AbstractMental health problems are common in childhood and tend to be more frequent in populations at risk of poverty or social exclusion (AROPE). The family environment can play a role in reducing the impact of economic hardship on these problems. The aim of this study was to assess the effect of multidimensional poverty on the mental health of children aged 7–11 years and the role of the family environment in two areas of Spain. Participants were 395 and 382 children aged 7 and 11 from Gipuzkoa and Valencia, respectively. Internalizing and externalizing problem scales of the child behaviour checklist (CBCL) were used. AROPE indicators were obtained by questionnaire, and three dimensions of the family context (Organization of the Physical Environment and Social Context, Parental Stress and Conflict, and Parental Profile Fostering Development) were measured through subscales 3, 4 and 5 of the Haezi-Etxadi family assessment scale (7–11) (HEFAS 7–11), respectively. Data were analysed using negative binomial regression and Structural Equation Modelling. AROPE prevalence was 7.1 and 34.5% in Gipuzkoa and Valencia, respectively. In both cohorts, there was a significant increase in internalizing and externalizing problems among participants with a higher AROPE score. However, AROPE did not affect internalizing problems in children from families living in a better physical environment and with social support (Subscale 3). The AROPE effect was jointly mediated by subscales 4 and 5 in 42 and 62% of internalizing and externalizing problems, respectively. Preventing economic inequities by economic compensation policies, improving the neighbourhood and immediate environment around the school, and promoting positive parenting programmes can improve mental health in childhood.

Authors: Olsson A. , Kiwanuka O. , Sandblom G. , Stackelberg O. 
Published: July 2021

Abstract
Introduction
Over the last decade rectus diastasis has gained attention as a condition that may benefit from surgery. Numerous surgical techniques have been presented but scientifically proper studies reporting functional outcome are few and evidence is incomplete. The aim of this up-to-date review is to analyse the outcomes of rectus diastasis repair in recently published papers, focusing on functional changes following surgery.

Method
A comprehensive search in PubMed and Web of Science was performed. Suitable papers were selected using titles and abstracts with terms suggesting surgical treatment of rectus diastasis. All abstracts were scrutinised, and irrelevant studies excluded in four stages. Reports providing original data, including outcome assessment following surgery, were included.

Result
Ten papers with a total of 780 patients were found to fulfil the search criteria. Study design, surgical procedure, follow-up time, functional outcome and assessment instruments were compiled. All included studies reported improvements in a variety of functional aspects regardless of surgical method. The outcomes assessed include core stability, back pain, abdominal pain, posture, urinary incontinence, abdominal muscle strength and quality of life.

Conclusion
The results of this review show that surgical repair of rectus diastasis is a safe and effective treatment that improves functional disability. However, the absence of standardized instruments for assessing outcome makes it impossible to compare studies. Since indications for surgery are relative and related to core function, valid instruments for assessing indication and outcome are needed to ensure benefit of the procedure.

Published: July 2021

AbstractA radial integral boundary element method (BEM) is used to simulate the phase change problem with a mushy zone in this paper. Three phases, including the solid phase, the liquid phase, and the mushy zone, are considered in the phase change problem. First, according to the continuity conditions of temperature and its gradient on the liquid-mushy interface, the mushy zone and the liquid phase in the simulation can be considered as a whole part, namely, the non-solid phase, and the change of latent heat is approximated by heat source which is dependent on temperature. Then, the precise integration BEM is used to obtain the differential equations in the solid phase zone and the non-solid phase zone, respectively. Moreover, an iterative predictor-corrector precise integration method (PIM) is needed to solve the differential equations and obtain the temperature field and the heat flux on the boundary. According to an energy balance equation and the velocity of the interface between the solid phase and the mushy zone, the front-tracking method is used to track the move of the interface. The interface between the liquid phase and the mushy zone is obtained by interpolation of the temperature field. Finally, four numerical examples are provided to assess the performance of the proposed numerical method.

AbstractBackground People with Parkinson’s are at higher risk of healthcare and pharmaceutical care issues. Objective To determine the healthcare challenges, pharmaceutical care needs, and perceived need of a pharmacist-run clinic by people with Parkinson’s and their caregivers. Setting Malaysian Parkinson’s Disease Association. Method A focus group discussion adopting a descriptive qualitative approach was conducted involving people with Parkinson’s and their caregivers. A semi-structured interview guide was used to determine the challenges they faced with their medications and healthcare system, their pharmaceutical care needs, and their views on a pharmacist-run clinic. Data was thematically analysed. Main outcome measure: Healthcare challenges faced by people with Parkinson’s and caregivers along with their pharmaceutical care needs and perceived need of a pharmacist-run clinic. Results Nine people with Parkinson’s and four caregivers participated. Six themes were developed: (1) “It’s very personalised”: the need for self-experimentation, (2) “Managing it is quite difficult”: challenges with medication, (3) “The doctor has no time for you”: challenges with healthcare providers, (4) “Nobody can do it except me”: challenges faced by caregivers, (5) “It becomes a burden”: impact on quality of life, and (6) “Lack of consistency could be counterproductive”: views on pharmacist-run clinic. Conclusion The provision of pharmaceutical care services by pharmacists could help overcome issues people with Parkinson’s face, however there is a need for them to first see pharmacists in their expanded roles and change their limited perception of pharmacists. This can be achieved through integration of pharmacists within multidisciplinary teams in specialist clinics which they frequent.
Modelling height-diameter relationships in complex tropical rain forest ecosystems using deep learning algorithm

Published: July 2021

AbstractModelling tree height-diameter relationships in complex tropical rain forest ecosystems remains a challenge because of characteristics of multi-species, multi-layers, and indeterminate age composition. Effective modelling of such complex systems required innovative techniques to improve prediction of tree heights for use for aboveground biomass estimations. Therefore, in this study, deep learning algorithm (DLA) models based on artificial intelligence were trained for predicting tree heights in a tropical rain forest of Nigeria. The data consisted of 1736 individual trees representing 116 species, and measured from 52 0.25 ha sample plots. A K-means clustering was used to classify the species into three groups based on height-diameter ratios. The DLA models were trained for each species-group in which diameter at beast height, quadratic mean diameter and number of trees per ha were used as input variables. Predictions by the DLA models were compared with those developed by nonlinear least squares (NLS) and nonlinear mixed-effects (NLME) using different evaluation statistics and equivalence test. In addition, the predicted heights by the models were used to estimate aboveground biomass. The results showed that the DLA models with 100 neurons in 6 hidden layers, 100 neurons in 9 hidden layers and 100 neurons in 7 hidden layers for groups 1, 2, and 3, respectively, outperformed the NLS and NLME models. The root mean square error for the DLA models ranged from 1.939 to 3.887 m. The results also showed that using height predicted by the DLA models for aboveground biomass estimation brought about more than 30% reduction in error relative to NLS and NLME. Consequently, minimal errors were created in aboveground biomass estimation compared to those of the classical methods.

AbstractThis study aimed to determine the quality of drinking water supplied in different types of food stalls in Jashore Municipality, Bangladesh. A total of 35 water samples were collected from different tea stalls, street side fast food stalls, normal restaurants and well-furnished restaurants. The water quality was evaluated by determining the distinct physical, chemical and biological parameters. The results revealed that the water used in the food stalls and restaurants for drinking purpose was in desired quality in terms of turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), sulfate (SO42−), phosphate (PO43−), chloride (Cl−), sodium (Na) and potassium (K) concentrations. The values were within the permissible limit proposed by the Bangladesh Bureau of Statistics and the World Health Organization. Concentrations of calcium (Ca) and magnesium (Mg) found in several samples were higher than the World Health Organization standard. Iron (Fe) concentrations were higher than the permissible limit of the World Health Organization. Only 46% exceeded the permissible limit of Bangladesh Bureau Statistics. The threatening result was that the samples were contaminated by fecal coliform, indicating that the people of Jashore Municipality may have a greater chance of being affected by pathogenic bacteria. The drinking water provided in the street side fast food stalls was biologically contaminated. The findings demonstrate that the drinking water used in food stalls and restaurants of Jashore Municipality did not meet up the potable drinking water quality standards and therefore was detrimental to public health.

Published: July 2021

AbstractDelivering efficient and cost-effective drilled and excavated holes require effective prediction of instability along the hole profile. Most drilled and excavated hole stability analyses in the literature are performed for a given zone without considering the influence of depth. This study focused on determining the influence of depth on induced geo-mechanical, chemical, and thermal stresses and strains in drilled or excavated holes. To this end, a new porochemothermoelastic model was developed based on extended poroelastic theory, and the developed model was employed in determining induced strains and stresses for an oil and gas well case study, using data from the literature. The study delineated the different significance levels of geo-thermal-, chemical-, and thermal-induced strains and stresses as depth increased. From the results obtained, it was clear that at shallow depths, chemically induced strains and stress were the most significant formation perturbations responsible for instability of drilled and excavated holes. On the other hand, at deeper depths, geo-mechanical-induced strains and stress were the most predominant. Comparatively, thermally induced strains and stresses were found to be the least significant formation perturbations responsible for instability of drilled and excavated holes. For this case study, the results indicated that chemical strains and stresses were more prominent at depths below 170 m, accounting for more than 50% of the total stresses and strains. At 170 m, both chemical and geo-mechanical stress and strain had equal contributions to the overall stress and strain. However, as depth increased, the percentage contribution of the geo-mechanical component increased and accounted for about 80% of the total strains and stresses at 1000 m, which increased to 98.48% at depths of 6000 m and beyond. The findings of this study will provide guide for future studies on the application of extended poroelasticity theory in solving instability problems of drilled and excavated holes.
A learning-from-data approach with soft clustering and path relinking to the history-matching problem

Published: July 2021

AbstractHistory matching is an important reservoir engineering process whereby the values of uncertain attributes of a reservoir model are changed to find models that have a better chance of reproducing the performance of an actual reservoir. As a typical inverse and ill-posed problem, different combinations of reservoir uncertain attributes lead to equally well-matched models and the success of a history-matching approach is usually measured in terms of its ability to efficiently find multiple history-matched models inside the search space defined by the parameterization of the problem (multiple-matched models have a higher chance of better representing the reservoir performance forecast). While studies on history-matching approaches have produced remarkable progress over the last two decades, given the uniqueness of each reservoir’s history-matching problem, no strategy is proven effective for all cases, and finding alternative, efficient, and effective history-matching methodologies is still a research challenge. In this work, we introduce a learning-from-data approach with path relinking and soft clustering to the history-matching problem. The proposed algorithm is designed to learn the patterns of input attributes that are associated with good matching quality from the set of available solutions, and has two stages that handle different types of reservoir uncertain attributes. In each stage, the algorithm evaluates the data of all-available solutions continuously and, based on the acquired information, dynamically decides what needs to be changed, where the changes shall take place, and how such changes will occur in order to generate new (and hopefully better) solutions. We validate our approach using the UNISIM-I-H benchmark, a complex synthetic case constructed with real data from the Namorado Field, Campos Basin, Brazil. Experimental results indicate the potential of the proposed approach in finding models with significantly better history-matching quality. Considering a global misfit quality metric, the final best solutions found by our approach are up to 77% better than the corresponding initial best solutions in the datasets used in the experiments. Moreover, compared with previous work for the same benchmark, the proposed learning-from-data approach is competitive regarding the quality of solutions found and, above all, it offers a significant reduction (up to 30 × less) in the number of simulations.

Published: July 2021

AbstractIn the actual exploitation process of coalbed methane (CBM), as the fluid in the wellbore continues to circulate, the surrounding rock of the CBM well will continuously exchange heat with the fluid in the wellbore, resulting in continuous changes in the temperature of the surrounding rock itself. Linfen, Shanxi is the main exploitation area for CBM in China. This paper aims further to improve the exploitation efficiency of CBM in this area and conducts experimental research on the change characteristics of coal-rock mechanical properties under varying temperature conditions. The experimental results show that under constant pressure conditions, the higher the temperature, the lower the stress value when the coal-rock breaks. In the process of reaching peak strength, the higher the temperature, the higher the proportion of coal-rock plastic deformation in its entire deformation stage. The compressive strength, elastic modulus, and main crack length of coal-rock will decrease with temperature. The Poisson's ratio and primary fracture angle will increase with the increase of experimental temperature.
Geophysical and hydrocarbon prospect evaluation of Nukhul Formation at Rabeh East oil field, Southern Gulf of Suez Basin, Egypt
Authors: Sarhan Mohammad Abdelfattah 
Published: July 2021

AbstractNukhul Formation is one of the primary oil reservoirs in the Gulf of Suez Basin. Rabeh East is an oil producer field located at the southern border of the Gulf of Suez. The present work deals with the geophysical investigation of Nukhul Formation in Rabeh East field using seismic lines and well log data of four wells, namely RE-8, RE-22, RE-25 and Nageh-1. The interpreted seismic profiles display that the RE-8 Well is the only well drilled within the up-thrown side of a significant horst fault block bounded by two normal faults. However, the other wells penetrated the downthrown side. The qualitative interpretation of the well logging data for RE-8 Well delineated two intervals have good petrophysical parameters and ability to store and produce oil. These zones locate between depths 5411.5 and 5424 ft (zone I) and between 5451 and 5459.5 ft (zone II). The calculated petrophysical parameters for zone I display water saturation (22–44%), shale volume (10–23%), total porosity (18–23%), effective porosity (12–20%) and bulk volume of water (0.04–0.06). Zone II exhibits water saturation (13–45%), shale volume (10–30%), total porosity (18–24%), effective porosity (11–20%) and bulk volume of water (0.03–0.05). This analysis reflects excellent petrophysical characteristics for the sandstones of Nukhul Formation in Rabeh East oil field for producing oil if the wells drilled in a suitable structural closure.

Published: July 2021

ZusammenfassungIn der Studie wird untersucht, inwiefern sich die kokonstruktive Lehrpersonen-Kooperation in Schulen, die ihren Unterricht bottom-up in Richtung einer stärkeren Personalisierung des Lernens weiterentwickeln, verändert. Die Daten wurden im Zeitraum von drei Schuljahren in 43 Schulen mittels Fragebögen (t1, t3) und in elf dieser Schulen zusätzlich durch Leitfadeninterviews (t1, t2, t3) erhoben. Wie die statistischen und inhaltsanalytischen Auswertungen übereinstimmend zeigen, kooperieren die Lehrpersonen bei der Unterrichtsentwicklung rege, mit unterschiedlichen Partner/innen und kokonstruktiv. Die kokonstruktive Kooperation nimmt im Untersuchungszeitraum bei der Planung, Entwicklung und Auswertung von Unterricht für personalisiertes Lernen sowie im Umgang mit unterrichtlichen und schulischen Herausforderungen deutlich zu. Es entstehen Kooperationskulturen, die nicht nur die Unterrichtsentwicklung voranbringen, sondern auch bei beruflichen und persönlichen Problemen starken Rückhalt geben. Die Ergebnisse zeigen, dass unterrichtsbezogene Innovationen, die von den einzelnen Schulen ausgehen und gemeinsam bejahte Ziele verfolgen, die kokonstruktive Kooperation zwischen Lehrpersonen fördern und zum pädagogischen Handeln als kollegiale Lerngemeinschaften beitragen.

Published: July 2021

Abstract
Background
In patients with obesity and end-stage kidney disease, implantation of the peritoneal dialysis (PD) catheter may be complicated by increased abdominal circumference or skin folds. Relocation of the implantation site to the upper abdomen could solve this problem. However, this would require an extended catheter.

Methods
We developed an extended PD catheter based on a swan neck Missouri PD catheter with the help of two adaptors and a straight intraperitoneal extension segment. The extended catheter was assembled intraoperatively, and its length was adjusted individually to ensure correct positioning. After the operation, PD was commenced and handled as usual.

Results
In the period from 2011 to 2021, we implanted 31 extended PD catheters in 29 patients (38% men) with end-stage renal failure and obesity. Median age was 53 (range 28–77) years and body mass index was 35.5 (range 26.4–46.9) kg/m2. The postoperative course was unremarkable except for seroma formation in one patient and dialysate leakage in another. Continuous ambulatory peritoneal dialysis (CAPD) was initiated in 20 and APD in 9 patients. The achieved median Kt/V was 2.10 (range 1.50–3.10). During the follow-up period lasting up to 51 months, there was one case of intraperitoneal catheter disconnection due to an avoidable handling error. The peritonitis rate was 1:40 months. The 1- and 2-year catheter survival was 92% and 67%, respectively, and paralleled patient survival.

Conclusions
When using a PD catheter with an intraperitoneal extension, PD catheter implantation can be relocated to the upper abdomen in patients with obesity, thus providing optimal position and easy surgical access.
