Barkar det åt skogen för svenskt tidningspapper? : empirisk analys av efterfrågan och företagsstrategier på den svenska marknaden

According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.

Kundlojalitet : Kundnöjdhet och kundlojalitet i researrangörsbranschen

The primary purpose of this thesis is to investigate the operation of membership criteria, which are applied against countries that wish to join the European Union (EU). More specifically, the importance of some criteria in comparison to others is considered. To answer this proposal, three questions are posed: What are the EU membership criteria? Are some criteria more important than other criteria? Does the EU treat candidate countries differently in applying the membership criteria? Three countries are used in this analysis, each country representing one recent enlargement round: Poland (2004), Romania (2007), and current candidate country Turkey. Both official documents, such as EU treaties, and unofficial documents such as statements from EU leaders are used to analyze the application of membership criteria.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

Familj eller karriär i arbetslivet, måste man välja? : -en uppsats om arbetstagares skydd mot diskriminering i arbetslivet.

Pregnant workers are considered at risk in the labor market and therefore need extra protection from employment discrimination . The purpose of this essay is to investigate what protection of pregnant workers against discrimination in employment situations and  if  there  is  no  corresponding  protection  for  female  workers  claim  the  right  to parental leave.The essay describes the national and EU rules on applications and practice, showing how pregnant women and workers on parental leave are treated in the labor market. Through Sweden's accession to the EU , we must apply the requirements nationally EU imposes on its member countries.The essay shows that pregnant employees have a strong legal protection from discrimination in employment , from both DL and by EU directives . Employers who deny workers employment because of pregnancy is guilty of direct discrimination on grounds of sex, because it is only women who may become pregnant. It is not important whether it is a temporary or permanent position .

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :

Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization. It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared. During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.

Minskad trädtillväxt under Lilla sitiden? : En dendroklimatologisk jämförelse mellan nutid och 1600-talet invid trädgränsen i norra Skandinavien

During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate,  a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.

En nation av emigranter: En studie över den salvadoranska statens förhållande till sin emigrerande befolkning samt konsekvenserna för deras medborgarskap.

Around the world governments reach out to their emigrant population, embracingthem as part of the nation, expecting their economic contribution. The aim of thisthesis is to examine the political strategy and governmental activities of ElSalvador with the purpose to include emigrants in the nation building project. Themain question is what consequences this has for the significance of citizenship.This case study is based on the theoretical framework of external citizenshipwhich is a new fenomena emanating from states growing interest of theirexpanding diaspora. It divides external citizenship in two parts; a legal dimensionand a practiced identity.I find that as the economic potential of salvadoreans abroad increase, theSalvadorean government makes institutional changes to tie emigrants to thenationstate. This results in the possibility for salvadoreans to remain citizens intheir country of origin, practicing their salvadorean identity at the same time asthey naturalize abroad.

Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat

Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

Framställningar av svenskhet i media : - En diskursanalys av tidningsartiklar om invandring och integration

The media plays a key role in constructing identities and categories, as its messages influence the way we understand the world. In the debate on integration issues, categories such as ?Swede? and ?immigrant? are often treated as obvious and unproblematic. ?Swedish?, being the norm, is seldom defined   and   frequently appears   with   subtlety.   This   paper   set   out   to   study   what   characterizes Swedishness in newspaper articles on integration issues, and how it is represented in relations to immigrants.

Mödrars upplevelse av stöd vid amningsstarten

IntroductionStatistics show a declining trend despite the many benefits of breastfeeding.AimThe aim was to investigate how new mothers experienced the care associated with childbirth, with focus on breastfeeding.MethodThe study included mothers who gave birth in a hospital in the middle region of Sweden during 2011, and who responded to an online survey (n?1000). The present study was based upon answers from the open questions concerning dissatisfaction and suggestions for improvement and have been categorized using content analysis.ResultsMothers described failure in several areas, with a negative impact on breastfeeding. Many experienced that they had not been seen and treated like an individual, and that the healthcare staff had been unpleasant, impersonal, ignorant and stressed. Mothers wanted more credit from the staff concerning their own ability and some reported that they had been controlled and ?run over?.

Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Behandling av lakvatten med kemiska oxidationsmedel för att delvis bryta ned oönskade organiska förening : en studie utförd vid Hovgårdens avfallsanläggning i Uppsala

A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. The oxidants investigated are Fenton's reagent, hydrogen peroxide, Oxypro, potassium permanganate and potassium persulfate. The study was made on untreated leachate and leachate that has been treated in an aerated dam followed by sedimentation dams collected from the Hovgården landfill, and alson on sludge water from sludge storage cells. The effects of the five oxidants have been established by analysing the UV absorbance at the wavelengths 253,7 nm and 260,0 nm at different pH values. The UV absorbance was used to indicate the amount of aromatic hydrocarbons in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent.

Skattekonsekvenser av generationsskiften i fåmansföretag : -En analys av befintliga regler

A change of generations occurs several times during a company?s lifetime. It is a process that requires planning and time. If the current owner wants to keep the company within the family, he has two options; he can either sell the company to a family member, or give the company to the new owner, like a gift. When the owner sells the company, it is common that he accomplishes it to a losing price.

Miljöbedömning av olika behandlingsmetoder för organiskt hushållsavfall, slakteriavfall och flytgödsel

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

Fuktproblematik i platta på mark : En analys av uppkomsten till fuktproblem

When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
