Assessment of lighting levels in residential and public buildings (based on the example of Yekaterinburg)

The article describes the results of assessing lighting in residential and public building and its potential effects on workers with account for their various fields of activity. Artificial lighting was measured in various rooms taking into account the use of the main light sources. The study showed that the use of LED lamps provided a sufficient lighting level and had the most favorable effect on humans.В статье представлены результаты выполненной оценки фактора освещённости в жилых и общественных зданиях, возможного влияния на работников с учётом различных сфер деятельности. Организовано и проведено измерение искусственной освещенности в различных помещениях с учётом использования различных основных источников света. В результате исследования показано, что использование светодиодных ламп обеспечивает достаточный уровень освещённости и оказывает максимально благоприятное влияние на организм человека

Long-Term Relationships between Synaptic Tenacity, Synaptic Remodeling, and Network Activity

Long term time-lapse imaging reveals that individual synapses undergo significant structural remodeling not only when driven by activity, but also when network activity is absent, raising questions about how reliably individual synapses maintain connections

Microglial Interactions with Synapses Are Modulated by Visual Experience

Microglia, the brain's immune cells, show unique interactions with nearby synaptic elements under non-pathological conditions that are sensitive to changes in sensory experience

Dendritic spine loss and synaptic alterations in Alzheimer's disease

Dendritic spines are tiny protrusions along dendrites, which constitute major postsynaptic sites for excitatory synaptic transmission. These spines are highly motile and can undergo remodeling even in the adult nervous system. Spine remodeling and the formation of new synapses are activity-dependent processes that provide a basis for memory formation. A loss or alteration of these structures has been described in patients with neurodegenerative disorders such as Alzheimer's disease (AD), and in mouse models for these disorders. Such alteration is thought to be responsible for cognitive deficits long before or even in the absence of neuronal loss, but the underlying mechanisms are poorly understood. This review will describe recent findings and discoveries on the loss or alteration of dendritic spines induced by the amyloid beta (Abeta) peptide in the context of AD

Optical properties of KPb2Cl5KPb_2Cl_5 and RbPb2Cl5RbPb_2Cl_5 single crystals in the far ultraviolet spectral region

Electronic structure properties of undoped single crystals of KPb2Cl5 (KPC) and RbPb2Cl5 (RPC) have been studied using low-temperature (T=8°K) far ultraviolet (3.7–24 eV) synchrotron radiation spectroscopy. Dispersions of optical functions have been calculated. The electronic transitions at 4.4–5.0 eV were ascribed to the excitation of cationic excitons. The energy region of 5–9 eV was associated with the transitions from the valence band to the conduction band: 6S10→6P11 at 6.28 eV, 6S10→6P32 at 5.94 eV. The complex band at 7.87 eV was attributed to the excitation of anionic excitons. The 19–24 eV peaks were associated with the 5d→6p transitions in Pb2+ ions
