Published: June 2021

Background: A new corona virus was subsequently identified and was temporarily named the 2019 new corona virus. On 30th January 2020, the World Health Organization (WHO) announced that the emergence of a replacement corona virus (2019-nCoV) was a public health emergency of international concern. Infectious diseases became one among the main threats to global public health within the twenty first century; such diseases impact both physical health and psychological state. PTSD in youth is common and debilitating. In contrast to adult PTSD, relatively little is understood about the neurobiology of paediatric PTSD. This study is an effort to explore the Assessment of suspected covid 19 children for perceived levels of stress during covid 19 outbreaks.
Methods: The information required for the study was obtained through online means. Consent was obtained orally over phone before proceeding with the study. The questionnaire consisted of demographics variables and the questionnaire was shared online via Whatsapp and/or other means. The questionnaire was given in English.
The Children’s Impact of Event Scale (CRIES 13) was used and the questions were multiple choice question (MCQ) type with 1 best response. In case of the patient not having an appropriate phone they were interviewed over the phone and the collected data was statistically analysed to ascertain any significance and association between each variable.
Results: Out of 54 children, two of them were found to have a score of 30 on CRIES ScaleConclusion: The findings of the study suggest that paediatric PTSD is almost identical to adult PTSD, which has significant p value. It is necessary to recognise the initial psychological impact of the pandemic on children and help them receive immediate attention.

Maquiavelo y el cristianismo como educación política fallida. Un estudio sobre política y religión desde Lluis Duch
Authors: Gutiérrez López Fabian 
Published: June 2021

En el presente texto examino la crítica de Maquiavelo sobre el cristianismo y la educación política que de él emana. Comento pasajes específicos de su obra Discursos sobre la primera década de Tito Libio donde se refiere a la educación política cristiana. Hago esta examinación a la luz de un breve repaso sobre los orígenes del cristianismo, y para ello me baso en diversos pasajes de la Biblia (con especial énfasis en Mateo y Gálatas). Para esta confrontación, retomo la perspectiva de Lluis Duch en su libro Religión y política. Asimismo, como apoyo para mi argumentación, hago intermitentes citas a las obras Política de Aristóteles y el Leviatán de Thomas Hobbes, aunque esto se hará sólo en muy contadas ocasiones.
Barthes: novela y filosofía, en el medio de la vida
Authors: García Soto Luis 
Published: June 2021

En el presente texto, examinamos la elección de Roland Barthes entre la novela y el ensayo como prácticas de la escritura. En 1978, Barthes decidió escribir una novela, motivado por sus posibilidades expresivas. Sin embargo, se percató de que, antes, tenía que responder dos preguntas: qué escribir y cómo escribir. En su opinión, estas dos cuestiones son de naturaleza ética. Tratando de responderlas, Barthes mudó de parecer y, en 1979, escribe un ensayo filosófico. Y fallece en 1980 sin llegar a escribir una novela. En nuestra opinión, si no hubiese muerto en ese momento, Barthes podría haber escrito una novela. Pero, de hecho, la filosofía ofrece (y le ofreció a Barthes) las mismas (o muy semejantes) posibilidades de expresión que la literatura.
Ecos y espejos en la escritura para sanar al otro según Clarice Lispector
Authors: Agraz Rubin Lucía De Lourdes 
Published: June 2021

La obra literaria de Clarice Lispector cobra en estos momentos un halo de misterios desentrañados por la reciente biografía escrita por Benjamin Moser que apuntan a una revisión de su sensibilidad anclada en espiritual judía. En el presente ensayo se hace una análisis filosófico y psicológico del cuento Amor a través de teorías del filósofo judío Buber como eco de la herencia de Clarice y desde la perspectiva lacaniana del torno al reflejo-espejo del yo en el tú como encuentro significativo para el conocimiento de la propia subjetivad. Se traza por lo tanto un esbozo de cómo la literatura deviene un proceso de introspección y de cura.

Developing countries like Nigeria are faced with increased in generation of domestic, industrial and agricultural wastes, with a large percentage moving. This study evaluates the physico-chemical and some heavy metals concentration in three common species of fish from Tungan Kawo reservoir Kontagora, Nigeria; using standard methods between (July 2018 – February 2019); at four different sampling stations of human activities on the water. Five heavy metals were evaluated (Lead, Copper, Manganese, Iron and Chromium) in the fish samples. Phosphate (0.4 – 2.5) mg/L, Nitrate (3.2 – 7.5) mg/L, Temperature (27 – 32.4) 0C, Dissolved Oxygen (2.4 – 5.2 mg/L), Conductivity (81 – 125 µS/cm), Biochemical Oxygen Demand (1.9 – 4.4 mg/L), Alkalinity (mg/L) and Total Dissolved Solids (117 – 198) ppm were within the standard for drinking water and survival of fish. However, the pH (6.3 – 9.8) was above the standard for NIS and WHO drinking water but can support aquatic life. Iron (0.64 ± 0.072 mg/kg) was the most highly concentrated in Synodontis clarias while lead (0.01 ± 0.013 mg/kg) was the lowest in Oreochromis niloticus and Coptidon zillii (formerly Tilapia zillii. This current finding indicates that the water is safe for both aquatic life and domestic purpose but not suitable for direct human consumption without being properly treated. However, there is the need for regular monitoring of the heavy metals load in this water body and the aquatic organisms because of the long term effects

Published: June 2021

Acacia belongs to the family fabaceae among the largest legume genera consisting of eighteen species with the majority of the species distributed in tropical and sub-tropical Africa. Classification of Acacia have remained a daunting task due to it wide spread and also hampered by is large number of species ,prevalence of morphological convergence. Morphological variations in foliar, thorn, inflorescence of some Acacia species found in Zaria for their taxonomic identification at species level were evaluated were Seven species and one variety of Acacia were taxonomically classified using morphological characters. In almost the species leaves were compound bipinnate, alternate and pinnulesare oblong. However the pinnules of A. senegal are obovate. In A. auriculiformis the leaves are simple and sickle-like in shape. Leaves texture ranges from glabrous to pubescent and leaf margin were entire in all the species. The morphological measurement parameters were analyzed using ANOVA cooperation and the results indicate variations among the species. The variations observed in some of the characters could be of taxonomic importance in the identification of the species. Overall ranking indicated that Acacia sieberiana var sieberiana and Acacia sieberiana var villosa were the best with high values of morphological characters of pinna length (3.50±0.11 cm and 3.82±0.16 cm respectively) and number of pinna (18.80±1.32 and 41.70±1.52 respectively). The high values of pinna could be used in solving taxonomic problems associated with Acacia species and in mapping out breeding strategies for the production of cultivars with better foliar yield of Acacia species in Nigeria

Published: June 2021

To explore the relationship between the dry matter contents of potato tubers and metabolic enzymes, an experiment was designed. Ten individual indicators, including metabolic enzymes, could be reduced to 4 comprehensive indicators by using a principal component analysis. Using these 4 components as independent variables (X) and the dry matter content as the dependent variable (Y), the following linear regression equation was obtained: Y = ‒51.802 ‒ 1.022X5 ‒ 0.034X6 + 0.872X9 + 0.286X10 (R2 = 0.889, P = 0.012). In a comparison between the dry matter contents (22.74, 16.58 and 20.72%) calculated according to the equation and the measured value (22.96, 17.09 and 19.75%), the absolute error was < 1% and the estimation accuracy was > 95%. These results indicated that the linear regression equation can be used to predict accurately and quickly the dry matter contents during the tuber enlargement stage.

Published: June 2021

In this study, effects of bloodmeal on onion (Allium cepa L. CV. BARI peaj-1) cultivation to increase yield and related attributes have been tested. The effect of blood meal as fertilizers has been compared with growth hormone treatment and other conventional fertilizer. In the field, the different amount of growth elements treated were at the rate of 2550, 241.90 and 0.17 kg/ha for blood meal, urea and gibberellic acid (GA3), respectively. The yield performance was 172.84, 189.59 and 153.34 MT/ha for GA3, urea and blood meal, respectively. Using GA3 is expensive, and use of urea, a chemical fertilizer, can have adverse effect on soil. Blood meal, a biological ingredient, appears to be a bio-rationale amendment for production and sustained yield of onion. The results will need to ground truth tested in the field.

Published: June 2021

The vanadium(IV) extraction from acidic sulphate medium by Cyanex 301 (bis-(2,4,4-trimethylpentyl) dithiophosphinic acid) dissolved in kerosene is explored from the modelling point of view. The time of equilibration is only 10 min and above pH(eq) = 2, high extraction (>90%) occurs.On keeping organic to aqueous phase ratio of 1, factors affecting the extent of extraction (log D and log CD) are pH(eq), [V(IV)],[SO4 2-], [Cyanex 301]and temperature (T). The high (+) and low (-) levels are considered for the factors. The 25 factorial design is used to find the regression equation for the V(IV) extraction by Cyanex 301. On symbolizing pH(eq), log [V(IV)], , log [SO4 2-], log [Cyanex 301], and 1/T (K-1); where concentration terms are in mol/L, as P , M, S,E, and (1/T), respectively,the regression equation obtained is: log CD = 1.95 - 0.23 M + 1.83 P + 2.07 E + 0.84 S - (888.9/T) - 0.26 PS.The current system shows only the interaction effect among pH(eq) and [SO4 2-]. The equation can well describe the system,and it can be used to optimize factors for satisfactory extraction.

Authors: Naznin Rubait , Nessa Akhtarun , Nazrina Sayeda 
Published: June 2021

Introduction: Cigarette smoking is an intractable public health problem that carries a threat to the health of the entire population. Smoking is a known risk factor for chronic obstructive pulmonary diseases, cardiovascular diseases, certain cancers especially lung cancer.
Objectives:To assess the effect of cigarette smoking on peak expiratory flow rate (PEFR) among cigarette smokers and examine whether PEFR differs between cigarette smokers and non-smokers.
Materials and Methods: This is cross-sectional comparative study was done for one year from July 2014 to June 2015. A total of 150 subjects were recruited from the medicine and allied outpatient departments of Mymensingh Medical College Hospital and Mymensingh locality. They are divided into 50 non-smokers (Group I) and 100 smokers (group II) with a duration of smoking 5-10 years (group IIA) and more than 10 years (Group IIB). PEFR was recorded by using Wright’s mini Peak flow meter. A questionnaire including demographic data was completed in all cases. The data were collected and analyzed using SPSS version 11.5.
Results: Mean PEFR among non-smokers was 449.20±6.83 L/min whereas among smokers of 5-10 years duration(Group IIA) and above 10 years duration (Group IIB), it was 301.20±2.17 L/min and 297.80±2.54 L/min respectively. Mean PEFR values were significantly lower in smokers than non-smokers of both groups.
Conclusion: Cigarette smoking has deleterious effects on lung function causing a significant reduction of PEFR in smokers compared to nonsmokers. Coordinated national strategies for tobacco prevention, cessation, and control are essential for the establishment of a smoke-free environment.
