No, it was not the big gun
that brought you down;
it was old Lamarckian
who brought in the clown.

When not in use, a thing
degenerates into nothing;
once a rudiment,
it is a useless instrument.

The limbs of a reptile,
the coccyx of the tail,
Intramuros or Great Wall
are of no use at all.

Idleness and uselessness
are a duo in the art of waste;
great indeed is loss in disuse,
the grey matter's no excuse. ~

Reflection

Reflection

Painting by Leo Carlo R Rotor
Poem by Dr Abe V Rotor

Prize winner, Contest on Human Values through Painting
and Mural, Sri Sathya Sai Organization, Metro Manila, 2001

Reflection - two faces in one,
     in one's mind and heart;
of the past and the present,
     prelude to all art.

Reflection - the self and the other
     fellow, foe or friend;
in war and peace, want and plenty,
     humbles at the end.

Reflection - The Prince and the Pauper,
     and The Little Prince;
Les Miserables, Christmas Carol,
     one's life ever since.~

Test on Global Warming (True or False)

Test on Global Warming (True or False)

Living with Nature School on Blog

1. Biofuels are healthy to the environment and economy especially in underdeveloped countries.

Global warming sign

2. It is wise to store carbon waste such as from CO2 emission and coal waste deep into the earth; anyway fossil fuels have been kept in the bowels of the earth for millions of years.

3. Methane has higher impact in global warming than CO2 emission, which means that animal husbandry is a major generator of global heat.

4. Greenwashing is the practice pf making environmental promises favoring hype over substance, a disparaging term usually applied to corporations such as automakers that tout new hybrids but still peddle gas-guzzling SUBS and lobby against increased-mileage requirement.

5. The ozone hole is getting bigger above the equator because of increasing heat while the ozone above the poles remains intact.

6. The hottest in household energy savings is the replacement of conventional incandescent light bulb with Compact Fluorescent Light bulb (CFL)

7. Compact Fluorescent Lightbulb may cost 2 or 3 times more than conventional light bulbs but consumes only one-fourth of electricity; besides they last very much longer.

8. Planting trees, scientists tell us, is not a wise measure to curb global warming, because trees absorb the heat of the sun.

9. It is the light of the sun – not its heat – that is used to covert water and CO2 during photosynthesis to produce sugar and O2..

10. The US alone contributes 50 percent of the total annual CO2 output which is 32 billion tons.

11. Lead (Pb) poisoning can be obtained unknowingly from paints, prints, dyes, because lead is an excellent fixer. 

12. China’s economy has been growing steadily at an average rate of 10 percent in the last decade, thanks to its fast growing industrialization. 

13. Today’s CO2 in the atmosphere which is 379 ppm in 2005 is higher than anytime in the past 650,000 years. 

14. Of the 12 warmest years on record, 11 occurred in the last 20 years, mainly from 1995 to 2004. 

15. There is a new law in Japan that at least 40 percent of rooftops of building are green in the like of a high rise garden – similar to what we can aeroponics.

16. Total water on earth as ice and glacier is around 2 percent.

17. Chlorine, methane, ammonia, hydrogen sulfide contribute to acid rain. Acid rain and global warming have no connection to each other.

18. Asia is the last region to clean up its cities – Orientals are not as meticulously clean as Americans and Europeans. 

19. It is now accepted unanimously that industrialization is the culprit of global warming.

20. Global warming has something to do with the disturbance of the tectonic plates leading to more frequent and stronger earthquakes, tsunamis and volcanic eruption.

21. The effects of global warming are the concern of governments and big corporations because they have the power and resources to curb its effect. We, ordinary citizens, are but by-standers, but we should be willing to abide by the rules they set.

22. Penguins and white bears are drowning in the Arctic region because of the melting of ice.

23. Converting corn into ethanol requires more energy in the process than the net energy output/ produce.

24. The name Rachel Carson rings every time we talk about pollution, a subject in her book, “Silent Spring”,

25. An Inconvenient Truth is based on Earth in the Balance: Ecology and the Human Spirit is an international bestseller written by Al Gore, former vice president of the US.

Spanish system of volumetric measurement in the Philippines

Spanish system of volumetric measurement in the Philippines

Dr Abe V Rotor
Living with Nature School on Blog [avrotor.blogspot.com]

Dama Juana, (PHOTO) early glass jar was introduced by the Spaniards mainly for wine, like basi (Ilocos Wine). Its content is approximately 5 gallons - equivalent to that of common plastic jars today.The Spaniards introduced into the Philippines a practical system of volume (in lieu of weight) measurement which we used for almost 400 years. Some of them are still being used today.

This system applies mainly to agricultural crops - rice, corn, mungo, muscovado sugar, sesame, beans, flour of rice, corn and cassava, and the like. It is also used in measuring fish and fish products like ipon (dulong), dilis (dried anchovies), salt, suso (snail), padas (fry of samaral fish) and other small fishes.

The system consists of the following units, systematically patterned as follows:
  • cavan
  • ganta (or salop)
  • litro
  • chupa.
  • gantilla
 There are six chupa in a ganta (PHOTO), twenty-five ganta to make a cavan. There is also litro, equivalent to four chupa, and gantilla, eight of which is equivalent to one ganta. Except for the cavan which is made of jute sack, these measuring tools is made of wood having the same dimension on all sides and bottom.

Spain did not invent this system; it evolved in early Europe and Middle East, which in turn was introduced into the Philippines. Remember the story of Alibaba in One-Thousand-and-One Arabian Nights? The story tells how Alibaba's brother came to know of his secret of having found a treasure. A gold coin stuck at the bottom of a ganta!

How accurate is the system?

I remember old folks saying, it depends if you have "light hands" - meaning when measuring, say rice, pour the rice lightly into the ganta and run a lever quickly across its top to level it, so fast and light, it's like a sleight of the hand. The idea is to avoid compressing the content.

As a kid I tried the technique. It's true. Test it by measuring the commodity, compact it by tapping the ganta real hard on a solid surface. You will notice how the content "shrinks." That's how much you gain having the gift of "light hand". Which to some people is like having a Green Thumb.

But here is a malpractice of vendors. Place your thumb as deep as possible into the container, and while filling it up, discreetly elevate your thumb to create a space inside. This is done on commodities you don't have to use the level, like ipon, monamon, ariyawyaw, sapsap, padas - and other kinds of small fish. But culprits can't escape the watchful eyes of experienced customers.

The Spanish volumetric system was popularly adopted during the whole Spanish period in the Philippines, extending to the Commonwealth era and thereafter. It was phased out only recently with the introduction of the international Metric System.

However, we still use cavan today, now standardized to 50 kgs in weight. Fish is sold wholesale in bañera, fruits like mango are packed in tiklis, tomatoes and pomelo oranges in standard size wooden boxes. There are still ganta and chupa used in the market, and Filipinos being innovative, have alternative measurements duplicating the obsolete volumetric system. Del Monte can is approximately one ganta, sardine can for chupa, table glass for gantilla.

A dozen of eggs, please. Isang piling (sapad Ilk) na saging. Pinch of salt. Isang dakot na bigas. One cup of milk. A flock of sheep. A truck of gravel. One light year is 186,000 miles per second. Micron is one-millionth of a mete. How about nanometer? Megapixel?

Indeed measurements have evolved a long, long way. ~
------------------

With the metric system, Cavan is 75 liters, Ganta 3 liters, and Chupa 375ml.

Katuray - Queen of Asian Flower Vegetables

PUL-OY (Breeze)
San Vicente, Ilocos Sur, Philippines to the World Series
Katuray - Queen of Asian Flower Vegetables
Living with Nature Center

Dr Abe V Rotor

Katuray in Pilipino and Ilocano is scientifically called Sesbania grandiflora. "Grand flowers" indeed, immaculate white and shy, glisten in the sun.  Then as the day wears off, shrivel and fall to the ground, leaving clusters of blossom to open the next day, so in the next,  in succession through the amihan season until summer. Pods dangle like chime in place of the flowers. Angie Tobias 18, picks katuray flowers from the tree at the Living with Nature Center, author's residence at San Vicente, Ilocos Sur.  Photos taken by the author.

Flowers - in any stage, crescent to fully opened - are picked by hand or with bamboo pole, as often as daily during the flowering season. Young succulent pods, and in other countries young leaves, are also gathered as vegetables cooked into salad, diningding, for stew and broth- perfect with broiled fish, thickened in buridibud (kamote or sweet potato paste).  It's a typical dish of Asians, specialty Ilocanos. Move over culinary greats of the Western world. Author with newly harvested unopened katuray blossoms ready to be cooked into salad, cum fresh red tomato, a dash of salt or patis, with option to include sliced shallot or sibuyas tagalog.  Try this perfect side dish for lunch and dinner. 

Is Sesbania grandiflora, as grand as its name when it comes to its nutritional value? Why not?  Take a quick look at this approximate analysis per 100 grams, based on young leaves. Likely not far from flowers (author's note). 
  • Calories: Around 62 kcal
  • Protein: Approximately 7.7 g
  • Carbohydrates: Roughly 11.5 g
  • Dietary Fiber: About 3.3 g
  • Fat: Around 0.5 g
  • Vitamin C: Approximately 38 mg (about 63% of the recommended daily intake)
  • Vitamin A: Roughly 1130 IU (around 22.5% of the recommended daily intake)
  • Calcium: Approximately 130 mg
  • Iron: Around 1.2 mg
A glimpse on this set of data assures confidence on the Health Benefits of Sesbania Grandiflora, as food and natural medicine owing to these properties: Antioxidant, Anti-inflammatory, Anti-Helminthic, Anticoagulant,  Hypotensive, and others, and if I may add - Anti-Aging and Relax-Promoting. 

Author's:  A variant of Sesbania grandiflora produces shades of pink and purple colors. It  produce flowers year round, particularly in the rainy months when the white variety is virtually flowerless. Local folks say colored flowers are more nutritious, likely because of xanthophyll and carotene pigments.  Plant katuray on your backyard, and open areas as long as the soil is loamy, relatively fertile, and safe from flood.  Stick a branch into the ground and make it grow into a tree. Include katuray among the plants in the Bahay Kubo garden. ~

Old Bridge across Banaoang Pass

Old Bridge across Banaoang Pass

"You are a peacemaker and guardian, oh, bridge,
rather than a bridge of sigh;
You tame the wind, the river, and the mountains,
and countless passersby." avr

Old Bridge across Banaoang Pass in acrylic (60" x 41") by the author.

Past your golden age, three generations have passed,
     Once in your prime, and also was mine;
The world over the horizon across your span, I sought
     For dreams the sweet goal of time.

While across your other end leads to home, sweet home,
     For loyal sons and daughters in homage,
Returning to childhood memories, to peaceful repose,
     Gateway indeed you are to every age.

And in between, fleeting were the years, but never
     Lost - dream fulfilled, or never was -
Matters but little in your own world, bright and windy,
     As the sun rises through the Pass.

And if a lonely soul comes to your world, gazes around
     And high, the strength of the towering
Rocks, the sharp, gentle slopes of green and golden
     In their pristine - they're Nature blessing.

From the cliff down the ravine, the great divide
     Of the rugged Cordillera, surrenders
To a mighty river born in a fertile valley, gathers
     Strength as it flows and meanders.

You are their peacemaker and guardian, oh, bridge -
     And rather than a bridge of sigh,
You tame the wind; you tame the river, the mountains,
     And every day countless passersby.

Bearing their weight and their load uncomplaining,
     Their pain and joy of going and returning;
And seeing yonder farmers and fishers in their work -
     All’s well ‘til the sky sent the river roaring.

Now it is your time to rest, the wind, river, and mountains
     And I, to bid you goodbye in the setting sun;
But your ruins rise a monument seen by all & from Above,
     Where once a boy with dreams crossed your span. ~

Painted for Dr Laurence (Rencie) Padernal), April 29, 2012. Presentation and unveiling of the painting to the birthday celebrant Quirino Bridge is named after President Elpidio Quirino, a great Ilocano leader. It spans across the mighty Abra River passing through Banaoang Pass, and joining the towns of Santa and Bantay both in Ilocos Sur province. The bridge survived a recent strong typhoon but was soon retired and replaced by a new bridge. Its beauty however, cannot be equaled.

Exuberance of youth meets sunset on the edge of Banaoang Pass, as 
the Cordillera turns to amber and the Abra River to emerald. ~
