Design and simulation of efficient combinational circuits based on a new XOR structure in QCA technology
2021
AbstractQuantum-dot cellular automata (QCA), due to its unique characteristics like low power consumption, nanoscale design, and high computing speed is considered as an emerging technology, and it can be used as an alternative for CMOS technology in circuit design for quantum computers in the near future. XOR gate has many applications in the design of digital circuits in QCA. In this paper, an efficient novel structure of XOR gate is proposed in QCA. Also, a novel 1-bit comparator circuit, 1-bit full adder, binary to gray and gray to binary convertor code based on the proposed XOR is designed and simulated using QCADesigner 2.0.3. The simulation results demonstrated that the proposed stru…
Assembly and functioning of endophytic bacterial communities in arcto-alpine pioneer plant Oxyria digyna
2019
Plant microbiomes consist of diverse communities of microorganisms, among which bacteria are highly abundant. The microbiomes are crucial for plants as they rely on their microbial associates for many essential functions. The goal of this thesis was to study the functional diversity and assembly rules of endophytic bacterial communities in different plant tissues of the arcto-alpine pioneer plant species, Oxyria digyna. I used high-throughput sequencing and bacterial isolations to characterize the endophytic communities in the leaves and roots of native O. digyna plants (wild plants) and micropropagated aseptic plants (bait plants) in the field. Wild plants and tissue-propagated bait plants…
Il ruolo strategico delle città gateway in Europa. IX Biennale delle città e degli urbanisti europei
2011
La IX Biennale delle città e degli urbanisti europei si è concentrata sul tema delle Gateways in Europa, tema che è stato approfondito nel workshop parallelo Il ruolo strategico delle città gateway in Europa. I relatori del workshop, coordinato da Franco Migliorini (INU), esaminando gli effetti che la globalizzazione sta producendo sul territorio europeo, hanno esposto il quadro generale delle trasformazioni in atto, le problematiche e le questioni ancora aperte ed in continua evoluzione, proponendo possibili soluzioni e spunti di riflessione sulle procedure da attuare, presentando anche esempi di casi di città europee emergenti, di città gateway variamente declinabili. Il riaccentramento d…

Interaction of glutamic-acid-rich proteins with the cGMP signalling pathway in rod photoreceptors.
1999
The assembly of signalling molecules into macromolecular complexes (transducisomes) provides specificity, sensitivity and speed in intracellular signalling pathways. Rod photoreceptors in the eye contain an unusual set of glutamic-acid-rich proteins (GARPs) of unknown function. GARPs exist as two soluble forms, GARP1 and GARP2, and as a large cytoplasmic domain (GARP' part) of the beta-subunit of the cyclic GMP-gated channel. Here we identify GARPs as multivalent proteins that interact with the key players of cGMP signalling, phosphodiesterase and guanylate cyclase, and with a retina-specific ATP-binding cassette transporter (ABCR), through four, short, repetitive sequences. In electron mic…
Mesoporous silica microparticles gated with a bulky azo derivative for the controlled release of dyes/drugs in colon.
2018
[EN] Mesoporous silica microparticles were prepared, loaded with the dye safranin O (M-Saf) or with the drug budesonide (M-Bud) and capped by the grafting of a bulky azo derivative. Cargo release from M-Saf at different pH values (mimicking those found in the gastrointestinal tract) in the absence or presence of sodium dithionite (a reducing agent mimicking azoreductase enzyme present in the colon) was tested. Negligible safranin O release was observed at pH 6.8 and 4.5, whereas a moderate delivery at pH 1.2 was noted and attributed to the hydrolysis of the urea bond that linked the azo derivative onto the external surface of the inorganic scaffold. Moreover, a marked release was observed w…
Alternative feed resources and their effects on the quality of meat and milk from small ruminants
2008
The present paper reviews the quality of meat and milk from sheep and goats offered alternative feeds as a replacement for concentrates. Legume seeds and pods, shrubs, local agro-industrial by-products or novel pasture species are cheap and widely available in Mediterranean countries and are suitable for sheep and goat nutrition. Many of these alternative feed resources (AFR) contain secondary compounds, such as tannins. Tannin-containing feeds result in meat of a lighter colour and tend to increase milk yield and protein content, probably because they protect dietary proteins from ruminal degradation. Conjugated linoleic acid (CLA) content in kid meat can be increased by feeding animals ch…
Glyphosate Sensor Based on Nanostructured Water-Gated CuO Field-Effect Transistor
2022
This research presents a comparative analysis of water-gated thin film transistors based on a copper oxide (CuO) semiconductor in the form of a smooth film and a nanostructured surface. A smooth CuO film was deposited through reactive magnetron sputtering followed by annealing in atmosphere at a temperature of 280 (Formula presented.) C. Copper oxide nanostructures were obtained by hydrothermal synthesis on a preliminary magnetron sputtered 2 nm thick CuO precursor followed by annealing at 280 (Formula presented.) C. An X-ray diffraction (XRD) analysis of the samples revealed the presence of a tenorite (CuO) phase with a predominant orientation of (002). Scanning electron microscopy (SEM) a…
Goodpasture antigen-binding protein (GPBP) y su efector GPBP-interacting protein de 130-kDa (GIP130) dirigen la formación de miofibrillas
2014
Goodpasture antigen-binding protein (GPBP) es una proteína cinasa no convencional que regula la organización del colágeno IV de la membrana basal glomerular, y de la que existen al menos tres isoformas: GPBP-1 que es soluble y exportable; GPBP-2 que es citosólica y se genera por procesamiento alternativo de exones; y GPBP-3 que está asociada a membranas y regula la secreción de GPBP-1. El gen que expresa las proteínas GPBP (COL4A3BP) tiene notable expresión en tejido muscular, en el que GPBP-1 es la isoforma mayoritaria y se encuentra en la línea M de la banda A de las miofibrillas. Durante la miogénesis de mioblastos C2C12 en cultivo hay una progresiva disminución de la expresión de GPBP-2…
Increasing the effectiveness of aggregates for planting sugar beet stecklings to receive elite seeds
2019
Article Planting sugar beet stecklings with planting machine is one of the stages in the technological process of producing elite seeds. The analysis of the experience of using planting units for planting stecklings showed a number of disadvantages: poor quality of planting stecklings without spacing stability and the absence of parameter control; unregulated applying nutrients and granules of water preservation to the roots negatively affect the development of plants. The aggregate having openers of the planting device was designed, and the system of supplying the spray of nutrients and growth stimulator is envisaged. The technological process is conducted in the following way: during the …
