RU - 486 (Roussell - Uclaf)

RU - 486 (Roussell - Uclaf)

Cara menggugurkan kandungan dengan teknik ini hanya diperkenankan secara medis untuk usia kehamilan trisemester I. Sesuai dengan namanya, proses pengguguran kandungan dilakukan dengan mengkonsumsi PIL RU 486.

Secara teknis pil ini menggunakan 2 hormon sintetis (mifepristone dan misoprostol) yang secara kimiawi akan memicu induksi di usia kehamilan 5-9 minggu. Cara menggugurkan kandungan dengan RU 486 ini adalah pemblokiran hormon progesterone sehingga tidak ada nutrisi yang masuk ke plasenta dan janin. Dengan demikian janin tidak mendapat makanan dan tidak berkembang dengan baik.

Selang beberapa waktu setelah meminum PIL RU 486 tersebut biasanya wanita akan diberikan suntikan hormon prostaglanding yang memicu kontraksi rahim sehingga janin terlepas dari rahim. Setelah janin terlepas dari rahim wanita akan diperiksa lagi untuk mengetahui apakah aborsi/pengguguran kandungan telah terlaksana dengan sempurna atau belum. Jika aborsi belum terjadi dengan sempurna, maka dilakukan tindakan operasi untuk mengeluarkan janin/sisa janin dan plasenta dari rahim,

Menurut catatan statistik, teknik menggugurkan kandungan dengan penggunakan RU 486 (Roussell Uclaf) dapat mengakibatkan seorang wanita mengalami pendarahan hebat, pusing-pusing, mual muntah hingga berakibat pada kematian. kasus lain tercatat bahwa penggunaan pil tersebut dapat mengakibatkan serangan jantung.

Teknik menggugurkan kandungan dengan RU - 486 ini ternyata tidak saja mempengaruhi kehamilan yang sedang berlangsung tetapi dapat mempengaruhi kehamilan (yang diinginkan) berikutnya. Seorang ibu dapat mengalami keguguran spontan sampai dengan ancaman memiliki bayi cacat akibat rusaknya system hormon ibu.

How to download Internet Explorer 8 for Windows 7 E without any Web browser?

Windows 7 RTM will be available in the next days and for all European users there will be no Internet Explorer 8. I’m not sure if there will be an option to install Internet Explorer from the setup DVD or if we can simple add this as a Windows feature in control panel.

Following command line batch file will download Internet Explorer 8 setup:

Note: this is a first version of my script that will download Internet Explorer 8 German for Windows Vista (x86) only. If it is working I will modify it to have an option to choose the correct version you need. Well, if Microsoft is adding a checkbox to the Windows features in control panel we don’t need it.

4G Network

4G refers to the fourth generation of cellular wireless and is a successor to 3G and 2G standards. The rest of this article associates 4G with International Mobile Telecommunications-Advanced (IMT Advanced), though 4G is a broader term and could include standards outside IMT-Advanced. A 4G system may upgrade existing communication networks and is expected to provide a comprehensive and secure IP based solution where facilities such as voice, data and streamed multimedia will be provided to users on an "Anytime, Anywhere" basis and at much higher data rates compared to previous generations.

Objectives
4G is being developed to accommodate the QoS and rate requirements set by forthcoming applications like wireless broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, HDTV content, Digital Video Broadcasting (DVB), minimal services like voice and data, and other services that utilize bandwidth.

Approaches
As described in 4G consortia including WINNER, WINNER - Towards Ubiquitous Wireless Access, and WWRF, a key technology based approach is summarized as follows, where Wireless-World-INitiative-NEw-Radio (WINNER) is a consortium to enhance mobile communication systems.

4G features
According to the members of the 4G working group, the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented. Although legacy systems are in place to adopt existing users, the infrastructure for 4G will be only packet-based (all-IP). Some proposals suggest having an open Internet platform. Technologies considered to be early 4G include: Flash-OFDM, the 802.16e mobile version of WiMax (also known as WiBro in South Korea), and HC-SDMA (see iBurst). 3GPP Long Term Evolution may reach the market 1–2 years after Mobile WiMax is released.

An even higher speed version of WiMax is the IEEE 802.16m specification. LTE Advanced will be the later evolution of the 3GPP LTE standard.

COMPONENTS
Access schemes
As the wireless standards evolved, the access techniques used also exhibited increase in efficiency, capacity and scalability. The first generation wireless standards used plain TDMA and FDMA. In the wireless channels, TDMA proved to be less efficient in handling the high data rate channels as it requires large guard periods to alleviate the multipath impact. Similarly, FDMA consumed more bandwidth for guard to avoid inter carrier interference. So in second generation systems, one set of standard used the combination of FDMA and TDMA and the other set introduced a new access scheme called CDMA. Usage of CDMA increased the system capacity and also placed a soft limit on it rather than the hard limit. Data rate is also increased as this access scheme is efficient enough to handle the multipath channel. This enabled the third generation systems to use CDMA as the access scheme IS-2000, UMTS, HSXPA, 1xEV-DO, TD-CDMA and TD-SCDMA. The only issue with CDMA is that it suffers from poor spectrum flexibility and scalability.

Recently, new access schemes like Orthogonal FDMA (OFDMA), Single Carrier FDMA (SC-FDMA), Interleaved FDMA and Multi-carrier code division multiple access (MC-CDMA) are gaining more importance for the next generation systems. WiMax is using OFDMA in the downlink and in the uplink. For the next generation UMTS, OFDMA is being considered for the downlink. By contrast, IFDMA is being considered for the uplink since OFDMA contributes more to the PAPR related issues and results in nonlinear operation of amplifiers. IFDMA provides less power fluctuation and thus avoids amplifier issues. Similarly, MC-CDMA is in the proposal for the IEEE 802.20 standard. These access schemes offer the same efficiencies as older technologies like CDMA. Apart from this, scalability and higher data rates can be achieved.

The other important advantage of the above mentioned access techniques is that they require less complexity for equalization at the receiver. This is an added advantage especially in the MIMO environments since the spatial multiplexing transmission of MIMO systems inherently requires high complexity equalization at the receiver.

In addition to improvements in these multiplexing systems, improved modulation techniques are being used. Whereas earlier standards largely used Phase-shift keying, more efficient systems such as 64QAM are being proposed for use with the 3GPP Long Term Evolution standards.

IPv6 support
Unlike 3G, which is based on two parallel infrastructures consisting of circuit switched and packet switched network nodes respectively, 4G will be based on packet switching only. This will require low-latency data transmission.

By the time that 4G is deployed, the process of IPv4 address exhaustion is expected to be in its final stages. Therefore, in the context of 4G, IPv6 support is essential in order to support a large number of wireless-enabled devices. By increasing the number of IP addresses, IPv6 removes the need for Network Address Translation (NAT), a method of sharing a limited number of addresses among a larger group of devices, although NAT will still be required to communicate with devices that are on existing IPv4 networks.

As of June 2009, Verizon has posted specifications that require any 4G devices on its network to support IPv6.

Advanced Antenna Systems
The performance of radio communications obviously depends on the advances of an antenna system, refer to smart or intelligent antenna. Recently, multiple antenna technologies are emerging to achieve the goal of 4G systems such as high rate, high reliability, and long range communications. In the early 90s, to cater the growing data rate needs of data communication, many transmission schemes were proposed. One technology, spatial multiplexing, gained importance for its bandwidth conservation and power efficiency. Spatial multiplexing involves deploying multiple antennae at the transmitter and at the receiver. Independent streams can then be transmitted simultaneously from all the antennae. This increases the data rate into multiple folds with the number equal to minimum of the number of transmit and receive antennae. This is called MIMO (as a branch of intelligent antenna). Apart from this, the reliability in transmitting high speed data in the fading channel can be improved by using more antennae at the transmitter or at the receiver. This is called transmit or receive diversity. Both transmit/receive diversity and transmit spatial multiplexing are categorized into the space-time coding techniques, which does not necessarily require the channel knowledge at the transmit. The other category is closed-loop multiple antenna technologies which use the channel knowledge at the transmitter

Software-Defined Radio (SDR)
SDR is one form of open wireless architecture (OWA). Since 4G is a collection of wireless standards, the final form of a 4G device will constitute various standards. This can be efficiently realized using SDR technology, which is categorized to the area of the radio convergence.

PSP Firmware 6.00 Decrypted and Analyzed
greg | September 11, 2009

The GEN team has de-crypty-crypted PSP firmware 6.00, analyzed those unencrypted bits and bytes, and has now shared their findings…

Here’s what up –

(Translated by way of Google Translate)

First:

We have therefore launched a program to compare files of 5.50 and 6.00. You see below the result which indicates that all files are different and have been recompiled (normal since the change of key), and you can see the newcomers of firmware 6.00 – Rated Only in (first) – and disappearance compared to 5.50 – Rated Only in (seconds).

For that list; see here.

Second:

The PRX system directory that you were all set to jou(?) and again, there is a change. Note the appearance of PRX following: codec_01g.prx, codec_02g.prx, codepage.prx, libgameupdate.prx, libmp4.prx, mlnbridge_msapp.prx, mp4msv.prx, np_campaign.prx, power_01g.prx, power_02g.prx, umdcache. prx, usb1seg.prx, usbdmb.prx) and disappearance of others codec.prx, idmanager.prx, impose.prx, power.prx, umdcache_02g.prx, usb1seg_02g.prx.

Third (Conclusion):

The first stage of the discovery of 6.00 has therefore been reached and our team of developers will therefore continue its investigations to try to bring us more information about this topic. Note that Dark_Alex said he was not working on 6.00 M33 and that for the moment, no public 6.00 GEN is still expected.

The “no public 6.00 GEN is still expected” throws me off… I’m not sure if that’s an error on Google Translate’s part or what. If anyone is able to provide a better, more accurate translation, please do so in the comments below. Thanks.

Props GEN.
