Practical Troubleshooting of Electrical Equipment and Control Circuits

Practical Troubleshooting of Electrical
Equipment and Control Circuits
Elsevier | ISBN 0 7506 6278 6 | Pdf | 246 pgs | 7 mb

There is a large gap between the theory of electron flow, magnetic fields and that of troubleshooting electrical equipment and control circuits in the plant. In this book, we try to avoid or at least minimize discussions on the theory and instead focus on showing you how to troubleshoot electrical equipment and control circuits. The book helps to increase your knowledge and skills in improving equipment productivity whilst reducing maintenance costs. Reading this book will help you identify, prevent and fix common electrical equipment and control circuits. The focus is ‘outside the box’. The emphasis is on practical issues that go beyond typical electrical theory and focus on providing those that attend with the necessary toolbox of skills in solving electrical problems, ranging from control circuits to motors and variable speed drives.

This book focuses on the main issues of troubleshooting electrical equipment and control circuits of today to enable you to walk onto your plant or facility to troubleshoot and fix problems as quickly as possible. This is not an advanced book but one aimed at the fundamentals of troubleshooting systems. The book is very practical in its approach to troubleshooting and the examples you will be shown are applicable to any facility.

The Art of Writing Reasonable Organic Reaction Mechanisms

The Art of Writing Reasonable Organic Reaction Mechanisms
Robert B. Grossman | ISBN 0-387-95468-6 | Pdf | 371 pgs | 7 mb

The purpose of this book is to help you learn how to draw reasonable mechanisms for organic reactions. A mechanism is a story that we tell to explain how compound A is transformed into compound B under given reaction conditions. Imagine being asked to describe how you travelled from New York to Los Angeles (an overall reaction). You might tell how you traveled through New Jersey to Pennsylvania, across to St. Louis, over to Denver, then through the Southwest to the West Coast (the mechanism). You might include details about the mode of transportation you used (reaction conditions), cities where you stopped for a few days (intermediates), detours you took (side reactions), and your speed at various points along the route (rates). To carry the analogy further, there is more than one way to get from New York to Los Angeles; at the same time, not every story about how you traveled from New York to Los Angeles is believable. Likewise, more than one reasonable mechanism can often be drawn for a reaction, and one of the purposes of this book is to teach you how to distinguish a reasonable mechanism from a whopper.

It is important to learn how to draw reasonable mechanisms for organic reactions because mechanisms are the framework that makes organic chemistry make sense. Understanding and remembering the bewildering array of reactions known to organic chemists would be completely impossible were it not possible to organize them into just a few basic mechanistic types. The ability to formulate mechanistic hypotheses about how organic reactions proceed is also required for the discovery and optimization of new reactions.

The general approach of this book is to familiarize you with the classes and
types of reaction mechanisms that are known and to give you the tools to learn how to draw mechanisms for reactions that you have never seen before.

Taman Etnik

SEBUAH taman dapat menyempurnakan gaya etnik pada arsitektur dan interior rumah. Kehadirannya dapat memperlembut serta memberi nuansa alami, dan menyejukkan mata dan rasa.

Ciri khas taman etnik adalah hadirnya jenis-jenis tanaman eksotik seperti palem, kelapa, pisang-pisangan, kamboja, lotus, dan teratai serta penempatan benda-benda etnik yang tepat di antara tetanaman itu.


Patung-patung etnik sebagai aksen penyambut tamu pada entrance taman yang didisplay di atas pilar-pilar warna kuning memberikan ide segar.


Kehadiran padepokan mungil di antara taman dan kolam renang memberi nuansa yang sangat alami.


Area makan di taman menggunakan perabot kayu yang memperlihatkan lekuk-lekuk dan warna alaminya.



Taman terasa luas dan berkarakter dengan kehadiran paduan jenis tanaman-tanaman
tropis, jalan setapak dari batuan alami, dan patung atau ornamen taman lainnya.


Detail pot etnik natural hadir sebagai ornamen taman yang menarik.

Tips
PILIH TANAMAN YANG BANYAK DITEMUKAN DI HALAMAN-HALAMAN RUMAH DAERAH TROPIS SEPERTI PISANG-PISANGAN, PALEM, KAMBOJA, DAN TERATAI. TATA DENGAN GAYA TAMAN YANG MEMBIARKAN TANAMAN SEOLAH-OLAH TUMBUH TAK BERATURAN.

Pengolahan pintu masuk ke area taman dengan pemakaian pintu-pintu regol kayu antik membuat tiang batu alam terlihat sangat natural dan unik.

Tips
LETAKKAN BENDA-BENDA ETNIK YANG TEPAT SEPERTI POT-POT TERAKOTA, PANCURAN AIR DARI BAMBU, DAN PATUNG-PATUNG BATU.

LETAKKAN LAMPU-LAMPU SOROT DADA SUDUT-SUDUT TAMAN SEHINGGA KEEKSOTISAN TAMAN JUGA DAPAT DINIKMATI DI MALAM HARI.

BAU-BAUAN DAPAT MEMBUAT SUATU SUASANA BERKESAN KUAT. JADI, HADIRKAN TANAMAN-TANAMAN TROPIS SEPERTI MELATI, KAMBOJA, KENANGA, DAN CEMPAKA, YANG BUNGA ATAU DAUNNYA DAPAT MENGHASILKAN AROMA.

Teras taman yang sengaja ditata menyatu dengan ruang lukis memberi inspirasi lingkungan untuk sang pemilik rumah dalam menuangkan karya lukisnya.
