Entropic model application to identify cross-sectional flow effect on velocity distribution in a large amplitude meandering channel
2020
Abstract Literature shows the application of the entropy concept in open channels flow. No existing research has been addressed to the application of the entropy concept for evaluating the effect of secondary flow which especially develops in curved channels. The purpose of this paper is to explore the possibility to evaluate the effect of the secondary flow on the stream-wise velocity distribution starting only from the knowledge of the surface velocity and the entropic concept application. The analysis is conducted with the aid of data collected in a large-amplitude meandering laboratory flume for two different values of the width-to-depth ratio. Results show that the location of the maxi…

Noziedzīgo nodarījumu kopība
2016
Bakalaura darbā autors pievēršas noziedzīgu nodarījumu kopības institūtam, kas regulēts Krimināllikumā. Šim tiesību institūtam ir nozīme ne tikai pareizā noziedzīgu nodarījumu kvalifikācijā, bet arī pie soda noteikšanas. 2012.gadā tika veikti būtiski grozījumi Krimināllikumā, tostarp arī attiecībā uz noziedzīgu nodarījumu daudzējādības institūtu. Tādējādi arī tika mainīts kopības regulējums. Izvirzītie bakalaura darba uzdevumi: - apskatīt kopības institūta vēsturisko attīstību, - izpētīt kopības regulējumu Krimināllikumā un ar to saistīto problemātiku, - kā arī aplūkot ārvalstu normatīvos aktus. Atslēgvārdi: noziedzīgu nodarījumu kopība, daudzējādības veids, normu konkurence, noziedzīgu nod…
Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)
2012
Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…
Assessing HYDRUS-2D model to simulate water content and salt accumulation in a soil irrigated with a subsurface drip system: Application in a semiari…
2015
In this paper, the suitability of HYDRUS-2D model to predict the average soil water content in the root zone of potato crop irrigated with subsurface drip irrigation plant, is initially assessed on the basis of a field study. Then, the model is tested to predict the salt distribution around a buried emitter, when two different water qualities (i.e. electrical conductivity of 1.0 dS m-1 and 4.0 dS m-1), are used during the growing season (treatments T1 and T2). Finally, the soil volume in which salts accumulates, as well as the effects on crop yield is recognized for both the considered treatments.The results evidenced that predicted values of average soil water content in the root zone were…
