MiCare Healthy Lifestyle fun run

The MiCare Healthy Lifestyle 5k fun run is a new addition to the annual running calendar. The run is unique in featuring a health screening tent. I stopped by pre-race and checked my numbers. Heart rate 58 bpm, blood pressure 130/72, fasting blood sugar 101. Those last three numbers are not good.

My son stayed with me longer and farther than ever before, running with me out to the Lidakida turn-around on the causeway. He finished hot on my heels at 31:06, thanks to his push I managed to just barely eke in under 30 minutes at 29:35. That is a PR for him, and a long time since I have seen a two as the leading digit.

After the run I re-checked my numbers. My blood pressure fell to 122/73, while my one banana blood sugar rose to 111. Pulse was 148 post-run. Thus my blood pressure fell, not rose. There is the possibility that pre-run I release adrenaline and thus lift my blood pressure in anticipation of the upcoming effort.

Reflection and Refraction

Laboratory eleven began with placing a one dollar coin on top of a towel and under a beaker filled with water. The top of the beaker was covered with a ceramic floor tile. I then asked the class to come up and determine what coin was under the bottom of the beaker.

Due to total internal reflection at the bottom, and refraction at the sides of the beaker, the coin is invisible.

Then I put the coin in an empty dish basin at a distance of four meters. No one could see the coin: the side of the dishpan blocked their view.


Then I filled the dishpan with water, and the students could now see the coin. This led to an explanation of apparent depth

Ariel Maylea and Alden set up to measure the depth of the penny tallest of the graduated cylinders.

 
Moses and Gorang determine the apparent depth of the penny in the tallest cylinder. This term again I lined up the cylinders from shortest to tallest on the middle table.


The board notes on the "index of reflection" portion of the laboratory. I opted to use the parallel terminology "index of refraction" and "index of reflection" to make clear the distinction between the two slopes.

Thatching

The class usually uses Nypa fruticans, called paremin Pohnpeian. In some terms the class used the traditional material for Pohnpeian thatching, Metroxylon amicarum, but this requires cutting down the tree to access the fronds. Nypa fruticans can be obtained non-destructively from the plant.
Maylanda Mikel demonstrates skill and speed in completing a section of thatch. In the above image she is removing the nohk.

There are two styles of Pohnpeian thatching, doakoahs en Ruk and doakoahs en Pohnpei or simply doakoahs. Doak means "to pierce" with a needle-like object. Oahs is the Pohnpeian name for Metroxylon amicarum.

The nohk is the back half of the midrib. Removing the nohk is necessary when using oahs due to the thick midrib. The oahs frondlet cracks and breaks unless this is done.

Christlynn and Joesen

In Chuuk pandanus is used for thatch, as well as coconut palm leaf. Coconut palm leaf has a reputation for a short life span across Micronesia.

On Pohnpei in the past the tip of a marlin (a bill fish) was used as a needle. Nowadays the sharpened end of a toothbrush with a hole in the end is a good needle, nails are also sometimes used. Nails with heads, however, do more damage to the frondlet due to their heads. In class we usually use carved pieces of bamboo.

Verginia and Claralyn

Expert craftsmanship and skill shows in the even spacing of stitches and the tightness of weave. String is not typically used to stitch the thatch together. Some use the outer skin of the main petiole on oahs. Others unravel rice sacks of woven plastic.

Joanie Lane

Frondlets are folded so as to create a one-third, two-thirds split in relation to the length of the frondlet. The base is one-third, the apical end is two-thirds.

Trisha

The minor rafters over which the frondlets are folded are made of either Phragmites karka(Chuuk: Woowo, niwo, Kosraen: loa, Pohnpeian: lirau) or Saccharum spontaneum (Kosraen: ac, Pohnpeian: ahlek). The minor rafters are called rahu in Pohnpeian. Today we used ;ahlek.

Gorang

Parem is too narrow to produce proper doakoahs en Pohnpei. Doakoahsen Pohnpei differs in being laid on a 45 degree diagonal. Note that traditionally Pohnpeian thatch was not covered by a net to protect the roof from wind damage.

Pauline

On the flat, outer island atolls in mid-ocean the wind is a more significant source of damage. On Pohnpei rain and subsequent thatch rot are apparently more problematic. Pohnpei thatch is not netted down. The thatch is designed to catch the wind and "fluff" slightly, aiding in drying of the thatch and slowing rot.
RinaRuth

The nohk is the back half of the midrib. Removing the nohk is necessary when using oahs due to the thick midrib. The oahs frondlet cracks and breaks unless this is done. This is not apparently strictly necessary with parem.

The nohk from oahs are then used to make a whisk broom. Teeth are used to crack the midrib and split the nohk. Removing the nohk from parem (nipa) is more difficult and produces smaller nohk than oahs.

Fall 2008 Cantina Albert demonstrated Kosraean thatching. Kosrae does not have oahs. Kosrae is presently thought to have only four species of palms. Coconut (Cocos nucifera), betel nut (Areca catechu), Ponapea ledermanianna (Kosrae: kitacr, Pohnpei: kedei) , and Nypa fruticans

Fall 2009 Cantina Albert of Kosrae returned to demonstrate Kosraean thatching. During this session she secured the minor rafter with her foot.



Linguistic note: dok is "pierce" while oahs refers to Metroxylon amicarum. The combining of the words is what is known in linguistics as verb noun incorporation or incorporated objects. When the word is by itself, it is dok (intransitive), which means to pierce or to stab. The transitive form of it on the other hand is doakoa. The use of /oa/ is sometimes /o/, depending on the following vowel or consonant sounds. For instance, doakoahs, to pierce oahs, dokpwihk, literally to stab a pig (to pig-slaughter), dokomwomw, to spearfish,etc. [Source: Robert Andreas]

Lubuntu 11.04 to 11.10 dist upgrade reversion to Unity

Where a computer had been running Ubuntu 11.04 and the Unity desktop, and said computer was changed over to the Lubuntu 11.04 desktop using the Ubuntu Software Center, the computer reverts to Ubuntu with the Unity desktop on distribution upgrade to Ubuntu 11.10.

Worse, the automatic log in is reset to user name and password required, in other words, the autologin is disabled in default.conf and dgod is re-enabled, even if one clicks on "keep" configuration file intact.

Getting back to an automatic log in Lubuntu 11.10 desktop is all but impossible - only loading Lubuntu 11.10 from a CD - a full reinstall, works to get back to Lubuntu.

There is a partial work-around, but it leaves in place the splash screen. The issue appears to be the switch to the lightDM desktop manager in 11.10, it usurps the lxdm desktop manager.

The work around is described below.

Upon restart after upgrade one will find oneself in the Ubuntu 11.10 Unity desktop, a desktop that remains infinitely confusing for my students. Log out from the desk top and return to the log in splash screen.


Click on the "gear" wheel in the log in dialog. Change the desktop from Ubuntu to Lubuntu. Log in using the password.


Once logged in, choose Users and Groups.


Note the Password: Asked on login. Click on change.


At the bottom of the pop-up dialog box choose Don't ask for password on login.


Enter password again. Click OK and Close out the dialog boxes. Restart.


At this screen press Enter or click on Login to boot to the Lubuntu desktop. Not automatic, but no password needed.

Automatic login is not possible. Editing the default.conf file results in an automatic login to the Unity desktop, even if the desktop choice had been Lubuntu.

Note that none of the above happens unless the computer has the gdm and ran Unity under 11.04. Lubuntu 11.04 boxes built from the CD retain their automatic login capabilities and remain in the Lubuntu desktop on upgrade.

Gall stone

Checked in for abdominal discomfort, ultrasound reveals a gall stone.

Juggling children was the nature of the week. Tuesday and the three were up at the college.


A dear friend whomped up the most wonderful all organic spaghetti with salad and whole wheat muffins for the children one evening.


A very happy customer!

A couple nights later a noise in a cabinet at Genesis...


... and this is how babies arrive! Not from the stork but by popping out of cabinets in the surgical ward.


No fear of either the dark nor enclosed spaces.

In on a Sunday, removed on a Tuesday, discharged on Friday. The cause of the discomfort: a gall stone of some size.

Assessing cloud drawings

Once again I turned to a team of professional crayon drawing evaluators to assist in evaluating the cloud drawings done in physical science laboratory eight. As they have in the past, the two of them discussed and argued the arrangement of the images. This term they worked using the descriptors in the marking rubric.


From left to right the columns mark accuracy of the drawing with respect to shapes, forms, colors, and light source. From top to bottom marks composition, consistency of drawing style, and apparent effort made by the artist.
