Published: July 2022

To compare the tear function among newly diagnosed Polycystic Ovary Syndrome subjects and Polycystic Ovary syndrome under treatment. Seventy Polycystic Ovary Syndrome (PCOS) subjects were included in the study with age ranging from 18 to 35 years, consisting of 35 subjects in group 1 as newly diagnosed PCOS and 35 in group 2 as PCOS under treatment. The subjects underwent comprehensive eye examination and slit lamp examination. Participants were asked to answer the ocular surface disease index (OSDI) questionnaire to know the symptoms of dry eye and the following tests such as Schirmer’s 1 and 2, Tear film break-up test (TBUT) was performed to know the tear functions. No difference was found in OSDI scores when comparing two groups. Both Schirmer’s test and TBUT test were significant. When both the groups are compared Schirmer’s 1 p value for right eye is 0.001, left eye is 0.023.Schirmer’s 2 p value for right eye is 0.002, left eye is 0.001.However TBUT p value for right eye and left eye is 0.00. Through our findings we suggest that patients who are under treatment for PCOS, should take ophthalmic examination, especially for dry eye.

The main purpose of our study is to provide a general view of various ocular manifestations observed in type 2 diabetes mellitus patients. Ocular manifestations observed in our study not only include cataract and retinopathy but also other anterior and posterior segment ocular manifestations and their epidemiology. We wanted to evaluate the different ocular manifestations in type 2 diabetes mellitus, its clinical profile, and its relationship between various risk factors. All cases with a known case of type 2 diabetes mellitus presented to the Tertiary Eye Care Centre, Telangana, in South India were examined in detail to know the various ocular manifestations. A prospective observational study was done. Patients who presented with diabetes were examined in detail, diabetes history, and further investigated to know anterior and posterior segment ocular manifestations. The study was conducted on 500 patients over 18 months from December 2018 to June 2020. All 500 patients were examined in detail. Ocular manifestations observed in type 2 Diabetes mellitus include cataract, diabetic retinopathy, glaucoma, keratitis, retinal vascular occlusion, ophthalmoplegia, lid lesions, ischemic optic neuropathy, age-related macular degenerations. Diabetes mellitus is an important health problem that causes significant morbidity due to specific microvascular complications such as retinopathy, nephropathy, and neuropathy, and macrovascular complications such as ischemic heart disease, and peripheral vasculopathy. Ocular manifestations were more likely to occur in both eyes in diabetes patients. Treatment and visual rehabilitation vary for different ocular manifestations. A thorough early ocular evaluation of patients and management is of utmost importance to prevent further visual impairment.

IMPLEMENTASI TEORI BELAJAR HUMANISTIK CARL R. ROGERS PADA PEMBELAJARAN PENDIDIKAN AGAMA ISLAM
Authors: Umam Muchamad Chairul 
Published: July 2022

Education so far has not yet applied Humanistic learning which is actually very important because it has a goal that can shape students to be human so the researchers chose the topic of Humanistic learning so that education in schools can understand the potential possessed by students not only nature only positive fields. Humanistic learning initiated by Carl R. Rogers aims to shape learners' personalities not only in the cognitive aspect but more emphasized in the attitudes and social aspects, he also advocates an educational approach should try to make learning and teaching more human, more personal, and meaningful.
Humanistic theory is a learning theory that tends towards philosophy, so that its implementation in learning PAI is still difficult to do in practical and operational learning steps, but the contribution is so large. The concepts, ideas, taxonomies of objectives that have been formulated can help educators and teachers in understanding human nature. This will be able to assist them in determining learning components such as goal formulation, material determination, selection of learning strategies, and development of evaluation tools, towards the formation of the aspired human.
The research method used by researchers is qualitative by looking at social phenomena and understanding the meaning of human behavior. This research is descriptive in this study trying to explain or illustrate the implementation of Carl R Rogers' humanistic learning theory on Islamic religious learning.
Experimental Study on Damage Evolution Characteristics of Coal Samples under Impact Load under Different Surrounding Pressures

Published: July 2022

Abstract
To study the response characteristics of coal samples to impact load under different surrounding pressures, the self-developed magnetic drop hammer impact device was used to measure the change of ultrasonic wave velocity before and after drop hammer impact, the internal damage of coal samples was quantitatively characterized, and then, the damage factor, damage difference, and crack development direction of briquette samples were analyzed. Based on the Griffith strength theory, the relationship between stress intensity factor, crack development angle, and surrounding pressure ratio of coal samples with composite cracks was deduced. It was found that a certain surrounding pressure would slow crack expansion and reduce the amount of damage increase. The damage degree of briquette samples caused by impact load under no surrounding pressure is the largest, followed by that at the surrounding pressure ratio of 0 and 2 and that at the surrounding pressure ratio of 1 is the smallest. When the amount of damage difference of the sample is positively correlated with the number of impacts, the crack development is directional; when the amount of damage difference of the sample is nonpositively correlated with the number of impacts, the direction of crack development is random. It is therefore reasonable to predict the direction of crack expansion by the trend in the amount of damage difference. Besides, the difference in impact load between briquette and raw coal samples under different surrounding pressure ratios was discussed, and the fractal dimension of the sample surface under different surrounding pressure ratios was compared and analyzed. It is found that the fractal dimension of raw coal is larger than that of briquette, indicating that the crack development of raw coal is higher after impact; the damage amount of raw coal is larger than that of briquette, indicating that raw coal is easier to be damaged after impact.
Phase Behavior in Nanopores and Its Indication for Cyclic Gas Injection in a Volatile Oil Reservoir from Duvernay Shale

Published: July 2022

Abstract
Duvernay shale spans over 6 million acres with a total resource of 440 billion barrels’ oil equivalent in the Western Canada Sedimentary Basin (WCSB). The oil recovery factors typically decrease with the decreasing of gas-oil ratio (GOR) in oil window of Duvernay shale. The volatile oil recovery factors are typically 5–10%. Enhanced oil recovery technologies should be applied to improve the economics of the reservoirs. In this paper, the volatile oil from the Duvernay shale was taken as an example for phase behavior study. We analyzed the nanopore confinement on phase behavior and physical properties of Duvernay shale oil. The shift of critical properties was quantified within nanopores. With the confinement of nanopores, the viscosity, density, and bubble point pressure of the oil decrease with the shrinking of the pore size. Minimum miscibility pressure (MMP) was calculated for different injected gases. The MMP from high to low is N2&gt;CH4&gt;lean gas&gt;rich gas&gt;CO2. In the case of injecting the same gas component, the MMP decreases as the pore size decreases. The wellhead rich gas is suggested to be the main gas source for gas injection in Duvernay shale. The formation pressure should be rapidly increased to the MMP and maintained close to it, which would help to improve the effect of gas injection and enhance shale oil recovery. This paper can provide critical insights for the research of shale oil gas injection for enhanced oil recovery.

Study Reviews Recent Polymerflooding Advances in China
Authors: Carpenter Chris 
Published: July 2022

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 200084, “Recent Advances of Polymerflooding in China,” by Hu Guo and Kaoping Song, China University of Petroleum, and Yuming Wang, Daqing Oilfield Company, et al. The paper has not been peer reviewed.
Polymerflooding is one of the more promising chemical enhanced oil recovery (EOR) techniques that features high incremental oil recovery factor, low cost, and wide reservoir applicability. This paper helps clarify ideas regarding polymerflooding implementation based on theory and practice in China.

Introduction
Laboratory studies aimed at increasing understanding of polymerflooding involve criteria for matching polymer with porous media, the polymer viscoelasticity effect on residual oil saturation (ROS), and displacement efficiency and synthesis of new polymers with better viscosifying capacity compared with typical partially hydrolyzed polyacrylamide (HPAM). The plugging of injectors in many oil fields is becoming increasingly common in many commercial blocks. This problem is especially serious for high-concentration polymer-injection blocks in fields such as Daqing, Xinjiang, and Henan. Understanding this phenomenon involves aligning the polymer and porous-media parameters such as permeability and pore size. Actual reservoir pressure distribution also must be considered. Because modern chemical EOR is based on ultralow interfacial tension (IFT) and minimum mobility ratio theory, the idea of combining the benefits of reducing IFT and increasing displacing-phase viscosity leads to a synthesis of amphiphilic polymers, which have features of both polymers and surfactants. This new type of polymer is sometimes called polymeric surfactant in China.

Published: July 2022

Abstract
In a large-scale networking scenario with massive distribution of devices, data is independently generated and maintained by multiple domains. In order to solve the problem of isolated data island in multi-domain, this paper designs a multi-domain data sharing model based on consortium chain. Aiming at the problems of low efficiency and the less consideration of intra-domain consensus processes in traditional data sharing schemes, this paper optimizes the security and efficiency of data sharing from two parts: inter-domain chain and intra-domain chain. In order to ensure the fine-grained, dynamic and secure access strategy in inter-domain chain, this model combines the attribute-based access control model (ABAC) with smart contract, and a permission grading mechanism is designed to solve the problem of low retrieval efficiency in this access control model through reducing the retrieval range by grading and matching Policy set. In view of the problem of high delay of node consensus in the large-scale networking environment of intra-domain chain, a Layered Practical Byzantine Fault Tolerance optimization (LPBFT) algorithm with introducing a reputation model is designed, which greatly improves the efficiency and security of the intra-domain consensus. The consortium chain model is designed and implemented from the perspectives of inter-domain and intra-domain, which optimized the security and efficiency of the multi-domain data sharing model. Finally, this paper implements a prototype system with the Hyperledger Fabric platform, and verifies the validity of this model from the access control within the inter-domain and the consensus algorithm within the intra-domain separately.

Abstract
Background: Uterine rupture or dehiscence during trial of labor after cesarean is a cause of great concern for both parturitions and physicians. Although the risk-factors for uterine rupture are well-established, surgical site infection in the first cesarian-section has not been investigated in depth.Aim: To evaluate the relation between peripartum infection after caesarean delivery to uterine dehiscence or rupture at the subsequent delivery.Methods: A retrospective case-control study. The study group included women with a prior caesarean delivery and proven dehiscence, or uterine rupture diagnosed during their subsequent delivery. The control group were women who had a successful vaginal birth after cesarean section without evidence of dehiscence or uterine rupture. We compared the rate of infection during the cesarean delivery between the two groups. Findings: A total of 168 women were included, 71 with uterine rupture or dehiscence and 97 with successful vaginal birth after cesarean section. The rate of peripartum infection at the first caesarean delivery was significantly higher in the study group compared to the control group (22.2% vs. 8.2%,p=0.013). Endometritis had the highest correlation to uterine rupture (9.8% vs. 0%,p=0.02)Discussion: Peripartum infection in the first caesarean delivery, may be an independent risk-factor for uterine rupture in a subsequent delivery. Compared to other infections, endometritis may pose the greatest risk for uterine rupture or dehiscence.Conclusion: when consulting with a patient on repeat cesarean section vs. trial of labor after cesarian, endometritis after the previous surgery should be included among the considerations, along with other traditional risk-factors.

Abstract
Electrospun nanofibers can be used as membranes for cell culture applications. In addition to their high performance and cost-effectiveness, nanofibers can be made from a variety of polymers and utilized in microfluidic devices as separators, filters, and for biological assessments. In this paper, we have employed a two-pump technique to prepare a hybrid nanofiber-based membrane with a biocompatible polyethylene terephthalate (PET), polydimethylsiloxane (PDMS), and collagen. The introduction of collagen creates a suitable substrate for cell attachment and decreased hydrophobicity. To sustain collagen on the fibers, the membranes were treated with glutaraldehyde vapor and then detoxified. The membrane integrity and structure were evaluated using SEM, AFM, contact angle analyzer, FT-IR, and tensile apparatus. In addition, cell attachment capabilities and cytocompatibility were examined using SEM and AlamarBlue, respectively. The membrane was cased in a PDMS-based microfluidic device consisting of upper and lower channels. Our findings suggest that the incorporation of PET and PDMS provides a superior bonding capability and prevents unwanted leakage. Then, Human Umbilical Vein Endothelial Cells (HUVECs) were cultured on both sides of the proposed membrane inside the device. To simulate the dynamic environment and induce cellular shear stress, the culture medium was flown through the channel and the conditions were kept overnight inside an incubator. Cellular staining (Acridine Orange and Propidium Iodide, as well as DAPI) and further evaluation of cellular adhesion suggest that cells were well attached and viable inside the microfluidic device. The proposed membrane can be employed in fabrication of various biological barriers on-a-chip for the purpose of screening drugs, examining the effects of nanomaterials, and creation of in-vitro disease models.

Abstract
Objectives: Resin composites containing surface pre-reacted glass (S-PRG) were introduced to reduce demineralization and improve remineralization of the tooth structure. However, water diffusion within the material is necessary for its action, which can impair its overall physical-mechanical properties over time, including the color stability. This study aimed to evaluate the color stability and related degree of conversion (DC) of four resin composites.Materials and Methods: Discs (n=5/group) of microhybrid, nanofilled, nanohybrid, and S-PRG-based nanohybrid composites with two opacities were prepared. Color (CIELab and CIEDE2000) was evaluated after aging in grape juice. The DC was analyzed by using Fourier Transform Infrared Spectroscopy before and after photopolymerization. Data were statistically analyzed by using two-way analysis of variance and post-hoc least significant difference tests (P<.05).Results: In the color stabilityanalysis, the interaction between filler type and opacity was significant. S-PRG influenced color stability and DC.Conclusions: The nanohybrid resin composite presented favorable color stability and a greater DC, which is likely related to its organic content. S-PRG based nanohybrid resins require caution since its bioactive benefits depends on interaction with the environment that can be prone to impair color stability.Clinical Relevance: As color stability is mandatoryin specific regions, staining can jeopardize the esthetics of a resin composite. The use of nanohybrid composites with no or reduced BisGMA content and diluents may be more appropriate in these areas. Since materials containing S-PRG can offer relevant benefits, professionals need to balance their higher susceptibility to staining favoring other relevant properties.
