On the hunt for improvements : possibilities of increasing welfare in captive cheetahs through hunting enrichment
The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala
Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.
Kattungens behov och rådgivning till dess ägare
The cat has become a popular pet. To secure a prosperous cat-human relationship, the cat owner has to understand what kind of animal the cat is and what requirements need to be fulfilled. The purpose of this literature review is to summarize kittens? needs of socialization, anthelmintics, nutrition, vaccination and gonadectomy, until the age of six months and to give the cat owner information on how to care for the cat during this period. Articles were search for in ScienceDirect, Primo and Scopus.
Strategier på en dynamisk marknad - en analys av skånska gardencenters och handelsträdgårdar :
Garden center and market gardens are a growing trade, undergoing great changes with new
actors and purchasing habits. The interest in gardens and plants is steadily increasing, official
statistics show an increase of garden plants and flower consumption, of an annual 3 per cent.
Garden centers and market gardens are in great need of development to be able to tackle the
prevailing competition, and maintain a steady growth. Many companies are heading for a
generation shift and are founding it difficult to find and employ younger managers. The aim
of this report is to examine different strategies of garden centers and market gardens through
the manager/ owner?s views and opinions about competition, growth and success.
Dekoration av plasttallrikar
A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.
Evaluation of tools for analysis and quantification of Fusarium mycotoxins
Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.
Påverkas stereotypt vandrande hos amurleopard (Panthera pardus orientalis) vid ökad förutsägbarhet i samband med utfodring?
Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.

Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?
The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.

In 2008, 35% of theworld's population were overweight and 11% obese , which is almost doubling since 1980,according to WHO. Recommendations on overweight and obesity is not just about what weeat but how we eat. A generally accepted recommendation is to eat slowly and chew yourfood properly in order to increase fullness and reduce energy intake.
Vildsvinsskador inom jordbruket : hur stora är förlusterna?
Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.
Förutsättningar för virkesinriktad skogsodling med inhemska trädslag i Peru : en studie baserad på handelsstatistik för tropiskt timmer och fyra efterfrågade arters skötselkrav
Det finns arealer med degenererad skogsmark i tropikerna som kan vara en potential för att bedriva skogsodling och möta framtida efterfrågan av förnyelsebara resurser. Med detta kandidatarbete avsågs att undersöka globala avsättningsmöjligheter för tropiskt lövträvirke och identifiera ett antal inhemska lövträdslag lämpliga för skogsodling på tidigare avverkad och degenererad mark i Peru.
Med data från International Tropical Timber Organization (ITTO) och Food and Agricultural Organization (FAO) sammanställdes global produktion och export av tropiska lövträvaror. Därefter identifierades via en litteraturstudie ett bruttourval av kommersiellt gångbara och/eller vanliga inhemska lövträdslag lämpliga för skogsodling i Peru. Fyra av dessa trädslag valdes ut för en närmare beskrivning beträffande deras odlingsegenskaper.
Den globala produktionen av tropiskat lövträvaror ökade med ca 21% under perioden 1995-2012, samtidigt minskade den globala exporten under perioden 1990-2012.
Pallhantering på Findus - Flöden , problematik och alternativ
The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.
