Oil contamination of ecologically sensitive aquifer systems is a major global environmental problem. Depending on their availability, there is a trend to seek sorbent materials based on natural fibers, for their high adsorption capacity and biodegradability. The objective of this work was to obtain a sorbent material, by carbonizing sugarcane bagasse chemically modified to clean the water contaminated by oil. Tests were carried out to determine the sorption capacity of the carbonized material as a type II sorbent according to ASTM method F 726-17. The optimal particle size for which the sorption capacity was greater, was above 2.0 mm. The sorbent obtained was tested on water contaminated with crude oil, and a comparative evaluation was made between this material and a commercially existing one. As a result of the experiments, very similar values were obtained between the properties of both sorbent materials. Thus, it is concluded that the carbonized bagasse material can be used as hydrocarbon sorbent material.

Delirium is a neuropsychiatric syndrome characterized by acute onset of decits in attention and in multiple aspects of cognition. The prevalence of delirium varies considerably by patient group and setting, tending to be more common in hospitalized older adults or the critically ill. Three phenotypes of delirium are recognized depending on psychomotor activity (hyperactive, hypoactive, mixed). Its diagnosis is based on the criteria established in the DSM V, however we have diagnostic tools used in clinical practice such as 4A, CAM and ICDSC. The pharmacological management of delirium is still a matter of debate, treatments with antipsychotic drugs have been shown to reduce motor activity, but they do not seem to affect the dura
