intro story DELWAQ


DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

 Causes of Schizophrenia

 Causes of SchizophreniaThere is no definiteness when it comes to identifying the causes of Schizophrenia. Every psychological or psychosocial factor identified earlier were considered as an etiology of Schizophrenia.Organic Factors: In this grouping, some of the factors include genetic, biochemical, metabolism, endocrine, toxic, and neurological. There were studies and findings on genetic and biochemical, but zeroing in on them is quite tricky. The anti-insulin factor is found in the blood and urine of Schizophrenic patients. In childhood schizophrenia, there will be a lag in the development of the child. One of the factors identified for it could be the oxygen deprivation during childbirth.
  • Psychosocial Factors: The Schizophrenic's profound defects in mental functioning make it impossible for them to mediate successfully between the conflicting demands of instinctual impulses, conscience, and external reality. They suffer from disappointment, frustration, and loss of self-esteem in their attempt to deal with other people and the outside world. The patient tries to deal with their unbearable (guilt or a voice of conscience accusation) internal state by mentally constructing an unreal world. In other cases, the mother-infant relationship is marked, but in which the infant encounters difficulty separating themselves from the mother and achieving individuation. In families where parents derogate and undercut each other, the child cannot use one parent as a model for identification as a love object without offending the other parent. A transmission of irrationality from parents to children causes extreme difficulty in them, establishing a satisfactory sense of their own identity. The child then gets preoccupied with "fitting together" at the expense of individuation. Devops Online Training
