Question:
I am in the process of losing weight and I have a
question about fruit drinks. I just read an article on this site that says it is better to
drink fruit juice instead of a carbonated diet drink. How do I know which fruit juice is
really giving me the nutrients I need? I love fruit juices, however, they contain so many
calories and carbohydrates I almost feel guilty drinking them. So, I am stuck between a
rock and hard place, so to speak. If I drink fruit juices, I consume almost 220 calories,
and if I drink a Diet Pepsi, then I consume almost no calories, but possibly then become
bloated and eat more calories anyway! Ugh! I guess if I knew I was getting more nutrients
out of what I was drinking I would feel better about the calories I am consuming. Could
you please help me out?
Answer:
The bottom line is that while fruit juices contain
essential nutrients, they are high in calories. You are better off to drink water to
quench thirst and eat a piece of whole fruit to satisfy hunger or sweet cravings. For
losing weight, whole fruits give more bang for the buck. As for carbonated drinks, while
they have no nutritional benefits, they can help stave off hunger and/or sweet
cravings. The HFT Staff

NGC 4013:
A Galaxy on the Edge
NASA's Hubble Space Telescope has snapped this remarkable
view of a perfectly "edge-on" galaxy, NGC 4013. This new Hubble picture reveals
with exquisite detail huge clouds of dust and gas extending along, as well as far above,
the galaxy's main disk.
NGC 4013 is a spiral galaxy, similar
to our own Milky Way, lying some 55 million light-years from Earth in the direction of the
constellation Ursa Major. Viewed pole-on, it would look like a nearly circular pinwheel,
but NGC 4013 happens to be seen edge-on from our vantage point. Even at 55 million
light-years, the galaxy is larger than Hubble's field of view, and the image shows only a
little more than half of the object, albeit with unprecedented detail.
Dark clouds of interstellar dust stand
out in the picture because they absorb the light of background stars. Most of the clouds
lie in the plane of the galaxy, forming the dark band, about 500 light-years thick, that
appears to cut the galaxy in two from upper right to lower left. A similar effect can be
seen in our own sky. If one views the Milky Way by going well away from city lights, dust
clouds in the disk of our own galaxy appear to split the glowing band of the Milky Way in
two.
When light passes through a volume
containing small particles (for example, molecules in the Earth's atmosphere, or
interstellar dust particles in galaxies), it becomes fainter and redder. By studying the
color and the amount of light absorbed by these distant clouds in NGC 4013, astronomers
can estimate the amount of matter in them. Individual clouds contain as much as one
million times the amount of mass in our Sun.
Dark interstellar clouds are believed
to be where new stars are formed. Later, when the dust disperses, the young stars become
visible as clusters of blue stars. NGC 4013 shows several examples of these stellar
kindergartens near the center of the image, lying in front of the dark band along the
galaxy's equator. The extremely bright star near the upper left corner, however, is merely
a nearby foreground star belonging to our own Milky Way, which happens to lie in the line
of sight to NGC 4013.
This Hubble Heritage picture was
constructed from Hubble images taken in January 2000 by Dr. J. Christopher Howk (Johns
Hopkins University) and Dr. Blair D. Savage (University of Wisconsin-Madison). Images
taken through three different filters have been combined into a color composite, covering
the region of the nucleus of the galaxy (behind the bright foreground star at the upper
left), and extending along one edge of the galaxy to the lower right.

TIPS Sebelum
mendisain ulang kebun Anda
1. Lihatlah melalui jendela rumah Anda, dan perhatikan apa yang Anda lihat.
Apakah pemandangan dari ruang tamu, dapur dan dari ruang-ruang lainnya sama dengan apa
yang Anda lihat sekarang? Bila tidak, mungkinkah pemandangan ini dapat diubah atau
didesain ulang dengan menanam atau membangun sesuatu untuk menonjolkan keindahan atau
menutupi kekurangan dari area di luar rumah kita?
2. Duduklah bersama-sama anggota keluarga Anda
dan diskusikan apa yang baik and buruk tentang rumah serta tanah di pekarangan, dan
daftarlah apa-apa yang ingin mereka ubah
3. Perhatikan dengan cermat rumah dan
pekarangan rumah orang lain ketika Anda berjalan-jalan. Bisa juga Anda menyempatkan diri
dengan mengikuti tour sebuah organisasi klub berkebun, masyarakat hortikultura dan
organisasi amal lainnya
4. Ukurlah dan catat dimensi rumah Anda, termasuk
lokasi jendela, pintu masuk, posisi pohon-pohon besar, jalan raya, trotoar, dinding, garis
pembatas dengan tanah tetangga, dan lain-lainnya. Dengan menggunakan ukuran ini, buatlah
sket pandangan mata burung rumah dan pekarangan Anda ini
5. Mulailah membuat sket perubahan lansekap
kebun Anda pada kertas kalkir. Jangan kecewa bila Anda mendapatkan hasil yang kurang
memuaskan. Mulailah lagi, dan hasil
sketsa Anda sebelumnya jangan dibuang - siapa tahu Anda akan membutuhkannya kemudianKlik untuk info lengkap |
Elementary rules of
"computer hygiene":
- In BIOS toggle off the ability of the computer to be loaded
from disk A (only C);
- The antivirus scanner (monitor) should be loaded
automatically together with the operating system;
- When using somebody else's floppy discs or other removable
carriers apply antivirus control;
- Don't be lazy and when installing any (!!!) program from
CD-ROM, antivirus ones included, check out the disc for viruses;
- When receiving E-mail from the sources unknown to you,
especially with the availability of attachments, delete the letters even without looking
them through. Otherwise you take a risk to lose either control of the system or your
information.

| .Are we doing enough to save the earth?
How much would it cost to rebuild our entire civilization? Is this the ecological deficit
we are leaving for our children? The
quantities of Greenhouse Gases, such as Carbon Dioxide, Methane and CFCs, which have
already been produced by industrial societies is at a level which has triggered the
comings and goings of Earth's Ice Ages during the last million years. Recent discoveries
in the geological record reveal that transitions into and out of ice ages are marked by
cataclysmic changes in climate conditions and sea levels. We can not depend upon gradual
climate changes or sea level variations to which we can accomodate ourselves during a
Greenhouse Century. 120,000 years ago, conditions were very similar to what they are now,
when the last ice age began. Earth suddenly lurched into what scientists refer to as the
Madhouse Century, the transition period into the Ice Age. During the Madhouse Century sea
levels abruptly rose 20 feet from where they are now, and then plummeted fifty feet, all
in one hundred years. The magnitude of the climate
crisis requires nothing less than an all-out emergency effort to convert western economies
away from fossil fuel dependence. To build a truly sustainable economy and eliminate human
interference with global climate cycles, the Climate Action Now will present a wide range
of resource access for activists, educators and journalists, and opportunities for
personal involvement in what must become one of the greatest mobilization efforts in human
history.
