Second-order Born calculations are performed to investigate the triple differential cross sections of coplanar asymmetric laser-assisted （e, 2e） collisions for hydrogen and helium targets. The incident electron is considered to be dressed by the laser field in a nonperturbative manner by choosing the Volkov solutions in both the initial and final channels. Detailed calculations of the scattering amplitudes are performed using the Sturmian basis expansion. The state of the ejected electron is described by a Coulomb-Volkov wave function. Two geometries are investigated in which the laser polarization vector is either parallel to the incident momentum of the projectile or parallel to the momentum transfer. Our numerical results show that, in the low energy range, these two laser polarization orientations give the same shape and the same order of magnitude of laser-assisted ionization cross sections of helium and hydrogen targets.

This study was undertaken to investigate the tensile properties and hot tearing susceptibility of cast Al–Cu alloys containing excess Fe(up to 1.5 wt%)and Si(up to 2.5 wt%).According to the results,the optimum tensile properties and hot tearing resistance were achieved at Fe/Si mass ratio of 1,where theα-Fe phase was the dominant Fe *** the Fe/Si mass ratio above unity increased the amounts of detrimentalβ-Cu Fe platelets in the microstructure,deteriorating the tensile properties and hot tearing *** the mass ratio below unity increased the size and fraction of Si needles and micropores in the microstructure,also impairing the tensile properties and hot tearing *** investigation of hot-torn surfaces revealed that theβ-Cu Fe platelets disrupted the tear healing phenomenon by blocking interdendritic feeding channels,while theα-Fe intermetallics improved the hot tearing resistivity due to their compact morphology and high melting point.

In order to synthesize new polyamide（PA） 5 and copolyamides（Co PA） 7a-7d, a new-type of dicarboxylic acid containing triazine ring was successfully synthesized from 2,4-dichloro-6-methoxy-s-triazine 1 and 4-aminobenzoic acid. New polyamide 5 containing triazine moiety was prepared from 4,4＇-（6-methoxy-1,3,5-triazine-2,4-diyl）bis（azanediyl）dibenzoic acid 3 and 4,4′-diaminodiphenylether by direct polycondensation reaction. Then new series thermally stable copolyamides 7a-7d with high solubility in common organic solvents were synthesized from the direct polycondensation reaction of diacid 3 as a first monomer, aliphatic-aromatic diacids 6a-6d as second diacids and 4,4′-diaminodiphenylether. All of the above polymers were fully characterized by 1H-NMR and FTIR spectroscopy, elemental analysis（CHN）, inherent viscosity, solubility tests, gel permeation chromatography（GPC）, differential scanning calorimetry（DSC） and thermogravimetric analysis（TGA）. The resulted Co PAs 7a-7d have shown good inherent viscosities, solubility and thermal properties.

Oxidative stress has been implicated in a number of human regeneration and disease processes including atherosclerosis, pulmonary fibrosis, cancer, and different neurodegenerative *** aim of this study was to evaluate the protective effects of Lactobacillus delbrueckii subsp. lactis DSM 20076 (LL-DSM) and Pediococcus acidilactici NNRL B-5627 (PA-NNRL) against the hepatic-and nephro-toxicity of fumonisin B1 (FB1) in FB1-treated rats for an experimental period of 4-weeks. Eighty mature male Sprague-Dawley rats were divided to 12 groups: 1 untreated group;3 groups fed by a FB1-contaminated diet (50, 100 and 200 mg FB1/kg diet,respectively);1 group fed orally by LL-DSM(1 ml/d);1 group fed orally by PA-NNRL (1 ml/d);3 groups co-administered by FB1-contaminated diet and LL-DSM (1 ml/d), and 3 groups coadministered by FB1-contaminated diet and PA-NNRL(1 ml/d). Malonaldehyde (MDA) nitric oxide, glutathione content, SOD activity, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. DPA assay was used to assess apoptosis in liver and kidney *** animals fed with FB1-contaminated diet showed a significant increase in oxidative stress markers and DNA fragmentation accompanied with significant decrease in GSH content, SOD activity, and TAC in liver and kidney tissues, especially at highdosage of FB1 (T200). Probiotics antioxidant strains (LL-DSM and PA-NNRL) relatively succeeded to restore almost all parameters investigated as well as to reduce DNA fragmentation in liver and kidney tissues. As a conclusion, probiotics may induce its protective role via increasing the antioxidant capacity, inhibition of lipid peroxidation, scavenging of free radicals and decreasing DNA lesions in liver and kidney of experimental animals tested.

Structural safety of building particularly that are intended for exposure to strong earthquake loads are designed and equipped with high technologies of control to ensure as possible as its protection against this brutal load. One of these technologies used in the protection of structures is the semi-active control using a Magneto Rheological Damper device. But this device need an adequate controller with a robust algorithm of current or tension adjustment to operate which is further discussed in the following of this paper. In this study, a neural network controller is proposed to control the MR damper to eliminate vibrations of 3-story scaled structure exposed to Tohoku 2011 and Boumerdes 2003 earthquakes. The proposed controller is derived from a linear quadratic controller designed to control an MR damper installed in the first floor of the structure. Equipped with a feedback law the proposed control is coupled to a clipped optimal algorithm to adapt the current tension required to the MR damper adjustment. To evaluate the performance control of the proposed design controller, two numerical simulations of the controlled structure and uncontrolled structure are illustrated and compared.
