Published: December 2021

Поняття "диференціювання напівкільця" традиційно визначають як адитивне відображення, яке задовольняє правило Лейбніца, тобто відображення δ: R →R називають диференціюванням напівкільця R, якщо δ (a + b) = δ (a)+δ (b) і δ (ab) = δ (a) b + aδ (b) для будь-яких a,b ∈ R. Поняття квазіпервинний ідеал" було вперше введено в комутативних диференціальних кільцях, тобто комутативних кільцях, які розглядаються разом із заданим на них диференціюванням, як диференціальний ідеал, максимальний серед диференціальних ідеалів, які не перетинаються із деякою мультиплікативно-замкненою підмножиною кільця. Піднапівмодуль P напівмодуля M називають первинним, якщо для будь-якого ідеалу I напівкільця R та будь-якого піднапівмодуля N напівмодуля M з IN ⊆ P випливає N ⊆ P або I ⊆ (P : M). Диференціальний піднапівмодуль P напівмодуля M називають "диференціально-первинний піднапівмодуль", якщо для будь-яких r ∈ R, m ∈ M, k ∈ N0, rm(k) ∈ P випливає, що r ∈(P : M) або m ∈P.
Ця стаття присвячена дослідженню понять "диференціальний піднапівмодуль", "диференціально-первинний піднапівмодуль", "квазіпервинний піднапівмодуль" в диференціальних напівмодулях (які означаються як напівмодулі разом із диференціюванням, заданому на них, яке узгоджується з відповідним диференціюванням напівкільця). Метою статті є дослідити деякі властивості таких піднапівмодулів, показати взаємозв'язки між "квазіпервинними піднапівмодулями" та "диференціально-первинними" "піднапівмодулями" у випадку диференціальних напівмодулів, що задовольняють умову обриву зростаючих ланцюгів диференціальних піднапівмодулів. Стаття складається з двох основних частин. У першій частині автори досліджують деякі властивості диференціальних піднапівмодулів та відповідних диференціальних ідеалів, а також наводить деякі приклади таких піднапівмодулів. У другій частині статті розглядаються ланцюги зв'язки, що існують між поняттями "квазіпервинний піднапівмодуль" та "диференціально-первинний піднапівмодуль". Встановлено, що "диференціальний піднапівмодуль" N напівмодуля M є "диференціально-первинний піднапівмодуль" тоді і тільки тоді, коли N є "квазіпервинний піднапівмодуль" диференціального напівмодуля M, який задовольняє умову обриву зростаючих ланцюгів диференціальних піднапівмодулів.

В даній статті для комплексної алгебри Лі sl3 запропонована явна формула знаходження кратності ваги незвідного зображення Γλ, яке визначається старшою вагою λ = (a,b). Множина всіх ваг Λ такого зображення утворює групове кільце Z[Λ] з мультиплікативним базисом e(μ),μ ∈ Λ. Характер зображення Char Γλ є елементом Z[Λ], коефіцієнти якого і є шуканими кратностями. Головна ідея обчислень полягає у специфікації базису e(μ) = xμ1yμ2 групового кільця Z[Λ]. Це дало можливість представити характер Char Γλ незвідного Γλ зображення як многочлен Шура $s_{a,b}\left(x,\dfrac{y}{x}, \dfrac{1}{y} \right)$ від двох змінних $x,y$ . Як наслідок ми виразити коефіцієнти цього многочлена через прості функції, які легко обчислюються за лінійний час. Ключову роль в обчисленні зіграли знайдені явно коефіцієнти розкладу ряду$$\Delta=\dfrac{1}{\left( {y}^{2}-x \right) \left(1- yx \right) \left( y-{x}^{2} \right)},$$ в термінах функції
$$c(n,k)= \left \{\begin{array}{l}\min(n{-}k+2,k) , 1 \leq k \leq n+1, \\\\0, \text{ {\rm в іншому випадку.} }\end{array}\right.$$
Understanding Purchase Intention for Different Personality Traits in Social Networking Services
Authors: Ali Azrin 
Published: December 2021

What prompts users to readably purchase online compared to others is a beneficial insight for successful marketing campaigns. Purchase intention forecasts actual purchase act thus is desirable to be scrutinised. Furthermore, in social networking services settings, ample factors surface to observe purchase intentions from the user’s standpoint. While there are many facets to an individual makeup, understanding personality traits could be an excellent interplay in explaining purchase intention. The Big Five Factor Model (BFM) is utilised to predict the effect of personality traits in the aspect of business, specifically in the angle of purchase intention in social networking services (SNS). Personality traits (N=133) from the Big Five Model were found to be significant for SNS users’ using multiple regression analysis. Descriptive analyses were included to interpret the data. The value of this study showed that as a group, personality traits were significant on purchase intention, and proved that different versions of a similar message could be churned in a campaign to maximise conversion. The findings can fine-tune marketers’ way of handling different types of messages conveyed in SNS, and this research empirically investigated different personality types drawing from Big Five Model to understand purchase intention in SNS.

Published: December 2021

In this study, two systems of bio-ceramic coating (45S5 bioactive glass and hydroxyapatite) were used in order to compare between them for biomedical applications. Each system consists from two layers of coating done by electrophoretic deposition (EPD) technique on 316L stainless steel material as substrate. Two types of biopolymer were used (Chitosan with Gelatin) as first layer of coating. Taguchi approach with L9 array was used in order to choose the best conditions (concentrations, voltage and time) for coating layers. Each system consists of two layer (biopolymer (first layer) and bioceramic (second layer)) materials. The optimum parameters for first layer of biopolymer was (3g/L concentration, 20 voltage and 3 minute) while optimum parameter for second layer (6g/L concentration, 30 voltage and 1 minute) for two bioceramic group. Zeta potential test were employed to measure suspensions stability. The tape test method was used to evaluate the adhesion between substrate and coating layers, the results show that the percentage of removal area for optimum coating layer (biopolymer, 45S5 BG and HA 8.06%, 10.668%, 6.23% subsequently). XRD inspection was used for identify the phases of coating layers. The Cyclic polarization test was used for evaluation of pitting corrosion resistance, the results show all layers gives good corrosion resistance but 45S5BG gives the best corrosion resistance when compared with HA system.

Published: December 2021

Abstract
Session centered recommender systems has emerged as an interesting and challenging topic amid researchers during the past few years. In order to make a prediction in the sequential data, prevailing approaches utilize either left to right design autoregressive or data augmentation methods. As these approaches are used to utilize the sequential information pertaining to user conduct, the information about the future context of an objective interaction is totally ignored while making prediction. As a matter of fact, we claim that during the course of training, the future data after the objective interaction are present and this supplies indispensable signal on preferences of users and if utilized can increase the quality of recommendation. It is a subtle task to incorporate future contexts into the process of training, as the rules of machine learning are not followed and can result in loss of data. Therefore, in order to solve this problem, we suggest a novel encoder decoder prototype termed as space filling centered Recommender (SRec), which is used to train the encoder and decoder utilizing space filling approach. Particularly, an incomplete sequence is taken into consideration by the encoder as input (few items are absent) and then decoder is used to predict these items which are absent initially based on the encoded interpretation. The general SRec prototype is instantiated by us employing convolutional neural network (CNN) by giving emphasis on both e ciency and accuracy. The empirical studies and investigation on two real world datasets are conducted by us including short, medium and long sequences, which exhibits that SRec performs better than traditional sequential recommendation approaches.

Published: December 2021

Abstract
Let R be a commutative ring with nonzero identity. Let 𝒥(R) be the set of all ideals of R and let δ : 𝒥 (R) → 𝒥 (R) be a function. Then δ is called an expansion function of ideals of R if whenever L, I, J are ideals of R with J ⊆ I, we have L ⊆ δ (L) and δ (J) ⊆ δ (I). Let δ be an expansion function of ideals of R. In this paper, we introduce and investigate a new class of ideals that is closely related to the class of δ -primary ideals. A proper ideal I of R is said to be a 1-absorbing δ -primary ideal if whenever nonunit elements a, b, c ∈ R and abc ∈ I, then ab ∈ I or c ∈ δ (I). Moreover, we give some basic properties of this class of ideals and we study the 1-absorbing δ-primary ideals of the localization of rings, the direct product of rings and the trivial ring extensions.

Authors: Juncu Gh. , Popa C. , Sarbu Gh. 
Published: December 2021

Abstract
This work continues our previous analysis concerning the numerical solution of the multi-component mass transfer equations. The present test problems are two-dimensional, parabolic, non-linear, diffusion- reaction equations. An implicit finite difference method was used to discretize the mathematical model equations. The algorithm used to solve the non-linear system resulted for each time step is the modified Picard iteration. The numerical performances of the preconditioned conjugate gradient algorithms (BICGSTAB and GMRES) in solving the linear systems of the modified Picard iteration were analysed in detail. The numerical results obtained show good numerical performances.

Authors: Serôdio Rogério , Beites P. D. , Vitória José 
Published: December 2021

Abstract
In the present work it is proved that the zeros of a unilateral octonionic polynomial belong to the conjugacy classes of the latent roots of an appropriate lambda-matrix. This allows the use of matricial norms, and matrix norms in particular, to obtain upper and lower bounds for the zeros of unilateral octonionic polynomials. Some results valid for complex and/or matrix polynomials are extended to octonionic polynomials.

Abstract
Let R be a commutative ring with non-zero identity and M be a unitary R-module. The goal of this paper is to extend the concept of 1-absorbing primary ideals to 1-absorbing primary submodules. A proper submodule N of M is said to be a 1-absorbing primary submodule if whenever non-unit elements a, b ∈ R and m ∈ M with abm ∈ N, then either ab ∈ (N :
RM) or m ∈ M − rad(N). Various properties and chacterizations of this class of submodules are considered. Moreover, 1-absorbing primary avoidance theorem is proved.

Introdução: Literacia em saúde é um tema de popularidade crescente face à relevância e impacto que tem nos re- sultados clínicos. Existem diversas ferramentas de avaliação de literacia em saúde sendo o European Health Literacy Sur- vey Questionnaire (HLS-EU) o mais recentemente aplicado e validado. Graus de literacia consideradas problemáticas ou insuficientes estão associadas a incidência e gravidade pior de doenças, taxas de hospitalização e morbi-mortalidade superior. O objetivo foi aferir o grau de literacia em saúde relativamente aos cuidados de saúde.Material e Métodos: Aplicação da versão portuguesa do questionário HLS-EU (HLS-PT) aos doentes internados ao cuidado da medicina interna. Incluídos todos os doentes internados ao cuidado da medicina interna, tendo-se excluído de doentes cognitivamente e clinicamente incapazes de responder ao questionário.
Resultados: Foram inquiridos 64 doentes. A amostra era maioritariamente do sexo masculino (57%) com média de idade 71 anos, reformado (71,8%) e com grau de escolaridade baixa (56,2% com formação académica até 1o ciclo). A maioria (68,7%) tinha grau de literacia em saúde problemática ou insuficiente quanto aos cuidados de saúde.
Conclusão: Apesar de se reconhecer que, tanto o ambiente da aplicação do questionário como as características demográficas deste estudo serem diferentes do estudo nacional e europeu, revela-se um resultado preocupante da literacia em saúde de indivíduos hospitalizados com doenças crónicas.
