Två studenter, Safa och Jane, från kemiteknikprogrammet LTH har undersökt möjligheten att hantera hela reningsprocessen av spillvatten på Dow Chemical site i Landskrona genom att installera en pilotanläggning för nanofiltrering i anslutning till den redan befintliga ultrafiltreringsanläggningen. Dow i Landskrona framställer olika vattenbaserade bindemedel från akrylmonomerer och stora mängder vatDuring the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. The wastewater, that is treated currently by ultrafiltration (UF), contains different chemical residues such as surfactants, resid

I Sverige drabbas omkring 300 barn av cancer varje år och majoriteten av dem är bara fyra-fem år gamla när de får sin diagnos. Omkring två tredjedelar av barncancerdiagnoserna utgörs av leukemier, lymfom och hjärntumörer, medan den sista tredjedelen är olika solida tumörformer som njurtumörer och nervvävnadstumörer i buken. Cancersjukvårdens utveckling under de senaste årtiondena har medfört en avPurpose: The purpose of this study was to evaluate the impact of including PET (Positron Emission Tomography) in the process of pediatric radiation therapy planning. The aim was to study the effect on target volumes and how this in turn affects the resulting treatment plans. This study also aims to compare the estimated risks of various long-term complications and how the use of PET influences the

Eftersom Storbritannien efter mer än 30 år sedan CISG:s ikraftträdande fortfarande inte har anslutit sig till konventionen, frågan uppstår om varför så är fallet. Kan det vara så att det till en viss del kan bero på skillnader angående hur den engelska tillämpliga lagen ifråga och CISG ställer sig till skyldigheten att betala skadestånd? Syftet med uppsatsen är att klargöra de likheter och skillnaSince the U.K. after more than 30 years from the CISG’s enforcement still has not adopted the Convention, the question arises; how come? Could it be that this partially is due to differences in how the English applicable law and the CISG addresses liability for damages? The objective of this paper is to elucidate the similarities and differences in the two laws, regarding the seller’s obligation t

Stabilisering av urin för återanvändning av näringsämnen I naturen finns kretslopp för näringsämnen. När människan via avloppsvattenreningsverk släpper ut näringsämnen i vattendrag eller i luften bryts kretsloppen. För att bli en del av de naturliga kretsloppen behöver näringsämnena som människan avger återföras till jorden. Av: Marianne Olofsson Populärvetenskaplig sammanfattning av masteruppsaMunicipal wastewater contains a lot of compounds that could be seen as resources. Nitrogen, phosphorus and potassium are common ingredients in fertilizers and can all be found in wastewater. Nowadays only a small part of the nutrients found in wastewater are used on arable land. Urine contains the most of the nitrogen, phosphorus and potassium secreted by humans. Source separation of urine is a wa

This report presents the work developing a modular sailboat interior system that offers an easy and affordable way for recreational sailors to customize the interiors of their sailboats according to their different and changing needs. Cruising sailboats are like floating houses or cottages, with the difference that the interior is permanent. They have a long product life and often last for decade

The aims of this work were to evaluate objective and subjective signs of autonomic dysfunction (AD) in patients with primary Sjögren’s syndrome (pSS) and to evaluate its clinical associations. In study I, 46 pSS patients and 56/80/238 autonomic nervous function test (ANT) controls participated. Objective signs of AD were evaluated using three different cardiovascular ANTs and exocrine function in

Increased incidence and severity of Clostridium difficile infections (CDIs) is of major concern. However, by minimizing known risk factors, the incidence can be decreased. The aim of this investigation was to calculate the incidence and assess risk factors for CDI in our population. A 1-year prospective population-based nationwide study in Iceland of CDIs was carried out. For risk factor evaluatio

Neuroblastomas (NBs) are tumours of the sympathetic nervous system accounting for 8-10% of paediatric cancers. NBs exhibit extensive intertumour genetic heterogeneity, but their extent of intratumour genetic diversity has remained unexplored. We aimed to assess intratumour genetic variation in NBs with a focus on whole chromosome changes and their underlying mechanism. Allelic ratios obtained by S

Objective We tested whether men and women in the European Society of Hypertension (ESH) high normal and normal blood pressure (BP) categories, all included in the the Seventh Joint National Committee (JNC 7) prehypertension group, share similar metabolic characteristics and whether they differ from men and women with optimal BP (<120/80 mmHg). Methods BP (multiple measurements with a standardized

Background: Patients living under better socioeconomic circumstances often receive more active treatments after an acute myocardial infarction ( AMI) compared to less affluent patients. However, most previous studies were performed in countries with less comprehensive coverage for medical services. In this Swedish nation- wide longitudinal study we wanted to evaluate long- term survival after AMI

Background-Although the heritability of atrial fibrillation/atrial flutter (AF/AFl) has been determined, the familial risk in multiplex families is unclear. The main aim of this nationwide study was to determine the familial risk of AF/AFl in multiplex families. Methods and Results-We examined the familial risk of AF/AFl in the entire Swedish population. We linked Multigeneration Register data on

Molnens roll i klimatsystemet har studerats och deras påverkan på solens inverkan på jordens energibalans. Jordens albedo påverkar energibalansen genom att den påverkar hur mycket av solens instrålning som reflekteras eller absorberas. Moln påverkar jordens albedo och spelar därför en viktig roll i denna balans. Molnbildning sker till nära 100% i troposfären och där finns allt det vi kallar väder.The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. Cloud formation occurs almost 100% in the tropospher

Yogurt is an ancient food, used for a better preservation of milk. Milk gets fermented by Streptococcus thermophilicus and Lactobacillus bulgaricus (lactic acid bacteria, LAB) which converts the lactose present in the milk to lactic acid. These probiotics support the microbial population balance of the gastrointestinal tract. Sweet potato, Ipomoea batatas, is an important security crop in developi

Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. In a clinical setting, usually around 10 mL of blood can be col

The basin of the Poopó Lake, situated on the Bolivian high plateau, is severely contaminated by the mineral extraction and processing activities within the area. Many rivers in the area contain high concentrations of arsenic, lead and cadmium both in the water and the sediment phase. Moreover, huge amounts of mineral waste are situated in the area. In this study the environmental conditions of thr

For more than 30 years polyimides (PA) have been one of the main polymers for the fabrication of thin film composite membranes. Several researchers have assessed the main fabrication variables that influence the final structure of the polyamide layers including monomer concentration, solvents, additives in aqueous and organic phases and type of support to mention few [1,2]. However, few studies ha

Summary: In this population-based study, we compared the incidence of distal radius fracture in 2016 with that in the same region’s adult general population in 2001 using radiographs to identify fracture cases. We showed that the incidence decreased by 24% in 2016 compared with 2001 indicating an important development. Introduction: We conducted an epidemiological study on residents of northeaster

Aims: Obesity is a risk factor for several cardiovascular diseases (CVDs), including atrial fibrillation (AF). However, it is less clear whether overall fat or abdominal fat distribution are most important for risk of developing AF. This study investigates how different anthropometric measures correlate to the risk of developing clinical AF in the Malmö Diet and Cancer cohort (MDC-cohort). Methods

Objective: The aim was to describe the microbiology of surgically treated infective native (mycotic) aortic aneurysms (INAAs), and associated survival and development of infection-related complications (IRCs). Methods: Data were pooled from 2 nationwide studies on surgically treated patients with INAAs in Sweden, between 1994 – 2016. Patients were grouped and analyzed according to culture results:
