What is the mechanism behind the mitigation of ICP by incorporating CNTs with FO membrane?5 answersThe incorporation of carbon nanotubes (CNTs) in forward osmosis (FO) membranes aids in mitigating ion concentration polarization (ICP) through various mechanisms. CNTs enhance water flux, reduce reverse solute flux, and minimize membrane fouling, ultimately improving membrane selectivity and performance. Additionally, CNTs exhibit good electroconductivity, enabling electro-assistance in membrane processes, leading to increased permeate flux and enhanced removal efficiency of contaminants. Moreover, entangled single-wall carbon nanotube (SWNT) films have been explored as ion-selective membranes, offering insights into the relationship between electrical properties and ion transport in micro-nanofluidic systems, potentially influencing ICP behavior. Overall, the incorporation of CNTs in FO membranes not only enhances water treatment efficiency but also plays a crucial role in reducing ICP effects through improved membrane properties and electro-assistance mechanisms.
What is Internal Control?4 answersInternal control is a method used by managers and company leaders to increase the efficiency and effectiveness of bank performance and minimize credit payment arrears. It is a process established and managed by the management board and lower managers to provide reasonable assurance about achieving goals related to efficiency, effectiveness, financial reporting quality, compliance, and property protection. In modern conditions, internal control is becoming one of the most important elements of effective enterprise management, enabling organizations to prevent losses and achieve planned results. It is a plan, method, procedure, and policy designed by management to ensure operational efficiency, control of financial reporting, asset security, and compliance with laws and regulations. Internal control is imposed by management to give belief in the achievement of corporate objectives related to operations, financial reporting, and compliance.
How does globalization affect polarization?5 answersGlobalization has been found to have a decreasing effect on polarization. The studies show that economic and political globalization measures are negatively related to indicators of polarization. The effects of globalization on polarization can be observed in different aspects such as society and politics. The process of globalization has been shown to decrease social polarization in EU member countries. Additionally, foreign technological convergence has been identified as an important source of wage polarization. The catching-up of foreign countries in terms of technological innovation has contributed to the polarization of the US labor market. The increase in wealth-to-income ratio in the US has also been linked to foreign technological catching-up.
Why polarization is important in plasmas?4 answersPolarization is important in plasmas because it affects various aspects of plasma behavior and interactions. In gyrokinetic theory, the polarization effects are analyzed by using hybrid coordinates, which include the nonlinearity of polarization displacement. The generation and transport of fast electrons in laser-plasma interactions are influenced by the polarization of the laser pulse. Plasma polarization spectroscopy provides valuable information about high energy density plasmas, including the existence, directionality, and energy of particle beams. In the context of AdS/CFT holography, the polarization coefficients of a strongly-coupled plasma are related to the tidal deformation coefficients of a black brane. The polarization properties of gamma photons emitted from a plasma can be used to probe the plasma dynamics and its susceptibility to quantum electrodynamical processes.
Can polarization be used to detect nerves?4 answersPolarization can be used to detect nerves. Polarization-sensitive optical coherence tomography (PS-OCT) has been shown to visualize birefringent structures in both rat and human prostate specimens, which were confirmed to be nerves by histology or multiphoton microscopy. PS-OCT imaging of human prostatectomy specimens also revealed spatial variation in the amount of birefringent fibrous structures, consistent with anatomy. PS-OCT has also been used to visualize the orientation of nerves in the retinal nerve fiber layer (RNFL) and collagen fibers in peripapillary sclera in healthy volunteers. Additionally, the polarization of an optical image has been shown to be a potential way to make target detection and identification easier with higher accuracy. Therefore, polarization can be a useful tool for detecting nerves in various applications.
