Interior protection: Interior protection is the general term for the installation of temporary dust and debris containment systems during re-roofing, remodeling, or other construction related projects.  A temporary interior protection system can be installed in almost any environment, from manufacturing plants, production facilities, class A office space, hospitals, schools or warehouses. Interior protection services include suspended ceilings, construction wall barriers, high structure cleaning and other types of custom applications.  Using reinforced engineered poly film and proven installation methods, temporary interior protection systems prevent re-roofing and remodeling dust and debris from cross contaminating clean room type environments within commercial facilities, retail stores, class A office space, and just about any type of environment you want kept clean.

Straßenbahnhaltestelle: Straßenbahnhaltestelle / Tramstop / Fermata del Tram, 1961–1976, A Monument to the Future (the complete title) is a work of installation art by the German artist Joseph Beuys.  Beuys originally created this installation for the German pavilion at the 37th Venice Biennale in 1976.  Today two copies of the work exist, one in the Kröller-Müller Museum, Otterlo, and another in the Hamburger Bahnhof, Berlin.  The work is based upon Beuys' childhood memories of a tram stop in Kleve on Nassauer Allee.  The installation consists of a long, rusty length of rail, four sections of broad, rusty pipe, and a cannon of the early modern type.  The cannon is topped by a cast iron head with a sorrowful expression.  These elements are laid parallel to one another on the ground.

The station ceased broadcast following the shutting down of the "Boston Phoenix" the previous week.

Skin cancer in horses: Skin cancer, or neoplasia, is the most common type of cancer diagnosed in horses, accounting for 45 to 80% of all cancers diagnosed.  Sarcoids are the most common type of skin neoplasm and are the most common type of cancer overall in horses.  Squamous-cell carcinoma is the second-most prevalent skin cancer, followed by melanoma.  Squamous-cell carcinoma and melanoma usually occur in horses greater than 9-years-old, while sarcoids commonly affect horses 3 to 6 years old.  Surgical biopsy is the method of choice for diagnosis of most equine skin cancers, but is contraindicated for cases of sarcoids.  Prognosis and treatment effectiveness varies based on type of cancer, degree of local tissue destruction, evidence of spread to other organs (metastasis) and location of the tumor.  Not all cancers metastasize and some can be cured or mitigated by surgical removal of the cancerous tissue or through use of chemotherapeutic drugs.

Engineering, procurement, and construction: "Engineering, Procurement, and Construction" (EPC) is a particular form of contracting arrangement used in some industries where the EPC Contractor is made responsible for all the activities from design, procurement, construction, to commissioning and handover of the project to the End-User or Owner.  This form of contract is covered by the FIDIC Silver Book containing the title words "EPC/Turnkey".  Other abbreviations used for this type of contract are "LSTK" for "Lump Sum Turn Key", "EPIC" for "Engineering, Procurement, Installation & Commissioning", and some times also "EPCC" which is short for "Engineering, Procurement, Construction and Commissioning".  Use of EPC is common e.g. by FIDIC and most Persian Gulf countries.  Use of LSTK is common in Kingdom of Saudi Arabia.  Use of EPCC is common in Qatar and some other countries e.g. by Qatar Petrolem.  Therefore, an EPC, LSTK or EPCC are all same types of contracts a typical well known example of which is the Silver Book of FIDIC.

Chris Welsby: Chris Welsby (born in 1948) is a British/Canadian experimental filmmaker, digital media and installation artist.  In the 1970s he was a member of the London Film-Makers' Co-op (now LUX film distributors), and co-founder of the Digital Media Studio (now Slade Centre for Electronic Media in Fine Art) at the Slade School of Fine Arts, UCL, London.  He is considered one of the pioneers of expanded cinema and moving image installation and was one of the first artists to exhibit film installations at the Tate and Hayward galleries London.  His expanded cinema works and installations have since continued to break new conceptual ground and attract critical attention.  A. L. Reece, in British Film Institute's "A History of Experimental Film and Video", wrote: "Twenty-five years ago, when he made his first projections for large spaces, film and art rarely met in the gallery; now it is common and installation art is a distinct practice."

WBCN (FM): WBCN is a digital-only radio station airing on WBZ-FM HD-2 in Boston, Massachusetts and owned by CBS Radio.  Before switching to 98.5 HD-2 on August 12, 2009, WBCN featured its rock format for 41 years as an analog radio station on 104.1 MHz (now WBMX).  WBCN became a legend in the rock music industry for breaking many bands, most notably U2.  WBCN was a modern rock/active rock station that mixed music that has been popular in the modern rock, alternative rock and classic rock genres.  Known as "The Rock of Boston", its three main Boston-area competitors as of 2009 were Album Oriented Rock/active rock WAAF and alternative music stations WBOS and WFNX.

Uterine cancer: Uterine cancer or womb cancer is any type of cancer that emerges from the tissue of the uterus.  It can refer to several types of cancer, with cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries.  Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from developed countries.  Risk factors depend on specific type, but obesity, older age, and human papillomavirus infection add the greatest risk of developing uterine cancer.  Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop.  If caught early, most types of uterine cancer can be cured using surgical or medical methods.  When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of chemotherapy, radiation therapy, or surgery may be required.

Optical attached cable: Optical attached cable (OPAC) is a type of fibre optic cable that is installed by being attached to a host conductor along overhead power lines.  The attachment system varies and can include wrapping, lashing or clipping the fibre optic cable to the host.  Installation is typically performed using a specialised piece of equipment that travels along the host conductor from pole to pole or tower to tower, wrapping, clipping or lashing the fibre optic cable in place.  Different manufacturers have different systems and the installation equipment, cable designs and hardware are not interchangeable.
