Cyclic nucleotide-gated (CNG) channels are key elements of cGMPand cAMP-signaling pathways in vertebrate photoreceptor cells and in olfactory sensory neurons, respectively. These channels form heterooligomeric complexes composed of at least two distinct subunits ( a and b ). The a subunit of cone photoreceptors is also present in mammalian sperm. Here we identify one short and several long less...

The preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hy...

the present study was conducted to investigate the impacts of retrofitted cng vehicles on airpollutant emissions in tehran over a 20 years period using available statistical data, precise automobile tests, data analysis, and leap software. the obtained results revealed an increase in air pollutant emissionsincluding co (equal to 1030.77 thousand tons), nox (equal to 1030.77 thousand tons), thc ...

Water electrolyzed hydroxyl gas (HHO or Brown gas) and compressed natural (CNG) are the important promising alternatives to pure fossil fuels. The global concern is about GHG emission in environment ambient air pollution steered by mass consumption of fuels automobile industries power sectors. In this study, combustion, performance characteristics HHO CNG mixtures supplied intake manifold compr...

The roles of cyclic nucleotide-gated (CNG) channels in sensory transduction have long been recognized. More recent studies found that CNG channels are distributed in multiple brain regions involved in memory and learning, including the cortex, hippocampus and cerebellum. These findings suggest that their functions are not limited to sensory perception, but also to neuronal plasticity phenomena,...

Compressed natural gas (CNG) and liquefied petroleum (LPG) are included in the group of promoted transport fuel alternatives for traditional fossil fuels Europe. Both CNG LPG fueled vehicles believed to have low particle number mass emissions. Here, we studied solid (SPN) emissions >4 nm, >10 nm >23 bi-fuel applying CNG, gasoline laboratory at 23 °C sub-zero (−7 °C) ambient temperature...

Olfactory masking has been used to erase the unpleasant sensation in human cultures for a long period of history. Here, we show a positive correlation between the human masking and the odorant suppression of the transduction current through the cyclic nucleotide-gated (CNG) and Ca2+-activated Cl- (Cl(Ca)) channels. Channels in the olfactory cilia were activated with the cytoplasmic photolysis o...

In this paper, nonlinear dynamical black-box models of a common rail injection system for a CNG engine are developed. In particular, the common rail pressure dynamics is modeled on the basis of three input signals, easily and cheaply measurable on board a vehicle. The nonlinear model is identified by means of Multi Layer Perceptron neural networks. Both non-autoregressive (NMAX) and autoregress...
