Slår bekämpningsmedel ut vilda bin? Vi människor och andra djur är beroende av växter för att kunna leva. Från dem får vi mycket av vår mat och andra produkter som vi behöver i vardagen. De flesta växter är i sin tur beroende av pollinering för att kunna sätta frukt och reproducera sig. Bin är exempel på insekter som är väldigt viktiga pollinatörer. De står för ca 80 procent av all insektspolline

This paper investigates the literature concerning market efficiency and how that compares to behavioral finance. The works of Fama (1970) who laid the ground for the efficient market hypothesis and Jegadeesh & Titman (1993) who laid the ground for momentum strategies are both analyzed and compared against each other. A momentum study on the weekly returns regarding the Swedish stock market (OM

Förändringar av miljöförhållanden i två naturområden i Helsingborg Landskap förändras hela tiden och det sker många stora förändringar genom att vi brukar marken på olika sätt, som till exempel när vi odlar mat. Under det senaste århundradet har det skett många stora förändringar i jordbrukslandskapet, bland annat på grund av att man börjat använda konstgödsel, bekämpningsmedel och har utvecklat Since the 1800’s the agriculture has changed and intensified significantly, going from small scale farming to large homogenous arable landscapes with fewer grazing animals, more fertilizers and pesticides. In Sweden, this pattern of intensification has been very distinct, especially in Scania, which today is dominated by plains. This has left substantial changes in the surrounding ecosystems, affe

The aim of this study is to evaluate the soft tissue response of the pure and Au-embedded PPg-PEG. PP-g-PEG2000, PP-g-PEG4000, Au-PP-g-PEG2000, and AuPP-g-PEG4000 were obtained via chlorination of polypropylene and polyethylene glycol in the presence of a base with a "grafting onto" technique. Solvent cast films of these four copolymers with PP as a control group were embedded into five different

This postgraduate thesis examines various assumption models for energy usage for water heating used in Sweden. The models are compared with the measured energy use in a number of small apartment buildings. Norway and Finland currently use standard models for energy calculations during the production of new buildings but in Sweden the planners are free to select an appropriate model of their choice

Abstract Migration is a widespread phenomenon in nature, observed in many different taxa. Migration is often caused by changes in food availability, physical conditions and predation risks. Moving is energetically costly, and hence migration is likely to be a trade-off between increased survival and an energetic cost for migrating, the cost could take shape in decreased fecundity and lower body c

The Maha Oya (river) originates in the Kandy district of Sri Lanka and travels about 130 km passing four districts to reach the sea at Kochchikade in Sri Lanka. It holds the 3rd largest average annual runoff among the 103 of distinct river basins in Sri Lanka. Its contribution as a fresh water source is of great significance. During year 2004 the river provided five percent of the total production

Att straffa eller att inte straffa unga lagöverträdare och i vilken utsträckning; det är den pågående debatten i Sverige idag. Mer specifikt, huruvida man ska lagföra 18-21 åringar som vuxna snarare än ungdomar. Det torde sig naturligt att individer som anses vara vuxna, lagligen om inte annat, också skall betraktas vuxna nog att kunna stå inför anklagelser i sin fulla omfattning för deras begångnTo punish or not to punish young offenders and to what extent; that is the ongoing debate in Sweden as of today. More specifically, whether or not to prosecute 18-21 year olds as adults rather than youngsters. It would deem natural that individuals considered adults, legally at least, should also be considered adult enough to face charges in its full extent for their committed crimes. However, thi

The demand for high data rates in a wireless communication system has experienced a remarkable growth over the last years. This demand is continually increasing with the growing number of wirelessly connected devices. Thus, there is a continuing hunt for increasing the data transmission rate in wireless communication systems. To increase the data rate, the modern wireless communication system cann

Otaliga mängder kritisk information om vår hälsa spolas ner varje dag. En toalettsits med osynligt inbyggd radar kan ta tillvara på denna information. Alla besöker toaletten varje dag, därav är den fylld av kliniskt relevant information, som hittills sällan använts för att övervaka hälsan. Förändringar i urin- och avföringsmängd, samt avföringens konsistens kan vara tidiga tecken på sjukdom, men rConstipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a

The purpose of this study was to investigate the early alterations of retinal function, assessed with electrophysiology, in newly onset type 2 diabetes patients without vascular retinopathy. Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG

Popular Abstract in English Vernacular (local) architecture is in danger and about to disappear in several parts of the world. What we call native, traditional and handmade will disappear gradually and then the true meaning of vernacular vanishes. The present thesis shows that the disappearance of vernacular traditional skills creates an increasing threat to the existence of desert vernacular archDesert vernacular architecture has always been the product of a sustainable building cycle. People inherited the traditional way of building from their ancestors and the knowledge was transferred and developed from one generation to another. Inhabitants responded to their environment and climate through trial and error in a way that satisfied their needs and aspirations to create a developing buil

This dissertation examines the effects of the three major lexical form-classes in English (nouns, lexical verbs, and adjectives) on lexical infelicity in the English of adult advanced Swedish learners. By lexical infelicity is meant deviations from the native English norm in meaning only. Morphological form is not taken into account. It has previously been established that there are some clear, di

This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. When the error score for the first test opportunity is compared with th

Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated
