Authors: MURALIKRISHNA PONNAGANTI , BABU ANCHA KISHORE , MAMATHA PALANATI
Published: July 2022

Objective: Ceritinib is an anaplastic lymphoma kinase (ALK) inhibitor used to treat lung cancer. In the current research, the ceritinib-loaded nanobubbles were prepared by using perfluorobutane for inner core and medium molecular weight chitosan for the shell.
Methods: A 33Box-Behnken design was used to determine the influence of L-α-Phosphatidylcholine (A), the concentration of chitosan (B) and concentration of palmitic acid (C) factors affecting particle size, and polydispersity index. The individual effects of these factors on particle size and polydispersity index were depicted in perturbation plot, response surfaces and counterplots based on Derringer’s desirability approach.
Results: The extreme desirability function value was obtained at A: 1.31 % w/v, B: 3.00 % w/v, C: 1.5 % W/V. Three batches of formulation were prepared in accordance to the desirability function and evaluated. TEM images revealed the superficial morphology and core-shell structure of nanobubbles in the size range of 150-200 nm. Nanobubbles were able to load ceritinib with an encapsulation efficiency of 79.12 % and a loading capacity of 19.2 %. The nanobubbles released about 95.67 % drug in 24h. The in vitro cellular uptake study results show the enhanced cellular uptake of ceritinib with ultrasound from nanobubbles. In vitro cytotoxicity study results indicated that ultrasound-assisted nanobubbles can effectively release in the cells with high sensitivity.
Conclusion: Chitosan-based ceritinib nanobubbles, therefore, offer a remarkable tool for the development of ultrasound-responsive formulations that deliver drugs to the target.

Objective: A validated stability-indicating RP-HPLC method for Atenolol and Nitrendipine was developed by separating its related impurities.
Methods: By using Waters HPLC e-2695 quaternary pump with a PDA detector of 2998 instrument, the chromatographic separation of Atenolol, Nitrendipine and its related impurities was achieved on the column of Agilent eclipse C18 (150x4.6 mm, 3.5 µ) using gradient elution with a buffer containing 0.1percent formic acid and acetonitrile as a mobile phase with a flow rate of 1 ml/min at ambient temperature. A detector wavelength of 218 nm utilizing the PDA detector was given in the instrumental settings. The linearity was studied between the concentration range of 6.25-37.5 µg/ml of Atenolol, 0.75-4.5 µg/ml each of Atenolol imp-A, imp-B and 5-30 µg/ml of Nitrendipine, 0.5-3 µg/ml each of Nitrendipine imp-1, imp-2 were injected with a run time of 40 min. Validation of the proposed method was carried out according to an International Conference on Harmonization (ICH) guidelines.
Results: LOD and LOQ for the Atenolol and its impurities were established with respect to test concentration. The plotted calibration curves were linear with a regression coefficient of R2>0.999, indicating that the linearity was with in the limit. As a part of method validation the parameters like specificity, linearity, accuracy, ruggedness, robustness were determined and the results were found to be within the allowable limit.
Conclusion: The method developed was found to be applicable to routine analysis and to be used for the measurement of active pharmaceutical ingredients (i. e, Atenolol, Nitrendipine and their related impurities). Since there is no HPLC method reported in the literature for the estimation of Atenolol, Nitrendipine and their related impurities, there is a need to develop quantitative methods under different conditions to achieve improvement in specificity selectivity etc.

Published: July 2022

In Burkina Faso, cultivation operations (tillage, sowing, weeding, fertilization, etc.) are mainly carried out by women and young people. Among them, sowing is a particular constraint that determines the success or failure of production. In this country, maize is grown by 78% of producers in the rainy season. In order to improve production, a simple seeder that can be made by local craftsmen was designed as part of the Appropriate Scale Mechanization Consortium (ASMC) project and evaluated with SR21 maize seed in the Koumbia region. It has been harnessed by two oxen. The equipment is evaluated on a plowed plot and on minimum tillage plot. Seed dimensions and distribution disc characteristics were measured. The characteristics of sowing, the traction force and the labor times were measured and compared with those of manual sowing. The results indicate that the sowing time is 3.6 to 3.8 h ha-1, i.e., 8 to 10 times faster than manual practice. The traction force is 22.6 kgf (226 N). That is available for oxen hitch even with one animal. Seed calibration can improve tool performance. The tool has great potential for increasing production if the other production inputs are assured.

The play experience provided pre-service teachers with the opportunity to entangle with materials and to contemplate the nature of play. Conclusions This study suggests that the play process in which pre-service teachers explore materiality is truly the nature of play and found the value of play in exploring materiality. For the settle down of children-led play, which is noted in the 2019 revised Nuri curriculum, this research suggest that pre-service teachers should have experience not simulation classes but the opportunity to experience the nature of play.

Os textos aqui apresentados foram redigidos por estudantes das turmas de 8º ano durante o ano letivo de 2021, e se inserem nos estudos de narrativas orais tradicionais que dão início aos conteúdos de Literatura e Língua Portuguesa daquele ano. A atividade proposta envolve conceitos como identidade, estilística e escrita criativa, e tem como objetivos exercitar a percepção dos elementos culturais, sociais, geográficos e históricos específicos envolvidos nas narrativas estudadas e estimular a observação sensível e imaginativa de estudantes a respeito de suas rotinas e vivências. O material de base para esta produção foi uma coletânea de mitos de criação de povos de diferentes partes do mundo, construída pela professora de Literatura e Língua Portuguesa da turma, a partir de diferentes fontes na internet. Após o estudo de traços identitários e estilísticos dessas narrativas (considerando que elas são transcrições que adotam certas características para se aproximarem do ritmo de contação de histórias das tradições orais, tais como frases curtas, concretude e quase ausência de adjetivação), solicitou-se que fossem produzidos textos que dessem uma explicação não-científica quanto à origem de algum objeto, tradição ou lugar. O critério de seleção para esta publicação foi a escrita criativa aplicada ao tipo textual.
O espaço físico em sala de aula e as adaptações curriculares para alunos com deficiência do Ensino Fundamental: um repensar necessário
Authors: Nakanichi Claudia , Ribeiro Débora Inácia
Published: July 2022

Este estudo objetivou pontuar a necessidade de se repensar a estrutura dos sistemas educacionais acerca da gestão de sala de aula e a do aprendizado para atender aos alunos com deficiência que hoje frequentam a escola regular do Ensino Fundamental. A fundamentação teórica pautou-se nos autores expoentes da Educação Inclusiva: Glat (2007), Mantoan (2003), Mantoan e Prieto (2006), Prieto (2007), Renders (2006). A investigação adotou a abordagem qualitativa com objetivo descritivo e estudos correlatos com pesquisa em bases de dados: PePSIC (Periódicos Eletrônicos em Psicologia), SciELO (Scientific Electronic Library Online), Periódicos da CAPES (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior) e IBICT (Instituto Brasileiro de Informação em Ciência eTecnologia). Os resultados indicam que são muitas as dúvidas que perpassam a reestruturação dos sistemas educacionais, desde a gestão de sala de aula à do aprendizado, mas as demandas em sala de aula hoje requerem a quebra do currículo padrão e de adaptações curriculares para atender a contento esse público, além de um trabalho articulado entre o professor de ensino regular e o da Educação Inclusiva. Assim, a gestão da sala de aula, do conhecimento e do espaço físico devem ser adaptados para que esse alunado avance em sua aprendizagem.

Malakoplakia is an uncommon granulomatous disease that occurs in
immunocompromised individuals. It’s thought to be caused by macrophagic
bactericidial defect. We report a rare case of breast malakoplakia in a
pregnant 35 ears-old woman that mimicked malignancy.
Generalized inverses and the solutions of constructed equations
Authors: Peng Chunmei , Zhou Hainan , Wei Junchao
Published: July 2022

In this paper, by virtue of the properties of the generalized inverses of the
elements in rings with involution, we construct the related equations. By
discussing the solutions of these equations, the generalized invertible
elements are characterized.
Existence of mild solutions to semilinear fractional evolution equation using Krasnoselskii fixed point theorem
Authors: Ngoc Tran , Tuan Nguyen
Published: July 2022

This paper is devoted to study the existence and stability of mild solutions
for semilinear fractional evolution equations with a nonlocal final
condition. The analysis is based on analytic semigroup theory, Krasnoselskii
fixed point theorem, and a special probability density function. An
application to a time fractional diffusion equation with nonlocal final
condition is also given.
(m,∞)-expansive and (m,∞)-contractive commuting tuple of operators on a Banach space
Authors: Alshammari Hadi , Mahmoud Sid
Published: July 2022

For a d-tuple of commuting operators S := (S1,..., Sd) ? B[X]d, m ? N and
p ? (0,?), we define Q(p) m (S;u) := ? 0?k?m (-1)k (m k) (???Nd0 |?|
= k k!/? ||S?u||p). As a natural extension of the concepts of (m,p)-expansive and (m,p)-contractive for tuple of commuting operators, we
introduce and study the concepts of (m,?)-expansive tuple and
(m,?)-contractive tuple of commuting operators acting on a Banach space. We
say that S is (m,?)-expansive d-tuple (resp. (m,?)- contractive d-tuple)
of operators if Q(p)m (S;u) ? 0 ? u ? X and p ? ? (resp. Q(p)m (S;u) ?
0 ? u ? X and p ? ?) . These concepts extend the definition of
(m,?)-isometric tuple of bounded linear operators acting on Banach spaces
was introduced and studied in [13].
Double points and universal covers
Authors: Otera Daniele
Published: July 2022

In this note we study the double points set of a particular covering map of
an open manifold, and we present a new procedure for building universal
covering spaces of such manifolds. This is done by means of an arborescent
construction, starting from a presentation of the manifold as a non-compact
simplicial complex with pairwise identified faces. The proof uses the
so-called ?zipping theory? of Po?naru which helps the understanding of the
topology of the quotient manifold resulted from the combinatorial
presentation.
Integral operators on local Orlicz-Morrey spaces
Authors: Yee Tat-Leung , Cheung Ka-Luen , Ho Kwok-Pun
Published: July 2022

We establish a general principle on the boundedness of operators on local
Orlicz-Morrey spaces. As applications of this principle, we obtain the
boundedness of the Calder?n-Zygmund operators, the nonlinear commutators of
the Calder?n-Zygmund operators, the oscillatory singular integral
operators, the singular integral operators with rough kernels and the
Marcinkiewicz integrals on the local Orlicz-Morrey spaces.
On the inequality w(AB) ≤ c||A||w(B) where A is a positive operator

Published: July 2022

Abu-Omar and Kittaneh [Numerical radius inequalities for products of Hilbert
space operators, J. Operator Theory 72(2) (2014), 521-527], wonder what is
the smallest constant c such thatw(AB) ? c||A||w(B) for all bounded linear
operators A, B on a complex Hilbert space with A is positive. Here, w(?)
stands for the numerical radius. In this paper, we prove that c = 3?3/4.
Palindromic p-adic continued fractions
Authors: Ammous Basma , Dammak Lamia
Published: July 2022

The aim of this paper is to establish new transcendence criteria of p-adic
continued fractions. We prove that a p-adic number whose sequence of partial
quotients is bounded in Qp and begins with arbitrarily long palindromes is
either quadratic or transcendental.
Existence and controllability results for integrodifferential equations with state-dependent delay and random effects
Authors: Diop Amadou , Fall Mbarack , Diop Mamadou , Ezzinbi Khalil
Published: July 2022

The goal of this study is to investigate the existence and uniqueness of mild solutions, as well as controllability outcomes, for random integrodifferential equations with state-dependent delay. We prove the existence and uniqueness of mild solutions in the case where the nonlinear term is of the Carath?odory type and meets various weakly compactness conditions. Our research is based on Dardo?s fixed point theorem, M?nch?s fixed point theorem, a random fixed point with a stochastic domain, and Grimmer?s resolvent operator theory. Finally, an example is provided to demonstrate the outcomes that were obtained.
