The DNA damage clamp loader replication factor C (RFC-Rad24) consists of the Rad24 protein and the four small Rfc2-5 subunits of RFC. This complex loads the heterotrimeric DNA damage clamp consisting of Rad17, Mec3, and Ddc1 (Rad17/3/1) onto partial duplex DNA in an ATP-dependent manner. Interactions between the clamp loader and the clamp have been proposed to mirror those of the replication cl...

We time-studied a Cat 950F and a Cat 528 grapple skidder as extraction devices for moving bunched whole trees to a landing in a short rotation eucalyptus plantation. The front-end loader was 40 to 60% more productive than the grapple skidder, depending on extraction distance. Alternatively, the single loader could both extract trees and handle the landing duties such as moving residues whereas ...

Traditional loaders with engines present the drawbacks of high energy consumption and poor emissions performance. The usage an electric motor instead engine in loader can effectively improve efficiency emissions. is mainly used earthwork construction unstructured roads. Compared to automobile, during working process loader, load fluctuates violently, vibration serious. A large torque range oper...

The Saccharomyces cerevisiae Rad24 and Rad17 checkpoint proteins are part of an early response to DNA damage in a signal transduction pathway leading to cell cycle arrest. Rad24 interacts with the four small subunits of replication factor C (RFC) to form the RFC-Rad24 complex. Rad17 forms a complex with Mec3 and Ddc1 (Rad1731) and shows structural similarities with the replication clamp PCNA. T...

The loader was developed on top of the existing Parallel Data Query (PDQ) iterator infrastructure. The loader and converter are iterators. The server treats the load iterator tree just like any other iterator tree and is able to use existing algorithms for parallelization and resource allocation. This also allows the loader functionality to have low level access to SQL functions. The XPS loader...

Clamp loaders load ring-shaped sliding clamps onto DNA where the clamps serve as processivity factors for DNA polymerases. In the first stage of clamp loading, clamp loaders bind and stabilize clamps in an open conformation, and in the second stage, clamp loaders place the open clamps around DNA so that the clamps encircle DNA. Here, the mechanism of the initial clamp opening stage is investiga...

Abstract The large surface area of bunker silos imposes challenges with heating caused by plant respiration during initial ensiling. This study aimed to explore if application a formic- and propionic acid-based additive would improve grass silage quality, reduce losses, increase aerobic stability in silos. At each three harvests, every second tractor load was filled either untreated or acid tre...
