Impact of prolonged rainy seasons on food crop production in Cameroon

This study set out to examine why agricultural production in differing agro-ecological zones of the same country responds differently to a common environmental event (an extension of the rainy season). We find that the heavy reliance of farmers in the drier agro-ecological zones on seasonal cycles make them more vulnerable to an extension of the rainy season than those in regions where rainfall is

Pre-treatments for enhanced biochemical methane potential of bamboo waste

Various pre-treatments (acid, alkaline, enzyme and alkaline aided enzyme also termed combined) were evaluated on different fractions of bamboo waste from a chopstick production factory. Chemical oxygen demand (COD) solubilisation, monomeric/dimeric sugar yield, methane yield enhancement and methane production rate were assessed. The biochemical methane potential was determined in batch assays unde

MST With Conduct Disordered Youth in Sweden: Costs and Benefits After 2 Years

Objectives: The purpose of this study was to investigate the costs and benefits associated with multisystemic therapy (MST) for conduct disordered youth, 2 years following intake. Methods: The study employed a secondary analysis of 156 youth enrolled in a randomized trial assessing the psychosocial and behavioral outcomes of MST. Results: MST cost on average 105,400 SEK per youth. MST was associat

Large-scale pollination experiment demonstrates the importance of insect pollination in winter oilseed rape.

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

New μs Isomers in the Neutron-rich 210Hg Nucleus

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

Neighbourhood Environment and Stroke: A Follow-Up Study in Sweden

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 Y1 Receptor Hippocampal Overexpression Via Viral Vectors Is Associated With Modest Anxiolytic-Like and Proconvulsant Effects in Mice

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

Theory and Design of a CT Delta Sigma Modulator with Low Sensitivity to Loop-Delay Variations

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

Cost effectiveness of adding budesonide/formoterol to tiotropium in COPD in four Nordic countries

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

Photophysics of indole-2-carboxylic acid in an aqueous environment studied by fluorescence spectroscopy in combination with ab initio calculations.

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

Use and misuse of PLFA measurements in soils

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

Studying cyborgs: re-examining internet studies as human subjects research

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

Analysis of the Agrotis segetum pheromone gland transcriptome in the light of sex pheromone biosynthesis

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
