Authors Imran Rashid and Soren Kenner have sparked an international debate by revealing the "mind hacks" Facebook, Apple, Google, and Instagram use to get you and your children hooked on their products. In Offline, they deliver an eye-opening research-based journey into the world of tech giants, smartphones, social engineering, and subconscious manipulation. This provocative work shows you how digital devices change individuals and communities for better and worse. A must-read if you or your kids use smartphones or tablets and spend time browsing social networks, playing online games or even just browsing sites with news and entertainment. Learn how to recognize 'mind hacks' and avoid the potentially disastrous side-effects of digital pollution. Unplug from the matrix. Learn digital habits that work for you.

Thought the tone can be a bit New Agey, The scientific approach and practical hands-on program that helps creative writers and scientific application unpack the reasons for their creative block and to overcome on the issues. Seven years ago, I found children were suffering in abdominal pain after the use of milk powder and doctor diagnosed enteritis at that time as a student i programed to work out for the trouble shooting. Returning to it now, I found that my impressions had not changed, and that the process still worked.

Pakistan is facing severe natural gas crisis and all industries are suffering. Hence all efforts should be made to save natural gas from domestic use. The conventional radial flow natural gas stove burners have low thermal performance because of high convective and radiation heat losses. Swirl flow stoves have comparatively high thermal efficiency. The shape of vessel has significant effect on the performance of stoves. A swirl stove with two heating vessels (a pan and a pot) was used for experiments. Three different flame covering draft tubes were tested i.e. Ceramic mould, Aluminum draft tube and polished steel draft tube. Thermal efficiency was checked by heating water from 30 C to 80 C and determining consumption of natural gas. Ceramic mould increases thermal efficiency of swirl stove from 36 to 39.1%. The aluminum foil with ceramic mould leads to an improvement of 45.1%. Aluminum draft tube, polished steel draft tube and ceramic mould wrapped with aluminum foil showed 2.6, 3.8 and 5.6 % increase in thermal efficiency respectively. The work is useful for designing modified burners and stoves to conserve natural gas.

The Chemical plants, particularly those manufacturing urea are amongst the most complex plants in the chemical process industry. The severe operating conditions affect the safety of equipment, personnel involved and the environment. Different occurred accidents such as Port Neal Nitrogen Fertilizer (Dec 1994), Toulouse Fertilizer complex (Sept 2001) and Coffeyville Fertilizer Plant (Oct 2010) stresses to conduct hazard studies in fertilizer plants. Urea manufacturing process is described for understanding before conducting HAZOP studies. PHA is discussed including its basics, requirements, and procedures along with techniques (HAZOP, WHAT-IF, Check List, and FMEA). The objective of this book is the identification of major malfunctions in urea synthesis section, development of systematic procedure for risk potential assessment, to identify the weak points for process improvement, to rank the potential risk scenarios and to estimate the Quantitative Risk for the worst case scenario using ALOHA software. The book will be useful for students and professionals for understanding hazard analysis techniques and its real implementation in chemical process industries.
