A Microwave Method for Measuring Moisture Content, Density, and Grain Angle of Wood William L. James, Physicist Forest Products Laboratory, Madison, WI You-Hsin Yen, Graduate Student Ray J. King, Professor of Electronic and Computer Engineering, University of Wisconsin, Madison, WI The attenuation, phase shift and depolarization of a polarized 4.81-gigahertz wave as it is transmitted through a ...

Preliminary notes A laboratory laser beam drying method for corn grain kernels is presented and the corresponding energy transfer is analysed. The proposed drying method enables fast and efficient decrease in grain humidity while preserving grain sprouting. Laser beam was directed to the thin grain layer with powers of 10 kW/m and 20 kW/m. Grains were illuminated from one side during a period o...

Guo, Danping. M.S., Purdue University, May 2015. Kernel and Bulk Density Changes due to Moisture Content, Mechanical Damage, and Insect Damage. Major Professor: Klein Ileleji. Corn (Zea Mays), is one of the major grain crops in the world and moisture content, mechanical damage and insect damage are three factors that affect its quality. The primary goal of this thesis was to investigate the eff...

Vertical movement and distribution of Cryptolestes ferrugineus (Coleoptera: Laemophloeidae) adults in stored wheat and corn were studied in small (0.1 x 0.1 x 1 m) and large (0.6 m diameter and 1.12 m high) columns. The adults were introduced at the top, middle, and bottom of the small columns with a uniform moisture content (wheat: 14.5 +/- 0.1%, corn 13.5 +/- 0.1%, 15.5 +/- 0.1%, and 17.5 +/-...

this experiment was conducted for estimating the effect of row spacing and plant density on soil moisture change, wheat yield and water use efficiency in rainfed condition, using a three replicated randomized complete block design with factorial arrangement at gorgan university of agricultural sciences and natural resources farm in anbare-ololum region in 2008-2009. the treatments that used wer...

One medium-grain rice variety, six long-grain varieties, and two long-grain hybrids, harvested from 13.4% to 26.0% moisture content (MC) from Keiser, Arkansas, Stuttgart, Arkansas, and Alvin, Texas, were used to determine the influence of harvest location and MC on kernel-to-kernel breaking force distributions (BFDs). Harvest moisture content (HMC) affected BFDs, however, a greater influence wa...

Addae-Mensah, Nda-Agyima K.. M.S.A.B.E., Purdue University, May 2014. Quality Changes in Hermetic Stored Corn caused by Fungi and Sitophilus zeamais (Motschulsky). Major Professors: Klein Ileleji and Linda Mason. Hermetic storage has been shown to be effective in controlling insect pests and maintaining grain quality of dry grains at 13% moisture and below. However, the feasibility and use of h...

The occurrence of P. verrucosum and ochratoxin A (OTA) were surveyed for 3 and 4 years, respectively. A total of 250 samples was collected from an average of 30 farms during the 2011, 2012, 2013 and 2014 winter seasons. Most storage bins surveyed were typically 11 m high round bins made of corrugated, galvanized steel, with flat-bottoms and conical roofs. Samples of clumped grain contained the ...

Liquid water sorption in the longitudinal direction in wood samples of Picea abies (L.) Karst. (Norway spruce) was measured with computed tomography (CT) scanning and image processing and then evaluated using multivariate discriminate analysis. The purpose was to determine if there were any differences in liquid water sorption that could be dependent on the vertical position within the tree (0....
