"Hanging Rugs between Aesthetic Value of Flowers and Design Software"
No full textThe 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
Modeling Online Student Engagement Using Social Cognitive Theory
No full textThis 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
ANALYZING TOURIST SENTIMENT AND TOPICS IN MALAYSIAN DESTINATION TWEETS: INSIGHTS FOR SUSTAINABLE TOURISM MANAGEMENT IN PENANG
No full textThis research aims to analyse the opinions expressed in tweets about a tourism destination in Malaysia and elucidate the dominant topics discussed on Twitter. This study analyses tourist sentiment on a Malaysian destination from a sustainability perspective by examining tweets using Lexicon-based sentiment analysis for polarity detection and Latent Dirichlet Allocation (LDA) for topic modelling. A total of 18,018 tweets about Penang Tourism revealed that 46% of sentiments were positive, 39% were neutral, and 15% were negative. Tourists primarily discussed food, tourist spots, events, hotels, traffic, and driver attitudes. Core tourism services received positive feedback, whereas additional fees were noted as less favourable. These insights provide useful information for policymakers and businesses to understand tourist behaviour and expectations, supporting sustainable tourism practices and resource management
Recent Advances in Functionalization of Cotton Fabrics with Nanotechnology
No full textNowadays, 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
TOURIST VOICES ON TWITTER: SENTIMENT AND TOPIC ANALYSIS FOR SUSTAINABLE TOURISM IN PENANG
No full textThis research aims to analyse the opinions expressed in tweets about a tourism destination in Malaysia and elucidate the dominant topics discussed on Twitter. This research examines tourist sentiment on a Malaysian destination from a sustainability perspective by analysing 18,018 tweets, collected from November 9, 2021, to January 9, 2022, using Lexicon-based sentiment analysis for polarity detection and Latent Dirichlet Allocation (LDA) for topic modelling. Results revealed that 46% of sentiments were positive, 39% were neutral, and 15% were negative. Tourists primarily discussed food, tourist spots, events, hotels, traffic, and driver attitudes. Core tourism services received positive feedback, whereas additional fees were noted as less favourable. The integration of sentiment analysis and LDA enables a nuanced understanding of tourist experiences, providing actionable insights for policymakers and businesses to enhance sustainable tourism practices and optimize resource management in Penang
Fabrication of New Multifunctional Cotton/Lycra Composites Protective Textiles through Deposition of Nano Silica Coating
No full textThis 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

A novel non-canonical PIP-box mediates PARG interaction with PCNA
No full textPoly(ADP-ribose) glycohydrolase (PARG) regulates cellular poly(ADP-ribose) (PAR) levels by rapidly cleaving glycosidic bonds between ADP-ribose units. PARG interacts with proliferating cell nuclear antigen (PCNA) and is strongly recruited to DNA damage sites in a PAR- and PCNA-dependent fashion. Here we identified PARG acetylation site K409 that is essential for its interaction with PCNA, its localization within replication foci and its recruitment to DNA damage sites. We found K409 to be part of a non-canonical PIP-box within the PARG disordered regulatory region. The previously identified putative N-terminal PIP-box does not bind PCNA directly but contributes to PARG localization within replication foci. X-ray structure and MD simulations reveal that the PARG non-canonical PIP-box binds PCNA in a manner similar to other canonical PIP-boxes and may represent a new type of PIP-box. While the binding of previously described PIP-boxes is based on hydrophobic interactions, PARG PIP-box binds PCNA via both stabilizing hydrophobic and fine-tuning electrostatic interactions. Our data explain the mechanism of PARG–PCNA interaction through a new PARG PIP-box that exhibits non-canonical sequence properties but a canonical mode of PCNA binding.© The Author(s) 201
