High efficiency, environmental friendliness, low operation and maintenance costs, and the lowest possible impact on the environment are some of the requirements of sustainable energy production. In the selection of new power generation systems, a number of steps have to be taken into account in order to meet these requirements. Here, the first law analysis has been implemented and investigated, fo

The aim of this chapter is to discuss global environmental change (GEC) through the social construction of nature and notions of authenticity. We will discuss the social construction of nature in a specific context, namely that of different kinds of nature-based tourism. The argument will revolve around what we perceive as a shift in focus from the image of nature as thing to nature as experience,

Drying is one of the most energy intensive and common operations in the chemical and process industries. Scope for energy recovery is substantial, particularly from the latent heat of the exhaust moist air. Using real operating data from a major Swedish mill, optimal energy conservation strategies were investigated using different heat pump systems in paper drying. Simulation results are compared

Popular Abstract in English Malnutrition and micronutrient deficiencies continue to be a major health problem, especially in rural areas in developing countries. It is of great importance to have reliable data about the existing deficiencies, and also about their main causes, for the designing and developing of efficient nutritional strategies in order to overcome nutritional problems. Bolivia is While originally, protein-energy deficiency was considered the main factor of malnutrition, it is now understood that micronutrient deficiencies play a fundamental role in a variety of health and disease outcomes. Zinc and iron deficiencies are still highly prevalent in low-income countries, whereas insufficient intakes and diets with low mineral absorption are the major causes. Sustainable and fe

Objective. To correlate cervical and amniotic fluid cytokines and macrophage-related chemokines to the development of histological chorioamnionitis (HCA) in patients with preterm labor (PTL) and preterm prelabor rupture of the membranes (PPROM). Study design. Cervical and amniotic fluid interleukin (IL)-6, IL-8, IL-18, monocyte chemotactic protein (MCP)-1, MCP-2, and MCP-3 from pregnant women (at

Altered DNA methylation is often seen in malignant cells, potentially contributing to carcinogenesis by suppressing gene expression. We hypothesized that heritable methylation potential might be a risk factor for breast cancer and evaluated possible association with breast cancer for single nucleotide polymorphisms (SNPs) either involving CpG sequences in extended 5'- regulatory regions of candida

The study investigates the relationship between drought and vegetation variations in three main basins of western and southwestern of Iran, using the comprehensive approach of time-series analysis, Standardized Precipitation Index (SPI), and anomaly calculation. A total of 30 ground stations’ daily meteorological data and the MODIS 16-day composite NDVI products (2000–2017) were used in this case.

Magnetic sensing is used to structure every-day, non-migratory behaviours in many animals. We show that crayfish exhibit robust spontaneous magnetic alignment responses. These magnetic behaviours are altered by interactions with Branchiobdellidan worms, which are obligate ectosymbionts. Branchiobdellidan worms have previously been shown to have positive effects on host growth when present at moder

Background: The built environment needs to be designed so that all people can participate in the activities they want and need to do. Yet, accessibility is difficult to put into practice, and accessibility issues tend to be overlooked in the building and planning processes. Objectives: The aim of this scoping review was to summarize the research front in the area of accessibility to public buildin

Beginning in the 1890s, workers’ associations and social-democratic activists in Sweden developed a series of People's Parks (Folkets parker) that extended across the length and breadth of the country. By the the mid-twentieth century, nearly every city, town, and village boasted its own People's Park. Built for relaxation and recreation, as well as for political agitation, Folkets parker also rep

Background: Cystic fibrosis (CF) is most common in populations of Northern European ancestry where the F508del variant predominates. In 2020, Iceland became a member of the European Cystic Fibrosis Society Patient Registry, and we launched an epidemiological study of CF in Iceland. The study aimed to determine the prevalence and the genetic variants present in the country. Furthermore, we aimed to

Background and Objective: Fentanyl is an opioid commonly used to prevent and treat severe pain in neonates; however, its use is off label and mostly based on bodyweight. Given the limited pharmacokinetic information across the entire neonatal age range, we characterized the pharmacokinetics of fentanyl across preterm and term neonates to individualize dosing. Methods: We pooled data from two previ

Numerous imaging methods have been developed over recent years in order to study materials at the nanoscale. Within this context, scanning X-ray diffraction microscopy has become a routine technique, giving access to structural properties with sub-micrometre resolution. This article presents an optimized technique and an associated software package which have been implemented at the ID01 beamline

Background: The predictive effects of change patterns of sleep problems on mental health after a long-term disaster remain poorly known. We examined the change patterns of sleep problems after the Wenchuan earthquake, and tested whether specific sleep-related change patterns could predict mental health problems (posttraumatic stress disorder [PTSD], anxiety, and depression) in the 10 years after W

This meta-analysis aims to evaluate the long-term survival and prognostic factors in patients with metastatic small intestine neuroendocrine tumors (siNETs). Patients with siNETs usually present with advanced disease, limiting curative treatment options. The overall survival seems favorable compared to other cancers, but differences in terminology, lack of consistent coding, conflicting results fr

Chromosome abnormalities, in particular translocations, and gene fusions are hallmarks of neoplasia. Although both have been recognized as important drivers of cancer for decades, our knowledge of the characterizing features of the cytobands involved in recombinations is poorly understood. The present study, based on a comparative analysis of 10 442 translocation breakpoints and 30 762 gene fusion

The removal of natural organic matter (NOM) from boreal lake water by a novel capillary nanofiltration (NF) membrane was predicted using a computational fluid dynamics (CFD) modelling approach. The 2-dimensional axis-symmetric model was based on a 48 m3/day NF pilot plant operating in cross-flow mode on water containing 8 mg/L total organic carbon (TOC) at fluxes ranging from 10 to 25 L/m2/h and v

In vivo microdialysis was used to monitor noradrenalin (NA) release in the rat hippocampus, sensorimotor cortex and amygdala in response to seizures induced by electrical kindling stimulation in the hippocampus. Generalized seizures increased NA output in the hippocampus five-fold above baseline level (as assessed with 2-min sampling periods). The peak value was seen 2 - 4 min after onset of seizu
