1. Is It Possible to Classify Topsoil Texture Using a Sensor Located 800 km Away from the Surface?
ABSTRACT It is often difficult for pedologists to “see” topsoils indicating differences in properties such as soil particle size. Satellite images are important for obtaining quick information for large areas. However, mapping extensive areas of bare soil using a single image is difficult since most areas are usually covered by vegetation. Thus, the aim

2. Project, development and testing In vitro of new model pump for cardiopulmonary bypass : spiral pump / Projeto, desenvolvimento e ensaios "In Vitro" de novo modelo de bomba de sangue para circulação extracorpórea : bomba espiral
A model of blood pump has been developed, the Spiral Pump. This pump has an internal rotor, a conically shaped fuse, containing threads with double entrance on its surface. This rotor is supported by two bearings assembled at a stainless steel shaft, fixed to the housing´s base. The rotation of the conical fuse is generated by magnetic coupling to a motor,

3. Experimental research of the random fuse model / Estudo experimental do modelo aleatório de fusíveis
O objetivo deste trabalho é verificar, através de um estudo experimental do Modelo Aleatório de Fusíveis, como a orientação e a desordem da rede de fusíveis influenciam o processo de fratura da rede. Para a efetivação dos experimentos foi criado um circuito de tamanho L x L, com as ligações entre os fusíveis orientadas à 45 da direção de aplic

4. Redes de fusíveis livres de escala para simulação de fratura em materiais compósitos
The study of fracture of composite materials has a distinguished relevance due the broad and ever increasing use of multiphase materials to attend specific needs and/or combine cost and functionality. Theoretical approach to the issue include simplified models, yet many times mathematically unfeasible, providing information of little practical use. As an alt

5. Otimização de índices de confiabilidade em redes de distribuição de energia elétrica
An eletric utility must install protection (reclosers and fuses) and sectionalizing (switches) devices in key points of its distribution network to serve its customers with a reliable power supply. Utility boards or similar commissions define measures (reliability indices) to quantify and analize the eletric utility services. The problem addressed in this wo

6. Estudo da proteína de choque térmico GRP78 para o desenvolvimento de um sistema de receptor-ligante para o câncer de próstata / Use of the heat-shock protein GRP78 for the development of a receptor-ligand system in prostate cancer
Introduction: Despite the advances in diagnosis and treatment, advanced prostate cancer remains a lethal condition. Improved methods of therapy are needed to reduce the morbidity and mortality rates associated with this disease. The Glucose-regulated protein-78 (GRP78), a stress-responsive heat-shock protein involved in antigen presentation, was recently des

7. Influencia da armazenagem em agua na resistencia a flexão biaxial de porcelana unida a materiais resinosos para fixação
The purpose of this study was to evaluate the influence of water storage on the tensile strength of feldspathic porcelain associated to resin cements. One hundred twenty porcelain discs (21 mm in diameter x 2 mm thick) were fabricated in two different layers. The first one was done of medium fuse porcelain (Duceram - Degussa), followed by the application of

8. More cold fusion in metals: corrected calculations and other considerations.
A simple model of a metal containing deuterons is considered. The example of palladium is treated in detail. In contrast to a previous calculation, it is shown that the effect of screening of Coulomb fields by conduction electrons is sufficient to allow a deuteron pair to fuse at a rate of 10(-18) sec-1, five powers of 10 larger than some experimental result

9. Glucocorticoid Inhibition of RNA Synthesis Responsible for Cleft Palate in Mice: A Model*
A study was undertaken to elucidate the molecular mechanisms by which glucocorticoids induce cleft palate in mice. It was hypothesized that a compound such as triamcinolone acetonide inhibits mRNA synthesis; that this results later in depressed protein synthesis; and that the latter is ultimately responsible for slowed palate formation and cleft palate. Supp

10. The Role of the Tethering Proteins p115 and GM130 in Transport through the Golgi Apparatus In Vivo
Biochemical data have shown that COPI-coated vesicles are tethered to Golgi membranes by a complex of at least three proteins: p115, giantin, and GM130. p115 binds to giantin on the vesicles and to GM130 on the membrane. We now examine the function of this tethering complex in vivo. Microinjection of an N-terminal peptide of GM130 or overexpression of GM130

11. Cold fusion in metals
A simple model of a metal containing deuterons is considered. The example of palladium is treated in detail. It is shown that the effect of screening of Coulomb fields by conduction electrons is sufficient to allow deuteron pairs to fuse at rates of 10-30 sec-1, seven orders of magnitude smaller than those reported by Jones et al. [Jones, S. E., Palmer, E. P

12. Fusion of renal epithelial cells: a model for studying cellular mechanisms of ion transport.
The investigation of epithelial ion transport at the cellular level by means of electrophysiological techniques is hampered by the small size of epithelial cells. Moreover, interpretation of experiments is complex due to poorly defined and highly variable paracellular leaks (shunt pathways). In search of a new experimental approach we developed a technique t
