Modeling Online Student Engagement Using Social Cognitive Theory

This study applied social cognitive theory to investigates the influence of personal and environmental factors on student engagement (concerning the behavioral, emotional, and cognitive engagement dimensions) and, in turn, perceived learning and student satisfaction (as outcomes) in the online learning environment. The study explored the perceptions of Egypt’s higher education students with regard to their engagement, learning, and satisfaction with their online learning experience

"Hanging Rugs between Aesthetic Value of Flowers and Design Software"

The art of wall hanging textiles has become one of the highly valued artistic and aesthetic applied arts in civilized societies. It is an important method for decorating public buildings and houses, which covers a large areas of walls. The success of wall hanging rugs industry depends on the designer's ability on successful innovation in which he exploits his culture, imagination and skills in producing rugs characterized by beauty with performance efficiency, to access a high level of quality that impose their efficiency in the market competition. Design is considered one of the most important factors that helps to attract the customer and promote the product economically.Human use nature as a rich source of colors, lines and forms. It is rich in relations that correlate between elements in aesthetic expressive formations. The good artist is the one who has the ability to meditate the nature and distinguish the beauty in its relations. Many artists have created great artworks inspired by the simplest elements in nature such as flowers and plants of all kinds.With the entry of Egypt the free trade era, we had to look for methods to develop the rugs designs and enhance their aesthetic value through looking for a new source of design resources by natural flowers processing using design software such as Photoshop and Illustrator to produce authentic and innovative designs that provides the principles of a successful design such as diversity, balance, unity, rhythm. These designs will be implemented using hand-tufted carpets style.The research problem can be summarized in the predominance of the representative style in hanging rugs design derived from natural flowers and the need of presenting modern trends in the field of hanging rug designs.The research aims to get benefit of the design software in designing of hanging rugs from designs inspired by natural flowers.In this research, a group of hanging rug designs have been made by employing the design software to create designs inspired by natural flowers, and then implemented using the hand tuft

Recent Advances in Functionalization of Cotton Fabrics with Nanotechnology

Nowadays, consumers understand that upgrading their traditional clothing can improve their lives. In a garment fabric, comfort and functional properties are the most important features that a wearer looks for. A variety of textile technologies are being developed to meet the needs of customers. In recent years, nanotechnology has become one of the most important areas of research. Nanotechnology’s unique and useful characteristics have led to its rapid expansion in the textile industry. In the production of high-performance textiles, various finishing, coating, and manufacturing techniques are used to produce fibers or fabrics with nano sized (10−9) particles. Humans have been utilizing cotton for thousands of years, and it accounts for around 34% of all fiber production worldwide. The clothing industry, home textile industry, and healthcare industry all use it extensively. Nanotechnology can enhance cotton fabrics’ properties, including antibacterial activity, self-cleaning, UV protection, etc. Research in the field of the functionalization of nanotechnology and their integration into cotton fabrics is presented in the present study

Fabrication of New Multifunctional Cotton/Lycra Composites Protective Textiles through Deposition of Nano Silica Coating

This study aims to develop multifunctional pile cotton fabrics by implementing different compositions of lycra yarns with different densities of the cotton fabric under study. Highly dispersed silica nanoparticles (SiO2 NPs) with small sizes—in the range of 10–40 nm—were successfully prepared and were analyzed using scanning electron microscopy (SEM). The particle size distribution of nano silica was determined via dynamic laser scattering (DLS) and measurements of its zeta potential. Cotton/lycra fabrics were treated using prepared SiO2 NPs in presence of ethylenediaminetetraacetic acid (EDTA) as a crosslinking agent. Energy dispersive X-ray (EDX) analysis and scanning electron microscopy (SEM) were used to characterize the nano-treated fabrics and assure homogeneous dispersion of SiO2 NPs on the cotton/lycra composites. Additionally, the nanoparticles were screened for their in vitro antibacterial activity against human pathogens such as Gram-positive Staphylococcus aureus and Bacillus cereus and Gram-negative Escherichia coli and Pseudomonas aeruginosa strains. The functional properties of the new composite pile cotton fabrics include excellent antibacterial, highly self-cleaning, and excellent UV protection factor (UPF) properties
