Authors: TT Alemu
Published: August 2023

Mango (Mangiferaindica L) fruits were consumed for their pleasant taste and flavour. It rich sources of vitamins A, B and C. However, there is huge loss of the mango fruit during storage due to lack of temperature management and use of slow cooling rate. The objective of this study is therefore to investigate the effect of cooling rates on physical and chemical properties of mango fruits subjected to different cooling rates. The study was lied down with one factors randomized complete block design (RBCD) and replicated three times. Mango fruits were subjected to three different cooling rates (0.001, 0.019 and 0.087) through storage at different storage temperature (-1, 4 and -18°C) and evaluated in terms of physicochemical properties of the fruits during the storage. Data were analyzed by using Minitab software and the effect of cooling rate on all response variables measured was analyzed using Analysis of variance and the significance terms were accepted at 95% (p <0.05) confidence level. The result indicated that mango fruits subjected to different cooling rate exhibited significant change for all evaluated parameters. The mango fruits stored at highest cooling rates (0.087) preserves moisture contents from (70.57-64.45% ) and at lowest cooling rates, moisture reduced from (64.73-60.45%) pH increase (3.7-3.78) and Titratable acidity (TA) decrease (0.35-0.30 %) , total solid soluble (TSS) increase from (8.76-11.25 degree brix) weight loss increase (13.6-19.4%) and the ash content of mango fruits stored at highest cooling rates changed from (8.8-6.8%). This could be due to the fact that highest cooling rate (0.087) preserves physico-chemical properties. During this study because of some constraints, some parameters were not included. Therefore, based on the limitation of the work, further research is needed to study the effect of cooling rates on vitamin (A,C and B) and minerals and (protein, carbohydrates, fat), and beta-carotene of mango fruits which are not conducted in this research due to budget and time limitations, large scale cooling room needed. Generally, it was concluded that, highest loss of mango fruits occurred due to inappropriate storage temperature and highest cooling rates (0.087) preserve physico-chemical properties during storage periods.

Published: August 2023

This research was conducted at Borlaug Institute of South Asia (BISA) Pusa, Bihar to assess the losses in harvesting and threshing by manual methods for wheat and maize. 5 farmers from 15 identified villages were selected from Samastipur district of Bihar for assessing harvesting and threshing losses of wheat and maize crop. A total of 75 farmers were selected for this study from Kabargama Phulhara, Ajana, Gopalpur, Maniarpur, Rampura, Ladaura, Birsingpur, Kalyanpur, Akbarpur, Pratapur, Basudevpur, Dhruvgama, Tera, Mirjapur, Samastipur. A pre-procedure for loss assessment was used to record the details of the harvesting and threshing loss practices. It was observed that the total harvesting loss in all 15 villages were 1.65% and threshing loss 2.30% and maize 1.20%, respectively. Wheat Threshing Loss was found highest at 3.35% in Mirjapur village and the lowest at 1.18% in Rampura. Maize threshing loss was found to be highest in Pratapur village by 1.66% and lowest at 0.85% in Ladaura. The threshing loss was found less in Maize as compared to the harvesting and threshing loss of wheat and Maize due to the low loss, it is because of the long-stalked cubs of corn, in which there is no settling loss. The increase in losses was probably due to delays in harvesting due to unseasonal rains and storms, when the crop was ready for harvesting in some cases and less use of technologies at the agricultural level. There is a need for training farmers while harvesting and threshing of wheat and maize to reduce the loss of grain.

Published: August 2023

The present investigation was conducted at the Breeder Seed Production Unit, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, M.P., India during November to April, (Rabi season), 2021 to 2022 analyse grain yield and its attributing traits of wheat by correlation and path coefficient analysis. The twenty genotypes were in randomized complete block design with three replications. The results indicated that the biological yield per plant had highly significant correlation followed by harvest index with a moderate positive value and is significant with the grain yield per plant. Similarly the analysis of direct and indirect effects shows that the plant height, flag leaf length, flag leaf width, days to 50% flowering, grains per spike, biological yield per plant, and harvest index had positive direct effect on grain yield per plant. Hence it may be considered that traits namely, plant height, flag leaf length, flag leaf width, days to 50% flowering, grains per spike, biological yield per plant, and harvest index may be utilized for yield improvement breeding strategies in wheat. However, biological yield and harvest index will be given prime importance during selection of traits, due to their significant association and having a direct or indirect effect in crop yield improvement.

Exploring the Pedagogical Potential of Monolingual Corpora in Inverse Translation Training
Authors: Alshubaily Sara , BinSultan Nora
Published: August 2023

This article presents a comprehensive study that delves into the untapped potential of incorporating monolingual corpora as a strategic tool within translator training to enhance trainees’ proficiency in the challenging domain of inverse translation from Arabic to English. By shedding light on the pedagogical promise of monolingual corpora in inverse translation instruction, this research underscores the critical need to integrate this tool into translator training curricula, thereby amplifying the translation competencies of trainees. The central research inquiry is as follows: How does using a monolingual corpus enhance the performance of students engaged in inverse translation of collocations from Arabic to English within the context of political and media texts? The researchers focused on two groups of female students specializing in political and media translation at the College of Language Sciences, King Saud University. These groups, a control and an experimental one, were meticulously trained with different references—while the control group relied on conventional bilingual dictionaries, the experimental group employed monolingual corpora as their primary translation references—the assessment criterion centered on translating a newspaper text. The noteworthy outcome of this comparative analysis was that the experimental group consistently outperformed their counterparts in the control group by leveraging monolingual corpora. The findings from this research offer precise guidance to enhance the efficiency of translation training programs. Moreover, the study equips translators with essential skills and competencies and elevates the quality of translation training programs.
Comparing the Performance of Google Translate and SYSTRAN on Arabic Lexical Ambiguity
Authors: H Aldawsari Hamad Abdullah
Published: August 2023

Machine translation systems face many challenges when dealing with Arabic lexical ambiguity, which affects the quality and accuracy of their translations. This study investigates how two popular MT systems, Google Translate and SYSTRAN, handle three problematic linguistic features of the Arabic language: homonyms, heteronyms, and polysemes. A test suite was designed to include sentences that contain these features in different contexts and domains. The translations produced by the two MT systems were evaluated by four independent evaluators for intelligibility and accuracy using a four-point scale. Results showed that both MT systems struggled with the three chosen linguistic features, with average scores below 40%. Google Translate outperformed SYSTRAN in almost every sentence in the test suite. Both systems scored better in intelligibility than in accuracy. Heteronyms proved to be the most challenging for both MT systems due to the unique design of Arabic discretization, which is not yet recognized by translation systems. This study contributes to the field of machine translation by providing a comprehensive analysis of Arabic lexical ambiguity and its impact on MT quality, as well as suggesting possible ways to improve MT systems for Arabic-English translation.

Published: August 2023

This quantitative study aims at measuring the extent to which Saudi translation agencies use Computer-Assisted Translation Tools. It gives researchers and other people who look forward to working in Saudi translation marked a clear picture of the status of using Computer-Assisted Translation Tools. Two questions control the study: 1)to what extent are CAT tools used in Saudi translation agencies? 2) to what extent are Saudi translation agencies aware of the features of CAT tools? The study used a questionnaire distributed among 11 Saudi translation agencies for data collection. The data were analyzed by frequency distribution tables illustrating each response’s percentage. The results showed that there is still a lack of translation technology, including the use of CAT Tools, in Saudi translation agencies, even with the noticeable increase in adopting these tools. More than half of the participants show unawareness of these tools or their features. Therefore, they have negative expectations for their future. This study contributes to translation studies, highlighting the importance of integrating CAT tools into the Saudi translation market and university programs.

Translators’ primary responsibility is to faithfully convey the original message from the source text into the target language. This study’s initial observation revealed that many beginning translator students frequently represent texts word for word without first reading them. Therefore, insufficient translation procedures can lead to translation errors in student work. This study aims to analyze translation issues in academic essays written by students. The data for this study were gathered using the qualitative approach. Mathieu’s (2003) theory of translation concerns analyzing the linguistic and non-linguistic challenges that can be identified in the translations of students’ essays. The results reviewed that translation issues involved numerous linguistic aspects, such as grammar, vocabulary, rhetoric, and pragmatics. Moreover, culture as well.

Authors: NAVARRO ZAMORA LIZY
Published: August 2023

El presente trabajo científico comprende el tema emergente de la Inteligencia Artificial (IA) y el ciberperiodismo en la zona geopolítica de América Latina. El alcance del presente trabajo es descriptivo, transversal; se aplicó un cuestionario a 157 periodistas de Perú, Argentina, México, Colombia y Costa Rica. Se desarrolló un cuestionario de 15 preguntas que permitió conocer los ámbitos del conocimiento, uso y el reconocimiento de algunos ejemplos de la IA. Aún en los cibermedios más desarrollados existe un gran retraso en las IA, visibilizado con el escaso uso; por la reducida formación de los ciberperiodistas y por el no interés de los empresarios. Estos recursos de las IA pueden apoyar el desarrollo de cibermedios emergentes y disminuir la desinformación en el contexto latinoamericano

El Espacio Europeo de Educación Superior estableció un nuevo escenario para las relaciones Universidad-Empresa poniendo un énfasis especial en las prácticas externas. Así, éstas han ido ganando en importancia en los últimos años ya que permiten a los alumnos obtener una experiencia profesional real y una formación práctica donde aplicar los conocimientos teóricos adquiridos, así como establecer relaciones que pueden ser de ayuda en su incorporación al mercado laboral, dándose a conocer a las empresas del sector. Asimismo, las prácticas suponen para las empresas una interesante oportunidad de formar a estudiantes que pueden constituir una cantera de personal especializado para su contratación posterior. El presente estudio muestra el análisis de los resultados obtenidos en el primer Plan de Tutorización de Prácticas Extracurriculares realizadas durante el curso académico 2020/2021, que se implanta en la Universidad de Málaga con el objetivo de fomentar y cuidar las prácticas externas en las empresas para crear nuevos profesionales capaces de transformar las empresas en más competitivas e innovadoras.

OBJECTIVE

To define cyclic changes in anti-Müllerian hormone (AMH), inhibin-B, and progesterone concentrations and establish statistically valid, population-based clinical reference ranges in queens.

ANIMALS

Cyclic queens (fertile, n = 6; infertile, 6) from an institutional breeding colony were blood sampled longitudinally, each for over 2 months, between November 2021 and February 2022, and residual serum samples from intact (n = 205) and ovariohysterectomized (49) queens from clinical submissions were used to establish reference ranges for intact and spayed females.

METHODS

AMH and inhibin-B were measured using commercially available ELISAs, progesterone was measured using an in-house ELISA, and 90% CIs were calculated from these data.

RESULTS

AMH and inhibin-B fluctuated in a highly correlated, cyclic pattern in 3 queens that did not ovulate immediately, whereas AMH declined as progesterone increased, indicative of ovulation, which occurred spontaneously early in the sampling period in 3 others; statistically valid reference ranges were established in intact and ovariohysterectomized females.

CLINICAL RELEVANCE

Cyclic changes in hormone profiles were defined, providing relevant context for interpreting results in cases seeking to determine gonadal status (presence or absence of gonadal tissue) on the basis of established, population-based reference ranges reported here for cats for the first time.
The Effect of Holding Time on Stress Relief Annealing Process to Hardness of Carbon Steel SA.106 Grade B After Welding

Stress relief annealing (SRA) is a process of releasing residual stresses contained in the material due to the welding process. The need for SRA is due to heterogeneous changes in the microstructure when the material is exposed to the heat of welding so that it will cause the mechanical properties of the material to change. One of the mechanical properties that experience significant changes is hardness (hardness value) because it can experience an increase. Therefore it is necessary to decrease the hardness value through a heat treatment SRA that takes into account the appropriate holding time. The purpose of this study was to determine the effect of holding time variations on the value of the welding material hardness for the carbon steel case SA.106 Gr.B. During this time after welding SA106 material specifically under 19 mm thickness is not heat treatment after welding even though the welding effect will change the properties of this material, so it is necessary to heat treatment with certain holding time variations to determine its effect on the mechanical properties of the material. The welding process uses SMAW with E7018 electrodes. Specimen heating is carried out in a heating oven to a constant temperature of 650oC with variations in the heating time of 15 minutes, 30 minutes, and 45 minutes. Furthermore, hardness testing is done by testing the base metal area, heat affect zone, and weldment. The results that SRA greatly influenced the hardness value of a welded material, based on testing the highest hardness value in the SRA heat treatment was obtained at a holding time of 45 minutes with a hardness value on the base metal of 67 HRC (BM), HAZ area of 65.25 HRC, and weldment area of 64.42 HRC. But at the holding time for 45 minutes, the value of material hardness tends to be more uniform compared to other variables.

Purpose: The condition of competition between coal mining contractors causes the company leaders to manage the company and try as optimally as possible to get a competitive advantage compared to other similar companies. This study discusses the relationship of Competitive Advantage built from Market Orientation variables, HR Competence, and Knowledge Management to the performance of coal mining contractors in a comprehensive manner. It explains the transformation process of Company Performance to Competitive Advantage.   Research implications: A research population is a number of 37 Coal mining contractors in Indonesia, including employees who are directly involved in strategic decision making in the company, namely the Project Head, Head Office Manager, and Director as respondents.  Based on these data, Smart PLS 4 software processes structural parameter estimates according to the relational model described in the study's conceptual framework.   Results and conclusion: The results showed that Market Orientation, Knowledge Management and Company Performance have a significant effect on Competitive Advantage, Quality of Human Resources, Market Orientation and Knowledge Management also has a direct effect on Company Performance, but Quality of Human Resources has no significant effect on Competitive Advantage. While the Company's Performance is a Full Mediation of the Quality of Human Resources on Competitive Advantage.   Originality/value: This research contributes to the development of RBV theory, especially the study of company performance on competitive advantage in a resource-based view perspective through market orientation, HR competence, knowledge management, and the practice of applying SECI knowledge to this research object, which is proven to be able to increase competitive advantage.   Theoretical reference: The originality of the theoretical model in this study contributes to the development of the RBV theory, the implementation of the concept of Competitive Advantage regarding the integration of internal key resources between intangible and capability aspects of coal mining contractors.
