Popular Abstract in Swedish Kalcium är ett livsviktigt ämne för både djur och växter. Kalcium behövs t.ex. för uppbyggnaden av skelettet, för att hjärtat skall slå och för att musklerna skall dras samman. I växter är kalcium en viktig beståndsdel i cellväggarna och behövs också vid bl.a. celldelning. Trots detta måste koncentrationen av fria kalciumjoner inne i cellen (i cellvätskan) hållas mycket
For a Chinese high school graduate to be able to apply for university they must first take part in the yearly gaokao, the college entrance examination. The province where a student has his or her household registration determines where they can sit for the exam and also in which quota they are put when the university slots are allocated. This system causes difficulties for the children of migrantw
Dealing with water diffuse pollution is a major problem for watershed managers. This problem raises many complicated questions, which are important to answer in order to reach water environment protection goals. This study suggested some possible answers for the country of Lithuania. Among them were the identification of critical source areas, the identification of sensitive areas and the applicat
The mouse has seen limited use as a model for experimental otitis media, due primarily to the small size of its middle ear. However, the genetic resources of this species offer substantial potential benefits. These include detailed genomic information, a wealth of genetic models, and gene arrays that represent virtually all mouse genes. This has led to the development of methods for inducing otiti
Information on floral resource costs is fundamental for understanding how selection operates on floral morphology. In this study, I explored the cost of maturing flowers in a self-incompatible population of the ligulate composite Crepis tectorum L. by experimentally manipulating floral investment and then monitoring the response in reproductive effort. Plants on which the heads were removed during
Predator-prey interaction strengths in variable environments constitute a fundamental link to the understanding of aquatic ecosystem responses to environmental change. The present study investigates the effects of visibility conditions and prey fish density on predation rates of visually oriented piscivorous Eurasian perch Perca fluviatilis L. This was done in outdoor mesocosm (16 m(2)) experiment
The systematic review of universities and social innovations was carried out by placing universities within the broad framework of social innovation. Focus on social innovation as a response to development and societal problems, the review adopted a three-prong approach by analysing the drivers, process and impact of social innovations in the three core missions of universities: teaching, research
The International Association of Fire Safety Science (IAFSS) is comprised of members from some 40 countries. This paper presents the Association's thinking, developed by the Management Committee, concerning pressing research needs for the coming 10 years presented as the IAFSS Agenda 2030 for a Fire Safe World. The research needs are couched in terms of two broad Societal Grand Challenges: (1) cli
Foetal and neonatal alloimmune thrombocytopenia (FNAIT) is the platelet counterpart of haemolytic disease of the foetus and newborn. Among Caucasians, around 80 % of FNAIT cases and some of the most severe cases, are caused by alloantibodies against the human platelet antigen 1a (HPA-1a). For around 3 decades it has been known that almost all HPA-1a-immunised women are HLA-DRB3*01:01 positive. The
The problem of the orbital stabilization of the forced periodic motions of a non-linear all-wheel drive mechanical system is considered within the framework of a model that is widely used in problems of the planning of the motions and feedback design for industrial robotic manipulators. The basic result is the explicit indication of one of the possible redundant sets of coordinates tranverse to th
Bacterial endotoxin is a potent inflammatory antigen abundant in the human intestine. Endotoxins circulate in the blood at low concentrations in all healthy individuals. Elevated levels of circulatory endotoxins may cause inflammation with the development of chronic disease, either affecting metabolism, neurological disease, or resistance to viral and bacterial infections. The most important endot
Objective: To facilitate a greater likelihood of favorable response to new disease-modifying therapies, recruitment of patients at an earlier stage of their disease into clinical trials may be an attractive strategy. Hence, there is a need to develop widely accepted classification criteria for early-stage knee osteoarthritis (OA). We have proposed a set of classification criteria for early-stage k
Denna studie har undersökt hur ett företags medarbetares återhämtning ser ut och dess samband med förväntningar och förlängd jobbtillgänglighet. Friskvårdsbidrag och fritidsförlagd arbetstid har även undersökts i relation till återhämtning. Undersökningen gjordes genom en webbaserad enkät som skickades ut via företagets HR-personal. Utav populationen bestående av 25 medarbetare deltog 11. ResultatThis study has examined how co-workers in a company recover and how their recovery is connected to expectations and extended work availability. The use of the Swedish wellness grant and work during leisure is examined in relation to recovery. The study was executed through an internet survey and was sent out through the company's HR department. Out of a total population of 25, a total of 11 co
This essay uses the Factor Augmented Vector Autoregressive (FAVAR) approach to quantify the effects of monetary policy. Traditional methods to estimate the effects of monetary policy, such as Vector Autoregressive (VAR) models, have yielded unsatisfactory results, mainly due to sparse information sets included in the models. Augmenting the VAR model with factors summarizing the information of a va
This paper focuses on the use of relative clauses, specifically internally headed relative clauses in Japanese. Previous research on different types of relative clauses occurring in Japanese is also presented. The main purpose of the thesis is to give an up to date analysis of the understanding of relative clauses. A survey was carried out to further research at what point sentences with relative
Seventy-nine monoclonal antibodies submitted to the ISOBM TD-3 PSA Workshop were tested for their reactivity with recombinant human kallikrein-2 (rhK2). A sandwich immunofluorometric assay using polyclonal antiprostate- specific antigen (PSA) antiserum-coated plates was used to capture rhK2 and subsequently the test antibody. The response of each test antibody was compared with 3 reference antibod
Urban densification, despite the economic and social opportunities it offers, brings with it challenges to the well-being of citizens. A direct effect of densification is the rise in noise- and vibration-producing sources, which can lead to both health and comfort issues. In determining the risk associated with excessive vibration levels, the distance between the source and the receiver or target
Background: Pancreatic cancer has the lowest survival rate among all the major cancer types. Although recent decades have seen advances in diagnostic imaging, surgical techniques, perioperative care and oncological treatment, this has not been translated into major improvements in clinical outcome. The 5-year survival rate remains less than 10% for all stages. One important unmet clinical need is
The number of evacuees worldwide during wildfire keep rising, year after year. Fire evacuations at the wildland-urban interfaces (WUI) pose a serious challenge to fire and emergency services and are a global issue affecting thousands of communities around the world. But to date, there is a lack of comprehensive tools able to inform, train or aid the evacuation response and the decision making in c
