Adapting plantlets to ex vitro conditions is a decisive step in the micropropagation process via organogenesis or somatic embryogenesis (ES). The percentage of success this stage determines quality product, an example which found cocoa regenerated by ES, require specific overcome stress new environment. Considering largely survival and growth conditions, effect two culture media between embryo ...

Six bacteria (Bacillus velezensis 13, Bacillus subtillis 42, Pseudomonas fluorescens E221, Poae EE12, Rahnella sp. EM1, and Serratia EM2) isolated from the soil litter of Mexican oak forests were characterized by identifying their ability to acquire phosphorus different sources, analyzed for biocontrol capabilities against two phytopathogenic fungi, finally tested stimulate germination maize se...

Major, trace element, and Nd–Sr–Pb isotopic compositions of mantle xenolith-bearing Cenozoic basalts in southeastern China are measured to provide an insight into the nature of their mantle sources and processes. Application of a modified Ž . dynamic melting inversion DMI method presented here to SE China basalts suggests that Nushan and Fangshan basalts are formed by 4–11% partial melting of a...

Abstract The Transiting Exoplanet Survey Satellite (TESS) has discovered ∼5000 planets and planet candidates after 3.5 yr. With a planned second Extended Mission (EM2) spanning Years 5–7 on the horizon, now is time to revise predictions of TESS exoplanet yield. We present simulations number detectable around 9.4 million AFGKM stars in Candidate Target List v8.01 through 7 yr observations. Our t...

Fjord sediments are increasingly recognized as high-resolution archives of past hydrological and climate variability. Using them such, however, requires a comprehensive understanding the variables that affect their accumulation rates properties. Here, we conduct spatial temporal study sediment samples collected at head Martínez Channel (Chilean Patagonia, 48°S), to understand how fjord's regist...

The mineral dust emitted from Central Asia has a significant influence on the global climate system. However, history and mechanisms of aeolian activity in remain unclear, due to lack well-dated records intense wind erosion some source areas (e.g., deserts). Here, we present sedimentary sequence southern Gurbantunggut Desert China using grain size analysis optically stimulated luminescence (OSL...

[1] An in-depth Sr-Nd-Pb-He-Os isotope and trace element study of the EMII-defining Samoan hot spot lavas leads to a new working hypothesis for the origin of this high Sr/Sr mantle end-member. Systematics of the Samoan fingerprint include (1) increasing Pb/Pb with time from 18.6 at the older, western volcanoes to 19.4 at the present-day hot spot center, Vailulu’u Seamount, (2) en-echelon arrays...

Motivated by recent experimental works on the modifications of endomorphin-2 (EM2, H-Tyr-Pro-Phe-Phe-NH2) to develop better painkiller, we performed structure-activity-relationship (SAR) studies to investigate modified C-terminal ligands by using molecular dynamics (MD) simulations. Specifically, instead of the CONH2 for the unmodified EM2's C-terminus, the analogue 2 with its C-terminus being ...

Measurements were made of a 40 cm ion-thruster plume as part of the single-string-integration-test (SSIT) activity of Phase I of the NASA’s Evolutionary Xenon Thruster (NEXT) project. The NEXT ion engine incorporates design improvements that extend NSTAR power levels and efficiencies. During SSIT, an engineering model (EM2) 40 cm engine was operated using an advanced xenon propellant system in ...
