Analysis of pollen germination performance of pistachio hybrids and their male parents
No full textThis study was carried out at the hybrid pistachio plot of the Pistachio Research Institute, Turkey. Pollen of pistachio hybrids, by hybridizations of Kallahghochi, Siirt and Ohadi female cvs and Uygur, Atli and Kaska male cvs, was used in the study. The study compared the pollen germination percentage and pollen tube length of some pistachio male cvs with their offspring and showed that pollen germination of male parents was generally higher than that of their hybrids, except for Siirt x Uygur. The highest pollen germination percentage among the all hybrids and their male parents was obtained from Siirt x Uygur-Hybrid-2 (98.89%) and followed by Siirt x Kaska-Hybrid-2 (97.85%), which showed rather high pollen germination rates, while Siirt x Atli-Hybrid-2 had the lowest pollen germination (82.41%). The pollen tube length of the genotypes ranged from 680 µm (Ohadi x Kaska-Hybrid-3) to 1210 µm (Kallahghochi x Atli-Hybrid-1 and 2) and pollen tube development of Uygur was lower than of their offspring. In terms of pollen performance, Siirt x Kaska-Hybrid-2 was determined as the best F1 hybrid. The results of the study suggest that pollen germination and pollen tube growth may indicate pollinator performance of hybrid pistachio trees

Words standarization by non-parametric statistical methods
No full textThe author has dealt with amalgamation of pattern primitives and its justification in language description, in earlier studies [4] & [5]. Here an attempt is being made to apply distribution free techniques, more commonly known as non-parametric statistical methods in finding the confidence coefficient and adjustment factor for obtaining the standard form of words taken from different sub-dialects.Dhami, H.S..

Metafore spaziali della conoscenza di sé nei dialoghi di H.S. Skovoroda : fonti patristiche
No full textSpatial Metaphors for Self-knowledge in the dialogues of H.S Skovoroda. Patristic Sources
In this paper the Author analyzes some spatial metaphors informing H.S. Skovoroda’s representation of self-knowledge as a dynamic process. Knowledge of the true self – which is one of the recurring themes in the Ukrainian philosopher’s oeuvre – is often portrayed as tension between open (e.g. streets, markets, the sky, the planets…) and closed spaces (e.g. the house, the room), with the ‘home’ being a symbol for the soul. As man seeking communion with God has to abandon what lies outside his inner self, the authentic gnoseological process is represented as an introverted movement through symbolic space. Broadly speaking, this very opposition harks back to Philo of Alexandria and Patristic thought, whose anti-physicist stance shaped their rejection of the phenomenological world as an ‘interior vs. exterior’ contrast. Furthermore, the broader biblical context in which those spatial terms appear is also taken into account, while demonstrating Skovoroda’s partial dependence on Patristic models. The fi nal part of the paper argues that the scheme underlying Neo-platonic emanation – which is itself to be considered as an oscillation between unity and dispersion – appears to be a symbolic model for Skovoroda’s spatial representation of self-knowledge
Constitutive modeling of deformation behavior of high-entropy alloys with face-centered cubic crystal structure
No full textA constitutive model based on the dislocation glide and deformation twinning is adapted to face-centered cubic high-entropy alloys (HEAs) as exemplified by the CrMnFeCoNi system. In this model, the total dislocation density is considered as the only internal variable, while the evolution equation describing its variation during plastic deformation is governed by the volume fraction of twinned material. The suitability of the model for describing the strain hardening behavior of HEAs was verified experimentally through compression tests on alloy CrMnFeCoNi and its microstructure characterization by electron backscatter diffraction and X-ray diffraction using synchrotron radiation. ? 2017 The Author(s).

Superior pre-osteoblast cell response of etched ultrafine-grained titanium with a controlled crystallographic orientation
No full textUltrafine-grained (UFG) Ti for improved mechanical performance as well as its surface modification enhancing biofunctions has attracted much attention in medical industries. Most of the studies on the surface etching of metallic biomaterials have focused on surface topography and wettability but not crystallographic orientation, i.e., texture, which influences the chemical as well as the physical properties. In this paper, the influences of texture and grain size on roughness, wettability, and pre-osteoblast cell response were investigated in vitro after HF etching treatment. The surface characteristics and cell behaviors of ultrafine, fine, and coarse-grained Ti were examined after the HF etching. The surface roughness during the etching treatment was significantly increased as the orientation angle from the basal pole was increased. The cell adhesion tendency of the rough surface was promoted. The UFG Ti substrate exhibited a higher texture energy state, rougher surface, enhanced hydrophilic wettability, and better cell adhesion and proliferation behaviors after etching than those of the coarse- and fine-grained Ti substrates. These results provide a new route for enhancing both mechanical and biological performances using etching after grain refinement of Ti. ? The Author(s) 2017.115Ysciescopu

Using Topic Models to Mine Everyday Object Usage Routines Through Connected IoT Sensors
No full textWith the tremendous progress in sensing and IoT infrastructure, it is foreseeable that IoT systems will soon be available for commercial markets, such as in people's homes. In this paper, we present a deployment study using sensors attached to household objects to capture the resourcefulness of three individuals. The concept of resourcefulness highlights the ability of humans to repurpose objects spontaneously for a different use case than was initially intended. It is a crucial element for human health and wellbeing, which is of great interest for various aspects of HCI and design research. Traditionally, resourcefulness is captured through ethnographic practice. Ethnography can only provide sparse and often short duration observations of human experience, often relying on participants being aware of and remembering behaviours or thoughts they need to report on. Our hypothesis is that resourcefulness can also be captured through continuously monitoring objects being used in everyday life. We developed a system that can record object movement continuously and deployed them in homes of three elderly people for over two weeks. We explored the use of probabilistic topic models to analyze the collected data and identify common patterns.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Pattern Recognition and Bioinformatic
