1. Dynamics of a Small Unmanned Aircraft Parachute System
ABSTRACT: Parachute Systems (PS) can be readily used by small Unmanned Aircraft Systems (UAS) for risk mitigation and aircraft recovery. To date there has been limited research into the fundamental dynamics of parachutes at low Reynolds numbers, with existing studies focusing on larger parachutes. An understanding of the dynamics is needed to establish sound

2. A influência de palmares e parachute na coordenação dos nados / Effect of hand paddles and parachutes on swimming coordination
A natação é uma modalidade esportiva que, ao longo dos anos, sofreu modificações, atingindo um alto nível de exigência, o que é refletido nas sessões de treinamentos e nas pesquisas sobre a modalidade. Sendo assim, para otimizar o deslocamento nos nadadores pode-se otimizar a força propulsora. Para isso, pode-se utilizar palmares e parachute. Os pa

3. Efeitos do treinamento de força específico no desempenho de nadadores velocistas treinados com parachute
OBJETIVO: verificar os efeitos do treinamento de força específico no desempenho de nadadores velocistas. METODOLOGIA: dois grupos de nadadores randomizados em treinados sem (TSP, n: 8) e com parachute (TCP, n: 12) foram submetidos a treinamento de 12 semanas (6 x semana; 1 sessão de 2 h/dia), sendo avaliados a força muscular (FMMI); a força específica

4. Cytogenetic analysis of Astylus antis (Perty, 1830) (Coleoptera, Melyridae): Karyotype, heterochromatin and location of ribosomal genes
Cytogenetic analysis of Astylus antis using mitotic and meiotic cells was performed to characterize the haploid and diploid numbers, sex determination system, chromosome morphology, constitutive heterochromatin distribution pattern and chromosomes carrying nucleolus organizer regions (NORs). Analysis of spermatogonial metaphase cells revealed the diploid num

5. Parachute technique for partial penectomy
PURPOSE: Penile carcinoma is a rare but mutilating malignancy. In this context, partial penectomy is the most commonly applied approach for best oncological results. We herein propose a simple modification of the classic technique of partial penectomy, for better cosmetic and functional results. TECHNIQUE: If partial penectomy is indicated, the present techn

6. Parachute and lateral propping reaction in preterm children
Com o objetivo de traçar um perfil clinico-epidemiológico e estabelecer marcos do desenvolvimento neurológico de recém-nascidos prematuros aos 3, 6, 9 e 12 meses de idade corrigida, quanto às reações do paraquedismo e do apoio lateral, foi realizado estudo de coorte não controlado, com enfoque prognóstico. Foram incluídos no estudo recém-nascidos

7. Astylus variegatus (Coleoptera, Melyridae): Cytogenetic study of a population exposed to agrochemical products
In this work we describe the cytogenetic analyses performed in specimens of Astylus variegatus (Germar, 1824) collected in two localities: one area of natural vegetation and one of agricultural crops, where agrochemical products were used. Astylus variegatus had karyotypes with 2n(male) = 16+Xy p and 2n (female) = 16+XXp, with exclusively metacentric chromos

8. C-banding and fluorescent in situ hybridization with rDNA sequences in chromosomes of Cycloneda sanguinea Linnaeus (Coleoptera, Coccinellidae)
The aim of this study was to describe mitotic and meiotic chromosomes of Cycloneda sanguinea using C-banding, fluorescent in situ hybridization (FISH) rDNA probes, and sequential FISH/Ag-NOR staining. The chromosome number was 2n = 18 + XX for females and 2n = 18 + Xy for males. The X chromosome was metacentric and the Y chromosome was very small. During mei

9. Parachute deformity of the tricuspid valve.
A parachute deformity of the tricuspid valve occurred in a heart with atrioventricular concordance, double outlet right ventricle, and straddling mitral valve. Although to the best of our knowledge parachute deformity of the tricuspid valve has not previously been reported, in this case its presence was insignificant in relation to the other lesions.

10. Parachute deformity of the mitral valve
A case of parachute deformity of the mitral valve, a rare congenital form of mitral stenosis characterized by insertion of the chordae tendineae into a single posterior papillary muscle, is described in an 11-year-old girl. The eleven other cases in the English literature are reviewed.
