The main purpose of this study is to investigate the quantitative and qualitative characteristics of dominant tree species and their regeneration status in the Arasbaran forests. Data were collected by transect sampling and regeneration was assessed by plot with an area 100 m2. In the sample plots, we recorded information on species type, diameter at breast height, height, quality of seedlings ...
In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...
Statement of Problem: In a previous study it was reported that a durable resin-ceramic tensile bond could be obtained by an appropriate silane application without the need for HF acid etching the ceramic surface. Evaluation of the appropriate application of silane by other test methods seems to be necessary. Purpose: The purpose of this study was to compare the interfacial fracture toughness of...
In order to investigate the interaction effect of salinity and supplementary calcium nitrate on growth, quantitative and qualitative attributes of flowers and mineral composition of Rosa hybrida ‘Ilona’, a factorial experiment was carried out in completely randomized design with three replications. Treatments consisted of four sodium chloride rates (0, 5, 10 and 20 mM sodium chloride) and four ...
Goat warble-fly infestation is caused by przhevalskiana silenus (Diptra Oestridae) larvae and it is characterized by the presence of warble under the hide of the back and flanks of the animal. This study was carried out from March 2009 to March 2010 on the hides sent to the khorasn leather industries for grading, processing and tanning. This study demonstrated from 340,797 goat hides e...
In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, three-dimensional hybrid guided modes can be calculated by us...
To investigate the influence of salinity and calcium (Ca) on some properties of Plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in Jiroft, south of KermanProvince, Iran. Three salinity levels of 0, 100 and 200 mM NaCl and Ca levels of 0, 5 and 10 mM Calcium nitrate wereapplied as the first and second factors, respectively. ...
The aim of this research was to study how water use management can increases vegetation cover inrainwater catchment systems. The study was conducted through comparison of two methods of irrigation, i.e. traditional sub-surface drip irrigation and drip irrigation. Three soil samples were taken and analyzed from three locations in north of Sistan from a depth of 50 cm. A furrow was dug with a bas...
We discovered ferromanganese nodules that measure up to 46 cm in diameter with stromatolitic growth patterns in the western central near-shore portion of Second Connecticut Lake, Pittsburg, New Hampshire. They occur as four distinct morphotypes: irregular laminated convex plates that form concentric rings around a nucleating center ("domed-plate"), continuous pustular pavements that extend >10 ...
The extents of functional surfaces (villi, microvilli) have been estimated at different longitudinal sites, and in the entire small intestine, for three species of bats belonging to two feeding groups: insect- and fruit-eaters. In all species, surface areas and other structural quantities tended to be greatest at more cranial sites and to decline caudally. The entomophagous bat (Miniopterus inf...
