We present a theoretical study of the absorption of light in periodic arrays of InP nanowires. The absorption in the array depends strongly on the diameter and the length of the nanowires, as well as the period of the array. Nanowires of a length of just 2 Am are able, after an appropriate choice for the other parameters, to absorb more than 90% of the incident energy of TE and TM polarized light,
Sweden is renowned for its centralized wage bargaining system, which has been studied for decades from the point of view of inflation, wage differentials and unemployment. A coordinated system in place since 1997 has been compared to the centralized system of the postwar era, while other scholars have pointed to differences in how the institutions work in practice. This paper studies media coverag
Lipase-catalyzed alcoholysis of triolein dissolved in ethanol or isopropanol for the formation of ethyl and isopropyl esters was investigated. Of 16 lipases screened, Amano lipase from P. fluorescens was selected for investigation of the effects of basic reaction conditions on alcoholysis yields. Ethanolysis yields were only slightly affected by water additions to immobilized lipase preparations.
While current instruments of EU economic policy coordination helped stave off a full- scale depression, the post-2007 global financial and economic crisis has revealed a number of weaknesses in the Stability and Growth Pact, the EU framework for fiscal surveillance and fiscal policy coordination. This paper provides a diagnosis of how the SGP faired ahead and during the present crisis and offers a
In vitro studies of titanium and TiO2 as well as other metals were carried out to investigate the role of these metals in the inflammatory response through the Fenton reaction. The TiOOH matrix formed traps the superoxide radical, so that no or very small amounts of free hydroxyl radicals are produced. Ellipsometry and spin trapping with spectrophotometry and electron spin resonance (ESR) were use
The main goal of prostate cancer tissue biomarkers is to improve diagnostic and prognostic accuracy. A particularly important question is whether the cancer needs immediate treatment or if treatment can be deferred. It is highly unlikely that a single biomarker that provides comprehensive prognostic information about a newly diagnosed prostate cancer will be forthcoming. Despite extensive research
The focus of this project has been to find a method on how to do production improvements systematically in the case of manufacturing by means of metal cutting operations. Typically every company determines their cutting data with the help of previous experiences as well as recommendations made by the tool manufacturers. These chosen cutting data may be the optimal settings for the specific operati
It is well known that one of the major limitations to achieve good performance in mechanical systems is the presence of friction, which is a nonlinear phenomenon difficult to model. In a recent paper Canudas and co-workers proposed to represent it with a nonlinear dynamical model. The friction compensation problem with this model is stymied by the fact that the parameters are uncertain and some of
We present the DEAL language for heap assertions that are efficiently evaluated during garbage collection time. DEAL is a rich, declarative, logic-based language whose programs are guaranteed to be executable with good whole-heap locality, i.e., within a single traversal over every live object on the heap and a finite neighborhood around each object. As a result, evaluating DEAL programs incurs ne
In high energy pp scattering the inclusive cross section for minijet production is very large. Unitarity then implies a high probability for multiple interactions, and a large diffractive cross section. As the proton has a substructure in terms of parton cascades, the diffraction is not only elastic, but has a large component of diffractive excitation. The cascades can fill the whole rapidity ran
A very simple and extremely computationally efficient algorithm for blind separation of two speech sources from two mixtures is presented in this paper. The algorithm exploits the approximate W-disjoint orthogonality of speech signals and assumes specific sensors (microphones) setting that allows the sources to possess a feature we call cross high-low diversity. Two sources are said to be cross hi
The scale and legal implementation make the Swedish deinstitutionalization process for people with intellectual disability (ID) a particular experience. The aim of this study was therefore to explore this experience by analysing the political problematization/s of institutional residence that were made in connection with the political decision to start the deinstitutionalization process. Utilizing
In an industrial plant availability is an important factor since increased availability often gives an increase of final production which in many cases means an increased profit for the company. It has been shown that good strategies for buffer management could increase the availability of an entire plant which motivates further research in this area. To be able to compute the optimal solution to
A frequently asked question is if owning real estate is a good asset to diversify one's portfolio from the stock market. A common perception is that it favors the portfolio since the two assets are segmentated. Earlier studies came to the conclusion that there is a weak or even negative correlation which is often considered as the basis for this argument. The question is if the stock market an
Abstract Globalisation has lead to changes on many levels of our society; -industrial, technological, and corporate to name a few. This is an ongoing process which affects the society we live in today. The process is affecting the working-conditions for everyone through the changes of the relations on the working market. The unions have enjoyed a very special role in Sweden for a long time, but t
The purpose of this essay was to examine what social functions the local pub provides to its regular frequenters, as well as the significance of the pub in the regulars? life. Essential questions were: For what purpose do the regular frequenters visit the pub? What are the routines of the pub visit? Can regular frequenters be viewed as a homogenous group, and if so, what are the prevailing norms i
The aim of this university paper was to understand how eight former clients at Staple reformatory had experienced their stay there. The clients at Staple are young people between 13-20 years old, both boys and girls. The basic questions were: What picture do the clients have of the treatment they received? What has been, from their perspective, the most important during their stay? Do the client
The Human Rights-Based Approach is an approach on development programming designed by the UN. It brings together all human rights principles recognized in our modern history eventuating in a normative framework. This framework is huge, containing complex concepts that each can be read in multiple ways. The result from this is a mess – talking a lot without saying much. Somewhere among all the fanc
