Dear All,

I am designing a sub-station for a 4 storeyed indutrial unit where I am proposing to install 2 nos. 1000kVA, 11kV/433V Dry Type Distribution Transformers on the roof top i.e. 5th floor. I propose to distribute power using sandwich type bus-bar trunking which will run from top to

Rotating Beam – Natural Frequencies

Hi,

does anybody know an analytical solution for the first two natural frequencies of a rotating beam (circular cross section) with end masses at both sides.

The rotating beam is suspended in two bearings with known stiffness, but these may be neglected at this moment and only

Exhaust Flue Gas – Duct Material

Hi! My design of Flue gas heat recovery system is complete. I am utilizing heat pipe stack to pre-heat the feed water using the heat from the exhaust flue gases of a boiler. The temp of flue gas at the entry of the system is at 230DegC. I am stuck with the selection of the material for the casing. C

Shealth Voltage Limiters and Zener Diodes

I'd like to know about Sheath Voltage Limiter. Suppose my system has 10 outgoing fdrs. Is it possible to use only one set SVL to protect all 10 fdrs? I like mean that all earth shunts of all cables will be connected to a common bus and that bus will be connected to earth bus via SVL.

Is it po

Dear Sir,

The mould temperature controller tries to keep the mould temperature constant depending upon the molten substance e.g. whether plastic, zinc or aluminium or their alloy being used. Assuming it is begining of the process when the mould temperature is assumed to be the ambient atmos

Ayn Randian blogger Pamela Geller endorses Chuck DeVore for US Senate in California GOP primary

From Eric Dondero:

Pamela Geller of Atlas Shrugs, a contributor to NewsMax and frequent guest on Fox News, has come out for libertarian-conservative Republican Chuck DeVore in the California primary for US Senate; the Barbara Boxer seat. Republicans Carly Fiorna and former Rep. Tom Campbell are also in the race. Campbell has come under fire recently for having once accepted a $500 contribution from a jailed Islamic Jihadist.

Wrote Geller in a blog post two days ago:

Forgive me for not talking up Chuck DeVore earlier. I have been watching him for awhile and I love him. He is going against that car alarm of a politician, Barbara Boxer, and RINO Carla Fiorina.

He is a tea party favorite and an Atlas favorite as well.

Geller was particularly impressed with Assemblyman DeVore's strong criticisms of Muslim students at UC-Irvine who recently tried to block a speech on campus by Israeli Ambassador Michael Oren. 11 Members of the Muslim Student Union were arrested. DeVore also criticized the group of supporting the terrorist organization Hamas, and actively fundraising for the organization.

Geller's previous endorsements include her longtime friend and ally Lt. Col. Allen West, an economic libertarian and staunch critic of radical Islam, running for Congress in Florida. DeVore, is also a Military Veteran, officer in the Army Reserves.

In the legislature DeVore has been a champion tax fighter and budget cutter, as well as a fierce opponent of nanny-state laws such as smoking bans and bans on trans fats.

Geert Wilders party PVV expected to make big gains in local elections

Campaigns for Dutch culture and against illegal immigration from the Middle East

The Hague is the second largest city in all of the Netherlands. The official royal home of the Dutch Queen, the city also serves as both the seat of the Dutch government and the provincal capitol. Additionally, The Hague serves as the judicial capitol for the United Nations.

The city population is 480,000. The metro area includes nearly 1.1 million inhabitants.

On March 3, the Dutch libertarian party (PVV - Party For Freedom) could become the second largest party in the municipality.

The Dutch News, Feb. 27:

The PVV is tipped to emerge as the biggest party in Almere and second biggest in the Hague.

Wilders was campaigning last week in Almere emphasizing pride in distinctly Dutch culture and strong opposition to Muslim women wearing the burqa in government buildings and at government-subsidized events.

Continuing:

'Almere must become the safest city in the Netherlands,' he said. 'There will be an end to subsidies for Turkish macramé and Arabic finger painting. Not just the Netherlands but all of Europe will look to Almere.'

Almere is a planned city in the central Netherlands with 184,000 residents. Both The Hague and Almere have been plagued by an influx of illegal immigration in recent years from Turkey and the Middle East.

NRC Report on NASA’s Suborbital Program

NRC Report: Revitalizing NASA's Suborbital Program: Advancing Science, Driving Innovation, and Developing Workforce

"The Space Studies Board (SSB) was requested by NASA to conduct a review of the suborbital mission capabilities of NASA in the NASA Authorization Act of 2008 (Section 505). The act expresses the sense of Congress that suborbital flight activities, including the use of sounding rockets, aircraft, and high-altitude balloons, and suborbital reusable launch vehicles, offer valuable opportunities to advance science, train the next generation of scientists and engineers, and provide opportunities for participants in the programs to acquire skills in systems engineering and systems integration that are critical to maintaining the nation's leadership in space programs. Further, the act finds it in the national interest to expand the size of NASA's suborbital research program and to consider it for increased funding."

Sprint Cuts Palm Pixi’s Price to $50 [PalmPixi]

Capitalism! Sprint was cool offering Palm Pixi for $100, until Verizon's Palm Pixi Plus slid in underneath at $79. Well Sprint's having none of that, slashing the original Palm Pixi's price to a mere $50 for new customers, after all of the rebates and contracts and what have you. Remember, the candybar Pixi doesn't have Wi-Fi and has a slightly smaller screen than the Pre, but if you or someone you know isn't quite ready for a big boy phone, a $50 Pixi could be hard to resist. Also remember, hard times ahead for Palm. [Sprint]


For Massachusetts, awaiting a decision by Bob Hedlund, but libertarian-conservative Jeff Perry jumps in

The southern Massachusetts Congressional seat of Democrat Rep. William Delahunt has been in the news, with yet another Kennedy making noises of a run - Robert Kennedy III, grandson of RFK - on the Democrat side. (AP article)

Longtime Libertaian Republican Bob Hedlund, is still weighing a run for the Congressional seat of the embattled representative.

From the Boston Herald, Feb. 3:

Hedlund, an 18-year senator and part-time radio host, said internal polls done by his campaign show him “within striking distance” of beating Delahunt in a head-to-head race. But the polling also shows a bruising battle in a three-way GOP primary against Perry (R-Sandwich) and former state Treasurer Joseph Malone, who is also weighing a run...

Meanwhile, Hedlund's friend and political ally in the Legislature has decided to jump in. Upon announcing State Rep. Jeffrey Perry said:

"They need someone who will stand up for the things they believe in and fight for action on issues like real health care reform without mandates, better job opportunities, checks on illegal immigration, national security, lower taxes and less national debt, and an end to the insider and special-interest dealing that permeates Capitol Hill. People across the South Shore, Cape Cod & the Islands are tired and frustrated with what they see as a system in Washington that’s broken and that’s incapable of progress on issues that matter to them. I want to be someone who changes that."

Perry is viewed as one of the two most conservative members of the Massachusetts Legislature. He's on record in favor of denying illegal immigrants state benefits that "cost Massachusetts legal residents millions of dollars every year."
