Daylight saving time tonight

Here we go again. At 02:00 tonight, we turn the clocks an hour (to 03:00) due to the daylight saving. Since 2 is about the time I go to bed on weekends, it will feel like I’m going to bed really late tonight. Damn it. Oh well, since I have rehearsal on Monday 12:00 I’m at least happy I accidentally saw the news about it on Corren.se (Swedish news site).

The Islander's cover

So, Nightwish has finally released the cover to their next single – The Islander, due to release on May 21, as I mentioned in another blog entry. A nice cover (as always from Nightwish), a beautiful song and probably a great music video (to be released on April 14). I honestly don’t think they´ll ever let me down.

The Islander

Simone Simons' health

Goddamnit… From Epica’s offical website:

After having had a couple of weeks of rest we were very much hoping that Simone’s situation would have improved already. Unfortunately the last MRSA test was still positive and also the infections still haven’t stopped completely. We have the feeling Simone’s health is improving but unfortunately not enough yet. We cannot risk the health of Simone and therefore, with pain in our hearts, we cannot come to Mexico and Colombia again. Also two of our three shows in the UK are cancelled for this reason. It’s still impossible for Simone to make long trips. As you can imagine we feel really bad about this, especially since our Mexican/Colombian tour was already postponed once before, but we also hope you understand and respect our decision on this. You all have our word that we will come back as soon as possible to make up for all this. Unfortunately at this moment we just can’t tell when this will be but we hope before the end of this year.

Essays

If you wonder why I just uploaded some (What was it? Seven?) essays here, It was when I realised how many visitors some has given me. Oh my god, some people are really lazy and try to use others school work. Well, it’s not my fault when they get busted or starts reading at the University and suddenly has to do it all by themselves… and hey, there’s the little thing called Google AdSense…

2. The Light Bulb and the Plates

 

2.1 Planning

2.1.1 Description of Lab

The second lab on thermal energy was to understand how fast light emitted thermal energy to objects around – in this case three plates of different colour.

                      The light bulb is to be placed in the middle of the three plates – one silvery, one black and one white – from the same length (10 centimeter). On the back of every plate, we will have taped a thermometer. We will then turn the light bulb on, and every minute (starting when we have just turned the light bulb on, recording this as after 0 minutes) check the temperature and note this down so we later can analyse the results.

                      As soon as we are convinced that the plates have reached their top temperature, we will turn the light bulb off and analyse the drop of temperature for a while.

 

2.1.2 Equipment and Materials Needed for Lab

·           Nearby electricity for the light bulb

·           Light bulb

·           Timer

·           Holder for the three plates

·           Three thermometers (and tape)

·           Pen and paper for noting results etcetera

 

2.1.3 Diagram of the Equipment’s Set Up

See page 3.

 

2.1.4 Hypothesis

I believe that the three will begin on about the same temperature (experience tells me that there’s always an error making one start on one degree higher or lower because of for example miscalculation, bad measuring on the length between the light bulb and the plates, etcetera), and have their temperatures increased steadily. I think that the black plate’s temperature will increase faster, as black is a colour that easier attracts thermal energy. As silver reflects thermal energy more, I think the silvery plate will not be as affected. The white will probably stand somewhere in the middle, as I’m not familiar with anything special about that colour (associated with thermal energy).

Of course we have to consider that everything works totally correct for having these results. The main impact on the results is probably bad timing – if someone is late checking the temperature or similar. As explained earlier, there’s always something that goes wrong. It can also be that we measure wrongly and that one of the plates is to far away from the light bulb, resulting in temperature increasing slower. There’s not really a way to avoid these errors but to be extra careful – check everything twice.

 

2.2 Performance & Conclusion

2.2.1 Results

See page 4 and 5.

 

2.2.2 Conclusions

All three of the plates turned out quite similar (as expected). At first, both the silvery and the black started at 21 degrees Celsius and the white started on 22 (probably because of an error, see section 2.1.4 for more information). After four minutes, all three of them had somehow gotten to 24 degrees. After six minutes, we turned off the light bulb, so a few minutes after that the temperature started to decrease. All of them were on different numbers when we stopped the lab, after five minutes; silver on 22, black on 21 and white on 23.

                      I had expected the silvery plate to be much less affected, but still it actually increased and decreased much quicker than the white, which I had expected more so of. Though, as expected, this was the one who didn’t warm up as much as the others (as I had expected),

                      The black plate was the most reactive to the thermal energy, quickly raising in temperature and reaching the highest in the middle – 25 – as well as the lowest in the end – 21. This was expected in my hypothesis, as I already knew how attracting black is. In the end (minute 12-14) it jumped from 21 to 22 degrees, and then back to 21. This is for an unknown reason that I cannot understand at all. Probably it was just a miscalculation, or minor changes in wind, room temperature or similar.

                      The white plate truly was the most boring one. As already pointed out, it started on 22 degrees for an unknown reason. It then was the only one to only jump one degree for the first minute. It stayed on 23 for one minute, and then changed into 24 to stay there for seven minutes, then turning back into 23 for the rest of the time. White took the role that I thought silver would have, being barely effected by the thermal energy at all – only taking skips of one degree at the time, without having time to cool down to less than 23 degrees before we finished the lab.

1. Water and Insulation

1.1. Planning

1.1.1 Description of Lab

What change of temperature drop will there be if the object is insulated differently? This question was to be answered as the lab was made. A bottle of water is warmed up with a bunsen burner, and the water is then poured into two different tubes, one normal glass tube and one insulated with styrofoam. The both tubes’ temperatures will then be checked with continuality every sixty seconds for ten minutes. The numbers will then be listed in a table steadily showing the way down for both temperatures.

1.1.2 Equipment and Materials Needed for Lab

· Bunsen burner to boil the water

· Glass bottle to boil water in

· Holder for glass bottle

· Two equivalent glass tubes

· Holder for the two tubes

· Two high temperature thermometers

· Tong for the glass tubes

· Pen and paper for noting results etcetera

1.1.3 Diagram of the Equipment’s Set Up

The equipment for the lab is to be set up as follows on the diagram shown below. The bunsen burner is placed under the holder for the glass bottle filled with water. As the water is boiling, the next step is then to pour the liquid into to tubes, both placed upon each holder, one tube being insulated. This is marked as ”2” on the diagram.

Lap report set up

1.1.4 Hypothesis

My prediction of the results for this lab would be that the both temperatures will fall pretty steady, with about five degrees Celsius per minute, but that the non-insulated tube’s temperature will fall with a couple of more degrees than the insulated. The insulated easier keeps the temperature as Styrofoam is an object that is worse leading energy than air, that revolvs around the other tube. As energy is equal to warmth, it means that air easier brings away the heat, and therefore that the tube that’s not insulated will have a temperature which drops in degrees faster. Summary of my hypothesis, then: the both tubes will start at the same temperature (about 90 degrees Celsius, I believe, as it was boiling only seconds before) at 0 minutes. As the time goes, the temperature of both will drop steadily, but as the non-insulated tube’s drops with about five degrees, the insulated’s drops with about three degrees on the same time, because of the Styrofoam’s worse energy leading capacity.

1.2. Performance & Conclusion

1.2.1 Results

See the attachment.

1.2.2 Conclusions

The black tube had a temperature which steadily dropped from beginning at 0 degrees Celsius to have reached 45 degrees after ten minutes, which was the highest drop. As for the others, the temperature dropped heavily on the first step, as the water temperature adapted to the sudden change of temperature (when the heating thermal energy of the Bunsen burner was taken away), and in this case the drop was five degrees, which also was a record for the lab. Another heavy drop was recorded between the second and third minute, six degrees, but after that the drop was steady with one or two degrees per minute.

Together with the black tube, the shiny tube was the only to have a temperature starting on 64 degrees (that the others weren’t was probably a miscounting, or that the other tubes were filled with water too much later). Here as well as for the black tube, heavily drops of temperature were made in the beginning, even though the first minute’s drop isn’t as large as the black’s first, being three instead of five degrees. Something interesting later developed as the temperature stayed the same (56 degrees) for three minutes (4 – 6), till it dropped two degrees at once. After this, the temperature dropped by one degree per minute till it was on 51 degrees after ten minutes.

The insulation clearly helped for keeping the temperature. It is much harder for the thermal energy to leave the tube when it is trapped inside Styrofoam, since it is a bad conductor of it. The temperature started at 58 degrees (see last paragraph) and barely developed anything, staying on the very same degree for two or three minutes in a row. Ending on 54 degrees, it only changes four degrees, while for example the black tube change 20.

The copper tube’s temperature drop was quite steady, starting at 59 and after ten minutes being on 48 degrees. It varied a lot from dropping one and two degrees, once staying on the same temperature for two minutes. I would have expected a bigger jump for the first minute, otherwise it is as I expected.

It all appeared to be quite a lot as I expected it to, even though I thought that there would be larger temperature; what I expected was about five degrees per minute turned out to be a median of one or two. I hadn’t thought much of difference between the three (excepting the insulated one) and I was kind of right about this since this fourth tube clearly stood out from the rest. I have afterwards realised that the black colour much easier conduct thermal energy than the shiny and the copper.

Hemkunskap: Bostadskunskap

Bostadskunskap

Mitt första boende

I framtiden är mitt mål att arbeta som läkare, tills vidare har jag inte tänkt mer än lite grann på specialisering eller att arbeta kommunalt eller privat, därför är det svårt att avgöra min lön. Som AT-läkare är medianlönen 25 000 per månad och den lägsta möjliga är 22 500. Som ST-läkare är medianlönen högre, och den ligger på 34 700 i månaden. Specialistläkare har en lön på runt 45 850, och överläkare 54 600. Utöver detta tillkommer också ersättningslön för jourer. Jag kan tills vidare planera lönen som 22 500, då detta i standard sett är en läkares första lön.

1) Svara skriftligt på en annons

Hej!

Skriver angående mitt intresse för er lägenhet på Luftvärnsgatan 48 i Västra Berga, med hyran på 1936 kronor i månaden.

Jag har precis kommit hem till Sverige efter min läkarutbildning i Danmark, och ska nu påbörja min allmänna tjänstgöring som AT-läkare på US, Universitetssjukhuset i Linköping. Jag har en stadig lön på 22 500, så det finns ingen risk att jag kommer misslyckas med hyrabetalningen. Utöver mitt arbete är jag en kreativ, estetisk person som tycker om teckning och musik, och jag spelar gitarr samt piano. Innan jag påbörjade min utbildning i Danmark var jag också ideell ungdomsledare för en scoutkår i Tallboda.

Som referenser kan jag ange:

· Karl Michael Eriksson, 013 – 22 84 85 (min arbetsgivare på US)

· Ulf Johansson, 013 – 24 44 62 (ordförande på scoutkåren där jag ideellt medverkade)

2) Vilka rättigheter och skyldigheter har du som hyresgäst?

Det är vissa saker som du som hyresgäst alltid måste komma ihåg. Om dessa skyldigheter inte följs finns en risk att du blir uppsagd från lägenheten. Dessa skyldigheter inkluderar att betala hyran i tid, att inte störa grannar genom exempelvis hög musik eller störande husdjur, att inte hyra ut lägenheten i andra hand om du inte fått lov till det, och så den självklara skyldigheten att du inte får förstöra bostaden.

Det du får göra med din bostad är att måla om, tapetsera och lägga heltäckningsmatta. För större reparationer än så måste du be om tillstånd först. Om lägenheten inte blivit renoverad på över tio år kan du begära att få den målad och tapetserad. Även om den har felaktigheter såsom läckande kranar med mera har du som rättighet att få det fixat.

3) Vad bör man tänka på när man ska planera och inreda en bostad?

Inför inredningen av ens första bostad är det bra att kolla upp många olika möbler. Impulsköp inte, utan jämför pris affärer emellan. Se också efter för systemet ”Möbelfakta”, som kontrollerar möbler efter EU-standarderna, så att möbeln är väl tålig, säker mot brand och fungerande. Om du har dålig ekonomi är det även en bra idé att handla möbler begagnat, antingen genom annonser i tidningen, på Internet, på auktioner eller i affärer som säljer begagnat.

Hur man ska planera kan utöver detta delas in i tre större punkter; användning och funktion, personlig smak och framtid.

Användning och funktion

Viktigt med möbler är att de ska vara enkla att använda och tåliga, och att man ska kunna rengöra dem. När man ser på den här punkten tänker man på olika slags material, som olika sorters trä på en stol eller olika tyg på en soffa. Stolen som du tycker är snygg kanske har jättedåligt trä som spricker efter ett år. Och soffans tyg kanske inte går att tvätta av, och du får lida med en smutsig soffa.

Personlig smak

Självklart vill alla avgöra vad de tycker är snyggt eller bekvämt för just dem innan de köper det. Det är ju just den personen som köper det som ska använda det. Alla kanske inte behöver en dator, andra som arbetar på ämnet kanske behöver både dator, skrivare, scanner och Gud vet vad mer.

Framtiden

En ny bostad ska för det mesta användas inte bara det närmsta halvåret, utan under en längre period. Därför är det viktigt att anpassa möblemanget efter framtiden, och göra det möjligt att köpa in mer. Därför behöver man kanske inte köpa mer än det man behöver den närmsta tiden?

4) På lägenhetsskissen ska du rita in dina möbler skalenligt (1:50)

För skissen, se bilagan. Det som inte finns inplacerat på skissen utan bara finns med i listan här är föremål som finns i hyllor och liknande.

Jag började med att inhandla måsten, och jobbade mig sedan mot dyrare saker, som soffa, säng och elektronik (TV, dator, skrivare mm). Jag avstod från att köpa extra saker utöver detta, dels eftersom lägenheten skulle bli alldeles för trång och dels för att det är smartare att vänta och köpa det när man finner behov av det senare i livet.
