Medical clothes have the primary function of protection. However this function must be correlated with a good comfort experience to the user. The comfort is a very important issue, since professionals are exposed to stress situations that can influence, negatively, their performance work. More specific, thermal comfort plays a crucial role for the best performance of OR medical clothing, involving heat regulation and mass transfer between a clothed body and the environment, once clothing is the interface between body and environment. The aim of this work was to study the behavior of thermal properties of surgical scrub and clean air suits A comparison was made between this two types of clothing using Alambeta equipment, for stationary thermal properties and a Thermal Manikin, to allow the analysis of dynamic thermal properties, such as heat flux and thermal insulation. It was found that clothing thermal insulation is statistically different, showing that the difference between suits may will perceived by the user. [ABSTRACT FROM AUTHOR]

In the this work it is analyzed how pertinent is the academic plan of the Food Science and Technology career at the University of Havana as a contribution of the cuban government to the strategy of guarantee Food and Nutritional Security. It is analyzed how the present Plan remains the emphasis in this concept. It is presented a view over the principal concepts like Study Objective; Professional Fields and Professional Functions as well as academic disciplines which have a total or partial contribution to the professional performance in the specific field of Food and Nutritional Security. It may be conclude that in the academic plan (Plan D), as minimum, 49% of total time assigned has a direct relation with the concept. [ABSTRACT FROM AUTHOR]

The sterilization of medical products is one of the principal applications of the radiations, which at commercial scale were applied to half-filled of the years 50. In 70 years, the average of radio sterilized materials was less than 10%, but at the beginning of the years 90 ascended at more than the 70%, with tendency at the increase for dry raw materials, principally. The objective of the present work was determine the dose of sterility for the batch of Alginato of Sodium, Quitosana and Apafill-BP, in being solid, studied in order to achieve the sterilization of the same with a Sterility Assurance Level of 10-6. It was carried out the bacteriostatic and fungistatic effect determination, previously, and the determination of the bioburden by means ISO 11737-1. The sterilised dose was calculated by means of mathematical expression that relates the bioburden of the product, the D10 value of the most resistant micro organism at the product and the Sterility Assurance Level. It was gotten that the products didn't have bacteriostatic neither fungistatic effects. The sterilized dose for each batch of product was less than 25 kGy for each one. The verification dose experiment was successful; all the irradiated samples were sterile. It was gotten that the studied products could be sterilized gamma by means of the employment of the radiations achieving the sterility with a level of insurance of 1: 1000000. [ABSTRACT FROM AUTHOR]

Center for Technological Applications and Nuclear Development (CEADEN) demonstrated the ability to assimilate new Internet of Things technologies by developing a wireless environmental monitoring system. The system is based on a wireless network of sensors, using free hardware and software electronic platforms such as Arduino and LoRa wireless communication interface. It enabled the continuous measurement of environmental parameters covering large areas within the National Museum of Fine Arts. The long experience of the microbiology laboratory facilitated the creation of a procedure for microbial sampling, carried out in parallel with environmental measurements. The combination of environmental monitoring with microbiological sampling showed that they can be tools that help art conservators to preserve cultural heritage. [ABSTRACT FROM AUTHOR]

The healing, pain relieving effect and antimicrobial properties of amnion grafts have been reported in the scientific literature since the beginning of the 20thcentury. Amniotic membrane (AM) is ideal for clinical and advanced therapies. It facilitates the growth, adhesion, differentiation, and migration of epithelial cells. It is an ideal biocompatible, biological scaffold for regenerative medicine applications and advances therapies. A validated methodology for the production of radio sterilized amniotic membrane as a medical device has been implemented at the Centre for Applied Technologies and Nuclear Development (CEADEN) for more than 20 years. According to actual Cuban standards, this product is a class III medical devise, because of its origin. It has-been employed in several ophthalmological and dermatological pathologies, with promising results. Due to its outstanding properties, AM is highly in demand, allowing a faster recovery of patients. In addition, it is relatively easy to obtain with low-cost production, transforming it into a valuable alternative to other products. Recently, CEADEN participated in project supported by the International Atomic Energy Agency (IAEA) focused on scaffolds and tissue engineering. In addition, it is developing a research project financed by the Agency for Nuclear Energy and Advanced Technologies (AENTA) with the aim of obtain and apply AM as a biocompatible scaffold.
