3D treatment changes in alveolar bone thickness around the mandibular incisors

The limit of mandibular incisor correction is dependent on the amount of crowding and the incisor position within the mandibular alveolar bone. Moving teeth outside of the alveolar bone can have detrimental effects on the periodontium. The purpose of this study was to evaluate in 3D incisor angulation, B point, root apex position changes, facial and lingual cortical bone thickness at four levels on each tooth, and 2D lower incisor angulation to the true vertical plane and intercanine width changes. Pre- and post-treatment Cone Beam Computed Tomography images of 67 orthodontic patients were included from the BU repository. 276 mandibular incisors and 138 canines were evaluated. A mandibular plane was used as a horizontal reference plane. 3D measurements of angular changes in apex to constructed Menton plane for all four lower incisors increased by a statistically significant amount. (p<0.0001) Intercanine width (p=0.0032), arch length discrepancy (p<0.0001) incisor angulation for each incisor also showed statistically significant differences (mean change 2.3°, mean p=0.009). Changes in L1-NB were also found to be statistically significant (p < 0.005). Incisor bone thickness changes were statistically significant. Lingual bone change in LL1 at point A, was –0.18 mm, p=0.0072: at point B, -0.38, p<0.0001: at point C, -0.56, p<0.0001: at apex point -0.65 mm, p<0.0001. Similar lingual bone thickness changes were noted for all incisors. The results show that lingual bone loss increased from superior reference point (A) to apex, suggesting that roots are tipped around the center of resistance

Brewer\u27s Spent Grain to Xylitol & Polylactic Acid

With this project, the authors seek to present a desirable and novel process for converting brewers’ spent grain into two value-added products: the alternative sweetener, xylitol, and a biodegradable plastic, polylactic acid. This particular process is based in the Philadelphia Naval Yard, and uses the spent grain from surrounding breweries and microbreweries as its input. However, while the collection logistics and input quantity may change, the process is one that may be implemented anywhere, with varying degrees of success. The process consists of collection, universal pretreatment, then a split to feed one of two continuous fermenters. A highly acidophilic strain of the yeast Candida tropicalis ferments xylose into xylitol, which is then purified and pelleted in a marketable state. Lactobacillus delbrueckii bacteria ferments glucose into lactic acid, which is then polymerized to form polylactic acid of the desired molecular weight. This polymer is then purified and processed for sale. This product profile is optimal, as it incorporates both of the major constituents of the grain – cellulose and hemicellulose. Under the current market conditions, this process is expected to be financially desirable. We estimate a return on investment of 25.5%, with an internal rate of return of 30.95% and a net present value of $34.5M by 2032. However, if the price of polylactic acid were to rise, as market patterns suggest it may, this process could quickly become even more profitable. We therefore recommend pursuing the proposed process, and possibly expanding to other densely populated areas

Inclusion and Equity Committee Recommendations for Diverse Recruitment Report

The UNLV University Libraries Inclusion and Equity Committee (IEC) developed the Diverse Recruitment project in order to fulfill its charge in supporting the Libraries’ commitment to increasing representation and retention of historically underrepresented groups at all levels of staff. These recommendations draw upon a range of best practices, procedures, and programs. Largely informed by Duke University’s February 2018 Task Force for Diversity in Recruitment Report, three task forces each investigated a different aspect of understanding diverse recruitment as it related to the Libraries. These results were synthesized into a series of recommendations for the Libraries’ Leadership Team (LLT) and the Libraries to consider implementing

Where to Start? Developing a Metadata Management Lifecycle

Metadata management–the process of establishing policies and processes to ensure metadata can be integrated, accessed, shared, linked, analyzed, and maintained–is essential for supporting our users, as well as our own institutional needs. With so many tools available to catalogers and metadata workers, it can be difficult to keep up, or even know where to start to accomplish a project. Other fields in librarianship, such as research data management, digital library development, and digital preservation have clear process models to guide new practitioners. Whether creating metadata for newly acquired material, or trying to adapt metadata created outside of a particular metadata standard for use in a different system, there is not always a clear-cut methodology for where or how to get started outside of metadata standards. In this presentation, the presenters will break down their model for engaging in metadata management, resolving metadata issues, and exploring options for metadata remediation/reconciliation
