Plastic Explosive

Plastic explosive

Plastic explosive is a soft and hand-moldable solid form of explosive material. Within the field of explosives engineering, plastic explosives are also known as putty explosives. Plastic explosives are especially suited for explosive demolition. Common plastic explosives include Semtex and C-4. The first manufactured plastic explosive was gelignite in 1875, invented by Alfred Nobel.

Cosmetic plastic surgery

While the majority of pediatric plastic surgery procedures done are reconstructive; there are those performed for cosmetic purposes. The most common procedures done for cosmetic benefit in children include: Breast augmentation Male breast reduction Ear surgery as a result of microtia RhinoplastyOut of all procedures, nose reshaping generally has the most cases on an annual basis (4,313 procedures in 1996). However, children make up only 9% of the total caseload for all nose reshaping. On the opposite end of the spectrum, children requiring ear surgery accounted for 2,470 procedures in 1996, a total of 34% of all total ear surgeries. While many of these procedures are done for purely cosmetic benefit, many plastic surgeons work on these features (giving them a more normal appearance), while performing a surgery to improve function as the result of a congenital deformity.

Plastic Little

Plastic Little (, Purasuchikku Ritoru) is a Japanese original video animation series created by Satoshi Urushihara. It was released in North America on VHS by ADV Films in July 1994. It was released on DVD in February 2002. Like much of Urushihara's work, Plastic Little provides significant amounts of fan service, and along with Burn-Up Excess, is one of two ADV titles to include the trademarked "Jiggle Counter". .

Silverstone (plastic)

SilverStone is a non-stick plastic coating made by DuPont. Released in 1976, this three-coat (primer/midcoat/topcoat) fluoropolymer system formulated with PTFE and PFA produces a more durable finish than Teflon coating. As of 1980 Dupont required that the pans carrying the brand be a heavier weight than others on the market. After the coating was applied the cookware was subsequently "baked" in a 700-800 degree oven to affix the coating. The process for creating Silverstone cookware begins by sandblasting the products which creates an uneven surface that encourages adherence. Then a primer layer of Teflon is sprayed on and after it is baked at high heat to "a secure mechanical grip." Gizmodo reported in 2014 that one or two more additional layers were applied after the initial layer.

Types of artificial plastic teeth

Types of artificial plastic teeth (known in the industry as Pontics) Wash-through Pontic (also known as hygienic pontic or sanitary pontic) Dome Pontic (also known as bullet or torpedo shaped) Ridge Lap Pontic (also known as Full Saddle Pontic) Modified Ridge-Lap Pontic Ovate PonticA pontic aims to restore aesthetics, give occlusal stability and improve function. Due to the poor aesthetics of this design it is most commonly employed to replace mandibular molars. Ridge lap and modified ridge lap pontics have superior aesthetics to the designs discussed previously, with the labial/buccal surface aiming to restore the appearance of a natural tooth from the incisal edge to the gingival margin. To minimise coverage of the soft tissues the lingual/palatal portion of the pontic is reduced to improve accessibility for maintaining good oral hygiene. It is commonly used in provisional bridges following extraction of teeth to improve the emergence profile and helps in shaping the gingiva around the future fixed prosthesis.

Hong Kong plastic shopping bag environmental levy scheme

The Hong Kong plastic shopping bag environmental levy scheme is an environmental levy scheme designed to reduce the manufacture and distribution of plastic shopping bags (PSBs) in Hong Kong. PSBs are made of materials that are not easily degradable. The extensive disposal of PSBs is putting stringent pressure on the very limited landfill capacity, thereby causing severe waste problems in Hong Kong. On 7 July 2009, the Government of Hong Kong initiated the first Mandatory Producer Responsibility Scheme (MPRS) under the Producer Product Eco-Responsibility Ordinance. Registered retailers are bound to charge consumers 50 cents as an environmental levy for each plastic bag taken. The levy scheme aims to generate direct economic disincentives and encourage consumers to refrain from using PSBs indiscriminately. The ultimate goal is to cultivate a habit of "Bring your Own Bag" (BYOB) within society. The full implementation of PSB charging came into effect on 1 April 2015. All retailers are required to collect not less than HK$0.50 for each plastic bag distributed. To streamline the compliance mechanism and enhance the deterrent effect, a fixed-penalty notice of HK$2,000 was imposed on retailers who fail to comply with the legislation.
