Alkaline saline soils, known also as "soda solonchaks", represent a natural soda habitat which differs from soda lake sediments by higher aeration and lower humidity. The microbiology of soda soils, in contrast to the more intensively studied soda lakes, remains poorly explored. In this work we investigate the diversity of culturable aerobic haloalkalitolerant bacteria with various hydrolytic a...

Drinking too much of the bubbly? It?s not clear if you?re a regular or diet soda drinker, but regular soda is a source of sugar, caffeine, sometimes coloring, and little else. One twelveounce can of regular soda typically contains eight teaspoons of sugar and 130 calories ? but zero nutritional content. The American Heart Association [2] recommends that individuals assigned male at birth limit ...

This report describes the isolation, sequencing, and functional analysis of the sodA gene, encoding Mn-superoxide dismutase, from Streptococcus thermophilus AO54. The gene was found to encode a 201 amino acid polypeptide with 88 and 83% identity to SodA from Streptococcus mutans and Streptococcus agalacticae, respectively. Primer extension analysis revealed a transcriptional start site 27 nucle...

OBJECTIVE To evaluate and compare the effectiveness in reducing plaque of a fluoride dentifrice containing baking soda and a non-baking soda fluoride dentifrice containing an antimicrobial (triclosan/copolymer) system after a single brushing and over a four-week period of daily brushing. METHODS A total of 207 subjects completed this randomized, blinded, parallel-group clinical study. Twenty-...

In a recent breakthrough, Paz and Schwartzman [SODA’17] presented a single-pass (2 + ε)approximation algorithm for the maximum weight matching problem in the semi-streaming model. Their algorithm uses O(n log n) bits of space, for any constant ε > 0. In this note, we present a different analysis, for essentially the same algorithm, that improves the space complexity to the optimal bound of O(n ...

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because expectations of a possibly binding bound in the future amplify the e ects of adverse shocks. Calibrating the mod...

In this paper, we study the 3D strip packing problem in which we are given a list of 3dimensional boxes and required to pack all of them into a 3-dimensional strip with length 1 and width 1 and unlimited height to minimize the height used. Our results are below: i) we give an approximation algorithm with asymptotic worst-case ratio 1.69103, which improves the previous best bound of 2 + ǫ by Jan...
