Characteristics of almond leaf-ash cement stabilized lateritic soil
Authors: Eme D.B. , Ohwerhi K.E. 
Published: September 2020

The use of Almond leaf-ash for stabilization purposes has not been given consideration. This paper was thus aimed at evaluating the characteristics of almond leaf-ash for the essence of stabilizing lateritic soil. Sourced lateritic soil was divided into 3 components (unmodified soil sample, cement stabilized soil sample and almond leaf-ash cement stabilized soil sample). Almond leaves were calcined at 250°C and subjected to granulation process. Preliminary tests such as; sieve analysis, Atterberg’s limit and specific gravity tests were done on the unmodified soil sample for the purpose of classification. CBR tests were performed on the cement stabilized soil sample and on the almond leaf-ash cement stabilized lateritic soil sample. A model was developed using the Scheffe’s simplex theory with the cement component fixed at 10% of the dry lateritic soil. Results revealed that the soil was observed to be a Silty Clay soil (A-4) with Plasticity index of 9.24%, therefore requiring stabilization. CBR results for the developed trial mixes were greater than the 15.20% obtained for 10% cement stabilization showing that Almond leaf-ash significantly improved the CBR of the cement stabilized lateritic soil. The CBR model developed for the Almond leaf-ash cement soil also proved adequate from the verification test conducted using χ2 statistics.
Keywords: Almond Leaf Ash, stabilization, California Bearing Ratio, Scheffe’s theory, lateritic soil.

Published: September 2020

Las máquinas y los mecanismos que utilizamos en la actualidad, son el resultado del estudio y el perfeccionamiento de las máquinas simples desde la prehistoria. Su análisis desde el campo de la ingeniería mecatrónica es importante, ya que los conocimientos necesarios de esta ingeniería, comprenden muchas áreas, entre ellas la ingeniería mecánica. Dentro de la ingeniería mecánica se estudian los análisis dinámicos y cinemáticos de los mecanismos, por lo que, en el plan curricular de ingeniería en mecatrónica de la Universidad Estatal de Sonora, se integra la materia de diseño de mecanismos, como parte de la formación del estudiante de ingeniería en mecatrónica, en donde se entiende, que su estudio y su impacto en la vida cotidiana, puede estar inmerso por escenarios para el estudiante y egresado, que van desde la programación de un robot en el aula de clase, hasta la integración y puesta en marcha de proyectos y sistemas mecatrónicos en la industria. La materia de diseño de mecanismos se integra por tres elementos de competencia. Estos tres elementos tienen por objetivo utilizar los principios básicos del desplazamiento, aplicar análisis de velocidad y realizar análisis de aceleración en mecanismos de aplicación industrial, por lo que se requiere, dentro de las competencias específicas del curso, el uso de software especializado para el análisis cinemático de los mecanismos. El objetivo de esta investigación es analizar el desplazamiento, la velocidad y la aceleración de diferentes mecanismos, con un enfoque de las competencias requeridas por la materia de diseño de mecanismos de ingeniería en mecatrónica de la Universidad Estatal de Sonora, para demostrar el potencial de aplicación en entornos de enseñanza-aprendizaje, como una simulación del campo profesional, mediante el uso del software Motion de Solidworks y CATIA V5. La metodología empleada para esta investigación, se plantea en tres puntos: 1) selección de mecanismos a analizar, 2) diseño de mecanismos mediante CATIA y 3) simulación con software Motion.

Esta pesquisa objetivou analisar o conceito de infância na formação inicial nos cursos de Licenciatura em Educação Física, a partir dos indicadores contidos nas ementas dos cursos das Instituições de Ensino Superior (IES) públicas do estado do Paraná. Utilizou-se dos pressupostos da pesquisa qualitativa do tipo documental, com o intuito de apresentar as interlocuções percebidas sobre o reconhecimento da infância no processo formativo. Os resultados indicam a escassez de disciplinas que tratem das questões da infância; sendo evidenciado que o conceito está sendo associado a fases e etapas de desenvolvimento motor, atrelados à perspectiva desenvolvimentista. Como resultado, pode-se desprender que os currículos de formação inicial, apresentam fragilidades nas múltiplas interjeições com os campos antropológicos e sociais, evidenciando uma lacuna conceitual no processo de formação docente dos cursos investigados.
Civic Engagement and Opinion of Politics at a High School Level
Authors: Cruz Diana Isabel , Everson Brian 
Published: September 2020

"At one point or another, young people will become the majority that can vote compared to baby boomers and other demographics. Therefore it is important to address the political efficacy and engagement of youth, because they will be-or already are- making change. However, this is by no means a new idea. There have been studies in the past, however, this in particular will be addressing the question of, “To what extent do ethnicity, participation in political organization, party affiliations, and civic engagement level factor into students opinions of politics and their civic engagement?”"
After collecting 220 responses, students ethnicity, political affiliation, their level of civic engagement, and whether they were involved in a political organization was taken into account to determine the effect on their opinions of politics and how they interacted with government. It was found that involvement in a political organization was the greatest factor when looking at the data quantitatively and qualitatively.
The Effect of Antibiotics on the Respiration of Microorganism in Northern Ohio Rivers
Authors: Gonia David Patrick , Talarczyk Patricia 
Published: September 2020

This experiment was conducted for the purpose of inquiring how the concentration of antibiotics, specifically Amoxicillin and Cephalexin, would affect the productivity of aquatic microorganisms within Northeastern Ohio rivers. In acknowledgment of the growing concerns over agricultural pollution, the study was devised to increase current knowledge of how the presence of antibiotics could affect aquatic microorganisms other the well-documented creation of antibiotic-resistant bacteria. In order to achieve the research goal, water was collected from a Northeastern Ohio river and then tested with various amounts of antibiotics. Over the following five days, the concentration of dissolved oxygen was measured which was used to calculate the overall rate of respiration of the sample. The overall respiration rates of the samples with Amoxicillin were 0.0369 mg/L·hr (milligram per liter per hour) with no antibiotics, 0.835 mg/L·hr with 250 mg, 1.16 mg/L·hr with 500 mg, and 0.951 mg/L·hr with 750 mg. The samples with Cephalexin yielded rates of 0.963 mg/L·hr with 250 mg, 0. mg/L·hr with 500 mg, mg/L·hr with 750 mg. These yielded R-values of 0.694 and 0.788 respectively.. This means that the null hypothesis was rejected, thus showing a statistically significant correlation. However, the alternate hypothesis was not supported as a positive correlation between the respiration rate and antibiotic concentration was shown.
BROCKHAMPTON: Social Advocacy and Diversity in Rap Music
Authors: Opara Ndidi 
Published: September 2020

BROCKHAMPTON is a diverse, multiracial rap group that has recently garnered rapidly increasing popularity and influence in the rap industry. Because of this, I wanted to determine if the popularity of the group’s SATURATION trilogy was affected by the content matter they addressed and how that intersected with the American color line in music marketing. With the research question, “To what extent does the race of a BROCKHAMPTON member and the advocacy they utilize, whether it be pro-social or anti-social advocacy examined through the usage of corresponding social themes, influence the popularity of a given song from BROCKHAMPTON’s SATURATION trilogy?”, this study found that it was influenced to a minor extent, with no strong correlation found between race and social themes discussed, or between popularity and the dominant thematic category of a song.
Unwanted
Authors: Marinari Maddalena 
Published: September 2020

In the late nineteenth century, Italians and Eastern European Jews joined millions of migrants around the globe who left their countries to take advantage of the demand for unskilled labor in rapidly industrializing nations, including the United States. Many Americans of northern and western European ancestry regarded these newcomers as biologically and culturally inferior--unassimilable--and by 1924, the United States had instituted national origins quotas to curtail immigration from southern and eastern Europe. Weaving together political, social, and transnational history, Maddalena Marinari examines how, from 1882 to 1965, Italian and Jewish reformers profoundly influenced the country’s immigration policy as they mobilized against the immigration laws that marked them as undesirable. Strategic alliances among restrictionist legislators in Congress, a climate of anti-immigrant hysteria, and a fickle executive branch often left these immigrants with few options except to negotiate and accept political compromises. As they tested the limits of citizenship and citizen activism, however, the actors at the heart of Marinari’s story shaped the terms of debate around immigration in the United States in ways we still reckon with today.
Stirrings
Authors: Povitz Lana Dee 
Published: September 2020

In the last three decades of the twentieth century, government cutbacks, stagnating wages, AIDS, and gentrification pushed ever more people into poverty, and hunger reached levels unseen since the Depression. In response, New Yorkers set the stage for a nationwide food justice movement. Whether organizing school lunch campaigns, establishing food co-ops, or lobbying city officials, citizen-activists made food a political issue, uniting communities across lines of difference. The charismatic, usually female leaders of these efforts were often products of earlier movements: American communism, civil rights activism, feminism, even Eastern mysticism. Situating food justice within these rich lineages, Lana Dee Povitz demonstrates how grassroots activism continued to thrive, even as it was transformed by unrelenting erosion of the country's already fragile social safety net.
Using dozens of new oral histories and archives, Povitz reveals the colorful characters who worked behind the scenes to build and sustain the movement, and illuminates how people worked together to overturn hierarchies rooted in class and race, reorienting the history of food activism as a community-based response to austerity. The first book-length history of food activism in a major American city, Stirrings highlights the emotional, intimate, and interpersonal aspects of social movement culture.
Speaking of Feminism
Authors: Seidman Rachel F. 
Published: September 2020

From the Women's Marches to the #MeToo movement, it is clear that feminist activism is still alive and well in the twenty-first century. But how does a new generation of activists understand the work of the movement today? How are their strategies and goals unfolding? What worries feminist leaders most, and what are their hopes for the future?
In Speaking of Feminism, Rachel F. Seidman presents insights from twenty-five feminist activists from around the United States, ranging in age from twenty to fifty. Allowing their voices to take center stage through the use of in-depth oral history interviews, Seidman places their narratives in historical context and argues that they help explain how recent new forms of activism developed and flourished so quickly. These individuals' compelling life stories reveal their hard work to build flexible networks, bridge past and present, and forge global connections. This book offers essential reading for anyone seeking to understand the contemporary American women’s movement in all its diversity.
Trends in national and regional scale drought in New Zealand
Authors: Kingston Daniel G. , Treadwell Eleanor J. 
Published: September 2020

Abstract. Drought is a critical natural hazard in New Zealand,
affecting both agricultural production and hydro-electric generation.
However, the detection and characterisation of drought events are
complicated by the range of different drought metrics available. Here,
time-series variation in drought is investigated for New Zealand using two
commonly used indices: the Standardized Precipitation Index (SPI) and the
Standardized Precipitation Evapotranspiration Index (SPEI). Both the SPI and
SPEI are calculated from WATCH Forcing ERA-Interim data (a bias-corrected
version of ERA-Interim). Analyses are based on the proportion of New Zealand
experiencing at least “moderate” drought (i.e. index values at the threshold
of −1 or lower). There is no statistically significant difference in area in
drought between the two indices averaged over the time series, and no
national-scale trends in drought occurrence are identified. However, a
statistically significant trend of divergence between the SPI and SPEI is
present when examining drought at moderate spatial coverage (10 % and
20 % coverage based on SPEI), with the SPEI showing increasingly greater
drought coverage. These typically become more apparent either as a major
drought event is building or terminating. As such, the SPEI generally
indicates an extended duration (rather than higher peak extent) of drought
events. The spatial expression of the largest SPI-SPEI differences reveals
“hotspots” in terms of both average and divergent trends in drought extent,
results which are reflected in a regional drought analysis using a cluster
analysis of the SPI and SPEI area in drought. In particular, SPEI drought
coverage is greater in the South Island east coast and central/southwestern
North Island regions. Conversely, SPI drought extent is greater in the
eastern North Island. Overall, the differences and similarities in drought
extent between the SPI and SPEI can be linked to the highly varied nature of
New Zealand climate, with the instances of greater SPEI drought located in
regions of driest and most continental climate.
Climate change impact on hydrological characteristics and water availability of the Mountain Pamir Rivers
Authors: Normatov Inom , Normatov Parviz 
Published: September 2020

Abstract. Results of monitoring accumulated snow cover in upstream areas of the Transboundary Pyanj River (Central Asia) are presented. It is found that the formation of the snow cover and the spatial distribution of atmospheric precipitation in the Mountain Pamir is determined by the orography of the terrain. Orography influences air mass movement in mountain areas, which contributes in different climatic zones to a shift in periods when the maximum amount of snow is falling. Completely different scenarios for the development of meteorological variables in the western and eastern parts of the Gunt River Basin were found, due, firstly, to the influence of the mountainous area orography and, secondly, to the penetration of various air masses. It is observed that in the western part of the basin the average annual precipitation remained almost unchanged over the period 1944–2014, whereas there is a decreasing trend in the eastern part. Assessment of the climate change impact on the formation of the Gunt River water flow was made by comparing the trend in the change of discharge using data from two observation periods 1940–1970 and 1986–2016. Calculations show a decrease of the Gunt River discharge by 5 % over a period of more than 70 years. The influence of climate warming on the river flow is indicated by comparison of river hydrograph in two periods 1940–1970 and 1986–2016. The hydrograph of the Vanch River in the earlier-mentioned periods shows a shift in the maximum of the monthly discharge towards the left, indicating an earlier melting of snow and glaciers in the upstream regions of the river and a significant increase in discharge in the period 1986–2016.

Published: September 2020

Abstract. In last decades, the impact of climate change started to appear in the semi-arid regions of the Mediterranean Basin. The severity and frequency of drought events in Northwestern Algeria have affected water resources availability and agriculture. This study aims to evaluate the temporal evolution of drought events characteristics, such as drought duration, frequency and severity, of the Beni Bahdel Dam catchment, Northwestern Algeria. Drought characteristics have been derived from the Standardized precipitation index (SPI) computed for the period from 1941 to 2100 using precipitation data from observations and simulations of the regional climate model RCA4 (Rossby Centre Atmosphere model, version 4). The RCA4 model was forced by the global circulation model MPI-ESM-LR under two
Representative Concentration Pathways (RCPs) scenarios. The ability of the
model simulations was firstly assessed to reproduce the drought
characteristics from observed data (1951–2005). Then, future changes in
drought characteristics over the twenty-first century were investigated
under the two scenarios (RCP4.5 and RCP8.5). Results show an amplification of drought frequencies and durations in the future under the RCP8.5 scenario.
Climate change impact on water resources in Klong Yai River Basin, Thailand
Authors: Ekkawatpanit Chaiwat , Pratoomchai Weerayuth , Khemngoen Chatchapol , Srivihok Patchanok 
Published: September 2020

Abstract. There is a 95 % scientific consensus that human
activities contributed to climate change and altered hydrological processes.
This study focused on a regional scale climate change impact assessment on
water resources in the Klong Yai River basin in Thailand using multiple
Global Climate Models (GCMs) under 3 scenarios of greenhouse gas emission
called the Representative Concentration Pathway (RCPs), i.e., low (RCP2.6),
intermediate (RCP4.5), and high (RCP8.5) scenarios. According to the
projections, surface air temperature will increase relative to the reference
period (1991–2000). Maximum surface air temperature is projected to increase
around 0.3–1.35 ∘C. Precipitation in the near future (2017–2026
and 2027–2036) shows an increasing trend. The projected precipitation and
temperature were used in the SWAT model for the Klong Yai River basin in
order to assess the amount of inflow into reservoirs under the climate
change conditions. Despite the future projections still have an uncertainty,
but it is useful as a guideline for managing of our water resources and
planning.
Catulo traducido por José Ángel Valente. 'Versión de Catulo' en 'Nada está escrito', seguido de 'Anales de Volusio' en 'El inocente'
Authors: Valenciano Adrián 
Published: September 2020

La aproximación a otros autores desde la práctica de las versiones ha sido un modo de escritura llevado a cabo por numerosos escritores como ejercicio literario y diálogo poético con la tradición. En el presente artículo se plantean los siguientes objetivos; en primer lugar, poner en valor el recurso de la versión empleado por un José Ángel Valente en sus más tempranos inicios literarios a partir del poema “Versión de Catulo”, incluido en su poemario de juventud Nada está escrito (1952-1953), y publicado póstumamente; en segundo, resaltar la reiterada práctica de la versión desde el estudio del poema “Anales de Volusio”, una recreación inspirada en el carmen XXVI del poeta latino, incluida en el séptimo poemario de Valente, El inocente (1967-1970). En ambos casos se observa cómo pasa de la lectura del original a la traducción más libre.

Published: September 2020

A new phylogenetic hypothesis is proposed for the relationships among the species within the genus Docosia Winnertz, 1863, based on a combined analysis of five DNA markers (28S, ITS2, COI, COII and CytB). Five new species are described, Docosia anatolica Ševčík sp. nov. from Turkey, D. japonica Kurina sp. nov. from Japan, D. peloponnensis Ševčík sp. nov. from Greece, D. svanetica Kurina sp. nov. from Caucasus and D. polyspina Kurina sp. nov. from the Russian Far East. New country records of the following species are presented: D. diutina Plassmann, 1996 (Turkey), D. flavicoxa Strobl, 1900 (Georgia), D. gilvipes (Haliday in Walker, 1856) (Georgia), D. kerkini Kurina & Ševčík, 2011 (Bulgaria), D. moravica Landrock, 1916 (Georgia), D. pannonica Lastovka & Ševčík 2006 (Georgia) and D. rameli Kurina & Ševčík, 2011 (Slovakia).
Barthes and Commissioned Writing
Authors: Compagnon Antoine 
Published: September 2020

Roland Barthes constantly complained about being overwhelmed with requests and importunities; people were always sending him texts to read, and strangers would write or phone for appointments, articles, and advice. What he called the burden of administration (‘la gestion’) took up as much of his time as creative work. And he entertained the dream of a Vita Nova, liberated from supplications. The decision of ‘15 April 1978’, recorded in La Préparation du roman, was a revelation: henceforth, all of his life would be concentrated around literature – the novel – and he would switch to an ex-directory phone number. Yet Barthes, at the same time, loved the pressure of demands; he was addicted to the flow of requests and could not work without the stimulus of commissions and deadlines. In fact, as he well knew, most of what he produced started out as a commission (whether a ‘demande’ or a ‘commande’), right from the very first articles in Combat and his many contributions to book clubs. All through his life the pressure of writing for journals never ceased: Existences, Esprit, Théâtre populaire, Lettres nouvelles, L’Observateur or France-Observateur; later Critique, Communications, Tel Quel… This is the paradox to be explored in this chapter.
