Legality of cannabis

The legality of cannabis for medical and recreational use varies by country, in terms of its possession and cultivation, how it can be consumed and what medical conditions it can be used for. These policies in most countries are regulated by the United Nations Single Convention on Narcotic Drugs, ratified in 1961, along with the 1971 Convention on Psychotropic Substances and the 1988 Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances; the use of cannabis for recreational purposes is prohibited in most countries. Others have much more severe penalties such as some Asian and Middle Eastern countries where possession of small amounts is punished by imprisonment for several years. Countries that have legalized recreational cannabis are Canada, South Africa, Uruguay. In addition, eleven states and the District of Columbia in the United States and the Australian Capital Territory in Australia have legalized recreational cannabis. Legality varies in subnational jurisdictions when it comes to commercial sale.

A policy of limited enforcement has been adopted in many countries, in particular Spain and the Netherlands where the sale of cannabis is tolerated at licensed establishments. Countries that have legalized the medical use of cannabis include Argentina, Canada, Colombia, Cyprus, Greece, Italy, Lithuania, North Macedonia, the Netherlands, New Zealand, Portugal, Poland and Thailand. Others have more restrictive laws that only allow the use of certain cannabis-derived pharmaceutical drugs, such as Sativex, Marinol, or Epidiolex. In the United States, 33 states and the District of Columbia have legalized the medical use of cannabis, but at the federal level its use remains prohibited for any purpose

Auckland Tuatara

The Auckland Tuatara is a professional baseball team in the Australian Baseball League based in Auckland, New Zealand. They are the only team from New Zealand to compete in the ABL, one of two expansion teams that entered the league in the 2018/19 season. Prior to the team's foundation in 2018, Baseball New Zealand, the country's governing body of the sport of baseball, held talks starting in 2009 regarding the prospects of adding a New Zealand-based team in the Australian Baseball League. In November 2017, the league decided to expand to eight teams beginning in the 2018/19 season, Baseball New Zealand was awarded a spot in the competition. On 26 August 2018, the club's name was announced as the Auckland Tuatara, named after the oldest surviving species endemic to the country. According to one of the team's board members, Brett O'Riley, the tuatara was chosen as the name in order to celebrate the resilience of the ancient reptiles, to raise awareness of New Zealand's commitment to species protection.

The club's colours and navy blue, are representative of the region's marine heritage. The Tuatara played its home games at McLeod Park in Te Atatu South for the 2018/19 season, moved to an expanded QBE Stadium in Albany for the 2019/20 season and beyond. For baseball a section of seating was permanently removed and replaced by an outfield wall, termed The Teal monster; the club's inaugural manager was announced as former MLB pitcher Steve Mintz. Three days before the start of the 2019–2020 season, Tuatara player Ryan Costello was found dead in his sleep by teammates on November 18, 2019. Players wore'RC' on their game jersey for the season in his memory. Australian Baseball League website

Jan D. Achenbach

Jan Drewes Achenbach is a professor emeritus at Northwestern University. Achenbach was born in Leeuwarden, he studied aeronautics at Delft University of Technology, which he finished with a M. Sc. degree in 1959. Thereafter, he went to the United States, Stanford University, where he received his Ph. D. degree in 1962. After working for a year as a preceptor at Columbia University, he was appointed as assistant professor at Northwestern University. Achenbach has developed methods for flaw detection and characterization by using contact transducers, imaging techniques and laser-based ultrasonics, he has developed methods for thin-layer characterization by acoustic microscopy. Work is both analytical and experimental in nature, with extensive cooperation with investigators from other universities and from industrial organizations on theoretical experimental projects. Work in fracture mechanics has been on dynamic fracture, he carries out research on structural acoustics and on the mechanical behavior of composite materials.

Achenbach is the founding editor-in-chief of Wave Motion. He was editor in chief from the journal's establishment in 1979, until 2012. 2012 – ASME Medal by the American Society of Mechanical Engineers 2010 – Theodore von Karman Medal by the American Society of Civil Engineers 2005 – National Medal of Science 2003 – National Medal of Technology 2001 – William Prager Medal by the Society of Engineering Science 1997 – Outstanding Service Award by the American Academy of Mechanics 1996 – McDonnell-Douglas Aerospace Model of Excellence Award by McDonnell-Douglas Aerospace 1992 – Timoshenko Medal by the American Society of Mechanical Engineers 1975 – Curtis W.
