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...

To enhance the decay resistance of bamboo oriented strand board (OSB) products, the strands were dipped in solutions of alkaline copper quat (ACQ) and copper azole (CA) and bonded with phenol formaldehyde resin into two types of OSB panels, i.e., panels with 100% treated strands and those with treated strands only in the face layers. The results indicated that the decay resistance of treated pa...

The focus of this paper is to develop a technique of solving a combined problem of determining Optimum Strata Boundaries (OSB) and Optimum Sample Size (OSS) of each stratum, when the population under study is skewed and the study variable has a Pareto frequency distribution. The problem of determining the OSB is formulated as a Mathematical Programming Problem (MPP) which is then solved by dyna...

The X-ray structures of the ligand free (apo) and the Mg(2+)*o-succinylbenzoate (OSB) product complex of o-succinylbenzoate synthase (OSBS) from Escherichia coli have been solved to 1.65 and 1.77 A resolution, respectively. The structure of apo OSBS was solved by multiple isomorphous replacement in space group P2(1)2(1)2(1); the structure of the complex with Mg(2+)*OSB was solved by molecular r...

To determine the potential of a low cost Irish engineered timber product to replace high cost solid timber for use in bending active structures such as gridshells a single Irish engineered timber product in the form of orientated strand board (OSB) was selected. A comparative study of OSB and solid timber was carried out to determine the optimum properties that make a material suitable for use ...

Creep response of a full-scale floor system fabricated with composite wood I-joists and oriented strand board (OSB sheathing) was measured for 280 days at sustained uniform loads of 20 psf (0.96 kPa). Creep responses of bare I-joists and 3-joist T-beams with OSB sheathing (glued and unglued tongue and groove sheathing joints) were measured under similar load levels and duration. The creep defle...

Network Coding (NC) is a hot topic nowadays. Even though it has proven its applicability to wireless networks, there are still some questions whether network coding is feasible for small devices. To answer this question an implementation of the Partial Network Coding (PNC) buffer scheme is done on a wireless sensor and the results are described within this paper. Originally PNC was presented in...

o-Succinylbenzoate synthase (OSBS) from Escherichia coli, a member of the enolase superfamily, catalyzes an exergonic dehydration reaction in the menaquinone biosynthetic pathway in which 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC) is converted to 4-(2'-carboxyphenyl)-4-oxobutyrate (o-succinylbenzoate or OSB). Our previous structural studies of the Mg(2+).OSB complex establish...

The overall goal of this study is to gain an insight into the load sharing aspect between oriented strand board OSB and gypsum wall board GWB in shear wall assembly during racking load. Sixteen standard 2,440 2,440 mm walls were tested monotonically, in total, out of which 11 Type A were sheathed on both sides OSB on one side and GWB on the other , while five walls were tested without GWB Type ...

A test procedure to simulate and measure the actual behavior of solid and engineered wood products subjected to realistic cyclic moisture loading conditions was carried out at the Institute for Research in Construction (IRC), National Research Council Canada (NRC). The wetting and drying experiments on oriented strand board (OSB), showed that the rate of moisture absorption and the rate of dryi...
