13. In vitro evaluation of the precision of working casts for implant-supported restoration with multiple abutments
OBJECTIVE: The purpose of this study was to compare the accuracy of two working cast fabrication techniques using strain-gauge analysis. METHODS: Two working cast fabrication methods were evaluated. Based on a master model, 20 working casts were fabricated by means of an indirect impression technique using polyether after splinting the square transfer coping

14. Food mechanics: a new device for testing fruits and vegetables
The new mechanical device developed is capable of performing compression tests but also bending, torsion and tensile tests. Its measurement system has the following components: a load cell (0 to 9800 N), a strain gauge signal conditioning board, a plug-in general purpose data acquisition board, and a displacement sensor (0 to 29.7 mm). These components are c

15. Influência da extensão e tipo de retentor intra-radicular na deformacão e resistência à fratura de dentes tratados endodonticamente
Studies concerning the effects of different post systems insertion depth on the strain and fracture resistance of endodontically treated teeth remain controversial. The purpose of this study was to investigate in vitro the effects of different post systems and depth of post insertion on the strain and fracture resistance of endodontically treated bovine inci

16. Shoulder effort in paraplegic locomotion: kinetics and EMG assessment / Esforço do ombro na locomoção de pacientes paraplégicos: avaliação cinética e eletromiográfica
Spinal Cord Injured subjects often refer pain in their shoulders, due to the increased demand of the upper limbs. These subjects usually go through different rehabilitation strategies. Therefore, it becomes rather important to assess those methods in order to avoid further injuries to the patients. The goal of this work was to evaluate the shoulder effort an

17. Timing as a prominent factor of the Jendrassik manoeuvre on the H reflex.
The influence of the Jendrassik manoeuvre on the myotatic reflex was analysed using a strain gauge as an indicator of the upper extremity movement and the H reflex of the soleus muscle as the test reflex. The most prominent factor responsible for the enhancement was not the speed or the strength of the manoeuvre but the timing from the instruction.

18. Diagnostic tests in Raynaud's phenomena in workers exposed to vibration: a comparative study.
Four objective tests to evaluate Raynaud's phenomena (RP) in workers exposed to handarm vibrations were applied on 23 exposed men with RP (vibration induced white finger 18, primary Raynaud's phenomenon 5), 56 exposed men without RP, and 15 male controls. Finger systolic blood pressure was measured by a cuff and strain gauge technique after combined body coo

19. The possible relation between mastication and parotid secretion in the rabbit.
Salivary flow has been recorded from conscious rabbits during 1 min periods whilst continuously chewing standard laboratory dry pellets or pieces of carrot and, in some animals, a mash of pellets with water. Flow was measured using contact drop recorders or a continuous flow recorder via Polythene tubes permanently inserted into one or both parotid ducts. La

20. Vasoconstrictor response to cold in forestry workers: a prospective study.
In a five year prospective study of the vasoconstrictor response to cold 37 forestry workers were investigated in 1978 and again in 1983. The subjects were classified into three groups: group A (n = 13): no subjective finger symptoms in 1978 and continued sawing until 1983; group B (n = 12): no symptoms in 1978 and stopped sawing before 1983; group C (n = 12

21. Relation between serum uric acid and lower limb blood flow in patients with chronic heart failure.
OBJECTIVE: To determine whether lower limb blood flow is related to serum uric acid concentrations in patients with chronic heart failure, taking into account the hyperuricaemic effects of diuretic treatment and insulin resistance. DESIGN: Lower limb blood flow was measured at rest and after maximum exercise followed by a five minute period of ischaemia (max
