Waist (other)
Waist is the narrow point of the body between the ribcage and hips. Other meanings derive from this by extension. * Waist (clothing) is also a term for the bodice of a dress or for a blouse or woman's shirt. * Waist, a variant of waistline, the line of demarcation between the upper and lower portions of a garment, which notionally corresponds to the natural waist but may vary with fashion from just below the bust to the upper hips * Waist, the narrowest part of a laser beam, see Gaussian beam In optics, a Gaussian beam is a beam of electromagnetic radiation with high monochromaticity whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile.

Waist
The waist is the part of the abdomen between the rib cage and hips. On people with slim bodies, the waist is the narrowest part of the torso. ''Waistline'' refers to the horizontal line where the waist is narrowest, or to the general appearance of the waist. Structure Because of this and because the waist is often synonymous with the stomach, one can become confused as to the exact location of the waist. Another confusing factor is that the waistline differs on different people. A study showed that self-reported measurements as opposed to measurement done by a technician, underestimated waist circumference and this underestimation increased with increased body size. In the study, waist circumference measured at the level of the umbilicus was larger than that measured at the natural waist. To locate the natural waistline, one need simply stand upright and then tilt over to the side keeping the legs and hips straight. Where the torso creases is the natural waistline. Waist me ...

Ribcage
The rib cage, as an enclosure that comprises the ribs, vertebral column and sternum in the thorax of most vertebrates, protects vital organs such as the heart, lungs and great vessels. The sternum, together known as the thoracic cage, is a semi-rigid bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton. A typical human thoracic cage consists of 12 pairs of ribs and the adjoining costal cartilages, the sternum (along with the manubrium and xiphoid process), and the 12 thoracic vertebrae articulating with the ribs. Together with the skin and associated fascia and muscles, the thoracic cage makes up the thoracic wall and provides attachments for extrinsic skeletal muscles of the neck, upper limbs, upper abdomen and back. The rib cage intrinsically holds the muscles of respiration ( diaphragm, intercostal muscles, etc.) that are crucial for active inhalation and forced exhalation, and the ...

Waist (clothing)
From the early 19th century through the Edwardian period, the word ''waist'' was a term common in the United States for the bodice of a dress or for a blouse or woman's shirt. A shirtwaist was originally a separate blouse constructed like a shirt; i.e., of shirting fabric with turnover collar and cuffs and a front button closure. In the later Victorian period, the term became applied more generally to unlined blouses with relatively simple construction and usually of a cotton or linen fabric, but often highly ornamented with embroidery and lace. From the mid-20th century, the term ''shirtwaist'' referred to a dress with the upper portion (the bodice and sleeves) fashioned like a man's shirt, with a turnover collar (clothing), collar and Button (clothing), buttons down the front. Different embroidery were added to the shirtwaist, like rhinestones and different patterns. Women who entered the workforce often wore this style of garment, and it was thus seen as a symbol of the 'New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waistline (clothing)
The waistline is the line of demarcation between the upper and lower portions of a garment, which notionally corresponds to the natural waist but may vary with fashion from just below the bust to below the hips. The waistline of a garment is often used to accentuate different features. The waistline is also important as a boundary at which shaping darts (such as those over the bust and in the back) can be ended. Types of waistlines Similar to necklines, waistlines may be grouped by their shape, depth, and location of the body. * None: The princess seams style of dress needs no waistline at all, since it does its shaping without darts, by joining edges of different curvature. The resulting "princess seams" typically run vertically from the shoulder (or under the arm) over the bust point and down to the lower hem. This creates a long, slimming look, often seen in dresses with an " A-line" silhouette. * Diagonal: An asymmetrical waistline that runs across the body diagonally. Usual ...

Gaussian Beam
In optics, a Gaussian beam is a beam of electromagnetic radiation with high monochromaticity whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile. This fundamental (or TEM00) transverse Gaussian mode describes the intended output of most (but not all) lasers, as such a beam can be focused into the most concentrated spot. When such a beam is refocused by a lens, the transverse ''phase'' dependence is altered; this results in a ''different'' Gaussian beam. The electric and magnetic field amplitude profiles along any such circular Gaussian beam (for a given wavelength and polarization) are determined by a single parameter: the so-called waist . At any position relative to the waist (focus) along a beam having a specified , the field amplitudes and phases are thereby determinedSvelto, pp. 153–5. as detailed below. The equations below assume a beam with a circular cross-section at all va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
