Published: July 2020

El objetivo del trabajo fue analizar las diferencias de algunos parámetros hematológicos, bioquímicos y morfométricos entre bubillas y búfalas de dos establecimientos (Itatí y Empedrado) de la Provincia de Corrientes, Argentina. Se emplearon 60 hembras bubalinas, raza mediterránea, 15 por categoría. Se registró el peso vivo (PV) y el perímetro torácico (PT). Se tomaron muestras sanguíneas para valorar hematocrito (HTO), hemoglobina (HB), recuento de eritrocitos (RGR) y leucocitos (RGB), volumencorpuscular medio (VCM), hemoglobina corpuscular media (HCM) y concentración de HCM (CHCM). En el suero se estimaron urea, proteínas totales (PRT), albúminas (ALB), globulinas (GLOB), relación albúmina-globulina (RAG), colesterol (CT, C-HDL y C-.LDL), triglicéridos (TR), calcio (CA), fósforo (FOS), magnesio (MG), glucosa y actividad de lactato deshidrogenasa (LDH). Se utilizó un diseño experimental de arreglo factorial, donde la variable independiente fue la localidad y el tratamiento la categoría, valorándose la interacción de localidad x edad. Con el programa InfoStat se efectuó la estadística descriptiva y el ANOVA. La interacción significativa de algunas variables motivó el tratamiento por sus efectos simples. Las búfalas de Empedrado presentaron mayores PV, PT, neutrófilos, eosinófilos, CT, TR y urea, mientras que las bubillas tuvieron elevados linfocitos, CA, glucosa y LDH. Las búfalas de Itatí revelaron mayores PV, PT, HTO, RGR, CT y las hembras jóvenes elevados niveles de LDH. El efecto edad influyó, por lo cual las búfalas ostentaron mayores porcentajes de monocitos, PRT y GLOB, en tanto que en las bubillas fueron más altos RGB, FOS, C-HDL y C-LDL. Para el factor localidad los animales de Empedrado revelaron mayores niveles de HB, HCM, CHCM, RGR, monocitos y MG; los de Itatí mostraran elevadas PRT, ALB y RAG. No hubo diferencias para VCM y basófilos. La obtención de intervalos de referencia bioquímicos regionales asume importancia como herramienta para evaluar el estado nutricional y optimizar el diagnóstico de enfermedades.

Authors: Rasheed Luay Thamir 
Published: July 2020

The aim of this paper is to design a PID controller based on an on-line tuning bat optimization algorithm for the step-down DC/DC buck converter system which is used in the battery operation of the mobile applications. In this paper, the bat optimization algorithm has been utilized to obtain the optimal parameters of the PID controller as a simple and fast on-line tuning technique to get the best control action for the system. The simulation results using (Matlab Package) show the robustness and the effectiveness of the proposed control system in terms of obtaining a suitable voltage control action as a smooth and unsaturated state of the buck converter input voltage of ( ) volt that will stabilize the buck converter system performance. The simulation results show also that the proposed control system when compared with the other controllers results has the capability of minimizing the rising time to ( sec) and the settling time to ( sec) in the transient response and minimizing the voltage tracking error of the system output to ( ) volt at the steady state response. Furthermore, the number of fitness evaluations is decreased.
Utilizing Load and Loss Factors in Determination of the Technical Power Losses in Distribution System’s Feeders: Case Study
Authors: Amin Dara Hama 
Published: July 2020

This study uses load factor and loss factor to determine the power losses of the electrical feeders. An approach is presented to calculate the power losses in the distribution system. The feeder’s technical data and daily operation recorded data are used to calculate and analyze power losses.
This paper presents more realistic method for calculating the power losses based on load and loss factors instead of the traditional methods of calculating the power losses that uses the RMS value of the load current which not consider the load varying with respect to the time. Eight 11kV feeders are taken as a case study for our work to calculate load factor, loss factor and power losses. Four of them (F40, F42, F43 and F45) are overhead lines while the others (F185, F186, F187 and F188) are underground cables. The greater differences between their losses were obtained, due to various types of route length, type, and dimension of conductors. The study takes different configuration feeders for computation with determination in power losses.

OBJECTIVEIntracranial human brain recordings typically utilize recording systems that do not distinguish individual neuron action potentials. In such cases, individual neurons are not identified by location within functional circuits. In this paper, verified localization of singly recorded hippocampal neurons within the CA3 and CA1 cell fields is demonstrated.METHODSMacro-micro depth electrodes were implanted in 23 human patients undergoing invasive monitoring for identification of epileptic seizure foci. Individual neurons were isolated and identified via extracellular action potential waveforms recorded via macro-micro depth electrodes localized within the hippocampus. A morphometric survey was performed using 3T MRI scans of hippocampi from the 23 implanted patients, as well as 46 normal (i.e., nonepileptic) patients and 26 patients with a history of epilepsy but no history of depth electrode placement, which provided average dimensions of the hippocampus along typical implantation tracks. Localization within CA3 and CA1 cell fields was tentatively assigned on the basis of recording electrode site, stereotactic positioning of the depth electrode in comparison with the morphometric survey, and postsurgical MRI. Cells were selected as candidate CA3 and CA1 principal neurons on the basis of waveform and firing rate characteristics and confirmed within the CA3-to-CA1 neural projection pathways via measures of functional connectivity.RESULTSCross-correlation analysis confirmed that nearly 80% of putative CA3-to-CA1 cell pairs exhibited positive correlations compatible with feed-forward connection between the cells, while only 2.6% exhibited feedback (inverse) connectivity. Even though synchronous and long-latency correlations were excluded, feed-forward correlation between CA3-CA1 pairs was identified in 1071 (26%) of 4070 total pairs, which favorably compares to reports of 20%–25% feed-forward CA3-CA1 correlation noted in published animal studies.CONCLUSIONSThis study demonstrates the ability to record neurons in vivo from specified regions and subfields of the human brain. As brain-machine interface and neural prosthetic research continues to expand, it is necessary to be able to identify recording and stimulation sites within neural circuits of interest.

AbstractThis study aims to describe and analyze student errors in writing effective sentences. University students, especially those who were in the 1st semester, have not realized and developed Bahasa Indonesia as a skill. In the use of Bahasa Indonesian, students were not consciously guided by applicable language rules. Thus, the Bahasa Indonesian used by students was not as good and correct as expected by competence. Students have not been able to write effective sentences. There were still many students who have not applied the terms of effective sentences. In fact, the ability to write effective sentences is important for students.The approach in this research was qualitative. A qualitative approach was used in this study because the data analyzed were in the form of descriptions of observed phenomenon. In this case, the observed phenomenon was an error in writing effective sentences that occurred in the papers of hospitality students. The researcher identified the sentence that does not meet the requirements as an effective sentence and the factors behind the occurrence of the error.The results showed that students' skills in writing effective sentences were still poor. Of the five requirements for effective sentences, researchers found errors of four requirement. The accuracy was the only requirement in which no errors occurred. Based on the finding, researchers believe that students have been able to avoid writing ambiguous meaningful sentences. On the other hand, errors in clarity were very dominant found in student papers. Based on these facts, plus a test, the researcher concluded that the students have not been able to understand sentence structures well, even when students were asked to determine the subject and predicate in the sentence, more than 30% of students have not been able to determine precisely.

Authors: Bello Dikko 
Published: July 2020

An excellent reputation earned by initiating and practicing sustainable business practices has additional benefits, of which are reducing environmental incidents and an improvement in operational efficiency as this has the potential to help firms improve on productivity and bring down operating costs. Taken further, with ever-increasing socially and environmentally-conscious investors and the public alike, this act of natural resources management could have a significant implication on market value and income of the practicing firms.
The above proposition has been supported by sustainable business practices literature that is continuously conversing and deliberating upon the impact of efficient resource deployment and sustainable business practices. This paper aims to add value and contribute by offering inferences on cost reduction possibilities through improved natural resources management. Therefore it is an entirely conceptual level approach that provided potentially efficient tools for business sustainability and profitability
What’s in a Name

This paper argues that the coterminous trends of post-liberalism’s shifting global power relations and right wing populism (RWP) have been apparent in the persistent attacks on the World Health Organisation, controversies over the SARS-CoV-2 name, and other forms of disinformation during the current pandemic. Scientific expertise and technocratic knowledge have been diminished in a cacophony of political blaming and posturing, exposing once again the entangled nature of science and politics. It is critical for science education to consider this perspective given its central role in the production of future science and medical professionals able to navigate highly charged and contested political spaces.
