International Journal of Biological Engineering and Agriculture During the agricultural year 2020–2021, an experiment was carried out in clay soil at the College of Agriculture / University of Basrah to investigate the impact of the elements under investigation on the mean weight diameter (MWD) in clay soil. The factors under investigation were as follows: the solid sprinkler irrigation system's operating pressure,

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Designing Nonwovens to Meet Pore Size Specifications [PDF]
Journal of Engineered Fibers and Fabrics, 2007 New nonwovens applications in areas such as filtration require a media designed to particular pore size specifications in the 3 to 20 micron range. The purpose of this work was to develop a basis by which to design and construct a fabric with given pore ...

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Placental Structure in Preterm Birth Among HIV-Positive Versus HIV-Negative Women in Kenya. [PDF]
, 2019 BackgroundPreterm birth (PTB) is a major cause of infant morbidity and mortality in developing countries. Recent data suggest that in addition to Human Immunodeficiency Virus (HIV) infection, use of antiretroviral therapy (ART) increases the risk of PTB.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
