Modeling of the RadA family mechanism is crucial to understanding the DNA SOS repair process. In a 2007 report, the archaeal RadA proteins function as rotary motors (linker region: I71-K88) such as shown in Figure 1. Molecular simulations approaches help to shed further light onto this phenomenon. We find 11 rotary residues (R72, T75-K81, M84, V86 and K87) and five zero rotary residues (I71, K7...

The effect of the Superpave defined restricted zone on HMA rutting performance was evaluated. One gradation that violated the restricted zone (TRZ) and two gradations that did not violate the restricted zone (BRZ and ARZ) were evaluated. Mixes evaluated represented a range of maximum aggregate sizes (MAS), design traffic levels, and aggregate types. Three laboratory tests, Asphalt Pavement Anal...

This clinical report introduces a method for safe retrieval of a broken implant abutment screw. A reverse-tapping rotary instrument has been introduced in the market and is widely used to retrieve broken screws; however, it is difficult to use the rotary instrument unless an access hole for engagement of the rotary instrument is positioned directly on the center of the top of the broken screw r...

Many catfish cultivators in Indonesia have failed due to lack of attention the quality water used aquaculture ponds. Water is very influential on farming system with biofloc technology, has most important role for survival catfish. This research periodically measures level turbidity and pH water, then readings from sensor will be processed by Arduino Uno which displayed LCD. In addition, this t...

introduction: root fracture is not an instant phenomenon but a result of gradual development of tiny craze lines in tooth structure. recent studies have shown that canal instrumentation has the potential to cause dentinal cracks. the purpose of this study was to evaluate and compare the formation of dentinal cracks caused by protaper rotary system to hand instrumentation. materials and methods:...

A multi-channel continuous-flow ana]yzer equipped with biosensing deyices was deyeloped for multicomponent measurement and its use in automating routine analysis was evaluated. Biosensing was achieyed by the aid of an immobilized enzyme reactor insta]led in the channel, and the channe] switching process for the sensing of a different compound was made by using a column-switching rotary valve. A...

A rotary reactor and a fluidized bed reactor (both laboratory-scale and operated in batch mode) are used for the treatment of granulates containing SSA and CaCl ) and treating this mixture (possible after granulation) in a rotary kiln at 1000±100°C leads to the formation of volatile heavy metal compounds which evaporate and to Pphases with a high bio-availability. Due to economical and ecologic...

In this project a servo (position) controller that is able to receive commands via a Controller Area Network (CAN) is presented. Additionally, the board was developed to be as generally usable as possible in the sense that if the DC motor to be controlled does not have a rotary encoder, then a contactless magnetic rotary encoder (CMRE) module can be plugged into the board (via two SIL connector...
