1. Immediate effects of temporary bite-raising with light-cured orthodontic band cement on the electromyographic response of masticatory muscles
Abstract Objective: To assess the immediate effects of temporary bite-raising using light-cured orthodontic band cement on the superficial masseter and anterior temporalis electromyography (EMG) activity in healthy adults. Materials and Methods: Surface EMG signals were recorded bilaterally from the superficial masseter and anterior temporalis muscles of 3

2. Estudo do efeito dos parâmetros de síntese na condutividade elétrica do compósito fluoreto de polivinilideno / polianilina
ABSTRACT The electroactive polymers have been the subject of many studies in the last decade, mainly because its unique properties. They are used in composite structures, which allow its application in many fields, as for example, sensors and artificial muscles. The electrical properties of these composites are influenced by the doping state of the electroac

3. Evaluation of Meat and Egg Traits of Beijing-you Chickens Rotationally Grazing on Chicory Pasture in a Chestnut Forest
ABSTRACT Barn and cage-fed chickens have presented several problems, such as high rates of infectious disease and consequent antibiotic abuse, poorer chicken health and welfare, and often poorer meat and egg quality compared with free-range chickens. The poultry agroforestry system is becoming increasingly popular in many poultry farms nowadays. In this stud

4. Study of the Influence of the Hydration Level on the Electromechanical Behavior of Nafion Based Ionomeric Polymer-metal Composites Actuators
The ionomeric electroactive polymers-metal composites (IPMC) are materials that realize bending movements in response to an electrical stimulus and can be applied to the artificial muscles development. This paper investigated the influence of the hydration level on the electromechanical behavior of Nafion based IPMC. An experimental apparatus composed by a s

5. Análise da cinemática dos compartimentos da parede torácica nas posições supino e sentada de pacientes com esclerose lateral amiotrófica
Amyotrophic Lateral Sclerosis (ALS) is characterized by deterioration of upper and lower motor neurons. The main components, which alter the respiratory muscles are the inspiratory, expiratory, and bulbar, leading to chronic respiratory failure. One way to improve gas exchange of these individuals is by employing non-invasive ventilation (NIV). Therefore, th

6. DESENVOLVIMENTO DE ATUADORES TRIDIMENSIONAIS BASEADOS EM MÚSCULOS ARTIFICIAIS DIELÉTRICOS DE UMA OU MÚLTIPLAS CAMADAS / DEVELOPMENT OF THREE-DIMENSIONAL ACTUATORS BASED ON DIELECTRIC ARTIFICIAL MUSCLES OF ONE OR MULTIPLE LAYERS
Artificial muscles are versatile for the actuator projects, because, as well as the natural muscles, they can have small dimensions or they are grouped to obtain big dimensions. Muscle capacity to allow construction of actuators without movable parts allows great economy of energy, avoiding attritions for sliding, lessening waste, and reducing noise.Artifici

7. Comportamento eletromiografico dos musculos esternocleidomastoideos e paraespinhais cervicais em pacientes laringectomizados totais / Electromyographic behavior of the sternocleidomastoid and cervical paraspinal muscles in patients with total laryngectomy
The most common head and neck cancer types are the skin, mouth and larynx cancers, occurring mainly in males, older than fifty years old. The head and neck cancer treatment, employing surgery, chemical therapy, and radiotherapy, presents sequels that affect basic functions as breathing, deglutition, phonation and the mobility of the cervical segment of verte

8. Occlusal force, masticatory cycles and mandibular flexure of subjects with different facial types / Força de mordida, ciclos mastigatorios e deflexão mandibular em individuos com diferentes tipos faciais
Bite force can influence the development of the masticatory function and consequently the rehabilitation therapeutics. The high variability of this muscular function indicator can be associated to intrinsic aspects of the stomatognathic system such as the vertical facial morphology. However, the influence of this morphology on the maximum bite force and func

9. CARACTERIZAÇÃO DE ATUADORES BASEADOS EM MÚSCULOS ARTIFICIAIS POLIMÉRICOS POR EFEITO CAPACITIVO / CHARACTERIZATION OF ACTUATORS BASED ON POLYMERIC ARTIFICIAL MUSCLES WITH CAPACITIVE EFFECT
It is well known the needs of finding new technologies for robotic systems actuations, with the same efficiency of the natural muscles. The common actuators have better agility and force when compared to natural muscles, but the dimensions and weight are bigger and for that the demand of energy necessary for the actuation is higher. Smaller and cheaper robot

10. Uma contribuição ao desenvolvimento de manipuladores antropomorficos com enfase na utilização de musculos artificiais / A contribution to the development of anthropomorphic manipulators with emphasis in the use of artificial muscles
Este trabalho visou o estudo de manipuladores à semelhança do membro superior humano. Após o estudo do membro superior humano e dos robôs antropomórficos disponíveis tanto na industria quanto no meio acadêmico, utilizaram-se teorias de modelagem geométrica, cinemática direta e cinemática inversa para realizar o modelo de um manipulador robótico an

11. Evaluation of maximal inspiratory pressure (Pi Max), Airway Occlusion Tracheal Pressure (P 01) and its ratio in weaning outcome of mechanical ventilation / Avaliação da força muscular inspiratória (Pi Max), da atividade do centro respiratório (P 0.1) e da relação da atividade do centro respiratório/força muscular inspiratória (P 0.1 / Pi Max) sobre o desmame da ventilação mecânica
Introduction: We hypothesized that maximal inspiratory pressure (Pi Max), airway tracheal occlusion pressure (P 0.1) and its ratio (P 0.1/Pi Max) can be used to predict weaning outcome in a mixed ICU mechanically ventilated patients. Methods: Pi Max, P 0.1 and P 0.1 / Pi Max ratio were measured in seventy consecutive intubated or tracheostomized, mechanicall

12. Reproductive parameters of captive male partridge (Rhynchotus rufescens): artificial insemination versus natural service / Parâmetros reprodutivos de perdizes machos (Rhynchotus rufescens) criadas em cativeiro: comparação entre os índices reprodutivos de animais acasalados e inseminados
The partridge (Rhynchotus rufescens) belongs to the tinamidae family and possesses breast muscles which are quite appreciated in high cuisine However, there is an insignificant large scale production, which could be improved using the artificial insemination (AI). The present experiment aimed to standardize semen collection and the hipoosmotic swelling test
