What is Dom in biology?

What is Dom in biology?

Definition. Dissolved organic matter is a heterogeneous class of water-soluble compounds that contain reduced (organic) carbon from a variety of biological and geological sources with a wide range of chemical reactivity. Dissolved organic matter is a key component in the biogeochemical cycling of carbon.

What is Dom in marine biology?

The enormous size and reactivity of the pool of dissolved organic matter (DOM) in the oceans makes it a critical component of the global C cycle. The primary source of DOM, encompassing both dissolved organic carbon (DOC) and nitrogen (DON), in marine environments is phytoplankton production.

What is Dom in plants?

Dissolved Organic Matter (DOM) plays an important role in the growth of plants. DOM provides numerous benefits to plant growth due to its molecular structure. It helps to break up clay and compacted soils, assists in transferring nutrients from the soil to the plant and enhances water retention.

What is Dom in water?

Dissolved organic matter (DOM) is found in every water body, both marine and freshwater. It is a heterogeneous mixture derived primarily from the decomposition products of plant material, bacteria and algae.

What does DOM stand for?

The Document Object Model (DOM) is an application programming interface (API) for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated.

What is refractory organic carbon?

About 20% of the organic carbon produced in the sunlit surface ocean is transported into the ocean’s interior as dissolved, suspended and sinking particles to be mineralized and sequestered as dissolved inorganic carbon (DIC), sedimentary particulate organic carbon (POC) or “refractory” dissolved organic carbon (rDOC).

What is particulate organic carbon in ocean?

Introduction. Particulate organic carbon (POC) is operationally defined as all combustible, non-carbonate carbon that can be collected on a filter. The oceanographic community has historically used a variety of filters and pore sizes, most commonly 0.7, 0.8, or 1.0 μm glass or quartz fiber filters.

What is refractory dissolved organic carbon?

What is DOM in hospital?

Kolkata: Engineers, graduates and postgraduates were among 8,000 people who have applied for six posts of laboratory assistants, also called ”dom” in the morgue parlance, to handle corpses at a state-run hospital in Kolkata, an official at the medical establishment said on Saturday.

What is DOM with example?

The Document Object Model (DOM) is an application programming interface (API) for valid HTML and well-formed XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated.

What is a refractory organic?

A variety of organic compounds are classified as refractory when they’re poorly biodegraded and/or exhibit a low value for the ratio of biological oxygen demand to chemical oxygen demand (BOD:COD).

What is a refractory molecule?

Definition. Molecules with a very high sublimation temperature are termed refractory. Such molecules condense at high temperature in the solar nebula or in stellar envelopes; they include silicon carbide and the iron and magnesium silicates that are thought to form the cores of many interstellar dust particles.

What is Dom and pom?

Dynamic exchanges between dissolved organic matter (DOM) and particulate organic matter (POM) plays a critical role in organic carbon cycling in coastal and inland aquatic ecosystems, interactions with aquatic organisms, mobility and bioavailability of pollutants, among many other ecological and geochemical phenomena.

What is particulate carbon?

Particulate carbon consists of both elemental carbon, from the incomplete combustion of fossil fuels and the pyrolysis of biological material during combustion, and organic carbon which may be either primary or secondary.

What is refractory organics?

What Dom stand for?

Document Object Model
Introduction. The Document Object Model (DOM) is an application programming interface (API) for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated.

What is Dom short for?

Dom is a masculine given name, frequently a short form (hypocorism) of Dominic or Domenic.

What is the main function of DOM?

The Document Object Model (DOM) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects; that way, programming languages can interact with the page.

What is a DOM structure?

The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree.

What is the difference between labile and refractory Dom?

Labile DOM comprises organic compounds with lifetimes from minutes to days that mostly escape analysis, while semi-labile and semi-refractory DOM are turned over within 1 to 20 years and accumulate only above a seasonal or permanent pycnocline, respectively.
