Abstract:

Abstract A simple dynamic tester is proposed, in which a disk of rubber is subjected to a rotating tilting deformation. In one arrangement, the rubber disk rests on a horizontal base and a light steel plate rests on its upper surface. A circular groove in the upper surface of the plate is centered on the axis of the rubber disk. An off-center vertical load is then applied to the rubber disk via a steel ball running in the circular groove. As the ball rolls round the groove, driven by friction with a rotating countersurface, the rubber disk undergoes a rotating off-center compression - a tiltin

The centripetal tilting moments acting on the slipper-pad increase with speed and as a consequence can lead to contact between the slipper and the swashplate at high speed.

Eugene O' Neill, an American playwright was born into a troubled and an upset family on October 16, 1888. Eugene O’ Neill had a quite precarious, wobbly and uneven adolescence as his elder brother was an affirmed alcoholic whereas his mom was a drug addict. This research paper analyzes the alienation, dilemma and the futile struggle of man in the quest of his identity. O'Neill followed the course of a superior and advanced writer looking for a profound focus in the entirety of his significant works. His perspective on humankind in his dramatizations is basically sad and heartbreaking. The auth

Abstract:

Urm1 (ubiquitin related modifier 1) is a molecular fossil in the class of ubiquitin-like proteins (UBLs). It encompasses characteristics of classical UBLs, such as ubiquitin or SUMO (small ubiquitin-related modifier), but also of bacterial sulfur-carrier proteins (SCP). Since its main function is to modify tRNA, Urm1 acts in a non-canonical manner. Uba4, the activating enzyme of Urm1, contains two domains: a classical E1-like domain (AD), which activates Urm1, and a rhodanese homology domain (RHD). This sulfurtransferase domain catalyzes the formation of a C-terminal thiocarboxylate on Urm1. T

Abstract:

ABSTRACT Infrared interferometry is a new frontier for precision ground-based observing, with new instrumentation achieving milliarcsecond (mas) spatial resolutions for faint sources, along with astrometry on the order of 10 microarcseconds (μas). This technique has already led to breakthroughs in the observations of the supermassive black hole at the Galactic centre and its orbiting stars, active galactic nucleus, and exo-planets, and can be employed for studying X-ray binaries (XRBs), microquasars in particular. Beyond constraining the orbital parameters of the system using the centroid wobb

Abstract. The basic Whipple-Carvallo bicycle model for the study of stability takes into account only geometric and mass properties. Analytical bicycle models of increasing complexity are now available, they consider frame compliance, tire properties, and rider posture. From the point of view of the designer, it is important to know if geometric and mass properties affect the stability of an actual bicycle as they affect the stability of a simple bicycle model. This paper addresses this problem in a numeric way by evaluating stability indices from the real parts of the eigenvalues of the bicyc

Abstract:

Detecting and confirming terrestrial planets is incredibly difficult due to their tiny size and mass relative to Sun-like host stars. However, recent instrumental advancements are making the detection of Earth-like exoplanets technologically feasible. For example, Kepler and TESS photometric precision means we can identify Earth-sized candidates (and PLATO in the future will add many long-period candidates to the list), while spectrographs such as ESPRESSO and EXPRES (with an aimed radial velocity precision [RV] near 10 cm s − 1 ) mean we will soon reach the instrumental precision required to

In decerebrate cats, we have studied the response of neurons in the L3-L6 segments of the spinal cord to stimulation of neck and vestibular receptors. Neck receptors were stimulated by head rotation in labyrinthectomized cats or by body rotation with the head fixed in labyrinth-intact cats. Vestibular receptors were stimulated by whole-body tilt in the latter preparation. Most neurons were located outside the motoneuron nuclei and were arbitrarily classified as interneurons. Combinations of roll and pitch stimuli at frequencies of 0.1 or 0.05 Hz were used to determine the horizontal component

Abstract The increase in natural gas consumption by the general public and industry development, in particular the petrochemical and chemical industries, has made increasing the world interest in using gas replacement for natural gas, both as mixtures of flammable gases and gas mixtures as LPG with air (SNG - Synthetic Natural Gas). Economic analysis in many cases prove that to ensure interchangeability of gas would cost less than the increase in pipeline capacity to deliver the same quantity of natural gas. In addition, SNG systems and installations, could be considered as investments to impr

Abstract From the outset cinema was metropolitan. Producers needed access to financing, pools of talent, specialized equipment, and laboratories that one could only find in urban centers. In certain cinema-cities (Berlin, Paris, Buenos Aires, Mumbai, Taipei, etc.) reside ambitious writers, producers, and filmmakers who were driven to outdo, or modify, or simply copy what they saw, employing their own culture’s raw material. Thus, the Jameson-Moretti law applies: local content, pertinent to each nation, was poured into forms that were adopted, with strategic alterations, from Hollywood. Where a

This experimental work describes the operation of a wobble-plate-type fuel pump for the stable supply of dimethyl ether (DME) fuel and evaluates its application possibility in a compression ignition engine. To achieve this, different types of flow control valves (normally open and normally closed types) were installed on the wobble-plate-type fuel pump. At the same time, the variations in fuel flow rate, torque, and temperature variation in the main parts of the pump were investigated under various operating conditions using a pump performance test system.

Abstract:

The drag torque caused by the viscous shear in open multiplate wet clutches has been studied in most available literature whose focus is placed on low circumferential speed. However, the drag torque increases drastically in the high circumferential speed range. The underlying physical principles and the influencing factors of the drag torque at high speed are still indeterminate. The present study aims to experimentally investigate the characteristics of the wobbling vibrations of plates and to characterize the effects of average clearance, flow rate of lubricant, shifting condition, and the n
