Three randomised controlled trials have shown a significant reduction in peri-operative mortality when comparing endovascular aneurysm repair (EVAR) with standard open surgery (1.7% v. 4.7% in the EVAR Trial 1; 1.2 v. 4.6% in the Dream Trial; 0.5 v. 3% in the OVER Trial1-3). EVAR has therefore become the standard of care in many centres. There are, however, patients who require EVAR because ope...

Alkali activated material has recently attracted great attention as an environmentally friendly building material. Generally, it exhibits higher mechanical properties and better durability when compared with Portland cement based materials. In this article, mixed alkali activated systems consisting of N-A-S-H and C-A-S-H hydrated gels were produced, using metakaolin as a dominated starting mate...

Studies on actinobacterial diversity in limestone habitats are scarce. This paper reports profiling of actinobacteria isolated from Hundung limestone samples in Manipur, India using ARDRA as the molecular tool for preliminary classification. A total of 137 actinobacteria were clustered into 31 phylotypic groups based on the ARDRA pattern generated and representative of each group was subjected ...

earlier Latin literature; they adopted instead the manner and the matter of Alexandrian poetry, particularly of Callimachus. They wrote urbane short poems and recondite epyllia; they made use of Greek words in transliteration and of learned allusions after the manner of the Alexandrians; they polished the hexameter to such a degree that Catullus, in poem 64, shows not a single violation of Herm...

The effects of a bio-treatment on limestone (here tuffeau) is measured over a large number of dryingimbibition cycles. A model based on a space-dependent permeability coefficient is proposed. It leads to a non-linear diffusion model which accounts for the deviation from the standard Washburn model. Keyword: Limestone, bio-mineralization, water transfer, imbibition, non-linear diffusion

Left retroperitoneal approach for open repair of abdominal aortic aneurysms is well established safety and efficacy. The proliferation endovascular repairs has changed the landscape pattern aneurysmal disease treated with repairs. purpose this study to evaluate outcomes performed via left based on outflow configurations. A single-institution surgery management system was queried aneurysm from 1...

Eucalyptus globulus Labill is the main exotic broadleaf species planted and managed for pulp and energy production in Spain, where it covers an area of more than 0.6 million ha. The climatic and soil conditions of the planting areas range from the predominantly acidic or fertile soils developed over limestone in Atlantic areas of the north and northwest of the Iberian Peninsula to the less weat...

In the title compound, [AuI(C(19)H(15)OP)(2)], the complete mol-ecule is generated by the application of twofold symmetry. The Au(I) atom is in a trigonal-planar geometry within an IP(2) donor set with the greatest distortion seen in the P-Au-P angle [128.49 (3) °]. Close intra-molecular Au⋯O inter-actions [3.172 (3) Å] are observed. No specific inter-molecular inter-actions are noted in the cr...

The aim of this study was to analyze yields, biological efficiency, earliness (expressed as days to first harvest), and precociousness and establish models for the mushroom growing according to these parameters. The experiment followed a double factorial design with four sources of calcium (calcitic limestone, calcitic limestone + gypsum, dolomitic limestone and dolomitic limestone + gypsum) an...

Ionizing radiations emanating from human natural environment could have serious negative effects at certain exposure level. Therefore the evaluation of radioisotopes origin becomes very important in order to achieve specific objective quantifying radiological parameters and their respective health implications. Hence estimation Activity Utlization Index (AUI) Excess Lifetime Cancer Risk (ELCR) ...
