De senaste tio åren har antalet sökta bygglov för småhus med träregelstomme mer än fördubblats. I dagsläget finns inget allmänt krav att säkerställa horisontalkapacitet för småhus men är något som beställaren kan efterfråga och som många konstruktörer någon gång upplevt problematiskt. Projekteringsfasen kan bli tidskrävande där lösningar för att fastställa kapacitet mot vindlast blir dyra och kompIn the last ten years, the number of building permits applied for houses with timber frame structure has more than doubled. Today, there is no general requirement to establish horizontal capacity, but is something that can be demanded and that many structural engineers have occasionally experienced as problematic. The design phase can then be time-consuming, where solutions for determining capacit

This study used the urban context of Brunnshög, Sweden as a real case study to assess non-visual daylight conditions in urban environments. More precisely, the work was focusing on how the light spectrum – through surrounding façade colour and window type – can have an impact on the circadian potential. A one-bedroom apartment opening onto a courtyard on the ground floor and the same apartment on

En grundvattenundersökning i ett område präglat av vattenrelaterade problem. Staden Cochabamba i Bolivia står inför flera vattenrelaterade utmaningar såsom brist på ytvatten, en ökande vattenanvändning, urbanisering och en sjunkande grundvattennivå. Samtidigt råder det en brist på kunskap angående de processer som påverkar grundvattnet i området. Något som detta examensarbete ämnar att förändra. The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t

Studien syftar till att beräkna det gröna, blå och grå vattenfotavtrycket vid odling och produktion av höstvete och tre fallstudier av höstvete-produkter; drivmedelsetanol, kärnvetemjöl och makaroner. Beräkningarna har utförts för Sverige under perioden 2008-2010 och täcker ungefär 80 % av den svenska produktionen av höstvete under de berörda åren. Södra Sverige delades in i 18 klimatzoner för vilThis study attempts to calculate the green blue and gray water footprint of the crop production of winter wheat and three derived winter wheat products: liquid fuel ethanol, wheat flour and macaroni. The calculations were done for Sweden for the period 2008-2010, covering an average of 80% of the annual winter wheat production. The south of Sweden was divided into 18 climate zones for which suffic

Background: Epidemiological studies have shown that many welders experience respiratory symptoms. During the welding process a large number of airborne nanosized particles are generated, which might be inhaled and deposited in the respiratory tract. Knowledge of the underlying mechanisms behind observed symptoms is still partly lacking, although inflammation is suggested to play a central role. Th

BACKGROUND: Musculoskeletal (MSK) disorders are less likely to be reported as an underlying cause of death (UCD) and since cause of death studies are generally limited to the UCD, little is known about socioeconomic inequalities in MSK disorders as cause of death in the general population. Using multiple-cause-of-death data, we aimed to quantify and compare educational inequalities in musculoskele

Air pollution is responsible for one in eight premature deaths worldwide, and thereby a major threat to human health. Health impact assessments of hypothetic changes in air pollution concentrations can be used as a mean of assessing the health impacts of policy, plans and projects, and support decision-makers in choices to prevent disease. The aim of this study was to estimate health impacts attri

Due to the overpopulation in the main cities and shortage of water in Egypt, finding new possible reclamation areas becomes an urgent necessity. The area northwest of El Sadat city can be considered one of the most promising new reclamation areas. This study focuses on detecting the groundwater aquifers, delineating the best localities to drill groundwater boreholes, and evaluation of the groundwa

The book "Aqua-ecologic Functional Zoning of Songhua River Basin: Application Manual" introduces the technical methodology and detailed application instructions for aqua-ecologic functional zoning in Songhua River Basin in a systematic way in nine Chapters. Based on a general introduction of concept and in-depth contents of aqua-ecologic zoning and its methodology, this application manual addresse

The novel method of modification of polyethersulfone (PES) ultrafiltration membranes is proposed. This method involves the use of aqueous solutions of polyacrylic acid (PAA) of different molecular weights (Mn=5.1×103 g·mol–1, Mn=490×103 g·mol–1) as a coagulant in non-solvent induced phase inversion process (NIPS). Addition of PAA (0.05–1.5 wt%) to the coagulation bath leads to marked changes in pe

This study develops a framework for spatiotemporal modeling of dust storm source susceptibility in a critical case study, the Tigris-Euphrates River Basin, as a significant source of dust storms in the Middle East. The study period was divided into four periods, 2000–2004 (hydrological dry year), 2005–2007 (hydrological wet year), 2008–2012 (hydrological dry year), and 2013–2021 (hydrological wet

Eco-roofs are becoming popular for aesthetic reasons and also as units of stormwater systems. It is thought that such roofs with soil cover and vegetation reduces the total runoff, the peak flows and improves the quality of the roof water. Here are reported investigations of runoff from thin, 3-4 cm soil, extensive green roofs with sedum-moss in southern Sweden. The two-year study was performed on

Jordan has one of the lowest available water supplies in the world; meanwhile Jordan has seen large increase in population and refugee’s fluxes, leading to an increase in water demand [1]. To address this unprecedented water scarcity, Jordan’s water must be used where its social and economic value is highest. Jordan must treat and reuse virtually every drop of water. It is expected to have more th

Atmospheric particulate matter and dust from agricultural land significantly affect air quality and human health in nearby residential areas. To quantify these air pollutants, it is important to estimate the vertical atmospheric particulate matter PM2.5, PM10, and dust flux using observations and validated models. To the authors´ knowledge, this has previously not been performed for semi-humid agr

BACKGROUND: Workplace stressors, such as bullying, are strongly related to subsequent long-term sickness absence, but little is known of the possible physiological mechanisms linking workplace stressors and sickness absence. The primary aim of this study was to investigate to what extent cortisol levels were associated with subsequent sickness absence and if cortisol mediated the association betwe

Changes to the contemporary food system, including meals and eating patterns, have occurred quickly. One such change over the past 30 years has been the increase of commercially produced foods aimed at food allergies and intolerances and ‘free from’ dieting. The gluten free diet has recently emerged as a popular diet trend in Western countries, outpacing its origins as a treatment for celiac disea

Background: The main objectives of this study were to evaluate the concordance between self-reported and registry-reported information regarding family history of breast cancer (BC), ovarian cancer (OvC) and other types of cancer in first-degree relatives of patients with early onset BC, and to determine the frequency of mutation carriers and non-mutation carriers. The secondary objective was to d

Plant-based beverages are increasing in popularity and quinoa is an attractive option. A hygienic implication linked to the production of beverages from raw material originating from plants is the high microbial contamination. The safety of the product can be guaranteed by lactic acid fermentation, and by using a probiotic strain as starter culture for the fermentation, the final product will bene

This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th
