Late antiquity after antiquity: the last of the ancient platonists in the early modern period

LAAA will provide the first systematic study of the rich – yet understudied – interpretative legacy of late antiquity in the history of Western philosophy, with a focus on Platonism. It will show that in the early modern period the most influential portraits of the ancient philosophical past were inspired and shaped by representations of this past produced in late antiquity. 
In its attempt to explore the philosophical heritage of these representations, LAAA will begin in the investigation of the hermeneutical approach of the humanist philosopher Marsilio Ficino (1433-1499), who produced the first Latin translation of the entire Platonic corpus by using the newly discovered texts of the late antique Platonists as interpretative tools.
This approach created a form of Platonism deeply imbued with the theurgically oriented tradition of late antiquity. LAAA’s goals are to disentangle the different interpretative threads which run under the label ‘early modern Platonism’ and to examine its impact in different fields of early modern European knowledge, as well as its role in the shaping of our intellectual and cultural identity. By retracing the complex narrative of filiation which characterizes the reception history of Platonism, LAAA will reassess the role of late antiquity not in its own time, but from the general viewpoint of the historical development of Western thought. This is a totally new perspective in the study of late antiquity, which will be examined as a dynamic territory for the preservation, transformation and transmission of classical texts, as well as a longstanding source of authority and inspiration.
Effect of land use and land cover change on ecosystem services in Naidong County on the Tibetan Plateau, China

Land use and land cover change (LUCC) on a regional scale is one of the major research topics in global climate change studies. In recent years, an increasing number of researchers have highlighted the significance of case studies in understanding LUCC patterns and processes. The Tibetan Plateau ecosystem is a typical fragile ecosystem that is extremely difficult to restore once it is damaged. Thus, studies on LUCC and its effects on the environment have great theoretical and practical significance. In this study, LUCC and changes in ecosystem services in Naidong County on the Tibetan Plateau, China between 1988 and 2000 are investigated. LANDSAT Thematic Mapper (TM) of 1998 and Enhanced Thematic Mapper Plus (ETM+) images of 2000 are used to detect LUCC, and then changes in the values of ecosystem services delivered by each land category are investigated. Finally, the contribution of various ecosystem functions to the overall value of ecosystem services is discussed. The results show that the enhancement of forest areas is the most prominent characteristic of change in land use, specifically the conversion from 659.23 ha of wetlands, 501.51 ha of grasslands, and 163.07 ha of desert to forests from 1988 to 2000 in study area. The total value of ecosystem services in Naidong County declined from ¥1655.16 million to ¥1640.21 million between 1988 and 2000. This decrease can be largely attributed to the loss of wetlands (valued at ¥36.58 million), whereas the ecosystem services value of forests increased by ¥25.60 million during that period. The sensitivity analysis revealed that the contributions of gas regulation, soil formation and erosion control, biological diversity, and raw materials to the total value of ecosystem services increased over the 12-year period. Moreover, the contributions of waste treatment, water conservation, climate regulation, recreation and culture, and food production significantly decreased during the same period.

Turbulence intensity measurement in the wind tunnel used for airfoil flutter investigation

The paper reports on hot wire turbulence intensity measurements performed in the entry of a suction-type wind tunnel, used for investigation of flow-induced vibration of airfoils and slender structures. The airfoil is elastically supported with two degrees of freedom (pitch and plunge) in the test section of the wind tunnel with lateral optical access for interferometric measurements, and free to oscillate. The turbulence intensity was measured for velocities up to M = 0.3 i) with the airfoil blocked, ii) with the airfoil self-oscillating. Measurements were performed for a free inlet and further with two different turbulence grids generating increased turbulence intensity levels. For the free inlet and static airfoil, the turbulence intensity lies below 0.4%. The turbulence grids G1 and G2 increase the turbulence level up to 1.8% and 2.6%, respectively. When the airfoil is free to oscillate due to fluid-structure interaction, its motion disturbs the surrounding flow field and increases the measured turbulence intensity levels up to 5%.
Catalytic gasification of automotive shredder residues with hydrogen generation

Abstract Hydrogen is a clean and new energy carrier to generate power through the Proton exchange membrane fuel cell (PEMFC) system. Hydrogen can be effectively turned out through the catalytic gasification of organic material such as automotive shredder residues (ASR). The main objective of this manuscript is to present an analysis of the catalytic gasification of ASR for the generation of high-purity hydrogen in a lab-scale fixed-bed downdraft gasifier using 15 wt.% NiO/Al2O3 catalysts at 760–900 K. In the catalytic gasification process, reduction of Ni(II) catalyst into Ni(0) has been confirmed through XANES spectra and consequently EXAFS data shows that the central Ni atoms have Ni–O and Ni–Ni bonds with bond distances of 2.03 ± 0.05 and 2.46 ± 0.05 A, respectively. ASR is partially oxidized and ultimately converts into hydrogen rich syngas (CO and H2) and increases of the reaction temperature are favored the generation of hydrogen with decomposition of the CO. As well, approximately 220 kg h−1 of ASR would be catalytically gasified at 760–900 K and 46.2 atm with the reactor volume 0.27 m3 to obtain approximately 3.42 × 105 kcal h−1 of thermal energy during over 87% syngas generation with the generation of 100 kW electric powers.
Calculation of porosity from nuclear magnetic resonance and conventional logs in gas-bearing reservoirs

The porosity may be overestimated or underestimated when calculated from conventional logs and also underestimated when derived from nuclear magnetic resonance (NMR) logs due to the effect of the lower hydrogen index of natural gas in gas-bearing sandstones. Proceeding from the basic principle of NMR log and the results obtained from a physical rock volume model constructed on the basis of interval transit time logs, a technique of calculating porosity by combining the NMR log with the conventional interval transit time log is proposed. For wells with the NMR log acquired from the MRIL-C tool, this technique is reliable for evaluating the effect of natural gas and obtaining accurate porosity in any borehole. In wells with NMR log acquired from the CMR-Plus tool and with collapsed borehole, the NMR porosity should be first corrected by using the deep lateral resistivity log. Two field examples of tight gas sandstones in the Xujiahe Formation, central Sichuan basin, Southwest China, illustrate that the porosity calculated by using this technique matches the core analyzed results very well. Another field example of conventional gas-bearing reservoir in the Ziniquanzi Formation, southern Junggar basin, Northwest China, verifies that this technique is usable not only in tight gas sandstones, but also in any gas-bearing reservoirs.
Detailed Design of a 2,000 A, 400 mH Toroid-Type HTS DC Reactor for an HVDC System

General DC reactors in high-voltage direct current systems experience an electrical loss due to the resistance from copper winding in the DC reactor. The toroid-type high-temperature superconducting (HTS) DC reactor can be expected to decrease the disadvantages associated with general DC reactors. In this paper, the design of a toroid-type HTS DC reactor is presented. The magnetic fields of the toroid-type HTS DC reactor magnet were analyzed using the finite element method program. The conduction cooling system of the HTS DC reactor was designed based on the results of thermal analysis. The target current and inductance of the HTS DC reactor were 2,000 A and 400 mH, respectively at 20 K.
Welfare Facilities for better Industrial Relations – An empirical study of Indian Jute Industry in Post Liberalisation

Provision of welfare amenities enables the workers to live a richer and more quality life and thereby contributes to their efficiency and productivity. It helps to maintain industrial peace. Increased productivity of an industrial undertaking, indisputably, results from mental happiness of  employees.Mental happiness of an employee in turn is a function of welfare facilities provided by the employer. Welfare facilities make the life of the employee comfortable and happy. The labour welfare covers a broad field and connotes a state of well-being, happiness, satisfaction, conservation and development of human resources. The Jute Industry, which is one of the oldest traditional industry providing employment opportunities to huge number of population particularly unskilled and semiskilled. Earlier studies revealed that there were lot of strikes and lockouts taken place in Jute Industry. This is one of the traditional industries which lost huge number of manly hours, loss of productivity due to poor industrial relations. So, the researcher studied the impact of liberalization on industrial relations in Jute Industry in post liberalization particularly relating to implementation of Welfare facilities in North Coastal Andhra Pradesh. The author collected the opinions from the sample respondents through a structured questionnaire and analyzed the same with the help of five point Likert scale and weighted average method. It reveals that in post liberalization employers implement the statutory and some of the non-statutory facilities like restrooms, lunchrooms, hygienic canteen facility, first-aid boxes, ambulance facility, etc. which lead to the more employee welfare.
Camera-Vision Based Oil Content Prediction for Oil Palm (Elaeis Guineensis Jacq) Fresh Fruits Bunch at Various Recording Distances

In this study, the correlation between oil palm fresh fruits bunch (FFB) appearance and its oil content (OC) was explored. FFB samples were recorded from various distance (2, 7, and 10 m) with different lighting spectrums and configurations (Ultraviolet: 280-380nm, Visible: 400-700nm, and Infrared: 720-1100nm) and intensities (600watt and 1000watt lamps) to explore the correlations. The recorded FFB images were segmented and its color features were subsequently extracted to be used as input variables for modeling the OC of the FFB. In this study, four developed models were selected to perform oil content prediction (OCP) for intact FFBs. These models were selected based on their validity and accuracy upon performing the OCP. Models were developed using Multi-Linear-Perceptron-Artificial-Neural-Network (MLP-ANN) methods, employing 10 hidden layers and 15 images features as input variables. Statistical engineering software was used to create the models. Although the number of FFB samples in this study was limited, four models were successfully developed to predict intact FFB’s OC, based on its images’ color features. Three OCP models developed for image recording from 10 m under UV, Vis2, and IR2 lighting configurations. Another model was successfully developed for short range imaging (2m) under IR2 light. The coefficient of correlation for each model when validated was 0.816, 0.902, 0.919, and 0.886, respectively. For bias and error, these selected models obtained root-mean-square error (RMSE) of 1.803, 0.753, 0.607, and 1.104, respectively.

Could senescence be adaptive? causes and consequences of aging across the tree of life

Why do organisms age? This is surely one of the most compelling questions in biology. With advancing age, organisms can see physiological decline leading to higher mortality and lower fertility, a process known as ‘senescence’. The foundations of aging research state senescence should be inevitable in any organism, and is likely a by-product of attenuation in force of selection with age. But is senescence inevitable? Could senescence be adaptive?

Senescence is not inevitable, according to recent research from the Max Planck Odense Center, University of Southern Denmark. Species’ aging trajectories are diverse; mortality and fertility may increase, decrease or stay constant with age. We need a new way to understand aging, which recognises this diversity and seeks to understand pattern and process in the evolution of aging across the tree of life. The WHYAGE project explores ecological consequences and evolutionary causes of diversity in aging from this ‘macro’ perspective.

Senescence could be adaptive. This proposal presents a theoretical framework under which certain environmental disturbances affecting population age structures could, through population-level processes, favour senescent individuals. More generally, diverse environmental disturbance regimes could help explain diversity of aging across the tree of life.

Three objectives facilitate the project. First, demographic method development will allow better understanding of aging trajectories in mortality and fecundity, and population dynamics influenced by these. Second, comparative phylogenetic analyses of global demographic databases of plants and animals will uncover the consequences of aging for population dynamics across the tree of life. This knowledge will inform the third objective; development of theoretical population models exploring how environmental disturbances and population dynamics feed into evolutionary processes, and using these to find conditions under which senescence may be adaptive.
Multi-Camera autonomous robotic set for the ultimate and cost-effective live video

Inconsistent quality, high personnel costs and personnel admin overheads are the main bottlenecks faced by video production companies. Small-medium ones besides, must handle with very tight budgets, offering the bare minimum as result (limited camera angles and repetitive movements) and risking zero profits in case of production overruns. Automation (artificial intelligence and robotics that replace repetitive and routine tasks) has emerged as an innovative solution to execute production tasks more efficiently and allow companies to remove economic bottlenecks and devote more resources to creative activities. However state-of-the-art automation technologies are limited to assistive systems or partial automation based on pre-established scripts (cameras' movement, framing time and broadcast sequence), so they are not suitable for live shows such as sports events or concerts.
Seervision, the only player offering an affordable full automation solution, will revolutionize the video production industry through Multi RoboDoP: an easy-to-use platform that autonomously controls multiple cameras, tracks objects smoothly and takes smart decisions to perform all operational tasks of traditional crews at a superior quality. Multi RoboDoP will disrupt the cost structure of today’s video productions by halving their production costs. Moreover, we will unlock 50% of the market that cannot afford professional video productions (mid-sized video production companies and small studios) while we increase ROI for large-scale companies.
So far, we have invested more than €1M to reach TRL7 and we envisage €2.19M and 1.5 years to finish developing our proprietary multi-camera coordination software, prepare its scale-up and its market launch.
We have identified 12 priority target countries representing a SAM of >€700M. After launch to market in Q4 2021, we estimate 2.5 years to reach break-even, 4 years to get a 3-4% overall market share, €27.8M in revenues and a ROI of 6.67.
The Penumbra Coil 400 System for Treatment of Wide-Necked Intracranial Aneurysms: Initial Single-Center Experience

Endovascular treatment of wide-necked intracranial aneurysms frequently requires stent- or balloon-assisted coiling to prevent coil herniation into the parent artery. Provided that coils can be securely deployed within the aneurysm sac, these adjunctive devices and their associated risk can be avoided. The Penumbra 400 Coil (PC-400) has a larger diameter than conventional coils and is constructed completely of metal, a feature that increases the coil stability and may improve its ability to respect the aneurysm neck. The purpose of this study was to examine the frequency of adjunctive stent usage when coiling wide-necked intracranial aneurysms with the PC-400 in comparison with conventional coils. We examined consecutive patients with unruptured wide-necked aneurysms treated at our institution with endovascular coils. Aneurysm characteristics and procedural outcomes were compared between patients treated with PC-400 compared with a control group treated with conventional coils. Thirty-eight patients met criteria for this study. Stent-assisted coiling was required in 34 % fewer cases using PC-400 compared with conventional coils (P = .049). Fewer coils and less length were required with the PC-400 to obtain the same packing densities, occlusion types, and short-term stability. This may reduce treatment cost and prove to be valuable in patients with contraindications to dual antiplatelet therapy.KeywordsIntracranial aneurysmEmbolizationPenumbra Coil 400Stent-assisted coilingWide necked
Research on Smoke Control by Combination of Corridor Smoke Outlet and Smoke Retaining Screen in High-rise Buildings

The corridor of high-rise building is the important approach to dissipate smoke in the fire,and also the only way for personnel evacuation.In this paper,through establishing the mathematical model of smoke movement in the high-rise building,the k-e equation 3-D turbulent model were adopted,and FLUENT software was utilized to simulate the mechanical smoke discharge in different smoke discharge modes in the fire of high-rise buildings,the distance between different smoke outlets in the straight corridor and smoke retaining screen was compared and analyzed,as well as the smoke dissipation conditions in the corridor with the smoke retaining screen in different heights.The results illustrated that the smoke retaining screen set in the straight corridor could well reduce the hazard of the downstream corridor of the smoke retaining screen.Furthermore,the distance between the smoke retaining screen and smoke outlet had small influence on the smoke discharge,and the drooping height of the smoke retaining screen was the key factor to affect the smoke discharge effect.In addition,whenever the drooping height of the ceiling screen was increased by 0.2 m,the average downstream temperature would be reduced by 10 ℃.
Synthetic Mimics of Antimicrobial Peptides from Triaryl Scaffolds

In this report, we describe the synthesis of a new series of small amphiphilic aromatic compounds that mimic the essential properties of cationic antimicrobial peptides using Suzuki-Miyaura coupling. The new design allowed the easy tuning of the conformational restriction, controlled by introduction of intramolecular hydrogen bonds, and the overall hydrophobicity by modifications to the central ring and the side chains. This approach allowed us to better understand the influence of these features on the antimicrobial activity and selectivity. We found that the overall hydrophobicity had a more significant impact on antimicrobial and hemolytic activity than the conformational stiffness. A novel compound was discovered which has MICs of 0.78 μg/mL against S. Aureus and 6.25 μg/mL against E. Coli, similar to the well-known antimicrobial peptide, MSI-78.
