Thoracic outlet syndrome can result from injury, disease, or a congenital problem, such as an abnormal first rib. It is more common in women than in men, and poor posture and obesity can aggravate the condition. Psychological changes are often seen in patients with thoracic outlet syndrome.
Excess detergent can also be removed from a proteinsolution with Bio-Beads Â® SM-2 adsorbent.Alternatively, the Bio-Rad DC(detergent compatible) Protein Assaycan be used. The DCProtein Assay is a modified Lowry assay whichworks in the presence of 1% ionic or nonionic detergent. This two-step method is ready to evaluate in just 15 minutes, and each kit willassay up to 500 samples with the standard method, or 10,000 sampleswith the microplate method.3.
Classifications of DC machines : (DC Motors and DC Generators) Each DC machine can act as a generator or a motor. Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad categories of dc machines; (i) Separately excited and (ii) Self-excited. Separately excited: In separately excited dc machines, the field winding is supplied from a separate power source. That means the field winding is electrically separated from the armature circuit.
