Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Arkeologihund : En studie i experimentell arkeologi om möjligheten att använda hund som arkeologisk prospekteringsmetod för att lokalisera humanosteologiskt material.
In today?s archaeology there?s a growing need for non-invasive prospection methods. However there?s a methodological gap and what?s missing is a method for locating human bones. In this study a specially trained German shepherd is put through scientific tests determining how good the dog is at telling the different between the scent of human and animal bones.
Sjuksköterskors upplevelser av hot och våld inom akutsjukvård
Background: An indisputable right for nurses is to have a safe and secure work environment so they can deliver a high quality care. To bring a clear definition of what threat and violence are, is an important part in the work to prevent threat and violence. One part of the problem is that the experience and understanding of threat and violence can be different from one person to another. Aim: The aim of this quality study was to emphasize Nurses experience of threat and violence at workplace. Method: The method used in this study was qualitative interviews in the sense to bring out the nurses experience.
Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?
After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.
Trygghetskänslan hos mammor som går på tidig hemgång efter förlossningen
Vårdtiden för mammor efter förlossningen har minskat markant de sista decennierna. Det är därför av vikt att undersöka hur nyblivna mammor upplever den första tiden efter de har fött barn. Syftet med studien var att undersöka känslan av trygghet som mammor, med tidig hemgång, kände under den första veckan efter förlossningen. Metod: Enkäten Parents Postnatal Sense of Security (PPSS) med 18 frågor plus tre tilläggsfrågor användes. Enkäten skickades till 100 nyförlösta svensktalande mammor med normala förlossningar och tidigt hemgång.
Utmattningssyndrom och KASAM. En möjlighet till en ökad känsla av sammanhang?
Some people who recovered from exhaustion disorder report that their lives feel more meaningful after the disease than before, despite residual symptoms and difficulties. This experience of increased meaningfulness has been linked to sense of coherence, SOC. The research question was whether individuals with exhaustion disorder at onset has a weak SOC, and if there is a general increase towards a higher SOC value ??during the recovery process. In a cross-sectional study, data were gathered on the SOC value via the SOC 29 form.
Demokratins gränser. Ett liberalt alternativ till påverkanprincipen
What every theory of democracy has in common is a reference to ?a people? who are, in one way or another, collectively self-governing. Given that, surprisingly little attention has been paid to the so called boundary problem of democratic theory, or, in other words, the question of who should be included in the democratic community. Lately, the historically given boundaries have been questioned in favour of a cosmopolitan democracy. Still, little has been said about the boundary problem in general, especially from a theoretical point of view.
Hormonstörande ämnen och deras effekt på barns hälsa : - Hur ser kunskapen ut hos småbarnsföräldrar?
Endocrine disruptive chemicals (EDCs) are found in many everyday products and can cause adverse effects on human health. Small children are particularly sensitive to EDCs and they are also exposed to them in a greater extent than adults. Despite this, EDCs are only banned in a few toys and childcare products. There are many sources of exposure and if no steps are taken to reduce the incidence of EDCs we may face an increasing number of people diagnosed with obesity, diabetes type 2 or various types of cancer.The Swedish Government has set a number of environmental objectives, one of which is calleda non-toxic environment. The Swedish Chemicals Agency was instructed to produce and conduct a national action plan to achieve this goal.
Screening av dysfagi på äldreboenden i Linköpings kommun
Changes in swallowing function are common in elderly and chronically ill individuals. Therefore it is important to be aware of these changes and their prevalence. The aim of this study was to assess the prevalence of dysphagia in nursing homes in the municipality of Linköping, and to correlate dysphagia with variables that can be a cause or a consequence of dysphagia. These variables were gender, age, MMT-result, dentition, weight loss, medical diagnose or number of medications. The intention was also to examine the additional information regarding dysphagia supplied by pulse oximetry.Sixty nursing home residents aged 74-101 years were chosen to participate in the study.
Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?
Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water.
The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission.
The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed.
Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed.
As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting).
The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture.
Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied
with 0.8 L per week.
Kartläggning och visualisering av riggkonstruktionsprocessen : Fallstudie från Scania
Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.
Rabies : en utmaning för Indien
This literature study describes the ways in which the spread of rabies can be prevented in India, what guidelines are set and also which methods have proved most effective.
Every year rabies causes the death of around 20 000 people in India, which makes the prevalence in the country the highest in the world. The main source for human infection is bite wounds from infected dogs. People and animals can be vaccinated both prophylactic and post-exposure prophylactic (PEP), despite this the disease continues to claim high number of victims. The majority of those dying are young men and children from the poorer part of the population. Knowledge among the Indian population on rabies and its transmission routes, wound care and vaccinations is very limited.
Förstudie för skapandet av ett miljöövervakningsprogram : en styrkeanalys angående vattendrag i västerhavets vattendistrikt för fastställandet av provantal i tid och rum för ett effektivt omdrevsprogram
The environmental monitoring in Sweden has been developed by several different parties and is now being coordinated and made more effective in order to meet the current demands on high quality information regarding the state of the environment. Sweden has been divided into five different water districts based on watershed areas because of requirements in the Water Directive of the EU. In Sweden there are two common types of environmental monitoring programs used to gather information on changes in time and in space. Currently both these two types are used for lakes in the water district of the western sea but only one is used for watersheds.
The purpose of this report is to supply basic information regarding the possible need for a second environmental monitoring program for watersheds in order to better describe the spatial variation within the district as well as to determine the number of samples necessary in order to describe the district over time and space.
"Aspergers syndrom är jag" En kvalitativ studie om hur det kan vara att leva med Aspergers syndrom
Asperger´s syndrome is a state with certain difficulties in social relations, communication and perception. People with Asperger´s syndrome often have a special interest for a certain topic. The main purpose of this study was to describe how grown people with Asperger´s syndrome make sense of living with Asperger´s syndrome. The inquiry was based on semi-structured interviews with eight persons with Asperger´s syndrome. We reached those subjects trough interest organisations for people with Asperger´s syndrome.
Den svenska regeringens förvirrade klimatarbete
The aim of this study is to clarify the Swedish government?s purpose of participating in theEuropean Union Emission Trading Scheme. Taking as its departure point state-centricinternational political economy this study presents three plausible hypotheses on what thepurpose might be. Either it is to promote consumers interests, or to promote the Swedishnational climate goal ?Reduced impact on climate?, or to promote the profit of Swedishcompanies.
