David Boger. David Vernon Boger  (born 13 November 1939) is an Australian chemical engineer.

In 2017, Boger was elected a member of the National Academy of Engineering for discoveries and fundamental research on elastic and particulate fluids and their application to waste minimization in the minerals industry.

Life
He graduated from Bucknell University with a B.S. where he studied with Robert Slonaker, and from University of Illinois with an M.S. and Ph.D.

He teaches at Monash University, the University of Melbourne, and the University of Florida. He is one of three inaugural Laureate Professors at the University of Melbourne.

Work 
Boger is known for his studies of non-Newtonian fluids (which behave both as liquids and solids) which have improved the understanding of how this group of fluids flow and led to major financial and environmental benefits. Boger discovered 'perfect' non-Newtonian fluids, which are elastic and have constant viscosity and are now known as Boger fluids, which enabled him to explain how non-Newtonian fluids behave. He was able to apply his ideas to improve the disposal of "red mud", a toxic waste produced during the manufacture of aluminium from bauxite and a major environmental problem. His findings have also led to improved inks for industrial inkjet printers, insecticide chemicals that spread evenly on leaves and reduced drag in oil pipelines.

He was elected to the Fellowship of the Australian Academy of Science in 1993 and served on the Council of the Australian Academy of Science from 1999 to 2002. He was awarded the Matthew Flinders Medal and Lecture in 2000. In 2007 he was elected Fellow of the Royal Society and of the Royal Society of Victoria.

John Jeppson. John Jeppson (1844–1920) was an American  industrialist. Jeppson  was a founder  and Chief Engineer  of the   Norton Emery Wheel Company (now Norton Abrasives) of Worcester, Massachusetts.

Life
Jeppson was born on July 1, 1844, in Höganäs, Sweden. Jeppson’s father was a carpenter and several of his ancestors were mechanics. Jeppson went to school in his birthplace, but at the age of 12 went to work in a pottery and brick factory. At the age of 16 Jeppson learned how to manufacture architectural ornaments. He worked in the pottery and brick factory until the age of 24.

In 1868, around the age of 25, he decided to try his luck to America. When he arrived in America he gained employment with Norton in Worcester, MA, which at this time only produced pottery. Jeppson became very skilled at his profession and earned the highest salaries. In 1873 Jeppson managed to produce an artificial emery grinding stone. He continued his experiments and in 1885 the Norton Emery Wheel Company was created with Jeppson as one of the founders. Jeppson became the company’s first plant manager. Jeppson then went on to become the Chief Engineer of the Norton Emery Wheel Company. He maintained this position until his death.

At the time of Jeppson’s death in 1920, Norton Company had twelve employees and two ovens.  After subsequent expansion, the company operated multiple ovens and a complex consisting of some 50 buildings in Worcester. The company also opened up factories in Canada, France and Germany. In 1990 Norton Abrasives was purchased by Compagnie de Saint-Gobain, a French -based multinational corporation.

Personal life
In 1916, Jeppson became a Knight First Class of the Royal Order of Vasa as appointed by the King of Sweden.
John Jeppson died during  1920 and was buried in the Old Swedish Cemetery at Worcester, Massachusetts.

John Jeppson married  Thilda  Ahlstrom (1847-1925). 
Their son George Nathaniel Jeppson (1873–1962) and grandson John Jeppson II (1916-2013) would continue the family legacy at Norton, both serving as president and CEO.

John Jeppson Award
The John Jeppson Award which originated in 1958 is one of the most prestigious awards given by the American Ceramic Society. The award recognizes distinguished scientific, technical, or engineering achievements in ceramics.

Network diagram software. A number of tools exist to generate computer network diagrams. Broadly, there are four types of tools that help create network maps and diagrams:

 Hybrid tools
 Network Mapping tools
 Network Monitoring tools
 Drawing tools

Network mapping and drawing software support IT systems managers to understand the hardware and software services on a network and how they are interconnected. Network maps and diagrams are a component of network documentation. They are required artifacts to better manage IT systems' uptime, performance, security risks, plan network changes and upgrades.

Hybrid tools 
These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams. Typical capabilities include but not limited to:
 Displaying port / interface information on connections between devices on the maps
 Visualizing VLANs / subnets
 Visualizing virtual servers and storage
 Visualizing flow of network traffic across devices and networks
 Displaying WAN and LAN maps by location
 Importing network configuration files to generate topologies automatically

Network mapping tools 
These tools are specifically designed to generate automated network topology maps. These visual maps are automatically generated by  scanning the network using network discovery protocols. Some of these tools integrate into documentation and monitoring tools. Typical capabilities include but not limited to:
 Automatically scanning the network using SNMP, SSH, WMI, etc.
 Scanning Windows and Unix servers
 Scanning virtual hosts
 Scanning routing protocols
 Performing scheduled scans
 Tracking changes to the network
 Notifying users of changes to the network

Network monitoring tools 
Some network monitoring tools generate visual maps by automatically scanning the network using network discovery protocols. The maps are ideally suited for viewing network monitoring status and issues visually. Typical capabilities include but not limited to:
 Automatically scanning the network using SNMP, WMI, etc.
 Scanning Windows and Unix servers
 Scanning virtual hosts
 Scanning routing protocols
 Scanning connection speeds
 Performing scheduled scans
 Tracking changes to the network

Drawing tools 
These tools help users to create network topology diagrams by adding icons to a canvas and using lines and connectors to draw linkages between nodes. This category of tools is similar to general drawing and paint tools. Typical capabilities include but not limited to:
 Libraries of icons for devices 
 Ability to add shapes and annotations to maps
 Ability to create free-form diagrams

IJsseloog. The IJsseloog (, "IJssel eye") is an artificial island in the Ketelmeer (province of Flevoland, the Netherlands) used as a depository to store polluted silt. Most of the polluted silt was deposited in the Ketelmeer by the IJssel river between 1950 and 1990. Removal of silt soil from the Ketelmeer lake also aims to deepen the channel leading to the mouth of the IJssel to at least a depth of , thus aiming to improve access to the river for navigation.

Construction of IJsseloog started in 1996 and was completed in 1999. During construction of the IJsseloog, a major concern was to preserve the water table and the environment of Ketelmeer. The polluted silt is to be stored permanently and without any risk of leakage. To avoid nuisance to agriculture, to local residents, and to prevent groundwater contamination, the silt depository was built in the centre of the lake and not on the coast. IJsseloog is also a target for recreational and ecological development. Two other artificial islands were created: Hanzeplaat and Schokkerbank.

The dredgings are being stored in a man-made island depot in the middle of the Ketelmeer. One kilometer across and fifty meters deep, the depot is designed to hold 23 million cubic meters of sludge, of which 15 million cubic metres from the Ketelmeer, and the rest from elsewhere. To prevent leakage, the floor of the depot is sealed with clay and the dike is lined with foil. The water level is held below that of the lake, to prevent pollution runoff.

A port was built on the outer edge of the IJsseloog for delivery of silt. Once the depot is full, remediation will be done by decantation. Clean silt will be used to construct a new ecological zone, the IJsselmonding. The clean sludge that is released will be used for the construction of a natural IJssel estuary.

A treatment plant began operating in 2000. Its processing station separates sand and peat from contaminants. Purified sand will be used for construction, and the remaining sludge is pumped to storage. When storage is full, the layers of clay and sand will be sealed, and the island itself will be used for recreational purposes.
After that process, nature will take over in the IJsseloog.

Tetraethylene glycol dimethyl ether. Tetraethylene glycol dimethyl ether (TEGDME or tetraglyme) is a polar aprotic solvent with excellent chemical and thermal stability. Its high boiling point and stability makes it an ideal candidate for separation processes and high temperature reactions. TEGDME is also used in lithium-ion battery technology and combined with trifluoroethanol as a working pair for organic absorption heat pumps.

TEGDME is listed as a Substance of Very High Concern under REACH regulations.

Kinematic wave. In gravity and pressure driven fluid dynamical and geophysical mass flows such as ocean waves, avalanches, debris flows, mud flows, flash floods, etc., kinematic waves are important mathematical tools to understand the basic features of the associated wave phenomena. 
These waves are also applied to model the motion of highway traffic flows.

In these flows, mass and momentum equations can be combined to yield a kinematic wave equation. Depending on the flow configurations, the kinematic wave can be linear or non-linear, which depends on whether the wave phase speed is a constant or a variable. Kinematic wave can be described by a simple partial differential equation with a single unknown field variable (e.g., the flow or wave height, ) in terms of the two independent variables, namely the time () and the space () with some parameters (coefficients) containing information about the physics and geometry of the flow. In general, the wave can be advecting and diffusing. However, in simple situations, the kinematic wave is mainly advecting.

Kinematic wave for debris flow 

Non-linear kinematic wave for debris flow can be written as follows with complex non-linear coefficients:

where  is the debris flow height,  is the time,  is the downstream channel position,  is the pressure gradient and the depth dependent nonlinear variable wave speed, and  is a flow height and pressure gradient dependent variable diffusion term.
This equation can also be written in the conservative form:

where  is the generalized flux that depends on several physical and geometrical parameters of the flow, flow height and the hydraulic pressure gradient. For  this equation reduces to the Burgers' equation.

GNR Class O1. The Great Northern Railway (GNR) Class O1 was a class of two-cylinder 2-8-0 steam locomotive designed by Nigel Gresley for heavy freight work and built by the GNR between 1913 and 1919.

History
Gresley designed the O1 2-8-0 for the heavy coal trains on the mainline from Grantham to London, ordering five examples 1913, which were completed at Doncaster in 1914. A further fifteen were ordered in January 1916, but due to the First World War delays were incurred and construction was transferred to the North British Locomotive Company, who delivered the first ten in April 1918, followed by a further five in October and November 1919.

The class was re-designated O3 by the London and North Eastern Railway in 1944 to release the O1 classification for use with the LNER Thompson Class O1 introduced during the Second World War.

British Railways
Seventeen examples survived into British Railways ownership in 1948, but all had been withdrawn by 1952 and scrapped after World War 2 .

Energy in Luxembourg. Energy in Luxembourg describes energy and electricity production, consumption and import in Luxembourg. Electricity sector in Luxembourg is the main article of electricity in Luxembourg.

Primary energy use in Luxembourg was 48 TWh in 2009, or 98 TWh per million inhabitants.

Luxembourg is a net energy importer; 81.5% of the electricity consumed in the country, for example, was imported from neighboring European countries in 2021.

Overview 

There was no decline in the climate change gas emissions () from year 2008 to 2012 in Luxembourg. There was no better efficiency in the use of electricity from 2008 to 2012.

Electricity 

In 2008, electricity use per person in Luxembourg was 2.6 times greater than in the United Kingdom.

The 1970s energy crisis led Luxembourg to briefly consider constructing a nuclear power plant. In 1972 RWE and the government negotiated a project to build a 1,200 MW nuclear reactor along the Moselle river near Remerschen. In 1974 there were already signs that there was little support for the project among public opinion. The opposition to the project grew, and became more organized, ultimately forcing the government to cancel the project at the end of 1977.

Subsequently, the construction of the large French Cattenom Nuclear Power Plant in 1979 close to the Luxembourg border caused tensions between the two countries.

Renewable energy 

By 2021, renewable energy produced 80% of electricity generated in Luxembourg, comprising wind power at 26%, solar power at 17%, hydro power at 8%, and other renewables (bioenergy, etc) at 29%.

Luxembourg firms are less likely than those throughout the EU to invest in onsite/offsite renewable energy generation (26% versus 41%) and energy efficiency (43% against 59%). Energy prices are also cited by Luxembourgish businesses (84%) as uncertainty about the future as their top long-term investment obstacles.

Climate change

Emissions of carbon dioxide in total, per capita in 2007 were 22.4 tons CO2 compared to EU 27 average 7.9 tons .

1990 emissions were 13 Mt eqKyoto protocol target is reduction of 4 Mt (28%).

In Luxembourg, 54% of enterprises have invested in mitigating weather-related consequences and lowering carbon emissions. This is close to the current [when?] EU average of 56%.
