The effect of herbicides, pesticides, and fertilizers on the optical properties of water

A reflectometer accessory for a spectrophotometer was designed and constructed in our laboratory. Using distilled water as the reflectance standard, the reflectometer was used to measure relative specular reflectance of 0.5M aqueous solutions of K2SO4 and NH4H2PO4 in the 2-12m wavelength region and for 1M (NH2)2CO in the 2-20m wavelength region for infrared radiant flux incident at about 70 degrees and linearly polarized perpendicular to the plane of incidence. Absolute reflectances of the solutions were computed for 70 degrees angle of incidence by using the relative reflectance measurements, one of the Fresnel equations, and the optical constants of water. The optical constants of the aqueous solutions were then computed by applying a Kramers-Kronig phase-shift dispersion analysis to the absolute reflectance spectra. The report provides a description of the instrumentation and the experimental procedures for making the measurements. The relative reflectances, absolute reflectances, and optical constants are presented in graphical form in the text and are tabulated in Appendix I. Spectral signatures characteristic of the solutes are discussed in the text. In addition, further investigations of the optical constants of distilled water were made in that they are related to the investigations of aqueous solutions. The work on distilled water was accomplished in cooperation with Dr. Dudley Williams at Kansas State University. A reprint describing the work is presented in Appendix I.Project # A-030-MO Agreement # 14-31-0001-302

Pothole Reporting System

The purpose of this project is to create a pothole detection device that can be attached to the underside of a commercial vehicle. Potholes cost motorists around 6.4 billion dollars annually, thus demonstrating the need for a system to aid with the detection and reporting of potholes. The four systems we needed to consider for the implementation of this project were the power system, the sensing system, the data processing system, and the reporting and logging system. Power pulled from the vehicle will enable the sensors and data processing module. The data processing module will analyze the readings from the sensors and output pothole data to the logging and reporting system. The logging and reporting system, located on an android mobile device, will store the pothole locations on a cloud server

Infrared reflectance measurements of Missouri waters for water quality applications

Students supported: 2 studentsThe relative specular reflectance of laboratory solutions of 3.0 M Sulfuric Acid and 0.5 M Sodium Nitrate was measured in the 2.0 - 20-[mu]m wavelength region of the infrared. The relative specular reflectance of natural samples of (1) acid mine drainage taken from a ditch leading from the Peabody Mark Twain Mine to Hinkson Creek; (2) surface water runoff from an agricultural test plot which had received a 314 lb/acre application of nitrate fertilizer; and (3) an oil sample from the Mexico, Missouri oil release into the Salt River was measured in the same spectral region. The data was collected using a Perkin Elmer E-14 spectrophotometer and a reflectometer consisting of a Cassegrain unit which collimated the radiant flux to about 18 mrad divergence, a sample holder and a Cassegrain condenser for focusing the radiant flux, reflected by the sample, onto the entrance slit of the monochromator. The angle of incidence was 70 degrees. The index of refraction, extinction coefficient and phase difference spectrum throughout the 2-20-[mu]m wavelength region was determined for the mine drainage, fuel oil, sulfuric acid, sodium nitrate and nitrate runoff samples using the relative reflectance measurements, the optical constants of distilled water and an algorithm for Kramers-Kronig analysis. The absolute reflectance spectrum of the alluvium and loess was determined using the relative reflectance measurements, the optical constants of distilled water and the Cauchy equation for reflectance. It is very desirable to make water quality measurements remotely. However before such measurements can be taken the characteristic manner in which aqueous solutions reflect electromagnetic radiation (in the optical properties) must be known. Thus the results obtained from this research are a part of a much larger goal to determine water quality remotely.Project # A-063-MO Agreement # 14-31-0001-382

Peran money attitudes terhadap financial well-being dengan financial stress sebagai mediator pada mahasiswa rantau di Surabaya

Objektif: Pengelolaan keuangan yang baik pada kehidupan mahasiswa rantau akan dapat berdampak pada financial well-being. Hipotesis dari penelitian ini adalah financial stress dapat berperan sebagai mediator pada hubungan antara money attitudes terhadap financial well-being. Metode: Responden pada penelitian ini adalah mahasiswa rantau yang tinggal di Surabaya berusia 17-22 tahun dan berjumlah 267 responden. Teknik pengambilan sampel menggunakan accidental sampling. Metode analisis data menggunakan process hayes model 4. Temuan: Hasil penelitian ini menjelaskan bahwa financial stress dapat berperan sebagai mediator (parsial) dengan nilai negatif, dimana aspek power prestige dan distrust dalam money attitudes berhubungan positif dengan financial well-being. Kesimpulan: Hal ini menjelaskan bahwa mahasiswa rantau menganggap uang sebagai simbol kesuksesan, dapat memberikan kesan yang baik bagi orang lain, dan menimbulkan financial well-being serta tidak mengalami financial stress. Selain itu, kondisi ini akan sangat berdampak pada nilai akademik dan kesehatan mental para mahasiswa rantau jika mereka salah dalam mengelola keuangannya
