with respect to the physical and mechanical limited qualities of bitumen, it benefits from certain specificability in application and its life service. polymers as the most important modifiers of bitumen are applied to it in order to improve its functional efficiency. among various polymers, styrene-butadiene- styrene (sbs) is the best modifier of the bitumen. in this work, sbs polymer as one o...

OBJECTIVE Adaptation of the Clavien-Dindo classification for assessing the severity of complications following the endoscopic treatment of nephrolithiasis and evaluation of its versatility and objectivity. MATERIAL AND METHODS We retrospectively reviewed the medical records of 1027 patients who presented stones located in upper urinary tract (597 males, 58.1% and 430 females, 41.9%), mean age...

conclusions our study revealed weak correlation between pe/e-vc and cormack-lehane grade, with 87% sensitivity and 30% specificity. therefore, we concluded that sonographic measurement criteria are not accurate in airway evaluations before anesthesia. results it was observed that correlations between the pre-epiglottic space (pe) and cormack-lehane grades i, ii, and iii were weak. correlations ...

BACKGROUND It is helpful in planning treatment for patients with ductal carcinoma in situ (DCIS) if the size and grade could be reliably predicted from the mammography. The aims of this study were to determine if the type of calcification can be best used to predict histopathological grade from the mammograms, to examine the association of mammographic appearance of DCIS with grade and to asses...

Glioma grading and classification, today based on histological features, is not always easy to interpret and diagnosis partly relies on the personal experience of the neuropathologists. The most important feature of the classification is the aimed correlation between tumor grade and prognosis. However, in the clinical reality, large variations exist in the survival of patients concerning both g...

Ovarian carcinomas of epithelial type comprise a heterogeneous group of neoplasms, each with a different underlying pathogenesis and natural behaviour. Accurate classification of ovarian carcinomas is important since each type may be associated with a different behaviour, natural history and outcome. Precise classification is also critical to determine whether alternative therapeutic strategies...

OBJECTIVES To determine the prevalence of tibiofemoral radiographic knee osteoarthritis (OA) in people aged 35-54 years associated with chronic (> 3 months) knee pain using two different radiographic grading systems. METHODS Population based postal survey in a random sample of inhabitants in a district in southern Sweden followed by clinical examination and plain posteroanterior, weight beari...

Objective: The aim of this study was to find out the prevalence of protein energy malnutrition(PEM) by anthropometric measurements in preschool children of tribal community of Chhattisgarh. Material and Methods: A total of 449 children [237 boys and 212 girls] from 286 families were selected randomly. Anthropometric measurements were done as per standard protocol. The level of underweight, stun...

This paper proposes an adaptive method to construct a fuzzy rule-based classification system with high performance for pattern classification problems. The proposed method consists of two procedures: an error correction-based learning procedure and an additional learning procedure. The error correction-based learning procedure adjusts the grade of certainty of each fuzzy rule by its classificat...

BACKGROUND Thymic neuroendocrine tumor (carcinoid tumor) is rare, and prognosis for patients with this tumor has been difficult to predict. METHODS The medical records of 15 patients were reviewed, and the patients were classified according to tentative TNM classification and histologic grade. RESULTS Ten (66.7%) of 15 patients were male. Lymph node metastases were identified in 9 (60%) of ...
