Since we’ve been looking at air conditioning lately…

Watts = BTU / EER
Amps = Watts / Volts
Volts = Watts / Amps

The Voltage will normally be 230 if the Watts are higher than 1000 (generally units higher than 10000 BTU), otherwise 110. For amperage calculations, the rated value seems to use either 100 or 110 Volts for 110 Volt units and 225 Volts for 230 Volt units.

To calculate the cost of running, calculate the total kW h and multiply by the rate.
For example:

6 hours/day * 30 days * 950 Watts = 171,000 W h = 171 kW h
171 kW h * 0.10 $/kW h = $17.10

(BTU = British Thermal Units)
(EER = Energy Efficiency Ratio)

… Trust me on this — you really do not need to read through those academic research papers. Here is a summary: The ‘scholarly consensus’ is that children and parental happiness just do not go together. According to the data, parents are less happy than non-parents, parents of infants and toddlers are especially not happy, single parents are less happy than married parents, and mothers are less happy than fathers. Except, that is, when it comes to single fathers, who are the most unhappy of all…

Christians must see children as gifts from God, not as projects. We should see marriage and parenthood as a stewardship and privilege, not as a mere lifestyle choice. We must resist the cultural seductions and raise children in the nurture and admonition of the Lord, and understand family life as a crucible for holiness, not an experiment in happiness…

And when it comes to happiness, we must aim for something higher. Christians are called to joy and satisfaction in Christ, and to find joy in the duties and privileges of this earthly life. Every parent will know moments of honest unhappiness, but the Christian parent settles for nothing less than joy…

I know it’s been a month now, but it seems I hadn’t posted the preview trailer yet:

Also note that the official website has been up for a while as well. It includes a flash map game that they are adding to as time goes on.

The central dogma of molecular biology, as proposed in 1970 by Francis Crick and James Watson, holds that genetic information is transferred from DNA to functional proteins by way of messenger RNA (mRNA). This suggests that mRNA has but a single role, that being to encode for proteins.

Now, a cancer genetics team at Beth Israel Deaconess Medical Center (BIDMC) suggests there is much more to RNA than meets the eye.

In a study appearing in the June 24, 2010 issue of Nature, the authors describe a new regulatory role for RNA — independent of their protein-coding function – that relies on their ability to communicate with one another. Of potentially even greater significance, because this new function also holds true for thousands of noncoding RNAs, the discovery dramatically increases the known pool of functional genetic information…

“Because this new function does not depend on the blueprint that RNAs harbor in their protein-encoding nucleotide sequence, the discovery additionally holds true for the thousands of noncoding RNA molecules in the cell,” explains senior author Pier Paolo Pandolfi, MD, PhD, Director of Research at the BIDMC Cancer Center and George C. Reisman Professor of Medicine at Harvard Medical School.”This means that not only have we discovered a new language for mRNA, but we have also translated the previously unknown language of up to 17,000 pseudogenes and at least 10,000 long non-coding (lnc) RNAs. Consequently, we now know the function of an estimated 30,000 new entities, offering a novel dimension by which cellular and tumor biology can be regulated, and effectively doubling the size of the functional genome.”…

I’ve been enjoying the World Cup so far. The next game for the Netherlands is Friday against Brazil. It should be fun to watch – even though Brazil are the favorites.

“Hup Holland hup
Laat de leeuw niet in z’n hempie staan
Hup Holland hup
Trek het beessie geen pantoffels aan

Hup Holland hup
Laat je uit ‘t veld niet slaan
Want de leeuw op voetbalschoenen
Durft de hele wereld aan”

A fairly quick update of the last couple of weeks.

On Saturday, William and Niamh finished off their swimming lessons for the season. On her third try Niamh finally passed her course, and William passed his as well. Niamh will start her next lessons in the summer, but William will be playing baseball instead.

Also on Saturday, Alana went to a community garage sale and picked up a bike for Niamh. We have a few kids bikes, but Niamh is still too small for them, so Alana found a 12-inch rimmed bike for her to learn on. So after brining the kids back from swimming lessons, I installed the training wheels on Niamh’s new bike and helped her learn how to ride.

Well, the new baseball season has arrived, so I’ll do a quick summary of the first few games. I’m on my brother Doug’s team this year, and it looks to be a fun year, despite the start. We lost our first two games, first against Matt’s team by two runs, then by another team by about 8 runs, or so. Last night we played our third game and earned our first victory by a score of 31-10. Hitting-wise, I’ve started out okay, with nine singles, two doubles, and one triple in 17 at bats, so it’s a .706 average and .941 slugging pct. Fielding has been okay, but could be better. In the first game I played second base for one inning and all I can say is that I’m back in the outfield now. William will be playing T-ball this year again, but that won’t start for a few weeks. It will be fun to watch him again.

Alana and I have both been under the weather a bit for the past couple of weeks or so. Headaches, and sinus infections seem to be generally what is bothering us. I have been feeling a bit better the past two days, though, so I’m thankful for that. William missed two days of school last week due to a flu. He was throwing up quite a bit, so Alana had him on Thursday and I worked from home on Friday so I could take my turn. Niamh started complaining of a headache in the middle of the service on Sunday morning, and she had a high fever, so Alana took her home and she stayed in bed all day. She decided to throw up as well, once on me (which is fairly easy to clean up at least). Yesterday she wasn’t feeling to well when she woke up, but seemed to get better quickly after that. She seems to be doing pretty well right now.

So there’s a little update on some stuff. I haven’t had much time to write much else, but other than that, the kids are finishing their swimming lessons up this week, and we finally got off dialup (we cancelled our satellite TV service as well, since we don’t watch much anyway, and would prefer watching what we can better screen on DVD anyway).
