Large seeds are assumed to have higher probability of successful recruitment than small seeds. This is because larger seeds give rise to larger seedlings and larger seedlings better withstand environmental hazards like deep shade and drought. Biotic and abiotic limitations to seedling growth and survival, and conversely availability of safe sites for recruitment, vary along environmental gradients
The African continent has been severely affected by the HIV and AIDS pandemic and as a consequence, development is being obstructed. Agriculture and food production systems are changing as a result of the burden of the pandemic. Many farming families are experiencing trauma from morbidity and mortality as well as facing labour losses and exhaustion. To further exacerbate the situation, climate var
Many plants are adapted to an eroded landscape with a large proportion of virgin soil. Open and disturbed soils are today almost only restricted to agricultural fields with high loads of fertilizers. We conducted a pot experiment in order to investigate growth and nutritional constraints of one calcicole species, Anisantha (syn. Bromus) tectorum, and one calcifuge species, Rumex acetosella, in dec
In this article, we review recent theoretical work that has complemented the extensive experimental data available for multicopper oxidases (MCO) and led to the elucidation of the reaction mechanism of this class of enzymes. The MCOs couple four one-electron oxidations of substrates at the mononuclear type 1 copper (Cu-T1) site with the four-electron reduction of dioxygen at the trinuclear copper
The large international variation in the incidence of prostate cancer (PC) is well known but the underlying reasons are not understood. We want to compare PC incidence and survival among immigrants to Sweden in order to explain the international differences. Cancer data were obtained from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for PC in first-degree immig
Algoritmiska rekommendationer har blivit allt mer förekommande i vardagen. Från filmer, musik och potentiella partners till söta katter och roliga danser – sociala medieplattformar utvecklar kraftfulla algoritmer för att förutsäga vad användarna kommer tycka om och behöva. Algoritmiska rekommendationer föreslår dock inte samma innehåll till alla användare, utan anpassar sina rekommendationer dynamAlgorithmic recommendations have become ubiquitous in everyday life. From films, music, and potential partners to cute cats and silly dances, social media platforms develop powerful algorithms to predict what users might like and need. However, algorithmic recommendations do not suggest the same content to all users but instead adapt their recommendations dynamically through endless feedback loops
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spa
Every single child has the right to a childhood as well as a future. The labor regulations within the international conventions exist in order to make sure that these rights are looked after, but the ratification of the conventions is just the beginning. In order to receive the results which are set by the conventions, it is crucial that the implementation is successful. The politics of the countr
Presence of lactic acid bacteria on a beer brewery The purpose of this thesis is to help a brewery solve a mayor problem regarding the quality of their product. The brewery has for a considerable amount of time had a problem with the presence of lactic acid bacteria in their product, which has caused it to acid long before the expiration date has passed. The root of the problem could be establishe
Letters of credit is an instrument of payment that is frequently used in international trade. Normally the buyer engage a bank which irrevocably promise to pay the seller when the seller (beneficiary) present a specific set of documents. The document’s purpose is to prove that the seller has fulfilled the obligation in the underlying contract of sale. The bank’s task is to investigate the document
Sustainable development is now a part of environmental, social, and economic agendas all over the world. Sustainability projects are cropping up in urban areas, including projects in the housing sector aimed at sustainable regeneration. Simultaneously, it is now recognized that public participation is an essential character of implementing change. And within sustainability participation, it is con
When grief finds new ways - a qualitative study about grief blogs The purpose of this study was to examine why people who suffer from grief chooses to share their experiences through blogs on the Internet. Furthermore and by studying the blogs we intended to gain understanding of the advantages and disadvantages that blogging can bring to the bloggers. The study is based on a qualitative analysis
This paper investigates the last two months of the Vietnam War, March and April 1975, from the CIA:s perspective. During the last two decades, the CIA have declassified many documents about the Vietnam war, thus making new source material available. The withdrawal of American troops from Afghanistan and the subsequent Taliban conquest, has also sparked a renewed interest in the Vietnam war. Hence,
Replacement therapy with blood products has long been the only available therapeutic option for patients with bleeding disorders. Plasma-derived cryoprecipitate and factor (F) VIII concentrates, which have been used for hemophilia A patients, involve the risk of transmitting blood-borne diseases. Both plasma-derived and recombinant FVIII concentrates are expensive, and there is a global shortage.
Popular Abstract in Swedish Avhandlingen består av tre separata papper. De är alla empiriska studier som undersöker hur fragmentering av produktionsprocesser och globala utbudskedjor har påverkat internationell handel. Den första studien fokuserar på hur privata standarder i den alltmer globaliserade livsmedelsindustrin påverkar företags importbeteende. Genom att ge en kvalitetsförsäkran kan certThis thesis consists of three separate papers. They are all empirical papers that examine how fragmentation of production processes and global value chains have affected international trade patterns. The first paper focuses on how private standards in the increasingly geographically fragmented food sector affect firm-import behaviour. By providing a quality insurance for the imported good, certif
AIMS: To present descriptive data, study psychometric abilities, and investigate the characteristics of non-respondents to SF-12. METHOD: The study had a randomized sample (n=4278; age: 75-105) stratified in four age groups. Factor analyses were performed to investigate the factor structure of the instrument, and convergent and discriminant validity was assessed by correlation between summary scor
The clean development mechanism (CDM), outlined in Article 12 of the Kyoto Protocol (UNFCCC 1997) is one of the most debated and disputed provisions of the current climate regime. Developing and developed states, business as well as environmental NGOs all seem to be dissatisfied with the mechanism in its current shape, and a reform of the CDM is therefore high on the agenda of the climate negotiat
The effect of various antipsychotics during pregnancy has repeatedly been studied, but for most atypical antipsychotics, only little information is available. We identified from the Swedish Medical Birth Register 2908 women who had reported the use of any antipsychotic or lithium in early pregnancy and studied malformation rates with data also from the Register of Congenital Malformations and the
Evaluation of prophylactic treatment of haemophilia requires sensitive methods. To design and test a new magnetic resonance imaging (MRI) scale for haemophilic arthropathy, two scales of a combined MRI scoring scheme were merged into a single scale which includes soft tissue and osteochondral subscores. Sixty-one joint MRI's of 46 patients with haemophilia were evaluated by four radiologists using
