Benzylideneanilines, the condensation products of benzaldehyde and aniline derivatives, have enjoyed significant success as optical metal ion sensors due to their ability to form stable metal complexes which exhibit distinct spectral features compared to the unbound compound. However, their use in aqueous media is limited by the hydrolytic susceptibility of the C=N moiety. Hence, an in-depth investigation into the hydrolytic degradation mechanism of a series of 2-aminophenol derived Nbenzylideneanilines was conducted wherein molecular modelling techniques were applied to elucidate the “step-by-step” transformation mechanism of these compounds from a fundamental perspective.
The burgeoning of small gourmet chocolate boutiques worldwide serves as a key driver for niche and ultra-niche marketing of cocoa (Theobroma cacao L.), branded as (a) geographical indication (b) estate origin or (c) based on unique genetics. Over 90% of the cacao farms globally, are small with an average size between 2 and 5 hectares and can benefit from supplying to the gourmet boutiques.
A major challenge facing farmers in Portland, Jamaica is dry weather, especially during the optimal growing season from April through August. During this five-month period Portland suffered from severe dry spells during the years 2014, 2015, 2018 and 2020. A second challenge is the damage to crops and land as well as loss of livestock due to tropical storms or hurricanes and the associated flooding. Portland farmers have suffered losses due to an active hurricane season numerous times and most recently in the years 2004, 2005, 2012 and 2020.
Piano grass (Themeda arguens), reputed to have been introduced to Jamaica as packing material in an imported piano1 . There are about 27 varieties of this highly invasive grass/weed worldwide[1] and in Jamaica the species previously identified as Themeda arguens is of concern as it has progressively taken over lawns, pastures and roadsides [1]. The grass is of particular concern to livestock farmers due to its highly invasive and aggressive nature and the concomitant negative effect on livestock productivity, especially during its annual seeding period (November/December – April) [2], when the palatability of the grass diminishes significantly and the seed awns can cause severe damage to the mouth when consumed, and feet of livestock [2], sometimes requiring veterinary intervention.
Numerous organic chemicals, either directly manufactured or formed as byproducts of other processes, are released into the environment. Once there, many cause adverse effects on environmental and human systems. Of particular concern are long-lasting impacts from those organic pollutants that remain in the environment for long periods of time. The development of appropriate management strategies to address this problem requires knowledge of the environmental distributions of these pollutants.
In recent years there has been a resurgence in interest in psychedelic assisted psychotherapy (PAP) [1]. Initial scientific research into the utilization of these compounds were eventually suspended due to concerns related to increasing recreational use of psychedelics and their association with the rise of the “counterculture movement” in the United States [2]. However, the use of psilocybin and other psychedelics have shown promise in the treatment of mental illnesses. The efficacy of this modality of treatment has been demonstrated through clinical trials and other studies in the management of a number of mental illnesses, including some treatment resistant cases [3].
