On the derivation of an hourly local index to define the normal ionosphere
reference ionosphere ionospheric disturbance ionospheric indices
2015/9/30
In this paper an hourly local ionospheric index f n F 2 is proposed to define the normal level of the undisturbed
ionosphere. For the determination of this index a model is developed where the normal...
Derivation of Instantaneous Unit Hydrograph for a sub-basin using Linear Geomorphological Model and Geographic Information Systems
Geographic Information System GIS Linear Geomorphological Model LGM GIUH
2015/8/14
Rainfall is converted into runoff and reaches the river and it becomes river flow. Geomorphological Instantaneous Unit Hydrograph (GIUH) based approach, which uses the geomorphologic parameters, is us...

The Direct Reprogramming of Somatic Cells: Establishment of a Novel System for Photoreceptor Derivation
development genetic photoreceptor regeneration reprogramming retina
2015/5/22
Photoreceptors are a class of sensory neuronal cells that are deleteriously affected in many disorders and injuries of the visual system. Significant injury or loss of these cells often results in a p...
Growth of Ovarian Primary Follicles Retrieved from Neonates of Different Ages and Derivation of Mature Oocytes Following In vitro-Culture
Neonatal Mouse Ovary Primary Follicle In vitro Culture Oocyte Maturation

This study was conducted to improve the yield of mature oocytes from in vitro-culture of ovarian primary follicles by optimizing follicle retrieval from neonatal mice of different ages. Primary follic...
Non-Gaussian statistics, maxwellian derivation and stellar polytropes
Non-Gaussian statistics maxwellian derivation stellar polytropes Space Physics
2012/5/29
In this letter we discuss the Non-gaussian statistics considering two aspects. In the first, we show that the Maxwell's first derivation of the stationary distribution function for a dilute gas can be...
