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.

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.

Two new fractional entropy functions, first, based on extension of

Ubriaco and Shafee approach, and second, the generalization

through the use of concept of expansion of linear fractional

distributed order derivative, is proposed. The first entropies are the

two-parametric functions. The second entropy is a linear

combination of the above functions. Then they have the same

properties as the Shannon entropy except additivity. For q1, q2 

(0,1], these entropies satisfy the third law of thermodynamics in

the Bento sense, and, for q1 ≤ 1 and q2 ≥ 1, the Lesche stability

criteria.

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.

A strengths, weaknesses, opportunities, and threats (SWOT) analysis has become a key tool used

by businesses for strategic planning. Scholars have conducted SWOT research for over six

decades. However, a collective understanding of SWOT analysis remains vague. This study

accessed, analyzed, and synthesized the SWOT literature, allowing for new theoretical

perspectives and frameworks to emerge. Using an integrative literature review, this study reviewed

SWOT studies historically, providing a greater understanding of the SWOT analysis in different

sectors and the different approaches used in SWOT studies. Furthermore, it fills the knowledge

gap in the strategic planning context and indicates meaningful implications for managers that could

help improve their strategic decisions.
