Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w

Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.

The reactions between trans-[Au(CN) 2 X 2 ] - (X = Cl or Br) and Me 2 S have been studied by conventional and high-pressure stopped-flow spectrophotometry in acidic aqueous solution containing 10% (w/w) methanol. The overall stoichiometry Au III ∶Me 2 S is 1∶(1.0 ± 0.1) in agreement with the reaction: trans-[Au(CN) 2 X 2 ] - + Me 2 S + H 2 O → [Au(CN) 2 ] - + Me 2 SO + 2H + + 2X - . Initial rapid

This article presents and argues for a collaborative model for disaster risk management in the Southern African Development Community (SADC). The research employed a qualitative study through a literature review and empirical research through focus group interviews to realize its objectives. As a key theory of multinational collaboration, neoliberal institutionalism—a subset of the international r

In this paper a simple analytical method is introduced for calculating the overall thermal conductivity of a twin pipe in district heating network. The method is developed based on calculating the conductive and convective heat transfer around the casing pipe in different perimetral sections. Temperature inside the supply and return pipes and also over the heating pipe is measured on different poi

Background: Angioedema is a rare and serious adverse drug reaction (ADR) to angiotensin-converting enzyme (ACE) inhibitor treatment. Dry cough is a common side effect of ACE inhibitors and has been identified as a possible risk factor for angioedema. Objective: We compared characteristics between patients with ACE inhibitor–induced angioedema and cough with the aim of identifying risk factors that

Sepsis is a systemic immune response responsible for considerable morbidity and mortality. Molecular modeling of host-pathogen interactions in the disease state represents a promising strategy to define molecular events of importance for the transition from superficial to invasive infectious diseases. Here we used the Gram-positive bacterium Streptococcus pyogenes as a model system to establish a

Energy-intensive processing industries (EPIs) produce iron and steel, aluminum, chemicals, cement, glass, and paper and pulp and are responsible for a large share of global greenhouse gas emissions. To meet 2050 emission targets, an accelerated transition towards deep decarbonization is required in these industries. Insights from sociotechnical and innovation systems perspectives are needed to bet

Antigenic diversity in pathogenic microbes can be a result of at least three different processes: diversifying selection by acquired immunity, host–pathogen coevolution and/or host specialization. Here, we investigate whether host specialization drives diversity at ospC (which encodes an immunodominant surface protein) in the tick-transmitted bacterium Borrelia afzelii. We determined prevalence an

The capacity of communities to reduce negative impacts of climate change on their lives and livelihoods is a function of socio-economic conditions, infrastructure, government accountability and institutional responsiveness and not the least social capital. Africa’s most densely populated region, the Lake Victoria basin (LVB), home to over 30 million people, is one example of a likely future climat

The ability to rapidly detect cell free circulating (cfc) DNA and other nanoparticulate disease biomarkers directly in blood is a major challenge for nanomedicine. We now show that AC Electrokinetic (ACE) microelectrode array devices can be used to rapidly isolate and detect cfc-DNA nanoparticulates directly from whole blood and other high conductance samples (plasma, serum etc.). The device shows

Projects often suffer from lack of logistics considerations in the early phases. Since logistics is not the main focus of the people involved in the project, logistics solutions become reactive rather than proactive. With the increasing global competition, forcing companies to shorten time-to-market for their projects and becoming more cost effective, it becomes increasingly important to manage pr
