Sustainable solutions are investigated to reduce the environmental damage caused by greenhouse gases and CO2 emissions. Cement is a construction material responsible for Thus, emissions reduced using replacement materials such as rice husk ash instead of cement. This study durability mechanical properties lightweight high-performance, sustainable cement-based composites. A foaming agent was use...

In light of the recent data from BES collaboration for χc0 → V V , PP and SS, and from CLEO-c for ηη, η′η′ and ηη′, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as χc0,2 → V V , PP and SS in a recently proposed parametrization scheme. An overall agreement with the data is achieved in χc0,2 → V V and PP , while in χc0 → SS we find that a possible ex...

This paper presents the first family of conforming finite element $\ddiv\ddiv$ complexes on tetrahedral grids in three dimensions. In these complexes, spaces $H(\ddiv\ddiv,\Omega;\Sbb)$ are from a recent article [L. Chen and X. Huang, Math. Comp., 91 (2022), pp. 1107--1142] while both $H(\sym\ccurl,\Omega;\Tbb)$ $H^1(\Omega;\R^3)$ newly constructed here. It is proved that exact. As result, they...

MENT OF OBSTETRIC PROBLEMS. Edited by T. Barnett and J. J. Foley. (Pp. xiii+ 188; illustrated. 50s.) Oxford: Pcrgamon Press, 1963. THIS is the transcript of proceedings at the first Obstetric Coonference held under the auspices of the South-WVestern Obstetrical and Gv-nacological Society in Portsmouth in November, 1961. There were five sessions, devoted to the very important practical subjects ...

The interpretation of modified PPs, like one meter behind the desk, far outside the village, or right under the lamp has never received much attention in the literature about prepositions. However, as this paper shows, the modification of PPs presents an intriguing problem for a compositional semantics of PPs. This problem can be solved when the PP is interpreted, not as a set of points or mere...

Findings from recent eye-tracking studies suggest that adults prefer to rely more on recently seen events than possible future events during sentence comprehension: When the verb in an NP1-VERB-ADV-NP2 sentence was referentially ambiguous between a recent action and an equally possible future action, adults fixated the target of the recent action more often than the not-yet-acted upon object (K...
