To further improve the flat-type loop heat pipe (LHP) performance, this study evaluates the practical potential of use of highly enhanced boiling structures. It is found that in our proposed new heat pipe (NHP) system, the working fluid from the evaporator outlet to the condenser inlet is in a liquid–vapor two phase flow, which is different from the classical LHP theory. A new P-T diagram is devel
Purpose: Sustainability is an area of increasing interest for industry and its stakeholders, and some companies now aspire to address sustainability issues (e.g. carbon emissions) at strategic and operational levels. As companies are exploring the issues, they attempt to embed sustainability in their planning and management systems. It is at this point that the domains of environmental concern and
Surface water is vital resources for terrestrial life, while the rapid development of urbanization results in diverse changes in sizes, amounts, and quality of surface water. To accurately extract surface water from remote sensing imagery is very important for water environment conservations and water resource management. In this study, a new Multi-Band Water Index (MBWI) for Landsat 8 Operational
Background: Biomarkers serve as a quantitative measure of brain injury and may predict cognitive outcome after cardiac arrest. This study investigates the association and predictive accuracy of acute changes in Alzheimer disease-associated biomarkers to cognitive outcome in cardiac arrest survivors.Methods: Retrospective study of the Target Temperature Management after Out-of-Hospital cardiac arreBackground: Biomarkers serve as a quantitative measure of brain injury and may predict cognitive outcome after cardiac arrest.

Solar-Induced Chlorophyll Fluorescence (SIF) can provide key information about the state of photosynthesis and offers the prospect of defining remote sensing-based estimation of Gross Primary Production (GPP). There is strong theoretical support for the link between SIF and GPP and this relationship has been empirically demonstrated using ground-based, airborne, and satellite-based SIF observation
Parallellt med den rådande Covid-19 pandemin råder en annan ”skuggpandemi” bakom stängda dörrar. Våld i hemmet har allt för länge varit ett nedprioriterat diskussionsämne och hur uppmärksammas våld som sker i det gömda och vilka är de ekonomiska, sociala och politiska konsekvenserna? I en rapport från kvinnojouren Unizon redovisas det att mäns våld mot kvinnor har ökat under pandemin och att en f
År 1926 färdigställde Processkommissionen sitt principbetänkande angående rättegångsbalkens ombildning. Kommissionen föreslog en form av förenklat förfarande, där enklare mål skulle kunna lagföras utanför domstolen. Den största anledningen till att ett enklare och snabbare förfarande ansågs behövas var för att avlasta domstolarna från en allt för tung arbetsbörda. Snabbspolat framåt, så reglerasIn 1926 a commission report about a new code of judicial procedure was completed. The commission suggested the introduction of a summary procedure for misconducts that did not need to be resolved by the court. The main reason for this procedure was that it would unburden the courts from a heavy workload. Fast forward to today, the summary procedure, penal order, is regulated in chapter 48 of the
Popular Abstract in Swedish Introduktion: 1) Prostatacancer Prostatakörteln Prostatan, eller blåshalskörteln, är belägen strax nedanför urinblåsan hos män, där den omsluter urinrörets översta del. Denna, i normala fall valnötsstora körtel, producerar ett sekret som utgör en del av sädesvätskan. Hos yngre män uppstår ibland infektioner i prostatakörteln. Många äldre män får en godartad prostatafThis thesis is based on research concerning epidemiological, clinical, and psychological aspects of familial and hereditary prostate cancer. Epidemiology: Male first-degree relatives of prostate cancer patients had a three-fold increased prostate cancer risk. The risk was higher for relatives of younger patients than for relatives of older patients, most likely due to the effect of the higher pre
The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. Besides iron ore, steel scrap is the most important input raw material for
Background: Epidemiological studies that assess the health effects of long-term exposure to ambient air pollution are used to inform public policy. These studies rely on exposure models that use data collected from pollution monitoring sites to predict exposures at subject locations. Land-use regression (LUR) and universal kriging (UK) have been suggested as potential prediction methods. We evalua
Cancer is one of the main causes of death in the world, particularly in developing countries and is considered as a major public health problem. Radiation therapy has been an important modality for treatment of cancer for many decades. It can be used as a sole treatment modality or in combination with for example surgery, chemotherapy, hormone therapy and/or immune therapy. It has been calculated
Inferential models have long been used to determine pollutant dry deposition to ecosystems from measurements of air concentrations and as part of national and regional atmospheric chemistry and transport models, and yet models still suffer very large uncertainties. An inferential network of 55 sites throughout Europe for atmospheric reactive nitrogen (N-r) was established in 2007, providing ambien
Varför gör vissa bakterier oss sjuka men inte andra? Hur kommer det sig att vissa bakterier lyckas överleva och infektera särskilda delar av kroppen men väldigt sällan andra? Bakterier och människor har evolverat länge tillsammans och har därmed lyckats utveckla specifika angrepps och försvarsmekanismer mot varandra. Det är känt sedan tidigare att några bakterier uttrycker proteiner med förmågan Bacteria and humans have co-evolved since their common existence. They have thereby developed very specific defence and target mechanisms against one another. Understanding the complex biomolecular processes behind these interactions can be of great use for developing treatments against bacterial diseases. The aim of this thesis project was to verify, and introduce a model for understanding, the i

We investigate four different methods for background estimation in calcium imaging of the insect brain and evaluate their performance on six data sets consisting of data recorded from two sites in two species of moths. The calcium fluorescence decay curve outside the potential response is estimated using either a low-pass filter or constant, linear or polynomial regression, and is subsequently use
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, polluta
The oxygen-atom transfer reaction catalyzed by the mononuclear molybdenum enzyme dimethyl sulfoxide reductase (DMSOR) has attracted considerable attention through both experimental and theoretical studies. We show here that this reaction is more sensitive to details of quantum mechanical calculations than what has previously been appreciated Basis sets of at least triple-zeta quality are needed to
The quantification of species along environmental gradients has long been the subject of study regarding natural plant communities and, more recently, ecosystems disturbed by anthropogenic emissions of eutrophying and acidifying substances. We studied 527 sites in southern Swedish deciduous forests divided into two regions, with mean nitrogen depositions of 17 and 9 kg ha(-1) y(-1). The higher dep
