CF6–50A engines have been selected to power the European A300B aircraft scheduled for certification and airline delivery in 1974.

The materials included in this column were selected on the basis of an item by item review of all government publications received at a major depository library. Emphasis is placed on tools of a reference format, although much else that the Federal government publishes is otherwise of high referral value. Publications not in a reference format, in the strictest sense, are included when their potential value dictates; brief entries for “how to” items and informative pamphlets are also given if deemed potentially useful, particularly for school and public libraries and wherever the identification of vertical file materials is the responsibility of the public service librarian.

This study is centered on the identification of the most appropriate Technology Adoption (TA) model for investigating the adoption of Industry 4.0 technologies within pharmaceutical and related enterprises. The aim is to facilitate a smooth transition to advanced technologies while concurrently achieving environmental sustainability.

Selection of a suitable TA theory is carried out using a hybrid multi-criteria decision-making (MCDM) approach incorporating PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA) and Fuzzy Measurement of alternatives and ranking according to Compromise solution (F-MARCOS) methods. A group of three experts is formulated for the ranking of criteria and alternatives based on those criteria.

The results indicate that out of all six TA models considered unified theory of acceptance and use of technology (UTAUT) model gets the highest utility function value, followed by the technical adoption model (TAM). Further, sensitivity analysis is conducted to confirm the validity of the MCDM model employed.

Challenging times like COVID-19 pointed out the importance of technology in the pharmaceutical and healthcare sectors. TA studies in this area can help in the identification of critical factors that can assist pharmaceutical firms in their efforts to embrace emerging technologies, enhance their outputs and increase their efficiency.

The novelty of this research lies in the fact that the utilization of a TA theory prior to its implementation has not been witnessed in existing scholarly literature. The utilization of a TA theory, specifically within the pharmaceutical industry, can assist enterprises in directing their attention toward pertinent factors when contemplating the implementation of emerging technologies and achieving sustainable development.

This paper aims to analyse the Sharī'ah premises of classical waqf doctrines followed by critically analysing the framework of waqf jurisprudence (fiqh al-awqāf) from a Maqāṣid al-Sharī'ah (the higher objectives of Islamic law) perspective. The objective of examining the jurisprudential framework of waqf from a maqāṣid perspective is to contextualise the scope of dynamism and innovation in the modern waqf structure.

For examining the jurisprudential aspects of classical fiqh al-awqāf with a special reference to Maqāṣid al-Sharī'ah, the paper analyses the classical waqf books and treatises from the four Sunni schools of jurisprudence by employing a textual analysis method.

The paper finds that the key constituents of maqāṣid are interwoven in the classical discourse of waqf rulings. It finds that in deriving the principles of waqf, the jurists ensured that the essentialities of Maqāṣid al-Sharī'ah are subtly intermingled with the necessary components of fiqhī principles. Deconstructing the applied analogical reasoning of the classical jurists in deriving the waqf rulings, this paper provides recommendations for maqāṣid-oriented application of waqf in the modern context.

This study does not cover either the historical contribution of waqf among the Muslim societies nor does it touch on the empirical aspects of modern waqf. Rather, the focus of the study is limited to analysing the classical jurisprudential rulings of waqf and their distillation process from a Maqāṣid al-Sharī'ah perspective. The study has good implication for modern awqāf, which need to be created, managed and directed in the spirit of Maqāṣid al-Sharī'ah.

The key objective of adopting the maqāṣid framework for the analysis of fiqh al-awqāf in its classical permutations is to learn how to utilise the maqāṣid approach as a baseline for the deduction of new waqf rulings in a contextualised term.

The novelty of the paper lies in its examination of the classical waqf rulings distillation process, and the cogent intersection of Maqāṣid al-Sharī'ah with the principles of fiqh. By delving into the Sharī'ah premises of classical waqf jurisprudence through the lens of maqāṣid, the paper adds an original value and fills an existing gap in the available literature.

The purpose of this paper is to develop a hierarchical model to rank the challenges faced by the private Malaysian higher education institutions (HEIs) in the provision of quality education and subsequently their corresponding critical success factors (CSFs) to address those challenges.

A sequential mix method was adopted in this study. Semi-structured interviews with 29 participants were initially conducted to identify the challenges and CSFs. This was followed by a questionnaire survey involving 158 respondents to prioritise the identified findings. Thematic analysis was conducted in the qualitative stage, uncovering the challenges and their corresponding CSFs. Data for both stages were accumulated from internal and external stakeholders of Malaysian private HEIs. Finally, the four stages of the analytic hierarchy process (AHP) were applied to rank the challenges and CSFs.

The qualitative stage identified eight challenges, i.e. “academics”, “facilities”, “students”, “programmes and curriculum”, “competition”, “accreditation”, “finance” and “research” together with their corresponding CSFs. The AHP enables the ranking of these challenges. “Finance” has been found to be the most crucial challenge and “high competency in managing the institution’s finance” as the most important CSF to address this challenge.

As the study restricted its focus on Malaysian private HEIs, the results may not be generalised for public HEIs and foreign private HEIs operating in Malaysia.

The hierarchical model developed in this study is deemed important for implementation to resolve the prioritised challenges. It spells out the specific areas in which the resources of Malaysian private HEIs need to be prudently disbursed and properly managed.

IN this part we shall consider the effect of non‐uniformity (with respect to k) in the longitudinal members, with particular reference to the case of four longerons, and we shall then go on to discuss the treatment of cut‐outs.

This annotated listing of 125 United States Government bibliographies is the first annual supplement to BIBLIOGRAPHY OF UNITED STATES GOVERNMENT BIBLIOGRAPHIES 1968–1973 (Pierian Press). Most publications included bear a 1974 imprint, though there are some with earlier imprints which are not included in the 1968–1973 BIBLIOGRAPHY.

In comparison to other industries, the construction industry is one of the most dangerous industries. Behavior-based safety (BBS) is a common and useful technique for risk indicator processing. Almost all studies are based on the BBS checklist, but very few of them focus on the increasing dangers faced by construction workers and the important factors that lead to accidents. This research represents a risk spatiotemporal analysis and visual tracking approach based on BBS and Building Information Modeling (BIM).

After the literature review, a BBS checklist was developed. Then a survey was conducted based on the BBS checklist and the temporal evolution of risks has been completed. After that, managing the risk with the automatic rule checking (ARC) system using BIM was conducted simultaneously to develop a framework by conducting a case study.

Based on the grey clustering analysis, this work provides a temporal evolution analysis approach for dynamic analyzing BBS risk. According to the grey relational analysis (GRA) data, the main key factor of risk was the missing guardrail/handrail system. After that, a case study was performed and the system automatically warn in the preconstruction phase that the barrier is missing as the system benefits.

A systematic framework has been provided for risk analysis through which high health and safety performance outcomes can be achieved on construction projects. This study will assist design engineers in addressing the potential danger to employees during the preconstruction stage and monitoring dynamic changes in risk on any construction site.

The purpose of this study aims to synthesize a novel donor–acceptor dye based on phenothiazine as a donor (D) and nonconjugated spacer was devised and synthesized by condensing of 2,2'-(1H-indene-1,3(2H)-diylidene) dimalononitrile with aldehyde and the practical synthesis methodology as given in Scheme 1.

The prepared phenothiazine dye was systematically experimentally and theoretically examined and characterized using nuclear magnetic resonance spectroscopy (1H,13C NMR), Fourier-transform infrared spectroscopy (IR) and high-resolution mass spectrometry. Density functional theory (DFT) and time-dependent density functional theory DT-DFT calculations were implemented to determine the electronic properties of the new dye

The UV-Vis absorption and fluorescence spectroscopy of the synthesized dye was investigated in a variety of solvents with varying polarities to demonstrate positive solvatochromism correlated with intramolecular charge transfer (ICT). The probe’s quantum yields (Фf) are experimentally measured in ethanol, and the Stokes shifts are found to be in the 4846–9430 cm⁻¹ range.

The findings depicted that the novel (D-π-A) chromophores may act as a significant factor in the organic optoelectronics.
