High Pressure‐Temperature Study on the Thermal Equations of State of Seifertite andCaCl2‐Type SiO2

In this study, we have determined the thermal equations of state (EoS) of CaCl2‐type SiO2 and seifertite (α‐PbO2‐type SiO2) from 55 to 147 GPa up to 3500 K using X‐ray diffraction in laser‐heated diamond anvil cells. The phase transition from stishovite to CaCl2‐type SiO2 is in good agreement with previous experimental results, whereas the transition from CaCl2‐type SiO2 to seifertite was observed to strongly rely on the starting material. For CaCl2‐type SiO2, we obtained a bulk modulus, KT0 = 245(7) GPa with a fixed KT′ = 4, V0 = 48.1(2) Å3, γ0 = 1.3(3), q = 1(fixed), and θD0 = 1100(400) K. Seifertite has a greater KT0 = 290(10) GPa (KT′ = 4 fixed) than CaCl2‐type SiO2. Other thermoelastic parameters of seifertite are V0 = 92.3(5) Å3, γ0 = 1.6(2), q = 1 (fixed), and θD0 = 1600(200) K. Using the obtained results and phase boundary in previous studies, we have found that the phase transition from stishovite to CaCl2‐type SiO2 cannot cause a noticeable change in density but can lower the bulk sound velocity (VФ) by ~10%. This phase transition in the subducted oceanic crust with 20 vol.% SiO2 was estimated to generate a ~2% discontinuity in VФ, which could be related to the observed seismic velocity anomalies at depths of 1,400–1,800 km. At the bottom of the lower mantle, CaCl2‐type SiO2 to seifertite phase transition can lead to a 0.3% jump in ρ and a 0.8% jump in VΦ considering 20 vol.% SiO2 in the subducted mid‐ocean ridge basalt, which may contribute to the formation of the D″ discontinuity above the core‐mantle boundary.
The beliefs of obese people towards obesity

©Copyright 2020 by Anatolian Journal of Family Medicine Available online at www.anatoljfm. org INTRODUCTION Obesity is the 5th leading global risk for mortality in the world after high blood pressure (responsible for 13% of deaths globally), tobacco (9%), high blood glucose (6%) and physical inactivity (6%). [1] Obesity is a multifactorial complex disease that can be prevented. [2] Obesity is a state of weight gain due to environmental factors and malnutrition and is effective in genetic factors, such as other chronic diseases. Major single genes that affect severe obesity and minor genes that affect fat distribution at early stages of obesity were shown; however, these genes can explain only a small portion of body weight variation in the population.

A Decade of a Student Affairs Preconference Program: Perceptions and Characteristics of African American Women's Summit Participants

Abstract:Research related to professional development in student affairs has found that few attendees benefit from participating in preconference programs. The African American Women's Summit (AAWS) is a preconference program created by and for African American women in student affairs and serves as a professional counterspace for this significantly underrepresented population of higher education administrators. This article presents 10 years of data (2005-2015) related to participants' perceptions of the quality and relevance of the AAWS. An in-depth demographic profile of participants is included to describe the personal, professional, and educational characteristics of the African American women student affairs professionals who participated in the study. The majority of participants were 26-30 years old, employed at the director/dean level and below, had earned master's degrees, responded positively about the value of this preconference program, and noted that the AAWS represented a safe space where they were encouraged personally and professionally. These findings suggest that preconference programs, like the AAWS, developed as professional counterspaces are especially valued by minority student affairs professionals who are employed in paraprofessional, and entry- and mid-level positions.
The experience of postpartum distress in the transition to motherhood: A study of one group of low-income mothers in South Africa

The aim of this study was to explore a group of low-income South African mothers’ experience of maternal distress during the transition to motherhood. Research on mental illness in motherhood has largely focused on investigating the aetiology, prevalence rates and implications of thereof within a positivist framework. There is a dearth of studies in South Africa that has examined the lived experiences of maternal distress despite the need for a thorough and rigorous investigation of these issues from the perspective of the individual. This is especially important in South Africa, where understanding of the lived experiences of maternal distress is the first step in conceptualizing a more efficient approach to identifying and addressing postpartum distress in the resource-restricted, overburdened South African healthcare system. The present study used data from a larger research project entitled the Women’s Mental Health Research Project (WMHRP). The sample comprised of 11 low-income mothers who can be characterized as suffering from postpartum depression (given their scores on self-report measures). The longitudinal dimensions of the study enabled narrative trajectories to be collected and strategic construction and presentation of narratives to be explored. A grounded theory approach guided this study in which data was collected from interview transcriptions that were collected during the parent study. Data analysis followed the principles outlined by the social constructionist grounded theory methodology including the constant comparative method and a sequential process of open, axial, and selective coding of the data. Throughout the duration of the study, specific processes were carried out to ensure trustworthiness of the research findings. A social constructionist epistemological analytic approach, aligned with a feminist theoretical lens was used to analyse the findings. Seven superordinate categories emerged from the interviews: the mothers, the expectations and reality of motherhood, caregiving overload, dysfunctional interpersonal relationships, mothering in poverty, the physical body and motherhood and silencing of the self. These categories demonstrate how unprepared for motherhood the women were and how their expectations were based on the dominant ideology of motherhood. Overwhelmed, fatigued, ambivalent and unable to make sense of their experiences, the women continued to suffer in silence in a context of depleting resources and the loss of their former life, wellbeing and sense of self.

Characteristics and outcomes of neonates with gastroschisis managed in a public tertiary hospital in a developing country

Background . High survival rates in neonates with gastroschisis are reported in developed countries. Few studies have reported on prevalence and outcomes of neonates with gastroschisis from developing countries. Objectives . To determine prevalence, characteristics and mortality rates in neonates with gastroschisis managed in a public tertiary hospital in South Africa (SA). Methods . Hospital records of neonates with gastroschisis managed at Chris Hani Baragwanath Academic Hospital (CHBAH), Johannesburg, SA from 2009 to 2016 were reviewed retrospectively for maternal and infant characteristics, management and outcome at hospital discharge. Results . A total of 97 neonates were admitted with gastroschisis, of whom 36 were born at CHBAH which had 167 822 live births over the 8-year period (prevalence of 2.1/10 000 live births); the remaining patients were referrals. Over two-thirds of patients were born to primigravida women and were of low birthweight. Complex gastroschisis was found in 36.3% of cases, with the majority (75%) requiring staged reduction. Mortality rate was 57%, with sepsis the most common cause. Factors associated with mortality were low birthweight (odds ratio (OR) 0.19; 95% confidence interval (CI) 0.04 - 0.80), stage reduction with delayed closure (OR 3.92; 95% CI 1.05 - 14.59), place of birth (OR 4.8; 95% CI 1.44 -16.05) and complex gastroschisis (OR 0.08; 95% CI 0.02 - 0.35). Conclusion . The mortality rate observed in this study was higher than that reported in developed countries. Antenatal diagnosis of this defect and adequate staff training at peripheral hospitals on the initial care and prevention of healthcare-associated infections could improve the outcomes of neonates with gastroschisis in developing countries.
Data-Driven Recommendations for Promoting Collaboration Among School Security Personnel and School Social Workers in the United States

In response to recent incidents of school violence in the United States over the last two decades, there has been a nationwide increase in the use of school security personnel in today’s schools. Concurrently, school social work practice continues to grow as a subspecialty of social work that provides crucial services to youth in school. Despite this increase in demand across both fields of practice, and an overlap in professional interests, current research suggests that we know little about how school social workers interact with and perceive school security personnel within their schools, and ultimately how such interaction and collaboration among professionals might influence school safety. This study aims to address this gap in the literature by exploring survey responses from a nation-wide sample of school social workers who report working in schools with different types of security personnel (n = 151). Findings suggest that increased interaction and positive perceptions of school security personnel are positively associated with perceived overall safety in school. Additionally, qualitative responses suggest a considerable percentage of school social workers feel that school security personnel might benefit from additional training and increased accessibility and collaboration. The purpose of this paper is to provide timely implications for school policing using the perspective of school social workers with the goal of promoting safety and collaboration in schools.
Stretching Exercises to Prevent Work-related Musculoskeletal Disorders - A Review Article

Lower back, neck and shoulder pain, which affects the lumbar spine, are the most commonly reported Musculoskeletal Disorders (MSDs). Approximately 80 percent of the general population is affected by these disorders at a certain point during their lifetime, with some estimates being as high as 84 percent. The most commonly used approach for the treatment of MSDs is exercise therapy. Stretching provides several benefits for people at work, and may help improve morale and team cohesiveness. Another benefit of stretching is that participants may increase their range of motion compared to their counterparts who do not participate in stretching programs. Objective: The aim of this study is to synthesize the recent literature on workplace stretching exercise programs and their effects on reducing work-related MSDs in different occupational groups. Method: Specific keywords were identified and used in a systematic search to guide the discovery of relevant studies and data. Electronic databases including PubMed, ScienceDirect, and Google Scholar, were searched for the following combination of keywords: workplace, stretching, exercises, injury, work, prevention, safety, occupation, and ergonomics. Studies that do not focus on the benefits of stretching exercise were excluded simply because the present study examines prevention of work-related musculoskeletal disorders through stretching exercises. Results: Whilst majority of the literature examined in this study may not completely explain that stretching at the office will prevent work-related musculoskeletal accidental injuries, some studies have shown that performing stretching exercises can lead to reducing discomfort/pain and raising range of motion (ROM). Conclusion: Majority of the literature reviewed in this study might not fully explain that stretching at work prevents work-related musculoskeletal injuries. Some studies have shown that performing stretching exercises can contribute to reducing discomfort/pain and increasing range of motion (ROM). Particularly, construction workers who participated in stretching exercise programs reported significant positive effects including reduction in pains/disability, increase in muscle flexibility and endurance. These exercises are recommended to be performed during breaks throughout, depending on the type of occupation. All the exercises suggested could be performed at the workstation, and only require a few seconds to perform.
Vitamin B12: Could It Be a Promising Immunotherapy?

Vitamin B12 is a water-soluble vitamin and an important micronutrient with critical role in DNA, protein, and lipid synthesis. It is responsible for one-carbon metabolism and cell division of nervous and hematopoietic cells. Among its various functions, the role as immunomodulator in cellular immunity, especially in elevating the number of CD8+ cells and NK cells, attracts scientific interest. Many alternative anticancer and anti-inflam - matory treatments involve the use of B12 together with other vitamins and nutrients, but still the scientific information is too obscure and insufficient. Controversial data link tumorigenesis with either increased or decreased B12 blood levels in different types of cancer. Dietary intake and additional supplement with the vitamin do not protect against cancer risk, but the dominant opinion is to integrate B12 as part of rational and healthy nutrition to ensure proper function of the immune system. This chapter will review in brief the most important facts for vitamin B12 functions and properties. We will try also to present in concise way the human immune system and the exact role of B12 in immune activity with emphasis on the questionable participation of vitamin B12 in the process of carcinogenesis and its significance parasitism; bacterial overgrowth; medicament (antiepileptic agents, proton diabetes mellitus; renal insufficiency; smoking; and alcohol abuse.
Neurourology and Urodynamics

Correspondence Joceara Neves dos Reis, Menino Jesus Children's Hospital, Department Pediatric Urology, Rua dos Ingleses, 258, São Paulo 01329‐000, Brazil. Email: jofisio@gmail.com Abstract Aims: Evaluate the efficacy of biofeedback and parassacral electric nerve stimulation (TENS) for the treatment of children with lower urinary tract (LUT) dysfunction. Methods: A prospective, randomized study was approved by our Hospital Ethics Committee. We enrolled 64 children, 43 girls and 21 boys, average age of 9.39 years. The initial evaluation consisted of history, physical examination, urine analyses, voiding diary, uroflow, and ultrasound. Dysfunction voiding symptom score (DVSS) questionnaires were applied pre‐ and post‐treatment. The children were divided into two treatment groups independent of the predominant type of voiding dysfunction (dysfunctional or overactive bladder): biofeedback group and TENS group. The criteria for assessing the effectiveness of the techniques was the resolution of daytime and nighttime symptoms including urinary leakage, improvements in voiding diary, DVSS, and changes in uroflow. After 6 months, the children were reassessed with the same work‐up of baseline. Results: Regarding daytime symptoms, results for complete response were similar between the two groups (P= 0.483); 54.9% of children treated by the biofeedback group and 60.6% in the TENS group. The same have been observed in the nighttime incontinence with complete resolutions in 29.6% and 25%, respectively (P= 0.461). Analyzing the voiding diary, uroflow and DVSS questionnaires both groups had significant improvement (P= 0.001) after treatment. The biofeedback group required fewer sessions than TENS group, 10.9 and 18.1, respectively (P< 0,001). Conclusions: Both biofeedback and the TENS are equally effective for treating non‐neurogenic voiding dysfunction. Biofeedback seems to require a lower number of sessions to obtain similar results of the TENS.
Wideband Ultrasonic Acoustic Underwater Channels: Measurements and Characterization

In this work we present the results of a measurement campaign carried out in the Mediterranean sea aimed at characterizing the underwater acoustic channel in a wideband at ultrasonic frequencies centered at 80 kHz with a width of 96 kHz, covering two octaves from 32 to 128 kHz. So far, these type of wideband measurements are not found in the literature. Periodic orthogonal frequency division multiplexing (OFMD) sounding signals using Zadoff-Chu sequences have been specially designed for this purpose. The collected data has been post-processed to estimate the time-variant impulse and frequency responses and relevant parameters for system design like the time coherence, bandwidth coherence, delay spread and Doppler bandwidth. The statistical behavior of the channel gain random fluctuation has also been analyzed. This information has been extracted for both the global channel and each path separately. The wide bandwidth of the measurements have allowed the characterization of the channel in a scarcely explored ultrasonic band with an accuracy that is far beyond what is reported in previous works.

Drivers of Customer Satisfaction in a Business-to-Business Market: A Survey within the South African Stainless Steel Industry

The vast number of competitors and the similarity of products on offer in the South African stainless steel stockist and distributor market force organisations to find alternative means of competing effectively. Customer satisfaction might be one such an example. Whilst research has confirmed the positive outcomes of customer satisfaction, much less is known about the antecedents (drivers) that should act as the foundation of attempts to maximise satisfaction, particularly in a developing country. This study confirms five satisfaction drivers, reports the gap scores between importance and satisfaction ratings by the account clients of a major South African stainless steel stockist and distributor, and shows the relationship between these drivers and overall satisfaction. The analysis of 320 useable survey questionnaires shows a moderate to strong positive relationship with overall satisfaction for four of the five drivers. Reliability is the most important driver and product quality received the highest average satisfaction rating. Drivers with the largest significant gap scores include reliability, service quality and commercial aspects. Management should focus on the important drivers—those with the highest negative gap scores between satisfaction and importance, and those showing a significant relationship with overall satisfaction.
Structural Transitions in MgSiO3 Glasses and Melts at the Core‐Mantle Boundary Observed via Inelastic X‐ray Scattering

The structural adaptation in MgSiO3 melts under compression up to 130 GPa is the key to revealing the origins of the pronounced negative buoyancy of the melts at the core‐mantle boundary (CMB). A full understanding of the melt densification requires study of the pressure‐induced changes in the bonding configuration around oxygen at the CMB, which has proven to be difficult to measure. Here, the experimental breakthrough in O K‐edge inelastic X‐ray scattering enables collection of the spectra of MgSiO3 glasses up to ~130 GPa, along with ab initio molecular dynamics simulations, revealing the electronic bonding transitions around heavily compressed oxygen. The spectral results indicate the emergence of denser network structures around oxygen, stemming from contractions in the Mg‐O and O‐O distances associated with flexible topological and short‐range rearrangements around Si. The results unveil the electronic structure and thus the nature of densification in dense partial melts at the CMB.
