Students\u27 Attitudes Toward the Smithfield Vocational Department

The basic objectives of this study were as follows: 1. To identify student views of vocational education at Smithfield High School by conducting a survey; 2. To analyze the differences in reasons why the academic students and vocational students selected to enroll in their specific concentrations

A Case By Case Exploration of Accountancy Issues in Corporate Reporting

The following are solutions to a series of cases based on relevant and prevalent accounting issues in corporate financial reporting. Each case was completed in partial requirement of the honors ACCY 420 course at the University of Mississippi. The ACCY 420 course was an academic year long course, spanning the fall 2016 and spring 2017 semesters. Each case was focused on a specific accountancy issue in corporate reporting. Some cases are directly related to public companies whereas others are specific to the accountancy issue. Accordingly, each case is different. Some cases involve a combination of ratio analysis, the preparation of journal entries financial statements, and professional judgement. Others, involve one or more of the latter elements

17. Increase in Social Media Use to Support Increased Meal Preparation by College Students during the COVID-19 Experience

Background The COVID-19 pandemic has resulted in higher education institutions transitioning to online course delivery and limiting on-campus activities. With decreasing access to campus food service and restaurants, college students with limited cooking experience are now reliant on home-prepared meals. Purpose The purpose of this study was to explore cooking skills and social media use for meal preparation in college students during the COVID-19 experience. Method This cross-sectional descriptive study utilized an online survey with U.S. college students early in the Covid-19 pandemic. The subset of questionnaire items used for this study included demographic, social media use, and cooking and shopping behaviors items. Results Nearly 30% of the college student respondents (N=282) self-identified as the primary person responsible for preparing meals in their homes, while 40% had shared responsibility. Over 50% of the respondents reported increasing meal preparation activities during the quarantine. At the same time, 64% increased their use of social media for researching food preparation techniques and recipe ideas. Sixty-two percent described having “good” grocery shopping skills, while only 51% described their cooking skills as “good”. Conclusions There is an identified need for providing food preparation and shopping skills education to support college students’ ability to manage and adapt during disruptive times

New trends for metal complexes with anticancer activity

Medicinal inorganic chemistry can exploit the unique properties of metal ions for the design of new drugs. This has, for instance, led to the clinical application of chemotherapeutic agents for cancer treatment, such as cisplatin. The use of cisplatin is, however, severely limited by its toxic side-effects. This has spurred chemists to employ different strategies in the development of new metal-based anticancer agents with different mechanisms of action. Recent trends in the field are discussed in this review. These include the more selective delivery and/or activation of cisplatin-related prodrugs and the discovery of new non-covalent interactions with the classical target, DNA. The use of the metal as scaffold rather than reactive centre and the departure from the cisplatin paradigm of activity towards a more targeted, cancer cell-specific approach, a major trend, are discussed as well. All this, together with the observation that some of the new drugs are organometallic complexes, illustrates that exciting times lie ahead for those interested in ‘metals in medicine

Current applications and future potential for bioinorganic chemistry in the development of anticancer drugs

This review illustrates notable recent progress in the field of medicinal bioinorganic chemistry as many new approaches to the design of innovative metal-based anticancer drugs are emerging. Current research addressing the problems associated with platinum drugs has focused on other metal-based therapeutics that have different modes of action and on prodrug and targeting strategies in an effort to diminish the side-effects of cisplatin chemotherapy

Encapsulation of cadmium selenide nanocrystals in biocompatible nanotubes: DFT calculations, X-ray diffraction investigations and confocal fluorescence imaging

The encapsulation of CdSe nanocrystals within singlewalled carbon nanotubes (SWNTs) cavities of varying dimensions at elevated temperatures under strictly air-tight conditions is described for the first time. The structures of CdSe nanocrystals under confinement inside SWNTs was established in a comprehensive study, combining both experimental and DFT level theoretical investigations. The calculated binding energies show that all considered polymorphs (3, 3), (4, 4) and (4,2) may be obtained experimentally. The most thermodynamically stable structure (3:3) is directly compared to the experimentally observed CdSe structures inside carbon nanotubes. The gas-phase density functional theorycalculated energy differences between “free” 3:3 and 4:2 structures (e.g. whereby 3:3 models a novel tubular structure in which both Cd and Se form three coordination as observed experimentally for HgTe inside SWNT and 4:2 is a motif derived from the hexagonal CuI bulk structure in which both Cd and Se form 4 or 2 coordinations) are surprisingly small, only 0.06 eV per formula unit.. X-ray powder diffraction, Raman spectroscopy, High-resolution transmission electron microscopy (HRTEM) and Energy Dispersive X-ray (EDX) analyses led to the full characterization of the SWNTs filled with the CdSe nanocrystals, shedding light on the composition, structure and the electronic interactions of the new nanohybrid materials on an atomic level. A new emerging hybrid nanomaterial, simultaneously filled and beta-D-glucan coated was obtained using pristine nanotubes and bulk CdSe powder as starting materials. This displayed fluorescence in water dispersions and unexpected biocompatibility was found to be mediated by the beta-D-glucan (a biopolymer extracted from barley) with respect to that of the individual inorganic materials components. For the first time, such supramolecular nanostructures are investigated by life-sciences techniques applied to functional nanomaterials characterization opening the doors for future nano-biotechnological applications

Maleimide-functionalised platinum(IV) complexes as synthetic platform for targeted drug delivery

Molecularly imprinted polymer based on MWCNTs-QDs as fluorescent biomimetic sensor for specific recognition of target protein

A novel molecularly imprinted optosensing material based on multi-walled carbon nanotube-quantum dots (MWCNT-QDs) has been designed and synthesized for its high selectivity, sensitivity and specificity in the recognition of a target protein bovine serum albumin (BSA). Molecularly imprinted polymer coated MWCNT-QDs using BSA as the template (BMIP-coated MWCNT-QDs) exhibits a fast mass-transfer speed with a response time of 25 min. It is found that the BSA as a target protein can significantly quench the luminescence of BMIP-coated MWCNT-QDs in a concentration-dependent manner that is best described by a Stem-Volmer equation. The K-SV for BSA is much higher than bovine hemoglobin and lysozyme, implying a highly selective recognition of the BMIP-coated MWCNT-QDs to BSA. Under optimal conditions, the relative fluorescence intensity of BMIP-coated MWCNT-QDs decreases linearly with the increasing target protein BSA in the concentration range of 5.0 x 10(-7)-35.0 x 10(-7) M with a detection limit of 80 nM
