Linear-constant velocity-pressure elements are enriched with residual-free macro bubbles. Static condensation prompts a stabilized method for this element, where mesh-dependent jumps of the normal stress are added across internal edges of the underlying macroelements. This procedure renders the SIMPLEST element stable.

In this study, in the removal of macro (P, S, Na, K, Ca, Mg) and micro (Sb, Ba, Co, Cu, Fe, Pb, Mn, Hg, Mo, Se, Ag, Zn) elements in the effluent of Elazig Wastewater Treatment Plant, the efficiency of Lemna minor L. and Lemna gibba L. has been studied comparatively. For this aim, fronds of these plants have been adapted to the effluent of the treatment plant that feeds pilot scale reactors. The...

A simple procedure to formulate efficient and stable hybrid/mixed finite elements is developed, for applications in macroas well as micromechanics. In this method, the strain and displacement field are independently assumed. Instead of using two-field variational principles to enforce both equilibrium and compatibility conditions in a variational sense, the independently assumed element strains...

There have been many attempts to give a coherent formulation of a hierarchical progression that would lead to a refined partition of the vast area stretching from the context-free to the context-sensitive languages. The purpose of this note is to describe a theory that seems to afford a promising method of interpreting the tree adjoining languages as the natural third step in a hierarchy that s...

The competitive scenario in recent decades has imposed increasing levels of complexity and interdependence to companies, which try to respond to this challenge providing some organizational changes, such as collective arrangements. This article aims to understand the emerging collective competencies based on the mobilization of different working groups to make the turnaround maintenance (TM) po...

We investigate a macro-element variant of the hybridized discontinuous Galerkin (HDG) method, using patches standard simplicial elements that can have non-matching interfaces. Coupled via HDG technique, our method enables local refinement by uniform subdivision each macro-element. By enforcing one spatial discretization for all macro-elements, we arrive at problems per are embarrassingly parall...

The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...

This study was conducted to determine the effect of compost and compost tea on growth and physiological parameters of Lepidium sativum L. 30-day-old Cress plants treated with compost and compost tea were harvested and different growth and physiological parameters were measured. Compost tea application increased RGR, SLA, ULR and RLAGR. The contents of Chlorophyll a and Chlorophyll b in the plan...

Question: Cocos nucifera, the coconut palm, has a pantropical distribution and reaches near monodominance in many atolls, low lying islands and coastal regions. This paper examines the ecological correlation between C. nucifera abundance and changes in forest structure, floristic diversity and forest soil characteristics. Location: Palmyra Atoll NWR (USA), Central Pacific Ocean. Methods: Plant ...

This paper describes the ANSYS simulation of an electrostatically-actuated MEMS device, in which the drive voltages are computed using feedback control laws. The device consists of a movable electrode suspended on flexible, elastic structures, and one or more fixed drive electrodes. The feedback control laws are used to determine the level of a variable voltage supply in a drive circuit for eac...
