CECÍLIA MEIRELES: O LIVRO E A PALAVRA INVÍSIVEL
Authors: Vieira de Oliveira Ilca 
Published: February 2020

Este texto tem como objetivo trazer à luz uma abordagem crítica sobre o processo de criação artística e a relação que o artista estabelece com a sua própria obra. Ou seja, pretende verificar como determinado livro é deixado à margem pelo escritor ao longo de reedições e publicações de sua produção poética. Destaca-se, aqui, a obra Espectros, primeiro livro de poemas de Cecília Meireles, publicado em 1919. Esses poemas jamais foram reeditados durante a vida da autora e, depois de sua morte, somente em edição de 2001, momento em que se comemorou o centenário de nascimento da poeta. Há exatamente 100 anos, a escritora estreou na literatura com essa coletânea de sonetos, os quais foram suprimidos da edição de sua Obra poética, de 1958, por ela própria. Considerando esse ano como centenário de estreia da autora no mundo das letras, a nossa reflexão irá discutir o processo criativo do poeta, o papel do crítico e o do leitor com base da edição da Obra poética, de 1958.

“BIZARRIA DE ENGENHO”: SILVA ALVARENGA E O POEMA HERÓI-CÔMICO NA DOUTRINA DE FRANCISCO JOSÉ FREIRE
Authors: Melo Samuel Carlos , Vieira Tiago de Jesus 
Published: February 2020

Este artigo tem como objetivo efetuar análise de “Discurso sobre o poema herói-cômico”, texto que antecede O Desertor (1774), poema herói-cômico de Silva Alvarenga. Nesse texto, o poeta luso-brasileiro tenta justificar a opção pelo gênero herói-cômico diante da rejeição dos críticos. São escassos os estudos históricos e críticos de fôlego sobre a obra e, dentre os que tratam diretamente do poema, com algumas exceções, têm-se leituras ainda insuficientes e uma recepção desinteressada, fato que contrasta com a fortuna de Glaura (1801). Sendo assim, faz-se necessário tentar compreender a produção poética de Silva Alvarenga diante das convenções poéticas e retóricas que orientaram as letras no século XVIII. O principal referencial em língua portuguesa desse período é Arte Poética (1748/49), de Francisco José Freire. Pretende-se estabelecer um cotejo entre os pressupostos sobre a natureza do poema herói-cômico expostos por Alvarenga e os preceitos da doutrina poética de Freire, a fim de contribuir para a ampliação dos estudos sobre O Desertor. Para isso, além dos textos já mencionados de Freire e Alvarenga, este artigo se apoiará nas leituras de Aristóteles (1984), Candido (1975) e Genette (1971), e Ivan Teixeira (1999).

Published: February 2020

La utilización de materiales tradicionales como elementos de mampostería en construcciones convencionales constituye una de las mayores causas de muerte durante eventos telúricos debido a su efecto de volcamiento. En Ecuador persiste la utilización de estos materiales a pesar de estar localizado en una zona de alto riesgo sísmico, y en un territorio privilegiado en recursos naturales que no son explotados adecuadamente. La presente investigación tiene por finalidad caracterizar físico-mecánicamente prototipos de biotableros estructurales compuestos tipo sándwich como alternativa de pared portante en construcciones no-convencionales que fomenten el desarrollo sustentable de biomateriales de la zona. 46 muestras extraídas de dos prototipos se ensayaron de acuerdo a la normativa vigente ASTM bajo los modos mecánicos de compresión, flexión, tracción y corte con sus respectivas densidades y contenidos de humedad. Los resultados experimentales fueron validados mediante 40 análisis de elementos finitos procesados en el software LS-Dyna, que a su vez permitieron establecer una proyección de sus capacidades estructurales bajo diferentes condiciones de carga. Los resultados obtenidos reflejan biotableros con una excelente flexibilidad y resistencia mecánica que a su vez se traduce en un alto comportamiento dúctil; lo que permitirá disminuir efectos adversos durante eventos sísmicos de alta magnitud y duración.
Fuzzy Expert System Generalised Model for Medical Applications
Authors: Masivi Osée Muhindo 
Published: February 2020

Abstract
Over the past two decades an exponential growth of medical fuzzy expert systems has been observed. These systems address specific forms of medical and health problems resulting in differentiated models which are application dependent and may lack adaptability. This research proposes a generalized model encompassing major features in specialized existing fuzzy systems. Generalization modelling by design in which the major components of differentiated the system were identified and used as the components of the general model. The prototype shows that the proposed model allows medical experts to define fuzzy variables (rules base) for any medical application and users to enter symptoms (facts base) and ask their medical conditions from the designed generalised core inference engine. Further research may include adding more composition conditions, more combining techniques and more tests in several environments in order to check its precision, sensitivity and specificity.
Minimal Total Weighted Tardiness in Tight-Tardy Single Machine Preemptive Idling-Free Scheduling
Authors: Romanuke Vadim 
Published: February 2020

Abstract
Two possibilities of obtaining the minimal total weighted tardiness in tight-tardy single machine preemptive idling-free scheduling are studied. The Boolean linear programming model, which allows obtaining the exactly minimal tardiness, becomes too time-consuming as either the number of jobs or numbers of job parts increase. Therefore, a heuristic based on remaining available and processing periods is used instead. The heuristic schedules 2 jobs always with the minimal tardiness. In scheduling 3 to 7 jobs, the risk of missing the minimal tardiness is just 1.5 % to 3.2 %. It is expected that scheduling 12 and more jobs has at the most the same risk or even lower. In scheduling 10 jobs without a timeout, the heuristic is almost 1 million times faster than the exact model. The exact model is still applicable for scheduling 3 to 5 jobs, where the averaged computation time varies from 0.1 s to 1.02 s. However, the maximal computation time for 6 jobs is close to 1 minute. Further increment of jobs may delay obtaining the minimal tardiness at least for a few minutes, but 7 jobs still can be scheduled at worst for 7 minutes. When scheduling 8 jobs and more, the exact model should be substituted with the heuristic.
Change of Mechanical Properties of Zinc Coatings After Heat Treatment

Published: February 2020

Abstract
Hot-dip galvanized coatings represent a protection based on passivation of the single zinc layer. It is one of the most commonly used surface treatments of steel. However, pure zinc forms merely an insignificant upper layer. Coating crosscut is formed by intermetallic phases that can cause decrease in the level of anticorrosion protection. This results from an iron diffusion from the base material. Goal of this paper is to analyse the changes in the mechanical properties of these phases in relation to zinc coating heat treatment. For the experiment, annealing temperatures of 200 °C and 300 °C were used, and the staying time was set at 1, 3 and 5 hours. Furthermore, samples without any heat treatment were subjected to comparison as well. Moreover, following tests were conducted: bending test in compliance with the ČSN EN ISO 1519 standard, and tearing test (in accordance with the ČSN EN ISO 4624 standard). On the basis of performed tests, the changes in mechanical properties of the zinc coating after heat treatment could be analysed.

Abstract
Mediterranean semi-arid region is sensitive to physical, chemical and biological soil disturbances related to intensive tillage. Presented field experiment was conducted at Razan district, Hamedan, located in central west zone, Iran during the 2017–2018 growing season. It dealt with the effects of different tillage methods and treatments on growth, yield and yield contributing characters of spring Kabuli chickpea (Cicer arietinum L.) under irrigated condition. Effects of two tillage methods – inversion tillage (mouldboard ploughing – T1) and non-inversion tillage (chisel ploughing – T2) – in combination with five different fertilization treatments (C: complete fertilizer; 20FYM: 20 Mg·ha−1 farmyard manure; 40FYM: 40 Mg·ha−1 farmyard manure; NPK: nitrogen, phosphorus, and potassium at 2-1-1 ratio; 0: no fertilizer for the control purposes) were studied. The experiment was carried out in split block design with three replications. Results showed that application of 40FYM under T1 condition significantly decreased the number of days to seedling emergence. The highest number of days to flowering was recorded for plants cultivated with inorganic fertilization and reduced tillage. Application of large amounts of FYM significantly increased the ground cover and canopy width for both tillage methods. The highest number of secondary branches was recorded for combination 40FYM – T1, which was followed by C – T2. The pod number per plant was considerably sensitive to different combination of treatments and the best results were recorded for combinations 40FYM – T2; 20FYM – T2; and 40FYM – T1. A similar trend was also recorded for the total dry matter. The heaviest seeds were observed in cases with the application of high levels of FYM. The highest seed yield was observed for plants cultivated using 40FYM – T2. Furthermore, the highest harvest index was recorded for 40FYM – T2, and C – T2. The results indicate that non-inversion tillage together with high-level FYM application can significantly affect the yield levels.
Factors Affecting the Adoption of Agricultural Automation Using Davis’s Acceptance Model (Case Study: Ardabil)

Published: February 2020

Abstract
Taking into account that traditional agricultural methods reduce the farm performance and make agriculture economically ineffective, development of intelligent machinery is essential for improving the quality of crops and agricultural activities. The most important issue in development of agricultural technologies lies in users’ willingness to adopt it. Therefore, the purpose of this study is to investigate the key factors of Davis’s model in automation acceptance in agriculture. Presented paper describes an applied research with a survey approach through a questionnaire. Questionnaire data were collected from 378 people and respondents include university students, farmers and experts in a randomized sampling from the Ministry of Agriculture. Firstly, the questionnaire data were described in a form of statistical numerical characteristics. Secondly, in order to verify the data normality, the Kolmogorov-Smirnov test was calculated in SPSS and the relationship between the variables was investigated in the conceptual model. Subsequently, hypotheses were tested via appropriate statistical models using LISREL and SPSS software. The results showed that for all hypotheses, the T-test exceeds 1.96 and the significance level is less than 0.05. In such a manner, all hypotheses were confirmed at 95% level, and the path coefficients in the hypotheses H1, H2 and H6 were negative – indicating the negative effect of the independent variable on the dependent variable in the hypothesis. In the other hypotheses, these were positive – indicating the positive effect of the independent variable on dependent variable. By means of modelling, it was found that there was an inverse relationship between social and individual factors with perceived usefulness, as well as an inverse relationship between social factors with perceived ease-of-use, while there was a positive and significant relationship between other factors. According to a set of fitting indices, the research conceptual model was appropriate and Cronbach’s coefficients for each factor were greater than 0.7, suggesting that the questionnaire was valid. On the basis of findings, the better a person understands the usefulness of automation, the more likely this person is to adopt it. Since the risk and issues related to it play an important role in farmers’ decision making, it is recommended that future studies address the issue of risk in adopting precision farming technology.

Published: February 2020

Abstract

Ammi visnaga (Av) is a source of khellin where a tea made from the fruit of this plant was used as herbal medicine for kidney stones in Egypt. In the present research, the acute and subacute toxicity studies with oral intake of 150, 300 and 600 mg/kg of Av seed ethanolic extract in rats were done. In acute toxicity test, 4 groups of rats (n = 6/group: 3 males and 3 females) were chosen and the first control group received tap water, while the other three groups received Av seed ethanolic extract dissolved in tap water at doses of 150, 300, and 600 mg/kg, and general behavior, adverse effects, and mortality were recorded for up to 14 days. In subacute toxicity study, 72 rats (36 males and 36 females) were divided into 4 major groups; group I received tap water (control group), while animals in groups II, III, and IV (test groups) received oral intake of Av seed ethanolic extract dissolved in tap water at doses of 150, 300 and 600 mg/kg bwt, respectively. Each of this major group was subdivided consequently into 3 subgroups (n = 6/group: 3 males and 3 females) where brain tissue, blood sample, body and organs weights were recorded at the beginning and then after two and four weeks of the experiment for the determination of hematological, biochemical and histopathological changes in tissues (liver, kidney, brain, spleen, heart, testis and ovary). With regard to acute toxicity, Av seed ethanolic extract did not induce any toxic effects or death or any organ toxicity. In subacute toxicity study; oral intake with Av seed ethanolic extract did not reveal any change in body and organs weights, hematological parameters, serum glucose and cholesterol, brain neurotransmitters, liver and kidney functions, male and female hormones. In conclusion, Av seed ethanolic extract is nontoxic to liver, kidney, brain, spleen, heart, testis and ovary.

Abstract
The present study was designed to investigate the chemoprotective effect of green tea extract (GTE), rosmarinic acid (RA) and rosemary extract (RE) against diethylnitrosamine (DEN) initiated and ferric nitrilotriacetate (Fe-NTA) promoted nephrotoxicity in rats. Forty male rats were categorized into five: Group I included healthy rats, group II received DEN+Fe-NTA, group III received 200 mg/kg b.wt. of RE+DEN+Fe-NTA, group IV received 1 g/kg b.wt. of GTE+DEN+Fe-NTA and group V received 50 mg/kg b.wt. of RA+DEN+Fe-NTA. RE, GTE, RA were given orally for 14 days before single intraperitoneal administration of DEN (160 mg/kg) till the end of the experiment. Eighteen days after DEN, a single intraperitoneal dose of Fe-NTA (5 mg Fe/kg) was administrated to rats to promote nephrotoxicity. The biochemical parameters were analyzed in serum at time intervals while the malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) were assessed in both serum and renal tissues. Kidney from each group was histopathologically examined at time intervals. The administration of Fe-NTA after DEN dose to albino rats resulted in acute nephrotoxicity which was characterized by a highly significant elevation of serum urea, creatinine, uric acid (p=0.000), serum and renal MDA and TNF-α (p=0.000) with vacuolation of epithelial lining renal tubules. The administration of RE, GTE and RA prior to DEN+Fe-NTA treatment significantly ameliorated the observed increased levels of the above mentioned parameters. GTE, RA & RE exerted a protective effect against renal toxicity with GTE showing a more pronounced effect on renal function parameters while RA showed the best antioxidant impact.
Plasma paraoxonase1 activity in rats treated with monocrotophos: a study of the effect of duration of exposure

Abstract
We have earlier demonstrated the potential of monocrotophos (MCP), a highly toxic organophosphorus insecticide (OPI), to elicit insulin resistance in rats after chronic exposure. Given the understanding of role of paraoxonase1 (PON1) in OPI toxicity and diabetes pathology, this study was envisaged to understand the effect of duration of exposure to MCP on plasma PON1 activity in rats. Rats were administered MCP per os at 1/20 and 1/10th LD50 as daily doses for 180 days. Interim blood samples were collected at 15, 30, 45, 90 and 180 d for analysis of plasma parameters. Exposure to MCP for 45 resulted in persistent trend of hyperinsulinemia, while significant increase in fasting glucose levels was observed after 180 days. MCP caused suppression of plasma cholinesterase activity though the study period, albeit extent of inhibition was more severe during the early phase of the study. Exposure to MCP for 180 d resulted in hypertriglyceridemia and marginal decrease in HDL-C levels. MCP failed to modulate PON1 activity in plasma during the early phase of the study (up to 45 d). However, prolonged exposure resulted in significant increase in the plasma PON1 activity. This suggests that manifestation of insulin resistance in rats subjected to chronic exposure to MCP is associated with increase in PON1 activity. Our work provides rationale for studying whether the increase in PON1 activity observed in the present study serves to counter the deleterious effect of long term exposure to organophosphorus insecticides on metabolic homeostasis.

Abstract
Effective urban transportation no doubt serves as engine room and catalyst for driving national economic development. Significantly, the purpose of urban transport is to provide both passenger and freight mobility over specific parts of urban areas including cities, and its efficiency is characterized upon transporting effectively and achieving economies of scale. Hence, this study examined intra-city mobility and characterization in Lagos, Nigeria. The data was sourced from both primary and secondary sources. Primary data detailed the use of two sets of questionnaires administered to commuters and motorists. 182 copies of questionnaire were randomly administered to commuters, while 60 units of the questionnaire were purposively and conveniently administered to motorists. Descriptive and inferential techniques were used for data analysis. Major findings revealed obvious variations in socio-economic parameters of intra-city trip makers and factors influencing trip making. It was observed that journey to work, school, shopping cum business constituted the major trips characterizing in Lagos. Findings also revealed that high patronage priority was given to most used and preferred means due to vehicle travel speed, trip purpose, and availability than safety and comfortability of modal choice. Regression analysis result revealed that commuters’ modal choice and patronage is statistically influenced by operational attributes of mode (e.g. transit time, delay duration, safety, vehicle condition and transit fare etc.) at Sig. p=0.000 and F14
165 15.667 which is greater than table value at 5% significant level. The study recommended among others the formulation and implementation of effective policy for urban transport activities; standardization of service operations and expansion of infrastructural facilities including the last-mile in the city.
