FAULT-TOLERANT METRIC DIMENSION OF CIRCULANT GRAPHS
Authors: Seyedi Narjes , Maimani Hamid Reza 
Published: March 2021

A set $W$ of vertices in a graph $G$ is called a resolving setfor $G$ if for every pair of distinct vertices $u$ and $v$ of $G$ there exists a vertex $w \in W$ such that the distance between $u$ and $w$ is different from the distance between $v$ and $w$. The cardinality of a minimum resolving set is called the metric dimension of $G$, denoted by $\beta(G)$. A resolving set $W'$ for $G$ is fault-tolerant if $W'\setminus \left\lbrace w\right\rbrace $ for each $w$ in $W'$, is also a resolving set and the fault-tolerant metric dimension of $G$ is the minimum cardinality of such a set, denoted by $\beta'(G)$. The circulant graph is a graph with vertex set $\mathbb{Z}_{n}$, an additive group of integers modulo $n$, and two vertices labeled $i$ and $j$ adjacent if and only if $i -j \left( mod \ n \right) \in C$, where $C \in \mathbb{Z}_{n}$ has the property that $C=-C$ and $0 \notin C$. The circulant graph is denoted by $X_{n,\bigtriangleup}$ where $\bigtriangleup = \vert C\vert$. In this paper, we study the fault-tolerant metric dimension of a family of circulant graphs $X_{n,3}$ with connection set $C=\lbrace 1,\dfrac{n}{2},n-1\rbrace$ and circulant graphs $X_{n,4}$ with connection set $C=\lbrace \pm 1,\pm 2\rbrace$.

Authors: Çinar Muhamed , Et Mikail 
Published: March 2021

In this paper, we introduce and examine the concepts of Delta^m pointwise and Delta^m uniform statistical convergence of order alpha for double sequences of real valued functions. Also we give the concept of Delta^m statistically Cauchy sequence for double sequences of real valued functions and prove that it is equivalent to Delta^m pointwise statistical convergence of order alpha for double sequences of real valued functions. Also some relations between S_alpha^ 2(Delta^m,f )-statistical convergence and strong [w_p^2]_alpha (Delta^m,f )-summability are given.

Secondary metabolites and mycorrhizal symbiosis play important roles in the adaptation of plants to environmental conditions, but mycorrhizal symbiosis favours also accumulation of secondary metabolites. Our objective was to study effect of interaction between mycorrhization and water deficiency on morphological parameters, phenolic compound concentration in Lupinus albus and to perform an evaluation of the antioxidant potential of methanolic extract of this plant. Plants of L. albus were subjected to three levels of water defficiency (80, 50 and 30% of field capacity). Half of the plants in each treatment were inoculated with arbuscular mycorrhizal fungi. Total concentrations of polyphenols, flavonoids, and condensed tannins were measured, and antioxidant potential of methanolic extracts from leaves and roots of white lupin plants was evaluated. In general, mycorrhizal plants of L. albus had better growth indices in all watering regimes in comparison to non-mycorrhizal plants. The concentrations of phenolic compounds were maximal in the leaf extracts from L. albus plants inoculated with arbuscular mycorrhizal fungi grown under 30% of field capacity water regime, and in root extract of non-inoculated plants grown under 30% of field capacity. Methanolic extracts of all plants showed good antioxidant activity, with higher values in mycorrhizal drought-stressed plants.

Published: March 2021

The accelerated aging test is efficient for evaluating the seed vigor of many species, but there are few studies on forest tree species. The aim of this study was to determine the adequate exposure time of Piptadenia moniliformis Benth. seeds to the accelerated aging test in order to evaluate the vigor of seeds classified by color and size. Ten sub-lots were obtained by separating the seeds into two tegument colors (light and dark) and five size classes (11, 12, 13, 14, and 15), using round wire sieves. Before the accelerated aging (AA) test, the seeds were treated with concentrated sulfuric acid for 20 minutes to overcome dormancy. Next, the sub-lot seeds underwent different aging times (0, 24, 48, 72, 96 and 120 hours) at 45 ºC. The AA test, conducted at 45 ºC for 72 hours, is adequate to evaluate the quality of P. moniliformis seeds, in terms of color and size.

Socio-Demographic Variables of Work Engagement, Psychological Capital and Turnover Intention among South African Teachers
Authors: Mvana Siyamthanda Wendy , Louw Larisa 
Published: March 2021

This study sought to empirically assess whether the socio-demographic variables (age, race, gender, marital status, educational level, years employed, employment status, and home language) of teachers predict their work engagement, psychological capital and turnover intention. A quantitative study was conducted using a non-probability, convenience sampling method on teachers working in the Tshwane South District in Gauteng, South Africa (N = 208). Biographical data were collected. Questionnaires of the Utrecht Work Engagement Scale, the Turnover Intention Scale, and Psychological Capital were used in the data collection. The results showed that education qualifications, race, tenure, and the age of high school teachers contribute when explaining their work engagement, psychological capital and turnover intention. The sample was predominantly characterised by African teachers, resulting in the under-representation of other races, and the size of the sample was not large enough to generalise the findings. These findings add valuable knowledge to the body of research and provide new insights that are aimed at enhancing the retention of high school teachers in underdeveloped countries. It is recommended that future research obtain a larger and a more representative sample to increase external validity.

Published: March 2021

ABSTRACT Competition between atmospheric moisture and volatile organic compounds (VOCs) for an adsorbent’s sites can significantly impact its VOC removal efficiency. The development of moisture-tolerant adsorbents is essential to address this issue. A vapor phase deposition process using polydimethylsiloxane (PDMS) has created a hydrophobic form of the highly porous, normally hydrophilic, MOF MIL-101. After optimizing the PDMS vapor deposition time and molecular weights, hydrophobicity index calculations verified the improved hydrophobicity of the coated MOF (MIL-PDMS-Sigma-0.25) over its pristine form. The surface area, pore volume as well as single component vapor adsorption of water and toluene capacities were also preserved, resulting to similar performance to MIL-101. Toluene-water vapor co-adsorption experiments were conducted at 40% RH using two toluene concentrations: 0.5% P/P0 and 10% P/P0, mimicking environmental VOC and industrial concentrations, respectively. At 0.5% P/P0, MIL-PDMS-Sigma-0.25 exhibited 60% higher adsorption capacity and twice the rate of toluene capture relative to pristine MIL-101, as well as a 3-fold higher toluene uptake relative to a commercial activated carbon. Preliminary adsorbent regeneration experiments confirm the stability and performance of MIL-PDMS-Sigma-0.25. Using a simple vapor phase modification, this new MOF-composite material offers superior competitive toluene vapor uptake in humidified real-world conditions at VOC concentrations.

Published: March 2021

In spite of being spin-forbidden, some enzymes are capable of catalyzing the incorporation of O2 (3Σ−g) toorganic substrates without needing any cofactor. It has been established that the process followed by theseenzymes starts with the deprotonation of the substrate forming an enolate. In a second stage, the peroxidationof the enolate formation occurs, a process in which the system changes its spin multiplicity from a triplet stateto a singlet state. In this article, we study the addition of O2 to enolates using state-of-the-art multi-referenceand single-reference methods. Our results confirm that intersystem crossing is promoted by stabilization ofthe singlet state along the reaction path. When multi-reference methods are used, large active spaces arerequired, and in this situation, Semistochastic Heat-Bath Configuration Interaction (SHCI) emerges as apowerful method to study these multi-configurational systems and is in good agreement with LCCSD(T)when the system is well-represented by a single-configuration.
