Successful surgical correction for anomalous origin of the left coronary artery from the pulmonary artery in a 4-year-old child is reported. An aortopulmonary fistula was created and a pericardial baffle was inserted within the pulmonary artery to connect the fistula to the ostium of the left coronary artery. The clinical, haemodynamic, and angiographic features of the anomaly are presented. Th...

In this paper, a metal–insulator–metal (MIM) surface plasmon waveguide structure is proposed and numerically investigated. It composed of square-ring cavity with silver baffle, an isosceles triangle cavity, bus baffle. The results show that the can produce triple Fano resonances be independently tuned by changing structural parameters. detection refractive indexes at different positions in was ...

An Acoustic Window is comprised of a horizontal sliding window at the inner layer, and side-hung window, which can be pushed to open, on one side outer fixed glazing other side. The serves as “baffle” for screening off noise passing through opened when it slid behind window. This baffle-type acoustic proved reduce up 8 dB(A) road traffic gaining popularity in residential developments Hong Kong,...

Windage power loss (WPL) is significant and cannot be neglected in a study on transmission efficiency reducing the energy consumption of high-speed gear. The influence mechanism baffle reduction WPL needs to further studied. Based computational fluid dynamics (CFD) technology, this paper puts stress analyzing axial radial baffles viscous pressure effects with groove structures WPL. numerical ca...

با توجه به تأثیرگذاری افزایش توانایی فضایی دانشجویان بر درک فضاها و احجام، هدف این پژوهش بررسی میزان اثربخشی یکی از دروس پایه کارشناسی بر افزایش توانایی فضایی است. لذا پرسش اساسی این است که آیا تدریس هندسه کاربردی، با شیوۀ مرسوم می<span style="letter-spacing: -0.05pt; font-family: 'ARTUNIV',se...

A baffled arc array (BAA) comprises a circular array of sensors surrounding a cylindrical metal baffle, and beamforming is carried out by processing sensors on an arc centred on beamsteer. It is widely used in sonar for passive underwater surveillance. An important factor that limits the performance of the array at high frequencies is the appearance of grating lobes in the beamformer response. ...

n Contemporary studies indicate that teen pregnancy interferes with young women’s ability to graduate from high school and to enroll in and graduate from college. Conversely, planning, delaying and spacing births appears to help women achieve their education and career goals. Delaying a birth can also reduce the gap in pay that typically exists between working mothers and their childless peers ...
