The central region of NGC 1365 has been mapped in the J = 3 − 2 CO emission line with the 15 m SEST, which has a HPBW of 15′′ at the frequency of this transition. The observing grid has a 5′′-spacing in the inner and a 10′′-spacing in the outer region. A deconvolved map has been produced using the Maximum Entropy Method (MEM). A circumnuclear molecular torus with a radius of about 6. ′′5 is the...
Context. High-resolution X-ray observations in the imaging and spectral domain have recently opened a new window on active galactic nuclei (AGN) feedback onto the circumnuclear gas. Spectral diagnostics, as well as the remarkable morphological coincidence between [O iii] and X-rays, point to AGN photoionisation as the dominant ionisation mechanism on scales as large as a few kpc. Aims. In this ...
The Ames Seralyzer uses solid phase chemistry coupled with reflectance spectroscopy to measure levels of serum alanine aminotransferase (serum ALT). The study reported here was carried out to evaluate the performance of the Seralyzer method compared to conventional analyses carried out on a Coulter Dacos discrete random access analyser using Boehringer (BCL) reagents conforming to SCE specicati...
Results from observations of two nearby, low X-ray luminosity Seyfert-type galaxies, namely, NGC 1365, and NGC 4051, using the ROSAT High Resolution Imager (HRI) are presented. The observations carried out with the aim of detecting and resolving the extra-nuclear (beyond the central 5–10) X-ray emission show evidence for an extended component of ≃2 kpc size in NGC 1365 and NGC 4051. The extende...

The principal objective of our study was to optimise a municipal activated sludge wastewater treatment plant (WWTP) to face high organic flows due to viticulture effluents inputs. Treatment file optimization consisted in testing different treatment lines, changing the number and volume of biological basins and clarifiers, with or without a buffer basin upstream, with a view to achieving a bette...
We present an X-ray spectral and spatial analysis of the composite starburst/Seyfert galaxy NGC1365. Excellent fits of the ROSAT PSPC spectrum are obtained by combining a soft thermal component with a hard powerlaw. The hard component may be either seen directly or can be explained by scattering of the AGN powerlaw at circumnuclear warm high-column-density gas. A compilation of the multi-wavele...
دراین پژوهش که با هدف بررسی سطح و روند تحولات باروری که برحسب شاخص t.f.rمشخص شده است - درشهرستانهای استان مرکزی و عوامل اقتصادی - اجتماعی و جمعیت شناختی موثر برآن صورت گرفت، پس از بیان مسئله و تبیین اهمیت موضوع پژوهش و ضرورت پرداختن به آن ، بر کاهش موالید و باروری در ایران و عوامل موثر برآن ، سپس به باروری و نقش آن در فرایند تحولات جمعیت ایران اشاره گردید. در فصل اول از بخش دوم ، مروری داشت...
