In this present work, the effect of input parameters viz. grinding wheel speed, work-piece speed, abrasive grain size, depth of cut, concentration of cutting fluid, and number of passes has been found on the out-ofroundness of cylindrical grinded AISI 4140 steel. Out-of-roundness is of great importance in case of shafts, axles, pistons, piston pins, crankshafts, roller bearings as out of roundn...

To facilitate the manufacturing of a ball-end mill, this paper presents an algorithm for ball-end mills gashing by using a five-axis computer numerical control (CNC) grinding machine. In this study, the normal helix models are proposed. Then, based on the cutting edge geometric model and the machining mode of the five-axis computer numerical control (CNC) grinding machine, the coordinate of the...

The objective of this study was to determine whether short exposure to pulsed electromagnetic fields (PEMF) accelerates bone repair and peri-implant bone formation in a rat tibial model at different times. Sixty Wistar rats were employed. Sterile custom fabricated commercially pure cylinder threaded titanium implants were placed in the right tibial crest, and an osteotomy was performed in the l...

Longissimus dorsi muscle (LD) proteomics provides a novel opportunity to reveal the molecular mechanism behind intramuscular fat deposition. Unfortunately, the vast amounts of lipids and nucleic acids in this tissue hampered LD proteomics analysis. Trichloroacetic acid (TCA)/acetone precipitation is a widely used method to remove contaminants from protein samples. However, the high speed centri...

It has been generally accepted that calcium intake prevents bone loss, and frequent fracture resulted from osteoporosis. However, it is still elusive as to how effective sole calcium intake is in preventing or attenuating the severity of osteoporosis. Here, we demonstrate the effects of eggshell-casein phosphopeptide (ES-CPP), and compared these effects those of calcium supplement, for restorin...

The objective of this study was to investigate the effects of saffron as a natural sunscreen and moisturizer. The pollens of the saffron were dried and powdered in a grinder. The experimental formulations included a homosalate (8%) lotion reference, lotions with 2, 4 and 8% of grinded saffron, and the control lotion base without saffron. The lotions containing saffron were prepared like homosal...

Herbal prescriptions have been recognized as potentially valid by the scientific medical establishment, and their use has been increasing. Sida tiagii Bhandari (Sida pakistanica; family-Malvaceae), a native species of the Indian and Pakistan desert area, popularly known as "Kharenti" in India; is used as a folk medicine. In the present study, various fruit extracts of Sida tiagii were investiga...

Mussel shell is a type of waste that generated abundantly. However, the presence chemical components such as calcium (CaCO3) in mussel shells has shown its potential filler materials concrete designing. Therefore, this paper presents experimental result for physical and mechanical properties containing 1%, 2%, 3% 4% Shell Powder (MSP) additional material under 2.73% sodium chloride solution. Th...

In this study, we report one-pot, single step synthesis of silver nanoparticles stabilized by using arbutin. The concentration reducing agent (NaBH4) used in the preparation was kept at double, and arbutin as a stabilizing agent. confirmation prepared done color change UV-Vis surface plasmon resonance peak 435 nm spectrum. Size dispersion carried out Dynamic Light Scattering (DLS) charge on nan...

Contamination of effluents with chemicals is a serious problem that impacts human health. Methylene blue cationic dye found frequently in industrial and urban sewages. In this work, dried grinded seeds peels nance were used as biosorbents aqueous solutions at pH 7 10 (simulating textile effluents) finding Langmuir Freundlich isotherms adequately described the sorption. Adsorption efficiencies l...
