Blood transfusion is a clinically significant and crucial process, which saves millions of lives every year. However,shortage of donated blood and the risk of virus transmission through transfusible blood seriously affect theavailability of the blood. Hemoglobin (Hb), owing to its oxygen carrying capacity, has been studied as a startingmaterial for the development of artificial blood substitutes/H
Baker’s yeast, Saccharomyces cerevisiae, is a promising cell factory for the sustainable utilization of renewable resources for the formation of products with commercial value. Among these, poly-3-D-hydroxybutyrate (PHB) is an extensively studied biopolymer naturally accumulated in some bacteria and archaea species through the formation of carbon granules. Its bio-based origin, biodegradability an
The main purpose of this study was to compare two non-invasive optical spectroscopic techniques for assessing peripheral oxygenation saturation in healthy volunteers under specific provocations. The results suggest that the time-resolved technique provides more accurate and robust results.
This paper brings forward a service oriented perspective, based on practical experiences from designing information systems (IS) as services. Viewing IS as services are beneficial but still an unexplored approach in organizations. In this paper, we present an analysis of Enterprise Resource Planning (ERPs) systems through the perspective of Service Oriented Architecture (SOA). This paper contribut
The main purpose of this study was to investigate a novel non-invasive optical technique for rapid bedside detection of oxygen gas in the lungs of full-term newborn infants. The results suggest that the technique will be clinically useful as a diagnostic and monitoring tool for infants with lung disorders.
We study upscaling of gas high harmonic generation, to make efficient use of the ever increasing laser pulse powers. Loose focusing geometries optimizing phasematching are investigated and compared in HHG efficiency to shorter focusing arrangements.
Extrapolating nonlinear phenomena, such as filamentation, to new parameters as e.g. to higher pulse energy is often challenging. We here present a general scaling model for nonlinear light-matter interactions in gases and proof it experimentally.
The heat recovery system for ventilation is of major importance when low energy buildings are built. One alternative to the mechanical ventilation systems with heat recovery is to use a brine based run-around system that allows for heat recovery in for instance hybrid ventilated buildings. This type of heat recovery system has the potential to lower the need for electricity for the fans.

Arsenic is an established carcinogen and a risk factor for several non-malignant diseases. Mechanisms of arsenic toxicity may include interference with gene expression. The impact of arsenic exposure on gene expression was evaluated in women (n = 80) living in the Puna of the northern Argentinian Andes with varying concentrations (10–1251 μg/L) of arsenic in drinking water.

This article presents findings from a Computational Fluid Dynamics (CFD) study performed on the heat transfer characteristics of diesel and partially-premixed combustion (PPC) engines. The study is confined to the combustion bowl, where numerical simulations have been performed on a part of the engine cycle, namely the compression, combustion, and expansion phases. Three engine geometries were sim
In this work, we present a novel formulation for efficient estimation of group-sparse regression problems. By relaxing a covariance fitting criteria commonly used in array signal processing, we derive a generalization of the recent SPICE method for grouped variables. Such a formulation circumvents cumbersome model order estimation, while being inherently hyperparameter-free. We derive an implement
Exposure to inorganic arsenic (iAs) is a risk factor for cancer. Alterations in mitochondrial DNA copy number (mtDNAcn) and telomere length (TL) have been associated with cancer risk. Two Argentinean groups were studied: A) Puna area of Andes and B) Chaco. Arsenic exposure was assessed as the sum of arsenic metabolites (iAs, MMA, and DMA) in urine (U-As) using HPLC-HG-ICPMS. MtDNAcn, TL, and genot
There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each produc
The arsenic adsorption characteristics of a macroporous polymer coated with coprecipi-tated iron-aluminium hydroxides (MHCMP) is evaluated in this study. The MHCMP had a maximum adsorption capacity of 82.3 and 49.6 mg As/g adsorbent for As(III) and As(V) ions respectively. Extended X-ray Absorption Fine Structure (EXAFS) confirmed that binding of As(III) ions took place on the iron hydroxides coat
We study the effect of managerial power on CEOs' tendency to imprint their personal leverage preferences upon the firms they manage. Using a unique data source that allows us to measure personal wealth and indebtness in great detail, we find a connection between CEOs' personal leverage and that of their firms. The connection is driven by the CEOs with a longer tenure and the CEOs who serve in a du
The 2010 population and housing census in Ghana revealed that more than half of the Ghanaian population lived in urban centers. Critical to the phenomenon of urbanization is the question of how to sustainably feed the urban population especially the urban poor as rapid urbanization has the tendency to urbanize poverty. This has led to renewed policy debate about the implications of farming in citi
National accounts suggest that the Common Pochard Aythya ferina was an uncommon breeding bird throughout western Europe before 1850. Extensions to the breeding range in the late 19th century were potentially aided by the rapid development of managed fish-ponds in eastern Europe, which provided suitable novel habitat at that time. Expansion into western Europe followed in subsequent decades. Wetlan
