Field test on pile tip resistance of closed-end jacked pipe pile penetrating into layered foundation

In the layered soil foundation mainly composed of silty clay and silty clay, test piles with full cross-section pressure sensors installed at the end of piles are used to continuously and intensively collect pile tip resistances in the whole penetrating process with high density. throughout the entire process. According to the pile tip resistance curves of multiple penetration strokes, the change stage of the initial penetration of the pile tip resistance into the soil layer and the change stage of continuous penetration into the same soil layer are defined, which are divided into linear steep increase segments, nonlinear ramp segments, and platform segments, nonlinear slow-down section, linear steep drop section. When the pile end continuously penetrates through the interface of multiple soil layers, the change stage of the pile end resistance lacks a linear steep increase section compared with the initial penetration soil layer. The initial value of the steep drop of the previous stroke is close to the final value of the steep rise of the latter stroke, which can reflect the limit of the elastic compression of the soil, and is calculated by the average value of Qc, and is used as the pile foundation design. The pile tip resistance curve during the pile sinking process is similar to the static penetrating Qc curve. The maximum tip resistance of every layer in the layered soil is linear with the Qc value of the static penetrating probe and the average number of standard penetrations. Analysis of this situation found that the residual end-resistance after restoration was linearly related to the Qc value of cone penetration test(CPT) and the N value of standard penetration test(SPT). The fitting formula of elastic limit pile end resistance and ultimate pile tip resistance and residual tip resistance are put forward; and the fitting formula of ultimate pile tip resistance is more accurate than that of empirical parameter method, static cone penetration method and limit equilibrium theory.

Climate and the Myracrodruon urundeuva Allemão seed production

The seed physiological quality is related with climate variation during development. Thus, the aim of this study was to determinate the relation among climatic factors and germination of M. urundeuva seeds in different growing seasons and to predict the germination according to the climatic scenarios. Seeds from 14 crop seasons (2005 to 2018) and climatic data from the ‘Bebedouro’ weather station (Embrapa Semiarid) were used to determine the influence of climatic conditions on the vegetative, female and male flowers and the fruiting of M. urundeuva. The simple linear correlation and the multiple linear regression model were applied to determine the influence of climatic elements on the production of M. urundeuva seeds. The multivariate calibration model was developed using the previous selection of variables by the algorithm of successive projections. From the mathematical model, the germination of M. urundeuva seeds was predicted according to climate change, as provided by the IPCC. Seed germination showed a significant difference between harvests. Through the correlation it was observed that the temperature correlated negatively with all phenological phases of M. urundeuva. The quality of M. urundeuva seeds is related to the maximum, average and minimum temperature, average and minimum humidity, and precipitation. These climate variables during the different phenological phases of M. urundeuva affect the physiological quality of the seeds, and, in climate change scenarios, there will be a reduction in the seed production of this species. O clima e a produção de sementes de Myracrodruon urundeuva Allemão RESUMO A qualidade fisiológica das sementes está relacionada às variações climáticas durante o seu desenvolvimento. Assim, o objetivo deste trabalho foi determinar a relação entre os elementos climáticos e a germinação de diferentes safras de sementes de M. urundeuva, bem como prever a germinação frente aos cenários climáticos. Foram utilizadas sementes de 14 safras (2005 a 2018) e os dados climáticos da estação meteorológica de Bebedouro, pertencente a Embrapa Semiárido, para determinar a influência das condições climáticas nas fases vegetativa, flores femininas e masculinas e da frutificação de M. urundeuva. A correlação linear simples e o modelo de regressão linear múltipla foram aplicados para determinar a influência dos elementos climáticos na produção de sementes de M. urundeuva. O modelo de calibração multivariado foi desenvolvido empregando a seleção prévia de variáveis pelo algoritmo das projeções sucessivas. A partir do modelo matemático realizou-se a previsão da germinação de sementes de M. urundeuva frente às mudanças climáticas, previstas pelo IPCC. A germinação das sementes apresentou diferença significativa entre as safras. Por meio da correlação observou-se que a temperatura correlacionou negativamente com todas as fases fenológicas da M. urundeuva. A qualidade das sementes de M. urundeuva está relacionada com a temperatura máxima, média e mínima, umidade média e mínima, e com a precipitação. Essas variáveis de clima durante as diferentes fases fenológicas de M. urundeuva afetam a qualidade fisiológica das sementes, sendo que, em cenários de mudanças climáticas, ocorrerá uma redução na produção de sementes desta espécie.Palavras-chave: aroeira-do-sertão, mudanças climáticas, germinação.

PREVALENCE OF ASYMPTOMATIC BACTERIURIA AMONG WOMEN WITH DIABETES MELLITUS - A PROSPECTIVE CROSS-SECTIONAL STUDY

Background: There are many studies demonstrating the risk factors of asymptomatic bacteriuria (ASBU) in diabetic women. ASBU is a well-established risk factor for frequent urinary tract infections (UTIs) in women, and the risk factors that predispose diabetic women to ASBU has to be further evaluated. Aim: To estimate the prevalence of asymptomatic bacteriuria among women with diabetes mellitus .To verify if there is a correlation between bacteriuria and the duration of diabetes and also the correlation between bacteriuria with the metabolic control of diabetes. Materials And Methods: Patients who were admitted in Sree Mookambika Institute of Medical Sciences, Kulasekharam from February 2019 to November, 2020 were included in our study. Two hundred women with diabetes mellitus were enrolled in the study. A control group of 75 healthy women were randomly selected without diabetes was also evaluated in the same period.All relevant clinical information, data was collected. Patients were categorised into variables and mean, SD, Levene’s test of homogeneity of variance, linear regression was calculated. Results: 200 diabetic women were included in our study and 75 healthy women were selected as control. 150 patients were included in the study out of which 95 were males and 55 were females 40% had unstable Angina, 7% had NSTEMI and 53% had STEMI. prevalence of anaemia was 50% of the study population. Anaemia varied according to gender and was more in women 70.9% when compared to men 27.3%. Anaemia was also found to be higher in higher age groups and was more in patients with associated co morbidities such as chronic kidney disease,hypothyroidism and diabetes . Anaemia patients were also found to have more incidence of unstable angina when compared to other forms of ACS. The most common anaemia found was Microcytic hypochromic iron deficiency anaemia 32%. Out of those with iron deficiency, upper GI bleed was the most common cause in our patients. Triple Vessel Disease (TVD) patients were also found to have more incidence of anaemia than those with DVD and SVD. Conclusion: Urinary tract infection is one of the major disease burden for many patients having diabetes mellitus. Asymptomatic bacteriuria (ASB) is several-fold more common among diabetic women than healthy women. The risk of asymptomatic bacteriuria increases with increasing age. The duration of diabetes mellitus has significant correlation with development of asymptomatic bacteriuria among diabetic women. A significant impairment of metabolic control of diabetes shows an overall increase in the risk of developing asymptomatic bacteriuria. Keywords: Asymptomatic Bacteriuria, Diabetic Women, UTI

Modelación preliminar del flujo subterráneo en un sector de la cuenca inferior del arroyo del Azul (Buenos Aires, Argentina)

Se contruyó un modelo de flujo subterráneo, de carácter distribuido, con entradas y parámetros uniformes para todo el dominio de modelación. Este abordaje simplificado se realizó con el fin de caracterizar procesos generales y ajustar el modelo conceptual preliminar en el área de llanura del arroyo del Azul. Se propusieron metodologías a fin de completar las series discontinuas de niveles freáticos que fueron utilizados como condición de borde aguas arriba seleccionando una regresión lineal entre anomalías diarias de diferencias entre precipitación y evapotranspiración potencial con un retardo semanal con resultados de ajuste satisfactorios. Se consideraron como parámetros globales de calibración la transmisividad del acuífero, el coeficiente de almacenamiento, un coeficiente de recarga, una profundidad crítica para la evapotranspiración y un coeficiente de forma para la curva evapotranspiración vs. profundidad freática. Los coeficientes de eficiencia de Nash-Sutcliffe entre niveles modelados y observados en 6 pozos de control oscilaron entre 0.58 y 0.72. Tras la calibración, se concluyó que los parámetros obtenidos permiten una representación satisfactoria de la evolución de los niveles freáticos en los pozos de observación y de los patrones espaciales de las isofreáticas. Se pone en evidencia el rol prominente del proceso de evapotranspiración, el cual impacta directamente en el acuífero, representando una salida relevante del sistema. En el período de simulación de 43 meses, de características levemente secas, la recarga constituyó el 17 % de la precipitación, el 87 % de la misma retornó a la atmósfera como evapotranspiración, y el acuífero abastecería el 12.7 % de la evapotranspiración potencial del período. Se considera que la modelación simplificada permitió una aceptable representación del comportamiento del acuífero freático.

Development of rotational pulse-echo ultrasonic propagation imaging system capable of inspecting cylindrical specimens

A rotational pulse-echo ultrasonic propagation imager that can inspect cylindrical specimens for material nondestructive evaluations is proposed herein. In this system, a laser-generated ultrasonic bulk wave is used for inspection, which enables a clear visualization of subsurface defects with a precise reproduction of the damage shape and size. The ultrasonic waves are generated by a Q-switched laser that impinges on the outer surface of the specimen walls. The generated waves travel through the walls and their echo is detected by a Laser Doppler Vibrometer (LDV) at the same point. To obtain the optimal Signal-to-Noise Ratio (SNR) of the measured signal, the LDV requires the sensed surface to be at a right angle to the laser beam and at a predefined constant standoff distance from the laser head. For flat specimens, these constraints can be easily satisfied by performing a raster scan using a dual-axis linear stage. However, this arrangement cannot be used for cylindrical specimens owing to their curved nature. To inspect the cylindrical specimens, a circular scan technology is newly proposed for pulse-echo laser ultrasound. A rotational stage is coupled with a single-axis linear stage to inspect the desired area of the specimen. This system arrangement ensures that the standoff distance and beam incidence angle are maintained while the cylindrical specimen is being inspected. This enables the inspection of a curved specimen while maintaining the optimal SNR. The measurement result is displayed in parallel with the on-going inspection. The inspection data used in scanning are mapped from rotational coordinates to linear coordinates for visualization and post-processing of results. A graphical user interface software is implemented in C++ using a QT framework and controls all the individual blocks of the system and implements the necessary image processing, scan calculations, data acquisition, signal processing and result visualization.

The Epidemiology of Aggression and Associated Factors among Iranian Adult Population: A National Survey.

Background: This survey was conducted to determine the level of aggression among the Iranian adult population and underlying predisposing factors. Study design: A cross-sectional study. Methods: This cross-sectional study included 10,957 participants, involving 23 out of the 31 provinces of Iran in 2019. The outcome of interest was aggression, evaluated by the Buss & Perry aggression questionnaire. The association between aggression and 34 demographic, behavioral, social, and cultural characteristics was assessed using simple and multiple linear regression. Results: The overall mean (SD) score of aggression was 77.10 (22.53). Based on the severity of aggression, the participants were categorized into four groups as follows: 2,464 (23.1%) nonaggressive, 4,692 (43.9%) mild, 3,071 (28.8%) moderate, and 454 (4.2%) severe aggressive. Aggression was more likely to occur in people with the following characteristics: younger ages, having several siblings, lower ranks of birth, having an intimate friend of the opposite sex, having an aggressive father/mother, history of parental divorce, interest in watching action/porn movies, listening to music, history of escape from home/school, using neuropsychiatric drugs, using illicit drugs, history of suicidal thoughts/attempt, and family conflict and hostility. Aggression was less likely to occur with the following characteristics: reading, regular physical exercise, the ability to control anger, regular prayer, adherence to avoid lying, respect to other people's rights, sexual satisfaction, and attachment to parents. Conclusions: A majority of the population has some degree of aggression. Aggression is a multifactorial behavior corresponding with several demographical, social, cultural, and religious factors, some of which back to early childhood events.
