Variabilitas Spasial Dan Temporal Suhu Permukaan Laut Dan Klorofil-a Di Perairan Selat Malaka Melalui Citra Satelit Aqua Modis

This research was meant to find out variability temperature and klorofil-a the surfaceeither of sea in spatial or temporal in Malacca strait waters in the Eastern (June - August)during the cycle of recording (2009 - 2012). Methods used is desk analysis is analyzed dataobtained without doing validation and verification in the field. The data in described based ontheories. A pattern of distribution spl very closely relation to patterns of wind that blows in anarea. To scatter spl in malacca strait waters also affected by oscillations climatology. Saji, etal ( 2003 ) in Lubis ( 2012 ) presented the sea surface temperatures in the tropics varying inspatial and temporal. The maximum value temperature the average sea level in malacca straitwaters in the eastern 2009-2012 year reaching 35 oc network. Distribution klorofil-a inmalacca strait waters in the eastern 2009-2012 year average value maximum velocity reached55,40 mg / m3

Patterned conductive nanostructures from reversible self-assembly of 1D coordination polymer

In this study, the outstanding ability of the coordination polymer [Pt-2(nBuCS(2))(4)I](n) (nBu = n-butyl) (1) to reversibly self-organize from solution was demonstrated. This feature allowed us to generate highly electrical conductive structures located upon demand on technologically relevant surfaces, by easy-to-handle and low cost micromolding in capillaries (MIMIC) and lithographically controlled wetting (LCW). Electrical characterization reveals a near Ohmic behaviour and a high stability of the stripes (in air). Electrodes produced by the MIMIC technique from a solution of compound 1 demonstrated that this material can be efficiently used as electrodes for organic field-effect transistors (OFETs)

Physiological Responses of Callus from Gerbera jamesonii Bolus ex. Hook f. to Gamma Irradiation

In the present study, in vitro mutagenesis techniques were applied to investigate the effects of gamma irradiation at 0, 10, 20, 30, 40, 50 and 60 Gy on physiological changes in callus of Gerbera jamesonii Bolus ex. Hook f. Biochemical changes in chlorophyll and soluble protein content of pre- and post- irradiated Gerbera callus were studied. Non-irradiated callus demonstrated the highest amount of chlorophyll content as compared to callus irradiated at 10, 20, 30, 40, 50 and 60 Gy. In addition, the amount of chlorophyll b was relatively higher than chlorophyll a in both the irradiated and non-irradiated callus, except for callus irradiated at 10 Gy. Biochemical differentiation based on total soluble protein content revealed gradual reduction after day 9 of exposure to gamma irradiation. Reduction of soluble protein content was observed in all the treatments as the increase of incubation period
