Forestry supply chains : preparing for the unpredictable
Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms.
This thesis bases on previous work on supply chain mapping and cost theories.
Bentiska evertebraters förekomst i källor på Öland
Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Kartering av skogsskador hos bok och ek i södra Sverige med hjälp av satellitdata
Populärvetenskaplig sammanfattning: Kan satellitbilder användas för att studera skador på bok och ek?Sedan mitten av 1970-talet har man sett ökande skador på skogen i stora delar av Europa. Olika storlek på skadorna och att storleken på skadorna skiljer sig åt beroende på var man befinner sig har gjort det svårt att förklara orsaken. För att undersöka ifall skadorna även ökat i Sverige har Skogsstyrelsen utfört inventeringar på bok- och ekbestånd i södra Sverige under tre tillfällen; 1988, 1993 och 1999. Resultatet från undersökningen visar att konditionen hos bok och ek i södra Sverige har försämrats sedan den första inventeringen 1988.
Miljödammars funktion som kväve- och fosforfälla samt som bevattningsdamm i Sölvesborgs kommun
A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.
Värdeflödesanalys som verktyg för effektivare byggproduktion: Studie över köksproduktionen
Rapporten består av en studie över köksproduktionen på ett stort svenskt bostadsföretag i Sverige. Studien är utförd med hjälp av verktyget värdeflödesanalys som är avsett för att hitta slöserier i en process. Processen som undersöks består av mottagning och inbärning av köken till lägenheterna samt hela montaget, i fyra olika projekt. Varje leverans är uppdelad i tre kök åt gången som kommer var fjärde dag. Denna leveranstakt är även den takttid som gäller för köksproduktionen, d.v.s.
Underlag för en kommande rivning av J-huset på Akademiska sjukhuset i Uppsala : Generell planeringshjälp vid utförande av rivning
This report is about planning a demolition. The purpose of this report is that it should become a base for a demolition of house J at the Academic hospital in Uppsala, and also to make general help for planning a demolition. This report also contains a part about how a change in the work environment affects general people. The work started with studies of literature and design of the general part of the report and then continued with a practical study of house J. From the experience of the first two parts of the report a general help for planning a demolition was shaped.
Återföring av växtnäringsämnen från avloppsvatten till åkermark : en bedömning av intresset för nya näringsrika produkter
Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers.
In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.
Environmental, Social and Governance : Hot eller möjlighet för investerare
This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index. In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in comparison to non- SRI adjusted companies..
Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion
Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

According to the researchers it isimportant that the children and young people become involved and dedicated to theenvironment and its surrounding world. It is important to listen to the children's thoughts andvisions as they are aware about what happens, but do not reflect on the worst, but hope that itbecomes an improvement in the future.
Vingårdar i Sverige! : farligt för miljön?
The future climate of Sweden is expected to become warmer in the future. This would be beneficial for vineyards and may lead to a greater area being allocated for wine production. The environmental impact concerning eutrophication from Swedish vineyards has not been evaluated before. In this study nutrient balances are constructed for four Swedish vineyards with the goal to estimate the out and in flows of nutrient in the systems for the year 2010. Interviews with focus on farming practices undertaken during the year are conducted with the farmers.

Today, there are environmental certifications for the food industry, the forestry, the fisheries sector and several more. In apparel industry, certification for sustainable working conditions has been of major impact. The property sector is no exception from other industries.
Investerares önskemål om CSR-information i företags hållbarhetsredovisningar
To act responsible in relation to environmental, economic and social issues is a trend that is spreading among businesses and their investors. In order to assess business risks, ethical interested investors are calling for open, honest, clear CSR information that can be followed up in corporate sustainability reports. The ability to communicate about risks and to meet investors requests already in the business analytic process can save resources and increase the company?s profitability.The idea that companies should take responsibility for their impact on society from economic, environmental and social perspective is called Corporate Social Responsibility, CSR. In addition to CSR, there is another three-letter abbreviation in this context, PRI ? Principles for Responsible Investment ? which are principles, signed by ethically interested investors.
