Published: September 2021

Bilaterally symmetric flowers have evolved over a hundred times in angiosperms, yet orthologs of the transcription factors CYCLOIDEA (CYC), RADIALIS (RAD), and DIVARICATA (DIV) are repeatedly implicated in floral symmetry changes. We examined these candidate genes to elucidate the genetic underpinnings of floral symmetry changes in florally diverse Rhododendron, reconstructing gene trees and comparing gene expression across floral organs in representative species with radial and bilateral flower symmetries. Radially symmetric R. taxifolium Merr. and bilaterally symmetric R. beyerinckianum Koord. had four and five CYC orthologs, respectively, from shared tandem duplications. CYC orthologs were expressed in the longer dorsal petals and stamens and highly expressed in R. beyerinckianum pistils, whereas they were either ubiquitously expressed, lost from the genome, or weakly expressed in R. taxifolium. Both species had two RAD and DIV orthologs uniformly expressed across all floral organs. Differences in gene structure and expression of Rhododendron RAD compared to other asterids suggest that these genes may not be regulated by CYC orthologs. Our evidence supports CYC orthologs as the primary regulators of differential organ growth in Rhododendron flowers, while also suggesting certain deviations from the typical asterid gene regulatory network for flower symmetry.

Published: September 2021

The drug development process can greatly benefit from liver-on-a-chip platforms aiming to recapitulate the physiology, mechanisms, and functionalities of liver cells in an in vitro environment. The liver is the most important organ in drug metabolism investigation. Here, we report the development of a hybrid cyclic olefin copolymer (COC) and polydimethylsiloxane (PDMS) microfluidic (HCP) platform to culture a Huh7 hepatoma cell line in dynamic conditions towards the development of a liver-on-a-chip system. The microfluidic platform is comprised of a COC bottom layer with a microchannel and PDMS-based flat top layer sandwiched together. The HCP device was applied for culturing Huh7 cells grown on a collagen-coated microchannel. A computational fluid dynamics modeling study was conducted for the HCP device design revealing the presence of air volume fraction in the chamber and methods for optimizing experimental handling of the device. The functionality and metabolic activity of perfusion culture were assessed by the secretion rates of albumin, urea, and cell viability visualization. The HCP device hepatic culture remained functional and intact for 24 h, as assessed by resulting levels of biomarkers similar to published studies on other in vitro and 2D cell models. The present results provide a proof-of-concept demonstration of the hybrid COC–PDMS microfluidic chip for successfully culturing a Huh7 hepatoma cell line, thus paving the path towards developing a liver-on-a-chip platform.

Authors: Wang Feiyue , Liao Jiahao , Yan Long , Liu Hui
Published: September 2021

A novel diaminodiphenylmethane (DDM) modified ammonium polyphosphate (APP) flame retardant, DDP, was successfully synthesized via ion-exchange reaction. DDP was introduced into epoxy resins (EPs) to reduce flammability. A comparable level of DDP exerts better flame-retardant and smoke suppression efficiencies in EP than APP. An EP blend containing 15 wt% DDP displays a limiting oxygen index (LOI) value of 37.1% and a UL 94 V-0 rating, and further exhibits a 32.3% reduction in total heat release and a 48.0% reduction in total smoke production compared with pure EP. The presence of DDP greatly facilitates char formation during combustion, and the char mass from thermal decomposition of an EP blend is 37.8% smaller than that of an EP blend containing 15 wt% DDP at 800 °C. The incorporation of DDP into EP blends has a smaller impact on the glass transition temperature and tensile strength than those of a comparable level of APP. This reflects the better compatibility of DDP with the EP matrix compared with that for APP.

Published: September 2021

A series of polyimide (PI) films with a high-temperature-induced shape memory effect and tunable properties were prepared via the facile random copolymerization of 4,4′-oxydianiline (ODA) with 4,4′-(hexafluoroisopropyl)diphthalic anhydride (6FDA) and 4,4′-oxydiphthalic anhydride (ODPA). The trigger temperature can be controlled from 294 to 326 °C by adjusting the ratio of monomers. The effects of monomer rigidity on the chain mobility, physical properties, and shape memory performance of as-prepared copolyimide were systematically investigated. The introduction of ODPA could enhance the mobility of PI macromolecular chains, which made chain entanglement more likely to occur and increased the physical crosslinking density, thereby improving the PI’s shape recovery up to 97%. Meanwhile, the existence of 6FDA enabled PI films to set quickly at low temperatures with a shape fixation of 98%. The shape memory cycling characteristics of the polyimide films are also studied, and the relationship between the PI chemical structure and the film properties are further discussed.

Published: September 2021

Organic photovoltaic research is continuing in order to improve the efficiency and stability of the products. Organic devices have recently demonstrated excellent efficiency, bringing them closer to the market. Understanding the relationship between the microscopic parameters of the device and the conditions under which it is prepared and operated is essential for improving performance at the device level. This review paper emphasizes the importance of the parameter extraction stage for organic solar cell investigations by offering various device models and extraction methodologies. In order to link qualitative experimental measurements to quantitative microscopic device parameters with a minimum number of experimental setups, parameter extraction is a valuable step. The number of experimental setups directly impacts the pace and cost of development. Several experimental and material processing procedures, including the use of additives, annealing, and polymer chain engineering, are discussed in terms of their impact on the parameters of organic solar cells. Various analytical, numerical, hybrid, and optimization methods were introduced for parameter extraction based on single, multiple diodes and drift-diffusion models. Their validity for organic devices was tested by extracting the parameters of some available devices from the literature.

Published: September 2021

With an increasing interest for molded pulp product (MPP) in the industry, it is important to fully understand how the manufacturing process is different from papermaking. One specific way to differentiate the processes is to compare their resulting products. As the paper industry uses several wood fibers with various pulping processes, it is interesting to compare some of these fibers, to further progress our understanding of the MPP process. In this study, six different wood fibers were used (as received) and analyzed to obtain the sample with the lowest moisture uptake and highest tensile properties. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and fiber analysis module (MorFi) observations were performed, as well as moisture uptake measurements after sorption and tensile tests. We observed significant differences between the fibers tested. Kraft fibers (bleached softwood kraft pulp (BSKP), bleached hardwood kraft pulp (BHKP), and unbleached softwood kraft pulp (USKP)) showed smoother surfaces and less non-cellulosic molecules, such as hemicellulose, lignin, and pectin, in the SEM images. Bleached chemi-thermomechanial pulp (BCTMP) and recycled pulps (R-NPM and R-CBB) both showed non-cellulosic molecules and rougher surfaces. These results were confirmed with the FTIR analysis. With kraft fibers, MPP mechanical properties were lower than non-kraft fibers. Resulting moisture uptake is in between the recycled fibers (lowest moisture uptake) and BCTMP (highest moisture uptake). The removal of non-cellulosic molecules reduces the mechanical properties of the resulting MPP. The incorporation of non-wood molecules, as found in recycled fibers, also reduces the mechanical properties, as well as moisture uptake, when compared with BCTMP.

Published: September 2021

This work investigated the combined effects of CNF nucleation (3 wt.%) and PLA-g-MA compatibilization at different loadings (1–4 wt.%) on the crystallization kinetics and mechanical properties of polylactic acid (PLA). A crystallization kinetics study was done through isothermal and non-isothermal crystallization kinetics using differential scanning calorimetry (DSC) analysis. It was shown that PLA-g-MA had some effect on nucleation as exhibited by the value of crystallization half time and crystallization rate of the PLA/PLA-g-MA, which were increased by 180% and 172%, respectively, as compared to neat PLA when isothermally melt crystallized at 100 °C. Nevertheless, the presence of PLA-g-MA in PLA/PLA-g-MA/CNF3 nanocomposites did not improve the crystallization rate compared to that of uncompatibilized PLA/CNF3. Tensile strength was reduced with the increased amount of PLA-g-MA. Contrarily, Young’s modulus values showed drastic increment compared to the neat PLA, showing that the addition of the PLA-g-MA contributed to the rigidity of the PLA nanocomposites. Overall, it can be concluded that PLA/CNF nanocomposite has good performance, whereby the addition of PLA-g-MA in PLA/CNF may not be necessary for improving both the crystallization kinetics and tensile strength. The addition of PLA-g-MA may be needed to produce rigid nanocomposites; nevertheless, in this case, the crystallization rate of the material needs to be compromised.
Increasing the Gas Barrier Properties of Polyethylene Foils by Coating with Poly(methyl acrylate)-Grafted Montmorillonite Nanosheets
Authors: Rauschendorfer Judith E. , Vana Philipp
Published: September 2021

Low-density polyethylene (LDPE) foils were coated with a thin film of polymer-grafted Montmorillonite (MMT) nanosheets, which form a barrier against gas diffusion due to their unique brick-and-mortar arrangement. The MMT nanosheets were grafted with poly(methyl acrylate) (PMA), a soft and flexible polymer. Already very thin films of this nanocomposite could reduce gas permeability significantly. The impact of the topology of the surface-grafted polymer on gas permeability was also studied. It was found that grafting MMT nanosheets with a mixture of star-shaped and linear PMA and with PMA that is cross-linked via hydrogen bonds further decrease gas permeability. The presented strategy is quick and simple and allows for the easy formation of effective gas barrier coatings for LDPE foils, as used in food packaging.

Published: September 2021

Over the years, the persistent occurrence of superfluous endocrine-disrupting compounds (EDCs) (sub µg L−1) in water has led to serious health disorders in human and aquatic lives, as well as undermined the water quality. At present, there are no generally accepted regulatory discharge limits for the EDCs to avert their possible negative impacts. Moreover, the conventional treatment processes have reportedly failed to remove the persistent EDC pollutants, and this has led researchers to develop alternative treatment methods. Comprehensive information on the recent advances in the existing novel treatment processes and their peculiar limitations is still lacking. In this regard, the various treatment methods for the removal of EDCs are critically studied and reported in this paper. Initially, the occurrences of the EDCs and their attributed effects on humans, aquatic life, and wildlife are systematically reviewed, as well as the applied treatments. The most noticeable advances in the treatment methods include adsorption, catalytic degradation, ozonation, membrane separation, and advanced oxidation processes (AOP), as well as hybrid processes. The recent advances in the treatment technologies available for the elimination of EDCs from various water resources alongside with their associated drawbacks are discussed critically. Besides, the application of hybrid adsorption–membrane treatment using several novel nano-precursors is carefully reviewed. The operating factors influencing the EDCs’ remediations via adsorption is also briefly examined. Interestingly, research findings have indicated that some of the contemporary techniques could achieve more than 99% EDCs removal.
Double-Walled Poly-(D,L-lactide-co-glycolide) (PLGA) and Poly(L-lactide) (PLLA) Nanoparticles for the Sustained Release of Doxorubicin
Authors: Cardoso M. Margarida , Peca Inês N. , Lopes Telma , Gardner Rui , Bicho A.
Published: September 2021

Double-walled nanoparticles (DWNPs), containing doxorubicin as a model drug, were produced using poly-(D,L-lactide-co-glycolide) (PLGA) and poly(L-lactide) (PLLA) by the solvent evaporation technique. Double-walled microparticles containing doxorubicin were also produced to make possible the examination of the inner morphology and drug distribution using optical and fluorescence microscopy. The produced microparticles present a double-walled structure with doxorubicin solubilized in the PLGA-rich phase. The DWNPs produced present very low initial burst values and a sustained DOX release for at least 90 days with release rates decreasing with the increase in the PLLA amount. Zero-order release kinetics were obtained after day 15. The results support that the PLLA layer acts as a rate control barrier and that the diffusion of doxorubicin from the drug-loaded inner PLGA core can be retarded by an increase in the thickness of the unloaded outer layer. The unloaded double-walled nanoparticles produced were used in in vitro tests with CHO cells and demonstrate that they are nontoxic, while the double-walled nanoparticles loaded with doxorubicin caused a great cellular viability and decreased when tested in vitro.

Published: September 2021

A series of UV-protected coatings were prepared using cerium-oxide-functionalized oil fly ash (f-OFA-CeO2) in waterborne polyurethane (WBPU) dispersions. Three monomers, namely, poly(tetramethyleneoxide glycol) (PTMG), polydimethylsiloxane-hydroxy terminated (PDMS) and 4,4-dicyclohexylmethane diisocyanate (H12MDI), were used to pre-mix with f-OFA-CeO2 separately, followed by the synthesis of WBPU/f-OFA-CeO2 dispersions. The f-OFA-CeO2 distribution and enrichment into any part (top/bottom/bulk) of the coating was strongly affected by the pre-mixing of f-OFA-CeO2. The f-OFA-CeO2 was densely distributed in the top, bottom and bulk when the f-OFA-CeO2 was pre-mixed with PDMS, H12MDI and PTMG, respectively. Only an f-OFA-CeO2-enriched top surface showed excellent UV protection. The lowest UV-degraded exposed coating was found when the top surface of the coating was f-OFA-CeO2-enriched.
Multiscale Simulation of Semi-Crystalline Polymers to Predict Mechanical Properties
Authors: Horn Tobias Daniel , Heidrich Dario , Wulf Hans , Gehde Michael , Ihlemann Jörn
Published: September 2021

A multiscale simulation method for the determination of mechanical properties of semi-crystalline polymers is presented. First, a four-phase model of crystallization of semi-crystalline polymers is introduced, which is based on the crystallization model of Strobl. From this, a simulation on the nanoscale is derived, which models the formation of lamellae and spherulites during the cooling of the polymer by using a cellular automaton. In the solidified state, mechanical properties are assigned to the formed phases and thus the mechanical behavior of the nanoscale is determined by a finite element (FE) simulation. At this scale, simulations can only be performed up to a simulation range of a few square micrometers. Therefore, the dependence of the mechanical properties on the degree of crystallization is determined by means of homogenization. At the microscale, the cooling of the polymer is simulated by a cellular automaton according to evolution equations. In combination with the mechanical properties determined by homogenization, the mechanical behavior of a macroscopic component can be predicted.
Combining Kinetic and Constraint-Based Modelling to Better Understand Metabolism Dynamics
Authors: Moulin Cecile , Tournier Laurent , Peres Sabine
Published: September 2021

To understand the phenotypic capabilities of organisms, it is useful to characterise cellular metabolism through the analysis of its pathways. Dynamic mathematical modelling of metabolic networks is of high interest as it provides the time evolution of the metabolic components. However, it also has limitations, such as the necessary mechanistic details and kinetic parameters are not always available. On the other hand, large metabolic networks exhibit a complex topological structure which can be studied rather efficiently in their stationary regime by constraint-based methods. These methods produce useful predictions on pathway operations. In this review, we present both modelling techniques and we show how they bring complementary views of metabolism. In particular, we show on a simple example how both approaches can be used in conjunction to shed some light on the dynamics of metabolic networks.

Authors: Wnuk Marcin
Published: September 2021

Spirituality is a key element of Alcoholics Anonymous (AA) recovery. However, little is known about the potential religious and secular sources of spiritual experiences in AA fellowship. The aim of the study was to verify if in a sample of AA participants, meaning in life mediates the relationship between their religiousness and spiritual experiences, as well as between their involvement in AA and spiritual experiences. The study sample consisted of 70 Polish AA participants, and the following tools were used: the Alcoholics Anonymous Involvement Scale (AAIS); Santa Clara Strength of Religious Faith Questionnaire (SCSORFQ); Purpose in Life Test (PIL); two one-item measures regarding frequency of prayer and Mass attendance; and the Daily Spiritual Experiences Scale (DSES) duration of AA participation, which was positively related to involvement in addiction self-help groups and religiousness. Involvement in AA and religiousness were positively related to meaning in life, which in turn positively correlated with spiritual experiences. This research indicated that in a sample of AA participants, finding meaning in life partially mediates the relationship between religiousness and spiritual experiences, as well as fully mediating the relationship between involvement in AA and spiritual experiences. The theoretical and practical implications are discussed.

The concept of ecological consciousness and ecological activity is revealed. The values of the development of eco- psychological culture of junior schoolchild are described. It is noted that one of the priority tasks of psychological support at the stage of development of eco- psychological culture of a schoolchild is process of identifying the values and ideas about nature and the environment and appropriate behavior and interaction with nature. It is the value system that determines the type of human relationship with nature. Theoretical aspects of the basic and specific methods of realization of psychological support of development of eco- psychological culture of a schoolchild are considered. Their content, meaning, types and forms of application are substantiated. It is established that to develop the effectiveness of the correct attitude of schoolchild to the environment, they should use various forms and methods of environmental education in class and extracurricular time, in classroom and extracurricular activities. It is in the period of primary school age that schoolchildren begin to quickly form their own conative or behavioral component of environmental consciousness. That is, there is a desire to grow crops, take care of pets, create comfort and coziness in everyday life. It is established that during the psychological support it is necessary to form the ecological responsibility of the junior schoolchild not only in the learning process, but also in the game and knowledge of the environment. This is a kind of psychological and pedagogical process aimed at forming a schoolchild’s knowledge of the basics of nature, gaining the necessary beliefs and practical skills, a certain orientation and active life position in the field of protection, conservation and increase of natural resources.
EMOTIONAL DEPENDENCE IN ROMANTIC RELATIONSHIPS: THE ROLE OF ADVERSE CHILDREN’S EXPERIENCE AND EARLY DYSFUNCTION SCHEMES
Authors: Shyroka A. , Brukh I.
Published: September 2021

Emotional dependency is a persistent pattern of unsatisfied emotional needs, that the individual tries to fulfill in close intimate relationship in particular romantic relationship. Adverse childhood experiences (ACEs) are often identified as a cause of emotional dependency. However, there is plenty of evidence that many psychosocial problems are more strongly associated with early maladaptive schemas (EMS), than directly with ACEs. ACEs and EMS both can have effect on emotional dependency. Such assumption has strong theoretical reasoning, but there is still lack of empirical evidence about the exact role ACEs and EMS can play in emotional dependency. The present study examined early maladaptive schemas as mediators of the adverse childhood experiences – emotional dependency in romantic relationship.

The study has cross-sectional design. Questionnaires completed by 128 individuals (78% females) (Mage=26; SD=9), who currently or in the past were involved in romantic relationship. There were assessed 10 types of childhood trauma (The Adverse Childhood Experiences Questionnaire), early maladaptive schemas (Young Schema Questionnaire-Short Form) and emotional dependency (Emotional Dependency Questionnaire). The mediation role of EMS was tested by Baron and Kenny (1986) analysis strategy using hierarchical multiple regression procedures.

The findings showed that ACEs didn’t predict, but such EMS as abandonment / instability,  mistrust / abuse and failure to achieve did predict emotional dependency in romantic relations (R2=0,44). The experience of emotional neglect mildly predicted schema of mistrust / abuse (R2=0,16).

Such results discussed in the context of previous research, limitations that restricted the study’s conclusions and future research recommendation.
COMPARATIVE ANALYSIS OF COMMUNICATION MOTIVES OF PRESCHOOLERS’ WITH VARIOUS DEGREES OF EMOTIONAL ADMIRATION OF JOINT ACTIVITY
Authors: Yudina N.
Published: September 2021

The article presents the results of theoretical and empirical research of psychological peculiarities of communication motivation of preschoolers who have different degrees of emotional admiration of joint activity. As a result of theoretical analysis, it was found that the most common reason for children to choose a communication partner is the attractiveness of another person as a personality due to the moral, business or physical qualities, a manifestation of sympathy, love to this person, i.e. emotional attitude. At the same time, the need for a more detailed practical study of the problem was confirmed, because the issue of communication motivation in preschool age, in particular, the influence of the degree of emotional admiration of joint activity on this process, remains insufficiently resolved.

The data of an empirical study of the peculiarities of communication motives of preschool children with different degrees of emotional admiration of joint activity showed that the higher the degree of emotional interest of preschoolers for joint activity is, the higher the degree of development of communication motives they have. Parameters such as the subjective significance of a peer for a child, which is manifested in the general admiration of others; peer orientation, i.e. the ability to concede, to help; ability to empathy, as well as the child’s choice (to help or not to help to his or her peers), the degree of emotional admiration of the activity and an indication of its expression (positive or negative); the nature of the child’s behavior, its emotional expression, speech, were used as the main indicators of interpersonal relationships.

It was proved that the degree of preschoolers’ emotional admiration of joint activity is largely correlated with the level of development of their ability to concede and the willingness to help. Thus, the motives of communication of the preschooler with other children differ depending on the degree of his or her emotional admiration of joint activity, because it was found that the higher the degree of emotional admiration of preschoolers is, the higher the level of development of the ability to concede and the willingness to help they have.

Уперше наголошено на можливому зв’язку поміж історією життя і громадської діяльності на захист русинів (українців) польського діяча Яна Щасного Гербурта (1567–1616), долею його Добромильської друкарні, фактом появи в ній двомовної «Трагедії...» Я. Ґаватовича та сприянням цьому Регіни Жолкєвської з Гербуртів. Запропоновано гіпотезу про те, що друк «Трагедії...» міг бути способом символічного, прихованого вшанування пам’яті Яна Щасного Гербурта або ж, принаймні, став невід’ємною частиною польсько-українського культурного діалогу ранньомодерної доби.

Звернено увагу на проблему ідентичності української культури з огляду на відсутність державності та усвідомлення соборності на ментальному рівні й подальше втілення цієї ідеї у мистецьких творах. Співпраця української інтелігенції, її контакти, а також просвітницька діяльність авторка розглядає як вирішальний чинник і предтечу соборності Україні.
Історико-філософське підгрунтя англійської гуманістики другої половини ХІХ століття
Authors: Тернова Марина Володимирівна
Published: September 2021

У статті сфокусовано увагу на історико-філософських надбаннях, які забезпечили теоретичне підґрунтя гуманістики другої половини ХІХ століття. Оскільки на англійських теренах гуманітарне знання формувалося на чітко виражених принципах спадкоємності, врахування досвіду, що передував другій половині ХІХ століття вкрай важливе. Формування такого досвіду передбачало також відкритість як до нових напрямків досліджень, так і до передбачення шляхів розвитку соціальної, етичної та практичної філософії.Однією зі специфічних ознак даної статті є використання засад культурологічного аналізу, серед яких особливого значення надається персоналізації досліджуваного матеріалу. Персоналізація — структурний елемент біографічного методу, він дає змогу підтвердити людинотворчий характер культури, що його послідовно опрацьовують українські науковці.У статті також наголошено значення поступового формування регіонального підходу, який, починаючи від ХVIII століття, визначався елементами діалогу англо-німецької та англо-французької гуманістики.

Echoic Communications and Pragmatic Relevance of COVID 19 Memes in Nigeria’s Social Media Space
Authors: Chinenye Lynda Ambrose , Destiny Idegbekwe
Published: September 2021

There are greater possibilities for a language utterance to have more meanings than what is stated. It is also possible for the hearers/audience to interpret what the speaker has in mind beyond what the speaker has put out in words. These meanings derived in this form are echoic and they are arrived at by choosing meanings that contextually relevant involving the least effort. How echoic relevant definitions are achieved has been studied using different language instances. Still, none in the researchers' knowledge has investigated how the COVID 19 social media memes, as used by Nigerians, communicate deeper meanings that are contextually relevant and how the echoic interpretations reveal the users' attitude. On this basis, therefore, the present study investigated the echoic nature of COVID 19 related social media memes as used by Nigerians. The study used Sperber and Wilson (1986) relevance theory as the theoretical framework and qualitatively analyzed Ten (10) purposefully selected memes. In the end, the study found out that interpretations of memes are significantly linked with the shared cognitive background knowledge which the speaker/meme creator and the hearer/audience have. Also, memes could echo the attitude of concern, disdain and fear while also harboring deeper meanings that contextually relevant and implicit.
