Sealings are an important part in the industrial robot. One important property of the seal is to keep all particles and fluids from the outside, away from the important components inside the robot. Another important property is to keep the oil and grease inside the robot, and prevent leakage. The seal also prevent leakage inside the industrial robot and reduces the risks of sensitive components to
I en tid präglad av globalisering, teknisk innovation och individualism har kampen om talangfulla medarbetare vuxit fram. Arbetsgivarens behov av att framstå och uppfattas som attraktiv har kommit att bli betydande, speciellt i relation till Generation Y som olikt tidigare generationer byter arbetsgivare flera gånger under sin yrkeskarriär. En generationskohort, så som Generation Y, består av indiIn an era characterized by globalization, technological innovation and individualism the battle for top talent has emerged. Employers’ need to be seen and perceived as attractive have become significant, especially in relation to Generation Y that unlike previous generations change employer several times during their professional careers. A generational cohort, as Generation Y, consists of individ
When referring to the same event, people can have different assumptions. What is interesting to see is why these assumptions are different, why do people have different stories? Some of the reasons could be different levels of expectation, different communication channels or even different cultural backgrounds. We have analysed all these by having a case study within a company that has recently go
In this paper, we carried out a systematic literature review to document the emerging scientific knowledge about COVID-19 impact on livestock systems and food security in developing countries to identify gaps and possible avenues for future research undertakings. Specifically, we systematically reviewed 68 peer-reviewed articles extracted based on rigorous selection criteria fromScopus, PubMed and
Introduction: Grey pea is a largely overlooked legume in the Nordic countries, and its potential uses in various food products remain unexplored. It is a nutrient-rich crop with low environmental impact, making it an attractive option for sustainable and nutritious plant-based alternatives. Objectives: To investigate the impact of dehulling, germination, and fermentation on the bioactive (pol
The elemental composition of the St. Louis aerosol has been investigated at rooftop sites in south and central locations in the city as part of the August, 1973 field season of the Regional Air Pollution Study of the U.S. Environmental Protection Agency. Sampling by 5-stage cascade impactor with backup filter permits analysis by proton-induced x-ray emission (PIXE) of size fractions of aerodynamic
Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. The purpose of this work was to study the degradation of organic matter at WWTPs within two areas in particular; 1) d
The way in which the cortical cytoskeleton associates to the plasma membrane (PM) must be elucidated to understand the structural dynamics of many processes in the plant cell. In the present study, isolated cauliflower (Brassica oleracea L.) PM vesicles were used to characterize membrane/cytoskeleton interactions. Both actin and tubulin were shown to copurify with PM vesicles and this copurificati
Abstract in UndeterminedThe objective of the report is to analyse simulation results coming from the use of a policy evaluation method that encompasses a wider set of determinants for technology choice. To that end, we use the EEB_Sweden model v1.0. Still in an early stage of development, the model offers an opportunity to capture or integrate critical modelling aspects that justify our research p
The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely
The fundamental question posed in this study is how to approach the construction sector in order to cover its wide scope of activities, its great variety of actors and the external influences on it from the market and institutional environment. Construction includes such diverse economic activities as new production and as repair/maintenance, itinerant production and stationary manufacture, the pr
Popular Abstract in Swedish Avhandlingen består av fyra kapitel som behandlar olika aspekter av internationell handel och dess effekter på konkurrens och produktivitet. Särskilt behandlas effekterna av EU:s expansion och fördjupade integration. Första kapitlet använder den så kallade gravitationsmodellen för att analysera hur integrationsprocessen av de Central- och Östeuropeiska länderna i EU haThis thesis consists of four papers on trade, competition and productivity with particular emphasis on the effects of various aspects of the deepening and widening of the European Union. The first paper Trade Creation, Diversion and Displacement of the EU Enlargement Process provides an assessment of the effects of the EU enlargement process on trade. A new method of estimating the gravity model
The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. These systems are realized by computationally complex algorithms, r
The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. At low concentrations of denaturant the transition state occurs early in the folding reaction, whereas at high denaturant concentration it moves close to the nati
Analysis methods are currently being miniaturized in order to save time and money while achieving higher sensitivities. The ultimate goal is to create a lab-on-a-chip where all analysis steps and instruments can be automated and integrated into a single chip. In order to perform cellassays and microparticle based bioassays on chip, methods to manipulate particles and cells in microsystems are desi
This thesis is comprised of five papers that are all related to the subject of financial time series. We study statistical aspects of conditional heteroskedastic models commonly used in modelling financial volatility. Paper I discusses the performance of commonly known information criteria in the presence of various GARCH processes. The investigation has been performed using Monte Carlo simulatio
The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang
