Exploratory Data Analysis in Cotton Quality Management.

Factor analysis is suitable for analyzing interrelationships among a large number of variables and for explaining these variables in terms of common underlying dimensions. A preliminary study on exploratory data analysis in cotton quality management applied factor analysis to a database comprising values of fiber micronaire, length, unifo..

A Review of Yield and Quality Trends and Components in American Upland Cotton.

A review of upland cotton production and quality in the United States a addresses yield trends; yield components, including gravimetrics and energetics; fiber quality trends; and fiber differentiation and development. Increases in the productive potential of the plant or in the number of seeds per unit of land surface were the primary cau..

Technology's Role in Least-Cost Cotton System.

The cotton industry in the San Joaquin Valley introduced the global positioning system and inertial navigation system for the automatic steering of tractors and other agricultural vehicles in 2000, reducing capital expenditures and variable input costs. These vehicles can receive subinch differential global positioning system signals from..

Influence of Stick Machines on Turnout and Quality of Stripper Cotton.

Researchers investigated the effects of stick machine use at the cotton gin on lint turnout and high volume instrument (HVI) properties. An experiment replicated four harvesting and ginning treatments four times in a randomized complete block experiment. Analysis of variance procedures and differences among treatment means separated by th..

Preliminary Theoretical Aalysis of Lint Cleaning.

Researchers investigated if Baker's mathematical relationships for predicting lint waste and cleaning efficiency, developed in 1977, remained valid for modern cotton varieties. Experimental results confirmed the relationships established by the equations, but indicated that such production parameters as variety and location reduced their ..

Preliminary Results from Moisture Addition during Ginning.

Researchers investigated whether significant differences in measured lint moisture content can be achieved after ginning and lint cleaning by conditioning the seed cotton with moist air. An experiment used equipment common to the second stage of drying in the gin to humidify seed cotton. Higher lint moisture levels before and after the li..

Consolidated Up-Pacing Universal Denisty Bale Press.

Consolidated Cotton Gin Company Limited's new Up-Packing bale press exceeds capacities of 60 bales per hour and is available in both universal and high density models. A review of machine design and operations focuses on durability, capacity, and efficiency. The company installed four of these presses in cotton gins in Australia and Texas..

Fiber Properties of Selected Cotton Lines Obtained by Mutagenesis.

An investigation into the macrostructure and microstructure of cotton fibers from selected lines obtained by mutagenesis exposed imbibed seed to a 3 percent by volume concentration of ethyl methanesulfonate and examined the physical properties of four mutant lines, a parent variety, and a control fiber. Researchers replicated the mutant l..

On-Line Measuring Technology for Cotton Characterization during Processing.

A study examined online testing methods for evaluating cotton raw materials prior to spinning. Researchers identified technologies applicable to the development of online systems for testing foreign matter, vegetable content, stickiness, and fiber fineness, but could not identify systems adaptable to online measurement of such properties ..

Analysis of Cotton Genes for the Antifungal Protein Osmotin.

Osmotins form pores in fungal membranes that lead to osmotic rupture and destruction of the fungal cells. A study of the chromosomal arrangement, gene organization, and regulation of expression of cotton genes for the antifungal protein characterized two cotton genes and a cDNA clone for osmotin. Physical mapping determined that the cotto..
