Why does my library account say that I am blocked, that I am barred, or that my status is expired?
Users can encounter several different types of status messages. Patrons with questions about their account status can visit the checkout desk in room 241 of LSU Library and ask to speak to a staff member. Alternatively, patrons can reach out to us via e-mail at libcirc@lsu.edu (mailto:libcirc@lsu.edu) . When contacting us via e-mail, LSU students, staff, and faculty should message us from their LSU e-mail address; public patrons should message us from the e-mail address we have on file. For privacy reasons, we cannot discuss the details of patron accounts over the telephone. Expired: Students must be currently enrolled in classes in order to be granted library privileges. Once they graduate, or if they fail to register on time in accord with the deadlines posted on LSUs academic calendar, their privileges expire. If they try to log in to their library account after that date, they will see an alert message informing them that their account has expired. Graduate students who have received a masters degree but are continuing on to get their PhD may also have their privileges expire earlier than expected. The library receives weekly updates on student status from the Registrars Office. Once the semester has begun, if students register during the week, their accounts will not be updated and their privileges extended in the system until the following Monday morning. Blocked: Users with overdue recalled books will have their accounts blocked by the system. Their accounts will remain blocked until the book is returned. The system will not permit staff members to override blocks or to renew books that have been recalled. The only way to remove a block from an account is to return the materials. Barred: Users can be barred from using library materials for a number of reasons, the most common being that they have been billed for lost items. They can also be barred if they resign from the university, if their classes are purged, or for flagrant violations of library policy. If they try to log into their account after they have been barred, they will receive an alert message that tells them that they have been barred. Answered by: Access Services Staff

Scalable and Sustainable DMF-Free Solid-Phase Synthesis of Liraglutide by 1-Tert-Butyl-3-Ethylcarbodiimide-Mediated Couplings and Catch-and-Release Acylation and Purification Strategies
Introduction: The growing need for sustainable practices in pharmaceutical manufacturing has stimulated advancements in peptide synthesis. This study focuses on applying green chemistry principles to the synthesis of the Glucagon-Like Peptide-1 analog liraglutide.Material and Methods: The safer coupling reagent 1-tert-butyl-3-ethylcarbodiimide (TBEC) was tested in combination with eco-friendly binary solvents such as dimethyl sulfoxide and butyl acetate to propose novel and sustainable solid-phase synthetic and purification strategies of liraglutide.Results: Two synthetic strategies were developed for liraglutide production. The first strategy was based on a “direct synthesis”, incorporating a lipidated lysine building block into the peptide sequence, achieving 86% HPLC purity after catch-and-release purification. The second strategy based on “catch-lipidation-and-release” approach, allowed to obtain the peptide precursor without the lipid moiety, which was later linked during a controlled lipidation step. This latter strategy yielded purities exceeding 90% and reduced reliance on preparative HPLC. TBEC minimizes hazardous byproducts, such as hydrogen cyanide, and enhances solvent compatibility, achieving crude purities and yields comparable to conventional syntheses.Conclusion: This work underscores the potential of green chemistry to align pharmaceutical innovation with environmental responsibility. In particular our findings highlight the effectiveness of TBEC and green solvent systems optimizing scalable and sustainable SPPS processes and improving resource efficiency. Thus, we propose a viable pathway to produce the therapeutic peptide ingredient liraglutide significantly reducing the environmental impact while maintaining high efficiency and quality of the synthesis.
Alaskan Catch
A dream job it's not. But for Emily Prentice, working as a seafood inspector in Ketchikan, Alaska, takes her one step closer to becoming a marine biologist. And it'll give her a first taste of independence from her overprotective mom and the doctor boyfriend she's pushing into Emily's arms. Emily's certainly not looking for romance... until a huge dog knocks her down and sends her flying into fish goo. It's love at first sight for Emily and Bear, whose handsome owner, Sam, becomes flummoxed when the fallen worker in the hard hat turns out to be a pretty young woman. Emily and Bear begin a beautiful relationship, with Sam in tow. And before long the attraction between the humans becomes undeniable. But separation and a dangerous undertaking soon leave Emily wondering if she'll lose Sam before she gets to tell him how she really feels... Bear wants his humans staying together, and before he's done, both Emily and Sam will learn one essential canine truth: A dog is the only one on earth who loves you more than you love yourself.Praise for Sue Pethick's Novels “Quirky characters abound in this gentle romantic comedy with a hint of suspense.
