X-ray and radio prompt emission from a hypernova SN 2002ap

Here we report on combined X-ray and radio observations of SN 2002ap with XMM-Newton ToO observation and GMRT observations aided with VLA published results. In deriving the X-ray flux of SN 2002ap we account for the contribution of a nearby source, found to be present in the pre-SN explosion images obtained with Chandra observatory. We also derive upper limits on mass loss rate from X-ray and radio data. We suggest that the prompt X-ray emission is non-thermal in nature and its is due to the repeated compton boosting of optical photons. We also compare SN's early radiospheric properties with two other SNe at the same epoch.Comment: 4 pages, 5 figures. Uses espcrc2.sty.

Hadis-hadis Ekologi Dalam Konteks Perindustrian Di Indonesia

As the religion of rahmatan lil ‘alamin, Islam does not only concern with how mankinds worship to Allah (ibadah), and establish relationship among mankinds (muamalah) but also protect and preserve ecological systems around them as main purposes of Islamic laws (maqashid al-syari\u27ah). As the best role model (uswah al-hasanah), Prophet Muhammad pbuh has shown especially how to deal with ecology in relation to industrial activities. As a predominantly Moslem country, hadeeth as a religious text is expected to a great influence on the way of life including industrial world in order to realize public welfare and prosperity by industrial practitioners in Indonesia in general. However, religious passion has not had a positive impact in industrial world. Welfare as the main goal can only be enjoyed by a small group of people. Dealing with the phenomena, this article, therefore, aims at discussing hadeeths in relation to ecology and presenting analysis the implementation of the hadeeths in industrial practices in Indonesi

Novel spectral kurtosis technology for adaptive vibration condition monitoring of multi-stage gearboxes

In this paper, the novel wavelet spectral kurtosis (WSK) technique is applied for the early diagnosis of gear tooth faults. Two variants of the wavelet spectral kurtosis technique, called variable resolution WSK and constant resolution WSK, are considered for the diagnosis of pitting gear faults. The gear residual signal, obtained by filtering the gear mesh frequencies, is used as the input to the SK algorithm. The advantages of using the wavelet-based SK techniques when compared to classical Fourier transform (FT)-based SK is confirmed by estimating the toothwise Fisher's criterion of diagnostic features. The final diagnosis decision is made by a three-stage decision-making technique based on the weighted majority rule. The probability of the correct diagnosis is estimated for each SK technique for comparison. An experimental study is presented in detail to test the performance of the wavelet spectral kurtosis techniques and the decision-making technique

Enumeration of States in a Periodic Glass

We present an analytic enumeration of the metastable states, $N_s$, in a periodic long-range Josephson array frustrated by a transverse field. We find that the configurational entropy, $S_{conf} \equiv \ln N_s$, is extensive and scales with frustration, confirming that the non-random system is glassy. We also find that $S_{conf}$ is different from that of its disordered analogue, despite that fact that the two models share the same dynamical equations

Suitability of high-pressure xenon as scintillator for gamma ray spectroscopy

In this paper we report the experimental study of high-pressure xenon used as a scintillator, in the context of developing a gamma ray detector. We measure a light yield near 2 photoelectrons per keV for xenon at 40 bar. Together with the light yield, we also measured an energy resolution of ~9% (FWHM) at 662 keV, dominated by the statistical fluctuations in the number of photoelectrons.Comment: 15 pages, 11 figure

Gambaran Hasil Pemeriksaan Sitologi Penderita Kanker Serviks Pasca Terapi Radiasi Berdasarkan Kelompok Umur Di Instalasi Radioterapi RSUD Arifin Achmad Periode Tahun 2009–2013

Radiation therapy is a therapeutic option for cervical cancer, and expected to have optimal outcomes, The results of radiation therapy is different for each patient depending on the sensitivity of cancer cells to radiation that is influenced by age, it can be reviewed by looking at the cell\u27s response to radiation based on the presence or absence of Malignant cells that found in the results of cytologic examination after radiation therapy. This research aimed to describe the results of cytological examination of cervical cancer patients after radiation therapy by age group in Radiotherapy Installation Arifin Achmad general hospital of Riau Province Period 2009-2013. The type of this research was descriptive retrospective with population are medical recodrs of cervical cancer patients who had undergone radiation therapy in the form of 25 full time external radiation therapy without chemotherapy in Radiotherapy Installation Arifin Achmad General Hospital of Riau period 2009 to 2013. The sample is the medical record that eligible as population that is as much as 78 medical records. The result of this research was found the largest age group who performed radiation therapy was 40-49 years old (41%), while the largest age group who have a cytological examination found no Malignant cells most is 40-49 years old (12.8%), the age group that has the results Malignant cells are found in the form of the age group 40-49 years old and 50-59 years old with patients respectively (1.3%) and the largest age group who do not have the data post-radiation cytology result is 40-49 years old (26 , 9%). The largest age group who have a cytological examination found no Malignant cells most is people who do a cytological examination more than once that is age group > 60 years old (55.6%) and resulted in the Malignant cells are found in the age group 50-59 years old (11 , 1%)
