Authors: Mishra Nidhish Kumar , AlBaidani Mashael M. , Khan Adnan , Ganie Abdul Hamid
Published: March 2023

This paper examines two methods for solving the nonlinear fractional Phi-four problem with variable coefficients. One of the distinct states of the Klein–Gordon model yields the Phi-four equation. It is also used to simulate the kink and anti-kink solitary wave connections that have recently emerged in biological systems and nuclear particle physics. The approaches that are being suggested consist of the Yang transform, the homotopy perturbation approach, the decomposition approach, and the fractional derivative as stated by Caputo. The advantages of the proposed techniques are their capability of combining two dominant approaches for attaining precise and approximate solutions of nonlinear equations. It is important to keep in mind that the suggested methods can perform better in general as they need less computational effort than the alternative methods, while keeping a high level of numerical precision. The actual and estimated outcomes are demonstrated in graphs and tables to be quite similar, demonstrating the usefulness of the proposed approaches. Additionally, several simulations are used to show the physical behaviors of the found solutions with regard to fractional order. The article’s results possess complimentary properties that relate to the symmetry of partial differential equations.
Acoustic Metamaterial Design by Phase Delay Derivation Using Transfer Matrix
Authors: Kim Hyunsu , Kwon Yoonjung , Lee Sangwoo
Published: March 2023

When acoustic elements such as quarter-wave, Helmholtz, labyrinthine-type or hook-type resonators are arranged sequentially, sound waves can be refracted in a specific frequency range. Thus, a metasurface may be designed to reduce noise by locating two sequentially arranged acoustic elements symmetrically. Phase delay, which can be calculated with a transfer function of the acoustic element, needs to be obtained to decide on acoustic element design parameters. However, in the case of a complex structure with labyrinthine-type or hook-type resonators, it can be difficult to calculate the phase delay accurately because each designer may have a different estimation method for the propagation direction of the sound wave. Therefore, this study presents a method for accurately deriving the phase delay required when designing a metasurface with a complex structure. The phase delay was calculated using the pressure and velocity derived from FEM and the transfer matrix of the main duct. Using the proposed method, a metasurface with symmetrically arranged acoustic elements was designed, and the noise reduction effect was confirmed through a speaker test. This study could be very helpful, since through it, any kinds of complex acoustic elements are able to be designed with accurate phase delay calculations.

Published: March 2023

The Earth’s magnetospheric cusp, a region with an off-equatorial magnetic field minimum, is an important place which directly transports plasma and energy from the solar wind into the magnetosphere and ionosphere. Its magnetic topology and charged particles therein are known to respond to the solar wind and the interplanetary magnetic field. However, its dynamics in response to the interplanetary (IP) shock are still unknown, due to lack of direct spacecraft observations. This study first reports the observations of the cusp’s motion under the drive of an IP shock and both strong electric fields and outflowing energetic ions in the moving cusp. After an IP shock arrival on 7 September 2017, triple cusps were observed by Cluster C4 when it was crossing the high-altitude northern polar region to the sub-solar magnetosphere. The multiple cusps had a one-to-one correspondence with the dayside magnetosphere compression and relaxation detected by THEMIS E, indicating that one cusp moved back and forth three times due to the IP shock’s impact. In the moving cusp, there were strong impulsive electric fields with a peak of up to ∼40 mV/m and an ionospheric source population of upward propagating ions (O+, He+ and H+) with energies extending to MeV. However, the outflowing ions outside the cusp had energies of no more than 1 keV. An enhancement of energetic O+ appeared inside the cusp with the flux ratio of O+/H+ increasing from 10 keV to ∼ MeV, which implies the efficient acceleration of O+. These observations are shown to be consistent with the prompt acceleration by the impulsive electric fields, which is mass-dependent. This finding suggests a new acceleration mechanism for cusp energetic ions, especially for O+.

In patients with multiple myeloma (MM), SARS-CoV-2 infection has been associated with a severe clinical course and high mortality rates due to the concomitant disease- and treatment-related immunosuppression. Specific antiviral treatment involves viral replication control with monoclonal antibodies and antivirals, including molnupiravir and the ritonavir-boosted nirmatrelvir. This prospective study investigated the effect of these two agents on SARS-CoV-2 infection severity and mortality in patients with MM. Patients received either ritonavir-nirmatrelvir or molnupiravir. Baseline demographic and clinical characteristics, as well as levels of neutralizing antibodies (NAbs), were compared. A total of 139 patients was treated with ritonavir-nirmatrelvir while the remaining 30 patients were treated with molnupiravir. In total, 149 patients (88.2%) had a mild infection, 15 (8.9%) had a moderate infection, and five (3%) had severe COVID-19. No differences in the severity of COVID-19-related outcomes were observed between the two antivirals. Patients with severe disease had lower neutralizing antibody levels before the COVID-19 infection compared to patients with mild disease (p = 0.04). Regarding treatment, it was observed that patients receiving belantamab mafodotin had a higher risk of severe COVID-19 (p < 0.001) in the univariate analysis. In conclusion, ritonavir-nirmatrelvir and molnupiravirmay prevent severe disease in MM patients with SARS-CoV-2 infection. This prospective study indicated the comparable effects of the two treatment options, providing an insight for further research in preventing severe COVID-19 in patients with hematologic malignancies.

COVID-19 has been considered a vascular disease, and inflammation, intravascular coagulation, and consequent thrombosis may be associated with endothelial dysfunction. These changes, in addition to hypoxia, may be responsible for pathological angiogenesis. This research investigated the impact of COVID-19 on vascular function by analyzing post-mortem lung samples from 24 COVID-19 patients, 10 H1N1pdm09 patients, and 11 controls. We evaluated, through the immunohistochemistry technique, the tissue immunoexpressions of biomarkers involved in endothelial dysfunction, microthrombosis, and angiogenesis (ICAM-1, ANGPT-2, and IL-6, IL-1β, vWF, PAI-1, CTNNB-1, GJA-1, VEGF, VEGFR-1, NF-kB, TNF-α and HIF-1α), along with the histopathological presence of microthrombosis, endothelial activation, and vascular layer hypertrophy. Clinical data from patients were also observed. The results showed that COVID-19 was associated with increased immunoexpression of biomarkers involved in endothelial dysfunction, microthrombosis, and angiogenesis compared to the H1N1 and CONTROL groups. Microthrombosis and vascular layer hypertrophy were found to be more prevalent in COVID-19 patients. This study concluded that immunothrombosis and angiogenesis might play a key role in COVID-19 progression and outcome, particularly in patients who die from the disease.

Objectives: The objective of this prospective study was to investigate the role of adaptive immunity in response to SARS-CoV-2 vaccines. Design and Methods: A cohort of 677 vaccinated individuals participated in a comprehensive survey of their vaccination status and associated side effects, and donated blood to evaluate their adaptive immune responses by neutralizing antibody (NAb) and T cell responses. The cohort then completed a follow-up survey to investigate the occurrence of breakthrough infections. Results: NAb levels were the highest in participants vaccinated with Moderna, followed by Pfizer and Johnson & Johnson. NAb levels decreased with time after vaccination with Pfizer and Johnson & Johnson. T cell responses showed no significant difference among the different vaccines and remained stable up to 10 months after the study period for all vaccine types. In multivariate analyses, NAb responses (<95 U/mL) predicted breakthrough infection, whereas previous infection, the type of vaccine, and T cell responses did not. T cell responses to viral epitopes (<0.120 IU/mL) showed a significant association with the self-reported severity of COVID-19 disease. Conclusion: This study provides evidence that NAb responses to SARS-CoV-2 vaccination correlate with protection against infection, whereas the T cell memory responses may contribute to protection against severe disease but not against infection.
A Comprehensive Review on Bacterial Vaccines Combating Antimicrobial Resistance in Poultry
Authors: Islam Md. Saiful , Rahman Md. Tanvir
Published: March 2023

Bacterial vaccines have become a crucial tool in combating antimicrobial resistance (AMR) in poultry. The overuse and misuse of antibiotics in poultry farming have led to the development of AMR, which is a growing public health concern. Bacterial vaccines are alternative methods for controlling bacterial diseases in poultry, reducing the need for antibiotics and improving animal welfare. These vaccines come in different forms including live attenuated, killed, and recombinant vaccines, and they work by stimulating the immune system to produce a specific response to the target bacteria. There are many advantages to using bacterial vaccines in poultry, including reduced use of antibiotics, improved animal welfare, and increased profitability. However, there are also limitations such as vaccine efficacy and availability. The use of bacterial vaccines in poultry is regulated by various governmental bodies and there are economic considerations to be taken into account, including costs and return on investment. The future prospects for bacterial vaccines in poultry are promising, with advancements in genetic engineering and vaccine formulation, and they have the potential to improve the sustainability of the poultry industry. In conclusion, bacterial vaccines are essential in combating AMR in poultry and represent a crucial step towards a more sustainable and responsible approach to poultry farming.
EU Member States’ Institutional Twitter Campaigns on COVID-19 Vaccination: Analyses of Germany, Spain, France and Italy
Authors: Tuñón Navarro Jorge , Oporto Santofimia Emma
Published: March 2023

The development of an effective vaccine against the SARS-CoV-2 coronavirus became the hope for halting the spread of the disease. In recent years, social networks have become important tools for political and strategic communication in the dialogue with citizens. Therefore, the messages emitted through them were important to address vaccine hesitancy and achieve collective immunity. This paper analyses the use of Twitter by politicians and institutions in EU Member States during the first fifty days after the Commission’s marketing authorisation of the first COVID-19 vaccine (21 December 2020 to 8 February 2021). To do so, a triple approach content analysis was carried out (quantitative, qualitative and discursive on feelings) applied to 1913 tweets published by the official profiles of the prime ministers, health ministers, governments and health ministries of Germany, Spain, France and Italy, the four most populous EU countries. The results point out that politicians and institutions gave preference to other issues on their political agenda over vaccine-related issues. Moreover, previous research hypotheses, such as those related to the underutilization of the Twitter tool as a two-way communication channel with citizens, are validated.

Authors: Legler Marko , Guddorf Vanessa , Fehr Michael
Published: March 2023

A 3-year-old male northern goshawk (Accipiter gentilis) used in falconry for hunting was diagnosed with a craniodorsal coxofemoral luxation of the left leg after an unsuccessful hunting flight. Closed reduction in the dislocation was unsuccessful and the hip joint reluxed again with slight abduction of the limb. An open surgical reduction with a transarticular stabilization using a normogradely inserted Kirschner wire was performed. The implant was removed surgically after five weeks. After about seven weeks, the owner saw no abnormalities in the loading of the limbs, and the goshawk was successfully used for hunting after nine months in the next hunting season.
An Expanded Interpretive Structural Modeling Analysis of the Barriers to Integrated Flood Risk Management Adaptation in Metro Manila
Authors: Mercado Jean Margaret , Kawamura Akira , Medina Reynaldo
Published: March 2023

The implementation of integrated flood risk management (IFRM) is still in its infancy in both developed and developing countries, yet some countries have already encountered barriers to IFRM adaptation. The interrelationships between these barriers need to be determined and analyzed systematically, as such an analysis is the groundwork for decision-making when devising solutions to overcome the barriers. Interpretive Structural Modeling (ISM) is a popular and systematic method for analyzing the interrelationship between variables in broad study areas. This study applies the proposed expanded ISM (Ex-ISM) approach to comprehensively analyze the interrelationships between the barriers to IFRM in Metro Manila. Ex-ISM enhances conventional ISM in that the symbolism is modified to explicitly show the contextual interrelationships, the step for hierarchy assignment is simplified, and the diagram shows all of the interrelationships that allow a comprehensive analysis. The results obtained using the Ex-ISM method do not deviate from those yielded by the conventional ISM method, but the Ex-ISM method allows an easy assignment of hierarchy, and it shows not only the direct but also the indirect interrelationships to provide a comprehensive analysis of the relationships between the barriers.
A Spreadsheet Tool for Defining Dangerous Flow Ranges of Low-Head Dams
Authors: Wahl Tony L. , Svoboda Connie D.
Published: March 2023

Low-head dams can be dangerous to recreational river users when a submerged hydraulic jump forms downstream, with recirculating surface flows that repeatedly carry trapped recreationists upstream into the high-velocity jet plunging over the dam crest. The flow endangers those who pass over the dam from upstream and can also entrap those who approach too closely from downstream. A national task force is using a range of methods to identify potentially dangerous structures, but definite determination requires field data and an analysis of the hydraulic conditions for each site’s range of likely flow rates. The spreadsheet tool described here determines the submergence created by site-specific tailwater levels and uses previous research results to estimate the associated magnitude of reverse flow velocities. The spreadsheet also determines the crucial tailwater level at which the jet passing over the dam stops plunging into the tailwater pool and instead flips to the surface, creating safer, downstream-directed velocities. The article describes application to specific sites and provides insight about the dangerous flow range of typical low-head dams.
Analysis of the Dynamics and Characteristics of Rice Stem Tillers via Water Level Management

Published: March 2023

Based on theoretical analysis and numerical calculations, this study systematically investigated the changes in rice tillering dynamics and the simulation of stem tiller growth during the tillering stage using the farm water level as a regulation index for rice irrigation and drainage. Based on pit testing, the results of this study show that both flooding and drought in the tillering stage suppress the tiller output of rice and have a certain compensating effect following rehydration. Heavy drought during the tillering period reduced the effective tiller rate, while flooding and light drought had little effect on the effective tiller rate. Flooding and maintaining a high infiltration rate also increased the effective tiller rate. The primary kinetic model of tiller elongation (DMOR) was a good fit for the tiller elongation process (coefficients of determination of 0.99 or higher). In addition, the growth and extinction rates of the stem tiller extinction curves were fitted. The maximum growth rate of the stem tiller growth segment was ranked as CK > L1 > H1 > L2 > H2, and the maximum extinction rate of the stem tiller extinction segment was ranked as CK > H2 > H1 > L2 > L1, indicating that both flooding and drought during the tillering stage could reduce the growth and extinction rates of the stem tiller. This shows that both flooding and drought can reduce the growth and extinction rates of tillers.

Published: March 2023

When the Surface-Mounted Permanent Magnet Synchronous Motor (SPMSM) is in the condition of high-speed and low carrier-wave ratio, the performance of sensorless control is more affected by digital control delay, parameter inaccuracy, and other factors. This paper presents a sensorless control method based on the static error between the discrete d-axis current and the corresponding reference value. If there is no error in position angle, the discrete d-axis current should have no static error approximately. In addition, the static error of the d-axis current is related to the speed, so the PI controller with a variable proportional integral coefficient is used to ensure a stable error compensation performance in a wide speed range. The proposed method can accurately compensate the estimated rotor position of the motor under high-speed and low carrier ratio conditions and improve the accuracy of sensorless control. It provides an effective measure for the stable and reliable acceleration of electric vehicles and has specific practical significance for the development of electric vehicle control.

PRODUCTION OF BIOFUEL COMPONENTS FOR MARINE POWER PLANTS
Authors: Gromakov A , Fil' A.
Published: March 2023

The article discusses the prospects for the use of biofuels as an alternative fuel for marine diesel engines. The

results of the analysis of applied technologies for the production of biodiesel are presented. The expediency of

using a hydrodynamic mixer as a device that ensures the intensity of the transesterification reaction in the

production of biodiesel is substantiated. A technological scheme of a laboratory plant for the production of

biodiesel has been developed. The results of laboratory studies to determine the optimal material balance of the

transesterification reaction for the production of biodiesel in a plant equipped with a hydrodynamic mixer are

presented. The main indicators of the interesterification reaction (viscosity, flash point, sediment height) for a

plant equipped with a hydrodynamic mixer have been determined. The optimal mass ratio of the transesterification

reaction has been established, which ensures the best quality indicators of the resulting biodiesel and

allows evaluating the efficiency of the hydrodynamic mixer used in the plant. Recommendations are given on

the ratio of vegetable oil and methanol in the production of biodiesel. The best oil/methanol ratio, in terms of

biodiesel yield and quality, is 7.5:1. The use of traditional petroleum fuels mixed with biodiesel can be seen as

an effective way to reduce air pollution from ships and ensure compliance with the rules of the International

Maritime Organization

diagnostics. the method of carrying out maintenance and repair on the principle of operating the mechanism

was described, according to the documentation of the shipowners' companies, which is currently in use. The

analysis of possible updating of methods of monitoring and technical diagnostics of systems of ship power

plants, as well as the necessary mechanisms to ensure the normal operation of the vessel is carried out. This

method allows you to carry out maintenance and repair, as necessary, in advance before the mechanism is

disabled, without relying on the operating time of the mechanisms. Updating monitoring systems and maintenance

will increase the operating time of the mechanisms. In addition, when implementing this method on

autonomous vessels in the future, it will allow for a much faster response to a possible failure of the mechanism,

which in turn will minimize the downtime of the vessel
INSTALLING A HYBRID ENERGY BALANCE SYSTEM ON A PORT-CONTAINER SHIP
Authors: Vasilescu M.-V. , Epikhin A
Published: March 2023

Maritime Organization (IMO)" gived different amendments in order to reduce the polluting emissions produced

by ships.There is a natural and continuous concern to reduce marine pollution and to implement the requirements

stipulated by Annex VI of the International Convention for the Prevention of Pollution of the Marine

Environment - MARPOL; The emission of carbon dioxide C02, in the gases resulting from naval propulsion

engines, has alarming values, considering that C02 is the main negative factor in producing the greenhouse

effect and implicitly global warming. Shipbuilders are aware that ship engines emit harmful exhaust gases and

certain chemical compounds that are dangerous to human health and to the environment. One way for reducing

pollution is by using unconventional energies captured from the marine environment, outside the ship, like solar

or wind, which lead to the saving of a part of the fossil fuels and lubricants consumed on board the ships.

Indirectly in this way earth's fossil fuel reserves can also be preserved. In this paper, we have studied a hybrid

system formed from non-conventional electricity generating systems (a Flettner Balloon and four large vertical

wind turbines) and a conventional one which uses fossil fuel. The non-conventional electricity generating system

captures and uses the wind energy. The existence of two systems on board, the reactive, classical and the

active, coming from wind energy, gives the possibility that in the event of failure o f one of them, the other can

be used. Also, the existence of the two independent electricity generating systems makes it possible to carry

out overhauls and repairs without the ship being stationary or adrift during them; The article main points are:

the elements of the hybrid energy system, placing the Flettner helium Balloon on a container ship as an alternative

power source of energy, placing four large vertical wind turbines on a container ship as an alternative

source of energy, energy balance of electricity generating systems, from non-conventional sources, connecting

conventional and non-conventional power sources to the ship's main power bar, electrical load of the ship's

consumers, conclusions

Published: March 2023

The article considers current main activities of the Office of the United Nations High Commissioner for Refugees in Ukraine. Refugee status is determined in accordance with the Law of Ukraine "On Refugees and Persons in Need of Subsidiary or Temporary Protection", as well as the process of granting this status, their registration and protection. The age, sex and territorial characteristics of refugees in Ukraine are provided, according to the statistics of the State Migration Service. It was also analyzed the legal mechanism of obtaining refugee status and the readmission procedure in Ukraine, which is regulated by state legislation and bilateral agreements. Lack of public funding, low level of staff competence and imperfect legal framework are considered as the main obstacles for UNHCR. It is determined that the repatriation process is a unique phenomenon in Ukrainian realities. It is emphasized that there are not enough temporary accommodation facilities both for refugees (asylum seekers) for foreigners and stateless persons who are illegally staying in Ukraine. The activities of UNHCR in the context of the COVID-19 pandemic are analyzed. Imposed quarantine restrictions are determined as the major difficulty for refugees and asylum seekers, leading to the closure of most countries' borders and impaired access to public services and information. Certain measures taken by Ukraine to protect people UNHCR serves were described. The characteristic of simplification of the procedure for issuing a temporary residence permit in a pandemic is given. The manifestation of UNHCR humanity in the context of the COVID-19 outbreak, when the entire population of the world becomes vulnerable is analyzed. Emphasis is placed on the basic principles of action in such a situation, including access to health care, which should be accessible and inclusive for the whole population without discrimination and xenophobia. It is concluded that the United Nations High Commissioner for Refugees in Ukraine is one of the main humanitarian actors in the field of protection. It is noted that significant changes in the Ukrainian legal framework indicate an improvement in the functioning of the national protection system and are in line with international law.
Attempt of collectivization of ukrainians of Zakerzonia, deported from Poland to Donetsk region (based on records management documents of local authorities)
Authors: Shypik Natalia ,   Mariupol State University
Published: March 2023

The article contains analysis of the mechanism which was implemented by local party and soviet authorities to involve resettlers into kolkhozes of Donetsk region. Some of the documents analyzed by the author are introduced into scientific circulation for the first time. The author came to the conclusion that local party and soviet authorities implemented a number of agitational / propaganda measures, used moral and material incentives, implemented restrictions on unauthorized departure from the districts of the region. An important component of the mechanism was, first of all, their placement on the territory of kolkhozes. The material incentive was the endowment with a larger plot of homestead land and in some cases a priority in the provision of housing. However, homestead land mostly did not compensate for the land that the settlers had before moving. Land left in Poland and mentioned in the property descriptions was not evaluated or reimbursed. The level of wages on the collective farms was insufficient to support the family. The process of socialization of livestock caused a negative reaction. Under such conditions, neither moral encouragement nor a ban on leaving places of residence could deter the resettlers. The party leadership cooperated with the regional department of state security, which monitored the moods and intentions of the displaced persons. The level of effectiveness of local government measures was reduced by elements of social interaction of resettlers and their development of survival practices. The bulk of the settlers expressed their rejection of the collective farm system as such and "voted with their feet" against it. The resettlers mostly went to the western regions of Ukraine, hoping for the opportunity to run the farm individually. Some of them tried to return to Zakerzonia.
ABOUT THE WINDING STRUCTURES OF WINDING PACKAGES, THEIR NAMES AND THEIR APPLICATIONS IN THE REINFORCEMENT OF COMPOSITE MATERIALS

Published: March 2023

The article reveals the content of the concept of the degree of winding closure. Winding structures of various degrees of closure have a number of exceptional properties in terms of strength characteristics and structural indicators. One of the most promising areas of application of structures amenable to strict calculation is the reinforcement of carbon-carbon composite material blanks. The possibility of maximum filling with carbon fibre of the total volume of carbon-carbon composite blanks can significantly increase the strength and physic-mechanical properties. As a result of the study, the angle of shift between the turns of different pairs of winding layers is the main criterion determining the structure of the winding threads for packing. The use of winding packages with a given degree of winding closure significantly expands the options for solutions for the formation of structural materials with the required properties. The authors come to the conclusion that closed winding structures with a honeycomb structure should be used for reinforcing composites with the required porosity and permeability.

The article presents the conclusion of analytical dependences characterising the conditions of optimal energy loss in an asynchronous electric motor for starting a machine unit equipped with an adjustable sliding link. It is shown that in the case of using adjustable sliding links in the kinematic drive chain and with significant inertia of the driven links, it is advisable to withstand the conditions of optimal start-up of the machine unit in terms of energy losses in the electric motor. To fulfill these conditions, it is necessary to maintain the high-speed mode of the asynchronous electric motor at the second stage of starting the machine unit, in which the energy losses in the asynchronous motor, on which its heating depends, will be minimal. Taking into account all factors affecting the movement of the adjustable sliding links will reduce the intensity of the machine unit start-up process.

The paper investigates the influence of the width of the partition in the cloisonne technique of artistic enameling on the appearance of jewelry. Calculations are given for small, medium and large-sized products with ornaments of varying complexity, demonstrating how a change in the width of the partition affects the change in the areas of the metal and enamel surfaces of the decorated product. It is shown how a sequential increase in the width of the partitions by 0.1 mm affects an increase in the area of the metal and a decrease in the area of the enamel, respectively. Conclusions and recommendations on the choice of the width of partitions depending on the size and complexity of the ornament of the designed jewelry are formulated.

Published: March 2023

The present study explores Saudi EFL male and female university students’ standpoints on language learning demotivation which can reduce their motivation to foreign language learning. It also attempts to identify the most and least demotivating dimensions/factors of EFL Saudi male and female university students and to find out if there are statistically significant differences between male and female students in EFL demotivation dimensions/factors or not. To that end, a modified version of Sakai and Kikuchi (2008) Questionnaire of Demotivation of English Language Learners (DQELL) was administered to randomly selected 30 male EFL students and 30 females from third year Foreign Languages Department at Faculty of Arts and Humanities of Albaha University, KSA in the academic year 2021/2022. Results indicate that male students consider Learning contents and materials and Inadequate college facilities as their most EFL demotivating factors and the least ones were Teachers’ competence and teaching styles, Lack of intrinsic motivation and Test scores. On the other hand, female students consider Inadequate college facilities the most demotivating factor, while Learning contents and materials, Teachers’ competence and teaching styles and Test scores were their least demotivating ones. In addition, T-test results showed that there are statistically significant differences between male and female students on EFL demotivation factors Learning contents and materials and Teachers’ competence and teaching styles in favor of females. There are not significant differences between males and females on Inadequate college facilities, while there are significant differences between them on Lack of intrinsic motivation and Test scores in favor of female university students. Finally, statistical results were discussed and implications for ELT were suggested.
