We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

8. Odd and Even Numbers
Addition
Subtraction
even + even = even even – even = even
Multiplication
even . even = even
odd + odd = even
odd – odd = even
odd . odd = odd
even + odd = odd
even – odd = odd
even . odd = even
odd +even = odd
odd – even = odd
odd . even = even
11. Divisibility and Remainders
All whole numbers are divisible by 1.
A number that ends in an even digit is divisible by 2.
A number is divisible by 3 if its digits add up to a number divisible by 3.
For example, 384 is divisible by 3 because 3 + 8 + 4 = 15, and 15 is
divisible by 3.
A number is divisible by 4 if its last two digits are divisible by 4. The
number 5,764 is divisible by 4 because 64 is divisible by 4.
A number is divisible by 5 if it ends in 0 or 5.
A number is divisible by 6 if it is even and divisible by 3. This rule is a
combo of rules 2 and 3.
Sadly, there is no rule for 7.
A number is divisible by 8 if its last three digits are divisible by 8. For
example, 1,249,216 is divisible by 8 because 216 is divisible by 8.
A number is divisible by 9 if its digits add up to a number divisible by 9.
The number 2,952 is divisible by 9 because 2 + 9 + 5 + 2 = 18.
A number is divisible by 10 if it ends in 0.
13. Divisibility and Remainders: Squares
0 -> then the ending digit is a 0
1 -> then the ending digit is 1 or 9.
4 -> then the ending digit is 2 or 8.
5 -> then the ending digit is a 5.
6 -> then the ending digit is 4 or 6.
9 -> then the ending digit is 3 or 7.
C. After finding the last digit (or possibility between two digits) mentally chop off the last
two digits and focus on the remaining digits.
14. Example 1:
Q) The number n is a 2 digit integer. When n is divided by 5
it leaves a remainder of 4 and when n is divided by 9, it leaves
a remainder of 7. What is the value of n?
15. Strategies
1a) Picking Numbers
Step 1. Pick Simple Numbers and substitute for variables.
Step 2. Try Them Out
Try out all the answer choices using the numbers you picked,
eliminating those that gave you a different result.
Step 3. Try Different Values
If more than one answer choice works, use different values
and start again
1b) Recognition by prolonged and multiple use of Picking
Numbers
18. 2) Back-solving
Step 1: Estimate the answer.
Step 2: Plug in an answer.
Step 3: Keep plugging in till you find one that works.
Step 4: Try out all answers.
Q. If x is an integer and 2 is the remainder when 3x +
4 is divided by 5, then x could equal
(A) 3
(B) 4
(C) 5
(D) 6
(E) 7
