Alfalfa was harvested as second-cutting regrowth herbage, ensiled either at low DM (direct-cut) or high DM (wilted), untreated or treated with .82 or .66% anhydrous NH3 (percentage of DM), respectively, and offered to four Holstein heifers. Silages low in DM had more gross energy and more NDF in DM than silages high in DM. Ammonia treatment increased total, soluble, rumen-insoluble, and NH3 N f...

We present infrared spectra of four embedded protostars in the 750-1230 cm-1 (13.3-8.1 microns) range. For NGC 7538 IRS 9, a new band is reported at 1110 cm-1 (9.01 microns, and several others may be present near 785, 820, 900, 1030, and 1075 cm-1 (12.7, 12.2, 11.1, 9.71, and 9.30 microns). The band 1110 cm-1 is attributed to frozen NH3. Its position and width imply that the NH3 is frozen in...

To investigate the effect of ammonia (NH3) and humidity on the immune response of broilers, broilers were exposed to 30 or 70 mg/kg atmospheric NH3 for 21 days. Additionally, birds were exposed to 35, 60, and 85% relative humidity (RH). The relative weights of lymphoid organs, serum total protein, serum globulin, serum albumin, serum lysozyme, proliferation index of peripheral blood lymphocytes...

We describe the synthesis and characterisation of open fullerene (1) and its reduced form (2) in which CH4 and NH3 are encapsulated, respectively. The 1 H NMR resonance of endohedral NH3 is broadened by scalar coupling to the quadrupolar 14 N nucleus, which relaxes rapidly. This broadening is absent for small satellite peaks, which are attributed to natural abundance 15 N. The influence of the ...

Non-expresser of pathogenesis-related genes 1 (NPR1) is the master regulator of salicylic acid-mediated systemic acquired resistance. Over-expression of Arabidopsis NPR1 and rice NH1 (NPR1 homolog1)/OsNPR1 in rice results in enhanced resistance. While there are four rice NPR1 paralogs in the rice genome, none have been demonstrated to function in disease resistance. To study rice NPR1 paralog 3...

Determining the interaction and solvation structure of molecules with solvents near a surface is of fundamental importance for understanding electroand photochemical processes. Here we used scanning tunneling microscopy (STM) to investigate the adsorption and solvation structure of ammonia on water monolayers on Pt(111). We found that at low coverage NH3 binds preferentially to H2O molecules th...

The present work is focused on the effect of water NH3 adsorption over Cu-CHA SCR catalysts. For this purpose, samples characterized by different SAR (SiO2/Al2O3) ratios and Cu loadings were studied under both dry wet conditions. H2O adversely affects Lewis acid sites (Cu ions) all tested catalysts, as indicated decreased desorption at low temperature during TPD. Interestingly, NH3/Cu ratio, he...

The resistance of the perovskite CH3NH3PbI3 film was found to decrease significantly in seconds when the film was exposed to an NH3 atmosphere at room-temperature, and recover to its original value in seconds when out of the NH3 environment.

Electron capture by the ion H3C–S–S–CH2–CH2–NH3 at either the NH3 site (to form the Rydberg radical H3C–S–S–CH2–CH2–NH3) or into the S–S antibonding * orbital is shown to be able to produce the same S–S bond fragmentation products H3C–S and HS–CH2–CH2–NH2, albeit by very different pathways. Capture into the S–S * orbital is, in the absence of the nearby positive site, endothermic by approximate...

Our study demonstrates that Pt(IV) derivative of cisplatin, with two axial PhB ligands, ctc-[Pt(NH3)2(PhB)2Cl2], is a very potent cytotoxic agent against many different human cancer cell lines and is up to 100 fold more potent than cisplatin, and significantly more potent than the Pt(IV) derivatives of cisplatin with either two hydroxido, two acetato or two valproato ligands. The high potency o...
