13. Numerical analysis of cold-formed double angles back-to-back under compression
Abstract Here-in, a numerical analysis based on the Finite Element Method (FEM) is proposed in order to investigate cold-formed steel back-to-back double angle structural behavior under compression. Considering non-linear analysis, an investigation was performed to analyze the influence of some aspects, such as the loading condition (concentric and eccentric

14. Time to task failure of the contralateral untrained limb after high load-low repetition eccentric and low load-high repetition resistance training
Abstract Aims: Cross-training is the process whereby training of one limb gives rise to enhancements in the performance of the opposite, untrained limb and may be dependent on type of muscle contractions performed. The aim of this study was to investigate whether unilateral resistance training using eccentric contraction is more effective than concentric res

15. Comparative study on morpho-anatomy of leaf, stem and root of Boerhaavia diffusa L. (Nyctaginaceae) and its adulterant plants
ABSTRACT Punarnava (Boerhaavia diffusa L.- Nyctaginaceae) is a promising drug to rejuvenate new cells in the body. It is well known in Ayurvedic medicine and locally called Tambadivasu. Superficially it is similar to other species of Boerhaavia and species of Trianthema and Sesuvium. Due to the minute morphological differences, the above plants are erroneous

16. Longer repetition duration increases muscle activation and blood lactate response in matched resistance training protocols
Abstract This study analyzed the effect of different repetition durations on electromyographic and blood lactate responses of the bench press exercise. Fifteen recreationally trained male volunteers completed two training protocols, matched for intensity (% one-repetition maximum; 1RM), number of sets, number of repetitions, and rest intervals. One of the pr

17. Research on Free Vibration Frequency Characteristics of Rotating Functionally Graded Material Truncated Conical Shells with Eccentric Functionally Graded Material Stringer and Ring Stiffeners
Abstract In this research work, an exact analytical solution for frequency characteristics of the free vibration of rotating functionally graded material (FGM) truncated conical shells reinforced by eccentric FGM stringers and rings has been investigated by the displacement function method. Material properties of shell and stiffeners are assumed to be graded

18. Clinical commentary of the evolution of the treatment for chronic painful mid-portion Achilles tendinopathy
ABSTRACTThe chronic painful Achilles tendon mid-portion was for many years, and still is in many countries, treated with intratendinous revision surgery. However, by coincidence, painful eccentric calf muscle training was tried, and it showed very good clinical results. This finding was unexpected and led to research into the pain mechanisms involved in this

19. Failure behavior modeling of slender reinforced concrete columns subjected to eccentric load
AbstractThis work presents a numerical model to simulate the failure behavior of slender reinforced concrete columns subjected to eccentric compression loads. Due to the significant influence of the lateral displacements on the loading state provided by an eccentric load, geometric nonlinearity is considered. The responses of the concrete in tension and comp

20. The effect of the inner cylinder rotation on the fluid dynamics of non-Newtonian fluids in concentric and eccentric annuli
Helical flow in an annular space occurs during oil drilling operations. The correct prediction of flow of drilling fluid in an annular space between the wellbore wall and the drill pipe is essential to determine the variation in fluid pressure within the wellbore. This paper presents experimental and CFD simulation results of the pressure drop in the flow of

21. Effects of isokinetic eccentric training on knee extensor and flexor torque and on gait of individuals with long term ACL reconstruction: A controlled clinical trial
"Efeitos do treinamento isocinético excêntrico de extensores de joelho e torque flexor na marcha de indivíduos com reconstrução do LCA: Um ensaio clínico controlado." Este estudo investigou os efeitos do treinamento isocinético excêntrico (TIE) sobre o torque extensor e flexor do joelho e parâmetros cinemáticos da marcha de indivíduos com reconstr

22. Neural and morphological adaptations of vastus lateralis and vastus medialis muscles to isokinetic eccentric training
"Adaptações neurais e morfológicas dos músculos vasto lateral e vasto medial para treinamento isocinético excêntrico." Vasto lateral (VL) e vasto medial (VM) são comumente visados em programas de condicionamento/reabilitação devido ao seu papel na estabilização patelar durante a extensão do joelho. Este estudo avaliou as adaptações neurais e mu

23. A single bout of exercise with a flexible pole induces significant cardiac autonomic responses in healthy men
OBJECTIVES: Flexible poles can provide rapid eccentric and concentric muscle contractions. Muscle vibration is associated with a "tonic vibration reflex” that is stimulated by a sequence of rapid muscle stretching, activation of the muscle spindles and stimulation of a response that is similar to the myotatic reflex. Literature studies analyzing the acute

24. Biomechanical evaluation of subcrestal dental implants with different bone anchorages
This study evaluated the biomechanical influence of apical bone anchorage on a single subcrestal dental implant using three-dimensional finite element analysis (FEA). Four different bone anchorage designs were simulated on a posterior maxillary segment using one implant with platform switching and internal Morse taper connection as follows: 2 mm subcrestal p
