Mycotoxins contaminate crops worldwide and play a role in animal health and performance. Multiple mycotoxins may co-occur which may increase the impact on the animal. To assess the multiple mycotoxin profile of corn (Zea mays), we conducted a 7-year survey of new crop corn grain and silage in the United States. A total of 711 grain and 1117 silage samples were collected between 2013 and 2019 and analyzed for the simultaneous presence of 35 mycotoxins using ultra-performance liquid chromatography–tandem mass spectrometry. The measured mean number of mycotoxins per sample were 4.8 (grain) and 5.2 (silage), ranging from 0 to 13. Fusaric acid (FA) was most frequently detected in 78.1 and 93.8% of grains and silages, respectively, followed by deoxynivalenol (DON) in 75.7 and 88.2% of samples. Fumonisin B1 (FB1), fumonisin B2 and 15-acetyl-deoxynivalenol (15ADON) followed. The greatest (p < 0.05) co-occurrence was between FA and DON in 59.1% of grains and 82.7% of silages, followed by FA with FB1, DON with 15ADON, and FA with 15ADON. Although many samples had lower mycotoxin concentrations, 1.6% (grain) and 7.9% (silage) of tested samples had DON ≥ 5000 µg/kg. Fumonisins were detected ≥ 10,000 µg/kg in 9.6 and 3.9% of grain and silage samples, respectively. Concentrations in grain varied by year for eight mycotoxin groups (p < 0.05), while all 10 groups showed yearly variations in silage. Our survey suggest that multiple mycotoxins frequently co-occur in corn grain and silage in the Unites States, and some of the more prevalent mycotoxins are those that may not be routinely analyzed (i.e., FA and 15ADON). Assessment of multiple mycotoxins should be considered when developing management programs.

This article explores the role of Japanese merchants within American art and collecting circles and analyzes the ways in which the construction of “Asianness” and, in particular, “Japaneseness” became intertwined with the classification of Asian art. In order to reconstitute the market for high art and to create their own positionalities as legitimate cultural intermediaries, Asian art dealers such as Bunkio Matsuki (1867–1940) and Sadajiro Yamanaka (1866–1936) used their connections to Japan as cultural capital. Ultimately, their experiences illuminate the complexities of the reconceptualization of ethnic–racial identities through the lens of aesthetic discourses.

This study investigated the perceptions of piano performance programs in higher education from current collegiate students and faculty members’ perspectives in China and the United States. Participants were from representative university-level institutions in the U.S. ( n = 41) and China ( n = 130). They were sent a questionnaire concerning (a) the factors that motivate students to pursue a piano performance degree, (b) the most important educational practices in their programs, (c) the most challenging tasks the students encounter, (d) students’ career goal, and (e) faculty members’ suggestions for prospective students and opinions on improving the piano performance programs. A summary of students and faculty members’ perceptions were outlined and the comparison between the two countries were explored. It is encouraging that not only students gave careful attention toward the applied lessons and performance opportunities in their studies, but also that a large percentage of the students believed they received excellent advice regarding practice strategies and artistry in their applied lessons in both countries. Most of the faculty participants in both countries expressed positive attitudes regarding the piano performance programs in their universities. By providing statistically significant data, this study provides a comprehensive vision for institutions to continue establishing piano programs.

This paper utilizes available data on existing icebreaking ships to compile a review of the design features that influence ship performance. The data were extracted from a recently completed review of the state of the art of Arctic ship technology and include icebreaking ships from Argentina, Canada, Denmark, Finland, Japan, Sweden, the United Kingdom, the Soviet Union, the United States, and West Germany. It is the aim of this paper to offer guidance in the initial stages of icebreaker design and thereby give confidence to the designer in the selection of dimensions, hull shape and propulsion.

This chapter explores the use of aircraft to spray organochlorine pesticides (OCPs). It begins by tracing the origins of the practice in KwaZulu, South Africa, where ndege were adopted for pesticide spraying because of their ease of use, capacity for large-scale coverage, very few personnel required, and capability to reach mpukane habitats otherwise inaccessible by ground spraying. The second section examines the technical aspects of aerial spraying as an example of the extension of methods designed in the United States for agricultural or military purposes to deal with zvipukanana and with conditions for which they were not originally designed. In the final sections, the deployment and performance of first fixed-wing aircraft and then helicopters are closely examined.
