We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant dipole trap. The mixture is prepared with a new technique that applies to intermediate and heavy alkaline earth like atoms. In this work, Sr and Sr are simultaneously loaded first into the magneto-optical trap operate...

We compute the dynamic structure factors of a dense binary liquid mixture. These describe dynamics on molecular length scales, where structural relaxation is important. We find that the presence of a few large particles in a dense fluid of small particles slows down the dynamics considerably. We also observe a deep narrowing of the spectrum for a disordered mixture composed of a nearly equal pa...

For a mixture of interacting Bose gases initially prepared in regime condensation (uncorrelation), it is proved that the course time evolution observables disjoint sets particles each species have correlation functions remain asymptotically small total number and display controlled growth time. This obtained by means ad hoc estimates Lieb–Robinson type on propagation interaction, established he...

Background and Purpose: Pistacia atlantica, which belongs to the Anacardiaceae family, grows in the Zagrossian region of Iran. The aim of this study was to evaluate the antifungal properties of Pistacia atlantica and olive leaf extracts against different fungal species. Materials and Methods: In this study, we assessed the activities of olive leaf extracts and Pistacia atlantica leaf and fruit...

Copolymerisation of carbenes and olefins (ethene), mediated by Rh-based catalyst precursors, is presented as a new, proof-of-concept methodology for the controlled synthesis of functional polymers. The reactions studied show that olefin-carbene polymerisation reactions provide a viable alternative to more traditional olefin polymerization techniques. Rh(III)-catalyst precursors, while active in...

Highly purified trachoma elementary bodies (T'ang strain), incubated in the presence of the four nucleoside triphosphates [Mg(2+), Mn(2+), 2-mercaptoethanol, tris(hydroxymethyl)aminomethane buffer (pH 7.5)] were found to incorporate (3)H-uridine triphosphate (UTP) into ribonucleic acid (RNA) molecules. Eighty-seven per cent of the labeled molecules were sensitive to ribonuclease treatment. In v...

The purpose of the present study was to determine the tropane alkaloid content of four Hyoscyamus species from Iran, i.e. H. pusillus L., H. niger L., H. reticulatus L. and H. kurdicus Bornm. Determination of alkaloids was performed by the HPLC method. Samples were extracted with chloroform-methanol-25% ammonium hydroxide 15:5:1 (V/V/V). HPLC separation was performed on Eurospher C18 reversed p...

Timely and accurate biodiversity analysis poses an ongoing challenge for the success of biomonitoring programs. Morphology-based identification of bioindicator taxa is time consuming, and rarely supports species-level resolution especially for immature life stages. Much work has been done in the past decade to develop alternative approaches for biodiversity analysis using DNA sequence-based app...

DNA samples are often pooled, either by experimental design or because the sample itself is a mixture. For example, when population allele frequencies are of primary interest, individual samples may be pooled together to lower the cost of sequencing. Alternatively, the sample itself may be a mixture of multiple species or strains (e.g., bacterial species comprising a microbiome or pathogen stra...
