In order to enhance the quality of electricity in microgrids powered by renewable energy, this study introduces a three-phase Active Power Conditioner. The six IGBT bridge is managed three hysteresis controllers. Disturbances microgrid, which fragile electrical grid, can be crucial. Conditioner (APC), described paper, serves as between microgrid's AC bus and energy sources. implementation an up...

Air conditioner merupakan perangkat elektronik untuk mengatur suhu suatu ruangan yang dikendalikan dengan menggunakan remote control dari jarak dekat. dinyalakan ketika sedang digunakan, sebaliknya air dimatikan tidak digunakan. Untuk menyalakan maupun mematikan maka pengurus kerumahtanggaan musti berada dalam dekat tersebut. Padahal ada saatnya dimana namun menyala padahal Peneliti mengatasi k...

STUDY DESIGN Prospective experimental study. PURPOSE To evaluate bacterial contamination during surgery. OVERVIEW OF LITERATURE The participants of surgery and ventilation system have been known as the most significant sources of contamination. METHODS Two pairs of air culture blood agar plate for G(+) bacteria and MacConkey agar plate for G(-) bacteria were placed at 3 different location...

In this paper, a control method for inverter air conditioner is presented, which is to use evaporating pressure as middle-target via fuzzy method. It is a method to control in cascade stage. Simulation results of performance of the control method, comparing with a traditional fuzzy method, were obtained.

Most of the 24 known Chitinophaga species were originally isolated from soils. We report the draft genome sequence of a putatively novel Chitinophaga sp. from a biofilm in an air conditioner condensate pipe. The genome comprises 7,661,303 bp in one scaffold, 5,694 predicted protein-coding sequences, and a G+C content of 47.6%.

This paper discusses the results of tests done to investigate performance a thermoelectric air conditioner (TEAC). The TEAC is composed twelve modules (TEMs). TEMs were fixed rectangular fin heat sinks on both their hot and cold sides. With an increased input<em> </em>voltage, cooling capacity increased. At 6 V input voltage flow, suitable condition occurred. rate flow was 0.48 kg/m...

The aim of this study was to determine whether there was any difference in the degree of enamel loss at bond-up, debond and enamel clean-up when two different adhesive systems were tested and with four different methods of enamel clean-up. The adhesive systems were 37 per cent o-phosphoric acid with Transbond XT (group 1) and 10 per cent poly(acrylic acid) conditioner with Fuji Ortho LC (group ...

Purpose: The purpose of the present study was to investigate the bond strength of an indirect composite material to a magnetic stainless steel alloy. Materials and Methods: The surfaces of machined magnetic stainless steel alloy specimens were abraded with 600-grit silicon carbide paper and then grouped according to the type of surface treatment given: 1) without preparation, 2) tribochemical s...
