The present work investigates a predictive controller's performance to maintain normoglycemia in type I diabetic patient using a insulin infusion pump. The dynamics of the glucoregulatory system in a metabolic normalized type I diabetic patient was simulated by a nonlinear 19th order model, commonly found in the literature. In the metabolic unnormalized type I diabetic patient this dynamic was simulated regarding the parameters in the previous model not equal to their nominal values. When acting to maintain normoglycemia in a normalized type I diabetic patient, the controller's performance was assessed by the minimum and maximum peripheral blood glucose concentration and the elapsed time for the glucose concentration values return to the interval of 2% around the reference concentration. In an unnormalized diabetic patient the performance was assessed by the elapsed time for the glucose concentration return to the interval of 2% around the reference concentration. The controllers synthesized in this work showed a performance similar to those available in the literature, being, however, more easily implemented and less computationally demanding.


As a teacher educator at the University of Wisconsin, Donald Hones makes "dialogic teacher research" a course requirement to help his students better understand the personal histories and international influences that bring refugees and immigrants to the United States. Hones defines this research as "ethnographic, participatory, and narrative," with the purpose of illuminating economical, political, social, and cultural relationships and "extend[ing] these dialogues to promote broader understanding and social justice in schools and communities" (p. xiii). Teacher educators frequently assign their students to fieldwork in schools with diverse populations to expose them to changing U.S. demographics and the need for multicultural education. Hones goes a step further by requiring his students to engage personally with one immigrant or refugee family. In his recent book, American Dreams, Global Visions, Hones argued that teachers must take on cultural roles that inform U.S.-born citizens and empower immigrants. He provided evidence of the lessons learned by four of his students by including their dialogic research projects with Hmong, Mexican, Assyrian/Kurdish, and Kosovar newcomers.


This research was carried out by using 8 oat landraces and 9 registered oat cultivars sown in randomized complete block design with four replications between 2006-2008 years in Kahramanmaras conditions. In the study, it was aimed to evaluate the genotypes in terms of some morphological and agricultural characteristics, as well as to determine the genetic progress achieved in registered varieties in terms of some agricultural traits according to the years they were registered. In the research, grain filling period, sowing-maturity duration, number of panicle in m2, plant height, panicle height, grain number per panicle, grain weight per panicle, grain filling ratio, grain filling index and protein ratio in grain were investigated. According to the mean of two years, except for number of panicle in m2, grain weight per panicle, grain number per panicle, 1000 grain weight and protein ratio in grain genotypes were significantly different for all investigated traits.


Secret Share (SS) is becoming a very hot topic within the scientific community. It allows us to split a secret into fragments and to share them among parties in such a way that a subset can recompose the original information. SS techniques assure a high redundancy degree, but the security level is fixed. Therefore, if a minimum number of peers collude then attackers can recompose the secret easily. A possible approach to improve the security of SS is designing nest fragment sharing techniques. In this paper, we propose the Nested Secret Share (NSS) as a more reliable and scalable strategy. In particular, we discuss the security of NSS considering the number of recomposition attempts that an attacker has to perform to retrieve the secret and then we deeply analyse the impact of the redundancy and the number of peers on the secret management against the percentage of compromised nodes. Experiments were promising and showed that the redundancy degree of SS can be highly improved by NSS.


Text classification is a challenging task aimed at identifying categories of text. In order to improve the feature extraction capability of existing shallow text classification models and extract text information hierarchically from bottom to top, a multi-granularity attention model-based capsule network (LMAC) is proposed. This paper adopts a stacked dilated convolutional structure as an encoding module from the perspective of local correlation and long-term dependency. Capturing multi-granular semantic features of text. Combined with capsule network to build a classification model. A multi-granularity attention model based on dilated convolution is proposed, which fully mines multi-granularity semantic features of text by weighting and summing semantic features of different granularities. The effectiveness of the method is validated on 7 datasets for text classification tasks. Compared with the existing research work, the performance is improved significantly. It shows that the LMAC model can mine text semantic features more comprehensively and deeply, and improve the performance of text classification.


Fourteen phase-sensitive radars (ApRES) were deployed on the Filchner-Ronne Ice Shelf (FRIS) to measure variability in its basal melt rate. Melt rates from sites along the Ronne Depression vary seasonally, consistent with the dynamics of the propagation of seasonal dense water from the western ice front into the cavity. Several sites at the back of the FRIS cavity feature a signal with two seasonal maxima. Sub-ice shelf oceanographic data available from one of the sites indicate that this signal is caused by two different pathways followed by the same source water. Inter-annual variability is strongest along a direct flow pathway between western Ronne Ice Front and western Berkner Island. Highest melting occurred in 1999 and 2018, following anomalously low summer sea-ice concentrations in front of the ice shelf. Inter-annual melt rate variability at the back of the FRIS cavity


Objective. Identification of factors of non-productive origin that affect the electromagnetic situation in industrial buildings and the implementation of a sequence of measures to normalize it. Methods. Experimental study of the source of extraneous electromagnetic fields in buildings and structures that can adversely affect workers and sensitive devices in production. To do this, the means of finding such fields were identified and used. The state and description of electric power networks as well as the distribution of the intensity of high-frequency electromagnetic fields are generalized. Electromagnetic safety measures in the production of various purposes are analyzed and presented. Results. Industrial five-storey buildings were inspected for currents in metal structures. The results show that they have significant levels of electric currents in metal structures depending on the riser of the building. It is established that the precondition for the application of safety measures is the analysis of the state of electric power networks, the distribution of the intensity of high-frequency electromagnetic fields, etc. The levels of electromagnetic fields in partially shielded rooms have been experimentally established. Typical dependences of radiation intensity of mobile phones on the signal level from base stations are obtained. The conditions of normalization of the electromagnetic situation in individual rooms and the building as a whole are substantiated. Electromagnetic safety measures have been introduced. Scientific novelty. To minimize the impact of electrical networks on the electromagnetic environment in the building, it is advisable to upgrade it according to the scheme TN-S, or TN-C-S, which reduces the levels of uncompensated electric currents in the network and the corresponding magnetic fields. Practical significance. It is established that: a) it is obligatory to determine the presence of leakage electric currents on grounded bearing structures and engineering networks that generate magnetic fields of hygienically significant voltages; b) reducing the levels of these jets due to technical solutions further reduces the intensity of electro-like processes in metal structures; c) to reduce the levels of high-frequency electromagnetic fields in production facilities, which are formed due to the reflection and re-reflection of electromagnetic waves, it is advisable to use composite shielding materials with controlled absorption and reflection coefficients. This approach will systematize the overall electromagnetic background in the premises and the building as a whole.


A new method combining the scanning nuclear microprobe (SNM) with the pattern recognition of artificial neural network (ANN) was studied for the source identification and apportionment of aerosol particles. A technique of preparing of single aerosol particle sample was developed. A multi-station and multi-parameter data system for SNM was set up. A ANN program package was used for the source identification and apportionment of aerosol particles based on the Micro-PIXE spectra. The new method was preliminarily applied to the PM10 aerosol particles in the atmosphere of Shanghai city.


An important part of any production system is the reproductive performance associated with developing heifers. However, previous research has reported that grazing behavior is learned at weaning, and moving heifers from a drylot environment to a grazing environment immediately following insemination can negatively affect pregnancy success. Therefore, this project was conducted to determine whether this decrease in pregnancy success is associated with diet change alone and how diet change can affect circulating concentrations of progesterone and BUN. Angus crossbred heifers (n = 336) were developed on a forage diet from weaning to breeding. Seven days before the start of the breeding season all heifers were brought into a drylot and synchronized with the Select Synch + CIDR protocol. Immediately after AI, heifers were returned to forage (RNG), returned to forage and supplemented with 2.22 kg/d per animal of dried distillers grains with solubles (RNG-S), or moved into a drylot (DLT). Blood samples were collected on d −7; at AI; and 2, 14, and 42 d after AI. Circulating concentrations of progesterone and BUN were analyzed in all serum samples. There were no differences among treatments in AI or breeding season pregnancy success. Heifers in the RNG-S treatment had greater (P < 0.01) BUN concentrations at 2, 14, and 42 d after AI compared with DLT and RNG. The RNG-S heifers had greater concentrations of progesterone on d 14 after AI (P = 0.02) compared with DLT, and concentrations were greater on d 14 and 42 after AI (P < 0.02) for RNG heifers compared with DLT. In summary, when heifers were developed on a forage-based developing diet and moved to range, range with supplementation, or to a drylot, there was no detectable effect on pregnancy success; thus, a change in diet alone, as long as BCS is not negatively affected, immediately following AI was not sufficient to reduce pregnancy success.


Abstract : This report was developed under SBIR contract for topic AF04-241. TEC developed a measurement and assessment capability to quantitatively determine the structural integrity around cold-worked fastener holes in various locations on aircraft, thereby assessing the aircraft's overall health, targeting necessary maintenance, improving aircraft readiness and air worthiness, and reducing its life-cycle cost. This capability will enable the Air Force to improve its aircraft life cycle management by a reliable, quantifiable, nondestructive means, instead of using other unreliable methods or overly conservative estimates that result in higher inspection and repair costs.


In this study, the optimal isolation system for the explosive gas operated device (EGOD) was investigated. Based on the analysis of the human body response induced by impulsive disturbances from the EGOD and the simplified human interaction model, a feasible isolation scheme has been presented and the prototype isolation system including the dynamic absorber has been constructed. In order to determine the parameters of that system, an optimization process was performed under constrained conditions. Finally, the performance of the designed prototype isolation system was evaluated in a series of experiments under actual utility condition, and the transmitted force from the EGOD to human body was predicted.


The Hirudinea have a number of arthropod-like characters, including a true haemocoel and compound eyes. This 'arthropodization' may have bearing on the origin of the arthropod phylum Uniramia. Certain traits shared by Clitellata and Uniramia are interpreted as primitive and compatible with the view that a monophyletic link exists between these two groups: 'internal' fertilization, egg protected by cocoon/chorion, egg yolky with direct development not invoking a planktotrophic larval stage, formation and fate of presumptive areas in early embryology, uniramous lobopodial-like structures and the presence of uniramous mouthparts. Still other traits shared by Hirudinea and Hexapoda are interpreted as advanced and evidence for a paraphyletic relationship between leeches and pterygote insects: oogenesis with nurse cells, cephalization and segmental constancy. It is proposed that a major theme in uniramian evolution is the invasion of land from freshwater by a pre-lobopodial clitellate-like ancestor, the lobopodium being an adaptation to terrestrial locomotion. These views give new significance to the poorly studied fossil segmented worms from freshwater and terrestrial palaeohabitats.


Growing evidence has shown that the elderly population is more susceptible to postoperative cognitive dysfunction/decline (POCD). It has been proven that dexmedetomidine can reduce postoperative cognitive function impairment in elderly patients. Whether dexmedetomidine is better than midazolam in reducing incidence of POCD in elderly surgical patients, however, remains unknown. A total of 198 surgery patients (non-cardiac and non-neurosurgery) were enrolled in the current study. A total of 98 patients (DEX group) received a dose of 0.5 ug/kg dexmedetomidine before the induction of general anesthesia. Another 100 patients (MZ group) received midazolam 0.05 mg/kg. Serum samples of S100β protein levels were determined immediately before the application of dexmedetomidine or midazolam and 1 hour after surgery. The Mini Mental State Examination (MMSE) was evaluated at the day before surgery, 5-7 days postoperative, and 3 months postoperative. Results showed that, at 5-7 days after surgery, 52 (26%) patients experienced POCD, with 24 (24.5%) in the DEX group and 28 (28.0%) in the MZ group (24 VS 28, P = 0.575). Three months after surgery, 132 patients accepted the MMSE test, with 16 (12.1%) of them experiencing POCD, including 9 (12.9%) in the DEX group and 7 (11.7%) in the MZ group (9 VS 7, P = 0.783). Increased levels of S100β protein were higher in the MZ group than DEX group (100.68 ± 94.37 pg/mL VS 51.33 ± 88.78 pg/mL, P < 0.001). Logistic regression analysis showed that postoperative pneumonia (incidence of postoperative pneumonia in POCD group VS non-POCD group was 0.12 ± 0.32 VS 0.08 ± 0.28 respectively, P = 0.041), lower preoperative MMSE scores (22.83 ± 3.49 VS 25.55 ± 3.27, P < 0.001), and increased levels of S100β (134.80 ± 81.63 VS 55.40 ± 90.41, P < 0.001) were risk factors of POCD occurring within 5-7 days after surgery. Age was included in the risk factors of POCD occurring within 3 months postoperative (71.56 ± 4.35 VS 69.22 ± 4.29, P = 0.031), except for lower preoperative MMSE scores (24.75 ± 3.53 VS 25.94 ± 2.96, p = 0.001) and increased levels of S100β (92.08 ± 74.12 VS 69.70 ± 95.84, P = 0.002). Present results indicate that dexmedetomidine can reduce neuronal injuries but can't reduce incidence of POCD in the elderly, compared with midazolam. Risk factors for POCD occurring at different postoperative periods are different. Age is a potential risk factor of long-term POCD, but not for early POCD in the elderly.


Summary Itisgenerally believed that ascertainment corrections areunnecessary inlinkage analysis, provided individuals areselected forstudy solely onthebasis oftrait phenotype andnotonthebasis ofmarker genotype. Thetheoretical rationale forthis isthat standard linkage analytic methods involve conditioning likelihoods onall thetrait data, whichmaybeviewed asanapplication ofthe ascertainment assumption-free (AAF) method ofEwens andShute. Inthis paper, weshowthat whentheobserved pedigree structure depends onwhichrelatives within apedigree happen tohavebeentheprobands (proband-dependent, orPD,sampling) conditioning on all thetrait dataisnotavalid application oftheAAF method andwill result inasymptotically biased estimates ofgenetic parameters (except under single ascertainment). Furthermore, this result holds eveniftherecombination fraction Ristheonly parameter ofinterest. Since thelodscore isproportional tothelikelihood of themarker dataconditional onall thetrait data, this means that whendata areobtained under PDsampling thelodscore will yield asymptotically biased estimates ofR,andthat so-called modscores (i.e., lodscores maximized over bothRandparameters 0ofthetrait distribution) will yield asymptotically biased estimates ofR and0.Furthermore, theproblem appears tobeintractable, inthesense that itisnotpossible toformulate the correct likelihood conditional onobserved pedigree structure. Inthis paper wedonotinvestigate thenumericalmagnitude ofthebias, which maybesmall inmany situations. Ontheother hand, virtually all linkage data sets arecollected under PDsampling. Thus, theexistence ofthis bias will betherule rather thantheexception in theusual applications.

Abstract In the limiting case of Sobolev-Adams theorem for Morrey spaces of variable order we prove that the fractional operator of variable order maps the corresponding vanishing Morrey space into VMO.


Background The pathogenesis of posterior papillary muscle dysfunction is poorly understood. We hypothesized that papillary muscle perfusion pattern may explain the higher prevalence of posterior papillary muscle dysfunction after myocardial infarction. Methods and Results Twenty patients were monitored by transesophageal echocardiography during coronary surgery. Superselective coronary graft injections of 0.2 to 0.5 mL of sonicated albumin microbubbles were performed to assess graft patency and papillary muscle perfusion. Thirty-five graft injections were analyzed: 13 in the right coronary artery, 15 in an obtuse marginal branch, 1 in the left anterior descending coronary artery, and 6 in the first diagonal branch. The posterior papillary muscle was opacified in 16 patients, 11 from the right coronary artery and 5 from one obtuse marginal branch. In 10 of 16 patients (63%), the papillary muscle was perfused by one vessel, while in 6 of 16 (37%), it was perfused by two vessels. The anterior papillary muscl...

Faraday cages have traditionally been used to provide isolation from electromagnetic fields. In this paper, we describe the use of Faraday cages for reducing crosstalk in 3D ICs. We validate our methodology with a combination of simulation and measurements from fabricated prototype designs. Measurement and simulation results show that the crosstalk between the transmitter and receiver reduces by about 75 dB up to 10 GHz by using a Faraday cage in combination with tier-to-tier isolation, which is one of best performance reported so far. We further develop a lumped equivalent model for crosstalk with and without a Faraday cage. There is good agreement between measurement, 3D electromagnetic simulation and lumped circuit simulation.


ABSTRACT The Developmental Coordination Disorder Questionnaire (DCDQ'07) is a Canadian-English instrument recommended for screening children aged 5 to 15 years who are at risk for developmental coordination disorder. While a Canadian-French version of the DCDQ'07 presently exists, a European-French version does not. Aims. To produce a cross-cultural adaptation of the DCDQ'07 for use in areas of Europe where French is spoken and to test its cultural relevance in French-speaking Switzerland. Methods. Cross-cultural adaptation was done using established guidelines. Cultural relevance was analyzed with cognitive interviews of thirteen parents of children aged 5.0 to 14.6 years (mean age: 8.5 years, SD = 3.4), using think-aloud and probing techniques. Results. Cultural and linguistic differences were noted between the European-French, the Canadian-French, and the original versions of the DCDQ'07. Despite correct translation and expert committee review, cognitive interviews revealed that certain items of the European-French version were unclear or misinterpreted and further modifications were needed. Conclusions. After rewording items as a result of the outcomes of the cognitive interview, the European-French version of the DCDQ'07 is culturally appropriate for use in French-speaking Switzerland. Further studies are necessary to determine its psychometric properties.


Three unsymmetrical intercyclic olefins, their dibromides, and their pinacols were prepared, each so the two carbons involved at the functional group were part of a different sized ring. The pinacols were reacted with 25% sulfuric acid and with boron trifluoride etherate, the dibromides with silver nitrate, and the olefins with mercuric acetate and with trifluoroperacetic acid. The predominant spiro ketone found in each product mixture was used to determine which carbon, and hence which size ring, could better undergo the sp 3 to sp 2 or the sp 2 to sp 3 transition. The findings were consistent with Brown's observations on ring strain

ABSTRACT Most eukaryotic centromeres are located within heterochromatic regions. Paradoxically, heterochromatin can also antagonize de novo centromere formation, and some centromeres lack it altogether. In order to investigate the importance of heterochromatin at centromeres, we used epigenetic engineering of a synthetic alphoidtetO human artificial chromosome (HAC), to which chimeric proteins can be targeted. By tethering the JMJD2D demethylase (also known as KDM4D), we removed heterochromatin mark H3K9me3 (histone 3 lysine 9 trimethylation) specifically from the HAC centromere. This caused no short-term defects, but long-term tethering reduced HAC centromere protein levels and triggered HAC mis-segregation. However, centromeric CENP-A was maintained at a reduced level. Furthermore, HAC centromere function was compatible with an alternative low-H3K9me3, high-H3K27me3 chromatin signature, as long as residual levels of H3K9me3 remained. When JMJD2D was released from the HAC, H3K9me3 levels recovered over several days back to initial levels along with CENP-A and CENP-C centromere levels, and mitotic segregation fidelity. Our results suggest that a minimal level of heterochromatin is required to stabilize mitotic centromere function but not for maintaining centromere epigenetic memory, and that a homeostatic pathway maintains heterochromatin at centromeres. This article has an associated First Person interview with the first authors of the paper. Summary: Pericentric heterochromatin is dispensable for centromere epigenetic memory, but is required to stabilize centromere protein levels and accurate mitotic segregation. Pericentric heterochromatin levels can also recover after severe depletion.

The said health tea has several health functions.


Strengthening the resource utilization of construction waste can improve the environment, alleviate resource shortage, and build a harmonious ecological environment between man and nature. Prospect theory was integrated into trilateral evolutionary game theory to analyze the processes of resource utilization of construction waste among local government, construction enterprises, and the public by establishing the perceived payoff matrix of the three players in the game and using the replication dynamic equation to analyze their strategy choices and evolution path. The results showed that the strategies of the three players depended on the strategies chosen by the other side, the perceived value of the relevant parameters, and the numerical relations among them. Under the conditions that the local government reasonably controlled the supervision cost and the degree of rewards and punishments, the construction enterprise promoted the resource-based technology and management means, and the public enhanced the sense of social responsibility, the game model would evolve toward the ideal state of (1,1,1), to realize the resource utilization of construction waste.


Success in the software product business requires timely release of new products and upgrades with proper quality and the right features. For this, a systematic approach for managing the contents, timing and roles of future product releases as well as the product architecture is needed. In practice, such an approach is often missing, especially in small companies, due to inexperience, unclear priorities, time-to-market pressures, or the lack of suitable process infra-structure. In this paper, we present a model to visualize product roadmaps developed together with three small software companies and experiences from its use. The model depicts release and development schedules, the composition of individual releases, services that require attention from the developers, changes to the underlying technology and the planned resource usage. We also present lessons learned from the case companies and outline directions for future research.


Web applications are deployed on machines around the globe and offer almost universal accessibility. The systems ensure functional interconnectivity between different components on a 24/7 basis. One of the most important requirements represents data confidentiality and secure authentication. However, implementation flaws and unfulfilled requirements can result in security leaks that can be eventually exploited by a malicious user. Here different testing methods are applied in order to detect software defects and prevent unauthorized access in advance. Automated planning and scheduling provides the possibility to specify a specific problem and to generate plans, which in turn guide the execution of a program. In this paper, a planning-based approach is introduced for modeling and testing of web applications. The specification offers a high degree of extendibility and configurability but overcomes the limits of traditional graphical representations as well. In this way, new testing possibilities emerge that eventually lead to better vulnerability detection, thereby ensuring more secure services.


Background Giardia duodenalis is one of the most important human enteric parasites throughout the world. Clinical symptoms of this parasite vary from asymptomatic infection to chronic diarrhea. Still it is not clear, whether different types of pathogenesis are due to different strains of organism or to variable host factors. The purpose of this study was to investigate possible correlation of clinical symptoms with assemblages among symptomatic and asymptomatic cases collected from southwest of Iran. Methods Fecal samples were collected from 100 symptomatic and asymptomatic cases, which were positive for G. duodenalis. The samples were subjected to semi-nested PCR and RFLP for gdh gene. Results Among symptomatic patients, 54% had mixed genotypes AII and BIII, 28% and 18% of samples indicated assemblages BIII and AII, respectively. In contrast, among asymptomatic cases, 64%, 26% and 10%samples had mixed genotypes, BIII and AII assemblages, respectively. Statistical analysis using Chi- Square test showed that there was no significant correlation between assemblage and clinical symptoms in current study. Conclusion High prevalence of mixed infection in both groups may affect this conclusion, therefore further study in more details are necessary to clarify these finding. Additionally, it is important to carry out investigations regarding human host factors as well.


Pantothenoylcysteine-4′-phosphate decarboxylase has been purified 700-fold from horse liver by by an improved method. Enzyme activity was determined by measuring the amount of labeled CO2 produced from the labeled cysteine moiety of the substrate molecule. The enzyme is not bound to any cellular structure since more than 80% of the total activity of the homogenate is recovered in the supernatant fraction. The enzyme does not seem to contain pyridoxal phosphate, is strongly inhibited by this latter and by carbonyl reagents, such as sodium borohydride, hydroxylamine and phenylhydrazine. These findings strongly support the presence in the enzyme molecule of a reactive carbonyl group. The enzymic reaction rate is increased over 20-fold by sulfhydryl compounds, has an absolute specificity for pantothenoylcysteine 4′-phosphate and is not inhibited either by pantothenoylcysteine or by the reaction product, pantetheine 4′-phosphate.


The present study was designed to evaluate the anthelmintic activity of water-soluble extracts of fresh calyces of Hibiscus sabdariffa (Malvaceae) using Lumbricus terrestris as a test worm. The worms were exposed to water extracts of different concentrations of H. sabdariffa (6.25, 12.5, 25, and 50 mg/ml) and the times of paralysis and death of the worms were recorded. Vermox was used a positive control and distilled water was used as a negative control.


The effect of finite nuclear dimensions on the angular distribution of longitudinally polarized electron-positron pairs formed by circularly polarized gamma quanta in a nuclear field was investigated. The derived cross section formula contains spin correlation terms, considering mean square radius of the nuclear charge, in addition to the BetheGaitler cross sections. (R.V.J.)


We describe a new sequential learning scheme called "stacked sequential learning". Stacked sequential learning is a meta-learning algorithm, in which an arbitrary base learner is augmented so as to make it aware of the labels of nearby examples. We evaluate the method on several "sequential partitioning problems", which are characterized by long runs of identical labels. We demonstrate that on these problems, sequential stacking consistently improves the performance of nonsequential base learners; that sequential stacking often improves performance of learners (such as CRFs) that are designed specifically for sequential tasks; and that a sequentially stacked maximum-entropy learner generally outperforms CRFs.


In order to determine the abundance of incoming year classes of both mackerel and horse mackerel a couple of research vessels in the frame of ICES investigats waters west of the British Isles, the Gulf of Biscay and areas west of the Iberian Peninsula in the first half of each third year. In 1995, Germany took place in these investigations with R.V. "Walther Herwig III" from March 23 to April 18. A total of 100 plankton stations were made using a Gulf - III - Sampier between Fastnet Rock and
the Gironde estuary. In addition, 87 fishing stations were occupied by a GOV net. Though fish indications were not fished on purpose large amounts of especially horse mackerel and mackerel were gained in the half hour tows. Besides, boarfish (Capros aper L.), blue whiting, and sprat were found in considerable quantities and numbers in some areas. The hydrographc situation was as expected: The development of a surfaee thermocline created by radiation indieates the collapse of the vertically homogeneous situation of the winter period.


The in vitro growth of virus-free sweet potato [Ipomoea batatas (L.) Lam.] plantlets was investigated under different light sources: fluorescent lamp (control); red (660 nm), blue (460 nm), white light-emitting diodes (LED), and two mixtures of blue and red LED (R:B = 8:2, and 7:3). Single node explants (10 mm) of three cultivars ('Matnami', 'Shincheonmi', and 'Yeonhwangmi') were cultured on Murashige and Skoog medium supplemented with 0.2mg·L 6-benzyladenine for 4 weeks. Explants were exposed to 150 ± 5 μmol·m·s photosynthetic photon flux at a distance of 20 cm, constant temperature of 25°C, and under 16/8-h (day/ night) photoperiod. Using the same method, the in vitro growth of 10 cultivars under red LED was also compared. After 3 weeks, vine length was highest in plantlets cultured under red LED, and lowest in plantlets cultured under blue LED. Fresh and dry weights were also greatest in plantlets cultured under red LED. Compared to the control, vine thickness was significantly higher in plantlets grown under white LED and the 7:3 R:B LED mixture. Significant differences were observed among the 10 cultivars grown under red LED. 'Matnami', 'Shincheonmi', and 'Shinhwangmi' all had excellent vine lengths, and fresh and dry weights. Compared to the control, vine elongation of sweet potato plantlets was most effective under red LED, and culture duration was about 1 week shorter.


Starting points to reconsidering the conventional evaluation of accident consequences both from the theoretical as well as the veiwpoint of method have been identified, especially in the following areas: a) Medical treatment costs: In order to survey the medical treatment costs of accident victims, a procedure taking the available data material into consideration and discriminating between treatment costs to a greater extent than given by the classification into major and minor injuries would be desirable. The ICD based flat rate per case might be primarily considered in this context. b) Costs of disablement: In order to determine the long term costs of disablements resulting from accidents, the determination of permanent accident consequences on the basis of the degree of the functional impairment offers a possibility. Compared with the degree of the reduction of earning capacity, this procedure enables a more realistic classification of the various degrees of long term disabilities. c) Costs of accident fatalities: An alternative to calculating the costs of accident fatalities based on the value-added method or cost value rating is offered by the willingness-to-pay-method. This method which is still not widely used, at least not in the German speaking countries, attempts to determine the value of human life based on market observations and interview studies. The sophisticated instruments developed on the environmental economy sector suggest carrying out empirical studies also on the sector of road accidents.


The increased commission of sex crimes in Iran highlights the need for more efforts to design strategies towards prevention and reduction of such crimes. Accordingly, the present research aimed to identify the factors affecting the sexual victimization of children and adolescents as well as to identify the personality characteristics of sex delinquents in the criminal justice system of Iran. The research method is mixed design in terms of data nature (qualitative and quantitative) and practical in terms of purpose. The qualitative section has reviewed the previous literature and the quantitative section has benefited from the analytic hierarchy process (AHP). This research has used the opinions of 13 experts in the field of crimes against children and adolescents, and 43 sex offenders. The research findings led to the identification of six factors (social, economic, psychological, legal, executive, media) that are effective on the prevention and postvention of sexually abused children and adolescents in Iran. The highest rank is related to the economic and social factors, and the lowest rank is related to the media factors. The results of this study showed that the identified parameters are approved by experts and have theoretical support that can be effective in reducing sexual delinquency.


A new Polish project, the first to be carried out in Ethiopia by the PCMA University of Warsaw, focused on the excavation of the ruins of a church tentatively dated to the Late Aksumite period (6th–8th centuries AD). The site, which is located in the northern region of Tigray in Ethiopia, was chosen for multiple reasons, not the least because of its location on ancient trade routes and because the surviving ruins offered the advantage of immediate visual impact. The work was unexpectedly interrupted by the global Covid-19 pandemic and recent political turbulences in the Tigray region. The paper discusses the early findings, providing, among others, a full description of the PolART excavations in the southeastern part of the church and the discovery of a rock shelter with ancient inscriptions and painted pictograms.


Amorphous Bi:YIG film was deposited on Si substrates by radio frequency (RF) magnetron sputtering and crystallized by recurrent rapid thermal annealing (RRTA) method.The effects of heating temperature on the crystallization,the surface condition and magnetic properties of the films were studied using X-ray diffraction,atom force microscope and vibrating sample magnetometer,and the effects of atmosphere and the recurrent period on the films were also concluded.The results show that the film with good magnetic properties which saturation magnetization 139 kA/m and coercive force 6.37 kA/m and good surface conditions are obtained by RRTA method in same time,and the Faraday angle on quartz substrate treated by RRTA method doubles of samples treated by common thermal annealing method.


HIL test is an important part in the development of the aero-engine control system. In order to meet the engineering requirements, how to establish the real-time fault simulation models of the control system is an essential problem for HIL. This paper proposes a simulation model with general architecture based on the Simulink platform of the HIL system, which can realize the function of fault simulation. The EEC sends out warning or fault signals according to the detected information, so as to verify the correctness of the EEC control strategy and fault diagnosis function. In this paper, the frequent faults in the engine control system are simulated and verified, which can guide the design and test of the control strategy.

The behavior of a bubble plume discharging vertically into a stably stratified water column is described using a simple one-dimensional plume model. It is confirmed that the behavior can be described with just two dimensionless groupings, C and M, representative of the strength of the stratification and the discharge momentum. Depending on the values of these parameters, the plume can either extend the full depth of the water column or eject water at one or more internal detrainment points. The occurrence of these internal detrainment points can be described in terms of the relative magnitudes of the terms comprising the buoyancy conservation equation. Further, these internal detrainment points can be linked to both the mechanical efficiency and mixing effectiveness of bubble plumes. This is of importance when the bubble plume is being used to act as a destratification device in a lake. Generally, an integral number of internal detrainment points correspond to peak mechanical efficiencies. Maximum mixing effectiveness is favored by lower values of the stratification parameter C and higher values of the source strength parameter M.


How do educators prepare the next generation of adults and leaders in an era of radical climate disruption, ecological tipping points, economic volatility, and social and political inequity? In other words, should there be a new type of education for a dystopian future? Although the world has never been a stable, serene place, the changes to the Earth globally and the social disruptions happening in this second decade of the twenty-first century are unprecedented and alarming. The present epoch has been called the Anthropocene, a time of human domination of the Earth. This new epoch requires educators to completely rethink the purpose and goals of education, especially in terms of preparing young people for a viable and hopeful future.


This article develops a psychology of love that integrates a Roman Catholic understanding of the personin-relationship and fmdings of secular psychology. It demonstrates the dynamics of the virtue of love (as an act of love, a disposition to love, and the command to love) that demands attention to biophysical, psychosocial, and spiritual levels of relationships, emotion, cognition, and freewill. It indicates that love has a role to play in therapy with those in need of treatment, especially couples, families, and special populations. Numerous therapeutic challenges to love exist, including: transcending self, love of self, and love of enemies. This focus on therapy incorporates science and philosophy but also requires something greater, namely Christ's gift of grace and revelation. While this gift remains dependent on God, therapists and clients are called to bear loving witness to it and to God, not only in the therapeutic relationship, but also in all their vocations and life work.


Unlike tremendous works on the electronic structures of tetradymite compounds, studies of their thermal properties are relatively rare. Here, first-principles calculations and Boltzmann theory are combined to investigate the phonon transport of such kind of layered materials. Using four binary tetradymites as prototypical examples, it is interesting to find that the weak van der Waals (vdW) interactions play an important role in determining their lattice thermal conductivities, which are obviously higher than those without the consideration of vdW, especially for the out-of-plane direction. In principle, such enhanced phonon transport can be attributed to the decreased interlayer spacing caused by the presence of vdW, which effectively reduces the strong anharmonicity of the systems. Indeed, we observe relatively smaller Grüneisen parameter together with larger phonon group velocity and relaxation time. Our theoretical work demonstrates the vital importance of the seemingly weak vdW forces in predicting the phonon transport properties of various layered structures.

In the human experience the main values in the supply system are results of strong cultural, economic, social and environmental conditioning and of cultural processes; the act of feeding represents clearly a behavior – language and the single food are the words. What does it means then, in the third millennium, to support the belief that food is synonym of culture? Does is it still make sense to talk about a one supply culture in a always more complex and differentiated background for style of consume and multiethnic composition?


Based on the PSR conceptual evaluation model of urban green and low-carbon development competitiveness, this paper evaluates the green and low-carbon development competitiveness of 13 cities in Beijing-Tianjin-Hebei from 2010 to 2019 and reveals their spatial effects and obstacle factors combined with the spatial autocorrelation and obstacle model. The results show the following: (1) In terms of the overall situation, the evaluation index of urban green and low-carbon development competitiveness in the Beijing-Tianjin-Hebei region shows a fluctuating upward trend as a whole from 2010 to 2019. Among them, the comprehensive evaluation indexes of Beijing, Zhangjiakou, and Tianjin are very competitive, while Hengshui, Handan, and Xingtai are relatively weak. (2) In terms of spatial data analysis, the global and local Moran`s I of Beijing-Tianjin-Hebei cities from 2010 to 2019 were positive and passed the 1% significant level test. This shows that the comprehensive evaluation index of urban green low-carbon development competitiveness of Beijing-Tianjin-Hebei cities has a positive spatial correlation, and the spatial agglomeration effect is significant. On the whole, it presents a spatial agglomeration pattern of "high in the north, partial jump, and low in the south". (3) In the aspect of obstacle factor analysis, the proportion of the tertiary industry output value in GDP, energy consumption of ten thousand yuan of GDP, the urban green technology innovation level, and industrial soot emission of ten thousand yuan of GDP are the main obstacle factors restricting the improvement of urban green low-carbon development competitiveness in Beijing-Tianjin-Hebei cities.


We can't deny the awkwardness and attention-seeking antics of our teenage years. From fixations on the body to fashion, self-loathing, the desire for validation and wondering if the person you like even notices you, each layer of angst further adds to the collective consciousness of what Kate Durbin has coined as "teen girl Tumblr aesthetic." A particular look and feel has arisen over the years with the ability to turn the gaze back onto one's self and frame, re-frame, mediate, and remediate one's life through the mobile phone lens. Durbin's work explores the amalgamation of pop culture, the reversal of the gaze onto one's self, and networked culture's effect on public performance through her recent work Hello Selfie. Durbin was kind enough to answer questions about her artistic practice via email. The following is a transcript of the exchange. Dorothy Santos (DS): I'll start with the Women as Objects project, since it was one of the works that drew me into your artistic practice. The work seems heavily based on American young women. But the Internet enables us to explore a vast array of mediations and re-mediations of femininity. When you came up with the term "teen girl Tumblr aesthetic," what commonalities or connections did you find in your research across cultures and subcultures? Kate Durbin (KD): I did, although I maintain this was a curatorial project, not a research project. There are many aesthetic intersections between female-identifying users in the U.S. and in Asian countries, in particular. A lot of gothic Lolita, cute or Kawaii references make sense, given Lolita fashion in Japan was originally a mishmash of Western influences. Hello Kitty, as we now know, is not only a cat, but a British schoolgirl. The teen girl Tumblr aesthetic is very much a mixture of global capitalist girl culture references, sliced and diced and glitterfied by girls in places with net access and enough money and time to get online. DS: This leads me to ask about your project Girls, Online for the online art gallery, Bright Stupid Confetti. It's strange because when I looked through the collection, the inanimate objects were much more resonant and striking as performing girl-ness or femininity. While the work was done in 2012, the photography, the illustrations, and .gifs continue to reflect contemporary girl culture online. How did you go about selecting the works for this project, considering that they are based on an "art of the moment" approach?

In the report "Guidance for Assessment of Poliovirus Vaccination Status and Vaccination of Children Who Have Received Poliovirus Vaccine Outside the United States," on page 24, under the section "Children with documentation of poliovirus vaccination." the first paragraph should have read as follows: Previous poliovirus vaccination is valid if documentation indicates receipt of IPV or tOPV. tOPV was used for routine poliovirus vaccination before April 1, 2016 in all OPV-using countries. Therefore, if a child has documentation of receipt of an OPV dose (rather than "tOPV") before April 1, 2016, this represents a tOPV dose and should be counted towards the U.S. vaccination schedule, unless specifically notated that it was administered during a vaccination campaign.* Consistent with the polio eradication strategy, doses of OPV administered on or after April 1, 2016 are either bOPV (used in routine vaccination and campaigns), or mOPV (used in a type-specific outbreak response); these doses do not count towards the U.S. vaccination requirements for protection against all three poliovirus types. Persons aged <18 years with doses of OPV that do not count towards the U.S. vaccination requirements should receive IPV to complete the schedule according to the U.S. IPV schedule.

Tight integration of experimental study, mathematical analysis and numerical simutation is extremely helpful in the study and systematic development of energy process-engineering plants and processes. This tight integration is a basic working principie at the Chair for Energy Systems and Energy Process Technology (LEAT). The continuously expanded, modern mensurational and numerical methods used permit ever more efficient treatment of complex problems in this context The leadership of LEAT was transferred from Professor Hans Kremer to Professor Viktor Scherer on March 1, 2000. In the tradition of the Chair, the previous focuses are being incensified and pursued further. They include, inter alia, experimental and numerical flow and mixing studies on burners and power-plant boilers, the study of pulverized-coal combustion systems under atmospheric conditions and under elevated combustion pressure. Other toics include combustion in recirculating fluidized beds, the optimization of calcining systems in cement kilas, the conversion of fossil fueis in chemicals industry plants, and optimization of glass-melting furpaces. A recently added emphasis is the study of low-pollatant combustion of natural gas and liquid fuels in gas turbines for power generating applications. In addition, mathematical modelling of energy-engineering processes is also to be extended to the optimization of complete plants.


The development of entrepreneurship among peasants of Tula region in post-reformed Russia is considered in the following article. The materials have been analyzed to show that village employers not only managed to organize their farming enterprises using the most efficient management, but they used to put their hired laborers to the incredibly intensive work.


Both sexes of a species of Pachnobia have been collected by Mr. Geo Norman, at Orilla, which I propose to call by the name of orilliana. It is evidently allied to Agrotis hyperborea, which I know only from Milliére's and Herrich-Schaeffer's illustrations. It looks at first sight like a species of Graphiphora (Taeniocampa). All the tibiae are spinose. The head is sunken, eyes naked, abdomen short. The wings are wide, the male antennae shortly pectinate, serose. The color is not unlike that of Graph. incerta, but more olivaceous.

Internet of Things plays a vital role in our everyday lives in terms of economic, social, and commercial aspects. The widespread use of IoT devices has made them a prime target for cyber-attacks. IoT botnet attacks usually have a greater sensitivity to the consequences that might result from launching other attacks such as DDoS attacks and dissemination of sensitive information. For botnet detection in the IoT environment, deep learning mechanisms have emerged. But processing high-dimensional data is difficult, and it adversely affects DL-based botnet detection systems. Various dimensionality reduction methods have been proposed by researchers to address this concern. The purpose of this study is to examine and compare current mainstream dimensionality reduction methods. This will enable us to understand how reducing the number of features may lead to higher classification accuracy. Extensive tests are conducted on the NBaIoT dataset to verify the viability of PCA and auto encoder dimensionality reduction strategies. Results show that Auto encoder algorithm outperform PCA dimensionality reduction methods by the accuracy of 95.02%.


Industrial biopolymers produced by microorganisms have become very popular in the oilfield over the last years. Especially Xanthan Gum and Scleroglucan are used extensively as viscosifiers for various drilling fluid applications due to its unique rheological properties. Scleroglucan is known to be more temperature stable than Xanthan Gum. It is distinguished by a better stability against molecular decomposition. Moreover, Scleroglucan offers a better thickening performance at elevated temperatures. This latter aspect is often neglected when temperature stability is discussed. Although the viscosity-behaviour at increased temperature is of decisive importance with regard to downhole conditions. Rheology measurements indicate that Scleroglucan becomes superior to Xanthan Gum even at moderate temperatures of 60 to 80°C (140 to 175°F). At these temperatures and above, Xanthan Gum fluid viscosity drops significantly. Whereas Scleroglucan shows a flat and stable performance profile. This advantage of Scleroglucan first became obvious from a solids settling experiment at 80°C (175°F). It was only the Scleroglucan solution that retained the sized sand particles in suspension. While in the Xanthan Gum solution the solids settled down completely. Surprisingly, from the oilfield-standard FANN 35 SA viscometer this result was not evident. The instrument does not reach the ultra-low-shear range which is most relevant for particle settling. Advanced special instruments are available to cover this However, it turned out, that also a common Brookfield HAT viscometer is very well suited for this purpose. Equipped with a heating cup and rotating at its lowest speed of 0.5 rpm, the instrument provides a simple and reliable approach to trace suspension capacity with increasing temperature. For example, with 2 ppb of Scleroglucan in a CaCl, brine the biopolymer provides a stable Brookfield viscosity of about 20.000 mPas. Whereas with 2 ppb Xanthan Gum it drops down to 5.200 mPas while heating from RT up to 60°C (140°F).

At a future linear collider, a polarized electron beam will play an important role in interpreting new physics signals. Backgrounds to a new physics reaction can be reduced by choice of the electron polarization state. The origin of a new physics reaction can be clarified by measuring its polarization-dependence. This paper examines some options for polarimetry with an emphasis on physics issues that motivate how precise the polarization determination needs to be. In addition to Compton polarimetry, the possibility of using Standard Model asymmetries, such as the asymmetry in forward W-pairs, is considered as a possible polarimeter. Both e+e- and e-e- collider modes are considered.


The recent appearance of the Third Catalogue of Spectroscopic Binary Stars containing in substance all available data relating to thé orbits of these objects and the fact that numerous additions have been made within the last few years to the number of visual binary star orbits, seem to make it worth while to review once more the relations between the orbit elements, though the many investigations along these lines made since those by Campbell and Schlesinger in 1910 have in general altered their conclusions only in minor details. The present investigation is based upon the orbital elements of 226 spectroscopic binaries and 103 visual binaries for which we have more or less well determined orbits. Of the 248 stars for which elements were listed in Table III of the Third Catalogue we have excluded from our consideration the 19 Cepheid variables, and the following stars : ß Canis Majoris, 12 Lacertœ, a Canis V enaticorum, y Ursœ Mino ris, y G entino rum, o Ceti, a Orionis, and a S cor pii. In our judgment, there is good reason for doubting the true binary character of some of these stars, and the orbital elements of the others obviously need revision. We have utilized in our discussion the two sets of elements furnished by each of the five triple systems, ß Per sei, fi Orionis, VV Orionis, ß Coronœ Borealis and a Scorpii. Attention has frequently been called to the fact that among binary stars the eccentricity in general increases with the length


Lernaeenicus ramosus Kirtisinghe, 1956 is redescribed on the basis of metamorphosed females recovered from the body surface of Epinephelus akaara (Temminck & Schlegel, 1842) (Pisces, Serranidae). Also the male, copepodid I, both sexes of chalimus II and III, and chalimus IV male were recovered, together with the females, from the branchial lamellae of the same host and are herein described for the first time for the species. The developmental process of leg 4 in L. ramosus differs from that in L. sprattae (Sowerby, 1806).


We reported on high average power ultraviolet (UV) picosecond optical vortex generation without any spatial separation of the phase singularity due to the walk-off effect by employing a pair of β-BaB2O4 and reversed β-BaB2O4 crystals. The UV vortex output power was measured to be 1.76 W, corresponding to the optical-optical conversion efficiency of 17 %.


Analytic expressions are derived for the evaluation of derivatives of the total molecular energy with respect to external parameters ~nuclear coordinates, external electric fields, etc.! within the relativistic regular approximation. The presented formalism employs the spectral resolution of the identity avoiding, however, the explicit use of an auxiliary basis set in the calculation of the matrix elements of the regular relativistic Hamiltonian. The final formulas for the total energy and energy derivatives are presented in matrix form suitable for implementation into standard quantum chemical packages. Results of benchmark calculations for gold containing diatomic molecules and for xenone hexafluoride performed at the Hartree‐Fock and various correlation corrected levels of theory are presented and discussed. © 2003 American Institute of Physics. @DOI: 10.1063/1.1561046#


We report results from a high-resolution numerical study of fluid particles transported by a fully developed turbulent flow at R λ = 280. Single-particle trajectories were followed for a time range spanning more than three decades, from less than a tenth of the Kolmogorov timescale up to one large-eddy turnover time. We present results concerning acceleration statistics and the statistics of trapping by vortex filaments conditioned to the local values of vorticity and enstrophy. We found that a suitable observable, a ⊥ = a × v, connected to the centripetal acceleration, is strongly sensitive to the trapping of particles into vortex filaments. In particular, we found that its sign may persist up to 10–15 τη, while the typical oscillation of the longitudinal acceleration happens on a time lag of a few τη.


Accurate polyp detection is essential for assisting clinical rectal cancer diagnoses. Colonoscopy videos contain richer information than still images, making them a valuable resource for deep learning methods. Great efforts have been made to conduct video polyp detection through multi-frame temporal/spatial aggregation. However, unlike common fixed-camera video, the camera-moving scene in colonoscopy videos can cause rapid video jitters, leading to unstable training for existing video detection models. Additionally, the concealed nature of some polyps and the complex background environment further hinder the performance of existing video detectors. In this paper, we propose the \textbf{YONA} (\textbf{Y}ou \textbf{O}nly \textbf{N}eed one \textbf{A}djacent Reference-frame) method, an efficient end-to-end training framework for video polyp detection. YONA fully exploits the information of one previous adjacent frame and conducts polyp detection on the current frame without multi-frame collaborations. Specifically, for the foreground, YONA adaptively aligns the current frame's channel activation patterns with its adjacent reference frames according to their foreground similarity. For the background, YONA conducts background dynamic alignment guided by inter-frame difference to eliminate the invalid features produced by drastic spatial jitters. Moreover, YONA applies cross-frame contrastive learning during training, leveraging the ground truth bounding box to improve the model's perception of polyp and background. Quantitative and qualitative experiments on three public challenging benchmarks demonstrate that our proposed YONA outperforms previous state-of-the-art competitors by a large margin in both accuracy and speed.


This paper presents two series of tests on steel beam to concrete filled steel tubular (CFST) column connections and repaired concrete-filled steel tubular connections after exposure to the ISO-834 standard fire. Each test specimen consisted of a CFST column and two steel beam segments connected by external rings to the CFST column on each side to represent an interior joint in a building. The test parameters included the column cross-sectional type, the level of axial load in the column, the beam-column strength ratio and the fire duration time. The applied load in the column was a constant axial load followed by a cyclical lateral load (applied via the connected beams) with increasing amplitude until failure. It was found that the composite joints after exposure to fire exhibited very high levels of energy dissipation and ductility. The tested results were verified by a nonlinear finite element analysis (FEA) model developed by the authors. Comparisons between the test and finite element simulation results show good agreement, which enable the finite element model to be applied in further research studies of the earthquake-resistant behavior of retrofitted fire damaged concrete-filled steel tubular structures.


In plant industry, sulfur storage tank is made of steel and annular plate is connected with concrete foundation of ring wall type by anchor bolt. Due to keep sulfur at high temperature in tank by coil, sulfur storage tank is expanded larger than another tank stores fluid at room temperature. Generally, structural design of tank foundation is performed analysis with loading of temperature gradient between inner and outer surface, this method can't consider the phenomenon that load is intensively transferred to concrete foundation at anchor bolt. This means that temperature load is underestimated and causes crack of concrete near anchor bolt. In this study, evaluation formula considering temperature load transfer mechanism through anchor bolt is proposed and load acting on concrete foundation is rationally decided. For this purpose, it is analyzed variation of thermal load per various anchor bolt number using finite element model including tank annular plate and anchor bolt. Solution is proposed as specified term combining result of analysis and theoretical solution for evaluating load transferred by anchor bolt. For confirmation of validation of proposed formula, it is applied in design of sulfur storage tank at plant site, it shows that the formula can be practically applied.


Attending regional economic cooperation is an important path of economic development of transition countries.Now transition countries hardly have strategic arrangement of attending regional cooperation,the integration level of their regional cooperation is low.Therefore transition countries should establish special institution to strengthen the research and arrangement of regional economic cooperation.First,transition countries should strengthen the cooperation with neighboring countries.Second,transition countries should select the strategic and friendly countries in the whole world to cooperate.


Factors affecting the thermal degradation rate of anion exchange resin were discussed by static immersion test,such as temperature and water-resin ratio(soak solution and resin quality ratio).The results showed that,the degradation reaction followed the zero-order kinetics well when the water-resin ratio was not higher than 200∶6within temperature range from 60 ℃to 80℃.Strong-base loss rate increased with the temperature and water-resin ratio.In addition,static immersion test should try to eliminate the effect of water-resin ratio,which will make the heat resistance results reflect and guide the actual production better.

Real-time operation of Distribution Systems (DSs) demands the processing of a large volume of data in order to obtain the estimated state of the network. Accuracy and efficiency are requirements of the state estimation process which not only obtains the state variables but also detects gross errors in the input data. DSs may present ill-conditioning which badly affects the traditional WLS estimator and in this work an orthogonal formulation is presented so that the estimated state, as well as the processing of gross errors, are done using an computationally efficient and numerically robust method. Simulations are performed using three-phase IEEE test feeders and the results show that the detection of gross errors is effective with this orthogonal formulation. Sparse techniques are used to increase computational efficiency.


Summary

All these cases, as we have pointed out, were treated according to the following routine, which we believe, gives the best results-namely, cystostomy immediately following the accident, followed by perineotomy a month later. This interval allows a period of rest, and an opportunity for disinfection of the bladder and the traumatized area, and the reconstruction of the urethra. Special interest, we consider, attaches to this line of treatment for complete rupture of the urethra, with regard to the following points:

1. The time of the intervention.

2. The subsequent perineal catheter.

3. The disinfection and care of the case, between operations.

4. The closing of the cystostomy.

The operation to divert the urine should follow immediately after establishing the diagnosis, and by this means extravasation into the perineum will be avoided. A catheter may be placed in position if necessary, once the perineotomy has been done. For this, one should use a No. 16 Charritre catheter, adopting the technique of Fey and Hortolmey. The thorough cleansing of the bladder and the efficiency of the catheter are indispensable, if a good result is to be obtained.

Rarely it may be necessary to continue urethral dilatation with metal sounds, after the end of hospital treatment.

The evidence afforded by urethrography is invaluable as is clear from the reported cases; for example the course, permeability, and other features of the damaged portion of the urethra are made clear.

Published just in time to be distributed at the Eudora Welty Centenary Conference in Jackson this past April (2009), the Eudora Welty Centennial Supplement of the Mississippi Quarterly throws down the gauntlet to critics who have dismissed Welty as conservative, provincial, genteel, and nostalgic. The nine essays collected here by guest editor Pearl Amelia McHaney celebrate a writer far more daring and experimental than the diffident and politically disengaged spinster/obedient daughter portrayed by critics and journalists like Carolyn Heilbrun, Ann Waldron, and Claudia Roth Pierpont. Rather, the figure of Eudora Welty that emerges in these essays, as in the updated scholarly checklist from 1986 to 2008 and the long chronology of awards and honors won over her career, reveals a writer of dazzling narrative gifts, thoroughly engaged with her world's most vexing political and philosophical issues and with the most experimental and avant-garde currents of twentieth-century literature and art. These essays together also do a real service in pointing out new directions being taken in Welty studies, especially in topics related to gender and sexuality, performance studies, critical race theory, memory, and postmodernism. Above all, what these essays argue is that Welty scholars have a great deal of work to do in reconstructing the cultural context of Welty's fiction and nonfiction, whether that context be the culture of segregation in which she lived most of her life or the avant-garde art of Britain and Europe with which she quietly but firmly allied herself. The most successful of the essays here arguing for Welty's adventurous and adversarial credentials—by Tenley Gwen Bank, Deborah Clarke, Rebecca Mark, Suzanne Marrs, David McWhirter, Dina Smith, and Danièle Pitavy-Souques—are also those that are most interdisciplinary and the most willing to venture far afield from the more conventional corridors of literary criticism. Indeed, Marrs suggests in the issue's opening essay, which serves as an introduction of sorts, that modernist art provided Welty with something like an adversary vocabulary for articulating the rage that Mississippi politics, embodied by the likes of Theodore Bilbo


Human hepatitis B virus X protein (HBx) is associated with the induction of oxidative stress, which is considered significant in the development of liver damage. In this study, we investigated the molecular mechanisms by which HBx induced lipid peroxidation and tumor necrosis factor-a (TNF-a) expression through regulation of selenoprotein P (SeP) expression in the human hepatoma cell line, HepG2. Forced expression of HBx significantly down-regulated the expression of SeP mRNA and protein in both the cell lysates and the culture medium. Lipid peroxidation increased 2.5-fold when expression of the SeP protein was blocked with a SeP antisense vector. Also, HBx transfection increased lipid peroxidation by 3.0-fold, whereas the hepatitis B virus core protein (HBc) had no significant effects. The induction of lipid peroxidation due to the block in SeP protein expression or treatment with ferric chloride (FeCl3) up-regulated the expression levels of TNF-a mRNA and protein. The pattern of HBx-induced lipid peroxidation and TNF-a up-regulation was reversed by SeP introduction. These results suggest that HBx induces lipid peroxidation via down-regulation of SeP expression, resulting in increased expression of TNF-a in the human hepatoma cell line, HepG2.

Sputter deposition of magnetic material has to overcome challenges due to short circuiting the magnetics of the magnetron cathode. Hollow cathode processes in contrast require no magnets at all to enhance the ionization. Therefore, the high rate deposition of magnetic films becomes possible. The hollow cathode glow discharge can either be utilized for a sputter process where material is sputtered inside a hollow geometry and transported towards a substrate by an intense argon flow (Gas Flow Sputtering, GFS), or the substrate itself is inserted into the hollow cathode glow discharge (Inside Hollow Cathode Process, IHC). Results of both processes for the deposition of hard magnetic CoSm coatings will be discussed. In the case of GFS, the magnetic properties are influenced by independent parameters, especially ion bombardment and substrate temperature produced by external heating. In the case of IHC, substrate heating results from the intense glow discharge and thus the parameters temperature, growth rate and ion bombardment are dependent on the discharge power. Process conditions and the resulting process properties will be discussed. As one example, we applied hollow cathode processes to deposit thick rare-earth hard magnetic films for a precise angular positioning system on a commercial ball bearing.


Dual-Active-Bridge (DAB) converters, which have the advantages of high voltage transformation ratio, electrical isolation, easy to realize modular expansion, are widely used in various scenarios. And in order to realize high-power energy transmission with voltage and current stress reduced, multi-parallel structure converter has become a accepted solution. Focusing on two key indicators: dynamic response and sub-module power balance, we proposed a cooperative predictive control with power-balancing for input-series output-parallel (ISOP) DAB converters in this paper. Based on master-slave control, this strategy selects one DAB converter as the master module, controlling with constant voltage model predictive control (MPC) algorithm, and then takes its input voltage as the reference of other slave modules to achieve power balance. Finally, simulations are built to prove that the proposed strategy: (i) has excellent dynamic performance (ii) can achieve power balancing effectively


This paper presents a novel method of profiling the phase currents to minimize the torque ripple of a switched reluctance machine. The method is a combination of machine design and control algorithm. The minimization is accomplished in three steps: The first step is to design a machine that has symmetric torque characteristics with an extended flat portion, the second step is to find the required current profile through simulation, and the third step is the fine tuning of the profile. The simulation is done to verify the method through a coupling of the finite-element-based machine model and the Matlab/Simulink-based dynamic controller model. The coupled simulation considers the nonlinearities, electrical loss, magnetic loss, and mutual coupling. Experimental verification validated the torque-ripple minimization procedure.


Analysis of marital fertility in rural Derry c. 1911 confirms the presence even then of a gap between Catholics and Protestants. The difference was small, however, compared to today's, and for couples who had married before the mid-1880's it was insignificant. Various indicators of 'wealth' suggest that, all else equal, wealthier couples have more children, thereby suggesting that children are a 'normal good' in the economic sense. At given values of the 'wealth variables', labourers tend to have more children than farmers. Controlling for these economic factors tends to widen the fertility gap between Catholics and Protestants.


Since the advent of standard national accounts data over 60 years ago, economists have relied on monthly or quarterly data supplied by central statistical agencies for macroeconomics modelling and forecasting. However, technological advances of the past several years have resulted in new high-frequency data sources that could potentially provide more accurate and timely information on the current level of economic activity. In this paper we explore the usefulness of electronic transactions as real-time indicators of economics activity, using Canadian debit card data as an example. These data have the advantages of daily availability and teh high market penetration of debit cards. We find that (i) household transactions vary greatly according to the day of the week, peaking every Friday and falling every Sunday; (ii) debit card data can help lower consensus forecast errors for GDP growth; (iii) debit card transactions are correlated wtih Statistics Canada's revisions to GDP; (iv) high-frequency analyses of transactions around extreme events are possible, and in particular we are able to analyze expenditure patterns around the September 11 terrorist attacks and the August 2003 electrical blackout.


Self-assembled monolayers of free-base naphthalocyanine are examined in the context of analogous phthalocyanine films, revealing the influence of the more extended π-electron system on monolayer properties. Naphthalocyanine was vapor-deposited on a graphite substrate in ultrahigh vacuum and investigated in situ at low temperature (50 K) using scanning tunneling microscopy (STM). The crystallographic monolayer parameters of the deposited films were determined by means of submolecularly resolved STM images. In addition, vacancies in the monolayer have allowed for an accurate measurement of single molecule azimuthal angles. In STM topographs with submolecular resolution, a clear difference is evident between tunneling images corresponding to occupied and unoccupied sample states. The intramolecular structure exhibited by the STM images can be understood qualitatively by considering frontier orbitals calculated for isolated molecules. Moreover, single point tunneling spectra show a distinct signature of the o...

The practice of creating and developing general-education complexes, as innovative educational organizations, has brought about the need to look into the issue of continuity – both across a complex's structural units and different levels of general education. The problem is that most of today's research related to implementing continuity deals primarily with vertical continuity, while less attention is focused on issues related to horizontal continuity. In pedagogics, there currently lacks thorough research on issues related to the analysis of how well general-education complexes are implementing continuity across their education system, there being a want of proper criteria for evaluating the performance of general-education complexes with regard to implementing continuity and a lack of conceptual foundations and methods of analysis. The purpose of this paper

In India to this day, in Vaishnava temples, a veil is stretched before the image of Krishna which is located in the garbha, the dark womb of the structure. Only the faithful who sing praises to God for hours are there when the priest suddenly throws the veil aside, revealing the face of God, the Truth itself. A few moments later the priest again draws the veil across the image of the symbol of Divine Love.


Numerous advantages of contractual devices in the field of inheritance law, as well as the trends of development of the succession law, imposed the need to devote special attention to the impact of contract of inheritance on the principle of freedom of testation, as the reflexion of the principle of autonomy of will in the inheritance law. The comparison of various legal systems showed great divergences regarding contracts of inheritance: legal regulations varied from its wide acceptance (Germany, Switzerland), through its exceptional and partial permission (Austria), to its explicit ban (in numerous states, like Italy, Greece, Spain, Croatia, Slovenia). Since it cannot be renounced unilaterally, one of the main arguments for its prohibition is its incompatibility with the principle of freedom of testation. However, the principle of freedom of testation is a value respected and protected by all the legislators imposing the need of comparison of its content, scope and interpretation. The comparative analysis revealed possible solutions for indicated incompatibility between the contract of inheritance and the principle of freedom of testation. The author highlighted recent reforms of succession laws (in Italy and France) indicating a trend towards 'contractualisation' of succession law, encouraged by the legal scholars and the EU Commission. Introduced devices are variations of pacta de non succedendo. Review of their legal effects divulged that they, by definition, enhanced testator's testamentary freedom, giving testator and her/his heirs greater autonomy in succession planning. Finally, the author raised the question whether the actual interpretation of the principle of the freedom of testation (in the legal systems with the ban of the contract of inheritance) represented an excessive restriction of autonomy of will and therefore prevented adequate regulation of succession planning. The author gave comparative analysis and offered possible solutions that could be useful in future re- evaluation of the prohibition of the contracts of inheritance and its compatibility with the principle of freedom of testation.

Carabid beetles meet the requirements of many ecological studies because they are found in almost all terrestrial ecosystems, are responsive to environmental variables, and satisfy the criteria for useful bioindicators. Carabid biodiversity studies are now active nationally and internationally, but sampling regimes are rarely standardized and are often costly and time-consuming. We describe how a pitfall sampling protocol for carabids that is simple and easily repeatable by non-specialists can be used for the rapid assessment of site biodiversity quality baselines for the detection of change. Using this methodology, change in carabid beetle biodiversity quality is revealed, which would not be detected by simple registration of species richness or the presence of rare species.

In recent times, the popularity of Cognitive Radio has been increased because of its spectrum sensing characteristics. Using CR, the spectrum is utilized efficiently and maintain efficient communication when the primary user is not using the spectrum. In this paper, Bayesian detector is used for detecting the presence of primary user's signal. This approach is optimal when PU is not using the spectrum. The optimal Bayesian Detector with QAM modulation is deduced and analyzed in terms of probability of false alarm and detection over over AWGN channel. Simulation results show that the Bayesian Detector with 8-QAM modulation has optimum performance over Bayesian Detector with 8-PSK modulation.

Objective Little data are available on the prognostic significance of the matricellular protein tenascin-C (TN-C) in urinary bladder carcinoma (UBC). The aim of the present study was to evaluate TN-C in Egyptian UBC and to correlate it with available prognostic clinicopathologic features. Materials and methods TN-C immunohistochemical staining was performed for 15 normal urinary bladder biopsies and for radical cystectomies of 25 urothelial carcinoma (UC) cases, 21 squamous cell carcinoma (SCC) cases, and four adenocarcinoma (ADC) cases. Results TN-C expression was not observed in normal urothelium or stroma; however, of the total studied malignant cases, 59% showed TN-C expression in malignant cells and 66% in tumor stroma. TN-C expression was observed in malignant cells of all ADC cases, 76% of UC cases, and 29% of SCC cases. TN-C positivity in tumor cells was significantly associated with older age, larger tumor size, and advanced pathologic stage. SCC cases showed lower H-score values in malignant cells as compared with UC and ADC cases (P=0.000 and 0.016, respectively). TN-C expression in stroma cells was associated with a higher mitotic index in tumor cells. Conclusion TN-C is associated with progression of UBC and could be used as a tool for differentiation between UC and SCC in the difficult cases.


—In Carry Propagate Adders, carry propagation is the critical delay. The most efficient scheme is to generate C out 0 ( C in =0) and C out 1 ( C in =1) and multiplex the correct output according to C in . For any radix, the carry output is always 0/1. We present two versions of ternary adders with C in =(0V, V dd /2) and C in = (0V, V dd ) and two versions of quaternary adders with C in =(0V, V dd /3) and C in = (0V, V dd ). Using full swing V dd for C in reduces the propagation delays for ternary and quaternary adders. 6-bit, 4-trit and 3-quit CPAs are then compared.

The Characteristics of granulation of fine powders have been investigated by using a rotary-vessel-type mixer with rocking motion. The liquid as a binder is introduced into the mixer maintaining its inclination by means of ball bearings mounted on the inlet cover. A scraper and an impeller-type chopper are installed in the vessel to prevent the powder from sticking and to disintegrate the coarser agglomerates into the desired size range. The interior construction and operating conditions for granulation have been discussed based on the yield, size and size distributions of the granules. It is found that the granule formed by this mixer was relatively highly porous and soft.
