Small pilot study of ultra-high pressure reverse osmosis technology for treating landfill leachate in Northwest China

open access: yesGongye shui chuli
Landfill leachate has high COD, ammonia nitrogen and conductivity, these complex pollution characteristics make the reverse osmosis treatment load too high, which further leads to the decrease of membrane performance and membrane permeate flux.

Kinetics of fat and protein secretion in dairy cattle, sheep, goats and buffaloes [PDF]

open access: yes, 2003
The negative correlations of fat and protein concentrations and milk yield, existing in all ruminants dairy species (Oftedal, 1984; Mepham, 1987), reflect a deep mechanism regulating the respective kinetics of secretion of carrier (mainly lactose which ...

Projecting Water Yield Amidst Rapid Urbanization: A Case Study of the Taihu Lake Basin

open access: yesLand
Changes in land cover and land use (LULC) can impact water availability by altering the structure and functioning of land ecosystems. Accurately projecting the impacts of LULC on water yield (WY) is of utmost importance for regional landscape management.

Simulation of hydrogen production for mobile fuel cell applications via autothermal reforming of methane [PDF]

open access: yes, 2006
This paper presents a simulation of catalytic autothermal reforming (ATR) of methane (CH4) for hydrogen (H2) production. ATR is essentially an oxidative steam reforming, which combines the exothermic partial oxidation (PO) with the endothermic steam ...

Assessing Climate Change Impacts on Yield of “Dual‐Priority” Water Rights in Carryover Systems at Catchment Scale

open access: yesWater Resources Research
Future water availability is threatened by changes in both climate and water demand. Water rights with differing priorities are an important foundation of demand‐side tools (e.g., buyback, water pricing, and water market) to improve water use efficiency ...

Water-Yield Relationships in Deficit Irrigated Onion

open access: yesTurkish Journal of Agriculture - Food Science and Technology, 2019
This trial was realized in the greenhouses of Uludağ University Yenişehir Vocational School between 2009 and 2010 to investigate effects of water deficit on yield and quality parameters of onion during four crop growth stages. In this trial, fourteen irrigation treatments in four growth periods (establishment, vegetative, yield formation and ripening ...
