abstract soil contamination by heavy metals is yet one of the most important environmental concerns. among heavy metals, nickel and cadmium have dangerous influences on human, animals and plants. the objective of this study was to derive a new model for simultaneous phytoextraction of ni and cd from contaminated soils. consequently, a macroscopic model was derived by combining yield reduction f...

We introduce an inheritance property and related table lookup structures applicable to simplified evaluation of the modular operations “multiplicative inverse”, “discrete log”, and “exponential residue” in the particular modulus 2. Regarding applications, we describe an integer representation system of Benschop for transforming integer multiplications into additions which benefits from our tabl...

People often overestimate probabilities of conjunctive events. The authors explored whether the accuracy of conjunctive probability estimates can be improved by increased experience with relevant constituent events and by using memory aids. The first experiment showed that increased experience with constituent events increased the correlation between the estimated and the objective conjunctive ...

We propose a simple approach, the multiplicative background correction, to solve a perplexing problem in spotted microarray data analysis: correcting the foreground intensities for the background noise, especially for spots with genes that are weakly expressed or not at all. The conventional approach, the additive background correction, directly subtracts the background intensities from foregro...

Various scholars have lately employed a wide range of strategies to resolve specific types symmetrical fractional differential equations. In this paper, we propose new identity for multiplicatively differentiable functions; based on identity, establish some multiplicative Bullen-type inequalities convex functions. Some applications the obtained results are given.

This paper reports about a large-scale longitudinal field experiment investigating the effects of online mathematics mini-games on secondand third-graders’ multiplicative reasoning abilities. The study included students in regular primary education (n = 719) and special primary education (n = 81). There were three experimental conditions: playing multiplicative mini-games at school, at home, an...

Multiplicative linear secret sharing is a fundamental notion in the area of secure multiparty computation (MPC) and, since recently, in the area of two-party cryptography as well. In a nutshell, this notion guarantees that “the product of two secrets is obtained as a linear function of the vector consisting of the coordinate-wise product of two respective share-vectors”. This paper focuses on t...

This study aims to determine the distribution of percentage proportional reasoning tasks in comparison chapter task series book MANDIRI (Mengasah Kemampuan Diri) Mathematics Grade VII Curriculum 2013, Revised Edition, 2016 Publisher Erlangga, written by Kurniawan. research is a qualitative using descriptive approach. The data from are documented and then analyzed based on indicators each level ...

We use a general treatment of both information-theoretic and cryptographic settings for Multi-Party Computation (MPC), based on the underlying linear secret sharing scheme. Our goal is to study the Monotone Span Program (MSP), which is the result of local multiplication of shares distributed by two given MSPs as well as the access structure that this resulting MSP computes. First, we expand the...

In this paper, we consider flat epimorphisms of commutative rings [Formula: see text] such that, for every ideal which text], the quotient ring is semilocal Krull dimension zero. Under these assumptions, show that projective R-module U does not exceed 1. We also describe Geigle–Lenzing perpendicular subcategory in text]. Assuming additionally and all are perfect, R-modules U-strongly flat. Thus...
