Är bor nödvändigt vid skogsgödsling i Sverige?

This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.

Karaktärisering av Gremmeniella-skadade bestånd inom Holmen Skog AB :

Since the end of the eighteenth century forest Damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

Canine S- and M/L- cone electroretinograms

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired Damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

Verbbenämning hos vuxna med afasi : Bedömt med Action Naming Test

Förmågan att benämna verb och substantiv kan skilja sig åt hos såväl friska vuxna (Strauss Hough, 2007) som personer med afasi (Mätzig, Druks, Masterson & Vigliocco, 2009). Hos personer med afasi har skillnader mellan förmågan att benämna substantiv och verb relaterats till skadelokalisation (Damasio & Tranel, 1993). Vid afasiutredningar används ofta benämningstest för att bedöma framplockningen av ord (Herbert, Hickin, Howard, Osborne & Best, 2008).Action Naming Test (ANT) är ett verbbenämningstest som normerats på svenska (Lindahl & Oskarsson, 2011; Stenberg & Wik, 2013), men inte studerats hos personer med afasi. Syftet med föreliggande studie är att undersöka hur verbbenämningsförmågan ser ut hos personer med afasi och expressiva svårigheter, i relation till den svenska normeringen för ANT. Några av orden i normeringen var problematiska, varför en reanalys av data genomfördes av Stenberg och Wik (2013).

Investeringar i småskalig vattenkraft vid befintliga dammar : - En studie av teknik-, ekonomi- och miljöfrågor

In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.

Identifiering av merva?rden i EPC-projekt

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Välfärd hos växande nötkreatur ? finns den?

During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.

Marknadsinriktad miljökommunikation på Internet : försäkringsbolaget Folksam

Many companies are presently investing in different types of environmental strategies, and it is varying to what level they channel their resources to environmental efforts. It is also diverging to what extent organizations effort to profile themselves as environmentally conscious. This can be due to difficulties in reaching out to customers and to finding the most efficient method of green marketing communication. The aim of this study is to analyse how an insurance company more actively can communicate environmental matters foremost in their contact with customers. One can in different mediums daily follow debates and discussions concerning the environment. Many insurance companies have also identified their role in performing green work.

Dynamisk analys och utmattningskontroll med hjälp av fältmätningar och FEM : Fallstudie över SL:s Bro norr om Söderströmsbron

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål

The purpose of this paper is to examine what problems cabbage growers have with the Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become a larger problem for cabbage growers in several countries in Europe as well as in Sweden. In Canada the problems are so severe that the midge is classified as a quarantine pest and therefore certain rules have to be followed. I have collected facts of the biology, host plants and reproduction of the Swede Midge, as well as the growers experiences and the occurrence of the midge in Canada, Europe and Sweden. The Swede Midge is hard to control because of its short life cycle and the larvae are protected between the heartleaves of the plant. When the larva feeds on the growth point the plant becomes distorted, in some cases several heads develop or none at all. When the midge infests spring rape its flower buds become undeveloped and rosette like.

Patienter med självskadebeteende - Deras upplevelser av sitt beteende och mötet med vården : Patients who self-mutilate - Their experiences of their behavior and nursing care

Bakgrund: Självskadebeteende startar ofta i tidiga tonåren men orsaken grundar sig i traumatiska upplevelser i barndomen. Beteendet är en medveten handling som utförs för att dämpa den psykiska smärtan och resulterar i en vävnadsskada. Patienterna anser sig ofta bli stigmatiserade och behandlade som objekt när de istället behöver känna stöd och förståelse från personalen i omvårdnaden. Syfte: Att belysa patienter med självskadebeteende, deras upplevelser av sitt beteende och av omvårdnadspersonalens förhållningssätt vid mötet i omvårdnaden. Metod: En litteraturstudie baserad på 11 vetenskapliga artiklar.

Upprepad administrering av trimetoprim/sulfadiazin till neonatala föl : plasmaproteinbindning och effekt på serumbilirubinkoncentrationen

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.
