Sara Lee has sold it's bakery unit to a Mexican company to the tune of
$959 million. Grupo Bimbo, Mexico's largest food company bought the
fresh baked goods division which includes 41 U.S. plants.

The Sara Lee Bakery in Hastings is part of the deal.

Along with Nebraska's 2 other Sara Lee facilities in South Sioux City
and Omaha.

A Sara Lee spokeswoman said Grupo Bimbo has no immediate plans to shut
down any of the facilities.

Grupo Bimbo said it will invest a billion dollars in the U.S. over the
next five years to add bakeries, upgrade existing plants and make
other improvements.

As long as Grupo Bimbo does not hire illegal aliens to work in these
bakeries located in the US and they follow all the laws they are subject to,
I'm missing why there is a problem. A lot of foreign companies have
purchased US companies and a lot of US companies have purchased foreign
companies. It's called globalization. Get use to it.

"The second law of thermodynamics is an expression of the finding that
over time, differences in temperature, pressure, and chemical potential
tend to equilibrate in an isolated physical system. It explains the
phenomenon of irreversibility in nature. The second law may be expressed
in many specific ways, but the first formulation is credited to the
German scientist Rudolf Clausius.

In classical thermodynamics, the second law is a basic postulate
applicable to any system involving measurable heat transfer, while in
statistical thermodynamics, the second law is a consequence of the
fundamental postulate which assumes that all accessible states of an
isolated system are a priori (equally likely). In classical
thermodynamics, the second law defines the concept of thermodynamic
entropy while in statistical mechanics, entropy is defined to be
proportional to the logarithm of the number of accessible states."

http://en.wikipedia.org/wiki/Second_law_of_thermodynamics

Apply this second principle to a system (culture, civilization,
epoch, Fifth World (Colombia, Venezuela, Equatorial Africa), First World
(Canada), ....)

Remember this word: IRREVERSIBILITY.

Colombia ----> Canada (No)
Canada ------> Colombia (No)

The different systems must be isolated.

Si pones whiskey y agua con hielo, el sistema se equilibra con agua y
whiskey frios y menos hielo. ¿Por que no se vuelve todo hielo?

La temperatura del espacio sideral es - 270ºC. Sin embargo el Sol existe
desde la creacion del mundo y sigue caliente a +6.000º C. ¿Por que no se ha
enfriado aunque sea un poco, si han pasado mas de seis mil años?

Finalmente si mezclas 100 gramos de agua hirviendo con 100 gramos de agua
helada a 0º C, lo que queda es agua a 50º C, en este caso, exactamente la
temperatura promedio entre 100 y 0 ºC

Muy claro. Aunque creo que muy redundante y no obedece a la navaja de Ockam. Es como si te preguntara cuánto son dos mas tres y me contestaras con una ecuación diferencial de segundo grado.

En resumen: ¿cuál es la temperatura final de la mezcla? Tú respondiste "cierto" cuando el pañuelo dijo que era 90 grados centígrados. ¿Es así realmente?

PS: Como yo siempre les creo a las autoridades, (magister dixit), hice la prueba en la cocina de mi casa. El resultado fué 50 grados, y no 90. Con un margen de error, claro.

Dije "Cierto" pero no es 90, es error, NO es verdad. Nadie se dio cuenta.
estan tan acotumbrado a creer que si les dicen -"Ponte en cuatro", es ponen
en cuatro.

Cualquiera que esta acostumbrado a creer esta jodido. Llevo años diciendo
que no crean a nadie, verifiquen. Este es un ejemplo de mentiras mias
(intencional, por cierto).

Verificar puede ser muy difícil, pero es mejor no creer en algo dudoso que
creer en algo que no existe.

Muy claro. Aunque creo que muy redundante y no obedece a la navaja de Ockam. Es como si te preguntara cuánto son dos mas tres y me contestaras con una ecuación diferencial de segundo grado.
En resumen: ¿cuál es la temperatura final de la mezcla? Tú respondiste "cierto" cuando el pañuelo dijo que era 90 grados centígrados. ¿Es así realmente?
*******************************************

No, por supuesto que no es así (y espero que los sitios que visitaste
te lo hayan hecho comprender).

Lo cómico, sin embargo, sera observar qué explicación idiota se sacará
de la manga esta vez el neonazi senil para "justificar" la estupidez
de su "cierto" a las boberías que el pañuelo escribió.

Te apuesto 3 contra 1 a que va inventar algo babosada como "lo dije
solo para comprobar si alguien checaba" o alguna burrada por el
estilo.

La verdad es que el pobre diablo no tiene ni puta idea de esto, así
como de otras muchas cosas de las cuales escribe nomás por no
aburrirse.

Verdad que eres ignorante. Lo que dijiste es que el sistema evoluciona al
nivel mas del componente mas bajo
Si pones whiskey y agua con hielo, el sistema se equilibra con agua y
whiskey frios y menos hielo. ¿Por que no se vuelve todo hielo?
La temperatura del espacio sideral es - 270ºC. Sin embargo el Sol existe
desde la creacion del mundo y sigue caliente a +6.000º C. ¿Por que no se ha
enfriado aunque sea un poco, si han pasado mas de seis mil años?
Finalmente si mezclas 100 gramos de agua hirviendo con 100 gramos de agua
helada a 0º C, lo que queda es agua a 50º C, en este caso, exactamente la
temperatura promedio entre 100 y 0 ºC
The 200 grams of water will stay to 90º C.
There are a mistake, it have been the sign minus.

Well, final temperature 10ºC

f = heat of fusion of the water, 80 (79,06) calories.

fm + m(t1+t) = m(t2-t), t1=0, t2=100, m=100,

80x100 + 100t = 100x100 -100t; 200t = 10000-8000;

"The second law of thermodynamics is an expression of the finding that
over time, differences in temperature, pressure, and chemical potential
tend to equilibrate in an isolated physical system. It explains the
phenomenon of irreversibility in nature. The second law may be expressed
in many specific ways, but the first formulation is credited to the German
scientist Rudolf Clausius.
In classical thermodynamics, the second law is a basic postulate
applicable to any system involving measurable heat transfer, while in
statistical thermodynamics, the second law is a consequence of the
fundamental postulate which assumes that all accessible states of an
isolated system are a priori (equally likely). In classical
thermodynamics, the second law defines the concept of thermodynamic
entropy while in statistical mechanics, entropy is defined to be
proportional to the logarithm of the number of accessible states."

Sara Lee has sold it's bakery unit to a Mexican company to the tune of
$959 million. Grupo Bimbo, Mexico's largest food company bought the
fresh baked goods division which includes 41 U.S. plants.
The Sara Lee Bakery in Hastings is part of the deal.
Along with Nebraska's 2 other Sara Lee facilities in South Sioux City
and Omaha.
A Sara Lee spokeswoman said Grupo Bimbo has no immediate plans to shut
down any of the facilities.
Grupo Bimbo said it will invest a billion dollars in the U.S. over the
next five years to add bakeries, upgrade existing plants and make
other improvements.
http://www.khastv.com/news/local/Sara-Lee-selsl-facility-to-Mexican-company-107008648.html
Time to stop eating any Sare Lee products.
As long as Grupo Bimbo does not hire illegal aliens to work in these
bakeries located in the US and they follow all the laws they are
subject
to,
I'm missing why there is a problem. A lot of foreign companies have
purchased US companies and a lot of US companies have purchased foreign
companies. It's called globalization. Get use to it.
Not, globalization is bad and false.

Hay un problema de castellano, frecuentemente uno dice "agua helada" a 0º C
y significa agua a 0º C. Pero uno dice "agua congelada" a 0º C y entonces
signfica "hielo" a 0º C.
El error es que helada se usa a menduo como sinónimo de muy frío, pero no
indica el estado sólido.

Al final de cuentas, la física del problema se redue a una línea
calor ganado = calor perdido
que nos de una ecuacion lineal en una incógnita (la temperatura final de la
mezcla).
El resto es algebra elemental: cómo resolver la ecuación.

Tambien puedes olvidarte del hielo y hacer el calculo como antes. Y entonces
al final tomas en consideración las 8000 calorias de fusion del hielo
[100*79.06 exactamente] en los 200 gramos de agua a 50º C.
8.000 calorias en 200 gramos correponde a una disminucion de 40 ºC en la
temperatura de la mezcla.
Entonces la solución final es 50 - 40 = 10 º C

Muy a menudo el procedimiento es correcto pero hay errores en los cálculos,

En ciencia uno debe ser muy preciso, aun asi existe muchas cosas que
confunden por no decir claramente de que hablan. Los gringos acostumbran
cambiar el significado de las palabars, patriota se convierte en Insurgente,
paramilitar se convierte en Freedom Fighter, pais amigo del Imperio se
convierte en Democracia.

En ingles hay un gran problema en matematicas, la palabra "field" pero es
facil de explicar. Un field es un conjunto con dos operaciones y unos tres o
cuatro axiomas. Pero tambien exiten los "fields of force" y "temperature
fields" (los field of force los ves en las peliculas de Star Trek, los
temperature fields los ves en los mapas de temperatura). Para un gringo
joven darse cuenta que el field algebraico es lo que llamamos números y sus
generalizaciones. El otro es una funcion definida sobre un espacio (cuyos
elementos generalmente se llaman puntos).

T.Schmidt
P.S. Si tiene inclinacion a la ciencia, leete los libros de Roger Penrose.
Si quiere ser económico, léete Einteisn Theory of Realtivity, por el abuelo
de Olivia Newon John (fue contemproaneo y amigo de Einstein, Olivia nacio en
Cambridge. En Maracaibo hay un ingeniero petrolero hijo de un famoso
matemático ingles que debe haberla conocido de niña. El otro dia me lo

Eso de sistema cerrado se eliminó hace casi cien años.
Esta claro que tus conocimientos estan fuera de siglo.

Aconsejo ler libros mas modernos, porque pensar con ideas obsoletas puede
ser mas peligroso que no saber.

Las ideas son como las esposas, hay que cambiarlas apenas comienzan a
arrugar.

P.S. El comatoso Arik no se quiere morir. Debe estar esperando que Castro
se muera primero. Dicen que los médicos tratan de matarlo, pero no lo han
logrado. Yo le doy la razón, uno debe patalear mientras pueda. Si se
recupera va meter presos a los médicos.

Not true, your thermo is incorrect. Go get an education.
T.Schmidt
"The second law of thermodynamics is an expression of the finding that
over time, differences in temperature, pressure, and chemical potential
tend to equilibrate in an isolated physical system. It explains the
phenomenon of irreversibility in nature. The second law may be expressed
in many specific ways, but the first formulation is credited to the
German scientist Rudolf Clausius.
In classical thermodynamics, the second law is a basic postulate
applicable to any system involving measurable heat transfer, while in
statistical thermodynamics, the second law is a consequence of the
fundamental postulate which assumes that all accessible states of an
isolated system are a priori (equally likely). In classical
thermodynamics, the second law defines the concept of thermodynamic
entropy while in statistical mechanics, entropy is defined to be
proportional to the logarithm of the number of accessible states."

Not, globalization is bad and false.
Bear in mind the second principle of thermodynamics.
Five systems with different levels if they are united, they will reach
the level of the lowest.
The systems must be separated.

Paseando por los Pirineos me perdí; pedí instrucciones a una anciana que andaba en un borrico y me respondío en un lenguaje ininteligible (supongo que sería aranés; entendía el castellano pero no podía hablar una palabra). Intenté el francés pero fué peor.
Traté de seguir las instrucciones y por supuesto que me interné mas en el bosque, y si no acierta a pasar un todo camino que nos recogió, todavía estaríamos dando vueltas y sustentándonos con setas y castañas.

Te hubieras quedado en los Pirineos comiendo setas y domesticando
osos.

Otra cosa que empieza a haber más y más en algunas partes de España,
por ejemplo, son gente que sí entiende y habla el español, pero que a
adrede no lo hace.
Por lo general son imbéciles que creen que de esa manera son más
independientes y/o independentistas, aunque no hablen bien tampoco "su
idioma".
