BAGAIMANA MEMILIH LAMPU HEMAT ENERGI
Di tempat kerja, sekitar 30% dari tagihan listrik yang telah dihabiskan pada pencahayaan ruang. Mengurangi jumlah konsumsi juga
Di tempat kerja, sekitar 30% dari tagihan listrik yang telah dihabiskan pada pencahayaan ruang. Mengurangi jumlah konsumsi juga dapat menghemat banyak uang dan juga dapat membantu mengurangi jejak karbon Anda. Ada tiga cara di mana seseorang dapat mengurangi jumlah energi yang dikonsumsi dari pencahayaan :
Kurangi jumlah lampu: tempat kerja Kebanyakan terlalu berlebihan menyala. Hal ini biasanya sebagai hasil dari pencahayaan tukang lebih menentukan persyaratan atau lebih jahat, menjual lampu lebih untuk dapat meningkatkan keuntungan mereka dari fit-out. Sebuah tempat kerja yang khas membutuhkan kualitas cahaya yang baik (hangat, tidak terlalu putih) yang telah memiliki output pencahayaan approx. 600 lux. Saya menantang Anda untuk mendapatkan lux meter dan menguji keluaran cahaya Anda – kemungkinan dalam 1000s tersebut. Untuk dapat mengatasi masalah yang satu ini cukup dapat hanya delamp (menghapus lampu) dari daerah yang lebih dari menyala. Jika salah satu dihapus 50 36W lampu neon dari kantor, tabungan akan setara dengan 2,5 ton CO2e (yaitu setara dengan menghapus sebuah mobil ukuran rata-rata dari jalan selama setahun)
Kurangi jumlah lampu yang tersisa pada: Biasanya lampu di tempat kerja yang tersisa di dalam kamar kosong / ruang pertemuan dan keluar dari jam kantor. Instalasi sensor cahaya (PIR, gerakan, audio atau sensor luminance) atau menjalankan matikan kampanye dapat secara dramatis mengurangi jumlah waktu yang tersisa pada lampu di ruang yang tidak terpakai
Beralih ke teknologi pencahayaan alternatif yang lebih efisien: Saat ini ada banyak energi alternatif pencahayaan efisien yang telah memberikan output cahaya yang cocok untuk sebagian kecil dari konsumsi. Apakah saya mendukung – waktu berikutnya Anda menghidupkan lampu pijar atau lampu halogen, meletakkan tangan Anda dekat cahaya dan merasakan panas. Ini akan terik panas. Mengapa? Karena 90% dari energi yang digunakan untuk dapat menghasilkan cahaya pada kenyataannya diubah menjadi panas. Hal ini sangat tidak efisien – menggunakan energi untuk dapat menciptakan cahaya bahwa sebenarnya menciptakan panas. Alternatif yang efisien energi yang baik termasuk lampu neon kompak (CFL) yang dapat menggantikan incandescents, dan LED (Light Emitting Dioda) yang dapat menggantikan halogen. Lampu LED masih teknologi yang relatif baru lahir Namun, ada sejumlah produk baik yang satu sekarang dapat mengambil di toko DIY lokal yang bertahan lebih lama daripada teknologi yang lebih tua dan memberikan output cahaya yang layak.
Rekomendasi saya adalah untuk dapat menguji beberapa lampu untuk kesesuaian sebelum berinvestasi.
Jika Anda telah memiliki tempat kerja sangat terang itu benar-benar menghabiskan waktu berharga dan usaha untuk mendapatkan kebutuhan pencahayaan yang benar.
MENYEGERAKAN IBADAH HAJI
Bagi orang yang telah memiliki kemampu-an dan memenuhi segala persyaratan, wajib untuk segera melaksanakan ibadah haji. Hal ini
Bagi orang yang telah memiliki kemampu-an dan memenuhi segala persyaratan, wajib untuk segera melaksanakan ibadah haji. Hal ini berdasarkan sabda Nabi Shalallaahu alaihi wasalam :
"Barangsiapa hendak melaksanakan haji, hendaklah segera ia lakukan, karena terkadang seseorang itu sakit, binatang (kendaraannya) hilang, dan adanya suatu hajat yang menghalangi."( HR. Ibnu Majah, dan dishahihkan oleh al-Albani. Lihat Shahih Ibni Majah No. 2331))
Dan sabda beliau:
"Bersegeralah melaksanakan haji, karena sesungguhnya salah seorang di antara kamu tidak mengetahui apa yang akan merinta-nginya."( HR. Ahmad dan dihasankan oleh al-Albani dalam Irwaa-ul Ghaliil No. 990).)
Ghostly Voices From Thomas Edisonís Dolls Can Now Be Heard
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.
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.
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.
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.
Top News Chinaís Intents Are Questioned as It Builds in Antarctica
HOBART, Tasmania — Few places seem out of reach for China’s leader, Xi Jinping, who has traveled from European capitals to obscure Pacific and Caribbean islands in pursuit of his nation’s strategic interests.
So perhaps it was not surprising when he turned up last fall in this city on the edge of the Southern Ocean to put down a long-distance marker in another faraway region, Antarctica, 2,000 miles south of this Australian port.
Standing on the deck of an icebreaker that ferries Chinese scientists from this last stop before the frozen continent, Mr. Xi pledged that China would continue to expand in one of the few places on earth that remain unexploited by humans.
He signed a five-year accord with the Australian government that allows Chinese vessels and, in the future, aircraft to resupply for fuel and food before heading south. That will help secure easier access to a region that is believed to have vast oil and mineral resources; huge quantities of high-protein sea life; and for times of possible future dire need, fresh water contained in icebergs.
It was not until 1985, about seven decades after Robert Scott and Roald Amundsen raced to the South Pole, that a team representing Beijing hoisted the Chinese flag over the nation’s first Antarctic research base, the Great Wall Station on King George Island.
But now China seems determined to catch up. As it has bolstered spending on Antarctic research, and as the early explorers, especially the United States and Australia, confront stagnant budgets, there is growing concern about its intentions.
China’s operations on the continent — it opened its fourth research station last year, chose a site for a fifth, and is investing in a second icebreaker and new ice-capable planes and helicopters — are already the fastest growing of the 52 signatories to the Antarctic Treaty. That gentlemen’s agreement reached in 1959 bans military activity on the continent and aims to preserve it as one of the world’s last wildernesses; a related pact prohibits mining.
But Mr. Xi’s visit was another sign that China is positioning itself to take advantage of the continent’s resource potential when the treaty expires in 2048 — or in the event that it is ripped up before, Chinese and Australian experts say.
“So far, our research is natural-science based, but we know there is more and more concern about resource security,” said Yang Huigen, director general of the Polar Research Institute of China, who accompanied Mr. Xi last November on his visit to Hobart and stood with him on the icebreaker, Xue Long, or Snow Dragon.
With that in mind, the polar institute recently opened a new division devoted to the study of resources, law, geopolitics and governance in Antarctica and the Arctic, Mr. Yang said.
Australia, a strategic ally of the United States that has strong economic relations with China, is watching China’s buildup in the Antarctic with a mix of gratitude — China’s presence offers support for Australia’s Antarctic science program, which is short of cash — and wariness.
“We should have no illusions about the deeper agenda — one that has not even been agreed to by Chinese scientists but is driven by Xi, and most likely his successors,” said Peter Jennings, executive director of the Australian Strategic Policy Institute and a former senior official in the Australian Department of Defense.
“This is part of a broader pattern of a mercantilist approach all around the world,” Mr. Jennings added. “A big driver of Chinese policy is to secure long-term energy supply and food supply.”
That approach was evident last month when a large Chinese agriculture enterprise announced an expansion of its fishing operations around Antarctica to catch more krill — small, protein-rich crustaceans that are abundant in Antarctic waters.
“The Antarctic is a treasure house for all human beings, and China should go there and share,” Liu Shenli, the chairman of the China National Agricultural Development Group, told China Daily, a state-owned newspaper. China would aim to fish up to two million tons of krill a year, he said, a substantial increase from what it currently harvests.
Because sovereignty over Antarctica is unclear, nations have sought to strengthen their claims over the ice-covered land by building research bases and naming geographic features. China’s fifth station will put it within reach of the six American facilities, and ahead of Australia’s three.
Chinese mappers have also given Chinese names to more than 300 sites, compared with the thousands of locations on the continent with English names.
In the unspoken competition for Antarctica’s future, scientific achievement can also translate into influence. Chinese scientists are driving to be the first to drill and recover an ice core containing tiny air bubbles that provide a record of climate change stretching as far back as 1.5 million years. It is an expensive and delicate effort at which others, including the European Union and Australia, have failed.
In a breakthrough a decade ago, European scientists extracted an ice core nearly two miles long that revealed 800,000 years of climate history. But finding an ice core going back further would allow scientists to examine a change in the earth’s climate cycles believed to have occurred 900,000 to 1.2 million years ago.
China is betting it has found the best location to drill, at an area called Dome A, or Dome Argus, the highest point on the East Antarctic Ice Sheet. Though it is considered one of the coldest places on the planet, with temperatures of 130 degrees below zero Fahrenheit, a Chinese expedition explored the area in 2005 and established a research station in 2009.
“The international community has drilled in lots of places, but no luck so far,” said Xiao Cunde, a member of the first party to reach the site and the deputy director of the Institute for Climate Change at the Chinese Academy of Meteorological Sciences. “We think at Dome A we will have a straight shot at the one-million-year ice core.”
Mr. Xiao said China had already begun drilling and hoped to find what scientists are looking for in four to five years.
To support its Antarctic aspirations, China is building a sophisticated $300 million icebreaker that is expected to be ready in a few years, said Xia Limin, deputy director of the Chinese Arctic and Antarctic Administration in Beijing. It has also bought a high-tech fixed-wing aircraft, outfitted in the United States, for taking sensitive scientific soundings from the ice.
China has chosen the site for its fifth research station at Inexpressible Island, named by a group of British explorers who were stranded at the desolate site in 1912 and survived the winter by excavating a small ice cave.
Mr. Xia said the inhospitable spot was ideal because China did not have a presence in that part of Antarctica, and because the rocky site did not have much snow, making it relatively cheap to build there.
Anne-Marie Brady, a professor of political science at the University of Canterbury in New Zealand and the author of a soon-to-be-released book, “China as a Polar Great Power,” said Chinese scientists also believed they had a good chance of finding mineral and energy resources near the site.
“China is playing a long game in Antarctica and keeping other states guessing about its true intentions and interests are part of its poker hand,” she said. But she noted that China’s interest in finding minerals was presented “loud and clear to domestic audiences” as the main reason it was investing in Antarctica.
Because commercial drilling is banned, estimates of energy and mineral resources in Antarctica rely on remote sensing data and comparisons with similar geological environments elsewhere, said Millard F. Coffin, executive director of the Institute for Marine and Antarctic Studies in Hobart.
But the difficulty of extraction in such severe conditions and uncertainty about future commodity prices make it unlikely that China or any country would defy the ban on mining anytime soon.
Tourism, however, is already booming. Travelers from China are still a relatively small contingent in the Antarctic compared with the more than 13,000 Americans who visited in 2013, and as yet there are no licensed Chinese tour operators.
But that is about to change, said Anthony Bergin, deputy director of the Australian Strategic Policy Institute. “I understand very soon there will be Chinese tourists on Chinese vessels with all-Chinese crew in the Antarctic,” he said.
