|January 2, 1987
Resumen
La estrella invitada de A.D. 185, posiblemente la supernova más antigua registrada, puede no estar vinculada a la fuente de radio RCW 86. Un nuevo análisis sugiere una visibilidad más corta y una ubicación diferente para este antiguo evento astronómico.
Área de la Ciencia:
- La astronomía es la astronomía.
- La astrofísica es la astrofísica.
- La Astronomía Histórica fue la Astronomía Histórica.
Sus antecedentes:
- La estrella invitada de A.D. 185 es históricamente considerada la supernova más antigua registrada.
- Se ha creído ampliamente que la fuente de radio RCW 86 es el remanente de esta supernova de 185 d.C.
- Estudios anteriores propusieron una duración de 20 meses y una ubicación entre alfa y beta Centauri para el evento de 185 d.C.
Objetivo del estudio:
- Reevaluar la asociación entre el A.D. 185 estrella invitada y la fuente de radio RCW 86.
- Para determinar la duración exacta de la visibilidad y la ubicación celeste de la estrella invitada A.D. 185.
- Evaluar críticamente los registros históricos astronómicos para la identificación de supernovas.
Principales métodos:
- Estudio de la antigua literatura astronómica china en relación con el A.D. 185 estrella invitada.
- Análisis comparativo de descripciones históricas con las características de RCW 86.
- Reevaluación de la duración y ubicación propuestas sobre la base de pruebas textuales.
Principales resultados:
- La literatura china antigua sugiere que RCW 86 no está relacionado con la estrella invitada A.D. 185.
- La estrella invitada de 185 d.C. probablemente tuvo una duración visible de sólo 7 meses.
- La ubicación probable del evento fue entre beta y delta Centauri, no entre alfa y beta Centauri.
Conclusiones:
- El vínculo ampliamente aceptado entre la supernova A.D. 185 y RCW 86 es probablemente incorrecto.
- Comprensión revisada de las características del evento de 185 d.C. basado en el análisis de textos históricos.
- Este estudio requiere un nuevo examen de otros posibles restos de supernovas y registros históricos.

01:46The Calvin Benson Cycle
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...
01:34Crossing Over
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process called synapsis.

01:30Crossing Over
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I, duplicated...

01:31Adrenergic Receptors: ɑ Subtype
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...

01:10Review and Preview
In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
