Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.

This document discusses problems from the 9th International Physics Olympiad held in Budapest, Hungary in 1976. It presents three theoretical problems and one experimental problem. The first theoretical problem involves calculating the minimum coefficient of friction needed to prevent a block from slipping inside a rotating hollow sphere. The second problem calculates the work done on a piston by compressing gas in an insulated cylinder. The third problem describes methods for determining the diameter of an air bubble inside a glass sphere without damaging it. The experimental problem involves using heating and time-temperature graphs to determine unknown thermal properties of a crystalline substance.
The rate of heat flow through both rods is the same.
dT/dx is constant along each rod.
dT/dx along D = dT/dx along E
(100-80)/0.2 = (T-80)/0.4
T = 120 °C
Therefore, the temperature at the free end of rod E is 120 °C.

The passage discusses Deborah Mayo's philosophy of science, which focuses on rigorously validating claims made through experimentation. According to Mayo, a claim can only be considered supported by an experiment if the experiment investigates and eliminates all possible ways the claim could be false. For an experiment to serve as a severe test of a claim, the claim would have to be unlikely to pass the experiment if it were false. The passage provides examples to illustrate this point, such as how imprecise measurements of Snell's law of refraction would allow alternative historical laws to also seem consistent with the experimental results, demonstrating the experiment was not a true severe test of Snell's law.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
