A tracer technique was developed for measuring the wear of cylinder liners in engines. In the technique development a 42-in.-long 160-lb cylinder liner, designed for a 8 1/8 x 10-in. opposed piston diesel engine, was irradiated in a pool reactor at the inner-dead-center-ring travel where maximum wear occurs. The 300-day Mn/sup 54/ was formed by neutron activation of Fe/sup 54/together with small amounts of re/sup 59/and Cr/sup 51/. Handling and healthphysics procedures involved in the transportation of the irradiated liner and installation in the engine are described. Radioassay techniques were developed for analyzing wear products in both the lubricating oil and exhaust gas, using an immersion scintillation crystal detector coupled with a precision scaler for the lube oil and a scintillation well counter for the gas. The precision of the tracer technique was determined by comparing tracer-measured wear witb micrometer- measured actual wear. (D.L.C.)


The surface oxidation of tungsten is a serious issue in plasma processing of advanced integrated-circuit devices where tungsten is being used as a gate electrode. In this article, we study tungsten oxidation in O2∕H2∕N2 downstream plasma at a temperature ⩽300°C. The results show that oxidation occurs rapidly in O2 downstream plasma to form stable WO3. However, oxidation can be reduced effectively by adding H2 and totally suppressed when H2 concentration in the gas feed reaches a certain low level at which the plasma is still oxygen dominant. Tungsten oxidation increases significantly with sample temperature and exposure time in O2 downstream plasma. However, H2 addition reduces both temperature and time dependences due to the coexistence and competition of oxidation and reduction processes. When N2 is also added, the efficiency of H2 in O2 downstream plasma in controlling tungsten oxidation is lowered. The findings may provide effective approaches to various applications of selective oxidation over tungst...

: Identification of the factors that shape the effectiveness of innovation activities is important for promoting regional development. The paper aims at evaluation of determinants of innovation performance in the European regions. In order to investigate this issue we apply a fixed effects regression model on a 5-year longitudinal dataset of 190 European regions. We explore four groups of determinants of innovation performance: technological innovation capital, non-technological innovation capital, human capital and network capital of regions. In order to assess regional innovation performance we use a variable measuring the relative ability of firms to generate revenues from sales of product or process innovations. The results of analysis indicate that all examined forms of regional innovation capital exert positive and statistically significant impact on innovation performance, except human capital for which our evidence seems ambiguous. The strongest impact on the relative ability to generate revenues from sales of innovations seems to be exerted by the technological innovation capital (measured by intensity of public sector R&D expenditures), closely followed by non-techno-logical innovation capital (measured by the non-R&D innovation expenditures in firms). Our results also demonstrate a somewhat weaker, positive influence of collaboration on innovative activities (used as a proxy of network capital) on the aforementioned firms' revenues. Surprisingly, human capital (measured by the share of population aged 25-64 with tertiary education attainment) turned out to have positive but statistically insignificant impact on innovation performance.


Onion peel and Zn(CH3COO)2. 2H2O were used as a starting material for the synthesis of zinc oxide nanoparticles (ZnONPs). The formation of ZnONPs was first observed by changing the color of the Zn(CH3COO)2. 2H2O solution from colorless to yellow. The Zn-extract solution was tested by a UV-Vi spectrophotometer, and the maximum absorbance peak formation at 362 nm, which belongs to ZnONPs, was observed. For the synthesis of ZnONPs, the optimum Zn(CH3COO)2. 2H2O concentration was determined to be 0.2 M, the optimum temperature was 60C, the optimum pH was 12.0, and the optimum extract volume was 10 mL. The formation of ZnONPs was identified with the evaluation of SEM images and UV spectra. It was shown that agricultural wastes are re-used and onion peel waste is suitable for the production of ZnONPs.


The invention relates to a method for detecting micro 4-methoxyphenol. The method is mainly used for detecting the micro 4-methoxyphenol in an unsaturated monomer. The method is characterized by: carrying out pre-treatment for an unsaturated monomer sample requiring detection; then adding an acetic acid-sodium acetate buffer solution; then adding a proper amount of 1,10-phenanthroline and an ammonium ferric sulfate regent, wherein the Fe is reduced through the 4-methoxyphenol in the sample and the reduced Fe forms a red complex with the 1,10-phenanthroline; adopting a spectrophotometer to detect the absorbance of the complex at a wave length of 510 nm; calculating the 4-methoxyphenol content in the sample according to a work curve, wherein the work curve is obtain through the following steps: dissolving the 4-methoxyphenol in butyl acetate, then detecting the 4-methoxyphenol content in the butyl acetate through the 1,10-phenanthroline and the ammonium ferric sulfate to obtain the work curve. The method provided by the present invention has good stability. In addition, the yellow interference due to the unsaturated monomer can be removed, such that the detection is more accurate.


The eddy current distribution arising from stator and rotor decrement tests are calculated in the cross -section of a 333 MVA 4-pole generator. The stator winding is represented by an equivalent current sheet, voltages in it being calculated from a two-axis consideration of the air-gap field, Coupling equations for the field in the machine and the windings are formulated with the nodal method and eddy currents and field distributions are obtained in a step-by-step calculation using a Newton-Raphson technique. Saturation of the steel is allowed for within each element. Results are shown for the eddy current distribution when the machine is excited (i) from the 3-phase supply and (ii) from the field winding, and the excitation is suddenly removed. The eddy current patterns generated indicate the different nature of these two transient conditions and confirms the need for d-axis equivalent circuits containing a representation of damping circuits asymmetrical to the field and stator winding.

We present in situ sputtering yield measurements of the time-dependent erosion of flat and micro-architectured molybdenum samples in a plasma environment. The measurements are performed using the plasma interactions (Pi) Facility at UCLA, which focuses a magnetized hollow cathode plasma to a material target with an exposure diameter of approximately 1.5 cm. During plasma exposure, a scanning quartz crystal microbalance (QCM) provides angular sputtering profiles that are integrated to estimate the total sputtering yield. This technique is validated to within the scatter of previous experimental data for a planar molybdenum target exposed to argon ion energies from 100 to 300 eV. The QCM is then used to obtain in situ measurements during a 17 h exposure of a micro-architectured-surface molybdenum sample to 300 eV incident argon ions. The time-dependent angular sputtering profile is shown to deviate from classical planar profiles, demonstrating the unique temporal and spatial sputtering effects of micro-architectured materials. Notably, the sputtering yield for the micro-architectured sample is initially much less than that for planar molybdenum, but then gradually asymptotes to the value for planar molybdenum after approximately 10 h as the surface features are eroded away.


Objective: To determine how implementing a systematic medication therapy management (MTM) process impacted MTM completion rates. Methods: This process improvement pilot included 4 grocery store-based community pharmacy sites. Site staff were trained on a systematic process to integrate OutcomesMTM opportunities into pharmacy workflow. Technicians prepared MTM paperwork, including a standardized comprehensive medication review (CMR) worksheet, which pharmacists used to deliver the service at the counsel window. The primary outcome was the change in CMR completion rate from pre- to post implementation, with each site serving as its own control. Secondary outcomes were change in targeted intervention program (TIP) completion rate and survey results assessing barriers and feasibility. Results: The mean CMR completion rate improved from 2.7% ± 5.4% to 23.2% ± 7.7% (P < .10). The mean TIP completion rate improved from 3.4% ± 4.2% to 24.9% ± 19.2% (P < 0.10) pre- to post-implementation. Survey results indicated that pharmacists were satisfied with this; the most significant barriers were time spent contacting prescribers, documentation, and claim submission. Conclusion: Implementing this systematic approach to providing MTM into the pharmacy workflow may lead to an improvement in CMR completion rate. However, the sample size is small, and the results and process may not be generalizable to other sites.


In this paper, an improved long short-term memory (LSTM)-based deep neural network structure is proposed for learning variable-length Chinese sentence semantic similarities. Siamese LSTM, a sequence-insensitive deep neural network model, has a limited ability to capture the semantics of natural language because it has difficulty explaining semantic differences based on the differences in syntactic structures or word order in a sentence. Therefore, the proposed model integrates the syntactic component features of the words in the sentence into a word vector representation layer to express the syntactic structure information of the sentence and the interdependence between words. Moreover, a relative position embedding layer is introduced into the model, and the relative position of the words in the sentence is mapped to a high-dimensional space to capture the local position information of the words. With this model, a parallel structure is used to map two sentences into the same high-dimensional space to obtain a fixed-length sentence vector representation. After aggregation, the sentence similarity is computed in the output layer. Experiments with Chinese sentences show that the model can achieve good results in the calculation of the semantic similarity.


A method for accelerating a memory access of a memory page that is included in a memory bank in a multi-bank type memory (908) by a memory controller (904) is described. An incoming Systemadresanforderung is received from the memory controller (904) comprising a requested bank number and a requested page number. A page register number corresponding to the requested bank is then located, whereby the stored page address is included in the located page register is compared with the requested page address. then accesses the requested page in the memory bank corresponding to the requested bank number when the stored page address matches the requested page address for the requested memory bank.

The Bulk Image Transformation Engine (BITE), developed at International Imaging Systems, has been designed specifically to address the unique problems encountered in processing large, multi-band, image data-sets. The key elements of the hardware and software architecture that combine to provide an efficient, yet easy to program, solution to these problems will be discussed. A generalized image warping algorithm developed for the BITE illustrates the performance of this architecture on a real-world problem.


The resonance scattering theory (RST), originating from the theory of nuclear reactions, is a general approach to analyzing the resonance phenomena in scattering amplitude. The new RST that has recently been developed in the field of acoustics suggests that there are three interacting contributions: the resonance, the background, and their correlation. The moduli and phase of the resonance coefficient are obtained with the appropriate results through the new RST. In this paper, the new RST is applied to the two-dimensional scattering problem of electromagnetic waves for a dielectrically coated conducting cylinder, and the numerical result is shown.


n Australia, there are currently around 10,500 workers providing formal funded child care in either their homes or the homes of the children. They provide care for approximately 95,000 children countrywide and span across the many geographical regions o f the country. They provide care in both standard and non-standard hours. The purpose of this study is to determine the economic, social and institutional factors that determine the costs of providing family day care services (FDC) across geographical areas in Australia. The study was based on three sets of data: a web-based financial survey designed to elicit basic financial and activity data for the agencies. The survey was sent in mid 2008 to all national providers obtaining useable response rate of45%. The second data set was qualitative data obtained from in-depth interviews with 10% o f all FDC agencies. The last data source was administrative data from the Australia's Department of Employment, Education and Workplace Relations. Econometric analysis of expenditure by FDC agencies identified that expenses is largely determined by the number of full time equivalent places with organisational structure explaining 84% of the variation. Staff costs inclusive of on-cost account for just over 70 per cent o fall costs. Qualitative data identified recruitment of new careers, quality assurance and accreditation, training and supporting careers, with high needs children as the main cost drivers. The paper concludes by providing evidence of the important role that this sector plays in Australian childcare industry and examples o f innovative steps being undertaken by providers to ensure continued financial viability.


Triassic black mudstones are extensively distributed in Tarim basin with great thickness and higher content of total organic matter (TOC) and extractable organic matter (EOM). Abundance pregnanes and higher concentrations of tricyclic terpanes are also observed in extractable organic matter (EOM) of Triassic source rocks. All of above characteristics show that organic matters in Triassic source rocks of Tarim basin are rich in aquatic\|life derived organic material and Triassic source rocks are favorable for oil and gas generation. Triassic source rock organic matters are also mature in thermal maturity in most parts of Tarim basin. The oil/gas and source rocks correlation studying have proved that considerable amount of oil and natural gas produced in Tarim basin are derived from Triassic source rocks. Triassic source rocks are in good condition with relatively higher potential for oil and gas generation.


Discussions of the problem of the investment of trust funds are usually, and quite naturally, premised on the assumption that the trusts giving rise to the problem are of the conventional type. However, recent years have witnessed a significant departure from the customary trust in the development of the "Fixed-Income," "Annuity," and "Modernized" types of trust. Since resort to any of these trust forms presents for the trustee an investment problem quite different from that confronting him under a trust of the usual type, a comprehensive treatment of the trust investment problem calls for a consideration of these newer trust forms in relation to that problem. The "Fixed-Income," "Annuity" and "Modernized" types of trust differ slightly from each other. That difference will be explained near the end of this paper. The three of them join, however, in a common dissimilarity to the conventional trust in that the latter provides that earned income only shall go to the life tenant, the entire corpus supposedly to be conserved for the remaindermen. The "Fixed-Income," "Annuity" and "Modernized" types provide for stipulated payments to the life tenant regardless of what income may actually be earned. In treating the subject of the "Fixed-Income," "Annuity" and "Modernized" types of trust, the author assumes that this article may be read by both trustees and trustors, or at least by the latter's legal representatives. It shall be his aim, therefore, to discuss this type of trust from the point of view of its advantages both to trustees and to trust beneficiaries. The plan seems to harbor no disadvantage for either. Whence came the conventional, "earned-income-only to the life tenant" trust form, and how it could possibly have achieved such almost universal usage, it is apparently futile to speculate. Probably the first trusts were employed by wealthy testators whose estates were of adequate size to warrant this conventional form-that is, their earnings, even at low rates of interest, were ample to support the life tenant on the scale to which she was accustomed. When, however, this conventional form is employed for estates whose size is so small that earnings of 6%, 5% or even 4%

Rapid growth in the deployment of networked electronic control units (ECUs) and enhanced software features within automotive vehicles has occurred over the past two decades. This inevitably results in difficulties and complexity in in-vehicle network fault diagnostics. To overcome these problems, a framework for on-board in-vehicle network diagnostics has been proposed and its concept has previously been demonstrated through experiments. This paper presents a further implementation of network fault detection within the framework. Adaptive OSEK Network Management, a new technique for detecting network level faults, is presented. It is demonstrated in this paper that this technique provides more accurate fault detection and the capability to cover more fault scenarios.


In ballistic Josephson junctions the experimentally observed IV characteristics deviate from the theoretically predicted behavior. Recently, Heida et al. [Phys. Rev. B 60, 13 135 (1999)] discussed this problem and offered an explanation for the discrepancy. Considering this explanation, several contradictions to the authors' data as well as to other publications are shown.


Drug induced hepatitis due to anti-tuberculosis treatment is an important issue. Studies have shown that drug-induced hepatotoxicity is primarily due to oxidative stress caused by the anti-TB drugs and metabolites. A randomized clinical trial was conducted on 85 new TB patients who were aged 50 years or more. Informed consent was obtained from all patients and Patients were randomized in two groups. In control group (n=42), drug regimen included daily doses of ethambutol, pyrazinamide, isoniazid and rifampicin plus placebo. Patients in trial group (n=43) were treated with anti-TB drugs plus N-Acetyl Cysteine. The patients were followed up for 2 months and quality of life of patients measured by questionnaires of SF-12. Statistical analysis was performed using SPSS (statistical software package ver.16) and PValues less than 0.05 were considered significant. RESULTS showed that: This research showed demographic and disease characteristics of two groups such as gender, age, type of TB (pulmonary and extra-pulmonary), body mass index, laboratory characteristics of patients at the onset of treatment (CBC, ESR, CRP and liver enzymes) had no significant differences and were nearly the same. During treatment, there were significant differences between the two groups regarding the incidence of hepatitis and elevated liver enzymes. In addition, the clinical course and reduced CRP levels were different between them. Also the trial groups compared with the control group seems to have a better quality of life. CONCLUSION: N-Acetyl Cysteine prevented hepatotoxicity significantly and improved the patients' quality of life. With regard to effect of N-acetylcysteine and also low cost and lack of serious side effects we recommend that it be given with other anti-TB drugs during the first month of treatment.


Sol–gel materials prepared from organically-modified silanes are used for sequestration and reduction of Cr(VI). These sol–gels act as matrices for sequestration and reduction of Cr(VI) as well as binding of Cr(III) ions in the porous structure. Acid treated sol–gels obtained from bis[3-(trimethoxysilyl)propyl]ethylenediamine (EnTMOS) and 3-mercaptopropyltrimethoxysilane (SHTMOS) sequester and reduce Cr(VI) from an external solution. The removal of Cr(VI) from solution was monitored spectrophotometrically and the sol–gels were characterized with FTIR and TEM. The amino and thiol groups in the hybrid sol–gels play a critical role and the gels containing both these functional groups are considerably more effective at removal of Cr(VI) than those containing just one of these functional groups. Finally, the pH of the medium is also found to be an important parameter in kinetics and efficiency of removal of Cr(VI).


Although experimental work has shown that spermatia are effective as fertilizing agents in a number of Ascomycetes (Dodge, 1932; Ames, 1932; Drayton, 1932; Dimock, 1937; Groves and Drayton, 1937; and Zickler, 1934, 1937), the mechanism by which fusion between the spermatium and the receptive hyphae is effected has been shown in relatively few genera. Higgins (1936) illustrated the long, tapering trichogynes of Mycosphaerella tulipifera with attached spermatia, and described the migration of the spermatial nucleus into the ascogonium. Ames (1934) demonstrated the probable method of plasmogamy in Pleurage anserina, and Zickler (1937, 1953) has described the process, including migration of the spermatial nucleus into the ascogonium, in considerable detail for Bombardia lunata. Shoemaker (1955) has reported observing enucleate spermatia attached to trichogynes within six hours after spermatization in Cochlioboluls sativus.


INTRODUCTION: Dentistry is one of the most actively developing medical sciences. New concepts and approaches to dental care, comprehensive diagnosis of dental diseases are annually presented at scientific congresses and conferences of various levels. However, a number of traditional methods and approaches to comprehensive diagnosis of the dentoalveolar system remain relevant to this day. The presented article is devoted to the assessment of the relevance and practical application of the occlusiography technique in elderly patients with dentition defects of various extensions. AIM: Determination of occlusiography in elderly patients with various types of dentition defects, and its analysis. MATERIALS AND METHODS: This study is based on the determination and analysis of occlusion-graphy in elderly patients. A total of 150 patients were included in the study, who were divided into three groups. Group 1 — patients with terminal defects (unilateral and bilateral). Group 2 — patients with included defects (unilateral and bilateral). Group 3 — patients with combined defects (terminal and included). There were 50 patients in each group. Computer occlusiography and traditional occlusiography were performed. A proprietary method was used – a program of photographic morphometric analysis of control-diagnostic models. RESULTS: In group 1, high dependence of the results of the proprietary method of digital analysis of occlusiogram on the quality of the photo image was revealed. Due to the absence of a chewing group of teeth, the area of occlusal contact of incisors and canines was considered insignificant. The obtained results revealed a high chewing load on the frontal group of teeth with the absence of chewing teeth. Most of the occlusal contacts led to a complete loss of the wax layer on the occlusiogram. In the 2nd study group, with the presence of teeth limiting the defect, the tightness of occlusal contacts permitted to obtain a true occlusiogram. As a result, 75% of respondents had a small number of supracontacts, 93% of the subjects had supracontacts within the teeth limiting the defect of the dentition. With this, the preserved teeth helped obtain a high-quality imprint of the occlusal relief on an analog wax plate, which permitted to obtain the maximum similarity of the results of the proprietary method and of T-scan computer system (90%). In group 3, the wax template was additionally reinforced with occlusive wax in the area of the terminal defect of the dentition. In 85% of patients, supracontacts were located in the area of dentition defects, significant disorders of the position of the teeth limiting the terminal defect were noted. The reason for this may be vertical loads during chewing. In this group, the average deviation of the results of analog occlusiography from those of the digital one was 87.5%. CONCLUSIONS: It is recommended that occlusiography be used at the stage of diagnosis in all dental specialties.

Multistage acid fracture treatments are utilized in low-permeability carbonate reservoirs (permeability <10 md) to stimulate the formation by creating highly conductive fractures in the formation and bypassing near wellbore damage. The fracture is generated at high pressures that are required to break the rock open while using a viscous pad. The fracture is then kept open by adding gelled or emulsified acid to create uneven etches on the surface of the fracture.
 Pre-job acid fracturing treatment fluids' reaction and compatibility analysis in the laboratory are crucial as the operational success is highly dependent on its chemicals' reactions. The key problem with acid fracturing treatments is the difficulty in appraising the actual downhole reactions and performance of the treatment chemicals within the heterogeneous rock. This problem can be resolved when flow back fluids and the chemical ions are analyzed to understand the reactions that occurred down hole. Also, since acid fracture treatments require pumping large volume of fluids, flowing back the entire fluids becomes a challenge due to the low reservoir permeability and the associated reservoir rock capillary pressure effects.
 This paper will discuss the pre-fracture treatment evaluation based on laboratory experiments - core flood, rock dissolving capacity, and fluid compatibility in addition to comparing the expected chemical ion returns with the actual ions observed in the flow-back fluids.
 The results of this flow-back fluid analysis showed a recovery of 17% of the chemicals pumped during the treatment with a stabilized production rate of 3 MBOPD. Further water analysis indicated the presence of 25-30% formation water while the critical ions analyzed showed the effectiveness of the corrosion inhibitor package, acid system dissolving capacity, and crosslinker fluid recovery. It is expected that this paper will provide a learning process for optimizing future multistage acid fracture treatment in Saudi Arabia.


Christians in every era of Church history, in every culture, in every social setting, in every major liturgical tradition have adorned their gatherings with song. In a liturgical universe of extraordinary diversity, music is one of the handful of practices which has been and remains an almost universal feature of Christian worship. One author observes that "three acts, corporate prayer, public reading and corporate singing, form the basic building blocks of corporate worship in all of the traditions." 1 Prayer, scripture, and song—at first glance these seem obvious things for Christians to do when they gather together. It seems obvious that worshipping people should address God in prayer. It seems plain that they should attend to the words of God in Scripture. But the special contribution of song is less clear. "Sing joyfully to the Lord, you righteous," writes the psalmist, "it is fitting for the upright to praise him" (Ps 33:1). 2 But why should the people of God be urged to engage in this particular activity? Why not, "Dig ditches you saints of his, for the L ord is good!"? Why not, "Do beadwork, you righteous!"; or "Mime to him joyfully O Israel!"? Why, in other words, have so many, in so many cultures and traditions agreed with the psalm writer's assessment, and found music an especially fitting vehicle for praise?


Foreign direct investments (FDI) represent an essential part of the economic globalization process not only in emerging and developing countries, but also in the industrialized world. If multinational enterprises open up new markets through cross-border investments or establish international production networks as part of their aspiration to become more competitive, target countries also experience positive economic effects.

A study is made of the global routing of multiterminal nets. The authors propose a novel global router. Each step consists of finding a tree, called Steiner min-max tree, that is, a Steiner tree with the maximum-weight edge minimized (real vertices represent channels containing terminals of a net, Steiner vertices represent intermediate channels, and weights correspond to densities). An efficient algorithm is presented for obtaining a Steiner min-max tree, in a weighted graph. Experimental results on difficult examples, randomly generated data, master slice chips, and benchmark examples from the physical design workshop are very promising. (In all cases, previous results have been improved.).<<ETX>>


An access control system for a vehicle includes a rear closure and a system that controls movement of the rear closure between closed and open positions. The control system including a controller and a wireless communication module having a wireless interface configured for short range wireless communication. The controller receives an actuation signal requesting transition of the rear closure to an open position from a mobile communication device carried by a vehicle user. The controller then determines when the user enters authentication and actuation zones proximate the vehicle via communication between the wireless communication module and a short range wireless communication device carried by the user. One the user is within the actuation zone, the controller generates a rear closure control signal configured to cause the rear closure to move from the closed position to the open position.


Further analysis of the three-dimensional electron density map of yeast phenylalanine tRNA is presented. Attention is focused on the several types of unique hydrogen bonding that are found in the molecule and a number of sections of the electron density map are presented. These sections are compared with an electron density map of a dinucleoside phosphate. The bases in the helical stem regions are all involved in Watson-Crick hydrogen bonding interactions with the exception of the guanine-uracil base pair. Several additional tertiary hydrogen bonding interactions are described. The specificity in the structure and biological function of the nucleic acids is largely due to the highly specific hydrogen bonding that is found in these molecules. This is especially true for transfer RNA (tRNA). The nucleotide sequences of over seventy tRNAs have been determined, and all of them can be organized in the familiar cloverleaf diagram, which is composed of stems and loops, the stems containing regions in which sequences have complementary bases. Three years ago, the x-ray diffraction analysis of orthorhombic crystals of yeast phenylalanine tRNA at 4 A resolution showed that this tRNA molecule contained the anticipated right-handed, antiparallel double helical regions corresponding to the stems (1). The acceptor and T'C stems of the molecule were found to be approximately colinear and oriented along one arm of an L-shaped molecule, while the dihydrouridine (D) stem and anticodon stems were oriented nearly at right angles to it. These segments were found joined by a complex intertwining of the D loop and the TIC loop. At resolution the ribose-phosphate backbone could be traced, but it was not possible to resolve the additional tertiary hydrogen bonding. That information was revealed last year at 3 A resolution both for the orthorhombic (2) and the monoclinic (3) crystal forms of yeast phenylalanine tRNA. These two analyses were very similar, except that the electron density map of the monoclinic crystal was not sufficiently resolved to interpret the tertiary interactions that hold the D-loop and T'C loop together. We have continued our analysis of the orthorhombic crystals of yeast phenylalanine tRNA and presently have diffraction data to a resolution of 2.5 A. We have examined in considerable detail the electron density map that was constructed using the multiple isomorphous replacement (MIR) method. Here we document a large number of the hydrogen bonding interactions in yeast phenylalanine tRNA by presenting the MIR electron density maps at 3 A resolution together with the interpretations that we have placed on this map. In the course of this analysis we have confirmed the hydrogen bonding interactions that were described approximately a year ago (2) and have also discovered some additional interactions that further stabilize the three-dimensional structure of this

This article focuses on the debate over the role of "sustainable tourism" projects in rural spaces. While their apologists consider them effective tools to improve the quality of life of populations classified as "poor", its critics accuse them of being a mechanism from the dominant "world order" to impose its hegemony. Rather than fixing a favoring or rejecting position over this subject, the article's objective is to think over: (1) the local actor's position, (2) the scope of tourism initiatives financed by the international cooperation, and (3) the feasibility of reaching sustainability in the areas where they are implemented. In order to investigate it, a case study is created from the tourism component of a project denominated "Peru Biodiverso", which was executed in Peru's northeast (San Martin province). This research combines autoethnography and participant observation methodologies. It appertains to a wider study (doctoral thesis) that examines, through domestic and international policies related to tourism, globalization and "sustainable development" in rural spaces.


G‐protein‐coupled receptors (GPCRs) form a large protein family that plays an important role in many physiological and pathophysiological processes. Since the sequencing of the human genome has revealed several hundred new members of this receptor family, many new opportunities for developing novel therapeutics have emerged. The increasing knowledge of GPCRs (biological target space) and their ligands (chemical ligand space) enables novel drug design strategies to accelerate the finding and optimization of GPCR leads: The crystal structure of rhodopsin provides the first three‐dimensional GPCR information, which now supports homology modeling studies and structure‐based drug design approaches within the GPCR target family. On the other hand, the classical ligand‐based design approaches (for example, virtual screening, pharmacophore modeling, quantitative structure–activity relationship (QSAR)) are still powerful methods for lead finding and optimization. In addition, the cross‐target analysis of GPCR ligands has revealed more and more common structural motifs and three‐dimensional pharmacophores. Such GPCR privileged structural motifs have been successfully used by many pharmaceutical companies to design and synthesize combinatorial libraries, which are subsequently tested against novel GPCR targets for lead finding. In the near future structural biology and chemogenomics might allow the mapping of the ligand binding to the receptor. The linking of chemical and biological spaces will aid in generating lead‐finding libraries, which are tailor‐made for their respective receptor.


Li Hang is a famous prime minister during the period of Taizong and Zhenzong of Northern Song Dynasty.He reached the highest official position as prime minister in Zhenzong period.When in his position,he instituted much of official policy,not using the person who is crave for greatness and success,he persuaded the emperor not to be luxurious.He always said to his colleague :"The emperor is still younger,we should let him know that the difficulties of national affairs." So he was respected as great prime minister.


Different magnetic anisotropies and magnetization reversal mechanisms were identified in magnetic nano-objects of four-fold symmetry, using micromagnetic simulations. Nano-particles with lateral dimensions between 50 nm and 400 nm, simulated with typical properties of permalloy, iron and cobalt, were tested in dependence of the angular orientation with respect to the externally applied magnetic field. All nano-objects exhibited steps on the sides of the hysteresis loops, which can be correlated with stable intermediate states at remanence, for some angular regions. Coercive fields were found to show an irregular and unpredictable angular dependence in case of cobalt nano-particles, while this material depicted the largest number of steps in general. Comparing the angular dependence of the coercive fields with previous calculations, it was shown that usual descriptions of fourfold anisotropies are no longer valid in most of the nano-objects under examination.


This paper is aimed at introducing the social and legal status of the cook in the ancient Rome, especially in the period of the republic and empire. The author seeks in it for the answers to the following questions. What image is drawn in the light of the preserved extralegal and legal sources? Was cocus someone respected or despised? For what purposes did he associate with other cooks? Who cocus optimus was and who cocus mediocris was and how did it affect, if he was a slave at the same time, the responsibility of the seller? The image of a cook, which is drawn on grounds of preserved literary, epigraphic as well as legal sources is very diversified. Sometimes this profession was depreciated at Romans', some other time generated very positive reactions. This article consists of two parts. The first one basing on extralegal sources: literary or epigraphic, presents the sociological portrait of a cook. The second one analyses the selected legal aspects of this profession basing on, most of all, the preserved juridical sources especially CTh. 7,13,8 and D. 21,1,18,1.


Background and objective: Cardiopulmonary resuscitation should not be interrupted until the return of spontaneous circulation or the decision to withhold further treatment. There are no data on how consistent in‐hospital cardiopulmonary resuscitation is performed. Accordingly, the aim of the present study was to identify length and type of unnecessary interruptions in simulated cardiac arrests. Methods: The study was carried out in a patient simulator. A scenario of cardiac arrest due to ventricular fibrillation was used. Resuscitation teams consisted of three nurses, a resident and a staff physician. Using videotapes recorded during simulations, the activities of the teams were coded in 5‐s intervals. Unnecessary interruptions were defined as any interruptions in cardiac massage of 10 s or more that were not caused by defibrillation or endotracheal intubation. Results: Twelve teams were studied. The total time of possible cardiac massage was 414 ± 125 s. In each team at least one unnecessary interruption occurred (range 1‐5). Interruptions mounted up to 65 ± 40 s (range 20‐155) or 16 ± 10% (range 5‐41) of the total time of possible cardiac massage. Failure to swiftly resume cardiac massage after an unsuccessful defibrillation accounted for 14 of 39 episodes and for 44 ± 40% of the time of unnecessary interruptions. The debriefings revealed that participants had generally not noticed the unnecessary interruptions during the simulation. Conclusions: The present study identified a significant amount of unnecessary interruptions in cardiac massage. These interruptions were not noticed by the health‐care workers involved.


Electronic spectroscopic data are reported for Col, Corr, and Qsr | | rnsnsngclear tetra(neopentoxy) phthalocyaninate(2-) (Lt) and bridged binucleartri(neopentoxy)phthalocyaninate(2-) species in solution and film phases. Electrochemical data show that the [Cot t lt1 species cannot exist in a non-co-ordinating or weakly co-ordinating solvent containing hydroxide ion. Such solutions cause disproportionation of [Cor rL'] to a 1 : 1 mixture of [Cot Lt1 and [Cor rr Lr] * (axial ligands omitted). The detailed electrochemistry of this system is explored. The chemistry of these two oxidation states towards heat, light, acids, bases. carbonate and sulphite ion are briefly reported lor solution and film phases. The degree of intermolecular electronic coupling which occurs either through space, through the bridge, or directly in cofacial conformers is discussed in terms of the nature of the bridge of the binuclear species and oxidation state of the cobalt.


This paper presents a Real-time Maintenance Support System (MSS) to prognosticate breakdowns in production lines. The system is based on the sub-cycle time monitoring, mini-terms, and how the sub-cycle time variability can be used as a deterioration indicator that could describe the dynamic of the failure for the machine parts. A Real-time MSS has been installed at Ford factory located in Almussafes (Valencia), the so-called Mini-term 4.0. At present, three plants, Body 1,2 and 3 have hundreds of mini-terms sensed by the system. The connected production line elements are the welding guns, elevators, screwdriver and scissor tables. Mini-term 4.0 uses the well-known k-means algorithm to detect change points. The K-means constructs two groups and, when centroid values differ more than 7 % (orange alert), or 18 % (red alert), an e-mail is sent to maintenance team to schedule the maintenance task. Some examples of the different change point topologies detected are shown at the end of the paper.


The appearance and acts of the Ku-Klux ... cannot be disposed of by the opinions that they did not exist. Report of the Joint Select Committee to Inquire into the Condition of Affairs in the Late Insurrectionary States Mrs. [Harriet Beecher] Stowe thinks because she and a lady friend have been able to make the trip to Florida and return without being eaten up by the Ku-klux, that such clans do not exist in the South at all, and all that we read about them is bosh. Milwaukee Sentinel, June 10, 1871 ONE OF THE STRANGEST ASPECTS OF THE RECONSTRUCTION-ERA KU KLUX Klan was the inability of Americans to come to even the most basic consensus about its nature. (1) Despite the fact that both the United States government and major newspapers poured unprecedented resources into investigating it, and despite the extraordinary measures that the government took to suppress it, the most fundamental question about the Klan--whether it existed at all--never was entirely settled even in mainstream public discourse. (2) The heartiest and most consistent Klan denial came from those who had clear political motivations for it, like Democrats and, by 1872, Liberal Republicans backing Horace Greeley's presidential bid, but pre-1872 Republicans also expressed basic doubts about the information they received about the Klan. While Klansmen and their Democratic political allies deliberately spread doubt about Klan reports, they could not have succeeded as thoroughly as they did without the substantial, if intermittent, collaboration of their Republican opponents. Klan violence occurred at a time of profound transition in the mechanisms and institutions through which Americans received political information. In the decade following the war, Americans faced a substantial increase in the volume of published news. Moreover, news reached readers more quickly, with national news appearing in print generally within twenty-four hours. Editors continued to maintain partisan affiliations, but they began to make claims of neutrality in choosing which stories to publish from the vast tide available. These innovations radically changed the experience of reading the news. Individual readers had to determine how much confidence to put in newspaper editors' selection and presentation of news (was it really as neutral as some claimed?) and how to deal with the phenomenon of stories that continued to unfold rapidly as new information arrived from one edition to the next. At the same time, Americans collectively encountered an incipient national popular culture. The exchange system had long enabled some pieces of news to circulate nationally, but national trends of interest now emerged in a much more coordinated way. As the rapidity of communication created the possibility of feedback loops in which the reception of the story shaped the unfolding of the story itself, certain particularly interesting events and ideas began to take on a life of their own. In struggling to determine the nature of Klan violence, then, Americans were simultaneously struggling to evaluate the new ways in which news was circulating. Klan violence began in late 1867 and remained at a substantial level through late 1871 or early 1872. (3) The federal government, particularly from 1870 to 1872, devoted a great deal of its resources to determining the nature of the violence and then suppressing it with a use of force utterly unprecedented in peacetime. For roughly five years, from the spring of 1868 through the election of 1872, the Klan was central to national discourse. (4) Throughout this period, surprisingly, the debate over the Klan never effectively silenced the position that the Klan did not exist at all. Despite massive and productive public and private efforts to gather, circulate, and evaluate information about the Ku Klux Klan, and even though the federal government, in pouring unprecedented resources into countering it, certainly was behaving as though it were a real threat, the national debate over the Klan failed to move beyond the simple question of the Klan's existence. …


Summary Magnetic field inversions are non-unique but a realistic goal is to find a causative earth structure that is compatible with the geophysical data, the petrophysical constraints, and with geology. Invariably the inversion results are improved as the number and diversity of constraints are increased. In this paper we concentrate upon the inclusion of geologic structural information. Geologic structural modelling programs can import faults, boundaries, and strike and dips of geologic units and interpolate this sparse information in space. When provided with a 3D voxel mesh, they can compute a strike, dip, and plunge for each cell. Following previous work, structural geologic information is incorporated into the inversion as a weak constraint by encapsulating it into the model objective function. The model objective function is formed such that each prism has its own set of rotated vectors to enforce smoothness along the direction of the geology. User-controlled parameters specify the degree of smoothness throughout the 3D volume and thus allow additional geologic insight to be directly incorporated. In addition to structural geology, the inversion algorithm utilizes reference models and bound constraints that help us realize our goal of incorporating all available information. The efficacy of the inversion is demonstrated through a synthetic and a field example.

To assess the microcirculation parameters of diabetes sufferers we used the method of computerized capillaroscopy that allows one to visualize non-invasively and measure at a high accuracy the size of the perivascular zone, the blood flow velocity in the capillaries and the presence and duration of stasis. The sludge phenomenon and lipid inclusions also we studied non-invasively.


Traumatic brain injury (TBI) is known to cause short and long-term synaptic changes in the brain, possibly underlying downstream cognitive impairments. Neuronal levels of neurogranin, a calcium-sensitive calmodulin-binding protein essential for synaptic plasticity and postsynaptic signaling, are correlated with cognitive function. This study aims to understand the effect of TBI on neurogranin by characterizing changes in protein expression at various time points after injury. Adult, male rats were subjected to either controlled cortical impact (CCI) or control surgery. Expression of neurogranin and post-synaptic density 95 (PSD-95) were evaluated by western blot in the cortex and hippocampus at 24 hours, 1, 2 and 4 weeks post-injury. We hypothesized that CCI reduces neurogranin levels in the cortex and hippocampus and demonstrate different expression patterns from PSD-95. Neurogranin levels were reduced in the ipsilateral cortex and hippocampus up to two weeks after injury but recovered to sham levels by 4 weeks. The contralateral cortex and hippocampus were relatively resistant to changes in neurogranin expression post-injury. Qualitative immunohistochemical assessment corroborated the immunoblot findings. Particularly, the peri-contusional cortex and ipsilateral CA3 region showed marked reduction in immunoreactivity. PSD-95 demonstrated similar expression patterns to neurogranin in the cortex, however, in the hippocampus, protein expression was increased compared to sham at the 2 and 4 week timepoints. Our results indicate that CCI lowers neurogranin expression with temporal and regional specificity and this occurs independently of dendritic loss. Further understanding of the role of neurogranin in synaptic biology after TBI will elucidate pathological mechanisms contributing to cognitive dysfunction.


This paper proposes a new modulation method for an uncoded cognitive transmission (secondary user transmission) in presence of a Primary User (PU) for the AWGN channel. Interference of the PU is assumed to be known at the transmitter of Cognitive User (CU) non-causally. Based on this knowledge, for the design of the modulator and demodulator of the CU, a symbol by symbol approach is studied which can fulfill the coexistence conditions of the CU and the PU of the band. In this scheme, the modulator and demodulator of CU are designed jointly by solving an optimization problem to mitigate the interference of the PU and minimize the symbol error probability (Pe) in CU's communication link without increasing the symbol error probability (Pe) of the PU. The proposed method is a modulation approach in a single (complex-valued) dimension rather than a high dimensional coding scheme. Although this one-dimensional method is not capacity achieving, we show it still has a remarkable performance with low amount of complexity. An implementation algorithm for our modulation method is also presented and the performance of this method is evaluated by experimental results.


Chemical identity, the idea that every substance has at least one property that makes it unique and able to be differentiated from other substances, is core to the practice of chemistry. Such practice requires using properties to classify as well as to differentiate. Learning which substance properties are productive in chemical identity thinking is not easy, however, because many features of substances compete for a learner's attention. Assessments that utilize open-ended questions can reveal ways that students use chemical identity thinking to classify and differentiate substances. On the basis of our previously published hypothetical learning progression of chemical identity, we developed a set of four open-ended questionnaires, which can be used to uncover students' chemical identity thinking. In attending to literature on the development of qualitative research instruments, as well as design-based instructional materials development frameworks, a four-phase process of development was generated that i...

Objective To study the changes of expression levels of vascular endothelial growth factor(VEGF) and its receptors(FLT-1,FLK-1) mRNA in equal area of penumbra in diabetes rats with cerebral infarction(DMCI).Methods Middle cerebral artery occlusion(MACO) model was made in diabetes rats.The expression levels of VEGF and FLT-1,FLK-1 mRNA in equal area of penumbra were measured with situ hybridization in different times after MACO(1 h,3 h,6 h,12 h,24 h).The difference was compared between DMCI group and no diabetes cerebral infarction(NDMCI) group.Results The expression level of VEGF mRNA was lower in DMCI group than that of NDMCI group at every time point(P0.05 ~ 0.01).The expression level of FLK-1 mRNA was lower(P0.01) at 12 h after MACO in DMCI group than that in NDMCI group.Except for at 6 h,there was no significant difference between DMCI and NDMCI group in the expression level of FLT-1 mRNA.Conclusion The expression levels of VEGF and FLK-1 mRNA are reduction in DMCI early period,which may be partly responsible for poor prognosis in diabetes mellitus cerebral infarction.


In this paper the concept of individual action space is presented. The action space is defined as the area within the individual's farthest reach during a certain period of time. It is distinguished between actual and potential action space, the latter one being the area within the maximum distance attainable, subject to temporal and speed constraints. An action space model is presented. This model is related to previous accessibility models in geography, but it accounts for more complexity and wider differentation of choice and constraint conditions. Four variables are discerned: (1) the distance between the basic activity places (home, work place); (2) the travel speed; (3) the total time available; and (4) the travel time portion, which is the ratio between the travel time and the sum of travel time and sojourn (stay time). These variables determine together the individual's action space. The results show that the action space model is representative for types of actual action spaces. Some applications of this model are elaborated. (A) For the covering abstract of the conference see IRRD 876637.

Variable frequency controlled LCLL resonant converter when step-down, the narrow voltage gain range and wide switching frequency change range limit its step-down ability, but the step-up ability is excellent; While phase shift controlled LCLL resonant converter when step-down, because of the wide voltage gain Range and fixed switching frequency have a excellent step-down ability, but the step-up ability is poor. In order to realize that the bidirectional LCLL resonant converter has great buck-boost capability in a narrow switching frequency range, a hybrid control method of variable frequency boost and phase shift buck is proposed by integrating the respective control advantages of variable frequency and phase shift. Under this control strategy, the converter not only achieves the regulated output during bidirectional operation mode, but also has excellent buck-boost capability and soft switching characteristics. The working principle and characteristics of bidirectional LCLL resonant converter under hybrid control strategy are analyzed in detail in the article. And a 500W experimental prototype was designed to verify the performance of the bidirectional LCLL resonant converter under hybrid control. The experimental results verified the feasibility of the control strategy and the excellent buck-boost capability.


In the present paper we describe the results of a preliminary study of the paramagnetic resonance of spin-labeled crystals of horse oxyhemoglobin (HbO2). The central purpose of this work is to show that it is possible to obtain strong anisotropic paramagnetic resonance spectra from spin-labeled single crystals of proteins, and to show that structural information can be obtained from such spectra.


Few aspects of educational practice have created as much concern as classroom management and organization. They are among the most frequently requested topics for teachers in service; they head the list of concerns of school administrators and have recently attracted more attention from teacher educators and researchers. A teacher's ability to manage the classroom and to organize instruction are basic components of effective teaching. Many reviews of research on classroom management already exist (Brophy & Put-


The application of the correlation technique in the system frequency response analysis is presented in this paper. The frequency response analyzer is implemented in MATLAB ® Simulink environment and has been tested under different working conditions. Two examples are selected to stress the good features of the analyzer. An electromechanical system has served to show that the remarkable frequency analysis results can be obtained even under conditions of significant additive effects of signal noise on the system output. In another example, by using the developed analyzer the frequency characteristics of a system with non-rational transfer function are investigated.

University stakeholders recognize the importance of exposing all students to academic advising as a means to enhance their engagement with the institution. Living-learning communities are of particular promise. In this study, conducted at a midwestern land grant university in the 2004–05 academic year, advisees in living-learning communities reported significantly higher engagement in their educational experiences than advisees with access only to a central advising office, and the differences in levels of engagement with advisors were significant as other predictors of engagement were taken into account.

account of recent political events. I am not always convinced that such responses to recent events are as likely or as important as is claimed. A subjective criterion like 'monotonia espositiva' (p. 16) is not really proof that Peace was so changed. However, if Knights was largely composed after Sphacteria, the question of what playwrights showed to the Archon is sharpened (but I find it most unlikely that only the 'canti corali' were shown [p. 11]). In general, M. is more confident about drawing historical facts from the plays than some would be: does Frogs 89-91 necessarily show an increase in the number of tragic poets towards the end of the century (p. 9), and is supporting a birth-date of 450 by reference to the likely age for the onset of 'una precoce calvizie' not perhaps a little bold? A third chapter then treats with commendable concision language, literary quotation and stage-craft. The manner is largely traditional: modern theories about drama are mentioned but not much used. There are useful pages on the question of how many of the allusions, quotations etc. may have been picked up by the audience (pp. 141-59): although there is an (acknowledged) tendency to schematize the audience into a majority of' ingenui', with a minority' elite culturale' or 'un pubblico nel pubblico' (p. 159), the question is well-handled, and especially of note is the importance given to rivalry with other comedians. The book ends with an account of the ' dibattito critico' on A., concentrating mainly on the last decades, and a select bibliography (upto-date, but there are some gaps: e.g. VaioG/tBS'1971 on Wasps, Martin Cl. Phil. \9%1 onLys., Cornford's Origins: religious aspects are largely ignored). A useful introduction, therefore, but I would have liked to see more on the question of interpreting the plays. M. gives brief plot-summaries and discusses many individual passages, but one misses a more thorough discussion of the meanings of the plays as individual dramas. Despite the breadth of treatment, the basically historical approach risks ultimately providing a somewhat monochrome picture.

Prenatal ultrasound has its pros and cons, the pros being an effective means to assess gestational age and to identify fetal anomalies, whereas the cons are the potential risks associated with exposure to ultrasound, especially with increasing exposure times. Autism spectrum disorder (ASD) is caused by several factors, including infections and toxins. This study aimed to compare the ASD frequency in two cohorts of children, namely, those who were exposed to ultrasound at 12 weeks of gestation and those who were exposed to ultrasound at 18 weeks of gestation. The study population consisted of 39,000 Swedish pregnant women who were randomized to ultrasound examination at either 12 to 14 weeks of gestation or 15 to 20 weeks of gestation in the NUPP (NackUPPklarning, meaning nuchal translucency) trial. The duration of the scan was the same for both groups (30 minutes). The current study cohort comprised children born to women who had participated in the NUPP trial and whose condition had been diagnosed as ASD. The outcome was the rate of ASD identified among the children. A total of 14,726 children were born to women in the 12 weeks' (early) gestation group and 14,596 children were born to women in the 18 weeks' (late) gestation group between 1999 and 2003. About 1.2% (n = 181) children in the early group and 1.2% (n = 176) children in the late group were identified to have ASD. The difference in sex ratios between children with ASD exposed to early and late ultrasound was insignificant (odds ratio, 1.41; 95% confidence interval [CI], 0.86–2.32). The mean age of the mother at delivery was 31 years in the early group and 30 years in the late group. The study concluded that ASD rates in children were similar irrespective of duration of exposure ofmothers to ultrasound at 12weeks' or 18weeks' gestation. Hence, more research is required to assess potential adverse effects of ultrasound exposure at various times during pregnancy.


Lung cancer is the leading cause of cancer-related death worldwide. Patients living with lung cancer often experience severe physical and psychological symptoms including dyspnea, fatigue, anxiety, decreased exercise tolerance, muscle weakness and compromised health-related quality of life as a direct consequence of the disease or as an indirect consequence of the cancer therapy itself. As both screening and treatment modalities improve, the number of people living with a diagnosis of lung cancer is increasing. Consequently, management of cancer-related symptoms as well as improvement of overall quality of life and functional status become critical issues in lung cancer patients. Thus, during the last decade, a wide range of exercise prescriptions and training modalities has been proposed and an emerging literature has addressed the effects of exercise-based rehabilitation programs along the continuum of the disease. The aim of this review is to address the latest literature regarding the feasibility and effectiveness of exercise-based rehabilitation for patients with lung cancer receiving treatments (perioperative, during chemotherapy/radiation therapy or following them) or for patients with advanced diseases. We also address how the use of new technologies or training modalities such as home-based telerehabilitation or neuromuscular electrical stimulation appears to be a promising approach to improve accessibility and participation in exercisebased rehabilitation programs. Evidence from our review suggests that pre and post-operative exercise-based rehabilitation appear to be safe and effective approaches to use with patients with lung cancer and for those with advanced disease receiving chemotherapy/radiation therapy. Larger randomized controlled trials are needed to confirm the efficacy of exercise interventions in this population.


The regeneration process of a sulfided dolomite with steam and carbon dioxide was analyzed in a thermogravimetric system at temperatures between 475 and 650 °C. Different gas concentrations from 5 to 40% and different H2O/CO2 ratios were used to isolate the effect of the different gases on the regeneration process. The morphological changes of the sorbent during regeneration and cyclic sulfidation/regeneration reactions were followed by SEM-EDX analysis, which indicated a grain structure inside the particle. The changing grain size model with a variable diffusivity in the CaCO3 product layer was used to predict the experimental data, and to obtain the kinetic parameters of the regeneration reaction. The sintering of the CaCO3 has showed to be responsible of the changes in the solid diffusivity along the time, the H2O being the more important sintering agent on the process. Finally, the dolomite was subject to the calcination/sulfidation/regeneration process during 20 cycles and no activity loss was detect...


In medicine, the term "compliance" is associated with medical practice and guidance, especially in relation to chronic diseases. Its definition has evolved with the development of modern medicine. In the last decade, the relationship between patient and doctor has changed significantly. The increasing importance of therapeutic success is attributed to the personalization of medicine and the consideration of patients' perspectives and preferences. The purpose of this manuscript is to find a modern definition of the term compliance in relation to diabetes and to determine what elements of personalized medicine can be incorporated into patient care to improve overall clinical success. In this article, the authors discuss the topics of compliance and personalized medicine in diabetes care taking into account both available medical publications as well as many years of the authors' own clinical experience.


Two surgical models of intestinal transplantation in the rat are described. One is the implantation of fetal and newborn intestine as free grafts into the omentum of adult recipients, the other the adult intestine transplantation as an accessory graft using vascular anastomoses. A hundred and sixteen small‐bowel transplantations were done; 36 of which were fetal intestine (group I), 40 of newborn intestine (group II), and 40 of adult intestine (group III). In the fetal and newborn intestinal transplantation, we emphasize the practices that allowed us to avoid ischemic and traumatic injury to the graft. In the adult intestine transplantation with vascular anastomoses, we heighten the modifications in the surgical technique that made the operation easier and the strategies used to prevent hypothermia and hypovolemic shock.

To fully realize the potentialities of soybean, the great importance has the main tillage and the use of highly efficient means of protection of plants, since they have the most significant effect on the optimization of the photosynthetic activity of crops. The purpose of our research was to study the different intensity of the main ways of soil cultivation and the use of herbicides Pivot and Harmony Classic on indicators of photosynthesis, such as the formation of a sheet surface, the accumulation of dry substance in bodies of plants, crop yields. It is established that the methods of the main soil cultivation influence on parameters of photosynthetic activity of crops. In the cultivation of soybean using moldboard plowing the size of leaf surface reaches 39,5...53,9 thousand m2/ha, the accumulation of dry matter 7791...8096 kg/ha. Activation of photosynthesis at ploughing contributes to significant increase of soybean yields. Application of herbicides Pivot and Harmony Classic increases the leaf surface, the accumulation of dry matter, however, the most significant effect on the yield of seeds is observed on the variant with zero tillage (20,8...23,3%). Notable differences in the effect on indicators of photosynthesis between the studied herbicides are not received.


Purpose : The purpose of this study was to determine the effects of upper extremity volume, pain, and range of motion after participation in thera-band exercises according to the hand grip type in patients with breast cancer with upper extremity edema. We also aimed to determine the most efficient type of grip.
Methods : The subjects were 10 female patients diagnosed with stage 2 breast cancer who had stage 2 lymphedema. Randomly, 5 patients each were allocated to the experimental and control groups. For six weeks, the patients in both the experimental and control groups exercised daily. In both groups, manual lymph drainage was applied for 1 hour. Afterward, patients in the experimental group placed their hands in the thera-band ring and exercised with their fingers outstretched. Patients in the control group exercised while holding the thera-band ring with a finger. Both the experimental group and the control group underwent measurements of the circumference of the upper extremity, pain, and range of motion of the shoulder joint at weeks 1, 2, 4, and 6 before and after exercise.
Results : The upper arm circumference decreased by more in the experimental group in all weeks than before than that in the control group, and there was a statistically significant difference at 6 weeks. Compared with the difference between pre-exercise and 6 weeks post-exercise, the change in pain significantly decreased in the experimental group and showed a statistically significant difference. The shoulder range of motion increased in extension, external rotation, and internal rotation compared with that in the control group, and there was a statistically significant difference. Although the operating range increased in flexion and abduction, there were no statistically significant differences.
Conclusion : In this study, we found that thera-band exercises with an open-hand grip are more efficient than thera-band exercises with a closed-hand grip in edema reduction, pain, and range of motion. In addition, it was found that it was more effective to continue the thera-band exercises with open-hand grip extended for at least 6 weeks rather than for a short time.


Summary. Monoclonal antibodies for the β‐globin chain of human HbA (UCHβ) and the γ‐globin chain of human HbF (UCHβ) have been made. UCHβ indirectly labelled with rhodamine‐labelled goat anti‐mouse lg and directly fluores‐ceinated UCHy have been used, via double labelling immuno‐fluorescence microscopy, to assay for the presence ofβ‐chains in fetal erythrocytes obtained at fetoscopy from fetuses at risk for β‐thalassaemia major. The results from 111 cases demonstrate that β‐chain synthesis of as low as 1.8% can be detected in fetal erythrocytes. The immunochemical labelling can be rendered more sensitive by the use of biotinylated UCHβ and avidin‐FITC conjugates. This method is rapid and can be used for a sample that is highly contaminated with maternal erythrocytes.


This paper investigates the use of a shifting algorithm for improving the results of smoothed particle hydrodynamics (SPH) multi-phase simulations by preventing the creation of unnatural voids. Particle shifting occurs according to a Fickianbased algorithm so particles maintain a nearly uniform distribution. A modification of the shifting algorithm is necessary in the air phase to avoid unphysical void formation. In conjunction with the use of graphics processing units (GPUs) for the acceleration of the simulation, the new shifting algorithm allows the simulation of complex multi-phase flows such as a wet dam break and a sloshing tank. Finally, the shifting algorithm is extended to 3-D and validated with the SPHERIC benchmark test case of dam break impacting an obstacle.


In 2019 a strikingly colored species of Liposcelis (Insecta: Psocoptera: Liposcelididae), unknown from the Palaearctic region, was collected by A. Ostrovsky in an ant's nest near Gomel city (Belarus). It is here described as Liposcelis aleksandrowiczi n. sp., a bisexual sister species to the parthenogenetic (thelytokous) New World Liposcelis ornata Mockford, 1978. The new species can be distinguished from L. ornata by slight differences in body coloration, and by some details of pronotal chaetotaxy and head pilosity.


OBJECTIVE: To report a case of aplastic anemia that developed during ticlopidine treatment. CASE SUMMARY: An 84-year-old woman was started on ticlopidine for secondary stroke prevention. Within six weeks of initiating ticlopidine therapy she developed aplastic anemia. She was hospitalized and received empiric antibiotics, antifungal agents, blood transfusions, platelets, and granulocyte colony-stimulating factor. The patient died on day 76 after beginning ticlopidine. DISCUSSION: Hematologic effects such as neutropenia, thrombocytopenia, agranulocytosis, thrombotic thrombocytopenic purpura, and pancytopenia have been described with the use of ticlopidine. Previous case reports have associated ticlopidine with the development of aplastic anemia. CONCLUSIONS: Ticlopidine can produce fatal hematologic adverse effects, and its use should be reserved as second-line therapy.


The antiulcer activity of a hydro-ethanolic extract prepared from the stems of Kielmeyera coriacea Mart. (Guttiferae) was evaluated in rats employing the ethanol-acid, acute stress and Indomethacin models to induce experimental gastric ulcers. Treatment with K coriacea hydro-ethanolic extract provided significant antiulcer protection in the ethanol-acid and Indomethacin models, but not in the acute stress model. These results suggested that the K coriacea hydro-ethanolic extract increased resistance to necrotizing agents, providing a direct, protective effect on the gastric mucosa.


The time delay for light transmission in a coupled microring waveguide structure is calculated from the phase shift of the transmission coefficient obtained by Padé approximation with Baker's algorithm from FDTD Output. The results show that the Padé approximation is a powerful tool for saving time in FDTD simulation.


This paper puts forward a new method of auto-sampling of the surface flaw signal data of axis-like parts by using eddy current sensor and scan dividing disk, discusses on the ranges of fixed value when the method is used in the sampling of degree-division by equal phase, and validates the auto-sampling system of degree-division by equal phase.


Effects of heating temperature and 0. 37% Nb microalloying on complete decarburized depth and microstructure of spring steel60Si2CrVAT was investigated by isothermal heating experiments in a box-type resistance furnace. The results show that complete decarburization occurs between 675 ℃ and 875 ℃ when the holding time is 90 min. Decarburization sensitivity is high in 800-875 ℃,and the maximum depth is found at 850 ℃. The ferrite grains in the complete decarburized layer are thick columniform. After the addition of 0. 037Nb% niobium,no obvious effect on complete decarburized depth is found,but the significant effect on microstructure of the complete decarburized layer is observed.


Abstract We suggest a method of realisation of inversion over the standard bases of finite fields GF(pn ) by means of circuits over GF(p) of complexity and depth , where ɛ > 0, and w < 1.667 is the exponent of multiplication of × and × n matrices. Inversion over Gaussian normal bases is realised by a circuit of complexity and depth , where b, c are constants.


In Mobile ad hoc network (MANET) all nodes are battery operated, as battery power or batter energy is limited resource therefore it requires special attention to minimize energy consumption in MANET. For MANETs, optimization of energy consumption has greater impact as it directly corresponds to lifetime of networks. In WSN, sensor nodes have a limited storage capacity and limited transmission range. Maintenance of routes in wireless sensor network is the responsibility of the routing protocols. In this paper we discuss about the various routing protocols and study their behavior in MANET.


To achieve a missile capability that is commensurate with the long-range, high data-rate, targetdetection characteristics of the AN/ SPY-IA radar, an evolutionary upgrade of the existing STANDARD Missile-l was authorized. Designated STANDARD Missile-2, it adds a command midcourse flight phase, thereby providing the AEGIS Combat System with increased intercept range and higher firepower . STANDARD Missile-2 with inertial midcourse guidance also provides upgraded TERRIER and TARTAR Combat Systems with a corresponding increase in capability. Terminal guidance accuracy has also been improved by incorporating a new homing receiver common to all STANDARD Missile-2 variants.

In order to transfer a series of data files between two computers, each computer is provided with a file transfer mechanism. The file transfer mechanism is responsible for the overall control of the transfer of the series of files. Each file transfer mechanism controls the transfer of a series of files in accordance with a protocol. In this protocol, the computer receiving data files (the initiator) sends a poll request message to the computer transmitting the data files (the responder). In response, the responder sends a reply message to the initiator containing a list of files which are available for transfer. From this list, the initiator selects the files which it wishes to receive and then copies each file in turn. It then sends an acknowledge to the responder.

The brightness is adequate for black and white or color photography and yet the increased heat load is nil.


Globalization Era has pushed the communication around the world to be more intensive. The communication that has been provided by technology can even be used real time. Globalization also pushed the cooperation of universities or institution between countries, Communication is needed to establish cooperation, and teleconference is the best method of communication to establish this cooperation. Nginx and RTMP is used to develop this broadcast server, the server can be used for live streaming both publicly and privately, via self-owned hardware and network, so the usage of existing platform can be negated.  Users are able to use the server for teleconference and other real-time communication activities. Server can also archive the live streaming session, and the file from archive can be played on demand. The server can also become a relay to transmit a stream that its currently receiving to another platform or other server. After a series of test, server is able to use the features than had been worked on, and can be used as self-hosted server for live streaming, especially teleconference.


Linum usitatissimum L. (Flaxseed) otherwise called linseed and is developed significantly for seeds all through the world for therapeutic and commercial purposes. It is a yearly herb found in the Linaceae family. The plant of flax contains light blue blooms and capsules of fruits loaded up with little, dark-colored seeds. Flaxseed is utilized all through the world for their fiber content and oil. Flaxseed oil is the most extravagant wellspring of the omega-3 unsaturated fat Linolenic acid with a run of the mill levels of fifty-five percent in the oil. Flaxseed contains numerous bioactive mixes like cyclic peptides, lignans, proteins, cynogenic glycosides and dissolvable and insoluble strands. From the antiquated time, flaxseed has been utilized as an emollient, topical demulcent, and diuretic, especially for animals. Flaxseed cakes have been utilized as cows feed. This plant gives pharmacological uses to human body in serious sicknesses, as in bipolar issue, git obstruction, malignant growth, dyslipidemia, diabetes, platelet aggregation, hypertension, depression, lupus nephritis, Attention deficit hyperactivity disorder, gout, menopausal side effects. The advantages of utilization of entire flaxseed parts, for example, whole oil, mucilage, and protein demonstrate that whole arrangement of constituents present is required to conform to pharmacological action with explicit compound.


This paper discusses two well-known phonetic-phonological phenomena of Japanese, vowel devoicing and mora-timed rhythm. Regarding vowel devoicing as a process of vowels getting consonantal, it may change the mora-templated syllable structures of Japanese, resulting in the deviation from mora-timed rhythm. To investigate spontaneous Japanese with comparison to other languages, the label data of OGI_TS was analyzed. First, it seemed that vowel devoicing occurs more frequently in spontaneous Japanese than in controlled speech. In spontaneous speech, vowel devoicing frequently occurs even in the environments non-typical of vowel devoicing. Next, rhythm analysis showed that it is close to syllable-timed rhythm. These results suggest that vowel devoicing caused spontaneous Japanese deviates from mora-timed rhythm moving to syllable-timed.


The complexity of the glass-to-rubber transition of polymer film is briefly discussed. It is shown that the friction, adhesion, modulus and topography of the polymer film can be observed and measured readily by scanning force microscopy (SFM). The results indicate that SFM is a powerful tool in this area.


Current infra-red focal point arrays are limited by their inability to calibrate out component variations. Nonuniformity correction (NUC) techniques have been developed and implemented in off-board digital hardware to perform the necessary calibration for most IR sensing applications. There are two possible types of NUC that can be considered for focal-plane integration: (1) Two-point correction using calibrated images on startup and (2) Scene- based techniques that continually recalibrate the sensor for parameter drifts. The problems with the two-point methods have been well-documented in the literature (parameter drift, expense, etc.) We address the two major problems of scene-based techniques: (1) a more difficult hardware implementation and (2) ghosting artifacts in the corrected images. We have previously addressed the implementation problems by developing and demonstrating special purpose analog hardware as well as an efficient digital algorithm that incorporates the constant statistics model. The ghosting artifact occurs in all scene-based techniques when an object that does not move enough tends to `burn in' and can remain visible for thousands of images after the object has left the field of view. We have improved our model to eliminate much of the ghosting artifact that plagues all scene-based NUC algorithms. By modifying the correction update during ghosting situations, we are able to significantly remove the ghosting artifact and improve the overall accuracy of the correction procedure. We demonstrate these results on real and synthetic image sequences.


Since the 80s of the 20th century,bureaucracy was unprecedented criticism in the West,mainly from the five critically on the Bureaucracy: inefficient theory,defect theory,obsolete theory of threat and penetration.Summed the criticism and reflection,not only help us to re-examine the Bureaucracy System,but also can give us a clear research direction.


At the centre of this book is an analysis of what Rabelais called 'la plus grande villanie du monde'—'the world's greatest villainy' (Pantagruel chs. 21–2). In this episode, Panurge enacts a vengeful trick on a Haughty Lady who spurned his advances. Chapter 8 evaluates divergent allegorical readings of the trick in relation to the episode's farcical, scatological, and legal overtones. Since there is no judicial redress, Rabelais leaves us with an unfixed vilain et énorme cas of sorts: a situation that is morally, criminally, and aesthetically vilain; and énorme in an ever-expanding, spatial sense. Across the chapter, Panurge's expansive villainy (panourgia) is explored in relation to his ageist–sexist tendencies, and in relation to his taste for facetious litigation (causes grasses) in the first half of Pantagruel. To these may be added his remonstrating against the scandalous 'heretic' Raminograbis and his cowardly, diabolical ravings (Tiers Livre chs. 21–3).


The development of a prototype knowledge‐based expert system (KBES) for selecting appropriate traffic control strategies and management techniques around highway work zones is described. The knowledge base of this KBES is derived from a literature survey on existing techniques and approaches for handling traffic around highway work zones and from interviews with selected experts in charge of the planning and design of traffic control strategies for work zones in Virginia. The developmental process includes steps in formulating the problem and developing an expert system: identification, conceptualization, implementation, and testing. The resulting EXSYS prototype system, TRANZ, is described. TRANZ knowledge base consists of 141 rules. A decision tree is developed to provide an aid to resolve erroneous recommendations by the system. This model shows the range of control options and associated condition variables that intersect to produce control requirements. This EXSYS prototype system is the initial stag...


Rachel Maxwell-Hyslop (Fig. 1) was one of the first three students to be admitted to the Institute, in 1934, even before it had a building, and she later joined the staff as a member of the Department of Western Asiatic Archaeology. She recalls her early teachers and her later work with Max Mallowan and other colleagues during the formative years of the Institute.


Dendritic carbosilanes based on phenylethynylmethylsilanes (PhCC)4−nMenSi (n = 0–2) as cores were synthesized. The building blocks of the dendrimers consist of double bonds (PhCCHMeSi) in the inner shell and triple bonds [(PhCC)2MeSi] on the outmost periphery. The synthetic methods used the iterative alkynylation and hydrosilation cycle, which was composed of lithium phenylacethylide and dichloromethylsilane. The limiting generation of the dendrimer for the four branching type (PhCC)4Si at a core molecule has 32 phenylethynyl groups on the third generation, 48 for the three branching type (PhCC)3MeSi on the fourth generation, and 64 for the two branching type (PhCC)2Me2Si on the fifth generation. The dendrimers were characterized by the use of NMR, Maldi mass, SEC, DSC, UV as well as elemental analysis. © 2000 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 38: 2749–2759, 2000
