The symmetry for two-dimensional (2D) dispersionless Toda lattice hierarchy (dTLH) is firstly derived, and then the 2D dTLH is extended read more based on the symmetry constraint.The commutativity of two different flows for this new hierarchy is shown, which leads to the 2D dToda lattice equation with self-consistent sources (dTLESCSs) together wit
Transnasal percutaneous endoscopic gastrostomy (T-PEG) is a novel endoscopic intervention for enteral nutrition.Peroral endoscopic gastrostomy is widely performed feeding procedure.However, it cannot be done bostik universal primer pro in 4 to 7% of cases with head & neck malignancies.T-PEG is a safe and viable alternative procedure in those patien
OBJECTIVE: To demonstrate the analytical value of a cubic parameterization the gel bottle audrey of the age curve of fertility and to explore its features, especially its usefulness in separating fertility level and fertility timing.METHODS: Using mathematical analysis, the cubic fertility curve is derived and examined in both continuous and discre
We compiled a checklist of endemic vascular plants occurring in Kazakhstan, employing an exhaustive examination of literature sources, herbarium collections, databases and field observations.Our study reveals that 451 taxa can be considered endemic to Kazakhstan, constituting 7.97% of the total vascular plant diversity in the country.These endemic
Intercultural misunderstandings involve a number of complex causes which can easily escalate into conflicts.Since conflicts are also complex, it is not easy to find solutions because there is no one solution for all problems.Systems Theory, transdisciplinarity, and the social ecological model take a holistic approach in investigating complex phenom
