Residential Pharmaceutical Deliveries: SWOT and TOWS Analyses of Drone Delivery Service
No full textThe purpose of this exercise is to evaluate drone delivery service in the healthcare sector as a proposed means for residential pharmaceutical deliveries. The study will use SWOT to analyze the internal and external environment. In addition, TOWS analysis technique is used to identify the relationship between factors and develop the best strategy for drone deliveries. SWOT and TOWS are an acronym for strengths, weaknesses, opportunities, and threats. PUBMED, ScienceDirect, and Google scholar are used to look for articles about drones. Articles about the use of drones in the military or warfare are excluded. Drones and their use in the health care sector are examined for their strengths and weaknesses. The external environment's opportunities and threats are also evaluated to be taken advantage of or avoided. The findings of this study reveal that drone delivery in residential markets will lower delivery costs, resulting in high demand for orders in the delivery market, which will benefit both medical care and the health industry

Pawpharos: Pet Tracking Utilizing Bluetooth Low Energy Tags
No full textBluetooth low energy tags are popular for their price, availability, and convenience. Utilizing this technology, a product was formulated to track the location of pets by pinging the Bluetooth signal off of Raspberry Pi Zero “sniffers”, and being able to see it through an account on the Pawpharos webpage. This allows for tracking from anywhere, which is not only convenient, but also helps pet safety and security, especially with owners that may not be home much of the time
Dry needling for spine related disorders: A scoping review
No full textThe depth and breadth of research on dry needling (DN) has not previously been evaluated for symptomatic spine related disorders (SRD) from myofascial trigger points (TrP), disc, nerve and articular structures that are not due to serious pathologies. Current literature appears to generally support DN for treatment of TrP. The authors performed a scoping review on DN conducted following Levac et al.’s [1] five part framework to determine the current state of the literature regarding DN for patients with SRD. This poster identifies the research on DN treatment for SRD, and describes treatment sites, frequency of treatment and outcomes studied
Ascorbic Acid Determination in Chinese Hamster Ovary Cells Exposed to Nickel and Chromium
No full textEpidemiological and in-vitro studies report populations exposed to environmental mixtures of heavy metals have shown increased cancer rates. In order to study this damage,
cytogenetic tests are suitable methods for identifying DNA damage caused by these complex mixtures. Therefore, the chemical interaction is of major concern in the assessment of risk by regulatory agencies. Epidemiological and in-vitro studies reported that Ni(II) and Cr(VI), at relevant environmental levels, have an antagonistic effect in the induction of cytogenetic effects in cell culture. This antagonism can be explained by the hypothesis that Cr(VI) readily crosses the cell membrane and the ability of Ni(II) to form a stable complex with ascorbic acid (ascorbate) and interfere with the normal interconversion between ascorbate(Asc) to DHA, which is an important process for the reduction of Cr(VI) to its active genotoxic form Cr(III). To study the role of ascorbic acid, a reducing agent, in the reduction of Cr(VI) to Cr(III), Chinese Hamster Ovary (CHO) cells were treated with Ni(II) and Cr(VI) alone and in combination and the ascorbate concentration of each treatment was measured
Portable Car-Washing System
No full textThe Portable Car-Washing system was developed for the benefits of improving consumer focus. The system was designed to provide comfort, convenience, improve health, and durability to consumer vehicles. Many consumers face scenarios where their vehicles are being damaged by car washing companies. In fact, car wash companies are known to tear off antennas, side view mirrors, and front/ rear bumpers. Also, harsh chemicals and low-quality car shampoo are being used at these establishments which eventually cause rust. These harsh chemicals can vary from all brands of industrial strength alkaline enhanced degreasing shampoo which leads to oxidation of the paint and corrosion. On the other hand, devices such as the Portable Car- Washing system are innovating a touchless car wash facility introducing a safer washing system
Impact of the edTPA on teacher candidates’ perceptions of preparedness to teach
No full textThis case study situated at a private University in the northeastern United States explored the impact of the edTPA assessment and preparation process as an embedded component of the University’s educator preparation program. The study tracked 59 graduate level candidates from entry in the program through candidate licensure. The researchers examined the impact of the edTPA preparation process on teacher candidates’ perceptions of their readiness to teach in comparison to their actual readiness to teach as indicated by their edTPA portfolio score. The University’s School of Education has 30% ethnic diversity, thus a second research question compared perceptions of readiness to teach of Candidates of Color to those of White peers. Framed by Bandura’s (1977) self-efficacy theory, this study contributes to the research on the edTPA as an efficacious and inclusive evaluation tool particularly within diverse schools of education

Decoding Extreme High Density 2D Matrix Barcodes: Circumventing Edge Aliasing
No full textAny combination of printing and imaging technologies has inherent limitations with respect maximum achievable 2D matrix barcode density. State of the art decoding techniques rely heavily on code specific “helper features” like: reference edges, clock tracks, and ECC.
This means:
-Decoder cannot function without “helper” features
-Even minor “helper” damage renders code unreadable
-Maximum code density is limited
-Localized bit grid distortions are not well accommodated
Achieve reliable decoding of Extreme High Density 2D Barcodes (less than 2 image pixels per module) using:
1.“Alias disambiguation" at code densities high enough to produce aliasing in the code image
2.“Bit Modeling" to compensate for inherent linear and nonlinear behaviors of the printing and imaging processe
Natural diatoms dopped with AuNPs as drug delivery systems and comparison with diatoms decorated with graphene
No full textThe use of natural diatoms is currently a topic of interest for therapeutic applications due to its facilities, low cost, and biocompatibility. Here a comparison between a previous work of diatoms dopped with AuNPs and the possibility of what oculd be adding graphene to the system, or as a replacement of the AuNPs. Here, are reported the chemical modification of diatoms Aulacoseria genus microalgae-derived biosilica from Guayllabamba - Ecuador decorated with gold nanoparticles by In-situ and Ex-situ methods to study the in vitro gentamicin loading and release properties in simulated body fluid (SBF) from the paper “Natural diatoms dopped with AuNPs as drug delivery systems” . Successful decoration of the diatoms and loaded with gentamicin was confirmed using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Raman spectroscopy and Fluorescence Microscopy. It follow the In-vitro drug release by using Ultraviolet-Visible Spectroscopy (UV–vis). The results revealed that diatoms decorated with gold nanoparticles using the Ex-situ method (Au/CTAB-Diatom) showed a faster release reaching a maximum of 93% in 10 days and a lower loading rate, while the samples decorated by the In-situ method presented longer and slower release behavior. Fluorescence properties were enhanced after the gentamicin loaded. The advantage of this work is the control of the structural and optical properties of diatoms deco- rated with gold nanoparticles for the gentamicin drug delivery. As for the graphene adhesion is a similar protocol as the decoration with AuNPs, acquiring new features that would be study in next works
