Diffusion-driven instability and pattern formation in a prey-predator model with fear and Allee effect
Authors: Pal Debjit , Kesh Dipak , Mukherjee Debasis
Published: April 2023

This paper analyses a predator-prey model with Holling type II response function incorporating Allee and fear effect in the prey. The model includes intra species competition among predators. We find out the local dynamics as well as Hopf bifurcation by considering level of fear as bifurcation parameter. The condition for diffusion-driven instability and patterns are then demonstrated in relation to the system's ecological parameters and diffusion coefficients. Intra-specific competition affects the dynamics of the system and Turing pattern formation. Moreover, output of results is verified through numerical simulation. Thus, from a dynamical standpoint, the considered model seems to be relevant in the field of ecology.

Published: April 2023

Este artigo traz reflexões sobre o sistema fascial na aproximação com os estudos somáticos e a Educação Física. Deste escopo, apresenta-se um caminho de sensibilização, que pretende dar visibilidade para a perspectiva facial na orientação do trabalho corporal. Tal caminho chama a atenção para o fato de que somos seres de natureza viscoelástica, e, enquanto tais, embora sejamos amplamente sujeitos à lógica biomecânica newtoniana, pulsamos nas entrelinhas dessa leitura calculista de compreensão da vida, de modo a afirmar a linguagem das (in)tensões, de onde se evidencia o sistema fascial. Neste sentido, as fáscias oferecem possibilidades interessantes para ingressarmos à fundo na linguagem e na compreensão do movimento humano.

Published: April 2023

La criptococosis es una micosis grave que se manifiesta, en el 90% de los casos, como una meningoencefalitis especialmente en los enfermos VIH positivos. 

El objetivo de este estudio es describir los casos de criptococosis extrameníngea en personas viviendo con VIH y conocer cuántos de estos padecen compromiso meníngeo concomitante. Además, determinar la relación con el título de antígeno polisacárido capsular de Cryptococcus en suero. 

Se realizó un estudio retrospectivo, observacional y analítico.  Se incluyeron a los pacientes VIH positivos cuyo diagnóstico inicial se había realizado a partir de muestras extrameníngeas en el período comprendido entre 2012 y 2019. Los enfermos se dividieron en 2 grupos. Grupo 1 pacientes sin compromiso meníngeo; grupo 2 aquellos que finalmente tenían compromiso del SNC. 

De un total de 531 criptococosis registradas en ese período, se incluyeron 113 enfermos (21%), de los cuales en 58 se comprobó el compromiso meníngeo. No se observaron diferencias significativas en cuanto a la mortalidad entre ambos grupos.

Ninguno de los enfermos con antigenemia por LFA (antígeno capsular en suero por inmunocromatografía) positiva, pero con antigenemia por aglutinación de partículas de látex (AL) negativa tuvo compromiso meníngeo.

Se observó que títulos de antígeno para Cryptococcus en suero por AL mayor o igual a 1/100 se correlacionaron con un aumento de 30 veces en la posibilidad de padecer meningitis.

En todos los casos se debe descartar el compromiso del SNC. La AL sigue siendo una prueba útil y complementaria, debido a que en los casos con AL negativa no se observó compromiso meníngeo.

The Turkish Nation as a Bridge: Imagining a Nation in Turkish Parliamentary Discourse
Authors: AYKAÇ Erdogan
Published: April 2023

This article analyses Turkish parliamentary discourse about Turkish communities living outside of Turkey from 1988 to 2016. It focuses particularly on the usage of the bridge metaphor in discursive strategies towards these communities; concentrated mainly in former Ottoman territories and parts of Eurasia. The article argues that Turkish parliamentarians used the bridge metaphor to frame Turkish communities as part of both the Turkish nation and the nation where they lived, thereby constituting their liminal and in-between identity. Parliamentarians continuously (re-)imagine, (re-)construct, and (re-)produce the Turkish nation by using different discursive strategies that included uniqueness, sameness or difference. They used identity markers as ethnicity, language, geography, history, and religion to address these strategies. Metaphorically framing Turkish communities as a bridge provided them a dominant bridge role, namely that of friendship and peace. By transforming Turkish communities into a bridge of friendship and peace, through different dimensions, they believed that they would have a positive and crucial role for the country where they live and for Turkey. This bridge role provided opportunities as well as limits, illustrating the interplay between discourse and foreign policy developments.

Authors: O.S. Epor , H. Yua , C. Nwakoby
Published: April 2023

One of the greatest challenges of the Sub-Saharan African economies today is how to develop the appropriate model that will propel development in the continent. The manufacturing sector instances in China, Malaysia, Taiwan, Korea and Japan are clear models to adopt for Nigeria. The question now is, what has Nigeria been doing to develop the manufacturing sector? To this end, this study set out to examine the effect of fiscal policy and private investment on the performance of the manufacturing sector in Nigeria from 1981 to 2021. The study is time series in nature and made use of the autoregressive distributed lag (ARDL) modelling technique. It was found that domestic private investment and aggregate government spending exert a significant positive influence on the manufacturing sector performance in the long run, while the influence from tax and government revenue was significantly negative. It was then recommended that government should improve on the factors that attract more FDI inflows into the country; boosts requisite educational training skills and financial market depth to drive the influence of domestic private investment on the manufacturing sector; increase government spending on the manufacturing sector development; and that tax revenues be judiciously utilized in the long-run so that they can positively impact the manufacturing sector.

Authors: Shinta Maharini Fransisca , Amridjati Maria , Poddar Sandeep
Published: April 2023

One of the Indonesian traditional food, growol is a fermented cassava product of the home industries. It is believed that growol can cure diseases in the digestive tract. This research aims to analyze the standardization of growol processing and the effects of various processing processes, i.e. steaming, baking, frying, and cooling, on growol potential as traditional food. Four variations of fermentation treatments were used to investigate the standardization of growol processing, namely the fermentation process. Based on the organoleptic test encompassing appearance, texture, taste, and overall preference and the LAB level test, the best growol was that with the fermentation process “not changing the water in three days” (TG3). As such, we figured out the standardization of growol processing comprising preparing the basic ingredients, performing the fermentation “not changing the soaking water in three days”, washing five times (b/v) draining, crushing, steaming, and molding. The glycemic index of baked, steamed, cooled, without-processing, and fried growol was 97, 94, 93, 91, and 89, respectively. With a GI > 70, without processing, steamed, baked, fried, and cooled growol could not be consumed as functional pro-diabetic food. The LAB test indicated that the LAB level of without- processing, baked, fried, steamed, and cooled growl was 1.32 × 107 cfu/g, 6.7 × 103 cfu/g, 1.53 × 103 cfu/g, 1.27 × 103 cfu/g, and 2.7 ×102 cfu/g, respectively. We could then infer that without processing growol and steamed, baked, fried, or cooled growol had potential as a functional prebiotic food.

Teneligliptin (TNN), a true third-generation gliptin, has firmly established itself as an essential therapeutic molecule in the therapy of diabetes. The monitoring of isopropyl alcohol (ISO), t-butanol (BUT), 2-bromo propane (BRO), toluene (TOU) and acetic acid (ACE) in TNN is necessary to maintain TNN’s stability, bioavailability and solubility. We have established a “gas chromatography” approach for ISO, BUT, BRO, TOU and ACE determination in TNN sample. The analysis of ISO, BUT, BRO, TOU and ACE in TNN were performed deploying ZB-624 analysing column. The flame ionizing sensor was deployed. Linear response was ascertained for ISO, BUT, BRO, TOU and ACE over the concentration arrays 29.96 to 7512ppm, 25.83 to 759 ppm, 48.48 to 762ppm, 4.92 to 1362ppm and 222.41 to 7527ppm, respectively. Detection limits were 8.99ppm (ISO), 7.75ppm (BUT), 14.55ppm (BRO), 1.34ppm (TOU) and 67.47ppm (ACE). The “gas chromatography” approach validation set their precision, specificity, accuracy and robustness.

Published: April 2023

The increase in malaria morbidity and mortality due to artemisinin derivative resistance was a global problem. Marine biota, curry fish or Sticophus hermanni was known to have bioactive components that are antibacterial and antifungal. The purpose of the study was to observe phytochemical tests and antimalarial activity of golden sea cucumber, curry fish using two types of solvents with different polarities using In vtro studies. The study was a true experimental study withIn vtro protocols, which included: (P1), control negative; (P2) P. falciparum medium with n-hexane extract of curry fish; (P3) P.falciparum medium with ethyl acetate extract of curry fish. The parameters were as follows: phytochemical assay, growth %, inhibitory rate, and IC50. The phytochemical analysis found various bioactive components in the ethyl acetate extract, including flavonoids, alkaloids, steroids, and tannins, whereas the n-hexane extract includes fewer active components, including flavonoids, alkaloids, steroids, and tannins. The extract's antimalarial action is demonstrated by a decrease in parasite growth, a rise in the inhibitory rate with increasing extract dose, and IC50 less than 5 µg/ml when administered with ethyl acetate and n-hexane. Both solvents in curry fish extract displayed high antimalarial activity; however, n-hexane had a lower IC50 than ethyl acetate.

Published: April 2023

Chemobrain is a typical adverse effect of chemotherapeutics agents that affects 15–80 percent of cancer patients. Doxorubicin, an antineoplastic drug, has been associated with severe neurotoxicity manifested as a loss in cognitive skills, most likely due to oxidative stress in brain. Krill oil (KO) is a unique, naturally occurring nutrient derived from a type of Antarctic krill, Euphausia superba that is commonly used as a dietary supplement and is well known for anti-inflammatory, hypolipidemic, anti-depressant and improvement of cognitive function, protection of neurodegeneration, neuroprotective and antioxidant qualities. The current study was aimed at evaluating krill oil's potential neuroprotection and memory improving benefits against Doxorubicin-induced cognitive and neurobiological defects. A novel object recognition task and Morris water maze test were conducted to evaluate the protective effect of krill oil against doxorubicin-induced memory deficits in rats. In female Wistar rats, cognitive impairment was produced by administering ten cycles of Doxorubicin (2.5mg/kg, intra peritoneal, once every five days). Krill oil (50mg/kg and 100mg/kg) was given orally starting one week prior to the doxorubicin treatment and continued throughout the study. Krill treatment (50mg/kg and 100mg/kg) significantly protected against Doxorubicin induced memory impairment. Co-administration of both doses of krill oil resulted in significantly lower the levels of tumour necrosis factor (TNFα), and acetyl cholinesterase activity. Furthermore, doxorubicin-induced oxidative and inflammatory insults in the frontal cortex and hippocampal areas of the brain were prevented by krill oil. In conclusion, krill oil may be a promising adjuvant treatment option for reducing adverse effects associated to doxorubicin treatment.

Authors: Arvapalli Swarupa , Anka Rao A.
Published: April 2023

This research work focuses on development of proniosomal efavirenz (EFV) formulation using maltodextrin as a carrier. Thus an effort is made to increase the effectiveness of oral drug delivery of EFV by blending them in proniosomal powders (maltodextrin-based). The slurry method was employed for the preparation of proniosomes. A mix of Span-60, cholesterol and maltodextrin were used for its preparation..Box Behnken Design used to study the effect of independent variables X1, X2, and X3 (maltodextrin, Span-60 and cholesterol) on response variables Y1, Y2 and Y3 (Entrapment efficiency ,Vesicle size and Cumulative Drug Release percentage). Scanning Optical electron microscopy was used for studying surface-morphology of proniosome (optimized) and proniosome formation. To study any drug interaction or its conversion to the molecular and amorphous state from crystalline state, various tests like differential scanning calorimetry and FT-IR were performed. Compared to EFV in pure form, the proniosomalmaltodextrinbaseddrug showed better dissolution 98.41% in vitro-dissolution study. The optimized Efavirenz loaded proniosomal formulation showed maximum permeation (2614±215µg) in rat intestine as compared to pure drug(1500±114µg). The effectiveness of this drug (oral delivery) is obvious from the fact that rat intestine drug permeation is better. This shows maltodextrin-based EVF proniosomal formulation is suitable for oral delivery of efavirenz.

Published: April 2023

Human health and environmental hazards associated with pesticide handling are common in developing countries, as farmers and agricultural workers frequently lack proper personal protective equipment and may be unable to understand labels with safety instructions. Importation, distribution, use, storage, and disposal of pesticides. Pesticide utilization globally is increasing every year and Myanmar pesticide utilization is also increasing year by year. Its global rank of utilization is 86 and the quantity of pesticide application dosage is 1.4 kg per hectare. Although Myanmar's pesticide application rate per hectare is not as high as in other countries, ignorance of the pre-harvest interval after pesticide application, failure to follow labeling guidelines, calibration, misuse, and improper disposal pose a serious threat to human health and the environment. The goal of this review paper is to examine the uses and application of pesticides in Myanmar to raise awareness about pesticide misuse and to understand the negative effects of pesticides on human health and the environment. Pesticide misuse is a severe problem in agricultural productivity, putting farmers' health and environment at hazard. Pesticide impacts on the environment have a long-term effect on human life, according to numerous studies, it persists in the environment with long-term negative effects. As a result, pesticide management should be strictly regulated for the whole supply chain process of pesticides.

Summary of Newly Found Ants’ Cognitive Abilities, and Their Occurrence in Humans
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: April 2023

Authors studied the cognitive abilities of the ant Myrmica sabuleti Meinert 1861, and in addition to the separate publications of their findings, they also summarized them in until now three papers. Here, the authors summarize their eight last findings, and report similar abilities in humans as well as advices for acquiring and using them. The ants can associate visual cues, numbers of elements, and odors with the time periods of their occurrence, and do so taking into account the characteristics of the elements. Humans should do so for ameliorating their daily life. For adding two numbers, the ants must see them with a time gap not exceeding 8 minutes. The ants discriminate recent and previously perceived events, locating the recent but not the old ones on a ‘time line’. Humans must learn to evaluate the passing time, to have a ‘time line’. The ants’ time perception is underestimated when they are more active. This is true for humans, and must be considered while working, playing or doing nothing (e.g., elderly persons). The ants can navigate using a learned (memorized) sequence of odors. Humans must learn sequences of cues for finding their way. The ants discriminate even and odd numbers until the number 7. Humans are sensitive to numbers’ parity, and this should freely impact their choice. Shortly, the authors revealed four cognitive abilities in ants which should occur in humans, natively or acquired through experiences, at a more precise, complex and extended level, in order to provide them with an as comfortable as possible live.

A Comparative Analysis of the Computation Cost and Energy Consumption of Relevant Curves of ECC Presented in Literature
Authors: Elhajj Mohammed , Mulder Pim
Published: April 2023

With the Internet of Things (IoT) becoming expo-nentially more prevalent, the need for lightweight cryptography functions increases simultaneously. Namely, IoT end devices are mostly limited by their resource-constrained capabilities and therefore cannot rely on heavyweight cryptographic algorithms such as Rivest-Shamir-Adleman (RSA) or Diffie-Hellman (DH) for security. Elliptic Curve Cryptography (ECC) offers a more lightweight alternative by being based on a mathematical prob-lem named the Elliptic Curve Discrete Logarithm Problem (ECDLP) which is not known to be solvable in sub-exponential time. Within the field of ECC, many different curve types exist following various standards for this protocol. In this paper, the energy consumption and time consumption for key generation, encryption, and decryption are measured within the ElGamal protocol using ECC for the various curves. To measure this, a Raspberry Pi 4B and a Personal Computer are used to conclude the disproval of the hypothesis that the Twisted Edwards curve performs most efficient to achieve its security strength. Namely, Brainpool curves function most efficient within this benchmark, after which Short Weierstrass curves follow. Moreover, it is concluded the performance pattern for both data processors and data providers is equal to each other for all message sizes.
Asymmetric Dynamics of Rent and Vacancy Rates in the Tokyo Office Market
Authors: Matsuo Kazushi , Tsutsumi Morito , Imazeki Toyokazu
Published: April 2023

In recent years, it has been shown that the dynamics of office markets are asymmetric depending on the market conditions and the direction of supply and demand shocks. However, the actual state of asymmetry varies significantly from market to market, and an overview of the discussion is needed. In this study, we test our hypothesis on asymmetric dynamics in the Tokyo office market, one of the world's largest markets. We employ the rent-adjustment process model proposed by Englund et al. (2008), an improved and more realistic version of the error correction model that captures the interaction between rent, vacancy rates, and stock. The data of the Tokyo office market range from January 2000 to September 2015 and cover ten regions. The results reveal that the mechanism of rent and vacancy rate fluctuation depends largely on the direction of change in supply and demand and on market conditions, especially the upward and downward movements of rents. It is also shown that increases in demand and supply not only encourage rents toward equilibrium, but also have the effect of overshooting them. These results can be valuable in properly capturing future shocks in demand and supply.

Drawn from a very recent past, green finance is an attempt to answer the thorny issue of climate change and the loss of biodiversity.

Our readers will remember that the idea of setting up funds capable of compensating solution countries, protectors of their forests without which life on earth would become catastrophic,is a long-heard panacea,unfortunately,those who are supposed to crystallize it are sulky and do not have before them  no coercive measures. Several issues and challenges must be taken up in order to finally hope to reach an agreement between the polluters and the coutries with solutions. The Cop 27 projected as a final meeting likely to remove any ambiguity seems rather a stillborn. As long as it does not have binding legal texts thus putting the polluters before their responsability, the impossible will be the green finance.

Authors: Xi Chen , Xianyin Li
Published: April 2023

This study explored a mediation model among teachers of basic education on the Chinese mainland. Knowledge sharing was identified as a mediator between collective teacher efficacy and teaching innovation. 732 valid samples from the Chinese mainland were obtained. Three structured instruments were applied including a scale of collective teacher efficacy, a scale of knowledge sharing and a scale of teaching innovation. The responses were recorded using a 5-point Likert scale. Structural equation models were used to construct measurement and structural models. Collective teacher efficacy has a significant and positive predictive effect on teaching innovation and knowledge sharing. Knowledge sharing has a significant and positive predictive effect on teaching innovation and it plays a partial mediating role on the impact of teachers' collective effectiveness on teaching innovation. The mediating effect accounts for 29.03%. The results show that knowledge sharing can promote the positive impact of collective teacher efficacy on teaching innovation in basic education. This study provides new ideas for schools to improve teaching innovation that will create a new school-based learning environment for teachers to improve their professional learning and teaching practice.

Estudos sobre a acidez das chuvas têm sido aprofundados principalmente em regiões urbanizadas e industrializadas, onde se observa um efeito mais visível do resultado da interferência humana sobre o ambiente. O aumento da acidez da chuva é causado pela presença de poluentes liberados na atmosfera, como óxidos de nitrogênio, dióxidos de carbono e de enxofre, provenientes principalmente da queima de combustíveis fósseis. Este estudo buscou analisar a qualidade da água da chuva em cinco estações pluviométricas da Bacia Carbonífera Catarinense (BCC), sul de Santa Catarina. A amostragem foi realizada na água de chuva coletada em pluviômetros convencionais, com frequência bimestral, durante 10 meses. Os indicadores analíticos analisados foram: pH, Condutividade Elétrica, Turbidez e Acidez Total. Foi determinado ainda em laboratório, sulfatos, cloretos e dureza. Observou-se acidez e condutividade mais elevadas nas estações pluviométricas de Siderópolis, Criciúma e Içara, sugerindo que estes locais estão mais sujeitos as emissões de contaminantes atmosféricos. O pH médio ponderado pelo volume (MPV) da região foi de 5,41, variando de 4,65 a 7,59. A condutividade média foi de 63,83 µS.cm-1 e a turbidez de 6,18 NTU, indicando que nos períodos analisados houve pouca presença de partículas em suspensão e matéria orgânica.

Published: April 2023

In recent years, social enterprises have developed by leaps and bounds, involving more fields with a profound social impact in the sector of national non-governmental public welfare. However, the development of social enterprises in China is still in the initial stage, encountering the challenges such as legal legitimacy, moral legitimacy, and cognitive legitimacy. The purpose of this paper is to review the concept of social enterprises, analyze the implementation of the “New Citizen Plan” which is an activity of the Nandu Public Welfare, and the problems faced by the development of domestic social enterprises from the perspective of blended value and the triangular relationship of social enterprises. Finally, referring to the development models of social enterprises in other countries, this paper puts forward some suggestions for future development from the aspects of government and social enterprises. On the one hand, the government should optimize the environment, integrate resources, and provide normative legal support in a macro manner to promote the sustainable development of social enterprises in China. On the other hand, social enterprises should accurately identify the environment from a micro perspective and carry out precise positioning. Through in-depth cooperation and innovation, a win-win result for public welfare and commerce will be achieved, offering more ideas for the growth of social enterprises.

The advantages of collaborative writing on students' writing correctness have received much attention from researchers, but the benefits of this method on students' writing fluency have not been shown. Not only that, but no research up until now has looked at how students might work together to write argumentative essays. This essay aims to address such knowledge gaps. A total of 62 college sophomores with an English major participated in the research. One area where the two groups were treated differently was during the writing phase. While the 25 students in the control group worked together on an outline and developed ideas for an essay, the thirty-five students in the experimental group wrote their papers as a group. The pre-tests, post-tests of both individually and jointly produced papers, and the semi-structured interviews administered to the students provided the data for this study. The research finds that students' writing fluency improved significantly in group and individual writing tasks after engaging in collaborative writing. In addition, the research developed a helpful framework for collaborative writing tasks that may be used in writing schools.
Effect of Temperature and Rainfall Variability on Selected Crop Yields in Wenchi Municipality of Ghana
Authors: Kwakye Jacob
Published: April 2023

The paper examines how rainfall and temperature variability affect the yields of selected food crops in the Wenchi municipality of Ghana. The study employed the quantitative research method to achieve its objective. The datasets consisted of historical records of monthly observational data of temperature and rainfall collected over 22 years (2000-2021), and yearly records of cassava, yam, and maize yield data collected over 22 years (2000 to 2021). Trend analysis was conducted to examine the trend in the climate variables (temperature and rainfall) and the yield of the selected food crops (cassava, yam, and maize) over the study period. A marginal variation in annual rainfall and temperature was observed over the study period. The municipality experienced slightly decreasing trends in annual rainfall and increasing trends in annual temperatures. Significant variations and increasing trends in the yields of the respective food crops were observed. Using standard regression methods, the result shows that maximum and minimum temperatures are associated with increased yields for yam, maize and cassava, but annual rainfall is not significantly associated with the variations in the yields of the selected food crops. The study, therefore, suggests that further research be undertaken to investigate how other environmental and non-climatic factors influence crop production in the Wenchi municipality.
