Graping. Graping is a phenomenon marked by the appearance of unreflowed solder particles on top of the solder mass. The solder that is partially coalesced resembles a cluster of grapes, hence the derivation of the phenomenon’s name.

Causes 
Graping occurrence has continued to increase since it was first identified in 2006. The viscosity of the flux decreases as the temperature of the reflow oven increases. Lead-free reflow soldering temperatures are higher, which results in more graping. Graping is also caused by increased surface oxidation. The increased surface oxidation is the result of smaller printed paste deposit volumes that cause a diminished surface area to flux ratio of the solder particle, resulting in flux exhaustion. While solder paste can be manufactured using any size range, there has been a move towards finer particle sizes, especially for fine feature stencil printing. Finer particle sizes places added pressure on the solder paste flux to remove surface oxides, which leaves the outside of the joint not fully coalesced, producing the irregular surface finish known as graping.

Resolutions 
The graping phenomenon can be resolved utilizing proper solder materials in addition to correct reflow profile settings. Solder powders are available that provide a tighter distribution range as well as a high oxidation barrier. This barrier not only improves the paste release from the stencil, but also provides an ideal surface area-to-volume ratio. These solder powder characteristics help to eliminate the graping phenomenon. Future solder paste flux formulations provide sufficient activity paired with re-oxidation mitigation capabilities. This pairing means that graping can be resolved as it occurs, which is ideal for miniaturization processes.

There are also steps to take when setting up one's reflow profile to reduce the amount of heat exposure to the solder paste during the reflow process and prevent graping:
 
 Opt for a ramp to peak profile, as opposed to a soak profile.
 Adjust the belt speed to decrease the total time in oven to a recommended ramp rate of 1 °C/second from ambient to peak.
 Utilize a peak temperature ranging from 235°-240 °C.
 Cut back the time above liquidus (TAL) to 40–60 seconds.

Raj Hamsa X-Air. The Raj Hamsa X-Air is an Indian, two-seat, high-wing, tricycle gear, tractor configuration, ultralight aircraft produced by Raj Hamsa Ultralights of Bangalore, Karnataka in kit form, for amateur construction.

Design and development
The X-Air started as a development of the Chotia Weedhopper redesigned to incorporate ailerons and an enclosed cabin. After initial production in Europe manufacturing was shifted to Raj Hamsa in India. In many countries the aircraft is known as the Rand Kar X-Air. In the USA it is sometimes referred to as the Light Wing X-Air. The aircraft was later developed into the more conventional X-Air Hanuman, which relocated the engine from the upper keel tube to the nose.

The X-Air is built from bolted aluminium tubing, mated to a central welded steel cockpit cage. The wings and tail surfaces are covered in pre-sewn Dacron sailcloth envelopes. The aircraft is built around its keel, a large tube that runs from the high-mounted engine in the front to the tail in the back. The wings are supported by V-struts with jury struts. The landing gear incorporates oleo shock absorbers on all three wheels. The nosewheel is steerable and mainwheel brakes are standard. Dual controls are standard, but cockpit doors are optional. The cockpit has been criticized by reviewer Andre Cliche as "a bit difficult to access".

The X-Air can be fitted with either floats or skis. Engines from  can be fitted, provided they weigh under . The construction time is estimated at 40 hours.

Operational history
Due to its low price and BCAR Section "S" certification the X-Air has proven popular in the United Kingdom.

An X-Air has been used as a testbed for the prototype D-Motor LF26 flathead engine.

Variants

Jockey box. A jockey box is an insulated container containing ice and water, as well as a long coil of hollow tubing. The device is used to cool beverages being served on tap in temporary locations.

One end of the coiled tube in the box is fitted to the external supply of the beverage to be served (often moved from the supply container by gas pressure, as in the case of beer in kegs, and the other end is attached to taps for serving the beverage, which are often integrated into the box itself. Filling the jockey box with ice and water cools the coiled tubing, and when the beverage flows through the tube, the beverage is cooled to a temperature just above freezing, even if it was at room temperature before it entered the box. This allows cold drinks to be served on tap in temporary and outdoor venues.

Apart from the coil and taps, the jockey box resembles a cool box. Some jockey boxes force the liquid through a solid cold plate rather than a coil of tubing (see Alternative Portable Cooler Dispensers below).

A glove compartment is also sometimes referred to as a "jockey box," especially in the U.S. Upper Rocky Mountain states.

For the prior-to-use cleaning, use a flush-out hose to remove any residue or mold that might have built up inside the lines since the last time you used the jockey box.

Alternative Portable Cooler Dispensers

In the coil cooler, a stainless steel coil is covered with water and ice, in which the liquid is made to run through. At the contact with the cold coil, the beverage becomes cold.  
On the flip side, the cold plate works making the beverage run across an ice covered aluminum cold plate. When the plate makes contact with the ice, the plate become cold provoking the liquid that runs over it becomes cold too.

A portable ice maker and water dispenser is a device that produces ice, and release chill water by a small in-house generator. Depending on the size, some of them require a water line connection, but most of them only needs to have water deposited in its container.

Curtiss Model 41 Lark. The Curtiss Model 41 Lark was a commercial biplane manufactured by Curtiss Aeroplane and Motor Company that was used by pioneering airmail, airline and bush pilots in the 1920s.

Development

The biplane was based on the Curtiss Carrier Pigeon, a purpose-built aircraft for airmail operations. The Lark also had a longer-span lower wing, similar to the Carrier Pigeon. Some models were converted to floatplane configuration with a central mounted pontoon and wing-mounted floats.

The biplane was made of welded tube with fabric covering. It was available with three engine choices, the Curtiss C-6, the Wright J-4 Whirlwind, and the Wright-Hisso E. All four wing panels were interchangeable, giving the aircraft its unusual longer lower wings.

A 200 hp Wright J-4 variant was tested for the United States Navy. This installation proved superior in performance to the Curtiss engined model. This version eventually became the basis for the Curtiss Fledgling series of aircraft.

Operational history

Patrica Airways operated a Lark for early bushplane operations. The aircraft flew with floats in warm weather, and skis in the winter. The aircraft was pressed into service as an early hearse once, with the cargo needing to be seated upside down in the open seat and secured with haywire.

Florida Airways operated a Curtiss Lark Miss Tallahassee on its CAM-10 U.S. airmail route between Miami and Atlanta. The aircraft was bought to take the place of two lost Stout 2-AT Pullman aircraft that could not operate out of the poorly prepared airstrips.

Colonial Air Transport owned a Curtiss Lark which was one of the first aircraft to be registered using the new Underwriters Laboratories all-letter system (1921 to 1923). This Lark, registered as N-AABC, was used on the CAM-1 U.S. airmail route.

Cyber City Kochi. Cyber City, Kochi, also known as Adani Cyber City, is a proposed Special Economic Zone information technology park in the city of Kochi, Kerala, India. It is promoted by Adani and is located near HMT at Kalamassery. The SEZ will be built over a land area of . Construction was expected to start on 17 February 2011, and the first phase was scheduled to be within two years. The current status of the project is uncertain as the work never commenced as planned.

According to the rules governing a Special Economic Zone, 70% of the built-up area will be processing area for IT and ITES business, primarily for export. The remaining 30 per cent is categorised as a non-processing zone and will feature shopping malls, convention centres, apartment complexes and other lifestyle needs, developing it into a full-fledged township.

The first phase consists of a built-up space of , to be built in two years. Once completed, it will house a built-up space of .

Location & Connectivity

The planned township is on 70 acres of land bought from HMT. It is located 17 km from the city centre and 22 km from the International Airport, among an area where a number of other similar developments are being planned. the distance to NH 47 is 5 km.

The VSNL’s communication gateway is located less than 7 km from the park. This gateway handles around 70% of the country’s data traffic. The proximity to the SAFE and SEA-ME-WE 3 cables dropping zone and direct optical fibre link to the gigabyte router of VSNL, enables the park to offer 100% uptime data connectivity to units. Kochi offers Pacific and Atlantic route of connectivity to the US.

Infrastructure

70% of the built up area of the township will be used for IT and ITES industries. The remaining 30% will be non processing area, used for residential, commercial and entertainment purposes.

Navalised aircraft. A navalised aircraft (or navalized aircraft) is an aircraft that has been specifically designed for naval use, in some cases as a variant of a land-based design. An aircraft based on an aircraft carrier is called carrier-based aircraft.

Characteristics
A navalised aircraft typically differs from its land-based equivalent by:

 The airframe, engine and avionics are marinised against salt water corrosion.
 It is designed to be used on a flight deck. For a fixed wing aircraft this typically means catapult attachment points, a tailhook and strengthened undercarriage. Naval helicopters usually have wheels rather than skids and may have mechanisms to attach to the deck.
 It is designed to occupy minimum hangar space – for example the wings, tail-boom or rotors may fold.
 There is enhanced protection against water ingress (including that from hosing down with fresh water to get rid of salt water).
 Equipment such as sensors and weapons are optimised for naval roles.
 The avionics is compatible with the complex electronic equipment of a warship, and that there is no electromagnetic interference between the two.
 There is provision for ditching at sea.
 Helicopters may have provision for receiving fuel through the cabin while hovering adjacent to a ship.

For safety reasons, the aviation fuel provided by ships may be different (e.g. AVCAT) from that provided by airfields and tanker aircraft.

Examples
The T-45 Goshawk is a navalised version of the BAE Hawk jet trainer. Differences from the Hawk include changes to the undercarriage for aircraft carrier compatibility and a strengthened airframe. The engine design was also modified for the aircraft's role at sea. A proposed navalised version of the Alpha Jet would have had similar design modifications.

Other examples of navalised variants of land-based aircraft include:
 Bell AH-1 SuperCobra
 British Aerospace Sea Harrier
 Dassault Rafale M
 HAL Tejas Naval
 Hawker Sea Fury
 Hawker Sea Hurricane
 Lockheed Martin F-35C Lightning II
 Mikoyan MiG-29K
