This research aim to assess the effect of absorption on the mechanical properties of sandstone rocks using a servo-controlled testing machine, stress-strain curves were obtained from which the uni-axial compressive strength, Young’s modulus and the brittleness index were measured for specimens prepared from a single block of Sandstone from the Hassi Messaoud site investigation, Algeria. To see how the strength properties were affected by changes in absorption content such as are likely to occur on site, the specimens were divided into three groups which were prepared for testing under different conditions of absorption equilibrium.

The purpose of study is to develop methods for damage prevention and production safety.

In this study, water aquifers in various districts of the Merlin Temple coal-mining area number 3-1 were examined using a fuzzy comprehensive evaluation. Using FLAC-3D software, a three-dimensional numerical model based on the geological conditions of the first mining area was built to produce a numerical simulation of the fissure-zone and caving development in the area.

The simulation results, together with the traditional empirical formula, were used to produce a contour map of the distribution of these characteristics. This enabled areas to be classified according to various safety factors.

On the basis of the water richness in the area, coal-roof aquifers and the safety factors of different districts, as well as comprehensive coal-roof water-flow conditions and their associated dangers could be better understood.

A zero-day vulnerability is a complimentary ticket to the attackers for gaining entry into the network. Thus, there is necessity to device appropriate threat detection systems and establish an innovative and safe solution that prevents unauthorised intrusions for defending various components of cybersecurity. We present a survey of recent Intrusion Detection Systems (IDS) in detecting zero-day vulnerabilities based on the following dimensions: types of cyber-attacks, datasets used and kinds of network detection systems.

Purpose: The study focuses on presenting an exhaustive review on the effectiveness of the recent IDS with respect to zero-day vulnerabilities.

Methodology: Systematic exploration was done at the IEEE, Elsevier, Springer, RAID, ESCORICS, Google Scholar, and other relevant platforms of studies published in English between 2015 and 2021 using keywords and combinations of relevant terms.

Findings: It is possible to train IDS for zero-day attacks. The existing IDS have strengths that make them capable of effective detection against zero-day attacks. However, they display certain limitations that reduce their credibility. Novel strategies like deep learning, machine learning, fuzzing technique, runtime verification technique, and Hidden Markov Models can be used to design IDS to detect malicious traffic.

Implication: This paper explored and highlighted the advantages and limitations of existing IDS enabling the selection of best possible IDS to protect the system. Moreover, the comparison between signature-based and anomaly-based IDS exemplifies that one viable approach to accurately detect the zero-day vulnerabilities would be the integration of hybrid mechanism.

The purpose of this study is to examine the effects of culture on the cross-cultural design of the recognition-based graphical password (RBG-P) interface as inferred from Chinese and Saudi subjects’ image selections.

The authors use a between-group design adopted using two groups of participants from China and the Kingdom of Saudi Arabia to measure the differences caused by the effects of cultures on graphical password image selections. Three hypotheses have been tested in a four-week long study carried out using two questionnaires and an RBG-P webtool designed for images selection.

The results have indicated that participants are equally biased not only toward their own culture but also depending on their opinions about other cultures. In addition, when creating the password, it has been observed that culture not only influenced the image selection to create the password but also have an effect on the sequence of the images forming the password.

Appropriately used image selection differences can be used appropriately in cross-cultural designs that will lead to better development of culturally adaptive interfaces that will boost the security posture of RBG-P authentication.

Some RBG-P interfaces that are produced outside the designer’s culture may suffer the effects of cultural differences. Hence, to incorporate culture in the interface, authentication systems within applications should be flexible by designing images that fit the culture in which the software will be used. To this end, access control interface testing should also be carried out in the environmental and cultural context in which it is will be used.

This paper provides useful information for international developers who develop cross-cultural usable secure designs. In such environments, the cross-culturally designs may have significant effects on the acceptability and adoption adaptation of the interface to multi-cultural settings.

This paper aims to focus on the most popular technique nowadays, the use of microwave irradiation in organic synthesis; in a few years, most chemists will use microwave energy to heat chemical reactions on a laboratory scale. Also, many scientists use microwave technology in the industry. They have turned to microwave synthesis as a frontline methodology for their projects. Microwave and microwave-assisted organic synthesis (MAOS) has emerged as a new “lead” in organic synthesis.

Using microwave radiation for synthesis and design of fluorescent dyes is of great interest, as it decreases the time required for synthesis and the synthesized dyes can be applied to industrial scale.

The technique offers many advantages, as it is simple, clean, fast, efficient and economical for the synthesis of a large number of organic compounds. These advantages encourage many chemists to switch from the traditional heating method to microwave-assisted chemistry.

This review highlights applications of microwave chemistry in organic synthesis for fluorescent dyes. Fluorescents are a fairly new and very heavily used class of organics. These materials have many applications, as a penetrant liquid for crack detection, synthetic resins, plastics, printing inks, non-destructive testing and sports ball dyeing.

The aim value of this review is to define the scope and limitation of microwave synthesis procedures for the synthesis of novel fluorescent dyes via a simple and economic way.

This paper aims to review how the metaverse influences and contributes to the halal industry, particularly focusing on halal logistics (HL), halal supply chain management (HSCM) and consumer behavior.

This paper analyzed scholarly studies to investigate existing literature and current as well as future trends in the adoption of the metaverse in HL, supply chains and consumer behavior. The study explores the thematic structure of the current knowledge landscape, identifies research gaps and highlights potential directions for future research at the intersection of the metaverse, supply chain and halal behavior. The authors identified 286 papers that examined the integration of the metaverse with HL practices, supply chain management strategies and consumer behavior in alignment with Islamic principles and standards.

The results indicate a limited number of studies on the successful adoption of the metaverse in HL, HSCM and behavioral research. This paper has proposed a framework for the metaverse-supply chain and halal behavior. The framework can serve as a reference for scholars and practitioners on how to incorporate advanced technology to engage with and predict market demand. Additionally, the metaverse-supply chain framework can be used to align with halal supply chain practices based on customer needs and preferences. The metaverse integrates the virtual world, enabling halal supply chain networks to enhance virtual reality, digital experiences and business performance.

The halal industry can showcase products and services through virtual scenarios, avatars and shops. By developing a halal-compliant metaverse, the halal industry can facilitate activities such as online sales, online payments and virtual marketing, thereby enabling a digital business transformation. Embracing the metaverse can improve business efficiency and influence consumer behavior, decisions and compliance with Shariah principles.

The authors argue that this paper is at the forefront and will serve as a reference for future research. This paper is distinct from existing literature, as it focuses on metaverse adoption and its correlation with a Shariah compliance framework in logistics, supply chain and behavioral aspects. Through its findings, this framework aims to inspire further empirical research and provide guidance and solutions to foster sustainable development in the halal industry.
