Published: September 2020

Ngo River in Gboko, Benue State, Nigeria which serves as a source of water for domestic and agricultural purposes for the agrarian community receives effluent from Dangote Cement factory. Physicochemical analysis of the effluent outfall and water samples collected along 15 km of the river stretch were carried out in dry and wet seasons respectively. The results obtained were compared to FEPA, WHO and NESREA Standards. For effluent outfall, Temperature, TDS, pH, EC, BOD, COD, sulphate and chloride, total hardness, calcium and magnesium, were found to be within the FEPA standards, while TSS, turbidity, and nitrate, were above the standards. Along 15 km study reach, mean temperature range of 32.4oC to 29.0oC, a TSS of 224 mg/l to 218 mg/l, a turbidity of 45 NTU to 42 NTU, and DO of 1.6 mg/l to 1.2 mg/l were obtain during the dry season, while mean temperature range of 36.8oC to 36.6oC, a TSS of 255 mg/l to 252 mg/l, turbidity of 176 NTU to 168 NTU, and DO 2.8 mg/l to 2. 6 mg/l were obtained during the wet seasons. These results were above WHO and NESREA temperature (25oC drinking water), TSS (30 mg/l domestic and 100 mg/l agriculture) water use, 5 NTU turbidity, and 5mg/l to 7.5mg/l DO standards. The effluent is relatively treated and effects such as aquatic depletion in the environment, decreased soil pore size and decreased permeability in the use of the water for irrigation, and water related diseases are not ruled out.

Published: September 2020

Water current modelling and prediction techniques along coastal inlets have attracted growing concern in recent years. This is largely so because water current component continues to be a major contributor to movement of sediments, tracers and pollutants, and to a whole range of offshore applications in engineering, environmental observations, exploration and oceanography. However, most research works are lacking adequate methods for developing precise prediction models along the commodore channel in Lagos State. This research work presents water current prediction using Artificial Neural Networks (ANNs). The Back Propagation (BP) technique with feed forward architecture and optimized training algorithm known as Levenbergq-Marquardt was used to develop a Neural Network Water Current Prediction model-(NNWLM) in a MATLAB programming environment. It was passed through model sensitivity analysis and afterwards tested with data from the Commodore channel (Lagos Lagoon). The result revealed prediction accuracy ranging from 0.012 to 0.045 in terms of Mean Square Error (MSE) and 0.80 to 0.83 in terms of correlation coefficient (R-value). With this high performance, the Neural network developed in this work can be used as a veritable tool for water current prediction along the Commodore channel and in extension a wide variety of coastal engineering and development, covering sediment management program: dredging, sand bypassing, beach-contingency plans, and protection of beaches vulnerable to storm erosion and monitoring and prediction of long-term water current variations in coastal inlets.

Assessment of cement concrete partially replaced with polystyrene and plantain peel ash
Authors: Aderinola O.O. , Yusuf Y. , Omotayo O.O.
Published: September 2020

This study assessed the effect of partial replacement of cement with plantain peel ash (PPA) and Polystrene (POL) on the compressive strength of concrete as a means of managing waste. Concrete specimens were prepared with a mix ratio of 1:2:4 (cement: sand: granite) water/cement ratio of 0.6, thereafter cement was partially replaced with PPA, POL and PPA/POL in increasing percentages of 5, 10, 15 and 20% by weight. Physical, chemical and microstructural analyses were also conducted on the aggregates and materials used. Workability of the concrete specimens was observed to improve upon addition of PPA and POL separately but not with blended PPA/POL while compressive strength decreased with addition of the three compounds. The observed results can be attributed to the lack of sufficient cementitious properties in the materials, and hence, the study discourages the use of these materials as they do not significantly improve concrete strength.

La didáctica tiene una relevancia muy importante en el proceso de enseñanza-aprendizaje, sobre todo dentro del aula y en campo. Dentro de las herramientas didácticas podemos encontrar un número extenso de posibilidades, desde metodologías para solución de problemas básicos, hasta la implementación de aulas virtuales remotas para la gestión del aprendizaje o el uso de laboratorios, por mencionar algunos. Otro tipo de herramientas didácticas de alto valor en el área de la enseñanza-aprendizaje, son los equipos didácticos, que ayudan al profesor y al alumno, a explicar y comprender fenómenos, que, de forma analítica o conceptual, no se describen por si solos, por ejemplo, algunos efectos vinculados a la mecánica de fluidos, sobre todo los que se efectúan en sistemas cerrados. Esta investigación tiene por objetivo, diseñar y fabricar un equipo didáctico digital para la simulación y análisis de flujos incompresibles; específicamente agua, basándonos en la hipótesis de que se pueden interpretar variables y factores de la mecánica de fluidos a valores cuantitativos y cualitativos, mediante el procesamiento de dispositivo Arduino Uno y el uso de sensores electrónicos. Para poder demostrar la hipótesis se realizó una metodología compuesta por cinco etapas. En la etapa uno, se realizó un marco teórico referente a las ecuaciones y variables de mecánica de fluidos para la solución de velocidad y turbulencia. En la etapa dos se seleccionaron los componentes hidráulicos, electrónicos y de sensado. En la etapa tres se realizó un diseño digital tridimensional del tablero.  En la etapa cuatro se realizó la integración del sistema hidráulico. En la etapa cinco se integraron los sistemas de control. En la etapa seis se realizó la programación de los sensores y pantallas en software Arduino, y en la etapa siete se integró todo el equipo didáctico.  Como resultado se obtuvo un equipo didáctico digital para la medición de velocidad y turbulencia, con un margen de error de entre 3 y 5% respecto a los cálculos teóricos.

Resumen

 

La ganadería bovina en México, significa una de las actividades del sector agropecuario más importantes por la oferta que se realiza con los productos cárnicos, así como su participación en la balanza comercial del país.

Por su parte, la ganadería de Sonora es una de las actividades económicas de mayor tradición y que da identidad al Estado. Siendo una de las principales entidades productoras de carne bovina a nivel nacional y reconocida por la alta calidad en sus productos.

En el Estado de Sonora los ganaderos prefieren engordar y exportar ganado en pie, ya que se ha convertido en una actividad muy atractiva dado los precios obtenidos y las condiciones comerciales actuales. Sin embargo, con esta práctica están transfiriendo la creación de valor a los importadores en Estados Unidos. Mediante esta investigación el productor de ganado en pie podrá conocer las características y preferencias de los consumidores nacionales y con esto determinar qué tan atractivo puede resultar el mercado mexicano para el consumo de sus productos y crear valor en suelo nacional para esta industria.

En este estudio se les preguntó a los comercializadores de carne de res de la ciudad de Navojoa, Sonora qué factores influyen al momento de decidir la compra de carne de bovino. Se encontró que estos prefieren la carne nacional sobre la importada, son consumidores con una alta fidelidad a su proveedor, privilegian la calidad, la higiene, el sabor, la variedad antes que el precio.

Se espera que con este estudio los productores de reses para exportación, consideren la opción de crear valor aquí mismo en el país, obteniendo mejor rentabilidad y creando nuevos puestos de trabajo. Asimismo, el gobierno al apoyar,  generaría mayores contribuciones tributarias para la nación.

Particulate Matter Triggers for Pediatric Asthma
Authors: Chami Batoul , Johnson Elizabeth , Courage J. Mike , Danielson-Francois Serge
Published: September 2020

The exposure of particulate matter on children, ages 1-18, is considered in this paper using a quantitative research approach. Utilizing foundational and seminal sources, this is a review of asthma and its triggers, and particulate matter, specifically ultrafine particles with a dimension of less than or equal to 100 nanometers (nm). An interest sparked with the effect of these ultrafine particles and their possible ignition of asthma. A troubling area was a lack of information on what may cause a greater link when exposed to these ultrafine particles: an ambient/indoor environment or an outdoor/non-ambient environment. This posed a significant concern because even though both environments may lead to asthma, the lack of information was not evident and not uninformed. To conduct this study, a systematic review occurred using a statistical program. Data was accumulated from multiple sources that tested for either an association of pediatric asthma and particulate matter with an outdoor exposure or an indoor exposure. Analyses were ran and statistical evidence resulted in a greater association in an indoor environment. The variables accounted for were odds ratio, confidence intervals and their limits, the setting of the tests run within the research and the exposure of the particulate matter.
The Relationship between Hamstring Flexibility and Level of Competitive Irish Dancers
Authors: Motta Rosalia , Talarczyk Patricia
Published: September 2020

The purpose of this study was to investigate the potential relationship between hamstring flexibility and competitive level of Irish dancers. Since the premier of Riverdance in 1994, Irish dance has grown in population and has geologically spread to locations previously unassociated with Irish culture. Resulting from these changes has been the establishment of more and larger competitions, as well as increased athleticism in the dance form. This study followed a quasi-experimental approach, and dancers volunteered to participate. Participants were first asked verbal questions for secondary data collection and data on performance level. Hamstring flexibility was then measured using the Straight Leg Raise (SLR) test for analysis. The data support the conclusion that higher level Irish dancers have higher hamstring flexibility than lower level dancers. Irish dancers seeking to advance into higher competition levels may use this information to incorporate more flexibility building into their training. Likewise, Irish dance instructors may devote more instruction time to assisting their students in building their hamstring flexibility efficiently and properly. Future researchers may investigate similar studies with other physical aspects, such as flexibility in the quadriceps. Alternatively, researchers may investigate the extent to which Irish dance adjudicators seek out high hamstring flexibility in the dancers they judge in comparison to more traditional aspects of Irish dance.
The effects of cleaning solutions on bacteria concentration on hospital wheelchairs
Authors: Knapp Erin
Published: September 2020

To what extent does the concentration of bacteria located on hospital wheelchairs vary based on the cleaning solution used between patient transport? The purpose of this study was to investigate the cause of HAIs [Hospital Acquired Infections] in hospital environments and determine the best cleaning method of wheelchairs in hospitals. The method was to swab the seats and handles of wheelchairs before and after cleaning them while wearing gloves in comparison to no gloves with varying strengths of cleaning solutions, plating the swab, and allowing the bacteria to be incubated and grow in an incubator. Then, every day for 10 days, plates were measured on a piece of graph paper to record growth. A one-way ANOVA was calculated for the effectiveness of the various cleaners and a p-value of 0.6597 was achieved and a t-test was performed to compare the values of gloves versus no gloves and a p-value of 0.2216 was calculated. The p-values were not significant at 0.05. Overall, wearing gloves while cleaning showed to have a slight positive impact on the overall cleanliness but was not statistically significant, and the highest strength wipes inhibited bacterial growth most often. Hospital protocol for the cleansing of wheelchairs between patient use should be updated to the use of gloves and high strength wipes to stop the spread of bacterial infections to patients.
The Impact of Food Allergy Training on a Teacher’s Self-Efficacy when Managing Food Allergic Students
Authors: Cook Paige , McDonough Meghan
Published: September 2020

Food allergy training for teachers remains an important, but commonly overlooked, aspect of education as millions of children have been diagnosed with food allergies. Therefore, it is pertinent teachers receive food allergy training that is most beneficial in growing a teacher's understanding for teachers to be best suited in correctly helping food allergic students. Four food allergy training methods: hands-on in-person (actual handling of epinephrine), non-hands in-person, group video, and individual video, and their effects on the self-efficacy of participants is the focus of this study. Teachers were contacted from within the city of Chicago, both public and private, and from a mixture of food allergy training methods and were administered an online survey which asked questions pertaining to their food allergy knowledge, perception, and self-efficacy. Participants were given statements to which they would respond on a five-point Likert scale, scored using a chi-square test. Ultimately, the hypothesis that teachers who engaged in hands-on in-person would showcase higher levels of self-efficacy, due to higher levels of engagement, was not supported. While several statements proved significant after data analysis, there was not enough significance to prove a meaningful relationship between the self-efficacy and training method.
DAVE: Optimizing Wasabi Agriculture Through Automation and Successive Approximation
Authors: Lefebvre Jayden
Published: September 2020

Wasabi agriculture continues to predominantly rely on traditional practices. There currently exists an abundance of botanical literature surrounding the optimization of the wasabi growth environment to increase crop quality, however this research is detached and independent. Considering the recent rise to prominence of cyber-agriculture technology, its use in further optimizing the wasabi growth environment should be considered. By designing and constructing two wasabi-oriented food computer prototype iterations, uniting and synchronizing the results of existing wasabi optimization research, and growing Wasabia japonica plants inside these food computers, it was found that despite the widely reported difficulty of traditional wasabi farming, the crop is a strong contender for novel cyber-agriculture: the plant tissues showed a 69.3% increase in flavour compound (allyl isothiocyanate) concentration overall. The plants also exhibited a 74.7% decrease in overall plant mass, pointing to a well-documented phenomenon dubbed the “dilution effect” present in intensive agriculture. Overall, given future design improvements and more extensive data collection, there exists the possibility to revolutionize wasabi agriculture by engineering cyber-agriculture solutions tailored to wasabi growth.
The Legend of Zelda and the Portrayal of Women in Gaming History
Authors: Prom Norachase
Published: September 2020

This paper aims to analyze the change in the cultural depictions of female characters in video gaming history through the developments of the character Princess Zelda over the course of ten games from The Legend of Zelda Series, spanning from 1986 to 2017. The ten games were divided into three categories by the developers that managed the series, games by Shigeru Miyamoto (1986 - 1998),Takashi Tezuka (2002 - 2009), and Eiji Aonuma. (2008 - 2019), respectively. Under each developers' tunure, Princess Zelda's portrayal was altered to adapt the cultural view of women during their time. The results of this literary analysis was that Princess Zelda’s constantly evolving depiction represents two events in the gaming industry: the transition from an eastern perspective to a western perspective regarding the view of women in the gaming industry, and the changing demographics in the video game market to more female consumers.

General Braxton Bragg inherits a demoralized and ragged army. To deter desertions and improve the professionalism of his troops in general, Bragg implements stricter rules and punishments, which earn him a poor reputation among his subordinates. Expecting Kentuckians to rise en masse and join the southern cause, Bragg marches into Kentucky hoping to secure Confederate control of the state. Ultimately, the number of Kentucky natives that join the army is unimpressive, Bragg fails to secure the state, and he and his army return to Tennessee. Later, General Joseph E. Johnston is placed in charge of the newly formed Western Department, which includes a department in east Tennessee lead by Edmund Kirby Smith, Bragg’s department in Middle Tennessee, and John C. Pemberton in Mississippi. Johnston is skeptical of his department’s future success due to lack of troops, transportation issues, and what he considered faulty strategy suggested by President Davis and military officials.
Confrontation

After realizing that he was unpopular, Bragg asked his officers if he was ill-suited for his position and should consequently step down. The answer was overwhelmingly yes. He also asked them whether there were men in their ranks who leaked negative information about him to the press. They falsely responded in the negative. President Davis sent Joseph Johnston to Tullahoma to investigate the leadership crisis in the Army of Tennessee and possibly take command of the army. He refused to do the latter. In the end, Bragg did not resign; instead he attempted to remove his opponents. He succeeded in some instances but was unable to expunge his perceived most hostile critics, Cheatham and Breckinridge. Similarly, Polk and Hardee were not punished. The most substantive thing that came of the animosity between the corps commanders and Bragg was a breakdown in friendly relations.
Missed Opportunities

After the loss of middle Tennessee, The Army of Tennessee was scattered around the state. The Federalists then began making offensive moves. The Confederates were unable to predict Rosecrans’s strategies. On September 1, Bragg was notified that two-thirds of the Federal army was south of Chattanooga and moving toward Trenton. He had thought only calvary and a few small infantry forces were on his left. Historians blamed this failure of communication on Wheeler, who poorly managed his forces. Bragg and other officers came up with a plan too late, and Chattanooga was vacated. Plans were then made to attack Federalists in McLemore’s Cove, but Bragg’s subordinates failed to execute plans properly, and the Federalists escaped. Davis later sent reinforcements to the Army of Tennessee.
The Medical Corps

After the Battle of Murfreesboro, thousands of wounded soldiers flooded hospitals from Chattanooga, Tennessee to Atlanta, Georgia. Makeshift hospitals were set up in all useable buildings like churches. Additionally, after Murfreesboro many men in the Army of Tennessee fell ill with diarrhea. The cause was likely inadequate drainage of camps, contaminated drinking water, and unhealthy foods. Men also suffered from general “fevers” brought on by exposure to the elements. By September 1863, the Army of Tennessee had increased its bed capacity to 7,782 with 32 facilities. Dr. Samuel H. Stout was most responsible for the army’s hospital system. Edward A. Flewellen served as medical director of the army. The battle of Chickamauga resulted in double the injuries than the medical corps had estimated. Consequently, men had to be treated in tents, open fields, and other inadequate locations. Transporting wounded to hospitals was a logistical nightmare as trains had limited space. In the weeks after Chickamauga, thousands became seriously ill. After Chickamauga, Stout had bed capacity increased to 12,000 and organised a reserve medical corps.
Logistics

Feeding the men and animals of the Army of Tennessee required thousands of tons of food to be transported by wagon, train, and steamboat. In addition to transportation, feeding the army proved difficult because its food supply had to be shared with other branches of the Confederate Army. Soldiers often complained of monotonous rations.
Capt. Moses H. Wright’s Atlanta Arsenal supplied most of the Army of Tennessee’s ammunition. However, the Atlanta Arsenal struggled to keep up with demand, and army personnel complained about defective equipment. An attempt to uniformly equip soldiers with weapons ultimately failed.
The Atlanta Quartermaster Depot made shoes exclusively for the Army of Tennessee. This depot also made clothing for the army. Shortages of clothing and shoes persisted. The Army of Tennessee relied on the Western & Atlantic railroad to transport materials from Atlanta, which at times did not have enough engines to provide adequate supplies. Overall, the Army of Tennessee had industrial assets, but an inadequate transportation system led to meat shortages, which decreased morale and resulted in desertions. Additionally, the poor transportation system prevented additional troops from reaching the disastrous Battle of Chickamauga.
Struggle for Atlanta

Beginning in May 1864, the Army of Tennessee engaged in several confrontations with Sherman’s Union forces. At the Battle of New Hope Church, the Union sustained 1,732 casualties while the Confederates only sustained 448. The battle was dubbed “The Hell Hole” because of the gruesome sight of so many dead Union soldiers. In a subsequent battle, Sherman lost 1,600 and Cleburne’s division only lost 500. Despite these victories, Johnston and the Army of Tennessee were gradually pushed back to Atlanta. Officer Hood replaced Johnston after Davis and other military officials expressed displeasure at Johnston’s constant retreating and lack of plan for defending Atlanta. After several engagements throughout August and July, the Confederates lost Atlanta.
A Pathway to Victory

There were several reasons the Army of Tennessee kept fighting despite demoralizing losses. Some considered the war a fight to the death; that is, being brought back into the Union was not an option. Others hoped for foreign intervention, but most knew this was unlikely. Some found comfort in rumors of international recognition. Others believed the war would bankrupt the North. The re-election of Republican Abraham Lincoln ended hopes that a Democrat in office would end the war and grant the south its wishes. In general, the Army of Tennessee believed that they could keep fighting until the North was too war-weary to continue. There was no talk of surrender.
Conquered

Morale plummeted after the loss of Atlanta, though Davis came to visit the Army of Tennessee and was well received. Hood began his North Georgia Campaign in late September. His plan was to destroy the Western & Atlanta railroad to cut off Sherman’s supply line and then have the Army of Tennessee attack from the rear. The army succeeded in destroying the railroad and moved on to Tuscumbia, Alabama. Next, Hood planned to go to Nashville, march into Kentucky, threaten Cincinnati, and recruit men along the way. Ultimately, the Tennessee campaign failed. George Thomas’s Union forces defeated the Army of Tennessee at Nashville and they were forced to retreat to Mississippi. The Army of Tennessee surrendered on April 26, 1885, 17 days after Robert E. Lee.

Faiz, Love, and the Fellowship of the Oppressed
Authors: Hyder Syed Akbar
Published: September 2020

Faiz Ahmed Faiz was one of modern South Asia’s most renowned poets, his work a favorite not only of first Indian Prime Minister Jawaharlal Nehru, but of millions. Over the course of his later life, he had to navigate the complex realities of partition, a condition that refracted the larger bi-polar Cold War world in which he found himself. He raised his voice against illegal occupations, confronted religious charlatans, and protested the rule of military dictators. He was incarcerated in Pakistan, the country he embraced, while simultaneously impacting popular culture in neighboring India. He received the Soviet Union’s highest literary award even as he was once denied a visa to the United States. Through all of this, Faiz spoke of ways in which to rise from the parochial human to the universal being. This essay will focus on the modes of Faiz’s discourse that connect his present with liberatory moments of the past; in turn, this connects his personal struggle with those of everyday people, humanity writ large. The paper will draw from discourses of world citizenship that are embedded in Islamic mysticism (Sufism) to show how these discourses helped frame Faiz’s outlook and his critique of a world defined by negating opposites.
Bertrand Russell in Bollyworld
Authors: Kaur Raminder
Published: September 2020

The chapter considers the scope of film to act as what is described as a ‘docu-drama-ment’ for conveying affective engagements with political history. It does so with a focus on unique incidents in the history of Indian popular cinema with the example of the film, Aman (Mohan Kumar, 1967). The discussion centers on the cameo appearance of a British philosopher, Bertrand Russell, in the film along with phantasmal invocations of Indian anti-nuclear weapons protagonists such as India’s first prime minister, Jawaharlal Nehru, and reproductions of the 1945 atomic attack in Hiroshima and subsequent nuclear tests in the Pacific. The chapter considers how the film may be viewed in terms of a ‘corporeal compound lens’ on the political vicissitudes of the 1960s. With such an approach – on the one hand to do with the assemblage of a historical film, and on the other, to do with the way this intersects with compound lines of reflexive reception – the author shows how the ‘docu-drama-ment’ moves away from linear equations of the filmic signifier with the signified - or the film and the represented - to one that revels in affective residues and resonances that are a constitutive force in socio-political realities of the Cold War era.
Scorpion’s Tale
Authors: Hernández Kelly Lytle
Published: September 2020

This chapter offers a transnational and borderlands framework to reveal how the U.S. and Mexican governments conspired together to use the jail system to quell Mexico’s political revolution. The chapter chronicles the story of Ricardo Magonista’s incarceration in the U.S. from 1907 to 1910 and the ways in which the Mexican and U.S. governments had a shared interest in Magonista’s prolonged incarceration. The chapter takes up a transnational approach to incarceration that demonstrates the ways in which opposing states hoped to silence political radicals through criminalization across national borders. Yet even as states collaborated across borders to use jails and prisons as a place to silence dissent, this chapter reveals how incarceration had the ironic effect of creating new opportunities to orchestrate political and military assaults against the Porfirio Díaz regime. The chapter concludes that the U.S. jailing of Magonistas failed to silence them as they fanned the flames of revolution from jail cells.
