Gauge fields with respect to d=(3+1)d=(3+1) in the Kaluza-Klein theories and in the spin-charge-family theory

It is shown that in the spin-charge-family theory, as well as in all the Kaluza-Klein like theories, vielbeins and spin connections manifest in $d=(3+1)$ space equivalent vector gauge fields, when space with $d\ge5$ manifests large enough symmetry. The authors demonstrate this equivalence in spaces with the symmetry of the metric tensor in the space out of $d=(3+1)$ - $g^{\sigma \tau} = \eta^{\sigma \tau} \,f^{2}$ - for any scalar function $f$ of the coordinates $x^{\sigma}$, where $x^{\sigma}$ denotes coordinates of space out of $d=(3+1)$. Also the connection between vielbeins and scalar gauge fields in $d=(3+1)$ (offering the explanation for the Higgs's scalar) is discussed.Comment: 9 pages, EPJC macros, revised version to be published at EPJ

Uji Pemeliharaan Ikan Pelangi Irian (Melanotaenia Boesemani) Di Dalam Sistem Resirkulasi [Study of Raibow Fish Culture (Melanotaenia Boesemani) in Recirculation System]

Irian rainbow fish (Melnnotnenia boesemani) is Papua ornamental fish. The culture problem of the fish has been low growth and survival rate, so that needed improvement to their culture method. Recirculation system can be an alternative model for the culture. The aim of research is to recognize growth characteristic of rainbow fish which be cultured on raceway model recirculation system. Oval shape pond used (300 x 120 cm²) by four partitioned, with water height 23.5 cm. Water flow moved by aerator and gravel was used for filter. The fish was stocked about 950 fishes, with length and weight average was 15.6 and 0.18 gram, respectively. Tubificidae was used for feed, in enough quantity. Research duration was two months, except fish observation until three months as support data. Sample of fish (5% of population) was measured their length-weight, and growth parameters was analyzed. Several water quality parameters measured, namely temperature, pH, dissolved oxygen, nitrite and ammonia content, and Chemical Oxygen Demand. Water quality condition on suitable during observation. Survival rate of fish reached 79%, growth rate was low (a =0.70% ), and indicated decrease of length growth on third month. Feed efficiency (e) was very low (4.15%) with food conversion ratio 13.4. Length-weight relationship indicated high linier relation (R>0.86) except on beginning observation (R = 0.55). Fish length groups indicated wider distribution parallel to increase of age

"An effective two dimensionality" cases bring a new hope to the Kaluza-Klein[like] theories

One step towards realistic Kaluza-Klein[like] theories and a loop hole through the Witten's "no-go theorem" is presented for cases which we call an effective two dimensionality cases: In $d=2$ the equations of motion following from the action with the linear curvature leave spin connections and zweibeins undetermined. We present the case of a spinor in $d=(1+5)$ compactified on a formally infinite disc with the zweibein which makes a disc curved on an almost $S^2$ and with the spin connection field which allows on such a sphere only one massless normalizable spinor state of a particular charge, which couples the spinor chirally to the corresponding Kaluza-Klein gauge field. We assume no external gauge fields. The masslessness of a spinor is achieved by the choice of a spin connection field (which breaks parity), the zweibein and the normalizability condition for spinor states, which guarantee a discrete spectrum forming the complete basis. We discuss the meaning of the hole, which manifests the noncompactness of the space.Comment: 26 pages, 1 figure, an addition which helps to clarify the assumptions and their consequences (the discreteness of spectrum, the massless solution of one handedness,..

Zooplankton Community in Lamalera Sea and Sawu Sea, East Nusa Tenggara

Zooplankton community was studied in Lamalera Sea and Sawu Sea during DIKTI-P2O LIPI Expedition from 19 – 30 July 2011. Besides being a potential fishing ground, the Lamalera sea and Sawu Sea have been a migration path for Cetacean (large marine mammals), particularly during the southeast monsoon season. The purposes of this study were to investigate community structure, abundance, and spatial distribution of zooplankton in the Lamalera Sea and the Sawu Sea. Plankton samples were collected from 23 stations, by NORPAC 300 µm-net that was vertically hauled from maximum 200 meter depth up to the surface water. The result showed that there were 45 taxa of zooplankton, which was dominated by copepods . The abundance of the zooplankton between 491 - 4537 individu/m3. Average diversity index and evenness values were 1.59 ± 0.21 and 0.50 ± 0.04, respectively. In this area, Creel has been found in all research stations but the abundance was small. Species composition was relatively the same between sampling stations suggesting that there was no different in composition between north and south parts, which virtually comprise of different water masses. It showed that spatial distribution of zooplankton was relatively wide-reaching
