Revisiting pure component wax esters as basis of wax-based oleogels
Authors: Brykczynski Henriette , Wettlaufer Till , Flöter Eckhardt
Published: December 2021

Current research on wax-based oleogels indicates wax esters to be the
key component in many natural waxes. This necessitates understanding the
properties of pure wax esters to unravel the gelling mechanism in
wax-based oleogels. Therefore, wax esters with different carbon numbers
and symmetries were studied and characterized regarding their thermal
(DSC) and viscoelastic (oscillatory rheology) behavior. Pure wax esters
and binary mixtures of wax esters were studied as such and in oleogels
formed in combination with medium chained triglyceride oil at
WE-inclusion levels of 10 % (w/w). Interpretation of the observations
was based on detailed analysis of pre-existing data on crystallographic
(SAXS) and thermal properties. It is found that all observations
concerning single pure WE’s obey a systematic framework linking
molecular make up, crystal structure and behavior. The study on the
gelling of four different binary mixtures of wax esters revealed that
substantial chain length differences do have the expected consequence of
separate crystallization. Mixtures of wax esters with only limited chain
length difference reconfirmed earlier speculations on mixing and crystal
structure. Applying mixtures of wax esters only differing in their
position of the ester bond indicated ideal mixing behavior in the solid
phase of the gels. Actually, the data revealed that despite these
expected observations in both systems, additional thermal events occur
at specific mixing ratios. Their supposed relation to compound formation
certainly needs further confirmation. Rheological analysis confirmed
that sequential crystallization results in highest firmness values for
the systems studied.
Human amniotic epithelial cells exert anti-cancer effects through secretion of immunomodulatory exosomes

Published: December 2021

We identified here mechanism by which hAEC exert their anti-cancer
effects. We showed that vaccination with live hAEC conferred effective
protection against murine colon cancer and melanoma but not against
breast cancer in orthotopic cancer cell inoculation model. hAEC induced
strong cross-reactive antibody response to CT26 cells, but not against
B16F10 and 4T1 cells. Neither heterotopic injection of tumor cells in
AEC-vaccinated mice nor vaccination with hAEC lysate conferred
protection against melanoma or colon cancer. Nanosized AEC-derived
exosomes (ADE) induced apoptosis in CT26 cells and inhibited their
proliferation. Co-administration of ADE with tumor cells substantially
inhibited tumor development and increased CTL responses in vaccinated
mice. Our results clearly showed that it is ADE but not the
cross-reactive immune responses against tumor cells that mediate
inhibitory effects of hAEC on cancer development. Our results
highlighted the potential anti-cancer effects of exosomes derived from
hAEC.

Published: December 2021

This study was carried out to optimize formulation for Heracleum
Lasiopetalum (golpar) extract nanoencapsulation by response surface
methodology (RSM). The primary emulsion was fabricated by (5-10 %)
golpar extract (GE), (40-35 %) emulsifier span 80 (EM), and (50-60 %)
sunflower oil (SO). The coating materials of nanoencapsulation were the
composition of Lepidium sativum seed gum (LSG) and whey protein
concentrate (WPC) at different ratios (1:0, 1:1, and 0:1). The yield of
nanoencapsulation of golpar extract, particle size, and zeta potential
was investigated as responses of RSM. The optimal formulation for
nanoencapsulation of golpar extract were SO: 50.46%, GE 9.52%, and EM:
36.30% in LSG, SO: 57.07%, GE: 7.12%, and EM: 30.85% in LSG:WPC, and
SO: 54.98%, GE: 9.05%, and EM: 39.87% in WPC coating. In conclusion,
the nanoencapsulation of golpar extract prepared with the optimized
formulation by RSM ensures the gradual release and sedimentation during
storage with nanometric size and high yield of encapsulation. The
nanocapsules of golpar extract can be used as a natural antioxidant in
food systems.

Authors: Muhammad Aslam  , Chaudhary Abid Hussain
Published: December 2021

Workplace Spirituality (WS) is recognized as inner state of individuals and an aspect of their working life. This study was conducted to evaluate the psychometric properties of Workplace Spirituality Scale (WPS) developed by Petchsawang and Duchon (2009) in Pakistani context school teachers. The participants for this study were 400 public school teachers. The present study was a quantitative research and cross-sectional survey design was applied. The data were collected personally by researchers and necessary guidelines were shared with the respondents.  EFA and CFA were applied to evaluate the psychometric properties of Workplace Spirituality Scale (WPS) in Pakistani context. The results confirm the four factors model (transcendence, mindfulness, compassion and meaningful work) and generalizability of WPS. Furthermore, statistical analysis established adequate reliability and validity of WPS. The modifications in this scale are mentioned, and recommendations for further research are discussed.
Take a Public Speaking Course and Conquer the Fear
Authors: Karen Kangas Dwyer  , Davidson Marlina
Published: December 2021

The purpose of this research project was to investigate if students today still report a fear of public speaking more often than death and if after completing a public speaking their fears change. Participants in a multi-section public speaking course (N = 374) completed a pre- and post-course survey asking them to select their fears and also complete public speaking anxiety questions. The results showed that pre-course public speaking was chosen more often than death and all other fears except for family tragedy, but after completing the course, the fear of public speaking was no longer selected more than death and was not even among the top five fears students listed. The review of literature also addresses why students should enroll in a basic public speaking course and conquer their fear or anxiety about public speaking while still in college.
Mediating Role of Fluid Intelligence Between Working Memory and Academic Achievement of University Undergraduates: Does Gender Matter?
Authors: Niazi Sadia , Adil Adnan
Published: December 2021

The present study examined the mediating role of fluid intelligence between working memory (WM) and academic achievement and tested the invariance of this model across gender in a random sample of university students (N = 560, 228 boys & 332 girls). Heart and Flower task (Diamond, 2013) and Raven’s Standard Progressive MatricesTM Plus (Raven, 1998) were used to operationalize WM and fluid intelligence, respectively. Academic achievement was operationalized through the CGPAs of students. Findings of the path analysis suggested that fluid intelligence mediated between WM and CGPA. Test of the model invariance indicated that fluid intelligence was a stronger predictor of academic achievement for boys as compared to the girls, which suggested that the indirect effect of WM on academic achievement through fluid intelligence was stronger for boys. Significant gender differences were observed as girls’ mean scores on WM and academic achievement were higher than those of the boys.
Axiological role of emotionality
Authors: Govedarica Milanko
Published: December 2021

The paper explores the specificity of emotional processes, within total
mental dynamics of personality. It is explained that they have both
subjective and objective dimension, that they concern the selection of
individual attentional priorities, but also seeing the objective order of
values. The characteristics of emotional evaluation are considered and the
optimal form of human emotions is examined. Incorrect and correct emotions
are differentiated, whereby formal meaning of super-subjective correctness,
that is, the value dignity of man?s emotionality is explained. Certain
relevant aspects of axiological understanding of emotions at Max Scheler and
Ronald de Sousa are compared. Finally, the author presents arguments in
favor of his own thesis that the objective dignity of not only individual
emotions, but also the total emotional life of personality is attainable.
Two linguistic models of the context-sensitivity of ‘know’
Authors: Milunovic Bojan
Published: December 2021

This article aims to assess the validity of two linguistic models of the
context-sensitivity of the term ?know?: (I) indexical model, according to
which knowledge ascriptions are context-sensitive due to an unstable
Kaplanian character of the term ?know?, and (II) hidden-indexical model,
that explains context sensitivity of ?know? by referring to its semantic
similarities with gradable adjectives. This article is structured as
follows. Section 1 briefly reviews contextualism as an epistemic position
and introduces key features of both models. Section 2 establishes criteria
for their evaluation: (A) their compatibility with our common linguistic
practices, and (B) their compatibility with a contextualist solution to the
problem of philosophical skepticism. Sections 3 and 4 examine two of the
most prominent objections that aim to prove that each of these models fails
to meet one or both of the aforementioned criteria. The article concludes
that the hidden-indexical model, supplemented by Bloom-Tillman?s
Modifiability Constraint, provides the more adequate linguistic support for
the thesis of epistemic contextualism.
Mass transfer and Cattaneo-Christov heat flux for a chemically reacting nanofluid in a porous medium between two rotary disks
Authors: Habu Peter , Noor Noor , Siri Zailan
Published: December 2021

This paper examines the transport of a chemically reacting nanofluid in a
porous medium between two rotary disks with Cattaneo-Christov?s heat flux.
The non-linear ordinary differential system formed under Vonn Karman
transformation of a non-linear partial differential system is solved via a
shooting method with MATLAB bvp4c. The nanofluid thermodynamics profiles
with variation in physical properties of thermal relaxation time, thermal
radiation, porosity, and chemical reaction are observed. Axial, radial, and
tangential velocities are found to be increasing functions of porous
medium. A decrease in the fluid temperature is perceived as thermal
radiation and thermal relaxation increase since more heat can be transported
to neighboring surroundings. The concentration is enhanced with intensified
Cattaneo-Christov?s thermal relaxation but it oscillates with reacting
chemicals. The rotary disks bound the oscillating nanofluid from downward to
up-ward directions and vice versa. The axial velocity represents the change
in force due to porosity and radial stretching of the disks.

Comparing the drying characteristics of apple and kiwi fruits
Authors: Ozgen Filiz
Published: December 2021

In this study, the effects of drying air velocity on the organic apple and
kiwi fruits that were sliced in same sizes were experimentally examined in a
convective type dryer. In order to examine the effect of drying air velocity
to drying process, drying air at 45?C and 10% relative humidity was applied
to kiwi and apple fruit samples sliced in 4 mm thickness at 0.5, 1.0, and
1.5 m/s drying air velocities. It was observed from the experimental
results that drying air velocity has a significant effect on the total
drying time. The drying time of apple and kiwi slices under these
conditions varied between 150-360 minutes. The lowest drying time (150
minutes) was obtained at 1.5 m/s for the apple sample with 4 mm slice
thickness, and the highest drying time (360 minutes) was obtained at 0.5 m/s
for the 4 mm thick kiwi sample. Freshly collected products were successfully
dried in a convective dryer at different velocities.

Authors: Kalaiarasi K. , Soundaria R. , Kausar Nasreen , Agarwal Praveen , Aydi Hassen , Alsamir Habes
Published: December 2021

In many stock disintegration issues of the real world, the decay pace of
certain things might be influenced by other contiguous things. Depending on
the situation, the influence of weakened items can be reduced by eliminating
them through examination. We specify a model that impacts the average
monthly cost, and the non-linear programming Lagrangian method is solved the
specified model. The fuzzify inventory model is used to determine the lowest
cost by employing a trapezoidal fuzzy number, and the defuzzification
process is performed using the graded mean integration representation
method. To test the model, we created a CSV file, used PYTHON (version
3.8.5), we developed a program to predict the economic order quantity and
total cost.

Authors: Talib Imran , Alam Nur , Baleanu Dumitru , Zaidi Danish
Published: December 2021

In this article, we solve numerically the linear and non-linear fractional
initial value problems of multiple orders by developing a numerical method
that is based on the decomposition algorithm coupled with the operational
matrices approach. By means of this, the fractional initial value problems
of multiple orders are decomposed into a system of fractional initial value
problems which are then solved by using the operational matrices approach.
The efficiency and advantage of the developed numerical method are
highlighted by comparing the results obtained otherwise in the literature.
The construction of the new derivative operational matrix of fractional
legendre function vectors in the Caputo sense is also a part of this
research. As applications, we solve several fractional initial value
problems of multiple orders. The numerical results are displayed in tables
and plots.
Pre-stroke physical activity in relation to post-stroke outcomes – linked to the International Classification of Functioning, Disability and Health (ICF): A scoping review
Authors: Viktorisson Adam , Reinholdsson Malin , Danielsson Anna , Palstam Annie , Stibrant Sunnerhagen Katharina
Published: December 2021

Objective: This scoping review aims to identify how pre-stroke physical activity (PA) has been studied in relation to outcomes after stroke using the ICF framework. Methods: MEDLINE, CINAHL, Scopus, and grey literature databases were systematically searched from inception to March 15, 2021, with no language restrictions. Risk of bias was evaluated for all included studies. Identified outcome measures were linked to ICF components using linking rules, and the main findings were summarized. Results: Of 3664 records screened, 35 studies were included. The risk of bias was graded as moderate to critical for all studies. There were 60 unique outcome measures studied in relation to pre-stroke PA, covering the hyper acute to chronic phases of stroke recovery. Outcome measures linked to body functions were most common (n=19), followed by activities and participation (n=14), body structures (n=7), environmental factors (n=4) and personal factors (n=2). There were large differences in assessments of pre-stroke PA, and only one study analysed haemorrhagic cases separately. Conclusions: Pre-stroke PA has been studied in relation to all components in the ICF framework.  However, this review highlights the high risk of bias, heterogeneity in pre-stroke PA assessments, and the lack of information regarding haemorrhagic strokes in the current literature.
Lay Abstract
We used the International Classification of Functioning, Disability and Health (ICF) to categorise the outcome measures of 35 studies. The ICF includes the following domains of health: body functions, body structures, activities, participation, and environmental factors. We identified 60 outcome measures, covering all domains of the ICF. Most common were measures related to body functions such as stroke symptoms, cognition or respiratory function, and activities or participation, such as functional recovery and walking ability. Few studies evaluated personal and environmental factors. Most studies collected information on physical activity before the stroke after the stroke had occurred, and all studies used self-reported information which is problematic from a scientific point of view and can lead to erroneous results. Future studies are needed to determine the true impact of physical activity on outcomes after stroke.

Strictly Confidential Anthropology
Authors: Kürti László
Published: December 2021

Anthropological interest in secrecy and silence – and related aspects such as lying, knowledge, memory, and forgetting – has been long and precarious. Through what may be called personal anthropology, in this article, I describe both private and professional anthropological experiences including family memories, fieldwork sites, and academic practices. By recalling state socialist ideology, censorship, and family secrets, I illustrate how citizens have relied on each other in order to counter state hegemony. I highlight how surveillance in Romania expressly encouraged my informants as well as the secret police to engage in mutual intelligence and observation tactics as evasive tactics. Building on these strategies, I argue that academic life is not immune to secrecy, silence and covert action. I introduce an anthropologist who worked for the Hungarian secret police, and consider how academic life continues to rely on covert programs and an institutionalized hierarchy to promote and maintain its structures and interests.
Silent Traces and Deserted Places
Authors: Joyce Aimée
Published: December 2021

This article explores how silence is held and transmitted through the materiality of deserted and abandoned places along the Polish frontier; and the generative role that silencing plays in local practices of tolerance. The article discusses two specific sites of silence in a town on Poland’s eastern border. Both sites were abandoned or destroyed at the same time, and are part of a larger landscape of religious and ethnic conflict in the area. This history of conflict is managed through small everyday acts of forgetting, minimising and silencing. Yet, the two sites at the centre of this article demonstrate that silencing is an incomplete process. The fragmented materiality of the two places undercuts local silences, actively invoking experiences and memories of the Holocaust. The objects missing and present in these haunted places are too inconsequential to be considered ruins – one site is notable only because it is an empty field. Yet these sites and objects act as powerful silent traces. Traces, as Napolitano (2015) has observed, are knots of history with an ambiguous auratic presence, located between memory and forgetting, repression and amplification. Traces conjure that which we can and that which we cannot say. The deserted places of the town draw attention to the silences that conviviality is built upon. This article considers how paying close attention to the specific silences concerning ‘unthinkable’ histories can reveal the power relations embedded in the process of history making and community building not just nationally, but also at the local level (Trouillot 1995).
Combined creep and hydrogen attack of petro refinery steel
Authors:   , Baker Andrew J.
Published: December 2021

The thesis is based on the study of the interaction between creep and hydrogen attack, with particular emphasis on the commonly used 2.25Cr-lMo steel. The driving force for the work is the petrochemical industry, where large steel reactor vessels used for hydro-cracking and other processes, are known to suffer damage by hydrogen attack. Currently, no reliable method exists for determining the lifetime of these vessels, due partially to the difficulty of obtaining experimental data under the necessary' high hydrogen pressures and temperatures.A large part of the thesis involved the design and building of unique, high-tech testing facilities which could operate safely and accurately under the severe conditions required for such a study. The test rigs were then used to perform both simple uniaxial creep and internally pressurised tube tests in hydrogen environments. Pressurised tubes were used to provide a stress-state more closely related to that found in industrial components. Such experiments allow more accurate extrapolation to industrial pressure vessel behaviour than would be possible with uniaxial data alone.The creep results, together with careful metallography, showed the damaging effect of hydrogen attack on creep life and ductility, or conversely, the accelerating effect of applied stress on hydrogen attack. Tube testing revealed an effect of the multiaxial stress and demonstrated the importance of the hydrogen concentration in the steel.The above results were used to develop a Continuum Damage Mechanics (CDM) model for the prediction of tubular behaviour when pressurised with hydrogen. Within the range of conditions studied, the model was successful and further creep testing work is suggested to verify and develop the model further, as well as to study in greater detail the hydrogen attack mechanisms.
DIFFERENTIATED PRE-ADIPOCYTES ACT AS A DRIVING FORCE FOR PROSTATE CANCER PROLIFERATION, MIGRATION AND EPITHELIAL-MESENCHYMAL TRANSITION

Published: December 2021

Obesity is a popular topic due to both its mortality and morbidity rates and related diseases such as cardiovascular diseases, diabetes and cancer. Cancer development and progression relate to many factors one of which is dysfunctional adipocytes found in the tumor microenvironment. However, underlying molecular mechanisms of the obesity-cancer link have not been fully understood. In the current study, condition media (CM) obtained from differentiated pre-adipocytes was used to set an indirect co-culture system with the prostate cancer cell line. Firstly, adipogenesis of 3T3F44-2A was checked by oil red o staining and expressions of specific genes. CM of differentiated 3T3F44-2A was applied on prostate cancer cells (PC3). Cell viability, migration capacity and related gene expression levels of the cells were evaluated. 20% CM increased cell viability after 48h. The administration also induced proliferation, migration and epithelial-mesenchymal transition (EMT)-related gene expressions. The results presented the roles of adipocytes found in the tumor microenvironment and this could allow new therapeutic developments. As a new perspective to evaluate the obesity-cancer link, our model experiment may also be useful for other cancer types.

Authors: Zhukova Valentina , Tarasenko Vira
Published: December 2021

The article develops a rational recipe composition and technology for the preparation of functional dairy cakes enriched with pumpkin seed flour, the quality of finished products is assessed.

It is shown that the correction of traditional recipes of products of mass demand and daily nutrition in accordance with the nutritional needs of the population is one of the most relevant in the context of a healthy lifestyle. Local plant raw materials with preventive and functional properties are analyzed. It has been suggested that a part of wheat flour should be replaced in the recipe by pumpkin seed flour with a higher content of proteins, lipids, carbohydrates, fiber, vitamins, macro- and microelements.

The relevance of scientific research is to solve the important problem of purposeful search for cheap local plant ingredients with high physiological activity and selection of their optimal dosage in recipes to increase biological and nutritional value, as well as taste properties of finished products.

The aim of the research was to improve the technology of preparation of dairy cakes of high biological value with the use of non-traditional raw materials, as well as to study changes in the quality indicators of finished cakes. In the course of research, the dependence of the mass fraction of moisture of the finished cakes on the dosage of pumpkin flour was determined.

It is established that at replacement of 5-20% of wheat flour on pumpkin humidity of products changes insignificantly and remains within norm. The degree of baking of cakes was determined by the difference in weight of the product before and after baking. It was found that with increasing the dose of pumpkin seed flour, the baking rate decreases. It is determined that at a content of 15% and above of pumpkin flour in the recipe of the cake have a pronounced taste and smell of pumpkin seeds. Organoleptic analysis showed that the optimal amount of pumpkin flour in dairy cakes is 10%.

Experimental samples have a well-developed porosity, pleasant, sweet taste, with a slight tinge of pumpkin seeds. The results of the study may be useful for manufacturers of functional foods.

Published: December 2021

Objective: This study aims to calculate the medical costs of Covid-19 patients for hospitals based on the severity of clinical care.
Design: The study was conducted in a hospital in Istanbul/Turkey. A micro-costing approach was performed using historical cost data for one year. All direct and indirect medical inputs were determined in quantities and monetary values for four types of Covid-19 patients in the hospital.
Results: The analysis calculated the unit cost of an outpatient to be 459,99 ₺, while the cost per day for inpatient to be 1.184,63 ₺, for non-intubated in intensive care unit to be 1.938,11, for intubated in the intensive unit to be 2.393,99₺. The study also indicates that the total cost of a non-intubated patient in intensive care units is 1,54 times higher than the total cost per inpatient. An intubated patient’s cost is 2,08 times higher than an inpatient’s cost.
Conclusion: This study indicates that Covid-19 patients incur significantly high costs for hospitals. The findings of the study provide empirical data for different types of patients which can be used in clinical management and can help all related governing bodies to plan their actions and make the decisions
Impact of Covid-19 on the Mental Health of Healthcare Workers: Predisposing factors, prevalence and supportive strategies
Authors: Pujari Pranjali , Pujari Purvi , Kumar Anuj
Published: December 2021

The massive upsurge of hospitalizations and deaths in the wake of COVID-19 pandemic has placed an unprecedented strain on the psychological well-being of the healthcare workers (HCW) worldwide. The concern about being viewed as unfit for duty by employers or “mentally weak” was the primary reason given. In addition, a majority of HCWs insisted that improvements on the administrative front would have a better impact. An extensive literature review for this paper has been done through databases like Pubmed (Medline) and Google scholar to compile information from various sources. A study of the causative and exacerbating factors, corrective and preventative measures applied, and direct feedback from HCW reveals that much work is yet to be done to develop a satisfactory approach towards ensuring the mental wellbeing of one of the greatest assets in the fight against the pandemic.

Systematic Literature Review of The Effects Of Clinical Mentoring On New Graduate Registered Nurses’ Clinical Performance, Job Satisfaction And Job Retention
Authors: Vidal Jo-Anne Marie , Olley Richard
Published: December 2021

Objective: The purpose of this systematic literature review is to appraise contemporary research literature examining the effects of mentoring on graduate registered nurses’ transition to practice objectively and systematically.  These areas, specifically examined, are competence, job satisfaction, and retention. Three themes emerged from the research in this area. The themes are informal mentoring effectiveness, the extent of mentoring, and mentoring efficacy.
Methods: The PRISMA method was implemented. Articles reviewed were written in English and published between December 2015 and December 2020 and obtained from the Griffith University Library electronic catalogue. A quality assessment of each record not excluded in the title and abstract analysis was undertaken using the method described by Kmet.[1] Those with a quality rating of 16 as a minimum are included in this systematic literature review.
Results: Three quantitative, two qualitative and two - method research studies emerged after applying inclusion criteria, selection, and quality assessment. The analysis demonstrated the positive effects of mentoring on all three avenues with one mixed-method study that documented a downward trend in job satisfaction at six months.
Conclusions: Mentoring is an effective transition to practice strategy for novice nurses. It affects competence, job satisfaction and retention positively. Retention and resignation rates worsen following 12 months of employment. Robust and rigorous studies are essential to justify long-term mentoring programs’ cost-effectiveness.

Review on the Performance Evaluation of Thermal Exchangers using Different Baffle Designs
Authors: Mishra Ajeet Kumar , Daniel Prof. Shamir , Asthana Prof. Amit Kumar
Published: December 2021

The thermal performance of a heat exchanger depends upon various parameters like inlet temperature of hot fluid, type of hot fluid, type of cold fluid, the shape of baffles, the material of baffles, baffles angle, and property of ribs. Basically fluid flow and heat transfer characteristics largely depend upon the Reynolds number (Re). Reynolds number is basically the ratio of inertia force to viscous force. Re is only the factor by which we can decide whether the fluid is laminar or turbulent in shell and tube type of heat exchanger. The heat exchanger is an adiabatic device in which heat is transferred from one fluid to another fluid across a plate surface. In this paper, we have introduced some special types of triangular baffles with rectangular channels. The purpose of this apparatus is to enhance the performance of the heat exchanger. Heat exchangers, nowadays, are one of the most important heat & mass transfer apparatuses in industries like oil refining; heat treatment plants, electric power generation, etc. are long service life.
