Ikha Pokhari. Ikha Pokhari (Nepali:इखा पोखरी) or Ekha Pukhu is a historic pond in Chhetrapati, Kathmandu. The surface area of the pond is about seven ropanis. The pond has dried up due to siltation and over extraction of water. Land encroachment has been taking place around the pond. A public school, Kanya Mandir school lies just next to the pond. Legally, the pond is registered to the school.
 
Before it dried up, the pond was used for various rituals by locals, mainly Newar people. Locals are planning to revive the pond.

There were two additional ponds nearby Ikha pokhari, however due to land encroachment, these ponds have disappeared.

Decauville railway of La Guerche-sur-l'Aubois. The Decauville railway of La Guerche-sur-l'Aubois was a horse-drawn narrow-gauge railway, which operated around 1910 at the Daumy, Boucheron & Cie lime and cement factory in La Guerche-sur-l'Aubois.

History 
One of the founders of the company has originally been producing hydraulic lime, a building material that hardens both in the air and under water. His factory, Daumy Ainé et Cie, was initially, around 1869, located in Beffes near Jouet,  to the north.

Route 
Old postcards and the stationery used by Daumy, Boucheron & Cie around 1910 show all the means of transport they used. The lime was taken by the  gauage Decauville railway from the quarries below the church, to the limekilns, slaking ponds and grinding mills, and finally to the shipping points for the finished products on the railway and the Berry Canal. However, contrary to what is shown in the artistic impression, the factory was located about  away from the Berry Canal on the other side of the town centre of La Guerche.

Edmond–Ogston model. The Edmond–Ogston model is a thermodynamic model proposed by Elizabeth Edmond and Alexander George Ogston in 1968 to describe phase separation of two-component polymer mixtures in a common solvent. At the core of the model is an expression for the Helmholtz free energy 

 

that takes into account terms in the concentration of the polymers up to second order, and needs three Virial coefficients  and  as input. Here  is the molar concentration of polymer ,  is the universal gas constant,  is the absolute temperature,  is the system volume. It is possible to obtain explicit solutions for the coordinates of the critical point 

 ,

where  represents the slope of the binodal and spinodal in the critical point. Its value can be obtained by solving a third order polynomial in ,

 ,

which can be done analytically using Cardano's method and choosing the solution for which both  and  are positive. 

The spinodal can be expressed analytically too, and the Lambert W function has a central role to express the coordinates of binodal and tie-lines.

The model is closely related to the Flory–Huggins model.

The model and its solutions have been generalized to mixtures with an arbitrary number of components , with  greater or equal than 2.

Greta Woxén. Greta Anna Maria Woxén was Sweden's first female civil engineer graduating from the Kungliga Tekniska högskolan (KTH) (the Royal Institute of Technology) in 1928.

Early life 
Greta Anna Maria Westberg was born on 12 July 1902 in Denmark. Her father Nils Westberg was an engineer and a collaborator of Swedish industrialist Gustaf Dalén.

Education 
Greta Westberg completed her secondary school education in 1920 and passed the Studentexamen, the school-leavers' university entrance examination in Sweden.

She then began working at the Vattenfallsstyrelsen, a Swedish multinational power company owned by the Government of Sweden. After taking a short basic course in electrical engineering at work, she became interested in studying engineering. Her three brothers had studied at Kungliga Tekniska högskolan.

Kungliga Tekniska högskolan (Royal Institute of Technology) had opened its doors to women students in 1921, and Brita Snellman was the first woman to take advantage of this opportunity in the same year, studying architecture. Greta Westberg was the first woman in Sweden to begin a master's degree in engineering when she entered KTH's department of electrical engineering in 1924. She was nicknamed "Electric Girl". (Vera Sandberg), who graduated from Chalmers University of Technology in 1917 with a bachelor's degree, is considered Sweden's first female engineer. Chalmers' courses at the time were shorter than that at KTH, and it took until 1937 before Chalmers became a technical college and was allowed to issue master's degrees). Brita Snellman graduated in 1924, the same year that Westberg began her studies, which meant Westberg was the only female technologist at the entire KTH for part of her time there. During her degree, she formed the Kvinnliga Teknologföreningen, the Women Technologists' Association, with two other women technologists, who started their courses later, one studying Architecture and the other Chemistry. She graduated from the Kungliga Tekniska högskolan (KTH) the Royal Institute of Technology in 1928.

Career 
After graduating, Greta Woxén quickly got a job at Elektricitetverksföreningen, the Swedish energy company, where she worked with operating statistics for just over a year. She married in 1929 and had to resign to raise her children. Once her children were grown, she returned to work in 1954 as a teacher of mathematics, physics and chemistry.

Personal life 
Greta Westberg married mechanical engineer Ragnar Woxén in 1929. He had also graduated in engineering in 1928, and later (1943–1964) became KTH's Rector. As early as 1927, the couple had edited and published Föreläsningar i läran om hiss- och transportanordningar, a collection of Lectures in the Doctrine of Elevators and Transport Devices. They had five children, Iva, Harald, Anna, Gerda and Gustav.

Greta Woxén died 9 May 1993 in Lidingö.

Commemoration 
A room is named after Greta Woxén at Kungliga Tekniska högskolan.

ETAP 23iL. The ETAP 23iL is a Belgian trailerable sailboat that was designed by Jacques de Ridder as a cruiser and first built in 1994.

Production
The design was built by ETAP Yachting in Belgium between 1994 and 1999, with 100 boats completed, but it is now out of production.

Design
The ETAP 23iL is a recreational keelboat, built predominantly of polyester glassfibre-foam sandwich construction, with wood trim. The use of foam sandwich construction makes the boat unsinkable. It has a 7/8 fractional sloop masthead sloop rig with aluminum spars, a deck-stepped mast, wire standing rigging and a single set of swept spreaders. The hull has a slightly raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a lifting keel with a weighted bulb. It displaces  and carries  of cast iron ballast.

The boat has a draft of  with the lifting extended and  with it retracted, allowing beaching or ground transportation on a trailer.

The boat is normally fitted with a small  outboard motor for docking and manoeuvring.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settees in the main cabin. The galley is located on the port side just aft of the bow cabin. The galley is equipped with a two-burner stove, an icebox and a sink. The head is located in the bow cabin on the port side, under the "V"-berth. The fresh water tank has a capacity of 

For sailing downwind the design may be equipped with an asymmetrical spinnaker of . It has a hull speed of .

Operational history
The boat was at one time supported by a class club, the ETAP Owners Association.

A review in Boat Specs, notes "the Lifting keel version features an appendage configuration without compromise between draft and performance. Only drawback: some space is taken inside by the keel."

A review in the Yacht Charter Guide described the design, "the ETAP 23iL is a very safe, fast seagoing yacht with a long waterline. It can sail superbly close to the wind and, in the hands of an experienced crew, it handles easily even in the roughest conditions. This yacht features a regatta deck which allows every manoeuvre - even reefing - to be carried out from the cockpit. Below deck there's a comfortable, luxuriously finished and almost condensation-free cabin with ample stowage space and a very convenient navigation area with a chart table and instruments' panel. The lifting keel allows the ETAP 23iL to be trailered easily..."

Karl Norum. Karl Martin Norum (1852—1911) was a Norwegian architect, best known for his many church buildings, as well as contributions to the reconstruction after the fire in the city of Ålesund in 1904. Norum is well known for his Art Nouveau and Dragestil designs.

Norum was born in 1852 in Levanger, Norway. He was educated at the Trondheim Technical College from 1872 to 1875. From 1875 to 1880, he worked for the Rørosbanen railway line as a surveyor during the construction of the railway line. In 1880, he was hired as a draftsman for the architectural firm of Jakob Digre in Trondheim. In 1884, he was hired as an assistant in the engineering office for the city of Trondheim.

In 1886, he was hired as the chief architect and designer for the architectural firm of Jakob Digre, where he worked earlier in his career. The firm had several architects and Norum worked here for 25 years. During this time, Norum was known for the dragestil style of many of the church buildings he designed such as Stangvik Church (1896), Frei Church (1897), Sortland Church (1901), Steinkjer Church (1902), Neiden Church (1902), Levanger Church (1902), Namsos Church (1903), Buksnes Church (1905), Veøy Church (1907), Holm Church (1907). He was also involved in the renovation of the Hammerfest Church in 1892.

In Trondheim, Norum was also the designer of a number of public and industrial buildings such as the Britannia Hotel (1895), Mathesongården (1898), Hjorten Revue and Variety Theater restaurant (1899), the Bødtker family's villa Kvernbekken (1902), the local Masonic Lodge, Trondheim hospital on Øya (1902),  the main post office (1911), and Tollboden (1911). Most were in designed in an Art Nouveau and built out of stone.

While working in Ålesund (1904–1907) to rebuild after a city-wide fire, he was the architect of almost ten buildings, perhaps the most famous being the  wide apartment building (located at Kongens gt. 10B) which is the country's narrowest apartment building. He also designed the commercial building "Carl E. Rønneberg & Sønner" on Noteneset.

ETAP 28i. The ETAP 28i is a Belgian sailboat that was designed by French designers Philippe Harlé and Alain Mortain (Harlé-Mortain), as a cruiser and first built in 1988.

Production
The design was built by ETAP Yachting in Belgium from 1988 to 1997 with about 450 boats completed, but it is now out of production.

Design
The ETAP 28i is a recreational keelboat, built predominantly of polyester glassfibre-foam cored sandwich, with wood trim. It has a 7/8 fractional sloop rig with aluminum spars, a deck-stepped mast, wire standing rigging and a single set of swept spreaders. The hull has a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel, with a lifting keel optional. It displaces  and carries  of cast iron ballast.

The foam-cored construction renders the boat unsinkable.

The boat has a draft of  with the standard keel.

The boat is fitted with a Swedish Volvo 2002 diesel engine of  for docking and manoeuvring. The fuel tank holds  and the fresh water tank has a capacity of .

The design has sleeping accommodation for six people, with a double "V"-berth in the bow cabin, two straight settee quarter berths in the main cabin and an aft cabin with a double berth on the port side. The galley is located on the port side just forward of the companionway ladder. The galley is L-shaped and is equipped with a two-burner stove, an ice box and a sink. The head is located just forward of the aft cabin on the starboard side and includes a hanging locker.

For sailing downwind the design may be equipped with a symmetrical spinnaker of . It has a hull speed of .

Operational history
The boat was at one time supported by a class club, the ETAP Owners Association.

In a 2009 Yachting Monthly review stated, "with a generously roached, fully-battened mainsail and working jib set on a sporty, 7/8 fractional rig and a fixed, deep-fin keel, she is a sharp performer, enjoyable to sail, good for short-handed cruising and ideal for a couple with two children. Some buyers
opted for a lifting keel, which slightly blunts her performance but she still sails well. The main cabin and forepeak are open-plan, under a semi-flush deck, with good headroom up to the forecabin, which is curtained off from the saloon. There is a large aft cabin, a good galley, a spacious heads abaft the companionway and a reasonable chart table."
