Several fog episodes occurred in California’s San Joaquin Valley during winter 2000/2001. Measurements revealed the fogs to generally be less than 50 m deep, but to contain high liquid water contents (frequently exceeding 200 mg/m) and large droplets. The composition of the fog water was dominated by ammonium (median concentration= 608 μN), nitrate (304 μN), and organic carbon (6.9 ppmC), with ...
Prime task for orthopedists and traumatologists is the development of new artificial materials for replacement of osseous tissue and cartilage defects, for functional rehabilitation of the injured locomotorium tissue after traumatic fractures and surgical interventions. Electron beam (EB) processing of polymer composites with bioactive ceramics was used for manufacture of new artificial materia...
The technology of electro-processing by UV-radiation soil agricultural plants is considered. mechanism the effect UV irradiation to change redox reactions a chemical potential shown. As result experimental researches, optimum parameters for processing soils with ultraviolet radiation lamps increasing absorption most mobile manganese forms in are defined.
the purpose of the present study was to see which one of the two instruction-processing instruction (pi) and meaningful output based instruction (mobi) accompanied with prompt and recast- is more effective on efl learners’ writing accuracy. in order to homogenize the participants in term of language proficiency a preliminary english test (pet) was administrated between 74 intermediate students ...
Introduction and purpose: The growing use of ionizing radiation in disease diagnosis necessitaes the appropriate use of devices and awareness regarding the principles of radiation protection. With appropriate adoption of personal protection equipment and compliance with the existing regulations in relation to protection of the buildings where sources of ionizing radiation ar...
