Cross-stitch is a form of sewing and a popular form of counted-thread embroidery in which X-shaped stitches in a tiled, raster-like pattern are used to form a picture. The stitcher counts the threads on a piece of evenweave fabric in each direction so that the stitches are of uniform size and appearance. This form of cross-stitch is also called counted cross-stitch in order to distinguish it from other forms of cross-stitch. Sometimes cross-stitch is done on designs printed on the fabric ; the stitcher simply stitches over the printed pattern. Cross-stitch is often executed on easily countable fabric called aida cloth whose weave creates a plainly visible grid of squares with holes for the needle at each corner.
Embroidery is the craft of decorating fabric or other materials using a needle to apply thread or yarn. Embroidery may also incorporate other materials such as pearls, beads, quills, and sequins. In modern days, embroidery is usually seen on caps, hats, coats, overlays, blankets, dress shirts, denim, dresses, stockings, and golf shirts. Embroidery is available in a wide variety of thread or yarn colour.
Knitting is a method by which yarn is manipulated to create a textile, or fabric. It is used to create many types of garments. Knitting may be done by hand or by machine.
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift.
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry.
Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft – examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period. Handmade chain stitch embroidery does not require that the needle pass through more than one layer of fabric. For this reason the stitch is an effective surface embellishment near seams on finished fabric. Because chain stitches can form flowing, curved lines, they are used in many surface embroidery styles that mimic "drawing" in thread.
Storm Shadow is an Anglo-French low-observable, long-range, air-launched cruise missile developed since 1994 by Matra and British Aerospace, and now manufactured by MBDA. Storm Shadow is the weapon's British appellation. In French service, it is called SCALP-EG. The missile is based on the French-developed Apache anti-runway cruise missile. They differ in that the Storm Shadow carries a warhead instead of submunitions.
The AGM-154 Joint Standoff Weapon (JSOW) is a glide bomb that resulted from a joint venture between the United States Navy and Air Force to deploy a standardized medium range precision guided weapon, especially for engagement of defended targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimizing friendly losses. The designation of the Joint Standoff Weapon as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the older GBU-15.
In everyday language, a stitch in the context of embroidery or hand-sewing is defined as the movement of the embroidery needle from the back of the fibre to the front side and back to the back side. The thread stroke on the front side produced by this is also called stitch. In the context of embroidery, an embroidery stitch means one or more stitches that are always executed in the same way, forming a figure. Embroidery stitches are also called stitches for short.
A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole to hold the sewing thread. The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance. High quality embroidery needles are plated with two-thirds platinum and one-third titanium alloy. Traditionally, needles have been kept in needle books or needlecases which have become objects of adornment. Sewing needles may also be kept in an étui, a small box that held needles and other items such as scissors, pencils and tweezers.
The Aero L-29 Delfín is a military jet trainer developed and manufactured by Czechoslovakian aviation manufacturer Aero Vodochody. It is the country's first locally designed and constructed jet aircraft, as well as likely being the biggest aircraft industrial programme to take place in any of the Council for Mutual Economic Assistance (COMECON) countries except the Soviet Union.
The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low to intermediate-yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design. It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law.
Embroidery in India includes dozens of embroidery styles that vary by region and clothing styles. Designs in Indian embroidery are formed on the basis of the texture and the design of the fabric and the stitch. The dot and the alternate dot, the circle, the square, the triangle, and permutations and combinations of these constitute the design.
Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric; i.e., following adjacent columns, or wales, of knitting, rather than a single row, or course. For comparison, knitting across the width of the fabric is called weft knitting.
Double knitting is a form of hand knitting in which two fabrics are knitted simultaneously on one pair of needles. The fabrics may be inseparable, as in interlock knitted fabrics, or they can simply be two unconnected fabrics. In principle, an arbitrary number of fabrics can be knitted simultaneously on one pair of knitting needles with yarns, as long as one is careful.
Bead embroidery is a type of beadwork that uses a needle and thread to stitch beads to a surface of fabric, suede, or leather.

The Armed Forces of the Philippines (AFP) Modernization Act, officially designated as Republic Act No. 7898, was a Philippine law that was enacted on February 23, 1995, by President Fidel V. Ramos. It was aimed to modernize all branches of the Armed Forces of the Philippines (AFP) such as the Philippine Air Force, Philippine Navy, and the Philippine Army. The law was intended to last for 15 years with an initial budget of 50 billion pesos for the first five years, but the funding was stopped due to the 1997 Asian financial crisis. After the financial crisis, the funding for the AFP modernization was halted and later neglected by successive administrations until the law expired in 2010.
