Children Now The Weak? - Health Information

Children Now The Weak?

A UK study indicated that children today tend to be "weak" and the difficulty performing physical tasks are actually easier for them the previous generation.Research experts at Essex University shows that children aged 10 years in the era now have weaker muscles than children who were born a decade earlier.Researchers estimate, it is most likely due to changes in lifestyle, in which the children of today would rather move indoors, such as playing computer or games. While children in the past more playing in open space with a variety of physical activities, like climbing trees, climbing stairs, or hang from iron rods in the park.As reported in the journal Acta Paediatrica, children now tend to have trouble doing movements such as hanging on the staircase wall or sit-ups in a matter that much. In addition to decline in terms of strength, the children are now too difficult to grip things properly.Research was initiated by Dr Gavin Sandercock, child fitness experts from Essex University, was conducted by comparing the results of tests the ability of two groups of children in different eras. The first group is those aged 10 years in 2008 and the second group is the 10 year olds in 1998.Research shows, children's ability to do sit-ups as much as 27.1 percent decline. Hand muscle strength also decreased 26 percent and the traction of children to decline 7 percent.Moreover, if in 1998 one in 20 children are not able to hold his weight when hanging from the staircase wall, lapse a decade later recorded one of 10 children unable to do so."This may be due to changes in activity patterns among British children aged 10 years. For example, lack of activity such as climbing trees or climbed the rigging to have fun. In particular, activities such as this can increase the strength of the children and make them able to lift and hold their own weight. The fact that 10 percent of children failing the test staircase wall and another 10 percent refused to do so shocking, "says Dr Sandercock.The study also found that two groups of children have the same body mass. This means that children aged 10 years today seem to have more fat and muscle mass is lower than the previous generation.

Garam Juga Punya Efek Candu

Jarang ada orang yang menyukai makanan yang tidak dibubuhi garam karena rasannya pasti hambar. Harus diakui memang sulit untuk melakukan diet garam. Salah satu penyebabnya adalah karena garam punya efek candu seperti halnya rokok dan narkoba.

Para ilmuwan dari Australia dan Amerika menemukan ketika tubuh ketagihan garam aktivitas otak akan memicu gen dan sel-sel otak yang sama seperti pada ketagihan rokok dan narkoba. Penelitian itu dilakukan terhadap tikus di laboratorium. Tikus-tikus itu sebagian diberi makanan rendah garam dan sebagian diberi garam. Kemudian aktivitas otak tikus itu dibandingkan. Para peneliti juga meneliti aktivitas otak tikus yang puasa garam selama 3 hari kemudian diberi minuman yang mengandung garam.

Ketika tikus menginginkan garam, sel otak mereka menghasilkan protein lebih banyak, serupa dengan adiksi pada zat-zat seperti heroin, kokain dan nikotin. Kemudian gejala ketagihan garam mereda beberapa saat setelah tikus itu diberi garam, bahkan sebelum garam mencapai lambung, masuk ke peredaran darah dan sampai di otak.

Yang mengagumkan adalah bahwa gen yang pasif akibat kekurangan sodium langsung hidup kembali dalam beberapa menit setelah mendapat garam. Hal itu juga bagian dari evolusi mekanisme pertahanan diri binatang. Karena saat mereka kehausan dan menemukan sumber air, mereka akan segera menghabiskan air dan pergi agar tidak ditangkap predator.

Kebanyakan Garam Rugikan Kesehatan

Garam dalam masakan memang berperan besar untuk menimbulkan rasa yang lezat dan gurih, namun dalam jumlah yang tinggi garam menjadi pemicu beberapa masalah kesehatan, mulai dari darah tinggi sampai gagal ginjal.

Garam dapur atau garam dalam pengertian sehari-hari adalah jenis garam yang terdiri dari unsur mineral natrium (Na) alias sodium dan klorida (Cl) yang bergabung menjadi satu molekul bernama natrium klorida (NaCl). Jumlah sodium dalam garam dapur sekitar 40 persen dan sisanya ion klorida.

Sodium atau natrium tersebut dibutuhkan tubuh untuk proses metabolisme, menjaga regulasi volume dan tekanan darah, serta kontraksi otot dan transmisi sel saraf. Kendati demikian, konsumsi garam pada tiap orang dianjurkan tidak lebih dari 6 gram (setara 1 sendok teh) setiap hari. Berdasarkan Pedoman Gizi Seimbang jumlah 6 gram itu sama dengan 2300 mg natrium. Yang menjadi masalah kesehatan sebenarnya adalah natrium, bukan garam secara keseluruhan.

Asupan garam yang tinggi ini berkaitan erat dengan terjadinya tekanan darah tinggi. Riset menunjukkan kenaikan setengah sendok teh garam akan menaikkan tekanan sistolik 5 poin dan tekanan diastolik 3 poin. Sebaliknya mengurangi garam menjadi kurang dari 1 sendok teh akan menurunkan tekanan sistolik 7 poin dan diastolik 4 poin.

Selain memicu hipertensi konsumsi garam yang tinggi juga bisa mengganggu kerja ginjal. Sebenarnya tubuh punya mekanisme untuk mengeluarkan kelebihan garam, tapi karena tingginya garam yang diasup ginjal jadi kesulitan untuk mengeluarkan. Akibatnya jumlah natrium di dalam tubuh sangat banyak. Padahal, natrium memiliki sifat mengikat cairan (retensi cairan).

Ketika jumlah natrium dalam tubuh tinggi, maka jumlah cairannya ikut meningkat sehingga volume darah bertambah dan tekanannya semakin besar. Jika ditambah dengan konsumsi lemak berlebih yang mengakibatkan pembuluh darahnya mengecil, akibatnya bisa fatal karena pembuluh darahnya bisa pecah. Beberapa penelitian juga menunjukkan asupan garam yang tinggi akan mempercepat perburukan fungsi ginjal terutama pada pasien-pasien penyakit ginjal. Itu sebabnya kita disarankan untuk mulai menjaga jarak dengan garam dan mengonsumsi lebih banyak sayuran dan buah.

WD Scorpio Black 750GB Laptop HDD

You can never have enough storage and if you primarily use a notebook you more than likely know that storage space is a precious commodity. Most pre-configured notebooks that are available at brick and mortar stores come with 250GB or 320GB hard drives is seems. That may sound like a bunch of space when you are standing in the store, but after you put all your programs, games and digital media on the drive it usually doesn't leave you with much space for future growth. If you have reached or are nearing full capacity on your storage drive then you might want to consider upgrading to a larger 750GB or 1TB 2.5" notebook hard drive. If you are after performance then you'll want to stick to a 750GB drive as they are available at 7200 RPM and offer the fastest data transfers possible on a notebook hard drive. If you don't really care about performance and just want as much storage space as you can get in a 2.5" notebook drive then a 1TB 5200 RPM hard drive is the ideal choice for you.

Today, we'll be looking at a the WD Scorpio Black WD7500BPKT 750GB 7200 RPM 2.5" SATA notebook hard drive. With a 7200 RPM drive speed, 16MB cache, and 3 GB/s SATA interface speed, the 750GB Western Digital Scorpio Black hard drive is the largest 7200 RPM drive that Western Digital offers right now. When it comes to pricing, the WD Scorpio Black 750GB Hard Drive retails online for $104.98 shipped, which makes it $0.14 per Gigabyte. For comparison sake the Western Digital Scorpio Blue 5400 RPM 750GB notebook hard drive can be purchased online for just $89.99 shipped, which comes out being $0.12 per Gigabyte. If you are looking for more performance then the cost for that speed is only a couple pennies per Gigabyte, which isn't going to break the bank for most people.

The WD Scorpio Black 750GB is sold under the part number WD7500BPKT, and is obviously part of the Black series. WD has color coded their products, which makes is easy to see who they are aimed at. Their mainstream products are called “Blue,” power-efficient drives are named “Green,” and high-performance drives are called “Black.” All of the WD Black drives spin at 7,200 RPM, utilize a SATA/300 interface with Native Command Queuing (NCQ) support, and have 16 MB of cache memory. Those not needing performance like this should look at the Scorpio Blue series as they feature 5,400 RPM drive speeds (5,200 RPM on some), 8 MB of cache memory and a slightly lower prices.
WD Scorpio Black WD7500BPKT Hard Drive Features:

• Form Factor: 2.5" x 1/8H (100mm x 69.85 x 9.5mm)
  
• Capacity: 750 GB
  
• Interface Type: Serial ATA-300
  
• Buffer Size: 16 MB
  
• Features: Native Command Queuing (NCQ)
  
• Seek Time: 12.0 ms (average)
  
• Average Latency: 4.20 ms (nominal)
  
• Spindle Speed: 7200 RPM
• Noise Level: 28dBA at idle and 28dBA in seek mode 0
  
• Power Use: 1.75 Watts Read/Write, 0.80 Watts at idle and 0.20 Watts Sleep/Standby
  
• Manufacturer Warranty: 5 year limited warranty
  

The WD Scorpio Black 750GB uses three 250GB platters to reach the full capacity rating of the drive, which is impressive for a drive of this size. What is also impressive is the 12.0 ms average seek time! The back of this 2.5" notebook hard drive is pictured above and gives a better look at the SATA power connector and the SATA NCQ interface.

The WD Scorpio Black is the first WD notebook drive that we have tested that uses 'Advanced Format' technology. For years now most hard drives have written data blocks in traditional 512 byte sectors. Over the past three years the industry have been moving to a larger sector size of 4 kilobytes (4,096B) for obvious reasons. The Advanced Format (AF) nomenclature that WD is using is just their way to ID what drivers are using 4KB sectors. If you purchase this hard drive and install a brand new operating system on it from scratch then you won't even notice the changes, but if you are cloning an older storage drive to the WD Scorpio Black 750GB drive that we have here or any WD Advanced Format drive you will have to run the WD Advanced Format Hard Drive Download Utility as you need to properly align the drive after the cloning is done.

To show you the performance of this drive and how to do the drive alignment we will be using a retail Sony VAIO Y Series notebook. This notebook came with a Hitachi 320GB 5400RPM hard drive that is slow and the drive uses 512b sectors and after using Acronis backup software we'll have to align the WD drive to get optimal performance from it! First run read/write performance tests on both of the bare drives so you can see how the drives perform and then we'll get to the cloning and another quick look at the performance of the drives in the Sony VAIO Y series notebook.

Memory Performance on AMD's A-Series APU

Last month Legit Reviews reviewed the AMD A8-3850 'Llano' APU and our article looks like it was well received by our readers with the exception of one thing. We've had a number of readers write in saying that it was great that we tested this platform with 1866MHz memory, but they are building budget systems and want to use 1333MHz or 1600MHz memory. It is true that we didn't look at performance numbers of AMD's A-Series APUs on the A75 chipset at 1333MHz, 1600MHz and since this platform is very budget friendly we see this as a valid point.

Legit Reviews does not want to ostracize any of our readers and pride ourselves on our no-BS straight forward and honest reviews, so we went back to the drawing board to get you the performance data you need before ordering in a new platform. We'll be using the Gigabyte GA-A75-UD4H motherboard for testing again, but since we updated the BIOS to version F3 we re-did all of the performance numbers as we did see improved performance with the new BIOS.

We also got a few questions about how the platform handles 16GB of memory and if there are any stability issues with running all four memory slots fully populated. We've seen performance gains with all the memory slots full on AMD platforms in the past, so we'll be looking at 2x4GB and 4x4GB performance as well in our test results. Not too many people will be running 16GB of memory on the Llano A-Series APU, but we found no issues in doing so with G.Skill Ripjaws

So, to reiterate what our goals are for this article one more time:

• Benchmark 2x4GB memory kits at 1333MHz, 1600MHz, 1866MHz to find performance differences
• Benchmark 2x4GB versus 4x4GB to see if filling all the memory slots impacts performance
• See if we have any issues running 16GB of memory

This should be easy enough, so let's take a look at the test system and get right to the performance numbers.

Intel Core i3-2120 CPU - BX80623I32120

Last week when we reviewed the AMD A-Series Llano A8-3850 APU we had a bunch of readers wanting to see performance compared to more Intel Sandy Bridge processors. One of the processors that we were asked about was the Intel Core i3-2120, which retails for $149.68 and is one of the most popular budget-minded processors in the Intel arsenal today. We heard you and have gotten our hands on a retail boxed Intel Core i3-2120 processor to see how it performs against the Intel Core i3-2105, Core i7-2600k and the AMD A8-3850 APU. Before we jump into the benchmarks and testing we should at least show you the basic features of this processor and what comes with the retail boxed version.

The Intel Core i3-2120 is based on the 32nm 'Sandy Bridge' architecture and is a 3.3GHz dual-core processor with Hyper-Threading. The CPU does have a GPU on it and that would be the Intel HD Graphics 2000, which runs between 850MHz and 1100MHz thanks to a dynamic clock cycle. The multiplier is locked on the Core i3-2120 processor as it is not part of the 'K-series' of processors that are aimed at enthusiasts with unlocked multipliers.
Intel Core i3-2120 CPU Specifications:

• Model #: BX80623I32120
• S-spec: SR05Y
  
• Launch Date: Q1'11
• Processor Number: i3-2120
• Supported Socket: LGA1155
  
• # of Cores: 2
• # of Threads: 4
• Clock Speed: 3.3 GHz
• Intel Smart Cache: 3 MB
• Bus/Core Ratio: 33
• Instruction Set: 64-bit
• Instruction Set Extensions: SSE4.1/4.2, AVX
• Turbo Core: No
• Hyper-Threading Technology: Yes
  
• Lithography: 32 nm
• Processor Graphics: Intel HD Graphics 2000
• Graphics Base Frequency: 850MHz
  
• Graphics Max Dynamic Frequency: 1100MHz
  
• Max TDP: 65 W
• Recommended Channel Price: $138.00

Since our review sample it the retail box Core i3-2120 (part number BX80623I32120) the processor comes with a CPU cooler along with a three year limited warranty. If you buy a tray processor you do not get the Heatsink Fan combo or the longer warranty.

As you can see this Intel Core i3-2120 is not an Engineering Sample processor and batch number of L047B255. You can also see the S-Spec number SR05Y on the integrated heat spreader (IHS) and that it was made in the country of Malaysia.

The Intel Core i3-2120 processor is designed for LGA1155 platforms and has a slightly different arrangement of resistors on the bottom of the processor compared to some of the other Sandy Bridge processors since some use Intel HD Graphics 2000 and others use Intel HD Graphics 3000 graphics. In the image above you can see the difference between the Intel Core i3-2120 with Intel HD Graphics 2000 and the Intel Core i3-2105 and Core i7-2600K that use Intel HD Graphics 3000. If you want to use Intel Processor Graphics (PG) of the CPU you need to use a motherboard with the H67, or Z68 chipset that has video outputs and not the P67 based motherboards that don't support PG.

Windows 7 versus Windows XP on the ASUS Eee PC 1005HA Netbook - Windows 7 on a Netbook - Legit Reviews

Windows 7 on a Netbook

Many PC manufacturers, including netbook makers, are offering a free upgrade voucher for Microsoft's Windows 7 and it's time we found out how Windows 7 will perform on one of the most popular netbooks currently on the market! Using the release candidate, we installed Windows 7 on the ASUS Eee PC 1005HA seashell netbook and ran all the benchmarks we run in our full reviews in order to get a full impression on how Windows 7 stacks up against Windows XP on a netbook. Many in the community running netbooks are really hoping Windows 7 holds its own on a netbook because, let's face it, 2002's Windows XP on any 2009 system just seems backwards.

Installation

Armed with a 4 GB high-speed USB flash drive and step-by-step instructions by Kurt Shintaku, we were easily able to install Windows 7 on the 1005HA. We first burned the Windows 7 RC image to a DVD, but you could easily mount the ISO to a virtual drive instead. Following the linked instructions, we created a bootable Windows 7 installation flash drive with no issues.
Now, since the flash drive is detected as a removable hard disk to the computer, we had to edit the BIOS settings in order to make the flash drive the primary hard disk. Once we did this, the Windows 7 installer booted right up and we were able to begin our Windows 7 installation just as any other. There is a slight trick, though, as once the installer copies the initial set of files to the hard disk and reboots, you must enter the BIOS again and set the internal hard drive back to the primary so it is the one that boots. Besides that, installing Windows 7 was a breeze.
Windows 7 had drivers installed for all of our hardware right out of the box except the ACPI driver which allows the blue function hot keys to all work correctly. However, after a number of updates, Windows 7 actually knew that we had not installed the ACPI driver yet and pointed us directly to ASUS' ACPI driver which we downloaded and installed and it worked perfectly. I would also recommend installing the Intel Graphics driver from the optional Windows updates as it does install some additional files used by the ASUS ACPI driver.
Now that we have explained how we have installed Windows 7 on the ASUS Eee PC 1005HA seashell, let's see how it performed against the pre-installed Windows XP installation!
