Abstract: We determined the frequency of intestinal parasites and risk factors in school children of the parish Cuji, Barquisimeto, Lara State, from march to september 2011, students were distributed according to the presence and type of parasitism, sex, age, socioeconomic status, use of water and salads also investigated the water contamination and the lettuce purchased by the community. We performed a cross-sectional study with 232 students, selected by simple probability sampling. Informed consent, the representatives held a survey related to the objectives and requested a stool sample for analysis by direct examination with saline, iodine, and Kato, Quensel. Were parasitized 36.6% of those tested, being more frequent in children of 12 years (16.5%) and predominantly in females (57.6%) The most frequent species was Blastocystis hominis with 68.2%. Parasites, 71.8% were monoparasitism, 72.9% belonged to Stratum IV as Graffar, and 69.4% consumed raw salads. Only 20% were contaminated lettuce. There was no difference with respect to non-parasitized according to socioeconomic status, water consumption and raw salads, perhaps due to the homogeneity of these risk factors in this community. But highlights the high prevalence of protozoa and the high frequency of monoparasitism. The findings of this research will open the way for future studies and the creation of educational and preventive programs.

Theoretical Considerations about the Steady State Combustion of Wood Char in a Bubbling Fluidized Bed Reactor  [PDF]
Carlos Pinho
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.53021
Abstract:

A theoretical study on the performance of steady state bubbling fluidized bed burners is presented using a simple mathematical model. The proposed model has pedagogical and practical advantages due to its simplicity. The calculations, whose results are plotted in several graphics, were based on data obtained in laboratory scale experiments. The experiments were carried out with wood chars and the model allows a proper evaluation of physical and chemical phenomena taking place inside the reactor, as well as a fast approach to the pre-design phase, before going towards more complex and time consuming numerical modeling. In the first part of the paper the steady state modeling is compared with the combustion of successive batches of char particles. Afterwards, the performance of a 1 m diameter bed operating from 700 to 800 is shown.

Abstract: Vascular endothelial growth factor (VEGF) is up-regulated during mesothelial to mesenchymal transition (MMT) and has been associated with peritoneal membrane dysfunction in peritoneal dialysis (PD) patients. It has been shown that normal and malignant mesothelial cells (MCs) express VEGF receptors (VEGFRs) and co-receptors and that VEGF is an autocrine growth factor for mesothelioma. Hence, we evaluated the expression patterns and the functional relevance of the VEGF/VEGFRs/co-receptors axis during the mesenchymal conversion of MCs induced by peritoneal dialysis. Omentum-derived MCs treated with TGF-β1 plus IL-1β (in vitro MMT) and PD effluent-derived MCs with non-epithelioid phenotype (ex vivo MMT) showed down-regulated expression of the two main receptors Flt-1/VEGFR-1 and KDR/VEGFR-2, whereas the co-receptor neuropilin-1 (Nrp-1) was up-regulated. The expression of the Nrp-1 ligand semaphorin-3A (Sema-3A), a functional VEGF competitor, was repressed throughout the MMT process. These expression pattern changes were accompanied by a reduction of the proliferation capacity and by a parallel induction of the invasive capacity of MCs that had undergone an in vitro or ex vivo MMT. Treatment with neutralizing anti-VEGF or anti-Nrp-1 antibodies showed that these molecules played a relevant role in cellular proliferation only in na?ve omentum-derived MCs. Conversely, treatment with these blocking antibodies, as well as with recombinant Sema-3A, indicated that the switched VEGF/VEGFRs/co-receptors axis drove the enhanced invasion capacity of MCs undergoing MMT. In conclusion, the expression patterns of VEGFRs and co-receptors change in MCs during MMT, which in turn would determine their behaviour in terms of proliferation and invasion in response to VEGF.
Implementing Good Governance Principles for the Public Sector in Information Technology Governance Frameworks  [PDF]
Carlos Juiz, Carlos Guerrero, Isaac Lera
Open Journal of Accounting (OJAcct) , 2014, DOI: 10.4236/ojacct.2014.31003
Abstract: In this paper, we are showing how Information Technology (IT) governance frameworks contribute to the implementation of the key principles of the good corporate governance, particularly, in the public sector. We demonstrate that there are numerous links, explicitly and implicitly expressed through a set of IT governance instruments, matching the proposals of good governance principles with the behavioral goals of an IT governance framework implementation. We also provide a real experience of using a set of possible instruments, in our public university, through an IT governance framework based on the ISO/IEC 38500 standard. We also present the maturity of the good governance principles implementation with this set of instruments, after governing IT in our university during the period 2007-2013. We show that using an IT governance framework in a public entity mutually reinforces the key principles of good governance, especially the transparency and accountability goals for the IT assets.
Comments on the Article “Improved Hemodynamics with the Use of Prophylactic Infusion of Epinephrine and or Norepinephrine during Transcatheter Aortic Valve Replacement (TAVR)”  [PDF]
Carlos Galhardo Jr., Carlos Darcy Alves Bersot
Open Journal of Anesthesiology (OJAnes) , 2015, DOI: 10.4236/ojanes.2015.510039
Abstract: Transcatheter aortic valve replacement (TAVR) is a new therapeutic option to treat patients with symptomatic severe aortic stenosis, and a prohibitive mortality risk for conventional surgical AVR2. A thorough understanding of the procedural steps involved in TAVR is imperative for all components of the heart time. Balloon aortic valvuloplasty under rapid ventricular pacing is one of the main procedural steps, and is usually performed before valve insertion to enable passage of the prosthesis through the stenotic native aortic valve. Hemodynamic collapse necessitating prompt intervention may occur at different stages during the procedure.
Freedom of Conscience is Freedom of Choice: Women’s Reproductive Needs, Rights, and their Therapeutic Implications  [PDF]
Carlos M. Del Rio
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.23028
Abstract: Using reasonableness, we examine the U.S. Catholic bishops’ opposition to provisions of the Affordable Care Act of 2010. Weaving contributions from theology, philosophy, and jurisprudence, we emphasize the reasonable importance of mental health therapy for women within a relevant Catholic/Christian dialogue, particularly in the wake of the U.S. Supreme Court’s decision on healthcare. We principally identify socially imbedded factors that contribute to ending unwanted pregnancies, and argue that freedom of conscience is indeed freedom of choice within which women’s reproductive needs lie under protections of the U.S. Constitution. We recognize that Catholic tradition originates in the words and behaviors of Jesus. Examining closely these actions toward women, we find no reasonable justification for the bishops’ position against women’s freedom of conscience. We also discovered that revelation does not belong exclusively to the bishops; truth continues to be revealed to all human consciences, and true freedom does not allow for coercion/castigation of dogmatic import. We advocate for women’s ability to openly discuss their struggles to meet their reproductive condundra and to deconstruct their sexual stereotypes in mental health therapy. We provide crucial recommendations to augment choices for women’s reproduction condundra, and incite the need for new epistemic frameworks to address the complexity of female sexuality.
Computer Aided Call for Tenders: A Tool for Software Bidding  [PDF]
Jorge Hochstetter, Carlos Cares
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.77055
Abstract:

Under a broad comprehension of Software Engineering, it is preferred the term software life cycle instead of just software production. The reason is that cycle starts at software conception and stops when the software is relegated. Given contemporary companies’ market strategies of focusing on their competitive advantages, most of them have externalized their software production to outsourced services. Therefore, the call for software tenders has become a common step in the software life cycle. In this paper, we present a tool which aids non-experts to specify call for software tenders. The motivation was Chile situation of most of rural and semi-urban city halls which do not have engineering teams to build call for software tenders. We describe the problem in terms of lack of competitiveness and empty biddings generated by low quality calls for tenders. As a second step, we show the technical considerations to develop the proposed tool and its features. We include an initial tool perception from a first group of users.
