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

Large meteoroids belonging to the α-Capricornid meteoroid stream
, 2012 Several objects have been proposed as the parent body of the α-Capricornid meteoroidstream. Among them we can find the short period comets 141P/Machholz and 45P/Honda-Mrkos- Pajdusakova, but also asteroids such as (2101) Adonis, 2002 EX12(=169P/NEAT) and (9162) 1987 OA [1-5]. The debris produced by the fragmentation of the

Meteoroid Engineering Model (MEM) 3: NASAs Newest Meteoroid Model
, 2019 Meteoroid impacts threaten spacecraft and astronauts at all locations within the Solar System. At certain altitudes in low-Earth orbit, orbital debris dominates the risk, but meteoroids are more significant within 250 km of the Earths surface and above ...

Lunar Habitats Protection Against Meteoroid Impact Damage
, 2010 The establishment of human habitats on the Moon and on Mars will require protecting them from the hazards of near-Earth and interplanetary space. in addition to solar radiation, another hazard to be faced by these habitats is the damage that can result ...

Integrative 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

Meteoroid Environment Modeling: the Meteoroid Engineering Model and Shower Forecasting
, 2017 The meteoroid environment is often divided conceptually into meteor showers plus a sporadic background component. The sporadic complex poses the bulk of the risk to spacecraft, but showers can produce significant short-term enhancements of the meteoroid ...
