Tissue culture technique plays a significant role in the growth, morphogenesis and development of tissue protocols through the supplementation of Media having all nutrients under aseptic condition. The role of tissue culture on crops is an important siblings done since a decades. Agriculture is a term which is utilized for different types of crop and livestock production, aquaculture, fisheries, and forestry for food and non-food products. Since olden days, Agriculture seems to rise since human civilization and farming has a strong relationship for food surpluses that enabled people to live in cities.Plant tissue culture (PTC) has promising role in making disease resistant variety of crops since 20th century. The technique is highly reliable in taping the economic potentials of medicinal and crop plants. In this Research, four types of seeds of Oryzae sativa, Triticum aestivum, Zea maize and Sorghum bicolor were taken and allow to germinate on filter paper moisten with nutrient solution like macronutrient, micronutrient and Vitamin solution for 2minutes. After 2 minutes, the different types of crops seeds spread over the filter paper moistened with nutrient solution in three petriplates. A filter paper was used to cover the seeds and petriplates were kept at three individual places. In this Experiment, Istpetriplate was kept under light condition, Second kept at darkroom and 3^rdpetriplate kept at open Environment. The temperature was maintained at 22 to 25⁰C. After 48 hour of observation, the seeds seem to be germinated. The seeds were kept at dark rooms seem to germinate more rapidly in comparison to seeds kept at light and Environment condition. After observation, the germinated seeds inoculated in plant growth regulators (Auxin, Gibberlin, Cytokinin and IBA) supplement Agar plus Basal Media. After one week of culture, the seedling measure 8cm and transfer to field for their proper growth. It was found that Auxin seems to plays a significant impact on growth and development of Triticum aestivum and Oryzae sativa in comparison to and Zea maize. On the other hand, though the growth and development was observed in other plant growth regulators like Gibberlin, Cytokinin and IBA but seems to be very less active on growth and morphogenesis than Auxin Agar supplemented MS Media.

The objective of this research was to summarize a depth idea about the fruitful requirements in the tissue culture of different crop varieties which have positively contribute to the biotechnological breeding programs. Thus, plant tissue culture technique empowers good candidates of plant species to be rescued and proliferated in large number to produce disease resistant varieties of different types of crops

Once hailed as one of Africa’s rare democracies now grapples with deep fractures in its democratic fabric. The recent postponement of democratic elections has sparked protests and unrest, raising critical questions about the state of democracy in the country. The violence also targeted symbols of French presence, revealing underlying tensions related to Senegal’s colonial past. The COVID-19 pandemic has strained democratic processes worldwide, raising concerns about free and fair elections.

Dielectric spectroscopy is a broadly involved procedure for exploring the electrical properties of materials. In this review, we utilized dielectric spectroscopy to look at the recurrence subordinate way of behaving of an example material. The research's objective was to learn more about the material's molecular dynamics and relaxation processes. We led estimations over an expansive recurrence range, going from low frequencies to a few gigahertz, using both impedance and capacitance estimations. A precise impedance analyzer and carefully designed sample cells made up the experimental setup. The material must have multiple dynamic modes, as our findings revealed distinct relaxation processes in various frequency regimes. By dissecting the dielectric spectra, we had the option to separate significant data about the unwinding times, actuation energies, and atomic elements of the framework. These discoveries add to a more profound comprehension of the material's electrical way of behaving and have likely ramifications in different fields, including materials science, science, and science. In general, this study demonstrates the versatility of dielectric spectroscopy as a method for defining the electrical properties and dynamics of materials.
