Caldicellulosiruptor species are regarded as the best microorganisms to produce hydrogen due to their ability to break down many types of sugars and hydrogen yields near the theoretical maximum. The major drawback is their low volumetric hydrogen productivity (QH2), which makes the current process setup economically non-viable. In this study, the natural capability of Caldicellulosiruptor species
Denna kvalitativa studie har haft som syfte att förstå hur den globala kampanjen #metoo har påverkat intervjupersonerna och deras inställning till sexuella övergrepp. Avsikten med #metoo har varit att uppmärksamma omfattningen av kvinnors utsatthet för sexuella övergrepp. Tidigare undersökningar och statistik visar på ett stort mörkertal när det kommer till offer för sexuella övergrepp och det är
Rapsfält – ett överflöd av mat eller en gul öken för vilda bin? Gula rapsfält har blivit en allt vanligare syn under försommaren i Sverige, ett hav av gula blommor rika på både pollen och nektar. Samtidigt går det allt sämre för de vilda bina världen över och många frågar sig om inte raps kan tänkas hjälpa de vilda bina på traven att förhindra att bina blir ännu färre. För utan bin förlorar vi enPollinators are important for both the agricultural landscape and natural areas, but currently many pollinator groups are declining. Pollinators have a strong relationship with plants, which humans long have benefited from. Nowadays, 35 % percent of the human food production somehow relies on animal pollination. Therefore, unravel the details about crop pollination and its relationship to differen
The study was carried out to identify critical factors for processed fruit shelf life in Tetra Recart packages. To investigate the importance of package volume and headspace volume, vitamin C was chosen to be the indicator. Oxygen in headspace, headspace volume, dissolved oxygen in product, oxygen transmission rate (OTR) and the concentration of vitamin C along storage time were measured to unders
The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. necator as it can be grown using C
The effects of monetary union on the trade of member countries have been debated. Economists have suggested that monetary unions can significantly increase trade with other member countries in the monetary union and even outside it. This thesis investigates the Swedish membership in the Scandinavian Monetary Union (SMU) from 1875-1910. Using collected data and a tailor made data set on the bilater
Syftet med detta arbete var att med utgångspunkt i teori rörande employer branding, personlighetsdraget extraversion och könsskillnader undersöka hur viktiga olika aspekter av employer branding anses vara. En kvantitativ studie utfördes för att undersöka detta. Datainsamling från sammanlagt 87 deltagare som alla studerar Personal- och arbetslivsfrågor vid Lunds Universitet, analyserades avseende gThe purpose of this study was to, with basis in theory regarding employer branding, the personality trait of extroversion and gender differences examine the perceived importance of different aspects of employer branding. A quantitative study that included a questionnaire was made to investigate this phenomenon. Data acquisition from a total of 87 participants, who all currently study the Human Res
There has been a dramatic growth in organizations aiming to leverage the power of platform business models and capture the vast amounts of value stemming from external innovation. Thus, actors are required to open up their innovation processes to third-party developers, and make sure these external resources are incentivized to both enter and remain in the ecosystem. So far, there has been a limit
Biomass-fired combined heat and power (CHP) plants in Sweden are usually equipped with a flue gas condenser, where the flue gas is sprayed with water which absorbs contaminants and makes the flue gas meet emission restrictions. This results in a contaminated condensate that has to be treated to be discharged or re-used in the plant. This can be done in various ways, but at the moment the interest
Self-awareness is the ability to recognize oneself as a distinct individual from others. For a long time, this was thought to be a uniquely human capability. However, in the last 50 years, it has been argued that humans might not be the only self-aware organisms and different tests have been developed to investigate this. The most commonly used experiment to test self-awareness is the mirror self-
The transport sector is one of many markets facing new challenges in the pursuit of reduced greenhouse gas emissions. The people at Volvo Powertrain in Malmö are continuously working to develop new and improved techniques that are able to live up to the ever-increasing legislations. A well performing turbocharger is an essential part of the combustion engine in order to reduce the fuel consumption
This thesis investigates how waste management in the Netherlands and the United Kingdom, as a long-term complex socio-technical change process, fits in the multi-level perspective designed by Geels (2002). Due to shrinking quantities of waste that is generated in the Netherlands, the combined heat and power plants are experiencing production overcapacity. Therefore, its importing waste from the
De senaste decennierna har allt fler aktörer pekat på att utveckling och rättigheter är starkt sammankopplade och därmed börjat anamma olika former av en Right Based Approach(RBA) till utveckling. Brist på utveckling kan ha sin grund i diskriminering. En grupp som halkat efter och som är strukturellt underordnad är kvinnor. En världsdel med hög andel fattiga är Afrika. Där finns det också en feminThe last 20 years diverse actors such as states, NGOs (Non-governmental Organizations) and IGO:s (Intergovernmental organizations) have adopted a Right-based Approach to Development(RBA). The main reason for adopting this approach is since development and rights are inter-connected. Discrimination is one cause for lack of rights and poverty. One group in an extra vulnerable position in poverty and
Följande rapport behandlar Östgötateatern i Linköping och skrivs som en del av kursen Brandteknisk Riskvärdering vid Brandtekniska avdelningen, Lunds tekniska högskola. Syftet med rapporten är att utvärdera personsäkerheten i byggnaden vid händelse av brand. Information om objektet fås genom ett platsbesök, varefter ett antal möjliga brandscenarion identifieras. Genom att utföra en grovanalys på d
Mitochondrial damage and dysfunction are associated with the aging process, and can be attributed to mutations in both nuclear and mitochondrial genes involved in cellular respiration. Mitochondrial DNA is particularly prone to damage due to its proximity to reactive oxygen species in the mitochondrial matrix. With the current advances in gene therapy studies for both inherited and acquired diseas
Industrial Internet of Things (IIoT) is part of the well-known IoT concept where a large number of devices need to be interconnected in order to collect and exchange data. Companies’ aim is not only to minimize cost during product design, operation and maintenance but also to enable remote monitoring on the efficiency of the devices-assets through the utilization of cloud services. Low Power Wide
