It is recognized that cooling methods incorporating micro-channel heat sinks with high capacities of heat removal are necessary for cooling of electronic devices. In this paper, based on a water-cooled smooth micro-channel heat sink, a series of rectangular-shaped flow obstructions are designed into a heat sink, and then the corresponding laminar flow and heat transfer have been analyzed numerical

Caloplaca herbidella (Hue) H. Magn. and C. furfuracea H. Magn. are two isidiate, epiphytic species in the large genus Caloplaca. Caloplaca herbidella in a strict sense is normally grey and fertile with thick, somewhat coralloid isidia, but orange, sterile forms with thin isidia also occur. Caloplaca furfuracea is superficially similar morphologically to C. herbidella s. str. but has thinner, more

We present a study of InAs/InSb heterostructured nanowires by X-ray photoemission spectroscopy (XPS), scanning tunneling microscopy (STM), and in-vacuum electrical measurements. Starting with pristine nanowires covered only by the native oxide formed through exposure to ambient air, we investigate the effect of atomic hydrogen cleaning on the surface chemistry and electrical performance. We find t

Popular Abstract in Swedish Biologiska organismer har en fantastisk förmåga att anpassa sig till alla möjliga miljöer. Människans aktiviteter på jorden har skapat många nya habitat för olika typer av organismer; t ex kan vissa organismer växa på sten och vertikala klippor och när människor bygger hus så kan dessa organismer flytta över till väggar och tak som blir nya biotoper att leva på. Några aBiological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on. Some of these expa

Context: This review focuses on the prevention and management of complications following radical cystectomy (RC) for bladder cancer (BCa). Objective: We review the current literature and perform an analysis of the frequency, treatment, and prevention of complications related to RC for BCa. Evidence acquisition: A Medline search was conducted to identify original articles, reviews, and editorials a

The Tokyo Medical University Hospital in Japan and the Lund University hospital in Sweden have recently initiated a research program with the objective to impact on patient treatment by clinical disease stage characterization (phenotyping), utilizing proteomics sequencing platforms. By sharing clinical experiences, patient treatment principles, and biobank strategies, our respective clinical teams

A key component in successfully managing software products is to properly, and in a timely manner, identify and secure competitive advantage by innovation via feature differentiation. Although open source software (OSS) is not a new idea, several product development companies that operate in a market-driven context have started to use open source solutions as core software components in their prod

Popular Abstract in Swedish Hur lurar mördarbakterier våra celler? Neutrofiler och fagocytos räddar liv Utan vårt immunförsvar så skulle vi snabbt dö i infektioner från mikroorganismer. Det består ett komplicerat system av celler och molekyler som tillsammans kan klara av att stå emot attacker från bakterier, virus, svampar eller parasiter. Cellerna i immunförsvaret utgörs av vita blodkroppar ochNeutrophils are our most numerous and deadly white blood cells and without them we would succumb quickly to infections by pathogens. The main mechanism that the neutrophils employ for our protection is phagocytosis, where they eat and enclose their target inside a membrane-bound organelle, the phagosome. Neutrophil phagosomes are highly dynamic entities, and a large amount of antimicrobial substan

The formation of lumps is a common problem during powder reconstitution in food industry. If more knowledge regarding the phenomena controlling the process could be obtained, the process of industrial powder recombination could be optimized. This demands investigation of the process at three different levels: the scale of individual powder particles, the scale of powder beds, and the scale of indu

Popular AbstractI denna avhandling studeras förhållandet mellan människa och djur, i synnerhet människans relation till lantbrukets djur. Med teoretiska perspektiv från socialkonstruktivism och existentiell fenomenologi behandlas frågor om hur djur och nötkreatur (som utgör en fallstudie) framträder i diskurser och hur de ingår i bönders livsvärldar. Utifrån debatterna om belgisk blå, BSE (galna kThis dissertation is concerned with the relationship between humans and animals. In particular, it explores human relations to farm animals, and especially cattle. The empirical and theoretical work is concerned with how animals appear in discourses and how they form part of human life worlds. Three debates about recent animal-related issues are examined: the introduction of the cattle breed Belg
