Kemisk vittring kallas processen när mineralkorn löses upp och sönderdelas i molekyler eller atomer. Det är en viktig process, bland annat för att den frigör ämnen som skyddar marken från försurning och som fungerar som näringsämnen för växter. För de så kallade baskatjonerna kalium, kalcium, magnesium och natrium är vittringen i marken bland de största källorna. Framför allt de tre förstnämnda baBase cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. One of the largest inputs of base cations to soils is minerals weathering, which makes it an important process. It is, ho

Anaplastic thyroid cancer (ATC) is a rare and highly aggressive thyroid malignancy, usually resistant to conventional therapeutic strategies. The prognosis of ATC is extremely poor with a median survival rate of 6 months. Current treatment therapy includes surgical resection in combination with external radiotherapy and chemotherapy. The underlying mechanisms involved in ATC tumorigenesis is under

Background: Continuously high rates of overdose deaths in Sweden led to the decision by the Skåne County to initiate the first regional take-home naloxone program in Sweden. The project aims to study the effect of overdose prevention education and naloxone distribution on overdose mortality in Skåne County. Secondary outcome measures include non-fatal overdoses and overdose-related harm in the gen

Background: As part of I-O Optimise, a multinational research platform providing real-world insights into the management of lung cancers, the SCAN-LEAF study aims to describe the epidemiology, clinical care and outcomes for pts with NSCLC in Scandinavia. We report initial Tx and OS for pts with NSCLC prior to the availability of immunotherapies in Sweden. Methods: The analysis includes all adult p

Over the last decades, the impact of human activities on the global nitrogen (N) cycle has drastically increased. Consequently, benthic N cycling has mainly been studied in anthropogenically impacted estuaries and coasts, while in oligotrophic systems its understanding is still scarce. Here we report on benthic solute fluxes and on rates of denitrification, anammox, and dissimilatory nitrate reduc

BACKGROUND:The need for instruments that can assist in detecting the prodromal stages of stress-related exhaustion has been acknowledged. The aim of the present study was to evaluate whether the Lund University Checklist for Incipient Exhaustion (LUCIE) could accurately and prospectively detect the onset of incipient exhaustion and to what extent work stressor exposure and private burdens were ass

The method presented in this paper is invented to address the problem of episodic memory in participants with highly restricted verbal abilities, 15-month-olds in this case. Here, we refer to episodic memory defined as a mind/brain system with three main responsibilities: to encode, to store and to recall individual memories. Episodic memory system requires three additional capacities, which make

OBJECTIVE: This study assessed prognostic factors regarding long-term outcome for amputation and death among patients who underwent intra-arterial thrombolysis due to lower limb ischemia. METHODS: Consecutive patients with intra-arterial thrombolysis due to lower limb ischemia treated at the Department of Vascular Diseases, University Hospital of Malmö, between January 1, 2001, and December 31, 20

BACKGROUND: Primary cervical screening with both human papillomavirus (HPV) DNA testing and cytological examination of cervical cells with a Pap test (cytology) has been evaluated in randomized clinical trials. Because the vast majority of women with positive cytology are also HPV DNA positive, screening strategies that use HPV DNA testing as the primary screening test may be more effective. METHO

Air samples were collected on glass fibre filters in 22 animal houses and 3 hay storage barns and examined for the presence of bacterial endotoxin with the Limulus (LAL) test and the gas chromatography - tandem mass spectrometry (GC-MSMS) technique, based on detection of 3-hydroxy fatty acids (3-OH-FAs) as chemical markers of the endotoxin lipopolysaccharide. The median concentrations of airborne

CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc

CONTEXT: Tuberculosis (TB) is an increasing global problem, despite effective drug therapies. Access to TB therapy during conflict situations has not been studied. OBJECTIVE: To determine the effect of irregular TB treatment due to an armed conflict in Guinea-Bissau, West Africa. DESIGN, SETTING, AND PATIENTS: Ongoing retrospective cohort study conducted in the capital city of Bissau among 101 pat

Popular Abstract in Swedish Betændelses reaktionen er kroppens svar på en skade eller en infektion. Betændelses reaktionen gør at immunforsvarets celler kaldes til det skadede område (kan ses som den røde varme hævelse omkring et sår) og at eventuelle sygdomsfremkaldende emner identificeres og bekæmpes. På lidt længere sigt, fjernes ødelagt væv og helingen af såret påbegyndes. Når det skadede områThe pro-inflammatory mediators leukotrienes have shown to be important players in the pathogenesis of diseases like asthma and inflammatory bowel disease (IBD). Patients suffering from IBD have been found to have an increased risk of developing colon cancer. Since leukotrienes have been shown in increased concentrations in stools of IBD patients we hypothesise that LTD4 can play a role in the deve

The present study investigates spatial properties of atrial fibrillation (AF) by analyzing VCG loops synthesized from 12-lead ECGs. During intervals with ventricular activity, the atrial signal is extracted using spatiotemporal QRST cancellation, thus making continuous f-wave analysis possible. Spatial properties are characterized through joint analysis of successive fixed-length signal segments,

Urban Sprawl is one of the challenges to urban development in many nations. Different aspects of the phenomenon have been researched with a view to providing solutions to myriad of ills attributed to it. For any meaningful intervention, however, assessment of development to ascertain sprawl is essential. Despite this, its quantification and monitoring in environment with paucity of data remains a

Background: There are several risk factors for the colonisation, infection and spreading of antibiotic resistant bacteria among elderly residents of nursing homes. An updated estimate of the native prevalence of antimicrobial resistance in uropathogens among Swedish nursing home residents is needed. Methods: Urine specimens were collected for culture and antimicrobial susceptibility testing agains

Summary Title: Taxes and Human Capital as Determinants of Foreign Direct Investment in EU: The role of Most Favoured Nation treatment Author: Andreas Helmersson Supervisors: Cecilé Brokelind and Rikard Larsson Problem discussion and problem Formulation: The recent year’s rapid increase in foreign direct investment (FDI) is a clear indication of increasing globalisation.

The Singhbhum Craton in eastern India is host to at least seven sets of mafic dyke swarms. Four previously dated swarms (studied here) include the NNE-trending Keshargaria (ca. 2.80 Ga) and Ghatgaon (ca. 2.76 - 2.75 Ga) swarms, the ENE-trending Kaptipada swarm (ca. 2.26 Ga), and the ESE-trending Pipilia swarm (ca.1.76 Ga). The dykes range in composition from basalt to andesite and have transitiona
