Finite-time lag projective synchronization of delayed fractional-order quaternion-valued neural networks with parameter uncertainties
Authors: Shang Weiying , Zhang Weiwei , Zhang Hai , Zhang Hongmei , Cao Jinde , Alsaadi Fawaz E.
Published: February 2023

This paper discusses a class issue of finite-time lag projective synchronization (FTLPS) of delayed fractional-order quaternion-valued neural networks (FOQVNNs) with parameter uncertainties, which is solved by a non-decomposition method. Firstly, a new delayed FOQVNNs model with uncertain parameters is designed. Secondly, two types of feedback controller and adaptive controller without sign functions are designed in the quaternion domain. Based on the Lyapunov analysis method, the non-decomposition method is applied to replace the decomposition method that requires complex calculations, combined with some quaternion inequality techniques, to accurately estimate the settling time of FTLPS. Finally, the correctness of the obtained theoretical results is testified by a numerical simulation example.

Authors: Hetman Yuliia
Published: February 2023

Socio-political participation online is of great importance for the development of democracy, so the study of the institutionalization of online activity is extremely relevant. Given the digitalization of all spheres of life, it is advisable to study the processes of institutionalization of online activity taking into account the features of metamodern society, as well as taking into account the transformation of social values and norms. A significant role in the legitimization of online activity is played by citizens' appropriation of the public sphere, as well as its dynamic digitalization, which directly affects the expansion of public participation and involvement of a much wider audience in the socio-political process. Therefore, the article analyzes the role of the digital public sphere in the development of online activity is analyzed, the research approach to the concept of institutionalization as a whole is defined. The process of institutionalization of social and political online activity in Ukraine is also analyzed. The article also notes that the institutional infrastructure, as well as the legality of socio-political online activity, is provided by the state, but the question is whether Ukrainians accept new social requirements, rules, and norms that are formed in the conditions of digitalization of social life.

The number of cases of child abuse against parents today urges to be investigated and found a solution. Because it is lamentable and not in accordance with religious values also contrary to human rights. This paper, using the library method, will summarize several acts of child violence against parents from the last 3 years as evidence that this action is not a fabrication. The conclusion that emerges in this paper is that the prophet Muhammad PBUH in his hadith has predicted this phenomenon. Through the Hadith of Jibril, it can also be seen why acts of violence against children occur against their parents. It also can be seen that as time progresses, human morals decrease. In addition to predictions through Jibril's hadith, there are several other causes of child violence against parents such as wrong parenting and environmental factors that are not good.

Thesis. The aim of this paper is to present one of the outcomes of the Fight the Fright project. The project itself focuses on the development of adult competencies related to public speaking, self-confidence, combating fear of public speaking and interpersonal communication, using theatre techniques. It focuses on improving the competencies of adults and adult educators.

Concept. Based on their knowledge and experience, the project partners have developed educational materials to support working-age people and strengthen their competencies. It is crucial to train educators so that they can pass on this knowledge to the next person.

Results and conclusions. The project has developed two manuals. The first is a curriculum for developing public speaking in foreign languages. The second manual, below, was developed for adult educators to prepare them to deliver training related to overcoming the fear of public speaking in foreign languages. An online course on the above topics has also been developed. The project also envisages training adult educators, followed by further training for at least 15 participants by already trained educators.
Cuff width does not affect discomfort ratings immediately following isometric handgrip exercise
Authors: Spitz Robert W. , Song Jun Seob , Yamada Yujiro , Wong Vickie , Bell Zachary W. , Kataoka Ryo , Loenneke Jeremy P.
Published: February 2023

Previous work has found that wide cuffs produce greater discomfort with elbow flexion exercise than narrower cuffs. It is our hypothesis that this is due to the balling up of the biceps underneath the cuff that is more pronounced with a wider cuff. One method to test this is through an upper body exercise where there is no contraction of the biceps.

Purpose

To investigate the effects of cuff width on discomfort following isometric handgrip exercise.

Methods

One hundred participants completed this experiment. In a randomized order, the participants performed four sets of two-minute isometric handgrip contractions with thirty seconds of rest at thirty percent of their maximal voluntary contraction with a 5 and 12 cm cuff inflated to 40% of arterial occlusion pressure. Discomfort ratings (0–100) were given after the fourth set of exercise. Average force was recorded for all four sets.

Results

There was no difference in discomfort (BF10 = 0.158) [median difference (95% credible interval) −0.997 (−3.360, 1.283) arbitrary units], or in average force (BF10 = 0.132) [median difference (95% credible interval) 0.08 (−0.199, 0.372) kilograms], between cuff conditions. There did not appear to be a greater preference for either cuff. Forty people preferred the narrow cuff (BF10 = 0.325), forty people preferred the wide cuff (BF10 = 0.325), and twenty people had no preference (BF10 = 7.719).

Conclusion

Cuff width does not appear to influence discomfort or the average force produced. This provides support for our hypothesis that the shape of the muscle may interact with wider cuff sizes, leading to greater discomfort.

Published: February 2023

The effect of Ganoderma lucidum hot water extract of submerged cultivated mycelium suspensia on carbohydrate metabolism and lipid profile during fructose-induced metabolic syndrome in rats was studied. The outbred white male Wistar rats, in which metabolic syndrome was induced by consuming a 10% fructose solution instead of drinking water for 42 days, were used. After the induction of metabolic syndrome, the mycelium of G. lucidum in the form of water suspension (a dose of 1 g/kg of the animal's body weight) was administered to animals per os for 7 and 14 days. Glucose concentration was determined using the glucose oxidase method. The content of glycosylated hemoglobin in erythrocytes was determined by the colorimetric method. The concentration of triglycerides, cholesterol, high-density lipoproteins, and low-density lipoproteins in blood plasma was determined by enzymatic methods. A significant decrease in the content of glycosylated hemoglobin was established in animals with metabolic syndrome against the background of administration of the studied suspension. Under the conditions of experimental metabolic syndrome, the administration of mycelium for 7 and 14 days led to a decrease in the concentration of triglycerides by 17.8 and 44.8%, cholesterol by 10.7 and 21.3%, low-density lipoproteins by 14.8 and 28.4%, and to an increase in high-density lipoproteins concentration by 11.9 and 21.5%, compared with metabolic syndrome. The obtained results demonstrate the corrective effect of the suspension of the G. lucidum powdered mycelium on carbohydrate and lipid metabolism, which was directly proportional to the duration of administration.

The enormous amount of wastewater generated by restaurants often require some level of treatment before disposal. This is partly achieved by using synthetic coagulants with its attendant environmental risk. This study is aimed at investigating the use of Aluminium Sulphate (AS) and Moringa oleifera (MO) for treating restaurant wastewater (RW). Different doses (0, 50, 100, and 150 mg/l) of the prepared stock solution of AS and MO were applied to 1000 ml of RW collected from a University restaurant. The result showed that the treated sample pH reduced from 7.55 to 6.86 and 7.0 at an optimum dose of 150 and 50 ml for AS and MO while conductivity increased from 1.03 to 2.22 mg/l and 1.74 mg/l for AS and MO, respectively. Turbidity reduced from 44.73 mg/l to 5.20 mg/l for MO and 5.77 mg/l for AS; dissolved oxygen increased from 0.35 to 0.51 mg/l and 0.70 mg/l for MO and AS; Magnesium reduced from 21.11 to 14.77 mg/l for MO, but increased to 29.07 mg/l for AS; Zinc increased from 1.19 to 6.15 mg/l for MO and 7.10 mg/l for AS, while Calcium increased from 2.02 mg/l to 5.09 mg/l for MO, and 3.09 mg/l for AS. The MO seed extract achieved a better reduction of pH and turbidity at higher dose while no distinct trend was observed in all the parameters when AS was applied. Doses of MO seed extract can be further optimized and applied as a low cost option for RW treatment.

Published: February 2023

Purpose: To evaluate the epidemiological features of open globe injury (OGI) in a tertiary ophthalmic center in the south of Iran. Methods: The medical files of pediatric patients diagnosed with OGI between March 2014 and March 2019 were reviewed retrospectively. Demographic data, laterality, time of injury, cause of trauma, location and mechanisms, complications, and the involved tissues, visual acuity, type of operation, and antibiotic therapy were all analyzed. Data were processed using the SPSS. Results: In total, 110 eyes of 108 patients were included. Ages <7 years comprised 49.1%, 7–12 years 26.4%, and 13–18 years 24.5% of cases. Of the 108 patients, 76 (70.3%) were males. No significant difference between right versus left eyes was seen. The incidence of OGI was lowest in winter and highest in spring, and it had more prevalence on the weekends. Sharp objects were the most common cause of OGI in ages <7 years, while blunt objects, accidents and falls, and guns and fireworks were more prevalent in older children. Home was the most common place of injury overall. The most common type of injury was penetrating trauma. Upon arrival, most of the children had a visual acuity <0.1 decimal. Primary wound closure was the most prevalent type of surgery done predominantly within 24 hr from admission time. Conclusion: Ages <7 years and male gender were the most common age and sex of pediatric OGI, respectively, and sharp objects were the predominant etiology. Early management and primary repair are essential for prevention of complications such as endophthalmitis and amblyopia.

Objetivo: establecer la relación entre factores sociodemográficos y clínicos con el con­sumo de sustancias psicoactivas (SPA) en un grupo de pacientes con diagnóstico de esquizofrenia, atendidos en una institución de salud mental de la ciudad de Medellín, Colombia. Metodología: estudio observacional, retrospectivo de intención analítica, de un grupo de 268 pacientes atendidos en una institución de salud mental de Medellín, en los últi­mos seis meses del año 2021. Se identificaron factores sociodemográficos, de consumo de SPA y clínicos como tipo de medicamentos, reingresos hospitalarios y adherencia al tratamiento farmacológico. Se consideraron valores de Odds Ratio con intervalo de confianza (IC95%) y se identificaron factores asociados al consumo por medio de un modelo de regresión logística. Resultados: se identificó que el 34.7% de la muestra reporta consumo de SPA; variables clínicas asociadas, tipo de medicamentos, número de ingresos hospitalarios y adherencia al tratamiento. Se encontraron diferencias significativas en la edad entre el grupo de consumidores y no consumidores, con una mediana de edad menor para el grupo de consumidores. Se determinó que ser hombre, tener una mediana de edad de 27 años y estar desempleado representa un riesgo mayor para el consumo de SPA. Finalmente se establece que la edad, el sexo, la ocupación y la adherencia al tratamiento, podrían predecir el consumo en un 34%. Conclusiones: los pacientes jóvenes, en su mayoría hombres, con diagnóstico de es­quizofrenia, tienen mayor riesgo de consumo de SPA, lo que implica mayor riesgo de recaídas y menor adherencia al tratamiento farmacológico.

Repair of blades made of the cast high-temperature nickel alloys with the volume content of γ’-phase of 50...65% and more by fusion and built-up welding practically leads to no results. Only introduction of special methods in certain cases provides restoration of a section satisfying the blade operation conditions. Therefore, the leading foreign and domestic enterprises mainly use high-temperature soldering in vacuum with general heating to repair blades of the nozzle unit, flaps of the adjustable nozzle and other parts of the gas turbine hot pass. It becomes possible to increase performance of the permanent joints (especially the small ones) by high-temperature soldering with the lowest acceptable thermal effect on the base metal through local heating in vacuum by the arc discharge with the hollow cathode. Arc soldering in vacuum with supply of the powder composite solders to the greatest extent combines advantages of built-up welding and high-temperature soldering with the general heating. Results of metallographic studies and mechanical tests of the solder joints obtained by arc soldering in vacuum with powder composite solders on samples with imitation of the surface defects showed higher performance compared to that for joints created by high-temperature soldering in vacuum with general heating.

he last 2000 years have seen a change in the prices of silver, grain, land as well as a change in living costs,
the salary of hired labourers and police informers. The relationships between those figures have also changed and
the monetary systems are quite different nowadays. Thus, it is difficult to answer an apparently simple question:
how much is Judas’s 30 pieces of silver? An equivalent of 30 pieces of silver could be 95 zlotys, but also 46 500
zlotys (i.e. about $28 and $13 700 respectively).
However, it is obvious that this amount of money is dramatically little in comparison with the scale of betrayal of God and no sum of money would be adequate. But again: even if Judas had lacked faith in Jesus, the sum
of money was excessively small for betraying a good and innocent man by one who was chosen by that man from
the others and in whom his companions placed so much confidence. Even if Judas had realized that, it was unfortunately too late (Mt. 27: 1–5).

Use of methods and tools for an effective small and medium-sized enterprise in Szabolcs-Szatmár-Bereg county in Hungary
Authors: Nouar Dalila , Popovics Péter
Published: February 2023

Small and medium-sized enterprises form the engine of the Hungarian economy, both in terms of their number and their employment rate. Therefore, the efficient operation of this sector is in the interest of many economic actors. However, experience shows that today's SME sector still needs to develop in many ways to become efficient. This study aimed to analyze whether SMEs use the necessary methods and tools to be efficient. Planning and the development of strategy are very important methods and tools for efficient and organized work, as it defines and clarifies the direction taken by an enterprise. However, the survey and the in-depth interview showed that they are not necessarily considered important for the participating SME leaders. According to the interview, one of the reasons is that SME leaders have a better understanding of everyday tasks and their implementation than the managers of large companies. Furthermore, in most cases, the SME leader is personally involved in everyday work. This provides the advantage of having the opportunity to fully understand the enterprise, thus managing, and developing it more effectively, as he or she can intervene more flexibly, faster, and more accurately if necessary. However, due to the small size of the organization, the manager also must perform the tasks of several functions (marketing, management, finance, etc.), which require multidisciplinary knowledge and skill. In SMEs, due to their specificities, it is difficult to apply best practices in large enterprises in both management and various functions.

The biggest challenges of our time include meeting the demand growth resulting from the explosion in population growth and achieving sustainable management. In terms of food, the most significant problem is, on the one hand, that a large part of the population is hungry and, on the other hand, excessive food waste, which results not only in wasted food but also in wasted resources used for its production, transport, packaging and storage. Do to this the unconsumed food has a profoundly negative impact on the environment and the economy. There is a pressing need to prevent and reduce food waste to transition to a resource-efficient Europe. In this study, we would like to show how food waste changes in different countries, focusing on Europe. Our results show a significant discrepancy between Member States' data and where waste is generated. We find no significant correlation between GDP per capita and total food waste, but we find a moderately strong correlation between GDP per capita and restaurant waste at the point of generation.

The need for lean concepts application in the safety management of logistics processes cannot be emphasized as it can help in enhancing the flow of information and expediting processes within the supply network for improved organizational outcomes. The study investigated the application of lean management models to the safety management of logistics firms in Nigeria. The study population includes 215 employees of Manal Plant hire Ltd Nigeria. 138 employees were chosen using a purposive sampling method. A self-administered questionnaire was designed to collect the primary data from the respondents. The data collected were analyzed using the structural equation modeling (SEM) technique to test the hypotheses developed in the study. The study's findings suggest that Process and Equipment Management has a positive and significant effect on the operational efficiency and workplace safety of the studied firms; employee empowerment has a positive and significant effect on operational efficiency; technological innovation has a positive and significant effect on the operational efficiency, and that continuous improvement has a positive and significant effect on the operational efficiency and workplace safety. It is, therefore, concluded that the adoption of Lean Management has a positive and significant effect on the safety management of logistics firms. The study recommends that manufacturing, logistics, and service industries should be committed to carrying out process mapping to eliminate non-value-adding operations in production as well as logistics and ensure the effective and continuous flow of logistics operations.

Published: February 2023

Según estudios adelantados en Latinoamérica, se prevé que la prevalencia de la miopía aumentará a cifras considerables. En ese contexto, algunas hipótesis describen la función de la vitamina D en el aumento de la longitud axial. El objetivo del presente estudio es conocer la influencia de factores asociados con el desarrollo y la progresión de la miopía, como el medio ambiente y la nutrición, con el déficit de vitamina D. Se realizó dicho trabajo incluyendo revisiones de tema, ensayos clínicos y estudios comparativos, en español o inglés, que hayan sido publicados entre los años 2005 y 2018. Esta revisión se llevó a cabo con ayuda de diferentes bases de datos. Así, diversas hipótesis describen una función de la vitamina D en el crecimiento del ojo, y una se centra en la vitamina D y su relación con la dopamina. En tanto, estudios epidemiológicos sugieren que mayor cantidad de tiempo al aire libre es un factor ambiental modificable y protector para los niños frente al desarrollo de la miopía. Se evidenció una relación entre el déficit de vitamina D y el crecimiento ocular, lo cual genera miopía, desde el punto de vista de la síntesis de la vitamina D, como los factores genéticos que alteran la longitud axial ocular.

Tata guna lahan merupakan suatu bentuk pemaanfaatan atau fungsi dari perwujudan suatu bentuk penutupan lahan. Permasalahan yang terjadi pada penggunaan lahan adalah ketidakseimbangan alam yang disebabkan oleh beralih fungsinya lahan. Daerah Aliran Sungai (DAS) Tanggul menjadi salah satu DAS di daerah Jember yang terpengaruh akibat perubahan tata guna lahan. DAS Tanggul mengalami laju erosi sebesar 37.534,76 m3/tahun. Laju erosi salah satunya dipengaruhi oleh faktor vegetasi penutup lahan. Langkah untuk meminimalisir permasalahan diperlukan adanya penelitian mengenai perubahan tata guna lahan pada DAS Tanggul. Penelitian ini bertujuan untuk mengetahui perubahan tata guna lahan yang terjadi pada wilayah kajian dengan menggunakan metode remote sensing. Metode yang digunakan dilakukan dengan cara membandingkan tata guna lahan pada tahun 2001, 2009, dan 2018. Citra landsat-7 dan landsat-8 digunakan sebagai data pengindraan jarak jauh yang dapat digunakan dalam proses analisis perubahan tata guna lahan. Hasil penelitian selama rentang waktu 17 tahun yang berawal dari tahun 2001 hingga 2017 menunjukkan bahwa terjadi perubahan lahan pada DAS Tanggul. Perubahan tersebut terjadi pada kelas pemukiman mengalami peningkatan sebesar 7,5%, kelas hutan mengalami penurunan sebesar 6,76%, kelas sawah mengalamai penurunan sebesar 5,8%, kelas kebun mengalami penurunan sebesar 7,51%, dan kelas lahan terbuka mengalami peningkatan sebesar 4,05%. Oleh karena itu, pengindraan jarak jauh dapat digunakan dalam mengidentifikasi perubahan tata guna lahan yang terjadi berkala tanpa proses pemantauan langsung.

Authors: Haqiqi Risa Indhika , Ghozi Mohammad
Published: February 2023

According to SNI 03-2834-2000, concrete is a mixture of Portland cement, fine aggregate, coarse aggregate, and water with or without added materials to form a solid mass. Many studies have developed the building blocks of concrete mixtures to improve their quality and properties of concrete mixtures. In this study, lightweight brick waste from the rest of the construction project was used with a first refining process to pass a 0.3 mm sieve as a fine aggregate substitution mixture. The test object used is a cylinder with a size of 15 cm x 30 cm with variations in substitution of lightweight brick powder (SBR) 0%, 10%, 15%, 20%, and 30%. The method of calculating and testing materials and concrete specimens is guided by SNI 03-2834-2000. It was found that the substitution of SBR had a varying effect on the compressive strength of concrete. The maximum compressive strength was found at 21.44 MPa at 28 days, with an optimum SBR of 15% for fine aggregate.
