To authenticate an image using a hash function is a challenging task since several core issues like tamper detection, security and robustness needs to be addressed. In this paper, we propose a hash-based image authentication scheme that simultaneously attempts to address these core issues. Unlike most of the existing schemes that use secret key in the feature extraction stage, we use secret key to randomly modulate image pixels to create a transformed feature space. The key-dependent transformed ...

Objective: In this study, we investigated the efficacy and safety of remdesivir and tocilizumab combination therapy against dexamethasone for the management of severe COVID-19 patients. Methods: This was a multicenter study. Cases were randomly chosen and divided into two groups using an odd–even ratio of 1:1 applied to the hospital registration number. Group A received remdesivir [5 mg/kg (<40 kg) or 200 mg (>40 kg) on day 1 and then 2.5 mg/kg (<40 kg) or 100 mg (>40 kg) daily] + tocilizumab [8 ...

Aspergilloma is a saprophytic infection that colonizes pre-existing lung cavities. Typically, aspergilloma develops in cavities formed as a result of diseases such as tuberculosis, sarcoidosis, bronchiectasis, lung abscess and cavitatory neoplasia. Coexistence of fungi with a pulmonary echinococcal (hydatid) cyst is seen more commonly in immunocompromised patients. Although aspergilloma has occasionally been described in operated hydatid cyst cavities, only one case has been reported previously in ...

The situation of elderly people is an increasingly pressing global concern. This issue is especially challenging for developing countries, where, traditionally, the majority of the elderly people have lived with their family and have been dependent on family support. Nowadays, however, appropriate family support is no longer guaranteed. An assessment tool for measuring active family support would be useful for describing the real living situation of the elderly. The purpose of this study was to ...

3D printing (3DP) is one of the modern approaches in the field of manufacturing. Although this process has been known for a fair amount of time, only the more-recent developments have revealed its potential for applications in different manufacturing sectors. Textiles, one of the basic human requirements, does more than just fulfilling the fundamental necessity of covering the body. Integrating 3DP technology in textiles has broadened the horizon of the textile world. This review explores the historical ...

The textile wet processing industry is considered a notorious polluter due to its widespread use of natural resources without proper replenishment. Bangladesh is one of the largest producers of textile products in the World, and therefore, it is vulnerable to environmental degradation. Bangladesh is predominantly a cotton processing country; therefore, reactive dyes are commonly used, and the dye combination is very water and chemical-intensive. There is a scarcity of information on the consumption ...

Such clothing is predominantly single-use, made of plastic-based synthetic fibers such as polypropylene and polyester, low cost and able to provide protection against pathogens. However, the environmental impacts of synthetic fiber-based clothing are significant and well-documented. Despite growing environmental concerns with single-use plastic-based protective clothing, the recent COVID- ...

Abstract Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high‐performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco‐friendly composite. This ...

Every informed measure must be taken to stop its spread, bring down number of new infections and move to normalization of daily life. Contemporary research has not identified waste management as one of the critical transmission vectors for COVID‐19 virus. However, most underdeveloped countries are facing problems in waste management processes due to the general inadequacy and inability of waste management. In ...

In seeking to identify alternative low freshwater‐usage coloration technology, this study examined the potential use of seawater ( SEAW ) as the dyeing medium for wool coloration using a range of reactive dyes. Initially, the dyeing behaviour of the wool fabric in simulated seawater ( SSW ) was compared with conventional dyeing from distilled water ( DW ) using α‐bromoacrylamide‐based Lanasol dyes and sulphatoethyl ...

The effects of compositional variation on porosity, coercivity, remanence, saturation magnetisation, magnetic moments, and Y–K angles are reported. The coercivity exhibits almost similar behaviour to that of porosity, whereas, the remanence decreases with increasing Zn-content. The saturation magnetisation and magnetic moments exhibit decreasing behaviour ...
