In this study, hyperpolarized (HP) 129 Xe MR ventilation and 1 H anatomical images were obtained from 3 subject groups: young healthy volunteers (HV), subjects with chronic obstructive pulmonary disease (COPD), and age-matched control subjects (AMC). Ventilation images were quantified by 2 methods: an expert reader-based ventilation defect score percentage (VDS%) and a semi-automatic ...
The total free energy to be minimized may be written as (1) G tot = f α G α + f 203 G 203 + f 227 G 227 + f 215 G 215 + f 012 G 012 where f i G i is the product of the mole fraction of phase i and the molar free energy of phase i.The superscripts 203, 227, 215, and 012 refer to the oxide phases Y 2 O 3, Y 2 Ti 2 O 7, Y 2 TiO 5, and TiO 2, respectively.The free energy of the solid solution ...

INTRODUCTION. Plant–plant interactions are important in mediating plant community structure, diversity and productivity in ecological systems (Pierik et al. 2013; Weidlich et al. 2018).The morphological plasticity of roots is a key trait in plant–plant interactions (Zhang et al. 2016).Plants can vary the investment in roots depending on the environment.

A site v = (x,d) specifies a location and direction within the tree, where x is the 3D location (x,y,z) within S A and d is a direction represented by a quaternion vector (X,Y,Z,W).A quaternion implicitly contains the direction and also an up vector to specify a complete camera orientation (Shoemake, 1985, Morrison, 1992).The direction is later used to obtain airway measurements as described ...

Ball Mill TRUNNION BEARINGS. Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion.
1. Introduction. Projections point out that population growth will occur at an accelerated rate until 2050 ().Consequently, renewable and non-renewable resources will be required to supply the primary human needs, such as food and housing (Marinova et al., 2020; Wang et al., 2021).Among non-renewable resources are minerals, water, fuels, and construction materials, the latter corresponding ...
Generally, plate count agar, or other general-use agar media, can be employed for nonspecific bacterial culture for total viable count (TVC). Selective and/or differential media are used for enumeration of specific classes of bacteria and pathogens (Gracias & McKillip, 2004; Kuria, Wahome, Jobalamin, & Kariuki, 2009; Lau et al., 2003).Each morphologically distinct colony (different colony …

stirred media mills and high-pressure grinding rolls, ball mills still retain a significant part of their importance in grinding, being widely used from minerals and cement, to chemicals and ceramics. The operation of a ball mill is a capital- and energy-intensive process, so that even mar-ginal improvements in their efficiency result in immense

The phenomenon of mode-mixing caused by intermittence signals is an annoying problem in Empirical Mode Decomposition (EMD) method. The noise assisted method of Ensemble EMD (EEMD) has not only effectively resolved this problem but also generated a new one, which tolerates the residue noise in the signal reconstruction.
