    2008-01-01

    In this introductory article we attempt to provide the theoretical basis for developing the interaction between X-rays and matter, so that one can unravel properties of matter by interpretation of X-ray experiments on samples. We emphasize that we are dealing with the basics, which means that we...... shall limit ourselves to a discussion of the interaction of an X-ray photon with an isolated atom, or rather with a single electron in a Hartree-Fock atom. Subsequent articles in this issue deal with more complicated - and interesting - forms of matter encompassing many atoms or molecules. To cite...... this article: J. Als-Nielsen, C. R.

    his paper provides an introduction to interactive information retrieval--the study of human interaction with information retrieval systems. Interactive information retrieval may be contrasted with the "system-centered" view of information retrieval in which changes to information retrieval system variables are manipulated in isolation from users in laboratory situations. The paper elucidates current models of interactive information retrieval, namely, the episodic model, the stratif...

    This paper investigates the interaction between transient wave and non-stationary and non-conservative basic flow.An interaction equation is derived from the zonally symmetric and non-hydrostatic primitive equations in Cartesian coordinates by using the Momentum-Casimir method. In the derivation, it is assumed that the transient disturbances satisfy the linear perturbation equations and the basic states are non-conservative and slowly vary in time and space.The diabatic heating composed of basic-state heating and perturbation heating is also introduced. Since the theory of wave-flow interaction is constructed in non-hydrostatic and ageostrophic dynamical framework, it is applicable to diagnosing the interaction between the meso-scale convective system in front and the background flow.It follows from the local interaction equation that the local tendency of pseudomomentum wave-activity density depends on the combination of the perturbation flux divergence second-order in disturbance amplitude, the local change of basic-state pseudomomentum density, the basic-state flux divergence and the forcing effect of diabatic heating. Furthermore, the tendency of pseudomomentum wave-activity density is opposite to that of basic-state pseudomomentum density.The globally integrated basic-state pseudomomentum equation and wave-activity equation reveal that the global development of basic-state pseudomomentum is only dominated by the basic-state diabatic heating while it is the forcing effect of total diabatic heating from which the global evolution of pseudomomentum wave activity results.Therefore, the interaction between the transient wave and the non-stationary and non-conservative basic flow is realized in virtue of the basic-state diabatic heating.

  7. Synergistic interactions of lipids and myelin basic protein

    This report describes force measurements and atomic force microscope imaging of lipid-protein interactions that determine the structure of a model membrane system that closely mimics the myelin sheath. Our results suggest that noncovalent, mainly electrostatic and hydrophobic, interactions are responsible for the multilamellar structure and stability of myelin. We find that myelin basic protein acts as a lipid coupler between two apposed bilayers and as a lipid "hole-filler," effectively preventing defect holes from developing. From our protein-mediated-adhesion and force-distance measurements, we develop a simple quantitative model that gives a reasonably accurate picture of the molecular mechanism and adhesion of bilayer-bridging proteins by means of noncovalent interactions. The results and model indicate that optimum myelin adhesion and stability depend on the difference between, rather than the product of, the opposite charges on the lipid bilayers and myelin basic protein, as well as on the repulsive forces associated with membrane fluidity, and that small changes in any of these parameters away from the synergistically optimum values can lead to large changes in the adhesion or even its total elimination. Our results also show that the often-asked question of which membrane species, the lipids or the proteins, are the "important ones" may be misplaced. Both components work synergistically to provide the adhesion and overall structure. A better appreciation of the mechanism of this synergy may allow for a better understanding of stacked and especially myelin membrane structures and may lead to better treatments for demyelinating diseases such as multiple sclerosis. lipid-protein interactions | myelin membrane structure | membrane adhesion | membrane regeneration/healing | demyelinating diseases

  8. Spectroscopic Electrochemical Studies of Interaction Between Fuchsin Basic DNA

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Visible spectroscopic and electrochemical methods were used to study the interactions between DNA and fuchsin basic(FB). FB has an irreversible electro-oxidation peak in 5 mmol/L Tris-HCl buffer solution at pH = 7.4 on a glassy carbon electrode(GCE). After adding certain concentration of dsDNA, the oxidation peak current of FB decreases, but the peak potential hardly changs. The visible absorption spectroscopic study shows that the binding mode of FB to dsDNA is intercalative binding and electrostatic binding when the ratio of the concentration of dsDNA to FB is smaller than 0. 2, and a new substance, which produces a new absorption peak, is obtained via a covalent binding between dsDNA and FB apart from intercalative binding and electrostatic binding when the ratio of the concentration of dsDNA to FB is larger than 0. 2. The visible absorption spectra varies no longer when the ratio of the concentration of dsDNA to FB is larger than 1.5. A mean binding ratio of dsDNA to FB was determined to be 1.4: 1,suggesting that two complexes FB-dsDNA and FB-2dsDNA be formed. The interaction between FB and ssDNA was only electrostatic binding. The more powerful interaction of FB with dsDNA than with ssDNA may be applied for the recognition of dsDNA and ssDNA, and in DNA biosensor as hybridization indicator.

    The Ino4 protein belongs to the basic helix–loop–helix (bHLH) family of proteins. It is known to form a dimer with Ino2p, which regulates phospholipid biosynthetic genes. Mammalian bHLH proteins have been shown to form multiple dimer combinations. However, this flexibility in dimerization had not been documented for yeast bHLH proteins. Using the yeast two-hybrid assay and a biochemical assay we show that Ino4p dimerizes with the Pho4p, Rtg1p, Rtg3p and Sgc1p bHLH proteins. Screening a yeast ...

    2006-01-01

    The skin exerts a number of essential protective functions ensuring homeostasis of the whole body. In the present review barrier function of the skin, thermoregulation, antimicrobial defence and the skin-associated immune system are discussed. Barrier function is provided by the dynamic stratum corneum structure composed of lipids and corneocytes. The stratum corneum is a conditio sine qua non for terrestrial life. Impairment of barrier function can be due to injury and inflammatory skin diseases. Textiles, in particular clothing, interact with skin functions in a dynamic pattern. Mechanical properties like roughness of fabric surface are responsible for non-specific skin reactions like wool intolerance or keratosis follicularis. Thermoregulation, which is mediated by local blood flow and evaporation of sweat, is an important subject for textile-skin interactions. There are age-, gender- and activity-related differences in thermoregulation of skin that should be considered for the development of specifically designed fabrics. The skin is an important immune organ with non-specific and specific activities. Antimicrobial textiles may interfere with non-specific defence mechanisms like antimicrobial peptides of skin or the resident microflora. The use of antibacterial compounds like silver, copper or triclosan is a matter of debate despite their use for a very long period. Macromolecules with antimicrobial activity like chitosan that can be incorporated into textiles or inert material like carbon fibres or activated charcoal seem to be promising agents. Interaction of textiles with the specific immune system of skin is a rare event but may lead to allergic contact dermatitis. Electronic textiles and other smart textiles offer new areas of usage in health care and risk management but bear their own risks for allergies. PMID:16766877

  14. Reactivity of basic zirconium sulfate during interaction with carbonate, oxalate and phosphate reagents

    International Nuclear Information System (INIS)

    Methods of potentiometry and chemical analysis are used to study basic zirconium sulfate (BZS) interaction with carbonate (Na2CO3, NaHCO3), phosphate (Na3PO4, Na2HPO4, NaH2PO4, H3PO4) and oxalate ((NH4)2C2O4xH2O) reagents. Depending on conditions two different BZS - BZS-1 and BZS-2 are obtained. It is shown that BZS reactivity is defined by the possibility of substitution of oxo- and hydroxoligands and is decreased by increase of its deposition temperature. BZS-1 interaction with carbonate and oxalate reagents takes place at 25 deg C without changing basicity, and with phosphate reagents with basicity decrease up to formation of monophosphate which basicity is about 20%. During BZC-2 interaction oxo- and hydroxo-groups may be completely substituted for acidoligands with formation of nonhydrolysed compounds

  15. Ion exchange reactions in interaction of basic zirconium sulfate with sodium carbonate solution

    International Nuclear Information System (INIS)

    Basic zirconium sulfates, extracted from basic zirconium chloride solution and zirconium disulfate solution, as well as products of their interaction with sodium carbonate solution, which was exposed and not exposed to hydrolysis, were investigated by chemical and NMR spectroscopy methods. It has been established that the process of interaction of the basic zirconium sulfate with sodium carbonate solutions sulfatocarbonatozicrconates and carbonatozirconates of sodium are sequentially formed. In this case carbonate groups, due to different strenght of addition of hydroxogroups in initial basic sulfates, substitute either SOsub(h)sup(2)-)- groups and H2O or SO42--and OH--groups, and sodium ions substitute H3O+-groups. Carbonate groups, if they have substituted sulfato- or hydroxogroup, during hydrolysis of carbonatozirconates are splitted out to a less degree

    The time dependence of the adsorption of myelin basic protein onto dipalmitoyl phosphatidyl glycerol multilayers has been followed directly, using a novel application of a microgravimetric gauge. Our results, supplemented by other data obtained by FTIR, show the ease and versatility of the quartz microbalance for investigating the interaction processes between proteins and phospholipid layers and show that the protein adsorption is accompanied by structural changes in the proteolipid ensemble and adsorbed liquid water; it is furthermore dependent on the mesoscopic defect morphology of the ensemble.

    Full Text Available Recently, the impact of intestinal supersaturation on absorption of poorly water-soluble drugs has raised much interest among researchers. A focus has been mostly to study excipient effects on maintenance of drug supersaturation. The aim of the present study was to better understand the effects of drug-excipient interactions on the level of the anhydrous formulation, upon dispersion in simple buffer media and, in particular, regarding precipitation kinetics. A solid lipid-based formulation comprising PEG-32 stearate and oleic acid (OA (8:2 w/w was developed as a model. Loratadine (pKa = 4.33 and carvedilol (pKa = 8.74 were chosen as basic drugs. UV/FTIR spectroscopy and viscometry were used to characterize drug-OA molecular interactions in solution, while solid formulations were studied using x-ray diffraction, thermal analysis and van’t Hoff solubility-temperature plots. Precipitation kinetics of drug formulations was real-time monitored in phosphate buffer (pH = 6.5 by focused beam reflectance measurements. It was found that the addition of OA in the formulations resulted in substantial drug solubility increase. Although the drug-OA interactions appeared to be partially lost upon formulation dispersion, the extent of precipitation was markedly lowered compared to the formulations without OA. A Precipitation number (Pnc was introduced as a ratio of a relevant residence time of drug in the gastrointestinal tract (GIT to the induction time (the onset time of crystalline precipitation. Without OA, Pnc was already taking critical values (>1, while the anhydrous formulation was still below saturation for both model drugs. Interestingly, the addition of OA resulted in amorphous instead of crystalline precipitates, which is advantageous for drug re-dissolution and absorption. In conclusion, this study provides an improved understanding of OA and basic drug interactions on different levels of in vitro performance for more rational oral formulation

  20. Upper Secondary Students' Understanding of the Basic Physical Interactions in Analogous Atomic and Solar Systems

    2013-08-01

    Comparing the atom to a `tiny solar system' is a common teaching analogy, and the extent to which learners saw the systems as analogous was investigated. English upper secondary students were asked parallel questions about the physical interactions between the components of a simple atomic system and a simple solar system to investigate how they understood the forces acting within the two systems. A sample of just over 100 across the 15-18 age range responded to a pencil-and-paper instrument that asked about four aspects of the two systems. It was found that for both systems, about four fifths of students expected forces to decrease with increasing distance; but that only a little over half expected there to be interactions between the minor constituents (electrons and planets). Most students failed to apply Newton's third law to either system. There was a considerable difference in the extent to which respondents were able to identify the type of force acting in the systems (nearly all for the solar system, but only a small proportion in the case of the atom). The findings are considered in terms of both the limitations of students' understanding of the basic physics and possible implications for the use of the teaching analogy.

    The secondary structure of the naturally occurring isoforms of myelin basic protein (MBP1-8) from human myelin was studied by Fourier transform infrared spectroscopy under a variety of experimental conditions. In aqueous solution each isoform was found to be unstructured. In the presence of negatively charged liquid bilayers MBP1-4 were shown to exhibit an amide I band maximum indicative of the adoption of (alpha) -helical secondary structures. A detailed analysis revealed that significant proportions of (beta) -sheet secondary structure were also present. MBP5 and MBP8, which have significantly less cationic charge than MBP1-4, exhibited an amide I maximum identical to that seen in solution, suggesting that no interaction with the bilayer occurred. Analysis of the lipid CH2 and C equals O stretching vibrations also pointed towards significant interaction of MBP1-4 with the bilayer. The changes in intensity and frequency of these bands which typically accompany the phase transition in the pure bilayer were abolished by addition of the proteins. No such effect was seen for MBP5 and 8, the normal lipid phase transition being apparent. The implications of these results in the aetiology of multiple sclerosis is discussed.

  2. Real-time interactive MR imaging system. Sequence optimization, and basic and clinical evaluations

    International Nuclear Information System (INIS)

    A real-time interactive MR imaging system (real-time MRI) is an MR scanner which has a fast image updating cycle and the ability to freely change slice orientation, just like an ultrasound imaging system. Recently, such a system has been developed and installed on a clinical 1.5-Tesla system. The purpose of this study was to optimize the pulse sequences for clinical use and to evaluate the clinical usefulness and basic functionality of real-time MRI. For T1-weighted imaging, FLASH (fast low angle shot) can be selected, and up to 5 frames per second can be acquired depending on the matrix size. For T2-weighted imaging, true FISP (fast imaging with steady-state precession) can be selected, and up to 4 frames per second can be acquired. Maximum C/N between liver and spleen was obtained at a flip angle of 20 degrees on FLASH. Maximum C/N between cardiac cavity and wall was obtained at a flip angle of 60 degrees on true FISP. Localization of the right and left coronary arteries could be performed within 30 seconds in three volunteers. Although the present real-time MRI system has drawbacks such as low spatial resolution and relatively low contrast resolution, we expect real-time MRI to be one of the most important tools for future clinical MRI.

    The surface forces apparatus and atomic force microscope were used to study the effects of lipid composition and concentrations of myelin basic protein (MBP) on the structure of model lipid bilayers, as well as the interaction forces and adhesion between them. The lipid bilayers had a lipid composition characteristic of the cytoplasmic leaflets of myelin from "normal" (healthy) and "disease-like" [experimental allergic encephalomyelitis (EAE)] animals. They showed significant differences in the adsorption mechanism of MBP. MBP adsorbs on normal bilayers to form a compact film (3-4 nm) with strong intermembrane adhesion (∼0.36 mJ/m(2)), in contrast to its formation of thicker (7-8 nm) swelled films with weaker intermembrane adhesion (∼0.13 mJ/m(2)) on EAE bilayers. MBP preferentially adsorbs to liquid-disordered submicron domains within the lipid membranes, attributed to hydrophobic attractions. These results show a direct connection between the lipid composition of membranes and membrane-protein adsorption mechanisms that affects intermembrane spacing and adhesion and has direct implications for demyelinating diseases.

    Frost, T.P.; Lindsay, J.R.

    1988-01-01

    MAGMIX is a BASIC program designed to predict viscosities at thermal equilibrium of interacting magmas of differing compositions, initial temperatures, crystallinities, crystal sizes, and water content for any mixing proportion between end members. From the viscosities of the end members at thermal equilibrium, it is possible to predict the styles of magma interaction expected for different initial conditions. The program is designed for modeling the type of magma interaction between hypersthenenormative magmas at upper crustal conditions. Utilization of the program to model magma interaction at pressures higher than 200 MPa would require modification of the program to account for the effects of pressure on heat of fusion and magma density. ?? 1988.

  5. DEEBAR - A BASIC interactive computer programme for estimating mean resonance spacings

    International Nuclear Information System (INIS)

    DEEBAR is a BASIC interactive programme, which uses the theories of Dyson and of Dyson and Mehta, to compute estimates of the mean resonance spacings and associated uncertainty statistics from an input file of neutron resonance energies. In applying these theories the broad scale energy dependence of D-bar, as predicted by the ordinary theory of level densities, is taken into account. The mean spacing D-bar ± δD-bar, referred to zero energy of the incident neutrons, is computed from the energies of the first k resonances, for k = 2,3...K in turn and as if no resonances are missing. The user is asked to survey this set of D-bar and δD-bar values and to form a judgement - up to what value of k is the set of resonances complete and what value, in consequence, does the user adopt as the preferred value of D-bar? When the preferred values for k and D-bar have been input, the programme calculates revised values for the level density parameters, consistent with this value for D-bar and with other input information. Two short tables are printed, illustrating the energy variation and spin dependence of D-bar. Dyson's formula based on his Coulomb gas analogy is used for estimating the most likely energies of the topmost bound levels. Finally the quasi-crystalline character of a single level series is exploited by means of a table in which the resonance energies are set alongside an energy ladder whose rungs are regularly spaced with spacing D-bar(E); this comparative table expedites the search for gaps where resonances may have been missed experimentally. Used in conjunction with the program LJPROB, which calculates neutron strengths and compares them against the expected Porter Thomas distribution, estimates of the statistical parameters for use in the unresolved resonance region may be derived.

  6. Four basic levels of the interactions between humanity and the imbalanced Nature

    2013-12-01

    There are the clearly distinguishable four basic levels of interaction the humanity with the imbalanced Nature: 1 Level - Naivety: Self-healing Nature in defiance of the humanity activities. 2 Level - Collaboration: Restoration of Nature in cooperation with humanity. 3 Level - Conflict: The resistance of Nature against the humanity's interference. 4 Level - Disappearance: Nature destroys humanity as the trouble maker. On the first level the people were afraid and respected Nature and are taking from Nature only what Nature gave willingly. Therefore Nature could easy regenerate itself. So it was thousands of years and people become under the false impression that it will be forever. The first signs the end of this period was visible in the era of industrialization. It turned out that resources are not infinite, and the waste of humanity grows much faster than Nature can utilize or dispose it. But in the world still had plenty of the untouched places and industrialization continued to develop rapidly. Thus problems with Nature were dislocated into the colonies rather far off from the prosperous metropolitan countries. The false impression about the man's victory over Nature has increased. Very soon the main untouched place was used, and the global circulations bring the pollutions from colonies to the metropolis. The second level was started as processes to creating the national parks, natural reservations, etc. It was some beginning of the cooperation humanity with Nature. The invasion into the Nature of the colonies was intensified. In addition start increasing the pollution in the metropolis from the waste of resources which have been imported from the colonies. The third level was started and Nature began to resist and revenge to the self-confident man. But man didn't stop and continued create more and more aggressive processes which provoked some avalanches-looks reactions of Nature. Now people can start these avalanches, but cannot stop it. One of these man

  8. Fuel-Coolant Interactions - some Basic Studies at the UKAEA Culham Laboratory

    International Nuclear Information System (INIS)

    In a hypothetical fault sequence important effects of fuel-coolant interactions include voiding and dispersion of core debris as well as the pressure damage usually discussed. The development of the fuel-coolant interaction probably depends on any pre-mixing Weber break-up that may occur, and is therefore a function of the way the fuel and coolant come together. Four contact modes are identified: jetting, shock tube, drops and static, and Culham's experiments have been mainly concerned with simulating the falling drop mode by using molten tin in water. It was observed that the fuel-coolant interaction is a short series of violent coolant oscillations centred at a localized position on the drop, generating a spray of submillimeter sized debris. The interaction started spontaneously at a specific time after the drop first contacted the water. There was a definite limited fuel-coolant interaction zone on a plot of initial coolant temperature versus initial fuel temperature outside which interactions never occurred. The. interaction time was a function of the initial temperatures. Theoretical scaling formulae are given which describe the fuel-coolant interaction zone and dwell time. Bounds of fuel and coolant temperature below which fuel-coolant interactions do not occur are explained by freezing. Upper bounds of fuel and coolant temperatures above which there were no fuel-coolant interactions are interpreted in terms of heat transfer through vapour films of various thicknesses. In conclusion: We have considered the effects of fuel-coolant interactions in a hypothetical fault sequence, emphasising that debris and vapour production as well as the pressure pulse can be important factors. The fuel-coolant interaction has been classified into types, according to possible modes of mixing in the fault sequence. Culham has been studying one type, the self-triggering of falling drops, by simulant experiments. It is found that there is a definite zone of interaction on a plot

    For optical basicity and electronic polarizability, the previous studies basically concentrate on the wavelength range of the visible light region. However, heavy metal oxides glasses have a reputation of being good materials for infrared region. In this study, new data of the average electronic polarizability of the oxide ion α, optical basicity Λ and Yamashita-Kurosawa's interaction parameter A of Bi 2O 3-B 2O 3 glasses have been calculated in a wavelength range from 404.66 to 1083.03 nm. The present investigation suggests that both α and Λ increase gradually with increasing wave number, and A decreases with increasing wave number. Furthermore, close correlations are studied among α, Λ, A and refractive index n in this paper. Particularly, it has been found that a quantitative relationship between electronic polarizability and optical basicity is observed in a wavelength range from 404.66 to 1083.03 nm. Our present study extends over a wide range of α, Λ and A values.

  10. Basics of quantum field theory of electromagnetic interaction processes in single-layer graphene

    Science.gov (United States)

    Hieu Nguyen, Van

    2016-09-01

    The content of this work is the study of electromagnetic interaction in single-layer graphene by means of the perturbation theory. The interaction of electromagnetic field with Dirac fermions in single-layer graphene has a peculiarity: Dirac fermions in graphene interact not only with the electromagnetic wave propagating within the graphene sheet, but also with electromagnetic field propagating from a location outside the graphene sheet and illuminating this sheet. The interaction Hamiltonian of the system comprising electromagnetic field and Dirac fermions fields contains the limits at graphene plane of electromagnetic field vector and scalar potentials which can be shortly called boundary electromagnetic field. The study of S-matrix requires knowing the limits at graphene plane of 2-point Green functions of electromagnetic field which also can be shortly called boundary 2-point Green functions of electromagnetic field. As the first example of the application of perturbation theory, the second order terms in the perturbative expansions of boundary 2-point Green functions of electromagnetic field as well as of 2-point Green functions of Dirac fermion fields are explicitly derived. Further extension of the application of perturbation theory is also discussed.

    Activation of Raf-1 kinase is preceded by a translocation of Raf-1 to the plasma membrane in response to external stimuli. The membrane localization of Raf-1 is facilitated through its interaction with activated Ras and with membrane phospholipids. Previous evidence suggests that the interaction of Raf-1 with Ras is mediated by two distinct domains within the N-terminal region of Raf-1 comprising amino acid residues 51-131 and residues 139-184, the latter of which codes for a zinc containing cysteine-rich domain. The cysteine-rich domain of Raf-1 is also reported to associate with other proteins, such as 14-3-3, and for selectively binding acidic phospholipids, particularly phosphatidylserine (PS). In the present study, we have investigated the consequences of progressive deletions and point mutations within the cysteine-rich domain of Raf-1 on its ability to bind PS. A reduced interaction with PS was observed in vitro for all deletion mutants of Raf-1 expressed either as full-length proteins or as fragments containing the isolated cysteine-rich domain. In particular, the cluster of basic amino acids R143, K144, and K148 appeared to be critical for interaction with PS, since substitution of all three residues to alanine resulted in a protein that failed to interact with liposomes enriched for PS. Expression of Raf-1 in vivo, containing point mutations in the cysteine-rich domain resulted in a truncated polypeptide that lacked both the Ras and PS binding sites and could no longer translocate to the plasma membrane upon serum stimulation. These results indicate that the basic residues 143, 144 and 148 in the anterior half of Raf-1 cysteine-rich domain play a role in the association with the lipid bilayer and possibly in protein stability, therefore they might contribute to Raf-1 localization and subsequent activation.

    We have studied the effect of physiological amounts of myelin basic protein (MBP) on pure dimyristoyl L-{alpha}-phosphatidic acid (DMPA) oriented membranes. The investigation has been carried out using several complementary experimental methods to provide a detailed characterization of the proteo-lipid complexes. In particular, taking advantage of the power of the quasi-elastic neutron scattering (QENS) technique as optimal probe in biology, a significant effect is suggested to be induced by MBP on the anisotropy of lipid dynamics across the liquid-gel phase transition. Thus, the enhancement of the spatially restricted, vertical translation motion of DMPA is suggested to be the main responsible for the increased contribution of the out of plane lipid dynamics observed at 340 K.

    In1879 George Howard Darwin theoretically analyzed the outward spiraling orbit of Moon and the subsequent lengthening of the Mean Solar Day. The author redid the same analysis based on the fact that Moon was receding at the rate of 3.8 cm per annum. Basic Mechanics of Earth-Moon is worked out and various system parameters are optimized to fit the given boundary condition obtained by Apollo Mission and other modern means of observations. Based on this theoretical formulation the theoretical graph of the lengthening of the Mean Solar Day with respect to time is drawn and is compared with the observational graph of the same based on pale ontological data, paleo tidal data and iron-banded formation. The observational data on Mean Solar Day is found to follow the theoretical smooth curve in post-Cambrian Era but is found to deviate in the remote past. This deviation is corrected by taking the evolving form of Moment of Inertia of Earth. The deviation of the observed data prompts the Author to suggest that the leng...

    The transcription factor CCAAT/enhancer-binding protein α (C/EBPα) regulates cell cycle arrest and terminal differentiation of neutrophils and adipocytes. Mutations in the basic leucine zipper domain (bZip) of C/EBPα are associated with acute myeloid leukemia. A widely used murine transforming C/EBPα basic region mutant (BRM2) entails two bZip point mutations (I294A/R297A). BRM2 has been discordantly described as defective for DNA binding or defective for interaction with E2F. We have separated the two BRM2 mutations to shed light on the intertwined reciprocity between C/EBPα-E2F-DNA interactions. Both, C/EBPα I294A and R297A retain transactivation capacity and interaction with E2F-DP. The C/EBPα R297A mutation destabilized DNA binding, whereas the C/EBPα I294A mutation enhanced binding to DNA. The C/EBPα R297A mutant, like BRM2, displayed enhanced interaction with E2F-DP but failed to repress E2F-dependent transactivation although both mutants were readily suppressed by E2F1 for transcription through C/EBP cis-regulatory sites. In contrast, the DNA binding enhanced C/EBPα I294A mutant displayed increased repression of E2F-DP mediated transactivation and resisted E2F-DP mediated repression. Thus, the efficient repression of E2F dependent S-phase genes and the activation of differentiation genes reside in the balanced DNA binding capacity of C/EBPα.

    Full Text Available The previous survey identified 70 basic helix-loop-helix (bHLH proteins, but it was proved to be incomplete, and the functional information and regulatory networks of frog bHLH transcription factors were not fully known. Therefore, we conducted an updated genome-wide survey in the Xenopus tropicalis genome project databases and identified 105 bHLH sequences. Among the retrieved 105 sequences, phylogenetic analyses revealed that 103 bHLH proteins belonged to 43 families or subfamilies with 46, 26, 11, 3, 15, and 4 members in the corresponding supergroups. Next, gene ontology (GO enrichment analyses showed 65 significant GO annotations of biological processes and molecular functions and KEGG pathways counted in frequency. To explore the functional pathways, regulatory gene networks, and/or related gene groups coding for Xenopus tropicalis bHLH proteins, the identified bHLH genes were put into the databases KOBAS and STRING to get the signaling information of pathways and protein interaction networks according to available public databases and known protein interactions. From the genome annotation and pathway analysis using KOBAS, we identified 16 pathways in the Xenopus tropicalis genome. From the STRING interaction analysis, 68 hub proteins were identified, and many hub proteins created a tight network or a functional module within the protein families.

    The connection between fundamental interactions acting in molecules in a fluid and macroscopically measured properties, such as the viscosity between colloidal particles coated with polymers, is studied here. The role that hydrodynamic and Brownian forces play in colloidal dispersions is also discussed. It is argued that many-body systems in which all these interactions take place can be accurately solved using computational simulation tools. One of those modern tools is the technique known as dissipative particle dynamics, which incorporates Brownian and hydrodynamic forces, as well as basic conservative interactions. A case study is reported, as an example of the applications of this technique, which consists of the prediction of the viscosity and friction between two opposing parallel surfaces covered with polymer chains, under the influence of a steady flow. This work is intended to serve as an introduction to the subject of colloidal dispersions and computer simulations, for final-year undergraduate students and beginning graduate students who are interested in beginning research in soft matter systems. To that end, a computational code is included that students can use right away to study complex fluids in equilibrium.

  20. Geographic-didactical games as interactive tools to test and improve student's basic knowledge in Physical Geography

    Winkler, S.; Tintrup Gen. Suntrup, A.

    2009-04-01

    Due to an increasing disproportion between experienced teaching staff and student numbers at German universities, the time available for teaching the fundamental basic knowledge in Physical Geography was condensed during the past decade. Unfortunately, this mainly has been achieved at the expense of practical lessons of testing student's knowledge. The recent introduction of the Bachelor/Master degree has not solved this problem, but rather accelerated that tend. The "losers" of this tendency are those students enrolled in trainee teacher studies in Geography. In conjunction with the recent modifications of the study programs putting more focus on applied or specialized fields of Geography and its methodology, the trainee teacher students often express their critics and urgently demand opportunities to improve and test their basic knowledge (because it is especially that knowledge, they need at school and for their traditional examination). As the study program is quite dense, there is no room for special courses or seminars. By contrast, one has to use some free time slots available e.g. in the evenings of the usually quite long German excursions or of weekend seminars. However, after a day in the field or in the classroom, the teacher has to find a method owing enough excitement and clearly visible benefit for the students to achieve sufficient motivation. Interactive geographic-didactical games have been developed exclusively for this purpose and applied at different occasions. Those games had the goal of testing student's basic knowledge in a rather unconventional and "casual" style in order to motivate active participation. Most of the games could be played in small groups of students with the teacher only occasionally being involved as referee. Of course, the games had the general aim of improving the basic knowledge - or at least give the students the possibility to discover their own strength (or weakness) just before it is too late (as it e.g. would be

    The present study compares the highly interactive cloud-classroom (HIC) system with traditional methods of teaching materials science that utilize crystal structure picture or real crystal structure model, in order to examine its learning effectiveness across three dimensions: knowledge, comprehension and application. The aim of this study was to evaluate the (HIC) system, which incorporates augmented reality, virtual reality and cloud-classroom to teach basic materials science courses. The study followed a pretest-posttest quasi-experimental research design. A total of 92 students (aged 19-20 years), in a second-year undergraduate program, participated in this 18-week-long experiment. The students were divided into an experimental group and a control group. The experimental group (36 males and 10 females) was instructed utilizing the HIC system, while the control group (34 males and 12 females) was led through traditional teaching methods. Pretest, posttest, and delayed posttest scores were evaluated by multivariate analysis of covariance. The results indicated that participants in the experimental group who used the HIC system outperformed the control group, in the both posttest and delayed posttest, across three learning dimensions. Based on these results, the HIC system is recommended to be incorporated in formal materials science learning settings.

    Full Text Available Abstract Background The myelin sheath is a multilamellar membrane structure wrapped around the axon, enabling the saltatory conduction of nerve impulses in vertebrates. Myelin basic protein, one of the most abundant myelin-specific proteins, is an intrinsically disordered protein that has been shown to bind calmodulin. In this study, we focus on a 19-mer synthetic peptide from the predicted calmodulin-binding segment near the C-terminus of human myelin basic protein. Results The interaction of native human myelin basic protein with calmodulin was confirmed by affinity chromatography. The binding of the myelin basic protein peptide to calmodulin was tested with isothermal titration calorimetry (ITC in different temperatures, and Kd was observed to be in the low μM range, as previously observed for full-length myelin basic protein. Surface plasmon resonance showed that the peptide bound to calmodulin, and binding was accompanied by a conformational change; furthermore, gel filtration chromatography indicated a decrease in the hydrodynamic radius of calmodulin in the presence of the peptide. NMR spectroscopy was used to map the binding area to reside mainly within the hydrophobic pocket of the C-terminal lobe of calmodulin. The solution structure obtained by small-angle X-ray scattering indicates binding of the myelin basic protein peptide into the interlobal groove of calmodulin, while calmodulin remains in an extended conformation. Conclusion Taken together, our results give a detailed structural insight into the interaction of calmodulin with a C-terminal segment of a major myelin protein, the myelin basic protein. The used 19-mer peptide interacts mainly with the C-terminal lobe of calmodulin, and a conformational change accompanies binding, suggesting a novel mode of calmodulin-target protein interaction. Calmodulin does not collapse and wrap around the peptide tightly; instead, it remains in an extended conformation in the solution structure

    The basic characteristics of the sensation of linear horizontal motion have been studied. Objective linear motion was induced by means of a moving cart. Visually induced linear motion perception (linearvection) was obtained by projection of moving images at the periphery of the visual field. Image velocity and luminance thresholds for the appearance of linearvection have been measured and are in the range of those for image motion detection (without sensation of self motion) by the visual system. Latencies of onset are around 1 sec and short term adaptation has been shown. The dynamic range of the visual analyzer as judged by frequency analysis is lower than the vestibular analyzer. Conflicting situations in which visual cues contradict vestibular and other proprioceptive cues show, in the case of linearvection a dominance of vision which supports the idea of an essential although not independent role of vision in self motion perception.

    Human embryonic stem (ES) cells can be maintained in an undifferentiated state if the culture medium is first conditioned on a layer of mouse embryonic fibroblast (MEF) feeder cells. Here we show that human ES cell proliferation is coordinated by MEF-secreted heparan sulfate proteoglycans (HSPG) in conditioned medium (CM). These HSPG and other heparinoids can stabilize basic fibroblast growth factor (FGF2) in unconditioned medium at levels comparable to those observed in CM. They also directly mediate binding of FGF2 to the human ES cell surface, and their removal from CM impairs proliferation. Finally, we have developed a purification scheme for MEF-secreted HSPG in CM. Using column chromatography, immunoblotting, and mass spectrometry-based proteomic analysis, we have identified multiple HSPG species in CM. The results demonstrate that HSPG are key signaling cofactors in CM-based human ES cell culture.

    There are two types of lenses are used, namely a convex lens and a concave lens. Microscope is a tool that uses two convex lenses as the eyepiece and objective lens because it can form a magnified image. Instead concave lens is usually used as a spectacle lens for nearsightedness patients because the distance of image formed is closer than the distance of the object. Just like a mirror, the image formation by lenses also can be conveniently determined with ray diagrams. Therefore, this research aims to create a simulation of ray diagrams in the process of image formation by lenses and their applications using Macro Visual Basic in Microsoft PowerPoint. Lenses applications made are the microscope simulation and the combined lenses which consist of a concave-convex lens combined and a convex-concave lens combined. This research begins with the preparation of material on the image formation by lenses and their application. Second, made an appearance on the program which consists of a PowerPoint slide, CommandButton, Textbox, OptionButton, Shape and others then wrote programs in Macro Visual Basic procedure to active the command to do. Input of this simulation can be given in the form of object distance, focal point distance of lens and height of objects. The data will be processed according to commands contained in macros procedure to result image distance, image height, image magnification and the properties of image. In addition to result the data, media can also provide output in the form of ray diagrams simulation on the image formation that can be used to assist students understanding the image formation by lenses.

    Full Text Available Background: There are models of the development of personality disorders which include individual differences in attachment relationships as causal factors contributed in explanation of these phenomena. The dimensional view of personality disorders represents these conditions as extreme variants of normal personality continua. This study investigated main and interactional effects of attachment styles and personality traits in relation to borderline characteristics. Materials and Methods: The current study was conducted in expo fact context. Randomly selected 603 participants (134 male  469 female from Tabriz Payam-e-Noor, Tarbait Moallem of Azarbaijan and Sarab Payam-e-Noor university students took part in this research. Participants answered to Borderline Personality Inventory (BPI, Eysenck Personality Questionnaire Revised, Short form (EPQ-RS and Adult Attachment Inventory (AAI. Data were analyzed using two way analysis of variance method.Results: Results indicate main effects of attachment styles and personality traits, so, individual with ambivalent insecure attachment experience more intensity of borderline traits than individual with avoidant insecure and secure attachments. Individual with high psychoticim and neuroticism traits experience more intensity of borderline characteristics than individual with extraversion personality traits. Also, there are no interactional effects of attachment styles and personality traits in relation to borderline characteristics. Conclusion: These findings reiterate contribution of childhood risk factors in developing borderline personality disorder, especially in children with emotionally vulnerability.

  18. Altered transfer of momentary mental states (ATOMS as the basic unit of psychosis liability in interaction with environment and emotions.

    Directory of Open Access Journals (Sweden)

    Johanna T W Wigman

    Full Text Available Psychotic disorders are thought to represent altered neural function. However, research has failed to map diagnostic categories to alterations in neural networks. It is proposed that the basic unit of psychotic psychopathology is the moment-to-moment expression of subtle anomalous experiences of subclinical psychosis, and particularly its tendency to persist from moment-to-moment in daily life, under the influence of familial, environmental, emotional and cognitive factors.In a general population twin sample (n = 579 and in a study of patients with psychotic disorder (n = 57, their non-psychotic siblings (n = 59 and unrelated controls (n = 75, the experience sampling paradigm (ESM; repetitive, random sampling of momentary mental states and context was applied. We analysed, in a within-person prospective design, (i transfer of momentary anomalous experience at time point (t-1 to time point (t in daily life, and (ii moderating effects of negative affect, positive affect, daily stressors, IQ and childhood trauma. Additionally, (iii familial associations between persistence of momentary anomalous experience and psychotic symptomatology were investigated. Higher level of schizotypy in the twins (but not higher level of psychotic symptoms in patients predicted more persistence of momentary anomalous experience in daily life, both within subjects and across relatives. Persistence of momentary anomalous experience was highest in patients, intermediate in their siblings and lowest in controls. In both studies, persistence of momentary anomalous experience was moderated by higher levels of negative affect, daily stressors and childhood trauma (only in twins, and by lower levels of positive affect. The study of alterations in the moment-to-moment transfer of subtle anomalous experience of psychosis, resulting in their persistence, helps to explain why psychotic and emotional dysregulation tend to cluster in a single phenotype such as

    Classroom interaction is the most essential way in cultivating students ' creativity. One academic year' s observation of the basic course classroom interaction in military transportation academy and a survey conducted among both the students and the teachers reveal that despite the teachers' efforts, the overall result of the classroom interaction is far from satisfactory. The main reasons are : teachers do not do enough studies on interaction teaching; the big number of students in a class hinders the effective classroom interaction;the evaluation criteria are not specific enough to guide the interaction teaching. Therefore, to really"activate"the classroom, first, teachers should do more studies on interaction teaching. Second, the number of students in a class should be reduced so as to ensure an interaction - friendly environment. Finally, more specific teaching evaluation criteria should be made to motivate classroom interaction.%课堂互动教学是创新能力培养的重要途径。通过对某高校基础课课堂互动教学一学年的观察和对教员及学员的问卷调查,发现大部分课堂都在积极尝试互动教学,但是总体来讲效果不尽人意。主要原因是教员对互动教学研究不够、大班授课、教学评价标准不具体。为了切实让课堂"动"起来,首先,教员要深入开展互动教学研究;其次,要尽可能地安排小班授课,为互动教学创造条件;最后,教学评价标准中对互动效果的评价标准要更具体、更具操作性。

  4. Potential sodium–CO2 interaction of a supercritical CO2 power conversion option coupled with an SFR: Basic nature and design issues

    International Nuclear Information System (INIS)

    Highlights: ► For the supercritical CO2 Brayton cycle option for SFR power conversion. ► A boundary failure and consequent sodium–CO2 interaction was studied. ► The kinetics depends heavily on temperatures, but is not sensitive to gas velocities. ► Two-zone reaction model was proposed with a threshold temperature of 460 °C. ► Practical design and safety issues relevant to plant safety were discussed as well. -- Abstract: The supercritical CO2 Brayton cycle option for energy conversion in a sodium-cooled fast reactor (SFR) has recently received a great deal of attention due to highly reliable system design features that make it essentially free from risk of a sodium–water reaction in a traditional Rankine cycle power conversion. Although this novel approach will yield significant improvements in overall plant safety and energy utilization, it raises the risk of pressure boundary failure and consequent sodium–CO2 interaction. Since an understanding of the interaction mechanism is directly relevant to safety issues for the advanced SFR design, the kinetic behavior of sodium–CO2 interaction and its basic nature were investigated in this study. Experiments were performed for sodium temperatures ranging from 200 to 600 °C. The results indicated that the reaction kinetics over the sodium temperature range of 300–550 °C depends heavily on the temperature but is not sensitive to the velocity of CO2 flowing over the gas–liquid reacting interface explored in this study. The rate of the chemical reaction was determined by measuring the gas concentration of the CO/CO2 mixture, and a two-zone reaction model was proposed with a threshold temperature of 460 °C. The kinetic parameters, i.e., the activation energies according to reaction zones, were obtained experimentally and the corresponding model parameters were identified. Finally, practical design and safety issues regarding a wastage scenario and the potential plugging of faulty heat exchanger

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames. Chapter 2 introduces the wavelet transform, contrasts it with the short-time Fourier transform and clarifies the names of the different types of wavelet transforms. Chapter 3 links multiresolution analysis, orthonormal wavelets and the design of digital filters. Chapter 4 gives a tour d'horizon of topics of current interest: wave...

  12. OsbHLH148, a basic helix-loop-helix protein, interacts with OsJAZ proteins in a jasmonate signaling pathway leading to drought tolerance in rice.

    Jasmonates play important roles in development, stress responses and defense in plants. Here, we report the results of a study using a functional genomics approach that identified a rice basic helix-loop-helix domain gene, OsbHLH148, that conferred drought tolerance as a component of the jasmonate signaling module in rice. OsbHLH148 transcript levels were rapidly increased by treatment with methyl jasmonate (MeJA) or abscisic acid, and abiotic stresses including dehydration, high salinity, low temperature and wounding. Transgenic over-expression of OsbHLH148 in rice confers plant tolerance to drought stress. Expression profiling followed by DNA microarray and RNA gel-blot analyses of transgenic versus wild-type rice identified genes that are up-regulated by OsbHLH148 over-expression. These include OsDREB and OsJAZ genes that are involved in stress responses and the jasmonate signaling pathway, respectively. OsJAZ1, a rice ZIM domain protein, interacted with OsbHLH148 in yeast two-hybrid and pull-down assays, but it interacted with the putative OsCOI1 only in the presence of coronatine. Furthermore, the OsJAZ1 protein was degraded by rice and Arabidopsis extracts in the presence of coronatine, and its degradation was inhibited by MG132, a 26S proteasome inhibitor, suggesting 26S proteasome-mediated degradation of OsJAZ1 via the SCF(OsCOI1) complex. The transcription level of OsJAZ1 increased upon exposure of rice to MeJA. These results show that OsJAZ1 could act as a transcriptional regulator of the OsbHLH148-related jasmonate signaling pathway leading to drought tolerance. Thus, our study suggests that OsbHLH148 acts on an initial response of jasmonate-regulated gene expression toward drought tolerance, constituting the OsbHLH148-OsJAZ-OsCOI1 signaling module in rice.

Este trabalho teve como objetivo estudar a interação entre atributos atrativos e obrigatórios. Para tanto, utilizou-se um delineamento experimental do tipo fatorial completo com quatro atributos de video-locadoras (dois obrigatórios e dois atrativos, cada um a dois níveis, entrevistando-se 152 clientes. Verificou-se que os atributos atrativos apresentaram um maior impacto na satisfação dos clientes se os atributos obrigatórios estiverem presentes. A implicação gerencial desse resultado é que os atributos obrigatórios devem ser identificados e mantidos em um nível adequado, pois somente assim os atributos atrativos terão pleno efeito no aumento da satisfação dos clientes.Kano Model distinguishes service attributes in three types: basic, excitement and performance attributes. This work has as objective to verify how these attributes interact to proportionate satisfaction to customers. A full factorial experiment, using a sample of 152 customers of video rental stores, was used to study the interaction among four attributes (two basic and two excitements. The results show that the excitement attributes had less impact on customer satisfaction if the basic attributes were not fulfilled. The managerial implication of these results is that service companies should identify and fulfill the basic attributes in order to the excitement attributes having full impact on customer satisfaction.

    A novel NbO-type MOF is reported based on a palladated organic linker, showing a remarkable gravimetric and volumetric CO2 uptake, reaching 201.8 cm(3) g(-1) (9.0 mmol g(-1), 39.7 wt%) and 187.8 cm(3) cm(-3) at 273 K and 1 bar, respectively. Accurate theoretical calculations revealed that the exceptional CO2 uptake is due to the combination of Lewis base Pd(ii)-CO2 (24.3 kJ mol(-1)) and Lewis acid Cu(ii)-CO2 (30.3 kJ mol(-1)) interactions, as well as synergistic pore size effects.

    Progress in immunology continues to grow exponentially every year. New applications of this knowledge are being developed for a broad range of clinical conditions. Conversely, the study of primary and secondary immunodeficiencies is helping to elucidate the intricate mechanisms of the immune system. We have selected a few of the most significant contributions to the fields of basic and clinical immunology published between October 2001 and October 2002. Our choice of topics in basic immunology included the description of T-bet as a determinant factor for T(H)1 differentiation, the role of the activation-induced cytosine deaminase gene in B-cell development, the characterization of CD4(+)CD25(+) regulatory T cells, and the use of dynamic imaging to study MHC class II transport and T-cell and dendritic cell membrane interactions. Articles related to clinical immunology that were selected for review include the description of immunodeficiency caused by caspase 8 deficiency; a case series report on X-linked agammaglobulinemia; the mechanism of action, efficacy, and complications of intravenous immunoglobulin; mechanisms of autoimmunity diseases; and advances in HIV pathogenesis and vaccine development. We also reviewed two articles that explore the possible alterations of the immune system caused by spaceflights, a new field with increasing importance as human space expeditions become a reality in the 21st century.

  13. Phactr3/scapinin, a member of protein phosphatase 1 and actin regulator (phactr family, interacts with the plasma membrane via basic and hydrophobic residues in the N-terminus.

    Directory of Open Access Journals (Sweden)

    Akihiro Itoh

    Full Text Available Proteins that belong to the protein phosphatase 1 and actin regulator (phactr family are involved in cell motility and morphogenesis. However, the mechanisms that regulate the actin cytoskeleton are poorly understood. We have previously shown that phactr3, also known as scapinin, localizes to the plasma membrane, including lamellipodia and membrane ruffles. In the present study, experiments using deletion and point mutants showed that the basic and hydrophobic residues in the N-terminus play crucial roles in the localization to the plasma membrane. A BH analysis (http://helixweb.nih.gov/bhsearch is a program developed to identify membrane-binding domains that comprise basic and hydrophobic residues in membrane proteins. We applied this program to phactr3. The results of the BH plot analysis agreed with the experimentally determined region that is responsible for the localization of phactr3 to the plasma membrane. In vitro experiments showed that the N-terminal itself binds to liposomes and acidic phospholipids. In addition, we showed that the interaction with the plasma membrane via the N-terminal membrane-binding sequence is required for phactr3-induced morphological changes in Cos7 cells. The membrane-binding sequence in the N-terminus is highly conserved in all members of the phactr family. Our findings may provide a molecular basis for understanding the mechanisms that allow phactr proteins to regulate cell morphogenesis.

    Plant trichomes and root hairs are powerful models for the study of cell fate determination. In Arabidopsis thaliana, trichome and root hair initiation requires a combination of three groups of proteins, including the WD40 repeat protein transparent TESTA GLABRA1 (TTG1), R2R3 repeat MYB protein GLABRA1 (GL1), or werewolf (WER) and the IIIf subfamily of basic helix-loop-helix (bHLH) protein GLABRA3 (GL3) or enhancer of GLABRA3 (EGL3). The bHLH component acts as a docking site for TTG1 and MYB proteins. Here, we isolated a mutant showing defects in trichome and root hair patterning that carried a point mutation (R173H) in AtMYC1 that encodes the fourth member of IIIf bHLH family protein. Genetic analysis revealed partial redundant yet distinct function between AtMYC1 and GL3/EGL3. GLABRA2 (GL2), an important transcription factor involved in trichome and root hair control, was down-regulated in Atmyc1 plants, suggesting the requirement of AtMYC1 for appropriate GL2 transcription. Like its homologs, AtMYC1 formed a complex with TTG1 and MYB proteins but did not dimerized. In addition, the interaction of AtMYC1 with MYB proteins and TTG1 was abrogated by the R173H substitution in Atmyc1-1. We found that this amino acid (Arg) is conserved in the AtMYC1 homologs GL3/EGL3 and that it is essential for their interaction with MYB proteins and for their proper functions. Our findings indicate that AtMYC1 is an important regulator of trichome and root hair initiation, and they reveal a novel amino acid necessary for protein-protein interactions and gene function in IIIf subfamily bHLH transcription factors.

  8. Directed basic research

    International Nuclear Information System (INIS)

    In its execution, and in the requirement of no other deliverables than knowledge generation, directed basic research is no different from conventional (self-directed) basic research. The selected areas are determined in a national perspective. Directed Basic Research may be in an area where the knowledge generation would benefit Indian Society in the long term, or it may be in an area where the results of the research would benefit Indian Industry or our strategic interests in the long term. India can become a global innovation leader provided we have technology foresight to make the right technology choices, provided we introduce coherent synergy (a phrase I coined a few years back in this context) in our science and technology related activities and provided we establish an effective innovation ecosystem. We must also selectively promote some technology areas through directed basic research. Sustainable economic development in the future requires strong and increased funding of basic research. While directed basic research should be encouraged, self-directed basic research should also receive substantially increased support. (author)

    1982-01-01

    BASIC Stress Analysis aims to help students to become proficient at BASIC programming by actually using it in an important engineering subject. It also enables the student to use computing as a means of learning stress analysis because writing a program is analogous to teaching-it is necessary to understand the subject matter. The book begins by introducing the BASIC approach and the concept of stress analysis at first- and second-year undergraduate level. Subsequent chapters contain a summary of relevant theory, worked examples containing computer programs, and a set of problems. Topics c

  10. The Second Extracellular Loop of Pore-Forming Subunits of ATP-Binding Cassette Transporters for Basic Amino Acids Plays a Crucial Role in Interaction with the Cognate Solute Binding Protein(s)▿

    Science.gov (United States)

    Eckey, Viola; Weidlich, Daniela; Landmesser, Heidi; Bergmann, Ulf; Schneider, Erwin

    2010-01-01

    In the thermophile Geobacillus stearothermophilus, the uptake of basic amino acids is mediated by an ABC transporter composed of the substrate binding protein (receptor) ArtJ and a homodimer each of the pore-forming subunit, ArtM, and the nucleotide-binding subunit, ArtP. We recently identified two putative binding sites in ArtJ that might interact with the Art(MP)2 complex, thereby initiating the transport cycle (A. Vahedi-Faridi et al., J. Mol. Biol. 375:448-459, 2008). Here we investigated the contribution of charged amino acid residues in the second extracellular loop of ArtM to contact with ArtJ. Our results demonstrate a crucial role for residues K177, R185, and E188, since mutations to oppositely charged amino acids or glutamine led to a complete loss of ArtJ-stimulated ATPase activity of the complex variants in proteoliposomes. The defects could not be suppressed by ArtJ variants carrying mutations in site I (K39E and K152E) or II (E163K and D170K), suggesting a more complex interplay than that by a single salt bridge. These findings were supported by cross-linking assays demonstrating physical proximity between ArtJ(N166C) and ArtM(E182C). The importance of positively charged residues for receptor-transporter interaction was underscored by mutational analysis of the closely related transporter HisJ/LAO-HisQMP2 of Salmonella enterica serovar Typhimurium. While transporter variants with mutated positively charged residues in HisQ displayed residual ATPase activities, corresponding mutants of HisM could no longer be stimulated by HisJ/LAO. Interestingly, the ATPase activity of the HisQM(K187E)P2 variant was inhibited by l- and d-histidine in detergent, suggesting a role of the residue in preventing free histidine from gaining access to the substrate binding site within HisQM.

    CERN Document Server

    Moliton, André

    2007-01-01

    Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is uniquely suited to students of materials science. Many competing texts focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves. Professor André Moliton is Director of the Unité de Microélectronique, Optoélectronique et Polymères (Université de Limoges, France), which brings together three groups studying the optoelectronics of molecular and polymer layers, micro-optoelectronic systems for teleco...

    My invitation from this Journal's Editor, Felicia Cox, to provide a paper for this themed issue, included the sentence 'I was wondering if you or a colleague would like to contribute a back to basics article on the relevant standards and guidelines for decontamination, including what is compliance?'. The reason it is so interesting to me is that the term 'back to basics' implies reverting to a simpler time in life - when by just sticking to the rules, life became easier. However, with decontamination this is not actually true.

  2. Basics of quantum plasmonics

    Science.gov (United States)

    Hieu Nguyen, Van; Nguyen, Bich Ha

    2015-01-01

    The present work is a topical review of the theoretical research on the quantum theory of plasmons and plasmon-photon interaction. The plasmons are defined as the quanta of the quantized plasmonic field. The corresponding classical plasmonic field was constructed on the basis of the study of collective oscillations of the electron gas in the solid. The electron-electron Coulomb interaction is taken into account. The explicit forms of the plasmon-photon interaction Lagrangian in canonical quantum mechanics and the plasmon-photon interaction action functional in the functional integral approach are derived. They all show that the interaction processes are nonlocal ones. The physical origin of the nonlocality is the complex structure of plasmons as composite quasiparticles: they cannot be considered as point particles, as was assumed in all phenomenological theories.

  3. Basics of RF electronics

    CERN Document Server

    Gallo, A

    2011-01-01

    RF electronics deals with the generation, acquisition and manipulation of high-frequency signals. In particle accelerators signals of this kind are abundant, especially in the RF and beam diagnostics systems. In modern machines the complexity of the electronics assemblies dedicated to RF manipulation, beam diagnostics, and feedbacks is continuously increasing, following the demands for improvement of accelerator performance. However, these systems, and in particular their front-ends and back-ends, still rely on well-established basic hardware components and techniques, while down-converted and acquired signals are digitally processed exploiting the rapidly growing computational capability offered by the available technology. This lecture reviews the operational principles of the basic building blocks used for the treatment of high-frequency signals. Devices such as mixers, phase and amplitude detectors, modulators, filters, switches, directional couplers, oscillators, amplifiers, attenuators, and others are d...

    Basic Plasma Physics is designed to serve as an introductory compact textbook for advanced undergraduate, postgraduate and research students taking plasma physics as one of their subject of study for the first time. It covers the current syllabus of plasma physics offered by the most universities and technical institutions. The book requires no background in plasma physics but only elementary knowledge of basic physics and mathematics. Emphasis has been given on the analytical approach. Topics are developed from first principle so that the students can learn through self-study. One chapter has been devoted to describe some practical aspects of plasma physics. Each chapter contains a good number of solved and unsolved problems and a variety of review questions, mostly taken from recent examination papers. Some classroom experiments described in the book will surely help students as well as instructors.

    CERN Document Server

    Blyth, T S

    2002-01-01

    Basic Linear Algebra is a text for first year students leading from concrete examples to abstract theorems, via tutorial-type exercises. More exercises (of the kind a student may expect in examination papers) are grouped at the end of each section. The book covers the most important basics of any first course on linear algebra, explaining the algebra of matrices with applications to analytic geometry, systems of linear equations, difference equations and complex numbers. Linear equations are treated via Hermite normal forms which provides a successful and concrete explanation of the notion of linear independence. Another important highlight is the connection between linear mappings and matrices leading to the change of basis theorem which opens the door to the notion of similarity. This new and revised edition features additional exercises and coverage of Cramer's rule (omitted from the first edition). However, it is the new, extra chapter on computer assistance that will be of particular interest to readers:...

  6. Basic electronic circuits

    CERN Document Server

    Buckley, P M

    1980-01-01

    In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli­ cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encounte...

  7. Basics of statistical physics

    CERN Document Server

    Müller-Kirsten, Harald J W

    2013-01-01

    Statistics links microscopic and macroscopic phenomena, and requires for this reason a large number of microscopic elements like atoms. The results are values of maximum probability or of averaging. This introduction to statistical physics concentrates on the basic principles, and attempts to explain these in simple terms supplemented by numerous examples. These basic principles include the difference between classical and quantum statistics, a priori probabilities as related to degeneracies, the vital aspect of indistinguishability as compared with distinguishability in classical physics, the differences between conserved and non-conserved elements, the different ways of counting arrangements in the three statistics (Maxwell-Boltzmann, Fermi-Dirac, Bose-Einstein), the difference between maximization of the number of arrangements of elements, and averaging in the Darwin-Fowler method. Significant applications to solids, radiation and electrons in metals are treated in separate chapters, as well as Bose-Eins...

    Leal-Calderon, Fernando; Schmitt, Véronique

    2007-01-01

    Emulsions are generally made out of two immiscible fluids like oil and water, one being dispersed in the second in the presence of surface-active compounds.They are used as intermediate or end products in a huge range of areas including the food, chemical, cosmetic, pharmaceutical, paint, and coating industries. Besides the broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physics and chemistry. This book aims to give an overview of the most recent advances in emulsion science. The basic principles, covering aspects of emulsions from their preparation to their destruction, are presented in close relation to both the fundamental physics and the applications of these materials.

    2012-01-01

    Spatial interaction between tourist origin and destination is a key factor affecting tourist behavior and tourism industry. Usually, such a spatial interaction was described by gravity models. However, tourism gravity models used to adopt power deterrence function to describe the spatial friction effect, which is an analogy with Newton's gravity model, are hard to overcome some inherent defects. Therefore, Wilson's model with exponential deterrence function becomes a possible alternative. Based on Wilson's model, a basic form of tourism gravity model is presented with three main explanatory variables: attractiveness of tourist destination, emissiveness of tourist origin, and spatial damping between the destination and origin. Two coefficients, a (income elasticity) and β (spatial damping) in this model are also need to be evaluated. We used the traditional regression method to estimate the value of a. As to p, two new methods, "population particle pattern method" and "integral method on tourist amount" are used to estimate it. The results show that: 1) α = 0.64 and β = 0.00322 are at the national average level in the 2000s; 2) a becomes larger as the field-pixel becomes smaller. For provincial, municipal, county, and township levels, the values of β are 0.00044, 0.0014, 0.0044 and 0.014, respectively; 3) affected by spatial damping, the average travel radius of domestic residents is about 300 km. By the application of this model, attractiveness of each province of China and provincial tourist market shares of Chengdu city are calculated. The results show that: 1) from 2004 to 2008, the average tourism attraction of Sichuan, Liaoning and Yunnan rank the top three, while Ningxia, Qinghai and Inner Mongolia rank the bottom three; 2) from 1999 to 2008, in terms of tourism attraction at provincial level, Xizang has the biggest increase in the ranking, while Shanghai has the greatest decline in the ranking. 3) The results of theoretical calculation on Chengdu city

    Full Text Available Currently Indonesia is the world largest palm oil producer with production volume reaching 16 million tones per annum. The high crude oil and ethylene prices in the last 3 – 4 years contribute to the healthy demand growth for basic oleochemicals: fatty acids and fatty alcohols. Oleochemicals are starting to replace crude oil derived products in various applications. As widely practiced in petrochemical industry, catalyst plays a very important role in the production of basic oleochemicals. Catalytic reactions are abound in the production of oleochemicals: Nickel based catalysts are used in the hydrogenation of unsaturated fatty acids; sodium methylate catalyst in the transesterification of triglycerides; sulfonic based polystyrene resin catalyst in esterification of fatty acids; and copper chromite/copper zinc catalyst in the high pressure hydrogenation of methyl esters or fatty acids to produce fatty alcohols. To maintain long catalyst life, it is crucial to ensure the absence of catalyst poisons and inhibitors in the feed. The preparation methods of nickel and copper chromite catalysts are as follows: precipitation, filtration, drying, and calcinations. Sodium methylate is derived from direct reaction of sodium metal and methanol under inert gas. The sulfonic based polystyrene resin is derived from sulfonation of polystyrene crosslinked with di-vinyl-benzene. © 2007 BCREC UNDIP.

    This textbook is aimed at engineering students who are likely to come across magnetics applications in their professional practice. Whether designing lithography equipment containing ferromagnetic brushes, or detecting defects in aeronautics, some basic knowledge of 21st century magnetism is needed. From the magnetic tape on the pocket credit card to the read head in a personal computer, people run into magnetism in many products. Furthermore, in a variety of disciplines tools of the trade exploit magnetic principles, and many interdisciplinary laboratory research areas cross paths with magnetic phenomena that may seem mysterious to the untrained mind. Therefore, this course offers a broad coverage of magnetism topics encountered more often in this millenium, revealing key concepts on which many practical applications rest. Some traditional subjects in magnetism are discussed in the first half of the book, followed by areas likely to spark the curiosity of those more interested in today’s technological achi...

    Die Entscheidung, einen zeit- bzw. ereignisgesteuerten Ansatz für ein Echtzeitsystem zu verwenden, ist schwierig und sehr weitreichend. Weitreichend vor allem deshalb, weil diese beiden Ansätze mit äußerst unterschiedlichen Kontrollflussabstraktionen verknüpft sind, die eine spätere Migration zum anderen Paradigma sehr schwer oder gar unmöglich machen. Wir schlagen daher die Verwendung einer Zwischendarstellung vor, die unabhängig von der jeweils verwendeten Kontrollflussabstraktion ist. Für diesen Zweck verwenden wir auf Basisblöcken basierende Atomic Basic Blocks (ABB) und bauen darauf ein Werkzeug, den Real-Time Systems Compiler (RTSC) auf, der die Migration zwischen zeit- und ereignisgesteuerten Systemen unterstützt.

    International Nuclear Information System (INIS)

    Basic Principles Simulators have the purpose of teaching general concepts, demonstrating and displaying the fundamental physical processes of a plant. They are used to illustrate theory to students and also to provide a preliminary training to the operators, to aquaint them with the basic dynamic interactions of the various systems during the normal operation of a plant, and to show the consequences of the most important and common transients and malfunctions. Basic principles simulators may vary in size from small desk cabinets to large panels. They represent with a certain detail the nuclear and thermohydraulic part of the plant. The availability of video displays allows to present detailed information about process parameters which are not shown on the control panels. In general the overall plant behaviour is represented well. Limitations are mostly found in the areas of logic and control. (orig./HP)

  16. Basics of aerothermodynamics

    CERN Document Server

    Hirschel, Ernst Heinrich

    2015-01-01

    This successful book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing hypersonic cruise and acceleration vehicles. The book gives a review of the issues of transport of momentum, energy and mass, real-gas effects as well as inviscid and viscous flow phenomena. In this second, revised edition the chapters with the classical topics of aerothermodynamics more or less were left untouched. The access to some single topics of practical interest was improved. Auxiliary chapters were put into an appendix. The recent successful flights of the X-43A and the X-51A indicate that the dawn of sustained airbreathing hypersonic flight now has arrived. This proves that the original approach of the book to put emphasis on viscous effects and the aerothermodynamics of radiation-cooled vehicle surfaces was timely. This second, revised edition even more accentuates these topics. A new, additional chapter treats examples of viscous thermal surface eff...

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction .

    Renewable gases such as biogas and biomethane are considered as key energy carrier when the society is replacing fossil fuels with renewable alternatives. In Sweden, almost 80 % of the fossil fuels are used in the transport sector. Therefore, the focus in Sweden has been to use the produced biogas in this sector as vehicle gas. Basic Data on Biogas contains an overview of production, utilisation, climate effects etc. of biogas from a Swedish perspective. The purpose is to give an easy overview of the current situation in Sweden for politicians, decision makers and interested public. 1.4 TWh of biogas is produced annually in Sweden at approximately 230 facilities. The 135 wastewater treatment plants that produce biogas contribute with around half of the production. In order to reduce the sludge volume, biogas has been produced at wastewater treatment plants for decades. New biogas plants are mainly co-digestion plants and farm plants. The land filling of organic waste has been banned since 2005, thus the biogas produced in landfills is decreasing.

    Full Text Available The goal of grounded theory is to generate a theory that accounts for a pattern of behavior that is relevant and problematic for those involved. The goal is not voluminous description, nor clever verification. As with all grounded theory, the generation of a basic social process (BSP theory occurs around a core category. While a core category is always present in a grounded research study, a BSP may not be.BSPs are ideally suited to generation by grounded theory from qualitative research because qualitative research can pick up process through fieldwork that continues over a period of time. BSPs are a delight to discover and formulate since they give so much movement and scope to the analyst’s perception of the data. BSPs such as cultivating, defaulting, centering, highlighting or becoming, give the feeling of process, change and movement over time. They also have clear, amazing general implications; so much so, that it is hard to contain them within the confines of a single substantive study. The tendency is to refer to them as a formal theory without the necessary comparative development of formal theory. They are labeled by a “gerund”(“ing” which both stimulates their generation and the tendency to over-generalize them.

    In an effort to educate the public about the long road from obscure experiment to life-changing discovery, the National Academy of Sciences (NAS) has been enlisting prominent researchers, science writers, and scientific organizations such as the AGU. More than two years in development, the NAS basic science initiative “Beyond Discovery: The Path From Research to Human Benefits” is an attempt to translate peer-review-quality science papers into general-interest science articles and booklets.As conceived by NAS vice-president Jack Halpern and a host of representatives from the scientific community, the Beyond Discovery initiative will “develop case studies that identify and trace the origins of important technological and medical advances.” These case studies will be written by scientists in a style publishable in a journal such as the Proceedings of the National Academy of Science. The articles are intended to be understandable to educators, college students, and the scientifically literate public. The case studies then will be further distilled by science writers into articles for a wider audience of policy makers and the general public.

The completeness of substitution of carbonate groups for sulfate groups is attained at 30-35% of the precipitator excess. The carbonate number (CO32-:Zr) in the basic carbonate precipitate may be controlled by a proper change of the sulfate number (SO42-:Zr) in the initial product

    2015-01-01

    Mathematics is a powerful tool for describing and developing our knowledge of the physical world. It informs our understanding of subjects as diverse as music, games, science, economics, communications protocols, and visual arts. Mathematical thinking has its roots in the adaptive behavior of living creatures: animals must employ judgments about quantities and magnitudes in the assessment of both threats (how many foes) and opportunities (how much food) in order to make effective decisions, and use geometric information in the environment for recognizing landmarks and navigating environments. Correspondingly, cognitive systems that are dedicated to the processing of distinctly mathematical information have developed. In particular, there is evidence that certain core systems for understanding different aspects of arithmetic as well as geometry are employed by humans and many other animals. They become active early in life and, particularly in the case of humans, develop through maturation. Although these core systems individually appear to be quite limited in application, in combination they allow for the recognition of mathematical properties and the formation of appropriate inferences based upon those properties. In this overview, the core systems, their roles, their limitations, and their interaction with external representations are discussed, as well as possibilities for how they can be employed together to allow us to reason about more complex mathematical domains.

  9. Basic Principles of MLC

    2012-01-01

    Full Text Available Micellar liquid chromatography (MLC is an efficient alternative to conventional reversed-phase liquid chromatography with hydro-organic mobile phases. Almost three decades of experience have resulted in an increasing production of analytical applications. Current concern about the environment also reveals MLC as an interesting technique for “green” chemistry because it uses mobile phases containing 90% or more water. These micellar mobile phases have a low toxicity and are not producing hazardous wastes. The stationary phase is modified with an approximately constant amount of surfactant monomers, and the solubilising capability of the mobile phase is altered by the presence of micelles, giving rise to a great variety of interactions (hydrophobic, ionic, and steric with major implications in retention and selectivity. From its beginnings in 1980, the technique has evolved up to becoming in a real alternative in some instances (and a complement in others to classical RPLC with aqueous-organic mixtures, owing to its peculiar features and unique advantages. The addition of an organic solvent to the mobile phase was, however, soon suggested in order to enhance the low efficiencies and weak elution strength associated with the mobile phases that contained only micelles.

  12. Egalitarianism, basic structure and rawlsian contextualism

    Directory of Open Access Journals (Sweden)

    Cristián Fatauros

    2015-09-01

    Full Text Available This paper analyses whether it is appropriate to judge individual actions with the same principles of justice applicable to institutions. In order to achieve its aim the paper reviews Rawls` theory of justice and some objections against it. Critics of Rawlsian theory of justice deny that its principles only evaluate basic institutions. Furthermore, they claim that justice does not only require just institutions but just individual actions as well. The background hypothesis of this paper is that some principles suitable for some social contexts are not useful to judge other kind of social interactions. The argument relies on a normative interpretation of the notion of basic structure, which is considered a key element to defend the institutional character of the rawlsian account of justice.

  16. The basic aerodynamics of floatation

    Energy Technology Data Exchange (ETDEWEB)

    Davies, M.J.; Wood, D.H.

    1983-09-01

    The original derivation of the basic theory governing the aerodynamics of both hovercraft and modern floatation ovens, requires the validity of some extremely crude assumptions. However, the basic theory is surprisingly accurate. It is shown that this accuracy occurs because the final expression of the basic theory can be derived by approximating the full Navier-Stokes equations in a manner that clearly shows the limitations of the theory. These limitations are used in discussing the relatively small discrepancies between the theory and experiment, which may not be significant for practical purposes.

    2016-01-01

    Based on the latest version of designing codes both for buildings and bridges (GB50010-2010 and JTG D62-2004), this book starts from steel and concrete materials, whose properties are very important to the mechanical behavior of concrete structural members. Step by step, analysis of reinforced and prestressed concrete members under basic loading types (tension, compression, flexure, shearing and torsion) and environmental actions are introduced. The characteristic of the book that distinguishes it from other textbooks on concrete structures is that more emphasis has been laid on the basic theories of reinforced concrete and the application of the basic theories in design of new structures and analysis of existing structures. Examples and problems in each chapter are carefully designed to cover every important knowledge point. As a basic course for undergraduates majoring in civil engineering, this course is different from either the previously learnt mechanics courses or the design courses to be learnt. Compa...

  7. Basic Data of Ionized Gas Physics

    International Nuclear Information System (INIS)

    An ionized gas can a priori contain the following types of particle: photons, electrons, atoms, diatomic or polyatomic molecules, atomic or molecular positive ions and atomic or molecular negative ions. A study of the properties of ionized gases must therefore be based on the fundamental data on the interactions between these particles, i.e. elastic or inelastic collision cross-sections and the probability of induced or spontaneous transitions. From these basic data it is possible to calculate theoretically certain elementary macroscopic properties such as ion and electron mobility, diffusion coefficients, Townsend's first coefficient, recombination and attachment coefficients. These results (cross-sections and elementary macroscopic properties) constitute as a body the basic data for the physics of ionized gases. The paper is devoted to these basic data, concentrating on cross-sections, mobilities and diffusion coefficients. Beginning with a brief review of the literature, it consists essentially of tables of suggested numerical values, which the author intends to be used as a basis for discussion. Experts in each of the phenomena are invited to indicate values which seem to them better than those selected, and to fill in, where possible, the gaps in this study. In this way it is hoped that by the next Conference a more precise and more complete collection of data will be available. (author)

    Science.gov (United States)

    Davies, M. J.; Wood, D. H.

    1983-09-01

    It is pointed out that the basic aerodynamics of modern floatation ovens, in which the continuous, freshly painted metal strip is floated, dried, and cured, is the two-dimensional analog of that of hovercraft. The basic theory for the static lift considered in connection with the study of hovercraft has had spectacular success in describing the experimental results. This appears surprising in view of the crudity of the theory. The present investigation represents an attempt to explore the reasons for this success. An outline of the basic theory is presented and an approach is shown for deriving the resulting expressions for the lift from the full Navier-Stokes equations in a manner that clearly indicates the limitations on the validity of the expressions. Attention is given to the generally good agreement between the theory and the axisymmetric (about the centerline) results reported by Jaumotte and Kiedrzynski (1965).

    The basic space science initiative was a long-term effort for the development of astronomy and space science through regional and international cooperation in this field on a worldwide basis, particularly in developing nations. Basic space science workshops were co-sponsored and co-organized by ESA, JAXA, and NASA. A series of workshops on basic space science was held from 1991 to 2004 (India 1991, Costa Rica and Colombia 1992, Nigeria 1993, Egypt 1994, Sri Lanka 1995, Germany 1996, Honduras 1997, Jordan 1999, France 2000, Mauritius 2001, Argentina 2002, and China 2004; http://neutrino.aquaphoenix.com/un-esa/) and addressed the status of astronomy in Asia and the Pacific, Latin America and the Caribbean, Africa, and Western Asia. Through the lead of the National Astronomical Observatory Japan, astronomical telescope facilities were inaugurated in seven developing nations and planetariums were established in twenty developing nations based on the donation of respective equipment by Japan.Pursuant to resolutions of the Committee on the Peaceful Uses of Outer Space of the United Nations (COPUOS) and its Scientific and Technical Subcommittee, since 2005, these workshops focused on the preparations for and the follow-ups to the International Heliophysical Year 2007 (UAE 2005, India 2006, Japan 2007, Bulgaria 2008, South Korea 2009; www.unoosa.org/oosa/SAP/bss/ihy2007/index.html). IHY's legacy is the current operation of 16 worldwide instrument arrays with more than 1000 instruments recording data on solar-terrestrial interaction from coronal mass ejections to variations of the total electron content in the ionosphere (http://iswisecretariat.org/). Instruments are provided to hosting institutions by entities of Armenia, Brazil, France, Israel, Japan, Switzerland, and the United States.

The book is divided into two main parts: Deterministic methods and stochastic methods in computational physics. Based on concrete problems, the first part discusses numerical differentiation and integration, as well as the treatment of ordinary differential equations. This is extended by a brief introduction to the numerics of partial differential equations. The second part deals with the generation of random numbers, summarizes the basics of stochastics, and subsequently introduces Monte-Carlo (MC) methods. Specific emphasis is on MARKOV chain MC algorithms. The final two chapters discuss data analysis and stochastic optimization. All this is again motivated and augmented by applications from physics. In addition, the book offers a number of appendices to provide the read...

  15. Basic statistics in cell biology.

    Science.gov (United States)

    Vaux, David L

    2014-01-01

    The physicist Ernest Rutherford said, "If your experiment needs statistics, you ought to have done a better experiment." Although this aphorism remains true for much of today's research in cell biology, a basic understanding of statistics can be useful to cell biologists to help in monitoring the conduct of their experiments, in interpreting the results, in presenting them in publications, and when critically evaluating research by others. However, training in statistics is often focused on the sophisticated needs of clinical researchers, psychologists, and epidemiologists, whose conclusions depend wholly on statistics, rather than the practical needs of cell biologists, whose experiments often provide evidence that is not statistical in nature. This review describes some of the basic statistical principles that may be of use to experimental biologists, but it does not cover the sophisticated statistics needed for papers that contain evidence of no other kind.

    OpenAIRE

    Shortliffe, Edward H.

    1980-01-01

    Medical computing is frequently viewed as the application of established computer science techniques in medical domains. However, it is the thesis of this paper that many clinical computing tasks demand techniques that are as yet undeveloped. As a result, medical computing research should logically be closely tied to basic research in computer science. Failure to recognize that this developing discipline often requires fundamental investigation has tended to foster unrealistic expectations of...

  3. [Basic research overview in rheumatoid arthritis].

    Science.gov (United States)

    Iwasaki, Yukiko; Yamamoto, Kazuhiko

    2016-06-01

    Rheumatoid arthritis (RA) is a common autoimmune disease with a prevalence of 0.5-1.0% worldwide. Although advances in understanding the pathogenesis of RA have led to new therapeutics with good outcomes, the real cause of the disease is still unknown. RA is characterized by synovial inflammation and hyperplasia, which erodes cartilage and bone, and autoantibody production (rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA)). There are many critical questions on the mechanism of the disease onset and progression: How genetic and environmental factors interact with each other? Why does the inflammatory response localize in joints? What are the key players to perpetuate synovial inflammation? In this review, we summarize pathogenetic advances in these issues especially from the point of view of basic research.

  4. Study on Basic Mechanism of Reactive Armour

    Directory of Open Access Journals (Sweden)

    H. S. Yadav

    1995-07-01

    Full Text Available Two basic mechanisms which operate in the functioning of reactive armour are presented. Both the explosive effect and cutting of metal plates by a jet have been investigated. The angle of attack and the confinement of the explosive have been found most significant factors in reducing the penetrating power of the jet. The effect of detonating explosives has been investigated with radiography. Some of the significant effects, like detonation of explosive by the impact of the jet, expansion of covering plates, disturbance in coherence and reduction in the penetration of the jet have been observed. It is found that the jet penetration in a stack of mild steel plates is reduced to 30 per cent of its blank penetration in present set-ups. A theoretical model has been conceived to study the interaction of moving plates and the jet. The critical thickness and surface cut in plates have been calculated.

  5. Colloidal Plasmas : Basic physics of colloidal plasmas

    Indian Academy of Sciences (India)

    C B Dwivedi

    2000-11-01

    Colloidal plasma is a distinct class of the impure plasmas with multispecies ionic composition. The distinction lies in the phase distribution of the impurity-ion species. The ability to tailor the electrostatic interactions between these colloidal particles provides a fertile ground for scientists to investigate the fundamental aspects of the Coulomb phase transition behavior. The present contribution will review the basic physics of the charging mechanism of the colloidal particles as well as the physics of the collective normal mode behavior of the general multi-ion species plasmas. Emphasis will be laid on the clarification of the prevailing confusing ideas about distinct qualities of the various acoustic modes, which are likely to exist in colloidal plasmas as well as in normal multi-ion species plasmas. Introductory ideas about the proposed physical models for the Coulomb phase transition in colloidal plasma will also be discussed.

    In this study, changes from past to present in the departments of physics, chemistry, biology and mathematics, which are considered as the basic sciences in Turkey, are shown. The importance of basic science for the country emphasized and the status of our country was discussed with a critical perspective. The number of academic staff, the number of students, opened quotas according to years for these four departments at universities were calculated and analysis of the resulting changes were made. In examined graphics changes to these four departments were similar. Especially a significant change was observed in the physics department. Lack of jobs employing young people who have graduated from basic science is also an issue that must be discussed. There are also qualitative results of this study that we have discussed as quantitative. Psychological problems caused by unemployment have become a disease among young people. This study was focused on more quantitative results. We have tried to explain the causes of obtained results and propose solutions.

    International Nuclear Information System (INIS)

    Teollisuuden Voima Oy (TVO) has carried out research into basic rock types in Finland. The research programme has been implemented in parallel with the preliminary site investigations for radioactive waste disposal in 1991-1993. The program contained two main objectives: firstly, to study the properties of the basic rock types and compare those with the other rock types under the investigation; secondly, to carry out an inventory of rock formations consisting of basic rock types and suitable in question for final disposal. A study of environmental factors important to know regarding the final disposal was made of formations identified. In total 159 formations exceeding the size of 4 km2 were identified in the inventory. Of these formations 97 were intrusive igneous rock types and 62 originally extrusive volcanic rock types. Deposits consisting of ore minerals, industrial minerals or building stones related to these formations were studied. Environmental factors like natural resources, protected areas or potential for restrictions in land use were also studied

    1994-01-01

    The Basic Linear Algebra Subprogram (BLAS) library is a collection of FORTRAN callable routines for employing standard techniques in performing the basic operations of numerical linear algebra. The BLAS library was developed to provide a portable and efficient source of basic operations for designers of programs involving linear algebraic computations. The subprograms available in the library cover the operations of dot product, multiplication of a scalar and a vector, vector plus a scalar times a vector, Givens transformation, modified Givens transformation, copy, swap, Euclidean norm, sum of magnitudes, and location of the largest magnitude element. Since these subprograms are to be used in an ANSI FORTRAN context, the cases of single precision, double precision, and complex data are provided for. All of the subprograms have been thoroughly tested and produce consistent results even when transported from machine to machine. BLAS contains Assembler versions and FORTRAN test code for any of the following compilers: Lahey F77L, Microsoft FORTRAN, or IBM Professional FORTRAN. It requires the Microsoft Macro Assembler and a math co-processor. The PC implementation allows individual arrays of over 64K. The BLAS library was developed in 1979. The PC version was made available in 1986 and updated in 1988.

    The Food and Agriculture Organization (FAO) predicts that food production must rise 70% over the next 40 years to meet the demands of a growing population that is expected to reach nine billion by the year 2050. Many facets of basic plant science promoted by the Botanical Society of America are important for agriculture; however, more explicit connections are needed to bridge the gap between basic and applied plant research. This special issue, Speaking of Food: Connecting Basic and Applied Plant Science, was conceived to showcase productive overlaps of basic and applied research to address the challenges posed by feeding billions of people and to stimulate more research, fresh connections, and new paradigms. Contributions to this special issue thus illustrate some interactive areas of study in plant science-historical and modern plant-human interaction, crop and weed origins and evolution, and the effects of natural and artificial selection on crops and their wild relatives. These papers provide examples of how research integrating the basic and applied aspects of plant science benefits the pursuit of knowledge and the translation of that knowledge into actions toward sustainable production of crops and conservation of diversity in a changing climate.

    The Basic Radar Altimetry Toolbox is an "all-altimeter" collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data, including the last mission launched, CryoSat. It has been available from April 2007, and had been demonstrated during training courses and scientific meetings. Nearly 1200 people downloaded it (as of end of June 2010), with many "newcomers" to altimetry among them. Users' feedbacks, developments in altimetry, and practice, showed that new interesting features could be added. Some have been added and/or improved in version 2. Others are ongoing, some are in discussion. The Basic Radar Altimetry Toolbox is able: - to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason- 1, Envisat, Jason- 2, CryoSat and also the future Saral and Sentinel 3 missions, - to perform some processing, data editing and statistic, - and to visualize the results. It can be used at several levels/several ways: - as a data reading tool, with APIs for C, Fortran, Matlab and IDL - as processing/extraction routines, through the on-line command mode - as an educational and a quick-look tool both, with the graphical user interface As part of the Toolbox, a Radar Altimetry Tutorial gives general information about altimetry, the technique involved and its applications, as well as an overview of past, present and future missions, including information on how to access data, additional software and documentation. It also presents a series of data use cases, covering all uses of altimetry over ocean, cryosphere and land, showing the basic methods for some of the most frequent manners of using altimetry data. BRAT is developed under contract with ESA and CNES. It is available at http://www.altimetry.info and http://earth.esa.int/brat/

    A lecture was presented by the author at the Democratic Opinion Forum on Health Teaching and Research, organized by Mexico's National Health Institutes Coordinating Office, at National Cardiology Institute "Ignacio Chavez", where he presented a critical review of the conventional classification of basic and applied science, as well as his personal view on health science teaching and research. According to the author, "well-conducted science" is that "generating reality-checked knowledge" and "mis-conducted science" is that "unproductive or producing 'just lies' and 'non-fundable'. To support his views, the author reviews utilitarian and pejorative definitions of science, as well as those of committed and pure science, useful and useless science, and practical and esoterical science, as synonyms of applied and basic science. He also asserts that, in Mexico, "this classification has been used in the past to justify federal funding cutbacks to basic science, allegedly because it is not targeted at solving 'national problems' or because it was not relevant to priorities set in a given six-year political administration period". Regarding health education and research, the author asserts that the current academic programs are inefficient and ineffective; his proposal to tackle these problems is to carry out a solid scientific study, conducted by a multidisciplinary team of experts, "to design the scientific researcher curricula from recruitment of intelligent young people to retirement or death". Performance assessment of researchers would not be restricted to publication of papers, since "the quality of scientific work and contribution to the development of science is not reflected by the number of published papers".

    A one-dimensional model of the virtual cathode oscillator (vircator) is proposed keeping only the essential physical processes. The basic model consists of a radiating charge in an oscillating electric field. Using parameters from (realistic) particle-in-cell simulations such as the charge Q and amplitude E1 of the oscillating electric field, the model correctly predicts the amplitude of virtual cathode oscillation and the power radiated. The basic model is then extended to incorporate beam-cavity interaction and the resonance effect.

    The Gaia mission1 will create an extraordinarily precise three-dimensional map of more than one billion stars in our Galaxy. The Gaia spacecraft2, built by EADS Astrium, is part of ESA's Cosmic Vision programme and scheduled for launch in 2013. Gaia measures the position, distance and motion of stars with an accuracy of 24 micro-arcsec using two telescopes at a fixed mutual angle of 106.5°, named the `Basic Angle', at an operational temperature of 100 K. This accuracy requires ultra-high stability at cryogenic conditions, which can only be achieved by using Silicon Carbide for both the optical bench and the telescopes. TNO has developed, built and space qualified the Silicon carbide Basic Angle Monitoring (BAM) on-board metrology system3 for this mission, measuring the relative motion of Gaia's telescopes with accuracies in the range of 0.5 micro-arcsec. This is achieved by a system of two laser interferometers able to detect Optical Path Differences (OPD) as small as 1.5 picometer rms. Following a general introduction on Gaia and the use of Silicon Carbide as base material this paper addresses the specific challenges towards the cryogenic application of the Gaia BAM including design, integration and verification/qualification by testing.

    Full Text Available Digital Storytelling (DST is a powerful tool for teaching complex concepts. DSTs are typically used in the humanities but several papers have shown that they are also a wonderful tool for the sciences because they are more involving, contextualized and can easily lead to deeper understanding. In the classical use of DST the story is thecontent, while the digital medium is the way of telling it. Our approach is slightly different: the story is not the content but a glue for the main contents, while the digital medium remains the way to tell the story. We propose the use of DST as a means to teach surgeons the basics of robotic surgery, by using a story that should be involving forthem, i.e. a surgical operation, within which we will illustrate specific concepts onrobotics in surgery.

    1992-03-09

    PC-BLAS is a highly optimized version of the Basic Linear Algebra Subprograms (BLAS), a standardized set of thirty-eight routines that perform low-level operations on vectors of numbers in single and double-precision real and complex arithmetic. Routines are included to find the index of the largest component of a vector, apply a Givens or modified Givens rotation, multiply a vector by a constant, determine the Euclidean length, perform a dot product, swap and copy vectors, and find the norm of a vector. The BLAS have been carefully written to minimize numerical problems such as loss of precision and underflow and are designed so that the computation is independent of the interface with the calling program. This independence is achieved through judicious use of Assembly language macros. Interfaces are provided for Lahey Fortran 77, Microsoft Fortran 77, and Ryan-McFarland IBM Professional Fortran.

At the same time that we are being presented with more options for diagnosis and treatment, governments around the world are fighting to reduce deficit spending and inflation. As a direct result of this combination of reduced spending and increased options for care, medical professionals are being asked to provide more effective care more efficiently. The randomized control trial may be the best way to determine the effectiveness of different options, however, only a full economic analysis can help decide which option is more efficient. This paper is intended to provide the reader with a basic understanding of the methods used to perform a full economic analysis.

  11. Basic Energy Research. Final Report

    International Nuclear Information System (INIS)

    This is the final report of a research programme that covered the need for long-term basic research in Norway within the main fields of new renewable energy sources and hydroelectric power. For the hydropower part, emphasis was placed on the environmental consequences and several projects have been done, with different approaches. Other aspects of hydropower have also been supported, such as dam safety and flow in water paths connected to turbines. Within the field of renewable energies, priority was given to solar energy and bio energy. Research on hydrogen as an energy carrier has also been supported; the programme mainly targeted universities and the research institutes, and the education of PhD's has been a priority. The programme was funded through the Ministry of Petroleum and Energy and the budget was 33 million NOK for the period 1997 - 2000

    2010-01-01

    These are Lecture Notes of a course given by the author at the French-Spanish School "Tresses in Pau", held in Pau (France) in October 2009. It is basically an introduction to distinct approaches and techniques that can be used to show results in braid groups. Using these techniques we provide several proofs of well known results in braid groups, namely the correctness of Artin's presentation, that the braid group is torsion free, or that its center is generated by the full twist. We also recall some solutions of the word and conjugacy problems, and that roots of a braid are always conjugate. We also describe the centralizer of a given braid. Most proofs are classical ones, using modern terminology. I have chosen those which I find simpler or more beautiful.

  13. Basic research on maxillofacial implants

    Energy Technology Data Exchange (ETDEWEB)

    Matsui, Yoshiro [Showa Univ., Tokyo (Japan). School of Dentistry

    2001-11-01

    Osseointegrated implants have begun to be used not only in general practice in dentistry but also in various clinical situations in the maxillofacial region. The process has yielded three problems: the spread of application, new materials and diagnostic methods, and management for difficult situations. This paper presents basic data and clinical guidelines for new applications, it investigates the characteristics of the materials and the usefulness of a new diagnostic method, and it studies effective techniques for difficult cases. The results obtained are as follows: Investigations into the spreading application. The lateral and superior orbital rim have sufficient bone thickness and width for the implant body to be placed. Osseointegrated implants, especially by the fixed bridge technique, are not recommended in the craniofacial bone and jaws of young children. Implant placement into bone after/before irradiation must be performed in consideration of impaired osteogenesis, the decrease of trabecular bone, and the time interval between implantation and irradiation. Investigations into materials and diagnostic methods. Hydroxyapatite-coated and titanium implants should be selected according to the characteristics of the materials. A dental simulating soft may also be applicable in the craniofacial region. Investigations into the management of difficult cases. Hyperbaric oxygen therapy (HBO), bone morphogenetic protein (BMP), and tissue engineering should be useful for improving the quality and increasing the quantity of bone where implants are placed. Soft tissue around implants placed in the reconstructed area should be replaced with mucosal tissue. The data obtained here should be useful for increasing the efficiency of osseointegrated implants, but further basic research is required in the future. (author)

  14. Psychometrics in Psychiatry: Basic Concepts

    Directory of Open Access Journals (Sweden)

    Hüseyin Gülec

    2009-09-01

    Full Text Available Understanding human mental process as a natural event is the mainstay for positive science. Measurement or scaling these processes is the basic component of positive science. If we call the science of psychometrics as “mind measuring”, then the scales should be remarked as the tools of “mind meter”. Besides, if science is considered as a play in which your assertions are only within the limit of your measurements, and then the book of rules ought to be written precisely and updated regularly. In the history of science, there are many incidents in which different tools which had been marked to measure several variables or things were later found to be unable to implement the measurement it had been assigned. Thus the book of rules should set the boundaries of measurements, where to start and to finish, by preventing any confounding factors. Validity and especially construct validity of the scales set the basic conceptual framework. But, positive science should present the proof of reliability before providing the validity. Reliability –how you measure- is considered to put an upper limit on validity because any problem in reliability makes it harder to detect a valid “signal”. Another important step in measurement is to apply same directives to all participants to assure standardization. Thereby, we could ensure that the entire world keep same standard in the evaluation and application of the scale. Other process is to obtain normative value according to related variables in order to prevent confounding possible cultural factors. All of these steps has been comprised under the title of standardization. With this article, we would like to make sense to the reader concerning what is meant by psychometric properties of scales and focus on the process of standardization and its components.

  1. Chasing Ecological Interactions

    Science.gov (United States)

    2016-01-01

    Basic research on biodiversity has concentrated on individual species—naming new species, studying distribution patterns, and analyzing their evolutionary relationships. Yet biodiversity is more than a collection of individual species; it is the combination of biological entities and processes that support life on Earth. To understand biodiversity we must catalog it, but we must also assess the ways species interact with other species to provide functional support for the Tree of Life. Ecological interactions may be lost well before the species involved in those interactions go extinct; their ecological functions disappear even though they remain. Here, I address the challenges in studying the functional aspects of species interactions and how basic research is helping us address the fast-paced extinction of species due to human activities.

  7. Virtual cathode microwave devices -- Basics

    Energy Technology Data Exchange (ETDEWEB)

    Thode, L.E.; Snell, C.M.

    1991-01-01

    Unlike a conventional microwave tube, a virtual-cathode device operates above the space-charge limit where the depth of the space-charge potential can cause electron reflection. The region associated with this electron reflection is referred to as a virtual cathode. Microwaves can be generated through oscillations in the position of the virtual cathode and through the bunching of electrons trapped in a potential well between the real and virtual cathodes. These two mechanisms are competitive. There are three basic classes of virtual cathode devices: (1) reflex triode; (2) reditron and side-shoot vircator; and (3) reflex diode or vircator. The reflex diode is the highest power virtual-cathode device. For the reflex diode the energy exchange between the beam and electromagnetic wave occurs in both the axial and radial directions. In some designs the oscillating-virtual-cathode frequency exceeds the reflexing-electron frequency exceeds the oscillating-virtual-cathode frequency. For the flex diode a periodic disruption in magnetic insulation can modulate the high- frequency microwave power. Overall, particle-in-cell simulation predictions and axial reflex diode experiments are in good agreement. Although frequency stability and phase locking of the reflex diode have been demonstrated, little progress has been made in efficiency enhancement. 58 refs., 11 figs.

    The U.S. Department of Energy’s (DOE) Office of Basic Energy Sciences (BES) supports fundamental research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels to provide the foundations for new energy technologies and to support DOE missions in energy, environment, and national security. The research disciplines covered by BES—condensed matter and materials physics, chemistry, geosciences, and aspects of physical biosciences— are those that discover new materials and design new chemical processes. These disciplines touch virtually every aspect of energy resources, production, conversion, transmission, storage, efficiency, and waste mitigation. BES also plans, constructs, and operates world-class scientific user facilities that provide outstanding capabilities for imaging and spectroscopy, characterizing materials of all kinds ranging from hard metals to fragile biological samples, and studying the chemical transformation of matter. These facilities are used to correlate the microscopic structure of materials with their macroscopic properties and to study chemical processes. Such experiments provide critical insights to electronic, atomic, and molecular configurations, often at ultrasmall length and ultrafast time scales.

  11. [Psychophysiology as a basic science in psychiatry].

    Science.gov (United States)

    Lolas, F

    1984-09-01

    A characterization of psychophysiology as a psychiatric basic science is presented. Based upon the methodical pluralism of an open anthropology, this discipline must provide a unifying framework of different methodological strategies and the patterns of thought needed for their armonic integration. Its aim is the generation of "neutral" constructs and theories with meaning in different discourses. This implies to recognize and accept the contextualism of every empirical knowledge and poses the problem of the complementary of different approaches. The different levels of analysis in which the relationships between the nervous system and behavior are studied allow the distinction between two forms of objectivity: the objectivity of the physiological processes and the objectivity of subjective functions. Among these, two are discussed; estesiologic subjectivity, based upon the perception of the own body, and dialogic interaction, derived from bodily expression and communication. The need for studies across different levels of analysis affords the opportunity to employ different models of thought to approach the same problems and to identify mechanisms and emergent properties in the systems studied.

  12. Creating conditions for cooperative learning: Basic elements

    Directory of Open Access Journals (Sweden)

    Ševkušić-Mandić Slavica G.

    2003-01-01

    Full Text Available Although a large number of research evidence speak out in favor of cooperative learning, its effectiveness in teaching does not depend only on teacher’s and students’ enthusiasm and willingness to work in such a manner. Creating cooperative situations in learning demands a serious preparation and engagement on the part of teacher who is structuring various aspects of work in the classroom. Although there exist a large number of models and techniques of cooperative learning, which vary in the way in which students work together, in the structure of learning tasks as well as in the degree to which cooperative efforts of students are coupled with competition among groups, some elements should be present in the structure of conditions irrespective of the type of group work in question. Potential effects of cooperation are not likely to emerge unless teachers apply five basic elements of cooperative structure: 1. structuring of the learning task and students’ positive interdependence, 2. individual responsibility, 3. upgrading of "face to face" interaction, 4. training of students’ social skills, and 5. evaluation of group processes. The paper discusses various strategies for establishing the mentioned elements and concrete examples for teaching practice are provided, which should be of assistance to teachers for as much successful cooperative learning application as possible in work with children.

    Cesium is a major nuclear fission product which is volatile and corrosive and it is able to interact with fuels, cladding tubes and/or other fission products resulting in productions of various compounds. The presence of those compounds may give rise to physical and chemical interactions between fuels and the cladding tube, resulting in changes in their heat transfer coefficients. In this study, some cesium uranates were prepared in the laboratory. Then, Cs{sub 2}UO{sub 4}, Cs{sub 2}U{sub 2}O{sub 7} and Cs{sub 2}U{sub 4}O{sub 12} were thermodynamically analyzed by phase equilibrium calculation using the calculation code, CHEMSAGE. And physicochemical properties of these compounds were investigated. The reaction conditions for producing the three compounds were determined. The equilibrium diagram revealed that Cs{sub 2}UO{sub 4} is stable in a wider range for the partial pressures of oxygen and cesium than Cs{sub 2}U{sub 2}O{sub 7} or Cs{sub 2}U{sub 4}O{sub 12}. Some orange colored product was obtained from the reaction of Cs{sub 2}CO{sub 3} and U{sub 3}O{sub 8} in an electric furnace and Cs{sub 2}U{sub 2}O{sub 7} but not Cs{sub 2}UO{sub 4} was identified by X-ray diffraction of the product.

  14. Basics of acute stroke treatment

    International Nuclear Information System (INIS)

    Acute stroke presents an emergency that requires immediate referral to a specialized hospital, preferably with a stroke unit. Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward. Systolic blood pressure may remain high at 200-220 mmHg in the acute phase and should not be lowered too quickly. Further guidelines for basic care include: optimal O2 delivery, blood sugar levels below 100-150 mg%, and lowering body temperature below 37.5 C using physical means or drugs. Increased intracranial pressure should be treated by raising the upper body of the patient, administration of glycerol, mannitol, and/or sorbitol, artificial respiration, and special monitoring of Tris buffer. Decompressive craniectomy may be considered in cases of ''malignant'' media stroke and expansive cerebellar infarction. Fibrinolysis is the most effective stroke treatment and is twice as effective in the treatment of stroke than myocardial infarction. Fibrinolysis may be initiated within 3 h of a stroke in the anterior circulation. If a penumbra is detectable by ''PWI-DWI mismatch MRI,'' specialized hospitals may perform fibrinolysis up to 6 h after symptom onset. In cases of stroke in the basilar artery, fibrinolysis may be performed even later after symptom onset. Intra-arterial fibrinolysis is performed in these cases using rt-PA or urokinase. Follow-up treatment of stroke patients should not only address post-stroke depression and neuropsychological deficits, but also include patient education about risk factors such as high blood pressure, diabetes mellitus, and cardiac arrhythmias.

    Haker, Helene; Schimansky, Jenny; Rössler, Wulf

    2010-01-01

    The aim of this review is to describe sociophysiological and social cognitive processes that underlie the complex phenomenon of human empathy. Automatic reflexive processes such as physiological contagion and action mirroring are mediated by the mirror neuron system. They are a basis for further processing of social signals and a physiological link between two individuals. This link comprises simultaneous activation of shared motor representations. Shared representations lead implicitly via individual associations in the limbic and vegetative system to a shared affective state. These processes are called sociophysiology. Further controlled- reflective, self-referential processing of those social signals leads to explicit, conscious representations of others' minds. Those higher-order processes are called social cognition. The interaction of physiological and cognitive social processes lets arise the phenomenon of human empathy. PMID:20926053

  9. Linking basic variables to binary data world

    International Nuclear Information System (INIS)

    Personal microcomputers have gained unprecedented popularity thanks to the BASIC language handiness. Its use in small data acquisition system encounters, however, two main drawbacks. The first concerns the slow response of the BASIC interpreter implemented in these small systems; the second is due to a very poor communication between the BASIC world and the machine-coded world. All BASIC symbols for variables, arrays or strings which are so easy to handle, remain unknown to the acquisition machine-language program. Moreover, complex mathematical expressions needed for, say, some non linear correction or control, could be managed in BASIC but would be painful to program even in Assembler's language. This paper shows that, using the dynamical variable pointer, one can implement a natural link between the two worlds, allowing powerful features to BASIC's interpreter in data acquisition systems. In particular, A) A machine coded program written for data logging can get access to BASIC variables and directly transfers data to them without suffering interpreters slow speed. BASIC programs just use them as any other variables. B) A manifold user's call, giving control to different machine coded programs without having to change the user's address as usual. (orig.)

    Schüler, Julia; Wegner, Mirko; Knechtle, Beat

    2014-06-01

    Previous research has shown that the effects of basic psychological needs on the flow experience in sports are moderated by implicit motives. However, so far, only leisure and health-oriented sports have been analyzed. In a pilot study and a main study (N = 29, 93), we tested whether the implicit achievement and affiliation motives interact with the need for competence and the need for social relatedness satisfaction, respectively, to predict flow experience and well-being in extreme endurance athletes. Results showed that highly achievement-motivated individuals benefited more from the need for competence satisfaction in terms of flow than individuals with a low achievement motive did. In addition, highly affiliation-motivated individuals whose need for social relatedness is satisfied reported higher positive affect and lower exercise addiction scores than athletes with a low motive. We discuss the differential effects of the interplay between the achievement and affiliation motives and basic needs on different outcome variables.

    Full Text Available Active learning, project-based teaching, and student collaboration are current trends in engineering education. Incorporating these have also been the goal of the basic studies development project EPOP started at the Aalto University School of Electrical Engineering in 2011. In the project, two obligatory basic courses in circuit analysis and electromagnetic field theory have been taught using interactive engagement during the spring of 2012. This paper presents the implementation of the teaching, including methods and evaluation with several concrete examples. As a result of the novel teaching, motivation and the engagement of students were at a high level during the whole course and learning results were better than those of the students participating the traditional lecture course.

  2. Dimensional psychiatry: mental disorders as dysfunctions of basic learning mechanisms.

    Science.gov (United States)

    Heinz, Andreas; Schlagenhauf, Florian; Beck, Anne; Wackerhagen, Carolin

    2016-08-01

    It has been questioned that the more than 300 mental disorders currently listed in international disease classification systems all have a distinct neurobiological correlate. Here, we support the idea that basic dimensions of mental dysfunctions, such as alterations in reinforcement learning, can be identified, which interact with individual vulnerability and psychosocial stress factors and, thus, contribute to syndromes of distress across traditional nosological boundaries. We further suggest that computational modeling of learning behavior can help to identify specific alterations in reinforcement-based decision-making and their associated neurobiological correlates. For example, attribution of salience to drug-related cues associated with dopamine dysfunction in addiction can increase habitual decision-making via promotion of Pavlovian-to-instrumental transfer as indicated by computational modeling of the effect of Pavlovian-conditioned stimuli (here affectively positive or alcohol-related cues) on instrumental approach and avoidance behavior. In schizophrenia, reward prediction errors can be modeled computationally and associated with functional brain activation, thus revealing reduced encoding of such learning signals in the ventral striatum and compensatory activation in the frontal cortex. With respect to negative mood states, it has been shown that both reduced functional activation of the ventral striatum elicited by reward-predicting stimuli and stress-associated activation of the hypothalamic-pituitary-adrenal axis in interaction with reduced serotonin transporter availability and increased amygdala activation by aversive cues contribute to clinical depression; altogether these observations support the notion that basic learning mechanisms, such as Pavlovian and instrumental conditioning and Pavlovian-to-instrumental transfer, represent a basic dimension of mental disorders that can be mechanistically characterized using computational modeling and

    In 1977 Grünbaum and Shephard described all possible 93 types of isohedral marked tilings of the plane; 46 of them are called basic, since their induced tile group is trivial. The aim of this paper is to give an algebraic description of all basic tilings. A purely algebraic characterization of the adjacency symmetries of tiles of the 46 basic tilings is presented. Moreover, 46 related abstract definitions of two-dimensional crystallographic groups supplement and extend those of the well-known book Generators and Relations for Discrete Groups by Coxeter and Moser.

  8. Theory of fundamental interactions

    International Nuclear Information System (INIS)

    In the present article the theory of fundamental interactions is derived in a systematic way from the first principles. In the developed theory there is no separation between space-time and internal gauge space. Main equations for basic fields are derived. In is shown that the theory satisfies the correspondence principle and gives rise to new notions in the considered region. In particular, the conclusion is made about the existence of particles which are characterized not only by the mass, spin, charge but also by the moment of inertia. These are rotating particles, the particles which represent the notion of the rigid body on the microscopical level and give the key for understanding strong interactions. The main concepts and dynamical laws for these particles are formulated. The basic principles of the theory may be examined experimentally not in the distant future. 29 refs

    2013-08-01

    Represents the first book on non-traditional resonance effects of excitons in semiconductors. Explains resonance phenomena of excitons and electrons in solids. Presents the Knight shift at the Bose-Einstein condensation of excitons. This book presents the various types of resonance effects on excitons, biexcitons and the local electronic centers (LEC) in solids, such as paramagnetic and paraelectric resonances on excitons, exciton acoustic resonance at intra- and interband transitions, radio-optical double resonance on excitons, hole-nuclear double resonance on localized biexcitons, ENDOR and acoustic ENDOR on LEC. The criteria for the generation of coherent photons, phonons and magnons by excitons are explained. The interactions of excitons and biexcitons with paramagnetic centers and nuclear spins, the indirect interaction between the PC through a field of excitons as well as the quasienergy spectrum of excitons and spin systems are discussed. It is proved that the interaction of paramagnetic centers with excitons increases the spin relaxation rate of paramagnetic centers in comparison with the case of their interaction with free carriers. The giant magneto-optical effects in semi-magnetic semiconductors are theoretically interpreted. In recent years, a new perspective has been added to these systems and their interactions: they can be used for storing and processing information in the form of quantum bits (qubits), the building blocks of quantum computers. The basics of this emerging technology are explained and examples of demonstration-type quantum computers based on localized spins in solids are discussed.

  16. Romantic adult attachment and basic personality structure

    Directory of Open Access Journals (Sweden)

    Jelena Zeleskov Djoric

    2012-03-01

    Full Text Available The main goal of this study was localization of attachment dimensions in the space described by basic personality traits. Study purported to examine relations between attachment and basic personality structure, in a sample of 203 respondents. Romantic adult attachment was measured by the Experience in Close Relationship Scale, basic personality structure was assessed by the NEO-PI-R personality inventory, and Disintegration, which represents operationalization of Schizotypy as a basic personality trait, was estimated by the Delta 10 test. The results of Principal component analysis showed that attachment dimensions are not separate constructs in relation to basic personality traits. Furthermore, results indicate that attachment dimensions represent emotional dysregulation in close interpersonal relationships, because positive correlations are found between dimensions of Attachment and Mania (.35, Anxiety (.51 and Depression (.55. Negative correlations have been obtained between Attachment and Positive emotions (-.34 and Feelings (-.31. These results suggest that Attachment dimensions should be considered as an expression of basic personality traits in romantic adult's relationships.

  17. Optical properties of metallic nanoparticles basic principles and simulation

    CERN Document Server

    Trügler, Andreas

    2016-01-01

    This book introduces the fascinating world of plasmonics and physics at the nanoscale, with a focus on simulations and the theoretical aspects of optics and nanotechnology. A research field with numerous applications, plasmonics bridges the gap between the micrometer length scale of light and the secrets of the nanoworld. This is achieved by binding light to charge density oscillations of metallic nanostructures, so-called surface plasmons, which allow electromagnetic radiation to be focussed down to spots as small as a few nanometers. The book is a snapshot of recent and ongoing research and at the same time outlines our present understanding of the optical properties of metallic nanoparticles, ranging from the tunability of plasmonic resonances to the ultrafast dynamics of light-matter interaction. Beginning with a gentle introduction that highlights the basics of plasmonic interactions and plasmon imaging, the author then presents a suitable theoretical framework for the description of metallic nanostructu...

  19. Basic reactions of osteoblasts on structured material surfaces

    Directory of Open Access Journals (Sweden)

    B�chter A.

    2005-04-01

    Full Text Available In order to assess how bone substitute materials determine bone formation in vivo it is useful to understand the mechanisms of the material surface/tissue interaction on a cellular level. Artificial materials are used in two applications, as biomaterials alone or as a scaffold for osteoblasts in a tissue engineering approach. Recently, many efforts have been undertaken to improve bone regeneration by the use of structured material surfaces. In vitro studies of bone cell responses to artificial materials are the basic tool to determine these interactions. Surface properties of materials surfaces as well as biophysical constraints at the biomaterial surface are of major importance since these features will direct the cell responses. Studies on osteoblastlike cell reactivity towards materials will have to focus on the different steps of protein and cell reactions towards defined surface properties. The introduction of new techniques allows nowadays the fabrication of materials with ordered surface structures. This paper gives a review of present knowledge on the various stages of osteoblast reactions on material surfaces, focused on basic cell events under in vitro conditions. Special emphasis is given to cellular reactions towards ordered nano-sized topographies.

    2015-01-01

    This novel approach to the foundation of the physical theory begins with thought experiments on measurement practice like Einstein for relativistic Kinematics. For a similar foundation of Dynamics one can start from Hermann von Helmholtz analysis of basic measurements. We define energy, momentum and mass from elemental ordering relations for "capability to execute work" and "impact" in a collision and apply Helmholtz program for quantification. From simple pre-theoretic (principle of inertia, impossibility of Perpetuum Mobile, relativity principle) and measurement methodical principles we derive all fundamental equations of Mechanics. We explain the mathematical formalism from the operationalization of basic observables.

    2001-03-01

    Technological advances in basic biological research have been instrumental in recent biomedical discoveries, such as in the understanding and treatment of cancer, HIV/AIDS, and heart disease. However, many of these advances also raise several new ethical challenges. For example, genetic research may pose no physical risk beyond that of obtaining the initial blood sample, yet it can pose significant psychological and economic risks to research participants, such as stigmatization, discrimination in insurance and employment, invasion of privacy, or breach of confidentiality. These harms may occur even when investigators do not directly interact with the person whose DNA they are studying. Moreover, this type of basic research also raises broader questions, such as what is the definition of a human subject, and what kinds of expertise do Institutional Review Boards (IRBs) need to review the increasingly diverse types of research made possible by these advances in technology. The National Bioethics Advisory Commission (NBAC), a presidentially appointed federal advisory committee, has addressed these and other ethical, scientific and policy issues that arise in basic science research involving human participants. Two of its six reports, in particular, have proposed recommendations in this regard. "Research Involving Human Biological Materials: Ethical and Policy Guidance" addresses the basic research use of human tissues, cells and DNA and the protection of human participants in this type of research. In "Ethical and Policy Issues in the Oversight of Human Research" NBAC proposes a definition of research involving human participants that would apply to all scientific disciplines, including physical, biological, and social sciences, as well as the humanities and related professions, such as business and law. Both of these reports make it clear that the protection of research participants is key to conducting ethically sound research. By ensuring that all participants in

    2004-01-01

    The UN/ESA Workshops on Basic Space Science is a long-term effort for the development of astronomy and regional and international co-operation in this field on a world wide basis, particularly in developing nations. The first four workshops in this series (India 1991, Costa Rica and Colombia 1992, Nigeria 1993, and Egypt 1994) addressed the status of astronomy in Asia and the Pacific, Latin America and the Caribbean, Africa, and Western Asia, respectively. One major recommendation that emanated from the first four workshops was that small astronomical facilities should be established in developing nations for research and education programmes at the university level and that such facilities should be networked. Subsequently, material for teaching and observing programmes for small optical telescopes were developed or recommended and astronomical telescope facilities have been inaugurated at UN/ESA Workshops on Basic Space Science in Sri Lanka (1995), Honduras (1997), and Jordan (1999).

  9. Basic analysis of regularized series and products

    CERN Document Server

    Jorgenson, Jay A

    1993-01-01

    Analytic number theory and part of the spectral theory of operators (differential, pseudo-differential, elliptic, etc.) are being merged under amore general analytic theory of regularized products of certain sequences satisfying a few basic axioms. The most basic examples consist of the sequence of natural numbers, the sequence of zeros with positive imaginary part of the Riemann zeta function, and the sequence of eigenvalues, say of a positive Laplacian on a compact or certain cases of non-compact manifolds. The resulting theory is applicable to ergodic theory and dynamical systems; to the zeta and L-functions of number theory or representation theory and modular forms; to Selberg-like zeta functions; andto the theory of regularized determinants familiar in physics and other parts of mathematics. Aside from presenting a systematic account of widely scattered results, the theory also provides new results. One part of the theory deals with complex analytic properties, and another part deals with Fourier analys...

  10. Basic Testing of the Duchamp Source Finder

    CERN Document Server

    Westmeier, Tobias; Serra, Paolo

    2011-01-01

    This paper presents and discusses the results of basic source finding tests in three dimensions (using spectroscopic data cubes) with Duchamp, the standard source finder for the Australian SKA Pathfinder. For this purpose, we generated different sets of unresolved and extended HI model sources. These models were then fed into Duchamp, using a range of different parameters and methods provided by the software. The main aim of the tests was to study the performance of Duchamp on sources with different parameters and morphologies and assess the accuracy of Duchamp's source parametrisation. Overall, we find Duchamp to be a powerful source finder capable of reliably detecting sources down to low signal-to-noise ratios and accurately measuring their position and velocity. In the presence of noise in the data, Duchamp's measurements of basic source parameters, such as spectral line width and integrated flux, are affected by systematic errors. These errors are a consequence of the effect of noise on the specific algo...

    2016-03-01

    Biliary self-expandable metal stents (SEMS), a group of non-vascular stents, have been used in the palliative management of biliary obstruction around the world. However, there are still unmet needs in the clinical application of biliary SEMS. Comprehensive understanding of the SEMS is required to resolve the drawbacks and difficulties of metal stent development. The basic structure of SEMS, including the materials and knitting methods of metal wires, covering materials, and radiopaque markers, are discussed in this review. What we know about the physical and mechanical properties of the SEMS is very important. With an understanding of the basic knowledge of metal stents, hurdles such as stent occlusion, migration, and kinking can be overcome to develop more ideal SEMS. PMID:27000423

    2011-01-01

    Dengue is one of the major international public health concerns. Although progress is underway, developing a vaccine against the disease is challenging. Thus, the main approach to fight the disease is vector control. A model for the transmission of Dengue disease is presented. It consists of eight mutually exclusive compartments representing the human and vector dynamics. It also includes a control parameter (insecticide) in order to fight the mosquito. The model presents three possible equilibria: two disease-free equilibria (DFE) and another endemic equilibrium. It has been proved that a DFE is locally asymptotically stable, whenever a certain epidemiological threshold, known as the basic reproduction number, is less than one. We show that if we apply a minimum level of insecticide, it is possible to maintain the basic reproduction number below unity. A case study, using data of the outbreak that occurred in 2009 in Cape Verde, is presented.

    The theory of electromagnetism is taught as a part of most contemporary electrical engineering curricula. Usually a basic course is intended to cover all the fundamental electromagnetic theory which is needed in later engineering courses. However it is often found that students fail to understand...... theoretical course contents have been reduced to a core of fundamental principles. These are combined with the study of magnetic properties of materials closely related to manufacturer's data sheets. To enhance the understanding of these fundamentals, practical topics from engineering technology are included....... Components or systems that combine magnetic, electrical and mechanical aspects are preferred. Also, a series of hands-on lab projects give the students an opportunity to learn by doing. The topics that are covered by the course are outlined. By integrating the teaching of basic physical laws...

    The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variations Contrary to pre-launch expectations, the image quality is continuously evolving, during commissioning and the nominal mission. Payload decontaminations and wavefront sensor assisted refocuses have been carried out to recover optimum performance. An ESA-Airbus DS working group analysed the straylight and basic angle issues and worked on a detailed root cause analysis. In parallel, the Gaia scientists have also analysed the data, most notably comparing the BAM signal to global astrometric solutions, with remarkable agreement. In this contribution, a status review of these issues will be provided, with emphasis on the mitigation schemes and the lessons learned for future space missions where extreme stability is a key requirement.

    Krantz, D. H.

    2006-12-01

    Societal use of well-understood physical or biological science generally involves social processes, including dissemination of the knowledge across society and modification of public policy and of group and individual behavior. The social processes are often poorly understood, from the standpoint of social science; thus, questions in applied natural science often give rise to fundamental questions within social science. For example, problems concerning communication of uncertain scientific information give rise to basic research about how conceptual frameworks (of both the recipients and the providers of such information) change, over the course of repeated attempts at communication. Our Center has been exposed to such communication problems, in several field projects, and this exposure has suggested fruitful new directions for our laboratory research on decision making. For example, we noted (as others have) that communication is often more effective when presented to a group of peers gathered in a familiar setting than to individuals. Among other observations, Orlove and his collaborators noted that Ugandan villagers gather in groups to hear radio broadcasts of climate forecasts together. What behavioral processes lead to more effective communication to groups? Does the social setting enhance individual learning? Does the group frame decision problems differently from the average individual member? Are individual goals modified by the group setting? All three of these processes may be important; we have results concerning each from our current laboratory experiments. I argue that these ideas also require major modification of current theories of decision making, and so are particularly fruitful for basic research in the Decision Sciences. Our experience has led us to emphasize the very close relation between basic and applied social research. We also believe that social-science students need much stronger education in natural sciences and/or engineering, in order

The goal of this investigation was to find out whether there is a set of concepts that may be considered to be basic to all these five social sciences. The set of concepts found will be modeled in terms of automata, thus providing a way of unifying the five fields in a general mathematical setting.

    The book introduces ‘the state of the art' of pulsed laser ablation and its applications. It is based on recent theoretical and experimental studies. The book reaches from the basics to advanced topics of pulsed laser ablation. Theoretical and experimental fundamental phenomena involved in pulsed laser ablation are discussed with respect to material properties, laser wavelength, fluence and intensity regime of the light absorbed linearly or non-linearly in the target material. The energy absorbed by the electrons leads to atom/molecule excitation, ionization and/or direct chemical bond breaking and is also transferred to the lattice leading to material heating and phase transitions. Experimental  non-invasive optical methods for analyzing these phenomena in real time are described. Theoretical models for pulsed laser ablation and phase transitions induced by laser beams and laser-vapour/plasma interaction during the plume expansion above the target are also presented. Calculations of the ablation speed and...

  5. Basic Safety Standards for Radiation Protection

    International Nuclear Information System (INIS)

    Pursuant to the provisions of its Statute relevant to the adoption and application of safety standards for protection against radiation, the Agency convened a panel of experts which formulated the Basic Safety Standards set forth in this publication. The panel met under the chairmanship of Professor L. Bugnard, Director of the French Institut National d'Hygiene, and representatives of the United Nations and of several of its specialized agencies participated in its work. The Basic Safety Standards thus represent the result of a most careful assessment of the variety of complex scientific and administrative problems involved. Nevertheless, of course, they will need to be revised from time to time in the light of advances in scientific knowledge, of comments received from Member States and of the work of other competent international organizations. The Agency's Board of Governors in June 1962 approved the Standards as a first edition, subject to later revision as mentioned above, and authorized Director General Sigvard Eklund to apply the Standards in Agency and Agency-assisted operations and to invite Governments of Member States to take them as a basis in formulating national regulations or recommendations on protection against the dangers arising from ionizing radiations. It is mainly for this last purpose that the Basic Safety Standards are now being published in the Safety Series; but it is hoped that this publication will also interest a much wider circle of readers.

    2011-01-01

    Volume or statistical averaging of the microscopic Maxwell equations (MEs), i.e. transition from microscopic MEs to their macroscopic counterparts, is one of the main steps in electrodynamics of materials. In spite of the fundamental importance of the averaging procedure, it is quite rarely properly discussed in university courses and respective books; up to now there is no established consensus about how the averaging procedure has to be performed. In this paper we show that there are some basic principles for the averaging procedure (irrespective to what type of material is studied) which have to be satisfied. Any homogenization model has to be consistent with the basic principles. In case of absence of this correlation of a particular model with the basic principles the model could not be accepted as a credible one. Another goal of this paper is to establish the averaging procedure for metamaterials, which is rather close to the case of compound materials but should include magnetic response of the inclusi...

    2005-01-01

    Objective The purpose of the basic safety courses is to increase awareness for everyone working on the CERN site (CERN staff, associates, outside companies, students and apprentices) of the various hazards existing on site, and how to recognise and avoid them. Safety course changes The current organisation of basic safety courses is changing. There will be two main modifications: the organisation of the courses and the implementation of a specific new training course for the LHC machine during the LHC tests and hardware commissioning phase. Organisational changes This concerns the existing basic safety training, currently called level 1, level 2 and level 3. Under the new procedure, a video will be projected in registration building 55 and will run every day at 14.00 and 15.00 in English. The duration of the video will be 50 minutes. The course contents will be the same as the slides currently used, plus a video showing real situations. With this new organization, participants will systematically follow...

    A point on the distinction between design and science is given and the connotations of design science are discussed in the paper. Design should be understood as the first step of all human’s purposeful activity, which is a daily behavior for everyone. Four laws are summarized,which describe the basic patterns of design and are the constituents of design science. They are the law of design based on existed knowledge,law of in-completeness of design knowledge,law of design centered on new knowledge acquirement and law of competi-tiveness of design knowledge. The four basic laws show the knowledge essence of design. To enrich the existed knowledge,to make it convenient to be used,to teach designers with high intuition and inspiration in picking useful elements of existed knowledge and shaping competitive ideas and to have strong new knowledge acquire-ment facility are the basic conditions of good designs. Study of design science will promote the structure of tra-ditional engineering education. An important conclusion is derived that there will be no successful innovation without good design.

    A major branch of glycobiology and glycan-focused biomedicine studies the interaction between carbohydrates and other biopolymers, most importantly, glycan-binding proteins. Today, this research into glycan-biopolymer interaction is unthinkable without glycan arrays, tools that enable high-throughput analysis of carbohydrate interaction partners. Glycan arrays offer many applications in basic biochemical research, for example, defining the specificity of glycosyltransferases and lectins such as immune receptors. Biomedical applications include the characterization and surveillance of influenza strains, identification of biomarkers for cancer and infection, and profiling of immune responses to vaccines. Here, we review major applications of glycan arrays both in basic and applied research. Given the dynamic nature of this rapidly developing field, we focus on recent findings.

    Full Text Available For grant proposals the investigator has to include an estimation of sample size .The size of the sample should be adequate enough so that there is sufficient data to reliably answer the research question being addressed by the study. At the very planning stage of the study the investigator has to involve the statistician. To have meaningful dialogue with the statistician every research worker should be familiar with the basic concepts of statistics. This paper is concerned with simple principles of sample size calculation. Concepts are explained based on logic rather than rigorous mathematical calculations to help him assimilate the fundamentals.
