Published: July 2021

Background

Exposure to occupational stressors and potentially psychologically traumatic events experienced by public safety personnel (eg, paramedics, police, fire, and correctional officers), military members, and veterans can lead to the development of posttraumatic stress injuries and other mental health disorders. Providing emergency services during COVID-19 has intensified the challenges. Owing to COVID-19 restrictions, mental health service providers offering support to these populations have had to rapidly pivot to use digital versus in-person methods of service delivery.

Objective

This paper aims to explore the experience of mental health service providers regarding digital health service delivery, including the current state of digital mental health service delivery, barriers to and facilitators of the use of digital health for mental health service delivery experienced during the pandemic, and recommendations for implementing and integrating digital health into regular mental health service delivery.

Methods

This embedded mixed-methods study included questionnaires and focus groups with key stakeholders (N=31) with knowledge and experience in providing mental health services. Data analysis included descriptive, quantitative, and qualitative thematic analyses.

Results

The following three themes emerged: being forced into change, daring to deliver mental health services using digital health, and future possibilities offered by digital health. In each theme, participants’ responses reflected their perceptions of service providers, organizations, and clients. The findings offer considerations regarding for whom and at what point in treatment digital health delivery is appropriate; recommendations for training, support, resources, and guidelines for digitally delivering trauma therapy; and a better understanding of factors influencing mental health service providers’ perceptions and acceptance of digital health for mental health service delivery.

Conclusions

The results indicate the implementation of digital health for mental health service delivery to military members, public safety personnel, and veterans. As the COVID-19 pandemic continues, remote service delivery methods for trauma therapy are urgently needed to support the well-being of those who have served and continue to serve.

Authors: Mani Ece , Kirmizigil Berkiye , Tüzün Emine Handan
Published: July 2021

Aim:
This study aimed to compare the immediate and long-term effect of proprioceptive neuromuscular facilitation (PNF) contract–relax–antagonist–contract (CRAC) exercises versus static stretching on proprioception and flexibility in males with hamstring shortness.
Patients & methods:
Knee extension angle test was used to measure flexibility and isokinetic dynamometer to evaluate proprioception. Assessments were evaluated at baseline, after first exercise and eighth week. The hamstring stretching was applied 3 days a week for 8 weeks.
Results:
Flexibility and position sense were similar in the immediate and long term (p > 0.05). However, the motion sense increased significantly in long term within the PNF CRAC group (p = 0.02).
Conclusion:
Both stretching exercises are effective for improving flexibility. Moreover, PNF CRAC improved motion sense more than static stretching in the long term.

Authors: Hernández-Hernández Oscar Misael
Published: July 2021

El objetivo de este artículo es analizar cómo algunas organizaciones gubernamentales y no gubernamentales atendieron a migrantes durante el inicio de la pandemia por Covid-19 en la frontera de Tamaulipas, al noreste de México. Teóricamente se apropian los conceptos de política pública y acción pública. El primero entendido como el trabajo o la intervención de autoridades gubernamentales para atender problemas sociales, y el segundo como la identificación de problemas colectivos y la elaboración de respuestas por parte de actores específicos de la sociedad. Metodológicamente, se realizaron entrevistas telefónicas a algunos coordinadores de albergues para migrantes, se seleccionaron y analizaron notas periodísticas, así como reportes sobre el tema. Se encuentra que las autoridades gubernamentales implementaron algunas políticas de atención a migrantes y las organizaciones no gubernamentales algunas acciones de apoyo hacia esta población para prevenir contagios. Incluso, se identifica que tanto las primeras como las segundas construyeron sinergias, aunque en algunos casos emergieron conflictos debido a los recursos e intereses diferenciados para atender a los migrantes ante el Covid-19.

The aim of the study was the need to theoretically and experimentally substantiate the technology of diagnostics and correction of maladjustment changes in the psychoemotional sphere of seafarers at the stages of a long voyage. Materials and methods. The material of the research is dynamic observation in the form of psychological testing, carried out during a long voyage of the crew (n = 48 people) of the BMRT fishing vessel (large freezer fishing trawler) with the home port of Murmansk. The age of the fishermen varied from 22–36 years and averaged 27.0±0.84 years, the duration of the cruise was 152 days to catch fish in the Southwest Atlantic. The subjects belonged to different professional groups, and had worked at sea from 3 to 11 years (M = 5.4±0.26). The research methods were valid methods applied in a complex: a modified eight-color test by M. Luscher, personality questionnaire “EPI” by G. Aysenk, psychodiagnostic test “General assessment of personality” by V.М. Melnikov and L.T. Yampolsky, the MMPI questionnaire «Personal scale of manifestations of anxiety, the questionnaire» Life style index «(«LSI») Kellerman-Plutchik-Conte for identifying types of psychological defenses, the test for the study of reactive and personal anxiety Spielberger-Khanin and the test card SAN (test questionnaire Mini-cartoon). Results and discussion. the study showed that continuous (more than 3 months) fishing in the sea leads to changes in the psycho-emotional sphere of fishermen, manifested in the appearance of signs of psychological maladjustment. The majority of those examined as the leader have a trophotropic (non-optimal) type of mental adaptation to conditions of long-term work at sea, characterized by a decrease in the psychophysical reserves of the body, increased anxiety with the choice of a strategy of passive adaptation to extreme environmental conditions.
Рeculiarities of respiratory indicators in naval specialists with signs of professional burnout
Authors: Soshkin P. A.
Published: July 2021

Introduction.A decrease in ventilation capacity entails a significant change in the kinetics of respiratory gases, which can lead to the formation of hypoxic, hypo- or hypercapnic states, which sharply limit the adaptive capabilities of the body and facilitate the formation of professional burnout syndrome, which predetermines the relevance of their study.

Purpose: to assess respiratory performance in naval professionals who have (or do not) show signs of professional burnout.

Materials and methods.The study involved 250 naval specialists aged 25 to 45 years, divided into 2 groups — with the absence (group 1 (n=91 people)) and the presence (group 2 (n=159 people)) signs of professional burnout, in which respiratory indicators.

Results and its discussion. It was found that naval specialists with signs of professional burnout, as compared to those who do not have it, have significantly higher indicators for peak volumetric velocity, instantaneous and average volumetric vital capacity velocity, reserve expiratory volume, as well as assessing the ratio of reserve inhalation to exhalation volume; at the same time, such persons had a significantly lower index of the reserve inspiratory volume.

Conclusion. It is advisable to take into account the indicators of the functioning of the respiratory system, which is of decisive importance in providing the body with oxygen, which ultimately determines the success of adaptation and the prevention of the occurrence of unacceptable functional states, which include professional burnout.
Mathematical model of the influence of the deep pain sensitivity threshold in divers and divers on the clinical symptomatics of decompression disease
Authors: Alpatov V. N. , Sovietov V. I. , Yatmanov A. N.
Published: July 2021

Purpose of the study: to develop a model for predicting the development of a painless form of decompression sickness from the level of pain sensitivity.

Research method:29 divers and divers aged 20 to 42 with decompression sickness and asymptomatic gas formation were examined.

Results and discussion. Painless forms are 1.6 times more common than decompression sickness with painful (classical) clinical manifestations. Determining the pain threshold for divers and divers is an important element in the prevention of chronic decompression sickness. When a diver’s or diver’s pain threshold is 10 volts or more, an ultrasound examination should be performed at each dive for the presence of intravascular gas formation. In such divers and divers, any symptoms that occur after decompression should be considered decompression sickness.

Authors: Platonova Svetlana Yurievna , Torres Mino Carlos Javier , Gins Ekaterina Muratovna , Gins Murat Sabirovich , Romanova Elena Valerievna
Published: July 2021

The article focuses on phenological features of amaranth varieties grown in open fields as a reaction to variability of weather conditions in the Moscow region. Amaranthine is one of the promising compounds found in red-colored amaranths. It refers to a class of betalain pigments. The study revealed growth stages defined by the highest content of amarantine per plant and analyzed accumulation of the pigment in amaranth leaves and inflorescences. Phenological observations of introduced plant species under new conditions are important and determine their resistance to adverse environmental factors, ability to produce high quality fruits and seeds, and potential for cultivation. During the introduction of new amaranth varieties, the most adapted forms were selected for the conditions of the Non-Chernozem zone of the Russian Federation in 2013-2016. The studied Russian and Ecuador varieties were divided into 4 groups depending on the growth period (from germination to seed maturity). Analysis of phenological traits of plants confirmed that period of amaranth development did not depend on the variety, except the fourth stage of late-ripening cultivars - Don Pedro and Eku 17020, dependent on weather conditions. Being dependent on weather conditions, the vegetative growth period turned to be the most stable. Late cv. Eku 17020 did not form mature seeds in open ground conditions, which is explained by its origin (Ecuador). In the present study we identified growth stages when plant raw materials had the highest dye content in red-leaved amaranth varieties (Valentina, Don Pedro and Fakel). We also considered the perspective of cultivation of green-leaved varieties with red inflorescences - Pamyati Kovasa and Eku-17020 - as sources of biologically valuable compounds in the Moscow region.

“Between Heaven and Earth”: A.N. Tolstoy’s Fiction of 1918–1919
Authors: Vorontsova Galina N.
Published: July 2021

The article is based on the thesis that in the writer’s works it is always possible to trace the existence of periods marked by the emergence of new themes and motives. As a rule, this is due both to external circumstances and the artist’s reaction to them, his internal feeling of the need to change the paradigm of his further development. In the work of A.N. Tolstoy one of such periods was the era of the Russian Revolution of 1917 and, in particular, the first revolutionary years, which are characterized by artistic experiments of the writer, allowing to talk about a definitely new vector of his searches. The article analyzes Tolstoy’s stories Mercy!, Peter’s Day, Count Cagliostro and Delirious in the context of the writer’s artistic searches of the 1918–1919. The writer’s work within the boundaries of small prosaic genres at that time allowed him, already in the second half of 1919, to come close to the creation of a full-scale canvas about the Russian Revolution, the novel The Road to Calvary.
Ethno-cultural Borderline: Conceptual, Typological, and Circumstantial Aspects (Alien — Other — One’s own). Third article
Authors: Barabash Yuri Ya.
Published: July 2021

The final part of the triptych is devoted to the problematics of Ukrainian-Jewish literary border. Unlike two previous parts, where geoplitical and regional aspects prevailed (Galitchina, Kharkov — Donbass), here the “internal” border is focused on, or, according to M. Bakhtin, “the dialogical contact between texts (statements)” which implies the priority role of the synchronic approach. As а semantic and methodological “common denominator” for two approaches, the formula for the dialectical interconnection of categories “Alien,” “Other,” “Own” is used. The research is conducted in three directions: 1) the Jewish theme in Ukrainian literature as the “text;” the accent is put on the specificity of literary solutions; 2) writers-Jews in the liminal literary space of Ukraine, the phenomena of cultural diffusions and interferences; 3) Ukrainian writers of the Jewish origin — sociopsychological version of the ethnocultural border.
M.N. Muravyov and Ancient Poets: Unpublished Translations
Authors: Ivinskiy Alexander D.
Published: July 2021

The article is devoted to the translations of M.N. Muravyov. We present more than ten unpublished texts from his Notebook, which is preserved at the Manuscripts Department of the Russian State Library: a number of works of Horace, Virgil, Anacreon, Martial, Callimachus, Lucretius and Lucan. Secondary in this context, but no less important, is the translation of a fragment from the famous poem Jerusalem Delivered by T. Tasso. These texts do not exhaust the subject (many of Muravyov’s translations still remain unpublished), but, along with others, may become the basis for the reconstruction of Muravyov’s literary position, which can already be characterized as oriented towards European “classicism.”
“Geographical Surprises” and More: the Poetics of S.N. Durylin’s Vodlozero Diary
Authors: Korshunova Evgenuya A.
Published: July 2021

The article analyses the poetics of S.N. Durylin’s unpublished North (Vodlozero) diary. The researcher of this diary has the following tasks: to study the text from a functional point of view, to consider the features of genre form and genre content, to try to recreate the image of the author based on the text of the diary. Functionally, Durylin’s Northern diary is interesting because it is a travel essay about the North, in which the author describes not only historically significant landscapes, but also customs of the northerners. The author reveals the intimate experience of what he saw in the North, while the text is distinguished by the objectification of the described, since the notes were supposed to be handed over to the Archaeological Institute. In this case, for understanding the content of the diary genre, it is very important that this is Durylin’s first diary, created on the basis of daily records in July — August 1917, the diary of the so-called formation period, which caused another of its functions — “spiritual chronograph”. Thus, Durylin’s Vodlozero diary recreates the process of spiritual formation of the writer’s personality, and is also a valuable artistic evidence of the Russian national picture of the world.
“...Your Only Choice Now is to Type or to Be a Seller at the Muir and Mirrielees“: on the Creative History of A.N. Tolstoy’s Short Story Without Wings (From the Past)
Authors: Akimova Anna S.
Published: July 2021

“Female issue” probed on the example of A.N. Tolstoy’s diaries for 1911–1914 and his fiction in the article. The biographical, socio-cultural and textological methods were used to describe the writer’s texts. The analysis of periodical and the study of social and cultural life of the early 20th century led to the conclusion that the “female issue” and fates of real women had a great influence on the issues of the short story Masha. The text of the story was published in the Zavety journal in 1914, later Tolstoy prepared it for publication in volume 5 of his Works (1914). The main direction of his corrections was connected with the main character who left her husband and strolled the evening city. The author reduced some details which characterized her as a frivolous lady from tragicomedy or farce, and replaced real names and images with more common things. Tolstoy rewrote the story in 1927. He changed the title (Without Wings (From the Past)) and corrected all characters. As a result the genre of tragicomedy was transformed into tragedy of a lonely young woman “without wings.”

Published: July 2021

This research aims to study the organized crime, its characteristics, and the legislative role in combating it. Due to its reception of many refugees from Syria, Iraq, Yemen, and Libya, the United Arab Emirates (UAE) and Jordan witnessed a widespread of numerous forms of organized crimes such as drug crimes, money laundering, and human trafficking. The authors seek to clarify how Emirati and Jordanian lawmakers dealt with such crime, and whether their legal texts were sufficient and consistent with international conventions. An analytical and comparative approach was the methodology utilized to conduct the study. The authors tackled this research through, the demonstration of the concept of organized crime in the international conventions and national legislation and the viewpoints of Jurisprudence in this regard. Organized crime is described as a threat to national security and as a crime that has dire political implications at the national and international levels (Campbell, 2014). The research has focused on the laws concerning common organized crimes such as narcotic drug trafficking, human trafficking, and money laundering. This research highlighted the efforts exerted by legislators in both countries to combat organized crimes. The findings indicate that both countries enforced specific laws and regulations to stop such crimes
Loving GOD, Loving Others: The Evil of Hatred by Accidental Differences in Humankind
Authors: PhD Michael A. Milton,
Published: July 2021

The rise of ideologies in the West that promote prejudicial treatment of
others based on accidental (humanly uncontrollable) features
(distinguishing ethnic physical traits, geographic origin, physical or
mental capacities, or native cultures, viz., Western
Civilization, that in all of its vicissitudes, has produced distinctive
behavioral, socio-religious, and intellectual norms) is an illogical,
cruel, and nationally  self-destructive worldview that must be exposed
and rejected. The premise of “races” of human beings (Caucasian race,
negroid race, mongoloid race, etc.) , rather than the “race of
Mankind,” male and female, all originating from a common set of
ancestors, created by God, with “in-species” genetic variety (e.g.,
melanin production creating darker or lighter skin color) is not only
unsupported by the teachings of the Old and New Testaments, but singled
out as sins against God. The author examines a recent case of a medical
doctor dreaming of murdering white people. The statement is considered
from both scientific and spiritual viewpoints. The author cites personal
experience in the United States military, as well as peer-reviewed
articles, to establish the hypothesis that the rise of violent tribalism
(“Balkanization”) produces Socialistic authoritarianism, which
forcibly reunites divided “tribes” under the flag of autocratic rule.
This opinion-editorial article concludes by asserting that the Gospel of
Jesus Christ is the powerful antidote that liberates people from the
pestilent consequences of original sin to discover authentic fraternity
in our common Imago Dei (the image of God in
Man), and transformative freedom from the effects of the Fall,
i.e., to embrace and be embraced by a divine love that transcends our
sin. Only in knowing such love can we be free from the hatred that
divides, the bitterness that excludes, and the pain and sorrow that
inevitably follows.

This paper studies the commutativity and stability for the Heun’s linear
time-varying system (LTVS) with both zero and non-zero initial
conditions(ICs). Given a LTVS A of order 2 , we find it’s commutative
pair, that is a new LTVS B of order m ≤ n . Explicit commutative
theories and conditions for second-order LTVSs are derived and solved to
simplify and guarantee the equivalency between the connected
input-output of systems A B and B A . The explicit results obtained are
juxtaposed by simulation in order to investigate the commutativity of
Heun’s differential system, sensitivity of Heun’s system, effects due to
disturbance on Heun’s system, robustness on Heun’s system and problems
regarding the stability of Heun’s system. This findings will help to
fill the gap on stability problem, system behaviors, commutativity
theory, and general theory for solutions of differential equations,
which has significant contribution to science and unlimited application
in engineering, our results are verify using Heun’s differential system
as well as authenticated by Wolfrom Mathematica 1 1 and Matlab.

Anderson’s White-bellied Rat, Niviventer andersoni (Thomas, 1911)
(Muridae, Niviventer) is an species endemic to China. In the
present study, we have sequenced the first complete mitochondrial genome
of N. andersoni using next-generation sequencing. The 16,291 bp
mitochondrial genome consists of 22 transfer RNA genes, 13
protein-coding genes (PCGs), two ribosomal RNA genes, and one non-coding
control region (D-Loop). Phylogenetic analyses of the nucleotide
sequences of all 13 PCGs, PCGs minus ND6 and the entire mitogenome
sequence except for the D-loop, produce nearly identical, well-resolved
topologies. Our results support that N. andersoni clustered with
N. excelsior and form a sister group with N. confucianus,
and they statistically reject the hypothesis from one cytochrome b
(cytb) gene tree that N. confucianus is sister to N.
fulvescens. Our research may be helpful to further reconsideration of
clearer taxonomy and improve our understanding of mitogenomic evolution
in the genus Niviventer.

Cholinesterase inhibitors have been shown to improve cognitive
functioning in patients with Alzheimer’s Disease (AD), but are
associated with side effects and only 20-40% of the patients clinically
improve. In this study, we aimed to investigate the acute
pharmacodynamic (PD) effects of a single dose of galantamine on CNS
functioning in mild to moderate AD patients and its potential to predict
long-term treatment response. This study consisted of a challenge phase,
in which a single dose of 16 mg galantamine was administered to 50 mild
to moderate AD patients in a double-blind, placebo-controlled cross-over
fashion. Acute PD effects were monitored with use of a CNS test battery.
In the subsequent treatment phase of the study, patients were treated
with open-label galantamine according to regular care. After 6 months of
galantamine treatment, patients were categorized as either responder or
as non-responder based on their MMSE, NPI and DAD scores. An analysis of
covariance was performed to study the difference in acute PD effects
between responders and non-responders. Acute decreases of absolute
frontal alpha (-20.4; 95%CI=-31.6,-7.47; p=.0046), beta (-15.7; 95%
CI=-28.3,-0.93; p=.0390) and theta (-25.9; 95%CI=-38.4,-10.9; p=.0024)
EEG parameters and of relative frontal theta power (-3.27%;
95%CI=-5.96,-0.58; p=.0187) on EEG after a single dose administration
of galantamine significantly distinguished long-term treatment
responders (n=11) from non-responders (n=32) after 6 months. This study
demonstrates that patients who demonstrate a reduction in EEG power in
the alpha and theta frequency after a single administration of
galantamine 16 mg will most likely respond to treatment.

Authors: Kara Augustine
Published: July 2021

COVID-19 virus pandemic resulted to abrupt closure of higher education institutions globally as a strategy to manage its spread. This has extensively impacted on the core functions of higher education which include teaching, research and community service. Through a desktop review of relevant literature, the study explored the impacts, mitigation measures adopted, emerging challenges and the future of higher education in the context of COVID-19. The pandemic disrupted the academic calendar, research activities, displaced students, and there has been loss in revenue streams and human resources. It is likely to affect sustainability of local and international higher education. Higher education institutions responded by leveraging the use Information Communication technology (ICT) to minimize disruptions. Challenges experienced include unreliable internet connectivity and ICT infrastructure, equity in access to remote teaching and learning, staff and students’ readiness, assessment of learning, resource constraints, delivery of field and practical courses and quality assurance in emergency remote teaching and learning. The impacts, responses and challenges have been manifested with gaps and inequalities between learners, institutions and countries. The study envisions widescale uptake of blended delivery of academic programmes, capacity building for staff and students on online pedagogy and a holistic quality assurance framework that infuses achievement of desired learning outcomes with Maslow Hierarchy of needs. Greater emphasis will be placed on the entrepreneurial university, institutional mergers and strategic planning for disasters.

Ion-surface collision studies are carried out with small deuterated hydrocarbon cations i.e. CDx + with x = 2-4 colliding with fusion relevant Beryllium (Be) thin films with ions incident energy as low as 0 eV and as high as Ein = 100 eV. Be films are coated on stainless steel surface by the technique of Thermionic Vacuum Arc (TVA); a novel thin film deposition method with primary as well distinguished characteristic of control of ion flux and respective dose towards the substrate. Prior to scattering, methane-d4 99 atom % D is ionized by electron impact and ions are mass and energy analyzed. Ionization and collisions are performed in ultra high vacuum conditions. In these kinds of collision experiments, we have recorded secondary ion mass spectra and plotted respective incident energy resolved abundances of secondary product ions. Relative abundances in percentage of total secondary ions are plotted and it is observed that such beryllium films can accumulate charged hydrocarbon layers as surface adsorbates. These self assembled layers play a primary role in surface-scattering of primary ions. Moreover, it is seen that bond dissociation energy in lighter hydrocarbons is higher than that for heavier species and shows primarily that the deuterium atoms are loosely bounded to carbon atoms in heavier hydrocarbons than in lighter ones.

Textile wet processes dispose of huge amounts of water and energy in the form of hot wastewater and exhaust gas emissions. A significant amount of water and energy can be conserved by adopting various waste heat and water recovery methods, such as the use of heat exchanger, recycling hot wastewater, steam condensate, and cooling water recovery and reuse. In this study, various waste energy and water conservation methods are summarized to highlight their importance for water and energy conservation. For practical consideration, a detailed assessment of such practiced methods was done in one textile processing industry. The obtained results revealed that a high amount of energy and water could be conserved by adopting various waste heat and water recovery methods, with the advantage of reducing environmental pollution while minimizing the consumption of energy and water.

Texture analysis is an outstanding and fundamental task being used in many medical and computer vision applications. Malfunctioning of the human liver upsets almost all the other organs in the human body. Usually liver infections are difficult to analyze because of inconclusive side effects. More often, the liver could be confronting critically but it may not be significantly unveiled. The main objective of this research work is to provide some standard liver diagnostic measures to minimize the risk factors, as better diagnosis is essential requirement in radiology. The Computerized Tomography (CT) contributes important information to the clinical evaluation of diffuse liver diseases. Haralick texture parameters have been computed on the selected Regions of Interest. B11 is used for discrimination and interpretation of normal and cirrhotic liver diseases. Normal and diseased Liver CT images were collected from Bahawal Victoria Hospital. Normal and cirrhotic liver samples of clinically verified patients were obtained and total 900 Regions of Interest (ROIs) were taken from the selected data. Training of the classes was next step after texture parameter computation. In this work, supervised classification method was used to classify the selected images. In this way, the classes were trained in a supervised manner. The maximum accuracy obtained during this research work was 100%, linear dimensionality was 1 and the linear separability was 0.99%. Results of this research work suggested that texture parameters have high degree of reliability to automatically discriminate similar tissue textures, when regions are obvious. This framework separates benign from malignant liver tumors with moderately high precision and is therefore link up the psychophysics with machine vision to outline, recognize, categorize or discriminate textures.

The thermosyphon is a type of heat exchanger that has been widely used in many applications. The use of thermosyphons has been intensified in recent years, mainly in the manufacture of solar collectors and various industrial activities. A thermosyphon is a vertical sealed tube filled with a working fluid, consisting of, from bottom to top, by an evaporator, an adiabatic section, and a condenser. The study of geyser-boiling phenomena, which occurs inside the thermosyphon is of extreme importance, therefore the experimental analysis of the parameters related to the two-phase flow (liquid-steam), such as void fraction, bubble frequency, bubble velocity, and bubble length are necessary, since these parameters have a significant influence on heat transfer. In this work, a pair of wire mesh sensors was used, a relative innovative technology to obtain experimental values of the reported quantities for measuring these parameters of slug flow in thermosyphons. An experimental set-up is assembled and the sensors are coupled to the thermosyphon enabling the development of the experimental procedure. Here is presented an experimental study of a glass thermosyphon instrumented with two wire-mesh sensors, in which the aforementioned slug flow hydrodynamic parameters inherent to the geyser type boiling process are measured. It was measured successfully, as a function of the heat load (110, 120, 130, 140, and 150 W), the void fraction (instantly and average), liquid film thickness, translation velocity of the elongated bubbles, lengths of the bubbles, and the liquid slug (displaced by the bubble rise up). It was observed that the higher the heat load, the lower is the bubble translation velocity. For all heat loads, based on the measured length of liquid slug (consequent displacement of liquid volume), caused by bubbles rise from evaporator to condenser, it could be affirmed to some extent that both boiling regime (pool and film) exist in the evaporator. The measured average void fraction (80%) and liquid film thickness (around 2.5 mm) during the elongated bubble passages were approximately constant and independent of the heat load.

Published: July 2021

The mechanism of performance degradation of a natural gas combined cycle power plant under high ambient temperature is studied by analysing the performance characteristics and thermal properties of the working fluids. Real operating data under typical seasonal conditions are collected and studied. The results reveal that the power output of the natural gas combined cycle system decreases by 22.6%, and the energy efficiency decreases from 57.28-56.3% when the ambient temperature increases from 5-35?C. Gas turbine total power output and steam turbine power output decrease by 17.0% and 16.2%, respectively, as ambient temperature increases from 5-35?C. The enthalpy difference of the flue gas between the turbine inlet and outlet change slightly with varying ambient temperature. The fuel and air input decrease by 16.0% and 16.2%, respectively, as ambient temperature increases from 5-35?C. By analysing the calculated results, the decrement in air and fuel input d is considered as the immediate cause of system power output reduction. The proportion of power consumed by air compressor reaches 50.4% at 35?C. This is considered to be caused by air compressor idle.

Data-driven approaches have achieved remarkable success in different applications, however, their use in solving PDE has only recently emerged. Herein, we present the potential fluid method, which uses existing data to nest physical meanings into mathematical iterative processes. Potential fluid method is suitable for PDE, such as CFD problems, including Burgers? equation. Potential fluid method can iteratively determine the steady-state space distribution of PDE. For mathematical reasons, we compare the potential fluid method with the finite difference method and give a detailed explanation.

Objective:
Clinical guidelines for people with diabetes recommend
chronic kidney disease (CKD) testing at least annually using estimated
glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio (uACR). We
aimed to understand CKD
testing among people with type 2 diabetes in the United States.

Research
Design and Methods: Electronic health record data were
analyzed from 513,165 adults with
type 2 diabetes, receiving primary care from 24
health care organizations and 1,164 clinical practice sites. We assessed the percentage of patients with both ≥1
eGFR and
≥1 uACR,
and
each test individually, in the 1, 2, and 3 years ending September 2019,
by health care organization and clinical practice site. Elevated albuminuria
was defined by uACR ≥30 mg/g.

Results: The 1-year median testing rate across organizations was 51.6% for both
uACR and eGFR, 89.5% for eGFR, and 52.9% for uACR. uACR testing varied (10th–90th
percentile) from 44.7% to 63.3% across organizations and from 13.3% to 75.4%
across sites. Over 3 years, the median testing rate for uACR across
organizations was 73.7%. Overall, the prevalence of detected elevated
albuminuria was 15%. The average prevalence of detected
elevated albuminuria increased linearly with uACR testing rates at sites, with
estimated prevalence of 6%, 15%, and 30%, at uACR testing rates of 20%, 50%,
and 100%.

Conclusions: While eGFR testing
rates are uniformly high among people with type 2 diabetes, testing rates for uACR
are suboptimal and highly variable across and within the organizations examined.
Guideline-recommended uACR testing should increase detection of CKD.
