This review of the history of ultraviolet photobiology focuses on the effects of UV-B (280-315 nm) radiation on terrestrial plants. It describes the early history of ultraviolet photobiology, the discovery of DNA as a major ultraviolet target and the discovery of photoreactivation and photolyases, and the later identification of Photosystem II as another important target for damage to plants by UV

This article explores the quest among contemporary pentecostal migrants from mainland Tanzania in Zanzibar to become “saved” Christians. The analysis of a set of techniques and processes applied in developing and keeping faith reveals high levels of suspicion and doubt connected to the perceived presence of evil in the Zanzibari environment, which, in turn, is linked to a fear of losing salvation.

Obesity hypoventilation syndrome (OHS) is often diagnosed late. The aim of this study was to analyse gender differences at initiation of long-term mechanical ventilation (LTMV) in patients with (OHS), to analyse gender differences in treatment effect and to study how the prescription of LTMV due to OHS has changed over time.

In LTE base-stations, RoHC is a processingintensive algorithm that may limit the system from serving a large number of users when it is used to compress the VoIP packets of mobile traffic. In this paper, a hardware-software and a full-hardware solution are proposed to accelerate the RoHC compression algorithm in LTE base-stations and enhance the system throughput and capacity. Results for both sol

Human α-lactalbumin made lethal to tumor cells (HAMLET) and equine lysozyme with oleic acid (ELOA) are complexes consisting of protein and fatty acid that exhibit cytotoxic activities, drastically differing from the activity of their respective proteinaceous compounds. Since the discovery of HAMLET in the 1990s, a wealth of information has been accumulated, illuminating the structural, functional

Various biological tissues are designed to optimally support external loads for complex geometries and mechanobiological structures. This results in complex microstructures of such materials. The design of, for instance, (healthy) arteries, which are in the focus of this work, is characterised by a residually stressed fibre-reinforced multi-layered composite with highly non-linear elastic response

In Meru, Tanzania, changing land/labour ratios have, for over a century, been the main driving force in a farm intensification process. The construction and expansion of irrigation systems, increased use of farm inputs and transfer from low- to high-value agricultural crops have enabled smallholders to improve their land productivity. Technological change has been accompanied by institutional chan

BACKGROUND Genome-wide association studies have identified several genetic loci associated with variation in resting heart rate in European and Asian populations. No study has evaluated genetic variants associated with heart rate in African Americans. OBJECTIVE To identify novel genetic variants associated with resting heart rate in African Americans. METHODS Ten cohort studies participating in th

Benchmarking has received much attention in local government. However, since benchmarking within a networking environment is quite a recent phenomenon, there is a need for better understanding of the impact of these networks on local government. This article describes municipal benchmarking networks and analyzes and categorizes variations in action and performance among municipalities participatin

The energy use for maintaining comfortable indoor temperatures are to a certain extent dependent on the thermal storage capacity of materials in contact with the indoor air. This article describes a conceptual model for investigating the effects of increasing the thermal storage capacity of building materials. A building is modeled as an exterior wall, an indoor air volume and a thermally heavy in

The ash cloud of the Eyjafjallajokull (also referred to as: Eyjafjalla (e.g. Schumann et al., 2011), Eyjafjoll or Eyjafjoll (e.g. Ansmann et al., 2010)) volcano on Iceland caused closure of large parts of European airspace in April and May 2010. For the validation and improvement of the European volcanic ash forecast models several research flights were performed. Also the CARIBIC (Civil Aircraft

Temperature management for patients comatose after cardiac arrest has been an integral component of postcardiac arrest care for the last decade. In this review, we present recent findings and discuss implications for future trials.

We examined the epidermal gene expression during the proliferative phase of wound healing. Matrix metalloproteases were the group of proteases most prominently up-regulated in skin wounds, whereas serine protease inhibitors were the most strongly up-regulated protease inhibitors. Furthermore, we found down-regulation of genes involved in the extrinsic pathway of apoptosis. This together with the u

Hyperalphalipoproteinemia, as observed in patients who are either homozygous or heterozygous for cholesteryl ester transfer protein (CETP) deficiency, has been shown to be associated with striking changes in apolipoprotein size distribution, namely, of high-density lipoprotein (HDL) and HDL-like particles. We compared the effect of varying degrees of CETP activity on the HDL apolipoprotein profile

Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant-pollinator networks from 28 studies representing diverse biomes worldwide. We show that the potential for one plant species to influence another indirectly via shared pollinators was greater for plants whose resources were mo

Objective. To describe vascular events during an 8-year followup in a multicenter systemic lupus erythematosus (SLE) inception cohort and their attribution to atherosclerosis. Methods. Clinical data, including comorbidities, were recorded yearly. Vascular events were recorded and attributed to atherosclerosis or not. All of the events met standard clinical criteria. Factors associated with atheros

Fox Sparrows (Passerella iliaca (Merrem, 1786)) and Song Sparrows (Melospiza melodia (A. Wilson, 1810)) cohabit on many islands along the Pacific coast of North America, and previous studies suggest that they rely on similar prey types. We used delta C-13 and delta N-15 stable isotope analysis on blood collected from breeding adults of both species in each of two habitats on Triangle Island, Briti

Case studies are largely used for investigating software engineering practices. They are characterized by their flexible nature, multiple forms of data collection, and are mostly informed by qualitative data. Synthesis of case studies is necessary to build a body of knowledge from individual cases. There are many methods for such synthesis, but they are yet not well explored in software engineerin
