HERMES: A Data and Specimens Transporter from the Stratosphere to the Ground—The First Experimental Flight

open access: yesDrones, 2023
Large stratospheric balloons are the easiest access to near space. Large long duration balloons (LDBs) can float in the stratosphere for weeks collecting measurements (e.g., astrophysical or geophysical data) or samples (e.g., contaminants, volcanic ash,

The lithium depletion boundary and the age of NGC 2547 [PDF]

open access: yes, 2003
We present the results of a photometric and spectroscopic survey of cool M dwarf candidates in the young open cluster NGC 2547. Using the 2dF fiber spectrograph, we have searched for the luminosity at which lithium remains unburned in an attempt to ...

ESTUDO BIOQUÍMICO DO POTENCIAL DA MEMBRANA AMNIÓTICA NA FIBROSE HEPÁTICA INDUZIDA EM RATOS

open access: yesRevista UniVap, 2016
A fibrose hepática causada por obstrução do ducto biliar induz alterações tanto na estrutura como na função do fígado, e pode levar a cirrose e insuficiência hepática, quando não tradada. A membrana amniótica humana (MA) devido às suas propriedades anti-

Lateral Distortional Buckling Resistance Predictions of Composite Alveolar Beams: A Review

open access: yesBuildings, 2023
Few studies have investigated the structural behavior of steel-concrete composite alveolar beams in hogging bending regions. Their resistance can be reached by lateral distortional buckling (LDB), coupling LDB and local failure modes, or limit states of ...

Theoretical Examination of the Lithium Depletion Boundary

open access: yes, 2003
We explore the sensitivity in open cluster ages obtained by the lithium depletion boundary (LDB) technique to the stellar model input physics. The LDB age technique is limited to open clusters with ages ranging from 20 to 200 Myr.

Low-Dose Berberine Attenuates the Anti-Breast Cancer Activity of Chemotherapeutic Agents via Induction of Autophagy and Antioxidation

open access: yesDose-Response, 2020
Berberine (BBR), a major active component of Rhizoma coptidis , is one of the most promising agents for breast cancer adjuvant therapy. It is well accepted that BBR could exhibit remarkable anticancer efficacy with few side effects, and when treated with

Changes in Coral Skeleton Growth Recorded by Density Band Stratigraphy, Crystalline Structure, and Hiatuses

open access: yesFrontiers in Marine Science, 2021
Next-generation high resolution brightfield microscopy, x-radiography, and microcomputed tomography (microCT) analyses indicate that coral skeleton high density band (HDB) and low density band (LDB) stratigraphic sequences record dynamic changes in coral

The Caenorhabditis elegans Ldb/NLI/Clim Orthologue ldb-1 Is Required for Neuronal Function

open access: yesDevelopmental Biology, 2000
LIM homeodomain (LIM-HD) and nuclear LIM-only proteins play important roles in a variety of developmental processes in animals. In some cases their activities are modulated by a nuclear LIM binding protein family called Ldb/NLI/Clim. Here we characterize the Ldb/NLI/Clim orthologue ldb-1 of the nematode Caenorhabditis elegans. Two alternatively spliced
