In this paper, a mathematical model is presented by which the cutting forces in gear form milling process are predicted using the mechanistic approach. To use this approach, a detailed description of the chip geometry is needed. Eccentricity and run-out tool errors are considered, which is of great importance as the chip thickness will by these errors vary for the subsequent cuts. The chip geometr
BACKGROUND: Associations between cadmium (Cd) and kidney function have been reported even at low levels of exposure in the general population. Recently, the causality of these associations has been questioned. OBJECTIVES: We examined associations between urinary Cd (U-Cd; a biomarker of exposure) and urinary proteins that are used as biomarkers of kidney effects, based on repeated short-term sampl
Migratory birds use multiple compass systems for orientation, including a magnetic, star and sun/polarized light compass. To keep these compasses in register, birds have to regularly update them with respect to a common reference. However, cue-conflict studies have revealed contradictory results on the compass hierarchy, favoring either celestial or magnetic compass cues as the primary calibration
Abstract in UndeterminedAccessibility to adequate health services is a basic human right. Israeli road blocks and checkpoints inhibit access to health care for the Palestinian population. While other studies have dealt with the impact of the barriers, few are based on actual measurements of transport times between locations. Geographical information systems (GIS) and network analysis were used to
Popular Abstract in Swedish Skolämnet livskunskap har vuxit fram i svenska skolor under det senaste decenniet, ofta utifrån en ambition att främja hälsa och att konkretisera skolans värdegrundsarbete. Avhandlingen belyser hur livskunskap växer fram och definieras som ett skolämne i nationella och kommunal dokument, och organiseras i lokal skolpraktik. Studien, som har en kombinerad barndomssocioloThe aim of this thesis is to understand and cast light over how the school subject Life Competence Education (Sw. Livskunskap) is developing in the Swedish school context. In focus of the study is how this school subject is defined and organized by actors (i.e. politicians, national governmental institutes, local governmental authorities, teachers and children in compulsory schools) in the differe
Background: Esophagus cancer (EC) is among the five most common cancers in both sexes in Iran, with an incidence rate well above world average. Social rank (SR) of individuals and regions are well-known independent predictors of EC incidence. The aim of current study was to assess gender and social disparities in EC incidence across Iran's provinces through 2003-2009. Materials and Methods: Data o
A complete reliability study of the DC and RF characteristics for InGaAs nMOSFETs with aluminium oxide/ hafnium oxide dielectric is presented. The main stress variation at high frequencies is related to a threshold voltage shift, whereas no decrease is found in the maximum of the cut-off frequency and RF-transconductance. Constant gate stress leads to a charge build up causing a threshold voltage
We show that coherent anti-Stokes Raman lineshapes do not follow known spectral profiles if the time asymmetry of realistic laser pulses is taken into account. Examples are given for nanosecond and picosecond laser pulses commonly employed in frequency-resolved coherent anti-Stokes Raman scattering. More remarkably, the analysis suggests an effect of line narrowing in comparison to the customary a
A multiscale modeling protocol was sketched for the trihexyltetradecylphosphonium chloride ([P-6,P-6,P-6,P-14]Cl) ionic liquid (IL). The optimized molecular geometries of an isolated [P-6,P-6,P-6,P-14] cation and a tightly bound [P-6,P-6,P-6,P-14]Cl ion pair structure were obtained from quantum chemistry ab initio calculations. A cost-effective united-atom model was proposed for the [P-6,P-6,P-6,P
With an increasing demand on load flexibility in power supply networks, advanced control systems for plants with carbon capture units gain in significance. Minimizing the energy demand for carbon dioxide removal under these circumstances is a major task of such a control strategy. In this work a dynamic model in Modelica of a chemical absorption process run with an aqueous monoethanolamine (MEA) i
The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. It has recently been suggested that the upward trend in net primary production (NPP) seen during the 1980's and 90's has been replaced by a negative trend since 2000 induced by severe droughts mainly on the southern hemisphere. Here we compare results from an individual-based glo
The Sn-124(Cl-37, 6n gamma) fusion-evaporation reaction at a bombarding energy of 180 MeV has been used to significantly extend the excitation level scheme of Ho-155(67)88. The collective rotational behavior of this nucleus breaks down above spin I similar to 30 and a fully aligned noncollective (band terminating) state has been identified at I-pi = 79/2(-). Comparison with cranked Nilsson-Strutin
PURPOSE. The aims of this study were to use transscleral optical spectroscopy to analyze normal and tumor-infiltrated areas of enucleated human eyes, and to characterize the spectral properties of uveal melanomas in relation to various morphological features. METHODS. Nine consecutive eyes enucleated for uveal melanoma were examined by transscleral spectroscopy, using a fiber-optic probe that exer
Gestational enterovirus (EV) infections have been associated with an increased risk for type 1 diabetes in the offspring. We therefore analyzed non-diabetic mothers for EV exposure in early pregnancy in relation to type 1 diabetes HLA-DQ risk genotypes and seroconversion to islet autoantibodies during pregnancy. Non-diabetic mothers who had islet autoantibodies (n=365) against glutamic acid decarb
