Differences in host plant preferences and olfactory physiology between populations of the moth Spodoptera littoralis established in Egypt and Benin

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

Hur skiljer sig investeringsbedömningen mellan kommunala och privata fastighetsbolag?

This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.

FN:s barnkonvention : Demokratins positiva inverkan på staters implementering av barnkonventionen. Fallet Nigeria.

Even though many states have ratified the UN Convention on the Rights of the Child and sworn to protect human rights, viloations occur every day both in developed and developing countries. United Nations gave Sweden critique for not implementing the Convention conrerning article 11, which raises the question how respected the Convention is amongst other states? Does democracy contribute to a higher level of implementation?.

Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Skapandet av morgondagens lärare : En komparativ analys av två lärarutbildningars introduktionskurser

This study intends to analyze and compare the core litterature outlined in two specially selected teacher training establishments. The purpose of the investigation is to examine what specific perspectives they focus upon and the competences they require for teachers of tomorrow.The result shows that there are certain differences in perspective when varying the point of focus, but there are also common elements inte the core litterature between the two establishments. This analysis will provide a base for discussion on how the differences may be a result of the environment where the colleges of higher learning are situated and also on the individual needs in the surrounding area when they were first established..

Betygsskillnader på Kallingeskolan : - ett attitydsproblem?

It?s not a new occurrence that girls have higher grades than boys. Statistics show the same at the Kallinge school in Ronneby. There is a great difference between boys and girls in their grades from the ninth class. There are many different factors that affect the pupils.

Perceptuell och akustisk bedo?mning av ro?stfunktion hos barn med tonsillhypertrofi : Effekter av kirurgi

In Sweden over 10.000 patients annually, mostly children, undergo tonsillar surgery. The most common surgical method is total removal of the tonsil, tonsillectomy (TE). During the last decade partial tonsil resection, tonsillotomy (TT), has been reintroduced and is associated with lower primary morbidity and less postoperative pain. The aim of the present study was to evaluate if and to what extent 4-5 year old children?s voice function are affected by tonsillar hypertrophy compared to controls and to study the effects of the two surgical techniques on vocal function.

En Projektgrupps lärande

Vårt syfte med denna uppsats är att bidra till en ökad förståelse för hur lärande sker inom en projektgrupp och vilka sociala och organisatoriska konsekvenser lärandet får för arbetet. Vi har sett att olika sorters lärande uppstår i olika situationer och dessa leder till varierande former av kunskap. Kunskap värderas olika beroende på de antaganden som styr organisationen och högre värderad kunskap tenderar att uppmärksammas mer än annan kunskap. Relationer är en förutsättning för lärande och hur dessa uppstår och förändras beror på tre faktorer vi sett; trygghet, status och tid. Dessa tre faktorer påverkar i sin tur arbetetsuppgifter och arbetsfördelning i gruppen på olika sätt..

Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Betyg som allmän handling

Syftet med den här kandidatuppsatsen har varit att studera vilken legal status tentamen och tentamensvar samt elev- och studentbetyg har i svensk rättstillämpning med hjälp av frågorna är tentamen och tentamensvar allmänna handlingar samt är elev- och studentbetyg allmänna handlingar? I uppsatsen har den traditionella juridiska metoden tillämpats. Utredningen visar att tentamen samt tentamensvaren av Kammarrätten i Stockholm definierats som offentliga allmänna handlingar först efter att tentamen slutförts, eftersom de omfattas av provsekretess. Av de rättsfall som redovisats i uppsatsen kan konstateras att betygsdokument de facto är allmänna handlingar. För friskolor gäller dock att betygen blir allmänna handlingar först när betygen når kommunen..

Optimalt mottagningsstall för kalvar : en fältstudie

A cattle producer that buys calves that are younger than six months to the herd should have a starter stable to prevent infection spreading in the herd. According to the Swedish animal welfare regulation there has to be a starter stable if more than 50 calves that are younger than four months are bought in yearly to the herd. The aim of the study was to improve the knowledge about bovine buildings and management of starter stables to obtain optimal weight gain and health of the calves. The hypothesis 1) The younger the calves are when purchased, the higher the calf mortality and 2) Purchasing calves from a high number of herds involves a higher risk of calf health problems and calf mortality were tested in the study. The objective of the study was to give advices by way of presenting ideal solutions of how a starter stable should be constructed and managed. A field study was done during June to September 2008 to collect knowledge and experience from existing starter stables.

Bitch eller bög: en studie av ungdomars syn på kvinnligt och manligt

Denna uppsats behandlar ungdomars syn på manliga och kvinnliga egenskaper ur ett jämställdhetsperspektiv. För att få klarhet i detta har vi genomfört tre gruppintervjuer, där ungdomar i åldern 15-17 år deltog. Vi har i huvudsak använt oss av Yvonne Hirdmans teori om genus och Simone de Beauvoirs tankar om kvinnors underordnade ställning i samhället. Vårt resultat visar att ungdomar inte är så jämställda som de själva anser. Deras svar tyder på att de är polariserade och har tydliga uppfattningar om hur män/kvinnor, killar/tjejer ska bete sig för att bli accepterade av de övriga.

Wavelettransform med Morletwavelets för analys av satellitmätdata

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.
