According to statistics, the cracking in castings is rarely caused by a purely mechanical damage or external force, which only counts for 2%, while being dominantly caused by internal stress counted for 98% [1, 2].
Previous study [3] has indicated that the impurities in the steel are the most important factor leading to cracking in the cast steel and have a significant influence on quality and mechanical properties of the steel, thus should be controlled strictly.

Spray Characteristics of Swirl Effervescent Injector in Rocket Application: A Review Zulkifli Abdul Ghaffar1,a, Ahmad Hussein Abdul Hamid2,b and Mohd Syazwan Firdaus Mat Rashid3,c 1,2,3Faculty of Mechanical Engineering, Universiti Teknologi MARA (UiTM), 40450 Shah Alam, Selangor, Malaysia azulkiflighaffar@gmail.com, bhussein@salam.uitm.edu.my, cmohd.syazwan.firdaus@gmail.com Keywords: swirl effervescent, spray cone angle, breakup length, SMD Abstract.
Injector design is a major issue in thrust chamber design since it will greatly affects the liquid rocket performances.
Rahman [3] has stated that the resultant spray characteristics of effervescent atomization could be influenced by several factors such as liquid types, liquid physical properties, operating parameters (GLR, injection pressure), injector internal geometry and gas properties (bubble size, flow regimes).

Cartilage lesions frequently result in pain, swelling, and mechanical symptoms such as locking and catching that substantially reduce the patient’s quality of life [4].
Osteoarthritis (OA), the syndrome of joint pain and dysfunction caused by joint degeneration, affects more people than any other joint disease.
In recent decades numerous studies related to tissue engineering have shown that the combination of cells, bioactive molecules (growth factors, cytokines, and fragments of polymers) and scaffolds (biomaterials) function as an outline for the newly-formed tissue, facilitating interaction, proliferation and tissue differentiation [11].
The efficiency of these multiphase materials is due to the mechanical properties of bioceramics (compressive strength) associated with water-soluble polymers considered good ionic carriers that help in the formation of a new extracellular matrix support[13].
Conclusion The composite of carboxymethylcellulose (CMC) and a bioceramic (biphasic calcium phosphate-BCP) in the form of a hydrogel, under the conditions studied, provided adequate injectable properties and non-toxic response, which demonstrate the potential of the material to be used for repair of articular cartilage.

.% Fe), the Ni-Fe alloys can be used in high technologies due to the large range of their physical properties [3].
The mechanical, corrosion and magnetic properties of Ni-Fe alloys are affected by a number of factors including alloy composition, grain size, internal stress and surface roughness.
In turn, these factors are dependent on deposition conditions such as electrolyte composition, pH, applied current density, temperature and agitation [7].
