Mercuric amidochloride. Mercuric amidochloride is an inorganic compound with the formula .

Preparation and properties
It arises from the reaction of mercury(II) chloride and ammonia (Calomel reaction), where the resulting mercuric amidochloride is highly insoluble.

It forms white crystals in the shape of small prisms.  It tastes earthy and metallic, but is a deadly poison and should not be ingested.

At the molecular level, it organizes as a zig-zag 1-dimensional polymer  with chloride counterions.

It is stable in air, but darkens on exposure to light. It does not melt, even at dull red heat, instead subliming and decomposing to gaseous mercury, hydrogen chloride, and nitrogen oxides.  Consequently sealed containers with this chemical may explode when heated.

The substance is a deadly poison, although not a carcinogen. It is toxic unto lethality by inhalation, ingestion or dermal absorption.  In lesser cases, it may instead cause dermatitis and skin lesions or corrode the mucous membranes. If improperly handled, it may cause dangerous environmental pollution, in soil, water bodies, and air.

Addition of base converts it into "Millon's base", named after Eugène Millon, which has the formula . A variety of related amido and nitrido materials with chloride, bromide, and hydroxide are known.

Uses
Before the toxicity of mercury was revealed, mercuric amidochloride, then known as "ammoniated mercury" or "white precipitate", was used as a topical skin antiseptic, especially for impetigo, dermatomycosis and other certain dermatoses. It was also used for scaling in psoriasis, to treat pruritus ani, and against pinworm and ringworm infection (especially in dogs), against crab louse infestation, against lesions on the body and near eyes, against bumblefoot infection on poultry, and as a disinfectant. Chronic use of this medication can lead to systemic mercury poisoning. Since less toxic medications are available now, to treat those conditions, there is no need to use mercuric amidochloride as a medication anymore.

Cambridge Crystallographic Data Centre. The Cambridge Crystallographic Data Centre (CCDC) is a non-profit organisation based in Cambridge, England. Its primary activity is the compilation and maintenance of the Cambridge Structural Database, a database of small molecule crystal structures. They also perform analysis on the database for the benefit of the scientific community, and write and distribute computer software to allow others to do the same.

History 
In 1962, Dr. Olga Kennard OBE FRS set up a chemical crystallography group within the Department of Chemistry, University of Cambridge. In 1965 she founded the CCDC and established the associated Cambridge Structural Database. At that time, there were only about 3,000 published X-ray structures, and the work involved converting these into a machine-readable form. Kennard invited Frank Allen to join the group, which he did in 1970, becoming Scientific Director and then Executive Director before retiring in 2008.

In 1992, the CCDC moved into its own building adjacent to the Cambridge chemistry department. This new headquarters was designed by the Danish architect Professor Erik Christian Sørensen and won The Sunday Times Building of the Year Award in 1993.

The CCDC still retains very close links as a University Partner Institution that trains students for postgraduate research degrees but from 1987 became an independent company. By 2019 the database had grown to over a million structures.

Current research 

The staff at the CCDC curate the database of small-molecule organic and metal-organic crystal structures and make these available for download by the public. They also create and maintain a suite of cheminformatics software that may be used to apply the data to applications in the life sciences, including crystal engineering and materials science.

Programs Developed 
CCDC developed programs such as ConQuest and Mercury that run under Windows and various types of Unix, including Linux. ConQuest is a search interface to the Cambridge Structural Database (CSD). Mercury is a crystal structure visualizer tool, of which later versions released in 2015 and later provide the functionality to generate 3D prints.

Trimethylsilanol. Trimethylsilanol (TMS) is an organosilicon compound with the formula (CH3)3SiOH.  The Si centre bears three methyl groups and one hydroxyl group. It is a colourless volatile liquid.

Occurrence
TMS is a contaminant in the atmospheres of spacecraft, where it arises from the degradation of silicone-based materials. Specifically, it is the volatile product from the hydrolysis of polydimethylsiloxane, which are generally terminated with trimethylsilyl groups:
(CH3)3SiO[Si(CH3)2O]nR  + H2O  →  (CH3)3SiOH  +  HO[Si(CH3)2O]nR

TMS and related volatile siloxanes are formed by hydrolysis of silicones-based containing materials, which are found in detergents and cosmetic products.

Traces of trimethylsilanol, together with other volatile siloxanes, are present in biogas and landfill gas, again resulting from the degradation of silicones. As their combustion forms particles of silicates and microcrystalline quartz, which cause abrasion of combustion engine parts, they pose problems for the use of such gases in combustion engines.

Production
Trimethylsilanol cannot be produced by simple hydrolysis of chlorotrimethylsilane as this reaction leads to the etherification product hexamethyldisiloxane, because of the by-product hydrochloric acid.

Trimethylsilanol is accessible by weakly basic hydrolysis of chlorotrimethylsilane, since the dimerization can thus be avoided. Trimethylsilanol can also be obtained by the basic hydrolysis of hexamethyldisiloxane.

Reactions 
Trimethylsilanol is a weak acid with a pKa value of 11. The acidity is comparable to that of orthosilicic acid, but much higher than the one of alcohols like tert-butanol (pKa 19). Deprotonation with sodium hydroxide gives sodium trimethylsiloxide.

TMS reacts with the silanol groups (R3SiOH) giving silyl ethers.

Structure
In terms of its structure, the molecule is tetrahedral.  The compound forms monoclinic crystals.

Additional properties
The heat of evaporation is 45.64 kJ·mol−1, the evaporation entropy 123 J·K−1·mol−1. The vapor pressure function according to Antoine is obtained as log10(P/1bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766K and C = −44.888K in a temperature range from 291K to 358K. Below the melting point at −4.5 °C, The 1H NMR in CDCl3 shows a singlet at δ=0.14 ppm.

Bioactivity
Like other silanols, trimethylsilanol exhibits antimicrobial properties.

PDMS stamp. PDMS stamps are pieces of polydimethylsiloxane (PDMS), a silicone, that have been patterned usually against a master mold to form a relief pattern used in soft lithography. This PDMS stamp can be used in either its current form as a relief surface for techniques such as microcontact printing or can also be attached to an external source by tubing so that liquid may be passed through channels on its surface. In this second case it will often be laminated to a surface so that chemistry can be performed on that surface producing a pattern of the PDMS stamp on to the surface. Alternatively a PDMS stamp can be laminated to a second piece of PDMS to form a contained device. It is possible to pattern PDMS with nanometre resolution.

PDMS stamps can be procured from some commercial sources such as Research Micro Stamps.

Many techniques have been developed to modify the basic setups to perform a range of tasks such as assays on small volumes. These kinds of devices are often referred to as microfluidic devices.  Because of the small dimensions of these devices flow is laminar, not turbulent, which can lead to many useful properties; however, this reduces the ability of fluid streams to mix.

A new concept of PDMS stamp for multiplexing: the macrostamp
The main drawback of microcontact printing for biomedical application is that it is not possible to print different molecules with one stamp. To print different (bio)molecules in one step, a new concept is proposed : the macrostamp. It is a stamp composed of dots. The space between the dots corresponds to the space between the wells of a microplate. Then, it is possible to ink, dry and print in one step different molecules.

A new PDMS stamp: the Magnetic Stamp
To apply a homogeneous pressure during the printing step, a magnetic force is used. For that, the stamp is sensitive to a magnetic field by injecting iron powder into a second layer of PDMS. This force can be adjusted for nano and micro-patterns. Fully automated micro contact printing equipment was developed. It consists of the steps of the micro contact printing process : loading, inking, drying, printing, alignment, cleaning, unloading. A pipeting module is used to deposit some drop of liquids like ethanol. This equipment is named InnoSTAMP40.

Street Hacker. Street Hacker is a hacking simulator game developed by VirtuWeb Interactive. Unlike other hacking simulation games, the in-game engine is made to appear more like an actual computer system similar to the Linux OS/Shell.

Plot
In Street Hacker, the player assumes the role of a hacker who is approached by a crude executive and entrepreneur, Demetrius Mordecai. He sees you as a person with a strong analytical mind, keen intuition and a desire for power. Having no money at your disposal, he hires you as a hacker to do his dirty work. Vince, his chief of operations, helps you get started and accustomed to the game. Being as successful as he is, Demetrius has made quite a few enemies in the corporate world. This is evident by the first few missions he assigns you to, missions in which you are required to disrupt these corporations by sabotaging their servers. Once these missions are completed, Demetrius decides to "retire" you by calling in an anonymous tip to the FBI about who was behind the attacks. Quickly responding, the FBI surrounds your apartment and finds enough evidence to put you away for 4 years.

Two years later, you are freed from prison to serve your remaining two years on parole. Vince, your mentor from the beginning, helps you get back on your feet by hooking you up with a laptop and some cash. He and many of the others who still work for Demetrius are all hoping that you can find enough dirt on him to put him away for life. Too afraid to directly betray him, they all put their support behind you.

Style
Street Hacker focuses primarily on actual forms of hacking (viruses, worms, etc.). The user is given a program with which to order these different programs so that they can perform the various missions assigned to them. Another feature to the game is the infiltration feature, where the user is required to infiltrate a building in order to hack internet access so they can accomplish the different missions that are assigned to them. Similarly to games such as Uplink, Street Hacker is heavily mission-driven, the entire main storyline being propelled by the different missions assigned. For the most part, the in-game dynamics mimic that of an actual operating system (down to the ability to execute programs and view folders). Hacking takes place in a DOS-style command prompt, using commands familiar to computer aficionado (commands such as WHOIS, CONNECT, etc.). It also allows for downloading files from the respective servers which you must connect to for missions (and in some cases for software downloads).

USS Hydra (AK-82). USS Hydra (AK-82), ex MV Eben H. Linnell, was an  commissioned by the U.S. Navy for cargo service in World War II. Hydra was in naval service from 1 January through 19 November 1943 before she was transferred to the U.S. Army for conversion to the Engineer Port Repair ship Madison Jordan Manchester.

Construction

Constructed as a Maritime Commission N3-M-A1 type, initially under Maritime Commission contract by Penn-Jersey Ship Building Co., Camden, New Jersey as MV Eben H. Linnell, with the contract being transferred to Navy during construction. The ship was acquired by the Navy 1 January 1943 before launch on 23 January 1943.

Naval Service

The ship was converted for naval service at Bethlehem Steel, Key Highway, Baltimore, with completion on 27 May 1943. Hydra commissioned 25 September 1943, and arrived at Norfolk, Virginia, 1 October to prepare for her shakedown. For the next month she engaged in various operations, including speed trials and target runs in the Chesapeake Bay. She was loading cargo in Norfolk, Virginia upon transfer to the Army and departed in early November for Boston Harbor 5 November to begin the transfer process where she was decommissioned 19 November 1943 and transferred to the Army the same day.

Army Service

Hydra was renamed by the Army as the Engineer Port Repair ship Madison Jordan Manchester after an Engineer officer killed in the war. Conversion began in the second week of December 1943 with delays plaguing the program and scheduled completion delayed until 31 March 1944. Crew training further delayed the ship. Sailing for the European Theater was not until 8 November 1944 from New York in Convoy HX 303.

Fate

The ship was returned to the Maritime Commission and arrived in the James River National Defense Reserve Fleet on 20 August 1947. There, the ship was put into use on 15 July 1985 as Fleet Service Craft (SS-27) to support maintenance of the fleet until disposal 24 May 1994. Madison Jordan Manchester was berthed at Fairfield Terminal at Baltimore, Maryland before scrapping there.

New York Restoration Project. New York Restoration Project (NYRP) is a non-profit organization that has planted trees, renovated gardens, restored parks, and transformed open space for communities throughout New York City's five boroughs. It is the only citywide conservancy in New York City that brings private resources to spaces that lack adequate municipal support, with the goal to fortify the city's aging infrastructure and creating a healthier environment for those who live in the most densely populated and least green neighborhoods.

History 
On July 7, 1995, Bette Midler founded the nonprofit New York Restoration Project (NYRP), with the goal of revitalizing neglected neighborhood parks in economically disadvantaged neighborhoods of New York City. These include Sherman Creek Park, Highbridge Park, Fort Washington Park, and Fort Tryon Park in upper Manhattan; and Roberto Clemente State Park and Bridge Park in the Bronx. The New York City Department of Parks and Recreation initiated a partnership with NYRP in 1995 to assist with cleaning and maintaining Fort Tryon Park.

In May 1999, the city planned to auction 114 community gardens for commercial development. Midler and NYRP founding president, Joseph Pupello, led a coalition of greening organizations to save them. NYRP worked closely with the City of New York and took ownership of fifty-two of the most under-resourced gardens in New York City's most economically challenged communities.

In 2007, NYRP became the private partner of Michael Bloomberg's MillionTreesNYC campaign to plant one million new trees in New York City by 2015.

In 2013, Midler won the Jane Jacobs Medal for her work through NYRP. The Rockefeller Foundation Jane Jacobs Medal recognizes New Yorkers who intervene in and use the urban environment to build a more equitable city.  Rockefeller Foundation President, Judith Rodin said: "It is completely appropriate for us to honor Ms. Midler's work in light of her work to bring verdant recreational space to so many New Yorkers in so many different communities."

Media (AK-83). Media (AK-83) was a World War II US navy ship that was never commissioned and thus never bore the USS designation.

Media (AK-83) was contracted to be built as Oliver R. Mumford under Maritime Commission contract 4 September 1941 as a type N3-M-A1 cargo ship. She was acquired by the Navy 1 January 1943 before being laid down by Penn-Jersey Shipbuilding Corp., Camden, New Jersey, 28 January 1943; launched 29 August 1943; sponsored by Mrs. Ernest G. Bornheimer;  completed and delivered to Navy on 17 November 1943.

That same day Media was delivered to the U.S. Army and struck from the Navy list on  24 November 1943. The ship was renamed Glenn Gerald Griswold after an engineering officer killed while fighting a dump fire in Naples, Italy. The Glenn Gerald Griswold was converted into a port repair ship by the Bethlehem Fairfield Shipyard, Baltimore, Maryland, on 5 June 1944 and sailed for Europe by summer's end. After the postwar work the ship was placed in the reserve fleet.
