Numerous drift reduction adjuvants and spray deposition aids are available to applicators of crop production and protection chemicals. Performance of many of the newly introduced drift control adjuvants has not been well documented for aerial application. Since there are no product labeling or efficacy regulations for these adjuvants, applicators must rely on experience or information in the te...

CONTEXT Chronic pain in patients with advanced cancer poses a serious clinical challenge. The Δ9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray (U.S. Adopted Name, nabiximols; Sativex(®)) is a novel cannabinoid formulation currently undergoing investigation as an adjuvant therapy for this treatment group. OBJECTIVES This follow-up study investigated the long-term safety and tol...

OBJECTIVE To investigate the influence of maintenance spray on resin bonding to dentin. MATERIALS AND METHODS The crown of extracted, caries-free human molars was transversally sectioned with a model trimmer to prepare the dentin surfaces from mid-coronal sound dentin, and then uniformly abraded with #600 silicon carbide paper. The dentin surfaces were randomly divided into three groups: oil-...

Airborne particle release during the spray application of coatings was analyzed in the nanometre and micrometre size range. In order to represent realistic conditions of domestic and handcraft use, the spray application was performed using two types of commercial propellant spray cans and a manual gravity spray gun. Four different types of coatings doped with three kinds of metal-oxide tracer n...

This study was designed to prospectively evaluate the role of nebulized hyaluronic acid (HA) administered for 10 days as treatment for patients with rhinitis medicamentosa (RM). RM is a pathological condition of the nasal mucosa induced by prolonged, excessive or improper use of topical decongestants. It is characterized by persistent nasal congestion that can lead the patient to increase the f...

The present study constitutes a crucial step towards the development of a CAD based intelligent spray quetiching system capable of optimizing the mechanical properties (strength, hardness) of agehardenable aluminum alloys. The quenching of an L-shaped aluminum alloy with multiple, partially overlapping spray nozzles was successfully modeled using the finite element method. Spray heat transfer c...

We present a comprehensive look at a sample of bear spray incidents that occurred in Alaska, USA, from 1985 to 2006. We analyzed 83 bear spray incidents involving brown bears (Ursus arctos; 61 cases, 74%), black bears (Ursus americanus; 20 cases, 24%), and polar bears (Ursus maritimus; 2 cases, 2%). Of the 72 cases where persons sprayed bears to defend themselves, 50 (69%) involved brown bears,...

OBJECTIVE The study was conducted to compare povidone-iodine spray and traditional scrub-paint techniques in reducing abdominal wall bacteria during preoperative preparation. STUDY DESIGN Sixty patients scheduled to undergo vaginal surgery were recruited for study. Cultures of the abdominal skin were performed before and after preparation with two techniques: A traditional 5-minute iodophor s...
