Raw cocoa beans were used to produce cocoa powder and chocolate samples. The processing steps include fermentation, drying, roasting, milling, pressing and conching. The fermentation time varied from 1to 7days, represented as samples A, B, C, D, E, F and G respectively, in order to monitor the influ[r]
Sorghum commonly is eaten with the hull (the outer layer of the grain), which retains the majority of the nutrients. Sorghum has excellent chemical and physical properties, which make it a grain of good quality for processing different types of products. The nutrient composition of sorghum grain ind[r]
Gadolinium is one of the most broadly studied magnetic refrigerantmaterials. It is ferromagnetic below 292 K to 295 K depending on its purity,generally the cleaner metal orders at a higher temperature, entropy variation isSmag= 4 (J/kg.K) in magnetic field 2 T. The maxim[r]
Influence of substitution of 3d metals for Mn on properties of La0.67Ca0.33Mn0.9 TM0.1O3 (TM = Fe, Co, Ni) compounds was studied. Ferromagnetic – paramagnetic and metals – insulator transitions were significantly affected by Mn-site substitution. However, no observable difference was found in their[r]

In the process of the continuous monitoring of the structure’s state properties such as static and dynamic responses using Global Positioning System (GPS), there are unavoidable errors in the observation data. These GPS errors and measurement noises have their disadvantages in the precise monitoring[r]
