Transitional economies with large geographical areas (such as Brazil, Russia, India, and China) represent both a challenge and an opportunity for the creation of spatial data infrastructures (SDI). Setting up an SDI in transitional economies is critically dependent on the diffusion of geographical information systems technology in public and private institutions. We use Rogers’ diffusion of inn...

BACKGROUND To determine the association of human papillomavirus infection (HPV) and transitional cell carcinoma (TCC). METHODS Using polymerase chain reaction, fifty-nine bladder tissue specimens of patients with transitional cell carcinoma of bladder compared with 20 bladder samples of cases with non-neoplastic disorders. RESULTS Male to female ratio was similar in the two groups (50/9 vs....

Background: The relationship between lumbosacral transitional vertebrae and low back pain is not clear. This controversy has been quite intriguing and has been the stimulus for carrying out this present study. The aim of this study was to determine, by plain radiography, if there is a relationship between lumbosacral transitional vertebrae and low back pain. Material and methods: Five hundred l...

PURPOSE To compare the expression of survivin and its association with clinicopathological criteria in major types of urinary bladder carcinoma, specifically, transitional cell carcinoma with and without squamous differentiation and squamous cell carcinoma. MATERIALS AND METHODS Immunohistochemical staining for survivin and Ki67 was performed on paraffin-embedded sections of 104 carcinomas: 5...

The late Neandertal sample from Vindija (Croatia) has been described as transitional between the earlier Central European Neandertals from Krapina (Croatia) and modern humans. However, the morphological differences indicating this transition may rather be the result of different sex and/or age compositions between the samples. This study tests the hypothesis that the metric differences between ...

OBJECTIVES To determine the perceived education and training needs of health professionals involved in transitional care for adolescents with juvenile idiopathic arthritis (JIA). METHODS Two distinct questionnaires to identify transitional issues in JIA were distributed to key health professionals (n = 908) and clinical personnel involved in the implementation of a transitional care programme...

Transitional care research has mainly focused on the experiences of older adults with complex medical conditions. To date, few publications examine the experience of transitional care for non-medically complex older adults. In this article, we draw on and thematically analyze interview and audio-diary data collected at three hospitals in Eastern England, and we explore the experience of transit...

In this paper, we study systems of two conservation laws with homogeneous quadratic flux functions. We use the viscous profile criterion for shock admissibility. This criterion leads to the occurrence of non-classical transitional shock waves, which are sensitively dependent on the form of the viscosity matrix. The goal of this paper is to lay a foundation for investigating how the structure of...

High-resolution records of the upper Olduvai geomagnetic field reversal were obtained from two localities within steeply dipping lacustrine sediments of the Confidence Hills, southern Death Valley, California . The difference in bedding attitude between the two localities allowed us to perform a fold test of both transitional and non-transitional paleomagnetic directions. This is the first posi...

Resting primordial germ cells or gonocytes, present in the testis of the rat at birth (Beaumont & Mandl, 1963), are highly radiosensitive. A dose of 50-100 r X-rays induces complete, or almost complete, sterility, as judged by the histological appearance of the testis at 25 days post par turn (Mandl et al. 1964). Studies of short-term post-irradiation changes have revealed that gonocytes, expos...
