Mikroföroreningar är små molekyler som är restprodukter från t.ex. läkemedel, hormoner, kosmetika samt mikroplaster. Då majoriteten av dessa inte renas i våra av- loppsreningsverk har mikroföroreningarna börjat ackumuleras i vattendrag och dess negativa inverkan på vattenlevande djur har börjat uppmärksammas. En av metoderna för att ta hand om och avskilja mikroföroreningarna i reningsprocessen äThis thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. The effluent has been analyzed for total phosphorus (TP), total suspended solids (T

Kan geofysiska undersökningsmetoder vid undersökning av förorenade områden bidra till att uppnå en giftfri miljö? Sverige lider idag av stora mängder giftiga ämnen i marken som dumpats av olika sorters industrier under åtskilliga år, från en tid då ekonomiskt välstånd stod högt på agendan och okunskapen om miljön var utbredd. De här föroreningarna riskerar nu att skada både människors hälsa och mA central part of the risk assessment of contaminated sites is to conduct surveys of the area to assess the need for remediation. Through literature and interview studies this essay examined how geophysical methods can help to improve the environmental risk assessment of contaminated sites in Sweden. The results point to five main strengths in combining geophysical methods with the conventional me

Dagens ekonomi är ohållbar eftersom det leder till en överkonsumtion av råvaror och andra resurser. Den cirkulära ekonomin är en idé om hur ekonomi kan vara baserad på cirkulära principer. En av de viktigaste principerna är att samhället måste arbeta för att nå högre upp i avfallshierarkin, genom att främja återvinning och förebyggande av avfall. En av byggstenarna i cirkulär ekonomi är affärsmodeToday's economy is unsustainable as it leads to the over consumption of raw materials and other resources. The circular economy is an idea for an economy based on circular principles. One of the key principles is that society must work to reach higher up the waste hierarchy, and prosecution of recycling and waste prevention. One of the circular economy's building blocks are business models

Register allocation is one of the most critical parts of an optimizing com- piler. Although a great effort has been put into researching how to allocate registers, not much of it has been focused on vector registers. This report seeks to find out what fundamentally new problems arise when allocating vec- tor registers rather than scalar registers, how the previously known problems change in vector

This thesis investigates possible problems due to pressurization of high staircases. The main problem arising when high enclosures are not pressurized in sections in the event of fire is that an imbalance of the pressure profile in the building occurs. Pressure difference between the stairwell and adjacent rooms becomes large enough that the doors to the stairwell may be difficult to open and clos

Bomull är en huvudkomponent i majoriteten av kläder som tillverkas och har därför blivit ett standardmaterial i dagens samhälle. Bomull odlas på flera platser runtom i världen, men bomullsväxten kräver ett speciellt klimat, stora jordytor samt en enorm mängd vatten för att trivas. De här kraven har gjort att produktionen av bomull inte kunnat hålla jämna steg med den ständigt ökande efterfrågan påTextile fibres made from cellulose is a plausible candidate for replacing cotton in the future. In order to create textile fibres from cellulose the cellulose must first be dissolved and proceeded by regeneration through spinning. In this study mainly the solubility of regenerated cellulose has been investigated. Micro crystalline cellulose (MCC) was regenerated by dissolving it in NaOH (2 M) and

This master thesis explores the feasibility of using genetic algorithms in order to automate the process of optimizing hyperparameters for artificial neural networks (ANN). Today there is no standard way to optimize hyperparameters for ANN; often they are set manually by trial and error. In order to explore the feasibility of using genetic algorithms to optimize hyperparameters for ANN, two algori

Riskområden med snabb föroreningsspridning via grundvatten – grafisk illustration i ArcGIS Enskilda avlopp utpekas allt oftare som en betydande källa till spridning av förorenande substanser och patogener. Hur kan man identifiera och visualisera transporttider för föroreningar baserat på ett områdes geologiska karaktär? Idag finns cirka 700 000 hushåll med enskilt avlopp i Sverige varav hälften The raw water source lake Vombsjön is situated in the center of southern Scania and provides drinking water by artificial groundwater recharge for approximately 450 000 inhabitants each day. More than 2800 households within the catchment of lake Vombsjön treats their domestic wastewater with a decentralized sewer system. The configuration of these sewer systems varies, but it is common to have som

In ADB Safegate's airfield lighting product portfolio, two sizes of LED inset luminaires consist of similar internal components with different design. This project has investigated the possibilities to find generic design solutions for the internal components to fit both product sizes. By using modularized components the company will decrease the indirect costs of the product, for instance cos

The term Female Genital Mutilation is often used to describe a process whereby a part or all of the external female genitalia is been cut as a result of factors generally embedded around culture and tradition. This study takes a panoramic view at FGM beginning from a historical perspective when the practice was generally regarded as a cure to the sexual “excesses” of the female to the present day

Vad har kroppen för betydelse vid musikaliskt lärande? I en samhällsstruktur och akademisk tradition, där kroppen mer betraktas som ett transportmedel än som bärare av reell kunskap, ställs frågan i motvind. Denna studie ämnar i första hand undersöka idéstrukturer som omger vår syn på kroppens betydelse för och relation till musikaliskt lärande. Studien är inriktad på att via ett explorativt och What importance does the body hold in a musical learning experience? In a social structure and academic tradition, in which the body is more considered as a means of transport rather than as bearer of real knowledge, the question faces a headwind. This study mainly aims to investigate the preconceptions surrounding our view of the body's relevance and connection to musical learning experiences

Thesis Purpose The purpose of this research is to increase the understanding of occupational gender segregation by exploring how preschool teachers and principals perceive gender diversity, what they consider to be the primary issues that hinder men from entering this profession, and what they think a larger inclusion of men in the profession could lead to. Theoretical Perspective We based our re

The Jordanian state apparatus is increasingly limiting civil society in Jordan from engaging in open debate, and organisations are gradually inhibited from executing their activities and events. These are the premises on which this research is based, and in exploring them several questions arise. How can civil society in Jordan be characterised and applied? What do these obstacles look like in pra

Research Question: How do employees in Microsoft Denmark understand workplace inclusion? Methodology: Following an interpretive paradigm, we seek to explore in-depth understandings of employees in our case company. We conducted a multi-method qualitati

Säkerhet ses oftast som en del av en teknisk lösning vilket gör att företag har en tendens att dedicera mer resurser till teknisk säkerhet, snarare än strategisk säkerhet. Mänskliga faktorer kan ha en avgörande negativ roll för informationssäkerheten inom företag om grunden till informationssäkerheten inte hanteras på rätt sätt. Uppsatsen undersöker kopplingen mellan modellen CIA-triadens olika de
