Energy analysis of a fruit drying plant in Adeiso, Ghana
The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit
drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying
process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity.
The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.
Anstaltspersonals erfarenheter och påverkan av hot och våld på arbetet : en kvalitativ studie
The aim of this paper was to describe the phenomenon of threats and violence within a Swedish penal institution. The study was thematized according to the three main research questions. These were as follows; The threats and violence prison staff have experienced in their workplace (I) how these experiences affected them in their work performances (II) and in their private life (III). By a qualitative design, in-depth interviews were carried out with four persons who are, or formerly have been, gainfully employed at a penal institution. Concepts from the theory of symbolic interactionism and a theory of human action have been used in the analysing process of this paper.
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Vägsaltets effekter på växter i urban- och offentligmiljö : ett växande problem
Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.
Näsnarens framtid i ett näringsstatusperspektiv
Eutrophication has been a problem in aquatic systems for a long time. It is well known that the key nutrient to control the eutrophication process is phosphorus. Lately, it has been possible to reverse the process and recover lakes from eutrophication.During a long time Lake Näsnaren in Katrineholms kommun, Södermanland, has been exposed of a large amount of phosphorus from the city's wastewater. The lake has a great value as a habitat of rare species but also a high recreation value for people living in Katrineholm and Södermanland. Lake Näsnaren is situated in a Natura 2000 area.
Den rådande tolkningen av samma eller likartad verksamhet : Konsekvenser vid generationsskiften i fåmansföretag
On the 26th of January 2010, the Supreme Administrative Court in Sweden gave five rulings which greatly affect the possibility to keep a close company within a family by transferring the ownership of the company to the next generation. The five rulings concern the interpretation of the prerequisite, same or similar activity, which can be found in section 57, clause 4 of the Swedish Income Tax Act. The prerequisite is fulfilled when an entire or parts of a business is transferred to another close company and the receiving company?s business activity is within the framework of the transferring company?s business activity or when the companies have a similar connection. Depending on which shares that are being evaluated, the prerequisite can refer to both the shares in the receiving or the transferring company. When the prerequisite is fulfilled, a standardized amount of the business income will be taxed as capital gains and the surplus will be taxed as earned income.
Vacuumassisterad sa?rbehandling pa? en ka?rlkirurgisk va?rdavdelning ? Utva?rdering av behandlingsresultat pa? olika sa?rtyper och hur patienter skattar sin sma?rta i samband med byte av VAC-svamp : En journalgranskningsstudie
Background: Vacuum assisted closure, VAC, is a method which can benefit wound closure. There are not many reliable studies about the effects of VAC in different types of wounds. Previous studies have shown that patients have experienced pain during dressing changes.Aim: The aim of the study was to survey in what kind of wounds the vascular surgery ward have been using VAC, to study the treatment process of VAC and how it has been documented and also to investigate if patients with VAC experienced pain during dressing changes.Method: The patients were chosen from a ledger, which contained 77 patients that had been treated with VAC on the vascular surgery ward. Data were collected with a journal survey protocol.Results: The result is based on 67 patients with a total of 79 wounds. VAC was shown to have a good effect on wound healing and infected surgical wounds were the most commonly wound category undergoing treatment with VAC.
Reducering av produktionstryck i A-linan : Förflyttning av produkt
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Odlingens och lagringens inverkan på utsädes grobarhet :
At seed-growing the aim is to produce a commodity with high germination capacity, good soundness
and purity, and also slight admixture of seeds from other species. The capacity of germination and the
vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases,
growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears
etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is
much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can
be due to the fact that the seeds are in rest of germination, i.e.
Får man skriva så här? : En feministisk undersökning av mottagandet i recensioner i svensk dagspress av fyra romaner med bekännelsekaraktär
The purpose with this thesis is to examine how four novels with a trait of confession written between 1996 and 2001 have been received in the Swedish daily press. This is done from a feministic perspective. The study is based on 36 reviews and the method which is used consists of a close-reading of the reviews, where the following questions are asked to the texts: Are there examples of reception in sexual analogies?; Are the novels ascribed a status of universality or are they considered to be something private?; How does the reviewers comment the exposure of the authors themselves and persons close to them?; What does the positive versus negative criticism concentrate on?; How does the reviewers comment the sexual element in the novels? The theoretical framework focuses on how womens literature has been treated in literary criticism and the treatment of the confession novels in the 1970s. The analysis of the reviews has, among many other things, showed that the novels mostly are regarded as something private; that the reviewers for different reasons question the publishing of the novels and that there are things concerning women and sexuality that is not accepted to write about.
Att leva med kroniskt obstruktiv lungsjukdom : En litteraturöversikt över patienters upplevelser
Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.
Det växer ju inte i magen men det växer i hjärtat : En kvalitativ studie om adoptivföräldrars erfarenheter av adoption
To investigate adoptions are part of the social worker's duties. The aim of our study was to examine some adoptive parents, to internationally adopted children, experience of adopting, the time before the adoption, the adoption process, and the time after the adoption. The study is based on qualitative interviews with seven adoptive parents. Theoretical frameworks that have been used are a phenomenological perspective, the dramaturgical perspective of Goffman and the theory of rites of passage.The result of our study shows that the adoptive parents have tried ?everything? to be-come parents in a biological way before they came to the decision to adopt.
Induktion av persisterande gulkropp hos sto : en framtida metod för att dämpa brunstrelaterade störningar?
This article starts with a review of the literature regarding the normal reproductive physiology of the mare, normal luteolysis, different causes of prolonged luteal phase and theories behind these. The article also presents a study where it was examined if treatment with human choriongonadotropic hormone (hCG) during the luteal phase induces prolonged luteal phase in mares, thus preventing estrus. The study consisted of two parts: one intensive study of eight mares at the former Department of Obstetrics and Gynaecology at SLU, Uppsala, Sweden and one field study of seven mares at a stud farm 70 km north of Uppsala. The mares in the intensive study were divided in two groups: one with four mares that were injected with hCG in luteal phase when they had a follicle of minimum 30 mm and a second group with four mares that were injected with sodium chloride at the same time. These mares were examined with ultrasonography and blood samples.
VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning
Coastal sediments are important carbon sinks, storing organic matter and thereby helping to
reduce the amount of greenhouse gases in the atmosphere. However, they can also act as
carbon sources if the deposited organic matter decomposes rapidly, contributing to increased
greenhouse gas emissions and global warming. Rapid decomposition partly depends on the
degradability of the material itself. In this literature review, I examine which coastal plant
species dominate different locations along the Swedish coast, based on coverage data from the
ClimScape project (www.climscape.se). For the most dominant species, I investigated the
type of organic matter they may contribute to the sediments and based on those results I
qualitatively assessed which sites that may function as carbon sinks or sources.
Utlakning av tungmetaller från Skörby deponi
The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.
