The pandemic accelerated some emerging drifts of change ongoing in the international system and, with it and in its wake, we moved from a VUCA to a BANI world. The COVID-19 has reshaped human mobility worldwide through the imposition of lockdowns, and also aggravated the vulnerability of some specific populations, such as the migrants. They became, in most regions of the world, even more vulnerable than they were before, especially those with an irregular status, refugees and asylum seekers. The purpose of this paper is to offer insights on the vulnerability of migrants in the context of COVID-19, focussing on the case of European countries.


Significance As DNA is replicated during cell division, it must be packaged by histones. To match the level of available histones to DNA replication, histone mRNA expression is controlled by a 3′-end stem-loop structure unique to replication-dependent histone mRNAs. In Drosophila, this regulation is mediated by histone mRNA stem-loop–binding protein (dSLBP), which has minimal tertiary structure when not bound to RNA. We show here that phosphorylation of dSLBP dramatically increases binding affinity for stem-loop RNA. The phosphorylated C-terminal tail of dSLBP does not contact RNA. Instead, increased negative charge on the C-terminal tail and stabilization of structural elements by a phosphorylation site within the RNA-binding domain promote more compact conformations that should reduce the entropic barrier to binding histone mRNA. Replication-dependent histone mRNAs end with a conserved stem loop that is recognized by stem-loop–binding protein (SLBP). The minimal RNA-processing domain of SLBP is phosphorylated at an internal threonine, and Drosophila SLBP (dSLBP) also is phosphorylated at four serines in its 18-aa C-terminal tail. We show that phosphorylation of dSLBP increases RNA-binding affinity dramatically, and we use structural and biophysical analyses of dSLBP and a crystal structure of human SLBP phosphorylated on the internal threonine to understand the striking improvement in RNA binding. Together these results suggest that, although the C-terminal tail of dSLBP does not contact the RNA, phosphorylation of the tail promotes SLBP conformations competent for RNA binding and thereby appears to reduce the entropic penalty for the association. Increased negative charge in this C-terminal tail balances positively charged residues, allowing a more compact ensemble of structures in the absence of RNA.


An image consists of large data and requires more space in the memory. The large data results in more transmission time from transmitter to receiver. The time consumption can be reduced by using data compression techniques. In this technique, it is possible to eliminate the redundant data contained in an image. The compressed image requires less memory space and less time to transmit in the form of information from transmitter to receiver. Artificial neural net- work with feed forward back propagation technique can be used for image compression. In this paper, the Bipolar Coding Technique is proposed and implemented for image compression and obtained the better results as compared to Principal Component Analysis (PCA) technique. However, the LM algorithm is also proposed and implemented which can acts as a powerful technique for image compression. It is observed that the Bipolar Coding and LM algorithm suits the best for image compression and processing applications.


Background There are limited data on the presentation of Takotsubo cardiomyopathy (TTC) in severe sepsis. Methods and Results This was a retrospective cohort study using the National Inpatient Sample database (2007–2013) of all adults with severe sepsis. TTC was identified in patients with severe sepsis using previously validated administrative codes. The primary outcome was in‐hospital mortality, and secondary outcomes included resource utilization and discharge disposition. Regression analysis was performed for the entire cohort and a propensity‐matched sample. An exploratory analysis was performed for predictors of TTC incidence and mortality in TTC. During this 7‐year period, in 7.1‐million hospitalizations for severe sepsis, TTC was diagnosed in 10 746 (0.15%) admissions. TTC was noted more commonly in whites, females, and among 65‐ to 79‐year‐old individuals. TTC was independently associated with lower in‐hospital mortality in severe sepsis (odds ratio, 0.58; 95% confidence interval, 0.51–0.65). This association was more prominent in females (odds ratio, 0.51; 95% confidence interval, 0.44–0.59]) compared with males (odds ratio, 0.69; 95% confidence interval, 0.55–0.85]). Presentation in later years of the study period, middle‐age, female sex, and white race were independent predictors for the diagnosis of TTC. Age ≥80 years, black race, greater comorbidity, and multiorgan dysfunction were independently associated with higher in‐hospital mortality among TTC admissions. Conclusions TTC is observed with increasing frequency in severe sepsis and was associated with a significantly lower in‐hospital mortality compared with patients without TTC. Presentation in later years of the study period, middle age, female sex, and white race were independent predictors for the diagnosis of TTC in severe sepsis.

Prior choice for Bayesian model comparison can be problematic for several reasons. In particular, for the comparison of two nested models, it was recently pointed out that typical prior choices may produce an unsatisfactory learning behavior of the Bayes factor. More in detail, if the sub-model is not true the accumulation of evidence is exponentially fast in favor of the encompassing model, whereas it is only sub-linear in favor of the sub-model under the assumption that the latter is true. To alleviate this imbalance, it was suggested that the prior under the encompassing model be modified so that it vanishes over the sub-space corresponding to the sub-model, thus obtaining a Non Local Alternative Prior (NLAP). In this work, we develop NLAPs for the comparison of Gaussian directed acyclic graphical models, and contrast their performance with that of traditional priors.


The field experiment comprising 12 advance lines of okra was carried out to assess thermal requirement for flowering and total fruit yield during rainy seasons at CCS Haryana Agricultural University, Hisar. The results revealed that okra crop required 762.4 dayoC accumulated heat units for flowering and 1600.5 dayoC accumulated heat units for total fruit yield production. Advance line HRB 108-2 required minimum for flowering (664.4 dayoC) and highest 1644.8 dayoC for total fruit production with better thermal use efficiency (9.1 kg ha-1 ºD) indicating its suitability for early and more fruits availability for longer period. Fruit yield production showed significant positive association with heat unit requirement in all the years. The R2 values of regression equation could explain the variation  between 63-87% of the total variation in fruit production in okra.


According to the ecological footprint theory,a comparative study was maked on the differences of ecological footprint to China's regional.The results showed that:①the country's per capita ecological footprint is 1.22 in 2006.From east to west,it showed a clear trend of diminishing.The values of the eastern provinces and autonomous regions with economically developed,to the ecological footprint of biological resources,is significant higher than the central and western regions with relatively backward of economy;the contribution is significantly to the footprint of energy consumption in the energy-rich provinces and autonomous regions for the ecological footprint of energy.②In the eastern region,the absolute value of the ecological footprint is relatively high and the contribution rate which comes from ecological footprint of biological resources is generally higher than the ecological footprint of energy to per capita ecological footprint;in the central and western regions,the contribution rate which comes from bio-ecological footprint is well-matched with the ecological footprint of energy on the ecological footprint per capita ecological footprint,but the absolute value of the ecological footprint of biological resources,energy consumption,as well as ecological footprint per capita ecological footprint is relatively low in the central and western regions,which match with the living standards in line with the pattern in modern times.③At the same time,the deficit of ecological of china is more serious in 2006 which is 0.7.The ecological carrying capacity of the central and western regions is significantly higher than the eastern provinces and autonomous regions which increases from east to west.④The level of sustainable development among regions is that:eastern region central regionwestern region.

Objective To investigate the preventive and therapeutic effects of ulinastatin (UTI) on myocardial damage following early burn injury. Methods A total of 72 SD rats were randomly divided into simple burn group (B group) and UTI-treated group (U group) and were subjected to 30% total body surface area Ⅲ scald injury. Plasma cTnI and CK-MB concentrations were measured by enzyme linked immunosorbent assay and histologic changes in myocardium were examined before and at 1, 3, 6, 12 and 24 h after burn. Results Serum cTnI and CK-MB levels at 3, 6, 12, 24 h after burn injury were significantly higher than before burn (P0.01). Serum cTnI and CK-MB levels in U group were lower than in B group (P0.01, P0.05). At 3 h after burn, fiber engorgement, transverse striation derangement, cell boundary unsharpness, cytoplasm destruction, intercellular substance edema were observed. The pathomorphological changes were aggravated at 6 and 12 h after burn injury, and dissolvation, degeneration and necrosis occurred, which were mild as compared with that in B group. Conclusion Severe myocardial damage occurred following early burn injury. Ulinastatin could alleviate myocardial damage.


Abstract Eagle's syndrome, an uncommon sequela of an elongated styloid process, can manifest itself as a sensation of a foreign body in the throat and a retrogoniac or anterolateral neck pain often referred to the TMJ and the ear. When treating patients affected by temporomandibular disorders (TMD), complaining of atypical orofacial pain, and with a concomitant radiographic finding of a bilaterally elongated styloid, the possible coexistence of Eagle's syndrome should always be considered. The aim of this review is to present an overview of the epidemiology, pathophysiology, diagnosis, and therapy for Eagle's syndrome and to help the clinician in differential diagnosis with other conditions that can provide similar signs and symptoms.


Following a dividend distribution, investors expect the stock price to decrease on the ex-dividend day. With no market imperfections, the price decrease should exactly match the amount of the dividend, thus eliminating all opportunities for profitable arbitrage. Allowing for different taxes on dividends and on capital gains results in a stock price adjustment ratio different from one, but there is still a unique equilibrium. With a simple model, considering four types of investors, we show that the consideration of transaction costs results in multiple possible equilibria (equilibrium zone), defined by the arbitrage boundaries of each type of investors. We also show that trading activity by the different types of investors is reflected in abnormal trading volume.


The evapotranspiration was estimated using 11 temperature-based models and was compared with the FAO Penman-Monteith model. The results showed that the modified Hargreaves-Samani models estimate the evapotranspiration better than the other models in the most provinces of Iran. However, the values of R2 were less than 0.98 for 15 provinces of Iran. Therefore, the models were calibrated and precision of estimation was increased (the values of R2 were less than 1.00 (with respect to two decimal numbers) for only five provinces in the modified models). The temperature-based models estimated the evapotranspiration in the north east and south west provinces of Iran better than other provinces. The best precise methods were the modified Hargreaves-Samani 1 method for AL (before calibration) and the Hargreaves-Samani method for AR, the Modified Hargreaves-Samani 2 method for SE and GH, the modified Hargreaves-Samani 1 for FA, and the modified Hargreaves-Samani 3 for MZ (after calibration).


Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951–2015) and spring (1951–2000) seasons. Firstly, a preliminary subdivision of rainfall grid points into zones was applied depending on spatial homogeneity and seasonality of rainfall. This introduced new clusters, including nine zones for summer rainfall peak (July/August) and five zones for spring rainfall peak (April/May). Afterward, the time series for each zone was derived by calculating the rainfall averaged over grid points within the zone. Secondly, the oceanic regions that significantly correlated with the Ethiopian rainfall were identified through cross-correlations between rainfalls averaged over every homogeneous zone and the monthly averaged SST. For summer rainfall as a main rainy season, the results indicated that the Gulf of Guinea and southern Pacific Ocean had a significant influence on rainfall zones at a lag time of 5–6 and 6–7 months. Besides, for summer rainfall zones 8 and 9 at lag time 5–6 months, the common SST regions of the southern Pacific Ocean showed the opposite sense of positive and negative correlations. Thus, the difference in SSTs between the two regions was more strongly correlated (r ≥ 0.46) with summer rainfall in both zones than others. For the spring season, the results indicated that SST of the northern Atlantic Ocean had a strong influence on spring rainfall zones (3 and 5) at a lag time 6–7 months, as indicated by a significant correlation (r ≥ −0.40). Therefore, this study suggests that SSTs of southern Pacific and northern Atlantic oceans can be used as effective inputs for prediction models of Ethiopian summer and spring rainfalls, respectively.

Consider the constrained part (denoted as the plant) of a control system, consisting of n cascaded sections, each of whose outputs can be sensed for feedback purposes. Feedback from these points is to be used to achieve a priori specified tolerances on the system response, despite great uncertainty in plant parameter values. In this first quantitative work of its kind, the feedback is permitted to proceed directly to internal plant variables, constituting ' plant modification '. The reason is that the internal plant signal levels needed to achieve a specific output are now affected by the feedback loops. This is in contrast to previous quantitative research in which the feedback was confined to the plant input. The plant signal levels needed to achieve a specific output were then not influenced by the feedback. Plant modification feedback permits greater reduction in the ' cost of feedback ', in terms of feedback loop bandwidths and effect of sensor noise, at the cost of increase in plant internal signal ...


Ultrathin LiTaO3 wafer is needed as a sensitive lay for fabricating high performance pyroelectric infrared sensor array.Since the thickness of LiTaO3 wafer was thicker than the required thickness,the LiTaO3 wafer was processed by the novel wafer bonding and mechanical thinning processes,i.e.benzocyclobutene(BCB) bonding,grinding,polishing,heating stripping and BCB etching.The ultrathin single crystal LiTaO3 wafer with dimensions of 10 mm×10 mm×25 μm was prepared with the thinning processes.The pyroelectric coefficient of the thinned LiTaO3 wafer is 1.6×10-4 Cm-2K-1.The measured results of the thinned LiTaO3 wafer show that the thickness uniformity,surface roughness and surface profile accuracy can meet the requirement of the application.


A new state of the art double gate junctionless transistor (DGJLT) namely the rectangular core–shell DGJLT (RCS-DGJLT) based common source amplifier circuit is designed to investigate the performance. An RCS-DGJLT device is designed using a visual technology computer aided design tool and look up table-based Verilog-A model has been designed to carry out spice simulation of the circuit. Device simulation of RCS-DGJLT shows the extraordinary performance when compared to conventional DGJLT. The RCS-DGJLT exhibits an OFF current (Ioff ) ∼10−14 A, ON current (Ion ) ∼10−5 A, ON/OFF current ratio (Ion /Ioff ) ∼109, subthreshold slope ∼68.9 mV decade−1 and drain induced barrier lowering ∼52.6 mV V−1. Also, the AC response of RCS-DGJLT exhibits good performance like lower miller capacitances of order 10–16 F, maximum unity gain frequency of 138.8 GHz, transconductance generation efficiency of 40 V−1, and gain-bandwidth product of 25.4 GHz. The common source amplifier circuit using RCS-DGJLT provides the amplification up to 3.3 times which implies gain (Av ) to be 3.3. The low leakage power of 10.4 pW and average power of 31.2 µW of common source amplifier circuit based on RCS-DGJLT shows the greater potential of using the proposed device in analog applications. Also, the complete flow chart of the process used to design an analog circuit based on proposed RCS-DGJLT is discussed. The result shows the potential of using the RCS-DGJLT device in designing high-frequency applications.


A modification of the Southwell plot is developed to predict lateral buckling loads of beams. The analysis is carried out both for a beam under uniform moment and for a beam loaded by a concentrated force at the center of the span. The method is applied to one set of test results from the literature, and good agreement is obtained.


Although the maximum collector-emitter voltage of a high-voltage insulated-gate bipolar transistor (HV-IGBT) reaches 3300 V or higher, it still cannot satisfy the requirements of some high-voltage high-power converters. Applying power semiconductor devices in series connection can effectively improve the voltage rating and power rating of a power electronic converter. The key issue of device series connection is voltage balancing in static switching state and dynamic switching state. In this paper, a three-level converter based on series-connected HV-IGBTs is presented, its voltage-balancing subcircuits are analyzed, and the parameter design method for the converter is proposed. During the design process, key performance indexes of the series connection circuit, such as the voltage-balancing effect, loss of the voltage-balancing circuit, switching loss, and switching time, are comprehensively considered. Moreover, component parameters of the three-level converter are calculated considering the influence of the voltage-balancing circuit. The proposed parameter design method is applied in the development of a three-level HV-IGBT (4500 V/600 A) series connection test platform with 10 000-V rated dc-link voltage. Experimental results verify the validity of the proposed method.


THE PRESENT INVESTIGATION WAS CONDUCTED to determine, a) the normal values for urinary acid phosphatase in men, women and children; h) the site of origin of urinary phosphatase; and c) the influence of altered physiological states on urinary phosphatase excretion. That the urine of humans contains an enzyme capable of splitting organic phosphates has been demonstrated by Demuth (1) and others (2, 3, 4). These authors agree that optimal phosphate splitting in urine occurs in an acid medium close to a pH of 5. Kutscher (4) found an alkaline phosphatase present at plasma level in the urine. Considerable controversy exists, however, as to the site of formation of urinary phosphatase, its levels of excretion and sex differences in excretion levels. WaldschmidtLeitz and Nonnenbruch (2) found a phosphatase present in urine with an optimum pH range of 5 to 6 and in concentrations much stronger than in serum. They believed

According to n(LiV3O8)∶n[LiNiO2(or LiMn2O4)]=12∶1,Ni or Mn doped LiV3O8 was prepared by sol-gel method,the samples were analyzed by XRD,cyclic voltammetry and galvanostatic charge-discharge tests.Doping had no effect to the crystal structure of the sample.When cycled at 0.1 C in 1.8~3.8 V,the initial specific discharge capacity of the sample doped Mn was 387.9 mAh/g,which was 29.3% higher than the sample without doping(299.9 mAh/g),the specific discharge capacity at the 25th cycle was 368.9 mAh/g,the charge-discharge efficiency was always above 97.4%.Although the initial specific discharge capacity was increased,the cycle performance of Ni doped sample was poor.


Before the 200-year span of what most Americans regard as their national story, were three centuries of turmoil following the forced entry of the Americas into the political sphere of Late Medieval Europe. Another 11,000 years of human history preceded the volatile half-millennium of postcontact history in the Americas. Historians have largely left both periods to archaeologists, who hid the social histories of each behind the prefixes "pre" and "proto." By defining history as the period for which written European texts are available, much of the story of North America has been consigned to the murky neverland of prehistory, not to say nonhistory. Colin Calloway brings this world into clear focus through his exacting synthesis of archaeology, documentary material, and oral tradition. One Vast Winter Count is a monumental work of prenineteenth century American history. In eight thematic chapters, the book weaves together an astonishing amount of scholarship and primary data to paint a complex portrait of American Indian history. This book corrects oversimplified views of preand postcontact Indian life, brings Indians under the tent of historical research, and fills in many gaps left by conventional history textbooks. The story begins with the earliest known cultures in the American West. This opening section explains that the West was and is a series of Indian homelands in which social, political, economic, and environmental factors have contributed to complex social histories and dynamic population interactions. Calloway skillfully distills a vast body of archaeological reports and oral tradition, devoting separate chapters to the influence of hunting, postglacial environmental changes, and the development of maize horticulture. From the minutiae of data, he shapes a well-rounded description of precontact life in North America, including religion and mythology, as well as material culture. This section serves to remind archaeologists of the larger picture to which their discoveries contribute. For nonspecialists, Calloway puts cultural developments in North America in the context of similar developments worldwide. Specialists may question some of the conclusions, for example regarding differences in hunter-gatherer versus horticulturalist religions, but more as a matter of discussion than dismissal. The remaining portions of the book, concerning the postcontactperiod to about AD 1800, are a masterpiece of synthesis. Here Calloway builds his well-reasoned argument for viewing conflict and change in native North America as part of larger world events. From the Medieval concept of the Christian warrior culture that motivated the early Spanish conquistadors who no longer had Muslim "infidels" to set to rights to fallout from the European hunger for new trade venues in the postMedieval world, IndianAmerica was violently swept into European affairs. As noted, "imperial contests played out at the village level" in the Americas. In this complex story, Indians are neither naive children of nature nor helpless before technologically superior European invaders; they are active participants in the events of the period, as savvy and selfmotivated as the colonizing forces. Indians are portrayed as both victim and victimizer. In this narrative, Indians sometimes openly resist European hegemony and often exploit conflicts between French, Spanish, and English colonists to their own advantage, playing one superpower off against another. Indian people appear here as rebels, strategists, negotiators, freedom fighters, mercenaries, conquerors, traders, producers, traditionalists, innovators, environmental engineers, slaves, and slavers.

Extremely large-scale massive multiple-input multiple-output has shown considerable potential in future mobile communications. However, the use of extremely large aperture arrays will lead to near-field and spatial non-stationary channel conditions, which result in changes in transceiver design and channel state information acquisition. This letter focuses on the channel estimation problem and describes the non-stationary channel through a mapping between subarrays and scatterers. We propose subarray-wise and scatterer-wise channel estimation methods to estimate the near-field non-stationary channel from the views of the subarray and the scatterer, respectively. Numerical results demonstrate that the subarray-wise method can derive accurate channel estimation results with low complexity, whereas the scatterer-wise method can accurately position the scatterers and identify almost all the mappings between subarrays and scatterers.


Objective InvestigatetheclinicaleffectofXuezhikangcombinedwithatorvastatininthetreatmentofel- derly patients with hypertension complicated with coronary heart disease. Methods Eighty patients with hypertension com- plicated with coronary heart disease in our hospital from January to June in 2012 were enrolled in the study. According to the random principle, patients were divided into atorvastatin group(40 cases) and Xuezhikang combined with atorvastatin group(40 cases), with 8 weeks as a treatment course. The patients of the atorvastatin group received oral atorvastatin calcium(20 mg once daily), while those in Xuezhikang combined with atorvastatin group received Xuezhikang(2 pieces twice daily) on the basis of the atorvastatin group. All patients avoid taking other drugs affecting blood pressure and coronary heart disease and in the two weeks before treatment and during treatment. Diastolic blood pressure(DBP), systolic blood pressure(SBP), blood lip- id parameters including total cholesterol(TC), triglyceride(TG), high density lipoprotein(HDL-C) and low density lipopro- tein(LDL-C) and other indicators were compared between the two groups. Results The total effective rate in Xuezhikang combined with atorvastatin group(70.00%) was significantly higher than that in atorvastatin group(55.00%), with statistically significnat difference between the two groups(χ2=11.70, P0.05). After treatment, the levels of the indicators detected in Xue- zhikang combined with atorvastatin group were all significantly better than those in atorvastatin group(P0.05), except for HDL-C. Conclusion Xuezhikang combined with atorvastatin has significant clinical effect in the treatment of elderly pa- tients wit hypertension complicated with coronary heart disease, which is worthy of clinical application.


A B S T R A C T Cultures of dividing skin fibroblasts from normal and sclerodermatous human skin have permitted estimations of soluble collagen concentration, net collagen accumulation, cell-doubling times, and the com-parison of morphologic and ultrastructural characteristics. In vitro, the scleroderma fibroblast produces more soluble collagen, synthesizes collagen more rapidly, and fourfold more of its protein synthetic activity is directed to collagen production than in the normal skin fibroblast. Cell-doubling times and morphologic and ultrastructural observations of cells in culture have not provided clues to the nature of the biologic defect in the regulation or activation of collagen synthesis by the scleroderma fibroblast. (3). The present report provides further data demonstrating: (a) increased soluble collagen in dividing scleroderma skin fibroblast cultures; (b) increased incorporation of ['4C]proline into collagen hydroxyproline by scleroderma fibroblasts; (c) similar patterns of cell growth, turnover, and morphology of scleroderma and normal skin fibroblasts; and (d) the persistence of an increased capacity to synthesize collagen by scleroderma fibroblasts after up to 15 subcultures. These suggest basic in the of at the mal and scleroderma skin was confirmed by histologic examination in all cases. The data of the present report was obtained fromn cell lines developed from eight skin biopsies of five scleroderma patients and eight control biopsies of eight subjects with no apparent skin disease. All cell lines, skin biopsies, and subjects were different from those of the previous re- port because of a freezer failure which destroyed the earlier cell lines. All patients with scleroderma had progressive cutaneous involvement of 6-12 mo duration.


The hot working behaviour of two austenitic stainless steels: SS304 and Ti-modified 15Cr-15Ni-2Mo (Alloy D9) were studied by hot compression test at temperatures of 900-1200°C and at strain rates of 0.002- 1 s -1 . The progress of dynamic recrystallization (DRX) was modelled by the Avarmi kinetics equation. The flo w softening was directly related to the DRX vo lu me fract ion and the DRX time was determined by strain rate. For quantification of recrystallizat ion rate, the time corresponding to the DRX fraction of 50% was used. Analysis of the sigmoid-shaped recrystallization curves revealed that the rate of DRX increases with increasing deformation temperature and strain rate. Avrami exponents obtained indicated heterogeneous grain or twin boundary nucleation during DRX of these steels. Results of the Avrami analysis were used to predict the DRX flow curves for d ifferent deformation conditions.


Diagnosing the condition of a machine by its vibration signature has a great deal of appeal. The problems that have been encountered in its widespread use involve the availability of analysis equipment and the skill of the data analyst. Combining a real time analyzer with a computer can process a great amount of data quickly and reduce the drudgery of analysis. Single‐frequency Fourier component calculation may easily be made in the computer and can take the place of tracking filters and phase meters. This ability to process, store, and recall data quickly, coupled with the ability to program a computer to recognize basic problem symptoms, is making automated signature analysis for machine diagnostics possible, Hardware and software examples demonstrating this capability are presented to support the conclusions.


We studied the effect of the different dopants in the manganese-zinc ferrites on the low power loss by measuring the magnetic properties and observing the grain boundary structures in this paper. The results was compared to the result of CaO-SiO_2 used commonly. We have found that Ta_2O_5-Nb_2O_5-CaCO_3 as an association obtained better quality at optimum processing conditions.


There are two main problems when performing Opinion Mining (OM) with data streams: the lack of labeled data and the need to update the learning model. The most used OM techniques cannot deal well with these challenges, so, an alternative is to use semi-supervised methods, such as the Active Learning, which is a method to label only selected data rather than the entire data set; however, it requires the choice of a sampling strategy to select the data to be labeled. In this paper, we evaluated eight strategies in ten data sets, in order to identify the best ones for OM with Twitter streams. According to our experiments, the Entropy strategy showed the best results, but it selects a large number of instances to be labeled, requiring further investigation.


ABOUT THE INTERNATIONAL NEUROETHICS SOCIETY The International Neuroethics Society (INS) recently commented on the ethical considerations of neuroscience research and the application of neuroscience research findings for the Presidential Commission for the Study of Bioethical Issues, published in the Federal Register Jan. 31, 2014.

INTERACTION EFFECTS BETWEEN ETHNIC IDENTITY AND ACADEMIC ACHIEVEMENT AMONG ADOLESCENT ETHNIC MINORITIES EDISON SANTANA, B.A. UNIVERSITY OF MASSACHUSETTS M.ED., UNIVERSITY OF MASSACHUSETTS AMHERST PH.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Ronald Fredrickson, Ph.D. This study assessed the degree to which ethnic identity, ethnic identity achievement, self perceived differences in skin color, self-esteem, gender and social class were associated with academic achievement (CPA) among Asian (105), Latino (40), Caucasian (204), Afro-American (40), and Native American (10) adolescents. The subjects, students from an independent residential high school in the Northeast, consisted of both genders, grades 9 through 13 from a range of socioeconomic statuses (N=408) . Each student was handed a packet to complete and signed the consent form. Each subject was then instructed to choose the closest skin color from a skin color chart specifically developed for this study. Interviews were completed after each student's skin color was also rated by three independent raters. Subjects completed the skin color chart developed by the examiner for this study, the Rosenberg (global) Self-esteem Scale, the Multigroup Ethnic Identity Measure, and the Hollingshead Two Factor Index of Social Position. Academic performance measures (CPA) and academic aptitude vi scores (V & MSAT) were obtained from school files, reflecting the yearly average performance. Correlation's between ethnic identity and ethnic identity achievement revealed a significant negative correlation with GPA, VSAT and MSAT for the entire group but dissimilar results for the specific ethnic groups. In addition , correlations between gender , skin color , grade level , SES and GPA by ethnic group revealed significant findings for some but not all ethnic groups. In addition, multiple regression analysis results revealed, when SES was controlled , that Skin Color , Gender and Ethnic Identity Achievement (EIA) , in order of strength, had a positive correlation with GPA, explaining 12% of the variance for the African American, Latino and Native American subgroups ( in order of degree) . On the other hand, multiple regression results revealed no difference in GPA scores for the Asian subgroup, whereas a negative trend was revealed for the


In this paper, we propose new full diversity unitary space-time codes based on Hamiltonian constellation designs. Our proposed constellations can be used for any number of antennas and for any data rate. For two transmitter antennas, the constellations are constructed from cyclic group codes. For a larger number of transmitter antennas, the design employs the direct sum of 2 times 2 Hamiltonian matrices and roots of unity. We give some examples of proposed constellations, and also show that they outperform known design techniques in the literature


Abstract This study investigated the structural validity and construct comparability, across boys and girls, of a newly developed measure of work values. The total sample was split into two equal parts, and based on an item-level factor analysis of the first sub-sample, fit statistics provided support for a six-factor first-order structural model with the following constructs: Power, Money, Tidy environment, Teamwork, Work–Family Balance and Ability Utilization. This structure was confirmed in the second sub-sample, and strict measurement invariance for the measurement model was obtained in this sample. Additionally, the factor variances/covariances were invariant. Five non-invariant latent means were found, with girls scoring higher on the Balance and Personal Challenge values, and boys scoring higher on the Power, Money and Teamwork values.


A non-LTE abundance determination of magnesium, iron, and barium was carried out for the atmosphere of Vega. The results indicate marked underabundances of these elements relative to the solar values. First preliminary results of numerical simulations of convective and oscillatory phenomena in the atmosphere of Vega are briefly described.


Motivated by recent results of Kapron and Steinberg (LICS 2018) we introduce new forms of iteration on length in the setting of applied lambda-calculi for higher-type poly-time computability. In particular, in a type-two setting, we consider functionals which capture iteration on input length which bound interaction with the type-one input parameter, by restricting to a constant either the number of times the function parameter may return a value of increasing size, or the number of times the function parameter may be applied to an argument of increasing size. We prove that for any constant bound, the iterators obtained are equivalent, with respect to lambda-definability over type-one poly-time functions, to the recursor of Cook and Urquhart which captures Cobham's notion of limited recursion on notation in this setting.


The practical usage of ionics of a hard material in new units and devices production are described in this article.


BACKGROUND
To further evolve in an evidence-based fashion, medical education needs to develop and evaluate new practices for teaching, learning, and assessment. However, educators face barriers in designing, conducting, and publishing education research.

OBJECTIVE
To explore the barriers medical educators face in formulating, conducting, and publishing high-quality medical education research, and to identify strategies for overcoming them.

METHODS
A consensus workshop was held November 5, 2013, at the Association of American Medical Colleges annual meeting. A working group of education research experts and educators completed a preconference literature review focusing on barriers to education research. During the workshop, consensus-based and small group techniques were used to refine the broad themes into content categories. Attendees then ranked the most important barriers and strategies for overcoming them with the highest potential impact.

RESULTS
Barriers participants faced in conducting quality education research included lack of (1) expertise, (2) time, (3) funding, (4) mentorship, and (5) reward. The strategy considered most effective in overcoming these barriers involved building communities of education researchers for collaboration and networking, and advocating for education researchers' interests. Other suggestions included trying to secure increased funding opportunities, developing mentoring programs, and encouraging mechanisms to ensure protected time.

CONCLUSIONS
Barriers to education research productivity clearly exist. Many appear to result from feelings of isolation that may be overcome with systemic efforts to develop and enable communities of practice across institutions. Finally, the theme of "reward" is novel and complex and may have implications for education research productivity.


The Islamic gardens originated from the direct imitation of the early agriculture in Arab.They have been famous for their unique qualities and characteristics,and have long been a symbol of gardens in paradise in people's minds.Surrounded by high walls or buildings,the Islamic gardens are the most restrained and the quietest gardens in the history all over the world.With the typical cross-shaped pattern,the Islamic gardens are usually divided into four parts by cross-shaped drains or roads,the drains at the intersection are the centers of the gardens where there are always fountains or bowers,tall shade trees,flower beds and the trim hedgerow plants constitute unique landscape characteristics.


TPS624 Background: According to advanced neoadjuvant chemotherapy (NACT), which dual HER2 blockage in HER2+ BC and adding carboplatin or immunotherapy in triple-negative breast cancer (TNBC) increased pathologic complete response (ypCR) rates up to 68% and 80%. Because ypCR patients showed better survival, the indications for NACT have expanded to early BC and the expected ypCR rate has increased. Therefore, it may be reasonable to consider omitting surgery in cases with excellent responses to NACT. Several recent retrospective studies and pilot prospective studies have reported axillary pathologic complete response (ApCR) is highly correlated with breast pathologic complete response (BpCR) in HER2+ or TNBC after NACT. The current report describes the design of omission of sentinel lymph node biopsy (SLNB) after NACT in HER2+ or TNBC patients with excellent response. Similarly, EUBREAST-01 (NCT04101851) study is ongoing omission of sentinel lymph node biopsy (SLNB) after NACT in HER2+/TNBC with radiologic complete remission and a BpCR. Methods: The ASLAN trial is a prospective, multicenter, single-arm, clinical study. Five tertiary care hospitals in South Korea are participating. Inclusion criteria: women aged 20-69; cT1-3N0-1M0; HER2+ or TNBC (defined by ER-negative (< 10% positive cells in IHC) and PgR-negative (< 10% positive cells in IHC)); expected complete remission at physical examination and radiological expected Tumor size ≤ 2cm or non-mass enhancement ≤ 4cm at breast MRI after standard NACT; planned breast conserving surgery (BCS) with whole-breast irradiation; ECOG performance status 0-1. Exclusion criteria: SLNB before NACT; previous axillary surgery; bilateral BC. Patients who are eligible proceed BCS. After BCS, patients who showed BpCR are enrolled with omission of SLNB. Patients with no BpCR proceed with routine axillary surgery. The assumption for acceptable 5-year RFS ≥84% is based on previous study findings. The calculated total case number for per- protocol analysis is N=178. Primary endpoint: 5-year recurrence free survival. Secondary endpoint: local recurrence free survival, breast cancer specific survival, overall survival, ipsilateral axillary recurrence interval, distant metastasis free survival, contralateral breast free survival, re-operation rate according to breast biopsy after NACT, adverse event, and quality of life. The first patient was enrolled on September 2021. Among 147 patients who screened, 106 patients have been enrolled in January 2022. We plan to complete the target accrual by December 2025. Clinical trial information: NCT04993625 .

In this work, we explore the possibility of making predictions of solubilities from free-energy calculations by utilizing the relationship between solubility, free energy of solvation, and solute vapor pressure. Because this relationship is only strictly valid when all activity and fugacity coefficients are unity, it is not clear when it will hold and when it will break down for a given solute–solvent system. So we have tested the validity of this relationship using a variety of liquid solutes and solid solutes in liquid water solvent. In particular, we used a test set of 75 liquid solutes and 15 solid solutes composed of H, C, N, O, F, and Cl. First we compared aqueous free energies of solvation calculated from experimental solute vapor pressures and aqueous solubilities to experimental aqueous free energies of solvation for the 90 solutes in the test set and obtained a mean-unsigned error (MUE) of 0.26 kcal/mol. Second, we compared aqueous solubilities calculated from experimental solute vapor pressures...


Acute appendicitis is a common abdominal pathology presenting to the emergency department. An accurate diagnosis in the early stage is often difficult and the incidence of misdiagnosis, due other pathologies causing similar clinical signs, is very high. We present a rare case of congenital band mimicking acute appendicitis.


Recently, the micro-blasting process has been widely used to process brittle material, and a conventional circular nozzle has been commonly used. But the cutting performance of a circular nozzle does not process a large area well, so the use of a slot nozzle is considered. In this study, in order to improve the cutting performance of the micro-blasting nozzle, a new slot nozzle with a large aspect ratio is proposed and the flow characteristics and cutting performance are examined precisely by experimental and numerical analyses. The main results show that (1) setting the circular vane in the slot nozzle perpendicular to the stream can diffuse particle flow uniformly at the nozzle exit, making the particle velocity distribution uniform, (2) expanding the nozzle outlet at an angle, uniform air and particle velocity distributions at the nozzle exit can be obtained, (3) in spite of setting obstacles at the nozzle, a fine cutting efficiency is obtained compared to the conventional micro-blasting circular nozzle.


United States in particular, taking advantage of the Russo-Chinese Schism&dquo; (p. 294). And still more: &dquo;Therefore, any move toward normalization of relations between the United States and the Socialist [?] Republic of China should be aimed at a moderation of Soviet policies, trying to lead it toward a compromise-as in Berlin--persuading it to reassess its intransigence while it is being challenged on two fronts&dquo; (ibid.). All these are in order, and we can even take them in our stride. But the real disappointment in Ambroz's book lies in the fact that an important development in contemporary world politics, like the Soviet-Chinese schism, deserves to be studied cogently and without preconceived notions. The author, being a &dquo;veteran


This study is to analyze the performance and emission of the different proportionate of the diesel with cooking oil using as the blent, Which is used to measure the performance of the bio diesel. The fossil fuel usage is increasing due to the population growth and the need is also more, so we planned to make the biodiesel as a fuel with more efficient. Many literature has been studied with various consideration of the different concepts. The aim is to know about the emission and combustion of engine with the cooked oil which is the replacement of other type of fuel. When the cooked oil is mixed with diesel, a better performance has been occurred. The exhaust gases contain less pollutant. As a result environmental pollution has been minimized in the atmosphere. The good combustion will attain without the damage of engine and its parts.


The need to eliminate the backward traveling wave in HARP (harmonic auto-resonant peniotron) interactions is demonstrated. The theory and design of a ring-type resonant cavity to achieve this are described. It is shown that this cavity can support high-efficiency HARP interactions.<<ETX>>


The Corona virus, known as COVID-19, is different from previous viruses such as SARS, which has a very rapid spread. The form of its spread is also very easy, namely contact with objects exposed to the virus such as holding it and then accidentally hand touch the mouth, nose, and eyes then the virus will infect a person, or through breathing droplets produced by people infected with the virus that are spread with sneezing or coughing. Nutmeg spreading like this can only be limited by social distanching. The policy of distance protection has an impact on the prohibition of the implementation of worship involving worshipers such as Friday prayers, tarawih, praying five time in congregation, and 'Idaini. Rukhshah becomes an offer to this problem by giving lightness to the red and orange zones leaving the implementation of worship in congregation and carrying out worship at home, the yellow zone giving leeway to carry out worship in congregation at a minimum distance of one meter between worshipers by observing the appeals The government avoids contacting and washing hands, the green zone can carry out regular worship in congregation but heed the government rules of distance and washing hands (keep clean)


To unravel the "extra-atom" complexity of the title reaction, we exploit an experimental approach which, by taking advantage of the correlated information of coincident product pairs, allows us to peel off judiciously the intrinsic complications of a six-atom reaction, extracting the underlying backbone of three-atom dynamics. Examining the collisional energy dependencies of the pair-correlated attributes for a given state(s) of CD3 products from the title reaction, several of major observations can qualitatively be understood, whereas others await further theoretical investigations. An intriguing possibility for the existence of reactive resonances in this six-atom reaction is surmised.


Abstract We present a technique for the derivation of the density and its moments in the case of the discrete random variable that expresses the "waiting time" for an n-tuplet (especially in HH, HT, HHH) when a fair coin is flipped. In addition, we present some paradoxical situations that arise from them. These results are very useful in the field of mathematical games, in the history of probability, and in teaching.


Locadiff, an innovative imaging technique based on diffuse waves, has recently been developed in order to image mechanical changes in heterogeneous geological or man-made materials. This manuscript reports the on-site application of Locadiff to locate several pre-existing cracks on an aeronautical wind tunnel made of pre-stressed concrete. Using 32 transducers working at ultrasonic frequencies (80-220 kHz) where multiple scattering occurs, we monitor during 15 minutes an area of 2.5 m × 2.5 m of a 35 cm thick wall. With the wind tunnel in its routine operation, structural changes around the cracks are detected thanks to their closing or opening due to slight pressure changes. By mapping the density of such microstructure changes in the bulk of the material, the locating of three pre-existing cracks is properly performed in 3D.


A case of an adolescent boy with persistent thoracic symptoms and recurrence of pectus excavatum (after previous treatment with the Nuss procedure) is presented. During thoracoscopic revision, subdiaphragmatic migration of the implant was noted. The bar was removed without damage to the intra-abdominal organs or other complications, and a new bar was placed and stabilised. Revision showed successful correction of the thorax, and the boy had no thoracic symptoms.


Past research has ignored the impact of a casino on personal bankruptcy rates over time. Using simple descriptive statistics and regression analysis, this study examines the impact of casinos and casino tenure on bankruptcy rates from 1990 to 2002. This analysis indicates that, after an initial increase in personal bankruptcy rates, counties that legalized casino gambling experienced lower personal bankruptcy rates during the first several years of casino operations. However those rates then increase, rising above those of non-casino counties after nine years of operations. By the thirteenth year of casino operations, the estimated bankruptcies per 1,000 population are 6.7 for counties that added casinos compared to 5.2 for a non-casino counties. For the period of time covered by this analysis, this amounts to a compound annual growth rate in personal bankruptcies which is 2.3 percent higher for the county that added a casino than for an equivalent non-casino county.


In order to induce the negative impact of irrelevant place names on geographical relevance,the authors proposed a geographic information retrieval(GIR) ranking method to reduce the impact which was based on document placenames-aware.Proposed method was not fixed on a MBR(minimum bounding rectangle),but all of the placenames which appeared in a document would calculate the relevance with query scope respectively.Experimental results show that the proposed approach can outperform baselines which are based on determining the MBR's model and pure textual model of tf-idf.


This clinical otopathology textbook prepared by Prof I. Friedmann of England is composed primarily of self-explanatory and well-reproduced clear photomicrographs together with pathological descriptions. The book has an extensive reference list for further reading that is helpful for the study of otopathology for graduate-level people and resident physicians in otolaryngology. Two major sections are: (1) general pathology of the ear, which illustrates the changes caused by inflammatory diseases, neoplasms, and systemic bone diseases and otosclerosis; and (2) inner ear pathology, which includes developmental disorders, and endocrine disorders, vascular diseases, different forms of acquired deafness, ototoxic involvement, the effect of aging, and Meniere disease. The inflammatory diseases, neoplasms, and embryological and developmental disorders are well described based on the extensive background of the author as a renowned clinical and experimental pathologist. Inclusion of many electron micrographs that explain more details is another feature of this textbook. On the other hand a


Objectives: To detect and typing the HPV DNA in epidermodysplasia verruciformis (EV) and EV tumor specimens in our department during the recent 10 years. Methods: Thirteen samples from 10 patients of EV or EV tumor were examined for the presence of HPV DNA using a pair of universal primers FAP59/FAP64 designed from two relatively conserved regions of the L1 open reading frame of most HPVs. Then the amplified DNA was sequenced. The obtained DNA sequences were then submitted to GenBank and compared with the HPV DNA sequences in the EMBL Databank to identify the HPV types. Results: The positive percentage of various subtypes of HPV was 53.8%(HPV 5), 7.7%(HPV 38,47 and 22),and 15.4%(HPV 5,14) respectively and 2 different HPV types(HPV 5,14) were detected in 2 samples(15.4%). Conclusions: Our results indicated that HPV 5 is the most prevalent HPV type of EV and EV tumor. Other HPV types including 3, 14, 22, 38, 47 may be detected occasionally. One patient is infected by both HPV 5 and HPV 14.

A CCD sensor with 42 x 28 degrees FOV and 576 x 384 pixels was built by the Advanced Technology Program (ATP) in the Physics Department at LLNL. That sensor, called the StarTracker camera, is used on the Clementine Lunar Mapping mission between January and May, 1994. Together with the Stellar Compass software, the StarTracker camera provided a way of identifying its orientation to within about 150 microradians in camera body pitch and yaw. This presentation will be an overview of basically how the Stellar Compass software works, along with showing some of its performance results.


Biopharmaceuticals are among the most sophisticated and elegant achievements of modern science. The huge, complex structures of these drugs don't just look extraordinary in the 3-D modeling systems used to design them; they also perform their jobs remarkably well, offering high efficacy and few side effects. And there is much more to come: existing treatment archetypes are evolving and becoming more sophisticated all the time, and continuing research is yielding entirely new types of products. Radically new concepts are making it to the market, such as the cell therapy Provenge, which is used to treat cancer, and, somewhat further out, gene therapies, which offer even more amazing promises of regenerative medicine or disease remission.


The article deals with results that confirm the possibility of time-of-flight PMD-cameras application for short-distance measuring (0.2-5 m) to water surface. Main features of the PMD-technology are considered. Developed experimental setup is presented. An experiment, confirming the efficiency of PMD-cameras under natural conditions is described. Experimental 3D-images of water surface shape are presented with corresponding explanation. Graphical results of statistical processing of valid pixels of 3D-images are presented. 3D-image processing algorithms are proposed for estimate of distance. The results may be useful in solving the problems of liquid level measurement, determining the parameters of sea waves and measuring the height of the movement of object above the water surface.


Pepper plants (Capsicum annuum L.; hybrid Latino) were grown at temperature regimes of 29/20 and 25/14 (˚C, day/night) and the variables previously related to the cold acclimation process in temperate plants were studied. After 60 days of treatment, plants cultivated at the low temperature regime showed a 50–70% reduction in shoot length, leaf number and shoot dry weight in comparison with the high temperature regime. Root dry weight was not different between the two sets of plants, and the plants grown in the cold regime showed an increased number of axillary shoots. Analysis of the leaves at four different positions in the canopy (below the first bifurcation of the plant and in the first, second and third bifurcation) showed that chlorophyll and soluble protein content decreased with plant age at both temperature treatments, but absolute values were higher in the leaves of plants grown at low temperature, especially in the two upper leaves. The difference in the protein content could be explained by different leaf content of soluble Rubisco enzyme. Total nitrogen content was slightly higher in the leaves of plants grown at low temperature, but the percentage of the nitrate form was lower in this condition. In relation to carbohydrates, the sucrose content was lower in the leaves of the cold regime plants, except in the youngest one, whereas the starch was higher in the leaves of these plants, specially in the two upper leaves. Finally, plants grown at the lower night temperature showed an improved chilling resistance when exposed for 4 nights at 6˚C, as estimated by visual rating and measurement of leaf electrolyte leakage. The level of cold tolerance observed was similar to the level obtained in plants grown at optimal temperature treated with paclobutrazol, a plant growth regulator that ameliorates chilling stress symptoms. Differences in carbon and nitrogen metabolism are discussed in relation to the cold acclimation process of pepper plants.


Experimental data on the effect of nicotine on cerebral microvessel thrombosis is lacking. Therefore, this study was carried out to elucidate effects of nicotine on platelet aggregation in cerebral (pial) microcirculation of the mouse, and the possible protective effect of Vitamin C and E. Male TO mice were divided into six groups, and injected i.p. with saline as a control, Nicotine (1mg/kg), vitamine C alone (100mg/kg), vitamine E alone (100mg/kg), nicotine plus vitamine C or nicotine plus vitamine E, all for one week before the experiment. After one week, platelet aggregation in cerebral microvessels of these groups of mice were carried out in vivo. Appearance of 1st platelet aggregation and total blood flow stop in venules as well as arterioles were timed in seconds. Results illustrate that in the animals treated with nicotine, venule did not show any alteration in the platelet aggregation timings in comparison to the control animals. But in arterioles platelet aggregation timings were significantly accelerated (p<0.001) in nicotine treated animals as compared to controls. Both vitamins C and E prevented the shortening of arteriolar platelet aggregation time significantly (p <0.001) when applied with nicotine but not alone. Data shows the adverse influence of nicotine on the susceptibility to thrombosis in the cerebral arterioles, in vivo. The enhanced initiation of thrombosis activity may be attributed to nicotine thromboembolic activity. This study shows that antioxidant vitamins C and E have alleviating effect on nicotine induced thrombotic events in mice pial microvessels.


The popularity of deconstructivist architecture around the world has invited controversy over the sensationalist design of these buildings. New urbanists, in particular, have criticized decon architecture as alienating and disorienting. From a historical perspective, this opposition between deconstructivists and new urbanists is the latest in a long line of debates over what constitutes "good design." Using a political-economy approach based on the work of Karl Polanyi, this article examines a centuries-long dialectic in design ideology between those who seek to embed design in social mores and those who attempt to "disembed" it from oppressive discourses. This analysis shows that the dialectic of design movements is intimately connected to the development of capitalist markets.


The purpose of this study was to determine the strategic planning practices at Plan International, Kenya Office (Plan Kenya) and the factors that influence such practices. The study was done through a case study of Plan Kenya. Plan Kenya is a branch of Plan International Inc., which according to the Non-Governmental Organizations Co ordination Act, 1990, is an international NGO. There were 5,461 NGOs as at August 2008 registered by the NGO Co-ordination Board and the number was growing at a rate of 400 per annum. All these NGOs depend on the donations for their survival. This has created stiff competition for donations from foreign governments, corporate and individual donors. In order to improve competitiveness, NGOs are becoming more organized in the way they conduct business. Strategic planning practices are being adopted by NGOs as a demonstration of good planning practices and accountability. The study found out that strategic planning practices are applied consistently at Plan Kenya through the performance of all the five critical components. The five critical components in strategic planning are; the formulation of vision and mission statements, performing situation analysis, evaluation and making strategic choices, implementation of strategies and evaluation and control of strategy implementation. Plan Kenya performs all the four of the five in great in a much formalized way. However, the vision and mission statements are formulated by the parent organization for implementation by all Plan International offices worldwide. The whole process is well documented in the internal documents.


This paper describes a scientific workflow for ab initio calculations of elastic coefficients (Cij) of crystalline materials implemented in the VLab Cyberinfrastructure [da Silveira et al., 2008]. This workflow has recently been upgraded to treat crystals of all symmetries and integrated in the XSEDE. First we review the underlying Cij calculations and list explicitly different requirements for each Bravais lattice. We also describe the workflow management and its general method for handling actions. We illustrate the Cij application with a calculation of diamond's elastic coefficients at high pressures. We conclude with an outlook of future implementation plans.


The influence of mechanized cutting time on the yield and quality of hops was studied for three years (2007, 2008 and 2009) in three Czech hybrid varieties Harmonie, Rubin and Agnus. The cutting term classified as 'early' was carried out at the turn of March and April. Further cutting dates were made at intervals of 7–10 days and they were classified as 'middle' and 'late' ones. Yield and contents of alpha acids were evaluated during the machine harvest. The measured data revealed no statistical relationship between term of cutting, alpha acid content and yield in any of the tested cultivars. However, during the experimental period considerable interannual differences were observed, especially in the yield. Average yield in the range of 2.0–2.5 t/ha in the period 2007–2008 decreased to 1.2–1.9 t/ha in 2009 due to downy mildew attack. On the basis of the obtained data it can be recommended to cut the hybrid varieties Harmonie, Rubin and Agnus in the first ten days of April, taking into account other factors such as age and the location of hop garden and current weather conditions.


In recent works, it has been observed that cardiac sympathetic innervation contributes to the hemodynamic adaptations of the cardiovascular system, in relation to numerous needs. Orimo et al, through the use of scintigraphy with MIBG, showed in Parkinson's patients a marked reduction in myocardial uptake of MIBG corresponding to cardiac sympathomimetic denervation, in relation to the severity of the disease.
 The aim of this work was to evaluate the morpho–functional variations of the heart at a programmed sympathomimetic stimulus (dopamine test), both in healthy patients and in those suffering from Parkinson's disease.

 At the University Cardiology "La Sapienza" of Rome, Pontine Polo, 10 patients affected by PD (age 56±5,5, of which 6 M and 4 W) and 10 healthy (54±6,4, of which 6M,4W)were tested in the absence of cardiovascular FR; all patients performed: blood chemistry, ECG, chest x–ray, Eco–TSA, tilt test, echocardio– Dopamine (2D–stress) and MIBG Scintigraphy. 2D–stress echocardiogradia was assessed by t–student of F.acc + EF + left and right diastolic times + GLS + Tapse + PAPS at 10, 20.30.40 µ dopa and their correlation (r–pearson) in the two groups.

 The observation of the data in the two groups of patients, in the absence of ongoing and remote cardiological pathology, showed a behavior of the values in the range both in basal conditions and during dopa stimulation. The comparison of the two groups both basal and during progressive dose stimulation that a statistical difference (P < 0.05) is observed on both systolic and diastolic function. The comparison in the two groups in the different stimulus phases showed a parallel growth behavior but with a different speed (Dp / Dv). There is no single explanation for these results: certainly the central role is played by the poor representation of post–ganglionic nerve endings as well as by the significant reduction of cardiac adrenergic receptors in Parkison.

 The small number of patients and the data observed, stimulates researchers to continue the study, to better understand which pathophysiological mechanisms underlie these observations and verify the presence of an inverse relationship between PD and all those cardiological pathologies caused by catecholaminergic hyperstimulus.

The emergence, formation and development of the institution of reconciliation of the parties as a means of resolving legal conflicts have a long history.
The origins of reconciliation were primarily laid down in rituals, and later were reflected in laws. At the same time, the institution of reconciliation is mentioned in almost all major history law documents - from Russian Truth to the Judicial Statutes of 1864.Thus, the article shows the development of the institution of reconciliation in Russia from ancient times to the end of the 19th century. The traditions of brother-making and refusal of blood feud are replaced by the procedure for apologizing and filing a reconciliation petition.
The article shows how the complication of social relations gradually changed the position towards crime – firstly it was perceived as an insult to a person, but with the strengthening of state power it was seen as an unlawful act, violation of the norms established by the state, where the latter is almost always considered the main victim. This, accordingly, affected the change in attitudes towards the institution of reconciliation – from stimulating the rule-maker to the peaceful settlement of criminal-legal conflicts by the parties to the establishment of a ban on reconciliation in most categories of criminal cases.

DNA ploidy of tumor cells is one of the important indicators of prognosis in human malignancies, while most cancer patients with aneuploid tumors have a poor survival rate. The exception to this concept was observed in pediatric neuroblastoma by Look et al. in 1984 [1]. They showed that the hyperdiploidy (aneuploidy) in tumor cells was correlated with a better response to chemotherapy and a more favorable survival, particularly in infants under 1 year of age even with unresectable neuroblastoma. Furthermore, in a POG study in DNA ploidy patterns of tumor cells from 298 neuroblastoma patients, diploid, hyperdiploid and hypodiploid were observed in 34% (101 cases), 65% (194 cases), and 1% (3 cases), respectively, and DNA ploidy patterns had a highly age-dependent in ̄ uence on prognosis. In 100 infants with neuroblastomas under 12 months of age at diagnosis, 79 hyperdiploid (aneploid) cases had favorable prognosis, while 21 diploid cases showed unfavorable prognosis. In children from 12 to 24 months of age with progressive diseases, nearly 50% of hyperdiploid cases responded to chemotherapy, whereas all diploid cases did not. In children older than 24 months of age with progressive diseases, however, there was no correlation between DNA ploidy patterns and prognosis. Thus, the authors concluded that DNA ploidy patterns in neuroblastoma provide complementary prognostic information that will distinguish patients who require intensive treatment strategies [2]. In general, there have been many reports related to tumor cell ploidy and prognosis in neuroblastoma. Some papers indicated that patients with an aneuploid tumor and a low cellular proliferative activity had subsequently better response to chemotherapy than patterns with a diploid tumor.

In this work, iminodiacetic acid-functionalized graphene oxide (IDA@GO) is prepared and used as a nanocollector for enhancing and selectively recovering Pb(II) from a strongly acidic waste electrolyte via ion flotation. IDA@GO is characterized by Fourier transform infrared spectroscopy, zeta potential measurements and atomic force microscopy. The effects of pH, reaction time, cetyl trimethyl ammonium bromide (CTAB) dosage and aeration rate on the Pb(II) concentration and turbidity of the residual solution are examined systematically. The experimental results show that the adsorption capacity of Pb(II) on IDA@GO can reach 91.21 mg/g at pH 2. After froth flotation, the turbidity of the treated solution decreased to 0.55 NTU under the optimal CTAB dosage and aeration rate. In addition, as compared with GO, the relative selectivity coefficients of IDA@GO are up to 1.304, 1.471, 1.807 and 1.509 for Co(II), Ni(II), Zn(II) and Cd(II), respectively, thereby exhibiting better selectivity performance. Moreover, IDA@GO can be reused as a nanocollector in ion flotation and exhibits ideal regeneration performance. In addition, the recovery mechanism is found to proceed through Pb(II) adsorbing on IDA@GO by electrostatic attraction, ion exchange and surface complexation, with the addition of CTAB improving the hydrophobicity of Pb(II)-loaded IDA@GO flocs, thus achieving the recovery of Pb(II) via froth flotation.


The threats that climate-change-induced sea level rise pose to coastal communities can be assessed using coastal vulnerability models. In order to be effective, such models require accurate estimates of shoreline position. Such data are rarely available in developing countries. Here, we develop a simple approach based on image thresholding and subsequent vectorisation of Sentinel-1 SAR data for a complex intertidal zone in the Niger Delta, Nigeria, and show how shoreline position varies over space and time under different tidal conditions.


The Center Street and McKnight Boulevard project was a collaboration between the City of Calgary's Major Road Reconstruction Program and the Transit Priority Program. The focus of the Major Road Reconstruction program is to rehabilitate major roads in the City of Calgary that are past their life cycle and in need of repair. Centre Street North was on the list for rehabilitation, which provided the perfect opportunity to collaborate and construct queue jumps at McKnight Boulevard to assist Calgary Transit buses bypass the queues at the McKnight intersection. This project improves the City's existing infrastructure and directly impacts thousands of daily commuters using Calgary Transit along this corridor. The implementation of Transit Priority Measures (TPMs) are strategic in nature and typically include detailed analysis considering both costs and benefits. This paper describes the planning and implementation of a significant transit priority measure in Calgary from the planning to the construction phase. In addition to providing specific project details, a brief history of transit priority measures in Calgary is also provided.

Sir, We would like to bring to the readers' attention a pragmatic method of securing surgical drains. Skin stay sutures are conventionally tied around the drain to prevent dislodgement. Various modifications have been described, each technique endorsed by its proponent as being foolproof. For example, O'Flynn et al. suggested passing a suture through the drain and anchoring on the skin with beads and crushed metal stoppers. Hormbrey et al. described the technique of passing a non-absorbable stay suture through the drain and tying a firm knot over it. The resulting 'waisting' of the drain prevents slippage, although care must be taken with fine drain tubing that the process of 'waisting' does not occlude the lumen. Conversely, considerable force may be required to pass a suture through a wider drain. The slippery drain may prove awkward to handle, and thus predispose the surgeon to needle-stick injury. The process of passing a suture through the drain also disrupts luminal integrity; causing tube kinking, a focus of infection and formation of clots. Once the drain has been appropriately sited, cut a short length of the tubing. This is possible as there is usually redundant length of drain. Deliver a non-absorbable suture through a hole near the edge of the drain (Fig. 1). Proceed into the cavity and pass the suture although the most proximal holes of the drain. Then, exit the cavity and finally through a hole on the opposite end of the drain segment. Before securing the stay suture, ensure no further movement of the drain can occur. The proximal holes should be adjacent to the under surface of the skin flap. The fastidious surgeon may also elect to place a piece of surgical foam under the drain segment to reduce the risk of pressure necrosis. This method is simple to perform when compared with the waisting technique, where there is a risk of tying the knot too tight and potentially breaking the suture in the process. In our experience, there is minimal movement when drain is pulled taut. Thus, the problem of losing a vacuum condition is not a feature as the proximal holes are secured in the cavity by the stay suture. In contrast to Jayarag et al. who secured the drain segment to the distal holes, our method allows the drain tip to be freely positioned in deep cavities. We believe that this technique can be easily learnt by trainees, whose usual responsibility is to secure the drain at the end of the operation. Poorly taught or complicated technique remains the bane of juniors who are keen to please. Even if this adage remains true these days, the established surgeon may find the above method both useful and professional. We are in no way disseminating novelty, and commend Lim et al. for describing the technique. Nevertheless, greater awareness amongst the ENT audience is justified because of its simplicity and effectiveness. Leong, S.C.L. & Mortimore, S.

The behavior of transition metals (TMs) in silicon is a subject that has been studied extensively during the last six decades. Their unintentional introduction during the Si production, crystal growth and device manufacturing have made them difficult contaminants to avoid. Once in silicon they easily form deep levels, either when in the isolated form or when forming precipitates. One important effect is the reduction of efficiency of silicon-based devices, being dramatic, in particular, in photovoltaic applications. One way to avoid such effects is by engineering the location of the TM: some TM complexes or lattice sites of the isolated form do not introduce any level in the silicon bandgap. Which point defects lead to such passivation is still under debate. Another way is to mitigate the reduction of efficiency by reducing the dangling bonds of TMs with hydrogen. The most important and commonly used procedures to diminish the unwanted effects of the introduced deep levels are, nevertheless, based on the so-called gettering techniques, where TMs are forced to move away from the active area of devices. Although the macroscopic effects of all the gettering techniques are well known, the related microscopic mechanisms are still poorly understood, namely the TM complexes involved in gettering into defective regions, into p-type layers and by phosphorus diffusion. TMs can also be used as magnetic dopants in semiconductors. So far, only binary semiconductors have been intensively addressed, after the discovery of dilute ferromagnetism of (Ga,Mn)As. However, the maximum found Curie temperature was only 185 K, which is too low for practical applications. Other semiconductors have hence been recently suggested, such as silicon. One important feature is the lattice sites occupied by TMs, and related fractions. It is currently well established that the incorporation of TMs on substitutional sites leads to thermally stable point defects with none-zero magnetic moment. One way to obtain substitutional TMs is by ion implantation. Which fraction is incorporated on S sites is, however, still unknown. All these issues can be explored by investigating the lattice sites of implanted 3d TMs. In particular, different complexes will correspond to different lattice sites. Here, we have investigated the lattice location and thermal stability of the implanted 3d TM probes Mn, Fe, Co and Ni in both lightly and heavily doped nand p-type Si by means of emission channeling experiments. In all cases we identified ideal substitutional (S) sites, displaced bond-centered (near-BC) sites and displaced tetrahedral interstitial (near-T) sites.


Pure Mucinous carcinoma of the breast is relatively rare, accounting for 2% of all breast cancers. Commonly presenting in postmenopausal age group. Here we report 2 cases, postmenopausal age group female patients, presented with lump in the unilateral breast. On fine needle aspiration cytology, diagnosis of mucinous or colloid carcinoma of the breast with no lymph node metastasis was made and subsequently confirmed by Histopathology. Knowledge of the distinctive cytomorphological appearance of Mucinous carcinoma would enable correct identification of these lesions as malignant and prompt treatment that could further enhance the survival of these prognostically good breast cancers.


Compact measurement setup and test structure for nanosecond electroporation of biological cells were demonstrated. The test structure was based on a coplanar waveguide with a defected ground structure that afforded broadband impedance match with little dispersion or parasitic. The defected ground structure with a 10-µm gap formed a microchamber to readily accept biological solutions and to allow the measurement to be quickly performed before the solution evaporated or the cell activity changed. The measured results in conjunction with detailed electromagnetic analysis of a three-layer spherical cell model showed that the present measurement setup was capable of delivering a nanosecond 0.1-V potential across a plasmatic membrane. This transmembrane potential, although an order of magnitude lower than the typical threshold for membrane poration, could be increased by using nanosecond pulses with order-of-magnitude higher amplitude or 10-ns pulses with three times higher amplitude.


The rebo-wekasan tradition is one of the traditions which until now is still practiced by the Muslim community of Nusantara, both on the island of Java and outside Java. The tradition of rebo exertion in the archipelago is practiced with various rituals that are carried out, such as: prayer, prayer, pilgrimage, bathing and charity. But the diversity of these rituals has the same purpose, namely that the perpetrators be given salvation from all kinds of dangers and calamities especially those that are in the month of Safar. This study aims to reveal the history and practice of traditional ritual rebo rituals and explore religious texts originating from the Prophet's hadith which are guidelines or steps for Ya>si>n and santri in implementing the rebo wekasan tradition at MQHS Islamic Boarding School Al-Kamaliyah Babakan Ciwaringin Cirebon . This study uses the theory of living hadith, with a historical-theological approach and phenomenology. The method used is qualitative, and data collection techniques by conducting observations, interviews and documentation.


I s JOURNALISM an art or SCIence? There's a question that could lead to unlimited, and probably fruitless, argument. In actual practice I think we would finally agree that it is a combination of both, perhaps with emphasis on the side of art. Still in the end we might have to confess that the answer is of neither great nor immediate significance. Stated another way, however, the question takes on an altogether different import. It permits no begging, it invariably arises whenever journalists discuss academic matters with their academic colleagues, and sooner or later it will demand an answer. In restated form: Are journalistic practices and policies actually reducible to basic "rules" and "prineiples"?Really, just how suitable is journalism as a -field for teaching and research? Half of that question has long since been answered. Journalism is being taught in colleges and universities throughout the nation. Journalism schools and departments are winning increasing respect for their work, are annually turning out! graduates who prove by their achievements that they have heen adequately trained. But how about research? Journal-ism has not been admitted in full confidence to collegiate research circles. Except in one university, alI research on the doctoral level is being carried on through other departments. Perhaps the explanation is not so much that journalism is being mistreated as that we have not yet made clear to those in other fields the scope of journalism, its relation to other social studies and the consequent place of journalistic research. ," This has happened before in the academic world. Educators faced somewhat the same question nearly two decades ago, when in the orphan . field of pedagogy they found it necessary to take some time in outlining the place of the school of education and of research to seek underlying rules and principles upon which effective teachingIs based. There are many parallels between education and journalism. Both are sciences of communication. Both deal with the task of transmitting information, guidance, counsel, emotional attitudes and ideas from one mind to a number of others. As "communicative, studies," both stand apart from other fields of inquiry, So perhaps there is another parallel between the sources upon which to draw and the problems which arise in teaching and research in the two fields. In 19~9 John Dewey published some significant conclusions in a


Adsorption and photocatalytic degradation of 4BS dye over fine particulate TiO2 are studied in an opened batch slurry reactor. The influences of mixing of solid–liquid and external diffusion on degradation rate are eliminated by increasing stirred rate. The adsorption experimental results indicate that pH and temperature of solution affect adsorption considerably, a Langmuir equilibrium adsorption isotherm can be used to described them. Meanwhile, catalyst dosage, reaction time, pH of solution, stirring speed, initial concentration, direct irradiation area, and illumination intensity of UV light can affect the reaction rate. Favorable pH for 4BS dye degradation is about 3.5, suitable dosage of catalyst is about 1.0 g • L−1. After numeric analysis to experimental data, a kinetics model is established; the rate constants are different for catalyst dosage in 0.5 g • L−1 or 1.0–6.0 g − L−1.


The safe and stable operation of the converter transformer is of great significance to the power system. The vibration signal on the surface of the converter transformer tank can well reflect its internal operating state. However, the vibration signals of the core and winding of the converter transformer are highly correlated, and there is a phenomenon of frequency aliasing. This paper proposes a blind source separation algorithm for the vibration signal of a single-channel converter transformer based on CEEMDAN-KPCA. The reliability of the algorithm is verified by means of simulation signal separation, actual converter transformer measurement signal analysis and unoptimized algorithm separation effect comparison, which is of great significance to converter transformer fault monitoring.


Dinner Party is an interactive installation, where a single chair and a place set for one person seem to provide a solitary dining experience. However, the installation offers an interaction between oneself and imaginary creatures. As if she or he is about to enjoy a meal, a participant sits down at an interactive table on which are placed several objects that he or she can move. The objects cast virtual shadows on the tabletop, with animated creatures hiding in these shadows.


Using quantitative and qualitative research methodologies, the current study examines Saudi students' perspectives, coupled with EAL instructors' views, regarding Saudi students' English language-learning needs. Two data collection tools were used, a questionnaire and semi-structured interviews. The study (N = 172) included samples of EAL learners (n = 127) and EAL instructors (n = 45) both in Saudi Arabia and Canada, Victoria. The mismatch between the skills identified as important and areas identified as needing support by the learners, in addition to the divergence between learners' and instructors' perceptions, underscores the necessity of triangulation when using needs analysis to discover language-learning needs. The study delineates oral communication (i.e., being able to interact by using the language appropriately and efficiently) as a language-learning need identified by both Saudi students and their language instructors. Quantitative (skill ratings) and qualitative (responses to openended questions and interviews) data suggest that both students and instructors view writing as a challenging area for Saudi English-language learners. The results also indicate issues that contribute to the challenges faced by Saudis in the process of learning English. Findings show the importance of educational background and cultural differences in the students' language development. Responses report that reading is devalued in the Saudi educational system and Saudi culture in general. Hence, both Saudi students and instructors in Canada pinpointed reading as an area needing support. Based on the key findings, it is evident that the language-learning needs of Saudi students are shaped according to the requirements of their immediate study context and their prospective goals. The study contributes crucial findings about participants' perceptions of the importance of skills and their assessment of skills status in Saudi Arabia and Canada. In addition to the implications for English language learning in Saudi Arabia, these findings can be informative for educational institutions and practitioners in the English-speaking world. Most importantly, the multi-level analysis confirms that language learning needs are context-specific.
