaction (PPI) by means of the RaPID (Random non-standard Peptides Integrated Discovery) system. These macrocyclic peptides showed remarkably high affinity to recombinant Zaire Ebola virus VP24 (eVP24), with a dissociation constant in the single digit nanomolar range, and could also successfully disrupt the eVP24-KPNA interaction. This work provides for the first time a chemical probe capable of modulating this PPI interaction and is the starting point for the development of unique anti-viral drugs against the Ebola virus.

    Infections with filoviruses in humans are highly virulent, causing hemorrhagic fevers which result in up to 90% mortality. In addition to natural infections, the ability to use these viruses as bioterrorist weapons is of significant concern. Currently, there are no licensed vaccines or therapeutics available to combat these infections. The pathogenesis of disease involves the dysregulation of the host's immune system, which results in impairment of the innate and adaptive immune responses, with subsequent development of lymphopenia, thrombocytopenia, hemorrhage, and death. Questions remain with regard to the few survivors of infection, who manage to mount an effective adaptive immune response. These questions concern the humoral and cellular components of this response, and whether such a response can be elicited by an appropriate prophylactic vaccine. The data reported herein describe the production and evaluation of a recombinant subunit Ebola virus vaccine candidate consisting of insect cell expressed Zaire ebolavirus (EBOV) surface glycoprotein (GP) and the matrix proteins VP24 and VP40. The recombinant subunit proteins are shown to be highly immunogenic in mice, yielding both humoral and cellular responses, as well as highly efficacious, providing up to 100% protection against a lethal challenge with live virus. These results demonstrate proof of concept for such a recombinant non-replicating vaccine candidate in the mouse model of EBOV which helps to elucidate immune correlates of protection and warrants further development.

    There is little known concerning the disease caused by Zaire ebolavirus (ZEBOV) when inhaled, the likely route of exposure in a biological attack. Cynomolgus macaques, rhesus macaques, and African green monkeys were exposed to aerosolized ZEBOV to determine which species might be the most relevant model of the human disease. A petechial rash was noted on cynomolgus and rhesus macaques after fever onset but not on African green monkeys. Fever duration was shortest in rhesus macaques (62.7 ± 16.3 h) and longest in cynomolgus macaques (82.7 ± 22.3h) and African green monkeys (88.4 ± 16.7h). Virus was first detectable in the blood 3 days after challenge; the level of viremia was comparable among all three species. Hematological changes were noted in all three species, including decreases in lymphocyte and platelet counts. Increased blood coagulation times were most pronounced in African green monkeys. Clinical signs and time to death in all three species were comparable to what has been reported previously for each species after parenteral inoculation with ZEBOV. These data will be useful in selection of an animal model for efficacy studies. Published by Elsevier Masson SAS.

    2010-07-01

    Full Text Available This article deals with the statistical data and analysis con-cerning poverty among the young people in Uganda. The poverty is continuously ascending, with the most affected region being Northern Uganda. The major cause of poverty in Uganda has been the “South-North divide” fuelled by poor political leadership, that divides people along the lines of politics and ethnicity. Poverty has caused many young people of Northern Uganda to resort to rebellion against the government currently in power. This has led to unending political instability and civil strife most especially in Northern Uganda. In this article atten-tion is given to the conflict in Northern Uganda and attempts are made to propose some amicable resolutions. The discussion includes the current poverty scenario in Northern Uganda and possible strategies for reducing the poverty rate that has caused much damage in Northern Uganda.

    In 1976, the first cases of Ebola virus disease in northern Democratic Republic of the Congo (then referred to as Zaire) were reported. This article addresses who was responsible for recognizing the disease; recovering, identifying, and naming the virus; and describing the epidemic. Key scientific approaches used in 1976 and their relevance to the 3-country (Guinea, Sierra Leone, and Liberia) West African epidemic during 2013-2016 are presented. Field and laboratory investigations started soon after notification, in mid-September 1976, and included virus cell culture, electron microscopy (EM), immunofluorescence antibody (IFA) testing of sera, case tracing, containment, and epidemiological surveys. In 2013-2016, medical care and public health work were delayed for months until the Ebola virus disease epidemic was officially declared an emergency by World Health Organization, but research in pathogenesis, clinical presentation, including sequelae, treatment, and prevention, has increased more recently. Filoviruses were cultured and observed by EM in Antwerp, Belgium (Institute of Tropical Medicine); Porton Down, United Kingdom (Microbiological Research Establishment); and Atlanta, Georgia (Centers for Disease Control and Prevention). In Atlanta, serological testing identified a new virus. The 1976 outbreak (280 deaths among 318 cases) stopped in 2 years. Transmission indices (R 0 ) are higher in all 3 countries than in 1976. An international commission working harmoniously in laboratories and with local communities was essential for rapid success in 1976. Control and understanding of the recent West African outbreak were delayed because of late recognition and because authorities were overwhelmed by many patients and poor community involvement. Despite obstacles, research was a priority in 1976 and recently. Published by Oxford University Press for the Infectious Diseases Society of America 2016.

    The recent Zaire Ebola virus (EBOV) outbreak in West Africa illustrates clearly the need for additional studies with humans and animals to elucidate the ecology of Ebola viruses (EBVs). In this study, we developed a serological assay based on the Luminex technology. Nine recombinant proteins representing different viral regions (nucleoprotein [NP], 40-kDa viral protein [VP40], and glycoprotein [GP]) from four of the five EBV lineages were used. Samples from 94 survivors of the EBOV outbreak in Guinea and negative samples from 108 patients in France were used to calculate test performance for EBOV detection and cross-reaction with other Ebola virus lineages. For EBOV antibody detection, sensitivities of 95.7%, 96.8%, and 92.5% and specificities of 94.4%, 95.4%, and 96.3% for NP, GP, and VP40, respectively, were observed. All EBOV-negative samples that presented a reaction, except for one, interacted with a single antigen, whereas almost all samples from EBOV survivors were simultaneously reactive with NP and GP (90/94) or with NP, GP, and VP40 (87/94). Considering as positive for past EBOV infection only samples that reacted with EBOV NP and GP, sensitivity was 95.7% and specificity increased to 99.1%. Comparing results with commercial EBOV NP and GP enzyme-linked immunosorbent assays (ELISAs; Alpha Diagnostic, San Antonio, TX), lower sensitivity (92.5%) and high specificity (100%) were observed with the same positivity criteria. Samples from EBOV survivors cross-reacted with GP from Sudan Ebola virus (GP-SUDV) (81.9%), GP from Bundibugyo Ebola virus (GP-BDBV) (51.1%), GP from Reston Ebola virus (GP-RESTV) (9.6%), VP40-SUDV (76.6%), and VP40-BDBV (38.3%). Overall, we developed a sensitive and specific high-throughput serological assay, and defined an algorithm, for epidemiological surveys with humans.

    The Ebola viruses (EBOVs) VP35 protein is a multifunctional major virulence factor involved in EBOVs replication and evasion of the host immune system. EBOV VP35 is an essential component of the viral RNA polymerase, it is a key participant of the nucleocapsid assembly and it inhibits the innate immune response by antagonizing RIG-I like receptors through its dsRNA binding function and, hence, by suppressing the host type I interferon (IFN) production. Insights into the VP35 dsRNA recognition have been recently revealed by structural and functional analysis performed on its C-terminus protein. We report the biochemical characterization of the Zaire ebolavirus (ZEBOV) full-length recombinant VP35 (rVP35)-dsRNA binding function. We established a novel in vitro magnetic dsRNA binding pull down assay, determined the rVP35 optimal dsRNA binding parameters, measured the rVP35 equilibrium dissociation constant for heterologous in vitro transcribed dsRNA of different length and short synthetic dsRNA of 8bp, and validated the assay for compound screening by assessing the inhibitory ability of auryntricarboxylic acid (IC(50) value of 50μg/mL). Furthermore, we compared the dsRNA binding properties of full length wt rVP35 with those of R305A, K309A and R312A rVP35 mutants, which were previously reported to be defective in dsRNA binding-mediated IFN inhibition, showing that the latter have measurably increased K(d) values for dsRNA binding and modified migration patterns in mobility shift assays with respect to wt rVP35. Overall, these results provide the first characterization of the full-length wt and mutants VP35-dsRNA binding functions. Copyright © 2012 Elsevier B.V. All rights reserved.

    Morocco and Tunisia are both net-wheat importing countries, which experience fluctuations in production due to drought. Knowledge of food supply is critical for the local governments' understanding of food security and to re-assure the population regarding food availability. Tunisia was the epicenter for the event known as the "Arab Spring." Although the Arab Spring had several societal components, chronic uncertainty in the governments' reliability raised concerns about food supply and food availability despite the government's policy responses. Due to its importance for geopolitical as well as market opportunity reasons, in March and April of 2017, analysts from the USDA Foreign Agricultural Service (FAS) traveled to Morocco and Tunisia to conduct crop assessment. Fieldwork data collection is necessary for us as crop analysts to use our convergence of evidence approach, which includes ground information, satellite imagery, meteorological information and reports from our offices abroad. During this trip, analysts used the new mobile application from the National Geospatial Intelligence Agency (NGA) called MAGE to collect fieldwork data for crop classification. Using the several thousand training data collected through the mobile application and by leveraging satellite data within Google Earth Engine, an in-season crop mask was created. The final product was delivered to the team just a few days after returning to USDA Washington and was used in the first wheat production estimate of the season released May 10, 2017. The final product helps analysts determine an experimental in-season area estimation and to focus our other remote sensing tools and products on our areas of interest.

    Health care financing provides the resources and economic incentives for operating health systems and is a key determinant of health system performance. Equitable financing is based on: financial protection, progressive financing and cross-subsidies. This paper describes Uganda's health care financing landscape and documents the key equity issues associated with the current financing mechanisms. We extensively reviewed government documents and relevant literature and conducted key informant interviews, with the aim of assessing whether Uganda's health care financing mechanisms exhibited the key principles of fair financing. Uganda's health sector remains significantly under-funded, mainly relying on private sources of financing, especially out-of-pocket spending. At 9.6 % of total government expenditure, public spending on health is far below the Abuja target of 15% that GoU committed to. Prepayments form a small proportion of funding for Uganda's health sector. There is limited cross-subsidisation and high fragmentation within and between health financing mechanisms, mainly due to high reliance on out-of-pocket payments and limited prepayment mechanisms. Without compulsory health insurance and low coverage of private health insurance, Uganda has limited pooling of resources, and hence minimal cross-subsidisation. Although tax revenue is equitable, the remaining financing mechanisms for Uganda are inequitable due to their regressive nature, their lack of financial protection and limited cross-subsidisation. Overall, Uganda's current health financing is inequitable and fragmented. The government should take explicit action to promote equitable health care financing by establishing pre-payment schemes, enhancing cross-subsidisation mechanisms and through appropriate integration of financing mechanisms.

    Sheep pox, a well-known endemic capripox infection, has significant impacts on small ruminant populations in Tunisia. It is responsible for high economic losses throughout North Africa due to its enzootic nature and to the active animal transhumance existing in some governorates in Tunisia. The aim of this review was to analyse data gathered on annual vaccination campaigns designed to control its spread by reducing the level of endemicity and to describe diagnostic and management tools adapted to the Tunisian situation. Seasonal, temporal and spatial distributions of sheep pox outbreaks, as well as related clinical features, were found. It was concluded from this review that establishing strong herd immunization through individual animal immunization, creating adequate infrastructure, increasing awareness among breeders, setting up a field-based surveillance network and improving routine diagnostic methods need to be the major components of a programme to eradicate the disease. It was also felt that cost-benefit analyses of the surveillance and control strategies used would help in controlling its persistence. © 2017 Blackwell Verlag GmbH.

    A new picornavirus, named human Cosavirus (HCoSV) was isolated recently from stools of children with acute flaccid paralysis (AFP) and healthy children in Pakistan and Afghanistan. Since then, it was also isolated from patients from other countries. Five species are presently identified forming a new genus in the Picornaviridae family. This study reports the detection of HCoSV in stool specimens collected as part of the National Poliovirus surveillance Program in Tunisia, between 2011 and 2012, from patients with AFP and healthy individuals among their contacts. One hundred and ninety four stool samples were investigated by RT-PCR in the 5' non-coding region of the genome. A total of 64 specimens (33%) tested positive for HCoSV. HCoSV positive specimens were found in 36 cases with neurological syndromes and 28 of their healthy contacts. The highest rate of HCoSV infection (62.5%) occurred in children younger than 6 years of age. The sampling date of stool specimens suggested that HCoSV infection occurred regularly over time. Also, the sampling origin of stool specimen showed that HCoSV infection was detected in almost all the governorates of Tunisia from the North to the South of the country. This study is the first report of HCoSV prevalence in the North African region. It contributes to a better knowledge on the geographic distribution and the epidemiology of these viruses. © 2015 Wiley Periodicals, Inc.

    Tunisia is a country with a high vocational agricultural orientation. It continues to promote production and gives incentives to construct storage and processing installations in order to meet the food demand of the growing population. This policy is part of a global development program aimed at reaching a food security system. This system is based not only on increasing production but also on the improvement of the storage and processing capacities existing in the country, whether modern or traditional, taking in consideration the food commodities and the region concerned. Food preservation by irradiation is an alternative to improve and reinforce our food security system, since it is considered as a way to protect commodities from spoilages and also to promote shelf life and improve hygienic qualities. The products which are concerned by decreasing losses are mainly potatoes, onions garlic, dates, nuts, etc. Hygiene improvement will concern poultry products for our growing tourist business. And, shelf extension concerns our exports of sea product to the european community. Within this scope the government of tunisia has submitted a proposal to install a pilot unit to carry out preliminary work toward the introduction of an industrial unit. The international atomic energy agency has accepted the proposal and is looking for funds for the implementation. The government has recently pledged 60.000 tunisian dinars to do the required engineering studies of the unit. 4 tabs

    The Landsat mosaic of Tunisia funded by USAID for the Remote Sensing Laboratory, Soils Division, Ministry of Agriculture, Tunisia, was completed by the USGS in September 1983. It is a mixed mosaic associating digital corrections and enhancements to manual mosaicking and corresponding to the Tunisian request for high resolution and the limited available funds. The scenes were processed by the Environmental Research Institute of Michigan, resampling the data geodesically corrected to fit the Universal Transverse Mercator projection using control points from topographic maps at 1:50,000 and 1:100,000 scales available in the U. S. The mosaicking was done in the Eastern Mapping Center under the supervision of the Graphic Arts System Section. The three black and white mosaics were made at the 1:1,000,000 scale and various products generated. They included color film positives at 1:2,000,000 and 1:4,000,000 scales reproducible in the Remote Sensing Laboratory in Tunis and corresponding color prints as well as tricolor prints at various scales from 1:500,000 to 1:2,000,000.

    Diagnosis of rickettsioses had largely benefited from the development of molecular techniques. Unfortunately, in Tunisia, despite the large number of rickettsial cases registered every year, the Rickettsia species remain unidentified. In this study, we aimed to detect the Rickettsia species in clinical samples using molecular tests. A study was established to analyze skin biopsies, cutaneous swabs, and cerebrospinal fluid samples taken from clinically suspected patients to have rickettsial infection. Two molecular techniques were used to detect Rickettsia DNA: quantitative real time PCR (qPCR) and reverse line blot test (RLB). An analysis of the RLB hybridization assay results revealed the presence of Rickettsia DNA in skin biopsies (40.6%) and swabs (46.7%). Rickettsia conorii was the most prevalent identified species among tested samples. Other species of interest include Rickettsia typhi and Rickettsia massiliae. Using qPCR positivity rates in skin biopsies was 63.7% against 80% in swabs. R. conorii was the most frequently detected species, followed by R. typhi. The agreement between the two techniques was 68.6% (kappa=0.33). Molecular tests, especially using specific probes qPCR, allow for a rapid, better and confident diagnosis in clinical practice. They improve the survey of Mediterranean spotted fever which is considered to be the most important rickettsial infection in humans in Tunisia. Copyright © 2016 Elsevier GmbH. All rights reserved.

    The consequences of the 2013-16 Ebola Zaire virus disease epidemic in West Africa were grave. The economies, healthcare systems and communities of Guinea, Sierra Leone and Liberia were devastated by over 18 months of active Ebola virus transmission, followed by sporadic resurgences potentially related to sexual transmission by survivors with viral persistence in body fluids following recovery. The need to develop and implement strategies to prevent and mitigate future outbreaks is now beyond dispute. The potential for unpredictable outbreaks of indeterminate duration, and control challenges posed by the possibility of sporadic re-emergence, mean that implementation of an effective vaccination program for outbreak containment necessitates a vaccine providing durable immunity. Heterologous prime-boost vaccine regimens deliver the same or similar antigens through different vaccine types, the first to prime and the second to boost the immune system. Ad26.ZEBOV/MVA-BN-Filo is an investigational Ebola Zaire vaccine regimen that uses this heterologous prime-boost approach. Preliminary Phase 1 data suggest that Ad26.ZEBOV/MVA-BN-Filo confers durable immunity for at least 240 d and is well-tolerated with a good safety profile. This regimen may therefore be suitable for prophylactic use in a regional or targeted population vaccination strategy, and could potentially aid prevention and control of future Ebola outbreaks.

    Introduction In 2010, the World Health Organization released a new cholera vaccine position paper, which recommended the use of cholera vaccines in high-risk endemic areas. However, there is a paucity of data on the burden of cholera in endemic countries. This article reviewed available cholera surveillance data from Uganda and assessed the sufficiency of these data to inform country-specific strategies for cholera vaccination. Methods The Uganda Ministry of Health conducts cholera surveillance to guide cholera outbreak control activities. This includes reporting the number of cases based on a standardized clinical definition plus systematic laboratory testing of stool samples from suspected cases at the outset and conclusion of outbreaks. This retrospective study analyzes available data by district and by age to estimate incidence rates. Since surveillance activities focus on more severe hospitalized cases and deaths, a sensitivity analysis was conducted to estimate the number of non-severe cases and unrecognized deaths that may not have been captured. Results Cholera affected all ages, but the geographic distribution of the disease was very heterogeneous in Uganda. We estimated that an average of about 11,000 cholera cases occurred in Uganda each year, which led to approximately 61–182 deaths. The majority of these cases (81%) occurred in a relatively small number of districts comprising just 24% of Uganda's total population. These districts included rural areas bordering the Democratic Republic of Congo, South Sudan, and Kenya as well as the slums of Kampala city. When outbreaks occurred, the average duration was about 15 weeks with a range of 4–44 weeks. Discussion There is a clear subdivision between high-risk and low-risk districts in Uganda. Vaccination efforts should be focused on the high-risk population. However, enhanced or sentinel surveillance activities should be undertaken to better quantify the endemic disease burden and high-risk populations

  18. [Plague in Zaire].

    1994-01-01

    Two endemic foci of plague have been discovered in Zaïre, the first in the Ituri in 1928, the other in North-Kivu in 1938. They are situated in the region of the great East-African Rift and are adjacent to the Ugandan focus, identified in 1877. A strict surveillance of these endemic foci makes it possible to state that, between 1928 and 1959, 632 cases of plague have been diagnosed in the Ituri, or 20 a year, and 190 in the N-Kivu, or 8 a year. Since then several flare ups have been notified. This situation is very remote from the "black death" concept. Yersinia pestis presents, besides its bipolar staining, many other characteristics such as the indispensable presence of iron to produce virulence, or the fermentation of glycerine and reduction of nitrates as parameters for the identification of 3 biovars, corresponding with a specific geographic distribution: antiqua, medievalis, orientalis or maritima. The antigenic structure has been discussed and also the role of plasmids. Plague is a disease of rats, a variegated gathering of rodents with different degrees of tolerance and sensitiveness to Y.pestis, living in a frail equilibrium. The multimammate houserat was in the Ituri the principal agent until the black rat Rattus rattus invaded the region and a new balance came into being. The frequent changes in taxonomy of Mastomys caused uncertainties. The transmission is due to fleas subject to a blocking of their ventriculum by Y.pestis. Fleas play an active part in the process. Man is only a casual intruder. The pathogenicity is related to its invasiveness and its intracellular localization in macrophages and other R.E. cells, in which Y.pestis can survive. The bubo is characteristic of the disease. In Zaïre a septicaemic tendency has been observed, with a possible involvement of the C.N.S. and of the lungs. The latter may produce among the surrounding relatives primary pneumonic plague. The clinical diagnosis ought to be confirmed by bacteriologic investigation of the puncture fluid of the bubo, the blood, and when necessary the C.S.F. or the sputum by culture and/or animal inoculation. The treatment became very efficient since the availability of sulfamides and later antibiotics: aminoglycosides, chloramphenicol, tetracyclines. A timely administration ensures practically recovery. As soon as Y.pestis was identified vaccination was put into practice and in the first place by killed germs (Haffkine's lymph) to day with formalized F1, for mass vaccination live attenuated strains were used: Tjiwidej (Otten), E.V. (Girard), K120 (Grasset).(ABSTRACT TRUNCATED AT 400 WORDS)

    Polonium-210 is a radio-isotopes natural α emitter, it cans be found in tobacco with a significant range. The high activity of 210 Po in tobacco and cigarettes causes the absorption of a high dose of alpha radiation that caused probably lung cancer, the objective of this study is to estimate the activity of 210 Po in tobacco matrix. Thirteen samples of cigarettes consumed in tunisia were experimented to determine the activity of this radionuclide. The PIPS, a silicon semiconductor, is used as on α spectrometry detector for the detection of 210 Po in all of our samples. The final results showed a high radioactivity of 210 Po from 11.77 to 25.31 mBq/g. We conclude that the effective annual average is estimated at 106.53 μSv / year.

    Nuclear medicine is concerned with the utilisation of radioactivity in vivo or in vitro for diagnostic or therapeutic purposes. In Tunisia, there are four public departments of nuclear medicine and seven private clinics. 50% of the population is localized in the north, which justifies the existence of 7 public and private departments of nuclear medicine with nine gamma cameras in this region. In the south, there are 30 pour cent of the population that goes to Sfax and 20 pour cent to Sousse where we count two departments with gamma cameras in public services and one in the private sector. The nuclear medicine services in the public sector have 4 SPECT / CT. Siemens is the leading provider of gamma cameras and occupies 73 pour cent of market share, subsequently ranks SMV (13 pour cent) and (GE and GAEDE) have the same proportion of the market share (7 pour cent). For radio-protected rooms, there is a single center with a single chamber from four public services. On the other hand, there are 2/7 private centers that are equipped with five radio-protected electrically rooms. Concerning the human resources, there are 26 doctors and 24 technicians in the public sector. The private sector has 6 doctors and 12 technicians. In 2012, there has been 22000 examinations (diagnostic and therapeutic procedures) in which 14,600 in nuclear medicine departments of public hospitals. Bone scintigraphy ranks first, with a relative frequency of 40-80 pour cent thereafter ranks renal scintigraphy (10-15 pour cent) and then the thyroid scintigraphy (8-12 pour cent). The waiting period is a major problem, especially in the public sector. Taking as an example, for the therapy of thyroid, injection of 100 mCi of I-131 requires a period of waiting more than six months and waiting more than three months for the bone scan. The second problem for patient with cancer is the distance, there are 11 centers concentrated in 3 coastal cities and none in the inner areas of the country, no regional

    Today there are many coastal communities that are home to navigators who use stars for position finding at night; I was, however, unaware of this fact when I began researching celestial navigation practices in 1997. My project focused on three communities: the Moce Islanders of Fiji, the Kerkennah Islanders in Tunisia, and the U.S. Navy officers and students at the United States Naval Academy, Annapolis, Maryland. My goal was to answer the question of why people continue to navigate by the stars, but also to understand the role of technology in their navigation practices. Using anthropology techniques of ethnography including participant observation, formal and informal interviews, audio and videotaping, I gathered data over five years at the three communities. I began by learning the details of how they use the stars for navigation. Next, I learned about who did the navigation and where they learned to navigate. I gathered opinions on various navigation aids and instruments, and opinions about the future of using the stars for navigation. I listened to the stories that they told about navigating. In the United States I worked in English, in Fiji, in Fijian and English, and in Tunisia, French and English. For the formal interviews I worked with translators. The navigators use stars for navigating today but the future of their techniques is not certain. Though practiced today, these celestial navigation traditions have undergone and continue to undergo changes. New navigational technologies are part of the stimulation for change, thus 'a meeting of different worlds' is symbolized by peoples encounters with these technologies.

    Forty wild canids including 31 golden jackals (Canis aureus Linné, 1758) and 9 red foxes (Vulpes vulpes Linné, 1758) collected between 2008 and 2011 in the northeast, northwest and center of Tunisia were necropsied and examined for intestinal helminth parasites. All jackals and foxes were found infected with a prevalence rate of 95% for cestodes, 82.5% for nematodes and 7.5% for acanthocephalans. A total of twelve helminth species were recorded in red foxes: cestodes, Dipylidium caninum (55.6%), Diplopylidium noelleri (55.6%), Mesocestoïdes lineatus (55.6%), Mesocestoïdes litteratus (33%), Mesocestoïdes corti (22%); nematodes, Ancylostoma caninum (11%), Uncinaria stenocephala (44%), Spirura rytipleurites (11%), Trichuris vulpis (33%), Pterygodermatites affinis (67%), Oxynema linstowi (33%) and the acanthocephalan Macracanthorhynchus hirudinaceus (22%). The fifteen recovered helminth species in jackals were Echinococcus granulosus (9.7%), D. caninum (16%), D. noelleri (16%), M. lineatus (74%), M. litteratus (23%), M. corti (12.9%), Taenia pisiformis (3.2%), Taenia spp. (19%), Toxocara canis (16%), Toxascaris leonina (6.5%), A. caninum (9.7%), U. stenocephala (68%), P. affinis (6.5%), O. linstowi (3.2%) and Macracanthorhynchus hirudinaceus (3.2%). This is the first report on the presence of P. affinis, D. noelleri and O. linstowi in Tunisia. E. granulosus was found in young jackals, aged less than 4 years old, with a higher abundance in females (8.9 worms). M. lineatus presented the highest mean intensity of 231.86 and 108.8 tapeworms respectively in jackals and foxes. Canids from the northwest region had the highest prevalence (77.5%) and highest intensity (243.7) of helminth species compared to those from the northeast and central areas. U. stenocephala and O. linstowi had the highest mean intensity for nematodes in both jackals and foxes at 14.3 and 88 worms respectively. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available The Numidian flysch consists of a thick turbiditic sandy and clayey formation of Oligocene-Lower Miocene age which outcrops largely in northern Tunisia. Concerning the relationship between the Numidian formation and its «substratum», two hypothesis are discussed : i allochtonous Numidian units (tangential abnormal contact ; ii autochtonous Numidian units (sedimentary contact : locally downlap. Detailed investigation undertaken in the study area, based on the survey and the dating of lithological logs, coupled with geodynamic and petrogenetic events, lead to the following results : i absence of tangential tectonic contact in the base of Numidian series ; ii a significant Tertiary tectonics attested by several phases. Moreover, the Numidian siliciclastic series are affected, like the other Tertiary formations in the North of Tunisia, by south-east ward deep-seated thrusts, oriented N50-60.El flysch Numidiense es una formación arenisco-arcillosa de gran espesor y de edad Oligoceno-Mioceno inferior, que aflora en el norte de Túnez. La naturaleza del contacto basal de esta formación ha suscitado numerosas discusiones. De ellas destacan dos hipótesis: 1 las unidades numidienses alóctonas se apoyan en forma de contacto anormal tangencial, y 2 se trata de unidades autóctonas (contacto sedimentario normal, a veces de tipo "downlap".El levantamiento de cortes litológicos detallados y su datación, combinado con datos de tipo geodinámico y petrogenético, ha permitido confirmar la ausencia de un contacto tectónico tangencial en la base del Numidiense y por el contrario, establecer la existencia de una significativa tectónica terciaria desarrollada en varias fases. Asi, las series siliciclásticas Numidienses se ven afectadas, como otras formaciones terciarias del norte de Túnez, por cabalgamientos de vergencia SE.

    Anecdotal evidence on hidden inequity in health care in North African countries abounds. Yet firm empirical evidence has been harder to come by. This article fills the gap. It presents the first analysis of equity in the healthcare system using the particular case of Tunisia. Analyses are based on an unusually rich source of data taken from the Tunisian HealthCare Utilization and Morbidity Survey. Payments for health care are derived from the total amount of healthcare spending which was incurred by households over the last year. Utilization of health care is measured by the number of physical units of two types of services: outpatient and inpatient. The measurement of need for health care is apprehended through a rich set of ill-health indicators and demographics. Findings are presented and compared at both the aggregate level, using the general summary index approach, and the disaggregate level, using the distribution-free stochastic dominance approach. The overall picture is that direct out-of-pocket payments, which constitute a sizeable share in the current financing mix, emerge to be a progressive means of financing health care overall. Interestingly, however, when statistical testing is applied at the disaggregate level progressivity is retained over the top half of the distribution. Further analyses of the distributions of need for--and utilization of--two types of health care--outpatient and inpatient--reveal that the observed progressivity is rather an outcome of the heavy use, but not need, for health care at the higher income levels. Several policy relevant factors are discussed, and some recommendations are advanced for future reforms of the health care in Tunisia.

  1. Accessing diabetes care in rural Uganda

    DEFF Research Database (Denmark)

    Nielsen, Jannie; Bahendeka, Silver K.; Bygbjerg, Ib C.

    2017-01-01

    Non-communicable diseases including type 2 diabetes (T2D) are increasing rapidly in most Sub-Saharan African (SSA) countries like Uganda. Little attention has been given to how patients with T2D try to achieve treatment when the availability of public health care for their disease is limited......, as is the case in most SSA countries. In this paper we focus on the landscape of availability of care and the therapeutic journeys of patients within that landscape. Based on fieldwork in south-western Uganda including 10 case studies, we explore the diabetes treatment options in the area and what it takes...... to access the available treatment. We analyse the resources patients need to use the available treatment options, and demonstrate that the patients’ journeys to access and maintain treatment are facilitated by the knowledge and support of their therapy management groups.

    This book is about engendering local governance. It explores the euphoria with which Uganda's decentralization policy took centre stage as a sufficient driver to engender local development responsiveness and accountability. Using a case study of AFARD in Nebbi district, it shows first that decentralized governance is gendered and technocratic as grassroots women's effective participation is lacking. Second, it shows that the insertion of women in local governance is merely a symbolic politica...

  3. The complexities of educating nurses in Uganda.

    Andrews, C M; Rottman, C J; Lematia, R M

    1996-01-01

    Imagine that you are a woman living in rural Uganda. Your husband has returned to the city to work as a manual labourer. With a toddler playing alongside, you work long hot hours in the field to provide for your family. For weeks you have run a low-grade fever which you suspect is related to your advancing pregnancy. As traditional medicines have provided no relief, you sacrifice a day in the field and wait in line for care at a medical clinic outpost that is staffed one day a week. Nearing your turn, you hear a rumour that the government now requires payment in advance for care. As you and most of the others waiting in line do not have money, you leave together and arrange to pool resources from a community project so that you can all return to the clinic next week. Your pain increases and your productivity goes down. When the clinic day finally comes, the nurse does not show up because her own children need food and she prefers to earn ready cash by selling crafts in the market rather than work at the clinic for barely subsistence pay. The story does not end here, nor does that of countless other women in Uganda, including the caregivers. The difficulties are ongoing. And meeting health needs in Uganda as in many countries in Sub-Sahara Africa is complex and challenging.

  4. Antiproliferative and Antibacterial Activities of Cirsium scabrum from Tunisia

    Full Text Available Several Cirsium species are known for their uses in traditional medicine and consequently are studied for their phytochemical content and their biological activities. In the framework of a previous study conducted on eight extremophile plants from Tunisia, we highlighted that the crude methanolic extract of C. scabrum, a not investigated thistle, showed moderate but quite selective cytotoxic activity against the cancerous cell line J774 compared to the noncancerous cell line WI38 (IC50 = 11.53 μg/ml on J774, IC50 = 29.89 µg/ml on WI38, and selectivity index = 2.6. In the current study, the partitions of the leaves of C. scabrum were analyzed for their antiproliferative activity on the same cell lines. From the most active petroleum ether partition, we isolated four triterpenoids including lupeol, taraxasterol acetate, and a (1 : 1 mixture of 25-hydroperoxycycloart-23-en-3β-ol and 24-hydroperoxycycloart-25-en-3β-ol. These two cycloartane-type triterpenoids are mostly responsible for this cytotoxic activity. On the other hand, the antimicrobial potential of this plant was also evaluated against 36 microorganisms. The moderate antibacterial activity against 6 Staphylococcus aureus and 2 Dermabacter hominis strains is mainly attributed to the butanol partition whose major compounds are glycosides of flavones.

    The presence of fluoride in drinking water is known to reduce dental cavities among consumers, but an excessive intake of this anion might leads to dental and skeletal fluorosis. This study reports a complete survey of the fluoridated tap water taken from 100 water consumption points in Tunisia. The fluoride concentrations in tap water were between 0 and 2.4 mg L -1 . Risk assessment of Fluoride exposure was assessed depending on the age of consumers using a four-step method: hazard identification, toxicity reference values selection (TRVs), daily exposure assessment, and risk characterization. Our findings suggest that approximately 75% of the Tunisian population is at risk for dental decay, 25% have a potential dental fluorosis risk, and 20% might have a skeletal fluorosis risk according to the limits of fluoride in drinking water recommended by WHO. More investigations are recommended to assess the exposure risk of fluoride in other sources of drinking water such as bottled water. Copyright © 2017 Elsevier Ltd. All rights reserved.

  7. Reuse of reclaimed wastewater for golf course irrigation in Tunisia.

    2001-01-01

    In Tunisia, golf courses are irrigated with secondary treated effluent stored in landscape impoundments. The impact of the conveyance and storage steps on the physical-chemical and biological quality of irrigation water was evaluated on three golf courses over two years. It was found that the water quality varies all along the water route, from the wastewater treatment plant up to the irrigation site: nutrient and bacteria contents decreased along the route in the three cases. This variation depends on the wastewater quality, the length of the pipes conveying water, the number of regulation reservoirs and ponds, the water residence time in pipes, reservoirs and ponds, and the operation of the ponds. The bacteriological quality of irrigation water deteriorates during the irrigation period in the three golf courses as the ponds are operated as continuous flow reactors. The results obtained in this study indicate the inability of golf water supplies, as currently managed, to properly sanitize reclaimed wastewater and meet target quality criteria recommended by WHO (1989) for water intended for recreational use. For a safe reuse of reclaimed wastewater for golf course irrigation, changes in the design and operation of the ponds should be planned or additional treatment steps provided.

    Full Text Available In order to establish an updated checklist of terrestrial gastropod from Tunisia, a revision of the species of Sphincterochilidae is presented, using bibliographic and museum records and the results of our own field work. As a result, only two species, Sphincterochila candidissima and S. tunetana, are accepted to occur in Tunisia, and their type specimens are illustrated. The study of the morphological characters of the genital organs of both species clarified their subgeneric affiliation. Comparison of S. tunetana with S. cariosa from Lebanon showed that the first has to be classified within the subgenus Albea, and the latter within Sphincterochila s. str.; the subgenus Rima Pallary, 1910 remains in the synonymy of Sphincterochila s. str. Bibliographic records of S. baetica and S. otthiana from Tunisia could not be confirmed, the latter probably lives close to the border with Algeria.

  3. Choice of the exchange policies in the developments countries: Study of the competitiveness of Tunisia

    2008-01-01

    Full Text Available After the collapse of the Breton Woods system, the increased fluctuations of the exchange rates pushed the developing countries to adopt exchange rate policies to avoid rocking of the balance of payments. Since 1973, Tunisia adopted fixed or intermediary exchange rate policies to support or ameliorate her competitiveness and later to balance her current account. By calculating the real effective exchange rate misalignment, we showed that this country did not achieve her goals and that amelioration of competitiveness occurred only as from the moment when she softened her exchange policies. A policy of floating exchange rate is recommended for Tunisia specially why this country is more and more open. .

    The study area is located in the northeastern part of Tunisia about 60 km south of the Tunis city. It is bounded by the Gulf of Haematite in the East, Djebel Sidi Aberahmane in the West, The town of Nabeul in the south and the area of the town Kelibia in the north. The landscape is a coastal plain slightly sloping (3%) towards the sea. The groundwater of the Oriental coast aquifer system occurs mainly at two levels, a shallow aquifer up to depths of about 50 m whose reservoir is consisted by sediments of the Plio quaternary and a deep aquifer between about 150 and 400 m located in the sand stone formations of Miocene of the anticline of Djebel Sidi Abderrahmene. The climate of the region is semi-arid to sub-humid and of Mediterranean type. There are no perennial rivers in this region; but intense storms occasionally cause surface runoff, which is discharged by the oueds. The study is related to a technical cooperation project with the International Atomic Energy Agency, Vienna, Austria, aimed at the use of isotope techniques to study the seawater intrusion into the coastal aquifers of Cap Bon in Tunisia. In this regard, a better understanding of the recharge and flow regime as well as the origin or salinity of the groundwater was required. To reach this goal, isotope and geochemical investigations were carried out. Water samples were taken from wells, boreholes from deep and shallow aquifer of the Oriental coastal aquifer located between Beni Khiar in the south and Kelibia in the north. The samples were analysed for their chemical and isotopic compositions (18O, 2H, 3H, 13C, 14C, 34S). In the following, the results of these analyses are presented and discussed in terms of the recharge and flow regime of the groundwater and the origin and evolution of its salinity. The results of geochemical and isotopic studies have shown that the groundwater is very eterogeneous and suggest the aquifer is replenished by recent water coming from direct infiltration from rain.

    As urbanization increases in Tunisia, eating meals outside the home is becoming more frequent. Children are prime consumers for the fast food sold in the streets. Neither their nor their parents' attitude towards street food is well documented as yet. This study was conducted in the city of Bizerte in February 1998. Its aim was to gather information about street food and parents' and children's attitudes towards it to help organize educational sessions with the children, parents, teachers, and vendors. The study interviewed 421 primary school children, ranging in age from 6 to 15 years (mean age: 10 years), from 24 schools. Half received pocket money, a percentage that did not differ by sex. Three quarters of the children used more than 75% of their pocket money to buy street food. The items bought most frequently were candy (27.2%), sandwiches (23.9%), pastries (23.9%), sunflower seeds and peanuts (21%), and either pizza, chocolate, or cheese (20.3%); the largest proportion of money was spent on sandwiches. In more than half the cases (55.7% of the children), the main motivation for buying street food was either to replace or fill out a meal at home, with sandwiches or pastries. The parents' monthly income did not influence the children's purchasing behavior, but the rhythm of receiving pocket money did. Most children were satisfied with the nutritional and hygienic quality of the food available, but their opinion of this quality as well as the reasons for buying the food and the prices spent on it differed considerably from that of their parents. This study highlights the important role of street foods in the daily diet of schoolchildren and the need for appropriate nutrition education in primary schools.

    The species/genotypes of Echinococcus infecting a range of intermediate, canid and human hosts were examined as well as the intraspecific variation and population structure of Echinococcus granulosus sensu lato (s.l.) within these hosts. A total of 174 Echinococcus isolates from humans and ungulate intermediate hosts and adult tapeworms from dogs and jackals were used. Genomic DNA was used to amplify a fragment within a mitochondrial gene and a nuclear gene, coding for cytochrome c oxidase subunit 1 (cox1; 828 bp) and elongation factor 1-alpha (ef1a; 656 bp), respectively. E. granulosus sensu stricto was identified from all host species examined, E. canadensis (G6) in a camel and, for the first time, fertile cysts of E. granulosus (s.s.) and E. equinus in equids (donkeys) and E. granulosus (s.s.) from wild boars and goats. Considerable genetic variation was seen only for the cox1 sequences of E. granulosus (s.s.). The pairwise fixation index (Fst) for cox1 E. granulosus (s.s.) sequences from donkeys was high and was statistically significant compared with that of E. granulosus populations from other intermediate hosts. A single haplotype (EqTu01) was identified for the cox1 nucleotide sequences of E. equinus. The role of donkeys in the epidemiology of echinococcosis in Tunisia requires further investigation. © The Author 2014.

    There is wanting data regarding young ischemic stroke in developing countries, especially in Tunisia. The purpose of this study was to investigate risk factors and etiologies of young ischemic stroke in Tunisian and make a comparison with previous reports. A total of 102 young ischemic stroke patients (15-45 years old) were admitted, between January 1996 and August 2007, to 11 departments of internal medicine in different Tunisian hospitals. The risk factors for stroke were documented and assessed. Diagnosis workup consisted of anamnesis, complete physical examination and extensive laboratory, radiologic, immunologic, neurologic and cardiologic examination. Stroke etiologies were classified according the Trial of ORG 10172 in acute stroke treatment. There were 42 men (41.2%) and 60 women (58.89%) with a mean age at onset of 35.7 years. As regards stroke subtype, large-artery atherosclerosis was diagnosed in 6.9% of cases, cardioembolism in 11.8%, small-vessel occlusion in 8.8%, other determined etiology in 37.3% and undetermined etiology in 35.3%. Concerning the traditional risk factors, smoking (31.4%), hypertension and diabetes mellitus (12.7% for each one) and a family history of stroke (10.8%) were the most common. The mean follow-up period was 30.5 months. In our study, traditional risk factors were not-so-uncommon in young adults with ischemic stroke suggesting that prevention can go through controlling these factors. Stroke of other determined etiology was the most common among our patients, so that a broad and detailed diagnostic workup is crucial to puzzle out the etiology for more and better stroke prevention.

  8. Hydrocarbon potential of a new Jurassic play, central Tunisia

    International Nuclear Information System (INIS)

    Beall, A.O.; Law, C.W.

    1996-01-01

    A largely unrecognized Jurassic Sag Basin has been identified in central Tunisia, proximal to the Permo-Carboniferous flexure delineating the northern boundary of the Saharan platform of north Africa. The northwestern margin of the Sag is delineated by an extensive region of salt-cored anticlines and localized salt diapirs extending north and west. Due to lack of deep drilling, delineation of the Sag is largely based on regional gravity data. Subsidence of the Jurassic Sag Basin is characterized by rapid expansion of Jurassic sediments from 400 m. of tidal flat and shelf carbonate at the western outcrop to over 2000 meters of tidal flat and basinal carbonate and shale within the basin center, a five-fold expansion. Rapid loading of the basin continued into Lower Cretaceous time, marked by lateral flowage of Triassic salt into pronounced structural trends. Published source rock data and interpreted subsurface well data provided the basis for GENEX 1-D hydrocarbon generation and expulsion modeling of the Sag. Middle Jurassic black source shales typically contain Type II and Type III kerogens with T.O.C.'s ranging up to 4 percent. Modeling results indicate that middle Jurassic shales are presently mature for liquid generation within portions of the Sag, with maximum generation taking place during the Tertiary. Potential hydrocarbon generation yields, based on 60 meters of mature source shale, are 20,000 BOE/acre for gas and 75,000 BOE/acre for liquids. Prospects within the region could contain an estimated potential reserve of several T.C.F. or over 1 billion barrels of oil

    Full Text Available Tunisian geckos count nine species (1 is insular relict, 1 is endemic, 2 are ubiquitous and 5 are enfeoffed. We aim to determine factors influencing their distributions. Surveys were founded on environmental divisions. Presence/absence data for 113 grids were analyzed using multivariate tools. 18 environmental variables were revealed and clustered into five factors to model species distributions. Established models were further projected on non-explored areas within Tunisian territory. The distribution of continental geckos follows an indirect bidirectional gradient; the South-northward one is physiologically stressful and the North-southward one is biologically stressful. Five biogeographic regions were established showing concordance with climatic and vegetation regionalization. The distribution of non-anthropophilic species is positively correlated to thermal amplitudes gradient. The distribution of anthropophilic taxa is positively correlated to agricultural land-use. Oasis, sebkhas and chotts are particular landscapes that disturb both distributions. Predicted areas follow the yielded distribution patterns despite some discrepancy for S. sthenodactylus. The niche characterizing shows that land use and altitude increase the probability of occurrence of H. turcicus and T. mauritanica. Alternatively, they decrease the probability of the presence of T. deserti, T. neglecta, T. tripolitanus and S. petrii. Models could also show that the absence of S. sthenodactylus in northern regions is attributed to high altitudes and cereal land-use. As to T. fascicularis, the displacement of the northern limits of its range is mostly attributed to an improvement of field investigations. Established model of its distribution shows a restricted area of probable occurrence in central Tunisia confirming its endemism.

    1996-10-01

    War and AIDS-related mortality in Uganda have created an estimated 1.2 million orphans in the country. Child welfare advocates and nongovernmental organizations (NGOs) have therefore been working together for the past 4 years under an umbrella organization to coordinate efforts for vulnerable children. The Uganda Community-Based Association for Child Welfare (UCOBAC), links people and organizations involved in child advocacy, facilitates relations between the government and NGOs, and helps to strengthen the capacity of NGOs to identify and implement projects. UCOBAC emphasizes community-based initiatives which allow children to remain in their own communities instead of being institutionalized. One example of such an approach is a vocational skills training program in Rakai district established to help young orphans trying to make it on their own. More than 300 youths had benefitted from the program as of December 1994 and plans are underway to expand the program to 10 more districts. UCOBAC is also training communities and NGOs to identify and implement viable projects, and helps child welfare organizations by serving as a network for sharing information. UCOBAC came into existence in October 1990 with 93 members, including 57 local NGOs, 17 international NGOs, and 19 individual members. The organization has since established local offices in 35 of Uganda's 39 districts. UNICEF has thus far provided about US$130,000 for UCOBAC activities and will continue to fund local NGO initiatives through UCOBAC. UCOBAC, however, is giving priority to becoming financially independent of UNICEF within a couple of years. Future projects include an inventory of NGO child welfare projects, a child welfare resource library, and networking workshops with NGOs and government policymakers.

    Full Text Available In North Africa seasonal streams called wadi are an unique habitats with serve hydrological and thermal regime. Non-biting midges take an important part of freshwater biodiversity in North Africa. We present new data on the distribution and diversity of Chironomidae in North Tunisia. Larvae, pupal exuviae and adult males of chironomids were collected from a various freshwater ecosystems from May 2005 till April 2006. The aim of this study was to recognize the pattern of midge diversity in North Tunisia to estimate ecological value of running waters in the region. In total, 79 taxa were identified. Nearly all of the taxa were typical representatives of the Palaearctic and Mediterranean complexes. The majority of the investigated sites belonged to the protected areas in North Tunisia, such as the Ichkeul National Park, the Kroumerie Mountains and the El Feija National Park, part of the Intercontinental Reserve of the Mediterranean Biosphere. Altitudinal zonation of the communities composition was found in the lowland (250 m a.s.l. with maximum of 760 m. Whereas among the data 39 species are recorded from Tunisia for the first time, the species richness of Chironomidae is higher than previously estimated.

    Echinococcus granulosus sensu lato (s.l.) is a zoonotic disease highly endemic in Tunisia. Canids including stray and semi-stray dogs, jackals and foxes are known as definitive hosts and a wide range of ungulates have been shown to harbour the metacestode hydatid stage and may serve as intermediate hosts. Fertile hydatid cysts of Echinococcus equinus and E. granulosus sensu stricto (s.s.) were recently molecularly identified for the first time from Tunisian donkeys. E. granulosus (s.s.) was also identified from wild boars in Tunisia. Here we report the confirmation of hydatid cysts caused by E. granulosus (s.s.) in the critically endangered antelope, Addax nasomaculatus in Tunisia. DNA-based molecular analysis revealed that A.nasomaculatus was infected with E. granulosus (s.s.) which had a 100% identity with the main globally distributed E. granulosus (s.s.) (EgTu01) haplotype. Cysts of Taenia hydatigena (n=33) were also observed on the liver and in the body cavity. Due to their endangered status and their relatively small numbers, it is unlikely that hydatid infection of A. nasomaculatus will form a major contribution to the epidemiology and transmission of E. granulosus in Tunisia, but infection may result in pathology, morbidity and early mortality, and may still play a role in the perpetuation of the parasite in wildlife cycles.

    Although data on the parasite environmental contamination are crucial to implement strategies for control and treatment, information about zoonotic helminths is very limited in Tunisia. Contamination of areas with canid faeces harboring infective parasite elements represents a relevant health-risk impact for humans. The aim of this study was to assess the environmental contamination with eggs and oocysts of gastrointestinal parasites of dogs and wild canids in Tunisia with special attention to those that can be transmitted to humans. One thousand two hundred and seventy faecal samples from stray dogs and 104 from wild canids (red foxes and golden jackals) were collected from different geographical regions throughout Tunisia. The helminth eggs and protozoan oocysts were concentrated by sucrose flotation and identified by microscopic examination. The most frequently observed parasites in dog samples were Toxocara spp. (27.2%), E. granulosus (25.8%), and Coccidia (13.1%). For wild canid faeces, the most commonly encountered parasites were Toxocara spp. (16.3%) followed by Capillaria spp. (9.6%). The parasite contamination of dog faeces varied significantly from one region to another in function of the climate. To our knowledge, the study highlights for the first time in Tunisia a serious environmental contamination by numerous parasitic stages infective to humans. Efforts should be made to increase the awareness of the contamination risk of such parasites in the environment and implement a targeted educational program.

    To phenotypically, physiologically and molecularly characterize the causal agent of olive anthracnose in the northern Tunisia and to study its genetic variability and pathogenicity. A total of 43 isolates were obtained from symptomatic olives collected from four regions in northern Tunisia. A range of morphological and physiological characteristics was recorded; and a phylogenetic study, based on the sequence analysis of both internal transcribed spacers and TUB2 gene regions, was performed. Of the 43 isolates, 41 were identified as Colletotrichum acutatum s.s, and only two were affiliated to Colletotrichum gloeosporioides s.s. Two more representative Spanish isolates, included for comparison, were identified as Colletotrichum godetiae. Using six inter-simple-sequence-repeat markers, homogeneity between isolates from different locations and within the same species was recorded. In pathogenicity and virulence studies, C. gloeosporioides s.s was found to be less virulent, while the Spanish C. godetiae isolate was significantly more virulent than the Tunisian C. acutatum s.s. Olive anthracnose in the North of Tunisia is mainly caused by C. acutatum s.s species. This is the first study of olive anthracnose in Tunisia, which combines both phenotypic and molecular approaches. Colletotrichum acutatum s.s group was recorded for the first time in the country as the causal agent of olive anthracnose. © 2016 The Society for Applied Microbiology.

    Full Text Available Mulch effects on soil temperature, soil moisture content, soil chemical properties, growth and development, yield and yield components of late season cassava were investigated for three years on an acid ultisol in the tropical sa vanna zone of Southwestern Zaire. Diurnal soil temperature and soil moisture content were recorded at 30-day intervals during the first 4 months of growth. Cassava growth and development were monitored a t3, 6 and 9 months after planting while yield and yield components were noted at 12 months after planting. After each cropping year, changes in soil chemical constituents were recorded. Mulching significantly reduced soil temperature by about 3.5°C and increased soil moisture content by 6.1 % under late season cassava. Soil pH, soil organic carbon content, total nitrogen, soil available phosphorus and soil exchangeable cations (Ca, Mg, K increased as a result of increase in organic matter with continuous application of mulch for 3 years. Plant height, leaf area, shoot and root dry weights of cassava plants given mulch were significantly increased as compared to the plants in unmulched plots. Cassava plants given mulch produced more and bigger storage roots than unmulched plants. Storage root yield increased by 16.7, 28.1 and 57.7 % respectively in the first, the second and the third years of mulch application. The beneficiai effect of mulching over no-mulching increased from year to year, irrespective of cassava cultivars.

    The mobile laboratory provides a safe, rapid and flexible platform to provide effective diagnosis of Ebola virus as well as additional differential diagnostic agents in remote settings of equatorial Africa. During the 2007 Democratic Republic of Congo outbreak of Ebola-Zaire, the mobile laboratory was set up in two different locations by two separate teams within a day of equipment arriving in each location. The first location was in Mweka where our laboratory took over the diagnostic laboratory space of the local hospital, whereas the second location, approximately 50 km south near Kampungu at the epicentre of the outbreak, required local labour to fabricate a tent structure as a suitable pre-existing structure was not available. In both settings, the laboratory was able to quickly set up, providing accurate and efficient molecular diagnostics (within 3 h of receiving samples) for 67 individuals, including four cases of Ebola, seven cases of Shigella and 13 cases of malaria. This rapid turn-around time provides an important role in the support of patient management and epidemiological surveillance. © 2012 Blackwell Verlag GmbH.

    The recent and frequent drought events in the Middle East and Northern Africa (MENA) create an urgent need for scientists, stakeholders, and decision makers to improve the understanding of drought in order to mitigate its effects. It is well documented that drought is not caused by meteorological or hydrological conditions alone; social, economic, and political governance factors play a large part in whether the components in a water supply system are balanced. In the MENA region, for example, agricultural production can place a significant burden on water supply systems. Understanding the connection between drought and agricultural production is an important first step in developing a sound drought monitoring and mitigation system that links physical indicators with on-the-ground impacts. Drought affect crop yield, livestock health, and water resources availability, among others. A clear depiction of drought onset, duration and severity is essential to provide valuable information to adapt and mitigate drought impact. Therefore, it is important that to be able to connect and evaluate scientific drought data and informational products with societal impact data to more effectively initiate mitigation actions. This approach will further the development of drought maps that are tailored and responsive to immediate and specific societal needs for a region or country. Within the context of developing and evaluating drought impacts maps for the MENA region, this analysis investigates the use of different drought indices and indicators including the Standardized Precipitation Index (SPI), Normalized Difference Vegetation Index (NDVI) anomaly, land surface temperature (LST), and Evaporative Stress Index (ESI) for their ability to characterize historic drought events in Tunisia. Evaluation of a "drought map" product is conducted using data at the county level including crop yield, precipitation, in-country interviews with drought monitoring experts and agricultural

  6. The Radioisotopes production in tunisia, presentation of the CNSTN project

    2013-01-01

    Radio-isotopes required in medicine (nuclear medicine, neurology, cardiology, orthopedics) need a deep reflection and a scientific analysis of the problems related to the human health. The utilisation of radioisotopes in other fields such as chemistry, agriculture, industry, safety, earth sciences and environmental physics is also of great importance. In pharmaceutical companies, radioisotopes used in a laboratory of imaging for small animal to check the efficiency of drugs in vivo is touched upon in this presentation. Radioisotopes are also needed for different activities in platform dedicated to the training of radio pharmacist and radio biologist. The availability of radioisotopes in a research center such as the National Center of Nuclear Sciences and Technologies (NCNST) will improve the activity of existing skills and serve the country's development in the field of biomedical research. Tunisia has two projects of cyclotrons facilities: the first one is in the private sector and the second one is proposed by the NCNST. The realization of these projects requires a period of time estimated to two years for the feasibility study and two years more for constitution. In the meantime, it is necessary to establish a master's degree in radio-pharmacy / radio-biology to provide skills that may activate cyclotron facilities. One last test phase lasts 6 months to a year. The work within a cyclotron facility requires a rigorous and a lot of discipline (a little bit military) ordered by the risk of the isotope radioactive half-life and its radiation activity. Thus, it is necessary to provide to the staff, various training required for the functioning of the cyclotron. It is useful to insist on the importance of scientist's team which is going to put on the cyclotron and which consists of: radio-pharmacists, radio physicists experts in radiation protection, and engineer's operators of cyclotrons. It is useful to attract the attention that the specialties in the field of the

    Opsoclonus myoclonus syndrome (OMS) is a rare immune-mediated disorder characterized by opsoclonus, myoclonus, ataxia and behavioral changes. The aim of our study was to investigate the epidemiology, clinical features, etiological aspects and outcome of OMS in Tunisian children. We conducted a retrospective study over 11years (2005-2016) including all patients aged under 18years who were managed for newly diagnosed OMS in a tertiary care research centre for children with neurological symptoms. Epidemiological and clinical data were analyzed. Fifteen patients were included. The male-female ratio was 7:8. Median age of onset was 4.32years (range: 14months-16years). Time to diagnosis ranged between 2days and 10months. Median follow-up period was 3.8years (range: 2-6years). Acute ataxia was the preponderant inaugural feature. Mean severity score was 9 (range: 3-14). In "Tumor group" (n=7), the main underlying malignancy was neuroblastoma identified in 5 patient. In "No tumor group" (n=8), parainfectious and idiopathic OMS were identified in 5 and 3 patients, respectively. All patients received immunomodulatory treatment. Complete recovery of OMS symptoms was obtained in 12 children. Comparing the "Tumor group" and the "No tumor group", there were no differences in age of onset, sex ratio, main presenting symptom, median OMS severity score or responsiveness to treatment. However, sleep and behavioral disturbances were more frequent in the "No tumor group" (p=0.04). Neurological sequelae were equally found in both groups. Annual incidence of OMS in Tunisia could be estimated as 0.6 patients in children per million per year. Diagnosis may be challenging especially when the triad is incomplete. Although behavioral disturbances seem to be more frequent in the "No tumor group", our study suggests that there is no specific features differentiating paraneoplastic OMS from non paraneoplastic OMS. Acute symptoms are responsive to immunomodulatory treatment but long term follow

  8. Uganda: condoms provoke an AIDS storm.

    Science.gov (United States)

    Tebere, R

    1991-03-01

    An advertisement in the Uganda weekly Topic printed in 1990 is the center of the controversy over whether promoting condom use to prevent AIDS is really promoting immorality and promiscuity. The ad states: "The bible may save your soul but this condom will save you life." Critics have called the ad blasphemy for showing a condom package alongside the Bible; claimed the condom fools people into thinking they are safe from AIDS; and blamed the practice of supplying condoms for the moral decadence that is destroying the country. In contrast the national AIDS Control Program (ACP) believes that supplying university students, who may be the group at highest risk, with condoms, is wise because they at lest know how to use them properly. A spokesman for the ACP said that the condom is one of the limited options that exist to fight the life-threatening epidemic. Present Museven changed his views to November 1990 from a policy of encouraging abstinence and monogamy, to promoting condoms. This change in government policy coincided with the report of 17,422 cases of AIDS, and the estimate that 1.3 million people in Uganda are infected with HIV.

  17. Uganda's participation in CTBT activities and earthquake monitoring

    Tugume, F.A.

    2002-01-01

    Earthquake occurrence in Uganda is mostly related to East Africa Rift System. The country's western border lies within the Western branch of this system while the Eastern branch is only 200 km from its eastern border. The two tectonic features contribute to seismicity in Uganda. These are the Aswar shear zone running from Nimule at the border of Uganda and Sudan, to Mount Elgon on the Eastern border and Katonga fault break which cuts across the country from the foot hills of mount Rwenzori to the Western side of Lake Victoria. This unique tectonic setting makes Uganda one of most seismically active countries on the African continet as exemplified by some destructive earthquakes that have hit the country. For this reason the Government of uganda is in the process of setting up an earthquake monitoring system, the National Seismological Network, with efficient detectability, efficient data transmission and processing facilities so that earthquakes in Uganda can be properly assessed and seismic hazard studies of the country cunducted. The objectives of the said network, the seismic developments for the last two decades and its current satus are described

    2017-02-01

    Full Text Available Land use without adequate soil erosion control measures is continuously increasing the risk of soil erosion by water mainly in developing tropical countries. These countries are prone to environmental disturbance due to high population growth and high rainfall intensity. The aim of this study is to assess the state of soil erosion by water in Uganda at national and district levels, for various land cover and land use (LCLU types, in protected areas as well to predict the impact of support practices on soil loss reduction. Predictions obtained using the Revised Universal Soil Loss Equation (RUSLE model indicated that the mean rate of soil loss risk in Uganda’s erosion‐prone lands was 3.2 t∙ha−1∙y−1, resulting in a total annual soil loss of about 62 million tons in 2014. About 39% of the country’s erosion‐prone lands were comprised of unsustainable mean soil loss rates >1 t∙ha−1∙y−1. Out of 112 districts in Uganda, 66 districts were found to have unsustainable estimated soil loss rates >1 t∙ha−1∙y−1. Six districts in Uganda were found to have mean annual soil loss rates of >10 t∙ha−1∙y−1: Bududa (46.3 t∙ha−1∙y−1, Kasese (37.5 t∙ha−1∙y−1, Bundibugyo (28.9 t∙ha−1∙y−1, Bulambuli (20.9 t∙ha−1∙y−1, Sironko (14.6 t∙ha−1∙y−1 and Kotido (12.5 t∙ha−1∙y−1. Among the LCLU types, the highest soil loss rates of 11 t∙ha−1∙y−1 and 10.6 t∙ha−1∙y−1 were found in moderate natural forest and dense natural forest, respectively, mainly due to their locations in highland areas characterized by steep slopes ranging between 16% to 21% and their high rainfall intensity, ranging from 1255 mm∙y−1 to 1292 mm∙y−1. Only five protected areas in Uganda were found to have high mean estimated mean soil loss rates >10 t∙ha−1∙y−1: Rwenzori Mountains (142.94 t∙ha−1∙y−1, Mount Elgon (33.81 t∙ha−1∙y−1, Bokora corridor (12.13 t∙ha−1∙y−1

  1. Bribery in health care in Uganda.

    Hunt, Jennifer

    2010-09-01

    I examine the role of household permanent income in determining who bribes and how much they bribe in health care in Uganda. I find that rich patients are more likely than other patients to bribe in public health care: doubling household expenditure increases the bribery probability by 1.2 percentage points compared to a bribery rate of 17%. The income elasticity of the bribe amount is about 0.37. Bribes in the Ugandan public sector appear to be fees-for-service extorted from the richer patients amongst those exempted by government policy from paying the official fees. Bribes in the private sector appear to be flat-rate fees paid by patients who do not pay official fees. I do not find evidence that the public health care sector is able to price discriminate less effectively than public institutions with less competition from the private sector.

    A 64-year old traditional birth attendant (TBA), Zowe Namasiga, in Kyobe county in the Rakai district of Uganda, delivered her 1st baby when she was 12 years old. She learned how to deliver babies by watching her father deliver babies. She married at 14 and had 7 children of her own. She delivered 2 of her own children all alone. She attended a 1-week workshop for TBAs hosted by World Vision International and attended by 52 other TBAs. The medical services that exist in rural Uganda and tend to be of low quality. The leading problem for pregnant women in Rakai district in insufficient transport. The closest clinic is 8 miles away from where the workshop was held, but it has no midwives and the staff are not trained to deliver babies. The ratio of midwife to women of reproductive age in Rakai district is 1:5000. Ms. Namasiga has to refer high risk patients to Kitovu Hospital, a distance of 62 km. In the workshop, illustrations of male and female reproductive systems helped them learn that the uterus is not connected to the digestive system. The TBAs learned about the importance of hygiene and of encouraging women to seek prenatal care and to receive tetanus toxoid injections. The workshop taught them how to identify high risk women and to refer them to the hospital. Few women go to the hospital, though, because town midwives do not treat them kindly. One participant described how she keeps premature babies alive: wraps them and places them in a circle of 5-liter metal cans filled with warm water. TBAs are concerned about AIDS. In fact, the last grandchild Ms. Namasiga delivered was born to parents with AIDS. She delivers babies with her bare hands, but now asks for payment so she can buy gloves to protect her cracked hands. Most TBAs care for AIDS orphans. TBAs assist at 90% of deliveries in this rural district.

  3. The geothermal gradient map of Central Tunisia: Comparison with structural, gravimetric and petroleum data

    1987-10-01

    Five hundred and fifty temperature values, initially measured as either bottom-hole temperatures (BHT) or drill-stem tests (DST), from 98 selected petroleum exploration wells form the basis of a geothermal gradient map of central Tunisia. A "global-statistical" method was employed to correct the BHT measurements, using the DST as references. The geothermal gradient ranges from 23° to 49°C/km. Comparison of the geothermal gradient with structural, gravimetric and petroleum data indicates that: (1) the general trend of the geothermal gradient curves reflects the main structural directions of the region, (2) zones of low and high geothermal gradient are correlated with zones of negative and positive Bouguer anomalies and (3) the five most important oil fields of central Tunisia are located near the geothermal gradient curve of 40° C/km. Such associations could have practical importance in petroleum exploration, but their significance must first be established through further investigation and additional data.

    Full Text Available Epidemiological investigations on Fasciola hepatica fasciolasis were carried out from July 2004 to June 2005 in the Gafsa oases (Tunisia after the detection of a human case. Three habitats were studied: one in El Gsar and two in Ain Soltan. The prevalence of human infection was 6.6 %. The presence of the parasite was detected through serology in 14.3 % of cattle, 35 % of sheep and 68.4 % of goats. The plants Apium nodiflorum, Oxalis cernua and Sonchus maritimus were suspected to be at the origin of animal contamination and Apium nodiflorum was incriminated in human infection. The prevalence of the infection of the intermediate host Galba truncatula (G. truncatula was 19.2 % from July 2004 to June 2005. Gafsa oases constitute a new location for the development of fasciolasis in the southern west of Tunisia.

  5. International financial institutions and health in Egypt and Tunisia: change or continuity?

    Science.gov (United States)

    Ismail, Sharif

    2013-01-01

    The revolutions in Egypt and Tunisia appeared to herald a re-casting of International Monetary Fund and World Bank policy across the region. Public pronouncements by the heads of both institutions in the months following February 2011 acknowledged flaws in their approach to macroeconomic advice, against a background of worsening socioeconomic indicators, widespread youth unemployment, and widening health inequalities. Evidence on the ground, however, suggests continuity rather than change in international financial institution policies in Egypt and Tunisia, notwithstanding the emergence of a powerful new player-the European Bank for Reconstruction and Development. In the long term, new electoral realities and hardening public opposition in both countries seem likely to force a fundamentally different relationship between regional governments and the major international financial institutions than existed before 2011.

    2016-01-01

    Full Text Available This paper analyzes the evolution of food and nutrition security in Tunisia, judges its sustainability within water scarcity conditions and free trade areas, with a specific focus on the meat sector. For such purpose, the FAO indicators and Food Balance Sheets, as well as the Global Food Security Index are all analyzed. Virtual water, owed to meat and cereals for animal feed production and trade, was estimated to expect food security sustainability. Results indicated that Tunisian food and nutrition security (FNS has been improved over the years, but its stability remains vulnerable because of the political and economic risks and the dependence of Tunisia on imported cereals for animal feed due to water scarcity. Tunisian agricultural policy, especially in both sectors of cereals and meat, should be readjusted to guarantee food and nutrition sustainability.

    2013-12-01

    Full Text Available The main objective of this study was to highlight the fertilizing capacity of the extract of ovine compost (prepared to the simple infusion in gardening nursery, while specifying the appropriate ratios of extraction and dilution ,for soilless plant fertigation intended for two strategic summer crops in Tunisia: seasonal tomato and seasonal pepper. It is clear that such extraction ratio of 1: 5 is effective for plants fertigation of two considered species. In addition, it has been shown that 200 times dilution of the concentrated extract is beneficial for the growth of tomato plants. However, this organic liquid fertilizer with different dilutions applied and in the experimental conditions adopted, wasn’t moderately efficient in stimulating the growth of pepper plants. The importance of this type of compost produced from sheep biomass, widely available in Tunisia, encourage the diversification of its exploitation, which is the object of this preliminary work, deserving more future investigations.

    2011-12-01

    Full Text Available The aim of this paper is to describe and interpret suiform teeth from Moroto, Uganda, and Ngorora, Kenya, which contribute to the debate about hippo-anthracothere-whale relationships. The early stages of hippopotamid evolution are relatively poorly known on account of the paucity of their fossil record older than 7 Ma. New specimens of Morotochoerus from Uganda reveal that it is not closely related to Hippopotamidae; the superficial resemblances of the cheek teeth to those of hippos represent convergences and not homologies. Restricted samples of Palaeopotamus ternani are available from the Middle Miocene of Kenya {Maboko, ca 16 Ma; Muruyur, ca 14.5 Ma; Fort Ternan, ca 13.7 Ma} while from the base of the late Miocene, Kenyapotamus coryndonae is known from Kenya {Ngerngerwa, ca 10.5-10 Ma; Nakali, ca 10.5 Ma; Samburu Hills, ca 9.5 Ma}, Ethiopia {Ch’orora, ca 10.5 Ma} and Tunisia {Beglia Formation ca 11-10 Ma}. The recovery of specimens of Kenyapotamus from the Ngorora Formation, Kenya, aged ca 11 Ma, is of interest because it includes well preserved teeth, including an m/3 in good condition. These specimens support the hypothesis that hippopotamids descended from palaeochoerids and not from anthracotheres.El objetivo de este trabajo es describir e interpretar los dientes suiformes de Moroto, Uganda, y Ngorora, Kenia, que contribuyen al debate sobre las relaciones hipo-anthracothere-whale.

    Three tetrapod track assemblages from the early-middle Mesozoic of southern Tunisia are reported. The strata exposed at the Tejra 2 clay-pit near the Medenine and Rehach site, located in the vicinity of Kirchaou, contain the first tetrapod tracks found in the Triassic of Tunisia. The Middle Jurassic (early Aalenian) dinosaur tracks are reported from the Mestaoua plain near Tataouine. In the Middle Triassic outcrop of the Tejra 2 clay-pit, tridactyl tracks of small and medium-sized dinosauromorphs, were discovered. These tracks represent the oldest evidence of dinosaur-lineage elements in the Triassic deposits of Tunisia. Similar tracks have been described from the Middle Triassic of Argentina, France and Morocco. An isolated set of the manus and pes of a quadrupedal tetrapod discovered in Late Triassic Rehach tracksite is referred to a therapsid tracemaker. The Middle Jurassic deposits of the Mestaoua plain reveal small and large tridactyl theropod dinosaur tracks (Theropoda track indet. A-C). Based on comparison with the abundant record of Triassic tetrapod ichnofossils from Europe and North America, the ichnofauna described here indicates the presence of a therapsid-dinosauromorph ichnoassociation (without typical Chirotheriidae tracks) in the Middle and Late Triassic, which sheds light on the dispersal of the Middle-Upper Triassic tetrapod ichnofaunas in this part of Gondwana. The reported Middle Jurassic ichnofauna show close similarities to dinosaur track assemblages from the Lower and Middle Jurassic of northwestern Africa, North America, Europe and also southeastern Asia. Sedimentological and lithostratigraphic data of each new tracksite have been defined on published data and new observations. Taken together, these discoveries present a tantalizing window into the evolutionary history of tetrapods from the Triassic and Jurassic of southern Tunisia. Given the limited early Mesozoic tetrapod record from the region, these discoveries are of both temporal and

    This paper examines the impact of natural gas consumption, real gross fixed capital formation and trade on the real GDP in the case of Tunisia over the period 1980–2010. We use an Autoregressive Distributed Lag (ARDL) bounds testing approach to test for cointegration between the variables. The Toda–Yamamoto approach is then used to test for causality. Our findings indicate the existence of a long-term relationship between the variables. Natural gas consumption, real gross fixed capital formation and trade add in economic growth. Natural gas consumption, real gross fixed capital formation and real trade cause real GDP in Tunisia. These findings open up new insights for policymakers to formulate a comprehensive energy policy to sustain economic growth in the long-term. - Highlights: • We study how gas consumption, fixed capital formation and trade affect GDP in Tunisia. • We use auto-regressive distributed lag bounds testing approach and causality tests. • Gas consumption, real gross fixed capital formation and trade add in economic growth

    2002-01-01

    The signature of humid climatic episodes in the Holocene paleoclimatic history of Tunisia are evident in outcroppings along riverbanks almost all over the Tunisian drainage network. Previous multidisciplinary studies have already identified some sites where these remnants can contribute valuable information for reconstruction of paleoenvironmental and paleoclimatic variations in the presently hyper-arid zone of the Northern Sahara. Sedimentary deposits outcropping on Wadi Leben and Wadi Ben Sellam banks, in the Maknassy Basin (Central Tunisia), have been sampled. Multidisciplinary studies, including prehistory, sedimentology, mineralogy, ecology and radiochronology have been conducted to improve palaeoenvironmental interpretations and to determine a precise chronological history of humid episodes during the Holocene in Tunisia. This paper deals with the interpretation of results obtained from the Maknassy Basin in comparison with some other Tunisian sites in order to highlight Holocene humid episodes. Establishment of a precise chronological framework is prerequisite to exploring potential relationships between the occurrence of humid phases and recharge of aquifers located in this area. (author)

    Dieback and wilting symptoms caused by complex soilborne fungi are nowadays the most serious threatening disease affecting olive trees (Olea europaea) in Tunisia and presumably in many Mediterranean basin countries. Fusarium is one of the important phytopathogenic genera associated with dieback symptoms of olive trees. The objective of the present study was to confirm the pathogenicity of Fusarium spp. isolated from several olive-growing areas in Tunisia. According to the pathogenic test done on young olive trees (cv. Chemlali), 23 out of 104 isolates of Fusarium spp. were found to be pathogenic and the others were weakly or not pathogenic. The pathogenic Fusarium spp. isolates were characterized using molecular methods based on ITS PCR. Isolation results revealed the predominance of Fusarium solani (56.5%) and F. oxysporum species (21.7%) compared to F. chalmydosporum (8.7%), F. brachygibbosum (8.7%) and F. acuminatum (4.34%). Based on pathogenicity test, disease severity was highly variable among the 23 pathogenic isolates tested (P Fusarium spp. might be a major agent causing dieback disease of olive trees in Tunisia.

    Highlights: • Evaluate the geothermal energy in Tunisia. • Study of the performance of GSHP system for cooling space. • GSHP is a promising alternative for building cooling in Tunisia. - Abstract: The main purpose of this paper is to study the energetic potential of the deployment in Tunisia of the Ground Source Heat Pump (GSHP) system for cooling mode application. Therefore, a pilot GSHP system using horizontal Ground Heat Exchanger (GHE) was installed and experimented in the Research and Technology Center of Energy (CRTEn), Borj Cédria. The experiment is conducted in a test room with a floor area of about 12 m 2 . In the floor of the tested room is integrated a polyethylene exchanger (PEX) used as a radiant floor cooling (RFC) system. The experimental setup mainly includes the ground temperature, the temperature and flow rate of water circulating in the heat pump and the GHE, as well as the power consumption of the heat pump and circulating pumps. These experimental data are essentially used to evaluate the coefficient of performance of the heat pump (COP hp ) and the overall system (COP sys ) for continuous operation mode. The COP hp and the COP sys were found to be 4.25 and 2.88, respectively. These results reveal that the use of the ground source heat pump is very appropriate for Tunisian building cooling

    Utica was a flourishing port city in northern Tunisia since the Phoenician times, 12-9th century B.C., until the 4th century A.D.. However, at present it is located 10 km from the coastline after very fast late Holocene progradation of the Mejerda River delta into the bay of Utica. This fast delta progradation occurred after Mejerda River captured Tine River increasing 140 % the river catchment area. Charcoal fragments present in the youngest Tine river terrace at the wind gap give a conventional radiocarbon age of 3240 +/- 30yr BP, indicating that the capture occurred after this date. Quaternary fluvial terraces located in the Tine River paleovalley have been folded and uplifted above a fold related to the active El Alia Tebousouk reverse fault (ETF). Continued uplift of the Tine River valley above the ETF favoured headward erosion of the Medjerda river tributaries creating a transverse drainage that captured Tine River. This capture produced an important change in sediment discharge along the northern Tunisia coast driving sediments to the Gulf of Tunis instead of feeding the Tyrrhenian Sea through the Ichkeul and Bizerte lakes. Although anthropogenic derived degradation of northern Tunisia land for agricultural purposes probably influenced the increase in sediment into the Utica bay, the main cause of rapid progradation of the Medjerda River delta during the late Holocene is related to its increase in drainage area after capturing the Tine River. This process was mostly driven by local contractive tectonics linked to the seismogenic Alia Tebousouk reverse fault.

    In Tunisia, potato virus Y (PVY) currently presents a significant threat to potato production, reducing tuber yield and quality. Three hundred and eighty-five potato samples (six different cultivars) collected in autumn 2007 from nine regions in Tunisia were tested for PVY infection by DAS-ELISA. The virus was detected in all regions surveyed, with an average incidence of 80.26%. Subsequently, a panel of 82 Tunisian PVY isolates (PVY-TN) was subjected to systematic biological, serological and molecular typing using immunocapture reverse-transcription polymerase chain reaction and a series of PVY OC - and PVY N -specific monoclonal antibodies. Combined analyses revealed ~67% of PVY NTN variants of which 17 were sequenced in the 5'NTR-P1 region to assess the genetic diversity and phylogenetic relationship of PVY-TN against other worldwide PVY isolates. To investigate whether selective constraints could act on viral genomic RNA, synonymous and non-synonymous substitution rates and their ratio were analyzed. Averages of all pairwise comparisons obtained in the 5'NTR-P1 region allowed more synonymous changes, suggesting selective constraint acting in this region. Selective neutrality test was significantly negative, suggesting a rapid expansion of PVY isolates. Pairwise mismatch distribution gave a bimodal pattern and pointed to an eventually early evolution characterizing these sequences. Genetic haplotype network topology provided evidence of the existence of a distinct geographical structure. This is the first report of such genetic analyses conducted on PVY isolates from Tunisia.

    In recent years, North African (NA) countries ceased to be emigration-only countries and are now on the verge of becoming immigration as well as transit countries for economic migrants and refugees. Contextual as well as structural long-term factors are driving these changes. The ongoing crises in Africa and the Middle East are prompting strong outflows of refugees, which are likely to induce NA countries to share some common public policy and public health concerns with European countries in a near future. This article highlights some aspects of these changes, from the study of the consequences of the 2011 Libyan crisis in Tunisia. It addresses individual trajectories and health concerns of refugees in and out North Africa from a study of the Choucha camp in Tunisia. The camp opened to immigrants from Libya during the 2011 crisis and accommodated the bulk of the refugees flow to Tunisia until July 2012. The study includes a monographic approach and a qualitative survey in the Choucha camp refugees. We describe the crisis history and the health response with a focus on the camp. We then address refugees' trajectories, and health needs and concerns from the interviews we collected in the camp in April 2012. © The Author 2014.

Safa Fathallah*, Rim Ben Amor and Moncef Gueddari Unit of Research of Geochemistry and Environmental Geology. Faculty of Science of Tunis, University of Tunis El Manar, 2092. (*) Corresponding author: safa_fathallah@yahoo.fr The coast of Sousse-Monastir in eastern of Tunisia, has undergone great changes, due to natural and anthropic factors. Increasing human use, the construction of two ports and coastal urbanization (hotels and industries) has accelerated the erosion process. The coastal defense structures (breakwaters and enrockment), built to protect the most eroded zone are efficient, but eroded zones appeared in the southern part of breakwaters. Recent and historic aerial photography was used to estimate, observe, and analyze past shoreline and bathymetric positions and trends involving shore evolution for Sousse-Monastir coast. All of the photographs were calibrated and mosaicked by Arc Map Gis 9.1, the years used are 1925, 1962, 1988, 1996, and 2001 for shoreline change analysis and 1884 and 2001 for bathymetric changes. The analyze of this photographs show that the zone located at the south of breakwater are mostly eroded with high speed process (2m/year). Another zone appears as eroded at the south part of Hamdoun River, with 1,5m/year erosion speed . Keywords: Shoreline evolution, defense structures, Sousse-Monastir coast, Tunisia.

    This paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country, Tunisia, during the period 1961-2004. The investigation is made on the basis of the environmental Kuznets curve hypothesis, using time series data and cointegration analysis. Carbon dioxide (CO{sub 2}) and sulfur dioxide (SO{sub 2}) are used as the environmental indicators, and GDP as the economic indicator. Our results show that there is a long-run cointegrating relationship between the per capita emissions of two pollutants and the per capita GDP. An inverted U relationship between SO{sub 2} emissions and GDP has been found, with income turning point approximately equals to 1200 (constant 2000 prices) or to 3700 (in PPP, constant 2000 prices). However, a monotonically increasing relationship with GDP is found more appropriate for CO{sub 2} emissions. Furthermore, the causality results show that the relationship between income and pollution in Tunisia is one of unidirectional causality with income causing environmental changes and not vice versa, both in the short-run and long-run. This implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth. It could be a feasible policy tool for Tunisia to achieve its sustainable growth in the long-run. (author)

    Full Text Available Effective utilization of quality business information is crucial in attaining long-term and sustainable economic growth of the Small and Medium Enterprises (SMEs. It is established that SMEs in northern Uganda operate in a business environment that is characterized by fragmented and incomplete information. It is a situation where an awareness of markets, technology, policies, regulations and finance is limited because businesses fail to receive timely business information. This article reports a portion of the results of a larger study using a descriptive design with survey research and other techniques. The study examined the problems SMEs in northern Uganda face in accessing business information; identified problems information providers face in providing business information to the SMEs in the region and attempted to establish whether SMEs in northern Uganda use public libraries in accessing business information as should be expected. The study’s respondents included the SMEs, information providers and business policy makers with the response rate of 87.3%; 72% and 85% respectively. The article proposes strategic interventions for business information to be accessed by the SMEs. It concludes that there is a need for Uganda and, in particular, northern Uganda to develop a strategy for business information access by the SMEs

    Full Text Available Climate projections in Sub-Saharan Africa (SSA forecast an increase in the intensity and frequency of droughts with implications for maize production. While studies have examined how maize might be affected at the continental level, there have been few national or sub-national studies of vulnerability. We develop a vulnerability index that combines sensitivity, exposure and adaptive capacity and that integrates agroecological, climatic and socio-economic variables to evaluate the national and spatial pattern of maize yield vulnerability to droughts in Uganda. The results show that maize yields in the north of Uganda are more vulnerable to droughts than in the south and nationally. Adaptive capacity is higher in the south of the country than in the north. Maize yields also record higher levels of sensitivity and exposure in the north of Uganda than in the south. Latitudinally, it is observed that maize yields in Uganda tend to record higher levels of vulnerability, exposure and sensitivity towards higher latitudes, while in contrast, the adaptive capacity of maize yields is higher towards the lower latitudes. In addition to lower precipitation levels in the north of the country, these observations can also be explained by poor soil quality in most of the north and socio-economic proxies, such as, higher poverty and lower literacy rates in the north of Uganda.

    2016-08-01

    Full Text Available The present article aims to evaluate the role of different macroeconomic variables that may promote the entry of the foreign direct investment (FDI in the industrial sector in Tunisia. In recent decades, several researches indicate that despite the significant impact of the FDI as an important catalyst of development, its benefits remain unequally distributed between countries, sectors and communities. For this reason, the competition between countries becomes more intense and depends on a large set of factors having different importance. In the same order of ideas, we try to estimate the impact of these factors on the FDI attractiveness in Tunisia through an econometric modelling with panel data over the period 2000-2014. We found that the traditional economic factors have the greatest and more significant impact. Also, the results imply that the multinational companies adopt essentially the vertical implementation strategy to invest in Tunisia. The findings have a great value for the decision-makers in Tunisia who can concentrate their efforts on the most important variables to develop the competitiveness of Tunisia.

    Malaria due to P. falciparum is the number one cause of morbidity and mortality in Uganda where it is highly endemic in 95% of the country. The use of efficacious and effective antimalarial medicines is one of the key strategies for malaria control. Until 2000, Chloroquine (CQ) was the first-line drug for treatment of uncomplicated malaria in Uganda. Due to progressive resistance to CQ and to a combination of CQ with Sulfadoxine-Pyrimethamine, Uganda in 2004 adopted the use of ACTs as first-line drug for treating uncomplicated malaria. A review of the drug policy change process and postimplementation reports highlight the importance of managing the policy change process, generating evidence for policy decisions and availability of adequate and predictable funding for effective policy roll-out. These and other lessons learnt can be used to guide countries that are considering anti-malarial drug change in future.

    Rotavirus vaccines have the potential to prevent a substantial amount of life-threatening gastroenteritis in young African children. This paper presents the results of prospective cost-effectiveness analyses for rotavirus vaccine introduction for Kenya and Uganda. In each country, a national consultant worked with a national technical working group to identify appropriate data and validate study results. Secondary data on demographics, disease burden, health utilization, and costs were used to populate the TRIVAC cost-effectiveness model. The baseline analysis assumed an initial vaccine price of $0.20 per dose, corresponding to Gavi, the Vaccine Alliance stipulated copay for low-income countries. The incremental cost-effectiveness of a 2-dose rotavirus vaccination schedule was evaluated for 20 successive birth cohorts from the government perspective in both countries, and from the societal perspective in Uganda. Between 2014 and 2033, rotavirus vaccination can avert approximately 60,935 and 216,454 undiscounted deaths and hospital admissions respectively in children under 5 years in Kenya. In Uganda, the respective number of undiscounted deaths and hospital admission averted is 70,236 and 329,779 between 2016 and 2035. Over the 20-year period, the discounted vaccine program costs are around US$ 80 million in Kenya and US$ 60 million in Uganda. Discounted government health service costs avoided are US$ 30 million in Kenya and US$ 10 million in Uganda (or US$ 18 million including household costs). The cost per disability-adjusted life-year (DALY) averted from a government perspective is US$ 38 in Kenya and US$ 34 in Uganda (US$ 29 from a societal perspective). Rotavirus vaccine introduction is highly cost-effective in both countries in a range of plausible 'what-if' scenarios. The involvement of national experts improves the quality of data used, is likely to increase acceptability of the results in decision-making, and can contribute to strengthened national

    Finger millet (Eleusine coracana) is a subsistence crop grown in Sub-Saharan Africa and the Indian Sub-continent. Fusarium species occurring on this crop have not been reported. Approximately 13% of the Fusarium isolates recovered from finger millet growing at three different locations in eastern Uganda belong to Fusarium verticillioides, and could produce up to 18,600 µg/g of total fumonisins when cultured under laboratory conditions. These strains are all genetically unique, based on AFLP analyses, and form fertile perithecia when crossed with the standard mating type tester strains for this species. All but one of the strains is female-fertile and mating-type segregates 13:20 Mat-1:Mat-2. Three new sequences of the gene encoding translation elongation factor 1-α were found within the population. These results indicate a potential health risk for infants who consume finger millet gruel as a weaning food, and are consistent with the hypothesis that F. verticillioides originated in Africa and not in the Americas, despite its widespread association with maize grown almost anywhere worldwide.

    A total of 118 sera were collected during 2016 from two groups of dromedaries from Kebili and Medenine governorates in the south of Tunisia. The aim of this study was to provide the first serological investigation of four emerging vector-borne diseases in two groups of dromedaries in Tunisia. Sera were tested by ELISA and serum neutralisation test to identify West Nile virus (WNV), bluetongue virus (BTV), epizootic haemorrhagic disease virus (EHDV) and Rift Valley fever virus (RVFV). In the first group, the seroprevalence for BTV was 4.6%, while in the second group, it was 25.8% for WNV and 9.7% for BTV. Only serotype 1 was detected for BTV in the two groups. No evidence for circulation of RVF and EHD viruses was revealed. Results indicated that dromedaries can be infected with BTV and WNV, suggesting that this species might play a significant role in the epizootiology of these viral diseases in Tunisia and neighbouring countries.

    Recent work has proposed the delamination of the subcontinental mantle lithosphere under northern Tunisia during the late Miocene. This process is required to explain the present location of the Tunisian segment of the African slab, imaged by seismic tomography, hanging under the Gulf of Gabes to the south of Tunisia. Thus, having retreated towards the SE several hundred km from its original position under the Tellian-Atlas nappe contact that crops out along the north of Tunisia. However, no tectonic structures have been described which could be related to this mechanism of lithospheric mantle peeling. Here we describe for the first time extensional fault systems in northern Tunisia that strongly thinned the Tellian nappes, exhuming rocks from the Tunisian Atlas in the core of folded extensional detachments. Two normal fault systems with sub-orthogonal extensional transport occur. These were active during the late Miocene associated to the extrusion of 13 Ma granodiorite and 9 Ma rhyodacite in the footwall of the Nefza detachment. We have differentiated an extensional system formed by low-angle normal faults with NE- and SW-directed transport cutting through the Early to Middle Miocene Tellian nappen stack and a later system of low and high-angle normal faults that cuts down into the underlying Tunisian Atlas units with SE-directed transport, which root in the Nefza detachment. Both normal fault systems have been later folded and cut by thrusts during Plio-Quaternary NW-SE directed compression. These findings change the interpretation of the tectonic evolution of Tunisia that has always been framed in a transpressive to compressive setting, manifesting the extensional effects of Late Miocene lithospheric mantle delamination under northern Tunisia.

We detected Rickettsia felis in fleas, Rickettsia massiliae Bar 29 and the Rickettsia conorii Israeli spotted fever strain in ticks, and Rickettsia conorii subsp. conorii and Rickettsia spp. in both arthropods. The sensitivity of the adopted technique allowed the identification of a new association between fleas and R. conorii subsp. conorii species. The presence of these vector-borne Rickettsia infections should be considered when diagnosing this disease in humans in Tunisia. PMID:24226919

    Scorpion envenomation is still a frequent occurance in tropical and subtropical regions. In Tunisia, multiple studies on scorpion envenoming have contributed to an improved understanding of cardiac dysfunction and factors predictive of poor prognosis. These previous studies have contributed to the current standardized management of envenomed patients. However, the epidemiology of scorpion envenoming in Tunisia has not been updated for more than 10 years. The aim of this study was to report an update of the epidemiological features of scorpion envenomation in the southern region of Tunisia. This is a retrospective monocentric study including all patients admitted in the emergency room for scorpion envenomation. Cases were collected from emergency medical files during a 3-year period (2013-2015). The diagnosis of scorpion envenomation was made by history of a scorpion sting. All files in which scorpion envenomation was not certain were excluded. Data are presented as mean±SD with range or percentages, as appropriate. We enrolled 282 patients aged 27.4±22.8 years with a 1:1 sex ratio. During surveillance in the emergency room, 39 patients developed cardiac dysfunction. Overall, 42 patients (14.9%) were at stage 3 of severity, and 240 patients (85.1%) had moderate scorpion envenomation (stage 2). Only 1 patient died a few hours after admission. In the remaining cases, the outcome was good. Our results show the improvement in mortality rates even in severe presentations. This study found that the outcome of scorpion-stung patients has clearly improved. This enhancement can be explained by early medical consultation and standardized management of patients with predictive factors for cardiac dysfunction. Copyright © 2017 Wilderness Medical Society.

    Breast cancer remains a worldwide public health problem. In Tunisia, it is considered to be the primary women's cancer and causes high morbidity and mortality. This study aimed to investigate female knowledge, attitudes and practice of breast cancer screening in the region of Monastir (Tunisia). We conducted a descriptive cross-sectional design exploring knowledge, attitudes and practices of women in the region of Monastir on breast cancer screening. The study was conducted in health centres of this region from 1 March 2009 to 30 June 2009. Data were collected via a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods and attitudes towards the relevance and effectiveness of breast cancer screening. A scoring scheme was used to score women's responses. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 92% of participants had poor knowledge of the specific risk factors for breast cancer and 63.2% had poor knowledge of the screening methods. Proper practice of breast cancer screening was observed in 14.3% of cases. Multiple logistic regression analysis showed that good knowledge of risk factors and screening methods, higher level of education and positive family history of breast cancer were independently correlated with breast cancer screening practice. This study revealed poor knowledge of breast cancer and the screening methods as well as low levels of practice of breast cancer screening among women in the region of Monastir. Results justify educational programs to raise women's adherence to breast cancer screening programs in Tunisia.

    The aim of our study was to examine epidemiological aspects of child abuse and neglect in Tunisia. We conducted a retrospective and descriptive study over a period of 10 years (January 2006-December 2015), based on the files handled by the Child Protective Services (CPS) agency in the city of Sousse, Tunisia. During the study period, 3736 referrals were received by the CPS agency of Sousse. Of the total, 2212 (59.2%) were screened in and investigated. Of the investigated cases, 317 (14,3%) were substantiated as abuse or neglect. The reports of maltreatment came mostly from parents (37.8%). Neglect was the major type of maltreatment (51.4%) and an association of 2 types of maltreatment was found in 76 cases (24%). Parents were the perpetrators in 221 cases (69.7%). The average age of the victims was 10 years and boys accounted for 56%. In the 257 cases where the marital status of the parents was noted in the files, the parents were divorced in 62 cases (24.1%) and the child lived with a single mother in 35 cases (13.6%). Alcohol addiction was found in 21 parents (6.6%) and one of the parents was incarcerated in 39 cases (12.3%). As for the socio-economic status, it was evaluated in 188 families and was low in 123 cases (65.4%). In the absence of studies related to this scourge in Tunisia, we hope to raise awareness of the abuse and alert those who come into contact with the child on the importance of detecting and reporting early maltreatment and thus to introduce more appropriate care. A comprehensive prevention strategy needs to be established by addressing risk factors, cultural norms conducive to abuse and unwanted pregnancies.

    An outbreak of Ebola disease was reported from Gulu district, Uganda, on 8 October 2000. The outbreak was characterized by fever and haemorrhagic manifestations, and affected health workers and the general population of Rwot-Obillo, a village 14 km north of Gulu town. Later, the outbreak spread to other parts of the country including Mbarara and Masindi districts. Response measures included surveillance, community mobilization, case and logistics management. Three coordination committees were formed: National Task Force (NTF), a District Task Force (DTF) and an Interministerial Task Force (IMTF). The NTF and DTF were responsible for coordination and follow-up of implementation of activities at the national and district levels, respectively, while the IMTF provided political direction and handled sensitive issues related to stigma, trade, tourism and international relations. The international response was coordinated by the World Health Organization (WHO) under the umbrella organization of the Global Outbreak and Alert Response Network. A WHO/CDC case definition for Ebola was adapted and used to capture four categories of cases, namely, the 'alert', 'suspected', 'probable' and 'confirmed cases'. Guidelines for identification and management of cases were developed and disseminated to all persons responsible for surveillance, case management, contact tracing and Information Education Communication (IEC). For the duration of the epidemic that lasted up to 16 January 2001, a total of 425 cases with 224 deaths were reported countrywide. The case fatality rate was 53%. The attack rate (AR) was highest in women. The average AR for Gulu district was 12.6 cases/10 000 inhabitants when the contacts of all cases were considered and was 4.5 cases/10 000 if limited only to contacts of laboratory confirmed cases. The secondary AR was 2.5% when nearly 5000 contacts were followed up for 21 days. Uganda was finally declared Ebola free on 27 February 2001, 42 days after the last case

    Inadequate health financing is one of the major challenges health systems in low-income countries currently face. Health financing reforms are being implemented with an increasing interest in policies that abolish user fees. Data from three nationally representative surveys conducted in Uganda in 1999/2000, 2002/03 and 2005/06 were used to investigate the impact of user fee abolition on the attainment of universal coverage objectives. An increase in illness reporting was noted over the three surveys, especially among the poorer quintiles. An increase in utilization was registered in the period immediately following the abolition of user fees and was most pronounced in the poorest quintile. Overall, there was an increase in utilization in both public and private health care delivery sectors, but only at clinic and health centre level, not at hospitals. Our study shows important changes in health-care-seeking behaviour. In 2002/03, the poorest population quintile started using government health centres more often than private clinics whereas in 1999/2000 private clinics were the main source of health care. The richest quintile has increasingly used private clinics. Overall, it appears that the private sector remains a significant source of health care. Following abolition of user fees, we note an increase in the use of lower levels of care with subsequent reductions in use of hospitals. Total annual average expenditures on health per household remained fairly stable between the 1999/2000 and 2002/03 surveys. There was, however, an increase of US$21 in expenditure between the 2002/03 and 2005/06 surveys. Abolition of user fees improved access to health services and efficiency in utilization. On the negative side is the fact that financial protection is yet to be achieved. Out-of-pocket expenditure remains high and mainly affects the poorer population quintiles. A dual system seems to have emerged where wealthier population groups are switching to the private sector.

  13. Paleozoic oil/gas shale reservoirs in southern Tunisia: An overview

    Soua, Mohamed

    2014-12-01

    During these last years, considerable attention has been given to unconventional oil and gas shale in northern Africa where the most productive Paleozoic basins are located (e.g. Berkine, Illizi, Kufra, Murzuk, Tindouf, Ahnet, Oued Mya, Mouydir, etc.). In most petroleum systems, which characterize these basins, the Silurian played the main role in hydrocarbon generation with two main 'hot' shale levels distributed in different locations (basins) and their deposition was restricted to the Rhuddanian (Lllandovery: early Silurian) and the Ludlow-Pridoli (late Silurian). A third major hot shale level had been identified in the Frasnian (Upper Devonian). Southern Tunisia is characterized by three main Paleozoic sedimentary basins, which are from North to South, the southern Chotts, Jeffara and Berkine Basin. They are separated by a major roughly E-W trending lower Paleozoic structural high, which encompass the Mehrez-Oued Hamous uplift to the West (Algeria) and the Nefusa uplift to the East (Libya), passing by the Touggourt-Talemzane-PGA-Bou Namcha (TTPB) structure close to southern Tunisia. The forementioned major source rocks in southern Tunisia are defined by hot shales with elevated Gamma ray values often exceeding 1400 API (in Hayatt-1 well), deposited in deep water environments during short lived (c. 2 Ma) periods of anoxia. In the course of this review, thickness, distribution and maturity maps have been established for each hot shale level using data for more than 70 wells located in both Tunisia and Algeria. Mineralogical modeling was achieved using Spectral Gamma Ray data (U, Th, K), SopectroLith logs (to acquire data for Fe, Si and Ti) and Elemental Capture Spectroscopy (ECS). The latter technique provided data for quartz, pyrite, carbonate, clay and Sulfur. In addition to this, the Gamma Ray (GR), Neutron Porosity (ΦN), deep Resistivity (Rt) and Bulk Density (ρb) logs were used to model bulk mineralogy and lithology. Biostratigraphic and complete

    Contrasting to the northward African plate motion toward Eurasia and due to its geographic position in the North African margin, since early cretaceous, Tunisia seems to be submitted to an eastward migration. The aim of this work is to study the southern branch of this inferred tectonic splay that may guide the Tunisian extrusion characterised to the east by the Mediterranean sea as a free eastern boundary. The Jeffara Fault zone (southern Tunisia), represent a case example of such deformation faced by Tunisia. Helped by the results of previous researchers (Bouaziz, 1995 ; Rabiaa, 1998 ; Touati et Rodgers, 1998 ; Sokoutis D. et al., 2000 ; Bouaziz et al., 2002 ; Jallouli et al., 2005 ; Deffontaines et al., 2008…), and new evidences developed in this study, we propose a geodynamic Tunisian east extrusion model, due to such the northern African plate migration to the Eurasian one. In this subject, structural geomorphology is undertaken herein based on both geomorphometric drainage network analysis (Deffontaines et al., 1990), the Digital Terrain Model photo-interpretation (SRTM) combined with photo-interpretation of detailed optical images (Landsat ETM+), and confirmed by field work and numerous seismic profiles at depth. All these informations were then integrated within a GIS (Geodatabase) (Deffontaines 1990 ; Deffontaines et al. 1994 ; Deffontaines, 2000 ; Slama, 2008 ; Deffontaines, 2008) and are coherent with the eastern extrusion of the Sahel block. We infer that the NW-SE Gafsa-Tozeur, which continue to the Jeffara major fault zone acting as a transtensive right lateral motion since early cretaceous is the southern branch of the Sahel block extrusion. Our structural analyses prove the presence of NW-SE right lateral en-echelon tension gashes, NW-SE aligned salt diapirs, numerous folds offsets, en-echelon folds, and so on that parallel this major NW-SE transtensive extrusion fault zone.These evidences confirm the fact that the NW-SE Jeffara faults correspond

    Neurosurgery in Uganda was virtually non-existent up until late 1960s. This changed when Dr. Jovan Kiryabwire spearheaded development of a neurosurgical unit at Mulago Hospital in Kampala. His work ethic and vision set the stage for rapid expansion of neurosurgical care in Uganda.At the beginning of the 2000s, Uganda was a country of nearly 30 million people, but had only 4 neurosurgeons. Neurosurgery's progress was plagued by challenges faced by many developing countries, such as difficulty retaining specialists, lack of modern hospital resources, and scarce training facilities. To combat these challenges 2 distinct programs were launched: 1 by Dr. Benjamin Warf in collaboration with CURE International, and the other by Dr. Michael Haglund from Duke University. Dr. Warf's program focused on establishing a facility for pediatric neurosurgery. Dr. Haglund's program to increase neurosurgical capacity was founded on a "4 T's Paradigm": Technology, Twinning, Training, and Top-Down. Embedded within this paradigm was the notion that Uganda needed to train its own people to become neurosurgeons, and thus Duke helped establish the country's first neurosurgery residency training program.Efforts from overseas, including the tireless work of Dr. Benjamin Warf, have saved thousands of children's lives. The influx of the Duke Program caused a dynamic shift at Mulago Hospital with dramatic effects, as evidenced by the substantial increase in neurosurgical capacity. The future looks bright for neurosurgery in Uganda and it all traces back to a rural village where 1 man had a vision to help the people of his country.

    In early February 2014, an outbreak of the Ebola virus disease caused by Zaire ebolavirus (EBOV) occurred in Guinea; cases were also recorded in other West African countries with a combined population of approximately 25 million. A rapid, sensitive and inexpensive method for detecting EBOV is needed to effectively control such outbreak. Here, we report a real-time reverse-transcription PCR assay for Z. ebolavirus detection used by the Specialized Anti-epidemic Team of the Russian Federation during the Ebola virus disease prevention mission in the Republic of Guinea. The analytical sensitivity of the assay is 5 × 10(2) viral particles per ml, and high specificity is demonstrated using representative sampling of viral, bacterial and human nucleic acids. This assay can be applied successfully for detecting the West African strains of Z. ebolavirus as well as on strains isolated in the Democratic Republic of the Congo in 2014.

    Full Text Available In Tunisia, many people collect wild edible mushrooms as pickers for their own consumption. The present work aims at contributing to the determination of the chemical composition, non volatile components content (soluble sugars, free amino acids and minerals and trace elements of three popular Tunisian wild edible mushrooms species collected from the northwest of Tunisia (Agaricus campestris, Boletus edulis and Cantharellus cibarius.All investigated mushrooms revealed that these species are rich sources of proteins (123.70 – 374.10 g kg-1 dry weight (DW and carbohydrates (403.3 – 722.40 g kg-1 DW, and low content of fat (28.2 – 39.9 g kg-1 DW; the highest energetic contribution was guaranteed by C. cibarius (1542.71 kJ / 100 g. A. compestris (33.14 mg/g DW showed the highest concentration of essential amino acids. The composition in individual sugars was also determined, mannitol and trehalose being the most abundant sugars. C. cibarius revealed the highest concentrations of carbohydrates (722.4 g kg-1 DW and A. compestris the lowest concentration (403.3 g kg-1 DW. Potassium (K and sodium (Na are the most abundant minerals in analyzed samples (A. compestris showed the highest concentrations of K and Na, 49141.44 and 9263.886 µg/g DW respectively.

  6. ‘This Is Real Misery’: Experiences of Women Denied Legal Abortion in Tunisia

    2015-01-01

    Barriers to accessing legal abortion services in Tunisia are increasing, despite a liberal abortion law, and women are often denied wanted legal abortion services. In this paper, we seek to explore the reasons for abortion denial and whether these reasons had a legal or medical basis. We also identify barriers women faced in accessing abortion and make recommendations for improved access to quality abortion care. We recruited women immediately after they had been turned away from legal abortion services at two facilities in Tunis, Tunisia. Thirteen women consented to participate in qualitative interviews two months after they were turned away from the facility. Women were denied abortion care on the day they were recruited due to three main reasons: gestational age, health conditions, and logistical barriers. Nine women ultimately terminated their pregnancies at another facility, and four women carried to term. None of the women attempted illegal abortion services or self-induction. Further research is needed in order to assess abortion denial from the perspective of providers and medical staff. PMID:26684189

    Full Text Available Purpose – The purpose of this paper is to evaluate the impact of corruption on the environmental quality in Tunisia. Indeed, the post-revolution period is characterized by a remarkable increase in the rates of corruption. Design/methodology/approach – The direct and indirect effects of control corruption on economic growth and CO2 emissions in Tunisia have been examined using the autoregressive distributed lag (ARDL cointegration framework among corruption, growth and CO2 emissions. Findings – Results substantiate a positive and significant relationship between control of corruption and economic growth, a negative and significant relationship between control of corruption and environmental quality (CO2 and a negative and significant relationship between control of corruption and energy consumption. The findings suggest that while the control of corruption contributes to economic growth, its positive effect could be transposed indirectly via its impacts on environmental quality. Originality/value – A strategy against corruption will reduce CO2 emissions; however, its positive effect on economic growth indirectly contributes to reverse this relationship.

    At Sahel, near one of the seaside resort available in Tunisia, the water quantity and quality is a major problem ever at southern center of Tunisia. The Oued Laya coastal system is no exception. The levels, a shallow aquifer up to depths of about 60 m whose reservoir is mainly formed by Mio-Pliocnesediments (with some gypsum lenses dispersed within the geological formations) and deep aquifer, situated between 100 and 250 m depth, located in the Miocene sandstone formations. The results of geochemical and isotopic studies have shown that groundwater salinity seems not be linked with the increasing water well's abstraction. In contrast, water mineralization seems to acquired by dissolution of minerals in the aquifer system especially halie and gypsum. Besides ion exchange processes play also an important role in the groundwater mineralization. Therefore, it clearly appears that several sources might contribute with different mineralization to the selenization of the aquifer through the natural recharge and also through the return of water irrigation. The contamination of the Mio-Pliocene shallow aquifer by a mixture with seawater is confirmed, and stable isotopes data do not support the hypothesis of mixing with seawater. (Author)

  9. Does financial development increase energy consumption? The role of industrialization and urbanization in Tunisia

    Shahbaz, Muhammad; Lean, Hooi Hooi

    2012-01-01

    This paper assesses the relationship among energy consumption, financial development, economic growth, industrialization and urbanization in Tunisia from 1971 to 2008. The autoregressive distributed lag bounds testing approach to cointegration and Granger causality tests is employed for the analysis. The result confirms the existence of long-run relationship among energy consumption, economic growth, financial development, industrialization and urbanization in Tunisia. Long-run bidirectional causalities are found between financial development and energy consumption, financial development and industrialization, and industrialization and energy consumption. Hence, sound and developed financial system that can attract investors, boost the stock market and improve the efficiency of economic activities should be encouraged in the country. Nevertheless, promoting industrialization and urbanization can never be left out from the process of development. We add light to policy makers with the role of financial development, industrialization and urbanization in the process of economic development. - Highlights: ► We find the existence of long-run relationship among variables. ► Financial development is positively related to energy consumption. ► Bidirectional causal relationship between financial development and energy consumption. ► Sound and developed financial system should be encouraged.

    Mental disorders have been associated worldwide with human rights' violations. Controversially, many occur in mental health facilities. This work aimed to assess the rights of people with mental disorders in healthcare facilities in Tunisia. A cross-sectional study, using the World Health Organization (WHO) quality-rights toolkit, assessed the human rights levels of achievement in Elrazi Hospital, the only psychiatric hospital in Tunisia, in comparison with the National Institute of Nutrition (NIN). The framework was the Convention on the Rights of Persons with Disabilities (CRPD). The assessment was carried through observation, documentation review, and interviews with service users, staff, and family members. The sample was composed of 113 interviewees. In Elrazi Hospital, three out of the five evaluated rights were assessed as only initiated: the right to an adequate standard of living, to exercise legal capacity and to be free from inhuman treatment. By comparison, these rights were partially achieved in the NIN. The right to enjoyment of the highest attainable standard of health was partially achieved and the right to live independently and to be included in the community was not even initiated. These last two rights were at the same level of achievement in the NIN. Significant improvements are needed to adapt the practice in Elrazi Hospital to comply with human rights, especially since the achievement level of these rights is lower than in a non-psychiatric hospital. Our study emphasizes the importance of spreading the CRPD as a standardized framework.

  11. Comparative analysis of climate change vulnerability assessments. Lessons from Tunisia and Indonesia

    2013-03-15

    Vulnerability assessments (VAs) are central to shaping climate change adaptation decisions. They help to define the nature and extent of the threat that may harm a given human or ecological system, providing a basis for devising measures that will minimize or avoid this harm. Yet the wide variety of VA approaches can be confusing for practitioners, creating uncertainty about the ''right'' way to assess vulnerability. In an effort to provide some guidance on designing and conducting VAs, this paper reviews and compares VAs undertaken in Indonesia and Tunisia to distill key approaches, components and lessons. It begins with a general overview of definitions, approaches and challenges with conducting VAs, and then proposes a framework for analyzing and comparing them. The framework looks at four components of VAs: (1) Framing: where do we come from? (2) Process of conducting the VAs: how does it work? (3) Inputs: what is needed? (4) Outputs: what does it tell us? The framework is then applied to analyze the assessments carried out in Tunisia and Indonesia, from their respective framings of vulnerability to the outputs of the process. The report then concludes with observations on differences and similarities between the VAs, as well as lessons learned that can inform the design and execution of future assessments.

    Full Text Available Abstract Background Italy and Tunisia (Africa for the Romans, facing each other on the opposite sides of the Mediterranean Sea, have been historically linked since the ancient times. Over the centuries both countries were mutually dominated so the vestiges and traces of a mutual influence are still present. The aim of the present study is to conduct a comparative analysis of the medicinal species present in the respective Floras in order to explore potential analogies and differences in popular phytotherapy that have come out from those reciprocal exchanges having taken place over the centuries Methods The comparative analysis based on the respective floras of both countries takes into consideration the bulk of medicinal species mutually present in Italy and Tunisia, but it focuses on the species growing in areas which are similar in climate. The medicinal uses of these species are considered in accordance with the ethnobotanical literature. Results A list of 153 medicinal species belonging to 60 families, present in both floras and used in traditional medicine, was drawn. A considerable convergence in therapeutic uses of many species emerged from these data. Conclusion This comparative analysis strengthens the firm belief that ethno-botanical findings represent not only an important shared heritage, developed over the centuries, but also a considerable mass of data that should be exploited in order to provide new and useful knowledge.

  13. THE HYBRID APPROACH OF INFLATION TARGETING: WHAT OPPORTUNITIES FOR AN EMERGING ECONOMY LIKE TUNISIA?

    Directory of Open Access Journals (Sweden)

    Hella Guerchi Mehri

    2016-07-01

    Full Text Available After economic crises happening in many emerging countries, flexible exchange rates became a required theoretical condition helping to target inflation. Many countries stopped using exchange rate as an anchor for monetary policy and started using inflation targeting framework. In emerging countries, monetary authorities work to stabilize the exchange rate because of their “fear of floating”. They are against high volatility of interest rate allowing speculative attacks and causing free fluctuations of their national currency. To avoid uncontrolled market movements, they have to choose between active and public exchange rate management and tight inflation targeting. In the same vein, Central bank of Tunisia follows financial measures linked closely to inflation without focusing especially on monetary aggregates in order to study a possible transition to targeting inflation strategy. It uses a simple Taylor rule where interest rates adjustment are guided by the anticipated inflation deviation from its original target and also by the gap between observed and potential GDP.As an emerging economy with a high degree of financial vulnerability, and facing different shocks, Tunisia should adopt a hybrid rule of inflation targeting in an open economy. This hybrid rule explicitly takes into account the evolution of the exchange rate in the reaction function of the central bank.

    In Tunisia and other North African countries, there is a lack of knowledge about parasite biodiversity within threatened wild ruminants and there are not any studies on their gastrointestinal nematodes. Thus the aim of this study was to identify gastrointestinal fauna in the faecal samples of Tunisian wild ruminants. A total of 262 faecal samples were collected from domestic sheep and goat, and wild ruminants (Addax, Barbary sheep, Barbary red deer, Dorcas gazelle, Slender-horned gazelle and Scimitar-horned Oryx) living in protected areas. Samples were examined with floatation (saturated sodium chloride solution), polymerase chain reaction and sequencing of the second internal transcribed spacer region of the rDNA. Microscopic analysis allowed the identification of only Nematodirus genus or molecular tools allowed a first identification of five gastrointestinal nematode species in North African wild ruminants: Chabertia ovina (1.6%), Camelostrongylus mentulatus (1.6%), Marshallagia marshalli (4.7%), Nematodirus helvetianus (62.5%) and Nematodirus spathiger (29.7%). This study reported the first records of C. mentulatus and M. marshalli in Addax and of M. marshalli in Dorcas gazelle and it was the first reported record of N. helvetianus and M. marshalli in Tunisia.

    There is an increasing prevalence of obesity and metabolic syndrome (MS) in developing countries. It has been shown the relationship between social class and MS in developed countries. The objective of our study was to compare the association of social class with the prevalence of MS in a developing country (Tunisia, region of Cap-Bon) and a developed one (Spain, Canary Islands). Cross-sectional study of 6729 Canarian and 393 Tunisian individuals. Social class was measured with the income, crowding and education (ICE) model, which includes family income, household crowding and education level. Logistic regression models adjusted by age estimated the risk by odds ratio (OR) and confidence interval (CI 95 %) of MS according to social class. MS prevalence was higher in Tunisian (50 %) than in Canarian women (29 %; p = 0.002), with no significant differences between men. For Canarian women, being in the highest social class was a protective factor against MS (OR = 0.39; CI 95 % 0.29-0.53) and all its components. The Canarian population and the Tunisian women, showed a significant linear trend (p social class increased. High social class is a protective factor from MS and its components within the Canarian population and the Tunisian women. Our results suggest that the socioeconomic transition in a developing country like Tunisia can improve the population health in a sex-specific manner.

    This paper focuses on a case study of financing an integrated nuclear desalination system at la Skhira site in Tunisia. More specifically, it shows the financial characteristics of the study, known as the TUNDESAL project, the main financing mechanisms that can be used, and the principal actions required to attract the potential investors and lenders. The paper describes: - The specific financial considerations corresponding to the particular characteristics of nuclear desalination projects: high capital costs, high level of risks and uncertainties, relatively long construction lead times and social and environmental concerns; - The main risks involved in nuclear energy projects; - The profitability study of the TUNDESAL project with the application of the Discounted Cash Flow Analysis; - The main financing sources for the project; - The financing schemes that can be used for project implementation and comparison between these schemes in terms of benefits generated, after covering project costs and repayment of lenders and investors; - The main actions to be done for making the project financially attractive in order to gain the confidence of investors and international financial institutions (optimal allocation of project risks and uncertainties, a suitable and flexible energy and water tariffs policy). Analysis has shown that in particular conditions of Tunisia, the most attractive financial scheme could be the 'project financing + leasing'. (authors)

    Vulnerability assessments (VAs) are central to shaping climate change adaptation decisions. They help to define the nature and extent of the threat that may harm a given human or ecological system, providing a basis for devising measures that will minimize or avoid this harm. Yet the wide variety of VA approaches can be confusing for practitioners, creating uncertainty about the ''right'' way to assess vulnerability. In an effort to provide some guidance on designing and conducting VAs, this paper reviews and compares VAs undertaken in Indonesia and Tunisia to distill key approaches, components and lessons. It begins with a general overview of definitions, approaches and challenges with conducting VAs, and then proposes a framework for analyzing and comparing them. The framework looks at four components of VAs: (1) Framing: where do we come from? (2) Process of conducting the VAs: how does it work? (3) Inputs: what is needed? (4) Outputs: what does it tell us? The framework is then applied to analyze the assessments carried out in Tunisia and Indonesia, from their respective framings of vulnerability to the outputs of the process. The report then concludes with observations on differences and similarities between the VAs, as well as lessons learned that can inform the design and execution of future assessments.

    Within the framework of the Tunisian - EC SALTO/AVICENNE project, four hydrological sections were performed between Tunisia, Sardinia and Sicily with a 10-20 km sampling interval in April-June 1995. To our knowledge, it is the first time that sections were repeated there at such a high frequency. These data significantly increase the number of observations available on the Tunisian side of the Channels of Sardinia and Sicily, and allow reliable specification of the hydrological characteristics of the area. For the first time, and as confirmed by infrared satellite images, these data sets show (i) the large mesoscale variability of the surface flow entering the study area, as expected from the characteristics of the Algerian Current upstream, (ii) the rapid changes it undergoes around northeastern Tunisia, as it shifts roughly from southward to eastward within less than a few weeks. These data also show a large heterogeneity at intermediate levels, clearly associated with waters of very different origins that follow converging routes and mix in both the study area and the southern Tyrrhenian Sea. They finally document the fundamental importance of bathymetric features of relatively small scale such as the Skerki passage.

    Chronic Obstructive Pulmonary Disease is defined by a limitation of airflow. This disease is characterized by exacerbations that threaten the patient's life and worsens his prognosis. Moreover, COPD patients are different according to many parameters that define different phenotypes. Characteristics of exacerbations may depend on these phenotypes according to few recent studies. To determine the characteristics and the prognosis of the exacerbations in each phenotype of COPD patients phenotype in Tunisia. Retrospective study including 153 male patients hospitalized for COPD exacerbation from January 2009 to June 2012. Patients were classified into 4 phenotypes according to Burgel's classification. Patients were divided into four phenotypes: phenotype (PH)1: (n=68), PH2: (n=33), PH3: (n=25) and PH4: (n=27). Mean age for PH1, 2, 3 and 4 was: 61, 74, 56 and 72 years. The number of exacerbations per year was higher in PH1. Dyspnea was more important in PH1 and 4. Hypercapnia on admission was higher in PH4. Non invasive ventilation and transfer to resuscitation unit were more frequently mandatory in PH3 and 4.   Death occurred 2% of PH1 and 5% of PH4. Hospitalization duration was more important in PH4. COPD patients are heterogenous and belong to different phenotypes. The characteristics of the exacerbations and their prognosis widely differ according to these different groups. In Tunisia, it seems that patients who had moderate respiratory functional tests impairment are the lowest responders to treatment with a higher frequency of resuscitation unit transfer.

    Full Text Available Aim of study: The aim of the work was to develop an individual tree diameter-increment model for Thuya (Tetraclinis articulata in Tunisia.Area of study: The natural Tetraclinis articulata stands at Jbel Lattrech in north-eastern of Tunisia.Material and methods:  Data came from 200 trees located in 50 sample plots. The diameter at age t and the diameter increment for the last five years obtained from cores taken at breast height were measured for each tree. Four difference equations derived from the base functions of Richards, Lundqvist, Hossfeld IV and Weibull were tested using the age-independent formulations of the growth functions. Both numerical and graphical analyses were used to evaluate the performance of the candidate models.Main results: Based on the analysis, the age-independent difference equation derived from the base function Richards model was selected. Two of the three parameters (growth rate and shape parameter of the retained model were related to site quality, represented by a Growth Index, stand density and the basal area in larger trees divided by diameter of the subject tree expressing the inter-tree competition.Research highlights: The proposed model can be useful for predicting the diameter growth of Tetraclinis articulata in Tunisia when age is not available or for trees growing in uneven-aged stands.Keywords: Age-independent growth model; difference equations; Tetraclinis articulata; Tunisia.

    Echinococcus granulosus sensu lato (s.l.) is a zoonotic disease highly endemic in Tunisia. Canids including stray and semi-stray dogs, jackals and foxes are known as definitive hosts and a wide range of ungulates have been shown to harbour the metacestode hydatid stage and may serve as intermediate hosts. Fertile hydatid cysts of Echinococcus equinus and E. granulosus sensu stricto (s.s.) were recently molecularly identified for the first time from Tunisian donkeys. E. granulosus (s.s.) was also identified from wild boars in Tunisia. Here we report the confirmation of hydatid cysts caused by E. granulosus (s.s.) in the critically endangered antelope, Addax nasomaculatus in Tunisia. DNA-based molecular analysis revealed that A. nasomaculatus was infected with E. granulosus (s.s.) which had a 100% identity with the main globally distributed E. granulosus (s.s.) (EgTu01) haplotype. Cysts of Taenia hydatigena (n=33) were also observed on the liver and in the body cavity. Due to their endangered status and their relatively small numbers, it is unlikely that hydatid infection of A. nasomaculatus will form a major contribution to the epidemiology and transmission of E. granulosus in Tunisia, but infection may result in pathology, morbidity and early mortality, and may still play a role in the perpetuation of the parasite in wildlife cycles.

    The study of the solar radiation is the starting point of any investigation for a new energy, to study and search the best location to install a PV system. A very important factor in the assessment of solar potential is the availability of data for global solar radiation that must be coherent and of high quality. In this paper, we analyze the estimation result of the monthly global solar radiation for three different locations, Bizerte in Northern Tunisia, Kairouan in Middle Eastern Tunisia, and Tozeur in Southern Tunisia, measured on the surface by the National Institute of Meteorology and the meteorological year irradiation based on satellite imagery result PVGIS radiation databases. To get the right measurements with minimum error, we propose a numerical model used to calculate the global solar radiation in the indicated three sites. The results show that the model can estimate the global solar radiation (kWh/m²) at a specific station and over most area of Tunisia. The model gives a good estimation for solar radiation where error between the measured values and those calculated are negligible.

    Plague is a highly virulent fleaborne zoonosis that occurs throughout many parts of the world; most suspected human cases are reported from resource-poor settings in sub-Saharan Africa. During 2008-2016, a combination of active surveillance and laboratory testing in the plague-endemic West Nile region of Uganda yielded 255 suspected human plague cases; approximately one third were laboratory confirmed by bacterial culture or serology. Although the mortality rate was 7% among suspected cases, it was 26% among persons with laboratory-confirmed plague. Reports of an unusual number of dead rats in a patient's village around the time of illness onset was significantly associated with laboratory confirmation of plague. This descriptive summary of human plague in Uganda highlights the episodic nature of the disease, as well as the potential that, even in endemic areas, illnesses of other etiologies might be being mistaken for plague.

  10. Perceptions of sexual coercion among young women in Uganda.

    Hayer, Manvir Kaur

    2010-01-01

    This paper sets out to explore Ugandan young women's definitions and perceptions of sexual coercion. A qualitative study was conducted with seven young women in rural Uganda. Participants filmed videos, wrote stories, made drawings and participated in transect walks before analysing their data through formal and informal discussions. Forced sex is defined narrowly to mean only rape. Verbal forms of sexual coercion were recognised, but only after some discussion. Verbal coercion is referred to as "abusing" or "convincing". Young women are commonly pressured into consenting to have sex, despite what they really want, owing to the socio-cultural circumstances. Young women in Uganda are significantly tolerant of sexual coercion. This tolerance appears to arise from power differentials between genders, and the socio-cultural environment shaping their lives. The paper improves understanding of young women's definitions and perceptions of sexual coercion, which is essential to provide effective violence prevention programmes. It also suggests that further research is warranted in this field.

    This chapter addresses private sector investment in the production of households renewable energy technologies (RETs) and provides recommendations for the large-scale manufacture and dissemination of these RETs in Uganda. The following four RETs are examined in detail: improved households cookstoves, institutional stoves, biomass briquettes and biogas. The household energy sector in Uganda relies heavily on biomass, with fuelwood providing 95.5 per cent, followed by charcoal which accounts for 2.7 per cent. Petroleum products and electricity contribute 1.4 per cent and 0.5 per cent, respectively. Charcoal and fuelwood are used mainly in the open fire and the traditional metal stove whose efficiencies are very low. In parts of the country where the fuelwood deficit is imminent, agricultural wastes are the major substitutes. (Author)

  12. Evaluating the MSG satellite Multi-Sensor Precipitation Estimate for extreme rainfall monitoring over northern Tunisia

    Full Text Available Knowledge and evaluation of extreme precipitation is important for water resources and flood risk management, soil and land degradation, and other environmental issues. Due to the high potential threat to local infrastructure, such as buildings, roads and power supplies, heavy precipitation can have an important social and economic impact on society. At present, satellite derived precipitation estimates are becoming more readily available. This paper aims to investigate the potential use of the Meteosat Second Generation (MSG Multi-Sensor Precipitation Estimate (MPE for extreme rainfall assessment in Tunisia. The MSGMPE data combine microwave rain rate estimations with SEVIRI thermal infrared channel data, using an EUMETSAT production chain in near real time mode. The MPE data can therefore be used in a now-casting mode, and are potentially useful for extreme weather early warning and monitoring. Daily precipitation observed across an in situ gauge network in the north of Tunisia were used during the period 2007–2009 for validation of the MPE extreme event data. As a first test of the MSGMPE product's performance, very light to moderate rainfall classes, occurring between January and October 2007, were evaluated. Extreme rainfall events were then selected, using a threshold criterion for large rainfall depth (>50 mm/day occurring at least at one ground station. Spatial interpolation methods were applied to generate rainfall maps for the drier summer season (from May to October and the wet winter season (from November to April. Interpolated gauge rainfall maps were then compared to MSGMPE data available from the EUMETSAT UMARF archive or from the GEONETCast direct dissemination system. The summation of the MPE data at 5 and/or 15 min time intervals over a 24 h period, provided a basis for comparison. The MSGMPE product was not very effective in the detection of very light and light rain events. Better results were obtained for the slightly

    Full Text Available Cattle and poultry enterprises are among the major contributors to food security and socioeconomic empowerment of households in Uganda. However, various diseases constrain their productivity. A two-year retrospective study between April 2012 and March 2014 was conducted using records for cattle and poultry diseases diagnosed at the Central Diagnostic Laboratory (CDL to determine prevalent diseases in Uganda. The laboratory received 836 samples from poultry (36.3% and cattle (63.7%. Of the 836 samples, 47.5% had a definitive diagnosis of disease causation. Most of the cattle and poultry diseases diagnosed were protozoan diseases (39.3% followed by bacterial (21.4%, viral (17.1%, helminthiasis (11.1%, nutritional diseases (4% and others (7.1%. For poultry, viral diseases (29.5% and protozoan diseases (27.1% especially newcastle disease (44.3% and coccidiosis (100% respectively, were the most diagnosed. While for cattle, hemo-protozoan parasites (52.1% were the most prevalent, of which 92.9% were east coast fever infection. Bacterial infection (20.5% in cattle were the second most diagnosed diseases and mastitis was the most diagnosed (46.2%. In summary, coccidioisis, collibacillosis, newcastle disease, gumboro disease, and avian helminthiasis were the most prevalent poultry diseases while in cattle, east coast fever, helminthiasis, mastitis, brucellosis and rabies were the most frequently diagnosed diseases. This study has identified the major diseases that hinder poultry and cattle production in Uganda. The data generated by CDL could be used for surveillance, monitoring and designing strategic interventions for control of poultry and cattle diseases in Uganda.

    Despite current efforts to combat HIV/AIDS through behavioural change, ingrained socio-cultural practices such as widow inheritance in south-western Uganda has not changed. Low education, unemployment, dowry, widows' socioeconomic demands and the inheritor's greed for the deceased's wealth, influence widow inheritance. Voluntary counselling and testing is needed for the widows and their inheritors; formal dowry should be removed from marriage and widow inheritance stripped of its sexual component.

  20. Dismantling reified African culture through localised homosexualities in Uganda.

    Science.gov (United States)

    Nyanzi, Stella

    2013-01-01

    Uganda's Anti-Homosexuality Bill of 2009 aimed at protecting the cherished culture of the people against emergent threats to the traditional heterosexual family. The Bill's justification, however, lay in myopic imaginings of a homogenous African-ness and pedestrian oblivion to pluralities within African sexualities. This paper revisits the debate that homosexuality is 'un-African'. Rhetoric analysis of the Anti-Homosexuality Bill exposes how dominant discourses of law, medicine, religion, geography and culture reinforce the view that homosexuality is foreign to Africa. Based on ethnography in contemporary Uganda, I explore how self-identified same-sex-loving individuals simultaneously claim their African-ness and their homosexuality. Their strategies include ethnic belonging, membership to kinship structures, making connections with pre-colonial histories of homosexuality, civic participation in democratic processes, national identity, organising of lesbian, gay, bisexual, transgender, intersex and questioning support groups, language and nomenclature, visibility and voice in local communal activities, solidarity and adherence to cultural rituals. In present-day Uganda, same-sex-loving men, women and transgender people variously assert their African-ness.

    2013-01-01

    Full Text Available Orientation: This article focused on the need for improved employer-employee relationships in order for public universities in Uganda to achieve their intended objectives.Research purpose: The purpose of this article was to review the need for appropriate employer-employee relationships that will ensure quality services and service delivery in public universities in Uganda.Motivation for the study: The researchers set out to examine why managers of public universities in Uganda were continuously paying less attention to the needs of the employees.Research design, approach and method: A descriptive research design was employed and 12 respondents, purposively selected from 4 public universities, were interviewed. Data were recorded, transcribed and analysed using Nvivo software. This article is based on the perspective of agency theory, and discussed the contractual relationship between management and employees. The agency theory was deemed necessary because of its contribution to organisational literature.Main findings: There is a need to create and nurture a collegial working climate that promotes quality interactions through information sharing. This results in creating and retaining motivated and committed employees, and also helps to overcome the paradox of balancing the high demand for university education whilst offering quality services.Practical/managerial implications: Managers have to continuously monitor and accommodate employee needs and demands.Contribution/value-add: The potential value of the paper is its function as a guide for public universities to have visionary managers that will introduce new approaches to managing public universities in a competitive global environment.

    The expiry of medicines in the supply chain is a serious threat to the already constrained access to medicines in developing countries. We investigated the extent of, and the main contributing factors to, expiry of medicines in medicine supply outlets in Kampala and Entebbe, Uganda. A cross-sectional survey of six public and 32 private medicine outlets was done using semi-structured questionnaires. The study area has 19 public medicine outlets (three non-profit wholesalers, 16 hospital stores/pharmacies), 123 private wholesale pharmacies and 173 retail pharmacies, equivalent to about 70% of the country's pharmaceutical businesses. Our findings indicate that medicines prone to expiry include those used for vertical programmes, donated medicines and those with a slow turnover. Awareness about the threat of expiry of medicines to the delivery of health services has increased. We have adapted training modules to emphasize management of medicine expiry for pharmacy students, pharmacists and other persons handling medicines. Our work has also generated more research interest on medicine expiry in Uganda. Even essential medicines expire in the supply chain in Uganda. Sound coordination is needed between public medicine wholesalers and their clients to harmonize procurement and consumption as well as with vertical programmes to prevent duplicate procurement. Additionally, national medicine regulatory authorities should enforce existing international guidelines to prevent dumping of donated medicine. Medicine selection and quantification should be matched with consumer tastes and prescribing habits. Lean supply and stock rotation should be considered.

    Development in organic farming has been stimulated by farmers and consumers becoming interested in healthy food products and sustainable environment. Organic agriculture is a holistic production management system which is based on the principles of health, ecology, care, and fairness. Organic development in Uganda has focused more on the crop sector than livestock sector and has primarily involved the private sector, like organic products export companies and non-governmental organizations. Agriculture in Uganda and many African countries is predominantly traditional, less mechanized, and is usually associated with minimum use of chemical fertilizers, pesticides, and drugs. This low external input agriculture also referred to as "organic by default" can create basis for organic farming where agroecological methods are introduced and present an alternative in terms of intensification to the current low-input/low-output systems. Traditional farming should not be confused with organic farming because in some cases, the existing traditional practices have consequences like overstocking and less attention to soil improvement as well as to animal health and welfare, which is contrary to organic principles of ecology, fairness, health, and care. Challenges of implementing sustainable organic practices in the Ugandan livestock sector threaten its future development, such as vectors and vector-borne diseases, organic feed insufficiency, limited education, research, and support to organic livestock production. The prospects of organic livestock development in Uganda can be enhanced with more scientific research in organic livestock production under local conditions and strengthening institutional support.

    Low contraceptive uptake and high unmet need for contraception remain significant issues in Uganda compared to neighboring countries such as Kenya, Ethiopia, and Rwanda. Although prior research on contraceptive uptake has indicated that male partners strongly influence women's decisions around contraceptive use, there is limited in-depth qualitative research on knowledge and concerns regarding modern contraceptive methods among Ugandan men. Using in-depth interviews (N = 41), this qualitative study investigated major sources of knowledge about contraception and perceptions of contraceptive side effects among married Ugandan men. Men primarily reported knowledge of contraceptives based on partner's experience of side effects, partner's knowledge from health providers and mass media campaigns, and partner's knowledge from her peers. Men were less likely to report contraceptive knowledge from health care providers, mass media campaigns, or peers. Men's concerns about various contraceptive methods were broadly associated with failure of the method to work properly, adverse health effects on women, and severe adverse health effects on children. Own or partner's human immunodeficiency virus (HIV) status did not impact on contraceptive knowledge. Overall, we found limited accurate knowledge about contraceptive methods among men in Uganda. Moreover, fears about the side effects of modern contraceptive methods appeared to be common among men. Family planning services in Uganda could be significantly strengthened by renewed efforts to focus on men's knowledge, fears, and misconceptions.

    Full Text Available The development of environmental regulatory framework in Uganda was initiated by the national environment action planning process in 1990, as a realization that environment needed special focus. As a result of the said process environmental policy and law were developed. The 1995 constitutional of the Republic of Uganda was among the first ever such constitution in the East African region to deliberately enshrine the right to a decent environment and to provide for sustainable development, in addition to the principle that natural resources are held in trust for the people and should be responsibly managed for their benefit. Following the constitution, a number of environment legislations were enacted and others were revised to take into account environmental cardinal principles and considerations, including embedding in them environmental regulatory provisions. Hence, in addition to the framework of National Environment Act, a number of environment sect oral legislation exists and environmental management is spread throughout the respective institutions responsible for aspects of the environment. It is therefore safe to say that Uganda has developed a lot of legislation on the environment but the challenge remains that of developing more regulations under the relevant parent Acts, effective monitoring and enforcement.

    Full Text Available Background: The burden of non-communicable diseases (NCDs in low- and middle-income countries (LMICs is accelerating. Given that the capacity of health systems in LMICs is already strained by the weight of communicable diseases, these countries find themselves facing a double burden of disease. NCDs contribute significantly to morbidity and mortality, thereby playing a major role in the cycle of poverty, and impeding development. Methods: Integrated approaches to health service delivery and healthcare worker (HCW training will be necessary in order to successfully combat the great challenge posed by NCDs. Results: In 2013, we formed the Uganda Initiative for Integrated Management of NCDs (UINCD, a multidisciplinary research collaboration that aims to present a systems approach to integrated management of chronic disease prevention, care, and the training of HCWs. Discussion: Through broad-based stakeholder engagement, catalytic partnerships, and a collective vision, UINCD is working to reframe integrated health service delivery in Uganda.

    Brun, Annik; Guerin, Claude; Levy, Alain; Riser, Jean; Rognon, Pierre

    The cross section of the Oued el Akarit, 25 km North of Gabès, is of considerable importance for the paleoenvironmental reconstitution of South Tunisia at the end of the Upper Pleistocene. Grey or black silts and clays and greenish gray sands which overlap them, contain many paleontological remains: rodents, birds and Rhinoceros bones, Gasteropods, Foraminifera, Ostracoda and pollen. All these sedimentological, faunistic or botanical indications allow to consider that this area, between approximatively 35,000 and 22,000 yr. B.P., belonged to the steppe domaine. But this steppe was probably more dense and more diversified than the present-day steppe which receives 170 mm of rain (annual average). This conclusion is in good agreement with the other paleoenvironmental data from the Chott Djerid, the Matmata plateau or the Gulf of Gabès cores, areas situated at about 100 km to the West, the South or the East of the Oued el Akarit.

    Full Text Available Rift Valley fever virus (RVFv is capable of causing dramatic outbreaks amongst economically important animal species and is capable of causing severe symptoms and mortality in humans. RVFv is known to circulate widely throughout East Africa; serologic evidence of exposure has also been found in some northern African countries, including Mauritania. This study aimed to ascertain whether RVFv is circulating in regions beyond its known geographic range. Samples from febrile patients (n=181 and nonfebrile healthy agricultural and slaughterhouse workers (n=38 were collected during the summer of 2014 and surveyed for exposure to RVFv by both serologic tests and PCR. Of the 219 samples tested, 7.8% of nonfebrile participants showed immunoglobulin G reactivity to RVFv nucleoprotein and 8.3% of febrile patients showed immunoglobulin M reactivity, with the latter samples indicating recent exposure to the virus. Our results suggest an active circulation of RVFv and evidence of human exposure in the population of Tunisia.

    Smoking prevalence has reached high rates among health professionals. Our study aimed to assess smoking behavior, knowledge and attitudes towards anti-smoking regulations of nursing students. In 2013, we conducted a cross-sectional study among nursing students enrolled in private and state nursing institutions of Sousse (Tunisia). In our study, 440 students were selected. The mean age was 22 ± 2 years. The sex ratio was 0.65. The prevalence of smoking was 20.6%. It was significantly higher in men than women (50% vs 4.5%, P smoking. Prohibiting the sale of cigarettes to minors and smoking in enclosed public places were the two most mentioned anti-smoking regulations. Our rate was lower than those reported in the literature. This result should encourage policymakers to continue actions and ensure sustainability. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    The study area constitutes the major part of the plain of Jeffara, located at the south-east of Tunisia. This plain is characterized by an arid climate with rare and irregular pluviometry. The hydrochemical approach is used to define the chemical characteristics of the water in these aquifer systems. Indeed, the water salinity varies between 0.6g/? and 9g/?, and increases from the Daher mountains in the west to the Mediterranean Sea. The groundwaters are homogeneous and characterized by a Cl-(SO 4 ) and Na-(Ca-Mg) water type. The isotopic approach shows that the carbone-14 activities, measured in groundwater, evolve in the same direction of groundwater flow. These activities suggest a recent recharge area in eastern piedmont of the Dahar mountains, as well as the zone of the Sahel Abebsa and Zeuss-Koutine. The isotopic values confirm, also, the communication between the various major levels through the existing faults and discontinuities in this area

    In Tunisia, the expansion of irrigated area and the semiarid climate make it compulsory to adopt strategies of water management to increase water use efficiency. Subsurface drip irrigation (SDI), providing the application of high frequency small irrigation volumes below the soil surface have been increasingly used to enhance irrigation efficiency. At the same time, deficit irrigation (DI) has shown successful results with a large number of crop in various countries. However, for some crops like potatoes, DI is difficult to manage due to the rapid effect of water stress on tuber yield. Irrigation frequency is a key factor to schedule subsurface drip irrigation because, even maintaining the total seasonal volume, soil wetting patterns can result different during the growth period, with consequence on crop yield. Despite the need to enhance water use efficiency, only a few studies related to deficit irrigation of horticultural crops have been made in Tunisia. Objective of the paper was to assess the effects of different on-farm irrigation strategies on water use efficiency of potatoes crop irrigated with subsurface drip irrigation in a semiarid area of central Tunisia. After validation, Hydrus-2D model was used to simulate soil water status in the root zone, to evaluate actual crop evapotranspiration and then to estimate indirectly water use efficiency (IWUE), defined as the ratio between crop yield and total amount of water supplied with irrigation. Field experiments, were carried out in Central Tunisia (10° 33' 47.0" E, 35° 58' 8.1° N, 19 m a.s.l) on a potatoes crop planted in a sandy loam soil, during the growing season 2014, from January 15 (plantation of tubers) to May 6 (harvesting). Soil water status was monitored in two plots (T1 and T2) maintained under the same management, but different irrigation volumes, provided by a SDI system. In particular, irrigation was scheduled according to the average water content measured in the root zone, with a total of 8

    During the last decade, Tunisia evolved in an extremely difficult energy context characterized by the stabilization of the resources in hydrocarbons, the increase of the energy consumption and the increase of the price of oil ($147 the barrel in July, 2008), imposing on it to mobilize more to meet several challenges in terms of outside energetic dependence for the generation of electricity and the reduction of greenhouse gases. This policy allowed the reduction in the rate of growth of energy intensity of the country. This article presents a review about renewable and conventional energy resources, electricity consumption and production and the policy adopted by the country for energy conservation and the promotion of renewable energy.

Methods Individual PDHs capacity utilization (CU is measured for 2000 and 2010 using dual data envelopment analysis (DEA approach with shadow prices input and output restrictions. The CU is estimated for 101 of 105 PDH in 2000 and 94 of 105 PDH in 2010. Results In average, unused capacity is estimated at 18% in 2010 vs. 13% in 2000. Of PDHs 26% underutilize their operating budget in 2010 vs. 21% in 2000. Conclusion Inadequate supply, health quality and the lack of operating budget should be tackled to reduce unmet user’s needs and the bypassing of the PDHs and, thus to increase their CU. Social health insurance should be turned into a direct purchaser of curative and preventive care for the PDHs.

    2016-10-01

    Full Text Available Temporary ponds are the most peculiar and representative water bodies in the arid and semi-arid regions of the world, where they often represent diversity hotspots that greatly contribute to the regional biodiversity. Being indissolubly linked to these ecosystems, the so-called “large branchiopods” are unanimously considered flagship taxa of these habitats. Nonetheless, updated and detailed information on large branchiopod faunas is still missing in many countries or regions. Based on an extensive bibliographical review and field samplings, we provide an updated and commented checklist of large branchiopods in Tunisia, one of the less investigated countries of the Maghreb as far as inland water crustaceans are concerned. We carried out a field survey from 2004 to 2012, thereby collecting 262 crustacean samples from a total of 177 temporary water bodies scattered throughout the country. Large branchiopod crustaceans were observed in 61% of the sampled sites, leading to the identification of fifteen species. Among these, the halophilic anostracan Branchinectella media is here reported for the first time for the country; conversely, four of the species reported in literature were not found during the present survey. Based on literature and novel data, the known large branchiopod fauna of Tunisia now includes 19 species, showing a noteworthy species richness when the limited extension of the country is considered. For each species, the regional distribution is described and an annotated list of references is provided. Under a conservation perspective, the particular importance of the temporary ponds occurring in the Medjerda river alluvial plain is further stressed. In this location, several large branchiopod taxa with different ecological requirements converge and form unique and species-rich assemblages that should be preserved.

    The Government of Tunisia, U. S. Agency for International Development, and U. S. Department of Agriculture cooperatively developed a program for suppression of Ceratitis capitata (Wiedemann) in Tunisia. Mediterranean fruit flies were reared on an artificial diet, sterilized with 10 krad irradiation from a cobalt source, and the emerged adults were marked and then distributed by hand throughout the release area, 600 ha in the vicinity of Porto-Farina. Some aerial releases were made late in the season. Winter larval hosts were removed to lower the overwintering population, and sterile fly releases were begun early (Mar.1) to prevent fertile matings of flies that emerged during warm winter days. All fruit on the periphery of the release area was sprayed periodically (5 applications), as was the major fruit-growing areas within the region but outside the test zone, to minimize the possibility of fertile flies entering the release area. Daily from March to November, ca. 1,000,000 sterile flies were released. Trap catches indicated that the suppression obtained was about equal to that obtained using poison bait sprays. The early preferred host crops had no or negligible infestation (loquats, apricots, early peaches, and figs). The infestation of preferred summer fruits (peaches and figs) was reduced but not controlled. Less susceptible summer fruits were seldom infested. The estimated population was ca. 82.3 percent lower than in the previous year when no releases were made. Isolation and sterile fly distribution was inadequate to completely suppress the Mediterranean fruit fly population. (U.S.)

    The carob moth, Ectomyelois ceratoniae Zeller is abundant in the Mediterranean countries. It attacks various dry fruit in cultures or in stored products, notably pomegranate, Punica granatum L.; date palm, Phoenis dactylifera L. plantations; citrus, Citrus spp., apricot, Prunus armeniaca L. and pistachios, Pistachio vera. We can find E. ceratoniae in the north as well as in the south of Tunisia, especially in central zones and Saharan areas where caterpillar infestations can reach 90% of pomegranate fruit and 20% of dates (Dhouibi 1991). To reduce this damage, several control methods have been experimented. Chemical control is the most effective means of control against pests. However, against this species, insecticides seem to be difficult and randomly used, due to the endophytic behaviour of the pyralid and the position of the fruit on the pomegranate tree. Moreover, this method has very ominous repercussions on biological cadence. Besides, it is necessary to look for other control means to allow the preservation of the ecosystem. In Tunisia, several efforts have been directed at biological control, by using local parasitoids and through usage of the bio-insecticides mainly Bacillus thuringiensis (Dhouibi 1992, 1994, Dhouibi and Jemmasi 1993). In order to substitute the chemical control and to strengthen the integrated control, other possibilities can be envisaged, for example, the genetic method or the autocidal control, that is, based on mass rearing and the substerile male releases into the natural population. For the purpose, it provokes the sterility to ulterior generations and evaluates the impact of irradiation on the different biological parameters of emerged adults from treated nymphs and their competitiveness. Dhouibi and Omran (1995) and Dhouibi and Tijani (1996) have studied the mass rearing of the carob moth pyralid on an artificial diet and the effect of different irradiation doses, especially a substerilising dose, on E. ceratoniae pupae

    The experience of menopause can vary strongly from one society to another: frequency of hot flushes, other somatic and psychological symptoms, and changes in family and social relations. Several studies have shown that country of residence, country of birth, ethnicity, and social class all play roles in these variations. But few comparative anthropological studies have analysed the social processes that construct the experience of menopause or considered menopausal women's social and financial autonomy. To study the impact of the social status accorded to menopausal women and their social resources, during 2007 and 2008 we conducted a series of 75 in-depth interviews with women in different sociocultural settings: Tunisian women in Tunisia, Tunisian women in France, and French women in France, all aged from 45 to 70 years. Our methodological approach to the data included content analysis, typology development and socio-demographic analysis. Quite substantial differences appeared, as a function of social class and cultural environment. We identified three principal experiences of menopause. Tunisian working class women, in Tunisia and France, experience menopause with intense symptoms and strong feelings of social degradation. Among Tunisian middle-class women in both countries, menopause was most often accompanied by a severe decline in aesthetic and social value but few symptoms. For most of the French women, menopause involved few symptoms and little change in their social value. The distribution of types of experiences according to social but not geographic or national factors indicates that, in the populations studied here, the differences in symptoms are not biologically determined. Different experiences of menopause are linked to social class and to the degree of male domination. A given level of independence and emancipation allows women an identity beyond their reproductive function and a status unimpaired by menopause. Copyright © 2012 Elsevier Ltd. All

    Aims of this paper are to propose a geodynamic and sequential framework for the late Triassic and early Jurassic of and south Tunisia and to evidence the impact of local tectonics on the stratigraphic architecture. Facies of the Upper Triassic to Lower Jurassic of Southern Tunisia have been interpreted in terms of depositional environments. A sequential framework and correlation schemes are proposed for outcrops and subsurface transects. Nineteen middle frequency sequences inserted in three and a half low frequency transgression/regression cycles were evidenced. Despite some datation uncertainties and the unknown durations of Lower Jurassic cycles, middle frequency sequences appear to be controlled by eustasy. In contrast the tectonics acted as an important control on low frequency cycles. The Carnian flooding was certainly favored by the last stages of a rifting episode which started during the Permian. The regression accompanied by the formation of stacked angular unconformities and the deposition of lowstand deposits during the late Carnian and Norian occured during the uplift and tilting of the northern basin margins. The transpressional activity of the Jeffara fault system generated the uplift of the Tebaga of Medenine high from the late Carnian and led to the Rhaetian regional angular Sidi Stout Unconformity. Facies analysis and well-log correlations permitted to evidence that Rhaetian to Lower Jurassic Messaoudi dolomites correspond to brecciated dolomites present on the Sidi Stout unconformity in the North Dahar area. The Early-cimmerian compressional event is a possible origin for the global uplift of the northern African margin and Western Europe during the late Carnian and the Norian. During the Rhaetian and the early Jurassic a new episode of normal faulting occured during the third low frequency flooding. This tectonosedimentary evolution ranges within the general geodynamic framework of the north Gondwana margin controlled by the opening of both

    Full Text Available Septoria leaf blotch (SLB, caused by Zymoseptoria tritici (Desm. Quaedvlieg & Crous, 2011 (teleomorph: Mycosphaerella graminicola (Fuckel J. Schrot., is an important wheat disease in the Mediterranean region. In Tunisia, SLB has become a major disease of durum wheat (Triticum turgidum L. subsp. durum [Desf.] Husn. particularly during favorable growing seasons where significant yield losses and increase of fungicides use were recorded over the last three decades. The objectives of this study were to evaluate the effect of SLB severity on grain yield of new elite durum wheat breeding lines and to measure the relative effect of fungicide control on grain yield. Experiments were conducted during 2007-2008 and 2008-2009 cropping seasons. A set of 800 breeding lines were screened for reaction to SLB under natural infection at Beja research station. To estimate the disease effect, correlation between disease severity at early grain filling stage and grain yield was performed. Results showed that susceptible varieties yield was significantly reduced by SLB. Average yield reduction was as high as 384 and 325 kg ha-1 for every increment in disease severity on a 0-9 scale in both seasons, respectively. A negative correlation coefficient varied between -0.61 and -0.66 in both seasons. Treated and untreated trials conducted during 2008-2009 and 2009-2010 showed that yield of treated plots increased by 50% on the commonly cultivated susceptible varieties. The results of this investigation suggested that septoria incidence is related to large grain yield losses particularly on susceptible high yielding cultivars. However, appropriate fungicide application at booting growth stage could be beneficial for farmers. The development and use of more effective fungicide could be sought to alleviate the disease effects and therefore could be considered as a part of the integrated pest management and responsible use strategy on septoria leaf blotch in Tunisia.

    This paper employs the autoregressive distributed lag (ARDL) bounds methodological approach to investigate the relationship between economic growth, combustible renewables and waste consumption, carbon dioxide (CO2) emissions, and international tourism for the case of Tunisia spanning the period 1990-2010. The results from the Fisher statistic of both the Wald test and the Johansen test confirm the presence of a long-run relationship among the variables under investigation. The stability of estimated parameters has been tested, while Granger causality tests recommend a short-run unidirectional causality running from economic growth and combustible renewables and waste consumption to CO2 emissions, a bidirectional causality between economic growth and combustible renewables and waste consumption and unidirectional causality running from economic growth and combustible renewables and waste consumption to international tourism. In the long-run, the error correction terms confirm the presence of bidirectional causality relationships between economic growth, CO2 emissions, combustible renewables and waste consumption, and international tourism. Our long-run estimates show that combustible renewables and waste consumption increases international tourism, and both renewables and waste consumption and international tourism increase CO2 emissions and output. We recommend that (i) Tunisia should use more combustible renewables and waste energy as this eliminates wastes from touristic zones and increases the number of tourist arrivals, leading to economic growth, and (ii) a fraction of this economic growth generated by the increase in combustible renewables and waste consumption should be invested in clean renewable energy production (i.e., solar, wind, geothermal) and energy efficiency projects.

    Staphylococcus intermedius group (SIG) bacteria can colonise the nares of some animals but are also emerging pathogens in humans and animals. To analyse SIG nasal carriage in healthy donkeys destined for food consumption in Tunisia and to characterise recovered isolates. Nasal swabs from 100 healthy donkeys were tested for SIG recovery, and isolates were identified by biochemical and molecular methods. Antimicrobial susceptibility of isolates was tested and detection of antimicrobial resistance and virulence genes was performed. Isolates were typed at the clonal level by multilocus sequence typing and SmaI pulsed-field gel electrophoresis. Staphylococcus delphini and Staphylococcus pseudintermedius (included in SIG) were obtained in 19% and 2% of the tested samples, respectively, and one isolate per sample was characterised. All isolates were meticillin susceptible and mecA negative. Most S. delphini and S. pseudintermedius isolates showed susceptibility to all antimicrobials tested, with the exception of 2 isolates resistant to tetracycline (tet(M) gene) or fusidic acid. The following toxin genes were identified (percentage of isolates): lukS-I (100%), lukF-I (9.5%), siet (100%), se-int (90%), seccanine (19%) and expA (9.5%). Thirteen different pulsed-field gel electrophoresis profiles were identified among the 21 SIG isolates. Additionally, the following 9 different sequence types (STs) were detected by multilocus sequence typing, 6 of them new: ST219 (6 isolates), ST12 (5 isolates), ST220 (3 isolates), ST13, ST50, ST193, ST196, ST218 and ST221 (one isolate each). Staphylococcus delphini and S. pseudintermedius are common nasal colonisers of donkeys, generally susceptible to the antimicrobials tested; nevertheless, these SIG isolates contain virulence genes, including the recently described exfoliative gene (expA) and several enterotoxin genes, with potential implications for public health. This is the first description of S. delphini in Tunisia. The

    Rickettsioses are important remerging vector born infections. In Tunisia, many species have been described in humans and vectors. Genotyping is important for tracking pathogen movement between hosts and vectors. In this study, we characterized Rickettsia species detected in patients and vectors using multispacer typing (MST), proposed by Founier et al. and based on three intergenic spacers (dksA-xerC, rmpE- tRNA(fMet), mppA-pruC) sequencing. Our study included 25 patients hospitalized during 2009. Ticks and fleas were collected in the vicinity of confirmed cases. Serology was performed on serum samples by microimmunofluorescence using Rickettsia conorii and Rickettsia typhi antigens. To detect and identify Rickettsia species, PCR targeting ompA, ompB and gltA genes followed by sequencing was performed on 18 obtained skin biopsies and on all collected vectors. Rickettsia positive samples were further characterized using primers targeting three intergenic spacers (dksA-xerC, rmpE- tRNA(fMet) and mppA-purC). A rickettsial infection was confirmed in 15 cases (60%). Serology was positive in 13 cases (52%). PCR detected Rickettsia DNA in four biopsies (16%) allowing the identification of R. conorii subsp israelensis in three cases and R. conorii subsp conorii in one case. Among 380 collected ticks, nine presented positive PCR (2.4%) allowing the identification of six R. conorii subsp israelensis, two R. massiliae and one R. conorii subsp conorii. Among 322 collected fleas, only one was positive for R. felis. R. conorii subsp israelensis strains detected in humans and vectors clustered together and showed a new MST genotype. Similarly, R. conorii subsp conorii strains detected in a skin biopsy and a tick were genetically related and presented a new MST genotype. New Rickettsia spotted fever strain genotypes were found in Tunisia. Isolates detected in humans and vectors were genetically homogenous despite location differences in their original isolation suggesting

    In order to fight digestive parasitism in Tunisia, a national program of surveillance of non-permanent resident students in Tunisia has been found to detect these parasitosis in this target population. To determine the prevalence of intestinal parasitosis among non-permanent resident students in Tunisia, to identify the different parasitic species founded and to show the interest of this screening. During a period of 23 years (1990-2012), 7386 parasitological examinations of stools has been made among students essentially from or had visited tropical Africa, Maghreb and Middle-East, at the laboratory of Parasitology-Mycology at the Rabta Hospital of Tunis. The prevalence of intestinal parasitism found was 34.45% (i.e. 2545 infested students). Among the protozoa that have been isolated in the majority of cases (78.75%), amoebae were most frequently found (86.4%) represented mainly by Entamoeba coli and Endolimax nanus in respectively, 25.62 and 23.33% of parasites isolated; while Entamoeba histolytica/dispar, only pathogenic Amoeba was found in 8.05% of the total of parasites isolated. Regarding helminths, found in 21.25% of parasites isolated, Ankylostome was predominant (34.5%) represented by the species of Necator americanus. A single case of Ancylostom duodenale has been isolated. Among the identified parasite species, 38.7% were known parasitic pathogens for humans. These results note the interest of the control of the non-permanent resident students in Tunisia. The precocious tracking and treatment of affected subjects permits to avoid the introduction and the dissemination of parasites already rare and virulent strains in our country.

    To assess the effectiveness of a 3-year workplace-based intervention program on the control of the main noncommunicable disease risk factors (poor nutrition, physical inactivity, and tobacco use) among the employees of Sousse, Tunisia. We conducted a quasi-experimental study (pre- and postassessments with intervention and control groups) in six companies of the governorate of Sousse in Tunisia.The intervention program consisted of health education programs (eg, workshops, films and open sensitization days). We also scheduled free physical activity sessions and free smoking cessation consultations. Our intervention program showed meaningful improvement among the employees toward dietary and physical activity behaviors but not for tobacco use. Workplace is a crucial setting for health promotion, and future programs should consider a multisectoral approach to control the main noncommunicable disease risk factors.

    Water resource issues constitute a major concern in arid and semiarid areas in Tunisia. To meet rising demand for different human activities considerable importance is being given to improving the natural groundwater recharge by the installation of hydraulic catchments. In central Tunisia, numerous retention sites and dams have been built since 1990, for example, the el Ogla dam in the Nadhour-Saouaf basin. In order to determine the implication of these hill reservoirs on the hydrodynamic functioning and water quality of the aquifer system, hydrochemical (major elements) and isotopic methods have been employed. The interpretation of these results showed that the shallow aquifer is recharged mainly by surface water and water dam infiltration from the el Ogla and Sahel catchments. A tentative isotopic mass balance based on stable isotope contents leads to the quantification of the artificial recharge rate, which ranges between 42% and 86% of precipitation in the humid period.

    The aim of this paper is to examine the causal relationship between CO2 emissions, real GDP, energy consumption, financial development, trade openness, and urbanization in Tunisia over the period of 1971-2012. The long-run relationship is investigated by the auto-regressive distributed lag (ARDL) bounds testing approach to cointegration and error correction method (ECM). The results of the analysis reveal a positive sign for the coefficient of financial development, suggesting that the financial development in Tunisia has taken place at the expense of environmental pollution. The Tunisian case also shows a positive monotonic relationship between real GDP and CO2 emissions. This means that the results do not support the validity of environmental Kuznets curve (EKC) hypothesis. In addition, the paper explores causal relationship between the variables by using Granger causality models and it concludes that financial development plays a vital role in the Tunisian economy.

    To investigate the level of genetic differentiation and diversity among Pyrenophora teres isolate populations originating from different agro-ecological areas of Syria and Tunisia and to determine the potential of AFLP profiling in genotyping Pyrenophora teres f. teres. In this study, AFLP markers have been employed to identify patterns of population structure in 20 Pyrenophora teres f. teres populations from Syria and Tunisia. Ninety-four isolates were studied by the use of a protocol that involved stringent PCR amplification of fragments derived from digestion of genomic DNA with restriction enzymes EcoRI and MesI. Based on 401 amplified polymorphic DNA markers (AFLP), variance analyses indicated that most of the variation was partitioned within rather than between populations. Genotypic diversity (GD) was high for populations from Rihane, local landraces and different agro-ecological zones (GD = 0·75-0·86). There was high genetic differentiation among pathogen populations from different host populations in Syria (Gst  = 0·31, ht = 0·190) and Tunisia (Gst  = 0·39, ht = 0·263), which may be partly explained by the low gene flow around the areas sampled. A phenetic tree revealed three groups with high bootstrap values (55, 68, 76) and reflected the grouping of isolates based on host, or agro-ecological areas. AFLP profiling is an effective method for typing the genetically diverse pathogen Pyrenophora teres f. teres. The study represents a comparative analysis of the genetic diversity in P. teres isolates from two countries spanning two continents and also shows that several distinct P. teres genotypes may be found in a given environment. The implications of these findings for Pyrenophora teres f. teres evolutionary potential and net blotch-resistance breeding in Syria and Tunisia were also discussed. © 2012 The Society for Applied Microbiology.

    Full Text Available BACKGROUND: In northern Tunisia, the co-circulation of two related sand fly-borne phleboviruses, Toscana virus (TOSV and Punique virus (PUNV was previously demonstrated. In contrast to TOSV, a prominent human pathogen, there is no data supporting that PUNV is capable to infect and cause disease to humans. We studied the respective involvement of TOSV and PUNV in human infections in northern Tunisia through a seroprevalence study. METHODS: The presence of TOSV and PUNV neutralising antibodies (NT-Ab was tested in human sera collected from 5 districts of the governorate of Bizerte, and the titres of NT-Ab were estimated by microneutralisation (MN assay. PRINCIPAL FINDINGS: A total of 1,273 sera were processed. TOSV and PUNV NT-Ab were detected in 522 (41% and 111 sera (8.72% respectively. TOSV seroprevalence varied from 17.2% to 59.4% depending on the district. Analysis of TOSV geometric mean titre values demonstrated a constant increase according to the age. The vast majority of sera containing NT-Ab were found to be more reactive toward TOSV than PUNV. Indeed, past infections with PUNV and TOSV were undisputable for 5 and 414 sera, respectively. CONCLUSIONS: PUNV may be capable to infect humans but at a low rate. TOSV is responsible for the vast majority of human infections by sand fly-borne phleboviruses in northern Tunisia. TOSV must be considered by physician and tested in diagnostic laboratories for patients with meningitis and unexplained fever in northern Tunisia.

    Full Text Available Damage caused by Diplodia pinea on Pinus pinaster and P. radiata forests are reported for the fi rst time in Tunisia. The affected plants show shoot blight, canker and branch dieback. On decaying and dead branches pycnidia of D. pinea are observed. The fungus was repeatedly isolated from the bark of symptomatic branches. The results of pathogenicity tests confirm the virulence of D. pinea and the susceptibility of both Pinus species to infection.

    In Tunisia, the epidemiological situation of leishmaniasis is characterized by the coexistence in a rather circumscribed territory (165000 km2, including the Sahara) of 4 forms of leishmaniasis caused by 3 species: Leishmania infantum, Leishmania major and Leishmania tropica (L. tropica) (synonymous Leishmania killicki). One of the factors determining the clinical, epidemiological and immunological diversity of leishmanioses is certainly the existence of a vector-parasite specificity of of...

    Full Text Available A total of 118 sera were collected during 2016 from two groups of dromedaries from Kebili and Medenine governorates in the south of Tunisia. The aim of this study was to provide the first serological investigation of four emerging vector-borne diseases in two groups of dromedaries in Tunisia. Sera were tested by ELISA and serum neutralisation test to identify West Nile virus (WNV, bluetongue virus (BTV, epizootic haemorrhagic disease virus (EHDV and Rift Valley fever virus (RVFV. In the first group, the seroprevalence for BTV was 4.6%, while in the second group, it was 25.8% for WNV and 9.7% for BTV. Only serotype 1 was detected for BTV in the two groups. No evidence for circulation of RVF and EHD viruses was revealed. Results indicated that dromedaries can be infected with BTV and WNV, suggesting that this species might play a significant role in the epizootiology of these viral diseases in Tunisia and neighbouring countries.

    Intestinal parasitosis are cosmopolitan affections, often related to the fecal peril. However urinary bilharziosis is a disease eliminated in Tunisia. As part of monitoring the emergence and re-emergence of intestinal parasitosis and urinary bilharziasis, foreign students benefit from parasitological systematic monitoring stool and urine during their enrollment to the University. To study the prevalence of various intestinal parasitosis and urinary bilharziasis among non permanent resident students in Tunisia. A retrospective survey was carried at the Laboratory of Parasitology- Mycology of Charles Nicolle Hospital of Tunis during the inscription period of 6 university years 2005-2010. 328 students profited from a parasitological examination of stool and urine. 144 students (43.9%) harbored intestinal parasites. More than one parasite was detected in 69 students (47.9%). Intestinal protozoa were the majority of identified parasites (96.9%). 9.7% of identified parasites were pathogenic. Three cases (0.91%) of urinary bilharziasis were diagnosed. The prevalence of intestinal and urinary parasitism among the "non-permanent residents" students in Tunisia has not changed. This justifies a systematic parasitologic monitoring for students coming from areas of high endemicity of parasitosis in order to avoid the introduction of these.

    Northern Uganda has been devastated by more than 20 years of open conflict by the LRA (Lord's Resistance Army) and the Government of Uganda. This war has been marked by extreme violence against civilians, who had been gathered in protected IDP (Internally Displaced Persons) camps. At the height of the displacement in 2007, the UN office for coordination of humanitarian affairs, estimated that nearly 2.5 million people were interned into approximately 220 camps throughout Northern Uganda. With the improved security since mid-2006, the people displaced by the conflict in Northern Uganda started to move out of the overcrowded camps and return either to their villages/parishes of origin or to resettlement/transit sites. However, basic water, sanitation and hygiene infrastructure in the return areas or any new settlements sites are minimal. People returning to their villages of origin encounter a situation where in many cases there is no access to safe water. Since 1998 ACF (Action Against Hunger, part of the Action Contre la Faim International Network) activities have been concentrated in the Acholi and Lango regions of Northern Uganda. ACF's WASH (Water, sanitation and hygiene) department interventions concern sanitation infrastructure, hygiene education and promotion as well as water points implementation. To ensure safe water access, actions are focused in borehole construction and traditional spring rehabilitation, also called "protected" springs. These activities follow the guidelines as set forth by the international WASH cluster, led by UNICEF. A three year project (2008-2010) is being implemented by ACF, to monitor the available groundwater resources in Northern Uganda. The main objectives are: 1. to monitor the groundwater quality from existing water points during different hydrological seasons, 2. to identify, if any, potential risks of contamination from population concentrations and displacement, lack of basic infrastructure and land use, and finally 3. to

    Radioactive materials refer to any materials that spontaneously emit ionizing radiation and of which the radioactivity per gram is greater than 0.002 micro-curie. They include: spent nuclear fuel, nuclear wastes, medical sources i.e. Co-60, industrial sources i.e. Cs-137, Am-241:Be, Ra-226, and sources for research. In view of the rising reported cancer cases in Uganda, which might be as a result of radiation exposure due to constant transportation of radioactive materials i.e. industrial sources, a risk analysis was thought of and undertaken for the country's safety evaluation and improvement. It was therefore important to undertake a risk assessment of the actual and potential radiation exposure during the transportation process. This paper explains a study undertaken for transport risk assessment of the impact on the environment and the people living in it, from exposure to radioactivity during transportation of the industrial sources in Uganda. It provides estimates of radiological risks associated with visualized transport scenarios for the highway transport mode. This is done by calculating the human health impact and radiological risk from transportation of the sources along Busia transport route to Hoima. Busia is the entry port for the sources whilst Hoima, where various industrial practices that utilize sources like oil explorations are centered. During the study, a computer code RADTRAN-6 was used. The overall collective dose for population and package transport crew are 3.72E-4 and 1.69E-4 person-sievert respectively. These are less than the exemption value recommended by the IAEA and Uganda Regulatory Authority for public implying that no health effects like cancer are to be expected. Hence the rising cancer cases in the country are not as a result of increased transportation of radioactive materials in the Industrial sector

    We conducted 16 in-depth interviews with family caregivers of AIDS patients in three rural districts in western Uganda. They were selected from a client visitation list of the home-based care program for AIDS patients, based on volunteer participation. Family caregivers reported huge problems associated with providing the necessary psychological, social, and economic care. They also said that the physical and emotional demands of caregiving are overwhelming daily challenges. Most support to AIDS patients provided by family, friends, and the churches. The study highlights the great burden of caregivers, in sub-Saharan Africa who most often are elderly women and young girls. This study examine, the burden and related health issues of family caregivers, primarily women, for AIDS patients in Uganda. It was part of a broad research project using qualitative methods on family caregiving in the home environment in sub-Saharan Africa. As the requirements for family care giving are often overwhelming for women under the conditions as they exist in Uganda and in other developing countries, it constitutes a gender issue of great importance that has not been appreciated fully in the international literature. Family caregiving is also of international relevance, as HIV/AIDS is a global pandemic of previously unknown proportions. In many poor countries, family caregiving is the most common and often the only care that AIDS patients receive, because clinic-based care often is not available close to home or is not affordable. Therefore, family caregiver support programs to alleviate this burden are essential for all those countries where HIV/AIDS is prevalent. Family caregiver burden encompasses medical, social, and economic issues at the household level, which requires an interdisciplinary approach in order to fully understand and appreciate the different dimensions of the family caregiver burden and its negative impact on the lives of so many women in so many countries.

  7. African Indigenous science in higher education in Uganda

    Akena Adyanga, Francis

    This study examines African Indigenous Science (AIS) in higher education in Uganda. To achieve this, I use anticolonial theory and Indigenous knowledge discursive frameworks to situate the subjugation of Indigenous science from the education system within a colonial historical context. These theories allow for a critical examination of the intersection of power relations rooted in the politics of knowledge production, validation, and dissemination, and how this process has become a systemic and complex method of subjugating one knowledge system over the other. I also employ qualitative and autoethnographic research methodologies. Using a qualitative research method, I interviewed 10 students and 10 professors from two universities in Uganda. My research was guided by the following key questions: What is African Indigenous Science? What methodology would help us to indigenize science education in Uganda? How can we work with Indigenous knowledge and anticolonial theoretical discursive frameworks to understand and challenge the dominance of Eurocentric knowledge in mainstream education? My research findings revealed that AIS can be defined in multiple ways, in other words, there is no universal definition of AIS. However, there were some common elements that my participants talked about such as: (a) knowledge by Indigenous communities developed over a long period of time through a trial and error approach to respond to the social, economic and political challenges of their society. The science practices are generational and synergistic with other disciplines such as history, spirituality, sociology, anthropology, geography, and trade among others, (b) a cumulative practice of the use, interactions with and of biotic and abiotic organism in everyday life for the continued existence of a community in its' totality. The research findings also indicate that Indigenous science is largely lacking from Uganda's education curriculum because of the influence of colonial and

    Bacillus cereus group is widespread in nature and foods. Several members of this group are recognized as causing food spoilage and/or health issues. This study was designed to determine the prevalence and genetic diversity of the B. cereus group strains isolated in Tunisia from different foods (cereals, spices, cooked food, fresh-cut vegetables, raw and cooked poultry meats, seafood, canned, pastry, and dairy products). In total, 687 different samples were collected and searched for the presence of the B. cereus group after selective plating on MYP agar and enumeration of each sample. The typical pink-orange uniform colonies surrounded by a zone of precipitate were assumed to belong to the B. cereus group. One typical colony from each sample was subcultured and preserved as cryoculture. Overall, 191 (27.8%) food samples were found positive, giving rise to a collection of 191 B. cereus -like isolates. The concentration of B. cereus -like bacteria were below 10 3 cfu/g or ml in 77.5% of the tested samples. Higher counts (>10 4 cfu/g or ml) were found in 6.8% of samples including fresh-cut vegetables, cooked foods, cereals, and pastry products. To verify whether B. cereus -like isolates belonged to the B. cereus group, a PCR test targeting the sspE gene sequence specific of the group was carried out. Therefore, 174 isolates were found to be positive. Food samples were contaminated as follows: cereals (67.6%), pastry products (46.2%), cooked food (40.8%), cooked poultry meat (32.7%), seafood products (32.3%), spices (28.8%), canned products (16.7%), raw poultry meat (9.4%), fresh-cut vegetables (5.0%), and dairy products (4.8%). The 174 B. cereus isolates were characterized by partial sequencing of the panC gene, using a Sym'Previous software tool to assign them to different phylogenetic groups. Strains were distributed as follows: 61.3, 29.5, 7.5, and 1.7% in the group III, IV, II, and V, respectively. The genetic diversity was further assessed by ERIC-PCR and PFGE

    Groundwater is the most important source of water supply in southern Tunisia. Previous hydrogeologic and isotopic studies carried out in this region revealed the existence of two major aquifer systems: the “Complex Terminal” (CT) and the “Continental Intercalaire” (CI). Turonian carbonates constitute one of the major aquifer levels of the CT multilayered aquifer. It extends over most of southern Tunisia, and its hydrodynamic regime is largely influenced by tectonics, lithology and recharge conditions. Forty-eight groundwater samples from the CI and Turonian aquifers were collected between January and April 2004 for chemical and isotopic analyses. Hydrochemistry and isotopic tools were combined to get an insight into the processes controlling chemical composition of groundwater and wide-scale interaction of these two aquifer systems. Analysis of the dissolved constituents revealed that several processes control the observed chemical composition: (i) incongruent dissolution of carbonate minerals, (ii) dissolution of evaporitic minerals, and (iii) cation exchange. Dissolution alone cannot account for the observed high supersaturation states of groundwater with respect to calcite and dolomite. The observed supersaturation is most probably linked to geogenic CO 2 entering water-bearing horizons of the CT and CI aquifers via deep tectonic faults and discontinuities and subsequent degassing in the exploitation wells. Presence of geogenic CO 2 in the investigated region was confirmed by C isotope data of the DIC reservoir. The radiocarbon content of the Turonian samples varied between 9.5 and 43 pmc. For CI samples generally lower values were recorded, between 3.8 and 22.5 pmc. Stable isotope composition of Turonian groundwater samples varied from −8.3 to −5.3‰ for δ 18 O and from −60 to −25‰ for δ 2 H. The corresponding ranges of δ values for the Continental Intercalaire samples were from −8.9‰ to −6.9‰ for δ 18 O and from −68.2‰ to

    Full Text Available This study aimed to identify a broad spectrum of respiratory pathogens from hospitalized and not-preselected children with acute respiratory tract infections in the Farhat Hached University-hospital of Sousse, Tunisia. Between September 2013 and December 2014, samples from 372 children aged between 1 month and 5 years were collected, and tested using multiplex real-time RT-PCR by a commercial assay for 21 respiratory pathogens. In addition, samples were screened for the presence of Streptococcus pneumoniae 16S rDNA using real-time PCR. The viral distribution and its association with clinical symptoms were statistically analyzed. Viral pathogens were detected in 342 (91.93% of the samples of which 28.76% were single positive and 63.17% had multiple infections. The most frequent detected viruses were rhinovirus (55.64%, respiratory syncytial virus A/B (33.06%, adenovirus (25.00%, coronavirus NL63, HKU1, OC43, and 229E (21.50%, and metapneumovirus A/B (16.12%. Children in the youngest age group (1-3 months exhibited the highest frequencies of infection. Related to their frequency of detection, RSV A/B was the most associated pathogen with patient's demographic situation and clinical manifestations (p<0.05. Parainfluenza virus 1-4 and parechovirus were found to increase the risk of death (p<0.05. Adenovirus was statistically associated to the manifestation of gastroenteritis (p = 0.004.

    A sedimentological and mineralogical study of sedimentary cores allowed reconstructing the evolution of depositional environments along the Northern coast of Sfax (Tunisia). The aim of this research work is to identify the factors controlling the sedimentation from the Holocene to the Present time. Three 30-m sediment cores collected by drilling at 30 m water depth were analyzed for their color, magnetic susceptibility signal, grain size by laser diffraction, organic matter content by loss of ignition, carbonate content by calcimetry and mineralogy by X-ray diffraction on bulk powder and clay <2 μm. They broadly present the same sedimentological and mineralogical features. Microscopical observations of petrographic slides allowed identifying six main sedimentary facies. Bulk mineralogical assemblages comprised clay minerals, quartz, calcite, gypsum and K-feldspars were examined. Considerable change was observed in the carbonate content that mimicked the bioclaste abundance and diluted the detrital minerals (clay minerals, quartz and feldspars). The gypsum mainly occurred in the lower sedimentary columns (SC12 and SC9) and in the upper/middle of core SC6. The clay fraction was made of a mixture of kaolinite, illite, smectite and palygorskite with no clear variation through core depth. Both grain-size parameters and magnetic susceptibility profile showed a sharp transition in the upper 2-5 m of the sedimentological columns. Coarse, sandy to gravely sediments characterized by a low magnetic susceptibility signal were replaced by fine bioclastic-rich clayey sediments. The analysis of vertical succession of depositional facies revealed a fluvial depositional environment (coastal plain) basically marked by fluvial channels and inundation plains at the bottom of all cores. However, core-top sediments recorded a littoral marine environment with sand depositions rich in gastropods, lamellibranches and algæ. Depositional facies, sedimentological and mineralogical

    The total installed electricity capacity is 595.8 MW mainly hydropower, cogeneration from biomass and thermal power. The Installed Capacity is expected to rise to about 802 MW in 2011 with commissioning of Bujagali hydropower Plant currently under construction, and other mini hydropower plants. Current contribution to the Energy Supply Pattern: Electricity 1.1%, Oil products 9.5% and Biomass 89.4%. (Uganda Energy balance, 2009). The need to drift from use of Biomass as source of energy prompted the consideration of energy supply options which are environmentally friendly. This includes the energy efficiency campaigns, renewable energy technologies and NPP. Uganda government intends to substantially increase power generation capacity in the next 20 years of which nuclear will have significant contribution. Legal framework has been put in place and currently building of capacity through training of young scientists. Ministry of Energy and Mineral Development is the home of all the energy Sector programmes including the nuclear Energy Programme. The Atomic Energy Act 2008 has been promulgated and the Atomic Energy Council was established to regulate the peaceful application of Atomic energy. The Council is mandated to provide protection and safety of individuals, society and the environment from the dangers resulting from ionizing radiation

    Research purpose: The purpose of this article was to review the need for appropriate employer-employee relationships that will ensure quality services and service delivery in public universities in Uganda. Motivation for the study: The researchers set out to examine why managers of public universities in Uganda were continuously paying less attention to the needs of the employees. Research design, approach and method: A descriptive research design was employed and 12 respondents, purposively selected from 4 public universities, were interviewed. Data were recorded, transcribed and analysed using Nvivo software. This article is based on the perspective of agency theory, and discussed the contractual relationship between management and employees. The agency theory was deemed necessary because of its contribution to organisational literature. Main findings: There is a need to create and nurture a collegial working climate that promotes quality interactions through information sharing. This results in creating and retaining motivated and committed employees, and also helps to overcome the paradox of balancing the high demand for university education whilst offering quality services. Practical/managerial implications: Managers have to continuously monitor and accommodate employee needs and demands. Contribution/value-add: The potential value of the paper is its function as a guide for public universities to have visionary managers that will introduce new approaches to managing public universities in a competitive global environment.

    An ethical review committee consisting of medical scientists, social scientists, and lawyers has been established by the Ugandan government to oversee individuals and institutions conducting biomedical research. The research of Professor Sali, who produced and marketed Mariandina as a cure for acquired immunodeficiency syndrome (AIDS), is not recognized, according to Dr. Jeremiah Twa-twa, Registrar of the National Medical Council. Professor Sali had been given six months to produce an acceptable protocol, with controls, that demonstrated the efficacy of the drug. He had stated previously that his patients received a minimum of six tablets daily of Mariandina A, B, or J; thousands are said to have been treated. Professor Sali, who returned to Uganda in 1990 with a 100,000-pound loan to produce the drug, advised his patients to sell everything they owned in order to pay for their treatment, according to Major Ruranga Rubaramira (head of a joint clinical council). The Uganda AIDS Commission is also considering the use of herbs in the treatment of AIDS; nine Western-trained researchers are collaborating with herbalists in studies that have shown promising results. Dr. Donna Kabatesi, who heads a clinic that uses both herbs and Western medicine in the treatment of AIDS patients at Mulago hospital, believes herbs are equally effective for some purposes.

Little attention has been given to how patients with T2D try to achieve treatment when the availability of public health care for their disease is limited, as is the case in most SSA countries. In this paper we focus on the landscape of availability of care and the therapeutic journeys of patients within that landscape. Based on fieldwork in south-western Uganda including 10 case studies, we explore the diabetes treatment options in the area and what it takes to access the available treatment. We analyse the resources patients need to use the available treatment options, and demonstrate that the patients' journeys to access and maintain treatment are facilitated by the knowledge and support of their therapy management groups. Patients access treatment more effectively, if they and their family have money, useful social relations, and knowledge, together with the capacity to communicate with health staff. Patients coming from households with high socio-economic status (SES) are more likely to have all of these resources, while for patients with low or medium SES, lack of economic resources increases the importance of connections within the health system.

    Uganda has embraced inclusive education and evidently committed itself to bringing about disability inclusion at every level of education. Both legal and non-legal frameworks have been adopted and arguably are in line with the intent of the Convention on the Rights of Persons with Disabilities (CRPD) on education. The CRPD, in Article 24, requires states to attain a right to education for persons with disabilities without discrimination and on the basis of equal opportunities at all levels of education. Despite Uganda's robust disability legal and policy framework on education, there is evidence of exclusion and discrimination of students with disabilities in the higher education institutions. The main objective of this article is to explore the status of disability inclusion in higher education and strategies for its realisation, using evidence from Emong's study, workshop proceedings where the authors facilitated and additional individual interviews with four students with disabilities by the authors. The results show that there are discrimination and exclusion tendencies in matters related to admissions, access to lectures, assessment and examinations, access to library services, halls of residence and other disability support services. The article recommends that institutional policies and guidelines on support services for students with disabilities and special needs in higher education be developed, data on students with disabilities collected to help planning, collaboration between Disabled Peoples Organisations (DPO's) strengthened to ensure disability inclusion and the establishment of disability support centres.

    Nodding Syndrome (NS) is a childhood neurological disorder characterized by atonic seizures, cognitive decline, school dropout, muscle weakness, thermal dysfunction, wasting and stunted growth. There are recent published information suggesting associations between Nodding Syndrome (NS) with cerebrospinal fluid (CSF) VGKC antibodies and serum leiomidin-1 antibody cross reacting with Onchocerca Volvulus ( OV ). These findings suggest a neuro-inflammatory cause of NS and they are important findings in the search for the cause of Nodding Syndrome. These observations perhaps provide further, the unique explanation for the association between Nodding Syndrome and Onchocerca Volvulus . Many clinical and epidemiological studies had shown a significant correlation between NS and infestation with a nematode, Onchocerca volvulus which causes a disease, Onchocerciasis , some of which when left untreated can develop visual defect ("River Blindness"). While these studies conducted in Northern Uganda and Southern Sudan indicate a statistically significant association with ( OV infection (using positive skin snips), we observe that ( OV is generally endemic in many parts of Sub Saharan Africa and Latin America and that to date, no NS cases have been recorded in those regions. This letter to the Editor is to provide additional information on the current view about the relationship between Nodding Syndrome and Onchocerca Volvulus as seen in Northern Uganda.

  19. Uganda--rehabilitation, or redefinition of health services?

    1986-01-01

    Uganda had one of the best health care delivery systems in Africa. The decade of misrule by Amin saw a collapse of the country and an exodus of doctors and other professions. The 1979 liberation war and subsequent political instability and insecurity further aggravated the poor health services then available. When political stability was temporarily restored in December 1980 the cash crop export sector took priority over social services and the health budget declined to only 3.5% compared to a former level of 7.5% of government budget. Emergencies in West Nile, Karamoja and the Luwero triangle continued to plague rehabilitation efforts upto 1985. Alternate strategies for improving health are proposed including female education, increased budget allocations, food and nutrition policy and health information. Uganda's prospect for rebuilding the health services has begun with immunization, control of diarrhoeal diseases, nutrition surveillance in Karamoja and an essential drugs programme, but the success of these is dependent upon political stability and improvement in overall security.

    Full Text Available Tree rings provide fruitful information on climate features driving annual forest growth through statistical correlations between annual tree growth and climate features. Indices built upon tree growth limitation by carbon sequestration (source hypothesis or drought-driven cambial phenology (sink hypothesis can be used to better identify underlying processes. We used both analytical frameworks on Quercus suber, a sparsely studied species due to tree ring methodological issues, and growing on a favorable sub-humid Mediterranean climate and deep soil conditions in Tunisia (North Africa. Statistical analysis revealed the major role of autumnal rainfall before the growing season on annual tree growth over the 1918–2008 time series. Using a water budget model, we were able to explain the critical role of the deep soil water refill during the wet season in affecting both the drought onset controlling growth phenology and the summer drought intensity affecting carbon assimilation. Analysis of recent climate changes in the region additionally illustrated an increase in temperatures enhancing the evaporative demand and advancing growth start, and a decline in rainfalls in autumn, two key variables driving stem growth. We concluded on the benefits of using process-based indices in dendrochronological analysis and identified the main vulnerability of this Mediterranean forest to autumnal rainfall decline, a peculiar aspect of climate change under summer-dry climates.

    To report the histological features of celiac disease in a paediatric population originating from south Tunisia. A retrospective study of a series of duodenal biopsies from 114 children with celiac disease diagnosed over a period of 6 years (from January 1999 to December 2004). The diagnosis was confirmed by histological results, serological studies and clinical response to gluten free diet. The average age of patients was of 6.2 years (range 6 months-15 years). Sex ratio was 0.71. Symptoms were dominated by chronic diarrhea (48%), weight loss (50%) and anemia (20.1%). Histological findings showed an intraepithelial lymphocytosis (Marsh type 1) in 12.2% of cases, type 2 was present in 1.7% of cases and type 3 (villous atrophy) in 86% of cases. A treatment with a gluten-free diet was indicated for all patients, only the cases who haven't presented a clinical amelioration (11 cases) have beneficed a control biopsie; a villous atrophy was persistent in 80% of this patients. Histological features in duodenal biopsies for the diagnosis and the follow-up of patients with coeliac disease. This allows an appropriate treatment and prevents further complications.

    2008-06-01

    This study investigated the presence and origin of hydrocarbon pollution in industrial waste water sediments found near the Jarzouna (Bizerte, Tunisia) oil refinery. Analyses of surface sediments (layer 1) and deep sediments (layer 2) showed that Total Hydrocarbon (TH) concentrations ranged from 602 +/- 7.638 microg/g in layer-1 to 1270 +/- 2.176 microg/g in layer-2. The results suggest that the deeper the sediment, the higher the level of total hydrocarbon found. The sedimentary Non Aromatic Hydrocarbon (NAH) and Aromatic Hydrocarbon (AH) concentrations ranged from 66.22 +/- 1.516 to 211.82 +/- 10.670 microg/g for NAH, and from 13.84 +/- 0.180 to 115.60 +/- 2.479 microg/g for AH. The high variability of these concentrations was associated with the location of the sediment collection sites. Aliphatic biomarker analysis revealed petroleum contamination close to the refinery rejection site, and biogenic sources further away. Petroleum contamination may be associated with increased industrial activity in the area of Jarzouna-Bizerte in the Mediterranean Sea.

  3. Hydrodynamic framework of Saharan Triassic aquifers in South Tunisia and Algeria

    Dhia, H. Ben; Chiarelli, A.

    The main characteristics of the lower Triassic in the Saharan part of Tunisia are presented. This first study of the aquifer is made possible because of data available from numerous petroleum wells that exist in the region. The results show that the reservoir is of importance for either geothermal energy recovering or human water needs; especially since its salinity lies in the range 2 g/l to 60 g/l. Along the Tunisian-Llibyan frontier, because of its pressure and salinity (<3 g/l), the aquifer can be used for regional needs. The study also shows that the salinity gradient (SE-NW) increases orthogonally to the runoff direction (SW-NE). This phenomenon was unexpected and it is necessary to consider the aquifer in its regional North African framework and to include its Algerian part to understand it; when the salinity and potentiometric maps include both countries, a regional pattern is evident. Furthermore, a correspondence is noted between the salinity variations and the percentage of detritic elements in the reservoir. Salinity increases toward the NW, while the detritic elements decrease in that direction. Zones with salt content lower than 5 g/l seem to be related to good reservoirs and shales, that are rich in sands, and carbonates. The aquifer water supply is primarily linked to gravity flow and secondarily to compaction flow.

    This study investigated the environmental quality of the Bizerte Lagoon (Tunisia) through an integrated approach that combined environmental, biogeochemical, and living benthic foraminiferal analyses. Specifically, we analyzed the physicochemical parameters of the water and sediment. The textural, mineralogical, and geochemical characteristics of the sediment, including total organic carbon, total nitrogen, simultaneously extracted metals (SEM), acid volatile sulfides (AVS), chlorophyll a, CaCO3, and changes in bacterial populations and carbon isotopes were measured. The SEM/AVS values indicated the presence of relatively high concentrations of toxic metals in only some areas. Foraminiferal assemblages were dominated by species such as A. parkinsoniana (20–91%), Bolivina striatula (coastal lagoons both in Mediterranean and northeast Atlantic regions. The results of this work suggest that Bizerte Lagoon is a unique setting. This lagoon is populated by typical marine species that invaded this ecosystem, attracted not only by the prevailing favorable environmental conditions but also by the abundance and quality of food. The results indicate that the metal pollution found in some areas have a negative impact on the assemblages of foraminifera. At present, however, this negative impact is not highly alarming.

    Full Text Available Since the establishment of the ‘Tunisian Chemical Group’ in Gabes city, Tunisia, no serious investigations were carried out about the heavy metal pollution in Gabes gulf.  In the present study, the contents of four heavy metals were assessed in four mollusk species (two gastropods, Gibbula ardens and Patella caerulea, and two bivalves, Pinctada radiata and Pinna nobilis, collected from twelve coastal stations. The results obtained showed generally that high concentrations of heavy metals were recorded in the central area of Gabes gulf, nearer to Gabes city; the low concentrations were in contrast found at the edges of this gulf, which is probably due to the chemical pollution generated from the huge industry of phosphoric acid in Gabes city. Comparing the results found with the four examined species, the lowest concentrations were noted with the two bivalve species P. radiata and P. nobilis. The highest heavy metals’ concentrations, noted during this study, are comparable to the findings of other authors in other areas, but they are considerably beyond the standards. A remediation action is necessarily needed either by reducing the amount of heavy metals in the phosphgypums quantities thrown directly in the sea or by stopping completely this harmful industry to protect the marine life in the area. A remediation action is necessarily needed to protect the marine life in the area.

    Full Text Available The distribution and life cycle of wild radish (Raphanus raphanistrum L. and a survey of the pathogens of this plant are reported for the northern regions of Tunisia. Wild radish is a common weed of cereal crops and legumes. It germinates in early autumn (October, develops a rosette stage in November to December after which stem growth, fl owering and pod production occur through to May, with pod maturity completed in June. Fungus isolation from the foliar tissues exhibiting disease symptoms showed that wild radish was infected with the fungi Albugo candida, Alternaria spp. including A. brassicicola, and A. raphani, Erysiphe cruciferarum, Stemphylium herbarum, Peronospora parasitica and Phoma lingam. Ascochyta spp., Cercospora armoraciae, Cladosporium cladosporioides and Colletotrichum higginsianum are here reported from wild radish for the first time. Inoculation tests of pathogens on wild radish plants showed that the most injurious fungi were Alternaria raphani and Phoma lingam. The remaining pathogens were weakly to moderately aggressive on this weed. To access the pathogenic effect of fungi spontaneously infecting natural populations of wild radish, the weed was grown in a field experiment with and without the broad-spectrum systemic fungicide Carbendazim. Results showed a statistically significant two-fold decrease in the number and weight of seed pods in the non-treated plants, indicating that the reproductive potential of wild radish was naturally reduced by fungal infection. Foliar pathogenic fungi have a potential in the integrated weed management of wild radish, this role merits further investigations.

    Analyses of organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and butyl tins (BuSn) were conducted on sediments from Ichkeul Lake-Bizerte Lagoon watershed (Tunisia). A total of 59 compounds (16 PAHs, 12 PCBs, 22 OCPs and 9 BuSn) were measured in 40 surface sediment samples collected during two campaigns. High concentrations of total PAHs were identified in the lagoon ranging from 122 to 19600ng·g -1 . Several OCPs, including endrin, dieldrin, and lindane (Hexachlorocyclohexane or HCH or BHC) were found in high concentrations in Ichkeul Lake, ranging from 28 to 2012ngg -1 . PAHs and OCPs varied seasonally, in response to the complex hydrology of the watershed. The concentrations of total PCBs ranged between 0.04 and 10.653ngg -1 and suggests low total PCBs sediment contamination, when compared to most international criteria. Total BuSn concentrations range between 67 and 526ng·g -1 , which are relatively low when compared to most international criteria and ecological risk assessments. This is the first study of organic contamination in Ichkeul Lake (RAMSAR and UNESCO World Heritage site). Copyright © 2017 Elsevier Ltd. All rights reserved.

    The Complexe Terminal (CT) aquifer system is the main water supply for remote areas of southern Tunisia. Its exploitation has resulted in significant draw-down of the water table. The CT aquifer is a multilayered aquifer lodged in Miocene sand deposits, Senonian limestones and Turonian carbonates. Little is known about the relationships and exchanges between the different layers. Here, uranium isotopic measurements carried out in groundwater samples from the CT aquifer are presented in order to constrain models for mixing of water masses, water-rock interaction and groundwater flow. Analyses were performed using a VG54 (TIMS) at the CEREGE. Results indicate a range in {sup 238}U concentration and {sup 234}U/{sup 238}U activity ratios of 1.5 to 8 ppb and 1.1 to 3.2 respectively. Together with major and trace analyses, uranium isotopic compositions provide important insights into the factors controlling the chemical evolution of groundwater and shows very distinct patterns between carbonate and sandstone layers.

    Full Text Available Tunisia is affected by many changes, including the reform of the education system that plays a crucial role. The Ministry of Education together with Trade Unions (UGTT and the Arab Institute of Human Rights are tracing the outlines of the reform, through an experiment of participatory democracy, synthesized through the preparation of a national report, which is analyzed here. The reform aims to change profoundly the current educational system: programs, manuals, the training of teachers, teaching, all these aspects will be included. Faced with the current economic situation and the problems affecting the country, from the religious extremism to the economic crisis, attempts have been made to examine the solutions proposed by various players involved. After a brief historical reconstruction of the reforms that have affected the Tunisian school system, a current reform is discussed, focusing especially on the school textbooks and on the image of Europe that they carry. Based on the opening to the other, discussed in the manuals, how can one explain the diffusion of religious fanaticism among certain groups of young people? How can the school consolidate the emerging democracy? These are the questions that are tried to be answered, leaving open the possibility of different interpretations.

  10. Determination of Linke turbidity factor from solar radiation measurement in northern Tunisia

    The attenuation of solar radiation through a real atmosphere versus that through a clean dry atmosphere gives an indication of the atmospheric turbidity. Study of atmospheric turbidity is important in meteorology, climatology and for monitoring of atmospheric pollution. The Linke turbidity factor refers to the whole spectrum, that is, overall spectrally integrated attenuation, which includes presence of gaseous water vapour and aerosols. In this work, a procedure for calculation of Linke turbidity factor is adopted using pyrheliometric measurements in a coastal tourist location in Tunisia (Sidi Bou Said), during three summer months (June, July and August 1999). Real diurnal and monthly variations of the T L turbidity factor are found in the three studied months, with a maximum in August afternoon and a minimum in July morning. The increase of T L is an indication for increasing atmospheric turbidity level (pollution). The correlation between atmospheric turbidity and the local weather conditions shows that this increase is essentially due to the heavy water vapour content of maritime air masses, carried by the north-eastern winds prevalent during the afternoon. A second pollution source is the dust content of the continental air masses carried by western and southern winds prevalent in the morning. Next to this can be added the influence of traffic at rush hours and during the afternoon of summer holidays. (Author)

    The volatiles obtained separately from the terminal branches (woody and non-woody), cones and roots of Tetraclinis articulata gathered from the area of Zaghouan (Tunisia) have been analyzed by GC and GC-MS. Remarkable differences were found between the constituent percentages of the different studied organs. The main components in the non-woody branches volatile oil were naphtalen (6.6%), Z-muurolene (29.0%) while Camphene (43.2%), Z-beta-ocimene (11.7%), nonanol (5.3%) and a non identified compound (12%) were the main components in the wood branches volatile concentrate. In the cones oil, the most important compounds found were trans-pinacarveol (6.1%), p-cymene-8-ol (10.4%), fenchyl acetate (5.1%), beta-phellandrene (8.1%) and carvone (5.3%). The major constituent in the oil of roots was found to be Camphene (70.2%). A comparison of these data with previous results reported in the literature showed surprising differences.

    Full Text Available Background. Enteric diseases are an important concern to the poultry industry and coccidiosis is imposing a significant economic burden worldwide. Objectives. The main goal of the present study was to investigate the prevalence of coccidiosis in free-range chicken in Sidi Thabet, northeast Tunisia. Methods. Six hundred and thirty free-range chickens along with fecal samples were collected from 15 flocks in this region and two hundred chickens were found positive for oocysts of Eimeria spp. Intestines were dissected and examined for macroscopic lesions. The mucosa of small intestine and the caeca were examined for the presence and identification of parasitic forms using parasitology methods. The mean lesion scores were usually low (2+ were attributed mainly to the caeca. Results. The overall rate of coccidiosis was 31.8%: E. tenella (61.5%, E. maxima (12%, and E. acervulina (1.5%. Mixed Eimeria species infection was observed with overall prevalence 26.5%. There was a statistically significant difference (P<0.05 among infection rates, age groups, season, diarrhea, and type of chicken. Conclusion. This is the first report of coccidiosis rate in free-range chicken in this region. Further additional studies are needed to develop better preventive measures against coccidiosis in the country.

    Full Text Available Fifty-eight patients on maintenance hemodialysis in a dialysis unit at Tunis, Tunisia were tested for anti-hepatitis C virus (anti-HCV antibodies by second generation ELISA test, and for HCV-RNA by nested reverse transcriptase polymerase chain reaction (RT-PCR of 5′ non-coding region. Specificity of the antibodies was confirmed by immunoblot test. HCV genotype was defined using INNO-LIPA test. Twenty-seven out of 58 patients (46.5% were reactive by ELISA. Transaminase levels were assessed over a six-month period and showed normal average values. Fourteen of the 27 anti-HCV positive patients (51% were positive by RT-PCR. Type 1b HCV genotype was the most prevalent, seen in all the dialysis patients and one patient in addition, was co-infected with genotype 4. There was a significant correlation between the duration on dialysis (over five years and the prevalence of anti-HCV-positive patients (P< 0.005 while no correlation existed between the number of blood transfusions and the presence of anti-HCV antibodies. The present study illustrates the high prevalence of HCV infection among Tunisian dialysis patients (51% and indicates that the spread may be nosocomial rather than transfusion-related.

    Atmospheric and climatic data measured at Thala site (Tunisia) for a long-time period (1977-2001) are used to analyse the monthly, seasonal, and annual variations of the aerosol optical depth at 1 μm wavelength. We have shown that aerosol and microphysical properties and the dominating aerosol types depend on seasons. A comparison of the seasonal cycle of aerosol optical characteristics at Thala site showed that the contribution of long-range transported particles is expected to be larger in summer as a consequence of the weather stability typical of this season. Also, the winter decrease in atmospheric turbidity may result from increases in relative humidity and decreases in temperature, leading to increased particle size and mass and increased fall and deposition velocities. The spring and autumn weather patterns usually carry fine dust and sand particles for the desert area to Thala region. The annual behaviour of the aerosol optical depth recorded a period of stead increase started in 1986 until 2001. Trends in atmospheric turbidity after 1988 could be explained other ways by the contribution of the eruption of Mount Pinatubo in 1991 and by local or regional changes in climate or in aerosol emissions.

    This work shows the results of various analysis on a representative clay sample from southern west of Tunisia, particularly from Oued Tfal near the town of Gafsa. The raw smectite contains some carbonate, quartz, chlorite, and anorthite. During the attack of the carbonate clay with a solution of hydrochloric acid, a change of the chemical composition and physical properties was observed. This change is dependent on several factors: the initial concentration of the acid, the nature of the clay, the ratio acid / clay...). Although treatment to 0.5 M represents a total removal of carbonates, there are probably altered layers of the clay fraction. The result shows that for a treatment with acid solutions of concentrations below 0.5 M there is gradual removal of carbonate without protonation of the clay layers. The characterization of the clay fraction shows that the sodium clay purified (OTNa) consists of a sodium montmorillonite smectite. The cation exchange capacity and the specific surface of OTNa measured using the method of methylene blue are equal to 82 meq/100g and 667 m 2 / g respectively.

    Antibiotics are among the most commonly used group of pharmaceuticals in human medicine. They can therefore reach surface and groundwater bodies through different routes, such as wastewater treatment plant effluents, surface runoff, or infiltration of water used for agricultural purposes. It is well known that antibiotics pose a significant risk to environmental and human health, even at low concentrations. The aim of the present study was to evaluate the presence of aminoglycosides and phenicol antibiotics in municipal wastewaters, sea water and pharmaceutical effluents in Tunisia. All analysed water samples contained detectable levels of aminoglycoside and phenicol antibiotics. The highest concentrations in wastewater influents were observed for neomycin and kanamycin B (16.4 ng mL(-1) and 7.5 ng mL(-1), respectively). Chloramphenicol was found in wastewater influents up to 3 ng mL(-1). It was observed that the waste water treatment plants were not efficient in completely removing these antibiotics. Chloramphenicol and florfenicol were found in sea water samples near aquaculture sites at levels up to, respectively, 15.6 ng mL(-1) and 18.4 ng mL(-1). Also aminoglycoside antibiotics were found near aquaculture sites with the highest concentration of 3.4 ng mL(-1) for streptomycin. In pharmaceutical effluents, only gentamycin was found at concentrations up to 19 ng mL(-1) over a sampling period of four months.

    The Neogene sedimentary basins (Serravallian to Quaternary) of the Tellian tectonic foreland in north-eastern Tunisia formed within the overall NE-SW sinistral strike-slip tectonic framework of the Ras El Korane-Thibar and El Alia-Teboursouk fault systems. From stratigraphic logs, structural cross sections and interpretation of 2D seismic lines and boreholes, the pre-Neogene basement can be interpreted to be structured according to Eocene (NW-SE) compressional and Oligocene extensional phases. This basement comprises structural highs (anticlines and horsts) and subsiding areas (synclines, half-grabens and grabens) formed during the Neogene. The subsiding areas are delineated by faults striking N030E, N-S and N140E, defining (i) narrow, strongly subsiding synclines, (ii) lozenge-shaped basins and (iii) trapezoidal basins. The architecture of their fill results from the sedimentary balance between tectonics and eustatism. Halokinesis and clay diapirism (driven by Triassic and Neogene evaporites and clays) also played an important role in basin evolution, contributing to the formation of domes and diapirs along active faults.

    Natural groundwater recharge under semi arid climate, like rainfall, is subjected to large variations in both time and space and is therefore very difficult to predict. Nevertheless, in order to set up any strategy for water resources management in such regions, understanding the groundwater recharge variability is essential. This work is interested in examining the impact of rainfall on the aquifer system recharge in the Northern Gafsa Plain in Tunisia. The study is composed of two main parts. The first is interested in the analysis of rainfall spatial and temporal variability in the study basin while the second is devoted to the simulation of groundwater recharge. Rainfall analysis was performed based on annual precipitation data recorded in 6 rainfall stations over a period of 56 years (1960-2015). Potential evapotranspiration data were also collected from 1960 to 2011 (52 years). The hydrologic distributed model WetSpass was used for the estimation of groundwater recharge. Model calibration was performed based on an assessment of the agreement between the sum of recharge and runoff values estimated by the WetSpass hydrological model and those obtained by the climatic method. This latter is based on the difference calculated between rainfall and potential evapotranspiration recorded at each rainy day. Groundwater recharge estimation, on monthly scale, showed that average annual precipitation (183.3 mm/year) was partitioned to 5, 15.3, 36.8, and 42.8% for interception, runoff, actual evapotranspiration and recharge respectively.

    Full Text Available One of the key points in the future of today’s political transition in Tunisia lies in the Islamists’ willingness to cooperate with the rest of the political parties to promote political change, as well as their electoral performance in the next elections. The aim of this article is to help reduce uncertainty on this issue, by clarifying its antecedents. With this aim, the author adopts as the article’s area of study the strategic-relational dimensions of Tunisia’s Islamist party’s performance in elections. With this in mind, the author analyses the types of interaction that the Islamist party maintained in the presidential elections of 2004 and 2009 with the other political and social parties that were critical of the Ben Ali regime, and examines its causes. As a result of this, the study concludes that up to now, both the party’s alignment with certain secular political and social actors from the structure of opposition to the Ben Ali regime, and its policy of confrontation with certain others, has not been based on any programmatic issue, nor on any issues of sensitivity or religious conception, but rather on the struggle to head political change and to lead a new government.
