Botswana has figured widely as the exceptional African growth success story and has been frequently cited in scholarship that supports the view that African and other less developed economies are capable of rapid economic growth as long as the internal institutional framework and development policies are right. A shortcoming of the literature on African economic performance to date is that it has
To meet the economic requirements of power output, the increased inlet temperature of modern gas turbines is above the melting point of the material. Therefore, high-efficient cooling technology is needed to protect the blades from the hot mainstream. In this study, film cooling was investigated in a simplified channel. A bulge located upstream of the film hole was numerically investigated by anal
The degenerative process in Alzheimer´s disease (AD) follows a temporal and topographic pattern of early and accentuated involvement of temporal limbic, parietal and posterior cingulate cortices. We have studied a pedigree with four generations suffering from early onset AD linked to a presenilin-1 gene mutation. This family now contains 7 AD cases, neuropathologically confirmed in four cases of t
Background: The landlocked mountain country of Nepal has an extreme topography and is one of the poorest and least developed countries in the world. Nepal has ratified and signed the Convention on the Rights of Persons with Disabilities (CRPD). To understand what is required to improve prosthetic provision and services for persons living with an amputation in low-income countries, it is of interes
A semistructured personal interview with 29 female carriers of hemophilia and 23 of their spouses was performed at a median of 3 1/2 years after the first chorionic villus sampling (CVS) and gene analysis. Carriers with a hemophilic father or brother, had high sense of coherence (SOC) scores, and thus would be expected to have good ability to handle the stress of prenatal diagnosis (PD). Prenatal
The computing grid is a distributed parallel processing system that share and choosing resources dynamically and provide need of user operation power, cost and quality .grid management resources does as a diagnostic and assigning resources scheduling and resource monitoring in grid . Scheduling process directs tasks to suitable resources. It must take place some how that load work distributed equa
Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the magnitude and geographic pattern of future fire impacts rests on our ability to model fire regimes, using either well-fou
A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (e or μ), or at least three isolated leptons, is presented. The analysis relies on the identification of b-jets and high missing transverse momentum to achieve good sensitivity. A data sample of proton-proton collisions at s=13 TeV recorded with the A
We present the use of capillary driven flow over patterned surfaces to achieve cheap and simple, but powerful separation of biologically relevant particle systems. The wide use of microfluidics is often hampered by the propensity for devices to clog due to the small channel sizes and the inability to access the interior of devices for cleaning. Often the devices can only be used for a limited dura
Background: The aim of this study was to investigate graft preservation, major bleeding, and reinfection rate using negative pressure wound therapy (NPWT) for perivascular surgical site infections (SSIs) in the groin after vascular surgery and factors associated with failure of treatment. Methods: Retrospective data were collected during 2004-2015. Failure of wound treatment was defined as a wound
BACKGROUND: Tumor-infiltrating lymphocytes (TILs) have a strong prognostic value in various forms of cancers. These data often refer to use of the pan-T cell marker CD3, or the cytotoxic T lymphocyte marker CD8α. However, T cells are a heterogeneous group of cells with a wide array of effector mechanisms ranging from immunosuppression to cytotoxicity. OBJECTIVE: In this study we have investigated
Kinetic models are among the tools that can be used for optimization of biocatalytic reactions as well as for facilitating process design and upscaling in order to improve productivity and economy of these processes. Mechanism pathways for multi-substrate multi-product enzyme-catalyzed reactions can become very complex and lead to kinetic models comprising several tens of terms. Hence the models c
Climate change (CC) is one of the major and most encompassing threats in the world today. While the facts and high-consensus predictions among natural scientists are increasingly well-known, the understanding of CC as a socio-ecological issue is much less clear and uncontroversial. This paper summarizes the available climate science expertise and then discusses the genesis of CC as a socio-ecologi
The mechanisms underlying longitudinal displacements of the arterial wall, that is, displacements of the wall layers along the artery, and the resulting intramural shear strain remain largely unknown. We have already found that these displacements undergo profound changes in response to catecholamines. Wall shear stress, closely related to wall shear rate, represents the viscous drag exerted on th
Objectives. To study possible nerve regeneration of a damaged auditory nerve by the use of stem cell transplantation. Methods. We transplanted HNPCs to the rat AN trunk by the internal auditory meatus (IAM). Furthermore, we studied if addition of BDNF affects survival and phenotypic differentiation of the grafted HNPCs. A bioactive nanofiber gel (PA gel), in selected groups mixed with BDNF, was ap
For pulse combustors of the Helmholtz type, a heat transfer of the order two to five times higher than expected has been reported. Experiments, where the temperature profile in the tail pipe of a pulse combustor has been measured, give Ilo indication why the heat transfer should be enhanced. The interaction between the oscillating velocity field and the oscillating temperature field might explain
This report presents the results from a study of 90 km/h rural roads, where the effects of narrow vs. wide lanes on deterioration, safety, winter maintenance etc have been studied. Empirical studies have been performed of lateral positioning and speed on 16 road objects that vary with regards to lane width (3.25m respectively 3.75m) and presence of guardrail (with or without), other parameters hav
The quinoline-3-carboxamides (Q compounds) are a family of small molecules that ameliorate various types of murine inflammatory autoimmune disease. One such compound has also demonstrated anti-tumor effects in murine tumor models. Several Q compounds have reached clinical trials and one compound, laquinimod, is currently in phase III clinical trial for relapsing-remitting multiple sclerosis. The Q
This study highlights school nurses' view of schoolchildren's health and their attitude to document it in the school health records. A strategic sample of 12 school nurses was interviewed. The interviews were semistructured and analysed with qualitative content analysis. The findings showed that the school nurses' viewed schoolchildren as physical healthy although they called attention to growing
