Three groups of five rumen and duodenum cannulated fauna-free sheep were used in a 28 d experiment. One group remained fauna-free, whereas the second (EN) and third (PP) groups, respectively, were inoculated intraruminally with the protozoan species Entodinium caudatum and Polyplastron multivesiculatum. Rumen fluid, duodenal digesta and faecal samples were collected during the last 12 d. The fl...

The rate of substitution of aqua ligands by three nucleophiles, thiourea (TU), N,N-dimethylthiourea (DMTU) and N,N,N,N-tetramethylthiourea (TMTU), for the complexes [cis-{PtOH2(NH3)2}2-μ-pyrazine](ClO4)2 (pzn), [cis-{PtOH2(NH3)2}2-μ-2,3-dimethylpyrazine](ClO4)2 (2,3pzn), [cis-{PtOH2(NH3)2}2-μ-2,5-pyrazine](ClO4)2 (2,5pzn) and [cis-{PtOH2(NH3)2}2-μ-2,6-dimethylpyrazine](ClO4)2 (2,6pzn) was inves...

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...

Accurate estimates of ammonia (NH3) emissions are needed for reliable predictions of fine particulate matter (PM2.5) by air quality models (AQMs), but the current estimates contain large uncertainties in the temporal and spatial distributions of NH3 emissions. In this study, the US EPA Community Multiscale Air Quality (CMAQ) modeling system is applied to study the contributions of the agricultu...

this experiment was conducted to assess the effects of daytime cutting management (p.m. vs. a.m. cut), ensiling duration and adding microbial inoculants on chemical composition of alfalfa silage. for this, second growth alfalfa harvested at the early bud stage of development after a sunny day at sundown (about 1900 h; pm alfalfa), whereas the second half was cut next day at sunup (about 0800 h;...

Bifunctional neutral half-sandwich RuII complexes of the type [(η6-arene)Ru(NH3)Cl2] where arene is p-cym (1) or bip (2) were synthesised by the reaction of N,N-dimethylbenzylamine (dmba), NH4PF6 and the corresponding RuII arene dimer, and were fully characterised. X-ray crystallographic studies of [(η6-p-cym)Ru(NH3)Cl2]·{(dmba-H)(PF6)} (1a) and [(η6-bip)Ru(NH3)Cl2] (2) show extensive H-bond in...

We present measurements of ammonia (NH3) over a deciduous forest in southern Indiana collected during four field campaigns; two in the spring during the transition to leaf-out and two during the winter. Above canopy NH3 concentrations measured continuously using two Wet Effluent Diffusion Denuders indicate mean concentrations of 0.6– 1.2mgm 3 during the spring and 0.3mgm 3 during the winter. Me...

This study was carried out to investigate the effects of treated protein supplements with tannin extracted from pistachio by-product (P-PB) on in vitro gas production using fistulated sheep. One portion of P-PB was mixed with four portions of water for 48 h. The extracted product was sprayed on soybean meal (SBM) or canola meal (CM) with an equal ratio (1:1 v/w) and dried in the shade. The expe...

To our knowledge, no study investigating the usefulness of cardiac PET for detection of myocardial involvement of sarcoidosis is available. We investigated whether N-NH3/F-FDG PET could identify cardiac involvement in patients with sarcoidosis. Methods: Seventeen patients with cardiac sarcoidosis underwent cardiac N-NH3/F-FDG PET under fasting condition. Systemic sarcoidosis was diagnosed by hi...

Studies show that agricultural and animal feeding operations (AFOs) contribute a considerable amount of ammonia (NH3) to the atmosphere. Agricultural NH3 emissions are recognized as an important air quality issue. Biological decomposition of manure from dairy operations results in emissions of NH3 and other gases. There is a need to determine NH3 emission factors (EFs) to compile annual NH3 inv...
