Akvaponik beskrivs som en innovation som kan fr?mja h?llbar livsmedelsproduktion, samtidigt som dess implementering ?nnu inte har n?tt kommersiell framg?ng. Tidigare forskning identifierar flera hinder f?r en etablering av systemet i olika delar av v?rlden, men situationen i Sverige ?r mestadels outforskad. Denna studie unders?ker vad som hindrar kommersiell akvaponik i Sverige utifr?n ekonomiska, regelm?ssiga, sociala och milj?m?ssiga aspekter, samt hur dessa hinder kan motverkas.

I januari 2011 delades de tva? sista fria IPv4-adressblocken ut av Internet Assigned Numbers Authority (IANA) till den asiatiska Internetregistratorn Apnic (Asia Pacific Network Information Centre). Detta inneba?r att adresserna som fanns i den centrala adresspoolen nu a?r slut. Registratorn hade anso?kt om dessa adressblock eftersom det ra?der akut brist pa? Internet Protocol version 4- (IPv4-adresser) i Asien samtidigt som Internetanva?ndarna i denna del av va?rlden o?kar explosionsartat (Magnusson, 2011a).

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

Bakgrund och problem: Digital transformation ?r ett hett ?mne inom aff?rsv?rlden, med ett ?kande antal f?retag som str?var efter att anpassa sig till digitala teknologier f?r att f?rb?ttra sina aff?rsmodeller och skapa nya v?rdeskapande aktiviteter. Men med digitala transformationen kommer ocks? utmaningar som budgetber?kningar och brist p? teknisk kunskap vilket ofta leder till misslyckade transformationer. St?rre f?retag har ofta mer resurser till att hantera dessa utmaningar j?mf?rt med SMF.

Background: Female representation on boards is an ongoing debate. The European Parliament voted in November 2013 in favour of a proposal that it should be at least 40 percent women on company boards by 2020. Jens Spendrup, president of the Confederation of Swedish Enterprise, was interviewed on Swedish Radio in February 2014 and stated that there are not enough qualified women to recruit to the company boards. The listed companies in Sweden only have 22 percent of women in their company boards and given Jens Spendrup?s statement should they have difficulty reaching up to 40 percent by 2020.

Bakgrund: Tidigare studier visar att postoperativ sm?rta f?rblir underbehandlad, trots att 80% av alla patienter upplever en m?ttlig till sv?r sm?rta efter operation. Studier visar ?ven att sjuksk?terskors kunskap g?llande sm?rta ?r otillr?cklig och att sjuksk?terskornas egna v?rderingar kommer in i sm?rtbed?mningen, vilket p?verkar den sm?rtlindring som patienterna erh?ller. Syfte: Denna studie syftar till att unders?ka vilka m?jligheter och sv?righeter sjuksk?terskor p? en kirurgisk v?rdavdelning har i att bed?ma och hantera patienters postoperativa sm?rta. Metod: Tre semistrukturerade fokusgruppsintervjuer utf?rdes, d?r sammanlagt nio sjuksk?terskor deltog. Dataanalysen genomf?rdes med Graneheim och Lundmans (2004) kvalitativa inneh?llsanalys. Resultat: I resultatet framkom tv? huvudkategorier, den f?rsta var ?Utf?rande av sm?rtbed?mning? och det framkom att sjuksk?terskorna anv?nder NRS framf?r andra skattningsinstrument d? det ans?gs vara den snabbaste metoden och gav goda m?jligheter att bed?ma sm?rtan.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.

Tre intervjuer utfo?rdes pa? undersko?terskor pa? gruppboende, demensboende och hemtja?nst. Dessa erbjuder en inblick i den praktiska verksamheten.Resultat: Fo?ljande faktorer av betydelse fo?r att fo?rebygga eller motverka dehydrering identifierades samsta?mmigt i litteratur och vid intervjuer: (1) kunskap om den a?ldre via dokumentation, (2) anpassning av tillva?gaga?ngssa?tt vid servering av dryck efter den a?ldres preferenser och tillsta?nd, (3) hemtrevlig miljo? med sociala interaktioner, (4) bedo?mning av va?tskeintag, va?skebalans och riskfaktorer via uppma?rksamhet, va?tskeregistrering och med hja?lp av flera andra yrkesgrupper samt med ha?nsyn till den a?ldres historik, (5) pa?minnelser (sa?rskilt vid demens) och en stor ma?ngd la?ttabsorberade drycker som intas succesivt vid diarre? och kra?kningar, (6) la?ttanva?nda och specialutformade hja?lpmedel.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

Parametrar som hja?rtfrekvens och blodtryck kan pa?verkas av musiken.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

Thereto examine the parameters that affect the flanges motion during the manufacturing process. The goal was to provide Volvo Aero with foundation to later bring in slimmed forgings.

Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.
