The chemosensory gene families of insects encode proteins that are crucial for hostlocation, mate finding, oviposition, and avoidance behaviors. The insect peripheralchemosensory system comprises odorant receptors (ORs), gustatory receptors (GRs),ionotropic receptors (IRs), odorant binding proteins (OBPs), chemosensory proteins(CSPs), and sensory neuron membrane proteins (SNMPs). These protein fam

We analyzed seasonal influenza vaccination coverage among the Italian healthcare workers (HCW) in order to identify socio-demographic and clinical determinants of vaccination. We used data from the survey "Health and health care use in Italy," which comprised interviews of 5,336 HCWs For each respondent, information on socioeconomic, health conditions, self-perceived health and smoking status were

Background: Accurate assessment of polyphenol intakes is needed in epidemiologic research in order to study their health effects, and this can be particularly challenging in international study settings. Objective: The purpose of this work is to describe the procedures to prepare a comprehensive polyphenol food-composition database that was used to calculate standardized polyphenol intakes from 24

The aim of this study was to investigate which preventive measures targeting mastitis are implemented in Swedish dairy herds with different housing and milking systems. Data were collected through a self-administered postal questionnaire sent to 898 dairy farmers, stratified by housing and milking system, in May 2011. The questionnaire contained general questions about the herd and the person resp

The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. Industrial processes that can cause exposure to isocyanates are, for example, spraying or heat

Jordan has one of the lowest available water supplies in the world; meanwhile Jordan has seen large increase in population and refugee’s fluxes, leading to an increase in water demand [1]. To address this unprecedented water scarcity, Jordan’s water must be used where its social and economic value is highest. Jordan must treat and reuse virtually every drop of water. It is expected to have more th

Popular Abstract in Swedish Snabba fenomen, som inträffar efter laserexcitation, har studerats med tidsupplöst röntgendiffraktion (TXRD). I de flesta experimenten har en ljuspuls från en femtosekundlaser använts för att excitera provet, och dynamiken har undersökts med röntgenljus. Tidsupplösta röntgendiffraktionsmätningar har utförts för att studera fasta halvledarmaterial, vätskor, ferro-elektriFast phenomena occurring after laser excitation were studied using time-resolved X-ray diffraction (TXRD). In most experiments, a femtosecond laser pulse was used to excite the sample, and X-rays were used as a probe. The X-ray diffraction technique was used to study bulk semiconductor samples, molten liquids, ferro-electric domain switching in potassium dihydrogen phosphate (KDP), and strain prop

Inom kärnkraftsindustrin är säkerhet den aspekt som prioriteras högst. Alla kärnkraftverk är designade för att i högsta möjliga mån förhindra läckage av radioaktivetet till omgivningen, både under drift och i händelse av en allvarlig olycka. Med anledning av detta är reaktorinneslutningens vägg en av de viktigaste säkerhetsrelaterade konstruktionerna vid en anläggning, detta då denna konstruktionsSafety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. The containment wall is the last main barrier to prevent radioacti

Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,

This thesis deals with two types of problems occurring in inventory theory; pooling of stock and perishable items. All three papers in this thesis consider inventory distribution systems with continuous review. In Paper I we consider a single-echelon inventory system with two identical locations. Demands are generated by stationary and independent Poisson processes. In this paper, we allow later

There is a growing interest within the Wastewater Treatment Plant (WWTP) modelling community to correctly describe physico-chemical processes after many years of mainly focusing on biokinetics. Indeed, future modelling needs, such as a plant-wide phosphorus (P) description, require a major, but unavoidable, additional degree of complexity when representing cationic/anionic behaviour in Activated S

This paper combines epidemiological data on musculoskeletal morbidity in 40 female and 15 male occupational groups (questionnaire data 3720 females, 1241 males, physical examination data 1762 females, 915 males) in order to calculate risk for neck and upper limb disorders in repetitive/constrained vs. varied/mobile work and further to compare prevalence among office, industrial and non-office/non-

The European electric power industry has undergone considerable changes over the past two decades as a result of more stringent laws concerning environmental protection along with the deregulation and liberalization of the electric power market. However, the pressure to deliver solutions in regard to the issue of climate change has increased dramatically in the last few years and has given rise to

Biogenic volatile organic compounds (BVOCs) emitted by vegetation play an important role for aerosol mass loadings since the oxidation products of these compounds can take part in the formation and growth of secondary organic aerosols (SOA). The concentrations and properties of BVOCs and their oxidation products in the atmosphere are poorly characterized, which leads to high uncertainties in model

It has been generally accepted that residual cartilage and subchondral bone has to be removed in order to get bony fusion in arthrodeses. In 1998 we reported successful fusion of 11 rheumatoid ankles, all treated with percutaneous fixation only. In at least one of these ankle joints there was cartilage left. More than 25 rheumatoid patients with functional alignment in the ankle joint have subsequ

Popular Abstract in Swedish Ytaktiva ämnen (tensider) har många olika användningsområden, bl.a. är de en viktig beståndsdel i tvättmedel, hygienprodukter och en del läkemedel och livsmedel. Tensider används av en mängd olika orsaker, t.ex. kan de stabilisera lösningar och lösa upp fett. Det speciella med dessa ytaktiva ämnen är att de består av en hydrofil del som gillar vatten och en hydrofob delThis thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. In the wetting experiments, water, alcohols, aqueous surfactant solutions and commercial ink-jet inks were used as test liquids, and a number of substrates, including silicate

The bio-economy has been put forward as a strategy to increase economic growth without this leading to increased emissions of greenhouse gases. A key concept behind the bio-economy is the increased use of biomass for applications such as the production of bio-based chemicals and materials but also an increased importance for biotechnology and biorefinery systems in the production of these products

Mechanistic understanding of piscivore foraging at the individual level is important in order to understand and make predictions of piscivore effects at population and community levels. To understand the mechanisms affecting selection and consumption rates each step in the foraging cycle (search, encounter, active choice, attack, capture, ingestion, digestion) should be studied. In my studies of d
