Aerosolers dygnsvariationer och långväga transporter
This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..
Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment
This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
En studie av landskapsindex för kvantifiering av rumsliga landskapsmönster
Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om dess storleksberoende inkluderas eller ej. Utvärderingen körs för ett landskap på cirka 50 km2, men även för tre mindre områden i landskapet: åkerbygd, mellanbygd samt skogs-bygd. Samtliga områden jämförs sedan i två olika skalor, flygbild respektive satellitbild..
Bredspridning av grönmassa :
There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.
Val av område och områdesskydd för Natura 2000 med skogshabitat : En jämförande studie av fyra län i Sverige
The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.
Barns behov av pappa och av skydd från våld : Diskurser inom verksamheterna Barn- och ungdomspsykiatrin (BUP) och kvinnojourer i form av skyddade boenden
This qualitative study aimed to examine which discourses can be found within the Child and Adolescent Psychiatry (BUP) and women?s shelters against domestic violence, concerning children that have experienced violence within the family, from two perspectives: the child?s need of father and of protection from violence. The study also aimed to examine which discourses can be found within the organisations concerning children?s well-being, how they define their mission concerning domestic violence and how this can affect the practical work with children that have experienced violence and their parents. The questions that the study aimed to answer were which discourses can be distinguished within BUP and the women?s shelters against domestic violence and how they can affect the different agencies? view of the child?s need and well-being.
36 § avtalslagen mot oskäliga ansvarsfriskrivningar i kommersiella avtal : En komparativ studie med Common Law
In claims for unfair dismissal due to alleged redundancy, the burden of proof should be shared to enable an employee to have the cause of redundancy tried. In such a case, the employee should present evidence of an invalid cause ? such as personal reasons ? and the employer should account for the redundancy. With reference to their conflicting interests, the law favours the employer if the redundancy can be accounted for even if the employee maintains his or her position. This would have been reasonable practice if the employer?s evidence was subject to the same scrutiny as that of the employee but, as long as redundancy is considered a valid cause in itself, this is not the case.Redundancy does not come from nowhere, but it occurs when employers carry out their management decisions.
UV-tork - analys av drift :
The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.
Till för medmänniskan Om medmänsklighet utifrån Martin Buber och Gustaf Wingren
This is a study of humanity about the meetings we have with one another. I write about this subject out of the perspective of Martin Buber and Gustaf Wingren. As I enter this area and begin the writing a few questions are being developed, such as:? Why do we as humans have the need to meet each other?? ?What happens with us when the meeting is absent?? ?What does it mean to love your fellow man or woman?? ?What helps or destroys our possibilities to meet each other?? Buber talks about Me and You and the aim of the meeting we have with each other. When we meet each other it generates a responsibility against each other.
En studie om möjligheter att stoppa förfalskningar : Spårbarheten i en global värld
The purpose of this study is to describe the traceability of products that protect against counterfeiting and examine how protection against counterfeit products have been developed to date, and to display the opportunity to streamline the protection of products and brands.Nowadays, in the global world, it is getting increasingly more difficult to track the products. Especially for the last link in the chain, which in most cases is the customer and who is constantly exposed to risks. This report deals with the possibilities of preventing and detecting counterfeit products. Fake products are not unusual in an historical perspective. It has been common with counterfeits ever since the Middle Ages continuously until today. Forgers have become more skillful and they are successful in most industries. Many of the fake products are of poor quality and can be downright dangerous to the customer.To answer the question, the author used a qualitative collection method.
Svenska kattägares inställning till vaccination

And the choice of the camp site depend on the security and the service that the camp site offered. The camp site was controlled and the campers controlled each other.
Moder Jord i kyrkorummet? : En undersökning av kopplingarna mellan det kristna och det fornnordiska i Vester Egede kyrkans dopfunt som objekt och vad angår motivval, tolkning och dopritual.
A church in rural Vester Egede from the earliest Christian period in Denmark e.g. the early 1100, a baptismal font is found showing a woman breastfeeding two animals. She is said to be a typical early roman Luxuria, in mild appearance. However, what makes her unique is that she appears standing on the top of her head, her womb serving as font. The main question is how come that a baptismal font like this is to be found in a church, leading to the sub question, if this font really has a Christian origin or could it be rooted in Norse, pre-Christian tradition, alternatively is the font an expression of a syncretism between the two colliding cultures.
