No full text© 2022, The Author(s).How particular bonds form in quantum materials has been a long-standing puzzle. Two key concepts dealing with charge degrees of freedom are dimerization (forming metal-metal bonds) and charge ordering. Since the 1930s, these two concepts have been frequently invoked to explain numerous exciting quantum materials, typically insulators. Here we report dimerization and charge ordering within the dimers coexisting in metallic NaRu2O4. By combining high-resolution x-ray diffraction studies and theoretical calculations, we demonstrate that this unique phenomenon occurs through a new type of bonding, which we call Z-type ordering. The low-temperature superstructure has strong dimerization in legs of zigzag ladders, with short dimers in legs connected by short zigzag bonds, forming Z-shape clusters: simultaneously, site-centered charge ordering also appears. Our results demonstrate the yet unknown flexibility of quantum materials with the intricate interplay among orbital, charge, and lattice degrees of freedom.11Nscopu
Synthesis of new quinoline derivatives based on mono-functional polybenzoxazines for oil-water separation, anti-corrosion and antibacterial applications
No full textIn the present work, novel and effective quinoline-based polybenzoxazines coatings were prepared on cotton fabrics and mild steels to improve the hydrophobic properties and corrosion resistance, respectively. For this purpose, four quinoline containing mono-oxazine-based benzoxazines were synthesized using 8-hydroxyquinoline (Q), and various monoamines, such as: butylamine (ba), hexylamine (ha), octylamine (oa) and aniline (a). The molecular structure of the benzoxazine monomers was verified by 1H-NMR and FTIR spectroscopy. The effect of the aliphatic and aromatic functional groups of the benzoxazines on oxazine ring-opening curing was investigated, and the influence of their corresponding materials on thermal and morphological properties was also elucidated. These quinoline-based monomers have been successfully coated onto the surface: i) cotton fabrics to be used as a water – oil separation method; and ii) mild steel as inhibitor of the corrosion. In this sense, cotton fabric coatings exhibited highly hydrophobic properties (contact angle from 124° to 139°), and subsequently the water oil-separation efficiency was measured to the material that presented the highest contact angle (Poly Q-oa), obtaining a 91% separation efficiency. For benzoxazines coatings on mild steel, impedance tests have indicated that these polymers are corrosion inhibitor effectives. Finally, the antibacterial properties of the quinoline based benzoxazines was also analysed, indicating good antibacterial.Fil: Selvaraj, Kumar.

Kumar & F. N. Rasm. in Nordic J. Bot. 7: 409. 1987. Typus: INDIA. Kerala: Ponmudi, Trivandrum Dist., 950 m, 25.X. 1983, C. Sathish Kumar CU 36960 (holo-: TBGT; iso-: C, CALI), syn. nov.. Distribution. – India: Kerala, Maharashtra (fide JAYAWEERA, 1981;P UNEKAR, 2002);SriLanka. Note. – SATHISH KUMAR & RASMUSSEN (1987) distinguished C. seidenfadeniana from C. parvifolia on the basis of epichile with entire lobules and 2 conspicuous tufts of hairs at its base. The authors mentioned that the material of C. parvifolia was very scarce from India and they could consult only 3 old herbarium specimens including the type (Loddiges s.n., K) which was in very bad condition. However, it has been found that the holotype including its associated illustrations of flower and dissected floral parts (on the type sheet) is sufficient for its purpose and there is no need of epitypification at present. During the present work, critical study of the live specimens of C. seidenfadeniana provided by Dr. C. Sathish Kumar (first author of C. seidenfadeniana) revealed that the minute tufts of hairs at the base of epichile can be seen only in live, pickled or very well preserved specimens but not in the old herbarium specimens. The present study also reveals that the margin of the epichile lobules of C. seidenfadeniana varies (Fig. 1) from nearly entire to 2-4 lacerate which clearly indicates that C. seidenfadeniana and C. parvifolia are the same species. Thus, C. seidenfadeniana is treated here as synonym of C. parvifolia. In spite of author’s personal visit to CALI and TBGT, the holotype and isotype(s) of C. seidenfadeniana could not be located as claimed in the protologue. Dr. Olof Ryding, Curator of Vascular Plants of C also confirmed the unavailability of any type specimen of C. seidenfadeniana in C. Surprisingly, a specimen bearing the same collection number and field data (excepting the date which is prior to publication of C. seidenfadeniana) as that of the holotype and isotypes of C. seidenfadeniana has been located at K. In absence of all the designated types (holotype and isotypes), the K-specimen may be selected as lectotype (if there is no doubt that it was actually used while describing C. seidenfadeniana) or as neotype of C. seidenfadeniana. For the time being the lecto-or neotypification has not been done in the present paper with a hope that the types may be found in near future. This rare species is presently grown and conserved in the Orchidarium of Tropical Botanic Garden and Research Institute, Thiruvananthapuram, Kerala, India by Dr. Sathish Kumar and his co-workers.Published as part of Bhattacharjee, Avishek, 2012, On the status of some species of Cheirostylis Blume (Orchidaceae) from India, pp. 31-35 in Candollea 67 (1) on page 32, DOI: 10.15553/c2012v671a3, http://zenodo.org/record/570865
Decoding chemical profiles and biological activities of aerial parts and roots of Eryngium thorifolium Boiss by HPLC-MS/MS, GC-MS and in vitro chemical assays
No full textEryngium species are widely distributed and primarily utilised for medicinal and culinary purposes. This study aimed to evaluate the chemical composition, antioxidant, enzyme inhibition, and cytotoxic properties of various extracts from the aerial parts and roots of E. thorifolium Boiss. The chemical composition of ethyl acetate, methanol, and water extracts was analysed using High-Performance Liquid Chromatography-Electrospray Ionization Tandem Mass Spectrometry (HPLC-ESI-MS/MS), while the hexane ones were examined using Gas Chromatography-Mass Spectrometry (GC-MS) analysis. The most predominant class of secondary metabolites identified were fatty acid amides and flavonoids as hexose conjugates. Extracts from the aerial parts exhibited the highest antioxidant activity, with the methanol and water extracts showing the best anti- 2,2-diphenyl-1-picrylhydrazyl (DPPH) (21.9 mg trolox equivalent (TE)/g) and anti- 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) (89.26 mg TE/g) activities. Enzyme inhibition tests revealed that the hexane extract from the roots had the highest anti-acetylcholinesterase activity (2.49 mg galantamine equivalent (GALAE)/g). Additionally, both the hexane and ethyl acetate extracts from the aerial parts demonstrated the highest antibutyrylcholinesterase activity (3.13 and 3.71 mg GALAE/g, p ≥ 0.05). At a concentration of 100 μg/mL, all extracts from the roots and aerial parts, except the water one, displayed potent cytotoxicity against the human embryonic (HEK 293) and murine macrophages (RAW 264.7) cell lines, with cellular viability ranging from 1.66 to 2.62% compared to the control (0.5% DMSO) (89.2 and 95.1%, respectively). Through network pharmacology and molecular docking, the phytochemicals of E. thorifolium show significant potential as natural compounds targeting key proteins involved in cancer progression, including Bcl-2, c-KIT, PI3K, and AKT. Their binding affinities and predicted interactions highlight their possible therapeutic applications in managing various cancers. These findings suggested E. thorifolium is a promising source of phytochemicals targeting specific oxidative stresslinked diseases, including cancer, diabetes and neurodegenerative disorders
Trust the process : Role of trust in creative problem solving: A guidebook to empower individuals to build trustful relationships by establishing the role of trust in creative problem solving used in design consultancy - client projects
No full textTraditionally, conventional consultancies provide operational guidance to customers. However, market demands have shifted towards a human centred approach, leading to an increase in design consultancies. Design consultancies deliver not only great results but also introduce innovative ways of thinking through a process-driven approach differing from the result-driven process that clients were used to. The new ways of working poses a new challenge of rising uncertainty. Building trust with client organization reduces the inherent risk of working together, thereby building a stronger relationship. This helps consultancies gain credibility and create mutual reliability, improving brand loyalty and customer retention.Similarities with the creative problem solving process and trust building process were drawn to form a template. Further the research was scoped to see trust building from an individual standpoint, i.e. design consultant being the facilitator in enabling clients build trust towards them. The project was set with the research question of “How do individuals in design consultancies help build trustful relationships with clients amid the constant shift in design perceptions? “From empirical and theoretical analysis, eight driving factors and many trust building actions were identified. Apart from this, the research identified a lack of trust building awareness, how it is important to build trust around your context and with yourself. Further a trust building journey was developed that establishes how trust is built in a step wise approach and how it can be empowered for skill development for individuals seeking to work in a consultancy environment. The design solution is a guidebook developed to raise awareness and help surface the factors necessitated towards trust building through narrative-based learning. Narratives of working professionals experiences highlighting suitable actions taken for trust development helps individuals reflect on their ways of working and embed new actions that improves trust building.

Artificial Neural Network Based Method for Classification of Gene Expression Data of Human Diseases along with Privacy Preserving
No full textIn this paper, the author introduces a classification approach using Artificial Neural Network(ANN) with Back-Propagation learning technique for human diseases like Cancer and heart problems from clinical diagnosis data. Clinical diagnosis is done mostly by experienced doctors with expertise in this field. In many cases, the test results are not effective towards the diagnosis of the disease. The author is particular about the wrong diagnosis which leads to a wrong treatment. The author is using Artificial Neural Network technique to classify the disease with reduced number of DNA sequence. The accuracy is differing based on the training data set and validation data set. The other major issue is the privacy preserving of the patients. As we are sharing the critical data from clinical diagnostic centers, there is good chance of patient’s anonymity is revealed. To avoid this, the author is using a simple Privacy Preserving in Data Mining (PPDM) technique to crypt the identity of the patients as well as the critical data and discloses only the required data like DNA sequence to the research team, as they are not much interested in the identity or the owner of the diagnosis report.</jats:p
Scalable business model of digital solutions, to assist elderly patients with mild cognitive impairment
Get PDFLAUREA MAGISTRALE-This project aims at creating a scalable business model (BM) and identify the variable that should be considered when developing the BM for the digital solutions that assist elderly population with mild to moderate cognitive impairment. This project work is part of a larger project called the DECI, whose aim is to implement and sustain these technologies in the various technologies. In this section we will also discuss how the scalable BM created in this project work can be expanded to the various countries in the study. Which is the next phase after this project in the DECI initiative.
The aim of the project is reached though a through literature analysis followed by organizing Co-creating works shops (CCWs) where the various actors in the project – patients, caregivers and technology partners get together to identify and discuss the outcomes of the literature analysis and gather know-how. One CCW has been conducted in each country in order to collect information for the study. In this report work, only the CCW conducted in Italy is under scope.
First, using the STOF framework (Bouwman et al., 2008) the four domains of service, Technology, organization and Finance are considered in order to get a macro view on the points that should be considered when formulating the BM. Then, the learnings from the literature analysis and key points from the STOF framework will be used to populate the Business Model Canvas described by Osterwalder and Pigneur (2010).
In order to accomplish this study. First, we need to define the customer segment that we will be targeting during the study and also define which patients will be included in this study. Second, the different digital solutions that will be used to tackle the needs of the patients with mild to moderate dementia (MCI) needs to be defined. These studies are part of the DECI initiative and for this project work they were considered as an input. As the work on the both the projects were run in parallel, the literature analysis done during this project work also contributed to the literature analysis done for the other project in DECI, which was defining the digital technologies.
When creating the BM, it was found that the key actors are not only the patients with MCI. We also need to take the perspective of the caregivers, healthcare specialist and organizations. As all the actors work closely with each other. Any focus given to only one of the actors will affect the choices for the other group of customers. Furthermore, during the CCWs it was noted that the caregivers have a dual role in the system. They are both the customers and as well as the channel through which we deliver the services. The value propositions for the BM are numerous and they are complimentary to each other. For example, taking the example of the monitoring system and integration between the various technologies. It is important that the integrations between the systems are good to provide a good monitoring service.
Lastly, the most important take away message of this project is that each country in the study should strive for its own BM. In order to come to the country specific BM, the scalable BM can be considered as a reference material. The reasons why each of the countries should have their own BM is because the set-up of the system depends on the level of personalization required and, on the country, specific health care system. Furthermore, it is also influenced by the government actions, in terms of incentives, awareness campaigns and norms. Therefore, the context of application heavily influences the application of the business model and this should be considered when applying the BM in the various countries. This study will be carried out in the next phase of the DECI project. For this study to be carried out the blueprint of the BM created in this project will be used
