Plant aquaporin reconstituted proteoliposomes as nanosystem for resveratrol encapsulation
Authors: Yepes-Molina Lucia , Teruel Jose , Johanson Urban , Carvajal Micaela
Published: August 2023

Aquaporins (AQPs) are intrinsic membrane proteins responsible for
facilitating water transport across biological membranes. AQPs found in
plant membrane vesicles (MV) have been related to the functionality and
stability of the vesicles. In this study, we focused on AQPs obtained
from Brassica oleracea var. L. italica (broccoli) by the great potential
for different biotechnological applications. To gain further insight
into the role of AQPs in MV and advance the biotechnological
applications of AQPs, we describe the heterologous overexpression of two
broccoli AQPs (BoPIP1;2 and BoPIP2;2) in Pichia pastoris, resulting in
the purification of both AQPs with high yield (0.14 and 0.99 mg per gram
cells for BoPIP1;2 and BoPIP2;2, respectively). We reconstituted
purified AQPs in liposomes to study their functionality, showing no
changes in size compared to liposomes. BoPIP2;2 facilitated water
transport, which was preserved for seven days at 4oC and 25ºC but not at
37oC, whereas BoPIP1;2 did not enhance water transport across the
proteoliposome membrane. Additionally, BoPIP2;2 was incorporated into
liposomes to encapsulate a resveratrol extract in proteoliposome
vesicles, resulting in increased entrapment efficiency compared to
conventional liposomes. Molecular docking identified potential binding
sites for resveratrol in PIP2s, highlighting the role of AQPs in the
improved entrapment efficiency of resveratrol. Moreover, a modelling
study was conducted, demonstrating interactions between a plant AQP and
human integrin, which may be a benefit to increase contact and
internalization by the human target cells. Thus, our results suggest
that AQPs-based alternative encapsulation systems can be used in
specifically target biotechnological applications.
Determination of Trace Elemental ratios from Marine Biogenic Carbonates.
Authors: V Satya Chanakya I , Misra Sambuddha
Published: August 2023

An improved method for accurate and precise determination of metal to
calcium ratio in mass limited calcium carbonate samples has been
developed. We used an Agilent 5800 ICP-OES for major
elements (Na/Mg/Sr to Ca) and an Agilent 8900
QQQ-ICP-MS for minor and trace elements
(Li/B/Na/Mg/Al/Mn/Fe/Zn/Sr/Cd/Ba/U to Ca). Our method has a long-term
precision of ≤1%(1s), determined by repeat analysis over different
analytical sessions (n≥6) of multiple external standards spanning a
large range of concentrations. We quasi-quantitatively eliminated
potential matrix effect raising from high [Ca] by analyzing samples
and standards at identical concentrations (∆[Ca] ≤ ±5%) during both
ICP-OES and ICP-QQQ-MS sessions. ICP-OES analyses were done on 200µl of
sample at 60 ppm [Ca], consuming ~30µg of CaCO
per analysis. Whereas trace element analyses by
ICP-QQQ-MS required ~150µl of sample at 20 ppm [Ca],
consuming ~7.5µg of CaCO per analysis.
Thus, the present method allows for high precision determination of
TE/Ca in <40µg of CaCO . The sensitivity and
stability of ICP-OES was optimized for selected elements (Na, Mg, Ca and
Sr) by tuning for gas flows, plasma power, viewing height in order to
select wavelengths which exhibits minimal interferences, high
sensitivity and linearity. For choice of Ca lines, the focus was on the
minimization of self-matrix effect. The optimization of ICP-QQQ-MS
method focused on the selection of right isotope(s) for elements with
minimal to no interferences, relatively high absolute abundance. We
minimized instrumental drift by conditioning the cones with 20 ppm Ca.
Furthermore, the present method allows for precise B/Ca determination
sans the use of HF matrix. In summary, this paper presents an easily
adopted method for determining element-to-calcium ratios, suitable for
analyzing limited-mass carbonate samples including foraminifera and
coral samples from culture experiments, and core-top/down-core samples
using readily-available-instrumentation.
A New Computer-Aided Diagnostic Method for Classifying Anemia Disease: Hybrid Use of Tree Bagger and Metaheuristics
Authors: Yagmur Nagihan , Dag İdiris , TEMURTAŞ Hasan
Published: August 2023

Anemia occurs when the hemoglobin (Hgb) value falls below a certain
reference range. It requires many blood tests, radiological images, and
tests for diagnosis and treatment. By processing medical data from
patients with artificial intelligence and machine learning methods,
disease predictions can be made for newly ill individuals and
decision-support mechanisms can be created for physicians with these
predictions. Thanks to these methods, which are very important in
reducing the margin of error in the diagnoses made by doctors, the
evaluation of data records in health institutions is also important for
patients and hospitals. In this study, three hybrid models are proposed
to classify non-anemia records, Hgb-anemia, folate deficiency anemia
(FDA), iron deficiency anemia (IDA), and B12 deficiency anemia by
combining artificial intelligence and machine learning methods
TreeBagger with Crow Search Algorithm (CSO), Chicken Swarm Optimization
Algorithm (CSO) and JAYA methods. The proposed hybrid models aim to
achieve high performance by better emphasizing the importance of
parameters. To solve the multiclass anemia classification problem, fuzzy
logic-based parameter optimization is applied to improve the class-based
accuracy as well as the overall accuracy in the dataset. The
classification performances of the proposed methods are evaluated using
accuracy, F-score, precision, and recall criteria to build a prediction
model to identify the anemia type of anemic patients. A result of the
study on the dataset taken from the Kaggle database found that the three
proposed hybrid methods outperformed other studies using the same
dataset and similar studies in the literature.
Identify reusable components with a learning approach
Authors: Hasheminejad Seyed Mohammad Hossein , Beigian Zahra
Published: August 2023

Component-based software development has been regarded as one of the
newest trends in the software development industry. In some ways,
component-based software development focuses on reusability. In fact,
high-quality software components refer to components that are highly
cohesion internally, and also have the least coupling with other
components, or in other words, are independent. Thus, using such
components will lead to faster software development. In this way, this
study aims to identify reusable components in software. To do this,
first, software components were extracted from the source code of
software systems. To identify reusable components, an artificial neural
network algorithm has been used. On the other hand, the reusable
components recognized by the evolutionary particle swarm optimization
algorithm have been clustered. In this study, the particle swarm
optimization algorithm was modified to apply to clustering problems.
Finally, with the help of these clusters, the KNN classifier was
trained, and during identifying reused inputs, the cluster to which the
input belongs was determined by the classifier. This way, we will have a
library of reusable components, where similar components are placed in a
cluster. The proposed algorithm was experimentally evaluated on nine
open-source software systems belonging to different domains. The results
of this study show that the counted software components are potentially
reusable and confirm the research findings.
The Effects of a Stably Stratified Region with radially varying Electrical Conductivity on the Formation of Zonal Winds on Gas Planets
Authors: Wulff Paula Naomi , Christensen Ulrich , Dietrich Wieland , Wicht Johannes
Published: August 2023

The outer areas of Jupiter and Saturn have multiple zonal winds,
reaching the high latitudes, that penetrate deep into the planets’
interiors, as suggested by gravity measurements. These characteristics
are finally replicable in numerical simulations by including both a
shallow stably stratified layer, below a convecting envelope, and
increasing electrical conductivity. A dipolar magnetic field, assumed to
be generated by a dynamo below our model, is imposed. We find that the
winds’ depth into the stratified layer depends on the local product of
the squared magnetic field strength and electrical conductivity. The key
for the drop-off of the zonal winds is a meridional circulation which
perturbs the density structure in the stable layer. In the stable region
its dynamics is governed by a balance between Coriolis and
electromagnetic forces. Our models suggest that a stable layer extending
into weakly conducting regions could account for the observed deep zonal
wind structures.

Published: August 2023

Montane snowpack is a vital source of water supply in the Western United
States. However, the future of snow in these regions in a changing
climate is uncertain. Here, we use a large-ensemble approach to evaluate
the consistency across 124 statistically downscaled snow water
equivilent (SWE) projections between end-of-century (2076 – 2095) and
early 21st century (2106 – 2035) periods. Comparisons were performed on
dates corresponding with the end of winter (15 April) and spring
snowmelt (15 May) in five western US montane domains. By benchmarking
SWE climate change signals using the disparity between snow projections,
we identified relationships between SWE projections that were repeatable
across each domain, but shifted in elevation. In low to mid-elevations,
15 April average projected decreases to SWE of 48% or larger were
greater than the disparity between models. Despite this, a significant
portion of 15 April SWE volume (39 – 93%) existed in higher elevation
regions where the disparities between snow projections exceeded the
projected changes to SWE. Results also found that 15 April and 15 May
projections were strongly correlated (r 0.82), suggesting that
improvements to the spread and certainty of 15 April SWE projections
would translate to improvements in later dates. The results of this
study show that large-ensemble approaches can be used to measure
coherence between snow projections and identify both 1) the
highest-confidence changes to future snow water resources, and 2) the
locations and periods where and when improvements to snow projections
would most benefit future snow projections.
Quantitative visualization of two-phase flow in a fractured porous medium
Authors: Liao Zhen , Detwiler Russell L , Cookson Esther S , Lei Wanjun , Chen Yi-Feng
Published: August 2023

Two-phase fluid flow in fractured porous media impacts many natural and
industrial processes but our understanding of flow dynamics in these
systems is constrained by difficulties measuring the flow in the
interacting fracture and porous media. We present a novel experimental
system that allows quantitative visualization of the air and water
phases in a single analog fractured porous medium. The fracture system
consists of a sintered-glass porous plate in contact with an impermeable
glass plate. A reservoir connected to the porous plate allows control of
pore pressure within the porous medium. The fracture fills and drains
through the porous matrix and flow manifolds along two edges of the
fracture. The fracture is mounted in an imaging system that includes a
controlled light-emitting diode (LED) panel and a charge-coupled-device
(CCD) camera. Flow and pressure are controlled and monitored by a
computer during experiments. To demonstrate this system, we carried out
a series of cyclic drainage and imbibition experiments in fractures
bounded by porous media with different pore-size distributions in the
porous matrix. Images of the drainage process demonstrate that the
air-water distribution within the fracture evolves differently than has
been observed in non-porous fractured systems. Specifically, we observed
limited trapping of water within the fracture during drainage.
Conversely, during imbibition, because air cannot exit through the
porous matrix, significant regions of air became entrapped once pathways
to the fracture boundaries became water filled. The differences in phase
evolution led to substantial differences in the evolution of estimated
relative permeability with saturation.

Authors: Gwoździk M.
Published: August 2023

The tests were carried out for a coal-fired boiler heating a single-family house with a floor area of 220 m2. The tests concerned the chimney lining (structure and surface layer - produced oxides/deposits), hard coal (eco-pea coal) and furnace ash. The chimney liner was located in a chimney made of bricks joined with concrete. A chimney liner made of austenitic steel was tested. The chimney liner was operated for 130,000 hours. The chimney insert was studied on the inside and outside each cross-section. Coal with a grain size of 5?21 mm was analyzed. The bottom ash consisted of both loose ash and a mass of glassy sintered ash, the so-called slag. The thorough examinations of the examined materialsincludec: microscopic examinations with a VHX-7000 digital microscope and Jeol JSM-6610LV scanning electron microscopes. Chemical composition analysis by energy dispersive X-ray spectroscopy (EDS) in conjunction with the scanning electron microscopy (SEM) was performed. The surface topography (roughness) was measured with a VHX microscope using a Gaussian filter. Based on the tests, the following parameters were determined: arithmetic mean height, maximum height, height of the highest peak, depth of the lowest depression, root mean square height, skewness, kurtosis.

Published: August 2023

This research focuses on studying the mechanical, tribological, and corrosion behaviors of alloy steels: AISI 4340, AISI 5140, and AISI 8620 by laser hardening, respectively. In light of the tests which have been carried out meticulously, it is concluded that the optimum laser hardening parameter for all steel grades is 4 mm/s scanning speed and 1300?C surface temperature. Micro-structural changes, Vickers hardness as mechanical properties, and tribological properties with reciprocating wear tests were carried out. Furthermore, corrosion tests were conducted. The test results reveal that the maximum hardness is achieved 50-300 ?m below the surface for all laser-hardened steels. Additionally, this study demonstrates that the wear resistance of steel is enhanced by the implementation of laser hardening. This study also determines that laser hardening has a positive impact on lifting the corrosion resistance behavior of AISI 4340 steel. In contrast, the corrosion resistance properties of AISI 8620 steel were reduced nearly by 54.17%.

Using Virtual Reality as Learning Tools on Chemistry: Advantages and Challenges
Authors: Sari Indah , Sinaga Parlindungan , Hernani Hernani , Mudzakir Ahmad , Santria Anas
Published: August 2023

This research aims to elucidate the potential benefits and inherent challenges of employing Virtual Reality (VR) technology as an instructional tool in contemporary educational settings. With an emphasis on understanding teachers' perceptions, the study investigates the difficulties faced during traditional oral teaching and the potential advantages that VR-based pedagogy may bring to the educational environment. The participants of this empirical investigation included 20 educators (11 males and 9 females), who provided their insight on a set of 15 questions specifically designed and later analyzed via Rasch measurement. The Rasch model's assessment provided comprehensive insight into the teaching difficulties experienced by educators and the potential benefits accrued from the application of VR as a teaching aid. The findings indicate that the majority of educators face challenges while instructing through oral methodologies without appropriate pedagogical tools. Conversely, the integration of VR in teaching methods was found to foster students' knowledge acquisition, comprehension, and application in novel situations, augmenting their analytical and evaluative capabilities. VR application was also found to bolster student engagement, motivation, and attention in the learning process. However, despite these promising findings, several obstacles were identified, most notably the cost of VR technology and the requisite technical skills needed for its implementation by educators. The results of this study bear significant implications for future research, particularly as a teaching tool in chemistry. It also prompts a discussion on educators' capacity-building to seamlessly integrate VR technology into existing teaching methodologies.

Published: August 2023

To effectively teach the complex concept of thermodynamics, appropriate and innovative teaching methods are needed to ensure a correct and in-depth understanding. This study aims to evaluate the application of the Problem-Based Learning (PBL) model in teaching thermodynamics to enhance students' comprehension of concepts and argumentation skills. The research utilized a quasi-experimental design with a pretest-posttest non-equivalent control group. Of the 50 participants, two distinct groups were formed through purposive sampling. A total of 27 participants underwent PBL instruction, while the remaining 23 participants received conventional learning instructions. The results revealed that students who were taught thermodynamics using the PBL model exhibited significant improvement in both conceptual understanding and argumentation skills compared to the control group. These participants displayed high engagement in tackling thermodynamic problems. PBL taught them how to argue comprehensively, emphasizing the cultivation of 'how to think' rather than just 'what to think' in addressing thermodynamic challenges. Based on these findings, this study recommends that physics educators consider incorporating PBL as a teaching strategy to bolster students' conceptual understanding and argumentation skills in thermodynamics.
The Spiritual Transformation of the Samin Community in Tapelan Village: A Character Education Insight
Authors: Arif Muhamad , Anwar Chairul
Published: August 2023

The Samin community, historically staunch followers of Iman Adam, resisted the injustices of the Dutch colonial rule using their spiritual beliefs. By the 1980s, a significant shift saw the Samin community in Tapelan Village converting from Iman Adam to Islam. This research probes the history of the Samin community's religious conversion in Tapelan Village from an educational standpoint, seeking insights that could augment national character education. Employing historical research methodologies, this study traverses through phases of (1) heuristic collection of historical sources, (2) validation through source criticism, (3) interpretative data analysis, and (4) historiography. The religious evolution of the Samin community can be demarcated into four pivotal phases: (1) reactive resistance against Dutch colonial policies, (2) a period of self-imposed isolation in teak forests, (3) a phase of skepticism and apathy extending to the initial days of independence, and (4) adaptive cooperation with the emergent environment post-1980s. Analyzed educationally, this conversion journey holds potential lessons for reinforcing national character education, emphasizing religious instruction, honesty, and unwavering loyalty to the nation. The Samin community's religious transformation in Tapelan Village not only chronicles their spiritual journey but also offers pedagogical perspectives instrumental in bolstering national character education.

Published: August 2023

The disposition of critical thinking plays an important role for teachers, particularly in responding to mathematical problems. However, several studies have shown that the disposition to think critically is still low. This descriptive-qualitative research aims to analyze and describe prospective mathematics teachers’ critical thinking dispositions based on their self-confidence. Three subjects were selected from a total of 25 prospective mathematics teachers who were given a self-confidence questionnaire, with very good, good, and poor self-confidence criteria. Data collection was conducted by administering a critical thinking disposition test of the Problems With No Specified Universal Set Given (PWNSUS) type and conducting interviews. The results of this research indicate that prospective mathematics teachers’ self-confidence influences their critical thinking disposition. Prospective mathematics teachers with very good self-confidence fulfill the components of a critical thinking disposition, namely systematicity, self-confidence, inquisitiveness, open-mindedness, and analyticity. Meanwhile, prospective mathematics teachers with good self-confidence fulfill the components of self-confidence, inquisitiveness, open-mindedness, and analyticity. However, prospective mathematics teachers with poor self-confidence only fulfill inquisitiveness and analyticity. Two of the three subjects were unable to achieve two critical thinking components, namely truth and maturity, which can be developed through various exercises.
Ossolineum as a common historical heritage of Ukrainians and Poles
Authors: Dobrzhansky Oleksandr , Prytuliuk Vasyl
Published: August 2023

Historically, it happened that Ukrainians and Poles, during long historical periods, lived within the same states, such as theAustro-Hungarian or Russian empires, the First and Second Years of Partition, and therefore, in fact, both peoples are involved in the formation of cultural heritage such as, for example, the Osolinski library. Being a gift to the city of Lviv at the beginning of the 19th century, the library grew over the following years, and by the beginning of the 20th century it became one of the richest in Central Europe. Due to the change of borders and the state affiliation of Lviv, as a result of two world wars and the criminal negligence of the Soviet authorities regarding the Ukrainian cultural heritage, a significant part of the Ossolineum's funds ended up on the territory of the Republic of Poland. The transfer of Ossolineum funds by the Soviet side of Poland was carried out in several stages between 1945 and 1987. At the beginning of the 90s of the 20th century, the negotiation process began between Ukraine and the Republic of Poland on the return of Ossolineum to its country of origin. In fact, throughout the 1990s and two decades of the 21st century, discussions between Ukraine and Poland about the ownership of Ossolineum and its restitution to Ukraine continued. Unfortunately, all these negotiations, as of today, have not yielded any results.

The purpose of the study is to highlight the perspectives of educational strategies in which the principles of innovation and traditionality are harmonized. The tasks of the article are focused around the search for theoretical-methodological and educational-practical guidelines for the correlation of innovative ideas with the traditional educational space. The research methodology is based on general scientific methods (analysis, forecasting, systematization), which provide an understanding of the foundations and features of scientific and pedagogical discourse; philosophical and scientific methods (synergy, dialectics), thanks to which awareness of the coexistence and interaction of educational elements or development strategies is formed. Elements of the novelty of scientific intelligence are focused on taking into account the cultural norms and traditions of the community in which innovative transformations are implemented in the educational space. Sociocultural realities can play the role of a barrier or a favorable environment for information and communication technologies in the educational sphere. Consequently, educational systems are being transformed in today's dynamic world along with other spheres of social activity, actively using digital potential. At the same time, cultural traditions are a stabilizing factor in innovation processes, which allows us to clearly position the role and status of the digital environment in the educational space. The use of ICT has its own characteristics and determines the priorities of future educational strategies. Conclusion. Therefore, maintaining a balance between the classical educational system and new educational environments is the key to the harmonious development of this sphere of social activity in the context of socio-cultural progress.

Paremia with the word for the designation of natural phenomena in the terms of the naive picture of the ukrainian people's world.
Authors: Rusnak Nataliya , Struk Ivanna
Published: August 2023

The national spiritual treasures of the people include the language, which reflects its outlook, psychics, lifestyle, traditions, culture, rituals and beliefs - all that reproduces the soul of the people and determines the national mentality. The language finds verbal means of characterizing the most diverse phenomena of life, bright in content and form in paremias. Proverbs and sayings are the generalized memory of the people and the result of their observations of life and natural phenomena, which enables the younger generation to formulate views on ethics, morality, history and politics. The topicality of scientific research is determined by the need to study the linguistic specificity of paremiological units in the aspect of the textual organization of this genre as part of the spiritual culture of the Ukrainian nation, which preserves the memory of the people and observations of life and natural phenomena. The purpose of our article is to analyze the linguistic features of paremias with the reference word for nature, in particular, their semantic organization and thematic groups. The following methods and techniques of linguistic analysis are used in the article: system-functional analysis, component method, contextual-interpretive method, method of stylistic analysis. The scientific novelty of the research consists in deepening the knowledge about paremias, in the analysis of the semantic nature of proverbs and sayings, taking into account the means of artistic expression. Conclusions. The analyzed material proves that in the minds of our ancestors, each primary element corresponded to a certain element: water was associated with space, fire with soul, earth with time, air with wisdom. According to the semantics, we distinguished three groups of paremias with a reference word for the designation of nature: observation of nature; paremias with generalizing meaning; didactic paremias. However, paremias with a reference word for nature have different degrees of generalization. It has been studied that proverbs about the seasons are often used in their literal meaning, without subtext or excessive artistic imagery, but there are some that have several meanings. We see the perspective of further research in the analysis of communicative and pragmatic features of Ukrainian paremias.
Maxims in the artistic discourse of Olga Kobylyanska
Authors: Rusnak Yulia
Published: August 2023

The purpose of the article is to analyze the maxims regulating family and domestic relations in the artistic discourse of the prominent Bukovinian writer in terms of syntactic organization, verbal content and semantic diversity. The relevance of the scientific article is determined by the need to study individual verbal manifestations in the artistic discourse of the Bukovіnian writer for the formation of a coherent cognitive-pragmatic concept of her artistic discourse. Research methods. In the article as the main general scientific methods of analysis and synthesis are used, as well as linguistic – descriptive, structural methods and method of component analysis. The novelty of scientific research lies in deepening the study of the artistic discourse of O. Kobylyanska. In addition, the analysis of the maxims in O. Kobylyanska's texts has not yet been the subject of linguistic analysis. Conclusions. Maxims are autosemantic, relatively independent statements based on popular common sense, the writer's intellectual level and precedent phenomena. The class of maxims consists of paremias, which include author's modifications of paremias, sayings based on folk mythologems and author's maxims. Maxims function in the text as a separate statement or as part of the context. Folk paremias function as precedent phenomena in the form of a simple sentence. Author's maxims can take the form of identification sentences. Often, maxims are included in the constructions of vocations, taking the form of direct speech. We fix the author's maxims in the form of a rhetorical question and an exclamatory sentence. In the artistic discourse of O. Kobylyanska, a considerable group of maxims regulates family and household relations. Among them, certain thematic groupings can be distinguished: maxims of an instructive nature, maxims about love, gender characteristics, about women, about married life etc.
