Abstract:
Background: The presence of anthraquinone (Disperse blue 64) and azodyes (Acid yellow 17) in a waterbody are considered among the most dangerous pollutants.

Methods: In this study, two different isolated microbes, bacterium and fungus, were individually and as a co-culture applied for the degradation of Disperse Blue 64 (DB 64) and Acid Yellow 17 (AY 17) dyes. The isolates were genetically identified based upon 16S (for bacteria) and ITS/5.8S (for fungus) rRNA genes sequences as Pseudomoans aeruginosa and Aspergillus flavus, respectively.
Results: The fungal/bacterial consortium exhibited a higher percentage of dyes degradation than the individual strains, even at a high concentration of 300 mg/L. Azoreductase could be identified as the main catabolic enzyme and the consortium could induce azoreductase enzyme in the presence of both dyes. However, the specific substrate which achieved the highest azoreductase specific activity was Methyl red (MR) (3.5 U/mg protein). The tentatively proposed metabolites that were detected by HPLC/MS suggested that the reduction process catalyzed the degradation of dyes. The metabolites produced by the action consortium on two dyes were safe on Vicia faba and Triticum vulgaris germination and health of seedlings. Toxicity of the dyes and their degradation products on the plant was different according to the type and chemistry of these compounds as well as the type of irrigated seeds.
Conclusion: We submit that the effective microbial degradation of DB64 and AY17 dyes will lead to safer metabolic products.

The Fock-Tani representation is a field theory formalism app
ropriated for the simultaneous treatment of composite particles and their constituents. The 3P0 model is a typical decay model which considers only OZI-allowed strong decays. The model considers a quark-antiquark pair created with the vacuum quantum numbers in the presence of the initial state meson. It is described as the non-relativistic limit of the pair creation Hamiltonian.
Applying the Fock-Tani transformation to the microscopic H amiltonian of the pair creation produces the characteristic expansion in powers of the wave function, where the 3P0 model is the lowest order in the expansion. The corrected 3P0 model (C3P0) is obtained from higher orders in the expansion, by the introduction of the bound state kernel ∆, called the bound state correction. The goal of this work is to study the aplication of the 3P0 model and C3P0 model in detail for the
J/Ψ mesons, where we consider that they are formed by mixing c1(u ̄u+d ̄d) +c2s ̄s+c3c ̄c. To consider J/Ψ given by mixtures comes from studies that attempt to solve the puzzle. We find the decay amplitudes and decay rates J/Ψ.

ABSTRACT
Through the introduced work a viable numerical scheme has been developed, using Numerov’s method, to study the energy spectra of mesons and hadronic interactions. Upon the implementation of the non-relativistic quark model and the Quantum Chromodynamics theory elements which describe the phenomenological interactions between the charm–anticharm quarks via two proposed potentials, our model accurately predicts the mass spectra of charmed quarkonium as an example of mesonic systems. It was found that our results agree well with the experimentalcharmonium masses that were published via the Particle Data Group (PDG). The proposed model has been tested for numerical instabilities and found that it works well for both proposed
potentials. Although this model is suited to study the dynamics of charmonium interactions,we found that the results for one of the potentials are in better agreement with the published data. In addition, we predicted the mass spectrum of new charmed multiplets using the same previously mentioned potentials.

ABSTRACT To calculate the complete fusion cross section over all partial waves, as a function of the excitation energy, the maximum values of angular momentum 1max represents the upper limit of that summation . An effective definition for that limit has been checked . Also a comparison with the fusion and critical limits ,1fus and 1cr respectively, has been displayed . The effect of the nuclear part of the barrier height and the approximation technique have been checked to approach the best fit of the measured fusion excitation functions .

Abstract: In order to improve the sensitivity and to reduce the working temperature of the CH4
gas sensor, a novel 1D nanostructure of CuO-doped In2O3 was synthesized by the co-evaporation
of Cu and In granules. The samples were prepared with changing the weight ratio between Cu
and In. Morphology, structure, and gas sensing properties of the prepared films were characterized.
The planned operating temperatures for the fabricated sensors are 50–200 ◦C, where the ability
to detect CH4 at low temperatures is rarely reported. For low Cu content, the fabricated sensors
based on CuO-doped In2O3 showed very good sensing performance at low operating temperatures.
The detection of CH4 at these low temperatures exhibits the potential of the present sensors compared
to the reported in the literature. The fabricated sensors showed also good reversibility toward the
CH4 gas. However, the sensor fabricated of CuO-mixed In2O3 with a ratio of 1:1 did not show any
response toward CH4. In other words, the mixed-phase of p- and n-type of CuO and In2O3 materials
with a ratio of 1:1 is not recommended for fabricating sensors for reducing gas, such as CH4. The gas
sensing mechanism was described in terms of the incorporation of Cu in the In2O3 matrix and the
formation of CuO and In2O3 phases.

Biological green synthesis of silver nanoparticles (AgNPs) from silver salts is a growing advanced approach to
avoid the requirement of costly instruments and involvement of hazardous chemicals as well. However,
increasing use of AgNPs raises potential toxicity level in the environment. In this investigation, leaf extract of
rosemary (Rosmarinus officinalis) used as a reducing and stabilizing agent for biosynthesis of AgNPs. The
biosynthesized AgNPs were authorized by UV-vis spectrophotometer and X-ray diffraction (XRD) analysis. The
shape and size of the biosynthesized AgNPs were studied using high resolution transmission electron microscope
(TEM). The toxicity of the biosynthesized silver nanoparticles on wheat and tomato plants was studied by
soaking wheat grains and tomato seeds in 100 mg/L AgNPs and follow its effect on seedling growth of wheat (at
10 days) and on vegetative growth of tomato and wheat plants (at 35 days). Some physiological parameters as
germination percentage of wheat seedling, length of seedling, dry weight, pigment fractions (chl.a, chl.b and
caroteinoids), soluble proteins, lipid peroxidation (MDA) and antioxidant enzymes (catalase and peroxidase) of
two plants were measured. AgNPs has a non-significant inhibitory effect on germination percentage of wheat,
dry weight and pigment fractions. The biosynthesized AgNPs has a noticeable stress effect on tomato plant as
reduced chlorophyll a and dry weight. Generally, AgNPs stimulate MDA accumulation in tomato and wheat
plants. There was a noticeable different effect of AgNPs on soluble proteins and antioxidant enzymes as catalase
and peroxidase among tomato and wheat plants.
