Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked. The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.

Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Hantering av extensivt hållna nötkreatur i mindre besättningar

Extensive cattle management was reintroduced in Sweden during the 1950´s and 60´s. Usually this term refers to suckler cows for meat production that is kept outdoors all year around. Suckler cow farms tend to become fewer but bigger over time. Still however most of the farms with beef cows are small. Extensive animal husbandry can lead to animals becoming shy which leads to difficulties when they are handled due to veterinary treatments, marking, transport etc.

Muntlig formativ kamratbedömning som kommunikativ praktik : En designbaserad studie i det naturvetenskapliga klassrummet

In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Den abstrakta tråkigheten : villkor och möjligheter, utifrån ungas perspektiv, att relevansgöra digitala medier som en resurs för lärande i skolan

Children and teenagers of today have grown up with digital media. According to Olle Findahl's report "The Swedes and the Internet" (2009), adults as well as children are online more and more. Our experience is that at many workplaces as good as everyone use computers and everyone is expected to have digital skills. However at most schools the reality is far from this. According to Findahl's report from 2009, 99 percent of all pupils (in Sweden) have access to computers and Internet, yet it is rare that they get school assignments where the use of Internet is acquired (Findahl 2009).The purpose of our paper is to understand how digital media can be used as a resource for learning, through the perspective of young people.

Trädgårdsstaden : från historisk idé till dagsaktuell verklighet

The aim of this study has been to make clear the conception of ?The Garden City?, and also to investigate why and how the garden city has come to be a more frequent and attractive form of settlement in our Swedish community. The essay is supported by a literature study about the garden city from its beginning (1890?s) to present time. To make a distinct explanation of the garden cities progress over time, I have studied the idea behind two garden cities of today, Tullinge and Vistabergs garden city.

Leaf structure and localization of a transgene protein in barley

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Vårdberoende, behov av omvårdnad och insatser för äldre med regelbunden vård och omsorg ? del av SNAC-Blekinge, Vårdsystemdelen

Background: The relationship between advanced age, presence of illness and impaired functioning is well known. A large proportion of the elderly population has an extensive need of care and service and therefore need help from municipal care. Aging is a transition in life and also affects the person's identity and self image, making the person particularly vulnerable and challenging everyday safety. It is therefore of importance to gain knowledge about which factors at individual and organizational level that support a person-centered nursing care for the elderly so that caring responsibilities and staffing of nursing personnel may be scheduled based on need. Aim: This study aimed at describing dependency and care needs of elderly persons living in ordinary housing, sheltered housing and nursing homes. Furthermore the study aimed at describing how the dependency was related to the staffing of non-licensed and licensed nursing staff in nursing homes. Method: A descriptive and analytical quantitative method was used in the study.

Internal Quality Audits as an Improvement Tool

A large proportion of businesses around the world is today ISO 9001 certified and is consequently conducting internal audits on a regular basis. It has however not been possible to conclude that internal audits always add value to the organisation, despite the large utilisation of this tool. Some authors, e.g. Alic & Rusjan (2010) and Wealleans (2000), mean that there are possibilities that internal audits may be used as a value-adding improvement tool. This has led to the emergence of this master?s thesis.The purpose of the case study was therefore formulated to examine how internal quality audits can be made more effective and used as an improvement tool.

Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.
