Ammonium dinitramide (ADN), as a novel oxidizer characterized by high energy density, low signature, and environmental friendliness, exhibits significant application potential in composite solid propellants. However, its...

The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor´s hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plateaus (∼100 days) and the most massive...

Ukrainian university students facing profound mental health challenges during the ongoing war, a humanitarian crisis exacerbated by cognitive warfare - efforts to destabilise consciousness, erode trust and manipulate emo...

Poverty has been defined by several authors and international organizations from similar perspectives. However, those definitions tend to be simplistic and not powerful enough to deal with complex situations that involve...

With the development of Micro-Electro-Mechanical Systems (MEMS) technology, the manufacture of energy conversion elements with metal bridge membranes is becoming more mature, which can be applied in the field of self-des...

We present optical and near infrared observations of the type IIb supernova (SN) 2011fu from a few days to ∼300 d after explosion. The SN presents a double-peaked light curve (LC) similar to that of SN 1993J, although ...

Core-collapse supernova remnants (CCSNRs) are crucial for understanding the final stages of massive star evolution, as they reflect the imprints of their progenitors’ preexplosion activities. However, the evolution of ...

Using single-shot velocity map imaging technique, explosion imaging of different ion species ejected from 50 nm SiO2 nanoparticles are obtained excitedly by strong near-infrared and ultraviolet femtosecond laser fields....

Fast modulation of optical signals that carry multidimensional information in the form of wavelength, phase or polarization has fueled an explosion of interest in integrated photonics. This interest however masks a signi...

Abstract The stable fly (Stomoxys calcitrans) has historically been a pest of dairy cattle and feedlots due to the availability of decaying plant matter mixed with animal excrements in such production systems. In the las...

Abstract Background The ongoing conflict in Sudan has disrupted many aspects of life, and university students are among those most affected. Medical students at the University of Khartoum, in particular, are under intens...

Supernova LSQ13abf was discovered soon after explosion by the La Silla-QUEST Survey and then followed by the Carnegie Supernova Project II at its optical and near-IR wavelengths. Our analysis indicates that LSQ13abf was ...

Ultra-massive white dwarfs are powerful tools used to study various physical processes in the asymptotic giant branch (AGB), type Ia supernova explosions, and the theory of crystallization through white dwarf asteroseism...

The ongoing war in Ukraine has led to an increased incidence of sensorineural hearing loss (SNHL) resulting from acoustic trauma caused by firearms or explosions among both military personnel and civilians. This type of ...

El presente artículo analiza las particularidades del proceso de trasferencia genérica de la novela gótica inglesa a la literatura española en el período de entresiglos (1788-1833), que quedan fijadas en una fase de...

Poco puede sorprender al lector encontrarse en la actualidad con un título que invoque la memoria colectiva. De un tiempo a esta parte, hemos asistido a una suerte de explosión o auge –como objeto de investigación d...

El estudio de los fenómenos de interacción entre agregados estelares y el medio circundante constituye un interesante campo de investigación astrofísica, con una clara vigencia en el aspecto observacional. Esta Tesis...

En los últimos 20 años nuestro conocimiento acerca de las condiciones físicas que prevalecen en el Medio Interestelar local se ha ido incrementando paulatinamente, gracias a medidas de la radioemisión continua realiz...

El Universo, colmado de todo tipo de objetos interesantes y diversidad de fenómenos, representa el “zoológico” más fascinante y maravilloso que uno jamás pueda imaginar. La Astrofísica, engloba la búsqueda cien...

En este trabajo se analizan los perfiles de la línea de 21 cm del hidrógeno neutro pertenecientes a la región galáctica 110° ≤ Z ≤ 130°, 0° ≤ b ≤ 25°, en la zona de Cefeo, con el fin de determinar la dist...

With the increasing relevance of energy transition, synthetic fuels have arisen as an alternative to storage green energy. In the processing of this fuels, carbon monoxide is widely used. Understanding the behaviour of t...

La creciente explosión de la información a nivel mundial y en consecuencia el aumento del conocimiento , la búsqueda imperiosa de soluciones a los crecientes problemas globales cada vez más complejos y la urgencia po...

En esta Tesis se analizan las consecuencias que tiene la transisión de materia hadrónica a materia de quarks cuando ocurre durante las últimas etapas de la evolución de estrellas masivas y durante el proceso de forma...

Fil: Lazzaro, Pablo Catriel. Universidad de Buenos Aires. Facultad de Agronomía. Argentina. En las plantas de silos o de acopio, se realiza el proceso de recepción de los granos después de la cosecha. Estos son acondi...
