One way to reduce the negative impact of farrowing crates on sow welfare is to limit confinement of sows from the onset of farrowing until the end of the critical period of piglets’ life a few days after farrowing. In order to provide an indication of the time when sows should be confined in crates, ear tag-based acceleration data was modeled to provide the following two types of alarms: A “first-stage” alarm that indicates the beginning of nest-building behaviour, and a “second-stage” alarm that indicates the ending of the nest-building behaviour. In total, 53 sows were included in the experiment. Each sow had an ear tag with an accelerometer sensor mounted on the ear. Acceleration data were modeled with the Kalman filtering and fixed interval smoothing (KALMSMO) algorithm. It was possible to predict farrowing on the basis of increased activity in the validation dataset with a median of 8 h 51 min before the onset of farrowing. Alarms that indicated the need for confinement of the sow in a crate were generated with a median of 2 h 3 min before the onset of farrowing. These results suggest that the developed model should be sufficient to provide early warning of approaching farrowing and secondary alarm indicating the need to confine a sow in a crate.

Background: Closed-source software for processing and analyzing accelerometer data provides little to no information about the algorithms used to transform acceleration data into physical activity indicators. Recently, an algorithm was developed in MATLAB that replicates the frequently used proprietary ActiLife activity counts. The aim of this software profile was (a) to translate the MATLAB algorithm into R and Python and (b) to test the accuracy of the algorithm on free-living data. Methods: As part of the INTErventions, Research, and Action in Cities Team, data were collected from 86 participants in Victoria (Canada). The participants were asked to wear an integrated global positioning system and accelerometer sensor (SenseDoc) for 10 days on the right hip. Raw accelerometer data were processed in ActiLife, MATLAB, R, and Python and compared using Pearson correlation, interclass correlation, and visual inspection. Results: Data were collected for a combined 749 valid days (>10 hr wear time). MATLAB, Python, and R counts per minute on the vertical axis had Pearson correlations with the ActiLife counts per minute of .998, .998, and .999, respectively. All three algorithms overestimated ActiLife counts per minute, some by up to 2.8%. Conclusions: A MATLAB algorithm for deriving ActiLife counts was implemented in R and Python. The different implementations provide similar results to ActiLife counts produced in the closed source software and can, for all practical purposes, be used interchangeably. This opens up possibilities to comparing studies using similar accelerometers from different suppliers, and to using free, open-source software.

Garbage was defined as the residue of people's daily activities. In the social environment, to facilitate decomposition, garbage was generally grouped into two simple parts; namely organic garbage and inorganic garbage. garbage management was needed to reduce the possibility of positive and negative impacts to the environment. Economic value was grouped into positive impact, while the source of odors and disease clusters were grouped as negative impact. In this study, the focus of the problem is on the negative group. Because if garbage is allowed to pile up in one place in community settlements, it will become a source of unpleasant odors so that it can then become an area for germs to develop.

The process of realizing this illustration book work used several stages, the first stage was the process of collecting data about garbage and its processing, then data on the type of book that match the target audience.

Descriptions of Sciurus ingrami Thomas, 1901 nests are not available in the literature. In this study, a survey was made of the distribution of S. ingrami nests in a woodlot located near to the headquarters of the Serra do Caraça Reserve, in state of Minas Gerais, where there is a high concentration of Syagrus romanzoffiana (Chamisso) Glassman palm tree, among other exotic tree species. The nest-building behaviour and the nest characteristics, such as height from the ground, total circumference, diameter of the entrance, and the position of the nest in the tree - in the crown, along the trunk or in a side branch, were described.

The soybean cyst nematode (SCN)–soybean pathosystem is often reproduced under greenhouse conditions for basic research purposes, increasing inoculum, and soybean germplasm screening. Application of pesticides for SCN bioassays is often necessary for keeping insect and mite pest populations under control. The research presented here looks at the application of several foliar pesticides (active ingredients; abamectin, bifenthrin, clofentezine, imidacloprid, kinoprene, and pyridaben), a soil-applied imidacloprid, and combinations of pesticides on bioassays to determine if pesticide applications have a negative impact on SCN female and cyst numbers as well as egg and second-stage juvenile (J2) production, which could lead to dubious results. Results from this experiment demonstrate these chemicals can be used to control pest populations on soybean without significantly altering SCN female, cyst, egg, and J2 counts.
