The economic consequences of Striga hermonthica in maize production in Western Kenya

Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.

Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Du är vad du konsumerar ? En studie om ekologisk konsumtion

Den rådande klimatsituationen utgör, på grund av föroreningar i naturen, ett hot mot jordens fortlevnad, det kan främst påvisas genom de klimatförändringar som blir allt mer tydliga i världen. Samhällets negativa påverkan på jordens klimat sätter press på samhällsaktörer, varav en av dem är handelssektorn. Livsmedelsbranschen är den aktör som idag arbetar mest med ansvarsfullt företagande. Fokus läggs främst på ekologiska produkter, miljömärkningar samt energieffektivt arbete.Trots satsningar på ekologiska livsmedelsalternativ samt egna märkesvaror med ekologisk inriktning råder idag kunskapsbrist bland konsumenter. Den finansiella aspekten utgör, tillsammans med tid- och bekvämlighetsaspekter, de huvudsakliga påverkansfaktorerna på konsumenters medvetna och omedvetna beteende.

Justifying high price with Total Cost of Ownership awerness - possible or not on the Asian market?

Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: First a descriptive approach will be taken, identifying FP Ltd?s employers? perception on how to meet the customer. This will later be compared to our empirical findings of the actual customer behaviour in Thailand and Vietnam. Thorough analyse of the gap between the two parts will give us the outcome whether or not FP Ltd will have any use of presenting a quantitative model justifying their higher price.

När religion och djurskydd kolliderar : slakt utan bedövning

The fact that animals have feelings is something that is commonly agreed. Many authors showhow animals' views of their environment is quite similar with human views. Animals, whichare slaughtered without prior stunning, find the moment of slaughter unpleasant and stressing.This is shown in numerous of scientific studies. The cognitive ability of animals can becompared to how they experience feelings and scientists have shown how the structures in thebrain that involves feelings and cognitive behaviours in animals are very much the same asthe structures in human brains. Because of this, some scientists consider that behaviour inanimals can be directly interpreted into human feelings.Halal- and kosher slaughter comes from traditions.

Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Måltiden; näring för gemenskap : En kvalitativ studie kring den äldres upplevelser av måltidssituationen på ett särskilt boende.

The aim of our study was to examine how the elderly experience their meal situation in a sheltered housing. We have used a qualitative approach. We conducted individual interviews with six elderly in a sheltered housing to collect our empirical material. To reach the purpose of this study we tried to answer the questions: which factors affect the elderly person?s experience of the meal and which significance does the meal have for the elderly? To reach deeper understanding for our collected material we used Maslow?s theory of human motivation, the two concepts of Tönnies; gemeinschaft and gesellschaft, disengagement theory and the concept of Bourdieu, called habitus.

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

Fröodling av Raj- och rörsvingel i Sverige

Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.

Betesdrift vid automatisk mjölkning i ekologisk produktion :

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

Optimering och effektivisering av biogasprocessen vid biogasanläggningen Kungsängens gård

Under år 2008 användes globalt en energimängd motsvarande nästan 144 000 TWh ochav dessa stod fossila bränslen för 81 %. I Sverige uppgick energitillförseln under år2010 till totalt 616 TWh och av detta stod råolja/oljeprodukter för 30,4 %. Vidförbränning av fossila bränslen frigörs koldioxid, en gas som bidrar till att förstärkaväxthuseffekten. År 2000 uppmättes halten av koldioxid i atmosfären till 370 ppmv ochför att den globala temperaturen inte ska öka med mer än 2°C bör halten stanna på 450ppmv innan år 2100. Ett sätt att minska andelen av fossila bränslen är att öka andelen avförnybara energikällor, som t.ex.

Skolmåltidspersonalens upplevelser av att kunna påverka måltidssituationen

Övervikt och fetma är ett av de mest omfattande folkhälsoproblemen i Sverige och det är en stor andel barn och unga som lever med detta problem. Då goda matvanor grundläggs i tidig ålder utgör skolmåltiden en betydelsefull roll för att upprätta hälsosamma matvanor. Faktorer i den fysiska matmiljön, såsom möblering, städning, dekorering, inredning, belysning samt ljudnivå påverkar elevernas upplevelse av måltidssituationen. Den psykiska miljön som innefattar både psykologiska och sociala faktorer, det vill säga servering av skolmaten, arbetskläder, matglädje, elevernas matintag samt möjligheterna för skolmåltidspersonalen att gå någon fortbildning är även av betydelse för måltidssituationen. Dessa faktorer har studerats i detta examensarbete som utförts på uppdrag av Region Halland och som syftade till att studera skolmåltidspersonalens upplevelser av att påverka måltidssituationen i skolan.

Utfodring av sällskapskanin. Vilka råd ger vi djurägarna?

The most suitable method to answer the issues of this study was to do a combined literature- and questionnaire study. The literature part of the study was based on Original Research articles, Review Articles and books with a list of reference literature after each chapter and the purpose was to answer the questions ?What feed items should be given to rabbits in different life stages? and ?Which problems may develop from an inadequate diet?? Two questionnaires were constructed. One was sent by e-mail to small animal veterinary hospitals to be answered anonymously by veterinary nurses. The other was linked to from two internet forums, that with rabbits as their focus.
