Background: Obstacles are found during the epistemological construction of mathematical concepts research, aiming to contribute to the Didactics of Mathematics through a study of Padovan sequence.  Objectives: describe elements of a systematic study,... see more

Here we find the Padovan and Perrin numbers that are concatenations of two terms of the other sequence. We also find the intersection between these ternary sequences.

It is known that over 90% of oil, gas and gas condensate in Azerbaijan is produced from Productive Series (PS) of the Early Pliocene. In this respect, the detailed study of Pro- ductive Series deposits and their evolution conditions has a special value. C... see more

Background & Objectives: Serous ovarian carcinoma (SOC) is characterized by extreme genomic instability, chromosomal rearrangements and copy number variations (CNVs) leading to the development of early metastasis and chemo-resistance. The present stud... see more

Limosilactobacillus fermentum is a promising probiotic with several documented health benefits. LAB1 is an antagonistic L. fermentum strain isolated from borhani, a traditional South Asian beverage prepared from dairy and plant ingredients. Here, I presen... see more

Let (s2(n))8n=0(s_2(n))_{n=0}^\infty denote Stern's diatomic sequence. For n=2n\geq 2, we may view s2(n)s_2(n) as the number of partitions of n-1n-1 into powers of 22 with each part occurring at most twice. More generally, for integers b,n=2b,n\geq 2, let... see more

A ausência do estudo da Sequência Padovan no ensino de História da Matemática nos cursos de licenciatura motivou a realização desta pesquisa, dada a particularidade provocante de suas relações. Assim, o objetivo deste trabalho é apresentar uma proposta di... see more

In the implementation of the teaching and learning process, the use of learning media is still not optimally applied, besides seeing the obstacles experienced by students in learning mathematics, especially the material for rows and Series. So, a solution... see more

Introduction. Deoxyribonucleic acid (DNA) is not a random sequence of four nucleotides  combinations: comprehensive reviews [1, 2] persuasively shows long- and short-range correlations in DNA, periodic properties and correlations structure of sequenc... see more
