Authors:   Satbayev University, DURMAGAMBETOV B. , URMANOVA D. ,   Satbayev University
Published: January 2023

This article analyzes complex laboratory and simulation studies of salt deposition during oil production in conditions of low permeability with falling reservoir pressure. The object of research is Jurassic deposits of horizons with a depth of up to 3000 m. The study of salt formation problems pursues the following objectives: to determine the type of salts (within and using the resources available for research), to conduct modeling to understand longterm trends in salt formation (during water injection projects) or short-term trends (during hydraulic fracturing or cattle), as well as to make recommendations based on tests and the Schlumberger database. The formation waters of the Jurassic deposition of the field have similar hydrochemical parameters along the horizons and are chlorocalcium brines, the total mineralization of which ranges from 147.1 g/l to 186.6 g/l. According to the available data, there is no clear dependence of mineralization on the depth of occurrence. The density in surface conditions is 1097-1131 kg/m3. In terms of concentration, chlorides predominate over alkali metals (sodium, potassium), and the waters are also noticeably enriched with calcium, the content of which significantly prevails over magnesium. A characteristic feature is the low content of sulfate and bicarbonate ions. The research and scientific nature of this work is confirmed by the fact that a new scientific software for the analysis of salt deposition was used for the Kazakhstani industry of intensification of hydrocarbon production. Modeling of critical thermobaric points covers the range of predicted parameters of reservoir pressure and temperature, as well as the resulting temperature in the bottomhole zone, taking into account the operation of the installation of an electric centrifugal pump. The sensitivity analysis was carried out taking into account the percentage ratio of injected and reservoir water, the parameters of the water used during hydraulic fracturing were calculated separately. The result of the study is a quantitative assessment of the permeability from salt deposition and preventive measures to preserve the productivity coefficient of wells.

A steady increase in the water content of the extracted oil, an increase in the volume of heavy grades of oil with stable emulsions, an increase in the proportion of thick oil in the total volume of refined oil due to the imperfection of the oil dewatering process is far from a complete list of factors determining the importance and relevance of the issue of optimal automatic control of the oil dewatering process in the fields today. Although this problem is not new to the oil industry, its solution is not yet completed. This circumstance is due to insufficient knowledge of the processes of oil preparation due to the emerging objective difficulties and the lack of adequate models that could be used to solve the problems of stabilization and optimization of the oil dewatering process. The paper presents the research on the process of breaking highly-stable heavy oil emulsions by water evaporation. An equation has been derived and relevant curves have been plotted to calculate the required heating temperature. This study shows the dependence of hydrocarbon distillate yield on heating temperature, boiling point oil composition and the initial water cut of the emulsion. The technology of oil dehydration from the field has been tested.

Published: January 2023

The study has been aimed to know the impact of Employee Empowerment on CI of health care between hospitals (government and private). The required data for the purpose of this study were collected by a questionnaire designed on the basis of related practices. It consisted of 73 items divided into two domains, the first one to measure employee empowerment practices (37 items), and the second one to measure CI practices (36 items). The study sample was applied to the (326) respondents; The total number of respondents from hospitals was 326; That is, 76% of the total number of the target group, which is (431) respondents, with a response rate of 96%, which is high percent because the researcher distributed the questionnaires personally. Using IBM SPSS and a comparative descriptive-analytical approach. Three themes emerged from the respondents’ trends. First, the existence of employee empowerment application in government hospitals was moderately level, and in private hospitals was in a high level, and also the existence of CI application in government hospitals was in a low level, and in private hospitals was in a high level. Second, there is a strong correlation between employee empowerment and CI of health care in hospitals (government, private). Third, there is statistically significant impact at the level (α ≤ 0.05) of the Employee empowerment on CI of health care whether the dimensions of CI are combined or fragmented in hospitals. The limitation of this study was in fixed bureaucracy structure in governmental hospitals and competitiveness issues in private hospitals. The study dealt with a dependent variable that was rarely studied by previous Arab studies and also rarely comparative study between profit and nonprofit hospitals.

Published: January 2023

In this study, the $ (h $-$ \varphi)_R $ and $ (h $-$ \varphi)_M $-contractions with two metrics endowed with a directed graph are examined using auxiliary functions. We propose a set of criteria that guarantees the existence of common fixed points for our contractions. This leads to a generalization of previous results in the literature. Towards our accomplishments, we establish affirmative results that demonstrate solutions to a class of nonlinear two-term fractional differential equations with nonlocal boundary conditions. To further corroborate our major findings, we also provide instances.
Some new versions of Jensen, Schur and Hermite-Hadamard type inequalities for $ \left({p}, \mathfrak{J}\right) $-convex fuzzy-interval-valued functions

Published: January 2023

To create various kinds of inequalities, the idea of convexity is essential. Convexity and integral inequality hence have a significant link. This study's goals are to introduce a new class of generalized convex fuzzy-interval-valued functions (convex 𝘍𝘐𝘝𝘍s) which are known as $ \left(\mathfrak{p}, \mathfrak{J}\right) $-convex 𝘍𝘐𝘝𝘍s and to establish Jensen, Schur and Hermite-Hadamard type inequalities for $ \left(\mathfrak{p}, \mathfrak{J}\right) $-convex 𝘍𝘐𝘝𝘍s using fuzzy order relation. The Kulisch-Miranker order relation, which is based on interval space, is used to define this fuzzy order relation level-wise. Additionally, we have demonstrated that, as special examples, our conclusions encompass a sizable class of both new and well-known inequalities for $ \left(\mathfrak{p}, \mathfrak{J}\right) $-convex 𝘍𝘐𝘝𝘍s. We offer helpful examples that demonstrate the theory created in this study's application. These findings and various methods might point the way in new directions for modeling, interval-valued functions and fuzzy optimization issues.
SLeNN-ELM: A shifted Legendre neural network method for fractional delay differential equations based on extreme learning machine
Authors: Ye Yinlin , Li Yajing , Fan Hongtao , Liu Xinyi , Zhang Hongbing
Published: January 2023

In this paper, we introduce a shifted Legendre neural network method based on an extreme learning machine algorithm (SLeNN-ELM) to solve fractional differential equations with constant and proportional delays. Based on the properties of Caputo fractional derivatives and shifted Legendre polynomials, the fractional derivatives of SLeNN can be represented analytically without other numerical techniques. SLeNN, in terms of neural network architecture, uses a function expansion block to replace the hidden layer, and thus improving the computational efficiency by reducing parameters. In terms of solving technology of neural networks, the extreme learning machine algorithm is used to replace the traditional gradient-based training algorithm. It dramatically improves our solution efficiency. In addition, the proposed method does not require parameter initialization randomly, making the neural network solution stable. Finally, three examples with constant delays and three examples with proportional delays are given, and the effectiveness and superiority of the proposed method are verified by comparison with other numerical methods.
A Small Warm Tributary Provides Prespawning Resources for Colorado Pikeminnow in a Cold Dam-Regulated River
Authors: Kluender Edward R. , Bestgen Kevin R.
Published: January 2023

Riverine habitat mosaics, including tributaries, are an important reason the Green River subbasin supports the largest remaining population of federally endangered Colorado Pikeminnow Ptychocheilus lucius in the Colorado River Basin. Upstream Colorado Pikeminnow distribution is limited by Flaming Gorge Dam and few typically occurred in the reach immediately downstream of the dam, which is the reach most affected by thermal and hydrologic alterations. However, fish captures and passive integrated transponder (PIT) antenna sampling of previously tagged individuals from 2011 to 2021 revealed seasonal congregations of up to 75 Colorado Pikeminnow annually in the mouth of Vermillion Creek, a small tributary in the regulated reach. Approximately 11% (N = 93 individuals) of the entire 2017–2018 Green River basin population were encountered in Vermillion Creek over the 11-y study, an underestimate of use considering that untagged fish were not detected by antennas. Colorado Pikeminnow used Vermillion Creek primarily when Green River spring flows from Flaming Gorge Dam were high and cold in May through mid-June when the confluence was a large, deep backwater warmer than the main channel and supported forage fishes. Intra-annual encounters revealed seasonal residence times for individual Colorado Pikeminnow up to 91 d, and multiple inter-annual encounters indicated site fidelity. Frequent detections of individual Colorado Pikeminnow in a Yampa River spawning area soon after their detections in Vermillion Creek indicate this tributary may be an important resource for reproductive adults. The intensive and basin-wide PIT tagging and detection program for Colorado Pikeminnow enhanced our understanding of the importance of small habitat nodes such as Vermillion Creek in the Green River drainage network. Understanding and protecting these seasonally available riverine habitat mosaics used for prespawning conditioning may assist with recovery of Colorado Pikeminnow.
Nudging Towards Sustainable Public Transportation
Authors: Manfreda Anton , Erjavec Jure
Published: January 2023

The chapter presents the importance of public transportation in coping with contemporary environmental issues. However, the aim is not to present public transportation as the only method of transportation leading towards a green future. New services and solutions should be carefully developed in cooperation with residents considering their needs, culture, habits, and existing procedures. Transforming the mindset of residents should be considered as well. Therefore, the authors present the readers with different theories, models, tools, and frameworks, illustrated with existing cases for promoting behavioral change amongst individuals, focusing specifically on nudging mechanisms. While the focus of the chapter is mainly on nudging towards sustainable public transportation, the authors illustrate nudging with examples from other areas as well and argue how such uses can also be applied to promote sustainable public transportation. This chapter is therefore aimed at policymakers and other stakeholders involved in promoting sustainable public transportation modes.
Intermediate Levels of Pre-Existing Protective Antibody Allow Priming of Protective T Cell Immunity against Influenza

Published: January 2023

Overcoming interfering impacts of pre-existing immunity to generate universally protective influenza A virus (IAV)-specific T cell immunity through vaccination is a high priority. In this study, we passively transfer varied amounts of H1N1-IAV–specific immune serum before H1N1-IAV infection to determine how different levels of pre-existing Ab influence the generation and protective potential of heterosubtypic T cell responses in a murine model. Surprisingly, IAV nucleoprotein-specific CD4 and CD8 T cell responses are readily detected in infected recipients of IAV-specific immune serum regardless of the amount transferred. When compared with responses in control groups and recipients of low and intermediate levels of convalescent serum, nucleoprotein-specific T cell responses in recipients of high levels of IAV-specific serum, which prevent overt weight loss and reduce peak viral titers in the lungs, are, however, markedly reduced. Although detectable at priming, this response recalls poorly and is unable to mediate protection against a lethal heterotypic (H3N2) virus challenge at later memory time points. A similar failure to generate protective heterosubtypic T cell immunity during IAV priming is seen in offspring of IAV-primed mothers that naturally receive high titers of IAV-specific Ab through maternal transfer. Our findings support that priming of protective heterosubtypic T cell responses can occur in the presence of intermediate levels of pre-existing Ab. These results have high relevance to vaccine approaches aiming to incorporate and evaluate cellular and humoral immunity towards IAV and other viral pathogens against which T cells can protect against variants escaping Ab-mediated protection.
The m6A Reader YTHDF2 Modulates Antiviral and Antibacterial Activity by Suppressing METTL3 Methylation-Modified STING in Fish
Authors: Geng Shang , Zheng Weiwei , Wang Wansu , Lv Xing , Xin Shiying , Xu Tianjun
Published: January 2023

At present, N6-methyladenosine (m6A) modification has been proven to participate in a wide range of gene expression regulation, such as stability, translation, splicing, and output, among others, which has attracted much attention. Unlike mammals, however, the role of m6A in innate immunity of lower invertebrates has not yet been studied. In this study, we found that the total m6A level of Miichthys miiuy increased during Siniperca chuatsi rhabdovirus and Vibrio anguillarum infection, suggesting that m6A may play an important role in the immune process against pathogens in fish. In addition, our study shows that stimulator of IFN genes (STING) plays a dual immune function against viruses and bacteria in fish, and through degrading STING by identifying its m6A methylation site modified by methyltransferase-like 3 (METTL3), YTH domain family 2 (YTHDF2) can weaken the IRF3 and NF-κB–driven signaling pathway, thus weakening the innate immunity and promoting the infection of Siniperca chuatsi rhabdovirus and V. anguillarum to the M. miiuy. Although there have been reports on m6A modification of STING in mammals, it is still unclear whether there is also m6A modification in lower vertebrates, especially in fish. Therefore, our study provides a reference for filling the gap of m6A modification between fish and mammals.

Authors: Peek Kerry , Versteegh Theodore , Veith Stella , Whalan Matt , Edwards Suzi , McKay Marnee , Gardner Andrew John
Published: January 2023

Context

Concern is growing among soccer players, coaches, and parents regarding head and neck injuries, including concussion, particularly from heading a ball. Thus, we need to explore soccer-specific head injury risk-reduction initiatives. One such initiative is to condition the neck musculature of young players by adding neuromuscular neck exercises to existing injury-reduction exercise programs.

Objective

To investigate the effect of neuromuscular neck exercises completed as part of an injury risk-reduction exercise program on the incidence of soccer-related head and neck injuries in adolescent soccer players.

Design

Prospective cohort study.

Setting

Two sports high schools and 6 soccer clubs during the 2021 soccer season.

Patients or Other Participants

A total of 364 male and female soccer players, aged 12 to 18 years.

Intervention(s)

Members of 1 sports high school and 2 soccer clubs performed neuromuscular neck exercises as part of an injury-reduction program during training (neck training group). Members of another sports high school and 4 soccer clubs performed an injury-reduction program but without neck exercises (comparison group).

Main Outcome Measure(s)

Self-reported injury data were collected from each player at the end of the season and used to calculate incidence rate ratios (IRRs) with 95% CIs.

Results

In total, 364 players completed the study, including 146 players in the neck training group and 218 players in the comparison group. Despite players in the neck training group being less likely to self-report a concussion (IRR = 0.23; 95% CI = 0.03, 1.04) and pain on heading a ball (IRR = 0.62; 95% CI = 0.34, 1.07), only a lower incidence of possible concussive events (IRR = 0.38; 95% CI = 0.14, 0.90; P < .05) was significant.

Conclusions

Integrating neuromuscular neck exercises into injury-reduction exercise programs has the potential to reduce the risk of adolescent soccer players sustaining a possible concussive event, concussion, or pain on heading a ball.
The Role of Integrated Approach to Yoga Therapy-Based Yoga Module in Improving Cardiovascular Functions and Lipid Profile in Hypertensive Patients
Authors: Shetty Shivaprasad , Nandeesh NS , Shetty Prashanth
Published: January 2023

Background:

Hypertension is a growing public health problem and its optimal management is imperative. Integration of lifestyle modification and yoga with antihypertensive drugs leads to its successful management. Yoga has been shown to modulate blood pressure (BP) and lipid metabolism in individuals with hypertension. The current study is a preliminary effort to ascertain the underlying mechanisms behind it.

Materials and Methods:

Hundred patients were screened, among which 65 who met the inclusion criteria were recruited. After baseline assessments, they were randomly allocated (1:1) to an intervention group (IG) who practiced integrated approach to yoga therapy (IAYT)-based yoga module for 6 days a week, for 3 months and a control group (CG) who received no intervention. BP, heart rate variability, and lipid profile were assessed before and after the intervention. Data acquired from 60 cases were analyzed by post-hoc analysis for multiple comparisons between the mean values.

Results:

At the end of 3 months, within-group comparison showed significant changes (P < 0.05) in IG in all variables except triglycerides, high-density lipoprotein (HDL), and very low-density lipoprotein (LDL) while similar changes were not present in the control group. Significant differences were seen between the groups in the TC (P = 0.005), HDL (P = 0.047), non-HDL (P = 0.013), LDL (P < 0.001), LDL/HDL Ratio (P = 0.031), CHOL/HDL Ratio (P = 0.043), DBP (P < 0.001), SBP (P < 0.001), and all indices of HRV (P < 0.001).

Conclusion:

These findings suggest that IAYT-based yoga module was effective in improving cardiovascular performance and lipid metabolism, thereby mitigating coronary artery disease risk.

Published: January 2023

Meditation is a practice of concentration and relaxation. In philosophical terms, it is a process of gaining self-consciousness. Although there is diversity in meditation (Mindfulness, compassion, transcendental, and focused attention meditation), interventions show that meditation practices improve prefrontal cortex (PFC) functions like cognition, self-awareness, attention, and memory and reduce psychological symptoms. These results are thought to be due to meditation increasing functional connections of different brain regions. We reviewed to show the functional connectivity of the prefrontal cortex in various meditation practices. We were viewed various neuroimaging interventions of functional connectivity associated with the prefrontal cortex and different brain areas during meditation techniques on healthy meditators compared with non-meditators. fMRI findings show that meditation practices are associated with increased neural function and processing, default mode network, gray matter volume, and functional coupling in the brain area related to different parts of PFC. PFC's functional connectivity is associated with increased attention, working memory, cognitive control, executive control, emotion regulation, counteracting adverse effects, self-perception, and self-compassion. Furthermore, PFC's functional connectivity decreases anxiety, depression, perceived stress, negative emotion, and hyperarousal symptoms. In this review, we outlined the published effect of meditation on the function and structure of the different parts of the prefrontal cortex. We suggest a positive theoretical correlation between meditation and the functional connectivity of the prefrontal cortex. Altered prefrontal connectivity is seen in some neurological and psychosocial disorders. Therefore meditation can also play an influential role in treating these disorders.

Context:

COVID-19-affected patients showed increased stress, impaired sleep quality, altered complete blood count, and increased inflammatory and oxidative parameters. Yoga is an add-on nonpharmacological treatment that is established to normalize the abovementioned parameters. Heartfulness meditation is a form of Raja yoga.

Aims:

The present study aimed to study the effects of 4 weeks of heartfulness meditation on the abovementioned parameters in COVID-19 patients following treatment completion.

Settings and Design:

The present study was a randomized controlled trial carried out in the Department of Physiology, AIIMS, Mangalagiri, Andhra Pradesh.

Subjects and Methods:

Out of 50 COVID-19 treatment-completed patients recruited for the study, 25 were randomly assigned to the study group who received 4-week app-based heartfulness meditation. Other 25 patients were assigned to the control group who received app-based relaxation for 4 weeks. Perceived stress score, Pittsburgh Sleep Quality Index questionnaire, baseline cardiovascular parameters, complete blood count, serum cortisol, inflammatory parameters, oxidative stress parameters, and antioxidant parameters were assessed before and after 4 weeks of intervention in both the groups. The outcome assessor was blinded in the present study.

Statistical Analysis Used:

The mean difference between the two groups was tested using the Student's t-test or Mann–Whitney U-test based on data distribution. Effect of intervention was analyzed using paired Student's t-test for dependent samples test or Wilcoxon signed-rank test based on data distribution.

Results:

The groups were comparable before intervention for all the variables. After 4 weeks of intervention, we observed a significant decrease in stress, circulating cortisol, inflammatory markers, and oxidative stress biomarker in both the groups. Further, we observed improved sleep quality and antioxidant biomarkers in both the groups. These beneficial alterations following intervention were high in the study group compared to the control group.

Conclusions:

Our results suggest that app-based heartfulness meditation/relaxation can be used as a nonpharmacological adjuvant to hasten the recovery process in patients who have completed the COVID-19 treatment protocol. Beneficial effects in subjects practicing heartfulness meditation were more than that observed in subjects practicing relaxation.
Ayurvedic Intervention and COVID-19

Published: January 2023

Ayurveda focuses on the diet, lifestyle, herbal medicines, and herbo-mineral medicines as per the specific constitution (Prakriti) of an individual. In this COVID-pandemic, various healthcare systems dynamically respond to combat the disease. Ayurveda also has evidence on case studies and case reports treated through Ayurvedic intervention. Therefore, there is a need for systematic review of all studies of COVID-19 and Ayurvedic intervention. The aim of this study was to systematically review the available case studies and case reports on Ayurvedic formulations/interventions in COVID-19. The published data were retrieved from MEDLINE, Embase, Science Direct, Scopus, Web of Science, Google Scholar, MedRxiv, and OSF on July 1, 2021. The search did not include any restrictions. Case reports and case studies published for COVID-19 through Ayurvedic formulation/intervention. Standard method for data extraction and coding was developed for the analysis of the eligible case studies and case reports. A total of 59 studies were collected from different databases; among them, extractions were made for repetitive studies; after extraction, only 17 studies were taken. The present systematic review proves that Ayurveda science is safe and effective without an adverse effect in treating COVID-19 even in high-risk, comorbid, vulnerable conditions. Adaptation of Ayurveda in the COVID-19 pandemic is the positive hope for the management of COVID-19.

ABSTRACT

Aim and Objectives:

The study was conducted to to compare the dosimetric superiority between the Field in Field and Box techniques.

Meterials and Methods:

We have taken 22 Patients of Ca esophagus for our study from our Institute database. Patients were already treated Box (4 fields) plan. Retrospectively additional Field in Field (FIF) plan was created with Planning target volume (PTV) prescription dose of 59.4Gy in 33 fractions. Prescription dose of 95% of PTV was chosen for the comparison between two treatment planning strategies. The Dose volume histogram (DVH) was used to analyze and compare various plan quality index and doses to the organs at risk (OARs). For each patient, two treatment plans were created: Box 4FB and FIF. The parameters compared included the conformity index (CI), homogeneity index (HI), Conformation number (CN), DMean, DMax, V20Gy and V30Gy of the heart and lungs, and monitor units per fraction (MU/fr).

Results:

A paired t-test analysis significant differences (P < 0.05) between the two techniques in terms of the CI, HI, and CN when the FIF was applied. The Dmax of the PTV, lung, and spinal cord were also significantly better with the FIF. Moreover, the V20Gy of the significantly reduced when the FIF was used and the MU/fr was significantly decreased. The FIF technique enables better dose distribution in the PTV and reduces dose to OARs in esophageal radiotherapy.

Conclusion:

Although all plans were within acceptable limits, dosimetric comparison of different planning techniques revealed that FIF had statistically significant differences from Box planning technique in terms of planned target volume (PTV) coverage, OAR protection, HI, CI, CN, MU and treatment duration. From the aspect of treatment duration and MU parameters, FIF technique can be considered as an alternative planning option.
Projective freeness and stable rank of algebras of complex-valued BV functions
Authors: Brudnyi Alexander
Published: January 2023

The paper investigates the algebraic properties of weakly inverse-closed complex Banach function algebras generated by functions of bounded variation on a finite interval. It is proved that such algebras have Bass stable rank 1 and are projective-free if they do not contain nontrivial idempotents. These properties are derived from a new result on the vanishing of the second Čech cohomology group of the polynomially convex hull of a continuum of a finite linear measure described by the classical H. Alexander theorem.
Invariant means on weakly almost periodic functionals with application to quantum groups

Published: January 2023

Let
${\mathcal A}$
be a Banach algebra, and let
$\varphi $
be a nonzero character on
${\mathcal A}$
. For a closed ideal I of
${\mathcal A}$
with
$I\not \subseteq \ker \varphi $
such that I has a bounded approximate identity, we show that
$\operatorname {WAP}(\mathcal {A})$
, the space of weakly almost periodic functionals on
${\mathcal A}$
, admits a right (left) invariant
$\varphi $
-mean if and only if
$\operatorname {WAP}(I)$
admits a right (left) invariant
$\varphi |_I$
-mean. This generalizes a result due to Neufang for the group algebra
$L^1(G)$
as an ideal in the measure algebra
$M(G)$
, for a locally compact group G. Then we apply this result to the quantum group algebra
$L^1({\mathbb G})$
of a locally compact quantum group
${\mathbb G}$
. Finally, we study the existence of left and right invariant
$1$
-means on
$ \operatorname {WAP}(\mathcal {T}_{\triangleright }({\mathbb G}))$

The first manifestation of a viral infection may be conjunctivitis. There are limited data on the etiology of viral conjunctivitis in Vanuatu, a country in the South Pacific Ocean. Patients presenting to one of two Vanuatu health centers with presumed infectious conjunctivitis were eligible if symptom onset was within 14 days of screening. Conjunctival and anterior nasal swabs were obtained and subjected to unbiased RNA deep sequencing (RNA-seq) to identify DNA and RNA viruses. For samples collected from May to November 2021, RNA-seq identified a viral etiology in 12/48 patients. Human adenovirus species were the most common viruses (58%) detected, followed by human herpes viruses (cytomegalovirus, varicella zoster virus, and human herpes 7 virus). Rhinovirus C, Epstein-Barr virus, and bocavirus were also detected. In summary, the etiology for viral conjunctivitis in Vanuatu appears broad. Unbiased testing may be useful for disease surveillance.
