The study was carried out to determine the classes and parameters that influence the water quality in the Straits of Johor using the Marine Water Quality Index (MWQI) method and the multi-variable statistical analysis, namely Principal Component Analysis (PCA). The MWQI method classifies the data sets according to four classes of contaminated, medium, good and very good classes. The data were studied from 2016 to 2017 according to two monsoon seasons - the northeast and southwest monsoons. The results for both seasons were compared to find out the difference. The results of the PCA analysis show the relationships between the parameters studied and determine which parameters are responsible for changing water quality standards. The results of the MWQI method reveals that all stations except WQ14 is in class 3 which is moderated while only WQ14 is in class 4 (contaminated). In terms of monsoon, the results of the analysis at the southwest monsoon station found that 25 out of 35 data were in class 3 while the other 10 were in class 4. In addition, MWQI analysis on the northeast monsoon found that 34 out of 35 data were in class 3 and only one was in class 4. These results show that the water quality in the northeast monsoon is better than in the southwest monsoon. The results from the PCA analysis indicates that fecal coliform, total suspended solids and phosphate influence the water quality at the southwest station while the dissolved oxygen and phosphate parameters influence the water quality at the northeast station due to high positive load values. In conclusion, MWQI was able to determine the class of water whilst PCA allowed the identification of types of parameters that affect the water quality. In conclusion, the two above methods can be used to determine pollution levels in water bodies.

In this study, several analytical models were tested to forecast the surface ozone concentration using Artificial Neural Network (ANN), Multiple Linear Regression (MLR) and Time Series Regression (TSR). Four study areas were selected in this study, namely Seberang Jaya in Penang, Shah Alam in Selangor, Larkin in Johor and Kota Bharu in Kelantan. The main objective of this study is to determine the appropriate analytical models MLR and ANN for surface ozone forecasting in some zones of peninsular Malaysia, to forecast surface ozone concentration with TSR model in several zones of peninsular Malaysia and to compare the performance of each model by the performance index. The performance index that will be shown in this study for the model comparison are root mean square error (RMSE), mean square error (MSE) and determination of coefficient (R2). The ANN model showed better performance compared to the MLR and TSR models in the model comparison in each station. The station in Larkin, Johor provides high accuracy in forecasting surface ozone concentrations for each model with minimum MSE, 0.000009 ppm and RMSE, 0.0042 ppm compared to other stations. The value of R2 is 0.33 which is highest compared to station in Seberang Jaya and Kota Bharu.

The management of solid waste, particularly plastic bottle waste, is becoming increasingly important. The carelessness with which solid waste is managed will have a negative impact on human life. A study was conducted to assess the effectiveness of vocational college students in addressing the problem of discarded plastic bottles. The study was conducted online, with vocational students in Malaysia receiving a link containing animation videos and open-ended questions. The students are then asked for their thoughts on how to solve the problem presented in the video. This study enlisted the participation of 197 vocational college students. The students’ feedback was analyzed using thematic coding analysis in Atlas.ti version 22. According to the findings, this study can be divided into two categories which are initiatives to address the issue of plastic bottle waste dumping and the importance of good plastic bottle waste management and planning. Students’ perspectives on problem-solving initiatives were categorized into seven categories: reuse, awareness, recycling, reducing use, disposal, waste segregation, and enforcement. Furthermore, environmental concerns and health issues are two categories that emphasize the significance of proper plastic bottle waste management. In general, vocational college students are aware of the actions needed to address the real issue of plastic bottle waste. Students are also capable of proposing solutions that are appropriate and in line with government efforts such as the 3R, 5R, and waste segregation at source. Furthermore, students can connect the importance of solid waste management to environmental stewardship and public health.

Permanent magnet synchronous motors (PMSM) are widely used in low to mid-power applications and high-performance drives. They are preferred over brush-type motors and gradually replacing induction motors in various fields of application due to its advantages. Many researchers are proposing new control methods of PMSM drive system. However, the PMSM system is nonlinear and consists of time-varying parameters with high-order complex dynamics. Due to these factors, researchers cannot rely only on simulation results to prove superiority of their proposed controllers. To validate the results obtained by simulation, experimental validation is necessary, where a closed-loop PMSM drive system prototype has to be developed. This paper describes the development of a PMSM drive system prototype with closed-loop current, speed and position feedback using dSpace DS1104 controller board for a 1.93kW three-phase interior-mounted permanent magnet synchronous motor used for experimental validation of a proposed modified fractional order sliding mode speed controller. Using this prototype, the performance of any newly proposed control methods in real applications can be verified. Appropriate signal acquisition procedures of the feedback signals, as described in this work, are crucial to ensure the accuracy of closed-loop performance of the developed drive system.

A photovoltaic (PV) system is a renewable energy system intended to convert sunlight into the usable electricity. Due to the rapid world infrastructure development, the demand for electricity is increasing drastically. One of the promising energy resources is the PV. The required energy demand can be provided by the increase of PV system deployment. Thus, as part of the design, development and implementation of a new PV system, a system design simulation is essential. This is to ensure that the designed system works properly according to design specifications. For this reason, a PV mathematical model is necessary in the development process of the PV system especially in the MATLAB/Simulink software environment. With the developed PV model, the PV system design and simulation is made handy, thus escalates the future energy demand. This work describes the development of the PV mathematical model in the MATLAB/Simulink software environment based on the PV related equations. The equations are formed by the consideration of the equivalent circuit of PV cell. The developed PV model characteristics such as the Power-Voltage (P-V) and Current-Voltage (I-V) curves are obtained as the simulation output in MATLAB/Simulink. The obtained characteristics are compared to the actual PV model A 100W RNG-50D Renogy, as to verify the effectiveness and closeness of the developed PV model to the real PV module. In addition, in the simulation, a dc-dc boost converter is also designed and integrated with the PV model as to verify the PV module and capability as a PV power source. The simulation results with the dc-dc boost converter DC-DC integration have shown that the developed PV model is very effective to be used for the PV system simulation.

The aim of the research is to provide a survey-based result on the individual digital skills and human characteristics of the workforce influenced by digital transformation. The online questionnaire is completed by managers and white collar workers of Hungarian manufacturing companies in spring 2021 (n=489). Descriptive statistics and relationship tests are used for analysing the results. The main findings are: (1) digital transformation reduced the demand for human labour, the workforces have basic digital skills used in a few parts of companies, and the digital transformation has increased the challenge in the lack of digital skills of the workforce. (2) Human characteristics are important as an impact of the digital transformation. (3) The size of the companies influences human characteristics changed as a result of the digital transformation. Managers have to focus on improving human and digital skills of the workforces needed in increasingly digital work environments, therefore providing adequate training is an urgent need while companies undergo digital transformation. The study investigates an important socio-technical phenomena determining how digital transformation places specific demands on individual digital skills. Significant human characteristics such as critical thinking, complex problem solving, adaptability, resilience and creativity are essential to successfully exploit the digital transformation.
A review of experimental studies of creep and creep rupture strength (2004–2021)
Authors:   Institute of Mechanics, Lomonosov Moscow State University, Nazarov V. V.
Published: November 2022

The paper reviews studies conducted between 2004 and 2021 for various metal materials (magnesium-lithium alloy, copper, aluminum alloy, titanium alloy, steel, nickel alloy) in the temperature range from 20 to 1100 °C. In those studies the test results were obtained for isothermal creep under uniaxial tension and complex stress. The number of such studies is limited. This review does not include studies dealing with the chemical interaction of the environment with a metal material. Among these studies there are little-known and unique results. In one of those studies, the creep of a magnesium-lithium alloy at normal temperature was considered for the first time. In another study, creep curves for heat-resistant steel were supplemented with experimental stress–strain diagrams in a wide range of high temperatures. Another distinctive study, for the characteristic times of the creep process, compares photographs of changes in the microstructure and the creep curve up to the rupture time. The review lists studies that found an ambiguity in the effect of biaxial tension on the rupture time in comparison with uniaxial tension. It enumerates complex equivalent stresses with the possibility of describing the relative difference in the rupture time under uniaxial tension, biaxial tension, and triaxial tension.

Published: November 2022

An analytical method has been developed for determining the moment of destruction of thin pipe coatings whose material retains elasticity during cyclic changes in internal pressure. The coating material has the property of strain softening, that is, destruction with increasing deformation occurs as stresses drop. The properties of the coating material are described by a convex-concave potential. Due to damage accumulation resulting from fatigue loading, the properties of the coating material change. Hence, the complete deformation curve degenerates. To determine the moment of destruction, the methods of the mathematical theory of catastrophes are used, which make it possible to find all the equilibrium positions of the system and the point of instability of the deformation process. Due to the degeneration of the properties of the coating material, the catastrophe (loss of stability) approaches the parameters of fatigue loading.

A method has been developed to increase hydrogen sorption by Ti2Ni powder, which consists in mechanochemical alloying by titanium of Ti-Ni powder near the equiatomic composition. This method allows the hydrogen content in the powder material to be increased several times. It is possible to use the developed powder material for the safe storage and transportation of hydrogen in the metal hydride with a high hydrogen content, with reversible adsorption of hydrogen, in comparison with the storage and transportation of hydrogen in compressed and liquid form. The developed method is simple to implement and low-cost; therefore, it is of economic and practical interest. For mechanochemical alloying, a high-intensity planetary ball mill was used, with a drum rotation speed of 1820 rpm and a processing time of 300 seconds. It is shown that, after mechanochemical alloying, the powder Ti-Ni (85 wt%) – Ti (15 wt%) powder consisted of TiNi in two modifications, namely B2 and B19`, and two Ti2Ni phases with different lattice parameters. The existence of two Ti2Ni phases is due to both the inheritance of this phase from the initial Ti-Ni powder (Ti2Ni(I)), and its formation during the interaction of titanium with TiNi (B2, B19`) in the process of mechanochemical alloying (Ti2Ni(II)). The Ti2Ni (II) phase formed by mechanochemical alloying is more prone to interact with hydrogen with the formation of Ti2NiHx hydride than the Ti2Ni (I) phase present in Ti-Ni powder before alloying. The lattice parameter of the Ti2Ni (II) phase increases by 17.6 % during hydrogenation and corresponds to Ti2NiH2.8 hydride; this result exceeds the change in the cell volume of Ti2Ni obtained by other methods.

The paper considers an evolution of the free boundary of a finite volume of a self-gravitating ideal gas moving in the vacuum. Unsteady flows are described by a phenomenological mathematical model, which has the form of a system of nonlinear Volterra integro-differential equations written in Eulerian coordinates. The gas volume moves in a force field generated by the Newtonian potential in general form. The boundary conditions are specified on the free gas-vacuum boundary, which is a priori unknown and determined simultaneously with gas flow construction. Conversion to Lagrangian coordinates allows us to reduce the original problem to an equivalent one, which consists of Volterra integral equations and the continuity equation in Lagrangian form, with Cauchy conditions specified for all these equations. Therefore, the application of Lagrangian coordinates makes it possible, in particular, to eliminate the unknown boundary. The theorem of the existence and uniqueness of the solution in the space of infinitely differentiable functions is proved for this problem. The free boundary is determined as an image of the surface bounding the gas-filled region in reverse transition. Herewith, the method for studying the free boundary is similar to the approach that the authors apply to studying the dynamics of the rarefied mass of a self-gravitating gas. Nu-merical calculations of gas flow are made, including the construction of the free gas-vacuum boundary. The influence of gravitation and the initial gas particle velocity on the formation of gas cloud configuration in the vacuum and on cloud evolution is studied. The results are of interest in terms of solving relevant astrophysical and cosmogonic problems.

The prospects of using nitride-oxide and magnesium phosphate electrical insulating coatings on thin strips of magnetically soft alloys based on silicon iron are considered. X-ray diffraction topography, powder figures, and magnetic measurements have shown that coatings create uniformly distributed tensile stresses in materials, increase uniaxial magnetic anisotropy, and reduce the volume of transversely magnetized domains and the width of longitudinally magnetized ones. This increases magnetic permeability and significantly decreases the coercive force, as well as eddy-current and total (by 20–25 %) magnetic losses. Tensile (magnetically active) coatings enhance the effect of subsequent thermomagnetic treatment of alloys.

Coatings applied onto the surface of specimens made of UHP electrode graphite are studied. Coatings are applied by thermal spraying in two stages: spraying of a sublayer (layer I) of the powder materials being tested; spraying of the main layer of the plasma coating, consisting of a mechanical mixture of fine spherical aluminum (Al) and copper (CuCr1) powders in an equal volume ratio. The adhesion strength between the coating and the graphite surface is studied as dependent on the following factors: sublayer thickness; the type of preliminary surface preparation; the chemical composition of the powder material of the sublayer. It has been found that the highest adhesion strength between the coating and the graphite base is achieved when the sublayer thickness is 80 µm, when a thread with a depth of 1.0 mm is cut on the base surface, and when Al powder is used as a sublayer.
Amish Population Pyramids: Demographic Patterns across Affiliations in the Holmes County, Ohio, Settlement
Authors: Colyer Corey J. , Stein Rachel E. , Corcoran Katie E. , Mackay Annette
Published: November 2022

Research indicates demographic trends within the Amish community remain stable over time, even as Amish populations proliferate. However, most of the research on demographic trends fails to examine variation across affiliations. We use data from Ohio Amish Directory, Holmes County and Vicinity, 2010 to construct age-sex population pyramids for three different affiliations. Population pyramids render the growth, decline, and stability of populations visible. Andy Weaver (or Dan) and Old Order churches present expanding pyramids implying rapid growth, while New Order churches render a stationary pyramid indicating slower growth. Sociologists of religion consistently find that strict churches, cultivating separation from the outside world, tend to grow faster than those that foster accommodation with the outside world. We argue that the data presented in this article suggests a similar dynamic at work in Plain Anabaptist communities.
The Varying Fertilities of the Amish Groups of Holmes County, Ohio
Authors: Troyer Henry
Published: November 2022

The Amish are known for their high fertility, and one of the groups, the Swartzentruber Amish, is known for its exceptionally large families. Opinions vary about the number, but there are many distinct Amish affiliations in the Holmes County, Ohio, area, ranging from the progressive New Order Amish to the ultraconservative Swartzentruber Amish. In this study, fertility was calculated for the five groups large enough for such analysis. The fertilities (i.e., number of live births for women 45 years and over) were notably congruent with the degree of conservatism (from progressive to conservative): New Order, 5.76; Old Order, 6.09; Dan or Andy Weaver, 7.79; Hostetler, 8.68; Swartzentruber, 10.42. The families of the Old Order group (the only group large enough) were subdivided into farming and nonfarming subgroups and families of ministers and families of laymen for fertility comparisons. The farming families subgroup had a higher fertility rate (6.88) than the nonfarming subgroup (5.90), presumably because their labor-intensive work of farming begs for large families. The ministers’ family subgroup also had a higher fertility (6.54) than the laymen’s family subgroup (5.89), the difference being attributed to ministers having a deeper religious commitment than laymen. The interval between marriage and first birth was nearly the same for all five groups. For the Swartzentruber Amish, the interbirth intervals remained short throughout the reproductive span, but for the other four groups, they became progressively longer. The reproductive span of women in the New Order Amish group was 13.75 years. It was progressively longer for the more conservative groups and was longest (17.74 years) for Swartzentruber Amish. These results are consistent with other studies that showed that people with more intense religious practice have larger families than people whose religious practice is less intense.

A rare case report of fibrous hamartoma of infancy: Cyto-histopathological correlation
Authors: Srinivasgowda Bhavya Haaluvagilu , Kenchappa Suresh , Kivade Amresh
Published: November 2022

Fibrous hamartoma of infancy is a rare, benign soft tissue tumor that typically occurs within the first two years of life. The histogenesis is unclear. It is most commonly found in the axilla, shoulder, inguinal region, and chest wall and is usually a solitary malformation located in the subcutaneous tissue or reticular dermis. Local recurrence is uncommon and treatment is largely successful by local excision. The clinical course is typically benign and prognosis excellent. We describe a 7-month-old male with a mass on his left arm that progressively increased in size. The management of a subcutaneous mass in the pediatric patient presents a clinical challenge. The differential diagnosis includes numerous benign and malignant soft tissue tumors. The physical appearance and characteristics of a subcutaneous mass on a child may suggest a malignant process; however, Fibrous Hamartoma of Infancy should be included within the differential diagnosis.

The present work deals with the preparation of ceramic composites and the study of phase transformation. Three mixtures were prepared, the main mixture containing (80 wt%) alumina and (20 wt%) titania and the other two mixtures to which two amounts of silica fume were added at (5 and 10 wt%). The phase transformation was studied at two temperatures: 1200℃ and 1400℃. The X-ray diffraction results at 1200℃ show that the amorphous silica (silica fume) transformed into the crystalline phase cristobalite. At 1400℃, aluminum titanate formed by the reaction of alumina with titania, and mullite formed by the reaction of alumina with silica. The result of scanning electron microscopy shows that the addition of (5 wt%) silica leads to a microstructure with smaller grain size up to (500 nm), a lower porosity (20 vol%), a lower water absorption (7 wt%) and a thermal conductivity (1.514W/m.k).

Published: November 2022

Dental direct block are dental mill blanks made from Yttrium stabilised, presintered and zirconium oxide blanks for the manufacture of dental prostheses. Dental direct presintered blocks with disk-shapede were used to machining the specimens at different rotational speed (10000,20000,40000) r.p.m by After that, the specimens were put through a uniaxial flexure test using balls and loaded in a universal testing machine at a cross-head speed of 0.5 mm/min until they failed. Computer Numerical Control machine (CNC) then sintered at 1600℃. The rotating speed affected the flexural strength, microstructure, crystal phase, and grain size of the studied zirconia. The characterization of samples were conducted using field emission scanning electron microscopy (FESEM) and analyzed with X-ray diffraction (XRD). The results XRD analysis showed the presence of a tetragonal phase in all rotational speeds. The differences in morphology and grain size due to different in rotational speed and grain size increase with increasing the rotational speed about 36%. The best flexural strength was observed at low speed, while Hardness showed little varation (decreasing10%) with increasing rotational speed.

When fossil fuel substitution with biomass is viewed as a potential solution to global warming caused by greenhouse gas emissions, the demand for biomass fuel pellets has increased worldwide. Although agricultural waste is an attractive potential feedstock for fuel pellet production due to its relatively high calorific value and low cost, its excessive ash content is a major drawback. This research investigates the properties of sugarcane bagasse fuel pellets treated by dry and wet torrefaction and evaluates the economic value of selling the fuel pellets, which were priced based on their quality. It was found that the wet torrefaction could significantly reduce the ash content in the product (1% ash content at a torrefaction temperature of above 180°C), resulting in higher quality and more marketable fuel pellets. Consequently, the yield and the net present value of the production of wet torrefied fuel pellets were greater than those of dry torrefied pellets. Nevertheless, the production of fuel pellets from sugarcane bagasse treated by either process is shown to be economically viable.

The research aimed to analyze the land waqf dispute resolution mechanisms in Indonesia and Malaysia to provide the Indonesian government with ideas regarding land waqf dispute resolution laws. The approach adopted was a comparative study that highlights the mechanisms and models of waqf dispute resolution in Indonesia and Malaysia. The results show that the Indonesian waqf dispute resolution mechanism comprises two approaches: juridical and sociological. The juridical approach is based on Waqf Law No. 41 of 2004, Article 62. Meanwhile, the sociological approach is based on local wisdom and policies derived from Islamic law. In comparison, the mechanism for resolving waqf land disputes in Malaysia consists of two routes: the non-litigation channel, which consists of negotiation, mediation, and arbitration, and the litigation path, via the sharia court. In the Malaysian mediation pathway, the mediator and the advocacy institution are State Islamic Religious Councils (SIRCS), assisted by waqf managers and experts. An arbitration mechanism is often chosen because the management of waqf land is, for about 40 percent, associated with business, commerce, industry, and property. The similarities between the two countries are that they are committed to resolving waqf land disputes based on applicable law, the concept of justice, and the desire to protect human rights, minimize expenses, build good relationships after disputes, and provide advocacy for the rescue of the donated land assets.

The influence of the ultrasonic field on lead dioxide electrodeposition from nitrate electrolyte was studied. The adsorption of electroactive particles and the amount of nucleation on the electrode surface were found to have increased as well as the formation of OH-radicals accelerated under the influence of the ultrasonic field. Fine-crystalline deposits of lead dioxide were formed, which contributed to obtaining high current yield of lead dioxide, coefficient increasing of the electrode active mass and increasing of the discharge capacity of the emergency current generator cell layout. It was shown that the application of ultrasound in producing a lead dioxide electrode made it possible to reduce the time of the technological procedure.
Multimodal аnalysis in genre studies: Semiotics of the tourist booklet
Authors:   Penza State University, Belgorod State National Research University, Dubrovskaya Tatiana V.
Published: November 2022

The paper discusses the complex genre of tourist booklet as a fixed type of multimodal text that serves in a communicative situation of promoting a tourist product. This genre is a semiotically complex phenomenon, which conveys information through different semiotic systems. The methodological issues are posed as to a perspective model of genre analysis that would take into account the multimodal nature of genres. The author points to major hindrances that an analyst faces when doing multimodal analysis. The study focuses on discovering mechanisms of the interplay between verbal and visual components on semantic and formal levels, as well as showing how the elements of multimodal analysis can be targeted at various genre parameters. The booklets (85 items) for the study were collected in 2007–2019 in Australia, Great Britain, Germany, Poland, Russia and other countries. Methodologically, the paper draws on speech genre theory, semiotics, critical discourse analysis, and multimodal analysis. The claims are advanced that the tourist booklet has both obligatory and optional features, the visual component being obligatory. It is revealed that the colours of visuals can have factual and modal meanings embedded in them; photos convey precedent meanings; while using different semiotic codes, visual and verbal elements join the convergence relations and, thus, provide for genre coherence. The complex genre includes intertextual links between genres in its structure. These links may be of cross-code nature, since they are established between the elements of different semiotic systems, verbal and non-verbal. The conclusion is drawn that a consistent analytical model for multimodal genres has to be designed.
Anathema: Transformation of the genre in the secular and postsecular eras

Published: November 2022

The purpose of the article is to give an outline of those multilateral changes which the speech genre of anathema has undergone in Russian culture of the XIX–XXI centuries, and to shed light on the causes of these changes. Since anathema belongs to sacred performatives, whose pragmatic success directly depends on a set of metaphysical views peculiar to the Middle Ages, the fate of their entire subsystem in the conditions of global spiritual shifts of Modern and Postmodern eras is traced by means of an example of that genre. It is proved that, although anathema has not gone out of use in the Russian Church, it has undergone genre conservation in one direction and hybridization in another, as well as a serious theological rethinking. This latter process began after the excommunication of Leo Tolstoy (1901), the event that had an extraordinary resonance in the early twentieth century. In connection with it, “The Definition of the Holy Synod” is analyzed. It was the main performative which created that event and became a new milestone in the genre history of the Russian-Orthodox anathema. It is shown that this, as well as subsequent documents of that type, were determined in its genre specificity by the contemporary worldview context, the memory of the genre and a number of secondary factors.
