Multiple Intelligences Of Students At Jordanian Universities
The present study aimed at investigating different intelligence types among Jordanian students at different public and private universities in Jordan. To achieve such aim, it sought to identify and rank multiple intelligences that characterize students at Jordanian universities, and to identify and rank the differences in multiple intelligences according to some variables: the gender, university (public or private), the students’ averages, the students’ specializations and the academic year. This study has used a survey as an instrument of collecting data. The study sample consisted of (1436) students from the University of Jordan, Yarmouk University, Al-Hashemaya University, the University of Sciences and Technology, Petra University, Al-Zarqa University, Amman Arab University, Al-Isra' University, Al-Zaitunah University and Philadelphia University. The students estimated their own IQ scores on each of Gardner’s 7 multiple intelligences: logical\ mathematical IQ, musical IQ, interpersonal IQ, Kinesthetic IQ, Intra-personal IQ, Linguistic IQ and Spatial IQ. After analyzing the data, T-Test indicated that interpersonal intelligence is the highest and the most common intelligence among Jordanian students. Following are Intra-personal, Kinesthetic, Linguistic, Spatial, logical\ mathematical, and musical, respectively. There were significant differences among Jordanian students in the linguistic and interpersonal intelligence in favor of the females. There were significant differences in the logical intelligences in favor of the governmental universities. There were no significant differences in the multiple intelligences that can be attributed to the averages of the students. There were significant differences in the musical intelligence in favor of the graduates
Synthesis, physicochemical, conformation and quantum calculation of novel N-(1-(4-bromothiophen-2-yl)ethylidene)-2-(piperazin-1-yl)ethanamine Schiff base
N-(1-(4-bromothiophen-2-yl)ethylidene)-2-(piperazin-1-yl)ethanamine Schiff base ligand was prepared in very good yield by condensation of equimolar amounts of 1-(4-bromothiophen-2-yl)ethanone with 2-(piperazin-1-yl)ethanamine under reflux condition using alcohol media. The desired Schiff base was analyzed on the basis of its MS, elemental analysis, UV-visible, FT-IR and NMR analysis. The E and Z optimization was performed to figure out the most stable isomer. Several DFT quantum calculation like: TD-SCF, MPE, IR-vibration, NMR, Mulliken population were carried out by B3LYP level of theory. The experimental analyses of the compound were compared to their theoretical coordinates
Synthesis and Spectral Identification of Three Schiff Bases with a 2-(Piperazin-1-yl)-N-(thiophen-2-yl methylene)ethanamine Moiety Acting as Novel Pancreatic Lipase Inhibitors: Thermal, DFT, Antioxidant, Antibacterial, and Molecular Docking Investigations
Three new tetradentate NNNS Schiff bases (L1–L3) derived from 2-(piperidin-4-yl)ethanamine were prepared in high yields. UV–Visible and FTIR spectroscopy were used to monitor the dehydration reaction between 2-(piperidin-4-yl)ethanamine and the corresponding aldehydes. Structures of the derived Schiff bases were deduced by 1H and 13C NMR, FTIR, UV–Vis, MS, EA, EDS, and TG-derived physical measurements. DFT/B3LYP theoretical calculations for optimization, TD-DFT, frequency, Molecular Electrostatic Potential (MEP), and highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) / were performed for L2. The in vitro antimicrobial activities of the three Schiff bases were evaluated against several types of bacteria by disk diffusion test using Gentamicin as the standard antibiotic. Schiff bases revealed good antioxidant activity by the DPPH method, and the IC50 values were compared to the Trolox standard. Pancreatic porcine lipase inhibition assay of the synthesized compounds revealed promising activity as compared to the Orlistat reference
Synthesis, physico-chemical, hirschfield surface and DFT/B3LYP calculation of two new hexahydropyrimidine heterocyclic compounds
Two new hexahydropyrimidine compounds were prepared in high yield by condensation of an equimolar amount of 1,3-diamine with 2-dipyridylketone at room temperature in dichloromethane. The desired hexahydropyrimidine structures were confirmed on the basis of their UV-Visible, elemental analysis, FT-IR,1H-NMR, TG/DTG and EI-MS data. Hirschfield and DFT/B3LYP theoretical analyses were performed and their output results were compared to experimental data. - 2019, Iranian Institute of Research and Development in Chemical Industries.
