The high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. Studies show that there are different ways of reducing the power variability and therefore stabilize the energy
The increasing share of weather-dependent renewable energy in the European electricity system, as a consequence of the European Union’s climate ambitions, has led to increased spot price volatility, negatively affecting consumers due to unpredictability. This case study assesses how flexibility (including power-heat cross vector flexibility) in residential buildings can affect annual costs, emissi
Parasites play a fundamental role in explaining variation in population dynamics in wild ecosystems while also acting as a better model-system to study similar or related human infections. Since the late 1800s, malaria parasites have played a crucial role in vector-borne disease research. Many intrinsic and environmental factors can affect the level of infection transmission and prevalence among a
Old Scots pine (Pinus sylvestris L.) trees provide important habitat structures in boreal forest ecosystems, yet long-term intensive forest management in Sweden has made such trees increasingly rare and difficult to locate across large forest landscapes. Although field-based inventories can identify old trees reliably, they are time-consuming, costly, and spatially limited. This creates a need for
Idén till det här examensarbetet föddes när vi tillsammans tillbringade en termin i London för snart tre år sedan. Vi bodde nära Hackney City Farm, en stadsbondgård i östra London. Ett stenkast från bullrande vägar och röda dubbeldäckare fanns får, kor, getter, åsnor, höns och grisar mitt i stan. Vi blev berörda och fascinerade av närheten mellan djur och människa i en urban miljö. I vårt examensInitially the idea for this thesis was born when we spent a semester together in London about three years ago. We lived close to Hackney City Farm, in the heart of eastern London. Within a stone’s throw from noisy roads and red double-deckers there were sheep, cows, goats, hens and pigs right in the middle of the city. We were fascinated and inspired by the closeness of animals and humans in a ver
Purpose: The purpose of this study is to develop an understanding of consumers' perception of heritage in luxury brands online. This will be investigated from a consumer perceived value perspective, with regard to the following aspects of value; social, economic, functional and affective. Methodology: An epistemological and ontological foundation guides the research approach of qualitative so
Defective logic on Furutorpsgatan - An identification of present problems and proposed measures Helsingborg City is in the progress to make new maintenance measures on Furutorpsgatan. In relation to that, improvements to the streetscape, is also planned. Therefore a description on which problems that occurs with the current design of Furutorpsgatan, and possible measures to improve the situation h
In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues. This thesis aims to present a compreh
Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform th
Visst vore det fint om vi kunde producera nödvändiga kemikalier mer effektivt, förse alla människor med de läkemedel de behöver till en lägre kostnad än vad som är möjligt idag, och förhindra översvämningar i stadsmiljö? Men vad har dessa tre ting gemensamt, egentligen? Jo, att man kan optimera de olika processer som ligger bakom alla tre! Processer finns i princip överallt i världen, komplexa som eComplex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. Computer-aided optimization therefore lends itself as a viable alternative,
We know now that discs of gas and dust, so-called protoplanetary discs, form planets as side-products of the naturally occurring star formation process throughout the Milky Way. Young, growing planets in such discs are commonly referred to as protoplanets. In about 10\% of the so-far observed stars, this planet formation process leads to the occurrence of giant planets, such as Saturn, Jupiter, or
BACKGROUND: A comprehensive overview of treatments of common fractures is missing, although it would be important for shared decision-making in clinical practice. The aim was to determine benefits and harms of surgical compared to non-surgical treatments for traumatic skeletal fractures. METHODS: We searched Medline, Embase, CINAHL, Web of Science, and CENTRAL until November 2018, for randomized t
Concerns regarding environmental issues have led to increasing efforts for investigating sustainable production routes for the future industry that is based on renewable resources. Among the biobased chemicals, the C3-chemicals 3-hydroxypropionaldehyde (3-HPA), 1,3-propanediol (1,3-PDO) and 3-hydroxypropionic acid (3-HP), have been identified as top candidates for the chemical industry. Lactobacil
Objective: To describe the clinical and ultrasound characteristics of ovarian pure clear cell carcinoma. Methods: This was a retrospective study involving data from 11 ultrasound centers. From the International Ovarian Tumor Analysis (IOTA) database, 105 patients who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 1999 and 2016 were identified with a
The GHG-CCI project is one of several projects of the European Space Agency's (ESA) Climate Change Initiative (CCI). The goal of the CCI is to generate and deliver data sets of various satellite-derived Essential Climate Variables (ECVs) in line with GCOS (Global Climate Observing System) requirements. The "ECV Greenhouse Gases" (ECV GHG) is the global distribution of important climate relevant ga
Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. Sandy coasts are dynamic systems. Thus, risk assessments and coastal manage
Although prior falls are a well-established predictor of future fracture, there is currently limited evidence regarding the specific value of falls history in fracture risk assessment relative to that of other clinical risk factors and bone mineral density (BMD) measurement. We therefore investigated, across the three Osteoporotic Fractures in Men (MrOS) Study cohorts, whether past falls predicted
The ability of intrahippocampal grafts of fetal septal-diagonal band tissue, rich in developing cholinergic neurons, to ameliorate cognitive impairments induced by bilateral fimbria-fornix transections in rats was examined in three experiments using the Morris water-maze to test different aspects of spatial memory. Experiment 1. Rats with fimbriafornix lesions received either septal cell suspensio
Objective: The purpose of the study was to compare in prospective randomized fashion a manually sutured esophagogastric anastomosis in the neck and a stapled in the chest after esophageal resection and gastric tube reconstruction. Summary Background Data: Despite the fact that all reconstructions after esophagectomy will result in a cervical or a thoracic anastomosis, controversy still exists as t
Intramyocellular triacylglycerol (TG) is an important energy store, and the energy content of this depot is higher than the energy content of the muscle glycogen depot. It has recently been shown that the mobilization of fatty acids from this TG pool may be regulated by the neutral lipase hormone-sensitive lipase (HSL). This enzyme is known to be rate limiting for intracellular TG hydrolysis in ad
