It is known that if Lotka-Volterra operators, defined on the simplex Sm−1, satisfy f-monotonicity condition, then they are bijection of Sm−1. In the present paper, we consider a class of Lotka-Volterra operators defined on two dimensional simplex which are bijective, however, they are not f-monotone.Bijectivity of a Class of Lotka-Volterra Oper

Abstract: Pyrite (FeS2) oxidation in acid sulfate soil led to high acidity and aluminium (Al) and/or iron (Fe) toxicity to the plant. This problem causes nutrient deficiency and root inhibition, which retards plant nutrient uptake efficiency for growth. Plant-microbe interaction is one of the most important determining factors influencing nutrient

The study aims to compare the lignin extraction methods of OPEFB using different solvents; soda and dioxane solvent, and the reinforcement effects in polylactic acid (PLA) bio-composite. Different extraction method has been found to produce lignin with different properties and purity. The extraction yield also highly dependent on the types of solve

Objectives: This study aimed to profile the cognitive aging research landscape from 1956 to 2021. Methods: A total of 3,779 documents were retrieved from the Scopus database for the bibliometric analysis and network visualization. By comparing each keyword’s overall connection strength (centrality), frequency (density), and average year of public

In present paper, we study dynamical systems generated by a class of Lotka–Volterra operators. It is proved that such class of operator has non-ergodic property.ISSN 1995-0802, Lobachevskii Journal of Mathematics, 2022, Vol. 43, No. 9, pp. 2591–2598. c/circlecopyrtPleiades Publishing, Ltd., 2022.

Thermochemical gaseous nitriding is a surface modification process used for specific applications especially wear resistance components. The work aims to develop a formation of a modified surface layer on duplex stainless steel (DSS) using a gaseous thermochemical nitriding process using a tube furnace. This study investigated the effects of the ni

This research investigates the long-run and short-run effects of technological advancements on environmental degradation in ASEAN countries. The research was conducted using Pooled Mean Group (PMG) panel data estimation methodologies, and the data set used in this study includes annual data from 2000 to 2019. Results revealed that the development o

A large amount of crude palm oil production in South East Asia (SEA) is causing the production of a vast amount of agricultural waste from the palm oil industry. Oil palm empty fruit bunch (OPEFB) is one of the agricultural wastes with high lignocellulose content. Lignin is the lignocellulose component that has the potential to be used as fuel for

The movement and mobility of human on the earth always continuously occurred due to of the needs as a human being. The movement creates relationship between human emotional values with visited places. However, tourists nowadays face limitation in their movement of journey while visiting plenty of attractions especially in Muar Royal Town, Johor. Th

BACKGROUND AND AIM: Ustekinumab was licenced for treatment of moderate to severe Crohn disease (CD) in Malaysia since March 2020 while Infliximab is a well-established treatment for moderate to severe CD. Our objective is to look at real- world data on efficacy, safety and persistence of Ustekinumab versus Infliximab in our population. METHODS: Thi
