Rapid reaction optimization by robust and economical quantitative benchtop F NMR spectroscopy.

The instrumental analysis of reaction mixtures is usually the rate-determining step in the optimization of chemical processes. Traditionally, reactions are analyzed by gas chromatography, HPLC or quantitative NMR spectroscopy on high-field spectrometers. However, chromatographic methods require elaborate work-up and calibration protocols, and high-field NMR spectrometers are expensive to purchase and operate.

COMPARATIVE HYGIENIC ASSESSMENT OF THE POTENTIAL DIQUAT HAZARD TO THE POPULATION WHEN CONSUMING AGRICULTURAL CROPS TREATED WITH THE REGLONE AIR 200 SL FORMULATION USING DIFFERENT APPLICATION TECHNOLOGIES (UAV, AERIAL, HIGH-CLEARANCE ROD SPRAYER TREATMENT).

Objective: The aim: Assessment of the hazard to the population when consuming treated crops by using different technologies.

Patients And Methods: Materials and methods: Unmanned aerial vehicle XAG XPlanet 2020 equipped with four rotating rotors, which allows to keep in the air a 20-liter tank was used for spraying field; a manned aircraft AN-2 aggregated with a serial sprayer. High-clearance rod treatment of sunflower and rapeseed crops was carried out by using a PLA MAP II 2010 tractor.

Update of Takotsubo cardiomyopathy: Present experience and outlook for the future.

Takotsubo cardiomyopathy (TTS) has become a recognised clinical entity since the Japanese scientist Sato first described it in 1990. Despite an increasing number of confirmed cases, especially during the COVID-19 pandemic, its pathophysiology remains incompletely understood, and decision-making differs in the diagnosis and treatment. In addition, it is not evident whether a significant increase in TTS is due to better understanding among practitioners and widespread access to coronary angiography, or if it is a reflection of an actual increase in incidence.

COMPARATIVE HYGIENIC ASSESSMENT OF PESTICIDES BEHAVIOR IN SOIL IN INTENSIVE GRAIN FARMING TECHNOLOGIES.

Objective: The aim: Was the comparative hygienic evaluation of the pesticide behavior in the soil after application on cereals.
