1. Primary renal angiosarcoma with extensive hemorrhage: CT and MRI findings
ABSTRACT Primary angiosarcomas of the kidney are very rare, but highly aggressive tumors showing poor prognosis. Patients frequently complain of flank pain, hematuria, or a palpable mass. We present a case of primary renal angiosarcoma occurring in a 61-year-old man. CT images depicted a huge exophytic mass (16 cm in diameter) in the right kidney, exhibiting

2. A novel discussion on centripetal force
Abstract In order to enrich the field of Newtonian mechanics, some novel approaches for the derivation of the expression for the centripetal force have been offered in this paper. The paper starts with a lucid and easily readable discussion of how the centripetal force arises when a particle undergoes uniform circular motion and it ends with a systematic pre

3. Characterisation of the vascular pathology in Sigmodon hispidus (Rodentia: Cricetidae) following experimental infection with Angiostrongylus costaricensis (Nematoda: Metastrongylidae)
BACKGROUND Angiostrongylus costaricensis is a nematode that causes human abdominal angiostrongyliasis, a disease found mainly in Latin American countries and particularly in Brazil and Costa Rica. Its life cycle involves exploitation of both invertebrate and vertebrate hosts. Its natural reservoir is a vertebrate host, the cotton rat Sigmodon hispidus. The

4. A Modified FEM for Transverse and Lateral Vibration Analysis of Thin Beams Under a Mass Moving with a Variable Acceleration
Abstract In this paper, a new modified finite element method that can be used in the analysis of transverse and lateral vibrations of the thin beams under a point mass moving with a variable acceleration and constant jerk is presented. Jerk is the change in acceleration over time. In this method, the classical finite element of the beam is modified by the in

5. Dynamic response of a 120 mm smoothbore tank barrel during horizontal and inclined firing positions
AbstractIn this study, the dynamic interaction between a 120 mm smoothbore tank barrel modeled as an Euler-Bernoulli cantilever beam and an accelerating projectile during firing is presented. The interaction was modelled using a new FEM approach that took into account the projectile's inertia, Coriolis, and centripetal forces and the horizontal and inclined

6. A new FEM procedure for transverse and longitudinal vibration analysis of thin rectangular plates subjected to a variable velocity moving load along an arbitrary trajectory
A combined plate element is presented for the analysis of transverse and longitudinal vibrations of a thin plate which carries a load moving along an arbitrary trajectory with variable velocity. Depending on the acceleration of the point load on its trajectory on the plate surface, the combined element, which is a combination of the 24 DOF plate element and

7. Tuberculoid leprosy presenting as a “racket” lesion
Abstract The "racket" lesion is a rare presentation of tuberculoid leprosy, which consists of a thickened nerve branch emerging from a tuberculoid plaque. It results from centripetal damage to cutaneous nerves caused by granuloma formation. We describe a typical case of tuberculoid leprosy presenting as a "racket" lesion. The lesion persisted after treatment

8. Jornal Correio Paulistano - constituição e mudança do gênero anúncio de emprego (1854 a 1900) sob a perspectiva crítico-discursiva / Newspaper Correio Paulistano - Constitution and change in Job Advertisements genre (from 1854 to 1900) under a critical-discursive perspective
The aim of this thesis is to present a diachronic analysis of the speech genre job advertisements published in the newspaper Correio Paulistano from 1854 to 1900. Based on the perspective of Mikhail Bakhtin, we will emphasize their constitutive aspects and their relative stability, because speech genres are the product of a dialogic tension between two force

9. Characterization of poly (L-co-D,L Lactic Acid) and a study of polymer-tissue interaction in subcutaneous implants in wistar rats
Poly (L-co-D,L lactic acid) (PLDLA) is an important biomaterial because of its biocompatibility properties that promote cellular regeneration and growth. The aim of this study was to evaluate the polymer-tissue interaction of PLDLA implants in the dorsal subcutaneous tissue of male Wistar rats at various intervals (2, 7, 15, 30, 60 and 90 days) after implant

10. O conceito de língua/linguagem em 1984 de Orwell
Este trabalho discute o conceito de língua/linguagem em 1984 de George Orwell e relaciona esse conceito com o da linguística oficial russa das décadas de 1920/1930. Para tanto, selecionamos, especificamente, a novilíngua como corpus de pesquisa. A novilíngua consiste em um sistema linguístico elaborado pelos detentores do poder da ficção orwelliana q

11. Rate control system algorithm developed in state space for models with parameter uncertainties
Abstract researching in weightlessness above the atmosphere needs a payload to carry the experiments. To achieve the weightlessness, the payload uses a rate control system (RCS) in order to reduce the centripetal acceleration within the payload. The rate control system normally has actuators that supply a constant force when they are turned on. The developme

12. Aquisição de fonologia : a influiência do acento e o preenchimento de unidades prosódicas em dados de fala de duas crianças entre 1;0.4 e 2;1.10 de idade, em contato com o português brasileiro falado em Alagoas e Pernambuco. / Acquisition of phonology: the influience accent and segment completion of prosodic units in speech data from two children between the ages of 1;0.4 e 2;1.10 and who were exposed to Brazilian Portuguese spoken in the states of Alagoas and Pernambuco.
The study delves into the influence of accent and segment completion of prosodic units in speech data from two children between the ages of 1;0.4 and 2;1.10 and who were exposed to Brazilian Portuguese spoken in the states of Alagoas and Pernambuco. It was hypothesized that grammatical processing stems from two concurrent movements in opposing directions dur
