In this study, we discuss an approximate set of equations describing water wave propagating in deep water. These generalized Klein–Gordon (gKG) equations possess a variational formulation, as well as a canonical Hamiltonian and multi-symplectic structures. Periodic travelling wave solutions are constructed numerically to high accuracy and compared to a seventh-order Stokes expansion of the full...

With agonist stimulation, cardiac f32-adrenergic receptors (f2ARs) are downregulated to a much greater extent than are fJ1ARs. It has been hypothesized that this effect is due to sympathetic innervation inhibiting the downregulation of ,IJARs. To test this hypothesis, the technique of coverslip autoradiography was used to localize and quantify f31AR and 2AR subtypes in tissue compartments of th...

The aim of the study was to identify trends and dynamics changes in chemical biochemical properties soil induced by rotational grazing farmed deer. Soils pH content mineral nitrogen forms, total nitrogen, organic carbon were determined activity three enzymes. monitored soils slightly acidic neutral, with 1 mol KCldm−3 ranging from 6.37 7.03. contents carbon, range 9.42–19.37 gkg−1 1.13–2.24 gkg...

The need for food is currently increasing so that to meet needs, agricultural land, both dry land and paddy fields, needed. Rice fields in Southeast Sulawesi are quite extensive, but rice productivity still low. use of inorganic fertilizers continuously a long time, results damage the physical properties soil. purpose study was determine effectiveness application complete liquid organic fertili...

Abstract. Knowledge graphs are a form of database representation and handling that show the potential to better meet challenges data interoperability, semi-automated information reasoning, retrieval. Geospatial knowledge (GKG) have at their core specialized forms applied ontology provide coherent spatial context domain including non-spatial attributes. This paper discusses research toward devel...
