This paper aims to provide an overview of the recent developments and new topologies of single-phase moving magnet linear oscillating actuators (MMLOAs). The key advantage of the MMLOA when compared with conventional LOA is the absence of screws, gears and crankshaft mechanism, which results in fewer mechanical parts, simple structure, easy fabrication, lower noise levels and negligible frictional losses.

The review included papers up to August 2021. The structural designs of alternative topologies are deliberated in detail, and their relative merits and demerits are evaluated. Specific design issues, including pole and tooth number combinations, stroke length, magnet pole ratio and split ratio, are investigated. The imperative phenomena of the resonance, as well as the adjustable stroke, are also discussed in detail.

The electromagnetic performance in terms of thrust force of selected MMLOA topologies is compared. It is observed that the MMLOA with flux bridge topology has the highest thrust force of 365 N because of the large volume of the permanent magnets (PMs) used, which consequently increased the mass of the mover but based on overall performance analysis, single-phase end ferromagnetic Halbach surface-mounted PM LOA has the highest efficiency around 92%.

This review provides a comparative analysis for different tubular MMLOA topologies based on design construction and their electromagnetic performances.

This paper attempts to review the corporate voluntary disclosure (CVD) from the theoretical perspective as well as propose a conceptual framework.

The researchers use structural literature review technique. The sample literature consisting of 55 articles was extracted from the Scopus database over the period of 2017–2021.

The literature observes that the legitimacy, agency and stakeholder theories are most applied in CVD related studies than the other theories. It is also revealed that researchers need to concentrate more studies on those theories of CVD that have been applied in a limited study such as neo-institutional, signaling, resource dependence, political economy and impression management theories.

The findings can help the understanding of parties such as practitioners', regulators and potential investors of the theories in CVD from a combined and comprehensive view.

The results of the study offer new insights into the potential impact of organizational level and country level theories in CVD from different perspectives of developed and developing countries.

This study delivers an inclusive literature review of the current study approach on the theories of CVD and highlights some stimulating guidelines for future study.

The purpose of this work is to improve the air entrainment capacity of a concrete by using fine mineral admixtures such as fly ash (FA) and silica fume (SF) as cement substitute, and coal bottom ash (CBA) as fine aggregate substitute. Air entrainment capacity has been studied indirectly as a measure of heat resistance of concrete. Literature has suggested that mineral admixtures improve the air absorption in the paste component of the concrete, on the one hand, whereas they perform pore and grain size refinement, on the other, thereby reducing the air entrainment. CBA, which being porous, creates the possibility of air adsorption by the aggregate component. Therefore, the study finds out whether a double benefit of adding both of these materials will be achieved, or CBA will try to improve the deficiency in the air entrainment created by the mineral admixtures.

Air-entrained concrete (AEC) mixes were constituted in three groups. First group represents mixes with natural fine aggregates only, and second with 25% fine aggregates substituted by CBA. Progressively, the third group has 50% fine aggregates substituted with CBA. In all the three groups, cement was substituted with FA and SF @ 0%, 20% and 40%, and 0%, 5% and 10%, respectively, thereby creating four binary and four ternary mixes corresponding to each group. Compressive and flexural strength tests were conducted at 28 days on the concrete mixes pre and post high-temperature heat treatment, i.e. 100°C, 200°C and 400°C, respectively. This study also examines the microstructure characteristics of AEC after 14 days of curing via X-ray diffraction. Sorptivity test was also conducted to estimate the capillary and air-entrained voids in concrete.

It was found that a concrete mix containing 20% FA and 10% SF along with 50% CBA could give similar post-heated strength to a normal (without mineral admixtures) AEC. In AECs where only CBA is present and cement paste is not substituted, both of the pre- and post-heated strengths of concrete reduce. Also, some mixtures containing large amounts of mineral admixtures in concrete with nil CBA show a high reduction in post-heated strength though they show good pre-heated strength. Therefore, mineral admixtures and CBA complement each other in improving the post-heated strength. Air pore structure found from sorptivity test also verifies these results.

AEC is very helpful for insulation of buildings during summer season by absorbing heat waves. AEC containing FA and CBA reduces carbon footprint because of substitution of cement and it also helps to conserve natural resources by the use of CBA in place of fine aggregates.

This study aims to determine the effect of bank ownership on the credit risk of Indonesian Islamic local banks (ILBs).

This study uses the system generalized method of moments (GMM) estimation technique with a sample of 155 Islamic local banks in Indonesia from 2012 to 2019.

The results show that commissioner board (D.COW) ownership has a negative effect on credit risk. This indicates that an increase in the number of shares of Islamic local banks owned by the commissioner board reduces credit risk. On the other hand, government ownership (D.GOW), the Sharia supervisory board (D.SOW) and the director board (D.DOW) do not affect credit risk.

The government, Sharia supervisory board and director board need opportunities to easily own more Islamic local bank shares. Therefore, the provisions regarding the share ownership rights of the government, Sharia supervisory board and director board need to be improved to increase their role in reducing credit risk.

Previous researchers have not studied the effect of government ownership, the commissioner board, the Sharia supervisory board and the ownership of directors on credit risk at the ILB in Indonesia.

Using discarded tyre rubber as concrete aggregate is an effective solution to the environmental problems associated with disposal of this waste material. However, adding rubber as aggregate in concrete mixture changes, the mechanical properties of concrete, depending mainly on the type and amount of rubber used. An appropriate model is required to describe the behaviour of rubber concrete in engineering applications. The purpose of this paper is to show how a new evolutionary data mining technique, evolutionary polynomial regression (EPR), is used to predict the mechanical properties of rubber concrete.

EPR is a data‐driven method based on evolutionary computing, aimed to search for polynomial structures representing a system. In this technique, a combination of the genetic algorithm and the least square method is used to find feasible structures and the appropriate constants for those structures.

Data from 70 cases of experiments on rubber concrete are used for development and validation of the EPR models. Three models are developed relating compressive strength, splitting tensile strength, and elastic modulus to a number of physical parameters that are known to contribute to the mechanical behaviour of rubber concrete. The most outstanding characteristic of the proposed technique is that it provides a transparent, structured, and accurate representation of the behaviour of the material in the form of a polynomial function, giving insight to the user about the contributions of different parameters involved. The proposed model shows excellent agreement with experimental results, and provides an efficient method for estimation of mechanical properties of rubber concrete.

In this paper, a new evolutionary data mining approach is presented for the analysis of mechanical behaviour of rubber concrete. The new approach overcomes the shortcomings of the traditional and artificial neural network‐based methods presented in the literature for the analysis of slopes. EPR provides a viable tool to find a structured representation of the system, which allows the user to gain additional information on how the system performs.

The purpose of this paper is to evaluate the prevalence and antibiograms of bacteria isolated from various fresh fruit juices at a local market in Faisalabad.

Fresh fruit juice samples (n=125) were randomly collected using aseptic technique. Each sample (10 mL) was serially diluted with 90 mL of sterile peptone water, from 1×10⁻¹ to 1×10⁻⁵. Each dilution was then used to inoculate nutrient agar by surface spread plating. Aerobic colony counts (ACCs) were determined by colony counting. The isolates were sub-cultured on blood and MacConkey agar. Preliminary identification was achieved on the basis of colony morphology and culture characteristic, and confirmed by API® 20E, 20NE, and API® Staph testing. Antimicrobial susceptibility testing was carried out using the Kirby-Bauer disk diffusion assay, per CLSI 2015 guidelines.

The mean ACC ranged from 2.0×10⁶ CFU/mL to 4.93×10⁶ CFU/mL, with the highest ACC determined for orange juice. Overall, 153 polymicrobial were identified in 125 samples; 103 of these were Gram-negative rods (GNR) and 28 were Gram-positive cocci (GPC). Escherichia coli (n=38), Klebsiella pneumoniae (n=32) and Pseudomonas aeruginosa (n=24) were the predominant GNR; Staphylococcus aureus (n=28) was the predominant GPC. Antibiogram analysis revealed that all GNR were resistant to ampicillin. However, most E. coli isolates were resistant to ceftazidime (72.4 percent of isolates), and ceftriaxone and cefepime (68.9 percent), while most K. pneumoniae isolates were resistant to cefepime (72 percent) and ceftriaxone (64 percent). All S. aureus isolates were resistant to penicillin, while most (64 percent) were resistant to piperacillin; the most effective drugs against bacteria were vancomycin and imipenem.

The findings suggest that the local government regulatory food and public health authorities should take immediate emergency measures. Appropriate surveillance studies and periodic monitoring of food items should be regularly performed to safeguard public health.

The current study revealed the prevalence of multidrug-resistant bacteria in freshly prepared fruit juices sold by local street vendors.

The purpose of this study is to assess the impact of mobile phone usage on sales and profit as the indicator of business performance, to analyse the facilitating roles of mobile phones and factors affecting farmers' decision to use the mobile phone in agribusiness activities.

Intensive farming was selected in this study due to its higher profitability than other crops. Data were compiled from field surveys of 1,040 farmer households in vegetable production regions of Indonesia. This study employed structural equation modelling, identifying mediating variables and quantifying multiple endogenous variables' direct and indirect effects in simultaneous regression equations.

The results indicate that mobile phone usage enabled farmers to increase sales, obtain market information, acquire improved agronomic technology, access credit and contact customers. The device enhanced profit through mediations of high sales, reasonable prices and access to credit and market information. The personal attributes of farmers determined the adoption of mobile phones to support agribusiness activities.

This study paid attention to the use of mobile phones, which was considered an integral technology of information and communication. Other components, such as personal computers and other Internet-based devices, need further study.

As the rate of mobile phone use was still low, farmers should be encouraged to utilise the device. Socialisation and specially designed training workshops on agribusiness information systems using mobile phones are of the best ways.

Using structural equation modelling enables to analyse of multi-dependent variables in one model. Farm-level data provide a real situation, and policy implications should address the right target. The subject of this investigation is a semi-subsistence farm household that lacked access to information and communication technology.

The shift in consumer focus towards green marketing mix elements is not a unique thing. Especially in recent times, most organizations are trying to implement green marketing strategies in order to influence customers as well as to reduce the negative impacts of environmental footprints. However, in recent times service marketing requires thorough implementation of a Green Marketing Mix as evidenced by Asian countries. However, research also claims that the use of a traditional green marketing mix is not a guarantee of success in the long run and therefore has been criticized by several researchers and scholars. Hence, there is a need to follow the Green-SIVA (Solution, Information, Access, and Value) concept in order to create a long-lasting impact on consumer buying and to discuss the application of tools in a more comprehensive manner. Although the linkage of Green-SIVA marketing might provide a new way to develop an effective marketing mix strategy for services. Hence, this chapter has been written purposely to discuss GMM elements with reference to the service industry of Pakistan and tries to develop an association with green-SIVA marketing practices in order to optimize service marketing practices.

Facility design standardization strategy has considerable advantages, highlighted by its widespread and consistent use in the shipbuilding and manufacturing industries. However, capital projects have failed to realize these benefits. The primary rationale behind this problem is the lack of proper understanding of design standardization, more specifically the benefits and equally importantly, the trade-offs of design standardization in capital projects. Therefore, this study highlights 13 benefits and six trade-offs of standardization in connection to design standardization, along with specific examples.

To achieve the study objectives, the researchers identified the most impactful benefits and trade-offs in terms of economic impact by surveying prominent players in the industry. Furthermore, the researchers examined 43 actual case projects (a case study) executed with the standardization strategy to evaluate the industry's status in terms of the levels of advantage achievement and disadvantage incurrence.

The results of this survey show that design once, reuse multiple times and design and procurement in advance are the most impactful benefits. Similarly, susceptible to changes in the market conditions is one of the top trade-offs that can be incurred in capital projects when implementing standardization. The results also highlight that design once, reuse multiple times is one of the most achieved benefits in standardized capital projects today, while cost of establishing the design standard is the most incurred trade-off.

This study provides important insight into how standardization strategy can be advantageous while also enriching the literature about pitfalls expected from standardization. Moreover, this study's results will help the industrial sector achieve higher levels of design standardization by providing a better understanding of the benefits and trade-offs of design standardization.
