Resultat från epidemiologiska studier har antytt att flavonolrik kakao sänker blodtrycket. Detta sker troligen genom att flavonoider i kakao leder till aktivering av eNOS som sedan katalyserar NO-syntesen i kärlendotel vilket leder till vasodilation och sänkt blodtryck. En nyare studie har funnit att kakao dessutom inhiberar enzymet ACE. Mycket tyder även på att NO-koncentrationen är kopplad till ACE-aktiviteten då dessa faktorer visat sig följa varandra inverst vid varierande doser. Det finns också ett samband mellan ACE-genotyp och serumnivåer av ACE.

I en allt st?rre utstr?ckning syns h?llbara designinitiativ p? modemarknaden. S?rskilt de initiativ som kallas resale, repair, recycle och upcycle. Inneb?rden av dessa h?llbara designinitiativ kan sammanfattas som att gamla material eller hela modevaror f?r f?rl?ngda liv genom att de f?r?dlas eller p? andra s?tt f?rb?ttras.

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

I en omv?rld d?r h?llbarhetsfr?gor f?r st?rre intresse ?r det av stor vikt f?r f?retag att l?gga ner resurser och tid p? att utveckla sina verksamheter h?llbart. ESG som st?r f?r ett f?retags arbete g?llande milj?-, social- och styrningsfr?gor har v?xt under senare ?r. Det har genom ?ren genomf?rts ett stort antal studier p? koppling mellan f?retags ESG-prestationer och deras finansiella prestationer som f?ljd, men resultaten ?r skilda och det finns inget tydligt konsensus inom ?mnet. I denna studie unders?ks sambandet mellan europeiska IT-f?retags ESG-betyg och deras finansiella prestationer.

Fertilitetsegenskaper har ofta låga arvbarheter och selektion baserat på fenotyp är ofta ineffektiv och långsam. För att förbättra fertilitetsegenskaper som ovulationsmängd och kullstorlek hos får är det effektivast att selektera avelsdjur utefter deras genotyp. Olika mutationer i gener tillhörande transforming growth factor-? (TGF?) superfamiljen har visat sig påverka ovulationsmängd och kullstorlek hos får. Dessa gener är BMPR-1B, BMP15 och GDF9.

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

Den h?r studien ber?r speciall?rares upplevelser och hantering av situationer d?r ett utmanande beteende hos en elev resulterat i akut hotfulla situationer d?r speciall?rare blivit skadade eller varit r?dda f?r att skadas fysiskt. Tidigare forskning visar att utmanande beteende ?r relativt vanligt hos barn med intellektuell funktionsneds?ttning. Utmanande beteenden kan ta olika for-mer d?r ett av de vanligaste ?r aggression, s? som att sl? eller sparka mot omgivningen.

Denna studie unders?ker den upplevda tryggheten hos kvinnor vid Fr?lunda Torgs sp?rvagnsh?llplats i G?teborg och identifierar en rad olika faktorer i den fysiska milj?n som p?verkar deras upplevelse. Med en feministiskt geografisk infallsvinkel och teoretiska ramar som inkluderar Broken Window-teorin, CPTED syftar studien till att bidra till en ?kad f?rst?else f?r hur Fr?lunda Torgs sp?rvagnsh?llplats uppfattas och kan utformas fr?n kvinnornas perspektiv. Genom semistrukturerade intervjuer, analyserar studien kvinnors upplevelser av trygghet och otrygghet vid sp?rvagnsh?llplatsen Fr?lunda Torg.

Ramsta Robotics är ett företag som ligger i Uppsala. Företaget grundades 1999 av tre uppfinnare. Man har utvecklat en robot, som används för att göra rent i djurstallar. Tvättarbetet har hittills gjorts helt manuellt med högtryckstvätt. I framför allt svinhus ärarbetsmiljön direkt hälsovådlig ? bland annat på grund av alla de kväveföreningar som löses ut när vattnet blöter upp anläggningen.

Climate change is a phenomenon that know no boundaries. While focus on environment and climate change has become highly prioritized, nationalism has spread across Europe. Nationalism is by many considered to refuse action to combat climate change although some argue that nationalism could combat global climate change. Previous research on how nationalism is implemented in environment and climate politics has mainly focused on single parties. The thesis therefore aims to give a broad approach and compare how nationalism is used in environment and climate politics by analyzing 4 European parties with either ethnic or civic nationalism and different roles in their party system. With a qualitative content analysis on party programs and election manifestos the findings imply that parties use nationalism in the climate and environment discourse in a variety of ways.

Invasive alien plant species have historically caused major damage to ecosystems and are considered to be amongst the greatest threats to biodiversity globally. The lurking threat of harm to well functioning ecosystems has led to the development of global and regional goals and regulations which seek to stop the spread of invasive species. The Swedish Environmental Protection Agency has proposed a list of species that are specifically harmful to the Swedish flora and fauna, which includes (amongst others) garden lupin. The management of invasive species is however largely dependent on local actions, making municipal public servants key players. This qualitative study uses interviews to investigate how municipal public servants who are responsible for managing invasive alien species view this work.

Forskning om lovverksamheten ?r begr?nsad trots att den ?r en viktig del av barns fritid och tid p? fritidshemmet. D?rf?r har vi valt att unders?ka hur l?rare i fritidshem talar om fritidshemmets m?jligheter eller begr?nsningar f?r kvalitet under loven, och hur kvalitet beskrivs av l?rare i fritidshem. Studien har sin utg?ngspunkt i en kvalitativ metod med semistrukturerade intervjuer f?r att besvara studiens tv? fr?gest?llningar: Hur beskriver l?rare i fritidshem verksamhetens kvalitet under loven? P? vilket s?tt anser l?rare i fritidshem att de strukturella f?ruts?ttningarna p?verkar fritidshemmets m?jligheter att erbjuda en meningsfull och kvalitativ verksamhet under loven? Studien bygger p? forskningsteorin: fyra dimensioner f?r pedagogisk kvalitet.

Sustainability and the role of companies in terms of emissions and environmental impact has become increasingly more relevant. In 2014, the EU decided to introduce the NFRD, a directive that makes it mandatory for companies that meet the requirements to report on sustainability. This thesis aims to examine how four large Swedish industrial companies report about sustainability in connection with the introduction of NFRD, looking at the years 2015 (2014), 2017 and 2022 from an environmental viewpoint. Furthermore, the study also intends to investigate how the companies write about their sustainability work, as actual achievements or what they have ambitions to do in the future. In order to carry out the study, a content analysis with elements of both qualitative and quantitative features has been used called the CONI method.

The transport sector is one of the biggest pollutants in the European Union. In relation to transport policies and environmental policies, intermodal transportation solutions are of high relevance to establish a sustainable transport sector for the future. Intermodality which is defined as smooth transition between transport modes is a key figure for how modal shares are divided between the modes of transportation. The aim of this bachelor?s thesis is to examine the research gap whether policies intended for a specific transport mode affects each other in relation to EU policies intended for intermodality.
