in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
Cooling greenhouses is essential to provide a suitable environment for plant growth in arid regions characterized by brackish water resources. However, using conventional cooling methods are facing many challenges. Filtering out near infra-red radiation (NIR) at the greenhouse cover can significantly reduce the heating load and can solve the overheating problem of the greenhouse air. This paper...
Countries located in the Mediterranean region share many common features terms of agricultural sustainability and economic realities modern farming, as they are affected by water scarcity, energy use climate suitability. Greenhouses considered a mitigation measure to combat change sustainable production system. The majority greenhouses rudimentary, while those Central North Europe characterized...
Botrytis cinerea is an important pathogen that causes diseases in ornamental crops. In presentresearch several greenhouses of roses located in central region of Iran were surveyed toidentify the Botrytis cinerea. A total of 80 isolates were collected from rose greenhouses incentral region of Iran. Morphological identification was based on characters such asconidiophore and conidial length. Acco...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
in the present study, for the first time, we document discovery of the predatory mite n. californicus in some rose greenhouses in yasouj, iran. furthermore, variation in spermathecal calyx shape is also discussed.
