In order to construct a sample of ultra-luminous infrared galaxies (ULIRGs, with infrared luminosity, \(L_{\rm IR} > 10^{12}\) L\(_{\odot}\)) at 0.5 < z < 1, we are conducting an optical follow-up ...program for bright 90-\(\mu\)m FIR sources with a faint optical (i < 20) counterpart selected in the AKARI Far-Infrared Surveyor (FIS) Bright Source catalog (Ver.2). AKARI-FIS-V2 J0916248+073034, identified as a ULIRG at z = 0.49 in the spectroscopic follow-up observation, indicates signatures of an extremely strong outflow in its emission line profiles. Its OIII 5007\AA\ emission line shows FWHM of 1830 km s\(^{-1}\) and velocity shift of -770 km s\(^{-1}\) in relative to the stellar absorption lines. Furthermore, low-ionization OII 3726\AA\ 3729\AA\ doublet also shows large FWHM of 910 km s\(^{-1}\) and velocity shift of -380 km s\(^{-1}\). After the removal of an unresolved nuclear component, the long-slit spectroscopy 2D image possibly shows that the outflow extends to radius of 4 kpc. The mass outflow and energy ejection rates are estimated to be 500 M\(_{\odot}\) yr\(^{-1}\) and \(4\times10^{44}\) erg s\(^{-1}\), respectively, which imply that the outflow is among the most powerful ones observed in ULIRGs and QSOs at 0.3 < z < 1.6. The co-existence of the strong outflow and intense star formation (star formation rate of 990 M\(_{\odot}\) yr\(^{-1}\)) indicates that the feedback of the strong outflow has not severely affect the star-forming region of the galaxy.
A theory of ultra-fast pump-probe experiments proposed by us earlier F.H.M. Faisal et al., Phys. Rev. Lett. 98, 143001 (2007) and F.H.M. Faisal and A. Abdurrouf, Phys. Rev. Lett. 100, 123005 (2008) ...is developed here fully and applied to investigate the phenomena of dynamic alignment and high harmonic generation (HHG) from coherently rotating linear molecules. The theory provides essentially analytical results for the signals that allow us to investigate the simultaneous dependence of the HHG signals on the two externally available control parameters, namely, the relative angle between the polarizations, and the delay-time between the two pulses. It is applied to investigate the characteristics of high harmonic emission from nitrogen and oxygen molecules that have been observed experimentally in a number of laboratories. The results obtained both in the time-domain and in the frequency-domain are compared with the observed characteristics as well as directly with the data and are found to agree remarkably well. In addition we have predicted the existence of a "magic" polarization angle at which all modulations of the harmonic emission from nitrogen molecule changes to a steady emission at the harmonic frequency. Among other things we have also shown a correlation between the existence of the "magic" or critical polarization angles and the symmetry of the active molecular orbitals, that is deemed to be useful in connection with the "inverse problem" of molecular imaging from the HHG data.
Recent reports on intense-field pump-probe experiments for high harmonic generation from coherently rotating linear molecules, have revealed remarkable characteristic effects of the simultaneous ...variation of the polarization geometry and the time delay on the high harmonic signals. We analyze the effects and give a unified theoretical account of the experimental observations

The modified technology of fish drying in Madura has been made. The drying system consists of some locally material such as: skin coconut, hardplex, heat resistant plastic, glass and wood. The system ...dimension is 1,5m x 2,4m x 1,88 m and has capacity between 100 - 150 kg of fish. The dryer has drying rate to be than that of samples dried on open air drying around 3 times faster. So the drying technology showed that, this dryer was sufficiently effective in drying the fish. The rate of reducing moisture content of whole fish in the dryer 40 percent faster than traditional drying (open air drying) and fish fillet 37 percent faster than traditional one. The rate of water removes from the fish sample was also affected by the position of the samples in the dryer. The samples nearest to the collector have the highest moisture losses (front trays). So by using this plan, Consumer and producer of fish will gain more economic and hygienic of fish product. The fish product will be avoid from deterioration and protein losses along the drying
Telah dilakukan modifikasi terhadap teknologi pengeringan ikan di Pulau Madura. Sistem pengering tersebut terbuat dari bahan-bahan lokal seperti sabut kelapa, hardplek, seng gelombang dan plastik bening tahan panas. Alat pengering yang berdimensi 1,5m x 2,4m x 1,88m (lebar, panjang, tinggi) itu mampu melakukan pengeringan 3 kali lebih cepat dibanding pengeringan langsung (udara terbuka). Kemampuan menurunkan kadar air ikan 40 persen lebih cepat untuk ikan utuh dan 37 persen lebih cepat untuk ikan belah dibandingkan cara pengeringan tradisional. Jika dibandingkan terhadap kapasitas per satuan luas alat ini memiliki kemampuan tampung 3 kali lebih banyak dibanding pengeringan langsung (tradisional). Bagi produsen maupun konsumen alat ini memberikan nilai ekonomis yang tinggi karena produk ikan keringnya lebih higienis dan proteinnya tidak mengalami deteriorasi selama pengeringan ataupun saat penyimpanan
