Seven models for tendon repair simulation (urinary catheter, liquorice, fishing lure, dental rolls, drinking straw, silicone sealant and the authors’ modification of silicone sealant with Micropore™ tape) were assessed for their performance in a number of domains. The silicone sealant and surgical tape model scored highest overall and for each individual domain. This was significantly higher than all other models with the exception of the silicone sealant alone. The lowest scoring model was the drinking straw model.

Urinary catheter insertion is one of the most widely performed procedures in a clinical setting. Inexperienced cath- eterizations constitute a high percentage of urethral trauma in hospital settings, with as high as 75% of comorbidities related to inaccurate insertion. Simulation training can help learners feel more confident, shorten the learning curve, and provide a safe learning environment for novices to make, and learn from, mistakes. Three dimensional (3D)- printed simulation models are as effective as commercially available models for novice learners, and have the benefits of being inexpensive, anatomically correct, portable and can be easily modified and rapidly produced as needed. A 3D-printed male urinary catheter insertion simulation model, designed by MUNMed 3D, was offered to Memorial University medical students as part of pre-clerkship procedural training. Fourteen students were provided with a checklist for the procedure and the 3D-printed urinary catheter insertion simulator, and following the simulation, were asked to complete a 5-point Likert survey on their experience.The average self-reported skill before using the model was 1.29 (out of 5), which increased to 3.21 (out of 5). All 14 respondents selected either “agree” or “strongly agree” for the following four survey items: the simulation was an accurate anatomical representation, they would prefer learning on this simulation model before performing this procedure, they would recommend the model to other learners, and they found this model beneficial overall. Simulation training with a 3D-printed urinary catheter insertion simulator allows trainees the opportunity to become confident and familiarize themselves with the procedure before performing it on a real patient.

“Hydropic degeneration” of the hepatocytes are often found in biopsy of the liver of some kinds of viral hepatitis. Light microscopic observation, compareted with the normal hepatocytes, they are enlarged, sometimes to a marked degree when the term “balloning” degeneration is used. Their cytoplasm rarefied, and show some clearness in the peripheral cytoplasm, so, it causes a hydropic appearance, the cytoplasm around the nuclei is granulated. Up to the present, many studies belive that main ultrastructural chenges of hydropic degeneration of the hepatocytes are results of the RER cristae dilatation with degranulation and disappearance of glycogen granules.The specimens of this study are fixed with the mixed fluid of the osmium acidpotassium of ferricyanide, Epon-812 embed. We have observed 21 cases of biopsy specimens with chronic severe hepatitis and severe chronic active hepatitis, and found that the clear fields in the cytoplasm actually are a accumulating place of massive glycogen. The granules around the nuclei are converging mitochondria, endoplasm reticulum and other organelles.

The geometric structure of pore space in some carbonate rocks can be correlated with petrophysical measurements by quantitatively analyzing binaries generated from SEM images. Reservoirs with similar porosities can have markedly different permeabilities. Image analysis identifies which characteristics of a rock are responsible for the permeability differences. Imaging data can explain unusual fluid flow patterns which, in turn, can improve production simulation models.Analytical SchemeOur sample suite consists of 30 Middle East carbonates having porosities ranging from 21 to 28% and permeabilities from 92 to 2153 md. Engineering tests reveal the lack of a consistent (predictable) relationship between porosity and permeability (Fig. 1). Finely polished thin sections were studied petrographically to determine rock texture. The studied thin sections represent four petrographically distinct carbonate rock types ranging from compacted, poorly-sorted, dolomitized, intraclastic grainstones to well-sorted, foraminiferal,ooid, peloidal grainstones. The samples were analyzed for pore structure by a Tracor Northern 5500 IPP 5B/80 image analyzer and a 80386 microprocessor-based imaging system. Between 30 and 50 SEM-generated backscattered electron images (frames) were collected per thin section. Binaries were created from the gray level that represents the pore space. Calculated values were averaged and the data analyzed to determine which geological pore structure characteristics actually affect permeability.

Background American educational legislation suggests culturally competent speech and language services should be provided in a child's native language, but the number of multilingual speech-language pathologists (SLPs) is negligible. Consequently, many monolingual English-speaking practitioners are being tasked with providing services to these populations. This requires that SLPs are educated about cultural and linguistic diversity as well as the legislation that concerns service provision to non-English or limited English proficiency speakers. Purpose This qualitative study explored the experiences of monolingual, American, English-speaking SLPs and clinical fellows who have worked with immigrant and refugee families within a preschool context. It investigated what training SLPs received to serve this population and what knowledge these SLPs possessed with regard to federal legislation governing the provision of services to culturally and linguistically diverse (CLD) communities. Method Ten American clinicians with experience treating CLD children of refugee and immigrant families in the context of preschool service provision participated in the study. Semistructured interviews were utilized to better understand the type of training clinicians received prior to and during their service delivery for CLD populations. Additionally, questions were asked to explore the degree to which practitioners understood federal mandates for ethical and effective service provision. The data collected from these interviews were coded and analyzed using the principles of grounded theory. Findings The results of this study revealed that there was a general sense of unpreparedness when working with CLD clients. This lack of training also attributed to a deficiency of knowledge surrounding legislation governing service provision to CLD populations.

Abstract This qualitative study examined student perceptions regarding a hybrid classroom format in which part of their learning took place in a traditional classroom and part of their learning occurred in an online platform. Pre-course and post-course anonymous essays suggest that students may be open to learning in this context; however, they have specific concerns as well. Students raised issues regarding faculty communication patterns, learning styles, and the value of clear connections between online and traditional learning experiences. Student concerns and feedback need to be addressed through the course design and by the instructor in order for them to have a positive learning experience in a hybrid format course.

There is a growing demand for bilingual services in speech-language pathology and audiology. To meet this growing demand, and given their critical role in the recruitment of more bilingual professionals, higher education institutions need to know more about bilingual students' impression of Communication Sciences and Disorders (CSD) as a major. The purpose of this qualitative study was to investigate bilingual and monolingual undergraduate students' perceptions of the CSD major. One hundred and twenty-two students from a large university located in a highly multicultural metropolitan area responded to four open-ended questions aimed at discovering students' major areas of interest (and disinterest) as well as their motivations for pursuing a degree in CSD. Consistent with similar reports conducted outside the United States, students from this culturally diverse environment indicated choosing the major for altruistic reasons. A large percentage of participants were motivated by a desire to work with children, but not in a school setting. Although 42% of the participants were bilingual, few indicated an interest in taking an additional course in bilingual studies. Implications of these findings as well as practical suggestions for the recruitment of bilingual students are discussed.
