been hindered by a declining supply of farm labor (Taylor et al. 2012), generating interest among growers in methods to reduce labor requirements for thinning, weeding, irrigating and harvesting (Fennimore et al. 2010; 2014). Thinning lettuce is particularly labor intensive, and most lettuce fields in California are hand-thinned (manually thinned). Automated lettuce thinners that use machine vi...

Materials and Methods: All the reagents were received from Sigma Aldrich Chemical Co. and used without further purification. Solvents were purchased from commercial sources and purified by reported protocol.1 Spectroscopy grade solvents were used for physical studies. 1H NMR and 13C NMR experiments were done on a Bruker DPX-400 MHz and 500 MHz NMR machine and all the data were calibrated agains...

This Review provides a general understanding of paper spray-MS, including the methodology and theory associated with a number of different related applications. This method has become a direct sampling/ionization method for mass spectrometric analysis at ambient conditions and, as a result, it has greatly simplified and increased the speed of mass-spectrum analysis. It has now become an increas...

The current study focuses on comprehensive fuel spray modeling and its effects on chamber acoustics in combustion dynamics simulations. The fuel spray is modeled using an Eulerian-Lagrangian approach describing the atomizer internal flow, primary atomization, and secondary atomization processes. To anchor the fuel spray model, a series of experiments has been conducted on the fuel atomizer with...

Robust and accurate control of secondary cooling is vital to the successful operation of any caster and the production of high quality products. This is especially important in thin slab casters, because high casting speed and a tight machine radius often requires carefully-prescribed temperature profiles to avoid various cracking problems. This can be achieved only by successful control of the...

The objective of this study is taken to realize pesticide precision spray of fruit trees and the other crops and reduce the deposition losses outside the canopy when the real time sensing technology was used in the pesticide target spray. In this paper the Pesticide solution deposition distribution experiments were conducted with two different volume median diameter (VMD) hollow cone nozzles fi...

Piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. Consequently, the aim of this study was to improve the dissolution of piroxicam. Microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...

Delay Tolerant Networks (DTN) are mobile ad-hoc networks in which connections are often disruptive or discontinuous. Data forwarding using an appropriate routing strategy is a highly confronting issue in such networks. The traditional ad-hoc routing protocols which require end-to-end connectivity fail to function here due to frequent occurrences of network partitions. Spray and Wait (SaW) routi...

The aim of this study was to develop a user-friendly model for spray drying that can aid in the development of a pharmaceutical product, by shifting from a trial-and-error towards a quality-by-design approach. To achieve this, a spray dryer model was developed in commercial and open source spreadsheet software. The output of the model was first fitted to the experimental output of a Büchi B-290...
