Abstract — Mining waste reduction methods include all
mining processes beginning from resource distribution until
final yield in the plant. For comparing and testing possibilities of
mine waste reduction cooperation project has been set up aiming
to create a transnational network with regional networks. The
activities carried out on the regional and transnational level will
secure better access to knowledge, state-of-the-art technologies
and good practice to Small and Medium Enterprises active in
the mineral waste management & prevention sector. The project
addresses all the waste management challenges and
opportunities, which face the Baltic Sea Region mining industry,
which should be understood as extending to all forms of
extraction of natural non-renewable resources. The project
activities will be facilitated by the commitment to participate by
an additional 15 associated organizations representing mining
industry stakeholder associations and/or national government
bodies.
Behaviour of Lustrous Carbon Additives in Green Sand Castingijtsrd
The advent of High Volume, High Density and High Pressure Moulding Lines has changed the logistics of Molding Techniques and selection of additives significantly. Having 4 main ingredients, Base Sand, Bentonite, Lustrous Carbon Additives and Water, the properties of the Sand Mold resulting from this simple mixture to deliver target casting quality is complexly variable. Sand Control is an Art' as any foundry man will willingly emphasize. It is well accepted that no two foundry sand systems are the same. Even a single foundry Unit or foundry group having two or more molding lines, along with separate Sand preparation lines, whether in the same campus or in different locations, sand preparation and sand parameters will normally differ in each sand loop The role of quality in additives has therefore become even more important than when one could feel' the sand and make changes accordingly. Now, additives and ingredients have to be engineered precisely for the application with assured reproducibility in chemistry, grain fineness and other parameters.

Use of Cow Dung Ash in Eco Friendly Concreteijtsrd
It has been estimated by World Health Organization WHO that about 5 of total CO2 released into the atmosphere is from cement industry. Besides being an natural toxin, the measure of warmth energy needed for creation of concrete is around 1500 °C which requires more energy. Cement concrete produced with ordinary cement are to be replaced by eco friendly concrete. Locally available waste material like rice husk ash, cow dung ash, animal waste ash etc can be a better option for the replacement of cement in concrete up to an extent. This paper presents the possibility of utilizing Cow dung ash CDA as a supplementary cementing material in cement concrete. Trial examinations completed to concentrate on the cow waste debris on the strength of cement. Concrete was to some extent supplanted with four rates 5 , 10 , 15 , and 20 of cow manure debris by weight. The compressive strength and flexural strengths of the concrete specimens were determined at 7, 14 and 28 days respectively. From the outcomes significant ends can be attracted terms of different boundaries like workability, flexural strength and compressive strength. Kapil Batham | Prof. M. C.

A review on utilization of mine waste on black cotton soileSAT Journals
Abstract Mine wastes are one of the chronic waste concerns. The volume of solid waste generated during mining process, is one of the main pollution concern. The presence of high concentration of heavy metals and acid producing mineral phases can endanger the environment if management of these wastes are not addressed properly. Mine wastes have numerous ecological effects viz Air, Land and Water. There is a great difficulty in finding space for the storage of wastes generated in enormous quantity. The review of past studies indicated that 50 to 60% of mine waste by volume can be used as coarse grained particle and 10 to 15% by volume as fine aggregate. Despite quite a lot of attempts to diminish the amount of waste, mine waste remains one of world’s largest waste streams. Black cotton soil on the other hand is problematic due to the presence of momtmorillonite that imparts high swell- shrink potentials. These soils are very hard when dry but loose strength completely when wet. Pavement surface on poor soil subgrade show early distress causing pavement failure. The present study examines the utilization of these wastes as stabilizers for black cotton soil for unpaved road construction. Keywords: Mine Waste, slag aggregate, Solid Waste Materials, Iron Ore slag
Effect of mill scale and fly ash waste on the performance of cement mortareSAT Journals
Abstract
This paper investigates effect of mill scale and fly ash wastes as a replacement of fine aggregate generally natural sand on the performance of cement mortar. Utilization of fly ash and mill scale in cement mortar production not only provides significant environmental benefits but also enhances performance of the cement mortar when used at optimum amounts. They may be used in the form of finely ground additive to replace part of aggregates in cement mortar. This study looked at the feasibility of mill scale and fly ash waste inclusion as partial aggregate replacement in normal cement mortar. Properties of cement mortar incorporating fly ash and mill scale waste as partial substitution for natural aggregate were investigated. The study involves six replacement levels of mill scale and fly ash wastes into cement mortar for each mix design. Mortar cubes are tested for strength, & water absorption. The partial replacement of fine aggregate by M(3,30), M(5,30), M(8,30), M(10,30), M(12,30), M(15,30) ( M-mix of mill scale & fly ash %) improves the properties of normal mortar. In the design mix of industrial wastes produced, percentage of fly ash is kept constant (30 %) and mill scale is varied from 0 to 15 % by weight of natural sand. The test results indicate that the mechanical properties of mill scale and fly ash modified mortar are improved to a great extent, whereas the water absorption is reduced as compared to that of plain mortar.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
