The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine

open access: yesGender &History, EarlyView.
ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...

Hospitaller Revenues, Bourbon Regalism: The Financial Administration of the Grand Priory of Castile and León under an American Parvenu

open access: yesHistory, EarlyView.
Abstract After the vicissitudes of the War of the Spanish Succession (1701–14), the consolidation of the Bourbon Monarchy in early eighteenth‐century Spain allowed Philip V's ministry to implement the so‐called Nueva Planta in his various kingdoms and lordships of the Crown of Aragon, but also in Castile.

Detection of an intergalactic meteor particle with the 6-m telescope

open access: yes, 2007
On July 28, 2006 the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences recorded the spectrum of a faint meteor. We confidently identify the lines of FeI and MgI, OI, NI and molecular-nitrogen N_2 bands.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

open access: yesActa Geologica Sinica - English Edition, EarlyView.
ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt. This study integrates structural analysis and trace element geochemistry of sulphides to elucidate ore‐controlling mechanisms and metallogenic models.

Double-Station Automatic Video Observation of the Meteors

open access: yesAdvances in Astronomy, 2010
The double station observation of the meteors by means of sensitive image intensifier technique started at the Ondrejov Observatory 10 years ago. The sensitivity of such instrumentation allows detection of the meteors down to masses of fractions of gram.

Optical electronics for meteor observations [PDF]

open access: yes
Spectral observations of meteors have been carried out for several years using an optical electronics facility. Interest has centered on faint meteors and their trails in the period of intensive meteor showers. Over 800 meteors were registered during the
