Abstract
Transportation, handling, and corrosion damage to the threads of oilfield tubulars cost the industry millions of dollars each year. This problem has intensified with the increased use of proprietary connections which represent a significant percentage of the total tubular cost. The thread protector is the primary means of protecting the threads from impact and corrosion damage. Exxon Production Research Company has designed a test program and built a test facility to evaluate the performance of oilfield thread protectors. A wide variety of thread protectors were evaluated which included metal, plastic, and composite (metal-elastomer) designs. This paper discusses this testing and outlines a guide for the selection of oilfield thread protectors for various service conditions.

Abstract
Carboxymethyl sago starch (CMSS) hydrogel was prepared by dissolving CMSS in HCl solution under vigorous stirring to form gel. The parameter studied were the effect of the percentage of CMSS, concentration of the acid solution, reaction time and reaction temperature to identify the optimum condition of preparation of CMSS hydrogel. 60% of CMSS in 2.0M acid solution for 12 hours reaction time at room temperature were the optimum conditions for CMSS hydrogel. The hydrogel was characterized by using Fourier Transform Infrared (FT-IR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). FTIR spectrum of CMSS shows an additional absorption band at 1597 cm-1 indicating the substitution of CH2COO-Na+ group on the starch molecular chain during carboxymethylation, while the spectrum of CMSS hydrogel shows an additional sharp absorption band at 1723 cm-1 indicating that the Na in CMSS being exchanged to H from hydrochloric acid solution. SEM image of CMSS hydrogel shows pores in structure and connected to each other to form networks. TGA curve shows that the maximum rate of thermal decomposition of CMSS hydrogel is higher than CMSS at 330.22 ºC with 60.22% major weight loss. This could be due to the presence of the cross-linkages in the CMSS hydrogel. CMSS hydrogel gives high swelling degree in PBS solution at pH 7 and low swelling degree in acidic medium.

Abstract
Introduction

There is an urgent need for efficacious interventions to combat the global mental health crisis, and mental health promotion and primary preventive approaches are paramount.

Objective

This study examined whether an online multimodal intervention that incorporates evidence-based strategies from the disciplines of Lifestyle Medicine and Positive Psychology improved measures of mental health and emotional wellness.

Methods

425 adults (68.8% females, aged 46.5 ± 15.6) from Australia and New Zealand were randomised to an intervention or control group. The intervention group participated in a ten-week online multimodal intervention. Measures of mental health and emotional wellness were taken at baseline (Week 1), post-intervention (Week 12), and 12 weeks post-intervention (Week 24). The control group completed the same assessments.

Results

The intervention group experienced significant improvements from Week 1 to 12 in: mental health (10%, p<0.001, d=0.50) and vitality (22%, p<0.001, d=0.54) subscales of the Short Form Survey (SF-36); depression (-42%, p<0.001, d=0.48), anxiety (-38%, p<0.001, d=0.39) and stress (-31%, p<0.001, d=0.52) subscales of the Depression, Anxiety and Stress Scale (DASS-21); and life satisfaction (8%, p<0.001, d=0.48) as measured by the Satisfaction With Life Scale (SWLS).The control group experienced significant improvements only in the mental health (3%, p=0.028, d=0.16) subscale of the SF-36, and the stress subscale (-9%, p=0.038, d=0.15) of the DASS-21. The changes in the intervention group were significantly greater (p<0.001) than the control group for all measures. Improvements in the outcome measures were generally sustained for the intervention group at 12 weeks post-intervention.

Conclusion

The online multimodal intervention improved measures of mental health and emotional wellness suggesting that such interventions may be useful for mental health promotion and prevention.

Abstract
Background: Mechanical ventilation joint PS replacement therapy is an effective method in treatment of NRDS recognized, PS treatment of children with early can improve the oxygenation by increasing gas exchange area, but before FiO 2 to reduce the application of PS can cause local and/or systemic hemodynamic changes, making the use of PS has some potential problems, such as increasing the incidence of the IVH, PH, PDA and so on. SR rescue therapy can be divided into early treatment and delayed treatment, but the specific boundary point of the appropriate time period has not been clear. This paper aims to compare the efficacy differences of PS administration at different time periods and provide basis for the selection of clinical application period of PS. Methods: Case-control study . 135 children diagnosed with NRDS in neonatology department of our hospital. The patients were divided into two groups according to the use time of PS. Group A was applied within 3 hours after birth, and group B was applied 3 hours after birth. The changes of blood gas analysis parameter，mechanical ventilation time, incidence of complications, hospital stay and mortality were compared between the two groups. Results : The decrease of blood gas PaCO 2 in group A before and after treatment was more significant than that of group B (P<0.05), but the improvement of PaO 2 and OI in group B was better than that in group A (P<0.05). Although there were significant differences in birth weight between the two groups, there were no significant differences in the total duration of mechanical ventilation and mortality (P>0.05). Except PDA and BPD, there was no significant difference in the incidence of common complications between the two groups. Conclusion: PS treatment within 3 hours after birth can better improve ventilation, reduce the incidence of PDA. It can also help to reduce the death rate of high-risk children and the total duration of mechanical ventilation.

Abstract
BackgroundsEye disease burden is essential to life quality and crucial when making universal health policy with aging of population. Gender difference is a major factor of reducing burden caused by near vision loss (NVL). The research aimed to evaluate the trends and gender inequality in global health burden of NVL by year, age, and socioeconomic status using the disability-adjusted life years (DALY) from the Global Burden of Diseases (GBD) 2017 study. MethodsThe related DALY measurements were extracted from the GBD Study 2017. Human development index (HDI) in 2017 was obtained from the Human Development Report. The difference in age-standardized DALY rates (ASR) among four subgroups classified by HDI was compared by Mann-Whitney U tests. The effect of HDI on gender difference in ASR was investigated by Pearson correlation analyses and regression analyses.ResultsGender difference has grown slightly since 1990, with ASR being 110 among males vs. 129 among females in 1990 and 108 vs. 134 in 2017. Gender inequality have existed in most WHO regions except European region. Females had higher burden of than males the same age and the inequality peaked around 50 years old, but men over 80 years old suffered greater burden. Female-minus-male difference in ASR (r = -0.428, P<0.001; standardized β = -0.428, P<0.001) and female-to-male ASR ratios (r = -0.410, P<0.001; standardized β = -0.410, P<0.001) were negatively related to HDI. ConclusionGender inequality had persisted since 1990 and grown slightly these decades. The burden was heavier in women, especially in those elderly and from less developed countries. Gender inequality caused by NVL must be taken into consideration when making health care policy, reforming universal health and education coverage.

Abstract
Background Excessive daytime sleepiness (EDS) is a common sleep abnormality among adolescents, and is reported to be associated with increased risk of morbidity and mortality. Multiple factors have been associated with EDS, especially life style. This study aimed to explore the relationships between dietary behaviors and EDS.Methods A total of 988 Iranian adolescent girls aged between 12-18 years old were recruited this cross-sectional study. A Persian translation of the Epworth Sleepiness Scale (ESS) was used to determine the presence of EDS. A pre-validated questionnaire was used for the assessment of dietary behaviors. To investigate the association between diet-related practices and the prevalence of EDS, we applied logistic regression analysis.Results The subjects who consumed a major meal three times daily had a 0.56 lower odds for EDS than the individual who consumed a single major meal (OR: 0.44; P = 0.01). Individuals with a ‘high-rate of food chewing’ were less likely to have EDS (OR: 0.55; P = 0.03). Compared with those who consumed fried or spicy foods daily, individuals who never consumed fried (OR: 1.8; P = 0.02) or spicy foods (OR: 1.71; P = 0.01) had a greater risk for EDS. In addition, there were direct associations between meal regularity and intra-meal fluid intake with EDS in an adjusted models. Neither in the crude nor in the adjusted models, were there significant associations between breakfast intake and frequency of snack consumption with EDS.Conclusions The findings of our study show the importance of diet-related practices in determining EDS. Prospective intervention studies are required to confirm these results.

The prevalence of Hookworm and associated factors among podoconiosis patients and healthy residents has not been studied.Objective to determine the prevalence of Hookworm and associated risk factors among podoconiosis patients and healthy residents.Methods A cross-sectional study was conducted at Debre Elias from January to February 2018. One hundred ninety two participants were included. Stool sample was collected for microscopy, kato-katz and formalin ether concentration technique. Logistic regressions were performed to assess association between variables. P-value < 0.05 was used as statistically significant.Result The prevalence of Hookworm among podoconiosis patients was 84.4% and 75% among control. Hookworm infection was relatively higher among podoconiosis patients 52.9%. Higher age group, illiterate and farmers more affected with high proportion of podoconiosis patients. Being a formers, no history of stool examination and no shoe wearing habit were significantly associated with hookworm infection (AOR = 4.1; 95% CI= (1.65- 10.11)), (AOR = 3.03; 95% CI= (1.11-8.25)) and (AOR= 3.9; 95% CI= (1.11-14.24) respectively.

Published: August 2019

Abstract
Background: Managing labor pain and early postpartum pain has been linked to a reduced risk for postpartum depression and pain. However, the role of labor pain and the overall birth experience in the development of postpartum depression and persistent pain still remains unclear.
Methods: The study sample (n=2217) was drawn from the Akershus Birth Cohort, which targeted all pregnant women scheduled to give birth at Akershus University Hospital in Norway between 2008-2010. Data from the hospital’s birth record as well as questionnaire data from gestational week 17 of pregnancy and eight weeks postpartum were used. An additional questionnaire about labor pain and birth experience was answered by 1 244 women within 48 hours after delivery. The Edinburgh Postnatal Depression Scale was used to measure postpartum depression, a single question was used to measure persistent pain eight weeks postpartum, while pain and birth experience were measured by numeric rating scales within 48 hours after delivery.
Results: The results showed that neither labor pain nor birth experience were associated with persistent pain eight weeks postpartum, whereas pain before pregnancy (OR 3.70; 95% CI 2.71-5.04) and a history of depression (OR 2.31; 95% CI 1.85-2.88) were statistically significant predictors of persistent pain. A negative birth experience was significantly (OR 1.16; 95% CI 1.04-1.29) associated with postpartum depression, whereas labor pain intensity was not. Again, a history of depression (OR 3.95; 95% CI 2.92-5.34) and pre-pregnancy pain (OR 2.03; 95% CI 1.37-3.01) were important predictors of postpartum depression eight weeks after delivery.
Discussion: Whilst the relationship between labor pain intensity and postpartum pain and depression remain unclear, our results do imply the need to screen for previous depression and chronic pain conditions in pregnant women, as well as consider preventive measures in those who screen positive.

Published: August 2019

The chemical and stable isotopic compositions (δ34SSO4 and δ18OSO4) of Xijiang River water in southwest China, were measured to determine the extent of rock weathering and associated CO2 consumption rates, and to assess the contamination sources of river water. The SO42− concentration in the river water was in the range of 0.05 to 0.96 mmol L−1 (mean value = 0.32 mmol L−1) and was characterized by δ34SSO4 values ranging from −9.1 to 5.1‰ (mean value = −2.1‰) and δ18OSO4 values ranging from −0.4 to 10.8‰ (mean value = 5.0‰). The δ34SSO4 and δ18OSO4 values ranged from high to low from the upper reaches to the lower reaches in all the river water samples. The results indicate that the oxidation of sulfide and anthropogenic inputs are the dominant processes affecting SO42− sources and S cycling of the Xijiang River during high‐discharge conditions, which are controlled by regional hydrological processes that are affected by natural processes and anthropogenic inputsCore Ideas
The dual isotopes (δ34SSO4 and δ18OSO4) of sulfate indicated S sources.
The weathering rates of carbonate and silicate were calculated.
The relative contributions of various sources are identified.

Redeveloping Peace in Contemporary Islam
Authors: Rochmawati Nikmah 
Published: August 2019

There has been a long debate when it comes to understanding the meaning of Islam. The proponents of Islam claim Islam as a religion of peace, while on the other hand, who are mostly Westerners, would dissent this claim by addressing jihad as a violent product of Islam. The Westerners certainly fail to grasp the spirit of peace in Islam because very often their argumentations are based on material events instead of philosophical approach. This paper is an effort to shed light the true meaning of Islam by analyzing it from its philosophical aspects. Literal interpretations are specifically used as a method to analyze texts in the Quran and the Hadith to reveal the etymological, epistemological, and ontological meanings of Islam. Additionally, Max L. Stackhouse’s normativity ethical approach is utilized as a framework to analyze the meaning of Islam from its textual and contextual doctrines. Three prominent concepts (true-false, good-bad, and appropriate-inappropriate) of normativity ethical approach are used in particular to reveal the spirit of peace towards the meaning of Islam. The conclusion derived from the etymological and epistemological analyses is that Islam means obedience, subjugation, and submission to God as an effort to seek safety and happiness in the world and the world after. The ontological analysis shows that Islam is a religion of peace in which its two principal teachings are believing in Allah and nurturing unity and friendship among the mankind. Islam is hoped to be comprehended as a religion that is friendly and becomes <em>rahmatan lil alamin</em>. The analysis using Stackhouse’s normativity ethical approach focuses on the term jihad which is mean restraining from wars. When it comes to wars, jihad must be done with the spirit to erase oppression, enforce the freedom of belief, and disseminate the message of peace. Eventually, jihad itself is the manifestation of peace which is truly the spirit of Islam

Published: August 2019

Background:A functional polymorphism (5-HTTLPR, rs4795541) in the serotonin transporter (SLC6A4) gene has been shown as an important candidate for several psychiatric and behavioral traits.Objective:The objective of this study was to examine the possible interaction of this polymorphism with physical neglect in childhood on the presentation of anxiety traits and hazardous alcohol consumption in young Colombian subjects.Methods:272 young adults (mean age: 21.3 years) were evaluated with the Childhood Trauma Questionnaire, the Zung Self-rating Anxiety Scale, the Big Five Inventory, the Cohen’s Perceived Stress Scale, the Alcohol, Smoking, Substance Involvement Screening Test and the Alcohol Use Disorders Identification Test. Genotyping for the 5-HTTLPR polymorphism was carried out using conventional PCR. A linear regression model, corrected by age and gender, was used.Results:We found that individuals with the L/L genotype showed higher scores on physical neglect (p=0.0047), anxiety symptoms (p=0.028), neuroticism (p=0.019) and perceived stress (p=0.035). L/L genotype was a risk factor for hazardous alcohol use in young adults (OR=3.06,p=0.0003). No GxE interactions were observed in our data.Conclusion:Our results provide novel evidence for the role of a functional polymorphism in theSLC6A4gene on the relationship of childhood trauma, anxiety-related traits and risky consumption of alcohol.

Este artigo é dedicado a « Narcisse parle », uma das numerosas aparições do mito de Narciso na poesia de Paul Valéry (1871-1945). Após apresentar sucintamente a gênese, a métrica, o percurso, a organização e a enunciação do poema, abordamos as referências espaciais e temporais. Finalmente, tratamos dos personagens a fim de mostrar os laços entre o herói e as figuras que o cercam, especialmente as ninfas e o reflexo que ele ama. A análise desses aspectos permite-nos compreender a arquitetura do poema, explicitando, por exemplo, a natureza do sofrimento do protagonista e caracterizando sua paixão.
