Delta Variant Quotes

The F-110 designation was applied to the initial F-4 Phantom II variant operated by the USAF covering 29 F4H-1 (F-4B) carrier borne fighters loaned to the USAF by the USN for evaluation. In the early 1960’s the USAF was looking for a new tactical fighter, which came down to a fly-off competition between the Convair F-106 Delta Dart (then in USAF ADC service as an interceptor) and the USN McDonnell F4H-1 Phantom II. While the USAF traditionally opposed adopting naval fighter aircraft the Phantom II had obvious advantages over the F-106, being designed with true multi-role capability, whereas, the F-106 had been optimised for the interception role.

FDM (Fused Deposition Modeling) printers There is no hard and fast classification of the FDM 3D printers Cartesian 3D Printers: These are the most common type, operating on a straightforward Cartesian coordinate system with linear rails guiding movement along the X, Y, and Z axes. They are recognized for their simplicity and reliability. Delta 3D Printers: Delta printers employ a triangular configuration of three arms attached to moving carriages at the printer's apex. The print head hangs from these carriages, executing precise movements to craft the intended object. Delta printers excel in speed and consistency, particularly in producing tall items. CoreXY 3D Printers: CoreXY printers utilize a distinctive belt-driven mechanism to maneuver the print head across the X and Y axes. This design separates the print head's motion from that of the build platform, resulting in swifter and more accurate prints. Enthusiasts favor CoreXY printers for their speed and precision. Polar 3D Printers: Polar printers feature a circular build platform and a print head that moves both radially and vertically. This configuration facilitates continuous rotation of the print bed, enabling the creation of objects with intricate geometric shapes. Polar printers are commonly employed for crafting artistic and sculptural pieces. SCARA 3D Printers: SCARA (Selective Compliance Articulated Robot Arm) printers utilize a robotic arm mechanism to navigate the print head in a two-dimensional plane. This design offers rapid and precise movement, making SCARA printers ideal for producing small, intricate objects with exceptional accuracy. Each variant of FDM 3D printer has its own strengths and is tailored to diverse applications, spanning from hobbyist endeavors to industrial-scale manufacturing.

Early in the pandemic, there was a broad belief in the scientific community that, although there would be some mutations of COVID, they wouldn’t cause a big problem. By early 2021, scientists knew that variants were emerging, but they appeared to be evolving in similar ways, leading some scientists to hope that the world had already seen the worst mutations that the virus was capable of. But the Delta variant proved otherwise—its genome had evolved to make it far more transmissible. The arrival of Delta was a bad surprise, but it convinced everyone that even more variants could show up. As I finish this book, the world is facing a sweeping wave of Omicron, the fastest-spreading variant to date—and in fact the fastest-spreading virus we’ve ever seen.

We had the Delta variant, now there is the B.1.1.529. Should we be concerned? YES!

Norepinephrine: The Wake-Up Neurotransmitter One of norepinephrine’s effects on the brain is to sharpen attention. As we saw earlier, norepinephrine (aka noradrenaline) can function as both a neurotransmitter and a hormone. When we perceive stress and activate the fight-or-flight response, the brain produces bursts of norepinephrine, triggering anxiety. But sustained and moderate secretion can also produce a beneficial result in the form of heightened attention, even euphoria, and meditation has been shown to produce a rise in norepinephrine in the brain. A modest dose of norepinephrine is also associated with reduced beta brain waves. 5.11. Norepinephrine: your wake-up molecule. Notice the paradox here. Norepinephrine is associated with both anxiety and attentiveness. How do you get enough to be alert, but not so much you’re stressed? Surrender is the key. Steven Kotler, co-author of Stealing Fire, says that stress neurochemicals like norepinephrine actually prime the brain for flow states. At first, the meditator is frustrated by Monkey Mind. But if she surrenders, despite the perpetual self-chatter of the DMN, she enters the next phase of flow, which is focus. She has hacked her biology, using the negative experience of mind wandering as a springboard to flow. Norepinephrine’s molecular structure is similar to its cousin, epinephrine. While epinephrine works on a number of sites in the body, norepinephrine works exclusively on the arteries. When both dopamine and norepinephrine are present in the brain at the same time, they amplify focus. Attention becomes sharp, while perception is enhanced. Staying alert is a key function of the brain’s attention circuit, which keeps you focused on the object of your meditation and counteracts the wandering mind. It also stops you from becoming drowsy, an occupational hazard for meditators. That’s because pleasure neurotransmitters such as serotonin and melatonin (for which serotonin is the precursor) can put you to sleep if not balanced by alertness-producing norepinephrine. Again, the ratios are the key. Oxytocin: The Hug Drug 5.12. Oxytocin: your cuddle molecule. Oxytocin is produced by the hypothalamus, part of the brain’s limbic system. When activated, neurons in the hypothalamus stimulate the pituitary gland to release oxytocin into the bloodstream. So even though oxytocin is produced in the brain, it has effects on the body as well, giving it the status of a hormone. It is one of a group of small protein molecules called neuropeptides. A closely related neuropeptide is vasopressin. All mammals produce some variant of these neuropeptides. Oxytocin promotes bonding between humans. It is responsible for maternal feelings and physically prepares the female body for childbirth and nursing. It is generated through physical touch but also by emotional intimacy. Oxytocin also facilitates generosity and trust within a group. Oxytocin is the hormone associated with the long slow waves of delta. A researcher hooking subjects up to an EEG found that touch stimulated greater amounts of delta, with certain regions of the skin being more sensitive. The biggest effect was produced by tapping the cheek, as we do in EFT. It produced an 800% spike in delta.

To Covid: Seriously, fuck you. To the Delta variant: With a cactus.

Report published : #Globalization of #disease has led the world to be only as resilient as the least resilient country and person , especially for highly contagious COVID-19 which has spread with scale and severity not seen since #Spanishflu . The variants of the virus (such as B.1.617.2 Delta , #DeltaPlus, Epsilon, #Gamma ) continue to threaten even those vaccinated. Secondary diseases such as black fungus are targeting #COVID patients and killing almost one in two persons in such cases. Human life is more precious and important than all economic principles or systems in totality because all these concepts are legitimate only because of their utility value which is to fundamentally make human life better. At least until this ongoing crisis ends, all economic policies (related to money, banking, fixing prices of commodities, etc.) need to be revised to make sure no human being suffers from hunger or the absence of required medical care. For this purpose KAILASA has presented a detailed report on effective solution for
