SYNTHESIS OF ORPHENADRINE
Orphenadrine is an anticholinergic drug commonly used for painful muscle spasms and similar conditions. Orphenadrine can be synthesized in three steps starting from benzoyl chloride and toluene. In the first step Friedel crafts acylation is utilized to yield 3-methylbenzophenone from the aforementioned starting materi…
Polyploidy and hybridization patterns in the North American bluet genus Houstonia
Classic speciation models show that interspecific hybridization between diploid lineages is impeded by genetic incompatibilities.Recent models predict that single gene duplications may reduce genetic incompatibilities between species.In the context of these models, whole genome duplication (polyploidy) events would in…
A phylogenetic classification of Asphodelaceae subfamily Alooideae
Wood anatomy of three species of Ocimum Linn.and a variety namely O. basilicum, O. canum, O. gratissimum and O.basilicum var.purpurasens found in Ile-Ife Nigeria was investigated.This was done with a view to discovering additional characters that may be diagnostic and important in the identification and classification…
Smoke-derived compounds with germination activity: Towards understanding the mode of action by investigating structure-activity relationships of synthetic analogues
flowering season promoted greater seed set in R. milloides than in the more dispersed R. baurii var.platypetala.Neither selfing nor apomixis appear to be operating in these species, even though little pollinator activity was observed.Thus, viable seed production across these species' boundaries followed by vegetative…
Co-Cr wear particles and cobalt ions stimulate the expression of human general toxicology related genes on monocyte like U937 cells
Cobalt-chromium (Co-Cr) particles in the nanometre size range are produced by wear at the articulating surfaces of metal-on-metal implants, and are associated with inflammation, bone loss and implant loosening.
Utilization of functionalized graphene and its nanocomposites as a catalyst support in fuel cells
The production of novel catalyst support materials could open up new ways in order to enhance the catalytic activity by reduced catalyst loading. At this point, nanocomposites composed of conducting polymers like polypyrrole (PPy) reinforced with GNS are being considered as catalyst support for fuel cell applications.…

NMR studies of carbohydrate solvation in the room temperature ionic liquid 1-ethyl-3-methyl-imidazolium acetate
We have studied glucose, cellobiose and cellulose dissolution in the ionic liquid (IL) 1-Ethyl-3-Methyl-Imidazolium Acetate. These have been investigated using NMR and rheology. Though the samples have vastly different viscosities, depending on solute used, the microscopic properties are only dependent on the number o…
Prediction of Microstructure and Local Mechanical Properties for a CGI Crankcase
Non-uniform cooling conditions within a casting lead to locally differing microstructures, which result in locally differing mechanical properties. These have a tremendous impact on the behavior of the parts under their application load conditions and regarding their life time. The virtual development of castings can,…
Relationship between process technology, structure development, and fiber properties in modern carbon fiber production
The carbon fibre production based on polyacrylonitrile (PAN) is divided into two process steps: solution spinning of the precursor fibre and thermal conversion to the final carbon fibre. It is in the first step, the spinning of the precursor, where most of the properties of the final carbon fibre are determined. A hig…
Kristal Biru 2,3 dimetil-N-fenilalanin (DNF) Hasil Interaksi Kimia Padatan Asam Mefenamat dengan Asam Oksalat
1024x768 Salah satu cara untuk memperbaiki sifat fisikokimia suatu bahan aktif farmasi adalah dengan memanfaatkan reaksi kimia, seperti penggaraman dan pembentukan kompleks, atau interaksi fisika, seperti pembuatan dispersi padat yang memanfaatkan campuran eutektikum dan peritektikum, atau pembentukan persenyawaan mol…
Demonstrating the Use of Bisphenol A-functionalised Gold Nanoparticles in Immunoassays
Spherical gold nanoparticles (5-nm diameter) were modified with a small-molecule thiolated bisphenol A (BPA) ligand to achieve an estimated coverage of ~3.3 × 10–10 mol cm–2, or 180 ligands per particle. The modified particles were tested in an enzyme-linked immunosorbent assay (ELISA) format to measure functionality…
Experimental Investigation of Influence of Acoustic Wave on Vapour Precipitation Process
The measurement results of acoustic field parameters above electroplating bath, in presence of water vapour, are analyzed in this work. Suction was created by means of side exhausters. It is obtained that the sound field generator generated a sound level of 130–140 dB at frequency interval between 1 and 10 kHz. It is…
FIBRAS DE VIDRO: CARACTERIZAÇÃO, DISPOSIÇÃO FINAL E IMPACTOS AMBIENTAIS GERADOS
de extrema importncia que o crescente desenvolvimento das empresas e indstrias ande em linha tnue com a sustentabilidade. Aes sustentveis permitem que pouco ou nenhum resduo seja disposto em local potencialmente prejudicial ao meio ambiente, sendo que estes devem ser acompanhados e/ou gerenciados de forma que possam s…
Surface resistivity/conductivity of oxide–hydroxide compounds in inhibited seawater by optical interferometry
Optical interferometry techniques were used to measure the surface resistivity/conductivity of carbon steel samples in blank seawater and in seawater with different concentrations of a corrosion inhibitor, without any physical contact. The measurement of the surface resistivity/conductivity of carbon steel samples was…
Memory Effect in a Topological Surface State of Bi2Te2Se
We demonstrate the controllable local manipulation of the Dirac surface state in a topological insulator, Bi2Te2Se, which has suppressed bulk carrier density. Using scanning tunneling microscopy/spectroscopy under magnetic fields, we observe Landau levels of the Dirac surface state in the conductance spectra. The Land…
Adsorption of divalent metals on natural and functionalized nontronite hybrid surfaces: An evidence of the chelate effect
Nontronite is an important phyllosilicate with a high concentration of ferric iron in the octahedral layer. A new occurrence of Brazilian nontronite sample was used for the organofunctionalization process with 3-aminopropyltriethoxysilane. Due to the increment of basic centers attached to the pendant chains, the metal…
Radiological risk assessment of natural radionuclides in sand collected from some beaches along the coastline of southwestern Nigeria
The activity concentrations of natural radionuclides in sand from three beaches in southwestern Nigeria had been determined employing the gamma-ray spectroscopy method. The mean activity concentrations of (226)Ra, (232)Th and (40)K, respectively, were 12.5 ± 3.3, 25.8 ± 4.7 and 153.9 ± 18.5 Bq kg(-1) for Suntan Beach,…
