The present work is aimed at exploring the applicability of theory critical distances (TCD) to plain and notch fatigue prognosis ductile cast iron GJS600. Particular attention paid investigating how defectiveness influences material length. It was found that damage triggered by microshrinkage porosity in samples graphite nodules notched samples. This evidence makes cumbersome TCD, which postula...

Some zones of freezing curtains subway contact channels are subjected to compression and tension. Thus, understanding the mechanical properties relationship between compressive flexural strengths frozen soil is crucial. In this regard, study considered sandy from Fuzhou as an example perform uniaxial three-point strength tests under different moisture content curing conditions. The results show...

PURPOSE To evaluate the strength and pattern of the relationship between visual field (VF) sensitivity and retinal nerve fiber layer (RNFL) thickness measurements by scanning laser polarimetry (SLP). METHODS Fifty-four eyes of 54 normal subjects (age, 42 +/- 15 years; VF mean deviation [MD], -0.69 +/- 1.01 dB) and 51 eyes of 51 glaucoma patients (age, 66 +/- 14 years; VF MD, -6.92 +/- 5.43 dB...

Precipitation behavior and the quenching sensitivity of a spray deposited Al-Zn-Mg-Cu-Zr alloy during isothermal heat treatment have been studied systematically. Results demonstrate that both the hardness and the ultimate tensile strength of the studied alloy decreased with the isothermal treatment time at certain temperatures. More notably, the hardness decreases rapidly after the isothermal h...

Acute flaccid paralysis (AFP) is a clinical syndrome characterized by rapid onset of weakness, including (less frequently) weakness of the muscles of respiration and swallowing, progressing to maximum severity within several days to weeks. The term "flaccid" indicates the absence of spasticity or other signs of disordered central nervous system motor tracts such as hyperreflexia, clonus, or ext...

Corresponding to the pronounced amplitude asymmetry for the central Pacific (CP) and eastern Pacific (EP) types of El Niño, an asymmetry in the strength of the Bjerknes positive feedback is found between these two types of El Niño, which is manifested as a weaker relationship between the zonal wind anomaly and the zonal gradient of sea surface temperature (SST) anomaly in the CP El Niño. The st...

This paper presents algorithms for encryption and decryption developed using pseudo random number generator (PRNG) and non-Linear functions. PRNG used in the work are matlab random number generator (RNG) and Linear congruential generator (LCG). The developed algorithms are named according to PRNG used in it. State of PRNG is considered as secret key of the cipher. The encryption schemes have be...
