Measurement of the ratios of the Z/gamma*+ >= n jet production cross sections to the total inclusive Z/gamma* cross section in p(p)over-bar collisions at root s=1.96 TeV

We present a study of events with Z bosons and associated jets produced at the Fermilab Tevatron collider in p p collisions at a center of mass energy of 1.96 TeV The data sample consists of nearly 14000 Z/gamma* -> e(+)e(-) candidates corresponding to an integrated luminosity of 0.4 fb(-1) collected with the D circle divide detector. Ratios of the Z/gamma*+ >= n jet cross sections to the total inclusive Z/gamma* cross section have been measured for n = 1-4 jets, and found to be in good agreement with a next-to-leading order QCD calculation and with a tree-level QCD prediction with parton shower simulation and hadronization.

Aspectos da organografia e anatomia foliar do amendoim: genótipos so-53 e so-909

Estudos morfológicos foliares foram efetuados em dois genótipos de amendoim (Arachis hypogaea L.), do grupo Valência, completando informações contidas em trabalhos anteriores. O amendoim, importante cultura mundial, possui o Brasil como centro de origem e dispersão de suas espécies. Nenhuma pesquisa havia sido realizada em organografia nem em anatomia foliar, com genótipos em cultivo no País. O genótipo SO-53 ('Tatu') é suscetível às mais relevantes moléstias fúngicas foliares, ocupando a maior área do amendoim cultivado no Brasil. O SO-909 (PI-259747) tem sido freqüentemente citado como fonte de resistência às moléstias fúngicas foliares, em trabalhos de fitopatologia. Medições macroscópicas, com o uso de paquímetro, bem como observações microscópicas, através de fotomicroscópio, foram efetuadas. Um estudo organográfico foi executado com as folhas de plantas de campo, bem como o estudo anatômico, com o uso de lâminas semipermanentes, mediante desenhos esquemáticos e fotomicroscópio. Os idioblastos encontrados nos folíolos foram divididos em três tipos, de acordo com a presença de tanino, mucilagem ou cristal. Os mucilaginosos foram separados em dois tipos, aparecendo os longos somente na superfície adaxial do limbo foliolar, e os curtos, similares às células epidérmicas, em seção paradérmica em ambas as faces do limbo foliolar. Os pêlos foram separados em três tipos, de acordo com o tamanho: os longos, os curtos e os muito curtos. Todos têm de uma a quatro células basais e uma longa apical. As cerdas², presentes nos dois genótipos, foram classificadas em dois tipos, também conforme o tamanho: as grandes, observadas visualmente, presentes sobretudo na bainha, e as curtas, ao longo da margem foliolar, ambas multicelulares. Algumas características morfológicas, como a presença e freqüência de pêlos; a forma da terminação do sulco na inserção adaxial do pecíolo-raque; a freqüência de cerdas e a espessura da lâmina foliolar, podem ser utilizadas na caracterização dos genótipos de amendoim. A menor espessura dos folíolos e a presença de espaços aeríferos na epiderme da face abaxial do limbo foliolar podem ser correlacionadas à suscetibilidade a determinadas moléstias fúngicas foliares do 'Tatu'.

Survey of the nutritional recommendations and management practices adopted by feedlot cattle nutritionists in Brazil

Thirty-three feedlot cattle nutritionists were surveyed to evaluate the management practices and nutritional recommendations adopted by feedlots in Brazil. The web-based survey consisted of 81 questions that included: general information (n = 10); general commodity information (n = 15); use of coproducts (n = 5), roughage source and level (n = 5); adaptation methods (n = 7); feed mixers (n = 6); feeding management (n = 6); cattle management and type of cattle fed (n = 13); formulation practices (n = 9); information resources used for nutritional recommendations (n = 2); and additional questions (n = 3). In total, the 33 nutritionists were responsible for approximately 2,658,000 animals, and moreover, 65.5% of those participants had clients that feed less than 5000 animals yearly. Corn was the primary source of grain used in feedlot diets (87.9%) and cracking was the primary processing method recommended by nutritionists (57.6%). The average concentrate and roughage inclusion in finishing diets was 79.0% and 21.0%, respectively. The main challenges faced by nutritionists are the lack of available and precise equipment and lack of trained employees with respiratory diseases as the main health problem. This survey of nutrition and management practices should aid in the development of research for the feedlot industry in Brazil and similar tropical climates, as well as provide data to facilitate the broader application of future NRC models.

Rui Barbosa: mito, memória e esquecimento

The remembrance of Rui Barbosa has always involved the maintenance of myths fabricated during his lifetime while a reappraisal of his intellectual, literary and political dimensions has been forwarded. Current essay discusses from several bibliographical samples on Brazilian social thought the manner the memory of the lawgiver from Bahia has been appropriated civically and intellectually. A qualitative and quantitative contrast was established between Barbosa’s works published and referred to and those by Joaquim Nabuco, Sílvio Romero and Gilberto Freyre. Oscillations in the evaluation of Barbosa’s works occurred during the 20th century that brought about a decrease in their value and about the memory on the historical subject.

Usefulness of vaginal cytology tests in women with previous hysterectomy for benign diseases: assessment of 53,891 tests

Objective. To assess the value of vaginal screening cytology after hysterectomy for benign disease.Methods. This cross-sectional study used cytology audit data from 2,512,039 screening tests in the metropolitan region of Campinas from 2000 to 2012; the object was to compare the prevalence of abnormal tests in women who had undergone a hysterectomy for benign diseases (n = 53,891) to that of women who had had no hysterectomy. Prevalence ratios (95% confidence intervals, 95% Cl) were determined, and chi-square analysis, modified by the Cochrane-Armitage test for trend, was used to investigate the effects of age.Results. The prevalence of atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL), and high-grade squamous intraepithelial lesion or squamous-cell carcinoma (HSIL/SCC) was 0.13%, 0.04% and 0.03%, respectively, in women who had undergone hysterectomy, and 0.93%, 0.51% and 0.26% in women who had not undergone hysterectomy. The prevalence ratios for ASC, LSIL and HSIL/SCC were 0.14(0.11-0.17), 0.08 (0.06-0.13) and 0.13 (0.08-020), respectively, in women with a hysterectomy versus those without. For HSIL/SCC, the prevalence ratios were 0.09 and 029, respectively, for women <50 or >= 50 years. The prevalence rates in women with a previous hysterectomy showed no significant variation with age.Conclusion. The prevalence rates of ASC, LSIL and HSIL/SCC were significantly lower in women with a previous hysterectomy for benign disease compared with those observed in women with an intact uterine cervix. This study reinforces the view that there is no evidence that cytological screening is beneficial for women who have had a hysterectomy for benign disease. (C) 2015 Elsevier Inc.

Metabolic investigation of patients with staghorn calculus: is it necessary?

To evaluate the prevalence of metabolic disorders in patients with staghorn calculi treated at the Regional Center of Lithiasis Metabolic Studies in central region of Såo Paulo State, Brazil. Between February 2000 and February 2008, 630 patients with urinary calculi were evaluated in the lithiasis outpatient clinic. Thirty-seven of them had staghorn calculi (35 women and 2 men). The inclusion criteria for the metabolic investigation included the absence of urological manipulation 30 days before the examination, negative urine culture and creatinine clearance > 60 mL/min. The protocol for metabolic investigation consisted of qualitative search for cystinuria. Two non-consecutive 24-hour urine samples collected to measure calcium, phosphorus, uric acid, sodium, potassium, magnesium, oxalate and citrate, and serum calcium levels, phosphorus, uric acid, sodium, potassium, magnesium, chloride, parathormone and urine pH. Among patients with lithiasis, 5.9% (37/630) had staghorn calculus and in 48.6% (18/37) were diagnosed with urinary infection. The females were predominant for 94.5% of cases. The calculi were unilateral in 31 of cases and bilateral in six. Metabolic abnormalities were found in 68.2% of patients with hypercalciuria (64.2%) and hypocitraturia (53.3%) being the most common disorders. The presence of metabolic disorders in nearly 70% of patients with staghorn calculus reinforces the necessity for evaluation of these patients. The diagnosis and treatment of identified metabolic abnormalities can contribute to the prevention of recurrent staghorn calculi.
