Previously obtained and certified HfO2 based samples were investigated by two Raman spectrometers with different wave source. Stokes reflexes have to be independent of the laser frequency so they were distinguished by comparison of different laser results. For the first time the dependence of Stokes lines frequencies on the cation radii of dopants was observed. Frequencies monotonically varied with the ratio of cation-dopant to hafnium radii changes. All non-Stokes reflexes are considered as photoluminescence. They were compared with both the literature data on luminescence of REM cations and the experimental results on zirconia-based materials intrinsic photoluminescence, which was a property of its point defects. Intrinsic photoluminescence is observed for the first time on hafnia-based materials.

The structure, IR absorption spectra, luminescence spectra (SL), and luminescence excitation spectra (LES) of La0.99хTbxEu0.01BO3 orthoborates synthesized at 970°С at 0 ≤ x ≤ 0.99 were studied. An increase in x leads to the successive emergence of three structural states of these compounds. At 0 ≤ x ≤ 0.2, orthoborates have an aragonite structure; then, at 0.2 <x< 0.89, they become two-phase and contain the aragonite and vaterite phases. At 0.89 ≤ x ≤0.99, the compounds have a vaterite structure. A correspondence between the structure and spectral characteristics of these compounds was established. It is shown that in La0.99хTbxEu0.01BO3 orthoborates, as well as in La0.99хYxEu0.01BO3, the band with λex= 369 nm (7F0 → 5D2) in the LES and the band in the wavelength range of 577 – 582 nm (5D0→7F0 ) in the SL of these compounds can serve as indicators of the structural state of the sample. In the SL of the samples containing the aragonite and vaterite phases, two bands corresponding to these structures were simultaneously observed for the first time. It was established that the luminescence of Eu3+ ions in La0.99хTbxEu0.01BO3 orthoborates, which occurs when the sample is excited by light in the absorption bands of Tb3+ ions, is due to the transfer of the electron excitation energy from Tb3+ ions to Eu3+ ions. The efficiency of this process in La0.9Tb0.09Eu0.01BO3 samples with an aragonite structure is 86%.

The lattice dynamics of Ba2ZnTeO6 double perovskite in three phases has been studied. Vibrational spectra and dynamic charges are calculated. In the rhomobohedral phase R3 ̅m, soft modes were found; after their condensation, the C2/m phase was obtained, which agrees with the experiment. An assessment was made of the dependence of the enthalpy of different phases on pressure; it showed that the monoclinic phase is more favorable at 0 pressure, but as the pressure increases to 2.9 GPa, the cubic phase Fm3 ̅m becomes advantageous.
Квазилокальные колебания в аморфных твердых телах с точки зрения теории негауссовых случайных матриц
Authors: Конюх Д.А. , Бельтюков Я.М.
Published: September 2022

The statistical features of quasi-local vibrations of disordered systems are studied within the framework of the model of correlated random matrices. It is shown that the statistics of matrix elements of the dynamical matrix strongly affects the properties of such vibrations. The lowest frequency part of the density of states of quasilocal vibrations is described by the expression ρ_qlv(ω) ∝ ω^n, where the power n is the number of neighboring atoms. However, if the distribution of matrix elements is highly non-Gaussian, an additional dependence ρ_qlv(ω) ∝ ω^γ appears, where the power γ decreases as the degree of non-Gaussianity increases.

Published: September 2022

Two ferroelectric phase transitions are observed in the PbFe0.5Nb0.5O3 crystal. The first is between the cubic and tetragonal phase, the second is between the tetragonal and monoclinic phases. To describe phase transitions and emerging phases, a statistical model is proposed, based on the composition of two multi-minimum models - a six-minima model for the Pb cation and an eight-minima model for the Nb cation. Adjusting the model parameters, makes it possible to reproduce all the characteristic features of the thermodynamic behavior of the crystal. The most interesting is the formation of a ferroelectric, complexly ordered monoclinic phase with Cm symmetry. It is shown that the mentioned monoclinic phase arises due to the fact that the first-order phase transition to the rhombohedral ferroelectric phase occurs in the presence of an "external field" of tetragonal symmetry. The contribution of the subsystems of Pb and Nb cations to the features of the dielectric and structural properties of the crystal is estimated.
Hypnotic Regression as an Autoethnographic Modality for Exploring Adverse Childhood Experiences as Proposed Effectors of Chronic Adult Obesity - Selected Case Studies
Authors: Entwistle Paul Andrew
Published: September 2022

Much has been written about the aetiological role of Adverse Childhood Experiences (ACEs) in the development of chronic adult physical and emotional health problems but current screening methods utilising questionnaires and formal interviewing often fail to show consensus across populations and surveys. This paper proposes that hypnotic regression might provide an alternative approach to ACE screening through its facility in revealing unsuspected and seemingly minor ACEs, which nevertheless can go on to have long term implications for individuals’ adult health. In this study seven female participants with intractable overweight volunteered to participate in a series of hypnosis sessions designed to explore for possible covert childhood or early adulthood traumatic experiences which might have contributed towards their adult obesity problems. During their hypnosis sessions all participants were seemingly able to recall and to recount, narratives of long-forgotten but intensely painful childhood experiences, traumas and family disharmony, which appeared to have provoked life-changing decisions regarding their weight, body image or eating habits, and which may then have contributed to their developing refractory obesity later in their adult life. This study suggests that current decisions limiting the range of what constitutes ACEs may account for the differing results of previous ACEs surveys and that hypnosis might prove to be a useful tool in screening for otherwise unrecognised ACEs, thus helping to improve the specificity and sensitivity of current ACE screening programmes.
Barriers and Facilitators Influencing Real-time and Digital-Based Reporting of Adverse Drug Reactions by Community Pharmacists: Qualitative Study Using the Task-Technology Fit Framework
Authors: Fossouo Tagne Joel , Yakob Reginald Amin , Mcdonald Rachael , Wickramasinghe Nilmini
Published: September 2022

Background

Medication use can result in adverse drug reactions (ADRs) that cause increased morbidity and health care consumption for patients and could potentially be fatal. Timely reporting of ADRs to regulators may contribute to patient safety by facilitating information gathering on drug safety data. Currently, little is known about how community pharmacists (CPs) monitor, handle, and report ADRs in Australia.

Objective

This study aimed to identify perceived barriers to and facilitators of ADR reporting by CPs in Australia and suggest digital interventions.

Methods

A qualitative study with individual interviews was conducted with CPs working across Victoria, Australia, between April 2022 and May 2022. A semistructured interview guide was used to identify perceived barriers to and facilitators of ADR reporting among CPs. The data were analyzed using thematic analysis. We constructed themes from the CP-reported barriers and facilitators. The themes were subsequently aligned with the Task-Technology Fit framework.

Results

A total of 12 CPs were interviewed. Identified barriers were lack of knowledge of both the ADR reporting process and ADR reporting systems, time constraints, lack of financial incentives, lack of organizational support for ADR reporting, inadequate IT systems, and preference to refer consumers to physicians. The proposed facilitators of ADR reporting included enhancing CPs knowledge and awareness of ADRs, financial incentives for ADR reporting, workflow-integrated ADR reporting technology systems, feedback provision to CPs on the reported ADRs, and promoting consumer ADR reporting.

Conclusions

Barriers to and facilitators of ADR reporting spanned both the task and technology aspects of the Task-Technology Fit model. Addressing the identified barriers to ADR reporting and providing workplace technologies that support ADR reporting may improve ADR reporting by CPs. Further investigations to observe ADR handling and reporting within community pharmacies can enhance patient safety by increasing ADR reporting by CPs.
Neural Network Modeling of Cutting Force and Chip Thickness Ratio for Turning Aluminum Alloy 7075-T6
Authors: H. AL-Khafaji Mohanned Mohammed
Published: September 2022

The turning process has various factors, which affecting machinability and should be investigated. These are surface roughness, tool life, power consumption, cutting temperature, machining force components, tool wear, and chip thickness ratio. These factors made the process nonlinear and complicated. This work aims to build neural network models to correlate the cutting parameters, namely cutting speed, depth of cut and feed rate, to the machining force and chip thickness ratio. The turning process was performed on high strength aluminum alloy 7075-T6. Three radial basis neural networks are constructed for cutting force, passive force, and feed force. In addition, a radial basis network is constructed to model the chip thickness ratio. The inputs to all networks are cutting speed, depth of cut, and feed rate. All networks performances (outputs) for all machining force components (cutting force, passive force and feed force) showed perfect match with the experimental data and the calculated correlation coefficients were equal to one. The built network for the chip thickness ratio is giving correlation coefficient equal one too, when its output compared with the experimental results. These networks (models) are used to optimize the cutting parameters that produce the lowest machining force and chip thickness ratio. The models showed that the optimum machining force was (240.46 N) which can be produced when the cutting speed (683 m/min), depth of cut (3.18 mm) and feed rate (0.27 mm/rev). The proposed network for the chip thickness ratio showed that the minimum chip thickness is (1.21), which is at cutting speed (683 m/min), depth of cut (3.18 mm) and feed rate (0.17 mm/rev).

The book is intended to be helpful, with straightforward and easy to make recipes that everyone can manage with the equipment they have available. It is split into four sections including a seasonal vegetable guide, kettle recipes, toastie maker recipes and microwave recipes. Every recipe has a full breakdown of the cost of the ingredients, tells the user how long it will take to make the recipe, and gives an idea of where you can buy the ingredients for the recipe. All recipes have a picture to show what the final product looks like.
On the Reusability of Data Cleaning Workflows
Authors: Li Lan , LudÃ¤scher Bertram
Published: September 2022

The goal of data cleaning is to make data fit for purpose, i.e., to improve data quality, through updates and data transformations, such that downstream analyses can be conducted and lead to trustworthy results. A transparent and reusable data cleaning workflow can save time and effort through automation, and make subsequent data cleaning on new data less errorprone. However, reusability of data cleaning workflows has received little to no attention in the research community. We identify some challenges and opportunities for reusing data cleaning workflows. We present a high-level conceptual model to clarify what we mean by reusability and propose ways to improve reusability along different dimensions. We use the opportunity of presenting at IDCC to invite the community to share their uses cases, experiences, and desiderata for the reuse of data cleaning workflows and recipes in order to foster new collaborations and guide future work.
Determination of rational operating parameters of vibroimpact screen
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Sizikov Valentin
Published: September 2022

The paper deals with the problem of vibroimpact screen operating regimes selection for the regime of anti-phase oscillations of its elements. The criteria of effective screen operation accepted are impact impulse transferred to sieve from vibroimpact lattice and sieve double amplitude, which provide effective regimes of sieve cleaning from clogging particles and maintenance of preset sieve oscillations regime for support of technological parameters of material screening. Using the developed mathematical model and program the computational experiment was conducted for operating oscillation frequency range from 105 rad/s to 160 rad/s and adjustment gap between vibroimpact lattice and sieve for operating range from 0 to 5,5 mm. Influences of oscillation frequency and adjustment gap on impact impulse transferred to sieve and sieve double amplitude are obtained in the form of regression equations. On its base the recommendations for determining effective operating regimes of vibroimpact screen are offered. Obtained regularities explain nonlinear behavior of two-mass vibroimpulse oscillating system according to its operating parameters changing and show principal opportunities of system control. Also obtained results could find an application in screen operating regimes adjustment during commissioning and start-up operation and screen operation period, and could decrease labor costs and fasten the procedure of rational screen operating parameters searching.
A review of ‘Science Communication Practice in China’
Authors: Medvecky Fabien
Published: September 2022

‘Science Communication Practice in China’ is a book that does two things. One very intentional, one less so. Intentionally, it presents the state of science communication and popularisation in China with a strong focus on the historical and policy context this is embedded in. Less (or possibly un-)intentionally, it makes explicit both its assumptions about what science communication should aim for and how it should go about its business, as well as forcing the reader to acknowledge their own assumptions of the role and place of science communication.

Akulturasi Hukum Islam & Hukum Adat Perkawinan Matrilokal Di Madura
Authors: Saâ€™dan Masthuriyah
Published: September 2022

Perkawinan di Madura mengikuti pola residensi matrilokal, artinya pasca menikah suami ikut ke rumah istri (mertua), laki-laki dianggap sebagai tamu di rumah keluarga istri. Meski demikian, pola kekerabatan di Madura bukan Matrilineal, melainkan bilateral. Begitu juga dalam hal otoritas kepemimpinan dalam unit keluarga, laki-laki memiliki kendali penuh dalam tanggung jawab nafakah lahir bathin dan perkembangan kelanjutan hidup istri dan anak-anaknya. Hegemoni kuasa laki-laki atas perempuan di Madura tercermin pada pola hunian tanian lanjheng. Juga perkawinan matrilokal di Madura adalah hasil dari kolaborasi antara hukum adat di Madura dengan hukum Islam sebagai hukum ajaran agama mayoritas di Madura. Karena sikap biasa gender ini menimbulkan banyak ketidak adilan untuk perempuan, maka dibutuhkan prespektif baru yang adil gender dengan cara menggeser hegemoni patriarkhi menuju relasi yang setara antara laki-laki dan perempuan.

Authors: Napalkova Anastasiya Alekseevna , Loboda Anastasiya Anatol'evna
Published: September 2022

Customer focus in the enterprise management system is an important condition for its functioning and a key success factor in a competitive environment. The problem of customer focus from the point of view of the process approach remains insufficiently studied. There are explored the approaches to the customer focus of an enterprise by using the method of content analysis. The basic postulates of the concept of customer relationship management are considered, which is aimed at optimizing the current and future consumer value for the company and ensuring a long-term competitive advantage through the optimal provision of value to the customer. The strategic role of CRM in company management is studied, which combines the potential of intelligent technologies and relationship marketing strategies to maintain profitable, long-term relationships with customers. The functions of CRM - systems in ensuring the enterprise’s customer orientation are highlighted. It has been proven that the development and widespread use of digital technologies can provide the necessary personalization to ensure a customer-oriented enterprise. It is noted that the digital transformation of business affects the intensive development of the company, providing maximum customer value and customer focus. In the context of omnichannel consumer behavior the companies need to be more flexible than before in order to meet consumer expectations and ensure a satisfying consumer experience. The general components of developing the enterprise’s customer orientation concept in the context of digital business transformation are presented. A model of a client-oriented enterprise based on business processes is proposed, which reflects the main important processes of creating the client capital aimed at effective interaction with customer in touchpoints.
The Impact of COVID on Productivity and Potential Output
Authors:   INSEAD, Fernald John ,   Federal Reserve Bank of San Francisco, Li Huiyu ,   Federal Reserve Bank of San Francisco
Published: September 2022

The U.S. economy came into the pandemic, and looks likely to leave it, on a slow-growth path. The near- term level of potential output has fallen because of shortfalls in labor that should reverse over time. Labor productivity, to a surprising degree, has followed an accelerated version of its Great Recession path with initially strong growth followed by weak growth. But, as of mid-2022, it appears that the overall level of labor and total factor productivity are only modestly affected. The sign of the effect depends on whether we use the strong income-side measures of pandemic output growth or the much weaker expenditure-side measures. There is considerable heterogeneity across industries. We can explain some but not all of the heterogeneity through industry differences in cyclical utilization and off-the-clock hours worked. After accounting for these factors, industries where it is easy to work from home have grown somewhat faster than they did pre-pandemic. In contrast, industries where it is hard to work from home have performed extremely poorly.
Effects of Varying Injector Opening Pressure on the Performance of a B20 JOME Biodiesel Fueled Diesel Engine
Authors: Jaichandar Sriramulu , Samuelraj D. , Kumar M. Sathish
Published: September 2022

The present work examines the influence of Injector Opening Pressure (IOP) on Jatropha oil fueled Compression Ignition (CI) engine. A Direct Injection (DI) type diesel engine was tested with a blend of 20% Jatropha Oil Methyl Ester (JOME) with 80% diesel (B20) on volume basis. The engine was run on four different injector opening pressures viz. 190, 210, 220 and 230 bar along with standard IOP of 200 bar. For all IOPs, performance considerations like brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), combustion factors such as cylinder pressure and ignition delay and emission issues such as CO, UBHC, smoke opacity and oxides of nitrogen (NOx) were investigated. From the experimental examinations it was observed that IOP of 220 bar showed improvement in terms of BTE and BSFC by about 2.3% and 4.4%. Considerable enhancement in reduction of emission levels particularly for CO, UBHC and smoke were also observed for increased IOP of 220bar by about 26.4%, 12.96% and 3.4% respectively, compared to the engine operated at standard IOP of 200 bar. However, NOx emission level was deteriorated compared to normal IOP. It was also found that increasing the IOP, lowered ignition delay and increased the in-cylinder pressure.

Published: September 2022

Exhaust emissions emitted from spark ignition engines cause air pollution, human health hazards and ecological imbalance. Hence, effective curtail of these is an essential task. For this, an experimental evaluation was carried out on emissions and performance characteristics of the four-stroke three-cylinder Maruthi engine at varied brake power. Three different techniques, initially the exhaust gas recirculation (EGR) system was coupled to the test engine and varied from 0 to 10% for estimation of optimal value. Secondly, the provision of the catalytic converter with the copper as a catalyst and finally by the air injection mechanism of 60 l/m into the catalytic converter is executed and evaluated for optimum emission reduction. Also, the combined effect of these techniques on the characteristics was analysed. From the results, it was found that up to an EGR rate of 5%, an enhancement of 2% in brake thermal efficiency and a reduction of 9.5% in brake specific fuel consumption, 21% in carbon monoxide (CO), 19% in un-burnt hydrocarbon (UHC) and 29% in NOx emissions and a further increase in the EGR rate causes performance deterioration. The NOx emissions decreased by 44% at 7% of EGR. The catalytic converter setup alone decreased CO and UHC by 40% and by application of air injection it was 60%. The CO& UHC emissions decreased by 54% &52% respectively at 7% EGR rate combined with the catalytic converter and air injection mechanism.

The system programme codes is one of the issue need to confront consequent since there are various sorts of calculation that are in the same field, however has unmistakable of use. This project focuses on how to measure distances using binocular vision. The main objective is to evaluate the binocular vision system by calculating the distance of objects in real environment. Furthermore, the project proposes a new program algorithm for binocular vision system to work, in order to identify distance of an object with a basic equation has been derived and set in the designed algorithm. The setting environment are set to single and multi-objects measured, object in environment and changes of degree of bright light. Evaluation of the system shows the detected distances are consistence and the data were recorded. The value of the distances detected are then compared with the real environment distances.

Quality Green Lean Energy Leadership Management System is a combination of Green Management System (EMS), Total Quality Management System (TQM) and Lean Manufacturing (LM) with the Energy Management System (EnMS) policy. Therefore, a survey questionnaire was developed and distributed to 30 highly active and recommended automotive vendors in Malaysia by Malaysian Automotive Institute (MAI) and the data was analyzed by using Statistical Package for the Social Sciences (SPSS) v.19. From the survey, it was found that most vendors have been practicing TQM, LM and EMS due to customer requirement, however, there are only a few vendors that are aware of Energy Management System (EnMS). However, from the survey the awareness of the EnMS is still lacking due to lack of action and commitment. In order to turn out with a system model, the implementation practices were separated into 4 classifications which are Foundation Level, Level 1, Level 2 and Level 3. The level of the practices is arranged based on the implementation level. The objective of this system is to achieve customer satisfaction, green management system and energy safety and efficiency,so that the organization can compete in the market.

This paper presents a numerical analysis of simply supported cellular steel beam (CSB) at elevated temperatures. Currently, CSB is increasingly used as the main structural element in multi-storey buildings, warehouses and any steel structures. Typical steel beams are mainly used as a dwelling load bearing capacity. CSB is one of the options to replace the former steel beam. Several advantages can be gained when adopting CSB as the main structural element in structures. However, several drawbacks have restricted the structural performance of CSB under applied load, especially under fire exposure. Fire is one of the major catastrophe that may endanger any structural steel member in a steel frame building under certain duration. It is important to reduce the member temperature induce by fire exposure to prolong the time before the CSB failed. Experimental data available in the literature review will be used to validate with numerical simulation in this research.
Fatigue Life Assessment Approaches Comparison Based on Typical Welded Joint of Chassis Frame
Authors: Starykov Maksym
Published: September 2022

There are many approaches to the durability calculation that are used in engineering practice. At the same time the existing accident studies show that the leading position is still hold by fatigue failures. This means that there is still no universal approach to fatigue problem solution, and the existing approaches have their limitations. In addition, there is lack of information about the comparison between the precision of the obtained results using different approaches. In this paper different fatigue life calculation methods, like nominal stress, hot spot stress, notch stress and fracture mechanics are used to calculate the durability of T-type welded joint. The obtained results are compared with the fatigue test ones and the approaches, which give the closest results, are found.
Large-Eddy Simulation of Unsteady Pitching Aerofoil using a Oneequation Subgrid Scale (SGS) Model based on Dynamic Procedure
Authors: Kajishima Takeo , Mohamad Firdaus
Published: September 2022

Large-Eddy Simulations (LES) for an oscillating NACA0012 aerofoil at Reynolds number 1.35 × 105 have been performed to investigate the capability of a new approach of a One-equation SGS model. The phenomena of the oscillating aerofoil at higher amplitude angle (𝛼𝑎𝑚𝑝) is believed to produce deep dynamic stall in which strong non-equilibrium turbulence could also visible. Hence, a new approach of a one-equation SGS model is proposed where the coefficient of production term in the kSGS transport equation is defined dynamically. From the simulations, the leading-edge vortex (LEV), dynamic stall vortex (DSV), shedding mechanism and trailing edge vortex (TEV) are captured in this study.

On airplanes and UAVs, a stall is something that is always attempted to avoid. Stalling can also be aided by the employment of planform wings with varying geometry. Curved wing variations are often used in UAV applications, especially at low Reynolds numbers. This study discusses stall behavior on rectangular, elliptical, semi-elliptical, and Schuemann wings. Numerical simulations were performed using the turbulent k-ω SST model using Ansys Fluent 19.1. The airfoil used in this study was Eppler 562 at Reynolds number 2.34 x 104 . The angles of attack observed were 0o , 2o , 4o , 6o , 8o , 10o ,12o , 15o , 17o , 19o , and 20o . The Schuemann wing has the best performance that is indicated by the delaying of the stall point, which is at an angle of attack α = 15o , while the rectangular wing produces the highest lift to drag ratio compared to other planform wings. The confluence of the main flow and backflow forms towards the mid-span as the angle of attack increases. The rectangular wing produces high vorticity in the wingtip area due to the tip- vortex phenomenon, while the elliptical and Schuemann wing in the leading edge area due to the geometry of the leading edge.

Published: September 2022

The vortex shedding of a turbine blade is suppressed by making a hole, connecting between the pressure side and suction side in the area of the trailing edge. Computational simulation has been done via numerical code by using Spalart–Allmaras turbulence model with Delayed Detached Eddy Simulation. The exit Reynolds number is 2.8 × 106 and the exit isentropic Mach number is 0.79. The size of the hole is 0.094D with a connecting angle of 30 degrees. The result shows that the vortex has successfully been suppressed at the turbine trailing edge and turbine wake area. The micro-hole is capable to reduce initial vortex formation which can be confirmed by the decrement of frequency peak and via observation of flow field vortex simulation.

En el estudio de los sacra saxa de la Península Ibérica se ha identificado un lecho rupestre en Ceclavín, Cáceres. Los sacra saxa son peñas asociadas a mitos y ritos mágicos procedentes de tradiciones animistas ancestrales, que permiten conocer la visión sobrenatural del paisaje sacro de los pueblos prerromanos, que ha perdurado cristianizada en ritos de magia popular considerados “supersticiones”. El lecho rupestre de Ceclavín, situado junto a un arroyo y orientadocon precisión hacia el norte, verosímilmente hacia los numina o divinidades del Más Allá, debe relacionarse con la tradición de incubatio de la Hispania Celtica, cuyos documentos se analizan junto a la tradición popular conservada en Galicia de magia curativa en lechos rupestres.
