Charles Cobb and Paul Douglas in 1928 used data from the US manufacturing sector for 1899-1922 to introduce what is known today as Cobb-Douglas production function that has been widely economic theory decades. We employ R programming language fit formulas parameters of generated by authors recently via bi-Hamiltonian approach same set utilized Douglas. conclude output elasticities total factor ...

Standard growth theory implies that steady-state growth in the presence of exponential declines in the prices of computers and other capital equipment requires a Cobb-Douglas production function. Conventional wisdom holds that capital shares are relatively constant, so that the Cobb-Douglas approach might be a good way to model growth. Unfortunately, this conventional wisdom is misguided. Capit...

BACKGROUND Conservative treatment in the Scheuermann's kyphosis obtain, during skeletal growth, remodelling of the deformed vertebras. In a previous paper on Scheuermann's kyphosis, we have studied the geometry variations of all vertebrae included in the curve, before and after the treatment. The purpose of this study was to confirm the effectiveness of conservative treatment in Scheuermann's k...

Materials and methods Prospective study 32 patients surgery AIS from 2003 to 2006. 3 males-29 females. Mean age 15.9 years. BMI and Cobb angle was measured before surgery. After we measure Cobb, the physical alteration of perception by BSQ14, the postoperative satisfaction with a questionnaire of 8 questions and the SRS-22 [2].Patients were grouped according to BMI, BMI <18 (group 1) and> 18 (g...

Results Average Cobb angle before treatment was 36.5°, which was reduced in the trial brace to 23.2°: correction rate was 36% (34% for T, 69% for TL, and 31% for D curve). Of 54 patients, 20 met the inclusion criteria of the SRS brace study (Risser 0-2, Cobb angle 25-40° ) and six of them reached skeletal maturity during the treatment period. Three of them (50%) progressed more than 6°; however...

Materials and methods Forth three scoliosis patients (12 males, 31 females) were enrolled in this study. Mean age was 10.3 years (range 615). Mean Radiographic Cobb angle before treatment was 37.2°. All the patients were investigated before bracing with "Spinal Mouse" in convex side bending position. After three months of bracing we assessed the radiographic Cobb angle and defined a correlation...

Background The EOS is a low-dose digital stereoradiography system that can produce highly reproducible spine measurements. The Milwaukee Topographic System (MTS) has reliably detected the 3-dimensional (3D) back surface contour changes. The correlation between Cobb angles and the MTS analog to Cobb angles in both the sagittal and coronal planes have been studied, but data are limited for compar...

Szent-Gy6rgi. The nerve is described as an electro-chemical generator, although it is admitted that the events at the synapses are pirobably "not purely electrical." The theory envisages the electrotonic current as the "master tool of nervous integration." This may be true, but probably will not be proven for many years. In the meanwhile it is confusing to use the vocabulary of the electrical p...
