Comparison of frameworks for defining land occupation considering on-farm and off-farm feed production on Italian dairy farms.

Land occupation (LO) is one of the most frequently discussed aspects of livestock competition with agricultural activities. commonly In this study the area needed to produce purchased feeds for animal nutrition, was used to estimate the off-farm land occupation of dairy farms, allowing for a precise calculation of the total land occupation requirement for milk production (on-farm plus off-farm LO, expressed in m per unit of standardized milk). We use 4 approaches (LO1, LO2, LO3A and LO3B) to calculate the off-farm land used for milk production on dairy farms and apply them to 14 dairy farms in northern Italy as a case study.

A 3D-Printed Bi-Material Bragg-Based Reflectarray Antenna.

This paper presents a 3D-printed fully dielectric bi-material reflectarray with bandgap characteristics for multi-band applications. To achieve bandgap characteristics, a "1D Bragg reflector" unit cell is used. The latter is a layered structure characterized by a spatial distribution of refractive index that varies periodically along one dimension.

MicroRNA Profiling as a Predictive Indicator for Time to First Treatment in Chronic Lymphocytic Leukemia: Insights from the O-CLL1 Prospective Study.

A "watch and wait" strategy, delaying treatment until active disease manifests, is adopted for most CLL cases; however, prognostic models incorporating biomarkers have shown to be useful to predict treatment requirement. In our prospective O-CLL1 study including 224 patients, we investigated the predictive role of 513 microRNAs (miRNAs) on time to first treatment (TTFT). In the context of this study, six well-established variables (i.
