Ten compounds of dimolybdenum are studied using density functional theory and time-dependent density functional theory. The energy of the strongest symmetry-allowed bands is calculated. The results are then compared with experimental data, when available. The PW91 functional gives results for geometry and for the energy of the δ→δ∗ band that show good agreement with experimental data. However, the B3LYP functional gives more realistic values for the whole spectrum when the results are compared with experimental data. Finally, the different values of energy of these bands are explained analyzing the molecular orbitals involved in these transitions. Some ligands can act as an unsaturated system in conjugation with the delta bond, modifying the energies of the electronic transitions. © 2016 Published by NRC Research Press. Source

Aims/hypothesis To assess the feasibility and effectiveness of an active real-life primary care lifestyle intervention in preventing type 2 diabetes within a high-risk Mediterranean population. Methods A prospective cohort study was performed in the setting of Spanish primary care. White-European individuals without diabetes aged 45-75 years (n02,054) were screened using the Finnish Diabetes Risk Score (FINDRISC) and a subsequent 2 h OGTT. Where feasible, high-risk individuals who were identified were allocated sequentially to standard care, a group-based or an individual level intervention (intensive reinforced DE-PLAN [Diabetes in Europe-Prevention using Lifestyle, Physical Activity and Nutritional] intervention). The primary outcome was the development of diabetes according to WHO criteria. Analyses after 4-year follow-up were performed based on the intention-to-treat principle with comparison of standard care and the combined intervention groups. Results The standard care (n0219) and intensive intervention (n0333) groups were comparable in age (62.0/62.2 years), sex (64.4/68.2% women), BMI (31.3/31.2 kg/m2), FINDRISC score (16.2/15.8 points), fasting (5.3/5.2 mmol/l), 2 h plasma glucose (7.1/6.9 mmol/l) and self-reported interest to make lifestyle changes at baseline. Diabetes was diagnosed in 124 individuals: 63 (28.8%) in the standard care group and 61 (18.3%) in the intensive intervention group. During a 4.2-year median follow-up, the incidences of diabetes were 7.2 and 4.6 cases per 100 person-years, respectively (36.5% relative risk reduction, p<0.005). The number of participants needed to be treated by intensive intervention for 4 years to reduce one case of diabetes was 9.5. Conclusions/interpretation Intensive lifestyle intervention is feasible in a primary care setting and substantially reduces diabetes incidence among high-risk individuals.

The marine benthic cartography of the Cap de Creus and surrounding areas (NW Mediterranean Sea) was obtained by combining classical grabbing methods with more recent imaging methods based on a remotely operated vehicle. The goals of this particular survey can be summarized as follows: 1) to chart the benthic communities (and the area of each one); 2) to evaluate the benthic diversity of the areas; 3) to produce visual documentation of the distributions of the benthic organisms; 4) to identify human-induced pressures on the benthic environment; 5) to make recommendations for future management based on the visual assessment; and 6) to set up a new methodology for making large biocenosis maps that would help to manage marine protected and non-protected areas. The marine environment off the Alt Empordà County was shown to have a very rich diversity of benthic habitats. Twenty community categories were identified from videos and grabs. Though benthic habitats mostly located inside a marine protected area were assessed, man-made objects were seen in 10% of the analyzed minutes filmed. The study led to a comprehensive review of the main biotope systems of this coastal area, as well as their environmental condition, and this will be an essential element for their future management.

Severe hypoglycaemia has recently been associated with an increased risk for cardiovascular disease (CVD) in diabetes. The retrospective analysis of a national registry on continuous subcutaneous insulin infusion points to a higher prevalence of CVD in Type 1 diabetic subjects with repeated severe hypoglycaemia at the time of starting CSII. © 2012 Elsevier Ireland Ltd.

Dose expression and volume rate are key questions for spray application in orchard and vineyard plantations. Crop characteristics seem to be one of the most important factors to determine the optimal value, but parameters as the leaf area, canopy volume, and canopy density are difficult to quantify. dosaviña, a decision support system, has been developed as a tool to calculate the optimal volume rate for spray applications in vineyards. The method is based on achieving the optimal coverage (impactscm-2) according to the characteristics of the crop canopy, and includes the establishment of an efficiency factor that depends on aspects such as the type of sprayer used, nozzle type and size, operational parameters, and weather conditions. Field tests, in order to evaluate the interest in and functionality of the dosaviña computer program, were arranged for different wine grape varieties in New York State (USA) and Lleida (Spain), with a wide spectrum of wine varieties (Baco, Riesling, Vignoles, Merlot, and Cabernet Sauvignon), sprayers, and working conditions. Deposition, uniformity, and control of different diseases (powdery mildew, Botrytis bunch rot, and grape black rot) were evaluated at different crop stages, by comparing the volume rate applied according to dosaviña with the conventional rate most generally used by farmers. The volume rate was reduced by an average 39.9% for dosaviña, with similar or even higher values of deposition and uniformity. The resulting reduction in pesticide use (average 53%) did not present any difference in disease control for the selected varieties. Methodologies based on coverage and leaf area, as prescribed by dosaviña, seem to be an effective alternative approach to determine the most adequate volume rate according to the canopy structure, with the consequent diminution of pesticide use and the increase of environmentally friendly practices. © 2011 Elsevier B.V.
