Insulation reduction of footwear: 1-day sweating test on a thermal foot model

The present paper is discussing some results of the bigger experiment that was conducted in order to study the effect of different sweat rates (3, 5 and 10 g/h) on footwear insulation. During the study series some tests with 8-hour sweating were carried out. A thermal foot model was used for testing. The model is divided into 8 zones and had 5 “sweat glands”. A thin sock was donned on foot model f

On the concept of concept in the context of autonomous agents

This paper deals with some fundamental questions regarding the concept of concept in the context of autonomous agents. The most basic of these is defining what it actually means for someone to have a concept. Rather than trying to state a number of conditions that should be satisfied in order to have the concept, it is concluded that having a concept is a matter of degree, which can be defined in

Phenomenological Studies on Supersymmetry and the Strong Force

In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. The augmented generator has then been used to study event properties of these models, mainly at the LHC. During these studies, th

Magnetic compass of migratory Savannah sparrows is calibrated by skylight polarizarion and sunrise and sunset

Migratory birds use compass systems derived from the geomagnetic field, the stars, the sun and polarized light patterns. We tested whether birds use a single underlying reference system for calibration of these compasses and, specifically, whether sunset and sunrise polarized light cues from the region of the sky near the horizon are used to calibrate the magnetic compass. We carried out orientati

Long-term outcome in term breech infants with low Apgar score--a population-based follow-up

OBJECTIVE: To investigate the relation between low Apgar score in breech infants and handicap in childhood. STUDY DESIGN: A case-control study. A questionnaire to mothers of 323 non-malformed, singleton infants delivered in breech presentation at term, 105 cases with Apgar score below 7 at 5 min and 218 controls. RESULTS: Four cases (4.6%) and one control (0.5%) had cerebral palsy. In infants with

The Effect of Having an Affected Parent or Sibling on Invasive and In Situ Skin Cancer Risk in Sweden

Studies suggest that skin cancer aggregates within families; however, the risk of skin cancer associated with having an affected sibling or parent by subtype, tumor site, and age at diagnosis has not been established. The 2006 update of the Swedish Family-Cancer Database was used to calculate standardized incidence ratios (SIRs), representing the ratio of cancer risk among individuals with affecte

Cross-Sectional and Serial Correlation in a Small-Sample Homogeneous Panel Data Unit Root Test

In this paper, response surface parameters are provided that can be used to obtain critical values for an augmentation of an existing homogeneous panel data unit root test. The augmentation is performed to account for serial correlation in the disturbances. As the existing panel data unit root test is robust against cross-sectional correlation, the augmented test is robust against both cross-secti

Purification, characterization, and expression of rat intestinal alkaline sphingomyelinase.

Intestinal alkaline sphingomyelinase (SMase) has physiological roles in the digestion of sphingomyelin (SM) and clinical implications in colonic carcinogenesis. In the present work, the enzyme from rat has been purified 1,589-fold with 11% recovery by elution of the intestine with bile salt, precipitation of the proteins by acetone, and several types of chromatographies. Its molecular mass was 58
