Authors: Mosquera Castro Estefanía
Published: March 2021

Neste traballo analízanse as características da comunicación electrónica, un novo medio de interacción favorecido polo avanzo da Enxeñaría Informática e das Tecnoloxías da Información e da Comunicación que permite ás persoas intercambiaren información de modo sincrónico ou asincrónico con independencia da súa localización física. En concreto, focaremos a nosa atención nas propiedades discursivas destes novos sistemas, que partillan trazos coa escrita e coa oralidade, mais tamén presentan elementos idiosincráticos (comunicación in absentia, copresenza virtual, permanencia textual etc.), resultado das características do medio que os alberga. Estes datos permiten afirmarmos que estamos perante unha nova modalidade comunicativa, independente a respecto da oralidade e da escrita e específica do medio dixital.

Published: March 2021

COVID-19 pandemic disease gained major attention among scientists due to its high mortality/ infectiousness rate. Moreover, the analysis of this disease requires much attention by the Government to take precautions and construct strategies. This study aims to develop a new nonlinear model for COVID-19. The main focus is the time when the number of daily infected individuals has begun to increase constantly. To this end, the time series from 1 August 2020 to 22 September 2020 is conducted. Moreover, the proposed model takes into account the disease characteristics. After the model parameters are obtained by detailed mathematical analysis by the trained data, the model is validated by the test/evaluation data set. The results and simulations show that the proposed model has a perfect match with the raw data. Furthermore, the calculated standard errors when compared by the population of Turkey are evidence of how well the model fits the raw data. This study is important not only because it achieves good results but also because it is the first nonlinear regression model including its mathematical analysis for the COVID-19 pandemic.

Published: March 2021

Research aims: The objective of this research is to analyze the effect of Gross Domestic Product, exchange rate, and distance on the meat import performance of ASEAN countries both partially and simultaneously.Design/Methodology/Approach: Purposive sampling method was adopted to determine the research sample. The data used were the annual secondary data of ASEAN countries in the period of 2012-2018, collected from trademap.org, World Bank, and macmap.org. Multiple Linear Regression was employed to analyze the data.Research findings: The regression analysis results showed that GDP and exchange rate did not affect meat import performance. Meanwhile, distance had a partially significant negative effect on meat import. However, GDP, exchange rate, and distance had a significant effect on meat imports simultaneously.Theoretical contribution: Previous researchers have used economic distance in their study to see its impact on imports. Nevertheless, there has not been much research done using geographical distance as an antecedent variable. The distant market has to incur large-fixed costs, which can only be supported if the export value is large. The negative impact of distance on imported meat must be taken seriously. AANZFTA supposedly gives a contribution to the member countries thoroughly to export goods and services. It is to increase per capita income so that it can be used to improve the transportation system.Implication policy: ASEAN officials are suggested to encourage the member countries to provide better transportation facilities to eliminate geographical distance barriers and further support SMEs and other business actors' engagement. Due to the limitation of this research, it is suggested that further research should consider using other commodities to measure the import performance.
The Indirect Impact of Busy Directors on the Relationship of Family Structure and Cash Flow Sensitivity of Cash (Empirical Research in Indonesia’s Manufacturing Sector 2013-2017)
Authors: Santoso Wahyu , Utama Cynthia Afriani
Published: March 2021

Research aims: This research aimed to determine the impact of family structure on the cash flow sensitivity of cash (CFSC) in the manufacturing sector. It also investigates the indirect impact of busy directors as a moderating effect.Design/Methodology/Approach: Based on a sample of Indonesia’s manufacturing companies from 2013 to 2017, the researcher uses GLS regression models on this panel data calculated with robustness fit test at the firm’s level.Research findings: It indicated that family structure has a impact positively on cash flow sensitivity of cash and statistically significant. Meanwhile, the indirect impact of busy directors  found to have a impact negatively and weakened on the relationship of family structure and CFSC, it also indiciated that quality of busy directors is an tool of corporate governance that is effectively to monitor of every family firm’s decisions.Theoretical contribution: This article enriches previous literature by justifying the impact of busy directors on the relation between every each of family’s firm decision and CFSC. Furthermore, it showed us a metric for agency problems that is the sensitivity of cash to corporate cash flows.Implication policy: Based on POJK regulations, the context of busy directors in this research refers to the roles and duties of the Board of Commissioners (BOC) which concurrently hold positions for other public companies.Research Limitation/Implication: The implications suggest that almost most of Indonesian family corporation are tend to expropriate minority by extracting rents through coporate cash flow sensitivity of cash behavior.

Background: Severe dengue has become a leading cause of hospitalization and death among children and adults in most Asian countries. WHO stated that the death rate of children with severe dengue who required hospitalization is about 2.5%? It is one of the principal epidemic diseases in Myanmar. Moreover, the highest numbers of dengue cases and deaths was between age 5 and 9 years followed by between age 2 and 4 years.Methods: A cross-sectional study among 168 preschool teachers by surveying with semi-structured questionnaire.Results: The mean age was 29.36±9.04 years. Nearly 70% of them were graduated. Only 30.95% had high level of knowledge, 48.81% had positive attitude and 44.64% had good preventive practice level. There were no significant associations between socio-demographic characteristics and levels of knowledge, attitude, and preventive practice with the exception between education and levels of knowledge (p=0.027). Between knowledge and attitude, there was a significant association (p=0.005). However, levels of prevention practice had no significant association with levels of knowledge and attitude.Conclusions: Despite their high education, preventive practice still needs to be promoted.

Background: The goal of this questionnaire is to understand the social implications and the knowledge urban populations has about COVID 19, and are people are taking proper precautions against the disease.Methods: Since there is no proven validated vaccine for prevention of COVID 19 to date, isolation of high-risk individuals and social distancing is the only solution to limit the spread. Since the government of India imposed the national lockdown on 22 March. A cross-sectional questionnaire-based study was carried out by dispensing the questionnaire to individuals through online mode. A total of 633 responses were collected from individuals by a pre-designed. In our study we studied the knowledge of the Indian population about COVID 19. 64.8 % reported that they are well versed in the details of the pandemic COVID 19. More than 94 % of individuals stated that they are properly prepared and are taking proper precautions. Moreover approximately 95% of the population feels the seriousness about COVID 19 increased after lockdown. The majority of people are aware of the measures to be taken for avoiding transmission of COVID 19 infection. But some people are still not aware of the precautions to be taken to avoid the spread of the disorder.Conclusions: Along with isolation and social distancing, creating awareness about the disease by educating the people about COVID 19 is also important. Physical health taking care of the mental health of individuals is equally important.

Background: The seroprevalence studies are conducted with the aim of estimating the extent of SARS CoV2 infection in any community. A cross sectional population based study was conducted in Srinagar district of Kashmir, India so as to provide relevant information on the proportion of people who have experienced a recent or past infection.Methods: An estimated sample size of 2400 was calculated based on anticipated seroprevalence of 20% and an absolute error of 2.5%. 20 clusters were selected using 2 stage cluster sampling. A set of questions on a mobile based application i.e Epicollect 5 was used to collect information on various variables and 3-5 ml of venous blood was taken for Ig G antibody testing. Chemiluminiscent Microparticle Immunoassay (CMIA) procedure using fully automated analyser by Abbott with sensitivity of 100% and specificity of 99.6% was used to detect IgG antibodies against SARS COVID-2.Results: 2480 eligible individuals participated in the study. The overall seroprevalence of Ig G antibodies against SARS-CoV 2 in the current study was 40.6% (95% CI 38.7-42.6), with seroprevalence being significantly higher among females (44.7% as compared to 37.5%).  Age standardized seroprevalence revealed that seroprevalence increased with the increasing age.Conclusions: The findings of Seroprevalence study may fail to reveal the true picture of covid-19 infection as there were certain participants who were positive for COVID on RTPCR but were IgG negative. Thus, the individual variation of immune response to the virus, role of mucosal Ig A antibodies and T cell mediated immunity cannot be ruled out.

Authors: Jose Manu , Fenn Jessy
Published: March 2021

Background: In mid-August 2018, Kerala witnessed the worst floods since 1924 due to abnormally high rainfall and simultaneous release of water from its dams, resulting in extreme flooding in 13 of the 14 districts in the State. The large-scale flooding impacted millions of people and caused nearly 400 deaths as well as immense damage to property. This was followed by flooding yet again in August 2019, thereby triggering further damage. Farmers whose crops got completely wiped out were one group that were severely affected. This study investigated the presence of post-traumatic stress disorder (PTSD) in farmers and also checked the relationship between PTSD and resilience. Methods: The sample consisted of 100 farmers from the Alappuzha and Pattanamtitta districts of Kerala which were severely affected by the flood. Data was collected through the PTSD-8, Brief Resilience Scale (BRS) along with sociodemographic data and flood related information.Results: 74% of the farmers scored high on the test indicating the presence of PTSD. The farmers of interior Pathanamthitta had significantly higher incidence (84%) of PTSD than coastal Alappuzha farmers (66%). The level of damage due to the flood did not have significant correlation with PTSD.  There was significant negative correlation between PTSD and resilience (r=-0.64).Conclusions: There was high incidence of PTSD among the farmers of central Kerala post the 2018 and 2019 floods and it was higher in interior Pathanamthitta than in coastal Alappuzha which is more used to the vagaries of the waters. Resilience helps to combat PTSD.

Authors: Kaur Amandeep , Ghosh Tandra , Ahamed Farhad
Published: March 2021

Media finds doctors as a soft target for all sorts of healthcare system failure. The hostile media reporting has demonized the medical profession and has forced doctors to adopt a more reserved attitude. The present study focuses on assessing the effect of media on patient management by the doctors who had not faced violence at the workplace. It was observed that as a consequence of unfavorable media reporting, prescribing of investigations, and referral and consultation liaison increased, whereas, handling of complicated cases by the doctors decreased. Therefore, even the doctors who have not faced any workplace violence are influenced by news of workplace violence against doctors and are adopting safer strategies in the management of patients.

Published: March 2021

La comunidad zooplanctónica es muy diversa en la zona tropical y tiene un papel importante en el flujo de energía de la red trófica, además, su alta tasa de crecimiento le permite responder rápidamente a cambios ambientales en la columna de agua. En este estudio se identificaron hasta el mínimo nivel taxonómico posible los rotíferos, copépodos y branquiópodos en un humedal de zonas bajas del departamento del Tolima, y se estimó su abundancia y las posibles relaciones con las variables fisicoquímicas. Se hicieron muestreos mensuales puntuales utilizando una red de filtrado y en cada época de muestreo se tomaron muestras de agua para el análisis de las variables fisicoquímicas y bacteriológicas. El conteo y la identificación se hicieron con una cámara de sedimentación SedgwickRafter. La comunidad estaba compuesta por 30 géneros, 23 de ellos correspondientes a rotíferos, seguidos de los copépodos con cuatro y los cladóceros con tres. La densidad de la comunidad podría estar condicionada por las precipitaciones y las macrófitas. A nivel fisicoquímico, la alcalinidad fue la única variable con un valor significativo en los muestreos. Por último, los rotíferos presentaron una mayor diversidad, abundancia y riqueza en todos los muestreos debido a su adaptabilidad y dominancia en la zona tropical.

Authors: Mutani Guglielmina , Todeschi Valeria
Published: March 2021

Green urban infrastructures have a significant impact on urban climate mitigation, on indoor and outdoor thermal comfort and on energy performance of buildings. In this paper, outdoor thermal comfort conditions and energy saving for space heating and cooling were investigated before and after the use of roof-integrated green technologies. Existing urban energy and climate models and tools were applied to an urban area located in a Turin (Italy). CitySim, ENVI-met and SOLWEIG tools and a GIS-based model were used to evaluate the mean radiant temperature and the thermal comfort of outdoor spaces before and after the use of vegetated roofs and green surfaces such as the predicted mean vote (PMV), the physiological equivalent temperature (PET) and the universal thermal climate index (UTCI). A GIS-based engineering model and CitySim tool were used to evaluate the energy saving and energy independence index for space heating and cooling after the use of green roofs and solar technologies. According to the shape and the suitability of rooftop elaborated with GIS tools, some roofs were identified as potential green roofs other as potential solar roofs for installing solar thermal collectors and photovoltaic panels. According to the results it is possible to confirm that the use of green roofs and urban greenery can decrease the mean radiant temperature until about 10℃ during summer season, improving outdoor thermal comfort conditions and energy savings with a reduction of 12% for space cooling energy consumption.
Sustainable Agriculture, Food Production and Poverty Lessening in Nigeria
Authors: Omodero Cordelia Onyinyechi
Published: March 2021

The challenge of persistent poverty and food insecurity in Nigeria has been an issue of concern. The government’s effort to alleviate poverty in Nigeria through agriculture appears ineffective because most poor people are rural dwellers and are coincidentally the farmers. They seem not to be benefiting from the government interventions to support farming due to corruption and other unquantifiable factors. This study investigates the impact of agricultural output and food production on poverty decrease in Nigeria. The data used in this study span from 2009 to 2019. Relevant diagnostic tests and regression analysis are performed to obtain the empirical evidence highlighted in this paper. Thus, the findings reveal that the Food Production Index significantly and positively impacts poverty reduction, while Agricultural Output has an immaterial negative effect on poverty decrease. The study concludes that poverty alleviation in Nigeria and food security will depend on government’s full involvement in agriculture and improvement on its agricultural budget. Accordingly, the provision of necessary facilities to boost agriculture have been recommended. The facilities include modern farming equipment, sufficient power supply, credit facility, storage facility, and large markets.
Economic Planning of the Operation of PV-Connected Distribution Network Using a Probabilistic Model for Extending the Network Lifetime
Authors: Majid Amir
Published: March 2021

The power sharing of PV sets with battery banks in a low voltage distribution network, is optimized with the aim of extending network lifetime. The network lifetime is analyzed using a probabilistic model, in which each PV-battery set has a certain failure probability of supplying power to any load demand center. This probability is assumed to be of normal distribution, that is related to other factors such as power rating, coverage availability, and battery DoD. To extend network lifetime, redundancies in power sharing are removed by activating different groups of PV sets at different times, with durations depending on their joint Gaussian probabilities in supplying the load demands. The contribution of each PV-battery set, is estimated in an intuitive method according to the evaluated probabilities, in which the network is converted into source nodes and load nodes distributed as an ad hoc network, with formulated Gaussian probabilities. An economic load dispatch is then evaluated among the selected PV sets of probabilities higher than a predefined threshold value, to optimize power sharing of the load. A case study of several PV-battery sets supplying several distributed loads, is analyzed and simulated, with formulated joint probabilities. It is found that lifetime is extended by 190% for three PV sets supplying two load centers.

Authors: Mehta Ridhima
Published: March 2021

The exemplary design of green buildings incorporates multiple correlated parameters that should be optimally selected and updated to ensure effective energy management and sustainable impact of building architecture on the ecosystem. In this paper, the adaptive modeling and development of such sustainable buildings with several unpredictable and qualitative attributes is implemented with multiple-input multiple-output (MIMO) fuzzy control system. The outputs of the proposed fuzzy corroborated sustainable building paradigm comprise of specific characteristics employed for assessing the optimal performance, viz. energy efficiency, user satisfaction, resources optimization, and environment quality. These diverse system criteria measured using the proposed fuzzy optimization model are plotted against their actual theoretical values for each data case. Furthermore, the sample dataset for the proposed sustainable building model is validated through simulation results in terms of mean absolute error and logarithmic quotient error in the estimation of various fuzzy output variables evolving with the dataset size.

In the current study, this way was adopted numerically in order to optimize the performance of a HEC through the use of extended solid sections in the form of 'W' (W-baffles: WBs). All limit conditions of the channel have been defined, with all the thermo-physical properties of the HTF (heat transfer fluid) used. The FVM (Finite-Volume-Method) has been adopted with some necessary numerical schemes in order to give the numerical solution, which allows us to visualize dynamically the flow filed and to deduce all the energetic characteristics contained by this HE. Dynamically, the HTF flow velocity at the HEC outlet section reached about 1.812 m/s, in the case of the lowest Re value. While, it passed 4.8 m/s in the case of the largest value of the same variable, i.e. 1.726 to 4.648 times better than the Uin within the limits of Re numbers used. Thermally, areas with very hight TGs (temperature gradients) were observed near the top deflector’s sides, which reflects the effect of the W-baffles. This highlights the importance of the adopted obstacles in changing characteristics of the HEC to the best.

Published: March 2021

The performance of the Flat Plate Collector (FPC) and Evacuated Tube Collector (ETC) for domestic hot water applications under Jordan climate conditions was theoretically investigated using TRNSYS software. The presented simulation model can provide a long-term evaluation of system performance at different weather conditions. This simulation was carried out during 24 hours in 21 June, is considered as a hot climate and 21 January is considered as a cold climate; under the meteorological conditions of both Irbid and Aqaba cities in Jordan. The inlet water temperature of the first collector, collector area, water flow rate and tilt angle were considered 15℃, 2.04 m2, 0.0139 kg/s and 45 degrees respectively. The outlet temperature of each collector was considered as the inlet of the previous collector. Three collectors in series were applied to increase the output temperature up to 90-100℃. The results showed that TE increased with the decrease in the inlet temperature, which means the useful energy gain (Qu) of the first collector is greater than the 2nd and the 3rdcollector. The useful energy gain (Qu) of ETC is greater than of FPC, and the useful energy gain (Qu) of cold climate is less than hot climate. The output temperature of ETCs is greater than that of FPCs for Irbid city in cold and hot climate. Furthermore, for Aqaba in cold climate and in hot climate the outlet temperature of ETCs is higher than FPCs. Additionally, the daily thermal performance of the ETCs is significantly better than the FPCs in cold climate. Meanwhile, thermal performance of both collectors are close in a hot climate.

Published: March 2021

Imatinib has an important place as an adjuvant therapy as well as in the treatment of metastatic disease caused by gastrointestinal stromal tumor (GIST), which is one of the common mesenchymal tumors of the gastrointestinal tract. Imatinib is a tyrosine kinase inhibitor and is generally well tolerated. However, it can cause some serious adverse effects. The most common of these are edema on the face and legs, headache, fatigue, nausea, vomiting, and rash on the skin. The most serious side effects, albeit less common, are gastrointestinal or intraabdominal bleeding. However, thrombotic events such as sigmoid sinus thrombosis and splenic infarction are extremely rare. The current report presents a patient with GIST who is treated with imatinib 400 mg/day. The patient presented with edema on the face and headache in the second month of imatinib therapy, after which she was diagnosed with sigmoid sinus thrombosis. The patient who presented with abdominal pain approximately three months later developed splenic infarction. She was administered acetylsalicylic acid, supplemental oxygen (O2) in the first episode of thrombosis, and imatinib therapy was discontinued. The patient's complaints and thrombus regressed, after which imatinib therapy was resumed. She was administered intravenous hydration, supplemental oxygen, analgesics, and imatinib therapy was discontinued after the patient sustained splenic infarction. After resolution of sigmoid sinus thrombosis and the regression of splenic infarction area, the patient was switched to sunitinib therapy. She is attending routine control visits. Sigmoid sinus thrombosis and splenic infarction should be kept in mind as a rare cause of headache and abdominal pain in patients treated with imatinib, and detailed neurological and gastrointestinal evaluation should be performed.

Entrepreneurial Leadership Impact on Job security and Psychological Well-being during the COVID-19 Pandemic: A conceptual review
Authors: Guberina Tajana , Min Wang Ai
Published: March 2021

Studies dealing with the emergent coronavirus pandemic provide the multidisciplinary response to psychological, social, economic, policy and management challenges. The current paper identifies the key factors conducive to the psychological well-being of employees during the COVID-19 Pandemic. A conceptual review suggests relationships between entrepreneurial leadership, job security, fear of COVID-19 and psychological well-being. We posit that entrepreneurial leadership results in leads to higher job security and increased Psychological well-being. Furthermore, Job insecurity leads to worse psychological well-being and mediates the relationship between Entrepreneurial leadership and Psychological well-being. Fear of COVID-19 moderates the relationship between entrepreneurial leadership and job insecurity. When the job insecurity under the threat of COVID-19 intensifies, entrepreneurial leaders act to strengthen organizational commitment and provide positive psychological empowerment.
Las antologías poéticas de mujeres en los siglos XX y XXI: retrospectiva y comentario crítico
Authors: Patrón Sánchez Marina
Published: March 2021

Las antologías poéticas formadas en exclusiva por mujeres comenzaron a publicarse en el siglo XX como una forma de suplir el vacío que había en la historia literaria de España, a la par que se buscaba dar una mayor visibilidad a la obra poética de las escritoras. Esta práctica, que se ha extendido hasta el siglo XXI, es un arma de doble filo, debido a que por un lado ofrece un espacio para las poetas; pero, por el otro, el tratamiento que a veces reciben es injusto o insuficiente. Este trabajo realiza una retrospectiva sobre las más relevantes antologías de poesía escrita por mujeres, analizando su contenido, sus prólogos y el tratamiento que reciben las creadoras en ellas
El adulterio: sociedad y literatura en el siglo XIX. La Regenta (1884–1885) y El primo Basilio (1878)
Authors: Nastasescu Diana
Published: March 2021

En este artículo se hace una comparación entre las dos novelas cum-bre del siglo XIX que tratan el tema del adulterio femenino en España y Portugal, La Regenta (1884–1885) de Leopoldo Alas Clarín, y El primo Basilio (1878) de Eça de Queirós. De este modo, se pretende analizar detalladamente las causas, los momentos y las consecuencias del adulterio para cada uno de los implicados en el mismo. Se observa el camino recorrido por Ana Ozores y Luisa de Brito Carvalho hacia el fatal desenlace, la diferencia entre sus matrimonios, la insistencia romántica del pretendiente de cada una de ellas y sus inclinaciones místicas o la inexistencia de estas.
Literatura escrita “desde la infelicidad”: sobre la narrativa de Horacio Castellanos Moya
Authors: Sadowska Natalia
Published: March 2021

Horacio Castellanos Moya es uno de los autores más interesantes y originales que en las últimas dos décadas han marcado su presencia en el campo de la narrativa hispanoamericana. En una de las entrevistas concedidas, el autor salvadoreño afirmó que escribe “desde la infelicidad”: producto de la experiencia del terror de la guerra civil, de la desilusión con la especie humana y del sentimiento de desarraigo. Las experiencias mencionadas han dejado huella en su narrativa, influyendo en la temática de sus textos y en el lenguaje que emplea. Por tanto, el objetivo del presente trabajo consiste en acercarse al peculiar estilo de la prosa de Castellanos Moya –perteneciente a la llamada narrativa post-testimonial–en la que los sentimientos como la rabia, la nostalgia o la indignación son expresados mediante un vasto abanico de herramientas literarias.

Background: The variety of indigenous duck germplasm contribute maximum to the poultry industry in India, besides chicken population. In southern part of India, the available duck genetic resource, particularly Arni ducks (comprises of Sanyasi and Keeri ducks) of Tamil Nadu, has its own characteristics with innate potentiality of higher productivity without any input system of management. Genetic characterization and diversity of indigenous duck genetic resources has not been properly studied. In the present study, the genetic diversity of Arni ducks with other indigenous and exotic duck germplasm were analysed with microsatellite markers. Methods: Genomic DNA was isolated from the blood samples of six duck populations. Molecular characterization was carried out with duck specific FAO recommended microsatellite markers. The genotyping of ducks was done based on the size of 4324 PCR amplicons of 23 microsatellite loci, which were subjected to capillary electrophoresis using automatic sequencer. Result: A total of 222 alleles in six duck populations across 23 microsatellite loci with a mean of 9.65±0.95 alleles were found. Kuttanad duck variety had the highest number of alleles (139) followed by Sanyasi (136), Keeri (129), Muscovy (118), Assam (91) and White Pekin (78) ducks. The mean observed number of alleles was 6.04±0.59, 5.91±0.76, 5.61±3.17, 5.13±0.44, 3.96±0.76 and 3.39±0.40 in Kuttanad, Sanyasi, Keeri, Muscovy, Assam and White Pekin ducks respectively. The overall mean polymorphism information content (PIC) values among the six duck populations was 0.6269. In most of the duck populations, the mean PIC value was more than 0.5 except in Assam (0.4815) and White Pekin (0.3725) ducks. The observed heterozygosity was the highest in Keeri ducks (0.5217) and lowest in White Pekin ducks (0.2766), while, the mean expected heterozygosity was the highest in Sanyasi (0.5628) and lowest in White Pekin (0.4038) ducks. The variations in the observed and expected number of alleles, differences in PIC of various microsatellite loci might be attributed to the genetic variability of the duck populations, number and type of microsatellite primers utilised for analysis and the genetic diversity of the duck breeds under study. Higher FST value indicates the substantial degree of breed differentiation among the studied duck populations.

Background: Faba beans (Vicia faba L.) are important grain legumes but, as with many crops, these are also susceptible to water deficit. The aim of this study was to evaluate the yield components of twenty faba bean genotypes grown under water deficit. Methods: Three water treatments were applied, 25%, 50% and 100% of field capacity. A split-plot arrangement in a randomized complete block design with three replicates was used. Result: The faba genotypes Gazira2, Kamline, L4, Cairo7 and Giza402 reached flowering earlier than other genotypes through stress-escape mechanisms. Genotypes L4, Gazira1, Kamline, X.735 and Gazira2 had the highest seed yield under water-deficit conditions. Genotypes L4, X.735, 989/309/95, Kamline and Gazira1 exhibited the highest levels of biological yield. Finally, the genotypes Kamline and L.4 had higher yields and yield components under water-deficit stress. Consequently, they should be considered for use in breeding programs aimed at developing new cultivars that are better adapted to harsh environmental conditions.
