Pemanasan Otak Ikan Marlin

Banyak jenis ikan besar bertahan hidup di laut dalam yang dingin dengan alat penghangat tubuh sendiri. Seperti ikan marlin, ikan layar, ikan pedang, atau kebanyakan ikan bertulang keras.
Ikan-ikan itu telah menjalani evolusi berabad-abad lamanya untuk membentuk organ pemanas yang dapat membantu berenang antara laut dalam yang dingin dan permukaan laut yang panas.
Ada massa jaringan seperti otot di dekat setiap mata ikan-ikan tersebut yang berfungsi sebagai termostat untuk menjaga otak tetap hangat, walau suhu air di luar tubuh sangatlah dingin.
Menghangatkan otak memiliki banyak kegunaannya (menurut para ilmuwan). Diantaranya, otak akan lebih cepat dalam menjalankan fungsinya. Menghangatkan otak memakan lebih sedikit energi daripada menghangatkan seluruh tubuh seperti yang terjadi pada kebanyakan hewan bertulan belakang (vertebrata).
Meskipun jaringan penghangat itu mirip oto, tetapi ia lebih menghasilkan panas daripada tenaga. Organ pemanas itu memperbaiki daya pandang ikan-ikan tersebut di laut dalam.

A North Island Brown Kiwi

A North Island Brown Kiwi

Apteryx mantelli or Apteryx australis


A North Island Brown Kiwi, is a one of flightless birds. At around the size of a domestic chicken, Females stand about 40 cm (16 inches) high and weigh about 2.8 kg, the males about 2.2 kg.The plumage is streaky red-brown and spiky.Brown Kiwis are found throughout the North Island, occurring near Northland, Coromandel, Eastern North Island, Aroha Island and Wanganui.

Kiwi are shy and usually nocturnal. Their mostly nocturnal habits may be a result of habitat intrusion by predators, including humans. In areas of New Zealand where introduced predators have been removed, such as sanctuaries, kiwi are often seen in daylight. Kiwi have a highly developed sense of smell, unusual in a bird, and are the only birds with nostrils at the end of their long bill.

Kiwi eat small invertebrates, seeds, grubs, and many varieties of worms. They also may eat fruit, small crayfish, eels and amphibians. Because their nostrils are located at the end of their long beaks, kiwi can locate insects and worms underground without actually seeing or feeling them.

Once bonded, a male and female kiwi tend to live their whole lives together as a monogamous couple. Kiwi's relationships may last for up to 20 years.

Kiwi are by far the smallest living ratites. All kiwi species are endangered. The kiwi is also a national symbol of New Zealand. The kiwi lays the largest egg in comparison to its body size.

LINE FOLLOWER ROBOT

LINE FOLLOWER ROBOT
( Robot Pengikut Garis )


Robot pengikut garis atau disebut juga Line Follower, merupakan sebuah rangkaian dari berbagai komponen elektronika yang dirangkai secara analog.
Robot ini mempunyai kemampuan untuk mengikuti sebuah garis di mana warna garis tersebut berlawanan denagn warna garis latarnya. Misalnya, garis berwarna hitam dan latar berwarna putih, atau kebalikan.
Untuk bekerja, robot ini membutuhkan tegangan kira-kira 12 volt. Sensor pada robot ini ada 4 buah. 3 buah untuk melacak garis sedangkan 1 buah untuk menambah kecepatan jalan pada robot.

Keistimewaan pada robot ini terletak pada IC-nya. IC jenis ini, bukan IC analog yang sudah terisi perintah-perintah seperti pada Light Follower. Untuk mengatur kecepatan robot, ketajaman saat berbelok, pengaturan batas sinar yang diterima sensor, dan yang lainnya tim menggunakan program yang ada di computer dan dikerjakan dengan bahasa C ( Computer ). Setelah selesai memprogram, data yang telah dibuat didownload ke robot. Robot dapat bergerak sesuai ketelitian pembuat dalam mengisikan angka ketajaman pada data yang dimasukkan ke IC.
