Abstract
Zero trust (ZT) is the term for an evolving set of cybersecurity paradigms that move defenses from static, network-based perimeters to focus on users, assets, and resources. A zero trust architecture (ZTA) uses zero trust principles to plan industrial and enterprise infrastructure and workflows. Zero trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personally owned).

What Is The Outstanding Characteristics for ZTA?
ZTA (Zirconia Toughened Alumina) is a composite material made from alumina and zirconia. It combines the outstanding characteristics of both materials.
Compared to conventional alumina, ZTA possesses superior hardness, higher flexural strength, and similar density. Compared to conventional zirconia, it possesses a lower coefficient of linear thermal expansion and higher thermal conductivity.
By leveraging these features, ZTA has been widely adopted in milling parts and wear-resistant parts that require cooling.
ZTA (Zirconia Toughened Alumina)
Features:
- High Stiffness and Outstanding Wear Resistance
- Stiffer than alumina with outstanding wear resistance equivalent to zirconia.
- High Thermal Conductivity and Low Thermal Expansion
- Suppresses thermal deformation through thermal conductivity and low thermal expansion equivalent to alumina. Suitable for components requiring a cooling Mechanism.
- High Strength and Specific Rigidity
- Approximately twice as strong as alumina and contributes to low-weight design through high specific rigidity.

Zimbabwe needs more airlines after Comair demise
Zimbabwe needs more airlines after Comair demise
from DANIEL JONES in Victoria FallsVictoria Falls BureauVICTORIA FALLS, (CAJ News) – TOURISM stakeholders have implored authorities to lure more airlines into Zimbabwe, following the decision by Comair to suspend operations to the country.
The airline based in neighbouring South Africa, from where it operated British Airways and Kulula, is doomed amid viability challenges.
Comair was among the…

f1 drivers + sororities .ೃ࿐
a lovely anon asked me what sororities f1 drivers would be sorted into so here we go. i would like to say as a disclaimer is that greek life varies from campus to campus, so do take my opinions with a grain of salt. also, i was vp of recruitment last year so i know a thing or two about matching girls with chapters hehe.
i am gonna do class of 2023, with a bonus of our two fav reserve drivers so here we go! also, i'm including sororities that aren't on my campus and doing very limited research on them.
max v. - delta zeta
i dont have much knowledge on dz (seeing as they were kicked off my campus before i rushed), BUT they were the it girls on my campus. they we're top house, everyone either loved or hated them or wanted to be them.
checo p. - gamma phi beta
gphi on my campus is so hit or miss (as are most organizations, but the chapter on my campus is more out right about it). they're either really nice or they really mean. i think checo has that charm about him LOL
charles l. - alpha chi omega
i don't have achi o on my campus, but of every video i've seen about them, they are more often than not the pretty, philanthropic, top house kind of gals. charles would fit right in. (also the cherry on top is that red is one of their colors).
carlos s. - kappa kappa gamma
i know nothing about kkg, but their mission statement says "...respect for intellectual development, and an understanding of and an allegiance to positive ethical principles" which i feel like is very carlos. carlos is always trying to learn more and get a better understanding.
lewis h. - alpha phi alpha / not rush
lewis would NOT join a phc organization. he would join one of the divine nine for sure, just in solidarity with culture and history. but i will say that the rush/pledging process of the divine can be fucking brutal so there's a chance he'd drop. or better yet, he wouldn't rush at all because he's better than that.
george r. - zeta tau alpha
george would 100% be a zeta. zeta is also a very top house sorority, but when you're zeta you are a die hard zeta. i feel like every sister of zta i've met lives and breathes zta. very george.
esteban o. - delta delta delta
they describe their org to be "an assembly of women with shared values where you can be yourself and belong to something bigger. we are brave, bold and kind." thats so esteban, and considering the work he's put into alpine + the time he's spent in the team. very este bestie of him.
pierre g. - pi beta phi
i was gonna make him a zta, but when i was reading other sorority values i came across this chapter. under reputation it said "many consider them obsessed with their looks" and that just feels like pierre.
lando n. - sigma kappa
sk on my campus is on the come up. they recruit a bunch of cute, sweet little girls who are very active on campus. they're everywhere. like lando. he's every where.
oscar p. - gamma phi beta
i know what i said under checo but pretend you didnt read it for this. oscar is also gphi to me because theyre new member class is so bold and just wants to be involved in everything. giving oscar energy i think.
valterri b. - alpha gamma delta
agds on my campus arent top house by any means, and they have girls who you would've thought would end up in top house but they chose agd. thats valterri to me.
zhou g. - alpha xi delta
these girls on my campus are super underrated. known to have the most genuine sisterhood on campus. they aren't super active on campus, and aren't super well known. but the people the know them, love them.
lance s. - kappa kappa gamma
aligning with carlos. i think lance does try his best at what he does, and improve. he definitely aims to be bigger than daddy's boy. you know?
fernando a. - pi beta phi
please he is just pretty. thats all fernando would bring to the table. he's a pretty boy and should be in a pretty sorority.
kevin m. - alpha gamma delta
i love agds so much. they're a bunch of goofy girls who are loved by a lot of people. theyre on the smaller side on my campus, but are just full of girls you would generally like.
nico h. - alpha gamma delta
this also makes sense to me because he just- he loves f1 and he'll never leave. i've met my fair share of 25+ greek women in their chapter and they just...... never leave. but he's dedicated. and that counts for something...... right?
yuki t. - alpha phi gamma
an asian sorority. i love these girls. theyre so goofy, but really sweet and also die hard for their chapter. yuki would thrive.
nyck d.v. - alpha delta pi
i love my adpis. so much. they're the sweetest girls ever. on my campus theyre super strong in academics and support so many diff organizations on campus. nyck is one hundred percent an adpi.
alex a. - alpha phi
part of their mission statement is "high expectations for character and a drive for innovation" which i feel is alex coded. i can't say what exactly, but alex just screams that.
logan s. - zeta tau alpha
he just has the look that would land him into zeta. what he brings to the table, we'll just have to wait and see.
bonus !
daniel r. - alpha delta pi
he gives me vibes of one of my friends in adpi. just always so happy and dedicated to their chapter. also daniel gives off the vibe of adpis on my campus. and he'd 100% be a sweetheart of a fraternity.
mick s. - delta gamma
their values read "foster high ideals of friendship among women, to promote their educational and cultural interests, to create in them a true sense of social responsibility, and to develop in them the best qualities of character." i just think thats mick. always fostering growth and developing his charachter.
another addition to d's shitpost studies. submit an ask if there are other topics you would like me to do!
