In the coffee industry, several by-products are generated during production and consumption of represent an important waste from environmental viewpoint. For improving knowledge about this issue, a laboratory vermicomposting study silverskin (CS) spent grounds (SCG) spiked with mature horse manure (HM) in different proportions using earthworm Eisenia andrei was carried out. The 60-day focused on biological parameters such as total biomass gain, growth rate, cocoon production, mortality. This...

ABSTRACTThis paper analyzes the ability of magnesium oxide-based additives to stabilise a low bearing gypsum marly soil, in order reach subgrade requirements. This soil was not adequate for stabilisation with lime or cement because its high sulphate content. Binders considered this investigation were composed three reactive Mg products and by products, both without ground granulated blast furnace slags (GGBS). They compared two cements an aerial as stabilisers laboratory field trial....

Nowadays, huge amounts of refractory materials are generated around the world. The majority them lack valorization methods. This study analyzes ability a doloma and two magnesia spent wastes as soil stabilizers on their own, well when combined with Ground-Granulated Blast Furnace Slags (GGBS). These showed limited for soil’s plasticity modification from index 15.6 to minimum 12.7. high pH additives increased 7.88 values in range 10.94–11.25 before 28 days, allowing development pozzolanic...

In this investigation, the Taguchi method was employed to optimize a mix based on four natural by-products for rammed earth construction. Two separate studies were conducted enhance dry density and Unconfined Compressive Strength (UCS). The materials assessed across different levels, with moisture content also factored in as parameter within statistical analysis of 16 combinations. predicted combinations which Particle Size Distribution optimized UCS well their values. From results, Moisture...

This article is based on digital terrain models (DTMs) and their applications in civil engineering carried out at the Public University of Navarre. One drawbacks use these synthetic surfaces need to characterize quality, a very important issue for its economic importance but difficult determine nonempirical manner. We will review techniques most commonly used estimate quality propose new method control DTM which high accuracy required. Among advantages this that no reference model needed,...

In the present work, lavender waste, a residue of essential oil extract industry, was used to feed Eisenia andrei with mature horse manure at ratios 0:100, 25:75, 50:50, 75:25 and 100:0 on dry weight basis. Vermicomposting carried out for 70 days in laboratory conditions. Biological parameters such as population build-up, total biomass, mortality cocoon production were observed measured. Increasing concentrations waste affected positively growth reproduction worms significant way. The 100%...

Abstract From the field of “Geomatics Engineering”[1], better known as “Topographic Engineering” and other fields “surveyors”, has always driven knowledge our environment in order to capture it on a support then allow users work, taking decisions where you’ve never been, are early nautical charts, world map, cartographic maps cities countries, orthophotos more recently around digital medium, satellite images, google earth, etc... Augmented reality allows us make visible developing products...

In the field of engineering, best results can be obtained if we are able to interact with our models. Customers generally want models or designs for new products, so developing various alternatives visualization, such as Virtual and Augmented Realities based on accurate no need using specific software. order have a better global knowledge possibilities, in this paper show situation capabilities these technologies. From developed commercial programs tools industrial design, propose workflow...

In this investigation, four distinct by-products of natural materials were used to compose a mix for rammed earth construction. The these materials, which have various granulometry, affords many potential combinations, making the analysis different combinations highly complex. Taguchi method, statistical approach renowned significantly reducing number ex-periments in complex systems, was employed address challenge. Each ma-terials assessed across levels, with moisture content also factored...

This paper investigates the ability of insulation cellulose fiber powder (CFP) to be pelletized for its valorization as biomass fuel. CFP is a waste originating from manufacturing that lacks any method because boron salts content. A sugar byproduct and lignosulfonate (LS) were considered binders pellet process. Physical tests carried out characterize pellets’ performance. Chemical combustion state potential green energy source. Raw showed good in pelletization durability range 15–30%...

The Helmholtz Zentrum Berlin is carrying out two accelerator projects which make use of high gradient Continuous Wave (CW) Superconducting Radiofrequency (SRF) cavities: bERLinPro and BESSY-VSR. In both projects, a prompt detection quench crucial to avoid damages in the cryomodules cavities themselves. this paper, response real time estimation cavity parameters using transmitted forward RF signals simulated, order perform detection. estimated half bandwidth compared with dissipated energy...

Abstract The study was conducted to assess the feasibility of using Eisenia andrei earthworms for vermicomposting hop remains from a lupulin extraction enterprises brewing industry. Vermicomposting process within 70 days ( Humulus lupulus ) wastes blended with horse manure at five different ratios triplicate in laboratory conditions. Number worms, cocoons, and hatchlings were observed recorded weekly as earthworm biomass, population build-up reproduction biological parameters. results showed...

Polyester polymer concretes can substitute conventional based on their usually good mechanical strength, adequate physical properties, and high resistance against aggressive chemical environments. They also show a potential for using recycled targets in manufacturing. This paper analyzes the fresh cured properties of polyester containing two metallurgical wastes, namely: ladle slag alumina filler. Both require higher resin dosage than sand. The standard consistency test showed low...

In a world where information is so important, the ensemble formed by An Unnamed Aerial Vehicle (UAV) and sensor opens door to techniques unthinkable just decade ago. this paper several novel applications combination of sensors UAV have proven their effectiveness: monitoring application using technique was used control transfer large metal dome in sports hall city Vitoria-Gasteiz (Spain), an operation great technical difficulty, semi-automatic creation orthoimage expanse field, determining...

Abstract. Among the many valuable uses of artificial intelligence in field museums, it may assist classification out-of-context items. This paper deals with problem identification dinosaur teeth (a type fossil that is usually found scattered), which can be tackled by means multivariate algorithms (such as principal components, discriminant or cluster analyses) taking a starting point series morphometric values (i.e., distances between specific points tooth). A good interpretation requires...
