Cogeneration involves the sequential conversion of fuel into multiple usable energy forms. It can produce both electrical and thermal energy, unlike conventional systems. There are two types of cogeneration systems - inplant power generation and reject heat utilization. Inplant power generation produces steam at a higher temperature than needed for manufacturing to also generate electricity using a turbine generator. Reject heat utilization uses excess steam from a power plant for manufacturing. Topping cycles produce electricity first while bottoming cycles produce heat first. Cogeneration provides benefits like fuel economy, lower capital costs, and protection from power outages. Common technologies are steam turbine, gas turbine, combined cycle, and diesel engine systems.
A thermal power station converts heat energy into electrical power by boiling water to produce steam that spins turbines connected to electrical generators. Water is heated in a boiler, turning it into high-pressure steam that drives the turbine, which turns a generator to produce electricity. After passing through the turbine, the steam is condensed back into water and recycled to be heated again in a closed loop system. Thermal power stations use various heat sources like coal, natural gas, nuclear reactions or solar thermal to produce the steam.
The document discusses wind energy and the components of a wind turbine. It begins by explaining that moving air has kinetic energy which is transferred to the wind turbine blades, causing them to spin. The main components of a wind turbine are the foundation, tower, blades, hub, nacelle, generator, brake, gearbox, yaw system, and controller. The generator converts the mechanical energy of the spinning blades into electrical energy. Larger wind turbines have gearboxes to increase the blade speed to a suitable rate to power the generator.
Thermal power plants generate electricity by burning coal to produce steam that drives turbines connected to generators. They are a major source of electricity in many countries. In India, thermal power plants make up 75% of electricity generation. Coal is pulverized and burned in a boiler to heat water into steam. The high-pressure steam spins turbines that power generators to produce electricity. The steam is then condensed in a condenser using cooling water from cooling towers before being returned to the boiler as feedwater to repeat the process. While thermal plants provide reliable base-load power, they also produce significant air pollution and carbon emissions.
Tidal energy can be harnessed by constructing dams or barrages between tidal basins and the sea. During high tide, seawater fills the basin through sluice gates and turbines. During low tide, the water flows back to the sea through the turbines, turning them to generate electricity. There are different types of tidal power plants based on the number of basins and generation cycles. Single basin one-way plants generate power during ebb tides only, while double basin plants alternate generation between two basins to provide continuous power. Tidal energy is a renewable source but has high capital costs and generation varies with tidal patterns.

Because the turbine generates rotary motion, it is particularly suited to be used to drive an electrical generator – about 80% of all electricity generation in the world is by use of steam turbines.
Rotor is the heart of the steam turbine and it affects the efficiency of the steam turbine. In this project we have mainly discussed about the working process of a steam turbine. The thermal efficiency of a steam turbine is much higher than that of a steam engine.
A power plant in which nuclear energy is converted into heat for use in producing steam for turbines, which in turn drive generators that produce electric power. Also known as atomic or nuclear power plant.

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.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
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.

3. ABSTRACT
Thermal Power plants are the major source of generation of electricity for any developing country.
Around 60% of electricity generation in our country is met by thermal power plants. Fuel is blown
into the combustible chamber of the boiler where it is burnt at high temperature where Heat energy
converts water into steam. High energy steam is passed through the turbine and the steam creates
force on the turbine causing the shaft to rotate at high speed. A generator is coupled at one end of
the turbine shaft which generates power. The thermal power plant has serious impacts on land ,
soil, air and various social impacts the thermal power plant are also said to emit large amount of
mercury and generate large quantity of fly ash which destroys the surrounding environment. These
plants also consume a large amount of water. Due to these problems they require a proper
Environmental impact assessment before commencement of the project which is not done
judiciously in our country. Various mitigation measures for the control of pollution caused by
thermal power plants along with some new technologies are discussed.
4. INTRODUCTION
A thermal power station is a power plant in which the prime mover is steam driven.
Water is heated, turns into steam and spins a steam turbine which drives an electrical
generator. After it passes through the turbine, the steam is condensedin a condenser
and recycled to where it was heated; this is known as a Rankine cycle. The greatest
variation in the design of thermal power stations is due to the different fossil fuel
resources generally used to heat the water. Some prefer to use the term energycenter
because such facilities convert forms of heat energy into electrical energy. Certain
thermal power plants also are designed to produceheat energy for industrial purposes
of district heating, or desalination of water, in addition to generating electrical power.
Globally, fossil fueled thermal power plantsproducea large part of man-made CO2
emissions to the atmosphere, and efforts to reduce these are varied and widespread.
The energy efficiency of a conventional thermal power station, considered salable
energy produced as a percent of the heating value of the fuel consumed, is typically
33% to 48%.
