South Coast 25. The South Coast 25 is an American trailerable sailboat that was designed by Warren Metcalf as a cruiser and first built in 1969.

The boat was the first design effort by Metcalf, who was the son of the company owner, Hollis Metcalf. Warren Metcalf was killed in a diving accident just before completing the work on the design. His death was a factor in his father's sale of the company in 1975 and its subsequent closure in 1981.

Production
The design was built by South Coast Seacraft in United States, from 1969 until 1973. A total of 100 boats were completed, but it is now out of production.

The boat was available complete and ready-to-sail or as a kit for amateur completion. The time to complete the kit was estimated at 50–60 hours.

Design
The South Coast 25 is a recreational keelboat, built predominantly of fiberglass, with wooden trim. It has a masthead sloop rig, a self-bailing cockpit, a spooned raked stem, an angled transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel.

The boat is normally fitted with a small  outboard motor, mounted in a lazarette well, for docking and maneuvering.

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, a drop-down dinette table that forms a double berth on the port side of the main cabin and a quarter berth starboard aft. The galley is located on the starboard side just aft of the bow cabin. The galley is equipped with an icebox and a sink. There is also a small ice box in the lazarette's starboard side. The enclosed head is located just aft of the bow cabin on the port side. Cabin headroom is  or  with the cabin pop-top open. The fresh water tank has a capacity of .

The design has a PHRF racing average handicap of 231 and a hull speed of .

Operational history
The boat is supported by an active class club that organizes racing events, the South Coast Seacraft Owners' Association.

In a 2010 review Steve Henkel wrote, "best features: Headroom is an acceptable 5' 6", but with the poptop-type hatch in the elevated position, headroom increases to 6" 1", very good for a 25-footer. A supplemental ice chest in the stern quarter of the cockpit, presumably so the helmsperson doesn't have to bother the cook
to pass up a cool beverage, is a clever touch. Worst features: The bridge deck appears to be shallow enough
to permit water to pour down into the cabin if enough water from rain or waves sloshes into the cockpit."

Pierre Antoine Favre. Pierre Antoine Favre (; 20 February 1813 – 17 February 1880) was a French physician and chemist who specialized in conducting experiments in thermochemistry. In his work from 1852 along with Johann T. Silberman on heat produced by chemical reactions, he popularized the use of the unit "calorie".

Biography 
Favre was born in Lyons on February 20, 1813. He received a medical degree from Paris University in 1835. He shifted to study chemistry after being inspired by Jean Dumas' lectures and joined Eugene Peligot to study uranium salts. He was one of the two chemists who successfully demonstrated that the heats of the acid and bases were the sum of two constant terms, one dependent on the acid while the other on the bases. 

Favre then studied physiological chemistry under Louis Jecker, examining the composition of human sweat, forty litres of which he collected. One of his most important works was his investigation on the physiological chemistry of individuals who suffered from scorbutic complaints.

Favre took up a teaching position in chemistry. In 1843 he identified the atomic weight of zinc. His major contribution from 1844 to 1849 was in the measurement of heat evolved in chemical reactions. It has been claimed that he coined the term "calorie" although he only adopted the unit and made it more popular among French chemists. He is noted for his calometric studies of heat reactions, such as his examination of the heat of the reaction of gunpowder explosion. He joined the science faculty at Marseille in 1856 becoming dean in 1872 but retired in 1878 due to poor health.

Seismic classification in Italy. The seismic classification in Italy () is the subdivision of the territory of Italy into specific areas, characterized by a common seismic risk. Currently the seismic classification of the Italian territory into zones has remained exclusively for statistical and administrative aspects. With the legislation that came into force in 2009 (NTC08), after the earthquake that affected the city of L'Aquila, a new calculation methodology based on a point-like statistical approach is used for the purpose of anti-seismic design. Each point of the Italian territory is characterized by a precise ground acceleration value (Peak Ground Acceleration) as a function of a return time (ie a probabilistic value).

 Zone 1 : high seismicity (PGA over 0.25 g), includes 708 municipalities.
 Zone 2 : medium-high seismicity (PGA between 0.15 and 0.25 g), includes 2,345 municipalities (in Tuscany and Piedmont some municipalities are classified in Zone 3S, medium seismicity, which requires the calculation of the identical seismic action to Zone 2).
 Zone 3 : medium-low seismicity (PGA between 0.05 and 0.15 g), includes 1,560 municipalities.
 Zone 4 : low seismicity (PGA less than 0.05 g), includes 3,488 municipalities.

Antimicrobial nanotechnology. Antimicrobial nanotechnology is the study of using biofilms to disrupt a microbe's cell membrane, deliver an electric charge to the microbe, and cause immediate cellular death via a "mechanical kill" process, preventing the original microbe from mutating into a superbug. The biofilms are made up of long atomic chains that can breach the cell wall. These spikes are roughly the size of a human hair and are far too small to injure large cells in mammals. These atom chains have a significant positive charge that attracts bacteria that are negatively charged. A new class of antimicrobial has been created by applying nanotechnology to the challenge of superbugs and multiple drug resistance organisms.

Problem statement 

According to a report published in the Archives of Internal Medicine on 22 February 2010, health care–associated infections affect 1.7 million hospitalizations per year.

The most prevalent nosocomial infections can live or stay on surfaces for months, posing a continuing transmission risk. On dry surfaces, most gram-positive bacteria, including Enterococcus spp. (including VRE), Staphylococcus aureus (including MRSA), and Streptococcus pyogenes, can persist for months.

VRE has been cultured from frequently touched objects and has been found to survive on surfaces for more than three days. Dried cotton fabrics have been shown to support Enterococci that is resistant to vancomycin for up to 18 hours and fungi for more than five days.

Nanotechnology antimicrobials are promising because they limit the spread of bacteria by lowering the number of infection agents at frequent contact points (doorknobs, rails, tables, etc.). These new treatments have been certified by the Environmental Protection Agency and are being considered for use in hospitals and other settings where community-acquired illnesses spread quickly, such as cruise ships and jails. Environmental measures and adequate antibiotic use are the first steps in preventing the emergence of superbugs. According to studies, even if a patient does not need an antibiotic, a doctor is considerably more likely to prescribe one if they believe the patient does.

Safety and effects to the environment 

Antimicrobial nanotechnology is an environmentally friendly solution because it is based from water and contains no heavy metals, arsenic, tin, or polychlorinated phenols. According to tests, a garment treated with antimicrobial nanotechnology will degrade in a landfill in 5 years to carbon dioxide, nitrous oxide, and silicon dioxide.

Using a nanotechnology antimicrobial 

Biofilms are being developed as consumer products that can be sprayed or wiped over porous and nonporous surfaces. The microbe resistance of a surface treated with the appropriate antimicrobial nanotechnology can last up to 90 days, or the product's usable life, if protected during the production process.
On the preventative front, European researchers are developing MRSA-resistant nanotechnology-enhanced textiles that might be utilised in hospital gowns, curtains, bedding, and pillow coverings.
