Acoustic Focusing in Microdroplets

This thesis examines the possibility to combine droplet generation techniques together with acoustic particle manipulation in microfluidics to achieve focusing of particles inside micro droplets. In the thesis I introduce the reader to the general concepts of microfluidics, droplet dynamics, acoustics and microfabrication which are the basis for my experiments. The practical work focuses on the im

Effects of contaminated irrigation water from the Bahr El-Baqar drain on crops, as determined by experiments with wheat Triticum sp. Port Said, Egypt

Populärvetenskaplig sammanfattning: Effekter av förorenat vatten på grödor Sötvatten är en allt mer begränsad råvara och snabbt växande befolkningar i länder med begränsande vattenresurser är speciella problemområden. Egypten är ett sådant land, vars enda källa till sötvatten är Nilen. Egyptens befolkning var 21 miljoner 1950 och beräknas kunna vara 129 miljoner 2050. Alla dessa människor behöveAbstract The Bahr El-Baqar drain is considered one of the most contaminated waters in Egypt, and along the drain the farmers use its water for irrigation. This study aimed to investigate effects of this irrigation water on crops, with special focus on metal contaminants, using wheat (Triticum sp) as model species. Also, protective effects (against heavy metal poisoning) of adding mycorrhiza form

Genotypic variation in sugar beet (Beta vulgaris L.) affects growth-stimulation induced by Trichoderma harzianum T-22

Popular science summary Growth promoting effects of Trichoderma harzianum on sugar beet Imagine if a plant could be prepared to a pathogen attack before the attack occurs, or if a plant could grow stronger, without an excessive addition of inorganic chemicals.

Vidare undersöktes om det för sambandet mellan ociviliserat beteende och psykisk hälsa spelade roll om utövaren var chef eller kollega. SyfThis master thesis in psychology is part of a research project financed by the Swedish Research Council for Health, Working Life and Welfare (FORTE). The purpose of the present study was to examine the relationship between workplace incivility and mental health.

Runge-Kutta Starters for Multistep Methods to Simulate Systems with Discontinuities

The topic of the thesis is re-initialization of multistep methods for the solution of ordinary differential equations, in which there are frequent discontinuities in first or higher derivatives. There are self-starting algorithms to start or restart a multistep method. It is normally started by first using a one-step method and then increasing the order successively until the working order is reac

Under-utilisation of road freight vehicle capacity: A case for eco-efficiency through collaboration

The road haulage sector experiences a considerable amount of inefficiency, characterised by sub-optimal utilisation of an individual vehicle’s cubic load fill and weight hauling capacity. This study firstly aims to understand why – despite its evident economic and environmental cost – this phenomenon has existed over the years. Next, an overview of initiatives and opportunities for improving freig

Designing Urban Sustainability Regeneration Projects: Case-study: Augustenborg, Malmö

The use of area-based approaches in urban regeneration is widely accepted in the European community. As these projects are based on the context of the focal area, there is no one-size-fits-all solution on how to design and implement those. The Eco-city Augustenborg project is an environmentally-led urban regeneration project initiated in Malmö in 1998. Today, fifteen years after the project was in

Oskyldighetspresumtionen och den talande tystnaden

Principerna om oskyldighetspresumtion och fri bevisprövning existerar med det gemensamma målet att nå så pass materiellt korrekta domar som möjligt. Dessa två rättssäkerhetsprinciper hamnar på ytan i konflikt med varandra när den tilltalade använder sig av sin rätt att tiga för att undvika att belasta sig själv; tystnaden får inte tolkas negativt för den tilltalade, men domstolen är å andra sidan The principles of presumption of innocence and free evaluation of evidence share a common raison d’être in their strife to produce as materially proper judgements as possible. However, these two principles of rule of law seemingly appear to conflict when a suspect exercises his right to remain silent in order to avoid self-incrimination; a suspect’s silence may not be interpreted negatively as evi

Näthat - Vårt nutida ärekränkningsbrott

Ämnet för denna uppsats är näthat vilket kan innebära brott som förolämpning, förtal och ofredande. Men trots att ärekränkningslagstiftningen är vedertagen är den inte helt vattentät. Ärekränkning är ett gammalt hedersbrott som sedan lång tid tillbaka har reglerats i svensk straffrätt. I Sveriges strafflag från 1864 (SL) avsåg förtalsbestämmelsen att värna om den enskildes goda namn och medborgerlThe subject of this essay is net hate, which can implicate felonies such as insult, defamation and harassment.
