Authors: Khaitan Manish , Gadani Riddhish , Pokharel Koshish Nandan
Published: June 2022

Context:

Bariatric surgery is an effective method in inducing significant weight loss in patients suffering from obesity. Despite the strong evidence on its clinical effects, the data on its mid- and long-term follow-ups and durability are limited. This study is to evaluate the impact of bariatric surgical procedures on weight loss and resolution of comorbidities after surgery.

Subjects and Methods:

This was a retrospective, single-center cohort study including 1468 participants in whom laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass, one-anastomosis gastric bypass, and balloon were performed between 2010 and 2019. Standardized weight loss measures were compared using an analysis of covariance.

Results:

The mean (standard deviation) age of patients involved in this study is 43.41 ± 12.09 years with a preoperative weight and body mass index (BMI) of 117.23 ± 23.027 and 44.93 ± 8.02, respectively. The mean follow-up period is 2.9 years (0.83–9 years). Patients reported a mean percentage total weight loss (%TWL) of 8.1 ± 15.66%, percentage excess weight loss (%EWL) of 18.92 ± 40.56, and excess BMI loss of 18.38 ± 42.7 at the follow-up point of 9 years. The remission of diabetes was significantly improved by 17%. 0.89% of patients adhered to follow-up visits till the end of the study.

Conclusions:

Bariatric surgery demonstrated a beneficial association resulting in substantial weight loss and remission of diabetes. Further large, multi-site cohort studies on Indian population are needed to substantiate the evidence.

Authors: Das Sujit , Shergill S. S.
Published: June 2022

Background:

This hospital-based study was done to estimate the prevalence of uncorrected refractive errors in adults attending to our outpatient department (OPD).

Aims and Objectives:

1. To estimate the prevalence of uncorrected refractive errors in adults attending to our OPD. 2. Effects of uncorrected refractive errors on education, social life, job, psychological impact.

Materials and Methods:

In this hospital-based retrospective study, 570 refractive error patients above 18 years of age were included. All known cases of refractive error, not using glasses, were also included in this study. As per the WHO criteria, visual acuity <6/18 of Snellen visual acuity chart was taken as visually impaired while legal blindness was defined as visual acuity of 6/60 or less. Those who had ocular or any kind of systemic illness were excluded from this study. Manual retinoscopy followed by subjective verification, detailed slit lamp examination, and dilated fundus evaluation was done in all cases at the time of presentation. Postmydriatic refraction was mandatory in all who were below 21 years of age. All statistical analysis later on conducted in SPSS version 27 retrospectively.

Results:

Out of 570 patients with refractive error analyzed, 55.81% (N = 317) were found males and 44.19% (N = 251) were females. Refractive error was 50.18% (N = 285) among Hindu population whereas in the Muslim population, it was found 49.82% (N = 283). Refractive error was mostly encountered in students (46.65%, N = 265) followed by housewives (31.87%, N = 181). The most common cause of hospital visit was headache (71.48%, N = 406). The most common refractive error was compound myopic astigmatism (43.56%, N = 248). The prevalence of refractive error was 3.8% with a legal blindness of 39.40% (N = 99) in male and 37.10% (N = 118) in female. A total of 435 (76.58%) patients were freshly diagnosed in our study. A total of 20.25% (N = 115) patients refused to wear glasses because of social factors. A total of 2.10% (N = 12) patients were rejected for various jobs, whereas among 10.56% (N = 60) of cases, refractive error had the social and psychological effect in their life. Poor performance in education was found among 11.27% (N = 64) of cases.

Conclusions:

Adult screening for uncorrected refractive errors should be incorporated into the health-care system, especially for housewives, and always wearing a glass in cases of refractive error should be encouraged and campaigned.

Published: June 2022

ABSTRACT

Nocardia species are branching filaments of gram-positive bacteria that are omnipresent in soil and water. Sixteen species of Nocardia have been implicated in human infections. Nocardia infections commonly arise in the immunocompromised states including organ transplants, leukemia, HIV, steroid abuse, and autoimmune disease. Our patient, a 13-year-old male, reported to the out-patient department with chief complaints of right-sided pleuritic chest pain, cough, fever, shortness of breath, and cervical lymphadenopathy for 2 months. His computed tomography thorax scan showed a right upper lobe dense consolidation, aspiration cytology of which was inconclusive. Bronchoalveolar lavage revealed nocardiosis, with no intracranial involvement. He was treated with appropriate antibiotics and achieved significant improvement. The case is being reported as it is a rare infection in an immunocompetent adolescent.
Existence and regularity of weak solutions for a fluid interacting with a non-linear shell in three dimensions
Authors: Muha Boris , Schwarzacher Sebastian
Published: June 2022

We study the unsteady incompressible Navier–Stokes equations in three dimensions
interacting with a non-linear flexible shell of Koiter type. This leads to a coupled system of nonlinear
PDEs where the moving part of the boundary is an unknown of the problem. The known
existence theory for weak solutions is extended to non-linear Koiter shell models. We introduce
a priori estimates that reveal higher regularity of the shell displacement beyond energy estimates.
These are essential for non-linear Koiter shell models, since such shell models are non-convex (with
respect to terms of highest order). The estimates are obtained by introducing new analytical tools
that allow dissipative effects of the fluid to be exploited for the (non-dissipative) solid. The regularity
result depends on the geometric constitution alone and is independent of the approximation procedure;
hence it holds for arbitrary weak solutions. The developed tools are further used to introduce
a generalized Aubin–Lions-type compactness result suitable for fluid–structure interactions.

Published: June 2022

A 3-week study was carried out to determine the prevalence of gastro-intestinal helminths in slaughtered pigs at Bodija Abattoir, Ibadan. Five faecal samples per day were collected for 21 days (105 samples) from the rectum of slaughtered pigs, stored in sterile container, labeled appropriately and then transported in a flask with ice pack to the parasitology laboratory of the department of veterinary parasitology and microbiology, University of Ibadan, Ibadan, where they were preserved in 10 % formalin before processing for laboratory analysis. Formalin-ether sedimentation/floatation method was used for identification of the gastrointestinal parasites. The results showed overall prevalence of 62.85 % with the presence of four nematodes (Ascaris suum, Oesophagostomum spp, Metastrongyloides spp and Strongyloides spp) and one protozoan (Isospora spp). Ascaris suum (25.71 %) was the most prevalent, followed by Oesophagostomum spp and Isospora spp (14.29 % each), Metastrongyloides spp (5.71 %) whereas the least was Strongyloides spp (2.86 %) with mean eggs per gram (EPG) of 640±5.23, 500±1.06, 2190±2.34, 400±1.76 and 670±0.23 respectively. With regards to sex, sows had greater prevalence of 63.83 % as opposed to boars with 62.07 % though not significantly different (p>0.05). It can be concluded that there was high prevalence of gastro-intestinal helminthes in the study area. Therefore, strict sanitation and improved management practices as well as quarterly broad spectrum anthelminthics to be administered to the pigs are recommended
Establishment of criminal/profile DNA database and use of forensic intelligence to combat nationwide insecurity issues in Nigeria
Authors: Awofisayo Oladoja Abosade , Eseyin Olorunfemi Abraham
Published: June 2022

Criminal activity is on the rise in Nigeria. The nefarious activity of bandits is on the increase with kidnapping of students and attack on farmers. This creates fear in the terrorized communities. Armed robbery as well as rape of citizens going about their normal duties is also on the increase. The road is becoming increasingly unsafe for the citizenry as well as government officials. The government has mandated individuals to register in the National Identification Number NIN which is linked to the Bank Verification Number (BVN) (a database established to curb crime in the banking sector) and the Subscriber Identity module (SIM). The Establishment of such databases is pertinent however the NIN, BVN, SIM-NIN linkage and fingerprints may not be sufficient in solving criminal cases without DNA profiling of convicted individuals, establishment of forensic laboratories and the creation of criminal DNA profile database CRODER – a Criminal offender DNA Exert Repertoire. The role of DNA profiling as an additional measure is to keep a record of all convicted individuals and the CRODER will be an additional useful measure in profiling criminals and individuals can be adopted as a forensic tool in addition to the captured databases of NIN, BVN and NIN-SIM and will be on the watch list of security operatives. The CRODER forensic tool can be done stepwise by availability of an emergency number to dial for emergency, a dispatch personnel to respond to the call, and vigilante groups or other adhoc security officer in the vicinity of the emergency call to get to the vicinity and preserve the crime scene environment for investigators and detectives to work on. CRODER Forensic tool can then be adopted to solve the crime. Offenders trying to escape enroute the airport, can be checked via CRODER and fingerprint compared and matched with the collection in the database. The CRODER may be a necessary stride to bring kidnappers, bandits, and armed robbers to book in record time and curb the rise in criminal activity, insurgency, banditry, and insecurity in general. If properly done, Nigeria will be a haven for citizens and would-be investors.
Effect of temperature on the postembryonic stages and adults of the blowfly, chrysomya chloropyga (diptera: calliphoridae)
Authors: Ajayi A. A. , Salawu B. O. , Muse W. A.
Published: June 2022

Chrysomya chloropyga biology was studied under controlled temperature (15.6, 22.2, 28.8, 32.2, and 36.1 °C) for an incubation period of eight hours. Development and survival of incubated eggs, larval stages I, II and pupae to adult emergence were highest between 22.2 and 28.8 °C and resistant to temperatures below and above that range. Third larva stage showed a difference, with emergence higher at 15.6 than at 22.2 °C. No adult fly emerged at 36.1 °C. The male and female flies of ages 0, 5, 10, 15 and 20 days were divided into batches (n = 20). Batches of male and female flies was incubated separately for eight hours and further monitored for 72 hours in the laboratory for survival. Adult males and females survived within 15.6 – 28.8 °C than at higher temperatures irrespective of the ages; 36.1 °C had a lethal effect on the flies. There was no significant difference (P>0.05) in the survival of adult flies at incubation and after 72 hours of exposure. The results suggest that the effect of temperature depends upon the stage of development of Chrysomya chloropyga. Temperature is fundamental in the development of C. chloropyga and should be considered during PMI determination and in the formulation of control strategies.

Published: June 2022

Assessment of the duration exposure-dependent effect of carbamate treated net on hepatic and renal functions of albino Wistar rats after 30 and 60 days was carried out. Serum ALT, AST and ALP levels were determined to assess liver function while serum creatinine and urea levels were measured for kidney function. Eighteen (18) male albino Wstar rats weighing 138-146g were divided into 3 groups of 6 rats each. Group 1 served as control, group 2 animals were exposed to carbamate treated net for 30 days and group 3 animals exposed for 60 days. The results showed that the levels of serum AST and ALT increased in all the experimental groups exposed when compared to the control group. ALT increased significantly (p<0.05) in the rats exposed for 60 days (203.83±0.307) while AST increased highest in experimental groups exposed for 30 days (203± 1.613)and 60 days (362± 0.365) respectively when compared to the control (150.5±0.34). ALP increased significantly (p<0.05) only in the group exposed for 30 days (17.67±0.21),but decreased in the group exposed for 60 days when compared to the control group. Serum creatinine increased insignificantly (p>0.05) in the group exposed for 30 days but decreased in the group exposed for 60 days while serum urea level in the group exposed for 30 days remain unchanged but decreased after 60 days when compared to the control group. Statistically, there was a significant increase (p<0.05) in body weight and organ weight of the animals exposed for 30 and 60 days. Therefore, this present study demonstrates that exposure to carbamate treated net may alter the integrity and function of liver thereby causing hepatotoxicity while the exposure of rats to carbamate treated net may not pose any significant nephrotoxicity in rats.

Authors: Lao Thuan Duc , Thuy Le Huyen Ai
Published: June 2022

The deregulation of microRNA-140 (miRNA-140) has been reported to be involved in human pathogenesis of Osteoarthritis (OA). However, in Vietnam, to our knowledge, there are limit study of evaluation of miRNA-140 expression. The commercial kits for the quantitation of miRNA-140 are more expensive. Thus, for the aim to establish the less cost assay for quantitation of miRNAs in developing countries, we designed the set of specific primers to quantify the expression of microRNA for further application on the local population. The sequence of hsa-miR-140-3p was input from miRNA database using the accession number of MI0000456. Following bioinformatics tools, including RNAfold Web Server, BioEdit, IDT Oligo analyzer, were used to design the set of specific primers. As the result, we successfully designed the set of specific primers, including stem-loop primer, named as StL-miR-140-3p, which specific to target sequence of hsa-miR-140-3p, and specific forward primer and reversed primer, named as StL-F-miR-140-3p, and StL-F-miR-140-3p, respectively, which designed for target to the sequence of hsa-miR-140-3p. For further study, it is required to conduct the assay, which based on those designed primers, on the clinical samples to evaluate the specificity, sensitivity, limit of detection, as well as carried on the local population.

Authors: Rahma Nadia , Rokhim Rofikoh
Published: June 2022

Public awareness in social and environmental sustainability became a challenge that turned into general assessments. ESG (Environmental, Social, Governance) performance became essential. Hence, the firm that does not apply ESG criteria in its business activities will face a consequence from investors impacting its performance, associated with financial risk. This study examines ESG performance within ESG score, ESG controversy, and BGD (Board Gender Diversity) on the total and systematic risk as a proxy for the financial risk of public companies listed on the stock exchange. This study uses a sample of 105 listed public firms from each stock exchange in ASEAN-5 (Philippines, Indonesia, Malaysia, Singapore, and Thailand) from 2016 to 2020 and applies panel regression analysis. The result suggests that ESG Score significantly influences total but not systematic risk in ASEAN-5. ESG controversy does not considerably affect total and systematic risk. BGD significantly influences total risk but not systematic risk. The findings will help investors and portfolio managers evaluate how ESG performance influences the firm's financial risk and make better investment decisions in ASEAN-5.

Published: June 2022

Landscape assessment has been limited to methodologies with subjective and qualitative approaches, due to prevailing the concept of landscape as the perception of territory. In this work, the intrinsic visual quality of the landscape was evaluated using an algorithm based on grey clustering and Shannon entropy. The grey clustering method was used to determine the landscape visual quality, and Shannon entropy was applied to calculate wights of criteria used for evaluation. The case study was performed on mining project located in Cajamarca, Peru, where three landscape units were identified and four evaluation criteria were established, before and after the implementation of project. The results revealed that there is a notable effect of the change in landscape visual quality in three evaluated landscapes units. The criteria in order of evaluation were the intrinsic visual quality of the water, relief, vegetation cover, and artificial elements. Consequently, the method showed quantitative and qualitative results that could help the landscape assessment process to make better decisions regarding mining projects. Keywords—Grey clustering, Landscape visual quality, Mining project, Shannon entropy.
Estimating the Water Quality Class of a Major Irrigation Canal in Odisha, India: A Supervised Machine Learning Approach
Authors: Bhoi S. K. , Mallick C. , Mohanty C. R.
Published: June 2022

Contamination of surface water by rapid industrialization, natural and anthropogenic activities is of great concern over the last few decades. Nowadays, canal water systems are no exception to this form of contamination, which results in water quality degradation. To classify the canal water based on the Bureau of Indian Standards (BIS), it was thought to develop a quick and inexpensive approach as an alternative to the time-consuming analysis approach. With this motivation, the present study explores building a machine learning model for water quality classification of a major canal namely the Talaldanda canal operating in the state of Odisha, India. The water quality class is predicted using supervised machine learning (ML) prediction models for the new canal water input parameters. The water quality parameters such as pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), and total coliform (TC) at six strategic locations of the canal from the year 2013-2020 were collected from Odisha State Pollution Control Board for the training phase. The supervised ML models used in the study are Decision Tree (DT), Neural Network (NN), k-NN (k-Nearest Neighbor), Naïve Bayes (NV), Support Vector Machine (SVM), and Random Forest (RF). The predictions of the models are evaluated using the Orange-3.29.3 data analytics tool. When analyzing the performance parameters by sampling the training data into training and testing using cross-validation, the results show that DT has a higher classification accuracy (CA) of 96.6 percent than other ML models. In addition, the likelihood of DT correctly predicting water quality class for the testing dataset is higher than that of other prediction models.

Published: June 2022

The current rapid urbanization, industrialization, and expansion of urban construction patterns have resulted in a large number of residual plaques in the urban area, including both the original plaques that are extremely fragmented and the new plaques that are metabolized by urban production, especially natural habitat patches are more pronounced. Ecological restoration of residual plaques plays an important role in maintaining biodiversity, protecting native species, providing ecological services, revitalizing land resources, inheriting regional characteristics, shaping urban image, and improving the ecological environment. Therefore, research on the subject is necessary and urgent. The topic is based on the ecological survey of urban residual patches and the study of the characteristic attributes of current urbanization, defining the connotation, extension, type, characteristics, and influencing factors of urban residual patches, and analyzing the process of fragmentation of residual plaques in cities and their artificial interference relationship. From the macro, meso, and micro scales, from the top level of ecological planning, the whole process of life cycle management, and the moderately disturbed bottom layer of ecological engineering nodes, three levels are restored, theoretical integration guidance and technical restoration. Based on the three dimensions of the continuous symbiosis of nature, cost control of the economy, and public participation of the society, repair and activate the remaining plaques of the city to provide technical support for the construction and sustainable development of urban ecological civilization.

Authors: Kumar Nishant , Saharan Sunil
Published: June 2022

Due to various reasons, crack formation may occur in the concrete structure. Crack formation increases the permeability of concrete to detrimental substances including different types of chemicals, glasses, and water, which upon contact with concrete leads to significant impairment in various properties of concrete including strength, durability, etc. In the present investigation, special microbiological growth having the ability to precipitate calcite through the process of biomineralization is induced in the concrete to evaluate the performance of the concrete. The bacteria were directly added to the concrete mix instead of encapsulating them into clay pellets. Bacteria were classified into two groups i.e. A & B. i. e. 50 & 100 g of bacteria powder were added into 1 L of water respectively. Out of the two groups A and B, 4 samples each were taken of 10 mL, 20 mL, 30 mL and 40 mL, and mixed in the concrete. The results showed that compressive strength and flexural strength increased up to 23.57% and 35% respectively more than the control specimen and the optimum capacity achieved at 30 mL bacterial concentration.

Published: June 2022

The socio-economic and institutional systems of a developing country like India have a big role in the effects of perception on the choice of adapting capability. The study uses exploratory factor analysis to better understand these implications in a regional context (EFA). Therefore, survey research is carried out in Sindhudurg district of coastal Maharashtra, with 410 respondents, assessing perception. EFA leads to the unpacking of latent constructs evaluating the perception of climate change, which in turn affects adaptive capacity and livelihood resilience. These constructs are biophysical impact cognition, motivation to change, economic diversification, and adaptive skills, which together account for 50% of coastal fishermen’s perception of climate change. Multivariate analysis of variance (MANOVA) revealed differences in the interpretation of these factors among coastal fishermen from various backgrounds (MANOVA). Overall, the research emphasizes the importance of perception in determining adaptive choices and resilience. According to the findings, developing adaptation-friendly infrastructural areas is recommended for society’s resilient functioning.

Authors: Xu Tianyu , Zhi Shuteng , Zhao Songyi , Yang Qiliang
Published: June 2022

This study investigated the responses of Panax notoginseng in a high-altitude area to regulated deficit irrigation at different growth stages (seedling stage, vegetative growth stage, flowering stage, and root weight gain stage) by observing indicators such as plant growth, soil nutrients, and morbidity. Conventional irrigation (70%-80% FC) was applied at the seedling stage and the root weight gain stage. Three regulated deficit irrigation levels (50%-60% FC, 40%-50% FC, and 30%-40% FC) were applied during the vegetative growth period, and three regulated deficit irrigation levels (70%-80% FC, 50%-60% FC, and 40%-50% FC) were used in the flowering period. Conventional irrigation was also applied throughout the growth stage as a control (CK). The results showed that the content of available phosphorus, available potassium, and nitrate-nitrogen in the soil was the lowest under the T4 treatment, and the cutting+main root length, rib length, root surface area, root volume, and main root diameter all reached their maximum values under this treatment. Under the T4 treatment, the total saponin content and total dry weight were the highest, the irrigation water use efficiency was the highest, and the P. notoginseng morbidity rate was the lowest. Morbidity was reduced by 53.42 percent in individuals who received the CK therapy, whereas total saponin content increased by 8.65 percent. The T4 therapy had the highest score of all the treatments in principal component analysis. As a result, planting P. notoginseng under the T4 treatment can effectively reduce irrigation water usage, enhance production and quality, and minimize the incidence of sickness in P. notoginseng.

Authors: Sajath S. H. M. , Nihmiya A. R. , Arachchige U. S. P. R.
Published: June 2022

The sludge produced in the treatment process depends on the type of coagulant and other chemicals used and the suspended particles present in raw water. Discarding this sludge in the landfills poses pollution of both ground and surface water, disturbing the lives in the water and the water quality. The primary potable water provider in Sri Lanka is the National Water Supply and Drainage Board. It focuses on finding ways of disposal, sustainable practices, and possible applications of the water treatment sludge. This research aims to identify the aluminum level in the potable water treatment sludge of the Konduwattuvana water treatment plant in Ampara and to utilize that sludge as an alternative raw material in burnt clay brick manufacturing. The national standards and limitations of the sludge content and the standard brick manufacturing process were followed. To reach the aim, a sequence of tests was conducted, and the brick characteristics are subjected to test for different sludge ratios according to the Sri Lankan Standard of 36:1978 for burnt clay bricks. Experimental results show that the aluminum content in liquid sludge and sludge cake was found to be 231.6 mg.L-1 and 54.9 mg.L-1, respectively, which implies that the sludge contains aluminum. The optimum sludge ratio to produce burnt clay bricks was found to be 10% of the total weight of the brick.
Toxicity and Challenges of Nanomaterials and Their Impact on the Environment
Authors: Awasthi Sakshi , Sharma Jai Gopal
Published: June 2022

Nanomaterials (NMs) are those tiny materials that range from 1-100 nm. These materials show different characteristics in their physical and chemical forms in comparison to their bulk form. The use of nanomaterials is increasing day by day because of their enormous capabilities in the health sector as well as in other industries. There are currently few, if any, actual protocols for the disposal and characterization of these nanomaterials, which results in environmental toxicity. Heavy use of chemicals in the testing of nanomaterials has resulted in polluting our entire ecosystem. Inconsistent results of nanomaterial show that it is challenging to reduce the toxicity generated by it. In this review, we discuss the administration and use of nanomaterials in the agribusiness sector, in food, and, most importantly, in the environment, for purposes of protecting our plants and crops, dealing with incurable diseases, developing new tastes and textures in the food sector, sensations, identifying pathogenic organisms, and distribution systems where these minute particles can wreak havoc. Despite the potential benefits of nanomaterials, their unintentional harm to the environment and, in some cases, our health is making further development difficult. This article discusses the toxicity of nanomaterials and how they damage our environment, as well as the obstacles that come with overcoming them.

Authors: Kunwar Singh Akshi , Kumar S. S.
Published: June 2022

The impact of fruit and vegetable waste is becoming a significant concern for the environment. The biomaterial waste generated from fruit processing industries is very high. When discharged as processed waste, it also increases water pollution. 45% of the total industrial organic pollution originates from food processing industries. These generated wastes are suitable for the production of biochemicals. Pectin is one such biochemical that plays a vital role in reducing the burden on the environment. Pectin helps in the manufacturing of confectionaries. Vegetable waste like beetroot, carrot, beans can also act as a source for pectin production. This study depicts extracting Pectin from mixed fruit pomace waste. Mixed fruit (Orange, Pomegranate, Banana & grapes) pomace waste reacts with 0.1N HCl. This reaction uses a 2-stage crosscurrent solid-liquid extraction technique. For its nature, obtained pectin was tested as calcium pectate using methylated spirit. The filtrate from 2-stage crosscurrent leaching was further dried in an oven. RSM technique helps in optimizing parameters like drying time, temperature, pH, and concentration. The experimental setup generated Pectin gave an efficiency of 11.52% for 22.4g of dried mixed fruit pomace waste.

Published: June 2022

This text is an attempt to lucidly present the intellectual biography and theoretical work of Immanuel Wallerstein, the main architect and exponent of world-systems analysis. Given that the entire Wallerstein’s work has been devoted to understanding the reality of the modern world-system as the fundament of every prudent action, this paper should simultaneously be read as a homage to one of the greatest names of the 20th century sociology, and as a reflexion on chaotic present and uncertain future of the world we live in. Having in mind his wide range of scholarly interests and a gargantuan oeuvre left as a legacy, we have selected four main topics discussed in Wallerstein’s work. After a concise review of Wallerstein’s intellectual biography in the introduction, the first part focuses on the methodological and epistemological postulates of world-systems theory. The second part discusses the issue known as the “long sixteenth century”, that is, the genesis of the capitalist worldeconomy, which is also the topic of the first volume of Wallerstein’s most important work The Modern World-System. The third part reviews the historical trajectory of antisystemic movements, from the Old Left in the 19th and the first part of the 20th century, to world revolution of 1968 as a turning point in their development, to modern varieties of these movements. The fourth part discusses the issue of rise and fall of the United States of America as a hegemonic power of the world-system.

Published: June 2022

In this paper, following the concept of AI-statistical convergence for real sequences introduced by Savas et al. [22], we deal with Korovkin type approximation theory for a sequence of positive convolution operators defined on C[a, b], the space of all real valued continuous functions on [a, b], in the line of Duman [6]. In the Section 3, we study the rate of AI-statistical convergence.

Published: June 2022

In this paper we describe some basic notions of topological dynamical systems for maps of type f : X × X → X named general systems. This is proved that every uniformly expansive general system has the shadowing property and every uniformly contractive general system has the (asymptotic) average shadowing and shadowing properties. In the rest, Devaney chaos for general systems is considered. Also, we show that topological transitivity and density of periodic points of a general systems imply topological ergodicity. We also obtain some results on the topological mixing and sensitivity for general systems.

Published: June 2022

In the present paper, a general subclass Mh,p Σm (λ, γ) of the m-Fold symmetric bi-univalent functions is deĄned. Also, the estimates of the TaylorMaclaurin coefficients |am+1|, |a2m+1| and Fekete-Szegö problems are obtained for functions in this new subclass. The results presented in this paper would generalize and improve some recent works of several earlier authors.

Abstract: Humanistic Education Theory is humanizing humans. In its development, the model of Christian religious education must be humanistic that can be applied to all groups or individuals in accordance with heterogeneous social conditions, which are not only focused on formal religious education. How is the diversity and pattern of religious education carried out in accordance with the socio-psychology of students so that it is effective and on target. The method used in this writing is a qualitative method with literary studies. The application of humanistic theory refers more to the spirit or spirit during the learning process which colors the method applied. The teacher's role in humanistic learning is to become a facilitator for students. In this case, the teacher's role is very dominant in influencing all sides of students' lives because the teacher is considered a role model, role model and barometer in deciding and instilling all forms of positive attitudes to shape the character of their students. In this case we are taught to support each other to make our neighbors perfect like Christ. One of the principles of humanistic learning theory is that humans have the ability to learn naturally. That is, a person naturally has curiosity and a deep desire to explore the world.
