To investigate the capability of a series of nitrogen‐based heterocyclic organic compounds in inhibiting corrosion of iron in HCl and elucidate the dominant active form of the applied compounds during the adsorption process to explore the mechanism of their action.

The tested compounds were pyrimidine containing compounds, which were selected, based on molecular structure considerations. Gravimetric method has been applied with various electrochemical techniques (polarisation resistance, polarisation curves and electrochemical impedance spectroscopy) to investigate inhibition efficiency and mechanism.

The inhibiting action of the investigated pyrimidine containing compounds depends primarily on their concentration and molecular structure. These compounds act as mixed type inhibitors and function via adsorption on the surface, which follows Frumkin adsorption isotherm. The inhibition by the tested pyrimidine derivatives could be attributed to their chemisorption on the metal surface forming donor/acceptor type of bond between the inhibitor molecules and the vacant d orbitals of the surface iron atoms. Contribution from electrostatic adsorption, via interaction between the protonated form of the inhibitor and the charged metal surface, is also possible.

The applied inhibitors were tested in the presence of chloride ions as a corrosive medium. Whether these inhibitors will function well in the presence of other ions that are typically present in natural corrosive environment is unknown.

This paper provides useful information regarding inhibition effect of pyrimidine and series of its derivatives. The outcome of this work contributes to better understanding of the mechanism of inhibition by this class of N‐based heterocyclic organic compounds.

Digital preservation requires new skills and collaboration among library staff to maintain long-term access to information resources. Digital content and digital technologies pose a serious challenge to information institutions to continue to select, preserve and access information resources. However, there is an urgent need to increase awareness of the new trends in the partnership between research communities and academic libraries; there is also a need for new digital preservation-related skills among librarians. Therefore, this research aims to investigate the benefits, importance, requirements and challenges of digital preservation in academic libraries in Jordan.

A questionnaire was disseminated to 150 library staff working at the 10 public universities in Jordan, with 133 questionnaires suitable to analyze with a response rate of (88.6%).

The results indicate a moderate perception of the benefits and importance of digital preservation, as well as the requirements and challenges in academic libraries in Jordan to carry out the digital preservation process. This indicated the importance of increasing the academic libraries' – specifically academic libraries in Jordan – awareness of the vast and important benefits of digital preservation to maintain long-term access to information. It was noted that factors such as sex, experience, educational level and specialization did not affect the results.

The findings will provide insights for other academic libraries on how to plan and develop preservation policies to maintain access to information.

Access to information is a human right that contributes to the advocacy of sustainable development, and hence, digital preservation can facilitate long-term availability and accessibility to information.

This paper provides insights and practical solutions for academic libraries in response to technological development and the change requirements. It will help academic libraries handle and cope with the challenges of providing distance library services over digital channels.

The purpose of this paper is investigate the inhibition efficiency of three similar bi-cyclic organic compounds, namely, benzimidazole (BI), benzotriazole (BTAH) and benzothiazole (BTH) on carbon steel in 1 M hydrochloric acid (HCl) solution. Organic inhibitors are widely used to protect metals in acidic media. Among abundant suggestions for acid corrosion inhibitors, azole compounds have gained attention.

The inhibition efficiency of the three organic compounds was investigated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS).

Superiorities of BTH and BTAH corrosion inhibitors were shown by EIS data and polarization curves. Moreover, the results revealed that BTAH and BTH can function as effective mixed-type adsorptive inhibitors, whereas no inhibition behavior was observed for BI. Both BTAH and BTH obeyed Longmuir adsorption isotherm. The results obtained from this isotherm showed that both inhibitors adsorbed on the specimen surface physically and chemically. The difference in inhibition efficiencies of BTAH, BTH and BI was related to the presence of nitrogen and sulfur hetero atoms on their molecular structures.

This study evaluated inhibition efficiency of BI, BTAH and BTH using electrochemical methods. In addition, the study attempted to find inhibition mechanism of the inhibitors and to find modes of adsorption of the inhibitors, correlating effects of heteroatoms and inhibition efficiency.

The ideology of “Local Architecture” was about the religious experience, social and cultural interpretations non-awareness, and solutions for environmental and social problems. This case aims at producing a compatible architecture for this society. The problem of the paper deals with the absence of the local heritage in contemporary architecture. Most of our buildings reflect western ideologies, and use the local vocabulary, as has happened in most of the Arab architecture, that deals directly with a language of shapes to create compatibility with the public. Hence, the aim of the paper is to link the variables that the contemporary architecture formulated with concepts of local architecture. To meet such aims, the research is pivot around two themes: Firstly, tackling how to extract the forces that lead to the contemporariness of local heritage and formalize the DNA of any local community (Culture, Community Aspiration, Climate, and Technology), as well as discussing some experience that dealt with local architecture. Secondly, discussing some recent trials that learned from the previous attempts through history. The attempts strongly re-activate the local architecture in the contemporary challenges, namely, the use of heritage forms as is to conform to environmental determinants, development of these forms using contemporary materials through the visions of local architecture, and employing high-tech solutions to achieve contemporary appropriateness within traditional ideologies. In the end, the paper presents new ideas of the local architecture that learned from the previous experiences in our Arab societies to meet the needs of today's Arab societies.

The purpose of this paper is to prepare superabsorbent polymers (SAPs) based on acrylic acid, which is considered hygroscopic material to incorporate in rubber formulation, which results in producing moisten rubber that is used as roofing sheets.

SAPs were synthesized via free radical bulk polymerization technique using different content of cross-linker N, N'-methylenebisacrylamide and potassium persulfate. Differential scanning calorimeter, thermal gravimetric analysis, Fourier transform infrared spectroscopy and transmission electron microscopy were used to characterize SAPs and confirmed the formation of cross-linked hydrogel structure. The water absorbency and the gel fraction for sodium polyacrylate (NaPA) were investigated. Then, the influence of obtained NaPA on the swelling behavior of the prepared natural rubber (NR) compound has been discussed.

Absorption characteristics and gel fraction of NaPA were found to depend on the content of the cross-linker in the system. SAPs are used to improve the absorbance behavior and performance of the NR to produce, roofing sheets using in hot weather. The morphology of the obtained rubber compound was well-explained by using a scanning electron microscope.

The research provides a simple way to produce moisten rubber that can be used as a roofing sheet to overcome warm weather.

Moisten rubber roofing sheets provide a low-cost option in many developing countries with hot climates, and thus, help save the environment from global warming.

Into cultural and creative industries, the innovation is increasingly realized by a lead creator which is supported by a specific team. Hence, this paper aims to understand the composition of this particular team.

The authors conducted an in-depth case study of “Dal Pescatore”. This is the Italian restaurant keeping the highest award previewed by Michelin Guide from the longer period. The main figures of the restaurant are the head chefs (Nadia and Giovanni Santini) who are continually supported by a dedicated team

The analysis underlines the necessity to create a team which combines aged people linked to firms’ tradition with a low percentage of young foreign apprentices. If the old-timer member assures a deep understanding of the firm’s knowledge base, the young foreign apprentice can show an high learning attitude through which he/she more easily shares their different knowledge.

This study discussed organizational efforts to foster innovation capacities of the main individuals into a firm. However, the present research suffers from some limitations which limits the generalizability of the results beyond the company studied: a single case study on a small and family firm with consolidated organizational routines. In addition, this research does not solutions about the mechanisms of interaction among these different team members.

Recent studies observed how a number of cultural and creative firms innovate through a particular team that develops the ideas of a lead creator. Nevertheless, despite the increasing importance of these teams, their composition remains unclear.

Over the past few years, several scholars have focused on green innovation in the agri-food industry. In line with this research stream, the purpose of this paper is to cover some unexplored areas regarding if stakeholder pressures have a positive influence on family engagement to implement green innovation practices and socially responsible practices.

By adopting a qualitative research methodology, mainly based on a multiple case study, this paper seeks to cover some unexplored areas regarding the understanding the relationship between stakeholders, family involvement and business practices in green innovation. The authors analyze eight cases from five Latin American countries selected, all are family firms focused on agricultural production.

Latin American family firms from agri-food industry, have a positive influence from internal/external stakeholder to implement green innovation initiatives and socially responsible practices, that result in short/long term business practices.

The originality of the proposed conceptual model stems from the need to overcome the previous theoretical models based on the stakeholder theory, which deals separately with internal/external influence over the firm.

The purpose of this paper is to investigate the deposition of uniform, adherent and crack‐free Ni‐P thin films on carbon fibres using the electroless deposition technique.

Before applying the electroless process, the carbon fibre surfaces must be subjected to several treatment processes to remove the organic binder, etching and surface metallization. The surface morphology of the Ni‐P coatings was assessed using a scanning electron microscope (SEM). The chemical compositions of Ni‐P layers were identified by energy dispersive X‐ray analysis (EDS). The bond strength of the coated layer was determined by measuring the electrical resistance at the fibre/coating interface. The magnetic properties of the fibres were estimated using a hysteresis diagram. The tensile performance of single fibres coated by Ni‐P has been investigated with respect to coating thickness.

Pre‐treatment processes are used to improve the adhesion of Ni‐P layers and to obtain homogeneous coatings. The influence of plating parameters (temperature, pH and time) on the coating thickness of the Ni‐P layer was investigated. It was found that the coating thickness increased as the pH value, plating time and the temperature of the bath increased. The results revealed that a complete and uniform Ni‐P coating on fibre could be obtained at optimum conditions 85°C, pH 6, for 60 min, and the results indicated that the P content in the electroless deposit is approximately 3.4 wt%. The tensile strength values are improved significantly after coating and increased by 3‐5 times with increasing of coating thickness from 0.3 to 2 μm.

The results presented in this work are an insight into understanding of the deposition and adherence of Ni‐P thin films on carbon fibre using the electroless technique and behaviour of the coated fibre.

The purpose of this study is to examine mediating role of public sector governance in the relationship between entrepreneurship and economic growth in the Palestinian context during the years 2005–2020.

The necessary data were collected from the World Bank website and the annual financial reports of the Palestinian Monetary Authority. To achieve the study’s objectives, the researcher used content analysis method and regression model.

There is an effect of some dimensions of entrepreneurship (starting a business, obtaining credit, women starting a business) and public sector governance with dimensions (voice and accountability, political stability and absence of violence, effectiveness of government performance, organizational quality, the rule of law and control of corruption) on economic growth. In addition, there is no mediating effect of public sector governance in the relationship between entrepreneurship and economic growth.

The study helps in enhancing the elements of entrepreneurship by evaluating public governance in Palestine. It also offers future researchers a comprehensive vision that encourages Palestinian economic growth.

The paper contributes to showing the reality of public governance indicators for the Palestinian context and the amount of support for entrepreneurial activities indicators that affect economic growth.

Trying to activate cooperation mechanisms between government institutions and entrepreneurial institutions to adopt creative projects and ideas, especially for women, needs to focus on activating the principles of public sector governance in addition to facilitating administrative and financial procedures to start commercial projects in a way that enhances economic growth with the need to achieve the highest level of public sector governance indicators.

Core-shell is structured particles having several chemical compositions. The advantage of these particles arise from their specific design, to be used in decreasing costs by using inexpensive material (natural ore or waste material) as carrier for thin shell of active material. This study aims to prepare ferrites/silica core-shell pigments and compare their inhibition efficiency to original ferrites. These pigments have shells of different ferrites that comprise 10-15 per cent of the prepared pigments on silica fume. Silica fume which is the core is a byproduct in the ferro–silicon industry; this core comprises 85-90 per cent of the prepared pigments.

The prepared core-shell pigments were characterized using transmission electron microscopy analysis, energy-dispersive X-ray analysis and sequential wavelength dispersive X-ray fluorescence. These pigments were integrated in epoxy-based paint formulations, and the physical, mechanical and corrosion properties of dry films were examined. The corrosion properties were studied by using immersion test in 3.5 per cent NaCl for 28 days.

This study showed that these new eco-friendly and inexpensive pigments are similar to ferrites in their inhibition performance, i.e. they exhibited high corrosion prevention.

Domestic waste materials were reused in paints and only simple modification was used, and then, their effectiveness showed similar performance to that of the original pigments.

Ferrite and ferrite/silica pigments are environmentally friendly pigments that can replace other hazardous pigments (e.g. chromates) with almost the same quality in their performance; also, they can be used in industries other than paints (e.g. paper, rubber and plastics composites).
