Prácticas de orden de magnitud. Saber decir y escribir los números

Prácticas de orden de magnitud. Saber decir y escribir los números El orden de magnitud de un número es la potencia decimal del valor relativo de su cifra significativa. Por tanto, se dice por ejemplo que dos números difieren 2 órdenes de magnitud si uno es 100 veces más grande que el otro. El uso más extendido de describir los órdenes de magnitud es mediante la notación científica o las potencias de diez. Por ejemplo, el orden de magnitud de 1500 es 3, ya que 1500 puede escribirse así:1,5 × 103. Descargue, desempaquete y ejecute la aplicación Convertens texten numeris con la cual podrá practicar la escritura de los números en español usando la escala larga y en inglés usando la escala corta, esta aplicación le enviará, vía correo electrónico, un reporte de los números practicados para permitir identificar las áreas a mejorar, también puede enviar un correo electrónico al docente y a quien practica. Ademas deja un registro en la página de salto al saber para poder comparar el progreso respecto a otras personas que usan la misma aplicación.

Researchers Identify Gene for Gray Hair: IRF4

Researchers Identify Gene for Gray Hair: IRF4 The team, led by Prof. Andres Ruiz-Linares of University College London, analyzed a population of 6,630 people with varied ancestry across Latin America to identify new genes associated with hair color, graying, density and shape, i.e. straight or curly. “Our study sample consists of 6,630 volunteers from the CANDELA cohort recruited in five Latin American countries (Brazil, Colombia, Chile, Mexico and Peru),” Prof. Ruiz-Linares and co-authors said. “In these individuals, we performed a categorical assessment (in men and women) of: scalp hair shape (curliness), color, balding and graying as well as (in men) of beard thickness (that is, density), monobrow and eyebrow thickness.” The gene identified for gray hair, IRF4 (interferon regulatory factor 4 gene), is known to play a role in hair color but this is the first time it has been associated with the graying of hair. “IRF4 is involved in regulating production and storage of melanin, the pigment that determines hair, skin and eye color,” the scientists said.

Homeopathy 

@LotusOak recomends to Download the First Aid Chart by @JoetteCalabrese

@LotusOak recomends to Download the First Aid Chart by @JoetteCalabrese Years ago as a young mother, I read that deaths in children occurred more often from accidents than illness. It was a pivotal moment for me. Fevers don’t kill, I learned, but a head injury could. Chicken pox might be uncomfortable, but it wasn’t going to maim my child like a burn or laceration. I deduced that there are only so many different kinds of dangers, so to learn which remedies to use ought to be something I could readily accomplish. Besides, I already knew that it was best to leave a fever alone and how easy it is to reduce chicken pox itching with homeopathy. Thus, I pointed myself in the direction of first-aid study for the next many months. How freeing! I set my mind to studying how to treat lacerations, shock, heat stroke, burns, head injuries, even electrocution, using homeopathy. This allowed me to focus my time on what was most valuable in order to become a more effective parent.

Dental Regenerative Fillings

Scientists Develop Regenerative Fillings from Stem Cells.

Scientists Develop Regenerative Fillings from Stem Cells. New research in the field of stem cells has yielded regenerative dental fillings that could keep working after they are put in. This effectively would eliminate the need for root canals as the stem cells encourage dentin growth, which basically means the teeth start healing themselves.
