Preservation variance of soil DNA is neglected in the literature, and exceptional cases exaggerate amplification capabilities. This study sought to amplify a short mitochondrial fragment (212 bp) specific to Sus scrofa domesticus from the soil surrounding decomposing pig remains from an open‐air locale. Samples collected above the body at incremental distances after 145 days of initial placement yielded pig DNA. A secondary sampling was collected in 2017, approximately 768 days after burial. Inhibition tests corroborated that pig DNA was no longer present in the soil resulting in a loss of original DNA between 145 and 768 days. The results provide evidence that genetic material leaches out radially from the source and DNA fragments longer than 200 bp do not persist in soil for a relatively short timeframe in western Montana. The conclusions support the collection of soil in crime scene investigation procedures within the first few months of decomposition.  相似文献

Abstract

In July 1977, newly elected President Jimmy Carter suddenly found himself confronted with a difficult neutron bomb decision. With a narrow victory in Congress, pro neutron‐bomb forces had successfully presented the President with the authority to proceed with production. Unfortunately, as the months passed, Carter failed to move swiftly with production of the neutron warheads which many NATO alliance members saw as a much needed deterrent to the Warsaw PACT'S massive armor superiority.

Confronted with mounting international and domestic opposition to the neutron weapon, Jimmy Carter, in the fall of 1977, insisted that the NATO allies officially support American production of the warheads before the United States would produce it. Spurred on by Carter's indecision and by certain NATO members’ reluctance to officially support the weapon, the Soviet Union shifted its propaganda machine into high gear in a massive effort to sway international opinion against the weapon.

During the first few months of 1978, Western Europe saw a flood of protests against this so‐called “inhumane” weapon. Domestic communist and left‐wing socialist opposition to the neutron bomb precipitated a precarious right‐left split within many Western European socialist parties. Nowhere was this split more graphically illustrated than within the ruling West German Social Democratic Party (SPD). Chancellor Helmut Schmidt and his moderate technocrats basically favored the neutron bomb, but feared crippling left‐wing SPD opposition and possible defections if West Germany complied with American demands to break with over 30 years of U.S.‐West German nuclear precedent and agree officially to American production of a nuclear weapon, the neutron bomb.

Only after much American cajoling did the allies move toward official NATO support for production. Carter had failed to understand the disastrous political implications which left‐wing opposition had created within the NATO countries and refused to let Schmidt and other leaders off the hook. And then in an amazing move, after Schmidt and the NATO allies had risked political ruin to reach an agreement to support the neutron bomb, President Carter pulled the rug from under them on April 7,1978, when he indefinitely delayed a decision on the weapon.

With this decision, Carter had set a dangerous precedent by yielding to Soviet pressure and had missed an opportunity to win the favor of skeptical NATO allies and critics who asserted he was too weak and indecisive. But above all, Carter had unnecessarily alienated and angered NATO leaders like Schmidt who risked possible political ruin by supporting the neutron bomb.  相似文献

The authors ground their reflections on gender and the complex realities of the second Palestinian intifada against Israeli occupation in the political processes unleashed by the signing of the Israeli–Palestinian rule, noting that the profound inequalities between Israel and Palestine during the interim period produced inequalities among Palestinians. The apartheid logic of the Oslo period – made explicit in Israel's policies of separation, seige and confinement of the Palestinian population during the intifada and before it – is shown to shape the forms, sites and levels of resistance which are highly restricted by gender and age. In addition, the authors argue that the Palestinian Authority and leadership have solved the contradictions and crisis of Palestinian nationalism in this period through a form of rule that the authors term ‘authoritarian populism’, that tends to disallow democractic politics and participation. The seeming absence of women and civil society from the highly unequal and violent confrontations is contrasted with the first Palestinian intifada (1987–91), that occurred in a context of more than a decade of democratic activism and the growth of mass-based organizations, including the Palestinian women's movement. The authors explore three linked crises in gender roles emerging from the conditions of the second intifada: a crisis in masculinity, a crisis in paternity and a crisis in maternity.  相似文献

“在马身上,你希望的和你得到的往往是两回事。”我的丈夫贝尔经常这样对我说,但是产马驹的季节的确是一个充满梦想的季节。当我们开始在我们的农场上养appaloosas(马的一种)时,我就梦想着蓝色的缎带和迫不及待的买主。第一年,几只小appaloosas身上斑斓的色彩把农场打扮成了一个会动的花园。它们的脸上、身上闪动着各色的斑点,如同穿着一件碎花衣裳。  相似文献
