  • I don’t think it is necessarily “selecting”. I’m not exactly sure what it is. But what I found in the article that at least starts to get at your questions is:

    Approximately 45% of Black women experienced stalking, physical and sexual violence in their lifetimes, and an estimated 51% of Black female adult homicides were related to intimate partner violence, according to The National Coalition Against Domestic Violence. Intimate partner violence was also a key contributor of homicide in Black women, Waller’s paper notes.

    …Karma Cottman, chief executive officer for Ujima Inc., a resource center focused on ending domestic, sexual and violence within Black communities. Cottman said the statistics are a direct result of economic instability and a large access to firearms.

    It goes on to talk about the relationship stresses of economic instability.

    Also

    Many Black women also have a fear of calling law enforcement, Cottman added, which puts them “at greater risk for experiencing violence” since they do not ask for police intervention until a situation turns deadly.

    I’m just passing along relevant bits of the article. I think the above quote would need more study as it strikes me as complex factors interacting. How many black women are killed by the police? I have no idea. How many die as a secondary result of police encounters? How does that compare to not getting police intervention sooner?

    A 2020 study published in the National Library of Medicine found that Black and Latina women who experienced intimate partner or sexual violence were two to three times more likely to experience abuse or a neglectful response from law enforcement when reporting the incident.

    Finally, what to do?

    Waller is calling for more gun legislation and said more work needs to be done to dismantle inequities that directly impact Black women.

    Based on smell.

    Sulfur mustards are viscous liquids at room temperature and have an odor resembling mustard plants, garlic, or horseradish, hence the name

    One of my relatives got hit with it in WWI. As a result, in later years, he went blind and had lung issues that ended up killing him way too young. He (and apparently others in his company) had to fight to get disability.

    I was told the enemy would first fire a gas that would induce vomiting so soldiers would have to take off their gas masks to puke just in time for them to fire the really bad shit. I haven’t verified that detail though so maybe it got mixed up hearing it third hand. He died years before I was born.














  • I think it can be compensated for to some small degree. But… A deeper explanation is needed.

    A plane has a center of mass (or gravity) which is the gravity balance point of the plane. It also has a center of lift which is like the center of gravity but for the lift force of the wing. See pic:

    If the center of lift and center of gravity aren’t in the same horizontal location along the length of the plane, the plane has a net force that rotates the nose up or down.

    It’s like if you had a yard stick and balanced it on your finger. And then added a weight somewhere between your finger and one end. The yard stick will start to rotate (tilt).

    The horizontal stabilizer applies a force as well, and it is trimmed to balance the other forces and set the angle of attack (pitch) of the plane. The elevator allows momentary adjustment of pitch.

    I may not describe this perfectly but… When a plane has too much weight towards the rear, it will be unstable (and dangerous) to fly. When a plane has too much weight towards the nose it will be somewhat sluggish but stable.

    Balancing nose heavy is preferable to tail heavy in general due to the stability issue. A little bit of tail heavy is a bit dangerous and a bit of nose heavy is no big deal. I think another factor is that the tendency of a plane to pitch up could result in aerodynamic stall (loss or lift). Of course, if a plane is too nose-heavy, you can’t climb.

    Front to back balance is really important to how the plane handles. Side to side balance matters but in terms of passengers / cargo, they’re more narrowly distributed about the center of the plane compared to their distribution front to back.
