Direct integrals and spectral averaging
A one parameter family of selfadjoint operators gives rise to a corresponding
direct integral. We show how to use the Putnam Kato theorem to obtain a new
method for the proof of a spectral averaging result
Structural, optical and nanomechanical properties of (1 1 1) oriented nanocrystalline ZnTe thin films
Structural, optical and nanomechanical properties of nanocrystalline Zinc Telluride (ZnTe) films
of thickness upto 10 microns deposited at room temperature on borosilicate glass substrates are reported.
X-ray diffraction patterns reveal that the films were preferentially oriented along the (1 1 1) direction.
The maximum refractive index of the films was 2.74 at a wavelength of 2000 nm. The optical band gap
showed strong thickness dependence. The average film hardness and Young’s modulus obtained from loaddisplacement
curves and analyzed by Oliver-Pharr method were 4 and 70 GPa respectively. Hardness of
(1 1 1) oriented ZnTe thin films exhibited almost 5 times higher value than bulk. The studies show clearly
that the hardness increases with decreasing indentation size, for indents between 30 and 300 nm in depth
indicating the existence of indentation size effect. The coefficient of friction for these films as obtained from
the nanoscratch test was ∼0.4.Financial support

Influence of Cost Share and EQIP Incentive Payments on Adoptions of Best Management Practices by Louisiana Dairy Farmers
Adoption of best management practices (BMPs) minimizes the negative externalities created by the manure by-product of milk production. Logistic regression procedure was used to understand the impact of socioeconomic attributes of Louisiana dairy farmers on BMP adoption decision relative to the cost share and incentive payment.Farm Management,
Factors Influencing and Steps Leading to the Adoption of Best Management Practices by Louisiana Dairy Farmers
A logistic regression procedure was used to assess the impact of socioeconomic attributes on the best management practices (BMPs) adoption decision by Louisiana dairy farmers relative to cost-share and fixed incentive payments. Analysis of the steps in the BMP adoption decision process indicated visits between producers and the U.S. Department of Agriculture–Natural Resource Conservation Service significantly increase likelihood of BMP adoption. Producer willingness-to-pay results indicate that marginal increases in dairy BMP adoption and associated improvement in environmental quality require increased technical and financial assistance.best management practices, bootstrap, cost-share, manure, steps in BMP adoption, Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety, Q16, Q25, Q53,
Willingness to Participate in Dairy Programs to Reduce Manure Related Problems in Louisiana's Major Dairy Production Region
Logistic and tobit models were used to understand the factors affecting dairy program participation and stated bid values by respondents. Results indicated that past participation is the key variable in regression. Bootstrap result confirms that most of the estimated parameters fall within the range of bootstrap confidence interval.Livestock Production/Industries,
