Post-dipping in Milk Production, Composition, and Quality

This study aimed to evaluate the influence of post-dipping on milk production, composition, and quality of cows with subclinical mastitis. Samples of mast milk from two different dairy farms were analyzed in two moments: before the post-dipping implantation and after 30 days, the samples were conditioned to the refrigeration temperature in an isothermal box and sent to the laboratory for the following analyzes: California Mastitis Test (CMT), Somatic Cell Count (SCC), Fat, Protein, Lactose, Total Solids (TS), Non-Fat Solids (NFS) and microbiological tests, as well as individual milk weighing. The experimental design was completely randomized and arranged in a split-plot scheme, submitted to analysis of variance (ANOVA) by the F test. The post-dipping practice during 30 days resulted in the means and standard deviation of the analyzes of the studied variables, where the values of SCC, CMT, and microbiological score profile were statistically significant. The highest etiological agent found was Staphylococcus spp. The fat and lactose profile increased in both farms, but there was no significant difference. Protein increased in both farms, but in farm I, there was no significant difference and in farm 2, there was a significant difference. Total Solids, Non-greasy solids, and weighing had a percentage increase, but the means of weight did not differ statistically. The post-dipping technique was an effective measure in the control of subclinical mastitis and brings health benefits to the mammary gland.

Velocidade terminal: Tempo chronoscopico dos corpor obritais na composição sonora e musical.

This essay presents the methodologies, meanings and challenges in the development of the “Dromology of Orbital Bodies”, Hugo Paquete project, started between 2019-2020 and still ongoing. The project aims to track military and commercial satellites, by converting their movement information in real time by a process of data sonification received from the hacked satellites. Therefore, this essay presents the technical challenges in the project building, as well some of the obtained sonic results. Also is presented the dimension of conceptual meanings associated with the project from a philosophical and critical point of view, in a combination of conceptual approach and technical exploration where concepts such as chronoscopic time, cyberpunk, gray ecology and acoustemology are related as conceptual frames, of a time where the sound happens mediated by technology. The presented concepts are influences in the production, composition and musical performance processes that I develop with special interest in systems theory and where unpredictability operates alongside real-time relationships. In this experimentation I use sound granularization and compositional aesthetic techniques historically centered in a noise and micro post-digital rhythm aesthetics.
