Insect pollination, despite its potential to contribute substantially to crop production, is not an integrated part of agronomic planning. A major reason for this are knowledge gaps in the contribution of pollinators to yield, which partly result from difficulties in determining area-based estimates of yield effects from insect pollination under field conditions. We have experimentally manipulated

Neutron-rich nuclei in the lead region, beyond N = 126, have been studied at the FRS-RISING setup at GSI, exploiting the fragmentation of a primary uranium beam. Two isomeric states have been identified in Hg-210: the 8(+) isomer expected from the seniority scheme in the vg(9/2) shell and a second one at low spin and low excitation energy. The decay strength of the 8(+) isomer confirms the need of

Background: In recent years, research on the association between physical environments and cardiovascular disease outcomes has gained momentum with growing attention being paid to Geographic Information Systems (GIS). This nationwide study is the first to examine the effect of neighbourhood physical environments on individual-level stroke, using GIS-based measures of neighbourhood availability of

Neuropeptide Y (NPY) exerts anxiolytic-and antidepressant-like effects in rodents that appear to be mediated via Y1 receptors. Gene therapy using recombinant viral vectors to induce overexpression of NPY in the hippocampus or amygdala has previously been shown to confer anxiolytic-like effect in rodents. The present study explored an alternative and more specific approach: overexpression of Y1 rec

This paper presents a 3rd-order, 3-bit continuous-time (CT) \Updelta\Upsigma Δ Σ modulator for an LTE radio receiver. A return-to-zero (RZ) pulse, centered in the sampling period by a quadrature clock, is used in the innermost DAC to reduce the sensitivity to loop-delay variations in the modulator, and omit implementing the additional loop delay compensation usually needed in CT modulators. The pe

Objective: Assess the cost effectiveness of budesonide/formoterol (BUD/FORM) Turbuhaler (R) +tiotropium (TIO) HandiHaler (R) vs. placebo (PBO)+TIO in patients with chronic obstructive pulmonary disease (COPD) eligible for inhaled corticosteroids/long-acting beta(2)-agonists (ICS/LABA). Methods: The cost-effectiveness analysis was based on the 12-week, randomised, double-blind CLIMB trial. The stud

Artikeln presenterar kortfattat min forskning om etiska frågor kring nutritionell genomik och dess tillämpning i personaliserad nutrition.

The photo-physics and -chemistry of indoles are known to be highly complex and strongly dependent on their precise molecular structure and environment. Combination of spectroscopic analysis with quantum chemical calculations should be a powerful tool to unravel precise excited state deactivation mechanisms. At the same time, combined studies are seldom and likely far from trivial. In this work we

The determination of the phospholipid fatty acid (PLFA) pattern of soil organisms has become one of the most commonly used methods to study microbial community structure. Here we recapitulate the background of our work applying the PLFA method to soil in the early 1990s. We also stress that although the PLFA method was, and still is, a rapid and sensitive method to detect changes in the microbial

Virtual communities and social networks assume and consume more aspects of people's lives. In these evolving social spaces, the boundaries between actual and virtual reality, between living individuals and their virtual bodies, and between private and public domains are becoming ever more blurred. As a result, users and their presentations of self, as expressed through virtual bodies, are increasi

Background: Moths rely heavily on pheromone communication for mate finding. The pheromone components of most moths are modified from the products of normal fatty acid metabolism by a set of tissue-specific enzymes. The turnip moth, Agrotis segetum uses a series of homologous fatty-alcohol acetate esters ((Z)-5-decenyl, (Z)-7-dodecenyl, and (Z)-9 tetradecenyl acetate) as its sex pheromone component

In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. In low-multiplicity collisions, unlike in high-multiplic

A key aspect of leadership is the followers’ constructions of its value and relevance. Based on two empirical, qualitative case studies, this paper highlights the importance of the ‘demand’ for leadership when leader–follower relationships are established. We further discuss how followers influence, inhibit and initiate managerial leadership (i.e. leadership acts from their formal superior targeti

Background: This contribution deals with chemical processes at the biological membranes of endothelial cells in blood vessels. A basic observation is that the intensity of blood flow navigates the vascular width through a negative feedback circle. When the blood flow increases, the vessels become wider; when it decreases the vascular smooth muscle cells contract. The anionic polyelectrolyte hepara
