Published: June 2023

Background:Persons living with disabilities have difficulty finding work, are discriminated against, and have high rates of unemployment. They face many barriers, including stereotyped perceptions that prevent employers from hiring people with disabilities.Objective:To promote equality in the employment market and to lower barriers, we at Gal College in cooperation with the School of Social Work at Tel-Aviv University developed an innovative multidimensional integrative program.Methods:The program offers a beneficial learning experience that integrates professional studies with a personal rehabilitation process as the students themselves cope and live with their disability. The program graduates then become rehabilitators who serve as employment placement workers and rehabilitation facilitators for others coping with disability. All the students completed at least 12 years of school, were between the ages of 25 and 55, and were out of work for a long period of time.Findings:The quantitative results reveal a high placement rate for program graduates. Over the years, this rate has increased from 79% to 100%, testifying to the program’s success.Conclusions:Analyzes the dynamic learning model as well as the quantitative results and the successful transition from rehabilitee to rehabilitator.

Published: June 2023

Background:At the start of the COVID-19 pandemic, the in-person clinical exposure of Physical Therapy (PT) interns in various regions of the world, including the Philippines, was suspended for safety reasons. To resume internship training, telerehabilitation was adopted in several academic institutions, such as the Cebu Doctors’ University (CDU). However, our Rehabilitation Sciences faculty and students were unprepared for the sudden shift to virtual teaching-learning methods.Objective:We hereby present our local experience in incorporating telerehabilitation in our clinical training and patient service.Methods:We conducted the following steps toward redesigning our PT internship curriculum: (1) review of existing national guidelines on flexible learning; (2) analysis of capabilities and limitations of our students and teachers to engage in flexible learning; and (3) planning for means to capacitate them for shifting to flexible learning.Findings:In our curricular redesign, we adapted the Flexible Learning Framework, consisting of the following components: students’ virtual experience, faculty and staff development, flexible learning instructional design, shared and aligned governance, institutional policy and infrastructure, and quality assurance.Conclusion:Due to the lack of formal inclusion of telerehabilitation in the national PT internship curriculum pre-pandemic and the need to quickly update our clinical program during the pandemic, our experience in evaluating and building our capacities toward developing a telerehabilitation program can serve as an example for other rehabilitation disciplines and academic institutions amid and beyond the pandemic.

PURPOSE:Retinitis pigmentosa (RP) is associated with visual impairment and negative effects on patients’ abilities and independence in their life. This study aims at exploring the process of self-empowerment among individuals with RP.METHOD:This study was conducted using a grounded theory design. Participants were RP-afflicted individuals.RESULTS:“Erosion of personal and social abilities” was the main problem of participants. The context in which the process happened was “The social poverty of the context.” Their main strategy for managing this problem was “self-improving,” which was associated with improved personal and social status. The core category of the study was “participatory self-empowering in the unfavorable context of society.”CONCLUSIONS:Affliction by RP in an inappropriate social environment causes individuals different problems. Therefore, individuals modify their lifestyles, develop their social abilities, adapt to their environment, and seek help in order to manage their problems. Holistic multidisciplinary interventions based on the needs of patients are recommended for their empowerment.

Equations with Nonlinear Noise
Authors: Liu Xin , Li Yan jiao 
Published: June 2023

At present paper,
we aim to study the long-time behavior of a stochastic semi-linear degenerate parabolic equation on bounded or unbounded domain and driven by a nonlinear noise and defined. Since the theory of pathwise random dynamical systems can not be applied directly to the equation with nonlinear noise, first, we establish the existence of weak pullback mean random attractors for the equation by applying the theory of mean-square random dynamical systems;
then, we prove the existence of (pathwise) pullback random attractors for the
Wong-Zakai approximate system of the equation. In addition, we establish the upper semicontinuity of pullback random attractors for the Wong-Zakai approximate system of the equation under consideration driven by a linear multiplicative noise.
Research on the Characteristics of Acoustic Emission Activities of Granite and Marble under Different Loading Methods
Authors: Sun Yongshuai , Yu Fei , Lv Jianguo 
Published: June 2023

AbstractAt present, there is no corresponding standard for the engineering application of rock acoustic emission technology. To better apply acoustic emission technology to engineering practice, in this paper, the acoustic emission characteristics of different rock samples of marble and granite under uniaxial compression were analyzed by indoor acoustic emission test, the factors affecting the acoustic emission characteristics of rocks are studied, and the failure mechanism and damage characteristics of rock are discussed. The research contents include analyzing the curve fitting relationship between the acoustic emission event rate, the number of events, the stress time, and study of the similarities and differences of acoustic emission characteristics of marble and granite; analysis of damage characteristics of marble and granite based on acoustic emission parameters; by analyzing the relationship between the Felicity ratio of different rocks and the stress level during cyclic loading, the applicability of studying the Kaiser and Felicity effects of rocks; variation of acoustic emission event rate and rock peak intensity under different loading methods and loading rates. The results show that the acoustic emission of marble and granite has experienced the initial compaction zone, the rising zone, the peak zone, and the falling zone, and the two kinds of rocks have different acoustic emission phenomena in different stages, and the duration of each stage is also different; before the instability of the two kinds of rocks, there is a quiet period of acoustic emission, and the higher the rock strength, the longer the duration of this quiet period, which means that the calm period can be used as a precursor feature of rock mass instability for disaster prediction; during the cyclic loading process of rock, the damage development law is divided into three stages: initial stage, stable stage, and instability stage. When the Kaiser effect did not appear for the two rock stresses before 20%, between 20% and 70% of the peak strength, the Kaiser effect is obvious. When the stress exceeds 80% of the peak value, the Kaiser effect fails, and the Felicity effect appears; the variation of the loading rate affects the variation of the acoustic emission event rate, and the increase of the loading rate leads to aggravated rock damage. The theoretical stress-strain curve can reasonably reflect the actual stress-strain characteristics of rock by combining the number of acoustic emission events with the rock damage model. The results are consistent with the acoustic emission test, which verifies the inevitable relationship between acoustic emission and damage to the rock.
Investigating the Feasibility of Reusing Lower Salinity Produced Water for Waterflooding of Carbonate Reservoirs Containing Hypersaline In-Situ Brine-A Study Using Field Samples

Abstract
Synthetically prepared low-salinity brines are usually used for mechanistic and improved oil recovery studies in carbonate rocks. However, in actual onshore field applications, using nearby produced water with low or seawater-like salinities could potentially yield optimized waterflooding economics. In this work, field samples from Central Kansas Uplift oil production formations were acquired and tested for the potential increase in oil production from mature oil reservoirs. Geochemical compatibility testing of fluid-fluid interaction between the hypersaline produced water (PW-1) from Lansing Kansas City reservoir and seawater-like produced water (PW-2) from the Arbuckle formation showed no evidence of potential scale formation. Furthermore, seawater-like PW-2 altered the limestone rock wettability represented by lowering the contact angle from 148° (oil-wet) for PW-1 to 119° (intermediate wet) for PW-2. Wettability alteration was further supported by the Amott-Harvey index. At the oil-brine interface, equilibrium interfacial tension slightly increased from 8.35 mN/m2 for PW-1 to 10.87 mN/m2 for PW-2. However, the surface elasticity was calculated to increase from 43.3 mN/m2 to 74.8 mN/m2 for hypersaline PW-1 and seawater-like PW-2, respectively, indicating better stability at the oil-brine interface, which could reduce crude oil snap-off and improve sweep efficiency. Approximately 6.7% incremental recovery due to the injection of seawater-like PW-2 was observed in the secondary mode. Therefore, the use of geochemically compatible seawater-like produced water with carbonate rocks hosting hyper-saline water could improve oil recovery by altering the rock wettability and suppressing crude oil snap-off, hence serving as a viable economic option for mature oilfields.

Abstract
Sulfide and carbonate mixed scales are ubiquitous in oilfield production and injection system with low corrosion resistant carbon steel equipment and pipeline. Previously, such conditions were generally treated as a corrosion problem rather than a scale problem, and the interactions between steel corrosion and mineral scale formation remain unclear. In this study, the iron sulfide and iron carbonate mixed scaling and corrosion behaviors were investigated simultaneously under simulated produced water environments. The influence of carbonate to sulfide ratios and calcium concentration in the brine was investigated. It was found that the iron sulfide (FeS) scale was always formed on the mild steel surface under various brine compositions due to the fast kinetics of the sulfide scale precipitation and sour corrosion. While with the presence of calcium, the carbonate scale was easier to form, and this carbonate scale layer would be crucial to promoting calcium carbonate deposition. The iron carbonate (FeCO3) precipitation kinetics was a diffusion-controlled reaction that can be accelerated by higher temperature and calcium concentrations. The conventional scale inhibition and corrosion inhibition methods were also tested. The combination of scale inhibitor, corrosion inhibitor, and dispersant chemical combos successfully prevents the deposition formation on the mild steel surface and significantly reduces the corrosion rate. This study demonstrated the complicated interaction between the sulfide and carbonate scale and also bridged the scale and corrosion, which could help to develop a better scale and corrosion control strategy under complicated field conditions.
A Novel Star Polymer based Fluid Loss Control Additive for Non-Aqueous Drilling Fluids

Published: June 2023

Abstract
Non-aqueous fluids (NAF) are considered as efficient and reliable drilling fluid systems for challenging wellbore conditions, such as high-temperature drilling operations. NAFs require fluid loss control additives to reduce filtration loss into the formation with minimum filter cake thickness. Polymer developed in this work demonstrated exceptional properties such as high dispersibility, good thermal stability and low plastic viscosity, when compared with traditional natural and synthetic-based fluid loss control additives (e.g., gilsonite).
We have utilized a synthetic molecular optimization process to precisely adjust the hydrophilic-lyophilic balance (HLB) by altering the ratio of hydrophilic to hydrophobic monomers. This has allowed us to achieve an HLB that facilitates easy dispersion within NAF formulations. The star polymer was produced using a controlled/radical polymerization technique called Reversible Addition Fragmentation Chain Transfer polymerization (RAFT). The properties of the NAFs, such as rheology, fluid loss, mud cake thickness, and emulsion stability, were evaluated and compared with commercially available fluid loss control additives under simulated downhole pressure and temperature conditions. The chemical structure and thermal stability of the star polymer were analyzed using spectroscopy and thermogravimetric analysis.
The spectroscopic studies confirmed the formation of desired polymeric structures and the molecular weight desired. Star-polymer synthesized herein has excellent thermal stability up to 450 °F with great fluid loss control and ultrathin filter cake for NAF systems for mud weight ranging from 10 to 17 lbm/gal. The star polymer also improves emulsion stability. Plastic viscosity (PV) is usually increased with the addition of commercially available fluid loss control additives; however, star-polymer had a negligible effect on PV. Results for both diesel and mineral oil-based mud systems will be presented. High-temperature high-pressure viscometer (Fann 77) was used to study rheological properties at up to 350 °F and 10,000 psi.
Our recent work has resulted in the creation of a cutting-edge star polymer (NSP) for use in the industry's next-gen high-performance fluid loss additives. The polymer network can be efficiently synthesized and scaled up for commercial production, providing engineers with an improved solution for drilling high-temperature wells (up to 350°F) with reduced plastic viscosity and increased emulsion stability, while also providing excellent fluid loss control.

Authors: Varadaraj Ramesh , Fontenot Kristina 
Published: June 2023

Abstract
The technical feasibility of using oxygenated solvent mixtures as an environmental and ecological friendly alternative to aromatic hydrocarbon and terpene solvents for removal of organic deposits from surfaces has been demonstrated. Micro-heterogeneous solvents were prepared using mixtures of di-alkyl ethers and 2-alkyl alkanols. These micro-heterogeneous solvents exhibit unique properties and are effective in solubilizing and removing organic asphaltenic hydrocarbon deposits from surfaces. The main applications of micro-heterogeneous solvents are in organic deposits removal from wellbores and near wellbore regions, heavy oil recovery from oil sands and oily sludges, and heavy oil processing equipment cleaning.
Analytical Techniques Unveil the Nature of Waxphaltenes Interactions in Solution and with Carbonates and Sandstones

Published: June 2023

Abstract
Several studies have demonstrated the nature of wax and asphaltene interactions and their impact on crude properties, including deposition characteristics. Laboratory and field studies have confirmed organic deposits from offshore oil wells containing asphaltenes and paraffins coprecipitated together to form solid aggregates. These can be described as "Waxphaltenes." This study used different techniques to understand better the properties of waxphaltenes from an offshore operation and how they interact with different rock mineralogy. It was found that mixing crude oil with acetone or methyl ethyl ketone (MEK) is highly efficient in the precipitation and isolation of heavy organics and other polar fractions than the traditional use of pentane or heptane from bulk hydrocarbon fluid. GC, FTIR, NMR, and elemental analysis revealed the composition characteristics of isolated organic solids. ATR-FTIR and AFM-IR methods were used to monitor the deposition of oil and organics on the surface of carbonate and silicate rocks. Water imbibition and solvent wash could remove some of the waxphaltenes dominated deposit from the surface but leave a key monolayer of organics adhered to the surface via hydrogen- or ionic bonding, which act as hydrophobic film. A plausible mechanism of such film formation may include di-or multivalent ions as bridging agents to bind with carboxylate and hydroxyl groups present in organic fractions.
