Klassificeringssystem för basmateriel vid F 21
Norrbottens flygflottilj F 21, men även hela flygvapnet, har i dagsläget problem med kontrollen över den basmateriel som brukas där. Med basmateriel avses all utrustning som används vid verksamheten på en militär flygplats och omfattar allt från kokvagnar och personbilar till momentnycklar och bogserstänger för flygplan. En stor del av denna materiel har antingen överskridit underhållsintervallet eller utsatt tid för modifiering. Ett sätt att återfå kontrollen är att göra en kvalitetsöversyn för att fastställa hur stor del av denna överskridna basmateriel som på något sätt påverkar luftvärdigheten. Syftet med examensarbetet har varit att åt F 21 ta fram ett klassificeringssystem som skiljer ut den basmateriel som är luftvärdighetspåverkande från den övriga.
Konstruktion av beslag med dörrfunktion till spridarlucka
This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.
Alternativ till fiskbaserat foder till karnivora fiskar
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
Alkohol till min nästa? Hur nattvardens gemenskapsmotiv i möte med Lögstrups etik, skulle kunna motivera ett alkoholfritt nattvardsvin i Svenska kyrkan
How the Eucharist?s motive of communion in combination with Lögstrup?s ethics could motivate a non-alcoholic sacramental wine in the Church of Sweden.The purpose of this essay is to illuminate the meeting between the person who gives out bread and wine in the Eucharist and the person who receives the wine, from tree perspectives: the communion in the Eucharist, the ethical demand of K.E. Lögstrup, and today?s knowledge of alcohol and it?s negative effects on the human being. I want to study how these three perspectives can affect the interpersonal meeting in the Eucharist when it comes to giving out alcoholic wine, and to investigate if Lögstrups ethical demand could be used by the Church of Sweden when to decide about a sacramental wine with or without alcohol.I have started to study K.E Lögstrup and his theory about the ethical demand, and then researched the Eucharist in the Church of Sweden and the results of recent sociological and medical research of alcohol?s effect on the individual and on society.
Sker rengöring av ögon, antenner och mun hos Odonata : Coenagrion larver med hjälp av borsten på framben och fötter?
Dragonflies are fascinating. The larvae stays larvae from a couple of weeks up to 5 years, it depends on the species (Hansen, 1981). The temperature, nourishment and time of the year also play a role for the growing factor for the larvae. Both Sahlén (1985) and Begon a.o (1990) say so. My report contains information about the branched setae on the front legs from the family damselflies (Zygoptera) and the species Coenagrion.
Goliatmusseron (Tricholoma matsutake) - kräver den en kontinuitet av träd? :
Modern forestry management may disadvantage some mykorrhiza forming fungi because; they are dependent on late successions and cannot survive the constantly recurring breaks in the continuity of their host tree. For this study the specie goliatmusseron (Tricholoma matsutake) was chosen to investigate this possibility. In Sweden T. matsutake is found in greatest amounts north of Örnsköldsvik on glacifluvial sandy soils in association with pine trees and reindeer lichens.
Seventy two forest stands where the specie previously had been found were studied; 62 in the northern part of Sweden and ten in the southern. Several indicators were studied to find out if these stands have had a continuity of living trees.
Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
Ekjättars framtid : en fallstudie av gammelekar idag och i framtiden vid olika skötsel- och restaureringsscenarier i Hjulstaområdet, Enköpings kommun
This Master's thesis work was done at SLU, Uppsala, Sweden in cooperation with Upplandsstiftelsen and Uppsala County Council. The studied area is pointed out as an area for EU´s LIFE project, NATURA 2000, concerning the Scarabid beetle Osmoderma eremita. The studied area lies in an agricultural landscape rich on deciduous trees, about 15 km south of Enköping in the County of Uppland. The species is dependent on large, old, hollow trees, which are exposed to sunlight, usually oak trees in this area. I studied the area in detail concerning large old trees (>70cm ø), middle-aged oak trees and young oak trees.
De blir fria i tanken : En kvalitativ studie om pedagogers tankar om pedagogisk dokumentation
This MA thesis analyzes how the protagonists and the narrative structure relates to ?the Child? as a linguistic/cultural construction in Mare Kandre?s early authorship (1984-1991). A thematic of children portraits defines this period of Kandre?s writing, which consits of the following works: In a Different Country (1984), The Annunciation (1986), Bübin?s Kid (1987), The Burning Tree (1988) and Aliide, Aliide (1991).Linguistic components, such as the word ?child?, the name ?Kid? and a reconstruction of the concept of childhood, holds an actuate position in these narratives when they first appear in direct relation to the protagonists. This suggests how generally accepted categories and concepts consciously are at work in Kandre?s writings.
Tidsstudie av containerhuggbil
The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.
Lähäckar för minskad vinderosion och andra ekosystemtjänster
Människans näringar och kulturer har orsakat landskapsförändringar som på många håll i världen lett till flera ekologiska konsekvenser som erosion liksom övergödning av vattendrag och hav. Skogsbruk såväl som jordbruk har därutöver resulterat i stora utarmningar av den
biologiska mångfalden på jorden. Sedan en tid har jordbrukets negativa konsekvenser fått alltmer uppmärksamhet inom bland annat politik, forskning och näringsliv, varav somliga människor aktivt försökt stoppa det negativa händelseförloppet som manifesterat många av
världens odlingslandskap. Diskussioner som innefattar ekosystemet och dess så kallade tjänster för människans såväl som andra organismers överlevnad och välbefinnande erhåller därutöver mer och mer fokus i strävan mot miljövänligare alternativ för storskalig odling. I
sökandet efter mer ekologiskt sunda odlingssystem har intresset igen väckts för agroforestrysystem, som kombinerar vedartade växter med vanligt förekommande grödor.
Etableringen av lähäckar på respektive intill odlingarealer i Skåne kan bidra med flertalet ekosysystemtjänster vilka bevisats stoppa ex.
Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner

Mortalitet av bok i Biskopstorp och Frodeparken naturreservat, Halland :
The aim with this study was to investigate mortality in older respectively younger beech
stands (Fagus sylvatica), the different types of dead wood in the forest and the availability of coarse woody debris (CWD). The research was carried out in previously managed and seminatural stands in Biskopstorp and Frodeparken, located north of Halinstad in Halland,Sweden. Data were collected from 22 stands with at least 50 % beech and with a minimum age of 5 1 years, ranging in size from 0,67 to 19,9 ha. A transect was placed in each stand, in which the diaineter on both dead and living trees with a minimum diameter of 50 mm was recorded. On seven to 13 dead trees, depending on the size of each stand, decomposition stage, primary and secondary cause of death, amount of fungi and the type of the dead wood was noted.
Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence
The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.
