1. The document describes an experiment involving electrochemical and galvanic cells. It involves assembling half-cells of Cu2+ and Zn2+ solutions with copper and zinc electrodes, and measuring the voltage.
2. A galvanic cell is then assembled by connecting the half-cells with a salt bridge, and the voltage is measured for combinations of Zn/Zn2+, Cu/Cu2+, and Pb/Pb2+ electrode pairs.
3. The observed voltages are compared to theoretical standard electrode potentials to calculate percentage error. The document also discusses using fruit instead of a salt bridge and cautions against eating the fruit afterwards.
The OSS Simple Sabotage Field Manual was published by the Office of Strategic Services in 1944.
The document details methods for sabotaging productivity, many of which are now technologically obsolete. However, others relate to organizational inefficiency and have proven to be timeless.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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”.

Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
Model Attribute Check Company Auto PropertyCeline George
In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Objective:
Procedure:
A. L Add 0.5 M Cu(N03) 2 to the porous cup until it is about halffull. Plac~ a clean strip of copper in the I
cup. Connect the copper electrode to the positive terminalofthe voltmeter. I
2. Add 0.5 M Zn(N0 3)2 to the I SOml beaker until it is about 1/3 full. Place a clean strip of zinc in the f.
beaker. Connect the zinc electrode to the negative terminal of the voltmeter.
3. Note the voltage reading of the half cells.
4. Place the porous cup in the beaker. Note the voltage reading. Remove the porous cup and return all
the solutions and metal electrodes.
B. I. Assemble a galvanic cell by coupling 2 test electrodes. Dip one end of the salt bridge in one of the
half cells and the other end to the second half cell. The salt bridge is thread soaked in a supersaturated
/.
I KCI. The galvanic ells to be assembled involve the following pairs of electrodes:
• a) Zn/Zn 2+ electrode and Pb/Pb 2+ electrode
2+ 2+ .
b) Cu/Cu electrode and Zn/Zn electrode
~i c) Cu/Cu 2+ electrode and Pb/Pb 2+ electrode
.t
..... i 2. Connect each electrode to the input terminals of the voltmeter and read the voltage. If a negative
I voltage is observed, interchange the terminat'connections. Note the terminal to each electrode is
connected. The cathode is the half cell connected to the positive (red) terminal of the meter, and the
I
anode is the half cell connected to the negative (black) terminal. .
