    Abstract The irritable bowel syndrome (IBS) is a chronic abdominal symptom complex occurring in a bowel devoid of discernible relevant pathology. There is growing interest in the role of the intestinal microbiota as a basis for the intestinal and possibly behavioral manifestations of this condition. Molecular-based microbial profiling has revealed compositional changes in the microbiota of at least a subset of IBS patients but the data are often conflicting and no microbial signature for this condition has yet been defined. Animal studies in which a previously stable intestinal microbiota is perturbed, by antibiotics or dietary change, results in alterations in intestinal function reminiscent of that seen in IBS patients. These include visceral sensitivity to painful stimuli, altered motility and intestinal barrier function as well as immune activation, and low-grade inflammation. More recent studies have shown that perturbation of the microbial composition of the gut alters brain chemistry and behavior. In a step toward establishing a causal link between an altar microbiota and gut-brain manifestations of IBS, colonization of germ-free mice with microbiota from IBS patients results in an IBS-like phenotype, including alterations and behavior if the donor exhibited psychiatric comorbidity, such as high levels of anxiety. This model provides an opportunity for exploring the mechanisms underlying host-microbe interactions relevant to the pathogenesis of IBS and for developing novel therapeutic targets.

    Abstract High-energy tailing is an often-overlooked component in high-purity germanium gamma-ray spectrometry when performing the non-linear least squares fit of a full-energy peak. This component comes from the incomplete restoration of the baseline prior to the next pulse being processed and therefore is an issue of increased count rates. In the current work, the impact of this oversight is shown through the dynamics and decay characteristics of

    Abstract Formulae are presented for (95)Zr-(95)Nb chronometry of a nuclear event. In particular, they allow for a bias-free calculation of the moment of a nuclear explosion, based solely on a measurement of the produced activity ratio of (95)Zr and (95)Nb in a finite time interval. Also uncertainty propagation factors are presented, which relate the relative uncertainty on the nuclear decay data and activity ratio measurements with the relative uncertainty on the elapsed time. This allows for the calculation of an uncertainty budget, without the need for Monte Carlo simulations. The equations are applied to a set of measurement data and consistency is demonstrated.

    Abstract A new determination of the (109)Cd half-life was made by a time series of measurements of an aqueous sample using a re-entrant type ionisation chamber. The measurement campaign covered a period of 6 years or approximately 4.7 half-lives of (109)Cd. The resulting value of 462.1 (3) days is in good agreement with the recently published values of 462.29 (30) days and 462.3 (8) days. This new half-life determination will allow evaluators to specify a recommended value of the (109)Cd half-life making it more accurate and precise.

    Abstract The radioactive decay half-life of the β(-)-emitter (111)Ag has been measured using decay transitions identified using a high purity germanium γ-ray spectrometer. The time series of measurements of the net peak areas of the 96.8 keV, 245.4 keV and 342.1 keV γ-ray emissions following the β(-) decay of (111)Ag were made over approximately 23 days, i.e. ~3 half-life periods. The measured half-life of the ground state decay of (111)Ag was determined as 7.423 (13) days which is consistent with the Evaluated Nuclear Structure Data File (ENSDF) recommended half-life of 7.45 (1) days at k=2. Utilising all available experimental half-life values, a revised recommended half-life of 7.452 (12) days has been determined.

    Abstract The radioactive half-life of (211)Pb was measured, by α-particle counting of samples of radiochemically pure (211)Pb in equilibrium with its α-emitting progeny, (211)Bi and (211)Po. The samples were prepared by the collection of (215)Po recoil atoms from the decay of the (219)Rn decay progeny produced from a (223)Ra sample onto stainless steel discs. The radioactive decay of the (211)Pb was measured utilising a 2π proportional counter operating on the α plateau. A half-life of 36.164 (13)min was determined, which is in agreement with currently available literature. A full uncertainty budget is presented. A recommended half-life of T1/2((211)Pb)=36.161 (17)min has been evaluated from the current literature values.
