Most studies done on Drosophila are made in labs and focus on genetics, something which has formed a somewhat one-sided field of studies. To counter this bias, this report was based on fieldwork. From a classical ecological aspect, Drosophila populations in southern Scania were investigated in order to put more clinical Drosophila insights in a proper context. According to previous studies, urban
Genetically modified maize, can it be trusted? In a world with a constantly growing population there is a need to find a way to cultivate enough food for everyone and one of the things that might help with that is genetically modified crops. Genetic modification means that a trait has been given to a plant that it does not normally have. These traits can be resistance to a pest, disease or an her
The Bumbling Bumblebee, they see more than you think! Bumblebees are probably one of the most universally loved insects in the animal kingdom. They don’t irritate you or sting you unlike their relatives, instead they do their own thing while performing their daily tasks of collecting pollen and nectar for the colony. We wanted to learn more about how the bumblebee view the world and how the envir
The Internet, which is the most important component of digitalization, has proved to be a useful, but unfortunately economically difficult channel for the news agency. The rapid shift of digitalization in the 21st century has changed the game plan for traditional fashion journalism. Editors have, through various strategies at the best of their ability, adapted to the new market situation and large
Bird flu: Tracking the virus It is estimated that a whopping 55 million chickens are eaten every day worldwide. They are a main source of proteins in many corners of the world. In developing countries, 20% of all consumption of protein stems from chickens. The industry is dependent on keeping the poultry healthy and safe for consumption. This huge task involves the suppression of natural phenomen
Doftreceptor Or22a och dess betydelse för äggläggning hos bananflugor Vanliga bananflugor har länge använts som testorganismer inom biologisk forskning, så som neurobiologi. Anledningen till detta är att de har ett nervsystem som är lättillgängligt men enklare uppbyggt än däggdjurs (Stocker, 1994,). Luktsinnet hos bananflugor sitter i antennerna och i de maxillära papillerna, som sitter vid flugaThe fruit fly Drosophila melanogaster has a well-studied olfactory system. A crucial part of the olfactory system is the olfactory sensory neurons (OSNs). One type of these OSNs, Ab3a, expresses the Odor receptors (ORs) Or22a and Or22b. Or22a is known to play an important role for behaviors like oviposition, but no strong ligand has been found for Or22b. Recent studies have shown that D. melanogas
Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. Thus, in most cases the information they carry is sensitive, rendering good encryption sch

The main objective of this Master Thesis is to upgrade 16x8 interrupt controller and priority resolver to 128x8 input interrupt lines and adding a debug feature for this customised processo
Wing pigmentation in dragonflies and damselflies (odonates) functions as a secondary sexual trait with a role in courtship and antagonistic male-male interactions. Recently, a thermoregulatory function of wing pigmentation has also been suggested. This study aimed to elucidate how both sexual and natural selection have influenced the evolution and global distribution of wing pigmentation in odonat
Sponges are aquatic filter feeding animals that use internal chambers comprised of choanoflagellate-like cells called choanocytes to pump and filter water. In this study I investigated the behavior of choanocytes in juvenile Amphimedon queenslandica, a coral reef demosponge, when they were fed Photobacterium damselae subsp. damselae compared to when they were maintained in 0.22μm filtered seawater
Diploid potato cultivars that are propagated by True Potato Seeds (TPS) are a new potentially revolutionary way of potato breeding. Conventional breeding is based on highly heterozygous tetraploid potato varieties. Diploid potato breeding by TPS is useful to create inbred lines and from there hybrid offspring. TPS is cheaper, has almost no diseases and is easy to distribute. Diploid potatoes have Are potatoes, grown from seeds, the future? Did you know that you can grow potato plants from seeds? A potato plant has two ways to propagate itself; by the all known potato that we love to eat and by seeds that are grown in tomato-like berries above the ground. These seed producing potato plants that are as well diploid (two copies of every chromosome) instead of conventional tetraploid (4 copie
It was in the early 1980s when Peter Ryan from the University of Cape Town started investigating ecological and conservational factors surrounding the endemic Nesospiza finches in the Tristan da Cunha archipelago, a curious case of resource-driven bird diversification in the Southern Atlantic. Ryan and others suggests for the radiation of Tristan finches to have happened around 400,000 years ago,
In this study, Global Positioning System (GPS)-derived tracking data were used to explore aspects of the breeding season movement ecology of an at-risk seabird, the Caspian Tern, in the Baltic Sea. In particular, the foraging effort, daily activity, and foraging habitat use of the terns were investigated at two breeding colonies. Data were collected during two seasons at the colony on Stenarna isl
SeqCapAnalyst is a pipeline to process .fastq files, producing the standard files as well as statistics useful for singling out good targets for Sequence Capture probes. Rather than speed, it is optimized for flexibility and ease of modification. SeqCapAnalyst is predominantly written in bash, with one module written in Python. The pipeline was tested on sequence capture data which was obtained f
Mikropartiklar är mer än 100 gånger mindre än ett hårstrå. De brukar användas som behållare för läkemedel eller för att markera enskilda molekyler. För dessa ändamål måste ytan på mikropartiklarna modifieras med olika kemiska grupper. Jag har i detta arbete undersökt olika metoder för att binda in protein till mikropartiklar. Som modellsystem valdes mikropartiklar tillverkade av plasten polystyrenMicroparticles of various sizes carrying different surface modifications have numerous technological and biomedical applications, for example to create a larger target for a molecular receptor by binding multiply ligands to the surface of the microparticle. The aim of the present work is to study how to most efficiently couple protein molecules to the surface of such microparticles. In the current
Syftet med den här uppsatsen var att undersöka satsbetoningsmönstret hos exklamativer och vad det gör för den semantiska tolkningen av exklamativen. Detta undersöktes dels genom introspektion, och dels i ett perceptionsexperiment av att-exklamativer. Resultatet av introspektionen visade att att-exklamativers betoning i vissa fall skiljer sig från som- och wh-exklamativers. Detta gäller vid signale
In today's society, much energy is used and all energy use (e.g. heat, electricity) affects the environment. Greenhouse gas emissions from energy affect the climate of the earth and increase the natural greenhouse effect. Environmental impact because of energy use causes both local and global problems. Efficient energy use in buildings is a prerequisite for dealing with climate issues and in t

Kieler Ort, a rather isolated island in the southwest Baltic Sea is representing a unique environment which is protected for its landscape, nature, flora and fauna and serves as a bird sanctuary. Rosa rugosa, as one
Enligt Newsecs rapport från 2016 söker företag idag kontor som har effektiv kontorsyta med stor flexibilitet vad det gäller både area och hyresavtal. Deras analys är att sådana kontor kommer fortsätta att efterfrågas. Vad som menas med flexibla hyresavtal är inget som är självklart i branschen men i detta examensarbete innebär sådana hyresavtal kortare hyrestider och mindre ytor för varje aktör soAccording to Newsec's report from 2016 companies are looking for offices that have efficient office space with great flexibility in terms of both area and lease. Their analysis is that such offices will continue to be demanded. What is meant by flexible real estate leases is nothing that is obvious in the industry but in this paper such leases mean less lease times and less space for each part
The Rural Development Program 2014-2020, is a way of reducing urbanization and creating more equal conditions between urban and rural areas. However, since fiberoptic cables is built on commercial terms, incentives for digging fiber in rural areas are lacking, which means that different types of support are required for construction to be possible. The administrative and financial difficulties req
