North Star 38. The North Star 38 is a Canadian sailboat that was designed by Sparkman & Stephens as a cruiser-racer and first built in 1971.

The North Star 38 is a development of the Hughes 38-2 with a lighter displacement and other minor changes. All of the Hughes 38 series and the North Star 38 itself are all versions of the basic Sparkman & Stephens' hull design number 1903.

Production
The design was built by North Star Yachts in Canada, after Hughes Boat Works was purchased by U.S. Steel and renamed in 1969. The boat was built from 1971 until 1976. It was replaced by the Hughes 38-3 in 1977 after previous owner Howard Hughes bought the company back.

Design
The North Star 38 is a recreational keelboat, built predominantly of fibreglass, with wood trim. It has a masthead sloop rig; a raked stem; a raised counter, reverse transom; a skeg-mounted rudder and a swept, fixed fin keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel, is fitted with a Universal Atomic 4 gasoline engine for docking and manoeuvring and has a hull speed of .

Emilio Villari. Emilio Villari (25 September 1836 – 20 August 1904) was an Italian experimental physicist and a professor at the University of Bologna and later Naples who contributed to studies on electromagnetism after whom is named the Villari Effect which is used in devices used to measure mechanical stress and strain. He also developed a quadrant electrometer.

Early life 

Villari came from a wealthy family, his father was a lawyer and a younger sibling was Pasquale Villari. Suffering from epileptic seizures from an early age he was privately educated in Naples including in literature under Leopoldo Rodino, math under Achille Sannia and physics from Luigi Palmieri. He then went to the University of Pisa where his brother Pasquale taught. He studied medicine initially but was influenced by Riccardo Felici to shift to physics.

Career 
Villari spent some time in Germany in the laboratory of Gustav Magnus before joining the University of Bologna in 1871 as professor of physics. In 1900 he moved to Naples to succeed Gilberto Govi. In 1873 he examined why alternating current causes greater heat generation in metals than direct current. Villari suggested that this was due to the existence of molecular magnets and their resistance to induced electromagnetism and differed in his theory from that of Maxwell and Kelvin. He examined the expansion of ferromagnetic materials under electromagnetism and discovered the reverse effect as well which is sometimes known as the Villari Effect. The Villari effect is put into application in strain sensors in a wide range of engineering situations. In 1901 he published on the effect of X-rays on the ionizability of air. He constructed electroscopes and observed the effect of (radiation from) pitchblende on discharges. Other experiments were on electrical capacitance, the elasticity of rubber, and the flow of liquids like mercury through tubes. Most of his experimental work was published in the journal Il Nuovo Cimento (1877-1894). Adolfo Bartoli worked on radiation thermodynamics with Villari in Bologna for some time. Augusto Righi worked as an assistant to Villari while Mario Pieri was a student. He was a foreign member of the Royal Society. Villari received the Matteucci Medal for 1884.

Hatice Gunes. Hatice Gunes is a Turkish computer scientist who is Professor of Affective Intelligence & Robotics at the University of Cambridge. Gunes leads the Affective Intelligence & Robotics Lab. Her research considers human robot interactions and the development of sophisticated technologies with emotional intelligence.

Early life and education 
Gunes was an undergraduate student at the Yıldız Technical University. She moved to the University of Technology Sydney for her doctoral research, where she was awarded the Australian Government International Postgraduate Research Scholarship (IPRS) to focus on vision and machine learning based analysis of affective face and upper body behaviour. Her doctoral research showed that affective face and body displays are simultaneous but not strictly synchronous; explicit detection of temporal phases (onset-apex-offset) can improve the accuracy of affect recognition; recognition from fused face and body modalities performs better than that from the face or the body modality alone; and synchronized feature-level fusion achieves better performance than decision-level fusion. She created the Bimodal Face and Body Gesture Database (FABO), a collection of labelled videos of posed, affective face and body displays for automatic analysis of human nonverbal affective behavior. After earning her doctorate, she was appointed an Australian Research Council postdoctoral fellow, and worked on airport and railway security through object human tracking. In 2008, Gunes moved to Imperial College London, where she worked alongside Maja Pantić in the Intelligent Behaviour Understanding Group (iBUG). The project looked to build a dialogue system that can interact with humans via a virtual character.

Research and career 
In 2011, Gunes was appointed a lecturer at Queen Mary University of London. She remained there for four years, becoming an associate professor in 2014. She moved to the University of Cambridge in 2016, where she was promoted to a Professor of Affective Intelligence and Robotics. In 2019, she was awarded an Engineering and Physical Sciences Research Council fellowship, and was appointed a Faculty Fellow of the Alan Turing Institute. Her fellowship considered human–robot interactions and the development of robot emotional intelligence through the study of human-human interactions. She investigated the relationships between humans and their companion robots and looked to design robots with enhanced socio-emotional skills.

Gunes was appointed President of the Association for the Advancement of Affective Computing in 2017. She is interested in how technologies can enhance a sense of wellbeing, through affective VR, autonomous and tele-presence social robotics.

Orthoborate. In inorganic chemistry, an orthoborate is a polyatomic anion with formula  or a salt containing the anion; such as trisodium orthoborate . It is one of several boron oxyanions, or borates.

The name is also used in organic chemistry for the trivalent functional group , or any compound (ester) that contains it, such as triethyl orthoborate .

Structure

The orthoborate ion is known in the solid state, for example, in calcium orthoborate , where it adopts a nearly trigonal planar structure. It is a structural analogue of the carbonate anion , with which it is isoelectronic. Simple bonding theories point to the trigonal planar structure. In terms of valence bond theory, the bonds are formed by using sp2 hybrid orbitals on boron.

Some compounds termed orthoborates do not necessarily contain the trigonal planar ion. For example, gadolinium orthoborate  contains the planar  ion only a high temperatures; otherwise it contains the polyborate anion .

Reactions

Solution in water
When orthoborate salts are dissolved in water, the anion converts mostly to boric acid  and other hydrogen-containing borate anions, mainly tetrahydroxyborate . The reactions of orthoborate in solution are therefore mostly those of these compounds.

In particular, these reactions include the condensation of tetrahydroxoborate with cis-vicinal diols such as mannitol, sorbitol, glucose and glycerol, to form relatively stable anion esters. This reaction is used in analytic chemistry to determine the concentration of borate anions.

Biography
Ni was born in Anshan, Liaoning, in October 1962. After resuming the national college entrance examination, in 1979, he entered the Harbin Institute of Architectural Engineering (now Harbin Institute of Technology), majoring in industrial and civil buildings. 

He joined the Chinese Communist Party (CCP) in July 1983, on the verge of graduation. After graduating in 1983, he was assigned to the Village and Town Construction Department of the Ministry of Construction.

In April 1996, he became assistant mayor of Hefei, capital of east China's Anhui province, and was elevated to vice mayor in August 1999. He was appointed party branch secretary of Anhui Provincial Department of Construction (later reshuffled as Anhui Provincial Department of Housing and Urban-Rural Development) in December 2002, concurrently serving as director since January 2006.

He was recalled to the Ministry of Housing and Urban-Rural Development and appointed director of Housing Reform and Development Division in December 2010. He moved up the ranks to become vice minister in June 2015 and minister in June 2022.

As Housing Minister

In March 2024, as China's property crisis worsened with China Vanke came under pressure to repay its private debts, Ni, in a press briefing, reiterated a stance that homes are "for living in, not for speculation."

In October 2024, China declared its property sector to have "bottomed out" and pledged a funding boost of 4 trillion yuan (562.18 billion USD). During a ministry press conference, Ni emphasized positive signs of recovery noting encouraging home purchase data. He stated that Beijing will increase its loan pool for pre-qualified projects and developers from 2.23 trillion yuan to 4 trillion yuan by year-end.
