Nobody doubts that he always received considerable voter support in the numerous elections held during his mandate. However, the integrity of the electoral system has come into question since the Presidential Recall Referendum. From then on, different sectors of society have systematically alleged electoral irregularities or biases in favor of the incumbent party. We have carried out a thorough forensic analysis of the national-level Venezuelan electoral processes held during the period to assess these complaints.

The second-digit Benford’s law and carpos statistical models of vote distributions, recently introduced in the literature, are reviewed and used in our case study. In addition, we discuss a investigaci method to detect irregular variations caelos the electoral roll. The outputs obtained from these election forensic tools are examined taking into account cualitaitva substantive context of the elections and referenda under study. Thus, we reach two main conclusions. Firstly, all the tools uncover anomalous statistical patterns, which are consistent with election fraud from onwards.

Although our results are not a concluding proof of fraud, they signal the Recall Referendum as a turning point in the integrity of the Venezuelan elections. Secondly, our analysis calls into question the reliability of the electoral register since We have carried out a thorough forensic analysis of the national-level Venezuelan electoral processes held during the — period to assess these complaints.

Relatively uniform-sized poly lactide-co-ethylene glycol PELA microspheres with high encapsulation efficiency were prepared rapidly by a novel method combining emulsion-solvent extraction and premix membrane emulsification. Briefly, preparation of coarse double emulsions was followed by additional premix membrane emulsification, and antigen-loaded microspheres were obtained by further solidification.

Under the optimum condition, the particle size was about 1 mum and the coefficient of variation CV value was Confocal laser scanning microscope and flow cytometer analysis showed that the inner droplets were small and evenly dispersed and the antigen was loaded uniformly in each microsphere when sonication technique crlos occupied to prepare primary emulsion.

Distribution pattern of PEG segment played important role on the properties of microspheres. Compared with triblock copolymer PLA-PEG-PLA, the diblock copolymer PLA-mPEG yielded a more stable interfacial layer at the interface of oil and water phase, and thus was more suitable to stabilize primary emulsion and protect coalescence of inner droplets and external water phase, resulting in high encapsulation efficiency On the other hand, solidification rate determined the time for coalescence during microspheres fabrication, and thus affected encapsulation efficiency.

Taken together, improving the polymer properties and solidification rate are considered as two effective strategies to yield high encapsulation. Invesgigacin of the bone injury remains a challenge in clinical practices. Recent progress in tissue engineering and therapeutic gene delivery systems have led to promising new strategies for successful acceleration of bone repair process.

Abstract Eight new species of DesmopachriaBabington, are described and illustrated from Brazil: From species of the Desmopachria reported in Sandovaal, D. A checklist of all Desmopachria recorded from Brazil is presented with notes about some of the localities. At the heart of the Christian experience lies the conviction that justice and freedom are szndoval to build communities where God’s love is authentically experienced by all.

Such conviction emerges as part of an intentional process of faith formation that begins at home and must be constantly nurtured throughout the life cycle. During the past decade, crack smoking has increased in Mexico among poor urban populations. Despite this increasing prevalence, little is known about the types of paraphernalia used and related sharing practices and physical harms.

Data come from in-depth semi-structured interviews and observations with current crack smokers in Mexico City. Findings reveal a complex, crack-smoking process in Mexico City that represents an interconnected structure of paraphernalia items and pipes that could contribute to detrimental health consequences.

Specifically, we identify essential paraphernalia items that make the smoking of crack possible; describe the home- made construction of two categories of pipes; and the sharing practices and physical harms associated with these paraphernalia. Results point towards a smoking process that is embedded in impoverished urban neighborhoods sustained by an accessible street-level crack market.


Discussed are the policy and intervention implications associated with reducing crack related health consequences in Mexico and other Latin American countries.

Enfocamos e discutimos principalmente os seguintes aspectos da fase impulsiva do evento: You Only Live Once: Although Latinos living in the United States are disproportionately affected by HIV, the development, implementation, and evaluation of HIV prevention, testing, and linkage to care interventions lag behind efforts occurring in other communities.

To address sociocultural barriers to testing, we developed a multilevel intervention. This study is a pilot evaluation casili,as the individual-level component of the intervention-animated video modules that address specific barriers to HIV testing common among foreign-born Latino men.

We conducted a survey assessing HIV risk and barriers to testing with a convenience sample of foreign-born Latino men in Carkos, MD, who had not tested cualitativw HIV within the past year. Intention to test in the next 3 months was measured before and after viewing an intervention module selected based on survey responses.

Of the participants who had previously tested for HIV, the mean time since their last test was 3. Study of the Local Horizon. Estudio del Sandovql Local. Estudo do Horizonte Local.

Pectate lyase affects pathogenicity in natural isolates of Colletotrichum coccodes and in pelA gene-disrupted and gene-overexpressing mutant lines. Hughes, the causal agent of black dot on potato and anthracnose on tomato, reduces yield and crop quality.

We explored the role of secreted pectate lyase PLa cell wall-degrading enzyme, in the aggressiveness of C. In vitro-cultivated highly aggressive isolates secreted immunologically detectable PL levels 6 h after transfer to ssndoval medium versus 12 h for mildly aggressive isolates, suggesting that secreted PL is a virulence factor. CcpelA gene-disrupted mutants showed reduced aggressiveness towards tomato fruits and impaired PL secretion and extracellular activity.

Conversely, overexpression of CcpelA in the Si isolate increased its aggressiveness and PL inestigacin.

Comparison of CcpelA cloned from isolates US and Si revealed that both encode identical proteins, but differ in their promoters. Bioinformatics swndoval for cis-acting elements suggested that the promoters of the US and Si isolates contain one and no AreA-binding site GATA boxrespectively.

AreA has been suggested to be involved in fungal aggressiveness; therefore, CcpelA may be a key virulence factor in C. Quantitative reverse transcriptase-polymerase chain reaction analyses confirmed the higher level of CcpelA transcript in isolate US versus Si Study of heat and salt transport processes in the Espinheiro Channel Ria de Aveiro.
