Resistencia a antibióticos y presencia de plásmidos en Aeromonas hydrophila, Vibrio fluvialis y Vibrio furnissii, aislados de Carassius auratus auratus Anatibiotic resistance and presence of plasmids in Aeromonas hydrophila, Vibrio fluvialis , and Vibrio furnissii isolated from Carassius auratus aur

We isolated and identified 70 bacterial strains from the ornate fish species Carassius auratus, in specimens with signs of infection. The isolated and identified bacterial species, Aeromonas hydrophila, Vibrio fluvialis , and Vibrio furnissii, have been reported to cause diarrhea in humans, and the first two are considered very aggressive pathogens in Cyprinus carpio cultures. For this reason, antibiotics to avoid and control the presence of these bacteria have been inadequately used and abused. The uncontrolled use of antibiotics has given rise to the presence of an R-plasmid in bacteria, as a response to the environmental stress represented by these chemical compounds. When R-plasmid carrying bacteria are transmitted directly to humans, be it by direct contact with the host during handling in culture, as a pet, in consumption, or by a conjunction of all these factors, the problem exceeds aquaculture and becomes a public health issue. All the studied strains presented antibiotic resistance. We recorded resistance to more than one antibiotic, and up to seven in some cases. Furthermore, 100% of the strains carried plasmids resistant to antibiotics with molecular weights ranging from 25.7kb to 6.6 kb. The Aeromonas hydrophila strains presented resistance to the following antibiotics: cephalothin (CF), tetracycline (T), nitrofurantoin (NF), ampicillin (AMP), carbenicillin (CB), and kanamicyn (K). The molecular weights of the plasmids found ranged from 25.7 to 6.6 kb, 24% of Aeromonas hydrophila carried plasmids of 14.2 kb and 21% of 22.5 kb. Plasmids of 15 to 6.9 kb were extracted from Vibrio fluvialis strains, 58% were of 15 kb and were resistant to CF, AMP, T, NF, CB. Vibrio furnissii carrried plasmids ranging from 15 to 6.6 kb, 46% these strains were of 14.2 kb and presented resistance to CF, AMP, T, NF, CB, and K. The results were the same independent of the origin of the samples, be it water, food or an organism. None of the plasmids were able to transfer to Escherichia coli and no incompatibility group could be determined.
Isolation and identification of lactobacillus species from the vagina and their antimicrobial properties

The microbial resident in the vagina is a heterogeneous flora containing bacteria. This microbial flora plays an important role in regular vagina function and support host defense from attack by pathogens. In this study Lactobacilli spp. isolated from healthy women and their antimicrobial activity was evaluated. One hundred and three healthy women referred to women clinics in Ahvaz-Iran were subjected for this study. A vaginal swab of each one inoculated in MRS broth media. After 24 h incubation the specimens were subcultured on MRS agar media. The Gram positive bacilli where isolated for more identification by using polymerase chain reaction (PCR) with genus and species-specific primers. The antimicrobial activity of confirmed lactobacilli where tested against Candida albicans andStaphylococcus aureus. Fifty-one samples out of 103 were positive for Lactobacillus genus primers. Twenty-four isolates were Lactobacillus acidophilus and two species were identified as Lactobacillus plantarum and 2 as Lactobacillus casei. Twenty-three other isolates were just positive by genus primer. Twenty strains of L. acidophilus and one strain of L. plantarum, showed antimicrobial activity against S. aureus and C. albicans. The objectives of this study showed that less than 50% of healthy ladies in Ahvaz city- Iran can be supported from vaginal pathogens by lactobacilli probiotics but others are in risk of attack by harmful microbes. Key word: Lactobacillus, vagina pathogens, antimicrobial.
Studying the genetic relationship among three populations for Musca domestica L. (Diptera : Muscidae) in Iraq by using RAPD- PCR Technique

Randomly Amplified Polymorphic DNA Polymerase Chain Reaction RAPD-PCR Technique was used in this study to investigate genetic relationship among three populations of housefly Musca domestica (L.) from Northern, Middle and Southern Iraq. Environmental conditions such as temperature, relative humidity and the amount of annual rainfall to be different in the northern, Middle and Southern Iraq , In addition to the northern of Iraq away from the southern a distance of 1,000 km and away from the middle distance of approximately 500 km or less, as well as there are some mountains and rivers separating northern Iraq from the middle and south , these environmental conditions act as geographical barriers to gen flow among the three population. We have used in this study nine primers and Tools For Population Genetic Analysis (TFPGA) software was used to calculate percentage efficiency of each primer and percentage of discriminatory ability of each primer , In addition to Nei’s genetic identity. The results showed that the primer No. 3 gave the highest of percentage efficiency and percentage of discriminatory ability which is 17.24 and 17.07 respectively . , While primer No. 6 gave The lowest of percentage efficiency and percentage of discriminatory ability which is 5.74 and 6.09 respectively . , The genetic identity among three populations ranges from 1.383 to 1.586, which reveals that there is a low level of genetic identity reflecting the fact that the environmental conditions appear to act as a barrier to gene flow among these populations.

Design and Implementation of Low Power High Speed 32-Bit HCSA

In the design of carry select adder, the requirement of area, speed and power consumption is of prime importance. Power dissipation is one of the most important design objectives in integrated circuits, after speed. Carry select adder (CSLA) is one of the fast adder used to perform fast arithmetic operations as we select the carry beforehand and calculate the sum output for both the carry conditions i.e. for Cin=1 or Cin=0. The most fundamental arithmetic operations in any ALU is addition. It has been ranked the most extensively used operation among a set of real-time digital signal processing benchmarks from application-specific DSP to general purpose processors [1]. Efficient utilization of CSLA depends upon the gate level modification. In this paper, 32-bit linear CSLA has been modified in such a way that the pipeline architecture that we have developed consumes minimum power as well as provide a high speed. In this project, the entire adder architecture has been implemented using VHDL and simulated using Mentor Graphics tool suite. The architecture is then further evaluated in FPGA using Xilinx ISE Design Suite.
Angular dependent Mie theory for nanowire photovoltaics

Semiconductor nanowires have been intensively investigated for photovoltaic applications because of their unique optical properties. Nanowire-based solar cells are believed to offer high operating efficiency at lower fabrication cost due to resonant interaction with light and therefore, efficient light absorption. Light interaction with nanowires is commonly described by Mie theory. In the last few years, experimental studies on light scattering and absorption in nanowires, as a function of the nanowire diameter and wavelength of incident light, have been successfully described with Mie theory. However, light absorption in nanowires as a function of the angle of incidence has only been studied theoretically. For this thesis, the angle-dependent light absorption in individual indium phosphide nanowires has been studied experimentally using a time-reversed Fourier microscope. Our results show that Mie theory fails to describe the angle-dependent light absorption in vertically-oriented nanowires. Since many nanowire-based solar cell designs utilize this nanowire orientation, this is an important result. We conclude that for maximizing the absorption in nanowire-based solar cells, other light absorption mechanisms need to be taken into account besides of those considered in Mie theory.
A context-tree weighting method for text generating sources

Summary form only given. The authors discuss context tree weighting (Willems et al. 1995). This was originally introduced as a sequential universal source coding method for the class of binary tree sources. The paper discusses the application of the method to the compaction of ASCII sequences. The estimation of redundancy and model redundancy are also considered.
Use of centrifuge modelling to improve lessons learned from earthquake case histories.

Current procedures relate potential liquefaction induced settlements to foundation size and liquefiable depth. However, the analysis of field case histories suggests that the influence of foundation bearing pressure may also be a significant factor influencing such phenomena. Data from 24 buildings that suffered settlement and tilting as a consequences of soil liquefaction during the February 27th 2010 Maule earthquake in Chile, are herein analyzed and compared with data from other earthquakes. Although case history data play a crucial role in geotechnical earthquake engineering, in many cases their analysis is limited to speculation therefore experimental verification is often required. Thanks to the significant development in dynamic geotechnical centrifuge modelling in the last 30 years, we are today able to carefully reproduce field motions enhancing the reliability of experimental results. This is the case for the centrifuge tests discussed in this paper, which have been the first tests performed on the University of Dundees new Actidyn Q67-2 servo-hydraulic earthquake shaker.
The Effect of Common Ground on How Speakers Use Gesture and Speech to Represent Size Information

Past research has investigated the impact of mutual knowledge on communication by focusing mainly on verbal communication. This study uses a wider focus, which includes speech and gesture. Speakers completed a referential communication task with recipients who did or did not share with them knowledge about the size of certain entities. The results showed that when such common ground exists between interlocutors, speakers' use of gesture and speech is affected. The main finding was that when speakers talked to recipients for whom the size information was new information, they represented this information predominantly in gesture only or in gesture and speech. However, when speakers talked to recipients with whom they shared knowledge about the entities' size, speakers encoded this information mainly verbally but not gesturally. The results are interpreted with respect to past research into common ground and language use, the pragmatics of gesture, and theories of gesture production.
IS IMPLEMENTATION OF WHO SURGICAL SAFETY CHECKLIST (2009) WILL REDUCE THE RATE OF MAJOR POST OPERATIVE COMPLICATIONS AT ZAGAZIG UNIVERSITY HOSPITAL? (AN INTERVENTION STUDY)

It is recommended to use the Surgical Safety Checklist in all operative procedures.
Sulfur deposition changes under sulfate geoengineering conditions: quasi-biennial oscillation effects on the transport and lifetime of stratospheric aerosols

Sustained injection of sulfur dioxide (SO 2 ) in the tropical lower stratosphere has been proposed as a climate engineering technique for the coming decades. Among several possible environmental side effects, the increase in sulfur deposition deserves additional investigation. In this study we present results from a composition–climate coupled model (University of L'Aquila Composition-Chemistry Model, ULAQ-CCM) and a chemistry-transport model (Goddard Earth Observing System Chemistry-Transport Model, GEOS-Chem), assuming a sustained lower-stratospheric equatorial injection of 8 Tg SO 2 yr −1 . Total S deposition is found to globally increase by 5.2 % when sulfate geoengineering is deployed, with a clear interhemispheric asymmetry (+3.8 and +10.3 % in the Northern Hemisphere (NH) and the Southern Hemisphere (SH), due to +2.2 and +1.8 Tg S yr −1 , respectively). The two models show good consistency, both globally and on a regional scale under background and geoengineering conditions, except for S-deposition changes over Africa and the Arctic. The consistency exists with regard to time-averaged values but also with regard to monthly and interannual deposition changes. The latter is driven essentially by the variability in stratospheric large-scale transport associated with the quasi-biennial oscillation (QBO). Using an externally nudged QBO, it is shown how a zonal wind E shear favors aerosol confinement in the tropical pipe and a significant increase in their effective radius (+13 % with respect to W shear conditions). The net result is an increase in the downward cross-tropopause S flux over the tropics with dominant E shear conditions with respect to W shear periods (+0.61 Tg S yr −1 , +42 %, mostly due to enhanced aerosol gravitational settling) and a decrease over the extratropics (−0.86 Tg S yr −1 , −35 %, mostly due to decreased large-scale stratosphere–troposphere exchange of geoengineering sulfate). This translates into S-deposition changes that are significantly different under opposite QBO wind shears, with an E–W anomaly of +0.32 in the tropics and −0.67 Tg S yr −1 in the extratropics. Most online QBO schemes predict a significant change in the zonal wind periodicity, up to a blocked E shear condition for large enough injections, so that our results indicate an upper limit for the tropical increase in S deposition of 16.5 % relative to average conditions of unperturbed QBO periodicity and a correspondent extratropical S deposition decrease of 16 %.
Multidrug Sensitive Yeast Strains, Useful Tools for Chemical Genetics

The budding yeast Saccharomyces cerevisiae is a useful eukaryote model organism for application to chemical biology studies, for example, drug screening, drug evaluation, and target identification. To use yeast for chemical biology research, however, it has been necessary to construct yeast strains suitable for various compounds because of their high drug resistance. Hence, the deletion of all multidrug resistance genes except for those that are important for viability and for genetic experiments/manipulation could increase the drug sensitivity without influencing the transformation, mating, or sporulation effi -ciency. There are two major factors conferring multidrug resistance in S. cerevisiae : one is the drug efflux system and the other is the permeability barrier. We therefore constructed a strain which shows high sensitivity to multiple drugs by disrupting the drug efflux system using ATP-binding cassette transporters and suppressing the membrane barrier system by introducing an ERG6-inducible system. In this review, we discuss the construc tion of our multidrug-sensitive yeast strains and their application in chemical biology.
A 220 GHz finline mixer with ultra-wide instantaneous bandwidth

We describe the design and fabrication of a 220 GHz superconductor-insulator-superconductor (SIS) mixer with ultrawide IF bandwidth. The mixer is fabricated on a 100 µm thick quartz substrate, with planar circuit on-chip integration. The RF power is coupled to the tunnel junction via a unilateral finline taper and a slotline-to-microstrip transition. We used a double-stub tuning network to tune out the junction’s parasitic capacitance at a broad RF bandwidth, and matched the output impedance of the mixer to the input impedance of the IF amplifier (50 Ω) from 4–18 GHz using a 6-stage IF impedance-transformer. We have fabricated these devices and have measured good DC current-voltage (IV) characteristic curves. The heterodyne mixing performance of these devices is currently being measured, and we expect to present the results in the forthcoming ISSTT conference in March.
EFFECTS OF ULTRASOUND ON TECHNOLOGICAL PROPERTIES OF MEAT A REVIEW

Ultrasound is well known to become an efficient tool for various processes in the food industry. The process industry demands that operations be performed in the most efficient way with respect to processing cost, reduced processing time, lower energy consumption without a negative impact on product quality. Therefore, alternative novel technologies have tried to find solutions to reduce the total processing cost while maintaining or enhancing product quality . Power ultrasound has been recognized as a promising processing technique to replace or complement conventional thermal treatments in the food industry. Several processes such as emulsification, homogenization, extraction, crystallization, dewatering, low temperature pasteurization, degassing, defoaming, activation and inactivation of enzymes, particle size reduction and viscosity alteration have been applied efficiently in the food industry.This review surveyed recent literature focused on ultrasound technique used in meat industry. Ultrasound technology is applied in the meat industry mostly as a modern tool for carcasses evaluation but many of its uses are still being researched. The parameters, mechanisms and results of different experiments that have used low and high frequency ultrasound in meat industry were presented. Thus, the process parameters across in many experiments, as well as many applications in ultrasonic field was examined. The ultrasound effect on pH, the water-holding capacity, the tenderness of sonicated meat was presented in detail. The ultrasound effect on meat brining and tumbling was also considered.
Sticky Prices and Monetary Policy: Evidence from Disaggregated U.S. Data

This paper disentangles fluctuations in disaggregated prices due to macroeconomic and sectoral conditions using a factor-augmented vector autoregression estimated on a large data set. On the basis of this estimation, we establish eight facts: (1) Macroeconomic shocks explain only about 15% of sectoral inflation fluctuations; (2) The persistence of sectoral inflation is driven by macroeconomic factors; (3) While disaggregated prices respond quickly to sector-specific shocks, their responses to aggregate shocks are small on impact and larger thereafter; (4) Most prices respond with a significant delay to identified monetary policy shocks, and show little evidence of a "price puzzle," contrary to existing studies based on traditional VARs; (5) Categories in which consumer prices fall the most following a monetary policy shock tend to be those in which quantities consumed fall the least; (6) The observed dispersion in the reaction of producer prices is relatively well explained by the degree of market power; (7) Prices in sectors with volatile idiosyncratic shocks react rapidly to aggregate monetary policy shocks; (8) The sector-specific components of prices and quantities move in opposite directions.
Item Response Theory Scaling with Heterogeneous Populations.

Tools used in scaling proficiency scores from the Second International Assessment of Educational Progress (IAEP) are described. The second IAEP study, conducted in 1991, was an international comparative study of the mathematics and science skills of samples of 9and 13-year-old students from 20 countries. This paper focuses on part of the second stage of data analysis, work done in creating a unique scale for all the participating populations, that is, creating reference populations, scaling methodology, and linkage of 9and 13-year-old populatiol.b. All populations contributed to four combined reference populations, superpopulations, one for each age group by mathematics and science combination. The item response theory scaling model is the three-parameter logistic model. Linking was accomplished through a small set of common items included in the 9and 13-year-old assessments in each subject area. Results show that even if on an item-by-item basis the equating gives results that are not ideal, when all items are taken into account, student proficiency scores estimated with both sets of item parameter estimates can be considered to be on the same scale. Results further indicate that no information has been lost as a result of using one set of item parameter estimates over another. Fourteen tables and 16 figures present analysis data.

Salt-related Converted Wave Modelling and Imaging Study

Salt-related converted waves (C-waves) can be significant in conventional marine data. We explore the elimination of high-amplitude C-waves from the base of salt reflection as a way to improve subsalt imaging. We propose a dual-leg 3D acoustic modelling method to provide guidance for salt-related C-wave artifact identification and removal. Real data studies are presented to show the artifacts removed through pre-migration adaptive subtraction and post-migration Vector Offset Output RTM stacking. Additionally, we study dual flood RTM imaging for feasibility of using C-wave energies to aid in base of salt interpretation.
