In order to produce drinking water, coagulants - such as aluminium salts - are widely used for precipitation and separation of impurities from raw water. The residual from the process is sludge, which presents a disposal problem. The REAL process is a method for recycling the aluminium from the sludge. In a first step, the aluminium hydroxide is dissolved in sulphuric acid. In a second step, an ul
This statement examines the relation of the resting ECG to its technology. Its purpose is to foster understanding of how the modern ECG is derived and displayed and to establish standards that will improve the accuracy and usefulness of the ECG in practice. Derivation of representative waveforms and measurements based on global intervals are described. Special emphasis is placed on digital signal
An increasing incidence of testicular cancer has been reported from several western countries during the last decades. According to current hypothesis testicular cancer is initiated during the foetal period and exposure to endocrine disruptors such as some persistent organic pollutants has been of concern. We have previously reported the results for concentrations of polychlorinated biphenyls (PCB
The purpose of this Phase II study was to evaluate if alum-formulated human recombinant GAD65 is safe and does not compromise beta cell function. The study was conducted as a randomized, double blind, placebo-controlled, dose-escalation clinical trial in a total of 47 Latent Autoimmune Diabetes in Adults (LADA) patients who received either placebo or 4, 20, 100, or 500 μg Diamyd subcutaneously at
This review of the educational tools developed to promote peace in Uganda sought to answer two primary questions through qualitative elite interviews and secondary research: is the Government of Uganda (GoU) actively trying to promote peace by promoting education? and what are the tools being used? A lens made of peace education theory was employed to assess those questions while the relationship
Parallel kinematik machines are nowadays an important branch of investigation in the robotics field. Its design allows for high speeds, accelerations and tool forces as well as makes them ideals for faster cycle times and high repeatability works. TAU is a parallel kinematic machine from ABB Company with three degrees of freedom. Therefore, it can be positioned anywhere of the workspace but not or
Formula Student is an international inter-universities competition about designing and building a single-seater racing car. One of the most important parts in a car is the suspension system, from the tires to the shock absorbers. This Master Thesis’ report goes through all these parts, looking to theory, different design options, the constraints (rules, economical, packaging, etc) and the final de
The Republic of Moldova is celebrating 20 years of independence and is still almost completely dependent on energy imports from the Russian federation. Renewable energy is in its infancy despite a climate that is well suited for solar and wind energy with 2,300 sunshine hours per year and measured wind speeds up to 8.5 m/s. Moldova has a history of wine production and wide spread usage of more tha
This thesis investigates the driving forces behind the debt level in the Swedish counties, the possibility that the metropolitan areas are different from the rest of the country and presents a short discussion about possible policy actions to address this matter. The results show that housing price and supply, wealth, income and average age have a significant impact on the debt level where a diffe
A new optical interferometer for delay stabilization in attosecond pump/probe experiments is constructed, featuring a custom-made hole-drilled recombination mirror and using a co-propagating HeNe laser for the interference. The interferometer is shown to generate an interference pattern of high enough contrast for delay stabilization. The stability of the measured delay is tested with the interfer
This study focuses on the part of the policy process called implementation. Theorists like Lipsky (1980) and Rice (2012) assign the street-level bureaucrats a major role in this process. The street-level bureaucrats of object in this study are personnel on group homes for unaccompanied minors. Since the children do not have anyone else to look after them, it is the welfare states responsibility to
After the economic recession suffered during the eighties decade, the population under poverty conditions has increased dramatically. With the purpose of amend the situation; President Carlos Salinas has established the biggest anti-poverty program in Mexican history, the Programa Nacional de Solidaridad (PRONASOL). The following three administrations continued the implementation of these policies
Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. I denna uppsats utforskas möjligheten att applicera metoden med digitalkameror på ett nyligen kalhugget område för aAbstract The use of inexpensive digital cameras in phenological research has been acclaimed since results in previous research have shown that they are reliable and precise in measuring greenness of vegetation. The work of this thesis aims to broaden the applicability by studying how well the method performs when measuring the regrowth of a clear-cut area. This is needed to complement existing res
The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main
