It has been reported from one field observation in Belgium that great tits can use conifer needles to extract larvae from bark crevices in trees. In a laboratory experiment I tested if great tits could use tools to extract mealworms in a similar way as in the field observation. I tested two different types of tools, sticks and hooks, in trials where the birds could extract a mealworm from a transp
At present China suffers from severe desertification or land degradation. About 27% of the total territory was exposed in 2004, mainly the northern provinces. Consequences of desertification, such as floods or sandstorms, require huge effort and financial assets. Soil moisture understanding plays a key role in combating desertification and is necessary in order to implement a sustainable water man
Populärvetenskaplig sammanfattning: Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. Detta började med att bönderna i slutet av 1600-talet erhöll en stor del av adelns jord. De fick således förvalta sin egen vinst, vilket resulterade i en rad nyodlingar och tekniska hjälpmedel. I början av 1900-talet introducerades konstgödslet och efter andra världskriget Human-induced eutrophication has rapidly become one of the most important environmental issues. The problem is largely due to the shift in agricultural practices. Farming methods have become more efficient during the last 300 years. Watercourses have been straightened out and wetlands have been reduced to increase agricultural landuse. Since the end of the 1940s, fertilization has increased dramat
Popular Abstract in Swedish På apoteket hittar vi den ena burken efter den andra med olika sorters smärtstillande medicin. Hur många av dessa är verkligen effektiva mot ihållande och svår smärta? Många receptbelagda läkemedel som lindrar smärta förändrar samtidigt vårt beteende, till exempel vår förmåga att fatta beslut. De kan dessutom också orsaka slöhet och onormal koordination. För att kunna
Objective: Glucose degradation products (GDPs) in peritoneal dialysis (PD) fluids are cytotoxic and affect the survival of the peritoneal membrane. One of the most reactive GDPs in PD fluids is 3,4-dideoxyglucosone-3-ene (3,4-DGE). 3,4-DGE has been reported as an intermediate between 3-deoxyglucosone (3-DG) and 5-hydroxymethyl furaldehyde (5-HMF) during degradation of glucose. In PD fluids, 3,4-DG
BACKGROUND: Frequent hyperglycemic episodes are increasingly being associated with an increased risk of type 2 diabetes and cardiovascular disease. OBJECTIVE: We studied the extent to which acute glycemia and glycemia after subsequent meals can be modulated by the characteristics of cereal foods, such as glycemic index (GI) and content of indigestible carbohydrates. DESIGN: Twelve healthy subjects
Som minst är alltid 5% av jordens yta täckt av havsis. Det gör att isen har en avgörande roll i klimatet, särskilt vid polerna, då den påverkar utbytet av värme, massa och rörelse mellan havet och atmosfären. Ett snötäcke ovanpå isen förstärker ytterligare effekterna av isolering och reflektion. Havsisen och snön är av stor betydelse för det globala klimatsystemet. Dock är det svårt att inhämta dThe sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. Sea ice and snow is of significant

Öresund is a very dynamic economic area with numerous projects, there is a great need of a deeper understanding of the wave climate. The wave measurements currently available are scarce and they do not cover the whole area. For this reason, a modeled wave climate would be of interest and the results could be a starting point for different in depth analysis. The objective of this study was to prod
Research show that human trafficking is one of the fastest growing criminal industries today, after narcotics and illegal arms trade (The Polaris Project 2014). The most common victims of human trafficking are stated to be women and children (UNODC 2012). According to the UNICEF (2007), 1,2 million children are estimated to be exposed to trafficking for various exploitative purposes every year aro
Introduction: In former studies from North America early Do-Not-Resuscitate orders (DNR orders) in patients with intracerebral haemorrhage (ICH) had negative prognostic impact on mortality. The influence of DNR orders on functional outcome and whether DNR orders are grounded on relevant patient characteristics is unknown. We aimed to determine the frequency and predictive factors of DNR-orders and
The importance of carbohydrates in biological systems has become evident during the last fifty years. It is well known that pathogenic bacteria and viruses attach to glycoconjugates present at mammalian cell surfaces, and that this attachment is a prerequisite for the later stages of infection. Obviously, this interaction is interesting as a target for the development of novel ways to treat bacter
The global mobility is constantly increasing and numerous of international groups have recognised the need for a dynamic workforce. In order to adapt to the international market and to widen the knowledge within a multinational group, employees are seconded between affiliated companies. The secondment of an employee puts several questions of taxation to the fore. Primarily, the issue as to where t
OBJECTIVE: The study was performed in order to evaluate to what extent hypertension or diabetes mellitus may affect the urinary excretion rate of Tamm-Horsfall protein. MATERIALS AND METHOD: The urinary excretion rates of albumin and Tamm-Horsfall protein, a measure of glomerular and distal tubular function, respectively were measured in patients with essential hypertension (n = 17) and in type 1
In 1990, a joint Nordic-Russian project was initiated in order to make independent estimations of the effective dose to selected groups of inhabitants in a highly contaminated area around the city of Novozybkov In the western Bryansk region of Russia. The inhabitants were living in six villages with initial contamination levels of Cs-137 between 0.9 and 2.7 MBq m(-2). Some villages had been decont
Pancreatic cancer is an aggressive malignancy that carries a high mortality rate. A major contributor to the poor outcome is the lack of effective molecular markers. The purpose of this study was to develop protein markers for improved prognostication and noninvasive diagnosis. A mass spectrometry (MS)-based discovery approach was applied to pancreatic cancer tissues and healthy pancreas. In the v
Aim: To examine the hypothesis that, based on their glucose curves during a seven-point oral glucose tolerance test, people at elevated type 2 diabetes risk can be divided into subgroups with different clinical profiles at baseline and different degrees of subsequent glycaemic deterioration. Methods: We included 2126 participants at elevated type 2 diabetes risk from the Diabetes Research on Patie
Introduction: Osteoarthritis (OA) is one of the most common causes of knee pain, and the most common form ofarthritis. It causes pain and disability, and there is currently no cure. Recent research in knee OA highlights therole of the meniscus in OA pathology. In this thesis, the overall aim was to study the proteome and microstructureof the human meniscus, both in healthy subjects and OA patients
Introduction/Background Completetumor resection is the most relevant prognostic factor for overall survival in high grade serous ovarian cancer (HGSOC) patients. The current standard for classification of postoperative residual disease is surgeon´s subjective evaluation at the end of surgery. Thus, a reliable objective predictive marker is currently missing.MethodologyIn this prospective single-ce
Oats (Avena sativa) are a versatile cereal crop cultivated worldwide. Accounting for 2% of global grain production, they rank as the seventh most important cereal. Approximately 23 million tonnes of oat grain is produced annually, with the majority stemming from spring-sown cultivars in Canada, Russia, and Northern Europe. Although used mostly for animal feed, oats have increased in their populariOats (Avena sativa) is a versatile crop grown worldwide for animal feed and human consumption. Humanoat consumption has recently risen due to its various health benefits. However, oats are susceptible toFusarium head blight (FHB) caused by various Fusarium fungi. FHB reduces yield and leads to mycotoxinaccumulation. The most commonly reported mycotoxins in oat are trichothecenes deoxynivalenol (DO
