There is a significant infrastructure in the world for using liquefiedpetroleum gas (LPG). The fuel is used in many applications, spanningfrom heating to chemical processes as well as a vehicle fuel. To be able touse this infrastructure also after a transition from fossil to renewablesources, a technology for producing LPG from such resources (glycerol,cellulose etc.) is being developed. This repo
This thesis investigates III – V semiconductor nanowire (NW) arrays, with the aim to develop and improve NW photovoltaic devices. Solar cells made from arrays of NWs are investigated as candidates for next generation photovoltaics. They promise to deliver the high efficiencies of III – V planar semiconductor solar cells, while the cost of the cells could be significantly reduced, due to the much l
With the concern about global warming, air pollution and energy security, the prospect of using polymer electrolyte fuel cells (PEFCs) in future sustainable and renewable energy conversion systems has achieved substantial momentum. Dimensionless numbers can be determined before construction of a model is started, to make simple estimations on the transport processes, for example, within the porous
Inom Europa beskriver begreppet energifattigdom de kompromisser som hushållkan möta avseende att å ena sidan ha en tillräckligt uppvärmd bostad, och å andrasidan ha råd med övriga omkostnader. I Sverige har begreppet tidigare inte använts, och kanske heller inte behövts. Men i december 2021 steg elpriserna till nivåer som gjorde att vissa hushåll, där en rad riskfaktorer sammanstrålade, plötsligt
Effekten av vindkraftens tillväxt är att vi i dag producerar mer el än vad vi behöver även då vi lagt ner flera kärnkraftverk. Klimatomställningen via elektrifiering pekar på ett fördubblat elbehov till 2045. Detta kräver mycket ny elproduktion. Och potentialen att bygga ut ny vindkraft är tillräcklig för att täcka behovet. Ny kärnkraft kan också bidra men kan tidigast vara i gång 2030 om inte sen
Avdelningen arbetar med att skapa hållbara strukturer, processer och styrdokument inom berörda processområden vid Lunds universitet: arbetsmiljö, hälsa, lika villkor, kompetensförsörjning och kompetensutveckling. Avdelningen är ett stöd till universitetsledningen i arbetsgivarpolitiska ställningstaganden, vägleder, utbildar och genomför insatser inom avdelningens huvudområden utifrån gällande regeThe Division works on creating sustainable structures, processes and regulatory documents in relevant process areas at Lund University: work environment, health, equal opportunities, provision of expertise, and professional development. The Division acts as support for the University Management regarding decision-making in employer policy matters, provides guidance and training, and carries out in
Unhealthful lifestyles underpin much of the burden of cardiometabolic disease affecting contemporary societies. Our overarching objective is to discover and optimise measurable biomarkers that can be used to stratify patient populations into subgroups that can be treated more effectively with targeted lifestyle therapies, at lesser cost and with fewer adverse events than conventional approaches
Forskargruppen som leds av professor Kristina Sundquist är baserad inom ett dynamiskt forskningsinstitut, CPF (Centrum för Primärvårdsforskning) som grundades på fyra pelare: klinisk, epidemiologisk, samhällsvetenskaplig och experimentell forskning. Den forskning som gruppen utför är både klinisk och epidemiologisk, och dess huvudsakliga fokus är att besvara frågor relevanta för primärvården. ViktThe research group led by Professor Kristina Sundquist is based within a dynamic research institute, the CPF (Center for Primary Health Care Research) that was founded on four pillars: clinical, epidemiologic, social science, and experimental research. The research performed by the group is both clinical and epidemiologic, and its main focus is to answer primary health care-related questions. Key
Objectives: Depression is common but not always recognized and often undertreated among elderly. Cardiovascular diagnoses have been reported to be associated with depression. The study examined if this association could be confirmed in a frail elderly population. It also assessed the association between high depressive scores and certain health complaints and the use of certain drugs, respectively
ABSTRACT: BACKGROUND: Traditional patterns relating to how to handle pregnancy and birth are often challenged due to migration. The purpose of this study was to describe Middle Eastern mothers' experiences of the maternal health care services in Sweden and the involvement of their male partner. METHODS: Thirteen immigrant mothers from the Middle East who had used the maternal health services in Sw
A high frequency of IgA1-positive tumour cells was found in tissue micro-arrays of oesophagus, colon, testis, lung, breast, bladder and ovarian cancer. IgA1 was observed in the cytoplasm and the plasma membrane. A correlation was found between intra-tumour IgA1 and poor overall survival in a large cohort of bladder cancer patients (n = 99, p = 0.011, log-rank test). The number of IgA1-positive tum
IntroductionGovernment and public agencies in Sweden have promoted the expansion of eHealth. The strategy behind many of the eHealth services is to increase quality of care, enhance efficiency, patient empowerment and patient safety. Patient online access to their electronic health record (EHR) is one of the most important civic eHealth services. By 2017, all patients in Sweden will be able to acc
Gastroparesis is a well-known complication of diabetes mellitus, both in symptomatic and asymptomatic patients. Esophageal dysmotility has also been described, but is not as well-characterized. The etiology and effect of these complications need to be clarified. The aim of the present study was to evaluate esophageal and gastric motility, complications, gastrointestinal symptoms, and plasma biomar
In his recent work, Eco abandons his conventionalist theory of pictures, which was heavily censored by, among others, the present author. In so doing, however, Eco now goes to the other extreme, claiming that television images are like mirrors, which are no signs. It is my contention that Eco fails to come up with a more acceptable theory of iconicity. Since Eco is one of the few semioticians conc
Amassing the available solar energy over the Sahara desert, through the installation of a large-scale solar farm, would satisfy the world’s current electricity needs. However, such land use changes may affect the global carbon cycle, possibly offsetting mitigation efforts. Here a fully coupled Earth System model EC-Earth was used to investigate the impact of a Saharan solar farm on the terrestrial
