Particle Induced X-ray Emission is a well-established technique for quantitative elemental analysis down to trace levels. During microbeam analysis, where the beam is collimated and focused into a small spot, the beam current reduces to nA or less. The generation of characteristic X-rays is reduced in the same proportion, leading to long data-acquisition times. This can partly be compensated for b
Non-native animals can encounter very different environments than those they are adapted to. Functional changes in morphology, physiology and life-history following introduction show that organisms can adapt both fast and efficiently. It remains unclear, however, if female reproductive characters and male sexually selected behaviour show the same adaptive potential. Furthermore, the invasion succe
We present a study of high-order-harmonic generation (HHG) assisted by extreme ultraviolet (XUV) attosecond pulses, which can lead to the excitation of inner-shell electrons and the generation of a second HHG plateau. With the treatment of a one-dimensional model of krypton, based on time-dependent configuration interaction singles (TDCIS) of an effective two-electron system, we show that the XUV-
We investigate ionization of neon atoms by an isolated attosecond pump pulse in the presence of two coherentextreme ultraviolet or x-ray probe fields. The probe fields are tuned to a core-valence transition in the residual ionand induce spectral shearing of the photoelectron distributions. We show that the photoelectron-ion coincidencesignal contains an interference pattern that depends on the tem
Background: Use of disposable protective gloves in health care is necessary both to protect patients and personnel. However, the use might also be responsible for skin disease among persons wearing the gloves. Dermatitis may be caused by additives in the gloves, either from manufacturing of the glove material or components in coatings applied after vulcanization. Objectives: We wanted to analyse t
Recent data on the prevalence and causes of hand eczema among healthcare workers in Sweden are lacking. Multidrug-resistant bacteria have necessitated improved hand hygiene and preventive measures. This has led to an increase in the use of disposable rubber gloves and hand disinfectants, which might influence the risk of hand eczema. Our aims were to identify healthcare workers with hand eczema; t
Background: For health care personnelhandhygieneandwearing appropriate protective gloves are compulsory. We have noticed an increase of hand eczema caused by contact allergy from rubber chemicals such as diphenylguanidine (DPG) in synthetic rubber gloves used by surgeons and surgical nurses. The exposure time to surgical gloves as well as the number of gloves used per day vary. Furthermore surgery
Background: Recently it was suggested to use aluminium chloride hexahydrate in petrolatum at 10% to detect aluminium contact allergy. Patch testing with aluminium chloride hexahydrate at 20% did not demonstrate a higher number of positive test reactions. It was speculated that the constricting effect of aluminium salts might impair skin penetration. Objectives: The purpose of the present study is
Background: In the Department of Occupational and Environmental Dermatology there has been an increase in the inflow of patients, working as surgical nurses or surgeons. They have been referred due to presumed occupational contact dermatitis. Results from investigated patients have in part been presented previously, where the investigation has shownmultiple contact allergies caused by their occupa
We have previously shown that the presence of pancreatic enzymes in the gut lumen of exocrine pancreatic insufficient pigs influences blood glucose and insulin levels during an intravenous glucose tolerance test (IVGTT). The present study aims to highlight the effects of orally applied pancreatic-like enzymes on blood glucose and plasma insulin levels during an IVGTT in young intact pigs. Five, 7-
Saklighet och neutralitet skall idealtypiskt karakterisera byråkratins ”emotionella regim” eller affektiva ton. Max Weber karakteriserade den idealtypiska byråkratin: sine ira ac studio (utan ilska eller förkärlek). Trots detta var möten och dokument i ett ungdomsvårdsprojekt omgärdade med en intensiv involvering och beskrevs ofta i känslomässiga termer. Känslor som ilska, förbittring, och ibland
Human Protein Reference Database (HPRD) is an object database that integrates a wealth of information relevant to the function of human proteins in health and disease. Data pertaining to thousands of protein-protein interactions, posttranslational modifications, enzyme/substrate relationships, disease associations, tissue expression, and subcellular localization were extracted from the literature
It has been argued that the fundamental cause of Africa’s current relative poverty is a lack of pro-growth institutions deriving either from the colonial system, the period of slavery, or from particular geographic or population characteristics. This article takes a fresh look at estimates of African country incomes. It subjects the available datasets to tests of accuracy, reliability, and volatil
Given shortcomings in basic data collection and insufficient resources in preparing official statistics African growth data are unlikely to be very reliable. Estimates of an annual growth rate of 3 per cent may be consistent with a reality between 0 and 6 per cent growth. Although data from international databases are widely used in an expanding literature on African growth there has been no resea
