Global pollinator populations are declining. One of the causes is land use change, which results in reduced flower resources in the landscape. Bumblebees have small stores of nectar and pollen and are therefore vulnerable to loss of flower resources. I test if forbs plantings, which enhance forage resources, can support colony development and reproductive success of bumblebee colonies in Californi

Breast cancer is one of the most common cancers in the world, and has therefore been widely researched the last decades. Breast cancer is one of the least aggressive cancer types, and this together with extensive research has given one of the highest survival rate of any cancer types. However, there is still a long way to go in order to decrease the number of deaths even further. New, more effecti
Dual-listing has become a popular approach for companies to seek funding and international expansion. Typically companies grow big from less developed domestic markets and march into developed markets. However, China, as an emerging market economy has witnessed a wave of Hong Kong-listed companies returning to the mainland for a second IPO. One primary assumption for companies’ motivation to retur
Vätgas är en energikälla som har en energidensitet (per massa) tre gånger så stor som naturgas. Detta gör så att vätgas är en huvudkandidat för morgondagens bränsle. Ett av de viktigaste forskningsområderna för vätgas innefattar produktion av vätgas eftersom det finns en stor mängd metoder för vätgasproduktion. Återvinnbar vätgas kan potentiellt produceras med vattenelektrolys, som undersöks i det
In Senegal, rice plays a crucial role in combating food insecurity since it is one of the most consumed staple crops. Despite this, national rice-production is insufficient in relation to the domestic demand, making Senegal one of West Africa’s most import-dependent countries in rice. To combat this issue, the Senegalese government aim to reach national self-sufficiency in rice production, primari

Popular Abstract in Swedish Energianvändningen i världen måste minska drastiskt inom en snar framtid för att därmed minska utsläppen av växthusgaser och bromsa klimatförändringarna. Energi och handlande med energikällor har även blivit nationella säkerhetsfrågor. Inom Europeiska Unionen används ungefär 40% av den totala energianvändningen i byggnader, vilket innebär ungefär 36% av det totala koldiThe use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. Passive houses are one way to reduce the energy use in buildings and at the same time keep a good indoor comfort. Th
The cyclopentanone and cyclopentenone group of fragrance ingredients was critically evaluated for safety following a complete literature search. For high end users, calculated maximum dermal exposures vary from 0.002% to 15.16% in hydroalcoholic products; systemic exposures vary from 0.0003 to 0.7122 mg/kg/day. The cyclopentanones and cyclopentenones had a low order of acute toxicity and no signif
The COST/IWA Benchmark Simulation Model No 1 (BSM1) has been available for almost a decade. Its primary purpose has been to create a platform for control strategy benchmarking of activated sludge processes. The fact that the research work related to the benchmark simulation models has resulted in more than 300 publications worldwide demonstrates the interest in and need of such tools within the re
Objective To determine the sensitivity and specificity of the 'ovarian crescent sign' (OCS) - a rim of normal ovarian tissue seen adjacent to an ipsilateral adnexal mass as a sonographic feature to discriminate between benign and malignant adnexal masses. Methods The patients included were a subgroup of patients participating in the International Ovarian Tumor Analysis (IOTA) Phase 2 study, which
The major histocompatibility class I (MHC-I) genes are highly polymorphic and the proteins that they encode play a crucial role in both the innate and the adaptive immune response. A MHC-I molecule consists of three parts, one polymorphic heavy chain, one invariant light chain, β2-microglobulin and a peptide of usually between 8-11 amino acids in length. The maturation and quality control of MHC-I
The Swedish needle exchange debate was revived when regulations for opening new needle exchange facilities were lightened 2017. Needle exchange has been debated over ever since it was introduced in the mid 80’s. With the contemporary debate as a premise the aim of this study was to see if the arguments for and against needle exchange has changed. The chosen method for the study was a qualitative c
Det finns många svårigheter med att tillverka livsmedelsprodukter som är emulsioner. Syftet med detta projekt var att utveckla en emulsion enligt krav som beställaren av produkten hade satt upp. En första utveckling av produkten skedde ungefär ett år tidigare, och den fortsatta utvecklingen baserades alltså på denna produkt. Det som hade blivit ett problem med den första utvecklade produkten var aIt is a difficult process to create a drinkable food product that is an emulsion. The aim with this project was to create one, containing ingredients on levels described by a customer. A product had been developed before, but resulted in a product that had viscosity that was too high, and the aim with this further development project was to keep the levels of the ingredients on a level according t

Drastic emission-reductions are needed to avoid the disastrous consequences of climate change. Flying is one of the highest individual carbon-impact actions. By 2050, the aviation industry’s share on global greenhouse gas emissions is expected to rise by 300 to 700%. An intervention to counteract this development is to reduce flying at universities as they have a critical role in leading sustainab
