Estimation of rainfall erosivity (R) using Geo-spatial technique for the state of Tripura, India: A comparative study

open access: yesThe Indian Journal of Agricultural Sciences, 2022
The principal-agent of soil detachment is rainfall kinetic energy (KE), which must be assessed to understand the nature of erosion, particularly in high rainfall regions, and is designated as a rainfall erosivity index (R).

The time squares sequences: a new task for assessing visuospatial working memory

open access: yesFrontiers in Behavioral Neuroscience, 2023
IntroductionSeveral studies have shown that the working memory is sensitive to temporal variations. We used a new visuospatial working memory task, the “Time Squares Sequences,” to investigate whether implicit variations in stimuli presentation time ...

Temporal Variations of Stroke Occurence [PDF]

open access: yesSerbian Journal of Experimental and Clinical Research, 2017
Abstract Stroke is one of leading causes of death worldwide. Different frequency of stroke occurence is observed in days of the week and months in the year, and incidence of stroke has irregular time pattern. We analyzed 516 patients who had acute stroke and were treated in Clinic of Neurology, Clinical Center Kragujevac from January 1,

Occurrence and Discrepancy of Surface and Column Mole Fractions of CO2 and CH4 at a Desert Site in Dunhuang, Western China

open access: yesAtmosphere, 2022
Carbon dioxide (CO2) and methane (CH4) are the two major radiative forcing factors of greenhouse gases. In this study, surface and column mole fractions of CO2 and CH4 were first measured at a desert site in Dunhuang, west China.

Evolution of size-dependent flowering in a variable environment: partitioning the effects of fluctuating selection [PDF]

open access: yes, 2004
In a stochastic environment, two distinct processes, namely nonlinear averaging and non-equilibrium dynamics, influence fitness. We develop methods for decomposing the effects of temporal variation in demography into contributions from nonlinear ...
