Real wage rigidity and the new Phillips curve: the Brazilian case
Mazali, Antonio Alberto;Divino, José Angelo;
Revista Brasileira de Economia , 2010, DOI: 10.1590/S0034-71402010000300005
Abstract: the new keynesian phillips curve has been criticized for not explaining the short-run inflation-output gap trade-off. blanchard and galí (2007) introduced real wage rigidity and derived a trade-off between stabilizing inflation and the gap between actual and efficient output. this paper estimates the new phillips curve for the brazilian economy, computes short-run trade-off, analyzes real wage rigidity, and tests theoretical restrictions imposed by the model. the gmm estimations fit the data very well and all theoretical restrictions are satisfied. there is strong real wage rigidity and a high output-gap cost to stabilize inflation in the short run.
Geographical mortality patterns in Italy: A Bayesian analysis
Fabio Divino,Viviana Egidi,Michele Antonio Salvatore
Demographic Research , 2009,
Abstract: In this paper, we present a hierarchical spatial model for the analysis of geographical variation in mortality between the Italian provinces in the year 2001, according to gender, age class, and cause of death. When analysing counts data specific to geographical locations, classical empirical rates or standardised mortality ratios may produce estimates that show a very high level of overdispersion due to the effect of spatial autocorrelation among the observations, and due to the presence of heterogeneity among the population sizes. We adopt a Bayesian approach and a Markov chain Monte Carlo computation with the goal of making more consistent inferences about the quantities of interest. While considering information for the year 1991, we also take into account a temporal effect from the previous geographical pattern. Results have demonstrated the flexibility of our proposal in evaluating specific aspects of a counts spatial process, such as the clustering effect and the heterogeneity effect.
Pólipos endometriais
Nogueira, Antonio Alberto;
Revista Brasileira de Ginecologia e Obstetrícia , 2005, DOI: 10.1590/S0100-72032005000500010
Abstract: endometrial polyps are benign lesions, with a low potential of malignancy. in the reproductive period their diagnosis is established in symptomatic patients with abnormal uterine bleeding or infertility. postmenopausal women are mostly asymptomatic but in approximately one third of the cases there is an association with abnormal bleeding. they are more frequent after the menopause and risk factors of cancer of the endometrium have not been associated in the same way as risk for endometrial polyps, although they are hormone-dependent as in patients in use of tamoxifen, for instance. their definitive diagnosis is established by hysteroscopy-guided biopsy and their most effective treatment is hysteroscopic resection. polyps may recur after treatment. polypectomy is highly satisfactory after the menopause, is less successful in symptomatic women in the reproductive period and improves fertility rates in infertile women.
Two Loop R-Symmetry Breaking
Amariti, Antonio;Mariotti, Alberto
High Energy Physics - Phenomenology , 2008, DOI: 10.1088/1126-6708/2009/07/071
Abstract: We analyze two loop quantum corrections for pseudomoduli in O'Raifeartaigh like models. We argue that R-symmetry can be spontaneously broken at two loop in non supersymmetric vacua. We provide a basic example with this property. We discuss on phenomenological applications.

Abstract: cement-bonded particleboards of rubberwood were manufactured with four clones of hevea brasiliensis müll. arg. (rubberwood): ian 717, ian 873, gt 711 and avros 1301. boards of 450 x 450 x 13 mm were manufactured in a ratio of 1:4:1 (wood/cement/water), weight basis, with 1.4 g/cm3 density and 4% calcium chloride dihydrated - cacl2.2h2o as accelerator. the particles of four clones were tested in treated and untreated conditions, totaling eight treatments. in each treatment with four replicates, the physical and mechanical properties were evaluated according to astm d 1037 - 96a standard. overall, the best mechanical and physical results were obtained with the cement-bonded particleboard made with particles from clone avros 1301. rubberwood has shown to be "highly inhibitory" in the hydration test, however when cacl2 was added the inhibition index decreased and was classified as "low inhibitory". rubberwood is technically feasible to make cement-bonded particleboard.
Natural killer cells responsiveness to physical exercise: A brief review  [PDF]
Antonio Crisafulli, Filippo Tocco, Franco Melis, Raffaele Milia, Alberto Concu
Open Journal of Immunology (OJI) , 2013, DOI: 10.4236/oji.2013.34024
Abstract: Natural killer cells (NK) are a group of peripheral blood lymphocytes which display cytotoxic activity against a wide range of tumour cells. They are a consistent part of the inflammatory response that is activated when either internal or external injuries occur as they are able to synthesize perforins. An important role is played by NK cells in the host defence against tumours without expressing any antigen-binding recaptor in their membrane which, however, distinguish T and B lymphocytes. NK activity appears early in the immune response, thus providing immediate protection during the time required for the activation and proliferation of cytotoxic T lymphocytes and for their differentiation into functional cells. Even though much research regarding the effects of aerobic training exercise on NK cell numbers and function, there appears to be much controversy regarding its effect. NK cells are rapidly mobilized into circulation in response to acute exercise, most likely by increased shear stress and catecholamine-induced down-regulation of adhesion molecule expression. However, tissue injury and inflammation which often accompanies strenuous exercise have been associated to post-exercise NK cell suppression. Scientific evidence indicates exercise-induced changes in NK cell redistribution and function should be strongly influenced by stress hormones including catecholamines, cortisol and prolactin as well as by soluble mediators such as cytokines and prostaglandins. The role of exercise therapy in cancer patients and survivors rehabilitation is becoming increasingly important as it is thought to modulate immunity and inflammation. However, more knowledge about the effects of exercise on immune function in these patients is needed.
Osteomalacia no neoplásica en Colombia
Ca?as,Carlos Alberto; Iglesias,Antonio;
Acta Medica Colombiana , 2005,
Abstract: objective: to describe the characteristics of presentation of 20 patients with non-neoplasic osteomalacia in several hospitals in colombia. material and methods: this multi-center study was undertaken to describe the demographic, clinical, radiographic, biochemical and ethiological aspects of 20 patients with non-neoplasic osteomalacia. results: the patients' ages were 17-70 (mean age 40.6), 11 men and 9 women. the most common symptoms were muscle weakness (16/20), and muscle pain (16/20). the two symptoms were present in the same patients in 13 occasions (65%). the most common radiological characteristic was osteopenia, confirmed by bone densitometry. the most common biochemical findings were: hypocalcemia (14/20), normophosphatemia in 12 out of 20, and hypophosphaturia in 5. low levels of 1-25 (oh)2 vit d in one case. alkaline phosphatase was high in 18 cases. the biochemical alterations turned to normal levels after the treatment. conclusion: the general characteristics were not different from those reported in the medical literature. the osteomalacia is a rare condition, usually neglected when compared to other metabolic bone diseases and may be present with a wide variety of clinical and radiographic manifestations mimicking other musculoskeletal disorders. generally there is a delay of the diagnosis, thus generating a striking morbidity in patients.
Redu??o da for?a de reten??o e abertura de grampos a barra em "I" de Roach e sua correla??o
MUZILLI, Carlos Alberto;MUENCH, Antonio;
Revista de Odontologia da Universidade de S?o Paulo , 1999, DOI: 10.1590/S0103-06631999000200015
Abstract: the purpose of this research was to determine the retention drop of i-bar clasps, their possible opening during mechanical cycling and their correlation. two co-cr alloys were used and the design of clasps were: short-thin; short-thick; long-thin; long-thick. clasps were also partially covered or not with resin. measurements were made at the initial stage and after 20 thousand cycles. the results led to the following conclusions: the alloys presented similar retention drop; opening of the several types of clasps were similar, but retention drop was minor on long-thin clasp and major on short-thick ones; resin did not influence the opening of clasps but increased retention drop; correlation between retention drop and opening of clasps was not significant.
