Value creation through innovation: Renewable energy community
No full textInnovation has become in recent years a tool to promote and allow the creation of value, that is, the ability of a company or a company to generate utility, wealth, and growth. In this chapter, the contribution of innovation in decarbonization and in combating the climate crisis is illustrated, paying particular attention to the role of renewable energy communities. They are classified as a means capable of guaranteeing environmentally friendly wealth that aims not only at maximizing profit but also at creating economically sustainable models. Currently, digitalization allows a connection to nodes, peer to peer, while initially, the model was based on one-to-many transmissions, which did not allow the decentralization that are the basis of renewable energy communities; they also have a strong social impact, aiming to increase the production and consumption of energy by renewable sources, with the aim of achieving high levels of energy efficiency within society
The importance of innovation diffusion in the renewable energy sector
No full textIn the last decade, one of the most discussed topics globally concerns the difficult management of climate change and the need for an energy and cultural transition that pays attention so as not to increase territorial inequalities. This chapter aims to provide a clear and comprehensive picture of the importance of innovation in the renewable energy sector and the role of their deployment to ensure climate change mitigation and sustainable growth. The authors will start from the environmental Kuznets curve (EKC) and then examine the metabolism of current societies, focusing on the trend of the diffusion of technological innovation and its contribution to the energy transition
Relation Between Harappan And Brahmi Scripts
No full textAround 45 odd signs out of the total number of Harappan signs found make up almost 100 percent of the inscriptions, in some form or other, as said earlier. Out of these 45 signs, around 40 are readily distinguishable. These form an almost exclusive and unique set. The primary signs are seen to have many variants, as in Brahmi. Many of these provide us with quite a vivid picture of their evolution, depending upon the factors of time, place and usefulness. Even minor adjustments in such signs, depending upon these factors, are noteworthy. Many of the signs in this list are the same as or are very similar to the corresponding Brahmi signs. These are similarities that simply cannot arise from mere chance. It is also to be noted that the most frequently used signs in the Brahmi look so similar to the most frequent Harappan symbols. The Harappan script transformed naturally into the Brahmi, depending upon the factors channelizing evolution of scripts
Central Asian Brahmi palaeography: the relationships among the Tocharian, Khotanese, and old Turkic Gupta scripts
No full textBibliography: p. 154-159.It has been assumed that Tocharian and Khotanese Brahmi
writing were not related and that both systems arose through Indian missionary activity. But since the Central Asians had been Buddhist for at least 500 years, it is here maintained that the introduction and transmission of the Brahmi were strictly indigenous developments. It is suggested that two cultural events happening in India influenced the Khotanese to relinquish Kharosthi script and the Gandhari Prakrit
..
as the media of administration and religion: the supercedence of the Kharo??ihI by the Brahmi, and the evolution of a hybrid form of Sanskrit as the lingua franca of Buddhism.
In order to prove and illustrate the relationships among
the Central Asian Brahmi scripts, use is made not only of character morphology but also of orthographic principles. An examination of
the Turkic Brahmi reveals it to have been the intermediary between
the Khotanese Formal and the Tocharian Slanting Gupta.. The dual function of the diaeresis in Tocharian as vowel and virama marking
is shown to be the result of immitation of the Turks. Similarly,
the parallel dual function of the Tocharian 'doublets' as vowel and virama indicators is also demonstrated as having had a Turkic (and Khotanese) origin
Composition and antioxidant and antimicrobial activity of the volatile oils from Olea europaea L. fruit and stem
No full textThe aims of this study was to analyze the chemical composition of fruits and stem volatile oils of Olea europaea L. cv. Chemchali and to test the efficacy of volatile oils against four pathogenic bacteria and four phytopathogen strains and their antioxidant activity. The GC-MS analysis revealed 38 compounds representing 88.5 and 73.6% of the total oils containing 3-ethenylpyridine (12.5%), (E)-2-decenal (11.4%) and 2-ethylbenzaldehyde (7.7%) in fruit and nonanal (9.9%), (E)-2-decenal (9.6%) and benzyl alcohol (9.00%) in stem as major components, respectively. The antibacterial and antifungal activities of stem volatile oils were relatively good. Therefore, the stem of Olea europaea L. demonstrated higher activities against tested fungi and bacteria than the fruit. The DPPH and ABTS-radical-scavenging activities of the oils showed that the lowest EC50 value was detected in volatile oil from fruit
Antioxidant activity of the volatile oils and methanol extracts from olive stems
No full textThis study was designed to examine the chemical composition and antioxidant activities of the volatile oils and methanol extracts of Olea europaea L. (cvs) chemlali and neb jmel stems. GC and GC–MS analyses of the volatile oils resulted in the identification of 38 and 35 compounds, representing 91.1 and 87.4 % of the volatile oils. Phenylethyl alcohol was found in the volatile oil of each cultivar, which was also the major volatile component of cv. chemlali and cv. neb jmel stems. Besides benzyl alcohol, methyl salicylate and 3-ethenylpyridine were the main volatile compounds of cv. chemlali, while nonanal, 3-ethenylpyridine and benzyl alcohol of cv. neb jmel stems were also the main constituents. Significant differences were also found in total tannin contents among two cultivars, representing 8.10 mg CEQ/g DW in cv. chemlali and 20.47 mg CEQ/g DW in cv. neb jmel. The highest contents of total phenols and o-diphenols were observed in stems extracts of cv. neb jmel (78.26, and 9.56 mg/100 g, respectively). The HPLC profiles for methanol extracts from stems of cv. chemlali and cv. neb jmel showed that oleuropein, vanillic acid and gallic acid were the predominant free phenolic compounds. Antioxidant activities of the volatile oils and the methanolic extract from stems parts
were evaluated by DPPH and ABTS? radical-scavenging activity assays. In all tests, methanolic extracts obtained from stems parts showed better antioxidant activity than volatile oils. Principal components analysis of the phenolics content and antioxidant activities showed discrimination between methanol extracts of the two cultivar

Circular Economy Business Models: The Complementarities with Sharing Economy and Eco-Innovations Investments
No full textThe transition from the linear economy to the circular economy exhibits some criticalities
that can be solved through the identification of factors pushing and pulling the transition itself. By
adopting a public good perspective in analysing the main features of the circular business models, this
study underlines how the sharing economy business models are well integrated and complementary
to some features of the circular economy, representing a strong pulling factor. Other loops of the
circular economy need an explicit push factor, individuated in a strong impulse to eco-efficiency, to
be reached through consistent incentives to invest in R&D for eco-innovations. Seven case studies are
investigated in their aims, feasibility and implementation to support the interpretative framework
Knowledge spillovers and technical efficiency for cleaner production: An economic analysis from agriculture innovation
No full textThe objective of the analysis is to investigate the production efficiency in the USA and Europe through the channel of knowledge spillovers from technological innovation in the agricultural sector. Since the empirical evidence concerning the climate change effects on the production efficiency is yet weak, the paper further contributes to the literature attempting to bridge this gap. To this end, the non-parametric Data Envelopment Analysis (DEA) empirical methodology and Tobit regression are developed on the basis of a sector-based panel data set over the time period of 2002–2017. In particular, the empirical results evidenced a negative effect of land use spillovers on efficiency indicator for American firms and a positive effect for European ones. The study findings are innovative and invaluable to generate policy implications for the investigated country governments particularly in terms of developing industrial strategy instruments in the agricultural field: Government is supposed to establish the special funds to encourage the firms to expand innovation activities in their own production process and the investment of R&D is expected to increase, which can further improve the productivity and reduce the reliability of knowledge spillovers. Finally, it is important that the results are scalable, and the model could be extended also to developing countries
Efficacy of Brahmi vati in generalised anxiety disorder – Randomized double blind comparative clinical trial
No full textBackground: Generalized Anxiety Disorder (GAD) is the most common anxiety disorder. GAD has high comorbidities and it can affect social, professional and personal life. Ayurvedic medicine, Brahmi vati is explored for the possible role in management of GAD and is compared to Manasmitra vataka. Aim: To evaluate the efficacy of B. vati on Generalized Anxiety Disorder. Methods: A randomized double blind controlled trial, with total 56 patients meeting the DSM V criteria of GAD between 20–60 years of age and either sex participated in the study. Participants were randomly divided into two groups, Brahmi group received capsule B. vati 500 mg and Manasmitra group received capsule M. vataka 500 mg thrice a day with water for 45 days. Assessments were conducted through various clinical parameters such as Hamilton Anxiety Rating Scale (HARS), GAD 7 scale (GAD 7), Beck Depression Inventory scale (BDI), Epworth sleepiness scale (ESS), Pittsburgh Sleep Quality Index (PSQI), WHO Quality of Life- BREF (WHOQOL-BREF), Clinical Global Improvement scale (CGI). Blood variables including Haemoglobin, Erythrocyte Sedimentation Rate (ESR), Liver Function Test (LFT) and serum creatinine were assessed before and after the study. Assessments during intervention were conducted on every 15th day. Results: Study results indicate that both B. vati and M. vataka were comparable and each produced significant improvement (p < 0.001) in HARS, GAD-7, BDI, ESS, PSQI, WHOQOL-BREF and CGI. Brahmi vati also produced significant decrease in systolic (p = 0.002) and diastolic (p < 0.001) blood pressure. Both groups showed good safety profile evaluated through the assessment of serum creatinine levels and LFT. Conclusion: B. vati and M. vataka were effective, safe and comparable in the management of GAD. Warrants further studies
