Under the cold impact of liquid nitrogen, the shale suffers from the significant freezing damage, which provides the possibility of liquid nitrogen fracturing.Moreover, shale fracturing assisted by liquid nitrogen can effectively reduce reservoir pollution.In this paper, the hydraulic fracturing experiments of natural shale samples Resistance Brake
Lantibiotics continue to offer an untapped pipeline for the development of novel antibiotics.We report here the discovery of a novel lantibiotic for the treatment of C.difficile infection (CDI).The leads were selected from a library of over 300 multiple substitution variants of the lantibiotic Mutacin 1140 (MU1140).Top performers were selected base
Basketball - Accessories According to recent reports, K-12 full-time virtual school students have shown lower performance in math than their counterparts in regular brick-and-mortar schools.However, research is lacking in what kind of programmatic interventions virtual schools might be particularly well-suited to provide to improve math learning.En
A persistent question in epigenetics is how heterochromatin is targeted for assembly at specific domains, and how that chromatin state is faithfully transmitted.Stable heterochromatin is necessary to silence transposable elements (TEs) and maintain genome integrity.Both the RNAi system and heterochromatin components HP1 (Swi6) and H3K9me2/3 are req
In this Round Dining Table work, we present the seismic catalogue compiled for Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Turkmenistan) in the framework of the Earthquake Model Central Asia (EMCA) project.The catalogue from 2000 B.C.to 2009 A.D.is composed by 33,034 earthquakes in the MLH magnitude (magnitude by surface waves
