David Dunlap (lobbyist). David Dunlap is an American lobbyist, and chemical engineer.

Life 
He graduated from Virginia Tech.

He was director of Policy and Regulatory Affairs with Koch Industries.

In 2018, he joined the Environmental Protection Agency, Office of Research and Development. He was involved in the EPA's assessment of the health impacts of formaldehyde, a chemical produced by the Koch Industries. Despite having received the recusal statement from the EPA's Ethics Law Office on October 30, Dunlap signed it on December 19, the same day as the EPA blocked the assessment that warned of the carcinogenic and other medical risks linked to formaldehyde. He notably participated in email discussions regarding the assessment at least twice after he agreed to recuse himself and before he officially signed the statement.

He is vice-president of Global Government Relations at Harsco.

Schneider Euro PC. The Schneider Euro PC was a PC compatible home computer, introduced in 1988 by the Schneider Computer Division.

A follow-up to the success of the Schneider CPC series, the Euro PC offered an inexpensive entry into the emerging market for home PCs. The computer used a Siemens 8088 processor (clocked at 4.77, 7.15 or 9.54 MHz according to a BIOS setting or key combination), had 512 KB of RAM (expandable to 640 KB), and was shipped with MS-DOS 3.3 and Microsoft Works 1.0.

As with many other home computers of its time, the computer circuit board was built into the keyboard housing. A 12" amber monochrome monitor (MM12) and a 14" color monitor (CM14) were available for the system. The Euro PC had a graphics chip that could be switched between monochrome Hercules and color CGA modes. The power supply was external, an unusual feature for a PC.

A 3-inch floppy disk drive (720 KB) was installed as a mass storage device. An external 3-inch floppy disk drive with 720 KB (FD720), a 5-inch floppy disk drive with 360 KB (FD360), and a 20 MB hard disk (XT Attachment, similar to IDE / ATA ) were available as accessories. This could not be replaced by any other model, as the drive parameters were permanently programmed into the BIOS. However, it was possible to operate other hard drives with a corresponding controller in the expansion slot.

The computer was sold through large mail-order companies at a price of 1,800 DEM. The highly competitive PC market left little room for new machines, but the Euro PC was still sold in considerable numbers thanks to its very low price and slim, home computer-like appearance.

An updated version, the Euro PC II introduced in 1989, had 768 KB RAM and a 8087 mathematical coprocessor. Another version with further expansions was called EURO XT.
The Euro AT offered a 80286 processor, 1 MB of RAM, and a EGA graphics card. The Euro SX, introduced in 1992, came with a 80386SX processor.

Scherbius Drive. The Static Scherbius Drive provides the speed control of a wound rotor motor below synchronous speed. The portion of rotor AC power is converted into DC by a diode bridge. This motor drive has the ability of flow the power both in the positive as well as the negative direction of the injected voltage.

The Scherbius Drive is an electrical drive system invented by Arthur Scherbius, a German engineer known for his work in electrical engineering and cryptography (he also invented the Enigma machine). This drive system is primarily associated with controlling the speed of electric motors, particularly asynchronous (induction) motors. It is closely related to the static Kramer drive.

Key Features

Slip Power Recovery
The drive enables the recovery and reuse of slip power from the rotor circuit of a wound-rotor induction motor. Instead of wasting the slip power as heat, it redirects it back to the power supply or another part of the system, improving overall efficiency.

Use of Rotary Converters
In its original design, Scherbius Drive used rotary converters (essentially motor-generator sets) to modulate the slip power. Modern implementations often replace rotary converters with solid-state electronics like inverters.

Variable Speed Control
By managing the slip power, the Scherbius Drive allows for speed control of the motor. This makes it particularly useful in applications requiring variable-speed operation, such as cranes, wind turbines, and pumps.

Advantages
Improved efficiency due to slip power recovery.
Smooth and reliable speed control.
Suitable for high-power industrial applications.

Modern Evolution
Modern systems inspired by the Scherbius Drive concept now use advanced power electronics, such as static Scherbius drives, which incorporate converters and inverters to perform the same function with higher efficiency and flexibility.

Transit 380. The Transit 380, styled as the Transit_380 or T_380, is an American sailing dinghy that was designed by Jim Taylor for youth sail training and first built in 2005. The boat was intended to act as a "transition" boat between the Optimist dinghy and more high performance boats. The designation indicates the length overall in centimeters.

Production
The design was built by Precision Boat Works in Palmetto, Florida, United States starting in 2005, but it is now out of production.

Design
The designer notes, "The T_380 design ... is intended to suit young sailors who are making the transition from the single-handed Optimist pram to high performance double-handed dinghies. Most kids 'size out' of the Opti at about 115 pounds, and between the ages of 11 to 14. After years of sailing alone in prams, many are also looking forward to sailing together with friends. Many do not yet have the sailing skills and experience required to handle a Club 420, however, and expecting them to do so is a bit like handing a new driver the keys to a Porsche. For decades, the Blue Jay and Widgeon (among others) have filled this gap, but time and technology have long since passed these boats by. The Transit_380 brings modern materials and carefully 'kid centered' design detailing to a contemporary version of this transitional mid boat."

The Transit 380 is a recreational sailboat, built predominantly of hand-laid fiberglass, with aluminum spars. It has a fractional sloop rig, a nearly-plumb stem, an open reverse transom, a transom-hung composite rudder controlled by a tiller and a retractable centerboard. It displaces  and has foam flotation, making it unsinkable.

The boat has a draft of  with the centerboard extended and  with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer.

For sailing downwind the design may be equipped with a symmetrical  spinnaker.

Operational history
In a 2006 review for Sail magazine Jim Springer wrote, "it's a stable two-person dinghy designed for the 11-to-15-year-old 'in-betweens' who don't fit in Optis anymore and aren't quite ready for prime time. It does have a racy planing hull and asymmetric spinnaker to keep young speed demons enthused. The rig is small enough to minimize capsizes, but if the boat does go over, the watertight mast and extra flotation on the mainsail head will help keep it from turtling. Once the boat is righted, the self-bailing cockpit drains quickly through the open transom. Precision Boatworks. "

Train v. Natural Resources Defense Council, Inc.. Train v. Natural Resources Defense Council, 421 U.S. 60 (1975), is a United States Supreme Court case in which the Court held that the EPA must approve a State Implementation Plan if it meets the criteria under the Clean Air Act.

Facts
The 1970 amendments to the Clean Air Act required states to meet federally mandated air quality standards within a statutorily specified period of time. States were directed to submit to the Administrator of the EPA a plan to "implement, attain and maintain" the federally adopted standards within nine months of the promulgation of such standards. The EPA Administrator was required to approve implementation plans meeting the statutory criteria and to promulgate substitutes for those found deficient. A number of states included variance procedures in their implementation plans, which the EPA approved. The NRDC challenged the EPA's approval of Georgia's implementation plan on the grounds that the postponement provision of the Clean Air Act was the only method to modify the state implementation plans. The Fifth Circuit Court of Appeals held that the Georgia plan should not have been approved, and the Supreme Court granted certiorari.

Opinion 
In an opinion delivered by Justice Rehnquist, the Court concluded that the Fifth Circuit erred in holding that postponements were
the exclusive means by which individual sources could obtain relief from state implementation plans. The Court held that the Fifth Circuit had improperly substituted their judgment for the agency's judgment, and the flexibility in the language of the Clean Air Act left the states with the requisite authority to grant source-specific variances. The Court further held that as long as the "ultimate effect of a State's choice of emission limitations is compliance with the national standards for ambient air," a state is "at liberty to adopt whatever mix of emission limitations it deems best suited to its particular situation."

Cua Dai Bridge. Cua Dai Bridge (), is a cable-stayed bridge that crosses the Thu Bồn River in Quang Nam Province, Vietnam.

Construction
In June 2009, a VND2 trillion (US$111 million) infrastructure budget was approved, which included resources allocated for the Cua Dai Bridge project.  In August 2009, a groundbreaking ceremony marked the start of construction on the bridge.  

Cua Dai was built using the balanced cantilever method made with concrete spans. The structure consists of prestressed reinforced concrete and reinforced concrete. At 150 meters, it has the longest cantilever span in Vietnam. The bridge is the longest in Quang Nam Province. By the completion of construction, the project would cost 3,450 billion VND.  Cua Dai bridge was built as part of a larger  road project, which includes the  kilometer road from Hoi An, a  kilometer roads from Duy Xuyen District, and the   of the bridge itself.

Operation
In 2016, the bridge was open for traffic on a trial basis, establishing a direct route in Hoi An between Duy Xuyên and Thăng Bình districts.   Previous to the bridge's construction, local commuters were required to use the distant Tra Khuc II Bridge or embark on small boats to cross the wide Thu Bon River. Officials estimate that despite the districts being only 2km apart as the crow flies, motorists would travel 20 kilometers of distance by using the Tra Khuc II Bridge.  The bridge has an expected lifespan of 100 years. 

The bridge also serves as a major connection within a coastal road project that would go through North, Central, and Southern regions of Vietnam. The bridge expanded the maritime capacity of the provinces within Vietnam's Central region, including an expansion of Kỳ Hà Port.   In addition to reducing daily traveling time, the bridge is also serves a role in preventing storms and floods, aiding with emergency evacuation, and connecting the banks of the world heritage sites of Old Town Hội An and the Mỹ Sơn temple complex.
