THESE days green advancements of phytohormones have a critical place in industrial food process displace the chemical manufacturing which causes genuine dangers by gathered in the environment, from these hormones; gibberellin has an industrial significance as it’s a plant development controller hormone. Fungi produced several important substances with biological impact; from these substance plant hormones production involves great interest in agriculture. From different fungal isolates tested for gibberellins production, Fusarium oxysporum represented as a hopefulfungus for microbial gibberellin generation conducted 268.9±6.27 mg/l gibberellic acid with productivity rate 38.42 mg/l/day with succeeded capacity to apply in the field. In vivo application of microbial gibberellic acid occurred in pot experiment on Zea mays (L.) plants under water salinity stress. Synergetic development in maize plants exhibited with expanding microbial gibberellin concentrations until 150 ppm under water salinity stress and then no huge diverse was cleared.Increasing in plant weight and height observed in compared to the non-treated plants.

We study the spontaneous emission in high-gain free-electron lasers operating in the quantum regime
and its detrimental effect on coherent emission. A quantum model describing the coherent and spontaneous
emission in free electron lasers has been recently proposed and investigated [G. R. M. Robb
and R. Bonifacio, Phys. Plasmas 19, 073101 (2012)]. The model is based on a Wigner distribution
describing the electron beam dynamics, coupled to Maxwell equations for the emitted radiation field.
Here, we rephrase the model in a more rigorous way, considering a discrete Wigner distribution
defined for a periodic space coordinate for which the electron momentum is discrete. From its numerical
solution, we find good agreement with the approximate continuous model. In the quantum
regime of the free-electron laser, we obtain a simple density matrix equation for two momentum
states, where the role of the spontaneous emission has a clear interpretation in terms of coherence
decay and population transfer.

The density matrix in the Lindblad form is used to describe the behavior of the Free-Electron Laser (FEL) operating in a quantum regime. The detrimental effects
of the spontaneous emission on coherent FEL operation are taken into account. It is shown that the density matrix formalism provides a simple method to describe
the dynamics of electrons and radiation field in the quantum FEL process. In this work, further insights on the key dynamic parameters (e.g., electron populations,
bunching factor, radiation power) are presented. We also derive a simple differential equation that describes the evolution of the radiated power in the linear regime.
It is confirmed that the essential results of this work agree with those predicted by a discrete Wigner approach at practical conditions for efficient operation of
quantum FELs.

Securing medical images are a very essential process in medical image authentication. Medical
image watermarking is a very popular tool to achieve this goal. In this paper, an extremely fast, highly
accurate, and robust algorithm is proposed for watermarking both gray-level and color medical images.
In the proposed method, a scrambled binary watermark is embedded in the host medical image. Simplified
exact kernels are used to compute the moments of the polar complex exponential transform (PCET) for
the host gray-level images and the moments of the quaternion PCET for the host color images without
approximation errors. The stability of the computed moments enables us to use higher order moments in
a perfect reconstruction of the watermarked medical images. The accurate moment invariant to rotation,
scaling, and translation ensures the robustness of the proposed watermarking algorithm against geometric
attacks. Performed experiments clearly show very high visual imperceptibility and robustness to different
levels of geometric distortions and common signal processing attacks. The implementation of parallel
multi-core CPU and GPU result in a tremendous reduction of the overall watermarking times. For a color
image of size 256 × 256, the watermarking time is accelerated by 20× and 11× using a GPU and a CPU
with 16 cores, respectively.

With an intention to synergize the antimicrobial
activity of 1,3-diphenyl pyrazole and chromene derivatives,
20 hybrid compounds were synthesized and evaluated
for their antimicrobial activity. Structures of the newly
synthesized compounds were established by elemental
analysis and spectral data. All compounds were evaluated
for their antimicrobial activity against Gram positive and
Gram negative bacteria and antifungal activity by a well
diffusion method. Compounds 8, 10, 16 and 21 show reasonable
antibacterial and antifungal activity.

Anodization of some valve metals such as titanium (Ti), leads to the self-organized nanostructured. In
this work we present a systematic study of the formation, characterization, and refractive index of
titanium dioxide (TiO2) nanotubes. The anodizing of Ti foil was performed in ethanol-H2O
electrolyte (50%) mixture containing 0.3 wt% HFat different voltages and durations. It was found that
the current density, measured during preparing the samples, is controlled by the variation of the
anodizing voltage. In addition, increasing the applied voltage used in the anodizing process resulted in
an increase of the calculated refractive index of nanostructured samples. The results also revealed that
the nanotube diameter, wall thickness, center-to-center nano-tube, and porosity, refractive index are
affected by changing the anodizing parameters.
