Arab Diaspora online media in Sweden
Authors: Ezz El DIn Mahitab
Published: September 2020

With the increase in migration to the Western countries, social media became the alternative space for Arab diaspora to meet and bring in the issues of their concern. It is also a platform where one can examine the identities of migrants. In this article I analyze the comments in one of the most popular Arab diaspora platforms in Sweden where I identify migrant identity and aspects of integration as well. Combining a quantitative and a qualitative approach the study results show an internal conflict as well as two types of identities, internal and external. The identities are found in themes discussing racialization, counter racialization, citizenship and foreignness, Belongingness/Swedishness and political involvement.
Blockchain in education: Opportunities, applications, and challenges
Authors: Steiu Mara-Florina
Published: September 2020

This paper discusses the opportunities and challenges of applying blockchain technologies in the education sector. The key blockchain-in-education applications discussed are the digitalization and decentralization of educational certifications and the enhancement and motivation for lifelong learning. Some of the key challenges explored are data protection laws such as the General Data Protection Regulation and the California Consumer Protection Act, which pose impediments for application developers and scalability challenges that arise because of slow-speed blockchain transactions and the Scaling Trilemma. Additionally, market adoption and innovation challenges highlight that blockchain-in-education is a relatively immature innovation that governance bodies within educational institutions often disregard or perceive cautiously.
“Grabbism” and Untranslatability: Reinterpreting Lu Xun's Position as a Translator
Authors: Xie Haiyan
Published: September 2020

Lu Xun's translation discourse and his concept of “grabbism” (拿来主义 nalai zhuyi) are mutually constructed in a historical and evolutionary process. This article investigates how two different notions of “untranslatability” embedded in the discourse of Lu Xun's translation interact with his constantly rectified idea of “grabbism.” Lu Xun's translation process is replete with tensions and contradictions resonating with his simultaneous aspiration to and resistance against Western modernity. These tensions and contradictions are reflections of his self-contradiction between the collective responsibility of saving the nation by embracing Western modernity and a kind of unconscious reclamation of himself as a man of letters whose roots in Chinese tradition were less pronounced. Lu Xun's translation practice along with his “grabbism” provides us an alternative perspective to understand the politics of translation beyond English contexts and sheds light on our reconceptualizing the nature of translation.
Surface Modification Techniques to Enhance Osseointegration of Spinal Implants
Authors: Possley Daniel , Baker Erin , Baker Kevin , Khalil Jad G.
Published: August 2020

Biomechanical function, specifically implantation technique and immediate surgical fixation, of orthopaedic implants is the primary consideration during the development of orthopaedic implants. Biologic and material characteristics are additional factors to include in the design process because of the direct impact on short- and long-term implant performance. The body's initial interaction with implant materials can affect protein- and cell-based function, thereby either promoting or impeding osseointegration. An understanding and inclusion of the biologic response, material surface morphology, and material surface chemistry in implant design is crucial because these factors ultimately determine implant function and patient outcomes. Highlighting the biologic- and material-related advantages and inadequacies of current and potential implant materials as well as applications may guide further research and development of implant materials and designs.

Ants Can Acquire Multiple Symbolisms
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: September 2020

The workers of the ant Myrmica sabuleti were previously shown to be able to associate a given amount to its corresponding symbol, one symbol at a time. It was here examined if they can simultaneously learn to associate the amount 1 with a corresponding symbol, the amount 2 with another symbol, the amount 3 with a third symbol, and the amount 4 with a fourth symbol, the cue to avoid being the amount 5. Thanks to operant conditioning during 156 hours and twelve successive testing experiments, it was shown that the ants can effectively memorize, in the course of a same time period, the association between the amounts 1, 2, 3, and 4 and their respective symbols. A distance effect was observed for the learning of the amounts 1 to 4 versus 5, but not for the learning of their four corresponding symbols.
Ants Can Add Up Using Learned Numeric Symbols
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: September 2020

The workers of the ant Myrmica sabuleti have been shown to be able to add numbers of elements after having seen them simultaneously, side by side, during training, and to be able to acquire single as well as multiple symbolism. It was here examined if these ants could make additions using learned symbols. In fact, after having learned the required symbols during a first conditioning, the ants could, thanks to a second conditioning, carry out operations 1 + 1, 1 + 2, 2 + 2 and 3 + 1 by using the quantities of elements presented as well as their corresponding symbols. This ability results from the ants’ learning of the correspondence between symbols and numbers of elements by an operative conditioning, and from their ability to add up two quantities viewed simultaneously. A comparison of the ants’ score when adding elements and when adding their corresponding symbols suggests that the use of symbolism may represent some facility for the execution of simple arithmetic operations, as is the case in higher animal species.
The Weakening of the Hegemon and the Future of the Liberal International Order
Authors: Lisewski Mikolaj
Published: August 2020

The hereby paper presents a theoretical approach to the U.S.–China geopolitical rivalry as the process of dispersion of power from the hegemon to the challenger [Allison] that may toward, through the sphere of influence fragmentation processes, to the polycentricity of the international relations system. In this work the author presents a new theoretical approach to the U.S.–China political rivalry understood as a key element of a process of changing the model of the global hegemonic leadership, shaped most fully since 1991. The paper presents the concept of two theoretical levels – the rational strategy and the political vibrancy – which are a necessary context for identifying the nature of given decision-making processes of the main subjects of contemporary international relations. Thus, through the abovementioned concept the sino-american relations are explained within the methods that are being used by states with particular emphasis on analyzing the operations of the People's Republic of China. Furthermore, the author reasons why China is withdrawing from the use of soft power – understood in the terms of J. S. Nye’s – and why it primarily uses the linking power and sharp power [Walker, Ludwig]. The article ends with a summary in which author, based on the information presented, tries to answer the question – why the liberal international order remains uncertain (or is about to fail).
Protection of Personal Non-Property Rights in the Field of Information Communications: A Comparative Approach
Authors: Formaniuk Viktoriia , Kanienberh-Sandul Oksana , Palii Oksana , Borysova Anastasiia , Manuilova Anna
Published: August 2020

The issues which arise in connection with the use of information technologies are analysed in the paper. The attention is focused on the protection of non-property rights, such as honour, dignity, business reputation, violated on the Internet. It is noted that today there is a significant increase in the volume of legal regulation in this area. Nevertheless, there are still significant gaps in the protection of human rights, violated on the Internet. The current level of development of these processes objectively requires the creation of effective mechanisms and means to protect human rights and freedoms, including personal non-property rights. The existing ways of protection of persons on the Internet, such as judicial protection and self-defense are compared in the paper, there advantages and drawbacks are revealed. The types of violations of non-property rights of persons on the Internet are investigated. The specific attention is paid to cyberbullying. Some issues typical for communication on the Internet, such as difficulties in identifying where exactly the offence was committed and which court the claim should be addressed as well as the identification of the offender are revealed. Some shortcomings in the legal regulation of protection of persons on the Internet and ways to eliminate them are analyzed.
The Concept of Culpability in Criminal Law and AI Systems
Authors: Dremliuga Roman , Prisekina Natalia
Published: August 2020

This article focuses on the problems of the application of AI as a tool of crime from the perspective of the norms and principles of Criminal law. The article discusses the question of how the legal framework in the area of culpability determination could be applied to offenses committed with the use of AI. The article presents an analysis of the current state in the sphere of criminal law for both intentional and negligent offenses as well as a comparative analysis of these two forms of culpability.

Part of the work is devoted to culpability in intentional crimes. Results of analysis in the paper demonstrate that the law-enforcer and the legislator should reconsider the approach to determining culpability in the case of the application of artificial intelligence systems for committing intentional crimes. As an artificial intelligence system, in some sense, has its own designed cognition and will, courts could not rely on the traditional concept of culpability in intentional crimes, where the intent is clearly determined in accordance with the actions of the criminal.

Criminal negligence is reviewed in the article from the perspective of a developer’s criminal liability. The developer is considered as a person who may influence on and anticipate harm caused by AI system that he/she created. If product developers are free from any form of criminal liability for harm caused by their products, it would lead to highly negative social consequences. The situation when a person developing AI system has to take into consideration all potential harm caused by the product also has negative social consequences. The authors conclude that the balance between these two extremums should be found. The authors conclude that the current legal framework does not conform to the goal of a culpability determination for the crime where AI is a tool.

Do you know your r2?
Authors: Avdeef Alex
Published: August 2020

The prediction of solubility of drugs usually calls on the use of several open-source/commercially-available computer programs in the various calculation steps. Popular statistics to indicate the strength of the prediction model include the coefficient of determination (r2), Pearson’s linear correlation coefficient (rPearson), and the root-mean-square error (RMSE), among many others. When a program calculates these statistics, slightly different definitions may be used. This commentary briefly reviews the definitions of three types of r2 and RMSE statistics (model validation, bias compensation, and Pearson) and how systematic errors due to shortcomings in solubility prediction models can be differently indicated by the choice of statistical indices. The indices we have employed in recently published papers on the prediction of solubility of druglike molecules were unclear, especially in cases of drugs from ‘beyond the Rule of 5’ chemical space, as simple prediction models showed distinctive ‘bias-tilt’ systematic type scatter.

FRETTING CORROSION EFFECT ON FATIGUE RESISTANCE
OF GAS TURBINE ENGINE PART MATERIAL
Authors: BEZYAZYCHNY Vyacheslav F. , SZCZEREK Marian , TIMOFEEV Mikhail V. , LYUBIMOV Roman V.
Published: September 2020

The paper presents the results of a study on the fretting corrosion effect on strength as per the diagrams of
material fatigue of low-cycle and high-cycle loading. An experimental study of the effect of fretting corrosion
on fatigue of a titanium alloy VT3-1 showed that, when choosing a particular technological method to increase
fatigue resistance of gas turbine engine parts operating under fretting corrosion conditions, it is necessary to
take into account the fact that fretting itself is intensive strengthening and at the same time a softening factor
affecting the surface layers of the material. Technological methods of surface plastic deformation treatment
result in a significant change in the parameters of metal surface layer state, which depends on both the type
and duration of treatment. If the power and time parameters of processing are too high, the surface may be
re-cold worked and the surface layer of the material almost completely exhausts the reserve of plasticity, as
a result dangerous microcracks occur, and the formation of particles of flaking metal emerge. Possible ways
using technological methods have been suggested by the authors to improve fretting strength of part surfaces
operating under fretting corrosion conditions.
SELECTION OF LUBRICANTS FOR REFRIGERATION
COMPRESSORS ON THE BASIS OF VARIOUS TRIBOLOGICAL
TESTS
Authors: GÓRNY Kasper , ZWIERZYCKI Wiesław
Published: September 2020

The article presents a proposal to use a simple and transparent method in aiding the decision making on the
selection of lubricants for refrigeration compressors on the basis of various tribological tests. Tribological
studies included full lubrication and poor lubrication conditions for both the lubricants themselves and the oil/
refrigerant mixtures.
The Bellinger method was chosen as a method to support the selection of lubricants. The decision making
aiding process on the selection of lubricants for various mechanisms of mixing lubricating oil with a refrigerant
was presented. A mixture of polyester oils with the R452A refrigerant was chosen for the mixing mechanism
by simultaneous intermolecular diffusion and natural mass convection. However, for the mixing mechanism
only by intermolecular diffusion, a mixture of mineral oils with the R600a was selected.
Simulations were carried out of several decision-making situations depending on the approach of the decisionmaker,
i.e. economic, qualitative, or sustainable. In each of the options, weightings were subjectively assigned
to individual criteria, trying to reflect the approach of decision-maker.
Comparison of the deleterious effects of yaji and cadmium chloride on testicular physiomorphological and oxidative stress status: The gonadoprotective effects of an omega-3 fatty acid
Authors: Ekhoye Ehitare Ikekhuamen , Olerimi Samson Eshikhokhale , Ehebha Santos Ehizokhale
Published: August 2020

Objective: This study investigated testicular oxidative stress status and physiomorphological function in Wistar rats fed with yaji and cadmium chloride (CdCl2).Methods: Sixty male albino Wistar rats (12 per group) were randomly assigned to five groups: group I (control), group II (300 mg/kg.bw of yaji), group III (500 mg/kg.bw of yaji), group IV (2.5 mg/kg.bw of CdCl2), and group V (2.5 mg/kg.bw of yaji+4 mg/kg.bw omega-3). Each group was evenly subdivided into two subgroups and treatment was administered for 14 days and 42 days, respectively. Semen quality (sperm count, progressive motility, normal morphology, and gonadosomatic index), hormones (testosterone, follicle-stimulating hormone, and luteinizing hormone), testicular oxidative stress markers (superoxide dismutase, catalase, glutathione peroxidase, and malonaldehyde) and testicular histomorphological features were examined.Results: Yaji caused significant (p< 0.05) dose- and duration-dependent reductions in semen quality, the gonadosomatic index, testosterone, follicle-stimulating hormone, and luteinizing hormone. Yaji also caused significant (p< 0.05) dose- and duration-dependent decreases in superoxide dismutase, catalase, and glutathione peroxidase activity, as well as increased testicular malonaldehyde levels. Yaji induced distortions in the testicular histological architecture. CdCl2 damaged testicular function by significantly (p< 0.05) reducing semen quality, reproductive hormone levels, and oxidative stress markers in albino Wistar rats. CdCl2 also altered the histology of the testis.Conclusion: This study shows that yaji sauce has similar anti-fertility effects to those of CdCl2, as it adversely interferes with male reproduction by impairing oxidative stress markers and the function and morphological features of the testis.

Published: September 2020

Eugenia involucrata é uma espécie florestal nativa do Brasil com grande potencial para uso madeireiro, frutícola e medicinal. O presente estudo objetivou avaliar a influência de fitorreguladores e da luminosidade sobre a calogênese em discos foliares de Eugenia involucrata. Foi conduzido um experimento bifatorial (2x5), cujos tratamentos consistiram na combinação da ausência ou presença de luz durante o cultivo e de cinco diferentes empregos de fitorreguladores: ANA, 2,4-D, BAP e as combinações ANA + BAP e 2,4-D + BAP, todos a 5 μM, em meio nutritivo MS. Após 45 dias de cultivo in vitro foi observado que a ausência de luz durante o período de cultivo reduz a oxidação fenólica favorecendo, assim, a calogênese , especialmente na presença de ANA e das combinações ANA + BAP e 2,4-D + BAP. O uso de 2,4-D e de BAP, isoladamente, não é favorável à calogênese em discos foliares de Eugenia involucrata.

The effect of music on the perception of outdoor urban environment
Authors: Franěk Marek , Režný Lukáš , Šefara Denis
Published: September 2020

Music may modify the impression of a visual environment. Most studies have explored the effect of music on the perception of various service settings, but the effect of music on the perception of outdoor environments has not yet been adequately explored. Music may make an environment more pleasant and enhance the relaxation effect of outdoor recreational activities. This study investigated the effect of music on the evaluation of urban built and urban natural environments. The participants (N = 94) were asked to evaluate five environments in terms of spatio-cognitive and emotional dimensions while listening to music. Two types of music were selected: music with a fast tempo and music with a slow tempo. In contrast with a previous study by Yamasaki, Yamada & Laukka (2015), our experiment revealed that there was only a slight and not significant influence of music on the evaluation of the environment. The effect of music was mediated by the liking of music, but only in the dimensions of Pleasant and Mystery. The environmental features of the evaluated locations had a stronger effect than music on the evaluation of the environments. Environments with natural elements were perceived as more pleasant, interesting, coherent, and mysterious than urban built environments regardless of the music. It is suggested that the intensity of music may be an important factor in addition to the research methodology, individual variables, and cultural differences.
Factors Influencing Rehabilitation Motivation of Veterans after a Stroke
Authors: Seo Min-Young , Yang Jinhyang
Published: September 2020

Purpose: Rehabilitation motivation is very important for veterans who have had a stroke because they already have primary disabilities they suffered during their official duties. The purpose of this study was to identify factors associated with the rehabilitation motivation of hospitalized veterans after a stroke.Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 128 veterans hospitalized following a stroke in five veterans’ hospitals in five major cities in South Korea. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with the SPSS 25.0 program.Results: There were statistically significant differences in rehabilitation motivation according to monthly income and time since duagnosis. The rehabilitation motivation of these veterans showed significant positive correlations with self efficacy and social support, and a significant negative correlation with depression. Multiple regression analysis for rehabilitation motivation revealed that the significant predictors were self efficacy, family support, time since diagnosis and monthly income. These factors explained 35.6% of the variance.Conclusion: The results indicate a need to enhance self efficacy and social support to improve the rehabilitation motivation of veterans. The findings also suggest that individual characteristics through time since diagnosis and monthly income should be considered for tailored interventions related to rehabilitation motivation. Furthermore, it is necessary to develop programs enhancing self efficacy and social support to improve the rehabilitation motivation for veterans who have had a stroke.

A Values-Based Analysis of Recovery-Oriented Practice in Mental Health Care and Medical Assistance in Dying
Authors: Macri Rosanna , Wagner Frank , Stuckey Melanie I.
Published: September 2020

The Criminal Code of Canada has been amended to allow medical assistance in dying (MAiD) under prescribed criteria. There has been considerable debate regarding whether people with mental illness as the sole underlying medical condition should be eligible. It is argued that access to MAiD is not compatible with recovery-oriented care. Based on a comprehensive analysis exploring the ethical principles guiding decision making around MAiD, this paper offers a discussion of the compatibility between MAiD and recovery-oriented care and demonstrates significant overlap of these principles. The discussion around MAiD as an option in recovery-oriented care is legitimate and needs to continue.

This study was conducted to explore the effects of ascorbic acid supplementation on serum liver function tests in healthy individuals. A total of 200 subjects were selected randomly. 100 were given ascorbic acid supplementation for 30 days. The other 100 were not given ascorbic acid supplementation, and serum ascorbic acid level and liver function profile was observed before and after intake of ascorbic acid in group A and without intake in group B. The liver function parameters determined were aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), serum total bilirubin, direct bilirubin, indirect bilirubin and serum protein (total protein, albumin and globulin). These parameters along with serum ascorbic acid were measured before and 30 days after vitamin C supplementation. Various parameters of liver function profile were improved swiftly when compared to other group which was not given ascorbic acid supplementation. While comparing the two treatment groups for 30 days, statistically significant improvement was seen in serum ascorbic acid levels (p<0.001) along with improvement in some components of liver function profile such as serum ALT (p<0.01), AST (p<0.01), Total Bilirubin (p<0.01) and Direct bilirubin (p<0.001), Total Proteins (p<0.01) and Albumin (p<0.001) in group A as compared to Group B (without vitamin C supplementation intake). Conclusively, Liver Functions were significantly improved with vitamin C supplementation, giving the supportive evidence of the use of vitamin C as an antioxidant.

Sorghum [Sorghum bicolor (L.)Moench] is widely cultivated but the productivity is very low due to different factors such as Striga hermonthica. Field trails were carried out at Humera location to determine the management of striga to different rates of herbicide application to increase sorghum yield during 2017 cropping season. The trail consisted of eight treatments; 0 (control), 10, 15 and 20gha-1 rates of Chlorsulfron. The herbicide rates were assigned to the main plot while sorghum varieties were assigned to subplots, replicated three times in a split plot design. The data of days to 50%emergence, 50%flowering, plant height at maturity, Panicle length, panicle weight (g), yield per panicle (g), 1000 seed weight (g), grain yield (kg ha-1), above ground dry biomass (kg ha-1) and striga data days to first striga emergence, days to first flowering, number of striga count, branch number per striga plant, striga count per sorghum plant, striga height and biomass (kg/m2 respectively. Partial budget analysis was computed to assess the economic visibility of herbicide application where recorded. Result showed that application of herbicide rates and varieties increased plant height, panicle length, number of heads harvested per plot, panicle weight, yield per panicle, 1000 seed weight and grain yield over the control. Maximum grain yield (3725kg ha-1) was obtained from application of 15 g ha-1 Chlorsulfron with variety Deber. Days to first flowering, striga count per sorghum plant, stand counts of striga at 45DAP, 65 DAP and 85DAP M-2, branch number per plant, plant height and biomass of striga were significantly (P<0.01) affected with the application of herbicide rates and varieties. The partial budget showed that an investing of 1.0 birr on application of herbicide with varieties earn 2.34 birr. Generally, application of Chlorsulfuron75% WDG and use local variety with high yielder could be an advantage to obtain highest yield and profit for the farmers in striga infestation areas.

Identifying the effects of temperature on coronavirus disease (COVID-19) outbreak is essential for modelling studies and guiding intervention strategies all over the world. The aim of the study is to understand the effect of temperature on global epidemic trends, geographic distribution, and transmission patterns of COVID-19. Data on COVID-19 and temperature from 1st February 2020 to 30th April 2020 were included. The epidemic trends we analyzed using both descriptive and inferential statistics; the growth of affected countries was by descriptive analysis; and the global distribution and transmission trend by inferential statistics. Scattered plot diagram matrix was performed for Europe and Africa data. Based on 90 days COVID-19 affected and death data survival analysis was performed for South East Asian region. Lowest three months average temperature was in Europe (41.060F) from February 2020 to April 2020 (34.60F, 41.10F and 47.50F) shows the highest average confirmed case. Highest three months avg. temperature was Africa (74.40F) February 2020 to April 2020 (73.40F, 74.70F and 75.30F) shows the lowest avg. confirmed case and avg. death. In Europe, average temperatures with transmission positively correlated on the other hand in Africa average with transmission were negatively correlated. The results of the study suggested that, temperature had positive or negative effects on the geographical trend of COVID-19 confirmed cases, death cases, recovered case or transmission. It is being suggested that geographical regions with a lower temperature need to adopt the stricter control measures and WHO is a guideline to prevent rapid spread of COVID-19.

Character association studies will help to assess the relationship among the yield and its components for enhancing the usefulness of the selection. In view of this, the present research work was carried out to assess the correlation coefficient and path analysis among twenty five maize genotypes using eleven quantitative parameters. Correlation studies indicated that plant height (cm), ear height (cm), ear length (cm), ear girth (cm), number of kernel rows per ear, number of kernels per row showed significant positive association with grain yield (Kg/ha) as well as among themselves at phenotypic and genotypic level. Hence, selection for any one of these characters would bring in simultaneous improvement of other characters and also finally improvement in grain yield (kg/ha). Path coefficient analysis revealed that the highest positive direct effects on grain yield  was exhibited by days to 75% tasseling, ear length, days to 75% brown husk, ear height and ear girth. Therefore, present investigation could be helpful in a reliable selection of parental lines based on the above given traits as well as for the development of high yielding verities for further breeding programs.

The nutritional composition, mineral content as well as anti-nutritional of Tree spinach (Cnidoscolus aconitifolius) leaves were investigated using standard methods. The results of the investigation showed the presence of moisture to be 5.64±0.30%, ash- 9.27±0.16%, crude protein- 8.43±0.34%, crude lipid- 4.43±0.16%, crude fibre- 16.73±0.20%, carbohydrate- 55.50% and calorific value- 276.04%. The Mineral elements determined were calcium- 1.48±0.12 mg/100 g, phosphorus- 0.18±0.03 mg/100 g. Compounds or substances which acts to reduce nutrients intake, intake digestion, absorption and utilization and may cause adverse effects are referred to as anti-nutrients or anti-nutritional factors. The anti-nutritive content of Cnidoscolus aconitifolius was classified into three categories; fresh leaves, blanched leaves and cooked leaves which decreased significantly. The anti-nutritional content includes; oxalate- which decreased from 62.71±0.21 mg/100 g in fresh leaves, 40.07±0.09 mg/100 g in blanched leaves and 30.04±0.05 mg/100 g in cooked leaves. Phytate- which decreased from 77.17±1.84 mg/100 g in fresh leaves, 62.02±0.16 mg/100 g in blanched leaves and 28.64±0.88 mg/100 g in cooked leaves. Hydrogen cyanide- decreased significantly from 171.22±0.44 mg/100 g in fresh leaves, 113.00±0.08 mg/100 g in blanched leaves and 0.00ab in cooked leaves. Boiling increased the saponin content to 220.30±0.47 mg/100 g in cooked leaves from 218.50±0.50 mg/100 g in fresh leaves and 218.50±0.50 mg/100 g in blanched leaves. Tannins- decreased significantly from 18.30±0.16 mg/100 g in fresh leaves to 11.62±0.15 mg/100 g in blanched leaves to 7.86±0.05 mg/100 g in cooked leaves respectively. A Statistical Package for Social Science (SPSS), version 23 was the statistical tool used for the Analysis of Variance (ANOVA). These results showed that this plant will be a good and rich source of nutrients if it is well processed to reduce its anti-nutritional content.
