Abstract The COVID-19 pandemic has resulted in a change food demand. In Central Java, during the (2021), proportion of expenditure on grain group was higher than 2020; meanwhile, ready-to-eat decreased. This study aims to analyze pattern consumption carbohydrate sources, influencing factors, and elasticity households Java before pandemic. uses data from National Socio-Economic Survey (Susenas) ...

the aim of this paper is to introduce and study set- valued homomorphism on lattices and t-rough lattice with respect to a sublattice. this paper deals with t-rough set approach on the lattice theory. the result of this study contributes to, t-rough fuzzy set and approximation theory and proved in several papers. keywords: approximation space; lattice; prime ideal; rough ideal; t-rough set; set...

Purpose – The purpose of this paper is to investigate dynamic food demand in urban China, with use of a complete dynamic demand system DLES-LA/DAIDS, which pushes forward the techniques of demand analysis. Design/methodology/approach – We employ a transitionary demand process and develop a new approach of complete demand system with a two-stage dynamic budgeting: an additively separable dynamic...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...
