purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

This paper presents a new system for indoor location of a mobile device based on bluetooth technology. Bluetooth access points of a network are used for the location system and to access the network. Location is made by means of the signal strength received from those access points. The signal energy will be measured by the mobile device and it will be transmitted to a central server that calcu...

The prototype effect in face recognition refers to a tendency to recognize the face corresponding to the central value of a series of seen faces, even when this central value or prototype has not been seen. Five experiments investigated the extension and limits of this phenomenon. In all the experiments, participants saw a series of faces, each one in two or more different versions or exemplars...

The location of central respiratory chemoreceptors in amphibian larvae may change as the central chemoreceptive function shifts from driving gill to driving lung ventilation during metamorphosis. We examined this possibility in the in vitro brain stem of the pre- and postmetamorphic Rana catesbeiana tadpole by microinjecting hypercapnic artificial cerebrospinal fluid (aCSF) while recording fict...

Our climate is strongly influenced by the manner in which solar radiation is absorbed and scattered in the Earth’s atmosphere. Atmospheric aerosols play an important role in modifying the radiation budget of the earth-atmosphere system. Aerosols have a direct impact on the atmosphere as they scatter and absorb solar and infrared radiations and indirectly affect the size distribution of cloud dr...
