Honestly, hanggang ngayon masama pa din yung loob ko. We used to have a TP4 Scholar taking up Chemical Engineering. Since alam ko kahit papano, ako yung nag-influence sa kanya na kunin yung course, I took the responsibility of personally providing him all the help that he needed. Unfortunately, bumagsak sya. Binagsak nya ang favorite subject ko. Yes, bagsak sya sa Stoichiometry.

Nakakainis, actually hindi lang sa scholar na ito ako disappointed. Pati dun sa mga anak ko. Lahat sila tunuran ko ng Stoichiometry. Pero lahat sila binagsak pa din yung subject. Nakailang takes pa bago naipasa.

Ewan ko. Actually confident ako magturo ng subject na ito. Favorite ko nga kasi to. Pareho naman ang ginagawa ko sa mga tinuruan ko. Tatlong ways of solving pa nga yung tinuturo ko eh.

Yung una kung pano sya inexplain nung prof. Parepareho kami ng Stoich Prof. Kaya sigurado ako, maayos nauturo ang subject na ito kasi tried and tested ko na yung prof na yun. Favorite Prof ko din kasi sya. Kaya alam ko kung pano nya ineexplain yung theory at yung technique sa pagsosolve ng problems.

Yung pangalawa eh yung special techniques ko in solving. Binigay ko na lahat as in step by step kung pano ko iaanalyze yung problem. Ano yung mga Rule of Thumb na naformulate ko on my own. Lahat na ibinigay ko nah.

Yung pangatlo eh yung engineering way of solving it. May mga x and y na nagaganap at gumagawa ng equations. Para in line with the engineering way of analysis.

Basta sa point of view ko, naibigay ko na lahat pero ewan ko ba bakit parang hindi pa sapat yun para makapasa sila. Para kasi sakin, ang simple simple na nung topic:

Mass in equals Mass out

It doesn't get more simple than that.

Binago na nga din yung syllabus to incorporate yung Mass Balances na ginagamit dun sa mga Unit Operations subjects in higher years for chipipay points wala pa din. Kaya isa lang talaga ang napagtanto ko. Estudyante na ang may problema dito.

Lagi kong sinasabi ang learning ay may tatlong base factors lang:

Student. Teacher. Subject Matter.
Given na parepareho naman kami ng teacher. Given na ang Subject Matter ay the pinaka-basic basic of all the basic of the basic Chemical Engineering Subjects. Kya Conclusion. Estudyante na talaga ang may problema dito.

Di ko alam kung pano sila nakasurvive without developing yung analytical skills nila. In all honesty, di mo naman kelangan magreview sa Stoich eh, basta bear in mind lang yung napag-aralan sa Analytical Chem at Gen Chem like balancing, stoichiometric factors, concentration writing, etc. Nakapasa naman sila dun. kaya di ko magets kung bakit kelangan dibdibin yung pag-aaral.

Di naman din literal na yung numbers na lumabas sa exercise ganun din lalabas sa exam. It just shows na you nee dto understand the problem first and then think of a way to solve it. Di naman yun ibibigay kung walang solution eh.

Kaya para saken invalid yung reason na Di ako nakapag-aral o kaya Di naman binigay na example to eh. In real life naman kasi wala naman sample problems na eksakto. Pwede mo lang gawing guide pero word for word the same. Wala. Sinabi ko to dati sa mga estudyante ko na scholars sa UST:

"Kung di mo kayang dalhin sa TALINO, Dalhin mo sa TIYAGA.
Kung di mo kayang dalhin sa TIYAGA, Dalhin mo sa TALINO"
And I do believe it applies here.

When I was a kid, I used to fear the unknown. I am a big scaredy cat. I was afraid to be alone in a room at night, I was afraid to watch horror movies, and most of all, I was afraid of the dark.

As time passed by, I overcame these petty fears. I developed confidence, and made a name for myself with my leadership skills, although in limited areas.

But going back to the subject of fear. I learned these passed days that fearing the unknown is nothing compared to fearing an oncoming catastrophe that will change the lives of Filipinos.

I was simply blog walking that Tuesday evening when a student-leader from my alma mater posted this link. It was news article concerning the never ending issue regarding the Oil Depot in Pandacan.

Apparently, the City Council of Manila passed a new ordinance that amends a portion of Ordinance 8187. If you will remember, Ordinance 8187 was the controversial draft ordinance 7177 which Mayor Alfredo Lim signed in the Oil Depot Compound last 2009. It aims to let the Petrochemical Industries to continue their operations in the Pandacan area. But the New ordinance reclassifies the Pandacan Oil Depot Area from High Industrial to Highly Commercial/Mixed use area. Please read this section that I took from the news article:

In Section 1, Section 2 of Ordinance No. 8187 shall be amended to read as follows: “The land use where the existing industries are located, the operation of which are permitted under Section 1 hereof, are hereby classified as Industrial Zone except the area where petroleum refineries and oil depots are located, which shall be classified as High Intensity Commercial/Mixed Use Zone (C3/MXD),” the ordinance stated.

Well I won't flatter myself with the thinking that they must have read my blog article before, since they countered my ultimate counter-statement regarding the change of the Pandacan area from Industrial to Commercial Zone. I mentioned in my blog that the reclassification will not only eliminate the Oil Depots, which most people think as "toxic", but also the "non-toxic" industries in the area that provides employment to residents in the vicinity. Bear in mind that I wrote that particular blog article when I was still a 5th year Chemical Engineering Student.

I am writing this series of blog articles to express my sentiments in this move by the City Council of Manila. But before someone points out that I am just a blogger, I would like to explicitly say that I am a licensed Chemical Engineer. Inexperienced and also not part of the Petrochemical Industry, but I much more credible that a person who doesn't have education with regard to this subfield of Chemical Engineering.

I intend to create this Economic Timebomb Series as a continuation of my earlier blog post about this issue. Of course, from that blog, you can easily conclude that I am against to remove the oil Depots in Pandacan. With this series I will attempt to explain in different aspects why this move is illogical and will have catastrophic effects in our economy.

Fuel prices will go up!

That was the thought that was shouting in my mind after I read news article. In future posts, I will provide a simple course in Physics and Engineering Economy that will explain in detail why fuel prices will go up. But for now let us consider this as a fact.

I immediately contacted my Junakis Jeco who is an economist. I asked him the question: What is the effect in our economy if there would be significant increase of fuel prices? Here is his reply:

Increase (in) price of basic commodities po. Then if (it) continues to increase, it can trigger large scale inflation. Kasi fuel(,) basic need to run an economy yan, kasi connected halos lahat ng industry jan.

My initial thought was cemented when I read his message. Of course he mentioned that he will try to study the issue because he thinks that it can still be prevented. But until he tells me convincing arguments that will change my mind regarding the forthcoming onslaught, I will stick to my instincts.

I concur to Jeco's statement that fuel is connected to almost all industries. In future posts, I would try to enumerate all if not most of the industries that will be directly affected, and those in the secondary level.

The news article also mentioned that the Supreme Court released a 56-page Resolution regarding the matter. I found the resolution online and to my surprise Impeached CJ Corona handled the case. He was then Associate Justice and CJ Reynato Puno was still at the helm of the Supreme Court. Well, this is yet another instance that I am quite happy with result of the trial to impeach him. Most of my future posts will be a response to this resolution by the Supreme Court. I would try to give my counter-arguments and commentary on the issues presented in the resolution. So I suggest that you read it too. Here's the link: http://www.lawphil.net/judjuris/juri2008/feb2008/gr_156052_2008.html.

I would also try to make commentaries on the individual Civil Cases filed by those concerned that was cited by the SC Resoultion; If I will be fortunate enough to get them.

This is it for now, but I am adamant that compelling the Oil Companies to relocate their depots will create a future catastrophe. And I believe as a resident of Manila, as a Chemical Engineer, as a Filipino, it is my social duty to inform the public of this incoming onslaught that will have a huge impact in our lives.

For Chemical Engineers and future Chemical Engineers, this is where our profession meets with economics, social responsibility, and politics. I believe that it is our duty to prevent this catastrophe from happening. Be informed. Be confidently informed, then spread the word. This is not just for you, this is for our society.

The end is near. An Economic Timebomb is set to explode before PNoy steps down by 2016.

I'm scared...

I'm terrified...

You can read the 1st part here.

Haru dyos ko! One year in the making ang sequel ng aking board exam experience! Wahahahha!!! Paxenxa na kasi for the longest time kasi wala akong time dahil nagwowork ako. Tapos ngayong bum ko, ni-indulge ko yung sarili ko sa pagsusulat ng mga maraming bagay. In short, ngayon lang ako nagkaron ng mood para isulat ito! Whahahahah!!!
Maraming salamat nga pala sa lahat ng nagbasa ng part 1. Sana nakatulong dun sa mga nagboard last year yung pinagsusulat ko.

Alright! Lesgehitowwwwwwwwwwwwwwwwwwn!!!

Okay, so sa last post ni-promise ko na ishe-share ko yung technique sa pagsasagot. Super simple lang nito. Gagawan lang natin ng procedure yung pagsasagot para time saving. katulad ng ang sinabi ko nung huli, oras lang ang kalaban mo sa exam.

Sa sobrang simple nito, para ka lang nagsisimba. Hahatiin mo lang sa Readings yung pag sasagot mo. Depende sayo kung ilan yung gusto mong hati. Pero ididiscuss ko yung procedure na ginawa ko.

Hinati ko sa apat (4) na readings yung pagsasagot ko. 1st reading. 2nd reading. 3rd reading. Homily. O diba mass na mass ang peg! Ang objective kasi natin eh mabasa mo yung lahat ng questions. Para mag-gauge mo yung amount ng time na gugugulin mo sa isang question. You have 6 hrs to answer 100 questions. Basically 3 minutes 36 seconds per question.

Explain ko naman yung apat na hati ng pagsasagot. Pinangalanan silang "Readings" kasi babasahin mo yung lahat ng questions. So yung apat naa hati means apat na beses kong naflip yung pages nung questionnaire.

Eto ang pakatandaan nyo sa exam: Kahit gano pa katagal ang igugol mong time sa isang number, one (1) point lang din yun sa bandang huli. Kaya nga ang objective natin eh masagutan mo lahat nung alam mong question para may SURE POINTS ka na. Dadagdagan mo nalang ng TENTATIVE POINTS.

1st reading. Dito, babasahin mo lang yung questions ng isang beses. Sagutan mo agad yung mga pagkabasa mo pa lang alam mo na yung sagot. Normally eto yung mga Identifications at Fill in the Blanks. Pero syempre wag mo lang i-limit dun katulad netong example:

If A = B and B = C, What is C2=AB?
a.	A	b.	B
c.	A or B	d.	None of the above

Syempre sa unang basa mo palang alam mo na kagad na C yung sagot. Panis diba? Maniniwala ba kayo kung sasabihin kong This is an actually board problem? Yes, this was a question nung nagtake ako.

IMPORTANT!!! Isang beses lang basahin ang question. Tapos pag nagfall sa mga scenarios na ito ang nangyari after mo bashain ang question, jump to the next item:
(1) Kelangan isolve ang sagot
(2) Hindi mo naintindihan yung question
(3) Hindi mo alam yung sagot
(4) Hindi ka sure sa sagot

Isang very very useful tip. Yung mga nasagutan mo sa 1st reading, ishade mo na agad sa answer card. Pwede mo silang gawing guide mamaya. Siguraduhin ang na ang isheshade ay ang tamang bilog...
>>>>>Icheck ang number sa questionnaire
>>>>>Hanapin yon sa answer card.
>>>>>I-point yung lapis sa bilog ng sagot mo na in-line sa number.
>>>>>Idouble check ulet yung number, importante to!!!
>>>>>Ishade na ang sagot.

Since puro bilog bilog lang kasi makikita mo dun sa answer card, nakakalito talaga, kaya idouble check lagi bago magshade. Ako na nagsasabi, mahirap burahin ang mongol 2. Pwamis!!!

Bilangin mo kung ilan itong nasagutan mo, lagay mo dun sa scratch paper mo kung ilan. Lagyan mo ng caption: SURE POINTS

Oh edi natapos mo na basahin yung 100 questions. Balik ka ulet sa simula.

2nd reading. Dito pwede mo na idigest mabuti yung mga questions. Babalikan mo na yung mga questions na hindi mo nasagutan. Dito masasagutan mo na yung (1) at yung ibang (2) scenarios.

Para malaman mo kung ano yung mga questions na wala pang sagot, gawin mong guide yung answer card mo. Yung mga numbers na wala pang shade sa tabi, yun na yun. Check mo yung number sa answer card, tsaka mo hanapin yung number na yun sa questionnaire

Yung mga nasagot mo din dito ishade mo na din, sigurado ka din kasi sa mga sagot mo dito. Bilangan mo ulet tapos iadd mo dun sa sure ka sa 1st reading. Nadagdagan na yung SURE POINTS mo.

End of questionnaire? Go back to start!

3rd reading. Dito na pumasok yung mga hindi mo nasagutang (2) dun sa 2nd reading tsaka yung (3) and (4) scenario questions nung 1st reading. Ganto sila sasagutan:

[1] By Epiphany - basahin lang ng basahin yung question, magugulat ka na lang bigla mo maalala yung sagot. This happened to me!

[2] By Trial and Error - Refer to the 21-gon diagonal example from Part 1. Hindi kasi ako sure, kaya madami akong ginawang trials bago ko nilagay yung sagot ko.

[3] By Back-Substitution - Parang ang unethical noh? Well, that's the downside of multiple choice. One of them is the true answer, you just need to use them all. Given na may oras ka. Dito pumapasok yung pagiging mabilis mo sa 1st and 2nd reading. Para magkaron ka ng oras gawin to.

[4] By Deduction - Mas kilala ito sa tawag na 50-50. Ang gagawin mo, tatanggalin mo na yung dalawang choice na sa tingin mo improbable. Pano mo malalaman? Instinct and Intuition. Pag andun ka na, magugulat ka sa reasoning mo. Basta alam mo, hindi pede yung mga sagot na yun. Magandang i-couple ito dun sa back-substitution. Para dalawa nalang yung i-ba-back-substitute mo.

[5] By Reading - Yes, you read it right! Pwedeng gumamit ng Handbook! At maraming information sa Handbook lalo na yung basic Process Control. DUn ko nakuha yung answers ko sa Process Control eh.

Magkakaron ka ulet ng ilang sure answers dito. Wag kalimutan idagdag yun sa SURE POINTS mo. Tapos bilangan mo din yung mga numbers na may sagot na pero hindi ka sure pero mataas ang chance na tama. Isulat mo din yun sa scratch mo with the caption: TENTATIVE POINTS.

Tandaan na mag-ingat sa pagsheshade ah!!!

Tapos na ulet? You know the Drill!!! Isa pa!!!

Homily. Eto na yung mga hindi mo talaga alam. Ginamit mo na yung 5 ways to get the answer sa last reading pero wa epek. Eto na ang chance mong magdasal at magtawag ng anghel para ilaglag sayo yung sagot galing heaven, o ng demonyo para ipukol from hell ang sagot. In other words, HULAAN MO NAH!!!! Dito na pumapasok yung Chamba factor!

GOGOGOGOGOGOOGOGO!!!

Bago ipasa ang papel. Tandaan ang SURE POINTS at TENTATIVE POINTS. Gawin ang pagkuha ng mga ito sa tatlong araw ng exam. Para makuha mo yung Theoretical Grades mo.

Tandaan ang Exam weights according sa Chemical Engineering Law IRR:
30% Chemical and Physical Principles
40% Chemical Engineering Principles
30% General Engineering Principles

At para makapasa, kelangan ang grades mo sa lahat ng exam ay greater than or equal to 50%, tapos yung average nung tatlo ay more than or equal to 70%.

i-solve ang iyong Theoretical grades - Sure Average at Tentative Average

Day 1 + Day 2 + Day 3
SP or TP	(0.3)	SP or TP	_(5)(0.4)_ 4	SP or TP	(0.3)
= SURE AVERAGE or TENTATIVE AVERAGE

Yung Sure Average yung sure na grade mo. Galing mo kung 70% na yun. Pasado ka na. Kung hindi umabot, Icheck mo ngayon sa Tentative Average. Assuming na tama lahat nung hindi mo sure pero mataas yung percentage na tama, magiging grade mo yung Tentative Grade mo. Pwede pang madagdagan yun kung magaling ka chumamba at tama yung mga hula mo. Pero generally, Lower Limit yung Sure Average, upper limit naman yung Tentative average.

Yung Day 2, 80 items lang nun samin kaya may correction factor na 5/4.

hmmmp... Sure Average ko ay 65.7. Tentative average ko ay 86.1.

Ang Grade ko ay...

In between ng dalawang yan! Whahahahahh!!!

Random tips!!!
- Icheck sa PRC kung pede ba gamitin sa Board exam ang Calculator mo. In general stringent sa Sharp brands. Ay meron nung nagtake ako hindi pinagamit ng Calcu nung 1st day! Kakaloka!
- Masterin ang Calcu na gagamitin. Stats, Calculus, solve function, equation function. Lahat na! Super helpful nya promise! Mas mabilis makapagcompute.
- Wag pag-aksayahan ng oras ang vague questions. Yung mga wala namang given sa problem pero pagdating sa choices may mga figures. Laktawan. Intayin ang announcement. Pag malapit na matapos ang time, i-treat as (3) scenario question.
- Iwasan sumagot ng letter E. Trick letter yun.
- Kumaen pag gutom. Pwedeng kumen pag nageexam. Ako nga Egg and ham clubhouse sandwich ang dala ko at Jungle Juice! Elementary ang Peg!
- wag kabahan!!!!!!!!!!!!!!!!!!!!!!!!!
- Kahit pinalagyan ng Bond paper yung Periodic table sa Likod ng hard cover ng Handbook 8th edition, wag nang magkabisado ng atomic weights. Pwede nyo itong makita sa Properties of Pure Substances Table sa Chapter 1.
- Mag-CR na bago magexam. Sayang sa oras kung mag-C-CR ka pa on the exam time.
- Wag nang mag-aral before the 1st day of exam and after the 1st and 2nd day. Magrelax. Matulog ng maaga. Walang idudulot ang pagcracram mo kundi kaba.
- Dumating ng maaga sa venue. Mas mawawala ang kaba mo.
- Wag nang magpapalit palit ng sagot. Nagiging sanhi yan ng pagkabagsak.
- Please read my article regarding the Legend of Uncertainty Principle: Totoo ba ang When in doubt, choose b or c'?

Finally na tapos ko din ang second part!!! woohoo!!! Goodluck Future Chemical Engineers!

Sigurado ako by now, may nakapagsabi na sayo yung technique na ginagawa nila pag multiple choice yung exam. Most likely, eto yun:

When in doubt, choose b or c.

Sinabi din to samin nung prof ko dati. Since yung sa board exam nga daw ay automated yung pagpili ng questions sa database. So automated din daw yung pag lalagay nung position nung Correct answer sa choices.

In an attempt to prove the theory na may preference yung pag-automate sa b and c na answer...
-Gumawa ako ng program na nagrarandomize ng number from 1 to 4. 1 represents a, 2 for b, 3 for c and 4 for d. Simulating yung correct letter of answer.
-I made it to simulate the board exam na gumagawa ng 100 questions.
-ni-simulate ko din na gumawa ng 50 exams yung program.
-Kinuha ko yung Mean, Median, at Relative Frequency Distribution per batch.
-1 batch = 1 run of the program
-I took 5 batches.

Eto yung source code: Click on the Text Area, press CTRL+A, then CTRL+C to copy the source code

Eto ang results...

Data

so ayan sa taas yung 5 batches ng data

Mean and Median

So as you can see, sa limang batches ng 50 exams, magkakalapit lang yung mean at median nung apat na sagot. Ibig sabihin walang preference sa b at c na sagot. halos pantay pantay lang yung incidence nung mga sagot.

Relative Frequency Distribution

In general, pinakacommon yung 21-25 number range for all choices. Pumapangalawa yung 26-30. Or baliktad dun sa iba. Pero pwede natin maconclude na mataas yung frequency from the 21-30 range. Population mean is 25.5, so safe assumption na 25 questions na ang sagot ay isa sa choices out of 100 questions. Tig te-25 ang a, b, c at d.

Conclusion
Walang katotohanan yung preference sa multiple choice na b and c sa board exam. Of course, ako kasi yung nagsulat ng program na ito at wala akong nilagay na segment na magkakaron ng preference sa choices.

Meron akong theory kung totoo man yung preference sa b and c. Pag hindi automated or manual yung pag sulat nung choices, ang mindset, itago sya sa gitna, which are b and c.

Eto yung human factor in making the exam. Akala lang ng tao random nya ginagawa pero subconsciously, may pattern syang nagagawa or yung mindset nga sa gitna ilagay.

Kaya kung totoo yung preference ng b and c sa board exam, in my opinion, hindi automated yung pag jumble nung choices. Malamang, random lang yung questions. Pero kasamang ini-input yung choices dun sa database. Kaya pag napili nung computer yung question, kung pano ininput yung choices sa database, ganun na sya i-a-output.

Isa lang ang paraan para maconfirm natin to. Kung ipapakita yung source code nung Question Randomizer na ginagamit for the board exam, matetrace kung meron ngang preference segment. Pero asa naman na ipapakita saken yun!

an excerpt of the Chemical Engineering journey of batch 2010 boys

Note: Gusto ko muna humingi ng paxenxa sa mga ChE 2010 boys. Wala lang kwekwento ko kasi yung part of our lives ng walang paalam. Wahahahhaha!!!

I was watching the 1st half of the anime series Shakugan no Shana 3 Final the other night, and I was touched by this particular scene in Episode 15. This is where the Great Flame Haze known as the Adamant Convoy, Samuel Demantius, and his Crimson Lord, Zirnitra the Aegis, made their farewells. Demantius acted as the decoy for the Flame Haze Army to escape to the Tendokyu. He single-handedly fought a whole army of Tomogaras while the rest of the army retreated. He was mortally wounded in the process. But before his final breath, he thanked his "brother-in-arms", Zirnitra, who has been his companion for six centuries and had fought together in the previous Great War. It was really touching. Being that Zirnitra is a Crimson Lord who resides in a different world and only manifest himself through the Cocytus, he is impervious to physical damage. He made his leave as to prepare for future wars, leaving Demantius to die in the place where their last mission as partners ended successfully.


Demantius
I am a member of different circles of friends. You can say I have many Brothers in Arms. But for this post, I would like to share my Brothers-in-arms during my life as a Chemical Engineering Student.

They say that you can know a person more in the battlefield than just sitting beside them. Whoever said these immortal words, I salute you. But of course let's not just isolate the world "battlefield" as a "warzone". I think that the word battle is simply analogous to "aggressive exchange". In war, it is the exchange of Trinitrotoluene powered weapons; Exchange of ideas in debates; Exchange of strategies in Trading Card games. You know what I mean. But during the period of my ChE student years, battle simply means Sentinel vs Scourge.

Defense of the Ancients or DotA was the first avenue where my now fellow Chemical Engineers and I became bonded. We developed a bond that started simply as an ally or teammate to win against the opposing team, then it grew to the friendship that we now have.

The first month of our college life was nearing its end. That was the time that some of the boys were already friends. I have a former classmate in our class that time so I was in their company. But when one of the boys asked me to join them in their game of DotA, I thought, "why not?".

I played my first DotA game with them in what used to be a Computer shop of the now Motorcycle shop below the Balay bar across the Engineering Building. It was then that I first used my Trump Character, Rylai Crestfall and the rest, as they say, is history. The history of our Chemical Engineering journey.

Since then, I have been in their company. We ate together in the then karinderia of the person we call as Mother after class, and then we played more DotA after meals. We played DotA to celebrate passing our exams; We also played DotA to relieve our stress of failing them.

The same thing happened when I was transferred to the "other" ChE section. DotA was yet again the instrument of successful communication with my new set of brothers-in-arms.

Through DotA I had come to know them more. Things that they would not normally show or tell in conversation, they constantly and unconsciously show during DotA battles. You can see those who are aggressive - excels in ambush, face off combat, greedy for first kill or most kill; those who are cautious - excels in defending, tag team partners, always with teleport scroll or boots of travel (i.e. me); those who are great support - party centered skill and build, wants a team win rather than most kill.

I also learned that they fall into these categories:

>>>>sore loser - very^inf bitter when his team loses
>>>>command center - one who barks orders to his team,
>>>>Die hard player - really serious when playing, normally a command center, then becomes a sore loser after losing
>>>>Casual player - enjoys the thrill of the game, enjoys smokes after every game
>>>>Bully Victim - VON
>>>>Bullies - Note: Plural. Always finds the time to bully Von in game.

One of the person I really bonded with did not graduate with us. After failing Chem 112 during the second semester of our 1st year, he did not continue the Chemical Engineering journey and went on the fork road to achieve his real dream. Well, our real dream. We both wanted to become teachers, and now he is one. An English teacher in their province. Well, for his students he maybe Mr. Co the English teacher, but for us, he is our DAGON WARRIOR, our brother in arms.

Because we play all the time, we have developed a secular lexicon for our everyday use. It is actually a mix of gameplay Jargon, as well as made up words that were given meaning because of certain events. I'm just going to list down notable ones.

Jaboy
Meaning: a unit of measure for something exponential in size
Use in sentence: I'm so hungry, I can eat a Jaboy sandwich
Etymology: Jaboy is actually a nickname of a brother in arms. It all started when his then dorm mate and our classmate told a story. Since they were in the same all male dorm, they did the erectile stretch machoism brag. Allegedly, Jaboy was the winner.
Dyosa Comment: I don't know, I'm not the type that peeks eh. That's not how I roll.

Gatiti
Meaning: short or small in size
Use in Sentence: Sayang! Nakatakas pa yung Gondar! Gatiti nalang buhay nun!
Etymology: It is in reference of the male genitalia in Filipino with the prefix ga- that means "same size".
Dyosa Comment: You be the judge why they connected the male genitalia with short.

Imba
Meaning: not balance.
Use in Sentence:Imba yung kalaban, ang lakas grabeh!

Use in Sentence:No! Chinuchupa ako ni Wilbert!
Etymology: Filipino term for Felatio. Reference from when Hesed exclaimed the exact sentence written above when I was using Pugna's Ultimate Skill against him. It was used ever since.
Dyosa Comment: AKin na lakas mo! Chupa!!! life-steal!!!

Ulti
Meaning: Ultimate Skill
Use in Sentence:Gamit na nang ulti dali!
Etymology: Every character in Dota has a fourth skill that can be accessed first after your character reach level 6. It is different for each characters.
Dyosa Comment: Might be the most shouted word ever in the history of DotA gaming.

crucial
Meaning: important
Use in Sentence:Ang crucial nung pagkabuo ko ng butterfly, dun kami kumounter.

Dyosa Comment: Haven't used this ever!

Push
Meaning: to press an aggressive attack
Use in Sentence:Patay lahat ng heroes! PUUUUUUSSSSHHH!!!
Etymology: It was always been used ever since we played.
Dyosa Comment: A general DotA gameplay Jargon

Beyond the friendship and camaraderie that we had with DotA, we genuinely care for each other. We fought the struggles of our Chemical Engineering journey together. We studied together. Shared information with each other. Although some of us became casualties of some subjects, but still, we pushed for the gold which was passing the subjects together.

I am very much proud to exclaim that no one in our ranks of brothers-in-arms ever resorted to cheating in exams. We may have failed our subjects but we never, and I emphasize it more, NEVER cheated. It was a do or die system for us. You'll pass if you're meant to pass. Always giving 100% of our capacity to exams.

I consider myself lucky to be part of this group of misfits. We may not be all great students like our cum laudes, but the end of the day, we are all CHEMICAL ENGINEERS regardless of our GWA.

Thank you boys. Thank you talaga. Alam nyo naman kung gno kayo kahalaga sakin.

After the first batch of high school students graduate from the Department of Education’s new Kindergarten to Grade 12 (K-12) program, some college programs will be shortened and first among these are engineering courses, Commission on Higher Education (CHED) chairperson Patricia Licuanan said Friday.

Licuanan said the CHED engineering technical panel "has decided" to cut short the five-year engineering programs to four years, but "some of the science technical committees, however, have categorically said their programs cannot be shortened."

According to CHED estimates, some 322,000 students will enroll in engineering and technology programs for school year 2012-2013.

The country's colleges and universities produce about 48,000 to 49,000 engineering graduates yearly, CHED data show.

Last month, DepEd Secretary Armin Luistro revealed in a meeting of the Philippine Business for Education that college courses will become shorter because of the curricular changes in basic education under the K-12 program.

Licuanan clarified though that the proposal to shorten college courses did not come from CHED, but from its technical panels of experts who come from stakeholder sectors.

She said the changes in college degree courses "will be the product of long and intense discussions and that comments made or ideas floated during the discussions must not be interpreted as definite plans."

She confirmed previous reports that the technical panel on general education (GE) "has initially proposed a shorter GE curriculum as some GE courses will now be part of Grades 11 and 12." —VS, GMA News

hmmmp... I don't quite agree that Engineering should be shortened to 4 years. Most especially my field of Engineering of Chemical Engineering. I understand that some of the General Education subjects are to be taught in the latter parts of the K-12 classes, but I think that dropping a year should not be done. I think it would be better to make the 5th year as an expertise year. There are numerous sub fields of chemical engineering that students can venture to. This can provide more edge to the Chemical Engineering Students since they specialize in a particular sub-field they can venture directly to the companies of the industry in their employment. Also, this can easily be a filter for those who wants to teach Chemical Engineering. They should be have an expertise of a particular field before venturing into the academe. Hence, increasing the competencies of the Faculty and the graduates alike.

Barium Carbonate is commercially important as a basis for the manufacture of other barium compounds. In its manufacture, BaS is 1st prepared by heating the natural sulphate barytes with Carbon. The BaS is extracted from this mass with water and the solution is treated with Sodium Carbonate to precipitate the barium. In the operation of such process it is found that the solution of barium sulphide formed contains also some calcium sulphide, originating from impurities in the barytes. The solution is treated with sodium carbonate, and the precipitated mass of calcium and barium Carbonates is filtered off.



It is found that 16.45 kg of dry precipitate are removed from each 100 kg of filtrate collected. The analysis of the precipitate is 9.9% CaCO₃ and 90.1% BaCO₃. The analysis of the filtrate is 6.85% Na₂S, 2.25% Na₂CO₃ and 90.9% H₂O. The sodium carbonate for precipitation was added in the form of anhydrous soda ash which contained CaCO₃ as an impurity.



Calculate:

a) % Excess Na₂CO₃

b) Composition of sulphide solution

c) Composition of dry soda ash

BaS CaS	+ Na2CO3	→	BaCO3 CaCO3	+ Na2S
	anhydrous with CaCO3 impurity		Precipitate 16.45 kg per 100 kg filtrate 9.9% CaCO3 90.1% BaCO3	filtrate 6.85% Na2S 2.25% Na2CO3 90.9% H2O

Basis: 100 kg filtrate

Since we have a basis of 100 kg filtrate we will have the following masses:

6.85 kg Na₂S → formed from rxn of BaS and CaS

2.25 kg Na₂CO₃ → unreacted Na₂CO₃

90.9 kg H₂O → water from Sulfide Solution

16.45 kg precipitate → combined mass of Barium and Calcium Carbonates



a) Find % excess Na₂CO₃:

m_reacted Na₂CO₃ = (6.85) [Na₂CO₃]/[Na₂S] = 11.56 kg

% excess	=	unreacted          Reacted + unreacted	x	100%
	=	2.25          11.56 + 2.25	x	100%
	=	19.47%

Solving for additional masses, Let:

x = mass of Na₂S formed from rxn of BaS

y = mass of CaCO₃ impurity from dry soda ash



m_BaCO3 = 16.45(0.901) = x [BaCO₃]/[Na₂S]


x = 5.86 kg



m_precipitate = mass of BaCO₃ formed + mass of CaCO₃ formed from rxn + mass of CaCO₃ from dry soda ash

16.45 = x [BaCO₃]/[Na₂S] + (6.85-x) [CaCO₃]/[Na₂S] + y


y = 0.3580 kg



b) composition of Sulfide Solution

m_BaS = 5.86 [BaS]/[Na₂S] = 12.72 kg = 12.17%

m_CaS = (6.85-5.86) [CaS]/[Na₂S] = 0.9138 kg = 0.87%

m_water = 90.9 kg = 86.96%

m_total Sulfide Solution = 104. 5338 kg



c) composition of dry soda ash

mass Na₂CO₃ = 11.56 kg = 97%

mass CaCO₃ = 0.3580 kg = 3%

mass total dry soda ash = 11.918 kg

Anu bang akala ng mga taga-UP? Mag-stand out sila kasi may sash silang suot? Well... Nagkakamali sila! Hindi nila ni-anticipate na may isang dyosang darating!



Anung say ng sash nila sa naglalagablab na Barong ko ha?! Wahahhahah!!! Sigurado ako, pag pinagtabi kami ng may sash ako ang mapapansin! wahahahah!!! I would like to thank Divisoria for my flaming hot Barong number! Winner!!!



Ngayon ko lang napagtanto... Ampogi pala pareho ng dalawang thesismates ko! whahahhaha! Syet! amplastic ko! whahhaha! Abangan ang Fantabulous post pag nag-upload na lahat ng pictures! Parasite ako eh! walang dalang sariling camera! whahahha!!!

Hindi pa din ako makaget-over sa sinabi saken ng dati kong prof sa mga dreaded subjects Unit Ops 3 & 4 at Reaction Kinetics na si Dean Laurito nung umatend ako ng Testimonial ng mga batchmates ko na pumasa na sa ChE Board.

"Iba na itsura mo ah. Mag-aartista kaba? baka sa susunod na makita ka namin nasa TV kana?

Ako? Moi? Mag-aartista? ASA NAMAN!!! Ni sa hinagap hindi ko naimagine na magiging artista ako. Siguro kasi ngayon lang nya nakita na mahilig ako magkulay ng buhok. Tapos tahimik lang ako sa klase nya. Sa totoo lang, medyo nakakaloka kasi sa classroom eh. Kaya ako tahimik kasi ayokong matawag. Wahahahah!

Anyway, kung makikita man ako sa TV, kung hindi cooking show, gusto ko sana Science and Technology Magazine show. Parang yung Tomorrow Today ng DWTV sa Germany. Kasi wala tayong ganun. Wala nang Sineskwela, moreover, pambata pa yung show na yun. Yung show na naiisip ko yung para ishowhsowcase yung mga researches na ginagawa ng mga FIlipino researchers. Kasi namamangha tayo sa mga researches ng ibang bansa pero hindi natin alam na may exceptional researches din naman ng ginagawa dito sa bansa natin. Tapos magfeature ng mga Brilliant minds both young and experienced alike. Tapos iexplain pano ginagawa ang mga certain consumer products (driven by my profession of being a Chemical Engineer siguro). Pwede din kasi syang gamiting alternative educational material. Tapos iexplain yung mga scientific procedures na applicable sa atin ngayon. Example yung DNA processing, pano ba sya nagagamit as Forensic Evidence, anu ba yung ginagawa dun sa DNA at nalalaman kung sino ang may-ari nun. Yung ganun. Siguro kaya hindi sya naaccept sa court, because there is no ample information given to those people para iopen yung mind nila sa mga ganung technology. Actually surprised ako na hindi masyadong accepted ng courts natin dito sa Pilipinas yung DNA processing kahit pa may law na about this. I mean cmon. Hindi ba sila nanunuod ng CSI? Goodness!

Gusto ko sana bago ako mawala sa mundong ito, magawa ko to. Kaya kelangan mag-workhard para makabili ng Technical Stuffs like cams, cables, etc. O kaya kung merong producers dyan! OPEN AKO FOR TALKS! CHOS! Shocks! Kaya to! I swear gagawin ko talaga to!
