One of the purposes of consciousness is to acquire knowledge. The models of this task traditionally assume a division between the known and the knower, a division that leads into doubtful reasoning about some kind of (frequently disguised) homunculus. The current paper tries to avoid such fallacies by viewing the adaptation of the mind as an evolutionary process, a process distinct (but not ind...
Land surface albedo is a key parameter representing the outgoing solar flux fractions reflected by earth surface . It is widely used as an input parameter for numerical radiation budget models, the hydrological cycle and climate modeling studies. Urban’s high albedo changes the original land surface radiation balance, high thermal diffusivity insulates the ground, and thus it represents a dry, ...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
Albedo is one of the variables controlling the mass balance of temperate glaciers. Multispectral imagers, such as MODerate Imaging Spectroradiometer (MODIS) on board the TERRA and AQUA satellites, provide a means to monitor glacier surface albedo. In this study, different methods to retrieve broadband glacier surface albedo from MODIS data are compared. The effect of multiple reflections due to...
Seasonal snow cover in the Northern Hemisphere is the largest component of the terrestrial cryosphere and plays a major role in the climate system through strong positive feedbacks related to albedo. The snow-albedo feedback is invoked as an important cause for the polar amplification of ongoing and projected climate change, and its parameterization across models is an important source of uncer...
