Homemade Water Filter Materials
- (filter material) Filter material is a porous type backfill, usually used surrounding perforated pipe underdrains, which intercepts water flow and directs it into the pipe.
- Made in the home; Made by oneself; In a simple style as if made at home
- made or produced in the home or by yourself; "homemade bread"
- homeMADE is an Australian reality television series that airs on the Nine Network. It premiered on 10 May 2009, and episodes air twice weekly on Tuesdays at 7:30pm and again at 9:30pm. The series is presented by David Heimann, who also acts as a mentor to the contestants.
- Made at home, rather than in a store or factory
- body of water: the part of the earth's surface covered with water (such as a river or lake or ocean); "they invaded our territorial waters"; "they were sitting by the water's edge"
- A colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms
- supply with water, as with channels or ditches or streams; "Water the fields"
- This as supplied to houses or commercial establishments through pipes and taps
- One of the four elements in ancient and medieval philosophy and in astrology (considered essential to the nature of the signs Cancer, Scorpio, and Pisces)
- binary compound that occurs at room temperature as a clear colorless odorless tasteless liquid; freezes into ice below 0 degrees centigrade and boils above 100 degrees centigrade; widely used as a solvent
Materials for Optical Limiting II: Volume 479 (MRS Proceedings)
The proliferation of lasers and systems employing lasers has brought with it the potential for adverse effects from these bright, coherent light sources. This includes the possibility of damage from pulsed lasers, as well as temporary blinding by continuous-waver lasers. With nearly every wavelength possible being emitted by these sources, there exists a need to develop optical limiters and tunable filters which can suppress undesired radiation of any wavelength. This book addresses a number of materials and devices which have the potential for meeting the challenge. The proceedings is divided into five parts. Parts I and II cover research in organic and inorganic materials primarily based on nonlinear absorption or phase transitions for optical limiting of pulsed lasers. Part III includes photo-refractive materials and liquid crystals which find primary applications in dynamic filters. Part IV covers various aspects of device and material characterization, including nonlinear beam propagation effects. Theoretical modelling of materials properties is the subject of Part V.

Specialty coffee shops in Berlin are turning their focus to extraction
While most cafes in Berlin are known for their espresso drinks, several have opened over the past few years with a focus on extraction methods, sharing a focus on high-quality beans and multiple extraction methods. Cafe CK (pronounced tsay-kah) is one such cafe.
Marienburger Stra?e 49, Berlin
TEL: 030 6883 4905
1. Right by the entrance, there's an espresso machine on the counter, and an easy-to-understand picture of three types of extraction tools.
2. An illustration is used to explain the differences between each variety of espresso drink.
3. The coffee beans used for single-origin coffees are on display on the counter, and also for sale.
4. A large window makes the cafe inviting and memorable.
5. Seating in front of the counter. The walls serve as a gallery, switched out every few months.
Cafe CK has provided specialty coffee since April 2009, when it opened in the Prenzlauer Berg neighborhood of Berlin. Their main menu consists of cappuccinos, latte macchiatos, and other espresso drinks that serve as standard cafe fare, but they also offer single-origin coffee extracted in many ways: by paper filter, AeroPress, and French press. They buy both their espresso and single-origin beans from a local roaster in Berlin. They have three or four types of single-origin beans from sources such as Kenya and Costa Rica, switched annually depending on crop.
The single-origin coffees are served according to the bean type and extraction method of the customer's choosing, with the three extraction tools lined up on the counter. Many customers choose only the bean type at first, with a paper filter used for extraction unless otherwise specified, but many of the regulars appreciate the different flavors of each extraction type. Says co-owner Corey Andreen, "it's a matter of taste, but a big factor in the difference in flavor by is the material from which the extracting filter is made. Among the three, the paper filter of the AeroPress gives the lightest and most refreshing taste, the metal filter of the French press allows oils to permeate, giving the coffee a more noticeable body, while the paper filter is somewhere in between."
Coffee extracted by filter is the least ordered, perhaps because such filters are usually associated in Germany with home brewing. Even so, Cafe CK is aiming to encourage new ways of enjoying coffee.
Seating in the back. The dim lighting makes for a laid-back atmosphere, and the exclusive use of sofas allows customers to relax with their coffee. The walls here too serve as a gallery to exhibit art.
Extraction products including the AeroPress and Hario V60 are displayed for sale on the shelves. Other products not used in the cafe are also for sale, including a Hario wood-neck and siphon.
Banana bread, brownies, and several other sweets are available, homemade from original recipes. A light menu is also offered, including breakfast and soup.
On the menu: espresso!

Three other types of extraction products
Single-origin coffee is extracted in three ways: paper filter (Hario V60), AeroPress, and French press. A slightly course grind is used for filtered coffee. The Hario V60 is popular among Berlin cafes that pride themselves on high-quality filtered coffee. Cafe CK has also started serving iced coffee from this summer using a Hario Fretta, which has been well-received, even among Germans not familiar with iced coffee.
Extraction by paper filter
1. Place a dampened paper filter in the Hario V60, and add 18g of a slightly course grind (Costa Rica in this case).
2. Pour in 300ml of 95°C water in several circular motions to soak the grind at first, and start to stir gently. The picture to the left was taken immediately after stirring.
3. Continue pouring several times.
4. After extraction, remove the dripper and serve the mug. The price differs according to the type of single-origin bean (from €3.00 to €4.30).
Extraction by AeroPress
1. Place the chamber on top of the plunger, and put 16g or ground beans into the chamber. Dampen the paper filter and screw on the cap.
2. Pour 265ml of 95°C water into the chamber. When halfway, stir gently and pour the rest. After pouring, place the cap securing the filter on top of the chamber and wait roughly 180 seconds.
3. Invert the chamber, place it on the server, and push the plunger down.
4. Finish by pouring it in the cup.

December 15th, 2010 'Day Trois Cent Quarante Neuf
Today was so good.
My AP Bio final was first thing in the morning. I have been studying for it for weeks now, and I might be so bold to say that I kind of enjoyed taking it, realizing that I knew all of the material on the test. After that, I went to lunch with my friends Nick and Emma. I climbed into the back of her car, which was littered with graded papers and textbooks, (as well as an empty rum bottle....) We sat in a very crowded Starbucks and munched casually.
We had to get back to the school very quickly to make the 4th period final. It was AP Photo, and all I had to do was present my Breadth, turn in my grading sheet, and clean the darkroom. She had Joe and Hans and I assigned to scrubbing the trays and rinsing them out. Well, really only those two. I had to go around and collect stray filters and clean the private darkrooms. As I walked by, Joe squirted me with the hose from the sink, Hans laughing with him. Naturally, I squealed and avoided them, but the water only became more prominent until we were having a legitimate water fight in the lit up dark room. It was wonderful.
Unfortunately, I can't say the same about my AP stats final. That went about as well as I expected it to, which was not very good at all. I hate that class. But for now, I am done.
After school, my mom picked me up (the family car is of necessity these days,) and we stopped by the post office right next to my house to pick up some Woodwick candles for Christmas presents. Parker was waiting inside my house when we got home, tinkering on the piano. We did the usual, lounged about, drank tea, talked, and rejoiced in the reality that the semester is over tomorrow.
(We also took some funny Christmas photos in front of the tree.)
Tomorrow is my Spanish final, and I'm bringing some homemade salsa to class. Parker helped me make it, as we chopped onions, tomatoes, cilantro, jalapenos, and mangos. The test bite had us in tears. It was that hot. So my mom suggested we add some raspberries to calm down the burn, which it did. *sigh* That was some damn hot salsa.
Now he is gone, and it is late, and I am more tired than I care to describe.
