Authors: Carpenter Chris 
Published: July 2022

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 200051, “Successful Polymerflood Pilot Application in Lower-Permeability Heterogeneous Sandstone Reservoir in the South of the Sultanate of Oman,” by Hanaa Al-Sulaimani, SPE, Zainab Al-Rawahi, and Conny Velazco Quesada, Petroleum Development Oman, et al. The paper has not been peer reviewed.
This paper summarizes the performance of a polymerflooding pilot conducted in an unconsolidated sandstone reservoir in the south of Oman with the objective of extending the envelope of polymerflooding applications to lower-permeability (average 100 md) and highly heterogeneous reservoirs. Fiber-optics data acquisition has demonstrated clearly injection conformance improvement during the switch from water injection to polymer. In addition, approximately 10% of incremental oil recovery was obtained with an average water-cut reversal of 12% across the pattern where the total pattern recovery was greater than 30% (including the waterflood).

Introduction
Polymerflooding has been ongoing successfully in one of the major fields of southern Oman for almost 10 years. However, the operator aspires to extend the application boundary for the polymer to be applied in lower permeabilities, heavier oils, and different sweep strategies. The field of concern in this paper has an average permeability of 300–500 md, more than four times lower than the average permeability of the field with ongoing polymerflooding. Thus, a polymer pilot was designed to test the applicability of polymer technology in such an environment.

Abstract
Background: The aim of this work is to analyze the effect of a positive cumulative fluid balance and relative clinical indicators on the prognosis of patients with sepsis in the Xining area, China.Methods: The clinical data of 480 sepsis patients (313 males and 167 females, aged 52–77 (65) years) admitted between January 2017 and December 2019 were retrospectively analyzed. The APACHE II score, SOFA score, SIRS score and clinical laboratory test indicators of the patients were collected. Receiver operating characteristic (ROC) curves were used to analyze the sensitivity and specificity of each indicator in predicting the poor prognosis of patients with sepsis, and the maximum Youden index was used to determine threshold values. Cox regression analysis was performed to assess patient prognosis using data from patients with different fluid balances. Results: The following clinical indicators were significantly different between the 2 groups (P<0.05): APACHE II score, SOFA score, SIRS score, PCT, IL-6, BNP, CRP, PLT, BUN, CREA, Lac and total fluid balance from days 1 to 5. The area under the ROC curve (AUC) for total fluid balance from days 1 to 5 was 0.558, the cut-off value was 2120.5 mL, the sensitivity was 54.0%, and the specificity was 58.1%. The survival rates were different between the 2 groups (60.9% vs 48.9%, P<0.05). Total fluid balance was significantly higher in patients with septic shock and with Lac>2.0 mmol/L (P<0.05). Cox regression analysis indicated that APACHE II score, SOFA score, PLT score, Lac, and total fluid balance from days 1 to 5 were independent risk factors for poor prognosis.Conclusion: A positive fluid balance from days 1 to 5 after ICU admission was associated with poor patient outcomes and was an independent risk factor for poor patient prognosis.
Transplantation of acellularized amniotic membrane seeded with adipose-derived mesenchymal stem cells in a rat model of intrauterine adhesion
Authors: Li Chunbo , Guo Luopei , Hua Keqin 
Published: July 2022

Abstract
Background
Intrauterine adhesion (IUA) is characterized by the formation of fibrosis that prevent the regeneration of functional endometrium. Although various clinical approaches have been used to reconstruct the anatomy and promote the restoration of functional endometrium, the high risk of recurrence after surgery remains a major challenge. Application of tissue engineering offers new therapeutic strategies.
Aim
The aim of this study was to investigate the role of acellularized amniotic membrane (AAM) loaded with adipose-derived mesenchymal stem cells (ADSCs) in reducing IUA, and promoting the regeneration of damaged endometrium.
Methods
96 female Spargue-Dawley (SD) rats were randomly divided into four groups: sham operation group, IUA model group, experimental group treated with AAM, and experimental group treated with AAM loaded with ADSCs. Histological and immunohistochemical analysis were performed on 3, 7, and 14 days after surgery to evaluate the degree of uterine fibrosis and regeneration of injured endometrium. RNA sequencing and real-time polymerase chain reaction (RT-PCR) were used to explore the potential mechanism by which ADSCs modulated immune response and promoted endometrial regeneration.
Results
At 14 days after surgery, the endometrial thickening, the number of glands and the degree of reduced fibrosis in the ADSCs/AAM was higher than those in AAM group, and similar to sham group. RNA sequencing analysis showed that ADSCs can modulate local immune responses, and promote the formation of functional endometrium. Meanwhile, we found that transplantation of ADSCs significantly decreased the expression of pro-inflammatory cytokines expression (TNF-α and IL-1β), and increased the expression of anti-inflammatory cytokines (bFGF, and IL-6).
Conclusion
Our results demonstrated that AAM loaded with ADSCs can promote the regeneration of injured endometrium and reduce fibrosis formation. Meanwhile, ADSCs also regulated the immune microenvironment, which is beneficial to functional endometrial regeneration.

Abstract
The safety of subway tunnel construction using the PBA construction is the focus of attention at present. In this paper, based on the underground excavation project of Xin-cao section of Beijing Metro Line 19, the PBA construction process is studied by numerical simulation. The influence laws of surface settlement, structural deformation and internal force change after six construction procedures are compared and analyzed. The research results show that: after the excavation of small pilot tunnel, the extreme value of pavement settlement appears above the secondary lining vault, and the extreme value of safety factor of primary support structure of small pilot tunnel appears in the middle and both sides of the pilot tunnel vault; in order to ensure the construction safety, considering the displacement and internal force, it is suggested to excavate the middle pilot tunnel first, then construct the pile crown beam, and then excavate the two sides of the pilot tunnel Compared with other working conditions, this working condition can effectively control the pavement settlement and structural deformation, and the structural safety factor is the largest. The research results can provide a reference for the excavation of shallow buried multi pilot tunnel with tunnel pile-beam-arch approach.

Published: July 2022

Abstract
Lightness of a surface depends not only on its physical characteristics, but also on the properties of the surrounding context. As a result, varying the context can significantly alter surface lightness, an effect exploited in many lightness illusions. Computational models can produce outcomes similar to human illusory percepts, allowing for demonstrable assessment of the applied mechanisms and principles. We tested 8 computational models on 13 typical displays used in lightness research (11 Illusions and 2 Mondrians), and compared them with results from human participants (N = 85). Results show that HighPass and MiR models predict empirical results for simultaneous lightness contrast (SLC) and its close variations. ODOG and its newer variants (ODOG-2 and L-ODOG) in addition to SLC displays were able to predict effect of White’s illusion. RETINEX was able to predict effects of both SLC displays and Dungeon illusion. Dynamic decorrelation model was able to predict obtained effects for all tested stimuli except two SLC variations. Finally, FL-ODOG model was best at simulating human data, as it was able to predict empirical results for all displays, bar the Reversed contrast illusion. Finally, most models underperform on the Mondrian displays that represent most natural stimuli for the human visual system.

Abstract
Regulation services are the benefits for human well-being obtained from the performance of ecosystems, for instance in terms of carbon sequestration, nitrogen fixation or weed control. The aim of the presented study was to evaluate regulating ecosystem services and their dependency on the genetic diversity of the faba bean as a key staple food in Near East and Central Asia. For this purpose, we carried out an experiment in the form of randomized complete blocks design at Gorgan University of Agricultural Sciences and Natural Resources (Gorgan, Golestan province), Iran, during 2019–2020. In this experiment, genetic diversity of faba bean and its impact on selected regulating services was evaluated through cultivation of five genetic varieties of this plant. Studied varieties were selected from three grain groups (fine, medium and coarse). We included eco-physiological indicators in our study such as soil microbial respiration rate, weed control and nitrogen biofixation potential. The results showed that the provision of some services such as soil carbon sequestration, nitrogen biofixation potential, soil microbial respiration and weed control depend on genetic diversity of the faba bean. New faba bean varieties can better compete with weeds through their production of massive foliage and their growth form. Based on the obtained results, we elaborated on recommendations for how faba bean cultivation can contribute to an increase in the soil microbial respiration rate and carbon sequestration. We found that especially the medium grain variety of faba bean increased the capacity to provide regulating ecosystem services.
Histology and morphometry of the skin of the trident goby Tridentiger brevispinis (Perciformes, Gobiidae)
Authors: Kim Hyun-Tae 
Published: July 2022

Abstract
The Korean trident goby, Tridentiger brevispinis, lives in adverse habitats that can easily become hypoxic due to low precipitation, regional dry periods, and high amounts of solar radiation. Histological and morphometric studies revealed the goby’s specialized skin (35.4–150.0 µm in thickness), consisting of an epidermis and dermis. The thicker epidermis comprises an outermost surface layer (having taste buds, stratified flattened cells, mucous cells, pigment cells, and stratified polygonal cells), middle layer (having stratified polygonal cells), and stratum germinativum (stratified columnar cells). In particular, the dermis has scales, well-developed vascularization, and a few blood capillaries just above the basement membrane, and a reduced diffusion distance was present in the lateral body. Consequently, adaptations such as thicker epidermis, well-developed vascularization, few blood capillaries, and a reduced diffusion distance may provide cutaneous respiration for survival in poorly oxygenated water during the periodic dry season.

Abstract
Cotton is one of the most important natural raw materials in the textile industry. Due to its cotton structure, it has always been preferred by users in terms of both natural and comfortable properties., Cotton despite the decrease in its share in the textile fibre market, continues to be the main natural fibre used in textiles. However, variations in cotton spinning caused by raw materials, decrease yarn production performances and leads to serious productivity losses. Generally, in purchasing cotton with HVI tests, production programs are carried out taking into account criteria such as maturity index, strength, fibre length, fineness, colour, humidity, neps and amount of foreign matter. Nevertheless, except for HVI tests performed as standard, the sugar test performed on cotton is a process that is carried out with random controls that are specially measured when purchasing raw materials and cannot be controlled in each bale.The main reason for the stickiness problem, which causes great problems in yarn production Stickiness rate (sugar amount), is cotton bales that go into production out of high control. Stickiness is observed in cotton; felting on the combs in the yarn line, surrounding the cylinder in the roving frame, sticking to the apron in the ring-spinning machine and causing a decrease in yarn quality. Despite the technological developments, today's yarn spinning machines have not been able to produce an effective solution to the stickiness problem caused by raw materials.In this study, to improve innovative solutions to the problem of stickiness experienced in cotton, a comprehensive study was conducted on sugar testing methods in cotton, and some improvement studies were carried out. For this, 3 cotton mixtures with different sugar ratios were used. 12 Different 30/1 Combed Compact yarns were produced from these mixtures by the experimental plan. In these yarn productions, process studies were carried out with berkolization process and climate conditioning steps on sleeve surface gradually at the enterprise, the percentage of stickiness to the cots, the breakage rate in coil cutting, and the amount of stickiness, and the Uster test results were significantly examined.

Abstract
The study investigated adaptation strategies employed by farming households to insecurity in Southwest Nigeria. 50 farming households were selected through a multi-staged sampling technique. Data were gathered through interview schedules, described with frequencies, percentages and mean; and presented in tables and figures. Chi-square test of independence was used to check for statistical significance between dependent and independent variables. Results revealed that the mean age of the respondents was 41 years, while 58% were females. Seventy six percent of sampled farming households often witnessed attacks by Fulani herdsmen. These incessant attacks majorly affected the health and economic assets of the respondents. There were less extension visits in communities affected by insecurity. Of the adaptation strategies, majority of them erect high gates and fences to prevent further attacks. Based on the result from the Chi-square test, selected socio-economic characteristics of farmers had a positive influence on adaptation strategies used. It is therefore recommended that extension agents need to intensify the use of social media since physical contact seems challenging in the face of insecurity. Government and private organizations should set up and equip local security outfits in rural areas to stop frequent attacks by herdsmen.

Published: July 2022

Abstract
In the areas declared to be a tourism center, a rapid tourism-related development occurs depending on the investments in tourism, which causes a dramatic land use and land cover changes. Determining, monitoring, and modeling of land use and land cover changes are required in order to ensure the conservation-use balance and sustainability within such vulnerable areas that are under the development pressure. This study consists of four steps. In the first step, the Landsat images dated 1985, 2000, and 2021 were classified using the maximum likelihood method and the land use and land cover of Belek Tourism Center located in Turkey were determined. The second step included the identification of areal and spatial changes between the land use and land cover classes for the periods between 1985 and 2000, 2000 and 2021, and 1985 and 2021. In the third step, the land use and land cover changes in Belek Tourism Center for 2040 were modeled using the Land Change Modeler. Last step evaluated the relationship between the modeled spatial development pattern and the current planning decisions. According to the results obtained through a 36-year research, the rates of settlement, forest, and water body areas have increased by 11.91%, 13.67%, and 0.82%, respectively whereas the rates of barren land and agricultural areas have reduced by 22.25% and 4.15%, respectively. The land use map modeled for 2040 predicts the settlement areas to expand by 5.46% and the agricultural areas to shrink by 4.21% by comparison with 2021.

Abstract
BackgroundStrong governance and regulatory supervision are required to conduct research in an emergency context and ensure compliance with ethical standards. Preparedness and response rely on the formalization, structure, and function of national research ethics systems. The Strengthening research ethics governance and regulatory oversight in Central America and the Dominican Republic in response to the COVID-19 pandemic (GoEtiCA) study is a regional effort addressing research ethics governance challenges during the pandemic. This study describes the ethics governance that addresses specific humanitarian and health challenges caused by COVID-19; it also analyzes the regulatory oversight of research, and preparedness response to the pandemic in Central America and the Dominican Republic. The study aimed to inform the development of a policy brief to advancing international ethical standards adoption. MethodsA qualitative study was conducted following a participatory approach. Research ethics stakeholders in Central America and the Dominican Republic were mapped; a regional webinar and three virtual workshops were conducted discussing research governance, ethics review, and collaborative practices during the pandemic. A roundtable session presented results and obtained feedback on a draft of a policy to strengthen regional research ethics governance. ResultsCountries across Central America and the Dominican Republic are at different stages in their development of governance structures and regulations for research ethics systems. Countries that had more established systems before COVID-19, were better organized and prepared to respond. This finding argues against improvisation and supports further work on research ethics systems. Strong international scientific cooperation and collaborative practices are lacking within and amongst the countries. Collaborative structures and practices for research, community engagement in policymaking, and ethics review are scarce; however, there are incipient initiatives, including the Central America Network of Research Ethics Committees. ConclusionNational and regional research ethics governance structures in Central America and the Dominican Republic were not prepared to respond to the COVID-19 pandemic with research oversight and effective collaboration. In most cases, national research ethics governance structures are weak and regional research collaboration is ineffective. To promote collaboration, efforts that identify implementation gaps and share knowledge and best practices are needed.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative condition marked by memory loss and dementia, caused by changes in the cortical milieu, such as neuroinflammation, oxidative stress, and accumulation of beta-amyloid (Aβ) in the brain. The drug-induced cognitive impairment is more common in the elderly than in younger people. The research-using valid animal models may help determine the effective and safe medicine for AD treatment. Studies have found that patients who used lansoprazole for long-term therapy for ulcers, Zollinger-Ellison syndrome, and gastroesophageal reflux disease (GERD) who may suffer from memory problems. The novel research was designed to check whether lansoprazole administration to rats may enhance oxidative stress, Aβ accumulation and neurodegeneration. In the current study, rats were given lansoprazole at doses of 15 and 30 mg/kg p.o. for 28 days. The Morris water maze and Probe trial were used to assess rats spatial and recognition memory deficits. On day 29, the rats were sacrificed, and the brain (hippocampus) was used to test for biochemicals (glutathione, superoxide dismutase, catalase, lipid peroxidation, and nitrite), neuroinflammatory markers (IL-1β, TNF-α & IL-6) neurotransmitters (ACh, GABA, and Glutamate), Aβ(1–42) level, nuclear factor-kappa B (NF-κB) analysis, and blood-brain barrier (BBB) disruption activity. Lansoprazole administrated raised inflammatory cytokines release, oxidative stress, altered neurotransmitter concentration, tau protein phosphorylation, and promoted the Aβ accumulation in the brain. These findings showed that lansoprazole treatment for four weeks caused neurobiological alteration in rats and degeneration of the endogenous antioxidant defense system.
