    In this paper, we introduce the goal programming in neutrosophic environment. The degrees of acceptance, indeterminacy and rejection of objectives are simultaneously considered. We propose two models for solving Neutrosophic Goal Programming Problem (NGPP), at one hand aiming to minimize the sum of the deviation (the I st model), and at the other hand, transforming NGPP into a crisp programming model, using truth membership, indeterminacy membership, and falsity membership functions (the II nd model). Finally, an industrial design problem is given to illustrate the efficiency of the proposed models. The obtained results of the Ist model and of the IInd model are compared with other methods

    Cyperus species represent a group of cosmopolitan plants used in folk medicine to treat several diseases. In the current study, the phytochemical profile of Cyperus laevigatus ethanolic extract (CLEE) was assessed using UPLC-QTOF–MS/MS. The protective effect of CLEE at 50 and 100 mg /kg body weight (b.w.) was evaluated on hepatorenal injuries induced by thioacetamide (100 mg/kg) via investigation of the extract’s effects on oxidative stress, inflammatory markers and histopathological changes in the liver and kidney. UPLC-QTOF–MS/MS analysis of CLEE resulted in the identification of 94 compounds, including organic and phenolic acids, flavones, aurones, and fatty acids. CLEE improved the antioxidant status in the liver and kidney, as manifested by enhancement of reduced glutathione (GSH) and coenzyme Q10 (CoQ10), in addition to the reduction in malondialdehyde (MDA), nitric oxide (NO), and 8-hydroxy-2′-deoxyguanosine (8OHdG). Moreover, CLEE positively affected oxidative stress parameters in plasma and thwarted the depletion of hepatorenal ATP content by thioacetamide (TAA). Furthermore, treatment of rats with CLEE alleviated the significant increase in plasma liver enzymes, kidney function parameters, and inflammatory markers. The protective effect of CLEE was confirmed by a histopathological study of the liver and kidney. Our results proposed that CLEE may reduce TAA-hepatorenal toxicity via its antioxidant and anti-inflammatory properties suppressing oxidative stress

    Application of date palm leaves compost and plant growth promoting rhizobacteria for controlling faba bean root rot disease in New Valley, Egypt

    This study was designed to investigate the effect of date palm leaves compost (DPLC) individually and/or in combined with plant growth promoting rhizobacteria (PGPR) for controlling faba bean root rot disease caused by Rhizoctonia solani and Fusarium solani under greenhouse and field conditions. The obtained data indicate that DPLC at different concentrations significantly decreased root rot incidence either under artificial infection in pot or natural infection in field as well as increased growth and yield parameters during growing season 2013-2014. Date palm leaves compost at 8 ton/ feddan (feddan = 1.038 acres) recorded the highest protection against root rot disease and gave the highest increased of plant growth and yield parameters. On the other hand, PGPR viz. Bacillus megaterium, B. cereus and Pseudomonas fluorescens individually or mixed significantly decreased root rot incidence under greenhouse and field conditions. The mixed of PGPR strains significantly suppressed the diseases more than used alone of them. Plant growth promoting rhizobacteria increased efficacy of DPLC for controlling root rot disease in faba bean more than the applied of DPLC or PGPR alone under greenhouse and field conditions during both tested seasons as well as increased of nodulations, growth and yield parameters. The application mixed of PGPR strains and DPLC at 8 ton/feddan recorded the highest reduction of root rot incidence and increase of nodulations, growth and yield parameters during both growing seasons. 

    A Hybrid Flower Pollination Algorithm with Tabu Search for Unconstrained Optimization Problems

    Get PDF
    Flower pollination algorithm (FPA) is a novel metaheuristic optimization algorithm with quick convergence, but its population diversity and convergence precision can be limited in some problems. In order to enhance its exploitation and exploration abilities, in this paper a novel hybrid flower pollination algorithm with Tabu Search (TS-FPA) has been applied to unconstrained optimization problems. TS-FPA is validated by ten benchmark functions. The results show that the proposed algorithm is able to obtained accurate solution, and it also has a fast convergence speed and a high degree of stability

    RELATIVE POWER DISTRIBUTIONS IN OMNIGUIDING PHOTONIC BAND-GAP FIBERS

    No full text
    Using Bloch formulations, an analysis is presented of the confinement of power in omniguiding photonic band-gap fibers of different dimensional values. Results are compared for four-layer and eight-layer fibers. Power peaks are observed that correspond to different propagation modes. Power patterns are found to be fairly smoothly matched at the different layer interfaces, which confirm the validity of the analytical approach

    Dynamics of phase space quasi-probability coherence of one of two moving atoms trapped in a cavity coherent field

    No full text
    This study explores the dynamics of atomic mixedness and phase space quasi-probability information of one of two moving atoms trapped in a cavity filled by a coherent field. The atom-photon interactions are considered with the resonance case through nonlinear intensity-dependent coupling. We investigate the impacts of the atom-photon and atomic motion couplings on the dynamics of the atomic Wehrl entropy's mixedness and phase space Husimi distribution information. By helping Wehrl entropy's mixedness dynamics, the dynamics of acceleration and enhancement of the generation of the atomic phase space quasi-probability coherence are examined, and the Husimi distributions of the generated atomic states of one of the two moving atoms are explored. The results are shown that the atomic Husimi distribution and Wehrl entropy's mixedness are susceptible to an increase in the atom-photon and the atomic motion couplings. Therefore, the atomic phase space Husimi distribution coherence can be improved by increasing the atomic motion and nonlinear atom-photon couplings

    Generating non-locality correlation via 2-photon resonant interaction of dissipative two-qubit system with coherent field

    No full text
    In this paper, we introduce analytically the TC-model of two qubits interacting with a coherent cavity field via 2-photon process under the intrinsic dissipation effect. The interaction between the coherent cavity field and the two qubits, which are initially in an uncorrelated state, leads to generate non-locality qubit-qubit correlations. These correlations are investigated by using trace-norm measurement-induced nonlocality and Bures distance entanglement. It is found that the sudden appearance and sudden disappearance of the qubit-qubit entanglement depend not only on the intrinsic noise but also on the initial coherence intensity. The generated non-locality correlations and their stationary values may be controlled by the physical parameters of the intrinsic noise and the initial coherent field state
