1. Investigation of hyperfine interactions in pure silicon and NTD silicon by means of perturbed angular γ-γ correlation spectroscopy / Investigação de interações hiperfinas em silício puro e silício NTD pela técnica de correlação angular gama-gama perturbada
In the present work, a microscopic investigation of hyperfine interactions in single crystal silicon samples was carried out by means of Perturbed Angular γ-γ Correlation technique (PAC), which is based in hyperfine interactions. In order to achieve these measurements, it was used 111In ->111Cd radioactive probe nuclei, which decay through the we

2. Cultura, políticas de desarrollo y turismo rural en el ámbito de la globalización
In this essay I analyze the new principles of what is called rural tourism in Spain. I examine the importance of this sector in relation to the new directions of globalization, inserting this phenomena within a larger process of the reconfiguration of the rural world. Designed at the European level and regulated by the Política Agraria Común (Common Agricu

3. Controle em destilação batelada : controle adaptativo e controle preditivo com modelo baseado em redes neurais artificiais
Separation processes are very important in chemical industries where batch distillation appears as one of its oldest processes. Over the last few years batch processing has received renewed attention because of the growing interest in the production of high-technology, high-value added chemical and biochemical products and also in environmental problems of i

4. Effect of Environmental pH on Morphological Development of Candida albicans Is Mediated via the PacC-Related Transcription Factor Encoded by PRR2
The ability to respond to ambient pH is critical to the growth and virulence of the fungal pathogen Candida albicans. This response entails the differential expression of several genes affecting morphogenesis. To investigate the mechanism of pH-dependent gene expression, the C. albicans homolog of pacC, designated PRR2 (for pH response regulator), was identi

5. Differential Activation of Guinea Pig Intrinsic Cardiac Neurons by the PAC1 Agonists Maxadilan and Pituitary Adenylate Cyclase-Activating Polypeptide 27 (PACAP27)
Pituitary adenylate cyclase-activating polypeptide (PACAP) evokes tachycardia followed by a larger cholinergic bradycardia in isolated guinea pig hearts. We used the selective PAC1 receptor agonist maxadilan and vasoactive intestinal polypeptide (VIP) to test the hypothesis that PACAP27-evoked tachycardia and bradycardia are mediated by VPAC and PAC1 recepto

6. Changes in translational yield regulate tissue-specific expression of beta-glucuronidase.
The number of beta-glucuronidase (GUS; beta-D-glucuronoside glucuronosohydrolase, EC 3.2.1.31) molecules per cell varies as much as 12-fold among mouse tissues. To identify the regulatory mechanisms responsible, estimates of the rates of GUS protein synthesis (ks) and degradation (kd) were obtained for six tissues in the B6.PAC-Gusn mouse strain, which carri
