Atmospheric residue fluid catalytic cracking was selected as a probe reaction to test the catalytic performance of modified NaY zeolites and prepared NaY zeolites. Modified NaY zeolites have been synthesized by simple ion exchange methods. Three samples of modified zeolite Y have been obtained by replacing the sodium ions in the original sample with lanthanum and the weight percent added are 0.28, 0.53, and 1.02 respectively. The effects of addition of lanthanum to zeolite Y in different weight percent on the cracking catalysts were investigated using an experimental laboratory plant scale of fluidized bed reactor.

The experiments have been performed with weight hourly space velocity (WHSV) range of 6 to 24 h

The evolution in the field of Artificial Intelligent (AI) with its training algorithms make AI very important in different aspect of the life. The prediction problem of behavior of dynamical control system is one of the most important issue that the AI can be employed to solve it. In this paper, a Convolutional Multi-Spike Neural Network (CMSNN) is proposed as smart system to predict the response of nonlinear dynamical systems.

The CMSNN has the capability of training weights based on a proposed training algorithm. The simulation results demonstrated that the proposed

0.850µm-wavelength 1D Vertical Cavity Surface Emitting Laser (VCSELs have matured as a short-distance optical communication light source that has small threshold currents, high modulation band width, and multimode fibers. In this paper, the design, simulation and analysis of an 850 nm oxide-confined 1DVCSEL have been presented using the Laser MOD tool from R-Soft software. The structure is a cylindrical-shaped design consisting of top and bottom DBRs, a multi-quantum well (MQW) active region, and an oxide aperture for transverse current for optical confinement. The numerical investigation gives rise to the spatial mode profiles, modal gain, threshold current, output power and far-field angle in terms of cavity or oxide aperture

This study investigates radiative proton capture reactions in light nuclei such as [⁹B- ⁷Li, - ⁷Be], which are crucial in stellar nucleosynthesis and energy production. The Woods-Saxon potential model was employed to describe nuclear interactions, and the Schrödinger equation was solved to determine bound and continuum state wave functions accurately. Astrophysical S-factors and reaction cross-sections were calculated at low energies characteristic of stellar environments, accounting for nuclear resonance effects that significantly enhance reaction probabilities. Radiative proton capture reactions, of the form A(p,γ)B, are fundamental processes in nuclear astrophysics. They are the primary mechanism fo

Polymethyl methacrylate (PMMA) is widely used for denture bases but suffers from limited fracture resistance; high impact acrylic, enhanced with butadiene styrene rubber, improves strength. Lasers, particularly the Nd: YAG type, have been used to modify acrylic surfaces, mainly to enhance bonding with soft liners; however, little is known about the effect of Nd: YAG laser treatment on other properties like hardness and color, which are critical for clinical performance and esthetics. The study objective was to evaluate the effect of nanosecond pulsed Nd: YAG laser irradiation with two different hatch values on the hardness and color of high-impact acrylic denture base material. Fifty acrylic samples were made and divided into three group

A foreign judicial ruling is not executed outside the territory of the court of the country that issued it by enforcement of law, but its implementation requires the intervention of the judicial or administrative authority in the requested state in respect of the principle of independence and sovereignty of the country. The latter undertakes the task of bringing down the ruling to apply repetition that benefits from the ruling issued in his service, and countries differ in determining the procedures followed to implement the foreign judicial ruling as well as they differ in determining the authority responsible for implementing a foreign judicial ruling. In Iraq, the Iraqi Court of Cassation hesitated in its successive provisions to dete

The Bundle Theory, or Electronic Personhood Theory, in the context of artificial intelligence (AI), is a theory adopted by the European legislature under the Artificial Intelligence Act 2024. It represents a legal and philosophical approach aimed at treating intelligent entities (such as robots and advanced AI systems) as independent legal persons, bearing certain responsibilities or possessing certain rights. The theory suggests that legal personality is not a fixed entity, but rather a bundle of legal attributes (such as financial liability, the right to sue, and liability) that can be granted to entities as needed. This theory has been used to grant legal status to companies and legal entities. Consequently, a future-oriented perspect

   There is a growing imperative to extract oil not only through primary and secondary means but also via tertiary recovery methods to meet the escalating global energy demands. Consequently, Enhanced Oil Recovery (EOR) is slated to increase significance in the oil industry in the coming years. The amalgamation of low salinity water (LSW) with chemicals to augment oil recovery has gained substantial traction in recent years owing to its demonstrated effectiveness. In this study, a systematic investigation utilizing contact angle measurements to elucidate the underlying mechanisms was undertaken. The results reveal that the contact angle (CA) demonstrated the effectiveness of the combined fluid in altering the wettability from oil-wet t

This study was aimed to investigate the effects of adding different concentrations of yeast on some of rumen fluid traits and some blood characteristics in adult Awassi lambs. The study was conducted in the animal house at the College of Veterinary Medicine/University of Tikrit for the period from 15/7/2017 to 1/10/2017, using 16 Awassi lambs, aged (10 – 12 months), and an average weight of (36 kg)., The animals were divided into four groups, each one included four lambs. The first group was considered as control (T1), without the addition of bread yeast to their foods. The diets in the other groups, (T2), (T3) and (T4) contained the  yeast in the proportions of 3, 5 and 7 gm/ animal / days, respectively.

Space Time Trellis Code (STTC) is a technique that can be used to improve the performance of
the Orthogonal Frequency Division Multiplexing (OFDM) system over wireless channels by
providing both coding gain and diversity gain. STTC is combined from two codes, Trellis Code
Modulation (TCM) as an inner code and Space Time Block Code (STBC) as an outer code. TCM
which combines the choice of a modulation scheme with that of a convolutional code provides the
coding gain, and the other code provides the diversity gain. Simulation is done over flat fading and
frequency selective Rayleigh fading channel for Eight Phase Shift Keying (8-PSK) TCM. It found
that the best results are obtained for the case of two tra

The topics that I wrote about Anbar took care with one side, because most of what was mentioned specializes with the special geographical nature of the region and its elements, neglected many social, urban and religious aspects, for a fundamental reason that the researcher sees, which is that Anbar did not occupy a metropolis.The Abbasid Caliphate was for a very limited period of time and did not have a great historical dimension. This is what the researcher believed, because Anbar did not have a sufficient period of time to be the capital of the Caliphate for a long time, and the accompanying construction, and its situation is similar to cities and villages that were built according to the desire of their owners.

One of the most efficient anthracycline anti-cancer medications, doxorubicin, is used to treat lymphoid malignancies. Intercalation with deoxyribonucleic acid is a key component of its primary chemotherapeutic mode of action, which can ultimately lead to heart failure. Therefore, the objective of this study was to determine whether the ethanolic extract of Ammi majus had any cardioprotective effects against doxorubicin toxicity in mice. 48 mature Albino male mice were separated into six groups and distributed as follows: for 14 days, Group I: "negative control" received distilled water; Group II: mice received a single oral daily dose of 64 mg/kg of Ammi majus seeds extract; Group III: mice received a single oral daily dose of 1

2-Amino-5-aryl- 1,3-thiazole-4-carboxylic acid (A1-A3) were synthesized from the reaction of various aromatic aldehyde with dichloro acetic acid and thiourea. The synthesis of 2-[[(Saminosulfinim-idoyl)(aryl)methyl](benzoyl)amino]-5-aryl-1,3-thiazole-4-carboxylic acid (A22-A30) was perfomed starting from (A1-A3) by two steps using Schiff's base (A4-A12) prepared  from the reactant compounds (A1-A3) with different aromatic aldehyde. Finally two types of imide derivatives were obtained from reactant compounds (A1-A3) with malic anhydride (A31-A33) and phthalic anhydride (A34-A36) in the presence of glacial acetic acid. All proposed structures were supported by FT-IR and UV-Visible spectroscopic data.
