“…where ,u w: is the force constant. One sees that the contribution to the Hamiltonian due t o the motion in the z-direction is completely decoupled from that Hzt, coming from the motion in the xy-plane [12]. We shall concentrate ourselves on the behavior of the system in the xy-plane only.…”

The energy spectrum of Frohlich polarons in a magnetic field is investigated theoretically. The constants of the motion of the system are studied and a "Feynman model" serves as B guide in this study. A crucial difference between the energy spectra of polarons and rigid particles is predicted a t rather strong coupling strengths or large magnetic fields. It is due to the internal structure of the polaron system. When the electron-LO-phonon coupling constant becomes large enough to allow internal excitations, a resonance may appear in the one-phonon continuum. This resonance is split by Zeeman effect a t small field values and the components of the multiplet tend asymptotically to the Landau levels with increasing field strengths. The stability of one component a t least is enhanced by the magnetic field, so that magnetic fields could be used to reveal internal excitations of polarons, in cyclotron resonance or magneto-optical absorption experiments. Recent experimental results on magneto-absorption by excitons are discussed in the light of the present work. Es wird das Energiespektrum

“…Increasing urban population has influenced the high demand for clean water consumption. It affects not only the increase in water demand but also the quality and quantity of water sources in urban areas (1). Rainwater has become an alternative for water scarcity problem in which pure and accessible water can harvest through rainwater harvesting (RWH) system (2).…”

This study aimed to investigate the quality of the rooftop rainwater harvesting (RRWH) and to treat it for clean water supply alternative of Graha Rektorat building at State University of Malang, Indonesia. Different combinations of zeolite and activated carbon were used as filter media to treat the RRWH. Several parameters have tested to investigate the quality of RRWH based on Permenkes RI No. 416 / MENKES / PER / IX / 1990. Most of the quality of the RRWH met clean water and drinking water standard. However, there were three parameters have to be reduced and required further treatment. The results showed T4 reduced TDS and coliform bacteria by 37% and 36%, while T5 eliminated organic substances (KMnO4) for 35%.
