Assemble the circuit on a small general-purpose PCB and house in a suitable metallic enclosure with an integrated battery holder and headphone/earphone socket. Fit the on/off switch (S1)‚ volume control (VR1) and power indicator (LED1) on the enclosure. Finally‚ fit the condenser microphone (MIC) on

thrust of this book. The use of accounting information for decision making has been a consistent theme in earlier chapters. In this chapter‚ we focus on specific and common decisions such as accepting or rejecting a one-time-only special order‚ insourcing or outsourcing products or services‚ and replacing or keeping equipment. We place special stress on the importance of distinguishing between relevant and irrelevant financial information when making these decisions. L e a r n i n g Ob j e c

| Microelectronic Pill | | | | | | 1.INTRODUCTION The invention of the transistor enabled the first radio telemetry capsules‚ which utilized simple circuits for in vivo telemetric studies of the gastro-intestinal tract. These units could only transmit from a single sensor channel‚ and were difficult to assemble due to the use of discrete components. The measurement parameters consisted of temperature‚ pH or pressure‚ and the first attempts of conducting real-time noninvasive

OCEAN PLASTICS POLLUTION: A GLOBAL TRAGEDY FOR OUR OCEANS AND SEA LIFE Plastic never goes away. And it’s increasingly finding its way into our oceans and onto our beaches. In the Los Angeles area alone‚ 10 metric tons of plastic fragments — like grocery bags‚ straws and soda bottles — are carried into the Pacific Ocean every day. Today billions of pounds of plastic can be found in swirling convergences making up about 40 percent of the world’s ocean surfaces. Plastics pollution has a direct and
