The industrial training component in a university's curricula adds tremendous value to a degree programme by enhancing the employable skills of graduates. The purpose of this paper is to assess the perception of organisations that have trained construction students from the Department of Building Technology of the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, as part of its industrial training programme.

Through a structured questionnaire survey of 120 organisations which have offered industrial training to construction students in the Accra, Kumasi and Cape Coast metropolitan areas of Ghana, the paper assessed industry's views on issues relating to the nature and objectives of industrial training, preparation towards training, performance of students during training, effectiveness of the training and areas of improvement. Data collected through the survey were analysed using largely descriptive statistics and content analysis.

In the opinion of the training organisations, industrial training exposes students to real work environment and helps them to apply theory to practice. During industrial training, the trainees showed high level of performance achievement in their ability to carry out instructions, ability to function as team players and ability to apply knowledge gained from the university among others. However, they showed a low level of performance achievement in negotiation skills, independence, social and multi‐racial awareness and ability to make decisions. Major areas requiring improvement in the way industrial training is currently organised include: the need for learning institutions to provide guidelines for industrial training for use by host organisations and to monitor trainees during industrial training; training organisations should design training programmes which emphasise all competencies, appoint industrial supervisors and submit industrial feedback to learning institutions.

The findings from the study will not only make industrial training programmes in Ghana and other developing countries more effective and successful towards the improvement of skills of trainees and thereby increase their chances of employment after graduation but also provide a reliable source of highly skilled and educated workers and an expanded pool of qualified future employees.

The paper provides a basis for enhancing and developing effective IT practices as well as providing indicators for evaluating existing IT practices in Ghanaian and other universities in developing countries to positively influence future employees of the construction industry.

The metal working fluid industry accounts for approximately 5 per cent of the total world market for lubricant. Cutting fluids are formulated to fulfil one or more different functions. It is becoming increasingly apparent that to provide additions friendly for environment and low costs. This paper studies high performance mixture of anionic/nonionic polymeric surfactants as an additive for metal working fluid, thus the mixture has poly functions such as anticorrosion and emulsifier. The surface tensions of aqueous solutions of anionic/nonionic mixtures were measured as a function of nonionic concentration at 40°C with constant anionic concentration. The surface excesses concentrations, mole fractions, and interaction parameters of binary polymeric mixtures were calculated. Moreover, the critical micelle concentration and adsorption of ANO/ETH mixture on solutions and steel surface were determined. These parameters confirm the synergistic action of ANO/ETH polymeric surfactants for micellization and adsorption at different interfaces.

In defining microcelebrity, media technologies are often described as integral to the self-branding process. This chapter argues that social network platforms are not social utilities, but, in fact, celebrification utilities. That is, they are programmed to necessarily brand users by extracting and filtering identifications to be easily consumed by advertisers, just as microcelebrities promote specific, “authentic” aspects of self that can be easily consumed by fans. Through a discourse analysis of Facebook’s functionalities and in-depth interviews with 45 emerging adults, I present an analysis of microcelebrity culture through the narratives of everyday users who are not actively involved in self-branding but are instead compelled by the site’s inherent design to unintentionally brand – they unknowingly align with corporation-like mission statements; ignore multiple, dynamic selves; and discard their right to anonymity.

The purpose of this study is to inspect the corrosion inhibition of API N80 steel pipelines in uninhibited solution and inhibited with a synthesized surfactant compound [N-(3-(dimethyl octyl ammonio) propyl) palmitamide bromide] (DMDPP), which is prepared through a simple and applicable method.

Weight loss was inspected at five different temperatures of 25°C, 30°C, 40°C, 50°C and 60°C Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation were used at room temperature. Density functional theory was used to study the relation between the molecular structure and inhibition theoretically.

Adsorption of the prepared DMDPP fits the Langmuir isotherm model. The inhibition efficiency of the prepared DMDPP amphipathic inhibitor is directly proportional to temperature increase. Polarization results reveal that the investigated DMDPP amphipathic compound behaves as a mixed-type inhibitor. EIS spectra produced one individual capacitive loop.

The originality is the preparation of cationic surfactants through a simple method, which can be used as corrosion inhibitors in oil production. The synthesized inhibitors were prepared from low-price materials. The work studied the behavior of the synthesized surfactants in inhibiting the corrosion of the steel in an acidic medium. Electrochemical and theoretical studies were presented, besides gravimetric and surface examination.

The purpose of this study is to examine and review tayyiban indicators in the context of halal food production. In Islam, food produced or manufactured must be halal and tayyiban. Even though both halal and tayyiban are always mentioned together in the Quran, the halal aspect is highlighted more than tayyiban. The discussion of tayyiban’s indicators is still vague.

The study was adopted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the review of the current research which used two main journal databases, namely, Web of Science and Scopus. Accordingly, the search resulted in a total of 40 articles that can be systematically examined.

The results of review of these articles formulated five main themes: safety, nutrition, cleanliness, quality and authenticity. These five indicators are considered relevant enough in the context of halal food production to build a comprehensive tayyiban concept.

This study enriches the field of halal food research. The concept of tayyiban as a whole has been given limited attention in academic literature. At the end of this study, a number of recommendations are suggested for the reference of future scholars.

The inhibiting effect of cationic surfactant N, N, N‐dimethyl 4‐methylbenzyl dodecyl ammonium chloride on mild steel in hydrochloric acid solutions was investigated by surface and thermodynamic measurements, weight loss tests, polarization measurements and EDS techniques. The data obtained from surface and thermodynamic measurements with the inhibitor indicate that the area per molecule slightly increases with increasing temperature and both absorption and micellization processes are spontaneous. Weight loss measurement showed that the inhibition efficiencies increased with increasing surfactant concentration and attained a maximum around their critical micelle concentration. Polarization studies reveal that the inhibitor behaves as a mixed type in hydrochloric acid solutions and acted on the cathodic reaction without modifying the mechanism of the hydrogen evolution reaction. EDS measurement showed high coverage of surfactant on the mild steel surface.

Modern cutting fluids often are real aqueous solutions of chemical compounds. That form of cutting fluid is simpler in preparation, as compared to emulsions and microemulsions. The water base is a good cooling medium of high‐ecological value. The purpose of this paper is to discover water‐soluble additives that could improve the lubricity of water.

Three cationic surfactants were chosen to be analyzed. Their tribological properties were verified using two testers: T0‐2 (four‐ball machine) and T‐11 (ball‐on‐disk). The results of the tests performed using friction couples made of steel (T0‐2, T‐11) and steel‐ceramics (T‐11) were satisfactory.

The friction coefficients and wear scar diameters are even a few times smaller, as compared to the ones measured in a water environment.

The paper demonstrates that the crucial role in improvement of the tribological properties is played by the surface activity of the additives (confirmed by the measurements of the surface tension and wetting angle). As the cationic surfactants are bactericidal and anti‐corrosive, they can be classified as multi‐purpose additives modifying water lubricity.
