Aim: The aim of this study was to evaluate the influence of implant metal artifacts on the detection of vertical root fracture of teeth adjacent to dental implants. Materials and Methods: Sixty extracted single-rooted teeth were randomly divided into vertical root fracture (VRF) and non-fractured groups (NVF) (n=30). Root fracture was induced in VFR, then teeth were positioned in the right and left posterior areas of epoxy-resin mandible model mesial and distal to two titanium implants. Three CBCT scan protocols were done: roots without implants, roots with implant without artifact reduction and roots with implant with artifact reduction. The images were evaluated by three observers. Area under the receiver-operating characteristic curve (ROC), diagnostic accuracy, sensitivity, and specificity were calculated. Results: Statistically significant difference was found in diagnostic accuracy of CBCT of vertical root fracture for all test groups with highest accuracy in group without implant (p =0.022). Post hoc pairwise comparisons showed statistically significant difference between accuracy of group without implants and group with implants and without algorithm (p=0.019). Sensitivity, specificity, positive and negative predictive values were higher in group without implant but there was no statistically significant difference between the three groups. Conclusions: Implant metal artifacts influenced the diagnostic accuracy, sensitivity and specificity for detection of vertical root fracture but still high levels were achieved and all image possessed high diagnostic quality. Artifact reduction tool improved the accuracy and specificity and can be recommended when the teeth involved are near dental implant.


Purpose

This research paper aims to explore the technological, individual and community factors influencing the use of popular Web 2.0 tools in library and information science (LIS) education to prepare LIS students for Library 2.0. The study was guided by the activity theory (AT) and technology acceptance model (TAM) of Davis as a lens. The study reveals a set of factors concerning the technical tools, subjective perceptions, goals of online discussion, social presence within a community, rules for participation and roles of the participants that affect their online engagement patterns.

Design/methodology/approach

This study was performed during the 2015 academic year; it used a descriptive analytical research approach for exploring and analysing technological, individual and community factors influencing the use of the popular Web 2.0 tools in LIS education.

Findings

The results show that at the technological level of the AT, educators in the sample found the WhatsApp instant messaging and Twitter to be the easiest tools to use, selecting those tools at, respectively, 73.2 per cent (standard deviation = 0.450) and 61.1 per cent (standard deviation = 0.490). WhatsApp and Twitter also lead at the individual level of the AT, as the most valuable platforms for sharing information and knowledge. Video, text and photo objects are the most commonly shared items, used by 90.7, 93.5 and 98.9 per cent, respectively.

Originality/value

This study may be useful to help information science educators to prepare graduates for the emerging Web 2.0 environments and to prepare students for Library 2.0.


In the present thesis, it will be presented a different method of pricing policies. This
method is based on the particular characteristics of the distribution function of the risk
we want to insure. Using this method, we no longer need to choose an utility function.
As a result, pricing does not depend on the actuary's subjectivity. In order to apply
this method, we only need to know the arithmetical values of statistical
measurements. Such measurements can be found using empirical data and therefore,
the distribution function is not needed. Since there are times in which is difficult to
find the distribution function of the risk, methods of approximation are suggested.
Using arithmetical examples, it has been proved, that these methods of approximation
are satisfactory. One of these approximations is the approximation of Normal Power
distribution.


Bile acids are central to enterohepatic signaling pathways activated through natural receptors, farnesoid X receptor [FXR mediates synthesis of fibroblast growth factor‐19 (FGF‐19)], and G protein‐coupled bile acid receptor 1 (GPBAR1, also known as TGR5). Although bile acid diarrhea (BAD) is more commonly encountered in ileal resection or disease, there is evidence documenting "idiopathic" BAD in about 20% of adolescents and 30% of adults presenting with chronic, non‐bloody diarrhea often attributed to irritable bowel syndrome. Mechanism(s) leading to increased hepatic synthesis and colonic bile acid levels in "idiopathic" BAD include reduced synthesis of FGF‐19 by the ileal mucosa, or genetic variation in hepatocyte proteins klotho β and FGF receptor 4 (FGFR4) that mediate negative feedback of bile acid synthesis. Purpose: The objective of this review is to summarize the diagnosis of BAD in adults and adolescents. In addition to 75SeHCAT retention for diagnosis of BAD, studies have validated fasting serum 7αC4 and FGF‐19, respectively, by‐product and inhibitor of hepatic bile acid synthesis, as well as fecal bile acid measurements. These assays are widely available through reference laboratories, and they are being simplified (eg, measurement of primary fecal bile acids in a random stool sample). BAD has also been identified as a co‐factor contributing to persistent diarrhea in other diseases in remission including inflammatory bowel disease, microscopic colitis, celiac disease, and neuroendocrine tumors. In summary, advances in diagnosis of BAD provide opportunities for generalists and pediatric and adult gastroenterologists to provide targeted treatment for BAD presenting as chronic non‐bloody diarrhea.


Background: Ankle sprain is an extremely common injury in soccer players. Despite extensive research, the intrinsic cause of this injury under noncontact conditions remains unclear. Purpose: To identify intrinsic risk factors for noncontact ankle sprains in professional soccer players. Study Design: Cohort study; Level of evidence, 2 Methods: One hundred professional soccer players were assessed in the preseason for potential risk factors of noncontact ankle sprains. The assessment included (A) ankle joint asymmetries (right-left) in isokinetic muscle strength, flexibility, proprioception, and stability; (B) somatometric asymmetries; (C) previous injuries; and (D) lateral dominance traits. Noncontact ankle sprains were prospectively recorded and diagnosed for a full competition period (10 months). Results: Seventeen of the players sustained at least 1 noncontact ankle sprain. Logistic regression revealed that players with (A) eccentric isokinetic ankle flexion strength asymmetries (odds ratio [OR] = 8.88; 95% confidence interval [CI], 1.95-40.36, P = .005), (B) increased body mass index (OR = 8.16; 95% CI, 1.42-46.63, P = .018), and (C) increased body weight (OR = 5.72; 95% CI, 1.37-23.95, P = .017 ) each had a significantly higher risk of a noncontact ankle sprain. A trend for younger players (OR = 0.28; 95% CI, 0.061-1.24, P = .092) and for players with ankle laxity asymmetries (OR = 3.38; 95% CI, 0.82-14.00, P = .093) to be at greater risk for ankle sprain was also apparent to the limit of statistical significance (.05 < P < .10). Conclusion: Functional strength asymmetries of the ankle flexors and increased body mass index and body weight raise the propensity for ankle sprains in professional soccer players. Age and asymmetries in ankle laxity are potential factors worth revisiting, as there was an indication for younger players and players with ankle instability to be at higher risk for ankle injury. Proper preseason evaluation may improve prevention strategies for this type of injury in soccer.


A variety of algorithms have been developed to compute an approximate polynomial matrix eigenvalue decomposition (PEVD). As an extension of the ordinary EVD to polynomial matrices, the PEVD will generate paraunitary matrices that diagonalise a parahermitian matrix. This paper compares the decomposition accuracies of two fundamentally different methods capable of computing an approximate PEVD. The first of these — sequential matrix diagonalisation (SMD) — iteratively decomposes a parahermitian matrix, while the second DFT-based algorithm computes a pointwise in frequency decomposition. We demonstrate through the use of examples that both algorithms can achieve varying levels of decomposition accuracy, and provide results that indicate the type of broadband multichannel problems that are better suited to each algorithm. It is shown that iterative methods, which generate paraunitary eigenvectors, are suited for general applications with a low number of sensors, while a DFT-based approach is useful for fixed, finite order decompositions with a small number of lags.


This study uses detrital zircon U-Pb geochronology from shallow-water carbonates of the Bighorn Dolomite in Wyoming, USA, to provide robust evidence for long-distance eolian sediment transport during the Ordovician. The Bighorn Dolomite was deposited in a shallow-water carbonate platform that developed approximately 10° south of the Ordovician paleoequator on the western edge of Laurentia. The ages and textures of detrital zircons from the Bighorn indicate that the grains were transported by winds through saltation and suspension from the paleo east where rocks of the Paleoproterozoic Trans-Hudson orogenic belt were exposed in present-day Manitoba and Saskatchewan. Our interpretation of long-distance eolian transport is consistent with the paleogeography of Laurentia and expected prevailing wind directions and draws on modern analogs where Saharan sediment is transported by trade winds for distances of more than 3000 km.


360- video is gaining a lot of interest because of the immersive feeling brought by such a technology. Several projection formats are used to represent this type of content. Equirectangular projection (ERP) is one of the most widely used projection scheme for 360 panoramic content. The main drawback of ERP is its latitude dependent sampling density unlike conventional 2D content. Consequently, conventional 2D codecs such as HEVC are not optimal for the coding of ERP projected 360 content. To cope with this dependency, this work proposes an adaptation of motion vector resolution and minimum width of the coding block depending on its latitude. Experimental results show up to 0.5% BD-rate savings for motion contained sequences with 15% encoding time reduction in random access configuration.

The long history of art and science that includes Egyptian, Asian, and Greek philosophers and innovators of the Renaissance, such as Leonardo Da Vinci, offers hypotheses about the neuro-anatomical substrates that serve our conscious responses to design. In the 1600s, René Descartes described a dualism between the brain and the mind and, to this day, many continue to believe that the mind cannot be studied or measured. However, over the millennia that followed Descartes ' writing, the development of electrophysiological and imaging techniques have revealed that the brain can be considered the organ that produces the mind. Wearable, wireless, and computational techniques have developed that allow us to study the brain ' s form (neuroanatomy) as well as its function (neurophysiology) in alert subjects, awake patients, and participants in real-world settings. With the bene fi t of such methods, long-held myths about the mind and brain can be explored using carefully controlled studies in laboratories and in real pro-jects. In studios, students and scholars of design now deploy multiple methods to track the brain ' s and body ' s responses as we conceive of, experience, and test design outcomes in pre-and post-occupancy studies. The brain, mind, and body may thus be considered together in a new framework that no longer compares the neurons of the brain to a hard-wired computer, but rather an integrated dynamic system that changes with the experience of design. Neuroscience offers new means to explore the in fl uence of design while planning, creating, and evaluating a space. The neuro-design process can begin with and iteratively include existing bio-medical fi ndings and use a great many neuroscienti fi c tools to measure the responses of the brain, mind, and body. Qualitative subjective, and quantitative objective, observational, inter-ventional, or biomedical metrics may explore conscious, subconscious, and unconscious reac-tions to speci fi c attributes of the physical world. Thus, we can now study many questions

The aim of this research is to present the surgical technique of vaginal hysterectomy (VH) and discuss its advantages over other techniques. The work method was an integrative literature review, associating "hysterectomy" and "vaginal route/way". There were included 7 original articles, available in full, in the Portuguese, English and Spanish languages, published between 2000 and 2018, in the PubMed, SciELO and Lilacs databases. The study showed the anatomical characteristics of the uterus and the most used surgical technique in HV. The advantages of vaginal route in relation to other techniques have been described, among which the following should be highlighted: minimal invasion, lower incidence of complications and absence of visible scars. In contrast, also were reported the disadvantages and limitations. In summary, HV is a great option for uterine removal, and should be part of the therapeutic arsenal of gynecological surgeons, since its advantages outweigh the disadvantages described in the literature.


Virtual healthcare information technologies (HIT) are being adopted during the Covid-19 pandemic. We propose that even after Covid-19, virtual HIT can still have great potentials to address the challenges brought by the aging population on healthcare systems. The key questions are (1) what kinds of virtual HIT will be useful for seniors and (2) how these HIT will affect senior citizens' health-related quality of life (HRQL)? Centered on the concept of HRQL and grounded on task-technology fit (TTF) theory, this paper builds a framework of useful virtual HIT in the context of long-term care for seniors. The framework proposes senior citizens' human characteristics (i.e. restricted mobility, deteriorated working memory and attention, and social isolation) will influence their health-related tasks (task adaptability, autonomy, and interdependence). A set of virtual healthcare systems can be designed to fit seniors' tasks. These HIT will increase seniors' HRQL through increased task-technology fit (i.e. quality of healthcare, timeliness of healthcare, and relationships with seniors). This framework can serve as a base for researchers and practitioners in their endeavor to design more suitable HIT for seniors.


The taking and handling of civilian detainees during contemporary military operations is increasingly subjected to political, media and judicial scrutiny. This article argues that the most effective and efficient means of ensuring greater certainty, consistency and clarity in the identification and application of appropriate and relevant norms for dealing with detainees is to formalise those norms in a 'special legal regime'. It is only through increased formalisation and systematisation of legal principles, rules and standards that the appropriate balance will be achieved in determining the rights and obligations of both the civilian population and military forces. The author concludes by suggesting a number of principles that should form the basis of some fundamental norms required for this 'special legal regime'.

The design of electrical power distribution system of Marinas requires a special architecture to supply the distributed loads constituted by pleasure crafts. It must also provide for solutions to possible stray currents circulating through the earth and the water that can cause electrical hazards and corrosions. The authors suggest the adoption of a distribution operated at 1 kV and the TN-island System to supply each pleasure craft. This distribution system is an effective way to protect persons from shock hazards in installations with contained demand load, and to greatly limit electrical interferences among systems.


Based on the nature of brand relationship, it's a new perspective on brand crisis management to explore what kind of impacts the interactive relationship between consumers and brands would have on brand crisis. From the perspective of brand relationship, this paper defines brand as a state of the severe distortion and even temporary or permanent dissolution of brand relationship caused by widely spread negative incidents and puts forward an idea that brand crisis is a dynamic and evolutionary process which may be divided into three circulating phases: latency, outbreak and recovery. Brand relationship quality (BRQ) may be evaluated to judge which phase brand crisis is in, thus helping corporations accurately identify brand crisis, scientifically prevent and cope with crisis, better learn about crisis, and reduce the losses to the lowest.


Explored in this work are three texts: Cormac McCarthy's novel, The Road; Douglas Coupland's novel, Girlfriend in a Coma; and Robert Kirkman's ongoing serialized comic book, The Walking Dead. After a discussion of apocalyptic and postapocalyptic fictions and their ubiquity and popularity in contemporary culture, each work will be analyzed individually to explore each author's message regarding postapocalyptic concerns. These three texts have been chosen as each represents a point along a loose continuum of high-to-low art. Primarily, this thesis will focus on how each author approaches systems of meaning-making and systems of understanding in postapocalyptic settings and texts. This analysis will examine how characters must reevaluate and find new ways of understanding in order to navigate their postapocalyptic landscapes and how authors defamiliarize contemporary culture and society with these postapocalytptic texts.


The purpose of this paper is to summarize the conventions presently used to tabulate thermodynamic properties of chemical species, to show the reaction types for which these tabulations are and are not applicable, and to suggest alternative conventions that could extend the applicability of the conventions.


Since loitering is a suspicious behavior that often leads to abnormal situations, such as pickpocketing and terrorist attacks, its analysis attracts increasing research attention. In this paper, we present AntiLoiter, a practical loitering discovery system for surveillance. AntiLoiter can efficiently discover loitering candidates from longtime videos across multiple cameras. Most of existing systems mainly focus on how to detect or identify loiterers by behavior tracking techniques. However, the difficulties of tracking-based methods are known as that their analysis results are heavily influenced by occlusions, overlaps, and shadows. Moreover, tracking-based methods need to track the human appearance continuously. Therefore, they are not readily applied to longtime videos across multiple cameras due to the appearance discontinuity of criminal loitering. For instance, a suspect would probably come to the same place several times on different dates for preliminary inspections before a terrorist attack happens, where the loitering behavior is discontinuous. To solve this problem, we abandon the tracking method, instead, design a novel approach to efficiently discover loiterers based on their frequent appearance patterns for longtime videos across multiple cameras. Our approach simply yet effectively adopts existing face recognition techniques for loitering discovery. We conducted extensive experiments on both synthetic and real surveillance videos to evaluate the efficiency and efficacy of our approach. The experimental results show that our system can find out loitering candidates correctly and outperforms existing method by 100 times in terms of runtime.

Spatio and temporal variation in benthic macroinfaunal structure in saltmarshes from the Pará coast was described at four sites, sampled in April and November of 2008, representing peak conditions in the wet and dry periods, respectively. Differences in abundance and taxa were found among sites and between dates. High macroinfaunal abundance and number of taxa were associated with tall, dense vegetation and sand, and with high salinity, higher temperatures and low sediment organic matter content in November. Typically marine organisms, such as Halmyrapseudes spaansi, Capitella cf. capitata and ostracods of the Family Cypridae were identified as dominant taxa at this time and associated with relatively lower organic matter content in the sediment.


The nonrelativistic quark model with hyperfine color magnetic interquark forces is used to show that, when the relativistic nature of the photon--quark interaction is taken into account together with the proper treatment of the nucleon motion in the ..delta..--N transition, it is possible to obtain satisfactory agreement between the calculation and the experimental data on photo- and electroexcitation of the ..delta..(1230) isobar and on the proton elastic form factors up to momentum transfers k/sup 2/ = -2 GeV/sup 2/.


To reduce inconsistencies in citation instruction across the curriculum, the Gregg-Graniteville Library at the University of South Carolina Aiken developed a model of citation support that involved creating instructional materials, providing citation support at the reference desk and via appointment, and creating and delivering citation style workshops and instruction sessions. These efforts evolved into a multipronged model of collaboration that involved coordination within the library, with the campus writing room, and with the teaching faculty. The purpose of this paper is to provide an overview of this model, which is both collaborative and holistic in its approach, and to discuss the process of trial and error that has contributed to its growth and evolution.


Purpose: The purpose is to study the association of stone, ureteral, and renal morphometric parameters with the relevant outcome variables, i.e., complication rate, stone-free rate (SFR), and operating time of ureterorenoscopic lithotripsy. Although a safe procedure, it still occasionally has major complications. Computed tomography (CT) scan is often performed to diagnose ureteral calculi, providing opportunities for ureteral morphometry that may have a bearing on the outcome of the procedure. Materials and Methods: Ureteric, renal, and stone morphometric parameters were measured from CT of the abdomen and pelvis of the 110 patients with ureteral calculi who underwent ureteroscopic lithotripsy (URSL). Data were collected retrospectively in 25 patients and prospectively in 85 patients. Association of these parameters with the outcome variables of the procedure mentioned above was studied. Results: On univariate analysis, body mass index, stone size, and maximum ureteral wall thickness (MUWT) were found to have a significant association with URSL complications, SFR, and duration of surgery. On multivariable analysis, only MUWT was found to be an independent risk factor for URSL complications. In 90% of total patients with residual stones, MUWT was found to be >4.8 mm. Conclusion: Ureteral wall thickness of >4.8 mm is associated with prolonged duration of surgery and lower SFR. Patients with ureteral wall thickness of >4.8 mm at the site of ureteral stone who are planned for URSL must be counseled about the higher chances of residual stones and the need for additional procedure.


Using Grama's theory of hegemony to examine a growing crisis of authority erupting within American culture, this paper focuses on three popular, youth‐based television programs of the 1960s—The Monkees, The Smothers Brothers Comedy Hour, and The Mod Squad—and on how their themes of youthful disaffection, countercultural values, and political rebellion circulated and were made meaningful in the popular press. Although conflicts and struggles manifest themselves within other sectors of the social order, the field of popular culture is particularly valuable in showcasing breakdowns in consensus, the unmasking of coercive power, and the process of incorporating rebellious social formations back into a reconfigured hegemonic structure.


The article considers the history of relations between Russia and Belarus in the framework of the Union State in the light of the information counteraction, reflecting the difficult political and economic relations between the parties. Particular attention is paid to the search of a communicative compromise as a method of neutralization of informational confrontation between Russia and Belarus.


Shrimp farming has emerged as sunrise sector in the aquaculture scenario of India. The
present study revealed that personality characreristics such as social participation, information
seeking behaviour; marketing behaviour, annual income, economic motivation and farm size
together explained the largest per cent of the total variance on the overall extent of adoption
of technologies by Shrimp farmers. The second level of influential variables on the extent of
adoption were type of ownership and family size. The other factors on order of level of influence
were socio-psychological, material and socio-personal factors.


My first placement as a nursing student was on a ward with a heavy workload. I found the work rewarding and the patients a pleasure to nurse. The staff, however, were a different matter.


The decrease in oxygen content (deoxygenation) of coastal and oceanic waters worldwide has found to be worsened in recent decades. Recent findings indicate that the Peru-Chile margins, West African coast, the northern Indian Ocean and Bay of Bengal are increasingly vulnerable to deoxygenation events. This study observed the distribution of dissolved oxygen (DO) and found the Oxygen Minimum Zones (OMZ) in the Bay of Bengal spatially and temporally. DO data was collected from the World Ocean Database for all the years the inventory has available. A permanent hypoxic condition at the mid-layer depths (200m -900m) was observed in the shallower area. During monsoon season, due to meteorological turmoil of cyclone genesis and heavy rainfall, the area get enough oxygen. The vertical distribution is found to be as decreasing at first few hundred depths and then increasing from 1,000m to the bed. The sections show OMZs more in summer and winter; less in monsoon. The OMZs lie mostly at 200-500m depth along the continental slope or at mid-regions of the basin.


This paper briefly describes a portion of a joint multi-year research and development program between McDonnell Douglas Technologies Incorporated (MDTI) and New Aircraft and Missile Products (NAMP), both members of the McDonnell Douglas Aerospace-East (MDA-E) team. This ongoing program evolved from advanced radorne development to flight validation of full-scale hardware, including electrical and structural proof test verification, in just two and a half years. This paper focuses on the structural analysis and test effort leading to flight demonstration of an advanced F15 broadband nose radome. The broadband nose radome is a sandwich structure composed of cyanate ester syntactic cores with quartzlcyanate ester skins transitioning to a solid graphitelcyanate ester attachment region. This configuration represents a significant material, design and manufacturing advancement o\ler the F15 production filament wound, solid laminate glasslepoxy radome. The F-15 broadband nose radome successfully passed the structural proof test, passed preand postproof test inspection, and exhibited no permanent deformation due to the proof test. MDA-E presented the broadband radome for certification by the Air Force F15 Program Office and was granted permission for flight test on F15A aircraft No. 161, an uninstrumented production I;15 used for chase and target missions. MDA-E successfully completed nine flights, for a total tlight time of 13 hours. between 25 August 1993 and I I March 1994. Radome Technical Description The combined electrical and structural design goal of the broadband nose radome is to maintain F15 radome tit and function while improving electrical performance. The overall approach to reaching this goal is described herein in terms of genenrtiorzs. The first generation radome (Figure I ) is a sandwich structure fabricated with quartzlepoxy skins in a multi-stage cure cycle to validate the electrical design concept only. The broadband electrical performance is achieved by a basic radome wall design of five layers, better known as a Csandwich, in the radar window region. The second generation radome (Figure 2) is also a C-sandwich structure with three skin layers sandwiching two F-15 GEN I Epoxy Skins Multiple Cures and Foam Electrical Model


Utrophin (Utrn) is the autosomal homolog of dystrophin, the Duchene Muscular Dystrophy (DMD) locus product and of therapeutic interest, as its overexpression can compensate dystrophin's absence. Utrn is transcribed by Utrn‐A and ‐B promoters with mRNAs differing at their 5′ ends. However, previous central nervous system (CNS) studies used C‐terminal antibodies recognizing both isoforms. As this distinction may impact upregulation strategies, we generated Utrn‐A and ‐B promoter‐specific antibodies, Taqman Polymerase chain reaction (PCR)‐based absolute copy number assays, and luciferase‐reporter constructs to study CNS of normal and dystrophic mdx mice. Differential expression of Utrn‐A and ‐B was noted in microdissected and capillary‐enriched fractions. At the protein level, Utrn‐B was predominantly expressed in vasculature and ependymal lining, whereas Utrn‐A was expressed in neurons, astrocytes, choroid plexus and pia mater. mRNA quantification demonstrated matching patterns of differential expression; however, transcription–translation mismatch was noted for Utrn‐B in caudal brain regions. Utrn‐A and Utrn‐B proteins were significantly upregulated in olfactory bulb and cerebellum of mdx brain. Differential promoter activity, mRNA and protein expressions were studied in cultured C2C12, bEnd3, neurons and astrocytes. Promoter activity ranking for Utrn‐A and ‐B was neurons > astrocytes >  C2C12 > bEnd3 and bEnd3 > astrocytes >  neurons > C2C12, respectively. Our results identify promoter usage patterns for therapeutic targeting and define promoter‐specific differential distribution of Utrn isoforms in normal and dystrophic CNS.


Objective
To explore the role of beta-2 adrenergic receptor in the pathogenesis of infantile hemangioma.

Methods
In vitro cultured infantile hemangioma endothelial cells were divided into propranolol and isoproterenol groups. The propranolol groups were further classified into 5 groups to be treated with propranolol solutions at concentrations of 10, 15, 20 μg/ml, EGM-2 medium (blank control group 1) , and EGM-2 medium containing 0.16% DMSO (DMSO group) respectively, while the isoproterenol groups were classified into 4 groups to be treated with isoproterenol solutions at concentrations of 5, 10, 20 μg/ml and EGM-2 medium (blank control group 2) respectively. After 24-and 48-hour treatment, enzyme-linked immunosorbent assay (ELISA) was performed to measure the expression of beta-2 adrenergic receptor in cell culture supernatants in the above groups.

Results
After 24-hour treatment, 15-μg/ml and 20-μg/ml propranolol groups showed significantly decreased expression of beta-2 adrenergic receptor compared with blank control group 1 and DMSO group (all P < 0.05) . After 48-hour treatment, all the propranolol groups showed significantly decreased expression of beta-2 adrenergic receptor compared with the blank control group 1 (all P < 0.05) . However, the expression of beta-2 adrenergic receptor was significantly higher in the 10-and 20-μg/ml isoproterenol groups than in the blank control group 2 after 24-hour treatment (all P < 0.05) , and higher in the 20-μg/ml isoproterenol group than in the blank control group 2 after 48-hour treatment (P < 0.05) .

Conclusion
Propranolol can down-regulate the expression of beta-2 adrenergic receptor on the surface of vascular endothelial cells, while isoproterenol can up-regulate its expression.

respectively) were struck at Pergamon. If K. is right in arguing, on grounds of style and format, that the coins with the legend AAOA were struck at Tralles, there were only two mints altogether (apart from Aristonicus' short-lived travelling mint). Probably the timing and size of what appeared to be an individual city's issues depended on royal bounty and reflected royal needs. The evidence suggests that volume of production was very irregular, as one would expect, perhaps even more so than K.'s proposed absolute dates allow. It remains for others to discuss why the cistophoric standard was adopted, why, to judge from finds, Attalid cistophori circulated hardly at all outside the kingdom, and why 'foreign coins are almost unknown in cistophoric hoards' (p. 18). K. sees that 'the connection with the Roman denarius is unlikely' (p. 18 n..56), but does not refer to Will's suggestions (Histoire politique du monde hellenistique I. 155 ff.),.probably the most fruitful. The plates, illustrating 465 of the coins, are excellent. K.'s presentation of the later cistophori will be eagerly awaited.


I N the late eighteenth century, public health formed an integral part of the Bourbon campaign to revitalize the Spanish colonial enterprise and reinstate Spain as one of Europe's premier imperial powers. As frequent outbreaks of epidemic disease threatened the social, economic, and military well-being of the realm, colonial officials, medical experts, and members of the commercial elite struggled to find ways to counter and, ideally, to prevent the devastating effects of widespread illness. In doing so, they looked to the public health innovations gathering momentum throughout Europe. Throughout the eighteenth century, intellectuals and policymakers across Europe paid increasing attention to the cameralist notion that a state's wealth stemmed ultimately from its ability to ensure the health and continued growth of its population. Over time, this concept meshed with Enlightenment beliefs that nature exhibited an order capable of being understood and, eventually, manipulated by humanity. Because epidemics and other widespread disease outbreaks formed a part of this order, scientific inquiry promised to reveal the underlying causes of illnesses that threatened the welfare of the state and point the way to preventing their occurrence.1 These trends sparked initiatives to improve public health in capitals and major cities throughout Europe. Attention focused on controlling the spread of epidemics by restricting the movement of people and goods suspected


It should be noted that the book is not presented in a particularly 'reader friendly' style. It is largely a research report and reads as such, presenting a detailed analysis of data and discussion of research design and methodology. It would be unfortunate if the presentation deterred practitioners and others from the book as it contains useful material for those working in this area at all levels. The author provides a useful discussion in relation to the difficulties of research design and methodology in the child and family welfare program area and the publication is thus useful to read for those interested in researching child and family welfare programs. A particular asset of the publication is the bibliography which provides an excellent reference of research and literature in this area, and draws on literature from Australia in addition to the United Kingdom and United States of America.

Nowadays, there are many teachers that keep using the traditional teaching model in the educational processes, because their knowledge is transmitted in the same way that they were taught, this is a reality to which most of the primary and secondary students are exposed in the Institutions of the State.
For that reason, this essay has as objective to identify and to meet some of the causes that influence over the Physical Education Teacher at the moment to perform his Teaching Practice using a traditional model in the present.
Moreover, it is proposing some alternatives that lead to a change from a pedagogical view point from the investigation and the gathering information done to give support to this document.


Studies suggest that male sex, a diagnosis of bipolar disorder and a history of suicide attempt are risk factors for suicidal behavior.1,2 Psychosocial impairment is also associated with suicidality. Several lines of evidence indicate that testosterone may be involved in the pathophysiology of aggressive and suicidal behavior in males.1 In this study, we examined whether higher testosterone levels predict future suicide attempts in males with bipolar disorder and a history of suicide attempt. Sixteen male suicide attempters with bipolar disorder were included in the study. Four of them made suicide attempts during the followup period. We limited this study to previous suicide attempters in order to have a highrisk group for suicide attempt on followup and thereby enhancing statistical power. Recruitment and clinical evaluation of study participants were described previously.3 Briefly, to be included, patients had to have a diagnosis of a bipolar disorder based on the Structured Clinical Interview: be in a depressive or mixed episode, have at least one past suicide attempt, and be 18 to 75 years of age. All participants provided written informed consent as approved by the New York State Psychiatric Institute Institutional Review Board. We used the male subsample of subjects included in our previous research report4 and included prospective observational data. Current severity of depression and lifetime aggression, impulsivity, and hostility were assessed by the Hamilton Depression Rating Scale (HDRS), Aggression History Scale (BrownGoodwin, revised), Barratt Impulsivity Scale, and BussDurkee Hostility Inventory, respectively. The severity of suicidal ideation, hopelessness during the previous week, the degree of medical damage caused by the most lethal suicide attempt, and reasons for living were measured with the Scale for Suicide Ideation, the Beck Hopelessness Scale, Medical Lethality Rating Scale, and Reasons for Living Inventory, respectively. Baseline plasma testosterone was assayed using a doubleantibody 125I radioimmunoassay procedure. Patients were followed up prospectively for up to 2.5 years. t Test was used to compare baseline testosterone levels in study participants who did or did not make a suicide attempt during the followup period. Taking into account multiple reports indicating that aggressive behavior in males is linked to testosterone levels,1 we used Pearson's correlations to test the relation between testosterone levels and Aggression History Scale items. Cox proportional hazards regression was used to analyze the time to the first suicide attempt. Demographic and clinical characteristics of study participants are presented in Table 1. At baseline, males with bipolar disorder who made suicide attempts during the followup period had significantly higher testosterone levels in comparison with those who did not attempt


Silicon nanostructure surface fabricated from metal-assisted etching have been demonstrated as high sensitivity matrix-free laser desorption/ionization mass spectrometry chip. The silicon nanostructure morphology was found to have direct effect to the mass spectrometry ionization efficiency. Creation of different silicon nanostructure morphologies by changing the metal thickness, etching time and etchant composition in metal-assisted process was explored and its effects to mass spectrometry ionization efficiency was investigated in this paper.


This study were prepared the direct methanol fuel cell (Direct Methanol Fuel Cell, referred DMFC) anode catalysts Pt-ZrO2/C. Preparation and characterization of Pt-ZrO2/C eletrocatalysts for the purpose of improving DMFC performance. Here two-step process to prepare Pt-ZrO2/C electrocatalyst. The first step to synthesized ZrO2/C nanocomposite by co-precipitation method use ZrO(NO3)2.2H2O as precursor, Vulcan XC-72 as carbon support. Second, use the polyol reduction method with ethylene glycol as a reducing agent to reduce the Pt nanoparticles dispersed on ZrO2/C nanocomposite. And try to change different weight ratio of Zr and C, different heat treatment temperatures and carbon support modified by acid or base. In this study, using a scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction analyzer (XRD) to analyze the electrical properties on the surface of the electrocatalyst. The electrochemical characterization was examined by cyclic voltammetry (CV) and chronoamperometry (CA) in acidic solutions. The Pt-ZrO2/C electrocatalyst has the best MOR performance at 300 ° C. When the PZxCy-300 series of electrocatalyst weight ratio of Zr and C was 2 to 78, it was have the smallest Pt nanoparticles Pt (2.65 ± 1 nm). Meanwhile, both the ECSA (76 ± 6 m2/g Pt) and MOR efficacy (648 ± 35 A / g Pt) were high than commercial electrocatalyst E-TEK Pt(20 wt%)/C. Although the PZxCay-300 and the PZxCby-300 series electrocatalyst used carbon support modified by acid or base didn't have much more improvements MOR efficacy. But for CO tolerance ability and stability, it were significantly enhance.


In a lamellar structure with a density-difference between crystalline and non-crystalline layers, a new method for simultaneous determinations of the degree of crystallinity and the density-difference is proposed. This method utilizes the temperature dependent intensities of X-rays scattered through small angles on the basis of the idea that the temperature dependent parameters of the structure are both the density-difference and the non-crystalline layer-thickness. As an application of the method, drawn and well-annealed polyethylene is examined between -190 and 125°C. The volume-fraction crystallinity or the non-crystalline specific volume is determined as a function of temperature. The glass-like transitions are found at -123, -35 and 28°C. Above 55°C, the partial melting occurs and it is thermally reversible. During premelting, the thermally reversible tilting of the crystalline axis is found.


Three encouraging trends in special education are greater focus on instruction, emphasis on positive approaches to problem behavior, and greater reliance on scientific evidence. Next steps involving instruction should include research on modifications of instruction needed to accommodate learners with disabilities and on the place in which these modifications can best be made. In using positive approaches to teaching and behavior management, next steps should focus on making them typical in special education first, then on encouraging their use in general education. Regarding scientific evidence, next steps should be unambiguous preference for science and training special education teachers to rely only on scientific evidence.


In the major Dutch cities, social rented housing in post-war neighbourhoods has been demolished and largely replaced by more expensive owner-occupied and rental housing. Through residential mobility, these measures can trigger substantial population changes. This paper studies residents' social capital in two recently restructured neighbourhoods in the city of Rotterdam. It distinguishes between the stayers, movers and newcomers. In a neighbourhood context, social capital refers to the benefit of cursory interactions, shared norms, trust and collective action of residents. Survey data show that social capital is not only an asset of long-term stayers, but that in particular newcomers are relatively rich in social capital. Factors associated with higher levels of social capital are a higher net income, presence of households with children, stronger place attachment, higher perceived neighbourhood quality, homeownership and single-family dwellings. The expected future length of residence in the area appears of little importance for social capital.


When reading and writing about place and older women, questions often come to mind, among them: how do we capture the layered experiences of older women's lives? What are the characteristics that intersect or work together to impact women's overall health and other outcome measures? And what is the role of social structure or structural societal and historical elements contributing to women's varied experiences of aging? The articles compiled in this issue were selected because they each address these particular themes in the research about older women. Many of the articles build on Kimberl e Crenshaw's and Patricia Hill Collins' concept of intersectionality for older women. As Crenshaw (2017) explains, "intersectionality is the lens through which you can see where power comes and collides, where it interlocks and intersects. It's not simply that there's a race problem here, a gender problem here, and a class or LBGTQ problem there. Many times, that framework erases what happens to people who are subject to all of these things" (p. 1). I argue that these intersecting structures and identities must also incorporate age as a category (Mitra and Weil, 2016; Weil, forthcoming). As author Natalie Byfield suggests, intersectionality "allows researchers to reveal the underlying categorical boundaries such as race, class, gender, and age that are constructed as interlocking systems of oppression and must be negotiated as people (who are raced, classed, and gendered) navigate those boundaries as they move through the lifecourse" (in Mitra & Weil, 2016, pp. 48–49). The articles curated in this issue also add in another vital lens for research about and with older women, namely adapting Glen Elder's (1998) lifecourse perspective that looks at linked lives and the way that individual lives are bound within historical, temporal, societal, and cultural contexts. The approach suggests that we examine multiple identities, roles, and statuses of older women simultaneously. A lifecourse perspective integrates both a micro or individual level of analysis with macro or societal and structural-level components. The lifecourse perspective reminds us that we need to look at older women's lives in both an individual sense and also within the advantages and disadvantages of the time and place in which one lives and their intersectional characteristics. Combining an intersectional and lifecourse approach requires that we use various research designs and theoretical underpinnings as tools in unison as well as placing research in the context of societal structure. Older women's lives are layered and multi-leveled, and the goal of this issue is to capture and reflect this experience through the articles highlighted within it. Hamiduzzaman et al.'s (2021) article, "When I suffer from fever, I eat mangos": Determinants of health seeking beliefs and behaviors of rural older women in Sylhet, Bangladesh," applies socioecological theory to address how power relationships impact health-seeking behaviors for older women in rural Bangladesh which they define as a lower middle-income country (LMIC). They bring to light that these health-seeking behaviors result from both structural forces (such as poverty, lack of access to education, gender discrimination, and cultural and societal norms, etc.) and personal ones (such as mistrust of the medical community or preferred self-care practices) while being embedded in community and even social-justice norms. Interviews with rural older women and health professionals make evident the levels of intersection in the women's lives. As these researchers suggest, without such acknowledgements the wide range of health determinants and behaviors can mistakenly be reduced to the level of the individual woman. Three articles offer examples of how an intersectional lens can improve the way we conduct research about, and with, older women. The first, by Foster et al. (2022), "But... I survived": A


The Qushui collisional granitoids in Tibet is located in the middle part of the southern Gangdis Mts.,extending west to east parallel to the Yarlung Zangbo Suture.The granitoids mainly consist of mid-coarse-grained granodiorite and quartz diorite with abundant mafic microgranular enclaves(MMEs).Genetic mineralogical and petrographical studies suggest that the Qushui granodiorite and MMEs were generated by magma mixing and could not be evolved magma by FC(AFC)which is excluded by evidences as follows:(1)Oscillatory zoning of plagioclase with basic core and rim,but felsic mantle;(2)Amphiboles and biotites as inclusions in the rim of the feldspars,but seldom in the core;(3)Temperature increased from the core to rim of K-feldspar phenocryst;(4)Relatively high content of the Cr,Ni, Co elements in feldspars than those of the crust granitoids;(5)Contents of MgO in both amphiboles and biotites indicating their crust- mantle sources;(6)Needle shape of the apatites and amphiboles in MMEs implying the process of fast cooling.Pressure and temperature estimated with mineral Geothermo-barometers further support magma mixing is the main process of the Qushui granitoids and enclaves due to different emplacement depth between the host rocks and their enclaves,but approximately the same forming temperature.

We report a case of a 92-year-old man complaining of epigastric pain, which an US first and a CT scan later revealed to be related to a large gallstone causing cholecystitis. After the patient had refused surgical treatment for this condition, he was again referred to our Emergency Department presenting with a clinical picture of gastric obstruction. A new CT scan showed the classic Rigler's triad, characterized by pneumobilia, gastric distension and gallstone in the duodenal lumen, which was pathognomonic for a rare form of gallstone ileus named Bouveret's syndrome. The cause of this event was found out to be the chronic inflammation of gallbladder wall and its consequent erosion, which led to formation of gallbladder-duodenum fistula and the movement of the gallstone from the gallbladder to the duodenum where it impacted. This is a high morbidity and mortality condition, which affects mostly elderly people and needs early diagnosis and surgical treatment.


Low-frequency electromagnetic fluctuations dominate the wave spectrum observed during strong plasma flows in the region upstream of a cometary nucleus and in the plasma sheet boundary layer of the Earth's magnetotail. A theoretical framework is established in the long-wavelength limit for nonresonant instabilities in a multibeam plasma, for any number of beams. Both the growth rates of the instabilities and the ultimate levels of magnetic field turbulence are given. A two-beam plasma models the contamination of the upstream solar wind by cometary material, whereas a three-beam model is invoked for the plasma sheet boundary layer, with two counterstreaming proton beams in the presence of an oxygen beam. If the two proton beams by themselves already excite a low-frequency instability, the injection of oxygen at rest in the center-of-mass frame does not chaneg the instability characteristics. Where the two proton beams alone are stable, a sufficient amount of oxygen with a sufficient velocity offset in the center-of-mass frame can render the plasma sheet boundary layer unstable. In both cases, the theoretical levels of low-frequency turbulence are in good agreement with observations and/or numerical simulations.


Many recent ASICs include both analog and digital circuits, called mixed-signal integral circuits, to realize required functions on one chip. The comparator circuit is a principal element in the mixed-signal integrated circuit. In this paper we discuss a method for testing CMOS comparators. The method is current testing using both the upper limit and the lower limit. Bridging faults and break faults are assumed on the circuit layout and are analyzed by a circuit simulator. We examine the efficiency of fault detection by current testing. The result of the test shows that the proposed testing method has the highly fault coverage more than 94 percent.<<ETX>>


Aquatic bryophytes are frequently used as biomonitors for trace metals in aquatic ecosystems. Nevertheless, their special characteristics also allow using them as biosorbents to clean industrial wastewaters. As biosorption is a low-cost and effective method for treating metal-bearing wastewaters, understanding the process kinetics is relevant for design purposes. In this study, the ability of the aquatic bryophyte Fontinalis antipyretica to remove lead from simulated wastewaters was evaluated. Previously, the effect on biosorption of parameters such as the initial solution pH, contact time and initial metal ion concentration was investigated. The biosorption process is highly pH-dependent, and the favorable pH for maximum Pb2+ adsorption on the aquatic moss was found to have an optimum value in the range 4.0–6.0. The equilibrium sorption capacity of lead by Fontinalis antipyretica increased with the initial metal concentration. For an initial metal concentration of 10 mg L−1, the uptake capacity at equili...


This paper proposes a modular isolated dc-dc converter, based on the input-series and output-series (ISOS) association of the full-bridge PWM (FB-PWM) dc-dc converter with capacitive filter. The main attribute of the proposed architecture is its ability to provide self-balance of the input and output voltage across the individual converters, without voltage loop control scheme, both in the steady state and transient operations. Circuit operation, theoretical analysis and modeling are included in the paper, along with experimental results taken from a laboratory prototype with four modules, 1600 Vdc total input voltage, 1600 Vdc total output voltage, 4 kW output power, and 40 kHz switching frequency. Possible applications include high voltage power supplies, solid state transformers, dc current distribution systems, and renewable electric energy systems.


Objective To developa 3-D finiteelement (FE) model of anterior screw fixationon lower thoracic vertebra,evaluate and modify the stress of screw and the stick. Methods The geometrical model was created by Mimics13.0 based on CT data of T11~12 motion segment from one adult male,and then,the above models were imported into the Ansys11.0 for establishing the 3-D FE of anterior screw fixation on lower thoracic vertebra. The 3D FE models were further imported into Ansys11.0 and analyzed under 500N pressure loading on the upper surface of T11,and 10Nm torque loading for simulating thoracic axial compression,anteflexion,extension,lateral bending and rotation. The Von mises stress of screws and stick were recorded and analyzed statistically the difference of different stress distribution of the screws and stick. Results It was obviously that,the Von mises of the screw concentrated on the tail of screws,with the bigger stress at the inferior part than that at the superior part. Rotation movement resulted in breakage of the tails of screw and lower part of stick. Conclusions Anterior screw fixation system on lower thoracic vertebra will thicken the tails of screws and lower segment of stick. It is necessary to limit patients' activities by a waist-brace protection after operation.

In our previous work, we examined the improved transmit sensitivity of 2-D array transducers using multilayer PZT. In receive mode, the signal to noise ratio (SNR) requires a more complex examination. Typically, a coaxial cable connects a single layer element to a preamplifier at the scanner. In this configuration, the high impedance 2-D array element is unable to drive the coaxial cable and preamplifier efficiently. In addition to signal losses, the electronic noise from the preamplifier usually dominates the thermal noise of the transducer element which reduces the SNR. In this study, a 1.5-D 7.5 MHz array element was analyzed using the KLM model. We show the receive SNR increases by 8.7 dB compared to the control when a high impedance preamplifier is placed adjacent to the single layer transducer element. The receive SNR improvement combined with the transmit improvement using multilayer PZT yields an overall improvement of 23.7 dB. A 1.5-D 1 MHz hybrid array was fabricated and tested to confirm the simulation results.


Aiming at the features of satellite images and the need of meteorology researches and transactions, it is proposed here to utilize the existing image fusion technologies to fuse the meteorological satellite images. Two image fusion methods, wavelet transformation and HIS transformation, are used here. NOAA/AVHRR images and EOS/MODIS images are studied as examples. It is proven that wavelet transformation reserves the spectrum information completely, pinpoints the edge information of observed objects in meteorological satellite images, makes it easy to judge the category and altitude of clouds and is feasible to fuse the satellite images in different channels from the same sensor. HIS transformation combines the spectrum features of high resolution images and low resolution images, adds the images' spectrum features on the condition of reserving high resolution. So it is useful to identify the direction, area and detail information of object. This method is proven to be applicable to fuse the meteorological satellite images in different resolutions.

Objective: to investigate the interval time between surgeries and factors that can influence this process. Method: a quantitative, observational and cross-sectional study carried out in three surgical centers of a large-sized hospital in southern Brazil. Collection took place in January and February 2020, by observing the interval between script-guided surgeries. Data analysis was performed by means of descriptive statistics, correlation and factor analysis. Results: the mean turnover time was 37 minutes. The disassembly (r=0.540, p<0.001 and r=0.406, p<0.001), cleaning (r=0.584, p<0.001) and assembly (r=0.689, p<0.001) variables were positively and moderately related to turnover. The interval was longer with patients coming from hospitalization units than from outpatient services and, after minor surgeries, the time was shorter than in medium-sized and major surgeries. Conclusion: reflections on surgical center processes are provided. They will be useful in planning, implementing and managing this sector.


Background of the Study: Adolescence is the time between the commencement of puberty and the start of adulthood. Menarche is a significant occurrence in the lives of adolescent females because it is one of the signals that puberty has begun. Puberty is marked by a series of physical and mental changes.

Lake Pedder is important not just for its aesthetic, recreational, wilderness and biological values, but also for the intrinsic and scientific value of its landforms. This facet of the Pedder environment was never taken into account during the decision-making process prior to construction of the dams that inundated the area. The objectives of this paper are to provide an accessible documentation of those landform values, and to assess their geoconservation significance.


Now these days yoga therapy has been mostly used for the treatment of both somatic and psychic diseases. Yoga is one of the ancient Indian principles which rules over one's body and mind, by participating, it enable a person to attain peaceful and healthy life. The great saint Pantanjaly enumerated RAJAYOGA, which lays down an eight-fold path called EIGHT LIMBS OF YOGA, the third anga is called ASANA, Asana is defined as static posture. Thus yoga, a specific system of postures, will not only help to keep a person normal but also practiced to prevent and treat certain diseases.

The focus of this research is on human perception toward fire safety awareness in public hospitals. The perception was evaluated by looking at two variables, awareness, and knowledge. With the existence of knowledge and awareness, the perception of fire safety in hospitals is high. Thus, the three objectives are; i) evaluate and identify the relation of consumer perception towards the fire safety awareness in hospitals. ii) evaluate and analyse consumer perception on fire safety awareness with the effective value of designs and exit routes prepared. iii) suggest improvement measures in ensuring the hospital's occupants able to increase the awareness and understanding values in fire safety in hospitals. This study adapted quantitative methodology by using a random survey as an instrument which involved 285 respondents representing 6 selected hospitals in Malaysia. The findings found that there was no significant between the relation of awareness and knowledge with age, education, and occupation in identifying the level of awareness and knowledge in fire safety in hospitals. Yet, there was a significant value in gender which the men have higher awareness and knowledge as compared to women who were not significant in this study. Therefore, several improvement measures need to be done by the hospital administration to add awareness value among the hospital users.


For seismic physical modeling, piezoelectric transducers (PETs) usually are used as sources and receivers. Their properties affect data significantly, especially if data are processed as seismic data: (1) Strong resonance at one frequency causes a ringy signal and a narrow frequency band; (2) the pronounced directionality effectively limits the offsets at which energy arrives; and (3) because the dimension of the 12-mm transducer is larger than the wavelength (1.5 to 10.0 mm) , the recorded waveform changes with offset. To reduce the pronounced directionality of the transducers at ultrasonic frequencies, we designed PETs that have a smaller effective diameter than do traditional ones. To test their applicability for laboratory seismic profiling, we tested their frequency sensitivity, their directionality, and the change of waveform as a function of offset caused by their size relative to the wavelengths. The experiments showed that the PETs produce their best-quality data at frequencies of 350 to 550 kHz ...


Basically, double-slit device is intrusive wave detector. Shooting particles to study their properties is intrusion. It would not be the same as performing autopsy on tabletop. The difficulty is not only studying a particle in motion, but keeping it still is not any easier, if possible. We are incapable of identifying it's individuality. Particle is a mass of it's own entity, and wave is the reaction of it's complement. Above all, The rest of the universe is the absolute complement of an object. Even a particle, it is impossible for it to be anywhere else at the same time, since anywhere else is it's absolute complement.


Insects use biogenic volatile organic compounds (BVOCs) as chemical cues to find their host plants and colonize them. Studies of olfactory responses have reported that BVOCs released by host plants attract whiteflies. The citrus woolly whitefly, Aleurothrixus floccosus (Maskell) (Hemiptera: Aleyrodidae) is a serious foliar pest, infesting citrus orchards at the Pica Oasis, Tarapacá Region, Chile. We studied the attractant behavior of A. floccosus toward BVOCs emitted from lime (Citrus ×aurantiifolia (Christm.) Swingle), mandarin (Citrus reticulata Blanco), and tangelo (Citrus reticulata × Citrus ×paradisi Macfad.) shoots. We collected volatiles from living plants using dynamic headspace technique for 24 h. The BVOCs released by the Citrus species were collected on Porapak Q traps and analyzed by gas chromatography coupled to mass spectrometry (GC-MS). The chemical analysis revealed differences in abundances of monoterpenes, sesquiterpenes and aldehydes; thus, D-limonene (33.44%) was the most abundant compound in lime and significantly higher than mandarin and tangelo. On the other hand, sabinene (12.36%), nonanal (28.06%) and caryophyllene (22.97%) were more abundant in mandarin. Tangelo showed high abundance of β-phellandrene (17.01%), nonanal (17.87%) and caryophyllene (16.01%). In the two-choice bioassays, we found 13.5% and 17.1% more A. floccosus females in lime than in mandarin and tangelo, respectively. Our findings show that the volatile profile of 'Limón de Pica', C. aurantiifolia, elicits the strongest attractive behavior of A. floccosus females in the olfactometry experiments.

Abstract:"Cyclops" poses a challenge to readers as they try to navigate the narrative in Barney Kiernan's while negotiating the interpolations that appear throughout the episode. This essay argues for a way of reading the episode that considers the main narrative and the interpolations in a critical dialogue contesting nationalism. In addition, the study proposes a new way to understand the debate between David Hayman and Herbert Schneidau about when and where the episode is narrated and how it fits within the chronology of the novel's day. The concept of superposition from quantum mechanics provides a conceptual means to understand the narrative complexities of "Cyclops" without being reductive about their potential meanings. Superposition may also offer a way to understand Bloom's famous definition of the nation here.


Based on a yearlong observational study of participants in a "Live Action Role Playing" group called "Dagorhir," using the manhood acts perspective, we focus on how masculinity is constructed among low-status, subordinate men who self-define as "nerds." We demonstrate that through fantasy role-playing, men are given opportunities to increase their group status, while women are typically relegated to subordinate positions. Increasing status in Dagorhir involved a type of self-enhancement strategy that we termed "epic glory," which positioned men as social dominants. Epic glory was earned through training activities, at Dagorhir events, and through simulating dramatic death scenes. Such actions served as a performance of masculinity that was not possible for these men outside the role-playing experience. Importantly, women were excluded from many of the opportunities to enact epic glory, which helped reproduce inequalities both among males and between males and females participating in the events.

The most important characteristic of a GUI is that it provides the potential for giving users accessibility to many functions simultaneously. This leads to what has been characterised as multi-threaded or concurrent human-computer dialogue. As an alternative, consider the example of an automated bank teller. This is an application where users are constrained to a limited number of choices at each point in the dialogue. They may be able to choose between several services, cash, statement, new cheque book etc. but this choice is only available at a specific point in the dialogue. Such systems lead to very sequential human-computer dialogue. Concurrent accessibility is generally considered to be a good thing as it allows flexibility in the way users carry out their work and a good design principle is to maximise it, except where there are strong external constraints on the order in which tasks are to be carried out. The author outlines a method for describing and reasoning about the accessibility of functions when specifying a new product. This method encourages simultaneous accessibility to functionality. >


Background: Ectopic ureter is a congenital anomaly in which the final segment of one or both ureteral orifices is located distal to the bladder trigone. It may be classified as intra- or extramural. Surgical treatment of ectopic ureters in dogs is recommended and the approach varies with the classification. In the postoperative period, complications are common. When stenosis of the new ureteral ostium occurs, immediate repeated surgery is recommended. This study aimed at using the double J catheter placement following neoureterostomy to treat urethral obstruction secondary to the surgical treatment of an intramural ectopic ureter in a dog.Case: An 8-month-old female French bulldog with dysuria and urinary incontinence was seen at a private veterinary hospital in Jaboticabal, São Paulo. The patient had previously been diagnosed with an intramural ectopic ureter on the right side following imaging tests (ultrasound, computed tomography, and abdominal radiography, excretory urography) and had undergone neoureterostomy and closure of the intramural pathway approximately a year ago. Ultrasonographic examination showed dilation of the caudal portion of the ureter and hydroureter, which was suggestive of right ureteral stenosis. Computed tomography was also performed to evaluate the kidneys, ureters, and bladder; an increase in the diameter of the right ureter in its middle portion and close to the bladder triangle was observed. A new surgical intervention was indicated and performed. The ureteral route was identified in a region of the bladder trigone, incised, and probed with a urethral probe No. 04. The intramural course in the proximal urethra was identified and probed with a 16G epidural catheter. It was necessary to perform a neoureterostomy. A longitudinal incision (spatulation) of approximately 5 mm was made in the distal portion of the right ureter to increase the circumference of the anastomosis. The double J 4.7 French (Fr) catheter was inserted through the new ureter ostium into the bladder and advanced into the right kidney in a retrograde manner. Once the proximal end of the double J catheter reached the renal pelvis, the guidewire was withdrawn slowly to allow the catheter to bend in the areas of the renal pelvis and the trigone. The distal end of the double J catheter that extended beyond the bladder lumen was sectioned for better bladder closure. The patient underwent clinical evaluation and laboratory tests (complete blood count and serum creatinine concentration, urine test with bacteriological culture and susceptibility test) 2 weeks after the procedure and, subsequently, every 3 months. Ultrasonography of the urinary tract was performed every 2 months.Discussion: We used a double J catheter in the patient due to a previous obstruction of the ureter ostium after the first surgical procedure. In this way, complications such as postoperative obstructions due to ureteritis and ureteral constriction were avoided and ureteral anastomosis was facilitated. It has been reported that animals subjected to ureteral stent placement have high incidences of dysuria and urinary tract infection, and low incidences of stent migration and occlusion. In this case, no signs of occlusion or obstruction of the implant were identified, but there was a recurrence of urinary tract infections. These frequently cause urethral obstruction associated with the healing of the new ureteral ostium. Patient follow-up and findings associated with the long-term insertion of the double J catheter provide support for the clinical relevance of the present report.

The new features of IA-64 SIMD instructions make it difficult to map the semantics of machine instructions to higher-level intermediate representations, which is the key problem to binary reverse engineering. This paper presents an effective approach to semantic mapping of IA-64 SIMD instructions, improving existing technologies in two aspects. Our techniques extend the syntax of existing SSL according to the new features of IA-64 architecture and add new algorithms to meet the demand of mapping the semantics of some complicated SIMD instructions. Finally, the relevant techniques are evaluated by a set of programs from the Berkeley multimedia workload with a static binary translator from IA-64 to Alpha. The preliminary results show the originality and effectiveness of the approach


This paper presents a study of POL-inSAR coherence statistical behavior. A derivation of optimal coherence distributions show that these widely used indicators are indeed affected by a complex bias structure. The formulation of the coherence information using a multidimensional speckle reveals that classical and optimal coherences are not affected by the same form of bias. This conclusion is tested over a natural scene POL- inSAR data set.


This paper discusses the recent and future operational performance of the Russian electricity-generation industry, which is central to government plans for industrial regeneration and environmental improvement. The paper commences with information on outputs from the industry, namely current and future production levels, and atmospheric emissions, followed by data on fuel and capacity inputs. Information is then presented to show that the meeting of future output targets may run counter to objectives for reduction of greenhouse gas emissions, in view of the slow replacement of ageing plant and the plans to switch fuel from natural gas back to coal. The paper then discusses the economic and commercial factors influencing the strategic choices available to the Russian power-generation industry and the barriers to the implementation of these alternatives. The conclusion is reached that substantial investment is required in Russian power stations, which may require significant increases in electricity prices with associated economic and social problems for industrial and domestic consumers. The pricing system could also be used to reduce demand to match the capacities of available equipment, but that decision may also give rise to associated economic and social problems.

—Image registration is a key, essential element in analysis of Remote sensing images. Registration is critical both for initial processing and for end-user processing of those image products for data fusion, and change detection. This paper focused on the feature-based category of image registration algorithms. Many techniques for the detection and description of images' local characteristics have been proposed to register a set of images without user intervention. However, it is unclear which descriptors are more appropriate. The descriptors should be distinctive and at the same time robust to changes in viewing conditions as well as to errors of the sensor. In our evaluation, we have separated the detector from the descriptor as their performance depends on the interest point detector used. The descriptors are compared according to their recall and runtime efficiency and this deals with several geometric and photometric changes. We also propose an extension to the SURF descriptor and the results show the effectiveness of proposed improvements compared to base SURF method. Furthermore, we observe that the SURF descriptor outperforms the others' descriptors. Finally, based on the test results, we propose an approach to register automatically remotely sensed images.


Supervised machine learning generally requires pre-labelled data. Although there are several open access and pre-annotated datasets available for training machine learning algorithms, most contain a limited number of object classes, which may not be suitable for specific tasks. As previously available pre-annotated data is not usually sufficient for custom models, most of the real world applications require collecting and preparing training data. There is an obvious trade-off between annotation quality and quantity. Time and resources can be allocated for ensuring superior data quality or for increasing the quantity of the annotated data. We test the degree of the detrimental effect caused by the annotation errors. We conclude that while the results deteriorate if annotations are erroneous; the effect – at least while using relatively homogeneous sequential video data – is limited. The benefits from the increased annotated data set size (created by using imperfect auto-annotation methods) outweighs the deterioration caused by annotated data.

Publications are among AGU's main products, and for most AGU members, published papers are the goals of their scientific endeavors. While we have watched the numbers of published pages grow and the journals multiply, we have rarely studied other aspects of our publications in a statistical fashion. In an attempt to learn which groups financially support the research reported and to learn something about the authors, we examined the acknowledgments and authors' affiliations in each papers of AGU's seven scientific journals for the calendar year 1986.

The source of funding was assumed to be the agency acknowledged in the paper. For each journal, we identified whether one of the U.S. government agencies, a U.S. university, a private U.S. group, or a non-U.S. group provided the financial support. The results are shown in Table 1, where the body of the table shows the percentage of total acknowledgments for each journal.


Experimental fault-injection plays a key role in the process of fault tolerance validation. In this paper we discuss the limitations of conventional experimental setups and investigate how highly complex FPGAs can aid in overcoming these. Based on a thorough analysis of the potential aims of fault-injection experiments we derive a set of conditions for the design of an FPGA-based fault-injection toolset. We present the fault-injection tool FIDYCO as an example implementation of this concept. Our FPGA-based toolset has three main advantages: First, the availability of a physical target system allows to perform experiments in real time. Second, the programmable nature of the FPGA target platform facilitates controllability and observability comparable to that of simulation-based approaches. Third, the tight integration of fault injector and device under test on the same hardware platform allows for a higher precision of fault injection and diagnostic resolution.


The aim of this work is to provide an upper bound on the eigenvalues counting function $N(\mathbb{R}^n,-\Delta+V,e)$ of a Sch\"odinger operator $-\Delta +V$ on $\mathbb{R}^n$ corresponding to a potential $V\in L^{\frac{n}{2}+\varepsilon}(\mathbb{R}^n,dx)$, in terms of the sum of the eigenvalues counting function of the Dirichlet integral $\mathcal{D}$ with Dirichlet boundary conditions on the subpotential domain $\{V< e\}$, endowed with weighted Lebesgue measure $(V-e)_-\cdot dx$ and the eigenvalues counting function of the absorption-to-reflection operator on the equipotential surface $\{V=e\}$.


The optimum conditions for formation of ion associate (IA) of molybdophosphoric heteropolyacid (GPА) with basic blue K (OCK) in water solution and in solid phase of KY-2×8 were studied. It is determined that optimal conditions for IA formation in the solution are next: СHNO3 = 0.4 mol/L, СNa2MoO4 = 9.6∙10 –4 mol/L, Cock = 2∙10 –3%. The Beer's law is obeyed in CP = (0.8–3.2)∙10 –5 mоl/L with Сmin(Р) = 8.06∙10 –6 mоl/L. It is demonstrated that OCK adsorption isotherm on KY-2×8 has L-type with аmax = 1.67∙10 –5 mоl/g and adsorption constant kock = 2.55∙10 5 L/mоl. Maximum capacity (аmax = 0.32·10 -5 mоl/g) of OCK-KY-2×8 towards GPA is reached at the same acidity as it is in solution, but at much lower (9.6∙10–5 mol/L). Adsorption isotherm of GPА is Ltype. For phosphorus adsorption from 50–1000 ml solution on 0.3 g of adsorbent, the distribution coefficient is Dmax = 3.83∙10 4 ml/g. Сmin(P) = 8.06∙10 –7 mоl/L. The Beer's law is obeyed in interval CP = (0.08–6.45)∙10 -5 mоl/L. For determination of 25 μg of phosphorus in solution 103-fold of K, Na, Ca, Mg, Cu, Zn, Co, Ni, Cd, Pl, Al, Tl, In, Ga, Ge, Nb, Ta, V, B ions has do influence. The influence of silicon is diminished by regulation of acidity.

The study aims at analyzing the stress state of the human skull with FEA, simulating the loads due to the insertion of rapid palatal expanders with two or four arms. A 3D CAD solid model of a human skull has been created starting from CT slices. Using FEA, forces that simulate the loads developed by the expander have been applied to the solid model of the skull to determine the stress state.


In teaching learning process, the target language is an important thing which has been noticed by the teacher. The phenomenon about misunderstanding language is not only occurring in daily life with soft conversation but also in the formal education. In education event, when the teacher teaches students in the classroom, they use target language during activities. The aims of this study were to describe the teacher's hurdles in using target language at first grade of Junior high school and how the teacher delivered instruction by using target language at EFL class. This study used a descriptive qualitative approach. This study used a qualitative description. Five English teachers were involved. The researcher collected the data as interview, and observation. Referring to the finding of the study, based on result of interview found the teachers problems used target language in teaching learning process, such as; the low vocabulary of the students, the ability of English skill of the students, the situation in the classroom did not support the use of target language, the time was not effective. Based on the findings of classroom observation in classroom the teacher delivered used the target language in simple sentence on greeting, giving instruction, asking question, delivering materials and closing.


The reliable evaluation of simulation data of a virtual vehicle, with respect to the comfort felt by a user, is of great interest because it enables a pre-optimization of construction parts at a very early stage of the product development process and therefore economizes development time and costs. For this purpose, evaluation models are necessary that allow a calculation of subjective comfort ratings from objective characteristic quantities. Besides the standard method of modelling by regression, artificial neural networks (ANN) are a very promising tool for predicting subjective comfort ratings on the basis of objectively measurable quantities. On the example of the automated start-up procedure, evaluation models are developed and applied by means of multiple linear regressions and feed-forward back propagation networks. The basis for the modelling are drive tests with laymen evaluators in a test vehicle especially built for this purpose, with start-up properties which can be varied in the customer-relevant range. The comfort rating is realized with an evaluation scheme suitable for laymen evaluators. By means of a performance index based on the comparison of calculated and real comfort values determined in the drive test, a check of the models concerning approximation and prediction quality is carried out. Furthermore, guidelines are determined that deal with the effective application of ANN for the objectification of comfort ratings that are transferable to similar problems. Among others, measures are demonstrated that prevent a "memorizing" of the training data and the consequent loss of generalization ability. By comparing the methods, it can be established that the ANN are superior to the regression models with respect to prediction accuracy. It is shown that the evaluation from the customer's point of view can be applied for real as well as for virtual (simulated) start-up procedures. As a result, it is possible to achieve estimations beyond those of the comfort properties of real start-up procedures, a fact which makes the application effort more manageable, especially for start-up systems. It is also possible to estimate the comfort for virtual vehicles at an early state of the product development process. This represents a significant element for the reduction of development time and costs by means of virtual methods, and at the same time increased customer acceptance. 2 Albers / Albrecht 2002, 2003a, 2003b, 2004a, 2004b, 2005
