This work evaluates the efficiency and quality of drug substance and product automated sample preparation for liquid chromatography analysis in comparison to the manual preparation technique. Despite the potential advantages of process automation in improving efficiency, accuracy, and precision while reducing time and resources, sample preparation in the early phases of drug development in the ph
Intensive agricultural practices can dramatically change the landscape, thereby increasing the concentrations and rates at which nutrients are delivered to aquatic ecosystems. In the United States, concerns about accelerating rates of lake eutrophication related to increases in nutrient loading require a method of quantifying ecological changes that have occurred since European settlement. Because
During the latest years there has been a strategic decisive change when it comes to how the larger producers regard and treat their subcontractors. This is partly due to the increasing globalization and the fact that the economy is becoming more and more knowledge and networks based. The subcontractors are facing higher demands from the producers to deliver system solutions with more complex compo
"Diffusion magnetic resonance imaging (MRI) is today a well-established method in clinics around the world. For example it is a leading method or diagnosing ischaemic stroke at an early stage. Trough research it is a continuously growing field applicable to many different tasks. Alternatively, the diffusion MRI can be used for morphologic studies by the use of q-space analysis. q-space imag
Summary: The Kiruna ore is situated in northernmost Sweden, and it is one of the largest iron ore deposits that is known in the whole world. Small amounts of cobalt occur in the ore. This paper is devoted to the study of the distribution of cobalt in the Kiruna ore. Results from studies under the polarizing microscope in both transmitted and reflected light in addition to chemical wholerock analys
This Master thesis was carried out in cooperation with BAE Systems Hägglunds in Örnsköldsvik and its purpose is to improve the efficiency of the hydraulic system for the cooling fan drive in the track driven military vehicle BvS10. The efficiency of the pump and motors are summarized using data from the subcontractors and the efficiency of the pipe line system is derived using Bernoulli's for
Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. Among those, the digital pre-distortion tends to be the m
Förslaget om att införa anonyma vittnen i Sverige har fått större medialt utrymme på senaste tiden. En anledning är den grova gängkriminaliteten, och utsattheten hos vittnen, som av många antas vara ett resultat av den. Några debattörer uppger eller antyder att de tidigare motsatt sig tanken om anonyma vittnen men att den nya situationen med gängkriminaliteten har ändrat deras uppfattning. UppsaThe idea of a system which would allow anonymous witnesses in Sweden has received increasing media attention recently. One of the reasons is the serious gang criminality, and the threat to witnesses, which by many is assumed to be a result of that. Some of the debaters state or imply that they previously were opposed to the idea of anonymous witnesses but that the new situation with the gang crimi
Climate hazards are increasing globally both in their intensity and frequency, requiring more integrated approaches that also strengthen national leadership over disaster management. Mobilizing resources ex-ante has been demonstrated as an effective way of reducing the impacts of hazards on livelihoods and protecting development gains, while social protection (SP) has also been demonstrating capac
This essay contains an analysis of the International Court of Justice's advisory opinion on the Israeli Wall and a comparison between this judgement and others from the Court regarding the right to self-defence. Moreover, State practice and doctrine on the subject will be evaluated. The wall, or the 'security fence', built by Israel on Occupied Palestinian Territory, has become the wor
Cosmetic innovations are about finding high performing creative solutions that deliver into the consumer trends. The consumer trend within the cosmetic industry is currently driving a growing demand for more clean, natural skin care products with sustainable credentials. Enhanced delivery to and interaction with the skin can be achieved through knowledge-based design and characterization of delive
Thesis purpose: The purpose of this study is to understand what impact social media influencers have on consumers' online behaviour. We further aim to understand the interrelationship between social media influencers and online impulse buying behaviour. Methodology: This study has utilised a qualitative methodology based on a social constructionist philosophical position. The study has adopte
Background: Preterm birth is the primary cause of the neonatal mortality and morbidity. There will be no preterm birth without a cervical softening. Nitric oxide ( NO) is shown to be a mediator of term cervical ripening. The aim of this study was to investigate mRNA expression of the three isomers of NO synthases ( NOS) and to identify them by immunohistochemistry in the human cervix at preterm bi

A study of heavy metals in surface and groundwater was conducted in Poopó and Antequera River basins in Bolivia. Problems with high levels of heavy metals in waters on the Bolivian high plateau have been known for many years and are to a great extent the cause of the mining industry in the region. In this study, ten sampling sites of surface waters and twelve observation wells monitoring the groun
During the last decade, upconverting nanoparticles (UCNPs) doped with rare-earth (RE) ions have been extensively studied in the field of biophotonics. Due to their unique properties of anti- Stokes shifted luminescence and with excitation and emission wavelengths optimal for biomedical imaging, they have become an interesting class of fluorescent contrast agents. An issue with downconverting fluor
The Atankwidi River Basin is situated in the Upper East Region of Ghana. The Basin has an area of around 275 km2. The semiarid climate in which the Atankwidi is situated is characterized by one rainy season spanning from April to September and one dry season spanning from September to April. All of the year’s precipitation falls during the rainy season – roughly 1000mm – with a peak downfall in Au
