Kvalitet obrazovanja kao preduslov za informacijsko i medijsko opismenjavanje zumera u Crnoj Gori

Vjesnik Bibliotekara Hrvatske, 2022
Cilj. U ovom radu analiziraćemo staro-nove probleme u obrazovnom sistemu koji onemogućavaju medijsko opismenjavanje zumera. Ova tema je aktuelna od 2008. godine, ali i pored brojnih kampanja rezultati nisu vidljivi.

Recent Development on Underground Coal Gasification and Subsequent CO2 Storage [PDF]

, 2015
Underground coal gasification (UCG) is the in-situ conversion of deep underground coal to synthesis gas for heating, chemical manufacturing and power generation. UCG has been the subject of extensive pilot testing but technical and environmental concerns

Perturbation evolution in cosmologies with a decaying cosmological constant [PDF]

, 1997
Structure formation models with a cosmological constant are successful in explaining large-scale structure data, but are threatened by the magnitude-redshift relation for Type Ia supernovae.

Efficient Quantum Circuits for Schur and Clebsch-Gordan Transforms [PDF]

, 2004
The Schur basis on n d-dimensional quantum systems is a generalization of the total angular momentum basis that is useful for exploiting symmetry under permutations or collective unitary rotations. We present efficient (size poly(n,d,log(1/\epsilon)) for

Marginal AMP Chain Graphs [PDF]

, 2014
We present a new family of models that is based on graphs that may have undirected, directed and bidirected edges. We name these new models marginal AMP (MAMP) chain graphs because each of them is Markov equivalent to some AMP chain graph under ...

Prediction method of surface subsidence due to underground coal gasification under thermal coupling

Meitan kexue jishu, 2023
Underground coal gasification (UCG) is an essential part of the low-carbon green coal mining technology system. The implementation of the “double carbon” goal of the coal industry has brought excellent development opportunities for UCG. However, UCG will

Back-reaction of Cosmological Fluctuations during Power-Law Inflation [PDF]

, 2006
We study the renormalized energy-momentum tensor of cosmological scalar fluctuations during the slow-rollover regime for power-law inflation and find that it is characterized by a negative energy density at the leading order, with the same time behaviour

A Discussion on CO2 Sequestration in the UCG Space Based upon the Review of the UCG Residue Physicochemical Properties

Minerals, 2023
The strategic goal of “carbon peaking and carbon neutrality” has promoted further reform of the global energy system. Additionally, coal is still the dominate form of energy consumption. Underground coal gasification, which changes the method of coal utilization, is an important way to execute clean coal development and clean utilization, and is also ...
