A Comparison of the Deinkability of Certain Printing Inks
Full text linkPrinting inks differ in their composition and in their ability to be removed from paper in the deinking process. I was the purpose of this research work to make a comparison of this deinkability, for common printing inks.
In this experimentation, five inks were compared. These were a linseed oil base ink, a mineral oil base ink, a moisture set ink, a alkyd base in and a rubber base ink. Deinking was done using a standard deinking formula and varying only the concentration of the deinking agent.
The results show a marked difference in concentrations of deinking agent necessary for deinking different inks. Some of the inks deinked at low concentrations of deinking agent, while others required higher concentrations. The rubber base ink could not be deinked with the method used in this experimentation
Heightened Uncertainty and Determination: The “Trump Effect” and College Aspirations for Undocumented Students
Full text linkThis article examines the educational experiences of undocumented high school students during the Trump administration—a time marked by the intensification and expansion of immigration enforcement practices. Drawing on 24 in-depth interviews, we find that undocumented high school students experienced increased instances of bullying near the time of the 2016 U.S. presidential elections. Our respondents also worried about the growing uncertainty surrounding immigration policies and the future of DACA. This uncertainty shaped their plans; many students felt compelled to prioritize working and delay starting college to make use of their work permit while they had access to DACA and build emergency savings. While the current political climate gravely exacerbated students’ fear and anxiety, students demonstrated a tremendous amount of resiliency, agency, and determination to achieve their goals. We find that access to a support network and encouraging school personnel played a key role. Thus, we conclude this article with a set of key recommendations for educators and counselors who are working with undocumented students and their families on the ground
