Authors: K. Hamadi Adeebah , A.Kheioon Imad
Published: July 2024

The control of liquid level in the oil and natural gas industry is a very important subject since it affects the shutdown of the sale and transport of these sensitive products. In the oil separator, because of the mixing of the accompanied water, oil and accompanied gas, therefore, the level of oil must not be exceed a such rang as well as not to be less than a proper level. For this reason, this work is focused in modeling a Simulink and mathematical model for multi-stage oil separator structure and applies the intelligent schemes in order to control the angles of most inlet and outlet valves at the same time. This technique will improve the behavior of the level response in terms of the rise time, maximum present overshoot, settling time and steady state error. Also, a comparison has been implemented between (fuzzy logic, Nonlinear Autoregressive-Moving Average (NARMA-L2)) against conventional control methods such as PID control. Faster response for most oil separator can be achieved as it appears from the simulation results. Also, multi input variable that affect the system outputs can be treated accurately by a proper rule base adjusting in fuzzy logic or adequate training data in the NARMA-L2. The effective factors of fuzzy logic and NARMA-L2 had been optimized and studied where the simulation results had demonstrated that there are special magnitudes for each new application

Published: July 2024

A simply supported beam is used to calculate the critical buckling load. A common beam sections with constant cross sectional area are used to analyze the results using ANSYS11 program which gives a good results as comparing with the theoretical equation. The critical buckling load depends on the shape and dimensions of beam section which has constant cross sectional area. It observed that the critical buckling load is higher with a wide range of width for thinner hollow rectangular-section than the thicker section and lower for ( I, T & L-sections). Changing the width or thickness for U & Z-sections gave a small effect on the critical buckling load. Increasing the thickness of hollow circle beam section gives a decreasing in the critical buckling load. The last beam section gives a higher critical buckling load as comparing with solid circle section of the same cross sectional area. The same phenomenon is found for hollow rectangular-section as comparing with the solid section.

Authors: Hamed Mahmoud Mohammed , Jaber Alkhakani Ali
Published: July 2024

Power generation by using concentrated solar thermal energy on liquid enclosures is one of the most promising renewable energy technologies. In this work, a developed liquid enclosure fitted with various number and configurations of horizontal metal rings have been analyzed, fabricated and tested. The influence of adding metal rings arrangement is investigated for its potential to enhance radial heat conduction to the center-line of the enclosure from the side-walls. Experiments were carried out for fluid in both static and dynamic modes of operation inside the enclosure that subjected to high heat flux.A developed two-dimensional CFD model to predict the transient flow and thermal fields within liquid enclosure subjected to heat flux has been developed and tested. The developed numerical model takes into consideration energy transport between the liquid inside enclosure and the solid material of the enclosure. The numerical simulations have been compared with experimental measurement. The computational code has been found in a good level of agreement with the experimental data except for liquid at the peak part of the enclosure. The results indicate that adding metal rings produce significant impact on the transient temperature difference inside enclosure during both static and dynamic modes. The six-ring model is found to be more effective for enhancing radial heat transfer than other three models that have been tested. The in-line arrangement is found to provide better thermal effect as compared to the staggered rings.Two new correlations for natural heat transfer inside liquid enclosures subjected to high heat flux have been formulated (one for no-ring model and the other for six-ring model). The natural Nusselt number is found to be around a constant value for Rayleigh number less than (5 x 108). The recommended use of metal rings inside liquid enclosures subjected to heat flux, and the predicted Nusselt number correlation, will add to local knowledge a significant mean to gain more heat in large scale concentrated solar power plants.

Authors: H. Al Aboodi Ali , F. Munshid Huda
Published: July 2024

A two-dimensional model was developed to simulate the unsteady state flow of groundwater in the upper part of Dibdibba sandy unconfined aquifer in Safwan-Zubair area, south of Iraq,in order to assess the hydraulic characteristics in this aquifer by the comparison of the observed head and calculated head, as well as the use of this model to predict the groundwater head in case of changing weather conditions. The suggested conceptual model, which is advocated to simulate the flow regime of aquifer, is fixed for one layer, i.e. the activity of the deeper aquifer is negligible. Seven cases were considered during sensitivity analysis. The results of sensitivity analysis showed that the increment of the initial values of hydraulic conductivity (K) and specific yield (Sy) more than 100% can lead to a noticeable increment in the level of groundwater.The unsteady state calibration results were evaluated by comparing the temporal variation in simulated heads with those of observed ones at thirteen observed wells.According to the calibration process, the hydraulic characteristics of the upper aquifer have been redistributed; the hydraulic conductivity in the study area was between (15-150) m/day, while the specific yield was between (0.125-0.45).

Impact of cutting types and commercial plant growth regulators on the propagation of red star begonia (Begonia rex-cultorum)
Authors: Latifah Zahrotul , Wurjani Widi , Sutini Sutini
Published: July 2024

Begonia is an ornamental plant known for its beautiful, variegated leaves. Propagation of this plant via vegetative means, particularly using leaves, often encounters challenges such as drying, rotting, and mortality of cuttings, necessitating the use of plant growth regulators (PGRs) to support their development. This study aims to determine the optimal combination of cutting type and commercial PGR concentration for the growth of red star begonia leaf cuttings. A factorial completely randomized design (CRD) was employed with two factors: cutting type (whole leaves and leaf slices) and PGR concentration (250 ppm, 300 ppm, 350 ppm, and 400 ppm), each replicated three times. The results indicated that the best combination for leaf number, root length, primary root number, and survival rate was whole leaves with a PGR concentration of 400 ppm. For the earliest sprout emergence, the best treatment was a PGR concentration of 350 ppm. These findings can enhance the efficiency of vegetative propagation of red star begonia, reduce propagation failure rates, and provide practical guidance for growers and ornamental plant enthusiasts in selecting optimal methods and PGR concentrations.

Uranium–containing structural units are complexes [UO2(C2O4)F3]3ˉ (for I and II), [UO2(C2O4)2F]3- (III) and [UO2(C2O4)F]- (IV), accordingly with crystal chemical formulas А(В01)M13, А(В01)2M1 and А(Q02)M1, where A = UO22+, B01 or Q02 = C2O42-, and M1 = F- . In all compounds U(VI) atoms implement pentagonal-bipyramidal coordination, at that in I—III uranyl complexes have single–core structure, and in IV crystals–chain structure which is similar for the well — known for [UO2(C2O4)(H2O)] · 2H2O. The obtained results suggest that a sharp increase in the solubility of uranyl oxalate trihydrate in aqueous solutions with the addition of fluorides is due to the well-known effect of structural depolymerization of coordination polymers of d- or f-metals in the presence of fluoride ions. Semi-empirical calculation and comparison of calculated and experimental oscillation frequencies in IR spectra II and IV are carried out.

National trends in the use of aquatic bioresources
Authors: Makoedov A. N. , Matishov G. G. , Ponomareva E. N.
Published: July 2024

The article examines the domestic trends in the use of aquatic biological resources for more than a century. Until the early 1950s, inland waters, primarily the Caspian and Azov Seas, played a key role. Total catch volumes did not exceed 2 million tons. Anthropogenic impact has led to global negative changes in the ecosystems of the south seas of our country. The fishery importance of inland reservoirs has significantly decreased. The active development of oceanic fishing in the 1960s and 1980s made it possible to increase the volume of extraction of aquatic biological resources to 10−11 million tons. Starting in 2018 Access to the use of aquatic biological resources largely depends on the involvement of domestic industrial companies in the construction of new ships at Russian shipyards. The proven reserves of even traditionally mined hydrobionts make it possible to fully ensure the fishing capacities of all vessels currently under construction and under design. The contribution of commercial fish farming to the total production of domestic fish products in the foreseeable future, apparently, will not exceed 10%.

Reliable assessments of the state of modern energy show the relevance of scientific and technical developments aimed at solving its problems. In this regard, the use of resonance phenomena in electrical circuits with active-reactive elements acquires particular significance. Their various combinations open up exceptional opportunities for creating fundamentally new efficient energy sources. This article discusses a resonant active electrical power amplifier containing a sequence of several electrically connected active-reactive circuits, which, depending on the purpose, are excited in the voltage resonance or current resonance mode. An equivalent circuit is proposed for the proposed resonant amplifier of active electrical power, represented by two blocks, each of which consists of a sequence of inductively coupled active-reactive circuits excited at the same frequency. Calculations are presented showing the theoretical justification for the performance of the proposed scheme. The analysis of ongoing electromagnetic processes was carried out using well-known methods of the theory of electrical circuits without involving any hypotheses about the physics of resonance phenomena. It is shown that in the proposed amplifier circuit, the first block amplifies the reactive power of the harmonic signal with a high conversion coefficient, the second, with a slight gain, converts the reactive power of the harmonic signal into active power. The results of calculations are presented, illustrating the functional dependence of the integral gain on the main characteristics of the output resonant circuit. Numerical estimates of the main characteristics of the proposed circuit showed that with an appropriate choice of its parameters, high values of the output characteristics are possible, so the gain can reach a value of ~ 48. The significance of the results obtained for practice lies in their use for formulating recommendations for the creation of real efficient sources of electrical energy, the principle whose actions are based on the use of natural resonance phenomena.

In the domain of cyber security, the efficacy of Intrusion Detection Systems (IDS) is critical for the proactive identification and mitigation of cyber threats. This research delineates a novel paradigm for enhancing IDS accuracy through the integration of advanced Artificial Intelligence (AI) methodologies, thereby setting a new benchmark in network security defense mechanisms. Utilizing a synergistic approach that combines both descriptive and inferential statistical analyses, this study introduces an expert system endowed with the capability to detect network intrusions with an unparalleled accuracy rate of 99.98%. By incorporating Extreme Gradient Boosting (XGBoost) for the classification of predefined attack vectors and a Variational Autoencoder (VAE) for anomaly detection, the research extends the boundaries of current cyber threat detection frameworks. These methodologies not only enhance the precision of threat categorization but also introduce a mechanism for the system to adapt to novel, previously unidentified cyber threats through real-time learning and adaptation to emerging data patterns. Critically, the expert system is engineered to facilitate high-speed data processing and supports online learning, making it optimally suited for application in high-traffic network environments. The scientific novelty of this research is encapsulated in the formulation of advanced AI-driven models for the dual purposes of traffic anomaly detection and the classification of cyber-attack types based on distinctive behavioral characteristics. These models are meticulously designed to evolve, learning from new data in real time, thereby continuously enhancing the system's efficacy. In practical terms, the system provides a robust solution for the protection of digital ecosystems against intrusions, enabling the automatic filtration of malicious network traffic. Beyond its immediate applicability, the study contributes to the field of cyber security by laying down a foundational framework for the future exploration of AI-based security solutions. It invites further scientific inquiry into the development of adaptive, intelligent IDS mechanisms, potentially revolutionizing the approach to cyber defense strategies.

In this study, the primary objective is to investigate the impact of various particles on the hydrophobic characteristics of a coating. The experimental approach involves employing a conventional chemical precipitation method to fabricate ZnO particles. Subsequently, composite materials of SiO2-ZnO are synthesized based on these ZnO particles. The coating is formulated using styrene-butyl methacrylate as the principal raw material. Different particles, namely TiO2, SiO2, ZnO, and ZnO-SiO2, are individually added to the coating, allowing for the exploration of the influence of distinct mass ratios on the resulting hydrophobic angle.
The findings of this investigation reveal a notable trend in the contact angles of the four materials as the mass ratio varies. Initially, the contact angles experience an increase, followed by a subsequent decrease. Remarkably, when the mass ratio of ZnO-SiO2 is set at 60%, the contact angle achieves an impressive 152.5°, meeting the criteria for superhydrophobicity. In comparison to a pure acrylate polymer coating, the incorporation of particles induces agglomeration on the coating's surface. This agglomeration can be conceptualized as clustered particles, contributing to heightened surface roughness in the coating and consequently enhancing its hydrophobic properties.
The observed variations in contact angles underscore the nuanced interplay between mass ratios and hydrophobicity, shedding light on the optimization possibilities for achieving superhydrophobic coatings. The study suggests that manipulating the composition of particles within the coating formulation can be a viable strategy for tailoring hydrophobic properties. Furthermore, the surface modifications induced by particle incorporation provide valuable insights into the underlying mechanisms governing the hydrophobic behavior. This research contributes to the broader understanding of materials science and surface engineering, offering potential applications in areas where superhydrophobic coatings are desirable, such as anti-fouling surfaces, self-cleaning materials, and advanced protective coatings. The exploration of such multifaceted relationships between particle composition and hydrophobicity holds promise for the development of innovative materials with tailored surface properties.

This study aims to uncover hidden dependencies between streams of solar particles emanating from the Sun and flood events caused by precipitation in the UK. The uniqueness of this work lies in applying solar activity data as input parameters for machine learning and correlating them with real data on precipitation intensity and floods in the UK, which serve as output data. The analysis covered 20 significant floods from October 2001 to December 2019. The analysis was performed on a daily basis, taking into account the time shift between solar emissions and their impact on terrestrial weather conditions, which ranged from 0 to 9 days. The study employs correlation analysis to determine the degree of interrelation between time series of solar activity and floods, laying the foundation for a deeper understanding of possible cause-and-effect relationships. Subsequently, using predictive modeling methods, including decision tree algorithms and ensemble classification models, the potential connection between changes in solar activity and terrestrial floods was explored. An ensemble of models was created using the hard voting method, which takes into account various indicators such as proton density, differential proton flux, and ion temperature, with a time shift of up to 9 days. The analysis showed that these key parameters could effectively predict the occurrence of floods with up to 92% accuracy for the specified period. The results underscore the importance of integrating space weather and solar activity into the models for predicting terrestrial weather conditions, particularly in the context of floods in England. This not only allows for a better understanding of the causes of natural disasters but also enhances the effectiveness of emergency planning and reduces potential damages from them. Thus, this work makes a significant contribution to the field of space weather research and its impact on Earth, particularly in the areas of hydrometeorology and flood risk management.
