British press coverage of international sports events hosted by Saudi Arabia: content analysis study in light of country concept model
Authors: Almahraj Yazeed Abdullah 
Published: October 2023

AbstractThis paper examines the British press coverage of international sports events hosted by Saudi Arabia. The study provides an analytic perspective by employing the model of the country concept and the covered by the British press of the international sports events in Saudi Arabia. This study fills the gap in the literature on the British press coverage of sports events hosted by Saudi Arabia in light of the country concept model. For this research, the study employed content analysis to collect data from the two British newspapers, The Sun and the Daily Mail coverage. The paper has several contributions to knowledge. Firstly, it brings an understanding of the role of the country concept model in explaining the reputation and image of a country. Using Fullerton’s model, the paper has found that by employing a soft power package that includes hosting international sports events, Saudi Arabia’s country image has changed. Secondly, the research found that the most coverage of events in Saudi Arabia was still negative. However, this negative coverage has decreased over the past few years, while neutral and positive coverage has increased. Finally, the research has contributed to the literature by finding out that the coverage of Saudi Arabia was characterised by a large number of negative articles, as opposed to more neutral or positive reporting. This finding confirms the country concept model, which states that some elements, like foreign and social media, cannot be controlled.

Modeling environments that are not in local thermal equilibrium, such as protoplanetary disks or planetary atmospheres, with molecular spectroscopic data from space telescopes requires knowledge of the rate coefficients of rovibrationally inelastic molecular collisions. Here, we present such rate coefficients in a temperature range from 10 to 500 K for collisions of CO2 with He atoms in which CO2 is (de)excited in the bend mode. They are obtained from numerically exact coupled-channel (CC) calculations as well as from calculations with the less demanding coupled-states approximation (CSA) and the vibrational close-coupling rotational infinite-order sudden (VCC-IOS) method. All of the calculations are based on a newly calculated accurate ab initio four-dimensional CO2–He potential surface including the CO2 bend (ν2) mode. We find that the rovibrationally inelastic collision cross sections and rate coefficients from the CSA and VCC-IOS calculations agree to within 50% with the CC results at the rotational state-to-state level, except for the smaller ones and in the low energy resonance region, and to within 20% for the overall vibrational quenching rates except for temperatures below 50 K where resonances provide a substantial contribution. Our CC quenching rates agree with the most recent experimental data within the error bars. We also compared our results with data from Clary et al. calculated in the 1980s with the CSA [A. J. Banks and D. C. Clary, J. Chem. Phys. 86, 802 (1987)] and VCC-IOS [D. C. Clary, J. Chem. Phys. 78, 4915 (1983)] methods and a simple atom-atom model potential based on ab initio Hartree–Fock calculations and found that their cross sections agree fairly well with ours for collision energies above 500 cm−1, but that the inclusion of long range attractive dispersion interactions is crucial to obtain reliable cross sections at lower energies and rate coefficients at lower temperatures.

Context Currently, since the use of antibiotics as growth promoters in animals has been banned worldwide, it is necessary to use other additives that indorse an adequate balance of the intestinal microbiota, so as to render better results in nutrient acquisition and health of poultry, yielding adequate growth and performance. Aim The study evaluated the effects of dietary supplementation with symbiotics during the grower phase, to replace bacitracin zinc. Methods The experiment included a total of 684 pullets of the Dekalb White strain, from 6 to 15 weeks of age, distributed in a completely randomised design, with five treatments, and eight replications of 18 birds each. The treatments were composed of two base diets, namely one of corn and soybean meal (reference diet, RD), and another of meat and bone meal (MBM), in addition to two more diets based on MBM, one with an addition of 0.05% of bacitracin zinc (Bac Zn), and the other with 0.1% of symbiotic provided to two groups, including one group that had already consumed the symbiotic since the first day of life (starter phase, Symb-S), and the other that started to consume at the beginning of the experiment (grower phase, Symb-G). Performance, blood variables, nutrient metabolisability, weights of organs of the immune and digestive system, and measurement of length (intestine and caecum) were determined. Data were compared using orthogonal contrast. Key results The birds fed with the RD diet presented a worse overall performance and coefficients of apparent metabolisability of dry matter (CAMDM) (6–10 weeks) than did those fed the MBM diet. Birds fed with the Bac Zn diet showed better bodyweight gain (6–15 weeks), coefficients of apparent metabolisability of gross energy (CAMGE) and CAMDM (6–10 weeks) than did those fed the MBM diet. Birds fed with symbiotic diets had better responses in blood biochemistry variables (alkaline phosphatase, total proteins) than did those fed the Bac Zn diet. Conclusion The use of symbiotics since the starter and grower phase can replace the use of Bac Zn, without affecting the biochemical and metabolic responses of the pullets. Implications Symbiotics improved utilisation of diet nutrients, maintenance of physiological homeostasis, and growth of pullets.
Improvement in operator safety for low- and middle-income countries: A user-friendly, consistent risk assessment and mitigation process

Abstract
Ensuring operator safety when handling and applying chemical pesticides is an important aspect of pesticide registration. A risk-based approach to assess if operators can safely apply a pesticide product is usually conducted in countries with a regulatory infrastructure to support the relatively complex process for risk assessment. However, most low- and middle-income countries (LMIC) have limited expertise and/or resources for conducting sophisticated operator risk assessments. The FAO Pesticide Registration Toolkit was developed to support regulators from countries with limited resources to conduct operator risk assessments for national/regional pesticide registration processes. The two operator exposure models referenced in the FAO toolkit for agricultural use, based primarily on studies conducted in Europe and the United States, focus more on mechanical-assisted spray equipment prevalent in those regions. The models for hand-held application technology are based on a rather limited dataset. The applicability of the models for scenarios prevalent in the country and complexity of the risk assessment process are the two key challenges LMIC countries face in using the models referenced in the toolkit.
A global initiative that builds on existing expertise and available studies is underway to develop a global database and operator exposure model for handheld application scenarios prevalent in most LMICs. The goal is to develop a user-friendly risk assessment and mitigation tool to be proposed for inclusion in the FAO toolkit. This article provides a brief overview of risk assessment and examines factors that contribute to the accuracy and consistency of exposure models and risk mitigation measures to ensure operator safety. It also proposes suggestions that can serve as the basis for a user-friendly risk assessment and risk mitigation tool based on a global database for handheld applications

Published: October 2023

Abstract
We evaluate a one-way, bidirectional, and cyclic quantum controlled teleportation with two controllers. We show that the controllers’ agreement mimics the OR logic gate, i.e., the teleportation succeeds with only one of the controllers’ cooperation, and it does not matter which one. This result is generalized to multi-way quantum controlled teleportation with N controllers. The proposed protocols are evaluated by considering a noisy environment in the form of phase-damping noise and amplitude-damping noise and the dependence of fidelity only on the decoherence rate and the initial state’s amplitude parameter were established. It is interesting to note that for the phase-damping noise case, there are states with perfect fidelity (and the entropy equal to zero) even in a noisy environment. We discuss the novelty of the proposed protocols and highlight that they can be useful if the information to be teleported needs an OR-logic-gate-like controllers’ agreement combination, which cannot be done with other existing protocols.
Thomson scattering: one rate to rule them all

Published: October 2023

AbstractThe enduring tension between local and distant measurements ofH0remains unresolved. It was recently pointed out that cosmic microwave background (CMB) and large-scale structure (LSS) observables are invariant under a uniform rescaling of the gravitational free-fall rates of all species present and the Thomson scattering rate between photons and electrons. We show that a unique variation of the fine-structure constantαand the electron massmecan leverage this scaling transformation to reconcile the CMB and LSS data with a broad spectrum of Hubble constant values, encompassing those inferred from local measurements. Importantly, this study demonstrates that the constraints on the variation of fundamental constants imposed by the specific recombination history are not as stringent as previously assumed. Our work highlights the critical role of the Thomson scattering rate in the existing Hubble tension and offers a distinct avenue of exploration for particle model builders.

Abstract
Today drilling wells is one of the biggest capital expenditures and is employed starting from exploration, delineation, initial wells for production, and fresh production incorporation when existing wells production have declined. The estimated cost for drilling new wells in Ayatsil field is around 25 MM$, which requires a high level of decision to achieve production goals without exceeding the budget assigned. Therefore, to make the right decision requires an integration of multidisciplinary group of specialists (geologists, geomechanics, reservoir, production and drilling engineers) from well design to execution phases.

Abstract
Tight gas reservoirs in Daqing Oilfield has the characteristics of deep burial, high temperature and high pressure, and the produced natural gas generally contains CO2. At present, the production casing and tubing of the tight gas reservoir are completed with 13Cr110 material, which has high cost, but the gas production is low, and it declines very fast, so the economic benefit is poor. In order to reduce cost and increase the efficiency, it is necessary to explore a new well completion method in tight gas reservoir. We study the corrosion law of different materials through laboratory experiments, and finally determine that the production casing adopts the assembly method, material of production tubing next to the production packer is 13Cr, other parts are ordinary carbon steel. The tubing and downhole tools are made of carbon steel, and the casing and tubing annulus are injected with annulus protection fluid for corrosion protection. With the comprehensive analysis, this completion method can meet the requirements of gas well corrosion prevention and production. After 20 years of development, the well construction cost of a single well has been reduced by 79% to 7.553 million RMB. The effective implementation of this design can provide reference for the subsequent development of tight gas reservoir in Daqing Oilfield.

Abstract
Recently, plenty of offshore platforms have faced decommissioning. Offshore steel structures covered with rust, mud, and barnacles require suitable cutting methods for their removal. The non-transferred plasma arc is highly efficient in cutting both conductive and non-conductive materials and is expected to play an important role in offshore demolition operations. This work aims to investigate the underwater penetration process of non-transferred plasma arcs on steel structures covered with non-conductive substances. The workpiece consisted of a 5 mm cement layer and a 10 mm steel plate, whose removal mass and hole morphology were recorded at several moments. It was found that the hole of the cement layer was larger than that of the steel plate, while the mass removal rate of the steel plate was much higher than that of the cement layer. The hole in the cement layer gradually changes from an inverted cone to a drum, and the hole in the steel plate is always an inverted cone. A combined heat source model with time variation is proposed based on the experimental results, and a 2D axisymmetric simulation model is developed. The error between the simulated and experimental hole dimensions was within 3.1%, proving that the proposed heat source model can reflect the heat process of the workpiece well.

Published: October 2023

Abstract
Seawater flooding is popular for carbonate reservoirs in offshore oilfields and seawater is sometimes the unique choice of injection water source due to the lack of surface water supply. Seawater is injected into reservoirs to maintain reservoir pressure after water treatment for technically and economically effective field development. Uneven injection and production in B oilfield caused unbalance of pressure distribution and poor injection performance. It is essential to improve the injectivity of single well to a satisfied level through a integrated workflow on the basis of performance analysis, brine compatibility study, core flooding experiment, strategy and solution optimization. In this paper, the injection status has been analyzed and the decisive impacting factors were given including formation properties, stimulation activity, the brines compatibility and pre-treatment of injection water, which play a very important role in injection performance sustainability as the seawater injection continues. Scale modelling was done with formation water, mud filtrate, injection water and stimulation fluid for self-scaling assessment. Mixing experiment of two of the brines of four introduced at either atmospheric or reservoir condition. Core flooding experiment was carried out with formation water and filtered injection water after critical velocity for core flooding is confirmed. Then the injectivity for each wells have been analyzed at different locations of the reservoir with different formation properties, solutions have been subsequently put forward and the improvement on injectivity of injectors before and after the stimulation or even re-stimulation and the effect of cleanup after the stimulation was also compared. It was concluded that injectivity could be enhanced through stimulation and the cleanup after stimulation and the sulfate should be removed or reduced in the process of the pre-treatment of injection water from the remote terminal to ensure desirable water injection and production performance.

Abstract
Present study is concerned with the interpretation of satellite imagery and 2D seismic profiles to understand the structural styles and petroleum system elements of the Southern Kirthar Fold Belt of Pakistan. Southern Kirthar Fold Belt is the part of regional Himalaya-Suleiman and Kirthar fold belt chain, which is produced in the Cenozoic due to collision and under-thrusting of the Indian Plate with Eurasian Plate. The exploration activities are being carried out in the study area since 19th century and number of gas discoveries are made, but many structures are still barren of hydrocarbons. Present study identifies four structural trends, which are 0, 350,330 and 020 in relation with 010 trending transpressional Ornach-Nal plate boundary. Three different styles of the studied anticlines are identified on the basis of seismic interpretation, which are anticlines cut by both fore-thrusting and back-thrusting reverse faults, anticlines cut by only fore-thrusting reverse faults and anticlines not cut by faults. Sufficient throw along the faults is identified in the seismic profiles, which can provide the juxtaposition trapping as well as recharging medium from the source to trap. Gas fields are discovered from the four out of six studied anticlines irrespective of style.
An XFEM-based CZM Numerical Strategy for Modeling Hydraulic Fracture Propagation under Different Fracturing Schemes
Authors: Zhang Hao-yu , Chen Jun-bin , Wang Yang 
Published: October 2023

Abstract
Segmented and cluster fracturing can improve the efficiency of volume stimulation in shale reservoirs and reduce construction costs. It is important to clarify the propagation characteristics of hydraulic fractures and stress interference under different fracturing techniques to optimize the process of clustered and staged fracturing. For this purpose, we have developed a 2D XFEM-based CZM hydraulic fracturing model. The capability of this model was validated by analytical solutions and then used to study the propagation paths of hydraulic fractures and the characteristics of stress interference under simultaneous fracturing, sequential fracturing, zipper fracturing and multi-cluster fracturing. The results show that in simultaneous fracturing, the middle cluster is compressed by the external position clusters, and the opening width of hydraulic fractures is reduced. In sequential fracturing, the fracture that first initiates create an additional stress field that inhibits the propagation distance of subsequent fractures and the propagation path of hydraulic fractures is also affected in the stress shadow region. Zipper fracturing can effectively alleviate stress interference between multiple fractures, and internal fractures can also propagate a certain distance. In multi-cluster fracturing, the fluid rate into the internal fractures may be limited, and fracture propagation is also limited by stress interference. Therefore, it is necessary to optimize the parameters of clusters to ensure that all clusters can initiate fractures normally. The research results are important for the parameter optimization of clustered and staged fracturing, especially for well factory fracturing mode.

Abstract
So far, many methods have been used to increase production from gas condensate reservoirs, but in general, all these methods can be placed in two groups:1) Methods of maintaining pressure or preventing pressure drop; 2) Creating chemical changes in reservoir fluids to improve production mechanisms due to capillary forces.Also, many of the methods used have realized both of the above purposes and at the same time while maintaining the reservoir pressure (or preventing pressure drop) also change the chemical physical properties of the reservoir. One of these methods is gas injection. What causes severe changes in the performance of condensate gas reservoirs as soon as the pressure reaches the dew point pressure is the change of the reservoir fluid from a single-phase gas state to a two-phase gas condensate state. In order to accurately study the fluid behavior of one of condensed gas reservoirs, the reservoir fluid was simulated by software, four samples of nitrogen gas, carbon dioxide, methane and separator gas, were injected into the reservoir and then the effect of changing injection rate, injection pressure and injection duration on gas condensate recovery has been investigated by these injection gases.

Abstract
The different stages of oil exploration, extraction, and processing, as well as its down-stream industries and the activities of refineries and petrochemical exploitation, leave multiple effects on the environment. For certain, as a result, soil, air, water (including surface and underground), organisms, plants, trees and even humans are affected by these effects. Hence, the fundamental importance of sustainable development and attention to the needs of the future generation, as well as the relevance of preventing the re-duction of environmental quality, encourages and requires oil industry and environmental experts to think of solutions and provide operational-strategic solutions to control and reduce the adverse environmental effects caused by these industries. Indeed, it is necessary to diversify control strategies and include environmental considerations in the planning of the oil, gas, and petrochemical industries, but the current situation is far from ideal. This article first briefly presents some environmental challenges and problems of the oil, gas and petrochemical industries and then describes the need for an environmental strategy to overcome these issues.
