"Inne" är att vara ute? : Användandet av utomhuspedagogik i tio mellansvenska skolor
Gotland is famous around the world for its unique nature. The agriculture here has always been an important source of income and part of the identity of the island. But today the profession has low status and hard to survive. How can the interest for farming be increased?Gotlandsgården is an investigation about how the agriculture could develop.
Automatisk detektering av skillnader av Androidenhetersanvändargränssnitt
Android-applikationers användargränssnitt kan se annorlunda ut på olika Android-enheteroch det är svårt att anpassa en applikation efter alla enheter då det finns så många unikamodeller. Målet med arbetet var att framställa ett verktyg som kunde med hjälp av ett korrektdefinierat gränssnitt, upptäcka skillnader i gränssnittet mellan olika Android-enheter.Ett egenutvecklat verktyg framställdes och hade en hög precision. Verktyget kunde bådaupptäcka skillnader och rapportera hur stor skillnaden var mellan gränssnitten..
Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser
Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.
Hästskor, hästskosöm och sporrar från Västergarn : en empirisk studie av hästrelaterat material från seminarieutgrävningarna 2005-2012
Västergarn is one of the smallest parishes on the island of Gotland. It?s a place of rich history and has been subject to numerous excavations throughout the years. The University of Gotland has conducted seminar excavations at Västergarn between the years of 2005-2012. During these excavations a lot of horse related finds have been found.
Ändamålsanpassad TINA-sortering av sågtimmer :
Swedish sawmills of today suffer from unsatisfying economy with high costs and low
benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner.
Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way
gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are
mainly manual but can in some rare cases be automatic.
Vilken effekt har lärkrutor på ogräsfloran vid ekologisk höstveteodling? :
This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping.
Studies in England have shown that skylark reproduction can be greatly improved within
conventional fields, at a low cost, by establishing patches of bare ground (skylark plots).
Within conventional farming, herbicides can be used in case a weed problem arises due to
implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers.
The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.
Demand and perception of fertilizer : among small-holder farmers in Kenya
Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.
Global Price Management ? Incentives for Implementing an IT-based Price Management System
Problem discussion: Syncron experience a challenge in realizing the full market potential of its newly developed IT-based price management system, Global Price Management (GPM). The system has already been implemented and is currently running with success within the IT-structures of the first customer. The fact that the development of the system has been initiated by a customer, and thereby has left Syncron oblivious of the real underlying drivers and incentives for the development, is part of the problem. Understanding the customers? incentives for developing their pricing process thus reducing the application uncertainty is a good starting point.
Bosättning, agrarkris och fäbodväsende : vegetations- och markanvändningshistoria i Läde, Dalarna
By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming.
The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.
Utvärdering av skördekartering under flera år på samma fält
I denna studie har jag tittat närmare på värdena för rådata i skörd av spannmål, genom att
utvärdera skördekartering från tre olika fält, två fält på Sannarps egendom och ett fält på
Nya Fjällalunda gård. Gårdarna ligger i Halland utanför Falkenberg och Sannarp AB står
för driften av båda enheterna. De skördekarterade grödor som ingår i studien är foderkorn,
rågvete samt höstvete. Studien har gått till på det viset att i de tre fälten har två provytor
belägna nära en markarteringspunkt valts ut. I provytorna har rådata lästs ut från
skördedata och sedan jämförts med medelvärdet för fältet.
Andlig växtodling, historiesyn och kunskapsteori - hur hänger dessa begrepp ihop? : en översikt av fyra odlingspraktikers ideologier.
Abstract
Spiritual gardening, historical perspective and epistemology,
- how do these concepts connect? A review of the ideologies of four pragmatic growers.
The purpose of this thesis is:
? to present an alternative forthcoming perspective on knowledge, that may be of
significance for future theories and knowledge about growing and gardening.
? to lift experiences with Nature Spirits into an academic context, that permits us a closer look at the phenomenon.
? to contribute to an academic platform connecting humanistic and natural sciences.
The intention of this text is to bridge the differences between the strictly rational traditions of knowledge and those more experience based ones. The thesis wants to show that much
can be won if feeling based and mental reflections once again are approached as equal
sources of knowledge. The aim is to give an orientation about the subject of Nature Spirits.
The interesting fact is not whether (that) one can talk to nature, but how one does it and that
more can be understood about nature and the reality that the established sciences study.
The form for this study of literature is a describing presentation; to put names on and give
wording to the phenomena of Nature Spirits and Plantdevas. The sources of literature are
four pragmatic practitioners of spiritual gardening who have written extensively about their
own work.
Hackelselängden beroende av skördemetod :
The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.
Stridsyxor eller båtyxor : En diskussion om symboliken och dess betydelse
My intention with this paper is to try to understand the meaning of the double sex symbols which can be identified on a number of Neolithic so called battle axes from the region round the lake Mälaren in Sweden. My conclusions are drawn after having studied a number of archaeological thesises. I have realized that the society was egalitarian from what is said about the funeral habits since women and men were buried with the same care. Ceramics from the Skogsmossen site show a very long continuity over 15-20 generations. These facts indicate a peaceful society without traumatic breaks where knowledge would have been lost.
Plantinventering och plantkontroll med digitala bilder från helikopter :
This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.
Från soptipp till naturreservat : En studie av makt i Lövsta-Kyrkhamn-Riddersvik genom actor-network theory
This paper investigates, through an actor-network theory perspective, how the recreation area Lo?vsta-Kyrkhamn-Riddersvik northwest of Stockholm has developed from being a dumping site into becoming a nature reserve. This investigation also tries to describe and explain which values that have been promoted in the area by the local voluntary associations and companies. Lo?vsta-Kyrkhamn-Riddersvik has been inhabited for more than 3000 years, originally with farming as the most important business.
