Hög fyllnadsgrad i timmerlagret : en fallstudie av Holmen Timbers sågverk i Braviken
Holmen Timber har byggt ett nytt sågverk i Braviken, utanför Norrköping. Målsättningen är att såga 1 100 000 m3fub per år, i sågad form 550 000 m3SV (SV=sågad vara), till år 2013. För att utvärdera olika timmerplanslösningar har simuleringsverktyget Simsaw utvecklats. Med hjälp av programmet kan timmerflödet av ankommande timmer fram till sågen simuleras och dess effekter utvärderas.Syftet med studien är att analysera utfallet av olika timmerplanskonstruktioner, där vältors antal och längder förändras för att hitta en lösning som skapar en hög fyllnadsgrad av timmerlagret. Vilket i sin tur kan skapa ett bra underlag för sågen att såga långa sågserier med få ompostningar som positiv följd.
Kvinnliga virkesköpare inom Holmen Skog
Holmen Skog has only five out of 70 wood buyers who are women, This report is seen as a step in the process towards gender balance in the company. This is a problem that is equal over the entire forest industry in Sweden. They all think that sexual equal workplaces are very important to remain competitive, see things from different perspectives and development of the company.
The survey was done by sending out questionnaires to all women who work and have worked as a wood buyer at Holmen, and as many men of both categories. These four categories became a total of twenty persons. To map the industry another questionnaire was sent out to the six largest forest companies in Sweden.
The survey found that female wood buyers not finished their work earlier than men did, as they thought before.
Effect of insoluble fibre enrichment on egg quality in laying hens
Studien var en del i ett större projekt som syftade till att undersöka hur värphöns påverkas beteendemässigt och nutritionellt av ökad konsumtion av olöslig fiber. I det nu aktuella projektet undersöktes hur ökat intag av olöslig fiber påverkar äggkvalitén. Fiberkällan utgjordes av halmpellets som antingen blandades i fodret med 3 % inblandning, alternativt utgjorde strömaterial för att undersöka strömaterialets betydelse som fiberkälla. Två olika hybrider ingick i försöket, 720 Lohmann Selected Leghorn (LSL) och 720 Lohmann Brown (LB), varav halva antalet av varje hybrid hölls i frigående system och andra hälften i inredda burar. Totalt insamlades och undersöktes 180 ägg från varje inhysningssystem då hönorna var 31-32 veckor gamla.
Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :
According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.
Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet
Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.
Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark
In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
Delat ledarskap, en gemensam resa
Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

sågverk
Bollsta sågverk ingår i SCA Timber och är ett furusågverk. Under 2006 producerades det 410 000 m3 sågade trävaror. Syftet och målet med arbetet är att kartlägga och på kort tid öka tillgängligheten för hela såganläggningen. Den ackumulerade målnivån på 77 m3/timme ska höjas till 82 m3/timme av sågad vara. Det finns en potential för hela anläggningen om ströläggaren förbättras.
Arbetssätt kring värdeflödesanalys för tillverkning av marina båtmotorer på Volvo Penta
Volvo Penta has been producing boat engines since 1907 and are world leading in this segment. They have today an extended range and also sell industrial power stations. Quality, safety and environmental care are three core values for Volvo and together they strive to give their customers the right product with the right quality.Volvo has developed a production system named Volvo Production System, VPS, and one of the pillars is continuous improvements. Within this pillar you can find value stream mapping, which is used to analyze the value stream through the process. This tool gives a wide perspective and helps to keep focus on the entire process instead of just parts of it.Volvo Penta in Vara has earlier done value stream mapping but without good results since they didn?t take set-up times and imbalances in account.
Omvårdnadsdokumentation : granskning av omvårdnadsjournaler inom psykiatrisk slutenvård
Background Swedish nurses are required by law to document nursing care. Studies have proved scarce in nursing documentation with regard to written language, the nursing process and the nurse´s caring perspective. Educating nurses in using the VIPS model have improved nursing documentation. Few studies have included nursing documentation of psychiatric care.Aim The aim of this study was to describe nursing documentation within psychiatric care of inpatient settings.Method A quantitative, retrospective descriptive research design was applied. A total of 60 nursing journals from a psychiatric department of six wards were studied.
Att bli värdigt bemött : En tvärsnittstudie om bemötande på akutvårdsavdelningar ur patientens perspektiv
Previous research and patient complaints to the Swedish Patient Support Committee shows that there is a lack of substance in the patient-nurse relationship. This may suggest that it can be difficult for health care to live up to health-care law which requires it to be of good quality, based on dignity and respect and designed so that the patient is an active participant and can make their own decisions when it comes to their health care. For a better understanding of what a dignified patient-nurse relationship is, this study aims to clarify what the patient values as good patient-nurse relationship and describe how they have experienced the patient-nurse relationship during their stay at an emergency care department. The study is a descriptive cross-sectional study with a quantitative approach, where the population consisted of patients who were cared for at an emergency care department in the County of Västmanland, Sweden during 2007. The sample consisted of 93 patients which were asked to answer a questionnaire.
Svenskt Sigills kvalitetssäkring av spannmål :
Today there is a limited demand for quality certified cereal in Sweden. The demand can in the future increase and become a requirement for the entire market. Since the first of January 2005, grain producers in Sweden are food producers and traceability is important for the food industry. It is possible for grain producers to certify the productions under the certification IP SIGILL. The purpose of this essay is to explore why some grain producers continue to be certified while other producers end the IP SIGILL certification.
Påverkan från den förväntade klimatförändringen på tillväxten i norra Sveriges skogar : En litteraturanalys
This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.
Validation of Steins/Arla Foods method for lactate fermenting clostridia in milk
One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.
Utva?rderingsmodeller vid offentlig upphandling : En granskning av fo?rekommande modeller och mo?jlighet till ett enhetligt val av en modell
Syftet med studien var att behandla utvärderingsfasen inom offentliga upphandlingar och mer specifikt från ett leverantörsperspektiv. Offentliga upphandlingar utförs för att få bra kvalitet till ett lågt pris. De kan utföras genom lägsta pris eller ekonomiskt mest fördelaktiga anbud. Genom begärda avslutade upphandlingar kunde modeller som använts identifieras ända ner till dess korresponderande matematiska modell. Poängvägningsmodeller anses inte konsistenta på grund av att de påverkas av irrelevanta variabler likaså den relativa kvalitetsvärderingsmodellen i teorin.
