two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

Friction stir processing (FSP) was used to modify the microstructure and improve mechanical properties corrosion resistance of an Mg–Al–Ca alloy. The results demonstrated that, after FSP, grain size alloy decreased from 13.3 6.7 μm. Meanwhile, Al8Mn5 phase broken dispersed, its amount increased. yield strength ultimate tensile were increased by 17.0% 10.1%, respectively, due combination fine gr...

Introduction: Micrometeorites (MMs) are large (>25 µm) interplanetary dust particles that survive atmospheric entry to be recovered from the Earth's surface. Amongst those particles that escaped significant heating during atmospheric entry two groups have been identified [1]: (i) fine-grained MMs (fgMMs), which are similar to the fine-grained matrices of hy-drated carbonaceous chondrites (CCs),...

Fluids are inferred to play a major role in the deformation and recrystallization of many minerals (e.g. quartz, olivine, halite, feldspar). In this study, we sought to identify the effect of fluids on grain boundary morphology and recrystallization processes in marble mylonites during shear zone evolution. We compared the chemistry, microstructure and mesostructure of calcite marble mylonites ...

Zn levels in rice are essential for maintaining consumer health. However, deficient plants can reduce of grains and the ability to express their genetic potentials. This study examines use cow manure enriched with heptahydrate on increasing broken skin rice. The experiment was arranged a randomized single factor group design seven dose treatment, namely: 0; 2.5; 5, 7.5, 10, 12.5, 15 tons ha-1, ...

different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...
