Published: July 2019

The use of vermi-wash as organic source and potassium nutrients were investigated under this study. A field experiment was carried out during two successive summer seasons of 2017 and 2018 under open field conditions in Dokki experimental location, Agricultural Research Center, Giza Governorate, Egypt. The study aimed to evaluate the effect of applying different potassium rates 140, 280 and 420 kg K2O per hectare combined with spray vermi-wash for two, four, six times as well as spray water (control) on vegetative growth, yield of potato (Solanum tuberosum ‘Spunta’). The applications of potassium rates and vermi-wash sprays affected significantly the potato vegetative growth, total and marketable tuber yield as well as nutrient contents (N, P and K %) of potato leaves. Increasing potassium rate from 140 to 280 kg K2O per hectare enhanced total yield. Increasing potassium application to 420 kg K2O per hectare led to decrease the vegetative growth and productivity compared to 280 kg K2O per hectare. Regarding the vermi-wash spray applications, data revealed that two times spray of vermi-wash enhanced vegetative growth and productivity, while increasing spraying of vermi-wash to more than two times led to decrease of potato vegetative growth and productivity.

Published: July 2019

Regarding the significance of environmental issues, the use of herbal compounds is proposed as an alternative method for methyl bromide and phosphine. In this research, the insecticide effect of MeOH extract of Pistacia khinjuk leaves on Tribolium confusum (Jacquelin du Val, 1863) and Oryzaephilus surinamensis (Linnaeus, 1758) was studied. The chemical compounds of the extract were also identified by the GC-Mass device. The contact toxicity test was performed on 1 to 7-day-old insects. LC50 values of 9.32 and 5.47 mg ml–1 were calculated for T. confusum and O. surinamensis, respectively. More than 39 compounds were identified in MeOH extract of P. khinjuk, with 5-ethoxy-4-phenyl-2-isopropylphenol (29.02 %), phenyl ethyl alcohol (10.78 %), benzyl alcohol (7.8 %) and 1, 2-benzenediol (6.67 %) as main compounds. In addition, there were the known insecticide compounds such as spathulenol (2.07 %), myrcene (2.03 %), ρ-cymene (1.67 %), apiol (1.61 %), borneol (0.79 %), and pulegone (0.44 %) in the plant extract that confirmed the potential of the P. khinjuk extract in controlling stored-product insects.

The present study was carried out to analyze bioactive compounds and their their antifeedant activityity in the cashew nut (Anacardiaceae) shell extract against Bemisia tabaci. Hexane was used as solvent in the extraction. The result showed that shell extract of total phenolics, flavonoids and tannins were 63.11 mg gallic acid equivalents g-1; 1.79 mg quercetin equivalents g-1; and 16.04 mg gallic acid equivalents g-1, respectively. Gas chromatography mass spectrometry (GC-MS) analyses showed that anacardic acid has the highest concentration (76.93 %) in the extract. The viscous extract of cashew nut at concentration of 0.75 % was able to inhibit the landing and provided an active role as anti-oviposition on B. tabaci. There were significantly fewer landings than after use of insecticide with imidacloprid active compound at concentration of 0.50 %, after 72 h of application. Mortalities of B. tabaci caused by extracts with concentration of 1.50 % and 3.00 % were not significantly different after 24 and 48 h of application. At concentration of 3.00 % there was no phytotoxic effect. The highest mortality of B. tabaci was obtained at concentration of 6.00 %. However, concentration of 6 % of extract caused phytotoxic symptoms on soybean leaves.
“Episodio en la huerta...", de Agustín Yáñez. Jugar al milano, citar al toro.
Authors: Blancas Noé Blancas 
Published: July 2019

En el relato de Agustín Yáñez “Episodio en la huerta...”, Jacinto, tras mes y medio de convalecencia, observa a sus vecinitos jugando a la ronda “El Milano”, y recuerda que sus primos jugaban esa misma ronda. Sobre todo, rememora las alucinaciones que la fiebre le ha producido. En éstas, se sobreponen ciertas imágenes de la ronda –el toro, el milano, la rosa, el clavel– y otras de la película La alondra y el milano. A través de estas asociaciones, el niño intenta develar el sentido erótico del juego. De tal manera, la ronda no se incorpora a su discurso para constituirse en canto o en juego, que es para lo que se citan las rondas; los fragmentos que de ella se repiten constituyen más bien imágenes o símbolos que se vuelven un instrumento para cobrar conciencia de su deseo y, al mismo tiempo, de la infancia perdida.
Siguiendo la teoría narratológica y las investigaciones de Graciela Reyes sobre el fenómeno de la citación, en este trabajo sostengo la tesis de que no el juego, en el plano actancial, sino la citación de ciertas palabras o frases, en el plano discursivo, le permiten al niño encontrar el sentido de sus alucinaciones y, finalmente, acceder a la revelación del misterio, el despertar de la pulsión sexual.
Los trabajos (críticos) de Persiles y Segismunda (1617)
Authors: Berdeja Acevedo Juan 
Published: July 2019

Este artículo se ocupa de la fusión entre las dominantes narrativa y crítica en Los trabajos de Persiles y Segismunda. Con base en el análisis de determinados pasajes en que tiene lugar una crítica intradiegética sobre las historias —también éstas son intradiegéticas— contadas por uno de los protagonistas (Persiles/Periandro), se busca demostrar que Miguel de Cervantes Saavedra reflexionó sobre su quehacer como escritor de ficción y que particularmente en esta obra pueden hallarse rigurosas ideas sobre lo que hoy llamamos ‘recepción’, ‘proceso de lectura’, ‘crítica’.
Así, si el Quijote es la obra en que se representa al lector obsesivo y los efectos de la ficción, en este trabajo se propone que el Persiles es entonces la obra en que se retrata al receptor obsesivo, el que toma distancia con respecto al relato y es, sobre todo, un crítico muy semejante al filólogo.

Published: July 2019

El espacio se declaró Área Natural Protegida (ANP) desde 1996 y en el año 2000, se determinó su recategorización como Parque Nacional Arrecifes de Cozumel (PNAC). Desde su creación ya existían servicios turísticos en su área de influencia, mismos que se han incrementado con el paso de los años. La metodología consistió en la revisión de literatura vinculada con el tema, realización de cinco talleres con permisionarios y cooperativistas, 12 entrevistas a informantes clave, cuatro recorridos en la zona de estudio y área de influencia para levantamiento de datos georreferenciados y llenado de fichas de observación. El objetivo fue revelar la organización territorial y el aprovechamiento turístico en el PNAC, entre los resultados se encontró una fuerte intensidad de las actividades turístico recreativas en las zonas arrecifales del PNAC, se destacan las fortalezas, oportunidades, debilidades y amenazas en el PNAC y como propuesta de organización del territorio, el establecimiento de unidades funcionales y nodos para el mejor aprovechamiento de los recursos en el ANP, se enfatiza una incompatibilidad entre la zonificación del programa de manejo vigente, con la concentración de las actividades turístico-recreativas que se practican en el área.
Reconversión de cultivos como resultado de la presencia de huanglongbing en Colima, México
Authors: Granados-Ramírez Guadalupe Rebeca , Hernández-Hernández Raciel 
Published: July 2019

El estado de Colima se le conoce como el principal productor de limón. En 2010 se detectó la presencia del Huanglonbing (HLB), enfermedad de los brotes amarillos en esta región, misma que ha ocasionado pérdidas progresivas. Hasta el momento no se conoce cura y la baja rentabilidad de la producción provoca que el agricultor decida retirar la plantación. Así, la reconversión productiva, implica modificar el patrón de producción, mediante el establecimiento de cultivos alternativos con mayor viabilidad agronómica, social y rentabilidad económica. El objetivo de este trabajo fue cuantificar los cambios en los cultivos, además de valorar el potencial de las nuevas plantaciones. Para monitorear, identificar y cuantificar los cambios; se recurrió al análisis de imágenes de satélite, formación y análisis de bases de datos agrícolas, entrevistas y mediciones en campo. Entre otros se comprobó un progresivo aumento en el reemplazo de cultivos, se han sustituido alrededor de 5 000 ha de cítricos, lo que ha significado una reducción de 84,721 ton en el volumen de producción del limón mexicano y una pérdida de 302,636,729 de pesos aproximadamente. La superficie de cultivos emergentes como papaya y piña va en aumento y han representado mayores ingresos económicos para los productores.
Red de estructuración territorial histórica. El caso de la ruta de la Cíbola, en la época colonial
Authors: Gómez-Molina Pedro , Urquijo-Torres Pedro S. , Bocco-Verdinelli Gerardo 
Published: July 2019

La llamada Ruta de Cíbola es el resultado de una serie de expediciones emprendidas desde el siglo XVI – aprovechando antiguos caminos y senderos prehispánicos–, que permitió la incursión y expansión colonial hacia el septentrión noroccidental novohispano. La ruta fue estudiada, entre otros, por Carl O. Sauer, dándola a conocer a nivel internacional. Nuestro propósito en esta ocasión es analizar cartográficamente este camino, así como las implicaciones territoriales que de él derivaron. Analizamos los cambios geográficos que se suscitaron con el avance fronterizo colonial. Es de resaltar que este camino de profundo raigambre es una de las vías que permitieron la expansión territorial novohispana por el noroccidente mexicano. Para ello, nos valemos de fuentes documentales y cartográficas primarias y su procesamiento a través de sistemas de información geográfica en su orientación histórica (SIG-H).

Authors: Toth Ariana 
Published: July 2019

This paper explores frst hand perceptions of Nicaraguan Miskitu women’s role in their local economy. Attention is paid to how economic practices have changed over time and whether change spurred by outside inﬂuences – such as corporate ventures and NGOs – have eroded the authenticity of an indigenous economy. Some historical economic practices are explored with a focus on the post-war economy and how political autonomy has affected women’s role. Surveys of Miskitu women obtained during feld research, with support from relevant literature, comprise the main source of information considered.
LA CONCEZIONE DEL TEMPO IN GUGLIELMO DI OCKHAM

Published: July 2019

A Física, desde Aristóteles, perguntou se sobre a noção de tempo. Guilherme de Ockham, ao tratar do assunto, critica a concepção desenvolvida por seus predecessores, fundamentada em uma leitura ontológica, enquanto ele opta por uma leitura baseada na empiria, o que o leva a considerar o tempo como um ente de razão. Com isso, abre caminho para submeter as categorias da temporalidade à análise lingüística

Quando me propus plasmar em música uma homenagem aos cem anos demorte de Friedrich Nietzsche, tinha em mente que era imprescindível que a composiçãodeveria conter, ainda que de forma simbólica, alguns elementos da filosofiado autor do Zaratustra. Considerando que esta forma de simbolismo de caráterjá abriga uma larga tradição na história da música ocidental, tendo seu ápice noEgmont de Beethoven, fui buscar não na pessoa de Nietzsche, mas em seus escritos, o impetus para a elaboração do meu trabalho.
Dissipative effect in liquid under exposure to low-frequency sound vibrations
Authors: Safonov V. A. , Lapa M. V. , Bykovsky Yu. M. 
Published: July 2019

The article describes the formation of dissipative structures in a liquid in a metal bowl when exposed to lowfrequency sound vibrations. The fluctuating volumes in a thick layer of liquid, that is, clusters of molecules, which make an oscillatory motion and with a loss of stability occupying a new position in the liquid, are investigated. An external synchronous effect on a group of molecules can lead to increasing oscillations and loss of stability not only inside the liquid, but these groups of molecules can leave the liquid through the free surface.Friction on the outer surface of a bowl made of a conductive bronze-containing alloy, which initiates the occurrence of sound vibrations, gives rise to the appearance of new structures in the fluid inside the bowl. The thickness of the liquid layer is about 50 mm. The coordinated addition of energy to the oscillating microvolumes of water allows them to release their potential energy and turn it into kinetic. Water droplets ejected vertically indicate the existence of intense vertical movement of individual volumes of fluid which create new structures and cells, like Benard cells, resulting from heating and vertical convection, but smaller sizes. The observed phenomenon is similar to “cold boiling”. Here, probably, the potential energy of the compressed water particles is released under the influence of external sound vibrations. Sound analysis was performed using an audio editor for several experiments of various lengths.In this work, the dissipative effect in a thick layer of liquid when exposed to low-frequency sound vibrations and the appearance of structures identical to Benard cells in limited volumes of water (and not in a thin layer) is first investigated. It should be assumed that the effect of sound vibrations can lead to blood turbulization and a change in the physical state of living organisms, which in terms of physical effect can be similar to the state of blood boiling with a rapid rise from the depth of the sea. The phenomenon can be used for the intensification of heat and mass transfer in heat exchange installations.
Genetic diversity of African clawless otters (Aonyx capensis) occurring in urbanised areas of Gauteng, South Africa

Published: July 2019

Genetic diversity is the basis of the evolutionary potential of species to respond to environmental changes. However, restricting the movement of species can result in populations becoming less connected which can reduce gene flow and can subsequently result in a loss of genetic diversity. Urban expansion can lead to the fragmentation of habitats which affects the ability of species to move freely between areas. In this study, the genetic diversity of the African clawless otter (Aonyx capensis) in Gauteng (South Africa) was assessed using non-invasive sampling techniques. DNA was extracted from spraint (faecal) samples collected along nine rivers and genotyped using 10 microsatellites to assess population structure and genetic diversity. Samples were grouped based on locality and by catchment to determine whether isolated subpopulations exist. Genetic diversity of A. capensis in Gauteng was found to be low (mean observed heterozygosity (Ho)=0.309). Analysis of genetic structure provides support for the otter populations being panmictic with high gene flow between populations from different rivers. Results from the study indicate that the movement of A. capensis is not affected by physical barriers in urbanised areas. However, because the genetic diversity of the species in the study area is low, these animals may not be able to cope with future environmental changes.
Significance:

Genetic structure analysis of the sampled Gauteng otter population indicates the population is panmictic; however, a low level of genetic diversity in this population has also been identified and may affect how the population copes with future environmental changes.
Physical restrictions in urbanised areas do not appear to be affecting movement of the species.
Sexualisation of Women in Nigerian Advertorial English Medium Bill Board
Authors: Opoola Bolanle Tajudeen , Awoniyi Folorunso, Emmanuel 
Published: July 2019

This paper surveys sexism in English, citing selected communicative instances in English medium billboards in Ile Ife, Osun State, Nigeria. The photographs and written inscriptions on the selected billboards depict the stereotypical representation of women as weaker species and exertion of men power over women. This was achieved through a critical discourse analysis of visual and verbal language discourses in ten randomly selected English medium billboards selected as sources of gathering data for this research. In Nigeria, billboards are meant for public announcements and advertisements. They also convey information about products and company services. Findings of this research among others reveal that there is asymmetrical power relation in terms of dominance and subordination between men and women as demonstrated by the portrayal of men in terms of physical attribute, such as strength, vigor, and a daring ability, as against the portrayal of women in terms of sex appealing, physical attractiveness as well as concerned with trivial, unserious and playful things. The study advocates for equal treatment of men and women without unnecessary sex differentiation.
Remote Sensing Identification of Possible Meteorite Impact Crater on Ciletuh, West Java

Published: July 2019

Ciletuh is a geopark area in West Java that has a semicircle-shaped cliff called mega-amphitheater. Morphogenesis of the amphitheater is still unknown. One possible cause is a meteorite impact that triggered a mega slump. This study aims to collect the evidence of meteorite impact. It has significant value for the geology of Indonesia since this region not yet has confirmed impact crater. In this research, image analysis from satellite remote sensing is used for identification of meteorite impact geomorphology. An analysis based on DEM unveils a ring morphology, a possible clue of an impact crater. The depression zone surrounded by a circular shape with an uplift area in the middle resembles characteristics of the complex impact crater. Meandering Ciletuh river indicates a compression due to a slump towards the southwest. Reconstruction of possible position toward the northeast (before slump deformation occurred) shows a clearer possible meteorite impact crater. A ground checking of identified structure proves that a bowl-shaped morphology found at the possible impact crater. Some steep dip structures have found, these might be due to an impact that causes the orientation of the structure to be upright. A stone that resembles the shatter-cone is found in the mí©lange area. The mí©lange is believed as a product of a sea trench million years ago. By using meteorite impact theory, it is also possible that the mí©lange is a kind of impact breccia. This feature adds uniqueness to Ciletuh as a geopark.

Published: July 2019

Liquid waste generated in large quantities in the palm oil mill has low pH and high organic content and its use as an organic amendment could offer an environmentally friendly management strategy. This pot experiment aimed to evaluate the impact of organic waste of the liquid waste from the palm oil mill and synthetic fertilizer on organic carbon and nutrients of an acid soil and soybean yield. The treatments consisted of no synthetic fertilizers, half recommended dose of synthetic fertilizers (0.5R), synthetic fertilizers as recommended 50 kg ha-1 Urea + 200 kg ha-1 SP-36 + 150 kg ha-1 KCl (R) and organic waste with doses of 0, 5, 10, 15 and 20 t ha-1. The experiment was arranged in a completely randomized design with a factorial pattern and three replications. The results demonstrated that there was no significant interaction on soil chemical characteristics by the addition of organic waste and synthetic fertilizers. However, organic waste addition increased soil pH, total organic C, labile organic C, humic acid C, total N, available P, exchangeable K, and cation exchange capacity (CEC), whereas synthetic fertilizer addition only increased available P and exchangeable K. Exchangeable Al was significantly reduced by organic waste while significant effect didn’t occur with synthetic fertilizers. The treatment of organic waste increased total organic C content by 7-24%. A larger sensitivity was indicated by labile organic C compared to total organic C and humic acid C so that labile organic C is a better indicator of alterations of soil organic C owing to organic waste treatment. The treatment of organic waste and synthetic fertilizers showed significant interactions on the dry weight of soybean seed, shoot, and root. The addition of synthetic fertilizers without organic waste increased the dry weight of the soybean seed, shoot and root by 133%, 133% and 140% respectively, while with the addition of 15 t ha-1 organic waste combined with synthetic fertilizer, enhancements by 262%, 261%, and 206% in the dry weight of seed, shoot and root were respectively found.
