Ayurveda is science of life. Ayurveda not only focuses on curing of diseased individual but also gives importance to maintenance of health of healthy person.Ayurveda is basically divided in Ashtangas (Eight Appendages). All these Ashtangas represents specific field of expertise in Ayurveda context. Out of these eight, Kaumarbhritya is field related to care of children. Kashyap Samhita is considered as the masterpiece of texts related to Kaumarbhritya. Kashyap Samhita was written by Acharya Kashyap, in the same time during which Charak Samhita was written.Rasashastra is study of use of metallic and mineral compounds for preparation of mineral & herbomineral formulations. References of Rasashastra being a specialty are found in classical texts since 800 A.D. But, there are some references scattered in various Samhitas regarding use of Rasashastra Dravyas. Kashyap Samhita being one of the old Samhitas is also not an exception to this. In this review article, an attempt was made regarding unveiling the references of Rasashastra Dravya in Kashyap Samhita and it was noted that a lot of references of Rasashastra Dravya are there in Kashyap Samhita in form of either internal administration or external application or for giving Drushtant (example).Â


Several factors might account for a relationship between thromboembolic disease and cardiovascular disease. First, common precipitating factors may account for both venous and arterial thromboembolic disease. For example, certain environmental "stresses" such as cold temperature or exposure to pollutants might precipitate both coronary thrombosis and venous thromboembolic disease. Also, similar metabolic changes might be related to the onset of disease in both the arterial and venous systems especially in relation to clotting and fibrinolysis. Second, etiologic variables may be similar in both diseases; thus, obesity may be related to both cardiovascular disease and thromboembolic venous dis-


The concentrically braced frame (CBF) suffered from low dissipating energy capacity although it pertains to a high lateral elastic stiffness and ultimate strength. To overcome the shortcoming, in this paper, an innovative damper made of two butterfly‐shaped plates installed at the end of the diagonal member of the CBF was considered experimentally and numerically. Also, the required equations were presented to design the system. In an experimental study, the damper showed stable hysteresis loops without any degradation in stiffness and strength up to a rotation of 12% (0.12 rad). This rotation capacity is 50% greater than the AISC limitation. Also, the numerical study indicated that by increasing the angle of main plates, the structural parameters are improved as ultimate strength (Fu), 47% to 90%; stiffness (K), 64% to 97%; energy absorption (E), 23% to 11%; and overstrength (Ω), 59% to 96%. By reduction of the damper's height, the parameters Fu, K, E, and Ω are increased by 47% to 76%, 23% to 64%, 49% to 93%, and 23% to 27%, respectively. Moreover, although the geometry of the damper affected the elastic stiffness, the stiffness in the nonlinear zone was independent of the geometry of the damper. Correspondingly, the slenderness limitations were suggested as 15 for height to thickness ratio and 22 for wide to thickness ratio.

THE investigation of unexplained or untoward deaths is a matter of concern to all civilized states. Three systems are in common use. The continental system is current in many European countries. Here the investigation of such deaths is a responsibility of the police, to whom such cases are reportable and who undertake all phases of the preliminary investigation, reporting to the public prosecutor those cases requiring further investigation on his part. The medical examiner system, current in various parts of the United States, places a medical examiner, who is a trained pathologist, in charge of these investigations, and he reports to the district attorney cases which in his judgment call for further legal action. The coroner system, current in England and throughout the British Commonwealth, places a coroner in charge of the investigation which may culminate in a coroner's report or in the verdict of a coroner's jury, which may or may not indicate further action on the part of the public prosecutor, the crown attorney.Inthe investigation of untoward deaths in England, coroners have played a prominent part since before the Norman conquest. The unexplained death of a subject was a matter of great concern to the king in those early days, particularly to the Norman kings, when so many Normans were being waylaid and murdered by Anglo-Saxons.


Let X 1 ,…,X n be any n random variables (rv's) and let X 1:n ≤ … ≤ X n:n denote the same variables arranged in nondecreasing order. Then X r:n is called the rth order statistic, r = 1,…,n. When one of the X's is dropped at random, there results a simple relation between the order statistics in the original and the reduced samples. This " dropping " argument will be shown to provide a unified approach to establishing recurrence relations between moments of order statistics, whatever the dependence structure of the observations. Also useful in studying recurrence relations is the classical theorem on the probability of occurrence of r events out of n. It will also be shown that a simple general method of obtaining universal bounds for linear functions of order statistics in terms of the sample standard deviation can be based on Cauchy's inequality coupled with convexity arguments.


In this paper, we propose a theory by extending the Babinet principle to periodic subwavelength anisotropic metallic crevice elements <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> in the interface of different substrates. The significance of the proposed theory is that it can readily be used to transfer the solution of <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> to that of its complementary metallic elements <inline-formula> <tex-math notation="LaTeX">$A^{c}$ </tex-math></inline-formula>. First, the Babinet principle is established for <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> and its complementary magnetic elements <inline-formula> <tex-math notation="LaTeX">$A^{m}$ </tex-math></inline-formula> according to the uniqueness theorem of boundary conditions, and <inline-formula> <tex-math notation="LaTeX">$A^{m}$ </tex-math></inline-formula> is replaced with the corresponding metallic elements <inline-formula> <tex-math notation="LaTeX">$A^{c}$ </tex-math></inline-formula> based on the dual principle. Then, the waves associated with <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$A^{c}$ </tex-math></inline-formula> are considered as plane waves since their period is smaller than the operation wavelength. Thereby, the Babinet principle is reexpressed as mathematical relations between tangential transmission matrices of <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$A^{c}$ </tex-math></inline-formula>. Next, the tangential transmission matrices of <inline-formula> <tex-math notation="LaTeX">$A^{c}$ </tex-math></inline-formula> are solved using the corresponding circuit model, where the effective relative permeability is introduced to describe the inductive influence of the dual substrate. Finally, the tangential transmission matrices of <inline-formula> <tex-math notation="LaTeX">$A^{e}$ </tex-math></inline-formula> are derived, and the proposed theory is verified by two examples. The theoretical results agree well with the simulated ones at normal incidence (for various substrates) and over a large range of incidence angles (up to 75° and 60° for the two examples, respectively). The measured results support the simulation and the proposed theory.


Abstract The current Middle States Commission on Higher Education accreditation guidelines suggest an enhanced role for faculty members in information literacy instruction. A campus-wide information literacy committee can play a key role in accomplishing this. Such a committee at the University at Albany, SUNY, has been critical in addressing this recommendation, and in advancing a general education information literacy requirement. The committee serves as a source of information and as an organizer of workshops for faculty members who would like to tailor their courses to fit the general education information literacy requirement. It also serves as a syllabus review body and advocates for collaboration with librarians in this distributed model of information literacy instruction.

This paper explores the ways in which practitioners in children and family social work teams make sense of information in their work. By examining observations and recordings from an ethnographic study, the paper focuses on how informal discussions within the office space inform and affect social workers' analysis (or sense-making). Three elements of sense-making activity are illustrated with vignettes and extracts from field notes: methodical doubt, proximity/reflexivity and security. These three distinct features of practice are then discussed and the significance of the findings considered in relation to contemporary practice. The paper highlights the importance of informal interaction and discussion in the social work office as part of the process of social workers' sense-making. It indicates that feelings of trust and security may be linked to intellectual curiosity and an ability to work with uncertainty in sense-making. Ethnography can provide a means of illuminating this complex and inaccessible element of practice and the findings add to the body of knowledge. Practitioners and organisations may wish to reflect on the findings and consider how they contribute to, and are affected by, such cultures and practices. Copyright © 2017 John Wiley & Sons, Ltd.

We introduce a new semirelativistic quantum operator for the length of the worldline a particle traces out as it moves. In this article the operator is constructed in a heuristic way and some of its elementary properties are explored. The operator ends up depending in a very complicated way on the potential of the system it is to act on so as a proof of concept we use it to analyze the expected distance traveled by a free Gaussian wave packet with some initial momentum. It is shown in this case that the distance such a particle travels becomes light-like as its mass vanishes and agrees with the classical result for macroscopic masses. This preliminary result has minor implications for the Weak Equivalence Principle (WEP) in quantum mechanics. In particular it shows that the logical relationship between two formulations of the WEP in classical mechanics extends to quantum mechanics. That our result is qualitatively consistent with the work of others emboldens us to start the task of evaluating the new operator in nonzero potentials. However, we readily acknowledge that the looseness in the definition of our operator means that all of our so-called results are highly speculative. Plans for future work with the new operator are discussed in the last section.


As the world's largest beauty group, the future development trend of L'Oréal Group will always affect many industries around the world. However, while facing the tremendous pressure of competition in the same industry, the pressure of the new crown epidemic has suddenly come, and the L'Oréal Group is facing an unprecedented crisis. After studying the 2020 strategy released by the L'Oréal Group, in order to study and analyze the future development strategy of the L'Oréal Group, and provide a theoretical basis for the development of the company, the author based on swot analysis and AHP analytic hierarchy process, through qualitative analysis and quantitative analysis, constructed Its AHP hierarchical structure model and weighted histogram, after studying the data, came to the conclusion that L'Oréal Group should adopt the WT strategy in the future, and put forward 6 related suggestions.


Public opinion has two sides: rationality and irrationality. Any emphasis of one side will lead to an extremity. The rational attitude towards public opinion should be a full consideration of both the two sides; in another word, trying both to ensure the freedom of public opinions and to prevent from pleasing and flattering the public. To be specified, we would rather guide than control the public opinion, thereby to change them from irrationality and meanwhile stop flattering the public and stop the mass violence.


The comprehensive industrial safety standards and codes that exist today have evolved from lessons learned through past experience, research results, and improvements in technological capabilities. The current requirements for fire safety features of commercial nuclear power stations operated in the US are a notable example of this practice. Although fire protection has always been an important design requirement, from the aftermath of a serious fire that occurred in 1975 at the Browns Ferry plant, it was learned that the life safety and property protection concerns of the major fire insurance underwriters may not sufficiently encompass nuclear safety issues, particularly with regard to the potential for fire damage to result in the common mode failure of redundant trains of systems, and components important to the safe shutdown of the reactor. Following its investigations into the Browns Ferry fire, the Nuclear Regulatory Commission (NRC) promulgated guidance documents, which ultimately developed into mandatory regulations, necessary to assure the implementation of a fire protection program that would address nuclear safety concerns. The new criteria that evolved, contain prescriptive design features, as well as personnel and administrative requirements the Commission determined to be necessary to provide a defense-in-depth level of protection against the hazards ofmore » fire and its associated effects on safety related equipment. These criteria are primarily contained in Appendix R of Title 10 to the Code of Federal Regulations (10 CFR 50). Since 1983, various members of the Department of Nuclear Energy (DNE) at Brookhaven National Laboratory (BNL) have provided technical assistance to the Nuclear Regulatory Commission (NRC) in support of its evaluations of fire protection features implemented at commercial nuclear power stations operated in the US. This paper presents a discussion of the insights gained by the author during his active participation in this area.« less


Objiective:To establish an HPLC - MS/ESI method to determine valproic acid(VPA) in human serum. The method was utilized in therapeutic drug monitoring (TDM) of valproic acid. Method:Waters XTerra C18 (150 mm×3.9 mm,5μm)column was used with temperature of 45℃. The mobile phase consisted of 10 mmol·L-1 ammonium acetate-acetonitrile (60:40) ,at a flow rate of 0.80 mL·min-1. Diclofene(?) was internal standard. Valproic acid was quantitated by selected ion recording (SIR) with negative ESI. Serum was deposited by acetonitrile directly. Results:The minimal detectable serum drug concentration was 0.50μg·mL-1. The calibration curve was linear in the range of 7.25-188.10μg·mL-1(r=0.9997). The average recovery was between 98.7% and 105.1%. Inter - day and intra - day RSD were less than 10% (n=5). Conclusion:The method is simple, sensitive and accurate. It is suitable for the monitoring of valproic acid concentration in serum.


8 JUNE 2001 A N article in The Age (16 April 2001) by Kenneth Davidson was titled 'How big business captured Premier Bracks'. The article contended that the Bracks Government has adopted many of the policy approaches of its Liberal predecessor. Davidson sought a reversal. He argued that the Bracks Government should distribute the $200 million windfall from the GST to teachers and nurses rather than use it to attract business activity and privatesector jobs. The article's conventional Age anti-business line is an important pointer to wider phenomena. The Bracks Government, like that of Carr in NSW and Beattie in Queensland, sees the road to longevity in promoting the form rather than the substance of policies that push more funds to social services. People have to be paid off for providing support— and, notwithstanding Davidson's views, nurses and teachers have been generously rewarded. But securing a new dynasty means making changes at the edges rather than radical restructuring. And although, in Victoria's case, many would like to dismantle the Kennett privatizations, the Labor Administration knows that this is both impossible and undesirable, except in marginal cases such as the ambulance service. If the Victorian Labor Government can maintain this approach, it will avoid the excesses of its predecessors which have, in the past, invariably swept ALP governments from power. Achieving and maintaining government requires tapping the huge The Pendulum Swings Robbing the Rich Pays Electoral Dividends

As CDs continue to shrink, lithographers are moving more towards using off-axis illumination schemes to increase their CD budget. There have been several papers over the last few years describing various custom illumination profiles designed for application specific optimization. These include various annular and quadrupole illumination schemes including weak quadrupole, CQUEST, and QuasarTM. Diffractive optics, if incorporated into the design of the illumination system, can be used to create arbitrary illumination profiles without the associated light loss, thus maintaining throughput while optimizing system performance. Diffractive optical elements used to generate efficient illumination profiles for 248 nm and 193 nm excimer laser-source scanners, have been reported and realized in fused silica. The fabrication of such elements in calcium fluoride (CaF2), for use in 157 nm wavelength lithographic projection tools has been developed and is presented in this paper. Three different categories of elements are shown: large-diagonal-cluster diffusers, medium- and small-rectangular-cluster diffusers. The diffusers were fabricated as binary phase devices, in order to determine calcium fluoride processing capabilities.


In practical surveillance applications, methods for multiple camera tracking have to deal with many challenges such as noises and errors in estimating system parameters. In this paper, we propose a distributed multiple camera tracking system that can track multiple persons in real time under challenging conditions such as inaccuracy from calibration, noises from background and lighting changes. The system combines a network of cameras located around the environment, a central process unit and mobile devices. Experimental results show that our system has already performed well in military training.


A particular limestone named Godavari Limestone is encountered in Godavari delta region of Early Eocene age. This limestone has been mapped and used as a marker horizon in seismic stratigraphic studies of the area because of its high acoustic impedance contrast with the surrounding clastics. The limestone has been interpreted to be of the platform type deposHed in a shallow marine shelf environment. Shelf edge has also been mapped which can consist of good petroliferous deposits of carbonate buildups.

Today, rapidly developing technological innovations affect and change all sectors. Health sectors are inevitably involved in a digital transformation. In this transformation, IoT technology plays an important role, which enables many devices to connect and work together. IoT basically converts systems into intelligent systems that work together using sensors, connection methods, internet protocols, databases, cloud computing and analytics as infrastructure. In this respect, it is necessary to establish the necessary technical infrastructure and establish a suitable environment for the establishment of intelligent hospitals. Finally, a capability model has been developed in order to measure digital performance of Turkey. For Turkey health sector, technology assessment report is presented based on survey results and HIMMS EMRAM data.


Empirical modeling of vegetation dynamics can be used for predictive pur- poses. The goal of the present study is to construct and evaluate possible approaches for empirical modeling of vegetation dynamics, and to investigate their potential use in planning and management. An empirical model of mediterranean vegetation dynamics was constructed using a case study of vegetation change in an area in the Galilee mountains, northern Israel, between 1964 and 1992. Present vegetation in any location was modeled as a function of past vegetation and environmental factors (e.g., topography and various disturbances); future vegetation was then modeled as a function of current vegetation and effects of environmental factors. In order to assess model performance, we compared the actual vegetation map with maps representing model realizations for the study area and for an external validation area. Three types of measures were used to compare the predicted and actual vegetation maps: overall vegetation composition, pattern indices, and cell-by-cell match. We compared the performance of logistic vs. linear models and of stochastic vs. deterministic realizations of a logistic model. Our results indicate that landscape-scale vegetation dynamics can be fairly well modeled using a few biologically important variables. The logistic and linear models had similar performance, in spite of the reduced information on which the logistic models were based. The use of only a 4% sample of the database resulted in a negligible reduction in model performance. Model performance was reduced, but was still fair, when applied to an external area. The merits and limitations of this modeling approach are discussed in comparison with other approaches for modeling vegetation dynamics.


This study is to evaluate the snowmelt impact on dam inflow for the Chungju Dam watershed 6,642.0 ㎢ using Terra MODIS(Moderate-Resolution Imaging Spectroradiometer) and Soil and Water Assessment(SWAT). To determine the SWAT snowmelt parameter; snow cover depletion curve(SCDC) the snow depth distribution(SDD) using Terra MODIS was used, the snow depth was spatially interpolated using snowfall data of ground meteorological stations. For 10 sets(2000-2010) data during snowmelt period(November-April), the sno50cov parameter, that is, the 50% coverage at a fraction of SCDC which determines the shape of snow depletion process, showed the values of 0.4 to 0.7. The SWAT model was calibrated with average R² of 0.54 using the sno50cov of each year. The 10 years average streamflow during snowmelt period was 104.3 mm which covers 12.0% of the annual streamflow.


One reason ACOs, and similar types of healthcare models around the world, are growing is to reduce the high rate of patients returning to the emergency room and or being readmitted to the hospital. According to the Medicare Payment Advisory Commission, in the United States, the current 30-day readmission rate for Medicare patients is greater than 20 percent.1 As a result, many hospitals are forfeiting Medicare funds, which can result in a loss of millions of dollars.


Background: Lapidus (first metatarsocuneiform joint) arthrodesis is an established procedure for the management of hallux valgus. This study investigated the utility of fixation with a medial locking plate with adjunct compression screw versus fixation with two crossed screws.

Methods: Eight pairs of fresh-frozen human specimens were used in a matched paired test. Bone mineral density (BMD) was measured with peripheral quantitative computed tomography (pQCT). Fixation with two 4-mm-diameter crossed screws was compared versus a medial locking plate (X-Locking Plate 2.4/2.7; Synthes, Solothurn, Switzerland) with adjunct 4-mm-diameter compression screw. The specimens tested in a four-point bending test. Parameters obtained were initial stiffness; plantar joint-line gapping after one cycle, 100 and 1000 cycles; and number of cycles to failure. Failure was defined as ≥ 3 mm plantar gapping displacement.

Results: The groups did not differ significantly with regard to BMD (p = 0.866) and initial stiffness (p = 0.889). The plate-and-screw construct showed significantly less movement during testing, and significantly (p = 0.001) more cycles to failure than did the crossed-screw construct. There was a significant correlation (crossed-screw construct: p = 0.014; plate-and-screw construct: p = 0.010) between BMD and the number of cycles to failure.

Conclusions: Under cyclic loading conditions, the construct using a medial locking plate with adjunct compression screw was superior to the construct using two crossed screws.

Clinical Relevance: The medial locking-plate technique described holds promise for shortening the time off weight-bearing and for reducing the risk of non-union.

Cultural properties which consist of wood, so-called wooden cultural properties have historical, aca-demic, or aesthetic worth. In order to preserve wooden cultural properties, it is necessary to under-stand the materials and their deterioration condition, and then apply to them an appropriate conservation and restoration treatment. In conservation and restoration of wooden cultural properties, various scientific methods have been applied as well as traditional restoration techniques. This paper presents an overview of scientific investigations, conservation treatments and restorations for wooden cultural properties, and future prospects will be discussed. 主に木材を材料として構成される木質文化財は,歴史的,学術的,あるいは芸術的価値を有す


Abstract Alkaline hydrolyses of 2-propyl-2-oxo-1,3,2-dioxaphosphorinane and 2-iso-propyl-2-oxo-1,3,2-dioxaphosphorinane were studied in aqueous mixtures of dioxane, dimethylsulfoxide and acetone. The rate constants were determined at various temperatures, and thermodynamic reaction parameters were evaluated. The rate constant (k) of hydrolysis is found to be a function of both the polarity of the solvent mixture and the ratio volume of aprotic solvent and water in the mixture represented by value. The rate of hydrolysis can be expressed as a function of the dielectric constant as well as due to the hydration by the organic solvent molecules, making the HO− stronger nucleophilic. The hydrolysis demonstrates an isokinetic relationship, suggesting that the reaction mechanism is similar in the various solvent systems studied.


The article encompasses the four main zones of incidence, in the Romanian legislation, of the consumer's right to retract the prior consent, namely the contracts concluded outside commercial spaces, contracts agreed at distance, including electronic bargains, credits offered to consumers and time-sharing contracts. First, we briefly discuss the various possibilities of consent withdrawal, as described by national law and examine the discretionary character of withdrawal rights. Next, attention will be given to concrete aspects of retract exercise and to the question whether it is possible for retracts to be seen as cases of progressive formations of agreements. Finally, some attention will be given to the sanctions which can be found in Romanian Consumption Law, as attached to the violation by professionals of consumers' right to revoke the prior consent.


The structure,control logic,operation,test,and application situation of an inner-positioned automatic quasi-synchronous system used for 330 MW unit no.8 in Huaneng Haikou Power Plant,which is constructed by bringing the automatic quasi-synchronous system into DCS,have been presented.A comparison with the traditional single-purpose synchronous system shows that the inner-positioned synchronous system in DCS has advantages of few external cables,small investment for equipments,and little amount of installine works etc.,but it has shortcomings of non-adjustable pulse width for output commands,and negative values are included in settings of frequence difference and voltage difference.


At the beginning of the current year, an event occurred that caused a significant series of modifications in those aspects related to the teaching of classes -we are referring to the pandemic caused by COVID-19a situation that almost instantaneously altered any projection related to the normal development of the academic calendar. In accordance with the situation described, the Universidad Nacional de La Matanza (UNLaM) decided to continue with its academic activities in the non-face-to-face mode, using as technological support the Materias Interactivas en Línea (MIeL) platform -a virtual teaching-learning environment fully developed by university teacherswith the complement of the MS-TEAMS tool for the delivery of classes in videoconference mode. We refer to the problems, needs, uncertainties, tensions and opportunities A. Rusticcini, J. De Cicco and L. Morrone, "La educación no presencial en el contexto del COVID-19: el caso de la plataforma Materias Interactivas en Línea de la Universidad Nacional de La Matanza ," pp. 340-343 TE&ET N°28 Especial | Marzo 2021 | ISSN 1850-9959 | UNLP Facultad de InformáticaSecretaría de Postgrado 341 that were generated during the course of this experience in this article.


The reaction of 1,4-dichlorobenzene with NaNH2 in liquid ammonia gave 4-chlorobenzyne which was trapped by the ammonia solvent to give a 63:37 mixture of 4-chloro and 3- chloroaniline, respectively, which is in contrast to an earlier report that 4-chlorobenzyne undergoes regioselective amination at carbon-1. Furthermore, 4-halofluorobenzenes (X=Cl, Br, and I) reacted with LDA to eliminate the less basic halogen atom, i.e. the better leaving group, to give 4-fluorobenzyne, which reacted with LDA to give a 70:30 mixture of 4-fluoro- and -N,N- diisopropyl-3-fluoroaniline, respectively. Attempts to trap 4-fluorobenzyne in the LDA-mediated reactions with furan gave mainly the aforementioned anilines plus a small amount of 6- fluorooxabenzonorbornadiene. However, 4-halofluorobenzenes (X = I, Br, Cl, F) when treated with tert-BuLi in furan at -70 °C eliminated fluoride ion to give the corresponding 4- halobenzyne, which were trapped by furan to the 6-halo derivatives of oxabenzonorbornadiene in high yields. In the case of 3-halofluorobenzenes, 3-haloarynes are generated in the normal way by the loss of the better leaving halogen atom and were also trapped with furan to give corresponding 5-halooxabenzonorbornadienes. An explanation in terms of the relative base strengths of LDA and t-BuLi and influence of solvent on the aryne generation is presented.


The purpose of this study is to explore the sensitivity of the National Photovoltaic Research Program goals to changes in individual photovoltaic system parameters. Using the relationship between lifetime cost and system performance parameters, tests were made to see how overall photovoltaic system energy costs are affected by changes in the goals set for module cost and efficiency, system component costs and efficiencies, operation and maintenance costs, and indirect costs. The results are presented in tables and figures for easy reference. An analysis is made of the effects of regional differences in competing energy costs and solar insolation levels on the competitiveness of photovoltaic systems. The sensitivity of competing energy costs (coal, combustion turbine, and combined cycle oil-fired generators) to escalation rates for capital and fuel are explored. Alternative tracking configurations (fixed, one-axis, and two-axis tracking) are also introduced into the sensitivity analysis. Goal values for photovoltaic system parameters were reviewed on the basis of the most recent research findings. Sensitivity tests were made to see how research progress in areas such as power-related balance of system cost affected the combinations of module cost and module efficiency that meet program goals for system energy costs.


ordering of the oblique cases established by Apollonius Dyscolos according to criteria of shared semantic features into association with a new ordering of local and temporal relationships (whence-where-whither and past-present-future) but this is far from any proposal to explain all cases as having a local basis. Franco Cavazza discusses the quality and depth of the linguistic interests of Aulus Gellius, while Wilhelm Pfaffel examines the 'modernity' (for his own time) of Varro's etymological work. A most valuable contribution is Alan Kemp's translation with introduction and notes of the Grammnatike Techne attributed to Dionysius Thrax: a full edition is in preparation. Even Hovdhaugen is able to demonstrate that there was progress in Latin grammatical thinking between the third and sixth centuries A.D. by tracing the gradual development of a more sophisticated analysis of the Latin genera verborum in this period. Three articles relate the activity of grammarians to their social and historical context; Vivien Law offers a typological history of Latin grammars in the early middle ages, showing how the contents of grammars reflected the changing needs of the times; Robert A. Kaster considers the quite prestigious social position of grammarians in late antiquity which could have encouraged them to value their status as guardians of tradition rather than innovators, and Kees Versteegh, dealing with the Hellenistic period, insists on the distinction between standard (written) languages which grammarians were concerned to describe and colloquial forms of language which they systematically ignored, concluding that all written material, since it is influenced by the norms of literacy, is to be distrusted as evidence for developments of the spoken language.


Software reuse has been a long term goal of software developers. This goal has been rather elusive, but the widespread use of the object-oriented paradigm and other innovations in software development paradigms have led to renewed interest in this topic.
This dissertation describes a new approach for the identification of reusable object-oriented legacy software components. The approach is concept-driven, knowledge-based and tool-assisted and uses heuristics to aid in the natural language understanding of comments and identifiers in object-oriented code. The approach uses a reusability quality factors hierarchy, where low-level object-oriented metrics are used to predict reusability quality factors.
The automation of this approach is provided by the Program Analysis Tool for Reuse (the PATRicia system), which is a software tool that aids in program understanding and metrics analysis. It consists of the Conceptual Hierarchy for Reuse including Semantics (CHRiS) tool, which uses a knowledge-base in the form of a conceptual-graph based semantic net in the natural language understanding of comments and identifiers, and the Metrics Analyzer tool which calculates object-oriented metrics that are then used to predict reusability metrics.
These tool-aided methods are shown to work well by identifying and qualifying reusable components in several real world graphical user interface packages. This approach demonstrates that the identification of object-oriented legacy software components can be made significantly easier and more quantifiable than is possible using earlier techniques, which will aid greatly in promoting effective software reuse.


The renal elimination of methadone and its mafor metabolite by subfects on a methadone maintenance program was studied quantitatively. The concentrations of unchanged drug and metabolite in random urine samples were dose dependent. Urinary excretion was found to constitute the mafor excretory pathway at daily doses in excess of 55 mg. Excretion of methadone was markedly enhanced by acidification of the urine, while the metabolite was less affected by changes in urine pH. A sex difference in the pattern of excretion of methadone and its metabolite was found; it may be related to the rate of biotransformation of the drug.


Over the past few years, a wide range of device architectures employing organic-inorganic metal halide perovskite absorbers has been reported, with efficiencies exceeding 20%. Despite the tremendous progress, a number of key issues must be resolved before the wide-spread com-
mercialization will be possible. Some of the primary challenges include lead toxicity, long-term stability, and fast degradation upon exposure to humid atmosphere. Recent computational and experimental studies suggest that hybrid metal-halide perovskites act as an ionic-electronic conductor. The study of vacancy-mediated migration of I−, Pb2+ and CH3NH3− ions and their relative activation energies suggests that migration of halide vacancies, to and from the interfaces in the solar cell during its operation, is the main conduction mechanism. In this work, we are presenting high resolution synchrotron-based spectroscopic study, which indicates that the contribution of nitrogen into the conduction mechanism of methyl ammonium lead iodide-based (CH3NH3PbI3) perovskite films should not be neglected. The N1s core level and resonant X-ray photoelectron spectroscopy at the N1s-egde of the CH3NH3PbI3 films are discussed in detail.


Strong and tough structural materials are a challenging materials engineering problem that has drawn considerable attention among the materials community. Here we demonstrate that ternary supramolecular ensembles of cellulose nanocrystals-polyvinyl alcohol-glucose by evaporation-induced corporative assembly achieved simultaneous enhancement on the stiffness and toughness with the Young's modulus of 13 GPa at the work-of-fracture of 1.1 MJ·m–3. Compositional alteration led to stiff and tough ternary ensembles with the Young's modulus up to 14.7 GPa and the toughness up to 12.1 MJ·m–3, respectively. Concurrent enhancement in the stiffness and toughness was owing to the multiscale deformation involving weak interactions and helicoidal organization, leading to more efficient energy dissipation. The freestanding transparent films of the ternary ensembles exhibited dynamic selective reflection of left-handed circularly polarized light in response to mechanical and chemical stimuli. The combination of the mechan...


The drainage basin of Mayo river in the municipalities of San Pablo and La Cruz, Narino State, is an example of a volcanic shaped filled valley. Dona Juana, Animas and Cerro Petacas are volcanoes that have been previously considered as Dona Juana volcanic complex. The geology of the zone is represented by several units of volcanic origin, which lie on the methasedimentary rocks of Quebradagrande Complex and some hypoabisal igneous bodies. The catchment of Mayo river has been filled with products of these volcanoes, and partially drained out, in several occasions. Volcanic behavior of the complex and specifically the Dona Juana volcano, represented by some deposits of the Mayo river, shows that it had been dominantly of explosive type with some sporadic effusive episodes. The main volumes are constituted by ash and pumice flow, ash and blocks and debris flow deposits, forming in some cases ignimbrites units. With the recollected data until now, an evolutive activity history of the volcanoes complex is proposed. Three eruptive epochs are outlined, which are characterized each of one for presenting many different volcanic deposits with an accumulated thickness of 350m.

It is now well established that a single subcutaneous injection of cadmium chloride produces damage in the rat and mouse testis and proximal portion of the head of the epididymis (PHE).1This progresses to a state of irreversible atrophy and fibrosis of the organ in the course of a few weeks. It is also known that such damage in time evokes a castration effect.' Although the changes start in the interstitial tissue, they ultimately involve the tubules, so that spermatogenesis ceases and sterility results. The early changes are characterized by capillary congestion, thrombosis, and interstitial edema followed by necrosis and fibrosis.'-9 The exact mechanism by which cadmium chloride produces these changes is not clear. It has been suggested that primary damage takes place in the endothelium of interstitial capillaries in testis,1 the internal spermatic artery, the pampiniform plexus, and their branches.4 The changes that follow are secondary to this effect.'-9 Recent observations 10 indicate that an increased capillary permeability and alterations of blood flow also contribute to the damage. Some studies suggest that the action of cadmium is directed toward spermiogenic epithelium and involves the inhibition of certain enzymes. This view is supported by the fact that a simultaneous administration of zinc,1"3'4 selenium,11"12 or thiol compounds 13 protects the testis from the damaging effects of cadmium. Such evidence supports the enzymeinhibition concept, but the conclusion that spermiogenic epithelium is the primary target is open to question since it has been shown by autoradiography that the concentration of '09Cd is lower in seminiferous tubules than in the interstitium of the testis.'4 This indicates that the relation between concentration and damage is unclear. Furthermore, in the same study14 it was shown that such organs as kidney and liver accumulate much higher concentrations of cadmium than the testes though no damaging effects are seen on gross and microscopic examina-


Metal-on-metal (MOM) retrieval studies have demonstrated that CoCr bearings used in total hip arthroplasty (THA) and resurfacing (RSA) featured stripe wear damage on heads, likely created by rim impact with CoCr cups. 1-3 Such subluxation damage may release quantities of large CoCr particles that would provoke aggressive 3 rd -body wear. With RSA, the natural femoral neck reduces the head-neck ratio but avoids risk of metal-to-metal impingement (Fig. 1). 4 For this study, twelve retrieved RSA were compared to 12 THA (Table 1), evaluating, (i) patterns of habitual wear, (ii) stripe-wear damage and (iii) 3 rd -body abrasive scratches. Considering RSA have head/neck ratios much lower than large-diameter THA, any impingement damage should be uniquely positioned on the heads. Twelve RSA and THA retrievals were selected with respect to similar diameter range and vendors with follow-up ranging typically 1–6 years (Table 1). Patterns of habitual wear were mapped to determine position in vivo. Stripe damage was mapped at three sites: polar, equatorial and basal. Wear patterns were examined using SEM and white light interferometry (WLI). Graphical models characterized the complex geometry of the natural femoral neck in coronal and sagittal planes and provided RSA head-neck ratios. 4 Normal area patterns of habitual wear were similar on RSA and THA bearings. The wear patterns showing cup rim-breakout proved larger for RSA cups than THA. Polar stripes presented in juxtaposition to the polar axis in both RSA and THA (Fig. 1). As anticipated, basal stripes on RSA occurred at steeper cup-impingement angles (CIA) than THA. The micro-topography of stripe damage was similar on both RSA and THA heads. Some scratches were illustrative of 3 rd -body wear featuring raised lips, punctuated terminuses, and crater-like depressions (Fig. 2). Neck narrowing observed following RSA procedures may be a consequence of impingement and subluxation due to the small head-neck ratios. However, lacking a metal femoral neck, such RSA impingement would not result in metal debris being released. Nevertheless it has been suggested that cup-to-head impingement produced large CoCr particles and also cup "edge wear" as the head orbits the cup rim. 4 Our study showed that impingement had occurred as evidenced by the polar stripes and 3 rd -body wear by large hard particles as evidenced by the wide scratches with raised lips. We can therefore agree with the prior study, that 2-body and 3rd-body wear mechanisms were present in both RSA and THA retrievals.


An estimator of the correlation between Italian and U.S. Stock Returns is introduced. The properties of the estimator are invariant with respect to a wide class of GARCH models. The empirical evidence shows the existence of a positive correlation between Italian an U. S. stock returns.


Sun-photometry has a potentially important role to play in the atmospheric correction of airborne remotely sensed imagery. However, some understanding of the principles and limitations of Sun-photometry is vital to the successful utilisation of the technique for this purpose. This paper introduces the principles of Sun-photometry. It describes instrument characteristics, with particular reference to the EPFS Cimel CE 318-2. Sun-photometer measurements, the retrieval of atmospheric parameters and calibration issues are explained.


In a recent Wall Street Journal article titled "The Simple Idea That Is Transforming Health Care" (Landro, 2012), well-being is touted as a strategy that is fundamental to achieving improved health outcomes. A study published in Population Health Management (Harrison, Pope, Coberley, & Rula, 2012) was cited that found that higher self-reported well-being was associated with fewer hospitalizations, ER visits, and medication use prompting the authors to conclude that well-being improvement efforts represent a promising approach to decrease future health care utilization and expenditures. Well-being is not a particularly new concept, but perhaps an idea whose time has come. In 1946, the World Health Organization defined health as a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity. More than 30 years ago, Aaron Antonovsky (1987), a professor of sociology, coined the term salutogenesis to describe an approach to care that focuses on factors that support human health and wellbeing, rather than on factors that cause disease. Spirituality and well-being are closely intertwined, and for many, spirituality affects all aspects of well-being. Well-being is a state of being in balance and alignment in body, mind, and spirit. It is a state in which people describe themselves as feeling healthy, content, purposeful, peaceful, energized, in harmony, happy, prosperous, and safe. The word spirit in Hebrew is ruah, which translated means wind, breath or air, that which gives life. While defined in many different ways, at the core, spirituality literally means life giving or sustaining. This special issue of the Western Journal of Nursing Research highlights research and scholarship that focuses on spirituality and touches on many dimensions of the Well-Being Model developed by the University of Minnesota Center for Spirituality and Healing. As illustrated in Figure 1, well-being is affected by health, purpose, relationships, community, security, and the environment. Guest Editorial


The present invention relates to a device (1) for collecting the fluid of the blood, etc. flowing from the wound, and the unit (1) comprises a contact device (17) for contacting the blood or the like in the wound, the contact device 17 includes a plurality of pores (19) for absorbing fluid such as a blood contact by the contact device 17 in the interior of the contact device 17.


The current WWW technology in the Internet is characterised by a number of problems. Performance is poor due to the lack of suitable caching and propagation methods for frequently accessed documents, finding information is difficult since WWW has no built-in directory service. In this paper the functionality of a hypermedia information browsing (HIB) proxy server is described, as well as more details about the way it is implemented. In the European ACTS DOLMEN (Service Machine Development for an Open Long-term Mobile and Fixed Network Environment) project two basic ways have been identified of providing information browsing on the OSAM Platform, that is, the Open Service architecture for a mixed fixed and mobile environment. These are called the gateway approach and the full OSAM approach. It is decided to implement a browsing application based on the gateway approach. The gateway approach involves two subsystems: (1) HIB browser running on the end-user's terminal; and (2) HIB proxy server running on a service node. The objective of the gateway approach is to provide an enhanced Web browsing service for end-users on the OSAM platform. The TINA sessions and stream communication are used between the HIB browser and HIB proxy server.


The article explores the extent of mental health of patients suffering from malignant hematological diseases and social supports. The method adopts self quantity evaluation form on symptoms (SCL-90) and questionnaires on quantity social support to investigate 143 patients suffering from malignant hematological disease. The result shows that the factor scores for patients suffering from malignant hematological disease from SCL-90 are not significantly different from the routines in China, but 4 factors (body, depression, terror and anxiousness) are of symptoms. And the factors differ, in different degrees, in sex, age, duration of stay in hospital, affording capacity etc. the social supports to the patients suffering from malignant hematological disease may divided into 3 dimensions: humane support, extensiveness of sources of support and usage of support. The conclusion is: patients suffering from malignant hematological diseases have relatively more mental problems. one should pay great attention to them, and they need more supports from various circles of the society.

The central data reconstruction of the ATLAS experiment of LHC is a very challenging task, involving large-scale computing and a wide variety of data formats, applications and software versions. To handle all this complexity, we have developed a powerful data-driven auto-configuration mechanism and a unified configuration interface that provides a lot of flexibility: Reco_trf. The auto-configuration mechanism consists of inspecting the meta-data of each job's input file to automatically derive the configuration parameters relevant for the input format and the requested tasks. This also simplifies considerably the configuration of jobs from ordinary users, who can use the same script to run without modification on real or simulated data, on files belonging to different major production, using raw or derived input data of any format. Possible intermediate algorithms are automatically scheduled according to the content of the input file. Reco_trf is a so-called "job transformation" interface used for all centralized production tasks at CERN's TierO and on the Grid, and is also largely used by normal users. Reco_trf adds a lot of flexibility in the Production systems by allowing the execution of arbitrary python commands without building new software releases, while still bookkeeping this information in the production databases.


Two new copper(II) compounds of chloranilate and 2,2':6',2' '-terpyridine have been synthesized, and the structures have been solved by the single-crystal X-ray diffraction method. The crystal structure of [[Cu(2)(CA)(terpy)(2)][Cu(CA)(2)]](n)(1), where H(2)CA = chloranilic acid and terpy = 2,2':6',2' '-terpyridine, consists of two modules, the dimer unit [Cu(2)(CA)(terpy)(2)](2+) and the anionic mononuclear unit [Cu(CA)(2)](2)(-), forming an alternated chain. The chain is stabilized by semicoordinating and additional but efficient secondary bonding interactions. The crystal structure of [[Cu(2)(CA)(terpy)(2)(dmso)(2)][Cu(CA)(2)(dmso)(2)](EtOH)](n)(2), where dmso = dimethyl sulfoxide, consists of solvent molecules and two discrete modules, the dimer unit [Cu(2)(CA)(terpy)(2)(dmso)(2)](2+) and the anionic mononuclear unit [Cu(CA)(2)(dmso)(2)](2)(-). The dimer units form a layer by secondary bonding interactions, and the monomer units and ethanol molecules are introduced between the layers. The magnetic properties of 1 and 2 have been investigated in the temperature range 2.0-300 K. A weak ferromagnetic interaction was observed in 1, J(a) = 2.36 cm(-)(1) and zJ(b) = -0.68 cm(-)(1) while no exchange coupling was observed in 2.


Introduction The SARS-CoV-2 infection has been advocated as an environmental trigger for autoimmune diseases, and a paradigmatic example comes from similarities between COVID-19 and the myositis-spectrum disease associated with antibodies against the melanoma differentiation antigen 5 (MDA5) in terms of clinical features, lung involvement, and immune mechanisms, particularly type I interferons (IFN). Case Report We report a case of anti-MDA5 syndrome with skin manifestations, constitutional symptoms, and cardiomyopathy following a proven SARS-CoV-2 infection. Systematic Literature Review We systematically searched for publications on inflammatory myositis associated with COVID-19. We describe the main clinical, immunological, and demographic features, focusing our attention on the anti-MDA5 syndrome. Discussion MDA5 is a pattern recognition receptor essential in the immune response against viruses and this may contribute to explain the production of anti-MDA5 antibodies in some SARS-CoV-2 infected patients. The activation of MDA5 induces the synthesis of type I IFN with an antiviral role, inversely correlated with COVID-19 severity. Conversely, elevated type I IFN levels correlate with disease activity in anti-MDA5 syndrome. While recognizing this ia broad area of uncertainty, we speculate that the strong type I IFN response observed in patients with anti-MDA5 syndrome, might harbor protective effects against viral infections, including COVID-19.


Objective: Since open surgical evacuation of basal ganglia hemorrhage (BGH) as had been proved did not lead to the desired benefit for the patients, we used minimally invasive clot lysis by injection of recombinant tissue-type plasminogen activator (rtPA).
Methods: Patients with spontaneous BGH with or without accompanied intraventricular hemorrhage were included in the study. Following diagnosis of BGH by CT scanning, a catheter was inserted through a small burr hole under neuro-navigation assistance into the centre of hemorrhage and three mg rtPA was injected for three consecutive days. CT scans were performed daily to determine the volume of the hemorrhage. The size of hemorrhage was calculated using the ABCs measuring method. The clinical condition of the patients was classified using the Glasgow coma scale (GCS) and Glasgow outcome scale (GOS). Statistical analysis was performed using the Fisher's exact test and Chi-square with Yates' correction. The p-values were calculated with two tails and statistical significance was estimated as p-value <0.05.
Results: The procedure was performed on 22 patients (11 females and 11 males). The mean age of the patients was 64 years (range: 44–80 years). Among the patients, 7 (31.8%) were considered in a poor clinical condition, 11 (50%) in an intermediate condition and 4 (18.2%) in a good clinical condition. The total mortality was calculated with n=3 (13.64%). The mean volume of hemorrhage before treatment was 35.14 mL (range 11.5 mL – 67.15 mL). After the third injection, a mean volume reduction of 73.05% could be achieved. Considering the accuracy of the neuro- navigation dataset, correct placement of the drainage in the assumed center of hemorrhage was confirmed in all cases by CT scanning after the first injection. Re-bleeding occurred in 4 cases (18.2%).
Conclusion: Treatment with rt-PA in BGH seems an easy, safe and minimally invasive alternative to open surgical hematoma evacuation and it might be more favorable compared to conservative treatment. In our study, we achieved a mean volume of hemorrhage reduction of 73% after 3 days. Clot lysis alone was not the only predictive factor for a better outcome. Outcome prognosis should take several other co-factors into account such as the age of the patient and the GCS at the time of Admission. Large prospective and randomized trials are still necessary to answer these open questions


This study aims to determine the periodicity feeding climbing perch caught in the waters of the swamp Malintang-Baru district-Gambut-Banjar district of South Kalimantan. The number of samples of fish caught 180 tail using fishing gear cash net. pick up a fish sampling during 24 hours, with an interval of 4 hours, ie at 20.00, 24.00, 04.00, 08.00, 12.00, and 16.00. Feeding periodicity analysis performed by calculating the fullness of the stomach contents are expressed as a percent. To determine the relationship between feeding periodicity with the fullness of the stomach contents, use statistical tests completely randomized design (CRD). The analysis showed that feeding periodicity affect the fullness of the stomach contents, at 20:00 fullness of stomach contents which is 80.9191% of maximum fish activity etching in taking food. At 24.00 (50.9722%) and 12.00 (47.7563%) of the climbing perch also actively take food, but not as active at 20:00. whereas 04.00 (12.4054%), 08.00 (21.1733%), and 16.00 (7.1414%) say of the climbing perch not perform activities takers.


In a world where religion played a far greater role in society than it does in the modern day, it is no surprise that those living in the medieval period desired a close association with the church. Nowhere is this association clearer than with the aristocracy of the time. This project looks in detail at the close relationship between Anglo-Norman castle lords and monastic institutions, considering the different ways in which they patronised religious houses and the spiritual and social gains that they could enjoy as a result of their support. By looking at the study area of the AngloWelsh Marches, an overview is built up of the connections between the monastery and the castle, before individual high status Anglo-Norman families and their associated religious institutions are considered to give a more complete and detailed picture. In addition to the social aspects of this association, the wider environments of monastic sites are also studied, raising notable similarities between religious and high status secular landscapes.


In this Letter, the maximum likelihood (ML) estimator for the parameters of a real sinusoid in additive white Gaussian noise using irregularly-spaced samples is derived. The ML frequency estimate is first determined by a one-dimensional search, from which optimum amplitude and phase estimates are then computed. It is shown that the estimation performance of the ML method can attain Cramer-Rao lower bound when the signal-to-noise ratio is sufficiently large.

We investigate the electronic and optical properties of free-standing and epitaxially strained ${\mathrm{Si}}_{1\ensuremath{-}y}{\mathrm{C}}_{y}$ alloys. We first determine the microscopic atomic structure of the alloys using the semi-grand-canonical Monte Carlo method and empirical interatomic potentials. For the calculation of the electronic and optical properties of the alloys we employ a supercell geometry and an empirical tight-binding model, which was fitted to reproduce the relevant band structures obtained from first-principles calculations. Our approach allows for a thorough investigation of C alloying and strain effects on the band gap, the band offsets, the effective masses of the upper valence and lowest conduction bands, and the optical properties. Our results are in very good agreement with experiment.


The study of ovarian morphology in sheep during age periods, when this organ undergoes a significant restructuring, is of important theoretical and practical im-portance. In sheep farms in the Eastern zone of the Stavropol territory, histological stud-ies of sheep ovaries in postnatal ontogenesis were performed to determine the thickness of the rudimentary epithelium, the protein envelope, the thickness of the cortical and cerebral layer, as well as the diameter of the follicles and yellow bodies. The results re-vealed that sheep of Stavropol breed set cat-alog thickness of epithelium is in the range of 2.07±0,19-of 13.73±0,41 μm, the thick-ness of the tunica - of 4.91±0,21-of 18.96±0,49 μm, the thickness of the cortical layer - 84,28±6,48-120,55±1,98 μm, and the thickness of the medulla wins with 52.86±2,56-106,85±of 1.76 μm.A signifi-cant increase in these structures in the ovary occurs at the time of puberty (six months), further there is a slowdown in the growth rate of layers in the ovary and by nine to twelve months it remains unchanged, which indicates the completion of the development of the organ. Analysis of the dynamics of the diameter of follicles and yellow bodies showed that the diameter of primordial (2.62±0.03-8.37±0.69 microns), primary (25.28±0.97-46.48±5.27 microns), secondary (35.20±3.82-91.57±5.28 microns) follicles increases with age. Tertiary follicles in the ovary are detected at three months, and yel-low bodies from six months of life and their diameter is in the range of 372.56±60.28-526.17±32.78 microns and 105.32±0.80-117.12±0.62 microns, respectively. The reli-able data obtained by us on changes in the diameter of follicles and yellow bodies are probably related to the active influence of gonadotropins on the ovaries, which are re-sponsible for the growth, maturation of folli-cles, ovulation and formation of yellow bod-ies.


The stability of alumina-pillared montmorillonite clays, prepared at various Al/clay ratios, was investigated by compaction at various pressures. The physical properties of the pillared clays, before and after compaction, were studied by powder XRD and nitrogen sorption. We found that the Al/clay ratio used to prepare the pillared clays (and therefore the resulting pillar density) is not a critical factor in determining the overall mechanical stability. However, pillared clays with a higher density were subject to greater decreases in textural properties (surface area and pore volume) after compaction. It was found that the pillared clays (regardless of pillar density) are generally stable up to ca. 5.7 tons cm-2. Mechanical pressure below 5.7 t cm-2 resulted only in small decreases in basal spacing, surface area, and pore volume. This was, however, accompanied by significant changes in the proportion of micropore surface area and pore volume. Compaction at a pressure of ca. 7.5 t cm-2 decreased the surfa...


A class of pseudorandom sequences over GF(p/sup m/) which are the generalization of m-sequences are constructed, and the periodic auto- and cross-correlation functions of the generalized m-sequences are analyzed. The cross-correlation function of two generalized m-sequences over GF(p/sup m/) with period p/sup mn/-1 is calculated in terms of the cross-correlation of two smaller m-sequences over GF(p) with period p/sup m/-1. Classes of sequences which have small peak values of cross-correlations are obtained.<<ETX>>


A simple basic model for describing proton-nucleus (p+A) and nucleus-nucleus (A+A) collisions has been the intra-nuclear cascade model, where the interactions are simulated by a sequence of binary nucleon-nucleon (NN) collisions. This model helped to establish many scientific concepts and also creates the foundation for more modern simulation codes, especially at low and intermediate energies. In this paper, we present a new Monte Carlo model for p+A and A+A collisions at high CERN Large Hadron collider energies. The model implements HIJING code with a collective cascade recipe, that induces lightening-like effect in a large nucleus. A single collision (lightening) event is shown to be a complex process: A primary interacting nucleon passes its energy to the surrounding nucleons in a large nucleus. This new simulation code is shown to be good to reproduce the Large Hadron collider (LHC) data, especially the charged particle pseudorapidity density in p+Pb and Pb+Pb collisions at LHC energies.

A 63-year-old man with a history of hypertension, paroxysmal atrial fibrillation, and dyslipidemia had a sudden intense chest pain radiating to his left arm, and he lost control of his legs. He was not on anticoagulant therapy and had no history of back trauma. During transport, he was hypotensive (blood pressure 88/51), his right arm was pale, and he was not able to move his legs. ECG showed inferolateral ST-segment depressions. He was given 250 mg aspirin and morphine for pain. With intravenous fluid-replacement therapy, his blood pressure rose and the activity of his legs improved. Aortic dissection was suspected, and the patient was urgently admitted to the surgical emergency room within the university hospital. In the emergency room, his blood pressure was 108/62. Cardiac and pulmonary auscultation and abdominal palpation were normal, and peripheral pulses were symmetrical. Computed tomography of the aorta revealed a hematoma next to the ascending aorta, raising a suspicion of type A aortic dissection reaching from the ascending aorta to the beginning of the left renal artery. The aortic valve was intact.

During an emergency operation, the ascending aorta and a part of the aortic arch were replaced with a prosthetic graft. The arrest time was 24 minutes, and closure of the aorta took 112 minutes. In the beginning, the patient needed vasoactive support because of hypotension but later on his hemodynamic was stable. However, the next day, the patient had to undergo a resternotomy because of postoperative bleeding. After the operation, he was hypertensive and was treated with antihypertensive medication.

The patient was extubated on the second postoperative day and mobilization was started the next day, when it was noticed that the patient could not stand on his feet and coordination of his lower limbs was impaired. On the fourth postoperative day, a neurologist …

ABSTRACT The landscape is a point of passage between the self and the world, the interior and the exterior, the near and the distant, the real and the imaginary: as such, it has become a privileged theme for the field of poetry aiming to reach the world in spite of the distance separating words and things. This paradoxical relationship is particularly inscribed in the motif of the horizon, defining the landscape while remaining unattainable: it serves as a threshold between here and elsewhere, the earth and the sky, the visible and the invisible. The interchanges that take place in this virtual space are at the very core of landscape poetics, especially prevalent in French and Francophone poetry since the Second World War: I will examine its historical, artistic, and literary implications. I will study the dynamics and aporias in Philippe Jaccottet's work, where images of the threshold, the door, and passage are recurring.

We explore several generalizations of Whitney's theorem -- a classical formula for the chromatic polynomial of a graph. Following Stanley, we replace the chromatic polynomial by the chromatic symmetric function. Following Dohmen and Trinks, we exclude not all but only an (arbitrarily selected) set of broken circuits, or even weigh these broken circuits with weight monomials instead of excluding them. Following Crew and Spirkl, we put weights on the vertices of the graph. Following Gebhard and Sagan, we lift the chromatic symmetric function to noncommuting variables. In addition, we replace the graph by an"ambigraph", an apparently new concept that includes both hypergraphs and multigraphs as particular cases. We show that Whitney's formula endures all these generalizations, and a fairly simple sign-reversing involution can be used to prove it in each setting. Furthermore, if we restrict ourselves to the chromatic polynomial, then the graph can be replaced by a matroid. We discuss an application to transitive digraphs (i.e., posets), and reprove an alternating-sum identity by Dahlberg and van Willigenburg.

Glyphosate (Tiller 480 SL), which is used extensively to control and inhibit weeds in terrestrial and aquatic ecosystems, has been blamed of harming non-targeted species like fish. This current study evaluated the acute and chronic impacts of glyphosate on the Arabian killifish (Aphanius dispar) collected from Southwestern Saudi Arabia at different levels of biological organization including behavioral and histopathological responses. Glyphosate toxicity (96 h LC50) to Aphanius dispar was determined at 115.25 mg/l after exposure to 60, 90, 120, 150, 180, 210, 240 mg glyphosate/l. Fish during the 96 h displayed abnormal behavioral changes: erratic movements, hyperactivity, rapid opercula and mouth movements, surfacing, hypoactivity, exhaustion and mortality. While, exposure of fish to 1/4th of the 96-h LC50 for two weeks, the gills and liver organs displayed histopathological alterations.


Damping of fixed offshore platforms is discussed on the basis of fullscale measurements of dynamic response of gravity platforms and jacket platforms. It is shown how the measured data indicate that the damping of these structure is highly non-linear in a way which gives that the commonly applied linear damping models are non-conservative. Furthermore, the sources of the non-linear damping is discussed and, finally, some comments are given on the possible effects of such damping to extreme dynamic response and fatigue life of deepwater platforms. .


The mammalian neocortex is composed of diverse neuronal and glial cell classes that broadly arrange in six distinct laminae. Cortical layers emerge during development and defects in the developmental programs that orchestrate cortical lamination are associated with neurodevelopmental diseases. The developmental principle of cortical layer formation depends on concerted radial projection neuron migration, from their birthplace to their final target position. Radial migration occurs in defined sequential steps, regulated by a large array of signaling pathways. However, based on genetic loss-of-function experiments, most studies have thus far focused on the role of cell-autonomous gene function. Yet, cortical neuron migration in situ is a complex process and migrating neurons traverse along diverse cellular compartments and environments. The role of tissue-wide properties and genetic state in radial neuron migration is however not clear. Here we utilized mosaic analysis with double markers (MADM) technology to either sparsely or globally delete gene function, followed by quantitative single-cell phenotyping. The MADM-based gene ablation paradigms in combination with computational modeling demonstrated that global tissue-wide effects predominate cell-autonomous gene function albeit in a gene-specific manner. Our results thus suggest that the genetic landscape in a tissue critically affects the overall migration phenotype of individual cortical projection neurons. In a broader context, our findings imply that global tissue-wide effects represent an essential component of the underlying etiology associated with focal malformations of cortical development in particular, and neurological diseases in general.


Ensuring that environments are designed to cater for those with decreasing orientation, perceptual and mobility skills, is an example of how environments are being changed to become more age and dementia friendly. However, environmental design should directly involve potential users of the environment to ensure that their views are accounted for. Four open-ended questions, focusing on orientation strategies, reasons for disorientation, and design preferences, were given to 32 older adults after they had completed a route learning task through an unfamiliar environment. A Content Analysis found a strong focus on participants' ability to memorize routes based on verbally encoding the route and on their ability to remember landmarks, with the reports linking closely to cognitive theories of navigation. Design suggestions included the importance of a homely and welcoming environment, memorable features, and access to the outdoors. The findings can be used inform age and dementia friendly design principles.


Diabetes mellitus is one of the most common disease of the endocrine system in the body that is diagnosed by metabolic malfunction in the metabolism of carbohydrates, fat and proteins. This disease involves most tissues of the body and the consequent deficiencies reduce their efficiency, cause infections and diseases in the body. Alloxan is a chemical which is used in inducing experimental diabetes in animals. In this research, 9 German shepherd dogs were provided, 5 of which was considered as our experimental group and the remaining 4 was considered as the control group. The necessary examinations were conducted to guarantee their health and the absence of diabetes was ascertained with intravenous glucose tolerance test (IVGTT). 100 mg/kg of alloxan monohydrate were given to the experimental group. After the administration, animals were obsevered for clinical symptoms. If the symptoms indicate death, samples tissue of coronary arteries were taken. Microscopic and ultra structural deficiencies were checked for. The endothelial cells of the coronary arteries showed vacuolization of cytoplasm with decreased transitional vesicles and thickened basal membrane. It was concluded that diabetes mellitus is a potent risk factor for the development of coronary atherosclerosis.

AIMS
To establish whether gender or N-acetyltransferase 2 (NAT2) genotype influence the urinary 17 U+17X/137X ratio after dosing with caffeine.

METHODS
Ninety-two nonsmoking individuals underwent caffeine phenotyping. NAT2 genotype was determined by the polymerase chain reaction followed by a restriction digest (PCR-RFLP).

RESULTS
The median ratio for urinary 17 U+17X/137X was 6.7 (range 1.45-18. 65). 55% of subjects were slow acetylators. Gender did not affect the metabolic ratio or NAT2 genotype. Mean 17 U+17X/137X ratio differed between fast (6.75) and slow (8.69) acetylators (95% CI for the difference, 0.32-3.56).

CONCLUSIONS
The findings are further evidence that the 17 U+17X/137X urinary ratio is not a robust measure of CYP1A2 activity. A possible mechanism by which the ratio might be influenced by NAT2 genotype is suggested.


A genetic algorithm is convergent when genetic mutations occur on the objective function gradient direction. These genetic mutations are called genetic acquisitions (Mateescu, 2005). We improved the algorithm and its implementation by using the characteristics of parents in order to generate new individuals. Finally, we applied the genetic algorithm in order to find the parameters of a Cobb-Douglas function.


This paper surveys recent progress in fiber spinning technology for reducing polarization mode dispersion with the focus on theoretical understanding of fiber spinning mechanism and features of spun fibers, as well as their applications in fiber spin profiles designs. First, a brief introduction to the requirements of fiber PMD for high-speed optical fiber communications systems is given. Further discussion covers several spin technologies, including preform spinning and fiber spinning. Different theoretical approaches for modeling fiber spinning are reviewed with the emphasis on the coupled-mode formalism. The coupled-mode theory is then applied to different fiber spin profile designs, including constant, sinusoidal and frequency and amplitude modulated spin profiles. Main features of these spin profiles, such as PMD reduction dependence on fiber beatlength and sensitivity to spin parameters, are compared. Scaling properties of spun fibers, which show different behaviors from unspun fibers, are also discussed.


BackgroundSeveral methods have been suggested for risk stratification of patients with unstable coronary syndromes. However, most of these are applied several days after hospital admission. MethodsIn this study we investigated the prognostic value of continuous ST-segment and QRS vector monitoring with computerized vectorcardiography (VCG), serial measurements of creatine kinase isoenzyme MB (CK-MB), predischarge stress testing and baseline data in patients with unstable angina pectoris or non-Q-wave infarction. ResultsDuring the 24 h VCG monitoring, 56 (29%) of the 195 patients had ST-vector magnitude (ST-VM) episodes of ischaemia. Seventy-four (38%) patients had a peak CK-MB value of 6 μg/I or higher during the 48 h sampling period. Several discrete variables were associated with death or non-fatal infarction at 1 year of follow-up in an univariate analysis. Among these were age ≥65 years, female sex, ST depression on the admission ECG or VCG monitoring, and elevated CK-MB levels, but neither the occurrence, duration nor intensity of chest pain. With Cox's proportional hazards regression analysis, ST-VM episodes on VCG monitoring were identified as independent markers of the risk of death (P=0.013), death or non-fatal infarction (P= 0.035) and death, non-fatal infarction, unstable angina during the first year, or revascularization before hospital discharge (P= 0.005). ConclusionsVCG monitoring of ischaemia provides independent prognostic information in unstable angina. High-risk patients can easily be identified within 24 h of hospital admission. Whether early intervention based on these criteria will result in improved prognosis remains to be shown in future studies.


This paper explains a Pelosika Dam Diversion Tunnel in metamorphic rocks (quartz muscovite phyllite) and aims to find out excavation methods, stand-up time, and support systems for tunnel construction. The purpose of this research is that the development of science in tunnel construction with the characteristic of metamorphic rock will increase. Tunnel location in poort rock mass quality based on previous geology investigations. Based on current geology and engineering geological mapping results, diversion tunnel through poor rock mass of metamorphic rocks (phyllite) which have slightly-highly weathered. We classified rock mass quality by GSI, RMR, and Q-System methods which produce the almost same results (poor rock mass quality). The GSI Chart and Pettifer-Fookes Chart which excavation method has the results of the digging and ripping. RMR value determines the stand-up time last 42-240 minutes after excavation. RMR and Q-System values generate the support system which used rock bolts (length= 1.8 m), shotcrete (thick=10-15 cm), and steel sets (spacing=1,5m) if required. A purpose of combination from the different excavation methods and support systems to complement each other and improve the safety of the tunnel without compromising the cost-effectiveness of construction.


The stress relaxation of poly(methyl acrylate)-poly(acrylonitrile) copolymer samples was carried out in air, distilled water, pH 3, 7 and 11 solutions at various temperatures using a tensile tester equipped with a solvent chamber. The relaxation spectra of poly(methyl acrylate)-poly(acrylonitrile) copolymers were obtained by applying the experimental stress relaxation curves to the equation of relaxation spectrum derived from the Ree-Eyring and Maxwell model. The determination of relaxation spectra was performed from computer calculation using a Laplace transform method. It was observed that the relaxation spectra of these samples are directly related to the distribution of molecular weights and self-diffusions of flow segments.


Unit cell models are used to study the densification by coinpressive mechanical loading of molybdenum containing initially spherical pores at volume fractions between 2% and 10%. The model geometries correspond to body centered cubic arrangements of voids in a matrix. The stress and strain fields in the cells are solved for by the Finite Element Method. The molybdenum matrix is described by an elastoplastic material model and contact between the pore surfaces is provided for. Densification up to very small residual porosities is modeled by the above continuum micromechanical approach for two levels of the overall stress triaxiality. The evolution of the shapes of the pores is found to be markedly influenced by the loading conditions and the pore geometries are predicted to differ markedly from ellipsoids at elevated degrees of densification.

This experiment was designed to investigate the effect of physiological data-based reproduction of musical performances in VR on affective states.


The pronouns σ ̓ in καί σ ̓ οὔτ ̓ ἀθανάτων φύξιμος οὐδείς (Soph. Ant. 787) and μ ̓ in εἰ δέ μ ̓ ὧδ ̓ ἀεὶ λόγους ἐξῆρχες (Soph. El. 556-557) have traditionally been analysed as accusative objects governed by a deverbal nominal and a verbal periphrasis. Both assumptions are mistaken. Scholars have been deceived by the spellings σ ̓ and μ ̓ which are suggestive of elision. In the passages at issue μ ̓ and σ ̓ stand for μοι and σοι. These datives are cogent from the viewpoint of both syntax and phonetics. Contrary to a widespread but unfounded belief, there is conclusive evidence that, although usually avoided, the crasis of μοι and σοι with word-initial ουand ωwas occasionally tolerated in Attic drama.
