Smooth 3D manifolds based on thin plates

This paper demonstrates a fractal system of thin plates connected with hinges. The system can be studied using the methods of the mechanics of solids with internal degrees of freedom. The structure is deployable, and initially, it is similar to a small-diameter one-dimensional manifold, which occupies significant volume after deployment. The geometry of solids is studied using the method of the moving hedron. The relationships enabling the definition of the geometry of the introduced manifolds are derived based on the Cartan structure equations. The proof substantially makes use of the fact that the fractal consists of thin plates that are not long compared to the sizes of the system. The mechanics are described for solids with rigid plastic hinges between the plates, and the hinges are made of shape memory material. Based on the ultimate load theorems, estimates are performed to specify the internal pressure that is required to deploy the package into a three-dimensional (3D) structure and the heat input needed to return the system into its initial state. Some possible applications of the smooth 3D manifolds are demonstrated.

Numerical Investigation of the Effect of Bubble-Bubble Interaction on the Power of Propagated Pressure Waves

The study of bubble dynamics, especially the interaction of bubbles, has drawn considerable attention due to its various applications in engineering and science. Meanwhile, the study of the oscillation effect of a bubble on the emitted pressure wave of another bubble in an acoustic field which has less been investigated. This issue is investigated in the present study using the coupling of Keller-Miksis and Gilmore models. The ordinary differential equations are solved using MATLAB software and Runge-Kutta forth order method with the adaptive step size control. The results show the dependence of bubbles behavior and the strength of their pressure waves on two parameters of the initial radius and the bubbles center-to-center distance. As the initial radius of the adjacent bubble grows, its effect on the other bubble increases and causes a reduction in the other bubble maximum radius, wall velocity, internal pressure, and emitted pressure wave intensity. However, increasing the initial distance of the bubbles reduces the effect of the bubbles on each other and causes their behaviors become closer to the single-bubble oscillation mode.
Implementasi Grounded Theory Untuk Menganalisis Pengaruh Fungsionalitas Media Sosial Terhadap Segmentasi Pasar UMKM di Indonesia

— Empowering SMEs in the midst of globalization and high competition has forced MSMEs to face global challenges, such as increasing innovation, developing human resources and technology, and expanding the marketing area. Social networks provide a medium for processing new innovations for SMEs such as relationships with customers, work partners and also suppliers. Business process management can assist business actors in carrying out their business activities in the face of today's challenges and global competition. This study reveals that every business process can be supported by the implementation of IT by a company. This study uses a grounded theory approach. Grounded theory studies tend to follow a structured approach. This research uses case studies of hydroponic SMEs in Indonesia, which produce the types of social media & social media functions that are often used by Indonesians. The main strength of this research is the functions of social media needed by SME actors. From the results of the study it was found that SMEs need social media functionality in 4 functions, namely: the interaction function, the marketing function, the reputation function, and the information function. SMEs in Indonesia need applications that contain these 4 functions to be able to market, sell, and interact with other people
Potential of Antioxidant Enzymes as biochemical biomarkers for glyphosate-based herbicide in Oreochromis niloticus

The current study examined the toxicity of Roundup, which is a herbicide containing glyphosate that is commonly used in agriculture, on Oreochromis niloticus, a type of freshwater fish. The researchers investigated the effectiveness of using antioxidant enzymes as biochemical biomarkers to assess the potentially toxic impact of Roundup on the fish. The sub-lethal concentration of Roundup in tilapia is 1.05 mg/l for 96 hours of exposure. The fish were exposed to sub-lethal concentration (36.8 to 46.9 mg/L) of Roundup for a period of 24, 48, 72, and 96 hours, and their antioxidant enzyme activities were measured, respectively. According to the findings, Roundup exposure led to a noticeable rise in the levels of superoxide dismutase, catalase, and peroxidase activities in both the liver and gill tissues of the fish, which suggested the occurrence of oxidative stress. These changes in antioxidant enzyme activities were concentration-dependent, suggesting that Roundup exposure can induce oxidative damage in fish. The study concluded that Roundup affects the enzymatic activity of both organs in a concentration- and time-dependent manner. Catalase and peroxidase activities were generally inhibited, while superoxide dismutase activity was affected differently depending on the organ, concentration, and time of exposure.
Feeding common carp fish on diets containing different percentages of ginger (Zingbar officinale) and its effect on the characteristics of the blood and biochemical parameters

: Common carp (Cyprinus carpio L.) were manually fed a diet supplemented with ginger powder (Zingiber officinalis) at levels (0, 6, 8, and 10) % to observe the effect of ginger powder on blood and biochemical parameters. The research was conducted in the fish laboratory of the Faculty of Animal Production /College of Agriculture and Forestry/University of Mosul. In this study 84 fish were used and distributed over 12 glass tanks with an average weight of 28 ± 1gm. The fish were fed 3 times a day at a rate of 3% of body weight for a period of 56 days. At the end of the experiment, there were significant differences (P<0.05) in the hemoglobin standard in the treatments to which ginger was added compared to the control treatment. PCV values also increased in fish fed on the added diets. Also, albumin values decreased in treatments to which ginger was added compared to the control treatment, and globulin values decreased in treatment 2 (6% ginger). There were also no significant differences in the total protein standard between the control treatment and the treatments to which ginger was added, except for the treatment which had an 8% level of ginger. The level of glucose also decreased significantly in blood of fish fed on ginger compared to the control treatment. while the values of cholesterol and triglycerides varied for the ginger treatments compared to the control treatment. Also the values of Aspartate Transaminase enzyme (AST) decreased in the treatments to which ginger was added compared to the fish fed on the control diet and Alanine Transaminase enzyme (ALT) values also decreased in all treatments that had ginger added to it compared to the control except for the fourth treatment (10% ginger), which was higher than the rest of the treatments. Feeding fish diets containing ginger lowered hemoglobin in the blood.

During the Black Lives Matter Movement, many Black activists and allies have experienced direct and indirect forms of racial trauma and violence. Previous studies have shown that membership in a racial or ethnic minority group is associated with an increased risk for developing post-traumatic stress disorder (PTSD) and mood disorders such as depression due to exposure to trauma (Lopéz et al., 2017). However, although racial trauma could lead to a diagnosis of PTSD, racial factors that contribute to the trauma are often overlooked because of the limitations in what is defined as s a traumatic event. In this paper, I will explore the issue of racial trauma and examine its role in diagnosing mental illnesses and the delivery of mental health services. To gain a deeper understanding of racial trauma, I analyzed existing studies on the history of racial trauma, its impact on mental health, and various social practices of recognition. The purpose of this study is to examine the effects of racial trauma on individuals in the Black community. How exactly have these experiences of trauma affected the mental health of Black community activists and allies? Do social factors such as stigmas influence the perception of racial trauma? Most importantly, what resources and solutions are available in addressing the interpersonal trauma that these individuals experience due to racial bias and discrimination. To answer these questions, I conducted qualitative interviews with 35 Black activists and allies who shared their experiences with protesting and their perception of mental health and racial trauma.
The art of fitting financial time series for some stock market indexes of some of the main emerging countries and for Mexico with stable Lévy Distributions

This paper presents a statistical analysis of the logarithmic fluctuations of the returns of some of the main stock market indices. Samples were analyzed considering daily data covering a period from 01/03/2000 to 09/30/2022, and adjusted to different distributions. Goodness-of-fit tests were performed to quantitatively assess the quality of the estimate. Particular attention was paid to the impact of sample size on the estimated decay of the tail of the distributions. In this study, a forceful rejection of normality was obtained. On the other hand, the null hypothesis that the logarithmic fluctuations conform to a stable alpha Lévy distribution cannot be rejected considering a significance level of 5%.
Why does accuracy assessment and validation of multi-resolution-based satellite image classification matter? A methodological discourse

This study presents a methodological discourse about how to validate the reliability of thematic maps derived from multi-resolution satellite-based image classification. Besides, the paper examines unbiased estimates of accuracy assessment using known sampling units. Landsat and spot images were used for lulc thematic layer extraction. These thematic layers together with reference data extracted from panchromatic aerial photo interpretation and ground survey were used as input datasets for accuracy assessment and validation analysis. For each lulc unit, a minimum of 50 reference samples were derived using a stratified random sampling scheme. Consequently, error matrices were generated to validate the quality of the 1973, 1995 and 2007 lulc maps. To improve sampling biases introduced due to the stratified random sampling reference data collection scheme, accuracy assessment indices including the producer’s, user’s and overall accuracy as well as Kappa coefficient of agreement were adjusted to the known areal proportion of map categories. The computed overall accuracy, corrected for bias using known marginal proportions of the 1973, 1995 and 2007 thematic layers were 88.12%, 89.95% and 92.27%, respectively. Also, 81.20%, 82.17% and 83.11% of Kappa coefficient of agreement were achieved from the 1972, 1995 and 2007 classifications, respectively. The findings show that high resolution aerial photos are good sources of reference datasets in the absence of historical ground truth data for accuracy assessment analysis and the lulc classifications fulfilled the minimum of lulc classification standards of overall accuracy and Kappa coefficient of agreement. Consequently, all the lulc classifications could be used as an input for policy options for integrated land resource management practices in the watershed studied.
Grids of stellar evolution models for asteroseismology

In this paper we present a grid of stellar evolution models, computed with an up-to-date physical description of the internal structure, using the Code d’Evolution Stellaire Adaptatif et Modulaire (CESAM). The evolutionary sequences span from the pre-main sequence to the beginning of the Red Giant Branch and cover an interval of mass typical for low and intermediate mass stars. The chemical composition (both helium and metal abundance) is the solar one. The frequencies of oscillation, computed for specific stellar models of the grid using the Porto Oscillations Code (POSC), are also provided. This work was accomplished in order to support the preparation of the CoRoT mission within the Evolution and Seismic Tools Activity (CoRoT/ESTA). On the other hand, the grid can also be used, more generally, to interpret the observational properties of either individual stars or stellar populations.

Molecular versus Morphological Identification of Fusarium spp . isolated from Egyptian corn.

Fumonisins are important mycotoxins produced mainly by Fusarium verticillioides and Fusarium proliferatum , which are associated with human esophageal cancer. In this study, 56 Fusarium isolates - from 31 field maize samples collected from Egypt, were identified using both morphological and molecular methods. The potential production of fumonisin B1 was determined using HPLC and molecular methods . The results of molecular identification showed that all Fusarium isolates belonged to F. verticillioides , based on F. verticillioides -specific primer pair Verpro-F/VERTI-R and primer pair Taqfum- 2f/Vpgen- 3R, which is specific for F. verticillioides , F. proliferatum, F. subglutinans, F. globosum and F. nygamai, while the morphological and microscopic identification of the 56 isolates showed that 54 isolates (96.4%) belonged to F. verticillioides , 1 isolate (1.8%) belonged to F. proliferatum and 1 isolate (1.8%) belonged to F. subglutinans ; showing compatibility of 96.4% with the molecular identification. Although just one corn sample from the 31 contained 9.8 mg kg -1 FB1; which considered higher than the permissible limit (3 mg kg -1 ). The HPLC analysis confirmed that about 82% of the isolates were able to produce fumonisin B1 in ranges between 1.4 to 555 mgkg -1 medium. Whereas, PCR detection indicated that all isolates were able to produce fumonisin B1. Results of this study revealed that PCR-based technique could be used to differentiate the Fusarium species from other genera of fungi as well as to identify fumonisin-producing Fusarium species .
DIGITALIZATION OF ZAKAT, INFAQ, AND SHADAQAH (ZIS) THROUGH THE USE OF QRIS (CASE STUDY: GENERATION Z)

Zakat, infaq, and shadaqah (ZIS) as social financial instruments in Islam have a role in improving the social economy of society. Research results, The BAZNAS strategy as of December 2021 notes that the total potential for zakat in 2020 has reached IDR 327.6 trillion. This potential is supported by the level of generosity of the Indonesian people is high because the majority of Muslims. Charities Aid Foundation (CAF) World Giving Index in 2021 places Indonesia in first place as the country with the most philanthropist in the world. Based on BAZNAS data in 2021, collection ZIS funds have seen an increase of 33% over 2020 in total collected Rp. 513.3 billion or an increase from the initial target. But the amount of the accumulated ZISWAF funds is not comparable to their potential reached IDR 327.6 trillion. In today's digital era, financial transactions on the ZIS instrument are an alternative solution so that the collection of ZIS funds can be maximum. A survey conducted by the Association of Internet Service Providers Indonesia (APJII) in 2021, noted that internet users in Indonesia increased by 11% from the previous year, namely from 175.4 million to 202.6 million users. This has implications for the development of e-lifestyle (lifestyle digital) in the era of society 5.0. This research aims to offer a solution utilization of the use of QRIS in raising ZIS funds in Indonesia. The Deputy Governor of Bank Indonesia stated that throughout 2021 transactions carried out using QRIS reached IDR 27.7 trillion or grew 237% (y-o-y). This study uses the critical literature review method, with review and analyze literature relevant to the research topic. Data used are primary data from surveys on generation Z and secondary data. The results of the study show that the collection of ZIS funds through the use of QRIS has an impact on increasing ZIS fundraising. So, funds ZIS can have a more significant impact in supporting poverty alleviation listed in the Sustainable Development Goals (SDGs).
Trapped modes in non-uniform elastic waveguides: asymptotic and numerical methods

Trapped modes within elastic waveguides are investigated employing asymptotic and numerical methods. The problems considered in this thesis concentrate on linear elastic waves in thickened/thinned and curved waveguides. The localised modes are propagating within some region that is characterized by a small parameter but are cut-off for geometric reasons exterior to that region, and thereafter exponentially decay with distance along the waveguide. Given this physical interpretation long wave theories become appropriate. The general approach is as follows: an asymptotic scheme is developed to analyse whether trapped modes should be expected and to obtain the frequencies at which trapped modes are excited. The asymptotic approach leads to an ordinary differential equation eigenvalue problem that encapsulates the essential physics. Then, numerical simulations based on spectral methods are performed for this reduced equation and for the full elasticity equations to validate the asymptotic scheme and demonstrate its accuracy. The thesis begins with an investigation of trapping due to thickness variations. The long-wave model for trapped modes is derived and it is shown that this model is functionally the same as that for a bent plate. Careful computations of the exact governing equations are compared with the asymptotic theory to demonstrate that the theories tie together. Different boundary conditions upon the guide walls and the importance of the sign of the group velocity are discussed in detail. Then, it is shown that boundary conditions also play a crucial role in the possible existence of trapped modes. The possibility of trapped modes is considered in nonuniform elastic/ ocean/ quantum waveguides where the guide has one wall with Dirichlet (clamped) boundary conditions and the other Neumann (stress-free) boundary conditions. For bent waveguides, with such boundary conditions, the sign of the curvature function is shown to
CEO’S CHARACTERISTICS AND CSR DISCLOSURE: EVIDENCE FROM ISLAMIC BANKS ACROSS MENA REGION

The purpose of this paper was to explore the relationship between the characteristics of the chief executive officer (CEO) and corporate social responsibility (CSR) of banks operating in the Middle East and North African (MENA) countries. The study hypotheses was tested using a multiple linear regression model by examining data from a sample of 97 Islamic banks operating in the MENA region between 2015 and 2019. The results were robustly checked and the findings indicated that both CEO’s overconfidence, experience and education appear to have a significantly positive effect on the CSR disclosure. Furthermore, the results of multiple linear regressions showed that older CEO’s have a negative and significant impact on the level of CSR disclosure. This research bridges the gap between theory and practice in many aspects. Thus, although a substantial volume of research has examined sustainable advantage, one vital aspect of CSR has been largely unexplored. This study fills this void in the literature, namely the interaction between CEO’s characteristics and CSR disclosure. An explicit CSR disclosure may improve social well-being in emerging markets
