today, persian poetry is of great importance to many scholars around the world. the interest and attention of various cultures toward such a fine literature has given quite a good motivation for a comparative study. the major concern of the study is to investigate how nature is depicted through the works of the great english poet, william wordsworth (1770-1850) and the outstanding contemporary ...
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
For the Schwarzschild black hole, Bekenstein–Hawking entropy is proportional to area of event horizon. holes with two horizons, thermodynamics not very clear, since role inner horizons well established. Here we calculate Reissner–Nordström hole and Kerr which have horizons. spherically symmetric used several different approaches. All them give same result for corresponding temperature thermal H...
We examined the composition and concentration of amino acids by soil horizon and depth on the Tanana River floodplain in interior Alaska. Soils from mid-successional stages of balsam poplar and white spruce were separated into successive forest floor (Oe/Oa), buried organic horizons (BOHs), and mineral horizons; and water-extractable amino acid composition and concentration were determined by H...
A very acidic soil under an adult spruce (Picea abies) stand, in the Basses-Vosges (North-eastern France), was analysed in 1986, and ten years later in 1996. The chemical composition of the mineral horizons did not show much variation, but the sum of exchangeable Ca and Mg in the mineral horizons and their total contents in the OL, OF and OH horizons decreased significantly. In ten years, the M...

A general definition of a black hole is given, and general ‘laws of black-hole dynamics’ derived. The definition involves something similar to an apparent horizon, a trapping horizon, defined as a hypersurface foliated by marginal surfaces of one of four non-degenerate types, described as future or past, and outer or inner. If the boundary of an inextendible trapped region is suitably regular, ...
Comparing the ability of ST and WRB systems to describe soils with clay-enriched horizons was the aim of the present research. In arid and semi-arid regions of Iran, two study sites were considered. Three pedons at each study site were selected, described and sampled. Soils were classified based on ST (2014) and WRB (2015) systems. The micro-morphological investigations were done to confir...
Chruściel and Galloway constructed a Cauchy horizon that is nondifferentiable on a dense set. We prove that in a certain class of Cauchy horizons densely nondifferentiable Cauchy horizons are generic. We show that our class of densely nondifferentiable Cauchy horizons implies the existence of densely nondifferentiable Cauchy horizons arising from partial Cauchy surfaces and also the existence o...
