TL;DR: In this paper, a survey was conducted to undergraduate students in Portugal, UAE and Ukraine to investigate learners' perceptions, attitudes and willingness to try distance education courses and programs to provide guidance and recommendations for IHEs that are considering expanding use of DE formats.
Abstract: Many universities offer Distance Education (DE) courses and programs to address the diverse educational needs of students and to stay current with advancing technology. Some Institutions of Higher Education (IHE) that do not offer DE find it difficult to navigate through the steps that are needed to provide such courses and programs. Investigating learners’ perceptions, attitudes and willingness to try DE can provide guidance and recommendations for IHEs that are considering expanding use of DE formats. A survey was distributed to undergraduate students in Portugal, UAE and Ukraine. The results of this pilot study showed that in all three countries, students’ major concerns about such programs were time management, motivation, and English language skills. Although students were somewhat apprehensive many indicated they were interested in taking DE courses. Six recommendations informed by interpretation of students’ responses and the literature, are offered to assist institutions who want to offer DE as part of their educational strategy.

TL;DR: This review intends to compile and describe the most used approaches for enzyme stabilization highlighting case studies in a practical point of view.
Abstract: Enzymes are efficient catalysts designed by nature to work in physiological environments of living systems. The best operational conditions to access and convert substrates at the industrial level are different from nature and normally extreme. Strategies to isolate enzymes from extremophiles can redefine new operational conditions, however not always solving all industrial requirements. The stability of enzymes is therefore a key issue on the implementation of the catalysts in industrial processes which require the use of extreme environments that can undergo enzyme instability. Strategies for enzyme stabilization have been exhaustively reviewed, however they lack a practical approach. This review intends to compile and describe the most used approaches for enzyme stabilization highlighting case studies in a practical point of view.

TL;DR: In this article, a biphasic scaffold was built by attaching a fused deposition modelled bone compartment to a melt electrospun periodontal compartment, and the bone compartment was coated with a calcium phosphate layer for increasing osteoconductivity, seeded with osteoblasts and cultured in vitro for 6 weeks.
Abstract: AIM:
This study investigated the ability of an osteoconductive biphasic scaffold to simultaneously regenerate alveolar bone, periodontal ligament and cementum.
MATERIALS AND METHODS:
A biphasic scaffold was built by attaching a fused deposition modelled bone compartment to a melt electrospun periodontal compartment. The bone compartment was coated with a calcium phosphate (CaP) layer for increasing osteoconductivity, seeded with osteoblasts and cultured in vitro for 6 weeks. The resulting constructs were then complemented with the placement of PDL cell sheets on the periodontal compartment, attached to a dentin block and subcutaneously implanted into athymic rats for 8 weeks. Scanning electron microscopy, X-ray diffraction, alkaline phosphatase and DNA content quantification, confocal laser microscopy, micro computerized tomography and histological analysis were employed to evaluate the scaffold's performance.
RESULTS:
The in vitro study showed that alkaline phosphatase activity was significantly increased in the CaP-coated samples and they also displayed enhanced mineralization. In the in vivo study, significantly more bone formation was observed in the coated scaffolds. Histological analysis revealed that the large pore size of the periodontal compartment permitted vascularization of the cell sheets, and periodontal attachment was achieved at the dentin interface.
CONCLUSIONS:
This work demonstrates that the combination of cell sheet technology together with an osteoconductive biphasic scaffold could be utilized to address the limitations of current periodontal regeneration techniques.

TL;DR: In this article, the authors analyse the growing body of literature on small and medium-sized enterprise (SME) internationalisation by considering a set of propositions regarding the drivers and inhibitors of an entry mode decision.
Abstract: Purpose – This paper aims to analyse the growing body of literature on small and medium‐sized enterprise (SME) internationalisation by considering a set of propositions regarding the drivers and inhibitors of an entry mode decision.Design/methodology/approach – Following a quantitative methodological approach, a survey was applied to a sample of SMEs to empirically test the proposed conceptual model. Logistic regression analysis was used to analyse the data.Findings – Results from the study revealed the importance of the firm's international experience, its ability to innovate, the market potential for growth and market‐specific knowledge as key predictors for choosing an equity‐entry mode. SMEs are rather flexible in nature and tend to perform activities with low‐cost structures, thereby minimising the relevance of the perceived risk associated with the host country.Practical implications – Empirical findings are relevant as they may assist SME managers to make financially sound entry mode choices, which...
