Implementation of a pilot parent-focused physical activity program with Latino families in a Head Start program

Introduction and Background. Physical activity (PA), even at young age, is associated with physical and psychological health. This study determined the feasibility of implementing a parent-led PA intervention and evaluated potential outcomes. Methods. Parent-child pairs from a Head Start center were randomized into intervention (N=20) and control (N=18) groups. All families received a bag of play equipment. Parents completed questionnaires assessing their own and their children’s PA, as well as self-efficacy, social control (SC), and social support (SS) regarding their provision of PA to their children. Parents in the intervention were trained in self-regulatory skills, facilitation of PA, and attended two playdates. Parents rated the playdates, activity sheet and equipment on a 5-point Likert scale. Results. Parents rated the playdates (M=4.9, SD=0.3), the activity sheet (M=4.7, SD=0.7) and the equipment bag (M=5, SD=0.0) highly. Child’s PA, parent’s moderate-to-vigorous PA, total PA, parental efficacy, SC, and SS showed no significant intervention effects. Overall, child and parent PA increased significantly over time (p=.02 for both). Conclusions. The intervention was positively received, with 90% completion rate and high ratings of the intervention materials. Longer interventions with more contact may be needed to influence potential outcomes

Tilapia By-product Hydrolysate Powder In Diets For Nile Tilapia Larvae

This study aimed to evaluate the digestibility of tilapia by-product protein hydrolysate powder (TBHP) from tilapia filleting by-product, and its inclusion in diets for Nile tilapia larvae. In order to determine the apparent digestibility coefficients, two diets were formulated, the reference diet and the test diet (20% of TBHP) and, to evaluate the inclusion, six diets were formulated, which were with 0.0, 2.0; 4.0; 6.0, and 8.0% of TBHP. The apparent digestibility coefficients of crude protein and gross energy were 89.5 and 98.3%, respectively. At levels above 4.0% of inclusion of TBHP, the weight, final length and weight gain were impaired, however, survival rate was higher (p < 0.05). The TBHP can be used in diets for tilapia due to the high digestibility coefficients for crude protein and gross energy. The inclusion of up to 4.0% of TBHP does not affect the reproductive performance and survival rate of Nile tilapia larvae.3911

Algunos conflictos semióticos en la noción de límite en estudiantes de pedagogía

En este trabajo analizamos las respuestas a tareas propuestas sobre la noción de límite a estudiantes de pedagogía de educación media en matemática de un curso de cálculo diferencial. Utilizando herramientas del Enfoque Ontosemiótico, realizamos un análisis de las respuestas, en la relación a la tarea propuesta–estudiante, lo que permitió proponer categorías cognitivas comunes para detectar algunos conflictos semióticos en la introducción de la noción de límite

Algunos conflictos semióticos identificados en la noción de límite

En este trabajo se analiza las respuestas a tareas propuestas sobre la noción de límite de estudiantes de pedagogía de educación media en matemática que cursan la asignatura cálculo diferencial. Por medio de las herramientas teóricas del Enfoque Ontosemiótico (EOS), se realiza un análisis de las respuestas en relación a la respuesta institucional, lo que permitió proponer categorías cognitivas comunes para detectar algunos conflictos semióticos en la introducción de la noción de límite

Production And Spray Drying Of Protein Hydrolyzate Obtained From Tilapia Processing By-products

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)In the last few decades, the offer of by-products obtained from the processing of tilapia (Oreochromis niloticus) has increased, and the need for developing products with high biological and nutritional values for use in animal nutrition motivated this study. Enzymatic hydrolysis of carcass, head and skin of tilapia was performed, as well as the separation of oil, residual solids and soluble proteins by centrifugation at high temperature and the spray drying of the protein fraction. Factorial designs were employed in the assays to evaluate the operating conditions of the spray dryer (inlet and outlet temperatures and flow rate) and the inclusion of drying aid agents (maltodextrin and calcium carbonate). The spray drying showed the best results with air inlet temperature of 190 degrees C, outlet temperature of 90 degrees C, flow rate of 30 L.h(-1) including 10% maltodextrin (mass) in the liquid feed as a drying aid. The final powder recovery was higher than 90% and the physical, chemical and microbiological analyses met the Brazilian legal standards.3818997CNPq [453854/2013-3]Fundacao Araucaria/CAPES [1032/2013, 43234/2014]R.M.

Synthesis Of Novel 2-aryl-3-(2-morpholinoethyl)-1,3-thiazinan-4-ones Via Ultrasound Irradiation

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)This study describes the synthesis of fourteen thiazinanones from a multicomponent reaction of 2-morpholinoehtylamine (as primary amine), arenealdehydes (as carbonyl compound) and the mercaptopropionic acid using both conventional (thermal heating) and ultrasound methodologies. Through thermal heating methodology, the thiazinanones were obtained in 49 to 97% yields for 16 hours and through sonochemistry methodology, the reaction time was reduced for 25 minutes with yields 41 to 88%. The full identification and characterization of unpublished heterocycles were achieved by proton (H-1) and carbon 13 (C-13) nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry and infrared. Some of them were also characterized by elemental analysis.27611091115UFPelFAPERGS [11/2068-7]FAPESP [2013/18203-5]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

As Corporações de Ofício e o Desenvolvimento Industrial das Nanotecnologias: Perspectivas para a Teoria Jurídica da Empresa a Partir dos Compassos do Tempo de François OST

El fenómeno de las oficinas de empresa remonta a la primera forma de organización económica, expansionista jurídica y social. Responsable de la difusión de las normas sociales éticas. Violado la "tradición", el comerciante fue excluido de la sociedad. Con el liberalismo económico y utilitarismo sociales llegó a su fin. La voracidad de la mano invisible no funcionó. La Teoría Jurídica de firma es la "promesa". El desarrollo industrial nanotecnológico es "perdón". El rescate de la tradición dará el norte para el desarrollo, volver a conectar el pasado con el futuro.O fenômeno das corporações de ofícios remonta à primeira forma de organização econômica, jurídica e social de caráter expansionista e empresarial.
