We have studied the value of the Hubble constant using the KLUN (Kinematics of the Local Universe) sample of 5171 spiral galaxies having isophotal diameters D25 (and partially B-magnitudes), H i line widths, and radial velocities. The sample is diameter-limited, complete down to D25 = 1.6 arcmin. As in the first similar study, where a much smaller magnitude-limited sample was used (Bottinelli e...
زمینه وهدف: حوادث قلبی ناشی از بیماری عروق کرونر شایعترین علت مرگ و میر در دنیا میباشد. ازطرفی کمبود ویتامین d به عنوان یکی از عوامل موثر در بروز این بیماری مشخص شده است. با توجه به شیوع بالای کمبود این ویتامین در ایران در این مطالعه به بررسی میزان شیوع کمبود ویتامین d در بیماران تحت آنژیوپلاستی، تاثیر جنسیت در این مورد و رابطه آن با شدت بیماری عروق کرونری میپردازیم. مواد و روشها: در این مط...

Place names are often used to describe and to enquire about SPIRIT project D24 3301 Modelling vague places with knowledge from the web IST-2001-35047 v 1.1 Page 2 of 29 geographical information. Geographical place name ontologies, such as gazetteers and geographical thesauri, can help automate geographical information retrieval tasks that employ place names. Most gazetteer resources encoding kn...
We present results from the analysis of deep ROSAT HRI and PSPC observations of the spiral galaxy M81. The inferred total (0.5–2 keV band) luminosity of M81 is ∼ 3×10 ergs s, excluding the contribution from identified interlopers found within the D25 ellipse. The nucleus of the galaxy alone accounts for about 65% of this luminosity. The rest is due to 26 other X-ray sources (contributing ∼ 10%)...
We present the first low-luminosity [LX > (5 10) ; 10 ergs s ] X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for two typical old elliptical galaxies, NGC 3379 and NGC 4278. Because both galaxies contain little diffuse emission from hot ISM and no recent significant star formation (hence no high-mass X-ray binary contamination), they provide two of the best homo...
The objectives of this study were to evaluate the influence of diet composition on ruminal parameters, more particularly redox potential (Eh). Four Holstein dry dairy cows, fitted with ruminal cannulas, were allocated in a 4 × 4 Latin square design. They were given four experimental hay-based diets D0, D25, D42 and D56 consisting of 0%, 25%, 42% and 56% of ground wheat and barley concentrate mi...
We present the properties of the discrete X-ray sources detected in our monitoring program of the globularcluster (GC) rich elliptical galaxy, NGC 4278, observed with Chandra ACIS-S in six separate pointings, result-ing in a co-added exposure of 458-ks. From this deep observation, 236 sources have been detected within theregion overlapped by all observations, 180 of which lie within...
سابقه و هدف: این مطالعه به منظور ارزیابی وضعیت ویتامینd در کودکان دبستانی 12-9 ساله شهر تهران در پاییز و زمستان 1387-1386 انجام شد. مواد و روش ها: این مطالعه توصیفی مقطعی بر روی 1111 بچه 12-9 ساله (573 پسر و 538 دختر) تهران انجام شد. مصرف کلسیم غذایی با استفاده از ffq در 503 نفر از افراد مورد مطالعه تعیین شد. کمبود ویتامین d بر اساس سطوح سرمی اولیه 25 هیدروکسی ≥ nmol/l 37 (معیار اول) یا ≥ nmol/...
