The role of pH on removal of metal contaminated solution was investigated by adding gradually drops of NaOH to lead solutions, the increase of the pH was observed and concentration of lead solution was measured by using ICP. The activated pulverised fly ash (PFA) was used as stabilizing material. The leaching behaviour of lead was investigated using 5 grams of the soil thoroughly mixed with 0.1g of the stabilising material in a polypropylene container to which 50ml of either deionised water; the mixture was shaken on a flat bed shaker for 2h, and then filtered using a What man No 542 filter paper. The lead concentration in the filtrate was determined by inductively coupled plasma-atomic emission spectrometry (ICP). The effect of adding PFA was a reduction in Pb released to an undetectable level at higher pH levels. Results from the analysis of X-ray diffraction on the soil samples retained on the filter paper showed the formation of lead sulphate and lead carbonate.

This research highlights foreign, specialized and suitable regulations for the Lebanese petroleum industry and advises to apply strict punishments that force companies to consider environmental issues.

Corrosion of reinforcing steel is the one of the main causes of deterioration in reinforced concrete structure. During the initial stage of corrosion, the steel volume increases. This creates tensile stresses in the concrete, which can eventually lead to cracking, delamination, and spalling. This potential risk of corrosion in a structure is quite unpredictable. Therefore, this paper examines the influence of accelerated corrosion on the bond between concrete and the coated and uncoated steel bars. The bar coating consisted of epoxy rich in zinc. Six concrete mixes were prepared. Three mixes had cement contents of 300, 400 and 500 Kg/m3 and a water cement ratio of 0.4. In the rest of the mixes, cement was replaced with 10% silica fume and the water to binder ratio was 0.5. The reinforcing bars were placed inside concrete cylinders. After curing for 3 days, the specimens were immersed in a 5% NaCl solution for 7 days while a DC current of 5V flowed through them using a portable power supply. Different tests were conducted such as the accelerated corrosion test (ACT), the pull-out tests, compressive strength, and weight loss. The results show that coating the steel bars while lowering the water cement ratio with the addition of silica fume, reduces the effects of corrosion in reinforced concrete specimens

The misuse of antibiotics followed by improved fitness of resistant strains of infectious microorganisms hindered the efficacy of many known antimicrobial agents, and fueled research for the discovery of novel remedies. The current study aims at assessing the antimicrobial activity and understanding the mechanism of action of Rubus canescens DC. growing wild in Lebanon, as well as qualitatively determining its phytochemical profile. The antibacterial activity, MIC, and MBC of the extracts were evaluated by two-fold dilution. Time-kill curves were plotted to assess the bactericidal activity of the R. canescens DC. extracts against the growth of microorganisms, and TEM images were collected to confirm such effect. Overall, the extracts exhibited good antibacterial activity against MRSA and E. coli but not against S. pneumoniae and K. pneumoniae as determined by measuring the inhibition zones in plate-diffusion assays. TEM images of treated microorganisms revealed that the R. canescens DC. extracts induced irreversible deformations and damage to the cell membranes of the microorganisms leading to the leakage of cytoplasmic components and eventual cell death. Analysis of Time-Kill curves indicated that the extracts induced 100% killing of the test microorganisms within 10-18 h at the respective MBC. Finally, qualitative phytochemical analysis was conducted to decipher the active ingredients in the plant extracts.The current study reports the first data on the antimicrobial activity of different parts of R. canescens DC. Such promising data opens new avenues for broader assessment of the pharmacological profile of the scarcely investigated R. canescens DC.

Dynamic soil-structure interaction (SSI) is one of the main subjects that has attracted the attention of researchers in the recent decades. Numerous studies were interested in examining the seismic response of buildings supported on pile footings while including SSI. Most of these studies were simulating the problem by two dimensional models in the plane strain to overcome the usual difficulties encountered in 3D models. Commonly, piles were represented by plate elements of infinite length, disregarding the spacing between piles, and thus overestimating its stiffness. Recently, Plaxis – a finite element softwarehas implemented a new feature known as “the embedded pile row”. Although this latter models the pile as a 2D structural element, it allows the definition of an out-of-plane spacing where the soil can flow around the piles upon keeping a continuous mesh. Many researchers have studied the reliability of the embedded row element and verified its validity. The objective of this paper is to define the limitations of employing the plate feature in soilstructure pile interaction analysis. This is achieved by comparing the behavior of the structure and the pile foundation using the plate feature to that of the embedded pile row. In this scope, a series of 2D finite element models consisting of multistory buildings supported on pile footings are generated while varying the soil type, the earthquake frequency content, as well as the out-of-plane piles' spacing. This paper demonstrated that the building response with piles modeled as plate elements is just adequate when the surrounding soil is dense. Yet, regarding the pile response, the plate feature is unable to capture the real behavior for all soil types. Keywords—Plaxis 2D; Embedded Pile Row; Plate Element; SSI; Dynamic Response

Abstract No-Reference image quality assessment for face images is of high interest since it can be required for biometric systems such as biometric passport applications to increase system performance. This can be achieved by controlling the quality of biometric sample images during enrollment. This paper proposes a novel no-reference image quality assessment method that extracts several image features and uses data mining techniques for detecting the pose variation problem in facial images. Using subsets from three public 2D face databases PUT, ENSIB, and AR, the experimental results recorded a promising accuracy of 97.06% when using the RandomForest Classifier, which outperforms other classifiers

A series of high-temperature superconducting samples of type Cu0.5Tl0.5Ba2Ca2Cu3O10-δ, (Cu0.5Tl0.5)-1223, added with nano-Fe2O3 (0.01.0 wt. %) was prepared by a solid-state reaction technique via short time preparation procedure and under ambient pressure. The prepared samples were characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) for phase analysis and microstructure examination. The volume fraction results indicated that nano-Fe2O3 addition was significant in enhancing the formation rate of the (Cu0.5Tl0.5)-1223 phase, especially for x ≤ 0.2 wt. % samples. The electrical resistivity of the prepared samples was measured by the conventional four-probe technique from room temperature down to the zero superconducting transition temperature (T0). An increase in the superconducting temperature, Tc, is observed up to x = 0.2 wt. %, followed by a systematic decrease with increasing nano-Fe2O3 addition. The dielectric constants (ε' and ε''), dissipation factor (tan Δ) and real ac conductivity (σ'ac) were investigated as a function of temperature (113293 K) and frequency (102106 Hz). The results clarified that all these dielectric parameters show a strong dispersion with temperatures at low and moderate frequency ranges. Moreover, they are strongly dependent on nano-Fe2O3 addition. Furthermore, the high content of nanoFe2O3 addition (x = 1.0 wt. %) enhanced ε' and reduced tan D of (Cu0.5Tl0.5)-1223 phase, which is a desirable demand for practical applications.
