This paper discusses the methodology developed for petrophysical modeling and its application to the main limestone formations in the Mid-region of Iraq. The systematic approach presented in this study evaluates not only combination of porosity, permeability and irreducible water saturation at each depth, but also free-water level and capillary pressure curve, such that water-cut of flow tests is closely reproduced in numerical simulation. It is one of the major achievements in this study. The algorithm matched to several sets of core samples: 2,903 porosity, 2,767 permeability, and 95 Irreducible water saturation samples that give the algorithm the robustness for future properties prediction. To develop the prediction Algorithm, it was employed multiple regression analysis (MRA) which mathematically requires independence between explanatory variables. Since possible explanatory variables (porosity, permeability and facies) indicate interdependency, it was investigated when necessary to transform the variables into independent axes. It was found that logarithm of permeability has correlations positive to porosity and FZI and negative to irreducible water saturation. Therefore, foot-by-foot evaluation shall meet the following conditions, (Sw) along wells shall be explained by single free-water level (FWL) for each pressure compartment and Water-cut observed on production test shall also be closely simulated with the FWL, For modeling purposes, Sw is split into irreducible water saturation (Swir) and transitional (mobile) water saturation (Swm) as water-cut is a function of only the latter.


Original scientific paper We present a methodology for dispatching trains which prevents deadlocks and includes possible limitation of the available energy provided by the power supply. Our approach applies Kronecker algebra to manipulate matrices. Generally blocking of trains occurs due to a lack of some resource which can be either infrastructure or energy. Our method can also be used to calculate travel times in a rough way. Thereby blocking time is included in the calculated travel time. To model the movements of trains in a railway system we use graphs, which are represented by adjacency matrices. We assume that the edges in a graph are labelled by elements of a semiring. Usually two or more distinct train route graphs refer to the same track section to model synchronization. Our approach can be used to model a complex railway system. For example, if additional trains have to be scheduled, power stations or interconnection lines fail or are not available due to maintenance, our model can be used to calculate the impact on the travel times of the trains in the system.


ABSTRACT Sexual assault on university campuses is a pervasive problem that affects approximately 25% of female students and has wide-reaching negative outcomes [DeKeseredy, W., and K. Kelly. 1993. 'The Incidence and Prevalence of Woman Abuse in Canadian University and College Dating Relationships.' The Canadian Journal of Sociology 18 (2): 137–59; Krebs, C. P., C. H. Lindquist, T. D. Warner, B. S. Fisher, and S. L. Martin. 2009. 'College Women's Experiences with Physically Forced, Alcohol- or Other Drug Enabled, and Drug-Facilitated Sexual Assault Before and Since Entering College.' Journal of American College Health 57 (6): 639–49]. It is important that universities develop and implement comprehensive policies and procedures to address this complex issue. This research explores sexual assault-related policies (N = 119) at all public universities in Canada (N = 72). We examine four elements suggesting comprehensiveness of a university's sexual assault response (policy comprehensiveness, availability of campus support resources, and sexual assault information webpage presence and comprehensiveness), and test whether these elements are related to various institutional features. Results show significant differences related to university characteristics across the measures of comprehensiveness, and indicate a need for increased focus at the institutional level to ensure that policies are sufficiently comprehensive to handle the complexities that arise in sexual assault cases.


102.30 A surprising 3-D result involving a hexagon In a recent posting (June 2017) on Facebook, the first author presented a relatively unknown theorem regarding the concurrency of lines connecting the midpoints of the opposite sides of a plane hexagon with opposite sides parallel, but not necessarily equal (see [1]). To prove this theorem, it was necessary to employ projective geometry methods as using simple Euclidean methods do not suffice. In response to this posting, John Berry (a mathematical friend for many years from York, UK) asked the question on Facebook whether this result would also be true in 3-D space. Obviously these lines will be concurrent for a spatial 3-D hexagon with opposite sides equal and parallel as the concurrency follows immediately from the joint central point of (reflective) symmetry of the three parallelograms formed in space. However, the question arose whether one could construct a spatial hexagon with opposite sides parallel, but not equal. Experimentally exploring this possibility using the dynamic 3-D software Cabri 3D by construction and measurement (e.g. [2]), it turned out much to our surprise, that in 3-D space, if a hexagon has three pairs of opposite sides parallel, then they are equal also. This seemed rather counter-intuitive to us as we had expected to be able to produce a 3D analogue to a plane hexagon with opposite sides parallel, but not necessarily equal, especially since one normally has more degrees of freedom in space. Below is presented a Euclidean proof of this result and its point (reflective) symmetric property (as described below), followed by a vector proof. A


In 1613 the learned divine Dr Andrew Willet remarked on the number of London churches that had recently been rebuilt, commenting that 'generally all of them have beene more Beautified and adorned in the space of twenty or thirty yeeres than in an hundred yeeres before'. It is somewhat surprising, then, that the subject of church building in Jacobean London has attracted little attention. Yet the detailed examination of such building provides special insight into the way parishioners viewed themselves and their community.

In recent years online social networks have had a great impact in the way people communicate and share information, however this social networks are based on internet, security and trust are a big concern due the nature of the information so that this information have security restrictions and privacy. The present study searched by an exploratory factor analysis what factors are the most


The current conditions of instability and the need for constant adjustment of economic development strategies have led to an increase in the likelihood of unpredictable results that can adversely affect the enterprise. In this regard, situations arise that can cause losses and create unforeseen dangers. The social sphere, constitutes the country's labor potential in Ukraine, is one of the least protected and prone to risk. Activities to ensure social security is an element of a complex system – state policy as a whole and its segment such as ensuring national security, involves the development of measures and the implementation of actions aimed at ensuring and protecting the rights of individuals and social groups. The article analyzes the possible risks in the heavy industry that may violate social security, gives recommendations, quantitative methods for calculating risks. The current problems in industry (low mobility and the high cost of changing technology) and the influence of external and internal factors that increase the likelihood of negative and emergency situations on effective economic indicators are considered. The current state of social security in Ukraine is analyzed and incentives for the development and implementation of safer technological systems and risk reduction in the industry are identified.
It is revealed that attracting investment in the industry, which will increase the product line, improve product quality and working conditions, transparent use of funds can significantly reduce the risks of changing technologies and cheaper products, and an increase in wages and social guarantees will positively affect the preservation of labor potential countries.


Traditional Wacker-type oxidations of unbiased alkenes produce ketones as major products. Recently, Grubbs' group reported a Wacker-type oxidation system in which aldehydes (rather than ketones) have been generated predominantly in the presence of a nitrite co-catalyst. To elucidate the mechanistic origin of the aldehyde selectivity, density functional theory (DFT) studies have been conducted in this study. Two oxymetalation pathways, i.e., syn addition and anti addition pathways, were considered for various possible active species including monomeric Pd, bimetallic Pd–Pd, heterobimetallic Pd–Cu, and heterobimetallic Pd–Ag complexes. It is found that syn addition is kinetically more favored than anti addition in general. Meanwhile, the most feasible oxymetalation processes occur on the heterobimetallic Pd–Cu complexes. Investigations on the subsequent aldehyde formation process show that 1,2-H shift mechanism on tBuOH-ligated Pd–Cu complexes is superior to the betaH-elimination mechanism. Besides, the 1,2...


Purpose:  Antiepileptic drugs (AEDs) are widely used not only in the treatment of epilepsy but also as treatments for psychiatric disorders. Pharmacoresistance of AEDs in the treatment of epilepsy and psychiatric disorders is a serious problem. Transport of antiepileptic drugs by P‐glycoprotein (Pgp, ABCB1, or MDR1), which is overexpressed in the blood–brain barrier, may be a mechanism for resistance of AEDs. For most AEDs, conflicting evidence precludes consensus on whether they are substrates of Pgp. The objective of this study was to evaluate whether analogs and metabolites of the AED carbamazepine are substrates of human Pgp.


A reduced physical model of the integral non-linearity error in high resolution R-2R D/A converters is obtained by circuit analysis and application of the ambiguity algorithm. Field experiments demonstrate that functional test programs based on this model achieve shorter test times and lower prediction errors than those based on larger models obtained by straight QR factorization.<<ETX>>

Writers have long been preoccupied with objects, real or imagined — from Aladdin's lamp to Pandora's box to the Pulitzer Prize-winning ekphrastic novel The Goldfinch (Tartt 2013), about the painting of the same name. In the eighteenth century, this preoccupation with objects manifested in a genre called it-narrative, stories that have object (or animal) narrators or are about non-human characters. Writers used animism, a worldview where the material universe possesses a metaphysical essence and nonhuman entities have spirits, as a narrative technique to bring these objects to 'life'.; Submitted in the fulfilment of the requirements of the degree of Doctor of Creative Arts, University of the Sunshine Coast, 2017.


"?jyyhy this policing of the territory of knowledge?" (Felman 181) Shoshana Felman vtr asks this question in some exasperation as she observes a censorious tendency at work in some writing on trauma and trauma studies. She should not be so surprised, however, since knowledge is one of the central issues of trauma studies as it has developed in recent years. As Felman puts it, referring to Cathy Caruth, "the event of trauma destabilizes the security of knowledge and strikes at the foundation of the institutional prerogatives of what is known" (181). To respond to trauma is to experience as ethically urgent the questions of who knows and what is known, of who can speak with authority and what can be communicated in intelligible form. In particular, the nature and status of psychoanalytic knowledge is at stake here, given the pivotal role that psychoanalysis has played in the elaboration of trauma studies. Psychoanalysis has sometimes been characterized and caricatured as the pursuit of sexual secrets underlying obsessive behavior. But trauma, understood as the disruption of knowledge, upsets the masterful position of the analyst, who was famously described by Lacan as the subject supposed (but only supposed) to know. This article examines the problem of posttraumatic knowledge first by reviewing recent controversy over the psychoanalytic underpinning of trauma studies, and then by looking at two texts which explicitly stage and explore the psychoanalytic analysis of traumatic survival. The first is Elie Wiesel's novel Un desir fou de danser (2006), in which a troubled man undertakes a course of psychoanalysis, both rejecting his analyst's search to uncover hidden secrets and yet reluctantly conceding the pertinence of her insights, until the course is terminated by the analyst herself. The second work is Le Savoir-deporte: Camps, histoire, psychanalyse (2004), a collection of texts by the Auschwitz-survivor and Lacanian psychoanalyst Anne-Lise Stern. Angered by the failure of psychoanalysts to heed the effects of the camps on post-war generations, she attempts to sketch what she calls le savoir-deporte, a mode of knowledge formed by the camps rather than a dispassionate interpretation of deportees' experience. The article suggests that in Wiesel's writing there is a fascinated but determined resistance to psychoanalysis, whereas Stern's work enacts a resistance within psychoanalysis to the appropriation of the survivor's experience. Coming from very different positions, both Wiesel's novel and Stern's essays converge as they point towards a mode of post-traumatic knowing. It would be hard to overrate the importance of Cathy Caruth' s work on the development of psychoanalytically-informed trauma studies in the humanities. Describing her as the "most authoritative, most original interdisciplinary theorist" of the


With more complex partitioning structures in recent generations of video coding standards, the computation complexity of video encoder for partition block size search has been increasing drastically. To expedite the overall encoding process, it is desired to make faster partitioning decisions without much compression performance degradation. In this paper, we propose a multi-scale multi-stage machine learning(ML) based framework to accelerate partition block size search. The framework includes a collection of ML models, each dedicated to make a simple decision for a particular block size at a particular stage during the partitioning rate-distortion optimization(RDO) process. The ML models can predict whether the RD evaluation of certain partition block sizes can be skipped, saving unnecessary computation in the encoder. The proposed approach is implemented and tested on VP9 with the open source library libvpx. Significant encoding speed improvement has been observed with neglectable compression performance regression. The framework and methodology can be easily applied to other video codecs and implementations as well.


The temperature of the maximum density (TMD) of aqueous solutions was measured for twenty complex ions of transition metals. From the degrees of depression of TMD, Despretz's constant kionD and the constant of excess depression of mixing Δkion were determined. These constants along with Bion coefficient of viscosity give us information on the structure of water in the vicinity of ions. [Co(H2O)6]2+, [Ni(H2O)6]2+, [Cu(H2O)6]2+, and [Zn(H2O)6]2+ are electrostrictive structure-breakers in the natural order of Irving-Williams, Co(II) Zn(II). Of the complexes [Co(NH3)6]3+, [Co(en)3]3+, and [Co(pn)3]3+, the pn-complex is the strongest hydrophobic structure-maker due to the hydrophobic nature of its aliphatic constituent. Both [Fe(CN)6]3− and [Co(CN)6]3− are fairly strong electrostrictive structure-breakers, while [Fe(phen)3]2+, [Co(phen)3]2+, and [Co (phen)3]3+ are clathrate-like structure-makers. The EDTA and CyDTA complex ions of Co(II), Ni(II), Cu(II), and Zn(II) show no significant difference ...


We present a global data set of free tropospheric ozone-CO correlations with 2 × 2.5 spatial resolution from the Ozone Monitoring Instrument (OMI) and Atmospheric Infrared Sounder (AIRS) satellite instruments for each season of 2008. OMI and AIRS have near daily global coverage of ozone and CO respectively and observe coincident scenes with similar vertical sensitivities. The resulting ozone-CO correlations are highly statistically significant (positive or negative) in most regions of the world, and are less noisy than previous satellitebased studies that used sparser data. Comparison with ozone-CO correlations and regression slopes (dO3/dCO) from MOZAIC aircraft profiles shows good general agreement. We interpret the observed ozone-CO correlations with the GEOS-Chem chemical transport model to infer constraints on ozone sources. Driving GEOS-Chem with different meteorological fields generally shows consistent ozone-CO correlation patterns, except in some tropical regions where the correlations are strongly sensitive to model transport error associated with deep convection. GEOS-Chem reproduces the general structure of the observed ozone-CO correlations and regression slopes, although there are some large regional discrepancies. We examine the model sensitivity of dO3/dCO to different ozone sources (combustion, biosphere, stratosphere, and Kim, P. S., D. J. Jacob, X. Liu, J. X. Warner, K. Yang, K. Chance, V. Thouret, and P. Nedelec (2013), Global ozone-CO correlations from OMI and AIRS: constraints on tropospheric ozone sources, Atmos. Chem. Phys., 13, 9321-9335, doi:10.5194/acp-13-9321-2013. 11 lightning NOx) by correlating the ozone change from that source to CO from the standard simulation. The model reproduces the observed positive dO3/dCO in the extratropical northern hemisphere in spring-summer, driven by combustion sources. Stratospheric influence there is also associated with a positive dO3/dCO because of the interweaving of stratospheric downwelling with continental outflow. The well-known ozone maximum over the tropical South Atlantic is associated with negative dO3/dCO in the observations; this feature is reproduced in GEOS-Chem and supports a dominant contribution from lightning to the ozone maximum. A major model discrepancy is found over the Northeast Pacific in summer-fall where dO3/dCO is positive in the observations but negative in the model, for all ozone sources. We suggest that this reflects a model overestimate of lightning at northern mid-latitudes combined with an underestimate of the East Asian CO source.

Environmental disclosure (ED) is now considered to be a 'key' medium through which to communicate a corporations 'environmental' performance to its stakeholders. The rapid growth of 'Internet' technology has created the ability for firms to 'disseminate' information to the 'global' audience by removing all 'geographical' barriers. In this study, we explore the status of ED made by 39 corporations during the year 2005-06, by using "content" analysis methodology. In order to examine the quality of ED by these corporations on their Websites, we followed Technology Adoption Model. The empirical data used in this study is based on the online Annual Reports, and disclosure made on their Websites. A careful analysis of the information collected indicates that corporations provide more ED on their Websites, in sharp contrast, to reporting made within their Annual Reports. Fortunately, most of the corporations making ED on their Websites consider 'environmental' information to be 'very' significant to the 'visitors' of their Websites. However, ED in Annual Report is general, broad and narrative in nature, without specifically discussing the "environment management policy" followed by the corporation and/or "statement of assurance" from the corporate management regarding compliance with the external standards, if any. We feel that this needs to be improved soon, since narrative comments do not reflect the contribution of the corporation towards the betterment of the environment. However, corporations are still adapting ICT, and as yet, do not fully exploit all of its capabilities. Thus, there is considerable scope for corporations to improve their Internet- and Web-based corporate EID.


Type 1 diabetes mellitus affects bone turnover by i nterfering with the normal functions of bone cells. Osteoblasts seem to partic ipate to both bone formation and resorption. Their direct bone resorptive effect was discovered recently as osteoblasts were proved to secrete cathepsin K, a lysosomal protease which represents the major cysteine cathepsin in osteoclast and is responsible for bone resorption by digesting the organic extracellular matrix of bone. Purpose: Our aim was to explore osteoblast secretion of products involved in bone formation and resorption, in particular of a bone formation enzyme, alkaline phosphatase and a bone resorption enzyme, cathepsin K and to further evaluate if the secretion of these enzymes is influ e ced by diabetic conditions by testing the effects of different glycemic concentrations on human primary osteoblastic cell cultures. Materials and methods: Primary human osteoblastic cell cultures were obtai ned using femoral head trabecular bone from patients wi h h p arthroplasty. Third passage subconfluent osteoblasts were exposed for 36 hours t several glucose concentrations: 2.8 mmol/l (hypoglycemia), 5.6 mmol/l (normoglycemia), 11.1 mmol/l (moderate hyperglycemia) and 28 mmol/l (extreme hyperglycemia ). Cathepsin K and alkaline phosphatase activities were measured from cell supe rnatants. Results: Alkaline phosphatase activity values ranged between 65.67 ± 9.29 U/l in extreme hyperglycemia and 74.33 ± 13.61 in hypoglycemia group. The differ ence between groups was tested and a p-value of 0.806 was obtained. The lowest catheps in K activity was observed in moderate hyperglycemia group (31.04 ± 0.73 pmol/l) and highest in hypoglycemia (35.51 ± 6.97 pmol/l). There existed no significant differ ence between groups regarding cathepsin K activity (p=0.671). Weak inversely prop ortional correlations were found between glucose and alkaline phosphatase and cathep sin K levels respectively. A significant association was observed between alkali ne phosphatase and cathepsin K. Conclusions: Our study sustains the secretion of cathepsin K by osteoblasts and concludes that short time exposure (36 hours) to hi ghor low-glucose medium seems to have no significant impact on alkaline phosphatase and cathepsin K activities in human osteoblastic cell cultures. It is the first researc h that studies the effects of glucose on osteoblast-secreted cathepsin K. Further studies ar e w ranted to complete information on the matter.

Background: This study examined undergraduate MBBS and nursing students' quality of life with internet addiction and the association of anxiety and stress. Aim: We aimed to partially replicate the participant's online activities, changes in behaviour by internet addiction, quality of life when internet access was not possible and frequency of internet use. Materials and Methods: A cross-sectional study was applied in included university involving 400 MBBS and nursing students. World Health Organization Quality of Life-BREF Questionnaire (WHOQOL-BREF) scale for assessment of the personal quality of life. Scores of internet addiction test, Beck Anxiety Inventory and WHOQOL-BREF were compared by using the Mann–Whitney test or Kruskal–Wallis test. Results: The main findings revealed various risk factors associated with internet addictions, such as psychological distress, anxiety, mood disorders, suicidality, aggression, stress and sleep problems. Most of the intervention studies used an invariant behavioural therapy approach, although other interventions appeared effective in reducing addiction symptoms. Conclusion: Based on the students' addiction finding of an association between quality of life with internet addiction and anxiety and stress problems across combination with high prevalence rates amongst adolescents and university students, the individuals will use these tools. The implication of these findings is further discussed, and research is needed to develop and implement prevention strategies and treatment offers.


Image reconstruction is a method by which the underlying images, hidden in blurry and noisy data, can be retrieved. This is used in applications such as computer tomography (CT), magnetic resonance and radio astronomy. In recent times, a non-parametric adaptive regression method called steering kernel regression was proposed and proved to be effective. This method involves computation of local gradient at each pixel thereby making it computationally intensive. The time consuming parts of the steering kernel regression can be optimized by off-loading them onto GPUs and multi-core processors. The parallel implementation of this algorithm improved the performance of image processing applications such as denoising, deblocking and upscaling. It has given an average speedup factor of 6 on multi-core and 21 on a GPU.


A tuberculosis associated Paradoxical Reaction (PR), aka tuberculosis associated immune reconstitution inflammatory syndrome (TB-IRIS) is defined as the worsening of clinical or radiological findings, following the initiation of appropriate antitubercular treatment, in the absence of evidence of disease relapse or any another probable diagnosis. PR is not uncommon. It is reported in up to 35% of immunocompromised patients with HIV co-infection and in fewer than 5% of immunocompetent patients. We are presenting a case of PR in an immunocompetent host, who is an internal medicine resident, discussing the entity and also highlighting the occupational health hazards in health care workers (HCWs).

There exists very fine correlatively and leaner equations between changes of the observed hemorheolgical variables produced by these two antihypertensive agents.


: To analyze the clinical efficacy of finger points combined with anisole encapsulation in rapid recovery after gynecologic surgery. Forty patients who underwent gynecological surgery in our hospital from August 2021 to August 2022 were selected, and the patients were divided into control (n = 17) and treatment (n = 23) groups according to the random number table method. In the control group, patients were given conventional treatments, including early postoperative water intake, feeding, early removal of urinary tubes, and active double lower extremities. Treatment groups were given the patients finger points combined with anisole encapsulation treatment on the basis of the control group. Patients in both groups were analyzed for improvement in clinical symptoms, pain at various time periods after surgery, postoperative rehabilitation, satisfaction with treatment, and effectiveness rates. Time to recovery of bowel sounds, time to flatus, time to defecation, time to disappearance of abdominal pain due to abdominal distension, and hospital stay were shorter in the study group compared with the control group (P < 0.05); The VAS scores of the treated patients were lower than those of the control group at 12 h after surgery (P > 0.05) in both groups, and


Investigations to reduce the friction and improve the dynamic performance of a self-acting air foil journal bearing have been performed and presented herein employing the texture, micro-groove and micro-pocket on the top foil. Significant improvements in the static and dynamic performances have been found in presence of micro-pocketed/grooved and textured top foils in comparison to conventional plain foil. The micro-pocketed top foil yields better performance as compared to textured and conventional cases. In the presence of micro-pocket on top compliant foil, the bearing yielded a significant reduction in friction coefficient varying in the range of 8%–11% as compared to conventional one. Moreover, better dynamic stability has also been found even at lightly loaded conditions in the presence of texture and micro-pocket.


Objective: The focus of this investigation is to study the motivations of people who participate as volunteers in the community dining rooms of the State of Mexico, and based on solidary actions and cooperation, how social relationships between people involved in community dining rooms are built, as volunteers or dinners is analyzed. Methodology: The study takes place in several community dining rooms in the State of Mexico. Voluntary participation in community dining rooms was studied from the social constructionism perspective. This was considering the categories of volunteer motivation and using qualitative tools such as semi-structured interviews and a questionnaire with open-ended questions with the objective of ascertaining what motivates people who participate voluntarily and as well as the relationships of social solidarity for social construction and reconstruction, from an actor centered perspective. Results: The present work clearly identifies a proactive and pro-social voluntary participation of people who need to feed their family, but, at the same time, this is an act of solidarity and generosity because of the interest in social welfare and feeding of people who need it. Limitations: Motivations compete with the alimentary needs that families have to face and the difficulties of participation without pay in community dining rooms may promote their dependence and increase their vulnerability. Conclusions: An actor-oriented perspective indicates the need to understand the motives of voluntary participation in community dining rooms and how volunteering becomes a part of everyday life of the people involved. Furthermore, this perspective allows analysis of social practice and discourse carried out and interpreted by social actors, therefore enabling the consideration of small-scale social interaction scenarios as a pool of resources and relationship networks.


Thermal decomposition processes of two types of Barzas sapromixites - a tile-like modification ("tile") and a product of its weathering ("exfoliated tile") - have been investigated in various media (air and helium). It has been shown that in the course of temperature-programmed decomposition (10 °C/min) of these forms of tile-like Barzas sapromixite, in both oxidizing (air) and inert (helium) atmospheres, four main temperature ranges can be distinguished: 1) < 150 °C - removal of adsorbed water (this temperature region is more pronounced for the weathered form of tile-like Barzas sapromixite); 2) 150-350 °C - removal of low molecular weight volatile components of coal in helium environment (with their simultaneous ignition in case of the decomposition in air); 3) 350-550 °C - the temperature region of primary or fast coal pyrolysis in an inert medium; in an oxidative medium, this stage of pyrolysis is accompanied by the burning of released tarry substances; 4) > 550 °C - the temperature region of secondary or high-temperature coal pyrolysis to form semi-coke in helium atmosphere, or the region of burning this semi-coke in air medium. Thermal breakdown processes of "exfoliated tiles" in the temperature range of the most intensive decomposition (350-550 °C) have been found to require less energy consumptions than the similar processes for tile-like Barzas coals (by 72-73 kJ/mol for both gas media of thermal treatment). It is supposed that the differences observed in thermal behavior of Barzas sapromixite forms under investigation may be related to the different contents of mineral components and their effects on the thermal decomposition of coal organic matter.

PURPOSE: A portable fluorescence detecting system is provided to enhance detection efficiency by using a reflective surface of a curved surface and an LED excited fluorescence materials without using a lens and laser. CONSTITUTION: A portable fluorescence detecting system comprises a light source(100), a rotating unit(300), a replaceable filter(200), a curved reflector(400), and an optical detector(500). The replaceable filter excites lights emitted from the light source and is installed in one lateral surface of the rotating unit. A mirror in an inner surface of the curved reflector is formed into a curved surface form. The light source is installed in a constant area of the exterior of the curved reflector. Fluorescence materials of a specimen(600) are excited by the lights generated in the light source so that the optical detector detects optical signals generated by the excitation of fluorescence materials. The optical detector converts the optical signals into electric signals.


The Wiener index of a network, introduced by the chemist Harry Wiener, is the sum of distances between all pairs of nodes in the network. This index, originally used in chemical graph representations of the non-hydrogen atoms of a molecule, is considered to be a fundamental and useful network descriptor. We study the problem of constructing geometric networks on point sets in Euclidean space that minimize the Wiener index: given a set $P$ of $n$ points in $\mathbb{R}^d$, the goal is to construct a network, spanning $P$ and satisfying certain constraints, that minimizes the Wiener index among the allowable class of spanning networks. In this work, we focus mainly on spanning networks that are trees and we focus on problems in the plane ($d=2$). We show that any spanning tree that minimizes the Wiener index has non-crossing edges in the plane. Then, we use this fact to devise an $O(n^4)$-time algorithm that constructs a spanning tree of minimum Wiener index for points in convex position. We also prove that the problem of computing a spanning tree on $P$ whose Wiener index is at most $W$, while having total (Euclidean) weight at most $B$, is NP-hard. Computing a tree that minimizes the Wiener index has been studied in the area of communication networks, where it is known as the optimum communication spanning tree problem.


Introduction: Obesity is characterized by excessive deposition of fat in adipose tissue and is associated with the development of pathological damage in several metabolic processes that are associated with oxidative stress and inflammation. Objective: To evaluate the levels of adiponectin, inflammatory markers and oxidative markers, with the objective of determining a biomarkers profile in adults that influences the metabolic risk of developing the metabolic syndrome (MetS). Methods: The groups studied included 84 adults (48 Without MetS and 36 With MetS). General and biochemical parameters were determined. Adiponectin levels, inflammatory markers [C-reactive protein (CRP)], interleukin 6 (IL-6), adenosine deaminase (ADA), dipeptidyl peptidase-IV (DPP-IV) and oxidative markers [thiobarbituric acid reactive substances (TBARS), sulfhydryl groups (SH), total ferric antioxidant power (FRAP) and vitamin C] were also measured. Results: The MetS group presented a significant increase in insulin, triglycerides, cholesterol, low-density lipoprotein cholesterol (LDL-C), glutamic-pyruvic transaminase (GPT) and uric acid, as well as gamma-glutamyl transferase (GGT), glutamic-oxaloacetic transaminase (GOT), and vitamin C. Conclusion: The combination of IL-6, ultra-sensitive C-reactive protein (us-CRP), ADA, DPP-IV and the increase of TBARS, with the reduction of vitamin C, SH groups and adiponectin, promote inflammation and compromise insulin sensitivity, thus presenting an active role in the pathogenesis of MetS. These findings are significant because they may assist in monitoring clinical changes, in the prevention of future cardiometabolic events in individuals with MetS, and in the identification of inflammatory and oxidative markers that assist in the monitoring and prevention of MetS.


Conventional oxide‐based thin‐film phototransistors (Ph‐TRs) with a hybrid structure with additional photoabsorbers show limitations in real‐time on/off operations without additional input bias. Here, hybrid InGaZnO (IGZO) Ph‐TRs utilizing zeolitic‐imidazolate‐framework‐67 (ZIF‐67), an electrically insulating material with a unique metal‐to‐metal charge transfer (MMCT) pathway enabling charge migration, are presented. A wide photodetection range and fast response/recovery speed without additional gate bias are achieved. In particular, ZIF‐67 used as a photoabsorber exhibits absorption of visible light over a wide range of wavelengths. Photoexcited electrons migrate through the MMCT pathway between Co ions and migrate to the IGZO conduction band, causing a significant change in the photocurrent (Iph) of the hybrid ZIF‐67/IGZO Ph‐TR. In the dark, ZIF‐67 immediately returns to the insulating state, resulting in a fast rise/fall time under dynamic photo‐stimulus. In addition, it exhibits repeatable photo‐sensing performance without persistent photocurrent behavior under pulsed light‐on/off cycles. A high photosensitivity of 108 for red light (592 nm, 0.1 mW cm–2) is obtained as it suppresses the dark current and amplifies photocurrent generation in the subthreshold gate voltage region. This combination of fast response time, high photosensitivity, and high stability is promising for ideal Ph‐TRs, enabling real‐time detection even for high‐frequency operations.


This report examines the use of grandmother figures in the construction of imagined communities in Arab American literature. Through the lens of diaspora studies, it argues that grandmother figures become integral in the creation of an Arab American imagined community based on two main tropes: a theoretical collapse between notions of patriotism and the maternal figure (in which the homeland becomes the Motherland) and the tendency of second-generation Arab American authors to connect their immigrant grandmothers to ethnic homelands. In exploring this connection, the report argues that the creation of an Arab American imagined community is necessitated by anti-Arab racism in the United States and the need for the community's authors to be seen in tandem with the literary traditions of other ethnic minorities in America. The report problematizes the


The power grid, which is one of the important infrastructures, has a very challenging issue to stably manage electric power. The Electrical Network Frequency (ENF) which is the supply frequency on the power grid, however, has small variations near a constant frequency over time. In this paper, we studied the feasibility of predicting ENF values to operate the power grid reliably. To forecast ENF values, we analyzed the ENF signals by using auto-correlation and correlation coefficient. Based on the analysis results, we employed two approaches to forecast ENF values using a kernel regression model with correlation coefficient and autoregressive moving average model. To evaluate the accuracy of the proposed prediction algorithm, we experimented ENF data for 29 days in three power grids of the United States; the Eastern, the Western, and the Texas power grid. The results of our suggested methods presented the remarkable performance in forecasting ENF signals.


Lewis–Skyrms signalling games have been studied under a variety of low-rationality learning dynamics. Reinforcement dynamics are stable but slow and prone to evolving suboptimal signalling conventions. A low-inertia trial-and-error dynamical like win-stay/lose-randomise is fast and reliable at finding perfect signalling conventions but unstable in the context of noise or agent error. Here we consider a low-rationality hybrid of reinforcement and win-stay/lose-randomise learning that exhibits the virtues of both. This hybrid dynamics is reliable, stable and exceptionally fast.


In recent years,customer satisfaction (CS) has attracted many researchers' interests,its study has come down to the field of the mechanism, evolutionary trend, influence on the marketing strategy and loyalty of the customer to enterprise,etc..But few people study the CS in industrious markets and related problems from the viewpoint of the enterprise consumption.The paper,from the viewpoint of the relationship of sale and consumption between enterprises,brings forward the concept of Enterprise Satisfaction(ES) in the supply-chain and studies the behavior characteristics of ES and its influence on the transfer of expectations in the supply-chain.The conclusion is that the managerial level and the state of ES are closely related to the transfer of CE in the supply-chain.


In the Netherlands, there is a need to determine the capacity of bridge decks as a large number of them were built back in the 60's and 70's. Since then, not only a lot of additional safety requirements have been incorporated into the modern codes but the traffic flow has also increased drastically. The current research deals with this question by taking into account arching action or compressive membrane action (CMA) in transversely prestressed decks on concrete girders. CMA is a phenomenon that occurs in deck slabs with edges restrained against lateral movement by stiff boundary elements. This restraint induces in-plane forces in the slab affecting both the flexural and the punching shear capacities. Existing methods were modified and a MATLAB program was developed to include the effect of CMA and the transverse prestressing to calculate the punching shear capacity of bridge decks. It was concluded that transverse prestressing enhances the CMA and improves the structural behaviour. However, detailed experiments are being carried out to further investigate the effect of different parameters, like geometry of the deck and the Transverse Prestress Level on the punching shear strength.


ABSTRACT Multiple sauropod-track-bearing horizons occur in the Middle Jurassic Shaqiaomu Formation, in the Chaya Group of Eastern Tibet. These add to the report of a previously described sauropod trackway, which is a famous tourist attraction and became part of a folkloric legend. From an ichnological point of view, multiple track-bearing levels are consistent with the previous report of sauropod tracks, but allow for recognition of nine other levels with a cumulative total of ~88 tracks from which eight recognisable trackways have been identified. These range in size (pes length) from 22.0 to 99.3 cm, with the larger ones all associated with the appropriately named Dajiaoyin (meaning 'large footprints') site. The presence of sauropod tracks in the finer grained argillaceous, lower energy deposits, is characteristic for terrestrial facies environments favoured by sauropods. The track-bearing layers belong to continental shelf sequences that form part of the Lower-Middle Jurassic forearc basin deposits in the southern Qiangtang subterrane.


Experiments found that learning during wakefulness led to a net enhancement of synaptic strength, accompanied by the neural dynamical transition from tonic to bursting firing, while the net synaptic strength decreases to a baseline level during sleep, accompanied by the transition from bursting to tonic firing. In this paper, we provided a model of synaptic plasticity, which can realize synaptic strength changes and neural dynamical transitions for wakefulness-sleep cycle by using a coupled Hindmarsh-Rose neurons. Through numerical simulation and theoretical analysis, it was further found that, the average synaptic weight of the neural network can arrive to a stable value during either prolonged wakefulness or prolonged sleep, which depends on the ratio of some specific parameters in the model. Particularly, the synaptic weights exhibit a stable log-normal distribution observed in real neural systems, when the average synaptic weight arrives to the stable value. Moreover, the fluctuation of this weight distribution is positively correlated with the fluctuation of noise in the synaptic plasticity model. The provided model of the synaptic plasticity and the results of its dynamics can provide a theoretical reference for the physiological mechanism of synaptic plasticity and neuronal firings during the wakefulness-sleep cycle, and are expected to have potential applications in the development of therapeutic interventions for sleep disorders.


Recent legislation mandated a statewide accountability program for California's Community Colleges. This study describes the experiences of four colleges that received pilot program grants. The main finding was that accountability had two meanings. At the state level it ties to educational finance, and the desire to make policy based on objective, defcnsible information. At the local, college level it links to institutional effectiveness. Many of California's colleges currently lack the technical resources for an accountability or institutional effectiveness program. A plan to improve readiness for accountability included basic data collection and reporting, in-depth accountability studies, surveys of student satisfaction and long range program effectiveness, improved data collection, and a clearitighouse.


The tea industry is a highly labour intensive industry. Besides the tea industry, a large number of workers are employed by the subsidiary and ancillary industries. Workers are employed on a family based, and the most significant feature of the tea industry is that almost fifty percent of its workers are women. However, it is a pity that although women workers play a very important role in the tea industry, very little is known about them in the world outside. They are portrayed as a deprived lot, unabashedly exploited by their employers, society and family members. Before the Equal Remunerations Act 1976, women were paid lower wages than men. In 1990 after the Act was implemented in its full content they are being paid equal wages as men. Unfortunately, discrimination against women is still visible. Women workers do not receive subsidised ration or medical benefits for their dependants. In some gardens, even pregnant women do heavy jobs, leading to medical complications during childbirth. A female worker is still treated as inferior While male members relax, drink and enjoy themselves after working hours, the female members are left to do the house-hold chores all by themselves. They are significant contributors to the industry as well as to their household. Situating this dynamics of women losing out in employment on the one hand and their increasing role in the industry and household on the other, this paper provides an account of their negotiations at multiple spheres of work and life. The paper through case studies establishes across various contexts that women have negotiated and emerged from the contours of power and authority and their own spaces at work and the household.

Low‐intensity extracorporeal shock wave therapy (Li‐ESWT) has been applied in urolithiasis and some chronic diseases. We performed a systematic review and meta‐analysis to assess the efficacy of Li‐ESWT for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).


At the spots of enterprises experiencing rapid environmental changes, necessity for ceaseless managemental innovation is raised. We can't deny that management quality is also a part of such managemental innovation. Introduction of management quality by an organization is different from introduction of other individual innovative techniques. Management quality is not one time project but complete historical change program to be pursued continuously. Furthermore, it must be understood as a strategic 'Quality Journey' looking for far future of an organization. Malcolm Baldrige Model has been increasingly used in Korea as a global standard for management quality. The model, however, has shown a number of limitations in application due to nonsystematic elements in the implementation process. The deployment process of the model should be detailed through a real world case study. In this research, we proposed a quality evaluation standard model which is suitable for the Korean public enterprise based on the Malcolm Baldrige Non-profit Criteria, and examined the model. A 7-Point Likert Scale was used based on the seven categories within the 2007 Malcolm Baldrige Non-profit Criteria: Leadership, Strategic Planning, Customer and Market Focus, Management Analysis and Knowledge Management, Workforce Focus, Process Management, and Results. Furthermore, we analysed the validity and causal relationship among the factors within the model. Through the above case study, following common factors for successful Malcolm Baldrige Model have been derived. The following is a summary of the results of this study. First, for Malcolm Baldrige Model management, needs powerful support Leadership. Second, for Malcolm Baldrige Model management, needs systematic Strategic Planning. Third, for Malcolm Baldrige Model management, needs the continuous Customer and Market Focus. Fourth, for Malcolm Baldrige Model management, needs systematic Measurement Analysis and Knowledge Management. Five, for Malcolm Baldrige Model management, needs systematic Workforce Focus. Six, for Malcolm Baldrige Model management, needs systematic Process Management. The finding are surely necessary factors to arrange the human resource management for upgraded management quality, those factors help to explain why all enterprises consider human resource as the strategic view.

The New Literature advertiesements withess the development history of the New Literature thus has values in many aspects.It not only promotes the communication of the New Literature authors and works,but also provides a lot of valuable original documents and edition information.It is the classical model for modern advertisements of books and periodicals.


Tailings management presents a key challenge in eff ectively exploiting oil sands resources, since ever y barrel of bitumen recovered generates two to three barrels of tailings waste. With the recent adoption of Canad ian Energy Resources Conservation Board Directive 74, however, this waste can no longer be discharged as-i s, but must be dewatered and rendered trafficable within f ive years of generation. Not only are process taili ngs targeted for remediation, but also the approximatel y 700 million m 3 of mature fine tailings that have been accumulated over decades of processing and lie in l arge containment ponds. Chemical strategies for dewatering tailings involve treatment with additives that bind the tailings pa rticles together into larger flocs, with floc size and shap e influencing settling rates and compaction. Mecha nical operations such as centrifugation or even pipeline transport, however, can break apart flocs, altering their sedimentation and packing behavior. In this resear ch, mature fine tailings were treated with a range of organic flocculants and coagulants to induce floc formation . Floc breakage and reformation were assessed rheo logically and by dynamic measurements of particle size distri butions.


A single-layer prephased 1-bit reflective metasurface is proposed to achieve single-beam radiation patterns under normally incident plane waves. By integrating the true-time delay lines with the prephase technique, the proposed design resolves the inherent symmetric beam issue of the conventional 1-bit reflective metasurface design in a single-layer design. To verify the proposed design, three 1-bit reflective metasurfaces comprising 20 × 20 unit cells with single beams pointing separately at <inline-formula><tex-math notation="LaTeX">$-15^{\circ }$</tex-math></inline-formula>, <inline-formula><tex-math notation="LaTeX">$15^{\circ }$</tex-math></inline-formula>, and <inline-formula><tex-math notation="LaTeX">$30^{\circ }$</tex-math></inline-formula> are designed and measured over frequencies of 35.0–43.0 GHz. Simulated and measured results show that the proposed prephased 1-bit reflective metasurface can achieve single-beam patterns under normally incident plane waves using only one layer.


The situation in friction-twisting when the yarn is not slipping completely is examined in general terms. The well-known situation in engineering drives is reviewed as an introduction. It is then shown that, within a range of combinations of relative changes in forward velocity and twist, the yarn will be fully gripped on the incoming portion of the friction surface and so will be positively twisted and forwarded. The yarn is slipping over a zone on the departure side. The general equations for a simple case are stated, and a graphical means of showing the conditions for different modes of operation is illustrated.

The sphere decoder (SD) has been utilized for maximum likelihood (ML) detection in MIMO systems. In order to improve system performance, the SD is usually combined with the error correction codes where soft decoding is utilized. The list sphere decoder (LSD) was introduced to generate a candidate list, which can provide soft information to the outer decoder. Unlike the conventional sphere decoder, the LSD has the candidate list updating and new radius generation units, which causes extra complexity and latency. In this paper, we present a novel radius updating architecture, which can obtain a new radius much faster than the conventional method. Furthermore, we propose an efficient candidate list updating scheme, which can significantly save the complexity (without affecting the decoding speed) of updating the candidate list used to compute soft information.


In a seminal paper, Karp, Vazirani, and Vazirani show that a simple ranking algorithm achieves a competitive ratio of 1-1/e for the online bipartite matching problem in the standard adversarial model, where the ratio of 1-1/e is also shown to be optimal. Their result also implies that in the random arrivals model defined by Goel and Mehta, where the online nodes arrive in a random order, a simple greedy algorithm achieves a competitive ratio of 1-1/e. In this paper, we study the ranking algorithm in the random arrivals model, and show that it has a competitive ratio of at least 0.696, beating the 1-1/e ≈ 0.632 barrier in the adversarial model. Our result also extends to the i.i.d. distribution model of Feldman et al., removing the assumption that the distribution is known.
 Our analysis has two main steps. First, we exploit certain dominance and monotonicity properties of the ranking algorithm to derive a family of factor-revealing linear programs (LPs). In particular, by symmetry of the ranking algorithm in the random arrivals model, we have the monotonicity property on both sides of the bipartite graph, giving good "strength" to the LPs. Second, to obtain a good lower bound on the optimal values of all these LPs and hence on the competitive ratio of the algorithm, we introduce the technique of strongly factor-revealing LPs. In particular, we derive a family of modified LPs with similar strength such that the optimal value of any single one of these new LPs is a lower bound on the competitive ratio of the algorithm. This enables us to leverage the power of computer LP solvers to solve for large instances of the new LPs to establish bounds that would otherwise be difficult to attain by human analysis.


Entecavir(ETV), a cyclopentyl guanosine analogue, acquired the admission of FDA on sale as an new potent anti-HBV drug recently. The clinic trial project of ETV is so far the largest scale, which at the first directly compare two antiviral drugs—ETV and lamivudine(LVD). The trial results demonstrate ETV is an potent drug against HBV,and similar to LVD in safty, and superior to LVD in drug resistance. We describle it from pharmacology, pharmacokinetic, clincial efficacy and viral mutation.


This paper examines three myths of gender and race that operate in engineering education, and uses a review of the literature as well as findings from the authors' research to address them. First, we address the tendency to construct studies to look for difference and to interpret findings in ways that reduce results to genderor race-based traits. Second, we consider the importance of getting beyond considerations of singular identities in isolation and considering the complexities of intersecting identities of race, class, gender, and sexuality. Examining a case study of longitudinal interviews with a queer-identified Latina engineering minor will elucidate the importance of considering intersectionality as part of a holistic analysis. Third, we argue for gender studies in engineering that attends to men and masculinities, not just women's experience.


History、government、market and society controlled the direction of private education since the establishment of the nation.Based on the historical institutionalism to research the path dependence of private education is very useful to understand the influence factors to strengthen and remodel the old institutionalism.The article points out that the change of our private education system is not the "issues-tactics",but under the role of internal and external causes together.If only the private education go out of the old cycle path and open up new development way,it will achieve a real sense of the system innovation.


The Douglas fir beetle, Dendroctonus pseudotsugae Hopkins, normally mass attacks Douglasfir, Pseudotsuga menziesii (Mirb.) Franco, at a density of 8–10 females/0.1 m2. An attack at this density kills the tree and establishes a new beetle brood. When the aggregation pheromone Douglure (2 attractants and 2 host cofactors) and a natural aggregation inhibitor 3-methyl-2-cyclohexen-l-one (MCH) were placed on or near live hosts simultaneously and in varying ratios, the colonization behavior of the Douglas fir beetle was altered. These alterations in behavior affect number of attacks, total height of attack, length of parent galleries, and proportion of successful galleries. Below a threshold of 4–6 attacks/0.1 m2 of bark surface, the females were unsuccessful in establishing a brood, and the tree survived. These results suggest a new concept (the pest population sink), which modifies the behavior of this pest with chemicals.


This article examines neglected orchestral works by six Canadian composers: Rodolphe Mathieu, Colin McPhee, John Weinzweig, Harry Somers, Istvan Anhalt, and R. Murray Schafer. Despite the considerable professional accomplishments and career achievements of these composers, each has at least one orchestral work in his catalogue that failed to make a good impression with the musical public or has never been heard in live performance. The article attempts to find why these compositions did not win a place in the repertoire and also considers how these works illustrate broader issues relating to the Canadian orchestral repertoire.


In 2017, concerns regarding adverse events (AEs) associated with the Mirena levonorgestrel intrauterine device were largely echoed in the media in France. This resulted in a tremendous reporting of AEs to pharmacovigilance centres. The aim of this study was to describe the reporting of AEs regarding Mirena in France and to study the impact of media coverage on this reporting.


In this study, a novel packaging structure for open-channel sensor was successfully demonstrated by using the sacrifice-replacement method. This method was patterned JSR THB-151N photoresist to fabricate an open space to contact medium. The sacrificial-barriers of 75 and 150 mum thickness have been fabricated with good reproducibility by using single and double coating processes. Optimized fabrication parameters were achieved straight and nearly vertical sidewall profiles. In addition, after the encapsulation process, JSR photoresist has been stripped clearly and easily without residues in stripper solutions. Finally, the sensing channel was reserved in packaging body resulting from sacrifice-replacement approach.


Micromorphology of glandular hairs on the leaves of Salvia officinalis L. and Salvia triloba L. was investigated by light microscopy. We noticed similiarity and variation between the two species regarding morphology of glandular trichomes. Two main types of glandular trichomes were identified on both species: peltate and capitate. Peltate trichomes consisted of a basal cell, one stalk cell and a large multisecretory head in S. officinalis L. In S. triloba L. peltate trichomes posses a basal cell, a short unicellular stalk, and a large secretory head with 8 secretory cells. In Salvia officinalis L., four types of capitate trichomes have been distinguished. Five types of capitate trichomes have been found in Salvia triloba L. The fifth type of capitate trichome, called digitiform trichome was found in S. triloba L. This determined interspecific diversity between the two Salvia species.


In 1973, Japan adopted WECPNLJ which is defined as a modified index of ICAO WECPNL, as an index of aircraft noise evaluation, and enacted"Environmental Quality Standard for Aircraft Noise."So the Government has made all countermeasures to alleviate the aircraft noise impact around the airport.As a result, the noise exposure situation has been greatly improved for these twenty-five years.To evaluate noise exposure, an aircraft noise prediction model(JCAB Model)was developed by Civil Aviation Bureau of the Ministry of Transport of Japan(JCAB).The procedure for aircraft noise prediction has not been changed basically, but JCAB has been trying to improve the accuracy of noise prediction.First, this paper briefly reviews the Standard and a noise evaluation index WECPNLJ in the Standard.Then, it describes the basic idea of an airport-noise prediction model JCAB Model, which has been developed by JCAB, together with some recent result of examination about the accuracy of noise prediction.Finally, it refers to the relationship between WECPNLJ and Lden.


We extend the results about the fluctuations of the matrix entries of regular functions of Wigner matrices to the case of sample covariance random matrices.


Abstract Relative efficacy of Attentional Skills Training and Systematic Rational Restructuring as short-term (50 minutes each), cognitive interventions was determined on a sample of ninth-grade girls from India. Only Attentional Skills Training and not Systematic Rational Restructuring has been found to be effective for high test-anxious girls (regardless of intelligence), not only in the reduction of state test anxiety and its worry state component, but also in the reduction of anxiety interference and in the improvement of the estimated percent time spent on task. However, neither of the interventions improved the performance on the two difficult experimental tasks when compared to controls.


In the brief essay on the theme of revisiting or revisioning the works of Rudyard Kipling, I chronicle an account of my encounter with post-modernist literary criticism, which embodies or accumulates beneath its broad penumbra, dozens of social, scientific, philosophic, political, linguistic, and narrative aesthetic perspectives. My paper aims at coursing a bit through the history of the Raj, in a search to contextualize comprehensively the material and psychological foundations of this specific series of representations of India between 1890 and 1935, following the Sepoy Rebellion (1857) and the end of the official Raj. Then, I apply some of the principles of Barthes, Derrida, Spivak, and Foucault to Kipling's representative oeuvre, in an effort to verify whether the "new criticism" and "new historicism" have the capability to enhance readers' appreciation and comprehension of colonialist literature's animus in general and the specific significance of Kipling in the pantheon of British Empire apologists and sympathetic participants.


Brain tumor segmentation is a very important task in medical image processing. Early diagnosis of brain tumors plays a crucial role in improving treatment possibilities and increases the survival rate of the patients. For the study of tumor detection and segmentation, MRI Images are very useful in recent years. One of the foremost crucial tasks in any brain tumor detection system is that the detachment of abnormal tissues from normal brain tissues. Because of MRI Images, we will detect the brain tumor. Detection of unusual growth of tissues and blocks of blood within the system is seen in an MRI Imaging. Brain tumor detection using MRI images may be a challenging task due to the brain's complex structure. In this paper, we propose an image segmentation method to detect tumors from MRI images using an interface of GUI in MATLAB. The method of distinguishing brain tumors through MRI images is often sorted into four sections of image processing as pre-processing, feature extraction, image segmentation, and image classification. During this paper, we've used various algorithms for the partial fulfillment of the necessities to hit the simplest results that may help us to detect brain tumors within the early stage.


A model to assess the failure rate of equipment under use conditions is proposed. This model links noncontrolled variables to a piecewise failure rate combined with a proportional hazard model. Two influential variables are considered. One is the temperature characterizing the outdoor climate, and the other one is moisture—as an intrinsic variable. The maximum likelihood estimates of the model parameters are obtained. The efficiency of the method is evaluated through simulated data. Results on data from the field are provided.

To confirm a causative allergen in atopic dogs could test through intradermal skin testing (IDT) or allergen-specific IgE serology testing (ASIS). ASIS is more practical, convenient and safer. However, the results of ASIS could be affected by source and type of allergen. Crude allergen extracts were still used in commercial testing and protein antigens of skin microbes were not included in the panel of testing. In this study, our group developed serology test for confirming house dust mite allergy called Dermatophagoides farinae and D. pteronyssinus, and measuring specific immunoglobulin to skin microbes on dogs like Malssezia pachydermatis yeast and Staphylococcus pseudintermedius �bacteria. The results was found that high IgE levels to house dust mites could be used to differentiate atopic dog with allergy to house dust mites and atopic dogs without allergy to house dust mites. Moreover, IgG1 levels could also use to differentiate house dust mite allergy and non-house dust mite allergy by using lower sample volumes than IgE about 100 times. In the other hand, total IgG and IgG2 levels could not be used to differentiate house dust mite allergy and non-house dust mite allergy in atopic dogs. Both of IgE and IgG1 levels showed the same degrees of agreement to IDT. By investigation through two-dimensional IgE blotting, ten proteins of house dust mites that related to house dust mite allergy in atopic dogs were found, Der f 28 protein is interesting and should be selected to apply for a component-resolved diagnostics.� Alpha-enolase, serine protease, and arginine kinase are the critical protein to be a cause of cross reaction. The results of specific immune response to skin microbes were found that atopic dogs had higher specific IgE levels to both skin microbes than healthy dogs. This indicated that skin microbes could act as allergen in atopic dogs. Other specific IgG1 and IgG2 to these skin microbes also high.� However, none of any types specific immunoglobulin to skin microbes related to skin severity scores in atopic dogs determining through the Canine Atopic Dermatitis Lesion Index. We concluded that levels of specific immunoglobulin to skin microbes did not relate to skin severity. �


In system-on-chip design, automating design reuse is one of the most important issues. Since most Intellectual Properties(IP) are provided by different vendors, they have different interface schemes, and different data rates. In order to automate design reuse, methods for combining system components with incompatbile I/O and interface protocols, must be developed. Furthermore design interfaces between interacting components is an error-prone task. In this report, we propose the interface architecture in which queues are used for data transfers between components with incompatible protocols. We also describe a method to generate system interface from the protocol specification.

This paper describes a laboratory exercise that provides students enrolled in introductory nanotechnology courses with an opportunity to synthesize polymer structures with micro- and nanoscale dimensions. Polyvinylpyrrolidone (PVP) films deposited on corrugated PDMS stamps using student-built spin coaters were transferred to clean, dry substrates via microcontact printing. The microscale dimensions of the resulting patterns were characterized in class using optical microscopy. Characterization with atomic force microscopy (AFM) was used for visualization of nanoscale vertical dimensions of the structures. This laboratory investigation highlights the following concepts often associated with polymer nanostructure fabrication: polymer synthesis, surface chemistry, soft lithography, and contact angle. It is noteworthy to mention that this laboratory exercise demonstrates the feasibility of utilizing nontoxic, cost-effective, bench-top materials to teach and investigate fundamentals associated with fabrication...


Agar has been widely used as a gelling agent of the media for plant tissue culture. However, agar maycontain growth inhibitory substances.1} To removethe inhibitory effects of agar, highly purified agar is used or charcoal is added to the agar medium. On the other hand, there are many polysaccharides which are used for processed foods as gelling agents, e.g., carrageenans from seaweeds and pectins from higher plants. Recently gellan gum(Gelrite, formerly known as PS-60) produced by Pseudomonas elodea was developed as a gelling agent2) and used for bacteriological media.3) This report describes the effects of several gelling agents on in vitro culture of various plant tissues.


The following article analyzes the Betancourt Doctrine as one of the instruments, yet not the only one, of the foreign policy of defense and promotion of democracy enacted by the Betancourt constitutional government (1959-64). Resorting to primary sources of American and Venezuelan archives, and applying the method of historical analysis, it will be seen how the Betancourt Doctrine, initially conceived as a multilateral regional tool, ended being reduced to a unilateral policy of the Venezuelan government. Furthermore, we will highlight the role of public support and especially of covert help as concomitant strategies to contain both right wing military dictatorships as well as Fidel Castro's communist regime.


Introduction—In some of its aspects hydrology is as old as its foster parents—geography and meteorology. Among the earliest engineering operations of record is the construction of wells, frequently described in the Book of Genesis—an example of applied hydrology. (Some wells of extremely ancient and probably pre-historic construction are still existent and in service in Arabia. They are fully described in Thomas Ewbank's "Hydraulics and Mechanics," New York, 1870.) As in the case of geography and meteorology, so also hydrology has been mainly qualitative in character until recently. Only with the beginning of its quantitative development could it be considered that hydrology definitely emerged from the other Earth-sciences.

The final portion of the session is devoted to discussion, debate, and Q&A.


The invention discloses a shooting method, a shooting apparatus and an electronic device. The method comprises the following steps: receiving a preset type of non-visible light emitted or reflected by a shot object to obtain distribution information of the preset type of non-visible light of the shot object, preprocessing the distribution information of the preset type of non-visible light to obtain image information of a target type image, and finally, generating a target type image corresponding to the shot object based on the image information. Therefore, the invention provides a shooting method based on non-visible light imaging. The method is used for receiving and correspondingly processing the preset type of non-visible light emitted or reflected by the shot object to image the shot object, so when the method disclosed by the invention is used for shooting and imaging, the method is not limited by the illumination conditions of the visible light and can be used for normally imaging under no light or shimmer and other conditions.


In view of a time lag between the time that the prey perceive predator signals and make some changes or behavior responses, we establish a predator–prey system with direct and indirect predation in this paper. First, we investigate the existence, boundedness, and global asymptotical stability of the positive equilibrium status. Next, by perturbing the mortality rates of prey species and predator species, we stretch the deterministic system to the stochastic scenario and investigate the existence of stochastic process and the global asymptotical stability of the equilibrium status. The analytical findings show that fear affects the value of the equilibrium status, and stochastic disturbance affects its stability, but time delay has no effect if some conditions are satisfied, which are verified by some examples and numerical simulations.


Writing center directors (WCDs) often situate their programs in physical and virtual spaces without fully studying the pedagogical and political implications of their decisions. Without intense study, writing centers risk building programs within spaces that undermine their missions and philosophies. In The Production of Space, Henri Lefebvre argues that "From the analytic standpoint, the spatial practice of a society is revealed through the deciphering of its space" (38). The study of space also reveals important political and financial priorities within the institution. Furthermore, the positioning of buildings and the spatial layout of a campus display the institution's priorities and attitudes toward writing center work. Theorizing the Online Writing Lab (OWL) through the lens of cultural and political geographies, it becomes apparent that the physical spaces of many writing centers are not as sustainable as WCDs might like, and in many ways, they are marginalized within the larger institution. This dissertation prompts a rearticulation of place and space in the writing center. In this dissertation, I argue that in an attempt to rethink current practices, the virtual space of the writing center should perpetuate, extend, and improve the social practices employed in our physical spaces. I draw from mapping exercises to inform my critique in an attempt to advance our understanding of writing center physical and virtual spaces. The changing geographical and cultural landscape of the institution demands that writing centers pay close attention to spatial implications as they employ technology to create dynamic virtual resources and more sustainable spaces.


The findings of a study of 877 children placed in residential care in Hong Kong highlight the paramount importance of parental involvement in the child's prospect of returning home, and challenge decisions in discharge planning that do not take into account an overall view of the needs of the child concerned. In Hong Kong, few children are placed in residential care--institutional or noninstitutional--for family-related reasons. Their number approximates only 0.11% of the population age 18 or below. This relatively judicious use of the service, as compared to its use in the West, may be due to the cultural emphases of the Chinese on family solidarity and self-reliance, which have been upheld in present-day Hong Kong Lau 1982; Chow 1987; Lee 1991 , and which contribute to a general reluctance of people to be dependent on "welfare." Most parents strive to bring up their children themselves, and will resort to residential child care only when the family and its support network have proved incapable of providing care and no alternative is in sight. Once a child is admitted into care, however, she or he may expect a rather long stay and perhaps several placement changes Tam & Ho 1993 . This apparent contradiction is worth looking into to identify the factors influencing the prospect of these children being reunited with their parents. A considerable amount of research pertaining to placement outcomes has been conducted in the United States and the United Kingdom over the past three decades. The research findings suggest that the likelihood of a child's return to his or her own home is related to four different sets of variables: intake characteristics, duration in care, service strategies, and the extent of parental contact with the agency and the child while the child is in care. Studies of intake characteristics and placement outcomes indicate that those children who are likely to return home tend to be those who were admitted because of a family crisis such as the death, illness, or hospitalization of a parent; and those who came from large families where there were affectionate relationships with siblings and where parent-child relationships were maintained Fanshel & Maas 1962; Parker 1966; Jenkins 1967; Vernon & Fruin 1986 . By contrast, lengthy stays in care were associated with the following factors: familial conditions such as marital conflict, psychosocial problems of parents (including incompetence, alcoholism, and drug addiction), or desertion or separation of the mother from the husband or child prior to placement; children who were functioning at a below-average intellectual level, had permanent physical disabilities or serious emotional or personality problems, or who were suffering from tenuous or warped parent-child relationships perhaps owing to physical abuse and neglect; and adverse factors such as inadequate housing and the economic circumstances of the family Fanshel & Maas 1962; Parker 1966; Jenkins 1967; Murphy 1968; Maas 1969; Rowe & Lambert 1973; Sherman et al. 1973; Vernon & Fruin 1986 . In addition, demographic variables such as religion, ethnicity, age at placement, and mother's age at the time of placement were related to duration of care Parker 1966; Jenkins 1967; Murphy 1968 . Parker 1966 found that children placed in a family foster home for the first time were more likely to return to their home. More recent research also found that the rate of leaving care decreased as duration in care lengthened Stein & Gambrill 1971; Stein et al. 1978; Vernon & Fruin 1986 . Service strategies were found to be related to placement outcomes. Sherman et al. 1973 showed that intensive service strategies were more likely to facilitate the child's return home than regular practice. The Alameda Project revealed that if family problems were successfully resolved, the majority of children could be reunited with their parents Stein & Gambrill 1971; Stein et al. …


Novel interpenetrated polymer network type microparticles of gelatin and poly(vinyl alcohol) (PVA) were prepared by reverseemulsion crosslinking method using glutaraldehyde (GA) as crosslinking agent. Microparticles morphology, particle size, swelling behaviour and drug loading/release are discussed in respect to the preparation parameters such as the influence of the polymer concentration in the aqueous phase, pH of the aqueous phase, ratio between the total amount of polymers and the amount of crosslinking agent and the ratio between Gel and PVA in initial aqueous solution (w/w). Chloramphenicol (CLF), a model hydrosoluble drug, was successfully loaded into these microspheres.

Harold Jaffe's latest volume, Strange Fruit & Other Plays , is a compelling ex-ploration of Art and History. The work comprises a selection of dramatic texts, a new literary form for Jaffe, author of more than thirty books. The title of the book derives from Billie Holiday's anthemic song, "Strange Fruit," about the horror of a lynching in the South. The song was written by a Jewish high school teacher from the Bronx, who was also a writer and activist. He handed it to Billie Holiday after a gig in a Greenwich Village club. The song immediately moved her.

Clash of civilizations over an elevator in Piazza Vittorio by Amara Lakhous - winner of the prestigious Flaiano and Racalmare Leonardo Sciascia awards - has been the object of great attention by scholars of Italian Literature, Comparative Literatures and Migration Studies who have based their analyses, except for a few works, on the Italian self-translation of the novel (2006) and subsequent translations from the Italian text. However, most of these studies overlook the fact that the novel was originally written in Arabic and published in Algeria in 2003. This article examines both the Arabic and the Italian versions of Clash of civilizations over an elevator in Piazza Vittorio with reference to the different horizons of expectation of the readers of the two texts. This approach allows to understand a distinctive feature of Lakhous' work that has been neglected by previous studies: the way the novel interacts with two different social imaginaries and operates to transform them.


Abstract The advancement of technology along with the unprecedented situation like Covid-19 has brought a big revolution in the e-commerce industry. The consumer finds ease in shopping domestic appliances online as compared to traditional shopping. The present study is being conducted to investigate the factors that influence customers' online purchasing intentions (COPI) whereby trust (TT), perceived use and usefulness (PEUU), e-service quality (ESQL), perceived behavior control (PBC), subjective norms (SNM) and consumer online shopping behavior (COSB) were analyzed. A questionnaire was utilised as a survey tool to collect data from 383 respondents using a quantitative methodology. The data were examined using structural equation modelling (SEM) to test the hypothesis, fit the model, and determine the relationship between the variables evaluated. The analysis concluded that consumer online purchase intention (COPI) acts as a mediator between the independent variables (TT, PEUU, ESQL, PBC, SNM) and the dependent variable consumer online shopping behavior (COSB). According to the findings, perceived use and usefulness (PEUU) had a negative influence on purchase intention and behaviour, but consumer online purchase intention had a substantial effect on consumer online purchasing behaviour. The study provides scope and new avenues for future research. In addition to this, it also provides the platform for other researchers to target a specific age, gender, education, or marital status to design a new pattern of online shopping.

The hover performance data of full-scale and model-scale coaxial rotors have been compared with CAMRAD II predictions having a free vortex wake analysis. Performance correlations of a coaxial rotor were made with a variation of key parameters including the rotor spacing and height. To understand aerodynamic behavior of the U.S. Army Aeroflightdynamics Directorate(AFDD)coaxialrotoroperatingoverarangeofReynoldsnumbersfrom36,000to180,000,theReynoldsnumber scaling effect was explored using an airfoil design code, MSES. It was found that the coaxial rotor spacing effect on hover performance was minimal for the rotor spacing larger than 20% of the rotor diameter. The measured performance data showed that more thrust was lost from the lower rotor of a coaxial than the upper rotor due to a larger rotor-to-rotor wake interference effect, and the lower rotor kept only an 81% of the single rotor OGE (out-of-ground effect) thrust whereas the upper rotor maintained a 90%. The lower rotor IGE (in-ground effect) thrust increased quickly by 26% as the rotor approached to the ground from the position of an 80% of the rotor diameter to 10%, and the corresponding IGE power increased by 17%. These thrust and power characteristics were well predicted. Overall, the performance prediction for the coaxial rotor was satisfactory when compared with the measured data.


Concept mastery is one of the main goals in the learning process. This study aimed to analyze the improvement of students' physics concept mastery by implementing challenge-based learning with Edmodo-assisted learning. This study used mixed methods with an embedded experimental model research design. The research sample was 10th-grade students in a public vocational school's food crops and horticulture agribusiness program. Data analysis employed the Rasch model with the help of ministeps software version 4.1.1. The results of this study indicate a significant increase in students' conceptual mastery of +3.44 logit. The average logit value of students' abilities is higher than the average logit value of the item difficulty level. Students' physics concept mastery can be improved through the challenge-based learning model assisted by Edmodo.


Lateral nozzle forces are known to cause severe structural damage to any new rocket engine in development during testing. Although three-dimensional, transient, turbulent, chemically reacting computational fluid dynamics methodology has been demonstrated to capture major side load physics with rigid nozzles, hot-fire tests often show nozzle structure deformation during major side load events, leading to structural damages if structural strengthening measures were not taken. The modeling picture is incomplete without the capability to address the two-way responses between the structure and fluid. The objective of this study is to develop a coupled aeroelastic modeling capability by implementing the necessary structural dynamics component into an anchored computational fluid dynamics methodology. The computational fluid dynamics component is based on an unstructured-grid pressure-based computational fluid dynamics formulation, whereas the computational structural dynamics component is developed under the fr...
