Competency Based Training to Facilitate Improved Quality Interaction Between Parents and Their Handicapped Infants and Preschoolers

A widely accepted characteristic of early intervention programs for handicapped infants and young children is the active involvement of the child\u27s parents. Although the actual extent of parental involvement varies with programs, typically parents are assuming the role of instructor or presenter of developmentally based activities seeking to improve the skill levels of their developmentally delayed children. Simeonsson, Cooper and Scheiner, (1932) reviewed 27 programs focusing on intervention with biologically impaired infants and young children. Seventy percent of those programs specified a role for parents within the intervention for their children. The value of parent involvement is thought to be supported by this trend in early intervention programs

Scientific Opinion on the safety and efficacy of iodine compounds (E2) as feed additives for all animal species: calcium iodate anhydrous, based on a dossier submitted by Calibre Europe SPRL/BVBA

Calcium iodate anhydrous is considered a safe source of iodine for all animal species/categories when used up to the currently authorised maximum content of total iodine in complete feed, with the exception of horses and dogs, for which maximum tolerated levels are 3 and 4 mg I/kg complete feed, respectively. The limited data available on iodine tolerance in cats support a provisional tolerated level of 5 mg I/kg complete feed. Exposure of consumers was calculated in two scenarios applying the currently authorised maximum iodine contents in feed and reduced contents. The iodine content of food of animal origin, if produced taking account of the currently authorised maximum content of iodine in feed, would represent a substantial risk to high consumers. The risk would originate primarily from the consumption of milk and to a minor extent from eggs. The UL for adults (600 µg/day) and for toddlers (200 µg/day) would be exceeded by a factor of 2 and 4, respectively. If the authorised maximum iodine concentrations in feed for dairy cows and laying hens were reduced to 2 and 3 mg I/kg feed, respectively, the exposure of adult consumers would be below the UL. However, iodine intake in high-consuming toddlers would remain above the UL (1.6-fold). Calcium iodate is considered as irritant to the eye, skin and respiratory tract, and a dermal sensitiser. The exposure by inhalation should be avoided. The use of calcium iodate in animal nutrition is not expected to pose a risk to the environment. Calcium iodate is efficacious to meet animal iodine requirements. The FEEDAP Panel recommends that the maximum iodine contents in complete feed be reduced as follows: dairy cows and minor dairy ruminants, 2 mg I/kg; laying hens, 3 mg I/kg; horses, 3 mg I/kg; dogs, 4 mg I/kg; cats, 5 mg I/kg

CFD investigation of gas-solids flow in a new fluidized catalyst cooler

In our previous work, a new concept of annular catalyst cooler (ACC) was proposed and validated experimentally, which showed that an internal circulation of solids could be formed by using two gas distributors and both hydrodynamics and heat transfer could be largely improved. The current work simulated detailed hydrodynamics of gas-solids flow to advance our understanding of the ACC by using the two-fluid model. The influences of effective particle diameter dp⁎ and specularity coefficient φ were examined and compared with experimental data. Optimum values of dp⁎ = 170 μm and φ = 0.3 were determined and used in the simulations. Detailed hydrodynamics of gas-solids flow were then obtained, and the influential parameters were examined. The results showed that the proper selection of the ratio of gas velocities and the position of the heat transfer tube were needed to form a stable internal solids circulation in the ACC. The ACC had a combined hydrodynamic feature of up-flow and down-flow catalyst coolers with bigger solids volume fraction and smaller particle resident time, which are beneficial for improving the heat transfer between solids and wall

Ossification of the femur in thyroxine-treated tadpoles of Rana pipiens

Tadpoles of Rana pipiens at Taylor-Kollros stage IX were treated by immersion in a thyroxine solution at a concentration of 6.25 x 10-8 M. Hindlimbs developed precociously, and alizarin-stained specimens showed that treatment with thyroxine induced accelerated ossification of limb bones.Light microscopy of thick Epon sections showed that cartilage and perichondrium were beginning to organize in the femur of normal animals at stage IX and had become separated by a narrow zone of osteoid matrix by stage XI. After 4 days of exposure to thyroxine, inner perichondrial cells had enlarged to become osteoblasts bordering a prominent zone of osteoid matrix. By 9 days of treatment some inner osteoblasts were entirely surrounded by bone matrix and thus had become osteocytes.Electron microscopy revealed that rough endoplasmic reticulum began to accumulate in osteoblasts by the second day of treatment. Fusion of collagen fibrils was observed in the osteoid matrix of a specimen treated for 5 days. Deposition of hydroxyapatite crystals along collagen protofibrils in scattered mineralization sites began after 6 days of treatment. Mineralized sites grew and became confluent, so that by 9 days the lower two-thirds of the bone matrix was almost completely mineralized. Enlarged mineralization sites at 9 days usually were organized with collagen protofibrils in the interior and hydroxyapatite crystals clustered around the periphery of the mineralizing mass.Thyroxine appears to stimulate differentiation of osteoblasts from perichondrial cells. The hormone may stimulate osteoblasts to secrete depolymerases which prepare osteoid matrix for mineralization along collagen fibrils.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32873/1/0000251.pd
