Older women who eat more chocolate are less likely to develop heart problems over a nearly 10 year period, new study findings report.
Women older than 70 who ate chocolate at least once a week were 35% less likely to be hospitalised or die from heart disease over the course of study, and nearly 60% were less likely to be hospitalised or die from heart failure.

Vertical Mill Coal Grinder 
Vertical Mill Coal GrinderCoal is widely used in the world. One of the major usage of coal is a major contribution to combustion at steel industries and thermal power plants.
Basically consumption of coal thermal plant is quite large. Imagine, normally plant with 2000MW using fine coal to generate electricity which the consumption of coal around 10,000 tonne to 15,000 tonne per day. That's why criteria for choosing coal mill is very important to improve utilization of coal.
Coal mill grinder or coal mill crusher is used to crush coal or to make coal in very small size. The coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove , 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm.
This picture a part of process in thermal power plant. The process is start from the coal inlet and introduce to the mill crusher. The end at the pulverized coal outlet.

Normally hydro plant doing major overhaul around 10 years for a cycle. Why we need such work to be carry out?
The main reason for setting up overhaul is to prevent unscheduled outages from failure of equipment. Since a machine which already run for a long period have lot of wear and tear and need to be treated well to make it last longer.
In order for the overhaul to proceed smoothly and to accomplish all the work required, planning should start well before the overhaul starts.
I am going to prepare roughly on what we have to do or prepare before we can carry out such a big job. Maybe it will takes some time to complete all the checklist. Anyway I will try to find out the data first before write an entry about hydro major overhaul.

DCS Vs SCADA
DCS is process oriented: it looks at the controlled process (the chemical plant or whatever) as the centre of the universe, and it presents data to operators as part of its job.
SCADA is data-gathering oriented: the control centre and operators are the centre of its universe. The remote equipment is merely there to collect the data--though it may also do some very complex process control!
A DCS operator station is normally intimately connected with its I/O (through local wiring, FieldBus, networks, etc.). When the DCS operator wants to see information he usually makes a request directly to the field I/O and gets a response. Field events can directly interrupt the system and advise the operator.
SCADA must operate reasonably when field communications have failed. The 'quality' of the data shown to the operator is an important facet of SCADA system operation. SCADA systems often provide special 'event' processing mechanisms to handle conditions that occur between data acquisition periods.

Pergau Water Intake at Kuala Yong Dam Hydroelectric dam on the Pergau River in Malaysia, near the Thai border. Building work began in 1991 with money from the UK foreign aid budget. Concurrently, the Malaysian government bought around £1 billion worth of arms from the UK. The suggested linkage of arms deals to aid became the subject of a UK government enquiry from March 1994. In November 1994 a High Court ruled as illegal British foreign secretary Douglas Hurd's allocation of £234 million towards the funding of the dam, on the grounds that it was not of economic or humanitarian benefit to the Malaysian people.

At last, I manage to purchase this Nokia C6-01 at Giant mall Kuala Terengganu. Earlier I said the price at Giant mall was only RM1099. Sorry to said that they make their mistake told me about the price before. I bought this one about Rm1180.
Instead of purchase of HTC Wildfire I think this Nokia C6-01 looks like more robust.
The package are as below:

I am going to Celcom Kota Bharu this morning since I have problem with my celcom simcard. The msg received 'sim error' always.
Celcom open their shop today at 09:30 to 12:30 only. Then I need to be there early morning to make sure that whatever it is, my phone can be used.
Saturday just nice... used this oppurtunity because weekdays now become more busy since we are at the end of the year....

Main inlet valve or shortly we say MIV is the spherical valve which installed before water enter into spiral casing of the hydro turbine.
Main inlet valve or MIV at hydro power plant.Water from the dam go to the penstock and before water enter the turbine, MIV is a component in between stop the water for small maintenance purpose in the turbine hall.

Vibrosystm Proximty ProbeHave you ever heard the brand call 'Vibrosystm'? I have never know this brand before but one of my friend told me that the brand is establish one if you comparing with the Bently Nevada.
Is there any body from Malaysia used this brand before? How about the support from Vibrosystm? Is there any local company here that given their service?
Anyway, will try first their product since the alternative (beside Bently Nevade) is more cheaper. And I am sure we need to suit with our budget first.
Even though still hesitate to use the Vibrosystm product, I would like to invite them, give oppurtunity for them to present how good the product they are.
