The experimental measurement and modeling of liquid chemical agent spread and sorption on a porous substrate are described. Experimental results with the nerve agent O-ethyl S-(2-diisopropylaminoethyl) methylphosphonothiolate (VX) demonstrate that the wetted imprint volume increases, even after the sessile drop volume is exhausted. This indicates the wetted imprint is only partially saturated, ...

Longitudinal connectivity is a fundamental characteristic of rivers that can be disrupted by natural and anthropogenic processes. Dams are significant disruptions to streams. Over 2,000,000 low-head dams (<7.6 m high) fragment United States rivers. Despite potential adverse impacts of these ubiquitous disturbances, the spatial impacts of low-head dams on geomorphology and ecology are largely un...

This study aimed to examine the effects of varying levels deficit irrigation applied through partial root drying (PRD) and conventional on some parameters cucumber plant such as fresh dried biomass, stem diameter, number leaf, fruit length, weight, water soluble dry matter (WSDM). Seven treatments (DI75, APRD75, FPRD75, DI50, APRD50, FPRD50) were examined together with control treatment (FULL)....

By the current paper, lift force that is an important characteristic of a planing hull is calculated. To accomplish this task, Morabito’s mathematical model that has been previously derived for prediction of total pressure distribution on planing hulls is utilized. These equations are not restricted to any specific mean wetted length and can be used for planing hulls with large value of mean we...

Carbon Capture & Storage (CCS) is one of the various methods that can be used to reduce the carbon footprint of the energy sector. This paper focuses on the absorption of CO2 from flue gas using packed columns, whose efficiency is highly dependent on the structure of the liquid films within the column. To study the characteristics of liquid films a CFD solver, OpenFOAM is utilised to solve two-...

A method for measurement of dimensions of platy particles of exfoliating, or delaminating, materials, such as clays, in aqueous suspensions in situ is proposed. Equivalent spherical diameter (esd), measured by many common methods, depends more on the major (lateral) dimension of a particle, while it is less sensitive to changes of the particle thickness. Addition of the second method, results o...

Eolian transport of biomass from ephemerally wetted soils, associated with summer glacial meltwater runoffs and lake edges, to low-productivity areas of the Antarctic Dry Valleys (DV) has been postulated to be an important source of organic matter (fixed nitrogen and fixed carbon) to the entire DV ecosystem. However, descriptions and identification of the microbial members responsible for N(2) ...

To evaluate methods for detection of genital human papillomavirus (HPV) DNA in men, samples were obtained from 3 consecutive groups of 10 men attending a sexually transmitted disease clinic by use of (1) a saline-wetted Dacron swab alone, (2) a saline-wetted cytobrush, or (3) emery paper (600A-grit Wetordry Tri-M-ite; 3M) abrasion followed by a saline-wetted Dacron swab. By use of a polymerase ...

Adjuvants have been used to improve pesticide application efficiency and effectiveness for many years. However, knowledge on quantitative reactions of adjuvant-amended pesticide droplets on Article Request Page http://asae.frymulti.com/azdez.asp?JID=5&AID=29662&CID=pitt2010&T=1[12/28/2010 12:43:57 PM] foliage is lacking. Evaporation rate and wetted area of 500 μm droplets with four different ad...

In this paper, nanoscale wetting on groove-patterned surfaces is thoroughly studied using molecular dynamics simulations. The results are compared with Wenzel's and Cassie's predictions to determine whether these continuum theories are still valid at the nanoscale for both hydrophobic and hydrophilic types of surfaces when the droplet size is comparable to the groove size. A system with a liqui...
