An assembly is disclosed for mounting a pH probe in a flowing solution, such as a sanitary sewer line, which prevents the sensitive glass portion of the probe from becoming coated with grease, oil, and other contaminants, whereby the probe gives reliable pH indication over an extended period of time. The pH probe assembly utilizes a special filter media and a timed back-rinse feature for flushing clear surface contaminants of the filter. The flushing liquid is of a known pH and is utilized to check performance of the probe.

This report has been organized into three sections for ease of review. Section A - Air Resources covers data collected by the 100-foot tower between September and December 1980. Section B - Water Resources covers data collected since the last Quarterly Report. Section C - Aquatic Biology covers data collected since January 1981. Laboratory analysis results of all water samples show no significant changes from previous sample have occurred. The alluvial wells did exhibit slightly higher concentrations of phenols. Presently no baseline record exists for these wells to establish the normal levels of phenols in the alluvial ground water. Laboratory analysis of all sampling locations are presented in Appendix B. Aquatic biology covers data collected during the initial two aquatic biology field sampling trips of 1981. Benthic invertebrates, periphyton algae, and a fishery survey was conducted. Stream observations indicate that the stream habitat has remained unchanged since the August 1980 field visit. (ATT)

A series of measurement is reported that were conducted to evaluate the amount of radiation present in the Fermilab Collider tunnel under different circumstances. Also to be determined is the effect of radiation on scintillators, phototubes, and their electronics, possible damage to drift chamber wires due to high counting rates and possible damage to the drift chamber electronics. Background and resulting trigger rates are evaluated and the effect of local shielding is studied. Results of radiation measurements made during beam-on operation are presented. The detectors used include: two arrays of LiF crystal dosemeters, three scintillation counter telescopes, a modified ion chamber, and six sample pieces of Bicron plastic scintillators. (LEW)

Weekly report of the Texas Crop and Livestock Reporting Service on turkey poult numbers in Texas and compared with other states. It includes compiled statistics across six consecutive weeks during two years for turkey eggs set and poults hatched.

Weekly report of the Texas Crop and Livestock Reporting Service on broiler chick numbers in Texas and compared with other states. It includes compiled statistics across six consecutive weeks, from the week ending May 4 to the week ending June 8, during 1984 and 1985 for broiler eggs set, chicks hatched, and chicks placed.

Recently, measurements in the SPS show that the coherent tune shift in the horizontal direction has positive values whereas that in the vertical direction has negative ones. Thus the existence of negative transverse impedance gets confirmed in a real machine. This stimulates us to start a new round of systematic studies on this interesting phenomenon. The results obtained from our computer simulations are presented in this note. Our simulations demonstrate that the negative transverse impedance may appear when the rotational symmetry embedded in a discontinuity is broken, and that the geometries that we have studies may be the source of the positive horizontal tune shift measured in the SPS.

Gluon emission and the transverse momentum (p/sub t/) of partons confined in nucleons were studied using deep-inelastic charged-current neutrino-nucleon interactions. For this analysis we use the flow of hadronic energy in the azimuthal direction around the momentum transfer referenced from the neutrino-muon scattering plane. A five standard deviation asymmetry was found. Analysis of this asymmetry indicates a (p/sub t/) of 0.35 +- 0.12 GeV/c if QCD corrections are included, and 0.56 +- 0.05 GeV/c if they are excluded. Some evidence was also observed for x dependence in p/sub t/. Data were taken at Fermilab in 1982 using a 200 ton (fiducial mass) fine grained calorimeter and a dichromatic neutrino beam.
