Today there is a high focus on the energy use when constructing new buildings. This mainly depends on the increased regulations and energy classifications that have been issued. Because of this, studies have shown that mechanical cooling in office environments leads to high energy consumption and service costs. This has led to an increased interest in analyzing if cooling only through ventilation

Cooked ham is a particularly popular cured meat product. Nonetheless, meat consumption constitutes a controversial issue, as researchers correlate red and cured meat with the development of colorectal cancer. One of the main compounds of the cured cooked ham is nitrite. Although, its residual amount in products is considered as responsible for the formation of N-nitrosamines and the provocation of

Arable land is a valuable natural resource. In Iceland the total size of potential arable land has not been determined but preliminary estimates vary from 420 ha to 15000 ha. These have been based on different definitions of potential arable land and assumptions for minimum continuous land area. In 2010 the Farmers Association of Iceland concluded that there was a need for a standard for evaluatin

De svenska fåmansföretagsreglerna infördes för att förhindra att upparbetade arbetsinkomster i ett företag tas ut till lägre beskattning genom utdelning eller kapitalvinst. Bestämmelserna återfinns i 56–57 kap. IL och reglerar i vilken omfattning en delägare med kvalificerade andelar i ett företag får ta ut tillgångar ur företaget i inkomstslaget kapital och till vilken del dessa istället ska beskThe Swedish regulations of closely held companies were passed in order to prevent income shifting from labour income to capital income and thereby lowering the marginal tax rate. The rules are found in the 56th and 57th chapters of the Income Tax Act and constitute an income splitting system, regulating how income from qualified shares is divided and taxed as capital income and income from employm

Ökande andel småskalig solproduktion introduceras i elnäten, detta medför möjligheter och utmaningar för nätägare. I detta arbete har möjligheten undersökts om småskalig solproduktion kan bidra till att upprätthålla spänningen i nätet vid trefasiga kortslutningar. I dagsläget är det många privatägare som installerar solceller. Denna utveckling har pågått länge, men de senaste åren har intresset sThe focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-

Läkemedelstransportering med lipidnanopartiklar (LNP), särskilt svampfas lipidnanopartiklar, har varit intressanta på grund av dess möjlighet att inkapsla läkemedel och överföra läkemedlet genom cellmembranet. Svampfas LNP formuleringen kan påverkas av lipidens molekylära struktur, temperaturen, pH-värdet, utspädningen, bufferten och existerandet av en stabilisator. Projektets syfte var att ersättDrug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. This project aimed

The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. This study followed these directives and guidelines to collect the required data and employed the NORD2000 model to simulate traffic no

- Kan man förutse en kräms hållbarhetstid utifrån dess tjocklek? I detta examensarbete har de reologiska- och texturegenskaper undersökts hos två typer av krämer, en med Cetostearylalkohol som förtjockare, och en med ett mer naturligare alternativ som Xanthan Gum, samtidigt som stabiliteten hos dessa två krämer har undersökts under längre tidsperiod. Att utveckla nya läkemedel är en tidskrävandeThe aim of this project was to develop analytical methods for characterizing rheological behavior of creams. The rheological methods of shear ramp, thixotropy, amplitude sweep, and frequency sweep, as well as texture analysis were initially developed at LTH and later transferred to Galenica. For this project two series of emulsions were formulated and used as test subjects for these methods. One u

För att förstå skatterättens effekt på det svenska samhället krävs kontinuerlig utredning och utvärdering av regleringarna. Med anledning av detta undersöks i denna uppsats fåmansföretagsbeskattnings effekt på samhället utifrån ett neutralitetsperspektiv. Genom en fördjupad analys klargörs hur neutrala fåmansföretagsbeskattningens regleringar kan anses vara vid val av associationsform. Med dennTo understand the effect of tax law on the Swedish society, continuous investigation and evaluation of regulations is required. With this in mind, this thesis investigates the effect of close company taxation on society from a neutrality perspective. Through a deep analysis, it becomes clear how neutral the regulations for close company taxation are when choosing the form of association. Based on

Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts. This

As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). This means that clear-cut areas don’t act as the carbon sin

För skapa ett transporteffektivt samhälle kommer kollektivtrafiken att spela en allt större roll i framtidens transportsystem. Om kollektivtrafiken utgör ett reellt alternativ till bilen kan den bidra till både sänkta utsläpp av växthusgaser och marknära partiklar och bidra till en mer effektiv användning av stadens yta. Speciellt i större städer ställs allt högre krav på en effektiv markanvändninIn order to create a more transport efficient society public transport has to play an even bigger role in the future transportation system. If public transport constitutes a realistic alternative to the car it can contribute to both the decrease of greenhouse gases and particles harmful for health, as well as contributing to a more efficient use of city spaces. Especially in larger cities ever hig

The purpose of this thesis is to produce an example of a solution to the problem with varying space requirements in divorced families living one-and two-family houses in Sweden. We have focused our work on solving this with a stand-alone complementary building which contains all the critical functions a dwelling should have. To facilitate and make the investment more realistic the building should

Skogsskador och skogsdöd är ett växande problem i Europa. "Svarta Triangeln", som ligger i bergsområdet där Tysklands, Tjeckiens och Polens gränser möts, är en av de värst drabbade områdena. I dagsläget saknas kunskap för att kunna förklara skogsskadorna helt och hållet, men markförsurningen i området, som orsakas främst av förbränning av svavelrikt kol i de många kolkraftverken, är trolForest decline is an increasing problem in Europe. "The Black Triangle" area, situated in the mountainous region where the borders of Germany, the Czech Republic and Poland meet, is one of the worst damaged areas. The reasons for the forest dieback are not fully understood, but the soil acidification caused by the burning of sulphur rich coal in the region is considered a major cause. To

Populärvetenskaplig sammanfattning: De kvartära landskapsformerna i södra Sverige skapades till stor del under och i samband med avsmältningen av den senaste inlandesisen. Skåne blev isfritt för ca 13 000 år sedan med en isavsmältning i nordvästar Skåne mot NO. I samband med denna avsmältning skapades ett småkuperat moränlandskap, plana slätter, mindre kullar och åsar. Åsarna har bildats av materiThe purpose with this study is to identify and examine heterogeneities within the ground, which is important for the groundwater flow on a more local scale. Investigation of the geology within an area is normally done through observations in field, combined with studies of geological maps and documented drillings. Depending on drilling methods, varying results are obtained but often with a good re

Under vissa typer av operationer, till exempel då kärlen kring hjärtat opereras, använder sig läkare av en speciell typ av röntgenmaskin för att orientera sig inuti kroppen, så kallad genomlysning. För att undgå att öppna upp bröstkorgen på patienten går läkarna in med små verktyg i kärlen via ljumskarna och upp till hjärtat. Eftersom läkarna står så nära patienten träffar en del av strålningen de

They have refineries in several parts of the world and their largest production facility is situated in Nynäshamn, Sweden. They also have oil depots in all continents and their largest depot is located in Antwerp, Belgium. In the beginning of 2007 Nynas introduced a new type of transformer oils, called Nova grade

Abstract Objective: The small intestinal epithelium is a highly complex system continuously renewed by a process involving cell proliferation and differentiation. In mammals, the physiological function of intestine is not fully mature at birth, and many factors could accelerate gut maturation. In the current study we hypothesized that the pancreatic enzymes could be one of such factors. In the sa
