Furrow irrigation detaches and transports soil particles and subsequently nutrients such as phosphorus (P). To reduce the risk of erosion and offsite P movement, producers can convert from furrow to sprinkler irrigation. We completed research on soil P dynamics in furrow versus sprinkler irrigated soils from four paired fields in south central Idaho. Surface soils (0-2.5 inches) were obtained f...

up to now, interactions between method and amount of nitrogen fertilizers application on plant density and variety of wheat under sprinkler irrigation systems have not been studied. thus, this research was conducted during two years in esfehan region with split factorial design. the treatments of this experiment were: three fertilizers application methods (conventional manual application at the...

Fire test data of boats in rack storage are needed to establish more specific requirements for fire control and protection for this type of vessel in high piled rack storage configurations. Since there is no current large or full scale fire test data available, we have embarked upon testing fire and thermal properties of boat material, fiber reinforced polymer (FRP) composite, by using Differen...

Chirality is not just a structural artifact in biology but it may provide for a genuine biological advantage. This is due to the phenomenon of chiral interaction (CI) which is described here for mechanical-chiral devices. The main mechanical feature of chiral interaction is its mode of selecting one direction of rotation out of two possible and opposite ones. For example, a given chiral device ...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study the infiltration parameters were evaluated in real conditions of a center pivot system. for this purpose a single ring with ...

This paper discusses the experimental set-up and procedures for the seismic testing and evaluation of a sprinkler system in hospital model. Concrete compression tests are ran to ensure compliance with ACI 355.2 anchor testing qualifications. Maximum shear strength of the anchor is found to include within the piping system model. Frame and piping system within the model is tested under input mot...

The main objective of this study is to compare the results in terms gas temperature and structural elements temperature, using different localized fire models. In particular, with reference an open car park fire, simplified Hasemi model was firstly used for assessing steel a typological steel-concrete beam. second step, computational fluid dynamics (CFD) models were applied, also varying geomet...
