Published: August 2020

We report a theoretical investigation and elucidation of the x-ray absorption spectra of neutral benzene and of the benzene cation. The generation of the cation by multiphoton ultraviolet (UV) ionization as well as the experimental measurement ofthe carbon K-edge spectra of both species using a table-top high-harmonic generation (HHG) source have been described in a companion paper [M. Epshtein et al., J. Am.Chem. Soc., submitted. Available on ChemRxiv]. We show that the 1sC -> pi transition serves as a sensitive signature of the transient cation formation, as it occurs outside of the spectral window of the parent neutral species. Moreover, the presenceof the unpaired (spectator) electron in the pi-subshell of the cation and the high symmetry of the system result in significant differences relative to neutral benzene in the spectral features associated with the 1sC ->pi* transitions. High-level calculations using equation-of-motion coupled-cluster theory provide the interpretation of the experimental spectra and insight into the electronic structure of benzene and its cation.The prominent split structure of the 1sC -> pi* band of the cation is attributed to the interplay between the coupling of the core -> pi* excitation with the unpaired electronin the pi-subshell and the Jahn-Teller distortion. The calculations attribute most ofthe splitting (~1-1.2 eV) to the spin coupling, which is visible already at the Franck-Condon structure, and estimate the additional splitting due to structural relaxation tobe around ~0.1-0.2 eV. These results suggest that x-ray absorption with increased resolution might be able to disentangle electronic and structural aspects of the Jahn-Tellereffect in benzene cation.

Published: August 2020

Las enfermedades cardiovasculares están relacionadas con procesos inflamatorios prolongados o persistentes que causan el aumento de los niveles de reactantes de fase aguda como la proteína C reactiva (PCR), el fibrinógeno y las interleucinas IL-1 e IL-6. Desde este punto es importante saber si existen en los ecuatorianos polimorfismos genéticos ya establecidos para otras poblaciones, en especial en las citosinas IL-1 e IL-6. El objetivo del estudio fue relacionar la proteína C reactiva ultrasensible (PCR-us) en pacientes con cardiopatía isquémica. Se analizaron un total de 91 personas: 50 pacientes con criterios de inclusión para el diagnóstico de cardiopatía isquémica y 41 pacientes sin criterios de inclusión o síntomas de cardiopatía isquémica, escogidos en el área de consulta externa y hospitalización de los Servicios de Cardiología del hospital de Especialidades de las FF.AA. N° 1- Quito y del hospital Carlos Andrade Marín (hospital IESS - Quito).
Entre los hábitos, en el grupo de casos prevaleció el tabaquismo 11 pacientes (22 %) seguidos por el alcoholismo y tabaquismo juntos 9 (18 %). 25 individuos (50 %) de este grupo manifestó no tener hábito alguno, debemos mencionar que muchos de estos pacientes acudían a consulta externa de cardiología donde recibían educación médica.
El nivel de glicemia en ayunas mayor a 100 mg/dl encontró asociación de padecer cardiopatía isquémica (OR = 4.13, IC 95 %: 1.54 – 11.0), (p = 0.03).
Los niveles de LDL, colesterol, triglicéridos y de glicemia en el grupo de los casos fueron superiores en relación con el grupo control.
La lectura inmediata de la PCR-us no tuvo una diferencia significativa: p = 0.20 IC del 95 % entre los dos grupos de estudio. Igualmente la lectura de la PCR-us a los 30 minutos: p = 0.21 IC del 95 %.
Existe gran interés clínico y fisiopatológico en el desarrollo de nuevos marcadores que nos permitan un diagnóstico rápido y preciso en personas con mayor riesgo de desarrollar futuros eventos cardiovasculares.

Authors: Ordoñez Marí­a Eugenia 
Published: August 2020

Se determinó el haplotipo mitocondrial de 131 aislamientos puros de Phytophthora andina colectados de tomate de árbol (Solanum betaceum) en varias provincias del Ecuador. Se amplificaron las regiones P2 y P4 del ADNmt, y los productos de PCR obtenidos fueron digeridos con las enzimas de restricción MspI y EcoRI. Todos los aislamientos analizados mostraron un patrón de bandas correspondiente al haplotipo Ia para P. infestans, es decir, bandas de tamaño 720 y 350 pb con MspI (región P2) y bandas de tamaño 394, 361 y 309 pb con EcoRI (región P4). Sin embargo, también se observó de forma consistente en todos los aislamientos analizados bandas adicionales que no han sido reportadas anteriormente. Para la región P2 se obtuvieron bandas adicionales de 400 y 500 pb y un fragmento no digerido de 1070 pb, y para la región P4 bandas adicionales de 603 y 755 pb además de un fragmento no digerido de 964 pb. El encontrar un patrón nuevo de bandas de manera consistente para todos los aislamientos de P. andina analizados sugiere que la descripción del haplotipo Ia asignado a P. andina de tomate de árbol deberí­a ser redefinido.
Indian Languages in Election Manifesto of Seventeenth Lok Sabha Election-2019 in the interest of strengthening democracy
Authors: Sharma Anuradha 
Published: August 2020

Democracy is a system that respects the feelings of the people. But some experience in the context of India is the opposite. Here in the name of democracy, the system, which removes the system from the language of 'Lok', has continued to dominate. In this vision, words are called out, calling it true and good democracy. Distance from the local language of administration is the root of many problems, so the insistence on keeping distance from the language of justice puts a question mark on justice. The side effect of this is that education is also embracing the language which negates the self-respect of the folk language. The most negative aspect of Indian democracy is to alienate Indian languages ​​from their natural rights.
लोकतंत्र लोक की भावनाओं का आदर करने वाली व्यवस्था है। लेकिन भारत के संदर्भ में कुछ अनुभव इसके विपरीत है। यहां लोकतंत्र के नाम पर व्यवस्था को ‘लोक’ की भाषा से दूर करने वाले ‘तंत्र’ लगातार हावी रहे हैं। इस दृष्टि में उसे सच्चा और अच्छा लोकतंत्र कहते हुए शब्द ठिठकते है। प्रशासन की लोक भाषा से दूरी अनेक समस्याओं का मूल है तो न्याय की लोक की भाषा से दूरी बनाये रखने की जिद्द न्याय पर प्रश्नचिन्ह लगाती है। इसी का दुष्प्रभाव है कि शिक्षा भी उस भाषा से आलिंगन कर रही है जो लोक भाषा के स्वाभिमान को नकारती है। भारतीय भाषाओं को उनके स्वाभाविक अधिकारों से विमुख करना भारतीय लोकतंत्र का सर्वाधिक नकारात्मक पक्ष है।

The Effect of Using Flipped Classroom Model to Improve Iraqi EFL Learners’ Pronunciation in English at University Level
Authors: Waleed Husam Al-Mofti Khaldoon 
Published: August 2020

For Iraqi EFL learners who are studying English pronunciation in a traditional instruction method often requires more effort and hard work. Thus, using new methods of teaching such as the flipped classroom model (FCM) is necessary to facilitate learning and improve performance. Hence, this study reports on explanatory research that investigates the effect of using the FCM in the teaching of English pronunciation for Iraqi EFL learners at the university level. The study implemented mixed research methods for data collection in a quasi-experimental analysis. Therefore, two tests were conducted on the assigned groups to measure the effect of the FCM before and after the intervention. Besides, a questionnaire and interviews were used on the experiment group students to collect data about their perceptions of the FCM. The study length (lasted) was 15 weeks and is comprised of 60 students from the department of English, College of Arts at the University of Anbar. The students were divided into two groups, experimental, and control with 30 students in each group. The findings revealed that there was a significant statistical difference between the two groups in favour of the experimental group with better performance, indicating that the FCM has considerably assisted the Iraqi EFL learners to improve their English pronunciation. Moreover, the students expressed their positive feedback and satisfaction on the use of the FCM in their responses to the questionnaire and the interviews. As such, the current study recommends further research to study the effect of applying the FCM in areas and disciplines other than language learning.

Production and properties of functionally graded hybrid composites containing Al3Ti and TiB2
Authors: Savaş Ömer 
Published: August 2020

AbstractThis study examined the production and properties of functionally graded hybrid composites containing titanium di-boride (TiB2) and titanium tri-aluminate (Al3Ti) particles. The composites were produced by the centrifugal solid particle method at 850 °C. A detailed study of the microstructures, hardness and abrasive wear behavior of the hybrid composites was carried out. The results showed that the produced composites had three different regions along the centrifugal force direction. It was found that there were Al3Ti particles in the outer region, TiB2 particles in the middle region and neither Al3Ti nor TiB2 particles in the inner region of the functionally graded composites. It was determined that the abrasive wear properties of the composites were improved by 5 times with about 33 wt.% Al3Ti and by 3 times with about 7 wt.% TiB2 in comparison to the pure aluminum matrix.

Published: August 2020

AbstractDue to the increasing complexity of materials processed in primary and secondary lead smelting, better control of impurity elements is required. In the present study, distributions of Cu, As, Sb and Sn between PbO–FeO–Fe2O3–SiO2 slag and Pb metal are characterized experimentally and analyzed using thermodynamic calculations. Experimental methodology involved closed-system equilibration of sample mixtures at high temperature followed by rapid quenching. The compositions of phases were measured using electron probe X-ray microanalysis and laser ablation inductively coupled plasma mass spectrometry. Thermodynamic calculations were performed using the FactSage software coupled with an internal thermodynamic database. Experimentally obtained distribution coefficients wt.% in slag/wt.% in metal at 1 200 °C (1 473 K) follow the sequence Sn >> Cu > As ≈ Sb at P(O2) < 10−9.5 atm and Sn >> As ≈ Sb > Cu at P(O2) > 10−8.5 atm. Model predictions are in good agreement with the experiment.
Energy Sources for Fusion Additive Manufacturing Processes
Authors: Nassar Abdalla R. , Reutzel Edward W. 
Published: August 2020

AbstractFusion-based additive manufacturing (AM) processes rely on the formation of a metallurgical bond between a substrate and a feedstock material. Energy sources employed in the fusion AM process include conventional arcs, lasers, and electron beams. Each of these sources is discussed, with an emphasis on their principles of operation, key processing variables, and the influence of each source on the transfer of heat and material. Common energy sources used for metals AM processes, particularly powder-bed fusion and directed-energy deposition, are also discussed. Brief sections at the end of the article discuss the factors dictating the choice of each of these energy sources and provide information on alternative sources of AM.
Defects in Metal Additive Manufacturing Processes

Published: August 2020

Abstract
The formation of defects within additive-manufactured (AM) components is a major concern for critical structural and cyclic load applications. Thus, understanding the mechanisms of defect formation in fusion-based processes is important for prescribing the appropriate process parameters specific to the alloy system and selected processing technique. This article discusses the formation of defects within metal additive manufacturing, namely fusion-based processes and solid-state/sintering processes. Defects observed in fusion-based processes include lack of fusion, keyhole collapse, gas porosity, solidification cracking, solid-state cracking, and surface-connected porosity. The types of defects in solid-state/sintering processes are sintering porosity and improper binder burnout. The article also discusses defect-mitigation strategies, such as postprocess machining, surface treatment, and postprocessing HIP to eliminate defects detrimental to properties from the as-built condition. The use of noncontact thermal, optical, and ultrasound techniques for inspecting AM components are also considered. The final section summarizes the knowledge gap in our understanding of the defects observed within AM components.
