The people behind the papers – Léa Rambaud-Lavigne, Namrata Gundiah, Arezki Boudaoud and Pradeep Das
No full textInternational audienceThe shoot apical meristem is a key stem cell niche in plants, and proper stem cell maintenance is partly regulated by CLAVATA3 (CLV3). Without CLV3 meristems overgrow, but the mechanistic basis of this phenotype was unclear. A new paper in Development suggests that CLV3 modulates the physical properties of meristematic stem cells, and that these properties help shape meristem morphology. To learn more about the story behind the paper, we caught up with first author Léa Rambaud-Lavigne and corresponding authors Namrata Gundiah, Arezki Boudaoud and Pradeep Das
Low Phase Noise Wide Tuning Range LC Oscillator for RF Application using Varactor Bank
No full textThis paper presents the design of a QVCO (Quadrature voltage controlled oscillator) with high tuning range and low phase noise for Radio Frequency applications. The proposed VCO has been designed to produce quadrature signal by using cross coupled topology. Extra pair of MOSFETS are added to improve the quality factor of the LC tank, which helps to improve the phase noise. The tuning range of VCO ranges from 3.8 GHz to 4.52 GHz, which is nearly 20%. Additionally, the obtained phase noise is -120.31 dBc/Hz at 1MHz offset frequency. The observed power dissipation is 13.21 mW
The Surabhi Theatre–An Oasis of Telugu Theatre
Get PDFThis document is a thesis submitted in partial fulfillment of the Master of Arts degree in Theatre Arts. It is a detailed account of author Pradeep Aswini Gurrala’s study of the Surabhi Theatre in Telangana, India. The thesis follows the journey of a 134-year-old theatre company in four chapters: puppet show to stage show; the evolution of the Surabhi Theatre; the decline of Surabhi Theatre; and Surabhi Theatre as a cultural heritage.

The combined incidence of taxes and public expenditures in the Philippines
Get PDFIncidence studies of fiscal policy in developing countries typically examine either the distribution of tax burdens or the incidence of public expenditures. But the central issue for policymakers is the combined or net incidence of fiscal activities. One reason that combined incidence studies are so rare is that they require detailed data on both taxation and public spending. The authors show that the net incidence of fiscal policy in a country with average data - the Philippines - can be estimated using a variety of data sources and tools, using simplifying assumptions. For 20 years, the Philippine economy has experienced a series of balance of payments crises triggered by fiscal crises. It has had an unsatisfactory record of poverty alleviation. The authors examine net fiscal incidence to find out how poverty will be affected by the rise in taxes and the cut in spending. They found that: 1) the incidence pattern of taxes is basically neutral. Contrary to expectations, indirect taxes are only slightly regressive; and 2) it is the pattern of expenditures that drives the combined incidence, which is progressive.Public Sector Economics&Finance,Environmental Economics&Policies,Health Systems Development&Reform,Economic Theory&Research,Health Economics&Finance,Environmental Economics&Policies,Public Sector Economics&Finance,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform

Biochar for horticultural and agricultural applications using high temperature torrefaction technology: Biochar for horticultural and agricultural applications using high temperature torrefaction technology

Currently the major global sustainability issue stems from the sourcing of virgin wood chips from dense forests for pellet production. An alternative is to use residual biomass from agriculture or forestry, which is produced in large volumes, to produce different products that range from biofuels to chemicals via thermochemical conversion technologies. Among thermochemical technologies, torrefaction is a promising route to produce solid biofuel known as biochar. With an increasing potential for biomass production coupled with an increased scrutiny on the use of biomass as a green fuel, the need for alternative clean applications for the biochar is critical. The aim of this study is to investigate new and novel agricultural residues or other waste streams to produce biochar using high temperature (350 °C) torrefaction technology. The obtained biochar is evaluated experimentally to determine the best feedstocks out of the ones that are selected from a performance and cost point of view for horticultural applications. . This research aims to provide a clear and useful analytical tool which will benefit the scientific community to select suitable biomass materials based on material properties and end applications. The efficacy for the various torrefied biomass feedstocks on the soil and its stability are tested. Overall, about 50 different biomass feedstocks were identified and evaluated based on past performances from literature. The top 10 best performing feedstocks were sourced and subjected to various physical and chemical characterization tests with a specific focus on soil remediation. The selected materials were torrefied in a fixed bed pilot reactor Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDS), Brunauer–Emmett–Teller (BET) and pH measurements. Ultimately the feedstocks were scored and ranked from best to worst performing biochar for soil remediation and sequestration-based applications. The results of this project indicate potential for biochar production from woody, grassy and other processed materials that could help to remove the dependence on evergreen forests and wood chips. The system proposed in this work could also yield negative emissions since the feedstocks are residual flows and the biochar is going to be used in the soil.Electrical Engineering | Sustainable Energy Technolog
