Development of human growth hormones
Biotechnology plays a
significant role in today’s lives especially in
the scope of medical biotechnology which
can be identified as red biotechnology to
cure many diseases and for many other
purposes after the modifications of the
biotechnology has been made for this
modern world. Growth hormone deficiency
is one the diseases that has been cured by
the development of human growth hormone
by DNA recombinant technologies or
efficient fermentation. Human growth
hormone provides important benefits such
as maintaining body and bone mass,
promoting longitudinal growth and
lipolysis, strengthening muscles,
enhancing weight loss and erectile
dysfunction, and ensuring a well�functioning cardiovascular system.
Development of human growth hormones
has given good effects to the society, which
is made of the consumers, people under the
production team, businessmen, economics
and the countries. Thus, the development of
human growth is an effective and
successful idea which is very important for
developing our lifestyle
Feasibility study of air catcher for natural ventilation application
Ventilation is the process of supplying fresh air and removing stale air. Natural ventilation is an effective method to save energy required to condition building and to improve indoor air quality. It is widely recognized as contributing in low energy building design. In present work, five types of low Reynolds number airfoils were used to design air catchers with three angles of attack and four different diameters. SolidWorks was used to build the geometries and Computational Fluid Dynamics (CFD) was used to simulate the buoyancy driven natural ventilation. Mesh dependency test has been done for three sizes of mesh and result was validated by comparing the numerical result with experimental result for NACA2415 airfoil. Sixty cases were studied by considering five types of airfoils air catchers, three angles of attack ( 0°, 10° and 20 °) with four diameters ( 0.75Cax, 1Cax, 2.5Cax and 3Cax ) for each type by using CFX ANSYS with k-ε turbulence model. All the configurations show improvement on the effective mass flow rate. Nominal and effective mass flow rates and improvement factor were calculated for each case. It is observed that the improving factor increased with angle of attack and decreased with diameter. The results showed that the best improvement factor was found at S1223 air catcher with 112.5 mm diameter and 20° angle of attack. Therefore, the air catcher is feasible for the natural ventilation application

Production of natural food-derived vitamin c from orange juice
Vitamin C is also called
ascorbic acid and ascorbate. Usually,
vitamin C can be found in citrus fruits,
bell peppers, guavas, papayas,
cruciferous vegetables, and tomatoes.
Synthetic vitamin C supplement is also
widely sold in pharmacies. Vitamin C is
needed for normal growth and
development of the human body, and it
also functions as an antioxidant to
provide plants protection from side�effects of light during photosynthesis in
plants. Shortage of vitamin C in humans
may result in scurvy disease. Synthetic
and food-derived vitamin C are
chemically identical, however there is
increasing consumer interest in natural
food-derived vitamin C. This chapter
provides a review of the technology used
to extract vitamin C from orange juice,
treatment of extracted vitamin C, quality
control tests on the food-derived vitamin
C, as well as the advantages of using
these technologies to produce food�derived vitamin C
