The Hoover Dam Bypass project (US-93) crosses the Colorado River between Arizona and Nevada below Hoover Dam, 30 mi southeast of Las Vegas, Nevada. The Arizona approach to the river includes the seven-span, 900-ft long Sugarloaf Mountain Bridge. The east bridge abutment footing is supported on a welded-wire–reinforced, special embankment fill zone within a 130-ft high rockfill embankment. Reinforced zone backfill consists of 4-in. maximum size select granular backfill; the remainder of the embankment consists of 2-ft maximum size rock. Backfill and rockfill were obtained from project roadway cuts, and construction and acceptance of the reinforced zone and rockfill embankment were in accordance with FHWA standard specifications and project special provisions. Postconstruction settlement of the embankment was monitored for 2 years with conventional survey monuments on abutment wingwalls and the embankment and multipoint borehole extensometers (MPBX) in the roadway shoulders. The monitoring period included 3 months before placement of the closure span and deck. Roughly 1 in. of settlement beneath the reinforced fill was measured during construction, with an additional 1/2 in. of settlement within 2 years after fill placement. Postconstruction settlement of the wingwalls was approximately 1 in. The rate of settlement decreased through the 2-year period, and settlement from construction and self-weight is nearly complete. Use of the MPBX was deemed partially successful in this application.


Efforts to change dysfunctional social behaviour such as smoking and alcohol drinking-and-driving has been the focus of considerable research attention in attempts to prevent or at least reduce the occurrence and re-occurrence of dysfunctional behaviour. Despite these efforts, many questions remain. One of them is the effectiveness of fear-based appeals in social communication campaigns as years of research have still not produced conclusive evidence as to whether this communication approach is successful in modifying dysfunctional behaviour. One reason why the use of fear appeal effectiveness has been called into question is the defensive reactions that fearbased messages may arouse. To reduce the occurence of these defensive mechanisms, the use of a new fear appeal approach in social communication campaigns has been suggested, namely question-based warnings.The primary objective of this study was to investigate whether different fear appeal framing approaches (question-based vs statement-based framing) and gender would influence relatively young generation Y consumers' protection motivation differently when exposed to an anti-drinking-and-driving campaign. The results revealed that statement-based warnings evoked greater feelings of vulnerability, self-efficacy perceptions and behavioural intent amongst females than question-based warnings. In the case of the males, however, the type of fear appeal approach used is inconsequential as different fear appeal approaches do not influence their protection motivation responses differently.


Although intramuscular neostigmine methylsulfate is frequently used during diagnosis or initial therapy in patients with myasthenia gravis, little is known of its metabolism and excretion in these circumstances. The kinetics and disposition of neostigmine methylsulfate ( 1 .O-2.0 mg intramuscularly) was therefore studied in eight myasthenic patients who had a history of voluntary muscle fatiguability for a period of two months to two years. In most subjects, characteristic electromyographic changes were observed and a positive response to edrophonium chloride ("Tensilon") was obtained. None of the patients were currently taking other compounds or were on anticholinesterase drugs. Studies of the plasma concentration of neostigmine were carried out in five myasthenic patients after intramuscular injection of the drug (2.0 mg). In two subjects, neostigmine was detected in plasma within 15 min. In all five patients, the plasma concentration invariably declined in a monoexponential manner from 21 k 2 ng/ml (mean f S.E.M.) to 9 k 1 ng/ml (mean +S.E.M.) between 30 and 120 min. Small concentrations of neostigmine (5-7 ng/ml) were present in plasma at 150 min in three subjects; in one instance, the drug was stilI detectable at 180 rnin. None of the quaternary amine could be detected in plasma in any of the five patients at 240 min. In other myasthenic patients, the elimination of the drug and its metabolites in urine was studied after intramuscular administration of 14C-neostigmine (1.0 or 2.0 mg neostigmine methylsulfate containing 1.5 pCi of I4C-neostigmine). Unchanged neostigmine and its principal identified metabolites (i.e., 3-hydroxyphenyltrimethylammonium and its 3-oxyglucuronide) were isolated from urine, and identified by both ion exchange and paper chromatography. Approximately 80% of the drug was excreted in urine, either as unchanged neostigmine or its metabolites, within 24 hours. At this time, roughly 50% of the dose was eliminated as the unchanged drug, 15% as 3-hydroxyphenyltrimethylammonium, and 15% as other unidentified metabolites. The decline in the concentration of neostigmine in plasma and urine was interpreted in terms of a one compartment open pharmacokinetic model. Estimates of the plasma half-life of neostigmine varied from 51.1-90.5 min,


ABSTRACT This paper is dedicated to the imitation of breaking waves in a coastal zone (the zone where wave height is comparablewith the depth). The method proposed is aimed at virtual reality applications. It should imitate quite complicated proc-esses of wave transformation, destruction and further propagation; splashes and foam phenomena. At the same time, ithas to satisfy computer performance restrictions in real time applications. The paper describes the method of 3D waveshape reconstruction based on 2D profiles, modification to the simulation method in 2D that allows continuing simula-tion after wave breaking and proposes an algorithm of splashes and foam imitation. The result of this method — real-timesimulation of complex phenomenon of breaking wave. The paper contains the algorithm description, performance meas-urements of its software implementation and 3D waves screenshots.Keywords: coastal zone, virtual reality, water simulation. 1. INTRODUCTION In paper' we presented the methods for simulation of breaking wave in coastal zone in 2D. Those methods can be self-sufficient but our real aim is 3D modeling. In' we pointed the ideas how to use the results of our methods to get 3D pic-ture in real-time. The present paper describes methods that was grown from those ideas and presents practical results. Inother words we introduce method for generating 3D picture ofbreaking waves from the set ofprecalculated 2D profiles.We want to use our technology in real-time applications that need breaking waves imitation. Thus we do not want to belimited by one wave in the scene. We need a possibility to display the scene with waves coming from the open sea, trans-forming, breaking and flooding the shore.The basic idea is rather simple: at the preprocess stage we should rebuild profiles to make them loopable, and then,per frame, we should take profiles at different phases (depending on the bottom), then triangulate them into grid, imitatesplashing and foam effects. But the problems are hiding in details.

To enable growers and provide consumers with Phaseolus lunatus (L.) seeds of good nutritional quality, this study was carried out on Phaseolus lunatus seeds obtained from pods of white, red and black cultivars harvested at stage 1 (32 days), stage 2 (38 days), stage 3 (45 days) and stage 4 (52 days) after fertilisation. Weight of pods and seeds at harvest decreases from stage 1 to stage 4 of maturity. Major biochemical compounds such as crude protein, carbohydrates and lipids of seeds are highest at stage 4 (52 days) of maturity. Seeds of the black cultivar are richer in protein, with a content varying between 17.51 ± 0.17 and 21.21 ± 0.18 % at stage 4 (52 days) of maturity. Seeds of black cultivar produced at stage 4 (52 days) are rich in vitamins B1, B2, B6 and B9 and antioxidants such as carotenoids and flavonoids. These seeds contain high levels of vitamins B6 (pyridoxine) and B9 (folic acid). The concentrations of these vitamins vary from 1900 to 2000.03 μg/100g of dry matter and from 599.93 ± 0.86 to 600 ± 1.00 μg/100g of dry matter respectively. P. lunatus seeds obtained at stage 4 (52 days) were rich in minerals. The Na/K ratio of white, red and black bean seeds varies from 0.04 to 0.05, i

Abstract Aims Due to its bidimensional nature, angiography is not always sufficient to accurately define coronary lesions, in particular when they are ambiguous or indeterminate. Intracoronary imaging, such as intravascular ultrasound or optical coherence tomography (OCT), is often useful in these cases to better characterize the ambiguous angiographic images, to identify the culprit lesion during acute coronary syndrome (ACS) and to guide percutaneous coronary intervention (PCI). Methods and results We report a case of a 61-year-old male with multiple cardiovascular risk factors and a previous ST-segment elevation myocardial infarction treated by PCI of the right coronary artery (RCA) about 7 years before, wo was admitted to our emergency department after acute onset chest pain. At the time of admission, his ECG was normal and cardiac troponin was below the upper reference limit of normality with positive molecular SARS-CoV-2 diagnostic test. Echocardiogram disclosed a mild left ventricular dysfunction with inferior wall hypokinesia. Coronary angiography showed a moderate in-stent restenosis at mid RCA and a hazy, undetermined image at the proximal edge of the previously implanted stent. Left coronary artery angiography showed only diffuse atherosclerotic disease without significant stenoses and a myocardial bridge at the mid tract of left anterior descending artery. OCT pullback of RCA to better characterize the undetermined lesions shown by angiography. OCT revealed significant neointima hyperplasia and a focal area of neoatherosclerosis with unstable features (fissure/microthrombi) at mid RCA. Severe stent strut malapposition embedded neointimal hyperplasia was observed at the proximal stent edge, resulting in 'dual' lumen appearance. The two lesions were treated with a single 3.5/48 mm everolimus-eluting stent (stent-in-stent), which was post-dilated with a 3.5/20 mm non-compliant balloon (18 atm) in the mid-to-distal segments, and 4.5/15 mm (16 atm) and 5.0/8 mm (14 atm) semi-compliant balloons in the proximal stent segment. Post-PCI OCT imaging confirmed good stent expansion and apposition. Our case demonstrates the utility of OCT in clarifying the aetiology of ambiguous angiographic lesions and as a guide for PCI. Indeed, the 'hazy' appearance on the angiograms corresponded to the major stent malapposition covered by neointima disclosed by OCT as a 'dual-lumen'. Of note, OCT allowed to confirm the correct guidewire position in the 'true' lumen preventing a crush of the previously implanted stent. OCT was also useful as a diagnostic modality for the identification and characterization of the mechanism underlying the ACS (neoatherosclerosis instability). Conclusions Due to its unprecedented spatial resolution, OCT enables an 'optical biopsy' of the coronary artery wall and intrastent tissue. Therefore, OCT imaging should be considered when lesions are ambiguous or indetermined by coronary angiography to guide the diagnosis and treatments of ACS patients. OCT imaging is also useful to guide stenting and to optimize PCI result, and its impact on clinical outcome is under investigation in large randomized clinical trials.


This essay concerns the labors of Catholics in the mid seventheenth-century English settlement at St. Mary's in Mary land and their ideas concerning the establishment of religious freedom. To a certain degree it also concerns the Catholics in England. The essay raises the possibility that the Catholics in Maryland narrowed the separation between church and state to advance what they believed was their religious freedom. At the same time in England, the laboring people may have widened the separation between church and state to achieve the same goal. Part of the discussion centers on why laboring Catholics took one path to religious freedom in Maryland and another in England. The traditional historical interpretation of the Maryland community during the period emphasizes the role of the 1649 Act of Religious Toleration, which in a sense widened the sepa ration between church and state to protect the Catholics' free dom.1 However, the focus of this essay is on a series of laws enacted soon after settlement which narrowed the separation between church and state. These laws preceded the 1649 Act by a decade. The earlier laws addressed a threat to the


The optical absorption and fluorescence spectra of trivalent thulium in single crystals of yttrium oxide and the absorption spectrum of pure thulium oxide, are investigated. All the 4f12 electronic energy levels except the 1S0 level are identified. The three Slater Fk parameters and the spin—orbit parameter ζ, giving the best over‐all agreement between the observed spectrum and the calculated spectrum are: F2=446.70 cm—1, F4=70.491 cm—1, F6=7.534 cm—1, and ζ=2617 cm—1. A detailed crystalline‐field splitting perturbation calculation is carried out for trivalent thulium and trivalent erbium ions in the C2 sites of the Y2O3 lattice. The predicted crystalline‐field splitting for these ions is compared with the thulium data reported in this paper and with the erbium data reported earlier. The average deviations between the predicted and the observed splittings for 71 crystalline Stark levels in the Tm3+ spectrum and 65 levels in the Er3+ spectrum, are 13 and 11 cm—1, respectively.


Organophosphate compounds and carbamates are commonly used as insecticides in the agriculture and as petroleum additives, flame retardants and lubricants in industry. Organophosphate and carbamate poisoning can present as acute cholinergic crisis, intermediate syndrome or delayed neuropathy. Carbamates are reversibile inhibitors of acetylcholinesterases, and some also inhibit neuropathy target esterases (NTE), the target in organophosphate induced delayed neuropathy. Though carbamates are widely used, they are thought to be unable to initiate delayed neuropathy due to mechanistic considerations. Hence carbamate induced delayed neuropathy is only rarely reported in literature. We report a patient with carbamate poisoning, who had classic acute cholinergic crisis with subsequent development of delayed neuropathy. No definite treatment is available for delayed neuropathy and recovery is poor. We conclude that though it is rare, all patients with carbamate poisoning should be followed up for atleast four weeks for early identification of intermediate syndrome and delayed neuropathy.

In this study, sStrain SK‐1T, a novel gram‐positive, pleomorphic, rod‐shaped, non‐spore forming, non‐motile organism, designated SK‐1T, was isolated from human gingival sulcus and found to produce acetic acid, propionic acid, lactic acid, and succinic acid as end products of glucose fermentation. Strain SK‐1T is most closely related to Pseudopropionibacterium (Propionibacterium) propionicum with sequence homologies of the 16S rRNA and RNA polymerase β subunit (rpoB) genes of 96.6% and 93.1%, respectively. The genomic DNA G + C content of the isolate was 61.8 mol%. On the basis of the sequence data of the 16S rRNA and housekeeping (rpoB) genes, a novel taxon is here proposed, Pseudopropionibacterium rubrum sp. nov. (type strain SK‐1T = JCM 31317T = DSM 100122T). The 16S rRNA and rpoB gene sequences of strain SK‐1T have been deposited in the DDBJ under the accession numbers LC002971 and LC102236, respectively.

We propose a software development method for enterprise applications that combines the use of the structural concepts provided by the Michael Jackson's problem frames, and the use of the UML notation, within an MDA approach. Problem frames are patterns that provide a precise conceptual model of what is the problem to be solved. The first step of our method is to match the current development task with the problem frame that we propose for entreprise applications, and this helps to understand the nature of the problem under study. For each problem frame, a diagram is settled, showing the involved domains, the requirements, the design, and their interfaces. Being within an overall MDA approach, each part of the problem frame will be described by a (UML) model of the appropriate kind (computation independent, platform independent, and platform dependent, depending on the development phase). We then provide guidelines to develop all the models required by the method through a dedicated choice of appropriate UML diagrams together with predefined schemas or skeletons for their contents. Thus, using our method provides a more direct path to the UML models, which saves time (no long questions about which kind of models, and of diagrams to use and how) and improves the models quality (relevant issues are addressed, a uniform style is offered). In this paper, we consider the phases of modelling the domain, the requirements capture and specification, and their relationships, resulting in two computation independent models.


have felt less at risk when seated with members of their own group. Limitations of the study include generalizability to other large indoor gatherings. This study occurred before widespread vaccination availability, and many COVID-19 restrictions were in place owing to high community spread. However, it provides insight on masking behavior at a mass indoor event similar to other large indoor gatherings that have the potential to become superspreader events.4 When vaccinations are not available or coverage is low, ensuring adherence to key transmission mitigation strategies such as mask wearing during mass events is critical during the current, and any future, pandemic.


A review is made of the injuries occurring after x-ray therapy, with special consideration of late injury, Means and methods for avoiding injury in therapeutic x-ray treatment were also discussed. Some methods of x-ray therapy, as, for example, radiocastration, have the purpose of deliberate damage to an organ and can be carried out without damage to the total organism. X-ray therapy, under professional conditions and precise site location, can be performed without damage to the genetic structure. (tr-auth)


AN ACCIDENT ANALYSIS WAS CONDUCTED TO MEASURE THE RELATIONSHIP OR ASSOCIATION THAT EXISTS BETWEEN ACCIDENTS AND HIGHWAY DESIGN AND ROADSIDE FEATURES. A 70-MILE STRIP OF ROAD CALLED TELEGRAPH ROAD WAS SELECTED FOR THE ANALYSIS. STATISTICAL ANALYSIS OF THE DATA OBTAINED WERE PROCEEDED BY TWO METHODS. ONE TABULATED FREQUENCY DISTRIBUTIONS OF ACCIDENTS BY DISTANCE OF OCCURENCE FROM EACH SPECIFIC FEATURE. FROM THESE DISTRIBUTIONS CUMULATIVE PERCENTAGES WITHIN VARIOUS DISTANCES AND RATE CURVES WERE COMPUTED. THE OTHER APPROACH CALCULATED CORRELATION COEFFICIENTS BETWEEN THE NUMBER OF ACCIDENTS AND THE NUMBER OF VARIOUS ROADSIDE AND DESIGN FEATURES. A DETAILED ANALYSIS IS PRESENTED OF CONCLUSIONS OBTAINED FROM THE TWO STATISTICAL TECHNIQUES EMPOYED. INTERSECTIONS LEAD ALL OTHER FEATURES WITH 55% OF THE ACCIDENTS OCCURRING AT THE FEATURE AND BY THE CRITERION OF THE CUMULATIVE PERCENTAGE INTERSECTIONS ARE DEFINITELY THE MOST HAZARDOUS FEATURE IN THE STUDY. GAS STATIONS ARE NEXT WITH 38% OF THE ACCIDENTS OCCURRING AT ZERO DISTANCE AND THE DISTRIBUTION PATTERN IS SIMILAR TO THAT FOR INTERSECTIONS.


Ela Bhatt, the founder of the first trade union for women, the Self Employed Women's Association (SEWA), has reached legendary heights in India and many parts of the world. This book documents her experiences as a trade unionist and social activist. It is an important document as it details how she helped in organizing the union, and the trials and tribulations she faced in achieving this. SEWA as a union is unique because it includes both unions and cooperatives. Bhatt notes, "The union mobilizes and organizes the women to come together around their work issues. The women then form trade cooperatives in an effort to become owners of their labour." (p. 16). This is perhaps the most effective way of organizing workers in the unorganized sector.


The LD50 of Nippostrongylus muris for outbred hooded rats has been estimated. It was higher for males than for females and this does not appear to be due to weight differences. The distribution of times of death was bimodal; the peaks corresponding to different stages in the life cycle of the worm. We wish to thank Mrs M. Whitehead for technical assistance and Mr I. McDonald for statistical analysis.


Abstract:In order to address the research gaps on climate finance dynamics in developing countries, especially those with low governance scores, this study assesses the 2016–2020 bilateral climate finance to these countries. The total disbursed bilateral climate finance was US$1.3 billion (92 percent for mitigation, 7 percent for adaptation, and 1 percent for mitigation and adaptation simultaneously). Development-focused loans were the prevailing financial instrument cumulatively, and grants were the prevailing instrument on a per-country level. Japan was the biggest provider of bilateral climate finance (US$1 billion) to fund Uzbekistan's natural gas-fired electric power plants. All major bilateral climate finance providers ranked high on governance scores compared to the ten examined countries. Countries examined in this study will need to receive higher amounts of bilateral climate change finance in order to improve their readiness to address this issue and reduce their vulnerability to climate change impacts.

Present paper deals with in vitro callus induction in two medicinal plants Tribulus terrestris L. and Pedalium murex L. from leaf explant cultured on MS medium supplemented with 2,4-D (0.5, 1.0, 2.0 mgl−1), BAP (0.5,1.0,2.0 mgl−1) and Kin ((0.5,1.0,2.0 mgl−1). 2,4-D (2.0 mg/l−1) exhibited 61.83% callus formation with leaf explants of T. terrestris while 52.30% with P. murex. Total alkaloids, flavonoids and phenolic contents of the leaf tissues were 1.8 times higher than that in the callus of T. terrestris. In case of P. murex it was 2.5 times higher.


Knowledge about the demographic and environmental factors underlying population dynamics is fundamental to designing effective conservation measures to recover depleted wildlife populations. However, sparse monitoring data or persistent knowledge gaps about threats make it difficult to identify the drivers of population dynamics. In situations where small, declining, or depleted populations show continued evidence of decline for unknown reasons, integrated population models can make efficient use of available data to improve our understanding of demography, provide fundamental insights into factors that may be limiting recovery, and support conservation decisions. We used mark‐resight and aerial survey data from 2004 to 2018 to build a Bayesian integrated population model for the Cook Inlet population of beluga whales (Delphinapterus leucas), which is listed as endangered under the U.S. Endangered Species Act. We examined the effects of prey availability and oceanographic conditions on beluga vital rates and conducted a population viability analysis to predict extinction risk across a range of hypothetical changes in beluga survival and reproduction. Our results indicated that while the survival of breeding females (0.97; 95% CI: 0.95–0.99) and young calves (0.92; 0.80–0.98) was relatively high, the survival of nonbreeders (0.94; 0.91–0.97) and fecundity (0.28; 0.22–0.36) may be depressed. Furthermore, our analysis indicates that the population will likely continue to decline, with a 17–32% probability of extinction in 150 years. Our model highlights the utility of integrated population modeling for maximizing the usefulness of available data and identifying factors contributing to the failure of protected populations to recover. This framework can be used to evaluate proposed conservation and recovery efforts for this and other endangered species.


In the aftermath of the 2008 crisis, corporations in emerging market economies increased their issuance of debt securities in international financial markets under significantly better conditions. The undergoing process of normalization of monetary conditions, particularly in the U.S., poses potentially significant risks for these firms, especially as U.S. interest rates increase and exchange rates in emerging economies depreciate. This paper has two main objectives: (1) to describe the recent evolution of corporate financing in Mexico and quantify the potential adverse effects on foreign corporate debt servicing to interest rate and exchange rate shocks; and (2) to assess how changes in global liquidity may affect both the ability of large Mexican corporates to tap international financial markets and the access of large and small and medium enterprises (SMEs) to domestic credit. The analysis uses a novel data set that combines credit-level data of the universe of all loans and lines of credit granted by banks and non-banks to non-financial private firms in the country, the universe of all bond placements by these same companies, and balance sheet information of bond issuing firms between 2003 and 2014. Our results suggest that the increase in global liquidity in the years following the Great Crisis significantly reduced international borrowing costs for large debt-issuing firms in Mexico, which in turn explains the rise in foreign debt placements in recent years. We illustrate that, as large firms have turned away from domestic financing sources, commercial banks in Mexico have been able to funnel more resources to SMEs–a situation that may potentially reverse once international credit conditions become more restrictive and large firms return to domestic lending markets.

Studies show that residents from urban, high-risk neighborhoods fair worse on multiple behavioral and health outcomes than their counterparts from more socially and economically advantaged neighborhoods. However, few research efforts have been devoted to examining how formerly incarcerated individuals' concerns over neighborhood environment are associated with reentry outcomes. Using longitudinal data that captured the reentry experiences of individuals released from prison, the present study quantifies how returning citizens' concerns over neighborhood environment predict their social withdrawal and mental health deterioration. Findings suggest that when respondents' post-release family bonds, financial difficulty, drug use, and past mental health histories are all taken into account, their concerns over neighborhood environment exert a significant and positive effect on social withdrawal, depression, and hostility. Returning citizens who believe it is hard to stay out of trouble and prison in their neighborhoods tend to avoid social interactions with others and experience depression and increased hostility and vigilance. Implications for reentry programing and interventions are discussed.


Current authentication practices suffer from many loopholes. To access an online banking facility, a customer with Internet access would need to register with the institution for the service, and set up some password for authentication process. Basically there are two types of password inputs allowed by banking websites these days. The first one is the traditional input in which we enter the password using keyboards and the second one is the virtual input in which the system accepts password using a virtual keyboard available in login pages of all bank websites. Virtual keyboards are considered as additional security steps for accessing online banking websites but this paper will describe how weak this implementation can be and what security measures can be adopted to maintain the confidentiality.

The dynamics of the Local Group is investigated using the virial theorem in detail, with various assumptions about the orbits and the binding of subgroups. It is concluded that the Local Group is stable against disruption without the assumption of "missing mass.


Reglet means, counterflashing, and connector and biasing means are provided having the reglet means adapted to be secured to a building wall to afford flashing above a roofing end reaching upwardly and lapping the wall. The reglet means includes hood structure which receives shaped upper end means of the counterflashing while apron means of the hood structure, and the connector and biasing means, are interrelated so that with the connector and biasing means being inserted into the hood structure from below, with bight means of the connector and biasing means leading, first presser means of the connector and biasing means and means on the apron means engage for stopping the connector and biasing means against being retracted from the hood structure, and second presser means of the connector and biasing means acts against the counterflashing for the latter to cover and urge the roofing end to be supported against the building wall while the connector and biasing means arrests the shaped upper end means of the counterflashing against downward movement from the hood structure.


Chain sprocket is one of the most important parts used in transmitting power from the engine to the drive shafts. This study mainly deals with the design and analysis of rear sprocket of a Formula Student car. This sprocket is designed such that it is light in weight and functions efficiently with the KTM Duke 390 engine. The type of chain used is roller type chain. The main challenge faced is determining the proper material and number of teeth for chain sprocket. Many iterations were carried mathematically to determine the total number of teeth and final drive ratio. The CAD model was created in SolidWorks and Finite Element Analysis was carried out in ANSYS Static Structural module. Initially a solid sprocket was created without any slots for different materials and Static structural analysis was performed. For doing static analysis, the forces and torques acting on the teeth of sprocket were calculated. Boundary conditions were applied such that the bolt ends were made to be fixed and parameters like tensile force, torque were applied at the sprocket teeth that were engaged during the operation. By observing the stress distribution in the solid sprocket, slots were created, in order to reduce the overall mass of the sprocket. Various CAD models were created in SolidWorks and were analyzed in ANSYS by applying static loads and assigning different materials. The best material and optimal design was selected based on the mass property and results obtained from ANSYS.

through the bronchial blocker tube lumen (Fig. 1). The CPAP device was connected to the bronchial blocker tube via an endotracheal tube connector having an inner diameter of 3.0 mm. The distal part of the 15-mm tube connector was snugly fitted to the proximal lumen of the bronchial blocker tube. The CPAP dial was set at 5 cm H2O with an O2 flow rate of 5 L/min. The initial Pao2 value, Pao2 values before and during CPAP application were 122.1, 64.2, and 125.5 mm Hg, respectively. There have been some previous reports (1,2) about administering CPAP with a Univent tube. The previously proposed techniques did not permit checking the amount of CPAP applied to the lung. The device shown in Figure 1 delivers CPAP at a lower pressure than that marked on the device, at the designed fresh gas-flow rate of 5 L/min, enhancing safety.


The beef tapeworm (Taenia saginata) and the pork tapeworm (T. solium) are the two most common forms of taeniae found in the Boston area. We have had no experience with the use of the method described in this report in the treatment of the fish tapeworm (Diphyllobothrium latum) or of the dwarf tapeworm (Hymenolepis nana). Man is the primary host for all of these parasites, and in all but the dwarf tapeworm one or more intermediate hosts are necessary for the full life cycle to take place. 1 The adult taeniae live in the small intestine of man, their heads attached to the mucosa of the duodenum or jejunum. 2 They have no digestive tracts but absorb food through their body walls. The body of the worm, which may be as long as 15 ft., is made up of numerous segments each of which discharges ova from an oviduct. When


The main task discussed in this publication was to prepare a laboratory stand to investigate the confidentiality of information processed. The first part of the article presents a comparison of the possibilities of two open license programs - encryption tools that implement encryption with the use of AES block cipher. The second part describes the operation of two programs created in C++ for the needs of the laboratory workstation. The first one performs classic, changeable encryption, the second one uses XOR operation for encryption.


VTIS is a dynamic notification system that takes in a user's route and calculates the time-delay imposed by disruptions to the normal traversal. The disruptions are calculated by using crowdsourced notifications. This is accomplished by the creation of a client side application for notification display and a server infrastructure that will process and store the event information. We have devised a system that will generate personalized notifications for users based on a provided path, temporal range, and set of transportation modes. At a high level, the functionality of this system is to identify events that affect the user's route and notify the user of these events. The VTIS will provide a multimodal notification system based on information mined from Twitter data and volunteered information from VTIS users. This information will be stored to create a repository of transportation events., This repository will be queried to notify affected users of events that may affect their route.. Although this outlined problem has been solved previously, our approach is novel in several ways: (1)accounting for multiple modes, (2)combining user input with mined data, and the (3)modeling method used to calculate effects on the user's route. Some of these methods have been implemented separately; however, a comprehensive system has not been constructed that includes all of these items.


Concentration and effective temperature of carriers are established to compete in their influences on the band‐edge dielectric function of an active semiconductor medium under the lasing conditions. This competition is shown as capable of suppressing the relaxation oscillations and wavelength chirping in the modulation response of a semiconductor laser, provided the carrier injection and carrier heating are combined in a suitable way. The problem of how to combine them is studied under the small‐signal approximation assuming that modulation signal can be imposed on both the injection current and energy flux flowing into the active layer. All the numerical results relate to single‐frequency 1.55 μm GaInAsP/InP laser.

The vigorous development of big data technology has changed the traditional user requirement acquisition mode of the manufacturing industry. Based on data mining, manufacturing enterprises have the innovation ability to respond quickly to market changes and user requirements. However, in the stage of complex product innovation design, a large amount of design data has not been effectively used, and there are some problems of low efficiency and lack of objectivity of user survey. Therefore, this paper proposes an acquisition method of user requirements based on patent data mining. By constructing a patent data knowledge base, this method combines the Latent Dirichlet Allocation topic model and a K-means algorithm to cluster patent text data to realize the mining of key functional requirements of products. Then, the importance of demand is determined by rough set theory, and the rationality of demand is verified by user importance performance analysis. In this paper, the proposed method is explained and verified by mining the machine tool patent data in CNKI. The results show that this method can effectively improve the efficiency and accuracy of user requirements acquisition, expand the innovative design approach of existing machine tool products, and be applied to other complex product fields with strong versatility.


Two novel photochromic dithienylethenes, [1-(2-methyl-5-p- methylphenyl-thien-3-yl)-2-(2-methyl-5(4-(1,3-dioxolane) phenyl)- thien-3-yl)]perfluorocyclopentene (DTE-1) and [1-(2-methyl-5-(3- thienyl)-thien-3-yl)-2-(2-methyl-5(4-(1,3- dioxolane)phenyl)-thien-3-yl)]perfluorocyclopentene (DTE-2), were synthesized and their photochemical properties, such as photochromism and fluorescence were investigated. DTE-1 and DTE-2 have shown good photochromic behavior. Upon irradiation with 254 nm UV light, their color changed from colorless to blue, in which absorption maxima were observed at 590 nm and 592 nm in CH2Cl2. DTE-1 and DTE-2 also showed relatively strong fluorescence in different solvents when excited at 295 nm. While, their fluorescence spectra showed remarkable concentration dependence. In addition, near-field recording using DTE-1 as recording medium was performed successfully.

ACRA consisted of a useful instrument for the development of the master's student's project concerning patients' health education as well as knowledge building regarding the researched theme. The patients were benefited with a better understanding of their problems and the discovery of healthy ways to deal with their diabetes condition. It also contributed for the theoretical knowledge development regarding the patients' manners of taking care of themselves as well as preventing related complications to diabetes.


Aseries of computer programs was developed using an existing data base management system (KnowledgeMan) on a microcomputer to assist with the management of a diagnostic virology lab. The primary purpose was to handle the daily routine: recording specimens and patient data, generating worksheets for the reading and processing of cultures, retrieving culture results or current status, and printing final report forms. It can also handle other lab procedures: Chlamydia cultures, Clostridium difficile toxin assays, and some serologic testing. In addition, the computer facilitates surveillance studies. It can rapidly generate a list of cultures or results for user-defined conditions: ages, hospital location, dates, or a variety of other parameters. A statistics package is included for simple analyses. Security of patient data is always a concern with computer use because of the ease of transporting large volumes of information on floppy disks. Security is provided by KnowledgeMan. All information is stored in scrambled form within files, and cannot be read if accessed from outside KnowledgeMan. On entering the system, each user is assigned a priority status. Each data type, e.g. name, age, result, is assigned up to 16 different access codes to restrict the user to certain pieces of information. The series of programs is menu-driven, and requires no computer knowledge by lab personnel. A computer can decrease significantly the paperwork done by hand, file large amounts of information in a small space, facilitate epidemiologic surveys, and provide a rapid review and analysis of the work performed by the laboratory.


There is interest of observe approximately implementation of Just-in-time (JIT) and Total Quality Management (TQM) for enterprise improvement. There are many corporations put in force JIT and TQM ideas in numerous distinction ways. Some of corporation may also pick to begin with TQM practices to be able to enhance nice of product and carrier via the corporation. Some of corporation may also pick to begin with implementation of JIT practices for disposing of waste and maximizing usage of stock and resources. The separate influences of JIT and TQM practices on enterprise overall performance have been analyzed and mentioned in lots of research. In 1990s, a few research attempted to discover the joint impact of each implementation of JIT and TQM on overall performance. Those research talked about the obtrusive that joint implementation of JIT and TQM ended in tremendous better overall performance than implementation of both one.


This book, sub-titled Nimitz, Halsey, Leahy and King - The Five-Star Admirals Who Won the War at Sea - is a major work deserving of a place in the library of anyone interested in the causes of and developments during World War II. It's drawback from the perspective of a British reader is that it was written by an American and concentrates almost exclusively on the war against Japan.


s—Teamwork and collaborative practice are necessary tools in handling health problems and the importance of interprofessional teamwork is becoming increasingly recognized. The process of team development is a series of multilevel, overlapping responsibilities, which are intertwined with each other, and disruption of team development process will lead to conflict. This study analyzed the pattern of intragroup conflict and group process in an interprofessional team. The study was conducted at the State Islamic University (UIN), Jakarta, Indonesia from February to October 2012 and involved 62 students (77.5% of total sample) from four disciplines (medicine, nursing, pharmacist and public health). They engaged in an interprofessional learning for community-based health care (COMIC program). Following their participation in this program, a positive result was achieved of improved group process (factors of trust, mutual respect, and open discussion) with significant statistical impact on the improvement of intragroup conflict (conflict of relationship, task and process) over time. This research produced a unique pattern of intragroup conflict and group process for each discipline. Keywords— intragroup conflict; group performance; interprofessional teamwork; collaborative practice


The mission of the DOE's Fuel Cell Technologies'™Hydrogen Fuels R&D effort is to research, develop, and validate technologies for producing, storing, and delivering hydrogen in an efficient, clean, safe, reliable, and affordable manner. A key program technical milestone for hydrogen technology readiness is to produce hydrogen from diverse, domestic resources at $2.00-$3.00 per gallon of gasoline equivalent (gge) delivered, untaxed. Low-cost, high-temperature hydrogen separation membranes represent a key enabling technology for small-scale distributed hydrogen production units. Availability of such membranes with high selectivity and high permeability for hydrogen will allow their integration with hydrocarbon reforming and water gas shift reactions, potentially reducing the cost of hydrogen produced. Pd-metal-based dense membranes are known for their excellent hydrogen selectivity and permeability characteristics, however, utilization of these membranes has so far been limited to small scale niche markets for hydrogen purification primarily due to the relatively high cost of Pd-alloy tubes compared to pressure swing adsorption (PSA) units. This project was aimed at development of thin-film Pd-alloy membranes deposited on Pall Corporation's DOE-based AccuSep® porous metal tube substrates to form a composite hydrogen separation membrane for these applications. Pall's composite membrane development addressed the typical limitations of composite structures by developing robust membranesmore » capable of withstanding thermal and mechanical stresses resulting from high temperature (400C), high pressure (400 psi steam methane reformer and 1000 psi coal) operations and thermal cycling involved in conventional hydrogen production. In addition, the Pd-alloy membrane composition was optimized to be able to offer the most stability in the typical synthesis gas environments produced by reforming of natural gas and bio-derived liquid fuels (BILI) validating the technical effectiveness and economic feasibility of the technology demonstrated. Results from this research added technology and product design information that offers the potential to significantly advance the commercial viability of hydrogen production.« less


In order to evaluate alternative genetic models to the additive dominant model, weights at yearling (PS) of 35,931 animals, sired by 752 bulls and 30,535 cows of Aberdeen Angus (A) and Nellore (N) breeds and the genetic groups from their crosses were used. Five different genetic models (M) were tested: M1, containing the direct additive fixed genetic effect (DA), heterozygote direct (HD), epystatic direct (ED), and direct joint additive direct (DJA); M2 was equal to M1, excluding DJA effect; M3 was equal to M1, excluding ED effect; M4 was equal M1, excluding ED and ACD effects, and M5 was equal to M1, excluding HD, ED, and DJA effects. The models were analyzed by different methods: Least Square Means Method (MQM), Ridge Regression Method (RC), and Restricted Maximum Likelihood Method (REML). Estimated coefficients by RC showed magnitude and sign which were biologically explained. The


Dispersive Liquid-Liquid MicroExtraction technique based on Solidification of a Floating Organic drop (DLLME-SFO) combined with flame atomic absorption spectrometry was developed for determination of thallium in water sample. An appropriate mixture of acetone and 1-undecanol was rapidly injected into an aqueous sample containing TlCl 4 - which forms an ion pair with brilliant green reagent and as a result a cloudy mixture was formed. After centrifugation, the test tube was cooled for 5 min and the solidified 1-undecanol drop formed on the top of the solution was transferred into a suitable vial and it was dissolved in 300µL of acetone and finally introduced into the flame atomic absorption spectrometer. Several factors affecting the extraction process, such as the volume of the extractant and disperser solvents, centrifugation time, concentration of brilliant green, concentration of HCl, ionic strength, volume of diluting solvent and interferences were studied. Under the optimum operating conditions, the calibration graph was linear in the range of 240-6000ng/mL with a limit of detection of 90 ng/mL and preconcentration factor was 17. The Relative Standard Deviation (RSD) for five replicate measurements of thallium was 3.6%. The accuracy of the method was assessed using a certified reference material (unalloyed zinc) and spiked tap water. The results demonstrated high accuracy, recovery and applicability of the presented method.


It was shown that stable surface films of nonpolar substances could often be formed on water by mixing them with stearic acid, and that in the resulting mixed films the nonpolar substance existed in the state of rather stable unit of particles, forming monoparticle films. The dimension of the surface particles could be calculated for some nonpolar substances. The mechanism of the film-stabilizing action of stearic acid was discussed and it was suggested that the different film-stabilizing substances would stabilize the film of nonopolar substance in a different manner.


Sebelas Maret University (UNS) as a member of a consortium for developing national electric vehicle (Mobil Listrik Nasional, in sort Molina). It is currently making a prototype electric vehicle. A battery is a major component in an electric vehicle and a supplier of energy to the Electric Vehicle (EV). Sebelas Maret University created a technology that was developed in the prototype Li-ion batteries based on LiFePO4 nanoparticles used for the application of the SmarT EV. Seeing the demand for lithium batteries continue to rise and the absence of lithium battery cell manufacturers in the country, the opportunities for commercialization of lithium ion battery cell production is very wide open. The new technology evaluated using the technology readiness levels (TRLs) and the Demand Readiness Levels (DRLs) which is developed in several alternative models of commercialization and the existing alternative generated by a decision matrix that is filled from in-depth interviews. This paper recommended for choosing a spin-off company as the best commercialization model of new technology lithium ion battery for Sebelas Maret University.


In this work, the authors present a new method to determine the particle size distribution of nickel-supported catalysts, based on the analysis of magnetic properties beyond the superparamagnetic approximation. Field-cooled magnetization curves of Ni supported on CeO/sub 2/ reduced under hydrogen at two different temperatures (250 and 400/degrees/C) have been measured for T < 620 K. Below 500 K, a progressive spin freezing of nickel particles is evidenced by the observation of a remanent magnetization and a deviation of the magnetic susceptibility from the Curie-Weiss law. They show that the blocking of the nickel particles is due to a strong strain anisotropy (3 /times/ 10/sup 6/ erg cm/sup /minus/3/) and that the two samples differ by the particle size distribution, although the mean size d is about the same (7.8 nm). They conclude that the difference in the catalytic activity between the two samples cannot be explained by a difference of surface area.


Psoriasis is one of the most prevalent chronic recurrent multifactorial diseases of the skin with a predominance of a genetic factor characterized by hyperproliferation of epidermal cells, the keratinisation impairment against the background of inflammatory reactions in the dermis, as well as lesions of the nails, joints and scalp, provoked by exogenous and endogenous factors. This disease can also be characterized by erythema, scaly elements, papules and plaques. According to the results of clinical and epidemiological research, about 3 – 4% of the population worldwide is diagnosed to have psoriasis, regardless of gender, age and ethnic group. The share of this pathology in the overall structure of skin diseases reaches from 1% - to 40%, according to various authors. They consider psoriasis as a systemic disease involving not only the skin, but also joints and viscera, and call it as a "psoriasis disease". The causes of psoriasis are immunological disorders and genetic defects. Recently inflammation in the skin of psoriasis patients is considered as an autoimmune process, in which a key role is played by T-cells sensitized to keratinocytes. One of the most probable self-antigens that trigger an immune inflammation in psoriasis may be cytosolic DNA. We describe the functions of the subpopulations of immune cells and the effects of secreted cytokines in the pathogenesis of psoriasis: the dendritic cells — Langerhans cells, plasmacytoid dendritic cells, CD11c+ dendritic cells; T-cells — T helper type 1 and 17, cytotoxic T lymphocytes, T-regulatory lymphocytes. The development of T-cell memory and intradermal proliferation of T-cells in the skin of patients plays an important role in the development of relapses of psoriasis. Therefore, the goal of further research is to carry out more in-depth study of the immunopathogenesis of psoriatic disease that will reveal new targets for the treatment of this dermatosis.


In this paper, a set of generalized strictly diagonally dominant matrix are discussed.

Finally, two numerical examples for the effectiveness of the proposed theorem are presented.


Because American outer space policy was ranked in relatively weak position among the national security strategy,the U.S. was not the first state to launch satellites. After the Soviet's emission of Sputnik 1,the U.S. administration established the objective of manned space program, emphasized the practical application and the value of scientific study. The outer space policy and activity in this period carved out the outline of the U.S. spaceflight thereafter.


Control of Fusarium vascular wilt on carnation using soil bio-disinfection in south west of Spain Non-chemical alternatives to 1,3 dicloropropene + chloropicrine (AGROC) used for the control of Fusarium wilt of carnation were evaluated in field experiments. This disease is a limiting factor for carnation cultivation for two consecutive years in all the Mediterranean regions. This period is needed for an acceptable yield. Soil disinfection is based on composted organic matter combined or not with solarization and grouped under the denomination of biodisinfection: Several organic materials were tested: compost of alperujo with and without solarization (31 days), post-harvest residues of compost of carnation and chrysanthemum post-harvest residues with and without solarization, compost of carnation and chrysanthemum post-harvest residues + hen manure with and without solarization. The severity of the disease and flower production was weekly evaluated during the two years that lasted the experiment. Experimental results showed that soil biodisinfection using compost of carnation and


This book provides a low-temperature deposition method of ceramic-based high-k functional thick/thin films employing room-temperature aerosol deposition (AD) process. It's possible to deposit high density and quality ceramic films from initial nano-particles without any high-temperature process on almost any kinds of substrate. The AD process takes an advantage of the room-temperature deposition phenomenon for the embedded capacitor technology that is based on three-dimensional integration of passive components with the low-melting point materials such as metals and plastics. Consequently, in order to realize the embedded capacitor technologies using the AD process, several investigations for high capacitance density, dielectric strength, and tolerance were introduced in this book.


. In response to recent biologists needs, we propose to lay the foun-dations of a stereo vision-based system for monitoring honeybees in 3D at the beehive entrance. In this context, this article highlights difficulties and introduces some solutions for problems related to the detection of the bees and tracking them in 3D under uncontrolled conditions. This study is a prerequisite for our next step that aims to detect and analyze behaviors of the bees based on their trajectories and additional external data such as the weather or health conditions.


A fastening device (4) for a cover (3) below a front hood (2) of a motor vehicle has an elastic fixing element (11) for holding a as radial expansion of a shaft (8) formed extension (9). Upon depression of the cover (3), the fixing element (11) disengages from the extension (9) and passes through the shaft (8). Thereby, the fastening means (4) is designed resilient and reduces the risk of injury in a head impact of a pedestrian.


A reasonable width of the coal pillar is very important to the surrounding rock control of the gob‐side roadway. An unreasonable width of the coal pillar will make the roadway to be located within the range of strong mining influence, leading to severe deformation of the roadway. Severe subsidence at the coal pillar side of the roof and serious coal pillar deformation are problems caused by strong dynamic pressure due to mining in the gob‐side coal roadway. This paper studies the surrounding rock instability mechanism and rational coal pillar width of the gob‐side coal roadway under the influence of intense dynamic pressure. The results show that: (1) Under the condition of large mining height, the roadway overburden is a hinged structure, and an unreasonable coal pillar width makes the gob‐side coal roadway to be located below the main roof fracture line. The rotary movement of the key block of the main roof is the main reason for the roadway deformation. (2) According to the evolution law of stress field, displacement field and plastic zone of surrounding rock of roadway under different coal pillar widths during roadway driving and mining were studied, and it is concluded that a 6‐m‐width coal pillar is the most reasonable. (3) Based on the stress distribution and plasticizing range of surrounding rock in a narrow pillar roadway, the combined support scheme of "anchor cable + grouting + single prop" is proposed and applied to engineering practice. The practice results show that the roadway deformation is well controlled, and the safe mining of the working face is realized.


Although it is normal to swallow air, excessive air swallowing is liable to produce discomfort in the stomach, stomachache, the post-prandial feeling of fullness and belching. This condition is called pneumophagia and is a form of functional dyspepsia. We report a case of functional dyspepsia due to malocclusion in a woman in her sixties who complained chiefly of malocclusion and breathing difficulty. The patient first sensed malocclusion after receiving a bridge in region (5)(6)(7) at dental clinic A in the autumn of year X-1. She asked the dentist of A dental clinic about this condition and he answered that there was no occlusion problem. She next visited dental clinic B, where she asked the dentist to remove the bridge. A temporary bridge was provided but her condition worsened with insomnia, breathing difficulty, flatulence of the stomach and decreased appetite. She visited doctors of internal medicine and the ear, nose and throat but even thorough examination by them revealed no cause. She then returned to dental clinic A to inquire about her condition. The dentist advised her to receive an examination at dental hospital C, which she visited in year X. A dentist of the department of dental prosthesis adjusted the occlusion but her condition still worsened, so the dentist referred her to the chief author of this paper. We provided combined treatment together with a psychiatrist from the first examination, providing both reasoning and medical treatment in the form of supportive psychotherapy and checking of occlusion at the department of dental prosthesis. Her sense of malocclusion gradually receded and her condition improved.


Abstract This article reviews literature in aphasia rehabilitation in the English-speaking world. Although attempts have been made to incorporate literature from other continents, the major bias is toward North America. Four themes are emphasised. They are (1) advances in neuroscience that have already realised influences in language rehabilitation and some that have potential influence for the near future; (2) effects on language rehabilitation that have resulted from the worldwide acknowledgment and acceptance of the International Classification of Functioning, Disability, and Health (ICF); (3) the growing emergence of psychosocial concerns in the management of aphasia; and (4) present and future applications of technology to aphasia rehabilitation. For the sake of manageability, the review is largely limited to the rehabilitation literature of the decade from 1998, and to published or in-press work that is programmatic in the sense that it represents more than a single publication.

ABSTRACT Part 2 of this study investigates the implications of random, small-scale contaminant concentration variability in soil for reliance on discrete soil sample data to guide environmental investigations. Random variability around an individual point limits direct comparison of discrete sample data to risk-based screening levels. "False negatives" can lead to premature termination of an investigation or remedial action. Small-scale distributional heterogeneity of contaminants in soil is expressed as artificial, seemingly isolated "hot spots" and "cold spots" in isoconcentration maps. Surgical removal of hot spots can lead to erroneous conclusions regarding the magnitude of remaining contamination. The field precision of an individual discrete sample data set for estimation of means for a contaminant in a risk assessment is not directly testable. Omission of "outlier" data in order to force data to fit a geostatistical model distorts estimates of mean concentrations and introduces error into a risk assessment. The potential for such errors was pointed out in early USEPA guidance but largely ignored or misunderstood. Decision Unit and Multi Increment sample investigation methods, long known to the agricultural and mining industries, were specifically developed to overcome these inherent shortcomings of discrete sampling methods and provide more reliable and defensible data for environmental investigations.

Introduction In 1917 Sir William Osler, in his Oration to the Medical Society of London, referred to the 20,000 syphilitic stillbirths which Sir Arthur Newsholme estimated then occurred annually in this country, and the numerous cases of eye, ear, bone, and joint, and-above all-nervous and mental disease which are due to congenital syphilis. In 1928 and again in 1930 Colonel Harrison referred to " the 16,000 and probably many more syphilitic expectant mothers who should be under treatment annually for their syphilis but are not." In 1930 Marjorie SmithWilson, using two different methods of computation,


We report on results from anisotropy of magnetic susceptibility (AMS) analyses carried out on weakly deformed fine‐grained sediments from the Northern Apennine orogenic system (Italy). We sampled 63 sites from preorogenic, synorogenic, and postorogenic sequences, which differ in age, composition, depositional environment, degrees of deformation, and tectonic regimes. The magnetic fabric is typical of weakly deformed sediments, with a magnetic foliation subparallel to the bedding plane and a magnetic lineation well defined in this plane. Northern Apennine chain deposits are characterized by strongly oblate magnetic susceptibility ellipsoids, indicating that the magnetic fabric is the result of both compaction process and tectonic load experienced by the sediments during diagenesis and orogenic events. The orientation of magnetic lineation is significantly different depending whether the studied sites underwent extensional or compressional tectonic regimes. In the Northern Apennine chain, the magnetic lineation is mostly oriented NNW‐SSE, parallel to the main compressional structures. It suggests a tectonic origin of the magnetic lineation with an acquisition related to the Apennines compressional phases. In the extensional Tuscan Tyrrhenian margin, magnetic lineation is oriented ENE‐WSW, almost perpendicular to the main extensional faults, which represent the main deformation elements of the area. Our results demonstrate a close relationship between the shape and orientation of magnetic fabric and the tectonic history of rocks, confirming that AMS represents a valuable tool to investigate the tectonic history of weakly deformed sedimentary rocks.


Here we report a fully non-inductive H-mode operation with a sporadic-small-edge-localized mode(ELM)-dominant pedestal realized in EAST with a tungsten divertor, where the normalized electron collisionality at the pedestal top is estimated below unity. This is regarded as the expansion and/or supplement of our previous research having been preliminarily reported (section 4.2 in (B N Wan et al 2017 Nucl. Fusion 57 102019)) in the EAST overview article contributed to the special issue on FEC 2016 summaries and overviews. In this operation, spontaneous avoidance of large ELMs is realized reproducibly, for the first time on EAST, at a lower collisionality (below unity) at the pedestal top, profiting from high heating power. Besides, this regime shows the well controlled bulk plasma density and light impurity concentration, good energy confinement with H98, (y2) ≃ 1, together with a loop voltage very close to zero. All of these features are considered critical to a steady-state operation with high performance, which EAST is on target to demonstrate in the near future in support to the International Thermonuclear Experimental Reactor (ITER). However, this operation regime suffers a continuous accumulation of medium-/high-Z impurities, which may seriously limit its sustainability. The resonant magnetic perturbation (RMP) with a dominant toroidal mode number n = 1 has been employed for assisting exhaust of heavy impurities, which is, unfortunately, not successful since the RMP with an effective poloidal spectrum always brings back large ELMs. This scenario transits to an ELM H-mode regime as plasma current is decreased, and elimination of large ELMs is well reproduced by ELITE simulation. Finally, we present a discussion on the potential mechanism eliminating large ELMs, which seems to highlight the LHW-induced profound change in edge magnetic topology.


Astrid Anderson, Landscapes of Relations and Belonging: Body, Place and Politics in Wogeo, Papua New Guinea, New York and Oxford: Berghahn Books, 2011, 262 pages.Wogeo is a smallish island off Papua New Guinea's north coast and is well known to Melanesianists through Ian Hogbin's publications from the 1930s to the 1970s. Hogbin is also a large presence in island memory, and Anderson is acutely conscious of working in his shadow: islanders understood her task to be filling in Hogbin's account in recording kastom - traditional culture as locally conceived. Much of Hogbin's record survives scrutiny, and where there are discrepancies, islanders are often tempted to defer to his version. In other cases, however, Anderson is in a position to offer important correctives, as in her discovery of (rarely acknowledged) matrilineages.The general picture of Wogeo kastom that emerges is both clarified and complicated by Anderson's treatment. Hogbin struggled for years with several different approaches to understanding Wogeo society. Many of his difficulties stemmed from an attempt to identify descent rules defining groupings and processes of succession. Anderson tackles these questions with the benefit of more recent approaches to Melanesian sociality, concluding that key processes are organized through diverse pathways of claims whose deployment is a matter of tactics and debate. Although she invokes Wagner and Strathern's ideas of composite persons with multiple identities ("dividuals"), it is not hard to see anthropology's more general shift to a focus on agency at work here.Hogbin was tempted to see Wogeo flexibility as tantamount to the absence of a system, whereas Anderson shows that, if anything, it is the system's elaboration that enables intricate political maneuvering. Claims to land or title, for example, can be argued on the basis of patrifiliation, residence, ritual participation, histories of use, matrilineal descent or affinity. The fact that genealogical ties are in play only multiplies the options: individuals bear the names of deceased villagers, and a combination of astute naming, strategic adoptions and advantageous marriages ensures that there is no shortage of genealogically plausible candidates for any particular claim.Anderson is at her best when describing the politics of rebuilding named houses, in which the full panoply of arguments is mobilized to lay claim to individually named roof rafters. Traditionally carved and painted, these rafters are the material register of rights to specific tracts of land, while the thatch contributed by supporters secures their subsidiary rights.

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy UNDERSTANDING AND REDUCING DISPERSED FIXED-DELAY INTERFEROMETRIC DATA FOR EXTRASOLAR PLANET SEARCHES By Julian Christopher van Eyken December 2007 Chair: Dr. Jian Ge Major: Astronomy The dispersed fixed-delay interferometer represents a new instrument concept for high-precision radial velocity surveys for extrasolar planets. A combination of an interferometer in series with a medium resolution spectrograph, it has the potential for performing multi-object surveying down to faint magnitude limits, where previous radial velocity techniques have been limited to observing only one target at at time. The sample of relatively bright stars that can quickly be surveyed using traditional radial velocity techniques with current technology is becoming exhausted, and the radial-velocity planet discovery rate is beginning to level out. Because of the large sample of extrasolar planets needed to perform statistical analyses to be able to understand aspects of planetary formation and evolution, such a multi-object instrument represents the next logical step in instrumentation for extrasolar planet research. As a useful by-product, the instrument has the potential to provide simple measurements of the projected rotational velocities of stars. The development of this instrument has necessitated the development of new data reduction procedures to efficiently and reliably turn the raw data into meaningful results, and a careful consideration of precision levels and sources of error. This in turn has required fleshing out a detailed understanding of the physical principles of the instrument. The single-object Exoplanet Tracker installed at Kitt Peak National Observatory and the multi-object W. M. Keck Exoplanet-Tracker at Apache Point Observatory are the first


Background: Although mixed venous oxygen saturation(SvO₂) has been established as a useful measure of whole body oxygenation, SvO₂ must be measured through a pulmonary artery(PA) catheter. We performed this study to evaluate whether central venous oxygen saturation(ScvO₂) could substitute for SvO₂, and whether SvO₂ reflects cardiac output. Methods: Twenty five patients were studied. Thirteen patients(GA Group) had PA catheters inserted during general anesthesia, and twelve(ICU Group) patients in the intensive care unit had PA catheters inserted for management of critical illnesses. In each patient, blood samples for SvO₂ and ScvO₂ were drawn separately from the PA and CVP ports of a PA catheter, and cadiac index(CI) was measured. Results: Mean ScvO₂ was significantly higher than SvO₂ in both group, but the differences of SvO₂ and ScvO₂ were only about 2.5%. Correlations of SvO₂ and ScvO₂ were very high in GA and ICU Groups(r=0.92, 0.95, respectively). SvO₂ was weakly related to CI in GA Group(r=0.64), and in ICU Group(r=0.50) Conclusions: We conclude that ScvO₂ can be a useful estimate of SvO₂, but SvO₂ does not reliably reflect cardiac index.

Purpose – The objective is to describe the "ethnocentricity" (i.e. geographical affiliation of editor(s), editorial board(s), editorial review board(s) and author(s)) of selected journals in services management.Design/methodology/approach – The sample is restricted to the examination and comparison of five top journals in services management during a six‐year period. In total, the content analysis consisted of 1,189 articles.Findings – The authors contend that there is in part a troublesome and challenging "ethnocentricity" in some of the examined journals.Research limitations/implications – The impact of "ethnocentricity" is underestimated in the examinations of academic journals in the field of services management. It is an important issue that needs to be raised and discussed in literature, due to the paradigmatic influences that it may have on the journal and its characteristics – in extension, the journal ranking and the journal quality.Practical implications – The authors provide some suggestions, a...


Abstract. Barone has described a method for generating independent realizations of a vector autoregressive moving‐average (ARMA) process which involves recasting the ARMA model in state space form. We discuss a direct method of computing the initial state covariance matrix T0 which, unless the number of time series is large, is usually faster than using the doubling algorithm of Anderson and Moore. Our numerical comparisons are particularly valuable because T0 must also be computed when calculating the likelihood function. A number of other computational refinements are described. In particular, we advocate the use of Choleski factorizations rather than spectral decompositions. For a pure moving‐average process computational savings can be achieved by working directly with the ARMA model rather than with its state space representation.


The article aims to apprehend, from a perspective close to a phenomenological criticism of the structure of the symbolic contents, those properties of emotion and thought which govern the imago poetica of Chilean Pablo de Rokha, and which serve as intermediaries between the poet's emotional sensibility and his relation with the world magically represented —in addition to stylistic characteristics and a relevant aesthetic referentiality in the context of the historical avant-garde, which benefit the critical reception of his poetry. Parting from one of the poems of Cosmogonia, an example of a fine exploitation of techniques assimilated from the different «isms»—, the article will offer a general view of De Rokha's poetics in his first period, examining its relation to the philosophy of Heidegger, Schopenhauer and Nietzsche..., through an odocriticism which separates into the active interpretation of imagery and ideology and into the dynamic apprehension of the intentional elements of poetic meaning.


Leukemia is a malignancy of the hematopoietic system, which consists of the infiltration of bone marrow from leukemic blasts, due to their continuous proliferation. The study of this disease is particularly important in children, as leukemia is the most common type of cancer observed during childhood, accounting for 29% of all childhood malignancies. Among leukemias, Acute Lymphoblastic leukemia (ALL) accounts for 76% of all childhood leukemic cases. During the last decades, there has been a tremendous progress concerning the diagnosis and therapy of ALL, as overall survival rates (OS) and disease-free survival rates (DFS) reach up to 90% and 80%, respectively, in developed countries. However, there are still challenges to overcome, as even with the establishment of modern therapeutic approaches, 20% of children experience relapse and poor prognosis with high mortality rates. Moreover, the therapeutic protocols of ALL stratify most patients in intermediate or high risk groups, leading often to patients' overtreatment, which is followed by acute or late side effects. Therefore, apart from the clinically established prognostic markers, it is essential to identify new molecular markers, capable of early disease detection and precise patients' prognosis, which will predict, as early as possible, the risk for relapse and patients' response to treatment. The ultimate task is the development and the establishment of individualized and targeted therapeutic schemes, which will be based on the cytogenetic abnormalities and gene expression profile of each patient and will eliminate the side effects of chemotherapy treatment.Apoptosis deregulation, including the abnormal expression of its master regulators, BCL2 family genes, has been reported in various studies focused on leukemogenesis and has been correlated to patients' outcome and resistance to chemotherapy. Thus, the discovery of the deregulated pathways and molecules involved in the upstream regulation of apoptosis and BCL2 family members, resulting in treatment failure and adverse prognosis, is of outmost importance. miRNAs represent an example of these molecules. They are a class of non-coding RNAs, 21-23bp, which regulate mainly post-transcriptionally other mRNAs. Researchers have revealed the implication of miRNAs in all aspects of the disease, from initiation and progression, to resistance to drugs and chemotherapy outcome in terms of relapse and death. Taking into account the potential of miRNAs as molecular markers of leukemia, the present Ph.D. Thesis performed, for the first time, the expression analysis and the evaluation of the clinical utility for childhood ALL of the miRNAs, miR-125b, miR-143, miR-182 and miR-195, which target BCL2 family genes, among others. The aim of the study was to reveal their potential as biomarkers in ALL differential diagnosis and in predicting patients' treatment response and survival. MiR-125b has been the research topic of numerous studies that have focused on cancer, attributing to it either an oncogenic, or a tumor-suppressive role. It targets anti-apoptotic genes, such as BCL2, BLCW and MCL1, as well as proapoptotic genes, such as BAK1, BMF and TP53. Apart from its role in apoptosis, miR-125b promotes carcinogenesis through the induction of cellular proliferation and the inhibition of cellular differentiation. In leukemia, miR-125b can be found up - or downregulated, depending on the type of malignancy, while its abnormal expression has been linked to chemotherapy resistance. MiR-125b expression levels have been associated with the presence of specific cytogenetic abnormalities, as well as with resistance to vincristine and daunorubicin. Nevertheless, its value in differential diagnosis and in predicting disease outcome has not been estimated yet. MiR-182 plays a significant role in cellular physiology, as it is involved in the regulation of different pathways, including AKT/FOXO3A, p53, apoptosis, WNT and DNA repair. Studies in cancer have reported the deregulation of miR-182 expression, but there is not a common expression profile between different types of neoplasms. As a result, miR-182 functions either as a tumor-suppressive gene, by targeting BCL2, BCL2L12, RGS17 and CREB1, or as an oncogene, by targeting FOXO1, FΟΧO3, BRCA1, RsECK and MIM. However, there are not many studies focusing on the expression motif of this miRNA in hematological malignancies and correlating it with patients' prognosis and outcome. MiR-143 has been reported to possess a tumor suppressive function, as it is often underexpressed in cancer, including leukemia, such as ALL, AML, CLL and Burkitt's lymphoma. Normally, it is involved in the PI3K/Akt/mTOR pathway, inhibiting cellular proliferation and invasion, while it promotes apoptosis, by targeting ERK5, AKT, KRAS and BCL2 among others. Moreover, it regulates the epigenetic modification of genes, through the downregulation of DNMT3A expression. Despite the studies performed in leukemic samples and leukemic cell lines, which have revealed miR-143 reduced expression, its role in childhood ALL progression and in patients' treatment response and survival, has not been reported yet. The last miRNA of this thesis was miR-195. In the majority of studies in cancer, miR-195 is downregulated and has been associated with poor prognosis. It is involved in cell cycle progression and apoptosis. Its gene targets, which support its tumor-suppressive role, include BCL2, BCLW, RAF1, CCND1, CCND3, CDK6 and E2F3, whose levels increase when miR-195 is underexpressed, inducing cell proliferation and impeding apoptosis. In leukemia, there are only a few studies which have presented roughly the expression pattern of miR-195, without however, attributing to it a specific role in disease formation and progression. To fulfill the aim of the study, a statistically significant number of bone marrow samples (272 in total) was collected and processed, from children with newly diagnosed ALL (N=125), from children of the same cohort at the end of the induction protocol (day 33) of treatment (N=83) and from children not suffering from any hematologic or other type of malignancy (N=64), which constituted the control group. The experimental procedures included the development and optimization of RNA extraction protocol from bone marrow samples, the spectrophotometric check of RNA quality and concentration, and the electrophoretic check for RNA degradation. Furthermore, polyadenylation and reverse transcription took place for the production of cDNA. To check the quality of all the aforementioned procedures, specific primers were designed and PCR reaction was optimized for the semi-quantitative evaluation of the reference gene SNOR48 and the studied miRNAs. Moreover, qReal-time PCR methodologies were developed for the quantification of the miRNAs of interest, using the fluorescent SYBR Green I assay. The expression analysis was carried out using the comparative CT, 2-ΔΔCT relative quantification method. The evaluation of the clinical significance of the studied miRNAs was performed by an extensive biostatistical analysis of the experiments' results, using a detailed database of patients' history, clinicopathological and follow-up data. The analysis of miR-125b revealed its significant downregulation in childhood ALL patients compared to the control group (p=0.004), and its ability to distinguish normal from leukemic BM samples (ROC curve AUC: 0.628; 95% CI 0.548–0.707; p=0.004 and univariate regression analysis OR: 0.477; 95% CI 0.288–0.790; p=0.004), independently of patients' age and gender (OR:0.507; 95% CI 0.305–0.842; p=0.009). In addition, reduced miR-125b expression on disease diagnosis was correlated with unfavourable prognostic features, such as T-ALL and (p=0.037) and initial WBC≥50,000/μl (p=0.004). Moreover, decreased miR-125b levels on childhood ALL diagnosis were associated with significantly stronger risk for short-term relapse and poor OS of the treated patients, using Kaplan-Meier survival curves (p=0,005 and p=0.013, respectively) and univariate Cox regression analysis (HR: 4.253; 95% CI1.411–12.82; p=0.010 and HR: 3.072; 95% CI 1.209–7.806; p=0.018, respectively), while multivariate models confirmed miR-125b independent prognostic value for patients' risk for relapse or death (HR: 3.891; 95% CI: 1.195–12.67; p=0.024 and HR: 2.963; 95% CI:1.079–8135; p=0.035, respectively). Interestingly, the downregulation of miR-125b on diagnosis was able to discriminate patients at higher risk for short-term relapse and worse survival outcome, despite the presence of favourable prognostic markers, such as B-cell immunophenotype (p=0.009 and p=0.003, respectively), initial WBC<50.000/μl (p=0.054 and p=0.047, respectively), good prednisone response on day 8 (p=0.003 and p=0.001, respectively) or M1 bone marrow response on day 15 of treatment (p<0.001 and p<0.001, respectively). Finally, patients with positive MRD on day 15 and low miR-125b levels on diagnosis presented a higher risk for relapse (p=0.010), while miR-125b downregulation on diagnosis identified a group of intermediate/high risk patients with also a higher risk for relapse or death (p=0.028 and p=0.010, respectively). At the end of the induction protocol (day 33), miR-125b was significantly upregulated compared to diagnosis in the majority (83%) of childhood ALL patients (p<0.001), while the higher values of day 33/diagnosis expression ratio were correlated with unfavourable prognostic markers, such as Τ-cell ALL (p=0.033), initial WBC≥50,000/μl (p=0.010), patients' age <1 or ≥10 years old (p=0.025) and intermediate/high risk stratification according to ALL-IC BFM (p=0.003). In addition, increased miR-125b levels on the 33rd day were associated with significantly stronger risk for short-term relapse (p=0.016) and poor OS of the treated patients, (p=0.016), which was confirmed by univariate Cox regression analysis (HR: 4.218; 95% CI 1.174–15.16; p=0.027 and HR: 4.21

. The dynamical evolution of the planetary rings is simulated by means of a numerical model in which particles interact through mutual attraction and inelastic collisions. We use a mixed simulation: a deterministic integration of the Ν - body problem for large distances ( "particle- mesh" method with an expansion of density and potential in spherical harmonics ) and a Monte Carlo treatment for the close encounters. The implementation is done in the Connection Machine in order to be able to make a detailed simulation using a greater number of particles ( of the order of 10 5 ). The deterministic calculation of the action of a shepherding satellite on the particles will allow us to study the effect of resonances on the formation and the evolution of the sharp edges of the rings.


We consider spatiotemporal systems and study their linfin and I2 robustness properties in the presence of spatiotemporal perturbations. In particular, we consider spatially invariant nominal models and provide necessary and sufficient conditions for system robustness when the underlying perturbations are linear time and spatially varying, unstructured and structured. It turns out that these conditions are analogous to the scaled small gain condition (which is equivalent to a spectral radius condition and an LMI for the linfin and I2 case respectively) derived for standard linear time invariant models subject to linear time varying perturbations.


A water conveyance tunnel is narrow and enclosed with a complex distribution of flow field. The performance of sensors such as Doppler log, magnetic compass, sonar, and depth gauge used by conventional underwater vehicles in the tunnel is greatly affected and can even fail. Aiming at the special operating environment and operational requirements of water conveyance tunnels, this paper designed an architecture suitable for pressurized water conveyance tunnel-detection autonomous underwater vehicles (AUVs). The tunnel-detection AUV (called AUV-T in this paper) with the architecture proposed in this paper could easily and smoothly complete inspection tasks in water conveyance tunnels, and field tests have verified the effectiveness of the architecture. Since an AUV in a water conveyance tunnel cannot go to the surface to rescue itself, in order to ensure its safety we designed the heterogeneous dual-CPU (Central Processing Unit) hot redundancy system based on dual communication lines. The reliability analysis showed that the system can significantly reduce the probability of AUV failure and ensure that the AUV can still be recovered even if it fails in the tunnel.

Factors that impact the development of neuroAIDS include monocyte expansion and activation, viral neuroinvasion and replication, and accumulation of activated and infected macrophages in the CNS. To better understand changes in monocyte/macrophage biology associated with the development of SIV encephalitis (SIVE) and neuroAIDS, we: 1) performed gene expression analyses using high density microarrays to characterize the response of monocyte subsets to SIV infection, 2) serially labeled CNS macrophages with fluorescent dextrans by intracranial injection and labeled myeloid progenitors in the bone marrow with BrdU to determine the timing of SIV neuroinvasion and macrophage recruitment/turnover in the CNS, and 3) performed in vitro studies to determine the role of PCNA expression in macrophages with SIV infection. We found the majority of macrophages in SIVE lesions were present in the CNS early in infection and productively infected macrophages were recruited to the CNS terminally with AIDS. We observed differences in the timing of recruitment, rate of turnover, PCNA expression, and productive infection between CD163+ and MAC387+ macrophages in the CNS. SIV infection was associated with induction of interferon stimulated genes in all monocytes, maturation of the intermediate monocyte subset, and increased rate of monocyte/macrophage recruitment to the CNS. Greater ratios of CD163+ to MAC387+ macrophages in the CNS were associated with SIVE. We also found that PCNA expression decreased macrophage apoptosis with SIV infection. Together, these studies suggest that the development of SIVE is a dynamic process and that continuous recruitment of activated monocyte/macrophage and reintroduction of virus from the periphery is required to drive CNS disease.
