We have discovered four extremely surprising emission lines of strontiumin ejecta near eta Carinae. Hubble Space Telescope (HST) SpaceTelescope Imaging Spectrograph (STIS) observations made in 1999 show twonarrow features whose wavelengths correspond to the forbiddentransitions of Sr II, and we have found no other plausibleidentification for these lines. The identifications are confirmed by newHST

This dissertation draws on postcolonial understandings in order to offer a sociological analysis of Lebanese immigrants in Montreal, New York City and Paris. I argue that the concept of diaspora provides a framework for understanding Lebanese immigrant experiences, as some immigrants may undergo a process of assimilation while others continue to hold on to their ethnic identities. Proposing that “

The Malay Peninsula is a crossroads for people, languages and cultural influences, apparent in today's vibrant mix of Malay, Chinese, Indian, Thai and European. Yet this modern state of affairs all but conceals signals of much older situations of diversity. Thus, some 140,000 people grouped together under the label Orang Asli (Malay for 'aboriginal people') represent a range of cultural and biolog

The thesis scrutinizes an emerging phenomenon in international relations: the increase in functional overlaps among international regimes. I approach this young field of study in three consecutive parts. The first part conceptualizes regime overlaps as ‘regime conflicts’. Following a broad sociological understanding of ‘conflict’, I define a regime conflict as an overlap among two or more internat

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Insulin är ett hormon som utsöndras från bukspottkörteln när koncentrationen av näringsämnen stiger i blodet. Insulinet transporteras via blodbanan till sina målvävnader; levern, skelettmusklerna och fettväven. Där binder det till insulinreceptorer på cellernas yta och insulinet medierar på så vis en rad olika effekter. Främst stimulerType 2 Diabetes is a disorder that increases globally, but mainly in the western world. One of the hallmarks of Type 2 diabetes is insulin resistance in the target tissues of insulin action (adipose tissue, liver and skeletal muscle). In addition, most patients with Type 2 diabetes are obese. Increased release of free fatty acids from the enlarged and/or dysfunctional adipose tissue is suggested t

The relationship between urinary levels of cotinine (U-cotinine) and arsenic (U-As), blood levels of cadmium (B-Cd), blood levels of lead (B-Pb), lung function, and questionnaire data on smoking habits were studied in 107 parents and their 46 children (7-10 y of age). There was a statistically significant relationship between the reported amount of tobacco smoked and U-cotinine levels. Nonsmokers

Human semen has several important constituents, including the prostate secreted proteins beta-microseminoprotein (MSP), prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP), and the seminal-vesicle-derived coagulum proteins semenogelin I (SEMG1) and semenogelin II (SEMG2). The research underlying this thesis explored the evolution, expression and structure of seminal plasma protein

Purpose: In one form of human autosomal recessive retinitis pigmentosa and in retinal degeneration (rd1) mouse, mutation occurs in the genes encoding ß subunit of rod photoreceptor cGMP phosphodiesterase. Therefore, rd1 mutant mouse is an appropriate model for human inherited retinal degeneration studies. Retinal explants are successfully cultured in serum free chemically defined R16 medium to eva

The inhibitory innervation of guinea-pig urethral smooth muscle was investigated histochemically and functionally. The distribution of immunoreactivities to haem oxygenases (HO), neuronal NO synthase (nNOS), and vasoactive intestinal polypeptide (VIP) was studied, and the functional effects of the corresponding putative transmitters, CO, NO, and VIP, were assessed. HO-2 immunoreactivity was found

Methacrylate-functionalized poly(ethylene oxide-co-ethylene carbonate) macromonomers were prepared in two steps by the anionic ring-opening polymerization of ethylene carbonate at 180 °C, with potassium methoxide as the initiator, followed by the reaction of the terminal hydroxyl groups of the polymers with methacryloyl chloride. The molecular weight of the polymer went through a maximum after app

With the introduction of mammographic screening the incidence of ductal carcinoma in situ (DCIS) has increased to 10-15% of all breast cancers. The aim of this study was to investigate whether there were any morphological and cell biological differences between DCIS detected during the pre-screening (n = 39) as opposed to the screening period (n = 120). We could not demonstrate any statistically s
