    2013-01-01

    AIDA – the EU-funded project bringing together more than 80 institutes worldwide – aims at developing new detector solutions for future accelerators. Among the highlights reported at AIDA’s recent annual meeting in Frascati was the completion of an impressive calorimeter test beam programme, conducted by the CALICE collaboration over the past two years at CERN’s PS and SPS beam lines.   The CALICE tungsten calorimeter prototype under test at CERN. This cubic-metre hadron calorimeter prototype has almost 500,000 individually read-out electronics channels – more than all the calorimeters of ATLAS and CMS put together. Calorimeter development in AIDA is mainly motivated by experiments at possible future electron-positron colliders, namely ILC or CLIC. The physics requirements of such future machines demand extremely high-performance calorimetry. This is best achieved using a finely segmented system that reconstructs events using the so-called pa...

  4. The Lo Aguirre research reactor refurbishment

    International Nuclear Information System (INIS)

    A description is given of the main work which had to be performed on the experimental reactor of the Lo Aguirre nuclear power plant (RECH-2), following which it recently came into operation. In particular, an outline is given of the main changes and improvements made with regard to reactor physics calculations, the systems and components in the facility, and repair of existing fuel elements. Special importance was attached to the definition, application and meeting of nuclear safety requirements and the implementation of a consistent quality assurance programme. Certain aspects of the work performed, by virtue of the scope and importance of the tasks involved, resulted in clear improvements to and modernization of the facility - for example, the construction of a new control room, the construction of a computerized radiation protection and surveillance control room, the reconstruction of the primary coolant circuit, the complete refitting of reactor instrumentation to incorporate a computerized data acquisition system, the redesign and construction of reactor water treatment plants, improvements in experimental devices and the design and construction of new experimental devices. The reactor, construction of which was resumed in 1986, attained criticality on 6 September 1989 using the HEU fuel available. We are now at the stage of characterizing the reactor by measuring process and nuclear parameters prior to commencing power operation

  5. Status of AIDA and JAS 3

    International Nuclear Information System (INIS)

    AIDA (Abstract Interfaces for Data Analysis) project [1] is relatively new. It was conceived during HepVis-99 workshop in Orsay (http://www.lal.in2p3.fr/HEPVis99). The goals of the AIDA project are to define abstract interfaces for common physics analysis objects, such as histograms, ntuples, fitters, IO etc. The adoption of these interfaces should make it easier for physicists to use different tools without having to learn new interfaces or change all of their code. Additional benefits will be interoperability of AIDA compliant applications (for example by making it possible for applications to exchange analysis objects via XML). Also by bringing together the authors of a number of different applications we expect to gain deeper insight into the strengths and weaknesses of different applications, and to improve collaboration between different authors. Currently AIDA is distributed with bindings for C++ and Java. Since AIDA defines only abstract interfaces, a concrete implementation is needed to use AIDA. The following tools are currently available with support for AIDA: Anaphe [2] and OpenScientist [3] are written in C++, JAIDA/JAS [4] [5] written in Java. JAIDA is a Java implementation of AIDA, it can be used as a stand-alone package or together with some analysis tool (like JAS). JAIDA is also distributed with AIDA-JNI package that allows any C++ program written using the C++ AIDA interfaces to be linked to any Java implementation of AIDA. This way C++ programs can take advantage of the multi-threaded, cross-platform graphical capabilities of Java, and of the JAIDA implementation of AIDA in particular

  9. AIDA Asia. Artificial Insemination Database Application

    International Nuclear Information System (INIS)

    The objectives of AIDA (Artificial Insemination Database Application) and its companion GAIDA (Guide to AI Data Analysis) are to address two major problems in on-farm research on livestock production. The first is the quality of the data collected and the second is the intellectual rigor of the analyses and their associated results when statistically testing causal hypotheses. The solution is to develop a data management system such as AIDA and an analysis system such as GAIDA to estimate parameters that explain biological mechanisms for on-farm application. The system uses epidemiological study designs in the uncontrolled research environment of the farm, uses a database manager (Microsoft Access) to handle data management issues encountered in preparing data for analysis, and then uses a statistical program (SYSTAT) to do preliminary analyses. These analyses enable the researcher to have better understanding of the biological mechanisms involved in the data contained within the AIDA database. Using GAIDA as a guide, this preliminary analysis helps to determine the strategy for further in-depth analyse

    2016-07-01

    The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint cooperation between European and US space agencies that consists of two separate and independent spacecraft that will be launched to a binary asteroid system, the near-Earth asteroid Didymos, to assess the possibility of deflecting an asteroid trajectory by using a kinetic impactor. The European Asteroid Impact Mission (AIM) is under Phase A/B1 study at ESA from March 2015 until summer 2016. AIM is set to rendez-vous with the asteroid system a few months prior to the impact by the US Double Asteroid Redirection Test (DART) spacecraft to fully characterize the smaller of the two binary components. AIM is a unique mission as it will be the first time that a spacecraft will investigate the surface, subsurface, and internal properties of a small binary near Earth asteroid. In addition it will perform various important technology demonstrations that can serve other space missions: AIM will release a set of CubeSats in deep space and a lander on the surface of the smaller asteroid and for the first time, deep-space inter-satellite linking will be demonstrated between the main spacecraft, the CubeSats, and the lander, and data will also be transmitted from interplanetary space to Earth by a laser communication system. The knowledge obtained by this mission will have great implications for our understanding of the history of the Solar System. Small asteroids are believed to result from collisions and other processes (e.g., spinup, shaking) that made them what they are now. Having direct information on their surface and internal properties will allow us to understand how these processes work and transform these small bodies as well as, for this particular case, how a binary system forms. So far, our understanding of the collisional process and the validation of numerical simulations of the impact process rely on impact experiments at laboratory scales. With DART, thanks to the characterization of the

    The Asteroid Impact Deflection, AIDA, mission is composed of a kinetic impactor, DART and an observer, the Asteroid Impact Monitor, AIM, carrying among other payload a surface package, MASCOT2 (MSC2). Its proposed concept is based on the MASCOT lander onboard the HAYABUSA2 Mission (JAXA) to near-Earth asteroid (162173) Ryugu. MASCOT is a compact platform ('shoe box size') carrying a suite of 4 scientific instruments and has a landed mass of ~10kg. Equipped with a mobility mechanism, the MASCOT lander is able to upright and relocate on the targeted asteroid; thus providing in-situ data at more than one site. In the context of the AIDA Mission, the MASCOT2 lander would be carried by the AIM spacecraft and delivered onto Didymoon, the secondary object in the (65803) Didymos binary near-Earth asteroid system. Since the mission objectives of the AIM mission within the joint AIDA mission concept differ from JAXA's sample return mission HAYABUSA2, several design changes need to be studied and implemented. To support one of the prime objectives of the AIM mission, the characterization of the bulk physical properties of Didymoon, the main scientific payload of MSC2 is a low-frequency radar (LFR) to investigate the internal structure of the asteroid moon. Since the total science payload on MASCOT2 is limited to approximately 2.3 kg, the mass remaining for a suite of other experiments is in the range of 0.1 to 0.5 kg per instrument. Further requirements have a significant impact on the MSC2 design which will be presented. Among these are the much longer required operational lifetime than for MASCOT on HAYABUSA2, and different conditions on the target body such as an extremely low gravity due to its small size of Ø_[Didymoon] ~ 150m.

    The Asteroid Impact Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation using a kinetic impactor. AIDA is a joint ESA-NASA cooperative project, consisting of the NASA Double Asteroid Redirection Test (DART) mission, which provides the kinetic impactor, and the ESA Asteroid Impact Mission (AIM) rendezvous spacecraft. DART is a Phase A study supported by NASA, and AIM is a Phase B1 study supported by ESA. The AIDA target is the near-Earth binary asteroid 65803 Didymos, which will make a close approach to Earth in October, 2022. The DART spacecraft is designed to impact the Didymos secondary at ~6 km/s and deflect its trajectory, changing the orbital period of the binary. This change can be measured by Earth-based optical and radar observations. The primary goals of AIDA are to (1) perform a full-scale demonstration of asteroid deflection by kinetic impact; (2) measure the resulting deflection; and (3) validate and improve models for momentum transfer in high-speed impacts on an asteroid. The combined DART and AIM missions will provide the first measurements of momentum transfer efficiency from a kinetic impact at full scale on an asteroid, where the impact conditions of the projectile are known, and physical properties and internal structures of the target asteroid are also characterized. In addition to a predicted 4.4 minute change in the binary orbit period, assuming unit momentum transfer efficiency, the DART kinetic impact is predicted to induce forced librations of the Didymos secondary of possibly several degrees amplitude. Models predict the impact will create a 6-17 meter diameter crater, depending on target physical properties, and it will release a volume of particulate ejecta that may be directly observable from Earth or even resolvable as a coma or an ejecta tail by ground-based telescopes. Current simulations of the DART impact provide predictions for momentum transfer, crater size, and

    International Nuclear Information System (INIS)

    Artificial Insemination Database Application (AIDA-Asia) is a computer application to store and analyze information from AI Services (farms, females, inseminated, semen, estrus characteristics, inseminator and pregnancy diagnosis data). The need for such an application arose during a consultancy undertaken by the author for the International Atomic Energy Agency (IAEA, Vienna) under the framework of its Regional Co-operative Agreement for Asia and the Pacific (RCA) which is implementing a project on 'Improving Animal Productivity and Reproductive Efficiency' (RAS/5/035). The detailed specifications for the application were determined through a Task Force Meeting of National Consultants from five RCA Member States, organized by the IAEA and held in Sri Lanka in April 2001. The application has been developed in MS Access 2000 and Visual Basic for Applications (VBA) 6.0. However, it can run as a stand-alone application through its own executable files. It is based on screen forms for data entry or editing of information and command buttons. The structure of the data, the design of the application and VBA codes cannot be seen and cannot be modified by users. However, the designated administrator of AIDA-Asia in each country can customize it

  5. AIDA-1 Moves out of the Postsynaptic Density Core under Excitatory Conditions.

    Directory of Open Access Journals (Sweden)

    Ayse Dosemeci

    Full Text Available AIDA-1 is highly enriched in postsynaptic density (PSD fractions and is considered a major component of the PSD complex. In the present study, immunogold electron microscopy was applied to determine localization as well as the activity-induced redistribution of AIDA-1 at the PSD using two antibodies that recognize two different epitopes. In cultured rat hippocampal neurons under basal conditions, immunogold label for AIDA-1 is mostly located within the dense core of the PSD, with a median distance of ~30 nm from the postsynaptic membrane. Under excitatory conditions, such as depolarization with high K+ (90 mM, 2 min or application of NMDA (50 μM, 2 min, AIDA-1 label density at the PSD core is reduced to 40% of controls and the median distance of label from the postsynaptic membrane increases to ~55 nm. The effect of excitatory conditions on the postsynaptic distribution of AIDA-1 is reversed within 30 minutes after returning to control conditions. The reversible removal of AIDA-1 from the PSD core under excitatory conditions is similar to the redistribution of another abundant PSD protein, SynGAP. Both SynGAP-alpha1 and AIDA-1 are known to bind PSD-95. Activity-induced transient translocation of these abundant proteins from the PSD core could promote structural flexibility, vacate sites on PSD-95 for the insertion of other components and thus may create a window for synaptic modification.

    2016-07-01

    Introduction: The Asteroid Impact Deflection Assessment (AIDA) mission is a joint project of ESA and NASA with two independent spacecraft. ESA's contribution is an observer satellite called Asteroid Impact Mission (AIM, [1]), and NASA's contribution is a projectile called Double Asteroid Redirection Test (DART, [2]). The target of the mission is a near-Earth binary asteroid system (65803) Didymos. The aim is to study the possibility of deflecting an asteroid by using a kinetic impactor, as well as to characterize the internal properties of the target and test various relevant technologies for other missions. The design is that the DART would impact the secondary of the binary system and AIM would characterize the target asteroid, observe the impact event and measure the changes in the relative orbit after the impact. Impact modeling will be used to interpret the results of the AIDA impact event. There are numerous impact simulation codes, which are planned to be used to understand the AIDA impact results. Therefore an international benchmarking program is ongoing for the comparison of the results of various codes on the defined test cases [3]. We will present the results of the test cases performed by iSALE hydrocode. Modeling: In this work we use the iSALE-2D shock physics code [4], which is based on the SALE hydrocode solution algorithm [5]. To simulate hypervelocity impact processes in solid materials SALE was modified to include an elastoplastic constitutive model, fragmentation models, various EOS, and multiple materials [6, 7]. More recent improvements include a modified strength model [8] and a porosity compaction model [4, 9]. References: [1] Michel P. et al., 2016, ASR, submitted [2] Cheng A.

    Full Text Available El conquistador español de origen vascongado, Lope de Aguirre, redactó en Venezuela (1561 varias cartas dirigidas a Coronay a sus representantes venezolanos. La más importante de ellas fue la enviada al monarca Felipe II. En ella, Aguirre adoptó un peculiar tono burlón y profético, y mezcló ideas jurídicas y teológicas relacionadas con la posesión de América. A diferencia de la imagen de Aguirre como personaje irracional divulgada en la documentación y la historiografía de la época, este trabajo descubre la lógica subyacente en su carta al monarca destinada a defender la posición política de Aguirre.During the summer of inVenezuela, the rebel Lope de Aguirre wrote several letters addressed to his political enemies on both sides of the Atlantic. The most important of these documents was the letter sent to Philip II, king of Spain. In this letter, Aguirre incorporated legal terminology while simultaneously adopting a burlesque and prophetic tone to effectively address the Spanish possession of America. Contrary to the predominant image of Aguirre as an irrational being in the documents and the historiography of that period, this paper shows the rhetorical logic of Aguirre´s famous letter. Therefore, the letter is best understood as an attempt to justify a political position.

    2016-07-01

    The Asteroid Impact & Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor. AIDA is a joint ESA-NASA cooperative project, consisting of the ESA Asteroid Impact Mission (AIM) rendezvous mission and the NASA Double Asteroid Redirection Test (DART) mission. The AIDA target is the near-Earth binary asteroid 65803 Didymos, which will make an unusually close approach to Earth in October, 2022. The DART spacecraft is designed to impact the Didymos secondary at 7 km/s and demonstrate the ability to modify its trajectory through momentum transfer. DART and AIM are currently Phase A studies supported by NASA and ESA respectively. The primary goals of AIDA are (1) perform a full-scale demonstration of the spacecraft kinetic impact technique for deflection of an asteroid; (2) measure the resulting asteroid deflection, by targeting the secondary member of a binary NEO and measuring the resulting changes of the binary orbit; and (3) study hyper-velocity collision effects on an asteroid, validating models for momentum transfer in asteroid impacts based on measured physical properties of the asteroid surface and sub-surface, and including long-term dynamics of impact ejecta. The primary DART objectives are to demonstrate a hyper-velocity impact on the Didymos moon and to determine the resulting deflection from ground-based observations. The DART impact on the Didymos secondary will change the orbital period of the binary which can be measured by supporting Earth-based optical and radar observations. The baseline DART mission launches in December, 2020 to impact the Didymos secondary in September,2022. There are multiple launch opportunities for DART leading to impact around the 2022 Didymos close approach to Earth. The AIM spacecraft will be launched in Dec. 2020 and arrive at Didymos in spring, 2022, several months before the DART impact. AIM will characterize the Didymos binary system

The AIDA target is the near-Earth binary asteroid 65803 Didymos, which will make an unusually close approach to Earth in October, 2022. The ~300-kg DART spacecraft is designed to impact the Didymos secondary at 7 km/s and demonstrate the ability to modify its trajectory through momentum transfer. DART and AIM are currently Phase A studies supported by NASA and ESA respectively. The primary goals of AIDA are (1) perform a full-scale demonstration of the spacecraft kinetic impact technique for deflection of an asteroid, by targeting an object larger than ~100 m and large enough to qualify as a Potentially Hazardous Asteroid; (2) measure the resulting asteroid deflection, by targeting the secondary member of a binary NEO and measuring the period change of the binary orbit; (3) understand the hyper-velocity collision effects on an asteroid, including the long-term dynamics of impact ejecta; and validate models for momentum transfer in asteroid impacts, based on measured physical properties of the asteroid surface and sub-surface. The primary DART objectives are to demonstrate a hyper-velocity impact on the Didymos moon and to determine the resulting deflection from ground-based observatories. The DART impact on the Didymos secondary will cause a measurable change in the orbital period of the binary.

    From 2010 to 2014 the EU funded AIDA project established in one of its work packages (WP3) a network of groups working collaboratively on advanced 3D integration of electronic circuits and semiconductor sensors for applications in particle physics. The main motivation came from the severe requirements on pixel detectors for tracking and vertexing at future Particle Physics experiments at LHC, super-B factories and linear colliders. To go beyond the state-of-the-art, the main issues were studying low mass, high bandwidth applications, with radiation hardness capabilities, with low power consumption, offering complex functionality, with small pixel size and without dead regions. The interfaces and interconnects of sensors to electronic readout integrated circuits are a key challenge for new detector applications.

    2015-01-01

    This work addresses the research and development of an innovative optimization kernel applied to analog integrated circuit (IC) design. Particularly, this works describes the modifications inside the AIDA Framework, an electronic design automation framework fully developed by at the Integrated Circuits Group-LX of the Instituto de Telecomunicações, Lisbon. It focusses on AIDA-CMK, by enhancing AIDA-C, which is the circuit optimizer component of AIDA, with a new multi-objective multi-constraint optimization module that constructs a base for multiple algorithm implementations. The proposed solution implements three approaches to multi-objective multi-constraint optimization, namely, an evolutionary approach with NSGAII, a swarm intelligence approach with MOPSO and stochastic hill climbing approach with MOSA. Moreover, the implemented structure allows the easy hybridization between kernels transforming the previous simple NSGAII optimization module into a more evolved and versatile module supporting multiple s...

    Ankyrin repeat and sterile alpha motif domain-containing protein 1B (ANKS1B, also known as AIDA-1) is a major component of the postsynaptic density (PSD) in excitatory neurons where it concentrates at the electron-dense core under basal conditions and moves out during activity. This study investigates the molecular mechanism underlying activity-induced displacement of AIDA-1. Experiments with PSD fractions from brain indicate phosphorylation of AIDA-1 upon activation of endogenous CaMKII. Immuno-electron microscopy studies show that treatment of hippocampal neurons with NMDA results in an ~ 30 nm shift in the median distance of the AIDA-1 label from the postsynaptic membrane, an effect that is blocked by the CaMKII inhibitor tatCN21. CaMKII-mediated redistribution of AIDA-1 is similar to that observed for SynGAP. CaMKII-mediated removal of two abundant PSD-95-binding proteins from the PSD core during activity is expected to initiate a molecular reorganization at the PSD. PMID:27477489

    2014-01-01

    Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored "virtual diabetic patients" on the internet or create new "patients" with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online's functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.

    Dinosaur footprints were traced at San Juan Raya, an important site in Mexico, a world fossil site. This site is found at South-west of the State of Puebla, within the Biosphere Reserve of Tehuacan-Cuitcatlán, to the southwest of the Tehuacan valley. These footprints were recorded by tracing them on transparent paper at Barranca Agua Nueva, at point 18°18.56´N 97°37´W. Using Jacob´s staff a stratigraphic register was generated from 50 m ascending and descending in stratigraphically direction from the bed where footprints were founded. Bivalbes, nerineas, shell fragments, and trigonias were founded in this sequence as well as cross bedding of clays and fine grain sand, some which display ripples. Fifty two footprints were recorded and five different tracks identified, observing two different sizes. The tracks of dinosaur footprints present the common Teropode ichnites. The succession where dinosaur footprints have been found, are interpreted as a peritidal environment. This investigation contributes to an eco-tourism project of San Juan Raya.

    Full Text Available AIDA1 links persistent chemical signaling events occurring at the neuronal synapse with global changes in gene expression. Consistent with its role as a scaffolding protein, AIDA1 is composed of several protein-protein interaction domains. Here we report the NMR structure of the carboxy terminally located phosphotyrosine binding domain (PTB that is common to all AIDA1 splice variants. A comprehensive survey of peptides identified a consensus sequence around an NxxY motif that is shared by a number of related neuronal signaling proteins. Using peptide arrays and fluorescence based assays, we determined that the AIDA1 PTB domain binds amyloid protein precursor (APP in a similar manner to the X11/Mint PTB domain, albeit at reduced affinity (∼10 µM that may allow AIDA1 to effectively sample APP, as well as other protein partners in a variety of cellular contexts.

    The Raya valley is located in the northern part of Ethiopia. The study area is connected to the Ethiopian rift system and bounded by the Ethiopian plateau to the west and Cherecher Mountain to the east. The study area is characterized by its semiarid climate. In order to investigate isotopic characteristics of different water bodies and groundwater recharge, water samples were collected in the summer rainy season and analysed for stable isotopes of oxygen and hydrogen by a laser based liquid water isotope analyser. Most of the groundwater samples are plotted just below the LMWL, which indicates that the origin is meteoric water and affected by secondary evaporation. There are highly depleted water samples in the eastern side of the study area, which could be attributed to the existence of palaeowater. Groundwater is mainly recharged by rain water and intermittent rivers. Open water bodies (the lake Ashenge and Gerjale swamp area) show enrichment due to high rate of evaporation. Isotopically the flood water in the highland aarea is depleted as a result of high rate of rainfall, high humidity and low rate of evaporation. (author)

    Full Text Available There are many locations for traditional gold mining in Indonesia. One of these is in Murung Raya District, Central Kalimantan Province. Mining activities involving the application of traditional gold processing technology have a high potential to pollute the environment, especially surface water. Therefore, this study aims to determine the impact of gold mining and processing on surface water quality around the mine site. Based on the results of field surveys and laboratory analysis, our data shows that the concentration of mercury (Hg and Cyanide (CN has reached 0.3 mg/L and 1.9 mg/L, respectively, in surface water. These values exceed the drinking water quality standards of Indonesia and WHO. Many people who live in the mining area use surface water for daily purposes including drinking, cooking, bathing and washing. This scenario is very dangerous because the effect of surface water contamination on human health cannot be immediately recognized or diagnosed. In our opinion the dissemination of knowledge regarding the treatment of gold mining wastewater is urgently required so that the quality of wastewater can be improved before it is discharged into the environment.

    Introduction AIDA is an interactive educational diabetes simulator that has been available without charge via the Internet for over 12 years. Recent articles have described the incorporation of a novel generic model of insulin absorption into AIDA as a way of enhancing its capabilities. The basic model components to be integrated have been overviewed, with the aim being to provide simulations of regimens utilizing insulin analogues, as well as insulin doses greater than 40 IU (the current upper limit within the latest release of AIDA [v4.3a]). Some preliminary calculated insulin absorption results have also recently been described. Methods This article presents the first simulated plasma insulin profiles from the integration of the generic subcutaneous insulin absorption model, and the currently implemented model in AIDA for insulin disposition. Insulin absorption has been described by the physiologically based model of Tarín and colleagues. A single compartment modeling approach has been used to specify how absorbed insulin is distributed in, and eliminated from, the human body. To enable a numerical solution of the absorption model, a spherical subcutaneous depot for the injected insulin dose has been assumed and spatially discretized into shell compartments with homogeneous concentrations, having as its center the injection site. The number of these compartments will depend on the dose and type of insulin. Insulin inflow arises as the sum of contributions to the different shells. For this report the first bench testing of plasma insulin determinations has been done. Results Simulated plasma insulin profiles are provided for currently available insulin preparations, including a rapidly acting insulin analogue (e.g., lispro/Humalog or aspart/Novolog), a short-acting (regular) insulin preparation (e.g., Actrapid), intermediate-acting insulins (both Semilente and neutral protamine Hagedorn types), and a very long-acting insulin analogue (e.g., glargine/Lantus), as

    Full Text Available The poetry of the Guatemalan poet Aida Toledo, from its beginning, breaks away from the masculine and feminine images created and recreated through centuries by the owner of words and power, man. Toledo, as a consequence of her reflections on gender, questions, changes and pulverizes certain qualities considered to be unique and essential in defining each of the sexes. The poet starts with the Greek myths, as she considerers them to be the sacred pillars in building the Western Culture. Aida Toledo, not satisfied with using the sword of extermination against the eternal masculine and feminine values, uses the ashes from that fire as fertilizer to sprout new life, a life that time and space will shape into new beings, new male and female Minotaur.La poesía de la escritora guatemalteca Aída Toledo, desde sus inicios, rompe con las imágenes masculinas y femeninas creadas y recreadas a través de los siglos, por el dueño de la palabra y el poder, el hombre. Toledo, como consecuencia de sus reflexiones de género, cuestiona, pulveriza y cambia ciertas cualidades y mitos considerados únicos y esenciales en la definición de cada uno de los sexos. La poeta empieza con los mitos griegos, por considerarlos sagrados pilares sobre los cuales se construye la cultura occidental. Aida Toledo no se conforma con empuñar la espada de la exterminación contra los eternos valores masculinos y femeninos. Usa las cenizas de dicho fuego como abono para hacer brotar nueva vida, una vida a la que el tiempo y el espacio irán creando y moldeando nuevos seres. Es así como nace su Minotaura, la protagonista femenina que estaba ausente en el mito clásico.

    Tracking detectors in particle physics experiments allow a precise reconstruction of particle tracks close to the interaction point and the identification of primary and secondary decay vertices. In order to evaluate the performance of detector prototypes for future particle physics experiments — at hadron colliders (e.g. HL-LHC), flavour factories (e.g. SuperKEKB) or a future lepton collider (e.g. ILC) — under realistic conditions, a fast readout reference device, a telescope, with excellent resolution and modular configuration, is required. The successful development of a telescope with these characteristics was part of the EU-project EUDET, which is continued within the framework of the AIDA activity. One key addition to the telescope within AIDA is the implementation of at least one new reference plane dedicated to provide an adjustable geometry. This plane is realized with a hybrid pixel detector consisting of a sensor bump bonded to the ATLAS pixel readout chip FE-I4. Its masking capability allows t...

    The AIDA space mission, a collaborative effort between ESA and NASA, aims to characterize the near-Earth asteroid binary (65803) Didymos and to perform a kinetic impactor demonstration on the small moon of the binary system. Our study presents a multi-scale dynamical model of the ejecta cloud produced by a hypervelocity impact, which enables us to compute the ejecta properties at different spatial and time scales. This model is applied to the impact into the small moon of Didymos on October 2022 as considered by the AIDA mission. We model the process by including as much practical information as possible, e.g., the gravitational environment influenced by the non-spherical shapes of the bodies (based on the observed shape of the primary), the solar tides, and the solar radiation pressure. Our simulations show where and for how long the ejecta cloud evolves with time for the considered ejecta initial conditions. This information is used to assess the potential hazard to the ESA Asteroid Impact Mission (AIM) observing spacecraft and to determine the safest positions. This study is performed with support of the European Space Agency and in the framework of the NEOShield-2 project that has received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No 640351.

    Full Text Available On May 4, 2012, a new system, known as the AIDA (Advanced Information and Data Acquisition system for seismology, became operational as the primary tool to monitor, analyze, store and distribute seismograms from the Italian National Seismic Network. Only 16 days later, on May 20, 2012, northern Italy was struck by a Ml 5.9 earthquake that caused seven casualties. This was followed by numerous small to moderate earthquakes, with some over Ml 5. Then, on May 29, 2012, a Ml 5.8 earthquake resulted in 17 more victims and left about 14,000 people homeless. This sequence produced more than 2,100 events over 40 days, and it was still active at the end of June 2012, with minor earthquakes at a rate of about 20 events per day. The new AIDA data management system was designed and implemented, among other things, to exploit the recent huge upgrade of the Italian Seismic Network (in terms of the number and quality of stations and to overcome the limitations of the previous system.

    The moon of the near-Earth binary asteroid 65803 Didymos is the target of the Asteroid Impact and Deflection Assessment (AIDA) mission. This mission is a joint effort between NASA and ESA to investigate the effectiveness of a kinetic impactor in deflecting an asteroid. The mission is composed of two components: the NASA-led Double Asteroid Redirect Test (DART) that will impact Didymos' moon (henceforth Didymos B), and the ESA-led Asteroid Impact Mission (AIM) that will survey the Didymos system. Both will undertake proximity operations to characterize the physical and dynamical properties of the Didymos system that are of maximum importance in the joint AIDA mission to understand the factors at play when assessing the mometum transfer that follows DART's impact into Didymos B. Using much of ESA's Rosetta experience, the AIM mission will undertake proximity operations both before and after DART's impact. AIM's chracterization includes measuring the precise orbital configuration, masses, internal properties, surface geology and regolith properties of the primary and secondary, using visible and thermal imaging, radar measurements and radio science data. AIM will also release the small MASCOT-2 lander, as well as a suite of a CubeSats to help achieve these objectives. DART proximity observations include two phases of imaging. The first makes use of a suite of long range images that will add light curve data to what will be collected from Earth. These data will refine the orbit period of Didymos B, and provide constraints for modeling the shape of both Didymos A and B. The second phase begins just under an hour before impact when resolved imaging of the Didymos system provides further shape model constraints for the visble parts of both Didymos A and B, some possible constraints on the mass of Didymos B and key geological information of both objects and the impact site. In this presentation, we will summarize the proximity operations undertaken by both DART and AIM

    The Asteroid Impact Deflection and Assessment (AIDA) mission is composed of NASA's Double Asteroid Redirection Test (DART) mission and ESA's Asteroid Impact Monitor (AIM) rendezvous mission. The DART spacecraft is designed to impact the small satellite of near-Earth asteroid 65803 Didymos in October 2022, while the in-situ AIM spacecraft observes. AIDA's Modeling and Simulation of Impact Outcomes Working Group is tasked with investigating properties of the debris ejected from the impact. The orbital evolution of this ejecta has important implications for observations that the AIM spacecraft will take as well as for the safety of the spacecraft itself. Ejecta properties including particle sizes, bulk densities, and velocities all depend on the poorly-known physical properties of Didymos' moon. The moon's density, internal strength, and especially its porosity have a strong effect on all ejecta properties. Making a range of assumptions, we perform a suite of numerical simulations to determine the fate of the ejected material; we will use simulation predictions to optimize AIM observations and safety. Ultimately, combining AIM's observations of the ejecta with detailed numerical simulations will help constrain key satellite parameters.We use distinct types of numerical tools to explore ejecta properties based on additional target parameters (different forms of friction, cohesion), e.g., the shock physics code iSALE, smoothed particle hydrodynamics codes, and the granular code PKDGRAV. Given the large discrepancy between the 6 km/s impact speed of DART and the moon's 6 cm/s escape speed, a great challenge will be to determine properties of the low-speed ejecta. Very low-speed material relevant to the safety of the AIM spacecraft and its ability to conduct its observations may loft from the crater at late stages of the impact process, or from other locations far from the impact site due to seismic energy propagation. The manner in which seismic waves manifests in

    The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint ESA-NASA mission concept currently under study. AIDA has two components: the Double Asteroid Redirect Test (DART) is the US component designed to demonstrate a kinetic impactor, while the Asteroid Impact Mission (AIM) spacecraft is on station to do a thorough pre- and post-impact survey of the Didymos system.Members of the DART and AIM Investigation teams have been organized into several joint and independent working groups. While there is overlap in subject matter and membership between the groups, we focus here on the activities of the Observing Working Group.The first work by the group was undertaken during the spring of 2015, before DART entered Phase A. During this period Didymos made an apparition reaching roughly V ~ 20.5 in brightness, and our top priority was constraining which of two very different pole positions for the Didymos system was correct. Several telescopes in the 2–4-m aperture range around the world attempted observations. An observed mutual event allowed the one pole position to be ruled out. Didymos is now thought to be a low-obliquity, retrograde rotator, similar to many other asteroid binary systems and consistent with expectations from a YORP-driven origin for the satellite.We have begun planning for the 2017 apparition, occurring in the first half of the year. Didymos will be ~20% brighter at opposition than the 2015 apparition. Scaling from the successful observations with the 4.3-m Lowell Discovery Channel Telescope indicates that we will need telescopes at least 4 m (or larger, for some of the tasks, or at times longer before or after the opposition) in primary diameter for the advanced characterization in 2017.Currently, we have four goals for this apparition: 1) confirming the preferred retrograde pole position; 2) gathering data to allow BYORP-driven changes in the mutual orbit to potentially be determined by later observations; 3) establishing whether or not

    ASPECT (Asteroid Spectral Imaging Mission) is a part of AIDA/AIM project and aims to study the composition of the Didymos binary asteroid and the effects of space weathering and shock metamorphism in order to gain understanding of the formation and evolution of the Solar System. The joint ESA/NASA AIDA (Asteroid Impact & Deflection Assessment) mission to binary asteroid Didymos consists of AIM (Asteroid Impact Mission, ESA) and DART (Double Asteroid Redirection Test, NASA). DART is targeted to impact Didymos secondary component (Didymoon) and serve as a kinetic impactor to demonstrate deflection of potentially hazardous asteroids. AIM will serve as an observational spacecraft to evaluate the effects of the impact and resulting changes in the Didymos dynamic parameters. The AIM mission will also carry two CubeSat miniaturized satellites, released in Didymoon proximity. This arrangement opens up a possibility for secondary scientific experiments. ASPECT is one of the proposed CubeSat payloads. Whereas Didymos is a space-weathered binary asteroid, the DART impactor is expected to produce a crater and excavate fresh material from the secondary component (Didymoon). Spectral comparison of the mature surface to the freshly exposed material will allow to directly deter-mine space weathering effects. It will be also possible to study spectral shock effects within the impact crater. ASPECT will also demonstrate for the first time the joint spacecraft - CubeSat operations in asteroid proximity and miniature spectral imager operation in deep-space environment. Science objectives: 1. Study of the surface composition of the Didymos system. 2. Photometric observations (and modeling) under varying phase angle and distance. 3. Study of space weathering effects on asteroids (comparison of mature / freshly exposed material). 4. Study of shock effects (spectral properties of crater interior). 5. Observations during the DART impact. Engineering objectives: 1. Demonstration of Cube

    If all goes as planned, in the year 2020 a joint ESA and NASA mission will be launched that will rendezvous with the near-Earth binary asteroid system 65803 Didymos in the fall of 2022. The European component, the Asteroid Impact & Deflection Assessment (AIDA) spacecraft will arrive first and characterize the system, which consists of a ~800 m diameter primary and a ~160 m diameter secondary, orbiting a common center of mass at a semi-major axis distance of ~1200 m with a orbital period of 11.9 hr. Following system characterization, the AIDA spacecraft will remove to a safe distance while the NASA component, the 300 kg Double Asteroid Redirection Test (DART) spacecraft collides with the trailing edge of the secondary body (with respect to the binary's retrograde mutual orbit). Meanwhile, the AIDA spacecraft will conduct observations of this impact and its aftermath, specifically looking for changes made to the primary, the secondary, and their mutual orbit as a result of the DART collision. Of particular interest is the ballistic flight and final disposition of the ejecta produced by the impact cratering process, not just from the standpoint of scientific study, but also from the standpoint of AIDA spacecraft safety.In this study, we investigate a series of hypothetical DART impacts utilizing a semi-empirical, numerical impact ejecta plume model originally developed for the Deep Impact mission and designed specifically with impacts on small bodies in mind. The resulting excavated mass is discretized into 7200 individual tracer particles, each representing a unique combination of speed, mass, and ejected direction. The trajectory of each tracer is computed numerically under the gravitational influence of both primary and secondary, along with the effects of solar radiation pressure. Each tracer is followed until it either impacts a body or escapes the system, whereupon tracking is continued in the heliocentric frame using an N-body integrator. Various impact

    Full Text Available The homogeneous freezing of supercooled H2SO4/H2O solution droplets was investigated in the aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere of Forschungszentrum Karlsruhe. 24 freezing experiments were performed at temperatures between 189 and 235 K with aerosol particles in the diameter range 0.05 to 1 µm. Individual experiments started at homogeneous temperatures and ice saturation ratios between 0.9 and 0.95. Cloud cooling rates up to -2.8 K min-1 were simulated dynamically in the chamber by expansion cooling using a mechanical pump. Depending on the cooling rate and starting temperature, freezing threshold relative humidities were exceeded after expansion time periods between about 1 and 10 min. The onset of ice formation was measured with three independent methods showing good agreement among each other. Ice saturation ratios measured at the onset of ice formation increased from about 1.4 at 231 K  to about 1.75 at 189 K. The experimental data set including thermodynamic parameters as well as physical and chemical aerosol analysis provides a good basis for microphysical model applications.

    Full Text Available The homogeneous freezing of supercooled H2SO4/H2O solution droplets was investigated in the aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere of Forschungszentrum Karlsruhe. 24 freezing experiments were performed at temperatures between 194 and 235 K with aerosol particles in the diameter range 0.05 to 1 µm. Individual experiments started at homogeneous temperatures and ice saturation ratios between 0.85 and 0.95. Cloud cooling rates up to -2.8 K/min were simulated dynamically in the chamber by expansion cooling using a mechanical pump. Depending on the cooling rate and starting temperature, freezing threshold relative humidities were exceeded after expansion time periods between about 1 and 10 min. The onset of ice formation was measured with three independent methods showing good agreement among each other. Ice saturation ratios measured at the onset of ice formation increased from about 1.4 at 231 K to about 1.75 at 189 K. The experimental data set including thermodynamic parameters as well as physical and chemical aerosol analysis provides a good basis for microphysical model applications.

  2. A Parallel Controls Software Approach for PEP II: AIDA & Matlab Middle Layer

    The controls software in use at PEP II (Stanford Control Program - SCP) had originally been developed in the eighties. It is very successful in routine operation but due to its internal structure it is difficult and time consuming to extend its functionality. This is problematic during machine development and when solving operational issues. Routinely, data has to be exported from the system, analyzed offline, and calculated settings have to be reimported. Since this is a manual process, it is time consuming and error-prone. Setting up automated processes, as is done for MIA (Model Independent Analysis), is also time consuming and specific to each application. Recently, there has been a trend at light sources to use MATLAB as the platform to control accelerators using a 'MATLAB Middle Layer' (MML), and so called channel access (CA) programs to communicate with the low level control system (LLCS). This has proven very successful, especially during machine development time and trouble shooting. A special CA code, named AIDA (Accelerator Independent Data Access), was developed to handle the communication between MATLAB, modern software frameworks, and the SCP. The MML had to be adapted for implementation at PEP II. Colliders differ significantly in their designs compared to light sources, which poses a challenge. PEP II is the first collider at which this implementation is being done. We will report on this effort, which is still ongoing.

    Antinuclear antibodies (ANAs) are significant biomarkers in the diagnosis of autoimmune diseases in humans, done by mean of Indirect ImmunoFluorescence (IIF) method, and performed by analyzing patterns and fluorescence intensity. This paper introduces the AIDA Project (autoimmunity: diagnosis assisted by computer) developed in the framework of an Italy-Tunisia cross-border cooperation and its preliminary results. A database of interpreted IIF images is being collected through the exchange of images and double reporting and a Gold Standard database, containing around 1000 double reported images, has been settled. The Gold Standard database is used for optimization of a CAD (Computer Aided Detection) solution and for the assessment of its added value, in order to be applied along with an Immunologist as a second Reader in detection of autoantibodies. This CAD system is able to identify on IIF images the fluorescence intensity and the fluorescence pattern.

    Full Text Available Diabetes mellitus is a major, and increasing, global problem. However, it has been shown that, through good management of blood glucose levels (BGLs, the associated and costly complications can be reduced significantly. In this pilot study, Elman recurrent artificial neural networks (ANNs were used to make BGL predictions based on a history of BGLs, meal intake, and insulin injections. Twenty-eight datasets (from a single case scenario were compiled from the freeware mathematical diabetes simulator, AIDA. It was found that the most accurate predictions were made during the nocturnal period of the 24 hour daily cycle. The accuracy of the nocturnal predictions was measured as the root mean square error over five test days (RMSE5 day not used during ANN training. For BGL predictions of up to 1 hour a RMSE5 day of (±SD 0.15±0.04 mmol/L was observed. For BGL predictions up to 10 hours, a RMSE5  day of (±SD 0.14±0.16 mmol/L was observed. Future research will investigate a wider range of AIDA case scenarios, real-patient data, and data relating to other factors influencing BGLs. ANN paradigms based on real-time recurrent learning will also be explored to accommodate dynamic physiology in diabetes.

    The dynamics of the ejecta cloud that results from a binary asteroid impact is one of the tasks of the NEOShield-2 project, funded by the European Commission in its program Horizon 2020. Results from such an investigation will have great relevance to the Phase-A study of the AIDA space mission, a collaborative effort between ESA and NASA, which aims to perform a kinetic impactor demonstration. Our study presents a multi-scale dynamical model of the ejecta cloud produced by a hypervelocity impact, which enables us to check the behaviors of the ejecta at different spatial and time scales. This model is applied to the impact into the small moon of the binary Near- Earth asteroid (65803) Didymos on October 2022 as considered by the AIDA mission. We attempt to model the process by including as much practical information as possible, e.g., the gravitational environment influenced by the non-spherical shapes of the bodies based on observed shape of the primary), the solar tides, and the solar radiation pressure. Our simulations show the general patterns of motion of the ejecta cloud, which we use to assess the potential hazard to an observing spacecraft. We also look into the grain-scale dynamics of the ejecta during this process, which has influence on the re-accumulation of particles orbiting in the vicinity.

    Full Text Available The AIDA (Aerosol Interactions and Dynamics in the Atmosphere aerosol and cloud chamber of Forschungszentrum Karlsruhe can be used to test the ice forming ability of aerosols. The AIDA chamber is extensively instrumented including pressure, temperature and humidity sensors, and optical particle counters. Expansion cooling using mechanical pumps leads to ice supersaturation conditions and possible ice formation. In order to describe the evolving chamber conditions during an expansion, a parcel model was modified to account for diabatic heat and moisture interactions with the chamber walls. Model results are shown for a series of expansions where the initial chamber temperature ranged from −20°C to −60°C and which used desert dust as ice forming nuclei. During each expansion, the initial formation of ice particles was clearly observed. For the colder expansions there were two clear ice nucleation episodes. In order to test the ability of the model to represent the changing chamber conditions and to give confidence in the observations of chamber temperature and humidity, and ice particle concentration and mean size, ice particles were simply added as a function of time so as to reproduce the observations of ice crystal concentration. The time interval and chamber conditions over which ice nucleation occurs is therefore accurately known, and enables the model to be used as a test bed for different representations of ice formation.

    The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint cooperation between European and US space agencies that consists of two separate and independent spacecraft that will be launched to a binary asteroid system, the near-Earth asteroid Didymos, to test the kinetic impactor technique to deflect an asteroid. The European Asteroid Impact Mission (AIM) is set to rendezvous with the asteroid system to fully characterize the smaller of the two binary components a few months prior to the impact by the US Double Asteroid Redirection Test (DART) spacecraft. AIM is a unique mission as it will be the first time that a spacecraft will investigate the surface, subsurface, and internal properties of a small binary near-Earth asteroid. In addition it will perform various important technology demonstrations that can serve other space missions. The knowledge obtained by this mission will have great implications for our understanding of the history of the Solar System. Having direct information on the surface and internal properties of small asteroids will allow us to understand how the various processes they undergo work and transform these small bodies as well as, for this particular case, how a binary system forms. Making these measurements from up close and comparing them with ground-based data from telescopes will also allow us to calibrate remote observations and improve our data interpretation of other systems. With DART, thanks to the characterization of the target by AIM, the mission will be the first fully documented impact experiment at asteroid scale, which will include the characterization of the target's properties and the outcome of the impact. AIDA will thus offer a great opportunity to test and refine our understanding and models at the actual scale of an asteroid, and to check whether the current extrapolations of material strength from laboratory-scale targets to the scale of AIDA's target are valid. Moreover, it will offer a first check of the

    The proposed Asteroid Impact Deflection and Assessment (AIDA) mission includes NASA's Double Asteroid Redirection Test (DART), whose impact with the secondary of near-Earth binary asteroid 65803 Didymos is expected to liberate large amounts of ejecta. We present efforts within the AIDA Impact Simulation Working Group to comprehensively simulate the behavior of this impact ejecta as it moves through and exits the system. Group members at JPL, OCA, and UMD have been working largely independently, developing their own strategies and methodologies. Ejecta initial conditions may be imported from output of hydrocode impact simulations or generated from crater scaling laws derived from point-source explosion models. We started with the latter approach, using reasonable assumptions for the secondary's density, porosity, surface cohesive strength, and vanishingly small net gravitational/rotational surface acceleration. We adopted DART's planned size, mass, closing velocity, and impact geometry for the cratering event. Using independent N-Body codes, we performed Monte Carlo integration of ejecta particles sampled over reasonable particle size ranges, and over launch locations within the crater footprint. In some cases we scaled the number of integrated particles in various size bins to the estimated number of particles consistent with a realistic size-frequency distribution. Dynamical models used for the particle integration varied, but all included full gravity potential of both primary and secondary, the solar tide, and solar radiation pressure (accounting for shadowing). We present results for the proportions of ejecta reaching ultimate fates of escape, return impact on the secondary, and transfer impact onto the primary. We also present the time history of reaching those outcomes, i.e., ejecta clearing timescales, and the size-frequency distribution of remaining ejecta at given post-impact durations. We find large numbers of particles remain in the system for several

    Full Text Available Cirrus clouds and their impact on the Earth's radiative budget are subjects of current research. The processes governing the growth of cirrus ice particles are central to the radiative properties of cirrus clouds. At temperatures relevant to cirrus clouds, the growth of ice crystals smaller than a few microns in size is strongly influenced by the accommodation coefficient of water molecules on ice, αice, making this parameter relevant for cirrus cloud modeling. However, the experimentally determined magnitude of αice for cirrus temperatures is afflicted with uncertainties of almost three orders of magnitude and values for αice derived from cirrus cloud data lack significance so far. This has motivated dedicated experiments at the cloud chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere to determine αice in the cirrus-relevant temperature interval between 190 K and 235 K under realistic cirrus ice particle growth conditions. The experimental data sets have been evaluated independently with two model approaches: the first relying on the newly developed model SIGMA (Simple Ice Growth Model for determining Alpha, the second one on an established model, ACPIM (Aerosol-Cloud-Precipitation Interaction Model. Within both approaches, a careful uncertainty analysis of the obtained αice values has been carried out for each AIDA experiment. The results show no significant dependence of αice on temperature between 190 K and 235 K. In addition, we find no evidence for a dependence of αice on ice particle size or on water vapor supersaturation for ice particles smaller than 20 μm and supersaturations of up to 70%. The temperature averaged and combined result from both models is αice=0.6−0.4+0.4 which implies that αice may only exert a minor impact on cirrus clouds and their characteristics when compared to the

    Full Text Available Abstract Background In the continuing revision of Diagnostic and Statistical Manual (DSM-V “identity” is integrated as a central diagnostic criterion for personality disorders (self-related personality functioning. According to Kernberg, identity diffusion is one of the core elements of borderline personality organization. As there is no elaborated self-rating inventory to assess identity development in healthy and disturbed adolescents, we developed the AIDA (Assessment of Identity Development in Adolescence questionnaire to assess this complex dimension, varying from “Identity Integration” to “Identity Diffusion”, in a broad and substructured way and evaluated its psychometric properties in a mixed school and clinical sample. Methods Test construction was deductive, referring to psychodynamic as well as social-cognitive theories, and led to a special item pool, with consideration for clarity and ease of comprehension. Participants were 305 students aged 12–18 attending a public school and 52 adolescent psychiatric inpatients and outpatients with diagnoses of personality disorders (N = 20 or other mental disorders (N = 32. Convergent validity was evaluated by covariations with personality development (JTCI 12–18 R scales, criterion validity by differences in identity development (AIDA scales between patients and controls. Results AIDA showed excellent total score (Diffusion: α = .94, scale (Discontinuity: α = .86; Incoherence: α = .92 and subscale (α = .73-.86 reliabilities. High levels of Discontinuity and Incoherence were associated with low levels in Self Directedness, an indicator of maladaptive personality functioning. Both AIDA scales were significantly different between PD-patients and controls with remarkable effect sizes (d of 2.17 and 1.94 standard deviations. Conclusion AIDA is a reliable and valid instrument to assess normal and disturbed identity in adolescents. Studies for further

A spatial analysis is applied to determine the principal driving forces of the artificial surfaces changes. For this, different tools are in use in order to differentiate the land use and land cover changes or the driving forces. The changes were quantified by statistical technologies and images of CORINE Land Cover Project and the driving factors were analyzed by logistic regressions (generalized linear models) combining human and geophysics variables. Conclusions show the suitability of the employment of the information of CORINE Land Cover project, the significant selected independent variables, and the validity of the generalized linear models for the explanation of the land use and land cover change of a certain territory.

    Full Text Available Species of the family Pinnotheridae constitute an ideal group for morphometric studies due to their complex morphological adaptations. These adaptations respond to the selective pressure of a symbiotic life style. This study describes the relative growth and morphometric features of the symbiotic pea crab Austinixa aidae (associated with the ghost shrimp Callichirus major, from the sandy beaches in the southwest Atlantic, Brazil. Significant differences were detected in the biometric proportions, particularly the chelar propodus length and carapace width, of each sex. These dimensions were also related to the size at which the individuals reached morphological sexual maturity (5.1 mm of carapace width for both sexes. Males and females were 2.4 times wider than long, which corresponds to the principal adaptation developed by Austinixa species to live in cryptic environments. Moreover, juveniles were proportionally more rounded. The changes in the biometric proportions of carapace length and width of A. aidae were more pronounced in males and females, adaptations that facilitate roaming within the galleries of their hosts.Las especies de la familia Pinnotheridae constituyen un grupo ideal para la realización de estudios morfométricos, debido a sus complejas adaptaciones morfológicas. Estas adaptaciones son respuesta a la presión de selección debida a su vida simbionte. En este estudio se describió el crecimiento relativo y las características morfométricas del cangrejo simbionte Austinixa aidae (asociado con el camarón fantasma Callichirus major, de una playa de arena del Atlántico suroeste de Brasil. Se determinaron diferencias significativas en las proporciones biométricas de cada sexo, entre la longitud del propodio y ancho del caparazón. Estas dimensiones estuvieron relacionadas también con la talla en que los individuos muestran cambios morfológicos en su madurez sexual (5.1 mm de ancho del caparazón en ambos sexos. Los machos

At the beginning he had severe pain, and during the first hours after the accident progressive edema was evident. He arrived to our hospital 24 hours later, when purulent discharge and eritem was obvious. Intravenous antibiotics were initiated and three surgical debridements where performed during the following week. After the process was complete, a soft tissue defect was created on the internal malleolus (7 x 5 cm. Reconstruction was achieved using a reverse internal saphenous flap that evolved satisfactorily. Severe skin injuries caused by stingrays (Myliobatidae have been reported shortly in plastic surgery literature, because these lesions usually heal without surgical procedures.

    From March 1993 to October 1993, 20 consecutive, newly diagnosed acute promyelocytic leukemia (APL) patients from 13 Italian institutions entered in a pilot study named AIDA, combining all-trans retinoic acid (ATRA) with idarubicin (IDA). ATRA was administered orally beginning on the first day of induction at the dosage of 45 mg/m2/d until complete remission (CR), whereas IDA was administered intravenously at the dosage of 12 mg/m2/d on days 2, 4, 6, and 8 of the induction. Patients who achieved CR were consolidated with 3 courses of chemotherapy without ATRA; thereafter, they were followed up for molecular and hematologic CR. The median age was 35.3 years (range, 6.5 to 67.6 years); 8 patients were males and 12 females; 4 had the hypogranular variant of APL (M3v), and 4 (2 with M3v) presented with leukocyte counts > or = 10,000/microL. Molecular analysis for the promyelocytic leukemia-retinoic acid receptor alpha (PML-RAR alpha) hybrid gene at diagnosis was performed in 16 patients by means of reverse transcription-polymerase chain reaction (RT-PCR) analysis, and all were RT-PCR+ for the hybrid gene. In the remaining 4 patients, the cytogenetic study showed the presence of the t(15;17). After a median time of 36 days (range, 28 to 52 days) 18 (90%) patients achieved CR; the remaining 2 patients died 12 and 34 days after diagnosis from myocardial infarction caused by fungal myocarditis and from massive hemoptysis, respectively. ATRA syndrome was observed in only 2 patients, and, after the prompt discontinuation of ATRA and initiation of dexamethasone, both recovered from the syndrome. However, after recovering, 1 patient achieved CR, whereas the other died at day 34 because of massive hemoptysis; other side effects were very limited. At recovery from the third consolidation course, only 3 of 14 (21.4%) tested patients were RT-PCR+ for the PML-RAR alpha hybrid gene. Of these, 2 relapsed shortly afterwards; however, in the last patient, the PML-RAR alpha disappeared

Las hembras fueron proporcionalmente más grandes que los machos, aunque el crecimiento fue similar en ambos sexos (alométrico. Los embriones no presentaron diferencias sexuales significativas ni en talla ni en peso. La proporción sexual en adultos fue 2,4:1 (hembras-machos, mientras que en embriones esta proporción fue de 1:1. El 51,5% de machos presentó claspers desarrollados y calcificados y el 56,5% de las hembras estaban grávidas, presentando fecundidades entre 1 y 6 embriones, con tallas entre 3 y 19,5 cm, sugiriendo una talla de nacimiento entre 19 y 19,5 cm LT. La talla mediana de madurez de las hembras fue menor que la de machos (48,48 cm y 51,18 cm LT, respectivamente, y las hembras presentaron crías a partir de 44 cm LT. Los hábitos alimentarios de esta especie mostraron 30 ítems presa, con camarones de la familia Penaeidae, y especialmente Trachypenaeus sp. como alimento principal. La raya guitarra presentó diferencias significativas en la dieta de machos y hembras, y la amplitud de nicho indicó que es especialista en su dieta.

    Full Text Available Competition for food could be a major force driving changes in the community structure of skates (Rajidae subjected to fishing exploitation. Under this hypothesis, small skates are released from competition with larger skates after fishing has depleted the larger species. Here, we compare the abundance patterns of two sympatric skates with similar niches but different life histories, Bathyraja albomaculata (larger and slow-reproducing and Bathyraja macloviana (smaller and faster-reproducing, before (1971, 1978 and after (1998-2004 a 108% increase in industrial bottom trawling on the southeastern South American shelf in order to test the prediction that B. macloviana should competitively exclude B. albomaculata after the increase in fishing mortality. In 1971 and 1978, there was no relationship between the abundance of both species, indicating that they coexisted over large scales. In 1998-2004, the relationship between the abundances of these skates was bell-shaped, indicating that both species increased in abundance at low densities until peaking, after which B. albomaculata decreased when B. macloviana became more abundant, consistent with resource competition. We tested whether food may be a potential limiting resource by comparing the diet of both species. The two species consumed mostly polychaetes, differing only in the consumption of polychaetes from the family Nephthyidae, which was much higher for B. macloviana. Bathyraja macloviana could replace B. albomaculata at high densities when food resources may become scarce. These results support the hypothesis that competition release is an important factor explaining the changes in skate communities in overexploited areas.La competencia por el alimento podría ser una fuerza importante detrás de los cambios en la estructura de las comunidades de rayas (Rajidae bajo explotación pesquera. Según esta hipótesis, las rayas pequeñas son liberadas de la competencia por las rayas de mayor tama

    Heating a mixture of alpha-aryl ketone with (R)-phenylglycinol produces a mixture of imine and 1,3-dioxazolidine. Treatment of this mixture with trimethylsilyl cyanide followed by transformation of nitrile to ester gives Strecker-type reaction products. The diastereoselectivity of the generated alpha-amino esters is from 2/1 to 7/1, and the (R,S)isomer is found as the major product. The (R,S) and (R,R)isomers can be separated by conversion to their N-Cbz or cyclization derivatives. Using this methodology, four antagonists of metabotropic glutamate receptors, (S)-alphaM4CPG, (S)-MPPG, (S)-AIDA, and (S)-APICA, are synthesized. PMID:11674092

The electric rays obtained were separate by sex, weighed and measured; the development of reproductive stage was identified by external and internal characteristics. The reproductive condition was determinate by (gonadosomatic GSI and hepatosomatic HSI indexes and the size at sexual maturity (l50%. The results showed that the GSI has one peak at year between September and December when probably the copulation carried out, the HSI presented its highest value in January, which corresponds to the end of the reproductive period. The size at sexual maturity was 32.2 cm in females and it was between 20.2 and 22.9 cm in males. We propose that the gestation period extends during four months, starting with the birth of individuals in February and finishing in April.

However, little is known of its life history parameters in this region. In this study, a total of 900 specimens were collected from February 2006 to December 2008 to determine the reproductive parameters needed for population assessments by means of ecological risk assessments or demographic analysis. Results suggested that females of D. americana reproduce annually, with a gestation of 7-8 months. The reproductive cycle of females is asynchronous, with ovulation and parturition occurring throughout the year. Females and males matured at 764 and 517 mm disc width (DW50 respectively. D. americana has one of the highest fecundity among dasyatids, from 2 to 7 embryos, with a sex ratio of embryos of 1:1. A linear relationship between maternal DW and fecundity was estimated, the larger females contain more embryos. The status of the population of D. americana is a cause of concern in the southern gulf of Mexico due to its high frequency of capture in artisanal fisheries and its apparently low biological productivity.La raya látigo americana Dasyatis americana (Hildebrand & Schroeder, 1928, conocida como balá en México, es el elasmobranquio más capturado y desembarcado por flotas artesanales en el sur del golfo de México.

    Two hundred fifty-three patients with newly diagnosed acute promyelocytic leukemia (APL) were eligible to enter the multicentric GIMEMA-AIEOP "AIDA" trial during the period July 1993 to February 1996. As a mandatory prerequisite for eligibility, all patients had genetic evidence of the specific t(15;17) lesion in their leukemic cells confirmed by karyotyping or by reverse transcription-polymerase chain reaction (RT-PCR) of the PML/RAR alpha fusion gene (the latter available in 247 cases). Median age was 37.8 years (range, 2.2 to 73.9). Induction treatment consisted of oral all-trans retinoic acid (ATRA), 45 mg/m2/d until complete remission (CR), given with intravenous Idarubicin, 12 mg/m2/d on days 2, 4, 6, and 8. Three polychemotherapy cycles were given as consolidation. Hematologic and molecular response by RT-PCR was assessed after induction and after consolidation. At the time of analysis, 240 of the 253 eligible patients were evaluable for induction. Of these, 11 (5%) died of early complications and 229 (95%) achieved hematologic remission. No cases of resistant leukemia were observed. Of 139 cases studied by RT-PCR after induction, 84 (60.5%) were PCR-negative and 55 (39.5%) PCR-positive. One hundred sixty-two patients were evaluable by RT-PCR at the end of consolidation. Of these, 159 (98%) tested PCR-negative and 3 (2%), PCR-positive. After a median follow up of 12 months (range, 0 to 33), the estimated actuarial event-free survival for the whole series of 253 eligible patients was 83% +/- 2.6% and 79% +/- 3.2% at 1 and 2 years, respectively. This study indicates that the AIDA protocol is a well-tolerated regimen that induces molecular remission in almost all patients with PML/RAR alpha-positive APL. Preliminary survival data suggest that a remarkable cure rate can be obtained with this treatment.

  1. Teologinių klausimų specifika literatūroje: nuodėmės refleksija Aido Marčėno eilėraščiuose | Specifics of theological questions in literature: sin in the texts of Aidas Marčėnas

    Full Text Available The problem of this article arise from the challenges of interdisciplinary study of literature and theology – how to find a scientifically acceptable way of representing theological questions in literature, preserving the autonomy and at the same time highlighting common dialogically-based points of view of these two fields. The theological point of view to literature is based on its interest in the metaphorical, symbolical and image-based language of literature, which can express the deepest existential questions and transcendental dimensions of human essence. Literary theory deals with its autonomy and its connections with other fields of humanities: ethics, politics, and religion. Theological questions in literature might be viewed as individual religious experiences expressed in text and understood as representations of feelings and views that might be understood and perceived as common experience. Theological questions in literature are based on the specifics of the literary language of images and poetic language. Theological questions in literature also arise from its esthetic value and esthetic language. One of the methodological possibilities to deal with challenges of this interdisciplinary field might be to research what theological questions are, and how these questions arise in literature. Sin and guilt in the poetry of Aidas Marčėnas is reflected as individual and subjective theological question very much related with the understanding of human existence and creative nature.

    Full Text Available In order to know the habitat preference gradation for gall-forming insects from the border to the middle of the habitat or more precise the edge effect on the galling existence and the expansion ability of local gall to infect on non indigenous species, observation of all plant life collections block by block in the Bogor Botanic Garden were done. Host plant and galling insect species composition differed quite characteristically between the edge and the interior of paths, but did not for galling insect richness. Insect gall richness was expressed as the ratio between insect gall and host plant richness (gall per plant ratio and in the same time a weak relationship of insect species–area was found. Our results suggest that the number of galling insects per individual plant is not affected by the size of the patch. Despite these results, the natural forest patches are found in this region seem well suited for long-term studies addressing species–area relationships.

In general, design system and the use of signage, such as graphic standard, material and the positioning, has been organized by international standardization from every country in the world. One of the most important categories of signage is the application of signage in highways. The study is about signage from historical background, category, color scheme, design and human factor approach; from psychological physics, social culture, to the connectivity with the value and products characteristic. Human factor comprehension is also one of the most important elements in signage design process. Each perspective or perception from highway user and their reaction about the signage has been conditioned by a specific characteristic of human, such as from biophysics-psyche, socio-culture, spiritual cosmologis transcendental with its five senses. Human factor as a user has an important role to obtain the best solution or good design solution for the community who use that signage.

    Full Text Available Las Crónicas de Indias no se comprenden por entero como la mera respuesta a la pregunta básica "(Que pasó?", lo que asombra poco si recordamos con Roman Jakobson que un mensaje puede cumplir más de una función y, con Roland Barthes o Hayden White, que el lenguaje transparente de la historiografía tiene menos de transparente que de interesado. No es preciso insistir aquí en unas ideas que han sido ya expuestas casi a modo de sentencia: "el novelar y el historiar son equivalencias del tramar, es decir, de decisión poética”. La forma, ya que no del todo el pasado al que se refiere, queda a merced del historiador. Un unico suceso puede ser materia de múltiples relatos. El modo de contar reclama de por sí atención por venir colmado de significado, "excedente" de significado que emana de una construcción elegida y que permanece como un valor del texto, aun cuando el valor histórico se cuestione y se juzgue mínimo.

  10. Single Particle Soot Photometer intercomparison at the AIDA chamber

    2012-12-01

    Full Text Available Soot particles, consisting of black carbon (BC, organic carbon (OC, inorganic salts, and trace elements, are emitted into the atmosphere during incomplete combustion. Accurate measurements of atmospheric BC are important as BC particles cause adverse health effects and impact the climate.

    Unfortunately, the accurate measurement of the properties and mass concentrations of BC particles remains difficult. The Single Particle Soot Photometer (SP2 can contribute to improving this situation by measuring the mass of refractory BC in individual particles as well as its mixing state.

    Here, the results of the first detailed SP2 intercomparison, involving 6 SP2s from 6 different research groups, are presented, including the most evolved data products that can presently be calculated from SP2 measurements.

    It was shown that a detection efficiency of almost 100% down to 1 fg BC per particle can readily be achieved, and that this limit can be pushed down to ∼0.2 fg BC with optimal SP2 setup. Number and mass size distributions of BC cores agreed within ±5% and ±10%, respectively, in between the SP2s, with larger deviations in the range below 1 fg BC.

    The accuracy of the SP2's mass concentration measurement depends on the calibration material chosen. The SP2 has previously been shown to be equally sensitive to fullerene soot and ambient BC from sources where fossil fuel was dominant and less sensitive to fullerene soot than to Aquadag. Fullerene soot was therefore chosen as the standard calibration material by the SP2 user community; however, many data sets rely solely on Aquadag calibration measurements. The difference in SP2 sensitivity was found to be almost equal (fullerene soot to Aquadag response ratio of ∼0.75 at 8.9 fg BC for all SP2s. This allows the calculation of a fullerene soot equivalent calibration curve from a measured Aquadag calibration, when no fullerene soot calibration is available. It could be shown that this approach works well for all SP2s over the mass range of 1–10 fg. This range is suitable for typical BC mass size distributions in the ambient air far from sources.

    The number size distribution of purely scattering particles optically measured by the 6 SP2s also agreed within 15%. Measurements of the thickness of non-refractory coatings (i.e. product from α-pinene ozonolysis on the BC particles, relying on BC mass optical size and on an additional particle position measurement, also compared well (within ±17%. The estimated coating thickness values were consistent with thermo-optical analysis of OC and elemental carbon (EC content, though absolutely accurate values cannot be expected given all the assumptions that have to be made regarding refractive index, particle morphology, etc.

    This study showed that the SP2 provides accurate and reproducible data, but also that high data quality is only achieved if the SP2 is carefully tuned and calibrated. It has to be noted that the agreement observed here does not account for additional variability in output data that could result from the differences in the potentially subjective assumptions made by different SP2 users in the data processing.

    The rising competition in land use especially between water economy, agriculture, forestry, building material economy and other industries often leads to irreversible deterioration in the water and soil system (as salinization and degradation) which results in a long term damage of natural resources. A sustainable exploitation of the near subsurface by industry, economy and private households is a fundamental demand of a modern society. To fulfill this demand, a sound and comprehensive knowledge on structures and processes of the near subsurface is an important prerequisite. A spatial survey of the usable underground by aerogeophysical means and a subsequent ground geophysics survey targeted at special locations will deliver essential contributions within short time that make it possible to gain the needed additional knowledge. The complementary use of airborne and ground geophysics as well as the validation, assimilation and improvement of current findings by geological and hydrogeological investigations and plausibility tests leads to the following key questions: a) Which new and/or improved automatic algorithms (joint inversion, data assimilation and such) are useful to describe the structural setting of the usable subsurface by user specific characteristics as i.e. water volume, layer thicknesses, porosities etc.? b) What are the physical relations of the measured parameters (as electrical conductivities, magnetic susceptibilities, densities, etc.)? c) How can we deduce characteristics or parameters from the observations which describe near subsurface structures as ground water systems, their charge, discharge and recharge, vulnerabilities and other quantities? d) How plausible and realistic are the numerically obtained results in relation to user specific questions and parameters? e) Is it possible to compile material flux balances that describe spatial and time dependent impacts of environmental changes on aquifers and soils by repeated airborne surveys? In order to follow up these questions raised the project aims to achieve the following goals: a) Development of new and expansion of existent inversion strategies to improve structural parameter information on different space and time scales. b) Development, modification, and tests for a multi-parameter inversion (joint inversion). c) Development of new quantitative approaches in data assimilation and plausibility studies. d) Compilation of optimized work flows for fast employment by end users. e) Primary goal is to solve comparable society related problems (as salinization, erosion, contamination, degradation etc.) in regions within Germany and abroad by generalization of project results.

    Full Text Available Plants are an important part of the cycle of life, but often overlooked by human existence. Lots of plants are on the verge of extinction so it is difficult to see their figures. Many efforts have been done by agencies to preserve the rare plant. With the 3-dimensional visualization that replaces the figures of the ungrowing plants, the authors intend to make a 3D prototype application of rare plant encyclopedia. The goal is to simplify the users, especially visitors of Plant Conservation Center Library to see 3-dimensional model of rare plants. The application is created through several stages of research, including field observations and interviews, library research, and related researches. Vaughan multimedia development is implemented for system development which has 4 stages. First is planning by searching target audiences, and making design concept of and navigation concept. Next is design and production phase using 5 activities such as storyboard, flowchart, interface design, content search and production. Alpha and Beta testing is used as the testing phase. The last is the multiplication and distribution phase of application deployment. This application can allow users to search for information about the world of plants. For further development of the process, the application is expected to run in a web-based media to be accessible by public.

    Full Text Available Problems of humans vary considerably. One major problem concerns religion. Under a normal condition, one can observe religious rites properly. Problems arise, however, when one, especially children, lives in a family whose members practice different religions. This can be seen, for example, in many families in Palangkaraya, Central Kalimantan. The decision to follow a particular religion and practice it in a multi religious family is challenging. There is a problem between the conscience to practice the religion in accordance to one’s own faith and the pressure to follow parents or foster parents who practice different religious. This article examines not only how adolescents choose their own religion but also how they practice religious rites in a multi religious families. Using qualitative-fenomenology approach, the data consitsed of ten families and were collected trough partipative observation and depth interview techniques. Findings show that adolescents have serious problems not only as to how they decide their own religion but also how they should observe their religious rituals. They felt confused, doubt, and event affraid of doing religious rites differently in such families. Findings also show that there are correlations between parents’ defferent religion and their low-motivation in religious activities and understanding religion.

    Full Text Available The characteristics and viability of agarwood (Aquilaria microcarpa Baill. seed from the Bogor Botanic Garden's collection was investigated. Two batches of seed from intact mature fruit and dehisced mature fruit were tested for viability using germination and tetrazolium test methods. The result showed that although the tetrazolium test indicated a similar level of seed viability between the two batches (i.e. 85 — 93 %, the germination capacity of seed batch derived from dehisced fru,it was greatly reduced (i.e. 46 % total seed germination compared to that derived from intact fruit (i.e. 97 % total seed germination. The decrease of seed germination capacity indicated the loss of seed vigour and was concomitant with the decrease of seed moisture content from 42.22 % to 24.79 % (fresh weight basis, thus underlining that the seed has a recalcitrant characteristic. Further observation on the seedling growth showed that there was an incidence of abnormal seedlings encountered in the seed batch from dehisced fruit.

    Full Text Available A study on flower biology of Cassine koordersii Kostermans was carried out in the Bogor Botanic Garden on April — November 2002. The plant produces flowers in umbel inflorescences that open sequentially, starting from the lowest branch of the inflorescence. There is no spatial separation between the anther and the stigma, and the dispersal of highly viable pollen takes place within the period of stigma receptivity. The flowers also show some characters of entomophily. Visitor insects are flies (ordo Diptera, family Syrphidae and Tachinidae and ants (ordo Hymenoptera, family Formicidae. In general, the morphological and phenological characteristics of the flower allow self pollination to occur successfully. Floral assessment using Cruden's Outcrossing Index showed that the flower is self-compatible.

    In year 2000 the Danish Parliament decided to fund a four-year particle research programme, which should include characterization of physical and chemical properties of the particles in Denmark and their sources and also assess the adverse health effects and the socio-economic impact in the Danish society. The overall objective of the particle programme is to provide new and broader knowledge in Denmark on the health effect of atmospheric particles with the aim to develop strategies to reduce the adverse health effect of man-made and natural sources. The activities should be closely related to other activities in Denmark and internationally. Specifically National Environmental Research Institute (NERI) shall investigate emissions, size distributions, chemical composition, transformation and dispersion of particles. The present report is the mid-term report on the activities at NERI, and is a summary oef the experimental results, analysis of particle in relation to sources - especially road traffic - and the papers published in connection with the programme.

  1. A preliminary assessment of asteroid shapes produced by impact disruption and re-creation: Application to the AIDA target.

    2016-04-01

    In order to understand the origin of the 65803 Didymos, the target of the Asteroid Impact and Deflection Assessment mission, and gain insights on the origin and evolution of the asteroid's162173 Ryugu and 101955 Bennu, we investigate systematically the shapes of all re-accumulated fragments produced by the catastrophic disruption of a parent body that is 1 km in diameter or larger. These new fragments eventually become new asteroids of the size that current sample-return missions plan to explore. We choose a range of impact conditions by varying the parent bodies' strength, size and porosity, and the velocity and size of the projectile. Impact conditions range from near the catastrophic threshold, usually designated by Q*, where half of the target's mass escapes, to far greater values above this threshold. Our numerical investigations of the catastrophic disruption, which are undertaken using an SPH hydrocode, include a model of fragmentation for porous materials. The gravitationally dominated phase of reaccumulation of our asteroids is computed using the N-body code pkdgrav. At sufficiently slow impact speeds in the N-body model, particles are permitted to stick, forming irregular, competent pieces that can gather into non-idealized rubble piles as a result of re-accumulation. Shape and spin information of re-accumulated bodies are thus preserved. Due to numerical expense, this first study uses what we call a hard-sphere model, rather than a soft-sphere spring and dashpot model. This latter model is more commonly used in granular flow simulations for which detailed treatment of the multicontact physics is needed, which is not the case here, and comes at the expense of much smaller timesteps. With the hard-sphere model, there are three supported collision outcomes for bonded aggregates: sticking on contact (to grow the aggregate); bouncing (computed for these generally non-central impacts); and fragmentation (wherein the particles involved become detached from their respective aggregates and proceed to bounce as rigid spheres, possibly releasing more particles). We adjusted the strength of the forming aggregates to the measured strength of materials in the lab, scaled to the aggregate size, by using strength size scaling rules. In the future we expect to compare our hard-sphere models to a few soft-sphere for reasonable granular materials to best characterize differences between the two approaches, if any. Our results indicate that while 25143 Itokawa-like potato-shaped asteroids are typically the outcome of disruption, often more spherical or "top-shaped" asteroids can also be produced. Our results confirm what others have already noted, namely that a "top-shaped" or diamond shaped asteroid is not necessarily the result of the formation of YORP spin-up. Other criteria besides just shape need to be developed to determine whether or not the evolution of an asteroid and its surface geology have been dominated by YORP-related processes or by impact-derived re-accretion.

    Introduction The emergence of antibiotic-resistant bacteria has driven renewed interest in older antibacterials, including colistin. Previous studies have shown that colistin is less effective and more toxic than modern antibiotics. In vitro synergy studies and clinical observational studies suggest a benefit of combining colistin with a carbapenem. A randomised controlled study is necessary for clarification. Methods and analysis This is a multicentre, investigator-initiated, open-label, randomised controlled superiority 1:1 study comparing colistin monotherapy with colistin–meropenem combination therapy for infections caused by carbapenem-resistant Gram-negative bacteria. The study is being conducted in 6 centres in 3 countries (Italy, Greece and Israel). We include patients with hospital-associated and ventilator-associated pneumonia, bloodstream infections and urosepsis. The primary outcome is treatment success at day 14, defined as survival, haemodynamic stability, stable or improved respiratory status for patients with pneumonia, microbiological cure for patients with bacteraemia and stability or improvement of the Sequential Organ Failure Assessment (SOFA) score. Secondary outcomes include 14-day and 28-day mortality as well as other clinical end points and safety outcomes. A sample size of 360 patients was calculated on the basis of an absolute improvement in clinical success of 15% with combination therapy. Outcomes will be assessed by intention to treat. Serum colistin samples are obtained from all patients to obtain population pharmacokinetic models. Microbiological sampling includes weekly surveillance samples with analysis of resistance mechanisms and synergy. An observational trial is evaluating patients who met eligibility requirements but were not randomised in order to assess generalisability of findings. Ethics and dissemination The study was approved by ethics committees at each centre and informed consent will be obtained for all patients. The trial is being performed under the auspices of an independent data and safety monitoring committee and is included in a broad dissemination strategy regarding revival of old antibiotics. Trial registration number NCT01732250 and 2012-004819-31; Pre-results. PMID:27098822

    In CRISPR-based screens for essential genes, Munoz and colleagues and Aguirre and colleagues show that gene-independent targeting of genomic amplifications in human cancer cell lines reduces proliferation or survival. The correlation between CRISPR target site copy number and lethality demonstrates the need for scrutiny and complementary approaches to rule out off-target effects and false positives in CRISPR screens.

    Full Text Available Dinosaur tracks have been identified near San Martín Atexcal, southern Puebla, Mexico, within the sedimentary sequence of the San Juan Raya Formation of Lower Cretaceous (Albian age. The tracksite, located in the bed of the Magdalena River, reveals six different ichnofossiliferous levels identified within a 9 m thick sedimentary sequence. The inferred environment is that of a tidal (marginal marine mudflat (Level I. Level I preserves three theropods trackways (?Allosauroidea, additionally, isolated tracks belonging to iguanodontids (Ornithopoda. Level II preserves faint iguanodontid tracks. Levels III to V preserve sauropod tracks. Younger level VI preserves, although morphologically different, a track belonging to Ornithopoda. The dinosaur tracks from San Martín Atexcal support the existence of continental facies within the San Juan Raya Formation; they represent the second record of dinosaur tracks from the Lower Cretaceous of Mexico and are part of an important but little documented record of Lower Cretaceous dinosaurs in Mexico.

The types of accidents which could result in such a spill are described, and the role of expert systems in managing such an accident is explained. The stages of conceptual analysis and computer implementation of the AIDA expert system are then reviewed. To date, the AIDA system includes more than 600 rules and procedures which refer to over 450 variables or different facts. The architecture of the system is composed of four distinct rule bases, each associated with one of four stages of problem resolution (determination of the possible flow paths of pollutant if no action is taken, visual reconnaissance, selection and prioritization of locations where intervention should occur, and determination of the means of intervention appropriate for each location). Uniform procedures for reading of data and output of results allow each rule base to operate independently and only to recover the information that each requires. The AIDA man-machine interface is designed to allow the user to visualize the propagation of the pollutant in the environment, the management of the spill, and the necessary or useful information for understanding the reasoning behind the recommendations proposed by the expert system. 7 refs., 3 figs

    The present study established a rat cortical neuronal model of in vitro mechanical injury. At 30 min-utes after injury, the survival rate of the injured cortical neurons was decreased compared with normal neurons, and was gradually decreased with aggravated degree of injury. Reverse transcrip-tion-polymerase chain reaction results showed that at 1 hour after injury, there was increased ex-pression of metabotropic glutamate receptor 1a in cortical neurons. Immunohistochemical staining results showed that at 30 minutes after injury, the number of metabotropic glutamate receptor 1a-positive cells increased compared with normal neurons. At 12 hours after injury, lactate dehy-drogenase activity in the (RS)-1-aminoindan-1, 5-dicarboxylic acid (AIDA)-treated injury neurons was significantly decreased than that in the pure injury group. At 1 hour after injury, intracellular free Ca2+ concentration was markedly decreased in the AIDA-treated injury neurons than that in the pure injury neurons. These findings suggest that after mechanical injury to cortical neurons, metabotropic glutamate receptor 1a expression increased. The resulting increase in intracellular free Ca2+ con-centration was blocked by AIDA, indicating that AIDA exhibits neuroprotective effects after me-chanical injury.

  5. Ice Nucleation Activity of Various Agricultural Soil Dust Aerosol Particles

    Recent investigations at the cloud simulation chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere) suggest that agricultural soil dust has an ice nucleation ability that is enhanced up to a factor of 10 compared to desert dust, especially at temperatures above -26 °C (Steinke et al., in preparation for submission). This enhancement might be caused by the contribution of very ice-active biological particles. In addition, soil dust aerosol particles often contain a considerably higher amount of organic matter compared to desert dust particles. To test agricultural soil dust as a source of ice nucleating particles, especially for ice formation in warm clouds, we conducted a series of laboratory measurements with different soil dust samples to extend the existing AIDA dataset. The AIDA has a volume of 84 m3 and operates under atmospherically relevant conditions over wide ranges of temperature, pressure and humidity. By controlled adiabatic expansions, the ascent of an air parcel in the troposphere can be simulated. As a supplement to the AIDA facility, we use the INKA (Ice Nucleation Instrument of the KArlsruhe Institute of Technology) continuous flow diffusion chamber based on the design by Rogers (1988) to expose the sampled aerosol particles to a continuously increasing saturation ratio by keeping the aerosol temperature constant. For our experiments, soil dust was dry dispersed into the AIDA vessel. First, fast saturation ratio scans at different temperatures were performed with INKA, sampling soil dust aerosol particles directly from the AIDA vessel. Then, we conducted the AIDA expansion experiment starting at a preset temperature. The combination of these two different methods provides a robust data set on the temperature-dependent ice activity of various agriculture soil dust aerosol particles with a special focus on relatively high temperatures. In addition, to extend the data set, we investigated the role of biological and organic matter in more

  6. Use of CFD modeling for estimating spatial representativeness of urban air pollution monitoring sites and suitability of their locations

    International Nuclear Information System (INIS)

    A methodology to estimate the spatial representativeness of air pollution monitoring sites is applied to two urban districts. This methodology is based on high resolution maps of air pollution computed by using Computational Fluid Dynamics (CFD) modelling tools. Traffic-emitted NO2 dispersion is simulated for several meteorological conditions taking into account the effect of the buildings on air flow and pollutant dispersion and using a steady state CFD-RANS approach. From these results, maps of average pollutant concentrations for January -May 2011 are computed as a combination of the simulated scenarios. Two urban districts of Madrid City were simulated. Spatial representativeness areas for 32 different sites within the same district (including the site of the operative air quality stations) have been estimated by computing the portion of the domains with average NO2 concentration differing less than a 20% of the concentration at each candidate monitoring site. New parameters such as the ratio AR between the representativeness area and the whole domain area or the representativeness index (IR) has been proposed to discuss and compare the representativeness areas. Significant differences between the spatial representativeness of the candidate sites of both studied districts have been found. The sites of the Escuelas Aguirre district have generally smaller representativeness areas than those of the Plaza de Castilla. More stations are needed to cover the Escuelas Aguirre district than for the Plaza de Castilla one. The operative air quality station of the Escuelas Aguirre district is less representative than the station of the Plaza de Castilla district. The cause of these differences seems to be the differences in urban structure of both districts prompting different ventilation. (Author)

    2016-08-01

    The eruption of the Chaitén volcano in May 2008 generated morphological and ecological disturbances in adjacent river basins, and the magnitude of these disturbances depended on the type of dominant volcanic process affecting each of them. The aim of this study is to analyse the morphological changes in different periods in river segments of the Blanco, El Amarillo and Rayas river basins located near the Chaitén volcano. These basins suffered disturbances of different intensity and spatial distribution caused by tephra fall, dome collapses and pyroclastic density currents that damaged hillslope forests, widened channels and destroyed island and floodplain vegetation. Changes continued to occur in the fluvial systems in the years following the eruption, as a consequence of the geomorphic processes indirectly induced by the eruption. Channel changes were analyzed by comparing remote images of pre and post-eruption conditions. Two periods were considered: the first from 2008 to 2009-2010 associated with the explosive and effusive phases of the eruption and the second that correspond to the post-eruption stage from 2009-2010 to 2013. Following the first phases channel segments widened 91% (38 m/yr), 6% (7 m/yr) and 7% (22 m/yr) for Blanco, Rayas and El Amarillo Rivers, respectively, compared to pre-eruption condition. In the second period, channel segments additionally widened 42% (8 m/yr), 2% (2 m/yr) and 5% (4 m/yr) for Blanco, Rayas and El Amarillo Rivers, respectively. In the Blanco River 62 and 82% of the islands disappeared in the first and second period, respectively, which is 6-8 times higher than in the El Amarillo approximately twice the Rayas. Sinuosity increased after the eruption only in the Blanco River but the three study channels showed a high braiding intensity mainly during the first post-eruption period. The major disturbances occurred during the eruptive and effusive phases of Chaitén volcano, and the intensity of these disturbances reflects the

    Full Text Available One of the many areas of activity of Cardinal Isidro Goma during the Civil War was the attention to the Basque question. After, the controversy with lehendakari Aguirre A, the result of the alignment of Basque nationalism with the Republic. The primate was also a central role regarding the end of conflict in the Basque Country, with negotiations for the surrender of Bilbao. Finally had to face conflict with the national clergy, who remained in Spain, who was victimized who was exiled or those who criticized the position of Cardinal Goma.Uno de los múltiples campos de actuación del cardenal Isidro Gomá durante la guerra civil fue la atención a la cuestión vasca. En primer lugar los problemas derivados del enfrentamiento de las autoridades militares con el obispo de Vitoria, Mateo Múgica. Después la polémica entre el propio Gomá y el lehendakari Aguirre, consecuencia del alineamiento del nacionalismo vasco con la República.

    Two new species of Anagyrus Howard (Hymenoptera: Encyrtidae) are described from Argentina, A. cachamai Triapitsyn, Logarzo & Aguirre sp. n. (Catamarca, Córdoba, Salta and Tucumán Provinces) and A. quilmes Triapitsyn, Logarzo & Aguirre sp. n. (Catamarca, Salta and Tucumán). Both new species are parasitoids of Hypogeococcus spp. (Hemiptera: Pseudococcidae). Anagyrus cachamai is a parasitoid of H. pungens Granara de Willink on Alternanthera paronychioides, A. pungens and Gomphrena sp. (Amaranthaceae), and also of a Hypogeococcus sp. on Cleistocactus baumannii and Hypogeococcus sp. on C. smaragdiflorus (Cactaceae). Anagyrus quilmes is a parasitoid of H. pungens on A. paronychioides, A. pungens and Gomphrena sp. Other biological traits of the new species are also reported. These parasitoids may be of importance as potential candidate biological control agents against a Hypogeococcus sp., commonly called the Harrisia cactus mealybug and identified as H. pungens, but possibly not belonging to that species. This mealybug threatens the native cacti in some Caribbean islands and Florida, USA, and is devastating the native columnar cacti in Puerto Rico. Illustrations and taxonomic notes on the type specimens of some other, little known described species of Anagyrus from Argentina and Chile are provided, and a key to females of the 14 species of Anagyrus known from Argentina is given. Anagyrus nigriceps (De Santis) syn. n. is synonymized under A. bellator (De Santis). Lectotypes are designated for Paranusia bifasciata Brèthes, Philoponectroma pectinatum Brèthes, and Protanagyrus aciculatus Blanchard.

    Full Text Available In this paper we describe the fossils of macromarnmals provided by Las Majolicas site (Granada, Spain. This site was excavated in the 50's by E. Aguirre. The high frecuency of cervids with 469 fossils identified out of 558 is remarkable. We have compared Cervus elaphus from Las Majolicas with others that belong to the Cantabrian Range and we can conclude that they have smaller sizes, a fact which can be related to the more meridional situation of the site. According to the fauna that appears in Las Majolicas this site might be located in the Upper Pleistocene.En este trabajo se describen los fósiles de macromamíferos del yacimiento de Las Majolicas (Granada, España, excavado en la década de los cincuenta por E.

Los restos de Cervus elaphus al compararlos con otros ejemplares del Pleistoceno superior de la Cordillera Cantábrica presentan un menor tamaño, lo cual podría indicar una reducción de la talla en relación al nivel más meridional de esta localidad. La fauna presente en Las Majolicas indica su posible asignación al Pleistoceno Superior

  14. Using GAIDA (Guide to AI Data Analysis) to analyze data collected from artificial insemination programmes for cattle in developing countries

    International Nuclear Information System (INIS)

    The objectives of AIDA (Artificial Insemination Database Application) and its companion GAIDA (Guide to AI Data Analysis) are to address two major problems in on-farm research on livestock production. The first is the quality of the data collected and the second is the intellectual rigor of the analyses and their associated results when statistically testing causal hypotheses. The solution is to develop a data management system such as AIDA and an analysis system such as GAIDA to estimate parameters that explain biological mechanisms for on-farm application. The system uses epidemiological study designs in the uncontrolled research environment of the farm, uses a database manager (Microsoft Access) to handle data management issues encountered in preparing data for analysis, and then uses a statistical program (SYSTAT) to do preliminary analyses. These analyses enable the researcher to have better understanding of the biological mechanisms involved in the data contained within the AIDA database. Using GAIDA as a guide, this preliminary analysis helps to determine the strategy for further in-depth analyses. (author)

    An understanding of the post-impact dynamics of ejecta clouds are crucial to the planning of a kinetic impact mission to an asteroid, and also has great implications for the history of planetary formation. The purpose of this article to track the evolution of ejecta produced by AIDA mission, which targets for kinetic impact the secondary of near-Earth binary asteroid 65803 Didymos on 2022, and to feedback essential informations to AIDA's ongoing phase-A study. We present a detailed dynamic model for the simulation of an ejecta cloud from a binary asteroid that synthesizes all relevant forces based on a previous analysis of the mechanical environment. We apply our method to gain insight into the expected response of Didymos to the AIDA impact, including the subsequent evolution of debris and dust. The crater scaling relations from laboratory experiments are employed to approximate the distributions of ejecta mass and launching speed. The size composition of fragments is modeled with a power law fitted from obs...

    2016-04-01

    ESA's Asteroid Impact Mission (AIM) is being studied as part of the joint ESA/NASA AIDA mission for launch in 2020. AIDA's primary mission is to investigate the effect of a kinetic impactor on the secondary component of the binary asteroid 65803 Didymos in late 2022. AIM will characterise the Didymos system and monitor the response of the binary system to the impact. A multi-spectral, thermal-infrared imaging instrument (TIRI) will be an essential component of AIM's remote sensing payload, as it will provide key information on the nature of the surfaces (e.g. presence or absence of materials, degree of compaction, and rock abundance of the regolith) of both components in the Didymos system. The temperature maps provided by TIRI will be important for navigation and spacecraft health and safety for proximity/lander operations. By measuring the asteroids' diurnal thermal responses (thermal inertia) and their surface compositions via spectral signatures, TIRI will provide information on the origin and evolution of the binary system. In this presentation we will discuss possible instrument design for TIRI, exploring options that include imaging spectroscopy to broadband imaging. By using thermal models and compositional analogues of the Didymos system we will show how the performance of each design option compares to the wider scientific goals of the AIDA/AIM mission.

    Terminal residues of pendimethalin and oxyfluorfen applied in autumn sugarcane- and vegetables-based intercropping systems were analyzed in peas (Pisum sativum), cabbage (Brassica oleracea), garlic (Allium sativum), gobhi sarson (Brassica napus), and raya (Brassica juncea). The study was conducted in winter season in 2010-2011 and in 2011-2012 at Ludhiana, India. Pendimethalin at 0.56 kg and 0.75 kg ha(-1) was applied immediately after sowing of gobhi sarson, raya, peas, garlic, and 2 days before transplanting of cabbage seedlings. Oxyfluorfen at 0.17 kg and 0.23 kg ha(-1) was applied immediately after sowing of peas and garlic and 2 days before transplanting of cabbage seedlings intercropped in autumn sugarcane. Representative samples of these vegetables were collected at 75, 90, 100, and 165 days after application of herbicides and analyzed by high-performance liquid chromatograph (HPLC) with diode array detector for residues. The residue level of pendimethalin and oxyfluorfen in mature vegetables was found to be below the limit of quantification which is 0.05 mg kg(-1) for both the herbicides. The soil samples were collected at 0, 7, 15, 30, 45, and 60 days after the application of their herbicides. The residues of herbicides in soil samples were found to be below the detectability limit of 0.05 mg kg(-1) after 60 days in case of pendimethalin and after 45 days in case of oxyfluorfen.

For each species we recorded its behavior when first encountering tourists and its reaction following this encounter. A Correspondence Analysis revealed that the type of reaction of the species depended significantly on the type of touristic activity, with the exception of the black spotted and eagle rays. Moreover, the analysis showed that, for each species, the different tourist activities were significantly associated with particular animal activities

    A longitudinal depression, the Central Valley, separates the Coast Range from the Andean Cordillera in central Chile. It contains volcanic and volcaniclastic rocks of Late Cretaceous to Tertiary age deposited in a continental environment, and partly eroded Tertiary volcanic complexes. The age of the rocks at the northern end of the Central Valley and their grouping in formations have been a long-standing controversy in Chilean geology (Thomas, 1958; Aguirre, 1960; Drake et al., 1976; Vergara and Drake, 1979; Thiele, 1980; Moscoso et al., 1982; Gana and Wall, 1997; Lopez-Escobar and Vergara, 1997; Selles, 1999).

  15. Finding Distances to Type Ia Supernovae

    Type Ia supernovae are known as standard candles due to their consistency, allowing us to measure distances based on their brightness. But what if these explosions arent quite as consistent as we thought? Due scientific diligence requires careful checks, so a recent study investigates whether the metallicity of a supernovas environment affects the peak luminosity of the explosion.Metallicity Dependence?Type Ia supernovae are incredibly powerful tools for determining distances in our universe. Because these supernovae are formed by white dwarfs that explode when they reach a uniform accreted mass, the supernova peak luminosity is thought to be very consistent. This consistency allows these supernovae to be used as standard candles to measure distances to their host galaxies.But what if that peak luminosity is affected by a factor that we havent taken into account? Theorists have proposed that the luminosities of Type Ia supernovae might depend on the metallicity of their environments with high-metallicity environments suppressing supernova luminosities. If this is true, then we could be systematically mis-measuring cosmological distances using these supernovae.Testing AbundancesSupernova brightnesses vs. the metallicity of their environments. Low-metallicity supernovae (blue shading) and high-metallicity supernovae (red shading) have an average magnitude difference of ~0.14. [Adapted from Moreno-Raya et al. 2016]A team led by Manuel Moreno-Raya, of the Center for Energy, Environment and Technology (CIEMAT) in Spain, has observed 28 Type Ia supernovae in an effort to test for such a metallicity dependence. These supernovae each have independent distance measurements (e.g., from Cepheids or the Tully-Fisher relation).Moreno-Raya and collaborators used spectra from the 4.2-m William Herschel Telescope to estimate oxygen abundances in the region where each of these supernovae exploded. They then used these measurements to determine if metallicity of the local region

    The development of ultra-light pixelated ladders is motivated by the requirements of the ILD vertex detector at ILC. This paper summarizes three projects related to system integration. The PLUME project tackles the issue of assembling double-sided ladders. The SERWIETE project deals with a more innovative concept and consists in making single-sided unsupported ladders embedded in an extra thin plastic enveloppe.

    The PLUME (Pixelated Ladder with Ultra-Low Material Embedding) Collaboration is developing ultra-light ladders for the vertex detector for a future linear collider. The double-sided ladder will integrate the sensors, readout infrastructure and mechanical supports with the aim of total material budget of 0.3% of radiation length. The requirement of as light as possible construction is driven by physics, in particular by measurements requiring determination of the quark charge sign. The first prototype ladders were prepared and tested in the beam. The alignment issues for the ladders will be tested within the AIDA (Advanced European Infrastructures for Detectors at Accelerators) EU FP7 project.

    The Asteroid Impact Mission (AIM) is a small and innovative mission of opportunity, currently under study at ESA, intending to demonstrate new technologies for future deep-space missions while addressing planetary defense objectives and performing for the first time detailed investigations of a binary asteroid system. It leverages on a unique opportunity provided by asteroid 65803 Didymos, set for an Earth close-encounter in October 2022, to achieve a fast mission return in only two years after launch in October/November 2020. AIM is also ESA's contribution to an international cooperation between ESA and NASA called Asteroid Impact Deflection Assessment (AIDA), consisting of two mission elements: the NASA Double Asteroid Redirection Test (DART) mission and the AIM rendezvous spacecraft. The primary goals of AIDA are to test our ability to perform a spacecraft impact on a near-Earth asteroid and to measure and characterize the deflection caused by the impact. The two mission components of AIDA, DART and AIM, are each independently valuable but when combined they provide a greatly increased scientific return. The DART hypervelocity impact on the secondary asteroid will alter the binary orbit period, which will also be measured by means of lightcurves observations from Earth-based telescopes. AIM instead will perform before and after detailed characterization shedding light on the dependence of the momentum transfer on the asteroid's bulk density, porosity, surface and internal properties. AIM will gather data describing the fragmentation and restructuring processes as well as the ejection of material, and relate them to parameters that can only be available from ground-based observations. Collisional events are of great importance in the formation and evolution of planetary systems, own Solar System and planetary rings. The AIDA scenario will provide a unique opportunity to observe a collision event directly in space, and simultaneously from ground-based optical and

    The role of aerosol particles for ice formation in clouds is one of the largest uncertainties in understanding the Earth's weather and climate systems, which is related to the poor knowledge of ice nucleation microphysics or of the nature and atmospheric abundance of ice nucleating particles (INPs). During the recent years, new mobile instruments were developed for measuring the concentration, size and chemical composition of INPs, which were tested during the three-part Fifth International Ice Nucleation (FIN) workshop. The FIN activities addressed not only instrument issues, but also important science topics like the nature of atmospheric INP and cloud ice residuals, the ice nucleation activity of relevant atmospheric aerosols, or the parameterization of ice formation in atmospheric weather and climate models. The first activity FIN-1 was conducted during November 2014 at the AIDA cloud chamber. It involved co-locating nine single particle mass spectrometers to evaluate how well they resolve the INP and ice residual composition and how spectra from different instruments compare for relevant atmospheric aerosols. We conducted about 90 experiments with mineral, carbonaceous and biological aerosol types, some also coated with organic and inorganic compounds. The second activity FIN-2 was conducted during March 2015 at the AIDA facility. A total of nine mobile INP instruments directly sampled from the AIDA aerosol chambers. Wet suspension and filter samples were also taken for offline INP processing. A refereed blind intercomparison was conducted during two days of the FIN-2 activity. The third activity FIN-3 will take place at the Desert Research Institute's Storm Peak Laboratory (SPL) in order to test the instruments' performance in the field. This contribution will introduce the FIN activities, summarize first results from the formal part of FIN-2, and discuss selected results, mainly from FIN-1 for the effect of coating on the ice nucleation (IN) by mineral

    In an effort to increase the value of fish produced by the community in Krueng Raya Sub-district, it has been designed and tested a fish drier system utilizing geothermal energy resource in IeSuum Village, Krueng Raya Sub-district, Aceh Besar District. The geothermal energy is in the form of hot water with the temperature range is between 86 and 86.4 °C. Based on the design consideration, it is used a terraced rack type drier system. The drier system consists of a heat exchanger, drying chamber, and a blower to blow the air. Hot water from the geothermal source is passed into the heat exchanger to increase the air temperature outside it. The air is then blown into the drying chamber. Based on the design analysis is obtained that to dry 200 kg of fish in 24 hour, it is required a drying chamber with 1m long, 1 m width and 0.4 m high, the temperature of hot water entering the exchanger is 80 °C and the temperature of the air entering the drying chamber is maintained at 60°C. The average time required to dry fish till 10% of water level is 18-20 jam. The research is then continued by developing and testing the drying system with three layer rack to put in the fish. From the experimental result is obtained that the average water temperature flows out of the chamber is in the range of 76-78 °C and the temperature in the chamber is in the range of 57-62 °C. In addition, the weight of the fish, which initially is 20 kg, becomes12 kg in average after 18 hours drying process.

  18. Growth and ions (Na/sup +/, K/sup +/ and Cl/sup-1/-) accumulating pattern of some brassica genotypes under saline - sodic field condition

    International Nuclear Information System (INIS)

    The growth and ionic uptake pattern of some Brassica genotypes i.e., Rainbow, Wester, Durr-e-NIFA, Abaseen 95 (Brassica napus) and NIFA raya (Brassica juncea) under saline-sodic field conditions was studied. Two sets of experiments on normal and saline-sodic site were conducted at NIA experimental farm, Tandojam, Pakistan during Rabi 2006-07. The salinity of the experimental site ranged between 11.0-22.9 dS/m and the pH was alkaline (8-8.6). The dominant cation was sodium (Na). The growth performance was recorded at the time of crop harvest in terms of plant height, grain weight / plant, grain yield and 100 grain weight. It was observed that the performance of Wester was better followed by NIFA- raya. The ionic uptake pattern, of leaves, stem and roots showed that the accumulation of Na was less in leaf as compared to stem and roots. However, the genotypes having better performance we re found to have accumulating type of behavior showing comparatively higher Na contents in all plant parts than other genotypes. This suggests that these genotypes might adjust their osmotic potential through the accumulation of sodium in vacuole. On the other hand trend in case of K accumulation was reverse i.e. high in leaves and stem as compared to roots. Higher accumulating pattern of K in leaves might be helpful for reducing the toxic effects of sodium. However, no correlation was observed between K-Na selectivity or K/Na ratio among the genotypes tested. It is therefore concluded that better selective mechanism for Na uptake and strict control of intercellular Na influx for cellular osmotic adjustment could be selected for saline environment.

  19. Selection of elite genotypes for yield and associated traits in f/sub 2:3/ families of interspecific crosses in brassica species

    International Nuclear Information System (INIS)

    Interspecific crosses of Brassica species were evaluated to identify desirable genotypes for yield and associated traits. Parent al species included Brassica napus (Dunkled, Maluko, line A-20-20), B. campestris (lines 1203 and 2163), B. carinata (Peela raya), and B. juncea (lines PR-64 and 89111-1). All traits were segregated in F/sub 2/ population. All parameters were decreased in F/sub 3/ in comparison to F/sub 2/ population, indicating higher response of the crosses to inbreeding depression (0-85%). A reduction in height (12-27%), primary branches (18-35%), pods main raceme-1 (19-35%), seed pod-1 (10-31%), pod length (14-28%), 100-seed weight (5-28%) and seed yield plant/sup -1/ (14-35%) of F3 population was recorded as compared to F2. Heritability estimates were low to medium (50-70%) for primary branches, medium to high (70-80%) for plant height, pod length, seeds pod/sup -1/, and seed yield plant/sup -1/ while low-medium-high for pods raceme-1 and 100-seed weight. It was concluded that selection for one of these characters would be beneficial for the others also. F3 population of Maluko 1203 produced the maximum silique main raceme/sup -1/, seeds silique/sup -1/, silique length and 100-seed weight. Peela raya PR-64 produced the maximum primary branches plant/sup -1/, while 2163 89111-1 was the best for seed yield plant/sup -1/ and plant height in F/sub 3/ as compared to the F/sub 2/ population.

    The catchments in the western Rift Valley escarpment of Northern Ethiopia are highly responsive in terms of hydro-geomorphic changes. With rapid deforestation in the first half of the 20th century, dense gully and scar networks developed, exporting huge amounts of runoff and sediment down to the fertile and densely populated Raya Valley. Consequently, threatening the environment and the livelihoods of the people both in the upstream and downstream areas. To reverse this problem, catchment-scale rehabilitation activities were initiated in the mid-1980s. In this study, we examine the hydro-geomorphic response of streams after catchment rehabilitation. Scar density was digitized from Google Earth imagery (2005) in 20 adjacent catchments and was explained in terms of its corresponding Normalized Difference Vegetation Index (NDVI) and slope gradient. This was accompanied by analysis of incidental repeat photographs and field observations. As evidenced by the series of repeat photographs, the vegetation cover of the catchments decreased up to 1975 and rapid reforestation occurred thereafter. A multiple regression analysis (R2=0.53, Pscar density is negatively correlated with NDVI and positively with average gradient of very steep slopes (>60%). Moreover, due to reduction in discharge and sediment flow from the rehabilitated catchments, stream adjustments were observed in the field: previously braided stream channels have changed to single-thread streams, many lateral bars are stabilized and covered by vegetation, stream channels are incising due to clear water effect and the size of boulder deposits decreases. Therefore, the study shows that, land degradation activities in the upper catchments resulted in changes in hydro-geomorphic characteristics of the streams and reduction in runoff and sediment transport to the Raya Valley. Key words: scar density; NDVI; stream incision; soil and water conservation; stream adjustment; land use change.

    Full Text Available In July and August 1972, I spent five weeks on an expedition to study rattans and other palms in the provinces of Jambi and West Sumatra. This central area of Sumatra was chosen because expeditions have already been made to South Sumatra in February 1971 and March 1972 and to North Sumatra and Aceh with the Kyoto University Expedition in August 1971, and therefore collections made in this central area would link up collections from the south and north and would hence add considerably to our knowledge of the palm flora of this rich island. After advice from the Department of Nature Conservation in Jambi and from Dr. M. Jacobs in Rijksherbarium (Leiden had been considered, it was decided to work westwards from Berbak Nature Reserve on the east coast near Nipah Panjang, to the Bukit Barisan, the main range of Sumatra, to Gunung Kerinci Nature Reserve and G. Tujuh near Sungai Penuh and from there, across the western part of the Bukit Barisan to Padang and Bukittinggi. From Bukittinggi it was planned to visit the Kafflesia arnoldii Nature Reserve at Batang Palupuh, and then return to Jambi by way of Muara Tebo and Muara Tembesi, where reputedly there still exists lowland forest. By more or less confining our collecting activities to the normally neglected Palmae it was hoped that within the time available a large area could be covered reasonably, and a palm transect for central Sumatra made. Two assistants from Bogor accompanied me to help in the difficult task of collecting rattans: Dedy Darnaedi (Herbarium Bogoriense and Abdul Hanan (Kebun Raya. These assistants were also given individual collecting assignments as part of a scheme for training assistants in field botany. Dedy was to collect Pteridophyta and Hanan to collect material for growing in the Kebun Raya. Soetrisno Soewoko, head of Nature Conservation in Jambi accompanied us throughout tha expedition.

    The number and shape of ice crystals present in mixed-phase and ice clouds influence the radiation properties, precipitation occurrence and lifetime of these clouds. Since clouds play a major role in the climate system, influencing the energy budget by scattering sunlight and absorbing heat radiation from the earth, it is necessary to investigate the optical and microphysical properties of cloud particles particularly in situ. The relationship between the microphysics and the single scattering properties of cloud particles is usually obtained by modelling the optical scattering properties from in situ measurements of ice crystal size distributions. The measured size distribution and the assumed particle shape might be erroneous in case of non-spherical ice particles. There is a demand to obtain both information correspondently and simultaneously for individual cloud particles in their natural environment. For evaluating the average scattering phase function as a function of ice particle habit and crystal complexity, in situ measurements are required. To this end we have developed a novel airborne optical sensor (PHIPS-HALO) to measure the optical properties and the corresponding microphysical parameters of individual cloud particles simultaneously. PHIPS-HALO has been tested in the AIDA cloud simulation chamber and deployed in mountain stations as well as research aircraft (HALO and Polar 6). It is a successive version of the laboratory prototype instrument PHIPS-AIDA. In this paper we present the detailed design of PHIPS-HALO, including the detection mechanism, optical design, mechanical construction and aerodynamic characterization.

  5. Allosteric indicator displacement enzyme assay for a cyanogenic glycoside.

    2013-10-18

    Indicator displacement assays (IDAs) represent an elegant approach in supramolecular analytical chemistry. Herein, we report a chemical biosensor for the selective detection of the cyanogenic glycoside amygdalin in aqueous solution. The hybrid sensor consists of the enzyme β-glucosidase and a boronic acid appended viologen together with a fluorescent reporter dye. β-Glucosidase degrades the cyanogenic glycoside amygdalin into hydrogen cyanide, glucose, and benzaldehyde. Only the released cyanide binds at the allosteric site of the receptor (boronic acid) thereby inducing changes in the affinity of a formerly bound fluorescent indicator dye at the other side of the receptor. Thus, the sensing probe performs as allosteric indicator displacement assay (AIDA) for cyanide in water. Interference studies with inorganic anions and glucose revealed that cyanide is solely responsible for the change in the fluorescent signal. DFT calculations on a model compound revealed a 1:1 binding ratio of the boronic acid and cyanide ion. The fluorescent enzyme assay for β-glucosidase uses amygdalin as natural substrate and allows measuring Michaelis-Menten kinetics in microtiter plates. The allosteric indicator displacement assay (AIDA) probe can also be used to detect cyanide traces in commercial amygdalin samples. PMID:24123550

    Scattering properties of mineral dust and ice crystals were investigated in two aerosol chambers (AIDA, ASA) at the Institut fuer Meteorologie und Klimaforschung at Forschungszentrum Karlsruhe. For this purpose, a linear polarised laser (wavelength 488 nm) was directed horizontally though the chamber. The light scattered by the aerosol was detected with photomultipliers in the forward (4 ) and in the backward (176 ) directions whereas the detection in the backward direction was realised polarisation resolved. The expected values for the depolarisation and the forward scattering ratio were computed with the help of T-matrix calculations for spheroids with different sizes and aspect ratios. The scattering properties of several samples of mineral dust (typical size: 0.5 {mu}m) were investigated at room temperature in the ASA chamber. Because of the rotatable laser polarisation, some elements of the scattering matrix were determined, additionally. Ice crystals with sizes between 0.8 {mu}m and 70 {mu}m were generated in the AIDA chamber by the adiabatic cooling technique with heterogeneous nucleation on mineral dust. Size and habit of the ice crystals were investigated with a Cloud Particle Imager. Both a size dependency and a habit dependency and demonstrated by the experiments. The results were compared with the predictions of a model based on geometric optics. (orig.)

    2014-05-01

    Full Text Available Interoperability in health information systems is increasingly a requirement rather than an option. Standards and technologies, such as multi-agent systems, have proven to be powerful tools in interoperability issues. In the last few years, the authors have worked on developing the Agency for Integration, Diffusion and Archive of Medical Information (AIDA, which is an intelligent, agent-based platform to ensure interoperability in healthcare units. It is increasingly important to ensure the high availability and reliability of systems. The functions provided by the systems that treat interoperability cannot fail. This paper shows the importance of monitoring and controlling intelligent agents as a tool to anticipate problems in health information systems. The interaction between humans and agents through an interface that allows the user to create new agents easily and to monitor their activities in real time is also an important feature, as health systems evolve by adopting more features and solving new problems. A module was installed in Centro Hospitalar do Porto, increasing the functionality and the overall usability of AIDA.

  10. A dual tag system for facilitated detection of surface expressed proteins in Escherichia coli

    2012-09-01

    Full Text Available Abstract Background The discovery of the autotransporter family has provided a mechanism for surface expression of proteins in laboratory strains of Escherichia coli. We have previously reported the use of the AIDA-I autotransport system to express the Salmonella enterica serovar Enteritidis proteins SefA and H:gm. The SefA protein was successfully exposed to the medium, but the orientation of H:gm in the outer membrane could not be determined due to proteolytic cleavage of the N-terminal detection-tag. The goal of the present work was therefore to construct a vector containing elements that facilitates analysis of surface expression, especially for proteins that are sensitive to proteolysis or otherwise difficult to express. Results The surface expression system pAIDA1 was created with two detection tags flanking the passenger protein. Successful expression of SefA and H:gm on the surface of E. coli was confirmed with fluorescently labeled antibodies specific for the N-terminal His6-tag and the C-terminal Myc-tag. While both tags were detected during SefA expression, only the Myc-tag could be detected for H:gm. The negative signal indicates a proteolytic cleavage of this protein that removes the His6-tag facing the medium. Conclusions Expression levels from pAIDA1 were comparable to or higher than those achieved with the formerly used vector. The presence of the Myc- but not of the His6-tag on the cell surface during H:gm expression allowed us to confirm the hypothesis that this fusion protein was present on the surface and oriented towards the cell exterior. Western blot analysis revealed degradation products of the same molecular weight for SefA and H:gm. The size of these fragments suggests that both fusion proteins have been cleaved at a specific site close to the C-terminal end of the passenger. This proteolysis was concluded to take place either in the outer membrane or in the periplasm. Since H:gm was cleaved to a much greater extent

    The Chaiten eruption affected all components of old-growth temperate evergreen forest -- trees, canopy epiphytes, vines, and understory - over ~ 400 km2. Vegetation responses differed depending on initial vegetation type, phenologic stage of the vegetation, landscape position, and the character and chronology of geophysical processes. Four distinct phases of the eruption and associated disturbances affected vegetation greenness in satellite imagery: (1) the initial eruption in early May 2008 produced a lateral blast-like pyroclastic density current (PDC) to N and NE and deposited tephra to NE, E, and SE, (2) >650 mm of precipitation May 13-20 caused flooding and redistributed deposits from hillslopes into channels and downstream, (3) collapse of dome in February 2009 caused PDC into Rio Chaiten to S, (4) floods in 2009 (second winter after eruption) rearranged deposits and wood in channels, and exhumed areas buried in earlier phases of the eruption. Vegetation effects included (a) ash deposition on foliage, (b) foliage/branch removal, (c) tree blowdown and scorching of foliage, and (d) burial, removal, and redeposition of wood and sediment. Three trajectories of vegetation change are apparent in satellite imagery: (1) loss of greenness from Dec 2007 to Dec 2008, followed by recovery of greenness in second growing season (Dec 2008-Apr 2009). Field observations indicated (a) tephra washed off trees whose underlying canopies were still intact (thin deposition zone W of volcano), (b) regeneration/sprouting of vegetation whose leaves had been removed or killed (Rio Rayas bridge), (c) regeneration/sprouting of vegetation exhumed by removal of overlying deposits such as in some river channels (Rio Amarillo), or (d) sprouting of understory (Rio Michinmahuida). (2) Initial loss of greenness that persisted through first two growing seasons. Field observations indicated that (a) trees were blown down and little sprouting has occurred (N flank), (b) vegetation was buried in

  13. Use of nuclear techniques for evaluation of first service conception rate in dairy herds with artificial insemination in Chile

    International Nuclear Information System (INIS)

    The objective of this study was to identify causes of inefficiency in Artificial Insemination (AI) services in 12 dairy farms located in southern Chile. Milk progesterone concentration was determined on the day of breeding and then 10-12 and 21-22 days after AI. Data for semen and cow inseminated, including physical signs of oestrus, were recorded in a computer database (AIDA). Information from 713 cows with first services was analysed. The mean interval from calving to first service was 88.7 days and the mean interval from calving to conception was 107.9 days. The conception rate at first service was 61.9%. Incidence of incorrect AI, most likely due to erroneous heat detection, was 8.9%. Herd related problems affected efficiency of AI in 15.2%. The results show that important factors affecting reproductive performance include nutritional management, oestrus detection and AI technique. (author)

  15. Pyrochemical conversion of weapon-grade plutonium into plutonium oxide

    International Nuclear Information System (INIS)

    One of the objectives of the French-Russian studies conducted from 1993 to 1996 under the AIDA-MOX 1 program was to define a reference process for converting the weapon-grade plutonium excess (designated W-Pu) into plutonium dioxide for further use as MOX fuel in existing nuclear reactors. Among the different selected options, one is performed in molten alkali chlorides bath at high temperature. Several laboratory-scale tests have permitted to demonstrate the feasibility of this conversion in this medium. The main results described in this paper -conversion yield, plutonium purification beside gallium, americium and other impurities, - tend to confirm that pyrochemical processes could offer potential interests if however the plutonium oxide sinterability is proved in next tests.

    2003-09-01

    Two high-pitched and long sustained notes, F5 and A5, were selected from an aria found in ten commercial recordings of G Verdi's opera Aida by ten different sopranos. Both notes were sung without any instrumental accompaniment and with a crescendo. These audio examples were analyzed with regard to fundamental frequency, vibrato rate, vibrato extent, intonation and sound level, and the relationship among these parameters. The results reveal that vibrato rate differed significantly between the tones in most of the singers and confirm Prame's observations that vibrato rate tends to increase exponentially toward the end of tones. Moreover, both vibrato extent and mean F0 often varied systematically with sound level. The regularity of the vibrato tended to be greater at F5 than at A5.

    Among the growing interest about asteroid impact hazard mitigation in our community the Asteroid Impact & Deflection Assessment (AIDA) mission will be the first space experiment to use a kinetic impactor to demonstrate its capability as reliable deflection system [1]. As a part of the AIDA mission, we have proposed a set of two three-axis stabilized 3U CubeSats (with up to 5 science sensors) to simultaneously rendezvous at close range (continued science operation. The science sensors consist of a dual fluxgate magnetometer (MAG), one miniaturized volatile composition analyser (VCA), a narrow angle camera (NAC) and a Video Emission Spectrometer (VES) with a diffraction grating for allowing a sequential chemical study of the emission spectra associated with the impact flare and the expanding plume. Consequently, the different envisioned instruments onboard the CubeSats can provide significant insight into the complex response of asteroid materials during impacts that has been theoretically studied using different techniques [2]. The two CubeSats will remain stowed in CubeSat dispensers aboard the main AIM spacecraft. They will be deployed and commissioned before the AIM impactor reaches the secondary and record the impact event from a closer vantage point than the main spacecraft. The two CubeSats are equipped with relative navigation systems capable of estimating the spacecraft position relative to the asteroids and propulsion system that allow them to operate close to the asteroid bodies. The two CubeSats will rely on mapping data relayed via the AIM main spacecraft but operate autonomously and individually based on schedules and navigation maps uploaded from ground. AIDA's target is the binary Apollo asteroid 65803 Didymos that is also catalogued as Potentially Hazardous Asteroid (PHA) because it experiences close approaches to Earth. Didymos' primary has a diameter of ˜800 meters and the secondary is ˜150 m across. Both bodies are separated about 1.1 km [3

The seroprevalence of HCV in developing countries ranges between 7% and 40%. Risk factors for this infection in the CKD population include the number of blood transfusions, duration of end-stage renal disease (ESRD, and prevalence of HCV in HD. Chronic HCV infection in patients with ESRD is associated with an increase in morbidity and mortality in the pre and post kidney transplant periods. The increase in mortality is directly associated with liver complications and an elevated cardiovascular risk in HCV-infected patients on hemodialysis. Antiviral treatment may improve the prognosis of patients with HCV, and standard interferon remains the cornerstone of treatment. Treatment of HCV in patients with CKD is complex, but achieving a sustained viral response may decrease the frequency of complications after transplantation. It appears that HCV-infected patients who remain on maintenance dialysis are at increased risk of death compared with HCV patients undergoing renal transplantation.Keywords: hepatitis C virus, chronic kidney disease, hemodialysis, interferon

    The Ediacaran of Uruguay has been regarded as containing a significant geological and paleontological record, which would make these successions critical to unraveling diverse aspects regarding the assembly of southwestern Gondwana and to understanding the conditions surrounding the rise of animal life in a period punctuated by drastic paleoenvironmental changes. However, a review of currently available data leads to the conclusion that, although variable, the stratigraphy, distribution and age of these units remain ambiguous. The same is true for existing basin models and tectonic evolution, which show different and sometimes contradicting supporting evidence. Here, we propose that the Ediacaran record consists of the Maldonado Group (Playa Hermosa, Las Ventanas and San Carlos formations), and the Tacuarí, Barriga Negra, Rocha and Sierra de Aguirre formations. The Arroyo del Soldado Group (Yerbal, Polanco Limestones and Cerro Espuelitas formations) and the Arroyo de la Pedrera Group (Piedras de Afilar and Cerro Victoria formations) were likely deposited between 700 and 1000 Ma. The best available radiometric age constraints indicate intense magmatic-tectonic activity occurred between 600 and 560 Ma, incompatible with previous models suggesting a stable, Atlantic-type passive margin on this portion of southwestern Gondwana. Further research is needed in order to firmly establish a consistent litho- and chronostratigraphic framework; particularly, before attempting any regional or global correlation, and inferences on global paleoenvironmental and paleobiological events.

  19. Factors that affect the quality and efficiency of artificial insemination in oestrus synchronization programmes in dairy cattle

    International Nuclear Information System (INIS)

    Experiments were performed during a three-year period in order to identify the factors affecting quality and efficiency of artificial insemination (AI) when it is used in cattle subjected to oestrus induction and synchronization (OIS) programmes. The study took place in the Western part of the country and 3 herds with a total of 6357 animals were used. The first study was a survey to evaluate the factors affecting the efficiency of AI in OIS. The second study examined the effects of body condition score (BCS) and three different regimes of OIS on the results of AI. Progesterone levels were measured in blood and milk using radioimmunoassay to determine the incidence of acyclic animals in the herds. Data were recorded and analysed using the artificial insemination database application (AIDA) and further statistical analyses were done using Systat. The results found in the survey showed a low conception rate (18%) and a great variability in the period from calving to conception (154 ± 98.11 days). The latter parameter was significantly different between herds (P<0.001). A high percentage of animals selected for OIS programmes (37%) showed a poor BCS (<2.5 on a scale of 1-5). Motility of semen used for AI was low (<30%) in 47% of the samples evaluated. The results from progesterone measurements demonstrated that the reasons for poor fertility were low accuracy in oestrus detection, poor response to treatment for OIS, non-fertilization, embryo mortality and functional disturbances present after treatment. Under our field conditions during the dry season, acyclicity (anoestrus) is a frequent problem in primiparous cows and in those with poor BCS. The BCS in heifers and the quality of different treatments had a significant effect on the conception rate. These results confirm that the use of progesterone measurement together with data management using AIDA is a very appropriate way to evaluate and improve the quality and efficiency of AI in OIS programmes.

  20. Use of progesterone measurement to monitor artificial insemination, reproductive functions and pregnancy in Tunisian cattle

    International Nuclear Information System (INIS)

    A study was conducted on 924 dairy cows subjected to artificial insemination (AI) in four Tunisian farms. Three milk samples were collected from each cow, at the time of AI (day 0), 12 days after AI and between 22-24 days after AI. A total of 2830 milk samples were collected and progesterone was measured by radioimmunoassay (RIA). Results from samples collected on day 0 (n=1034) revealed that 10.1% of cows was inseminated at improper times, when progesterone level was greater than 1 nmol/L. Results from samples collected 12 days after AI (n=948) allowed distinguishing between cycling cows (progesterone >3 nmol/L, 69.4%) and non-cycling cows (progesterone 3.5 nmol/L were categorized as probably pregnant. The accuracy of these predictions was 96.6 and 73.3%, respectively. The data relating to farms, inseminated females, AI technicians and semen batch were analysed using the Artificial Insemination database Application (AIDA). The conception rate to the first service was 24.8% (n=306) and the overall conception rate from 597 services was 28.3%. The interval from calving to first service was 74.9 ± 35.2 days (n=306) and from calving to conception was 141.5 ± 108.1 days. The use of the progesterone assay methodology together with the AIDA computer database were found to be appropriate tools to help farmers to improve the reproductive management and fertility of dairy cattle subjected to AI.

    Emerald ash borer is an invasive species from Asia. Beauveria bassiana strain L49-1AA is being tested for the control of emerald ash borer in Canada, using an autocontamination trapping system. We have developed a simplified allele discrimination polymerase chain reaction (PCR) assay to screen B. bassiana strain, L49-1AA from other Beauveria species by targeting the inter-strain genetic differences in 5' end of EF1-α gene of the genus Beauveria. A single nucleotide polymorphism (SNP) site, T→C was identified only in L49-1AA and was used to develop a simplified allele discrimination polymerase chain reaction (PCR) assay based on a modified allelic inhibition of displacement activity (AIDA) approach for distinguishing B. bassiana L49-1AA from all background Beauveria isolates. The SNP site was employed to design inner primers but with a deliberate mismatch introduced at the 3' antepenultimate from the mutation site in order to maximize specificity and detection efficiency. Amplification was specific to L49-1AA without cross-reaction with DNA from other Beauveria strains. In addition, the designed primers were also tested against environmental samples in L49-1AA released plots and observed to be highly efficient in detecting and discriminating the target strain, L49-1AA from both pure and crude DNA samples. This new method can potentially allow for more discriminatory tracking and monitoring of released L49-1AA in our autocontamination and dissemination projects for managing EAB populations. Additionally, the modified-AIDA format has potential as a tool for simultaneously identifying and differentiating closely related Beauveria species, strains/isolates as well as general classification of other pathogens or organisms.

  2. Use of milk progesterone radioimmunoassay and computer applications for community based reproductive health services in smallholder dairy farms of Bangladesh

    International Nuclear Information System (INIS)

    We trained veterinarians, inseminators and farmers to increase their skills and compliance with project activities, used AIDA Asia (a computer application) to record and evaluate fertility of bulls and performance of inseminators, introduced measurement of progesterone (P4) in milk by radioimmunoassay (RIA) to detect artificial insemination (AI) done at incorrect time and non-pregnant cows, and adopted community-based veterinary services for the management of dairy cattle health and reproduction. Training inseminators increased their skills in doing AI correctly and training veterinarians improved their confidence in the management of reproductive problems in cows. Training farmers increased their compliance to adopt the interventions that were introduced. Milk preserved with sodium azide maintained stable P4 concentrations for at least two weeks. Milk P4 concentration was intermediate (≥1 - 1 nmol/L) P4 concentration in milk on day 22.24 after AI, indicating non-pregnancy. More than 12% of cows that did not return to heat by 35.60 days after AI were non-pregnant upon rectal palpation. One-hundred and thirty-eight such cows were examined and 52% were anoestrous, 11% were repeat breeders, 14% had uterine infections and 17.4% had escaped oestrus detection. Various treatment regimes were tested for reproductive problems including anoestrus, repeat breeding and uterine infections, and those proven to be successful were adopted of wider application. Zebu bulls achieved 3.5% higher conception rate (50.8%; n 1275) than did crossbred bulls (47.3%; n = 1256). Conception rates achieved by individual inseminators ranged between 45.5% and 54.1%. In conclusion, milk progesterone RIA identified AIs done at the incorrect time and nonpregnant cows; on-farm veterinary services identified non-detected oestrous cows, which could be treated and inseminated; and AIDA Asia proved useful in evaluating fertility of bulls and skills of inseminators.

  5. The effect of organic coating on the heterogeneous ice nucleation efficiency of mineral dust aerosols

    International Nuclear Information System (INIS)

    The effect of organic coating on the heterogeneous ice nucleation (IN) efficiency of dust particles was investigated at simulated cirrus cloud conditions in the AIDA cloud chamber of Forschungszentrum Karlsruhe. Arizona test dust (ATD) and the clay mineral illite were used as surrogates for atmospheric dust aerosols. The dry dust samples were dispersed into a 3.7 m3 aerosol vessel and either directly transferred into the 84 m3 cloud simulation chamber or coated before with the semi-volatile products from the reaction of α-pinene with ozone in order to mimic the coating of atmospheric dust particles with secondary organic aerosol (SOA) substances. The ice-active fraction was measured in AIDA expansion cooling experiments as a function of the relative humidity with respect to ice, RHi, in the temperature range from 205 to 210 K. Almost all uncoated dust particles with diameters between 0.1 and 1.0 μm acted as efficient deposition mode ice nuclei at RHi between 105 and 120%. This high ice nucleation efficiency was markedly suppressed by coating with SOA. About 20% of the ATD particles coated with a SOA mass fraction of 17 wt% were ice-active at RHi between 115 and 130%, and only 10% of the illite particles coated with an SOA mass fraction of 41 wt% were ice-active at RHi between 160 and 170%. Only a minor fraction of pure SOA particles were ice-active at RHi between 150 and 190%. Strong IN activation of SOA particles was observed only at RHi above 200%, which is clearly above water saturation at the given temperature. The IN suppression and the shift of the heterogeneous IN onset to higher RHi seem to depend on the coating thickness or the fractional surface coverage of the mineral particles. The results indicate that the heterogeneous ice nucleation potential of atmospheric mineral particles may also be suppressed if they are coated with secondary organics

    Separation of particles that play a role in cloud activation and ice nucleation from interstitial aerosols has become necessary to further understand aerosol-cloud interactions. The pumped counterflow virtual impactor (PCVI), which uses a vacuum pump to accelerate the particles and increase their momentum, provides an accessible option for dynamic and inertial separation of cloud elements. However, the use of a traditional PCVI to extract large cloud hydrometeors is difficult mainly due to its small cut-size diameters (dynamics simulations were initially carried out to guide the design of the IS-PCVI. After fabrication, a series of validation laboratory experiments were performed coupled with the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) expansion cloud simulation chamber. In the AIDA chamber, test aerosol particles were exposed to the ice supersaturation conditions (i.e., RHice > 100 %), where a mixture of droplets and ice crystals was formed during the expansion experiment. In parallel, the flow conditions of the IS-PCVI were actively controlled, such that it separated ice crystals from a mixture of ice crystals and cloud droplets, which were of diameter ≥ 10 µm. These large ice crystals were passed through the heated evaporation section to remove the water content. Afterwards, the residuals were characterized with a suite of online and offline instruments downstream of the IS-PCVI. These results were used to assess the optimized operating parameters of the device in terms of (1) the critical cut-size diameter, (2) the transmission efficiency and (3) the counterflow-to-input flow ratio. Particle losses were characterized by comparing the residual number concentration to the rejected interstitial particle number concentration. Overall results suggest that the IS-PCVI enables inertial separation of particles with a volume-equivalent particle size in the range of ~ 10-30 µm in diameter with small inadvertent intrusion (~  5 %) of unwanted

  7. Comparative Transcriptome Analysis Reveals Cool Virulence Factors of Ralstonia solanacearum Race 3 Biovar 2.

    Fanhong Meng

    Full Text Available While most strains of the plant pathogenic bacterium Ralstonia solanacearum are tropical, the race 3 biovar 2 (R3bv2 subgroup attacks plants in cooler climates. To identify mechanisms underlying this trait, we compared the transcriptional profiles of R. solanacearum R3bv2 strain UW551 and tropical strain GMI1000 at 20°C and 28°C, both in culture and during tomato pathogenesis. 4.2% of the ORFs in the UW551 genome and 7.9% of the GMI1000 ORFs were differentially expressed by temperature in planta. The two strains had distinct transcriptional responses to temperature change. GMI1000 up-regulated several stress response genes at 20°C, apparently struggling to cope with plant defenses. At the cooler temperature, R3bv2 strain UW551 up-regulated a cluster encoding a mannose-fucose binding lectin, LecM; a quorum sensing-dependent protein, AidA; and a related hypothetical protein, AidC. The last two genes are absent from the GMI1000 genome. In UW551, all three genes were positively regulated by the adjacent SolI/R quorum sensing system. These temperature-responsive genes were required for full virulence in R3bv2. Mutants lacking lecM, aidA, or aidC were each significantly more reduced in virulence on tomato at 20°C than at 28°C in both a naturalistic soil soak inoculation assay and when they were inoculated directly into tomato stems. The lecM and aidC mutants also survived poorly in potato tubers at the seed tuber storage temperature of 4°C, and the lecM mutant was defective in biofilm formation in vitro. Together, these results suggest novel mechanisms, including a lectin, are involved in the unique temperate epidemiology of R3bv2.

    We present an analysis of the gas-phase oxygen abundances of a sample of 28 galaxies in the local Universe (z < 0.02) hosting Type Ia Supernovae (SNe Ia). The data were obtained with the 4.2m William Herschel Telescope (WHT). We derive local oxygen abundances for the regions where the SNe Ia exploded by calculating oxygen gradients through each galaxy (when possible) or assuming the oxygen abundance of the closest HII region. The sample selection only considered galaxies for which distances not based on the the SN Ia method are available. Then, we use a principal component analysis to study the dependence of the absolute magnitudes on the color of the SN Ia, the oxygen abundances of the region where they exploded, and the stretch of the SN light curve. We demonstrate that our previous result suggesting a metallicity-dependence on the SN Ia luminosity for not-reddened SNe Ia (Moreno-Raya et al. 2016) can be extended to our whole sample. These results reinforce the need of including a metallicity proxy, such...

  12. Agrobacterium mediated transformation of brassica juncea (l.) czern with chitinase gene conferring resistance against fungal infections

    International Nuclear Information System (INIS)

    Brassica juncea (Czern and Coss., L.) is an important oilseed crop. Since it is attacked by several bacterial and fungal diseases, therefore, we developed an easy and simple protocol for the regeneration and transformation of B. juncea variety RAYA ANMOL to give rise to transgenic plants conferring resistance against various fungal diseases. The transformation was carried out using Agrobacterium with Chitinase gene. This gene was isolated from Streptomyces griseus HUT6037. We used two types of explants for transformation i.e. hypocotyls and cotyledons. Only hypocotyls explants showed good results regarding callus initiation. Different hormonal concentrations were applied i.e. BAP 2, 4 and 6 mgL-1 and NAA 0.1, 0.2 and 0.3 mgL-1. However, high transformation efficiency was observed by supplementing the medium with combination of 2 mgL-1 BAP and 0.2 mgL-1 for initiation of callus. Similarly 10 mgL-1 kanamycin and 200 mgL-1 cefotaxime also proved successful for the selection of transformed callus. In order to confirm the presence of transgenic callus Polymerase chain reaction was performed using specific primers for Chitinase gene. (author)

    Full Text Available Non-value-adding activities are pure waste during the construction process. However, most of the construction practitioner does not realise that most of the activities performed during the construction process add no value to their project. A total of 375 numbers of questionnaires distributed to the Developer, Jabatan Kerja Raya, Consultants and Contractors. The study found that awareness by construction participants in Malaysia to take actions against non-value-adding activities during the construction process is relatively low. Through analysed by using the Pareto Chart, it has been found that defects and waiting time are two categories of non-value-adding activities that need to be prioritised by the industry. It is also found that non-value-adding activities most frequently occurred during structural and architectural work. This paper also reviewed on the causes of non-value-adding activities and discussed its effect towards time, cost, quality and productivity of the construction project. This paper is also important to give clearness and broader understandings on this form of waste other than material waste.

    Full Text Available In Surakarta and its surroundings (Solo Raya, there exists more than 400 Small-Medium Enterprises (SMEs that produce finished products of rattan. Due to the high procurement cost as total operational cost of raw rattan distribution network from the sources, e.g. Borneo and Celebes to the rattan industries, the competitiveness of their products is lower than products from other countries. Therefore, to overcome the problem, those costs should be reduced for example by aggregating the demand of rattan industries. This police needs to be supported by the warehouse for storing and distributing raw rattan. Hence, this research aims to develop a facility location-allocation model so that total supply chain costs, including raw rattan procurement costs as well as facilities opening and closing costs can be minimized. The location-allocation model will be presented in a mixed integer non-linear programming model and solved using MS-Excel Solver. The results are number and location of the warehouse along with the raw rattan allocation in the warehouse to ensure raw rattan supply for rattan industries.

    Full Text Available This paper reviews the development of oil palm with linkages to biofuel in Indonesia and analyzes the associated environmental and socioeconomic impacts. We selected three plantation study sites in West Papua (Manokwari, West Kalimantan (Kubu Raya, and Papua (Boven Digoel to assess the impacts. Research findings indicate that the development of oil palm in all three sites has caused deforestation, resulting in significant secondary external impacts such as water pollution, soil erosion, and air pollution. In terms of social impacts, many stakeholder groups, i.e., employees, out-growers, and investing households, report significant gains. However, we found these benefits were not evenly distributed. Other stakeholders, particularly traditional landowners, experienced restrictions on traditional land use rights and land losses. We observed increasing land scarcity, rising land prices, and conflicts over land in all sites. Three major trade-offs are associated with the development of oil palm plantations, including those related to biofuels: unevenly distributed economic benefits are generated at the cost of significant environmental losses; there are some winners but also many losers; and economic gains accrue at the expense of weak rule of law. To reduce the negative impacts and trade-offs of oil palm plantations and maximize their economic potential, government decision makers need to restrict the use of forested land for plantation development, enforce existing regulations on concession allocation and environmental management, improve monitoring of labor practices, recognize traditional land use rights, and make land transfer agreements involving customary land more transparent and legally binding.

Sin embargo, las raíces teóricas de esta experiencia histórica, lejos de implementar los principios típicos del keynesianismo, se asentaron sobre unas bases de marcado carácter neoclásico. A través del conocido como Modelo Rehn-Meidner, posteriormente afianzado por el llamado Modelo EFO, la socialdemocracia sueca estableció un marco de política fiscal y monetaria restrictiva en el que se desarrolló una política salarial solidaria cimentada en un poderoso sindicalismo y un sólido sistema corporativista de negociación colectiva centralizada. Así, mediante la paulatina igualación y la contención de los salarios, se buscaba estimular la productividad, mantener a raya los costes laborales y facilitar la concentración y la centralización del capital. El objetivo final era favorecer la competitividad del sector exportador sueco con el fin de asegurar una rentabilidad y un ritmo de acumulación adecuados.

    The purpose of this paper is to study and analyse the factors affecting customer decisions in using electricity at peak-load hours (between 17.00 to 22.00 WIB) and their behaviors towards electricity conservation in Indonesian household. The underlying rationale is to influence a reduction in energy consumption by stimulating energy saving behaviors, thereby reducing the impact of energy use on the environment. How is the correlation between the decisions in using electricity during peak load hours with the household customer's behavior towards saving electricity? The primary data is obtained by distributing questionnaires to customers of PT. PLN Jakarta Raya and Tangerang Distribution from Household segment. The data is analysed using the Structural Equation Model (SEM) and AMOS Software. The research is finding that all factors (Personal, Social, PLN Services, Psychological, and Cultural) are positively influence customer decision in using electricity at peak load hours. There is a correlation between the decisions in using electricity during peak load hours with the household customer's behavior towards saving electricity.

    Mercury (Hg) is a heavy metal that, once in the environment, is bioaccumulated and biomagnified through food chain impacting ecosystems. The aim of this study was to evaluate total Hg (T-Hg) concentrations in individuals along Cauca and Magdalena Rivers in Colombia, where most gold mining activities take place. A total of 1,328 hair samples were collected and analyzed for T-Hg using atomic absorption spectroscopy. T-Hg concentrations ranged from 0.01 to 20.14 μg/g. Greatest levels were detected in La Raya (5.27 ± 0.32 μg/g), Achi (2.44 ± 0.22 μg/g), and Montecristo (2.20 ± 0.20 μg/g), places that are located near gold mines. Concentrations decreased with the distance from main mining areas. Only 0.75% of the individuals had T-Hg levels above 10 μg/g. Men had significantly higher T-Hg levels than women, and correlation analysis revealed moderately weak but significant relationships between T-Hg and weight (R = 0.111, P mining, monitoring, and educational programs are necessary to protect health of people living near Colombian rivers.

    Anthocyanin dye was extracted from petal of Hibiscus rosasinensis (Bunga Raya) and doped into sol-gel based matrix to investigate an effect of pH change on its optical properties. Sol-gel matrix based on Vinyl triethoxysilene (VTES) as a precursor was prepared through Sol-gel process at pH 7. The sol was doped with 0.1% of Anthocyanin and the same amount of dye was also dissolved in ethanol as a comparative sample. Hydrochloric Acid, HCl and Tetramethylammonium Hydroxide, TMAH were used to change the pH value by adding them at various concentrations into each sample. The emission spectra and chemical structures of the samples were measured by Spectrofluorometer and Fourier Transform Infrared (FTIR) respectively. When excited at 410 nm, two emission peaks at about 492 and 574 nm were observed for Anthocyanin in acidic environment both in ethanol and VTES sol. In base environment however, only Anthocyanin dissolved in ethanol produced emission peak with a single peak at about 539 nm. The sensitivity of Anthocyanin dye toward pH changes in VTES open a possibility to use it as sensing element in which sol-gel based matrix are known to have higher mechanical strength and thermal stability.

    Full Text Available Drought is one of the complex environmental factors affecting growth and yield of sorghum in arid and semi-arid areas of the world. Sixteen elite sorghum (Sorghum bicolor (L Moench genotypes were evaluated for their genetic potential to drought tolerance at callus induction and plant regeneration stage for drought tolerance. The non-ionic water soluble polymer polyethylene glycol (PEG of molecular weight 6000 was used as osmoticum to simulate water stress. The factorial experiment was laid down in a completely randomized design which comprised of a combination of two factors (genotypes and five PEG stress level; 0, 0.5, 1.0, 1.5, and 2.0% (w/v treatments. Data were recorded for callus induction efficiency, callus fresh weight, embryogenic callus percentage and plant regeneration percentage. Significant differences were observed among the genotypes, treatments and their interactions for the evaluated plant traits suggesting a great amount of variability for drought tolerance in sorghum. The correlation analysis also revealed strong and significant association between embryogenic callus percent and plant regeneration percent as well as between embryogenic callus percent and plant regeneration percent. By taking into consideration all the measured traits, Mann Whitney rank sum test revealed that 76T1#23 and Teshale followed by Meko, Gambella-1107 and Melkam showed better drought stress tolerance. Therefore they are recommended to be used as parents for genetic analysis, gene mapping and improvement of drought tolerance while Chelenko, Hormat and Raya appear to be drought sensitive.

The extracts were obtained from the following plants: Salvia officinalis, Lippia citriodora, Pelargonium graveolens and Punica granatum. The size distributions of the GNPs were measured using three different methods: dynamic light scattering, nanoparticle-tracking analysis and analysis of scanning electron microscopy images. The three methods yielded similar size distributions. Biocompatibility was examined by correlation of L-cell growth in the presence of different amounts of GNPs. All GNPs showed good biocompatibility and good stability for over 3 weeks. Therefore, they can be used for imaging and drug-delivery applications in the human body. High-resolution transmission electron microscopy was used to view the shapes of the larger GNPs, while infrared spectroscopy was employed to characterize the various functional groups in the organic layer that stabilize the particles. Finally, active ingredients in the plant extract that might be involved in the formation of GNPs are proposed, based on experiments with pure antioxidants that are known to exist in that plant.

  8. Archaeometric analyses of white glazes used in Islamic glazed pottery by using a portable XRF and XRD analyzer

    International Nuclear Information System (INIS)

    We have carried out on-site nondestructive analyses of the white glazes of Islamic pottery excavated at the Fort of Raya in Egypt using a portable X-ray fluorescence spectrometer (p-XRF) and a portable X-ray diffractometer (p-XRD). It is expected that the systematic chemical analysis of the various types of Islamic white glazed pottery provides the archaeological information such as the production area, the production period and production technique. In this report, we analyzed the various Islamic potteries such as the luster-painted pottery and the so-called Fayyumid glazed pottery. As for the result of XRF analysis, it was found that the content of Pb, Sn, Ca were useful to characterize the white glaze. The luster-painted pottery which was produced in the 9th to 10th centuries in Iraq and the so-called Fayyumid glazed pottery which was probably produced in the 10th to 12th centuries in Egypt have differences in their chemical compositions. On the basis of their compositional differences, the production area or date of the plain opaque glazed pottery which has little typological evidences can be estimated. Furthermore, the cause of opacity in white glaze was identified as cassiterite (SnO2) using the p-XRD. (author)

  12. K-Ar geochronologic evidence for a triassic metamorphic event in the main Chiloe Island, south-central Chile

    International Nuclear Information System (INIS)

    Pioneers geological reconnaissance studies in the Chiloe Archipelago recognised a Palaeozoic metamorphic basement (Saliot, 1969; Watters and Fleming, 1972; Valenzuela, 1982; Valdivia, 1986). Currently in progress geologic studies (Munoz et al., 1999, Duhart et al., 2000; Antinao et al., 2000) interpreted these rocks as part of the Bahia Mansa Metamorphic Complex (Duhart et al., 2000), well exposed to the north and equivalent to the 'Serie Occidental' (Aguirre et al., 1972). Geochronologic data set indicate that this complex evolved during Devonian to Triassic times. In the main Chiloe Island, this metamorphic complex is mainly conform by metasedimentary and metavolcanic rocks covered by Tertiary sedimentary and volcanic rocks and Quaternary glacial, fluvial, estuarine, beach, eolian and fluvial deposits. According to north-west and north-south lineament observed in satellite images, regional magnetic maps and topographic features, the main Chiloe island have been divide in northern, central and southern segments (Munoz et al., 1999). These lineaments are interpreted as regional faults but their ages and cinematic are not well constrained. The central segment was interpreted as an uplifted tectonic block and recent studies in the northern part of this segment have identified an intrusive body herein named as 'Metalqui Pluton'. Although the age of this pluton is unknown yet, Cretaceous intrusive rocks in the same tectonic setting of the Metalqui Pluton have been reported in the Valdivia area (Munizaga et al., 1988; Duhart et al., 1998). Previous U-Pb radiometric ages for detrital zircons from pelitic schists in the northern segment indicated a maximum sediment deposition age during Early to Middle Devonian (Duhart et al., 1999). Also, Triassic K-Ar and 40Ar/39Ar ages have been determined for the main metamorphic and tectonic event. This contribution report Triassic K-Ar ages for the central segment and discuss their regional significance (au)

  14. Burnup measurements of leader fuel elements

    International Nuclear Information System (INIS)

    Some time ago the CCHEN authorities decided to produce a set of 50 low enrichment fuel elements. These elements were produced in the PEC (Fuel Elements Plant), located at CCHEN offices in Lo Aguirre. These new fuel elements have basically the same geometrical characteristics of previous ones, which were British and made with raw material from the U.S. The principal differences between our fuel elements and the British ones is the density of fissile material, U-235, which was increased to compensate the reduction in enrichment. Last year, the Fuel Elements Plant (PEC) delivered the shipment's first four (4) fuel elements, called leaders, to the RECH1. A test element was delivered too, and the complete set was introduced into the reactor's nucleus, following the normal routine, but performing a special follow-up on their behavior inside the nucleus. This experimental element has only one outside fuel plate, and the remaining (15) structural plates are aluminum. In order to study the burnup, the test element was taken out of the nucleus, in mid- November 1999, and left to decay until June 2000, when it was moved to the laboratory (High Activity Cell), to start the burnup measurements, with a gamma spectroscopy system. This work aims to show the results of these measurements and in addition to meet the following objectives: (a) Visual test of the plate's general condition; (b) Sipping test of fission products; (c) Study of burn-up distribution in the plate; (d) Check and improve the calculus algorithm; (e) Comparison of the results obtained from the spectroscopy with the ones from neutron calculus

Para abordar el problema se tomó como punto de partida las experiencias periodsticas vivenciadas en cibermedios zulianos (Faras y Prieto, 2006, 2007; Mogollón y Prieto, 2006 y el perfil del ciberperiodista definido por Albarrán (2008, Aguirre (2006, Saba (2006, Camus (2002 y Gil (1999. Esto implicó describir y caracterizar los equipos de profesionales que integran los cibermedios de la región zuliana en función de aportar a la configuración del perfil del nuevo periodista que pretenda desempeñarse con acierto en el ciberespacio. Desde el punto de vista metodológico, se trató de una investigación descriptiva de carácter cuantitativo con diseño transeccional donde se aplicó como instrumento la encuesta. Entre las conclusiones de la investigación destacan que las competencias ciberperiodsticas en su mayora están instrumentalizadas y asociadas al manejo de editores de texto y datos, as como Internet, siendo estas herramientas suficientes para cubrir las expectativas de sus labores, revelando en este sentido estar muy lejos de los constructos teórico-éticos que deben fundamentar el ciberperiodismo. Predomina en las ciberredacciones del estado Zulia profesionales jóvenes del género masculino egresados en el último lustro, y existe una falta de consenso en las denominaciones de cargos y funciones.

La técnica fue la observación documental, a través de la revisión de textos y otros documentos necesarios para conceptualizar la categoría objeto de estudio; asimismo, fuentes electrónicas. La contrastación teórica realizada dejó en evidencia que las universidades realizan esfuerzos por cumplir con acciones de responsabilidad social que beneficien a la comunidad tanto interna como externa, no obstante carecen de recursos económicos para los planes y proyectos programados, debido a la reformulación presupuestaria. En conclusión, las universidades están sustentadas en pilares éticos donde se ven apoyadas en el compromiso hacia la docencia, investigación y extensión, por tanto no basta con la transferencia de conocimientos teóricos o técnicos sino se ejerce la responsabilidad social bajo una perspectiva del compromiso de los principios y dimensiones de ella, vinculándose a la coherenciadel comportamiento ético individual como capacidad de interrelación del personal dentro y fuera de ella, del tal manera que se genera un vinculo con la universidad-sociedad-empresa generando así una triangulación por el bienestar responsable de la colectividad para garantizar el alcance del bien sustentable.

  19. Airborne hygrometer calibration inter-comparison against a metrological water vapour standard

    Water vapour is the most important atmospheric greenhouse gas, which causes a major feedback to warming and other changes in the climate system. Knowledge of the distribution of water vapour and its climate induced changes is especially important in the upper troposphere and lower stratosphere (UT/LS) where vapour plays a critical role in atmospheric radiative balance, cirrus cloud formation, and photochemistry. But, our understanding of water in the UT/LS is limited by significant uncertainties in current UT/LS water measurements. One of the most comprehensive inter-comparison campaigns for airborne hygrometers, termed AQUAVIT (AV1) [1], took place in 2007 at the AIDA chamber at the Karlsruhe Institute of Technology (KIT) in Germany. AV1 was a well-defined, referred, blind inter-comparison of 22 airborne field instruments from 17 international research groups. One major metrological deficit of AV1, however, was, that no traceable reference instrument participated in the inter-comparison experiments and that the calibration procedures of the participating instruments were not monitored or interrogated. Consequently a follow-up inter-comparison was organized in April 2013, which for the first time also provides a traceable link to the international humidity scale. This AQUAVIT2 (AV2) campaign (details see: http://www.imk-aaf.kit.edu/aquavit/index.php/Main_Page) was again located at KIT/AIDA and organised by an international organizing committee including KIT, PTB, FZJ and others. Generally AV2 is divided in two parallel comparisons: 1) AV2-A uses the AIDA chamber for a simultaneous comparison of all instruments (incl. sampling and in-situ instruments) over a broad range of conditions characteristic for the UT/LS; 2) AV2-B, about which this paper is reporting, is a sequential comparison of selected hygrometers and (when possible) their reference calibration infrastructures by means of a chilled mirror hygrometer traced back to the primary National humidity standard

    Full Text Available RESUMEN: Las excavaciones de Emiliano Aguirre en As Gándaras de Budiño inauguran los trabajos en el yacimiento más importante del Paleolítico gallego y uno de los más importantes de la Península Ibérica. Desde este momento, las polémicas por su cronología y su industria lítica fueron frecuentes. Las excavaciones de Aguirre afectaron exclusivamente a niveles “coluviales”, donde la industria estaba desplazada de su posición original. El intento de datación de K. W. Butzer, mediante la técnica del C14, deparó resultados totalmente anómalos. Apoyándose en las mencionadas dataciones, situaron la ocupación achelense del yacimiento en un momento avanzado del Pleistoceno Superior. Ahora bien, ni el rango de aplicación del método de datación, ni el propio contexto de la industria (posición secundaria, justifican la adscripción cronológica propuesta. Trabajos posteriores, de Julio Vidal Encinas, ponen de manifiesto la existencia de industrias achelenses en un contexto estratigráfico diferente (terraza fluvial y sin alteraciones postdeposicionales importantes. La posición morfoestratigráfica de la terraza es propia de la segunda mitad del Pleistoceno Medio. Así mismo, las características de estas industrias son idénticas a las de cualquier otro yacimiento achelense mesopleistoceno de la Península Ibérica. En este artículo analizamos los materiales (inéditos procedentes del “Locus V” de las excavaciones de Vidal Encinas. Esta industria procede de niveles análogos a los identificados en las excavaciones de Aguirre. La comparación con los materiales, recuperados en niveles fluviales, sugiere que se trata de conjuntos semejantes, es decir, que forman parte de una misma ocupación (en sentido amplio. Las únicas diferencias apreciables derivan de los procesos sedimentarios (clasificación por tamaños principalmente, que intervinieron en la deposición de la industria de los niveles “coluviales”.ABSTRACT: Emiliano

    Full Text Available The aim of this study was to investigate oxidation of SOA formed from ozonolysis of α-pinene and limonene by hydroxyl radicals. This paper focuses on changes of particle volatility, using a Volatility Tandem DMA (VTDMA set-up, in order to explain and elucidate the mechanism behind atmospheric ageing of the organic aerosol. The experiments were conducted at the AIDA chamber facility of KIT in Karlsruhe and at the SAPHIR chamber of FZJ in Jülich. A fresh SOA was produced from ozonolysis of α-pinene or limonene and then aged by enhanced OH exposure. As an OH-radical source in the AIDA-chamber the ozonolysis of tetramethylethylene (TME was used while in the SAPHIR-chamber the OH was produced by natural light photochemistry. A general feature is that SOA produced from ozonolysis of α-pinene and limonene initially were rather volatile and becomes less volatile with time in the ozonolysis part of the experiment. Inducing OH chemistry or adding a new portion of precursors made the SOA more volatile due to addition of new semi-volatile material to the aged aerosol. The effect of OH chemistry was less pronounced in high concentration and low temperature experiments when lower relative amounts of semi-volatile material were available in the gas phase. Conclusions drawn from the changes in volatility were confirmed by comparison with the measured and modelled chemical composition of the aerosol phase. Three quantified products from the α-pinene oxidation; pinonic acid, pinic acid and methylbutanetricarboxylic acid (MBTCA were used to probe the processes influencing aerosol volatility. A major conclusion from the work is that the OH induced ageing can be attributed to gas phase oxidation of products produced in the primary SOA formation process and that there was no indication on significant bulk or surface reactions. The presented results, thus, strongly emphasise the importance of gas phase oxidation of semi- or intermediate-volatile organic compounds

    Aftershocks from the magnitude Mw 5.8 August 23, 2011, central Virginia earthquake were recorded using an unusually dense array of seismometers in what has been termed an AIDA (Aftershock Imaging with Dense Arrays) deployment. Over 200 stations were deployed in the epicentral region of this event to a) more precisely determine hypocentral locations, b) more accurately define velocity structure in the aftershock zone, c) characterize propagation characteristics of the crust in the area, and d) image geologic structures in the hypocentral volume with reflection techniques using aftershocks as sources. The AIDA-Virginia experiment successfully recorded a large number of aftershocks from which local tomographic velocity estimates and accurate hypocentral locations were obtained. These results facilitated the use of aftershocks as sources for reflection imaging. In this study we demonstrate how earthquake sources recorded by surface arrays can be treated using the imaging techniques associated with Vertical Seismic Profiling (VSP), in particular a variant known as Reverse VSP (RVSP). The central VSP processing algorithms used for this study are VSP normal moveout (VSPnmo) and VSP-to-Common Reflection Point (CRP). Applying these techniques to individual aftershocks from the Virginia experiment results in 3D reflection images of structural complexity in the immediate vicinity of the aftershocks. The most prominent feature observed on these 3D images is a strong moderately east-dipping reflector at a depth of approximately 6 to 8 km that directly underlies, and is continuous beneath, the more steeply dipping aftershock zone. We interpret this reflector as part of a complex imbricate thrust sequence associated with Paleozoic convergence during the Appalachian orogeny. Its apparent continuity beneath the fault zone implied by the aftershock's hypocenters suggests that this inferred fault zone has little or no cumulative offset, supporting the speculation that this event

    A new heterogeneous ice nucleation parameterization that covers a wide temperature range (-36 °C to -78 °C) is presented. Developing and testing such an ice nucleation parameterization, which is constrained through identical experimental conditions, is critical in order to accurately simulate the ice nucleation processes in cirrus clouds. The surface-scaled ice nucleation efficiencies of hematite particles, inferred by ns, were derived from AIDA (Aerosol Interaction and Dynamics in the Atmosphere) cloud chamber measurements under water subsaturated conditions that were realized by continuously changing temperature (T) and relative humidity with respect to ice (RHice) in the chamber. Our measurements showed several different pathways to nucleate ice depending on T and RHice conditions. For instance, almost independent freezing was observed at -60 °C < T < -50 °C, where RHice explicitly controlled ice nucleation efficiency, while both T and RHice played roles in other two T regimes: -78 °C < T < -60 °C and -50 °C < T < -36 °C. More specifically, observations at T colder than -60 °C revealed that higher RHice was necessary to maintain constant ns, whereas T may have played a significant role in ice nucleation at T warmer than -50 °C. We implemented new ns parameterizations into two cloud models to investigate its sensitivity and compare with the existing ice nucleation schemes towards simulating cirrus cloud properties. Our results show that the new AIDA-based parameterizations lead to an order of magnitude higher ice crystal concentrations and inhibition of homogeneous nucleation in colder temperature regions. Our cloud simulation results suggest that atmospheric dust particles that form ice nuclei at lower temperatures, below -36 °C, can potentially have stronger influence on cloud properties such as cloud longevity and initiation when compared to previous parameterizations.

  6. Integrating laboratory and field data to quantify the immersion freezing ice nucleation activity of mineral dust particles

    Full Text Available Data from both laboratory studies and atmospheric measurements are used to develop a simple parametric description for the immersion freezing activity of natural mineral dust particles. Measurements made with the Colorado State University (CSU continuous flow diffusion chamber (CFDC when processing mineral dust aerosols at a nominal 105% relative humidity with respect to water (RHw are taken to approximate the immersion freezing nucleation activity of particles. Ice active frozen fractions vs. temperature for dusts representative of Saharan and Asian desert sources were consistent with similar measurements in atmospheric dust plumes for a limited set of comparisons available. The parameterization developed follows the form of one suggested previously for atmospheric particles of non-specific composition in quantifying ice nucleating particle concentrations as functions of temperature and the total number concentration of particles larger than 0.5 μm diameter. Such an approach does not explicitly account for surface area and time dependencies for ice nucleation, but sufficiently encapsulates the activation properties for potential use in regional and global modeling simulations, and possible application in developing remote sensing retrievals for ice nucleating particles. A correction factor is introduced to account for the apparent underestimate (by approximately 3, on average of the immersion freezing fraction of mineral dust particles for CSU CFDC data processed at an RHw of 105% vs. maximum fractions active at higher RHw. Instrumental factors that affect activation behavior vs. RHw in CFDC instruments remain to be fully explored in future studies. Nevertheless, the use of this correction factor is supported by comparison to ice activation data obtained for the same aerosols from Aerosol Interactions and Dynamics of the Atmosphere (AIDA expansion chamber cloud parcel experiments.

    A minor fraction of atmospheric aerosol particles, so-called ice-nucleating particles (INPs), initiates the formation of the ice phase in tropospheric clouds and thereby markedly influences the Earth's weather and climate systems. Whether an aerosol particle acts as an INP depends on its size, morphology and chemical compositions. The INP fraction of certain aerosol types also strongly depends on the temperature and the relative humidity. Because both desert dust and soil dust aerosols typically comprise a variety of different particles, it is difficult to assess and predict their contribution to the atmospheric INP abundance. This requires both accurate modelling of the sources and atmospheric distribution of atmospheric dust components and detailed investigations of their ice nucleation activities. The latter can be achieved in laboratory experiments and parameterized for use in weather and climate models as a function of temperature and particle surface area, a parameter called ice-nucleation active site (INAS) density. Concerning ice nucleation activity studies, the soil dust is of particular interest because it contains a significant fraction of organics and biological components, both with the potential for contributing to the atmospheric INP abundance at relatively high temperatures compared to mineral components. First laboratory ice nucleation experiments with a few soil dust samples indicated their INP fraction to be comparable or slightly enhanced to that of desert dust. We have used the AIDA (Aerosol Interaction and Dynamics in the Atmosphere) cloud simulation chamber to study the immersion freezing ability of four different arable soil dusts, sampled in Germany, China and Argentina. For temperatures higher than about -20°C, we found the INP fraction of aerosols generated from these samples by a dry dispersion technique to be significantly higher compared to various desert dust aerosols also investigated in AIDA experiments. In this contribution, we

    Full Text Available The AquaVIT-1 Intercomparison of Atmospheric Water Vapor Measurement Techniques was conducted at the aerosol and cloud simulation chamber AIDA at the Karlsruhe Institute of Technology, Germany, in October 2007. The overall objective was to intercompare state-of-the-art and prototype atmospheric hygrometers with each other and with independent humidity standards under controlled conditions. This activity was conducted as a blind intercomparison with coordination by selected referees. The effort was motivated by persistent discrepancies found in atmospheric measurements involving multiple instruments operating on research aircraft and balloon platforms, particularly in the upper troposphere and lower stratosphere where water vapor reaches its lowest atmospheric values (less than 10 ppm. With the AIDA chamber volume of 84 m3, multiple instruments analyzed air with a common water vapor mixing ratio, either by extracting air into instrument flow systems, locating instruments inside the chamber, or sampling the chamber volume optically. The intercomparison was successfully conducted over 10 days during which pressure, temperature, and mixing ratio were systematically varied (50 to 500 hPa, 185 to 243 K, and 0.3 to 152 ppm. In the absence of an accepted reference instrument, the reference value was taken to be the ensemble mean of a core subset of the measurements. For these core instruments, the agreement between 10 and 150 ppm of water vapor is considered good with variation about the reference value of about ±10% (±1σ. In the region of most interest between 1 and 10 ppm, the core subset agreement is fair with variation about the reference value of ±20% (±1σ. The upper limit of precision was also derived for each instrument from the reported data. These results indicate that the core instruments, in general, have intrinsic skill to determine unknown water vapor mixing ratios with an accuracy of at least ±20%. The implication for atmospheric

The major mechanism of action of isoflurane is modulation of the γ-amino butyric acid (GABAA receptor-chloride channel, mediating inhibitory synaptic transmission. Animal studies have shown that isoflurane does not cause cell death, but it does inhibit cell growth and causes long-term hippocampal learning deficits. As there are no studies characterizing the effects of isoflurane on electrophysiological aspects of long-term potentiation (LTP in the hippocampus, it is important to determine whether isoflurane alters the characteristic responses of hippocampal afferents to cornu ammonis region 3 (CA3. We investigated the effects of isoflurane on adult male rats during in vivo induction of LTP, using the mossy fiber pathway, the lateral perforant pathway, the medial perforant pathway, and the commissural CA3 (cCA3 to CA3, with intracranial administration of Ringer’s solution, naloxone, RS-aminoindan-1, 5-dicarboxylic acid (AIDA, or 3-[(R-2-carboxypiperazin-4-yl]-propo-2-enyl-1-phosphonic acid (CPP. Then, we compared these responses to published electrophysiological data, using sodium pentobarbital as an anesthetic, under similar experimental conditions. Our results showed that LTP was exhibited in animals anesthetized with isoflurane under vehicle conditions. With the exception of AIDA in the lateral perforant pathway, the defining characteristics of the four pathways appeared to remain intact, except for the observation that LTP was markedly reduced in animals

    The reinforcement used in soil for construction of roads on the soft clay is very important as it will determine the level of service of the road after it was built. Damage or defects on the road surface to be an indicator of the level of the road has dropped and shows the deformation of the road. For this research, an analysis has carried out on the long-term effect of trial test road constructed on Batu Pahat Soft Clay (BPSC) at RECESS UTHM. Through this research, the reinforcement using Rawell Geosynthetic Clay Liner (RGCL) was the best with the stability is 14964 N, a low flow is 2.69mm, stiffness modulus is 1766 MPa, the peak load is 739.4 N and a lower horizontal deformation which is 1.71 µm compared Woven Geotextile section and section without geotextile [1] [9]. In terms of deformation can be seen clearly from physical observations that section without geotextile suffered significant damage than others. Settlement of road can also be analyzed by a longitudinal section that plotted based on the result of leveling work. After that, settlements are more visible way on the right side of the road trial. Through lab tests conducted, it indicate that the coring samples obtained from sites of each section meets the specifications set by the Jabatan Kerja Raya (JKR) in terms of stability, flow and stiffness [1]. Through this study, a trial road built on soft soil can be used as a test site because of the uniqueness of these roads which has three different types of reinforcements.

  14. Hibiscus Rosa Sinensis Leaves: Analysis Of Proximate, Antioxidant Activities And Inorganic Compound

    International Nuclear Information System (INIS)

    A variety of herbal plants species has been used in traditional medicine. Most of these plants contained several potent bio-active ingredients and nutrients that could give potential positive effects to the health such as antioxidant and antipyretic. Hibiscus rosa sinensis, commonly known as Bunga raya, have similar concoction characteristic to tea which contain antioxidants that help to control cholesterol. In addition, mucilage that was found in the leaves could helps to reduce extreme body heat during fever (which potentially acts as an antipyretic). Therefore, this preliminary study on the fresh and dried H. rosa sinensis leaves was carried out to analyze and identify the nutrients content, anti-oxidants and inorganic material. Total phenolic content (TPC) method was used for both fresh and dried leaves prior to the antioxidant activities of DPPH free radicals scavenging and ferric ion reducing antioxidant power (FRAP) as to confirm the existence of antioxidant constituents. Meanwhile, the composition of heavy metals was studied using inductively coupled plasma mass spectrometry (ICP-MS). The proximate analysis of the fresh leaves showed the presence of moisture content (9.03 %), protein (10.44 %), fat (6.43 %), crude fiber (11.55 %), ash (11.22 %) and carbohydrate (51.33 %). Meanwhile, the inorganic contents are as follows: cadmium (Cd), chromium (Cr), arsenic (As), nickel (Ni), lead (Pb), iron (Fe) and zinc (Zn). Furthermore, the antioxidant activities of FRAP and DPPH showed that dried leaves of H. rosa sinensis was higher than the fresh leaves (p < 0.05) irrespective of any solvent used. The positive correlation between TPC and two other antioxidant activities of DPPH and FRAP (p < 0.05) indicates the presence of antioxidant components in the acetone and water extracts. Therefore, the high availability of essential nutritional component, anti-oxidants and low concentration of hazardous inorganic matter in H. rosa sinensis leaves enable it to be used as one

    Full Text Available As the era of globalisation has progressed, the free-trade paradigm – in which the role of government in every aspect of economic development is minimised, replaced by the power of the free market – has inevitably spread across countries throughout the world. Despite the positive outcomes that can be obtained from the idea of free liberalisation in achieving economic growth and opportunities, this paper will propose that governments must continue to have a strong role in their countries’ economies, particularly in developing countries such as Indonesia. This argument is justified on the basis of the threat that free trade poses to some informal sectors called micro and small and medium enterprises (MSMEs, which have commonly shown low levels of competitiveness in the global market. Thus their very survival heavily depends on government involvement. The Indonesian government has launched many policies to help SMEs become and remain more competitive; for example, the Technology for Regions Program (Iptekda, which combines state support and a market-based approach for MSMEs’ empowerment. This paper conducts a case study of the Iptekda program for the empowerment of MSMEs in Malang Raya. The research will address two issues: why government intervention is still required for MSE capacity-building; and how the program may help MSMEs improve their capacity and competitiveness. To answer these questions, this paper will apply a qualitative approach that uses in-depth interview with the owners of five MSMEs. The results reveal that MSMEs benefit from the program in terms of improved productivity, marketing and insights into MSMEs as an economic sector. The research limitation is that it consists solely of qualitative findings; the findings need to be combined with quantitative data for more-reliable results. Replication of this study using larger samples and a broader geographic base is suggested for promoting programs to empower MSMEs in

    Full Text Available Se presenta claves taxonómicas basadas en características morfológicas dentarias externas e internas, que permiten el reconocimiento de cada orden, familia y género de los batoídeos conocidos en Chile. En algunos casos, como en las familias Rhinobatidae, Torpedinidae, Narcinidae, Myliobatidae, Mobulidae, Dasyatidae y Urotrygonidae, las claves permiten el reconocimiento específico pero, en otros casos, sólo se puede discriminar hasta género, dadas las limitaciones impuestas por los conocimientos existentes. Estas claves son una herramienta complementaria a la diagnosis de rayas y están orientadas al reconocimiento de fragmentos dentales, hallazgos paleontológicos de dientes así como para las piezas dentales asociadas con la mandíbula. De esta manera, se entrega un apoyo taxonómico nuevo con características dentales diferentes a las consideradas actualmente para este superorden.A series of keys with external and internal dental morphologic features for the identification of each order, family and genus of rays and skates of the batoids known in Chile, are presented. In the case of families Rhinobatidae, Torpedinidae, Narcinidae, Myliobatidae, Mobulidae, Dasyatidae and Urotrygonidae, an identification at the species level is possible. In other cases, due to limitations imposed by the existing knowledge, only discrimination up to genus is allowed. These keys are a complementary tool for the diagnosis of rays suitable for the identification of dental fragments, paleontological discoveries of teeth as well as for jaw teeth. This tool offers a novel taxonomic support, which includes dental features different from those considered nowadays for this superorder.

    Excessive sedimentation and flood hazard are common in ephemeral streams which are characterized by flashy floods. The purposes of this study was to investigate the temporal variability of bio-climatic factors in controlling sediment supply to downstream channel reaches and the effect of bridges on local hydro-geomorphic conditions in causing the excess sedimentation and flood hazard in ephemeral rivers of the Raya graben (northern Ethiopia). Normalized Difference Vegetation Index (NDVI) was analyzed for the study area using Landsat imageries of 1972, 1986, 2000, 2005, 2010, and 2012). Middle term, 1993-2011, daily rainfall data of three meteorological stations, namely, Alamata, Korem and Maychew, were considered to analyse the temporal trends and to calculate the return time intervals of rainfall intensity in 24 hours for 2, 5, 10 and 20 years using the log-normal and the Gumbel extreme events method. Streambed gradient and bed material grain size were measured in 22 river reaches (at bridges and upstream). In the study catchments, the maximum NDVI values were recorded in the time interval from 2000 to 2010, i.e. the decade during which the study bridges experienced the most severe excess sedimentation problems. The time series analysis for a few rainfall parameters do not show any evidence of rainfall pattern accountable for an increase in sediment delivery from the headwaters nor for the generation of higher floods with larger bedload transport capacities. Stream bed gradient and bed material grain size data were measured in order to investigate the effect of the marked decrease in width from the wide upstream channels to the narrow recently constructed bridges. The study found the narrowing of the channels due to the bridges as the main cause of the thick sedimentation that has been clogging the study bridges and increasing the frequency of overbank flows during the last 15 years. Key terms: sedimentation, ephemeral streams, sediment size, bridge clogging

    Full Text Available Inhabitants of a building are difficult to escape particulate matter emission. Within this condition, buildings should have vertical element that could block the dispersion of particulate matter to living spaces. Vegetation, a part of vertical elemen for fencing, is considered to do this task. The use of vegetation is chosen with reference to nature and behaviour of particulate matter. Earlier research found that dispersion of particulate matter is mostly at lower atmospheric layer and that particulate matter could be deposited. Therefore, low growing vegetation or climbing plants with particular leaf condition to encourage deposition is predicted suitable. Four vegetation was examined: Duranta repens, Polyscias fruticosa, Stephanotis floribunda and Scindapsus sp. As a preliminary study, there is no valid conclusion could be made from this experiment. However, there are indications that Duranta repens and Stephanotis floribunda block and deposit slightly more particulate matter than the two others. Abstract in Bahasa Indonesia : Polusi particulate matter atau partikel halus tidak hanya terjadi di jalan raya, tetapi juga masuk ke dalam bangunan yang terletak di sepanjang jalan. Oleh karenanya, bangunan seyogyanya memiliki elemen vertikal yang mampu bertugas menghalangi masuknya polusi partikel halus. Salah satu kemungkinan penggunaan elemen vertikal, yaitu tanaman yang ditempatkan pada posisi pagar diteliti dalam studi ini. Mempelajari bahwa partikel halus dengan ukuran tertentu dapat diendapkan dan penyebarannya umumnya terjadi pada lapisan udara rendah, maka studi terhadap tanaman semak atau perdu atau tanaman rambat dengan jenis permukaan daun tertentu lebih diutamakan. Empat jenis tanaman diuji kemampuannya, yaitu: Duranta repens, Polyscias fruticosa, Stephanotis floribunda and Scindapsus sp. Sebagai studi yang sangat awal, masih belum ada hasil valid yang ditawarkan, namun setidaknya ditemukan indikasi bahwa Duranta repens and Stephanotis

    This study aimed to find out the effect of plant growth-promoting rhizobacteria (PGPR; Azospirillum brasilense and Azotobacter vinelandii) either alone or in combination with different doses of nitrogen and phosphate fertilizers on growth, seed yield, and oil quality of Brassica carinata (L.) cv. Peela Raya. PGPR were applied as seed inoculation at 10(6) cells/mL(-1) so that the number of bacterial cells per seed was 2.6 × 10(5) cells/seed. The chemical fertilizers, namely, urea and diammonium phosphate (DAP) were applied in different doses (full dose (urea 160 kg ha(-1) + DAP 180 kg ha(-1)), half dose (urea 80 kg ha(-1) + DAP 90 kg ha(-1)), and quarter dose (urea 40 kg ha(-1) + DAP 45 kg ha(-1)). The chemical fertilizers at full and half dose significantly increased the chlorophyll, carotenoids, and protein content of leaves and the seed yield (in kilogram per hectare) but had no effect on the oil content of seed. The erucic acid (C22:1) content present in the seed was increased. Azospirillum performed better than Azotobacter and its effect was at par with full dose of chemical fertilizers (CFF) for pigments and protein content of leaves when inoculated in the presence of half dose of chemical fertilizers (SPH). The seed yield and seed size were greater. Supplementing Azospirillum with SPH assisted Azospirillum to augment the growth and yield, reduced the erucic acid (C22:1) and glucosinolates contents, and increased the unsaturation in seed oil. It is inferred that A. brasilense could be applied as an efficient bioinoculant for enhancing the growth, seed yield, and oil quality of Ethiopian mustard at low fertilizer costs and sustainable ways.

    Full Text Available Variation Order (VO is a common phenomenon in construction projects. It involves an amendment of the original scope of work as in the contract. VO is caused from various factors. Variations often cause disputes and dissatisfactions among the parties involved in construction projects. Thus, it is very important to control VOs in a construction project. For this, the first step is to uncover and understand the causes and effects of VO. Hence, the aim of this study is to determine the significant causes and effects of VO in construction projects. Data collection involved the survey with a structured questionnaire consisting of 18 causes and 9 effects of variation orders identified through comprehensive literature review. Survey was carried out among client representatives, consultants and contractors involved in handling projects of Malaysian Public Works Department (PWD known as Jabatan Kerja Raya Malaysia (JKR. A total of 101 completed questionnaire sets were collected against 200 questionnaires distributed among the practitioners. Collected questionnaires were analyzed with statistical software package SPSS and Average Index formula. The results of the study showed that in Malaysia’s JKR projects often variation orders are occurred; these VO’s are majorly caused because of unavailability of equipment, poor workmanship and design complexity. While most significant effects of VO on the projects are increased project cost, delay in completion and logistic delays. Early participation of professionals may be beneficial in reducing the occurrence of variations. Also, improved design and avoiding frequent design changes will be very effective in controlling the problem of variations.

    This paper presents the results of mass spectrometric investigations of the OH-initiated oxidative aging of α-pinene SOA under simulated tropospheric conditions at the large aerosol chamber facility AIDA, Karlsruhe Institute of Technology. In particular, the OH-initiated oxidation of pure pinic and pinonic acid, two well-known oxidation products of α-pinene, was investigated. Two complementary analytical techniques were used, on-line atmospheric pressure chemical ionization/mass spectrometry (APCI/MS) and filter sampling followed by liquid chromatography/mass spectrometry (LC/ESI-MS). The results show that 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA), a very low volatile α-pinene SOA product and a tracer compound for terpene SOA, is formed from the oxidation of pinonic acid and that this oxidation takes place in the gas phase. This finding is confirmed by temperature-dependent aging experiments on whole SOA formed from α-pinene, in which the yield of MBTCA scales with the pinonic acid fraction in the gas phase. Based on the results, several feasible gas-phase radical mechanisms are discussed to explain the formation of MBTCA from OH-initiated pinonic acid oxidation.

  6. Anaphe - OO libraries and tools for data analysis

    International Nuclear Information System (INIS)

    The Anaphe project is an ongoing effort to provide an Object Oriented software environment for data analysis in HENP experiments. A range of commercial and public domain libraries is used to cover basic functionalities; on top of these libraries a set of HENP-specific C++ class libraries for histogram management, fitting, plotting and ntuple-like data analysis has been developed. In order to comply with the user requirements for a command-line driven tool, the authors have chosen to use a scripting language (Python) as the front-end for a data analysis tool. The loose coupling provided by the consequent use of (AIDA compliant) Abstract Interfaces for each component in combination with the use of shared libraries for their implementation provides an easy integration of existing libraries into modern scripting languages thus allowing for rapid application development. This integration is simplified even further using a specialised toolkit (SWIG) to create 'shadow classes' for the Python language, which map the definitions of the Abstract Interfaces almost at a one-to-one level. The authors will give an overview of the architecture and design choices and will present the current status and future developments of the project

    On 4 December 2002 at Hampton University, we completed processing the 'straws' for the Barrel TRT. The straws are plastic tubes 4 mm in diameter and 1.44 m long. More than 52 thousand straws will be used to build the drift tube detectors in the Barrel TRT. The picture shows some members of the Hampton production team ceremonially cutting the last straw to its final precise length. The production team, responsible for processing 64 thousand straws, included Jacquelyn Hodges, Carolyn Griffin, Princess Wilkins, Aida Kelly, Alan Fry, and (not pictured) Chuck Long, Nedra Peeples, and Hilda Williams. The straws have a cosmopolitan history. First, plastic film from a U.S. company was shipped to Russia to be coated with conductive materials and adhesive. The coated film was slit into long ribbons and sent to the UK to be wound into tubes. The tubes were then sent to two ATLAS collaborators in Russia, PNPI (Gatchina) and JINR (Dubna), where they were reinforced with carbon fibres to make them stiff and accuratel...

  8. Efficiency of the deposition mode ice nucleation on mineral dust particles

    Full Text Available The deposition mode ice nucleation efficiency of various dust aerosols was investigated at cirrus cloud temperatures between 196 and 223 K using the aerosol and cloud chamber facility AIDA (Aerosol Interaction and Dynamics in the Atmosphere. Arizona test dust (ATD as a reference material and two dust samples from the Takla Makan desert in Asia (AD1 and the Sahara (SD2 were used for the experiments at simulated cloud conditions. The dust particle sizes were almost lognormally distributed with mode diameters between 0.3 and 0.5 μm and geometric standard deviations between 1.6 and 1.9. Deposition ice nucleation was most efficient on ATD particles with ice-active particle fractions of about 0.6 and 0.8 at an ice saturation ratio SiSiSi. This indicates that deposition ice nucleation on mineral particles may not be treated in the same stochastic sense as homogeneous freezing. The suggested formulation of ice activation spectra may be used to calculate the formation rate of ice crystals in models, if the number concentration of dust particles is known. More experimental work is needed to quantify the variability of the ice activation spectra as function of the temperature and dust particle properties.

    The purpose of the present study was to monitor a diver's ability to perform maximal face-immersion apnea throughout the competitive season. A male, world-class apnea diver was followed for 1 year (from March 2012 to March 2013). During this period he was tested six times. Each test session involved the measurements of the pulmonary function and respiratory muscle strength. In addition, the ability to perform maximal face-immersion apnea was also explored. The results of face-immersion apnea durations showed a continuous improvement throughout the preparation period 1 with the peak in the main competition period and a decline during the competition period 2 and the transition period. It seemed that the training periodization was successful by producing the diver's peak performance level at the main diving competition i.e. the 2012 AIDA Freediving World Championships. In conclusion, the study shows that changes in training interventions due to seasonal training periodization could be accompanied by changes in a diver's ability to perform the maximal face-immersion apnea. However, further research is needed to establish the influences of individual components of apnea training on a diver's performance. PMID:26887906

    2012-11-01

    Full Text Available Using the aerosol and cloud simulation chamber AIDA we investigated the laser filament induced particle formation in ambient air, humid synthetic air, humid nitrogen, argon-oxygen mixture, and pure argon in order to simulate the particle formation under realistic atmospheric conditions as well as to investigate the influence of typical gas-phase atmospheric constituents on the particle formation. Terawatt laser plasma filaments generated new particles in the size range 3 to 130 nm with particle production rates ranging from 1 × 107 to 5 × 109 cm−3 plasma s−1. In all cases the particle formation rates increased exponentially with the water content of the gas mixture. Furthermore, the presence of a few ppb of trace gases like SO2 and α-pinene clearly enhanced the particle yield by number, the latter also by mass. Our findings suggest that new particle formation is efficiently supported by acids generated by the photo-ionization of both major and minor components of the air, including N2, NH3, SO2 and organics.

    Field-testing kinetic impactors to deflect potentially hazardous asteroids (PHAs) is essential to better understand the challenges of future asteroid impact threat mitigation. The Asteroid Impact and Deflection Assessment mission (AIDA, Cheng et al. 2016), a collaborative effort between NASA and ESA, offers a timely opportunity to validate kinetic impact deflection strategies. Although the main goal of NASA's kinetic impactor (DART) is to change the circumprimary orbit of (65803) Didymos' moonlet, the imparted momentum will also slightly change the heliocentric orbit of the whole binary asteroid system. Given the high degree of non-linearity of the near-Earth dynamical environment, however, even a small change in initial conditions can affect long term predictions of the encounter distances between Didymos and the Earth. Belonging to the dynamical class of PHAs, (65803) Didymos has several encounters with the Earth over the upcoming decades, some of which are closer than 20 lunar distances. In order to confirm that no planetary safety issues arise as a consequence of DART, we conducted a post-mitigation impact risk assessment (PMIRA, Eggl et al. 2015) for the currently foreseen DART impact trajectories. In this contribution we present the latest PMIRA results and discuss the role of ESA's AIM spacecraft in reducing uncertainties arising in the deflection process.

    Today, it is considered state-of-the-art to engineer living organisms for various biotechnology applications. Even though this has led to numerous scientific breakthroughs, the enclosed interior of bacterial cells still restricts interactions with enzymes, pathways and products due to the mass-transfer barrier formed by the cell envelope. To promote accessibility, we propose engineering of biocatalytic reactions and subsequent product deposition directly on the bacterial surface. As a proof-of-concept, we used the AIDA autotransporter vehicle for Escherichia coli surface expression of tyrosinase and fully oxidized externally added tyrosine to the biopolymer melanin. This resulted in a color change and creation of a black cell exterior. The capture of ninety percent of a pharmaceutical wastewater pollutant followed by regeneration of the cell bound melanin matrix through a simple pH change, shows the superior function and facilitated processing provided by the surface methodology. The broad adsorption spectrum of melanin could also allow removal of other micropollutants. PMID:27782179

    The fast turnover of software technologies,in particular in the domain of in teractivity(covering user interface and visualisation)makes it difficult for a small group of people to produce complete and polished software-tools before the underlying technologies make them obsolete.At the HepVis '99 workshop,a working group has been formed to improve the rpoduction of software tools for data analysis in HENP.Beside promoting a distributed development organisation,one goal of the group is to systematically design a set of abstract interfaces based on using modern OO analysis and OO design techniques.An initial domain analysis has come up with several categories(componets)found in typical data analysis tools:historams,Ntuples,Functions,Vectors,Fitter,Plotter,Analyzer and Controller,Special Emphasis was put on reducing the couplings between the categories to a minimum,thus optimising re-use and maintainability of any component individually.The interfaces have been defined in Java and C++ and implementations exist in the form of libraries and tools using C++(Anaphe/Lizard,Openscientist)and Java(Java Analysis Studio),A special implementation aims at accessing the Java Liraries(through their Abstract Interfaces)from C++.This paper giver an overview of the architecture and design of the various components for data analysis as discussed in AIDA.

    In the project of Advanced European Infrastructures for Detectors at Accelerators (AIDA), the Institute of Nuclear Research designed and tested the Totally Active Scintillator Detector (TASD). This paper reports the results of design of TASD prototype and outlines requirements for a test beam at CERN to test these, tentatively planned on the H8 beamline in the North Area, which is equipped with a large aperture magnet. TASD consists of 50 modules of plastic scintillators. Each module is instrumented with one X and one Y plane, with 90 scintillator bars per plane. The bar width, height and length are 1.0 cm, 0.7 cm and 90 cm respectively. The distance between modules can be varied from 0 to 2.5 cm. Other components such as active detectors or passive sheets of material can be inserted in these 2.5 cm gaps if required. The full detector depth can therefore be varied from 75 cm to 200 cm and in its compact form, it is 1 m3 in volume. The paper presents measurement results for the TASD elements that included in the prototype elements (measurement of crosscurrents, the light yield of scintillators, and the characteristics of photodiodes).

    The measurement of atmospheric ice nucleating particles (INP) is still challenging. In the absence of easily applicable INP standards the intercomparison of different methods during collaborative laboratory and field workshops is a valuable tool that can shine light on the performance of individual methods for the measurement of INP [1]. FIN-2 was conducted in March 2015 at the AIDA facility in Karlsruhe as an intercomparison of mobile instruments for measuring INP [2]. FIN-3 was a field campaign at the Desert Research Institutes Storm Peak Laboratory in Colorado in September 2015 [3]. The FRankfurt Ice nucleation Deposition freezinG Experiment (FRIDGE) participated in both experiments. FRIDGE measures ice nucleating particles by electrostatic precipitation of aerosol particles onto Si-wafers in a collection unit, followed by activation, growth, and optical detection of ice crystals on the substrate in an isostatic diffusion chamber [4,5]. We will present and discuss results of our measurements of deposition/condensation INP and of immersion INP with FRIDGE during FIN-2 and FIN-3. Acknowledgements: The valuable contributions of the FIN organizers and their institutions, and of the FIN Workshop Science team are gratefully acknowledged. Our work was supported by Deutsche Forschungsgemeinschaft (DFG) under the Research Unit FOR 1525 (INUIT) and the EU FP7-ENV- 2013 BACCHUS project under Grant Agreement 603445.

  19. Formation of 3-methyl-1,2,3-butanetricarboxylic acid via gas phase oxidation of pinonic acid – a mass spectrometric study of SOA aging

    Full Text Available This paper presents the results of mass spectrometric investigations of the OH-initiated oxidative aging of α-pinene SOA under simulated tropospheric conditions at the large aerosol chamber facility AIDA, Karlsruhe Institute of Technology. In particular, the OH-initiated oxidation of pure pinic and pinonic acid, two well-known oxidation products of α-pinene, was investigated. Two complementary analytical techniques were used, on-line atmospheric pressure chemical ionization/mass spectrometry (APCI/MS and filter sampling followed by liquid chromatography/mass spectrometry (LC/ESI-MS. The results show that 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA, a known and very low volatile α-pinene SOA product, is formed from the oxidation of pinonic acid and that this oxidation takes place in the gas phase. This finding is confirmed by temperature-dependent aging experiments on whole SOA formed from α-pinene, in which the yield of MBTCA scales with the pinonic acid fraction in the gas phase. Based on the results, several feasible gas-phase radical mechanisms are discussed to explain the formation of MBTCA from OH-initiated pinonic acid oxidation.

    2016-01-01

    We define a set of procedures to numerically study the fate of ejecta produced by the impact of an artificial projectile with the aim of deflecting an asteroid. Here we develop a simplified, idealized model of impact conditions that can be adapted to fit the details of specific deflection-test scenarios, such as what is being proposed for the AIDA project. Ongoing studies based upon the methodology described here can be used to inform observational strategies and safety conditions for an observing spacecraft. To account for ejecta evolution, the numerical strategies we are employing are varied and include a large N-Body component, a smoothed-particle hydrodynamics (SPH) component, and an application of impactor scaling laws. Simulations that use SPH-derived initial conditions show high-speed ejecta escaping at low angles of inclination, and very slowly moving ejecta lofting off the surface at higher inclination angles, some of which re-impacts the small-body surface. We are currently investigating the realism...

    International Nuclear Information System (INIS)

    Created in 1976, Cogema provides electric power companies all over the world with expertise in every aspect of the nuclear fuel cycle from mineral exploration through spent fuel reprocessing and recycling. The AIDA-mox2 program brought together Cogema, Minatom and Siemens in order to carry out preliminary design studies for a MOX fuel fabrication plant to be built in Russia. Cogema is one of the 3 companies that agreed to buy uranium produced by dismantling Russian warhead. Since long Cogema has marketed its products and services in Usa through local subsidiaries. Cogema also provides expertise and technologies to several large departments of energy (DOE) cleanup projects. In Asia, nuclear power programs continue to grow significantly. Cogema is a supplier to Japanese power companies in both the front end and back end of the fuel cycle. In 2001 Cogema and Japan Nuclear Fuel Limited (JNFL) signed an agreement for the transfer of MOX fuel fabrication technology in order to support the construction of a plant in Japan. Cogema has been present in South-Korea for more than 20 years, primarily for sales of front end products and services. The national South-Korean utility KHNP chose the cold crucible vitrification process in order to reduce the volumes of effluents, this process has been developed by French Cea and Cogema, a Korean pilot plant has been operating since september 1999.

    BRIKEN is a complex detection system to be installed at the RIB-facility of the RIKEN Nishina Center. It is aimed at the detection of heavy-ion implants, $\\beta$-particles, $\\gamma$-rays and $\\beta$-delayed neutrons. The whole detection setup involves the Advanced Implantation Detection Array (AIDA), two HPGe Clover detectors and a large set of 166 counters of 3He embedded in a high-density polyethylene matrix. This article reports on a novel methodology developed for the conceptual design and optimisation of the 3He-tubes array, aiming at the best possible performance in terms of neutron detection. The algorithm is based on a geometric representation of two selected parameters of merit, namely, average neutron detection efficiency and efficiency flatness, as a function of a reduced number of geometric variables. The response of the detection system itself, for each configuration, is obtained from a systematic MC-simulation implemented realistically in Geant4. This approach has been found to be particularly u...

  3. Bilateral MOX projects for W-grade Pu disposition: Safety implications

    International Nuclear Information System (INIS)

    Beginning from 1992 a number of studies were performed in Russia in the field of peaceful utilization of the excess Weapon-derived Plutonium (W-Pu). Very important results were obtained from Russian-German, Russian-French, Russian-Canadian Feasibility Studies and from the US-Russian Projects. These Studies have demonstrated technical feasibility of W-Pu conversion into MOX-fuel and its utilization in certain power reactors. Technical feasibility implies safety assurance for all stages of W-Pu management. All safety-related aspects (e.g. reactor safety, nuclear criticality, fire and explosion safety, protective barriers reliability, etc.) have to be taken into account for implementation of W-Pu utilization through MOX-route. Safety has to be guarantied for such W-Pu-related activities as: Plutonium interim storage; Plutonium conversion from metal to oxide; MOX fuel fabrication and transportation; MOX irradiation in power reactor; MOX spent fuel management; Pu-bearing waste minimization and waste management; Radiological protection of the personnel and environment. Paper addresses to safety-related issues of W-Pu conversion into oxide form and MOX- fuel fabrication. Some results of Russian-German and Russian-French (AIDA-MOX 1) Studies are discussed. (author)

  4. Application of a computer database and progesterone radioimmunoassay for the assessment of factors affecting conception rate in crossbred cows following artificial insemination under field conditions

    International Nuclear Information System (INIS)

    The study was conducted to identify various factors affecting the success of artificial insemination (AI) and to improve reproductive efficiency through better management, AI services and application of progesterone radioimmunoassay (RIA). Data pertaining to 568 inseminations in cattle were collected according to the protocol of the Artificial Insemination Database Application (AIDA). Of these, 149 cows were subjected to clinico-gynaecological examination and milk samples were collected for progesterone assay to determine possible causes of infertility and the success of various interventions. Highest conception rates were obtained when the cows were inseminated during standing oestrus (51.6%), 18-23 h after the onset of oestrus (48.8%), by inseminators with a professional degree (48.7%) and using the best quality semen (51%). The main causes of repeat breeding identified during clinical and laboratory studies were: (a) inappropriate timing of AI in 48% of cows (milk progesterone concentration >1.0 nmol/L at AI); (b) subnormal luteal phase in 15% (plasma progesterone concentration 36 h) in 15%; and (d) sub-clinical microbial endometritis in 18%. Use of poor quality semen also contributed to repeat breeding. (author)

    The Anaple project is an ongoing effort to provide an Object Oriented software environment for data analysis in HENP experiments,A range of commercial and public domain libraries is used to cover basic functionalities;on top of these libraries a set of HENP-sepcific C++ class libraries for histogram management fitting,plotting and ntuple-like data analysis has been developed .In order to comply with the user requireements for a command-line driven tool,we have chosen to use a scripting language(Python)as the fromt-ent for a data analysis tool.The loose coupling provided by the consequent use of (AIDA compliant)Abstract Interfaces for each component in combination with the use of shared libraries for their implementation provies an easy integration of existing libraries into modern scipting languages thus allowing for rapid application development.This integration is simplified even further suing a specialised toolkit(SWIG)to create" shadow Classes"for the Python language,which map the definitions of the Abstract Interfaces almost at a one-to-one level.This paper will give an overview of the architecture and design choices and will present the current status and future developments of the project.

  6. Homogeneous nucleation rates of nitric acid dihydrate (NAD at simulated stratospheric conditions – Part II: Modelling

    O. Möhler

    2006-01-01

    Full Text Available Activation energies ΔGact for the nucleation of nitric acid dihydrate (NAD in supercooled binary HNO3/H2O solution droplets were calculated from volume-based nucleation rate measurements using the AIDA (Aerosol, Interactions, and Dynamics in the Atmosphere aerosol chamber of Forschungszentrum Karlsruhe. The experimental conditions covered temperatures T between 192 and 197 K, NAD saturation ratios SNAD between 7 and 10, and nitric acid molar fractions of the nucleating sub-micron sized droplets between 0.26 and 0.28. Based on classical nucleation theory, a new parameterisation for ΔGact=A×(T ln SNAD−2+B is fitted to the experimental data with A=2.5×106 kcal K2 mol−1 and B=11.2−0.1(T−192 kcal mol−1. A and B were chosen to also achieve good agreement with literature data of ΔGact. The parameter A implies, for the temperature and composition range of our analysis, a mean interface tension σsl=51 cal mol−1 cm−2 between the growing NAD germ and the supercooled solution. A slight temperature dependence of the diffusion activation energy is represented by the parameter B. Investigations with a detailed microphysical process model showed that literature formulations of volume-based (Salcedo et al., 2001 and surface-based (Tabazadeh et al., 2002 nucleation rates significantly overestimate NAD formation rates when applied to the conditions of our experiments.

    2003-01-01

    Full Text Available In situ Fourier transform infrared (FTIR extinction spectra of supercooled H2SO4/H2O and HNO3/H2O solution droplets were recorded in the large coolable aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere of Forschungszentrum Karlsruhe for a range of aerosol compositions and at temperatures extending down to 192 K. The measured spectra were quantitatively analysed in terms of aerosol composition and mass concentration by using Mie theory in combination with published refractive index data as input parameters. Simultaneously, total sulphuric acid and nitric acid mass concentrations from filter analysis and total water concentrations measured with the Lyman-a hygrometer of Forschungszentrum Jülich were used to calculate the aerosol composition at thermodynamic equilibrium inside the aerosol chamber. By comparing these measured aerosol parameters with those retrieved from the analysis of the FTIR spectra, the accuracy of the literature data sets of refractive indices could be assessed. In summary, four data sets were tested in the H2SO4/H2O system as well as two data sets in the HNO3/H2O system, partly revealing significant discrepancies in the retrieved aerosol properties. Potential explanations for these differences are discussed in this paper.

    A library of 4,5-disubstituted 2-aminoimidazole triazole amide (2-AITA) conjugates has been successfully assembled. Upon biological screening, this class of small molecules was discovered as enhanced biofilm regulators through non-microbicidal mechanisms against methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Acinetobacter baumannii (MDRAB), with active concentrations in the low micromolar range. The library was also subjected to synergism and resensitization studies with β-lactam antibiotics against MRSA. Lead compounds were identified that suppress the antibiotic resistance of MRSA by working synergistically with oxacillin, a β-lactam antibiotic resistant to penicillinase. A further structure-activity relationship (SAR) study on the parent 2-AITA compound delivered a 2-aminoimidazole diamide (2-AIDA) conjugate with significantly increased synergistic activity with oxacillin against MRSA, decreasing the MIC value of the β-lactam antibiotic by 64-fold. Increased anti-biofilm activity did not necessarily lead to increased suppression of antibiotic resistance, which indicates that biofilm inhibition and resensitization are most likely occurring via distinct mechanisms.

  11. A Java Program for the Viewing of Ambient Data

    International Nuclear Information System (INIS)

    The BaBar detector system has a large number of sensors and data feeds, called ambient feeds. These feeds are vital to the operation and monitoring of the Pep rings and the BaBar system. In order to more easily monitor these systems a simple web interface to display graphical representations of the data is needed. Towards this end it was decided that using a Java Web Servlet (Sun Microsystems) would be an effective and simple way to achieve this effect. By combining Web Servlets with the Corba Technology (OMG) this provides a way for many people to access data from anywhere in the world. Using this type of program in conjunction with the HEP AIDA systems for graphing makes a powerful tool for the monitoring of the BaBar system. An overview of the BaBar system, and how the Ambient data is given. The uses and limitations of this method for viewing the data as well as examples of other ways to access the data and potential other uses for the servlet are also discussed

    ESA's European Space Astronomy Centre (ESAC), near Madrid, Spain, hosts most of ESA space based missions' scientific archives, in planetary (Mars Express, Venus Express, Rosetta, Huygens, Giotto, Smart-1, all in ESA Planetary Science Archive), in astronomy (XMM-Newton, Herschel, ISO, Integral, Exosat, Planck) and in solar physics (Soho). All these science archives are operated by a dedicated Science Archives and Virtual Observatory Team (SAT) at ESAC, enabling common and efficient design, development, operations and maintenance of the archives software systems. This also ensures long term preservation and availability of such science archives, as a sustainable service to the science community. ESA space science data can be accessed through powerful and user friendly user interface, as well as from machine scriptable interface and through VO interfaces. Virtual Observatory activities are also fully part of ESA archiving strategy and ESA is a very ac-tive partner in VO initiatives in Europe through Euro-VO AIDA and EuroPlanet and worldwide through the IVOA (International Virtual Observatory Alliance) and the IPDA (International Planetary Data Alliance).

    The ice nucleation activities of five different Pseudomonas syringae, Pseudomonas viridiflava and Erwinia herbicola bacterial species and of Snomax™ were investigated in the temperature range between -5 and -15°C. Water suspensions of these bacteria were directly sprayed into the cloud chamber of the AIDA facility of Forschungszentrum Karlsruhe at a temperature of -5.7°C. At this temperature, about 1% of the Snomax™ cells induced immersion freezing of the spray droplets before the droplets evaporated in the cloud chamber. The living cells didn't induce any detectable immersion freezing in the spray droplets at -5.7°C. After evaporation of the spray droplets the bacterial cells remained as aerosol particles in the cloud chamber and were exposed to typical cloud formation conditions in experiments with expansion cooling to about -11°C. During these experiments, the bacterial cells first acted as cloud condensation nuclei to form cloud droplets. Then, only a minor fraction of the cells acted as heterogeneous ice nuclei either in the condensation or the immersion mode. The results indicate that the bacteria investigated in the present study are mainly ice active in the temperature range between -7 and -11°C with an ice nucleation (IN) active fraction of the order of 10-4. In agreement to previous literature results, the ice nucleation efficiency of Snomax™ cells was much larger with an IN active fraction of 0.2 at temperatures around -8°C.

    Experiments in the East Area received their first beams from the PS this week. Theirs is CERN's first accelerator-based physics since LS1 began last year.   For the East Area, the PS performs a so-called slow extraction, where beam is extracted during many revolution periods (the time it take for particles to go around the PS, ~2.1 μs). The yellow line shows the circulating beam current in the PS, decreasing slowly during the slow extraction, which lasts 350 ms. The green line is the measured proton intensity in the transfer line toward the East Area target. Although LHC physics is still far away, we can now confirm that the injectors are producing physics! In the East Area - the experimental area behind the PS - the T9 and T10 beam lines are providing beams for physics. These beam lines serve experiments such as AIDA - which looks at new detector solutions for future accelerators - and the ALICE Inner Tracking System - which tests components for the ALICE experiment. &qu...

    The mass spectral signatures of airborne bacteria were measured and analyzed in cloud simulation experiments at the AIDA (Aerosol Interaction and Dynamics in the Atmosphere) facility. Suspensions of cultured cells in pure water were sprayed into the aerosol and cloud chambers forming an aerosol which consisted of intact cells, cell fragments and residual particles from the agar medium in which the bacteria were cultured. The aerosol particles were analyzed with a high-resolution time-of-flight aerosol mass spectrometer equipped with a newly developed PM2.5 aerodynamic lens. Positive matrix factorization (PMF) using the multilinear engine (ME-2) source apportionment was applied to deconvolve the bacteria and agar mass spectral signatures. The bacteria mass fraction contributed between 75 and 95% depending on the aerosol generation, with the remaining mass attributed to agar. We present mass spectra of Pseudomonas syringae and Pseudomonas fluorescens bacteria typical for ice-nucleation active bacteria in the atmosphere to facilitate the distinction of airborne bacteria from other constituents in ambient aerosol, e.g. by PMF/ME-2 source apportionment analyses. Nitrogen-containing ions were the most salient feature of the bacteria mass spectra, and a combination of C4 H8 N(+) (m/z 70) and C5 H12 N(+) (m/z 86) may be used as marker ions. PMID:26149110

    During the Mid-latitude Airborne Cirrus Properties Experiment (MACPEX) field campaign, the Small Ice Detector version 3 (SID-3) and the NCAR Video Ice Particle Sampler (VIPS) probes were operated onboard the NASA WB-57 aircraft to measure the microphysical properties of small ice particles in midlatitude cirrus clouds. The VIPS was optimized to measure the particle size distribution and projected area properties of ice particles between 20 and 200 microns and measurements agreed well with other microphysical probes. SID-3 measures the forward light scattering pattern from ice particles in the 1 to 100 micron size range. Forward scattering patterns can be used to characterize ice particle shape as well as surface roughness. Scattering patterns appear to be 'speckled' when particles have surface roughness and/or are polycrystalline. Scattering patterns can be used to identify quasi-spherical ice particles as well as particles which are sublimating. Sublimating crystals, spherical ice particles, and particles with surface roughness were all observed by SID-3 during MACPEX. Observed particle properties will be correlated to concurrent atmospheric observations. Measurements from the controlled environment of the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) cloud chamber will be related to atmospheric particle measurements.

    Full Text Available During the past few years, there has been tremendous increase in advertisement expenses all over the world. Therefore, it is important to examine, to investigate and to evaluate the performance of advertisement to reach organizations’ objectives. This paper presents an empirical investigation using highly reliable and efficient method called AIDA, which consists of four factors: attention, interest, desire and action. The study is implemented for one of Iranian food suppliers called TABAROK located in city of Mashad, Iran. The survey selects a sample of 300 regular customers and distributes a standard questionnaire among them. Cronbach alpha has been calculated as 0.93, which is well above the minimum desirable level. Using Spearman correlation test, the study confirms that all four components of the survey influences consumer behavior, positively. The study also indicates that there were some positive and meaningful correlations among various components of the survey. In addition, applying Freedman test indicates that advertisement has the highest impact on convincing consumer to purchase product.

    Extracts from fruit pulps of six female cultivars and two hermaphrodite Portuguese carob trees [(Ceratonia siliqua L., Fabaceae)] exhibited strong antioxidant activity and were rich in phenolic compounds. The extracts decreased the viability of different human cancer cell lines on a dose- and time-dependent manner. Gender and cultivar significantly influenced the chemical content and the biological activities of the extracts. Extracts from hermaphrodite trees had a higher content of phenolic compounds, and exhibited higher antioxidant and cytotoxic activities. Among females, cv. Aida had the highest radical scavenging activity and total content of phenolics, Mulata the highest capacity to inhibit lipid oxidation and Gasparinha the strongest cytotoxic activity on HeLa cells. The decrease in cell viability was associated with apoptosis on HeLa and MDA-MB-231 lines. (+)-Catechin and gallic acid (GA) were the main compounds identified in the extracts, and GA contributed to the antioxidant activity. Our results show that the antioxidant and cytotoxic activities of carob tree fruit pulps are strongly influenced by gender and cultivar, and provide new knowledge about the advantages of hermaphrodite trees over female cultivars, namely, as a source of compounds with biological interest, which may represent an increase of their agronomic interest.

    Diarrhea in pre-weaning and post-weaning piglets is still a frequently occurring disease on scaled farms,and result in great economic losses.Enterotoxigenic Escherichia coli (ETEC) is a major cause,and the virulence factors are the key to its pathogenicity.The traditional and commonly detected pili of ETEC are F4(K88),F5 (K99),F6(987P),F18 and F41,and the enterotoxins include heat-stable STa and STb,heat-labile enterotoxin LT and Stx2e.However,new reports have shown that ETEC strains lacking of recognized fimbriae are becoming increasingly common,which may be linked to the use of vaccines incorporating fimbriated strains,providing selection pressure for the acquisition and carriage of novel,unrecognized virulence genes.Recently,EAST1 (enteroaggregative Escherichia coli heat-stable enterotoxin 1),PAA (porcine attaching and effacing-associated factor),AIDA-I (adhesin involved in diffuse adherence)and intimin encoded by eae (Escherichia coli attaching and effacing) have been reported.Nevertheless,few related data have been available in China; furthermore,the prevention strategies have been devised largely based on the virulence factors.In order to gain more insight into the pathogenesis of colibacillosis in piglets and control the disease,it is of significant importance to track the changes of E.coli virulence factors and antimicrobial resistance,and elucidate the possible relationship between them. Samples were collected by rectum swabs from diarrheal piglets on intensive pig farms of Zhejiang Province.A total of 124 pathogenic isolates were obtained after bacteria isolation,purification,and identification based on the combination of morphology and PCR techniques.The virulence factors were verified by PCR with specific primer pairs.Susceptibility testing was carried out by K-B method,and analyzed by Whonet software.The correction between antibacterial resistance and virulence factors was evaluated by Logistic regression analysis. The PCR results showed that fimbriae

In the last few years, there have been an increasing number of reports about sterile intraocular inflammation and intraocular pressure elevations after intravitreal bevacizumab. In the following case series, we describe the clinical presentation and outcomes of ten consecutive cases of patients developing mild-to-severe sterile intraocular inflammation after intravitreal bevacizumab and their management. Methods: This report presents a retrospective case series. We reviewed the medical records of ten consecutive patients from a group of 46, in whom repackaged bevacizumab in individual aliquots from two vials from the same batch were used. All surgical procedures were performed using standard sterile techniques in the operating room. At each follow-up visit, patients underwent a complete ophthalmological examination including visual acuity assessment, intraocular pressure, biomicroscopy, and posterior fundus examination. Results: Ten patients presented sterile endophthalmitis with an onset time of 3.5±1.95 days. The clinical characteristics were mild pain, slight visual loss, conjunctival hyperemia, and various degrees of intraocular inflammation with microhypopyon. All cultures were negative. All patients were managed with topical steroids and antibiotics, except two, in whom, due to severe vitreous cells, intravitreal antibiotics were

  6. Space-time distribution of ignimbrite volcanism in the southern SMO: From Eocene to Pliocene

    A distinct variation in the age of the ignimbrites of the Sierra Madre Occidental (SMO) is observed in the southern portion, which includes the area between Tepic, Nayarit (-105° W) and Aguascalientes, Ags (-102° W). Older, high-grade ignimbrites are Eocene and occur as scattered outcrops. These are in turn covered by a widespread and voluminous sequence of high-grade ignimbrites and silicic to intermediate lavas that ranges in age from Middle Oligocene to Middle Miocene. The peak of this ignimbrite volcanism was at about 21 Ma to 22 Ma, but there is evidence showing that it initiated since about 30 Ma and ended at about 17.5 Ma. This ignimbrite and lava sequence is in turn covered by another series of lavas, predominantly mafic to intermediate, in the southern part of the area. This latest volcanism represents the initiation of the Mexican Volcanic Belt. Ignimbrite volcanism apparently initiated at the NE part of the study area, and migrated to the SW with time, that is from the area Presa Calles to the valley of Bolaños. Isotopic ages reported on these rocks, cluster in various groups reflecting the time evolution of volcanism. Rocks older than 30 Ma tend to occur on the raised blocks of Sierra de El Laurel and Northern Sierra de Morones, in the eastern part of the area. The interval from 30 to 20 Ma comprises a discontinuous set of ages that are concentrated in the blocks of Southern Sierra de Morones, Tlaltenango, Bolaños and the area around Cinco Minas-San Pedro Analco-Hostotipaquillo. An apparent gap of ages occurs between 12 to 18 Ma, followed by a predominantly mafic volcanism scattered mainly to the south of the area, that represents the transition of SMO to MVB. Finally mafic volcanism of the MVB of 3 to 4 Ma is present in the south, in the area excavated on the vicinity of Rio Grande de Santiago. A similar migration pattern has been reported in general for the whole SMO by Aguirre-Diaz and Labarthe-Hernandez (2003), from NE Chihuahua to SW Nayarit

Two diatom index were applied and revealed that, while the IDG served as base line for initiating the development of evaluation techniques through microalgae, must be supplemented with local diatom index when existent or with local relevant literature. The local index use and its development will allow to select those that best fit for the ecology of our region and to it future implementations as a metric in the evaluation, along with other index, of the ecological status of waters bodies of CNEA sites.

    Braided rivers have received relatively little attention in research and development activities in drylands. However, they strongly impact agroecology and agricultural activities and thereby local livelihoods. The Raya Graben (3750 km² including the escarpment) is a marginal graben of the Ethiopian Rift Valley located in North Ethiopia. In order to study the dynamics of braided rivers and the relationship with biophysical controls, 20 representative catchments were selected, ranging between 15 and 311 km². First, the 2005 morphology (length, area) of the braided rivers was related to biophysical controls (vegetation cover, catchment area and slope gradient in the steep upper catchments and gradient in the graben bottom). Second, the changes in length of the braided rivers were related to vegetation cover changes in the upper catchments since 1972. Landsat imagery was used to calculate the Normalized Difference Vegetation Index (NDVI), and to map vegetation cover and the total length of the braided rivers. Spot CNES imagery available from Google Earth was used to identify the total area of the braided rivers in 2005. A linear regression analysis revealed that the length of braided rivers was positively related to the catchment area (R²=0.32, p<0.01), but insignificantly related to vegetation cover in the upper catchments. However, there is an indication that it is an important factor in the relationship calculated for 2005 (R²=0.2, p=0.064). Similarly, the area occupied by the braided rivers was related to NDVI (R²=0.24, p<0.05) and upper catchment area (R²=0.447, p<0.01). Slope gradient is not an important explanatory factor. This is related to the fact that slope gradients are steep (average of 38.1%) in all upper and gentle (average of 3.4%) in graben bottom catchments. The vegetation cover in the upper catchments shows a statistically insignificant increasing trend (R²=0.73, p=0.067) over the last 40 years, whereas length of rivers in the graben bottom

    Guanajuato has been an important gold and silver mineral district of Mexico since the 16th century until Present. Famous mines such as Rayas, La Valenciana and El Cubo, are part of this important mining development. Stratigraphy and structures are well known, and major faults and vein systems are precisely mapped. The series include a Mesozoic metamorphosed volcano-sedimentary sequence interpreted as a tectonically accreted terrane during Early Cretaceous subduction; a >1000 m thick red beds sequence, apparently Eocene and interpreted originally as molasses posterior to K/T Laramide orogeny, but more probably fanglomerates filling a graben formed during mid-Tertiary extension; an Eocene-Miocene volcanic sequence that accumulated in this tectonic basin and the surrounding area, including andesitic lavas, silicic ignimbrites and surge deposits, and rhyolitic domes. Pyroclastic rocks have not been studied with a volcanological approach, with the purpose of understanding the physical volcanic processes that formed them. Randall (1994) suggested a caldera source for some of them. Our purpose is to describe the volcanic processes involved in the mid-Tertiary units of Guanajuato. There are dacitic and andesitic lavas that were apparently contemporaneous with deposition of the Red Conglomerate of Guanajuato. The ignimbrites correspond to the Sierra Madre Occidental volcanic province. These units were originated as two main pyroclastic densety currents sequences that formed the Loseros-Bufa and the Calderones formations. The former is rhyolitic and the later andesitic-dacitic. Loseros is composed of a series of thin-bedded to laminated pyroclastic surge deposits in continuous and concordant contact with overlying Bufa massive ignimbrite. Bufa ignimbrite is partly welded, with columnar jointing, completely devitrified, and highly silicified by post-deposition hydrothermalism and/or vapor phase alteration. Co-ignimbrite lithic lag breccias are observed at several sites in

    Translocation of absorbed phosphorus (P) from metabolically inactive sites to active sites in plants growing under P deprivation may increase its P utilization efficiency (PUE). Acclimation to phosphate (Pi) starvation may be caused by a differential storage pool of vacuolar P, its release, and the intensity of re-translocation of absorbed P as P starvation inducible environmental cues (PSIEC) from ambient environment. Biomass assay and three P forms, namely inorganic (Pi),organic (Po), and acid-soluble total (Ptas) were estimated in Brassica cultivars exposed to 10 d P deprivation in the culture media. Considering that -δPi/δt denotes the rate of Pi release, Pi release velocity (RSPi) was determined as the tangent to the equations obtained for Pi f(t) at the mean point in the period of greatest Pi decrease, whereas the inverse of the RSPi was art estimate of the internal Pi buffering capacity (IBCPi). Inter cultivar variations in size of the non-metabolic Pi pool,RSPi, re-translocation of Pi from less to more active metabolic sites, and preferential Pi source and sink compartments were evaluated under P starvation. The cultivar 'Brown Raya' showed the highest Pi storage ability under adequate external P supply, and a more intensive release than 'Rain Bow' and 'Dunkled' under P stress. Cultivar 'B.S.A' was inferior to 'Con-1'in its ability to store and use Pi. Roots and upper leaves were the main sink of Pi stored in the lower and middle leaves of all cultivars and showed lower IBCPi and larger RSPi values than lower and middle leaves. In another trial, six cultivars were exposed to P-free nutrition for 29 d after initial feeding on optimum nutrition for 15 d. With variable magnitude, all of the cultivars re-translocated P from the above ground parts to their roots under P starvation, and [P] at 44 d after transplanting was higher in developing leaves compared with developed leaves. Under P deprivation, translocation of absorbed P from metabolically inactive to

    EL primer hecho que debe mencionarse a propósito de la esvástica, cruz gamada o gammadion es que, hasta el presente, no se ha encontrado nunca en monumentos prehistóricos en el Próximo Oriente ni en objetos anteriores a la Edad del Hierro en Occidente. En pinturas paleolíticas se han hallado abundantes signos gráficos, sobre cuya interpretación distan de estar de acuerdo los prehistoriadores: rayas, series de trazos, de puntas, flechas, signos tectiformes, series de arcos de circunferencia, arpones, rombos, rejillas, cruces y aspas. Pero nunca esvásticas. El carácter de todos los signos que hemos citado, a excepción de los tectiformes y de los arcos concéntricos de circunferencia, permite atribuir su hallazgo al azar o al gesto instintivo. La esvástica es tan marcadamente intencional que sólo una idea concreta puede darle origen. Cabría suponer que nació de superposiciones de grecas, si no fuera más antigua que ellas (las más antiguas esvásticas conocidas datan de finales del cuarto milenio antes de nuestra Era. También sucede lo mismo con las ruedas de trazos sigmoideos, de los que pudiera ser una simplificación, pero esas ruedas son también posteriores. En cuanto a su parentesco con los símbolos solares (disco, disco con rayos, disco con dos cruces, la normal y el aspa, trazos convergentes solos señalando la irradiación de luz y calor es poco menos que nulo. El origen de la esvástica es desconocido. En cuanto a su distribución, a partir de un centro que cabe situar entre el Cáucaso y Mesopotamia -tanto hacia Oriente, hasta Japón (trayectoria que no vamos a estudiar, como hacia Occidente-, lo mismo puede proceder del fenómeno de «invención simultánea» que de la «migración» del símbolo.

  14. An outbreak of contagious bovine pleuropneumonia (CBPP) and post outbreak sero-surveillance in Eritrea

    International Nuclear Information System (INIS)

    At the end of 2002 contagious bovine pleuropneumonia (CBPP) was never reported in Eritrea for the last 20 to 30 years. A major incursion of CBPP was reported from illegally smuggled Raya Azebo type cattle from Ethiopia, introduced through the Southern Red Sea administrative region of Eritrea (the Afar area bordering Ethiopia). The first case was detected in the Asmara abattoir during post mortem inspection. Characteristic CBPP clinical signs and post-mortem lesions were observed in affected herd during the outbreak of the disease. Significant number of in-contact indigenous cattle was infected by the disease. Samples were first sent to OIE reference laboratory CIRADEMVT in France for confirmation. The disease was confirmed by PCR on 15 January 2003.Samples of Pleural fluids and lung tissues were collected from CBPP infected animals and tested using the polymerase chain reaction (PCR) technique at the National Veterinary Laboratory. The affected cattle herds were held in an isolation pen and eventually destroyed following confirmation of the disease. Following this incident, surveillance of CBPP was stepped-up and a total of 4,695 serum samples were collected from 313 sampling units or villages and submitted to the National Veterinary Laboratory for testing in 2004 one year after the outbreak of the disease as part of the epidemiosurveillance. Serum samples collected for sero-surveillance were tested for CBPP antibodies by the use of the monoclonal antibody specific for Mycoplasma mycoides subspecies mycoides sc as described in the competitive ELISA kit manual from CIRAD-EMVT, France. During this post outbreak sero-surveillance sampling season, all age group animals were eligible for sampling. Out of the total sampled animals 67 (1.43%) were positive for Mycoplasma mycoides subsp. mycoides sc antibodies using the cELISA test. This result suggested that very low lateral infectious agent transmission could have taken place. Vaccination as a control measure had never

    Tropical peatland in Southeast Asia is a vast reservoir of terrestrial carbon, which covers 24.8 million hectares and stores 68.5 PgC peat, equal to 11-14% of global peat carbon. In recent decades, large scale peatland fire has occurred frequently in that region, in which many areas of peatland were reclaimed with intention to use the land for forest plantation and rice paddy. We conducted a plot-scale peat burning experiment to elucidate the characteristics of gaseous carbon emission from a tropical peatland fire at the ground level. The experimental site was established at an open area 20 km southeast from Palangka Raya, Central Kalimantan Province, Indonesia. The size of the burning plot is 4 m in length and 3 m in width. Gas samples were collected at heights of 1.0, 0.5, 0.0 (aboveground), -0.1 and -0.2 m (belowground) through stainless steel and/or aluminum tubes settled across the edge of the plot. The concentrations of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4) and particulate matter (PM) was determined. Soil temperature was recorded every 10 minutes 0.1 and 0.2 m below the ground surface. Twelve iron rods were installed in 1-m by 1-m square grid to determine the depth of burn scar. After ignition, flaming stage of peat burning was ceased within 1-2 hours. The following smoldering stage continued for a week. In the flaming stage, soil temperature at -0.1 m increased tentatively. After the smoldering stage began, the temperature rapidly increased to 350-450°C. Response of soil temperature at -0.2 m was less prominent. Concentrations of gaseous components became maximal in the flaming stage. During the smoldering stage, the concentrations gradually decreased. The influence of burning on CO2 and PM was prominently remained at -0.1 m, whereas those at -0.2 m were not so much. The averaged burnt depth was 5.8±5.1 cm. Based on bulk density of 0.22 g/cm3 and carbon content of 55.5%, the amount of carbon lost from the plot was 85.3 kg. Most of the

    The project BIOCLOUDS aimed at investigating and quantifying the role of bioaerosols in tropospheric clouds. We focused on the studies on microorganisms, mainly bacteria. To reach our objective we (1) isolated and identified INA bacterial strains in cloud waters, (2) studied in more details IN properties of bacteria isolated from cloud waters in laboratories and cloud chamber, (3) used new data as input to cloud models. 1. Isolation and Identification of INA bacterial strains in cloud waters Cloud water samples were collected at the puy de Dôme station under sterile conditions, microorganisms were cultured on agar plates and further identified by DNA sequencing coding for16SrRNA. 257 bacterial strains isolated from 25 cloud events were screened and 44 isolates were selected as they belonged to Pseudomonas, Xanthomonas and Erwinia genera which are potential INA candidates. Using the classical "Droplet Freezing method" as ice nucleation test, 7 strains were shown INA+. Their cumulative IN frequency profiles were established and showed that some of them are very efficient, for example the strain Pseudomonas syringae 13b74 started to nucleate a t-3°C and 4% of the cells were active at- 5°C. 2. Further laboratory investigations of IN properties of cloud bacterial strains All the experiments presented in this section were carried out with 3 Pseudomonas syringae strains. We tested the influence of O3, NO, UV and pH, which are atmospheric markers of anthropogenic activity, on the IN activity of the Pseudomonas strains. It was clearly shown that pH had a main influence, acidic pHs decreased the IN activity of the strains. This suggests a negative impact of human emissions on the natural capacity of bacteria to precipitate with rain. The 3 Pseudomas strains were sprayed in the AIDA cloud chamber. The survival of these strains with time before cloud formation was measured and will be used in the future to parameterize models for bacterial transport. After cloud formation

    Reliable assessment of islet viability, mass, and purity must be met prior to transplanting an islet preparation into patients with type 1 diabetes. The standard method for quantifying human islet preparations is by direct microscopic analysis of dithizone-stained islet samples, but this technique may be susceptible to inter-/intraobserver variability, which may induce false positive/negative islet counts. Here we describe a simple, reliable, automated digital image analysis (ADIA) technique for accurately quantifying islets into total islet number, islet equivalent number (IEQ), and islet purity before islet transplantation. Islets were isolated and purified from n = 42 human pancreata according to the automated method of Ricordi et al. For each preparation, three islet samples were stained with dithizone and expressed as IEQ number. Islets were analyzed manually by microscopy or automatically quantified using Nikon's inverted Eclipse Ti microscope with built-in NIS-Elements Advanced Research (AR) software. The AIDA method significantly enhanced the number of islet preparations eligible for engraftment compared to the standard manual method (p methods showed good correlations between mean values of IEQ number (r(2) = 0.91) and total islet number (r(2) = 0.88) and thus increased to r(2) = 0.93 when islet surface area was estimated comparatively with IEQ number. The ADIA method showed very high intraobserver reproducibility compared to the standard manual method (p method versus the ADIA method (p method also detected small islets between 10 and 50 µm in size. Automated digital image analysis utilizing the Nikon Instruments software is an unbiased, simple, and reliable teaching tool to comprehensively assess the individual size of each islet cell preparation prior to transplantation. Implementation of this technology to improve engraftment may help to advance the therapeutic efficacy and accessibility of islet transplantation across centers. PMID:23683575

    Full Text Available The residence time of bacterial cells in the atmosphere is predictable by numerical models. However, estimations of their aerial dispersion as living entities are limited by lacks of information concerning survival rates and behavior in relation to atmospheric water. Here we investigate the viability and ice nucleation (IN activity of typical atmospheric ice nucleation active bacteria (Pseudomonas syringae and P. fluorescens when airborne in a cloud simulation chamber (AIDA, Karlsruhe, Germany. Cell suspensions were sprayed into the chamber and aerosol samples were collected by impingement at designated times over a total duration of up to 18 h, and at some occasions after dissipation of a cloud formed by depressurization. Aerosol concentration was monitored simultaneously by online instruments. The cultivability of airborne cells decreased exponentially over time with a half-life time of 250 ± 30 min (about 3.5 to 4.5 h. In contrast, IN activity remained unchanged for several hours after aerosolization, demonstrating that IN activity was maintained after cell death. Interestingly, the relative abundance of IN active cells still airborne in the chamber was strongly decreased after cloud formation and dissipation. This illustrates the preferential precipitation of IN active cells by wet processes. Our results indicate that from 106 = cells aerosolized from a surface, one would survive the average duration of its atmospheric journey estimated at 3.4 days. Statistically, this corresponds to the emission of 1 cell that achieves dissemination every ~33 min per m2 of cultivated crops fields, a strong source of airborne bacteria. Based on the observed survival rates, depending on wind speed, the trajectory endpoint could be situated several hundreds to thousands of kilometers from the emission source. These results should improve the representation of the aerial dissemination of bacteria in numeric models.

    The current study reports the clinical features and treatment outcome of 67 patients with acute promyelocytic leukemia (APL presented to National Cancer Institute (NCI-Cairo, in Egypt from January 2007 to January 2011. The median follow-up time was 36 months. All patients were treated with the simultaneous administration of all-trans retinoic acid (ATRA and anthracyclin. The treatment protocol was modified due to resource limitations at the NCI-Cairo by replacing of idarubicin with doxorubicin in most of the cases and the inclusion of cytarbine during the consolidation phase only in pediatric patients. All patients who achieved molecular complete remission (CRm after consolidation received two-year maintenance treatment with low dose chemotherapy composed of 6 mercaptopurine, methotrexate and intermittent ATRA courses. The median age at presentation was 29 years. There was a slight male predominance (53%.  Bleeding was the most common presenting symptom (79%. Most patients had an intermediate risk Sanz score (49% and 34% had a high risk score.  All patients achieved molecular CR at end of consolidation therapy with a median duration of 100 days. The main therapeutic complications during the induction phase were febrile neutropenia (42%, bleeding (18% and differentiation syndrome (11%. Five patients died at diagnosis due to bleeding, three died during induction chemotherapy due to febrile neutropenia (n=2 and bleeding (n=1 and one patient died during consolidation therapy due to febrile neutropenia.  The 3-year OS was 89% and relapse rate was 3%. Adapting standard AIDA treatment protocols to limited resources by reducing dose-intensity during treatment consolidation, using ATRA in the consolidation phase and alternative anthracyclin (doxorubicin may be a valid treatment option in developing countries. In spite of the increased incidence of high and intermediate risk score APL in our sample, we reported an acceptable CR rate

Studies captured by the search strategy were screened by two reviewers and included if the focus was on barriers and facilitators of e-health technology adoption by physicians.Results: Full-text screening yielded 74 studies to be included in the scoping review. Within those studies, eleven themes were identified, including cost and liability issues, unwillingness to use e-health technology, and training and support.Conclusion: Cost and liability issues, unwillingness to use e-health technology, and training and support were the most frequently mentioned barriers and facilitators to the adoption of e-health technology. Government-level payment incentives and privacy laws to protect health information may be the key to overcome cost and liability issues. The adoption of e-health technology may be facilitated by tailoring to the individual physician’s knowledge of the e-health technology and the use of follow-up sessions for physicians and on-site experts to support their use of the e-health technology. To ensure the effective uptake of e-health technologies, physician perspectives need to be considered in creating an environment that enables the adoption of e-health strategies.

  4. Acute promyelocytic leukemia, study of predictive factors for Differentiation Syndrome, single center experience

    International Nuclear Information System (INIS)

    Reports about patients with acute promyelocytic leukemia from the Middle East are few; in this study we are reporting our single center experience of treating 29 patients over 6 years. Acute promyelocytic leukemia treatment response is markedly improved after the introduction of ATRA. Treatment related complication is still an important issue particularly Differentiation Syndrome. Prediction to its occurrence has been tried by other groups. We aimed to study all the possible predictive factors of acute promyelocytic leukemia. Our chemotherapy induction protocol is AIDA protocol which includes ATRA 45 mg/m2/d in divided doses every 12h, and Idarubicin 12 mg/ m2/d IV on days 3, 5, 7, and 9. Differentiation Syndrome occurred in 48.3% of patients and was mainly presented by pulmonary symptoms in 55.2%, 6 cases died during induction. None of the predictive factors studied showed a statistically significant difference between patients who developed Differentiation Syndrome and those who did not. Differentiation Syndrome did not affect overall survival. Cox regression showed an inverse yet a non significant association between PET- HEMA and overall survival probability (P = 0.168). In conclusion, Differentiation Syndrome has no clear predictive factor to date. The best approach is to hold ATRA and give dexamethasone which is quite effective as reported in the literature. PETHEMA risk model has a moderately significant prognostic value look for all possible predictive factors of Differentiation syndrome (DS) which were first described in 1992 by frankel et al. (4) and represented the major complication through this disease course: studies had reported conflicting results about this (5,6). In addition we will compare our data to other areas of the world

  5. Stable Orbits in the Didymos Binary Asteroid System - Useful Platforms for Exploration

    We have analyzed particle motion in binary asteroid systems to search for stable orbits. In particular, we studied the motion of particles near the asteroid 1996 GT (Didymos), proposed as a target for the AIDA mission. The combined gravity fields of the odd-shaped rotating objects moving about each other are complex. In addition, orbiting spacecraft or dust particles are affected by radiation pressure, possibly exceeding the faint gravitational forces. For the numerical integrations, we adopt parameters for size, shape, and rotation from telescopic observations. To simulate the effect of radiation pressure during a spacecraft mission, we apply a spacecraft wing-box shape model. Integrations were carried out beginning in near-circular orbits over 11 days, during which the motion of the particles were examined. Most orbits are unstable with particles escaping quickly or colliding with the asteroid bodies. However, with carefully chosen initial positions, we found stable motion (in the orbiting plane of the secondary) associated with the Lagrangian points (L4 and L5), in addition to horseshoe orbits, where particles move from one of the Lagrangian point to the other. Finally, we examined orbits in 1:2 resonances with the motion of the orbital period of the secondary. Stable conditions depend strongly on season caused by the inclination of the mutual orbit plane with respect to Didymos solar orbit. At larger distance from the asteroid pair, we find the well-known terminator orbits where gravitational attraction is balanced against radiation pressure. Stable orbits and long motion arcs are useful for long tracking runs by radio or Laser instruments and are well-suited for modelling of the ephemerides of the asteroid pair and gravity field mapping. Furthermore, these orbits may be useful as observing posts or as platforms for approach. These orbits may also represent traps for dust particles, an opportunity for dust collection - or possibly a hazard to spacecraft

    This study reports on the origin of small-scale ice crystal complexity and its influence on the angular light scattering properties of cirrus clouds. Cloud simulation experiments were conducted at the AIDA (Aerosol Interactions and Dynamics in the Atmosphere) cloud chamber of the Karlsruhe Institute of Technology (KIT). A new experimental procedure was applied to grow and sublimate ice particles at defined super- and subsaturated ice conditions and for temperatures in the -40 to -60 °C range. The experiments were performed for ice clouds generated via homogeneous and heterogeneous initial nucleation. Small-scale ice crystal complexity was deduced from measurements of spatially resolved single particle light scattering patterns by the latest version of the Small Ice Detector (SID-3). It was found that a high crystal complexity dominates the microphysics of the simulated clouds and the degree of this complexity is dependent on the available water vapor during the crystal growth. Indications were found that the small-scale crystal complexity is influenced by unfrozen H2SO4 / H2O residuals in the case of homogeneous initial ice nucleation. Angular light scattering functions of the simulated ice clouds were measured by the two currently available airborne polar nephelometers: the polar nephelometer (PN) probe of Laboratoire de Métérologie et Physique (LaMP) and the Particle Habit Imaging and Polar Scattering (PHIPS-HALO) probe of KIT. The measured scattering functions are featureless and flat in the side and backward scattering directions. It was found that these functions have a rather low sensitivity to the small-scale crystal complexity for ice clouds that were grown under typical atmospheric conditions. These results have implications for the microphysical properties of cirrus clouds and for the radiative transfer through these clouds.

    We have designed the BIO-IN detector as part of the ice nucleus counter FINCH (Fast Ice Nuclei CHamber counter) to distinguish activated Ice Nuclei (IN) ice crystals from water droplets (CCN) (Bundke et al. 2008) and their fraction of biological origin (Bundke 2010). The modified BIO-IN sensor illuminates an aerosol stream with a 405 nm laser, replacing a 365nm LED of the original BIO IN design. Particles will scatter the light and those of biological origin will show intrinsic fluorescence emissions by excitation of mainly Riboflavin, also known as vitamin B2. The incident laser light is circularly polarized by introducing a quarter-wave-plate. The circular depolarization ratio (p44/p11) of the scattering matrix is measured in the backward direction by two photomultipliers at 110° scattering angle using a combination of quarter-wave-plate and a beam splitting cube to analyze the two circular polarization components. The detection limit was lowered towards particle size of about 400nm diameter (non activated particles). It is now possible to calculate the activated fraction of IN of biological origin with respect to all biological particles measured with one detector. The performance of the sensor will be demonstrated showing the circular- depolarization properties of different test aerosol, dust samples, volcanic ashes as well as different biological particles. Measurements on the mountain Puy de Dôme of IN number concentration of ambient air, as well as measurements at the AIDA facility in Karlsruhe of the IN activation curves from different bacteria are shown.

    Full Text Available Aim: To estimate the incidence of VTE in Indonesian patients undergoing major orthopedic surgery and not receiving thromboprophylaxis.Methods: This was an open clinical study of consecutive Indonesian patients undergoing major orthopedic surgery, conducted in 3 centers in Jakarta. Bilateral venography was performed between days 5 and 8 after surgery to detect the asymptomatic and to confi rm the symptomatic VTE. These patients were followed up to one month after surgery.Results: A total of 17 eligible patients were studied, which a median age of 69 years and 76.5% were females. Sixteen out of the 17 patients (94.1% underwent hip fracture surgery (HFS. The median time from injury to surgery was 23 days (range 2 to 197 days, the median duration of surgery was 90 minutes (range 60 to 255 minutes, and the median duration of immobilization was 3 days (range 1 to 44 days. Thirteen out of the 17 patients were willing to undergo contrast venography. A symptomatic VTE was found in 9 patients (69.2% at hospital discharge. Symptomatic VTE was found in 3 patients (23.1%, all corresponding to clinical signs of DVT and none with clinical sign of PE. These patients were treated initially with a low molecular weight heparin, followed by warfarin. Sudden death did not occur up to hospital discharge. From hospital discharge until 1-month follow-up, there were no additional cases of symptomatic VTE. No sudden death, bleeding complication, nor re-hospitalization was found in the present study.Conclusion: The incidence of asymptomatic (69.2% and symptomatic (23.1% VTE after major orthopedic surgery without thromboprophylaxis in Indonesian patients (SMART and AIDA, and still higher than the results of the Western studies. A larger study is required to establish the true incidence, and more importantly, that the use of thromboprophylaxis in these patients is warranted.

    Full Text Available The hygroscopic growth and droplet activation of uncoated soot particles and such coated with succinic acid and sulfuric acid were investigated during the IN-11 campaign at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA facility. A GFG-1000 soot generator applying nitrogen, respectively argon as carrier gas and a miniCAST soot generator were utilized to generate soot particles. Different organic carbon (OC to black carbon (BC ratios were adjusted for the CAST-soot by varying the fuel to air ratio. The hygroscopic growth was investigated by means of the mobile Leipzig Aerosol Cloud Interaction Simulator (LACIS-mobile and two different Hygroscopicity Tandem Differential Mobility Analyzers (HTDMA, VHTDMA. Two Cloud Condensation Nucleus Counter (CCNC were applied to measure the activation of the particles. For the untreated soot particles neither hygroscopic growth nor activation was observed, with exception of a partial activation of GFG-soot generated with argon as carrier gas. Coatings of succinic acid lead to a detectable hygroscopic growth of GFG-soot and enhanced the activated fraction of GFG- (carrier gas: argon and CAST-soot, whereas no hygroscopic growth of the coated CAST-soot was found. Sulfuric acid coatings lead to an OC-content dependent hygroscopic growth of CAST-soot. Such a dependence was not observed for activation measurements. Coating with sulfuric acid decreased the amount of Polycyclic Aromatic Hydrocarbons (PAH, which were detected by AMS-measurements in the CAST-soot, and increased the amount of substances with lower molecular weight than the initial PAHs. We assume, that these reaction products increased the hygroscopicity of the coated particles in addition to the coating substance itself.

  12. Use of milk progesterone RIA for the monitoring of artificial insemination of dairy cows on smallholder farms in Turkey

    International Nuclear Information System (INIS)

    Full text: The technique of artificial insemination (AI) has been widely used in Turkey for several years to improve dairy cattle productivity. The fertility rate resulting from this technique is still low. The objective of this study was to identify causes of artificial insemination inefficiency on smallholder farms in Turkey. The radioimmunoassay (RIA) for progesterone in milk samples collected from dairy cows on smallholder farms have been used for monitoring ovarian activity, diagnosis of pregnancy and non-pregnancy, assessment of the accuracy of oestrus detection and for surveying efficiency of artificial insemination services. All raw data were stored and analysed by the computer program AIDA (Artificial Insemination Database Application). Milk samples were collected on day 0, days 10-12, and days 22-24 after artificial insemination from 220 dairy cows in 10 different regions. Based on the progesterone concentration in three milk samples, the reproductive status of the cows could be identified. Conception rate at first service was 63.0% and overall conception rate was 70.4 %. The mean interval from calving to first service was 85.4 days and the mean interval from calving to conception was 96.1 days. The progesterone concentration on the day of AI was negatively related to conception (P<0.001) and also associated with season. Incidence of incorrect artificial insemination, most likely due to erroneous heat detection, was 11.5%. The results show that important factors affecting reproductive performance of dairy cows on smallholder farms include nutritional management, oestrus detection and season. The quality and efficiency of AI on smallholder dairy cows should be improved by using progesterone RIA. (author)

    Full Text Available Aida InbalThrombosis and Hemostasis Unit, Hematology Institute, Beilinson Hospital, Rabin Medical Center, Petach Tikva, and Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, IsraelAbstract: Factor XIII (FXIII is a protransglutaminase composed of two catalytic A subunits and two carrier B subunits. An intracellular form of FXIII is present in monocytes/macrophages and platelets as a homodimer of two A subunits. Following activation by thrombin, FXIII becomes plasma transglutaminase, which crosslinks γ-glutamyl-ε-lysine residues of fibrin chains and thereby stabilizes the fibrin clot. FXIII deficiency results in a moderate to severe hemorrhagic disorder, abnormal wound healing in about 30% of patients, and recurrent abortion in homozygous females. More than 800 cases of FXIII deficiency have been reported, most of them due to mutation in the FXIII-A gene, resulting in FXIII-A deficiency. Among mutations causing FXIII-A deficiency, 50% are missense mutations. Only 16 mutations in the FXIII-B gene have been published. Routine laboratory tests are normal in patients with FXIII deficiency, and the diagnosis is established by demonstration of decreased FXIII activity and antigen. Plasma-derived, virus-inactivated factor XIII concentrate is the treatment of choice. The low plasma levels of FXIII (about 5% required to control bleeding and its long half-life make monthly prophylactic therapy feasible. Recently, recombinant FXIII concentrate with a half-life similar to that of native FXIII has been developed and tested in a multinational clinical study. This new product appears to be safe and appropriate for lifelong prophylactic treatment of patients with FXIII-A deficiency.Keywords: recombinant FXIII concentrate, FXIII deficiency

    Full Text Available In this paper, the effect of the morphological modification of aerosol particles with respect to heterogeneous ice nucleation is comprehensively investigated for laboratory-generated hematite particles as a model substrate for atmospheric dust particles. The surface area-scaled ice nucleation efficiencies of monodisperse cubic hematite particles and milled hematite particles were measured with a series of expansion cooling experiments using the Aerosol Interaction and Dynamics in the Atmosphere (AIDA cloud simulation chamber. Complementary off-line characterization of physico-chemical properties of both hematite subsets were also carried out with scanning electron microscopy (SEM, energy dispersive X-ray (EDX spectroscopy, dynamic light scattering (DLS, and an electro-kinetic particle charge detector to further constrain droplet-freezing measurements of hematite particles. Additionally, an empirical parameterization derived from our laboratory measurements was implemented in the single-column version of the Community Atmospheric Model version 5 (CAM5 to investigate the model sensitivity in simulated ice crystal number concentration on different ice nucleation efficiencies. From an experimental perspective, our results show that the immersion mode ice nucleation efficiency of milled hematite particles is almost an order of magnitude higher at −35.2 °C T < −33.5 °C than that of the cubic hematite particles, indicating a substantial effect of morphological irregularities on immersion mode freezing. Our modeling results similarly show that the increased droplet-freezing rates of milled hematite particles lead to about one order magnitude higher ice crystal number in the upper troposphere than cubic hematite particles. Overall, our results suggest that the surface irregularities and associated active sites lead to greater ice activation through droplet-freezing.

  15. Efficiency of the deposition mode ice nucleation on mineral dust particles

    Full Text Available The deposition mode ice nucleation efficiency of various dust aerosols was investigated at cirrus cloud temperatures between 196 K and 223 K using the aerosol chamber facility AIDA (Aerosol Interaction and Dynamics in the Atmosphere. Arizona test dust (ATD as a reference material and two dust samples from the Takla Makan desert in Asia (AD1 and Sahara (SD2 were used for the experiments at simulated cloud conditions. The dust particle sizes were almost lognormally distributed with mode diameters between 0.3 µm and 0.5 µm and geometric standard deviations between 1.6 and 1.9. Deposition ice nucleation was most efficient on ATD particles with ice-active particle fractions of about 0.6 and 0.8 at an ice saturation ratio Si<1.15 and temperatures of 223 K and 209 K, respectively. No significant change of the ice nucleation efficiency was found in up to three subsequent cycles of ice activation and evaporation with the same ATD aerosol. The desert dust samples SD2 and AD1 showed a significantly lower fraction of active deposition nuclei, about 0.25 at 223 K and Si<1.35. For all samples the ice activated aerosol fraction could be approximated by an exponential equation as function of Si. This formulation of ice activation spectra may be used to calculate the formation rate of ice crystals in models, if the number concentration of dust particles is known. More experimental work is needed to quantify the variability of the ice activation spectra as function of the temperature and dust particle properties.

    In the past decades air traffic has been substantially growing affecting air quality and climate. According to the International Civil Aviation Authority (ICAO), in the next few years world passenger and freight traffic is expected to increase annually by 6-7% and 4-5%, respectively. One possibility to reduce aviation impacts on the atmosphere and climate might be the replacement of fossil fuels by alternative fuels. However, so far the effects of alternative fuels on particle emissions from aircraft engines and their ability to form contrails remain uncertain. To study the effects of alternative fuels on particle emissions and the formation of contrails, the Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS) field experiment was conducted in California. In May 2014, the DLR Falcon 20 and the NASA HU-25 jet aircraft were instrumented with an extended aerosol and trace gas payload probing different types of fuels including JP-8 and JP-8 blended with HEFA (Hydroprocessed Esters and Fatty Acids) while the NASA DC8 aircraft acted as the source aircraft for ACCESS-2. Emission measurements were taken in the DC8 exhaust plumes at aircraft cruise level between 9-12 km altitude and at distances between 50 m and 20 km behind the DC8 engines. Here, we will present results from the ACCESS-2 aerosol measurements which show a 30-60% reduction of the non-volatile (mainly black carbon) particle number concentration in the aircraft exhaust for the HEFA-blend compared to conventional JP-8 fuel. Size-resolved particle emission indices show the largest reductions for larger particle sizes suggesting that the HEFA blend contains fewer and smaller black carbon particles. We will combine the airborne measurements with a parameterization of deposition nucleation developed during a number of ice nucleation experiments at the AIDA chamber in Karlsruhe and discuss the impact of alternative fuels on the abundance of potential ice nuclei at cruise conditions.

    Members of the Burkholderia cepacia complex (Bcc) are important in medical, biotechnological, and agricultural disciplines. These bacteria naturally occur in soil and water environments and have adapted to survive in association with plants and animals including humans. All Bcc species are opportunistic pathogens including Burkholderia cenocepacia that causes infections in cystic fibrosis and chronic granulomatous disease patients. The adaptation of B. cenocepacia to the host environment was assessed in a rat chronic respiratory infection model and compared to that of high cell-density in vitro grown cultures using transcriptomics. The distribution of genes differentially expressed on chromosomes 1, 2, and 3 was relatively proportional to the size of each genomic element, whereas the proportion of plasmid-encoded genes differentially expressed was much higher relative to its size and most genes were induced in vivo. The majority of genes encoding known virulence factors, components of types II and III secretion systems and chromosome 2-encoded type IV secretion system were similarly expressed between in vitro and in vivo environments. Lower expression in vivo was detected for genes encoding N-acyl-homoserine lactone synthase CepI, orphan LuxR homolog CepR2, zinc metalloproteases ZmpA and ZmpB, LysR-type transcriptional regulator ShvR, nematocidal protein AidA, and genes associated with flagellar motility, Flp type pilus formation, and type VI secretion. Plasmid-encoded type IV secretion genes were markedly induced in vivo. Additional genes induced in vivo included genes predicted to be involved in osmotic stress adaptation or intracellular survival, metal ion, and nutrient transport, as well as those encoding outer membrane proteins. Genes identified in this study are potentially important for virulence during host–pathogen interactions and may be associated with survival and adaptation to the host environment during chronic lung infections.

    Here, we report the case of an acute promyelocytic leukemia (APL) patient who-although negative for FLT3 mutations at diagnosis-developed isolated FLT3 tyrosine kinase II domain (FLT3-TKD)-positive meningeal relapse, which, in retrospect, could be traced back to a minute bone marrow subclone present at first diagnosis. Initially, the 48-yr-old female diagnosed with high-risk APL had achieved complete molecular remission after standard treatment with all-trans retinoic acid (ATRA) and chemotherapy according to the AIDA (ATRA plus idarubicin) protocol. Thirteen months after the start of ATRA maintenance, the patient suffered clinically overt meningeal relapse along with minute molecular traces of PML/RARA (promyelocytic leukemia/retinoic acid receptor alpha) in the bone marrow. Following treatment with arsenic trioxide and ATRA in combination with intrathecal cytarabine and methotrexate, the patient achieved a complete molecular remission in both cerebrospinal fluid (CSF) and bone marrow, which currently lasts for 2 yr after completion of therapy. Whole-exome sequencing and subsequent ultradeep targeted resequencing revealed a heterozygous FLT3-TKD mutation in CSF leukemic cells (p.D835Y, c.2503G>T, 1000/1961 reads [51%]), which was undetectable in the concurrent bone marrow sample. Interestingly, the FLT3-TKD mutated meningeal clone originated from a small bone marrow subclone present in a variant allele frequency of 0.4% (6/1553 reads) at initial diagnosis. This case highlights the concept of clonal evolution with a subclone harboring an additional mutation being selected as the "fittest" and leading to meningeal relapse. It also further supports earlier suggestions that FLT3 mutations may play a role for migration and clonal expansion in the CSF sanctuary site. PMID:27626069

    Full Text Available The current study reports the clinical features and treatment outcome of 67 patients with acute promyelocytic leukemia (APL presented to National Cancer Institute (NCI-Cairo, in Egypt from January 2007 to January 2011. The median follow-up time was 36 months. All patients were treated with the simultaneous administration of all-trans retinoic acid (ATRA and anthracyclin. The treatment protocol was modified due to resource limitations at the NCI-Cairo by replacing of idarubicin with doxorubicin in most of the cases and the inclusion of cytarbine during the consolidation phase only in pediatric patients. All patients who achieved molecular complete remission (CRm after consolidation received two-year maintenance treatment with low dose chemotherapy composed of 6 mercaptopurine, methotrexate and intermittent ATRA courses. The median age at presentation was 29 years. There was a slight male predominance (53%.  Bleeding was the most common presenting symptom (79%. Most patients had an intermediate risk Sanz score (49% and 34% had a high risk score.  All patients achieved molecular CR at end of consolidation therapy with a median duration of 100 days. The main therapeutic complications during the induction phase were febrile neutropenia (42%, bleeding (18% and differentiation syndrome (11%. Five patients died at diagnosis due to bleeding, three died during induction chemotherapy due to febrile neutropenia (n=2 and bleeding (n=1 and one patient died during consolidation therapy due to febrile neutropenia.  The 3-year OS was 89% and relapse rate was 3%. Adapting standard AIDA treatment protocols to limited resources by reducing dose-intensity during treatment consolidation, using ATRA in the consolidation phase and alternative anthracyclin (doxorubicin may be a valid treatment option in developing countries. In spite of the increased incidence of high and intermediate risk score APL in our sample, we reported an acceptable CR rate, toxicity and OS.

  20. First correlated measurements of the shape and light scattering properties of cloud particles using the new Particle Habit Imaging and Polar Scattering (PHIPS probe

    Full Text Available Studying the radiative impact of cirrus clouds requires knowledge of the relationship between their microphysics and the single scattering properties of cloud particles. Usually, this relationship is obtained by modeling the optical scattering properties from in situ measurements of ice crystal size distributions. The measured size distribution and the assumed particle shape might be erroneous in case of non-spherical ice particles. We present here a novel optical sensor (the Particle Habit Imaging and Polar Scattering probe, PHIPS designed to measure simultaneously the 3-D morphology and the corresponding optical and microphysical parameters of individual cloud particles. Clouds containing particles ranging from a few micrometers to about 800 μm diameter in size can be characterized systematically with an optical resolution power of 2 μm and polar scattering resolution of 1° for forward scattering directions (from 1° to 10° and 8° for side and backscattering directions (from 18° to 170°. The maximum acquisition rates for scattering phase functions and images are 262 KHz and 10 Hz, respectively. Some preliminary results collected in two ice cloud campaigns conducted in the AIDA cloud simulation chamber are presented. PHIPS showed reliability in operation and produced size distributions and images comparable to those given by other certified cloud particles instruments. A 3-D model of a hexagonal ice plate is constructed and the corresponding scattering phase function is compared to that modeled using the Ray Tracing with Diffraction on Facets (RTDF program. PHIPS is a highly promising novel airborne optical sensor for studying the radiative impact of cirrus clouds and correlating the particle habit-scattering properties which will serve as a reference for other single, or multi-independent, measurement instruments.
