consumers will soon be able to use lithium-ion batteries even in their electric cars. Valence Technology, a United States-based firm has introduced Saphion lithium-ion battery for hybrid cars. Saphion boasts of the same energy-packed property of lithium-ion batteris used widely by mobile devices, without the hazards of cobalt oxide, which is highly explosive when punctured.
Confocal imaging, invented by Marvin Minsky in 1955, is based on the principle that the scanned beam can be manipulated in three dimensions (x,y, and z axes) and filtered back through a tiny aperture so that three-dimensional objects under very high magnification remain in sharp focus because they are not blurred by light bouncing back at different angles from different depths. confocal imaging has tremendous application in medical and scientific or industrial imaging where a combination of high mignification and high resolution are desired.
bar code 
we purchase and do you know that Norman Joseph Woodland and Bernard Silver are often credited as the original inventors of the bar code, which they patented on October 20,1949. though Woodland and Silver pioneered the concept of a symbol and a reader, it was not until 1974 that the first uniform product code (UPC) barcode was actually used in a supermarket.

a plant’s health is usually judged based on the leaf’s appearance. what if you can do more than just telling if the plant is disease free?
researchers from Illinois in the United States developed a field-based optical sensing system that depicts plant health using rapid pulses of polarized light. the researchers dubbed their invention, the N-checker could help farmers determine how much fertilizer to apply in real time. this could decrease crop production costs and dramatically reduce algal blooms. the tractor-mountable system works on corn, spinach, and other crops by picking out minute differences in leaf color. researcher Stee Finkelman of the containerless research said that with the technology, "we are able to easily see what is hidden from conventional instruments. the system eliminates interference from light reflected at a leaf’s surface and allows us to see light reemitting from within." depending on the plant, the leaves reflect, transmit, and absorb varying amounts of light, explains Finkelman. the depolarized light reveals nitrogen content and other properties that the sensors in the n-checker can detect. changes in nitrogen levels alter the way light interacts with the molecules in the leaf, affecting the spectrum of light that reemits from the plant. unlike other devices, the n-checker uses two red-light sources that can differentiate between the several types of chlorophyll molecules and thus reveal nitrogen-dependent plant health information. Finkelman said that devices that use both red and infrared wavelengths”tend to be imprecise, because they measure bulk chlorophyll content, which can result from a number of factors." the researchers also see opportunities for this technology in the detection of potassium, phosphorous, and other nutrients.

rain since this past few days makes the holy week invisible.
i don’t feel the ambiance of the holy week this year because it keeps on raining and indeed very cold especially on nights. though it gives me a good night sleep…
in fact, i wasn’t able to use the fan last night because it was really cold until this morning…
this kind of weather also doesn’t fit summer. there’s no way to have sun bathing and too cold to go for resorts. so those who are planning to go for beach and wants sun, just wait. mr sun’s gonna come out soon!
be safe everyone!!!
time for summer vacation now!
at long last i’m done with my first semester in nutrition and dietetics but still a lot of works to face on the following years.
but what matters most now is the vacation time…it’s time for the students to relax, pamper themselves and get over all the pressures experienced in school.
mura ko ug naibtan ug tunok after my last exam this morning. but before that, i was very pressured and stressed last night and this morning. i wanted to study but i couldn’t. many things were bothering me that i can’t even understand a word i was reading.
but after my exam and also my defense by the way, i was feeling heaven already. to all the students out there who’s not yet done with the school works, you’ll get over it soon…
happy vacation everyone and happy easter!!!
