The United States Department of Agriculture (USDA) beef grading system plays an important role in marketing and promoting beef. USDA graders inspect beef carcasses and determine a quality grade within a few seconds. Although the graders are well-trained, the nature of this grading process may lead to grading errors. Significant differences in the USDA graders’ ‘called’ and ‘camera-graded’ quali...

Aim: To find out utility of grading breast carcinoma on fine needle aspiration (FNA) as per the criteria proposed by Robinson and Colleagues and compare it with histological grading proposed by Elston and Ellis based on method by Nottingham’s modification of Bloom and Richardson system. Methods: Cytological smears of 58 cases of breast carcinoma diagnosed on fine needle aspiration cytology (FNA...

A contour sub-division algorithm on each layer arising from slicing a heterogeneous object is proposed. Within each slice, the material grading is decomposed into subcontours according to the different grading variation. A parameter called “grading step-width” is defined to control the number of sub-contours and resolution of the grading. With such discretization, it is, therefore, possible to ...

Standards-based grading, in which grading should be designed to communicate to students their current level of mastery with regards to well-articulated standards, is becoming popular at the K-12 level. As yet, the literature addressing standards-based grading at the university level is scarce. In this paper, I document my attempts to put into practice the principles of standards based grading i...

We investigated mesoto bathypelagic (500–3,000 m) bacterioplankton assemblage composition at 19 locations in the North Atlantic Ocean beneath the offshore Amazon River plume, in the North Pacific Ocean near the Hawaiian archipelago, at the San Pedro Ocean Time Series (SPOTS) station off southern California, and in the Coral Sea off eastern Australia with a sensitive high-throughput fingerprinti...

A robust and automatic system has been developed to detect the visual axis and extract important feature landmarks from slit-lamp photographs, and objectively grade the severity of nuclear sclerosis based on the intensities of those landmarks. Using linear regression, we first select the features that play important roles in classification, and then fit a linear grading function. We evaluated t...

Grading of agricultural produce especially the fruits and vegetables has become a perquisite of trading across borders. In India mostly fruit and vegetable growers grade the fruit manually. Manual grading was carried out by trained operators who considered a number of grading factors and fruit were separated according to their physical quality . Manually grading was costly and grading operation...

A 60-year-old man with renal cell carcinoma developed lung metastases after treatment with left radical nephrectomy (pT3bN0M0, clear cell renal carcinoma, Fuhrman G3 >2). The patient received treatment with gemcitabine and interferon-α and achieved complete response after seven cycles of therapy. However, eight months later, local recurrence was discovered in the renal fossa. We changed the the...

We present a case of an ectopic renal tumor in a 61-year-old morbidly obese man with a pelvic kidney found after presenting with hematuria and irritative voiding symptoms. The mass, along with the ectopic kidney and ureter, was radically resected through an open operation that involved removing both them and the renal vessels from the underlying iliac vessels. Pathological analysis demonstrated...
