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.

Waterway Analysis
Purpose The Design Storm: SCS Type II HydroCAD
In 2008, a grassed waterway was constructed 10–year, 24–hour storm The Stormwater Modeling Software, HydroCAD, uses hydrology
principles that were developed by the NRCS as well as various
to transport flows from an upstream hydraulic calculations. It uses the TR-55 method for calculating Time
watershed, through the AARS Organic Corner of Concentration (tc) values and gives unique hydrographs through
waterways, ponds, culverts and various other hydraulic components.
(denoted with blue arrows in Figure 3).
Because of the immediate need for the
channel, a proper engineering design was not
carried out. In order to verify that this
waterway was adequately built, HydroCAD
was used to model the watershed and
waterway.

Q = 2.0 ft3/s (determined from HydroCAD)
Waterway Vpermissible = 1.5 - 5 ft/s
In evaluating the waterway it was determined A = 3.5 ft2
that the current channel will be sufficient to S=2%
handle the peak flow from a 10 yr – 24 hour
storm event. This determination was made
primarily using the results from the
HydroCAD model.
Erosion Control
After Conversations with the Arlington
Research Station staff a modified plan was
devised. The impact of this proposed plan on
erosion rates can be seen in Table 1. Figure 2: Proposed Terrace Cross
