Algorithm for cavity flow in a new-born goaf and experimental verification

Prevention and control measures of spontaneous combustion of coal and gas accumulation in a goaf require an accurate description of its gas flow state.However,the commonly used fluid dynamics in porous media is not suitable for the new-born goaf with fracture cavity combination,multi-scale,and large blocks.In this study,we propose a cavity flow algorithm to accurately describe the gas flow state in the new-born goaf.The genetic algorithm(GA)is used to randomly generate the binary matrix of a goaf caving shape.The difference between the gas flow state calculated by the lattice Boltzmann method(LBM)and the measured data at the boundary or internal measuring points of the real goaf is taken as the GA fitness value,and the real goaf caving shape and the gas flow state are quickly addressed by GA.The experimental model of new-born goaf is established,and the laser Doppler anemometry(LDA)experiment is carried out.The results show that the Jaccard similarity coefficient between the reconstructed caving shape and the real caving shape is 0.7473,the mean square error between the calculated wind speed and the LDA-measured value is 0.0244,and the R2 coefficient is 0.8986,which verify the feasibility of the algorithm.

Predominance of Multi-Drug Resistant <i>Klebsiella pneumonia</i>and Other Gram Negative Bacteria in Neonatal Sepsis in Equatorial Guinea

The study was conducted on new-born babies in whom septicemia was suspected, to determine the prevalence of bacterial strains isolated and their sensitivity to antimicrobial drugs. The study was carried out at La Paz Medical Center, Microbiology section, Malabo, Equatorial Guinea from August 2013 to October 2015. Out of 293 septicemia suspected cases, 29 (10%) blood cultures were positive, 28 with bacterial growth and 1 with growth of Candida sp. The mortality rate of neonates caused by Gram negative bacterial sepsis was 34.7%. Among the Gram negative bacteria (24 isolates), the most common types were Klebsiella pneumoniae (16 = 69.6%), followed by Escherichia coli (4 = 17.4%) and Acinetobacter species (4 = 17.4%). Four Gram positive bacteria were also isolated and identified all ascoagulase-negative staphylococci. All the Klebsiella pneumoniae isolates and Acinetobacter species demonstrated Multi Drug Resistance against different antibiotics with Extended-spectrum β-lactamase (ESBL) activity. The most frequent causative agent of bacterial sepsis in new-born children was Klebsiella pneumoniae. An alarming level of Multi Drug Resistance (MDR) Klebsiella pneumoniae strains to the first choice antibiotic treatment was observed.

Evaluation of the Quality of the Setting up of Early Mother-Born Interactions

The maternity process that has unfolded throughout the pregnancy, undergoes a turning point that occurs most of the time during the stay in diaper: place for installation of early mother-born interactions. The objective of the study is the evaluation of the quality of the establishment of early motherborn interactions as well as the effect of maternal feeling disruption on these interactions. It is a prospective study, focused on a total of 102 maternal-New-born dyads, in the unit of maternity series, at Rabat Children’s Hospital, University Hospital of Ibn Sina. It was based on a scale and an evaluation grid: the Mother-to-Infant Bonding Scale MIBQ and an evaluation grid of early mother-child interactions. The results showed that the age of the youth who is dominated at 60% (between 21 and 30 years), and that the primiparity was at 54% and 51% healthy;the correlation analysis between MIBQ and the grid shows that there is a significant correlation of average size with the emotional stability of the mother (p = 0.014 < 0.05), the quality of the attachment of the baby as his mother at the moment breastfeeding (p = 0.011 < 0.05) and the quality of the observed family context (p = 0.017 < 0.05). The installation of the mother-child relationship therefore depends on maternal capacities to recognize her place as a mother and to recognize the needs of their child, but it also depends on the child’s ability to show signs of attachment, his feelings of discomfort and pleasure.

Transition of Depressive Symptoms and Anxiety Symptoms According to Parity and Associations of These Symptoms with Feelings for Involvement with Newborn Infants during a 6-Month Postpartum Period

Background: Depressive symptoms and anxiety symptoms during the postpartum period affect physical health and child rearing and that these effects are important social issues. Objective: The aims of this study were to clarify the differences in the transition of depressive symptoms and anxiety symptoms according to parity during a 6-month postpartum period and to clarify the differences in associations of depressive symptoms and anxiety symptoms with feelings for involvement with newborn infants in primiparous and multiparous postpartum women. Methods: The design of this study was a longitudinal investigation. This study was conducted from February 2017 to July 2018 in Japan. By using self-administered questionnaires that included questions on psychological symptoms in a standard climacteric scale and questions on feelings for involvement with newborn infants, we collected data at 3 days postpartum, 2 weeks postpartum, one month postpartum, 3 months postpartum and 6 months postpartum. Results: Responses to all of the questionnaires were obtained from 121 (52.8%) of 229 women. The score for depressive symptoms in primiparous women was significantly higher than that in multiparous women at 3 days postpartum. Depressive symptoms and anxiety symptoms showed peaks at 2 weeks postpartum in both primiparous women and multiparous women, but depressive symptoms reoccurred from 3 months postpartum to 6 months postpartum in primiparous women and anxiety symptoms reoccurred from one month to 3 months postpartum in multiparous women. Depressive symptoms and anxiety symptoms were associated with negative feelings for involvement with newborn infants and with mother’s sleeping time. Conclusion: Changes in depressive symptoms and anxiety symptoms were different in primiparous women and multiparous women during a 6-month postpartum period. In addition, depressive symptoms and anxiety symptoms were associated with negative feelings for involvement with newborn infants and with sleeping time in postpartum women.

Guardians of New-Borns

WITH 38 years of history, the Beijing Maternity Hospital gained fame as the birthplace of one-fifth of all Beijingers in the 1960s. Today, some 5,000 babies are born here each year.
