The present crude oil and natural gas reservoirs around the world have depleted conventional production levels. To continue enhancing productivity for the remaining mature reservoirs, drilling decision-makers could no longer rely on traditional balanced or overbalanced methods of drilling. Derived from conventional air drilling, underbalanced drilling is increasingly necessary to meet today’s energy and drilling needs. While more costly and extreme, underbalanced drilling can minimize pressure within the formation, increase drilling rate of penetration, reduce formation damage and lost circulation, making mature reservoirs once again viable and more productive. To further explain this esse...
Uraian buku ini secara umumnya memuat tentang pikiran-pikiran para Doktor yang telah menyelesaikan studinya di Sekolah Pasca Sarjana UIN Syarif Hidayatullah Jakarta.

This book presents a comprehensive survey of acute heart failure. A series of experts recognized worldwide discuss specific topics so that, together, a wide spectrum of experimental and clinical investigations are covered. Pathophysiologic, diagnostic and therapeutic aspects are included. The present volume will help clinicians deal with the important problem of acute heart failure. It will help provide an up-to-date reference for those involved in cardiology, internal medicine, pediatrics, anesthesia, intensive care and emergency medicine.
The death of George Floyd on May 25, 2020, and the ensuing trial of Derek Chauvin for murder a year later has rubbed raw the bloodiest stain on the United States’ history and its world reputation. The nine minutes and 29 seconds during which Chauvin’s knee crushed the spark of life out of Floyd was not unusual in the history of the United States. Before the U.S. Civil War, slaves were routinely beaten to death for disobeying orders or running away, then often lynched. In roughly two centuries, Blacks have achieved nominal freedom. But, as this book’s opening chapter and expert essays that follow indicate, freedom has been conditional based on inequity of wealth, social, and legal discr...

Capitalizing on the rapid growth and reduced costs of laser systems, laser cladding is gaining momentum, and in some instances replacing conventional techniques of depositing thin films because it can accommodate a great variety of materials, achieve uniform thickness and precise widths of layers, and provide improved resistance to wear and corrosion in the final product. Laser cladding technology also offers a revolutionary layered manufacturing and prototyping technique that can fabricate complex components without intermediate steps. Laser Cladding reviews the parameters, techniques and equipment, process modeling and control, and the physical metallurgy of alloying and solidification dur...
