Agent-based simulation in a normative environment using the EPMP domain.

Simulation is a way of doing thought experiments besides the deduction and induction methods. Agent-based Simulation (ABS) falls under the domain of artificial intelligence when agent is used to perform certain tasks such as behaviour prediction, optimization of functions or time-constrained work-flow management. This work discussed the use of ABS on a computational normative framework based on a set of empirical characteristics that influence agents’ performance in time-constrained environment. The ABS simulates a domain called the Examination Preparation and Moderation Process (EPMP) which entails document submission processes with deadlines. The simulation is conducted in six different environments and the results of the agent performance in each environment are presented and discussed. The results indicate that the simulation conducted in the EPMP is suitable and effective for evaluating normative agent-based systems

A spill over effect of entrepreneurial orientation on technological innovativeness:an outlook of universities and research based spin offs

partially_open5siBy shifting towards Romer’s (Am Econ Rev 94:1002–1037, 1986) economy and so the spread of knowledge economy, universities started to adopt a collaborative approach with their entrepreneurial ecosystem. They turn out to be risk taker, autonomous, proactive, competitive, and innovative. In a nutshell, they are entrepreneurial oriented with the aim to generate new innovative ventures, known as research-based spin offs. Doubly, this has induced an improvement of technology transfer and the degree of entrepreneurship in the current knowledge economy. However there still is a paucity of studies on the spill over effect of entrepreneurial orientated universities and research-based spin off on technology transfer need to be more explored. Therefore, the article investigates the link between entrepreneurial orientation and such spill overs by offering an outlook of two universities and two research-based spin offs in the United Kingdom. The scope is to provide a deep view of technological innovativeness in a research context, entrepreneurial oriented. Our research suggests that entrepreneurial attitude has become an imperative to succeed in the context where British institutions currently operate. Entrepreneurship brings the necessary technological innovation to the university and its students, which results in better positioning of the university at national and international levels, with the subsequent impact on their ability to attract not only new students and academics but also funding to conduct their research.openScuotto, Veronica; Del Giudice, Manlio; Garcia-Perez, Alexeis; Orlando, Beatrice; Ciampi, FrancescoScuotto, Veronica; Del Giudice, Manlio; Garcia-Perez, Alexeis; Orlando, Beatrice; Ciampi, Francesc

Effects of even and odd number fatty acids cofeeding on PHA production and composition inPseudomonas putidaBet001 isolated from palm oil mill effluent

The biosynthesis of medium-chain-length poly-3-hydroxyalkanoates by Pseudomonas putida Bet001 cultivated on mixed carbon sources was investigated. The mixed carbon sources consisted of heptanoic acid (HA) and oleic acid (OA). A relatively low PHA content at 1.2% (w/w) and 11.4% (w/w) was obtained when HA or OA was used as the sole carbon source. When these fatty acids were supplied as a mixture, PHA content increased threefold. Interestingly, the mixture-derived PHA composed of both odd and even monomer units, namely. 3-hydroxyheptanoate, 3-hydroxyoctanoate, 3-hydroxydecanoate, and 3-hydroxydodecanoate and no unsaturated monomer was detected. It is hypothesized that the even-numbered monomers were derived primarily from OA, whereas the odd-numbered monomer was derived from HA. This also points out to an efficient and yet distinct fatty acids metabolism that fed the PHA biosynthesis machinery of this particular microorganism. PHA obtained was elastomeric because melting temperature (Tm) and crystallinity were absent. It showed good thermal stability with degradation temperature (Td) ranging from 275.96 to 283.05 °C

Green Revolution's Role and Impact: Organic Farming Potential for Indonesian Sustainable Agriculture

Pada 1960-an, Indonesia mengalami kekurangan beras dan termasuk salah satu pengimpor beras terbesar di dunia. Pemerintah saat itu memprioritaskan pemenuhan beras dengan target swasembada dengan berbagai upaya, seperti penerapan teknologi revolusi hijau (RH) melalui penggunaan input pertanian modern. RH terbukti membuat Indonesia mencapai swasembada beras pada tahun 1984. Namun, teknologi tersebut juga telah menyebabkan dampak negatif, terutama kerusakan lingkungan dan petani sangat bergantung pada industri agro- kimia. Beberapa kalangan menganggap sistem pertanian organik adalah solusi untuk mengatasi masalah ini. Pertanian organik menawarkan cara terbaik untuk produksi pangan dan penggunaan sumber daya secara berkelanjutan dan ramah lingkungan. Permintaan beras organik diperkirakan akan meningkat di masa mendatang seiring dengan pertumbuhan penduduk dan pendapatan. Adopsi pertanian organik masih sangat lambat. Tantangan utama pertanian padi organik adalah kekhawatiran anjloknya hasil panen ketika melakukan konversi. Permasalahan lainnya adalah kurangnya pengetahuan teknis dan dukungan pemerintah, mahalnya biaya konversi dan kontaminasi bahan kimia dari pertanian konvensional. Diperlukan penelitian yang lebih mendalam tentang faktor-faktor yang memengaruhi petani untuk mengadopsi pertanian organik. Dengan demikian pemerintah dapat merancang strategi dan kebijakan yang tepat untuk mempercepat adopsi pertanian padi organik

Lipase-catalyzed synthesis of 6-o-d-glucosyldecanoate in tert-butanol: reaction optimization and effect of mixing power input

Enzymatic synthesis of 6-O-D-glucosyldecanoate in tert-butanol was performed using substrates D-glucose as acyl acceptor and decanoic acid as acyl donor. Candida antarctica lipase B (Novozyme 435) was used as the catalyst in the esterification process. Box Behnken of response surface methodology (RSM) was used in the optimization of selected parameters viz. reaction temperature, reaction time, substrate ratio and amount of enzyme loading. Substrate ratio was found to be the sole significant main effect while the second-order interaction between reaction time and immobilized enzyme loading was found to be a significant interaction factor. Optimized conditions for the process were: substrate molar ratio 1 (mole acyl donor-to-mole acyl acceptor), 7.5 g·L-1 immobilized enzyme loading, reaction temperature 55°C and time of 14.2 hours. When a mixed-flow impeller with downward pumping mode was used in a stirred tank reactor, minimum power input at 6.8 kW·kg-1 solvent was sufficient for an improved yield of 0.77 g glucosyl decanoate per g glucose. The reaction product composed solely of monoester with sugar acylation occurring at 6-OH primary group of D-glucose where 60 (mole) of the product was 6-O-β-D-glucosyldecanoate and 40 (mole) 6-O-α-D-glucosyldecanoate
