The commingled microbial moiety of oxygenic photogranules (OPGs) facilitates aeration-free wastewater treatment. Embedded in an extracellular polymeric substances (EPS) matrix, producers and consumers oxygen occupying granular niches exchange substrates among themselves with the bulk fluid. An assessment OPG’s phototrophic potential or functional capacity may require combining different photoac...

‎In the present study‎, ‎we consider a regular curve in Galilean‎ ‎$4$-space $mathbb{G}_{4}$ whose position vector is written as a‎ ‎linear combination of its Frenet vectors‎. ‎We characterize such‎ ‎curves in terms of their curvature functions‎. ‎Further‎, ‎we obtain‎ ‎some results of rectifying‎, ‎constant ratio‎, ‎$T$-constant and‎ ‎$N$-constant curves in $mathbb{G}_{4}$‎.

China’s rapid industrialization and urbanization in recent decades have deteriorated its water resource quality. This study focused on pollution terms of the chemical oxygen demand (COD) levels ammonia nitrogen industrial household discharges different Chinese provinces. Although heterogeneity environmental Kuznets curves (EKCs) from provinces has been studied, positions provincial EKCs (which ...

We develop a Bayesian method for nonparametric model–based quantile regression. The approach involves flexible Dirichlet process mixture models for the joint distribution of the response and the covariates, with posterior inference for different quantile curves emerging from the conditional response distribution given the covariates. An extension to allow for partially observed responses leads ...

A study of the normal modes of vibration and their dispersion in polyinosinic acid [poly (I)] along the helix axis based on Urey-Bradley force field is reported. It leads to a better interpretation of Raman and FTIR spectra. A comparison of dispersion curves of poly (I) with poly (G) has been made. Characteristic features of dispersion curves, such as regions of high density-of-states, repulsio...

In this work, we analyze the influence of masonry infill walls on the seismic performance of waffle slabs reinforced concrete (RC) framed structures. We analyze buildings of three, five and eight storeys, which are representative for a big number of housings in Barcelona, Spain. Capacity spectra have been obtained by performing pushover analyses and we have used a simplified procedure to obtain...

Global convergence results are derived for well-known conjugate gradient methods in which the line search step is replaced by a step whose length is determined by a formula. The results include the following cases: 1. The Fletcher-Reeves method, the Hestenes-Stiefel method, and the Dai-Yuan method applied to a strongly convex LC objective function; 2. The Polak-Ribière method and the Conjugate ...
