Instructional Models for Course-Based Research Experience (CRE) Teaching (open access)

Instructional Models for Course-Based Research Experience (CRE) Teaching

This article presents a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate course-based research experience (CRE). The study presented here delineated a set of specific instructional practices used by active CRE instructors and modeled the relations between the use of these practices and specified outcomes. The resultant educational models should provide clarification of the ways in which the aims of CRE can be effectively achieved by instructors.

Systematics of the Stonefly Tribe Suwalliini Surdick and Behavioral Studies of Selected Species in the Stonefly Families Chloroperlidae and Perlidae (open access)

Systematics of the Stonefly Tribe Suwalliini Surdick and Behavioral Studies of Selected Species in the Stonefly Families Chloroperlidae and Perlidae

The purpose of this study is to revise the genus Suwallia and to evaluate the potential taxonomic importance of adeagal and other genitalic characters, adult pigment patterns and egg characters. The revision concentrates on western North American species while providing coverage of all species, except Suwallia asiatica Zhiltzova and Lavanidova where only presumed females have been available for study. Communication and mate locating behaviors in adult stoneflies are critical for life cycle completion and species perpetuation. Drumming signals are known for numerous species of Plecoptera, but mate searching patterns and specifically, if or how vibrational communication is utilized for locating mates are virtually unknown for all stonefly species. I conducted field or laboratory studies of three species to elucidate mate searching patterns and how vibrational communication is used for locating mates. The species studied included a bushtopper, Suwallia pallidula (Banks); a ground scrambler, Claassenia sabulosa (Banks); and treetopper, Perlinella drymo (Newman). The "fly-tremulate-search". "rock to rock" and "fly-drum-search" search patterns exhibited by these species are described, as well as how vibrational communication is used for mate finding. Vibrational signal production by tremulation is reported for the first time in Suwallia, and for only the second time Plecoptera.

Pretreatment Optimization of Fiberglass Manufacturing Industrial Wastewater (open access)

Pretreatment Optimization of Fiberglass Manufacturing Industrial Wastewater

Wastewater effluent produced in the fiberglass manufacturing industry contains a significant amount of total suspended solids. Environmental regulations require pretreatment of effluent before it is discharged to the municipal wastewater treatment plant. Chemical precipitation by coagulation and flocculation is the method of pretreatment used at the Vetrotex CertainTeed Corporation (VCT). A treatability study was conducted to determine conditions at which the VCT Wastewater Pretreatment Plant could operate to consistently achieve a total suspended solids concentration ≤ 200-mg/L. Jar tests varied pH, polymer dosage, and ferric sulfate dosage. Total suspended solids and turbidity were measured to evaluate treatment performance. The data were used to determine an optimum set of conditions under project guidelines. Of twelve polymers screened, BPL 594 was selected as the most effective polymer. For cost efficiency in the wastewater pretreatment operation, recommendations suggested that treatment chemical injection be electronically controlled according to turbidity of the treated effluent.
