Waste heat recovery systems for power generation are gaining interest among the marine transport sector as a solution to accomplish the upcoming more restrictive regulations on emissions, and to reduce the total fuel consumption. In this paper we evaluate how a waste heat recovery system based on a regenerative organic Rankine cycle (rORC) could improve the performance of a passenger vessel. The c
Abstract A current problem in Sweden is the housing shortage. Especially young people are affected since there is a lack of small apartments. One way to increase the amount of smaller apart- ments is to retrofit unused lofts. To facilitate this type of reconstructions the Swedish parlia- ment voted for a legislative change on the first of July 2014. The change says that no elevator needs to be ins
Every year, a big number of Swedish municipalities market themselves through an Emigration fair in Holland, with the aim to attract Dutch workforce, or more generally, bring new inhabitants to their respective region. In the marketing campaigns, specific stereotypic images of Sweden emerge, that are said to be specifically attractive to the putative Dutch migrants. The municipal representation in
Due to the act on Energy Audits in Large Enterprises (EKL) that came into effect on the 1st of June in 2014, all larger companies are obligated to perform an energy audit every four years. Parallel to the audit performed at Alufluor AB this more detailed audit of the drying part of their process was carried out. This as the drying part is energy intensive and is responsible for the majority of the
This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. Matson, during an internship in collaboration with the Swedish National S
Denna uppsats behandlar frågeställningar rörande romska barn, dvs. barn med minoritetsstatus i LVU-ärenden (lagen om vård av unga). Uppsatsens syfte är att studera hur rättsväsendet hanterar LVU-ärenden som berör romska barn och att undersöka om rättsväsendet vidtar speciella åtgärder för att garantera de romska barnen sina minoritetsrättigheter. Uppsatsens har även två delysften, att kortfattat bThis essay deals with issues concerning the Romani children, i.e. children with minority status in LVU cases (the law on the care of youth). The essays main purpose is to study how the legal system handles LVU cases involving Romani children and to investigate if the judiciary is taking special measures to ensure the Romani children their minority rights. The essay also aims to briefly describe th
The European Union is expected to respond to world events every day and terrorist acts are predominate and often conducted by terrorist organizations or non-state actors. One of the most delicate cases is the Lebanese Hezbollah frequently resorting to violence and has over the last 20 years grown evermore important in the Middle East and Lebanon, thereby increasingly elevating the need for the EU
Deteriorating water quality is a challenge which affects people of the entire world, with a growing population and increased industrialization worldwide. The problem is especially apparent in many developing nations where water resource management must be improved to secure a future sustainable supply. This study was undertaken as a bachelor degree within the MFS-program funded by SIDA. The study
Outdoor climate has considerable impact on the indoor climate and it is therefore important to adapt the buildings to the climate. This thesis shows how to improve indoor climate in a climate which it is hot, dry in the summer and cold in the winter. My investigative unit is a middle class house in the town Baalbek in Lebanon and the purpose of the study is to come up with proposals on possible so
This thesis empirically investigates the question if US firm’s capital structures are stable over longer periods of time and which firm characteristics drive optimal leverage. The analysis is based on a Compustat panel data sample consisting of 2,900 US firms between 1985 and 2016. After analyzing the stability of firm’s capital structure via a “narrow band” and a “relative bucket approach” an err
The purpose of this study was to investigate how social workers, working with financial aid, creates participation for children and if their work has been affected by the legal enforcement of the Convention on the Rights of the Child and its children rights perspective. We used a qualitative method when interviewing in order to examine and find an answer to our purpose and question at issue. The r
NERICA, a new group of high-yielding and stress-tolerant upland rice varieties developed by the Africa Rice Center, is changing production strategies of many Ugandan households. This article contributes a better understanding of processes leading to NERICA-related household outcomes in Hoima District, Uganda, by examining patterns of intrahousehold production relations and their consequences for h
In late 2011 The Swedish Society of Radiation Physics formed a working group to concentrate on the Quality Assurance of modern radiation therapy techniques. The given task was to identify and summarise the different QA strategies in Sweden and also the international recommendations. This was used to formulate recommendations for practical guidelines within Sweden. In this paper a brief summery of
Browning of inland waters has been noted over large parts of the Northern hemisphere and is a phenomenon with both ecological and societal consequences. The increase in water color is generally ascribed to increasing concentrations of dissolved organic matter of terrestrial origin. However, oftentimes the increase in water color is larger than that of organic matter, implying that changes in the c
We investigated how the legacy of warming and summer-drought affected microbial communities in five different replicated long-term (>10 years) field-experiments across Europe (EU-FP7 INCREASE infrastructure). To focus explicitly on legacy effects (i.e. indirect rather than direct effects of the environmental factors), we measured microbial variables under the same moisture and temperature in a bri
Background and aims. Adverse events (AE) leading to discontinuation or dose-reduction of thiopurine therapy (TP) occur in 9-28% of patients with inflammatory bowel disease. 6-Thioguanine (6-TG) has been proposed as an alternative treatment in patients intolerant for azathioprine (AZA), but some concerns have been raised about drug safety. Methods. We evaluated in a prospective manner the tolerance
In this paper, a new approach for on-line monitoring and detection of abnormal readily biodegradable substrate (SS) and slowly biodegradable substrate (XS) concentrations, for example due to input of toxic loads from the sewer, or due to influent substrate shock load, is proposed. Considering that measurements of SS and XS concentrations are not available in real wastewater treatment plants, the S
A REE-bearing fluorosilicate from the Tommot REE-Nb deposit in Yakutia, Russia, described without a name in 1966, is characterized here as a new species, proshchenkoite-(Y), of the vicanite group of borosilicates. Wavelength-dispersive electron probe analyses gave the following empirical formula: (Y3.70REE7.54Ca1.55Na1.16Mn0.77Th0.10Pb0.01)(Sigma 14.83)(Fe0.832+M0.15Ti0.02)(Sigma 1.00)Ca-1.00 (P0.
This design researched and explored the new way of solar light use and deploying, on efficiency and usability levels. Recent research has shown that the solar energy has a potential impact on people1, which accounts for one of the most of the available renewable energy on earth. In this research, I decided to look deeply into the appliance of solar light systems, to make solar energy accessible fo
Today most companies have online sales channels. Most commonly have companies started offline and then later expanded online while others have started their business online through, for example, web shops. Even though we today are living in a high technology society, the existence of an offline sales channel is still needed. But what is the exact definition of a sales channel really? In today’s
