The currently available data on the distribution of C2 fracture subtypes is sparse. This study was designed to identify the proportions of the second cervical vertebra (C2) fracture subtypes and to present age and gender specific incidences of subgroups. A dataset of all patients treated between 2002 and 2014 for C2 fractures was extracted from the regional hospital information system. C2 fract...

Copper and its oxides are the main catalyst materials able to promote formation of hydrocarbons from electrocatalytic CO2 conversion. Herein, we describe a novel preparation method for carbon-doped copper oxide catalysts based on an oxidative thermal treatment copper-containing deep eutectic solvents (DES). XRD EDX analysis samples show that at 500 °C in air prolonged time (60 min) provides exc...

Introduction Gasoline is a complex solution of different hydrocarbons. Naturally occurring petroleum contains aromatic hydrocarbons, a class of unsaturated hydrocarbons that includes benzene, toluene, ethylenzene, and xylene (collectively known as BTEX). Since the EPA banned lead additions to gas in 1973, aromatic hydrocarbons were added to increase the octane concentration, thereby maximizing ...

NK cells are regulated by inhibiting and activating cell surface receptors. Most inhibitory receptors recognize MHC class I Ags and protect healthy cells from NK cell-mediated autoaggression. However, certain activating receptors, including the human activating killer cell Ig-like receptor (KIR) 2DS1, also recognize MHC class I. This fact raises the question of how NK cells expressing such acti...

Petroleum exploitation in oilfields, especially drilling, generates an oily sludge mixed with hydrocarbons and mineral solids. This oily sludge is sometimes treated by bioremediation and phytoremediation. This investigation established that landfarmed oil sludge provided adequate soil conditions to grow jack beans (Canavalia ensiformis) that in turn rhizoand phytoremediated residual aliphatic a...

The C2 domain is a membrane-targeting domain found in many cellular proteins involved in signal transduction or membrane trafficking. The majority of C2 domains co-ordinate multiple Ca(2+) ions and bind the membrane in a Ca(2+)-dependent manner. To understand the mechanisms by which Ca(2+) mediates the membrane binding of C2 domains, we measured the membrane binding of the C2 domains of group I...

Aryl hydroxylase, derived from hamster fetus cells grown in culture, is an inducible microsomal enzyme system which requires NADPH and molecular oxygen. The addition of benz[u]anthracene or other polycyclic hydrocarbons to the culture medium causes significant increases in the amount of hydroxylase activity: after a lag period of 35 min, the level of hydroxylase activity increases linearly for ...

The articles [9], [1], [3], [4], [6], [5], [2], [7], and [8] provide the notation and terminology for this paper. We use the following convention: q, r, c, c1, c2, c3 are quaternion numbers and x1, x2, x3, x4, y1, y2, y3, y4 are elements of R. 0H is an element of H. 1H is an element of H. Next we state several propositions: (1) For all real numbers x, y, z, w holds 〈x, y, z, w〉H = x+y · i+ z · ...

solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. therefore,...
