Composition of White Rhinoceros Colostrum and Changes During Early Lactation to Mature Milk
The colostrum phase of white rhinoceros milk ends after 2 days of lactation. The mature milk phase commences after 5 days. The fat content peaks at days 3–4. The Δ9‐desaturase 16 and ‐18 indexes peak at days 2–3. ABSTRACT The proximate composition of milk from seven free‐ranging white rhinoceroses during the first 20 days of lactation is reported with ...

Machine learning approach of multi‐RAT selection for travelling users in 5G NSA networks
The authors present RAT selection algorithm for efficient resource allocation for public bus travelling user(s), utilising live data from multiple 5G NSA base stations. Models of the supervised machine learning algorithms: SVM, DNN and XGBoost were deployed for implementation to predict or select the appropriate RAT between 4G and 5G RATs.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,
