and vibration suppression Pollution

very efficiently transmitted through the generally stiff, metallic and therefore resonant structures. One common way of overcoming the considerable nuisance this can cause for the occupants is by absorbing the vibration and actually converting it to heat using viscoelastic polymer materials, typically based on polyurethanes or acrylics.
Over the past 20 years, Swedish Acoustic Products -- Swedac -- has built a track record in overcoming noise and vibration problems using this basic technology. Goran Falk, the company's technical director, claims it is possible to reduce noise levels by 50-70% with the right choice of materials and their effective application.
Although we have a range of standard products, the skill comes in knowing how best to use them. One also has to keep an open mind about modifying existing products or designing completely new solutions when the conditions require it, he says. Falk believes that sound and vibration suppression should be an integral element of the design of the structure as a whole and not an 'add-on'. For this reason, Swedac offers sound-damping engineering consultancy to ship and offshore platform designers and builders.
The company has supplied over 200,000 m2 of sound-damping deck coverings over the past 15 years. These generally consist of a trowel-applied liquid polymer, which, when dry, is overlaid with an SBR latex concrete. If speed of application is an issue, the liquid-applied polymer can be replaced with an adhesively-bonded polymer sheet.
Where the requirements are more stringent, for example, in laboratory areas, the company can offer a 'floating floor'. This comprises proprietary sound-damping PVP (plate/viscoelastic polymer/plate) laminate plates laid on top of 50mm of mineral wool (140-150 Kg/m3). The sound-damping plates, which were conceived by Swedac, consist of two layers of steel or aluminium, each 2 or 3 mm thick, separated by a thin layer of viscoelastic polymer.
While the performance of this type of system is impressive, even better sound and vibration suppression can be achieved, particularly at the lower frequencies commonly produced by engines, propellers, mud pumps and so on, by combining the floating floor with the company's standard viscoelastic polymer plus SBR latex concrete system (Figure 1). The measured insertion loss, ILv, expressed in dB for this system over a range of frequencies is shown in Figure 2.
Emtunga modules
Swedac has developed similar but thinner (2 mm total) and lighter PVP laminate plates for attaching to bulkheads to reduce noise transmission between cabins. Emtunga has used these extensively in the construction of accommodation modules.
In another variation on this theme, Swedac has supplied single steel sheets to Kvaerner with a layer of viscoelastic polymer that can be easily bonded to an existing steel surface. Kvaerner regularly uses this product on the plinths supporting water injection pumps on offshore platforms.
Recognizing that noise and vibration problems may only manifest themselves when structures have been completed and that older vessels may need to be upgraded, Swedac has also developed a cassette damping system for retro-fitting to bulkheads, vessel sides and beneath floors -- essentially anywhere in the noise path -- within ships and offshore platforms. These are simply a narrow steel trough containing viscoelastic polymer into which has been set a series of steel lugs to allow welding to the structure.
Swedac supplied its products and services widely in the offshore sector during the 1990s but suffered, like most suppliers, from the downturn towards the end of the decade. It switched its attention to the cruise ship market where it has

A Study of the Swimwear Industry in North America




Historical Timeline of the Bathing Suit
qThe North American Swimwear Market 4
qInfluential Factors of Demand5
qChanges in the Past Five Years18
qSunbathing-Related Health Concerns21
qIndependent Local Market Study23
The intent of this study is to become well informed of the North American swimwear industry, to discover opportunities that have not been exploited, and even try to determine where the industry is heading.  This information is very beneficial to one of our group members, Andree-Anne, who presently designs her own swimsuits and is very interested in opening a new type of retail store.  She sees a potential in creating swimwear that blends element of fashion and competition to extend its utility, durability, and comfort.  The new retail concept would also have a made-to-fit order policy to provide the best fit for every womans body type.  This industry study will hopefully give her greater insights and help bring these ideas to reality.    
We begin with the history of the swimsuit industry, followed by an extensive secondary data search.  This section contains the bulk of the factual findings, such as sales, demand factors, and channel conditions.  It includes a detailed analysis of the major competitors, how swimwear is branded, distribution channels, and promotional efforts.  This section gives an overview of all the internal and external factors and how they translate to the industrys strengths, weaknesses, opportunities, and threats.
A strategic analysis examines the past and current trends in the swimsuit industry, while the Future section examines research and development, obesity and the potential harm of UV exposure.
We then include all primary research, such as interviews with Yves Lepine, and an independent local market study.  
Finally, we conclude with recommendations and limitations of this study.
Historical Timeline of the Bathing Suit
300 B.C: First recorded use of bathing apparel was in Greece. Togas were worn when swimming and bathing reached the height of its popularity in the ancient world.  
During the 18th century men and women began to engage in public bathing in French and English spas, though a typical swim was very brief. Suits were cut to preserve modesty and resembled a "bathing gown." Theses first suits were far from practical or comfortable; ladies went as far as sewing lead weights into the hem of the "bathing gown" to prevent the dress from floating up and exposing her legs.
The first swimsuits consisted of bloomers and black stockings.  Around 1855, drawers were added to prevent the problem of exposure.  Women still refrained from swimming too much, as it was not generally accepted until the end of the 19th century, when swimming had become an intercollegiate and Olympic sport.
The beginning of the twentieth century marked a new daring era in swimwear for women. In 1907, Australian Annette Kellerman caused quite a stir, when she was arrested in the United States for wearing a loose, one piece suit that became the generally accepted swimsuit for women by 1910.  After that swimsuits began the trend of becoming lighter, briefer and more stylish. During the "Roaring 20's" an appreciation for recreation and leisure time was increasing dramatically. In May of 1916, the first annual "Bathing Suit Day" was held at Madison Square Garden in New York City.  Swimwear was now becoming skimpier, slimmer, sexier, and very athletic.
The 20th Century began the swimwear revolution, brought about by the major increase in recreational sports oriented activities and the influence of the exotic cuts of French swimwear.  
The 1930's lead to swimwear garments that were functional, sleek, and streamlined.  The 1934 swimsuit hugged the body and was constructed to allow shoulder straps to be lowered for tanning.  By the end of the decade, molded-fit suits were introduced, featuring the "nude look."   The "panel suit" was also popular, retaining a small skirt.
The 1940's had bathing beauties, pin-up girls, glamour girls wearing high heels, and jewelry to accessorize their bathing attire.  The most exciting was on July 5, 1946, designer Louis Reard introduced a 2-piece creation called the "bikini" at a fashion show in Paris.  The suit was named after a few small South Pacific islands called Bikini Atoll. It was proclaimed to be the smallest suit ever and helped comply with the war fabric rations.
In 1951, bikinis, perhaps seen as an ... more
