Pengaruh Lama Fermentasi Tepung Kulit Pisang Menggunakan Saccharomyces Cerevisiae terhadap Konsentrasi VFA, N-NH3 dan pH In vitro

open access: yesJurnal Peternakan Lahan Kering, 2022
 This study aims to determine the effect of banana skin fermentation time using yeast Saccharomyces cerevisiae on concentration of VFA, N-NH3 and pH of rumen fluid in vitro. The method used in this study is an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications.

Infrared Dark Clouds in the Small Magellanic Cloud? [PDF]

open access: yes, 2009
We have applied the unsharp-masking technique to the 24 $\mu$m image of the Small Magellanic Cloud (SMC), obtained with the Spitzer Space Telescope, to search for high-extinction regions.

Plant uptake of nitrogen adsorbed to biochars made from dairy manure

open access: yesScientific Reports, 2021
The conversion of dairy waste with high moisture contents to dry fertilizers may reduce environmental degradation while lowering crop production costs. We converted the solid portion of screw-pressed dairy manure into a sorbent for volatile ammonia (NH3)

Significant reduction of ammonia emissions while increasing crop yields using the 4R nutrient stewardship in an intensive cropping system

open access: yesJournal of Integrative Agriculture, 2023
Ammonia (NH3) emissions should be mitigated to improve environmental quality. Croplands are one of the largest NH3 sources, they must be managed properly to reduce their emissions while achieving the target yields.

The influence of long term trends in pollutant emissions on deposition of sulphur and nitrogen and exceedance of critical loads in the United Kingdom [PDF]

open access: yes, 2009
In the United Kingdom, as with other European countries, land-based emissions of NOX and SO2 have fallen significantly over the last few decades. SO2 emissions fell from a peak of 3185 Gg S in 1970 to 344 Gg S in 2005 and are forecast by business-as ...

Effect of source and level of forage in the diet on in vitro ammonia emission from manure of Holstein and Jersey dairy cows

open access: yesJDS Communications, 2021
Reducing overall reactive N losses from dairy production systems depends substantially on reducing the atmospheric emission of manure ammonia (NH3). The objective of this study was to determine potential NH3-N emission of reconstituted manure using an in

Chemical Variation in Molecular Cloud Cores in the Orion A Cloud

open access: yes, 2010
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the first time.

The NH2D/NH3 ratio toward pre-protostellar cores around the UCHII region in IRAS 20293+3952 [PDF]

open access: yes, 2010
The deuterium fractionation, Dfrac, has been proposed as an evolutionary indicator in pre-protostellar and protostellar cores of low-mass star-forming regions. We investigate Dfrac, with high angular resolution, in the cluster environment surrounding the

Land Cover and Water Quality Patterns in an Urban River: A Case Study of River Medlock, Greater Manchester, UK [PDF]

open access: yes, 2020
Urban river catchments face multiple water quality challenges that threaten the biodiversity of riverine habitats and the flow of ecosystem services. We examined two water quality challenges, runoff from increasingly impervious land covers and effluent ...

Volatilização de N-NH3 na cultura de milho: I. efeito da irrigação e substituição parcial da uréia por sulfato de amônio [PDF]

open access: yesRevista Brasileira de Ciência do Solo, 1997
Foi desenvolvido um experimento em latossolo vermelho-escuro muito argiloso fase cerrado, no Centro de Pesquisas Novartis-Seeds, Uberlândia (MG), para avaliar o efeito da irrigação e do N-uréia, em cobertura no milho, e de sua substituição parcial por sulfato de amônio, nas perdas de N-NH3 volatilizado.
