    The project seeks that all preferential processes comply 100% with the purpose for which they were created, which is promoting the micro and small entrepreneurs originally from where it is to make the purchase, delivery or performance of service the work. We will be able to confirm address information, financial statements, the volume of assets in a truthful and provide us the Internal Revenue Service which is responsible for checking the veracity of them. For these processes of engagement which are very attractive to providers as an opportunity to be awarded is very high, overlooking the fact that manipulate their information by making false information is grounds for suspension of the National Register of Suppliers. In this way our system of control that will optimize the savings and especially the participation of micro and small entrepreneurs and artisans, because processes and contribution minor there is a marked preference for this group of suppliers. The initial investment of this project is 8840 because we only have to equip the space you already have the National Institute of Public Procurement within its administrative offices in the city of Quito

    Treatment of dogs with compensated myxomatous mitral valve disease with spironolactone-a pilot study

    Spironolactone improves outcome in dogs with advanced myxomatous mitral valve disease (MMVD). Its efficacy in preclinical MMVD is unknown. The hypothesis was the administration of spironolactone to dogs with compensated MMVD demonstrating risk factors for poorer prognosis will decrease the rate of disease progression. The aim was to provide pilot data to evaluate preliminary effects and sample size calculation for a definitive clinical trial

    Aim: To compare the type, number of procedures and working time of dental treatment provided under dental general anesthesia (DGA) in healthy and medically compromised/developmentally disabled children (MCDD children). Design: This cross-sectional prospective study involved 80 children divided into two groups of 40 children each. Group 1 consisted of healthy and Group 2 consisted of MCDD children. Results: Healthy children needed more working time than MCDD children, the means being 161±7.9 and 84±5.7 minutes, respectively (P= 0.0001). Operative dentistry and endodontic treatments showed a significant statistical difference (P= 0.0001). The means of procedures were 17±5.0 for healthy children and 11±4.8 for MCDD children (P= 0.0001). Conclusions: Healthy children needed more extensive dental treatment than MCDD children under DGA. The information from this sample of Mexican children could be used as reference for determining trends both within a facility as well as in comparing facilities in cross-population studies

    The top-quark mass in SU(5)xU(1) supergravity

    We show that the currently experimentally preferred values of the top-quark mass (\ie, 130\lsim m_t\lsim180\GeV) are naturally understood in the context of string models, where the top-quark Yukawa coupling at the string scale is generically given by λt=O(g)\lambda_t={\cal O}(g), with gg the unified gauge coupling. A detailed study of the Yukawa sector of SU(5)×U(1)SU(5)\times U(1) supergravity shows that the ratio of the bottom-quark to tau-lepton Yukawa couplings at the string scale is required to be in the range 0.7\lsim\lambda_b/\lambda_\tau\lsim1, depending on the values of mtm_t and mbm_b. This result is consistent with SU(5)×U(1)SU(5)\times U(1) symmetry, which does {\em not} require the equality of these Yukawa couplings in the unbroken symmetry phase of the theory. As a means of possibly predicting the value of mtm_t, we propose a procedure whereby the size of the allowed parameter space is determined as a function of mtm_t, since all sparticle and Higgs-boson masses and couplings depend non-trivially on mtm_t. At present, no significant preference for particular values of mtm_t in SU(5)×U(1)SU(5)\times U(1) supergravity is observed, except that high-precision LEP data requires m_t\lsim180\GeV.Comment: latex, 10 pages, 4 figures (included), CERN-TH.7138/94, CTP-TAMU-05/9
