Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropGrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Teknik för vårskörd av hampa till stråbränsle :

Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive Growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops. The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.

Debaser : en "ångvält" på Stockholms livemusikscen

Syftet med uppsatsen är att göra en deskriptiv studie av drivkrafter bakom Debasers uppkomst och utveckling på Stockholms livemusikscen samt försöka identifiera dominerande idéer på fältet som kan ha påverkat Debaser och livemusikscenens utveckling. Med fält syftar vi på fältet för musikbranschen. Inom fältet ryms bland andra olika aktörer på livemusikscenen, boknings- och skivbolag, musiker och kulturpolitiker.Uppsatsen är en kvalitativ studie som till stor del baseras på primärdata från intervjuer med Debasers grundare och med personer inom fältet för musikbranschen. Vid intervjuerna har vi utgått ifrån en semistrukturerad intervjuguide som tar upp vissa teman och förslag på specifika frågor baserade på syftet och den givna referensramen för studien. Referensramen består av teorier inom det institutionella perspektivet, organisationsidentitet, entreprenörskap och tillväxt.De slutsatser som vi kommit fram till är bland annat att Debasers uppkomst till stor del möjliggjordes av tre dominerande idéer inom fältet som kommit att påverka Stockholms livemusikscen.

Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?

Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.

Stadsodling : möjligheter och begränsningar

Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.

Hormonell påverkan vid uppkomst och utveckling av juvertumörer hos hund

Under puberteten börjar hundens juver att utvecklas. Detta kräver närvaro av ett flertal olika hormoner, exempelvis östrogen, progesteron, prolaktin och tillväxthormon (GH). Men även tillväxtfaktorer så som insulinlik tillväxtfaktor 1 (IGF-1) och epidermal Growth factor (EGF) krävs. Samma hormoner och tillväxtfaktorer kan leda till juverhyperplasi och medföra en ökad risk för juvertumörer. Juvertumörer är en av de vanligaste tumörtyperna hos tikar och representerar ungefär 70 % av alla cancerfall. Den typiska patientbilden är en äldre, okastrerad tik eller en tik som blivit kastrerad senare i livet.

Welcome to Stockholm? : En studie om destinationsmarknadsföring och exportmognad

An increasing global tourism offers great opportunities for Sweden as a tourist destination. However, an attractive destination requires competitive destination marketing strategies. Tourist destinations often include a complex network of stakeholders of small and large en-terprises that represent both the public and private sector. One condition for successful des-tination marketing is that all of these stakeholders collaborate in their marketing to create an integrated and powerful image. Another important aspect in terms of increasing the des-tinations competitiveness is that the local tourist companies are "export-oriented", in order to ensure that international tourists are looked after appropriately.This study has focused on the destination marketing of Stockholm.

Utveckla eller avveckla : varför väljer vissa av Milkos medlemmar att utveckla sin mjölkproduktion medan andra avvecklar?

The Swedish dairy sector is facing several challenges the coming years. One big challenge is how they will secure the access of their raw material milk in the future. The number of milk producers has decreased for an extended period of time, but was for a long time partly compensated by an increased productivity among the remaining milk producers. From year 2000 that trend was broken and also the quantity of milk produced started to fall quickly. Milko is a dairy company with members from Dalsland in the south to Jämtland in the north. During the first seven moths 2007, their number of members decreased by almost a fourth, from 1 272 to 974.

Svenska investerares risktolerans : En studie om risktolerans och påverkande faktorer

The Swedish household?s savings has increased the last couple of years, according to Statistiska centralbyrån. But the amount of households that trades on the stock market has decreased from the year 2012 to 2013. The diminished interest in stock trading carries a risk by leading to a smaller yield for the private savers, and also effect the business development and the economic Growth. High brokerage fees will aggravate the ability to attract venture capital.

Hörby kommun i förändring : utveckling för framtiden

We live in an exciting society, characterized by continuous changes and challenges. The effects of the globalization are widespread. The continuous flow of people, capital and goods follows in the wake of advances in communications, transport and information technology, resulting in a changed situation for different stakeholders in the society. This situation leads to increased cooperation and exchange, but also increased competition. The primary means of collecting empirical data for this study was interviews and a document study.

Managementperspektiv på grisproduktion i Lojsta :

At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership! This degree thesis is meant to answer the question about which the optimal extension would be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.

"Anders Andersson hade eld i sin tjärdal" : en analys av Jonas Åströms dagböcker 1868-1891

"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891 Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.

Globaliseringens påverkan på den svenska tillväxten : En studie av åren 1980 till 2050

Sverige är ett av världens mest globaliserade länder och globalisering känns därmed som en självklarhet i dagens samhälle. Att något är en självklarhet behöver dock inte betyda att det är bra, varför det finns anledning till att undersöka vilken effekt globaliseringen egentligen har haft och kan komma att få på den svenska välfärden. Eftersom välfärd ofta mäts som tillväxt i BNP är det också detta mått som används i denna uppsats.  Syftet med denna uppsats är tudelat där den första delen består av att ta fram en modell inne­fattande faktorer av globalisering, som förklarar Sveriges BNP-utveckling mellan åren 1980 och 2008. Den andra delen av syftet är att, genom användande av den framtagna modellen, analysera hur globalisering har påverkat och kan komma att påverka den svenska BNP-tillväxten fram till år 2050.Studiens metod består av en teoretisk och en empirisk del. Det teoretiska momentet utgörs av en litteraturstudie i dels globalisering och dels tillväxt vilken mynnar ut i en Solow-modell med humankapital som är utvidgad med faktorer av globalisering.

Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or Growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
