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.
