New global directions align agricultural land resources towards food production; therefore, marginal lands could provide opportunities for second-generation energy crops, assuming that in the difficult conditions of plant development, productivity can be maintained at relatively high levels. Sustainable bioenergy production on represents an ambitious objective, offering high-quality biofuels without competing with agri-food industry, since it allows successful feedstock to performed...

Introduction: Motion analysis, the study of movement patterns to evaluate performance, plays a crucial role in surgical training. It provides objective data that can be used assess and improve trainee's precision, efficiency, overall technique. The primary aim this is employ accelerometer-based sensors placed on wrist analyze hand motions during endoscopic sinus surgery training using sheep's head. By capturing detailed data, seeks quantify motion characteristics distinguish different levels...

Background and Objectives: This study aims to establish the sheep head as a viable anatomical model for training in functional endoscopic sinus surgery through comprehensive examination training-based assessment of participants’ satisfaction. Materials Methods: Participants were divided into three groups according their prior experience surgery; total, 24 participants included. Each participant was assigned perform designated procedures on single sheep’s head. Following completion...

The paper presents the results of experimental approach on organic waste from food industry processing for complete neutralization, energy generation and disposal. Non-oxidant processes pyrolysis based were conducted both at laboratory pilot scale aiming product neutralization with respect to pathogen germs, bio-degradation medium-long term storage risk. study represent alternatives currently used disposal solutions mainly incineration. For analysis three main types considered: primary stage...

Poultry-processing industries generate substantial quantities of waste, posing significant environmental challenges due to the complexity handling and disposal. This study explores an innovative solution that combines thermochemical treatment poultry waste with furrow-diking technology transform non-recyclable feathers bones into biochar—a nutrient-rich soil amendment. The research identifies optimal pyrolysis conditions for biochar production evaluates its effects on moisture retention,...

This paper presents the results of theoretical estimations quantity landfill gas (LFG), as well energy potential Cell A from municipal in Oradea city, Romania, based on a mathematical model.Considering three scenarios for LFG recovery according to capture system efficiency, following flows have been obtained: 157 m 3 LFG/h 45% efficiency; 209 60% and 297 85% respectively.The current efficiency real data is about 45%.On-site measurements revealed that composition 53% methane 0.72% oxygen,...

The complex parts, like block engine or inside panel door, represent a real challenge for 3D modeling with modern parametric CAD systems if we intend to reuse the future modifications. complexity of part generates large number parameters and parametrical dependencies that is difficult manage even change modifying part, often, big changes, making it easier remodeling from beginning. In this paper presented new method hierarchical allows easy modifications part. This also presents...

The paper presents the experimental results carried out on chicken farms residues for complete characterization with respect to thermal processing and energy recovery.The physical-chemical properties of poultry derived waste were experimentally determined from meat line as it is obtained.The research focused combustibility quantification appropriate chain identification.The experiments elemental composition, primary analysis specific content determination.Due unfitted classic combustion...

The present paper examines the emissions of polycyclic aromatic hydrocarbons (PAHs) resulted from thermal treatment through pyrolysis process contaminated soil with petroleum products.Specifically, across experimental work, temperature influence on PAHs and Phenanthrene remediation degree during were investigated.The pyrolytic soils was performed at different temperatures time: 400C for 60 min; 600C 30 min 800C min.The obtained results revealed that non-oxidative atmosphere between...

Romania ranks among top countries in Europe with the lowest amount of waste produced, 261 kg/capita/year, compared to northern countries, that generate almost double waste. However, it performs poorly recycling sector and management although significant amounts money have been invested over last 10 years. The paper presents 2 pilot projects regarding implementation a collection system two small communities Northern agreed adopt implement Zero Waste Strategy towards Circular Economy. After...

Within the current research, GORE™ COVER composting system was tested for treating organic waste by aerobic digestion performed in closed installation, equipped with a positive aeration and semipermeable membrane.
