27 We investigate the interannual variability over 2003-2007 of different hydrological parameters in 28 the Amazon river basin: vertically-integrated water storage from the GRACE space gravimetry 29 mission, surface water level over the Amazon River and its tributaries from in situ gauges, and 30 precipitation. We analyze the spatio-temporal evolution of total water storage from GRACE and 31 in...

BACKGROUND Human papillomavirus (HPV) self-sampling (self-HPV) is valuable in cervical cancer screening. HPV testing is usually performed on physician-collected cervical smears stored in liquid-based medium. Dry filters and swabs are an alternative. We evaluated the adequacy of self-HPV using two dry storage and transport devices, the FTA cartridge and swab. METHODS A total of 130 women perfo...

Abstract Seed banks play an important role in determining the spatial and temporal distribution of halophytes salt marshes. We tested ability native Spartina maritima invasive S. densiflora spikelets to disperse by flotation on water with different salinity concentrations, longevity spikelet viability relative environmental conditions including dry or wet storage at low moderate temperatures, a...

In order to study the damage mechanism of fissure-grouted rocks in abandoned mine pumped storage, uniaxial compression tests were conducted using rock specimens after dry and wet cycles. Additionally, acoustic emission sensors used track specimens. The results demonstrate a negative correlation between peak strength elastic modulus linear decrease wave velocity mechanical characteristics fractu...

The natural drying of fuelwood is a common practice to improve its quality and increase the efficiency in biomass-based energy supply chain. objective this work was analyze effect seasons on physical chemical properties wood logs stored piles for purposes. Eucalyptus urophylla were two periods 160 days each throughout year, autumn–winter (dry season) spring–summer (rainy season). During 320 day...

in this study, a single layer sliced potato was dried using an infrared lamp heating under vacuum over three levels of radiant power including 100, 150 and 200 w, three slices thickness 1, 2 and 3 mm and the absolute pressure of 20, 80, 140 and 760 mmhg. samples were dried in triplicate to achieve 6% moisture content (wet based) which is suitable for long-term storage. drying rate was monitored...

Shale gas and oil are significant unconventional energy resources in the United States. Because of their low porosity and permeability, as well as the complex pore systems in organic rich shale formations, their petrophysical properties are not fully understood. Further, it is well known that wettability influences many aspects of reservoir characteristics, especially hydrocarbon storage and re...

In modern conditions of vegetable oil processing, the issues improving quality and safety refined oils remain relevant. It has been noted that most effective one is complex or complete refining oils, which ensures removal main groups related substances by traditional improved methods. The complexity organization technology associated with accompanying oxidation at certain stages a decrease in t...

alpha-amylase activity of wheat flour is one of the important factors to determine its suitability for baguette bread making. in this study, setareh flour (81% extraction rate) was procured from six flourmills situated in six climatically different provinces. ph, moisture, ash, wet gluten and alpha-amylase activity tests were applied on flour samples and showed that the alpha-amylase activity i...
