Bioinformatic Analysis Of Solanaceae Chloroplast Genomes And Characterization Of An Arabidopsis Protein Disulfide Isomerase In Transgenic Tobacco Chloroplasts 2006

Throughout history, traditional plant breeding has been used to provide resistance to pests, disease and other forms of environmental stress, as well as to increase yield and improve upon quality and processing attributes. Over the last decade, the advancement in sequencing technology and bioinformatic analysis has unleashed a wealth of knowledge about chloroplast genetic organization and evolution. The lack of complete plastid genome sequences is one of the major limitations in advancing plastid genetic engineering to other useful crops. This is due to the fact that plastid genome sequences are essential for the identification of endogenous regulatory sequences and optimal sites for homologous recombination. Analysis of four Solanaceae genomes revealed significant genetic modifications in both coding and non-coding regions. Repeat analysis with Reputer revealed 33 to 45 direct and inverted repeats ≥ 30bp with at least 90% homology. All but five of the 42 repeats shared among all four genomes were located in the exact same genes or intergenic regions, suggesting a functional role. Intergenic analysis found four regions that are 100 percent identical in all four Solanaceae genomes. Such highly conserved intergenic regions are ideal targets for multi-species transformation cassettes. Protein disulfide isomerases (PDI) are a family of proteins known to function as molecular chaperones and aid in the formation of disulfide bonds during protein folding. They contain at least one thioredoxin domain used for the formation, isomerization, and reduction/oxidation of disulfide bonds. Bioinformatic analysis identified 13 PDI-like (PDIL) proteins found in Arabidopsis that contain at least one thioredoxin domain. In addition to the above-mentioned characteristics, PDIs have been shown to be directly involved in the translational regulation of the psbA mRNA in response to light and could potentially increase the
Synthesis of Protein and Nucleic Acids in J'7ivo and in Jâ€•itro1

(BCNU; NSC 409962) was found to be one of the most effective anti-icu kemic agents of a number of nitrosoureas that were tested agaimist murinc leukemia (28, 33), and it was found to be effective against both intraperitoneal L1210 leukemia and intracerebral L1210 leukemia. Its activity was manifest whether it was administered i.v. , i.p., s.c. , or p.o. Be cause a subline of a hamster plasmacytoma that was re sistant to cyclophosphamide was also resistant to BCNU, it was suggested that this compound might function as an alkylating agent (28) ; cross resistance to alkylating agents was also observed for a strain of Escherichia coli that was resistant to BCNU (27). This combination of properties indicated that this compound might be a potentially useful
Innovation and Technology in the Phosphate Industry Triboelectric belt separator for beneficiation of fine minerals

Separation Technologies, LLC (ST) has developed a processing system based on triboelectric charging and electrostatic separation that provides the mineral processing industry a means to beneficiate fine materials with an entirely dry technology. The environmentally friendly technology can eliminate wet processing and required drying of the final material. The process requires little if any pre-treatment of the material other than grinding and operates at high capacity – up to 40 tonnes per hour by a compact machine. Energy consumption is low, approximately 1 kWh/tonnes of material processed. Since the only potential emission of the process is dust, permitting is typically relatively easy. In contrast to the other available electrostatic separation processes that are typically limited to particles greater than 75 μm in size, the ST belt separator is ideally suited for separation of very fine (<1 μm) to moderately coarse (300 μm) materials with very high throughputs. The triboelectric particle charging is effective for a wide range of materials and only requires particle – particle contact. The small gap, high electric field, counter current flow, vigorous particle-particle agitation and self-cleaning action of the belt on the electrodes are the critical features of the ST separator. The high efficiency multi-stage separation through charging / recharging and internal recycle results in far superior separations and is effective on fine materials that cannot be separated at all by conventional electrostatic techniques. Since 1995, this triboelectric technology has been extensively used for the beneficiation of coal fly ash with eighteen separators in place and over 130 machine-years of operation at locations in North America and Europe. The technology has been also successfully applied to the beneficiation of a variety of minerals including calcium carbonates, talc, and potash. Recently, dry electrostatic separation has been successfully demonstrated for beneficiation of phosphate ores. © 2014 The Authors. Published by Elsevier Ltd.

The Analog Data Assimilation

AbstractIn light of growing interest in data-driven methods for oceanic, atmospheric, and climate sciences, this work focuses on the field of data assimilation and presents the analog data assimilation (AnDA). The proposed framework produces a reconstruction of the system dynamics in a fully data-driven manner where no explicit knowledge of the dynamical model is required. Instead, a representative catalog of trajectories of the system is assumed to be available. Based on this catalog, the analog data assimilation combines the nonparametric sampling of the dynamics using analog forecasting methods with ensemble-based assimilation techniques. This study explores different analog forecasting strategies and derives both ensemble Kalman and particle filtering versions of the proposed analog data assimilation approach. Numerical experiments are examined for two chaotic dynamical systems: the Lorenz-63 and Lorenz-96 systems. The performance of the analog data assimilation is discussed with respect to classical .
A New Home Gateway Design and a Sensor-Based Smart Home Application Including Privacy Protection

— In this study, a new SIM900 GSM / GPRS module card has been designed. Also, a new home gateway has been designed and implemented by combining the newly designed module with sensor nodes previously developed by us. In addition, this home gateway and sensor nodes are used together to implement a smart home application. In the application, temperature-humidity, light, air, water and motion sensors are used. Users can control and monitor both location-based and sensor-based. A secure communication is established between the sensor nodes and the home gateway with AES encryption algorithm. The work is an originality because it includes both a new home gateway design, smart home application and privacy protection. This work will be beneficial to smart home users and practitioners.
Mineralogical Zoning in a Scapolite-Bearing Skarn Body on San Gorgonio Mountain , California

Concentrically zoned skarns on Mt. San Gorgonio have been studied in detail from the point of view of field and petrographic relations. The skarns are mineralized blocks of marble of the Precambrian San Gorgonio Igneous-Metamorphic Complex, which are within the contact zone between the Complex and the Middle Jurassic Cactus Quartz Monzonite. They consist of cores of calcite-forsterite-diopside marble, surrounded by concentric zones of diopside, actinolite * epidote * calcite + quartz, epidote + garnet * calcite * quartz, and scapolite + calcite + quartz. The genesis of the skarns involved three steps. (l) Regional metamorphism formed tremolite and forsterite from calcite, dolomite, and quartz. (2) The intrusion of the quartz monzonite stabilized diopside * forsterite relative to tremolite * calcite. Reaction between quartz monzonite and marble resulted in the formation of a zone of diopside * wollastonite and a zone of sodic scapolite, by the diffusion of Ca, Mg, and Si across the original contact. Components rejected from this zone formed ferroan diopside in the scapolite zone and in the quartz monzonite, and altered the scapolite to a more calcic form. This process involved a net volume loss of 56.6 percent. (3) Inf i l t rat ion of f luids, possibly of magmatic origin, formed epidote and garnet from scapolite, and actinolite from diopside.
Comparison of Conventional Deterministic and Entropy-Based Methods for Predicting Sediment Concentration in Debris Flow

In this study, the distribution of sediment concentration and the mean sediment concentration in debris flow were investigated using deterministic and probabilistic approaches. Tsallis entropy and Shannon entropy have recently been employed to estimate these parameters. However, other entropy theories, such as the general index entropy and Renyi entropy theories, which are generalizations of the Shannon entropy, have not been used to derive the sediment concentration in debris flow. Furthermore, no comprehensive and rigorous analysis has been conducted to compare the goodness of fit of existing conventional deterministic methods and different entropy-based methods using experimental data collected from the literature. Therefore, this study derived the analytical expressions for the distribution of sediment concentration and the mean sediment concentration in debris flow based on the general index entropy and Renyi entropy theories together with the principle of maximum entropy and tested the validity of existing conventional deterministic methods as well as four different entropy-based expressions for the limited collected observational data. This study shows the potential of using the Tsallis entropy theory together with the principle of maximum entropy to predict sediment concentration in debris flow over an erodible channel bed.
PULP AND PAPERMAKING PROPERTIES OF BAMBOO SPECIES

Pulp and paper making properties of bamboo species Melocanna baccifera were studied with a focus on the physical properties and chemical composition of bamboo chips, on pulping behavior, bleaching response, fiber morphology, refining behavior and strength properties of the bleached pulp. Melocanna baccifera species was found to have 52.8% cellulose, 21.1% hemicelluloses and 25.2% lignin, i.e. similar to hardwood. The produced pulp could be bleached to 89 ± 1% ISO brightness. The bleached pulp refined to 25 °SR had 54.6 Nm/g tensile index, 10.7 mN.m 2 /g tear index, 4.95 kN.m 2 /g burst index and 328 double folds. Also, the bleached pulp had an average fiber length of 1.68 mm, which is higher than that of hardwood pulp (0.88-1.1 mm), but lower than that of softwood pulp (2.2-3.5 mm). Meanwhile, the pulp had an average fiber width of 17.1 μm, which is similar to that of hardwood fiber (16-20 μm), but lower than that of softwood fiber (28-35 μm).
VISUALIZATION STUDY OF THERMOACOUSTIC INSTABILITIE S IN A BACKWARD-FACING STEP STABILIZED LEAN-PREMIXED FLA ME IN HIGH TURBULENCE FLOW

Low-frequency combustion instabilities were studied xperimentally in a model lean-premixed stepped combustor. The PLIF technique was used to character ize the flame structure. The PIV technique, associa ted with high-speed visualization of the OH* radical chemilu inescence’s emission, allowed to investigate the f low field during the quasi-periodic unsteady flashback when t flame lifted from the edge of the step and moved p riodically in and out of the premixing duct. Results strongly suggest that impact of acoustic waves on the flame structure should be taken into account when applying LES appr oach to industrial gas turbines.
Enumerative Geometry of Calabi-Yau 5-Folds R . Pandharipande and A . Zinger

Gromov-Witten theory is used to define an enumerative geometry of curves in Calabi-Yau 5-folds. We find recursions for meeting numbers of genus 0 curves, and we determine the contributions of moving multiple covers of genus 0 curves to the genus 1 Gromov-Witten invariants. The resulting invariants, conjectured to be integral, are analogous to the previously defined BPS counts for Calabi-Yau 3 and 4-folds. We comment on the situation in higher dimensions where new issues arise. Two main examples are considered: the local Calabi-Yau P with normal bundle ⊕i=1O(−1) and the compact Calabi-Yau hypersurface X7 ⊂ P. In the former case, a closed form for our integer invariants has been conjectured by G. Martin. In the latter case, we recover in low degrees the classical enumeration of elliptic curves by Ellingsrud and Strömme.
Fiscal policy and economic growth in the West African Economic Monetary Union Countries Chabossou

Since the early 1990s, the West African Economic Monetary Union (WAEMU) countries have introduced tax reforms to reduce distortions in the common market and therefore to be strengthening revenue mobilization to support growth. The purpose of this article is to show that such a tax policy, designed as the use made of tax for economic or social purposes, promotes economic growth in the area. I establish this by building on the econometrics of panel data, including the period from 1980 to 2014.
L’impact de l’Implémentation des ERP sur la Performance de la Gestion de la Chaîne Logistique : Étude de Cas d’un Groupe Agricole Marocain

With the digitization of the economy, number of disciplines have witnesses significant evolution, including Enterprise Resource Planning systems and Supply Chain Management. However, prior research mainly focuses on the question of ERP and/or SCM in industrial firms. Therefore, this paper aims to explore the research field linking ERP systems and SCM performance in the agricultural sector, as to answer the following research problem: to what extent does ERP’s implementation affect the performance of SCM within farm businesses? Taking the Moroccan context into account, the importance of studying the case of farm businesses is highlighted. They play a significant role in the revival of the Moroccan economy, despite the various complications to which they are confronted. The article consists of a case study research and presents results from 10 semi-structured interviews carried out within a Moroccan farm group, which implemented an ERP system back in 2018. The variation of SCM performance indicators was analyzed three years post go-live. Findings from this study show that ERP’s implementation has a positive impact on the farm group’s supply chain management. In fact, the examined supply chain metrics: customer service (CS), financial perspective (FP), innovation & learning (IL), internal business (IB) and supplier performance (SP), all achieved medium performance improvement by 2020. Considering the small sample size as well as non-existent literature findings, further research should extend the sample set.
The Role of Discourse, Text and Practice in the Construction of Organizational Reality

Functional approaches and practices can be seen as loci of knowledge production and preservation. The present paper provides a comprehensive reflection on the former by discussing in detail the concept of discourse and discourse analysis applied to organisational contexts. Indeed, language and discourse are the principal means by which institutions and organisations create their own social reality. With the aim to clarifying how the social world is constructed and construed through actions of intersubjective meaning-making processes and to avoid the emphasis placed only on micro-linguistic elements, Critical Discourse Analysis (CDA) was introduced to raise the attention on the macro-social aspects of discourse within organisations. role in being social mediators for change, which may be somehow contraposed to the natural selection view of organisations, in which only those who adapt themselves to the environment may hopefully survive. The theoretical foundation of discourse supports automatic text analysis in filling the gap between techniques in the calculation and the conceptual reflection concerning the role of discourse in organisations, and widely within society 1 . As suggested by Fairclough in his original idea about the structure of discourse, several elements, such as text (at a micro-level), practices (at a meso-level), and discourse (at a macro-level) contribute in supplying to researcher a weave to interpret texts that contribute to producing and reproducing social contexts.
Fast Spiking of a Mott VO2-Carbon Nanotube Composite Device.

The recent surge of interest in brain-inspired computing and power-efficient electronics has dramatically bolstered development of computation and communication using neuron-like spiking signals. Devices that can produce rapid and energy-efficient spiking could significantly advance these applications. Here we demonstrate DC-current or voltage-driven periodic spiking with sub-20 ns pulse widths from a single device composed of a thin VO2 film with a metallic carbon nanotube as a nanoscale heater, without using an external capacitor. Compared with VO2-only devices, adding the nanotube heater dramatically decreases the transient duration and pulse energy, and increases the spiking frequency, by up to three orders of magnitude. This is caused by heating and cooling of the VO2 across its insulator-metal transition being localized to a nanoscale conduction channel in an otherwise bulk medium. This result provides an important component of energy-efficient neuromorphic computing systems, and a lithography-free technique for energy-scaling of electronic devices that operate via bulk mechanisms.
Positive solutions of nonlinear second order ordinary differential equations

We prove an existence theorem for positive solutions of nonlinear second order ordinary differential equations by using the perturbation method and the Schauder fixed point theorem.

Archeological ceramic artifacts characterization through computed microtomography and <fc>X</fc>â•’ray fluorescence

The analysis of ceramicmaterials has been proven to be an indispensable tool for indirectly approaching past people and societies through their cultural remnants, allowing inferences about their technology, and their interactionwith their surrounding physical and social environments. Pottery products acquire their characteristic properties during the manufacture process. Compositional (mineralogical and chemical) and microstructural analyses have become an integral part of interdisciplinary archaeological research, underlining the importance of compositional and technological comparative studies. As damages must be avoided to the archeological artifacts under study, nondestructivity is an essential requirement for the scientific methods operating in this research field. Therefore, the aim of this publication is to correlate 2 nondestructive techniques, namely, computed microtomography and X-ray microfluorescence in the structural characterization and investigation of the elemental composition of ceramic samples from 2 different Brazilian archaeological sites. Computed microtomography allowed to differentiate the various materials with different densities that compose the samples. These materials had their elemental composition revealed by X-ray microfluorescence technique, where several tempers used during the manufacturing process were identified.

DNA as a Supramolecular Scaffold

Since the elucidation of the structure of DNA in 1953, a revolution has occurred in molecular biology that recently culminated in the sequencing of the entire human genome. However, the properties that define DNA as a macromolecule with the most essential role in biology are also of tremendous importance in the design and understanding of DNA as a structural component in nanotechnology. After all, it could be argued that DNA is the ultimate supramolecular architecture. In this article, we describe the structural features of DNA that allow application as what promises to be one of the most fundamental supramolecular scaffolds. In describing this, we discuss the importance of molecular recognition and DNA binding in the design of synthetic DNA architectures, diagnostic agents, and the growth of new DNA-hybrid materials. The understanding of how DNA acts as a template, both to allow its own replication and to assemble cations, is also vital, as is an appreciation of topological concepts in the design of new materials. Finally, we describe how these ideas were applied to the design of DNA-based architectures for nanolithography, DNA machines, molecular wires, and as chiral memory devices.
Augmenting Tactile 3D Data Navigation With Pressure Sensing

We present a pressure‐augmented tactile 3D data navigation technique, specifically designed for small devices, motivated by the need to support the interactive visualization beyond traditional workstations. While touch input has been studied extensively on large screens, current techniques do not scale to small and portable devices. We use phone‐based pressure sensing with a binary mapping to separate interaction degrees of freedom (DOF) and thus allow users to easily select different manipulation schemes (e. g., users first perform only rotation and then with a simple pressure input to switch to translation). We compare our technique to traditional 3D‐RST (rotation, scaling, translation) using a docking task in a controlled experiment. The results show that our technique increases the accuracy of interaction, with limited impact on speed. We discuss the implications for 3D interaction design and verify that our results extend to older devices with pseudo pressure and are valid in realistic phone usage scenarios.
Dynamic response-based LEDs health and temperature monitoring

Previous experiments of water vapor penetration into polyelectrolyte membrane (PEM) thin films have indicated the influence of the water concentration gradient and polymer chemistry on the interface evolution, which will eventually affect the efficiency of the fuel cell operation. Moreover, PEMs of different side chains have shown differences in water cluster structure and diffusion. The evolution of the interface between water and polyelectrolyte membranes (PEMs), which are used in fuel cells and flow batteries, of three different side-chain lengths has been studied using dissipative particle dynamics (DPD) simulations. Higher and faster water uptake is usually beneficial in the operation of fuel cells and flow batteries. The simulated water uptake increased with the increasing side chain length. In addition, the water uptake was rapid initially and slowed down afterwards, which is in agreement with the experimental observations. The water cluster formation rate was also found to increase with the increasing side-chain length, whereas the water cluster shapes were unaffected. Water diffusion in the membranes, which affects proton mobility in the PEMs, increased with the side-chain length at all distances from the interface. In conclusion, side-chain length was found to have a strong influence on the interface water structure and water penetration rates, which can be harnessed for the better design of PEMs. Since the PEM can undergo cycles of dehydration and rehydration, faster water uptake increases the efficiency of these devices. We show that the longer side chains with backbone structure similar to Nafion should be more suitable for fuel cell/flow battery usage.
