Study on Mechanical Properties of hBN Reinforced Al-7075 Metal Matrix Composite
Authors: N Lokesh
Published: July 2022

Abstract: Nickel-coated hBN particulate reinforced Al7075 matrix composites were developed using the stir casting technique. Al7075 – hBN composites were subjected to tensile test and heat treatment by solutionizing at a temperature of 550 ℃ for a span of 2 hr and then quenched in water at room temperature. Hardness was measured before starting the aging process and further, compacts were artificially aged in the furnace at temperatures of 100, 150, and 200 ℃ for intervals of 60 min. Results have revealed that nickel-coated hBN particles are uniformly distributed throughout the matrix alloy. Microhardness of Al6061- hBN composites increases with an increase in the percentage of reinforcement. Heat-treated Al-7075+4.5% nickel-coated hBN possesses higher hardness when compared with the Al-7075 alloy composites. Also, the hybrid reinforced composites exhibit excellent tensile properties; as compared with base metal (Al7075) and Al7075+4.5% nickel coated hBN show high Breaking Load and Ultimate Tensile Strength. The current studies focused on strength by varying aged harden treatment for Al7075+4.5% nickel coated hBN and their tensile strength.

Design and Implementation of Three Phase Solar PV Integrated UPQC Based on Artificial Neural Networks
Authors: Chatur Prathamesh K.
Published: July 2022

Abstract: Project deals with the design and performance analysis of a three-phase single stage solar photovoltaic integrated unified power quality conditioner (PV-UPQC). The PV-UPQC consists of a shunt and series connected voltage compensators connected back-to-back with common DC-link. The shunt compensator performs the dual function of extracting power from PV array apart from compensating for load current harmonics. An improved synchronous reference frame control based on moving average filter is used for extraction of load active current component for improved performance of the PVUPQC. The series compensator compensates for the grid side power quality problems suchas grid voltage sags/swells. Thecompensator injects voltage in-phase/out of phase with point of common coupling (PCC) voltage during sag and swells conditions respectively. The proposedsystem combines both the benefits of clean energy generation along with. The steady state and dynamic performance of the system are evaluated by simulating in Matlab-Simulink under a nonlinear load. The system performance is then verified using a scaled down laboratory prototype under a number of disturbances such as load unbalancing, PCC voltage sags/swells and irradiation variation.

Published: July 2022

The article purpose was to determine the place of modern higher education in the structure of the global innovative space, considering the preservation of itself as a national identification center, which required understanding and formalization of its new mission for conditions of high geo-economic instability caused by the processes of deglobalization in the world economy.As a research methodology, the work uses a nonlinear method synthesizing systemic and evolutionary approaches. This allows, on the one hand, to determine the place of higher education in the structure of the global innovation space. On the other hand, to reflect the qualitative, evolutionary transformations taking place in it against the background of increasing destabilization within this broader system, respectively, to show the evolution the missions of the higher school under the influence of the changes that have arisen.An important result of the research was the definition of a new mission of the higher school, which consists not only in its acquisition of subjectivity in the creation and promotion of innovations at the global level, but also in its formation as a sovereign (independent) center of national identity with a certain share of its own supranational influence on the world innovation space, including in terms of eliminating the global innovation separation.

Published: July 2022

The article is devoted to the issues of creating a barrier-free environment for free circulation in the intellectual property market of the post-Soviet countries, which today is in a depressing state. One of the factors of its successful functioning is the unification of the regulatory framework, the creation of a single market principle, and the coordination of the work of patent offices. The purpose of the study is to establish the specifics of the work of the patent offices of the Commonwealth of Independent States to ensure adequate mutual protection of intellectual property, including with countries that are not part of the Eurasian Economic Union, but with which the economic and cultural relationships that have been established for decades are maintained. The analysis of organizational management structures in the field of intellectual property in the CIS countries has shown that along with the general principles of their work, there are numerous features of their activities. The main research method was structural-logical and comparative analysis. Common features are identified, positive experience is generalized, typical shortcomings of both organizational structures as a whole and individual structural units are noted. The place of patent offices in the general system of public administration is determined. The specifics of performing functions, the composition of which differs significantly in different countries, are disclosed. The features of interaction with patent offices are determined. Recommendations for improving the structures and the standard structure of the patent office are proposed.

Authors: YILDIZ Derya , KARACA Şura , BAKIRCI Şerife
Published: July 2022

Hayatın her alanında yer alan iletişim becerisinin eğitimde yeri oldukça büyüktür. Özellikle öğretmen ve öğrenciler arasındaki iletişimin güçlülüğü, eğitim ve öğretimin verimli bir şekilde gerçekleştirilmesinde etkili olmaktadır. Öğretmenlerin iletişim becerilerinin iyi olması, öğrencilerle ilişkisini kuvvetlendirmekte; onlara bilgilerin, kültürün, toplumsal değerlerin aktarılmasını kolaylaştırmaktadır. Öğretmenlerin iletişim becerisini etkileyen birçok faktör vardır. Bu çalışmada öğretmenlerin iletişim becerilerinin; cinsiyetleriyle, branşlarıyla, kıdemleriyle, mezun oldukları okul türleriyle, mezuniyet durumlarıyla ve öğrencilerin sınıf düzeyleriyle ilişkisi tespit edilmeye çalışılmıştır. Bu amaçla nicel ve nitel verilerin toplandığı karma araştırma modeli kullanılmıştır. Örneklem grubunu sekizinci sınıfta okuyan 120 öğrencinin değerlendirdiği farklı branşlardan 120 öğretmen oluşturmaktadır. Örneklem grubu belirlenirken amaçlı örnekleme yaklaşımı olan kolay ulaşılabilir durum örneklemesi kullanılmıştır. Araştırmada veri toplama aracı olarak “Öğretmen İletişim Becerileri Ölçeği”; nitel bölümde ise görüşme formları kullanılmıştır. Analizler sonucunda öğretmenlerin iletişim becerileri üzerinde cinsiyetin, branşın, mezun oldukları okul türünün, mezuniyet durumlarının ve öğrencilerinin sınıf düzeylerinin bir etkisi olmadığı; kıdemi az olan öğretmenlerin kıdemi fazla olan öğretmenlere göre iletişim becerilerinin daha iyi olduğu tespit edilmiştir. Nicel bulguları desteklemesi için elde edilen nitel bulgular incelendiğinde, “etkili iletişim” ana teması altında; ‘’değer görme’’, ‘’anlaşılabilme’ ve ‘’gelişime eşlik etme’’ olmak üzere üç alt temaya ulaşılmıştır.
Female CEO and internal control weaknesses
Authors: Hua Shaowen , Sun Xiaojie Christine , Lou Rixing , Chen Hanmei
Published: July 2022

This study examines how the gender of CEOs affects internal controls over financial reporting. According to the upper echelon theory, managers’ demographics can determine the choices of strategies. Prior literature documents the characteristics of CEOs relevant to internal controls, such as the CEO’s age, entrenchment (Lin, Wang, Chiou, & Huang, 2014), and experience (Oradi, Asiaei, & Rezaee, 2020); however, the impact of the CEO’s gender on internal controls has not been explored. We hypothesize that female CEOs are negatively associated with internal control weaknesses because they are reported to act more conservatively and ethically than male CEOs. We use logit and Poisson regression models to test the association between the CEO’s gender and internal control weaknesses of U.S. public companies from 2004 to 2020. Our results show that female CEOs are less likely to report an internal control weakness both in the current year and in the future years. We follow You (2021) and use a two-stage model to address the potential endogeneity concerns and show that our findings are not biased. Our study documents an important factor that influences internal controls, and we provide evidence of the benefits of female CEOs on the quality of financial reports
A passive noise-shaping SAR ADC with energy-efficient switching method
Authors: Yang Puqing , Zhang Zhaofeng
Published: July 2022

In this letter, a low-voltage passive first-order noise shaping
charge-redistribution successive approximation register (SAR) ADC with
energy-efficient switching method is proposed. The energy-efficient
switching method is achieved by one-side switching instead (OSSI) method
and higher-bit switching instead (HBSI) method. The architecture is
modified to realize the noise-shaping loop properly. We present a
passive integrator with a dynamic DC offset to address the path gain
error from the varying voltage on the capacitor array at each
quantization step. Simulation results on a 180nm CMOS technology
operated at 0.6V supply and 25kHz sampling rate show 130nW power
consumption with a peak SNDR of 70.3dB.

Authors: Liu Yanlei , Xu Chao , Dong Wenpan , Chen Xun , Zhang Wen , Sun Yuzhe , Wang Guohong , Wang Yufei , Zhou Shi-Liang
Published: July 2022

Desert areas occupy approximately 25% of total land area and are
characterized by scarce precipitation, poor soil conditions, and a harsh
ecological environment. Desertification may result in the loss of unique
biological resources. Therefore, exploring the biodiversity of deserts
and the causal factors of desertification is necessary to develop future
solutions to global desertification. The desert area in northwest China
is an important part of the arid zone of central Asia as it was traveled
during the ancient Silk Road and witnessed the rise and fall of many
civilizations, making it an ideal location for desertification research.
This study utilized environmental DNA in the surface soil along the
eastern part of the Silk Road and DNA metabarcoding technology.
Bioinformatic analysis identified 782 plant species belonging to 505
genera and 133 families, and plant species diversity gradually decreased
from east to west along the Silk Road. Temperature, altitude, and
longitude were the main factors affecting plant species diversity in the
area, while the impact of precipitation was relatively small.
Correlation analysis between species diversity, population density, and
major human settlements revealed that human activity significantly
affected plant species diversity. Our study successfully used
environmental DNA and metabarcoding technology to reveal the plant
species diversity and its influencing factors for a large-scale desert
area, which will provide a fundamental and theoretical basis for desert
management and biodiversity protection.

Published: July 2022

We presented a patient with an advanced stage of endomyocardial fibrosis
(EMF) who immigrated from Brazil to Framingham, Massachusetts. EMF is an
extremely rare etiology of heart failure in Europe and North America,
although the prevalence is high in tropical countries, including Brazil.
However, as presented in our case, the incidence of EMF would increase
with sporadic cases from immigration to temperate countries. Our case
would help raise awareness and familiarity in diagnosing EMF, a rare and
perhaps one of the most underappreciated causes of heart failure.
Effect of tree species and substrate properties on organic phosphorus forms in afforested technosols
Authors: Chodak Marcin , Sroka Katarzyna , Pietrzykowski Marcin
Published: July 2022

Planted vegetation is considered one of the most important soil-forming
factors in the reclamation of degraded post-mining lands for forestry.
The objective of this study was to compare the effect of N-fixing tree
species and non-N-fixing species on the organic phosphorus (P
) forms in technosols developing from various
substrates. Samples were taken from the uppermost layer (depth 0 – 5
cm) of technosols afforested with black locust ( Robinia
pseudoaccaccia), black alder ( Alnus glutinosa), silver birch (
Betula pendula) and Scots pine ( Pinus sylvestris).
Samples of the tree foliage and the O horizons were taken as well. The
studied technosols developed from Quaternary sands (Sands), fly ashes
after lignite combustion (Ashes) and Miocene clays (Clays). The soil
samples were measured for the contents of labile (P
) and moderately labile organic phosphorus (P
), phosphorus contained in fulvic and humic acids (P
and P , respectively) and
residual organic phosphorus (P ). The foliage and O
horizon samples were measured for the concentrations of C, N and P. The
N-fixing trees had higher P concentration in the foliage than
non-N-fixing species. However, in the O horizon the highest P
concentration was determined under birch and not under N-fixers. The
effect of tree species on the organic P (P )
concentrations in the mineral soil was limited with significantly lower
P concentrations under pine. Soil under this species
contained less P , P and P
. However, the percentages of P
, P , P , P
and P in soil P
were nearly the same under all tree species. The
largest effect on the P concentration and on the
contents of particular P fractions was from the
substrate type. Sands contained much less P than the
Clays and Ashes but their percentage of P in P
was much higher than in two other substrates. We
conclude that N-fixing trees do not affect the concentration of labile
organic P and the major factor controlling this P
fraction is the soil substrate quality.

Digital forensic investigators face a wide range of inquiry goals, such as dealing with cybercrime. Digital forensic tools are no different. Different digital traces were examined on persistent storage devices (SSDs, SD cards, and USB drives), volatile memory snapshots, and network captures. A large realistic, timely training data is required to train experts, improve the forensic tools and keep their knowledge and capabilities up to date. However, there is a significant gap in digital forensic training data due to many factors such as privacy, secrecy, data protection, and intellectual property rights. Multiple frameworks for generating realistic digital forensic data sets have been proposed in recent years. None of these frameworks offers a comprehensive strategy for creating digital forensic tools, for relevant traces, from many sources.

Thermodynamic analyzes in a compression ignition engine using fuel oil diesel fuel blends
Authors: Ozer Salih , Dogan Battal
Published: July 2022

We use fuel oil as an alternative fuel in compression ignition engines
without modification. In this study, we performed tests at different engine
speeds using diesel fuel oil fuel blends in a compression ignition engine.
Energy and exergy analysis was carried out using the performance and
emission values got from these tests. Through energy analysis, the energy
distribution of the engine was determined and the thermal efficiency was
calculated. The highest thermal efficiency is 34.76% on F40 fuel at 2250
rpm. In the exergy analysis, fuel exergy, exhaust exergy, entropy
production, and exergy efficiency were calculated. The highest exergy
destruction is 17.36 kW at 3250 rpm on D100 fuel. The exergy efficiency
increases with engine speed. The highest exergy efficiency is 28.2% on F40
fuel at 2250 rpm.
Flow of water-based Cu, CuO, and Al2O3 nanofluids heated with constant heat flux between micropipe
Authors: Simsek Hatice
Published: July 2022

This study aims to analytically measure the fully developed laminar flow and
heat transfer the water-based nanofluids, Cu, CuO, and Al2O3, within a
micropipe with constant heat flux, under the temperature jump and slip rate
boundary conditions. Knudsen number, nanoparticle volumes, and ratios of
liquid layer thickness to particle radius are assumed, 0, 0.02, 0.04; 0%,
4%, %8, and 0.1, 0.2, 0.4, respectively. The findings suggest that adding
nanoparticles to flow area has significant effect on both the velocity field
and the heat transfer. There is a significant decline in the velocity both
at the core and on the walls in the velocity area, due to the increase in
the solid volume and the ratios of liquid layer thickness to particle radius
after adding nanoparticles to flow area, and the increase of Nusselt number
is significantly proportional to that of the solid volume and the ratios of
liquid layer thickness to particle radius. Among the nanoparticles, Cu, CuO,
and Al2O3, used as nanofluids within the micropipe, Cu is found to be the
one with the highest heat transfer enhancement, followed by Al2O3, and CuO,
respectively.
Our Collapsing Friedmann Universe
Authors: WQ Sumner
Published: July 2022

Edwin Hubble observed that the color of light emitted by atoms from distant galaxies is redder than similar atoms emit today on earth. The farther away the galaxy, the greater this redshift. This redshift has been interpreted as a result of an expanding universe “stretching” the photons as described by Alexander Friedmann’s solution to Einstein’s general theory of relativity. But this interpretation of color shift of photons ignores the fact that atoms as well as photons change with the universe. Atomic emissions change twice as much as photon wavelengths do. When atomic emission changes are included, Hubble redshift implies that the Friedmann universe is collapsing, not expanding. This conclusion is confirmed by modern observations.
Why do we See One Side of the Moon?

Published: July 2022

As a rule, this is explained by the fact that it makes one revolution around its axis during one flyby around the Earth. But what and how makes her do this? There is another explanation-because of tidal forces, but how do they affect and what are tidal forces on the moon? If there are tides, then there must be tides, but they are not detected. In principle, these two explanations are legitimate, but it is necessary to explain a little the mechanics of such a movement. By the way, many satellites behave the same way as the Moon, rotating around their planets
Time-Dependent Quantum Dynamics Study of the Interaction between Helium Atom and Synchrotron Radiation
Authors: Y Ang-yang
Published: July 2022

For the first time, excitation and ionization of helium atom (He) induced by synchrotron radiation(SR) is simulated in the present work. It is found that electrons can tunnel through the ground state of helium atom and leave from the atomic region caused by subsequent SR field. Therefore, the ionization of He atom can happen. Additionally, some electrons can be captured by a higher electronic state, which leads to the tunneling excitation from the ground state to a specific excited state.
Evolution and Dynamics of Quantum Fluids
Authors: S Sengupta
Published: July 2022

Quantum Fluids follow Quantum Dynamical Equation(s), which were not known till date. There exist a set of two equations that is semi classical approach to Quantum Fluids called Madelung’s Equations. But a new fully quantum variant of Madelung’s Equations when embedded in the Schrodinger Equation is gives full description of evolution of Quantum fluid with respect to time and position. The equation presented in this article has two unknown variables, one is density and other is velocity field as a function of spatial and time coordinates. The equation presented in this article, is derived from Schrodinger Equation, obeying Continuity equation, and Navier Strokes Equation. Bohm’s potential was externally added in Madeline’s equation. But the new equation which is fully quantum mechanical in nature; Bohm’s potential appears out of the equation, which is interesting to observe. Astrophysical cold stellar dynamics and condensed fluids have the main application of this equation. Quantum fluids show strange behaviour when compared to normal fluids. It is also shown that quantum fluid also has spins which has no classical analog.

qPCR merupakan metode yang akurat untuk mendeteksi ekspresi gen. Analisis ekspresi gen pengkode faktor transkripsi pada padi saat ini banyak dilakukan. OsAP2, OsERF3 dan OsEREBP2 merupakan faktor transkripsi pada padi yang termasuk kedalam kelompok AP2/ERF yang berperan penting dalam proses biologis pada tanaman. Penelitian mengenai analisis ekspresi gen OsAP2, OsERF3 dan OsEREBP2 pada Cempo Ireng belum pernah dilakukan. Dalam melakukan analisis ekspresi gen menggunakan RT-PCR dibutuhkan primer spesfiik sesuai dengan gen yang diinginkan. Primer merupakan salah satu komponen penting dalam melakukan metode PCR. Gagalnya penempelan primer pada tahapan annealing menyebabkan kegagalan amplifikasi. Optimasi primer perlu untuk dilakukan untuk mendapatkan suhu annealing yang optimal. Pada penelitian ini akan dilakukan optimasi suhu anealing pada 3 gen pengkode faktor transkripsi pada padi yakni OsAP2, OsERF3 dan OsEREBP2. Optimasi dilakukan dengan menggunakan cDNA sebagai template. Konfirmasi hasil qPCR dilakukan dengan menggunakan elektroforesis. Hasil optimasi menunjukkan bahwa suhu annealing optimal pada primer OsAP2, OsERF3 dan OsEREBP2 berada pada kisaran 53,9 – 60 °C.

Teachers Evaluation of Concurrent and Consecutive Teacher Education Models in South-west, Nigeria
Authors: Yusuf Hamdallat Taiwo
Published: July 2022

The provision of quality teachers is central to a nation’s education system. This study evaluated two universities, based on teacher education curriculum models (concurrent and consecutive) using Stake’s Antece-dents-Transactions-Outcomes (ATO) evaluation model, on the subject content and education components. The study was a descriptive type using a survey method. The sample comprised 514 teachers from selected secondary schools (188 consecutive and 326 concurrent), Research instrument was the Teachers Questionnai-re on Evaluation of Models of Teacher Education Curricula (TQEMTEC). The results indicated that teachers rated the consecutive teacher education curriculum model to be better. On the improvements needed, teacher educators suggested the inclusion of special education and more subject contents area for students enrolled in the concurrent, and an increase in the number of years for the pedagogical and practical aspects of the consecutive models. Results of the hypotheses indicated a significant difference between the views of tea-chers exposed to the concurrent and those exposed to consecutive teacher education models on subject con-tent, (t =2.47; df=512; Sig= 0.014 p 0.05). Based on the findings, a recommendation was made that the two models of teacher education should be further strengthened through improved subject content, particu-larly for the concurrent teacher education program.
Pre-service teachers’ mathematical concepts in indigenous languages: Challenges encountered in multilingual classrooms, Rundu urban, Namibia

Published: July 2022

Teaching mathematics in primary schools using indigenous languages as the language of instruction may present a professional challenge for teachers in several ways. Whereas most studies focused on teachers’ use of indigenous language in mathematics classrooms, there seems to be little done on the challenges experienced by pre-service teachers while teaching mathematics in indigenous languages. This study, thus, explored the challenges experienced by pre-service teachers teaching mathematics in indigenous languages at the primary school phase in Namibian multilingual classrooms. The study used a total population sampling technique and involved 90 pre-service teachers at the Rundu campus of the University of Namibia who voluntarily completed the questionnaires. The results showed that pre-service teachers faced difficulties with some concepts that were rather literally translated from English to vernacular. Thus, the translation led to ambiguous meanings. Another challenge was that some of the learners had problems in understanding the concepts in the language of instruction as they had a different mother tongue, for example the Chokwe and Nyemba speaking learners in classes where the medium of instruction is Rukwangali.

One of the cultural outcomes of the Madurese community is the traditional tanean lanjang house with a long front yard, designed from several batih (nuclear) families, consisting of a married couple with unmarried children. This study explores geometric concepts of the traditional house to demonstrate how they can be useful for learning mathematics. The descriptive qualitative study described the mathematical concepts found in the tanean lanjang traditional house or settlement in Madura. Furthermore, an ethnographic method was also used to analyze documents, ethnographic notes, and documentation (photos). Data analysis techniques employed an interactive model of data collection, data reduction, data presentation, and conclusion. The results of the study show that the cultural values and geometric concepts of the tanean lanjang traditional house comprised (1) kinship and brotherhood values, (2) harmony in the household, and (3) strength in the household. The geometric concepts contained in the traditional tanean lanjang house include 2-dimensional shape (i.e., rectangle, trapezoid, triangle), perimeter of 2-dimensional shape, area of 2-dimensional shape, 3-dimensional shape (i.e., triangular prism), the volume of 3-dimensional shape, curve, and the concept of reflection in geometry.
