The present invention is based on the application of heating resistors by a temperature regulation circuit in certain points of the catalyzer so that this comes into operation in the least time possible, reducing most of the amount of low molecular stability or environmentally harmful substances. Likewise, little tumult are added to each monolith duct to raise exhaust gas turbulence and increase the contact between the reduction and oxidation agent, whether it be platinum, palladium and rhodium.

Solenodons are insectivores found only in Hispaniola and Cuba, with a Mesozoic divergence date versus extant mainland mammals. Solenodons are the oldest lineage of living eutherian mammal for which a mitogenome sequence has not been reported. We determined complete mitogenome sequences for six Hispaniolan solenodons (Solenodon paradoxus) using next-generation sequencing. The solenodon mitogenomes were 16,454-16,457bp long and carried the expected repertoire of genes. A mitogenomic phylogeny confirmed the basal position of solenodons relative to shrews and moles, with solenodon mitogenomes estimated to have diverged from those of other mammals ca. 78 Mya. Control region sequences of solenodons from the northern (n=3) and southern (n=5) Dominican Republic grouped separately in a network, with F

Objectives: Evaluate the impact of aspiration thrombectomy (AT) during primary coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) on clinical outcomes. Background: AT during PCI for STEMI may improve microvascular reperfusion, but its impact on clinical outcomes has remained controversial. Methods: We searched Pubmed, EMBASE, Medline, Scopus, CENTRAL, andClinicalTrials.gov databases on March 31, 2015 for randomized controlled trials that evaluated the use of AT with PCI compared with PCI alone for STEMI. The primary end point was all-cause mortality. Secondary end points included major adverse cardiac events (MACE, consisting of death, myocardial infarction, and target-vessel revascularization), recurrent myocardial infarction (MI), target-vessel revascularization (TVR), stent thrombosis and stroke. Results: Eighteen randomized controlled trials (n = 21,501) fulfilled the inclusion criteria. A total of 10,544 patients were treated with AT and PCI, compared to 10,957 control patients. The use of AT was not associated with a significant decrease in all-cause mortality (RR 0.88; 95% CI 0.78–1.01; P = 0.07), MACE (RR 0.93; 95% CI 0.86-1.00; P = 0.06), recurrent MI (RR 0.97: 95% CI 0.81–1.17; P = 0.77), TVR (RR 0.93; 95% CI 0.82–1.05; P = 0.23), stent thrombosis (RR 0.84; 95% CI 0.66–1.07; P = 0.17), or stroke (RR 1.35; 95% CI 0.86–2.11; P = 0.19). Conclusions: Using the totality of evidence available through 2015, this meta-analysis failed to show that the routine use of aspiration thrombectomy in patients with ST-elevation myocardial infarction significantly reduces all-cause mortality, MACE, recurrent MI, TVR, or stent thrombosis. The role of aspiration thrombectomy in selected patients with angiographic evidence of large thrombus burden requires further clinical investigation. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Nesting by marine turtles in the Caribbean has declined considerably, mainly because of human exploitation, but there has previously been no monitoring in the Dominican Republic. We present the first detailed assessment of the status of marine turtle nesting in the country, based on surveys during 2006-2010. Nesting populations of hawksbill Eretmochelys imbricata and leatherback turtle Dermochelys coriacea are of regional importance and the green turtle Chelonia mydas is still present, although nesting in low numbers. The two main nesting sites are within protected areas: the Jaragua National Park in the south-west, important for leatherback turtles (mean of 126 nests per season), and Del Este National Park on Saona Island in the south-east, principally for hawksbill turtles (mean of 100 nests per season). Comparison with historical data suggests all rookeries are profoundly reduced in size. Although the main nesting beaches are within protected areas, illegal egg-take and meat consumption continues there, and also elsewhere in the country. © 2012 Fauna & Flora International.

In this paper we design, by using the weight function technique, two families of iterative schemes with order of convergence eight. These weight functions depend on one, two and three variables and they are used in the second and third step of the iterative expression. Dynamics on polynomial and non-polynomial functions is analysed and they are applied on the problem of preliminary orbit determination by using a modified Gauss method. Finally, some standard test functions are to check the reliability of the proposed schemes and allow us to compare them with other known methods. © 2014 Taylor & Francis.

In this paper, by using a generalization of Ostrowski’ and Chun’s methods two bi-parametric families of predictor–corrector iterative schemes, with order of convergence four for solving system of nonlinear equations, are presented. The predictor of the first family is Newton’s method, and the predictor of the second one is Steffensen’s scheme. One of them is extended to the multidimensional case. Some numerical tests are performed to compare proposed methods with existing ones and to confirm the theoretical results. We check the obtained results by solving the molecular interaction problem. © 2014, Springer International Publishing Switzerland.

The present study examined the perceived importance, easiness to overcome and criticality of 29 barriers to productivity improvement in the Dominican Republic. It surveyed 134 construction professionals with 5 or more years of experience, who provided their assessment in the dimensions of importance and easiness to overcome on a Likert scale from 1 to 5. Barriers were grouped into environment driven, topmanagement driven and field-management driven. Two secondary questions explored attitudes towards education in productivity improvement. Respondents gave high average grades of 4.01 to 4.69 to all questions in the dimension of Importance. Average responses for Easiness to overcome were lower, had a broader range, from 2.31 to 3.74 and showed a more nuanced deliberation of possibilities. The criticality of some barriers seems difficult to justify using Lean Construction principles, and need further examination. Barriers with high criticality tended to be driven by field management, and those with low criticality tended to be driven by top management. Results point to an overall perceived need for improvement which is not followed by optimism for achieving it. The present study is the first of its kind in the Dominican Republic. Its results provide a roadmap for educational and managerial action in the immediate future. It can also serve as a foundation for similar studies in other developing countries.

In this paper, we present the results of the use of bifunctional polymeric films of polystyrene (10.3KD-49.5KD) to anchor oligo sequences of various lengths (15, 35 and 70-mer). The polymers were prepared by radical polymerization with 4,4'-azobis(4-cyanovaleric acid) as initiator and 3-Carboxy PROXYL to control the molecular weight and polydispersity. They were further modified with N-hydroxysuccinimide to anchor the (5'-AmMC 12) oligos. The anchoring reaction was done on a polymer-modified glassy carbon electrode. The probes were hybridized with their ferrocene-labeled complementary sequences. The hybridization reaction was followed by Osteryoung square wave voltammetry (OSWV). The calibration curve showed a narrow and sharp linear range between (5.7-8.0)×10 -7M and a detection limit around 0.55μM. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
