An increasing number of de novo missense variants have been identified in the GRIN family of genes encoding glutamate receptors, which play multiple roles in the central nervous system including mediation of a slow, calcium permeable component of synaptic transmission. This presentation will introduce the NMDA receptor family and summarize broadly what is known about the GRIN variants across multiple genes. The rationale underlying functional analysis both in vitro and in vivo will be presented, along with a snapshot of the procedures utilized by the Center for Functional Evaluation of Rare Variants. The terms “gain-of-function” and “loss-of-function” will be considered in the context of functional data, and specific data provided illustrating how these properties can vary with gene, location of the variant, and altered function among multiple properties of NMDA receptors.
Synaptic dysfunction is implicated in a variety of neurological disorders. De novo mutations in certain synaptic proteins are pathogenic. In particular, rare variants of two NMDA receptor
subunits, GluN2A and GluN2B, underlie some cases of epilepsy and neurodevelopmental disorders.
For many years, my laboratory has worked on mechanisms regulating NMDA receptor trafficking to excitatory synapses and how synaptic localization is dynamically regulated during development and in response to experience. In particular, we have studied how the long C-terminal domains of GluN2A and GluN2B regulate trafficking through protein-protein interactions and posttranslational modifications such as phosphorylation. In particular we have evaluated a missense mutation within
the C-terminal domain of GluN2B identified in a patient with ASD and described deficits in receptor surface expression and dendritic spine density. We are moving forward to make a mouse model of this mutation. More recently we are studying a missense mutation located within the C-domain of GluN2A identified in a patient with epilepsy and intellectual disability. Thus residue is a phosphorylation site and affects receptor trafficking. Our studies validate a ‘bedside to bench’
approach of studying rare variants associated with disease to better understand the function and signaling properties of NMDA receptors. We anticipate our results will allow us to better understand the structure, function and signaling regulated by the C-termini. Importantly, by characterizing these variants, we hope to gain insight into the pathogenesis of various neurodevelopmental disorders.

Climate change is being driven by global warming which is caused mainly by greenhouse gas emissions from human activities. Buildings contribute significantly to greenhouse gas emissions through their operations and electricity usage for HVAC equipment. As developing countries like India experience rapid growth and construction of new buildings, the emissions from building HVAC systems are projected to rise substantially and comprise a larger share of countries' total emissions over time if no action is taken. More sustainable 'green' building practices that improve energy efficiency can help reduce the environmental impacts of buildings and their HVAC systems.

Production of electricity from agricultural soil and dye industrial effluent ...eSAT Journals
Abstract Microbial Fuel Cells (MFCs) or biological fuel cells are biochemical system that drives energy by mimicking bacterial interactions found in nature. It converts chemical energy into electrical energy without any combustion reactions being carried out. In our research, soil MFC was constructed and bioelectricity was harvested from two different types of soil samples such as agricultural soil and dye industrial effluent soil. The production of electricity was measured by using power measurements and it was compared for both the soil samples. The dye industrial effluent soil produced 0.93V of electricity continuously for 650 hours whereas the agricultural soil produces 0.82V for 400 hours. Key words: Microbial Fuel Cells (MFC’s), agriculture soil, dye industrial effluent soil, power measurement, electricity.

Wet oxidation is a hydrothermal treatment of aqueous solutions of biologically
recalcitrant and hazardous chemicals/wastes. It is the oxidation of dissolved or suspended
matter in water using an oxidant such as ozone, oxygen, hydrogen peroxide, air etc. It is
referred to as Wet Air Oxidation (WAO) when air is used as an oxidant. The oxidation
reactions generally occur at temperatures above the normal boiling point of water (100
°C) but below its critical point (374 °C). The system must also be maintained under
pressure i) to maintain the solution in liquid form; ii) to avoid excessive evaporation of
water and also iii) to conserve energy, as the evaporation needs latent heat of
vaporization. Under wet conditions, many compounds get oxidized which would
otherwise not oxidize under dry (not wet) conditions, even at the same temperature and

A solid waste or combination of solid wastes that,
because of quantity, concentration or physical,
chemical or infectious characteristics, may cause or
significantly contribute to an increase in mortality or
an increase in serious, irreversible, or incapacitating
reversible illness or pose a substantial hazard to
human health or the environment when improperly
treated, stored, transported, disposed, or otherwise
managed. About 290 million tons of hazardous
wastes are generated in the U.S. each year. About
4% is recycled. The rest is treated, stored or
disposed.

design of common hazardous waste treatment, storage and ....arvind kumar
This document outlines regulations and guidelines for the design, operation, and closure of common hazardous waste treatment, storage, and disposal facilities in India. Key points include:
- The operator or occupier is responsible for establishing these facilities and identifying appropriate sites. An environmental impact assessment must be conducted and approved by regulatory authorities.
- Facilities must be designed according to technical criteria like ensuring proper distance from habitats, infrastructure, and water sources. Liners, leachate collection, gas control, and final cover systems are required.
- Operation and closure of landfill sites must follow approved designs and ensure environmental protection. Regular monitoring of facilities is mandated after closure for a specified period.
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.
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.
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.

Energy Situation
The availability of power has increased but demand has consistently outstripped
supply and substantial peak & energy shortages of 7.1% & 11.2% prevail in India.
These problems emanate from:
• Inadequate power generation capacity.
• Lack of optimum utilisation of the existing generation
capacity
• Inadequate inter-regional transmission links
• Inadequate and ageing sub-transmission & distribution
network leading to power cuts and local failures/faults
• T&D losses, large scale theft and skewed tariff
• structure
• Slow pace of rural electrification
• Inefficient use of electricity by the end consumer
• Lack of grid discipline

15. Environment Management Plan
Air Quality Monitoring and Management
• Periodic Monitoring of air quality
• Maintenance of grass cover
• Black top roads
• Odor control by rapid stabilization
• Minimizing working distances internally
• Green belt development to attenuate noise
• Silencers to generators and vehicles
Water Quality – Surface and Ground
• Clean water diversion
• Proper leachate management
• Periodic Monitoring
• Double composite liner system
• Effective drainage system
• Appropriate capping
• Spill control procedures
Activity wise Mitigation Measures During
• Site Clearance
• Construction
• Operation
• Closure
• Post-closure Phase
EMP should also delineate the environmental monitoring plan for compliance of
various environmental regulations
