3D Modeling of Patrimonium Objectives Using Laser Technology

This paper aims to present the advantages of using the terrestrial laser scanning technology (TLS) as a method of creating a 3D database and 3D documentation. This state-of-the-art technology is an innovation that has the advantage of acquiring a large amount of data in a short time. This technology together with UAV equipment has the advantage of obtaining a digital terrain model. The creation of 3D patrimony models, archaeological objects and sites in their current state requires specialized equipment, knowledge, and have a powerful methodology capable of digitally capturing and shaping geometric details and fine layout of these sites. Digital recording, documentation and preservation are required because our patrimony (natural, cultural or mixed) suffers from various anthropogenic and/or natural actions (natural disasters, climate change and forgetfulness of human neglect)

Associations between environmental non-essential heavy metals, ecobiochemistry and health

Environmental heavy metals should be a concern of the entire world due to its impact on the animal and human population. "Heavy metals" is a generic name used for metals characterized by relatively high atomic weight, density, and atomic number. Some of the heavy metals are essential nutrients for animals and humans, but when their ingested concentration exceeds the needs, their homeostasis is unbalanced and health status is impaired. Non-essential heavy metals are minerals that are harmful to the environment and living organisms. The environment is the main source of minerals provided by soil, water and air. Any deficiency or excess of minerals in the environment will be transferred to the living organisms. Plants, meat and water – are ingredients of humans' diet, and because of that, any overload affects the minerals' homeostasis that could lead to accumulation in target organs – mainly in the liver and kidney, also in the brain, heart, lungs, and other organs. Ecobiochemistry and xenobiochemistry are two complex sciences that are trying to find correlations between the biochemical processes related to the minerals’ needs, intake, and excretion to assure a good health status

Chitosan edible coating: a potential control of toxic biogenic amines and enhancing the quality and shelf life of chilled tuna filets

Edible films and coatings offer great potential to support sustainable food production by lowering packaging waste, extending product shelf life, and actively preserving food quality. Using edible coatings containing plant extracts with antioxidant and antibacterial characteristics could help to enhance the quality and shelf life of fish products. In this study, the combination effect of chitosan with beetroot, curcumin, and garlic extracts on biogenic amines (BAs) reduction, biochemical quality [pH, thiobarbituric acid index (TBA), trimethylamine (TMA), and total volatile base (TVB)], shelf life and sensory characteristics of tuna filets was investigated over 14 days of refrigerated storage compared to control (uncoated) samples. The results showed that the coated samples experienced a lower increase in BAs levels than the control samples. Among the treated samples, chitosan incorporated with curcumin (CH-C) showed the highest reduction in BAs formation (1.45 – 19.33, 0.81 – 4.45, and 1.04 – 8.14 mg/kg), followed by chitosan with garlic (CH-G) (1.54 – 21.74, 0.83 – 5.77, and 1.08 – 8.84 mg/kg), chitosan with beetroot extract (CH-B) (1.56 – 31.70, 0.84 – 6.79, and 1.07 – 10.82 mg/kg), and chitosan without extract addition (CH) (1.62 – 33.83, 0.71 – 7.82 and 1.12 – 12.66 mg/kg) compared to control samples (1.62 – 59.45, 0.80 – 11.96, and 1.14 – 20.34 mg/kg) for histamine, cadaverine, and putrescine, respectively. In addition, the rate of increase in pH, TBA, TMA, and TVB of all coated treatments was lower than in the control samples. Sensory evaluation results revealed that chitosan-treated samples incorporated with beetroot, garlic, and curcumin extracts showed good quality and acceptability characteristics. Overall, chitosan edible coatings incorporated with beetroot, garlic, and curcumin extracts reduced the formation of biogenic amine, delayed biochemical deterioration, and extended the shelf life of tuna filets. Among the treated samples, CH-C demonstrated a remarkable superiority in all the studied parameters. Therefore, this study provides a promising strategy for the incorporation of active compounds in edible coatings to improve the quality and safety of foods during storage
