Renfe Class 309. The Renfe Class 309 is a class of 20 three axle diesel-hydraulic locomotives shunters built by M.T.M. for Renfe, and introduced between 1986-7.

History and design

In the late 1970s Renfe began planning to modernise its shunting locomotives; initially modernisation of the Class 303 with new engines was considered and one locomotive converted, but the experiment was not carried forward. In 1982 Renfe opened bidding for a contract for 50 locomotives of up to . M.T.M. (Maquinista Terrestre y Marítima) offered its own development, and was successful: in July 1983 Renfe placed an order for 20 units.

The first units were delivered in the red-brown/yellow/white estrella livery in 1985 and were accepted into service in 1986 after correction of technical problems.

Initially the property of Renfe, after the creation of Adif the locomotives were divided between Mercancías (formerly Cargas freight) and Adif (infrastructure services). As of 2010 about half have been painted in a red and grey livery.

Paping. Paping (pronounced pah ping) is a computer network administration utility used to test the reachability of a host on an Internet Protocol (TCP/IP) network and to measure the time it takes to connect to a specified port.  The name is a play on the word ping, another computer network administration utility.

Because ICMP can be used to identify the operating system of a remote machine, it is sometimes blocked.  If ICMP is blocked, ping cannot be used to identify if the service is responding.  Publicly available services must keep their relevant TCP or UDP ports open, paping can attempt to make connections to these ports to determine if a service is responding.  Similar utilities such as nmap allow a range of ports to be scanned, however they do not allow you to repetitively scan the same ports.

Paping operates by attempting to connect to an Internet Protocol TCP/IP port on the target.  In the process it measures the time taken for a connection to be established and records any connection failures.  The results of the test are printed in form of a statistical summary of the connections made including the minimum, maximum, and the mean connection times.

Paping is cross-platform software, currently supporting Windows and Linux.

As of April 2013, the project appears to be abandoned with no new fixes or versions being produced.

Proxorphan. Proxorphan (INN), also known as proxorphan tartate (USAN) (developmental code name BL-5572M), is an opioid analgesic and antitussive drug of the morphinan family that was never marketed. It acts preferentially as a κ-opioid receptor partial agonist and to a lesser extent as a μ-opioid receptor partial agonist.

Synthesis

Starting material for this preparation is ketoester 1, available by one of the classical benzomorphan syntheses. Condensation with the ylide from Triethyl phosphonoacetate (HWE reaction) affords diester 2. Catalytic hydrogenation proceeds from the less hindered face to afford the corresponding saturated diester (3). The esters are then reduced by means of LiAlH4 to give the glycol (4); this undergoes internal ether formation on treatment with acid to form the pyran ring of 5. Von Braun reaction with BrCN (or ethyl chloroformate) followed by saponification of the intermediate leads to the 2° amine (6). This is converted to the cyclopropylmethyl derivative 8 by acylation with cyclopropylcarbonyl chloride followed by reduction of the thus formed amide (7) with LiAlH4. Cleaving off the O-methyl ether with sodium ethanethiol affords proxorphan (9).

Hygroelectricity. Hygroelectricity is a type of static electricity that forms on water droplets and can be transferred from droplets to small dust particles.  The phenomenon is common in the Earth's atmosphere but has also been observed in the steam escaping from boilers (see Armstrong effect).  It was the basis for a proposal by Nikola Tesla to tap electricity from the air, an idea which has been recently revived. Hygroelectric charge is the likely source of the electric charge which, under certain conditions such as exist in thunderstorms, volcanic eruptions and some dust storms, gives rise to lightning.

As of 2023, a team at the Lisbon-based Catcher Project have generated a 1.5 V 10 mA current using a 4 cm-diameter device.

Fay automatic lathe. The Fay automatic lathe was an automatic lathe tailored to cutting workpieces that were mounted on centers (tools with pointed ends to accurately position a center-drilled workpiece about an axis, either directly or by using a mandrel). It could also do chucking work (feeding of unformed blanks or pieces of stock from a magazine to be automatically gripped by the machine for turning). Examples of workpieces included automotive steering knuckles and transmission gears, and such work done on mandrels as flanges, disks, and hubs. The machine tool was developed by F.C. Fay of Philadelphia and improved by Otto A. Schaum. It was originally manufactured by the Fay & Scott Machine Shop. James Hartness acquired manufacturing rights on behalf of  the Jones & Lamson Machine Company and manufactured an improved version, developed under the management of Ralph Flanders.

In 1937 Roe, writing for the American Society of Mechanical Engineers, framed the importance of the Fay automatic lathe to the capabilities of machine tools by saying that, "This machine does for the engine lathe what Spencer did for the old hand-operated turret lathe." These machines took an entire class of turned work formerly requiring an operator to execute the series of movements necessary to shape a piece of metal (manual control) and allowed the same work to be done automatically. This step forward in automation lowered a manufacturer's unit expense per part by reducing labor costs. Numerically controlled (CNC) machine tools such as turning centers, turn-mills, and rotary transfer machines have largely supplanted cam-operated automatics.

Dry water. Dry water or empty water, a form of "powdered liquid", is an air–water emulsion in which water droplets are surrounded by a silica coating. Dry water consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid. The result is a white powder.

Discovery and preparation 
Dry water was first patented in 1968 and quickly found use in the cosmetic industry. In 2006, new work with dry water from the University of Hull increased interest in its potential use in other fields. 

Dry water can be made by blending a mixture of silicon dioxide dust with water.

Applications 
Certain gases, when mixed with dry water, combine with the water, which then traps them in a solid clathrate hydrate cage. This presents the possibility that explosive gases could be transported in dry water with a reduced risk of detonation. Dry water was considered for use as a carbon sequestration agent to capture and seal away greenhouse gases from the atmosphere. It can trap four times more carbon dioxide than ordinary water over a similar length of time. Dry water also has applications for the transportation and storage of many dangerous materials. It can be used as a medium for volatile compounds, as materials stored within the dry water can be reduced to powder and stabilized – reducing not only the volatility of the substance, but also its weight for transport. It has also been theorized that dry water could have potential uses in the construction of fuel cells for automobiles due to its ability to store and stabilize very large amounts of volatile gases and materials without permanently binding them. Due to its nature, dry water is classified as an adsorbent material. It has many potential uses in fields where emulsions are used. Recent studies have also found dry water can act as a catalyst.
