2017 and 2018 at Beni-Suef governorate. Samples from diseased cattle, previously SPPV vaccinated with SPPV, were inoculated in embryonated chicken eggs (ECE) using chorio-allantoic membrane (CAM) route. Histopathological examination of the inoculated CAMs showed large eosinophilic intracytoplasmic inclusion bodies characteristic for LSDV. Characteristic pock lesions were observed after the 1st passage and become clear after the third passage and become clearly observed 4 days post inoculation. For molecular identification, DNA was extracted from a pool of the infected CAMs. Two pairs of primers specific for LSDV including one flanking a 554 bp product of the G gene and second flanking 172 of the RP030 gene were used. In conclusion, LSDV infections have been detected and the virus has been isolated and identified by PCR from cattle previously vaccinated with SPPV vaccine during the summer of 2018

In this article, we propose a new method to construct many new exact solutions with

parameters for the generalized KdV–mKdV (GKdV–mKdV) equation with higher-

order nonlinear terms. The proposed method is a generalization of the well-known( G′

-expansion method in the case of the hyperbolic function solutions. Also, we

use a direct algebraic method based on the generalized Liénard equation to find other

diffrent new exact solutions of the above GKdV–mKdV equation. Soliton solutions,

periodic solutions, rational functions solutions, hyperbolic functions solutions and

symmetrical hyperbolic Lucas functions solutions are obtained. Comparing our new

results obtained in this article with the well-known results are given. The generalized( G′

virulence. Larval mortality was dose dependent for all EPN species. When using a dose of 100 infective juveniles (IJs) per larva, H. bacteriophora and S. carpocapsae caused 90%-100% mortality, whereas H. downesi and S. feltiae caused only 40%-60% mortality. Even when using 200 IJs/larva, H. megidis and S. kraussei caused a maximum of 30%-40% mortality. Some of the invasive EPNs were melanized, suggesting a strong humoral defense response by the Aedes larvae. The degree of melanization was quite variable; some EPNs were totally enveloped in a melanin sheath while others were partially coated with melanin. Melanization did not stop the EPN from multiplying and killing the Aedes larvae. IJs released from infected larvae would have the potential to infect healthy mosquito larvae. Also, both bacterial supernatant and bacterial cell suspension of Xenorhabdus nematophila caused >91% larval mortality after 48 h, whereas only the bacterial cell suspension of Photorhabdus laumondii was effective against the mosquito larvae. These data provides useful information on the potential use of EPNs and/or formulated bacterial cell suspensions in the control of the important urban and container-breeding mosquito, Ae. aegypti, and are a starting point for future simulated and actual field studies.

Nanoparticles thin films of the titanium dioxide (TiO₂) exhibit many interesting properties that can be exploited in a variety of applications such as such as a Photocatalysts, Dye-sensitized solar cell, Gas sensors, Electronic devices and an insulator (buffer layer) in the dielectric bolometer sensor, which are very important to investigate and study the properties of its current density. This review discusses the applications and syntheses of titanium dioxide (TiO2) and outlines methods of preparation that allow control over the size, morphology, surface treatment.

The purpose of this work is to investigate the batch removal of Pb2+ from aqueous solutions using marine dried brown seaweed S. baccularia. Seaweed was used as a low-cost adsorbent. The effects of pH, contact time, temperature, shaking speed and the concentration of the Pb2+ solution were examined in the biosorption process with S. baccularia. The results showed that when S. baccularia was used as the bioadsorbent, the optimum pH, Pb2+ concentration, equilibrium time, temperature, and shaking speed were 3, 20 ppm, 120 min, 30°C, and 120rpm. The equilibrium adsorption data are fitted to the Langmuir isotherm model. The separation factor (RL) in the experiment was less than one (<1), indicating that the adsorption of metal ions on Sargassum baccularia adsorbent is favorable. The calculated activation energy (Ea) implies that the adsorption of Pb (II) on brown seaweed is a physical adsorption. Thermodynamic results show that adsorption occurs spontaneously in nature.

The purpose of this study is to determine the suitability of system measurements on indoor radio wave propagation at (28–33GHz) which might be used by 5G communication.

This paper is the continuation of a research carried out by Alabish et.al, which depicts the scattering objects effects on a blocked indoor wireless 5G link by a human body using a simple approach. Some measurement were made on the scattering effects due to having an object close to the link in this case it is a human body. In this paper, more measurements were conducted at 32 GHz. The double knife-edge diffraction (DKED) model was used in order to foresee the attenuation due to human body. To test the prediction precision of the model, simulation was then compared with measurements. The obtained results indicate that the assumed simple models for the indoor links performed well.

This paper is concerned with studying the effects of human body blockage as well as surrounding objects scattering effects for an indoor 31 and 33 GHz link utilizing the Double Knife Edge Diffraction (DKED) model for diffraction effect on received signal.

Field experiment was conducted to evaluate the correlation relationship between the yield of two localized wheat genotypes (Triticum aestivum,) Acsad 901 and Salamboo and Olsen phosphorus soil test (0.5 M of NaHCO3 at pH 8.5) values. The experimental site was run at west sector of Libya. The experimental site pH was 8.4 and the texture is sandy The experiment consisted of three replicates and three phosphate fertilizer rates which equivalent, (0, 60, and 120) kg P2O5 ha-1 for both genotypes. The results of grain yield of the experiment were expressed by relative values (Relative Yield). The relative yield (RY) illustrated the relationship between soil test values and the grain yield clearly. Very close correlation relationship (r = 0.98 ) between relative yield of grain and the soil test values of Salamboo was found whereas Acsad genotypes was achieved less correlation( r =0.69) at 0 kg P2O5 ha-1 for both genotypes. The similarity between the two genotypes was very close (r = 0.99 ) for treatments that received high phosphate rate.

In this paper we introduce a new fractional generalization of the

Smith's formula for the classical generalization of the Drude

equation. The generalized Drude formula described was proposed

originally to account for the unusual behavior of the optical

properties of mercury and its amalgams, it can be used for liquid

tellurium and some quasicrystals.
