Background: The coronavirus disease 2019 (COVID-19) vaccines are very good at protecting individuals from serious illness, needing hospital care, and dying from different strains of the virus. However, vaccines might not completely prevent individuals from catching and spreading the virus, and this might depend on some personal factors. Objectives: To find out the immune response of COVID-19 vaccines, this cross-sectional study conducted within June 2021 to May 2023 assessed different types of COVID-19 vaccine antibody responses among healthcare professionals and their associations with demographic factors and comorbidity risk factors. Methods: This descriptive-analytical study was conducted on recruited healthcare professionals from Sina, Imam Khomeini Complex, 501 AJA, Baqiayatallah, and Firoozgar hospitals in Tehran, Iran. The vaccines whose antibody response was investigated in this study are Sinopharm® (China), AstraZeneca® (United Kingdom), Sputnik® (Russia), and Covaxin® (India). Anti-spike, anti-receptor-binding domain (RBD), and anti-neutralizing immunoglobulin G (IgG) were evaluated by commercial kits according to instructions. Results: This study involved 1 029 healthcare workers who were over 18 years old. The average age was 41.48 ± 9.9 years, and 602 (58.5%) of them were male. The vaccines they received were Sputnik V (392 or 38.16%), AstraZeneca (335 or 32.61%), Baharat (45 or 4.3%), and Sinopharm (255 or 24.82%). The Covaxin and AstraZeneca vaccines increased both anti-RBD and anti-neutralizing IgG Ab levels; however, the Sinopharm vaccine increased only the latter. The Sputnik vaccine was the least effective. Gender and diabetes influenced the antibody levels, but age did not. Conclusions: This study revealed the substantial effectiveness of COVID-19 vaccines in generating robust antibody responses among healthcare professionals. All four vaccine types, Sinopharm, AstraZeneca, Sputnik, and Covaxin, elicited significant antibody responses in over 70% of participants, highlighting the crucial role of vaccination in building defense against COVID-19.

Authors: Emami Meybodi Mohammad Kazem , Shirvani Shahram , Jannesari Ladani Morteza , Mohammadnabi Sajjad , Shater Mohammad Mahdi
Published: February 2024

Background: Total hip arthroplasty (THA) is a surgical technique to correct developmental dysplasia of the hip (DDH). Various THA-based methods have been developed for managing end-stage osteoarthritis in patients with DDH Crowe type III or IV. Objectives: In this study, we evaluate the Harris hip score (HHS) before and after cementless THA without subtrochanteric shortening osteotomy (STO) in patients with DDH Crowe type III or IV who were candidates for THA, as well as complications and the need for revision surgery. Methods: This retrospective cohort study was conducted on patients with DDH Crowe type III and IV, who were candidates for cementless THA using the Watson Jones technique without shortening STO. The HHS was calculated and recorded in their medical files before surgery. Patients with missing or incomplete medical files, without written informed consent, with neurovascular diseases, immunosuppressive drug use, congenital bone and articular anomalies, low back pain radiating to the lower extremities, simultaneous fractures, a history of lower extremity fractures, or joint infections were excluded. The HHS was recalculated during outpatient follow-up. Neurovascular defects and the need for reoperation were also evaluated. All data were recorded and analyzed. Results: Thirty-two patients were enrolled with a mean ± SD age of 50.34 ± 15.45 years, most of whom were women (75%). The patients were followed for 2 to 7 years. Postoperative nerve defects were observed in only 1 (3.1%) patient. Hip reoperation was performed in 1 (3.1%) patient. The mean ± SD of HHS before surgery was 50.10 ± 12.48, which increased significantly to 77.99 ± 15.60 after surgery (P < 0.001). Furthermore, the HHS was evaluated before and after the intervention for each gender, showing a significant increase in both. Conclusions: Cementless THA without shortening osteotomy can improve HHS in patients with DDH Crowe III and IV, providing satisfactory outcomes. Furthermore, complications, such as neurological defects and the need for reoperation, are minimal with this method.
Mezi úslužností a revoltou: "Střelný prach právě nevynalezl(y)"? : korespondence spisovatelky Heleny Dvořákové Zdeňku Wirthovi
Authors: Rusinko Marcela
Published: February 2024

The functional emancipation of the professional status of women became one of the pivotal social themes of the first decade of building state socialism in Czechoslovakia. A newly discovered fragment of correspondence between the writer Helena Dvořáková (1895–1970), author of neorealistic psychologizing women's novels, and the Nestor of Czech art history and conservation Zdeněk Wirth (1878–1961) points retrospectively to this gender-oriented debate also taking place in an informal form between representatives of the post-war cultural elites. In her letter of June 1954, Dvořáková refers to a social gathering at the Olympia Café, where she witnessed a discussion between the leading art historians Zdeněk Wirth and Emanuel Poche (1903–1987), in which they questioned the contribution of women in the field of intellectual culture. In the fifty years that women have had access to higher education, "they never invented gunpowder", someone said during the discussion. As an unintended witness to the event, Dvořáková sets herself against similar accusations not only in the correspondence under review, but above all in her literary work, the leitmotif of which became the fortunes and social status of – among others – educated, academically established – women.
Using neuro-linguistic programming and transactional analysis tools to measure the English proficiency of foreign language learners
Authors: Almosa Abdulrahman
Published: February 2024

Various methods are used to evaluate the English skills of non-native learners. Two approaches within cognitive science have garnered attention lately due to their potential usefulness in learning a foreign language and improving an individual's interpersonal and communicative skills. They include Transactional Analysis (TA) and Neuro-Linguistic Programming (NLP). Self-improvement, psycho-education, and language teaching extensively use these psychological methods for assessing and evaluating students' behaviour. Communication skills, such as consciousness, fearlessness, and others, are essential to teach English in the classroom and can be trained through methods like NLP and TA. This study focused on measuring different variables that underpin proficiency in a foreign language. The six variables measured in this study include speaking, listening, reading, and writing skills. Grammar and vocabulary proficiency were also measured. The measuring instrument was the NLP and TA tools, and the method adopted for the study is an experimental approach. Two hundred high school students participated in both the pretest and posttest. Both the researcher and some selected teachers administered the tests. The findings of the study affirm that the participants generally performed better across the skill sets for proficiency in the posttest, more than what is seen in the pretest. This indicates that the tools help measure and facilitate learning different FL proficiency skills. The study further revealed that the students performed better during the posttest in the TA test than in the NLP test. The findings also indicated that the students performed better in speaking and listening skills in both the posttests of NLP and TA tests. It is thus concluded that TA and NLP are critical tools to measure students' progress in certain areas of FL learning.

Applications of Differential-Difference Algebra in Discrete Calculus
Authors: Fiadh Mahmood Salim , Mohammed Mostafa Abdulghafoor
Published: February 2024

Discrete calculus deals with developing the concepts and techniques of differential and integralcalculus in a discrete setting, often using difference equations and discrete function spaces. This paperexplores how differential-difference algebra can provide an algebraic framework for advancing discretecalculus. Differential-difference algebra studies algebraic structures equipped with both differential anddifference operators. These hybrid algebraic systems unify continuous and discrete analogues ofderivatives and shifts. This allows the development of general theorems and properties that cover bothsettings. In particular, we construct differential-difference polynomial rings and fields over discretefunction spaces. We define discrete derivatives and shifts algebraically using these operators. We thenstudy integration, summation formulas, fundamental theorems, and discrete analogues of multivariatecalculus concepts from an algebraic perspective. A key benefit is being able to state unified theorems indifferential-difference algebra that simultaneously yield results for both the continuous and discretecases. This provides new tools and insights for discrete calculus using modern algebraic techniques.We also discuss applications of representing discrete calculus problems in differential-differencealgebras. This allows bringing to bear algebraic methods and software tools for their solution. Specificexamples are provided in areas such as numerical analysis of discrete dynamical systems definedthrough difference equations. The paper aims to demonstrate the capabilities of differential-differencealgebra as a unifying framework for further developing the foundations and applications of discretecalculus. Broader connections to algebraic modeling of discrete physical systems are also discussed.

In an international context where states seek to diversify their means of external projection, consistent with their traditionalism, Russia maintains a traditional vision of power. In this context, the Wagner Group has emerged as a new instrument that can be used in the pursuit of Russian interests and objectives abroad. Through a comparative case study that draws on Western and Russian academic and journalistic sources, as well as Russian strategic and legal documents, the research aims to understand the role of the Wagner Group in Russian foreign policy. To this end, we begin by investigating the concept of a private military company, then we look into the Group’s origin, history of operations and modus operandi. In addition, we identify other ‘Western’ private military companies and compare their activities and the level of scrutiny they receive in relation to the Russian group. We conclude our research by identifying attempts by international law to respond to the emergence of Wagner and other private military groups.
The Pathways to the war in Europe | Os caminhos da guerra na Europa
Authors: Montalvão Sarmento Cristina
Published: February 2024

War broke out in Europe when Europeans were convinced of their lasting peace, based more on ideas than reality. Pacifism, the dream of Europeans in the 60s and 70s, was replaced by the violence of conflict. Analysts, historians, militaries, sociologists and other commentators on war have found it difficult to deal with the novelty of a nationalist war of defense in a global world. The global turn in political theory has been put to the test. In its analytical capacity, in the normative projection of the desired world in the face of the strategic and political reality of resources, multilateralism and the emergence of new global actors. The Wider West or the Global South are examples of emerging concepts whose substantive meaning has yet to be clarified. This issue of Political Observer aims to contribute to the debate, and provide a historical record of the emergence of the present of the war, sometimes contextualizing the past in order to clarify some of the vectors of the analyses that will follow in a future perceived as uncertain, for which this opening paper provides a first viewpoint sustained by some further readings mentioned at the end, which are essential to understanding the conflict.
The Air Iron Curtain of the 21st Century: the Ukraine of the Air | A Cortina de Ferro Aérea do Século XXI: as Ucrânias do Ar
Authors: Garrido Jorge
Published: February 2024

“Ukraine” means borderland and the concept of border encompasses the notion of lines that determine the land, sea and air spaces of sovereignty and responsibility of all Nation-States. As so, we can argue that aerial ukraines are defined by the so-called Flight Information Regions (FIR). The Nation-States or the groups of Nation-States should guarantee the safety and assistance ofaircraft operating in their respective FIR. However, they can also close them for national security reasons, especially in cases of war, or use them as political and geopolitical tools, to obtain advantages over other Nation-Sates, namely their opponents. By studying the main events regarding aviation’s history like the first international flight and the events occurred since the 2004 presidential elections in Ukraine and the political decisions regarding sanctions, this article addresses the effects of the Ukrainian war on the Eurasian aviation, discussing, among other themes, the geographical, geopolitical, social, and economic implications. After three decades of globalization, it was perhaps inconceivable to return to a world of closed skies. However, that reality is back and even if it isn’t transversal to the entire world, the political weight of the rise of an aerial iron curtain of the 21st century is undeniable.

Authors: Ardiyantoro Bagas , Merari P Ason , Mardiyono Mardiyono
Published: February 2024

The stem of Brotowali and the rhizome of Temulawak are among the ingredients used in the production of traditional herbal medicine, specifically Brotowali and Temulawak herbal concoctions. These herbal mixtures are also consumed by pregnant women. The extracts from Brotowali stem and Temulawak rhizome contain bioactive antioxidants of the flavonoid group. Flavonoid compounds can inhibit the activities of phosphodiesterase enzymes that hydrolyze cAMP, and an elevated concentration of cAMP can impede growth acceleration. The aim of this research is to determine the teratogenic effects on white mouse fetuses after the administration of Brotowali stem and Temulawak rhizome extracts. The study involved 49 white mice (Mus musculus) divided into 5 groups. The first test group was given 0.5% Na CMC and used as the negative control, the second test group was injected with intravenous Cyclophosphamide at 50 mg/kg BW for the positive control. The groups included EB Dose 1120, ET Dose 1120, Dose 1 EBT 2:1, Dose 2 EBT 1:2, and Dose 3 EBT 1:1. Brotowali stem and Temulawak rhizome extracts were administered during the organogenesis period, and on the 18th day, the mice were subjected to laparotomy to collect the fetuses. Biometric, gross morphological, and skeletal abnormality observations were conducted to assess the effects of Brotowali stem and Temulawak rhizome extract administration. The research results indicate that Brotowali stem and Temulawak rhizome extracts have the potential to cause teratogenic effects, particularly at Dose 3 EBT 1:1.
Load Frequency Control of One and Two Areas Power System Using Grasshopper Optimization Based Fractional Order PID Controller
Authors: Mohammed A. S. , Dodo A.
Published: February 2024

In this paper, grasshopper optimization based fractional order PID controller for load frequency control of single and multi-area power system is presented. It is paramount to minimize large frequency deviation in power system control. Large frequency deviation occurs when the parameter values of the various generating units of the power system like generators, turbine and governors keeps changing due to numerous on/off witching in the load side. As such, for a more realistic study, nonlinearities and boiler dynamics has been introduced into the power system design and measures also put in place to mitigate large frequency deviation. This is because large frequency deviation can damage equipment at the generation level and the consumer devices at the distribution level. Anti-windup control will then be used to compensate the effects of the nonlinearities. The gain of the FOPID controller will be optimized using grasshopper optimization algorithm and objective function for minimization is the Integral Square Error (ISE). The Errors to be minimized are the summation of frequency deviation, tie-line power deviation and the area control errors. Simulations were carried out on the designed power system using MATLAB/Simulink and results obtained show a significant improvement in mitigating frequency deviation. However, the proposed method took a longer time to balance the generated power and load demand. This is because the proposed method considers boiler dynamics and nonlinearities in the power system designed and results were compared with other designed method for power system without nonlinearities.

Ultimately Bounded TSK Fuzzy Management in Urban Traffic Stream Mechanism: Multi-Agent Modeling Approach
Authors: Ghasemi Reza , Hazaveh Negin Amiri
Published: February 2024

In this paper, a novel control approach based on the selection of the type of traffic light and the period of the green phase to accomplish an optimum balance at intersections is proposed. This balance should be flexible to the static behavior of time, and randomness in a traffic situation, which the goal of the proposed method is to reduce traffic volume in transportation, the average delay for each vehicle, and control over the crash of cars. The proposed method was specifically investigated at the intersection through an appropriate timing of traffic lights by sampling a multi-agent system. It consists of a large numbers of intersections, each of which is considered as an independent agent that exchanges information with each other, and the stability of each agent is provided separately. The robustness against uncertainties, scalability, and stability of the closed-loop overall system are the main merits of the proposed methodology. The simulation results show that the fuzzy intelligent controller in this multi-factor system which is a TS fuzzy is more useful than scheduling in the fixed-time method and it reduces the lengths of vehicles queuing.

Published: February 2024

This paper proposes a cost-effective solution through a recompletion design of sand control to restart the production of a dead well named "X" (for confidential reasons). The data used to achieve the objective of this paper are the production parameters, reservoir properties and the previous completion design. The tool used to draw the new completion schematic is Power Drawn software. It is necessary to use two softwares (PowerDrawn and Pipesim), Ishikawa method and economic evaluation method. The different causes that probably contributed to the production stop in well X are given by using the Ishikawa diagram. The top sediment is obtained by using the sonic log and the clean-up is performed by using coiled tubing with a drill bit incorporated at the end. The mechanical packer is installed to isolate the formation, the pre-packed screen allows the filtration of hydrocarbons. The on-off tool ensures the installation of the mechanical packer and the minimum restriction for the passage of the equipment through the ones in place is 2.313 inches. After the installation of the recompletion, a positive return on investment is obtained and after a production time of one week. The financial aspect after installation of the recompletion shows that a recompletion of the sand control at lower cost is achieved.

Published: February 2024

This research delves into advanced control methodologies by investigating the intricate applications of Proportional-Integral-Derivative (PID) control for achieving precise and dependable temperature regulation within electric water heaters. The study delves into various control strategies, namely Proportional, Proportional-Integral, and Proportional-Integral-Derivative methodologies, to realize the pinnacle of stable and exacting temperature control. The Proportional Controller, operating with a Kp value of 10, stands out with its relentless performance, characterized by minimal overshoot and an inconsequential steady-state error. Implementing the Proportional-Integral Controller, synergizing Kp at 10 and Ki at 5, elevates system stability while deftly curbing any hint of overshoot. The dynamic interplay between the Kp, Ki, and Kd parameters in the Proportional-Integral-Derivative (PID) Controller unveils an intricate dance of precision and control. Notably, configurations involving Kp 10, Ki 5, and Kd 2 emerge as beacons of rapid stabilization, heightened precision, and masterful overshoot management, exemplified by a rise time of 119.3543 seconds, settling time of 162.6116 seconds, overshoot of 1.0299%, peak time of 216 seconds, and a commendably low steady-state error of 0.31. This extensive exploration bears testament to its instrumental role in optimizing PID control strategies, ushering in augmented efficacy and pinpoint accuracy in water temperature regulation across an expansive spectrum of applications. As a result, these findings pave the way for the evolution of control methodologies that transcend theoretical confines and manifest within practical scenarios with profound impact.
Fully Homomorphic Encryption Scheme Over Integers Based on DGHV Scheme
Authors: Mahmood Zainab H. , Ibrahem Mahmood K.
Published: February 2024

Homomorphic encryption was introduced to enable untrusted parties to apply computation over encrypted data, without decrypting the message. It makes a promising future to solve security challenges with Cloud Computing.  Still, because of complex problems, HE is not yet usable in real-world applications. However homomorphic encryption suffers from many complex issues like large-time computation, which is difficult to implement, and huge ciphertext size. In this paper, we take into account many vital homomorphic encryption schemes, all of them is depend on computing over integers, by converting the message to a binary format, then the ciphertext is calculated to every single bit of plaintext. So, we suggested another symmetric Fully Homomorphic encryption that depends on an integer number without converting it to binary format, it encrypts the message using a prime secret key. The proposed system is considered a great improvement to the DGHV system. Where it reduced the ciphertext size and the execution time significantly. The present proposed system shows an improvement of DGHV where it is faster about 23.8 times from DGHV, and we gain one ciphertext for the whole message instead of ciphertext for every bit of the message. The scheme's hardness depends on the greatest common divisor (GCD) problem. We present a detailed explanation of these schemes showing their efficient techniques and compare it with the proposed algorithm in terms of ciphertext size of algorithm, and execution time and analyze their security them finally draw several conclusions.

Low carbon integrated vehicles and buildings
Authors: Kendall Kevin
Published: February 2024

This paper defines vehicles and buildings as main sources of United Kingdom (UK) carbon dioxide (CO2) and seeks to cut such emissions using green hydrogen made from combined wind and solar energy. Combustion vehicles powered by fossil petroleum emit near half of UK climate-warming CO2 while buildings heated by natural gas provide a third. First, current UK grid problems are defined: Electricity, gas and petroleum grids. Refueling green vehicles has been a particular problem. Then experiments on the private wire community of Keele University show how green hydrogen could integrate both green vehicles and buildings. Next, the model supply chain is planned and tested. Finally, experiments and calculations are outlined, analyzing the optimum system design criteria proposed. We conclude that economic green hydrogen can displace petroleum in vehicles, while powering buildings instead of natural gas. Also, the prospect in 2024 is that profits can be made all along the green hydrogen supply chain, such that new businesses involved in local private clean communities can cost less than the National Grid monopoly and other dominant fossil energy companies.
