In the present work Optimal Power Flow (OPF) with minimum net work losses for Iraqi National Super Grid (400kv) INSG which consist of 19 load buses and 6 generating buses was studied. The losses were calculated and compared with that in case of ordinary load flow which is equal to 37592 MW according to data of generation and load on 2/1/2003.Mathematical model using Lagrange method programmed in M

Fragmentation, as one of the most distinct characteristics of agricultural landscapes worldwide, has resulted in a diversity of ecological consequences. It remains as a gap in the literature on how provisioning service changes in association with agricultural fragmentation and land use management. Addressing such a gap at a national level should provide essential insights for policymakers. This pa

Background and purpose — Total knee arthroplasty (TKA) has increased substantially in Sweden. We quantified the relative risk for TKA in the Swedish population for different BMI categories and age groups to investigate whether the continued increase in TKA is attributable to increased prevalence of obesity and elderly people in the population, and to put forward model predictions for coming needs

Hydropower makes up nearly half of Sweden's electrical energy production. However, the distribution of the water resources is not aligned with demand, as most of the inflows to the reservoirs occur during the spring flood period. This means that carefully planned reservoir management is required to help redistribute water resources to ensure optimal production and accurate forecasts of the spring

The research evaluated retrofitting options for a threestory church community building in Grevie, Sweden, assessing the impacts on energy efficiency, life cycle cost, and environmental concerns. An energy model was generated in IDA ICE to simulate the building performance. Various improvements were tested in two separate retrofit package scenarios. They had the following measures in common: the ad

Dr Lisbeth NilssonLearning objectives:1. Describe at least three essential aspects of the facilitating approach.2. Explain why these aspects can facilitate optimal outcomes of intervention.3. Evaluate usefulness of the universal facilitating approach in your own practice.Session description:The process of learning joystick-use and training strategies for each phase in the process were identified i

In this study doctoral students in psychology and social anthropology/ethnology were interviewed as to their selection of research problem for their Ph.D. thesis. From the perspective of activity theory it is suggested that the research problem can profitably be seen as the object of activity in research. Graduate students’ selection of a research problem was analyzed as a process occurring over t

Background Primary hyperparathyroidism (pHPT) is associated with an increased mortality attributable to cardiovascular disease (CVD), suggested to be alleviated by surgery. The exact mechanism of the beneficial influence of parathyroidectomy on survival is unknown. Furthermore, studies suggest that there is no increased mortality compared to the mortality rate in the general population during rece

Maternal intrauterine enterovirus infection during pregnancy increases the risk for the offspring to develop type 1 diabetes mellitus. Type 1 diabetes mellitus and autoimmune thyroiditits (AIT) are closely linked. A common pathogenetic factor is possible. The objective of this study was to investigate a possible association between maternal enterovirus infection during pregnancy and the developmen

Creating efficient public transport systems that attract users is a challenging task in contexts where the control of public transport is divided between various actors. Recent research on public transport has therefore seen increasing focus on issues like coordination, collaboration and steering in complex governance settings. However, more is known about what needs to be done than how to impleme

Adeno-associated virus (AAV) capsid modification enables the generation of recombinant vectors with tailored properties and tropism. Most approaches to date depend on random screening, enrichment, and serendipity. The approach explored here, called BRAVE (barcoded rational AAV vector evolution), enables efficient selection of engineered capsid structures on a large scale using only a single screen

This study aimed to explore the value of synchrotron-based phase-contrast microcomputed tomography (micro-CT) in pulmonary vascular pathobiology. The microanatomy of the lung is complex with intricate branching patterns. Tissue sections are therefore difficult to interpret. Recruited intrapulmonary bronchopulmonary anastomoses (IBAs) have been described in several forms of pulmonary hypertension,

Next to the redesign of industrial products and processes, sustainable business model innovation is a strategic approach to integrate environmental and social concerns into the objectives and operations of organizations. One of the major challenges of this approach is that many promising business model ideas fail to reach the market, which is needed to achieve impact. In the literature, the issue

d-Amino acids are increasingly being recognized as important signaling molecules in mammals, including humans. d-Serine and d-aspartate are believed to act as signaling molecules in the central nervous system. Interestingly, several other d-amino acids also occur in human plasma, but very little is currently known regarding their function and origin. Abnormal levels of d-amino acids have been impl

Ochre, waste iron sludge from the treatment of iron rich groundwater for potable use, makes up a significant waste problem. Furthermore, wastewater treatment plants with enhanced biological phosphorus removal and the digestion of sludge are in lack of iron for the prevention of hydrogen sulfide production and the release of phosphorous during anaerobic digestion. Thus, the addition of ochre to ana

Denna sammanläggningsavhandling bygger på den kritiska teorins ambition att som en motbild till rådande läge skapa en bild av hur ett frigörande och i politiskt avseende realistiskt alternativ skulle kunna se ut, ett alternativ som innebär att personer som har utsatts för sexuellt våld får ett erkännande och kan delta i samhällslivet på lika villkor som andra. Mer specifikt är syftet att förstå hThe compilation dissertation is shaped by the ambition of Critical Theory, which is to imagine an alternative and emancipatory political reality to the status quo, where people who have been subjected to sexual violence are recognised and enjoy parity of participation in social life. More specifically, it aims to understand how victim-survivors of sexual violence in Iceland perceive, experience, a
