The Pediatric Functional Evaluation Measure (PFEM) is a comprehensive tool to measure the functional capabilities and performance in children from the ages of 6 months to 6 years.
Background
Assessment of the functional limitations is important to determine the severity of disability in developmental delays and to evaluate the benefit of rehabilitation program. In India, one of the many challenges in assessing the effectiveness of therapies has been the paucity of validated measures of function.
Methods
The Pediatric Functional Evaluation Measure evaluates the functional abilities of children under three domains: Physical Function Domain, Mental Function Domain, and Social & Emotional Function Domain. Pooling of questions was done and content validity of the PFEM was examined using a panel of 35 experts. A pilot study was conducted on 110 normal children and 49 children with cerebral palsy.
Results
The content validity for the physical domain, mental domain and socio-emotional domain are 100%, 100%&98.7% respectively. The mean score for inter-rater reliability is .869. The mean values of the normal children in all the three domains are 69.42 which are far higher than the mean value of the children with cerebral palsy (14.054).
Conclusion
These results indicate that the Pediatric Functional Evaluation Measure has a high degree of reliability and validity and also support the notion that the PFEM can be used to assess the functional abilities in children with cerebral palsy.

The interest of realizing cryogenic treatment on various materials has been increased recently. The dimensional stability of Shallow Cryogenic Treated (SCT) and Deep Cryogenic Treated (DCT) AISI 440C bearing steel compassion with Conventionally Heat Treated (CHT) have been investigated in this paper. Thermo mechanical analysis is carried out using a dilatometer. The temperature of the CHT, SCT and DCT specimens were increased upto 810 oC (1083k) with a constant rate of 5oC/min from atmospheric temperature. By using Linear Variable Differential Transformer (LVDT) the change in length of the specimens during the experiment is measured. By using these data, Coefficient of Linear Thermal Expansion (α) has been found for all the specimens, and DCT specimen has 8.7% lower than SCT and 14% lower than CHT specimen.Keywords

In order to sustain in present competitive market, on-time delivery, excellent quality and aesthetic are very much essential. The objective of this paper is reducing the cycle time of assembly of automobile door trim panels by implementing various modernized techniques using lean manufacturing concepts. It is evident from the past reports that in the existing system the cycle time is more and it has poor aesthetic. Here a leading automobile company's front door panel assembly is considered and the assembly line is modernized and automated to reduce the cycle time and to improve the aesthetic. The outcome of this paper leads to substantial reduction in cycle time, reduced cost of maintenance, reduced defects, better utilization of machines and man power. Statistical quality control is carried out on the new method of welding joints. The result shows that the process is under control. Also, the proposed system is validated for its increased productivity and for return on investment (ROI). It has been proved and validated by an empirical relation. The improved return on investment (ROI) and productivity shows the method of performing welding is feasible.Keywords

Metal matrix composite (MMC) focuses primarily on improved specific strength, high temperature and wear resistance application. From the collected literature it is found that, metal matrix composites are under serious consideration as potential candidate materials and it is mainly used to replace conventional materials in aerospace and automotive applications. So, the MMC are highly used in automotive and space applications. And the Aluminium Matrix Composite is a material with two constituent parts, one being a metal, and other being reinforcement. The aluminium matrix can be strengthened by reinforcing with hard ceramic particles like SiC, Al2O3, B4C etc. In this project, aluminium 6061 alloy is chosen as one of constituent parts, which has good mechanical properties and exhibits good weldability. The mechanical properties like tensile strength and Hardness can be increased by reinforcing 6061Al matrix with Boron Carbide (B4C) and Silicon carbide (SiC) particles. In this project, the fabrication of aluminium 6061 with boron carbide and aluminium 6061 with silicon carbide is done by stir casting process, which is a liquid state material fabrication and cost effective method. Then, the samples are tested for mechanical properties like tensile, hardness, impact, flexural. Finally the Scanning Electron Microscope (SEM) analysis is done, which helps to study topography of composites and it produces images of a sample by scanning it with a focused beam of electrons.Keywords

The main objective of this investigation was to evaluate physical, mechanical, morphological and water absorption properties of polypropylene filled with wood flour as filler. New materials based on wood have the advantage that their properties can be engineered so as to correspond to user demands. The properties which can be engineered are those relating both to their utilisation and machining, in particular - the tensile strength, elongation at break, modulus of elasticity and impact resistance. The composites with different wood flour content (10%, 15% and 20%) and polypropylene (PP) were mixed by twin screw extruder and then the composites were manufactured by injection moulding method. Based on the findings in this work, the water absorption and thickness swelling of the composites increased with increasing with amount of the wood flour. Furthermore, both flexural and tensile modulus increased, while both flexural and tensile strength decreased with increasing wood flour contents. Morphological examination is carried out on the fractured surfaces by scanning electron microscopy (SEM), in order to investigate the variation of the measured mechanical properties, revealed presence of micro voids resulting from weak filler-matrix interfacial adhesion.Keywords

The Composite materials have found widespread applications in various fields of engineering such as aerospace, marine, automobile and mechanical applications. Polypropylene is most widely used polymer matrix composite (PMC) due to its unique strength and hardness. In sports application like golf shaft which is subjected to various deflection and torsion loads so that ordinary steel golf shaft is replaced to polypropylene plastics which may help the player for more comfort due to its weight reduction. The Composite structure of golf shaft made of polypropylene plastics is modeled and mechanical behavior is experimentally calculated. Experimentally deflection is measured by hanging a mass on the tip with the butt fixed. The degree of torsion is measured by applying the twisting moment, to the tip. The frequency of vibration is measured by adding a mass to the tip of a shaft and shaking it.Finite element results for deflection and torsion give satisfactory results with the experimental data. These results will be useful in designing polypropylene and sheet rolled golf shaft.Keywords

Friction stir welding (FSW) is a new innovative solid state joining technique for joining similar and dissimilar metal which has been used in aerospace, rail, automotive and marine industries. This paper to optimized the effect of the tool shape and welding parameter on 6.35mm thick 7075- T651 aluminium plates. The process parameters are optimized by using the ANOVA technique based on L9 orthogonal array. Experiments have been conducted based on three process parameters, namely, the tool rotation rate (rpm), welding speed and axial force at three different levels. Impact Strength has been predicted for the optimum welding parameters and their percentage of contribution in producing a better joint is calculated, by applying the effect of the signal-to-noise ratio and analysis of variance. The results indicate that the rotation rate (rpm), welding speed and axial force are the significant parameters in deciding the Impact Strength of the joint.Keywords
