Towards an African Christian Theology of the Blood of Jesus Christ
Authors: Yashim Stephen Z. , Umar Emmanuel
Published: July 2020

This article proposes an African Christian theology of the blood of Jesus Christ which biblically explains and answers experiential questions raised in African historical and socio-cultural contexts. Through the process of conceptual analysis, articles on animal sacrifices in African Traditional Religions and articles in the theological fields of Biblical Theology and Systematic Theology are interrogated to propose an African Christian Theology of the blood of Jesus Christ. The proposed African Christian Theology of the blood of Jesus Christ posits that God acts on the basis of the vicarious shedding of the blood of Jesus Christ to incorporate believers into a Father-Child relationship that grants the believer access to a special divine benevolence. God’s benevolence is the means by which the believer experiences the transformative power of God that leads them to progressively experience improvements for their holistic well-being while anticipating the return of Jesus Christ to reinstate perfect holistic well-being for God’s people.

Keywords: The blood of Jesus, Animal sacrifices, and African Christian Theology.
Who Said, No Mission In The Old Testament: A Theological Framework Of Mission In The Isaianic Literature
Authors: Marfo Elisha Kwabena
Published: July 2020

This paper delineates the theological framework of the Isaianic theology of mission and how mission contributes to the overall theology of Isaianic literature. In the theological synthesis, the investigation established that there is a connection between YHWH, His attributes, mission, Israel, and the nations. The article revealed how YHWH relates to His mission and creation as well as to His redemptive purpose for all humanity. The abundant evidence in Isaianic literature concerning the theology of mission is related to the realization that YHWH’s redemptive or salvific plans and work are inescapable when His mission to all humanity is a concern. When these are misjudged, a disconnect between YHWH’s attributes and His redemptive purpose for the peoples of the whole universe occurs. YHWH has established an inseparable union between His mission and salvation to all humanity. Through the mission theology, Isaiah’s language of redemption is sharpened, and the tenor of his salvific purpose espoused. Keywords: YHWH, Mission, Isaianic literature, theology, Isreal, Nations

El error de diagnóstico de la derecha chilena y la encrucijada actual
Authors: Rovira Kaltwasser Cristóbal
Published: July 2020

El estallido social de fines del año 2019 ha abierto una serie de conflictos al interior de la derecha chilena. Ahora bien, estos conflictos no surgieron de la noche a la mañana, sino que tienen sus orígenes en la existencia de distintas interpretaciones respecto de cómo es la sociedad chilena de hoy en día y de cuáles son las mejores estrategias para desarrollar un perfil electoral competitivo. Para comprender esta problemática, en este artículo se ofrece una discusión teórica sobre la tensión entre moderación y radicalización que experimenta la derecha, para luego proceder a revisar evidencia empírica del caso chileno sobre las transformaciones de las preferencias de la sociedad y las estrategias electorales que ha venido desarrollando la derecha. Interesa argumentar que el segundo gobierno de Sebastián Piñera, que ganó la elección presidencial el año 2017, se basó en un profundo error de diagnóstico sobre el país. Esto no solo facilitó la irrupción del estallido social, sino que también ha pavimentado el camino para que se agraven las tensiones al interior de la derecha. De ser cierta la tesis que acá se plantea, lo más probable es que en un futuro cercano deje de existir una sola coalición de derecha, posibilitándose así la conformación de pactos gubernamentales inéditos hasta ahora.

The paper deals with the environmental costs (EC) in the electrical equipment industry by using environmental accounting as a strategic instrument for
controlling the economic entity (EE). The novelty of the study consists of integrating a mathematical model in environmental management accounting (EMA), starting from the
identification of the types of waste generated by the production flow and the interaction between the production activity and the environment, which results in determining
the EC per entity. The research also analyzes the dependence between the resulting waste and the volume of production by categories. The usefulness of determining these
dependencies leads to the identification of the product categories with a significant influence on the EC. The study is useful for developing an environmentally sustainable
accounting system within entities in the electrical equipment industry because based on the mathematical model, products that generate large quantities of waste can be
identified, allowing the outline of managerial strategies to reviewing production technologies, in order to optimize the products and reduce the quantities of waste
generated.
Advancing the Velocity Gradient Technique: Using Gradient Amplitudes and Handling Thermal Broadening
Authors: Yuen Ka Ho , Lazarian Alex
Published: July 2020

The recent development of the velocity gradient technique allows observers to map magnetic field orientations and magnetization using the direction of velocity gradients. Aside from the directions, amplitudes of velocity gradients also contain valuable information about the underlying properties of magnetohydrodynamic (MHD) turbulence. In this paper, we explore what physical information is contained in the amplitudes of velocity gradients and discuss how this information can be used to diagnose properties of turbulence in both diffuse and self-gravitating interstellar media. We identify the relations between amplitudes of both intensity and velocity centroid gradients and the sonic Mach number M

s
, and they are consistent with the theory’s predictions. We test the robustness of the method and discuss how to utilize the amplitudes of gradients into self-gravitating media. To extend the velocity gradient technique, we also discuss the usage of amplitude method to position–position–velocity space as a possible way to retrieve the velocity channel maps before the contamination of thermal broadening. We discuss that the velocity gradient technique with these advancements could potentially give a significantly more accurate statistical insight into the properties of magnetized turbulence.
On the Relationship between Magnetic Expansion Factor and Observed Speed of the Solar Wind from Coronal Pseudostreamers
Authors: Wallace Samantha , Arge C. Nick , Viall Nicholeen , Pihlström Ylva
Published: July 2020

For the past 30+ yr, the magnetic expansion factor (f

s
) has been used in empirical relationships to predict solar wind speed (v
obs) at 1 au based on an inverse relationship between these two quantities. Coronal unipolar streamers (i.e., pseudostreamers) undergo limited field line expansion, resulting in f

s
-dependent relationships to predict the fast wind associated with these structures. However, case studies have shown that the in situ observed pseudostreamer solar wind was much slower than that derived with f

s
. To investigate this further, we conduct a statistical analysis to determine if f

s
and v
obs are inversely correlated for a large sample of periods when pseudostreamer wind was observed at multiple 1 au spacecraft (i.e., ACE, STEREO-A/B). We use the Wang–Sheeley–Arge model driven by Air Force Data Assimilative Photospheric Flux Transport (ADAPT) photospheric field maps to identify 38 periods when spacecraft observe pseudostreamer wind. We compare the expansion factor of the last open field lines on either side of a pseudostreamer cusp with the corresponding in situ measured solar wind speed. We find that only slow wind (v
obs < 500 km s−1) is associated with pseudostreamers and that there is not a significant correlation between f

s
and v
obs for these field lines. This suggests that field lines near the open–closed boundary of pseudostreamers are not subject to the steady-state acceleration along continuously open flux tubes assumed in the f

s
–v
obs relationship. In general, dynamics at the boundary between open and closed field lines such as interchange reconnection will invalidate the steady-state assumptions of this relationship.

Published: July 2020

We present a dust spectral energy distribution (SED) and binary stellar population analysis revisiting the dust production rates (DPRs) in the winds of carbon-rich Wolf–Rayet (WC) binaries and their impact on galactic dust budgets. DustEM SED models of 19 Galactic WC “dustars” reveal DPRs of

M
⊙ yr−1 and carbon dust condensation fractions, χ

C
, between 0.002% and 40%. A large (0.1–1.0 μm) dust grain size composition is favored for efficient dustars where χ

C
 ≳ 1%. Results for dustars with known orbital periods verify a power-law relation between χ

C
, orbital period, WC mass-loss rate, and wind velocity consistent with predictions from theoretical models of dust formation in colliding-wind binaries. We incorporated dust production into Binary Population and Spectral Synthesis (BPASS) models to analyze dust production rates from WC dustars, asymptotic giant branch stars (AGBs), red supergiants (RSGs), and core-collapse supernovae (SNe). BPASS models assuming constant star formation (SF) and a coeval 106
M
⊙ stellar population were performed at low, Large Magellanic Cloud (LMC)–like, and solar metallicities (Z = 0.001, 0.008, and 0.020). Both constant SF and coeval models indicate that SNe are net dust destroyers at all metallicities. Constant SF models at LMC-like metallicities show that AGB stars slightly outproduce WC binaries and RSGs by factors of 2–3, whereas at solar metallicities WC binaries are the dominant source of dust for ∼60 Myr until the onset of AGBs, which match the dust input of WC binaries. Coeval population models show that, for “bursty” SF, AGB stars dominate dust production at late times (t ≳  70 Myr).

The formation and evolution of binary stars are critical components of several fields in astronomy. The most numerous sources for gravitational wave observatories are inspiraling or merging compact binaries, while binary stars are present in nearly every electromagnetic survey regardless of the target population. Simulations of large binary populations serve to both predict and inform observations of electromagnetic and gravitational wave sources. Binary population synthesis is a tool that balances physical modeling with simulation speed to produce large binary populations on timescales of days. We present a community-developed binary population synthesis suite, COSMIC, which is designed to simulate compact-object binary populations and their progenitors. As a proof of concept, we simulate the Galactic population of compact binaries and their gravitational wave signals observable by the Laser Interferometer Space Antenna.

Authors: Martos-Martins Rafael , Donatelli Reginaldo J.
Published: July 2020

As urban areas expand, some species of diurnal birds of prey occupy these habitats, and many establish viable populations. The objectives of this study were to: (1) survey the species of birds of prey in the urban area located in the interior of the São Paulo state, Brazil, (2) to verify the proportion of generalist and specialist species in terms of habitat and diet, (3) determine the period that the species are more active during the time period of the point counts, and (4) to evaluate if there is a pattern of seasonality. Samples were collected monthly between October 2014 and September 2016 using the point counts method (four points; 4 hr duration each). We analyzed species richness, habitat and diet, number of contacts and frequency of occurrence, period of greatest activity, and seasonality. We recorded 19 species of birds of prey through 2555 contacts. Most of the registered species (61%) were habitat and diet generalists, and the same percentage of species classified as uncommon or rare. In relation to the period of greatest activity, falconids were more active in the first hour while accipitrids and cathartids were more active in the fourth hour. In addition, we did not observe a seasonal pattern in this community, butGampsonyx swainsoniishowed a seasonal trend. We verified that the urban area of the municipality of Pirajuí has a significant diversity of birds of prey, including specialist species of habitat and diet. This information obtained evidence the importance of urban environments for birds of prey and showed the ability of these species to use this environment. From our results, we suggest that future studies should evaluate the effects of urban areas of different sizes and degrees of urbanization on bird of prey communities.

Bacillary Layer Detachment in Bilateral Diffuse Uveal Melanocytic Proliferation Masquerading as Neovascular AMD
Authors: Breazzano Mark P. , Bacci Tommaso , Wang Hao , Francis Jasmine H. , Yannuzzi Lawrence A.
Published: July 2020

Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare and unusual paraneoplastic ocular syndrome with generally poor prognosis. The authors present a case of BDUMP in a patient with bladder cancer, examined with current multimodal imaging. In the clinical setting with drusen and exudative macular detachments, the fundus simulated neovascular age-related macular degeneration, warranting standard-of-care therapy. The imaging actually showed the typical manifestations of BDUMP, but also newly recognized, associated manifestations, including the bacillary layer detachment, a gravitating retinal detachment, and multifocal choroidal hyperpermeability, but no evidence of neovascularization. Recognition of these associated manifestations is of value in appreciating the pathophysiology of this paraneoplastic disorder. Based on the imaging, the correct diagnosis was possible along with a better understanding of the nature of the clinical features in the posterior fundus.

Main Defects Observed in Titanium GRADE II and 316L Stainless Steel Elements Obtained by Selective Laser Melting
Authors: Woźniak Anna , Adamiak Marcin
Published: July 2020

Selective Laser Melting SLM is one of the most popular three dimensional printing methods, which can be used for manufactured real elements (with high geometrical complexity) in many application, such as medicine, automotive or aerospace industries. The SLM final parts are characterized by high mechanical properties and satisfactory physicochemical properties. However, the properties of parts depend of process parameters optimization. In this paper, effects of processing parameters, such as laser power P, scanning speed SP, layer thickness t or point distance PD on defect formation and relative densities of manufactured elements are explored. For the purpose the stainless steel 316L and pure titanium Grade II are used. The process optimization were carried out according to the formula of energy density, which is delivered to the powder material. The stainless steel samples were divided into 12 groups, depends of the energy density. The titanium parts were printed at the same value of energy, and the process parameters are changed. The microscope observation and relative density measurements were carried out. Based on the obtained results, it can be confuted that the SLM parameters have a significant effect on the samples properties and the mechanism formed defect in both material are similar.

The laser surface alloying was executed by direct introduction of metallic powder Fe/Cu into the remelted area (molten pool). As a heat flux, the Hight Power Fiber Laser (HPFL) has been used. Metallic powder before the treatment was mixed in a ball mill and dried on the hot plate (90°C temperature). The mechanical and tribological properties of alloyed surface were analysed including hardness (HRF), microhardness (HV0.1) and ball-on-plate wear test. The structure of the laser alloyed surface was evaluated by light and scanning electron microscopy.
Fabrication of TiC-Reinforced Surface Layers on Ductile Cast Iron Substrate by Laser Surface Alloying
Authors: Janicki Damian
Published: July 2020

This chapter presents a novel method for analysis and optimization of the in-situ formation of TiC-reinforced composite surface layers (TRL) on a ductile cast iron substrate during the laser surface alloying process, combining the experimental approach with the computational thermodynamics. The microstructure of the TRLs has been assessed by light optical microscopy, scanning electron microscopy with energy dispersive spectroscopy and X-ray diffraction. The results of thermodynamic calculations with the Scheil-Gulliver model showed a good agreement with the experimental results, indicating that the actual solidification path for the analyzed Fe-C-Si-Ti alloy systems under the investigated range of laser processing conditions is close to the Scheil-Gulliver assumption.

Previous research showed that visual utilisation in mathematics classrooms help students in understanding concepts. This study was conducted to assist educators in realising visual reasoning skills in students which can be employed in classroom practices as the students move to their higher levels of education. The study is part of a larger project. It studied 194 pre-university students’ perception of the use of graphs and examined their actual ability to extract information embedded in the graphs in order to understand and solve derivative problems. Findings showed that students were very encouraged to use graphs in the teaching and learning of mathematics but the opposite was evident in their worked solutions. Implications of teaching and learning are also discussed.

In each school, two classes were chosen with one class was given a discovery learning treatment with visualization of proofs (PWW) and the other class was given a discovery learning treatment without visualization of proofs. The measurement instrument used in this study was an essay test instrument with five questions. Discovery learning is said to be effective if the average value of conceptual understanding is at least 75. Based on the results of this study, although the data obtained did not meet the assumptions of normality, the number of members of the sample were more than 30 so that the data analysis could use parametric statistics. Using a hypothesis testing with a significance level of 0.05, it was found that the use of visualization of proofs was effective in mathematics discovery learning models if it was viewed from conceptual understanding.

Published: July 2020

In this paper, we study the evolution of hourly oil price volatility. Using multiple measures of oil price volatility, we conclude that volatility increased following the onset of COVID-19. After controlling for conventional predictors of oil price volatility, we show that COVID-19 cases and deaths led to an increase in daily oil price volatility by between 8% and 22%. Our results pass a battery of robustness tests.

Authors: Véliz José
Published: July 2020

En los últimos 20 años los estudios relacionados a la acreditación de las universidades y escuelas de negocios han sido escasos. Por otro lado, las investigaciones realizadas han sido liderados por países como: Estados Unidos, Canadá, India y Reino Unido. De tal forma que, en los países latinoamericanos no se hace énfasis en el impacto que tiene la acreditación de las universidades y escuelas de negocios sobre la sociedad; a pesar de que varios de estos países cuentan con instituciones de educación superior acreditadas.  Dado aquello, el presente estudio tiene como objetivo argumentar sobre la importancia de la acreditación de las escuelas de negocio, considerando las dimensiones que aborda y su implicancia en la innovación, además de describir cuáles son sus factores claves de éxito, su principal impacto en la calidad educativa empresarial y los costos asociados. Se concluye que, en efecto, uno de los aportes de la acreditación en la educación empresarial es brindar profesionales altamente cualificados que promuevan el aprovechamiento de oportunidades de negocios en los diferentes mercados locales e internacionales.

The present study was conducted during quarantine which was caused due to the pandemic of COVID-19 virus in Greece. We try to detect the immediate psychological effects of crisis conditions on university students, focusing on the symptoms of depression. The main goal is to evaluate the clinical depression that students present due to quarantine. The study participants were 570 students of the University of Patras, who completed an electronic questionnaire that includes demographic data and the BECK (BDI) depression scale, which measures the severity of depression. The results show that a significant percentage of participating students at the University of Patras reported increased symptoms of depression. Students' mental health seems to be significantly affected when situations of social constraint arise and, consequently, require attention and help. Critical, therefore, the role of the University is emerging in providing students adequate psychological services in order to strengthen and support them.

Published: July 2020

Mondros Mütarekesi ile Birinci Dünya Savaşı’ndan çekilen Osmanlı Devleti, savaş sırasında bulunduğu bütün cephelerde silah bırakmayı, savaştan önceki sınırlarına çekilmeyi ve ordularını terhis etmeyi kabul etmişti. Bunu fırsat bilen İtilaf kuvvetleri de kısa sürede Osmanlı topraklarını işgale başlamışlardı. Bu işgaller, Osmanlı Devleti sınırları içinde yaşayan Rum ve Ermenileri heyecana getirmiş ve toprak taleplerinin karşılanması için başta Yunanistan olmak üzere İtilaf kuvvetlerine her türlü yardımı yapmışlardı. Ayrıca kendi aralarında yaptıkları ittifaklarla da işgal sürecine büyük destek vermişler ve Millî Mücadele’yi engellemeye çalışmışlardı. Fakat bu durum Anadolu’da Millî Mücadele’yi akamete uğratmaktan ziyade aksine güçlenmesini sağlamıştı.
