In this article, we present a three-dimensional visualization technique that has been developed in order to establish an interactive immersive environment to visualize the particles in granular materials and dislocations in crystals. Simple elementary objects often exhibit complex collective behavior. Understanding of such behaviors and developments of coarse-scale theories, often requires insight into collective behavior that can only be obtained through immersive visualization. By displaying the computational results in a virtual environment with three-dimensional perception, one can immerse inside the model and analyze the intricate and very complex behavior of individual particles and dislocations. We built the stereographic images of the models using OpenGL rendering technique and then combine with the Virtual Reality technology in order to immerse in the three-dimensional model. A head mounted display has been used to allow the user to immerse inside the models and a flock of birds tracking device that allows the movements around and within the immersive environment.

The sustainability of rice production continues to be a subject of uncertainty and inquiry attributed to shifts in climatic conditions. In light of the impending climate change crisis and the high labor and water costs accompanying it, direct-seeded rice(DSR) is unquestionably one of the most practical solutions. Despite its resource and climate-friendly advantages, early maturing rice faces weed competitiveness and seedling establishment challenges. Resolving these issues is crucial for promoting its wider adoption among farmers, presenting it as a more effective sustainable rice cultivation method globally. Diverse traditional and contemporary breeding methods are employed to mitigate the limitations of the DSR approach, leveraging advanced techniques such as speed breeding and genome editing. Focusing on key traits like mesocotyl length elongation, early seedling vigor, root system architecture, and weed competitiveness holds promise for transformative improvements in DSR adaptation at a broader scale within farming communities. This review aims to summarize how these features contribute to increased crop production in DSR conditions and explore the research efforts focusing on enhancing DSR adaptation through these traits. Emphasizing the pivotal role of these game-changing traits in DSR adaptation, our analysis sheds light on their potential transformative impact and offers valuable insights for advancing DSR practices.

Strong shock wave interactions with ceramic material ceria(CeO_(2))in presence of O_(2)and N2 gases were investigated using free piston driven shock tube(FPST).FPST is used to heat the test gas to very high temperature of about 6800-7700 K(estimated)at pressure of about 6.8-7.2 MPa for short duration(2-4 ms)behind the reflected shock *** is subjected to super heating and cooling at the rate of about 106 K/*** of CeO_(2)sample was done before and after exposure to shock heated test gases(O_(2)and N2).The surface composition,crystal structure,electronic structure and surface morphology of CeO_(2)ceramic were examined using X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD),Fourier transform infrared(FTIR)spectrometry,scanning electron microscopy(SEM)and high resolution transmission electron microscopy(HRTEM).Results obtained from the experimental investigations show that CeO_(2)can withstand high pressure accompanied by thermal shock without changing its crystal *** CeO_(2)releases lattice oxygen making it possible to shift between reduced and oxidized states upon the interaction with shock heated *** to such reaction mechanism,CeO_(2)ceramic undergoes nitrogen doping with decrease in lattice *** reveal that CeO_(2)retains its crystal structure during strong shock interaction,even at elevated pressure.

The increasing demand in the diverse device applications of transparent conducting oxides （TCOs） requires synthesis of new TCOs of n- or p-type conductivity. This article is about materials engineering of ZnO-SnO2- In2O3-Ga2O3 to synthesize powders of the quaternary compound Zn2-xSn1-xlnxGaxO4-δ in the stoichiometry of x = 0.2, 0.3, and 0.4 by solid state reaction at 1275℃. Lattice parameters were determined by X-ray diffraction （XRD） technique and solubility of In3＋ and Ga3＋ in spinel Zn2SnO4 was found at 1275℃. The solubility limit of In3＋ and Ga3＋ in Zn2SnO4 is found at below x = 0.4. The optical transmittance approximated by the UV-Vis reflectance spectra showed excellent characteristics while optical band gap was consistent across 3.2 eV with slight decrease along increasing x value. Carrier mobility of the species was considerably higher than the older versions of zinc stannate spinel co-substitutions whereas the carrier concentrations were moderate.
