Diâmetro médio predominante de partículas do solo

Revista Brasileira de Ciência do Solo, 2000
Apresenta-se um modelo empírico capaz de representar, analiticamente, a curva de distribuição textural acumulada de partículas de um solo e, a partir desse modelo, obter uma expressão que fornece o diâmetro médio predominante de partículas (∅m), que ...

Determinação de diâmetros médios em micrometria I - Obtenção da ortogonalidade entre o maior e o menor diâmetro, através de ocular micrométrica simples

Semina: Ciências Exatas e Tecnológicas, 2004
  Na determinação de diâmetros médios, a ortogonalidade entre os diâmetros medidos - maior e menor — é requisito essencial. Em se tratando de estruturas microscópicas, tais tomadas de medida são comumente efetuadas através de ocular micrométrica e ...

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

Journal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

Fetal neurosonography and infant neurobehavior following conception by assisted reproductive technology with fresh or frozen embryo transfer

Ultrasound in Obstetrics &Gynecology, Volume 60, Issue 5, Page 646-656, November 2022., 2022
ABSTRACT Objective We aimed to explore fetal cortical brain development by neurosonography in fetuses conceived by assisted reproductive technology (ART), including frozen and fresh embryo transfer (ET), compared with those conceived spontaneously (SC), and to investigate its association with infant neurobehavior at 12 months of age. Methods This was a

Brachycephaly in French bulldogs and pugs is associated with narrow ear canals

Veterinary Dermatology, Volume 33, Issue 3, Page 214-e60, June 2022., 2022
Background Brachycephalic dog breeds have multiple skull malformations which may lead to anatomical changes in the external auditory canal. It is our frequent observation that in the otoscopic examination of the external ear in these breeds we are unable to visualise the tympanic membrane as a consequence of extreme narrowing of the proximal ear canal.

Determinação de diâmetros médios em micrometria. I - Obtenção da ortogonalidade entre o maior e o menor diâmetro, através de ocular micrométrica simples

Semina: Ciências Sociais e Humanas, 1984
Orthogonality between major and minor measuring diameters is an essential requirement when mean diameter determination has to be performed. For the microscopic dimensions, however, simple micrometer eyepieces and its conventional usage don't provide that

Novo método para calcular o diâmetro médio de agregados de solos

Revista Brasileira de Ciência do Solo, 1997
Ao calcular o diâmetro médio ponderado (DMP) ou o diâmetro médio geométrico (DMG) de uma amostra de solo, ponderam-se o diâmetro médio aritmético (no caso do DMP) ou o logarítmico (no caso do DMG) de cada classe pela massa de agregados nela retida.

Transanal total mesorectal excision for locally advanced middle–low rectal cancers

BJS Open, Volume 4, Issue 2, Page 268-273, April 2020., 2020
A prospective study was undertaken of 38 patients with mid–low locally advanced rectal cancer who underwent rectal resection with transanal total mesorectal excision (TaTME) procedure. No conversions, abdominoperineal resections or deaths occurred. TaTME is safe and effective for patients with mid–low locally advanced rectal cancer.
