Abstract Recommendations for shop cleaning and priming practices are broken down into seven categories: methods of surface preparation, methods of application, workmanship, supervision, inspection, priming, and fabrication. Surface preparation methods discussed include solvent cleaning, hand cleaning, power tool cleaning, flame cleaning, brush-off blast cleaning, commercial blast cleaning, white metal blast cleaning, and pickling. Application methods considered include brush, spray, hot spray, airless spray, roller, and dip. 5.9.1, 1.7.1, 5.4.7

INTRODUCTION: Kinesio tape (KT) is an emerging tool in paediatric physiotherapy. A small body of research suggests KT is efficacious with some children, but clinical guidelines are not yet available. The aim of this study was to gather physiotherapists’ practices and experiences using KT with children. The focus was on why, where, how, and how long physiotherapists use KT with children, and the outcomes they observe, to guide future experimental research. METHOD: Nine Australian physiotherapists, each with at least two years of experience using KT with children, were recruited. All nine physiotherapists completed a largely open-ended online survey, and three of these physiotherapists participated in a brief follow-up telephone interview. Basic content analysis was conducted. RESULTS: The physiotherapists’ practices and experience with KT largely related to four themes: (1) taping for muscle activation; (2) gait and posture outcomes; (3) child tolerance limiting effectiveness; and (4) inconsistent application methods and treatment durations. CONCLUSION: Physiotherapists in this study used KT to serve a variety of purposes, it was mainly considered beneficial for improving gait and posture. However, there was little agreement regarding how to apply it, for how long, and the exact nature of its benefits. Empirical research is also lacking on these questions. The effectiveness of KT as an adjunct therapy for improving children’s posture and gait warrants further investigation. Research comparing specific taping application methods and durations will be valuable in guiding physiotherapists’ practice.

This study aimed to estimate the virulence of an indigenous Beauveria bassiana on all developmental stages of two indigenous coccinellids; Coccinella undecimpunctata and Hippodamia variegata through three application methods; direct spray, contact method, and feeding on aphids treated with the fungus (ingestion). Also, indirect effect on all developmental stages resulted from 1st larval instar treated with these application methods. All treatments were done with a concentration of 1 × 105 which was recommended in previous studies for different aphid species with a control of 0.02% Tween 80 (v/v). The mortality of 1st larval instar of both H. variegata and C. undecimpunctata and pupal stage of C. undecimpunctata were significantly increased with spray method only. Also, contact method achieved significantly higher mortality on 1st larval instar of C. undecimpunctata only. Regard to indirect effect, except of mortality of 1st larval instar of both predators and 2nd larval instar of H. variegata, other developmental instars/stages of both predators were not affected by B. bassiana through the three tested application methods in the mortality, duration, survival, cumulative survival male and female longevity, and fecundity. Therefore, both tested predatory coccinellids could be compatible with this indigenous isolate of B. bassiana where, in general, there are no negative effects of the fungus on both predators.

Weed control in reduced-tillage corn (Zea maysL. ‘Pioneer 3732′) with butylate [S-ethyl bis(2-methylpropyl) carbamothioate] and EPTC (S-ethyl dipropyl carbarnothioate) was not reduced when these herbicides were applied jointly with dry or liquid fertilizer. In most cases, application with fertilizer resulted in weed control similar to that observed when the herbicide was applied in water at 285 L/ha. Butylate applied as a granular formulation also gave weed control similar to the spray at 285 L/ha. Application in 95 L/ha of water consistently resulted in reduced weed control. Corn injury was not greatly influenced by application method, and differences in corn yield appeared to be due to differences in weed control. Growth chamber bioassays indicated that both butylate and EPTC dissipated more rapidly when applied in 95 L/ha of water than the other application methods, which may explain differences in weed control observed in the field.
