Objective: Class B carbapenemases are bacterial enzymes that catalyze the hydrolysis of β-lactam core antibiotics, except for monobactams. The objective this study was to identify carbapenemase gene blaIMP in genus Klebsiella at Charles De Gaulle Pediatric University Hospital (CHUP-CDG) Ouagadougou, Burkina Faso. Methods: involved 17 strains responsible human infection and isolated from various...

Abstract. The nitrogen-15 (15N) natural abundance composition (δ15N) in soils or plants is a useful tool to indicate the openness of ecosystem N cycling. This study aimed evaluate influence experimental warming on soil and plant δ15N. We applied global meta-analysis method synthesize 79 76 paired observations δ15N from 20 published studies, respectively. Results showed that mean effect sizes un...

Abstract. We present speleothem fluid inclusion ?18Of and ?2Hf values from Larga Cave, Puerto Rico, that cover the interval between 46.2 15.3 ka on millennial scale, including Last Glacial Maximum (LGM) several stadial interstadial cycles. The data set can be divided in two main clusters of stable isotope compositions water with respect to global meteoric line (GMWL), which coincide strong vari...

Annona muricata L. and squamosa are tropical species whose fleshy fruit is edible. They offer real possibilities for socio-economic use, particularly in the fields of medicine, nutrition, ecosystem conservation poverty alleviation. This study was set up to evaluate different methods micropropagation from juvenile material regeneration these species. Thus, MS medium supplemented with [BAP 2 mg·L...

The sparse phase retrieval aims to recover the signal from quadratic measurements. However, measurements are often affected by outliers and asymmetric distribution noise. This paper introduces a novel method that combines quantile regression L1/2-regularizer. It is non-convex, non-smooth, non-Lipschitz optimization problem. We propose an efficient algorithm based on Alternating Direction Method...

The mechanism of experimentally observed high-temperature superconductivity (HTSC) in thin FeSe films on SrTiO3-type substrates has been theoretically investigated. Applying the theory large-radius bipolaronic states developed based exact Hamiltonian electron-phonon interaction for arbitrary multilayer structures, Cooper pairing polarons monolayers SrTiO3 is investigated a...

Abstract. We report measurements of atmospheric C3H8 from analysis ground-based solar absorption spectra the Jet Propulsion Laboratory (JPL) MkIV interferometer. Using strong Q-branch feature at 2967 cm?1, we can measure in locations where its abundance is enhanced by proximity to sources (e.g., large natural gas fields, megacities). A case study Fort Sumner, New Mexico, shows that amounts are ...

Along with the popularity of environmental protection concepts, treatment water pollution attracts widespread attention, among which, research on Bi-based semiconductor photocatalytic degradation technology has made great progress. However, development such bismuth-based composites still remains a challenging task due to difficult recovery and low catalytic efficiency. Herein, novel CC/BiPO4/Bi...

Abstract. Measurements of the pollution trace gases ethane (C2H6), ethyne (C2H2), formic acid (HCOOH), and peroxyacetyl nitrate (PAN) were performed in North Atlantic upper troposphere lowermost stratosphere (UTLS) region with airborne limb imager GLORIA (Gimballed Limb Observer for Radiance Imaging Atmosphere) high spatial resolution down to cloud top. Observations made during flights German r...

Abstract. Soil evaporation is a key process in the water cycle and can be conveniently quantified using ?2H ?18O bulk surface soil (BW). However, recent research shows that larger pores evaporates first differs from smaller ?18O, which disqualifies quantification of BW ?18O. We hypothesized had different isotopic compositions evaporating (EW). Therefore, our objectives were to test this hypothe...
