Biomass-Derived Carbonaceous Materials: Recent Progress in Synthetic Approaches, Advantages, and Applications

Abstract: Current energy shortages and environmental crises have compelled researchers to look for inexpensive and sustainable resources that can be obtained via environmentally friendly routes to produce novel functional materials. Biomass has been identified as one of the promising candidates given its availability in large quantities and renewable nature. Among the various feasible synthetic strategies, hydrothermal carbonization (HTC) has been admired for its energy efficiency and ability to synthesize carbonaceous materials for use in a wide range of applications. In this review, the different types of biomass and strategies available for the synthesis of carbon-based materials are discussed. Furthermore, factors influencing the efficiency of each strategy are analyzed and evaluated. Subsequently, the utilization of carbonaceous materials in environmental, catalytic, electrical, and biological applications are reviewed to further demonstrate their functionalities across different fields.

Contemporary practice and technical aspects in coronary intervention with bioresorbable scaffolds: A European perspective

Abstract: Aims Next to patient characteristics, the lack of a standardised approach for bioresorbable vascular scaffold (BVS) implantation is perceived as a potential explanation for the heterogeneous results reported so far To provide some guidance, we sought to find a consensus on the best practices for BVS implantation and management across a broad array of patient and lesion scenarios Methods and results Fourteen European centres with a high volume of BVS procedures combined their efforts in an informal collaboration To get the most objective snapshot of different practices among the participating centres, a survey with 45 multiple choice questions was prepared and conducted The results of the survey represented a basis for the technical advice provided in the document, whereas areas of controversy are highlighted Conclusions Consensus criteria for patient and lesion selection, BVS implantation and optimisation, use of intravascular imaging guidance, approach to multiple patient and lesion scenarios, and management of complications, were identified

Characterization of the inhibitory roles of RFRP3, the mammalian ortholog of GnIH, in the control of gonadotropin secretion in the rat: in vivo and in vitro studies

Abstract: RF-amide related peptides (RFRP), as putative mammalian orthologs of the avian gonadotropin-inhibitory hormone (GnIH), have been proposed as key regulators of gonadotropin secretion in higher vertebrates. Yet considerable debate has arisen recently on their physiological relevance and potential mechanisms and sites of action. Present studies were undertaken to further characterize the effects of RFRP on LH and FSH secretion by a combination of in vivo and in vitro approaches in male and female rats. Initial screening via intracerebroventricular (icv) administration of different analogs of RFRP1 (RFRP1-12 and RFRP1-20) and RFRP3 (RFRP3-8 and RFRP3-17), as well as the related neuropeptide FF (NPFF8), to gonadectomized (GNX) female rats evidenced significant, albeit modest, inhibitory effects on LH secretion only for RFRP3-8 and RFRP3-17, which were detectable at the high dose rage (1 nmol for RFRP3-8, 5 nmol for RFRP3-17). This moderate inhibitory action was also documented after icv administration of RFRP3-8 to intact and GNX male rats. In addition, systemic (intravenous) administration of RFRP3-8 decreased the circulating levels of both gonadotropins in GNX male rats. Likewise, RFRP3-8 inhibited basal and GnRH-stimulated LH secretion by pituitaries from GNX males in vitro. This inhibitory effect was blocked by the antagonist of RFRP receptors, RF9. In summary, our results support a putative inhibitory role of RFRP3 as ortholog of GnIH in the regulation of gonadotropin secretion in mammals, which appears to involve direct pituitary actions as well as potential central (hypothalamic) effects.

A survey on educational process mining

Abstract: Educational process mining (EPM) is an emerging field in educational data mining (EDM) aiming to make unexpressed knowledge explicit and to facilitate better understanding of the educational process EPM uses log data gathered specifically from educational environments in order to discover, analyze, and provide a visual representation of the complete educational process This paper introduces EPM and elaborates on some of the potential of this technology in the educational domain It also describes some other relevant, related areas such as intentional mining, sequential pattern mining and graph mining It highlights the components of an EPM framework and it describes the different challenges when handling event logs and other generic issues It describes the data, tools, techniques and models used in EPM In addition, the main work in this area is described and grouped by educational application domains
