We analyze the structure and morphology of mesocrystalline, body-centered tetragonal (bct) superlattices of PbS nanocrystals functionalized with oleic acid. On the basis of combined scattering and real space imaging, we derive a three-dimensional (3D) model of the superlattice and show that the bct structure benefits from a balanced combination of {100}PbS-{100}PbS and {111}PbS-{111}PbS interac...

Antiferromagnetic interlayer coupling between ferromagnetic layers of EuS via nonmagnetic PbS spacer layer was experimentally studied in EuS– PbS wedge multilayers grown on KCl (001) substrates with EuS thickness of 6 nm and PbS thickness varying in the wedges in the range 0.3–6 nm (i.e. n = 1−20 monolayers). Measurements of magnetic hysteresis loops of EuS–PbS multilayers performed in the temp...

Pulsed femtosecond laser irradiation at low repetition rate, without any annealing, has been used to localize the growth of PbS nanoparticles, for the first time, inside a transparent porous silica matrix prepared by a sol-gel route. Before the irradiation, the porous silica host has been soaked within a solution containing PbS precursors. The effect of the incident laser power on the particle ...

PURPOSE To investigate Pediatric Balance Scale (PBS) performance in children developing typically. METHODS The PBS was administered to 643 children developing typically per parent report, aged 2 years 4 months to 13 years 7 months. RESULTS A 2-way analysis of variance and post hoc analyses identified significant age and gender differences in PBS performance. The Spearman rank correlation an...

Pear black spot (PBS) disease, which is caused by Alternaria alternata (Aa), is one of the most serious diseases affecting sand pear (Pyrus pyrifolia Nakai) cultivation worldwide. To investigate the defense mechanisms of sand pear in response to Aa, the transcriptome of a sand pear germplasm with differential resistance to Aa was analyzed using Illumina paired-end sequencing. Four libraries der...

Protective behavioral strategy (PBS) use is associated with less alcohol consumption and fewer alcohol-related problems. Further, greater endorsement of social or enhancement drinking motives (i.e., positive motives) is associated with less frequent PBS use. Limited research has, however, explored coping or conformity motives (i.e., negative motives) in relation to PBS. Consequently, the presen...

Within the Pumwani sex worker cohort, a subgroup remains seronegative, despite frequent exposure to HIV-1; some of them seroconverted several years later. This study attempts to identify viral variations in 5'LTR-leader sequences (5'LTR-LS) that might contribute to the late seroconversion. The 5'LTR-LS contains sites essential for replication and genome packaging, viz, primer binding site (PBS)...

The current "Pharmaceutical Benefits Scheme (PBS) community awareness campaign" explicitly links the difficulties facing the PBS to patient behaviour and "waste". The campaign suggests that patients are taking advantage of affordable access to prescription medicines, and emphasises that patient responsibility is "the prescription for a healthy PBS". By neglecting to inform the public that the p...

Exponentially growing Chinese hamster V79 cells were exposed to Adriamycin either in phosphate buffered saline (PBS) or fresh growth medium (F-med) supplemented with various amounts of NaCl in the range between 50-1000 mM and survival was measured by the colony forming assay. Compared to the survival obtained after exposure of cells to isotonic (140 mM NaCl) PBS (D0 = 0.16 microgram/ml, Dq = 0....

ÖZET Animal Models For Interstitial Cystitis/Painful Bladder Syndrome The International Continence Society has defined IC/PBS as “the complaint of suprapubic pain related to bladder filling, accompanied by other symptoms such as increased daytime and night-time frequency, in the absence of proven urinary infection or other obvious pathology” (1). IC is a chronic inflammation of the urinary blad...
