We investigated how physiologically observed forward suppression interacts with stimulus frequency in neuronal responses in the guinea pig auditory cortex. The temporal order and frequency proximity of sounds influence both their perception and neuronal responses. Psychophysically, preceding sounds (conditioners) can make successive sounds (probes) harder to hear. These effects are larger when ...

Miscanthus is emerging as a promising feedstock for domestic biofuel production. However, inefficiencies of the machinery that is used for harvesting bioenergy crops such as miscanthus currently prohibit commercial production. The performance of a mower-conditioner used to harvest miscanthus was evaluated, and modifications to the disk head were made to allow the machine to operate more efficie...

Continuous innovations and modernization has greatly contributed to the development in automobile industry. Automobile has become a huge luxury for everyone in all the countries. All modern automobiles like cars are equipped with air conditioner and heater units. An air conditioner alters the properties of air (temperature and humidity) to more comfortable conditions in building, house or autom...

This paper presents a new transformation scheme for the control of active power-line conditioner. An active powerline conditioner is a power electronic device which is designed to su.ppress the power-line distortions caused by the non-linear loads. Currently, the method of instantaneous power transformation is the most popular one for the active power-line conditioning control. This method uses...

An UPQC (Unified Power Quality Conditioner) is anequipment composed by two active conditioners operating in a combined way. One of the active conditioners is connected in series with the electrical power system, allowing the compensation of problems in the system voltages. The other active conditioner is connected in parallel with the electrical system, and allows the compensation of current ha...

The aim of this in vitro study was to evaluate by scanning electron microscopy the morphological aspects of the enamel of primary teeth after etching with 36% phosphoric acid or a non-rinse conditioner. Ten naturally exfoliated anterior primary teeth were selected. The samples were subjected to prophylaxis with pumice paste and water using a low-speed hand piece. Etching was done on the buccal ...

Here we develop a general purpose pre/post conditioner T, to solve an ill-posed system of linear equations, Ax = b. The conditioner T is obtained in the course of the solution of the Laplace equation, through a boundary-collocation Trefftz method, leading to: Ty = x, where y is the vector of coefficients in the Trefftz expansion, and x is the boundary data at the discrete points on a unit circl...

Aim: The aim of the study was to evaluate the surface conditioned dentin and its effect on microleakage of metal copings luted with glass-ionomer cement. Objectives: (1) To evaluate the morphology of unconditioned and conditioned dentin, (2) to evaluate the elemental composition of unconditioned and conditioned dentin, (3) to evaluate and compare the microleakage of metal copings luted with gla...

Background: A neem-based conditioner lotion (ONC) used against head lice was previously tested clinically and shown to be relatively ineffective. To improve the activity against lice and their eggs, it was reformulated into a silicone vehicle (NNC) as part of a project to improve pediculicidal medical devices. An ultrasound nit comb was also developed to be used in conjunction with the neem lot...

Abstract: In recent years, as part of the remarkable development of electronic techniques, electronic control has been applied to various systems. Many sensors and actuators have been implemented into those systems, and energy efficiency and performance have been greatly improved. However, these systems have been complicated, and much time has been required to develop system controllers. In thi...
