El agua es el principal componente del cuerpo humano y es indispensable para la vida. El cuerpo está compuesto de un 60% de agua, la cual se encuentra tanto dentro como fuera de las células. El organismo pierde agua constantemente y debe reponerla a través de la ingesta de agua para evitar la deshidratación. La molécula de agua está formada por un átomo de oxígeno enlazado a dos átomos de hidrógeno, lo que le da propiedades polares y la capacidad de formar enlaces de hidrógeno
Budwigs interview
Lothar Hirneise : What is your fundamental research?
Dr Johanna Budwig: In 1950, I developed Paper Chromatography of fats. With this technique for first time fats, fatty acids and lipoproteins could be detected directly even in 0.1 ml of blood. Using Co 60 I was successful in producing the first differential reaction for fatty acids, and via radioiodine producing the first direct iodine value. I also developed control of atmosphere in closed system by using gas systems which act as antioxidants. Coloring, separating effects of fats and fatty acids were further developed. Behavior was studied in blue light, red light with fluorescent dyes.
I studied the electrical behavior of the unsaturated fatty acids with their “halo” using dyes with rhodamine red. With this technique I proved that electron rich highly unsaturated Linoleic and Linolenic fatty acids (found abundantly in flax oil) are the undiscovered decisive fats in respiratory enzyme function that Otto Warburg could not find. I studied the electromotoric function of pi-electrons of the linolenic acid in the cell membranes, for all nerve function, secretions, mitosis, as well as cell breakdown. I also examined the synergism of the sulfur containing protein with the Pi-electrons of the highly unsaturated fatty acids and their significance for the formation of the hydrogen bridge between fat and protein, which represent “the only path” for fast and focused transport of electrons during respiration.
This immediately caused a furor. Cancer problem was brought in. Hydrogenated fats, which includes all Trans fatty acids proved to be respiratory poisons. This was extensively published in 1950 in many journals including “New Directions in Fat Research”.
Lothar Hirneise : What is the prime cause of Cancer?
Dr Johanna Budwig: In 1928 Dr. Otto Warburg proved that all normal cells have an absolute requirement for oxygen, but cancer cells can live without oxygen - a rule without exception. Deprive a cell 35% of its oxygen for 48 hours and it may become cancerous. Dr. Otto Warburg has made it clear that the root cause of cancer is oxygen deficiency in the cells, which creates an acidic state in the human body.
He also discovered that cancer cells are anaerobic (do not breathe oxygen), get the energy by fermenting glucose producing lactic acid and cannot survive in the presence of high levels of oxygen. Long back in 1911 Swedish scientist Torsten Thunberg postulated that sulfur containing protein (found in cottage cheese) and some unknown fat is required to attract oxygen in the cell. This fat plays a major role in the cellular respiration. For nearly half century scientists were trying to identify this unknown and mysterious fat but nobody succeeded.

Orchestrating Docker - Making the Whale DanceJames Turnbull
Docker hit the developer scene in a big way last year. It made it easy for developers to run their applications locally and easily share and deploy them. But it wasn't quite ready for prime-time. It wasn't easy to run n-tier applications locally, manage Docker across different geographical locations or cluster Docker for availability and performance.
Recent releases of Docker have introduced new capabilities and tools to help with these use cases. In this session we're going to look at these new capabilities including:
* Looking at Docker Compose for building n-tier Docker applications and managing application stacks.
* Introduce Docker Swarm which provides orchestration and clustering for Docker servers.
* See how to integrate Docker and service discovery tools.
By the end of the session, you'll have a good understanding of how to take your Docker implementation to the next level and make use of these new capabilities.
This is a presentation of the ‘Air quality in Europe – 2013 report’. The report presents an overview and analysis of air quality in Europe from 2002 to 2011. It reviews progress towards meeting the requirements of the air quality directives and gives an overview of policies and measures introduced at European level to improve air quality and minimise impacts. An overview of the latest findings and estimates of the effects of air pollution on health and its impacts on ecosystems is also given
en esta diapositiva se presenta la naturaleza polar del agua, el agua corporal y su clasificación el balance hídrico, las moléculas del agua y su subdivisión etc...
2. El agua es el principal e
imprescindible componente del
cuerpo humano. El ser humano no
puede estar sin beberla más de cinco
o seis días sin poner en peligro su
vida.
¿QUÉ ES EL AGUA?
3. El cuerpo humano tiene un 75 % de agua
al nacer y cerca del 60 % en la edad
adulta. Aproximadamente el 60 % de este
agua se encuentra en el interior de las
células (agua intracelular).
5. En las reacciones de combustión de los
nutrientes que tiene lugar en el interior de
las células para obtener energía se
producen pequeñas cantidades de agua.
Esta formación de agua es mayor al oxidar
las grasas - 1 gr. de agua por cada gr. de
grasa -, que los almidones -0,6 gr. por gr.,
de almidón-
6. El agua producida en la respiración
celular se llama agua metabólica, y
es fundamental para los animales
adaptados a condiciones
desérticas.
7. Si los camellos pueden aguantar meses
sin beber es porque utilizan el agua
producida al quemar la grasa acumulada
en sus jorobas. En los seres humanos, la
producción de agua metabólica con una
dieta normal no pasa de los 0,3 litros al
día.
8. el organismo pierde agua por
distintas vías. Este agua ha de ser
recuperada compensando las
pérdidas con la ingesta y evitando así
la deshidratación.
9.
10. La molécula de agua está formada por dos
átomos de H unidos a un átomo de O por
medio de dos enlaces covalentes. El
ángulo entre los enlaces H-O-H es de
104'5º. El oxígeno es más electronegativo
que el hidrógeno y atrae con más fuerza a
los electrones de cada enlace.
ESTRUCTURAS Y PROPIEDADES
DEL AGUA
11.
12. El resultado es que la molécula de agua
aunque tiene una carga total neutra (igual
número de protones que de electrones ),
presenta una distribución asimétrica de sus
electrones, lo que la convierte en una
molécula polar, alrededor del oxígeno se
concentra una densidad de carga negativa ,
mientras que los núcleos de hidrógeno
quedan parcialmente desprovistos de sus
electrones y manifiestan, por tanto, una
densidad de carga positiva.
13.
14. Por ello se dan interacciones dipolo-dipolo
entre las propias moléculas de agua,
formándose enlaces por puentes de
hidrógeno, la carga parcial negativa del
oxígeno de una molécula ejerce atracción
electrostática sobre las cargas parciales
positivas de los átomos de hidrógeno de
otras moléculas adyacentes.
15. Aunque son uniones débiles, el hecho de
que alrededor de cada molécula de agua se
dispongan otras cuatro molécula unidas por
puentes de hidrógeno permite que se forme
en el agua (líquida o sólida) una estructura
de tipo reticular, responsable en gran parte
de su comportamiento anómalo y de la
peculiaridad de sus propiedades
fisicoquímicas.
16. PROPIEDADES DEL AGUA
Acción disolvente:
El agua es el líquido que más sustancias
disuelve, por eso decimos que es el
disolvente universal. Esta propiedad, tal
vez la más importante para la vida, se
debe a su capacidad para formar
puentes de hidrógeno.
17. En el caso de las disoluciones iónicas los
iones de las sales son atraídos por los
dipolos del agua, quedando "atrapados" y
recubiertos de moléculas de agua en forma
de iones hidratados o solvatados.
18.
19. Elevada fuerza de cohesión:
Los puentes de hidrógeno mantienen las
moléculas de agua fuertemente unidas,
formando una estructura compacta que la
convierte en un líquido casi incompresible.
Al no poder comprimirse puede funcionar
en algunos animales como un esqueleto
hidrostático.
20. Gran calor específico:
También esta propiedad está en relación
con los puentes de hidrógeno que se
forman entre las moléculas de agua. El
agua puede absorber grandes cantidades
de "calor" que utiliza para romper los
puentes de hidrógeno por lo que la
temperatura se eleva muy lentamente. Esto
permite que el citoplasma acuoso sirva de
protección ante los cambios de
temperatura. Así se mantiene la
temperatura constante .
