Contemporary Western Scholarship on Islam: An Appraisal of Selected ‘Introductory’ Reference Works on Islamic History
Authors: Parray Tauseef Ahmad 
Published: January 2022

Writing on Islamand things Islamic has a long history in the West, but has seen a growth in 20thcentury and an unprecedented surgeafter the events of 9/11 (2001)—both because of Islam’s ‘global’ spread and ‘growing global impact’ as well as its diverse interpretations and explanations. Among this plethora of literature, a major portion is devoted to the Islamic historyand its inter-related aspects, in the form of ‘introductory’ reference books.These are primarily targeted for (under) graduate student community as well as for the general people interested in knowing about the faith and beliefs of 1.6 billion Muslims, living globally. This study, in this context, attempts to present an evaluation and brief content-analysis of four (4) latest works by the Western academics (mostly ‘Islamicists’) on Islamic history, published in between 2009 and 2016 (and referring to their latest editions as well). Theoretical in nature, following both descriptive and comparative methodological approaches, this study attempts to (i) get clues of the recent trends, tendencies and tenors in the English (predominantly American) scholarship on Islamic history; and (ii) identify the main topics, themes and issues covered under the broader rubric ofIslamic history/ civilization in these works. The study agrues that such mins of appraisal and evaluation helps in understanding the main themes/ topics discussed under the broader rubric ofIslamic historyas well as helps in knowing and understanding the diverse scholarly approaches adopted in studying different aspects of Islamic history—from classical to contemporary eras.
QUELQUES RÉFLEXIONS SUR LA POÉSIE FRANÇAISE DE LA SECONDE GUERRE MONDIALE
Authors: Popović Diana 
Published: January 2022

Pendant la Seconde Guerre mondiale en France certains poètes estiment qu’ils ont un rôle social considérable et se font les porte-parole des opprimés. Ils s’engagent dans la lutte corps à corps mais aussi la plume à la main, tout en élevant leur voix pour proclamer leur foi en la liberté et pour montrer que leurs vers patriotiques peuvent devenir une arme virulente contre l’occupation nazie et les souffrances du peuple. Les poètes deviennent donc messagers de paix et d’espoir et les combattants apprennent leurs poèmes par cœur ou on les diffuse légalement ou clandestinement. Mais il est possible de voir les choses sous un autre angle : il existait un certain nombre de poètes qui refusaient tout engagement littéraire, comme c’était le cas des anciens surréalistes, de même, il y avait des poètes qui s’engageaient du côté de la Collaboration, ou ceux qui refusaient de publier ou ne pouvaient même pas le faire sous l’Occupation pour des raisons diverses : matérielles, morales ou autres. Nous nous proposons d’aborder cette problématique, certainement très vaste et complexe, en prenant en considération les contraintes d’un article.
ŽÁNROVÁ CHARAKTERISTIKA BIBLICKEJ SÁGY V PRIESTORE SLOVENSKEJ LINGVOŠTYLISTIKY

Published: January 2022

Problematika žánrovej charakteristiky biblických textov nebola v slovenskej jazykovede doteraz komplexne spracovaná. V našom príspevku skúmame ságu Starej zmluvy ako žánrovú jednotku, ktorú možno charakterizovať na základe viacerých kritérií uplatňujúcich sa v komplexnosti a vo vzájomnej podmienenosti. Ságu charakterizujeme ako synchrónny žáner, ktorý má invariantné znaky a vlastnosti vyplývajúce z biblického textu ako špecifického náboženského komunikátu. Zameriame sa na tie vlastnosti biblickej ságy, cez ktoré nadobúda parametre jedinečnosti a odlišnosti vo vzťahu k iným biblickým textom. V práci vychádzame z doterajších teoreticko-metodologických koncepcií slovenskej štylistiky a z jazykovedných sond do problematiky biblických textov.
Childcare, work or worries? What explains the decline in parents' well-being at the beginning of the COVID-19 pandemic in Germany?
Authors: Vicari Basha , Zoch Gundula , Bächmann Ann-Christin 
Published: January 2022

Objective: We examine how care arrangements, general and altered working conditions, and worries influenced subjective well-being at the onset of the COVID-19 pandemic for working parents in Germany.
Background: Prior research suggests several reasons for declines in subjective well-being, particularly for working mothers. We employ Pearlin's (1989) stress process model to explore the role of parental childcare, altered working conditions and amplified worries of working parents in terms of increased stressors and modified resources to cope with the extraordinary situation.
Method: We use data from two starting cohorts from the National Educational Panel Study and its supplementary COVID-19 web survey from spring 2020 to examine possible heterogeneities in contextual factors for individual-level changes in the well-being of working mothers and fathers.
Results: We confirm a more pronounced decline in well-being for working mothers than fathers. Part-time work and access to emergency care reduce the gender gap in decreased well-being. Conversely, young children in the household and personal worries are associated with lower well-being for both parents. However, we cannot explain the more significant decrease in mothers’ well-being by increased childcare responsibilities or altered working conditions.
Conclusion: A greater decline in well-being indicates a particular burden among working mothers. However, it cannot be linked solely to gendered inequalities in the changes of paid and unpaid work during the first months of the pandemic.

Highlight:1. The signs and symptoms of patients with pulmonary tuberculosis and those of diabetes mellitus were similar.2. Male, aged 51-75 years old, and working in private sector are characteristics of most of the diabetic patients with pulmonary tuberculosis.Abstract:Background: Diabetes Mellitus is a type of disorder where the patients’ blood sugar is above average. Diabetes Mellitus can cause an abundance of comorbidities, from viral infection until metabolic abnormalities. The increased risk of infections is mostly because diabetes mellitus changes how the body works. The changes range from changes in mechanical barriers (humoral immunity) and cellular changes (cellular immunity), the changes of the humoral immunity that can increase the chance of protracting pulmonary tuberculosis. Objective: The purpose of this study was to describe the characteristics of diabetes mellitus in pulmonary tuberculosis in Dr. Soetomo General Academic Hospital, Surabaya, Indonesia from January to December 2016. Materials and Methods: The research method used was an observational study using a cross-sectional design conducted in Central Medical Record for hospitalized patients, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. The diabetes mellitus patients’ data collected from the medical records of Dr. Soetomo General Academic Hospital, Surabaya, Indonesia in 2016 were 1,410 and 11 of them were also diagnosed with pulmonary tuberculosis. The final data taken were from 67 out of 115 patients due to the incomplete medical record. Results: According to the data, the most of the diabetic patients with pulmonary tuberculosis were male, age of 51-75 years old, and worked in private sector. Conclusion: There was a significantly higher number of diabetes mellitus with pulmonary tuberculosis patients in older age, males, and private-sector workers. Diabetic patients with pulmonary t

Published: January 2022

Highlight:1. The widow will outsource childcare to other people, such as the widow's mother, stepmother, aunt, or other relatives who believe they know more about childcare after the wife's death.3. There was a significant relationship between widower’s age and the number of children affecting parenting style and remarriage decision.Abstract:Background: The high maternal mortality ratio automatically represents the highest number of widowers in Indonesia. The change of status from a husband to a widower does not rule out the possibility of being able to change his role and function in the family. Objective: To describe that the widower’s age and the number of children have an impact on the parenting style and the desire to remarry. Materials and Methods: This study was an observational study with a cross-sectional design. Husbands who had been left by their wives for two years or more owing to maternal death and had one or more children before the wife's maternal death were the subjects of this study. Widower’s age, as well as kid’s parenting patterns before the death of the mother were recorded. This study was likewise subjected to an ethics review and relied on informed consent. Results: Widowers who had one child before their wife's death and decided to remarry accounted for 7 subjects (87.5%), while those who did not remarry accounted for 5 (31.3%). On the association between a widower’s age and child-rearing practices, there were two respondents (40%) who chose to entrust their children’s care to someone else or not to be cared by themselves. Conclusion: There was a significant relationship between widower’s age and the number of children and the parenting style and remarriage decision. Single parents who decided to remarry were single parents at a relatively younger age.

ABSTRACT
Since the discovery of giant Aptian pre-salt reservoirs in Brazilian margin basins, the study of lacustrine carbonates has drawn great attention from the scientific community. Comparatively, minor attention was given to the characterization and genesis of the Mg-silicates (e.g., stevensite, kerolite) which are commonly associated with these carbonates. A systematic petrological study was performed in the Aptian Barra Velha Formation (BVF) within distinct structural compartments of the giant Lula Field in the Santos Basin, in order to recognize the patterns of primary formation and diagenetic alteration of these Mg-silicates. Mg-silicates occur as peloids, ooids, intraclasts, and fine-grained laminated deposits, either mixed in variable proportions with other particles, such as carbonate bioclasts and volcanic rock fragments, or constituting specific intrabasinal deposits. In the BVF interval, clay peloids and laminated deposits are associated with spherulitic and fascicular calcite aggregates, as substrate and hosts for these precipitates. Ooids are interpreted as formed at the sediment–water interface by the nucleation of concentric envelopes on the surface of particles (heterogeneous nucleation), through repeated rolling under gentle wave and current action. Laminated deposits, interpreted as precipitated directly from the water column (homogeneous nucleation) in highly supersaturated and low-hydrodynamic-energy environments, constitute extensive deposits in the BVF. Peloids were probably formed in intermediate energy conditions. Some ooidal arenites show porosity from the dehydration and contraction, and/or the dissolution of ooids. In some rocks, these pores are filled with fibrous calcite, while the remaining Mg-silicates are replaced by dolomite, calcite, or silica. A similar diagenetic pattern occurs in the laminated deposits, where magnesite and dolomite fill shrinkage pores formed along their characteristic wavy laminae. Owing to their elevated solubility, most of the Mg-silicates were dissolved, or intensely replaced by calcite, dolomite, or silica. The detailed petrologic analysis indicates that the original volumes of Mg-silicates were substantially larger, and that their deposition was widespread in the basin, including on structurally high areas. The types and intensity of diagenetic alteration of the Mg-silicate deposits are distinct for each structural compartment, being more intense towards the highs and closer to the overlying evaporites, which imposed a strong influence on reservoir quality.

Abstract
Development of the tight gas Khazzan Field in Sultanate of Oman has progressed through an extensive learning curve over many years. Thereby, the hydraulic fracturing design was fine-tuned and optimized to properly fit the requirements of the challenging Barik reservoir in this area. In 2018, BP Oman started developing the Barik reservoir in the Ghazeer Field, which naturally extends the reservoir boundary south of Khazzan Field. However, the Barik reservoir in the Ghazeer area is thicker and more permeable than in the Khazzan Field; therefore, the hydraulic fracturing design required adjustment to be optimized to directly reflect the reservoir needs of the Ghazeer Field.
A comprehensive hydraulic fracturing design software was used for this optimization study and sensitivity analysis. This software is a plug-in to a benchmark exploration and production software platform and provides a complete fracturing optimization loop from hydraulic fracturing design sensitivity modelled with a calibrated mechanical earth model to detailed production prediction using the incorporated reservoir simulator. One of the stimulated wells from Ghazeer Field was used as the reference for this study. The reservoir sector model was created and adjusted to match actual data from this well. The data include fracturing treatment execution response, surveillance data such as radioactive tracers, bottomhole pressure gauge, and pressure transient analysis. Reservoir properties were also adjusted to match long-term production data obtained for this reference well. After the reservoir model was fully validated against actual data, multiple completion and fracturing scenarios were simulated to estimate potential production gain and thus find an optimal hydraulic fracturing design for Ghazeer Field.
Many valuable outcomes can be concluded from this study. The optimal treatment design was identified. The value of fracture half-length versus conductivity was clarified for this area. The comparison between single-stage fracturing versus multistage treatment across the thick laminated Barik reservoir in a conventional vertical well was derived. The drainage of different layers with variable reservoir properties was compared for a range of different scenarios.
Numerical Simulation Study of Proppant Transport in Cross Fractures

Published: January 2022

Abstract
Hydraulic fracturing technology is an important means to stimulate unconventional reservoirs, and the placement morphology of proppant in cross fractures is a key factor affecting the effect of hydraulic fracturing. It is very important to study the proppant transport law in cross fractures.
In order to study the proppant transportation law in cross fractures, based on the CFD-DEM method, a proppant transport model in cross fractures was established. From the two aspects of the flow field in the fractures and the morphology of the proppant dune, the influence of the natural fracture approach angle, the fracturing fluid viscosity and injection rate on the proppant transport is studied. Based on the principle of hydropower similarity, the conductivity of proppant dune under different conditions is quantitatively studied.
The results show that the natural fracture approach angle affects the distribution of proppant and fracturing fluid in natural fractures, and further affects the proppant placement morphology in hydraulic fractures and natural fractures. When the fracturing fluid viscosity is low and the displacement is small, the proppant forms a "high and narrow" dune at the entrance of the fracture. With the increase of the fracturing fluid viscosity and injection rate, the proppant settles to form a "short and wide" placement morphology. Compared with the natural fracture approach angle, the fracturing fluid viscosity and injection rate have a more significant impact on the conductivity of proppant dune.
This paper investigated the proppant transportation in cross fractures, and quantitatively analyzes the conductivity of proppant dunes with different placement morphology. The results of this study can provide theoretical guidance for the design of hydraulic fracturing.

Abstract
Well K1002 is the first highly deviated ultra-deep well in Tarim Oilfield of China, with the reservoir depth 7060m and the well deviation of 60° ∼ 77.6° in the fractured interval. Because of large deviation angle, high breakdown pressure and in-situ stress, poor effectiveness of natural fractures, large reservoir thickness, it is difficult and risky to implement hydraulic fracturing. In this paper, the fractured well was taken for a case study to illustrate the holistic optimization to guarantee the treatment success, a world-wide difficulty with high engineering risk.
For figuring out a reasonable treatment design, comprehensive lab experiments and numerical simulation were conducted to analyze and benchmark the reservoir characteristics, rock mechanics and geological model. Systematic study on reducing breakdown pressure, development of natural fractures evaluation, multi-size combination of diverting agent, separated layer stimulation and fracture parameters optimization, treatment fluid formulation, proppant screening and operation program were carried out.
Considering the wellbore trajectory and rock mechanics characteristics of well K1002, a breakdown pressure prediction model was established to optimize the perforation orientation. The best perforation orientation was 28° and 208°, the worst perforation orientation was 148° and 328°, and the breakdown pressure range was 168-175MPa with 60° phase angle. Combination with "imaging logging (0-3m) + far detection acoustic logging (0-30m) + geomechanics (0-300m)", the comprehensive evaluation and prediction of natural fractures in near wellbore area and far wellbore area were realized. Based on this, the stimulation technology of "mechanical layering + diverting agent" was optimized to connect the fracture development zone in near wellbore and far wellbore area. According to the Tight Packing Theory, the idea of "multi-size particles combination of diverting agent" was put forward. Through the experiment study, the combination of 1-5mm and 5-10mm particles was optimized, and the optimal chart of diverting agent size combination was made under different reservoir temperatures. For the fracturing job, totally 2562m3 KCL weighted fracturing fluid and 159.2m3 ceramic proppant of 40-70 mesh were pumped. The operation parameters were in reasonable agreement with the design. The initial test production was 10 times higher than before.
The experience gained in this case study has some guiding significance for improving the success rate of hydraulic fracturing treatments in the highly deviated ultra-deep well and for effectively developing such fractured tight sandstone reservoirs, both theoretically and practically.

AbstractPDO operates about 200 deep gas wells in the X field in the Sultanate of Oman, producing commingled from the Barik gas-condensate and Miqrat lean gas reservoir completed by multiple hydraulic fracturing. Their inflow performance relation (IPR) is tracked to diagnose condensate damage, hydraulic fracture cleanup and differential reservoir pressure depletion. The best IPR data is collected through multi-rate production logging but surface production data serves as an alternative. This paper describes the process of deriving IPR's from production logging and surface production data, and then evaluates 20 years of historic IPR data to quantify the impact of condensate damage and condensate cleanup with progressive reservoir pressure depletion, to demonstrate the massive damage and slow cleanup of hydraulic fractures placed in depleted reservoirs, to show how hydraulic fractures facilitate the vertical cross-flow between isolated reservoir intervals, and to highlight that stress-dependent permeability does not play a major role in this field.
Best Practices in DFIT Interpretation: Comparative Analysis of 62 DFITs from Nine Different Shale Plays
Authors: Mcclure Mark , Fowler Garrett , Picone Matteo 
Published: January 2022

AbstractIn URTeC-123-2019, a group of operators and service companies presented a step-by-step procedure for interpretation of diagnostic fracture injection tests (DFITs). The procedure has now been applied on a wide variety of data across North and South America. This paper statistically summarizes results from 62 of these DFITs, contributed by ten operators spanning nine different shale plays. URTeC-123-2019 made several novel claims, which are tested and validated in this paper. We find that: (1) a ‘compliance method’ closure signature is apparent in the significant majority of DFITs; (2) in horizontal wells, early time pressure drop due to near-wellbore/midfield tortuosity is substantial and varies greatly, from 500 to 6000+ psi; (3) in vertical wells, early-time pressure drop is far weaker; this supports the interpretation that early- time pressure drop in horizontal wells is caused by near-wellbore/midfield tortuosity from transverse fracture propagation; (4) the (not recommended) tangent method of estimating closure yields Shmin estimates that are 100-1000+ psi lower than the estimate from the (recommended) compliance method; the implied net pressure values are 2.5x higher on average and up to 5-6x higher; (5) as predicted by theory, the difference between the tangent and compliance stress and net pressure estimates increases in formations with greater difference between Shmin and pore pressure; (6) the h-function and G-function methods allow permeability to be estimated from truncated data that never reaches late-time impulse flow; comparison shows that they give results that are close to the permeability estimates from impulse linear flow; (7) false radial flow signatures occur in the significant majority of gas shale DFITs, and are rare in oil shale DFITs; (8) if false radial signatures are used to estimate permeability, they tend to overestimate permeability, often by 100x or more; (9) the holistic-method permeability correlation overestimates permeability by 10-1000x; (10) in tests that do not reach late-time impulse transients, it is reasonable to make an approximate pore pressure estimate by extrapolating the pressure from the peak in t*dP/dt using a scaling of t^(-1/2) in oil shales and t^(3/4) in gas shales. The findings have direct practical implications for operators. Accurate permeability estimates are needed for calculating effective fracture length and for optimizing well spacing and frac design. Accurate stress estimation is fundamental to hydraulic fracture design and other geomechanics applications.
