Authors: Suchendra K. R. , Sreenivasa Reddy M. , Ravikumar M.
Published: December 2022

Aluminium (Al) based composites enhance the mechanical and wear behavior by heat treatment. The quenching factors like cooling agent, cooling rate and temperature of cooling are expected to influence the hardness, tensile, and wear behavior of the Al MMCs. This research shows the outcomes of a sequence of experiments to find the wear and mechanical behavior of the Al6061-Al2O3-MoS2 hybrid composites are quenched with different quenching agents. Hardening of the developed hybrid composites was carried out at 510ºC for the time period of 2 hours. Later, the same composite samples were quenched in ice cubes and water separately. Finally, age-hardening was done at 180ºC temperature for 4 hours and then the samples were cooled under room temperature. Heat treated hybrid composites were subjected to evaluate the hardness, tensile, and wear behavior. The outcomes reveal that the heat treatment significantly enhances the wear and mechanical behavior of hybrid composites. High mechanical strength and improved wear characteristics were observed in the hybrid composites which were quenched using ice cubes. The fractured surface of the tensile test samples and the wornout surface of wear test specimens were studied using a SEM analysis.

Authors: Ghamry Asmaa , Esia Ahmed , Aboul-Nour Louay
Published: December 2022

A new technique of Layered Hollow Core Slab (LHCS) has been used to obtain a slab with an optimum weight-to-strength ratio. Specimens with a 90 mm top layer of High Strength Concrete (HSC) and a 90 mm bottom layer of Lightweight Aggregate Concrete (LWAC) were examined. Nine full-scale slabs with dimensions of 1600* 450* 180 mm were tested under a 4-point loading test. The %core, a/d, RFT ratio, and connection method were the different studied parameters. A push-out test was conducted on triplet specimens to study the bond strength at the interface between HSC jacket and LWAC cubes using bond agent material or shear dowels, or without treatment, to determine which method of them is suitable for connecting the two layers of the tested slabs. Load, deflection, ductility, strain, crack pattern, and mode of failure were studied. The results indicate that ultimate strength is enhanced with decreasing a/d and %core and with an increasing RFT ratio of the LHCS specimens. Using shear dowels ensures an efficient bond between the two layers of the tested slabs. ANSYS program used for modelling the slab. The numerical study accepted the experimental data with a variation of less than 10% for all slabs.

Authors: Wutschka Karsten , Lossen Karin
Published: December 2022

A variety of reform and development efforts in the German educational system, especially the extension of the school day, going along with an increasing autonomy of individual schools and extending demands on teachers led to growing interest in business science concepts being applied in the field of school development research. A main emphasis lies in the commitment of teachers who are responsible for the implementation and the success of these reforms. The aim of this paper is to identify reasons that lead to a high level of commitment of the teaching staff with a focus on German all-day schools. The intended results will be obtained by a structural equation model based on the information provided by 649 primary all-day school teachers. In addition to the relationships with other actors in the school, which are summarised under the heading of school culture, variables relating to the personalities of the teachers can be identified as predictive.

Bengali Isolated Speech Recognition Using Artificial Neural Network
Authors: Noman Abdullah , Cheng Xinmin
Published: December 2022

This research has developed a simple and efficient algorithm for Bangla speech recognition using an artificial neural network. This supervised learning model consists of four major phases: collecting audio samples, conversion into frequency domain & filtering, normalization, and applying the back propagation algorithm to train the artificial neural network. Proper filtering has granted higher noise immunity and has decreased the number of elements in the input layer of the neural network. Thus, the overall processing speed is increased. The audio samples for this research have been collected through a digital microphone, and the complete model is illustrated using GNU Octave. Although this research focuses on the Bangla language, this model can be applied to any other language.

Published: December 2022

The multi-strip ionization chamber functions as a location and dosage monitor for the Compact LAser Plasma Accelerator II (CLAPA II) beam delivery system, allowing laser pulse beam diagnostics. The properties of the planned ionization chamber were studied using Boag’s theory and Monte Carlo simulation in this research, and the energy loss and gain of 40 MeV–230 MeV proton beams in the parallel plate ionization chamber were simulated by SRIM tools and FLUKA program. The effects of various working gases on proton beam energy loss are explored, and some reference opinions are supplied for later working gas selection. The collecting efficiency of the ionization chamber under various deviations was determined using Boag’s theory. The findings reveal that when the ionization chamber air gap is 7mm and the bias voltage is over 1000V, the ionization chamber’s secondary particle collection efficiency may reach more than 90%. When the proton beam intensity is 1pA, and the gain of the ionization chamber is calculated, the detector’s output current may reach the order of 6 nA.

Authors: Feng Min , Chang Heke , Ma Xiaoxue
Published: December 2022

The support generation technique in some rapid prototyping manufacturing process plays an important role in fabricating parts of overhang geometry structures and guaranteeing the part fabrication process smoothly. A new robust and automated support generation method is proposed based on slice in this paper. During the support generation process, the self-support of part and the self-support of the support structure itself are designed to save support material. Furthermore, the different contour offsetting method corresponding to different toolpath generation method (offset toolpath generation and Zigzag toolpath generation) is also proposed to separate the part and the support structure so that the support structure can be removed easily.

Published: December 2022

Higher order modulations are the key elements to the throughput and spectral efficiency increase, especially important for the limited bandwidth scenarios. In this paper, we present a detailed analysis of the 256-QAM signal demodulation performance for the novel sidelink (SL) mode of the 5G NR communication systems. The performance is frequency offset (CFO). It was shown that the CFO has critical impact on the system performance, along with channel mobility. The simple and effective CFO studied in the non-stationary, frequency selective channel in the presence of the carrier compensation algorithm based on the slot-by-slot time-domain signal processing is proposed and investigated. Obtained simulation results have shown the feasibility of the 256-QAM modulation in applications to the main 3GPP sidelink scenarios and parameters, with the proposed CFO compensation method applied even in the case of significant user mobility.

Folk Art in the Poetics of V. M. Shukshin
Authors:   Altai State Institute of Culture, Moskovkina Evgenia
Published: December 2022

The article gives the review of various aspects of folk art functioning as artistic features of V. M. Shukshin's prose. The universal pictorial and allegorical means of Shukshin, covering the labor, everyday, festive forms of Russian national culture, is a folk song. Decorative and applied art as an ekphrastic element forms an additional imaginative system in the writer's aesthetic system. Dance usually serves as a means of psychological analysis: a sign of the inner conflict of the character, a reflex of his existential experience, a marker of a catastrophic world perception. The buffoonery of Shukshin's characters goes back to the tradition of foolishness and Skomorokhs clowning and refers to the national problem of searching for a spiritual ideal, the sacred manner of condemnation / blessing through laughter.

Hypothyroidism is one of the most prevalent endocrine disorders, second only to diabetes. Hypothyroidism diagnosis can be difficult in view of its varied and non-specific symptoms. The reason is that thyroid hormones affect virtually every organ system in the body. At the same time, the severity of thyroid hormone deficiency may vary and does not always correlate with the changes in laboratory testing results. Clinical presentation of patients with hypothyroidism may include multiple symptoms and, as a result, it can be difficult to diagnose this disorder, especially in elderly and polymorbid individuals. In some patients, the prevailing symptoms indicate that only a particular system is affected. Thus, there are diseases known as the "masks" of hypothyroidism, and this review is focused on their clinical manifestations. Conditions that may be running under the "mask" of hypothyroidism include diastolic hypertension, dyslipidemia, hydropericardium, chronic constipation, biliary lithiasis, polyarthritis, alopecia, onycholysis, depression, dysfunctional uterine bleeding, infertility, anemia, etc. Due to a variety of clinical signs and symptoms, a patient with hypothyroidism may get an appointment with any medical specialist or receive a follow-up care provided in parallel by multiple specialists. Physicians should be aware of potential hypothyroidism and specific effects of the underactive thyroid on patient’s organs and systems. It is necessary to obtain a thorough medical history about comorbidities which would help to figure out that hypothyroidism is the cause of co-occurring conditions.

Over the past decades it has become obvious that the prevalence of obesity and vitamin D deficiency is considered epidemic both in individual countries and worldwide. Pediatric obesity is a global problem. Regarding vitamin D, in addition to its role in bone health and calcium and phosphorus metabolism, its role in immune functions and in decreasing the risk of chronic illnesses has been considered. Vitamin D deficiency and excess body fat have mutual negative effects, resulting from metabolic processes that generate accumulation of inactive forms and decreased vitamin D bioavailability, in addition to decreased tissue secretion and sensitivity to insulin. As regards the supplementation of vitamin D in schoolchildren, especially in the risk groups which include obese adolescents, its doses should be higher than those routinely recommended for the prevention of hypovitaminosis D in the general population. It is necessary to include obese patients in a specific high- risk group of vitamin D deficiency and measure their blood serum 25(OH)D level. In case of vitamin D insufficiency or deficiency it is essential to use high-dose cholecalciferol. However, one should remember that just losing a greater than 5% of baseline weight may improve vitamin D status in obese patients KEYWORDS: obesity, children, adolescents, excess body weight, vitamin D deficiency, vitamin D, cholecalciferol.

Authors: Kelly Clive , Kelly Carolyn , Taylor Rachael , Gullon-Scott Fiona
Published: December 2022

Attention-deficit/hyperactivity disorder (ADHD) has been under-recognised and under-diagnosed in females until recently. As a result, females often navigate years of symptoms without appropriate support, sometimes contributing to adverse outcomes for them and for those who are close to them. This perspective explores the relationship between ADHD and early life trauma and examines the consequences of this combination for females in their later lives with regards to mental and physical health, along with social function. We discuss the increased risks of self-harm and of criminal behaviour associated with female ADHD and offer some suggestions as to how these risks can be mitigated in the future.

Background: Fish tapeworms of the genus Diphyllobothrium are pseudophyllidean cestodes transmitted through the consumption of raw or inadequately cooked fish. Objective: The current systematic review and meta-analysis aim to estimate the global prevalence of Diphyllobothrium in dogs and cats based on published literature. Methods: Multiple English databases (PubMed, Scopus, ProQuest, Web of Science, and Google Scholar) were explored for relevant papers published until December 2021. Findings: Among the 37 studies that were included, 32 documented Diphyllobothrium infection in dogs and five in cats. The pooled prevalence (95% confidence interval) was 0.060% (0.030%-0.100%). The analysis based on country showed that the highest pooled prevalence in dogs and cats was observed in Bangladesh (0.250%, 0.149%-0.366%) and Indonesia (0.254%, 0.182%-0.333%), respectively. Based on the continent, Africa (0.109%, 0.017%-0.264%) and Asia (0.060%, 0%-0.345%) were the most common regions for infection in dogs and cats, respectively. Among different diagnostic methods, the highest pooled prevalence was related to molecular (0.661%, 0.573%-0.743%) and parasitological techniques (0.041%, 0%-0.217%) for dogs and cats’ studies, respectively. Conclusion: The findings show the importance of establishing a prevention and control measure focused on improving regular deworming and enhancing awareness of parasitic zoonotic diseases to minimize the transmission risk.

Background: Prostate cancer (PCa), as the fifth leading cause of death, is the second most common cancer diagnosis in men worldwide. Human papillomavirus (HPV) can potentially contribute to PCa development and chronic inflammation. HPV infection leads to malignant and benign lesions in the genital areas of men and women. The data on the role of HPV in PCa development is contradictory. Objective: This study aims to investigate the frequency of HPV in PCa samples in hospitals in Tabriz City, Iran. Methods: This study was conducted in a cross-sectional descriptive manner. Paraffin tissue blocks including 50 patients with primary prostate adenocarcinoma and 50 patients with benign prostatic hyperplasia (BPH) were selected from Tabriz hospitals. All samples were examined for the presence of HPV16/18 by the polymerase chain reaction (PCR) method. Findings: 3 out of 50 PCa patients are infected with HPV18. None of the benign and malignant prostate samples are infected with HPV 16. Therefore, in our study, no connection exists between HPV and PCa. The Mean±SD age of HPV positive samples was 61.33±11.50 years. Conclusion: The result of this research does not support the role of HPV in the development of PCa. Therefore, additional studies are necessary to clarify the possible role of HPV in prostate carcinogenesis.

The purpose of the study is to develop algorithm for planning the need in medical care provided in out-patient conditions to elderly groups of population based on mathematical modeling methods. Research materials and methods. As a source of information, data on cases of medical care provided to the population of elderly age groups (60 years and older) were used. The probability of access was studied in each one-year age interval, starting from the age of 60 years. The principle of mathematical modeling was based on functional approach applying algebraic functions by least squares method (regression analysis). The final choice of mathematical model was made in favor of mathematical function having largest value of approximation coefficient. The degree of influence of analyzed variable “age” was evaluated by residual variance calculation.It is established that overall need for out-patient care is higher in women. The maximum consumption in both women and men falls on the age of 76 years. After this age, frequency of visits decreases regardless of gender. Minimal levels of need are observed in the oldest age groups (95-100 and older). The variability of the indicator is higher in men, both at the area of need increasing and at the stage of need decreasing. The existence of common mechanisms and factors underlying the formation of the need for out-patient care confirms the use of the identical functions in modeling process. The character of modeling function has no gender differences. The age dynamics is described optimally by polynomial functions. The proposed models of age dynamics of out-patient visit rates of representatives of elder age groups in more than 90% describe existing fluctuations using non-smoothed data.

Published: December 2022

Objective: To evaluate the physiological development of red Anthurium andreanum L. var. Tropical in three in vitro culture systems: semi-solid, partial immersion and RITA® bioreactor.
Design / methodology / approach: A completely randomized design with three treatments, semi-solid medium, partial immersion and RITA® bioreactor, and four repetitions each was used. Vitroplants of anthurium were selected with a size of 0.5 cm from the stem to the highest leaf, with three leaves in each specimen. Morphometric, chlorophyll content and hormone content analyses were carried out after 60 days of sowing. Analysis of variance and means comparison tests were performed on the data obtained through Kruskal-Wallis and Tukey, respectively, using the statistical software R-STUDIO.
Results: The highest shoot rate and root length were obtained in partial immersion; however, the number of leaves, shoots and root multiplication did not show differences with the RITA® bioreactors. The highest concentration of chlorophylls and indole acetic acid was observed when using RITA® bioreactors.
Study limitations / implications: The results are favorable for the in vitro production of anthurium, although the use of RITA® bioreactors for commercial production is a high cost in the initial investment.
Findings / conclusions: With the results obtained, it is considered that the RITA® bioreactors obtained the best results for the production of anthurium, followed by the partial immersion system. This is due to the liquid medium and better gas exchange, which favors the development of plants

Published: December 2022

Objective: To evaluate the behavior of the Paula poinsettia variety (Euphorbia pulcherrima Willd. ex Klotzsch) and to describe its characteristics, based on the guidelines established by the International Union for the Protection of New Varieties of Plants (UPOV).
Design/Methodology/Approach: The genetic improvement included hybridization and selection techniques. To promote compaction and greater branching, it was grafted on a commercial variety. The cuttings obtained gave rise to the Paula variety (Euphorbia pulcherrima Willd. ex Klotzsch), which was described in 2020, based on the Guidelines for the Conduct of Tests for Distinctness, Uniformity and Stability of the International Union for the Protection of New Varieties of Plants. A completely randomized experimental design with 10 replications was used. Vegetative and bract characteristics were recorded and an analysis of variance was applied, as well as a Tukey’s mean comparison test (P≤ 0.05).
Results: The Paula variety is medium-sized and has a wide breadth and medium branching. It is pale green in the middle third of the stem. It has oval-shaped, long, and broad leaves of the same medium-intensity color, and a wedge-shaped base. It has a long petiole with a pale green upper side. This variety also has many elliptical red bracts of medium length and narrow width. Compared to other INIFAP varieties, the vegetative and bract characteristics of Paula presented statistical differences.
Study Limitations/Implications: The commercial production of poinsettia is carried out through asexual propagation. The mother plant is kept in a vegetative state, through comprehensive and intensive management, preventing its flowering and obtaining a continuum of propagation material.
Findings/Conclusions: Paula has an intermediate cycle, with quality and competitive size, branching, and color of the bract (red). It can satisfy the taste and preference of consumers in the domestic and even foreign markets
