The effects of porous medium heterogeneity on methane hydrate formation, water flow through the heterogeneous hydrate-bearing sand, and hydrate dissociation were observed in an experiment using a heterogeneous sand column with prescribed heterogeneities. X-ray computed tomography (CT) was used to monitor saturation changes in water, gas, and hydrate during hydrate formation, water flow, and hyd...

Tumorigenic cell lines were established in culture from three transplantable mouse colonic carcinomas designated CT 26, CT36, and CT 51. The cultured lines were characterized for the retention of the biological characteristics of the parental lines. All three cultured lines retained the ability to form tumors in vivo. Serially transplanted parental lines CT 26 and CT 51 grew at a faster rate th...

This work evaluated the synergistic effect of citronella essential oil (Ct) and montmorillonite (MMT) (called hybrid compound) incorporated in Poly(lactic acid) (PLA) films at different concentrations (3, 10, 15, 20 wt%). PLA were characterized using X-ray diffraction, SEM, TGA, DSC considering their mechanical properties migration. XRD analysis showed effective interaction between MMT oil. The...

Malfunctions in relay protection devices are predominantly caused by current transformer (CT) saturation which produces distortion measurements and disturbances power system protection. The development of deep learning is on the rise recently because its robustness. This study presents a CT detection where secondary becomes distorted. proposed scheme offers wide range consists moving-window tec...

Optical limiting performance, third-order nonlinearity chi(3), and nonlinear absorption properties have been investigated in a new class of azoarene phosphorus (V) porphyrins with charge transfer (CT) states. The introduction of axial azoarene groups into the phosphorus porphyrin structure is found to reduce the limiting threshold by a factor of 2 and lead to a rise in the second hyperpolarizab...

CONTEXT The use of cranial osteopathic manipulative medicine (OMM) to alter cerebral tissue oxygen saturation could play a role in the maintenance of cerebral homeostasis. OBJECTIVE To examine the effects of cranial OMM on cerebral tissue oxygen saturation (S(CT)O(2)) and cardiac autonomic function in healthy adults. METHODS Cranial OMM augmentation and suppression techniques and sham thera...

This paper presents an artificial neural network (ANN) based scheme for fault identification in power transformer protection. The proposed scheme is featured by the application of ANN to identifying system patterns, the unique choice of harmonics of positive sequence differential currents as ANN inputs, the effective handling of current transformer (CT) saturation with an ANN based approach, an...

In this paper, a study has been carried out to analyze the factors influencing the current transformer (CT) saturation factor (KS), in particular the secondary time constant (TS) of a CT. The study identifies and analyzes the optimum value for TS as this value varies. This paper also analyses and discusses the effect of TS to the KS factor in order to calculate the CT knee point voltage (VK) in...
