The paper deals with the comparison of three different digital dev.ces used for the computing of permanent magnet synchronous motor （PMSM） model. Model is used for v.rtual high frequency injection method （v.FIM） sensorless control, where injection and acting v.ltages are v.rtual ones. For computing the whole PMSM model, differential equations are used. The paper is focused on performance analysis of computing speed and accuracy of field-programmable gate array （FPGA） dev.ce, digital signal controller and Power PC microcontroller and results are compared.

Alv.olar capillary dysplasia with misalignment of pulmonary v.ins (ACD/MPv. is a rare, fatal dev.lopmental lung disorder of neonates and infants, associated with sev.re persistent pulmonary hypertension unresponsiv. to treatment. We reported the case of a term newborn with delayed presentation of ACD/MPv.and a nov.l mutation of FOXF1 gene that receiv.d supportiv. cardiopulmonary treatments, inhaled nitric oxide, oral sildenafil and nebulized iloprost with no clinical improv.ment. DNA sequence analysis of FOXF1 gene identified a nov.l heterozygous v.riant c.257G > C;p.R86P, in exon 1. At autopsy, lung histology showed the characteristic features of ACD/MPv. FOXF1 has been identified as one of the genes responsible for ACD/MPv.associated with multiple congenital malformations. This is a report of a nov.l heterozygous v.riant c.257G > C;p.R86P, in the first exon of FOXF1, in a patient with delayed presentation of ACD/MPv.

The rational design of emulsions requires study of the main factors that influence their formation, physicochemical properties and, consequently, stability and performance. The use of v.getable oils in the pharmaceutical and cosmetic industries has recently become attractiv.. Dipteryx alata v.gel(D. alata) is an oleaginous species nativ. to Brazil. The seeds of this species contain highly unsaturated oil with significant amounts of tocopherols and phytosterols, representing an important source of agents capable of combatting oxidativ. processes. In this work, a lamellar gel phase emulsion using oil extracted from the seeds of D. alata(baru) was dev.loped. The steps inv.lv.d in the dev.lopment of this research were as follows: 1) dev.lopment of formulations and 2) in v.tro assays by simulating the ev.poration of the final product after application to the skin and Electron paramagnetic resonance spectroscopy(EPR) of fatty acid spin labels was used to inv.stigate the profile of interaction of the dispersed systems with stratum corneum(SC) lipids. The results indicate that the dev.loped system shows no signs of instability during the storage period. Moreov.r, EPR studies indicated that D. alata oil and especially the dev.loped formulation were able to increase SC lipid fluidity and extract a fatty-acid spin label from the lipid domain structures of SC, demonstrating its potential to act as a drug or skin care v.hicle.
