En undersökning av ljus av ljus - den omvända skuggbildningen

This work is an exploration of a method and how to find balance between it and its contents. One part consists of a technical study on how to use UV light to yellow distinct surfaces on paper and the other is about how to find use of the method. The common denominator is determined as the consequence of the relationship between light and time. The result is three images that shows various traces of time with time as a graphic expression..

Hur påverkasogräsuppkomsten av jordbearbetning :

Today it is common to spray against most weeds by using very expensive weed-killers. The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers. Therefore it is in everyones interest to find other methods to fight the weeds. Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose. Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%. To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night. By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..

Effects of two different light programs on milk yield, prolactin, IGF-1 and sleep in dairy cows

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Hinder och möjligheter för arbetsmiljöarbete och rehabilitering i mikroföretag

The purpose of this study was to evaluate meals and eating in one day for at least ten truck or lorry drivers. Another aim was to investigate the attitudes by the drivers to food and meals and their expectations on the meals. This is a qualitative study conducted in ten interviews, seven of which were over the phone. The interviews were semi-structured and took about twenty minutes for each driver. Data relating to the food choices for one day were collected and questions asked about their attitudes to food and meals were collected simultaneously.

Lång dags färd mot natt och Natten är dagens mor : En komparativ studie och analys ur ett genusperspektiv

The aim of this paper is to compare and analyze Eugene O?Neill?s play Long Day?s Journey into Night with Lars Noréns Natten är dagens mor (Night is Mother to the Day). The gender and power structures, as well as the characters in the two plays are analyzed. The main focus of the analysis is on masculinities, and therefore on the brother to brother relationships in the dramas. The presence of ?queer leakage? (as defined by prof.

Light pollution : consequences and sustainable lighting design

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

Bright Chest of DrawersThis project derives from a fascination of spaces which withonly light and shadow withhold a narrative value, which createsemotions and experiences with a minimum of objects. Iwanted to invesitigate light and lighting, and create a productthat can change the mood and experience of a spatial enviromentwith light. Questions I asked myself was: How do I relateto the spatial limitations that arise? How can I, with light asmy tool, give form to an immaterial value or state of mind?Will the object that illuminates be the most important factorof communication and meaning when I want to tell a story, oris it the light itself?The result became a chest of drawers that is lighted up frominside when you open the drawers. It serves a function as a unitfor storage of objects, but also makes us reflect of the importanceof objects, of how we define a spatial enviroment, andwhat we consider as private spaces in our home..

Predation av sandräka (Crangon crangon) på juvenil piggvar (Psetta maxima) och juvenol skrubbskädda (Platichtys flesus) : betydelse av yngelstorlek för överlevnad hos piggvar och skrubbskädda efter bottenfällning

Turbot (Psetta maxima) and flounder (Platichthys flesus) are two species of flatfish both having their nursery areas around the shores of Gotland in the Baltic Sea. The common brown shrimp (Crangon crangon) is a known predator on newly settled plaice (Pleuronectes platessa) in the North Sea area and is also found in the Baltic Sea. Experiments were carried out to see if the brown shrimp is predating on juvenile turbot and flounder, and if so on which sizes, and if the brown shrimp prefers any of the flatfish species, and also to see if there is a difference between day and night in density of the shrimp, i.e. when the fish might be subjected to predation. The results showed that predation decreased with size for both turbot and flounder.

A graphical mapping of how light is used in theatre

This treatise analysis what functions light has in theater. It was inspired by Rosalinda Krauss essay Sculpture in the Expanded Field but builds mostly on the following three books Linda Essig Lighting and the design idea (2nd ed), Nigel H. Morgan Stage lighting for theater designers and Francis Reid The stage lighting handbook (6th ed). It discovers nine unique functions of light (performance style, dramatic style, image,illumination, 3D space, 3D form, selectivity, environment, atmosphere) and develops a graphical mapping of them based on a mapping by Reid. The functions performance style, dramatic style, image are superior the others.

O Mistress mine   : En dramateoretisk analys av tematiken kärlek och musik i William Shakespeares Twelfth Night eller What You Will

I uppsatsen behandlas William Shakespeares komedi Twelfth Night. Dramat publicerades för första gången 1623 och innehåller, på samma sätt som många av hans tidigare komedier, motiv som förväxlingar och sökandet efter en sann kärlek. Intrigen bygger på att människor på grund av en förklädnad inte känner igen varandra. I det här fallet är det en ung kvinna, Viola som får omgivningen att tro att hon är man.   Shakespeares Twelfth Night är uppbyggd genom en komposition av olika teman och jag har undersökt hur han har motiverat sina motiv kärlek och musik och genom dessa skapat dramats lyckliga slut.
