Class II antigens of the major histocompatibility complex (MHC) consist of two glycosylated, membrane-integrated polypeptide chains1. These cell surface-expressed molecules are involved in several immunobiological events involving cell-cell interactions2,3, most of which seem to require that genetically identical class II antigens, or other molecules controlled by the same region of the MHC, are e

We report on the synthesis of vertical InP nanowire arrays on (001) InP and Si substrates using template-assisted vapour–liquid–solid growth. A thick silicon oxide layer was first deposited on the substrates. The samples were then patterned by electron beam lithography and deep dry etching through the oxide layer down to the substrate surface. Gold seed particles were subsequently deposited in the
This article is based on research performed in Lund on the taxation of women in income tax. This series of two articles deals with the question whether the family or the individual would be the most suitable unit of taxation. This second article discusses other criteria including tradition, status quo, ability to pay, solidarity within families, the UN social development goals (gender equality),
Semiconductor nanowires are widely considered as promising candidates for next generations of electronics and optoelectronics. Gold seed particles have so far been recognized as the most important catalyst for growth of nanowires. Costs related to substrates, lithography processes and gold consumption most strongly influence the final cost of nanowire-based devices. An optimum gold deposition proc
Purpose: For primary health care (PHC), hypertension is the number one diagnosis for planned health care visits. The treatment of high blood pressure (BP) and its consequences constitutes a substantial economic burden. In spite of efficient antihypertensive medications, a low percentage of patients reach a well-controlled BP. The PERson-centredness in Hypertension management using Information Tech
The use of pesticides has caused pollution of surface and groundwater, soil and air across the world. Many pesticides cause health effects in humans. General populations are exposed to some degree and diet is reported to be a main source of exposure. It is important to study exposure and exposure-effect relationships in occupational groups and in general populations. For such studies, good methods
High-pressure homogenizers are often used in tomato juice production to fragment tomato cells, to increase viscosity. Compared to emulsification, little is known about the mechanism of cell breakup in general and of vegetable cell breakup in particular. The objective of this contribution is to extend the mechanistic understanding of vegetable cell breakup in homogenizers, using a research methodol
Reactivity controlled compression ignition (RCCI) engines suffer from low thermal efficiency at low loads due to the high hydrocarbon and carbon monoxide emissions. Correspondingly, a direct dual fuel stratification (DDFS) combustion mode is investigated by directly injecting methanol and diesel into cylinder. Multi-objective optimization and detailed comparison are first conducted for the two eng
