Human serum antibodies which react different pepsin-digested IgA proteins only with antigenic determinants rewas found in individual sera but no revealed by digestion of IgA with pepsin lationship to either IgA subgroups or were found in 29.2 per cent of the sera genetically determined IgA antigens was from 369 hospitalized patients studied. discerned. The presence of these antiThese antibodies...

One of the first things that any functional programmer learns is how to turn the naive quadratic algorithm for reversing a list into a linear-time algorithm by using an accumulating parameter. In this paper we derive another, quite different, linear-time algorithm for reversing a list. The derivation relies on a higherorder naturality [5] property of the function unzip, the function that turns ...

A collaborative effort between industry and government shows progress towards the goal of identifying productive natural fractures in gas reservoirs using seismic methods. Improved geological understanding of mature gas reservoirs in offshore Gulf of Mexico points towards unrecovered resource. A simple new technique to improve primary cement jobs has resulted in a 36 percent decrease in average...

This review, with 350 references, gives information on the chemical study of 234 naturally occurring tetraoxygenated xanthones in 12 families, 53 genus and 182 species of higher plants, and two which are described as fungal and lichen metabolites. The value of these groups of substances in connection with pharmacological activity and therapeutic use of some species is described. The structural ...

Within the Standard Model, xs (the mixing parameter in theBs−B̄s system) is constrained to the range 7 ≤ xs ≤ 40. We point out that if New Physics contributes significantly to xd (the mixing parameter in the Bd − B̄d system), then 2 ≤ xs ≤ 7 is possible without any fine-tuned cancellations between the Standard Model and the New Physics contributions.

We construct an extension of the MSSM in which scalar superpartners can naturally be as heavy as 1 TeV. In the MSSM, the most significant fine tuning stems from the logarithmically enhanced top-stop loop contribution to the soft Higgs mass. We combine supersymmetry with the “simplest little Higgs” to render this loop finite, thereby removing the large logarithm even in models in which superpart...

in this research, the effect of friction between the liquid metal and the sand mould wall and the effect of passage of liquid through a vertical bend and through a ceramic filter on the fluid flow and the melt velocity has been studied by measuring the velocity of the melt and direct observation of the liquid flow through the different parts of a naturally-pressurized running system. the fricti...

conclusions sperm quality extracted by percutaneous pesa and tese procedures increases fertility outcomes compared to naturally ejaculated sperm in men with idiopathic co. more specifically, embryo quality, which is most relevant to fertility outcome, improved when surgically extracted sperm was used for icsi. results there was a significant difference in fertilization rate, embryo quality, imp...
