If you're looking for a complete SQL tutorial for beginners with examples, this tutorial is a great way to learn SQL basics. Just follow through and you'll be able to write SQL queries in no time.

SQL, short for Structured Query Language, is a language used by software developers, data scientists and anyone who works with data. With SQL, you can store data in relational databases and write queries to extract valuable information.

There are various database management systems (DBMS) that support SQL but each product has its own implementation of SQL. In this course, we'll be using MySQL to learn SQL. MySQL is the most popular free and open-source database management system in the world. If you use a different DBMS (eg SQL Server), you can still benefit from this course as 90% of the skills you'll learn in this course can be transferred to other database management systems.

How to Clone Cannabis Plants Easy 121gamers 18 צפיות • לִפנֵי 2 חודשים

I am licensed to grow cannabis here in Canada and this is for documentary and educational purposes only.

Hello, today I am going to show you how to take clones or cuttings from cannabis plants.

I am going to take some cuttings of my Blackberry Moonrocks from Anesia Seeds that claim to have THC levels of 33%, while smelling like blueberries and lavender.

The first thing I do is fill a narrow glass with water and throw Rapid Rooter peat plugs into some water to soak.

I make sure the Rapid Rooter is wet, without much water dripping from it.

I will then select a branch which is healthy and around six inches long.

After cutting, immediately place it in some water to avoid air bubbles entering the stem.

I will then trim off the bottom nodes and cut below one of the nodes at a 45 degree angle.

I then carefully place the cutting into a Rapid Rooter, pick off some peat, and use it to fill the hole.

Sometimes I will keep all the leaves, but where I need the space, I am going to trim them today.

I then place them into a GroDan smart tray, which keeps the Rapid Rooters off the bottom of the clone dome.

I keep the environment warm with above 90% humidity, using a clone dome, and will dunk the Rapid Rooters in water if they get too dry over the next three weeks.

This Blackberry Moonrocks will be going into flower within the next few weeks.

This is Zeebone Grows and if you have any questions, please leave them in the comment section, and thank you for watching.

Springfield Prodigy 1911 DS Review - Is This Gun A Game Changer? cashinvids 22 צפיות • לִפנֵי 3 שנים

Springfield Prodigy 1911DS Review
https://bit.ly/2CHLudt

Springfield just made a Double Stacked 1911 chambered in 9mm.

I was born and raised in the south, and in the south, we call all soft drinks "COKE", all tissues Kleenex, and all bandages Band-AIDs.

Many people in the gun world tend to call any double stack 9mm 1911 a 2011.

But that's not technically correct.

That's because all 2011s are essentially double-stacked 1911s, but not all double-stack 1911s are 2011s.

There are two versions of the Prodigy:

A 4.25" Forged Stainless Steel, Match Grade, Bull Barrel

and

A 5" Forged Stainless Steel, Match Grade, Bull Barrel.

Everything else is exactly the same.

Same grip and a grip length, same Forged Carbon Steel frame, the same Forged Carbon Steel Slide that is optics ready, same 2 Piece Full-Length Guide Rod, and they both come with one 17 Round and 20 Round Magazine.

Also, I am just launching 2 NEW Products.

First, my NEW Colion Noir Edition In-Ear Hearing Protection!

Once you wear these, you’ll immediately feel the difference with SUPERIOR comfort and enhanced situational awareness.

The comfort feels like custom-fit protection and is easily worn for hours without constantly falling out.

They feature 6x SOUND AMPLIFICATION, Fast Attack Time, & NRR 29 Rated

New positive ivermectin evidence 121gamers 18 צפיות • לִפנֵי 2 חודשים

A Pilot, Randomised, Placebo-Controlled, Double-Blind Trial of a Single Oral Dose of Ivermectin for Post-Exposure Prophylaxis of SARS-CoV-2

https://www.mdpi.com/1999-4923/17/9/1205

People who took one small oral dose of ivermectin after exposure,

took longer to test positive and had more time alive and free of symptoms.

Multiple reports from in vitro infectious models document Ivermectin’s antiviral properties

https://pmc.ncbi.nlm.nih.gov/a....rticles/PMC7564151/p

Ivermectin has broad-spectrum antiviral activity.

Randomised, double-blind, placebo-controlled

Single oral dose of Ivermectin as prophylaxis for SARS-CoV-2

Trial to evaluate the effectiveness of a single oral low dose of Ivermectin

Ability to prevent SARS-CoV-2 infection?

Ability to reduce symptoms if infection did occur?

Methods

Asymptomatic community-dwelling adults

Enrolled within 72 h of close contact with a case of SARS-CoV-2.

Single oral 200 µg/kg dose of Ivermectin or placebo.

65Kg woman given 13mg

80Kg man given 16mg

The primary outcome

Conversion to a positive PCR or RAT test within 14 days of close contact.

Secondary outcomes

(for those who tested positive)

Days alive free of symptoms in the 14 and 28 days following ivermectin

Days from close contact until a positive PCR or RAT

Results

N = 536 (86 met inclusion criteria and were randomised)

68 adhered and were included in the analysis.

Ivermectin arm

11/36 tested positive

Placebo arm

11/32 tested positive

So, ivermectin did not prevent people testing positive

Days from close contact until a positive PCR or RAT

Increased by 2.3 days in ivermectin group.

P = 0.033

So, ivermectin lengthened the incubation period

Viral load needed to precipitate clinical disease took longer to develop – indicating an antiviral effect.

Infection may have been prevented from primary contact, - indicating an antiviral effect.

Days alive free of symptoms

Increased by 2.5 days in ivermectin group.

P = 0.036

So ivermectin delayed onset of symptoms in people who tested positive

(Longer asymptomatic period)

Controlling included

Age, prior SARS-CoV-2 infection, body mass index, hypertension, lung disease

Conclusions

We did not demonstrate that a single oral low dose of Ivermectin administered to asymptomatic adults within 72 h of close contact with a case of
SARS-CoV-2 prevents conversion to a positive PCR or RAT.

(may have done with a larger sample size)

Amongst those who did convert to a positive PCR or RAT

Ivermectin significantly lengthened the time from close contact to conversion

Ivermectin increased the number of days alive free of symptoms

More details

Initiation of this trial in late 2021

Discovery in 1975

Massively used around the world

Nobel Prize in 2015

Very low incidence of serious adverse side effects

No instance of resistance reported in over 25 years.

Ivermectin can bind to and inhibit the nuclear transport roles of the host importin α (IMPα) protein,

which is known to mediate the nuclear import of various viral proteins and key host factors.

Other quite distinct antiviral actions of Ivermectin have been proposed

High (therapeutic) concentrations collect in the lungs, stable for more than 30 days in cattle

Trial was based on the strong clinical retrospective association of statistically significantly lower mortality in patients who received oral Ivermectin (200 μg/kg) compared with usual care

https://www.sciencedirect.com/....science/article/pii/

Ivermectin patients 15% mortality

Controls, 25.2% mortality

In subjects with severe pulmonary disease

Ivermectin patients, mortality 38.8%
Controls, 80.7% mortality
