The legal complications and the damage to be paid is holding back the massive ship. Egyptian authorities have held back the Ever Given massive ship that got stuck on the Suez Canal on 23rd March. The authorities have asked its operators to pay $1 billion in damages to get a free pass for their ship.
- Shift Handover Software Enables Communication 24/7 All shift operations are documented in real time and clearly present the information when the shift changes. Eliminate shift handover errors through improved communication with our shift handover solution Customized forms to fit plant operations.
- Over time, the change in your bottom teeth can affect your bite, causing a shift in your upper teeth. The changes may be so slight that nothing needs to be done. But some people may need tooth.
Some functions (like Sine and Cosine) repeat forever
and are called Periodic Functions.
The Period goes from one peak to the next (or from any point to the next matching point):
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.
The Phase Shift is how far the function is shifted horizontally from the usual position.
The Vertical Shift is how far the function is shifted vertically from the usual position.
All Together Now!
We can have all of them in one equation:
y = A sin(B(x + C)) + D
- amplitude is A
- period is 2π/B
- phase shift is C (positive is to the left)
- vertical shift is D
And here is how it looks on a graph:
Note that we are using radians here, not degrees, and there are 2π radians in a full rotation.
Example: sin(x)
This is the basic unchanged sine formula. A = 1, B = 1, C = 0 and D = 0
So amplitude is 1, period is 2π, there is no phase shift or vertical shift:
Example: 2 sin(4(x − 0.5)) + 3
- amplitude A = 2
- period 2π/B = 2π/4 = π/2
- phase shift = −0.5 (or 0.5 to the right)
- vertical shift D = 3
In words:
- the 2 tells us it will be 2 times taller than usual, so Amplitude = 2
- the usual period is 2π, but in our case that is 'sped up' (made shorter) by the 4 in 4x, so Period = π/2
- and the −0.5 means it will be shifted to the right by 0.5
- lastly the +3 tells us the center line is y = +3, so Vertical Shift = 3
Instead of x we can have t (for time) or maybe other variables:
Example: 3 sin(100t + 1)
First we need brackets around the (t+1), so we can start by dividing the 1 by 100:
3 sin(100t + 1) = 3 sin(100(t + 0.01))
Shift Over Meaning
Now we can see:
- amplitude is A = 3
- period is 2π/100 = 0.02 π
- phase shift is C =0.01 (to the left)
- vertical shift is D = 0
And we get:
Frequency
Frequency is how often something happens per unit of time (per '1').
Example: Here the sine function repeats 4 times between 0 and 1:
So the Frequency is 4
And the Period is 14
In fact the Period and Frequency are related:
Frequency = 1Period
Period = 1Frequency
Example from before: 3 sin(100(t + 0.01))
The period is 0.02π
So the Frequency is 10.02π = 50π
Some more examples:
When frequency is per second it is called 'Hertz'.
Example: 50 Hertz means 50 times per second
The faster it bounces the more it 'Hertz'!

Shift Overflow
SHIFT by Dana Perri has gone virtual! I am offering SHIFT classes online using ZOOM. You can take classes from the comfort of your home while we all stay at home.
What is ZOOM?
ZOOM is a web-based video conferencing tool. Students receive an invitation and log into a class through the ZOOM app. You can see and hear me on your screen as I lead each class. There are desktop and mobile apps available. You download them onto your device so we can communicate. You can use the ZOOM desktop app, which is available for Windows and macOS, while the mobile app is available for Android and iOS .
Shift Overflow
ZOOM allows you to take a virtual SHIFT class wherever you’d like to exercise. In your bedroom, home gym, living room, garage, or wherever you’re comfortable! It’s up to you.
When are classes?
I’ll post the SHIFT schedule of classes on the MindBody website, where class schedules have always been kept. The classes are for all levels. I’ll provide the modifications as we go. ZOOM classes will open 10 minutes prior to start time. Be sure to login early if you are new to this platform.
Please check the Class Schedule
Memberships/Class Packages
Memberships will continue as always. If you have autopay monthly, it will continue and if you have class packages they will be deducted as you take class. Whether you have classes or need to purchase them, you will need to sign up 12 hours before each scheduled class you are participating in. Once you are signed up you will receive your ZOOM link and password information needed to attend.
You will still need to create a login and password for MindBody to sign up ahead of time. Mindbody
Regular SHIFT rates apply. Rates/Packages
What If It’s My First Class?
You will need to download the ZOOM app first. You can use the ZOOM desktop app, which is available for Windows and macOS, while the mobile app is available for Android and iOS. If you have never attended SHIFT before, your first ZOOM class is FREE!
It will be most effective once you sign on to the meeting, to turn your volume all the way up so we can “chat before class” and say hello. A few minutes before class begins I will MUTE your microphones so there is no audio interference.
Make sure your device (iPhone, ipad, Laptop, or Desktop) is fully charged and plugged in. A strong Wi-Fi signal is recommended.
Shift Over
You will need a yoga mat, towel and water. Feel free to wear sneakers for better traction or barefoot. Whatever is most comfortable for you. If you have light weights, a resistance band or medicine ball feel free to use. The workout is still super effective without the props. I will give modifications as we go. If you want to purchase lightweights, a band or a small medicine ball all of these are available at Amazon.
It seems a lot of the props are out of stock or on back order, but I suggest ordering anyway as we have no idea how long this is going to last.

P-volve 2lb Hand Weights Check Amazon
Mini XerBalls (Green or Black) Check Amazon
Are You Interested?
If you’re interested and would like to find out more or schedule a class, email me at dana@shiftbydp.com. I’d like to hear from everyone!
Because you can login from anywhere in the world with Wi-Fi access, I’ve already had students join in who live throughout the United States. Feel free to invite your friends, family and associates. Visit www.shiftbydp.com.
Let’s continue to make the SHIFT forward with strength, health and community.
