need of nuclear energy for growing IndiaShubham Babar
Nuclear energy provides 20% of the world's electricity through 440 reactors in 31 countries. India plans to significantly expand its nuclear power industry and generate an additional 25,000 MW of nuclear power by 2020. India is developing thorium-based fast breeder reactors and participating in the ITER nuclear fusion project. Nuclear power could provide a non-polluting alternative to meet India's growing energy demands, which are expected to double electricity consumption to 5000-6000 kWh per capita by 2050. While prospects for nuclear energy in India are bright in the long run, the benefits of the US-India nuclear deal and India's established nuclear industry suggest nuclear power has potential to be a major electricity source in the future.
The document discusses future energy sources and sustainability. It notes that current fossil fuel usage will lead to an energy crisis this century. Alternative energy companies are developing renewable sources like solar and geothermal to prepare. Graphs show fossil fuel consumption increasing while awareness of sustainability grows. The conclusion advocates for renewable investments, and warns demand from countries like China will double by 2030 if changes are not made.
Marine energy provides alternatives to address issues with fossil fuels like pollution and climate change as global energy consumption increases. Current methods extract energy from tides using tidal power plants and tidal turbine systems. Other forms of marine energy include ocean thermal energy conversion which uses temperature differences in ocean waters to generate electricity, and wave energy which some countries like Portugal and Scotland have started capturing from ocean waves.

Title: A sustainable (energy) future
After a brief preface on intellectual self-defense, the presentation discussed the science underpinning our understanding of climate change, followed by an analysis of worldwide energy use.
The experience curve was introduced as a force arguably more powerful than Moore's Law (because it applies in virtually every manufacturing sector) and the main reason that renewables (wind and solar, for the time being) are likely to displace fossil fuel and nuclear power in the coming decades -- not for reasons of conscience, but reasons of cost.
Lastly, the metaphor of the "utility death spiral" was introduced to explain the probable impact of efficiency and renewables, on the fossil-and-nuclear dominated utility sector, in coming decades.
This document discusses the advantages and disadvantages of nuclear fuel (uranium) energy. It notes that uranium energy is environmentally friendly as it does not emit greenhouse gases, is powerful and efficient compared to other energy sources, and can produce energy reliably. However, it also has disadvantages, such as accidents like Fukushima, the difficulty of managing radioactive waste, limited global quantities, restrictions on import/export, and safety issues.
The document proposes reducing dependence on fossil fuels by increasing use of nuclear power, renewable energy, and more efficient transportation and buildings. It suggests using nuclear power for electricity generation, ships, and potentially trains. Renewable energy like solar, wind, and biomass can offset fossil fuel usage for power and transportation. More efficient cars, use of biofuels and electric vehicles also reduce fossil fuel demand. Improving building energy generation and usage through solar, wind, and better insulation contributes. However, plastics remain challenging as they heavily rely on natural gas. Overall, a variety of solutions can significantly lower but may not fully eliminate fossil fuel dependence.

Presentation by Surovi of energy sources.pptxSayedSakib3
Energy plays a key role in economic growth and is indispensable for agriculture, transport, business, and domestic needs. There are three main types of energy: non-renewable, renewable, and nuclear. Non-renewable sources include fossil fuels like coal, crude oil, and natural gas. Renewable sources include hydropower, solar, wind, geothermal, and biomass. Nuclear energy is produced through nuclear fission and fusion inside atoms. Alternative energy sources are being developed and used to address concerns with fossil fuels.
Pakistan faces an ongoing energy crisis due to a shortage in power supply compared to demand. This is caused by issues like poor management, corruption, theft, wastage, and lack of investment in alternative energy sources in the past. Developing renewable resources like solar, wind, and hydroelectric power could help address Pakistan's energy crisis.
Fusion has the potential to be a sustainable energy source that avoids the issues of fossil fuels and current nuclear power. It involves fusing two light atomic nuclei to produce energy. The fuel for fusion, mainly deuterium, is widely available. Fusion also avoids producing long-term radioactive waste or carbon emissions. Significant challenges remain, such as achieving the extremely high temperatures required for fusion. International experiments like ITER in France aim to demonstrate the scientific and technical feasibility of fusion power.
This document provides an overview of renewable energy sources and technologies. It discusses the potentials and limitations of various renewable resources like solar, wind, hydropower, and biomass.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
