Introduction: Peritoneal carcinosis (PC) is the third common site of metastatic colorectal cancer which characterized by a very low survival rate. Surgical trauma has been identified as an important factor in the progression of PC, postulated to be caused by the inflammatory response to tissue injury. The mechanism behind tumor metastasis remains poorly understood. However, existing evidence indic

This article presents a shared vision among stakeholders across the value chain on the use of radio positioning and sensing for road safety in the 5G ecosystem. The key enabling technologies and architectural functionalities are explored, focusing on the extremely stringent localization and communication requirements. A case study for joint radar and communication using experimental data showcases

This thesis compares Auto Regressive Moving Average (ARMA) and Generalized Auto Regressive Conditional Heteroscedacity (GARCH) models for three metal commodities. ARMA models have an unconditionally non-random and constant variance, which typically serves well in effectively representing homoscedastic data. The GARCH models feature variable variance that is non-random when conditioning on the past

A Circular Economy (CE) calls for the value of materials and products to be maintained and recovered through narrowing, closing, and slowing loops. However, there remain challenges in moving up the waste hierarchy and not only recycling materials from products, but also capturing value through reuse of components in refurbished and repaired products. In this paper, we examine the practice of “harv

In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities. Moreover, new applications such as eHealth, autonomous vehicles, and c

The aim of this study is to gain an understanding of the potential relationship between populism and a population’s search for security and belonging. Furthermore, how this is expressed through the rhetoric and policies of a country’s leader, Recep Tayyip Erdoğan in Turkey, and Viktor Orbán in Hungary, this is examined through conducting a qualitative content analysis. Here I use newspaper article

Electromagnetic waves are widely used in society today for a multitude of applications. Design of electromagnetic devices and applications requires accurate methods for evaluating performance, which often means modern computational methods. While these methods have seen tremendous development in recent decades, it is still very important to perform measurements to validate the performance of devic

OBJECTIVES: This study clarified the exposure-response relationships for the organic acid anhydrides (OAA) hexahydrophthalic (HHPA) and methylhexahydrophthalic (MHHPA) anhydrides and the development of specific immunoglobulin (IG) E and G antibodies and work-related symptoms. METHODS: In an epoxy resin-using factory, air levels of OAA were determined by gas chromatography-mass spectrometry. Occupa

Using the Swedish Medical Birth Registry (MBR), obstetrical and demographic information was retrieved for 250 children with autism or Asperger syndrome who were born in Malmoe, Sweden, and enrolled at the local Child and Youth Habilitation Center. The reference group consisted of all children born in Malmoe during 1980-2005. Obstetric sub-optimality (prematurity, low Apgar scores, growth restricti

Prehistoric population structure associated with the transition to an agricultural lifestyle in Europe remains a contentious idea. Population-genomic data from 11 Scandinavian Stone Age human remains suggest that hunter-gatherers had lower genetic diversity than that of farmers. Despite their close geographical proximity, the genetic differentiation between the two Stone Age groups was greater tha

Polyurethanes and polycarbonates are widely used in a variety of applications including engineering, optical devices, and high-performance adhesives and coatings, etc., and are expected to find use also in the biomedical field owing to their biocompatibility and low toxicity. However, these polymers are currently produced using hazardous phosgene and isocyanates, which are derived from the reactio

The grocery market in Sweden is mainly divided between six different retailers who together have some 95% market share. The rest of the market is divided between thousands of different actors, selling groceries in other ways than the main retailers. This 5% market is interesting to investigate and the purpose is to identify the opportunities and barriers for those alternative food distributers. B

The phase center is defined as the point on an antenna from which the far field radiation seems to originate. Phase center calculations are often uncertain and vague, and very little concrete information is available on the subject. Recently, a replacement parameter called the radiation center was introduced in [5]. The radiation center is more rigorously defined than the phase center and possesses a

Marine macroalgal (seaweed) polysaccharides are highly promising for next-generation applications in several industries. However, despite the reported comprehensive potential of these polysaccharides, commercial products are scarce on the market. Seaweed cultivations are increasing in number and production quantity, owing to an elevated global trend of utilization interest in seaweed. The extracti

Traditionally, international humanitarian organisations have used on-demand dispatch of disaster relief goods from regional logistics units (RLUs) for sudden onset disaster response. This paper investigates the improvements in efficiency and resilience of disaster relief operations by combining the existing method of onshore prepositioning of relief items in RLUs with offshore prepositioning of re
