Bazhenov horizon of Siberia (Tithonian – Lower Berriasian): tectonic and hydrodynamic conditions of sedimentation

The new model of the sedimentation of the Bazhenov Formation, on which black shale accumulated on relative elevation – a shallow-marine hilly plateau, agrees well with the results of a general paleogeographic analysis of the Bazhenov horizon of Siberia. In addition to the favorable conditions for the accumulation and fossilization of organic matter, the most important conditions for the formation of a unique Bazhenov suite are the multiplicity of nutrient sources, their constant flow, and the capture of almost all the terrigenous material in the flow basins of the Ural-Khatanga strike-slip. Judging by the presence of incisions and the distribution of facies in the system of strke-slip basins, a sea current from the Arctic Ocean operated on the territory of the YeniseiKhatanga trough. Periodic changes of the Arctic runoff were probably synchronous episodes of tectonic activation in the divergent shear zone. Rising sea levels led to flooding of the hilly‑lake South-Taimyr coastal basin and increasing the flow of sedimentary material from it. During the transgressions, nutrients were removed from flooded plains of South Taimyr. At the same time, the transgressions “locked” the flow from the Vilyui alluvial-lake basin. During regressions, on the contrary, the runoff of sedimentary material and biophilic elements from Vilyui sharply increased.

Patient Preferences in Subglottic Stenosis Treatment: A Discrete Choice Experiment.

Objectives Subglottic stenosis can be addressed with several different surgical techniques, but patient preferences for these treatment modalities are poorly understood. Economic methods are increasingly being used to understand how patients make decisions. The objective of this pilot study was to assess preferences in subglottic stenosis treatment using patient-centric stated preference techniques. Study Design Discrete choice experiment (DCE). Setting Academic research facility. Subjects and Methods A computer-based DCE was administered in a monitored setting to volunteers from the general population. Signs and symptoms of subglottic stenosis were described, and participants were asked to imagine they had subglottic stenosis. Hypothetical treatments were offered, with 5 systematically varied attributes: need for external incision, length of hospital stay, postoperative voice quality, likelihood of repeat procedures, and risk of complication. A conditional logistic model was used to assess the relative attribute importance. Results In total, 162 participants were included. Attributes with the greatest impact on decision making included potential need for repeat procedures (importance 30.2%; P < .001), amount of operative risk (importance 28.1%; P < .001), and postoperative voice quality (importance 27.7%; P < .001), whereas presence of incision (importance 5.0%; P = .001) was less important, and hospital stay was not (importance 9.0%; P = .089). Based on aggregate responses for these attributes, the model demonstrated that most participants (80.4%) would prefer endoscopic surgery for subglottic stenosis as opposed to open tracheal resection (19.6%). Conclusion In this pilot population, most participants preferred voice-sparing, low-risk procedures as treatment for subglottic stenosis, consistent with an endoscopic approach, even if multiple procedures were required.

Propagação de Camellia sinensis: efeito do genótipo, estaca, substrato, recipiente e ácido indolbutírico

Tem sido relatado que as estacas de Camellia sinensis possuem baixa capacidade de emitir raízes, motivando assim a realização de estudos básicos para otimização do processo de propagação por estacas. Assim sendo, o presente trabalho objetivou quantificar o potencial rizogênico de diferentes genótipos e o efeito da posição da estaca no ramo e incisão na base, do substrato, tamanho do recipiente e ácido indolbutírico no enraizamento de estacas semi-lenhosas dessa espécie. Para tal, foram coletados ramos dos genótipos IAC 259, F15 e Comum, em Pariquera-Açu-SP, no inverno de 2010. Em seguida, preparadas as estacas, contendo uma gema e uma folha, foram mantidas em viveiro com 70% de sombreamento. Estacas da posição basal e mediana dos ramos são as mais adequadas para estaquia devido a menor mortalidade e maior enraizamento. A injúria na base da estaca não afeta a mortalidade e o enraizamento das estacas, porém induz à formação de calo. Também não houve diferenças na mortalidade e no enraizamento das estacas quando as mesmas foram mantidas em recipiente de 50, 90 e 120 cm³. Comparado com vermiculita, areia e casca de arroz carbonizada, o solo foi o melhor substrato para estaquia, que na presença do ferimento, juntamente com o tratamento das estacas com 10 g L-1 de AIB promoveu a maior porcentagem de enraizamento. Todavia, ainda nessa condição a mortalidade média das estacas foi de 42%. O potencial de enraizamento do genótipo Comum foi superior ao do IAC 259 e F15.

Fatores maternos associados ao peso fetal estimado pela ultra-sonografia

to evaluate the effect of maternal, socioeconomic and obstetric variables, as well the presence of artery incisions in the 20th and 24th weeks on the fetal weight estimated at the end of pregnancy (36th week) in pregnant women attended by Programa Saúde da Família, in an inland town of the northeast of Brazil. a longitudinal study including 137 pregnant women, who have been followed up every four weeks in order to assess clinical, socioeconomic and obstetric conditions, including their weight. The uterine arteries were evaluated by Doppler in the 20th and 24th weeks, the fetal weight and the amniotic fluid index (AFI), determined in the 36th week. The initial maternal nutritional state has been determined by the body mass index (BMI), the pregnant women being classified as low weight, eutrophic, over weight and obese. Weight gain during gestation has been evaluated, according to the initial nutritional state, being classified at the end of the second and third trimester as insufficient, adequate and excessive weight gain. Analysis of variance was performed to evaluate the association of the fetal weight in the 36th week with the predictor variables, adjusted by multiple linear regression. an association between the fetal weight estimated in the 36th week and the mother's age (p=0.02), mother's job (p=0.02), initial nutritional state (p=0.04), weight gain in the second trimester (p=0.01), presence of incisions in the uterine arteries (p=0.02), and AFI (p=0.007) has been observed. The main factors associated to the fetal weight estimated in the 36th week, after the multiple regression analysis were: BMI at the pregnancy onset, weight gain in the second trimester, AFI and tabagism. in the present study, the fetal weight is positively associated with the initial maternal nutritional state, the weight gain in the second trimester and the volume of amniotic fluid, and negatively, to tabagism.
