Responses of prey from habitats with different predator regimes: local adaptation and heritability

We aimed to assess whether prey organisms with limited large-scale dispersal abilities are locally adapted to prevailing predator regimes by studying how chemical cues from predatory fish affected the behavior of Gammarus pulex (Amphipoda) from ponds with and without fish. We also examined, in the laboratory, the F1 generation from each pond by incubating them with or without cues from predatory f

Bishop score and ultrasound assessment of the cervix for prediction of time to onset of labor and time to delivery in prolonged pregnancy.

Objectives To determine the ability of Bishop score and sonographic cervical length to predict time to spontaneous onset of labor and time to delivery in prolonged pregnancy. Methods Ninety-seven women underwent transvaginal ultrasound examination and palpation of the cervix at 291-296 days' gestation according to ultrasound fetometry at 12-20 weeks' gestation. Sonographic cervical length and Bis

Chronopharmacologic aspects of hexobarbital oxidation rate in rats

Circadian variations of hexobarbital oxidation rate in rat liver and the relationship to serum corticosterone levels were determined in 324 animals subjected to different lighting regimen and feeding schedules.--Rats maintained under standard light/dark conditions and with free access to food showed a significant circadian hexobarbital oxidase rhythmicity. Inversion of the light/dark cycle and tim

A meta-analysis of previous fracture and subsequent fracture risk

Previous fracture is a well-documented risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the relationship of this risk with age, sex, and bone mineral density (BMD). We studied 15259 men and 44902 women from 11 cohorts comprising EVOS/EPOS, OFELY, CaMos, Rochester, Sheffield, Rotterdam, Kuopio, DOES, Hiroshima, and two cohorts

Reconstitution of water channel function of an aquaporin overexpressed and purified from Pichia pastoris.

The aquaporin PM28A is one of the major integral proteins in spinach leaf plasma membranes. Phosphorylation/dephosphorylation of Ser274 at the C-terminus and of Ser115 in the first cytoplasmic loop has been shown to regulate the water channel activity of PM28A when expressed in Xenopus oocytes. To understand the mechanisms of the phosphorylation-mediated gating of the channel the structure of PM28

Fourier-transform infrared spectroscopy (FTIRS), a new method to infer past changes in tree-line position and TOC using lake sediment

This study tests the hypothesis that Fourier-transform infrared spectroscopy (FTIRS) of lake sediments can be used to infer past changes in tree-line position and total organic carbon (TOC) content of lake water. A training set of 100 lakes from northern Sweden spanning a broad altitudinal and TOC gradient from 0.7 to 14.9 mg/l was used to assess whether vegetation zones and TOC can be modelled fr

Structural fire behaviour - development trends

During the last two decades, a rapid progress has been made in the development of analytical methods for a fire engineering design of load bearing and separating structures and structural members. Consequently, more and more countries are now permitting a classification of structural members with respect to fire to be formulated analytically as an alternative to the internationally prevalent metho

A Predictive Real Time NOx Model for Conventional and Partially Premixed Diesel Combustion

A previously presented robust and fast diagnostic NOx model was modified into a predictive model. This was done by using simple yet physically based models for fuel injection, ignition delay, premixed heat release rate and diffusion combustion heat release rate. The model can be used both for traditional high-temperature combustion and for high-EGR, low-temperature combustion. It was possible

Increased mortality after fracture of the surgical neck of the humerus: a case-control study of 253 patients with a 12-year follow-up.

Background: Several studies have shown a higher mortality rate in patients with osteoporosis-related fractures of the hip and vertebrae. Method: In 1999, we did a long-term follow-up case-control mortality study of 253 patients, mean age 72 years, who had sustained a fracture of the surgical neck of the humerus in 1987. Results: We found a higher mortality in fracture patients giving at end point

Power Constrained Preemptive TAM Scheduling

We integrate scan-chain partitioning and preemptive test access mechanism (TAM) scheduling for core-based systems under power constraint. We also outline a flexible power conscious test wrapper to increase the flexibility in the scheduling process by (1) allowing several different bandwidths at cores and (2) controlling the cores test power consumption, which makes it possible to increase the test

Tingens och tankarnas landskap : försök i naturumgängets arkeologi med exempel ur Blekinges och Smålands förflutna

Popular Abstract in Swedish Avhandlingen ”Tingens och tankarnas landskap” söker arkeologiska metoder och teorier för ett humanistiskt närmande av människans tidiga naturumgänge. Med arkeologiskt menas här fokuseringen på de materiella spåren i landskapet, stora som små, naturdanade som människotillverkade. Tidsperspektivet är i huvudsak långtida. I avhandlingen har jag valt ett ekologiskt perspektThe thesis "Tingens och tankarnas landskap" is about the material traces of man and his activities in the past. The study investigates the possibility and methods of describing man’s interaction with nature. Man’s relationship to the physical surroundings is viewed from cultural and social perspectives, using the materials of long-term archaeology. The study also includes a contemporary dimension.

Thin graphite overlayers: Graphene and alkali metal intercalation

Using LEED and angle resolved photoemission for characterisation we have prepared graphite overlayers with down to monolayer thickness by heating SiC crystals and monitored alkali metal intercalation for the multilayer films. The valence band structure of the monolayer is similar to that calculated for graphene though downshifted by around 0.8 eV and with a small gap at the zone corner. The shift
