As with mosquitoes, female tabanid flies search for mammalian hosts by visual and olfactory cues, because they require a blood meal before being able to produce and lay eggs. Polarotactic tabanid flies find striped or spotted patterns with intensity and/or polarisation modulation visually less attractive than homogeneous white, brown or black targets. Thus, this reduced optical attractiveness to t

The technique of time-resolved pump-probe x-ray photoelectron spectroscopy using the free-electron laser in Hamburg (FLASH) is described in detail. Particular foci lie on the macrobunch resolving detection scheme, the role of vacuum space-charge effects and the synchronization of pump and probe lasers. In an exemplary case study, the complete Ta 4f core-level dynamics in the layered charge-density

BACKGROUND: In some animal studies, perfluorinated alkyl substances are suggested to induce weight gain. Human epidemiological studies investigating these associations are sparse. OBJECTIVE: We examined pregnancy serum concentrations of perfluorooctanoate (PFOA) and perfluoro-octane sulfonate (PFOS) and the prevalence of offspring overweight (> 1 SD) and waist-to-height ratio (WHtR) > 0.5 at 5-9 y

Objectives To determine the prevalence of HIV and related behavioural risks among Iranian female sex workers (FSW) via the first national biobehavioural surveillance survey. Methods In 2010, 1005 FSW were approached and 872 recruited using facility-based sampling from 21 sites in 14 cities in Iran. We collected dried blood samples and conducted face-to-face interviews using a standardised question

In endeavouring to explain the empirical puzzle that the sunk costs of exporting are important, but that, at the same time, trade flows do not, on average, survive for very long, this paper explores the concepts of core and peripheral markets. First, it illustrates that if the importance of sunk costs as well as the expected future returns from exporting are different, depending on whether the exp

Methylamine adsorption on the ordered Ni3Al(111) and NiAl(110) surfaces has been investigated by high resolution photoelectron spectroscopy and density functional theory calculations. Methylamine adsorbs molecularly at both surfaces at low temperature (90 K). The experiments show that methylamine interacts with the surface aluminium atoms on both surfaces, resulting in a positive binding energy sh

Popular Abstract in English Labour is said to be obstructed when the baby’s presenting part fails to descend through the birth canal despite strong uterine contractions. Obstructed labour is one of the major causes of maternal and neonatal mortality and morbidity in low-income countries. It is mostly caused by disproportion between the baby’s head and mother’s pelvis but also abnormal presentationLabour is said to be obstructed when the presenting part fails to descend through the birth canal despite strong uterine contractions. The condition is mostly prevalent in low-income countries where the main causes are cephalopelvic disproportion and malpresentation. The overall aim of this thesis was to investigate the individual, community and health system factors associated with obstructed lab

The design and pore distribution of the membrane are important factors in cross-flow membrane emulsification. To determine the effects of hydrodynamics and drop interaction on drop size, drop formation has been studied numerically using computational fluid dynamics (CFD). Oil with a viscosity of 7.0 mPa s was used as the dispersed phase and water was used as the continuous phase. The conditions st

Background- This nationwide study sought to determine age- and gender-specific familial risks in siblings hospitalized for venous thromboembolism (VTE). Methods and Results- The Swedish Multigeneration Register on 0- to 75-year-old subjects was linked to the Hospital Discharge Register for the years 1987-2007. Standardized incidence ratios were calculated for individuals whose siblings were hospit

Several protein kinase C (PKC) isoforms have been suggested as potential targets for breast cancer therapy. To explore the role for PKC isoforms in processes that facilitates malignant progression and the utility of PKC isoforms as biomarkers in breast cancer, we designed a study where we evaluated the expression of PKCα, δ, and ε in primary breast cancers as well as in breast cancer cell lines. W

We report a search for first generation scalar leptoquarks using 1.03 fb(-1) of proton-proton collisions data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS experiment. Leptoquarks are sought via their decay into an electron or neutrino and a quark, producing events with two oppositely charged electrons and at least two jets, or events with an electron, missing t

The last 20 years efforts to find a long-term and large-scale biofuel alternative to petrol and diesel for the transport sector have been intensified with a focus on liquid biofuels, such as ethanol, methanol and Fischer-Tropsh diesel derived from wood. The large-scale production of biomethane has so far largely been overlooked in comparative studies that focus on the long-term renewable options.

The thesis shows how different aspects of sustainable development have been handled or not handled in the third generation infrastructure development in Sweden. The difference between the design of the 3G development - emphasizing competition, growth and regional access, based on a strong technological optimism - and the implementation, as the roll out struck the landscape, including the non-handl

Background: The relation between vitamin D status and lymphoma risk is inconclusive. Objective: We examined the association between prediagnostic plasma 25-hydroxyvitamin D [25(OH)D] and lymphoid cancer risk. Design: We conducted a study nested within the European Prospective Investigation into Cancer and Nutrition cohort of 1127 lymphoma cases and 1127 matched controls with a mean follow-up time

Transport biofuels are currently the subject of heated debate in the EU. In the past decade the deployment of these technologies has been justified by claims of attractive environmental, geopolitical and rural development benefits. However, expectations have rapidly turned into deep criticism regarding the sustainability of these technologies and the desirability of pursuing the biofuel path. This

In 2000, the International Union of Geological Sciences (IUGS) ratified the decision from the International Working Group on the Cambrian–Ordovician Boundary (COBWG) to place the Global boundary Stratotype Section and Point (GSSP) for the base of the Ordovician System in the Green Point section, Newfoundland, Canada, at a point coinciding with the first appearance of the conodont Iapetognathus flu
