Take This, It\u27s Free: Public Domain Clearance Project at Texas A&M University-Commerce Libraries
No full textCopyright law in the United States is notoriously complex. To aid researchers at the Texas A&M University Commerce Libraries in discerning copyright status more clearly, archivist Michael Barera and digital collections librarian Adam Northam developed a project in 2016 to identify images that have entered the public domain from our Historic East Texas Collection, which documents university history

No full textLearn to Edit Wikipedia Workshop
No full textThis two-hour session will cover the basics of editing Wikipedia. Michael Barera, a Wikipedian with 13 years of experience, will give a presentation on the basics (including creating an account, editing text, creating references, and adding images) at the beginning and again one hour into the session. He will spend the rest of the time working one-on-one with participants, allowing everyone who attends the ability to work at their own pace and learn skills particular to their interests
A Walk through the Wikiverse
No full textJoin the UT Arlington Libraries during Open Access Week for a venture into Wikipedia. Wikipedia is often the place where research begins on the internet. It is ranked 5th in overall global web traffic. Its mission is to provide free access to knowledge. With over 30 million articles written in 286 languages, Wikipedia generates approximately 8000 views per second from 500 million monthly visitors. How can libraries, staff, and faculty leverage the power of Wikipedia and turn this tool into an interactive learning opportunity for students and the community? Listen to Michael Barera and then stay for a lunch panel presentation on Wikipedia in the Classroom

Evaluating the presence of human pathogens in commercially frozen, biologically appropriate raw pet food sold in Italy
No full textBackground: Biologically appropriate raw food (BARF) diet is becoming more and more popular among pet owners in Europe. However, there are documented microbiological risks associated with raw feeding, and this study aimed to determine the presence of human pathogens in commercially frozen BARF products sold in Italy. Methods: Salmonella species, Escherichia coli O157:H7, Listeria monocytogenes and Campylobacter species were identified. The general microbiological quality of BARF products and hygiene were also evaluated. Sample size was limited and therefore the study may not be representative of a larger sample. Results: None of the tested samples showed total bacterial count (TBC) higher than the limit set to consider a sample unacceptable. However, 14 out of 21 samples showed TBC higher than the limit set to consider a sample marginally acceptable. A high percentage of samples were contaminated by the aforementioned pathogens, highlighting the need for pet owners to be aware of the risks of this feeding strategy both to themselves and to their pets. Conclusions: Considering that BARF diet meals can be prepared at home using the hands, as well as tools and spaces that could be shared, guidelines on safer handling of these pet food products should be recommended by veterinarians and nutritionists
Proteomic characterization and three-dimensional electron microscopy study of PSII-LHCII supercomplexes from higher plants
No full textIn higher plants a variable number of peripheral LHCII trimers can strongly (S), moderately (M) or loosely (L) associate with the dimeric PSII core (C 2) complex via monomeric Lhcb proteins to form PSII-LHCII supercomplexes with different structural organizations. By solubilizing isolated stacked pea thylakoid membranes either with the α or β isomeric forms of the detergent n-dodecyl-D-maltoside, followed by sucrose density ultracentrifugation, we previously showed that PSII-LHCII supercomplexes of types C2S2M2 and C2S2, respectively, can be isolated [S. Barera et al., Phil. Trans. R Soc. B 67 (2012) 3389-3399]. Here we analysed their protein composition by applying extensive bottom-up and top-down mass spectrometry on the two forms of the isolated supercomplexes. In this way, we revealed the presence of the antenna proteins Lhcb3 and Lhcb6 and of the extrinsic polypeptides PsbP, PsbQ and PsbR exclusively in the C2S2M2 supercomplex. Other proteins of the PSII core complex, common to the C2S 2M2 and C2S2 supercomplexes, including the low molecular mass subunits, were also detected and characterized. To complement the proteomic study with structural information, we performed negative stain transmission electron microscopy and single particle analysis on the PSII-LHCII supercomplexes isolated from pea thylakoid membranes solubilized with n-dodecyl-α-D-maltoside. We observed the C2S 2M2 supercomplex in its intact form as the largest PSII complex in our preparations. Its dataset was further analysed in silico, together with that of the second largest identified sub-population, corresponding to its C2S2 subcomplex. In this way, we calculated 3D electron density maps for the C2S2M 2 and C2S2 supercomplexes, approaching respectively 30 and 28 Å resolution, extended by molecular modelling towards the atomic level.
