The thermal oxidation of propane in the temperature range 350-425oC was studied in order to elucidate the role of higher aldehydes as degenerate branching intermediates in the oxidation of hydrocarbons. In the slow combustion of propane, the high yield of propylene and methanol as the primary products, the formation of hydrogen peroxide, carbon monoxide, carbon dioxide, formaldehyde and steam a...

Neuron branching patterns can characterize neural cell types and act as markers for neurodegenerative disease and neural development. We develop a hybrid Markovian model for neural branching that extends previously published models by (i) using a discretized gamma model to account for underdispersion in primary branching, (ii) incorporating both bifurcation and trifurcation branching events to ...

in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...

The tracheal (respiratory) system of Drosophila melanogaster is a branched network of epithelial tubes that ramifies throughout the body and transports oxygen to the tissues. It forms by a series of sequential branching events in each hemisegment from T2 to A8. Here we present a cellular and initial genetic analysis of the branching process. We show that although branching is sequential it is n...

Slit is a secreted protein known to repulse the growth cones of commissural neurons. By contrast, Slit also promotes elongation and branching of axons of sensory neurons. The reason why different neurons respond to Slit in different ways is largely unknown. Islet2 is a LIM/homeodomain-type transcription factor that specifically regulates elongation and branching of the peripheral axons of the p...

Interstitial branches arise from the axon shaft, sometimes at great distances behind the primary growth cone. After a waiting period that can last for days after extension of the primary growth cone past the target, branches elongate toward their targets. Delayed interstitial branching is an important but little understood mechanism for target innervation in the developing CNS of vertebrates. O...

This paper shows that, even at the most basic level (namely, in combination with only ¬,∧,∨), the parallel, countable branching and uncountable branching recurrences of computability logic validate different principles. MSC: primary: 03B47; secondary: 03B70; 68Q10; 68T27; 68T15.

The mammalian lung, like many other organs, develops by branching morphogenesis of an epithelium [1]. Development initiates with evagination of two ventral buds of foregut endoderm into the underlying splanchnic mesoderm. As the buds extend, they send out lateral branches at precise, invariant positions, establishing the primary airways and the lobes of each lung. Dichotomous branching leads to...
