UNISON

Both PSI and PSII are necessary for photosynthesis, but the systems do not operate in the implied temporal sequence. There is also considerable pooling of electrons in intermediates between the two photosystems, and the indicated photoacts seldom occur in unison. The terms PSI and PSII have come to represent two distinct, but interacting reaction centers in photosynthetic membranes (36,37) the two centers are considered in combination with the proteins and electron-transfer processes specific to the separate centers. 

One of the remarkable features of the heart, which is about the size of a fist, is that the pumping action or contractions (- 70 times/min) of atria and ventricles are simultaneous. Deoxygenated blood is pumped out to the lungs from one side of the heart at the same time oxygenated blood is pumped out from the other side to the aorta and onward through the body. The entire process of blood flow between the atria, ventricles, and the principal vessels is in unison, controlled in part by four one-way valves. The atrioventricular valves, tricuspid on the right and mitral on the left, prevent blood from flowing... 

Einklang, m. harmony, unison, accord, einkleiden, v.t. clothe, dress coat, einklemmen, v.t. clamp pinch, nip jam. einkochen, v.t. boil down, evaporate. — ,i. thicken by boiling. 

The splitting and recombination of the beam is accomplished by means of two rotating sector mirrors which are geared to the same electric motor so that they work in unison (Fig. 17.12). The microprocessor which is used to operate such an instrument will automatically correct for the dark current of the photocell, i.e. the small current which passes even when the cell is not exposed to radiation. 

While a plastic usually exhibits not one but many relaxation times, each relaxation time is affected by the temperature in exactly the same manner as another. That is the whole relaxation spectrum shifts in unison along the logarithmic no longer applicable in these materials, because the crystalline morphology changes with the temperature. 

Then there was a kid who crouched down to watch me walking through a store with my respirator on, and called to his friend to take a look. They turned to each other and said in unison, Cool ... 

The occurrence of abnormal gait is evaluated. The most frequent impairments are waddling (W), hunched gait (H), or ataxia (A, the inability of all the muscles to act in unison). Record the extent of any impairment on a scale of 1 (slight) to 5 (marked). 

As the dark veil is removed, you hear a rich contralto chanting, IAO. Then, as the scarlet veil falls away, a pure soprano voice sings, IAO, and finally, the white veil wisps away with the whispered word, IAO. Then the three in unison Behold thy kingdom You turn to the prow to see, rising above the waves, the green hills of Logres, and in the distance, set among their emerald slopes, a white Sun shines above a walled tower. 

How she longs for the peace and quiet of the old home and the comforting touch of Reverend Mother s kind arms about her What is it that the nuns are singing The Magnificat. She listens in silence for a few moments, then, a strange smile curving her lips, she recites in unison with the choir ... 

It is quite evident that the infrared output from all these different sources invariably varies in intensity over a definite frequency range, therefore, a compensating variable slit is usually programmed to operate in unison with the scanning over the individual frequencies. 

Nothing much happened for another couple of weeks, and then on another windy day, with a hint of snow, the headache struck again, fairly rapid in onset, blinding, disabling. Hoping it would go away, she stuck it out this time. But when she mentioned it to her two workmates some 10 feet on each side of her, they exclaimed, almost in unison That s strange I ve got a headache too ... 

In general, microorganisms on/in solid phases can be viewed as a vast biological entity whose parts live in unison, with diverse capabilities for the degradation of all natural organics and many xenobiotics. The major characteristics and differences of bacteria, actinomycetes, and fungi are compared in Table 1. 

The story of matter can be read in the evolutionary models fashioned by physicists, astronomers and mathematicians working in unison. Models of stars allow us to determine their mass and their age on the basis of their colour and brightness. But these paper stars, for all their equations, must forever be confronted with real ones. 

The sounds suddenly die, replaced by two deep voices, speaking in unison. Greetings, travelers. Welcome to our world. Balls of light and little rainbow arcs come from their eyes. 

We, however, are interested in the extremely non-Markovian timescales, much shorter than on which all bath modes excitations oscillate in unison and the... 

The bath response function is usually associated with a characteristic correlation or memory time, t, which separates the non-Markovian (t t ) and the Markovian (t t ) temporal regimes, for example, 0(t) a Within the bath memory time, the bath modes oscillate coherently and in unison, and maintain memory of their interaction with the system, whereas after the correlation time has passed, the modes lose their coherent oscillations and forget their prior interactions [94].
