Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

BACKGROUND: This prospective study compares results of infrainguinal revascularisation with autologous vein in diabetic and non-diabetic populations.PATIENTS AND METHODS: 101 patients (diabetics (A) n = 50 and non-diabetics (B) n = 51) were operated upon with an in situ saphenous vein bypass to the popliteal artery below knee or to crural arteries, due to critical ischemia. Data on operative detai

Background and aims The pathogenesis of abdominal aortic aneurysm (AAA) shares several common pathways with atherosclerosis. Prospective clinical plasma biomarker studies in AAA have been hampered by the need for very large cohorts and long follow-up time. Methods We analyzed a prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer st

Tracking activities have lately been very popular in smartphones, which requires that the devices are able to classify activities correctly. Since this type of devices has limitations in both power consumption and computational performance, it is important to keep these factors to a minimum. Therefore, the low cost of the accelerometer sensor is a good platform to build a classification on. Althou

The use of computer models in research and development is a powerful tool to make the engineering process more effective. By providing accurate simulations, the need for working prototypes and extensive testing is reduced. This Master’s Thesis investigates the Gambro WRO 300 H reverse osmosis water purification system with the aim of creating a working and easily adaptable computer model of the ma

Under det senaste seklet har det svenska samhället utvecklats från att ha varit ett industrisamhälle till att bli ett kunskapssamhälle. Denna utveckling har inneburit att s.k. kunskapsföretag har kommit att få en alltmer central roll i samhället. Kunskapsföretag kännetecknas av att de främst bedriver kunskapsproduktion och inte materiell produktion. Det är de anställdas kunskap som utgör kunskapsfDuring the last century, the Swedish society has developed from being an industrial towards becoming a knowledge-based society. As a consequence, so-called knowledge management-companies have come to occupy a central role in society. Knowledge management-companies ́ primary production is knowledge and not matter. Since the employees possess the knowledge, they are the most valuable resources of th

The aim of this study was to explore the way out of homelessness for women with children and a history of substance abuse. The study population were women who had personal experience of being homeless, a substance abuser and a mother, but had left the homelessness and substance abuse behind. Four semi-structured interviews were conducted with four different women, and the empirical material was th

Du vaknar på morgonen kollar på din mobiltelefon om det hänt något nytt och spännande, tar datorn med dig till jobbet eller plugget och efter en lång dag sätter du dig i soffan och slår på Tvn. Alla dessa prylar har en central roll i vår vardag och är baserade på en gemensam nämnare som möjliggjort detta– transistorn. I din mobiltelefon finns det ungefär 200 miljarder av dem, i datorn ännu fler. TWith the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. In the pursuit of further improving the transistor structure and its performance new approaches are being evaluated. A very

Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices. In thi

Increasing global interconnectivity, in terms of our economies, ecological systems and population dynamics, can reduce or amplify the risks posed by climate change. The ongoing Coronavirus 2019 crisis demonstrates how rapidly disasters and risks can cascade and escalate across countries to become a shared problem globally. Climate change impacts are increasingly being recognised not only as a nati

A system for affective touch has been constructed, in a study of humanoid and social robotics. The system detects, processes and analyses signals from touch, identifies touch types, and provides a corresponding emotional response and expression. Touch is detected on an Epi humanoid robot head through the use of conductive paint on the inside on the head shell, and the electrical signal produced is

Bakgrund: Personer med psykisk ohälsa har ofta en nedsatt förmåga att bearbeta sinnesintryck. Tidigare har kopplingen mellan det individuella sättet att hantera sinnesintryck och olika sociodemografiska faktorer undersökts hos psykiskt friska personer, men studier gällande detta saknas för personer med psykisk ohälsa. Syfte: Att undersöka sensoriska bearbetningsmönster och deras eventuella kopplBackground: People with mental illness often have a reduced ability to process sensory inputs. Previously, the link between the individual way of dealing with sensory inputs and sociodemographic factors has been investigated in mentally healthy people, but there’s a lack of similar studies for people with mental illness. Aim: To investigate sensory processing patterns and their possible connecti

The aim of this thesis is to examine how archival institutions perceive their role in managing archives that contain witness testimonies from Holocaust survivors. Choices made by the archival institutions in regards of preservation, digization, ethics and availability to users are analyzed. Three archives are the focus of this research. The Polish Research Institute archive contains witness testim

When, how and why does farming become capitalist? This question has long shaped debates in agrarian studies and economic history. Although traditional analyses emphasize market dependency and competitive pressures, this paper argues for a shift in focus towards the diverse strategies of reproduction that farmers have employed in different historical contexts. Rather than searching for common capit

In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from th

Studiens syfte var att undersöka psykoterapiavslutningar i åldern 15-18 år utifrån faktorer som har betydelse för avslutningen och hur separationsaspekten kan bearbetas i samband med denna. Forskningsansatsen utgick från ett hermeneutiskt och fenomenologiskt perspektiv med Tematisk analys som metod. Sammanlagt gjordes åtta intervjuer med barn- och ungdomspsykoterapeuter. I studien identifierades s

Two different techniques exist for glass fiber production, direct melt bushing and marble bushing. The purpose of the project was to study the glass fiber production process and investigate the possibilty of constructing mathematical models from experimental data. This part also included implementation of a DAQ system to obtain the expeimental data. A second objective was to construct an efficent

The aim of our study was to investigate the image the Swedish media present of cannabis and in particular hasch. We gathered all articles published during one month in the year 2002 and in 2012 in three major newspapers in Sweden. The newspapers examined where Dagens Nyheter, Aftonbladet and Metro. Through a social constructive perspective and discourse analysis as method we divided the content in

This bachelor thesis studies the process of the culture and arts economic support system in the municipality of Lund. It aims to define problems concerning the current support system, which in the present situation appears in form of a stagnant cultural eco system. To do this participant observation have been used as a method and interviews and communications analysis as complementary methods. The
