Animals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. Some insects such as the vinegar fly Drosophila melanogaster have develop
While urban areas are predicted to expand due to population growth, new approaches towards smart solutions in urban infrastructure and transportation are on the rise. With access to new technology, data has been given much attention from municipalities and decision makers. This thesis is interested in how the public sector will utilize the untapped potential of data collection, and what effects th
The use of artificial football fields has increased drastically in Sweden since a few years back. Moreover, approximately hundred new fields are created each year. The infill material, consisting of rubber granulate made of old tires, are classified as the second largest source of micro-plastic dispersion to the oceans. This study aims to investigate the spread of the rubber granulate from two art
Duni has successfully expand their business internationally. Internationalization makes the distance between the producer and consumers become longer and this leads to strength reduction of corrugated boxes along the supply chain. To overcome this problem, this study is conducted to find the extent of corrugated boxes strength reduction during logistical activities, practices and condition in the
Shared Reading is a reading promotion concept that originated in the United Kingdom and has, over the past three years, begun to engage various actors in Sweden including the Swedish hospital library. In the use of the method, health-promoting effects have also been identified, which is why Shared Reading has interested research in so-called medical humanities in a Swedish as well as an internatio
The vehicle industry is making great strides in electric and hybrid technologies, representing a significant step towards reducing emissions from personal vehicles. In order to make the transition to new hybrid technologies as convincing as possible, well-functioning and smooth transitions between traditional combustion engines and electric motors are required. So-called mild hybrids enable a cos
Migration to wintering grounds is a process that a large proportion of songbirds perform every year. It has been suggested that there are differences in the migration performance between adults and juveniles due to the experience the former have over the latter, after having flown this journey before. The aim of this study was to analyse age differences regarding activity, energy deposits and depa
Urbanisation in Beirut has led to a situation where the city suffers from a severe lack of green public space—Lebanon’s capital have ended up with some of the least amount of public green space per capita in the world. The lack of green surfaces and vegetation in Beirut contributes to the city’s Urban Heat Island (UHI)—a phenomenon where an urban or metropolitan area traps waste heat and end up si
In the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade
To reduce the risk of serious chemical accidents to occur there is a legislation called the Seveso-legislation. One part of this legislation demands that all business that handle certain amounts of chemical compounds to submit a safety report in order to get permission to run their business. The safety report should contain over-all plans of how to handle safety as well as detailed descriptions o
Abstract We studied the effects of UV-A radiation and predatory fish on mantle pigmentation of freshwater snails Radix balthica. The results showed that UV radiation and fish chemical cue induce larger ratios of pigmented area on mantle, respectively and when combined. UV radiation and predatory fish chemical cue seem to affect mantle pigmentation independently. The ratios (0~100%) of pigmented ma
In the E. ON sponsored research project, Distibution LABoratory, at the Department of Industrial Electrical Engineering and Automation at LTH the impact of the increased move towards use of cables in the Swedish distribution grid is examined. The project also built a model of a small distribution grid. The model was used to simulate a Petersen coil earthed grid system. Petersen coil earthing lower
Global demands for water continue to rise while at the same time, the availability of reliable water resources are deteriorating. As 70% of the world’s human consumption of water resources is directed towards agricultural production, the need to improve water use efficiency and sustainability in these areas is of utmost importance. In order to tackle these issues, the concept of “Integrated water
Background The fierce competition in the telecom industry makes operators heavily invest in acquiring new customers. This is most often done with marketing campaigns and subsidies of handsets. But to be truly profitable, it is crucial not only to attract new customers, but also to make sure they retain with the company for as long time as possible. This turns the mobile operators’ attention to cus
Thesis purpose: In order to contribute to Consumer Culture Theory, as well as critical dimensions in the foodie literature namely authenticity, democracy/distinction and gender, the study’s aim is to explore how discourses and socio-cultural meanings underlie identity constructions in the specific sourdough culture. Theoretical framework: As no research addresses the sourdough phenomenon directly
The construction sector is often criticized for its lack of efficiency and quality.When the construction industry is compared to the rest of the domestic manufacturing industry, the general conclusions of the industry’s low efficiency is confirmed. The purpose has been to clarify why there is no sustainable building, despite the well-developed technology that now is available. The report also exam
There are about eight thousand and five hundred of level crossings in Sweden according to Swedish Transport Administration (STA). Approximately four thousand and six hundreds of railroad crossings are arranged without any type of protection. Most of the accidents occurs when there are none protection or the amount of traffic is very low. Types of protections that are usually used in most of the le
Wireless Power Transfer (WPT) is increasingly utilized across various practical domains, requiring continual development and optimization of supporting technologies. An essential aspect of this progress is the efficient testing of WPT Systems. This thesis explores optimization of the testing process using Machine Learning(ML) and data analysis, applied on historical data represented by test outcom
Tissue shortage for lung transplantation remains a problem worldwide as lung transplantation is often the only available option with numerous possible complications. Generating lung tissue ex-vivo has been proposed as one way to potentially overcome this shortage. For this, tissue engineering is one potential strategy to either repair, replace or regenerate damaged tissue and organs. In this thesi
