Används ekonomiska planeringshjälpmedel i lantbruksföretag : beslutsunderlag med hjälp av kalkylmetoder
In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers.
This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment.
The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.
VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.
Vem är det som kör egentligen? : maskinanvändande och könsroller inom lantbruket : en intervjustudie med kvinnliga lantbrukare
In this report female farmers use of technical equipment is investigated. There is little research made on this subject in Sweden, therefore this report can be seen as an explorative study. Research makes it clear that machinery, throughout history and even today, has been seen as a male area. Heavy machines are often associated with the same attributes as masculinity. Force, power, efficiency and control are some examples.
Livscykelkostnader för vindkraft : En jämförelse av fallstudier
I denna rapport har det utförts två fallstudier från två olika vindkraftsanläggningar och med hjälp av en utarbetad modell har livscykelkostnaderna jämförts för de två fallstudierna.Resultatet visade att livscykelkostnaden per producerad kWh sjunker allteftersom den installerade effekten blir högre.Kostnadsmodellen som utarbetats och tillämpats för resultaten har visat sig ha hög verifierbarhet då resultaten har varit jämförbara med litterära studier..
Vad är verklig kostnad per koplats? :
Purpose
There are almost infinite numbers of ways to build dairy farms in Sweden. When building a new free stall barn you have the possibility to affect both working environment and animal welfare for many years to come. The construction costs are influenced by which type of barn that is built and what functions it contains, for example one can predict that automatic milking systems are more expensive to integrate than milking parlours. But what is the real cost of today for the construction of free stall barns with milking centres and how is it affected by construction methods and functions? Is the labour time influenced by the building costs? These are some of the questions this report will try to answer.
Teknik för egen foderberedning :
There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding.
When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level.
We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.
Havsöringens (Salmo trutta) lekvandring i Själsöån, Gotland.
In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.
Hur kredithandläggare lantbruk i sina kreditgivningsstrategier beaktar den potentiella riskfaktorn att säkerheten i form av åkermark faller i värde
The increase in farmland value in Swedens plain areas is a well known fact in today's Swedish agricultural. In connection with the fluctuating prices of crops and inputs, are increasing the risk exposure to agriculture. The increased value of agricultural land has in Sweden over the years been due to a high demand for land that has existed and exists in Sweden. The increasing demand is linked to a structural rationalization of Swedish agriculture, leading to fewer and larger farm units (www, privataaffärer, Carl Johan Jurss).The purpose of this study is to examine the potential risks associated with the farmland value falls or remains unchanged, according to a farm credit administrator's perspective. The idea is to get a picture of the main factors taken into account when lending and the problems with falling or stable land prices into account when lending.
Järnåldersboplatser och historiska byar : En studie av agrara bebyggelsemönster i mälarbygder under 1500 år
Following paper deals with the questions about prehistorian and medieval settlements in the Mälar Valley and their relations to the historically known hamlets or single farmsteads from the 17th- and 18th-century cadastral maps. Models over settlement development through the period A.D 200 to 1700 done by geographers Ulf Sporrong and Dan Carlsson are tested and compared to the knowledge won by recent archaeological excavations. Is there a connection between the older settlements linked together by dry-stone walls and the late Iron Age settlements? Does the picture differ from the one presented for the Gotland region? How well are the general theories about different settlement development depending on basic natural conditions as for the potentials for cultivation and topography, corresponding to the physical remains? Are there other factors involved when the settlement structure takes its form?The methods that are used here constitutes mainly of a comparison between different locations in the Mälar Valley that has got a well known prehistory thanks to extensive archaeological excavations. Cadastral maps, soilmaps, topography maps and maps over ancient monuments are intertwined to the same map and analyzed through works in Geographical information systems.The results of this study reveal an interesting suspicion in the continuity-question through the Iron Age.
HUR KAN VI REDUCERA DEN INTERNA ÖVERGÖDNINGEN SAMT REGLERA ALGBLOMNINGAR FRÅN ATT NÅ EGENTLIGAÖSTERSJÖNS KUSTZON ?? : En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.
The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..
Konstruktion av maskin för Tillverkning av sågblad
The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.
Seroprevalence of Toxoplasma gondii and Neospora spp. in equids from three municipalities in Pará, Brazil
This study presents a survey of the seroprevalence of Toxoplasma gondii and Neospora spp. in equids in three municipalities in Pará, a Brazilian state with the Amazonian rainforest and the Amazon River as dominating features. Toxoplasma gondii and Neospora spp. are two closely related parasitic protozoans not separated as different genera until 1988. Neospora spp.
Blandfoder i automatiska mjölkningssystem
A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way.
The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.
Londonpolisen och kravaller från 1985-2011 : En studie i glömskans dynamik
Genom historien har människor runt om i världen stått upp mot ett beteende de har ansett vara orättvist. Det har förkroppsligats i strejker, kravaller och rentutav revolutioner och statskupper. Lika länge har ordningsmakt, men även politiker, behövt hantera dessa typer av samhällsuppror. Syftet med denna studie är att, utifrån ett policyorienterat perspektiv, undersöka vilka lärdomar Londonpolisen drog av kriser under tidsperioden 1985-2011. Vidare ska det undersökas vad som hände med dessa lärdomar när den brittiska inrikespolitiska agendan förändrades. Det intressanta ligger i att undersöka vilka lärdomar som kan dras och huruvida sådana lärdomar kan bestå utan underhåll från den politiska sidan och när frågorna på agendan förändras.
Djurhållning och hälsoproblem i svenska mjölkgetbesättningar : sett ur djurägarperspektiv
Very little is known about the health situation amongs Swedish dairy goats. The population of Swedish dairy goats can only be estimated, and that number is somewhere .
