ABSTRACT Background: Approximately 15 % of all couples in the Western countries experience infertility. Up to half of these cases are thought to solely or partly depend upon the male factor. In most cases male infertility is unexplained. During the last decade there has been a growing focus on sperm DNA damage as a cause of male infertility. Sperm chromatin structure assay (SCSA) is increasingly

När den europeiska konventionen angående skydd för de mänskliga rättig-heterna och grundläggande friheterna (EKMR) inkorporerades genom vanlig lag i svensk rätt, ville lagstiftaren inte att balansen mellan den lagstif-tande och den dömande makten skulle förskjutas. Huvudansvaret för fören-ligheten mellan EKMR och annan intern rätt föll därför på lagstiftaren, vilket manifesterades i grundlagen. KoWhen the European Convention of Human Rights and Fundamental Free-doms (ECHR) was incorporated by law in the Swedish legal system, the intent was to maintain the relation between the legislative power and judici-al power. The legislature is forbidden to legislate in violation of the ECHR. If domestic law is considered to be in conflict with the ECHR, the conflict should, if possible, be solved by

A spectrophotometric assay for plasmin and plasminogen-derived activity in dairy products was optimised and extended to determine plasmin and plasminogen-derived activity in turbid samples of dairy products. The method was validated by assessing reproducibility, repeatability, level of detection and recovery of plasmin activity in different sample matrices. Plasmin activity in raw milk was not aff

In this study, two experiments were conducted to evaluate the impact of substrate concentrations on methane potential and degradation kinetics of substrate. The biochemical methane potential (BMP) tests in Experiment I were performed at a constant inoculum to substrate ratio (ISR), whereas, different ISRs were applied in Experiment II. Results obtained from Experiment I revealed that methane poten

Abstract in UndeterminedThe popularity of the Internet and marketers' increased investments in Internet advertising have raised some questions concerning a marketer's power to influence children and young people's consumption through new media technology. This article, based on a recent explorative study of 15-year-old Swedish teenagers, aims to discuss their exposure-potential, actual, and percei

Den digitala teknikens genomslag har minst sagt haft en stor betydelse för möjligheterna att sprida information, särskilt via globala nätverk som internet. Länken har blivit ett viktigt hjälpmedel för att hitta till och navigera bland på internet tillgängliggjort material. Samtidigt har digitaliseringen medfört att upphovsrättsskyddade objekt nyttjas i en allt större utsträckning och i en gränsöveThe development of the digital technology has had a significant impact on the possibilities to disseminate information, especially through global networks like the Internet. The link has become an important tool to find and navigate among material that has been made available on the Internet. At the same time, digitalisation has lead to an increased use of copyright protected objects, also in a tr

När ett offentligt organ ägnar sig åt offentlig upphandling torde huvudsyftet vara att tillfredsställa ett behov av varor, tjänster eller byggentreprenader. En utgångspunkt för offentlig upphandling är att det är den upphandlande enheten som identifierar sitt behov och således avgör vad som ska upp¬handlas. Utöver syftet att tillfredsställa sitt primära upphandlingsbehov kan en upphandlande enhet When a public body engages in public procurement the main purpose for it to do so is arguably to satisfy a need for goods, services or works. A starting point for public procurement is that it is the procuring entity which identifies its own needs and thus determines what is to be procured. In addition to the purpose of satisfying its primary procurement needs, a contracting entity, however, may h

The participation by Swedish citizens in foreign armed conflicts is a topic that has been receiving an increasing amount of attention not only in the media but also in the political debate. The debate has first and foremost centered around those Swedish citizens travelling to Syria to join various terrorist organisations but the topic extends further, is far more complex and gives rise to a number

Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. Balancing functions that stabilise the grid are referred to as \textit{ancillary services}, which in Sweden include th

Limited information is available on adverse peri-intubation events.Objective To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients.Design, Setting, and Participants The International

The ZZ production cross section in proton-proton collisions at 13 TeV center-of-mass energy is measured using 3.2 fb-1 of data recorded with the ATLAS detector at the Large Hadron Collider. The considered Z boson candidates decay to an electron or muon pair of mass 66-116 GeV. The cross section is measured in a fiducial phase space reflecting the detector acceptance. It is also extrapolated to a t

Theoretical investigations of hyperfine quenching of the two metastable levels 1s(2)2s2p P-3(0) and P-3(2) have been performed along the Be-like isoelectronic sequence for ions between Z=6-22. It is shown that the lifetime of the latter level is sensitive to hyperfine quenching in the beginning of the isoelectronic sequence, but the sensitivity decreases towards the high-Z end. It is also shown th

Popular Abstract in Swedish Ben, brosk och mjukvävnad (utgörs av den tvärstrimmiga muskulaturen, fettväv och fibrös bindväv, men också av det perifera nervsystemet) är vävnader av mesenkymalt eller neuroektodermalt ursprung. De flesta tumörer som uppstår i dessa vävnader är godartade och blir därför ofta inte föremål för behandling, vilket gör det svårt att uppskatta incidensen i befolkningen. EnlBone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoin

Popular Abstract in Swedish Små partiklar i form av vätska eller fast material mellan 0.001 till 100 µm i diameter, kan sväva i luften och kallas då aerosolpartiklar. De påverkar direkt på klimatet genom att reflektera solstrålar ut till rymden. Detta gör att vi får ett kallare klimat. Indirekt kan de påverka klimatet genom att verka som kondensationskärnor vid molnbildning. Med detta påverkar de The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. C, N and O was developed, and methodologies for single-particle analysis

Objective: To investigate the potential of acetic acid supplementation as a means of lowering the glycaemic index (GI) of a bread meal, and to evaluate the possible dose - response effect on postprandial glycaemia, insulinaemia and satiety. Subjects and setting: In all, 12 healthy volunteers participated and the tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden.

Popular Abstract in Swedish Vilka uppfattningar fanns under tidigmodern tid i Sverige om relationen mellan man och kvinna? Ansåg man att kärlek och parternas fria val var viktigt när människor skulle gifta sig? Vad hände då äktenskapen inte fungerade? Förekom skilsmässor? Varför var sexualiteten kontrollerad och hur påverkade det kvinnor och män? Vilken effekt hade förändringar i lagstiftningen i What did people think about the relationship between a man and a woman in Early Modern Sweden? Did they consider love and the parties' free choice to be of any importantance in the making of a marriage? What happened when marriages were falling apart, how common were divorces? I also discuss why sexuality was restricted, and how it affected women and men. What effects did changes in the legislatio

Here we investigated whether microwaves (MWs) of Global System for Mobile Communication (GSM) induce changes in chromatin conformation in human lymphocytes. Effects of MWs were studied at different frequencies in the range of 895-915 MHz in experiments with lymphocytes from seven healthy persons. Exposure was performed in transverse electromagnetic transmission line cell (TEM-cell) using a GSM tes

Allogeneic haematopoietic stem cell transplantation remains the only curative treatment of myelofibrosis with myeloid metaplasia (MMM). Previous reports have indicated significant treatment-related mortality (TRM) for patients transplanted after myeloablative conditioning but superior survival has been reported after reduced-intensity conditioning (RIC). We report the results of a survey of all al
