BACKGROUND AND AIMS Sinonasal cancers (SNCs) are rare neoplasms, accounting for about 3 % of head and neck cancers, with squamous cell carcinoma (SCC) and adenocarcinoma (ADC) as the most common subtypes. ADCs present strong associations with occupational wood dust exposure. Preventive measures have progressively reduced wood dust concentrations in workplaces but no study has evaluated the effe...

The visual appearance of seamless dyed edges of luxury leather goods represents a key issue in terms of quality grading since a high-quality leather has to be characterized by homogeneously coloured and shaped edges with uniform ink thickness. Despite a huge literature produced by scientific and technical community to automate many leather manufacturing processes, since leather patches are ofte...

The professional literature dealing with specific aspects of adhesive joints in the footwear industry is mainly devoted to procedures preparation, bonding and testing connection between upper sole material fashion sports footwear. However, there little research related requirements quality shoe parts. Safety occupational footwear, which intended for occupations such as firefighters, police offi...

In order to detect the defects in the leather sample in an automated way, the image of the leather sample has to be captured properly. To properly capture the images of the leather sample, we have implemented an auto exposure algorithm based on false position method which is discussed in this paper. This algorithm can also be used to properly expose the natural scenes

Leather industry is facing the consequences of their historic lack communication and now are under an increasing pressure to communicate position policies with regards corporate social responsibility (CSR), informing consumers about corporations’ good intentions actions recover clarity be able affirm without doubts that responsibly manufactured leather sustainable. Under this context, paper aim...

Looseness is defect that affects the quality of a significant proportion of leather, particularly bovine leather. This defect causes a wrinkled appearance on the leather surface and results in a significant reduction in the leathers value. The structural mechanism and causes of looseness in leather are not well understood; therefore this study aims to gain a better understanding of this. We hav...

A stable magnetic nanocomposite of collagen and superparamagnetic iron oxide nanoparticles (SPIONs) is prepared by a simple process utilizing protein wastes from leather industry. Molecular interaction between helical collagen fibers and spherical SPIONs is proven through calorimetric, microscopic and spectroscopic techniques. This nanocomposite exhibited selective oil absorption and magnetic t...

Tannery wastewater usually contains a high salinity due to the use of sodium chloride (NaCl) in curing and pickling. Although some no-pickle tanning and salt-free pickling technologies were developed, few of them have been widely used due to relatively poor mechanical and bulk properties of the resultant leather. Therefore, the role of NaCl in pickling and tanning should be elucidated in the fi...
