1. Low-cost Colonoscopic Simulator and Colonoscope to Train Basic Skills in Colonoscopy during Undergraduate Studies
Abstract Objective To develop a low-cost simulator model and a colonoscope with materials that are easily accessible to offer training on colonoscopy skills during undergraduate studies. Since this is the procedure of choice for colorectal cancer screening, the general practitioner must be able to recognize its main indications, preparation, and complicatio

2. PRIMARY SPHINCTEROPLASTY COMPARING TWO DIFFERENT STITCHES IN ANAL FISTULA TREATMENT: EXPERIMENTAL STUDY IN RATS
RESUMO Racional: Fístula anal tem por definição a comunicação entre o reto ou canal anal com a região perineal, trajeto este que pode encontrar-se epitelizado e tem origem criptoglandular em 90% dos casos. Há grande número de técnicas para o tratamento das fístulas transesfincterianas com sucesso de 20-85%, incluindo-se a esfincteroplastia primá

4. Shape change analysis of tensegrity models
Abstract This paper presents a computational strategy for shape change of tensegrity models to achieve the prescribed target coordinates of a set of monitored nodes via forced elongation of cables. Mathematical formulation for incremental equilibrium equations of a tensegrity model during the shape change analysis is derived and presented. An optimization ap

6. Strength analysis of composite cables
Abstract Carbon Fiber Reinforced Polymer (CFRP) cables, due to their outstanding performance in terms of specific stiffness and strength, are usually found in civil construction applications and, more recently, in the Oil & Gas sector. However, experimental data and theoretical solutions for these cables are very limited. On the contrary, several theoretica

7. Design and Analysis of a Novel Spacecraft for Mitigating Global Warming
ABSTRACT: A device called Huge Space Shield (HSS) has been put forward for mitigating global warming. This is a space tethers system, which use cables to connect a shielding surface and a mechanism control. In this study, orbital analysis was carried out to choose the best orbit for getting the best effect. Simulation studies were employed to understand the

8. Circuit models of Lossy Coaxial Shielded cables to Analyze Radiated and Conducted Susceptibilities with unmatched line loads
Abstract This paper presents a circuit models to analyze the variation effects of incident plane wave on shielded coaxial cables, using Branin's method, which is called the method of characteristics. The model can be directly used for the time-domain and frequency-domain analyses and for all arbitrarily loaded. This makes it easy to insert in circuit simulat

9. Mechanics of Cable-Suspended Beams
Abstract The cable-suspended bridges differ from the elastic structures because of the inherent nonlinearity of the suspension cables. The primary focus of the available theories is to investigate the effect of nonlinearities associated with the distributed self-weight of the cable and its finite elastic displacements. The main point of departure of this pap

10. Experimental evaluation of the wind effects on an operating power transmission tower
Abstract Static and dynamic effects on power transmission towers can be evaluated by methodologies available in codes, which suggest the use of linear static analysis. By using numerical simulations, it is possible to observe the strong influence of the geometric nonlinear behavior of transmission cables. Dynamic effects also strongly influence this behavior

11. Parametric Study of Stay Cables of a Bridge Under Simulated Spatially Correlated Turbulent Wind
Abstract The main objective of this work is to carry out a parametric study of stay cables of a bridge under simulated spatially correlated buffeting forces. This vibration mechanism is simulated with an Autoregressive and Moving Average (ARMA) model, and applied to mathematical models of the stay cables of the tallest cable-stayed bridge in Mexico. The use

12. Theory of Weightless Sagging Elasto-Flexible Cables
Abstract In this Paper, a theory of single sagging planer weightless elasto-flexible cables is proposed. In reference to the instantaneous natural state, hypoelastic rate- type constitutive equations and third-order nonlinear differential equations of planer motion for massless cables with nodal masses are derived. New concepts like configurational complemen
