The molecular structure describes a square of Ln(III) ions housed within a square of Mn(III) ions. Magnetic studies reveal that 1 has a large number of molecular spin states that are populated even at the lowest investigated temperatures, while the ferromagnetic limit S = 22 is being approached only at the highest applied fields. This, combined with the high magnetic isotropy, makes the complex an excellent magnetic refrigerant for low-temperature applications. Replacement of the isotropic Gd(III) ions with the anisotropic Tb(III) and Dy(III) ions "switches" the magnetic properties of the cluster so that 2 and 3 behave as low-temperature molecular magnets, displaying slow relaxation of the magnetization.

For each of those stars its PMSU number, identifier, distance, TiO5 spectral index, equivalent width of the Halpha line (EW Halpha) if active, K band magnitude and absolute bolometric magnitude are listed. The final remark indicates if the star has been excluded from the sample of single main sequence stars. (2 data files).

&... more 'Candidatus Rickettsia amblyommii' is a spotted fever group rickettsia that is not considered pathogenic, although there is serologic evidence of possible infection in animals and humans. The aim of this study was to evaluate the pathogenic potential of a Costa Rican strain of 'Candidatus R. amblyommii' in guinea pigs and determine its capacity to generate protective immunity against a subsequent infection with a local strain of Rickettsia rickettsii isolated from a human case. Six guinea pigs were inoculated with 'Candidatus R. amblyommii' strain 9-CC-3-1 and two controls with cell culture medium. Health status was evaluated, and necropsies were executed at days 2, 4, and 13. Blood and tissues were processed by PCR to detect the gltA gene, and end titers of…

Two closely linked Y chromosome markers, TSPY and SRY, were sequenced for a total of 3100 bases. Forty-four macaques, representing 18 of the 19 recognized species, were sequenced for the full 3.1 kb, as was 1 individual from each of the following outgroup genera: Papio, Theropithecus, Mandrillus, Allenopithecus,Cercopithecus, Trachypithecus, Presbytis, and Homo. In contrast to recent mtDNA phylogenies, Y chromosome loci support four monophyletic species groups, including a sinica group containing M. arctoides-a classification largely congruent with those of Fooden and Delson. Comparison of mtDNA and Y chromosome phylogenies highlight (1) a potential hybrid origin of Macaca arctoides from M. fascicularis and proto-M. assamensis/thibetana and (2) cases of mitochondrial paraphyly in macaque species whose Y chromosome l...

We sequenced the hypervariable region I (HV-I) of the mitochondrial D-loop to reconstruct the phylogeny of this group. Although the results clearly supported monophyly of each of the six species, the relationships among them were not clearly resolved by these data alone. A homogeneity test against published data sets of a coding mitochondrial locus (ND3-ND4 region), behavioral characters (vocalizations), and morphological traits (including skeletal and soft tissue anatomy) revealed no significant incongruence, and combining them resulted in a phylogenetic tree with much stronger support. The Kloss's gibbon (H. klossii), long considered a primitive taxon based on morphology, shares many molecular and vocal characteristics with the Javan gibbon (H. moloch), and appear as the most recently derived species. The northernmost species (H. lar and H. pileatus) ar...

Recently, sea-level monitoring and climate change studies generated great interest as well as for its regional oceanography. A plethora of observations has convincingly demonstrated the importance of the area for regional meteorological and climatologic changes affecting Eurasia and North Africa.
