Vietnam Mechanics Association VAM-1. The Vietnam Mechanics Association VAM-1 (VAM short for Vietnam Association Mechanics) is a Vietnamese ultralight aircraft developed by the Vietnam Mechanics Association in the 2000s. It is based on the Spectrum Beaver RX-550.

Development and design 
On 14 April 2003, Vietnamese Prime Minister Phan Văn Khải signed the 55/TB-VPCP–18/4/2003 official despatch, allowing the Vietnam Mechanics Association () to build a two-seat propeller-driven plane.

In 2003, Phạm Duy Long went to Canada to study piloting and light aircraft technology. With financial support from Overseas Vietnamese investors, construction of the prototype began in April 2003 under the leadership of Vimar Nguyễn and . The VAM-1 was announced in August, the prototype completed in September, and the first flight being scheduled in the later months.

A Spectrum Beaver RX-550, registered as C-IBUN in Canada and owned by Vimar Nguyễn, formed the basis for the VAM-1. The VAM-1 has fixed tricycle landing gear. The flight controls are conventional and manual, and the ailerons are full-span. It has a boom-mounted tail section and sweptback leading edges. The structure is made of aluminium tubes. It is also fabric-covered. The experimented engine was a Rotax engine, which produced about . About 20% of the VAM-1, including the landing gear and controls, are modified to fit the conditions in Vietnam.

However, the aircraft did not receive any licences to fly, and the VAM-1 did not take off for a further two years. Nonetheless, the plane performed its first taxiing runs on 28 March 2004. On 8 December 2005, the VAM-1, with pilot Phạm Duy Long at the controls, took off for its maiden flight, with the aeroplane taking off and landing three times.

In 2006, Nguyễn Văn Đạo died following a traffic accident. Đạo's sudden death led to the project encountering several problems, and the project was eventually abandoned. The VAM project's largest supporter, former Prime Minister Võ Văn Kiệt, also died in 2008.

Cation–cation bond. Cation-cation interactions often occur between molecular cations of transition metals and f-elements (so-called yl cations). They are distinguished as a separate type of intermolecular interactions, since without taking them into account, cations usually repel each other in accordance with Coulomb's law.

Cation-cation interactions in f-elements 
Of particular interest are cation-cation interactions between actinide cations - uranium, in the form of uranyl UO22+, neptunium in the form of neptunoyl NpO22+, plutonium and americium, which are essentially a manifestation of specific complex formation. They are a special case of intermolecular interactions that occur in molecular ions. It was first discovered when studying the behavior of netunium(V) compounds in solutions of uranyl perchlorate. Great impact to crystallochemistry of cation-cation bonds was made by Mikhail Grigoriev. 

The cation-cation interaction [NpO2]+ determines the crystal structure of Np(V) compounds, and the strength of cation-cation bonds between neptunoyl ions in a solid is comparable to the strength of ordinary bonds with acid ligands, although in an aqueous solution, apparently, the role There are somewhat fewer of these connections. In an organic solution, the intensity of C-C interactions can remain high [1]. In the absence of mutual coordination of neptunium ions, Np(V) compounds can exhibit both structural similarity with An(VI) compounds and fundamental differences (showing a tendency to unite Np coordination polyhedra through common equatorial edges. Cation-cation interactions can be detected not only by data from structural studies, but also according to vibrational spectroscopy data. For uranyl, cation-cation interactions are also recorded in the gas phase.

Cation-cation interactions in transition metal ions 
For transition metals, cation-cation interactions appear in nitrene complexes. Nitrenium ligands provide an excellent platform for the simple and efficient synthesis of extremely rare complexes that have positively charged ligands coordinated to positively charged metals to form stable cation-cation and cation-dication coordination bonds.

Funicular curve. In architecture, the funicular curve (also funicular polygon, funicular shape, from the , "of rope") is an approach used to design the compression-only structural forms (like masonry arches) using an equivalence between the rope with hanging weights and standing arch with its load. This duality was noticed by Robert Hooke in 1675 ("as hangs the flexible line, so, but inverted, will stand the rigid arch"). If the hanging rope carries just its own weight (in this case it is usually called a "chain" and is equivalent to a free-standing arch with no external load), the resulting curve is a catenary. 

In graphic statics, a funicular polygon is a graphic method of finding out the line of action for a combination of forces applied to a solid body at different points, a complement to the force polygon used to obtain the value and direction of the resultant force. Both polygons were introduced by Pierre Varignon (Nouvelle Mecanique ou Statique, 1725) and became the basis of the graphic statics in the second half of the 19th century.

Hanging chain model
Multiple ropes with weights can be connected together forming a hanging chain model of a complete structure. The uses of this "outlandish", complicated in comparison with even pre-computer techniques, like graphic statics, method were rare, yet interesting. Usually the technique was used for planar structures as well as the ones with rotational symmetry, like domes. The method can also be applied to arbitrary three-dimensional structures, as first shown by Gaudi while designing the church of Colònia Güell. Gaudi had built a 1:10 scale hanging chain model of the church that did not survive. He also used a smaller copy that was at the time stored in the Sagrada Família basilica. This small model, on exhibit at the museum of the basilica, is often misinterpreted as a model of the basilica itself.

Barbara Bollard. Barbara Anne Bollard also known as Barbara Breen and Bollard-Breen, is a New Zealand academic, and is a professor at University of Wollongong. She was previously a full professor at Auckland University of Technology, specialising in using remote sensing and drones to map and manage conservation areas.

Academic career

Bollard attributes her love of science to her father, New Zealander John Bollard, who was involved in the development of solid fuel propellants for the US space programme, and had been involved in training John Glenn. Bollard completed a PhD titled Integrating social and biophysical data to develop and evaluate marine protected area planning at a local scale: the 1998 Cairns Area Plan of Management as a case study  at James Cook University in 2006. Bollard then joined the faculty of Auckland University of Technology, rising to full professor in 2022. She is now a professor at the University of Wollongong.

Bollard's describes herself as a "techno-nerd". Her research focuses on using geospatial mapping, including remote sensing and drone technology, for the identification and management of protected areas. She has used these techniques to map three areas in Antarctica, as well as deserts in Namibia. She is also exploring how the three-dimensional maps created for conservation planning can also be used in gaming, allowing a virtual experience of remote environments. Bollard's work to create a photo-mosaic of the area around Scott Base was featured in the National Geographic and Antarctica New Zealand-produced programme Continent 7: Dangerous Science. In summer 2023 Bollard worked with researchers from the University of Wollongong and Queensland University of Technology on an Australian Antarctic Division project to map moss beds around Casey Station, to better understand the areas at risk and the effects of climate change.

Howard C. Kauffmann. Howard C. Kauffmann Jr. (February 25, 1923 – May 3, 2016) was an American engineer and oilman. Kauffmann joined the Standard Oil Company of New Jersey (called Exxon after 1972) in 1946 and over the ensuing decades rose through the company's ranks. In 1975 he was appointed president and held the position until his retirement in 1985.

Biography
Kauffmann was born on February 25, 1923, in Tulsa, Oklahoma. In 1943, he graduated from the University of Oklahoma with a bachelor's degree in mechanical engineering. After serving as an engineering officer in the U.S. Navy during World War II, Kauffmann commenced his nearly 40-year career in the petroleum industry.

In 1946, Kauffmann joined the Carter Oil Company, an affiliate of Standard Oil Company of New Jersey. Over the next three decades at Exxon, he progressed through roles spanning engineering, oil field supervisory positions, and assignments overseas. His key positions included Producing Coordinator at International Petroleum Company Limited and executive roles at Exxon's South American and European affiliates.

In 1974, Kauffmann was elected to Exxon's board of directors and named a Senior Vice President. The following year, he was appointed President of Exxon, succeeding Howard Page. He took office during a period of significant industry changes and public animosity towards major oil companies in the wake of the 1973 oil crisis. Kauffmann sought to diversify Exxon's business interests into new areas like nuclear power, solar energy and batteries. However, these initiatives failed to offset declining production prospects in oil and proved to be unsuccessful. By the mid-1980s Exxon had largely divested them to refocus efforts on petroleum.

Kauffmann retired from Exxon in 1985 after ten years as President. His tenure was characterized as competent stewardship during a difficult transitional period for the oil industry.

After retiring from Exxon, Kauffmann served on the Boards of Directors for several major corporations like Chase Manhattan Bank, United Technologies and Pfizer. He also held leadership roles in industry organizations and non-profits. Additionally, he co-ran a custom cabinetry business for several years.

Kauffmann died on May 3, 2016, at his home in Atlanta, Georgia at the age of 93. He was survived by his wife, four children, seven grandchildren, and one great grandchild.<ref name="dignitymemorial"

Karabo (software). Karabo is an open source SCADA (supervisory control and data acquisition) framework developed at the European X-ray Free Electron Laser facility since 2010. The framework can be used to build a distributed control system, in which concrete functionality such as hardware control, or a command sequence, is implemented in form of so-called devices. Devices may be implemented in Python or C++.

Similar to systems like EPICS and TANGO, Karabo is developed chiefly with control of large scientific infrastructure and experiments in mind. The system emphasises fully asynchronous, and event driven distributed messaging via a central message broker (AMQP/RabbitMQ). Developers can additionally leverage tightly integrated peer-to-peer (P2P) TCP channels to transfer large data volumes at rates of multiple gigabytes per second. A standalone graphical user interface (GUI) client application, which can be used to design and view synaptic views of the distributed system, is provided alongside the framework.

At the European XFEL, Karabo is used to operate the photon systems and experiment end stations (instruments) of the facility. In 2023, the EuXFEL control system integrated 3.5 million control parameters distributed over 25,000 devices on ca. 100 physical servers. Additionally, the facility's scientific data acquisition system, and online detector calibration pipelines are implemented in Karabo, and process data rates of approximately 20Gbyte/s.

Karabo is free and open source software under the MPL2 (framework) and GPL3 (GUI application) licenses.
