*Masa Kadaluwarsa Tabung LPG*

Beberapa orang mungkin sudah mengetahui hal ini; tetapi mungkin banyak
juga yang belum tahu. Apakah kita mengetahui bahwa ada juga suatu
tanggal kadaluwarsa untuk tabung LPG. Tabung yang sudah kadaluwarsa
tidaklah aman untuk digunakan dan
bisa menyebabkan kecelakaan seperti
yang baru saja terjadi di suatu kawasan di Jakarta Bulan yang lalu
(Tabung Gas meledak). Mengenai hal ini berhati-hati ketika menerima
tabung LPG dari penjual manapun.

Berikut ini adalah bagaimana kita dapat memeriksa masa kadaluwarsa dari
tabung LPG, tanggal kadaluwarsa
ditulis dalam alfa code sesuai nomornya
sebagai A atau B atau C atau D dan sekitar dua digit angka mengikutinya,

Contohnya:
D 06

Abjad mewakili empat bulanan (1
kwartal),


A untuk bulan Maret,
B untuk bulan Juni,
C untuk bulan September dan
D untuk bulan Desember


Dua digit angka berikutnya merupakan tahun kadaluwarsa.

Makanya "D06 berarti Desember 2006".

Sebarkan pengetahuan ini, siapa tahu bermanfaat.. .


Parasetamol Menyebabkan Asma pada Anak

Bayi dan balita yang diberi obat penurun panas dan nyeri parasetamol memiliki kemungkinan besar terserang asma atau eksem ketika mereka menginjak usia sekolah dasar. Hal ini disimpulkan oleh suatu penelitian terbaru. "Akan tetapi para orang tua tidak perlu cemas, dan jangan pula berhenti menggunakan parasetamol bila anak mereka demam, karena penelitian ini belum terlalu jelas menjelaskan apakah parasetamol saja yang menyebabkan asma dan eksem ini", kata seorang ahli pernafasan di Australia.

Penelitian ini, yang dipublikasikan oleh The Lancet, menunjukkan bahwa penggunaan parasetamol pada anak umur satu tahun dapat meningkatkan risiko terkena penyakit alergi (asma/eksem) ketika anak tersebut menginjak umur 7 tahun. Kemungkinannya adalah 50%.

"Anak yang lebih sering diberi parasetamol memiliki kemungkinan sebesar 3 kali lipat terkena asma dan reaksi alergi pada hidung (rhino conjunctivitis) , serta kemungkinan terkena eksem sebesar 2 kali lipat", kata Prof. Richard Beasley, ketua tim peneliti pada Medical Research Institute di Selandia Baru.

Penelitian ini melibatkan 200 ribu anak dari 31 negara, dan dianggap dapat menjelaskan misteri mengenai meningkatnya kasus asma pada anak-anak di Australia dan Selandia Baru sepanjang masa 50 tahun terakhir ini.

Namun Prof. Beasley mengatakan juga bahwa penelitian ini masih harus ditopang oleh penelitian sejenis yang lain, sehingga saat ini hasil penelitian tersebut belum dianggap cukup kuat untuk menghentikan pemakaian parasetamol.

Hasil penelitian Prof. Beasley tersebut mendukung rekomendasi World Health Organization (WHO) baru-baru ini yang menyatakan agar parasetamol tidak digunakan secara rutin, namun hanya untuk kondisi demam yang benar-benar tinggi.

Dr. Raymond Mullins, seorang konsultan kesehatan dan presiden pada Australasian Society for Clinical Immunology and Allergy mengatakan bahwa penemuan ini adalah fenomena yang menarik yang berpotensi mengubah metode pengobatan demam.

Akan tetapi peneliti lain, yaitu Dr. Adrian Lowe, menyatakan bahwa mungkin ada penjelasan lain mengenai penyebab asma ini. "Ada sejumlah infeksi yang dikaitkan juga dengan terjadinya asma pada anak-anak, jadi pada penelitian demikian adalah sangat sukar untuk menentukan apakah parasetamol ataukah juga infeksi tertentu yang menyebabkan kasus asma tersebut".

DDR2 VS DDR3

About three years ago DDR2 memory first appeared on the desktop PC scene. It would be impossible to say it burst on the scene since it was introduced with the unimpressive Intel NetBurst processors. In that market DDR2 was more like a trickle since it was mainly a curiosity for a processor that was running a distant second place to the leading AMD Athlon chips, which were still powered by DDR memory.

DDR2 finally became the universal standard last May/June when AMD switched to DDR2 on their new AM2 platform and Intel introduced Core 2 Duo, the new CPU performance leader. Core 2 Duo resided on socket 775, which also was fed by DDR2. While it sometimes seems like centuries ago, it is worth remembering that Intel Core 2 Duo regained the CPU performance crown less than a year ago, and the two years prior to that all the fastest systems used AMD Athlon 64/X2/FX processors.

We compared performance of DDR2 on the new platforms in July of last year. AM2 provided better bandwidth with DDR2, but the better AM2 bandwidth did not translate into better performance. Since Core 2 Duo was faster at the same timings, it appeared the Intel Core 2 Duo architecture was not particularly bandwidth hungry and that it made very good use of the DDR2 bandwidth that was available with the chipset memory controller.

Since last May/June DDR2 has finally turned the market, and it has made some remarkable transformations along the way. The early 5-5-5 timings at the official DDR2-800 speed have since been replaced by several high performance memories capable of 3-3-3 timings at DDR2-800. The best memory at DDR2-1066 can now operate at 4-4-3 timings, and the fastest DDR2 is now around DDR2-1266 and still getting faster.

Perhaps even more remarkable, in the last year DDR2 memory prices have dropped to half of what they once were (sometimes more), and today DDR2 is often cheaper than the DDR memory it replaced. Compared to the very expensive prices at launch and into the holiday buying season we see DDR2 is now the memory price standard in the desktop computer market.

Fast forward a year and Intel is now launching their first chipsets to support DDR3 memory. In one of the sloppiest NDA launches in recent memory we already have P35 boards for sale since early May. The official chipset introduction is scheduled for May 21st and boards are "officially" launching into the retail channel on June 4th.

We can tell you that Intel does not really have an NDA, but they have been very aggressive in holding first tier manufacturers to a May 21st performance embargo and retail distribution on June 4th. Despite that, people around the world have been able to buy P35 boards from several retailers. We have retail boards we bought on the open market, which makes the 21st NDA a moot point in our opinion. Still, we value our relationship with both Intel and the major board makers, so this will not be a full P35 launch review. You will see that coming on May 21st.

What this review does address is the performance of the new DDR3 memory that is launched with P35. The new Intel P35 chipset, known as Bearlake during development, supports either DDR2 or DDR3 memory. This presented a perfect opportunity to look at the performance of both DDR3 and DDR2 on the new P35 chipset. We were also able to compare performance to a Gold Editors' Choice Intel P965 motherboard. The results of these comparisons provided interesting results about the capabilities of the new P35 memory controller. It also answered the question of whether you should care about DDR3 in any upcoming system purchase.
