A method for monitoring the progress of fat loss in a patient during a weight loss program which comprises, contacting a body fluid sample from said patient with a solid test strip to provide a color indication of the presence in said body fluid of -hydroxybutyrate, optionally together with acetoacetate andor acetone. A housing recess which houses the washer is formed on at least one face of the faces of adjacent oscillating gears facing each other. Finally, another etching process is performed to etch through the hard-mask layer and the dielectric layer and form the damascene structure in the dielectric layer, wherein this etching process utilizes the mixed gas having chlorine, such as O2Cl2. Each transmitter is associated with an auxiliary receiver and each receiver is associated with an auxiliary transmitter in order to develop a sensor arrangement with increased security and reliability. The partitioning mechanism associates a second partition key to every DLID in the second subnet for enabling communication between the second group of endnodes over the communication fabric. An embodiment of the invention provides an RJ-45 receptacle as the peripheral device connector of an SFP transceiver.
