We travel to India to see the Taj Mahal, Egypt to see Pyramids, Turkey to see Blue Mosque, Italy to see Colosseum, South America in quest of Inca civilization, and so on. But very few travel to Nunavut – A Land of Inuit. Md Abdus Salam – the author, had a chance to travel, live, and work in Arctic Bay – a small Nunavut community, for 12 years. Not many people in the world know about life in Nunavut. Many people in the southern part of Canada have no idea where and what Nunavut is, no question to speak about Arctic Bay, where Salam landed to teach in 2007. As he learned to survive the harsh winters and other challenges unique to the North, the Arctic also provided him amazing experiences, from polar bears to the aurora borealis, snowmobiles, and potable water problems. Used to living in a large community with many amenities, Salam faced some unique predicaments while living and teaching in the land of Inuit. In the North, he learned of Inuit culture, heritage, and hunting practices while learning to live in a land of extremes—including -60C cold, three months of complete darkness in the winter, and 24/7 daylight for three months in the summer. The memoir Highlights Md Abdus Salam’s experiences first as an immigrant teacher and then as a principal in the community of Arctic Bay. Ikpiarjuk: My Challenges Teaching in a Land of Inuit speaks to the experiences of a talented educator’s time spent living and teaching in a place that was utterly unknown to him.
This book covers the basics of DC circuits, AC circuits, three-phase power to understand the basics and controls of electro-hydraulics and electro-pneumatics. This book covers detailed knowledge on the fluid power properties, Bernoulli’s equation, Torricelli’s theorem, viscosity, viscosity index, hydraulic pumps, hydraulic valves, hydraulic motors, pressure control valves, pneumatic systems, pneumatic cylinders, different types of gas laws, valve actuation, relay, magnetic contactor, different types of switches, logic gates, electro-pneumatic control circuits with different options and introduction to PLC. In addition, the detailed technique of Automation Studio software, different types of simulation circuits with hydraulics, pneumatics and electro-pneumatic are included. This book will be an excellent textbook for electromechanical, robotics, mechatronics, electrical control and mechanical students as well as for the professional who practices fluid power systems.
This book provides electrical and electronic engineering undergraduate and graduate students and trainees with practical information on grounding-system parameters, and on different methods for measuring soil resistivity and ground resistance. It also presents some real-world studies, which enhance the learning experience. It discusses electromagnetic field theories to explain ground resistance modeling using different sizes of electrodes. Furthermore it includes CYME GRD software for simulation of soil resistivity and grounding grid design, and considers some fundamental concepts of power systems to clarify other topics related to the grounding system.
This book covers the topic from introductory to advanced levels for undergraduate students of Electrical Power and related fields, and for professionals who need a fundamental grasp of power systems engineering. The book also analyses and simulates selected power circuits using appropriate software, and includes a wealth of worked-out examples and practice problems to enrich readers’ learning experience. In addition, the exercise problems provided can be used in teaching courses.
A four year Electrical and Electronic engineering curriculum normally contains two modules of electromagnetic field theories during the first two years. However, some curricula do not have enough slots to accommodate the two modules. This book, Electromagnetic Field Theories, is designed for Electrical and Electronic engineering undergraduate students to provide fundamental knowledge of electromagnetic fields and waves in a structured manner. A comprehensive fundamental knowledge of electric and magnetic fields is required to understand the working principles of generators, motors and transformers. This knowledge is also necessary to analyze transmission lines, substations, insulator flashover mechanism, transient phenomena, etc. Recently, academics and researches are working for sending electrical power to a remote area by designing a suitable antenna. In this case, the knowledge of electromagnetic fields is considered as important tool.
This book is designed as an introductory course for undergraduate students, in Electrical and Electronic, Mechanical, Mechatronics, Chemical and Petroleum engineering, who need fundamental knowledge of electrical circuits. Worked out examples have been presented after discussing each theory. Practice problems have also been included to enrich the learning experience of the students and professionals. PSpice and Multisim software packages have been included for simulation of different electrical circuit parameters. A number of exercise problems have been included in the book to aid faculty members.
Flight from Wonder reports the findings from an empirical study of 45 Nobel laureates in science from the United States and Europe concerning the creative processes that produce scientific discoveries. To this end, Albert Rothenberg designed an interview procedure to delineate the content and sequences of processes that lead scientists to specific creative achievements. He conducted interviews with Nobel laureates in the fields of medicine, physiology, physics, and chemistry and carried out matching interviews with a control group consisting of twelve accomplished engineers on the faculty of a leading engineering university. Rothenberg's results demonstrate that the Nobel laureates use three distinct cognitive creative processes to achieve key formulations and discoveries; the detailed nature and structure of these findings were reviewed by the Nobel laureates. To predict his findings, Rothenberg engaged with autobiographical accounts and work-in-progress manuscripts pertaining to the creative discoveries of outstanding scientists of the past including Albert Einstein, Charles Darwin, Max Planck, Neils Bohr, Hideki Yukawa, and James Watson. The book will interest students and general readers fascinated by creativity and the development of scientific inquiry and innovation.
This book is the outcome of a field study of 162 suicide cases conducted in two suicide prone Upazilas of Jheneidah District in Bangladesh. The adolescent females and males were found to be the most suicide prone. The major factors that drive the victims to commit suicide were found to be bad relationship between husbands and wives, family quarrels, poverty, suffering from chronic and incurable diseases, etc. In Jheneidah the majority of the suicide victims were young housewives between 16–25 years of age. Unmet dowry demands, the desire of husband to marry for the second time and family quarrels led to torture of young housewives by their husbands and in-laws specially mother-in-laws. Illiteracy, poverty and total economic dependence on husbands or parents appeared to be the major contributory factors behind these suicide cases. It is suggested that the laws against polygamy and dowry system should be strictly enforced and special legal aid should be provided to help the parents of suicide victims. The book also discusses the socio-economic and psychological conditions of suicide victims, the factors which compelled them to commit suicide, methods of committing suicide and the months, timing and place of suicide. A brief description of 19 suicide cases has been given in the book. Some measures for reducing and preventing the incidence of suicide have also been suggested.
The information in this book is meant to find the answers (Truth) to basic questions we have as Human beings. This book is not permissible to print for a commercial purpose other than self-study. I have compiled this book using different resources from the internet in order to conduct the study. Some of the questions mentioned in the book are:- Why I exist? Who am I? Where I came from? Why I am here? Why I have to die? Where I am going? ...
Take a mind blowing journey beyond the furthest stars, from the Big Bang to the end of time. Witness the evolution of complexity, from organic chemistry to the Dinosaurs. Probe the deepest recesses of the human mind in search consciousness itself. It's all here in this dazzling first volume of Henry Kong's history of the Universe.
