Relationship of Pulsation Rate, Pulsation Ratio, and Vacuum Decrease Time to Milking Performance

Time Domain Approach to Gas Pulsation Modeling

Evaluation of an experimental milking pulsation system for effects on milking and udder health.

This study was to test whether cows milked by an experimental pulsation method differed from cows milked with conventional pulsation milking in somatic cell count (SCC), intramammary infections (IMI) defined by milk bacteriological culture results, teat end condition, or milk flow rate. The study design was a 1-yr trial with a completely randomized block crossover. Holstein cows were blocked in...

Decrease of venous return caused by right atrial pulsation.

• For almost as long as the problem of venous return has been studied, two different factors have been claimed to be important in determining venous return to the heart." These are: (1) the force of the systemic arterial pressure pushing blood through the systemic circulation toward the heart, and (2) factors on the venous side of the heart that affect venous return, including rhythmic suction ...

LINEAR PULSATION CHARACTERISTICS OF MIRA VARIABLE STARS

The linear adiabatic pulsation-periods of Mira variable stars have been derived. Approximately 2701[1]models were calculated for M = 0.7 MΘ to 2 MΘ stars with radii from 180 RΘ to 340 RΘ and luminosities from 2800 LΘ to 10,000 LΘ. The chemical composition of all models is (X,Z) = (0.7,0.02). From the result of this study, linear relations on Luminosity-Period-Mass relationship and luminosity-pe...

Relationship of Spontaneous Retinal Vein Pulsation with Ocular Circulatory Cycle

PURPOSE To determine the timing of spontaneous venous pulsation (SVP) relative to the ocular circulatory cycle by using the movie tool of confocal scanning laser ophthalmoloscope. METHODS A video recording of the fundus was obtained using a confocal scanning laser ophthalmoscope (Spectralis HRA, Heidelberg Engineering, Heidelberg, Germany) at 8 frames/s in 47 eyes (15 glaucoma patients and 32...
