Popular Abstract in Swedish Nanoteknik och nanotrådar omnämns ofta media idag, men vad är egentligen en nanotråd, och vad kan den användas till? Dagens datorer, lysdioder och solceller är till stor del beroende av halvledare. En halvledare är ett kristallint material där man enkelt kan ändra ledningsförmågan. Man kan dels bestämma ledningsförmågan när materialet tillverkas genom att tillföra ytterThis thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. The first part of the thesis describes the development of Hall effect measurements, an entirely new characterization tool for nanowires. It is shown that Hall effect me

Abstract in UndeterminedWith the help of the Argentine writer Borges, I will illustrate the absurdity of assuming that science may either grasp reality fully or convey it through abstractions. My departing point is that every methodological perspective has something to contribute to our attempts to elucidate anomalous experiences, and that the extremes of “realness” or abstraction lead to fallacie

A group of 51 cases with anorexia nervosa (including a total population of cases from one birth cohort) was compared with a sex-, age- and school-matched group of 51 cases on various measures of family demography and interactions. There was no support for the notion of a "typical anorexia nervosa family." However, there were more major problems in the anorexia group and there was also a higher pre

Shape characteristics of rising-falling accentual F0 peaks of Stockholm Swedish Accent I words in narrow focus are studied in a corpus of 287 read sentences. The corpus includes statements and three types of polar questions. Results reveal a clear effect of sentence mode on the shape of the accentual rises: Statements are predominantly characterized by convex rises, questions by concave rises.

Popular AbstractI takt med att svenska företag har ökat sina utlandssatsningar med bland annat direktinvesteringar på utländska marknader har också efterfrågan av internationell rörlighet bland den svenska kvalificerade arbetskraften ökat. En del av detta behov rör tidsbegränsade utlandsposteringar av svensk arbetskraft på så kallade ’expats-kontrakt’. Ofta utgår samhällsdebatten från en uppfattniAs Swedish companies have increased their commitments abroad, the demand for internationally mobile skilled Swedish labour has increased. Some of this demand concerns temporary positions on so called ’expats-contracts’. Often the discussion on this issue originates from a discourse that claims this type of labour force to be unanimously positive towards moving abroad to work. International tempora

Soil salinity and solute movements through the soil are considered the most important challenge facing agriculture in Arid and Semiarid regions (e.g., Egypt). The objective of the present study is to investigate soil salinity problems and different strategies to control or reduce them, and increase crop yield at a national project called the El-Salam Canal service area in north-eastern Egypt.
