A production process is provided for a drill including the following steps. From a rod-shaped blank comprising an end section, a central section, and a hollow space extending at least through the end section and the central section along an axis of the blank, the end section is formed in a direction extending radially relative to the axis, the diameter of the hollow space in the end section being reduced. Either a cutting element is attached to the end section or grooves are introduced into the end section for forming a shank.

(United States Supreme Court) - Addressed what law applies on the Outer Continental Shelf, holding that California wage-and-hour law was inapplicable to a worker on an offshore drilling platform. Under the Outer Continental Shelf Lands Act, if federal law addresses the relevant issue, state law is not adopted as surrogate federal law. Justice Thomas delivered the opinion for a unanimous Court.

Hi all,

I am creating shapes on plane layers for a coupon and want to void them using axlShapeAutoVoid()

The shapes are attached to a symbol.

I've tried using axlShapeAutoVoid, but this only voids the pins, not the route keepouts created by nc_backdrill.

I also tried selecting the shape, individually, then running axlShapeAutoVoid. That was unsuccessful, also.

planeShapes is a list of shapes I created. The code for voiding:

;run backdrill to get route keepouts
axlShell("setwindow pcb;backdrill setup ;setwindow form.nc_backdrill;FORM nc_backdrill apply ;FORM nc_backdrill close")

foreach(sHape planeShapes
axlShapeAutoVoid(car(sHape))
)

Balamuthia mandrillaris is an under-reported, pathogenic free-living amoeba that causes Balamuthia amoebic encephalitis (BAE) and cutaneous skin infections. Although cutaneous infections are not typically lethal, BAE with or without cutaneous involvement is usually fatal. This is due to the lack of drugs that are both efficacious and can cross the blood-brain barrier. We aimed to discover new leads for drug discovery by screening the open-source Medicines for Malaria Venture (MMV) Malaria Box and MMV Pathogen Box, with 800 compounds total. From an initial single point screen at 1 and 10 μM, we identified 54 hits that significantly inhibited the growth of B. mandrillaris in vitro. Hits were reconfirmed in quantitative dose-response assays and 23 compounds (42.6%) were confirmed with activity greater than miltefosine, the current standard of care.
