Background: Exposure to ambient air particulate matter (PM) has been linked to decline in pulmonary function and cardiovascular events possibly through inflammation. Little is known about individual exposure to ultrafine particles (UFP) inside and outside modern homes and associated health-related effects. Methods: Associations between vascular and lung function, inflammation markers and exposure

Thermal manikins are useful tools to study the clothing comfort and environmental ergonomics. The simulation of sweating can be achieved by putting a highly wicking stretchable knit fabric “skin” on top of the manikin. However, the addition of such a fabric skin makes it is difficult to accurately measure the skin surface temperature. Moreover, it takes considerable amount of time to measure the f

This thesis concerns the role of disability and assistive devices in everyday life among persons with, for instance, impairments related to mobility (e.g. wheelchair users) and bodily shape and configuration (e.g. dysmelia). Assistive devices are seen as both includators (assisting participation and emancipation) and excludators (limiting participation, restraining empowerment, and stigmatizing).

In the title compound, [Re(3)(mu-H)(3)(C(25)H(22)P(2))(CO)(10)]center dot CH(2)Cl(2), the three Re atoms form a triangle bearing ten terminal carbonyl groups and three edge-bridging hydrides. The bis(diphenylphosphanyl) methane ligand bridges two Re atoms. Neglecting the Re-Re interactions, each Re atom is in a slightly distorted octahedral coordination environment. The dichloromethane solvent mol

The fatigue crack propagation rate is influenced by various mechanisms at the very vicinity of the crack tip, e.g., local plasticity and/or creep, microcracking, crack branching, and crack closure induced by plasticity and roughness. To study these mechanisms and their influence on crack propagation rate during different loadings, in situ scanning electron microscope studies have been performed. T

Every year, approximately 1 million new colorectal cancer (CRC) cases are diagnosed and about half a million people worldwide die due to this cancer. Known differences in CRC incidence rates are mainly attributed to differences in diet and other environmental factors represented, among others, by nutrition-related complex diseases (e.g. obesity and diabetes mellitus type II). Within the last years

BACKGROUND: Exposure to perfluorooctane sulfonate (PFOS) may potentially disturb fetal Leydig cell hormone production and male genital development. OBJECTIVES: We aimed to study the associations between levels of amniotic fluid PFOS, fetal steroid hormone, and insulin-like factor 3 (INSL3) and the prevalence of cryptorchidism and hypospadias. METHODS: Using the Danish National Patient Registry, we

Den svenska supply chain-panelen har under 2013 etablerats av forskare från Institutionen för teknisk ekonomi och logistik vid Lunds universitet LTH. Paneldeltagarna svarar på fyra enkla enkäter, kring olika supply chain-frågor. Den andra enkäten, som redovisas här, fokuserade hur företag arbetar med Sales & Operations Planning (S&OP). Analysen bygger på svar från 63 panelmedlemmar från o

Donor-reactive CD4(+) memory T cells threaten the survival of transplanted organs. In this study, we used anti-CD44 monoclonal antibody (mAb) to inhibit adoptively transferred B6-reactive CD4(+) memory T cells (BALB/c origin) and to induce tolerance of B6 hearts in nude mice. The median survival time (MST) of the grafts was 6 days in the isotype group, and more than 100 days in the group treated w

A new simulation method for nonuniform polymer solutions between planar surfaces at full chemical equilibrium is described. The technique uses a grid of points in a two-dimensional thermodynamic space, labeled by surface area and surface separations. Free energy differences between these points are determined via Bennett's optimized rates method in the canonical ensemble. Subsequently, loci of con

A critical factor in simultaneous saccharification and fermentation (SSF) is the selection of process temperature, which needs to be a compromise between the optimal temperature for enzymatic hydrolysis and that for fermentation. In the present work, isothermal and nonisothermal SSF was experimentally studied using pretreated spruce and arundo materials at a loading of 10% water insoluble solids,

Global climate change stands out from most environmental problems because it will span generations and force us to think in new ways about intergenerational fairness. It involves the delicate problem of complex coordination between countries on a truly global scale. As long as fossil fuels are too cheap, climate change policy will engage all major economies. The costs are high enough to make effic

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guid

We introduce a wide subclass F(X, w) of quasi-plurisubharmonic functions in a compact Kahler manifold, on which the complex Monge-Ampere operator is well defined and the convergence theorem is valid. We also prove that F(X, w) is a convex cone and includes all quasi-plurisubharmonic functions that are in the Cegrell class.

Background: Patient-reported outcome (PRO) instruments are used in all medical disciplines to evaluate patients with different diseases and also to follow results after treatments such as surgery. Currently there is no generally accepted and fully validated PRO instrument for the foot and ankle. Aims: To translate the New Zealand Ankle Questionnaire into a Swedish version, [the Self-Reported Foot
