Human resource problem that lies in the achievement of organizational empowerment Sociological Reading

The success of most international companies is due to the harmony between these countries in terms of cultures, goals and the desire of customers. They are interested in employee awareness, empowerment, vision, satisfaction and culture that enable them to achieve the goals of the institution. When the employee is satisfied, it leads to greater harmony between individuals. Through dealing with them and meeting them on the one hand and dealing with employees in the management and the positive feeling and role played by him on the other hand.

Mechanical Behavior of High-Performance Concrete under Thermal Effect

Several studies on the behavior of concrete at high temperatures are the subject of recent concerns, following the latest fires in various European tunnels. In these extreme conditions, significant degradations of concrete structures can be observed (peeling, cracking, breaking of the structure). A priori prediction of concrete behavior during this type of stress is therefore essential and is not possible without a good understanding of the different mechanisms of concrete damage at high temperatures. These mechanisms are often considered as the main causes of cracking and peeling of concrete subjected to high temperatures. Therefore, a fire can strongly modify the behavior of concrete and jeopardize the stability of concrete. In case of fires, it is necessary to know the instantaneous and residual behavior of concrete subjected to temperatures up to 1000°C. In this work we present a study of the mechanical performance of high-temperature high-performance concrete (HPC) exposed to four maximum temperatures, 200, 400, 600, and 900°C. The results obtained show that the mechanical strength at 28 days increases with the degree of temperature compared with that measured at 20°C. On the contrary, a clear decrease is observed between 600 and 900°C

On the Complexity of Reconfiguration of Clique, Cluster Vertex Deletion, and Dominating Set

A graph problem P is a vertex-subset problem if feasible solutions for P consist of subsets of the vertices of a graph G. The st-connectivity problem for a vertex-subset problem P takes as input two feasible solutions S_s and S_t, and determines if there is a sequence of recon figuration steps that can be applied to transform S_s into S_t, such that each step results in a feasible solution of P of size bounded by k and each step is a vertex addition or deletion. For most NP-complete problems, this problem has been shown to be PSPACE-complete, while for some problems in P, this problem could be either in P or PSPACE-complete. However, knowing the complexity of a decision problem does not directly imply the complexity of its st-connectivity problem. Therefore, it is natural to ask whether we can fi nd a connection between the complexity of a decision problem and its st-connectivity problem when restricted to graph classes. This question motivated us to study the st-connectivity problems Clique Reconfiguration and Dominating Set Reconfiguration, whose decision problems' complexity for restricted graph classes is extensively studied, to get a better understanding of the boundary between polynomial-time solvable and intractable instances of these reconfi guration problems. Furthermore, we study the Cluster Vertex Deletion Reconfiguration problem, a problem whose decision problem is related to the Clique problem, to fi nd whether there is a connection between the complexity of this problem and the Clique Reconfiguration problem. Following are the main contributions of this thesis. First, we show that the Clique Re- configuration problem is linear-time solvable for paths, trees, bipartite graphs, chordal graphs, and cographs. Then, we prove that the Cluster Vertex Deletion Reconfiguration problem is linear-time solvable for paths and trees, and that it is NP-hard on bipartite graphs, and PSPACE-complete in general. Finally, we determine that the Dominating Set Reconfiguration problem is linear-time solvable for paths, cographs, trees, and interval graphs. Furthermore, we show that the problem is PSPACE-complete for general graphs, bipartite graphs, and split graphs

Survey and diversity of grapevine pinot gris virus in algeria and comprehensive high-throughput small rna sequencing analysis of two isolates from vitis vinifera cv. Sabel revealing high viral diversity

Grapevine Pinot gris virus (GPGV) is a putative causal agent of grapevine leaf mottling and deformation disease that has been reported worldwide throughout the grapevine-growing regions. Fifty-four grapevines collected from five Algerian grapevine-growing regions were tested for the presence of GPGV in phloem tissues. Eight of the tested grapevines were infected by GPGV. Viromes of two selected Vitis vinifera cv. Sabel grapevines infected by GPGV and showing virus-like symptoms were analyzed by small RNA sequencing. Phylogenetic analyses of the partial coding sequence (cds) of the RNA-dependent RNA polymerase (RdRp) domain showed that all Algerian GPGV isolates were grouped with some already-described asymptomatic isolates. This study provides the first survey of the occurrence of GPGV in Algeria. Moreover, Grapevine fleck virus, Grapevine rupestris stem pitting-associated virus, Grapevine virus B, Grapevine rupestris vein feathering virus, Hop stunt viroid and Grapevine yellow speckle viroid 1 were detected in Algeria for the first time.O

Effects of Crossover Operators on Genetic Algorithms for the Extraction of Solar Cell Parameters from Noisy Data

This study analyzed the accuracy of solar cell modeling parameters extracted from noisy data using Genetic Algorithms (GAs). Three crossover operators (XOs) were examined, namely the Uniform (UXO), Arithmetic (AXO), and Blend (BXO) operators. The data used were an experimental benchmark cell and a simulated curve where noise levels (p) from 0 to 10% were added. For each XO, the analysis was carried out by running GAs 100 times and varying p and population size (Npop). Simulation results showed that UXO and AXO suffered from premature convergence and failed to provide parameters with good precision even with very high Npop, although they provided good fitting. In all analyzed cases, BXO outperformed UXO and AXO and the results showed that it can compete with the most efficient methods. For the benchmark curve, BXO reproduced the best RMSE found in the literature (0.7730062 mA) while providing the exact values of the parameters and a very low RMSE (1E-13) for the clean curve (p=0). For noisy curves, the errors of the extracted parameters were smaller than 10% for p lower than or equal to 6%. For higher values of p, the errors were smaller than 30%

Influence of Local Sand on the Physicomechanical Comportment and Durability of High Performance Concrete

This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially replaced by the SD (<2/3). However, a high content of SD (>1/3) additional quantities of water is needed to meet the workability properties. The mechanical strengths decrease by adding the SD to CS, but they reach acceptable values with CS in moderate dosages. The HPC performances are significantly better than the control concrete made up with the same aggregates. The specification tests of durability show that the water absorbing coefficients by capillarity increase after adding SD to the CS

Phylogeny of Neofusicoccum species associated with grapevine trunk diseases in Algeria, with description of Neofusicoccum algeriense sp. nov.

During a study of Botryosphaeriaceae species associated with grapevine trunk diseases in North Algeria, a collection of 67 Neofusicoccum-like strains were isolated from three cultivars (Cinsaut, Alphonse Lavallée and Cardinal) from two different locations. Based on morphology and DNA sequence data (ITS and TEF-1α), four species were identified. Of these, Neofusicoccum parvum, N. mediterraneum and N. australe are known, while N. algeriense is described here as new. These species are reported for the first time from Algeria. In this study, relationships between vascular lesions and Neofusicoccum species isolated were highlighted. The Neofusicoccum spp. were most often isolated from wedge-shaped and yellow soft wood rots and more rarely from central brown necrosis and black streaking. Neofusicoccum parvum was the most frequently isolated (48 isolates) followed by N. algeriense (four), while N. mediterraneum and N. australe were each found only once
