THE INFLUENCE OF STEAM ON SOME CHEMICAL SOIL PROPERTIES - REVIEW

Soil forms a thing mantle over the Eart¢s surface and acts as the interface between the atmosphere and lithosphere, the outermost shell of the Earth. It is a multiphase system, consisting of mineral material, plant roots, water and gases, and organic matter at various stages of decay (Bardgett R., 2005,). Soil temperature influence plant nutrients uptake through a multitude of chemical, physical and biological processes that intercat over wide range of spatial and temporal scales (BassiriRad H, 2005) Steaming is traditionally used in glasshouses to sterilise the soil and control both weeds and diseases prior to crop establishment. Steam is applied under pressure beneath metal pans forced down onto freshly formed beds for periods of 3-8 minutes. The steam raises the soil temperature to 70-100 °C killing most weed seeds to a depth of at least 10 cm. The increase in inorganic substances in soil due to steaming means an increased fertility as more nutrients become available for the plant (Bond et al., 2003

Utilization of a Mobile Application for Motor Skill Evaluation in Children

[Abstract] The detection of needs in educational reinforcement must be done in the early stages of childhood during primary education to improve the acquisition of motor skills. An adequate early intervention can solve some detected difficulties, thus contributing to children’s motor progress and mitigating possible deficiencies such as weak motor coordination. In this work, we present a mobile application (app) that allows physiotherapists to design activities for the evaluation of motor skills. These activities can be adapted to the child’s progress and the corresponding reinforcement needs. We tested the app with children from ages 6 to 12, corresponding to the six primary school grades. The results show that these children did not have notable motor difficulties, although children in lower primary school years showed a higher level of error in movement precision. The results allow us to establish reference values for a future comparison with collectives with motor difficulties.This work has been funded by the Xunta de Galicia (ED431G2019/01), the Agencia Estatal de Investigación of Spain (TEC2016-75067-C4-1-R) and ERDF funds of the EU (AEI/FEDER, UE)Xunta de Galicia; ED431G2019/0

Mobile Application for Analysing the Development of Motor Skills in Children

[Abstract] This work presents a mobile application to complement and reinforce the specific physical activities in children through training prior to such activities and monitoring their progress after it. This experiment has been developed on a healthy population of children from an education centre in the area of A Coruña. The results show increasing errors for lower primary school years, as expected, and also strongly dependent on the motor path type or characteristic. Therefore, this tool will be suitable for use with children affected by motor coordination difficulties.Xunta de Galicia; ED431G2019/01Agencia Estatal de Investigación de España; TEC2016-75067-C4-1-

Pharmacokinetic analysis of topotecan after superselective ophthalmic artery infusion and periocular administration in a porcine mode

Purpose: To characterize the vitreous and plasma pharmacokinetics of topotecan after ophthalmic artery infusion (OAI) subsequent to superselective artery catheterization and to compare it with periocular injection (POI). Methods: The ophthalmic artery of 4 pigs was catheterized and 1 mg of topotecan infused over a period of 30 minutes. The contralateral eye was subsequently used for administering topotecan by POI. Serial vitreous specimens were obtained by microdialysis and plasma samples collected and assayed for total and lactone topotecan. Results: Maximum total topotecan concentration in the vitreous (median, range) was significantly higher after OAI compared with POI (131.8 ng/mL [112.9–138.7] vs. 13.6 ng/mL [5.5–15.3], respectively; P , 0.005). Median vitreous exposure calculated as area under the curve for total topotecan attained after OAI was significantly higher than after POI (299.8 nghour/mL [247.6–347.2] and 48.9 nghour/mL [11.8–63.4], respectively; P , 0.05). The vitreous to plasma exposure ratio was 29 after OAI and 3.4 after POI. Systemic exposure for total topotecan was low after both modalities of administration, with a trend to be lower after OAI compared with POI (10.6 nghour/mL [6.8–13.4] vs. 18.7 nghour/mL [6.3–21.7]; P = 0.54). Conclusion: Superselective OAI resulted in significantly higher vitreous concentrations and exposure and a trend toward lower systemic exposure than POI.Fil: Schaiquevich, Paula Susana.
