Background:
 The incidence of anomalous aortic origin of the right coronary artery (AAORCA) is between 0.026% and 0.25%. There is limited data regarding medical versus surgical management. We present a case of AAORCA which did not "qualify" for surgical intervention but remained symptomatic on medical management.

 Presentation:
 A 58-year-old female with paroxysmal atrial fibrillation presented for the eighth time in the past two years with recurrent atypical chest pain and lightheadedness. Vital signs and cardiac biomarkers were normal.

 Work-up:
 EKG showed normal sinus rhythm. TTE revealed EF 68%. Myocardial perfusion imaging was normal but exercise stress test showed ventricular ectopy, ventricular bigeminy, short bursts of ventricular tachycardia (VT) at peak exercise, and a 7-beat run of VT. A 30-day event monitor revealed a 17-beat run of VT at a rate of 173 bpm (Figure A).

 Management:
 Cardiac catheterization showed the dominant right coronary artery (RCA) arising from the left coronary cusp with a shared ostium to the left coronary system (Figure B-D). A coronary CT scan confirmed dominant RCA arising from left coronary cusp (Figure E) with an interarterial course (Figure F) and slit-like appearance of the proximal RCA, with a likely intramural course (Figure G).She was managed conservatively with restriction of vigorous exercise, up-titration of beta-blockers, addition of anti-anginal agents and implantation of loop recorder.

 Conclusion:
 The most updated consensus statement for AAORCA recommends surgical intervention for those with signs or symptoms of myocardial ischemia (true angina, findings on provocative testing, aborted sudden cardiac arrest or non-vagally-mediated arrhythmia).Although our patient did not "qualify" for surgical intervention, she continued to experience refractory symptoms. Hence, it is of utmost importance to consider surgical intervention in patients who have failed medical management, for improved quality of life.


The essay focuses on J-L Nancy's proposal to interpret the categorical imperative. He conceives the categorical/hypothetical pair in the light of Aristotelian-scholastic logic, asserting: categorical is an absolute affirmation of the predicate of a subject, while hypothetical corresponds to the conditional affirmation of a predicate for a subject. J.-L. Nancy doesn't only refer to this, but he is also interested in the practical power of the categorical order of transcendental logic, in the prescriptiveness of that order or, to be more precise, in its self-prescriptiveness. This order is "the order of the relationship between existents" centrality of kategorein in the field of praxis, Nancy considers the Kantian expression "universal law of nature" essential to identify the meaning of the formulation of the categorical imperative. This meaning will be illustrated with a double argumentative movement: the comparison with Kantian ethical works (Foundation of the Metaphysics of Customs and Critique of Practical Reason, in particular Preface and Typical of pure practical judgment), on the one hand, and the analysis of the critique that Nancy makes of subjectivist or "egotistic" interpretations of the universalisation of the categorical maximum, on the other. This will be connected with reflections on the complex relationship between the coercive imperiousness of command and freedom.


On the basis of researching definition and measurement method of roundness error of shaft parts, the evaluation model of roundness error based on genetic algorithm with transfer-operator is established. By means of a new idea based on genetic algorithm with transfer-operator for roundness error which meets the minimum zone method, traditional genetic algorithm was made some suggestions for improvement. The global optimization can theoretically be acquired. The simulation results show that the method is valid at variable global scope, and can correctly evaluate the roundness error of shaft parts.


A method of abortion by vibrodilatation of the cervix followed by vacuum aspiration of the contents of the uterus, employed by the authors since 1966, is presented, and experience with 4682 cases is reported. The techniques and instrumentation developed for these procedures are described in detail. Vibrodilatation of the cervix offers the advantages of speed, reduced risk of infection or injury, and a high success rate. Vacuum aspiration combines the desiderata of speed, a smaller loss of blood, reduced anesthesia, and a greatly reduced rate of postoperative complications. Precautionary procedures are discussed, and recommendations concerning the use of these techniques are given. In particular, they are not recommended after week 10 of pregnancy.

Tree-ring analysis is a useful technique able to illuminate many areas of paleoenvironmental research. Most regions of Canada have been investigated to some degree using dendrochronological methods, but by far the least studied region is Atlantic Canada. This presentation will highlight positive and negative aspects of conducting dendrochronological research within the Atlantic Coast region with an emphasis on understanding past climates. Results from initial work establishing long-term chronologies will be discussed, as well as unique methodological approaches incorporating tree-ring samples from several sources. Extensive historical and paleobotanical sources are probably the only means of extending tree-ring records back far enough to produce the kind of long-term annual-resolution models common elsewhere in Canada. By using these methods, useful proxy models of climate can fi nally be developed for the region to more fully understand past environments, and to better predict future climates through regional and global circulation models.

The influence of miscibility on the transport properties of polymer electrolyte blends composed of a proton conductor and an insulator was investigated. The proton- conductive component in the blends was sulfonated poly(ether ketone ketone) (SPEKK), while the nonconductive component was either poly(ether imide) (PEI) or poly(ether sul- fone) (PES). The phase behavior of PEI-SPEKK blends was strongly influenced by the sulfonation level of the SPEKK. At low sulfonation levels (ion-exchange capacity (IEC) ¼ 0.8 meq/g), the blends were miscible, while at a slightly higher level (IEC ¼ 1.1 meq/g), they were only partially miscible and for IEC � 1.4 meq/g they were effectively immisci- ble over the entire composition range. The PES-SPEKK blends were miscible over the entire range of SPEKK IEC considered in this study (0.8-2.2 meq/g). At high IEC (2.2 meq/g) and at low mass fractions of SPEKK ( 0.5). This behavior was explained by the differences in morphology between these two blend systems. At low IEC of SPEKK (0.8 meq/g), where both PEI-SPEKK and PES- SPEKK blend systems exhibited miscibility, the transport properties were not significantly


The subject of this thesis depends on intuitionistic fuzzy BCK - algebras.
In the first chapter we recalled some elementary basic definitions and results on intuitionistic fuzzy sets. The second chapter is devoted to study the concept of BCK- algebras and we investigated the fuzzification of BCK-algebras and discussed some of its properties. In the third chapter we studied the intuitionistic fuzzy ideals of BCK-algebras, and we introduced the notion of intuitionistic fuzzy BCK-submodules and investigated further related properties. We introduced the notion of intuitionistic (T,S) -fuzzy BCK- submodules by using triangular norms. Also, we presented some basic results on intuitionistic fuzzy BCK-submodules with respect to triangular norms and we have investigated various properties. The concept of interval-valued intuitionistic fuzzy BCK-submodules and (∈,∈⋁q)-interval-valued intuitionistic fuzzy BCK-submodules of BCK-algebra were presented and some of their properties were investigated. These concepts and results were submitted as an articles to scientific journals, and we obtained an acceptance to publish one of these articles.


Recommender System Framework for Heterogeneous Networks Fatemeh Vahedian Center for Web Intelligence, Depaul University, Chicago, IL 60604 keyword: Heterogeneous Information Networks, Meta-paths, Recommedner System, Multirelational Learning. Social networks such as Twitter, Facebook, and Flickr can be modeled as a Heterogeneous Network with multiple node types and different types of relations among them. Recommendation, the personalized provision of items and information, is a key concern for these large-scale information ecosystems where users seek to find new information. These environments provide a wealth of data on which recommendation can be based. However, this information and its associated complexity poses two challenges for recommender systems: (1) the problem of integrating a wide variety of data effectively into a recommendation framework, and (2) the problem of responding to many potential recommendation tasks, because of the wide variety of items present. We have designed the Weighted Hybrid of Low-Dimensional Recommenders (WHyLDR) approach to address the problems of multi-target recommendation and information heterogeneity. [1, 2, 10, 7]. The main idea of WHyLDR model is to build a collection of simple recommendation components, each representing a different relation within the data. We combine the recommendation components in a weighted hybrid, and use optimization to learn the optimal weights. In a heterogeneous network there are several relation types , there is a target relation that represents the prediction to be made. This target relation can be a direct link of the network or an extended path obtained from walking through different type of nodes. For example in a Movie example the target relation can be user−movie when the desired recommendation task is movie recommendation. However, we can also imagine recommending actors to user. In this case the target relation is achieved by following meta-path user → movie→ actor. WHyLDR components are constructed from two-dimensional projection of n multi-step meta-paths in a network. There are two types of recommendation components in this model, user-based collaborative filtering [6] and item-based collaborative filtering [3], and their formation is guided by the recommendation task. In other to construct the hybrid model, we make use of Particle Swarm Optimization (PSO) [5] to learn weights for each recommendation component in hybrid model. This framework takes advantage of the normalized information gain of each meta-path to filter the less-informative. In addition, the NIG value is used in combination of the component accuracy to predict the weight of each components in weighted hybrid model. We also demonstrated the utility of extended meta-paths in matrix factorization model of recommendation [8, 9, 11]. We use the multi-relational matrix factorization model DMF from [4], in which different latent feature models are defined for each relation. The NIG can effective measure to omit the less informative meta-paths based auxiliary relations which can either cause over-fitting or increase the learning time of factorization model. As future work, we are working on weighted meta-path generation using random walk methods to add user rating values to the recommendation framework and measure the effect of those values to recommendation accuracy.


Lakoff's hypothesis about the connotations of the words "lady" and "woman" was investigated by asking college students to rate these words, as well as the masculine words "gentleman" and "man," on several adjective scales. Ratings indicated that the term "gentleman" implied greater competence and warmth than the word "man," while the term "lady" tended to suggest to raters relatively less competence and less warmth than the term "woman" did. Further, it was found that the more formal term ("gentleman," "lady") regardless of gender was described more positively than the less formal term ("man," "woman") on several scales concerned with goodness, politeness, morality, and femininity. Lakoff's hypothesis that "lady" conveys some unique meanings relative to sex role stereotypes thus received support, although some of the connotations of "lady" appear to be due to implied formality rather than to gender features. The degree to which feminine terms were differentiated by raters could be predicted to some extent on the basis of rater characteristics; no significant prediction was possible for the masculine terms.


Lead free relaxor 0.8NBT-0.2BT nano-structured ceramic composition was processed through sol-gel technique and sintered at 1140°C for 4 h in air. The bulk density exceeded 95% of theoretical density as determined by Archimedes principle. The sintered samples were characterized using X-ray diffraction, field emission scanning electron microscope, energy dispersive spectrometry, Raman, dielectric, AC impedance, piezoelectric and ferroelectric measurements. XRD patterns recorded at room temperature confirmed the rhombohedral phase formation of the samples. Particle size range measured for calcined powder was found to be of 40-50 nm and the average grain size of the final sintered sample was 80 nm. Analysis of Raman spectral data of the sample indicated distortion of NBT. The diffuse phase transition behaviour was investigated from ε versus T curve and the temperature due to structural change coincided with abrupt jump in ε(T) curve. Dielectric maximum and minimum were also evaluated to define phase transitions of 0.8NBT-0.2BT system. NBT-BT has shown normal diffuse type of phase transition. Charge transformational behaviour could be analyzed based on AC and DC conductivity measurements. Ferroelectricity was also confirmed by P-E measurements and piezoelectric constant obtained for the NBT-BT sample was 90 pC/N. GRAPHICAL ABSTRACT


We have previously reported that precursor-accumulating (PAC) vesicles found exclusively in developing seeds are involved in a transport of seed storage proteins, such as 2S albumin, from the endoplasmic reticulum to protein-storage vacuoles. Here, we constructed chimeric genes that encode fusion proteins consisting of both various lengths of polypeptides derived from pumpkin 2S albumin and a selectable marker enzyme, phosphinothricin acetyltransferase. The chimeric genes were expressed in transgenic Arabidopsis in order to investigate the mechanism of the PAC vesicle formation. A fusion protein expressed by one of the chimeric genes is accumulated as a proprotein-precursor form, and localized in novel vesicles of vegetative cells. The vesicles show distinct features that well much to the PAC vesicles. Despite of the accumulation of the fusion protein, the transgenic Arabidopsis is still sensitive to phosphinothricin. Phosphinothricin acetyltransferase contained in the fusion protein is obviously compartmentalized in the PAC-like vesicles that do not permit the detoxification of this herbicide. These results indicate that the PAC-like vesicle can be induced in vegetative cells by the ectopic expression of the protein that is destined to be compartmentalized into the PAC vesicles.

There are only a few approaches in socialization theory that give empirical insights into the processes of growing up in an autocratic system. However, political regimes like the former German Democratic Republic (GDR) have (had) only limited control over private family structures. Thus, the different family backgrounds of women who were part of the opposition movement and imprisoned because they tried to (illegally) migrate to West Germany will be illustrated in this paper. The study consists of biographical narratives with women born in the 1940s, '50s, and '60s. The very different family backgrounds of these women influenced the acquired strategies to deal with the autocratic system. However, these strategies can fail or become ineffective in different life circumstances leading to biographical blockades. I argue that biographical blockades can be considered as a key concept to explain high-risk emigration decisions.


The utility model discloses a pull rod type rear suspension structure for an automotive engine, which comprises a small-end bushing component matched with one end of a rod framework. The other end of the rod framework is provided with a hollow shaft, the middle of the rod framework is provided with an auxiliary hole, a partition plate is arranged in the middle of a large-end framework, and two main rubber springs in same structures are provided with middle through holes and symmetrically disposed on two sides of the partition plate of the large-end framework. The large-end framework and the main rubber springs on two sides of the partition plate of the large-end framework are matched with the hollow shaft at the other end of the rod framework. A hollow shaft bolt penetrates through a through hole in the middle of a large-end cover plate, and the hollow shaft at the other end of the rod framework is fittingly connected with a nut which is arranged in the auxiliary hole in the middle of the rod framework. The pull rod type rear suspension structure for the automotive engine has the advantages that firstly, stress concentration of rubber can be effectively avoided, fatigue cracking is prevented, and suspension reliability is improved; secondly, independent demounting of the suspension main rubber springs is realized; and thirdly, when the main rubber springs fail, only rubber portions rather than other parts need to be replaced, so that maintenance cost is reduced.


A 60-year-old hypertensive male who had sustained an episode of syncope one year before, was admitted because of severely incapacitating shortness of breath. Physical examination revealed overt signs of heart failure and murmurs of aortic and mitral incompetence; blood pressure was 150/50 mmHg on admission. An ECG showed sinus rhythm with first degree atrioventricular block, and signs of left ventricular hypertrophy without intraventricular conduction disturbances. After conventional diuretic treatment a combined right and left heart catheterization was performed via the femoral route. Upon catheterization of the left ventricle both intermittent left bundle branch block and total atrioventricular block occurred, during which the patient briefly lost consciousness. The procedure was continued, uneventfully, after insertion of a temporary transvenous pacemaker. Angiography demonstrated normal coronary anatomy, but severe aortic and mitral incompetence.


ABSTRACT In Britain and New Zealand the neoliberal assault on universities has shifted from new public management and funding models to the special status of the public university. The project aims to complete neoliberal business initiated 25 years ago by more fully marketising and financialising universities, starting with 'unbundling' and outsourcing and culminating in new forms of privatisation, rent-extraction and rebundling. This paper analyses two documents commissioned beyond government to create political momentum for this project: Avalanche is Coming and The University of the Future. These both capture the zeitgeist of reform while simultaneously creating the university futures that they portend. We examine the market-making work they perform in reimagining and reinventing universities ahead of policy reform. We argue that claims made to support fundamental restructuring of public universities lack substance or evidence. Rather, each is underpinned by different configurations of ideology and self-interest that together envelope universities in new agendas of marketisation, financialisation and privatisation. We suggest that in this latest restructuring of public universities critics should pay more attention to the work of consultancies and think tanks alongside the micro-details of market making. By doing so, they too might reimagine public universities, but for a different political project.


Objective To investigate epidemiological characteristics and clinical prognosis of Kawasaki disease (KD) in Yunnan Province for recent 10 years. Methods The survey forms of Japan- China KD epidemiology were used and sent to the province's 130 hospitals above the county and city level with pediatric in- patients, in order to conduct a survey on the KD children during 10- years period from January 1, 1997 to December 31, 2006, totally for twotimes, once every5 years. Results 95.5% ofthe surveyforms came back. 1,662 KD cases were reported fromthe 47 hospitals of 15 districts. The incidence of KD was of an increasing trend. It was 3.51 per 100,000 in 1997, while it was up to 13.6 per 100,000 in 2006. The ratio of male and female was 1.58 to 1. The age of patients varied from 2 months to 14 years, those under 5 years of age accounted of 74.19%. The KD children from 11 minority peoples accounted for 6.4%. The disease occurred all over the year, and had no obvious season peak. Coronary artery lesions accounted for 20.64%, including ectasia(82.5%) and aneurysm(17.5%) .There was no death during acute period. The recurrence rate was 0.36%. Conclusion The incidence of KD in Yunnan is in an increasing trend. The coronary artery lesion of KD has already been one of main factors causing acquired heart disease in children. Thus, early diagnosis and treatment duringacute period is an important measure toavoid anysequel.


The green space information extraction is significant for study on urban remote sensing because of its ecological and socioeconomic functions. And with the traditional methods the precision is very low, we educe decision tree of extraction to raise the accuracy rate. We take Shanghai as a case study area from QUICKBIRD imagery, analyzing spectral characteristics of 4 multi-spectral bands. And we also introduce accessorial information vegetation index (NDVI) to get rid of other land use types. The final result suggests that the extraction method of decision tree can accurately get the green space information. The accurate rate is over 95%. It can be widely used in the field of urban vegetation remote sensing analyses.

The EU has adopted a Carbon Border Adjustment Mechanism (CBAM) that taxes imported products according to their emissions. Despite its importance in aligning incentives for decarbonisation between the European and global levels, it carries a double risk: reducing the competitiveness of European exports and raising the prices paid by consumers within the EU. In this policy brief we analyse both issues for Spain, noting that the most affected sectors would be the automotive and metalworking industries. For the agri-food industry, despite being another of the leading sectors in our international trade, the effect would be more moderate. Finally, the impact on households would be small and slightly progressive, with higher-income households, especially those in rural areas, facing higher costs.


A more convincing physiologic experiment could scarcely be devised as illustrative of the recuperative power of the human heart than the restoration of cardiac function following acute coronary occlusion. That it is possible for the human heart to reestablish its intrinsic blood flow, both through collateral vessels and through channels other than the coronary tree, is now well established and undoubtedly is an important factor in aiding recovery in cases of cardiac infarction. Allbutt, 1 Wearn, 2 Scott 3 and others have reported cases of complete occlusion of the coronary orifices from syphilitic aortitis in which no serious myocardial change was present. In these cases a gradual occlusion of one or both coronary orifices over a period of months was so completely compensated for that the patients were able to continue their daily work with comparative ease. It is quite apparent, therefore, that if the initial shock of acute cardiac


One of the two most important criteria in evaluating the quality of a psychological test is validity in its broadest sense (the second criterion, of course, is reliability); validity refers to the degree of correspondence between what is ascribed to the test, and what the test actually represents.


Background: Recent changes across the world with respect to gender transitioning of children and adolescents have generated a bio-psycho-socio-cultural discourse among interest groups. Aim: This study sought to examine gender dysphoric symptoms among adolescents and young persons in an African population, using a dimensional approach. Method: A total of 747 primary/secondary school and university students aged 10–24 years were studied using the 27-item Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA). Participants were divided into early, mid- and late adolescents. The composite and domain scores were calculated using the criteria described by Deogracias, and comparison of the median scores was done using Mann–Whitney U-test and Kruskal–Wallis test as appropriate. Dunnett's post-hoc test was used for pairwise comparisons. Results: The prevalence of self-identified transgender and self-reported non-heterosexuals was 0.9% (95%CI: 0.36–1.92) and 18.6% (15.85–21.59), respectively. The participants as a group scored 4.56 out of a possible 5 on the gender dysphoria scale, indicating less gender dysphoric symptoms in this cohort. However, participants in mid- and late adolescents had significantly lower scores when compared with early adolescents (P = 0.009). Self-reported transgender had significantly lower scores in the social (P = 0.001) and socio-legal (P < 0.001) indicators of the scale. Conclusion: The findings of this study, although, preliminary demonstrated less gender dysphoric symptoms in this cohort of Nigerian adolescents and young adults compared to the Western population. Nevertheless, some degree of GD was noticed, revealing that this condition is existent in our society.


Nano-CeO2–reinforced NiCoCrAlY coatings were fabricated on Ti6Al4V alloy using laser cladding. The morphologies, chemical compositions, and phases of obtained coatings were analyzed using a scanning electron microscope, energy-dispersive spectrometer, and X-ray diffraction, respectively, and the effects of nano-CeO2 mass fraction on the coefficient of friction and the wear rate of NiCoCrAlY coating at 600 °C were investigated using a ball-on-disk wear test. The results show that the nano-CeO2–reinforced NiCoCrAlY coating is mainly composed of NiTi2, Ti3O, CoO, and β-Ti phases, while the new phases of AlTi3 and (Ni, Co)2Ti4O are formed after the wear test. The average coefficients of friction of NiCoCrAlY coatings with the nano-CeO2 mass fractions of 0%, 2%, 4%, and 6% are 0.699, 0.655, 0.636, and 0.615, respectively, and the corresponding wear rates are 4.04 × 10−7, 3.95 × 10−7, 3.13 × 10−7, and 2.35 × 10−7 mm3 N−1 m−1, respectively, which decrease with the increase of nano-CeO2 mass fraction. The wear mechanism is primary adhesive wear and oxidation wear, accompanied by slight abrasive wear, and the addition of nano-CeO2 is the main factor that is enhancing wear resistance.


I N 1941, Kveimi published a report on a "new and specific cutaneous reaction in Boeck's sarcoid." He observed that following the intracutaneous injection of a tissue suspension of sarcoid lymph nodes in 13 patients with active sarcoidosis, 12 developed a papule at the site of injection. Histologically, these papules resembled cutaneous sarcoidosis. No papule developed in patients with either tuberculosis or syphilis who were similarly tested. The test is not widely used, however, due to a number of inherent difficulties. The sarcoid tissue is not easy to obtain in quantity. The suspension cannot be standardized as to its potency, and the length of time needed to interpret the test tends to lessen its practical application. Further, subsequent investigators have questioned Kveim's opinion as to the test's specificity. It has been claimed that dead tubercle bacilli, 2 BCG vaccine, s > 4 normal spleen suspension, 6 ' 6 and leukemic lymph node suspension 7 ' 8 may give a response similar to the sarcoid-tissue suspension when injected into patients with sarcoidosis. Also, the test has occasionally been reported as positive in conditions other than sarcoidosis. 7-9 Nevertheless, interest in the test has been maintained by other reports 10-18 that tend to substantiate the usefulness of this delayed papular response in the diagnosis of sarcoidosis. The Kveim test has been employed extensively at the Cleve-land Clinic for the past three years. The present study is concerned with an evaluation of the test based upon the reactions in 88 patients. The results have proved to be of such consistent diagnostic and prognostic value as to prompt this preliminary report.


The college physics is one of core courses which are designated by the Ministry of Education for all specialties of science and technology at universities and colleges.Presently,there are some problems existing in the teaching of college physics at engineering and polytechnic universities.We thought over these problems and then gave some advice in order to improve the teaching quality.


Hyperpsectral image (HSI) provides abundant and detailed spectral information with limited spatial resolution. When a multispectral image (MSI) with higher spatial resolution of the same observed scene is available, this limitation on spatial resolution can be handled by applying fusion techniques. In this work, a novel HSI and MSI fusion approach using dictionary-based reconstruction is proposed. To incorporate more effective information for fusion, dual-source dictionary pair including a dictionary on low spatial resolution and a dictionary on high spatial resolution, is constructed using both HSI and MSI. Furthermore, to reduce the calculation cost, a localized strategy is applied instead of the global one. Finally, the fused result is reconstructed with dictionary using collaborative representation. Simulative experiments illustrate its outperformance over some state-of-the-art HSI and MSI fusion approaches.


The study in hand confirms that the basic strategy of MSW management is landfilling, not recycling. Drawing from the results of the dimensional multiple factor analysis of region-specific characteristics, the authors provide recommendations on selecting MSW landfill sites and their subsequent reclamation for the Konstantinovskiy District, Amur Region.


The effect of self-congruity and functional congruity on switching intention is one new issue that marketers are encountering. The purpose of this study is to review the relationship among four dimensions of self-congruity (actual, ideal, social and ideal social congruity) and functional congruity with switching intention. To deepen the understanding of customers' switching decision formation, the researchers attempted to develop a switching intention model, consisted of self-image dimensions (actual, ideal, social, and ideal social self-congruity) and functional congruity. At the end of this paper, some new issues are recommended for the future research in this field.


Background: Cutaneous squamous cell carcinoma (cSCC) is the malignant tumor derived from the keratinocytes of the epidermis. It is the second most common skin cancer in Indonesia. The infiltration of tumor-infiltrating lymphocytes (TILs) had been studied and related with the prognostic factor for many solid tumors. The research about TILs with Hematoxylin&Eosin staining for cSCC has not been studied until nowadays. Objective: This study was aimed to analyze the correlation of TILs with the tumor mass location and histological grading for cSCC. Methods: This is an analytical research with cross sectional approach using the slide and paraffine blocks from the patients diagnosed with cSCC with Hematoxylin&Eosin staining. The statistical analysis with Kruskal-Wallis method is used to analyze the correlation of intratumoral and stromal TILs with the tumor mass localation and histological grading of cSCC. Results: Based on the statistical analysis for 48 samples of the patients with cSCC, the p-value for the correlation of intratumoral TILs with the tumor mass location, stromal TILs with tumor mass location, and intratumoral TILs with the histological grading, are 0.824, 0.124, 0.058 (p>0.05). Meanwhile, the correlation of stromal TILs with the histological grading shows the p-value of 0.027 (p<0.05). Conclusion: Only the stromal TILs are closely related to the histological grading of cSCC.


In order to improving the designing efficiency and achieving automation of airfoil optimization designing, A method which combined the airfoil parametric modeling software, the CFD software with Isight platform was presented, it was used to optimize the airfoil to ameliorate its aerodynamic performance. During the process of optimization designing, first, we adopted the design of experiment (DOE) method to search the designing space, achieved the optimal initialization design. Then, we adopted Non-dominated Sorting Genetic Algorithm (NSGA-II) to optimize the airfoil, got the optimal airfoil aerodynamic solution. The optimized solution proved that the aerodynamic performance of the airfoil has been significantly improved, which shows the optimization designing method was reasonable and feasible.


The purpose of this study is to investigate the effects of two different types of vocabulary activities on Korean EFL learners' vocabulary learning and perceptions. The participants of the study were 30 Korean middle school students in Seoul, and they were divided into two groups (typography and web-based authoring). The former employed the word meaning and spelling image association technique and the latter used a multimedia vocabulary authoring tool for 42 target words. The major findings of the study are as follows: (1) Both the typography and the web-based vocabulary authoring groups showed significant improvement on the posttest of vocabulary test, which indicated the equal effectiveness of the two vocabulary activities; (2) with respect to different English proficiency levels, the low-level group showed much higher improvement of the mean difference between pre and post tests than the higher group; and (3) the participants' perceptions turned out to be more positive when they participated in creating English word spelling image than authoring multimedia vocabulary learning materials. The results suggest the beneficial effects of active student involvement in the vocabulary learning process. Pedagogical and practical suggestions are made on the effective teaching of English vocabulary in Korean classroom settings.


With increasingly more sophisticated phishing campaigns in recent years, phishing emails lure people using more legitimate-looking personal contexts. To tackle this problem, instead of traditional heuristics-based algorithms, more adaptive detection systems such as natural language processing (NLP)powered approaches are essential to understanding phishing text representations. Nevertheless, concerns surrounding the collection of phishing data that might cover confidential information hinder the effectiveness of model learning. We propose a decentralized phishing email detection framework called Federated Phish Bowl (FedPB) which facilitates collaborative phishing detection with privacy. In particular, we devise a knowledge-sharing mechanism with federated learning (FL). Using long short-term memory (LSTM) for phishing detection, the framework adapts by sharing a global word embedding matrix across the clients, with each client running its local model with Non-IID data. We collected the most recent phishing samples to study the effectiveness of the proposed method using different client numbers and data distributions. The results show that FedPB can attain a competitive performance with a centralized phishing detector, with generality to various cases of FL retaining a prediction accuracy of 83%.


The threshold enhancement of the cross section for the excitation of the symmetric stretching mode of CO2 by electron impact is described using a virtual-state model based on the projection-operator formalism of Feshbach. The analysis shows that the experimental data for the near-threshold (0, 0, 0) to (1, 0, 0) vibrational excitation cross section (Kochem et al., 1985) and the low-energy total electron-CO2 scattering cross section (Ferch et al., 1981), as well as fixed-nuclei electron-CO2 scattering calculations (Morrison), are compatible with the existence of a virtual-state pole of the fixed-nuclei scattering matrix close to the origin of the complex momentum plane.


Recently many Supermarkets, Insurance companies, and similar products or service providers started giving loyalty cards to their consumers as a marketing strategy to retain their loyal customers, due to this reason a single customer holds several loyalty cards and the basic idea of retaining customers by issuing just a loyalty card has arrived in to a complex problem. Therefore, the objective of this research is to identify what other factors affect the customers buying behaviour even after obtaining a loyalty card, so that the marketers could focus on improving the findings on this research to retain their consumers within their business even though consumers have several loyalty cards. This study focused on fourteen factors affecting the buying behaviour of consumers who already have a loyalty card. A questionnaire was distributed randomly and 207 successful responses were coded and analysed using several statistical tests for their significance towards the goal of identifying what factors are prioritized the most by the consumers when selecting a good or service. The findings revealed that, Consumers who concern mostly about the budget prefer closer shops, low price products, free offers, and promotions and out of which male customers preferred buying free products and searching for discounts more than females. Consumers who like trendy and new products prefer to visit shops that show respect and friendliness on them and also concerns about the time factor. A customer with a single loyalty card prefer to move towards the shops where they spend less time during their transaction and where the needed items can be easily located provided that the other factors are similar. More generally a customer gives the priority to visit the shops that give many rewards for loyal customers, rather than shopping from a place where just a loyalty card was given. However, Company being famous, started issuing the loyalty card first or attendants concern on the consumers was not affected in a different manner. Finally card holders showed high interest on having discount on vegetables/fruits and grocery items compared to beverage, fish/meet or bath-ware. Keywords— Loyalty cards, Customer loyalty, Customer satisfaction, Customer buying behaviour, CRM.


This research emphasized the use of financial rather than production or marketing variables as a mechanism for forming and analyzing strategic groups. Cluster analysis of computer industry firms in 1977 and 1980 indicated the different financial strategies pursued affected performance and should be incorporated in future studies of strategic groups.


This work shows that volatile signals, including methyl jasmonate and methyl salicylate, emitted by UV-irradiated plants can cause an increase in homologous recombination in nearby, nonirradiated bystander plants. Emission of these signals is triggered by the formation of necrotic lesions and depends on NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 function. We have previously shown that local exposure of plants to stress results in a systemic increase in genome instability. Here, we show that UV-C–irradiated plants produce a volatile signal that triggers an increase in genome instability in neighboring nonirradiated Arabidopsis thaliana plants. This volatile signal is interspecific, as UV-C–irradiated Arabidopsis plants transmit genome destabilization to naive tobacco (Nicotiana tabacum) plants and vice versa. We report that plants exposed to the volatile hormones methyl salicylate (MeSA) or methyl jasmonate (MeJA) exhibit a similar level of genome destabilization as UV-C–irradiated plants. We also found that irradiated Arabidopsis plants produce MeSA and MeJA. The analysis of mutants impaired in the synthesis and/or response to salicylic acid (SA) and/or jasmonic acid showed that at least one other volatile compound besides MeSA and MeJA can communicate interplant genome instability. The NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 (npr1) mutant, defective in SA signaling, is impaired in both the production and the perception of the volatile signals, demonstrating a key role for NPR1 as a central regulator of genome stability. Finally, various forms of stress resulting in the formation of necrotic lesions also generate a volatile signal that leads to genomic instability.


The U.S. government needs to do a better job of putting into strategic context its plans for new nuclear weapons, says a panel convened by the American Association for the Advancement of Science, which publishes Science . The main points of a new report by the panel were disclosed in February (


This chapter the proposed algorithm named Advancedblue is simulated in wireless network using NS2 simulator. Wireless network is quite different from wired network. The nodes have no wired links to other nodes and base stations, so any barrier that is between the sender and the receiver could influence the transmission power and bring packet loss. In this chapter the proposed algorithm is compared with the existing DropTail AQM and graphs are plotted with respect to throughput and packet loss.


In this Response to 'Federalism, Regulatory Lags, and the Political Economy of Energy Production,' Professor David Spence's first-to-market attempt to situate the highly charged political controversies surrounding hydraulic fracturing ("fracking") in the frame of federalism theory, I argue that the question of whether states or the federal government should regulate fracking has already been answered, and that but for outdated and underjustified exemptions to existing environmental statutes, fracking is already under the jurisdiction of federal regulators. In addition, I add to Professor Spence's attempt to match fracking's environmental impacts to the proper scale of governance in three ways. First, I examine several rationales commonly used to justify decentralization, rather than federalization, of environmental law, and find that they do not weigh in favor of exclusive state authority over fracking. Second, I argue that given the fast-paced growth in drilling activity across the country, fracking's environmental impacts should be analyzed with regard to their cumulative effects. When so viewed, it is clear that fracking gives rise to interstate, and even national, problems that must be addressed accordingly. Third, I argue that widespread impacts on rural America weigh in favor of federal regulation. In conclusion, I suggest that fracking's federalism choice question is an important one, and that the theoretical approach can help inform the political and regulatory process.


Inductance is an important parameter of PMSM due to its direct impact on the dynamic performance, especially on the precise control of the system. In this paper, an improved calculation method for the incremental inductance of motor winding is adopted, and a data processing technique is presented. Nonlinear incremental inductance of the motor winding was tested with the dynamic hysteresis loop method. The validity of the parameters FEM simulation results was confirmed by the measuring method. Accordingly, a mathematical model of nonlinear incremental inductance of SPMSM was built which provides a practical gist to determine uncertainty range of inductance parameter.


OBJECTIVE: To assess whether AFL at diagnosis of labour is an independent predictor of dystocia and CS. STUDY DESIGN: A prospective cohort study of 905 SSCNT attending the National Maternity Hospital over 9 months. Standard management of labour (Active Management of Labour) was applied including amniotomy at the time of diagnosis of labour. AFL was measured in all women using a point of care device (LMU061 ObstetCare, Sweden). Dystocia in the first stage was defined as the need for oxytocin when cervical dilatation was less than 1cm/hr over 2 hours and in the second stage by poor descent over 1 hour. A standard oxytocin regimen was used with a maximum dose of 30mu/ min. Standard statistical analysis included ANOVA and Pearson's correlation. Multivariate binary logistic regression models included all variables that were significant in univariate analysis. RESULTS: AFLwas normally distributed and did not correlate with age, BMI or gestation. Unsupervised decision tree analysis demonstrated that AFL could be divided into 3 groups <5(n=118), 5-10(n=707) and >10(n=80). Increasing AFL was associated with higher total oxytocin dose (p=0.001), dystocia (p=0.005) and CS (p<0.001). Multivariate regression analysis demonstrated that women with AFL>5 (OR=1.6, 95%CI 1.06-2.39) and AFL>10(OR=1.72, 95%CI 1.01-2.93) were independent predictors of dystocia. AFL>5 did not predict CS however multivariate analysis confirmed AFL>10 was an independent predictor of CS(OR=3.35, 95%CI 1.73-6.46). AFL>5 has a sensitivity of 89% in predicting dystocia and a sensitivity of 93% in predicting CS with a 97% negative predictive value. AFL>10 is highly specific but lacks sensitivity for CS. CONCLUSION: AFL at diagnosis of labour in SSCNT is an independent predictor of dystocia and CS. These data suggest that women with AFL 5-10 who are at risk of dystocia can be corrected with the Active Management of Labour protocol. (Table presented). Database: EMBASE 20.

Among 62 women with lactate levels >5.0 mmol/L, 67.7 % of women (n = 42) had spontaneous onset of labor within 24 h and 83.87 % women of (n = 52) within 48 h. Conclusion: A lactate level >5.0 mmol/L is significantly associated with the spontaneous onset of labor within 24 and 48 h in suspected cases of PROM. © 2013 Federation of Obstetric & Gynecological Societies of India.


An improved fluid urea-containing fertilizer composi tion is disclosed; the composition is essentially com prised of an aqueous solution of urea, ammonium ni trate, N-(n-butyl)thiophosphoric triamide (NBPT), di cyandiamide (DCD), and may optionally also contain a clay as a suspending agent. The fluid fertilizer composi tion can be applied to a field crop in a single application and will nevertheless supply sufficient nitrogen to the plants throughout their growth and maturing cycles. As a result, the improved composition increases the nitro gen uptake efficiency of plants, enhances crop yields, and minimizes the loss of nitrogen from the soil. The NBPT is incorporated into the fluid fertilizer com position by blending a concentrated solution of N-(nbutyl)thiophosphoric triamide in a solvent selected from the group consisting of liquid amides such as an N-alkyl pyrrolidone directly with an aqueous solution of urea and ammonium nitrate, optionally also contain ing a suspending agent and commonly referred to in the fertilizer trade as UAN; the DCD may be added to the UAN fluid as a solid, a suspension, or in dissolved form along with the NBPT. . .

This study compared the results of reflex modification (RM)—an objective technique for assessing brainstem sensorineural processing—with those of auditory brainstem response (ABR) for a group of high‐risk infants at comparable postconceptional ages. For the RM procedure, an eyeblink‐eliciting tap to the glabella was presented either alone or accompanied by a brief 90dB SPL tone. 37 high‐risk infants were tested with both RM and ABR at a mean postconceptional age of 37·3 weeks. Seven had an increased brainstem conduction time ('failed ABR') and eight did not exhibit significant reflex augmentation ('failed RM'), seven of whom also failed the ABR. These data provide evidence that sensory stimuli which affect the neural mechanisms responsible for the organization of the startle response and auditory processing share essential neural components.


In present research, we discuss some new f-divergence measures that call t-symmetric divergence measure and integral divergence measure, here we established convexity and some inequalities that connect these f-divergence to the classical introduced by Csiszar.


Abstract In situ gamma-ray measurements of four igneous rocks were taken in the Opava Mountains (Eastern Sudetes, Poland). The activity of naturally occurring radionuclides was measured using a portable GX3020 gamma-ray spectrometry workstation. The activity concentrations of 40K varied from 914 ± 17 Bqkg-1 (gneiss, Kamienna Góra) to 2019 ± 37 Bqkg-1 (weathered granite, Sławniowice), while those of 232Th from 7.5 ± 0.6 Bqkg-1 (weathered granite, Sławniowice) to 68 ± 0.9 Bqkg-1 (migmatitic gneiss, Nadziejów). The activities associated with 238U decay series ranged from 10 ± 0.4 Bqkg-1 (weathered granite, Sławniowice) to 62 ± 1.6 Bqkg-1 (gneiss, Kamienna Góra). The results will be used in compiling Radiological Atlas of the Sudetes


We report ab initio calculations of the structural, electronic, and magnetic properties of a graphene monolayer substitutionally doped with $\text{Co}\text{ }({\text{Co}}_{sub})$ atoms. These calculations are done within density-functional theory using the generalized gradient approximation. We focus in Co because among traditional ferromagnetic elements (Fe, Co, and Ni), only ${\text{Co}}_{sub}$ atoms induce spin polarization in graphene. Our results show the complex magnetism of Co substitutional impurities in graphene, which is mapped into simple models such as the $\ensuremath{\pi}$-vacancy and Heisenberg model. The links established in our work can be used to bring into contact the engineering of nanostructures with the results of $\ensuremath{\pi}$ models in defective graphene. In principle, the structures considered here can be fabricated using electron irradiation to create defects and depositing Co at the same time.


In sport activities and rehabilitation it is of great benefit to provide an autonomous and individual assessment system of motor activity. Providing quantitive data about the movement is not only valid for characterising the courses of training processes, it will also help the athlete to improve the technique or to enhance learning in motor rehabilitation. In this regard, significant features are required to monitor and score the movement-pattern. We analyzed different rowing parameters including grip pull out, grip force, slinding seat position and foot-rest force to derive relevant rowing features. An indoor rower was used to record several movement parameters of elite and novice athletes. Different features were extracted for each rowing parameter by assessing the difference of each feature value on elite and novice athletes. The most relevant features as well as rowing parameters were selected based on the signal-to-noise-ratio ranking. The efficiency of Naive Bayes classifier to differentiate the rowing activity between elite and novice athletes was investigated. According to the results five features are sufficient to achieve a high classification rate of 100%. Using the proposed feature set a grading system was introduced enabling to rank and score the quality related to motor activity in rowing.


The spurious free dynamic range (SFDR) of a direct-detection RF/photonic link is restricted by nonlinearity of the optical intensity modulation. We report a compact quantum well Mach–Zehnder (MZ) optical intensity modulator with enhanced linearity. The MZ modulator's linearity is improved by canceling the nonlinear distortions from the MZ interferometer and the optical phase modulation. The compact modulator is less than 4 mm long and has a Vπ of ∼5.5 volt. In an RF photonic link, the modulator helped to achieve an SFDR of 117 dB·Hz2/3  at 1 GHz with 1.4 mA photodetector photocurrent. A down-conversion RF photonic link using this modulator demonstrated an RF-to-IF SFDR of 108.1 dB·Hz2/3.


The period from the middle of the fifteenth century to the middle of the sixteenth century marks a transition in Jewish intellectual history in the Italian Renaissance characterized by the decline of Jewish rationalism and the rise of kabbalah. This process reached its culmination with the printing of Sefer ha-Zohar in 1558–59, an event accompanied by heated controversy on many fronts. During these years we find those thinkers who unambiguously profess their allegiance to one camp or the other, but we also find many whose allegiance is at least superficially ambivalent.

Finger veins based biometrics, as a new approach to personal identification, has received much attention in recent years. The methods based on low level feature, for instance the gray, texture of finger vein, are the mainstream, but they are usually faced with many challenges, such as sensitivity to noise and low local consistency. In fact, finger vein recognition based on high level feature representation has been proved to be a promising way to effectively overcome the above limitations and improve the system performance. Thus, in this paper, we present a novel identification framework, which utilizes superpixel-based features (SPFs) of finger vein for high level feature representation. When comparing two finger veins, the features of each pixel are firstly extracted as base attributes by traditional way. Then, after superpixel over-segmentation, the SPF of each finger vein can be obtained based on its base attributes by some statistical techniques. Lastly, a weighted spatial pyramid matching (WSPM) scheme is utilized to implement matching. Our experiments have yielded some very good results evidenced by an EER of 0.0147 on the benchmark database PolyU.

Currently there is no cure for HIV/AIDS. The only way to deter progression of this disease is through regular prophylactic and curative treatment regimens. Thus, it is critical that patients are compliant with their outpatient medical appointments. Despite this, high rates of noncompliance have been reported among patients with HIV/AIDS. In addition, little attention has been directed toward establishing causal factors of this noncompliance. The present study represents one of the first efforts to elucidate psychosocial, illness, and demographic factors associated with compliance with outpatient, HIV-specific treatments. The results of this study indicate noncompliance with medical appointments is a significant problem. One in five patients dropped out of the clinic before completing their intake assessment and 35% of scheduled medical appointments were not attended. Patients with lower levels of social support and males were more likely to drop out of the clinic system before seeing a physician. Additionally, CD4 counts at clinic intake, heterosexual orientation, African-American race, and female gender were significantly associated with non-attendance of scheduled appointments during the year following patients' clinic intake, with CD4 counts and heterosexual orientation accounting for the greatest amount of variance in patients' nonattendance. Although emotional distress was not associated with clinic attendance, significantly elevated levels of anxiety and depression were found. Practical implications of these findings are discussed.


This paper examines the involvement of the United States in the Russia-Ukraine war. One of the main topics of study in Cold War studies is how the United States interacted with and intervened in various domestic affairs of nations in different regions of the world between the 1950s and the 1970s.  States interact with one another in particular through international relations. Realists view international politics as fundamentally a contest between superpowers over dominance and security. During the cold war, Russia and Ukraine were united in a federated state, the Soviet Union. And in 2022, the conflict between Russia and U kraine is heating up again, and the United States will be involved here. However, this study focuses on the involvement of the United States in the Russo-Ukrainian war, which is analyzed with one of the main theories in international relations, realism. Realism theory focuses on the potential for conflict between state actors, particularly relevant to the conflict between Russia and Ukraine. This research employs a qualitative methodology with a literature review, in which the author gathers data pertinent to the subject under consideration. The result of this research is the involvement of the United States in the war between Russia and Ukraine is part of their tactics to maintain their hegemony as the only superpower in the post-cold war world.

van der Waals (vdW) crystals consist of individual atomic planes coupled by vdW interaction, similar to graphene monolayers in bulk graphite. We investigated van der Waals heterostructures assembled from atomically thin layers of graphene and hexagonal boron nitride (hBN). We launched, detected and imaged plasmonic, phonon polaritonic and hybrid plasmon-phonon polariton waves in a setting of an antenna based nano-infrared apparatus. Hyperbolic phonon polaritons in hBN enabled sub-diffractional focusing in infrared frequencies. Because electronic, plasmonic and phonon polaritonic properties in van der Waals heterstructures are intertwined, gate voltage and/or details of layer assembly enable efficient control of nano-photonic effects.

Introduction The fast moving global economy has necessitated that organizations learn and adapt quickly to the increasing pace of change, and turbulence of the environment. Organizations today require more cross-functional working, more cooperation between areas, and more integration in their processes if they are to meet the customers' needs. Such co-operation can be achieved only when organizations reorient themselves towards people-based systems that focus on motivation, involvement, development and empowerment. It is a fact that employees are the most strategic resource of any organization. As contrast to technologies, product and processes, the knowledge, skills and abilities of the employees cannot be imitated by their competitors. As such, retaining its most valuable assets while utilizing the employees' individual capacity to improve and enhance organizational performance is a daunting task for any organization. Achieving performance in these new circumstances requires that employees take and exercise much greater responsibility. Thus, empowerment is a strategy, a philosophy, a concept of giving employees responsibility, power, and autonomy to make decisions about their jobs. It is a process which has evolved in response to a trend towards a greater responsibility and involvement amongst employees in running their organizations. This trend has emerged as most organizations have realized the importance of people involvement and recognized the capacity of their human resources to improve and enhance business performance (Pattanayak, 2001:221). Bowen and Lawler (1992:32) defined empowerment as "sharing with front-line employees four organization ingredients: [the first being] information about the organization's performance.... [another is] knowledge that enables employees to understand and contribute to organizational performance". The other two ingredients they note were: "rewards based on the organization's performance [and] power to make decisions that influence organizational direction and performance. Later the authors concluded that "empowerment exists when companies implement practices that redistribute power, knowledge, and rewards throughout the organization. ..." (Bowen & Lawler, 1995:73-74). The authors further went on to note that "if any of the four elements is zero, nothing happens to redistribute that ingredient, and empowerment will be zero". Spreitzer (1995:1442) defined psychological empowerment "as a motivational construct manifested in four cognitions: meaning, competence, self-determination, and impact. Together, these four cognitions reflect an active, rather than a passive, orientation toward a work role." Spreitzer noted that "The four dimensions are argued to combine additively to create an overall construct of psychological empowerment. In other words, the lack of any single dimension will deflate, though not completely eliminate, the overall degree of felt empowerment." This additive construct is distinct from Bowen and Lawler's (1995) construct noted above which is multiplicative, indicating that the absence of any one of their four elements (power, information, knowledge, and rewards) will completely eliminate empowerment. From the above definitions, it may be discerned that in order to achieve empowerment of employees, managers must be sure that employees at the lowest hierarchical levels have the right mix of information (about process, quality, customer feedback and events), knowledge (of the work, the business and the total work system), power (to act and make decisions about the aspects of work) and rewards (tied to business results and growth in capability and contribution), to work autonomously or independently of management control and direction (Lawler, 1992; 1994; Lawler et al., 1989). Thus, the competitiveness of an organisation depends to a large extent on the presence of the above four elements: Information-sharing/open communication, knowledge development, autonomy, and rewards. …


We study the nascent setting of online computation with imperfect advice, in which the online algorithm is enhanced by some prediction encoded in the form of a possibly erroneous binary string. The algorithm is oblivious to the advice error, but defines a desired tolerance, namely an upper bound on the number of erroneous advice bits it can tolerate. This is a model that generalizes the untrusted advice model [Angelopoulos et al. ITCS 2020], in which the performance of the algorithm is only evaluated at the extreme values of error (namely, if the advice has either no errors, or if it is generated adversarially). In this work, we establish connections between games with a lying responder, also known as R\'enyi-Ulam games, and the design and analysis of online algorithms with imperfect advice. Specifically, we demonstrate how to obtain upper and lower bounds on the competitive ratio for well-studied online problems such as time-series search, online bidding, and fractional knapsack. Our techniques provide the first lower bounds for online problems in this model. We also highlight and exploit connections between competitive analysis with imperfect advice and fault-tolerance in multiprocessor systems. Last, we show how to waive the dependence on the tolerance parameter, by means of resource augmentation and robustification.


In this paper, the effect of heat treatment processing on magnetic properties of Fe-3.5Si soft magnetic composite has been investigated. The thermal treatment improved the magnetic properties of Fe-3.5Si SMC materials. With the treatment temperature increasing, the permeability and eddy loss of the composites increase and the core loss and hysteresis loss decrease. The magnetic properties would be deteriorated at too high temperature. Annealed temperature at 750°C for 60min, the Fe-3.5Si soft magnetic composite has the optimum overall magnetic properties.


Witch-hunting did not disappear from the repertoire of the bourgeoisie with the abolition of slavery. On the contrary, the global expansion of capitalism through colonization and Christianization ensured that this persecution would be planted in the body of colonized societies, and, in time, would be carried out by the subjugated communities in their own name and against their own members. (Silvia Federici, Caliban and the Witch, Women, The Body and Primitive Accumulation) Discussing witch-hunting as a global phenomenon, at the end of Caliban and the Witch (2004), and commenting on the witch-hunts that have taken place in Africa and other parts of the world in the 1980s and 1990s, I expressed my concern that these persecutions were rarely reported in Europe and the U.S. Today, the literature on the return of witch-hunting on the world scene has grown and so have media reports of witch-killings, coming not only from Africa, but India, Latin America, Papua New Guinea. Yet, with few exceptions, (2) social justice movements and even feminist organizations continue to be silent on this matter, although the victims are predominantly women. By witch-hunting I refer to the recurrence of punitive expeditions by young male vigilantes or self-appointed witch-finders, often leading to the murder of the accused and the confiscation of their properties. Especially in Africa, this has become a serious problem over the last two decades continuing to this day. Just in Kenya, eleven people, eight women and three men, were murdered in May in the Southwestern province of Kisii, accused of witchcraft (USA Africa Dialogue 5/24/08). Studied mostly by anthropologists, witchcraft accusations and killings should concern all feminists, North and South. For in addition to inflicting an unspeakable suffering on those accused, and perpetrating a misogynous ideology that degrades all women, they have devastating consequences for the communities affected, especially the younger generations. They are also emblematic examples of the effects of economic globalization on women, further demonstrating that it contributes to the escalation of male violence against them. In what follows, I discuss the witch-hunts in Africa, examining their motivations and suggesting some initiatives that feminists can take to put an end to these persecutions. My argument is that these witch-hunts must be understood in the context of the deep crisis in the process of social reproduction that the liberalization and globalization of African economies have produced, as they have undermined local economies, devalued women's social position, and generated intense conflicts between young and old, women and men, over the use of crucial economic resources starting with land. In this sense, I see the present witch-hunts on a continuum with such phenomena as the dowry murders and the return of sati in India, and the killings of hundreds of women in the Mexican towns at the border with the U.S., victims of rapists or snuff/porno producers. For, in different ways, they too are an expression of the effects of "integration" into the global economy, and men's readiness to vent on women their economic frustrations and even sacrifice their lives to keep abreast of advancing capitalist relations. These witch-hunts are also on a continuum with the worldwide return of "the supernatural" in political discourse and popular practice (e.g. "satanic cults" in Europe and the U.S.), a phenomenon that can be attributed to the proliferation of fundamentalist religious sects but, significantly, has emerged in conjunction with the globalization of economic life. My analysis concludes that while mobilizing against these egregious violations of women's rights, feminists should put on trial the agencies that have created the material and social conditions that have made them possible. These include the African governments who do not intervene to prevent the killings or punish them; the World Bank, the International Monetary Find and their international supporters, whose economic policies have destroyed local economies, fueling a war of all against all. …

Due to increase in demand of green energy, Hybrid PV system is no longer an auxiliary power source but have become a part of electricity generation system. In case of grid connected PV System, it is desirable that system should supply constant real power to grid at high power factor, even when there is variation of local load supplied by PV system. In this paper control mechanism is proposed in which constant real power is injected into the grid taking load variation into account. Battery storage system is employed and used in charging mode simulate hybrid system and injection of harmonics in PV current. Power flow is controlled by adjusting phase shift of inverter to change its power factor. Constant power injection into the grid for different cases of load variation is studied and its effect on power factor at different buses is considered and scheme is proposed which addresses issues faced by this system.


Due to policy boundaries, the results and conclusions of my thesis cannot be disclosed in this paper. Instead this paper will provide background information about myasthenia gravis (MG) and the role of immunoglobulin G (IgG) antibodies in autoimmune MG. Additionally, previous literature will be discussed to elucidate the aim and relevance of my internship project. During the internship, total IgG and IgG subclass (IgG1, IgG2, IgG3, and IgG4) concentrations were evaluated in serum of anti-muscle specific kinase antibody positive MG (MuSK-MG), anti-acetylcholine receptor antibody positive MG (AChR-MG) patients and compared with the total IgG and IgG subclass levels in healthy control serum.


Given the growing demand among consumers of the international market for propolis, it is important to review the compliance of national documentation with international, particularly the leading countries in the production and processing of this product. Integration and adaptation of national legislation to the norms of the world community legislation also requires revision of approaches to the quality and safety of propolis. Therefore, the purpose of the study was to analyse the current international and national regulatory legal acts of the leading countries of the world, which play a key role in the international market for the production and sale of propolis in terms of safety and quality of propolis. Authors used the Torraco method to analyse and synthesise scientific and regulatory data; the Springer scientific and metric database and the Google Scholar search. The materials included regulatory documents of Ukraine, EU, Brazil, Argentina, Poland, Mexico, East African region. It was established that the criteria for assessing the quality of propolis in international regulatory and technical documentation are organoleptic (appearance, consistency, colour, smell, taste), physicochemical (dry matter, total ash content, wax, resin) microbiological (yeast, moulds, Escherichia coli, Staphylococcus, Candida albicans, Paenibacillus, Salmonella) indicators of biological activity (flavonoids, oxidation, phenols, antioxidant activity, ethanol-soluble resins) and contamination (heavy metals, pesticide and antibiotic residues, radionuclides). The study revealed the non-compliance of the current regulatory document in Ukraine with the requirements of international regulations, namely in terms of: phenol content, ethanol and water-soluble resins, dry matter; total ash content; antioxidant activity; colony-forming units. It was determined that in Ukraine propolis is not divided into categories depending on wax impurities; the ambient temperature is not accounted for when determining the consistency index; botanical origin and methods of its selection are also not considered when assessing organoleptic properties. The approach for regulating the propolis market in Ukraine is substantiated as such that will contribute to the formation of added value for raw propolis when grouped by purpose and method of production and processing. The materials of the article are of practical value for the formation of new and harmonization of existing normative and technical regulations on the quality of propolis and can be applied by the working party on beekeeping development under the Ministry of Agrarian Policy of Ukraine


Business registers are the foundation upon which all business statistics are compiled. In addition to providing sampling and weighting frames, they are a rich source of information on national and regional economic and industrial structures. The comprehensive coverage of business registers is of particular relevance in the context of tourism, which is a fragmented sector dispersed across a variety of industries. This paper presents a profile of enterprise demography and employment for the tourism industries in Ireland at county level, which corresponds with level 4 of the European Union spatial classification 'NUTS'. New metrics, entitled 'Tourism Dependency Ratios' are derived and mapped. These ratios illustrate how the tourism supply side can be analysed and understood from a spatial perspective. A full-time equivalent (FTE) estimate of employment in the tourism industries is also provided; this is especially important, as it provides a more stable and comparable measure of employment over time.

In the past, Third World places and peoples have been promoted largely by First World tourism agents who relied heavily on stereotyped images from a colonial past, consequently depriving local communities of opportunities and the right to define their own public identity. This study examines how members of three socio-demographic groupings in a rural community in the Limpopo Province of South Africa would prefer to be presented, and the article argues that communities should have a say and control in this respect. Qualitative research which took socio-demographic variables such as age group, level of education and occupation into account was conducted in three rural Venda villages in the Limpopo Province which have been exposed to tourists. Most respondents preferred accurate representation of their traditional culture in promotional material, but significant differences between groups emerged, providing a fragmented picture, indicating that it is impossible to provide a general, representative portrayal of community perceptions and ways in which communities prefer to be promoted.


Policy makers concerned with the social and economic development of less developed countries (LDCs) strongly desire to know whether mortality affects fertility and, if so, how much. Through their approaches and skills, demographers have made significant contributions toward resolving these concerns by developing a persuasive theory of demographic transition. This theory, and the assembled evidence, justify the emphasis development planners have placed on the need to control birth rates so that rapid population growth does not nullify the efforts of national governments to provide a reasonable measure of welfare for all their people. Consequently, for the past 20 years family planning programs have absorbed an important fraction of the effort and expenditures authorized by planning commissions and ministries of health and/or family planning.


Congenital epulis of the neonate (CE) or congenital gingival granular cell tumor (CGCT) is a rare, benign, mostly single tumor. This arises from gingival mucosa, most commonly from maxillary alveolar ridge, with predominance in females. The histogenesis of the lesion remains unclear. The present report describes a case of congenital epulis in the maxillary alveolar ridge. This lesion was causing feeding difficulties and was excised under general anaesthesia. InTRoduCTIon Congenital Epulis is a rare, benign, soft tissue gingival lesion [1,2,3]. Neumann described the first case of CE in 1871, hence it is also known as Neumann's tumor [1,4,5]. The word 'Epulis' is derived from a Greek word, meaning 'on the gum' or gum boil. CE commonly arises from the future site of the maxillary canine or lateral incisors [6] of newborn, and is usually not associated with any other congenital malformations [4,5]. CE has a female predilection with 8-10:1 ratio [1,4,5,7]. Zuker and Buenecha in a review (1993) described only 167 reported cases in the literature [2]. To date, there are about 200 reported cases in literature [5]. This report documents the presentation and management of a congenital granular cell tumour of the left maxillary alveolar ridge, found in a female newborn, and treated with prompt surgical excision. We did a review of Indian literature and were able to document 23 reported cases of CE in India, indicating its predominant Caucasian distribution and relative rarity in the Indian Subcontinent. CASe RepoRT A term female neonate presented at 4 hours of life to our center for evaluation of a firm pedunculated mass protruding from mouth [Table/Fig-1]. The neonate was born to a G2 P1 L1 unregistered mother by normal vaginal delivery with an unremarkable antenatal history. The birth weight was 2700 grams. Maternal & paternal medical histories were non-contributory. The mass was attached to the gingiva of the left maxilla, measuring 4.0 x 2.0 x 4.0 cm, was of the same colour as the oral mucosa, smooth-surfaced and pedunculated. On palpation, it was firm, not compressible or reducible, and non-tender. The mass hindered breast-feeding, but did not cause airway obstruction or respiratory distress. No other structural deformities were noted. The neonate required no mechanical respiratory support, since it did not obstruct the airway. Postnatal MR imaging on day 2 of life revealed a lobulated, well-defined mass arising from the maxillary ridge without extension into the nasal airway, soft palate, floor of the mouth, mouth, nose or cranium [Table/Fig-2]. The unerupted upper teeth appeared normal. The history, clinical features & MRI of the lesion suggested its benign nature.

Abstract : A speed control for a direct current motor. A reference frequency is provided to a programmable counter which provides an output divided by a predetermined number. The output from the programmable counter is one input to a phase comparator whose output drives a direct current motor through a power amplifier. A tachometer associated with said direct current motor provides a second input to said phase comparator. A trans-resistance amplifier provides negative feedback to said power amplifier and determines the overall gain. (Author)


The instinct of life and the fear of death, the last but a manifestation of the first, occupy and have always occupied a supreme place in human consciousness. To mitigate the pain inspired by fear of death metaphysicians have goaded their wits since the beginnings of history, while believers in various religions, by affirming the existence of man bcyond the tomb, have either diminished or increased the dread of dissolution, depending on whether or not the dogma was believed and whether happiness or the reverse was predicted. This article is a consideration of the origin and nature of the morbid exaggeration of the natural, instinctive fear of death shown by some individuals and which, in some cases, amounts to a dominating tyrannical besetment, or to a monomaniacal obsession. This morbid dread of death is a psycopathic condition and concerns chiefly the neurologist and alienist, but any physician suddenly may


One of the key drivers that characterize both the processes of reorganization of the higher education model of education and the need for it is the process of globalization, affecting almost all aspects of modern life, and the informatization of the educational process associated with the rapid development of innovative computer technologies. At the same time, the main goal of the information based educational environment should be to ensure the transition of education to a new level of quality, i.e., to a state corresponding to the development of the information society and the associated need of specialists of appropriate skill levels. Currently, there is an active search for new forms and methods of teaching, which makes it possible to talk about the transition of education from a directive model to an interactive, learner's personality-oriented, more productive, one. The article deals with the possibility of using innovative teaching methods in preparing technical university students. Also, advantages and disadvantages of traditional and innovative teaching methods are described, through the development, application and implementation of innovative technologies.


specimens likely account for the majority of positive cultures. In these cases, no antimicrobial therapy has been administered, and the rate of subsequent device infection has been no greater than expected. Thus, cultures should not be obtained routinely, because if positive, they could be misinterpreted as being clinically significant and lead to the inappropriate administration of antimicrobials, or worse, removal of the newly implanted device.

Lithium‐sulfur (Li‐S) batteries are a promising candidate technology for high‐energy rechargeable batteries due to their advantages of abundant materials and inherently high energy. However, the practical applications of Li‐S batteries are challenged by several obstacles, including the low sulfur utilization and poor lifespan, which are partly attributed to the shuttle of lithium polysulfides and lithium dendrite growth during cycling.[1] The shuttling of polysulfide ions between the electrodes in a Li‐S battery is a major technical issue triggering the self‐discharge and limiting the cycle life.[2] A stable lithium anode is essential for maintaining the good cycle stability of Li‐S batteries in practical applications.[3] To address these lithium related issues, various carbon materials, including graphite and graphene, have been investigated as suitable lithium hosts to use as anode materials for Li‐S batteries.[4] In this study, prelithiated graphite and graphene‐based anode materials are obtained by galvanostatic charging method to improve the performance of Li‐S batteries and compare the electrochemical properties especially in terms of capacity retention and rate capability. According to the results, graphene showed better performance due to its high lithium storage capacity and fast lithium‐ion diffusion rate. Inductively Coupled Plasma Emission Spectrometer (ICP‐OES) results showed that the Li+ content of the graphite, graphite/graphene, and graphene electrodes measured as 26.5, 33.2, and 45.6 wt%, respectively after the lithiation process. 1 Ah pouch cell was assembled with prelithiated graphene anode showing an energy density of about 400 Wh kg−1 in the first cycle and protected its specific capacity of 60 % after 100 cycles in a liquid‐based Li‐S battery system.


The donor–acceptor codoping is an effective approach to tune the photoelectrochemical properties of TiO2. Here, we systematically investigate the effects of (I+N) codoping on the electronic structures and H2O splitting reactions of anatase TiO2 by using density functional theory. It is found that the codoping of the stable charge-compensated (I+N) donor–acceptor pair in anatase TiO2 not only can prevent the recombination of photogenerated electron–hole pairs but also can effectively reduce the band gap to 2.251 eV by forming an intermediate band within the band gap. The band edge alignment of (I+N) codoped TiO2 is desirable for H2O splitting, and the calculated optical absorption curve of (I+N) codoped TiO2 verifies that (I+N) codoping can significantly improve visible-light absorption. Moreover, we also calculate the chemical reaction pathways of H2 generation via H2O splitting on (I+N) codoped TiO2 surfaces by using the climbing nudged elastic band (cNEB) method and find that the (I+N) codoping in TiO2 ...


We consider a non-instantaneous system represented by a second order nonlinear differential equation in a Banach space E. We use the family of linear bounded operators introduced by Kozak, Darbo fixed point method and Kuratowski measure of noncompactness. A new set of sufficient conditions is formulated which guarantees the existence of the solution of the non-instantaneous system. An example is also discussed to illustrate the efficiency of the obtained results.


Introduction:
 Cell-based therapies for stroke remain under development and there is a lack of pre-clinical large animal data defining optimal dosing and delivery methods. Whereas safety and efficacy of intra-arterial (IA) mesenchymal stem cells (MSC) have been demonstrated in rodent models, large animal model are lacking, hampering advancement of the field and limiting mechanistic insights.

 Methods:
 An endovascular canine reversible Middle Cerebral Artery Occlusion (MCAO) model using a retractable platinum coil for 60-120 min was established. At 48-hour post-MCAO, allogeneic male canine MSCs (10-80 million) were delivered using a microcatheter in the ipsilateral upper cervical internal carotid artery of female canine subjects. Serial MRIs and neurological deficit scoring (NDS) were performed over 30 days. Animals were euthanized at15-30 d post-MCAO and brains were harvested for histology and molecular analyses.

 Results:
 There was a dose-dependent reduction of infarct volume on MRI associated with improved neurological scoring and corticospinal tract caliber on Diffusion Tensor Imaging over the range of 10, 20 and 40 million MSCs vs. PBS control. This dose-range was safe and did not result in worsening of stroke volume or behavioral outcomes. In contrast, 80 million IA MSCs led to a worsened neurological score immediately following the injection and an increase in the infarct volume at 4 days post injection.

 Conclusion:
 Together these findings establish a successful preclinical canine model of stroke in which dose-dependent efficacy of IA MSC therapy is demonstrated to reduce stroke size and augment DTI. These findings have important clinical implications in designing early-stage trials of IA delivery in humans.
