Abstract. Tropospheric vertical structure was analyzed using in situ measurements of 03, CO, CH4, and H20 taken on board the NASA DC-8 aircraft during three Pacific Exploratory Missions (PEMs): PEM-West A, September-October 1991 in the western Pacific; PEM-West B, FebruaryMarch 1994 in the western Pacific; and PEM-Tropics A, September-October 1996 in the central and eastern Pacific. PEM-Tropics...
Efficient depot systems for entrapment and storage of small water-soluble molecules are of high demand for wide variety of applications ranging from implant based drug delivery in medicine and catalysis in chemical processes to anticorrosive systems in industry where surface-mediated active component delivery is required on a time and site specific manner. This work reports the fabrication of i...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
The fabrication of cobalt oxide nanotubes (length 3-4 μm, width 200-400 nm) was achieved by a colloidal templating approach. In this approach, a Co(III)-cysteinato complex [Co(en)2(S-cys)]2(BF4) was employed as the precursor of cobalt oxide. The infiltration behavior of the precursor into polyelectrolyte multilayers was studied with a quartz crystal microbalance which showed that the amount of ...
abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
Successful layer-by-layer (LbL) growth of short chain (∼30 repeat units per chain) poly(sodium styrene sulfonate) (PSS)-poly(diallyl dimethylammonium chloride) (PDADMAC) multilayers is presented for the first time and compared with the growth of equivalent long chain polyelectrolyte multilayers (PEMs). A detailed study performed by quartz crystal microbalance with dissipation (QCM-D) is carried...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Externally Bonded Reinforcement on Grooves (EBROG) is a new method that has been introduced to postpone or eliminate debonding of FRP sheets from concrete surface in concrete beams strengthened for flexure and increase loading capacity. For strengthening reinforced conceret beams in strructure, use of different types of FRP like: laminate, AFRP, CFRP, and GFRP. By there is some differences bet...
