Suppose I and J are proper ideals on some set X. We say that incompatible if I∪J does not generate a ideal. Equivalently, there is A⊆X such A∈I X∖A∈J. If B⊆X either in I∖J or J∖I, then we B chooses between J. consider the following Ramsey-theoretic problem: Given several pairs (I1,J1),(I2,J2),…,(Ik,Jk) of X, find as many these possible. The main theorem for every n∈N, I(n)∈N given at least I(n)...

A month-old baby girl with blood type O positive received a donor heart organ from a donor with blood type B. This was the first institutional ABO-incompatible heart transplant. Infants listed for transplantation may be considered for an ABO-incompatible heart transplant based on their antibody levels and age. The United Network of Organ Sharing (UNOS) protocol is infants under 24 months with t...

BACKGROUND Current guidelines recommend the use of Escherichia coli (EC) or thermotolerant ("fecal") coliforms (FC) as indicators of fecal contamination in drinking water. Despite their broad use as measures of water quality, there remains limited evidence for an association between EC or FC and diarrheal illness: a previous review found no evidence for a link between diarrhea and these indicat...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...

Global positioning systems (GPSs) and geographical information systems (GISs) have been widely used to collect and synthesize spatial data from a variety of sources. New advances in satellite imagery and remote sensing now permit scientists to access spatial data at several different resolutions. The Internet facilitates fast and easy data acquisition. In any one study, several different types ...

Let M be a countable model of ZF~ . There exists a family & of 2 models of ZF each obtained from M by adjoining an A/-generic family of 2W Cohen reals, such that no two distinct models in !F have a common extension to a model of ZF~ with the same ordinals.

ABO antigens are composed of sugar chains and exist not only on red cells but also on many other cells including endothelial cells and epithelial cells of various organs such as kidney, heart, bowel, lung, and pancreas (Marionneau et al., 2001). ABO antibodies, which have been called as isoagglutinins, are preformed antibodies directed against missing A or B antigens. The source of anti-A/B ant...

Bangladesh is underlain by shallow aquifers in which millions of drinking water wells are emplaced without annular seals. Fecal contamination has been widely detected in private tubewells. To evaluate the impact of well construction on microbial water quality 35 private tubewells (11 with intact cement platforms, 19 without) and 17 monitoring wells (11 with the annulus sealed with cement, six u...

OBJECTIVE To determine how data on water source quality affect assessments of progress towards the 2015 Millennium Development Goal (MDG) target on access to safe drinking-water. METHODS Data from five countries on whether drinking-water sources complied with World Health Organization water quality guidelines on contamination with thermotolerant coliform bacteria, arsenic, fluoride and nitrat...
