Kiselalger, vattenlevande, mikroskopiska organismer med kiselskal, används som bioindikatorer för vattenkvalitet eftersom de är artrika och påverkas av sin omgivning. Processen kallas Kiselalgsmetoden och utförs genom en standard, en standard jag valde att analysera. Proven tas från stenar i vattendrag och sedan görs ett preparat som är fixerat på objektglas som kan undersökas i mikroskop genom aDiatoms, water living, microscopic organisms with silicon shells, are used as bioindicators of water quality because they are diverse and influenced by their surroundings. The process is called The Diatom Method and is accomplished through a standard, a standard I have chosen to analyze. The samples are taken from stones in water streams and then a preparation is made to fix the algae on slides t

Under an action research paradigm, this thesis project explores the business potential of an environmental strategy and assesses the formulation of such a strategy implemented by an automotive original equipment manufacturer. Because of the heterogeneous nature of a company’s approach to environmental issues due to inter alia managerial conducts and company culture, this article provides an in-dep

Water is a necessity for human survival, and a lack of sufficient clean water can have severe negative impacts on human health, economic activity, food security and societal relations. Increasing demand on water resources around the globe often leads to conflicts between different water users who compete for available supplies. The Murray Darling Basin (MDB) in Australia is an area that faces many

Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process. When shifting between gears, the speeds of the target gear and the output shaft it is supported by, have to be synch

Significant advancements in audio transport, encoding, and processing power in embedded systems constitute the foundation of today’s speakers. Transitioning the digitalized audio data transmission to Audio over IP (AoIP) has opened the potential to transmit audio with the same network flexibility as other services using packet-based networks, such as voice over IP or video over IP. This thesis pri

Sammanfattning Detta arbete handlar om att kritiskt belysa de aspekter av undervisning som är centrala för mig som pedagog. Som lärare vill jag nå fram till eleven, jag vill att eleven ska ha möjligheten att vara kreativ och att få uppleva det tillstånd som kallas flow. Arbetet har utgått från de upplevelser jag fick av musik när jag var yngre, då tänkte jag inte i termer och begrepp utan upplev

In the early years of EC merger control, the Commission generally concluded that conglomerate mergers would not cause competitive harm. In recent years, however, the Commission has increasingly developed theories of competitive harm which are applicable to mergers which lack appreciable horizontal and vertical effects. The leveraging theory is typically applied in conglomerate mergers, where the m

The Water Framework Directive adopted in December 2000 was to be implemented by the Member States within three years. It requires a holistic approach to be taken towards water resource management and obligates Member States to implement measures that will achieve a general water quality of ''good status'' by 2015. The legal mechanisms required to implement the measures were therefo

The Community relies upon the Member States to execute their obligations. When they fail to do this, there must be a system of enforcement. The topic of this master thesis deals with the main Community enforcement procedure found in Art 226-228 EC, evaluating its state of effectiveness and its development&semic making suggestions of possible improvements. The Treaty of Maastricht introduced an

The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. During activation of such a system, water is assumed to penetrate a significant distance and without interrupti

Abstract Authors: Helena Håkansson & Maria Bergman Title: Spirituality, fellowship and change of way to perceive reality The twelve-step philosophy is regularly occurring both as a common way of treatment and within self-help groups. Alcoholics Anonymous and Narcotics Anonymous as well as several other self-help groups are only a few examples of several organizations who´s foundations are base

Föroreningar på en fastighet berör fastighetsägaren på olika sätt. En direkt effekt av föroreningarna kan vara att fastighetsägarens möjligheter att använda marken begränsas och att värdet på fastigheten påverkas. Det kan också få till följd att fastigheten blir svår att avyttra. Framförallt kan en förorening på fastigheten innebära att fastighetsägaren riskerar miljörättsliga krav på att vidta avPollution of real estate affects the owner in different ways. As a direct effect, the possibilities of using the land may be limited, and the value of the real estate can be influenced. The real estate may also be difficult to sell. Above all, pollution of real estate may involve environmental legal demands on the owner to repair the damage. The main rule of the Swedish environmental code is that

Economic sanctions are defined as the exercise of pressure by one state to bring about a change in political behaviour of another state. Traditional economic sanctions are directed at the entire population of the sanctioned country while targeted sanctions are directed at the State’s government and/or individuals. Iran has become a sanction target first in 1979, which was imposed by United States

BACKGROUND AND AIMS: Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries. Acute mesenteric venous thrombosis is nowadays relatively more often diagnosed with intravenous contrast-enhanced computed tomography in the portal phase than at explorative laparotomy No high-quality comparative studies between anticoagulation alo

Background: Both bullying victimization and perpetration were associated with depression, social phobia, physical and psychological child abuse and Internet addiction in Lebanon. The prevalence of bullying in Lebanon is alarming, with 50% of school-aged children and adolescents reporting being bullied at some point. The high rate of both bullying victimization can be reflective of the inefficacy o

PURPOSE: Radiological assessment of primary brain neoplasms, both high (HGG) and low grade tumors (LGG), based on contrast-enhancement alone can be inaccurate. We evaluated the radiological value of amide proton transfer weighted (APTw) MRI as an imaging complement for pre-surgical radiological diagnosis of brain tumors.METHODS: Twenty-six patients were evaluated prospectively; (22 males, 4 female

Traditionally, automatic control techniques arose due to need for automation in mechanical systems. These techniques rely on robust mathematical modelling of physical systems with the goal to drive their behaviour to desired set-points. Decades of research have successfully automated, optimized, and ensured safety of a wide variety of mechanical systems. Recent advancement in digital technology ha
