Riboswitches are mRNA-based modules that control gene expression through direct RNA-ligand interactions.[1) In most cases, the regulatory ligands are metabolites that act on their own biosynthesis genes through feedback regulation. Since their discovery by Breaker and co-workers in 2002, nucleobases, amino acids, cofactors, as well as the amino sugar glucosamine-6-phosphate have been described ...

In this paper, an analytical solution for computing the plastic & linear plastic stresses and critical angular velocity in a FGM hollow & solid rotating disk is developed. It has been assumed that the modulus of elasticity and yield strength were varying through thickness of the FGM material according to a power law relationship. The Poisson's ratio were considered constant throughout the thick...

A cratered asteroid acts somewhat like a retroflector, sending light and infrared radiation back toward the Sun, while thermal inertia in a rotating asteroid causes the infrared radiation to peak over the “afternoon” part. In this paper a rotating, cratered asteroid model is described, and used to generate infrared fluxes which are then interpreted using the Near Earth Asteroid Thermal Model (N...

Cancer can significantly have ruining effects on very high of human beings, social, and economic condition. Bladder cancer has been reported as one of the most common cancers and the incidence rates of this cancer is increasing across the world. Cystectomy is a surgery to remove the urinary bladder. In the present study a part of the ileum is used instead of bladder. This study deals with mucos...

The purpose of the present study was to compare the Braun/Oral-B Plak Control (D7) and Sonicare (S) in their plaque-removing efficacy. For this study, 35 university students (non-dental) were selected. This was a 2-part study. Prior to each appointment, all subjects were asked to abstain from all oral hygiene procedures for at least 24 h. In Part 1, the efficacy of the toothbrush was studied wh...

In the Randall-Sundrum two-brane model (RS1), a Kerr black hole on the brane can be naturally identified with a section of rotating black string. To estimate KaluzaKlein (KK) corrections on gravitational waves emitted by perturbed rotating black strings, we give the effective Teukolsky equation on the brane which is separable equation and hence numerically manageable. In this process, we derive...

One of the reasons subsoil liquefaction are cyclical loads induced from earthquake. It generally take in when there is a loose saturated granular soil. Loose, sand and silty have highest probability liquefaction. Most places prone to this event that close water source, namely river or bay area. Mataram city located on west coast Lombok Island. acts as capital economic powerhouse region. The 201...

BACKGROUND/AIM Synovial chondromatosis associated, intra-articular loose bodies are usually small in size. Giant intra-articular loose bodies are rare. CASE REPORT We present the case of a patient with synovial chondromatosis associated giant intra-articular loose bodies located under the patella and the intercondylar fossa, treated successfully with combined arthroscopic and open excision. ...

This paper presents a novel testbed capable of rotating a target to follow an arbitrary prescribed rotational trajectory, such as the tumbling motion of a satellite undergoing torque-free dynamics. This work is part of a larger research endeavor investigating technology applicable to autonomous rendezvous and docking with a tumbling satellite. This testbed provides unoccluded visibility of the ...
