Representación actual y antigua de los habitantes de Peking (Beijing)
Sitio del Hombre de Pekin
China es una tierra antigua, donde el hombre ha evolucionado desde sus orígenes mismos.
Es una historia rara,caso único de enorme país unificado por más de 2000 años.
Por eso siempre ha atraído la curiosa atención de los viajerosy del mundo entero.
Es un sentimiento especial, ya experimentado por Teilhard de Chardin, y por otros viajeros.
El punto omega teihardiano, está en la base de la vetusta tradición china, que ha planteado diversas fronteras para la relación entre el hombre y su esencia profunda.
El Tao que puede expresarse no es el Tao permanente.
El nombre que puede nombrarse no es el nombre permanente.
El no-ser es principio del Cielo y de la Tierra; el ser, de los infinitos seres es madre.
Por eso con el permanente no-ser se contempla la esencia escondida (del Tao); con el permanente ser se contemplan meros indicios del Tao.
Estos dos (no-ser y ser) tienen el mismo origen aunque diferentes nombres; tanto al uno como al otro puedes llamarlos misterio. Misterio de los misterios llave de toda mudanza.
Manejo de Ideas contradictorias
Desde las remota antigüedad en China han interactuado el cielo y la tierra. El cielo pertenecía al Yang, así como el número impar, y la tierra al Yin, así como el número par.
El Yin y el Yang son los dos principios que rigen la antigua filosofía china. El Yang es el principio masculino, activo y positivo, y el Yin, su contrario.
Palabras que resuenan
Para que las palabras lleguen hasta el fin del universo,las han dejado grabadas en los sonidos sempiternosde una enorme campana.
Grabaron allí los proverbiosy las frases más selectas que los sabios concibieron.
Aunque el lenguaje es oscuro,y afectados por el tiempo,los símbolos son misterio, cuando timbra la campana,se escucha la voz del cielo
Campana del Templo de la Gran Campana (Dazhong Si)
Representación de Confusio en el templos de su nombre (Kong Miao)
En la ciudad de Tai Shan, provincia de Lu, vivía una pareja que no había podido concebir un hijo.
Un un día, mientras la mujer peregrinaba a la Montaña Sagrada, un Ch’i-lin (Unicornio) se le apareció en medio del camino, se arrodilló ante ella, y de su boca brotaron unas tiras de papel con leyendas que decían: "El hijo de la montaña de cristal, la esencia del agua, perpetuará el reino caído de Chu y será un rey sin corona.“
En ese momento se encarnó la vida en el vientre de la mujer, y después de nueve meses, dio a luz a un hijo llamado Kung Fu Tse, más conocido como Confusio.
Las nobles huellas del tiempo
Esas arrugas profundas, tenaces y duraderas, han visto a muchos sabiosPasando por estas tierras diciendo cosas bellas del árbol que las lleva
A más de un ignorantele oyeron ellas decir que estas maderas viejas deberían quemarseo convertirse en mesas
Nosotros que ahora pasamos fugaces por su verapensamos que bien vale dedicarle este poema que celebra a los hombres sabios que dejaron que vivieran
Vetustos testigos de ideas que están escritas en piedra y que como los templos que las guardan, a veces se abandonan, pero vuelven y, transformadas, se renuevan
El armonioso diseño de las formas aparece por todas partes y se refleja en la poesía de los nombres

DEAD RIVER, RIVER OF LIGTHS
Tales of a urban river
I used to be meandering free and clean,but the city needed my ways,straightened my sluggish curves and burdened me with waste and refuse.
I served it well and finally died, and now the city, gratefulcelebrates with Christmas lights,and though I let them cover me with them,
and I look fine, I still hope for the daywhen they will not needartifices to admire me, and when I get to be alive againand appreciated simply as I am.
MORAVIA, FROM WASTE MOUNTAIN TO BARRIO
The brave people
They came from the country side attracted by the tempting cityor running away from the ward lordsor dreaming with a new world
Here they found a placeamidst the rubble and the smellswhich they proudly called homeand the waste was gold for them.
LA PRADERA, A COMPLEX SITE
The author, working for INDISA S.A., acted as a consultant for the direction of planning of the Empresas Varias de Medellín in 2004.
This entity has the responsibility for the handling of the solid wastes for the city of Medellín and for some of the neighboring municipalities of this area of 3 million people.
At the present time more the 700.000 annual tons of waste are taken to the site of La Pradera, located in very rainy location (3.000 mm of precipitation per year), with complex in topography and very far away from the sources of the waste.
One of the theoretical attractives of this site was that a rail track links it with the city… but rail tracks are currently mostly out of use in the zone.
LA PRADERA, A COMPLEX SITE
My daily journey
This is the road to the Prairie.I go there in my powerful truck loaded with refuseso that the wasteful peoplemay have their house in order and the dirt away from them.
I also forget about the waste,and forgive the smells,enchanted by the viewsand by the green mountains that adorn my ways.
REWAS 2008October 12-15, 2008 – Cancun, Mexico
LA PRADERA, A COMPLEX SITE
Indeed a Prairie
The new land fill sitedeserves the name it has,because of the green beautiful lands. But the city cares little to admire,all this is far, far awayand people are busyand do not have much time for poetry or similarwastes of time.
LA PRADERA, A COMPLEX SITE
Perhaps too much beauty is taken by granted and make people unable to observe details and to keep it alive and thriving
LA PRADERA, A COMPLEX SITE
Waters all around
Water is so plenty
and the mountains so generous with them,
that we think
that they are eternal
or disposable,
or defiant,
so we proceed
to waste the streams,
taming and humbling them
with careless deeds.

Diciembre de 2009
Ya en el aeropuerto de Narita sentimos el espíritu de bienvenida de este acogedor país
Bosquejos arbóreos
Los bellos árboles invitan al recuerdo, al bosquejo, al sentimiento.Lo que se siente con los ojos y con las manos se siente más verdadero.
La guerra y la paz
Cansados de la guerradejaron que los murosse embellecieran.Se murió el orgulloasesino y violentoy brotó, cual rama de olivo,un árbol esbeltoen lo alto del murocomo testigo.
El muro de la guerradivide inspirado por el miedoEl árbol de la pazune y el miedo se va muriendo.

The role of poetry and images in creating
recycling and resources saving awareness
Enrique Posada RestrepoINDISA S.A.
[email protected]ín, ColombiaSeptember 2009
New methods are required to create a more conscientious attitude towards recycling and resource savings, which can be used in education and in motivational activities.
This talk suggests a new approach based on the idea that the mind works in two levels of awareness and that the individuals and the human groups will act according to their belief systems, created in these two levels.
A NEW APPROACH (1)
The current educational framework is too much based on the logical mind and on the experiential basis for reasoning and arguing.
The new method proposes a more poetic, artistic, imaginary approach, so that the analogical mind will clearly be part of the learning and training process
A NEW APPROACH (2)
With this, it is expected that two major belief systems will support committed action in the environmental front from the individuals and the groups:
• The logical, experimentally supported system.
• The idealistic, poetic, visionary, creative, belief system.
A NEW APPROACH (3)
There was a great North American poet who gave rise to a literature current that opens consciousness towards nature: Henry David Thoreau.
He was inspired to write its classical poetic work, Walden, in 1854, which has also inspired many people.
POETRY AND IMAGES (1)
As Edward Wilson said
“Henry David Thoreau was thought by many in his own time, and many in our own, to be an eccentric who escaped from the mainstream of real life in order to dream. He was the opposite of that. He understood intuitively what we now know in more concrete and objective terms, that humanity is a biological species and thus exquisitely adapted to the natural world that cradled us. Thoreau was the scientific observer and lyrical expositor who hit upon the power of this conjunction between science and the humanities”
POETRY AND IMAGES (2)
Nature writing is one of the major innovations of American literature, which also includes Rachel Carson, the initiator of modern environmental awareness.
POETRY AND IMAGES (3)
She wrote Silent Spring (1962), which brought environmental concerns to an large portion of the American public and spurred a reversal in national pesticide policy—leading to a ban on DDT and other pesticides—and to the environmental movement. It eventually led to the creation of the Environmental Protection Agency in USA.
Other significant figure is Ansel Adams, the American photographer and environmentalist, well known for his beautiful photographs of the American West and Yosemite National Park.
When first visiting Yosemite he wrote “the splendor of Yosemite burst upon us and it was glorious... One wonder after another descended upon us... There was light everywhere... A new era began for me."
POETRY AND IMAGES (4)
Leaves in first plane
When any lost leaf becomes legendary personagewhich attracts the verses of a poetand the loving glances of an artist, reaching therefore first planes in the busy agenda of life, the destructive rites of the proud and the ways of stingy menwill become beautiful images and songs that summon science and spirit. Thus Earth renders glory, she becomes immense and promisedunto those who deal with her with appreciation.
TOWARDS INTEGRATION AND ETHICAL BEHAVIOUOR
Drawing by Claudia Molina
THE APPLICATION OF THE METHOD Delight in manjar
Certain earthworm describes with her nose that that as well licks with her reverse. In her lucidity, she then always leaves one nourishing nut layer to pay backand therefore, what little serves for us,the very humble earthwormenjoys with affability,leaving in her route what she does not like,and that that we do like:that valuable fertilizer that makes beautiful the garden.

Una lección al pie del Partenón
El Partenón
El Partenón
En la parte más altade la bella ciudad,tu erguida estamparesiste la maldadde los destructoreshorribles y orgullosos.
Tus hijos de mármolson testigos de tu belleza, arquitectura eternaorgullo de ciudadesque proclaman tus valores universalessentidos y preciosos.
Atenea Promacoses ahora la belleza eternaque no muere;que es más fuerte que los cobardes señores de la guerra.
La cantautora
Sentada a la vera de la víacanta preciosas cancionesque ningún turista oía
Deteniéndome en mis afanesescucho su dulce vozque canta bellos romances
Cántame una canción tuya,le pido, con emoción,y ella me regala una.
Yo me quedo extasiado. ¿Qué más se puede pedirrecibiendo tal regalo?
Ella canta y se regalaviéndome tan admiradoy me canta más galana.
El gran Adriano
Hombre de fronteras,emperador escaso,uno de los cinco buenosemperador hispano, por acá dejó sus huellas.
Huellas de investigador,de viajero admiradoque pagó sus respetosa los pueblos conquistadoscon amor de constructor.
Por acá estuvo San Pablo
Conversación de hijo y padre
Papá, ¿por qué hay tantas religiones?No sé bien, será porque son muchos los aspectos de Dios.Y, ¿por qué no se ponen de acuerdo, no es un solo Dios?No sé bien, será porque no han tenido tiempo para conversar.Y, ¿por qué no tienen tiempo para eso, es que no es importante?No sé bien, será que todos andan en sus propios mundos.Y, ¿por qué andan en distintos mundos, no es esta una sola tierra?No sé bien, será que no caben todos en el mismo lugar en el mismo tiempo. Además, casi todos los que fundaron las religiones ya no están en la tierra. Además la gente no sabe conversar sobre estos temas porque se pone nerviosa.
A propósito de San Pablo, que estuvo predicando en el Ágora a los incrédulos atenienses sobre el dios desconocido.
Almas gemelas
¿Dos hermanasdos amigasdos compañeraso dos modelos que posan?
No los sabremos,pero están juntashermanadas por la piedracomo si fueran dos almas gemelas
El traje típico
Con colores vivacesse arma la esperanzala misma que danzaen el corazón de la patria.
La vibración se siente con los sones musicalesy los trajes altivosdan soltura a los sonidos
Las mujeres se lucencon la mano en la cinturay en sus miradas ardenel fuego y la hermosura
Leones de la puerta en Micenas

Mi espíritu de arqueólogoaficionado y furtivose despiertaal entrar a esta cueva.Por momentos vivosensaciones de aventurasposibles y atractivas.
Pero el tiempo apremia,solo soy un turistade medios limitados.Es muy oscura la cuevay con los miedos vivosensaciones de locurasimposibles, prohibidas.

8th International Conference on Air Quality - Science and Application in Athens, 19-23 March 2012.
Laboratory emission sampling in a diesel motor bench. Motor (ISUZU 4JA1 Type I turbocharged, rotating pump direct injection, 2499 cm3, four cylinders in line, compression ratio 18.4, nominal power 59 KW at 4100 rpm)Fuel with three sulfur contents: 2,100, 500 and 50 ppmTwo different load conditions (4.75 and 24.0 kW), associated with two different motor rotating speeds.(1,770 and 2,420 rpm). Samples were taken with an isokinetic sampling unit capable of separating PM samples in three fractions (<2.5, 2.5-10, >10 microns).
Environmental sampling in a tunnel serving the Aburrá Valley regionConcentrations and samples of PM2.5 in the FERNANDO GOMEZ MARTINEZ tunnel were taken during complete 24 hour periods, at several times in 2010, in which there was certainty about the sulfur content of the diesel fuel used by the vehicles in the Aburrá Valley region. In this way the said three types of diesel fuel, with S content 2,100, 500 and 50 ppm could be correlated with the samples.
Environmental sampling in two sites in the Aburrá Valley regionTwo (2) PQ-200, BGI Instrument, (equipped with Teflon and Quartz filters) were placed two (2) zones of the Aburrá Valley [Instituto Politecnico Jaime Isaza Cadavid (Poli) and Universidad Nacional- Facultad de Minas (Unal)] in six (6) alternate measurement campaigns, with two simultaneous ones for both sites. Samples were taken during complete 24 hour periods, in such a way that they could be correlated with the ongoing changes in the diesel fuel S content (2,100, 500 and 50 ppm respectively). A total of 50 samples were collected in each area.
Analysis
In the three studies, samples were taken with Tefón and Quartz filters and subjected to chemical analysis in Laboratory Alpha in Colombia for metallic oxides and in the DRI (Reno, Nevada) for ions and carbonaceous species (EC and OC). Analytical techniques used were Spectrofluorometry, 3D Polarized Energy Dispersive X-Ray Fluorescence (Epsilon Model 5), for the determination of mineral oxides; ion chromatography (Dionex Model 3000) for the quantification of anions and cations; and the IMPROVE-A Thermal Method Protocol for the determination of organic carbon and elemental carbon.

PM 2.5 and sulfate in PM 2.5 concentrations diminish with lower S in diesel fuel for the samples taken in the urban areas.
CONCLUSION
A clear link was established between diesel sulfur content and PM 2.5 compositions and concentrations, which indicates the large influence of diesel fuel vehicles impact on the pollution situation in the region and the importance of this sulfur diminution. The impact is quite clear on the chemical PM 2.5 compositions which show a significant diminution of sulfates and ammonium salts.The impact on concentrations is detectable but is affected by the operational conditions of diesel equipment, vehicle age and operational practices.The impact was detectable in PM2.5 urban concentrations and sulfate salts in PM2.5

Global impact of metabolic CO2FACTOR UNIT VALUE
Estimated world population (2015) persons 7.311.390.000
Average CO2 generation by metabolism Kg/day-person 0,85
Total CO2 generation by metabolism Ton/day 6.231.414
Approximate CO2 generated in coal combustion kg/kg coal 2,20
Equivalent coal combustion to generate CO2 associated with average metabolism
Ton/day 2.832.461
Coal use in the world Ton/day 21.430.137
According to these numbers, human metabolism is in fact representative of the CO2
emissions (and more important to global warming) confronting it with the emissions from coal (and other fossil fuels) combustion.
Thus, any lowering of the CO2
human metabolic emissions will have a significant impact on global warming gases control.

Good habits and consciousness
Henry David Thoreau Rachel Carson
Ansel Adams“Henry David Thoreau was thought by many in his own time, and many in our own, to be an eccentric who escaped from the mainstream of real life in order to dream. He was the opposite of that. He understood intuitively what we now know in more concrete and objective terms, that humanity is a biological species and thus exquisitely adapted to the natural world that cradled us. Thoreau was the scientific observer and lyrical expositor who hit upon the power of this conjunction between science and the humanities”. Edward Wilson
BACKGROUND
116
Relaxed and empathic states
Farrel, D.J., The reduction in metabolic rate and heart rate on man during meditation, Energy Metabolism: Proceedings of the Eighth Symposium on Energy Metabolism, 1979
Ding-E Young, J., Taylor, E., Meditation as a Voluntary Hypometabolic State of Biological Estivation, Am.Physiol. Soc. News Physiol. Sci. Volume 13. June 1998
Wallace, R. K., and H. Benson. A wakeful hypometabolic physiologic state. Am. J. Physiol. 221: 795–799, 1971
WHAT TO DO
Relaxed State
Catecholamine levels drop
Galvanic skin resistance increases
Respiration rate and volume flow decrease
Decreased vascular resistance
Lowered O2 and CO2 consumption
117
While practicing empathic states, we reduce CO2 emissions, not only because the lower metabolism state, but also because of the activities promoted under these states
We present the following habits for lower metabolic CO2 emissions, either because they are closer to the basal metabolic rates or because they include empathic or relaxation practices
CONCLUSION
118
CONCLUSION
Listening to others with empathic attention• Changing the usual defensive and
offensive responses for: Recognition and appreciation no matter the other context
• The defensive response demand exited metabolic funtioning and excess of CO2 generation
Habits for lower metabolic CO2 emissions
119
Habits for lower metabolic CO2 emissionsCONCLUSION
Meditation and relaxation practices• When practiced in group have larger
impacts• This practices should be taught and
encouraged in the educational system and institutions and companies
120
Habits for lower metabolic CO2 emissionsCONCLUSION
Conversation and sharing• Friendship, family life, small communities,
communal activities, enriched by empathic attitudes
• The opposite to this: WAR associated with major environmental disasters and violence: excitec metabolic states and CO2 emissions
• Sustainable cities must be pleasant and peaceful
121
Habits for lower metabolic CO2 emissionsCONCLUSION
Conscious writing, representing, art work and reading• This will create self-esteem, self-reference,
leadership and a sense of compromise• Creation of city narratives and memories
enchance healthy pride• Stimulation of good cultural habits that all
sustainable citizens can enjoy and practice
122
Habits for lower metabolic CO2 emissionsCONCLUSION
Improving food consumption habits• According to Schwarsera, eating beef
has the highest GHG generation, with 22,6 kg CO2-eq/kg. Including different protein sources in the diet would reduce the CO2 emission in digestion
• Minimizing food waste, by purchasing, cooking and eating only the necessary.
• Eating slowly and in a conscious way
123
Habits for lower metabolic CO2 emissionsCONCLUSION
Additional habits• Diminish, separate, recycle and reuse
waste.• Seek rational use of water and energy
in every human daily activity • Seek changes in the smoking of
tobacco (and marihuana), or entirely avoid them, as these are bad habits generate huge amounts of CO2
• Understanding activities in term of their impact on CO2 generation and having them in the collective and individual mind as indicators of commitment with sustainability
