saco-indonesia.com, Kuasa hukum tersangka dalam kasus suap Pemilukada Lebak, Ratu Atut Chosiyah, TB Sukatma, juga mengatakan kliennya telah diperiksa oleh Komisi Pemberantasan Korupsi (KPK) dalam kasus dugaan suap pada Pemilukada Lebak, Banten.

"Diperiksa sebagai saksi (dalam jadwal KPK sebagai tersangka). Untuk kasus Lebak," kata Sukatma di Gedung KPK, Jumat (27/12/2013).

Pemeriksaan itu terkait dengan adanya keterlibatan Tubagus Chairi Wardana alias Wawan, dan mantan Ketua Mahkamah Konstitusi (MK) Akil Mochtar. "Beliau juga harus mempelajari kembali dokumen yang berkaitan dengan perkara beliau maupun keterangan saksi-saksi lain," terangnya.

Atut sampai di KPK, sekira pukul 10.15 WIB tadi. Dia tak berikan komentar apapun, sang Gubernur itu langsung melenggang menuju ruang penyidikan.

Fungsi, Keunggulan, dan Kekurangan Rockwool

Fungsi Rockwool

Fungsi umum dari rockwool adalah untuk dapat memberikan isolasi di rumah tinggal atau bangunan komersial. Rockwool juga akan dapat melindungi pipa, kapal, rumah mobile dan peralatan memasak domestik. Meskipun paling umum dikenal untuk dapat menyediakan isolasi di rumah, orang juga akan menggunakan rockwool dan glasswool sebagai media tumbuh hortikultura.

Keunggulan Rockwool

Rockwool juga menyediakan berbagai keuntungan, termasuk tahan api dan serap suara. Karena serat yang tidak mudah terbakar dan telah memiliki titik leleh yang ekstrim lebih dari 2.150 derajat F, isolasi wol batuan bertindak sebagai penghalang api. Karakteristik tahan apinya menunda penyebaran api, yang bisa menambahkan menit berharga untuk dapat melarikan diri saat kebakaran. Batu isolasi wol juga menolak air, anti membusuk dan jamur, termasuk berbagai jenis pertumbuhan bakteri. Karena menolak air, rockwool tidak akan melemah atau kendur. Isi dari rockwool padat, sehingga dapat mengurangi aliran udara dan transmisi gelombang suara.

Keuntungan rockwool :

    Cocok untuk aneka kebutuhan industri
    Memiliki daya konduksi termal yang rendah
    Dapat digunakan pada suhu 100° C sampai 820° C
    Tidak mudah terbakar
    Kedap suara
    Tidak berkarat / berjamur

Aplikasi produk :

    Peredam ruangan genset
    Peredam ruangan studio
    Peredam ruangan diskotik
    Partisi ruangan

Tersedia dalam bentuk : Lembaran, Roll, Batang
Kekurangan rockwool :

Masalah kecil mungkin timbul ketika dalam melaksanakan isolasi/insulation. Ketika dalam menangani rockwool, hindari menyentuh langsung dengan tangan kosong. Meskipun tidak menimbulkan bahaya langsung, dapat menyebabkan gatal-gatal sementara dan ketidaknyamanan.

Juga, debu dapat bertebaran ketika memasang rockwool, sehingga harus memakai masker pelindung dan pelindung mata yang sesuai untuk dapat menghindari kecelakaan atau cedera, dan agar dapat bernafas dengan benar.

At the National Institutes of Health, Dr. Suzman’s signature accomplishment was the central role he played in creating a global network of surveys on aging.

Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.

The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.

In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.

Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.

Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.

Audio

The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.

In 2014, the technology was made available for the first time outside the laboratory.

“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”

Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.

The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.

“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.

The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.

Audio

Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.

Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.

At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.

“That was the Eureka moment,” Mr. Rolfs said.

In 1890, a girl in Edison’s laboratory had recited:

There was a little girl,

And she had a little curl

Audio

Right in the middle of her forehead.

When she was good,

She was very, very good.

But when she was bad, she was horrid.

Recently, the conservation center turned up another surprise.

In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.

Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.

“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.

The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.
