The assessment of remediation on metal-polluted soils is usually focused on total and/or bioavailable metal content. However, these chemical variables do not provide direct information about reductions in heavy metals pressure on soil microorganisms. We propose the use of bacterial communities to evaluate the efficiency of three remediation techniques: crushed mussel shell (CMS) and pine bark (PB)
Asynclitism, the most feared malposition of the fetal head during labor, still represents to date an unresolved field of interest, remaining one of the most common causes of prolonged or obstructed labor, dystocia, assisted delivery, and cesarean section. Traditionally asynclitism is diagnosed by vaginal examination, which is, however, burdened by a high grade of bias. On the contrary, the recent
A supercritical fluid extraction methodology was used to extract flavoring and bioactive compounds from truffles. Some parameters such as CO2 flow rate (1–3 mg/mL), extraction time (15–90 min) and different trapping food matrices (grape seed oil, gelatin, agar agar and water) were optimized using response surface methodology to enhance extraction and trapping yields. The optimal conditions (2.27 m
The objective was to investigate if diffusing laser fibres can be modelled as conductive heat sources without miscalculating coagulated volumes, and if finite element analysis, disregarding light transport, may be used for three dimensional (3D) treatment planning in interstitial laser thermotherapy (ILT). Temperature distributions and coagulated volumes with a diffusing laser fibre, as compared t
We present spatially and spectrally resolved emission from nanowires with a thin radial layer of GaAs embedded in AlGaAs barriers, grown radially around taper-free GaAs cores. The GaAs layers are thin enough to show quantization, and are quantum wells. Due to their shape, they are referred to as quantum well tubes (QWTs). We have investigated three different nominal QWT thicknesses: 1.5, 2.0, and
Prostate specific antigen (PSA) in serum has recently been shown to occur in complex with alpha 1-antichymotrypsin and as an approximately 30 kDa. noncomplexed molecular form. We characterized PSA by 3 different assays in samples from 144 patients with benign prostatic hyperplasia (BPH) and 121 with carcinoma of the prostate. One of these noncompetitive assays measured total PSA by detecting PSA c
Analysarbetet av finansiella data i samband med prognostisering blir snabbt omfattande, både ur ett teoretiskt och ur ett empiriskt perspektiv. Prognosteorierna står mot varandra. Är marknaden starkt effektiv eller finns det prognosmöjligheter? Att genomföra en empirisk prognosstudie resulterar snabbt i krävande beräkningsintensiva prognosmodeller. Då prognoser för flera tidpunkter behövs så måste

This study makes a numeric and visual comparison of two different multibeam echo sounding (MBES) surveys performed at the exact same location, in an effort to establish how reliable and comparable the vertical depth measurements are. The horizontal position uncertainty is not issued in this study. The analysis was performed on data delivered by two survey contractors, The Norwegian Coastal Admini
In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var
The purpose of this study is to examine the optimal hedge ratio for the currency exposure of foreign investments. The optimal hedge ratio is determined after evaluating our portfolios from the three perspectives; ex-ante, ex-post and profit/loss. The ex-ante perspective is examined by the usage of historical simulation to calculate VaR on 11 portfolio pairs. Each pair consists of a portfolio with
Abstract Background Axis Communications is a Lund based company which specializes in network cameras. In addition to the cameras, the company has a wide range of accessories that ensure their customers receive complete solutions. While the company has had significant successes by investing heavily in R&D, increased competition from low-cost competitors is now placing higher demands on cost-eff
Trots att preventivmedel är lättillgängligt för kvinnor i Sverige idag, både praktisk och ekonomisk, visar nyligen framlagd forskning att abortstatistiken i Sverige ökat bland kvinnor 24-29 år. Studien lyfter fram negativa attityder gentemot hor-monella preventivmedel som en bidragande faktor. Vår studie ser till hur missupp-fattningarna kring preventivmedel kan förklaras, vilken roll kommunikatioEven though contraceptives in Sweden are made sure to be easily accessible to women both practically and economically resent research by medical institutions in Sweden shows that the abortion statistics are increasing amongst women aged 24-29. The study implicates that the statistics are related to negative attitudes to-wards hormonal contraceptives amongst these women. In our study we aim to in-v
In the spring of 2015, five young feminist activists were arrested by the Chinese police for allegedly ‘causing trouble’, which resulted in global attention aimed at this new wave of feminist movement. Youth feminist activism have made their voice heard in China through numerous actions for gender equality since 2012. Not much is known about the new feminist movements and the limited work that exi
Preterm birth is a leading cause for birth complications and neonatal mortality in the world. It remains difficult to predict whether a preterm birth will occur, which hinders the possible use of prevention treatments. This thesis investigates the use of machine learning models in the prediction of spontaneous preterm birth. In addition, possible heterogeneous performance of these models among dif
Larvae from the non-biting midge family Chironomidae have previously been demonstrated to be sensitive to environmental pollution in aquatic environments. Exposure to different contaminants has resulted in an increasing occurrence of deformities of the mouthparts in the larvae. Common pollutions which induce mouthpart deformitys are metals (such as Pb, Zn, Cd, Cu, Hg, Cr, Ni), pesticides and some
The purpose was to investigate "adult foster childrens" view on their childhood and how it may have been influencing their adulthood. The importance of relationships were mostly in focus in the essay. The method was qualitative deepinterviews with three adult foster children between 30-42 years of age. Important themequestions was about: origin family, the time in foster home, relations
We have done a study concerning young women, in the ages of 20 to 30, and their thoughts about, consumption of, and habits regarding alcohol. The study is the base of our essay which has been done during the last ten weeks of the sixth semester (of seven) for the Bachelor degree of Social Work Science at Socialhögskolan in Lund. The study is built around five themes found in the essays purpose. El
