The aim of this systematic review was to assess the optimal number of implants for removable reconstructions.

A critical appraisal of the legal framework governing the approval in microfinance Establishments within CEMAC

During the mid 80 19s and the early 90 19s the Banking sector of the CEMAC sub-region experienced crisis. This could be seen from the numerous liquidation of Banks within the sub-region during this period, microfinance establishments found a place as an alternative financial institution involved in the provision of savings and loans to the masses. The exercise of the activities of microfinance necessitates an application for approval form the monetary authority. Their potential managers and auditors must equally apply and obtain a license before functioning. After this approval has been obtained the microfinance establishment must register with the National Credit Council and the Trade and Personal Property Credit Register. // Durant les années 80 et au début des années 90 le secteur Bancaire de la sous-région CEMAC on vécue une crise, ceci pouvait ce voit par de nombreuse liquidation des Banques au sein de la sous-région pendant cette période. Les Etablissement de Micro finance ont trouve une place comme une institution financière alternative s’impliquant dans la fourniture de l’épargne et des prêts pour la masses. Mais l'exercice de l'activité de microfinance exige une demande d'agrément remise par l'autorité monétaire après confirmation de la commission bancaire. Mais avant que cet agrément soit remis, ils doivent fournir certain documents et informations. Les microfinances sont également oblige de fournir certaines documents et information s'il veut offrir un agence dans un du état membre de la CEMAC. Quand cette agrément est remise il sont les obligations administrative et professionnelle a remplir. Ceci consiste de s’inscrire auprès du Conseil National du Crédit et le Registre du Commerce et du Crédit Mobilier, adhérer a une Association Professionnelle, mais ils sont le choix adhérer à un réseau ou de poursuivre les activités indépendamment. L'autorité monétaire peut unilatéralement retrait la décision d'agrément pour un raison ou l'autre. Cependant, la décision de retrait de l'agrément est assujettir à un appel devant le conseil d'administration de la BEAC. La commission bancaire a prévu un ensemble de sanctions pour s'assurer que une personne ou établissement en défaut soit appelle en ordre. // Cameroon, Micro-finance, CEMAC, COBAC, Legislation

Strong Dynamical Heterogeneity and Universal Scaling in Driven Granular Fluids

Large-scale simulations of two-dimensional bidisperse granular fluids allow us to determine spatial correlations of slow particles via the four-point structure factor S-4 (q, t). Both cases, elastic (epsilon = 1) and inelastic (epsilon < 1) collisions, are studied. As the fluid approaches structural arrest, i.e., for packing fractions in the range 0.6 <= phi <= 0.805, scaling is shown to hold: S-4 (q, t)/chi(4)(t) = s(q xi(t)). Both the dynamic susceptibility chi(4)(tau(alpha)) and the dynamic correlation length xi(tau(alpha)) evaluated at the alpha relaxation time tau(alpha) can be fitted to a power law divergence at a critical packing fraction. The measured xi(tau(alpha)) widely exceeds the largest one previously observed for three-dimensional (3d) hard sphere fluids. The number of particles in a slow cluster and the correlation length are related by a robust power law, chi(4)(tau(alpha)) approximate to xi(d-p) (tau(alpha)), with an exponent d - p approximate to 1.6. This scaling is remarkably independent of epsilon, even though the strength of the dynamical heterogeneity at constant volume fraction depends strongly on epsilon.

Follicle flushing in monofollicular in vitro fertilization almost doubles the number of transferable embryos

Follicle flushing has been proved to be ineffective in polyfollicular in vitro fertilization. To analyze the effect of flushing in monofollicular in vitro fertilization we aspirated and then flushed the follicles in 164 cycles. Total oocyte yield/aspiration was 44.5% in the aspirate, 20.7% in the 1(st) flush, 10.4% in the 2(nd) flush and 4.3% in the 3(rd) flush. By flushing, the total oocyte yield increased (p < 0.01) by 80.9%, from 44.5 to 80.5%. The total transfer rate increased (p < 0.01) by 91.0%, from 20.1 to 38.4%. The results indicate that the oocyte yield and the number of transferable embryos can be increased significantly by flushing.

17β-estradiol protects 7-day old rats from acute brain injury and reduces the number of apoptotic cells

To test a possible neuroprotective activity of 17β-estradiol in the neonatal rat brain exposed to hypoxic-ischemia (controlled hypoxia after unilateral carotid artery ligation).

Liberal Nationalism: A Historical and Critical Analysis of Conceptions

At the end of the 20th century we live in a pluralist world in which national and ethnic identities play an appreciable role, sometimes provoking serious conflicts. Nationalist values seem to pose a serious challenge to liberal ones, particularly in the post-communist countries. Malinova asked whether liberalism must necessarily be contrasted with nationalism. Although nationalist issues has never been a major concern for liberal thinkers, in many countries they have had to take such issues into consideration and a form of 'liberalism nationalism' has its place in the history of political ideas. Some of the thinkers who tried to develop such an idea were liberals in the strict sense of the word and others were not, but all of them tried to elaborate a concept of nationalism that respected the rights of individuals and precluded discrimination on ethnic grounds. Malinova studied the history of the conceptualisation of nations and nationalism in the writings, of J.S. Mill, J.E.E. Acton, G. Mazzini, V. Soloviev, B. Chicherin, P. Struve, P. Miljoukov and T.G. Masaryk. Although it cannot be said that these theories form a coherent tradition, certain common elements of the different approaches can be identified. Malinova analysed the way that liberal nationalists interpreted the phenomenon of the nation and its rights in different historical contexts, reviewed the structure of their arguments and tried to evaluate this theoretical experience from the perspective of the contemporary debate on the problems of liberal nationalism and multiculturalism and recent debates on 'the national idea' in Russia.

Estimating the number of motor units using random sums with independently thinned terms

The problem of estimating the numbers of motor units N in a muscle is embedded in a general stochastic model using the notion of thinning from point process theory. In the paper a new moment type estimator for the numbers of motor units in a muscle is denned, which is derived using random sums with independently thinned terms. Asymptotic normality of the estimator is shown and its practical value is demonstrated with bootstrap and approximative confidence intervals for a data set from a 31-year-old healthy right-handed, female volunteer. Moreover simulation results are presented and Monte-Carlo based quantiles, means, and variances are calculated for N in{300,600,1000}.

Estimating the Number of Essential Genes in a Genome by Random Transposon Mutagenesis

We describe a Bayesian method for estimating the number of essential genes in a genome, on the basis of data on viable mutants for which a single transposon was inserted after a random TA site in a genome,potentially disrupting a gene. The prior distribution for the number of essential genes was taken to be uniform. A Gibbs sampler was used to estimate the posterior distribution. The method is illustrated with simulated data. Further simulations were used to study the performance of the procedure.
