Background: Steroid injections are used in idiopathic carpal tunnel syndrome (CTS), but evidence of efficacy beyond 1 month is lacking. Objective: To assess the efficacy of local methylprednisolone injections in CTS. Design: Randomized, placebo-controlled trial. (ClinicalTrials.gov: NCT00806871) Setting: Regional referral orthopedic department in Sweden. Patients: Patients aged 18 to 70 years with

The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. A special case of bubble transport is the cavitation phenomenon, which mainly has a negative effect on the performance of

Xylanases without contaminating cellulases are produced by a wide variety of aerobic bacteria and fungi but anaerobic organisms producing such enzymes are rare. Clostridial species viz., Clostridium beijerinckii LU-1, C. acetobutylicum LU-1, C. butyricum and C. bifermentans LU-1 isolated from rumen produced xylanase (E.C. 3.2.1.8) of 1.5-4.2 U/ml on oat spelt xylan as sole carbon source. Cellulose

BACKGROUND: Both chronic obstructive pulmonary disease (COPD) and tuberculosis (TB) primarily affect the lungs and are major causes of morbidity and mortality worldwide. COPD and TB have common risk factors such as smoking, low socioeconomic status and dysregulation of host defence functions. COPD is a prevalent co-morbid condition, especially in elderly with TB but in contrast to other diseases k

Clinical trials of pharmaceuticals have been running in Russia for more than ten years and while it is an attractive location for research, it remains a largely untapped resource as researchers look to expand patient recruitment outside the Western world. While academic sites like Moscow, St Petersburg and Novosibirsk have all gained experience in clinical trials, smaller hospitals in peripheral

The uncertainties and sources of variation in projected impacts of climate change on agriculture and terrestrial ecosystems depend not only on the emission scenarios and climate models used for projecting future climates, but also on the impact models used, and the local soil and climatic conditions of the managed or unmanaged ecosystems under study. We addressed these uncertainties by applying di

Pheromone communication systems have a reliable signal with a restricted window of amounts and ratios released and perceived. We propose a model based on a Gaussian response profile that allows a quantification of the response peak (location of optimum) and a measure of the peak width (response window). Interpreting the Gaussian curve, fitted by nonlinear regression (NLR), as a standard normal dis

This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th

Increasing demand for metals might lead to extraction of metals from materials, previously, thought of as waste. A letter by the Swedish Environmental Protection Agency and Geological Survey of Sweden from 2017 encouraged new and innovative waste treatments as well as recycling of waste produced in association with mining. The conventional treatment of acid mine wastewater creates large volumes of

Sweden faces an upcoming period where thousands of buildings built during the million program period will be in need of a façade renovation. There is a large energy-saving potential in these buildings, since they are often poorly insulated and often have a ventilation system without heat recovery. Performing energy-efficient renovation measures to a building are expensive, which results in that th

Mellan cirka 30-50 procent av den mat som produceras i världen årligen kommer aldrig människan tillgodo som föda. Att mat slängs eller på annat sätt går förlorad i livsmedelskedjan är ett stort problem, framför allt för att många människor i världen inte har tillgång till mat men också för att produktionen av livsmedel medför en betydande miljöpåverkan. Vad gäller statistiken över matsvinnet är de

Förlust av biodiversitet är ett av de största globala miljöbetingade problemen idag. Arter står inför ökande och potentiellt synergistiska hot från markomvandling och överexploatering av naturresurser, från globala såväl som lokala socioekonomiska krafter. Populationerna av ryggradsdjur har mellan år 1970 och 2016 visat på en global genomsnittlig minskning på 68 procent. Större djur, s.k. megafaunThe critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. Accurate numbers today are unknown, since the species is rare. Information indicates that less than 100 indi

Cell Death Detection in Images What if we could kill cancer cells? The fact is that we already can, at least to some extent. Many cancer treatments targets cancer cells and kill them by causing them to commit suicide. To be able to do this even better, and minimize adverse effects, information about the biological regulation behind cell death needs to be known, and far from everything has been di

Title: Adaptation of shipment consolidation and distribution network design to omni-channel retailing Authors: Johan Deniz, Martin Månsson Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Global retailers tend to have complex distribution networks. A part of the complexity stems from trade-offs in deciding

The main focus of this thesis is the analysis of the interactions between antennas and channels where electromagnetic fields play a central role. Our goal has been to devise a general framework to enable a clear separation of the properties of the propagation channel from the influence of the antennas at the same time as it provides a common ground for a joint characterization of their properties.

Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. Applications from both process automation, manufacturing, and robotics have been considered.

Sverige och Danmark anses i komparativa sammanhang tillhöra samma rättsfamilj. I arbetsrättsligt avseende skiljer sig Danmark från övriga nordiska länder på så sätt att man undvikit lagstiftning i mesta möjliga mån och t.o.m. överlåtit implementering av vissa EU-direktiv åt arbetsmarknadens parter genom kollektivavtal. Den lagstiftning som finns är spretig och i stor utsträckning införd p.g.a. EU-In a comparative context Sweden and Denmark are often considered part of the same families of law. In respect of labour law, Denmark differs from the other Nordic countries by avoiding legislation as much as possible and have even left implementation of some EU directives to be performed through collective agreements. The legislation is uneven and to a great extent introduced after demands from th

Environmental problems are a discussed subject in the world. The reason for this is that natural disasters are becoming more and more visible. EU is working to reduce the Union's contribution to the greenhouse effect. The goal is to reduce greenhouse gases with 20% by 2020 and 20% of the energy used should come from renewable energy sources. The EU’s Energy Performance of Building Directive (E

Vital societal functions and critical infrastructure rely to an increasing extent on services from space, such as navigation and positioning systems, timekeeping, and communications. However, understanding of space service dependencies is low among practitioners and society at large, with research on societal space dependency being limited as well. In order to avoid cascading effects from disrupti
