Authorial Voice, Implied Audiences and the Drafting of the 1988 AIDS National Mailing
Dr. Veeder analyzes changes throughout many drafts of the 1988 ANM and finds that the process of negotiated drafting contributed to its success. She also concludes that risk communicators should focus attention on audience needs rather than competing truth claims
Nickel/tin coating protects threaded fasteners in corrosive environment
Threaded fasteners used in corrosive environments are plated with electroless nickel and electroplated, over the nickel, with tin. This provides a corrosion-resistant coating for the fasteners
Improved pH buffering agent for sodium hypochlorite
Sodium citrate/citric acid was found to be an effective buffer for pH control when used with sodium hypochlorite. The mixture does not corrode aluminum. The buffer appears to form a type of conversion coating that may provide corrosion-resistant properties to aluminum in other applications
For Alfred and Learning to Grieve
Learning to Grieve is a poem about a life long attempt to be present to a father who is absent
Utilization of Electrodeionization to Separate and Concentrate Cellobionic and Gluconic Acid
Biofuel production is currently an expensive and inefficient process with many drawbacks. It is water and land intensive, competes with food production, and requires large energy inputs decreasing its relative sustainability. This paper explores the use of electrodeionization (EDI) to improve the biofuel process by separating and concentrating large, organic sugar acids that are important materials for the production of bioethanol. An EDI device was assembled for the purpose of separating and concentrating gluconic, cellobionic and lactobionic acid. Several trials were conducted and samples were analyzed to determine the success of this experiment. The results for the separation and concentration of gluconate were slightly successful, seeing a complete depletion of gluconate in the dilute stream and an increase from 0 g/L to 0.92 g/L of gluconate in the concentrate stream. It is hypothesized that gluconate was lost to the rinse streams, since there is about 2 g/L of gluconate unaccounted for. The results from the lactobionic acid trial were inconclusive due to equipment failures and contamination of samples. Future steps will be taken to improve the overall process of electrodeionization, and figure out how different combinations of important variables can achieve the greatest level of separation and concentration of large molecules

Editor\u27s Introduction to the Survive and Thrive Poetry Issue: Not Therapy but Transformation
The place of poetry in the Humanities and Health is at once obvious and complex. It is obvious because historically poetry has always been a part of healing and of finding a balanced life. It is a part of a community’s social fabric. This issue of our Journal is an exploration of a community of writers, poetry, and healing
