The standard model (SM) of particle physics is spectacularly successful, yet the measured value of the muon anomalous magnetic moment (g - 2)mu deviates from SM calculations by 3.6 sigma. Several theoretical models attribute this to the existence of a "dark photon," an additional U(1) gauge boson, which is weakly coupled to ordinary photons. The PHENIX experiment at the Relativistic Heavy Ion Coll
To identify weather controls of beech diameter growth and masting in southern Sweden, we analyze records of monthly weather, regional masting record, and tree-ring chronologies from five beech-dominated stands. The results indicate a strong weather control of temporal pattern of masting events in southern Sweden over the second half of the 20th century. Negative summer temperature anomaly 2 years
G.fast is a new standard from the International Telecommunication Union, which targets 1 Gb/s over short copper loops using frequencies up to 212 MHz. This new technology requires accurate parametric cable models for simulation, design, and performance evaluation tests. Some existing copper cable models were designed for the very high speed digital subscriber line spectra, i.e., frequencies up to
This study investigated the effect of glow discharge treatment of titania surfaces on plasma protein adsorption, by means of ellipsometry and mechanically assisted SDS elution. The adsorption and film elution of three plasma proteins, viz. human serum albumin (HSA), human immunoglobulin G (IgG) and laminin-1, as well as competitive adsorption from a mixture of the three proteins, showed that the a
Corporate cash holdings have an important role in the financial management of corporations. Firms hold cash for various reasons, Keynes (1936) states the reasons to be of transaction, precautionary and speculative nature, respectively, and firms’ cash policies differ both on an industry and firm level. Previous empirical studies mainly deal with the determinants and behavior of corporate cash hold
Remittances are getting wider attention in recent years because of the enormous increase in amounts. Remittances have already outshined the inflow of FDI, official development assistance, and portfolio flows for many developing countries. However there is no clear-cut understanding of its macro level importance to economic growth which arises because of shortage of study in the area. This study tr
Tanzania is today one of the greatest aid recipients in the world, but still - after over 45 years of huge amounts of aid - one of the poorest and least developed countries. How can that be? Civil society is said to benefit the democratization process, but has not succeed in Tanzania. Has the extensive aid had any impact? Our purpose is to investigate this set of problems. We are using theories c
Our purpose has been to review and analyse the representation of rape, as well as discussions concerning rehabilitation, present in texts targeted at professionals and/or female victims of rape. We wish to investigate whether female victims of rape themselves are given the opportunity of individual positioning with regard to the crimes they have been exposed to. We consider it to be of relevance t
This bachelor thesis focuses on the ethics concerning the possession of nuclear weapons seen from a deontological and utilitarian perspective. I have also considered the aspects of International law, the Just-war Theory, and Michael Walzer's Legalist Paradigm. The research question that guides my essay is: Is it possible to ethically justify a country's possession of nuclear arms, which re
The proliferation of renewable energy resources is imposing demands on electric distribution infrastructure that traditional low-frequency transformers are not equipped to fulfill. Conventional transformers operate with high energy efficiency but offer zero active controllability with no inherent power quality management and support for hybrid power flows. The solid state transformer (SST), a powe
BACKGROUND: Non-operative treatment for acute appendicitis (AA) in children has gained acceptance as an alternative to surgery in selected cases. Accurate preoperative differentiation between perforated and non-perforated AA is increasingly important, as the former requires emergency surgery while the latter may be managed conservatively. Previous research has suggested that low plasma sodium conc
Popular summary: Air quality data mart built in this study consists of historical air pollutant data for cities across Ontario. This data is available at the Ontario ministry of environment website from 2000-2007 for most of the cities. There is missing data for some of the cities and some pollutants as well. It is because the monitoring of those specific pollutants did not commence in or before 2
In both Swedish political discourse and in Swedish media the phenomenon known as begging is a topical issue. The purpose behind this study was to examine the attitudes and notions toward the phenomenon of begging among social workers within the voluntary and public sector, and also their position on responsibility in relation to this reality. The empirical base of the study was formed by semi-stru
When a video sequence is recorded in low-light conditions, the image often become noisy. Standard methods for noise reduction have difficulties with motion. But the interesting parts in a video is often the ones that are moving, for instance a burglar captured in a surveillance video. One approach for denoising video sequences is to use temporal filtering controlled by optical flow, which describ
The aim of this study was to examine the effects of the liberalization wave which is sweeping across America in recent times, and how it influence our way of thinking and working with marijuana in Skåne, Sweden. To understand how it’s affecting us my study are based on interviewing social workers and other professionals working with marijuana and other narcotic related problems. My interviews were
Melanin is a group of pigments present in almost all kingdoms of life. It has many interesting properties such as high fossilizing potential and the ability to chelate metals. The binding of metal ions is believed to have two major functions within biological systems: metal reservoir and metal scavenger. However, eumelanin’s chemical structure is still unknown and there is a knowledge gap regardin
In the near future, our species, and many others, face an upcoming shock in the global climate; one that could result in the potential extinction of more than just the human race. In order to combat this issue, the field of sustainability emerged throughout different sectors of society. One of the places that this topic has blossomed is within academia, and there are few things more important than
Since the end of the 20th century, society has gradually moved towards an information society where the use of the internet and the management of information has grown to become more important. While discussing digitization in the construction industry, BIM is oftentimes mentioned. Simply put, BIM is a 3d-model comprised of unique objects containing different types of information.
