  5. The Capes Current: a summer countercurrent flowing past Cape Leeuwin and Cape Naturaliste, Western Australia

    Science.gov (United States)

    Pearce, Alan; Pattiaratchi, Charitha

    1999-03-01

    Although the dominant boundary current off Western Australia is the poleward-flowing Leeuwin Current, satellite imagery shows that there is a cool equatorward coastal countercurrent running close inshore in the extreme southwest during the summer months. This seasonal current has been named the Capes Current as it appears to be strongest between Cape Leeuwin (34°20'S) and Cape Naturaliste (33°30'S), and it is probably linked with the general northward shelf current which has been observed previously along most of the Western Australian coastline further north. Strong northwards wind stresses between November and March slow the Leeuwin Current (which moves offshore) and drive the Capes Current, and there may be localised upwelling as well (Gersbach et al., Continental Shelf Research, 1998). It has important implications for the salmon fishery as it may affect the migration of adult salmon around Cape Leeuwin at this time of year.

    2007-01-01

    This Mars Exploration Rover Opportunity Pancam 'super resolution' mosaic of the approximately 6 m (20 foot) high cliff face of the Cape Verde promontory was taken by the rover from inside Victoria Crater, during the rover's descent into Duck Bay. Super-resolution is an imaging technique which utilizes information from multiple pictures of the same target in order to generate an image with a higher resolution than any of the individual images. Cape Verde is a geologically rich outcrop and is teaching scientists about how rocks at Victoria crater were modified since they were deposited long ago. This image complements super resolution mosaics obtained at Cape St. Mary and Cape St. Vincent and is consistent with the hypothesis that Victoria crater is located in the middle of what used to be an ancient sand dune field. Many rover team scientists are hoping to be able to eventually drive the rover closer to these layered rocks in the hopes of measuring their chemistry and mineralogy. This is a Mars Exploration Rover Opportunity Panoramic Camera image mosaic acquired on sols 1342 and 1356 (November 2 and 17, 2007), and was constructed from a mathematical combination of 64 different blue filter (480 nm) images.

  12. A 'private adventure'? John Herschel's Cape voyage and the production of the 'Cape Results'

    Science.gov (United States)

    Ruskin, Steven William

    2002-07-01

    This dissertation considers the life of John Herschel (1792 1871) from the years 1833 to 1847. In 1833 Herschel sailed from London to Cape Town, southern Africa, to undertake (at his own expense) an astronomical exploration of the southern heavens, as well as a terrestrial exploration of the area around Cape Town. After his return to England in 1838, he was highly esteemed and became Britain's most recognized scientist. In 1847 his southern hemisphere astronomical observations were published as the Cape Results. The main argument of this dissertation is that Herschel's voyage, and the publication of the Cape Results, in addition to their contemporary scientific importance, were also significant for nineteenth-century politics and culture. This dissertation is a two-part dissertation. The first part is entitled “John Herschel's Cape Voyage: Private Science, Public Imagination, and the Ambitions of Empire”; and the second part, “The Production of the Cape Results.” In the first part it is demonstrated that the reason for Herschel's cultural renown was the popular notion that his voyage to the Cape was a project aligned with the imperial ambitions of the British government. By leaving England for one of its colonies, and pursuing there a significant scientific project, Herschel was seen in the same light as other British men of science who had also undertaken voyages of exploration and discovery. It is then demonstrated, in the second part of this work, that the production of the Cape Results, in part because of Herschel's status as Britain's scientific figurehead, was a significant political and cultural event. In addition to the narrow area of Herschel scholarship, this dissertation touches on other areas of research in the history of science as well: science and culture, science and empire, science and politics, and what has been called the “new” history of scientific books.

  14. Geologic history of Cape Cod, Massachusetts

    Science.gov (United States)

    ,

    1976-01-01

    Cape Cod, a sandy peninsula built mostly during the Ice Age, juts into the Atlantic Ocean like a crooked arm. Because of its exposed location, Cape Cod was visited by many early explorers. Although clear-cut evidence is lacking, the Vikings may have sighted this land about 1,000 years ago. It was visited by Samuel de Champlain in 1605, and his detailed descriptions and charts have helped present-day scientists to determine the rate of growth of Nauset Beach marsh and Nauset spit. Bartholomew Gosnold, a lesser known explorer, settled for a short time on the Elizabeth Islands to the southwest and gave Cape Cod its name in 1602. The Pilgrims first landed in America on the tip of Lower Cape Cod after they were turned back from their more southerly destination by shoals between Cape Cod and Nantucket Island. On Cape Cod they found potable water and food and had their first fight with the natives. The Pilgrims, however, decided that this land was too isolated, too exposed, and too sandy to support them, and they sailed across Cape Cod Bay to establish Plymouth. These features remain today. Small villages are separated by large areas of forest, dune, beach, and marsh. This unspoiled natural beauty makes Cape Cod one of the most favored vacation areas for the people living in the thickly settled Northeastern States. Cape Cod is of particular interest to geologists because it was formed by glaciers very recently in terms of geologic time. During the Great Ice Age, (the Pleistocene Epoch which began 2 to 3 million years ago), glaciers advanced from the north into the temperate regions of the Earth. Glacial ice covered the land at least four times. Each advance was accompanied by a worldwide lowering of sea level because the source of the ice was water from the seas. When the glaciers melted, the climate and sea level were probably much like they are today. In fact, some scientists believe that the Earth is presently between glacial episodes and that ice once again will

    2017-03-01

    Full Text Available In this paper we have simulated a flow sheet of aqua ammonia refrigeration system using Cape Open simulator. The main aim of writing this paper is to compare the results obtained from thermodynamic simulation of aqua ammonia refrigeration system and the results obtained from the flow sheet simulation in Cape-Open to Cape-Open COCO simulator. The corresponding COP values obtained from both the sources are calculated and compared. With the error being very minute the calculations using simulator prove to be more efficient and timesaving when compared to the results obtained by calculations done using tedious thermodynamic simulations and constant mass balance for different process conditions.

  19. Patterns of plant speciation in the Cape floristic region.

    Science.gov (United States)

    van der Niet, Timotheüs; Johnson, Steven D

    2009-04-01

    Plant species have accumulated in the Cape region of southern Africa to a much greater degree than in areas of equivalent size in the rest of the subcontinent. Although this could be a consequence simply of lower extinction rates in the Cape, most researchers have invoked high rates of ecological speciation, driven by unique aspects of the Cape environment, as the primary explanation for this richness. To assess these ideas, we analyzed the frequencies of ecological shifts among 188 sister species pairs obtained from molecular phylogenies of eight Cape clades. Ecological shifts were evident in 80% of sister species pairs, with general habitat, pollinator, and fire-survival strategy shifts being especially frequent. Contrary to an established idea that shifts in soil type are frequently associated with speciation of Cape taxa, these shifts were relatively rare, occurring in just 17% of species pairs. More cases of sister species divergence are accompanied solely by floral than by vegetative diversification, suggesting an important role for pollinator-driven speciation. In an analysis of two large orchid genera that have radiated in both the Cape and the rest of southern Africa, the frequency of ecological shifts (general habitat, soil type, altitude and flowering time), did not differ between sister species pairs in the Cape region and those outside it. Despite suggestions that Cape plants tend to have small range sizes and show fine-scale patterns of speciation, range size did not differ significantly between species in the Cape and those outside it. We conclude that ecological speciation is likely to have been important for radiation of the Cape flora, but there is no evidence as yet for special "Cape" patterns of ecological speciation.

  20. Foraging range and habitat use by Cape Vulture Gyps coprotheres from the Msikaba colony, Eastern Cape province, South Africa

    Morgan B. Pfeiffer

    2015-05-01

    Full Text Available Despite the extent of subsistence farmland in Africa, little is known about endangered species that persist within them. The Cape Vulture (Gyps coprotheres is regionally endangered in southern Africa and at least 20% of the population breeds in the subsistence farmland area previously known as the Transkei in the Eastern Cape province of South Africa. To understand their movement ecology, adult Cape Vultures (n = 9 were captured and fitted with global positioning system/global system for mobile transmitters. Minimum convex polygons (MCPs,and 99% and 50% kernel density estimates (KDEs were calculated for the breeding and non breeding seasons of the Cape Vulture. Land use maps were constructed for each 99% KDE and vulture locations were overlaid. During the non-breeding season, ranges were slightly larger(mean [± SE] MCP = 16 887 km2 ± 366 km2 than the breeding season (MCP = 14 707 km2 ± 2155 km2. Breeding and non-breeding season MCPs overlapped by a total of 92%. Kernel density estimates showed seasonal variability. During the breeding season, Cape Vultures used subsistence farmland, natural woodland and protected areas more than expected. In the non-breeding season, vultures used natural woodland and subsistence farmland more than expected, and protected areas less than expected. In both seasons, human-altered landscapes were used less, except for subsistence farmland. Conservation implications: These results highlight the importance of subsistence farm land to the survival of the Cape Vulture. Efforts should be made to minimise potential threats to vultures in the core areas outlined, through outreach programmes and mitigation measures.The conservation buffer of 40 km around Cape Vulture breeding colonies should be increased to 50 km.

  9. The Cape Times's portrayal of school violence

    Directory of Open Access Journals (Sweden)

    Corene de Wet

    2016-05-01

    Full Text Available This study explores the Cape Times's portrayal of school violence in the Western Cape (WC, South Africa, reporting on findings from a qualitative content analysis of 41 news articles retrieved from the SA Media database. The findings shed light on the victims and their victimisation, the perpetrators, as well as the context of the violence, identifying gangsterism, as well as school administrative and community factors as the reasons for violence in WC schools. It is argued that school violence and gangsterism are inextricably linked to the Cape Flats in particular, and that the interaction of forms of inequality and oppression such as racism, class privilege and gender oppression are structural root causes for school violence in this area of the WC. The study highlights the negative consequences of school violence on teaching and learning and on the economy. It is concluded that even if the Cape Times paints an exaggerated and atypical picture of violence in the gang-riddled parts of the WC, the detrimental effects thereof on the regions cannot be denied. The study therefore recommends a holistic approach to addressing the structural root causes of school violence where it takes place in the WC.

    Full Text Available The article analyzes, from an ethnographic and historical perspective, the relations between memory, identity and Afro-descendant political activism among the Argentine-Cape Verdeans from Buenos Aires. The article highlights the memories and stories of the independence of Cape Verde, and the role played in it by Amílcar Cabral, the main political leader of this process. These narratives, whose specific expression are reflected in the institutional space of the Cape Verdean Society of Dock Sud, are updated from different perspectives and redefine the changing identity borders that allow the delineation of specific forms of political activism in Buenos Aires.

  11. Geostationary Coastal and Air Pollution Events (GEO-CAPE) Sensitivity Analysis Experiment

    Lee, Meemong; Bowman, Kevin

    2014-01-01

    Geostationary Coastal and Air pollution Events (GEO-CAPE) is a NASA decadal survey mission to be designed to provide surface reflectance at high spectral, spatial, and temporal resolutions from a geostationary orbit necessary for studying regional-scale air quality issues and their impact on global atmospheric composition processes. GEO-CAPE's Atmospheric Science Questions explore the influence of both gases and particles on air quality, atmospheric composition, and climate. The objective of the GEO-CAPE Observing System Simulation Experiment (OSSE) is to analyze the sensitivity of ozone to the global and regional NOx emissions and improve the science impact of GEO-CAPE with respect to the global air quality. The GEO-CAPE OSSE team at Jet propulsion Laboratory has developed a comprehensive OSSE framework that can perform adjoint-sensitivity analysis for a wide range of observation scenarios and measurement qualities. This report discusses the OSSE framework and presents the sensitivity analysis results obtained from the GEO-CAPE OSSE framework for seven observation scenarios and three instrument systems.

  12. Reconstruction of major maternal and paternal lineages of the Cape Muslim population

    Full Text Available The earliest Cape Muslims were brought to the Cape (Cape Town -South Africa from Africa and Asia from 1652 to 1834. They were part of an involuntary migration of slaves, political prisoners and convicts, and they contributed to the ethnic diversity of the present Cape Muslim population of South Africa. The history of the Cape Muslims has been well documented and researched however no in-depth genetic studies have been undertaken. The aim of the present study was to determine the respective African, Asian and European contributions to the mtDNA (maternal and Y-chromosomal (paternal gene pool of the Cape Muslim population, by analyzing DNA samples of 100 unrelated Muslim males born in the Cape Metropolitan area. A panel of six mtDNA and eight Y-chromosome SNP markers were screened using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP. Overall admixture estimates for the maternal line indicated Asian (0.4168 and African mtDNA (0.4005 as the main contributors. The admixture estimates for the paternal line, however, showed a predominance of the Asian contribution (0.7852. The findings are in accordance with historical data on the origins of the early Cape Muslims.

    Rocchi, S.; Fioretti, A.M.; Cavazzini, G.

    2002-01-01

    The Meander Intrusive Group is the plutonic-subvolcanic counterpart of the McMurdo Volcanic Group, and extends along 200 km of the Ross Sea coast of Northern Victoria Land. The three largest occurrences of the Meander Intrusive Group between the Icebreaker and Borchgrevink glaciers are the Cape Crossfire, the No Ridge, and the Cape King igneous complexes. These have an area of 40-80 square km and are composed of dominant monzogabbros and monzodiorites along with minor syenites and alkali feldspar microgranites. A significant compositional gap exists between mafic and felsic facies, which show geometrical relationships varying from subhorizontal alternating layers to complex pillowing and fragmentation of the mafic into the felsic facies. Two whole rock biotite Rb-Sr internal isochrons constrain the cooling age of Cape Crossfire Igneous Complex at 31 Ma, a few million years older than No Ridge and Cape King igneous complexes. Thus, the ages of these complexes (≤ 31 Ma) are younger than the plutons and dikes (≥ 35 Ma) cropping out in the southernmost area between the Campbell and Icebreaker glaciers.

  16. A Cretaceous origin for fire adaptations in the Cape flora.

    Science.gov (United States)

    He, Tianhua; Lamont, Byron B; Manning, John

    2016-10-05

    Fire has had a profound effect on the evolution of worldwide biotas. The Cape Floristic Region is one of the world's most species-rich regions, yet it is highly prone to recurrent fires and fire-adapted species contribute strongly to the overall flora. It is hypothesized that the current fire regimes in the Cape could be as old as 6-8 million years (My), while indirect evidence indicates that the onset of fire could have reached 18 million years ago (Ma). Here, we trace the origin of fire-dependent traits in two monocot families that are significant elements in the fire-prone Cape flora. Our analysis shows that fire-stimulated flowering originated in the Cape Haemodoraceae 81 Ma, while fire-stimulated germination arose in the African Restionaceae at least 70 Ma, implying that wildfires have been a significant force in the evolution of the Cape flora at least 60 My earlier than previous estimates. Our results provide strong evidence for the presence of fire adaptations in the Cape from the Cretaceous, leading to the extraordinary persistence of a fire-adapted flora in this biodiversity hotspot, and giving support to the hypothesis that Cretaceous fire was a global phenomenon that shaped the evolution of terrestrial floras.

  17. A review of Khoi-San and Cape Dutch medical ethnobotany.

    Science.gov (United States)

    van Wyk, B-E

    2008-10-28

    ETHNOPHARMACOLOGICAL CONTEXT: Cape herbal medicine as a distinct and unique healing system is conceptualized for the first time, together with a first compilation of the authentic materia medica of the system. The early literature on Khoikhoi (Hottentot), San (Bushman) and Cape Dutch medicinal plants and medical practices is reviewed, with a focus on the Cape Floristic Region (from Namaqualand to the Eastern Cape). To avoid recent additions and modern cultural influences in the results, the date of publication of the last volume of Marloth's Flora of South Africa (1932) was chosen as a cut-off date. The recorded Cape materia medica (up to 1932) is briefly summarized, giving the scientific names, vernacular names (in Afrikaans or Khoi-San/Nama) and main uses. It comprises about 170 items and includes mainly indigenous and endemic plant species, some exotic (garden) plants, and a few other items (fungi, seaweeds, lichens, hyraceum and natural potassium nitrate). Most of the plants (and hyraceum) are still widely used today, especially in rural areas. The combination of unique cultural practices and a diverse, highly endemic flora has led to the development of a distinct herbal healing system, here called Cape herbal medicine, but hitherto rather vaguely and inaccurately referred to as Khoi-San medicine, Cape Dutch medicine or boererate (farm remedies). The data allows for a more informed consideration of indigenous knowledge and intellectual property rights associated with particular plants (e.g. Hoodia and Pelargonium). It also offers opportunities for linking modern ethnobotanical field studies with historical data.

    Full Text Available The four major phytochoria of southern Africa, the Cape. Tongoland-Pondoland. Karoo-Namib and Afromontane regions, converge in the complex transition zone of the eastern Cape. The area is rich in species and communities with a complex vegetation in which are represented all the major vegetation formations of southern Africa — Cape Fynbos. Cape Transitional Shrublands, Subtropical Thicket. Karoo, Savanna, Afromontane Forest, Grasslands and Littoral Strand Vegetation. Our results support previous findings that, although species-rich and of great diversity, the flora has fewer endemics (205 or 5,6% than the Cape (73% or Karoo-Namib (35%.  The communities with the largest proportion of endemics (30%, and threatened plants (18% are those of the Subtropical Thicket. On the basis of these data and an index of conserv ation status, the Subtropical Thicket was determined to be highest on the priority list for conservation in the eastern Cape. Subtropical Thicket is being cleared at an increasing rate and is most vulnerable due to changing farming practice.

    Nowadays, the lack of adequate housing in Cape Verde is a growing problem. The migration of the population living in the countryside to the major cities generates an increase of the diameter of the cities. With the lack of economic power, the migrating families tend to occupy the land with houses which don't present proper conditions to living. Praia is the capital of Cape Verde and so on the biggest city of the country. This fact leads Praia to being the city with major economic power and job offer in all country. Consequently, Praia has developed the biggest slum of the Cape Verde and it is urgent to approach this problem in order to create solutions that reveal capacity to start solving it. Cape Verde's unique dry subtropical climate turns indispensable a careful resolution of the housing, in order to ensure the comfort of the occupants. The modular construction is a solution with potential to approach this problem with a fast and economic response. In order to answer the situation, this article introduces a modular solution in order to reach the needing of thermal comfort to the specific case of Praia.

    The Cape Verde Archipelago ((15-17°N, 23-26°W) is located within the African plate, about 500km west of Senegal, in the African coast. The islands are located astride the Cape Verde mid-plate topographic swell, one of the largest features of its type in the world's ocean basins. The origin of this Cape Verde swell is still in debate. Previous determinations of the elastic thickness (Te) reveal a normal Te and a modest heat flow anomaly which suggest that the swell cannot be fully explained by uplift due to thermal reheating of the lithosphere by an underlying ‘‘hot spot'' and that other, deep-seated, mantle processes must be involved. The CV-PLUME (An investigation on the geometry and deep signature of the Cape Verde mantle plume) project intends to shape the geometry and deep origin of the Cape Verde mantle plume, via a combined study of seismic, magnetic, gravimetric and geochemical observations. Through this study we intend to characterize the structure beneath the archipelago from the surface down to the deep mantle. The core of this 3-year project was a temporary deployment of 39 Very Broad Band seismometers, across all the inhabited islands, to recorder local and teleseismic earthquakes. These instruments were operational from November 2007 to September 2008. In this work we report on the preliminary results obtained from the CV-PLUME network on the characterization of the local and regional seismicity. To detect the small magnitude seismic events the continuous data stream was screened using spectrograms. This proved to be a very robust technique in the face of the high short-period noise recorded by many of the stations, particularly during day time. The 10 month observation time showed that the background seismic activity in the Archipelago and surrounding area is low, with only a very few events recorded by the complete network. However, two clusters of earthquakes were detected close to the Brava Island, one to the NW and a second one, more active

    Full Text Available Cape Town is a fast-growing cityscape in the Cape Floristic Region in South Africa with 24 formally protected conservation areas including the World Heritage Table Mountain National Park. These sites have been protected and managed as critical sites for local biodiversity, representing potentially one-third of all Cape Floristic Region flora species and 18% of South Africa's plant diversity. Cape Town is also inhabited by a rapidly growing culturally and economically diverse citizenry with distinct and potentially conflicting perspectives on access to, and management of, local natural resources. In a qualitative study of 58 locally resident traditional healers of distinct cultural groups, we examined motivations underlying the generally illicit activity of harvesting of wild resources from Cape Town protected areas. Resource harvester motivations primarily link to local economic survival, health care and cultural links to particular resources and practices, 'access for all' outlooks, and wholesale profit-seeking perspectives. We describe these motivations, contrast them with the current formal, legal and institutional perspectives for biodiversity protection in the city, and propose managerial interventions that may improve sustainability of ongoing harvest activities. Significance: The study reveals, for the first time in the Cape Floristic Region, informal economy viewpoints on terrestrial nature and how its direct use has important economic and cultural roles – specifically in wild medicine harvesting and trade. We contrast the formal and informal approaches to nature conservation in the city and propose new considerations for conservation managers.

    Objective: To study the radiosensitizing effect of caffic acid phenethyl ester (CAPE) on human cervical cancer HeLa cells. Methods: MTT assay was used to measure the relation between the inhibition effect and CAPE concentrations by CAPE with different concentrations on HeLa cells for 24 hours. HeLa cells were divided into the control and experimental groups, both of which were given 0, 2, 4, 6 and 8 Gy of 60Co γ-irradiation, respectively. The cell clones were counted. Meanwhile HeLa cells were divided into the control, CAPE, irradiation and combination groups. Flow cytometric analysis was adopted to detect the changes of cell cycle distribution induced by CAPE. Results: The inhibition rate of CAPE acting on Hela cells increased with concentrations (F=126. 49 ∼ 3654.88, P 0 ) (1.45 and 1.82 Gy) and the quasi-threshold dose (D q ) (1.89 and 3.21 Gy) of HeLa cells in experimental group decreased comparing with control group, SER was 1.26. Compared with the sole irradiation group, cells in G 2 /M phase of the CAPE group and the sole irradiation group increased (P 2 /M arrest and may be related to the inhibition of the sub-lethal damage repair.

    Full Text Available Tourists pay for destination brands. This study checked for the relationships between tourists’ profile and how they perceived the destination brand of Cape Town. A questionnaire survey of 220 tourists visiting Cape Town was done. This study found that repeat visit, age of tourist, length of stay, and tourist origin, have significant influences on how tourists visiting Cape Town perceived the destination. The top three destination attributes of Cape Town (cognitive images, which enhance visitor experience satisfaction are (1 the overall level of service quality at facilities in Cape Town, (2 the city being one of the best places the tourists have visited, and (3 the destination’s good value for money. The top three emotional valuations of destination attributes (affective images which enhance visitor experience satisfaction in Cape Town include (1 memorable visit, (2 valuable visit, and (3 friendly and hospitable population. It is therefore recommended that tourism businesses in Cape Town develop relationship marketing tools to attract and retain its tourists segments of loyal, advanced in age, long-staying and domestic tourists. Results from this research could be compared with related findings in the international arena and have related implications, especially for developing economies

    This paper considers the complexity of Muslim women’s identities in the city of Cape Town in 2010. It is argued that emerging super-diversity in the form of African immigration, the commercialisation of Islam and increasing freedoms for women in South Africa impact on women’s engagement with religion and diversifies their identity. The paper also offers glimpses into the diversity of Islam in Cape Town, suggesting that this religion is not monolithic in the city and that it is continuously di...

  15. The continental slope current system between Cape Verde and the Canary Islands

    Directory of Open Access Journals (Sweden)

    Jesús Peña-Izquierdo

    2012-08-01

    Full Text Available We use hydrographic, velocity and drifter data from a cruise carried out in November 2008 to describe the continental slope current system in the upper thermocline (down to 600 m between Cape Verde and the Canary Islands. The major feature in the region is the Cape Verde Frontal Zone (CVFZ, separating waters from tropical (southern and subtropical (northern origin. The CVFZ is found to intersect the slope north of Cape Blanc, between 22°N and 23°N, but we find that southern waters are predominant over the slope as far north as 24°N. South of Cape Blanc (21.25°N the Poleward Undercurrent (PUC is a prominent northward jet (50 km wide, reaching down to 300 m and indistinguishable from the surface Mauritanian Current. North of Cape Blanc the upwelling front is found far offshore, opening a near-slope northward path to the PUC. Nevertheless, the northward PUC transport decreases from 2.8 Sv at 18°N to 1.7 Sv at 24°N, with about 1 Sv recirculating ofshore just south of Cape Blanc, in agreement with the trajectory of subsurface drifters. South of the CVFZ there is an abrupt thermohaline transition at σϴ=26.85 kg m–3, which indicates the lower limit of the relatively pure (low salt and high oxygen content South Atlantic Central Water (SACW variety that coexists with the dominant locally-diluted (salinity increases through mixing with North Atlantic Central Water but oxygen diminishes because of enhanced remineralization Cape Verde (SACWcv variety. At 16°N about 70% of the PUC transport corresponds to the SACW variety but but this is transformed into 40% SACWcv at 24°N. However, between Cape Verde and Cape Blanc and in the 26.85 < σϴ < 27.1 layer, we measure up to 0.8 Sv of SACWcv being transported south. The results strongly endorse the idea that the slope current system plays a major role in tropical-subtropical water-mass exchange.

  18. Clausius-Clapeyron Scaling of Convective Available Potential Energy (CAPE) in Cloud-Resolving Simulations

    Science.gov (United States)

    Seeley, J.; Romps, D. M.

    2015-12-01

    Recent work by Singh and O'Gorman has produced a theory for convective available potential energy (CAPE) in radiative-convective equilibrium. In this model, the atmosphere deviates from a moist adiabat—and, therefore, has positive CAPE—because entrainment causes evaporative cooling in cloud updrafts, thereby steepening their lapse rate. This has led to the proposal that CAPE increases with global warming because the strength of evaporative cooling scales according to the Clausius-Clapeyron (CC) relation. However, CAPE could also change due to changes in cloud buoyancy and changes in the entrainment rate, both of which could vary with global warming. To test the relative importance of changes in CAPE due to CC scaling of evaporative cooling, changes in cloud buoyancy, and changes in the entrainment rate, we subject a cloud-resolving model to a suite of natural (and unnatural) forcings. We find that CAPE changes are primarily driven by changes in the strength of evaporative cooling; the effect of changes in the entrainment rate and cloud buoyancy are comparatively small. This builds support for CC scaling of CAPE.

    Evaluation is important for judiciously allocating limited conservation resources and for improving conservation success through learning and strategy adjustment. We evaluated the application of systematic conservation planning goals and conservation gains from incentive-based stewardship interventions on private land in the Cape Lowlands and Cape Floristic Region, South Africa. We collected spatial and nonspatial data (2003-2007) to determine the number of hectares of vegetation protected through voluntary contractual and legally nonbinding (informal) agreements with landowners; resources spent on these interventions; contribution of the agreements to 5- and 20-year conservation goals for representation and persistence in the Cape Lowlands of species and ecosystems; and time and staff required to meet these goals. Conservation gains on private lands across the Cape Floristic Region were relatively high. In 5 years, 22,078 ha (27,800 ha of land) and 46,526 ha (90,000 ha of land) of native vegetation were protected through contracts and informal agreements, respectively. Informal agreements often were opportunity driven and cheaper and faster to execute than contracts. All contractual agreements in the Cape Lowlands were within areas of high conservation priority (identified through systematic conservation planning), which demonstrated the conservation plan's practical application and a high level of overlap between resource investment (approximately R1.14 million/year in the lowlands) and priority conservation areas. Nevertheless, conservation agreements met only 11% of 5-year and 9% of 20-year conservation goals for Cape Lowlands and have made only a moderate contribution to regional persistence of flora to date. Meeting the plan's conservation goals will take three to five times longer and many more staff members to maintain agreements than initially envisaged. © 2010 Society for Conservation Biology.

    2004-01-01

    Caffeic acid phenethyl ester (CAPE) is a biologically active ingredient of honeybee propoplis. The cytotoxicity and radiation sensitization effects of CAPE were evaluated in human lung cancer A549 cells and normal lung fibroblast WI-38 cells. A549 cells treated with 6 μg/ml CAPE showed marked growth inhibition (60%) at 48 hr after treatments. During the same time, the number of viable cells decreased to 46% of the control value. In contrast, WI-38 cells showed 20% growth inhibition with no change in the number of viable cells under the same treatment conditions. At 72 hr after CAPE treatment (6 μg/ml), the percentage of apoptotic cells in A549 cultures increased significantly to 67% and an S/G2 arrest was also detected in the culture. Furthermore, there was a significant decrease in the level of intracellular glutathione and hydrogen peroxide contents within one hr after CAPE treatment, and the expression of cyclin B 1 was reduced 6 hr after treatment. The radiation sensitization effect of CAPE on A549 cells was determined from the clonogenic survival curves, and the results showed a small but significant difference in radiation survival between cells treated with or without CAPE. Taken together, our results suggest that the effects of CAPE on differential cytotoxicity, apoptosis, and radiosensitization are associated with glutathione depletion that occurred shortly after treatments.

    Cape Verde petrel (Pterodroma feae) is currently considered near threatened, but little is known about its population size, breeding biology and on land threats, jeopardizing its management and conservation. To improve this situation, we captured, marked and recaptured (CMR) birds using mist-nets over 10 years; measured and sexed them; monitored up to 14 burrows, deployed GPS devices on breeders and analyzed activity data of geolocators retrieved from breeders in Fogo (Cape Verde). We set cat traps over the colony and investigated their domestic/feral origin by marking domestic cats from a nearby village with transponders, by deploying GPS devices on domestic cats and by performing stable isotope analyses of fur of the trapped and domestic cats. The population of Fogo was estimated to be 293 birds, including immatures (95% CI: 233-254, CMR modelling). Based on geolocator activity data and nest monitoring we determined the breeding phenology of this species and we found biometric differences between sexes. While monitoring breeding performance, we verified a still ongoing cat predation and human harvesting. Overall, data gathered from trapped cats without transponder, cats GPS trips and the distinct isotopic values between domestic and trapped cats suggest cats visiting the colony are of feral origin. GPS tracks from breeders showed birds left and returned to the colony using the sector NE of the islands, where high level of public lights should be avoided specially during the fledging period. Main threats for the Cape Verde petrel in the remaining breeding islands are currently unknown but likely to be similar to Fogo, calling for an urgent assessment of population trends and the control of main threats in all Cape Verde Islands and uplisting its conservation status.

  10. Why does tropical convective available potential energy (CAPE) increase with warming?

    Science.gov (United States)

    Seeley, Jacob T.; Romps, David M.

    2015-12-01

    Recent work has produced a theory for tropical convective available potential energy (CAPE) that highlights the Clausius-Clapeyron (CC) scaling of the atmosphere's saturation deficit as a driver of increases in CAPE with warming. Here we test this so-called "zero-buoyancy" theory for CAPE by modulating the saturation deficit of cloud-resolving simulations of radiative-convective equilibrium in two ways: changing the sea surface temperature (SST) and changing the environmental relative humidity (RH). For earthlike and warmer SSTs, undilute parcel buoyancy in the lower troposphere is insensitive to increasing SST because of a countervailing CC scaling that balances the increase in the saturation deficit; however, buoyancy increases dramatically with SST in the upper troposphere. Conversely, in the RH experiment, undilute buoyancy throughout the troposphere increases monotonically with decreasing RH. We show that the zero-buoyancy theory successfully predicts these contrasting behaviors, building confidence that it describes the fundamental physics of CAPE and its response to warming.

  13. Urban Ecology in Cape Town: South African Comparisons and Reflections

    Directory of Open Access Journals (Sweden)

    Sarel S. Cilliers

    2012-09-01

    Full Text Available Little urban ecological research has been done in South Africa. The papers in the Ecology and Society special feature Urban Ecological and Social-Ecological Research in the City of Cape Town make, therefore, an important contribution to the development of urban ecology locally and globally. Different approaches have been used in the study of urban ecology of different urban areas in South Africa. Cape Town is situated in a biodiversity hotspot and is the only South African city which includes a national park. As a result the urban ecological studies were mainly driven by urban nature conservation concerns. In other cities such as Durban, open space planning and environmental management were the major issues which focused ecological studies on urban areas whereas other studies of urban areas in the Eastern Cape and North-West provinces included private and public open spaces and man-made habitats. We reflect on the Cape Town studies in a South African context and highlight conservation of biodiversity, protection of ecosystem services, management of control measures, and the conflict between humans and nature. A brief synthesis has also been given of South African urban ecological research in general.

  14. Continuous Flow of Upper Labrador Sea Water around Cape Hatteras.

    Science.gov (United States)

    Andres, Magdalena; Muglia, Mike; Bahr, Frank; Bane, John

    2018-03-14

    Six velocity sections straddling Cape Hatteras show a deep counterflow rounding the Cape wedged beneath the poleward flowing Gulf Stream and the continental slope. This counterflow is likely the upper part of the equatorward-flowing Deep Western Boundary Current (DWBC). Hydrographic data suggest that the equatorward flow sampled by the shipboard 38 kHz ADCP comprises the Upper Labrador Sea Water (ULSW) layer and top of the Classical Labrador Sea Water (CLSW) layer. Continuous DWBC flow around the Cape implied by the closely-spaced velocity sections here is also corroborated by the trajectory of an Argo float. These findings contrast with previous studies based on floats and tracers in which the lightest DWBC constituents did not follow the boundary to cross under the Gulf Stream at Cape Hatteras but were diverted into the interior as the DWBC encountered the Gulf Stream in the crossover region. Additionally, our six quasi-synoptic velocity sections confirm that the Gulf Stream intensified markedly at that time as it approached the separation point and flowed into deeper waters. Downstream increases were observed not only in the poleward transport across the sections but also in the current's maximum speed.

    Problem- In the townships and rural areas of the Western Cape province of South Africa unemployment can be as high as 60%. For many, starting a business is the only viable option to survive. There are many organizations seeking to help entrepreneurs to successfully start and manage a business, but services are significantly lacking. We therefore wish to determine what business service providers in the Western Cape are doing today to help necessity entrepreneurs succeed, and what can be done b...

  16. Is a changing climate affecting the tropical cyclone behavior of Cape Verde?

    2016-12-01

    An existing dataset of synthetic tropical cyclone (TC) tracks derived from climate change simulations were used to explore TC variability within a 250 km radius of the Cape Verde Islands (16.5388N, 23.0418W). The synthetic sets were examined according to genesis point location, track projection, intensity, frequency, and seasonality within the observational era (1851 AD to present). These factors of TC variability have been shown to be strongly related to climate oscillations, thus the historical era was grouped by the increasing and decreasing regimes of sea surface temperature (SST) in the main development region (MDR) of the Atlantic Ocean. Numerous studies have examined Atlantic Basin activity throughout this era; the goal of this study is to investigate possible variations in TC behavior around Cape Verde, ultimately determining whether Cape Verde experiences similar fluctuations in activity as observed basin-wide. We find that several facets of TC variability such as intensity, seasonality, and genesis point location around Cape Verde are not significantly different to that of the entire basin, thus forecasts of the entire basin in these respects may also apply to our site. A long-term trend of increasing TC frequency can be identified basin-wide within the observed set, yet activity around Cape Verde does not display this same behavior observably or in any synthetic set. A relationship between the location of genesis points and the regimes of SST fluctuation is shown to be existent. We find both more observed and synthetic genesis points within the vicinity of Cape Verde during cool periods, and an eastward and equatorward shift in cyclogenesis is evident during warm regimes. This southeastern shift in genesis points attributes to the increased intensities of TCs seen during periods of warmer SST. Years of increased SST are additionally linked to an earlier seasonality in Cape Verde.

  17. Analysis of bathymetric surveys to identify coastal vulnerabilities at Cape Canaveral, Florida

    Science.gov (United States)

    Thompson, David M.; Plant, Nathaniel G.; Hansen, Mark E.

    2015-10-07

    Cape Canaveral, Florida, is a prominent feature along the Southeast U.S. coastline. The region includes Merritt Island National Wildlife Refuge, Cape Canaveral Air Force Station, NASA’s Kennedy Space Center, and a large portion of Canaveral National Seashore. The actual promontory of the modern Cape falls within the jurisdictional boundaries of Cape Canaveral Air Force Station. Erosion hazards result from winter and tropical storms, changes in sand resources, sediment budgets, and sea-level rise. Previous work by the USGS has focused on the vulnerability of the dunes to storms, where updated bathymetry and topography have been used for modeling efforts. Existing research indicates that submerged shoals, ridges, and sandbars affect patterns of wave refraction and height, coastal currents, and control sediment transport. These seabed anomalies indicate the availability and movement of sand within the nearshore environment, which may be directly related to the stability of the Cape Canaveral shoreline. Understanding the complex dynamics of the offshore bathymetry and associated sediment pathways can help identify current and future erosion vulnerabilities due to short-term (for example, hurricane and other extreme storms) and long-term (for example, sea-level rise) hazards.

  18. Toward better assessment of tornado potential in typhoons: Significance of considering entrainment effects for CAPE

    Science.gov (United States)

    Sueki, Kenta; Niino, Hiroshi

    2016-12-01

    The characteristics of typhoons that spawned tornadoes (tornadic typhoons: TTs) in Japan from 1991 to 2013 were investigated by composite analysis using the Japanese 55 year Reanalysis and compared with those of typhoons that did not spawn tornadoes (nontornadic typhoons: NTs). We found that convective available potential energy (CAPE), which considers the effects of entrainment (entraining CAPE: E-CAPE), and storm-relative environmental helicity (SREH) are significantly large in the northeast quadrant of TTs where tornadoes frequently occur and that E-CAPE and SREH in that quadrant for TTs are larger than those for NTs. On the other hand, ordinary CAPE without entrainment does not account for the spatial distribution of tornado occurrences nor does it distinguish TTs from NTs. E-CAPE is sensitive to humidity in the midtroposphere; thus, it is effective for detecting a conditionally unstable layer up to about 550 hPa, which is distinctive of TTs.

    Xavier Luffin

    2008-12-01

    Full Text Available In the context of the White and Christian-dominated Afrikaans language movements, followed by apartheid, little attention has been paid to an Afrikaans literary variety used among Muslim Cape Coloureds, a group often referred to as ‘Cape Malays’. Descending mainly from Asian slaves brought by the Verenigde Oost-Indische Compagnie (VOC, Dutch East India Company, and bearing the marks of cohabitation with non-Asian populations at the Cape, the Cape Malays at an early stage developed a distinct religious culture through their adherence to Islam, as well as a distinct Cape Dutch linguistic identity through their connections with the Dutch East Indies and the Islamic world. These cultural idiosyncrasies found expression in a local literature, religious and (more rarely secular, using as a medium a variety of Cape Dutch/Afrikaans written either in the Arabic alphabet or in the Roman alphabet.

    The Mars Exploration Rover Opportunity has recently completed a two year campaign studying Victoria Crater. The campaign culminated in a close approach of Cape Verde in order to acquire high resolution imagery of the exposed stratigraphy in the cliff face. The close approach to Cape Verde provided significant challenges for every subsystem of the rover as the rover needed to traverse difficult, uncharacterised terrain and approach a cliff face with the potential of blocking out solar energy and communications with Earth. In this paper we describe the strategic analyses performed by the science and engineering teams so that we could successfully achieve the science objectives while keeping the rover safe.

  5. The cone snails of Cape Verde: Marine endemism at a terrestrial scale

    Directory of Open Access Journals (Sweden)

    Howard Peters

    2016-07-01

    Full Text Available Cape Verde in the Eastern Atlantic is typical of many island groups in supporting a wealth of endemic species both terrestrial and marine. Marine gastropod molluscs of the genus Conus, commonly known as cone snails, occur in coastal tropical waters throughout the globe, but in Cape Verde their endemism reaches its apogee with 53 out of 56 species occurring nowhere else, the majority of which are restricted to single islands and frequently to single bays. However, Cape Verde is rapidly moving to a tourism-based economy with a projected boom in infrastructure development often coincidental with the shallow-water habitat of many range-restricted Conus. The conservation assessment of Conus to standards of the International Union for the Conservation of Nature (IUCN Red List of Endangered Species, found that 45.3% of 53 species assessed from Cape Verde are threatened or near-threatened with extinction compared to 7.4% of 579 species in the rest of the world. The only three Conus species globally assessed as Critically Endangered and on the cusp of extinction are all endemic to Cape Verde. Our analysis of Conus species distribution, together with spatial data of coastal protected areas and tourism development zones, identify important areas for future research and new marine protection. Our findings show that endemism with its associated risks for Conus in Cape Verde has worldwide parallels with many non-marine taxa, while our proposed strategy for Conus conservation extends beyond the confines of the country and this taxonomic group.

    The Cape mole rat Georychus capensis is a solitary subterranean rodent found in the western and southern Cape of South Africa. This approximately 200-gram bathyergid rodent shows a nocturnal circadian rhythm, but sleep in this species is yet to be investigated. Using telemetric recordings of the electroencephalogram (EEG) and electromyogram (EMG) in conjunction with video recordings, we were able to show that the Cape mole rat, like all other rodents, has sleep periods composed of both rapid eye movement (REM) and slow-wave (non-REM) sleep. These mole rats spent on average 15.4 h awake, 7.1 h in non-REM sleep and 1.5 h in REM sleep each day. Cape mole rats sleep substantially less than other similarly sized terrestrial rodents but have a similar percentage of total sleep time occupied by REM sleep. In addition, the duration of both non-REM and REM sleep episodes was markedly shorter in the Cape mole rat than has been observed in terrestrial rodents. Interestingly, these features (total sleep time and episode duration) are similar to those observed in another subterranean bathyergid mole rat, i.e. Fukomys mechowii. Thus, there appears to be a bathyergid type of sleep amongst the rodents that may be related to their environment and the effect of this on their circadian rhythm. Investigating further species of bathyergid mole rats may fully define the emerging picture of sleep in these subterranean African rodents. © 2016 S. Karger AG, Basel.

    Vascular wilt caused by Fusarium oxysporum is the most important disease in cape gooseberry (Physalis peruviana L.) in Colombia. The development of resistant cultivars is considered one of the most cost-effective means to reduce the impact of this disease. In order to do so, it is necessary to provide breeders with molecular markers and promising germplasm for introgression of different resistance loci as part of breeding schemes. Here we described an association mapping study in cape gooseberry with the goal to: (i) select promising materials for use in plant breeding and (ii) identify SNPs associated with the cape gooseberry resistance response to the F. oxysporum pathogen under greenhouse conditions, as potential markers for cape gooseberry breeding. We found a total of 21 accessions with different resistance responses within a diversity panel of 100 cape gooseberry accessions. A total of 60,663 SNPs were also identified within the same panel by means of GBS (Genotyping By Sequencing). Model-based population structure and neighbor-joining analyses showed three populations comprising the cape gooseberry panel. After correction for population structure and kinship, we identified SNPs markers associated with the resistance response against F. oxysporum. The identification of markers was based on common tags using the reference genomes of tomato and potato as well as the root/stem transcriptome of cape gooseberry. By comparing their location with the tomato genome, 16 SNPs were found in genes involved in defense/resistance response to pathogens, likewise when compared with the genome of potato, 12 markers were related. The work presented herein provides the first association mapping study in cape gooseberry showing both the identification of promising accessions with resistance response phenotypes and the identification of a set of SNP markers mapped to defense/resistance response genes of reference genomes. Thus, the work also provides new knowledge on candidate

    Ambient air is a core medium for monitoring of persistent organic pollutants (POPs) under the Stockholm Convention and is used in studies of global transports of POPs and their atmospheric sources and source regions. Still, data based on active air sampling remain scarce in many regions. The primary objectives of this study were to (i) monitor concentrations of selected POPs in air outside West Africa, and (ii) to evaluate potential atmospheric processes and source regions affecting measured concentrations. For this purpose, an active high-volume air sampler was installed on the Cape Verde Atmospheric Observatory at Cape Verde outside the coast of West Africa. Sampling commenced in May 2012 and 43 samples (24h sampling) were collected until June 2013. The samples were analyzed for selected polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), hexachlorobenzene (HCB) and chlordanes. The concentrations of these POPs at Cape Verde were generally low and comparable to remote sites in the Arctic for several compounds. Seasonal trends varied between compounds and concentrations exhibited strong temperature dependence for chlordanes. Our results indicate net volatilization from the Atlantic Ocean north of Cape Verde as sources of these POPs. Air mass back trajectories demonstrated that air masses measured at Cape Verde were generally transported from the Atlantic Ocean or the North African continent. Overall, the low concentrations in air at Cape Verde were likely explained by absence of major emissions in areas from which the air masses originated combined with depletion during long-range atmospheric transport due to enhanced degradation under tropical conditions (high temperatures and concentrations of hydroxyl radicals).

    Full Text Available The jurisdiction of Stellenbosch, located adjacent to, but outside of, the Cape Town metropolitan area in the Western Cape Province of South Africa, comprises over one thousand square kilometers of landscapes spanning: spectacular mountain wilderness areas; many productive rural valleys that are an integral part of the celebrated Cape Winelands; and a number of historic, characterful urban centres founded during the 17th century. Overall, this blend of domains attracts increasing numbers of tourists, while the places are also home to a growing population. The pressures for change and growth are significant: so is the need for appropriate policies and plans in the longer-term public interest. The authors report on a three-year project they are conducting for the local authority that focuses on the definition of the natural and cultural heritage and, in principle, on how development should be channelled.

    2018-06-01

    As part of an initiative to characterize viruses infecting Cape gooseberry in the province of Antioquia (Colombia), we report the genome sequence of a new member of the genus Ilarvirus (family Bromoviridae). This virus was identified in a Cape gooseberry plot in the municipality of Marinilla in a mixed infection with potato virus Y (PVY) as part of high-throughput sequencing initiative. Results were confirmed by nested RT-PCR and DAS-ELISA. Phylogenetic analysis suggested that the Cape gooseberry ilarvirus is a new member of subgroup 1 and it is most closely related to ageratum latent virus (AgLV). The name "Cape gooseberry ilarvirus 1" (CGIV-1) is proposed for this new ilarvirus.

    2017-12-01

    As the global urban population rapidly increases, many wild species lose habitat to human development. The Western Cape of South Africa contains one of Earth's 35 biodiversity hotspots, with remarkably high levels of species richness and endemism. Understanding the relationship between anthropogenic changes and key species in this region is crucial for conservation of its threatened ecosystems. The objective of this research was to investigate the effect that climate change and urbanization each have on habitat suitability of the Cape Vulture. This research utilized NASA satellite data and crowdsourced species sightings to model past, current, and future habitat suitability for this key species in the Western Cape. Data used from NASA Earth Observations included: Landsat 8- derived Land Cover, Modis Land Surface Temperature, Digital Elevation Models from the Shuttle Radar Topography Mission, and precipitation data which integrated in-situ stations with Infrared data. Species observations were sourced from the Global Biodiversity Information Facility online database. A geospatial modelling framework was used to generate maps of present, past and future suitable habitats for analysis and comparison. Changes in precipitation and temperature may be a factor in the extreme loss of habitat since 1995, and predict even more drastic loss in the future. This research provides insights on anthropogenic effects on a species' range which may be used to inform discussions of conservation as an element of environmentally sustainable development.

    1996-01-01

    A discussion of the ozone and radon variations at Cape Grim, Tasmania, and their interdependence is presented. The use of radon concentration as a criterion for baseline conditions ( - 3) results in a baseline data set that has a smaller range of concentrations within each month than that obtained using wind speed and direction as baseline criteria. The passage of cold fronts at Cape Grim is associated with a change in air flow from the continent to the Southern Ocean. Comparison of radon, wind direction and ozone during these events indicates that continental air continues arriving at Cape Grim for several hours after passage of the front and the establishment of the air flow from the baseline sector. This confirms that use of the speed and direction is not necessarily a good method of defining baseline conditions for ozone. When air comes to Cape Grim form over the Tasmanian land surface during those times of the year when (due to solar radiation and temperature) the probability of ozone production is low, the ozone and radon concentrations observed are negatively correlated. A simple model of ozone destruction at the Earth's surface and radon emission from the surface quantitatively describes these observations. (author). 1 tab., 5 figs., 6 refs

    Prostate cancer (PCa) was the fifth most common cancer overall in the world. More than 80% of patients died from PCa developed bone metastases. Caffeic acid phenethyl ester (CAPE) is a main bioactive component of honeybee hive propolis. Transwell and wound healing assays demonstrated that CAPE treatment suppressed the migration and invasion of PC-3 and DU-145 PCa cells. Gelatin zymography and Western blotting indicated that CAPE treatment reduced the abundance and activity of MMP-9 and MMP-2. Analysis using Micro-Western Array (MWA), a high-throughput antibody-based proteomics platform with 264 antibodies detecting signaling proteins involved in important pathways indicated that CAPE treatment induced receptor tyrosine kinase-like orphan receptor 2 (ROR2) in non-canonical Wnt signaling pathway but suppressed abundance of β-catenin, NF-κB activity, PI3K-Akt signaling, and epithelial-mesenchymal transition (EMT). Overexpression or knockdown of ROR2 suppressed or enhanced cell migration of PC-3 cells, respectively. TCF-LEF promoter binding assay revealed that CAPE treatment reduced canonical Wnt signaling. Intraperitoneal injection of CAPE reduced the metastasis of PC-3 xenografts in tail vein injection nude mice model. Immunohistochemical staining demonstrated that CAPE treatment increased abundance of ROR2 and Wnt5a but decreased protein expression of Ki67, Frizzle 4, NF-κB p65, MMP-9, Snail, β-catenin, and phosphorylation of IκBα. Clinical evidences suggested that genes affected by CAPE treatment (CTNNB1, RELA, FZD5, DVL3, MAPK9, SNAl1, ROR2, SMAD4, NFKBIA, DUSP6, and PLCB3) correlate with the aggressiveness of PCa. Our study suggested that CAPE may be a potential therapeutic agent for patients with advanced PCa.

    The bound volatile fraction of cape gooseberry (Physalis peruviana L.) fruit harvested in Colombia has been examined by HRGC and HRGC-MS after enzymatic hydrolysis using a nonselective pectinase (Rohapect D5L). Forty bound volatiles could be identified, with 21 of them being reported for the first time in cape gooseberry. After preparative isolation of the glycosidic precursors on XAD-2 resin, purification by multilayer coil countercurrent chromatography and HPLC of the peracetylated glycosides were carried out. Structure elucidation by NMR, ESI-MS/MS, and optical rotation enabled the identification of (1S,2S)-1-phenylpropane-1,2-diol 2-O-beta-D-glucopyranoside (1) and p-menth-4(8)-ene-1,2-diol 1-O-alpha-L-arabinopyranosyl-(1-6)-beta-D-glucopyranoside (2). Both glycosides have been identified for the first time in nature. They could be considered as immediate precursors of 1-phenylpropane-1,2-diol and p-menth-4(8)-ene-1,2-diol, typical volatiles found in the fruit of cape gooseberry.

    Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

    The Chariot site is located in the Ogotoruk Valley in the Cape Thompson region of northwest Alaska. Project Chariot was part of the Plowshare Program, created in 1957 by the US Atomic Energy Commission (AEC), a predecessor agency of the US Department of Energy (DOE), to study peaceful uses for atomic energy. Project Chariot began in 1958 when a scientific field team chose Cape Thompson as a potential site to excavate a harbor using a series of nuclear explosions. AEC, with assistance from other agencies, conducted more than 40 pretest bioenvironmental studies of the Cape Thompson area between 1959 and 1962; however, the Plowshare Program work at the Project Chariot site (Figure 1) was cancelled because of strong public opposition [1]. No nuclear explosions were ever conducted at the site.

  6. Stable carbon isotopic assessment of prehistoric diets in the south-western Cape, Cape Town, South Africa

    Energy Technology Data Exchange (ETDEWEB)

    Sealy, J C

    1984-01-01

    This thesis consists of a stable carbon isotopic assessment of the diets of the Holocene human inhabitants of the south-western Cape, South-Africa. Samples of the foods these people ate were collected from each of the four major physiographic zones in the area, and their /sup 13/C//sup 12/C ratios measured. A total of more than 200 such analyses enabled the estimation of the average delta /sup 13/C values of prehistoric human diets in each zone. This information is used to interpret delta /sup 13/C measurements on a series of archaeological human skeletons. The results are consistent with a model of prehistoric subsistence behaviour in which people living at the coast made intensive use of marine food resources throughout the Holocene, consuming such a large proportion of these foods that they must have spent much, if not all of their time at the coast. Inland skeletons reflect an almost entirely terrestrial diet. These results contradict hypotheses about seasonal population movements between the coast and the interior generated from excavated archaeological material. Considerable changes in many of our current views of the Late Stone Age of the south-western Cape will have to be made in order to accommodate these data.

    2013-01-01

    Full Text Available Research has shown that the backpacker market is one of the tourism markets that economically benefit local communities than the conventional market or mass tourists. The purpose of the study was to examine the motivations of backpackers in the Cape Coast-Elmina conurbation, Ghana. Questionnaire was used to collect data from 184 backpackers in Cape Coast and Elmina. Factor Analysis and some descriptive statistical analysis were employed in presenting the report. The study revealed that backpackers, who visited the Cape Coast-Elmina conurbation, were mostly young international students, most of whom were of European origin. Using the push-pull theory by Dann (1981, 6 main orthogonal push-pull related factors, including historical/cultural attractions, service delivery, ecological attractions, heritage, escape, and adventure were found to have explained backpackers’ motivations for travelling. It is recommended that local travel intermediaries focus attention on packaging tailored tours that will sell the country’s historical, cultural and ecological attractions to backpackers. Secondly, the Ghana Tourism Authority (GTA should formally recognize and incorporate hostel facilities into the accommodation sub-sector, and regularize monitoring activities in these facilities in order to maintain quality standards for patronage by backpackers.

  20. Can Cape Town's unique biodiversity be saved? Balancing conservation imperatives and development needs

    Directory of Open Access Journals (Sweden)

    Patricia M. Holmes

    2012-06-01

    Full Text Available Cape Town is an urban hotspot within the Cape Floristic Region global biodiversity hotspot. This city of 2,460 km² encompasses four local centers of fynbos plant endemism, 19 national terrestrial vegetation types (six endemic to the city, wetland and coastal ecosystems, and 190 endemic plant species. Biodiversity in the lowlands is under threat of extinction as a result of habitat loss to agriculture, urban development, mining, and degradation by invasive alien plants. Cape Town's population is 3.7 million, increasing by an estimated 55,000 people/yr, which puts pressure on biodiversity remnants for development. South Africa is a signatory to international instruments to reduce biodiversity loss and has a good legislative and policy framework to conserve biodiversity, yet implementation actions are slow, with limited national and provincial support to conserve Cape Town's unique and irreplaceable biodiversity. The lack-of-action problem is two-fold: national government is slow to implement the policies developed to realize the international instruments it has signed, with conservation initiatives inadequately funded; and local governments are not yet recognized as important implementation partners. A further problem is created by conflicting policies such as the national housing policy that contributes to urban sprawl and loss of critical biodiversity areas. The City's Biodiversity Management Branch, with partners, is making some headway at implementation, but stronger political commitment is needed at all levels of government. Our objective is to improve the status and management of biodiversity in existing conservation areas through the statutory proclamation process and management effectiveness monitoring, respectively, and to secure priority areas of the BioNet, Cape Town's systematic biodiversity plan. The most important tools for the latter are incorporating the BioNet plan into City spatial plans; communication, education, and public

    This research is an examination of the relationship between loneliness and a number of psychosocial variables (e.g., affective state, cultural issues, gender, age) among adolescents and young adults from Cape Verde and Portugal. Two studies are presented. The participants in the first study were 285 adolescents from Cape Verde and 202 from Portugal, and in the second study there were 134 college students from Cape Verde and 112 from Portugal. The following instruments were administered to all the participants in both studies: The Revised UCLA Loneliness Scale (D. Russell, L. Peplau, & C. Cutrona, 1980), the Neuroticism Scale (J. Barros, 1999), the Optimism Scale (J. Barros, 1998), the Social Anxiety subscale (A. Fenigstein, M. Scheier, & A. Buss, 1975), and the Satisfaction With Life Scale (E. Diener, R. Emmons, R. Larsen, & S. Griffin, 1985). No ethnic or gender differences were found for loneliness between the two groups. For both groups, the most prominent predictors of loneliness were neuroticism and dissatisfaction with life. However, as expected, the adolescent group recorded higher scores for loneliness than did the college students.

    Cape gooseberry (Physalis peruviana) is an exotic fruit highly valued, however it is a very rich source of polyphenol oxidase (PPO). In this study, Cape gooseberry PPO was isolated and biochemically characterized. The enzyme was extracted and purified using acetone and aqueous two-phase systems. The data indicated that PPO had the highest substrate affinity for chlorogenic acid, 4-methylcatechol and catechol. Chlorogenic acid was the most suitable substrate (Km=0.56±0.07 mM and Vmax=53.15±2.03 UPPO mL(-1) min(-1)). The optimal pH values were 5.5 for catechol and 4-methylcatechol and 5.0 for chlorogenic acid. Optimal temperatures were 40°C for catechol, 25°C for 4-methylcatechol and 20°C for chlorogenic acid. In inhibition tests, the most potent inhibitor was found to be ascorbic acid followed by L-cysteine and quercetin. This study shows possible treatments that can be implemented during the processing of Cape gooseberry fruits to prevent browning. Copyright © 2015 Elsevier Ltd. All rights reserved.

  3. Differences in CAPE between wet and dry spells of the monsoon over the southeastern peninsular India

    Science.gov (United States)

    Mohan, T. S.; Rao, T. N.; Rajeevan, M.

    2018-03-01

    In the present research we explored the variability of convective available potential energy (CAPE) during wet and dry spells over southeast India. Comparison between India Meteorological Department (IMD) observations and reanalysis products (NCEP, ERA-interim, and MERRA) reconfirms that gridded data sets can be utilized to fill the void of observations. Later, GPS radiosonde measurements made at Gadanki (13.5 N, 79.2 E) Andre analysis output are utilized to address key scientific issues related to CAPE over the southeastern peninsular region. They are: (1) How does CAPE vary between different spells of the Indian summer monsoon (i.e., from wet to dry spell)? (2) Does differences in CAPE and in the vertical structure of buoyancy between spells are localized features over Gadanki or observed all over southeastern peninsular region? (3) What physical/dynamical processes are responsible for the differences in CAPE between spells and how do they affect the convection growth in dry spell? Interestingly, CAPE is higher in wet spell than in dry spell, in contrast to the observations made elsewhere over land and warm oceans. Similar feature (high CAPE in wet spell) is observed at all grid points in the southeastern peninsular India. Furthermore, vertical buoyancy profiles show only one peak in the middle-upper troposphere in wet spell, while two peaks are observed in most of the profiles (66%) in dry spell over the entire study region in all the reanalysis products. Plausible mechanisms are discussed for the observed CAPE differences. They are, among others, timing of sounding with reference to rain occurrence, rapid buildup of surface instabilities, moistening of lower troposphere by evaporation of the surface moisture in wet spell, enhanced low-level moisture convergence, evaporation of rain in relatively warm and dry atmosphere, and reduction of positive buoyancy in dry spell. The omnipresence of stable layers and strong and deep shear in the presence of weak updrafts

    Sugar cane spirits are some of the most popular alcoholic beverages consumed in Cape Verde. The sugar cane spirit industry in Cape Verde is based mainly on archaic practices that operate without supervision and without efficient control of the production process. The objective of this work was to evaluate samples of industrial and alembic sugar cane spirits from Cape Verde and Ceará, Brazil using principal component analysis. Thirty-two samples of spirits were analyzed, twenty from regions of the islands of Cape Verde and twelve from Ceará, Brazil. Of the samples obtained from Ceará, Brazil seven are alembic and five are industrial spirits. The components analyzed in these studies included the following: volatile organic compounds (n-propanol, isobutanol, isoamylic, higher alcohols, alcoholic grade, acetaldehyde, acetic acid, acetate); copper; and sulfates.

  7. The need for nuclear power at the Cape

    International Nuclear Information System (INIS)

    Myburgh, R.P.A.

    1980-01-01

    The paper gives an indication of the growth of electrical power usage in the Western Cape. In planning to increase the supply of electricity to the Western Cape several factors had to be taken into account. It appeared that the cost to construct a nuclear power plant and the generation of nuclear power compares well with other methods of power generation. Before the construction of Koeberg was started, extensive investigations were undertaken to find a suitable site. Factors taken into account in the investigation included population density, geology and transport facilities. The safety of nuclear power plants are discussed. Mention is made of safeguards inherent in the design of a nuclear power plant. It appears that the possibility of radioactive effluent reaching the atmosphere as result of an accident or malfunctioning of a nuclear plant is very small as there are various safety systems designed to prevent it. Radioactive waste disposal is also discussed

  8. CAPES: Unsupervised Storage Performance Tuning Using Neural Network-Based Deep Reinforcement Learning

    CERN Multimedia

    CERN. Geneva

    2017-01-01

    Parameter tuning is an important task of storage performance optimization. Current practice usually involves numerous tweak-benchmark cycles that are slow and costly. To address this issue, we developed CAPES, a model-less deep reinforcement learning-based unsupervised parameter tuning system driven by a deep neural network (DNN). It is designed to nd the optimal values of tunable parameters in computer systems, from a simple client-server system to a large data center, where human tuning can be costly and often cannot achieve optimal performance. CAPES takes periodic measurements of a target computer system’s state, and trains a DNN which uses Q-learning to suggest changes to the system’s current parameter values. CAPES is minimally intrusive, and can be deployed into a production system to collect training data and suggest tuning actions during the system’s daily operation. Evaluation of a prototype on a Lustre system demonstrates an increase in I/O throughput up to 45% at saturation point. About the...

    Highlights: • The design of 2 off-grid electrification projects in Cape Verde is developed. • Configurations with hybrid renewable energy systems and micro-grids are considered. • A detailed micro-scale wind resource assessment is carried out. • An optimization model is used in order to support the design. • The proposed system is economically beneficial in comparison with diesel generation. - Abstract: Even though Cape Verde has high wind and solar energy resources, the conventional strategy for increasing access to electricity in isolated rural areas is by centralized microgrids with diesel generators. In this study, the design of 2 off-grid electrification projects based on hybrid wind–photovoltaic systems in Cape Verde is developed and analyzed. The design considers some significant novelty features in comparison with previous studies. First a detailed wind resource assessment is carried out combining meso-scale wind climate data and a specialized micro-scale wind flow model. Then a mathematical model is used for the design of off-grid projects considering a combination of individual systems and microgrids. In this study, locations far from the demand points are also considered as possible generation points. Various design configurations are analyzed and compared. The proposed configurations exploit the highest wind potential areas and are economically beneficial in comparison with diesel generator systems

  10. Paper trail: Chasing the Chinese in the Cape (1904-1933

    Directory of Open Access Journals (Sweden)

    Karen L. Harris

    Full Text Available The Chinese Exclusion Act passed by the Cape parliament in 1904 was one of the first pieces of legislation promulgated in the southern region of Africa where a particular 'racial group' was singled out, documented and discriminated against. Although it had trans-oceanic antecedents and tapped into this global anti-Chinese sentiment, unlike the Chinese exclusion legislation elsewhere, the Cape exclusion legislation targeted the entire Chinese 'race'. This article proposes to trace the application of this unwieldy registration system and show how the small Chinese community was registered, identified, monitored and hounded both on paper and on the ground until well after the repeal of the Act three decades later. Through an analysis of these paper records, the article intends to elucidate the nature of this imposition and consider what they tell us of the Chinese it was imposed upon and how they responded. It also proposes that, while the Act was formulated for exclusion, ironically for just under 1,500 of the Chinese resident at the colonial Cape it eventually warranted a double inclusion, one in the form of a certificate of exemption and hence domicile - albeit with perpetual surveillance and scrutiny - and the other as part of the archived historic record.

  13. Youth ministry as an agency of youth development for the vulnerable youth of the Cape Flats

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Religiosity has a profound role and influence on youth development within a community. Religiosity promotes risk reduction and positive moral characteristics and thus remains an avenue of opportunity for transformation in considering the lived experiences of vulnerable young people living on the Cape Flats in the Western Cape, South Africa. The Cape Flats is an area that is overwhelmed with unemployment, poverty, gang violence, chemical substance abuse and a general societal abandonment of young people. It is out of dire hopelessness that a meaningful relationship with God can be experienced by youth. The Cape Flats is, therefore, a fertile space for an intervention of religiosity. This article will research how the agency of youth ministry as a positive youth development can assist in youth development within a community in tension like that of the Cape Flats. While youth development is a broad category for consideration and research, this article will primarily focus on identity formation of young people, in particular, the vulnerable youth living on the Cape Flats.Intradisciplinary and/or interdisciplinary implications: The agency of youth ministry, in an evangelical epistemology, should seek to address the influencers on adolescent identity formation, as one�s identity has a direct bearing on faith formation. The potential outcome of the article would allow the youth ministry to take serious the impact of the lived realities of youth and adjust their programmatic designs and outcomes, in relation to youth faith formation.

    2012-01-01

    Full Text Available Sugar cane spirits are some of the most popular alcoholic beverages consumed in Cape Verde. The sugar cane spirit industry in Cape Verde is based mainly on archaic practices that operate without supervision and without efficient control of the production process. The objective of this work was to evaluate samples of industrial and alembic sugar cane spirits from Cape Verde and Ceará, Brazil using principal component analysis. Thirty-two samples of spirits were analyzed, twenty from regions of the islands of Cape Verde and twelve from Ceará, Brazil. Of the samples obtained from Ceará, Brazil seven are alembic and five are industrial spirits. The components analyzed in these studies included the following: volatile organic compounds (n-propanol, isobutanol, isoamylic, higher alcohols, alcoholic grade, acetaldehyde, acetic acid, acetate; copper; and sulfates.

  16. Decontamination of Cape Arza (Montenegro) from depleted Uranium

    International Nuclear Information System (INIS)

    Vukotich, P.; Kovachevich, M.; Vasich, V.; Ristich, N.

    2002-01-01

    On May 30, 1999, NATO A-10 aircrafts attacked Cape Arza, a very attractive touring area on peninsula Lustica, at the entrance of Boka Kotorska Bay, in Montenegro. They fired anti-armour rounds with penetrators made of depleted uranium. Such an armour-penetrating round has a length of 173 mm and a diameter of 30 mm. The bullet has an aluminium case (jacket) and inside it a conical DU penetrator. The length of the penetrator itself is 95 mm, and the diameter of its base is 16 mm. The penetrator weight is 292 g. According to the data reported by NATO (NATO, 2001), the total number of rounds fired against Cape Arza was 480. As to the data on combat mix of the A-10 aircraft gun, 300 (UNEP, 2001) or 400 (UNEP, 2001; FAS) of these rounds where with DU penetrators, and the rest with a classical charge. This means that Cape Arza was contaminated with 90 or 120 kg of DU, or with a radioactivity of (3.5 - 4.7) · 10 9 Bq. Depleted uranium is a waste product of the process of uranium enrichment in 2 35U isotope, for use in nuclear reactors or in nuclear weapons. The isotopic composition of depleted uranium is (Harley et al., 1999): (99.7 - 99.8) % of 2 38U , (0.2 - 0.3) % of 2 35U , 0.001 % of 2 34U , and only traces of 2 34T h, 2 34P a and 2 31T h. If traces of the isotopes 2 36U , 2 39P u and 2 40P u are also present, as it is the case with DU from Cape Arza (UNEP, 2002), the depleted uranium is obtained by reprocessing of spent nuclear reactor fuel. The activity concentration of depleted uranium is 39.42 · 10 6 Bq/kg. Most of it comes from 2 38U and its decay products 2 34T h and 2 34P a which are in radioactive equilibrium (12.27 · 10 6 Bq/kg per each of them), and the less part from 2 35U and 2 31T h (0.16 · 10 6 Bq/kg per each) (UNEP, 1999), while the activity concentration of 2 36U , 2 39P u and 2 40P u is below 100 Bq/kg (UNEP, 2001)

    2013-01-01

    The objectives of this study were to (1) conduct an elemental characterization of airborne particles sampled in Cape Verde and (2) assess the influence of Sahara desert on local suspended particles. Particulate matter (PM(10)) was collected in Praia city (14°94'N; 23°49'W) with a low-volume sampler in order to characterize its chemical composition by k0-INAA. The filter samples were first weighed and subsequently irradiated at the Portuguese Research Reactor. Results showed that PM(10) concentrations in Cape Verde markedly exceeded the health-based air quality standards defined by the European Union (EU), World Health Organization (WHO), and U.S. Environmental Protection Agency (EPA), in part due to the influence of Sahara dust transport. The PM(10) composition was characterized essentially by high concentrations of elements originating from the soil (K, Sm, Co, Fe, Sc, Rb, Cr, Ce, and Ba) and sea (Na), and low concentrations of anthropogenic elements (As, Zn, and Sb). In addition, the high concentrations of PM measured in Cape Verde suggest that health of the population may be less affected compared with other sites where PM(10) concentrations are lower but more enriched with toxic elements.

  4. The health benefits of attaining and strengthening air quality standards in Cape Town

    Directory of Open Access Journals (Sweden)

    Samantha Keen

    2016-12-01

    Full Text Available The link between pollution and poor health and mortality has been established globally. Developing countries carry most of the burden of ill health from air pollution, and urban centres like the City of Cape Town even more so. Effective air quality management to protect human health relies on the attainment of air quality standards. This study uses the Benefits Mapping and Analysis Program (BenMAP along with a locally derived exposure-response function and air quality monitor data to investigate whether the consistent attainment of current or more stringent air quality standards would avoid loss of life. The results show that attaining the PM10 24-hour mean South Africa National Standard limit and the PM10 and SO2 24-hour mean World Health Organisation guidelines in Cape Town reduces levels of pollutants and does reduce excess risk of mortality in Cape Town.

  6. A colostrum trypsin inhibitor gene expressed in the Cape fur seal mammary gland during lactation.

    Pharo, Elizabeth A; Cane, Kylie N; McCoey, Julia; Buckle, Ashley M; Oosthuizen, W H; Guinet, Christophe; Arnould, John P Y

    2016-03-01

    The colostrum trypsin inhibitor (CTI) gene and transcript were cloned from the Cape fur seal mammary gland and CTI identified by in silico analysis of the Pacific walrus and polar bear genomes (Order Carnivora), and in marine and terrestrial mammals of the Orders Cetartiodactyla (yak, whales, camel) and Perissodactyla (white rhinoceros). Unexpectedly, Weddell seal CTI was predicted to be a pseudogene. Cape fur seal CTI was expressed in the mammary gland of a pregnant multiparous seal, but not in a seal in its first pregnancy. While bovine CTI is expressed for 24-48 h postpartum (pp) and secreted in colostrum only, Cape fur seal CTI was detected for at least 2-3 months pp while the mother was suckling its young on-shore. Furthermore, CTI was expressed in the mammary gland of only one of the lactating seals that was foraging at-sea. The expression of β-casein (CSN2) and β-lactoglobulin II (LGB2), but not CTI in the second lactating seal foraging at-sea suggested that CTI may be intermittently expressed during lactation. Cape fur seal and walrus CTI encode putative small, secreted, N-glycosylated proteins with a single Kunitz/bovine pancreatic trypsin inhibitor (BPTI) domain indicative of serine protease inhibition. Mature Cape fur seal CTI shares 92% sequence identity with Pacific walrus CTI, but only 35% identity with BPTI. Structural homology modelling of Cape fur seal CTI and Pacific walrus trypsin based on the model of the second Kunitz domain of human tissue factor pathway inhibitor (TFPI) and porcine trypsin (Protein Data Bank: 1TFX) confirmed that CTI inhibits trypsin in a canonical fashion. Therefore, pinniped CTI may be critical for preventing the proteolytic degradation of immunoglobulins that are passively transferred from mother to young via colostrum and milk.

  12. Spiders are Mammals: Direct Instruction in Cape York

    Directory of Open Access Journals (Sweden)

    Louise Dow

    2011-12-01

    Full Text Available In 2010, SRA Direct Instructioni was introduced across the curriculum in two remote Cape York schools, as a key aspect of social and welfare reform. There is national political interest in these reforms, which link welfare policy to State primary school education conceived as basic skills training. Reflecting the political interest, national newspapers ran the story that Direct Instruction had provided almost miraculous results after 17 weeks (Devine 2010a. Alternative approaches to literacy development in Indigenous education did not get the same sort of media attention. Noel Pearson provides the intellectual basis for Cape York social reforms, through his writing, political advocacy and leadership of organisations involved in the reforms. His ultimate goal is successful mainstream education leading to economic integration, where young people are „completely fluent in their own culture and the wider culture‟ (Pearson 2009:57. The question posed by this vision is „What kind of education can produce these flexible, bicultural, working people who keep their traditions alive?‟

    2012-10-22

    Two concomitant dengue 3 (DEN-3) epidemics occurred in Cape Verde Archipelago and Senegal between September and October 2009. Aedes aegypti was identified as the vector of these epidemics as several DEN-3 virus strains were isolated from this species in both countries. The susceptibility to pyrethroids, organochlorine, organophosphates and carbamate was investigated in two field strains of Aedes aegypti from both countries using WHO diagnostic bioassay kits in order to monitor their the current status of insecticide susceptibility. The two tested strains were highly resistant to DDT. The Cape Verde strain was found to be susceptible to all others tested insecticides except for propoxur 0.1%, which needs further investigation. The Dakar strain was susceptible to fenitrothion 1% and permethrin 0.75%, but displayed reduced susceptibility to deltamethrin, lambda-cyhalothrin and propoxur. As base-line results, our observations stress a careful management of insecticide use for the control of Ae. aegypti. Indeed, they indicate that DDT is no longer efficient for the control of Ae. aegypti populations in Cape Verde and Dakar and further suggest a thorough follow-up of propoxur susceptibility status in both sites and that of deltamethrin and lambda-cyhalothrin in Ae. aegypti populations in Dakar. Thus, regular monitoring of susceptibility is greatly needed as well as the knowing if this observed resistance/susceptibility is focal or not and for observed resistance, the use of biochemical methods is needed with detailed comparison of resistance levels over a large geographic area.

    Background Major health sector reform and the need for baseline measures of performance to determine impact. Aim Baseline audit of primary healthcare (PHC) performance. Setting Cape Town and Cape Winelands (rural) PHC facilities (PCFs) in Western Cape Province, South Africa. Method The South African cross-culturally validated ZA PCAT to audit PHC performance on 11 subdomains associated with improved health and reduced costs. Adult PCF users systematically sampled. All full-time doctors and nurse practitioners in PCFs sampled and all PCF managers in sub-districts sampled invited into the study. Results Data from 1432 users, 100 clinicians and 64 managers from 13 PCFs in 10 sub-districts analysed (figures show stakeholder percentages scoring subdomain performance ‘acceptable to good’). 11.5% users scored access ‘acceptable to good’; community orientation and comprehensive services provided 20.8% and 39.9%, respectively. Total PHC score for users 50.2%; for managers and practitioners 82.8% and 88.0%, respectively. Among practitioners access was lowest (33.3%); PHC team (98.0%) and comprehensive services available (100.0%) highest. Among managers, access (13.5%) and family centredness (45.6%) are lowest; PHC team (85.9%) and comprehensive services available (90.6%) highest. Managers scored access, family centredness and cultural competence significantly lower than practitioners. Users scored comprehensive services available, comprehensive services provided and community orientation significantly lower than practitioners and managers. Conclusion Gaps between users’ experience and providers’ assessments of PHC performance are identified. Features that need strengthening and alignment with best practice, provincial and national, and health policies are highlighted with implications for practitioner and manager training, health policy, and research.

    This article describes the Ilita Labantu (IL) group in South Africa, that is working to reduce child abuse and violence against women. The group started in 1989, with the aim of reducing child rape and sexual assaults in five townships in Cape Town. Child rape is perpetuated by myths sustained by witch doctors and indigenous medicine that promote child rape as a cure-all for symptoms ranging from poverty to AIDS. IL has four satellite groups that educate rape and abuse victims and potential victims. It is assumed that girls are potential victims because of their early unawareness that gender is tied to some patterns of behavior. IL trained mass media groups to educate the general public. IL distributes public information materials on how to identify domestic violence and abuse and how to identify potential rapists within households. Materials are distributed to individuals in community programs and in training programs. Child survivors make presentations in playgroups in a nonthreatening way. IL interacts with courts of law, police stations, hospitals, and schools. The group refers 25-35 cases per day. The group is working on setting up private rooms in police stations where rape victims can make confidential complaints without public attention. IL also works to promote the use of alternative strategies for solving family conflicts.

    One outgrowth of the Convection and Precipitation/Electrification (CaPE) experiment that took place in central Florida during July and August 1991 was the creation of the CaPE Hydrometeorology Project (CHymP). The principal goal of this project is to investigate the daily water cycle of the CaPE experimental area by analyzing the numerous land and atmosphere in situ and remotely sensed data sets that were generated during the 40-days of observations. The water cycle comprises the atmospheric branch. In turn, the atmospheric branch comprises precipitation leaving the base of the atmospheric volume under study, evaporation and transpiration entering the base, the net horizontal fluxes of water vapor and cloud water through the volume and the conversion of water vapor to cloud water and vice-versa. The sum of these components results in a time rate of change in the water and liquid water (or ice) content of the atmospheric volume. The components of the land branch are precipitation input to and evaporation and transpiration output from the surface, net horizontal fluxes of surface and subsurface water, the sum of which results in a time rate of change in surface and subsurface water mass. The objective of CHymP is to estimate these components in order to determine the daily water budget for a selected area within the CaPE domain. This work began in earnest in the summer of 1992 and continues. Even estimating all the budget components for one day is a complex and time consuming task. The discussions below provides a short summary of the rainfall quality assessment procedures followed by a plan for estimating the horizontal moisture flux.

  19. Quantifying morphological changes of cape-related shoals

    The rising demand for marine resources has motivated the study of inner shelf transport processes, especially in locations with highly-developed coastlines, endangered-species habitats, and valuable economic resources. These characteristics are found at Cape Canaveral shoals, on the Florida Atlantic coast, where transport dynamics and morphological evolution are not well understood. To study morphological changes at these shoals, two sets of paired upward- and downward-pointing acoustic Doppler current profilers (ADCPs) were deployed in winter 2015-2016. One set was deployed at the inner swale of Shoal E, 20 km southeast of the cape tip in 13 m depth, while the other set was located at the edge of Southeast shoal in 5 m deep. Upward-pointing velocity profiles and suspended particle concentrations were implemented in the Exner equation to quantify instantaneous rates of change in bed elevation. This computation includes changes in sediment concentration and the advection of suspended particles, but does not account for spatial gradients in bed-load fluxes and water velocities. The results of the computation were then compared to bed change rates measured directly by the downward-pointing ADCPs. At the easternmost ridge, quantified bed elevation change rates ranged from -7×10-7 to 4×10-7 m/s, and those at the inner swale ranged from -4×10-7 to 8×10-7 m/s. These values were two orders of magnitude smaller than rates measured by downward-pointing ADCPs. Moreover, the cumulative changes were two orders of magnitude larger at the ridge (-0.33 m, downward, and -0.13, m upward) than at the inner swale (cf. -6×10-3 m, downward, and 3×10-3 m, upward). These values suggest that bedform migration may be occurring at the ridge, that suspended sediments account for up to 30% of total bed changes, and that gradients in bed-load fluxes exert control on morphological change over the shoals. Despite uncertainties related to the ADCP-derived sediment concentrations, these

    Full Text Available Toxoplasmosis was investigated in an eastern grey kangaroo, Macropus giganteus, and four cape hyraxes, Procavia capensis, in a Japanese zoo. Clinically, the kangaroo showed neurological signs, emaciation, diarrhea, elevated AST and CK, and subjected to coma before death. One young cape hyrax had severe anorexia, while the other three died without exhibiting clinical signs. Grossly, lungs of the kangaroo were dark red in color, while hyraxes, besides, showed hepatic multifocal white foci, and intestinal multifocal hemorrhages. Histologically, the kangaroo had frequent Toxoplasma gondii pseudocysts in brain, heart and skeletal muscles. All hyraxes had multifocal necrosis with cysts containing numerous bradyzoites in liver and spleen, along with necrotic gastroenteritis and intestinal hemorrhages. Immunohistochemically, cysts showed positive reaction to anti-T. gondii antibodies. These findings indicate possible outbreaks of toxoplasmosis in eastern grey kangaroos and cape hyraxes, zoo habitants; therefore, they could be susceptible intermediate hosts for T. gondii in terms of zoonosis. This is the first report of toxoplasmosis in eastern grey kangaroos and cape hyraxes in Japanese zoos.

    The human immunodeficiency virus type 1 (HIV-1) subtype G is the most prevalent and second most prevalent HIV-1 clade in Cape Verde and Portugal, respectively; but there is no information about the origin and spatiotemporal dispersal pattern of this HIV-1 clade circulating in those countries. To this end, we used Maximum Likelihood and Bayesian coalescent-based methods to analyze a collection of 578 HIV-1 subtype G pol sequences sampled throughout Portugal, Cape Verde and 11 other countries from West and Central Africa over a period of 22 years (1992 to 2013). Our analyses indicate that most subtype G sequences from Cape Verde (80%) and Portugal (95%) branched together in a distinct monophyletic cluster (here called G(CV-PT)). The G(CV-PT) clade probably emerged after a single migration of the virus out of Central Africa into Cape Verde between the late 1970s and the middle 1980s, followed by a rapid dissemination to Portugal a couple of years later. Reconstruction of the demographic history of the G(CV-PT) clade circulating in Cape Verde and Portugal indicates that this viral clade displayed an initial phase of exponential growth during the 1980s and 1990s, followed by a decline in growth rate since the early 2000s. Our data also indicate that during the exponential growth phase the G(CV-PT) clade recombined with a preexisting subtype B viral strain circulating in Portugal, originating the CRF14_BG clade that was later disseminated to Spain and Cape Verde. Historical and recent human population movements between Angola, Cape Verde and Portugal probably played a key role in the origin and dispersal of the G(CV-PT )and CRF14_BG clades.

    Full Text Available Cape snoek (Thyrsites atun is an important source of protein for people in South Africa; however, nutritional information thereof is limited. The proximate and fatty acid compositions of raw and cooked (80 °C snoek muscles were determined according to official AOAC methods. The mean moisture, ash, total lipids and protein for raw snoek were 72.8±1.86%, 1.3±0.09%, 4.0±1.16 and 21.5±1.35%, respectively. Cape snoek is very high in palmitic acid (24.65±1.43%, oleic acid (18.21±2.64%, eicosapentaenoic acid (EPA, 9.11±2.06% and docosahexaenoic acid (DHA, 19.70±3.25%. With the exception of total lipids, cooking significantly reduced moisture (69.40±2.03% and ash (1.12±0.12%, and increased protein (24.47±1.39% content. It is concluded that Cape snoek is very high in protein and can be classified as a low-fat fish which is rich in EPA and DHA.

    2017-04-01

    The interest of geoscientists in (geo)ethical aspects of geoscience knowledge, education, research and practice is rising and today geoethics has a significant visibility. This prominence is the result of hard work done in the last 4 years by the IAPG - International Association for Promoting Geoethics (http://www.geoethics.org), a not-for-profit, multidisciplinary, scientific network (with more than 1350 members in 107 countries) established for widening the discussion and creating awareness about problems of ethics applied to the geosciences. IAPG has produced a strong conceptual substratum on which to base the future development of geoethics, by clarifying the meaning of the word Geoethics, formalizing its definition, and identifying a framework of reference values on which the geoscience community can base more effective codes of conduct. IAPG members have published numerous books and articles in peer reviewed international journals, and organized scientific sessions to bring geoethics at the most important geoscience conferences. Geoethical issues have been included in the European project ENVRI-Plus, dedicated to the environmental and solid Earth research infrastructures. Moreover, the most prestigious geoscience organizations around the world now recognize geoethics as an important issue that warrants attention. This success was confirmed by the high quality of contents and the large participation of scientists in the 6 technical sessions and single panel session on geoethics organized by IAPG at the 35th IGC - International Geological Congress, held in 2016 in Cape Town (South Africa), with the cooperative work of different geoscience organizations (IUGS-TGGP - Task Group on Global Geoscience Professionalism; GSL - Geological Society of London; EFG - European Federation of Geologists; EGS - EuroGeoSurveys; AGI - American Geosciences Institute; AGU - American Geophysical Union, and AAWG - African Association of Women in Geosciences).

    Dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. This major public health problem has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. Essential oil (EO) constituents can affect insect's behaviour, being potentially effective in pest control. The present study evaluated the potential use of Foenicultm vulgare (fennel) EO in the control of the dengue vector Aedes aegypti. EOs isolated from fennel aerial parts collected in Cape Verde and from a commercial fennel EO of Portugal were analysed by NMR, GC and GC-MS. trans-Anethole (32 and 30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in both cases) were the main compounds identified in the EOs isolated from fennel from Cape Verde and Portugal, respectively. The larvicidal activity of the EOs and its major constituents were evaluated, using WHO procedures, against third instar larvae ofAe. aegypti for 24 h. Pure compounds, such as limonene isomers, were also assayed. The lethal concentrations LC50, C90 and LC99 were determined by probit analysis using mortality rates of bioassays. A 99% mortality of Ae. aegypti larvae was estimated at 37.1 and 52.4 µL L-1 of fennel EOs from Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs from both countries displayed strong larvicidal effect against Ae. aegypti, the Cape Verde EO being as active as one of its major constituents, (-)-limonene.

  14. Causes of plant diversification in the Cape biodiversity hotspot of South Africa.

    The Cape region of South Africa is one of the most remarkable hotspots of biodiversity with a flora comprising more than 9000 plant species, almost 70% of which are endemic, within an area of only ± 90,000 km2. Much of the diversity is due to an exceptionally large contribution of just a few clades that radiated substantially within this region, but little is known about the causes of these radiations. Here, we present a comprehensive analysis of plant diversification, using near complete species-level phylogenies of four major Cape clades (more than 470 species): the genus Protea, a tribe of legumes (Podalyrieae) and two speciose genera within the iris family (Babiana and Moraea), representing three of the seven largest plant families in this biodiversity hotspot. Combining these molecular phylogenetic data with ecological and biogeographical information, we tested key hypotheses that have been proposed to explain the radiation of the Cape flora. Our results show that the radiations started throughout the Oligocene and Miocene and that net diversification rates have remained constant through time at globally moderate rates. Furthermore, using sister-species comparisons to assess the impact of different factors on speciation, we identified soil type shifts as the most important cause of speciation in Babiana, Moraea, and Protea, whereas shifts in fire-survival strategy is the most important factor for Podalyrieae. Contrary to previous findings in other groups, such as orchids, pollination syndromes show a high degree of phylogenetic conservatism, including groups with a large number of specialized pollination syndromes like Moraea. We conclude that the combination of complex environmental conditions together with relative climatic stability promoted high speciation and/or low extinction rates as the most likely scenario leading to present-day patterns of hyperdiversity in the Cape.

    1997-01-01

    Five years ago, in August 1992, a tropical depression off the western coast of Africa formed, intensifying and gathering storm clouds as it began its journey westward. By the time it reached the US mainland, it had become a full-fledged hurricane -- Hurricane Andrew -- that blasted over south Florida and into south-central Louisiana. In Florida City, Fla., things went from bad to worse. One piece of metal debris -- airborne from the hurricane's 145 mile-per-hour winds -- punctured an oil tank, triggering a rapidly spreading oil spill that needed to be contained, and fast. The tank had a mechanism whereby oil was replenished when the container was less than full; so as oil was sucked out by the high winds, more came pouring in. In addition, a berm that would have somewhat contained the spill was stuck in open position. Enter Cape Canaveral Marine Services, Inc., (CCMS, Cape Canaveral, Fla.), an environmental services company well-versed in emergency spill response activities. Within seven weeks, CCMS had cleaned up and mitigated the impacts of the spill. Although the job posed significant challenges, the company was uniquely situated to respond quickly, efficiently, and effectively. After all, it had already been in the business for 20 years

    Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

  18. Lessons from the past: Historical perspectives of mental health in the Eastern Cape

    2014-07-01

    Full Text Available The development of mental health services in the Eastern Cape Province is inextricably entwined in South Africa’s colonial history and the racist policy of apartheid. Prior to the development of mental hospitals, mental health services were provided through a network of public and mission hospitals. This paper explores the development of early hospital and mental health services in the Eastern Cape from the time of the Cape Colony to the dissolution of apartheid in 1994, and highlights the influence of colonialism, race and legislation in the development of mental health services in this province. The objective is to provide a background of mental health services in order to identify the historical factors that have had an impact on the current shortcomings in the provision of public sector mental health services in the province. This information will assist in the future planning and development of a new service for the province without the stigma of the past. This research indicates that one lesson from the past should be the equitable distribution of resources for the provision of care for all that inhabit this province, as enshrined in South Africa’s constitution.

  4. FOGO-2014: Monitoring the Fogo 2014 Eruption, Cape Verde

    Science.gov (United States)

    Fernandes, Rui; Faria, Bruno

    2015-04-01

    Fogo volcano, located in the Cape Verde Archipelago offshore Western Africa, is a complete stratovolcano system that was created by the Cape Verde hotspot, forming the island of Fogo. The top (Pico do Fogo) reaches ~2830m above sea level, and raises ~1100m above Chã das Caldeiras, an almost flat circular area with approximately 10 kilometres in the north-south direction and 7 kilometres in the east-west direction. Chã das Caldeiras, surrounded towards the West by the ~1000m high Bordeira rampart, has been inhabited since the early 20th Century, because it is one of the most productive agricultural areas in this semi-arid country. Fogo volcano erupted on November 23, 2014 (~10:00UTC) on a subsidiary vent of the main cone, after 19 years of inactivity. C4G (Collaboratory for Geosciences), a distributed research infrastructure created in 2014 in the framework of the Portuguese Roadmap for Strategic Research Infrastructures, immediately offered support to the Cape Verdean authorities, with the goal of complementing the permanent geophysical monitoring network operated in Fogo island by INMG, the Cape Verdean Meteorological and Geophysical Institute. This permanent network is composed of seven seismographic stations and three tiltmeter stations, and the data is transmitted in real time to the INMG geophysical laboratory in São Vicente Island, where it is analysed on a routine basis. Pre-eruptive activity started to be detected by the permanent monitoring network on October 2014, with earthquakes occurring at depths larger than 15 km. These events led to a first volcanic warning to the Cape Verdean Civil Protection Agency. On November 22 several volcano-tectonic earthquakes were recorded at shallow depths, indicating shallow fracturing. On the basis of this activity, INMG issued a formal alert of an impending eruption to the Civil Protection Agency, ~24 hours before the onset of the eruption. Volcanic tremor and clear tiltmeter signals were recorded about one hour

  5. Long term fine aerosols at the Cape Grim global baseline station: 1998 to 2016

    When air masses were arriving from the baseline sector, the maximum concentration of aged sea salt was 1.3 μg/m3, compared to overall maximum of 4.9 μg/m3. For secondary sulfates and nitrates the maximum concentrations were 2.5 and 7.5 μg/m3 from the baseline sector and overall, respectively. While measurements at Cape Grim can be affected from long range transport from mainland Australia and some local Tasmanian sources, the average concentrations of anthropogenic sources are still considerably lower than those measured at more populated areas. For example, at Lucas Heights (located south-west of the Sydney central business district, with little local sources) the average concentrations of secondary sulfates/nitrates and aged sea air were 1.4 and 1.0 μg/m3, respectively; compared to average concentrations of 0.8 and 0.6 μg/m3, at Cape Grim. The average concentrations of smoke were compatible at the two sites. The impact of primary aerosols from vehicle exhaust at Cape Grim was limited and no corresponding fingerprint was resolved.

  6. Improving Access to Pediatric Cardiology in Cape Verde via a Collaborative International Telemedicine Service.

    2015-01-01

    This paper addresses the role of international telemedicine services in supporting the evacuation procedures from Cape Verde to Portugal, enabling better quality and cost reductions in the management of the global health system. The Cape Verde, as other African countries, health system lacks many medical specialists, like pediatric cardiologists, neurosurgery, etc. In this study, tele-cardiology shows good results as diagnostic support to the evacuation decision. Telemedicine services show benefits while monitoring patients in post-evacuation, helping to address the lack of responsive care in some specialties whose actual use will help save resources both in provision and in management of the evacuation procedures. Additionally, with tele-cardiology collaborative service many evacuations can be avoided whereas many cases will be treated and followed locally in Cape Verde with remote technical support from Portugal. This international telemedicine service enabled more efficient evacuations, by reducing expenses in travel and housing, and therefore contributed to the health system's improvement. This study provides some evidence of how important telemedicine really is to cope with both the geography and the shortage of physicians.

    Full Text Available Adsorption and desorption isotherms of fresh and dried Cape gooseberry (Physalis peruviana L. were determined at three temperatures (20, 40 and 60 °C using a gravimetric technique. The data obtained were fitted to several models including Guggenheim-Anderson- De Boer (GAB, Brunauer-Emmett-Teller (BET, Henderson, Caurie, Smith, Oswin, Halsey and Iglesias-Chirife. A non-linear least square regression analysis was used to evaluate the models. The Iglesias-Chirife model fitted best the experimental data. Isosteric heat of sorption was also determined from the equilibrium sorption data using the Clausius-Clapeyron equation and was found to decrease exponentially with increasing moisture content. The enthalpy-entropy compensation theory was applied to the sorption isotherms and indicated an enthalpy-controlled sorption process. Glass transition temperature (Tg of Cape gooseberry was also determined by differential scanning calorimetry and modelled as a function of moisture content with the Gordon-Taylor, the Roos and the Khalloufi models, which proved to be excellent tools for predicting glass transition of Cape gooseberry.

  14. Desertification of subtropical thicket in the Eastern Cape, South Africa: Are there alternatives?

    Science.gov (United States)

    Kerley, G I; Knight, M H; de Kock, M

    1995-01-01

    The Eastern Cape Subtropical Thicket (ECST) froms the transition between forest, semiarid karroid shrublands, and grassland in the Eastern Cape, South Africa. Undegraded ECST forms an impenetrable, spiny thicket up to 3 m high consisting of a wealth of growth forms, including evergreen plants, succulent and deciduous shrubs, lianas, grasses, and geophytes. The thicket dynamics are not well understood, but elephants may have been important browsers and patch disturbance agents. These semiarid thickets have been subjected to intensive grazing by domestic ungulates, which have largely replaced indigenous herbivores over the last 2 centuries. Overgrazing has extensively degraded vegetation, resulting in the loss of phytomass and plant species and the replacement of perennials by annuals. Coupled with these changes are alterations of soil structure and secondary productivity. This rangeland degradation has largely been attributed to pastoralism with domestic herbivores. The impact of indigenous herbivores differs in scale, intensity, and nature from that of domestic ungulates. Further degradation of the ECST may be limited by alternative management strategies, including the use of wildlife for meat production and ecotourism. Producing meat from wildlife earns less income than from domestic herbivores but is ecologically sustainable. The financial benefits of game use can be improved by developing expertise, technology, and marketing. Ecotourism is not well developed in the Eastern Cape although the Addo Elephant National Park is a financial success and provides considerable employment benefits within an ecologically sustainable system. The density of black rhinoceros and elephant in these thickets is among the highest in Africa, with high population growth and the lowest poaching risk. The financial and ecological viability of ecotourism and the conservation status of these two species warrant expanding ecotourism in the Eastern Cape, thereby reducing the probability of

    The Health Workers Society (HWS), founded in 1980, was one of several progressive health organisations that fought for a democratic health system in South Africa. We document the sociopolitical context within which it operated and some of its achievements. HWS, many of whose members were staff and students of the University of Cape Town (UCT), provided a forum for debate on health-related issues, politics and society, and worked closely with other organisations to oppose the apartheid state's health policies and practices. They assisted with the formation of the first dedicated trade union for all healthcare workers and were one of the first to pioneer the primary healthcare approach in an informal settlement in Cape Town.

  8. Irony and joking in ethnographic fieldwork: Reflections from Santo Antão Island (Cape Verde

    Directory of Open Access Journals (Sweden)

    Martina Giuffrè

    2016-08-01

    Full Text Available In this essay I address the crucial role of irony and joking in anthropology with a focus on the ethnographic relationship. My starting point is field research carried out from 2001 to 2004 on Santo Antão island (Cape Verde, specifically Ponta do Sol. In Cape Verdean practice, jokes and irony represent customary communicational modes and important tools for building relationships: the ultimate means of achieving “cultural intimacy”, they are used almost as rites of initiation to bring newcomers into the community and at the same time to manage ambiguities. Indeed, it was precisely through irony that my interlocutors were able to perfectly capture my ambiguous insider/outsider position. In this specific ethnographic context, the ironic relationship is understood as both a key communication tool in the ethnographic encounter and an unusual rite of passage: although strangers/anthropologists can only be accepted if they become Cape Verdean to some degree, in reality they are never really able to complete this passage. The essay briefly reviews irony and joking in anthropology and focuses on aspects of ironic interactions in Cape Verde that are linked to intercultural relations in the ethnographic context as a site of uncertain communication. I stress how, especially in intercultural contexts, the ambiguity of irony represents not a barrier to communication but rather a key element of understanding between anthropologists and informants as well as a significant heuristic device.

  9. GROWING UP IN PORTUGAL: CAPE VERDEAN ANCESTRY CHILDREN EXHIBIT LOW OVERWEIGHT AND OBESITY COMPARED WITH PORTUGUESE IN URBAN LISBON.

    André, A L; Padez, C; Rosado-Marques, V; Griffiths, P L; Varela-Silva, M I

    2017-11-01

    Portugal has one of the highest rates of childhood overweight and obesity in Europe. However, little is known about the health of ethnic minorities living in its capital city, Lisbon. The Cape Verdean community in Lisbon tend to have low educational levels, material deprivation and struggle with discrimination and racism, factors that would probably be associated with a higher prevalence of overweight and obesity. Data for the Cape Verdean population were collected in three different time periods by three different research teams in 1993, 2009 and 2013 and included children aged 6-12 years living in the Cova da Moura neighbourhood of the Greater Lisbon Metro Area. The Portuguese national survey was conducted between 2009 and 2010 at public and private schools in mainland Portugal and included height, weight, skinfolds and arm and waist circumferences. From these survey data body mass index (BMI) and prevalence of stunting (chronic malnutrition - low height-for-age) and underweight (low weight-for-age) were calculated according to reference values proposed by Frisancho (2008). Overweight and obesity prevalence values were defined based on the references established by the International Obesity Task Force. The results show significant differences in height between Cape Verdean and Portuguese boys and girls. Generally, Cape Verdeans' growth falls within the healthy range of international growth references across all of the survey data collected. Cape Verdean rates for combined overnutrition (overweight and obesity) in 2013 (9.8% for boys and 16.7% for girls) were lower than those of the Portuguese (33% for boys and 31.7% for girls). Logistic regression models showed that Cape Verdean children had a lower risk of being overweight or obese when accounting for breast-feeding, birth weight, maternal education and occupation. Despite living in a deprived neighbourhood these Cape Verdean children seemed to have grown more healthily than Portuguese ancestry children. The

    Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

  17. Patterns of genetic diversity in three plant lineages endemic to the Cape Verde Islands.

    Conservation of plant diversity on islands relies on a good knowledge of the taxonomy, distribution and genetic diversity of species. In recent decades, a combination of morphology- and DNA-based approaches has become the standard for investigating island plant lineages and this has led, in some cases, to the discovery of previously overlooked diversity, including 'cryptic species'. The flora of the Cape Verde archipelago in the North Atlantic is currently thought to comprise ∼740 vascular plant species, 92 of them endemics. Despite the fact that it is considered relatively well known, there has been a 12 % increase in the number of endemics in the last two decades. Relatively few of the Cape Verde plant lineages have been included in genetic studies so far and little is known about the patterns of diversification in the archipelago. Here we present an updated list for the endemic Cape Verde flora and analyse diversity patterns for three endemic plant lineages (Cynanchum, Globularia and Umbilicus) based on one nuclear (ITS) and four plastid DNA regions. In all three lineages, we find genetic variation. In Cynanchum, we find two distinct haplotypes with no clear geographical pattern, possibly reflecting different ploidy levels. In Globularia and Umbilicus, differentiation is evident between populations from northern and southern islands. Isolation and drift resulting from the small and fragmented distributions, coupled with the significant distances separating the northern and southern islands, could explain this pattern. Overall, our study suggests that the diversity in the endemic vascular flora of Cape Verde is higher than previously thought and further work is necessary to characterize the flora.

    2013-01-01

    A Solanum species long considered an American introduction to the Cape Verde Islands off the west coast of Africa is identified as Solanum rigidum, a member of the Eggplant clade of Old World spiny solanums (Solanum subgenus Leptostemonum) and is probably endemic to the Cape Verde Islands. Collections of this species from the Caribbean are likely to have been introduced from the Cape Verde Islands on slave ships. We discuss the complex nomenclatural history of this plant and provide a detailed description, illustration and distribution map. The preliminary conservation status of Solanum rigidum is Least Concern, but needs to be reassessed in light of its endemic rather than introduced status.

    2002-01-01

    Granulite to transitional granulite facies gneisses exposed at Cape Bruce, Rayner Complex, East Antarctica, record three main orogenic/magmatic phases: (1) intrusion of c. 1000-980 Ma felsic orthogneisses into Mid-Proterozoic metasediments, contemporary with the development of north-trending reclined to recumbent folds; (2) extensive c. 980-900 Ma felsic magmatism, including equivalents of the Mawson Charnockite, which accompanied the development of upright, east-northeast-trending folds; and (3) ultramylonite zones of uncertain age. The first two phases are known as the Rayner Structrual Episode, the effects of which are similar in rocks to the east of Cape Bruce, at Mawson, and in the northern Prince Charles Mountains. Archaean rocks immediately to the west of Cape Bruce were tectonically reworked during the Rayner Structural Episode. The first orogenic phase is inferred to represent the collision between a wedge-shaped Proterozoic block comprising rocks of the Mawson Coast and Eastern Ghats Province, with the Archaean Napier Complex. The second orogenic phase included a major period of crustal growth through emplacement of the Mawson Charnockite and equivalents. (author). 41 refs., 6 figs., 1 tab

    2018-03-28

    Hereditary angio-oedema (HAE) is an autosomal dominant condition caused by a deficiency in the C1-esterase inhibitor protein, resulting in increased bradykinin release. It presents clinically with recurrent attacks of angio-oedema, commonly affecting the limbs, face, upper airway and gastrointestinal tract. Little is known about this condition in sub-Saharan Africa. To analyse and report on the clinical presentation and treatment of patients with HAE in the Western Cape Province, South Africa. A retrospective analysis was conducted on a series of 60 cases of HAE seen between 2010 and 2015 at the Allergy Diagnostic and Clinical Research Unit, University of Cape Town Lung Institute, and the Allergy Clinic at Groote Schuur Hospital, Cape Town. The findings in 43 cases of type 1 HAE are described. Parameters assessed included age, gender, age of diagnosis, duration of illness, family history, identifiable triggers, average duration of attack, number of attacks per year and type of attack. A total of 43 patients were included in this study. Of these, 65.1% (28/43) were female. The median age at diagnosis was 20 years (interquartile range (IQR) 10 - 27) and the median duration of illness 10.5 years (IQR 6 - 22). Of the patients, 62.8% (27/43), 32.6% (14/43) and 4.7% (2/43) were of mixed ancestry, white and black African, respectively; 51.2% (22/43) were index cases, with the remaining 48.8% (21/43) diagnoses via family member screening, 12 families making up the majority of the cohort. The mean (standard deviation) duration of an acute attack was 49 (25.8) hours, and 64.3% (27/42), 71.4% (30/42), 14.3% (6/42) and 88.1% (37/42) of patients experienced facial or upper airway, abdominal, external genitalia and limb attacks, respectively. Danazol for long-term prophylaxis was used in 21 patients, while C1-inhibitor concentrate (Berinert) was accessed for short-term prophylaxis in only four patients. Acute life-threating attacks were treated with fresh frozen plasma in 11

  7. Gangsterism on the Cape Flats: A challenge to ‘engage the powers’

    Directory of Open Access Journals (Sweden)

    Nadine F. Bowers Du Toit

    2014-11-01

    Full Text Available One of the most pressing issues in the urban ghettos of the Cape Flats is that of gangsterism and the discourse of power and powerlessness that is its lifeblood. Media coverage over the past two years was littered with news on gangsterism as the City of Cape Town struggles to contain what some labelled a pandemic. It is a pandemic that is closely tied to a deprivation trap of poverty, marginalisation, isolation, unemployment and, ultimately, powerlessness. The latter concept of powerlessness and its interplay with these factors constituted the main thrust of this article as it explores the concept of power (and powerlessness as deeply relational with the economic, psycho-social and spiritual dimensions. It is proposed that Kingdom power challenges the status quo within such contexts and offers the church an alternative framework within which to engage prophetically.

  11. The North Cape oil spill assessment: PAHs in oil

    International Nuclear Information System (INIS)

    Brown, J.; Boehm, P. D.; Hardestine, J. H.; Douglas, G. S.

    1997-01-01

    The North Cape oil spill in January 1996 resulted in the release of an estimated 827,000 gallons of No. 2 home heating oil into the nearshore turbulent waters of coastal Rhode Island. The oil was mixed into the water column and was transported on the surface as well as below the surface. Some of the spilled oil entered the coastal ponds behind the beaches. Sampling and chemical analysis for detailed suites of petroleum saturated and polycyclic aromatic hydrocarbons (PAHs) was undertaken as part of the assessment of the fate of the oil spill and of the exposure to the marine environment. The ponds were found to contain significant quantities of background petroleum hydrocarbons, including petrogenic PAHs and combustion PAHs. Initial assessment pointed (incorrectly as it turned out) to widespread contamination due only to the North Cape spill. Application of advanced chemical fingerprinting approaches, and geochemical biomarker data illustrated that many of the PAHs consisted of combustion-related 4- and 5-ringed PAHs, attributable to diesel fuel used routinely by boats in the area. The analysis demonstrated that the use of non-specific total PAH data and insufficient fingerprinting and allocation of petrogenic residues has the potential to overestimate contamination and hence injury to the environment in similar oil spill situations

    2013-01-01

    At the end of 2009, 21,313 cases of dengue-3 virus (DENV-3) were reported in the islands of Cape Verde, an archipelago located in the Atlantic Ocean 570 km from the coast of western Africa. It was the first dengue outbreak ever reported in Cape Verde. Mosquitoes collected in July 2010 in the city of Praia, on the island of Santiago, were identified morphologically as Aedes aegypti formosus. Using experimental oral infections, we found that this vector showed a moderate ability to transmit the epidemic dengue-3 virus, but was highly susceptible to chikungunya and yellow fever viruses.

    Full Text Available The complex problem of drug abuse and drug-related crimes in communities in the Western Cape province cannot be studied in isolation but through the system they are embedded in. In this paper, a theoretical model to evaluate the syndemic of substance abuse and drug-related crimes within the Western Cape province of South Africa is constructed and explored. The dynamics of drug abuse and drug-related crimes within the Western Cape are simulated using STELLA software. The simulation results are consistent with the data from SACENDU and CrimeStats SA, highlighting the usefulness of such a model in designing and planning interventions to combat substance abuse and its related problems.

  14. Gaseous elemental mercury depletion events observed at Cape Point during 2007–2008

    Directory of Open Access Journals (Sweden)

    E.-G. Brunke

    2010-02-01

    Full Text Available Gaseous mercury in the marine boundary layer has been measured with a 15 min temporal resolution at the Global Atmosphere Watch station Cape Point since March 2007. The most prominent features of the data until July 2008 are the frequent occurrences of pollution (PEs and depletion events (DEs. Both types of events originate mostly within a short transport distance (up to about 100 km, which are embedded in air masses ranging from marine background to continental. The Hg/CO emission ratios observed during the PEs are within the range reported for biomass burning and industrial/urban emissions. The depletion of gaseous mercury during the DEs is in many cases almost complete and suggests an atmospheric residence time of elemental mercury as short as a few dozens of hours, which is in contrast to the commonly used estimate of approximately 1 year. The DEs observed at Cape Point are not accompanied by simultaneous depletion of ozone which distinguishes them from the halogen driven atmospheric mercury depletion events (AMDEs observed in Polar Regions. Nonetheless, DEs similar to those observed at Cape Point have also been observed at other places in the marine boundary layer. Additional measurements of mercury speciation and of possible mercury oxidants are hence called for to reveal the chemical mechanism of the newly observed DEs and to assess its importance on larger scales.

  19. Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an assessment of Macaronesian and Cape Verde biogeographic marine ecoregions.

    2018-04-23

    The complete list of Canarian marine decapods (last update by González Quiles 2003, popular book) currently comprises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde archipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gathering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; divergent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos. To understand/predict south-north faunal movements in a scenario of regional tropicalization, special attention is paid to species having at the Canaries their southernmost occurrence, and also to tropical African warm-affinity species.

    2017-01-01

    Background: With modern information technology, an overwhelming amount of data is available on different aspects of societies. Our research investigated the feasibility of using secondary data sources to get an overview of determinants of health and health outcomes in different population strata of Cape Town, a large city of South Africa. Methods: The methodological approach of secondary-data analysis was similar in the different disciplines: Biological Anthropology, Public Health, Environmental Health, Mental Health, Palliative Care, Medical Psychology and Sociology at the University of Freiburg and Public Health at the University of Cape Town. The teams collected information on Cape Town through Internet searches and published articles. The information was extracted, analyzed, condensed, and jointly interpreted. Results: Data show the typical picture of a population in epidemiological and demographic transition exposed to often difficult social, mental, and physical environmental conditions. Comparison between low and higher socioeconomic districts demonstrated that the former had higher air pollution, poorer water quality, and deficient sanitary conditions in addition to sub-optimal mental health services and palliative care. Conclusion: Although important information gaps were identified, the data draw attention to critical public health interventions required in poor health districts, and to motivate for pro-equity policies.

    The vast and complex coast of the Magellan Region of extreme southern Chile possesses a diversity of habitats including fjords, deep channels, and extensive kelp forests, with a unique mix of temperate and sub-Antarctic species. The Cape Horn and Diego Ramírez archipelagos are the most southerly locations in the Americas, with the southernmost kelp forests, and some of the least explored places on earth. The giant kelp Macrocystis pyrifera plays a key role in structuring the ecological communities of the entire region, with the large brown seaweed Lessonia spp. forming dense understories. Kelp densities were highest around Cape Horn, followed by Diego Ramírez, and lowest within the fjord region of Francisco Coloane Marine Park (mean canopy densities of 2.51 kg m-2, 2.29 kg m-2, and 2.14 kg m-2, respectively). There were clear differences in marine communities among these sub-regions, with the lowest diversity in the fjords. We observed 18 species of nearshore fishes, with average species richness nearly 50% higher at Diego Ramírez compared with Cape Horn and Francisco Coloane. The number of individual fishes was nearly 10 times higher at Diego Ramírez and 4 times higher at Cape Horn compared with the fjords. Dropcam surveys of mesophotic depths (53–105 m) identified 30 taxa from 25 families, 15 classes, and 7 phyla. While much of these deeper habitats consisted of soft sediment and cobble, in rocky habitats, echinoderms, mollusks, bryozoans, and sponges were common. The southern hagfish (Myxine australis) was the most frequently encountered of the deep-sea fishes (50% of deployments), and while the Fueguian sprat (Sprattus fuegensis) was the most abundant fish species, its distribution was patchy. The Cape Horn and Diego Ramírez archipelagos represent some of the last intact sub-Antarctic ecosystems remaining and a recently declared large protected area will help ensure the health of this unique region.

    Cape gooseberry (Physalis peruviana L.) fruits are highly perishable berries that exhibit a climacteric respiratory behavior. The objective of this study was to evaluate the effect of ethylene and the ethylene action inhibitor 1-methylcyclopropene on the postharvest behavior of cape gooseberry fruits (ecotype Colombia). Fruits were treated with ethylene, in an ethephon application (1000 µL L -1 ), and pretreated with 1-methylcyclopropene (1 µL L -1 ), 1-methylcyclopropene+ethylene, and results compared with a control without application. Subsequently, the fruits were maintained at room temperature (20 ℃, 75% RH) for up to 11 days. The pretreatment of the cape gooseberry fruits with 1-methylcyclopropene delayed most of the ripening-associated parameters, with a reduction in the respiration rate and ethylene production, skin color development, total soluble solids, total carotenoid content, loss of firmness, loss of total titratable acidity and emission of volatile compounds such as ethyl octanoate, ethyl butanoate, ethyl decanoate, and hexyl decanoate. Conversely, application of ethephon accelerated most of these physiological changes and also overcame most of the effects prevented by the ethylene action inhibitor. Altogether, the results supported the idea of a climacteric-like behavior for cape gooseberry fruits and pointing out that the pretreatment with 1-methylcyclopropene may be a promising and efficient postharvest treatment to delay maturity and extend the postharvest period. © The Author(s) 2016.

    Despite the use of maintenance medication, recurrence rates in bipolar affective disorder (BPAD) are high. To date, there are no clinical trials that have investigated the use of psychological interventions in bipolar disorder in Pakistan. The purpose of the study was to assess the feasibility and acceptability of a culturally adapted bipolar psychoeducation programme (CaPE) in Pakistan. Thirty-four euthymic bipolar I and II outpatients were randomized to either 12 weekly sessions of individual psychoeducation plus Treatment As Usual (Intervention) or Treatment As Usual (TAU) (Control). Outcomes were assessed using the Young Mania Rating Scale (YMRS), Beck Depression Inventory (BDI), EuroQoL (EQ-5D), Bipolar Knowledge and Attitudes and Questionnaire (BKAQ), and a self-reported measure of medication adherence (Morisky Medication Adherence Scale-4 items, MMAS-4). Effect sizes were derived from baseline adjusted standardized regression coefficients. Retention in the study was good, 80% of patients in the TAU follow-up assessment and 100% of patients in the CaPE group attended all 12 sessions. Patient satisfaction was higher in the CaPE group relative to control (ES = 1.41). Further, there were large effect sizes shown for CaPE versus TAU for medication adherence (MMAS-4: ES = 0.81), knowledge and attitudes towards bipolar (BKAQ: ES = 0.68), mania (YMRS: ES = 1.18), depression (BDI: ES = 1.17) and quality of life measures (EQ-5D: ES ⇒ 0.88). Culturally adapted psychoeducation intervention is acceptable and feasible, and can be effective in improving mood symptoms and knowledge and attitudes to BPAD when compared with TAU. Larger scale studies are needed to confirm our findings. Clinicaltrials.gov identifier NCT02210390.

    2013-02-18

    In Maio Island, Republic of Cape Verde, a seven-year old mongrel female dog exhibiting severe generalized adenomegaly and a poor body condition was examined during an animal welfare campaign. A blood smear was drawn from peripheral blood collection and several organisms consistent with Dirofilaria immitis microfilariae were identified. Both the antigen test conducted from plasma and the RT-PCR test performed from the blood smear sample were positive for D. immitis. This is, to the best of our knowledge, the first report of D. immitis in Cape Verde. The fact that the dog was autochthonous and had never left the island strongly suggests there might be other animals infected with the parasite. Our finding confirms the existence of the parasite in the canine population and necessarily implies the presence of a competent vector. As a serious cardiopulmonary disease and with the risk of the pathogen spreading rapidly, broader epidemiological studies need to be conducted to determine D. immitis prevalence in the canine population of Maio Island.

    The GeoCAPE Filter Radiometer (FR) Study is a different instrument type than all of the previous IDL GeoCape studies. The customer primary goals are to keep mass, volume and cost to a minimum while meeting the science objectives and maximizing flight opportunities by fitting on the largest number of GEO accommodations possible. Minimize total mission costs by riding on a commercial GEO satellite. For this instrument type, the coverage rate, km 2 min, was significantly increased while reducing the nadir ground sample size to 250m. This was accomplished by analyzing a large 2d area for each integration period. The field of view will be imaged on a 4k x 4k detector array of 15 micrometer pixels. Each ground pixel is spread over 2 x 2 detector pixels so the instantaneous field of view (IFOV) is 2048 X 2048 ground pixels. The baseline is, for each field of view 50 sequential snapshot images are taken, each with a different filter, before indexing the scan mirror to the next IFOV. A delta would be to add additional filters.

    1986-01-01

    In May the southern hemisphere circumpolar jet stream accelerates in response to a growing temperature gradient between the pole and equator. Initially, the jet stream may 'spin up' in pulses, causing the upper air current to become unstable and to meander equatorwards out of the higher latitudes (40-50 degrees S). Winter storms induced by the jet stream and which move, from west to east, to the south of the African continent are then guided by the upper air currents further north. Between 15 and 17 May 1984, such a sequence of synoptic weather events developed and the south-western Cape came under the influence of the 'roaring 40's'. In this article a chronology of the storm and its meteorological effects are described using data collected at the Koeberg nuclear power station, the Cape Town Airport Weather Office and across the south-western Cape. The destructive effects of the storm, particularly felt along the coast as a result of large swells and a significant storm surge, are discussed

    The Australia Global Baseline monitoring station at Cape Grim in north western Tasmania is operated by the Australian Bureau of Meteorology. ANSTO has been sampling, measuring and characterising fine particles of 2.5 μm diameters and less (PM2.5) at Cape Grim since the middle of 1992. Accelerator based ion beam analysis (IBA) techniques [2-41 have been used to identify over 25 different elemental species present in over 500 filters collected to date. The elements measured by PIXE, PIGME, ERDA and RBS include, H, C, N, O, F, Na, Al, Si, P, S, Cl, K, Ca, Ti, V, Mn, Fe, Co, Ni, Cu, Zn, Br and Pb. Of the measured elements not listed the majority occurred at concentrations below 10 ng/m 3 . The average monthly mass variations over the 5 year period from 1992 to 1997 are given. The average non-soil potassium was 92% of the total potassium, showing that the vast majority of fine potassium was associated with smoke from biomass burning. The highest lead value of 542 ng/m 3 occurred on 21 June 1992 and was associated with 337 ng/m 3 of bromine which, after correction for bromine in sea salt (Na was 3 ), was about the correct ratio to be associated with combustion of leaded petrol in motor vehicles

    Rapanea melanophloeos(Cape beech)is a fruit-bearing tree indigenous to Southern Africa which produces edible fruit. Seed samples obtained from ripe fruit of the Cape beech trees had their proximate analysis and lipid profiling done. The dry matter and ash contributed 91.29 +- 0.00 %, 1.50 +- 0.01 % of the mass of the seed. Whilst the other proximate analytes namely crude fibre, crude protein and ether extract made up 5.71 +- 0.43 %, 10.50 +- 0.49 % and 4.75 +- 0.09 percentage of the mass of the seeds respectively. The fatty acid profile of the seed oil revealed Linoleic acid (50.43 +- 0.38 %) to be the most dominant. R. melanophloeos seeds are not a viable source of nutrients. (author)

    During the 1830s there arose a strong international movement, promoted by Carl Friedrich Gauss and Alexander von Humboldt, to characterise the earth's magnetic field. By 1839 the Royal Society in London, driven by Edward Sabine, had organised a "Magnetic Crusade" - the establishment of a series of magnetic and meteorological observatories around the British Empire, including New Zealand, Australia, St Helena and the Cape. This article outlines the history of the latter installation, its buildings and what became of them.

  8. Cardioprotection of CAPE-oNO2 against myocardial ischemia/reperfusion induced ROS generation via regulating the SIRT1/eNOS/NF-κB pathway in vivo and in vitro

    Full Text Available Caffeic acid phenethyl ester (CAPE could ameliorate myocardial ischemia/reperfusion injury (MIRI by various mechanisms, but there hadn’t been any reports on that CAPE could regulate silent information regulator 1 (SIRT1 and endothelial nitric oxide synthase (eNOS to exert cardioprotective effect. The present study aimed to investigate the cardioprotective potential of caffeic acid o-nitro phenethyl ester (CAPE-oNO2 on MIRI and the possible mechanism based on the positive control of CAPE. The SD rats were subjected to left coronary artery ischemia /reperfusion (IR and the H9c2 cell cultured in hypoxia/reoxygenation (HR to induce the MIRI model. Prior to the procedure, vehicle, CAPE or CAPE-oNO2 were treated in the absence or presence of a SIRT1 inhibitor nicotinamide (NAM and an eNOS inhibitor Nω-nitro-L-arginine methyl ester (L-NAME. In vivo, CAPE and CAPE-oNO2 conferred a cardioprotective effect as shown by reduced myocardial infarct size, cardiac marker enzymes and structural abnormalities. From immunohistochemical and sirius red staining, above two compounds ameliorated the TNF-α release and collagen deposition of IR rat hearts. They could agitate SIRT1 and eNOS expression, and consequently enhance NO release and suppress NF-κB signaling, to reduce the malondialdehyde content and cell necrosis. In vitro, they could inhibit HR-induced H9c2 cell apoptosis and ROS generation by activating SIRT1/eNOS pathway and inhabiting NF-κB expression. Emphatically, CAPE-oNO2 presented the stronger cardioprotection than CAPE both in vivo and in vitro. However, NAM and L-NAME eliminated the CAPE-oNO2-mediated cardioprotection by restraining SIRT1 and eNOS expression, respectively. It suggested that CAPE-oNO2 ameliorated MIRI by suppressing the oxidative stress, inflammatory response, fibrosis and necrocytosis via the SIRT1/eNOS/NF-κB pathway.

    Full Text Available OBJECTIVE: Methotrexate (MTX-associated neurotoxicity is an important clinical problem in cancer patients, but the mechanisms of MTX-induced neurotoxicity are not yet known exactly. The aims of this study were (1 to investigate the possible role of malondialdehyde (MDA, superoxide dismutase (SOD enzyme, glutathione peroxidase (GSH-Px and catalase (CAT in the pathogenesis of MTX-induced neurotoxicity and (2 to determine whether there is a putative protective effect of caffeic acid phenethyl ester (CAPE on MTX-induced neurotoxicity in the spinal cord, brainstem and sciatic nerve of rats. METHODS: A total of 19 adult Wistar male rats were divided into three experimental groups. Group I, control group; Group II, MTX-treated group; and Group III, MTX + CAPE-treated group. MTX was administered to the MTX and MTX + CAPE groups intraperitoneally (IP with a single dose of 20 mg/kg on the second day of the experiment. CAPE was administered to the MTX + CAPE group IP with a dose of 10 μmol/kg for 7 days. RESULTS: In the sciatic nerve and spinal cord tissue, CAT and GSH-Px activities were increased in the MTX group in comparison with the control group. CAPE treatment with MTX significantly decreased CAT and GSH-Px activities in the neuronal tissues of rats in comparison with the MTX group. In the spinal cord and brainstem tissues, SOD activity in the MTX group was decreased in comparison with the control group, but in the sciatic nerve, there was no significant difference. In the spinal cord and brainstem of rats, SOD activity was increased in the CAPE + MTX group when compared with the MTX group. The level of MDA was higher in the MTX group than in the control group. CAPE administration with MTX injection caused a significant decrease in MDA level when compared with the MTX group. CONCLUSION: These results reveal that MTX increases oxidative stress in the sciatic nerve, spinal cord and brainstem of rats and that CAPE has a preventive effect on the

    The nearshore circulation in the lee of a cape under upwelling conditions was studied using in-situ data from 3 consecutive summers (2006-2008). Focus was given to a period between 20 July and 04 August 2006 to study the diurnal variability of the cross-shelf circulation. This period was chosen because it had a steady upwelling-favourable wind condition modulated by a diurnal cycle much similar to sea breeze. The daily variability of the observed cross-shelf circulation consisted of three distinct periods: a morning period with a 3-layer vertical structure with onshore velocities at mid-depth, a mid-day period where the flow is reversed and has a 2-layer structure with onshore velocities at the surface and offshore flow below, and, lastly, in the evening, a 2-layer period with intensified offshore velocities at the surface and onshore flow at the bottom. The observed cross-shelf circulation showed a peculiar vertical shape and diurnal variability different from several other systems described in literature. We hypothesize that the flow reversal of the cross-shelf circulation results as a response to the rapid change of the wind magnitude and direction at mid-day with the presence of the cape north of the mooring site influencing this response. A numerical modelling experiment exclusively forced by winds simulated successfully most of the circulation at the ADCP site, especially the mid-day reversal and the evening's upwelling-type structure. This supports the hypothesis that the cross-shelf circulation at diurnal timescales is mostly wind-driven. By analysing the 3D circulation in the vicinity of Cape Sines we came to the conclusion that the diurnal variability of the wind and the flow interaction with topography are responsible for the circulation variability at the ADCP site, though only a small region in the south of the cape showed a similar diurnal variability. The fact that the wind diurnally undergoes relaxation and intensification strongly affects the

    2013-01-01

    Mantacaprella macaronensis new genus, new species, is described based on specimens collected from Canary Islands and Cape Verde. Mantacaprella is close to the genera Parambus, Pseudolirius, Propodalirius and Paracaprella, but can be distinguished by the combination of the following characteristics: pereopods 3, 4 and 5 two-articulate; pereopods 6 and 7 six-articulate; mandibular molar present and palp absent; male abdomen with a pair of well-developed appendages. The new species has been found living in Cymodocea nodosa meadows and Caulerpa prolifera beds from 8.8 to 14.6 m depth in Gran Canaria (Canary Islands), and in natural rocky and artificial habitats (shipwrecks) at 25 m in Sal Island (Cape Verde). Even though the new species is one of the dominant amphipods inhabiting meadows of Cymodocea nodosa in Gran Canaria and in Cape Verde, it had not been described so far. This reflects the lack of knowledge on Macaronesian invertebrates, such as amphipods, and the need of further taxonomical studies to better characterise the whole biodiversity of this region and to design adequate programmes of management and conservation.

  3. Behavioural correlates of urbanisation in the Cape ground squirrel Xerus inauris

    2012-11-01

    Urbanisation critically threatens biodiversity because of habitat destruction and novel selection pressures. Some animals can respond to these challenges by modifying their behaviour, particularly anti-predator behaviour, allowing them to persist in heavily transformed urban areas. We investigated whether the anti-predator behaviour of the Cape ground squirrel Xerus inauris differed in three localities that differed in their level of urbanisation. According to the habituation hypothesis, we predicted that ground squirrels in urban areas would: (a) be less vigilant and forage more; (b) trade-off flight/vigilance in favour of foraging; and (c) have shorter flight initiation distances (FID) when approached by a human observer. Observations were made in winter and summer at each locality. As expected, ground squirrels in urbanised areas were less vigilant and had shorter FIDs but did not trade-off between foraging and vigilance. In contrast, a population in a non-urbanised locality showed greater levels of vigilance, FID and traded-off vigilance and foraging. A population in a peri-urban locality showed mixed responses. Our results indicate that Cape ground squirrels reduce their anti-predator behaviour in urban areas and demonstrate a flexible behavioural response to urbanisation.

This is a descriptive study that used the bibliometric approach for the production of indicators of scientific production. Operationally, the methodology was developed in four steps: 1) construction of the theoretical framework; 2) data collection sourced from the abstracts of theses and dissertations available in the Capes Thesis Database which presented the issue of prematurity in the period 1987 to 2009; 3) organization, processing and construction of bibliometric indicators; 4) analysis and interpretation of results. Increase in the scientific literature on prematurity during the period 1987 to 2009; production is represented mostly by dissertations; the institution that received prominence was the Universidade de São Paulo. The studies are directed toward the low birth weight and very low birth weight preterm newborn, encompassing the social, biological and multifactorial causes of prematurity. There is a qualified, diverse and substantial scientific literature on prematurity developed in various graduate programs of higher education institutions in Brazil.

  7. Impacts of drought on grape yields in Western Cape, South Africa

    Science.gov (United States)

    Araujo, Julio A.; Abiodun, Babatunde J.; Crespo, Olivier

    2016-01-01

    Droughts remain a threat to grape yields in South Africa. Previous studies on the impacts of climate on grape yield in the country have focussed on the impact of rainfall and temperature separately; meanwhile, grape yields are affected by drought, which is a combination of rainfall and temperature influences. The present study investigates the impacts of drought on grape yields in the Western Cape (South Africa) at district and farm scales. The study used a new drought index that is based on simple water balance (Standardized Precipitation Evapotranspiration Index; hereafter, SPEI) to identify drought events and used a correlation analysis to identify the relationship between drought and grape yields. A crop simulation model (Agricultural Production Systems sIMulator, APSIM) was applied at the farm scale to investigate the role of irrigation in mitigating the impacts of drought on grape yield. The model gives a realistic simulation of grape yields. The Western Cape has experienced a series of severe droughts in the past few decades. The severe droughts occurred when a decrease in rainfall occurred simultaneously with an increase in temperature. El Niño Southern Oscillation (ENSO) appears to be an important driver of drought severity in the Western Cape, because most of the severe droughts occurred in El Niño years. At the district scale, the correlation between drought index and grape yield is weak ( r≈-0.5), but at the farm scale, it is strong ( r≈-0.9). This suggests that many farmers are able to mitigate the impacts of drought on grape yields through irrigation management. At the farm scale, where the impact of drought on grape yields is high, poor yield years coincide with moderate or severe drought periods. The APSIM simulation, which gives a realistic simulation of grape yields at the farm scale, suggests that grape yields become more sensitive to spring and summer droughts in the absence of irrigation. Results of this study may guide decision-making on

    The Hellenic Institute of Marine Archaeology (H.I.M.A.)1 has been conducting an underwater archaeological research in the west coast of southern Pagasetikos Gulf, since 2000. Every year the underwater research focuses on specific archaeological targets that have been recovered during previous field campaigns. The current publication elaborates on the comprehensive documentation of the underwater archaeological site at Cape Glaros, during the 2015 field season, under the direction of the archaeologist Elias Spondylis. The 2015 research campaign was conducted within the framework of the ITACA- Innovation Technologies and Applications for Coastal Archaeological sites European Project (FP7/2007-2013, GA No 606805), at two archaeological sites, namely the Cape Glaros and Metohi. It was among the most important challenges of the project to successfully produce the detailed and accurate 3D mapping of the Cape Glaros site that covers an extended area. Four large concentrations of pottery finds and numerous anchors of different typology have been recorded, that can be dated from the late Hellenistic to the Byzantine periods. This challenge was tackled through the simultaneous implementation of three recording methods; photogrammetry, geodesy and conventional architectural mapping. The workflow of the documentation process, including data acquisition, processing and graphic visualization, along with the derived results are presented below. 1The Hellenic Institute of Marine Archaeology (H.I.M.A.) is a private, non-profit organization, founded in 1973, which undertakes maritime archaeological research under the supervision or in collaboration with the Greek Ministry of Culture. It has over 100 members, with diverse academic credentials, all of whom work, mainly, on a voluntary basis. 3D recording of underwater archaeological sites has been applied to numerous projects that have been carried out by the multidisciplinary team of H.I.M.A. in locations of utmost archaeological

    Full Text Available Background. Drug abuse is as relevant today as ever. Management of such cases on a primary health care level may be challenging, particularly when laboratory facilities are unavailable. Furthermore, substance abuse and its sequelae place a significant burden on the already overstretched primary health care resources in the country, as well as on other ser- vices and society in general. Objectives. The current study surveyed the trends in demand for laboratory determination of amphetamines, opiates, methaqualone, cannabis, cocaine and ethanol for the period 1991 - 2002, in the Western Cape. The survey was conducted by extracting the relevant data from the records of the Pharmacology/Toxicology Laboratory of the University of Stellenbosch and Tygerberg Academic Hospital. This facility processes the largest number of specimens by a single laboratory in the Western Cape. Results. From the data obtained a seasonal pattern emerged for all substances except ethanol, with a trough appearing in early winter. Demand for ethanol analysis was fairly constant throughout the year, with a peak in the last quarter. Ethanol level was the most frequently requested analysis between 1991 and 1997. This concurs with its status as the main substance of abuse in South Africa and the rest of the world. There was an increased demand for analysis of ampheta- mines, opiates, methaqualone, cannabis and cocaine between 1991 and 2002. Generally dominating, next to ethanol, were requests for cannabis and methaqualone analysis. Interesting to note was the increase in demand for opiate analysis, following the trend observed in certain other regions of the world. Conclusion. The analysis trends observed in this study demon- strate global patterns of drug abuse emerging in the Western Cape. The medical and social effects of drug abuse impose a grave responsibility on policymakers to ensure that adequate funding is available for analytical laboratories. Only in such a way can

  10. Simulations of atmospheric methane for Cape Grim, Tasmania, to constrain southeastern Australian methane emissions

    Full Text Available This study uses two climate models and six scenarios of prescribed methane emissions to compare modelled and observed atmospheric methane between 1994 and 2007, for Cape Grim, Australia (40.7° S, 144.7° E. The model simulations follow the TransCom-CH4 protocol and use the Australian Community Climate and Earth System Simulator (ACCESS and the CSIRO Conformal-Cubic Atmospheric Model (CCAM. Radon is also simulated and used to reduce the impact of transport differences between the models and observations. Comparisons are made for air samples that have traversed the Australian continent. All six emission scenarios give modelled concentrations that are broadly consistent with those observed. There are three notable mismatches, however. Firstly, scenarios that incorporate interannually varying biomass burning emissions produce anomalously high methane concentrations at Cape Grim at times of large fire events in southeastern Australia, most likely due to the fire methane emissions being unrealistically input into the lowest model level. Secondly, scenarios with wetland methane emissions in the austral winter overestimate methane concentrations at Cape Grim during wintertime while scenarios without winter wetland emissions perform better. Finally, all scenarios fail to represent a~methane source in austral spring implied by the observations. It is possible that the timing of wetland emissions in the scenarios is incorrect with recent satellite measurements suggesting an austral spring (September–October–November, rather than winter, maximum for wetland emissions.

    Discussion: Pre-hospital acute pain management in the Western Cape does not appear to conform to best practice as Advanced Life Support providers in the Western Cape use low doses of morphine. Chest pain is an important reason for drug administration in acute pre-hospital pain. Multimodal analgesia is not a feature of care in this pre-hospital service. The development of a Clinical Practice Guideline for and training in pre-hospital pain should be viewed as imperative.

    Full Text Available O acrônimo Capes, no Brasil, é sinônimo de programas de pós-graduação. A Capes é uma Agência Governamental do Ministério da Educação que já existe há 62 anos. A sua missão fundamental é a capacitação do pessoal de nível superior para o ensino, e o seu desempenho é considerado excelente, como executora das políticas de capacitação do governo federal. Recentemente, no entanto, a Capes tem sido alvo de críticas de professores e pesquisadores das universidades públicas brasileiras, que hoje a percebem como uma organização pública que caminhou da informalidade e das boas ideias para uma ação centralizadora, intervencionista, inclusive com políticas e medidas que sempre favorecem as regiões mais desenvolvidas do país. Começa a surgir uma percepção crítica entre os acadêmicos professores que considera que o sucesso quantitativo da Capes favorece a alienação da universidade brasileira, principalmente por meio dos programas de pós-graduação, tanto Mestrado quanto Doutorado. Considerando essa discussão, o presente artigo adota o referencial teórico marxista para explicar como se efetiva o processo de alienação conduzido pela Capes e anuído pelas universidades. O artigo apresenta, indica e discute um caminho para romper com a alienação estabelecida por meio da mobilização dos instrumentos legais proporcionados pela Constituição Federal do Brasil.

  17. Do power lines and protected areas present a catch-22 situation for Cape vultures (Gyps coprotheres)?

    2013-01-01

    Cape vulture Gyps coprotheres populations have declined across their range due to multiple anthropogenic threats. Their susceptibility to fatal collisions with the expanding power line network and the prevalence of carcasses contaminated with illegal poisons and other threats outside protected areas are thought to be the primary drivers of declines in southern Africa. We used GPS-GSM units to track the movements and delineate the home ranges of five adult (mean ±SD minimum convex polygon area = 121,655±90,845 km(2)) and four immature (mean ±SD minimum convex polygon area = 492,300±259,427 km(2)) Cape vultures to investigate the influence of power lines and their use of protected areas. The vultures travelled more than 1,000 km from the capture site and collectively entered five different countries in southern Africa. Their movement patterns and core foraging ranges were closely associated with the spatial distribution of transmission power lines and we present evidence that the construction of power lines has allowed the species to extend its range to areas previously devoid of suitable perches. The distribution of locations of known Cape vulture mortalities caused by interactions with power lines corresponded to the core ranges of the tracked vultures. Although some of the vultures regularly roosted at breeding colonies located inside protected areas the majority of foraging activity took place on unprotected farmland. Their ability to travel vast distances very quickly and the high proportion of time they spend in the vicinity of power lines and outside protected areas make Cape vultures especially vulnerable to negative interactions with the expanding power line network and the full range of threats across the region. Co-ordinated cross-border conservation strategies beyond the protected area network will therefore be necessary to ensure the future survival of threatened vultures in Africa.

    Every year, billions of tons of eroded mineral soils from the Saharan Desert and the Sahel region, the largest dust source in the world, cross Mediterranean towards Europe, western Asia and the tropical North Atlantic Ocean as far as the Caribbean and South America. Many aspects of the direct and indirect effects of dust on climate are not well understood and the bulk and surface chemistry of the mineral dust particles determines interactions with gaseous and other particle species. The quantification of the magnitude of warming or cooling remains open because of the strong variability of the atmospheric dust burden and the lack of representative data for the spatial and temporal distribution of the dust composition. CV-Dust is a project that aims at provide a detailed data on the size distribution and the size-resolved chemical and mineralogical composition of dust emitted from North Africa using a natural laboratory like Cape Verde. This archipelago is located in an area of massive dust transport from land to ocean, and is thus ideal to set up sampling devices that are able to characterize and quantify dust transported from Africa. Moreover, Cape Verde's future economic prospects depend heavily on the encouragement of tourism, therefore it is essential to elucidate the role of Saharan dust may play in the degradation of Cape Verde air quality. The main objectives of CV-Dust project are: 1) to characterize the chemical and mineralogical composition of dust transported from Africa by setting up an orchestra of aerosol sampling devices in the strategic archipelago of Cape Verde; 2) to identify the sources of particles in Cape Verde by using receptor models; 3) to elucidate the role Saharan dust may play in the degradation of Cape Verde air quality; 4) to model processes governing dust production, transport, interaction with the radiation field and removal from the atmosphere. Here we present part of the data obtained throughout the last year, involving a set of more

    The disproportionate species richness of the world's biodiversity hotspots could be explained by low extinction (the evolutionary "museum") and/or high speciation (the "hot-bed") models. We test these models using the largest of the species rich plant groups that characterise the botanically diverse Cape Floristic Region (CFR): the genus Erica L. We generate a novel phylogenetic hypothesis informed by nuclear and plastid DNA sequences of c. 60 % of the c. 800 Erica species (of which 690 are endemic to the CFR), and use this to estimate clade ages (using RELTIME; BEAST), net diversification rates (GEIGER), and shifts in rates of diversification in different areas (BAMM; MuSSE). The diversity of Erica species in the CFR is the result of a single radiation within the last c. 15 million years. Compared to ancestral lineages in the Palearctic, the rate of speciation accelerated across Africa and Madagascar, with a further burst of speciation within the CFR that also exceeds the net diversification rates of other Cape clades. Erica exemplifies the "hotbed" model of assemblage through recent speciation, implying that with the advent of the modern Cape a multitude of new niches opened and were successively occupied through local species diversification.

  8. Simulated precipitation diurnal cycles over East Asia using different CAPE-based convective closure schemes in WRF model

    Closure assumption in convection parameterization is critical for reasonably modeling the precipitation diurnal variation in climate models. This study evaluates the precipitation diurnal cycles over East Asia during the summer of 2008 simulated with three convective available potential energy (CAPE) based closure assumptions, i.e. CAPE-relaxing (CR), quasi-equilibrium (QE), and free-troposphere QE (FTQE) and investigates the impacts of planetary boundary layer (PBL) mixing, advection, and radiation on the simulation by using the weather research and forecasting model. The sensitivity of precipitation diurnal cycle to PBL vertical resolution is also examined. Results show that the precipitation diurnal cycles simulated with different closures all exhibit large biases over land and the simulation with FTQE closure agrees best with observation. In the simulation with QE closure, the intensified PBL mixing after sunrise is responsible for the late-morning peak of convective precipitation, while in the simulation with FTQE closure, convective precipitation is mainly controlled by advection cooling. The relative contributions of different processes to precipitation formation are functions of rainfall intensity. In the simulation with CR closure, the dynamical equilibrium in the free troposphere still can be reached, implying the complex cause-effect relationship between atmospheric motion and convection. For simulations in which total CAPE is consumed for the closures, daytime precipitation decreases with increased PBL resolution because thinner model layer produces lower convection starting layer, leading to stronger downdraft cooling and CAPE consumption. The sensitivity of the diurnal peak time of precipitation to closure assumption can also be modulated by changes in PBL vertical resolution. The results of this study help us better understand the impacts of various processes on the precipitation diurnal cycle simulation.

    Women with disabilities are at disproportionate risk for adverse pregnancy outcomes, however, there is limited information on their pregnancy histories. This mixed-methods study focuses on signing Deaf women whose access to health care may be compromised by language barriers related to their disability. To describe and compare the pregnancy outcomes and maternity service use of a sample of signing Deaf women of child-bearing age in Cape Town to the population of the Western Cape of South Africa. We interviewed 42 Deaf women selected by non-probability snowball sampling, using a structured questionnaire in South African Sign Language in Cape Town in July 2016. Average parity of the sample was similar to that of the Western Cape population. Most women had one or two children (74%). Thirty-one percent of women had experienced a miscarriage and 19% had terminated a pregnancy. Almost all women (96%) attended at least one antenatal appointment during their pregnancies, and all deliveries occurred at a health facility. Women primarily relied on writing to communicate during antenatal visits and labor/delivery. The majority of women reported communication issues due to limited interpretation services, and some reported experiencing mistreatment from hospital staff. This study provides novel information on the pregnancy histories of Deaf women. While maternal service usage was high, the quality of services were inadequate with reports of linguistic barriers and mistreatment. Findings suggest the need to improve maternity care for Deaf women through implementing interpretation services and providing sensitivity training to health care providers.

    According to World Health Organization (WHO) estimates, the under-reporting rate for tuberculosis (TB) in Cape Verde between 2006 and 2012 was 49%. However, the WHO recognises the challenges associated with this estimation process and recommends implementing other methods, such as record linkage, to combat TB under-reporting. To estimate and analyse under-reporting of cases by TB surveillance health units and to evaluate TB cases retrieved from other TB diagnostic sources in Praia, Cape Verde, from 2006 to 2012. This cross-sectional study evaluated under-reporting using the following data: 1) the under-reporting index from TB reporting health units (RHUs), where the number of validated TB cases from RHUs was compared with data from the National Programme for the Fight against Tuberculosis and Leprosy (NPFTL); and 2) the under-reporting index among overall data sources, or a comparison of the number of all validated TB cases from all sources with NPFTL data. The TB under-reporting rate was 40% in Praia during the study period, and results were influenced by laboratory findings. The TB under-reporting rate was very similar to the rate estimated by the WHO. TB surveillance must be improved to reduce under-reporting.

  1. Mourning Mandela: sacred drama and digital visuality in Cape Town

    Directory of Open Access Journals (Sweden)

    Paula Uimonen

    2015-12-01

    Full Text Available The world united in unprecedented ways in mourning the global icon Nelson Mandela, an emotionally charged historical event in which digital visuality played an influential role. The memorial service for Nelson Mandela on Tuesday, 10 December 2013, gathered dignitaries and celebrities from around the world at the First National Bank Stadium in Johannesburg, to mourn the passing of Madiba and to celebrate his life work. At the Grand Parade in Cape Town, the event was broadcast on large public screens, followed by live music performances and narrowcast interaction with the audience. Building on recent research on public screens during global media events, this article addresses the mediated mourning rituals at the Grand Parade in terms of a sacred drama. Focusing on social relationality, the article discusses how digital visuality mediated a sense of global communitas, thus momentarily overcoming historical frictions between the global north and the global south, while expanding the fame of Madiba. Paying attention to the public display of visual memory objects and the emotional agency of images, it argues that digital visuality mediated social frictions between the living and the dead, while recasting a historical subject as a historical object. The article further discusses how digital visuality mediated cultural frictions of apartheid and xenophobia, through the positioning of Mandela in the pantheon of Pan-African icons, thus underlining the African origin of this global icon. The analysis is based on ethnographic observations and experiences in Cape Town.

  4. Comparative life history of the south temperate Cape Penduline Tit (Anthoscopus minutus) and north temperate Remizidae species

    Science.gov (United States)

    Lloyd, Penn; Frauenknecht, Bernhard D.; du Plessis, Morné A.; Martin, Thomas E.

    2017-01-01

    We studied the breeding biology of the south temperate Cape Penduline Tit (Anthoscopus minutus) in order to compare its life history traits with those of related north temperate members of the family Remizidae, namely the Eurasian Penduline Tit (Remiz pendulinus) and the Verdin (Auriparus flaviceps). We used this comparison to test key predictions of three hypotheses thought to explain latitudinal variation in life histories among bird species—the seasonality and food limitation hypothesis, nest predation hypothesis and adult mortality hypothesis. Contrary to the general pattern of smaller clutch size and lower adult mortality among south-temperate birds living in less seasonal environments, the Cape Penduline Tit has a clutch size larger than that of the Verdin and similar to that of the Eurasian Penduline Tit, and higher adult mortality than both of the other two species. The most notable difference between the Cape Penduline Tit and the two other species is in parental behavioural strategy, with the former exhibiting bi-parental care at all stages of nesting together with facultative cooperative breeding, whereas the Eurasian Penduline Tit has uni-parental care and the Verdin has a combination of female-only incubation but bi-parental nestling care. Consequently, in comparison to the other two species, the Cape Penduline Tit exhibits greater nest attentiveness during incubation, a similar per-nestling feeding rate and greater post-fledging survival. Its relatively large clutch size, high parental investment and associated high adult mortality in a less seasonal environment are consistent with key predictions of the adult mortality hypothesis but not with key predictions of the seasonality and food limitation hypothesis in explaining life history variation among Remizidae species. These results add to a growing body of evidence of the importance of age-specific mortality in shaping life history evolution.

  5. Feasibility of eradicating Ceratitis spp. fruit flies from the Western Cape of South Africa by the sterile insect technique

    Fruit production (deciduous fruit, table and wine grapes, and citrus) is a major export-based industry in the Western Cape, with more than 200,000 ha under cultivation. The gross value of these fruits (excluding wine) exceeds US$400 million per annum. Deciduous fruit and table grapes make up the major portion of the industry, with approximately 110,000 ha under production. The Western Cape is host to two species of fruit flies, the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), and the Natal fruit fly, C. rosa Karsch. One or both of these species attack at least 19 species of fruits in this area. Both species have very similar life cycles and habits, and can cause enormous crop losses especially to fruits, but also to some vegetables. Both commercial and resource-limited farmers are affected by fruit flies. Control of fruit flies is currently based on ground applications of insecticides, either as full-cover foliar sprays or low-volume bait sprays. Control costs and crop losses for deciduous fruit and table grapes alone are estimated at US$4 million annually. South Africa is the only southern hemisphere deciduous fruit-exporting country that is not fruit fly-free or is not currently engaged in a project to eradicate fruit flies. Unless similar steps are taken, this situation is likely to threaten the competitiveness of the Western Cape's industry. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture of the United Nations recently approved funding for the INFRUITEC Centre of the ARC-Fruit, Vine and Wine Research Institute in Stellenbosch to undertake a study to determine the feasibility of eradicating fruit flies from the Western Cape by the sterile insect technique (SIT). Most fruits in the Western Cape are produced in valley systems, and many valleys are isolated from one another to a greater or lesser extent. The Western Cape is itself well isolated from other areas with fruit fly hosts: by the ocean on the eastern, southern and

    The 2004 Indian Ocean tsunami had notable impacts on coastal landforms. Temporal change in topography by coastal erosion and subsequent formation of a new barrier spit on the nearshore of Pakrang Cape, southeastern Thailand, had been monitored for 10 years since 2005 based on field measurement using satellite images, high-resolution differential GPS, and/or handy GPS. Monitored topography data show that a barrier island was formed offshore from the cape several months after the tsunami event through progradation of multiple elongated gravelly beach ridges and washover fan composed of coral gravels. Subsequently, the barrier spit expanded to the open sea. The progradation and expansion were supported by supply of a large amount of coral debris produced by the tsunami waves. These observations provide useful data to elucidate processes of change in coastal landforms after a tsunami event. The 2004 Indian Ocean tsunami played an important role in barrier spit evolution over a period of at least a decade.

    2018-04-01

    We report new discoveries and radiocarbon dates on active and abandoned Adélie penguin ( Pygoscelis adeliae ) colonies at Cape Adare, Antarctica. This colony, first established at approximately 2000 BP (calendar years before present, i.e. 1950), is currently the largest for this species with approximately 338 000 breeding pairs, most located on low-lying Ridley Beach. We hypothesize that this colony first formed after fast ice began blocking open-water access by breeding penguins to the Scott Coast in the southern Ross Sea during a cooling period also at approximately 2000 BP. Our results suggest that the new colony at Cape Adare continued to grow, expanding to a large upper terrace above Ridley Beach, until it exceeded approximately 500 000 breeding pairs (a 'supercolony') by approximately 1200 BP. The high marine productivity associated with the Ross Sea polynya and continental shelf break supported this growth, but the colony collapsed to its present size for unknown reasons after approximately 1200 BP. Ridley Beach will probably be abandoned in the near future due to rising sea level in this region. We predict that penguins will retreat to higher elevations at Cape Adare and that the Scott Coast will be reoccupied by breeding penguins as fast ice continues to dissipate earlier each summer, restoring open-water access to beaches there.

    Full Text Available While ward committees and Integrated Development Planning (IDP representative forums constitute formal participatory mechanisms in South Africa’s local government, little is known about the potential of local approaches in enhancing participation in municipal planning. This paper examines alternative approaches to participation based on research conducted in Langa – a township situated on the Cape Flats of Cape Town. The paper highlights approaches to residents’ participation in planning tested during the ‘interregnum’ – the period when ward committees are in abeyance due to elections. The study found that, while IDP participatory processes facilitated awareness of participation, ward councillors were crucial in operationalising participation that reflects the diversity of the community.

    The Cape Fold Belt and Karoo Basin of southern Africa formed during the Permian orogeny that affected the 13,000 km southern margin of the Gondwanan continent. In this report, we synthesize new and recent magnetostratigraphic and geochronologic data to establish a chronostratigraphic framework for Karoo Basin sedimentation for comparison with the thermal/exhumation history of the Cape Fold Belt. The source-sink model is evaluated using new data from detrital muscovite and zircon from 2 km composite section of fluvial sandstone and mudstones deposited at ca.275 - 260 Ma. Coherent age populations of detrital zircon grains indicate rapid incorporation of contemporary volcanic ashbeds into the sedimentary record. In contrast, cooling age distributions of detrital muscovite are typically ca. 5 - 10 Ma older than the age of deposition; similar lag times are observed from modern sediments in active mountain belts. Trace element geochemical signatures demonstrate a clear shift towards crustal recycling via headland erosion in the Beaufort Group relative to the underlying Ecca Group. These observations pinpoint the age of uplift for the Cape Fold Belt, which began to function as the major sediment source for the foreland Karoo Basin with the deposition of the uppermost Ecca Group and basal Beaufort Group.

    Full Text Available Developing countries are faced with the problem of improper treatment and disposal of human excreta due to the use of unimproved sanitation systems. In an attempt to increase access to sanitation facilities many governments have adopted public latrines. Field experience has shown that public latrines have the problem of high usage rate and the use of non-degradable anal cleansing materials leading to the filling up of the pits much faster than their design life. This research therefore seeks to assess the usage and management practices excreta degradation and desludging rate of public dry on-site sanitation systems in the Cape Coast Metropolis. Thirteen 13 public Ventilated Improved Pit latrines located in the Cape Coast metropolis were selected. Structured interview was conducted to determine the usage rate desludging frequency and user practices of the public latrines. The results show that the usage rate of public dry latrines in the Cape Coast metropolis is low 9 25 personssquat hole but the desludging rate is high 7 120 days. The high desludging frequency is attributed to the addition of non biodegradable materials and less microbial activity due to the excessive use of disinfectants.

    Full Text Available Dehydrated products added with active components (AC represent a healthy alternative for modern consumer. The aim of this research was to evaluate the influence of drying process conditions on the physiological quality attributes of cape gooseberry (Physalis peruviana L. impregnated under vacuum with AC and dehydrated. A factorial design was performed with two independent variables, 2 levels per variable (temperature: 50 and 60ºC, air velocity: 2.0 and 3.0 m.s-1 and three replicates per drying condition. In fact, cape gooseberry fruits were previously impregnated under vacuum with an emulsion containing calcium and vitamins B9, C, D3 and E, which were subjected to dehydration until a water activity of approximately 0.6. In addition, drying rate curves presented in all cases two periods of decreasing speed. An increase of drying temperature decreases the processing time, presenting a greater AC degradation, while the air velocity offers a non-significant effect. The treatment which have allowed an AC better retention and low processing times was 60° C and 2 m.s-1, reaching levels of 204.8 ± 10.5 mg, 137.0 ± 34.7 μg, 13.6 ± 0.9 mg, 2.2± 0.6 μg, 7.0±1.2 mg for calcium and vitamins B9, C, D3 and E, respectively per 50 g serving of dehydrated cape gooseberry. An integration of the vacuum impregnation process with conventional air-drying, represents an effective technological alternative, which confers a higher added value to cape gooseberry fruit.

    Malaria, despite being preventable and treatable, continues to be a major public health problem worldwide. The archipelago nation of Cape Verde is in a malaria pre-elimination phase with the highest potential to achieve the target goal of elimination in 2020. Nationwide malaria epidemiological data were obtained from the Cape Verde health information system that includes the individual malaria case notification system from all of the country's health structures. Each case is reported to the surveillance service then to the National Malaria Control Programme, which allowed for compilation in the national malaria case database. The database was analysed to assess the origin of the malaria cases, and incidence was calculated from 2010 to 2016 by sex and age. The health centre, health district and month of diagnosis were evaluated, as well as the sex and the age of the patients, allowing a direct descriptive analysis of national data to provide an up-to-date malaria epidemiological profile of the country. Malaria cases were classified as imported or indigenous, and then, geographical analyses were performed using a unique Geographical National Code with Quantum Geographic Information System 2.16.2 software to map the cases by municipalities. The overall temporal evolution of cases was analysed to assess their monthly and yearly variations from 2010 to 2016. Malaria is unstable in Cape Verde, with inter-annual variation and the majority of infections occurring in adult males (> 20 years). The indigenous cases are restricted to Santiago (96%) and Boavista (4%), while imported cases were recorded in all the nine inhabited islands, originating from neighbouring countries with ongoing malaria transmission; from Lusophone countries (25% from Angola, 25% from Guinea-Bissau), followed by the Republic of Senegal (12%) and Equatorial Guinea (10%). In 2010-2012, more imported (93 cases) than indigenous cases (26 cases) were observed; conversely, in 2013 and 2014, more

    Leptospirosis is an important worldwide zoonotic disease that can infect both animals and humans. In most cases, leptospirosis is a nonspecific self-limiting illness, but some patients can develop a severe form with a high mortality. This study was carried out in Santiago Island, Cape Verde, in 2012-2013. A total of 62 wild rodents (Rattus rattus and Mus domesticus) were analyzed. The lipL32 gene, present only in pathogenic Leptospira spp., was amplified by PCR, and 16 samples were positive (25.8%). In both rodent species, Leptospira interrogans was identified. The results show the presence of pathogenic Leptospira in the three localities analyzed in Santiago. The presence of L. interrogans demonstrates a serious health risk for the population, since this species has been associated with the most severe form of leptospirosis, the Weil's disease in humans, a severe infection with jaundice, renal failure, and hemorrhage.

    Full Text Available Comprising an area of ± 90 000 km:, less than 5% of the land surface of the southern African subcontinent, the Cape Floristic Region (CFR is one of the world’s richest areas for plant species diversity. A recent synoptic flora for the Region has established a new base line for an accurate assessment of the flora. Here we document corrections and additions to the flora at family, genus and species ranks. As treated in Cape plants, which was completed in 1999. the flora comprised 173 families (five endemic, 988 genera (160 endemic: 16.2%, and 9 004 species (6 192 endemic: 68.8%. Just four years later, a revised count resulting from changes in the circumscriptions of families and genera, and the discovery of new species or range extensions of species, yields an estimate of 172 families (four endemic, 992 genera (162 endemic: 16.3% and 9 086 species (6 226: 68.5% endemic. Of these, 948 genera and 8 971 species are seed plants. The number of species packed into so small an area is remarkable for the temperate zone and compares favourably with species richness for areas of compa­rable size in the wet tropics. The degree of endemism is also remarkable for a continental area. An unusual family compo­sition includes, in descending order of size, based on species number. Asteraceae. Fabaceae. Iridaceae. Ericaceae. Aizoaceae, Scrophulariaceae. Proteaceae. Restionaceae, Rutaceae. and Orchidaceae. Disproportionate radiation has resulted in 59.1% of the species falling in the 10 largest families and 74.6% in the largest 20 families. Thirteen genera have more than 100 species and the 20 largest genera contribute some 31.5% of the total species number.

    2010-01-01

    Full Text Available The article reports on an investigation of the provision of gay and lesbian literature and of information services to gays and lesbians in Cape Town’s public libraries. Although by definition public libraries serve all members of a community, the international literature suggests that they neglect the reading and information needs and interests of gays and lesbians. The progressive South African Constitution views the rights of gays and lesbians as human rights; yet homophobia is prevalent. Using a questionnaire, the study explored attitudes and practices of 69 senior librarians, responsible for collection development, across all six of Cape Town’s library districts. The situation was found to be “spotty” with only 26 respondents believing that their library service is meeting the needs of gays and lesbians. The survey found contradictions between stated beliefs and behaviours. Thus, although most agree that LGBT rights to information and equal services are human rights, only 55% consider LGBT people in their selection procedures and very little material is acquired. Information services are thin with, for example, only 10% of the libraries in the survey providing LGBT related information in their community information files.

    2013-04-01

    Full Text Available Colombia is the world’s leading producer of the cape gooseberry and it is a crop of great importance due to its high demand in the international market. The fruit, the part that is sold, is an ovoid-shaped, juicy berry, and its harvest starts when the fruit is orange-colored and the cap surrounding the fruit is yellowcolored. This labor is done manually. During this phase of collection, subsequent handling and transport to the places of packaging and marketing, the fruit is subjected to multiple loads which may deteriorate it in different ways, resulting in significant product losses. Rheological tests of unidirectional compression, punctures, and cuts at the peduncle were performed in order to characterize the mechanical response of the fruit to the type of forces exerted at harvest and post-harvest handling. It was found that the fruit’s firmness in unidirectional compression in the axial direction, with a ripeness grade of four, was 38.6 N, while the force required to separate the fruit from the peduncle was 15.1 N. The mechanical behavior of the cape gooseberry corresponds to a viscoelastic, anisotropic, highly variable material

    Full Text Available This paper investigates the suitable location for an intermodal inland container terminal (IICT in the city of Cape Town. A container market segmentation approach is used to project growth for container volumes over a 30-year period for all origin and destination pairings on a geographical district level in an identified catchment area. The segmentation guides the decision on what type of facility is necessary to fulfil capacity requirements in the catchment area and will be used to determine the maximum space requirements for a future IICT. Alternative sites are ranked from most suitable to least suitable using multi-criteria analysis, and preferred locations are identified. Currently, South Africa’s freight movement is dominated by the road sector. Heavy road congestion is thus prevalent at the Cape Town Container Terminal (CTCT. The paper proposes three possible alternative sites for an IICT that will focus on a hub-and-spoke system of transporting freight.

    Two new species of Indigofera L. (Leguminosae) are described from the Sneeuberg Centre of Floristic Endemism on the southern Great Escarpment, Eastern and Western Cape Provinces, South Africa. Both species are localised high-altitude endemics. Indigoferamagnifica Schrire & V.R. Clark is confined to the summit plateau of the Toorberg-Koudeveldberg-Meelberg west of Graaff-Reinet, and complements other western Sneeuberg endemics such as Ericapasserinoides (Bolus) E.G.H. Oliv. and Faurearecondita Rourke & V.R. Clark. Indigoferaasantasanensis Schrire & V.R. Clark is confined to a small area east of Graaff-Reinet, and complements several other eastern Sneeuberg endemics such as Euryopsexsudans B. Nord & V.R. Clark and Euryopsproteoides B. Nord. & V.R. Clark. Based on morphology, both new species belong to the Cape Clade of Indigofera, supporting a biogeographical link between the Cape Floristic Region and the Sneeuberg, as well as with the rest of the eastern Great Escarpment.

    Fernandes, R. M. S.; Faria, B. V. E.

    2015-12-01

    The Fogo volcano, located in the Cape Verde Archipelago (offshore Western Africa), is a complete stratovolcano system. It is the most recent expression of the Cape Verde hotspot, that has formed the archipelago. The summit reaches ~2830m above sea level, and raises 1100m above Chã das Caldeiras, an almost flat circular area. The last eruption of Fogo started on November 23, 2014 (~10:00UTC), after 19 years of inactivity. C4G, a distributed research infrastructure created in 2014 in the framework of the Portuguese Roadmap for Strategic Research Infrastructures, collaborated immediately with INMG, the Cape Verdean Meteorological and Geophysical Institut with the goal of complementing the permanent geophysical monitoring network in operation on Fogo island. The INMG permanent network is composed of seven seismographic stations and three tiltmeter stations, with real-time data transmitted. On the basis of increased pre-event activity (which started in October 2014), INMG issued a formal alert of an impending eruption to the Civil Protection Agency, about 24 hours before the onset of the eruption. Although the eruption caused no casualties or personal injuries due to the warnings issued, the lava expelled by the eruption (which last until the end of January) destroyed the two main villages in the caldera (~1000 inhabitants) and covered vast areas of agricultural land, causing very large economic losses and an uncertain future of the local populations. The C4G team installed a network of seven GNSS receivers and nine seismometers, distributed by the entire island. The data collection started on 28th November 2014, and continued until the end of January 2015. The mission also included a new detailed gravimetric survey of the island, the acquisition of geological samples, and the analysis of the air quality during the eruption. We present here a detailed description of the monitoring efforts carried out during the eruption as well as initial results of the analysis of the

  2. Chemistry of volcanic soils used for agriculture in Brava Island (Cape Verde)

    Brava is a small volcanic island located on the south-western part of the Cape Verde archipelago. It is characterized by an irregular plateau between 300 and 976 m above sea level, which is bounded by steep coastal cliffs and cut by fluvial incision in a generally radial drainage pattern. The major volcano-stratigraphic units of the island are: Lower Unit, Middle Unit, Upper Unit, and Sediments. Although Brava is one of the islands with more frequent rainy periods in Cape Verde, the climate is essentially semi-arid, which associated with the rough topography leads to incipient soils. Detailed Fe speciation and chemical composition studies of Cape Verde soils have shown that oxidation is a major weathering mechanism, and high contents of trace elements may occur originated from imbalance of elements in the volcanic parent materials, which can be a threat to the environmental health. The soils mostly used for agriculture in Brava Island are those developed on phonolitic pyroclasts on the plateau and also on sediments. In this work the whole sample (< 2 mm) and the clay-sized fraction (< 2 µm) of these soils were analysed by Mössbauer spectroscopy and neutron activation analysis, aiming to characterize the iron speciation and to determine the concentration and distribution of 30 chemical elements in Brava soils. Mössbauer spectroscopy shows that Fe is more oxidyzed in topsoils developed on sediments (84-87%) than in soils developed on pyroclasts (71-79%). In the clay sized-fraction of all the studied soils only Fe(III) was detected. Iron oxides clearly distinguish the soils derived from the two types of parent materials, hematite being the only Fe oxide present in soils developed on sediments, while maghemite is more abundant in soils developed on pyroclasts. Iron and chromium are depleted in this fine fraction suggesting their occurrence as iron oxides and ferromagnesian minerals present in coarser particles. Among the chemical elements studied, antimony was found

    Full Text Available Inter-racial differences in disease characteristics and in the management of Crohn's disease (CD have been described in African American and Asian subjects, however for the racial groups in South Africa, no such recent literature exists.A cross sectional study of all consecutive CD patients seen at 2 large inflammatory bowel disease (IBD referral centers in the Western Cape, South Africa between September 2011 and January 2013 was performed. Numerous demographic and clinical variables at diagnosis and date of study enrolment were identified using an investigator administered questionnaire as well as clinical examination and patient case notes. Using predefined definitions, disease behavior was stratified as 'complicated' or 'uncomplicated'.One hundred and ninety four CD subjects were identified; 35 (18% were white, 152 (78% were Cape Coloured and 7(4% were black. On multiple logistic regression analysis Cape Coloureds were significantly more likely to develop 'complicated' CD (60% vs. 9%, p = 0.023 during the disease course when compared to white subjects. In addition, significantly more white subjects had successfully discontinued cigarette smoking at study enrolment (31% vs. 7% reduction, p = 0.02. No additional inter-racial differences were found. A low proportion of IBD family history was observed among the non-white subjects.Cape Coloured patients were significantly more likely to develop 'complicated' CD over time when compared to whites.

    2017-04-01

    The Cape bee is endemic to the winter rainfall region of South Africa where fires are an integral part of the ecology of the fynbos (heathland) vegetation. Of the 37 wild nests in pristine Peninsula Sandstone Fynbos in the Cape Point section of Table Mountain National Park that have been analyzed so far, only 22 could be accessed sufficiently to determine the existence of a propolis wall of which 68% had propolis walls which entirely enclosed their openings. The analysis of the 37 wild nests revealed that 78% occurred under boulders or in clefts within rocks, 11% in the ground, 8% in tree cavities, and 3% within shrubs. The analysis of 17 of these nests following a fire within the park revealed that the propolis walls materially protected the nests and retarded the fire with all the colonies surviving. The bees responded to the smoke by imbibing honey and retreating to the furthest recess of their nest cavity. The bees were required to utilize this honey for about 3 weeks after which fire-loving plants appeared and began flowering. Considerable resources were utilized in the construction of the propolis walls, which ranged in thickness from 1.5 to 40 mm (mean 5 mm). Its physical environment determines the nesting behavior of the Cape bee. The prolific use of propolis serves to insulate the nest from extremes of temperature and humidity, restricts entry, camouflages the nest, and acts as an effective fire barrier protecting nests established mostly under rocks in vegetation subjected to periodic fires.

    2018-05-05

    The Cape Verde islands are part of the African Sahelian arid belt that possesses an erratic rain pattern prompting the need for water reservoirs, which are now critical for the country’s sustainability. Worldwide, freshwater cyanobacterial blooms are increasing in frequency due to global climate change and the eutrophication of water bodies, particularly in reservoirs. To date, there have been no risk assessments of cyanobacterial toxin production in these man-made structures. We evaluated this potential risk using 16S rRNA gene amplicon sequencing and full metagenome sequencing in freshwater reservoirs of Cape Verde. Our analysis revealed the presence of several potentially toxic cyanobacterial genera in all sampled reservoirs. Faveta potentially toxic and bloom-forming Microcystis sp., dominated our samples, while a Cryptomonas green algae and Gammaproteobacteria dominated Saquinho and Poilão reservoirs. We reconstructed and assembled the Microcystis genome, extracted from the metagenome of bulk DNA from Faveta water. Phylogenetic analysis of Microcystis cf. aeruginosa CV01’s genome revealed its close relationship with other Microcystis genomes, as well as clustering with other continental African strains, suggesting geographical coherency. In addition, it revealed several clusters of known toxin-producing genes. This survey reinforces the need to better understand the country’s microbial ecology as a whole of water reservoirs on the rise.

    Full Text Available Stroke is a leading cause of death and a major cause of disability globally. Individuals with physical disabilities, including thosewho have suffered a stroke are at risk of secondary complications due to the impact of their disability, which may be exacerbated by their lifestylechoices. The aim of the present study was to determine the health riskbehaviours and factors that influence these behaviours of stroke patients inthe Metropole Region of the Western Cape, South Africa. A cross – sectionalsurvey, utilizing a self-administered questionnaire on a convenient sampleof 417 stroke patients, was used to collect data. A sub-sample of 10 parti-cipants was purposively selected for in-depth, face-to-face interviews.Approximately forty percent (40.3% of the participants did not engage in physical exercise. While 30.2% smoked only9% abused alcohol. A significant association was found between age and smoking (p<0.002. Information gathered in the in-depth interviews revealed factors that influenced the behaviours of the participants. These factors includedlack of financial resources and lack of access to information. As participants were found to be at risk of secondarycomplications because of poor lifestyle choices, there is a clear need to implement health promotion programmes topromote well-ness enhancing behaviours in order to enhance the quality of health of patients who have suffered astroke in the Western Cape, South Africa.

    1996-01-01

    Spirochetes from microbial mats and anaerobic mud samples collected in salt marshes were studied by light microscopy, whole mount and thin section transmission electron microscopy. Enriched in cellobiose-rifampin medium, selective for Spirochaeta bajacaliforniensis, seven distinguishable spirochete morphotypes were observed. Their diameters ranged from 0.17 micron to > 0.45 micron. Six of these morphotypes came from southwest Cape Cod, Massachusetts: five from Microcoleus-dominated mat samples collected at Sippewissett salt marsh and one from anoxic mud collected at School Street salt marsh (on the east side of Eel Pond). The seventh morphotype was enriched from anoxic mud sampled from the north central Cape Cod, at the Sandy Neck salt marsh. Five of these morphotypes are similar or identical to previously described spirochetes (Leptospira, Spirochaeta halophila, Spirochaeta bajacaliforniensis, Spirosymplokos deltaeiberi and Treponema), whereas the other two have unique features that suggest they have not been previously described. One of the morphotypes resembles Spirosymplokos deltaeiberi (the largest free-living spirochete described), in its large variable diameter (0.4-3.0 microns), cytoplasmic granules, and spherical (round) bodies with composite structure. This resemblance permits its tentative identification as a Sippewissett strain of Spirosymplokos deltaeiberi. Microbial mats samples collected in sterile Petri dishes and stored dry for more than four years yielded many organisms upon rewetting, including small unidentified spirochetes in at least 4 out of 100 enrichments.

    2011-06-01

    The rates of Foetal Alcohol Syndrome (FAS) and Partial Foetal Alcohol Spectrum (PFAS) in South Africa are the highest reported worldwide. There is a paucity of research examining the health care costs of caring for children with FAS or PFAS in this country. A cross-sectional analytical study was conducted using an interviewer-administered questionnaire amongst caregivers of children (0-12 years) with FAS/PFAS in the Western Cape to estimate the utilization of health care services; the annual direct and indirect health care costs per child as well as the total cost to society for providing health care services to children with FAS/PFAS. It was found that the median number of annual visits to public health care facilities per child was 8 (IQR 4 to 14). The total average annual cost per child was $1039.38 (95% CI: $808.68; $1270.07) and the total annual societal cost for the Western Cape was $70,960,053.68 (95% CI: $5,528,895.48; $86,709,971.13). Caregivers in receipt of a social support grant reported spending significantly less on health care for a child with FAS/PFAS (Fisher's exact p=0.004). These study results confirm the significant burden of FAS/PFAS on the Western Cape economy and the health care system which has significant implications for FAS prevention.

    The Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission was recommended by the National Research Council's (NRC's) Earth Science Decadal Survey to measure tropospheric trace gases and aerosols and coastal ocean phytoplankton, water quality, and biogeochemistry from geostationary orbit, providing continuous observations within the field of view. To fulfill the mandate and address the challenge put forth by the NRC, two GEO-CAPE Science Working Groups (SWGs), representing the atmospheric composition and ocean color disciplines, have developed realistic science objectives using input drawn from several community workshops. The GEO-CAPE mission will take advantage of this revolutionary advance in temporal frequency for both of these disciplines. Multiple observations per day are required to explore the physical, chemical, and dynamical processes that determine tropospheric composition and air quality over spatial scales ranging from urban to continental, and over temporal scales ranging from diurnal to seasonal. Likewise, high-frequency satellite observations are critical to studying and quantifying biological, chemical, and physical processes within the coastal ocean. These observations are to be achieved from a vantage point near 95deg-100degW, providing a complete view of North America as well as the adjacent oceans. The SWGs have also endorsed the concept of phased implementation using commercial satellites to reduce mission risk and cost. GEO-CAPE will join the global constellation of geostationary atmospheric chemistry and coastal ocean color sensors planned to be in orbit in the 2020 time frame.

Cape Town became a cosmopolitan settlement with different categories of people, amongst them a non-European underclass that consisted of slaves, exiles, convicts and free-blacks. This study integrated new strontium isotope data with carbon and nitrogen isotope results from an 18th-19th century burial ground at Cobern Street, Cape Town, to identify non-European forced migrants to the Cape.

    This study explores the lived experience of being a Speech-Language Therapist (S-L Therapist) in the South African Western Cape public health service. The lived experience of seven S-L Therapists with varied clinical experience was illuminated using a qualitative phenomenological research design. S-L Therapists, working in the three Western Cape tertiary hospitals, provided an in-depth account of their experiences as S-L Therapists. The audio recorded interviews were transcribed verbatim and analysed using an adaptation of Colaizzi's (1978) method of analysis. The rigour and trustworthiness of the research process was informed by consideration of issues of credibility, applicability, confirmability and dependability as they relate to phenomenological design. Five main themes emerged from data analysis: expectations of practice and practice realities; being part of the "underdog" profession: role definition and status; being connected; the holistic nature of the S-L Therapist's practice; and erosion or promotion.The implications for training and support of S-L Therapists by managers and policymakers and peers are highlighted.

    The 'Health Belief Model' (HBM) identifies perception of HIV/AIDS risks, recognition of its seriousness, and knowledge about prevention as predictors of safer sexual activity. Using data from the Cape Area Panel Survey (CAPS) and hazard models, this study examines the impact of risk perception, considered the first step in HIV prevention, set within the context of the HBM and socio-economic, familial and school factors, on the timing of first sexual intercourse among youth aged 14-22 in Cape Town, South Africa. Of the HBM components, female youth who perceive their risk as 'very small' and males with higher knowledge, experience their sexual debut later than comparison groups, net of other influences. For both males and females socio-economic and familial factors also influence timing of sexual debut, confirming the need to consider the social embeddedness of this sexual behavior as well as the rational components of decision making when designing prevention programs.

    Large Marine Ecosystems such as the Canary Current system off West Africa sustains high abundance of small pelagic prey, which attracts marine predators. Seabirds are top predators often used as biodiversity surrogates and sentinel species of the marine ecosystem health, thus frequently informing marine conservation planning. This study presents the first data on the spatial (GPS-loggers) and trophic (stable isotope analysis) ecology of a tropical seabird-the endangered Cape Verde shearwater Calonectris edwardsii-during both the incubation and the chick-rearing periods of two consecutive years. This information was related with marine environmental predictors (species distribution models), existent areas of conservation concern for seabirds (i.e. marine Important Bird Areas; marine IBAs) and threats to the marine environment in the West African areas heavily used by the shearwaters. There was an apparent inter-annual consistency on the spatial, foraging and trophic ecology of Cape Verde shearwater, but a strong alteration on the foraging strategies of adult breeders among breeding phases (i.e. from incubation to chick-rearing). During incubation, birds mostly targeted a discrete region off West Africa, known by its enhanced productivity profile and thus also highly exploited by international industrial fishery fleets. When chick-rearing, adults exploited the comparatively less productive tropical environment within the islands of Cape Verde, at relatively close distance from their breeding colony. The species enlarged its trophic niche and increased the trophic level of their prey from incubation to chick-rearing, likely to provision their chicks with a more diversified and better quality diet. There was a high overlap between the Cape Verde shearwaters foraging areas with those of European shearwater species that overwinter in this area and known areas of megafauna bycatch off West Africa, but very little overlap with existing Marine Important Bird Areas.

    Full Text Available The Bo-Kaap is an older inner-city, working-class neighbourhood in Cape Town, South Africa. By the 1930s, the area had degenerated into an overcrowded and run-down neighbourhood, consisting largely of dilapidated houses, but by 1941 about 150 housing units had been expropriated by the local authority for redevelopment in a comprehensive renewal scheme for the area. However, the process was halted with the formation of the so-called “Group for the Preservation of the Malay Quarter”, which fought against the demolition of the houses. At present, the area with its colourful housing units and 11 mosques is part of Cape Town’s cultural heritage and a very important tourist attraction. As in the case of De Waterkant, a gentrified neighbourhood adjacent to it, the area has seen a large number of housing units renovated and upgraded. Property prices have increased dramatically, although they are still relatively low, while the number of properties sold is also on the rise – so much so that the community leaders and especially the Muslim residents are in a constant battle to preserve the neighbourhood’s cultural identity.

    Full Text Available Patterns in species richness of 23 small, isolated forests on the inland mountains of the southern Cape were studied. Species richness of woody plants and vines of the Kouga-Baviaanskloof Forests was higher than in the western mountain complexes, where species richness in the more southern Rooiberg and Kamanassie Mountains was higher than in the Swartberg range. The Rooiberg, a dry mountain with small forests far away from the coastal source area, had more species than, and contained many species which are absent from, the larger, moister forests of the Kamanassie which are closest to the coastal source areas. Neither altitude nor distance from the source area, the forests south of the coastal mountains, nor long-distance dispersal, adequately explained the variation in species richness. The variations are best explained in terms of dispersal corridors along the Gouritz and Gamtoos River systems which connect the coastal forests with the inland mountains. The distribution patterns of four species groups in relation to the geomorphological history of the two river systems provide relative dates for the expansion and contraction of temperate forest, subtropical forest and subtropical transitional thicket in the southern Cape.

    Little is known about the nature of patients presenting to emergency departments (EDs) in South Africa. This study aimed to provide evidence on ED usage in Cape Town by studying patients at four community health centre (CHC) EDs, with details of the severity of their presentation and their disposal. A total of 16,392 patients presented in this 8-week prospective observational study, and 15,681 were included in the descriptive data analysis. One-quarter were children. There were clear and predictable peaks in attendance after 1600 hr and at weekends, with a steady stream of patients presenting overnight. Case severity was evenly distributed between emergency, urgent and routine care. Nearly 10% of patients were referred on to a higher level of care. The data from this study present a model for staffing and resource allocation. It has implications for the provision of emergency care in CHC EDs.

    In Colombia cape gooseberry is often grown on salt affected soils. The present study evaluated the effect of increasing NaCl concentrations on imbibition and percentage of germination of ‘Colombia’ ecotype cape gooseberry seeds. Under controlled laboratory conditions (25/20°C day/night temperature, 80% relative humidity, and a 12 hour photoperiod, the seeds were subjected to 0, 30, 60, 90 and 120 mM NaCl concentrations (corresponding to respective electrical conductivity levels of 0.8, 3.0, 6.0, 9.0, and 12.2 dS m-1, during an evaluation period of 299 hours. A significantly lower imbibition level, expressed as 35% of the fresh weight accumulated by the control seeds, was observed in the 120 mM NaCl treatment. At the end of the experiment, respective germination percentages of 97.6% and 96.4% were recorded in the salt-free seeds and in those exposed to 30 mM NaCl. In contrast, only 62.5% of those seeds treated with 120 mM NaCl germinated. Root malformations such as lack of elongation were observed in the highest NaCl concentration treatment. Regarding its germination process, cape gooseberry can be classified as moderately tolerant to sodium. In effect, after 299 h of treatment, there was no statistical difference in imbibition level or percentage of germination between the 0, 30 and 60 mM NaCl treatments.

    Full Text Available Abstract Background Despite high levels of substance use disorders in Cape Town, substance abuse treatment utilization is low among people from disadvantaged communities in Cape Town, South Africa. To improve substance abuse treatment utilization, it is important to identify any potential barriers to treatment initiation so that interventions to reduce these barriers can be implemented. To date, substance abuse research has not examined the factors associated with substance abuse treatment utilization within developing countries. Using the Behavioural Model of Health Services Utilization as an analytic framework, this study aimed to redress this gap by examining whether access to substance abuse treatment is equitable and the profile of variables associated with treatment utilization for people from poor communities in Cape Town, South Africa. Methods This study used a case-control design to compare 434 individuals with substance use disorders from disadvantaged communities who had accessed treatment with 555 controls who had not accessed treatment on a range of predisposing, treatment need and enabling/restricting variables thought to be associated with treatment utilization. A hierarchical logistic regression was conducted to assess the unique contribution that the need for treatment, predisposing and enabling/restricting variable blocks made on substance abuse treatment utilization. Results Findings revealed that non-need enabling/restricting variables accounted for almost equal proportions of the variance in service utilization as the need for treatment variables. These enabling/restricting variables also attenuated the influence of the treatment need and predisposing variables domains on chances of treatment utilization. Several enabling/restricting variables emerged as powerful partial predictors of utilization including competing financial priorities, geographic access barriers and awareness of treatment services.

    Full Text Available Abstract Background While the importance of promoting equity to achieve health is now recognised, the health gap continues to increase globally between and within countries. The description that follows looks at how the Cape Town Equity Gauge initiative, part of the Global Equity Gauge Alliance (GEGA is endeavouring to tackle this problem. We give an overview of the first phase of our research in which we did an initial assessment of health status and the socio-economic determinants of health across the subdistrict health structures of Cape Town. We then describe two projects from the second phase of our research in which we move from research to action. The first project, the Equity Tools for Managers Project, engages with health managers to develop two tools to address inequity: an Equity Measurement Tool which quantifies inequity in health service provision in financial terms, and a Equity Resource Allocation Tool which advocates for and guides action to rectify inequity in health service provision. The second project, the Water and Sanitation Project, engages with community structures and other sectors to address the problem of diarrhoea in one of the poorest areas in Cape Town through the establishment of a community forum and a pilot study into the acceptability of dry sanitation toilets. Methods A participatory approach was adopted. Both quantitative and qualitative methods were used. The first phase, the collection of measurements across the health subdistricts of Cape Town, used quantitative secondary data to demonstrate the inequities. In the Equity Tools for Managers Project further quantitative work was done, supplemented by qualitative policy analysis to study the constraints to implementing equity. The Water and Sanitation Project was primarily qualitative, using in-depth interviews and focus group discussions. These were used to gain an understanding of the impact of the inequities, in this instance, inadequate sanitation

    Africa's southern Cape is a key region for the evolution of our species, with early symbolic systems, marine faunal exploitation, and episodic production of microlithic stone tools taken as evidence for the appearance of distinctively complex human behavior. However, the temporally discontinuous nature of this evidence precludes ready assumptions of intrinsic adaptive benefit, and has encouraged diverse explanations for the occurrence of these behaviors, in terms of regional demographic, social and ecological conditions. Here, we present a new high-resolution multi-proxy record of environmental change that indicates that faunal exploitation patterns and lithic technologies track climatic variation across the last 22,300 years in the southern Cape. Conditions during the Last Glacial Maximum and deglaciation were humid, and zooarchaeological data indicate high foraging returns. By contrast, the Holocene is characterized by much drier conditions and a degraded resource base. Critically, we demonstrate that systems for technological delivery - or provisioning - were responsive to changing humidity and environmental productivity. However, in contrast to prevailing models, bladelet-rich microlithic technologies were deployed under conditions of high foraging returns and abandoned in response to increased aridity and less productive subsistence environments. This suggests that posited links between microlithic technologies and subsistence risk are not universal, and the behavioral sophistication of human populations is reflected in their adaptive flexibility rather than in the use of specific technological systems.

    2018-04-01

    The incidence of haematological malignancies in Africa's rapidly urbanising populations is insufficiently explored. Reliable population-based cancer statistics, however, continues to be a scarce resource in Africa and tends to be urban biased with limited rural coverage. In addition, many haematological malignancies are regarded as rare cancers, a sub-group that often affects the young disproportionately and require advanced diagnostic services and facilities able to deliver costly sophisticated treatments. This study provides a first attempt to estimate the incidence of haematological malignancies among the Eastern Cape Province population of South Africa. Multiple public- and private sector data archives and resources were utilised to optimise the identification of incident cases, including clinical records; bone marrow; cytology; histology; flow cytometry and cytogenetic records. Crude incidence, age-and gender-standardised rates are presented and comparison made with existing national data and select data from other economically developed countries and global institutions. A total of 3603 incident cases were identified between 2004 and 2013. Mature lymphoid malignancies accounted for approximately 60% (n = 2153), myeloma/plasma cell neoplasms 13% (n = 465), acute leukaemia 17% (n = 596), chronic myeloid leukaemia 4% (n = 155) and other myeloproliferative neoplasms 6% (n = 234) when stratified according to conventional groups. Most subtypes increase with age, with male excess. Haematological malignancies in the Eastern Cape Province show disparities in gender and pathology-specific incidence patterns. The present study suggest that haematological malignancies are not uncommon in this region and the incidence rate of at least one rare subtype, APL, is comparable with some European populations.

    2016-01-01

    This study examined the psychometric properties of the Child Adjustment and Parent Efficacy Scale-Developmental Disability (CAPES-DD), a brief inventory for assessing emotional and behavioral problems of children with developmental disabilities aged 2- to 16-years, as well as caregivers' self-efficacy in managing these problems. A sample of 636 parents participated in the study. Children's ages ranged from 2 to 15. Exploratory and confirmatory factor analyses supported a 21-item, three-factor model of CAPES-DD child adjustment with 13 items describing behavioral (10 items) and emotional (3 items) problems and 8 items describing prosocial behavior. Three additional items were included due to their clinical usefulness and contributed to a Total Problem Score. Factor analyses also supported a 16-item, one factor model of CAPES-DD self-efficacy. Psychometric evaluation of the CAPES-DD revealed scales had satisfactory to very good internal consistency, as well as very good convergent and predictive validity. The instrument is to be in the public domain and free for practitioners and researchers to use. Potential uses of the measure and implications for future validation studies are discussed.

This information was related with marine environmental predictors (species distribution models, existent areas of conservation concern for seabirds (i.e. marine Important Bird Areas; marine IBAs and threats to the marine environment in the West African areas heavily used by the shearwaters. There was an apparent inter-annual consistency on the spatial, foraging and trophic ecology of Cape Verde shearwater, but a strong alteration on the foraging strategies of adult breeders among breeding phases (i.e. from incubation to chick-rearing. During incubation, birds mostly targeted a discrete region off West Africa, known by its enhanced productivity profile and thus also highly exploited by international industrial fishery fleets. When chick-rearing, adults exploited the comparatively less productive tropical environment within the islands of Cape Verde, at relatively close distance from their breeding colony. The species enlarged its trophic niche and increased the trophic level of their prey from incubation to chick-rearing, likely to provision their chicks with a more diversified and better quality diet. There was a high overlap between the Cape Verde shearwaters foraging areas with those of European shearwater species that overwinter in this area and known areas of megafauna bycatch off West Africa, but very little overlap with existing Marine Important Bird

    The oil barge North Cape ran aground on Moonstone Beach in Rhode Island on January 19, 1996, spilling 828 000 gallons (US) of a combination of diesel and home heating oils. Samples of winter flounder embryos were collected from salt ponds in the area of the spill using an epibenthic sled. An examination of the field-sampled embryos based on gross morphology, levels of moribund embryos, mitotic index, and chromosomal anomalies found that a significant number exhibited high levels of one or more of these conditions when compared with flounder embryos raised under laboratory-controlled conditions. No chorion damage was noted in embryos collected from the field nor were there any significant findings of lordosis or scoliosis. The cumulative impact on winter flounder embryos of North Cape oil exposure was an estimated 51% reduction in the number of embryos surviving to the larval stage. (author)

    The effects of air drying temperature on dietary fibre, texture and microstructure of the Cape gooseberry fruits during convective dehydration in the range of 50-90 ºC were investigated. The ratio of insoluble dietary fibre to soluble dietary fibre was higher than 7:1 for all dehydrated samples. At 50 ºC tissue structure damage was evidenced leading to the maximum water holding capacity (47.4 ± 2.8 g retained water/100 g water) and the lowest rehydration ratio (1.15 ± 0.06 g absorbed water/g d.m.). Texture analysis showed effects of drying temperatures on TPA parameters. Changes in microstructure tissue were also observed at the studied drying temperatures. Hot air drying technology leads not only to fruit preservation but also increases and adds value to Cape gooseberry, an asset to develop new functional products.

    The U.S. Air Force (USAF) has tasked the Pacific Northwest Laboratory (PNL) in support of the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP), to identify, evaluate, and assist in acquiring all cost-effective energy projects at Cape Canaveral Air Force Station (AFS). Projects considered can be either in the form of energy management or energy conservation. The overall efforts of this task are based on a model program PNL is designing to support energy-use decisions in the federal sector. This report provides the results of the fossil fuel and electric energy resource opportunity (ERO) assessments performed by PNL at Cape Canaveral AFS, which is located approximately 10 miles north of Cocoa Beach, Florida. It is a companion report to Volume 1: Executive Summary and Volume 2: Baseline Detail. The results of the analyses of EROs are presented in 11 common energy end-use categories (e.g., boilers and furnaces, service hot water, and building lighting). A narrative description of each ERO is provided, including information on the installed cost, energy and dollar savings, impacts on operations and maintenance (O&M), and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. Descriptions of the evaluation methodologies and technical and cost assumptions are also provided for each ERO. Summary tables present the cost- effectiveness of energy end-use equipment before and after the implementation of each ERO and present the results of the life-cycle cost (LCC) analysis, indicating the net present value (NPV) and savings-to-investment ratio (SIR) of each ERO.

    Hepatitis B virus (HBV) diversity has not been previously studied in Cape Verde. The archipelago was discovered in 1460 by Portuguese explorers, who brought African slaves to colonise the islands. In this study, we investigated the HBV characteristics from 183 HBsAg-positive Cape Verdean individuals. Phylogenetic analysis of the pre-S/S region and the full-length genomes revealed 54 isolates with HBV/A1 (57%), 21 with HBV/A2 (22%), 19 with HBV/E (20%), and one with HBV/D (1%). HBV genotypes and subgenotypes were unequally distributed through the islands. In São Vicente, the main northern island, most isolates (84%) belonged to the African-originated HBV/A1, with the remaining isolates belonging to HBV/A2, which is prevalent in Europe. Interestingly, the HBV/A1 isolates from São Vicente were closely related to Brazilian sequences into the Asian-American clade, which suggests the dissemination of common African ancestors through slave trade. In contrast, in Santiago and nearby southern islands, where a recent influx from different populations circulates, a higher diversity of HBV was observed: HBV/A1 (40%); HBV/E (32%); HBV/A2 (28%); and HBV/D (1%). HBV/E is a recent genotype disseminated in Africa that was absent in the era of the slave trade. African and European human flows at different times of the history may explain the HBV diversity in Cape Verde. The possible origin and specifics of each HBV genotype circulating in Cape Verde are discussed.

    Full Text Available In this article, the researchers examine the direct impact of Information Systems Usage to Productivity at Cape Town Tourism. Data for the full sample of individuals who use information systems was analysed. The results clearly demonstrate that information systems has a positive impact on productivity. This is compromised however when there is a lack of training and poor systems performance. The study determined that in order to obtain the best out of the system, end users need to be consulted before implementation of any new system. System performance was also found out to be problematic as faced by employees of Cape Town Tourism when using their information systems.

    IntroductionThe U.S. Geological Survey (USGS), in support of the Massachusetts Estuaries Project (MEP), delineated groundwater-contributing areas to various hydrologic receptors including ponds, streams, and coastal water bodies throughout southeastern Massachusetts, including portions of the Plymouth-Carver aquifer system and all of Cape Cod. These contributing areas were delineated over a 6-year period from 2003 through 2008 by using previously published regional USGS groundwater-flow models for the Plymouth-Carver region (Masterson and others, 2009), the Sagamore (western) and Monomoy (eastern) flow lenses of Cape Cod (Walter and Whealan, 2005), and lower Cape Cod (Masterson, 2004). The original USGS groundwater-contributing areas were subsequently revised in some locations by the MEP to remove modeling artifacts or to make the contributing areas more consistent with site-specific hydrologic conditions without further USGS review. This report describes the process used to create the USGS groundwater-contributing areas and provides these model results in their original format in a single, publicly accessible publication.

    1986-03-29

    Blood lead levels were assessed in 293 children aged between 4 and 6 years attending preschool centers in metropolitan Cape Town in order to establish the degree of lead absorption. Anthropometric data, blood count, zinc protoporphyrin and blood lead level were obtained for each child. A questionnaire was used to determine socio-economic status, dietary habits and history of pica. Thirteen children, or 4,4% of those sampled, had blood levels of greater than or equal to 30 micrograms/dl. The majority of these children lived in close proximity to one another in a socially deprived inner urban environment. Environmental sampling for lead was carried out in the homes of children with the highest blood levels as well as in the homes of a matched control group with low levels living in the same area. The only difference was a significantly higher incidence of pica in the children with high levels.

    Full Text Available Article is dedicated to landing to Pikshuiy cape in April – May 1942. The article is described the preparation for it, stated problems, forces and facilities, and also motion of debarkation, the influence of severe weather conditions on the results of landing operation especially in detail is examined. The authors note that the tragedy played at Cape Piksaev was made possible due to the lack of attention of the command of the fleet to the weather, as an important element of the theatre, and the rear of miscalculations in the preparation of units, advancing from the occupied bridgehead on the land direction, to act in complex meteorological conditions. In the preparation of the landing was a violation of the requirements of a number of guidance documents.

  20. Redefining ecological ethics: science, policy, and philosophy at Cape Horn.

    Science.gov (United States)

    Frodeman, Robert

    2008-12-01

    In the twentieth century, philosophy (especially within the United States) embraced the notion of disciplinary expertise: philosophical research consists of working with and writing for other philosophers. Projects that involve non-philosophers earn the deprecating title of "applied" philosophy. The University of North Texas (UNT) doctoral program in philosophy exemplifies the possibility of a new model for philosophy, where graduate students are trained in academic philosophy and in how to work with scientists, engineers, and policy makers. This "field" (rather than "applied") approach emphasizes the inter- and transdisciplinary nature of the philosophical enterprise where theory and practice dialectically inform one another. UNT's field station in philosophy at Cape Horn, Patagonia, Chile is one site for developing this ongoing experiment in the theory and practice of interdisciplinary philosophic research and education.
