Authors: Adriano Anaya Lourdes , Quezada ArgÃ¼ello S. Nevy , Rincón Rabanales Manuel , Coronel Niño Rito , Ovando Medina Isidro , Salvador Figueroa Miguel
Published: October 2019

Se estudió el impacto de la actividad humana en el suelo de la Reserva de la Biosfera â€œEl Triunfoâ€, Chiapas. Para ello se determinaron, a lo largo de un año, los valores de 14 parámetros, seis físico-químicos y ocho bioquímicos, en suelos de bosque, cafetal, pastizal y milpa. Los valores de los parámetros en el suelo del bosque fueron diferentes significativamente a los de cafetal, pastizal y milpa. Tomando como base el suelo de bosque se consideró que la actividad humana alteró negativamente la calidad del suelo. Para tener claridad del nivel de impacto se propuso una escala, de 0.0 a 5.0, identificada como Ãndice de Deterioro del Suelo (IDS), y se desarrolló el procedimiento para determinarlo en los suelos con alteración humana. El suelo de milpa tuvo el mayor valor de IDS, ubicándose en el rango de alta degradación. Los suelos de cafetal y de pastizal se ubicaron en el rango de mediana degradación. El procedimiento y escala de IDS se reforzó a través del análisis discriminante.

Authors: Aquino López Verónica Donaji , Aguilar Sánchez Genaro
Published: October 2019

Esta investigación se realizó en el Distrito de Riego (DR) 023-San Juan del Río, Estado de Querétaro. En este Distrito, después de la descentralización del agua en 1992, el cuidado de la infraestructura y del recurso hídrico se convierte en responsabilidad tanto de los productores como del sector gubernamental. Se realizó una revisión conceptual de los términos gobernabilidad y gobernanza, analizando los retos que se han presentado dentro del DR, poniendo énfasis en el manejo del agua dentro del mismo. Además se hizo una comparación entre los objetivos de planes y programas establecidos dentro del municipio para el cuidado del agua y lo encontrado en campo. Para obtener la información y datos necesarios se efectuaron entrevistas estructuradas y semiestructuradas durante el periodo 2014-2016. Para el diagnóstico del manejo del agua se utilizaron datos estadísticos otorgados por el DR-023. Se concluye que la poca participación de los actores dentro del municipio se debe a los siguientes factores: falta de tiempo, prioridad a problemas propios, y falta de estructuras gubernamentales capaces de lograr la participación activa de los productores, por lo que estos factores se han vuelto obstáculos para tener una buena gobernabilidad.
Caracterización y clasificación de los productores del altiplano oeste potosino, México: una propuesta de tipología multidimensional
Authors: Coronado Minjarez M. Alexander , Figueroa Rodríguez Katia Angélica , Figueroa Sandoval Benjamín , García Herrera E. Javier , Ramírez López Artemio
Published: October 2019

El crecimiento poblacional y sus demandas hacen que el sector agropecuario sea cada vez más dinámico y complejo, situación que retoma la importancia de la tipología como un instrumento para el desarrollo de políticas públicas, especialmente para zonas áridas y semiáridas. Los objetivos de este trabajo fueron: (i) crear una tipología multidimensional que integre la caracterización y clasificación de los tipos de agricultura (CTA) con la caracterización y clasificación de los tipos de productores (CTP); e (ii) identificar las dinámicas agropecuarias de la región Altiplano Oeste Potosino utilizando una tipología multidimensional. La investigación tuvo como base 1044 encuestas, los datos fueron analizados utilizando como técnica de agrupación el análisis clúster. Los cultivos de frijol, maíz, chile, cebolla y ganado bovino y ovino son la base del ingreso agropecuario y son las principales cadenas productivas de la región. Se identificaron seis tipos de CTA, todos sistemas mixtos que buscan brindar mayor certidumbre en el ingreso, y cinco tipos de CTP; los menos capitalizados fueron los más representativos de la región (52.9 %). Al combinar CTA con CTP para crear una tipología multidimensional se observó que la principal estrategia de supervivencia se basa en la pluriactividad y el acceso a programas sociales y subsidios, donde las labores no agropecuarias representan más de 50 % del ingreso familiar. Se concluye sobre la necesidad de un cambio de paradigma al considerárseles como â€œempleados ruralesâ€ y no como productores ocampesinos, generando la necesidad de una política rural queconsidere esta realidad.

Authors: Awa Dr. Onyeka
Published: October 2019

The aim of this study is to investigate how the African novelists have domesticated the English language to suit their environments, experience and purpose. Specifically, the literary pieces – The Last of the Strong Ones (Strong Ones), House of Symbols (symbols), Children of the Eagle (Children) and the Trafficked of Akachi Adimora-Ezeigbo were x-rayed. This exploration adopted the Hallidian Systemic Functional Linguistics, which highlights how language is used. The textual method of data analysis, the primary and secondary data collection methods were employed and the results showed that the African literary artists in general and the Igbo Nigerian novelists in particular have taken on a unique style of writing in the African vernacular style. For that reason, the speeches of the characters are laced with dignified local appositives, high profile Igbo songs and tales, studded local proverbs, lexical transfers, ritzy transliterations and so on; and these have given African rhythm to the English language. This notwithstanding, the aura, glamour and credibility of the English language as the medium of communication are retained.

Consciousness Binds Consciousness Releases
Authors: Mukhopadhyay Aju
Published: October 2019

Consciousness is one which pervades the whole existence; from material to vital and mental world and beyond. Not only mind or its awareness, nor matter nor senses alone; every being, everything is replete with consciousness. Consciousness as an element may rise high above that psychological stratum to which we give the name of mentality. There is a superconscient stage as well as subconscient. Endowed with mind man is most miserable as he cannot avoid fear and anxiety but he has no clue to control his miseries. The human being is used to collective consciousness which safely guides animals without a tormenting mind but it pulls man down. Collective thought, collective suggestions are formidable influences which act constantly on individual thought with mixture of obscurities and unconsciousness. One needs to be established on his individuality.
A Comparative Study of French and English Auxiliary Verbs
Authors: Ayodimeji Akintoye, Festu
Published: October 2019

Auxiliary verbs in English and French languages are very germane in constructing sentences in both languages. Therefore, this study examines the way auxiliary verbs are used in English and French Languages; and some features where learners of either language may encounter some difficulties in the course of learning. Our attention is drawn to auxiliary verbs because verb is what that makes any sentence functions the way it is. Verb is one of the most important parts of speech in French grammar and also in English .It is through verb that one knows when an action takes place. When a verb helps another verb to form one of its tenses in a sentence, such verb can be said to be auxiliary. This paper also focuses on auxiliary verbs and how verbs are used in the past and present indications. Auxiliary verbs cannot stand or function alone without relying on the main verb in both English and French languages. Finally, we shall concurrently consider in this paper how semi-auxiliary verbs function as modal auxiliary in French.

Molière’s Tartuffe: A Foucauldian Reading
Authors: Ismailinejad Zahra Sadat
Published: October 2019

The present study discusses Foucault’s concern with the nature of power in human society. As the concept of power is a major challenge in communal societies, he believes that there is no longer a single dominant power. The play portrays this challenge for obtaining power and the resistance it faces that can be best analyzed in a philosophical term. The paper shows how various orders of power are at work in a house which is very similar to a battlefield. As a classical play, one may think that the father is the head of family and has the final say but it is obvious that different members of the family, even their servant resist this kind of power. So, the paper analyses the status of power structure in a classical play.
Stephen Gill Pens Poetry for Personal Therapy
Authors: Rao Dr. Aksa
Published: October 2019

About 300 years before Christ, Aristotle describes catharsis  in his Poetics to show the impact of true tragedy on the audience. In the nineteenth century, Josef Breuer, the companion of Sigmund Freud, was the first to use Aristotelian concept in the realm of psychology. One template of catharsis is the use of a musical instrument for a tired person to feel relaxed. In literature, one example is Oedipus Rex in which Oedipus unknowingly marries his biological mother. Another example is Shakespeare’s Romeo and Juliet. It is often said that reading any work about murder or to see it on the television can be a healing therapy.

Langston Hughes was conceived on February 1, 1902, in Joplin, Missouri. He distributed his first lyric in 1921. He went to Columbia University, yet left following one year to travel. He proceeded to compose incalculable works of verse, writing and plays, and in addition a prominent section for the Chicago Defender. He passed away from this world on May 22, 1967. (Editors, 2014) When you were younger, has anyone treated you good or bad according to your behavior? Or do you remember any incident of your life in which you made a mistake and someone offered you a chance for changing your life? Langston Hughes' short story, “Thank You, Ma'am”, distributed in 1958, catches the two circumstances. Langston Hughes was a vital and productive essayist amid the Harlem Renaissance of the mid twentieth century. He expounded on African-American life and experience. Much thanks to You Ma'am is about what happens when a high school kid and a more seasoned working lady crash on a Harlem road. There are three major topics present in “Thank You, Ma'am”: Forgiveness and Empathy, the Power of Love and Trust, and Christian Charity. At the point when Roger first grabs the handbag of Mrs. Luella Bates Washington Jones, she wrestles him and hauls him to her outfitted room at the back of a house.

Improved method for separation of silver nanoparticles synthesized using the Nyctanthes arbor-tristis shrub
Authors: Gupta Aakash , Koirala Agni Raj , Gupta Bikash , Parajuli Niranjan
Published: October 2019

Plant-mediated synthesis of silver nanoparticles through green chemistry approach has evolved into a new era of research; however, the heterogeneous size and dispersity of silver nanoparticles have limited its applications, such as surface-enhanced Raman scattering, plasmon resonance, and more specifically in the medical field of target drug delivery and therapeutic activity. Here-we investigated the effect of purification and separation modes on the dispersity, size, and morphology of silver nanoparticles, synthesized by plant extract (Nyctanthes arbor-tristis). Transmission electron microscopy revealed silver nanoparticles with an average diameter of 13.0 nm when synthesized through ethanol precipitation, which is advantageously smaller. This result suggests that the silver nanoparticles size can be fine-tuned by changing the separation mode during purification from plant extract. Due to uniformity, our obtained nanoparticles can be expected to show higher catalytic activity towards photochemical reactions, drug delivery and antibacterial activity due to the absence of inactive coating layer (capping agent).
Growth of Potato Shoot Cultures on Media with Antibiotics for Elimination of Bacterial Contamination
Authors: Gubišová Marcela , Gubiš Jozef
Published: October 2019

The aim of our work was to evaluate the effect of selected antibiotics on the growth of potato shoot cultures in the Gene Bank of the Slovak Republic collection and to determine the type and dose that may be used to treat potato cultures endangered by endophytic bacteria. Antibiotics Chloramphenicol at doses 20, 50 and 100 mg/L, Gentamycin and Rifampicin in doses 20, 50, 100, 200 mg/L and the combination of Gentamycin and Rifampicin with 100 mg/L of each were used. Growth parameters – the shoot length and the number of nodal segments per shoot and rooting of ten cultivars of Solanum tuberosum L. of different origin were evaluated. Chloramphenicol already at the lowest dose had the strong inhibitory effect on regeneration, growth, and rooting of shoots. Gentamycin inhibited the growth of shoots gradually with increasing dose of it, rooting of shoots was negatively affected using the dose 50 mg/L or higher. Rifampicin up to 100 mg/L had the minimal effect on the shoots growth, rooting of shoots was not affected, but shoots were characterised by smaller or stunted leaves. Although the growth of shoots was affected, all ten genotypes used in the experiments were able to regenerate and grow at the highest dose of Rifampicin and Gentamycin. According to the results, it is highly probable that these antibiotics up to 100 mg/L or their combination would be suitable for culture preservation of the most genotypes in the gene-bank collection. On the other hand, Chloramphenicol cannot be recommended due to its strong detrimental effect on potato shoot cultures.

This paper studies the effects and the changes occur in different rice varieties due to different methods on grain quality and amino acids of rice. Three Egyptian rice cultivars belonging to japonica, japonica/indica and indica subspecies were investigated for grain quality, protein and amino acid composition under three planting methods, i.e., broadcasting, seedling transplanting and dibbling. A strip plot design with three replications was used; the investigated three rice cultivars occupied the horizontal main plot, while three planting methods were devoted to the vertical main plot. The method of planting did not affect significantly the grain dimension, but it affected significantly the milling characters and the 1,000-grain weight. The highest milling characters and 1,000-grain weight came from transplanting, while the lowest one from the dibbling method. There was no significant difference between transplanting and broadcasting in milling characters and 1,000-grain weight. The chemical and cooking characters of grains showed no significant differences in moisture content and gelatinization temperature characters, while the differences in protein content and elongation were significant among the varieties and planting methods. The interaction between the planting method and rice had significant effect on the protein content. The most important essential amino acids according to the FAO/WHO pattern were not affected significantly by the different methods of planting. This means that the biological value of rice grains is not affected by different methods of planting.

Prolonged systematic application of mineral fertilisers contributes to increasing the yielding capacity of agricultural crops. However, it can lead to significant changes in the composition, properties and formation of agricultural soil regimes. The findings of the research have shown that the application of mineral fertilisers leads to the change of radioactive nuclides content in the soil. The research was conducted under conditions of a long-term stationary field experiment (Uman, Ukraine), using different rates of mineral fertilisers N45P45K45, N90P90K90 and N135P135K135. Soil samples (podzolized chernozem) were selected from the depths of 0 – 20, 20 – 40 and 40 – 60 cm. Specific activity of radionuclides was determined by the spectrometric analysis. Using experimental results we have demonstrated that under a long-term application (50 years) different rates of mineral fertilisers effect the specific activity of radioactive isotopes in the soil (226Ra, 232Th, 40K, 137Cs, 90Sr). The specific activity of radionuclides in a podzolized chernozem and in winter wheat grain was established. Winter wheat plants accumulated 232Th at the highest levels, but the use of fertilisers reduced it in a larger mass of the crop. The absorption of radioactive nuclides by winter wheat grain grown after peas and silage corn depending on fertilisation changed similar to growing it after clover as a previous crop. According to the data of specific activity of radioactive nuclides in the soil and winter wheat grain, the coefficient of their biological absorption was calculated.

Fabric-to-fabric friction is involved in the action mechanism of medical compression devices such as compression bandages or lumbar belts. To better understand the action of such devices, it is essential to characterize, in their use conditions (mainly pressure and stretch), the frictional properties of the fabrics they are composed of. A characterization method of fabric-to-fabric friction was developed. This method was based on the customization of the fourth instrument of the Kawabata Evaluation System, initially designed for fabric roughness and friction characterization. A friction contactor was developed so that the stretch of the fabric and the applied load can vary to replicate the use conditions. This methodology was implemented to measure the friction coefficient of several medical compression bandages. In the ranges of pressure and bandage stretch investigated in the study, bandage-to-bandage friction coefficient showed very little variation. This simple and reliable method, which was tested for commercially available medical compression bandages, could be used for other medical compression fabrics.

In the present study we investigated the in vitro hepatotoxicity of a set of rhodamine-labelled 3-hydroxy-4-pyridinones (3,4-HPO) that had previously demonstrated significant inhibitory effect in the intramacrophagic growth of Mycobacterium avium. Our aim was to establish a correspondence between the molecular structure and the in vitro toxicological activity of these compounds.

The impact of a set of bidentate (MRB2, MRB7, MRB8, and MRB9) and hexadentate (MRH7, MRH8, and MRH10) chelators on cellular metabolic competence and membrane integrity was investigated in HepG2 cells.

Our findings indicate that: a) hexadentate chelators are more cytotoxic than parent bidentate ligands; b) disruption of cell membrane and metabolic competence only occurred after 5 days, at the highest concentrations tested; c) strict correlation between bacteriostatic activity and in vitro toxicity was observed, which seems to be directly dependent on the size of the molecule and on the hydrophilic/lipophilic balance; d) among the set of bidentate ligands, carboxyrhodamine derivatives (amide linker) presented lower detrimental effects, when compared with rhodamine B isothiocyanate chelators (thiourea linker); e) contrarily, for the hexadentate series, rhodamine B isothiocyanate derivatives are less cytotoxic to HepG2 cells than carboxyrhodamine molecules; and f) for all compounds tested, when the substituents of the nitrogen atom were switched from ethyl to methyl, an increment of toxicity was observed.

Overall, all chelators seem to display suitable in vitro toxicological potential to combat fast grow bacteria. According to their in vitro pharmacological: toxicological potential ratio, MRH7 and MRH8 may be considered as the most suitable compounds to undergo further pre-clinical development studies.

The aim of the research was to determine some basic biological activities of less biomedically studied but commonly known two fungi from the Boletaceae family Suillellus rubrosanguineus and Tylopilus felleus, which grow in the forests of Middle Europe. The cytotoxicity tests of the ethanol and chloroform extracts were carried out using NIH-3T3 and MCF-7 cell lines. The presence of alkaloids in the extracts was assessed by the reaction with Dragendorff reagent. In all of the extracts the positive reaction with the reagent was observed. In general, the extracts from Suillellus rubrosanguineus were more cytotoxic than the extracts from Tylopilus felleus and exhibited no selectivity of activities on healthy and cancer cell lines. However, the extracts from Tylopilus felleus proved to be selectively cytotoxic for cancer cell line. Tylopilus extracts or their isolated bioactive compounds could be considered for further study in pre-clinical experiments.

Bisphenol A is widely used as a material for the production of epoxy resins and polycarbonate plastics. It contaminates various food stuffs by getting leached out from their container lining. Limited information is available on its effects on the male reproductive system. The aim of the present study was to evaluate the extent to which bisphenol A can affect the reproductive system by measuring biochemical and histological changes in the epididymis. Inbred Swiss strain male albino mice were orally administered 80, 120 and 240 mg/kg body weight/day of BPA for 45 days. After completion of treatment, the animals were sacrificed; cauda epididymis was isolated, weighed, used for biochemical and histopathological studies. The results revealed that BPA administered for 45 days caused significant (p<0.05) and dose-dependent reduction in epididymis weight. There was significant (p<0.05) increase in lipid peroxidation and the acid phosphatase activity. Dose dependent reduction in protein, sialic acid contents, as well as the activity of enzymatic antioxidants and mitochondrial enzymes was recorded compared to vehicle treated group. The effect was dose-dependent. Histopathological alteration was observed. This study concludes that BPA causes toxicity in epididymis of mice by generating free radicals, which may be a possible reason for reduction in sperm parameters.

Handling is a form of experience which can result in physiological changes depending on the period of postnatal age when performed. There is a lot of evidence about the positive effect of neonatal handling, but a lack dealing with handling of adult rats. Behavioral changes and memory deficits are present in dementia-like disorders. In the present work, we tested whether 6 weeks lasting handling of young adult rats could revert memory impairment induced by trimethyltin (TMT) (7.5 mg/kg, intraperitoneally). Testing rats in Morris water maze revealed significant effect of TMT as well significant effect of handling. We observed improvement of spatial memory also between healthy, non-degenerated rats as well as degenerated rats, represented by shorter latency onto the platform. In our paper, we report beneficial effect of handling on spatial memory that is in compliance with published works about beneficial effect of cognitive therapy and training in patients with early stage of Alzheimer's disease and dementia.
