Vilka stöd finns det för elever med ADHD i skolan? : What forms of support are available at school for pupils with ADHD?
Syftet med denna studie har varit att undersöka vilka stöd det finns för barn med ADHD i skolan. Studien bygger på intervjuer med två klasslärare, en speciallärare, två rektorer samt en observation av en elev med diagnosen ADHD. Skolorna i undersökningen har varit en kommunal f-5 skola samt en f-9 friskola. För att belysa detta ämne ur en ny synvinkel har jag valt att undersöka lärarnas erfarenheter av sambanden mellan språkutveckling och ADHD. Intervjuerna visar att lärarna underströk att barn är olika och att man därför måste arbeta utifrån den enskilde individen.
Smärtlindring hos killingar efter avhorning :
The main purpose of this study was to investigate the effects of the non steroidal anti-inflammatory drug (NSAID) meloxicam in connection with dehorning of goat kids. Six 2-3,5 weeks old dehorned kids were given daily intramuscular injections of meloxicam (0,5 mg/kg; MG) and five age-matched dehorned kids were given isotonic NaCl (NG) for 3 days. The study was randomized and double blinded. The behavior of the kids was studied one day before dehorning, on the dehorning day and three days after. Blood samples were collected each day before the treatment and analyzed for plasma concentrations of meloxicam, hematocrit, cortisol, progesterone and glucose.
Synoptisk provtagning i vattendrag med eutrofieringsproblem : En studie för att identifiera områden för prioritering av åtgärder
In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.
Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län
Burnt alun shale and lime is the residual product that was formed when alun shale was
used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium,
molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this
paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale
and lime to determine whether or not the surrounding environment and humans are
exposed to these elements by eating plant products.
A cultivation trial was carried out where onion, carrot, and lettuce were grown on three
mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments
were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a
reference soil. The reference plots were natural soil mixed with peat adjacent to the
mounds.
Improvement of positive strand assay used in detecting positive and negative RNA of hepatitis E virus
Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).
Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser
Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.
Exponeringsrisker i samband med inhalationsbehandling av häst :
Bronchiolitis is a common performance decreasing disease in horses (Bracher et al,
1991¸Dixon et al, 1995) Its medical treatment includes inhalation therapy with
corticosteroids and b2-adrenoceptorer stimulators. Use of both these medicines is
prohibited for sport horses and athletes. Because the facemasks used for inhalation
therapy are not airtight, there is a risk for leakage of these medicines. We wanted to
see if cross exposure of nearby horses can result during normal recommended
treatment of a horse, and assess if this could result in doping positive urine sample
from the person treating the horse and from horses in the same airspace.
We did a pilot study with four healthy horses. The experiment was divided into
four parts.
Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam
Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.
Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen
Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.
Att delta och förändra, trots kaos! - En studie om Försäkringskassans organisationsförändringar.
Earlier the regional social insurance office was exposed to critisism because of bad administration and a lack of providing public service. Among other things the regional social insurance office was attacked because of long investigation hours and indinstinct working methods and was blamed for not being able to solve the unhealth in the society. This lead to the reformation of the previous regional social insurance office into a government authority agency on the first of Januari, 2005. Extensive organizational changes were made so that regional social insurance office could handle the demands and become a uniform public administration. I have made a qualitative study where the purpose was to se how the changes affected the public administrators and I focused on their participation and willingness to change.
Metodbeskrivning för identifikation av råvaror med TLC
In some cases there are no methods to identify raw material which are included in dietary supplements such as tablets. The identification can be done with TLC. A general method description was developed using the raw material gotukola and appel cider vinegar. This includes processing to achieve higher concentration of the active ingredient if needed; evaluation of solubility agents to dissolve the active substance; evaluation of mobile and stationary phase and visualization of the stationary phase. The report also includes an evaluation of stationary plates..
Hur kan jag veta det när det inte står i texten? : Läsförståelse bland gymnasieelever med neuropsykiatriska funktionsnedsättningar
Studies show that some pupils with ASD (autism spectrum disorder) can have difficulties in understanding written texts. The present study seeks to examine whether pupils with ASD differ in their reading comprehension of a factual text and a literary text. Another aim of the study is to obtain a picture of the reading habits of high school pupils with ASD, what reading strategies they use, and how they work with texts in Swedish lessons in school.The study uses texts from PISA surveys from 2009 and 2000. The factual text Varmluftsballongen (The Hot-air Balloon) was taken from the try-out for the 2009 survey and the literary text Gåvan (The Gift) was taken from the 2000 PISA survey. To gain some idea of the pupils? reading comprehension of the texts, the present study used the tasks accompanying the texts, with certain changes in the questions about the text on the hot-air balloon.
Drankgivans och vallfoderkvaliténs effekt på konsumtion och produktion hos mjölkkor :
The coproduct, dried distillers grains + solubles (DDGS) from ethanol production based on wheat contains much rumen degradable protein and fiber with low digestibility. To compliment this quality in an effective way a grass silage low in protein and much digestible fiber is needed.
The aim of the study was to investigate the effects of adjusting the crude-protein concentration and fiber quality of the silage when feeding DDGS and of varying the
inclusion level of DDGS, when feeding the adjusted grass silage, on intake, milk yield and composition, faecal traits and feed efficiency.
Four different total mixed rations were compared. The normal grass-clover silage had a crude protein content of 17,8 % and an NDF content of 46,2 % of dry matter. The adapted grass silage had a crude protein content of 14,6 % and an NDF content of 52,9 % of dry matter. The diets were formulated to have similar nutritional content except for A + 4 which had a higher content of rumen degradable crude protein and a lower concentration of NDF.

Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota
The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.
