Conclusions Professional veterinary accrediting standards were an important influence on the evolution of veterinary school libraries, particularly during the years of major growth in the number of new veterinary colleges in the United States and Canada. In the 1990s and beyond, both libraries and accreditation standards continue to evolve in response to changes in technology, economics, publishing methods, and more. This latter is a story yet to be told. Copyright © 2020, Authors.This study is the first to systematically identify the most recognized scholars in sociology in the 1970s and 2010s by citation counts. This is achieved on the basis of a newly generated text corpus of approximately 49,000 pages, which encompasses various genres of literature (encyclopedias, handbooks, journals, textbooks). Investigations into common characteristics reveal that, in the 1970s, elites typically received their PhD from Columbia University, Harvard University, or the University of Chicago. The contemporary elite is partly European. In general, eminence is short-lived ( less then 40 years). Over time, the elite has remained socially heterogeneous, but becomes more mobile and increasingly moves between universities. Coverage in specialist and generalist journals suggests that elite status in sociology cannot be achieved simply by dominating multiple communities inside sociology; elite sociologists are typically well received in the discipline's core. © 2019 The Author(s).

We present new characterizations for r-almost Dedekind r-SP-monoids and provide specific descriptions of t-almost Dedekind t-SP-monoids and w-SP-monoids. We show that a monoid is a w-SP-monoid if and only if the radical of every nontrivial principal ideal is t-invertible. We characterize when the monoid ring is a w-SP-domain and describe when the *-Nagata ring is an SP-domain for a star operation * of finite type. © 2019 The Author(s).

We determine the matrices for these Rota-Baxter operators by directly solving the defining equations of the operators. We also produce a Mathematica procedure to predict and verify these solutions. © 2019 The Author(s).

Background Techniques are evolving with volumetric modulated arc therapy (VMAT) commonly used. The CHHiP trial used a 3 PTV forward planned IMRT technique (FP_CH). Our centre has adopted a simpler two PTV technique with locally calculated margins. Materials and methods 25 patients treated with FP_CH to 60 Gy in 20 fractions were re-planned with VMAT (VMAT_CH) and a two PTV protocol (VMAT_60/52 and VMAT_60/48). Target coverage, conformity index (CI), homogeneity index (HI), monitor units (MU) and dose to the rectum, bladder, hips and penile bulb were compared. Results PTV coverage was high for all techniques. VMAT_CH plans had better CI than FP_CH (p ≤  0.05). VMAT_60/52/48 plans had better CI than VMAT_CH. FP_CH had better HI and fewer MU than VMAT (p ≤  0.05). More favourable rectum doses were found for VMAT _CH than FP_CH (V48.6, V52.8, V57, p ≤  0.05) with less difference for bladder (p ≥  0.05). click here Comparing VMAT_CH to VMAT_60/52/48 showed little differences for the bladder and rectum but VMAT_CH had larger penile bulb doses (V40.8, V48.6, mean, D2, p ≤  0.05). Femoral head doses (V40.8) were similarly low for all techniques (p = ≥ 0.05). Conclusion VMAT produced more conformal plans with smaller rectum doses compared to FP_CH albeit worse HI and more MU. VMAT_60/52 and VMAT_60/48 plans had similar rectal and bladder doses to VMAT_CH but better CI and penile bulb doses which may reduce toxicity. Crown Aim We conducted a study to validate the MDASI-HN based nomogram, which is used to predict the acute toxicities in head and neck cancer patients undergoing radiation therapy with or without chemotherapy. Background Tolerance to radiation varies from patient to patient and also depends on various other factors like tumor volume, dose of radiation, chemotherapy. Predicting the toxicities allow us to identify potential candidates who are likely to have a higher toxicity and, in addition, evaluates the nomogram when done on an independent group of patients. Materials and Methods Sixty biopsy confirmed head and neck cancer patients undergoing radiation were the subjects of the study. The patients completed patient reported outcome instrument (PRO) MDASI-HN questionnaire at the beginning and at the fifth week of radiation. The baseline score obtained was used to obtain the predicted score using nomogram. The nomogram was also externally validated as per the TRIPOD guidelines. Results The mean baseline, predicted and score at the fifth week were 27.28 ± 11.04, 73.33 ± 15.51 and 82.62 ± 17.67, respectively, for all sub-sites. A positive, significant correlation (p  less then  0.01) between the predicted score and the score at the fifth week was seen across all sub sites such as Oral cavity (p = 0.05), Oropharynx (p = 0.02), Hypo pharynx (p = 0.02) and Larynx (p = 0.02). Conclusion The MDASI-HN questionnaire based nomogram is simple, easily doable and takes into consideration the initial symptoms as well the treatment details; thereby, it is able to predict the toxicities accurately. © 2020 Greater Poland Cancer Centre.

These tumors are rare and only make bone metastases at a rate of 5%. Case summary A 31-year-old male with a GIST presented with solitary bone metastasis at the right iliac bone. We performed stereotactic ablative radiotherapy (SABR) and achieved excellent local control. Herein, our case is presented, and a short review of the literature is carried out. Conclusion SABR should be considered as a treatment option in GIST with bone metastasis. © 2020 Greater Poland Cancer Centre. Published by Elsevier B.V. All rights reserved.
