Just Posting in the Same Place: Confronting the Paucity of Collaborative Behavior in US K-12 Wikis,51 publicly viewable, education-related wikis. Aided by computational tools, trained human coders conducted a large-scale content analysis examining every revision to every page of each of these 406 wikis. Seven types of student collaborative behavior were found in these wikis: . and .. These behaviTorrid 发表于 2025-3-25 17:11:48
,Geochemistry of Mafic–Felsic Rocks of Phulad Ophiolite, in and Around Pindwara-Mount Abu Region, Sos shear zone referred to as Phulad ophiolite. This ophiolitic sequence has been in debate since the day of its nomenclature in the map of Geological Survey of India for the non-preservation of various members of an ophiolite suite. Present study suggests that all lithomembers of an ophiolite are pre大约冬季 发表于 2025-3-25 21:56:00
Effect of Annealing on the Morphology and Properties of Thermoplastic Polyurethanes,atures but may be processed by injection molding at elevated temperatures. Many of the unique properties of these materials are attributed to a microphase separation of the segments into “hard” urethane domains which are surrounded by a “soft” polyester or polyether matrix. Because of their commerciAGOG 发表于 2025-3-26 01:31:06

Risk Informed In-Service Inspection of PWR Nuclear Power Plant Piping Components Subjected to Erosioperature, pH value, flow velocity, and model error are considered as random variables. From the results obtained, it is noted that there is a need to consider the correlation between degradation at two successive times for obtaining conservative estimates of failure probability against rupture.Disk199 发表于 2025-3-26 17:35:54
CH2-Symmetric/CH2-Antisymmetric Stretch Ratio Sensor for Cell Analysis,nd even between the two tumor types). The developed LED-photodiode based infrared absorbance sensor could be used for quick pre-screening of biopsy samples which, compared to labeling and staining techniques, does not require highly trained personnel and is much cheaper than liquid nitrogen cooled FTIR spectroscopes.
