The Homrit Akarem granitic intrusion (HAGI) outcrops near the western edge of south Eastern Desert basement exposure in Egypt. It is a composite two cogenetic intrusive bodies: an early albite granite phase shallowly emplaced at apex magmatic cupola, and later subjacent pink with marginal zone muscovite better preservation features. Mineral chemistry primary biotite garnet, together whole-rock ...

In 1888, James Joseph Sylvester (1814-1897) published a series of papers that he hoped would pave the way for a general proof of the nonexistence of an odd perfect number (OPN). Seemingly unaware that more than fifty years earlier Benjamin Peirce had proved that an odd perfect number must have at least four distinct prime divisors, Sylvester began his fundamental assault on the problem by estab...

Holocene changes in terrestrial provenance and processes of sediment transport and deposition are tracked along a fjord-to-shelf transect adjacent to Vestfirdir, Iceland, using the magnetic properties ofmarine sediments.Magnetic susceptibility (MS) profiles of 10 cores (gravity and piston) were obtained onboard using a Bartington MS loop. Remanent magnetizations were measured at 1-cm intervals ...

BACKGROUND Atelectasis is a major cause of hypoxemia after coronary artery bypass grafting (CABG) and is commonly ascribed to general anesthesia, high inspiratory oxygen concentration and cardiopulmonary bypass (CPB). The objective of this study was to evaluate the role of heart-induced pulmonary compression after CABG with CPB. METHODS Seventeen patients without pre-operative cardiac failure...

As would be expected, the lesion is recognized in young to early middle life. The patient tends to be frail rather than robust, though there are exceptions to this, and there is no physical retardation. Clubbing of the fingers is frequently present, and telangiectases or hemangiomata may be present in the skin or mucous membranes. The most common presenting symptoms are cyanosis, which sometime...

The Ochtiná Aragonite Cave (Western Carpathians) represents an unique natural phenomenon. It originated under particular lithological and hydrogeological conditions of the Karst in which several isolated lenses Paleozoic crystalline limestone (marbles), partly metasomatically altered to ankerite, are enclosed by phyllites. Meteoric water seepage through non-carbonate rocks dissolved caused oxid...

Spectroscopic and photometric observations of the star Parenago 1540 (V = 11.3), located 10 arcmin west of the Trapezium in Orion, have shown the star to be a pre-main-sequence double-lined spectroscopic binary. Thirty-seven radial-velocity measurements were obtained from which the orbital elements of the binary were determined, in particular an orbital period P = 33.73 + 0.03 days and an eccen...

tuffs do not result from pyroclastic flow and hence are not true pyroclastic flow deposits. They do not explain the processes they envision, but in this situation pyroclastic emplacement without some form of lateral flow is clearly impossible, even in near-vent locations. 18. M. J. Branney and R. S. J. Sparks, J. Geol. Soc. London 147, 919 (1990). 19. For example, halloysite, smectites, sericit...

There is a well-known formula due to Andrews that counts the number of incongruent triangles with integer sides and a fixed perimeter. In this note, we consider the analagous question counting the number of k-tuples of nonnegative integers none of which is more than 1/(k−1) of the sum of all the integers. We give an explicit function for the generating function which counts these k-tuples in th...
