Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxicants but epidemiological findings are inconsistent. A cros

Critical infrastructure systems must be both robust and resilient in order to ensure the functioning of society. To improve the performance of such systems, we often use risk and vulnerability analysis to find and address system weaknesses. A critical component of such analyses is the ability to accurately determine the negative consequences of various types of failures in the system. Numerous mat

Previous research shows that men in preschool experience anxiety in physical interaction with children after media discourses about child sexual abuse in preschool. Against this backdrop this study investigates how male students and newly graduated preschool teachers talk about masculinity and physical interaction and how they experience that the preschool education offers them tools or discussion

The aim of this study was to examine pollution-induced community tolerance (PICT) of biofilm communities induced by chemical mixtures, characteristic of agricultural aquatic environments. Additionally, the use of biofilms as a natural passive sampler was investigated. In situ biofilms grown on artificial substrate for 4 to 6 weeks from sites located in agricultural areas were used to conduct a PIC

Saker klistrar, klibbar och fäster till varandra. Det har nog alla varit med om i olika aveseenden och situationer. Men vad är det egentligen som ger upphov till att visa saker, som lim eller klister, fäster mot varandra medan andra inte gör det? Och hur påverkar olika faktorer som temperatur, ytstruktur eller typ utav material hur mycket det fäster? Det här exjobbet är byggt runt ett fenomen somStickiness between materials can be a challening task when dealing with the complex interactions and processes related to packaging engineering. Part of the problem is that many factors like temperature, pressure, surface treatment as well as surface roughness all could play a part in contributing to the stickiness between materials. In this thesis a literature study has been done to map out poten

Limited-slip differentials (LSD) are normally placed in high-end and race cars to improve the handling, by reducing the differential speed and balancing the torque between the driving wheels. However, electrical-activated LSD struggles to continuously eliminate the differential speed over extended periods of time. To overcome this, BorgWarner proposed a dual-functional clutch pack, featuring two d

This report presents an innovative approach to industrial automation, focusing on the development of an automated system for erecting and filling cardboard boxes with wax jars. The project, executed in collaboration with Odigo Consulting and Scandinavian Hair Company (SHC), aimed to showcase enhanced production efficiency for small and medium-sized enterprises through the implementation of co

There is an increased demand for managing the complex hospital organisations in which healthcare personnel operate within, which is even more so evident from today's healthcare crisis in Sweden. Since the World Health Organisation (WHO) emphasised the importance of interprofessional collaboration in 2010, research on this area has increased. However, much of the research considers only one act

Connected to the ongoing global challenges relating to soil fertility loss and food security, there has been a recent upswing of alternative management practices (AMPs) within the agricultural sector. These methods are often focused on maximising soil health by safeguarding the below ground ecosystem and by increasing soil organic content. Consequently, AMPs tend to build resilience towards distur

Carbon dioxide removal (CDR) is quickly moving from mere imagination to material reality. As I write, billions of dollars are flowing into this nascent industry from government, philanthropy, and venture capital; this thesis thus attempts to grasp history as it flies. By employing a Marxist theoretical approach, including concepts like the real subsumption of nature and the spatiotemporal fix, I d

I denna rapport analyseras hur dimensioneringen av Rectiverter och UPS systemens storlek är anpassade för driftsplatsernas faktiska elförbrukning och vilka potentiella lösningar som finns för att effektivisera användandet av systemen för att minska elförbrukningen. Effektiviserandet av driftplatsernas system kommer att leda till en kostnadseffektivare anläggning. För svenska lågspänningsanläggningThis report analyzes how the size of Rectiverter and UPS systems is tailored to the actual electricity consumption at operational sites and explores potential solutions to optimize the usage of these systems in order to reduce electricity consumption. Optimizing the operational sites' systems will result in a more cost-effective facility. In Swedish low-voltage installations, a standard has be

Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. RIS aims to create favorable propagation conditions via programmable phase shifts. Employing RIS can

Purpose: The aim of this paper is to find out if the current accounting rules in IFRS 3 which mandate annual tests for goodwill impairment in line with IAS 36 add any information value for users on the Swedish stock market. Methodology: The paper is based on a quantitative research method with a deductive approach to interpret investigated samples. By using an event study, we have analyzed the e
