Quantum Corrections to Nucleation Rates
G. C. Marques,Rudnei O. Ramos
Physics , 1992,
Abstract: In this paper we show how to compute in a consistent way nucleation rates in field theory at finite temperatures, with metastable vacuum. Using the semiclassical approach in field theory at finite temperature we show that the prefactor term can be calculated explicitly (in the thin-wall approximation) and that the same provides exponential finite temperature quamtum corrections to nucleation rates, when fluctuations around the bubble field configuration are considered.
Jointly Optimal Sensing and Resource Allocation for Multiuser Overlay Cognitive Radios
Luis M. Lopez-Ramos,Antonio G. Marques,Javier Ramos
Computer Science , 2012,
Abstract: Successful deployment of cognitive radios requires efficient sensing of the spectrum and dynamic adaptation of the available resources according to the sensed (imperfect) information. While most works design these two tasks separately, in this paper we address them jointly. In particular, we investigate an overlay cognitive radio with multiple secondary users that access orthogonally a set of frequency bands originally devoted to primary users. The schemes are designed to minimize the cost of sensing, maximize the performance of the secondary users (weighted sum rate), and limit the probability of interfering the primary users. The joint design is addressed using dynamic programming and nonlinear optimization techniques. A two-step strategy that first finds the optimal resource allocation for any sensing scheme and then uses that solution as input to solve for the optimal sensing policy is implemented. The two-step strategy is optimal, gives rise to intuitive optimal policies, and entails a computational complexity much lower than that required to solve the original formulation.
The Total Amount of Energy Delivered by A Brazilian Hospital Catering does not Meet Patient Requirements as Measured by Indirect Calorimetry  [PDF]
Carolina Ferreira Nicoletti, Tatiana Pereira Lima, Roberta Deh Souza Santos, Nancy Yukie Yamamoto Tanaka, Vivian Marques Suen, Julio Sergio Marchini, Carla Barbosa Nonino
Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.22008
Abstract: The literature is controversial regarding the dietary recommendations for hospitalized patients in Brazil. Objective: We aimed to determine whether the energy content of the diet for hospitalized patients met their energy requirements measured by indirect calorimetry. Methods: Cross-sectional study conducted on adult hospitalized patients of both sexes. The prescription food was checked by reading the charts. Nutritional status was evaluated on the basis of weight, abdominal circumference (AbC), arm circumference (AC), body mass index and waist/hip ratio (WHR). The resting energy requirements of the patients were determined by indirect calorimetry. The diets offered were collected on 3 random non-consecutive days. Total nitrogen, lipid, water, ash and carbohydrate content of the menus were determined. Patients receiving a general or low-sodium diet by the oral route participated in the study. The Student T test was used to analyze the differences in energy expenditure between individuals. The association between gender and percent adequacy of the diet was calculated by the Fisher exact test. The level of significance was set at p < 0.05. Results: We studied 46 adult patients of both genders (29 women and 17 men) aged 45 ± 16 years. Anthropometric evaluation re-vealed a mean weight of 72 ± 26 kg, BMI of 28 ± 10 kg/m². 78% of the patients received energy above their require-ments, with this value increasing to 82% when obese patients were excluded. Conclusion: Since the hospital diet is an important and often vital resource for the recovery of patients and in view of the high prevalence of undernutrition or obesity, it is fundamental to adjust it to the intra-hospital reality.
Effect of Carbon Fillers in Ultrahigh Molecular Weight Polyethylene Matrix Prepared by Twin-Screw Extrusion  [PDF]
Luiz Felipe M. Rocha, Suellem B. Cordeiro, Leonardo C. Ferreira, Flávio James H. Ramos, Maria de Fátima Marques
Materials Sciences and Applications (MSA) , 2016, DOI: 10.4236/msa.2016.712066
Abstract: Oxidized (GO) and expanded (G-Exp) graphite were employed to prepare composites with ultrahigh molecular weight polyethylene (UHMWPE) matrix using masterbatches of polyethylene with different compositions. The materials and a blend of UHMWPE/HDPE were prepared by extrusion and their properties were evaluated. The effect of carbon fillers on the crystalline structure, thermo dynamic-mechanical (DMTA) and thermal properties (melting and crystallization temperatures) of the composites were discussed. The thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) measurements showed that the addition of masterbatch with GO and G-Exp significantly increased the crystallite size of composites, increasing the temperatures of melting, degradation, glass transition and the degree of crystallinity of polyethylene. DMTA analysis indicated the storage and loss moduli of composites in relation to neat UHMWPE, the blend and UHMWPE/composites. SEM micrographs showed a flatter, continuous and uniform surface meaning a compact lamellar structure. The present work resulted in interesting findings on the effects of GO on the crystalline structures, mechanical and thermal properties of UHMWPE, which can lead to generalizations useful for future work.

Revista Dental Press de Ortodontia e Ortopedia Facial , 2005, DOI: 10.1590/S1415-54192005000400006
Abstract: the orthodontic treatment strategy in crowded cases has usually been oscillated among no extraction and premolars' extractions. in certain situations the choice for an alternative or another would bring negative consequences. the extraction of a lower incisor in well selected cases represents an efficient approach, although little attention has been given to this kind of therapy in the literature. however, the correct indication must be evaluated by the orthodontist, who needs to know the peculiarities related to this treatment modality. in this sense, the aim of this work is to approach in a systematic way the several clinical aspects related with this therapeutic modality, illustrating its applicability through the presentation of treated cases.
