This study aimed to examine nonverbal expressions of older adults performing a Feeling-of-Knowing (FOK) metamemory task, since nonverbal cues are considered to serve as indicators of memory deficit awareness. In a production experiment, we collected a variety of recalled and unrecalled answers from older adults (mean age = 79.5) and tested their accuracy. Nonverbal behavior was annotated manual...

sorption reactions in many heterogeneous systems are important. adsorption is a time dependent process and knowing the adsorption rate is essential for designing, evaluating and recovering the adsorbents. at the present study, an ammonium adsorption kinetic experiment by some soils series of golestan provice, which is varying in mineralogical and textural properties was conducted using solution...

BLOCKIN We BLOCKIN BLOCKIN have BLOCKIN BLOCKIN been asked by the editors of the Journal of Philosophical Logic to write a short comment on his most recent work, published in this issue, based in part on a referee report by one of us, that, unfortunately, did not reach Aldo in time.

Overfitting in multilayer perceptron (MLP) training is a serious problem. The purpose of this study is to avoid overfitting in on-line learning. To overcome the overfitting problem, we have investigated feeling-of-knowing (FOK) using self-organizing maps (SOMs). We propose MLPs with FOK using the SOMs method to overcome the overfitting problem. In this method, the learning process advances acco...

the effective removal of dyes from aqueous wastewaters is among the most important issues formany industrialized countries. removal of congo red (cr) dye from aqueous solutions was studiedusing nickel oxide nanoparticles. the operating variables studied were initial ph of solution,adsorbents dosage, temperature and contact time. the morphological information of nickel oxidenanoparticles were ch...

OBJECTIVES Prior research found age invariance in accuracy of delayed judgments of learning accuracy (Eakin, D. K., & Hertzog, C. [2006]. Release from implicit interference in memory and metamemory: Older adults know that they can't let go. The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences, 61, 340-347). We tested whether aging affects accuracy of feeling of know...

TB) is still a major problem globally Background: Mycobacterium tuberculosis and especially in Africa. Vitamin D deficiency has been linked to TB in the past and studies have found vitamin D deficiency to be common among Ugandan TB patients. The functional activity of vitamin D is dependent on the genotype of the vitamin D receptor (VDR) polymorphic genes. Recent findings have indicated that VD...

in the present study, hydrilla verticillata biomass was investigated as a novel biosorbent for the uptake of basic dye malachite green from its aqueous solution. kinetic and equilibrium studies were carried out in batch process. batch adsorption experiments were conducted to study the effect of ph, temperature, sorbent dosage, initial dye concentration, and contact time for the removal malachit...

abstractthe purpose of this study was to investigate the controllable operating parameters influence, including ph, solid content, collector, co-collector, and depressant dose, and conditioning time, on apatite flotation kinetics. four first order flotation kinetic models are tested on batch flotation time-recovery profiles. the results of batch flotation tests and the fitting of first-order ki...
