Cytogenetic studies in fishes of the genera Hassar, Platydoras and Opsodoras (Doradidae, Siluriformes) from Jarí and Xingú Rivers, Brazil

Genetics and Molecular Biology, 2008
We studied the karyotypes of Hassar cf. orestis and an undescribed Hassar species from the Jarí River and Opsodoras ternetzi, H. orestis and Platydoras cf. costatus from the Xingú River, all with 2n = 58.

Regional recaptures of bats (Chiroptera, Vespertilionidae) ringed in Eastern Ukraine

Zoodiversity, 2020
Bats are volant and highly mobile mammals that could cover up to 2000 km seasonally (one-way migration). But the level of mobility among different roosts sites in a breeding season, and among breeding areas and hibernation sites is poorly studied.

Expressly Fabricated Molar Tube Bases: Enhanced Adhesion [PDF]

Journal of Clinical and Diagnostic Research, 2014
Clinicians, Orthodontists and their patients’ parents often expect the best results in the shortest time span possible. Orthodontic bonding of molar tubes has been an acceptable risk in a modern era of refined biomaterials and instrumentation.

On the origin of shear banding instability in metallic glasses [PDF]

, 2009
To uncover the physical origin of shear-banding instability in metallic glass (MG), a theoretical description of thermo-mechanical deformation of MG undergoing one-dimensional simple shearing is presented.

Onset and Direction of Shear Banding Instability in Metallic Glasses [PDF]

, 2014
The shear banding instability occurs as the homogenous deformation in metallic glasses (MGs) develops to a critical point, at which the discontinuity in deformation rate is incipient across nano-scale shear bands.

Basic Mechanical Behaviors And Mechanics Of Shear Banding In Bmgs [PDF]

, 2008
In this paper, some basic mechanical behaviors of bulk metallic glasses (BMGs) were discussed. It can be found from the discussions that the mechanical behaviors of BMGs are mainly due to the formation and operation of shear bands in BMGs.

Stray Light Artifacts in Imagery from the Landsat 8 Thermal Infrared Sensor

Remote Sensing, 2014
The Thermal Infrared Sensor (TIRS) has been collecting imagery of the Earth since its launch aboard Landsat 8 in early 2013. In many respects, TIRS has been exceeding its performance requirements on orbit, particularly in terms of noise and stability ...

Peculiarities of the present structure of the Bug granulite complex developed within the Middle Bug area and its partitioning into series and suits

Геофизический журнал, 2022
The Gaivoron-Zavalie site and the Golovanevsk suture zone (GSZ) of the Bug mining region (BMR) in the Middle Bug region have been a «testing ground» for studying the structure and stratigraphy of the Early Precambrian complexes of the USh for many years.

An index of shear banding susceptibility of metallic glasses [PDF]

, 2016
By virtue of instability analysis, an index of shear banding susceptibility of metallic glasses (MGs): the critical strain localization factor to initiate an embryonic shear band:chi = gamma(b)/gamma(m) (gamma(b) shear strain in the embryonic shear band ...
