Abstract A convenient and efficient solvent-free, facile, one-pot three-component graphene oxide catalysed approach 09gi shades eq has been described for the synthesis of chromeno-[4,3-b]quinolin-6-one derivatives from 4-hydroxycoumarin with aldehydes and aromatic amines.Graphene oxide (GO) has proved to be a new class of heterogeneous carbocatalys

Inflammation is a protective response of the body to an irritant.When an inflammatory response occurs, immune cells are recruited luau thank you cards to the injury, eliminating the irritation.The excessive inflammatory response can cause harm to the organism.Inflammation has been found to contribute to cervical cancer if there is a problem with th

In this article, we propose the detection of crowd anomalies through the extraction of information 53-264817 in the form of time series in video format using a multimodal approach.Through pattern recognition algorithms and segmentation, informative measures of the number of people and image occupancy are extracted at regular intervals, which are th

The eutrophication of aquatic ecosystems caused by rapid human urbanization has led to an increased production of potentially hazardous bacterial populations, known as blooms.One of the most notorious forms of these aquatic blooms are cyanobacteria, which in sufficiently large quantities can pose a hazard to human health through ingestion or prolon

Cynara cardunculus (Cc) is a multipurpose species; beyond its use in southwestern European cuisine, it is also used for the production of solid biofuel, seed oil, biodiesel, paper pulp and cheese, as well as animal feed.In addition, Cc has a long tradition of use in folk medicine as a diuretic and liver protector.The value of this species as a sour
