Lithium chemicals have been proven to be very effective in eradicating Varroa destructor, the detrimental parasite of the honey bee; however, little is known about the side effects on brood and long term consequences on the colony.Earlier, it was proposed Placemat that the action mechanisms of lithium chloride do not include the contact mode.Here,
The era of the coronavirus disease pandemic is increasingly driving the process of transforming teacher Placemat education and training from face-to-face to online-based.Besides having flexibility and accessibility, in practice, the transformation process has several weaknesses and challenges.One of them is a culture of self-regulated learning from
Feedrate scheduling is one of the most critical technologies in CNC machining, requiring a reasonable balance between efficiency and quality.This paper proposes a jerk-continuous feedrate smoothing (JCFS) method to generate a low-vibration and smooth feedrate profile for non-uniform rational B-spline (NURBS) interpolation.Firstly, the segmentation
Bulk sampling and extensive, systematic surface collecting of the Coon Creek Member of the Ripley Formation (early Maastrichtian) at the Blue Springs locality and primarily bulk sampling of the Owl Creek Formation (late Maastrichtian) at the Owl Creek type locality, both in northeast Mississippi, USA, have produced the largest and most highly diver
This study aims at introducing two conservative thermodynamic variables (moist-air entropy potential temperature and total water content) into a one-dimensional variational data assimilation system (1D-Var) to demonstrate their benefits for use in future operational assimilation schemes.This system is assessed using microwave brightness temperature
