Joe Biden demands media declare total obedience to Democrats and blacklist all dissenting voices

(Natural News) For an American politician, Joe Biden plays a pretty good Nazi dictator, as he and his campaign staff prove once again that the Democrat Party no longer embraces core constitutional values such as freedom of expression and speech. The Biden campaign, already stung by a burgeoning scandal involving the former Veep’s corrupt dealings...

Abstract Novel molecularly imprinted polymer (MIP) for metformin was synthesized on the surface of magnetic multi-walled carbon nanotubes (MMWCNTs) as the support. Metformin was used as the template, methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linker and 2,2'-azoisobutyronitrile (AIBN) as the initiator. The synthesized composite was characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and Fourier transform infrared spectroscopy (FTIR). The surface molecularly imprinted composite ...

Abstract Steroid hormones, structural derivatives of cyclopentanoperhydrophenanthrene, play important roles in modulation of many physiological processes. Comprehensive characterization of steroid hormones is valuable for understanding the process of human life activities and even disease diagnosis. Hitherto systematical characterization of steroid hormones has been rarely investigated. Here, we presented an integrated method for human urine analysis based on ultra-high performance liquid chromatography-high resolution mass spectrometry in data-dependent acquisition mode with the following parallel reaction monito...

GuilemanyAbstractHydroxyapatite (HA) coatings onto Ti6Al4V alloy substrates were obtained by several thermal spray technologies: atmospheric plasma spray (APS) and high velocity oxy fuel (HVOF), together with the cold spray (CS) technique. A characterization study has been performed by means of surface and microstructure analyses, as well as biological performance. In-vitro tests were performed with primary human osteoblasts at 1, 7 ...

Publication date: Available online 15 October 2019Source: Materials Science and Engineering: CAuthor(s): M. Ramazanilar, A. MojraAbstractThe biological tissue could be considered as a porous matrix filled with the interstitial fluid. The tumoral tissue has a different permeability from the healthy tissue. With regard to this knowledge, the main objective of the present study is to study the tissue permeability as a diagnostic parameter for the detection of breast cancer. To this end, the healthy and the cancerous specimens of the breast tissue are taken from 17 female cases. All cancerous tumors are in the vascular phase o...

In this study, for developing a scaffold for tissue engineering from fish processing wastes, a hierachial collagen/gelatin/chitosan novel porous scaffold was fabricated using blends of collagen and gelatin extracted from the skins of Marine big eye snapper Priacanthus humrur. Scaffolds were developed by mechanical spinning of chitosan and by mixing of collagen and gelatin solutions followed by freeze drying and subsequent crosslinking of polymers. The scaffolds were evaluated for rheological properties – porosity, apparent density and swelling capacity to assess their mechanical property.Gelatin/chitosan composition ...

Publication date: December 2019Source: Food Packaging and Shelf Life, Volume 22Author(s): Jiahao Xu, Ru Song, Yubin Dai, Shuyi Yang, Jie Li, Rongbian WeiAbstractEpoxy resin was conjugated with zinc oxide nanoparticles (ZnO NPs) to prepare antibacterial zinc oxide-epoxy resin (ZnO-ER) composite. The property of ZnO-ER was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and SEM-energy dispersive X-ray spectroscopy (SEM-EDS) assays. Results showed the presence of ZnO NPs on the surface and cross-sections of ZnO-ER composite. The average thickness of ZnO-ER was 392.38 μm. The strong antibacte...

Ramon Canela-Garayoa Nine monoamides were synthesized from carboxylic acids (C8–C18) and crude glycerol. The final monoamides were the result of a rearrangement of the acyl chain during the final hydrogenation process. The purity of the final compounds was determined by spectroscopic and mass spectrometry (MS) techniques. The thermophysical properties of solid monoamides were investigated to determine their capability to act as phase change materials (PCM) in thermal energy storage. Thermophysical properties were determined with a differential scanning calorimeter (DSC). The melting temperatures of the analy...

ConclusionsWithin the main limitation of this pilot study, that is, the small sample, it is possible to state that cephalometric measurements on 3T-MRI seem to possess adequate reliability and repeatability and that they show satisfying agreement with values measured on CBCTs. An MRI examination does not expose patients to ionizing radiation and could provide an alternative to CBCT for three-dimensional cephalometrics in the future.
