| Paper ID | zT0YO |
| Keywords | honey; physicochemical parameters; microelements; macroelements; heavy metals; amino acids; bioactivity; antimicrobial; antibacterial; antifungal |
| Abstract |
Read more…Six samples of Moldavian honey from different regions were analyzed, physical and chemical parameters, the content of macro-, microelements, and aminoacids were determined, as well as antibacterial and antifungal activity. The antibacterial and antifungal properties were determined using the double serial dilution method. It was established that all of the samples of acacia, linden, and sunflower honey possess high antibacterial activity. The bioactivity of the samples of honey was proven to be dependent on the type and origin of honey. Sunflower honey has higher antibacterial potency than linden, but linden honey is more active than acacia. Both Gram-positive and Gram-negative bacterial species proved to be susceptible to Moldavian honey. Acacia, linden, and sunflower honey, possess high antibacterial potency against S. aureus and P. aeruginosa even at a dilution of 1:16 (2.5%). The studied samples showed weak antifungal activity against Candida albicans, with the MIC determined at 1:2 dilution (20%). For linden and sunflower honey, the antifungal activity was higher than for acacia honey. The samples with the best bioactivity (sunflower honey) contain a higher amount of free acids, had lower pH values of the honey solution, and these samples also have the highest content of OMF. |

| Paper ID | BlWXM |
| Keywords | Digitalization of technological innovation; Digital technologyproximity; Digital transformation performance; Digital innovation ability; Social network |
| Abstract |
Read more…In the new wave of technological revolution, information technology is currently the most innovative areas around the world. Technological innovation isincreasingly focused on digitalization. However, little research has attempted to investigate method to measure the digitalization of technological innovation and its impact. Based on longitudinal multiple data sources, including comprising patent documents, annual reports of listed Chinese manufacturing firms, a third-party database. We introduce a novel construct, namely digital technology proximity, to capture how firms digitize their technological innovation based on social network. Meanwhile, we consider firms� digital transformation performance, measured by the proportion of digital-related revenue, as the impact of digitalization of technological innovation. Our unbalanced-panel regression and robustness tests reveal a positive link between digitalization of technological innovation and firms� digital transformation performance, supporting the notion that technologicalinnovation digitalization empowers firms� digital transformation. In addition, digital innovation ability exerts a significant mediating effect for digitalization of technological innovation. This research introduces a new method of measuring the digitalization of technological innovation and its impact on digital transformation. |

| Paper ID | rgSzG |
| Keywords | educational system, entrepreneurial university, innovative education, curriculum goals, competences |
| Abstract |
Read more…There is a challenge to the experts and those in charge with the education and training to create an education system that is continuously adjusting to a changing society, able to facilitate and support transformations that occur in the business environment and beyond, and to determine the economic growth both at the local, regional, national and international level as well as at the level of organizations, groups, and individuals.\nCountries that have nowadays recorded significant economic growth have an education system based on an entrepreneurial culture, the most relevant examples being Finland, Norway, New Zealand, USA, Canada and Japan. These countries have managed to redefine their strategy starting with the primary education system and creating a complex network of institutions that are developing entrepreneurial skills and abilities, focusing on an educational curriculum tailored for the business environment.\nThe educational reform in these countries has led to the educational decentralization, building educational networks for the know-how transfer between regions, developing collaborative projects between universities, public institutions and business organizations, on-going training programs and lifelong learning, entrepreneurship and collaborative business culture.\nThis paper aims to propose a model for an entrepreneurial university that can represent a challenge for the higher education system in Romania, where the educational reform can lead to educational decentralization, building educational networks for the transfer of know-how between regions, developing collaborative projects between the universities, public institutions and business organizations, on-going training programs and lifelong learning, entrepreneurship and a collaborative business culture. |

| Title | VLSI Implementation of Impulse Noise Reduction based on Optimal Detection Algorithm |
| Paper ID | XkaBT |
| Keywords | Impulse noise reduction, Power consumption, Edges, Image quality, Optimal detector. |
| Abstract |
Read more…Images are often corrupted by impulse noise during the process of image acquisition and transmission. In this research, optimal detector noise filtering algorithm is proposed which detects and removes the impulse noise from the noise affected images, especially while compared with other state of arts in terms of image quality and mean square error. The process of impulse noise detection includes finding of the optimum direction, through the estimation of standard deviation in various directions of the filtering window. It also preserves the edges in the images during the denoising process. The efficient hardware architecture for optimal detector noise filtering is presented in this research. The design possesses only two line memory buffers with very low computational complexity, thereby reducing the hardware cost and appropriate for several real-time applications. The proposed hardware architecture consumes 1728gates and power consumption of 203.27mW. |

| Title | ESGC: Euclid’s Theorem Based Key Generation Algorithm for Secure Intra-Group Communication in MANETs |
| Paper ID | kq4jl |
| Keywords | Euclid’s Theorem, Intra-Group Communication, Mobile Adhoc Networks, Forward and Backward Secrecy. |
| Abstract |
Read more…Many emergency communications is based on mobile Adhoc networks. It suffers from restricted communication and hardware capabilities of mobile nodes. Dynamic key management is an important factor for all security goals in MANETs. In this paper we propose a scheme to generate the public and private keys through Euclid’s theorem. The forward and backward secrecy in creating the group key is done through Breadth First Search (BFS) and Depth First Search (DFS) traversals respectively. The group key evolved during this process ensures secured data transfer among the group nodes by encryption/decryption using group key. The proposed scheme enhances the computational complexity of the group key generation algorithm to provide effective and secure communication among the group nodes. The proposed scheme was simulated in NS2 to analyze the computational and communicational capabilities in group key management. This scheme proves more secured than other key management protocols in mobile Adhoc networks. |

| Title | Effects of Simvastatin on cerebral ischemic injury, resulted from Hyperthermia |
| Paper ID | yKI8Q |
| Keywords | Simvastatin, cerebral ischemic injury, hyperthermia, stroke, rat |
| Abstract |
Read more…Stroke and its consequences like ischemic injury can be induced by some mechanisms, which damage body tissues. Finally, the problem can lead to some spinal neural disorders like Cerebral Palsy (CP) or death. Some pathological processes would lead to increase in body temperature and hence, body temperature would exceed the maximum capacity of hypothalamus to regulate body temperature. As a result, the process would lead to hyperthermia. Hyperthermia would be increased in patients in early days after stroke, induced by ischemic injury from 4.5 to 60.8%. The main objective of the present study is to investigate effects of Simvastatin on ischemic injury of brain, resulted from hyperthermia through thromboembolic model of stroke on rats. Hypothermia would hide useful effects of some neuroprotective factors such as tissue activator of plasminogen as a useful treatment in theromboembolic stroke. Another neuroprotective factor (MK-801), as non-competitive antagonist of NMDA receivers, would be disappeared by hyperthermia. Neuroprotective treatment refers to a treatment, in which neural system and especially neurons would be protected against cerebral ischemia and as a result, neuron death and neurologic disorders and even death would be decreased. In relevant researches, statins would be considered as neuroprotective factors and neural neurorestorative factors in cerebral stroke, induced by brain ischemic injury. |
