Cadmium (Cd) is one of the most commonly detected toxic heavy metals in the environment. Ferrous sulfide (FeS) nanoparticles were prepared using sodium carboxymethyl cellulose (CMC) as a stabilizer and tested for removal of Cd from aqueous solutions. Effects of CMC concentration, initial Cd concentration, pH, humic acid (HA) and dissolved oxygen were examined. Fully stabilized FeS (100 mg/L) nanoparticles were obtained using 0.01 wt% CMC. Batch kinetic tests showed that the nanoparticles at 1…

The halogenated derivatives of N-(2-methoxy)benzyl-2,5-dimethoxyphenethylamine (25-NBOMe) such as the 4-bromo analogue (25B-NBOMe) represent a new class of hallucinogenic or psychedelic drugs. The purpose of this study was to determine the role of the electron-donating groups (halogen and dimethoxy) in the pathway of decomposition for the distonic molecular radical cation in the electron ionization mass spectrometry (EI-MS) process of the trifluoroacetamide (TFA) derivatives.The systematic re…

Intelligent packaging can provide better preservation and advanced convenience for consumers. In this study, corn starch and polyvinyl alcohol (PVA) were used to produce films. Two easily accessible anthocyanin sources-purple sweet potato extracts (PSPE) and red cabbage extracts (RCE), were added respectively to evaluate their potential of indicating food freshness. Film incorporated with PSPE or RCE showed distinguishable color changes in different buffers. Water vapor permeability (WVP) was…

We have prepared the hydrogen sulfide trimer and tetramer anions, (HS) and (HS), measured their anion photoelectron spectra, and applied high-level quantum chemical calculations to interpret the results. The sharp peaks at low electron binding energies in their photoelectron spectra and their diffuse Dyson orbitals are evidence for them both being dipole-bound anions. While the dipole moments of the neutral (HS) and (HS) clusters are small, the excess electron induces structural distortions t…

Inoculation of bermudagrass with rhizobacterial biostimulants can increase plant growth and influence relationships with grass-feeding herbivores. Tunneling and root-feeding behaviors of tawny mole crickets cause severe damage to grass in pastures, golf courses, and lawns. The goal of this study was to determine if inoculation of bermudagrass by a rhizobacteria blend (plant growth-promoting rhizobacteria, PGPR) increases the tolerance of hybrid bermudagrass to tawny mole crickets in captivity…

Although helping behavior at work is widely studied, little is known about the processes via which help providers increase or decrease their helping behavior. In the current research, we integrated both enrichment-based and depletion-based perspectives on helping with Kahn’s psychological conditions for engagement to offer more comprehensive understanding of how helping behavior may change. Specifically, based on Kahn’s model, we simultaneously consider the beneficial effects of helping on he…

Researchers frequently argue that a child's engagement in stereotypy may compete with his ability to acquire academic skills, engage in appropriate social interactions, or both; however, few studies have directly tested these suppositions. We used a five-phase assessment to evaluate the extent to which behavioral interventions with a progressively greater number of components were necessary to decrease stereotypy and increase correct responding during academic instructions for five children d…

Ectoparasitic flatworms of Nasicola (Monogenoidea: Capsalidae), which infect nasal epithelium of true tunas (Thunnus spp.), are not well studied, nor have their impacts on the host's olfactory organ been evaluated. Infections of Nasicola hogansi on Atlantic bluefin tuna, Thunnus thynnus, were investigated with emphasis on the relationship between infection prevalence, abundance and mean intensity with bluefin tuna size, sex, body condition and capture month, as well as histopathological effec…

Emotional reactivity has been implicated in the development and maintenance of anxiety. The metacognitive model suggests that maladaptive metacognitive beliefs (i.e. beliefs about thinking) may increase the impact of emotional reactivity on anxiety. As such, the purpose of the present study was to examine maladaptive metacognitive beliefs as a moderator of the relationship between emotional reactivity and anxiety in an undergraduate student sample ( = 78). Participants completed a battery of …

The Distress Tolerance Scale (DTS) is a self-report measure of perceived capacity to withstand aversive emotions. Initial factor analysis of this measure suggested a structure comprising one higher-order factor and four lower-order domain-specific factors. However, there is limited evidence in support of the DTS's purported multidimensionality, and despite use of the DTS subscales, research has yet to assess their incremental utility. The current investigation sought to rectify the paucity of…
