Young adult sleep quality is reported to be compromised in the literature with shortened sleep intervals, daytime napping, excessive daytime sleepiness and excessive wakeups. The description of young adult sleep quality commonly includes the rationale that the independent schedule of the young adults coupled with their preferred social schedule, work and academic schedules leaves the planning for sleep to last place. Despite mentation and memory reductions with sleep deprivation secondary to poor sleep quality documented in young adults, the poor sleep quality prevails. This study is focused on the elements of arousal during a young adult’s day that may predispose them to elevated activation and difficulty relaxing sufficiently to fall asleep. It was hypothesized that light exposure was elevated in young adults with poor sleep quality. Light exposure in terms of overhead bright lights in classrooms and laboratories of the academic environment, bright light in terms of video monitors/TVs/tablets/phone exposure is sufficiently stimulating to cause cognitive activation was light exposure.

The use of systems theory to attempt to determine which ＂place in La Mancha＂ was the one whose name Cervantes could not quite recall in his universal novel, appears to be ordained to change certain attitudes towards science held in Cervanfine literature. The reason： after four centuries of literary analysis, systemic methodology has proven able to identify the famous ＂place＂ with acceptable accuracy. Nonetheless, certain reasonable doubts persist around the suitability of a strictly scientific analysis of literature. In light of those doubts, the present article aims primarily to facilitate critique both of the systemic approach adopted and its outcome.

Ifirst met Dr. Andrew V Schally （PhD, MDhc （Multi）, DSc, Distinguished Medical Research Scientist, U.S. Department of Veterans Affairs Professor of Pathology and Department of Medicine, Miller School of Medicine, University of Miami, Miami, Florida, USA） many years ago, probably around the beginning of the 1990＇s in one of his visits to Mexico City （Figure 1）. He has many friends in my country since some of the investigations that led to the development of the LHRH agonists were made in a couple of Mexican hospitals in collaboration with some outstanding Mexican physicians that I will mention later. In that time, I was the head of the Department of Urology of the Mexican National Cancer Institute and our Director, Dr. Jaime de la Garza, invited him for a meeting. I was surprised by his humbleness, intelligence and easy going personality, in spite of being a Nobel Prize scientist.

The effect of mine tailings and sewage sludge was evaluated on sorption, desorption, availability and distribution of copper in two soils, one high （sandy soil） and one low in copper （clay soil）. In both soils contaminated by mine tailings the copper sorption capacity and the affinity of the substrate for the metal decreased substantially compared to the uncontaminated soils, however, the sorption remained always high in the clay soil substrates. In the substrates with sandy soil, the high Cu content and lower clay content were determining factors in the lower magnitude of the sorption. Similarly, metal desorption was closely related to these two parameters, and it was higher in clay soil with lower pH. In general, the application of sewage sludge favored the sorption of Cu in soils contaminated and uncontaminated with mine tailings, and in all cases desorption decreased, an effect that remained for at least 30 days. Simple extraction of Cu with CaCl2 and diethylenetriaminepentaacetic acid gave contradictory results, so a careful choice of the procedure is required, depending on the level of metal in the soil and on the acting principle of the extracting agent. In that relation, more complete information on the changes in the metal forms was obtained by application of the sequential extraction procedure proposed by the European Community Bureau of Reference.
