Fluorescent Molecular Probes II. The Synthesis, Spectral Properties and Use of Fluorescent Solvatochromic Dapoxyl Dyes

Abstract— 2,5‐Diphenyloxazoles that embody a dimethylamino group at position 4 of the 5‐phenyl ring and a sulfonyl group at position 4 of the 2‐phenyl ring were prepared as new fluorescent solvatochromic dyes. In these molecules, there is a “push‐pull” electron transfer system from the 5‐phenyl moiety to the 2‐phenyl ring. These compounds show strong solvent‐dependent fluorescence that is well correlated with the empirical solvent polarity parameter ET (30). The solvent polarity dependence suggests that the fluorescence arises from an intramolecular charge transfer. The fluorescence‐environment dependence, long emission wavelength, large extinction coefficients, high fluorescence quantum yields and large Stokes shift of the fluorophores can be used to develop ultrasensitive fluorescent molecular probes to study a variety of biological events and processes.
Radiolytic synthesis of ? OH group functionalized fullerene structures and their biosensor application

In this study, radiolytic functionalization of fullerene in methanol/1,2-dichlorobenzene mixtures and its applications with respect to biosensor support materials were studied. To obtain supports for biosensors for electron transfer, fullerene was functionalized by γ-irradiation in a methanol/1,2-dichlorobenzene mixture solution. The hydroxyl group-modified fullerene, F-fullerene, was characterized by Fourier-transform infrared, Raman spectroscopy, MALDI-TOF mass spectroscopy, and elemental analysis. As a result, the main hydroxyl group was successfully introduced on the surface of fullerene. F-fullerene was found to disperse well in water by ultrasonication. The results indicated that F-fullerene is a good candidate for use in biological systems as a biosensor support material. A biosensor based on F-fullerene was prepared by hand-casting the mixture of tyrosinase, F-fullerene, and 2% chitosan solution on an ITO electrode. Furthermore, the prepared biosensor was optimized pH and temperature. The prepared biosensor was then evaluated for its ability to analyze phenolic compounds contained in commercial red wines. The total phenolic concentration was determined to be in the range of 397–895 mg/L. From these results, the electron transfer ability of F-fullerene was improved on an enzyme biosensor. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Incidence of an Ozonation Stage on the Treatment of Cherry Stillage by Activated Sludge

ABSTRACT This article presents a laboratory study of the ozonation of diluted cherry stillage, a high-strength wastewater. Influence of variables, kinetics, and the effects of an ozonation stage coupled with the biological treatment by activated sludge are addressed. Single activated sludge processing was shown effective to remove biological oxygen demand (BOD) and chemical oxygen demand (COD) but polyphenols were reduced to a lesser extent. On the other hand, direct wastewater ozonation did not reduce COD and total organic carbon (TOC) appreciably, and foaming problems were experienced when a high gas flow rate was applied. However, polyphenols and UV254 absorbance decreased substantially by means of ozonation. To best achieve complete cherry stillage purification, two ways of coupling ozonation with activated sludge are proposed. Ozonation prior to activated sludge is advised for high-concentration wastewater to reduce polyphenol concentration, thus removing inhibiting effects. For wastewater with low polyphenol concentration the sequence activated sludge–ozonation–activated sludge is preferred to enhance the overall process performance in terms of oxidation efficiency and sludge settling.
Scales of Nucleophilicity and Electrophilicity: A System for Ordering Polar Organic and Organometallic Reactions

Contrary to widely held opinion, for many reactions in organic and organometallic chemistry it is possible to define nucleophilicity and electrophilicity parameters that are independent of the reaction partners. This phenomenon, discovered by Ritchie during the early 1970s for reactions of highly stabilized carbenium and diazonium ions with n-nucleophiles, also occurs with reactions of carbenium ions with aliphatic and aromatic π-electron systems and in hydride transfer reactions. With the aid of the scales of nucleophilicity and electrophilicity set out here, which extend over eighteen orders of magnitude, forecasts can be made about the feasibility and rate of a given CC bond formation, ionic reduction, or diazo coupling. Linkage with the reactivity scales of Ritchie and Sweigart/Kane-Maguire enables a unified treatment of a large number of polar reactions.
Method development and validation of an HPLC assay for the detection of hopantenic acid in human plasma and its application to a pharmacokinetic study on volunteers

Summary A reliable and sensitive reversed-phase high performance liquid chromatography (RP-HPLC) with ultraviolet (UV) detection method was developed and validated for the quantification of hopantenic acid in human plasma. Hopantenic acid, with protocatechuic acid as the internal standard (IS), was extracted from plasma samples using a liquid-liquid extraction with methanol. A chromatographic separation was achieved on a Luna C18 column (4.6 mm × 150 mm, 5-μm particle size) and precolumn of the same sorbent (2.0 mm). An isocratic elution, at a flow rate of 1.0 mL min−1, was used with a mobile phase consisting of acetonitrile, water, and 0.03% trifluoroacetic acid. The UV detector was set to 205 nm. The elution times for hopantenic acid and IS were ∼4.3 and 5.4 min, respectively. The calibration curve of hopantenic acid was linear (r > 0.9994) over the range of 0.5–100 μg mL−1 in human plasma. The limit of detection and limit of quantification for hopantenic acid were 0.034 and 0.103 μg mL−1, respectively.
THE EFFECT OF THICKENER ON THE RHEOLOGY OF COATING COLORS

The effect of type and amount of thickener on the shear and extensional rheological properties of paper coating colors was studied. A coarse delaminated kaolin clay was used as pigment and either a carboxy methylcellulose (CMC) or an associative gum was used as thickener. The shear properties were evaluated with a stress controlled rheometer and the extensional properties were obtained at high strain rates using an orifice flow meter. The apparent extensional viscosity was compared to the shear viscosity in terms of the Trouton ratio, which was shown to exceed considerably the theoretical value of 3 expected for Newtonian fluids. Suspensions formulated with the associative gum exhibited more pronounced strain hardening at high strain rates than those prepared with CMC.
Superconductivity of alkali metal intercalated TiNBr with α-type nitride layers

TiNBr with α-type nitride layers (isostructural with FeOCl) was electron-doped by the intercalation of alkali metal (Li, Na, K, and Rb), which can be cointercalated with organic solvent molecules such as tetrahydrofuran (THF) and propylene carbonate (PC), expanding the basal spacing (d) up to 16 Å. All of the alkali metal intercalation compounds with and without cointercalation become superconductors with transition temperatures (Tc) up to 17.2 K. The Tc varies in a narrow temperature range against a wide range change of 0.1 < x < 0.46 in AxTiNBr. The Tc decreases linearly with the decreasing value of 1/d. The layer structured superconductors show a low anisotropy on the upper critical field (Hc2). These are characteristic features very similar to those found for the intercalation compounds of the Cl homolog TiNCl.
Novel nanoscale thermal property imaging technique: The 2ω method. II. Demonstration and comparison

This paper presents the 2ω method, a newly developed ac mode local thermal property imaging technique with nanoscale spatial resolution. The authors batch-fabricate the thermoelectric probe, whose junction size is about 200nm, with yield higher than 95%. The shortest time constant of the thermoelectric probe is measured to be 0.72ms. They experimentally demonstrate that the 2ω method can map out the local thermal property of a sample by monitoring the amplitude of the 2ω signal from the thermocouple junction of a probe heated by an ac. By comparing with the thermal property images obtained by other methods, they also show that the 2ω method using the point-heating and point-sensing scheme is the most suitable for the nanoscale thermal property imaging.
Strategies for the preparation of compounds of alkali metal anions

By using alkali cation complexing agents of the crown and cryptand classes (C) and appropriate solvents, solutions can be prepared which contain essentially only M/sup +/C and M/sup -/ in equal concentrations. From estimates of the metal solubility in the absence of the complexing agent and of the cation complexation constant, the solubility in the presence of the complexing agent can be predicted. If, in the metal solution with C absent, the e/sub solv//sup -//M/sup -/ ratio is appreciable, then when C is used and the solution is allowed to contact excess metal, this ratio will remain nearly the same. Therefore, in addition to MC/sup +/ and M/sup -/, the solution may contain relatively high concentrations of e/solv//sup -/. Examples of the application of these equilibrium considerations to various metal-solvent combinations are described. Only Na/sup +/C.Na/sup -/, in which C is 2,2,2 cryptand was prepared as a crystalline solid. Gold-colored solid films were obtained by rapid evaporation of solutions of Na, K, Rb, and Cs in one or more of the solvents methylamine (MA), ethylamine (EA), and tetrahydrofuran (THF) when the complexing agent 2,2,2 cryptand is present. In addition, gold-colored films are obtained with Na and K when 18-crown-6 ismore » used. The former metal gives the film when MA is the solvent while the latter gives it with THF. In these cases, the gold film apparently yields the metal plus 18-crown-6 when the solvent vapors are removed. The criteria for thermodynamic vs. kinetic stability of salts of M/sup -/ are considered. (auth)« less
Chemical Modification of Wood by Polyglycerol/Maleic Anhydride Treatment

Summary Polyglycerol (PG), an agricultural by-product of diester industry, was reacted with maleic anhydride (MA) to give heat curable compounds which are useful for impregnating wood to improve biological resistance, dimensional stability and strength. The relationships between reaction conditions of polyglycerol/maleic anhydride (PG/MA) adduct treatment and performance of treated solid wood were investigated. Conditions recommended for producing PG/MA treated wood durable for a long time are vacuum/pressure impregnation of aqueous solutions of PG/MA adduct (30%) in the presence of 2-butanone peroxide (2%) and cobalt naphthenate (2%).
Combustibles, fuels and their combustion products: A view through carbon isotopes

Stable (i.e. non-radioactive) carbon-isotope composition (δ13C) in fuels has been extensively used as an indicator of the processes leading to the generation of their parent crude-oil. With the example of those used in Paris (France), this preliminary study isotopically characterizes fuels and combustibles, as well as the isotopic relations existing with their combustion by-products, i.e. gases (CO2) and particles (bulk carbon). Results show that δ13C in fuels is clearly related to their physical state, with natural gas being strongly depleted in 13C while coal yields the highest δ13C, and liquid fuels display intermediate values. This relation is also valid for combustion gases, although δ13C values of combustion particles form a homogeneous range within which no clear distinction is observed. Combustion processes are accompanied by carbon-isotope fractionation (noted Δ13C) resulting from the combustion being incomplete. Carbon-isotope fractionation is strictly negative (Δ13C = −1.3‰) during the formation of combustion gases, but generally positive in particle formation even if values close to zero are observed. Using simple mixing equations for describing the closed system formed by fuel, CO2 and carbonaceous particles, we discuss the carbon budget for spark-ignition (unleaded gasoline) and diesel engines. Stable carbon isotopes corroborate the already-proved superior efficiency of diesel combustion mode compared with spark ignition, as carbon is preferentially transformed into CO2.

--------------------------------------------------------------------------- Abstract: - In this paper we discuss about the Autonomous car supported machine learning using raspberry pi. Machine learning may be a sort of AI (Artificial intelligence) that gives computers with the power to find out without being explicitly programmed. Using this idea of machine learning, a car is often automated (self-driving). We train the car with specific images and whenever it detects the trained images, it operates consistent with the trained instruction. The microcontroller utilized in the car is raspberry pi which is employed to regulate the L298 driver, ultrasonic sensor and the raspberry pi camera. We use different components like pi camera which is used to train and detect the objects, L298 driver which operates the dc motor and the ultrasonic sensor to calculate the distance. This autonomous car is the prototype to the self-driving cars which is present growing advanced technology in the present scenario. This Autonomous can also use in industries for transport of goods.

Cryptojacking Detection with CPU Usage Metrics

Cryptojacking is currently being exploited by cyber-criminals. This form of malware runs in the computers of victims without their consent. It often infects browsers and does CPU-intensive computations to mine cryptocurrencies on behalf of the cyber-criminal, which takes the profits without paying for the resources consumed. Such attacks degrade computer performance and potentially reduce the hardware lifetime. We introduce a new cryptojacking detection mechanism based on monitoring the CPU usage of the visited web pages. This may look like an unreliable way to detect mining malware since many web sites are heavy computationally and that malware often throttles CPU usage. However, by combining a set of CPU monitoring features and using machine learning, we manage to obtain metrics like precision and recall close to 1.

FORMATION OF ARABIDOPSIS POLY(A)-SPECIFIC RIBONUCLEASE ASSOCIATED PROCESSING BODIES IN RESPONSE TO PATHOGENIC INFECTION

In eukaryotes, the fate of messenger RNA (mRNA) is tightly regulated. Identifying the role of specific regulatory proteins involved in post-transcriptional gene regulation is highly intriguing. Specific cytoplasmic foci known as the processing bodies (P-bodies) play a critical role, as it harbours numerous protein complexes which are involved in degradation and translational arrest of mRNA. Essentially, the protein components present in P-bodies are primarily involved in mRNA decapping, deadenylation and decay processes. Among several ribonucleases involved in modification of the mRNA, poly(A)-specific ribonuclease (PARN) specifically facilitates the deadenylation of mRNA. Deadenylation is considered to be one of the critical events which ensure the fidelity of mRNA. The physiological role of PARN during biotic stress is not yet fully revealed. Here we report that under pathogen challenged conditions, PARN relocalizes to the cytoplasm and the number of P-bodies induced by the PARN is significantly reduced. This identifies that the molecular functioning of PARN is affected when plants are exposed to pathogens and may be well involved in contributing for plant defense.
A Dynamic Reliability Management Framework for Dark Silicon

—In this paper, we introduce the dynamic reliability management (DRM) framework for dark silicon, which is considered in one of the emerging computing platforms for the future many-core systems due to the diminishing of Dennard’s scaling. We focus on the electromigration-induced reliability problem as it is the dominant failure effect for on-chip interconnects. To make our framework more realistic, our approach is based on newly proposed physics-based electromigration (EM) reliability model, interval core-based microarchitecture model, and X86-based power model. We also apply HotSpot thermal model for the temperature estimation. We consider thermal design power (TDP) as the power constraint for a dark silicon chip. For DRM, we use the recently proposed resource-based reliability model in which each core of dark silicon chip can spend the time-to-failure (TTF) resources at different rates speciﬁed by the temperature and its power consumption. We employ both dynamic voltage and frequency scaling (DVFS) and task migration as the control knobs. A large class of multithreaded applications is used as the benchmark to validate our reliability-aware dark silicon framework and the proposed DRM method. Experimental results on a 64-core dark silicon chip show that the DRM on the proposed framework can effectively manage and optimize the lifetime of the chips under the given power budget on a dark silicon chip.
SALT TOLERANT BACTERIA FOR CROP IMPROVEMENT IN SALINE AGRICULTURE FIELDS: DEVELOPMENT, CHALLENGES AND OPPORTUNITIES

Saline stress has been the one of the biggest hurdles in achieving the demand and supply ratio of global population. To combat the growing problem of soil salinity, advanced soil management and irrigation technology are used. However, they are cost and energy intensive. Plant growth promoting rhizobacteria (PGPR) attained from saline soils can overcome the detrimental effects of salt stress on plants. PGPR positively impact physiological functions of plants such as growth, yield and overcome disease resistance. The complex and dynamic interface between microorganisms and plant roots is achieved by various mechanisms like secretion of plant growth hormones, pigments and decrease of oxidative stress. Thus, PGPR can be used as an alternative to improve yield of crops from saline lands. This review is an attempt to provide the current status on the PGPR from salt inflicted soils and their application for growing crops in saline soils.
