Liquefaction of coagulated human semen was inhibited by o-phenanthroline; subsequent addition of Zn2+ reversed this inhibition, but not if the coagulum was repeatedly washed before Zn2+ was added. No liquefaction of the coagulum occurred when Fe2 was added (in a 1:3 molar ratio to o-phenanthroline), and the gel repeatedly washed. This o-phenanthroline-depleted coagulum was liquefied by resuspended

Phenol is a commonly used preservative in pharmaceutical protein solutions. It is compatible with most proteins but can cause aggregation and denaturation at higher concentrations or in more sensitive proteins. By titrating phenol in 12 different protein solutions with PS80 (Lysozyme, β -lactoglobulin, SOBI Lipase, GA-Z, Palifermin and Trastuzumab, all with and without NaCl) the phenol concentrati

I vårt samhälle används idag tekniker för att kunna göra flera vardagliga funktioner. Det finns dock risker med detta då det kan ge tillgång till mycket känslig information. ID-kapning är en risk som innebär att din identitet används av obehöriga på ett olagligt sätt och detta kan ske via social engineering attacker. Syftet med arbetet är att undersöka svenska internetanvändarna medvetenhet till I

The purpose of this thesis is to examine how the exposure of the coastal population of Kalimantan, Indonesia changed as a result of coastal mangrove loss and population growth. The change of exposure has therefore been calculated through the loss of mangrove biomass, through deforestation and degradation, over time, as well the increase in population living within 10km2 of disturbed mangroves. TheMangrove ecosystems have the potential to provide a host of ecosystem services to the communities surrounding them. Dense, healthy, networks of mangroves are able to provide a buffer to coastlines against the increasingly frequent and intense storms, expected under the influence of climate change. Additionally, healthy, mangrove ecosystem provide coastal communities with other benefits such as mor

I den här rapporten designas två möbelserier innehållande fåtölj, soffa och soffbord i varje samt väggmoduler som kan byggas samman. Dessa möbelserier samt väggmoduler skall tillverkas genom additiv tillverkning, även kallad 3Dutskrivning. Möblerna görs i termoplaster för att materialet skall enkelt kunna återanvändas till att skriva ut nya möbler i ny eller samma design då användaren vill byta ut

Neighborhood attachment is an important and influential concept in environmental psychology. Yet, there is a lack of quantitative research that allows predictions to be made. Additionally, whereas neighborhood attachment is influenced by various variables, most studies only have assessed a few predictors. A quantitative study with cross-sectional design was conducted in order to create a comprehen

Bakgrund: Fysisk aktivitet i klassrummet har visat sig ge ökat fokus och förbättrar skolresultat bland elever. Att ägna en kort stund av lektionstiden åt fysisk aktivitet minskar också stillasittandet och dess negativa effekter, där så lite som två minuter är tillräckligt. Syfte: Syftet med denna studie var att kartlägga integreringen av fysisk aktivitet under lektionstid för att minska stillasitt

Objectives: To understand the comparability of serum prostate-specific antigen (PSA) determinations across assays and storage time. Methods: Serum PSA levels were determined for men aged 40 to 79 years from the clinical subset of the Olmsted County Study of Urinary Symptoms and Health Status Among Men on fresh samples and after a median of 32 months on banked samples, frozen at -70 °C. Baseline se

Local tumor-associated immune cells hold prognostic and predictive value in various forms of malignancy. The role of systemic, circulating leukocytes is, however, not well-characterized. In this prospective and explorative study, we aim to delineate the clinical relevance of a broad panel of circulating immune cells in 32 patients with newly diagnosed metastatic breast cancer (MBC) before the star

PurposeArterial stiffness is independently associated with orthostatic hypotension in older individuals. The relationship between orthostatic blood pressure adaptation and aortic stiffness has not been thoroughly examined in a younger population. We investigated the relationship between orthostatic blood pressure adaptations, central aortic hemodynamics, and aortic stiffness in a cohort of predomi

Background. Prostate specific antigen (PSA) is a zymogen of a 33‐kilodalton (kD) serine proteinase with extensive similarity to glandular kallikreins. The mechanism responsible for converting the zymogen into active proteinase has not been defined, but active PSA may be irreversibly inactivated in vitro by two of the major proteinase inhibitors in blood: alpha1‐antichymotrypsin and alpha2‐macroglo

Serum γ-glutamyltransferase (EC 2.3.2.2) showed microheterogeneity on electrofocusing, owing to variations in sialic acid content. We investigated the isoform patterns of papain-treated serum samples on agarose gels containing nonionic detergent and ampholytes in the low pH range. Serum from cases of cholestasis show seven bands with γ-glutamyltransferase activity. These same bands were also found

Decarbonizing society will require a shift toward renewable electricity production. However, the temporal configuration of renewables requires that demand adapt accordingly. Introducing intermittent electricity production will thus require end users to be more flexible in their use of electricity. Flexibility capital has been promoted as a concept for analyzing material preconditions in order to u

The transformation of the energy systems will call for new turbomachinery designs for harvesting low-grade heat. The word “low-grade” has many definitions and ranges from levels where steam is the preferred selection to very low grades where specially adopted ORC technology is used. In this work, turbomachinery for cascading the steam cycle with a very low-temperature ORC technology is studied. Th

Background: Recent findings have shown that imaging voluntarily activated motor units (MUs) by decomposing ultrasound-based displacement images provides estimates of unfused tetanic signals evoked by spinal motoneurons’ neural discharges (spikes). Two methods have been suggested to estimate its spike trains: band-pass filter (BPM) and Haar wavelet transform (HWM). However, the methods’ optimal par

Opportunities and barriers for occupational engagement among residents in supported housing. Background: Research shows that people with psychiatric disabilities view supported housing (SH) as a possibility for social contact, but also as entailing a risk of deprived self-determination. There is, however, little research on the target group’s engagement in everyday occupations. Aim: To explore SH

Det här studien betraktar gudstjänsten i en Pingstförsamling med hjälp av Randall Collins teori om interaktionsritualer. Deltagande observationer tillsammans med en kompletterande intervju, samt spontana samtal i samband med observationstillfällena, utgör det material som ligger till grund för analysen. Syftet med studien är att undersöka vad som händer i människor när de firar gudstjänst tillsamm

Migration is a globally studied social issue, that can cause changes in the demographic composition of the population and the structure of society. Azerbaijan has been experiencing different waves of migration in the country since gaining its independence. One of the largest waves is the emigration from rural to urban areas. Although there are studies focusing on why people leave the villages, th
