1. THE INFLUENCE OF THE FILM FORMED ON THE PRATO CHEESE SURFACE DURING THE NACL AND KCL SALTING PROCESS: APPLICATION OF THE FINITE ELEMENT METHOD AND NEURAL NETWORKS OF THE SELF-ORGANIZING MAP (SOM) AND MULTILAYER PERCEPTRON (MLP) TYPES
Sodium chloride is used in the cheese salting process as it promotes sensory changes and food preservation. However, in excess can cause hypertension problems, and for this reason, it has been partially replaced by potassium chloride. In the present work, Prato cheese was subjected to joint diffusion of NaCl and KCl by immersion in static and stirred brine.

2. Green biosynthesized Satureja rechingeri Jamzad-Ag/poly vinyl alcohol film: quality improvement of Oncorhynchus mykiss fillet during refrigerated storage
Abstract The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate the freshness of Oncorhynchus mykiss fillets during 14 days at the refrigerated temperature. The 160 pieces of fish were enfolded in 4 types of films as main group-series. The main com

3. Compatibility and characterization of Bio-PE/PCL blends
Abstract In this work, blends based on environmentally friend polymers such as Biopolyethylene (Bio-PE), Polycaprolactone (PCL) and Polyethylene graft maleic anhydride (PEgMA) added as compatibilizer agent were produced by conventional extrusion, aiming to produce bio-blends with synergic properties at low processing cost, being at same time non-polluting an

4. Stability of Nanocomposite Edible Films Based on Polysaccharides and Vitamin C from Agroindustrial Residue
The agroindustrial residue from the production of acerola pulp is rich in residual vitamin C. Thus, aiming its extraction and stabilization, this work proposed the nanoparticle (NP) encapsulation via ionic gelation with subsequent preparation of nanocomposites (NC) film based on galactomannan matrix. NP were characterized and their stabilities were evaluated

5. Properties of barrier shrink bags made with EVOH and polyamide for fresh beef meat preservation
Abstract The objective of this work was to compare the barrier and mechanical properties and shrinkability of coextruded films chlorine-free, with high barrier chlorine multilayer films traditionally used to preserve fresh beef. Four 9-layer barrier-shrink films containing PET, ethylene ionomers, polyamide PA66/6 modified with amorphous PA, 32 or 44 mol% EV

6. Supramolecular Approach to Decorate Multi-Walled Carbon Nanotubes with Negatively Charged Iron(II) Complexes
Poly(4-vinylpyridine) (P4VP) and P4VP/pentacyanoferrate(II) metallopolymer were used to suspend up to 1 mg mL-1 of multi-walled carbon nanotubes (MWCNT) in ethanol/water mixtures, providing noncolavent decoration of MWCNT with electroactive iron complex. The major interaction between polymer side chains and nanotubes is via π-π stacking, rather than charge

7. Resisting Invasions: Indigenous Peoples and Land Rights Battles in Mabo and Terra Vermelha
Abstract: This article examines two feature films, focusing on the link between Indigenous cinema, environmental preservation and land rights. The first film is Mabo (2012) directed by Aboriginal filmmaker Rachel Perkins. It centres on a man's legal battle for recognition of Indigenous land ownership in Australia. The second film is Terra Vermelha (Birdwatch

8. Corrosion resistance of 2024 aluminum alloy coated with plasma deposited a-C:H:Si:O films
AA 2024 aluminum alloy is widely employed in aeronautic and automobilist industries. Its hardness and low density are attractive properties for such industrial areas. However, since it contains copper, it undergoes severe corrosion in aggressive media as saline or low Earth orbit environments. In this work, it was investigated the properties of films deposit

9. Modified atmosphere efficiency in the quality maintenance of Eva apples
Modified atmosphere is a method of food preservation that provides increased lifetime, decreases deterioration losses, and facilitates marketing. The objective of this study was to evaluate the efficiency of different plastic films in modifying the atmosphere around Eva apples to assure quality maintenance during postharvest storage. The fruits were cleaned

10. Conservação de toletes de palmito Pupunha (Bactris gasipaes Kunth) "in natura" sob refrigeração e atmosfera modificada / Preservation of Pupunha (Bactris gasipaes Kunth) hearts of palm "in natura" under refrigeration and modified atmosphere
This study aimed to quantify the respiratory rate, ethylene production and enzymatic activity of Pupunha hearts of palm and to determine the temperature for preserving the product, and to evaluate modified atmosphere packaging systems for product conservation. The first test aimed to quantify the respiratory rate and ethylene production of Pupunha hearts of

11. Evaluation of the effect of dry-film biocides on paint film preservation using neural networks
Biocides play an important role in the preservation of a variety of products susceptible to microbiological growth such as paint, a material that can undergo microbial deterioration both in storing (inside the can) and after the application on a surface. In this work, artificial neural networks were used to predict the level of fungal growth on surfaces pain

12. Conservação refrigerada de lima ácida "Tahiti" em combinação com atmosfera modificada, ácido giberélico e permanganato de potássio / Cold storage Tahiti lime in combination with modified atmosphere, gibberellic acid and potassium permanganate
Although Brazil is the largest producer and exporter of Tahitilime, actually, exports only 5% of total production. This is, in part, because of a lack of quality of these limes, characterized by loss of green skin colour after harvest. The purpose of this research was to evaluate the efficiency of modified atmosphere, gibberellic acid (GA) and potassium perm
