Many real-world systems undergo abrupt changes in dynamics as they move across critical points, often with dramatic and irreversible consequences.Much existing theory on identifying the time-series signatures of nearby critical points, such as increased signal variance and slower timescales, is derived from analytically tractable systems, typically
Compound osteoderms preserved in amber reveal the oldest known skink
Abstract Scincidae is one of the most species-rich and cosmopolitan clades of squamate reptiles.Abundant disarticulated fossil material has also been attributed to this group, however, no complete Braces pre-Cenozoic crown-scincid specimens have been found.A specimen in Burmite (99 MYA) is the first fossil that can be unambiguously referred to this
An overview of prisons, prisoners and international human rights standards
This article examines the principal international human rights standards that exist for the treatment of prisoners.Given the increase in the use of imprisonment in many countries, the administration of prisons poses certain challenges.The author addresses this issue by first examining the purposes of imprisonment, which is the only way to evaluate
Isolation and Amplification of Touch DNA from Portable Computer
Analysis of touched DNA from crime scenes is fundamental in forensic DNA laboratories.Many factors affect the recovery of DNA from touched surfaces and then affect the quality of the final results.The aim of this work is studying the possibility of recovery suitable amount of DNA from MAG CITRATE 150MG ltouched portable computer.The computer was cl
Identification and distribution of whiteflies (Hemiptera: Aleyrodidae) in tomato crops (Solanum lycopersicum) in Cundinamarca (Colombia)
The main purpose of this study was to determine the presence, distribution and characterization of whiteflies in thirteen tomato-crop producing municipalities in Cundinamarca (Colombia).Immature stages were collected and taken to the laboratory until adults emerged in order to establish their taxonomic identification.The mitochondrial regions were
