An analysis of MLA Exchange material shipped as well as received is presented. It was found that, of 10,382 items shipped during a twelve-month period to 588 libraries, 332 of these mailings, or 56 percent, were sent for ten cents or less, at a total of $24.80 for postage, an average of $6.20 per exchange list. Similarly, a six-month log of items received by the library shows that 55 percent of these mailings was sent to the library for ten cents or less. The results of this study suggest that the waiving of small fees could eliminate more than half of the donor library's record keeping on postal reimbursements and that it could cut the receiving library's actual reimbursement cost, which is shown to reach 250 percent.

Study on the occurrence characteristics of arsenic in copper matte.

Sci Rep

November 2024

College of Environmental and Resources, Xiangtan University, Xiangtan, 411105, China.

Article Synopsis
  • The study investigates the presence and behavior of arsenic in the matte phase, which is crucial for improving treatments to reduce arsenic contamination in copper smelting processes.
  • Instrumental techniques like XRD and SEM-EDS were used to identify that arsenic mainly exists as sulfides, oxides, and alloy compounds in matte, with most being in a stable, residual form.
  • The strong metal bond between copper and arsenic in matte compounds makes it challenging to separate arsenic, complicating efforts to eliminate it from the smelting process.

Introduction: Non-native-speaking nursing students as well as faculty, preceptors and mentors face specific issues related to language in undergraduate nursing education. A better understanding of the language experiences, needs, requirements, assessments and support activities will guide linguistically responsive learning and teaching and will direct future curriculum development. This scoping review aims to examine and map the extent of literature related to linguistically responsive learning and teaching for non-native speakers in undergraduate nursing education and to describe the lived experiences, barriers and facilitators, language needs, assessment tools and supportive interventions.

The Maintenance of Lipid Asymmetry (Mla) pathway is a multicomponent system found in all gram-negative bacteria that contributes to virulence, vesicle blebbing and preservation of the outer membrane barrier function. It acts by removing ectopic lipids from the outer leaflet of the outer membrane and returning them to the inner membrane through three proteinaceous assemblies: the MlaA-OmpC complex, situated within the outer membrane; the periplasmic phospholipid shuttle protein, MlaC; and the inner membrane ABC transporter complex, MlaFEDB, proposed to be the founding member of a structurally distinct ABC superfamily. While the function of each component is well established, how phospholipids are exchanged between components remains unknown.

In endovascular therapy (EVT) for femoropopliteal artery (FPA) lesions, studies examining the relationship between lesion morphology and hemodynamic status are limited. The purpose of this study was to investigate FPA lesion characteristics, including imaging findings and their cutoff values that can predict hemodynamic significance after balloon angioplasty. This single-center retrospective study enrolled 50 de novo FPA lesions from 43 patients treated under intravascular ultrasound (IVUS) usage between June 2022 and March 2023.
