Women increasingly earn advanced degrees in science, technology, and mathematics (STEM), yet remain underrepresented among STEM faculty. Much of the existing research on this underrepresentation relies on “chilly climate” and “pipeline” theoretical models to explain this phenomenon. However, the extent to which these models follow women’s actual career pathways has been undertheorized. Further,...
Oceanic islands host a high proportion of the world’s endemic species. Many such species are at risk of extinction owing to habitat degradation and loss, biological invasions and other threats, but little is known about the effects of climate change on island native biodiversity. The Azorean archipelago provides a unique opportunity to study species-climatechange relationships. We used ensemble...
In the 1730s, Austrian Netherlands (eighteenth century Belgium) faced devastating effects of Great shipworm epidemic. Shipworms are marine wood scavenging molluscs that use their shells to eat way into submerged wood. Due changing environmental conditions (temperature, salinity, …) at time, population exploded along West-European coast. Within a few years wooden flood protection structures prot...
Wheat (Triticumaestivum L.) is a primary staple food crop that supports more than third of the world's population and Asia's main food. Abiotic stressors have an impact on wheat production all over world. A hydroponic research was carried out to investigate effects various salinity levels. i.e 1.5, 5, 10 15 ds/m different cultivars (Aas-11, Gold-16, Johar-16, 1711, 1712, 1713, 1718, 1725, 1754 ...
In Vienna, the tradition of clinical teaching began with Anton de Haen’s introduction newly established educational approach in Buergerspital 1754. second half 18th century, at medical faculties contributed to shift power relationships between doctors and patients. The gaze that doctor patient directed towards each other regulated patients’ as well physicians’ behavior setting hospital medicine...
Introduction: In a 1754 publication, Discussion plus particulière de diverses manières d’elever l’eau par le moyen des pompes avec grand avantage (Very detailed explanation of the different methods raising water through pumps with greatest effectiveness), Leonhard Euler (1707–1783) made extensive use concept mechanical power in estimates needed to raise waters piston pumps, by means natural for...
Este artículo se propone analizar paralelamente las reformas inquisitoriales impulsadas por el papa Benedicto XIV dentro de su estado territorial y enfrentamiento que la Santa Sede sostuvo contemporáneamente con los estados italianos Nápoles Toscana, donde tras cambio dinástico decretaron una serie medidas jurisdiccionalistas dirigidas a acabar presencia realidad extranjera —como fue Inquisició...
We propose a phonon-assisted tunnelling model for explanation of conductivity dependence on temperature and temperature-dependent I-V characteristics in deoxyribonucleic acid (DNA) molecules. The capability of this model for explanation of conductivity peculiarities in DNA is illustrated by comparison of the temperature dependent I-V data extracted from some articles with tunnelling rate depend...
