The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be
I övergången till en cirkulär ekonomi använder industrier i allt högre grad återvunnet material för att minska klimatpåverkan från sina produkter. Den ökade efterfrågan på återvunnet material drivs av både EU-direktiv och konsumenters preferenser. Både flask- och polyesterfiberindustrin ser potential i att möta EU:s krav och konsumenters efterfrågan genom att ersätta jungfruligt material med återvIn the transition towards a circular economy, industries are increasingly adopting recycled materials to decrease the climate impact of their products, driven by both regulatory requirements and consumer demand. The bottle and polyester fiber industries both recognize the potential to comply with EU policies and consumer preferences by replacing virgin material with recycled PET. Due to its desira
The rapid advancements of Artificial Intelligence (AI) in recent years have reshaped markets globally, urging companies to keep up with the development to maintain competitiveness and capture first-mover advantages. Although AI adoption is increasing across sectors, it has been found that Swedish companies lag behind other countries, such as the US and China. A key challenge identified is the lack
Certain organic micropollutants and emerging contaminants are increasingly detected in wastewater effluents due to enhancement of detection techniques and new technological processes or household items being introduced. Some of them can accumulate in food chains and/or pose health risks for humans, wildlife and ecosystems. Often, these are very difficult or impossible to sufficiently remove using
This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty. One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the s
Unsafe food consumption is an alarming issue worldwide which is linked to the fatalities of two million people annually. Such unsafe food intertwines with the right to health of consumers in a way that every individual is ubiquitously a consumer at one point in their life and safe food is one of the determinants of the right to health. Hence, the right to safe food and the right to health of consu
The present Comite´ Europe´en de Normalisation (CEN) and International Organization for Standardization (ISO) standards for safety, protective and occupational footwear EN ISO 20344–20347 classify footwear as cold protective by a pass/fail test where the limits are set for an allowed 10 °C temperature drop inside the footwear during 30 min at a temperature gradient of ~40 °C. It is questionable if
Since 2001 there has been an increase in oil price and unlike other times there is nothing indicating a major persistent decline. As oil is a limited resource and since current production capacity can not fully meet the growing demand the price on oil is kept high. A high oil price will not only result in higher price on fuel and thereby a higher cost of transport. It will also affect areas such a
The project was performed for FAS Converting Machinery AB (FAS) in Ystad with supervision from Industriell Elektroteknik och Automation at LTH. FAS is a company that makes machines for producing plastic bags on a roll. The problem given was to develop a sensor for detecting the perforations in the bags to ensure that the correct amount of bags was rolled up and that the tearing was in the right pl
In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced accor
In a world where technical knowledge gets outdated in an ever increasing speed, it is important that engineering education provides students not only with broad technical competences but also with so-called soft skills such as communications skills, leadership skills and team-working skills. When it comes to team-working skills, group projects have become an inevitable part of most LTH programs. L
Wild birds, particularly duck species, are the main reservoir of influenza A virus (IAV) in nature. However, knowledge of IAV infection dynamics in the wild bird reservoir, and the development of immune responses, are essentially absent. Importantly, a detailed understanding of how subtype diversity is generated and maintained is lacking. To address this, 18,679 samples from 7728 Mallard ducks cap
Objective: To explore the association between administration-to-birth interval of antenatal corticosteroids (ACS) and survival in extremely preterm infants. Design: Population-based prospective cohort study. Setting: All obstetric and neonatal units in Sweden from 1 April 2004 to 31 March 2007. Population: All live-born infants (n = 707) born at 22-26 completed weeks of gestation. Methods: The rel
Background: Novel efficacious treatments with long-term tolerability are needed for transplant-ineligible, newly diagnosed multiple myeloma (NDMM) patients. This phase 2 study evaluated the safety and efficacy of all-oral ixazomib-cyclophosphamide-dexamethasone (ICd) followed by single-agent ixazomib maintenance. Patients and methods: Patients were randomised (1:1) to receive 4.0 mg of ixazomib, 3
BACKGROUND: Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use
Background: Although reduced lung function is associated with both COPD and coronary events (CE), the pattern of lung function impairment could be different for the two outcomes. We examined different measures of lung function in relation to incident COPD events and CE in a population-based cohort. Methods: Baseline spirometry and lung clearance index (LCI) were assessed in 672 men aged 55 years.
Natural wetlands constitute the largest and most uncertain source of methane (CH4) to the atmosphere and a large fraction of them are found in the northern latitudes. These emissions are typically estimated using process ("bottom-up") or inversion ("top-down") models. However, estimates from these two types of models are not independent of each other since the top-down estimates usually rely on th
Propolis is a resin-like material produced by bees from the buds of poplar and cone-bearing trees and is used in beehive construction. Propolis is a common additive in various biocosmetics and health-related products, despite the fact that it is a well-known cause of contact allergy. Caffeic acid and its esters have been the primary suspects behind the sensitization potency of propolis-induced con
Background and study aimsEndoscopic submucosal dissection (ESD) is an established method for en bloc resection of large non-pedunculated colorectal lesions in Asia but dissemination of ESD in Western countries is limited. The aim of this study was to evaluate the role of ESD in the management of malignant non-pedunculated colorectal lesions in a European center.Patients and methods Among 255 patie
Smoldering multiple myeloma (SMM) is an asymptomatic precursor state of multiple myeloma (MM). Recently, MM was redefined to include biomarkers predicting a high risk of progression from SMM, thus necessitating a redefinition of SMM and its risk stratification. We assembled a large cohort of SMM patients meeting the revised IMWG criteria to develop a new risk stratification system. We included 199
