    A study has been made of optical aspects of airport control towers as part of a planned general optimization of control towers by Transport Canada. Problems found were reflections, glare, visual obstructions, identification of distant objects, and excessive solar heat. The study makes recommendations on cab shape, tower height, glazing, shades, sunglasses, binoculars, and internal lighting. Proper choice of cab shape (e.g., 30 degrees window inclination and 12-28 sides) provided effective control of reflections. Some plastic shades werefound to increase the risk of eye damage. Two tower cabs incorporating the recommendations have been built and were found to be satisfactory. PMID:20216882

  5. The cabABC Operon Essential for Biofilm and Rugose Colony Development in Vibrio vulnificus.

    Full Text Available A transcriptome analysis identified Vibrio vulnificus cabABC genes which were preferentially expressed in biofilms. The cabABC genes were transcribed as a single operon. The cabA gene was induced by elevated 3',5'-cyclic diguanylic acid (c-di-GMP and encoded a calcium-binding protein CabA. Comparison of the biofilms produced by the cabA mutant and its parent strain JN111 in microtiter plates using crystal-violet staining demonstrated that CabA contributed to biofilm formation in a calcium-dependent manner under elevated c-di-GMP conditions. Genetic and biochemical analyses revealed that CabA was secreted to the cell exterior through functional CabB and CabC, distributed throughout the biofilm matrix, and produced as the biofilm matured. These results, together with the observation that CabA also contributes to the development of rugose colony morphology, indicated that CabA is a matrix-associated protein required for maturation, rather than adhesion involved in the initial attachment, of biofilms. Microscopic comparison of the structure of biofilms produced by JN111 and the cabA mutant demonstrated that CabA is an extracellular matrix component essential for the development of the mature biofilm structures in flow cells and on oyster shells. Exogenously providing purified CabA restored the biofilm- and rugose colony-forming abilities of the cabA mutant when calcium was available. Circular dichroism and size exclusion analyses revealed that calcium binding induces CabA conformational changes which may lead to multimerization. Extracellular complementation experiments revealed that CabA can assemble a functional matrix only when exopolysaccharides coexist. Consequently, the combined results suggested that CabA is a structural protein of the extracellular matrix and multimerizes to a conformation functional in building robust biofilms, which may render V. vulnificus to survive in hostile environments and reach a concentrated infective dose.

  6. Active Noise Control of the Heavy Truck Interior Cab

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    In order to control the noise of the heavy truck interior cab effectively, the active noise control methods are employed. First, an interior noise field test for the heavy truck is performed, and frequencies of interior noise of this vehicle are analyzed. According to the spectrum analysis of acquired noise signal, it is found out that the main frequencies of interior noise are less than 800Hz. Then the least squares lattice (LSL) algorithm is used as signal processing algorithm of the controller and a closed-loop control DSP system, based on TMS 320VC5416, is developed. The residual signal at driver's ear is used as feedback signal. Lastly, the developed ANC system is loaded into the heavy truck cab, and controlling the noise at driver's ear for that truck at different driving speeds is attempted. The noise control test results indicate that the cab interior noise is reduced averagely by 0.9 dBA at different driving speeds.

    2015-12-04

    The Consortium for Algal Biofuel Commercialization (CAB-Comm) was established in 2010 to conduct research to enable commercial viability of alternative liquid fuels produced from algal biomass. The main objective of CAB-Comm was to dramatically improve the viability of algae as a source of liquid fuels to meet US energy needs, by addressing several significant barriers to economic viability. To achieve this goal, CAB-Comm took a diverse set of approaches on three key aspects of the algal biofuels value chain: crop protection; nutrient utilization and recycling; and the development of genetic tools. These projects have been undertaken as collaboration between six academic institutions and two industrial partners: University of California, San Diego; Scripps Institution of Oceanography; University of Nebraska, Lincoln; Rutgers University; University of California, Davis; Johns Hopkins University; Sapphire Energy; and Life Technologies.

    Previously, we have identified a calcium-binding protein that is specifically expressed in spermatids and localized to the flagella of the mature sperm in mouse, so-called mCABS1. However, the physiological roles of CABS1 in the male reproductive system have not been fully elucidated yet. In the current study, we aimed to localize and clarify the role of CABS1 in porcine (pCABS1). We determined for the first time the full nucleotides sequence of pCABS1 mRNA. pCABS1 protein was detected on SDS-PAGE gel as two bands at 75 kDa and 70 kDa in adult porcine testis, whereas one band at 70 kDa in epididymal sperm. pCABS1 immunoreactivity in seminiferous tubules was detected in the elongated spermatids, and that in the epididymal sperm was found in the acrosome as well as flagellum. The immunoreactivity of pCABS1 in the acrosomai region disappeared during acrosome reaction. We also identified that pCABS1 has a transmembrane domain using computational prediction of the amino acids sequence. The treatment of porcine capacitated sperm with anti-pCABS1 antiserum significantly decreased acrosome reactions. These results suggest that pCABS1 plays an important role in controlling calcium ion signaling during the acrosome reaction. PMID:26960363

    Workspace characteristics affect the perceived comfort level of the operator and uncomfortable working conditions have been found to have a negative impact on productivity and safety. The comfort of the operator is increasingly recognized by manufacturers as a product's added value. Comfort can positively distinguish a product and increase its competitiveness. The concept of comfort is controversial, and a clear operational definition is missing. Nevertheless, it is widely accepted that comfort is a subjective phenomenon that can be evaluated by the final users. In this study, comfort aspects of the tractor workspace interior (i.e., the cab) were investigated. Users with various levels of expertise and two medium-power utility tractors of different brands were used in a 2 x 2 mixed-factorial experimental design. Participants were involved in a dynamic assessment of the cabs, and their opinions about the different workspaces were collected through a questionnaire. Additionally, objective measurements were taken on both tractors, and subjective data were compared with objective data. Results indicate significant differences in terms of the ease of locating and operating the controls (i.e., rear-mounted three-point linkage, hydraulic system, and power take-off), the ease of starting the tractor, the ease exiting the cab, the required level of concentration in executing the tasks, the adequacy of lateral visibility from the driving station, and the level of noise at the operator's position. This article provides guidance for improving the comfort of tractor workspace interiors. Agricultural machinery manufactures would benefit from research results, differentiating themselves from competitors. PMID:23600166

    2002-01-01

    Aerosol instrumentation was used to evaluate air infiltration into tractor cabs that are used to protect the agricultural worker during pesticide applications. Preliminary surveys were conducted on three different manufactured agriculture enclosures. The results of these preliminary surveys indicated that aerosols are entering the cab through leak sources or are being generated inside the cab. These results identified the need for in-depth field evaluations of tractor cabs to identify any leak sources. To evaluate the ability of tractor cabs to reduce operator air contaminant exposure, field evaluations were conducted on two tractor cabs. Specifically, we evaluated: 1) the particle size distribution and the effectiveness of the filter system; and 2) air infiltration into the cab. These evaluations were also conducted to demonstrate the ease and practicality of using optical particle counters to evaluate the ability of cabin filtration systems. Pesticide particle size distribution during an air blast spray operation was also evaluated during the study. The field tests were conducted on a John Deere 7000 series tractor cab (tractor manufacturer's cab) and a Nelson spraycab (retrofit cab). Both cabs were equipped with high efficiency particulate air (HEPA) filter media which were assumed to be 99.97 percent efficient at removing the test aerosol, atmospheric condensation nuclei. Thus, the major source of aerosols inside the cab was assumed to be leakage around filters at the seals. Using a portable dust monitor (PDM), the ratio of the outside to inside aerosol measurements was used to calculate a cab protection factor. During the evaluations, one PDM was placed inside the tractor cab (near the tractor operator) and one PDM was placed outside (near the air intake) to count particles. During the evaluations, the instruments were switched to prevent instrument bias from affecting the findings. The ratio of the two measurements (i.e., protection factor = outside

    Kutchan, Toni M. [Donald Danforth Plant Science Center, St. Louis, MO (United States)

    2015-12-02

    One of the great challenges facing current and future generations is how to meet growing energy demands in an environmentally sustainable manner. Renewable energy sources, including wind, geothermal, solar, hydroelectric, and biofuel energy systems, are rapidly being developed as sustainable alternatives to fossil fuels. Biofuels are particularly attractive to the U.S., given its vast agricultural resources. The first generation of biofuel systems was based on fermentation of sugars to produce ethanol, typically from food crops. Subsequent generations of biofuel systems, including those included in the CABS project, will build upon the experiences learned from those early research results and will have improved production efficiencies, reduced environmental impacts and decreased reliance on food crops. Thermodynamic models predict that the next generations of biofuel systems will yield three- to five-fold more recoverable energy products. To address the technological challenges necessary to develop enhanced biofuel systems, greater understanding of the non-equilibrium processes involved in solar energy conversion and the channeling of reduced carbon into biofuel products must be developed. The objective of the proposed Center for Advanced Biofuel Systems (CABS) was to increase the thermodynamic and kinetic efficiency of select plant- and algal-based fuel production systems using rational metabolic engineering approaches grounded in modern systems biology. The overall strategy was to increase the efficiency of solar energy conversion into oils and other specialty biofuel components by channeling metabolic flux toward products using advanced catalysts and sensible design:1) employing novel protein catalysts that increase the thermodynamic and kinetic efficiencies of photosynthesis and oil biosynthesis; 2) engineering metabolic networks to enhance acetyl-CoA production and its channeling towards lipid synthesis; and 3) engineering new metabolic networks for the

    Full Text Available An experimental investigation and performance analysis of inertia properties measurement for heavy truck cab is presented. This method is specifically intended for measuring the inertia properties of irregular rigid bodies, and it has the potential to be applied to the measurement of the inertia properties of vehicle bodies, such as the cab, engine, and gearbox. This article, based on CATARC moment of inertia measurement system test rig, develops an accurate measuring method to identify inertia parameters of heavy truck cab. First, corresponding tests are carried out, and the lever principle and moments of inertia parallel theorem are employed to calculate and analyse the test results, which leads to the accurate value of inertia parameters. Second, the performance analysis of the proposed method is verified through the measurement error analysis. As a result, the proposed method shows high accuracy, which provides an experimental basis for accurate inertia parameter measurement of heavy truck cab.

    2015-12-01

    Air exchange rates (AERs) have a direct impact on traffic-related air pollutant (TRAP) levels inside vehicles. Taxi drivers are occupationally exposed to TRAP on a daily basis, yet there is limited measurement of AERs in taxi cabs. To fill this gap, AERs were quantified in 22 representative Los Angeles taxi cabs including 10 Prius, 5 Crown Victoria, 3 Camry, 3 Caravan, and 1 Uplander under realistic driving (RD) conditions. To further study the impacts of window position and ventilation settings on taxi AERs, additional tests were conducted on 14 taxis with windows closed (WC) and on the other 8 taxis with not only windows closed but also medium fan speed (WC-MFS) under outdoor air mode. Under RD conditions, the AERs in all 22 cabs had a mean of 63 h-1 with a median of 38 h-1. Similar AERs were observed under WC condition when compared to those measured under RD condition. Under WC-MFS condition, AERs were significantly increased in all taxi cabs, when compared with those measured under RD condition. A General Estimating Equation (GEE) model was developed and the modeling results showed that vehicle model was a significant factor in determining the AERs in taxi cabs under RD condition. Driving speed and car age were positively associated with AERs but not statistically significant. Overall, AERs measured in taxi cabs were much higher than typical AERs people usually encounter in indoor environments such as homes, offices, and even regular passenger vehicles.

    We compared the fatality risk for occupants of rear passenger seats in extended cab and crew cab pickup trucks to the fatality risk for front seat occupants of the same vehicles using the (US) Fatality Analysis Reporting System (FARS) for 1982-1997. A 10-digit truncated vehicle identification number was used to classify the pickup trucks. The data were analyzed with an estimating equation for data having few observations per stratum. We identified 549 extended cab pickup trucks with one or more occupants of rear passenger seats and one or more occupant deaths. Occupants of rear passenger seats had a fatality risk 43% lower than front seat occupants (95% confidence interval 32% to 52%), controlling for age, sex, and restraint use. Occupants of rear seats of extended cabs in compact pickup trucks did not experience any higher fatality risk (relative to front-seat occupants of the same vehicles) than rear seat occupants of extended cabs in full-size pickup trucks and large 4-door crew cabs.

    The California Continental Borderland`s present configuration dates from about 4 to 5 X 10{sup 6} years Before Present (B.P.) and is the most recent of several configurations of the southern California margin that have evolved after the North America Plate over-rode the East Pacific Rise about 30 X 10{sup 6} years ago. The present morphology is a series of two to three northwest-southeast trending rows of depressions separated by banks and insular ridges. Two inner basins, Santa Monica and San Pedro, have been the site for the Department of Energy-funded California Basin Study (CaBS) Santa Monica and San Pedro Basins contain post-Miocene sediment thicknesses of about 2.5 and 1.5 km respectively. During the Holocene (past 10,000 years) about 10-12 m have accumulated. The sediment entered the basin by one or a combination of processes including particle infall (mainly as bioaggregates) from surface waters, from nepheloid plumes (surface, mid-depths and near-bottom), from turbidity currents, mass movements, and to a very minor degree direct precipitation. In Santa Monica Basin, during the last century, particle infall and nepheloid plume transport have been the most common processes. The former dominates in the central basin floor in water depths from 900 to 945 m. where a characteristic silt-clay with a typical mean diameter of about 0.006 mm, phi standard deviation.

    High consumption of ethanolic beverages facilitates neurodegeneration,but the mechanism of this process still remained elusive.Suppression subtractive hybridization (SSH) is a technique for detection of rare transcripts.With SSH approach,we identified one ethanol response gene Cab45,which was down-regulated by ethanol with time-dependent manner in B104 cells.The full-length sequence of Cab45 gene was obtained by 5'-RACE (5'Rapid Amplification of cDNA Ends) for the first time in rat.Based on the sequence of deduced amino acid of rat Cab45,the alignment was conducted with its counterparts in different species and displayed a high conservation.Using different tissues in rat and cell lines,Cab45 was characterized by a ubiquitous expression and differentiation dependent down-regulation.Given that ethanol facilitates some cell differentiation,we hypothesize that Cab45 is involved in ethanol-mediated differentiation.With transient transfection,the function of Cab45 was investigated by up-regulation and down-regulation in PC12 cells.Ethanol treatment and UV exposure were conducted subsequently and cell proliferations were detected by MTT (Methyl Thiazolyl Tetrazolium) approach.It revealed that the up-regulation of Cab45 modulated the impairment elicited by ethanol and UV in transfected cells.As a member of new calcium binding protein family,the exact role of Cab45 still remains unclear.

    2015-07-01

    To investigate pmrCAB sequence divergence in 5 species of Acinetobacter baumannii complex, a total of 80 isolates from a Korean hospital were explored. We evaluated nucleotide and amino acid polymorphisms of pmrCAB operon, and phylogenetic trees were constructed for each gene of prmCAB operon. Colistin and polymyxin B susceptibility was determined for all isolates, and multilocus sequence typing was also performed for A. baumannii isolates. Our results showed that each species of A. baumannii complex has divergent pmrCAB operon sequences. We identified a distinct pmrCAB allele allied with Acinetobacter nosocomialis in gene trees. Different grouping in each gene tree suggests sporadic recombination or emergence of pmrCAB genes among Acinetobacter species. Sequence polymorphisms among Acinetobacter species might not be associated with colistin resistance. We revealed that a distinct pmrCAB allele may be widespread across the continents such as North America and Asia and that sporadic genetic recombination or emergence of pmrCAB genes might occur.

    Although regulation of translation fidelity is an essential process(1-7), diverse organisms and organelles have differing requirements of translational accuracy(8-15), and errors in gene translation serve an adaptive function under certain conditions(16-20). Therefore, optimal levels of fidelity may vary according to context. Most bacteria utilize a two-step pathway for the specific synthesis of aminoacylated glutamine and/or asparagine tRNAs, involving the glutamine amidotransferase GatCAB(21-25), but it had not been appreciated that GatCAB may play a role in modulating mistranslation rates. Here, by using a forward genetic screen, we show that the mycobacterial GatCAB enzyme complex mediates the translational fidelity of glutamine and asparagine codons. We identify mutations in gatA that cause partial loss of function in the holoenzyme, with a consequent increase in rates of mistranslation. By monitoring single-cell transcription dynamics, we demonstrate that reduced gatCAB expression leads to increased mistranslation rates, which result in enhanced rifampicin-specific phenotypic resistance. Consistent with this, strains with mutations in gatA from clinical isolates of Mycobacterium tuberculosis show increased mistranslation, with associated antibiotic tolerance, suggesting a role for mistranslation as an adaptive strategy in tuberculosis. Together, our findings demonstrate a potential role for the indirect tRNA aminoacylation pathway in regulating translational fidelity and adaptive mistranslation. PMID:27564922

    Under high pressure,the long believed single-phase material CaB6 was latterly discovered to have a new phase tI56.Based on the density-functional theory,the pressure effects on the structural and elastic properties of CaB6 are obtained.The calculated bulk,shear,and Young's moduli of the recently synthesized high pressure phase tI56-CaB6 are larger than those of the low pressure phase.Moreover,the high pressure phase of CaB6 has ductile behaviors,and its ductility increases with the increase of pressure.On the contrary,the calculated results indicate that the low pressure phase of CaB6 is brittle.The calculated Debye temperature indicates that the thermal conductivity of CaB6 is not very good.Furthermore,based on the Christoffel equation,the slowness surface of the acoustic waves is obtained.

    For the complex structure and vibration characteristics of coupling driver-seat-cab system of trucks, there is no damping optimisation theory for its suspensions at present, which seriously restricts the improvement of vehicle ride comfort. Thus, in this paper, the seat suspension was regarded as 'the fifth suspension' of cab, the 'Five-suspensions' for this system was proposed. Based on this, using the mechanism modelling method, a 4 degree-of-freedom coupling driver-seat-cab system model was presented; then, by the tested cab suspensions excitation and seat acceleration response, its parameters identification mathematical model was established. Based on this, taking optimal ride comfort as target, its damping collaborative optimisation mathematical model was built. Combining the tested signals and a simulation model with the mathematical models of parameters identification and damping collaborative optimisation, a complete flow of hybrid modelling and damping collaborative optimisation of Five-suspensions was presented. With a practical example of seat and cab system, the damping parameters were optimised and validated by simulation and bench test. The results show that the model and method proposed are correct and reliable, providing a valuable reference for the design of seat suspension and cab suspensions.

    Annual fuel use for long-haul truck rest period idling is estimated at 667 million gallons in the United States. The U.S. Department of Energy’s National Renewable Energy Laboratory’s CoolCab project aims to reduce heating, ventilating, and air conditioning (HVAC) loads and resulting fuel use from rest period idling by working closely with industry to design efficient long-haul truck climate control systems while maintaining occupant comfort. Enhancing the thermal performance of cab/sleepers will enable smaller, lighter, and more cost-effective idle reduction solutions. In order for candidate idle reduction technologies to be implemented at the original equipment manufacturer and fleet level, their effectiveness must be quantified. To address this need, a number of promising candidate technologies were evaluated through experimentation and modeling to determine their effectiveness in reducing rest period HVAC loads. For this study, load reduction strategies were grouped into the focus areas of solar envelope, occupant environment, and conductive pathways. The technologies selected for a complete-cab package of technologies were “ultra-white” paint, advanced insulation, and advanced curtains. To measure the impact of these technologies, a nationally-averaged solar-weighted reflectivity long-haul truck paint color was determined and applied to the baseline test vehicle. Using the complete-cab package of technologies, electrical energy consumption for long-haul truck daytime rest period air conditioning was reduced by at least 35% for summer weather conditions in Colorado. The National Renewable Energy Laboratory's CoolCalc model was then used to extrapolate the performance of the thermal load reduction technologies nationally for 161 major U.S. cities using typical weather conditions for each location over an entire year.

    Improved human-tractor interface designs, such as well-accommodated operator enclosures (i.e. cabs and protection frames) can enhance operator productivity, comfort and safety. This study investigated farm-worker anthropometry and determined the critical anthropometric measures and 3-D feature envelopes of body landmarks for the design of tractor operator enclosures. One hundred agriculture workers participated in the study. Their body size and shape information was registered, using a 3-D full-body laser scanner. Knee height (sitting) and another eight parameters were found to affect the cab-enclosure accommodation rating and multiple anthropometric dimensions interactively affected the steering wheel and gear-handle impediment. A principal component analysis has identified 15 representative human body models for digitally assessing tractor-cab accommodation. A set of centroid coordinates of 34 body landmarks and the 95% confidence semi-axis-length for each landmark location were developed to guide tractor designers in their placement of tractor control components in order to best accommodate the user population. Finally, the vertical clearance (90 cm) for agriculture tractor enclosure in the current SAE International J2194 standard appeared to be too short as compared to the 99th percentile sitting height of male farm workers in this study (100.6 cm) and in the 1994 National Health and Nutrition Examination Survey III database (99.9 cm) and of the male civilian population in the 2002 Civilian American and European Surface Anthropometric Resource database (100.4 cm).

    Cellulose acetate butyrate (CAB) and cellulose acetate propionate (CAP) were prepared homogeneously in a 1-allyl-3-methylimidazolium chloride (AmimCl) ionic liquid system from sugarcane bagasse (SB). The reaction temperature, reaction time, and molar ratio of butyric (propionic) anhydride/anhydroglucose units in the cellulose affect the butyryl (B) or propionyl (P) content of CAB or CAP samples. The (13)C NMR data revealed the distribution of the substituents of CAB and CAP. The thermal stability of sugar cane bagasse cellulose was found by thermogravimetric analysis to have decreased after chemical modification. After reaction, the ionic liquid was effectively recycled and reused. This study provides a new way for high-value-added utilization of SB and realizing the objective of turning waste into wealth.

    Ergonomically designed driver's cabs also contribute directly to the increase in safety at work. In the course of the electrical re-design of the open-cast mining machines new drivers' cabs, which eliminate ergonomic deficits, were used. Other important aspects in addition to the improvements in the environmental factors noise, vibration and dust, are in particular the visibility conditions, visualisation of process data and monitoring as well as operating concepts. Taking into account the different types of machine drivers' cabs with a modified basic design and bearing design are used. Optimisation of the installation of the monitors and the basic structuring of the control panels was carried out. In addition to the increase in the effectiveness of control another aim is to minimise faulty operation by the driver when changing machines frequently. (orig.)

  3. Low-temperature thermal conductivity of CaB6 and EuB6

    International Nuclear Information System (INIS)

    The thermal conductivities of stoichiometric CaB6, vacancy-doped Ca1-δB6, and EuB6 have been measured between 6 and 300 K. All our data may be rather well described across the entire temperature regime covered on the basis of a Debye-type relaxation-time approximation and by assuming the concurring influence of various scattering channels on the mean free path of the phonons. An unusual and strong resonance in the scattering rate of the phonons of all investigated materials is attributed to a strong interaction between acoustic itinerant and localized modes, the latter arising from oscillations of the metal cations around their equilibrium position

  4. Challenges of establishing a Community Advisory Board (CAB in a low-income, low-resource setting: experiences from Bagamoyo, Tanzania

    Full Text Available Abstract Objective Community Advisory Boards are now seen as standard practice for clinical vaccine and drug trials worldwide. In the past, most Community Advisory Boards (CABs were established by activists and lobbyists to monitor HIV/AIDS vaccine and drug trials in developed countries. In Africa the first CAB was established in Uganda in 1990 in conjunction with an HIV vaccine project and has since been followed by others in South Africa, Zimbabwe, and Kenya. In 2007, the Bagamoyo branch of the Ifakara Health Institute initiated the formation of a CAB. The aim was to properly educate and empower elected CAB members to become full partners in all research activities concerning the public within the Bagamoyo area. Methods and Results Beginning in 2007, staff visited each of the 24 villages within the study area to inform the communities about the proposed CAB and asked them to elect two individuals to represent their village on the CAB. The first attempt was hampered by community leaders selecting themselves, which led to inconsistent attendance, gender imbalance, and political infighting. New criteria for the selection of representatives were implemented to exclude governmental leaders, illiterate representatives and to promote a one-to-one gender balance. The newly appointed representatives underwent training and have participated in CAB meetings largely devoid of the negative issues previously encountered. Conclusion The successfully established CAB has led to improved relations with the community and facilitated the recruitment of study subjects. Our experiences show that, it is possible to establish a non-specific CAB in a low-income setting.

    Full Text Available Formation of Ag nanoparticles (NPs in the near-surface layer of CaB4O7–Ag2O and CaB4O7 –Gd2O3–Ag2O glasses by annealing in vacuum or in air is reported. It is concluded that annealing in vacuum does not necessary require the presence of reducing ions. Intensive plasmon absorption bands peaked at 403, 406 and 413.3 nm were observed in the absorption spectra of glasses with Ag NPs. Average radius of nanoparticles was calculated from the plasmon band half width and falls within 1.3-3.3 nm. It is concluded that calculated from normalized transmission spectra and absorption spectra the non-linear refractive index n2 increases due to the plasmon resonance in Ag NPs.

  9. Optimization of a neutron transmission beamline applied to materials science for the CAB linear accelerator

    International Nuclear Information System (INIS)

    The Neutrons and Reactors Laboratory (NYR) of CAB (Centro Atomico Bariloche) is equipped with a linear electron accelerator (LINAC - Linear particle accelerator). This LINAC is used as a neutron source from which two beams are extracted to perform neutron transmission and dispersion experiments. Through these experiments, structural and dynamic properties of materials can be studied. The neutron transmission experiments consist in a collimated neutron beam which interacts with a sample and a detector behind the sample. Important information about the microstructural characteristics of the material can be obtained from the comparison between neutron spectra before and after the interaction with the sample. In the NYR Laboratory, cylindrical samples of one inch of diameter have been traditionally studied. Nonetheless, there is a great motivation for doing systematic research on smaller and with different geometries samples; particularly sheets and samples for tensile tests. Hence, in the NYR Laboratory it has been considered the possibility of incorporating a neutron guide into the existent transmission line. According to all mentioned above, the main objective of this work consisted in the optimization of the flight transmission tube optics of neutrons. This optimization not only improved the existent line but also contributed to an election criterion for the neutron guide acquisition.

These low frequency resonance frequencies are very audible in the source room but also in neighbour rooms as a booming bass. CABS (Controlled Acoustic...... Bass System) is a time based room correction system for reproduced sound using loudspeakers. The system can remove room modes at low frequencies, by active cancelling the reflection from at the rear wall to a normal stereo setup. Measurements in a source room using CABS and in two neighbour rooms have...... shown a reduction in sound transmission of up to 10 dB at resonance frequencies and a reduction at broadband noise of 3 – 5 dB at frequencies up to 100 Hz. The ideas and understanding of the CABS system will also be given....

    Attention is an important, multifaceted cognitive domain that has been linked to three distinct, yet interacting, networks: alerting, orienting, and executive control. The measurement of attention and deficits of attention within these networks is critical to the assessment of many neurological and psychiatric conditions in both research and clinical settings. The Dalhousie Computerized Attention Battery (DalCAB) was created to assess attentional functions related to the three attention networks using a range of tasks including: simple reaction time, go/no-go, choice reaction time, dual task, flanker, item and location working memory, and visual search. The current study provides preliminary normative data, test-retest reliability (intraclass correlations) and practice effects in DalCAB performance 24-h after baseline for healthy young adults (n = 96, 18-31 years). Performance on the DalCAB tasks demonstrated Good to Very Good test-retest reliability for mean reaction time, while accuracy and difference measures (e.g., switch costs, interference effects, and working memory load effects) were most reliable for tasks that require more extensive cognitive processing (e.g., choice reaction time, flanker, dual task, and conjunction search). Practice effects were common and pronounced at the 24-h interval. In addition, performance related to specific within-task parameters of the DalCAB sub-tests provides preliminary support for future formal assessment of the convergent validity of our interpretation of the DalCAB as a potential clinical and research assessment tool for measuring aspects of attention related to the alerting, orienting, and executive control networks.

    High quality La2CaB10O19 single crystals doped with Pr3+ ions were grown by means of the top seeded solution growth method. The concentration of Pr3+ ions in the starting melt was equal to 4 at%, which, due to small distribution coefficient, in consequence gave single crystals containing 2.5 at% of Pr3+ions. The piezoelectric coefficients were measured for the pure and Pr+3 doped crystals. The principal changes under influence of the nanosecond pulsed 1064 nm Nd:YAG laser were observed for the LCBO nanocrystallites incorporated into the polymer matrices. The introduction of the Pr3+ ions favors enhanced piezoelectric constants. In turn the nanocrystallites with enhanced piezoelectricity lead to the enhanced laser threshold damage.

    CaWRKY40 is known to act as a positive regulator in the response of pepper (Capsicum annuum) to Ralstonia solanacearum inoculation (RSI) or high temperature-high humidity (HTHH), but the underlying mechanism remains elusive. Herein, we report that CabZIP63, a pepper bZIP family member, participates in this process by regulating the expression of CaWRKY40. CabZIP63 was found to localize in the nuclei, be up-regulated by RSI or HTHH, bind to promoters of both CabZIP63(pCabZIP63) and CaWRKY40(pCaWRKY40), and activate pCabZIP63- and pCaWRKY40-driven β-glucuronidase expression in a C- or G-box-dependent manner. Silencing of CabZIP63 by virus-induced gene silencing (VIGS) in pepper plants significantly attenuated their resistance to RSI and tolerance to HTHH, accompanied by down-regulation of immunity- or thermotolerance-associated CaPR1, CaNPR1, CaDEF1, and CaHSP24. Hypersensitive response-mediated cell death and expression of the tested immunity- and thermotolerance-associated marker genes were induced by transient overexpression (TOE) of CabZIP63, but decreased by that of CabZIP63-SRDX. Additionally, binding of CabZIP63 to pCaWRKY40 was up-regulated by RSI or HTHH, and the transcript level of CaWRKY40 and binding of CaWRKY40 to the promoters of CaPR1, CaNPR1, CaDEF1 and CaHSP24 were up-regulated by TOE of CabZIP63. On the other hand, CabZIP63 was also up-regulated transcriptionally by TOE of CaWRKY40. The data suggest collectively that CabZIP63 directly or indirectly regulates the expression of CaWRKY40 at both the transcriptional and post-transcriptional level, forming a positive feedback loop with CaWRKY40 during pepper's response to RSI or HTHH. Altogether, our data will help to elucidate the underlying mechanism of crosstalk between pepper's response to RSI and HTHH. PMID:26936828

    Graphical abstract: . Display Omitted Highlights: > Monolayer biofilm of Shewanella cells was prepared on an ITO electrode. > Extracellular electron transfer (EET) process was examined with series of mutants. > Direct ET was confirmed with outer-membrane-bound OmcA-MtrCAB complex. > The EET process was not prominently influenced by capsular polysaccharide. - Abstract: The direct electron-transfer (DET) property of Shewanella bacteria has not been resolved in detail due to the complexity of in vivo electrochemistry in whole-cell systems. Here, we report the in vivo assignment of the redox signal indicative of the DET property in biofilms of Shewanella oneidensis MR-1 by cyclic voltammetry (CV) with a series of mutants and a chemical marking technique. The CV measurements of monolayer biofilms formed by deletion mutants of c-type cytochromes ({Delta}mtrA, {Delta}mtrB, {Delta}mtrC/{Delta}omcA, and {Delta}cymA), and pilin ({Delta}pilD), capsular polysaccharide ({Delta}SO3177) and menaquinone ({Delta}menD) biosynthetic proteins demonstrated that the electrochemical redox signal with a midpoint potential at 50 mV (vs. SHE) was due to an outer-membrane-bound OmcA-MtrCAB protein complex of decaheme cytochromes, and did not involve either inner-membrane-bound CymA protein or secreted menaquinone. Using the specific binding affinity of nitric monoxide for the heme groups of c-type cytochromes, we further confirmed this conclusion. The heterogeneous standard rate constant for the DET process was estimated to be 300 {+-} 10 s{sup -1}, which was two orders of magnitude higher than that previously reported for the electron shuttling process via riboflavin. Experiments using a mutant unable to produce capsular polysaccharide ({Delta}SO3177) revealed that the DET property of the OmcA-MtrCAB complex was not influenced by insulating and hydrophilic extracellular polysaccharide. Accordingly, under physiological conditions, S. oneidensis MR-1 utilizes a high density of outer

    2011-01-01

    Sound reproduction is often taking place in small and medium sized rectangular rooms. As rectangular rooms have 3 pairs of parallel walls the reflections at especially low frequencies will cause up to 30 dB spatial variations of the sound pressure level in the room. This will take place not only at...... resonance frequencies, but more or less at all frequencies. A time based room correction system named CABS (Controlled Acoustic Bass System) has been developed and is able to create a homogeneous sound field in the whole room at low frequencies by proper placement of multiple loudspeakers. A normal setup...

  3. Optimizacion de una linea de espectrometria neutronica de transmision aplicada a ciencia de materiales para el acelerador lineal del CAB

    International Nuclear Information System (INIS)

    The Neutrons and Reactors Laboratory (NYR) of CAB (Centro Atomico Bariloche) is equipped with a linear electron accelerator (LINAC) Linear particle accelerator). This LINAC is used as a neutron source from which two beams are extracted to perform neutron transmission and dispersion experiments. Through these experiments, structural and dynamic properties of materials can be studied. The neutron transmission experiments consist in a collimated neutron beam which interacts with a sample and a detector behind the sample. Important information about the microstructural characteristics of the material can be obtained from the comparison between neutron spectra before and after the interaction with the sample. This experimental technique has been extensively used to determine cross sections, lattice parameters of a crystalline solid, vibration frequencies of atoms or the strain field of a material. In the NYR Laboratory, cylindrical samples of one inch of diameter have been traditionally studied. Nonetheless, there is a great motivation for doing systematic research on smaller and with different geometries samples; particularly sheets and samples for tensile tests. In such cases, a reduction of the spot size of the beam and an increase of its intensity would have a direct impact on minimizing measurement times. Hence, in the NYR Laboratory it has been considered the possibility of incorporating a neutron guide into the existent transmission line. According to all mentioned above, the main objective of this work consisted in the optimization of the flight transmission tube optics of neutrons. This optimization not only improved the existent line but also contributed to an election criterion for the neutron guide acquisition. The optimization was directed towards maximize the neutron flux on samples of mentioned geometries and to form the divergence of the incident beam upon them. It was then necessary to study the instrument neutron optics, i.e. the characteristics of the

    CIE (Commission Internationale de l'Eclairage) L(*)Cab(*)h(ab)° color coordinates for 305 samples of 17 unifloral honeys types (asphodel, buckwheat, black locust, sweet chestnut, citrus, eucalyptus, Garland thorn, honeydew, heather, lime, mint, rapeseed, sage, strawberry tree, sulla flower, savory and thistle) from different geographic locations in Europe were spectrophotometrically assessed and statistically evaluated. Preliminary separation of unifloral honeys was obtained by means of L(*)-C(ab)(*) color coordination correlation. Hierarchical Cluster Analysis (HCA) revealed an expected segregation of the honeys types according to their chromatic characteristics. Principal Component Analysis (PCA) allowed to obtain a more defined distinction of the 17 unifloral honey types, particularly when using 3D graphics. CIE L(*)C(ab)(*)hab(*) color coordinates were useful for the identification of several honey types. The proposed method represents a simple and efficient procedure that can be used as a basis for the authentication of unifloral honeys worldwide.

    Vascular plants contain abundant, light-harvesting complexes in the thylakoid membrane that are non-covalently associated with chlorophylls and carotenoids. These light-harvesting chlorophyll a/b binding (LHC) proteins are members of an extended CAB/ELIP/HLIP superfamily of distantly related polypeptides, which have between one and four transmembrane helices (TMH). This superfamily includes the single TMH, high-light-inducible proteins (Hlips), found in cyanobacteria that are induced by various stress conditions, including high light, and are considered ancestral to the LHC proteins. The roles of, and evolutionary relationships between, these superfamily members are of particular interest,since they function in both light harvesting and photoprotection and may have evolved through tandem gene duplication and fusion events. We have investigated the Hlips (hli gene family) in the thermophilic unicellular cyanobacterium Synechococcus OS-B'. The five hli genes present on the genome of Synechococcus OS-B' are relatively similar, but transcript analyses indicate that there are different patterns of transcript accumulation when the cells are exposed to various growth conditions, suggesting that different Hlips may have specific functions. Hlip5 has an additional TMH at the N-terminus as a result of a novel fusion event. This additional TMH is very similar to a conserved hypothetical, single membrane-spanning polypeptide present in most cyanobacteria. The evolutionary significance of these results is discussed.

    Excitation and emission spectra of new borate La2CaB10O19 doped Eu3+ in VUV-VIS range, high resolution emission spectra at room temperature and lifetime of Eu3+ were investigated. The emission line at about 616 nm attributed to the 5D0-7F2 transition of Eu3+ is the most intense emission of Eu3+. The broad band at about 244 nm is originated from charge transition band (CTB) of O2-→Eu3+. According to the numbers of spectral lines 5D0-7F0 and 5D0-7F1 in high-resolution spectrum, Eu3+ ions occupy two crystallographic sites. The lifetimes of 5D0-7F0 transition of Eu3+ of two kinds of lattice sites are individually 2.1 and 2.6 ms, and both are exponential decay. In the VUV excitation spectrum, complicated band between 130 and 170 nm consists of host absorption and f-d transition of Eu3+.

  16. The mechanism for the nonlinear optical properties in La9Na3B8O27, La2Na3B3O9 and La2CaB10O19: ab initio studies

    International Nuclear Information System (INIS)

    The nonlinear optical (NLO) properties in La9Na3B8O27, La2Na3B3O9 and La2CaB10O19 are investigated using a plane-wave pseudopotential method. Based on the first-principles electronic band structures, the birefringence and second harmonic generation (SHG) coefficients for the three crystals are determined. The calculated values match well with the experimental results. In order to elucidate the microscopic origins of the NLO performances in these crystals, a real-space atom-cutting method is adopted to calculate the contribution from the respective ions and groups. It is revealed that the La cations have covalent interactions with the neighbor O ions so as to form the La–O groups. The La–O bond covalency, combined with the distortion of La–O groups, makes the large contribution to the overall SHG coefficients in addition to the B–O groups, as also intuitively demonstrated by a SHG-density analysis.

    The objectives of this study were to test the effects of melatonin (N-acetyl-5-methoxytryptamine), a natural compound of edible plants on the rooting of certain commercial sweet cherry rootstocks. Shoot tip explants from previous in vitro cultures of the cherry rootstocks CAB-6P (Prunus cerasus L.), Gisela 6 (P. cerasus × P. canescens), and M × M 60 (P. avium × P. mahaleb) were included in the experiment. The effect of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) alone or in combination with melatonin was tested concerning their rooting potential. Seven concentrations of melatonin (0, 0.05, 0.1, 0.5, 1, 5, and 10 μM) alone or in combination with 5.71 μM of IAA or 4.92 μM of IBA were tested. For each rootstock, 21 treatments were included. The explants were grown in glass tubes containing 10 mL of substrate. The parameters measured include rooting percentage, number of roots per rooted explant, root length, and callus formation. The data presented in this study show that melatonin has a rooting promoting effect at a low concentration but a growth inhibitory effect at high concentrations. In the absence of auxin, 1 μM melatonin had auxinic response concerning the number and length of roots, but 10 μM melatonin was inhibitory to rooting in all the tested rootstocks. The final conclusion of this experiment is that exogenously applied melatonin acted as a rooting promoter and its action was similar to that of IAA. PMID:21749439

    Full Text Available A mecanização da colheita da cana-de-açúcar parece ser o caminho para solução dos problemas decorrentes dos impactos ambientais das queimadas e do trabalho extremamente fatigante na colheita manual. Por outro lado, a mecanização total da colheita levaria milhares de trabalhadores ao desemprego. Para minimizar os impactos ambientais e manter parte desses empregos, a Agricef e a Unicamp estão desenvolvendo o projeto da unidade mecânica de auxílio à colheita da cana-de-açúcar (UNIMAC CANA, baseado em um conceito alternativo representado pela mecanização parcial da colheita, que está em fase de prototipagem. Particularmente, esta pesquisa teve como objetivo o dimensionamento da cabine desse dispositivo e o posicionamento de seus comandos e painéis, com base nas características antropométricas do operador brasileiro. Utilizou-se a metodologia projetual orientada pela preocupação com aspectos ergonômicos. As alternativas de projeto geradas através de quadros morfológicos culminaram no dimensionamento da cabine da máquina com sua disposição de comandos, painel e assento, de modo a acomodar o operador de forma segura e confortável. Através de simulação do campo visual do operador, concluiu-se que a cabine, adotando posição móvel em relação à maquina, seria uma opção viável de projeto nos atributos conforto e dirigibilidade.Sugar cane harvesting mechanization seems to be the solution for the problems related to the environment impact of sugar cane burning and to facilitate manual harvesting, which also is a extremely hard task.

    The process of chloroplast differentiation, involves the coordinate regulation of many nuclear and chloroplast genes. The cues for the initiation of this developmental program are both extrinsic (e.g., light) and intrinsic (cell-type and plastid signals). During this project period, we utilized a molecular genetic approach to select for Arabidopsis mutants that did not respond properly to environmental light conditions, as well as mutants that were unable to perceive plastid damage. These latter mutants, called gun mutants, define two retrograde signaling pathways that regulate nuclear gene expression in response to chloroplasts. A major finding was to identify a signal from chloroplasts that regulates nuclear gene transcription. This signal is the build-up of Mg-Protoporphyrin IX, a key intermediate of the chlorophyll biosynthetic pathway. The signaling pathways downstream of this signal are currently being studied. Completion of this project has provided an increased understanding of the input signals and retrograde signaling pathways that control nuclear gene expression in response to the functional state of chloroplasts. These studies should ultimately influence our abilities to manipulate plant growth and development, and will aid in the understanding of the developmental control of photosynthesis.

    High-pressure phase transitions in CaRhO3 were examined using a multianvil apparatus up to 27 GPa and 1930 oC. CaRhO3 perovskite transforms to post-perovskite via a monoclinic intermediate phase with increasing pressure. Volume changes for the transitions of perovskite - intermediate phase and of intermediate phase - post-perovskite are -1.1 and -0.7 %, respectively. CaRhO3 post-perovskite is the fourth quenchable post-perovskite oxide found so far. By high-temperature calorimetric experiments, enthalpy of the perovskite - post-perovskite transition in CaRuO3 was measured as 15.2±3.3 kJ/mol. Combining the datum with those of CaIrO3, it is shown that CaIrO3 perovskite is energetically less stable than CaRuO3 perovskite. This is consistent with the fact that orthorhombic distortion of CaIrO3 perovskite is larger than CaRuO3, as indicated with the tilt-angle of octahedral framework of perovskite structure. The transition pressure from perovskite to post-perovskite in CaBO3 (B = Ru, Rh, Ir) increases almost linearly with decreasing the tilt-angle, suggesting that the perovskite - post-perovskite transition may result from instability of the perovskite structure with pressure.

  13. Design of a cold neutron source for 25MeV Linac of CAB (Centro Atomico Bariloche - Argentina)

    International Nuclear Information System (INIS)

    Cold neutrons are widely used in fields of research such as the dynamics of solids and liquids, the investigation of magnetic materials, material science, biology, and nuclear physics in general. Accelerator-based cold neutron sources have already proved to be well adapted to perform neutron scattering studies in all those fields.In this work we present the design of a cold neutron source in the electron Linac-based pulsed source at Centro Atomico Bariloche.The objective of this work is to develop an inexpensive yet efficient cold source with a simple moderator material.Although ideal materials for that purpose would be solid methane or liquid H2, due to economical and safety reasons light water ice, benzene or solid mesitylene were considered as cold moderators. In order to proceed with the design and optimization process of the neutron source, total cross sections for light water ice, benzene and mesitylene were measured at low temperature and thermal nuclear data libraries for such materials had to be developed.The purpose of these calculations was to optimize shape and size for the moderator at a working temperature.To calculations were performed using the MCNP-4C code and our libraries, together with files for (free-atom) carbon, hydrogen and oxygen at that temperature.The geometry studied consisted of a neutron source and different moderator (slab, cylindrical slab, grids, and sets premoderator - moderator with and without coupled).To simplify the system cooler, the slab geometry was changed to a coin shaped moderator using liquid nitrogen as cooler.From the variety of simulations performed, it was clear that a premoderator was necessary to obtain higher intensities.Furthermore, with a premoderator the thickness of the moderator was reduced, simplifying the cooling system.Finally, we adopted for our cold neutron source, a slab premoderator of PLE at room temperature, and a cylindrical moderator of mesitylene at 89K with a cooler system of stainless steel with windows of Zircaloy-4

Como filho do penúltimo amusnaw (sábio; bardo de sua tribo, Mammeri estava posicionado de maneira única para situar esse mestre das palavras que atuou na função tradicional de mediador e transportador do conhecimento e manteve-se como a encarnação viva da tamusni (a filosofia prática da excelência berbere, em relação com o marabuto (depositário das sagradas escrituras do Corão e com os camponeses (que compõem seu público principal. Torná-se amusnaw graças a uma eleição e isso requer um duplo aprendizado: primeiro, por osmose em um meio saturado de comércio e disputas verbais (no treinamento de guerra, na assembléia da vila, nos mercados e nas peregrinações e, depois, por meio de um treinamento explícito com um poeta-mestre que orienta uma série de exercícios e provas. Esse processo requer não apenas o domínio de uma variedade de técnicas verbais e de um cânone oratório, mas também implica absorver e encarnar a sabedoria. Jogando com a multidimensionalidade da linguagem, adaptando-a com flexibilidade diante das especificidades de cada situação e público, o bardo cabila era continuamente testado e suas habilidades culturais infinitamente refinadas, até o ponto em que ele não apenas dominasse as regras do ofício, mas também jogasse com elas, trangredindo-as no espírito da tradição a fim de inventar novas figuras retóricas e extrair o máximo de "rendimento" da linguagem. A tamusni emerge assim não apenas como um corpo de conhecimento inerte, desligado da vida e transmitido por si mesmo, mas como uma "ciência prática", constantemente revivida pela e para a prática. O poeta é o porta-voz do grupo que, por meio de seu discernimento cultural e uso técnico da linguagem, aperfeiçoa os valores específicos do grupo, separa coisas que são confusas e, ao iluminar o que é obscuro, mobiliza seu povo.

    At present, rational planning and development technologies are just as much in demand as rational production processes. In the continuous search for efficient development methods, ergonomy must also be taken into account. However, the extent to which ergonomic principles are applied depends to a high degree on persons who are called upon to contribute their expertise in this field creatively in product development in addition to their normal jobs. If the constructors and designers succeed in using tools with which ergonomic design principles can be implemented more quickly and reliably as the basis of their design process, this is then an important contribution to minimising development times and costs. After extensive research, the designer team decided to test the efficiency of an ergonomy tool in routine use on a project with limited time for which values for comparison are available from previous tests. A specific urgent task was a welcome opportunity for MAN AG to test a certain combined computer-aided ergonomy method in order to determine from the experience gained with it whether and how it may be applied in future and what the output of the application actually has to offer to the developers and the product. (orig.) [Deutsch] Rationelle Planungs- und Entwicklungstechnologien - die Ergonomie eingeschlossen - sind heute genauso gefragt wie rationelle Produktionsverfahren. Wenn es den Konstrukteuren und Designern gelingt, Werkzeuge einzusetzen, mit denen ergonomische Gestaltungsprinzpien als Grundlage ihres Entwurfsprozesses schneller und sicherer erarbeitet werden koennen, dann ist auch dies ein wichtiger Beitrag zur Minimierung der Entwicklungszeiten und -kosten. Deshalb entschied sich das Designerteam, die Effizienz eines Ergonomiewerkzeuges im Betriebsalltag an einem zeitlich begrenzten Projekt, fuer das Vergleichswerte aus zurueckliegenden Pruefungen mit anderen Methoden vorliegen, zu testen. Dabei sollte festgestellt werden, ob und wie es vielleicht zukuenftig eingesetzt werden kann und welchen Wert das Anwendungsergebnis ingesamt fuer die Entwickler und fuer das Produkt darstellt.

    Full Text Available To better understand the molecular mechanisms of Ethambutol (EMB resistance, the mutant hot spot region of five genes (embB, embA, embC, embR, and ubiA was amplified and sequenced in 109 EMB-resistant and 153 EMB-susceptible clinical isolates from China. Twenty-seven EMB-susceptible isolates were found to have nonsynonym mutations, 23 of which were in embB. The mutations occurred most frequently in embB (85.3%, 93 and were seldom in embC (2.8%, 3, embA (3.7%, 4, embR (3.7%, 4, and ubiA (8.3%, 9 in EMB-resistant isolates. For the embB gene, 63 isolates showed mutations at embB306, 20 at embB406, nine at embB497, and five at embB354 in EMB-resistant isolates. In addition, the particular mutants at embB406 and embB497 indicated both high levels of EMB resistance (MICs>5 μg/mL and broad anti-TB drug resistance spectrums. Our data supported the facts that embB306 could be used as a marker for EMB resistance with a sensitivity of 57.8% and a specificity of 78.8%.

  3. Luminescence of Bi3+ in the orthorhombic perovskites CaB4+O3 (B4+=Zr, sn): Crossover from localized to D-state emission

    Science.gov (United States)

    Srivastava, Alok M.

    2016-08-01

    The optical properties of Bi3+ in the orthorhombic perovskites CaZrO3 and CaSnO3 are investigated. The Stokes shift of Bi3+ emission in CaZrO3 is small (∼0.80 eV) with the peak wavelength of the emission band occurring in the ultraviolet. This emission is attributed to the localized 3P0,1 → 1S0 optical transition. In contrast, the Stokes shift of the Bi3+ emission in CaSnO3 is large (>1 eV) with the emission band peaking in the visible. The emission band is also considerably broadened in CaSnO3. It is claimed that Bi3+ luminescence in CaSnO3 corresponds with the Bi3+ (6s2) -Sn4+ (5s°) charge transfer emission (D-state emission). The energy of the 1S0→3P1 (A-band) excitation band in both perovskites are very nearly the same. Physical reasoning is advanced for the occurrence and lack thereof of the D-state emission in these perovskites.

    Trees, C.C.

    1994-04-22

    This study started on 1 June 1989 and ended 14 November 1991. Two moored in situ natural fluorometers were deployed in January 1990 to collect bio-optical data for one year, making ground truth measurements around the mooring during 4 cruises. This one-year time series would investigate how the short-term physical forcing aliases the long-term primary production record such that the apparent, larger interannual variability in the record is in reality ``noise`` due to short-term fluctuations in the rate of nutrient input to the euphotic zone. These continuous measurements from moored bio-optical instruments would also allow better estimates of the mean and variance in primary production in these waters than has previously been available from shipboard measurements, as well as, phytoplankton response to short-term physical events. Ancillary measurements that were made were: (1) characterization of the apparent and inherent optical properties, (2) photosynthetic pigment distributions using both HPLC and standard fluorometric methods, (3) carbon, hydrogen and nitrogen content of suspended particulate matter, (4) primary production using conventional {sup 14}C methods from simulated in situ experiments.

  20. Profiling antibody responses to infections by Chlamydia abortus enables identification of potential virulence factors and candidates for serodiagnosis.

    Directory of Open Access Journals (Sweden)

    Vera Forsbach-Birk

    Full Text Available Enzootic abortion of ewes (EAE due to infection with the obligate intracellular pathogen Chlamydia (C. abortus is an important zoonosis leading to considerable economic loss to agriculture worldwide. The pathogen can be transmitted to humans and may lead to serious infection in pregnant women. Knowledge about epidemiology, clinical course and transmission to humans is hampered by the lack of reliable diagnostic tools. Immunoreactive proteins, which are expressed in infected animals and humans, may serve as novel candidates for diagnostic marker proteins and represent putative virulence factors. In order to broaden the spectrum of immunogenic C. abortus proteins we applied 2D immunoblot analysis and screening of an expression library using human and animal sera. We have identified 48 immunoreactive proteins representing potential diagnostic markers and also putative virulence factors, such as CAB080 (homologue of the "macrophage infectivity potentiator", MIP, CAB167 (homologue of the "translocated actin recruitment protein", TARP, CAB712 (homologue of the "chlamydial protease-like activity factor", CPAF, CAB776 (homologue of the "Polymorphic membrane protein D", PmpD, and the "hypothetical proteins" CAB063, CAB408 and CAB821, which are predicted to be type III secreted. We selected two putative virulence factors for further characterization, i.e. CAB080 (cMIP and CAB063, and studied their expression profiles at transcript and protein levels. Analysis of the subcellular localization of both proteins throughout the developmental cycle revealed CAB063 being the first C. abortus protein shown to be translocated to the host cell nucleus.

    Cabergoline (CAB), the first-line drug for treatment of prolactinomas, is effective in suppressing prolactin hypersecretion, reducing tumor size, and restoring gonadal function. However, mechanisms for CAB-mediated tumor shrinkage are largely unknown. Here we report a novel cytotoxic mechanism for CAB. CAB induced formation of autophagosome in rat pituitary tumor MMQ and GH3 cells at the early stage through inhibiting mTOR pathway, resulting in higher conversion rates of LC3-I to LC3-II, GFP-LC3 aggregation, and increased autophagosome formation. Interestingly, CAB treatment augmented lysosome acidification and resulted in impaired proteolytic degradation within autolysosomes. This blocked the autophagic flux, leading to the accumulation of p62 aggregation and undigested autolysosomes. Knockdown of ATG7, ATG5, or Becn1, could significantly rescue the CAB-mediated cell death of MMQ cells (p < 0.05). CAB-induced autophagy and blockade of autophagy flux participated in antitumoral action in vivo. In conclusion, our study provides evidence that CAB concomitantly induces autophagy and inhibits the autophagic flux, leading to autophagy-dependent cell death. These findings elucidate novel mechanisms for CAB action. PMID:26513171

    Full Text Available The current study deals with the evaluation of two coral-associated bacterial (CAB extracts to inhibit the biofilm synthesis in vitro as well as the virulence production like hemolysin and exopolysaccharide (EPS, and also to assess their ability to modify the adhesion properties, that is cell surface hydrophobicity (CSH of methicillin-resistant (MRSA and -susceptible Staphylococcus aureus (MSSA. Out of nine CAB screened, the ethyl acetate extract of CAB-E2 (Bacillus firmus and CAB-E4 (Vibrio parahemolyticus have shown excellent antibiofilm activity against S. aureus. CAB-E2 reduced the production of EPS (57–79% and hemolysin (43–70%, which ultimately resulted in the significant inhibition of biofilms (80–87% formed by both MRSA and MSSA. Similarly, CAB-E4 was also found to decrease the production of EPS (43–57%, hemolysin (43–57% and biofilms (80–85% of test pathogens. CLSM analysis also proved the antibiofilm efficacy of CAB extracts. Furthermore, the CAB extracts strongly decreased the CSH of S. aureus. Additionally, FT-IR analysis of S. aureus treated with CAB extracts evidenced the reduction in cellular components compared to their respective controls. Thus, the present study reports for the first time, B. firmus—a coral-associated bacterium, as a promising source of antibiofilm agent against the recalcitrant biofilms formed by multidrug resistant S. aureus.

    1. Cabotegravir (CAB; GSK1265744) is a potent HIV integrase inhibitor in clinical development as an oral lead-in tablet and long-acting injectable for the treatment and prevention of HIV infection. 2. This work investigated if CAB was a substrate for efflux transporters, the potential for CAB to interact with drug-metabolizing enzymes and transporters to cause clinical drug interactions, and the effect of CAB on the pharmacokinetics of midazolam, a CYP3A4 probe substrate, in humans. 3. CAB is a substrate for Pgp and BCRP; however, its high intrinsic membrane permeability limits the impact of these transporters on its intestinal absorption. 4. At clinically relevant concentrations, CAB did not inhibit or induce any of the CYP or UGT enzymes evaluated in vitro and had no effect on the clinical pharmacokinetics of midazolam. 5. CAB is an inhibitor of OAT1 (IC50 0.81 µM) and OAT3 (IC50 0.41 µM) but did not or only weakly inhibited Pgp, BCRP, MRP2, MRP4, MATE1, MATE2-K, OATP1B1, OATP1B3, OCT1, OCT2 or BSEP. 6. Based on regulatory guidelines and quantitative extrapolations, CAB has a low propensity to cause clinically significant drug interactions, except for coadministration with OAT1 or OAT3 substrates.

    Country Analysis Briefs: 1994 is a compilation of country profiles prepared by the Energy Markets and Contingency Information Division (EMCID) of the Office of Energy Markets and End Use. EMCID maintains Country Analysis Briefs (CABs) for specific countries or geographical areas that are important to world energy markets. As a general rule, CABs are prepared for all members of the Organization of Petroleum Exporting Countries (OPEC), major non-OPEC oil producers (i.e., the North Sea, Russia), major energy transit areas (i.e., Ukraine), and other areas of current interest to energy analysts and policy makers. As of January 1995, EMCID maintained over 40 CABs, updated on an annual schedule and subject to revision as events warrant. This report includes 25 CABs updated during 1994. All CABs contain a profile section, a map showing the country`s location, and a narrative section. The profile section includes outlines of the country`s economy, energy sector, and environment. The narrative provides further information and discussion of these topics. Some CABs also include a detailed map displaying locations of major oil and gas fields, pipelines, ports, etc. These maps were created as a result of special individual requests and so are not typically a standard feature of the CABs. They are presented here wherever available as a supplement to the information contained in the CABs.

  1. ALP conversion and the soft X-ray excess in the outskirts of the Coma cluster

    International Nuclear Information System (INIS)

    It was recently found that the soft X-ray excess in the center of the Coma cluster can be fitted by conversion of axion-like-particles (ALPs) of a cosmic axion background (CAB) to photons. We extend this analysis to the outskirts of Coma, including regions up to 5 Mpc from the center of the cluster. We extract the excess soft X-ray flux from ROSAT All-Sky Survey data and compare it to the expected flux from ALP to photon conversion of a CAB. The soft X-ray excess both in the center and the outskirts of Coma can be simultaneously fitted by ALP to photon conversion of a CAB. Given the uncertainties of the cluster magnetic field in the outskirts we constrain the parameter space of the CAB. In particular, an upper limit on the CAB mean energy and a range of allowed ALP-photon couplings are derived

The same growth period under different processing, Fv/Fm, Fv/F0, Yield, ETR, qP were increasing as fertilizer rate increasing, NPQ increases during rosette period, and became lower during knot bal period. Different growth period and fertilizer's interaction on Fm, Fv/Fm, Fv/F0, NPQ were very significant (P结球期;表观光合电子传递速率(ETR)、光化学淬灭系数(qP)、相对叶绿素含量(SPAD)为结球期>莲座期。同一生长期不同处理下,Fv/Fm、Fv/F0、Yield、ETR、qP均是随着施肥量增加而增加,NPQ则为莲座期增加,结球期又降低。不同生长期不同施肥量交互作用对Fm、Fv/Fm、Fv/F0、NPQ影响极显著(P<0.01),对qP影响显著(P<0.05)。这说明增施竹炭有机肥对有机卷心菜叶绿素荧光指标和相对叶绿素含量有显著影响,且BC60处理下更有助于其光合固碳,增加产量,符合低碳有机农业宗旨。

    Objective To investigate the aciduricity and genetic diversity of ATP synthase subunit gene uncEBF derived from Uyghur children Streptococcus mutans (Sm) clinical isolates and the relationship between the genetic diversity of ATP synthase and Sm aciduric ability and cavies susceptibility.Methods Forty-one Sm strains derived from 24 caries-active individuals and 17 caries-free individuals,including 16 strains displaying high acid tolerance and 17 strains displaying low acid tolerance.Solutions of all isolated Sm with same density were made and cultured at pH 4.0 to 7.0 brain heart infusion(BHI) liquid.Terminal growth situation was compared.Gene uncEBF of these isolates were amplified with specific primers from Sm genomic DNA,and the polymerase chain reaction(PCR) products were analyzed by PCR-restriction fragment length polymorphism (RFLP) and sequenced. Results Aciduric ability of Sm isolated from the high caries-susceptible children were higher than that isolated from caries-free group(P =0.023).Alu Ⅰ digested fragments of uncEBF displayed two different patterns A and B.The distributions of A and B genotype strains with different acidurance were different ( P =0.039 ). A genotype included 7 strains displaying high acid tolerance and 2 strains displaying low acid tolerance; B genotype included 9 strains displaying highacid tolerance and 15 strains displaying low acid tolerance.The distributions of A and B genotype strains in different caries-sensitivity groups were different( P =0.009 ).A genotype included 7 high caries-susceptible strains and 12 caries-free strains;B genotype included 17 high caries-susceptible strains and 5 caries-free strain.Some of these amplified uncEBF genes from different genotype were sequenced and testified that there existed variation of Alu Ⅰ recognized sites.Conclusions The high cariogenecity of Sm strains isolated from caries-active children shows a close relationship with the high aciduric ability of the isolated Sm strains.uncEBF gene of Sm F-ATPase obviously exhibits genetic diversity.%目的 探讨新疆维吾尔族不同龋敏感儿童变形链球菌临床分离株耐酸性及耐酸因子质子转运ATP合酶亚基cab基因多态性与耐酸力和龋敏感性的相关性,以期为新疆维吾尔族儿童龋病防治提供依据.方法 选取新疆维吾尔族自治区乌鲁木齐市3~5岁维吾尔族高龋(龋失补牙数≥5)和无龋(龋失补牙数=0)儿童口腔中分离的变形链球菌24和17株,采用紫外分光光度计测定540 nm处吸光度值,比较不同pH条件下细菌的生长情况并筛选出16株高耐酸、17株低耐酸菌株,以特异引物从细菌组DNA扩增uncEBF,采用聚合酶链反应-限制性片段长度多态性分析技术对酶切图谱行基因分型,结合核酸测序技术比较导致基因型突变的位点.结果 pH值为5.0时,高龋者变形链球菌生长能力[A值为(0.702 ±0.157)]较无龋者[A值为(0.372±0.123)]强,差异有统计学意义(P =0.023);不同限制性片段长度多态性分析产生不同的基因型,测序结果证实了导致多态性出现的基因变异位点;其中内切酶Alu Ⅰ产生的A基因型在高、低耐酸力菌株中的分布分别为7和2株,B基因型在高、低耐酸力菌株中的分布分别为9和15株,基因型分布在不同耐酸力菌株中差异有统计学意义(P=0.039);A基因型在无龋、高龋儿童菌株中的分布分别为12和7株,B基因型在无龋、高龋儿童菌株中的分布分别为5和17株,基因型分布在不同龋敏感菌株中差异有统计学意义(P=0.009).结论 维吾尔族高龋儿童口腔中变形链球菌临床分离株具有高致龋性,且耐酸因子质子转运ATP合酶亚基联合基因uncEBF具有明显的基因多态性,不同基因型uncEBF分布与耐酸力及龋敏感性具有相关性.

    Full Text Available Successful discontinuation of cabergoline (CAB treatment has been reported in 31 to 74% of prolactinomas patients treated for at least two years. In contrast, it is not well established whether CAB therapy can be successfully withdrawn after a failed first attempt. This prospective open trial was designed to address this topic and to try to identify possible predictor factors.Among 180 patients with prolactinomas on CAB therapy, the authors selected those who fulfilled very strict criteria, particularly additional CAB therapy for at least 2 years, normalization of serum prolactin (PRL levels following CAB restart, no tumor remnant > 10 mm, no previous pituitary radiotherapy or surgery; and current CAB dose ≤1.0 mg/week. Recurrence was defined as an increase of PRL levels above the upper limit of normal.A total of 34 patients (70.6% female treated with CAB for 24-30 months were recruited. Ten patients (29.4 % remained without evidence of recurrence after 24–26 months of follow-up. Twenty-four patients (70.6% recurred within 15 months (75% within 12 months after drug withdrawal and ~80% were restarted CAB. Median time to recurrence was 10.5 months (range, 3–15. Despite overlapping values, non-recurring patients had significantly lower mean PRL levels before withdrawal. Moreover, the recurrence rate was lower in subjects without visible tumor on pituitary MRI than in those with small remnant tumor (60 vs. 79%, though the difference was not statistically significant (P= 0.20. No other characteristic could be identified as a predictor of successful CAB discontinuation.In conclusion, a second attempt of CAB withdrawal after 2 additional years of therapy may be successful, particularly in patients with lower PRL levels and no visible tumor on pituitary MRI. Close monitoring of PRL level is mandatory, especially within the first year after withdrawal, where most recurrences are detected.

    Problematic alcohol use among college students continues to be a prominent concern in the United States, including the growing trend of consuming caffeinated alcoholic beverages (CABs). Epidemiologically, CAB use is associated with incremental risks from drinking, although these relationships could be due to common predisposing factors rather than specifically due to CABs. This study investigated the relationship between CAB use, alcohol misuse, and person-level characteristics, including impulsive personality traits, delayed reward discounting, and behavioral economic demand for alcohol use. Participants were 273 regularly drinking undergraduate students. Frequency of CAB use was assessed over the past month. A multidimensional assessment of impulsivity included the UPPS-P questionnaire, which measures positive and negative urgency, premeditation (lack thereof), perseverance (lack thereof), and sensation seeking (Lynam, Smith, Whiteside, & Cyders, 2007), and a validated questionnaire-based measure of delayed reward discounting. Demand was assessed via a hypothetical alcohol purchase task. Frequency of CAB consumption was significantly higher in men than in women and was also associated with higher impulsivity on the majority of the UPPS-P subscales, steeper delayed reward discounting, and greater demand for alcohol. Significant correlations between CAB use and both alcohol demand and lack of premeditation remained present after including level of alcohol misuse in partial correlations. In a hierarchical linear regression incorporating demographic, demand, and impulsivity variables, CAB frequency continued to be a significant predictor of hazardous alcohol use. These results suggest that although there are significant associations between CAB consumption and gender, impulsivity, and alcohol demand, CAB use continues to be associated with alcohol misuse after controlling for these variables.

  8. Protonated form: the potent form of potassium-competitive acid blockers.

    Directory of Open Access Journals (Sweden)

    Full Text Available Potassium-competitive acid blockers (P-CABs are highly safe and active drugs targeting H+,K+-ATPase to cure acid-related gastric diseases. In this study, we for the first time investigate the interaction mechanism between the protonated form of P-CABs and human H+,K+-ATPase using homology modeling, molecular docking, molecular dynamics and binding free energy calculation methods. The results explain why P-CABs have higher activities with higher pKa values or at lower pH. With positive charge, the protonated forms of P-CABs have more competitive advantage to block potassium ion into luminal channel and to bind with H+,K+-ATPase via electrostatic interactions. The binding affinity of the protonated form is more favorable than that of the neutral P-CABs. In particular, Asp139 should be a very important binding site for the protonated form of P-CABs through hydrogen bonds and electrostatic interactions. These findings could promote the rational design of novel P-CABs.

    Many bacteria form Gln-tRNAGln and Asn-tRNAAsn by conversion of the misacylated Glu-tRNAGln and Asp-tRNAAsn species catalyzed by the GatCAB amidotransferase in the presence of ATP and an amide donor (glutamine or asparagine). Here we report the crystal structures of GatCAB from the hyperthermophilic bacterium Aquifex aeolicus complexed with glutamine, asparagine, aspartate, ADP, or ATP. In contrast to the Staphylococcus aureus GatCAB, the A. aeolicus enzyme formed acyl-enzyme intermediates wi...

    This study presents a combined analytical and experimental effort to characterize and improve the ride quality of the Department of Energy tractor/trailer combination. The focus is to augment the experimental test results with the use of a high quality computer model. The discussion includes an overview of the finite element model of the vehicle and experimental modal test results. System identification techniques are employed to update the mathematical model. The validated model is then used to illustrate the benefits of incorporating two major design changes, namely the switch from a separate cab/sleeper configuration to an integrated cab, and the use of a cab suspension system.

  1. Children in pickup trucks. American Academy of Pediatrics. Committee on Injury and Poison Prevention.

    Science.gov (United States)

    2000-10-01

    Pickup trucks have become increasingly popular in the United States. A recent study found that in crashes involving fatalities, cargo area passengers were 3 times more likely to die than were occupants in the cab. Compared with restrained cab occupants, the risk of death for those in the cargo area was 8 times higher. Furthermore, the increased use of extended-cab pickup trucks and air bag-equipped front passenger compartments creates concerns about the safe transport of children. The most effective preventive strategies are the legislative prohibition of travel in the cargo area and requirements for age-appropriate restraint use and seat selection in the cab. Parents should select vehicles that are appropriate for the safe transportation needs of the family. Physicians have an important role in counseling families and advocating public policy measures to reduce the number of deaths and injuries to occupants of pickup trucks. PMID:11015537

    The recent definitions on intra-abdominal pressure (IAP), intra-abdominal volume (IAV) and abdominal compliance (Cab) are a step forward in understanding these important concepts. They help our understanding of the pathophysiology, aetiology, prognosis, and treatment of patients with low Cab. However, there is still a relatively poor understanding of the different methods used to measure IAP, IAV and Cab and how certain conditions may affect the results. This review will give a concise overview of the different methods to assess and estimate Cab; it will list important conditions that may affect baseline values and suggest some therapeutic options. Abdominal compliance (Cab), defined as a measure of the ease of abdominal expansion, is measured differently than IAP. The compliance of the abdominal wall is only a part of the total abdominal pressure-volume (PV) relationship. Measurement or estimation of Cab is difficult at the bedside and can only be done in a case of change (removal or addition) in IAV. The different measurement techniques will be discussed in relation to decreases (ascites drainage, haematoma evacuation, gastric suctioning) or increases in IAV (gastric insufflation, laparoscopy with CO₂ pneumoperitoneum, peritoneal dialysis). More specific techniques using the interactions between the thoracic and abdominal compartment during positive pressure ventilation will also be discussed (low flow PV loop, respiratory IAP variations, respiratory abdominal variation test, mean IAP and abdominal pressure variation), together with the concept of the polycompartment model. The relation between IAV and IAP is linear at low IAV and becomes curvilinear and exponential at higher volumes. Specific conditions in relation to increased (previous pregnancy or laparoscopy, gynoid fat distribution, ellipse-shaped internal abdominal perimeter) or decreased Cab (obesity, fluid overload, android fat distribution, sphere-shaped internal abdominal perimeter) will be discussed

  7. Epidemiology, microbiology and mortality associated with community-acquired bacteremia in northeast Thailand: a multicenter surveillance study.

    Directory of Open Access Journals (Sweden)

    Manas Kanoksil

    Full Text Available BACKGROUND: National statistics in developing countries are likely to underestimate deaths due to bacterial infections. Here, we calculated mortality associated with community-acquired bacteremia (CAB in a developing country using routinely available databases. METHODS/PRINCIPAL FINDINGS: Information was obtained from the microbiology and hospital database of 10 provincial hospitals in northeast Thailand, and compared with the national death registry from the Ministry of Interior, Thailand for the period between 2004 and 2010. CAB was defined in patients who had pathogenic organisms isolated from blood taken within 2 days of hospital admission without a prior inpatient episode in the preceding 30 days. A total of 15,251 CAB patients identified, of which 5,722 (37.5% died within 30 days of admission. The incidence rate of CAB between 2004 and 2010 increased from 16.7 to 38.1 per 100,000 people per year, and the mortality rate associated with CAB increased from 6.9 to 13.7 per 100,000 people per year. In 2010, the mortality rate associated with CAB was lower than that from respiratory tract infection, but higher than HIV disease or tuberculosis. The most common causes of CAB were Escherichia coli (23.1%, Burkholderia pseudomallei (19.3%, and Staphylococcus aureus (8.2%. There was an increase in the proportion of Extended-Spectrum Beta-Lactamases (ESBL producing E. coli and Klebsiella pneumoniae over time. CONCLUSIONS: This study has demonstrated that national statistics on causes of death in developing countries could be improved by integrating information from readily available databases. CAB is neglected as an important cause of death, and specific prevention and intervention is urgently required to reduce its incidence and mortality.

  11. Controlled and high throughput fabrication of poly(trimethylene terephthalate) nanofibers via melt extrusion of immiscible blends

    International Nuclear Information System (INIS)

    Immiscible blends of cellulose acetate butyrate (CAB) and poly(trimethylene terephthalate) (PTT) were melt extruded through a two strand rod die. The extrudates were hot-drawn at the die exit at different draw ratios. PTT fibers were obtained by removal of the CAB matrix from the drawn extrudates, and the morphology evolution of the formed fibers was investigated by scanning electron microscopy. PTT nanofibers with an average diameter of 55 nm were produced by controlling the drawing ratio.

  12. The circulating air barrier: Effective prevention of liquid contaminant movement through soil

    International Nuclear Information System (INIS)

    Objectives of this task included design, modeling, selection of drilling and surface processing equipment, and development of test procedures and cost estimates for conducting a cold test demonstration of the Circulating Air Barrier (CAB) process. The demonstration configuration is scaled to a prototype CAB system designed specifically for the C Tank Farm at the Hanford Site. The CAB system is designed to function as a containment barrier to prevent contamination of the water table located approximately 200 feet below the base of the C-Tank-Farm underground storage tanks. The CAB system is a desiccant-type barrier designed to prevent the migration of liquid contaminants toward the ground water by using an air circulation and processing system to lower the saturation in a targeted subsurface zone below the saturation level required for liquid flow through that zone. The CAB system offers several important advantages, including the fact that it is a non-physical confinement technology, it has an active monitoring and leak detection capability, it is based on proven, commercially available equipment and oil and gas technologies; it has excellent potential for emergency response and rapid deployment; and offers high potential for integration with other remediation technologies. Demonstration- and full-scale CAB systems have been designed for the Hanford Site as part of this task

    During the last ten years there has been an interest for determining the prevalence and incidence of dementia among older adults and for cognitive tests that do to discriminate by level of education. This article revolves around the validation of a minimental exam, the Cabán minimental, to measure the cognitive capacity of Spanish-speaking adults 60 years of age and older; a test that is not affected by level of education. The factors measured in the Cabán minimental are: orientation, visual and motor coordination, learning, recent memory and abstraction. The validation process underwent two phases. During the first one, the Cabán test was subjected to construct validation and internal and predictive consistency tests. The second stage comprised a comparison between the Cabán and Folstein minimentals. The Cabán showed a statistically significant difference to discriminate for subjects with dementia. Results also suggest that the Cabán is not as much affected as the Folstein by differences in education. PMID:14768504

Physicians still may choose to administer CAB to such patients. We described the use of CAB and LF-AMB in this population and quantified differences in post-amphotericin B length of stay (LOS among survivors and hospital mortality in matched patients. Methods: Data were extracted from Health Facts (Cerner Corporation, Kansas City, MO, USA for a retrospective cohort analysis. Inpatients aged ≥18 years with evidence of fungal infection and with orders for LF-AMB or CAB on  ≥2 days from January 2001 to June 2010 were identified. Patients were required to have renal insufficiency or other relative contraindications to use of CAB, exposure to nephrotoxic agents, or evidence of a CAB-refractory infection. Multilevel (hierarchical mixed-effects logistic regression was used to determine factors associated with initial exposure to LF-AMB versus CAB. Multivariate adjustment of outcomes was done using propensity score matching. Results: 655 patients were identified: 322 patients initiated therapy with CAB and 333 initiated treatment with LF-AMB. Compared to those initiating CAB, patients initiating LF-AMB had greater acuity and underlying disease severity. In unadjusted analyses, hospital mortality was significantly higher in the LF-AMB group (32.2% versus 23.7%; P = 0.02. After propensity score matching and covariate adjustment, mortality equalized and observed differences in LOS after amphotericin B initiation decreased. Conclusion

    Research shows that heavier alcohol use is associated with physical aggression. Scant research has examined the way in which alcohol relates to other forms of aggression, such as indirect aggression (e.g., malicious humor, social exclusion). Given the possible negative consequences of indirect aggression and the limited evidence suggesting alcohol use can elicit indirectly aggressive responses, research is needed to further investigate the association between drinking behavior and indirect aggression. Additionally, specific alcoholic beverages, such as caffeinated alcoholic beverages (CABs; e.g., Red Bull and vodka), may potentiate aggression above the influence of typical use, and thus warrant examination with regard to indirect aggression. One factor that may impact the strength of the alcohol-indirect aggression and CAB-indirect aggression relationships is one's level of self-regulation. Consequently, our study examined the relationships between (1) alcohol use and indirect aggression, (2) CAB use and indirect aggression, and (3) self-regulation as a moderator. Participants were 733 (67.6% female) undergraduate students who reported their CAB and alcohol use, self-regulation, and aggressive behaviors. Results revealed that heavier alcohol use was associated with more frequent indirect aggression after controlling for dispositional aggression. Heavier CAB use was related to more frequent indirect aggression after accounting for typical use and dispositional aggression. Self-regulation moderated these associations such that for those with lower self-regulation, greater alcohol and CAB consumption was associated with greater indirect aggression. Our findings suggest that heavier alcohol and CAB consumption may be risk factors for engaging in indirect aggression and this risk is impacted by one's regulatory control. PMID:26905765

  16. Citizen advisory boards: An empirical model for choosing goals and methods

    International Nuclear Information System (INIS)

    This is a study of Citizen Advisory Boards (CABS) undertaken for the Department of Energy (DOE) to draw practical insights from the accumulated experience of CAB members and agency officials who have worked with these boards over many years. Hence the main research tool is in-depth interviews of these individuals. In addition, the study relies on field observations of CABs at work, historical documentation of individual boards, and a large body of academic, professional, and government literature. The DOE is in the process of establishing Site Specific Advisory Boards (SSABs) at most of its major facilities in order to provide for community involvement in the DOE environmental restoration and environmental management programs, but these boards initiated by DOE do not yet have enough of a track-record for a study of this type. Consequently, the study focused on CABs at six other federal agencies which have had substantial experience with boards that are similar in composition and purpose to the SSABs. The study examined common problem that confront virtually every CAB in its organization and its decision-making process. For example, each board faces difficult issues in defining its goals and representational responsibilities, selection of members, selection of issues, reaching agreement on recommendations to the parent agency, getting responsive action from the parent agency, and evaluating the board's success over time. An effort was made to identify solutions or best approaches to these fundamental problems such that the recommended approach has broad application to citizen advisory boards concerned with environmental issues. The conclusions of the study are summarized in a model which incorporates the optimal approaches discovered with respect to each of the critical issues. While acknowledging that the particular circumstances of a CAB may call for individual variations, the model provides a fairly comprehensive description of recommended features of a CAB

All indexes of infarct size were lower in the postbypass group. There was more ventricular fibrillation in the postbypass group. In-hospital mortality was similar (p = 0.3675. In the follow-up period, postbypass patients had more heart failure, recurrent CABS, reinfarction, and unstable angina than did control patients. Cumulative survival was better in the control group than in the postbypass group (p = 0.0403. Multiple logistic regression model showed that previous angina (p = 0.0005, diabetes (p = 0.0058, and age (p = 0.0102 were independent predictor factors for survival. Use of digitalis and diuretics, together with previous angina, also influenced survival (p = 0.0092, as well as male gender, older patients, and diabetes together (p = 0.0420. Patients with AMI after prior CABS had smaller infarct, but more reinfarction, reoperation, heart failure, and angina. Previous angina, diabetes, and age, independently, as well as use of digitalis and diuretics together with angina, and male gender, older patients, and diabetes together, influenced a worse survival rate in these patients.

  19. Study on the hardening mechanism of cement asphalt binder

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    The hydration and hardening mechanism of cement asphalt binder(CAB) was studied.The early hydration process,hydration products and paste microstructure of CAB made by Portland cement and anionic asphalt emulsion were investigated by calorimetry,X-ray diffraction,and environmental scanning electron microscopy.The early hydration process of CAB can be characterized as 5 stages similar to those of Portland cement.There is no chemical reaction detected between cement and asphalt,hence no new hydration products other than those of Portland cement are produced.The hardening of CAB begins with the hydration of cement.When the hydration of cement comes into the acceleration period and its exothermic rate comes to the maximum,the coalescence of asphalt particles in asphalt emulsion is triggered.In the hardened system of CAB,it was found that the hydration products of cement form the skeleton and are covered by the continuous asphalt film.They formed an interpenetrating network system.The emulsifiers in the asphalt emulsion may retard the hydration process of cement.

    As citrus is progressively contributing to horticultural production, wealth and economy of a country, it is necessary to understand the factors impacting citrus production. Gummosis is one of the most serious diseases causing considerable loss of overall citrus production and yield quality. A qualitative and quantitative analysis of citrus leaf biochemical properties are necessary to monitor the crop health, disease /pest stress and production. Total leaf chlorophyll content (Cab) represents one of the key biochemical factors which contributes in water, carbon, and energy exchange processes. Photosynthesis process in citrus will be disturbed as gummosis disease life cycle progresses. It is important to study Cab to evaluate the photosynthesis rate and disease stress. In this study the potential of Radiative Transfer (RT) PROSPECT model to retrieve Cab in citrus orchards was undertaken at different sites. The main goal is to evaluate the relationship between Cab and gummosis disease stress for citrus at various phenological stages. Inversion of PROSPECT model on measured hyperspectral data is carried out to extract the leaf level parameters influencing the disease. This model was inverted with the ground truth hyperspectral reading. The testing was separately initiated for healthy and infected plant leaves. This can lead to understand the disease stress on citrus leaves. For accuracy, raw spectra are filtered and processed which is an input parameter for Inversion PROSPECT model. Here, retrieved Cab content was correlated with gummosis disease stress in terms of oozing with R2 = 0.6021 and RMSE= 0.481272.

  1. Purification and immunochemical characterization of the cytoplasmic androgen-binding protein of rat liver

    International Nuclear Information System (INIS)

    The cytoplasmic androgen-binding (CAB) protein of the male rate liver has been implicated to play a role in the androgen-dependent regulation of α2u-globulin synthesis. The liver of the adult male rat contains about 50 fmol of specific high-affinity androgen-binding activity per milligram of total cytosolic protein. Photoaffinity labeling with [3H]R-1881 followed by SDS-polyacrylamide gel electrophoresis and autoradiography shows that the CAB is a 31-kilodalton protein. By means of DEAE-cellulose chromatography and preparative SCS-polyacrylamide gel electrophoresis, the authors have purified the CAB protein to electrophoretic homogeneity and have raised polyclonal rabbit antiserum that is monospecific to this protein. In the sucrose density gradient, the antiserum reacted with the androgen-binding component of the male liver cytosol prelabeled with tritiated dihydrotestosterone. Western blot analysis of the liver cytosol showed that the antiserum recognizes only the 31-kDa androgen-binding component. Such immunoblotting also showed that unlike the young adult, the androgen-insensitive states during prepuberty and senescence are associated with a marked reduction in the hepatic concentration of the immunoreactive CAB protein. No immunochemical cross-reactivity between CAB and another androgen-binding component of Mr 29K was observed. The latter finding favors the possibility that 31- and 29-kDa androgen-binding components may have distinct sequence structure

    The objective of this study was to investigate the relationship of medial temporal lobe and posterior cingulate cortex (PCC) volumetrics as well as fractional anisotropy of the cingulum angular bundle (CAB) and the cingulum cingulate gyrus (CCG) bundle to performance on measures of verbal memory in non-demented older adults. The participants were 100 non-demented adults over the age of 70 years from the Einstein Aging Study. Volumetric data were estimated from T1-weighted images. The entire cingulum was reconstructed using diffusion tensor MRI and probabilistic tractography. Association between verbal episodic memory and MRI measures including volume of hippocampus (HIP), entorhinal cortex (ERC), PCC and fractional anisotropy of CAB and CCG bundle were modeled using linear regression. Relationships between atrophy of these structures and regional cingulum fractional anisotropy were also explored. Decreased HIP volume on the left and decreased fractional anisotropy of left CAB were associated with lower memory performance. Volume changes in ERC, PCC and CCG disruption were not associated with memory performance. In regression models, left HIP volume and left CAB-FA were each independently associated with episodic memory. The results suggest that microstructural changes in the left CAB and decreased left HIP volume independently influence episodic memory performance in older adults without dementia. The importance of these findings in age and illness-related memory decline require additional exploration. PMID:26424564

    In hospitalized adults acute uncomplicated cystitis (AUC) and catheter associated bacteriuria (CAB) may be treated with oral antibiotics. With AUC or CAB due to extended spectrum ß-lactamase (ESBL) + Gram negative bacilli (GNB) physicians often use intravenous therapy, e.g., ertapenem. We reviewed our recent experience in hospitalized adults with AUC and CAB treated with ertapenem. Therapeutic efficacy of ertapenem was assessed by decreased pyuria/bacteriuria, and elimination of the uropathogen. The effectiveness of ertapenem in the presence of renal insufficiency (CrCl ertapenem was highly effective in eliminating bacteriuria (TTNC 3 days) in patients with decreased renal function and alkaline urinary pH. We reviewed 45 hospitalized adults with AUC or CAB to determine if renal insufficiency and or alkaline urinary pH affected ertapenem efficacy. In the 33 adult hospitalized patients with AUC and 12 with CAB, we found that ertapenem was consistently effective in eliminating the GNB bacteriuria. In hospitalized adults, the presence of renal insufficiency and acid urine, bacteriuria was eliminated in  3 days which has not been previously reported. PMID:26873378

    In the United States, intercity long-haul trucks idle approximately 1,800 hrs annually for sleeper cab hotel loads, consuming 838 million gallons of diesel fuel per year. The objective of the CoolCab project is to work closely with industry to design efficient thermal management systems for long-haul trucks that keep the cab comfortable with minimized engine idling. Truck engine idling isprimarily done to heat or cool the cab/sleeper, keep the fuel warm in cold weather, and keep the engine warm for cold temperature startup. Reducing the thermal load on the cab/sleeper will decrease air conditioning system requirements, improve efficiency, and help reduce fuel use. CoolCalc is an easy-to-use, simplified, physics-based HVAC load estimation tool that requires no meshing, hasflexible geometry, excludes unnecessary detail, and is less time-intensive than more detailed computer-aided engineering modeling approaches. It is intended for rapid trade-off studies, technology impact estimation, and preliminary HVAC sizing design and to complement more detailed and expensive CAE tools by exploring and identifying regions of interest in the design space. This paper describesthe CoolCalc tool, provides outdoor long-haul truck thermal testing results, shows validation using these test results, and discusses future applications of the tool.

    Full Text Available The use of transparent polymers as an alternative to glass has become widespread. However, the direct exposure of these materials to climatic conditions of sunlight and heat decrease the lifetime cost of these products. The aim of this study was to minimize the harm caused by ultraviolet (UV radiation exposure to transparent poly(methylmethacrylate (PMMA, which usually leads to changes in the physical and chemical properties of these materials and reduced performance. This was achieved using environmentally friendly cellulose acetate butyrate (CAB. The optical, morphological, and thermal properties of CAB blended with transparent PMMA was studied using UV-VIS spectrophotometry, scanning electron microscopy, X-ray diffraction, dynamic mechanical analysis, and thermal gravimetric analysis. The results show that CAB was able to reduce the effects of UV radiation by making PMMA more transparent to UV light, thereby preventing the negative effects of trapped radiation within the compositional structure, while maintaining the amorphous structure of the blend. The results also show that CAB blended with PMMA led to some properties commensurate with the requirements of research in terms of a slight increase in the value of the modulus and the glass transition temperature for the PMMA/CAB blend.

    In hospitalized adults acute uncomplicated cystitis (AUC) and catheter associated bacteriuria (CAB) may be treated with oral antibiotics. With AUC or CAB due to extended spectrum ß-lactamase (ESBL) + Gram negative bacilli (GNB) physicians often use intravenous therapy, e.g., ertapenem. We reviewed our recent experience in hospitalized adults with AUC and CAB treated with ertapenem. Therapeutic efficacy of ertapenem was assessed by decreased pyuria/bacteriuria, and elimination of the uropathogen. The effectiveness of ertapenem in the presence of renal insufficiency (CrCl 3 days) in patients with decreased renal function and alkaline urinary pH. We reviewed 45 hospitalized adults with AUC or CAB to determine if renal insufficiency and or alkaline urinary pH affected ertapenem efficacy. In the 33 adult hospitalized patients with AUC and 12 with CAB, we found that ertapenem was consistently effective in eliminating the GNB bacteriuria. In hospitalized adults, the presence of renal insufficiency and acid urine, bacteriuria was eliminated in i.e., time to negative cultures (TTNC) was prolonged, i.e., > 3 days which has not been previously reported.

  7. The predatory bacterium Bdellovibrio bacteriovorus aspartyl-tRNA synthetase recognizes tRNAAsn as a substrate.

    Directory of Open Access Journals (Sweden)

    Ariel Alperstein

    Full Text Available The predatory bacterium Bdellovibrio bacteriovorus preys on other Gram-negative bacteria and was predicted to be an asparagine auxotroph. However, despite encoding asparaginyl-tRNA synthetase and glutaminyl-tRNA synthetase, B. bacteriovorus also contains the amidotransferase GatCAB. Deinococcus radiodurans, and Thermus thermophilus also encode both of these aminoacyl-tRNA synthetases with GatCAB. Both also code for a second aspartyl-tRNA synthetase and use the additional aspartyl-tRNA synthetase with GatCAB to synthesize asparagine on tRNAAsn. Unlike those two bacteria, B. bacteriovorus encodes only one aspartyl-tRNA synthetase. Here we demonstrate the lone B. bacteriovorus aspartyl-tRNA synthetase catalyzes aspartyl-tRNAAsn formation that GatCAB can then amidate to asparaginyl-tRNAAsn. This non-discriminating aspartyl-tRNA synthetase with GatCAB thus provides B. bacteriovorus a second route for Asn-tRNAAsn formation with the asparagine synthesized in a tRNA-dependent manner. Thus, in contrast to a previous prediction, B. bacteriovorus codes for a biosynthetic route for asparagine. Analysis of bacterial genomes suggests a significant number of other bacteria may also code for both routes for Asn-tRNAAsn synthesis with only a limited number encoding a second aspartyl-tRNA synthetase.

    2016-06-01

    5-Fluorocytosine (FC) is a high-dose antifungal drug that challenges the development of a tablet product due to poor solid-state stability and tabletability. Using 2 pharmaceutically acceptable conjugate acid base (CAB) cocrystals of FC with HCl and acesulfame, we have developed commercially viable high loading FC tablets. The tablets were prepared by direct compression using nano-coated microcrystalline cellulose Avicel PH105 as a tablet binder, which provided both excellent tabletability and good flowability. Commercial manufacturability of formulations based on both CAB cocrystals was verified on a compaction simulator. The results from an expedited friability study were used to set the compaction force, which yielded tablets with sufficient mechanical strength and rapid tablet disintegration. This work demonstrates the potential value of CAB cocrystals in drug product development. PMID:27238493

    2011-05-01

    Full Text Available Community-based participatory research (CBPR is a paradigm to study and reduce disparities in health outcomes related to chronic disease. Community advisory boards (CABs commonly formalize the academic–community partnerships that guide CBPR by providing a mechanism for community members to have representation in research activities. Researchers and funding agencies increasingly recognize the value of the community’s contribution to research and acknowledge that community advisory boards are a key component of successful CBPR projects. In this article, we describe the best processes for forming, operating, and maintaining CABs for CBPR. We synthesize the literature and offer our professional experiences to guide formation, operation, and maintenance of CABs.

  11. Diagnosis and medical treatment of prolactinomas

    International Nuclear Information System (INIS)

    The first-line treatment of prolactinomas is medical therapy with dopamine receptor agonists. Bromocriptine (BC) has been used over the past 30 years, while cabergoline (CAB) is increasingly used in recent years because of its enhanced efficacy and better tolerability. Cabergoline is highly effective in normalizing elevated prolactin, recovering hypogonadism, and achieving a successful pregnancy in patients with tumoral and non-tumoral hyperprolactinemia. Also, CAB has a greater ability to shrink prolactinomas (PRLomas) than BC and often extinguishes them. Regarding the diagnosis, it requires demonstrating hyperprolactinemia on at least two separate occasions, excluding other causes of hyperprolactinemia than PRLomas, and detecting pituitary tumor on magnetic resonance imaging. Final diagnosis in non-operated cases is made empirically by attaining unequivocal tumor shrinkage or disappearance with CAB treatment. (author)

    Background Bloodstream infections (BSls) remain a major cause of morbidity and mortality in patients undergoing surgery.This study aimed at elucidating the clinical characteristics of community-acquired BSls (CABs) and nosocomial BSls (nBSls) in patients admitted to the surgical wards of a teaching hospital in Beijing,China.Methods This cross-sectional study compared 191 episodes of BSls in 4074 patients admitted to the surgical wards between January 2008 and December 2011.Cases of BSls were classified as CABs or nBSls,and the characteristics,relevant treatments,and outcomes of CABs and nBSls were compared.Results Of the 191 BSls,52 (27.2%) and 139 (72.8%) were CABs and nBSls,respectively.Eschedchia coli,coagulasenegative staphylococci,and Klebsiella spp,were the most frequently isolated microorganisms.There were significant differences between CABs and nBSls with respect to the use of hormonal drugs,ventilation,acute physiology and chronic health evaluation (APACHE) Ⅱ and American Society of Anesthesiologists scores,and prevalence of cancer (P <0.05).Empirical antibacterial therapy did not decrease the crude mortality,but multivariate analysis showed that high APACHE Ⅱ was independently associated with a risk of mortality (odds ratio =0.97,95% confidence interval:0.93-1.02 for APACHE Ⅱ).Conclusions We found significant differences in the clinical characteristics of surgical patients with CABs and nBSls.The outcome of patients seems to be related to high APACHE Ⅱ scores.

  13. Insights into tRNA-Dependent Amidotransferase Evolution and Catalysis from the Structure of the Aquifex aeolicus Enzyme

    Many bacteria form Gln-tRNA{sup Gln} and Asn-tRNA{sup ASN} by conversion of the misacylated Glu-tRNA{sup Gln} and Asp-tRNA{sup ASN} species catalyzed by the GatCAB amidotransferase in the presence of ATP and an amide donor (glutamine or asparagine). Here, we report the crystal structures of GatCAB from the hyperthermophilic bacterium Aquifex aeolicus, complexed with glutamine, asparagine, aspartate, ADP, or ATP. In contrast to the Staphylococcus aureus GatCAB, the A. aeolicus enzyme formed acyl-enzyme intermediates with either glutamine or asparagine, in line with the equally facile use by the amidotransferase of these amino acids as amide donors in the transamidation reaction. A water-filled ammonia channel is open throughout the length of the A. aeolicus GatCAB from the GatA active site to the synthetase catalytic pocket in the B-subunit. A non-catalytic Zn{sup 2+} site in the A. aeolicus GatB stabilizes subunit contacts and the ammonia channel. Judged from sequence conservation in the known GatCAB sequences, the Zn{sup 2+} binding motif was likely present in the primordial GatB/E, but became lost in certain lineages (e.g., S. aureus GatB). Two divalent metal binding sites, one permanent and the other transient, are present in the catalytic pocket of the A. aeolicus GatB. The two sites enable GatCAB to first phosphorylate the misacylated tRNA substrate and then amidate the activated intermediate to form the cognate products, Gln-tRNA{sup Gln} or Asn-tRNA{sup ASN}.

    It is not known whether computerized cognitive assessments, like the CogState battery, are sensitive to preclinical cognitive changes or pathology in people at risk for Alzheimer’s disease (AD). In 469 late middle-aged participants from the Wisconsin Registry for Alzheimer’s Prevention (mean age 63.8±7 years at testing; 67% female; 39% APOE4+), we examined relationships between a CogState abbreviated battery (CAB) of seven tests and demographic characteristics, traditional paper-based neuropsychological tests as well as a composite cognitive impairment index, cognitive impairment status (determined by consensus review); and biomarkers for amyloid and tau (CSF phosphorylated-tau/Aβ42 and global PET-PiB burden) and neural injury (CSF neurofilament light protein). CSF and PET-PiB were collected in n=71 and n=91 participants, respectively, approximately four years prior to CAB testing. For comparison, we examined three traditional tests of delayed memory in parallel. Similar to studies in older samples, the CAB was less influenced by demographic factors than traditional tests. CAB tests were generally correlated with most paper-based cognitive tests examined and mapped onto the same cognitive domains. Greater composite cognitive impairment index was associated with worse performance on all CAB tests. Cognitively impaired participants performed significantly worse compared to normal controls on all but one CAB test. Poorer One Card Learning test performance was associated with higher levels of CSF phosphorylated-tau/Aβ42. These results support the use of the CogState battery as measures of early cognitive impairment in studies of people at risk for AD. PMID:27589532

    Protective antigen (PA), a key component of anthrax toxin, mediates the entry of lethal factor (LF) or edema factor (EF) through a membranal pore into target cells. We have previously reported the isolation and chimerization of cAb29, an anti-PA monoclonal antibody that effectively neutralizes anthrax toxin in an unknown mechanism. The aim of this study was to elucidate the neutralizing mechanism of this antibody in vitro and to test its ability to confer post-exposure protection against anthrax in vivo. By systematic evaluation of the steps taking place during the PA-based intoxication process, we found that cAb29 did not interfere with the initial steps of intoxication, namely its ability to bind to the anthrax receptor, the consecutive proteolytic cleavage to PA(63), oligomerization, prepore formation, or LF binding. However, the binding of cAb29 to the prepore prevented its pH-triggered transition to the transmembranal pore, thus preventing the last step of intoxication, i.e. the translocation of LF/EF into the cell. Epitope mapping, using a phage display peptide library, revealed that cAb29 binds the 2α(1) loop in domain 2 of PA, a loop that undergoes major conformational changes during pore formation. In vivo, we found that 100% of anthrax-infected rabbits survived when treated with cAb29 12 h after exposure. In conclusion, these experiments demonstrate that cAb29 exerts its potent neutralizing activity in a unique manner by blocking the prepore-to-pore conversion process. PMID:22869370

    By applying a combination of light transitions, uncouplers, and inhibitors of photosynthetic electron transport inhibitors we modulate the redox poise of many components in the plastid and examine the pattern of expression of cab1 gene. This gene encodes the major light harvesting protein that services photosystem II. While our results have confirmed our own previous finding that light intensity regulation of cab1 gene expression is signaled by the redox state of the PQ pool, we have also identified additional sensor(s) located in the PET chain.

    Protein phosphatase Z (Ppz) is a fungus specific enzyme that regulates cell wall integrity, cation homeostasis and oxidative stress response. Work on Saccharomyces cerevisiae has shown that the enzyme is inhibited by Hal3/Vhs3 moonlighting proteins that together with Cab3 constitute the essential phosphopantothenoylcysteine decarboxylase (PPCDC) enzyme. In Candida albicans CaPpz1 is also involved in the morphological changes and infectiveness of this opportunistic human pathogen. To reveal the CaPpz1 regulatory context we searched the C. albicans database and identified two genes that, based on the structure of their S. cerevisiae counterparts, were termed CaHal3 and CaCab3. By pull down analysis and phosphatase assays we demonstrated that both of the bacterially expressed recombinant proteins were able to bind and inhibit CaPpz1 as well as its C-terminal catalytic domain (CaPpz1-Cter) with comparable efficiency. The binding and inhibition were always more pronounced with CaPpz1-Cter, indicating a protective effect against inhibition by the N-terminal domain in the full length protein. The functions of the C. albicans proteins were tested by their overexpression in S. cerevisiae. Contrary to expectations we found that only CaCab3 and not CaHal3 rescued the phenotypic traits that are related to phosphatase inhibition by ScHal3, such as tolerance to LiCl or hygromycin B, requirement for external K+ concentrations, or growth in a MAP kinase deficient slt2 background. On the other hand, both of the Candida proteins turned out to be essential PPCDC components and behaved as their S. cerevisiae counterparts: expression of CaCab3 and CaHal3 rescued the cab3 and hal3 vhs3 S. cerevisiae mutations, respectively. Thus, both CaHal3 and CaCab3 retained the PPCDC related functions and have the potential for CaPpz1 inhibition in vitro. The fact that only CaCab3 exhibits its phosphatase regulatory potential in vivo suggests that in C. albicans CaCab3, but not CaHal3, acts as a

The promoter can drive the expression of prosystemin (PS) and GFP fusion vector, then get the transgenic plants. The plasmids were transformed into Arabidopsis by using Agrobacterium tumefaciens-mediated method. The semi-quantitative RT-PCR method and laser scanning confocal microscope (LSCM) were used to observe the expression and subcellular localization of promoter-driven PS-GFP.Using Arabidopsis genomic DNA as a template, the sequence of promoter cab2 was amplified by high fidelity PCR enzyme, then connected it with the PS and GFP fusion vector (SlPS). The LSCM observation showed that the gene driven by this promoter was normally expressed and located in the cytoplasm. The cab2 promoter was cloned, which can drive the expression and localization of the PS and GFP fusion protein.%克隆地上部特异表达的启动子--cab2(chlorophyll a/b binding protein 2,cab2)基因的启动子,构建该启动子驱动下的番茄原系统素(Prosystemin;PS)与GFP融合的植物表达载体并获得转基因植株.利用农杆菌介导法转化拟南芥,通过RT-PCR的方法及激光共聚焦显微镜观察启动子驱动PS-GFP的表达及其亚细胞定位.以拟南芥基因组为模板,利用高保真聚合酶获得了cab2启动子的目的片段,并将其与接GFP的番茄原系统素载体(SlPS)融合,激光共聚焦显微镜观察表明,该启动子驱动的基因正常表达和并定位于细胞质中.克隆获得到了cab2基因的启动子,该启动子能够驱动番茄原系统素和GFP的融合蛋白正常表达和定位.

  1. Optimized Hyper Beamforming of Linear Antenna Arrays Using Collective Animal Behaviour

    Directory of Open Access Journals (Sweden)

    Gopi Ram

    2013-01-01

    Full Text Available A novel optimization technique which is developed on mimicking the collective animal behaviour (CAB is applied for the optimal design of hyper beamforming of linear antenna arrays. Hyper beamforming is based on sum and difference beam patterns of the array, each raised to the power of a hyperbeam exponent parameter. The optimized hyperbeam is achieved by optimization of current excitation weights and uniform interelement spacing. As compared to conventional hyper beamforming of linear antenna array, real coded genetic algorithm (RGA, particle swarm optimization (PSO, and differential evolution (DE applied to the hyper beam of the same array can achieve reduction in sidelobe level (SLL and same or less first null beam width (FNBW, keeping the same value of hyperbeam exponent. Again, further reductions of sidelobe level (SLL and first null beam width (FNBW have been achieved by the proposed collective animal behaviour (CAB algorithm. CAB finds near global optimal solution unlike RGA, PSO, and DE in the present problem. The above comparative optimization is illustrated through 10-, 14-, and 20-element linear antenna arrays to establish the optimization efficacy of CAB.

  2. Inhibition of quorum sensing regulated biofilm formation in Serratia marcescens causing nosocomial infections.

    Science.gov (United States)

    Bakkiyaraj, Dhamodharan; Sivasankar, Chandran; Pandian, Shunmugiah Karutha

    2012-05-01

    Serratia marcescens is an opportunistic pathogen causing severe urinary tract infections in hospitalized individuals. Infections of S. marcescens are of great concern because of its increasing resistance towards conventional antibiotics. Quorum sensing (QS)-a cell to cell communication-system of S. marcescens acts as a global regulator of almost all the virulence factors and majorly its biofilm formation. Since, the QS system of S. marcescens directly accords to its pathogenesis, targeting QS system will provide an improved strategy to combat drug resistant pathogens. In the present study, QS system of S. marcescens has been used as target and its inhibition has been studied upon exposure to bioactives from coral associated bacteria (CAB). This study also emphasises the potential of CAB in producing bioactive agents with anti-QS and antibiofilm properties. Two CAB isolates CAB 23 and 41 have shown to inhibit biofilm formation and the production of QS dependent virulence factors like prodigiosin, protease, lipase and swarming motility. The study, on the whole explicates the potential of QS system as a target to treat drug resistant bacterial infections. PMID:22487181

    Wu, Ling; Liu, Xiang-Nan; Zhou, Bo-Tian; Liu, Chuan-Hao; Li, Lu-Feng

    2012-12-01

    This study analyzed the sensitivities of three vegetation biochemical parameters [chlorophyll content (Cab), leaf water content (Cw), and leaf area index (LAI)] to the changes of canopy reflectance, with the effects of each parameter on the wavelength regions of canopy reflectance considered, and selected three vegetation indices as the optimization comparison targets of cost function. Then, the Cab, Cw, and LAI were estimated, based on the particle swarm optimization algorithm and PROSPECT + SAIL model. The results showed that retrieval efficiency with vegetation indices as the optimization comparison targets of cost function was better than that with all spectral reflectance. The correlation coefficients (R2) between the measured and estimated values of Cab, Cw, and LAI were 90.8%, 95.7%, and 99.7%, and the root mean square errors of Cab, Cw, and LAI were 4.73 microg x cm(-2), 0.001 g x cm(-2), and 0.08, respectively. It was suggested that to adopt vegetation indices as the optimization comparison targets of cost function could effectively improve the efficiency and precision of the retrieval of biochemical parameters based on PROSPECT + SAIL model.

  12. Antibiofilm activity of coral-associated bacteria against different clinical M serotypes of Streptococcus pyogenes.

    Streptococcus pyogenes is the frequent cause of purulent infections in humans. Formation of a biofilm is one of the important aspects of its pathogenicity. Streptococcus pyogenes biofilm communities tend to exhibit significant tolerance to antimicrobial challenge during infections. Exploring novel targets against biofilm-forming pathogens is therefore an important alternative treatment measure. We attempted to screen marine bacteria, especially coral-associated bacteria (CAB), for antibiofilm activity against streptococcal biofilm formation. The bacterial biofilms were quantified by crystal violet staining. Of 43 CAB isolates, nine clearly demonstrated antibiofilm activity. At biofilm inhibitory concentrations (BIC), biofilm formation was reduced up to 80%, and sub-BIC (0.5 and 0.25 BIC) significantly reduced biofilm formation by up to 60% and 40-60%, respectively. Extracts of Bacillus horikoshii (E6) displayed efficient antibiofilm activity. As quorum sensing (QS) and cell surface hydrophobicity (CSH) are crucial factors for biofilm formation in S. pyogenes, the CAB were further screened for QS inhibition properties and CSH reduction properties. This study reveals the antibiofilm and QS inhibition property of CAB. PMID:19845763

    Ruth Alfaro-Cuevas-Villanueva

    2014-01-01

    Full Text Available The sorption of cadmium (Cd and lead (Pb by calcium alginate beads (CAB from aqueous solutions in batch systems was investigated. The kinetic and thermodynamic parameters, as well as the sorption capacities of CAB in each system at different temperatures, were evaluated. The rate of sorption for both metals was rapid in the first 10 minutes and reached a maximum in 50 minutes. Sorption kinetic data were fitted to Lagergren, pseudo-second-order and Elovich models and it was found that the second-order kinetic model describes these data for the two metals; comparing kinetic parameters for Cd and Pb sorption a higher kinetic rate (K2 for Pb was observed, indicating that the interaction between lead cations and alginate beads was faster than for cadmium. Similarly, isotherm data were fitted to different models reported in literature and it was found that the Langmuir-Freundlich (L-F and Dubinin-Radushkevich (D-R models describe the isotherms in all cases. CAB sorption capacity for cadmium was 27.4 mg/g and 150.4 mg/g for lead, at 25°C. Sorption capacities of Cd and Pb increase as temperature rises. According to the thermodynamic parameters, the cadmium and lead adsorption process was spontaneous and endothermic. It was also found that pH has an important effect on the adsorption of these metals by CAB, as more were removed at pH values between 6 and 7.

    Agran, P; Winn, D; Anderson, C

    1994-11-01

    Transporting passengers in the cargo area of pickup trucks is a public health safety issue in the United States. Our study compared crashes involving passengers in the cargo area with those involving passengers in the cab. We obtained data for all injury events of pickup occupants for 1990 from the California Highway Patrol. A total of 702 traffic reports coded as having passengers riding in pickup truck beds involved 1,685 passengers in the cargo area and 865 in the cab. Significantly more events involving passengers in the cargo area occurred in summer in rural areas and were noncollisions than did events with only cab passengers. Crashes with passengers in the cargo area resulted in death in 5% of passengers. Of the drivers, 81% were male and 22% were younger than 20 years. Among the 1,685 passengers in the cargo area, 65% were male, 36% were younger than 15 years, and 30% were ages 15 to 19 years. Passengers in the cargo area were more frequently ejected and more seriously injured than their counterparts in the cab. Legislation to restrict travel in truck beds and the design of restraints for this area are some measures that may reduce the risk of injury. PMID:7810125

  3. The Evolution of Light Stress Proteins in Photosynthetic Organisms

    Directory of Open Access Journals (Sweden)

    Iwona Adamska

    2006-04-01

    Full Text Available The Elip (early light-inducible protein family in pro- and eukaryotic photosynthetic organisms consists of more than 100 different stress proteins. These proteins accumulate in photosynthetic membranes in response to light stress and have photoprotective functions. At the amino acid level, members of the Elip family are closely related to light-harvesting chlorophyll a/b-binding (Cab antenna proteins of photosystem I and II, present in higher plants and some algae. Based on their predicted secondary structure, members of the Elip family are divided into three groups: (a one-helix Hlips (high light-induced proteins, also called Scps (small Cab-like proteins or Ohps (one-helix proteins; (b two-helix Seps (stress-enhanced proteins; and (c three-helix Elips and related proteins. Despite having different physiological functions it is believed that eukaryotic three-helix Cab proteins evolved from the prokaryotic Hlips through a series of duplications and fusions. In this review we analyse the occurrence of Elip family members in various photosynthetic prokaryotic and eukaryotic organisms and discuss their evolutionary relationship with Cab proteins.

    Houborg, R.; Anderson, M. C.; Kustas, W. P.; Daughtry, C.

    2009-05-01

    Chlorophylls absorb photosynthetically active radiation and thus function as vital pigments for photosynthesis, which makes leaf chlorophyll content (Cab) useful for monitoring vegetation productivity and an important indicator of the overall plant physiological condition. This study investigates the utility of spatiotemporal Cab estimates for optimizing CO2 fluxes simulated by a coupled water and carbon cycle model that implements an analytical, light-use-efficiency (LUE) based model of canopy resistance within a two-source energy balance scheme. The LUE model component computes canopy-scale carbon assimilation and transpiration fluxes and incorporates LUE modifications from a nominal value (LUEn) in response to variations in humidity, CO2 concentration, temperature (soil and air), wind speed, and direct beam vs. diffuse light composition. LUEn is typically indexed by vegetation class assuming conservation of LUE for major vegetation types under unstressed environmental conditions. LUEn is highly influential in modifying CO2 assimilation rates and may need further adjustment on a daily timescale to accommodate changes in plant phenology, physiological condition and nutrient status. Day to day variations in LUEn was assessed for a heterogeneous corn crop field in Maryland, U.S.A. through model calibration with eddy covariance CO2 flux tower observations. The optimized daily LUEn values were then compared to estimates of Cab integrated from gridded Cab maps as a weighted sum over the tower flux source area. A continuous spatiotemporal Cab record (spanning the period from 3 weeks after leaf emergence through corn tasseling and silking and a stage of leaf senescence) was generated by fusing extensive in-situ measurements with retrievals generated from 1 m resolution aircraft imagery using an integrated radiative transfer modeling tool (validated to 10% accuracy). Extreme environmental conditions imposed highly variable degrees of plant stress across the field due to

    Diagnosis of brucellosis basically depends on blood and/or bone marrow culture and demonstration of high titer specific antibody or seroconversion in serum. In routine serological diagnosis of the disease, after screening with Rose Bengal test, the positive samples are studied with standart tube agglutination (STA) test with serial dilutions. However false negative results can be seen in STA test due to the existence of blocking antibodies, this test should be verified with Coombs anti-Brucella (CAB) or immunocapture agglutination (ICA) tests. In recent years Brucella Coombs gel test (ODAK Brucella Coombs Gel Test, Toprak Medikal, Turkey) developed in our country, was available as a new and rapid agglutination based method. The test is performed in vials that contain Coombs antibodies within gel matrix and results are evaluated visually within two hours.The aim of this study was to compare the efficacy of Brucella Coombs gel test (BCGT) with STA, CAB and ICA methods in serological diagnosis of brucellosis. A total of 100 serum samples with suspected brucellosis sent to our laboratory between January 2012-August 2013 in which 31 high positive (≥ 1/160), 23 low positive (≤ 1/80) and 46 negative samples diagnosed with CAB test (Seromed, Turkey) were included in the study. All the samples were studied using titrations with STA (Seromed, Turkey), ICA (Vircell, Spain) and BCGT (Islab, Turkey) methods. With STA, CAB and BCGT tests ≥ 1/160, with ICA test ≥ 1/320 were accepted as positive titers. The correlation between the tests were evaluated with Cohen's kappa (κ) analysis. In our study, seven of the samples yielded positive results with STA, 30 with ICA, and 32 with BCGT. The number of the sera which yielded positive results with all three methods was 28. Two samples positive with CAB and BCGT resulted low titer/negative with ICA, one sample positive with ICA and BCGT resulted low titer/negative with CAB, and one low titer/negative sample with CAB and BCGT

    The drilling and operation of gas/petroleum exploratory wells and the operations of natural gas and petroleum production wells generate a number of waste materials that are usually stored and/or processed at the drilling/operations site. Contaminated soils result from drilling operations, production operations, and pipeline breaks or leaks where crude oil and petroleum products are released into the surrounding soil or sediments. In many cases, intrinsic biochemical remediation of these contaminated soils is either not effective or is too slow to be an acceptable approach. This project targeted petroleum-impacted soil and other wastes, such as soil contaminated by: accidental release of petroleum and natural gas-associated organic wastes from pipelines or during transport of crude oil or natural gas; production wastes (such as produced waters, and/or fuels or product gas). Our research evaluated the process designated Chemically-Accelerated Biotreatment (CAB) that can be applied to remediate contaminated matrices, either on-site or in situ. The Gas Technology Institute (GTI) had previously developed a form of CAB for the remediation of hydrocarbons and metals at Manufactured Gas Plant (MGP) sites and this research project expanded its application into Exploration and Production (E&P) sites. The CAB treatment was developed in this project using risk-based endpoints, a.k.a. environmentally acceptable endpoints (EAE) as the treatment goal. This goal was evaluated, compared, and correlated to traditional analytical methods (Gas Chromatography (GC), High Precision Liquid Chromatography (HPLC), or Gas Chromatography-Mass Spectrometry (CGMS)). This project proved that CAB can be applied to remediate E&P contaminated soils to EAE, i.e. those concentrations of chemical contaminants in soil below which there is no adverse affect to human health or the environment.

    Since the start of its contract in 2008, the CH2M Hill Plateau Remediation Company (CH2M HILL) has demolished 25 buildings with concrete asbestos board (CAB) siding using mechanical means. While the asbestos contained in CAB siding is not friable in its manufactured form, concerns persist that mechanical methods of demolition have the potential to render the asbestos friable and airborne, therefore posing a health risk to demolition workers and the public. CH2M HILL's experience demonstrates that when carefully managed, mechanical demolition of CAB siding can be undertaken safely, successfully, and in compliance with regulatory requirements for the disposal of Class II Asbestos-Containing Material (ACM). While the number of buildings demolished at Hanford and the number of samples collected does not make a conclusive argument that CAB cannot be made friable with normal demolition techniques, it certainly provides a significant body of evidence for the success of the approach. Of course, there are many factors that affect how to demolish a structure and dispose of the waste. These factors will impact the success depending on each site. The most obvious factors which contribute to this success at Hanford are: 1. The availability of onsite waste disposal where the handling and cost of asbestos-containing waste is not much different than other potentially contaminated waste. Therefore, segregation of demolition debris from the potential asbestos contamination is not necessary from a debris handling or asbestos disposal aspect. 2. The space between structures is typically significant enough to allow for large exclusion zones. There are not many restrictions due to cohabitation issues or potential contamination of adjacent facilities. 3. The willingness of the regulators and client to understand the industrial safety issues associated with manual CAB removal. (authors)

  18. Electronic structures, mechanical and thermodynamic properties of cubic alkaline-earth hexaborides from first principles calculations

    International Nuclear Information System (INIS)

    Highlights: • The band gaps for CaB6, SrB6 and BaB6 depend sensitively on the values of lattice constant a and positional parameter z. • The order in elastic anisotropy is CaB6 > SrB6 > BaB6. • There are LO/TO splitting lines in the range of 5–10 THz at G point. - Abstract: The electronic structures, mechanical and thermodynamic properties of alkaline-earth hexaborides MB6 (M = Ca, Sr or Ba) are calculated from first principles using density functional theory combined with the quasi-harmonic approximation. These three alkaline-earth hexaborides are semiconductors with a slightly increased trend for their band gaps as M orders from Ca to Ba. Their band gaps depend sensitively on the values of lattice constant a and internal parameter z. The polycrystalline values of the elastic constants and bulk, shear and Young’s moduli are consistent with those determined experimentally. All alkaline-earth hexaborides have strongly anisotropic elastic properties in the order of CaB6 > SrB6 > BaB6. By using the phonon calculations, the thermodynamic properties are investigated. The obtained phonon dispersion relations for CaB6, SrB6, and BaB6 show similar features and there are LO/TO splitting lines in the range of 5–10 THz. Finally, the thermal conductivities of CaB6, SrB6 and BaB6 are evaluated via Clarke’s model and Cahill’s model

    The K East (KE) Basin facilities are located near the north end of the Hanford Site's 100 K area. The facilities were built in 1950 as part of the KE Reactor complex and constructed within 400 meters of the Columbia River, which is the largest river in the Pacific Northwest and by volume the fourth largest river in the United States. The basin, located adjacent to the reactor, was used for the underwater storage of irradiated nuclear fuel discharged from the reactor. The basin was covered by a superstructure comprising steel columns and beams, concrete, and cement asbestos board (CAB) siding. The project's mission was to complete demolition of the structure over the K East basin within six months of tumover from facility deactivation activities. The demolition project team implemented open-air demolition techniques to demolish the facility to slab-on-grade. Several innovative techniques were used to control contamination and maintain contamination control within the confines of the demolition exclusion zone. The techniques, which focused on a defense-in-depth approach, included spraying fixatives on interior and exterior surfaces before demolition began; applying fixatives; misting using a fine spray of water during demolition; and demolishing the facility systematically. Another innovation that aided demolition was to demolish the building with the non-friable CAB remaining in place. The CAB siding covered the exterior of the building, portions of the interior walls, and was an integral part of the multiple layered roof. The project evaluated the risks involved in removing the CAB material in a radiologically contaminated environment and determined that radiological dose rates and exposure to radiological contamination and industrial hazards would be significantly reduced by removing the CAB during demolition using heavy equipment.

    Full Text Available Pyridoxal 5'-phosphate (PLP, the active form of vitamin B6, has been implicated in preventing human pathologies, such as diabetes and cancer. However, the mechanisms underlying the beneficial effects of PLP are still unclear. Using Drosophila as a model system, we show that PLP deficiency, caused either by mutations in the pyridoxal kinase-coding gene (dPdxk or by vitamin B6 antagonists, results in chromosome aberrations (CABs. The CAB frequency in PLP-depleted cells was strongly enhanced by sucrose, glucose or fructose treatments, and dPdxk mutant cells consistently displayed higher glucose contents than their wild type counterparts, an effect that is at least in part a consequence of an acquired insulin resistance. Together, our results indicate that a high intracellular level of glucose has a dramatic clastogenic effect if combined with PLP deficiency. This is likely due to an elevated level of Advanced Glycation End-products (AGE formation. Treatment of dPdxk mutant cells with α-lipoic acid (ALA lowered both AGE formation and CAB frequency, suggesting a possible AGE-CAB cause-effect relationship. The clastogenic effect of glucose in PLP-depleted cells is evolutionarily conserved. RNAi-mediated silencing of PDXK in human cells or treatments with PLP inhibitors resulted in chromosome breakage, which was potentiated by glucose and reduced by ALA. These results suggest that patients with concomitant hyperglycemia and vitamin B6 deficiency may suffer chromosome damage. This might impact cancer risk, as CABs are a well-known tumorigenic factor.

    Methane (CH4) is the primary component of natural gas and has a larger global warming potential than CO2. Recent top-down studies based on observations showed CH4 emissions in California's South Coast Air Basin (SoCAB) were greater than those expected from population-apportioned bottom-up state inventories. In this study, we quantify CH4 emissions with an advanced mesoscale inverse modeling system at a resolution of 8 km × 8 km, using aircraft measurements in the SoCAB during the 2010 Nexus of Air Quality and Climate Change campaign to constrain the inversion. To simulate atmospheric transport, we use the FLEXible PARTicle-Weather Research and Forecasting (FLEXPART-WRF) Lagrangian particle dispersion model driven by three configurations of the Weather Research and Forecasting (WRF) mesoscale model. We determine surface fluxes of CH4 using a Bayesian least squares method in a four-dimensional inversion. Simulated CH4 concentrations with the posterior emission inventory achieve much better correlations with the measurements (R2 = 0.7) than using the prior inventory (U.S. Environmental Protection Agency's National Emission Inventory 2005, R2 = 0.5). The emission estimates for CH4 in the posterior, 46.3 ± 9.2 Mg CH4/h, are consistent with published observation-based estimates. Changes in the spatial distribution of CH4 emissions in the SoCAB between the prior and posterior inventories are discussed. Missing or underestimated emissions from dairies, the oil/gas system, and landfills in the SoCAB seem to explain the differences between the prior and posterior inventories. We estimate that dairies contributed 5.9 ± 1.7 Mg CH4/h and the two sectors of oil and gas industries (production and downstream) and landfills together contributed 39.6 ± 8.1 Mg CH4/h in the SoCAB.

    Aim: Peroxisome proliferator-activated receptor gamma (PPARy) is a therapeutic target for obesity, cancer and diabetes mellitus. In order to develop potent lead compounds for obesity treatment, we screened a natural product library for novel PPARy antagonists with inhibitory effects on adipocyte differentiation. Methods: Surface plasmon resonance (SPR) technology and cell-based transactivation assay were used to screen for PPARy antago-nists. To investigate the antagonistic mechanism of the active compound, we measured its effect on PPARy/RXRα heterodimerization and PPARy co-activator recruitment using yeast two-hybrid assay, Gal4/UAS cell-based assay and SPR based assay. The 3T3-L1 cell differentiation assay was used to evaluate the effect of the active compound on adipocyte differentiation. Results: A new thiophene-acetylene type of natural product, 7-chloroarctinone-b (CAB), isolated from the roots of Rhaponticum uniflo-rum, was discovered as a novel PPARγ antagonist capable of inhibiting rosiglitazone-induced PPARγ transcriptional activity. SPR analy-sis suggested that CAB bound tightly to PPARγ and considerably antagonized the potent PPARy agonist rosigtitazone-stimulated PPARγ-LBD/RXRα-LBD binding. Gal4/UAS and yeast two-hybrid assays were used to evaluate the antagonistic activity of CAB on rosiglitazone-induced recruitment of the coactivator for PPARy. CAB could efficiently antagonize both hormone and rosiglitazone-induced adipocyte differentiation in cell culture. Conclusion: CAB shows antagonistic activity to PPARγ and can block the adipocyte differentiation, indicating it may be of potential use as a lead therapeutic compound for obesity.

    Phytochelatins (PCs) are peptides that function in heavy-metal chelation and detoxification in plants and fungi. A recent study showed that PCs have the ability to undergo long-distance transport in a root-to-shoot direction in transgenic Arabidopsis (Arabidopsis thaliana). To determine whether long-distance transport of PCs can occur in the opposite direction, from shoots to roots, the wheat (Triticum aestivum) PC synthase (TaPCS1) gene was expressed under the control of a shoot-specific promoter (CAB2) in an Arabidopsis PC-deficient mutant, cad1-3 (CAB2TaPCS1/cad1-3). Analyses demonstrated that TaPCS1 is expressed only in shoots and that CAB2TaPCS1/cad1-3 lines complement the cadmium (Cd) and arsenic metal sensitivity of cad1-3 shoots. CAB2TaPCS1/cad1-3 plants exhibited higher Cd accumulation in roots and lower Cd accumulation in shoots compared to wild type. Fluorescence HPLC coupled to mass spectrometry analyses directly detected PC2 in the roots of CAB2:TaPCS1/cad1-3 but not in cad1-3 controls, suggesting that PC2 is transported over long distances in the shoot-to-root direction. In addition, wild-type shoot tissues were grafted onto PC synthase cad1-3 atpcs2-1 double loss-of-function mutant root tissues. An Arabidopsis grafting technique for mature plants was modified to obtain an 84% success rate, significantly greater than a previous rate of approximately 11%. Fluorescence HPLC-mass spectrometry showed the presence of PC2, PC3, and PC4 in the root tissue of grafts between wild-type shoots and cad1-3 atpcs2-1 double-mutant roots, demonstrating that PCs are transported over long distances from shoots to roots in Arabidopsis.

    Calcium hexaboride (CAB6) nanopowder was prepared by low temperature chemical reaction of CaCl2 and NaBH4. Xray powder diffraction pattern indicated the formation of CaB6 crystal, the field emission scanning dectron microscope (FESEM) image showed that CaB6 nanopowder was agglomerated with cubic crystals with grain size of ~ 80 nm. HRTEM photographs indicated that the nanoparticles were single-crystal corresponding to the FESEM and XRD results, and the CaB6 crystal consisted well crystallized CaB6 core and thin amorphous shell (4 ~ 5 nm). Fourier transform Infrared (FTIR) and Ultraviolet-Visible-Ncer Infrared (UV-VIS-NIS) spectra were investigated to characterize optical properties of CaB6 nanopowder, compared with micrometer CaB6 powders. Compared with the weak absorption bands of micron-powder, obvious Einstein shift and band broadening occurred in nanopowder spectrum, which was thought to be related to lattice expansion and nanometer effect. UV-VIS-NIS spectrum showed that CaB6 nanopowder could absorb ultraviolet rays and the absorption peaks exist blue shift of spectrum, compared with micron powder. In conclusion, CaB6 nanopowder showed absorbency within all the detected regions in FTIR and UV-VIS-NIS spectra, especially to the infrared.%采用CaCl2 and NaBH4为原料低温合成CaB6纳米粉末.X射线衍射结果表明生成了CaB6晶体.场发射扫描电镜(FESEM)观测到粉末由接近立方体的平均粒径为80nm的小晶粒组成,有轻微团聚现象.高分辨透射电镜(FIR-TEM)表明纳米颗粒为单晶,这一发现与XRD和FESEM的结果相对应,且观察到晶体是以结晶良好的CaB6为芯,外面包覆着厚约4~5 nm的非晶层.CaB6纳米粉末的光学性能是通过傅立叶红外光谱和紫外-可见-近红外光谱来表征的,同时做CaB6微米粉末的光谱用以比较.与微米粉末仅有微弱的吸收带相比,纳米粉末的光谱出现明显的宽化和红移现象,这与晶格膨胀和纳米效应有关.紫外-可

  10. Rapid, controllable and environmentally benign fabrication of thermoplastic nanofibers and applications

    Science.gov (United States)

    Wang, Dong

    In situ fibrillar and lamellar hybrid morphology was found in various immiscible polymer blends prepared by melt ram extrusion of cellulose acetate butyrate (CAB)/Thermoplastics at a weight ratio of 80 to 20. The formation process was analyzed and proposed. The presence of the elongational flow field determines the formation of the fibrils, and the improvement of the mixing efficiency can significantly reduce the dimensions of formed fibrils into the submicro- or nano-scale. With above results, continuous and uniform yarns of thermoplastic nanofibers were prepared via direct melt twin-screw extrusion, providing better mixing efficiency of immiscible blends of thermoplastic polymers with cellulose acetate butyrate (CAB), and subsequent extraction removal of CAB matrix. The thermoplastics which can be made into nanofibers include polyesters, polyolefins, thermoplastic polyurethane and functional copolymers, such as PE-co-GMA (Poly(Ethylene-co-Glycidyl Methacrylate)), PVA-co-PE (Poly(Vinyl Alcohol-co-Ethylene)). Ratios of thermoplastics to sacrificial CAB matrix, melt viscosity, and interfacial tensions affect formation of the nanofibers. Moreover, the crystal structures of isotactic polypropylene (iPP) nanofiber prepared were characterized with DSC and WAXD. To further demonstrate the size and shape controllability of the thermoplastic nanomaterials, polyethylene materials were selected and prepared into micro- or submicrospheres or nanofibers with different diameters and shapes by varying the composition ratio and modifying the interface properties via melt blending or extrusion of cellulose acetate butyrate (CAB)/LDPE melt blends and subsequent removal of the CAB. The surface structures of the LDPE micro- or submicrospheres and nanofibers were analyzed using SEM, FTIR-ATR spectroscopy, DSC and torque rheometer. The biotechnological applications of the thermoplastic nanofibers are also exploited. Poly(ethylene-co-glycidyl methacrylate) (PE-co-GMA) nanofibers with

    1997-12-01

    This study is the second phase in a combined analytical and experimental effort to characterize and improve the ride quality of the Department of Energy tractor/trailer. The discussion includes a brief overview of the finite element model of the vehicle and experimental road and modal test results. A novel system identification approach is used, employing both lab-based modal tests, and modal data derived using the Natural Excitation Technique (NExT), a scheme that utilizes the roadway surface as a natural forcing function. The use of a cab isolation system is investigated with the computer model for purposes of improving the ride quality of the vehicle. To validate these analytical predictions, an engineering prototype vehicle was developed, which included a cab isolation system, to experimentally assess ride quality. Ride quality improvements due to the addition of the isolation system are then assessed both experimentally and analytically, and the results are compared.

    We present a new framework for the description of macromolecules subject to confining geometries. The two main ingredients are a new computational method and the definition of a new molecular size parameter. The computational method, hereafter referred to the confinement analysis from bulk...... structures (CABS), allows the computation of equilibrium partition coefficients as a function of confinement size solely based on a single sampling of the configuration space of a macromolecule in bulk. Superior in computational speed to previous computational methods, CABS is capable of handling slits...... parameter for characterization of spatial confinement effects on macromolecules. Results for the equilibrium partition coefficient in the weak confinement regime depend only on the ratio ofR-s to the confinement size regardless of molecular details....

    This project was funded as part of the California Basin Study (CaBS), a DOE-funded regional program investigating production, cycling, transport, and fate of organic matter, chemical tracers, and pollutants in the Southern California Bight. The study area, adjacent to Los Angeles, was of programmatic interest due to its heavy concentration of energy-related activities, including offshore oil drilling and natural seeps, shipping, nuclear power facilities, and industrial and municipal ocean waste disposal. It was also of scientific interest because the wide continental margin in the region, pot-marked with natural sediment traps in the form of deep basins with restricted inputs and outputs, was ideal for integrating water-column and benthic studies and tracing the fates of in situ production and introduced pollutants. Our role in the CABS Program was to investigate the flux of particulate matter through the water column, emphasizing the relationship between macrozooplankton feeding and particle flux.

    2012-04-01

    Full Text Available The kinetics of oxidation of salbutamol (SBL by N-chlorobenzenesulphonamide (CAB in NaOH medium has been investigated at 303K. The reaction rate shows a first order dependence on [CAB]0 , fractional order with respect to [SBL]0 and a negative fractional order with respect to [OH-] . The addition of the reduction product, benzenesulphonamide , retards the reaction rate. The effect of dielectric constant of the medium by varying [MeOH] shows an inverse effect. The addition of chloride ions and variation of ionic strength of the medium have no significant effect on the rate of the reaction. The reaction fails to initiate polymerization of acrylamide. The oxidation products were identified. The Michaelis – Menten type of kinetics has been proposed. The reaction was studied at different temperatures and the values of thermodynamic parameters were computed. A mechanism consistent with the observed kinetics is proposed.

  20. Combining Coarse-Grained Protein Models with Replica-Exchange All-Atom Molecular Dynamics

    CERN Document Server

    Wabik, Jacek; Gront, Dominik; Kouza, Maksim; Kolinski, Andrzej

    2013-01-01

    We describe a combination of all-atom simulations with CABS, a well-established coarse-grained protein modeling tool, into a single multiscale protocol. The simulation method has been tested on the C-terminal beta hairpin of protein G, a model system of protein folding. After reconstructing atomistic details, conformations derived from the CABS simulation were subjected to replica-exchange molecular dynamics simulations with OPLS-AA and AMBER99sb force fields in explicit solvent. Such a combination accelerates system convergence several times in comparison with all-atom simulations starting from the extended chain conformation, demonstrated by the analysis of melting curves, the number of native-like conformations as a function of time and secondary structure propagation. The results strongly suggest that the proposed multiscale method could be an efficient and accurate tool for high-resolution studies of protein folding dynamics in larger systems.

    In this study we evaluated various spectral inputs for retrieval of forest chlorophyll content (Cab) and leaf area index (LAI) from high spectral and spatial resolution airborne imaging spectroscopy data collected for two forest study sites in the Czech Republic (beech forest at Štítná nad Vláří and spruce forest at Bílý Kříž). The retrieval algorithm was based on a machine learning method - support vector regression (SVR). Performance of the four spectral inputs used to train SVR was evaluated: a) all available hyperspectral bands, b) continuum removal (CR) 645 - 710 nm, c) CR 705 - 780 nm, and d) CR 680 - 800 nm. Spectral inputs and corresponding SVR models were first assessed at the level of spectral databases simulated by combined leaf-canopy radiative transfer models PROSPECT and DART. At this stage, SVR models using all spectral inputs provided good performance (RMSE for Cab sensor field of view.

    Annual fuel use for sleeper cab truck rest period idling is estimated at 667 million gallons in the United States, or 6.8% of long-haul truck fuel use. Truck idling during a rest period represents zero freight efficiency and is largely done to supply accessory power for climate conditioning of the cab. The National Renewable Energy Laboratory's CoolCab project aims to reduce heating, ventilating, and air conditioning (HVAC) loads and resulting fuel use from rest period idling by working closely with industry to design efficient long-haul truck thermal management systems while maintaining occupant comfort. Enhancing the thermal performance of cab/sleepers will enable smaller, lighter, and more cost-effective idle reduction solutions. In addition, if the fuel savings provide a one- to three-year payback period, fleet owners will be economically motivated to incorporate them. For candidate idle reduction technologies to be implemented by original equipment manufacturers and fleets, their effectiveness must be quantified. To address this need, several promising candidate technologies were evaluated through experimentation and modeling to determine their effectiveness in reducing rest period HVAC loads. Load reduction strategies were grouped into the focus areas of solar envelope, occupant environment, conductive pathways, and efficient equipment. Technologies in each of these focus areas were investigated in collaboration with industry partners. The most promising of these technologies were then combined with the goal of exceeding a 30% reduction in HVAC loads. These technologies included 'ultra-white' paint, advanced insulation, and advanced curtain design. Previous testing showed more than a 35.7% reduction in air conditioning loads. This paper describes the overall heat transfer coefficient testing of this advanced load reduction technology package that showed more than a 43% reduction in heating load.

  10. Impact of Paint Color on Rest Period Climate Control Loads in Long-Haul Trucks: Preprint

    Lustbader, J.; Kreutzer, C.; Jeffers, M.; Adelman, S.; Yeakel, S.; Brontz, P.; Olson, K.; Ohlinger, J.

    2014-02-01

    Cab climate conditioning is one of the primary reasons for operating the main engine in a long-haul truck during driver rest periods. In the United States, sleeper cab trucks use approximately 667 million gallons of fuel annually for rest period idling. The U.S. Department of Energy's National Renewable Energy Laboratory's (NREL) CoolCab Project works closely with industry to design efficient thermal management systems for long-haul trucks that minimize engine idling and fuel use while maintaining occupant comfort. Heat transfer to the vehicle interior from opaque exterior surfaces is one of the major heat pathways that contribute to air conditioning loads during long-haul truck daytime rest period idling. To quantify the impact of paint color and the opportunity for advanced paints, NREL collaborated with Volvo Group North America, PPG Industries, and Dometic Environmental Corporation. Initial screening simulations using CoolCalc, NREL's rapid HVAC load estimation tool, showed promising air-conditioning load reductions due to paint color selection. Tests conducted at NREL's Vehicle Testing and Integration Facility using long-haul truck cab sections, 'test bucks,' showed a 31.1% of maximum possible reduction in rise over ambient temperature and a 20.8% reduction in daily electric air conditioning energy use by switching from black to white paint. Additionally, changing from blue to an advanced color-matched solar reflective blue paint resulted in a 7.3% reduction in daily electric air conditioning energy use for weather conditions tested in Colorado. National-level modeling results using weather data from major U.S. cities indicated that the increase in heating loads due to lighter paint colors is much smaller than the reduction in cooling loads.

  13. Quantifying Molecular Hydrogen Emissions and an Industrial Leakage Rate for the South Coast Air Basin of California

    Science.gov (United States)

    Irish, M. C.; Schroeder, J.; Beyersdorf, A. J.; Blake, D. R.

    2015-12-01

    The poorly understood atmospheric budget and distribution of molecular hydrogen (H2) have invited further research since the discovery that emissions from a hydrogen-based economy could have negative impacts on the global climate system and stratospheric ozone. The burgeoning fuel cell electric vehicle industry in the South Coast Air Basin of California (SoCAB) presents an opportunity to observe and constrain urban anthropogenic H2 emissions. This work presents the first H2 emissions estimate for the SoCAB and calculates an upper limit for the current rate of leakage from production and distribution infrastructure within the region. A top-down method utilized whole air samples collected during the Student Airborne Research Program (SARP) onboard the NASA DC-8 research aircraft from 23-25 June 2015 to estimate H2 emissions from combustion and non-combustion sources. H2:carbon monoxide (CO) and H2:carbon dioxide ratios from airborne observations were compared with experimentally established ratios from pure combustion source ratios and scaled with the well-constrained CO emissions inventory to yield H2 emissions of 24.9 ± 3.6 Gg a-1 (1σ) from combustion engines and 8.2 ± 4.7 Gg a-1 from non-combustion sources. Total daily production of H2 in the SoCAB was compared with the top-down results to estimate an upper limit leakage rate (5%) where all emissions not accounted for by incomplete combustion in engines were assumed to be emitted from H2 infrastructure. For bottom-up validation, the NOAA Hybrid Single Particle Lagrangian Integrated Trajectory dispersion model was run iteratively with all known stationary sources in attempt to constrain emissions. While this investigation determined that H2 emissions from non-combustion sources in the SoCAB are likely significant, more in-depth analysis is required to better predict the atmospheric implications of a hydrogen economy.

  19. Molecular genetics, physiology and biology of self-incompatibility in Brassicaceae

    OpenAIRE

    Watanabe, Masao; Suwabe, Keita; Suzuki, Go

    2012-01-01

    Self-incompatibility (SI) is defined as the inability to produce zygotes after self-pollination in a fertile hermaphrodite plant, which has stamens and pistils in the same flower. This structural organization of the hermaphrodite flower increases the risk of self-pollination, leading to low genetic diversity. To avoid this problem plants have established several pollination systems, among which the most elegant system is surely SI. The SI trait can be observed in Brassica crops, including cab...

    常规的粗粒度可重构模拟电路灵活性不高,而且可重构模拟单元(CAB)结构较为复杂.针对此类问题,该文改进并设计了一种新的基于OTA的可重构模拟电路.该电路设计方案降低了CAB的复杂度,提高了CAB的使用效率.该文方法的有效性通过3个模拟设计实例(二阶低通滤波器、高通滤波器和三阶巴特沃思低通滤波器)的设计加以验证.实验结果表明,所提出的方法正确有效,可以较好地兼顾CAB资源与所要求功能的平衡.%The conventional coarse-grained reconfigurable analog circuits have bad flexibility, and the reConfigurable Analog Block (CAB) structure is complicated. In order to solve such problems, a new OTA-based reconfigurable analog circuit is presented in this paper. In this circuit scheme, the complexity of CAB is reduced and the CAB utilization rate is increased. To verify the effectiveness, three examples of analog circuit design (a second-order low pass filter, a second-order high pass filter and a low-pass third-order Butterworth filter) are presented. The experimental results indicate that the proposed circuits is effective and feasible, which make a better balance between circuit resources and functions.

    Congenital adrenal hyperplasia (CAH) is a group of recessively inherited disorders. More than 90% of all cases of CAB are caused by 21-hydroxylase deficiency. This enzyme deficiency results in reduced ability to synthesize cortisol and aldosterone and at the same time increased secretion of androgens. There is a wide spectrum of severity of the disease. The most severe forms of CAH are life-threatening, with the risk of a salt crisis in the neonatal period. CAH has special i...

    Full Text Available This work presents results from the NASA Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS study. Whole air samples were obtained on board research flights that flew over California during June 2008 and analyzed for selected volatile organic compounds, including several halogenated species. Samples collected over the South Coast Air Basin of California (SoCAB, which includes much of Los Angeles (LA County, were compared with samples from inflow air masses over the Pacific Ocean. The levels of many halocarbon species were enhanced significantly over the SoCAB, including compounds regulated by the Montreal Protocol and subsequent amendments (e.g., enhancements of 13 pptv and 11 pptv for CFC-11 and CFC-12, respectively. Emissions estimates of HFC-152a (0.98±0.05 Gg and HFC-134a (1.40±0.11 Gg in LA County for 2008 were obtained using the observed HFC:CO enhancement ratio. The emission rates were extrapolated to the SoCAB (1.48±0.07 Gg for HFC-152a and 2.12±0.17 Gg for HFC-134a and US (30.1±1.5 Gg for HFC-152a and 43.0±3.4 Gg for HFC-134a using population data. In addition, emission rates of the two HFCs in LA County and SoCAB also were calculated by a second method that utilizes air quality modeling. Estimates obtained using both methods agree well.

    Full Text Available Previous studies have suggested that oral diseases may influence the development of atherosclerosis. The aim of this study was to test the hypothesis that poor self-reported oral health (SROH and tooth loss are positively associated with coronary atherosclerotic burden (CAB. 382 consecutive subjects undergoing coronary angiography were included. Socio-demographic characteristics, cardiovascular risk factors and oral health status were collected using a standardized questionnaire, including data on SROH and use of dental prosthesis. Number of teeth and anthropometric measures were collected through clinical examinations. CAB at coronary angiography was quantified using the Friesinger score (FS. Prevalence ratios (PR were calculated with Poisson regression analyses. Mean age was 60.3 ± 10.8 years, with 63.2% males. In the bivariate analysis, there was a significant association (p 60y (PR = 1.01, 95%CI = 1.02-1.16, male gender (PR = 1.11, 95%CI = 1.03-1.19, smoking (PR = 1.08, 95%CI = 1.01- 1.16, hypertension (PR = 1.12, 95%CI = 1.03-1.22, diabetes (PR = 1.17, 95%CI = 1.05-1.21, poor SROH (PR = 1.22, 95%CI = 1.02-1.46 and tooth loss (< 20teeth present (PR = 1.10, 95%CI = 1.02-1.19. The use of dental prosthesis was not associated with CAB. The multivariate models, adjusted for age, gender, smoking, hypertension, diabetes and dyslipidemia showed that poor SROH (p = 0.03 and tooth loss (p = 0.02 were independently associated with CAB, confirming the study hypothesis.

  10. Cosmic axion background propagation in galaxies

    Francesca V. Day

    2016-02-01

    Full Text Available Many extensions of the Standard Model include axions or axion-like particles (ALPs. Here we study ALP to photon conversion in the magnetic field of the Milky Way and starburst galaxies. By modelling the effects of the coherent and random magnetic fields, the warm ionized medium and the warm neutral medium on the conversion process, we simulate maps of the conversion probability across the sky for a range of ALP energies. In particular, we consider a diffuse cosmic ALP background (CAB analogous to the CMB, whose existence is suggested by string models of inflation. ALP–photon conversion of a CAB in the magnetic fields of galaxy clusters has been proposed as an explanation of the cluster soft X-ray excess. We therefore study the phenomenology and expected photon signal of CAB propagation in the Milky Way. We find that, for the CAB parameters required to explain the cluster soft X-ray excess, the photon flux from ALP–photon conversion in the Milky Way would be unobservably small. The ALP–photon conversion probability in galaxy clusters is 3 orders of magnitude higher than that in the Milky Way. Furthermore, the morphology of the unresolved cosmic X-ray background is incompatible with a significant component from ALP–photon conversion. We also consider ALP–photon conversion in starburst galaxies, which host much higher magnetic fields. By considering the clumpy structure of the galactic plasma, we find that conversion probabilities comparable to those in clusters may be possible in starburst galaxies.

  11. Performance of cellulose acetate butyrate membranes in hyperfiltration of sodium chloride and urea feed solution

    Science.gov (United States)

    Wydeven, T.; Leban, M.

    1973-01-01

    Cellulose acetate butyrate (CAB) membranes are shown to give high salt and urea rejection with water flux of about 3 gallons/sq ft per day at 600 psig. Membranes prepared from a formulation containing glyoxal show a significant increase in flux and decrease in salt and urea rejection with drying time. Zero drying time gives maximum urea and salt rejection and is therefore most suitable for hyperfiltration of sodium chloride and urea feed solution.

  12. Trends in selected ambient volatile organic compound (VOC) concentrations and a comparison to mobile source emission trends in California's South Coast Air Basin

    Science.gov (United States)

    Pang, Yanbo; Fuentes, Mark; Rieger, Paul

    2015-12-01

    Trends in ambient concentrations of Volatile Organic Compounds (VOC) in the South Coast Air Basin (SoCAB) are compared to trends in VOC emissions from Light-Duty Gasoline Vehicles (LDGV) tested on chassis dynamometers and to trends observed in tunnel studies during the same period to understand the impacts of gasoline vehicle emissions on ambient VOC concentrations from 1999 to 2009. Annual median concentrations for most ambient VOCs decreased 40% from 1999 to 2009 in the SoCAB, based on data from the Photochemical Assessment Monitoring Stations (PAMS). Annual concentration decreases of most compounds, except 2,2,4-trimethylpentane, are highly correlated with the decrease of acetylene, a marker for tailpipe emissions from LDGV. This indicates that ambient VOC concentration decreases were likely due to tailpipe emission reductions from gasoline vehicles. Air Toxics Monitoring Network data also support this conclusion. Benzene concentration-normalized ratios for most compounds except ethane, propane, isoprene, and 2,2,4-trimethylpentane were stable even as these compound concentrations decreased significantly from 1999 to 2009. Such stability suggests that the main sources of ambient VOC were still the same from 1999 to 2009. The comparison of trends in dynamometer testing and tunnel studies also shows that tailpipe emissions remained the dominant source of tunnel LDGV emissions. The pronounced changes in 2,2,4-trimethylpentane ratios due to the introduction of Phase 3 gasoline also confirm the substantial impact of LDGV emissions on ambient VOCs. Diurnal ambient VOC data also suggest that LDGV tailpipe emissions remained the dominant source of ambient VOCs in the SoCAB in 2009. Our conclusion, which is that current inventory models underestimate VOC emissions from mobile sources, is consistent with that of several recent studies of ambient trends in the SoCAB. Our study showed that tailpipe emissions remained a bigger contributor to ambient VOCs than evaporative

    In 1973 engineers at Dryden began investigating ways to reduce aerodynamic drag on land vehicles. They began with a delivery van whose shape they changed dramatically, finally reducing its aerodynamic drag by more than 5 percent. They then turned their attention to tracator-trailers, modifying a cab-over and reducing its aerodynamic drag by nearly 25 percent. Further research identified additional areas worth attention, but in the intervening decades few of those changes have appeared.

    National ambient air quality standards (NAAQS) have been set for PM2.5 due to its association with adverse health effects. PM2.5 design values in the South Coast Air Basin (SoCAB) and San Joaquin Valley of California exceed NAAQS levels, and NH4+ and NO3- make up the largest fraction of total PM2.5 mass on polluted days. Here we evaluate fine-scale simulations of PM2.5 NH4+ and NO3- with the Community Multiscale Air Quality model using measurements from routine networks and the California Research at the Nexus of Air Quality and Climate Change 2010 campaign. The model correctly simulates broad spatial patterns of NH4+ and NO3- including the elevated concentrations in eastern SoCAB. However, areas for model improvement have been identified. NH3 emissions from livestock and dairy facilities appear to be too low, while those related to waste disposal in western SoCAB may be too high. Analyses using measurements from flights over SoCAB suggest that problems with NH3 predictions can influence NO3- predictions there. Offline ISORROPIA II calculations suggest that overpredictions of NHx in Pasadena cause excessive partitioning of total nitrate to the particle phase overnight, while underpredictions of Na+ cause too much partitioning to the gas phase during the day. Also, the model seems to underestimate mixing during the evening boundary layer transition leading to excessive nitrate formation on some nights. Overall, the analyses demonstrate fine-scale variations in model performance within and across the air basins. Improvements in inventories and spatial allocations of NH3 emissions and in parameterizations of sea spray emissions, evening mixing processes, and heterogeneous ClNO2 chemistry could improve model performance.

    Annual fuel use for sleeper cab truck rest period idling is estimated at 667 million gallons in the United States, or 6.8% of long-haul truck fuel use. Truck idling during a rest period represents zero freight efficiency and is largely done to supply accessory power for climate conditioning of the cab. The National Renewable Energy Laboratory's CoolCab project aims to reduce heating, ventilating, and air conditioning (HVAC) loads and resulting fuel use from rest period idling by working closely with industry to design efficient long-haul truck thermal management systems while maintaining occupant comfort. Enhancing the thermal performance of cab/sleepers will enable smaller, lighter, and more cost-effective idle reduction solutions. In addition, if the fuel savings provide a one- to three-year payback period, fleet owners will be economically motivated to incorporate them. For candidate idle reduction technologies to be implemented by original equipment manufacturers and fleets, their effectiveness must be quantified. To address this need, several promising candidate technologies were evaluated through experimentation and modeling to determine their effectiveness in reducing rest period HVAC loads. Load reduction strategies were grouped into the focus areas of solar envelope, occupant environment, conductive pathways, and efficient equipment. Technologies in each of these focus areas were investigated in collaboration with industry partners. The most promising of these technologies were then combined with the goal of exceeding a 30% reduction in HVAC loads. These technologies included 'ultra-white' paint, advanced insulation, and advanced curtain design. Previous testing showed more than a 35.7% reduction in air conditioning loads. This paper describes the overall heat transfer coefficient testing of this advanced load reduction technology package that showed more than a 43% reduction in heating load.

  12. Ultraviolet-B responses of nuclear genes encoding light-harvesting complex II proteins in pea (Pisum sativum) are altered by norflurazon- and photobleaching-induced chloroplast changes

    International Nuclear Information System (INIS)

    The role of functional and intact chloroplasts in mediating the ultraviolet-B (UV-B, 290–320 nm) regulation of two nuclear genes encoding light-harvesting complex II proteins in pea (Pisum sativum L. cv. Extra Early Alaska) was studied. Plants with chloroplasts lacking or containing carotenoids and functional photosystem II were obtained by growth under dim red light (0.2 µmol m−2 s−1) in the presence or absence of norflurazon (NF), an inhibitor of carotenoid biosynthesis. The NF-treatment resulted in an increase in AB80 (lhcb1*2) mRNA but no substantial change in Cab-8 (lhcb1*4) mRNA, indicating that the mRNA accumulations for AB80 and Cab-8 were differently correlated with the presence and absence of carotenoids. The mRNA levels for both Cab-8 and AB80 in the NF-treated plants were reduced to the same extent by partially photobleaching the chloroplasts with 3 h of higher intensity white light (W, 110 µmol m−2 s−1), suggesting that chloroplast integrity was equally important for transcript accumulation of both genes. The mRNAs of both Cab-8 and AB80 in non-NF-treated control plants were decreased by UV-B irradiation, with the level of AB80 mRNA reduced to a greater extent. The UV-B-induced mRNA reduction of both genes was inhibited by NF. The difference between the UV-B responses of the two genes was unaffected by NF, but was abolished by photobleaching the NF-treated plants prior to the UV-B irradiation. Therefore, the presence of carotenoids enhanced rather than prevented the UV-B down-regulation, and the difference in UV-B responses of the two genes may be dependent on chloroplast integrity.

    In this study we systematically investigated how the solvent composition used for polymer dissolution affects the porous structures of spin-coated polymers films. Cellulose acetate butyrate (CAB) and poly(methyl methacrylate) with low (PMMA-L) and high (PMMA-H) molecular weights were dissolved in mixtures of acetone (AC) and ethyl acetate (EA) at constant polymer concentration of 10 g/L The films were spin-coated at a relative air humidity of 55 {+-} 5%, their thickness and index of refraction were determined by means of ellipsometry and their morphology was analyzed by atomic force microscopy. The dimensions and frequency of nanocavities on polymer films increased with the acetone content ({phi}{sub AC}) in the solvent mixture and decreased with increasing polymer molecular weight. Consequently, as the void content increased in the films, their apparent thicknesses increased and their indices of refraction decreased, creating low-cost anti-reflection surface. The void depth was larger for PMMA-L than for CAB. This effect was attributed to different activities of EA and AC in CAB or PMMA-L solution, the larger mobility of chains and the lower polarity of PMMA-L in comparison to CAB. - Highlights: Black-Right-Pointing-Pointer Nanostructures in spin-coated polymer films depend on the solvent vapor pressure. Black-Right-Pointing-Pointer Anti-reflection polymer films are produced at high solvent vapor pressure. Black-Right-Pointing-Pointer Only shallow cavities are obtained in films of polymers with high molecular weight.

    With plans for future offshore wind farms having larger power ratings and being situated much further offshore, there will be a growing trend towards the usage of High-Voltage Direct Current (HVDC) transmission technology for submarine cables [1]. HVDC submarine cables provide lower investment cost for long-haul transmission, higher operating voltages and have no reactive power consumption, thus they have less losses than AC lines. DC transmission schemes may consist of a single polarity cab...

  15. Effects of uranium mine effluents (Caldas, Southeastern Brazil) on the aquatic biota: preliminary study on the phytoplankton community

    International Nuclear Information System (INIS)

    The present study assessed the composition of the phytoplankton community and the physicochemical variables in an area located within the ore treatment unit - Brazilian Nuclear Industries, in Caldas and also in 'Antas' dam, which is under the influence of the treatment unit. Water samples were taken from three sites; one located within the treatment unit (site CM), which receives non-treated effluents generated during the mining process; and the other sites are located in 'Antas' dam (sites Cab and 41). We determined the values of dissolved oxygen, pH, chlorophyll a, hardness, thorium, uranium, sulfate and total organic nitrogen in water samples, and identified the phytoplankton community in October 2008 and January 2009. Water samples from the site CM exhibited lower pH medium values (3.9) than from the site 41 (6.9). The highest medium value of chlorophyll a was detected in water samples at site CM (5 μg L-1), whereas the lowest value was recorded at site 41 (0.47 μg L-1). Higher medium values of sulfate were detected in water samples from site CM (1743 mg L-1) compared to site Cab (110.11 mg L-1). We identified six classes in the phytoplankton community at site CM and eight classes at sites Cab and 41. Total average density of phytoplankton were 444 ind mL-1, 316 ind mL-1 and 303 ind mL-1 at points Cab, 41 and CM, respectively. The results obtained show that the environmental conditions at site CM are not favorable to the maintenance of a high density in the phytoplankton community. (author)

    Early detection of crop injury from herbicide glyphosate is of significant importance in crop management. In this paper, we attempt to detect glyphosate-induced crop injury by PROSPECT (leaf optical PROperty SPECTra model) inversion through leaf hyperspectral reflectance measurements for non-Glyphosate-Resistant (non-GR) soybean and non-GR cotton leaves. The PROSPECT model was inverted to retrieve chlorophyll content (Ca+b), equivalent water thickness (Cw), and leaf mass per area (Cm) from leaf hyperspectral reflectance spectra. The leaf stress conditions were then evaluated by examining the temporal variations of these biochemical constituents after glyphosate treatment. The approach was validated with greenhouse-measured datasets. Results indicated that the leaf injury caused by glyphosate treatments could be detected shortly after the spraying for both soybean and cotton by PROSPECT inversion, with Ca+b of the leaves treated with high dose solution decreasing more rapidly compared with leaves left untreated, whereas the Cw and Cm showed no obvious difference between treated and untreated leaves. For both non-GR soybean and non-GR cotton, the retrieved Ca+b values of the glyphosate treated plants from leaf hyperspectral data could be distinguished from that of the untreated plants within 48 h after the treatment, which could be employed as a useful indicator for glyphosate injury detection. These findings demonstrate the feasibility of applying the PROSPECT inversion technique for the early detection of leaf injury from glyphosate and its potential for agricultural plant status monitoring.

    Coral Associated Bacteria (CAB) (N = 22) isolated from the mucus of the coral Acropora digitifera were screened for biosurfactants using classical screening methods; hemolysis test, lipase production, oil displacement, drop collapse test and emulsifying activity. Six CAB (U7, U9, U10, U13, U14, and U16) were found to produce biosurfactants and were identified by 16S ribosomal RNA gene sequencing as Providencia rettgeri, Psychrobacter sp., Bacillus flexus, Bacillus anthracis, Psychrobacter sp., and Bacillus pumilus respectively. Their cell surface hydrophobicity was determined by Microbial adhesion to hydrocarbon assay and the biosurfactants produced were extracted and characterized by Fourier Transform Infrared spectroscopy. Since the biosurfactants are known for their surface modifying capabilities, antibiofilm activity of positive isolates was evaluated against biofilm forming Pseudomonas aeruginosa ATCC10145. Stability of the active principle exhibiting antibiofilm activity was tested through various temperature treatments ranging from 60 to 100 °C and Proteinase K treatment. CAB isolates U7 and U9 exhibited stable antibiofilm activity even after exposure to higher temperatures which is promising for the development of novel antifouling agents for diverse industrial applications. Further, this is the first report on biosurfactant production by a coral symbiont. PMID:25320434

    Full Text Available Lipopolysaccharide (LPS/Endotoxin is hypothesized to play an important role in chronic inflammation associated with Type-1 diabetes (T1DM and its complications. Endotoxin core antibodies (EndoCAb, LPS binding protein (LBP and soluble CD14 (sCD14 act as modulators of LPS induced activation of innate immune system in vivo. For the present study we estimated the levels of LPS and its translocation markers in T1DM subjects with and without microvascular complications (MVC and correlate them with clinical parameters of T1DM and serum inflammatory cytokine levels (TNF-α, IL-6, IL-1β and GM-CSF.A total of 197 subjects (64 normal glucose tolerance (NGT subjects, 97 T1DM subjects without MVC and 36 with MVC were included in this study and the levels of serum LPS, its translocation markers and cytokines measured by immunoassays.Compared to NGT, T1DM subjects (both with and without MVC had significantly higher levels of LPS, reduced levels of LBP and EndoCAb along with significant increase in the levels of IL-1β, IL-6, TNF-α and GM-CSF (p<0.05. No significant change was seen in the levels of these biomarkers between T1DM subjects with and without MVC.Decreased levels of EndoCAb and LBP suggest sustained endotoxin activity in T1DM subjects even before the onset of microvascular complications.

  19. A Retrospective Management Perspective on Nearly 20 Years of the Savannah River Site Citizen Advisory Board - 13078

    International Nuclear Information System (INIS)

    The Department of Energy, Office of Environmental Management (DOE EM) program has invested in site specific advisory boards since 1994. These boards have served as a portal to the communities surrounding the DOE sites, provided a key avenue for public involvement, and have actively engaged in providing input and feedback that has informed clean up and priority decisions made by EM. Although the EM program has made considerable progress in completing its mission, work will continue for decades, including work at the Savannah River Site (SRS). It is reasonable to assume the advisory boards will continue in their role providing input and feedback to EM. The SRS Citizen Advisory Board (CAB) formed in 1994 and has issued 298 recommendations through September 2012. Although the effectiveness of the board is not measured by the number of recommendations issued, the recommendations themselves serve to illustrate the areas in which the CAB is particularly interested, and offer insight to the overall effectiveness of the CAB as a means for public participation in the EM decision making process.

    2014-01-01

    Full Text Available Tetracaine hydrochloride (TCH is one of the potent local anaesthetics. A kinetic study of oxidation of tetracaine hydrochloride by sodium N-chlorobenzenesulfonamide (chloramine-B or CAB has been carried in HClO4 medium at 303 K. The rate shows first-order dependence on [CAB]o, shows fractional–order dependence on [substrate]o, and is self-governing on acid concentration. Decrease of dielectric constant of the medium, by adding methanol, increased the rate. Variation of ionic strength and addition of benzenesulfonamide or NaCl have no significant effect on the rate. The reaction was studied at different temperatures and the activation parameters have been evaluated. The stoichiometry of the reaction was found to be 1 : 5 and the oxidation products were identified by spectral analysis. The conjugate free acid C6H5SO2NHCl of CAB is postulated as the reactive oxidizing species. The observed results have been explained by plausible mechanism and the related rate law has been deduced.

  1. Envisioning Communications with Future Stakeholders - A Case Study Using the In-Situ Decommissioning of P-Reactor

    International Nuclear Information System (INIS)

    This paper will explore opportunities to expand the CAB's public outreach by the incorporation of technologies typically used in social networks and distance learning. Envisioning opportunities to engage next generation CAB members in public involvement will be delineated by retracing the decision process used with the in-situ decommissioning of P-Reactor at the Savannah River Site (SRS). This paper will discuss existing opportunities to enable another group of stakeholders to take part in the environmental policy decision making process regarding the inclusion of some very long lived radioactive constituents. The aim of the paper will be to locate places in the current process where alternate or parallel informational dissemination pathways could exist. These alternatives will incorporate the next generation's expectation for instantaneous information and universal ownership of hand-held communication devices. The goal of this paper is to use the present framework of CAB communications and add the components of virtual networking and distance learning in hopes of bridging the generational technology gap and extending the dialog to future stakeholders.

  2. Estimating the ozone-forming potential of urban trees and shrubs

    Science.gov (United States)

    Benjamin, Michael T.; Winer, Arthur M.

    A method is presented for estimating the ozone-forming potential of biogenic hydrocarbon emissions from trees and shrubs, using the California South Coast Air Basin (SoCAB) as a case study. Hourly isoprene and monoterpenes emission rates for 308 tree and shrub species found in the SoCAB were combined with diurnal temperature and light intensity data for a representative summer day in the SoCAB to develop daily emission rates. These daily emission rates for each species were then normalized to a per tree basis using vegetation class biomass factors derived from reported leaf mass constants and tree canopy volumes. The ozone-forming potential for each of the tree and shrub species was estimated by combining the daily per tree emission rates with published maximum incremental reactivities (MIRs) for isoprene and monoterpenes. The resulting ranking of trees by ozone-forming potential can be used in tree species selection for future large-scale tree planting programs, and provides a more appropriate basis for selection than using only mass emissions of biogenic hydrocarbons.

    We investigated the effect of different membrane polymeric materials on the relationship between membrane pore size and development of membrane fouling in a membrane bioreactor (MBR). Membranes with different pore sizes were prepared using three different polymeric materials, cellulose acetate butyrate (CAB), polyvinyl butyral (PVB), and polyvinylidene fluoride (PVDF), and the development of membrane fouling in each membrane was evaluated by batch filtration tests using a mixed liquor suspension obtained from a laboratory-scale MBR. The results revealed that the optimal membrane pore size to mitigate membrane fouling differed depending on membrane polymeric material. For PVDF membranes, the degree of membrane fouling decreased as membrane pore size increased. In contrast, CAB membranes with smaller pores had less fouling propensity than those with larger ones. Such difference can be attributed to the difference in major membrane foulants in each membrane; in PVDF, they were small colloids or dissolved organics in which proteins are abundant, and in CAB, microbial flocs. The results obtained in this study strongly suggested that optimum operating conditions of MBRs differ depending on the characteristics of the used membrane.

    Travel in the back of pickup trucks has not been adequately addressed as an occupant protection issue. This study compares injuries sustained by children riding in the back of pickup trucks with those of children riding in the cab. Data were obtained from a multihospital monitoring system and the coroner in a single urban county. The series of injured children consisted of 290 children 0 through 14 years of age, 201 of whom had been riding in the cab and 89 in the back. Age distribution of the children demonstrated that it is most frequently the 10- to 14-year-olds who travel in the back. Children riding in the back were more frequently injured in noncrash events (absence of a collision), had more ejections, had more injuries, and sustained more severe injuries as measured by the Maximum Injury Score. With increased restraint use in the cab, it is likely that even greater differentials in injury severity and patterns would be realized. Education regarding the hazards of travel in the back of pickups and stronger legislation limiting the transport of children in the back of trucks are recommended. PMID:2374274

    Major depressive disorder (MDD) affects more than 10% of the population, although our understanding of the underlying aetiology of the disease and how antidepressant drugs act to remediate symptoms is limited. Major obstacles include the lack of availability of good animal models that replicate aspects of the phenotype and tests to assay depression-like behaviour in non-human species. To date, research in rodents has been dominated by two types of assays designed to test for depression-like behaviour: behavioural despair tests, such as the forced swim test, and measures of anhedonia, such as the sucrose preference test. These tests have shown relatively good predictive validity in terms of antidepressant efficacy, but have limited translational validity. Recent developments in clinical research have revealed that cognitive affective biases (CABs) are a key feature of MDD. Through the development of neuropsychological tests to provide objective measures of CAB in humans, we have the opportunity to use 'reverse translation' to develop and evaluate whether similar methods are suitable for research into MDD using animals. The first example of this approach was reported in 2004 where rodents in a putative negative affective state were shown to exhibit pessimistic choices in a judgement bias task. Subsequent work in both judgement bias tests and a novel affective bias task suggest that these types of assay may provide translational methods for studying MDD using animals. This review considers recent work in this area and the pharmacological and translational validity of these new animal models of CABs. PMID:24467454

    Films of cellulose acetate butyrate (CAB) and carboxymethylcellulose acetate butyrate (CMCAB) were deposited from ethyl acetate solutions onto bare silicon wafers (Si/SiO{sub 2}) or amino-terminated surfaces (APS) by means of equilibrium adsorption. All surfaces were characterized by means of ellipsometry, atomic force microscopy (AFM) and contact angle measurements. The presence of amino groups on the support surface favored the adsorption of CAB and CMCAB, inducing the orientation of most polar groups to the surface and the exposition of alkyl group to the air. Such molecular orientation caused increase of the dispersive component of surface energy ({gamma}{sub s}{sup d}) and decrease of the polar component of surface energy ({gamma}{sub s}{sup p}) of cellulose esters in comparison to those values determined for films deposited onto bare Si/SiO{sub 2} wafers. Adsorption behavior of jacalin or concanavalin A onto CAB and CMCAB films was also investigated. The adsorbed amounts of lectins were more pronounced on cellulose esters with high ({gamma}{sub s}{sup p}) and total surface energy ({gamma}{sub s}{sup t}) values. - Highlights: Black-Right-Pointing-Pointer Amino groups on the substrate induce the orientation of cellulose esters polar groups. Black-Right-Pointing-Pointer Amino terminated substrate caused decrease of surface energy of cellulose ester films. Black-Right-Pointing-Pointer Lectins adsorbed preferentially onto cellulose esters with high surface energy.

    1990-11-01

    The effect of maturation on the morphological and photosynthetic characteristics, as well as the expression of two genes involved in photosynthesis in the developing, current year foliage of Eastern larch (Larix laricina [Du Roi]) is described. These effects were observed on foliage during the third growing season after grafting of scions from trees of different ages onto 2 year old rootstock. Specific leaf weight (gram dry weight per square meter), leaf cross-sectional area (per square millimeter), and chlorophyll content (milligram per gram dry weight) all increase with increasing age in long shoot foliage from both indoor- and outdoor-grown trees. Net photosynthesis (NPS) (mole of CO(2) per square millimeter per second) increases with age on indoor- but not outdoor-grown trees. NPS also increases with increased chlorophyll content, but outdoor-grown scions of all ages had higher chlorophyll content, and chlorophyll does not appear to be limiting for NPS outdoors. To extend these studies of maturation-related differences in foliar morphology and physiology to the molecular genetic level, sequences were cloned from the cab and rbsS gene families of larch. Both cab and rbcS gene families are expressed in foliage but not in roots, and they are expressed in light-grown seedlings of larch but only at very low levels in dark-grown seedlings (~2% of light-grown seedlings). Steady-state cab mRNA levels are relatively higher (~40%) in newly expanding short shoot foliage from juvenile plants compared to mature plants. Unlike cab, the expression of the rbcS gene family did not seem to vary with age. These data show that the maturation-related changes in morphological and physiological phenotypes are associated with changes in gene expression. No causal relationship has been established, however. Indeed, we conclude that the faster growth of juvenile scions reported previously (MS Greenwood, CA Hopper, KW Hutchison [1989] Plant Physiol 90: 406-412) is not due to increased

Cv. Tieton and cv. Summit) were held into controlling atmosphere box (CAB), and then stored at (0 ± 0.5)t. The postharvest qualities of sweet cherry fruit were investigated at interval. Results showed that the carbon dioxide concentration in CAB were 12%-15%, and 6% higher O2 concentration. Firmness in fruit stored in CAB was higher than those in control. CAB treatment decreased the soluble solids content of sweet cherry fruit, but maintained the higher tritratable acidity and Vc content in contrast to control. CAB treatment inhibited significantly the decay incidence of sweet cherry fruit during storage and shelf-life. The lower decay incidence was found in 'Summit' fruit compared with 'Tieton' fruit. The sweet cherry fruit treated by CAB still had good sensory quality significantly after 60 days of storage and 3 days of shelf-life at ambient temperature. In general, CAB can keep better qualities, and be suitable for transportation and sales industry of sweet cherry fruit.

  11. Finding the Public Voice: A Few Observations After Experience on the SRS Citizens Advisory Board - 12226

    International Nuclear Information System (INIS)

    This Paper reflects my views on some of the difficulties and successes in seeking and reflecting the opinions and input of the typical citizen relative to the Savannah River Site (SRS) cleanup programs. These views are based on four years of membership on the SRS Citizens Advisory Board (CAB). The Savannah River Site Citizens Advisory Board was established by Department of Energy- Environmental Management in 1994 with the goal of improving cleanup decisions by reflecting priorities and concerns of stakeholders and generally improving communication with the public, particularly in the areas most impacted by site operations. The SRS CAB has been a successful venture and has had a notable record of accomplishments with approximately 285 recommendations over its 17-year history. Many of these recommendations have been very specific and have impacted Site priorities on many issues of concern to the public. However, attaining this success and truly reflecting the views of the typical citizen is a difficult proposition. This concept begs such questions as: where do you get the input? how do you get these views? and how do you know when you've gotten it right? As a Board we have had to deal with groups who seem to have a bias either in favor of or strongly opposed to certain cleanup actions or other groups who have a total focus on a single topic such as jobs. It is our role to ensure that a balanced approach is adopted which reflects the sentiments of the general public. After some four years experience on the Board I have formulated a few ideas that should make the Board one that more completely reflects public sentiments and makes useful thoughtful input. Therefore, this paper looks at the manner and difficulty of seeking input and generally communicating with the public while offering some views on how to improve the process. The Citizens Advisory Board was envisioned as a body of private citizens who looked at cleanup activities of the Site and reflected the public

    Molecular analyses of sedimentary organic matter are powerful tools in assessing the origin of organic matter and its thermal maturity as well as constraining ancient environmental conditions, such as as marine productivity, anoxia in bottom waters or the photic zone and sea surface temperatures. This communication presents the study of four sections recording the OAE1a (early Aptian) in Spain, which are located in two broad basins respectively located in the South and the North of Iberia: the Southern Iberian Palaeomargin (Carbonero - CAB, La Frontera - XF and Cau - CAU sections) and the Cantabrian Basin (Puente Nansa - PN section). These sections represent depositional settings ranging from platform (CAU, PN) to pelagic environments (CAB, XF). C-isotope profiles and biostratigraphic data are used to define the interval corresponding to the OAE 1a. Here we focus on the biomarker composition of the organic-rich facies, and the integration of these data with the sedimentology, stratigraphy and paleogeography. The study has been based mainly upon the analysis of samples with Gas Chromatography-Mass Spectrometry (GCMS). Four main groups of compounds are present in all sections: n-alkanes, isoprenoids, hopanes and steranes. n-Alkanes and isoprenoids (pristane and phytane) are dominant in most samples. To facilitate interpretation of these distributions, we have calculated the TAR (terrestrial aquatic ratio derived from the ratio of long to short chain compounds) and also the OEP (odd over even predominance of n-alkanes). The ratio of pristane to phytane and various isoprenoid/n-alkanes ratios have also been calculated. The hopanes are represented by a range of C27 to C35 components, with the specific isomers varying amongst the sections due to differences in thermal maturity. Steranes occur as a range of C27, C28 and C29 isomers, whereas diasteranes only occur in the most thermally mature section (CAB). Other compounds of interest include gammacerane and dinosterane

  14. Identification of antiviralrelevant genes in the cultured fish cells induced by UV-inactivated virus

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    UV-inactivated grass carp hemorrhage virus (GCHV) can induce high titer of interferon in cultured CAB (crucian carp (Carassius auratus L.) blastulae) cells, and thus defend host cells against the virus invasion. The mechanism is proposed that an antiviral state should be established in the host cells by activating expression of a set of antivi-ral-relevant genes. In this study, suppressive subtractive hy-bridization is applied to constructing a subtracted cDNA library with mRNAs isolated from UV-inactivated GCHV infected and mock-infected CAB cells. 272 differential cDNA fragments are identified by both PCR and dot blot from the subtractive cDNA library. Sequencing analysis reveals 69 genes, including 46 known gene homologues, and 23 unknown putative genes. The known genes include the genes involved in interferon signaling pathways, such as Stat1 and Jak1, the antiviral genes, such as Mx and Viperin, and a set of interferon-stimulated genes observed in mammalian cells. Most of the unknown putative genes contain AU-rich ele-ment in their sequences. Differential expressions of these genes are further confirmed by virtual Northern blot and RT-PCR. The data imply that UV-inactivated GCHV is not only able to induce production of interferon in the infected CAB cells, but also leads to the expression of a series of antiviral-relevant genes or immune-relevant genes, and therefore reveals that the signaling pathway of interferon system and antiviral mechanism in fish are similar to those in mammals.

  15. Isolation and chimerization of a highly neutralizing antibody conferring passive protection against lethal Bacillus anthracis infection.

    Ronit Rosenfeld

    Full Text Available Several studies have demonstrated that the passive transfer of protective antigen (PA-neutralizing antibodies can protect animals against Bacillus anthracis infection. The standard protocol for the isolation of PA-neutralizing monoclonal antibodies is based upon a primary selection of the highest PA-binders by ELISA, and usually yields only few candidates antibodies. We demonstrated that by applying a PA-neutralization functionality-based screen as the primary criterion for positive clones, it was possible to isolate more than 100 PA-neutralizing antibodies, some of which exhibited no measurable anti-PA titers in ELISA. Among the large panel of neutralizing antibodies identified, mAb 29 demonstrated the most potent activity, and was therefore chimerized. The variable region genes of the mAb 29 were fused to human constant region genes, to form the chimeric 29 antibody (cAb 29. Guinea pigs were fully protected against infection by 40LD(50B. anthracis spores following two separate administrations with 10 mg/kg of cAb 29: the first administration was given before the challenge, and a second dose was administered on day 4 following exposure. Moreover, animals that survived the challenge and developed endogenous PA-neutralizing antibodies with neutralizing titers above 100 were fully protected against repeat challenges with 40LD(50 of B. anthracis spores. The data presented here emphasize the importance of toxin neutralization-based screens for the efficient isolation of protective antibodies that were probably overlooked in the standard screening protocol. The protective activity of the chimeric cAb 29 demonstrated in this study suggest that it may serve as an effective immunotherapeutic agent against anthrax.

  17. Butyl acetate synthesis using immobilized lipase in calcium alginate beads

    International Nuclear Information System (INIS)

    The esterification reaction of acetic acid and n-butanol using immobilized lipase encapsulated in calcium alginate beads (Lipase - CAB) and in chitosan coated calcium alginate beads (Lipase-CCAB) in n-hexane under mild reaction conditions were studied. Effects of temperature and substrate concentration (acetic acid and n-butanol) using Lipase - CAB, Lipase - CCAB and free lipase on the esterification reaction and their thermal stability towards esterification reaction were investigated. Results of temperature studies showed that the butyl acetate conversion increased with increase of temperature and reached the highest yield of about 70% around 50 degree Celsius for both immobilized systems but the yield of product catalyzed by free enzyme decreased as temperature was increased. Thermal stabilities studies showed that the Lipase-CCAB and Lipase-CAB were stable throughout the temperature range of 30-60 degree Celsius. However, free lipase became less stable at temperatures higher than 50 degree Celsius. The substrates, n-butanol and acetic acid exerted different effects on the esterification reaction and the reaction was favoured by higher acetic acid concentration than butanol. Kinetics parameters, Km and Vmax values for both substrates and the specific activities of the three enzyme system were also determined. The beads morphology was examined using SEM. Batch-wise operational stability studies for both immobilized systems demonstrated that the immobilized lipase performed better in the batch wise reactor system than the continuous bioreactor system and that the immobilized lipase remained active for at least 5 cycles of batch wise esterification reactions.

    This study investigated the structural relaxation of micronized fluticasone propionate (FP) under different lagering conditions and its influence on aerodynamic particle size distribution (APSD) of binary and tertiary carrier-based dry powder inhaler (DPI) formulations. Micronized FP was lagered under low humidity (LH 25 C, 33% RH [relative humidity]), high humidity (HH 25°C, 75% RH) for 30, 60, and 90 days, respectively, and high temperature (HT 60°C, 44% RH) for 14 days. Physicochemical, surface interfacial properties via cohesive-adhesive balance (CAB) measurements and amorphous disorder levels of the FP samples were characterized. Particle size, surface area, and rugosity suggested minimal morphological changes of the lagered FP samples, with the exception of the 90-day HH (HH90) sample. HH90 FP samples appeared to undergo surface reconstruction with a reduction in surface rugosity. LH and HH lagering reduced the levels of amorphous content over 90-day exposure, which influenced the CAB measurements with lactose monohydrate and salmeterol xinafoate (SX). CAB analysis suggested that LH and HH lagering led to different interfacial interactions with lactose monohydrate but an increasing adhesive affinity with SX. HT lagering led to no detectable levels of the amorphous disorder, resulting in an increase in the adhesive interaction with lactose monohydrate. APSD analysis suggested that the fine particle mass of FP and SX was affected by the lagering of the FP. In conclusion, environmental conditions during the lagering of FP may have a profound effect on physicochemical and interfacial properties as well as product performance of binary and tertiary carrier-based DPI formulations.

    The chemolithotrophic ammonia-oxidizing bacteriumNitrosomonas europaea is known to be highly resistant to starvationconditions. The transcriptional response of N. europaea to ammoniaaddition following short- and long-term starvation was examined by primerextension and S1 nuclease protection analyses of genes encoding enzymesfor ammonia oxidation (amoCAB operons) and CO2 fixation (cbbLS), a third,lone copy of amoC (amoC3), and two representative housekeeping genes(glyA and rpsJ). Primer extension analysis of RNA isolated from growing,starved, and recovering cells revealed two differentially regulatedpromoters upstream of the two amoCAB operons. The distal sigma 70 typeamoCAB promoter was constitutively active in the presence of ammonia, butthe proximal promoter was only active when cells were recovering fromammonia starvation. The lone, divergent copy of amoC (amoC3) wasexpressed only during recovery. Both the proximal amoC1,2 promoter andthe amoC3 promoter are similar to gram-negative sigma E promoters, thusimplicating sigma E in the regulation of the recovery response. Althoughmodeling of subunit interactions suggested that a nonconservative prolinesubstitution in AmoC3 may modify the activity of the holoenzyme,characterization of a Delta amoC3 strain showed no significant differencein starvation recovery under conditions evaluated. In contrast to the amotranscripts, a delayed appearance of transcripts for a gene required forCO2 fixation (cbbL) suggested that its transcription is retarded untilsufficient energy is available. Overall, these data revealed a programmedexit from starvation likely involving regulation by sigma E and thecoordinated regulation of catabolic and anabolic genes.

    Sclerotinia sclerotiorum is an emerging fungal pathogen affecting soybeans in the United States. In response to its emergence, exposures to particulates, bioaerosols, endotoxins, S. sclerotiorum, and beta(1-3)-glucans were characterized during soybean harvesting. Air sampling was performed on soybean harvesters (combines) and on the farmers in closed cabs as personal samples during harvesting at 17 farms in 1997 and repeated at 15 in 1998. S. sclerotiorum infestation was evident in the fields at 8 of the sites (44%). The geometric mean concentrations (and geometric standard deviations) measured on the combines in 1998 were as follows: total dust, 11.9 (2.8) mg/m(3); inhalable dust 11.7 (6.4) mg/m(3); and beta(1-3)-glucans, 5027 (7) ng/m(3). Values for the personal samples in 1998 were as follows: total dust, 1.2 (6.7) mg/m(3); inhalable dust, 1.1 (5.3); and beta(1-3)-glucans, 674 (9) ng/m(3). These concentrations were two- to threefold higher than in the previous year. Ambient endotoxin concentrations were 4438 EU/m(3) in Year I and 459 EU/m(3) in Year II. Particle size distribution measurements on the combines yielded mass median aerodynamic diameters of 6.6 microm on the combine and 4.0 microm inside the combine cab. Closed combine cabs provided an average workplace protection factor of 11.7 for total dust. Nevertheless, personal exposures to organisms inside combine cabins ranged from 3.6 x 10(4) to 4.0 x 10(8) organisms/m(3). These data indicate the potential exists for high exposures to organic dust and bioaerosols during soybean harvesting. PMID:12908864

    In a greenhouse study designed to quantify and compare stress responses of four genotypes of Brassica rapa, broccolette (bro), cabbage (cab), turnip (tur), and oil, leaf water potential and net CO2 assimilations were measured. Individuals from each genotype, grown either with high or low nitrogen, were exposed to experimental drought of the same duration. One hypothesis was that the genotypes would differ significantly in their responses to periodic drought. The other hypothesis was that the nitrogen treatment versus no nitrogen treatment would play a significant role in the stress responses during drought. It would be expected that the nitrogen treated would have greater dry leaf mass. A LI-6400 XT portable photosynthesis system was used to obtain A/Ci curves (net CO2 assimilation rate versus substomatal CO2) for each treatment group. Predawn and midday water potentials were obtained throughout the hydrated and drought periods using a Model 670 pressure chamber. The dry leaf mass was significantly greater among the high nitrogen group versus the low nitrogen group for each genotype. Nitrogen and genotype were both determinants in variation of water potentials and net CO2 assimilation. Bro and cab genotypes with high nitrogen showed the highest net CO2 assimilation rates during hydration, but the assimilation rates dropped to the lowest during droughts. The water potentials for bro and cab were lower than values for tur and oil. Nitrogen treated genotypes had lower water potentials, but higher net CO2 assimilation rates. Bayesian ecophysiological modeling with the TREES model showed significant differences in trait expression, quantified in terms of differences in model parameter posteriors, among the four genotypes.

    This study mainly uses the move and step analysis to conduct a contrastive genre analysis on the selected 20 Chinese ad⁃mission brochures (CABs) and 20 American admission brochures (AABs). Differences in moves, move sequences and step arrange⁃ments have revealed themselves in this comparison. Firstly, Chinese university admission brochures cast more focus on basic infor⁃mation about the university, the application procedure and admission criteria, while American universities, besides offering such in⁃formation, also emphasize the promotional function of the admission brochures. They use appealing and creative moves to commer⁃cially‘sell’advantages of the university to the potential applicants. Secondly, based on Kress&van Leeuwen’s visual grammar symbolic meaning, images and colors in admission brochures are also explored and analyzed as language. For one thing, after count⁃ing the frequency of the four categories of images, namely portrait, campus scenery, campus life pictures and graphs, it is found that, compared with CABs, AABs have a highly more obvious tendency in using images. The images are used as an effective tool to increase the sense of credibility, identity-recognition, attract reader’s attention, and help understanding, making the facts and in⁃formation more intuitive. For another thing, the main colors used in the brochures are yet another noticeable feature. Especially in American brochures, universities tend to use their‘traditional colors’in the brochure to achieve a sense of consistency. Some Chi⁃nese brochures also follow this promotional strategy, yet a large percentage of them do not use any recognizable colors other than the printed black and white. Based on these differences, suggestions are put forward from perspectives including choice of moves and steps to improve the quality of CABs, hopefully raising their acceptance in the international level.

    Background Carvedilol, an antagonist of α1- and β-adrenergic receptors, has shown efficacy in reducing all-cause death and arrhythmia death for ischemic heart disease and congestive heart failure in several large-scale trials. It has been found to prevent ventricular remodeling, and recently was reported to reverse down-regulation of Na+ channel in a chronic heart failure model. This study was conducted to investigate whether carvedilol could reverse the ion remodeling in a myocardial infarction model of rabbit.Methods After the procedure of coronary ligation, animals were randomized to placebo or carvedilol treatment (5 mg/kg). Action potentials, L-type calcium current (Ica L) and the effect of isoproterenol stimulation on Ica L were measured using whole-cell patch method. Evaluation of the expression of calcium channel subunits was carried out by RT-PCR and Western blot. Results The results indicate that mean peak Ica L densities (pA/pF) at +10 mV was reduced in postinfarction myocytes (5.33±0.45, n=25) compared to sham myocytes (6.52±0.21, n=20). Treatment of myocardial infarction rabbits with carvedilol could restore it partially (5.91±0.39, n=20, P<0.05). However, steady-state activation parameters were similar in three groups. With stimulation by isoproterenol (1 μmol/L) Ica L increased in all three groups, but the increase was smaller in postinfarction myocytes. mRNA levels of calcium channel subunit CaA1 gene was decreased but CaB2a, CaB2b and CaB3 mRNA levels did not change after MI. Corresponding change in CaA1 protein was also observed. Conclusions The results demonstrate that carvedilol restores Ica L density and reverse the downregulation of CaA1 postinfarction.

    We present a review of the biological systematic research in Latin America during the twentieth century, applying a bibliometric analysis to the information contained in international databases with the largest number of biological records: Biosis (since 1969), CAB (since 1910) and Science Citation Index (since 1900), to recognize certain patterns and trends regarding the document production. We obtained 19079 documents and 1387 journals for Biosis, 14326 and 2537 for CAB, 3257 and 1636 for SCI. Of the documents, 54.6% related to new species, 15.3% dealt with morphology, 14.9% keys, 12.5% descriptions, 10.6% cases of synonymies, 6% new genera, 4.9% new geographical records, 23.6% geographical distribution, 4.2% redescriptions, and 3.6% with new nomenclatural combinations. The regions mentioned were South America with 11.9%, Central America with 4% and America (all) with 2.56%. Nineteen Latin American countries appear, whereas outside this region we found the United States of America with 12.6% of representation and Canada with 3%. Animals (65.6%) were the most studied taxa, which was 1.7 times higher than what was published for plants (37%), 11 times higher than fungi (6%) and nearly 30 times higher than microorganisms (2.3%). Out of the 155 journals that produced 66% of the papers, 76.5% were better represented in Biosis, 21.4% in CAB and 2% in SCI. Twenty-nine journals published 33% of the articles, the maximum number of records obtained was 69% for Biosis, CAB 24% and 6.9% for SCI, three (10.3%) are in biology, 11 (37.9%) in botany, 13 (44.8%) zoology, and two (6.9%) paleontology; eight of these journals (27.5%) were published in Latin America and twenty were indexed in the Science Citation Index. In the last two years more journals of the region that publish on taxonomy have been indexed, but their impact factor is still low. However, the impact factor of a number of Latin American journals that published biodiversity increased with time. Countries that are

    Concentric anchor beacons (CAB) localization algorithm is a range -free wireless sensor networks localization algorithm. Comparing with the traditional range localization algorithm, although it can reduce the nodes energy consumption, the localization accuracy is no better than traditional range localization approaches. In order to further improve the accuracy of localizing nodes, an improved weighted centroid algorithm based on CAB is proposed after analyzing the radio propagation path loss. First, the process of this improved algorithm is introduced. Then, the influence of communication radius on the accuracy of this new localization algorithm was simulated. After that, the accuracy of this localization algorithm were compared with the existing several kinds of range - free localization methods. Simulation results show that this new algorithm has a higher positioning accuracy and not sensitive to communication radius, and it has some value in productive practice.%研究无线传感器定位准确性问题,针对测量位置节点信息,为了提高无线传感器网络的定位精度,采用同心圆定位算法(CAB)是一种免测距的无线传感器定位算法,相比于传统的测距方法能降低节点的能量消耗,但是定位精度却不及传统的测距定位方法.提出在同心圆定位算法(CAB)的基础上,通过分析无线电传播路径损耗采用了一种加权同心圆定位算法.给出了算法的流程,仿真分析了通信半径对新算法定位精度的影响,比较了算法定位精度与现有的几种免测距定位方法的定位精度.仿真结果表明,改进算法有较高的定位精度而且对距离不敏感,对实际工程提供应用价值.

  13. Top-down estimate of surface flux in the Los Angeles Basin using a mesoscale inverse modeling technique: assessing anthropogenic emissions of CO, NOx and CO2 and their impacts

    2013-04-01

    Full Text Available We present top-down estimates of anthropogenic CO, NOx and CO2 surface fluxes at mesoscale using a Lagrangian model in combination with three different WRF model configurations, driven by data from aircraft flights during the CALNEX campaign in southern California in May–June 2010. The US EPA National Emission Inventory 2005 (NEI 2005 was the prior in the CO and NOx inversion calculations. The flux ratio inversion method, based on linear relationships between chemical species, was used to calculate the CO2 inventory without prior knowledge of CO2 surface fluxes. The inversion was applied to each flight to estimate the variability of single-flight-based flux estimates. In Los Angeles (LA County, the uncertainties on CO and NOx fluxes were 10% and 15%, respectively. Compared with NEI 2005, the CO posterior emissions were lower by 43% in LA County and by 37% in the South Coast Air Basin (SoCAB. NOx posterior emissions were lower by 32% in LA County and by 27% in the SoCAB. NOx posterior emissions were 40% lower on weekends relative to weekdays. The CO2 posterior estimates were 183 Tg yr−1 in SoCAB. A flight during ITCT (Intercontinental Transport and Chemical Transformation in 2002 was used to estimate emissions in the LA Basin in 2002. From 2002 to 2010, the CO and NOx posterior emissions decreased by 41% and 37%, respectively, in agreement with previous studies. Over the same time period, CO2 emissions increased by 10% in LA County but decreased by 4% in the SoCAB, a statistically insignificant change. Overall, the posterior estimates were in good agreement with the California Air Resources Board (CARB inventory, with differences of 15% or less. However, the posterior spatial distribution in the basin was significantly different from CARB for NOx emissions. WRF-Chem mesoscale chemical-transport model simulations allowed an evaluation of differences in chemistry using different inventory assumptions, including NEI 2005, a gridded CARB

    A transcriptional attenuation mechanism regulates expression of the bacterial tnaCAB operon. This mechanism requires ribosomal arrest induced by the regulatory nascent TnaC peptide in response to free L-tryptophan (L-Trp). In this study we demonstrate, using genetic and biochemical analyses, that in Escherichia coli, TnaC residue I19 and 23S rRNA nucleotide A2058 are essential for the ribosome’s ability to sense free L-Trp. We show that the mutational change A2058U in 23S rRNA reduces the con...

    2007-04-01

    Simple and reproducible spectrophotometric methods have been developed for determination of dopaminergic drugs used for Parkinson's disease, cabergoline (CAB) and ropinirole hydrochloride (ROP), in pharmaceutical preparations. The methods are based on the reactions between the studied drug substances and ion-pair agents [methyl orange (MO), bromocresol green (BCG) and bromophenol blue (BPB)] producing yellow colored ion-pair complexes in acidic buffers, after extracting in dichloromethane, which are spectrophotometrically determined at the appropriate wavelength of ion-pair complexes. Beer's law was obeyed within the concentration range from 1.0 to 35 microg ml(-1). The developed methods were applied successfully for the determination of these drugs in tablets.

  5. Refractive index modulation in polymer film doped with diazo Meldrum's acid

    2016-08-01

    Diazo Meldrum's acid undergoes a photoreaction induced by UV light and it is used as photosensitizer in photoresists. Upon photoreaction, a change in refractive index occurs, which makes this system interesting for volume holography. We report on the sublimation effect at room temperature and the effect of photoirradiation on the refractive index in thin films of CAB (Cellulose acetate butyrate) doped with different amount of diazo Meldrum's acid. A net modulation of the refractive index of 0.01 is achieved with 40% of doping ratio together with a reduction of the film thickness.

  9. Top-down estimate of surface flux in the Los Angeles Basin using a mesoscale inverse modeling technique: assessing anthropogenic emissions of CO, NOx and CO2 and their impacts

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available We present top-down estimates of anthropogenic CO, NOx and CO2 surface fluxes at mesoscale using a Lagrangian model in combination with three different WRF model configurations, driven by data from aircraft flights during the CALNEX campaign in southern California in May–June 2010. The US EPA National Emission Inventory 2005 (NEI 2005 was the prior in the CO and NOx inversion calculations. The flux ratio inversion method, based on linear relationships between chemical species, was used to calculate the CO2 inventory without prior knowledge of CO2 surface fluxes. The inversion was applied to each flight to estimate the variability of single-flight-based flux estimates. In Los Angeles (LA County, the uncertainties on CO and NOx fluxes were 10% and 15%, respectively. Compared with NEI 2005, the CO posterior emissions were lower by 43% ± 6% in LA County and by 37% ± 10% in the South Coast Air Basin (SoCAB. NOx posterior emissions were lower by 32% ± 10% in LA County and by 27% ± 15% in the SoCAB. NOx posterior emissions were 40% lower on weekends relative to weekdays. The CO2 posterior estimates were 183 ± 18 Tg yr−1 in SoCAB. A flight during ITCT in 2002 was used to estimate emissions in the LA Basin in 2002. From 2002 to 2010, the CO and NOx posterior emissions decreased by 41% and 37%, respectively, in agreement with previous studies. Over the same time period, CO2 emissions increased by 10% ± 14% in LA County but decreased by 4% ± 10% in the SoCAB, a statistically insignificant change. Overall, the posterior estimates were in good agreement with the California Air Resources Board (CARB inventory, with differences of 15% or less. However, the posterior spatial distribution in the basin was significantly different from CARB for NOx emissions. WRF-Chem mesoscale chemical-transport model simulations allowed an evaluation of differences in chemistry using different inventory assumptions, including NEI 2005, CARB 2010 and the posterior

    By microsequencing and cDNA cloning we have identified the transformation-sensitive protein No. IEF SSP 9302 as the human homologue of calumenin. The nucleotide sequence predicts a 315 amino acid protein with high identity to murine and rat calumenin. The deduced protein contains a 19 amino acid N...... and pancreas and at very low levels in brain and liver. Calumenin belongs to a family of multiple EF-hand proteins that include the ER localized proteins reticulocalbin and ERC-55 and the Golgi localized Cab45. Since its Ca2+ binding may be important for the function of the protein we have used microdialysis...
