Rosemin Manji: Approached by Tom Ford himself, Rosemin Manji learned from the best from the very beginning: “I learned more with Tom Ford than I did in university: managing people, the design process, brand management, and business.  The people I worked with went on to become some of the best designers in the world: Clare Waight Keller, Stefano Pilati, Frida Giannini, Alessandra Facchinietti, Christpher Bailey”, claims Manji.  She then was appointed as the European PR Director at Juicy Couture, setting up the first office and showroom outside America, and responsible for remaking the image of the brand beyond tracksuits, she worked closely with high-end magazines and dressed well known personalities including Gwyneth Paltrow, Kate Moss, Madonna, Kate Winslet, Queen Rania of Jordan and Sienna Miller.  Manji moved to Dubai in 2007, where she started her own multi-brand showroom representing Givenchy, Tom Ford and Christian Louboutin, offering a plethora of services including styling, brand advisory and niche events.  She also worked directly with Hermes, Prada, Chanel and Roger Vivier on special projects.

Icefall: Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows.  Most glacier ice flows at speeds of a few hundred metres per year or less.  However, the flow of ice in an icefall may be measured in kilometres per year.  Such rapid flow cannot be accommodated by plastic deformation of the ice.  Instead, the ice fractures forming crevasses. Intersecting fractures form ice columns or seracs.  These processes are imperceptible for the most part; however, a serac may collapse or topple abruptly and without warning.  This behavior often poses the biggest risk to mountaineers climbing in an icefall.

Global hectare: The global hectare (gha) is a measurement unit for quantifying both the ecological footprint of people or activities as well as the biocapacity of the earth or its regions.  One global hectare represents the average productivity of all biologically productive areas (measured in hectares) on earth in a given year.  Examples of biologically productive areas include cropland, forests, and fishing grounds; they do not include deserts, glaciers, and the open ocean.  "Global hectare per person" refers to the amount of biologically productive land and water available per person on the planet.  The total number of global hectares is approximately 11.3 billion, averaging about 1.8 global hectares per person (2004).  A total of 13.4 billion hectares were used, or 2.2 global hectares per person, meaning about 20% more was consumed than produced.  This is possible because there are natural reserves all around the globe that function as backup food, material and energy supplies, although only for a relatively short period of time.  Due to rapid population growth, these reserves are being depleted at an ever increasing tempo.  See Earth Overshoot Day.

Greater Winnipeg Water District aqueduct: The Greater Winnipeg Water District aqueduct supplies the city of Winnipeg, Manitoba with water from Shoal Lake, Ontario.  It was put in service in 1919 and cost nearly CDN $16 million.  It has a capacity of 85 million Imperial gallons per day (4.4 cubic metres per second) and extends approximately 96 miles (153 km) from an intake structures on Shoal Lake to the Deacon reservoir on the east side of the city.  Water flows by gravity from the lake, since the aqueduct drops about 300 feet (90 metres) over its length.  The Greater Winnipeg Water District Railway was built for construction and maintenance of the aqueduct.  The capacity was planned for a city of one million inhabitants; peak water usage by the city was in 1988 and the capacity of the aqueduct has never been entirely used.  An additional 12-mile (19 km) branch was completed in 1960.

Ermenegildo Zegna: Ermenegildo Zegna (] ) (often abbreviated and known simply as Zegna) is an Italian luxury fashion house that makes men's clothing and accessories.

Nili Patera dune field: Nili Patera is a dune field on Mars.  It is located on top of a lava bed, at the site of an ancient volcano, the Nili Patera caldera of Syrtis Major, near the Martian equator, and it is one of the most active dune fields of Mars.  Its location coordinates on Mars are 8.7° N latitude, 67.3° E longitude.  It is being actively studied by the HiRISE camera, onboard the Mars Reconnaissance Orbiter, at the rate of one image every six weeks.  The study of the movement of the dunes provides information regarding wind variation as a function of time and furthers the study of surface erosion characteristics of the Martian landscape.  This information can then be used for the development and design of future Mars expeditions.  The dunes of the Patera field are of the barchan type and their study by HiRISE was the first one to establish dune and ripple movement of a minimum of 1 m on Mars.  The Patera dune field, was also the first to be investigated using the COSI-Corr software, which was originally developed to analyse the movement of earthbound dunes.  The research results from the evidence provided by the monitoring of the Nili Patera field, indicate sand fluxes of the order of several cubic metres per metre per year, similar to the flux observed at the sand dunes of Victoria Valley in Antarctica.

Ibrahimiya Canal: The Ibrahimiyah Canal is an irrigation canal in Egypt built in 1873.  It was the most important public work executed under the then newly established Ministry of Public Works.  It was built during the reign of Ismail Pasha when he was Khedive of Egypt.  It was commissioned by Bahgat Pasha, minister of public works, who designed it primarily to provide perennial irrigation to the Khedivial sugar estates in Middle Egypt.  It supplied perennial irrigation to 580000 acre and flood irrigation to another 420000 acre .  The discharge of the canal varied between 30 and 80 cubic metres per second in summer and between 500 and 900 cubic metres per second in flood.  Having its head on the left bank of the Nile, in Assiut, it runs northwards for 60 kilometres and then divides in Dairut into two main branches; one branch is the Bahr Yussef Canal, while the other is the Ibrahimiyah Canal proper.
