Developmental Validation of the Quantifiler® Duo DNA Quantification Kit for Simultaneous Quantification of Total Human and Human Male DNA and Detection of PCR Inhibitors in Biological Samples*

Abstract: The Quantifiler^® Duo DNA Quantification kit enables simultaneous quantification of human DNA and human male DNA as well as detection of inhibitors of PCR in a single real-time PCR well. Pooled human male genomic DNA is used to generate standard curves for both human (ribonuclease P RNA component H1) and human male (sex determining region Y) specific targets. A shift in the cycle threshold (C_T) values for the internal positive control monitors the presence of PCR inhibitors in a sample. The assay is human specific and exhibits a high dynamic range from 0.023 to 50 ng/μL. In addition, the multiplex assay can detect as little as 25 pg/μL of human male DNA in the presence of a 1000-fold excess of human female DNA. The multiplex assay provides assessment of the DNA extract and guidance for the selection of the appropriate AmpFℓSTR^® Amplification Kit to obtain interpretable short tandem repeat profiles.     

An Economic Analysis of State and Individual Responsibility Under International Law

The international law of state responsibility determines whenstates are liable for international law violations. States aregenerally liable when they have control over the actions ofwrongdoers; thus, the actions of state officials can implicatestate responsibility whereas the acts of private citizens usuallydo not. We argue that the rules of state responsibility havean economic logic similar to that of vicarious liability indomestic law: the law in both cases provides third parties withincentives to control the behavior of wrongdoers whom they canmonitor and influence. We also discuss international legal remediesand individual liability under international criminal law.

The Global Era of National Policy and the Pan-Oceanic National Fleet

This article develops a framework for considering the future requirements for U.S. maritime power. It does so by proposing that these requirements must be considered within the context of an integrated National Fleet—the combined capabilities of the three “Sea Services”—the U.S. Navy, U.S. Marine Corps, and U.S. Coast Guard. It also would include their reserve components, as well as the Military Sealift Command (MSC) and the Maritime Administration's Ready Reserve Force (RRF)—the two organizations responsible for maintaining the nation's strategic sealift fleet.

A note on crop mixtures under indigenous conditions in Northern Nigeria

This note contends that crop mixtures are employed by farmers primarily as risk precautions and that the immediate objective of farmers is not only one of profit maximisation but also of stability of income. The results of an income stability model employed to verify this hypothesis seem to agree relatively well with existing information in parts of Northern Nigeria.
