New evidence of ammonites and its sedimentary context within Upper part of Chokolate Formation (Yura, Arequipa) De la Cruz AA, Acosta-Pereira H, Aldana M Instituto Geológico Minero y Metalúrgico INGEMMET, Dirección de Geología Regional. Av. Canadá N° 1470, San Borja, Lima, Perú, email@example.com In District of Yura, Province and Department of Arequipa (southern Peru), there are several studies in petrology and stratigraphy (Jenks, 1958; Benavides, 1962; Vargas, 1970; Vicente, 1981; León, 1981; Vicente qt al., 1982). In this study, we show an update on knowledge of sedimentological and paleontological elements in Chocolate Formation, in cerro Yanacoto; reporting for this area fluvial and marine sedimentary sequences, both containing fauna of ammonites in marine facies. This study relates paleontological features on the sedimentological context in which the ammonites were found. At cerro Yanacoto, up to 170 m. in the stratigraphic column (at the top of the Sequence 1) at Chocolate Formation, there are layers containing carbonated silty sediments, that contain two fossiliferous levels, separated each other by 50 cm. in thickness by fine grained sandstone, collected at total about ten internal molds of ammonites found in normal position and regular state conserved. These are ammonites, which paleontological features consists of small size, umbilical diameter about 2 to 5 cm., first whorl height range between 1.5 to 2 cm., evolute to slightly involute, some samples, can be observed at least 4 whorls, venter is slightly rounded and very narrow, and the ornamentation consists of simple and straight ribs on the flanks; and on its ventro-lateral shoulders, bending are observed toward growth direction of the shell. These characteristics correspond to Arietitidos. Regarding Uptonia sp., they are compressed, with coarse ribs and coarse to slightly regular folds relatively next to ventral zone, they are not tuberculated. These ammonites were found in a siltstone-shales intercalation, some of them with thin sandstone layers and calcareous components within a ~2 meter strata, which there are two fine grained levels. In the first level, there are the ammonites Megarietites sp., Eparietites sp. and Uptonia sp., followed by a chaotic sedimentation Abstracts and Program, LAK 2009, Göttingen, 7.4. to 9.4. 2009 71s and Program, LAK 2009, Göttingen, 7.4. to 9.4. 2009 71 represented by convoluted laminations, accompanied by synsedimentary normal microfaults cutting unconsolidated layers; above these levels, the second level is located, containing Megarietites meridionalis (REYNES), Eparietites cf. undaries (QUENSTEDT) and Arnioceras sp. The presence of ammonites Arietítidos, is characteristic of Sinemurian times, Arietitidos ammonites reported in this study are present in Lower Sinemurian beds in northern Siberia and in the Mediterranean Sinclinal Belt in Russia (Krymholts et al., 1988), these environments are relatively deep, and also, there are reported I relatively shallow marine water. Moreover, sedimentary evidences suggest a deltaic sedimentary environment, in a slope with strong deformed strata. According to those evidences, is very possible that these ammonites have undergone short post-mortem transport. In conclusion, ammonites reported at the top part of the Sequence 1 of Chocolate Formation, correspond to Megarietites meridionalis REYNES, Eparietites cf. undaries (QUENSTEDT), Megarietites sp., Eparietites sp. and Uptonia sp.; these are Sinemurian and Lower Pliensbachian ammonites, and lived in relatively deep marine water. These ammonites were found next to post-mortem transport evidences that correspond to a slope facies. Stratigraphic column in cerro Yanacoto shows a sequence of sedimentary rocks, involving conglomerates, sandstone and siltstone from continental environments, with occasional deposits of siltstone-shales, which correspond to marine sea level rise in thin thicknesses.


This paper considers the Lie bialgebra structures on a type of twisted Schrdinger-Virasoro Lie algebra. It is proved that all bialgebra structures on this type Lie algebra are triangular coboundary.


The application of soft-switching techniques is increasing in the DC/DC converter area. It is important to design soft-switching parameters to ensure the converter operates properly and efficiently. An optimized design method is presented in this paper. The objective function is the total power loss of a converter, while the variables are soft-switching parameters and the constraints are the electrical requirements for soft-switching. Firstly, a response surface methodology (RSM) model with a high precision is built, and the rough optimized parameters can be obtained with the help of a genetic algorithm (GA) in the solution space determined by the constraints. Secondly, a re-optimization is conducted with a SPICE model and a GA, and accurate optimized parameters can be obtained. Simulation and experiment results show that the proposed method performs well in terms of a wide adaptability, efficiency, and global optimization.


Kidney transplant (KT) candidates have historically low immunization rates against recommended vaccines. A retrospective study of KT candidates was conducted to assess contemporary vaccination rates and vaccine uptake during pre-transplant evaluation.

 All KT candidates ≥ 18 years referred to Transplant Infectious Disease Clinic for pre-transplant evaluation between January 1, 2020 and August 31, 2020 were retrospectively studied for history of prior vaccination against Tdap, 13 valent pneumococcal conjugate vaccine (PCV13), 23 valent pneumococcal polysaccharide vaccine (PPSV23), Hepatitis A and B (using Hepatitis A total IgG and Hepatitis B surface antibodies as surrogate markers) and recombinant zoster vaccine (RZV). Seropositivity (as a marker of immunity) against measles, mumps, rubella and varicella was also assessed.

 109 KT candidates were evaluated (tables 1 & 2). Rates of prior vaccination against Tdap, PCV13 and PPSV23 were 33%, 58%, and 67%. Only 5 (8%) of 61 patients ≥ 50 years of age had received 2 doses of RZV. Thirty (28%) had positive Hepatitis A total IgG and 72 (66%) patients had a positive Hepatitis B surface antibody. Among 37 patients with negative Hepatitis B surface antibody, most had received at least one dose of Hepatitis B vaccine (five were non responders, 19 had had initiated the vaccine series and one had waning antibody response). 79-96% patients had immunity against measles, mumps, rubella and varicella. Patients ≥ 50 years (vs under 50 years) had numerically higher immunization rates against PCV13 and PPSV23 (67% vs 46% and 74% vs 58%) and higher rates of immunity against measles, mumps, rubella and varicella (95% vs 73%; 85% vs 69%, 95% vs 81% and 100% vs 92% respectively). Dialysis patients had a higher Hepatitis B surface antibody compared to non-dialysis patients (78% vs 39%).
 Only 6 of 109 patients were fully immunized. Among 103 vaccine eligible patients, 99 (96%) agreed to get vaccinated. Table 1Baseline characteristics of kidney transplant candidates
 Table 2 Vaccination in kidney transplant candidates

 KT candidates have low rates of prior immunization against Tdap, PCV13, PPSV23, Hepatitis A and B and RZV but high rates of serological immunity against measles, mumps, rubella and varicella. The vaccine uptake during pre-transplant evaluation was high and it provides an unique opportunity to improve immunization in this population.

Abstract Chiral primary amines containing the (R,R)- and (S,S)-trans-cyclohexane-1,2-diamine scaffold and a pyrimidin-2-yl unit are synthesized and used as general organocatalysts for the Michael reaction of α-branched aldehydes to maleimides. The reaction takes place with 10 mol% organocatalyst loading and hexanedioic acid as cocatalyst in aqueous N,N-dimethylformamide at 10 °C affording the corresponding succinimides in good yields and enantioselectivities. DFT calculations support the stereochemical results and the role played by the solvents.

Introduction: Presently, one observes a growing number of enthusiasts of calculated-risk sports, in which the uncommon is revealed according to the disposition of information manifested by the environment, whether in nature or in the urban environment. The practice of adventure and risk sports, such as surfing, biking, skating, skateboarding and others, and recently in Brazil, parkour, originates from a spectacular revolution and from logical adaptation to an age of dizzying exchanges, which we watch today. There is social construction of extreme risk among youths, materialized in games and sports that emphasize excellence of performance in urban sports, called "radical" sports, such as biking, inline skating and skateboarding, and, more recently in Brazil, in the leisurely practice of Parkour, a sport that grows by the day among young people. Denominated by many authors as a social category, youth is considered to be a transitional phase, in which passing from a more withdrawn, dependent social condition to a broader condition occurs. It can be considered a period of preparation for entering adult social life (Abramo, 1994, in Sallas, 1999). In this way, these youths embrace the practice of adventure sports with the boldness necessary to an age of transition. With great courage, they appropriate city spaces (enchanted by them) that often seem to be forgotten on weekends and are rarely frequented by the working populous. With their maneuvers, pirouettes and acrobatics, the young adventurers give a personal touch to the public area in a demonstration of pleasure and vitality of the embraced sport. Skating and Parkour are treated here as urban-adventure practices, in which these young enthusiasts, during their leisure hours, imprint their actions with truly challenging meanings, overcoming barriers and possible prejudices of the society imposed upon them. In a study about street skateboarding entitled Adventure and Risk in Street Skateboarding: a study of the social nature of the imaginary world of young skaters, Costa (2004) introduces us to the people of the skater tribe, who present themselves as "new" urban architects, which, with their careless, fearless ways, emerge as architects of ideas. With their adventures, they engender paths, constructing obstacles and seeing the city as a lover ready to embrace them, showing them the curves and lines of this space full of uncertainties and mysteries. Seduced by new challenges, they encounter this lifestyle. These youths redefine public space, creating places, revitalizing modernity, developing other ways of seeing things and re-creating the city through experiencing the slips and slides of their adventures. Le parkour, a present-day urban sport, newly introduced in Brazil (2004), has already seduced various adepts. Various groups are still being created in some states like São Paulo, Brasília and Rio de Janeiro, with the intention of showing the growth of the sport and of erecting the foundation of the new tribe. It is a so-called radical practice, in which youths jump over obstacles like walls and stairways, going up or down buildings, and showing acrobatic efficiency, strength and agility. According to the site , there are divergences over the creation of parkour. Since primordial times, we have lived with freedom of movement. This rediscovery was experienced and the present characteristics were acquired in the 80's on the streets of Lisse, a suburb of Paris. Two young friends, who used to train this sport together, today dispute the authorship of parkour. They are David Belle (considered by the great majority to be the true creator) and Sébastian Foucan. At fifteen, Belle decided to take his gymnasium experience in gymnastics and martial arts to the streets, sharing it with his childhood friends, and also with Foucan, the main person responsible for the creation of various techniques and the systemization of the sport which would become known as parkour years later. They experienced the influences of lifesaving operations performed by elite firemen, through the natural method of training the body developed by George Herbert, and through escape techniques used in the Vietnam War. Fantasizing emergency situations, where they would need to perform lifesaving operations in hard-to-get-to places, they would train their minds and bodies to overcome any obstacle that they encountered on the way. That way, David acquired the movements and the training of the firemen, training his mind during his moments of fantasy in the Parisian suburb where he lived. Because it was extremely malleable, daring and challenging, the Yamakasi group, formed by Belle and his friends in the early days, captivated new enthusiasts on its trips through Europe. Street Skateboarding and Le Parkour are two, juvenile-style sports that redirect one's views of cities. The study has two objectives: (a) to investigate the meaning of adventure, risk and vertigo in the urban environment factors which appear in the conversations of street skaters and parkour enthusiasts and (b) to place in evidence the symbolic elements that emerge in these conversations.

Purpose The Pascal® dynamic tonometer is a new non-applanation contact tonometer designed to be largely independent of the structural properties of the cornea. It measures the systolic and diastolic IOP and their difference to determine OPA. By recording the pulsatile component of ocular blood flow (heart pulse as a function of time) the OPA could provide an indirect measurement of the choroidal perfusion. It has been suggested that OPA could be an indirect risk factor for glaucoma progression. We aimed to assess the short-time variability of OPA in healthy persons

Methods The left eyes of 30 healthy subjects were included in this prospective study. The IOP was measured twice by Goldmann applanation tonometers (GAT) followed by 3 consecutive measurements by DCT 10 min later. Pachymetry, arterial blood pressure and pulse rate were measured after IOP measurements. These measurements were repeated with an interval of fifteen days at the same hour of the first measurements. The mean value of each parameter was taken into account for the statistical analysis. Student Test was used to assess the difference and the Pearson correlation was used to assess the correlation between the various parameters

Results The mean age was 41 ± 12 years. The mean IOP at the first visit was 13.6 ± 2.9 mmHg by GAT and 14.3 ± 2.2 mmHg by DCT. The mean OPA was 2.4 ± 0.9 mmHg (0.8 to 4.3 mmHg) at the first visit. The mean IOP at the second visit was 13.4 ± 3.2 by GAT and 15.0 ± 2.5 mmHg by DCT. The mean OPA was 2.6 ± 1.0 (0.9 to 5.8) mmHg at the second visit.

Conclusion There was no significant difference in both OPA measurements. This parameter remains stable in a short-time interval in healthy subjects.


PURPOSE In 2005, the American College of Rheumatology/Association of Rheumatology Health Professionals (ACR/ARHP) workforce study documented a shortfall of rheumatologists expected in the United States over the next 20 years. In response to these fi ndings, potential solutions were suggested: improve practice effi ciency, increase rheumatology physician fellowships, and increase the use of physician assistants (PAs) and NPs in rheumatology practice. Efforts were made to implement these recommendations. In 2015, additional key variables affecting the rheumatology workforce included a growing predominance of millennials and an increasing shift to a predominantly female workforce. The 2015 ACR/ARHP study described the rheumatology workforce, including the role of PAs and NPs.

Abstract In the Dzhungarian Alatau, a large Asian mountain range, 33 species from the polymorphic genus Allium L. have been found. They belong to the subgenera Rhizirideum , Allium and Melanocrommyum and are distributed from the foothills to alpine belts. The geographical and genesis analysis of these species is given. Five species can be ascribed to the category of autochtonous of the region, among them one being endemic to the Dzhungarian Alatau.


Provided is an attachment structure capable of ensuring the support rigidity of an assist grip against tensile force, and the impact-absorbing function of the assist grip against pressing force. A weak part (34) and a high-rigidity part (36) are provided to a grip attachment bracket (14) to which an assist grip (10) is attached. When pressing force (Fpr) is applied, a flange part (50) on a clip (40) fixedly provided to the assist grip (10) presses on and deforms the weak part (34) so that the impact of the pressing force (Fpr) is absorbed by deformation of the weak part (34). When tensile force (Fex) is applied, a locking claw (48) provided to the clip (40) engages the high-rigidity part (36) so that the assist grip (10) is supported with high rigidity by the high-rigidity part (36).


Concentrations of citronellol and geraniol in essential oil from rose geranium (Pelargonium hybrid) were monitored monthly over four years using gas chromatography-mass spectrometry. Geraniol concentrations fell in winter and citronellol concentrations increased in spring. The citronellol/geraniol (C:G) ratio was a more sensitive indicator of change in oil composition than the concentration of either alcohol in isolation. C:G ratios rose sharply if the minimum air temperature (T-min) fell below 5.5 degrees C for any time during the 5 d prior to monthly harvesting, A nonlinear model is proposed to predict the C:G ratio at any T-min. High C:G ratios indicated cold stress in geranium plants.


The surface water quality monitoring is an important concern of pub6 lic organizations due to its relevance to the public health. Statistical methods are 7 taken as consistent and essential tools in the monitoring procedures in order to 8 prevent and identify environmental problems. This work presents the study case of 9 the hydrological basin of the river Vouga, in Portugal. The main goal is discrimi10 nate the water monitoring sites using the monthly dissolved oxygen concentration 11 dataset between January 2002 and May 2013. This is achieved through the extrac12 tion of trend and seasonal components in a linear mixed-effect state space model. 13 The parameters estimation is performed with both maximum likelihood method 14 and distribution-free estimators in a two-step procedure. The application of the 15 Kalman smoother algorithm allows to obtain predictions of the structural com16 ponents as trend and seasonality. The water monitoring sites are discriminated 17 through the structural components by a hierarchical agglomerative clustering pro18 cedure. This procedure identified different homogenous groups relatively to the 19 trend and seasonality components and some characteristics of the hydrological 20 basin are presented in order to support the results. 21

The BRICS Grouping (Brazil, Russia, India, China and South Africa) and the IBSA Dialogue Forum (India, Brazil and South Africa)represent interregional cooperative mechanisms of increasing importance in international relations. This can be attributed to the recent rise of the global South, placing unprecedented emphasis on South?South cooperation. With three members in common, the necessity for and contribution of both IBSA and BRICS are often called into question. IBSA?s two-year successive postponement of its annual summit, five of which have taken place thus far, has prompted questions regarding the continued relevance of an organisation which in many ways is viewed as duplicating the functions of BRICS. Combined with the fact that BRICS contains the political-economic weight of Russia and China (permanent members of the United Nations Security Council and Nuclear Superpowers), the future of IBSA is doubted by some. To determine the future of IBSA, it is important to examine how it differs from BRICS in terms of capacity, priorities and political character.

THE COSTLINESS of international commercial arbitration is a frequent subject of complaint. In many cases, the costs of the proceedings are high, compared both with the amount in dispute and with the costs of similar proceedings before the courts.1

When a party brings a case to arbitration and chooses an arbitration centre, an arbitrator and counsel, it wants to win the case, to gain advantages in the procedure and, in defence against advantages sought by the opponent party, to assure fairness and justice to the process and its outcome. Cost considerations probably are of secondary importance in these decisions, at least in the more important cases.2

Nevertheless, the cost of proceedings is receiving increasing attention from arbitration specialists3 and in the debate between the users of arbitration services and those who provide them. The issue of costs is also being used in the competition between different suppliers of such services (primarily between arbitration centres),4 and in the competition between suppliers of arbitration, and the suppliers of those services which have come to be described as Alternative Dispute Resolution (ADR). Where different methods of dispute resolution are seen by their users as satisfying equally a party's principal objectives just described,5 the secondary objective of costs may indeed become a major consideration.

This article examines the factors which determine the costs of international commercial arbitration and seeks to identify the scope for cost-control and possible cost reductions. It will demonstrate that, in view of the particularities of the disputes considered, cost-control must be directed primarily to a more efficient management of the arbitration proceedings. This requires not only a limitation of the 'time-consuming formalities of proceedings before a court', but also above all, a high degree of interactivity between the parties and the arbitrators in a process …


Thehigher incidence ofbreast cancer among African-American women younger than 50as compared towhite womenpoints tothe need toexamine exposures that arecommon among younger women, including exposure tooral contraceptives (OC). Weexamined patterns ofOC useandtheir associations with breast cancer inapopulation-based, case-control study conducted inNorth Carolina between 1993 and1996. Thestudy population wascomprised of858 cases and789controls, ofwhom40%were African-American women. There waslittle evidence that breast cancer wasassociated with OCuseamong older women(age >50) ofeither race, most ofwhomdiscontinued use inthe distant past. Among younger women, there wasamodest, but nonsignificant, increase inrisk associated with ever useofOCsfor both African-American andwhite women. There wasatrend ofincreasing risks with more recent useamong AfricanAmerican women, whereas nosuch trend wasapparent for white women. Overall, wefound moresubstantial agedifferences than race differences inpatterns ofOCuseandtherisk of breast cancer associated with their use. Thesimilarity oftheassociations between AfricanAmerican andwhite women suggest that racial differences inbreast cancer incidence arenot likely tobeattributable toOCuse.

This thesis intends to examine whether the state or the public judging an individual`s desire or satisfaction have the moral right and objectivity to make that judgment through analyzing "In Broad Daylight", an episode from Under the Red Flag, written by the Chinese-American author Ha Jin. "In Broad Daylight", which is set in China after The Cultural Revolution, shows the unreasonableness of mass psychology and the injustice of a national power through describing the public humiliation of the prostitute Mu Ying. The controversial point at issue is that the government dignitaries and the Red Guards are they themselves involved with prostitution. Through developing this process, Ha Jin shows the ignorance and amorality of the state and the public in general. Jacques Lacan asserts that desire has its roots in something that is lacking and queries his readers as to whether they are acting according to their desires or not, and further advises them to never give up on their desires. However, consideration for the social punishment that may follow an individual`s desire often makes people thwart the realization of that desire. This research, therefore, intends to contemplate the way in which the state and the masses exercise their power over individuals and how the state and the masses fall into the predicament of abusing power while not achieving justice or morality in the procedure of an individual`s trial.


The low frequency Raman spectra for 2,3‐dihydrofuran and 2,3‐dihydrothiophene have been recorded in the region of the ring puckering vibrations. Only Δν = 2 transitions were observed beyond the region of the rotational envelope for both molecules. The observed transitions in the Raman effect for 2,3‐dihydrofuran are in good agreement with the frequencies inferred from the previously reported infrared data. The data indicate that the 0 → 1 transition lies at 19.5 ± 0.5 cm−1 and the molecule is puckered with a barrier of 83 cm−1 to planarity. The previously unreported ring puckering transitions of 2,3‐dihydrothiophene have been reasonably well reproduced by the potential V(X) = 6.40 × 105X4 − 2.89 × 104X2 giving a barrier to planarity of 325 cm−1. These direct observations are in disagreement with the midinfrared difference band series previously reported.


Corticobasal syndrome (CBS) is a clinical entity characterized by higher cortical dysfunctions associated with asymmetric onset of levodopa‐resistant parkinsonism, dystonia and myoclonus. One of the most typical and distressful features of CBS is limb apraxia, which affects patients in their everyday life. Transcranial direct current stimulation (tDCS) is a non‐invasive procedure of cortical stimulation, which represents a promising tool for cognitive enhancement and neurorehabilitation. The present study investigated whether anodal tDCS over the parietal cortex (PARC), would improve ideomotor upper limb apraxia in CBS patients.


The electronic correlation energy of diatomic molecules and heavy atoms is estimated using a back propagation neural network approach. The supervised learning is accomplished using known exact results of the electronic correlation energy. The recall rate, that is, the performance of the net in recognizing the training set, is about 96%. The correctness of values given to the test set and prediction rate is at the 90% level. We generate tables for the electronic correlation energy of several diatomic molecules and all the neutral atoms up to radon (Rn). © 1997 by John Wiley & Sons, Inc. J Comput Chem 18: 1407–1414, 1997


ABSTRACT Cu-rich precipitates are the important influence factors for the irradiation embrittlement of the reactor pressure vessel model steels. The microstructure of the Cu-rich precipitates could be revealed by mechanical and magnetic properties. In this article, the effect of the Cu-rich precipitates on thermal conductivity was studied. The reactor pressure vessel (RPV) model steels were aged for different time at 500°C. The results show that the thermal conductivity of RPV model steel is first decreased and then increased during the experiment, with a minimum value at 48.33 ± 0.21 W·m−1·K−1 after being aged for 200 h. The changing thermal conductivity is decided by the synergistic effect of the following three factors: (1) the crystal structure transformation of Cu-rich precipitates, (2) the orientation relationship between the matrix and Cu-rich precipitates, (3) the content of Cu atoms in the matrix.


Micro-scale in situ REE analyses of zircon cores and rims have been carried out for eclogites from Xindian, Shuanghe, Huangzhen and jadeite quartzite from Shuanghe, Dabie Mountains. Combining with the CL internal structure and U-Pb dating, we studied the zircon REE composition change from the protolith inherited zircon to the metamorphic zircon during the ultra-high pressure metamorphism. The results show that the inherited core and metamorphic rim have quite different REE contents. It depends on how metamorphic zircon forms, overgrowth or recrystallization of protolith zircon. In general, the metamorphic zircon rims have lower REE contents compared with the protolith cores, especially in HREE. The metamorphic rims also have lower Th/U ratio than that of the cores. Detailed comparative study on REE and Th/U ratio of inherited zircon cores and metamorphic zircon rims may provide important information on forming process of metamorphic zircons and physico-chemical environment when it forms.

Department E was established in 1957. From the very beginning it was laid down that the chief object of the department was to develop the medicamental treatment of psychoses, and to this end psychopharmacological research was to be carried out in the laboratory already in existence in the Male Hospital. Department E comprises 255 beds and supervises four family care homes with some 70 patients in total. Ou t patient treatment, rehabilitation work, occupational and activation therapy in this department are similar to the work being done by the other departments and will not be separately dealt with. Research work on drug therapy has partly consisted in studies of preparations already in existence, especially their clinical results, side effects and possible toxic properties, and partly in testing new drugs in collaboration with Danish and foreign manufacturers. Only such new drugs were tested as were likely to have properties not already covered by the armamentarium of drugs available to the department and likely to be of therapeutical value to the patients. The general principle of medicamental treatment in Department E, to which we have consistently adhered, is the application of a relatively small number of preparations with which we were familiar, and only to introduce new drugs if they had proved valuable by research made by us or other investigators. About 1959 we had reason to believe that research on catecholamines (adrenaline, noradrenaline, and dopamine) and similar compounds (amphetamine and tryptamine) might throw some light on the biology of psychoses and the mode of action of psychopharmaca. Our work in this sphere started by measuring the secretion of catecholamines in the urine of psychotic patients treated with psychopharmaca, partly monamineoxydase inhibitors, which were used in that period to combat depressions, and partly chlorpromazine and reserpine used in treatment of chronic schizophrenic patients. When facilities for experiments on animals were set up in the laboratory, we became interested in examining the behavioural effects of amphetamine in a number of species of animals, as clinical observations seemed to indicate to us that amphetamine psychosis is the model psychosis which resembles certain forms of schizophrenia most of all. The effect of amphetamine on the behaviour of animals soon proved that there was antagonism between the so-called .amphetamine stereotypy* and psychopharmaca with antipsychotic effect.

Upper and lower bounds on the (spatial) maximum electric field outside a radiating system have been obtained and studied. The results should be useful in the design of systems where microwave breakdown is an important consideration.


Doctors may think free pens or lunches from pharmaceutical companies have no effect on their behaviour. But a recent study suggests that even small freebies may contribute to physicians' opioid-prescribing habits.

The study, published in JAMA Network Open , found a strong association between


Oxidative dehydrogenation of ethane to ethylene(ODE) was investigated over Nibased catalyst.The results showed that the catalyst prepared by impregnation has the best catalytic performance.Introduction of CeO2 by impregnation favors the increase of catalytic activity at lower temperature.Characterization of O2-TPD-MS,TPR and XPS revealed that the non-stoichiometric oxygen species(O2-、 O-and O22-) played a critical role in the catalyst activity at relative low temperature,while the surface lattice oxygen species dominated at relative high temperature;The loading of CeO2 reduced the reaction between NiO and γ-Al2O3,promoted the distribution of Ni species on the carrier,thus the amount of highly-distributed NiO microcrystalline which benefited the lower temperature activity was enhanced.Also CeO2 influenced the distribution of surface oxygen species,which mean that the relative content of surface lattice oxygen was increased;however the content of non-stoichiometric oxygen was decreased.


A study of the influence of hydrogen on the mechanical behaviour of five iron alloys with different carbon state, morphology and content (as spheroidal or lamellar graphite or combined as CFe 3 ) is described here. Experimental observations from tensile (carried out at different crosshead speeds), Charpy impact resistance, hardness, fracture toughness tests and fractographic analysis show that internal or dissolved hydrogen, apart from producing a significant loss of ductility, hardens steels and softens cast irons. The results also provide convincing evidence of the important role that the strain rate plays in the mechanism of hydrogen induced cracking. Additionally, glow discharge optical emission spectroscopy (GDOES) technique is used to evaluate the concentration of hydrogen that has been absorbed by the samples as a function of depth and time. It can be deduced from the innovative use of this technique not only that diffusivity of hydrogen in ductile cast irons is greater than in steels or grey cast irons, but also that hydrogen interacts with different trapping sites.


[Purpose] To investigate surgical indication, perioperative complication, risk factors of perioperative mortality and perioperative management for elderly patients over 70 with esophageal cancer, and to explore the methods to decrease perioperative mortality. [Methods] From January 2000 to January 2005, the clinic data of 185 elderly patients over 70 with esophageal cancer un- dergoing radical operation were retrospectively analyzed. Univariate and multivariate Logistic re- gression anlysis were used to examine the risk factors of perioperative mortality. [Results] There was no operative death and the surgical resection rate was 100%. Operation time more than 5h was found in 26 cases. Postoperative complication rate was 28.6%, and perioperative mortality rate was 8.1%. The main reasons of death during perioperative period were pulmonary, cardiovascular complication and anastomotic leakage. Univariate analysis and multivariate analysis by binary Lo- gistic regression indicated that pre-operative with chronic disease, poor preoperative pulmonary function, long operation time, and injury of recurrent laryngeal nerve were significant correlated to perioperative mortality in elderly patients over 70 years with esophageal cancer. [Conclusion] The perioperative complication rate and mortality are relative high in elderly patients with esophageal cancer, strictly surgical indications and effective perioperative management are the most important measures to reduce perioperative mortality.


Although upward comparison may threaten people's self-esteem, it has been argued that this is not the case it the comparison other is an outgroup member. In the latter case, people may protect their self-esteem by dismissing the comparison information involving outgroup members as not self-relevant. We suggest that this self-protective strategy may not work when the outgroup is being perceived as superior to the ingroup on the comparison dimension, so that upward comparison does lower people's self-esteem in an asymmetrical group situation. To test this hypothesis, participants were led to believe that they were inductive rather than deductive thinkers. After doing a test presumably designed to assess either their emotional intelligence or their logical intelligence, they were exposed to bogus information on the performance of another individual who was always described as a deductive thinker and who had performed either better (upward comparison) or worse (downward comparison) than the participants themselves. Supporting the hypothesis, inductive thinkers who had been confronted with the superior performance of a deductive thinker on the logical intelligence test (favorable to the latter) reported lower self-esteem than those confronted with the superior performance of a deductive thinker on the emotional task (unfavorable to the latter). In the former case, the unfavorable position of the ingroup in the asymmetrical comparison context could explain such a result.

Acetylacetone dioxygenase (Dke1) is a bacterial enzyme that catalyzes the dioxygen-dependent degradation of β -dicarbonyl compounds. The Dke1 active site contains a nonheme monoiron(II) center facially ligated by three histidine residues (the 3His triad); coordination of the substrate in a bidentate manner provides a five-coordinate site for O 2 binding. Recently, we published the synthesis and characterization of a series of ferrous β diketonato complexes that faithfully mimic the enzyme – substrate intermediate of Dke1 (Park, H.; Baus, J.S.; Lindeman, S.V.; Fiedler, A.T. Inorg. Chem. 2011 , 50 , 11978 – 11989). The 3His triad was modeled with three different facially coordinating N3 supporting ligands, and substituted β -diketonates (acac X ) with varying steric and electronic properties were employed. Here, we describe the reactivity of our Dke1 models toward O 2 and its surrogate nitric oxide (NO), and report the synthesis of three new Fe(II) complexes featuring the anions of dialkyl malonates. Exposure of [Fe( Me2 Tp)(acac X )] complexes (where R2 Tp = hydrotris(pyrazol-1-yl)borate with R-groups at the 3- and 5-positions of the pyrazole rings) to O 2 at −70 °C in toluene results in irreversible formation of green chromophores (λ max ∼ 750 nm) that decay at temperatures above − 60 °C. Spectroscopic and computational analyses suggest that these intermediates contain a diiron(III) unit bridged by a trans μ -1,2-peroxo ligand. The green chromophore is not observed with analogous complexes featuring Ph2 Tp and Ph TIP ligands (where Ph TIP = tris(2-phenylimidazoly-4-yl)phosphine), since the steric bulk of the phenyl substituents prevents formation of dinuclear species. While these complexes are largely inert toward O 2 , Ph2 Tp-based complexes with dialkyl malonate anions exhibit dioxygenase activity and thus serve as functional Dke1 models. The Fe/acac X complexes all react readily with NO to yield high-spin ( S = 3/2) {FeNO} 7 adducts that were characterized with crystallographic, spectroscopic, and computational methods. Collectively, the results presented here enhance our understanding of the chemical factors involved in the oxidation of aliphatic substrates by nonheme iron dioxygenases. The reactivities of various Fe(II) β -diketonato complexes with O 2 and NO have been examined with spectroscopic, computational, and crystallographic methods. These complexes are models of the mononuclear nonheme Fe enzyme, acetylacetone dioxygenase (Dke1). The synthetic complexes react with O 2 to generate diiron (III) intermediates with trans μ -1,2-peroxo configurations, although dimerization is prevented by incorporation of sterically bulky substituents. Characterization of the Fe-NO adducts also sheds light on the electronic structure of the putative iron-superoxo intermediate in Dke1. 2-acac absorption spectra of 1-acac complexes reaction crystallographic structures of 5-acac Fe( Tp) MCD spectra of 4-acac metric for DFT-optimized models TD-DFT results, absorption EPR spectra of Fe/NO adducts, crystallographic


Zipingpu Concrete Face Rock-fill Dam was considerably damaged by "5.12" Wenchuan Earthquake.The site investigation showed that the maximum permanent settlement was about 100 cm and the horizontal displacement was about 60 cm as a result of the earthquake.The separation between the concrete face and the cushion layer plane was large in area,the dislocation of the construction joints of the concrete face above the reservoir water level was obvious,and the crushed damage of the vertical joints of the concrete face also occurred because of the permanent displacement due to the earthquake.Based on the field investigation,the damage mechanism was analyzed,and proposals were put forward on the future analytical computation of the earthquake effects on concrete face rock-fill dams,anti-earthquake design and the principle for the rehabilitation of the Zipingpu Concrete Face Rock-fill Dam damaged by the earthquake.


The bacterial cell-cell communication process called quorum sensing enables groups of bacteria to synchronously alter behavior in response to changes in cell population density. Quorum sensing relies on the production, release, accumulation, and detection of extracellular signal molecules called autoinducers. Here, we investigate a mechanism employed by a vibriophage to surveil host quorum sensing and tune its lysogeny-lysis decision to host cell density. The phage possesses a gene called vqmAPhage encoding a quorum-sensing receptor homologous to vibrio VqmA. Both VqmA receptors can detect the host bacteria-produced autoinducer called DPO. DPO-bound VqmAPhage launches the phage lysis process. We discover that the bacterial host produces an inducer of the VqmAPhage-directed quorum-sensing lysogeny-lysis transition. Production of the inducer appears to be widespread among bacteria. A screen of the Escherichia coli Keio collection for mutants impaired for inducer production revealed lomR, located in a prophage, and encoding a poorly understood protein. In the E. coli screening strain, lomR is interrupted by DNA encoding an insertion element. The 3' domain of this LomR protein is sufficient to induce VqmAPhage-directed lysis. Alanine-scanning mutagenesis showed that substitution at either of two key residues abrogates inducer activity. Full-length LomR is similar to the outer membrane porin OmpX in E. coli and Vibrio parahaemolyticus O3:K6, and OmpT in Vibrio cholerae C6706, and indeed, OmpX and OmpT can induce VqmAPhage-directed activity. Possibly, development of the LomR, OmpX, or OmpT proteins as tools to direct phage lysis of host cells could be used to control bacteria in medical or industrial settings. ABSTRACT IMPORTANCE Bacteria communicate with chemical signal molecules using a process called quorum sensing. Quorum sensing allows bacteria to track their cell numbers and orchestrate collective behaviors. Recently, we discovered that a virus that infects and kills bacteria "eavesdrops" on its host's quorum-sensing process. Specifically, the virus monitors host cell growth by detecting the accumulation of host quorum-sensing signal molecules. In response to the garnered quorum-sensing information, the virus kills the host bacterial cells when the bacterial population has reached a high cell density. This strategy presumably enhances transmission of viruses to new host cells. Here, we discover and characterize three closely-related bacterial host-produced proteins called LomR, OmpX, and OmpT that are capable of inducing the viral quorum-sensing-mediated killing program. Development of this class of inducer proteins as tools to drive "on demand" virus-mediated lysis of pathogenic host bacterial cells could be used to control bacteria in medical or industrial settings.


This article argues that good program evaluation needs to treat educational innovations and processes as it would any other social program. Drawing on the literature in social program evaluation, we argue for the need to understand the theory behind the project which embodies assumptions about how its effects are produced. Once these are articulated and examined, they can then be incorporated into a program logic which lays out inputs, activities, outputs and outcomes and can be used as a planning document for future curriculum development as well as a template for evaluating the program. Some preliminary data from a current evaluation of the use of sustainable development projects sponsored by Engineers Without Borders Australia exemplify how such an evaluation produces fine grained understandings of the mechanisms at work and their effectiveness. The challenge is thrown out for all engineering academics with an interest in education to incorporate these evaluation approaches into their practice.

Factors affecting the establishment and recruitment of seedlings of the Appalachian endemic Pinuspungens Lamb were studied in pine–oak forests of dry, southwesterly mountain slopes in southwestern Virginia, United States. Recruitment of P. pungens was not limited by seedfall from serotinous cones or by postdispersal seed predation. Total viable seedfall ranged from 35 000 to 69 000 seeds/ha in 1988 and was concentrated in the spring and summer months. Low availability of suitable seedling habitat strongly limited recruitment of P. pungens seedlings. The distributions of habitat variables for P. pungens seedlings and random points in the forest overlapped little, indicating that suitable microsites were relatively rare. Seedlings occurred in microsites characterized by shallow pine litter, low ground and canopy covers, and larger nearest neighbor distances than occurred at random. Summer drought also contributed to low seedling survivorship, particularly in young seedlings. Our results suggest that optimal...


Classical mean-variance portfolio theory tells us how to construct a portfolio of assets which has the greatest expected return for a given level of return volatility. Utility theory then allows an investor to choose the point along this efficient frontier which optimally balances her desire for excess expected return against her reluctance to bear risk. The means and covariances of the distributions of future asset returns are assumed to be known, so the only source of uncertainty is the stochastic piece of the price evolution. In the real world, we have another source of uncertainty - we estimate but don't know with certainty the means and covariances of future asset returns. This note explains how to construct mean-variance optimal portfolios of assets whose future returns have uncertain means and covariances. The result is simple in form, intuitive, and can easily be incorporated in an optimizer.


Background:India being a diverse country has an assortment of various socio-economic and demographic structures. These socio-economic and demographic factors often intervene with the diabetes-free survival in any geographical region. The present study explores diabetes-free survival patterns of adult respondents with respect to various socio-economic and demographic factors in eighteen states of India with better demographic indicators. Material and Methods:The study utilizes data from the fourth round of the District Level Household and Facility Survey (DLHS) undertaken during 2012–2013. The study computes the survival functions by five year age groups followed by Peto and Pike's test for assessing the significant differences in the survival pattern between the various sub-groups in 18 states of India. Results:The study points out that the diabetes-free survival of a respondent is affected by factors such as the place of residence, sex, social group, the standard of living (wealth) index, and region of residence. Conclusions:Timely detection, screening, and treatment of non-communicable diseases, as well as palliative care, are recommended to the community for diabetes prevention. A healthy lifestyle including healthy diet, physical activity on regular basis, and avoiding tobacco needs to be promoted.


Over the last 10 years, the level of inflation has been much lower than in the previous two decades. At the same time, the behaviour of inflation has changed profoundly. By surveying the data and the economic research, the author first examines changes in the variability, growth rates, and behaviour of some of the major macroeconomic variables during the 1980s and 1990s. He then looks at how these changes are linked to a shift in the approach of monetary policy over the period. Lastly, he reviews the economic benefits that these changes have had for Canada.

Although it is implicitly acknowledged that many aspects of contemporary geothermal energy utilization are shrouded in ignorance, this is rarely appreciated or in any way well communicated. Using Jules Verne's science fiction novel A Journey to the Center of the Earth as a means to highlight the inevitable normality of knowledge gaps and uncertainty, certain aspects are discussed that can be applied to communication strategies regarding the unknown in current geothermal energy utilization. This may be important given that risk assessments can often not be communicated meaningfully to citizens and decision makers.


Abstract This study investigated how video caption type affected vocabulary learning and listening comprehension of low-intermediate Chinese-speaking learners of English. Each video was presented twice with one of the five caption types: (1) no caption (NC), (2) full caption with no audio (FCNA), (3) full caption (FC), (4) full caption with highlighted target-word (FCHTW), and (5) full caption with highlighted target-word and L1 gloss (FCL1), where gloss was presented simultaneously with full caption. The results showed that caption type did affect vocabulary learning. FCL1 facilitated the learning of both word form and meaning in a multimedia listening activity. FCHTW increased attention to word form at the expense of word meaning. Videos with either captions (FCNA) or audio (NC) were not helpful for the learning of written words, indicating that presentation of verbal information through two modalities (audio plus text) was superior over single-modality presentation. While caption type had no impact on listening comprehension, concurrent presentations of video, audio, and captions did not overload the learners in the FC condition, suggesting that selective attention might be allocated to different parts of the visual stimuli during the first and second exposure to the videos. Additionally, the presence of highlighted words and glosses in the captioning line might direct learner attention to vocabulary rather than video content.


The subject of the paper is the analysis of the application of house arrest, i.e. the prison sentence that is served in the premises where the convicted person lives, with the aim of pointing out the situation in practice with de lege ferenda proposals. After a brief presentation of the general conceptual framework, purpose and place in the system of criminal sanctions in modern criminal-legal systems and in domestic conditions, the paper presents a normative framework for the application of house arrest in the domain of domestic substantive and executive criminal legislation. Considering the increasingly widespread application of this measure in practice, in a separate part of the paper, disputed issues of both the imposition and execution of house arrest were analyzed, with the argumentation of the need for more precise normative solutions in terms of defining house arrest as a special criminal sanction and not as a modality in the execution of a prison sentence. More precisely regulated issues of competence and organization of the probation service would contribute to overcoming the existing difficulties in the implementation of the house arrest measure.


At the digital era, mass media have sensibly altered the social spheres through broadcasting and promoting various thoughts and different life styles. The computer games industry also acts as an influential medium in changing user behavior so as to form our cognition and perception of the world by constructing, transferring and recurring a variety of representations. In reviewing media texts, the ideological elements existing beyond them and the way they affect the audience's insight must be seriously addressed. In recent years, we have been witnessing a critical focus on Moslems' image in Western Media and computer games, in specific. This article has an attempt to investigate figurative representation of Arabs and Moslems, narrative structure and games stages in order for studying the methods of imaging of Arabs and Moslems in computer games. So, 7 ideological computer games produced in recent years regarding Moslems and Islam were examined using semiotic analysis qualitative method. Here, an integrative approach is conducted in which Stewart Hall's representation theories are at the center of theoretical debates and then Edward Said's insight into Orientalism is presented as an instance of representation theory application. We conclude that-in a complex integrative movement-Global Imperialism tries to create a sort of Islam-phobia in public opinion across the world and represents its own desirable image of Islam and Islamic civilization in mind of the audience.


A nursery sprayer based on a recycling principle was developed, constructed and then compared to a conventional tractor sprayer. With the recycling sprayer, pesticide suspension is more precisely directed onto the seedlings than with the conventional sprayer. During pesticide application on pine (Pinus sylvestris) seedlings with the recycling sprayer, between 40–90% of the pesticide is collected back into the tank. With the recycling sprayer, a smaller amount of pesticides is needed for equal spray coverage to that of the conventional tractor sprayer. Thus, the recycling sprayer reduces the costs of pesticide and also minimizes the contamination of the ground. However, the boom reach is shorter and therefore it takes longer to treat a given area resulting in a final cost that is equal or higher than with a conventional tractor sprayer. The occupational hygienic survey as well as biological monitoring revealed that the exposure of workers to pesticide did not differ during the recycling spraying and the co...


Rabies is a neurological disease, but the rabies virus spread to several organs outside the central nervous system (CNS). The rabies virus antigen or RNA has been identified from the salivary glands, the lungs, the kidneys, the heart and the liver. This work aimed to identify the presence of the rabies virus in non-neuronal organs from naturally-infected vampire bats and to study the rabies virus in the salivary glands of healthy vampire bats. Out of the five bats that were positive for rabies in the CNS, by fluorescent antibody test (FAT), viral isolation in N2A cells and reverse transcription - polymerase chain reaction (RT-PCR), 100% (5/5) were positive for rabies in samples of the tongue and the heart, 80% (4/5) in the kidneys, 40% (2/5) in samples of the salivary glands and the lungs, and 20% (1/5) in the liver by RT-PCR test. All the nine bats that were negative for rabies in the CNS, by FAT, viral isolation and RT-PCR were negative for rabies in the salivary glands by RT-PCR test. Possible consequences for rabies epidemiology and pathogenesis are discussed in this work.

problem and its historical background. The progression from institutional care to community-based service delivery is shown to be a marriage of convenience between a community treatment philosophy and a governmental cost-saving strategy. The second theme is devoted to a description of the rise and fall of the service-dependent ghetto and the growth of misassignment and homelessness. It is suggested that the sheer enormity ofthe task of provid ing comprehensive community-based services was never properly articulated or thought through, with the result that clients have searched in vain for the promised corn munity care. The authors see the danger of widespread re-institutionalisation becoming the new policy thrust. The third inter-related theme is the exploration of the public dilemmas surrounding community-based care for the dependent. De-institutionalisation is seen as a necessary stage in the evolution of modern humane services while re-institutionalisation, except for a small number of service-dependent people, is considered retrograde. Finally, the authors suggest specific ways in which neighbourhood communities may assist in solving the problems ofthe service-dependent. While their analysis of the problems of the marginalised population is masterly, their suggested solutions are unlikely to be realised. Nonetheless, this is a thought-provoking book which will inform the debate on the best ways to develop a humane welfare system. It will be of value to students of the social sciences and of interest to planners and policy-makers.


We conducted a study on one hundred and sixty four (164)  on-remunerated blood donors in the National Blood Transfusion Centre (CNTS) in Lome to evaluate the place of the alanine aminotransferases determination in the prevention of post transfusion hepatitis. Goals: - to determine alanine aminotransferase (ALAT) activity in the serum of blood donors, - to compare the rate of ALAT with the serological status of donors towards hepatitis B and C, - to conclude about the usefulness of ALAT in the blood safety towards hepatitis. Methodology : A transversal study from January to June 2005 was done on 164 blood donors in the CNTS of Lome. We determined ALAT activity on a sample of serum in the laboratory of biochemistry of the Campus Teaching Hospital of Lome and we screened donors towards hepatitis B and C by ELISA assay in the laboratory of serology of the CNTS. We compared the results of serology to the rate of ALAT activity. Results : Blood donors were in a large majority young (18 to 29 years old) with a predominance of male (sex ratio of 3.73). Assays for screening of hepatitis allowed eliminating 15.85 per cent of the donors for hepatitis B, 4.27 per cent for hepatitis C and 1.22 per cent for both hepatitis B and C. Two donors had high ALAT activity and in the same way were positive to hepatitis B. Conclusion : Donors who would have been eliminated for high ALAT activity had been already eliminated by the positivity to hepatitis B virus markers. The serological assays' performance seems to deny all interest to the ALAT determination in the blood safety. Nous avons mene une etude sur 164 donneurs de sang benevoles au Centre National de Transfusion Sanguine (CNTS) de Lome pour evaluer la place de la mesure de l'activite des transaminases de type alanine-aminotransferases (ALAT) dans la prevention des hepatites post transfusionnelles. Objectifs :- mesurer l'activite des transaminases de type ALAT chez les donneurs de sang ; - comparer les valeurs de ces transaminases au statut serologique vis-a-vis des virus des hepatites B et C ; - tirer des conclusions quant a l'utilite du dosage des transaminases dans l'amelioration de la securite transfusionnelle. Methodologie : Etude transversale de janvier a juin 2005 sur 164 donneurs de sang du CNTS de Lome avec dosage des transaminases sur un echantillon de serum au laboratoire de biochimie du CHU-Campus et tests ELISA de depistage de l'infection par les virus des hepatites B et C au laboratoire de serologie du CNTS. Les resultats biochimiques sont confrontes a ceux de la serologie. Resultats : La population des donneurs est en majorite jeune (18-29 ans) avec une predominance du sexe masculin (sexe ratio de 3.73). Les tests de depistages des hepatites ont permis d'eliminer 15.85% de donneurs pour cause d'hepatite B, 4.27% pour hepatite C et 1.22 % pour co-infection par les deux virus. Parmi ces donneurs infectes, deux (soit 1.22 % des donneurs de l'etude) ont eu des taux eleves d'ALAT et portent l'Ag HBs. Conclusion : Les donneurs qui auraient pu etre elimines pour ALAT elevees ont tous une serologie positive a l'Ag HBs de l'hepatite B et auraient donc pu etre elimines en l'absence du dosage des transaminases. La performance des tests serologiques actuels semble enlever au dosage des transaminases son interet dans la securite transfusionnelle.


George Saunders is an American short story writer. His writings include moral sting and stints of realism. This article is an analysis of one of his famous stories The Semplica-Girl Diaries. The story is a fine example of hedonism which means favouring pleasure and avoiding pain. This article speculates the idea of hedonism in the characters of this story and brings forth the theme of moral myopia. Hedonistic treadmill was at multiple times was being operated by those characters who try to own pleasure in spite of biting bullets. The other elements like American dream and consumerism have been analysed through the lens of narrator.


The article deals with the history of formal agricultural credit in Tanzania during the first years of independence, up to the Arusha Declaration in 1967. During this period greater efforts than hitherto were made to reach the small African farmer and make him switch to improved methods of production. The period also saw the emergence of national policies in the monetary sector. Some old credit institutions were abolished and new ones were established. The foundations were laid for present rural lending policies. In quantitative terms little was achieved, however. In 1967-68 no more than 4,5 percent of all loans to rural households came from, inadequately functioning, public institutions.


Inherited neuromuscular disorders (NMD) are chronic genetic diseases posing a significant burden on patients and the health care system. Despite tremendous research and clinical efforts, the molecular causes remain unknown for nearly half of the patients, due to genetic heterogeneity and conventional molecular diagnosis based on a gene-by-gene approach. We aimed to test next generation sequencing (NGS) as an efficient and cost- effective strategy to accelerate patient diagnosis. We designed a capture library to target the coding and splice site sequences of all known NMD genes and used NGS and DNA multiplexing to retrieve the pathogenic mutations in patients with heterogeneous NMD with or without known mutations. We retrieved all known mutations, including point mutations and small indels, intronic and exonic mutations, and a large deletion in a patient with Duchenne muscular dystrophy, validating the sensitivity and repro- ducibility of this strategy on a heterogeneous subset of NMD with different genetic inheritance. Most pathogenic mutations were ranked on top in our blind bioinformatic


ABSTRACT The unit cell dimensions of vanadium, NaCl and Au have been collected to 11. 5 GPa and 1000 K by powder X-ray diffraction and are used to constrain a practical high-temperature EoS for bcc vanadium. The resulting third-order Birch–Murnaghan EoS is described with parameters KT0,300 = 150.4 ± 6.2 GPa,  = 5.5 ± 1.0, α0 = 4.8(6)·10−5, α1 = −2.4(9)·10−8 and δKTδT = −0.0446(7) GPa/K. The parameter α.K0,300 is 616·10−5 K−1 GPa and reduces to zero at an estimated 60 GPa at RT. This EoS description is entirely consistent with the majority of X-ray, ultrasonic, shock wave and calculated data-sets in this p, T range. These measurements facilitate the estimation of in situ temperatures under high pressures when vanadium is used inside sample assemblies and are useful, when used with h-BN, to estimate p, T over the full range of h-BN stability.


Preface Let ξ be a smooth principal G-bundle over a differential manifold B representing a physical theory. An equivariant, fibre preserving bundle automorphism of ξ gives rise to a new bundle with identical physical content and therefore, such an automorphism is a symmetry of the physical theory. It is clear that the set G(ξ) of all such automorphisms (called gauge transformations) has the algebraic structure of a group; it has also a topological structure compatible with the group structure, that is to say, G(ξ) is a topological group (see Section 2.1) called gauge group of ξ. The gauge group G(ξ) acts on the connections and curvature forms; the attempt to understand these objects under the action of the gauge group lead to the development of a new theory known as Gauge Theory. Born in the framework of Theoretical Physics, gauge theory soon became an important and powerful research instrument also in Differential Geometry, leading to the construction of new invariants. On the other hand, gauge groups are interesting topological and algebraic objects on their own right. Moreover , they can be viewed as particular cases in more general contexts as, for example, in the study of the group of homotopy classes of fibre preserving self-homotopy equivalences of a fibration. Indeed, from this point of view, gauge groups are just a particular case of a far more general abstract situation: they can be regarded as coming from the self-equivalences of an object within a well-defined Category. The general line of thought in these notes is the classical one followed rather successfuly in Algebraic Topology: we associate algebraic objects to fibre bundles, and through some algebraic properties of the former we try to obtain topological informations about the latter. Now, gauge groups contain interesting informations about the topology of the bundles; thus, it seems rather natural to search for these topological properties through algebraic manipulations of the gauge groups. A direct analysis and classification of 5 6 CONTENTS gauge groups as algebraic objects is rather complicated; a simpler way seems to be the comparison of the gauge groups of different bundles within a larger group of symmetries. Let us explain this last idea more thoroughly. Fibre bundles are locally trivial over the open sets U i of a convenient open covering of B, that is to say, the restriction of ξ over each U i behaves like a projection U i ×G …


Background:  Recent studies have shown that CD40, a key player in angiogenesis and tubular formation, is an extracellular receptor of the heat shock protein 70 (HSP70)–peptide complex in endothelial cells.

Specific propellant management system requirements have been identified for each facility category of SSF. Distributed systems have been analyzed to indentify momentum management, guidance, and traffic management requirements associated with the guidance, navigation, and control system; space-to-space communications and enhanced tracking requirements associated with the communications and tracking system; and propellant management system utility requirements associated with the electrical power system. Flight element analyses determined attach structure, utility distribution, and structural integrity requirements for the pre-integrated truss and high mass manipulation and translation requirements for the mobile base system.


In a sheared magnetic field, turbulent diffusion of electrons in the vicinity of a mode rational surface can eliminate the stabilizing influence of nonresonant electrons and lead to an absolute instability at small but nonzero wave amplitudes. As the turbulence grows, the inverse electron Landau resonance is broadened in both velocity and configuration space, and the convective shear damping due to ions is enhanced by turbulent spatial broadening of the mode until saturation occurs.


The protein EPHB4 plays a vital role in various tumor types. However, few studies into the function of circ‐EPHB4 (hsa_circ_0001730) in tumors have been conducted. This study aimed to investigate the functions of circ‐EPHB4 and the underlying mechanism of circ‐EPHB4 in regulating hepatocellular carcinoma (HCC). The expression of circ‐EPHB4 was found to be downregulated in HCC tumor tissues, whereas circ‐EPHB4 overexpression suppressed cell viability, induced apoptosis, and inhibited cell migration and invasion in Huh7 and HepG2 cells. circ‐EPHB4 levels were negatively correlated with tumor weight, size, and metastasis foci in nude mouse models, suggesting circ‐EPHB4 inhibits tumorigenesis, tumor development, and metastasis. In addition, HIF‐1α and PI3K–AKT pathways were markedly affected by circ‐EPHB4 overexpression. HIF‐1α could potentially be the target of circ‐EPHB4. By overexpressing both HIF‐1α and circ‐EPHB4, the antitumor effect of circ‐EPHB4 should be most probably correlated with HIF‐1α. In conclusion, circ‐EPHB4 is a tumor inhibitor in HCC and functions by inhibiting HIF‐1α expression.


To improve the stability and controllability of vehicles, especially for wheel-driven field robot system, the friction between tire and road are investigated. For the commercial vehicle, various techniques including vehicle dynamic control, traction control, and anti-lock braking system have been developed and adopted. To accomplish these systems, the most important factor is to estimate the tire-road friction characteristics. Most of the tire-road friction estimation algorithms are based on the tire slip ratio and the tracking force obtained by a tire model. However, because the slip ratio and tracking force are difficult to be measured directly and defined strictly, additional estimation algorithms to get these values are required. Therefore, in this paper, in the view of traditional friction definition, we propose a tire-road friction estimation method that uses the traditional friction model. Also, to get normal force for the vehicle system, dynamic force distribution algorithm is suggested. The real car experimental result shows good performance of the proposed methodology.

Objective: Dual x-ray absorptiometry (DXA) is gold standard of bone densitometry, but quantitative ultrasound (QUS) of bone is less expensive and portable. This study was designed to assess its usefulness in secondary osteoporosis diagnosis. Materials and Methods: There were 200 secondary osteoporosis cases (rheumatoid arthritis, hemodialysis, kidney transplant patients, and levothyroxine users) and of those, their phalanx QUS results were compared with normal controls. Also, the QUS and DXA results were compared to find any correlation of these methods for diagnosing osteoporosis. Results: There was not significantly different results compared with normal controls, except for those of hemodialysis patients (P = .00). Also, the comparison of QUS with DXA results showed no significant correlation except in hemodialysis patients, in both spinal and femoral regions (P = .023 and .21, respectively), as well as the levothyroxine group's spinal region (P = .005). Conclusion: These results suggest that QUS of phalanx may be useful in screening secondary osteoporosis but for establishment of diagnosis, DXA measurements are still needed.


The streptothricin group of antibiotics produced by various Streptomyces strains are potent inhibitors of prokaryotic protein synthesis with a broad antibacterial spectrum. Chemical acetylation of the /3-amino group of the /3-lysine moiety in streptothricins caused loss of their antibacterial activity1}. Acetyltransferase activity encoded by a plasmid-born streptothricin-resistance gene was detected in Escherichia coli2\ however, neither purification of the enzymenor structural identification of the acetylated product has yet been performed. The presence of the acetyltransferase activity in streptothricin-producing Streptomyces strains was reported3*40. We have cloned a streptothricin-resistance gene from Streptomyces lavendulae No. 1080, one of the streptothricin-producing microorganisms, into Streptomyces lividans^ and constructed a cloning vector pKST2containing the gene as a selective marker5). This paper deals with purification and characterization of the streptothricin acetyltransferase (STAT) encoded by the cloned resistance gene and identification of its reaction product, acetylstreptothricin F.


Accelerated bridge construction (ABC) using full-depth precast deck panels is an innovative technique that brings all the benefits listed under ABC to full fruition. However, this technique needs to be evaluated and the performance of the bridge needs to be monitored. Sensor networks, also known as health monitoring systems, can aid in the determination of the true reliability and performance of a structure by developing models that predict structure behavior and component interaction. The continuous monitoring of bridge deck health can provide certain stress signatures at the onset of deterioration. The signatures are vital to identify type of distress and to initiate corrective measures immediately; as a result, bridge service life increases and eliminates costly repairs. This project focused on the continuous monitoring and evaluation of the structural behavior of the Parkview Bridge full-depth deck panels under loads using the sensor network installed. Special attention was placed on the durability performance of the connections between precast components. However, after careful evaluation of the designs and construction process, it was identified that the transverse joints between deck panels are the weakest links, in terms of durability, in the system. Analysis of sensor data and load test data showed that the live load effect on the bridge is negligible. The dominant load is the thermal. Using three years of data from the sensors, stress envelopes were developed. These envelopes serve as the basis for identifying the onset of bridge deterioration. A detailed finite element (FE) model was developed, and the model was first calibrated using load test data. However, due to the dominance of thermal loads, it was required to calibrate the model using stresses developed in the structural system due to thermal loads. This was a great challenge due to a lack of sensors along depth of the bridge superstructure cross-section. A few models were identified that are capable of representing the thermal gradient profile from 12 p.m. to 6 p.m. in a summer day. The FE model was calibrated using sensor data and the thermal gradient profile of the specific duration. Construction process simulation with the calibrated model shows that all the joints between the panels are in compression, as expected at the design. Stress signatures were developed simulating the debonding of a transverse joint between panels. The signatures show a distinct pattern than what is observed from a bridge without distress. Hence, the onset of deterioration can be identified from the sensor data to make necessary maintenance decisions. The proposed signatures are applicable only during 12 p.m. to 6 p.m. on a summer day, and development of deterioration models for the rest of the time requires development of new thermal models. Further, the stresses vary drastically following onset of joint deterioration; hence, identification of exact physical location of the sensors is required for fine-tuning the models.


In order to improve the understanding of the phenomena underlying the boiling occurrence, CEA Cadarache (France) is designing a new experimental setup, intended to operate for pressures ranging from atmospheric to PWR conditions. This will allow optical access to the convective boiling flow as well as thermal imaging (infrared thermography) of the heated surface. A two-step methodology for designing the heater (particularly its thickness since it directly influences the boiling mechanisms) was developed. This approach is based on solving the heat conduction problem within the heater, considering realistic time-dependent boundary conditions representative of the boiling process. Since those boundary conditions are measured on the external face of the heater, this heat transfer problem is known as an inverse problem that is difficult to solve because of its ill-posedness and high sensitivity to boundary condition uncertainties. In the first stage, we considered one-dimensional modeling to determine the order of magnitude of the heater's thickness that guaranteed a correct reconstruction of the wet temperature from the measured dry temperature in terms of uncertainties. This value was confirmed in the second stage using a two-dimensional model that accounted for the presence of multiple bubbles on the wet side.

The objective of this research is to determine whether there is a significant effect of using the Inquiry teaching method on students' vocabulary achievement among the seventh-grade students of SMP Negeri 1 Barumun. The population of this research is the seventh-grade students of SMP Negeri 1 Barumun, which consists of 54 students, and the sample was taken by cluster sampling composed of 27 students. This research is carried out by using experimental methods. The test is used as the instrument of this research, after collecting the data, it was analyzed using the t.test formula. The data analysis found that the mean or average of students' scores after the treatment is 80.55. Using the statistical analysis, the researchers get to 28.80, where the value of t.table  is 2.05. It means that the value of t observed is greater than that of the t table (to = 28.80> t table = 2.05). The calculation of the coefficient of determination is 0.84, which means the inquiry teaching method affected students' vocabulary achievement by as much as 84%. It means that the Inquiry teaching method significantly affects teaching vocabulary. The alternative hypothesis of this research is accepted, and the Inquiry teaching method can be applied in the classroom to increase the student's vocabulary achievement.


Final-energy sum rules are used to calculate the proton coupling constant lambda/sub p/ with an interpolating proton current. The coupling constant lambda/sub p/ can be used to calculate the matrix elements for proton decay in the grand unified SU(5) model. The proton lifetime is calculated to be tau/sub p/ = 10/sup 28/ x (M/sub X//10/sup 14/ GeV)/sup 4/ yr, where M/sub X/ is the mass of the X boson.

How to optimize and schedule hundreds of traffic lights has become a challenging and pressing problem. The key point lies on how to manage them dynamically and timely. This paper proposes an inner and outer cellular automaton mechanism combined with particle swa445rm optimization (IOCA-PSO) method to achieve a dynamic and real-time optimization scheduling of urban traffic lights. The proposed IOCA-PSO method includes three parts: the inner cellular model (ICM), the outer cellular model (OCM), and the fitness function. Our main contributions lie on three points: (1) The concise basic transition rules and affiliated transition rules are proposed in ICM, which help to achieve a global sophisticated scheduling. (2) The proposed inner and outer cellular PSO (IOPSO) algorithm in OCM offers a strong search ability to find the optimal timing scheduling. (3) The proposed fitness function can evaluate and conduct the optimization of the traffic light scheduling dynamically for different aims. Extensive experiments in real cases show that the IOCA-PSO method has distinct improvements under different traffic conditions.


Recent advancement in numerical techniques for Vlasov simulations and their application to cross-scale coupling in the plasma universe are discussed. Magnetohydrodynamic (MHD) simulations are now widely used for numerical modeling of global and macroscopic phenomena. In the framework of the MHD approximation, however, diffusion coefficients such as resistivity and adiabatic index are given from empirical models. Thus there are recent attempts to understand first-principle kinetic processes in macroscopic phenomena, such as magnetic reconnection and the Kelvin–Helmholtz (KH) instability via full kinetic particle-in-cell and Vlasov codes. In the present study, a benchmark test for a new four-dimensional full electromagnetic Vlasov code is performed. First, the computational speed of the Vlasov code is measured and a linear performance scaling is obtained on a massively parallel supercomputer with more than 12 000 cores. Second, a first-principle Vlasov simulation of the KH instability is performed in order ...


To explore the effect of exogenous H2O2 on antioxidant enzymes and other physiological indexes of wheat seedlings under lead stress,wheat seedlings cultivated in solution with different concentration of H2O2 were used to observe the variation of activity of peroxidase(POD),superoxide dismutase(SOD),catalase(CAT) and content of malondialdehyde(MDA),root activity and micronucleus rate.The results showed that wheat seedlings were chronically harmed under heavy metal stress,as vigor of wheat seedling root decreased;POD,SOD,CAT activity and MDA content,micronucleus rate increased.After being treated by H2O2 with appropriate concentration,POD,SOD,CAT activity,root vigor increased while MDA content and micronucleus rate decreased in wheat seedlings under lead stress compared to control,indicating that exogenous H2O2 could reduce the damage caused by lead stress.


The rationale of this research was to prepare a gastroretentive drug
delivery system of Ranitidine HCl. Floating Drug delivery system used to
target drug release in the stomach or to the upper part of the intestine.
Currently, floating tablets are one of the important catagories of drug
delivery systems with gastric retentive behavior. Ranitidine is a H2 blocker,
absorbed from the upper part of gastrointestinal track, and metabolized in
the colon that can degrade the drug, leading to a low bioavailability. Hence
there is need to develop a dosage form that release the drug in stomach so
that it can be absorbed from upper part of gastrointestinal track leading to
improved bioavailability.
Four different formulas of ranitidine HCl were prepared by wet
granulation method using 20% of hydroxypropyl methylcellulose (HPMC)
K4M and HPMC K100M. The ratio of hydroxypropyl methylcellulose K4M
and hydroxypropyl methylcellulose K100M in F1, F2, F3, and F4 is 1:0,
1:2, 1:4, 1:6 respectively. The prepared tablets were evaluated on their
floating and drug release characteristics. The dissolution test was performed
using 900 ml of 0,1 N hydrochloric acid, at 37 ± 0,5°C and 50 rpm.
The result showed that the Floating lag time, it is a floating
characteristic is improving as the increasing concentration of HPMC
K100M in formula's ratio. The kinetic release of all formulas followed both
first order and Higuchi's model and the release mechanism dominated by
non-fick diffusion.


Sir.—In premature infants, hypercalciuria has been previously described in association with either hypophosphatemia or furosemide therapy.1,2However, to our knowledge the simultaneous presence of these two calciuric stimuli in the same patient and their relative contribution to increased urinary calcium excretion have not been reported previously. Patient Report.—An 830-g male infant was born at 27 weeks' gestation. His hospital course was complicated by respiratory distress syndrome and pharmacologic closure of a patent ductus arteriosus with indomethacin on day 5 of life. Feeding with commercial milk formula (calcium, 790 mg/dL; phosphorus, 398 mg/L) for premature infants was started on day 6, and the patient was receiving full enteral feeding by day 23, providing him with 150 mL/kg/d and 504 kJ/kg/d (120 kcal/kg/d). Daily intakes of calcium and phosphorus were 118 mg/kg and 59 mg/kg, respectively. Weight gain averaged between 10 and 15 g/d after the first month of


Abstract Evidence relating peculiar contrast effects observed in 0002 dark field diffraction contrast images of multishell carbon nanotubes, and the presence of singular interplanar spacings in the tubule wall is presented. The singular spacings are most probably due to the presence of scrolls in the tube.


Single bud stem of superior individual Juglans sigillata cv.'Nayong-1' were used as explants to establish in vitro culture and rapid propagation system.Results showed that the DKW medium supplemented with 1.0 mg·L~(-1) 6-BA+3.0 g·L~(-1) AC was suitable for germination of axillary buds.The DKW medium with 1.0mg·L~(-1) 6-BA+0.02 mg·L~(-1) IBA was optimal for the shoots multiplication,the proliferation coefficient was up to7.33 after culturing for 40 days.Both shoot tip and single axillary bud could be used for multiplication culture.One step method(low IBA concentration sustained induction) was not suitable for rooting culture.The highest rooting rate(71.73%) was obtained by two steps method,firstly the plantlets was cultured on 1/4DKW medium with 5.0 mg·L~(-1) IBA in the dark condition for 12 days,and then transferred to the 1/4DKW medium without IBA under light(3 g·L~(-1) AC and 20 g·L~(-1) sucrose).It was found that the IBA concentrations,time of dark induction,sucrose concentrations and AC contents were all related to the effect of rooting.After acclimation in pearlite and nutrient soil for 60 days,87.50%plantlets were survival.


The decay of Lambda(b) --> Sigma(c)((*)) pi/ processes is calculated in the framework of heavy baryon chiral perturbation theory with the help of the 1/N-c expansion. The decay rate distributions over nu . nu' where nu and nu' are the four-vector velocities of Lambda(b) and Sigma(c)((*)), respectively, and over the pion and lepton energies, are given. The decay branching ratios amount to about 1.21(0.971)% for Lambda(b)-->Sigma(c) pi/ and 0.798(0.640)% for Lambda(b)-->Sigma(c)* pi/ by using the baryonic Isgur-Wise function predicted by QCD sum rules (large N-c QCD).


Earthquake is one of the most threatening natural disasters which is caused due to the shaking of the earth's surface. Common cause of earthquake is due to ground shaking, underground volcanic eruption. Here, XGBoost Algorithm is used to predict the location of the earthquake. In this paper, a earthquake location prediction method is proposed, which is based on the composition of a known system whose behaviour is administered according to the evaluation of more than two decades of seismic events and is designed as a time series using Machine learning.

In this paper, we calibrate Mirtich's approach (1996) for computing a collision impulse by two kinds of randomized algorithms, and then apply the model for an air hockey game. Mirtich proposed a smart dynamic simulation called impulse-based simulation. He considers twin goals of physical accuracy and computational efficiency. The simulation can accurately model complex dynamic system in real-time. However, whether his impulse-based model is reasonable or not has not been investigated at all by any experimental result. For example, his impulse model requires the dynamic friction coefficient /spl mu//sub D/ and the coefficient e of restitution in advance. However, they strongly depend on shape and material of colliding objects. Because of noise and error of sensing, it is difficult for us to measure the parameters exactly. For this reason, in this paper, we calibrate these by using two kinds of randomized algorithms based on many reductions of momentums before and after the collision. Each momentum (multiplying mass and velocity) can be easily obtained by measuring relative linear velocities and angular velocities before and after the collision. They are practically and easily measured by a smart imaging of two objects. The air hockey game designed consists of two PC with two joysticks including force feedback, which are connecting each other by the fast Ethernet.


The kinetics and mechanism of the rod-to-vesicle transition in aggregates of polystyrene310-b-poly(acrylic acid)52 diblock copolymers in dioxane/water mixtures are explored. The transition is induced by a jump in the water content from a point at which the morphologies are under equilibrium control. The transition mechanism is monitored by transmission electron microscopy (TEM). The transition intermediates are trapped by quenching solution samples to liquid nitrogen temperature and then preserving the aggregate morphologies using the freeze-drying technique. It is shown that the morphological transition goes through a lamellar intermediate state. The corresponding kinetic data are obtained from turbidity measurements. The analysis of the plot of turbidity versus time suggests two consecutive first order steps. The first step appears to be the flattening of short rods in favor of irregularly shaped or circular lamellae, which are the intermediate morphologies observed using TEM. The second step involves t...
