Carrier relaxation in phosphorus-implanted silicon wafers ${(10}^{16}{\mathrm{P}}^{+}/{\mathrm{cm}}^{2})$ annealed at different temperatures ranging from 350 to 1100 \ifmmode^\circ\else\textdegree\fi{}C is investigated by near-infrared ultrafast time-resolved reflectivity measurements. A kinetic model based on four couple differential equations describing the carrier density, electron, hole, and lattice temperatures is used to evaluate the expected changes in the time-resolved reflectivity. This model was used to fit the experimental data having the trap recombination time constant and the optical absorption coefficient as fitting parameters. Our measurements reveal a complicated recovery of the ion-implanted silicon samples to crystallinity following annealing with carrier lifetimes ranging from 1 psec for the nonimplanted sample and reaching \ensuremath{\sim}95 psec for the highest-annealed sample. Although this recovery directly effects the lifetime of the carriers, there are nontrivial mechanisms that activate recombination centers and traps throughout the annealing process, resulting in carrier lifetimes that are shorter than expected at higher annealing temperatures. Raman scattering data demonstrate the disorder and the recovery of ion-implanted silicon to its crystalline form, offering a direct comparison to the time resolved reflectivity data.


The aim of this work was to characterize the structural modifications of model beta-amyloid peptides and the lipid membrane upon binding. The first step of this thesis was to reproduce the random-coil to beta-sheet structural transition of bAP(25-35). It appeared that additional energy, brought by stirring or heating, acts as a catalyst of the structural transition. Also the presence of inhomogeneous aggregates of bAP(25-35) in the solution influences the CD spectra and thereby the analysis of the peptide secondary structure. This work points out the experimental factors that can strongly influence bAP(25-35) secondary structure and make biophysical studies difficult. In this study, an alpha-helical intermediate was observed for the first time in the random-coil to beta-sheet transition of bAP(25-35).
bAP(25-35) has no chromophore and the quantification of the peptide content was difficult, in particular under conditions of aggregation. Amyloid model peptides were therefore synthesized. The insertion of Trp either at position 24 or 32 of bAP(25-35) resulted in two analog peptides, WbAP(25-35) and bAP(25-35)_I32W. They form aggregates in aqueous buffers at micromolar peptide concentrations, similar to bAP(25-35). HFIP pretreatment homogenizes WbAP(25-35) solutions at physiological and acidic pH values. The aggregates of bAP(25-35)_I32W are small and no effect of HFIP pretreatment was observed. Aggregates with sizes ranging from 60 to 600 nm are measured with dynamic light scattering for the three pretreated peptides. Nevertheless fibril formation of the two analogs could not be observed with Thioflavin T fluorescence, in contrast to bAP(25-35). The presence of Trp in WbAP(25-35) and bAP(25-35)_I32W seems to hinder the binding of the fluorescent dye. Our work opens new possibilities in the design of amyloid model peptides that can facilitate structural and thermodynamic studies.
CD spectroscopy showed that the presence and position of Trp influences the secondary structure of the free and the lipid-bound amyloid model peptides. The lipid membrane favors the random-coil structure of bAP(25-35) and WbAP(25-35) at low peptide concentration. This shows the dual role of the membrane which can enhance beta-sheet content in the peptide structure at higher peptide concentrations. Thermodynamic parameters of the peptide-to-lipid binding could be determined at pH 4.0. In addition, we demonstrated with solid-state NMR that the insertion of the amyloid model peptides into the lipid membrane influences the fluidity of the lipid acyl chains. In contrast, the association of aggregated amyloid model peptides from the aqueous phase with the lipid membrane leads to the formation of an isotropic phase. This phenomenon is reported here for the first time and might be correlated with the toxicity of the amyloid peptide on the neuronal cells.
The NMR study of DMPG at high lipid content proved that DMPG is in a bilayer state at low and high salt content. At high ionic strength, the phase transition occurs at 24°C. At low ionic strength, two distinct bilayer phases are observed on the NMR spectra; they are characterized by a broad phase transition between 20 and 24°C. The results obtained at low lipid content and high ionic strength are similar to those at high lipid content: bilayer features are observed on the whole temperature range and the gel-to-liquid-crystal transition occurs at 23°C, as proved with DSC and NMR data. At low lipid content and low ionic strength, bilayer characteristics are also observed on the whole temperature range in the 2H-NMR spectra. In contrast, during the phase transition, an isotropic line is observed in the 31P-NMR spectra. Spectral fitting indicated that at low ionic strength, the phase transition is characterized by enhanced motions of the acyl chains and a change in the orientation of the phosphoglycerol headgroup. In addition, we observed thixotropy in all samples upon prolonged heating, independently of the lipid or salt content.


carnival in Latin America, the superhero, and so on), which is highly logical and coherent. The scholarly work is presented one at a time, described, and comparisons are drawn. But, no major conclusions are reached. They are but points on a map connected by masquerade. Their situatedness is not interrogated nor complicated by reference to their place in a wider territory or field. This has the advantage of being succinct with the frustration of being underdeveloped. Stylistically I found this book to be both carefully articulated and lacking. The author can write. The sentences are lucid and fluid. But, there are not enough of her own words in this book. She quotes primary and secondary sources extensively. This over-reliance on what others have said without interrogating their assertions takes from the flow and, ironically, masks meaning. An example of this can be found in her discussion of Zorro where she quotes Tom Morris's analysis of Batman/ Bruce Wayne without following it up with a fully realized connection to Zorro as Diego de la Vega's alter-ego (104). It seems to be there as illustration, but falls short of what I would expect of scholarly work. I read this book with my editor's hat firmly in place. Not because I chose to take this approach from the outset, but rather because the book elicited this response in me. I consider every completed academic book as an achievement in itself, but one that deserves careful consideration as to its place, function, and value. Conceptually, I want more from this book and would like to see the author's work develop. By that, I want to make reference to the conclusion where she signalled her conclusions as a scholar in the field that feels more ambitious and generative than what is realized in this book. She concludes that masquerade functions at a literal, intertextual, and symbolic level in the historical novel and that the historical novel can be read as masquerade masking other genres. I did not find this to have been fulfilled by the current study, however, if this is indicative of future work, it has considerable merit and should be pursued.


The objectives of social studies in Yugoslav elementary schools stem from the social, economic, and political forms of that nation's government (1). Because of its socialist-communist orientation, great emphasis is placed on the social studies as a "science of society," and all teaching is carried out within this conceptual framework. Consequently, work in this area must serve as a means to educate the children in the principles and practices of Marxist Leninism and must also provide the children with specific knowledge, skills, and abilities (2). With this dual purpose as a goal, the social studies curriculum in the elementary school has recently been revised in Yugoslavia. Under the old program, geography and history were separate subjects first taught in Grade 3. Nothing in the way of a social studies program was provided for pupils in Grades 1 and 2. The curriculum changes, which seek "to bring education closer to [socialist] life" (3), follow the recommendations of the special Commission for School Reform in its report, The Proposed System of Education in the Federal People's Republic of Yugoslavia and also the mandates of the General Law on Education in Yugoslavia, which was subsequently enacted. The curriculum now has been di-


The main objective of this theoretical framework is to clarify the theory of the operation of a bipolar hybrid stepper motor. By applying suitable synchronous phase voltages to its two independent coils, the motion of the motor's rotor can be ensured. The rotor's angular displacement can be determined without any feedback signal. This is one of the major advantages of this type of motor. In control engineering terms, this is The open-loop control approach.Therefore, the task is how preparing those suitable synchronous phase voltages to control rotor angular displacement. A driver consists of two components a decoding circuitry and an actuator, was designed to produce the required phase voltages. The decoder provides sequencing logic control signals to the actuator. The actuator, which is a dual H-bridge, will feed prescribed phases to the motor's coils.Derivation of a mathematical model for the motor itself results in a nonlinear state-coupled system. The derived model along with the motor's driver is implemented in Matlab/Simulink environment. By this stage, we reach the complete picture of the system under study.At the end, the system needs to be simulated. A general simulations for the obtained system has been presented and discussed. The obtained results showed the stepping behavior in the rotor's angular displacements. The open-loop control approach was able to control the size of those steps at a certain level of accuracy. Also, the ability of the driver of controlling the direction of rotation has proved.


employment, and the right to self-determination" (188). They want more support for childcare and the elderly and an end to harassment and violence against women. Her interviewees consistently reported that despite the challenges of the transition, Tunisia had a solid reform tradition rooted in gender equity, "and will end up finding its own path toward democracy and human rights for all Tunisians" (191). Honwana's conclusions sober the advocates of democracy and civil society. Youth created new democratic forms in civil society, but they have not been able to translate them into formal political power. Young Tunisians who played the central role in overthrowing the country's dictatorship simply "have not been integrated into political parties or taken an active role in formal politics" (192). Samir, a twenty-seven-year-old from the coastal city of Sousse, asserted that youth will overcome this: "The youth is the future and we will steer the development of our own society...Just give us time" (193). Honwana makes it clear that neither the traditional political parties nor those who emerged in the wake of the overthrow have spoken to the key concerns of youth: unemployment, social justice, and civil liberties. Instead, campaigns (and then governance) have centered on diversionary debates between secularism and Islamism, rather than the central challenge of neoliberal economic failures and establishing a climate where civil society could flourish. This is not unusual: as the eminent scholar of social movements, Lawrence Goodwyn, once reflected, the burden organic to the creation of large-scale democratic movements is that they need to stay accountable to the movement's mass base. Too often, he reflected, those who govern in the wake of overthrow take an imperial or condescending stance, rather than a relational one, to those youth or farmers or workers who made the overthrow possible. Governance often proves a hollow echo of the early, heady days of democratic promise. Honwana's work gives us a front-row seat to view these processes.

Cancer diagnosis and clinical outcome prediction are among the most important emerging applications of machine learning. In this paper we have used an approach by using support vector machine classifier to construct a model that is useful for the breast cancer survivability prediction. We have used both 5 cross and 10 cross validation of variable selection on input feature vectors and the performance measurement through bio-learning class performance while measuring AUC, specificity and sensitivity. The performance of the SVM is much better than the other machine learning classifier.


Based on Mettler-Toledo TGA thermogravimetric analyzer, a series of combustion experiments for two kinds of different coal samples as well as their blends were conducted. The effect of factors such as mixture ratio, heating rate on the combustion characteristics have been investigated. The result shows that ignition temperature of coal increases with the increasing heating rate. Under the different heating rate and mixture ratio, TG curves have basically the same trend. Ignition temperature curves show a small amount increase and irregular change trend and Rw curves show the overall trend at different heating rate and ratio. Introduction With the rapid development of utility industry in recent years in China, coal consumption increases, therefore, many power stations show a tendency to use blended coals [1]. In this paper, the effects of mixture ratio and heating rate on the combustion characteristics have been studied by TGA [2,3]. Many researchers have studied the co-combustion characteristics [4-6]. It is available reference for the effective development and economic utilization of coal blends. Experimental Materials and Equipment Materials Sample C was collected from Dongning Lujian Company. Sample D was obtained from Yanbian Yunming coal mine. According to the GB 474-474 standards, the particle size of the blends was <0.2 mm. The data on proximate and ultimate analyses of coal are presented in Table 1. The blending ratio (C/D) is shown in Table 2. Table 1. Proximate and Ultimate Analysis of Coal.

In this issue of the European Respiratory Journal, Pesavento et al. [1] present the results of the Study on the Clinical Course Of Pulmonary Embolism (SCOPE). In this huge effort, 647 consecutive patients with a symptomatic, confirmed first episode of acute pulmonary embolism (PE) were recruited and subjected to lung scanning after an initial treatment period of 6 months to assess the presence of residual pulmonary obstruction. Patients were followed for an additional 3-year period to monitor the occurrence of recurrent venous thromboembolism (VTE) and/or chronic thromboembolic pulmonary hypertension (CTEPH). The primary aim of the SCOPE study was to evaluate the predictive value of persistent perfusion defects for recurrent PE and CTEPH. Notably, 50% of patients were found to have some degree of persistent perfusion defects, with 56 (8.7%) patients having a persistent perfusion obstruction of >25% and none >72%. Both higher age (OR 1.03, 95% CI 1.02–1.04, per year) and unprovoked PE (OR 1.40, 95% CI 1.01–1.95) were predictive of persistent perfusion defects, whereas among others reperfusion therapy at baseline was not. During the 3-year follow-up period, 40 patients were diagnosed with recurrent VTE (6.2%; 95% CI 4.5–8.3) and 11 with CTEPH (1.7%; 95% CI 0.9–3.0). In multivariate COX regression analysis, persistent perfusion defects predicted the combined endpoint of recurrent VTE and/or CTEPH for an adjusted hazard ratio of 2.26 (95% CI 1.23–4.16). From these results, the authors conclude that a single assessment of persistent perfusion defects at 6 months may guide treatment decisions regarding duration of anticoagulation therapy.

Leadership style is a kind of method that aims to realize organizational targets and affect all organizational activities. This quantitative study focused on various business domains in Saudi Arabia to examine how leadership styles are related to human resource strategies and organizational performance. The study adopted the self-administered survey methodology technique using a pre-validated pre-piloted questionnaire. Data were analyzed using Structural Equation Modelling. A total of 270 questionnaires were distributed with a response rate 92.9% based on a convenience method. Our survey found a direct positive relationship between leadership style and organizational performance and an indirect relationship between leadership style and human resource strategy as a mediator, while human resource strategies contribute positively and significantly to organizational performance. The findings are relevant for operating human resource management strategies and for developing a style of leadership. An enterprise can use this information to promote recognition and devotion among its employees based on a range of strategies, and then creates overall performance of the organization. Also, it is possible to use different leadership styles for different strategies. Consequently, this study has both theoretical and practical reference value.


ABSTRACT: In social life, the law has many functions. In this case the law became a tool in resolving the conflict in Aceh. The conflict in Aceh has long occurred. Several rounds of dialogue has been conducted, but has not achieved satisfactory results. Dialogue after the tsunami last December 26, 2004, facilitated the Crisis Management Institute (CMI), the conflicting parties and the Government of the Free Aceh Movement reached a peace agreement. In peace, produced a memorandum of understanding (MoU) signed in Helsinki on August 15, 2005, in which the MoU is to be hold in drafting a legislation for Aceh, which was then named the Law Number 11 Year 2006 on the Government of Aceh.

We present a unified model of sovereign debt, trade credit and international reserves. Our model shows that access to short-term trade credit and gross international reserves critically affect the outcome of sovereign debt renegotiations. Whereas competitive banks do optimally lend for the accumulation of borrowed reserves that strengthen the bargaining position of borrowers, they also have incentives to restrict the supply of short-term trade credit during renegotiations. We first show that they effectively do so and then derive propositions that: I) establish the size of sovereign debt haircuts as a function of economic fundamentals and preferences; II) predict that defaults occur during recessions rather than booms, contrary to reputation based models; III) provide a rationale for holding costly borrowed reserves and, IV) show that the stock of borrowed international reserves tends to increase when global interest rates are low.

Wettability is a fundamental property that defines the fluid's distribution in oil reservoirs. Assessing wettability is required to model flow in porous media. Nevertheless, it involves complex intermolecular and surface forces. Contact angle measurement is a quantitative method to determine wettability. However, rock samples must be prepared to assure results representative of reservoir conditions. This work applies statistical analysis to investigate the relevance of variables involved in sample preparation (aging time, solvent used to remove the excess oil from the surface) and mineral type on the wettability of oil and brine from a Pre-Salt field on pure minerals. Since there is limited experimental wettability data at Pre-Salt conditions, this work aims to assist filling this gap. The results showed aging time and mineral type as the most important parameters for analysis. Furthermore, authors found that greater aging time in oil and point of zero charge of the mineral lead to a more oil-wet behavior.


We consider a class of multi-component hybrid inflation models whose evolution may be analytically solved under the slow-roll approximation. We call it multi-brid inflation (or n-brid inflation where n stands for the number of inflaton fields). As an explicit example, we consider a two-brid inflation model, in which the inflaton potentials are of exponential type and a waterfall field that terminates inflation has the standard quartic potential with two minima. Using the δN formalism, we derive an expression for the curvature perturbation valid to full nonlinear order. Then we give an explicit expression for the curvature perturbation to second order in the inflaton perturbation. We find that the final form of the curvature perturbation depends crucially on how the inflation ends. Using this expression, we present closed analytical expressions for the spectrum of the curvature perturbation PS(k), the spectral index nS, the tensor to scalar ratio r, and the non-Gaussian parameter f local NL , in terms of the model parameters. We find that a wide range of the parameter space (nS ,r , f local NL ) can be covered by varying the model parameters within a physically reasonable range. In particular, for plausible values of the model parameters, we may have a large non-Gaussianity f local NL ∼ 10–100. This is in sharp contrast to the case of single-field hybrid inflation in which these parameters are tightly constrained.


Bioanthropologists are often required to examine burned human remains recovered from archaeological and forensic contexts. Thus, as teeth are often the skeletal parts that better resist to fragmentation, understanding their heat-induced changes is essential to infer about context and burning conditions. The aim of this work is to report heat-induced modifications, namely those related to colour, fractures and mass, in human teeth experimentally exposed to different temperatures (400°C, 700°C e 900°C) and attempt to better clarify these phenomena in dental tissues. From teeth donated by patients after medical extraction, three subsamples of permanent teeth were selected: 10 lower second pre-molars, 10 upper central incisors and 10 upper first molars – of individuals of known sex and age. The teeth were cleaned, weighted and experimentally burned in an electric muffled Barracha K-3 thriphasic 14A with temperature increments between 3.3° C and 4.3°C per minute. Maximum burning temperatures for the three samples were achieved after 120, 210 and 240 minutes, respectively. Cement colour alterations progressed from a natural-looking shade to black/dark-brown (400° C), light grey-brown (700° C) and white (900° C). In turn, the enamel colour changes progressed from a natural-looking shade to beige (400° C), light-grey (700° C) and dark-grey (900° C). Additionally, it was observed that temperature increments caused an increase in the number of fissures and in mass loss. In the latter, most of it seems to have happened at temperatures up to 700oC. Beyond this temperature, mass loss was mild. This investigation contributes to a better understanding of the effects of heat in human teeth.

Abstract The characteristics of a slot antenna on a perfectly conducting elliptic cylinder coated by confocal chiral media are investigated. The structure is fed with a line source or a plane wave. The analysis is carried out by expressing the fields in and around the cylinder in terms of Mathieu and modified Mathieu functions using the separation of variable and exact boundary value technique. The unknown aperture field is expressed in terms of Fourier series with unknown expansion coefficients. The expansion coefficients are found by applying the boundary conditions on different surfaces and employing the orthogonality of the Mathieu functions. For TM and TE cases, some numerical results of the gain and coupled field pattern for co- and cross-polarized waves are presented and discussed.


Abstract 4423 Background Dysregulation of energy metabolism is a key feature of malignancy and known to be regulated by epigenetic mechanisms. This study explores gene expression in the KG1 cell line and a primary culture of leukemic blasts from a patient, both incubated with SAHA (suberoyl anilide hydroxamic acid, also known as Vorinostat) in comparison to other epigenetic drugs such as Decitabine (DAC) but also nutritional compounds such as genistein and vitamin D3 with a known activity on metabolism where epigenetic mechanisms play a role. Methods Following a 3 days incubation with pharmacologic concentrations of the above mentioned compounds, gene expression patterns of the KG1 cell-line were analysed on an Affymetrix Gene Expression Array and specifically evaluated by quantitative real time PCR from KG1 cells and primary leukemic cells of a patient with an AML-M2 which were cultured at the same conditions as the KG1 cells. In order to confirm epigenetic mechanisms induced by targeted drugs, methylation patterns of selected tumor suppressor genes were analyzed using specific primers for bisulfite-treated DNA. Results Our experiments show that expression of a large scale of micro RNAs which are known to be responsible for alternative splicing is stimulated by SAHA as well as DAC and to a lesser extent also Vitamin D3 and genistein, but downregulation of mitochondrial RNAs as a consequence of apoptosis was exclusively observable by SAHA. HDAC-inhibition results in clear repression of metabolic genes involved in glycolysis (5/6 genes) as well as cholesterol-biosynthesis (14/15 genes) and fatty acid synthesis (all 4 genes) which are also known to be regulated by nutrition. Classic tumour suppressor genes, transcription factors and cell-cycle regulators such as P53, P15, P16 and P21 and FOXO were (re-) activated with this treatment while MYC was down-regulated. Discussion A downregulation and thus normalization of a large scale of genes including key genes from malignancy-associated stimulation of glycolysis as well as biosynthesis of cholesterol and fatty acids was observed with SAHA and nutritional compounds such as Vitamin D and genistein. We propose that these interactions should be carefully considered in clinical application, and a combination of synergistic drugs and/or dietary strategies may provide a major advantage in future drug development.

Objective: To find out whether initiating external cephalic version (ECV) earlier in pregnancy increase therate of successful ECV procedures, and be more effective in decreasing the non cephalic presentations atbirth and also cesarean section rate. Methodology: This interventional study was conducted in Department of Obstetrics and GynecologyMardan Medical Complex from first July 2010 to 31st Dec 2011.It included women with singleton breechfetus at a gestational age of 34 to 35 weeks. Patients were randomly divided into two groups, those havinga first ECV procedure between 34(238 days) and 35 weeks of gestation were called early ECV group thesecond group included those who had first ECV at or after 37 weeks(259 days) and were called delayed ECV group. Percentages were calculated for qualitative variables like Gravida, complications etc, whilemean and SD for quantitative variables like gestational age. Results: Out of total 203 women who had breech presentation 123 were finally selected for the trial. EarlyECV group included 63 patients while delayed group included 60 patients..Fewer fetuses were in noncephalic presentation at birth in the early ECV group (41/63[65%] versus 29/60[49%] in the delayed ECVgroup, p = 0.04. There were no differences in rates of cesarean section (19/63[30%] versus 20/60 [33%],p=0.42) in the early ECV group versus the delayed ECV group. The rate of preterm birth was not differentbetween groups, early ECV group (2/63[3%] versus 0/60[o], p=o.26) delayed ECV group. Conclusion: External cephalic version at 34 and 35 weeks increase the likelihood of cephalic presentationat birth but it does not decrease the rate of cesarean sections and may increase the rate of preterm birth inthe early ECV group.


We consider exponentially stable linear systems subject to heavy-tailed noise. Based on the distributional properties of the output dynamics, we introduce novel performance and risk indexes to evaluate system's response towards the exogenous and/or structural sources of noise. We derive explicit expressions of the aforementioned indexes whenever possible, as well as general spectral-related estimates. We apply the obtained rigorous results to improve systemic performance on a case study of a distributed consensus system.


The hybrid electric vehicle (HEV) has the potential of sufficing drive needs with better fuel efficiency. The complex nature of hybrid vehicle provides multiple opportunities for obtaining better fuel efficiency. The mathematical modeling is a necessity for understanding the behavior of HEV. The fuel efficiency is obtained through various means including the design of energy management system, component sizing, emission control, and other methods. In the present paper, a mathematical model of HEV is presented for a parallel HEV with a review of various methods used for fuel efficiency optimization.


The problem of online antisocial behavior is increasingly attracting public attention and is compromising the quality of online communities. Previous research on online hostility looked at different aspects of the problem such as its definition, classification, or studying specific case studies, however, the impact is still not clear. In this paper, we propose a new model to investigate the impact of antisocial behavior online, the model is based on the Unified Theory of Acceptance and Use of Technology (UTAUT), our model integrates the perception of antisocial behavior as a risk factor along with other factors drawn from sociology. Initial validation of our model was conducted through expert reviews, the reviews include interviews with experts from computer science, sociology, and psychology, who were asked to consider its application to Twitter (as one of the controversial cyberspaces when it comes to antisocial behavior). The results of both quantitative and qualitative analysis of the expert reviews show strong support to the proposed model.


While traveling to an unknown place via road navigation is critical, in the same way, the condition of the road is imperative to reach the destination within a certain time. Even though if we know the route of the source to destination but we are not aware of the condition of that road hence we are not able to reach within the desired frame of time. It could be avoided if you are aware of the condition of roads. This project aims at developing an Intelligent Vehicle road surface classifier system that categorizes road based on the roughness of the road. The core idea is to make available realtime information about the quality of the surface of the route along with navigation. the roughness of the road is calculated using the working piston movement of the suspension. Based on measured dynamic data, conditions of road will be analyzed, and we can upload this information on the central database so, in the future, any applicable end user can use this information during a traveling to get a brief idea about road conditions. Shock absorbers are a vital part of automobile suspension. Shock absorbers work on the principle of fluid displacement on the movement of the working piston of suspension in both compression and expansion cycle.

Degradation of methylene blue (MB) in textile water treatment was investigated by using the photo - Fenton method (mixture of Fe2+ and H2O2 with the UV irradiation) in the presence of nano-sized and low-cost catalyst Fe3O4/Zeolite A. This catalyst was synthesized by impregnation method; furthermore, its photo – catalytic performances and durability in heterogeneous Fenton system were evaluated. Both the structure and the physical chemistry properties of the photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM). The study investigated the influences of different parameters of the MB decolorization efficiency such as initial concentration of peroxide attending the Fenton reaction, amounts of catalyst, pH of the dye solution and comparison of utilization of H2O2 in two cases with and without UV lamps. Under the optimum conditions which is the initial concentration of MB is 50 ppm and pH of dye solution is 3, high efficiencies of degradation were achieved – performance of 92.49%. These results suggest that the low-cost nanostructure catalyst Fe3O4/Zeolite A may be the considerable option because of the durability and the stability in the photo – Fenton reaction for organic wastewater treatment in textile industry.


This paper proposes a novel on-road vehicle detection algorithm for Advanced Driver Assistance Systems. The proposed algorithm uses shadow and edge information of original image to generate the candidate vehicles. The proposed algorithm extracts the shadow region darker than the road, and creates an edge image using the Canny edge detector. It performs AND operation between the shadow image and the edge image. The candidate vehicles are verified by SVM classifier based on the HOG feature vector. The experimental results show that the proposed algorithm provides fast and accurate vehicle detection. And the number of candidates is reasonable for the vehicle verification.

T he COVID-19 pandemic and post-surge planning highlights the significance of preoperative optimization in a way previously unrecognized in the perioperative period. Published protocols have largely emphasized planning for the intraoperative period with less attention afforded to reporting the design, implementation, and scaling of preoperative considerations and testing for long-term safety strategy. We present 2 transformative and sustained changes to our preoperative assessment process initiated during the COVID19 surge that were pivotal to our success in resuming elective surgeries. These preoperative interventions are the ''overnight'' transition to 100% virtual clinic appointments and the widespread implementation of multiple COVID-19 testing pathways. The improvements were accomplished by redeployment of preoperative clinic staff to a work-at-home model, moving to preoperative video visits, incorporating universal COVID-19 screening, and the development and refinement of previously non-existent preoperative respiratory pathogen testing protocols. In the post-COVID pandemic era, federal, state, and county regulators and national medical societies have established principles to resuming elective surgery. These center around evaluation of timing of reopening based on local cases, availability of COVID19 testing in the facility, supply of personal protective equipment (PPE), and prioritization of cases and scheduling. When the California ban on elective surgery was lifted on April 23, 2020, Stanford Health Care (SHC) and Lucille Packard Children's Hospital had already drafted preliminary plans for resuming elective procedures. Our health system's thoughtful and preemptive perioperative preparation was based on rapid iterations from multidisciplinary teams that had commenced a month earlier when we ceased perform-

This article mainly under the green economic visual field, research into the necessity, the obstacle factor and its motive source of development green economy in the building new countryside.


Recently, the number of patients with diagnosis of chronic diseases has significantly increased in western societies. This growth implies an increase in both costs and resources for the health system as well as in the number of trips to health centers by this class of patients. Mobile communication technologies can be exploited to get reduced costs whereas chronic patients and their relatives can improve their quality of life. Otherwise, wireless communications can be affected by interference generated in patients' home environments. In this paper, we present a work which implies a change in the concept of health services and distance monitoring of patients with chronic diseases whilst helps to improve assistance quality as well.


The experimental determination of the quantum critical point (QCP) that controls the self-organization of charged striped domains in cuprate perovskites is reported. The phase diagram of doped cuprate superconductors is determined by the hole doping δ and by a second variable: the micro-strain e of the Cu–O bond length. We have determined the Tc(e,δ) phase diagram by measuring the micro-strain e by Cu K-edge EXAFS. The superconducting phase occurs around the QCP at the critical strain where Tc reaches its maximum. The critical charge, lattice and spin fluctuations near this strain QCP provide the singular interaction for the pairing and show self-organization of local lattice distortions into a metallic superlattice of quantum wires "superstripes" that favors the amplification of the critical temperature.

The article tells about the Far Eastern librarian Nadezhda Abramovna Kanover, a follower of the bibliographer Z.N. Matveev, who played a great role in the development of librarianship in Vladivostok. The publication is based on the documents from the Current Archive of the Presidium of the Far East Branch of Russian Academy of Science (FEB RAS), Central Scientific Library (CSL) of FEB RAS and Society for Study of Amur Region (SSAR) that for the first time reveal unknown facts from N.A. Kanover life and characterize the situation in library science in the Russian Far East in 1930s — 1950s. Heading several libraries including the future CSL FEB RAS and library of Primorskiy branch of State Geographical Society (SFGS), N.A. Kanover put much efforts in collecting collections and making conditions for book storage, as well as promoted book culture by publishing articles and organizing book exhibitions. Thanks to her, Vladivostok received a unique old-believers' collection that belonged to bibliophile S.Ya. Ponosov. Printed editions of the collection are now kept in the SSAR library (former SFGS library), icons and religious artefacts are in the Primorsky Picture Gallery and the V.K. Arsenyev Museum of Far East History. These organisations presented a part of Ponosov's collection at the joint exhibition "Legend of Belovodie" (Vladivostok, February 18 — July 30, 2023). The pages of Kanover's biography connected with the last months of life of V.K. Arsenyev, the famous traveller and explorer of the Far East, are remarkable. While working in the library of SFGS, N.A. Kanover became its last secretary, dealing with the correspondent network of the branch. Unfortunately, almost nothing is known about the last years of her life, but N.A. Kanover's work in the field of Far Eastern library science is not forgotten.


Currently, over a third of children not in school live in countries considered being as fragile or affected by an armed conflict. These countries, which are mainly located in sub-Saharan Africa, will not reach the objectives of Education For All for 2015. This paper covers approaches across comparative education, political science and sociology of organizations. The question is: what prospects for international assistance on education in fragile states and countries affected by armed conflict? Our study explores empirically the conditions of intervention of international aid within the contexts of fragility and armed conflict. Insofar as investment in education is perceived as a necessary, if not sufficient, to vanquish poverty, the option to stimulate and accelerate the development of education constitutes an opportunity for the international community. Even if it means that the latter also has to exercise some forms of interference. The findings of our empirical analysis (panel data over the period 1999-2010) show, that within fragile states, the emergence of a current contradiction between the inclusive nature of the EFA goals and the exclusionary nature of the paradigms on which foreign aid is based (effectiveness and results). This situation leads us to question the approach of aid which is torn morally between the consequences of individual actions or common actions where the financial criteria and instruments are clearly not adapted to situations of fragility. This paper concludes with some recommendations and perspectives, particularly in the context of the post 2015.

A flux qubit can interact strongly when it is capacitively coupled to other circuit elements. This interaction can be separated in two parts, one acting on the qubit subspaces and one in which excited states mediate the interaction. The first term dominates the interaction between the flux qubit and an LC-resonator, leading to ultrastrong couplings of the form $\sigma^y(a+a^\dagger),$ which complement the inductive $\sigma^xi(a^\dagger-a)$ coupling. However, when coupling two flux qubits capacitively, all terms need to be taken into account, leading to complex non-stoquastic ultrastrong interaction of the $\sigma^y\sigma^y$, $\sigma^z\sigma^z$ and $\sigma^x\sigma^x$ type. Our theory explains all these interactions, describing them in terms of general circuit properties---coupling capacitances, qubit gaps, inductive, Josephson and capactive energies---, that apply to a wide variety of circuits and flux qubit designs.


The photopolymerization process of acrylate coat- ings initiated by visible light (k > 380 nm) and performed in air was studied in the presence of zirconium complexes. Depth profiling experiments were performed using confocal Raman microscopy showing that the conversion, which is low at the surface of the sample, increases with increasing depth and reaches a full conversion close to the substrate. RT-FTIR spectroscopy corroborates Raman results in evidencing the efficiency of some zirconium compounds to reduce oxygen in- hibition. Finally, laser flash photolysis experiments revealed that the beneficial effect in air is attributable to the reaction of the zirconium complex on the peroxyl radicals formed from the reaction of oxygen with radicals. Therefore, the oxygen present in the medium is depleted, allowing a better effi- ciency of the photopolymerization process. V C 2011 Wiley Peri- odicals, Inc.

Background: SCARB2 is the cellular receptor for EV71. Results: Seven highly variable amino acids on SCARB2 and a region in proximity to residue Gln-172 of VP1 are critical for EV71 infection. Conclusion: EV71 might adopt the canyon receptor engagement mode for viral entry. Significance: Elucidation of receptor and viral determinants revealed a possible target for anti-EV71 interventions. Enterovirus 71 (EV71) is one of the major pathogens that cause hand, foot, and mouth disease outbreaks in young children in the Asia-Pacific region in recent years. Human scavenger receptor class B 2 (SCARB2) is the main cellular receptor for EV71 on target cells. The requirements of the EV71-SCARB2 interaction have not been fully characterized, and it has not been determined whether SCARB2 serves as an uncoating receptor for EV71. Here we compared the efficiency of the receptor from different species including human, horseshoe bat, mouse, and hamster and demonstrated that the residues between 144 and 151 are critical for SCARB2 binding to viral capsid protein VP1 of EV71 and seven residues from the human receptor could convert murine SCARB2, an otherwise inefficient receptor, to an efficient receptor for EV71 viral infection. We also identified that EV71 binds to SCARB2 via a canyon of VP1 around residue Gln-172. Soluble SCARB2 could convert the EV71 virions from 160 S to 135 S particles, indicating that SCARB2 is an uncoating receptor of the virus. The uncoating efficiency of SCARB2 significantly increased in an acidic environment (pH 5.6). These studies elucidated the viral capsid and receptor determinants of enterovirus 71 infection and revealed a possible target for antiviral interventions.


It is very important to evaluate thermal protective performance (TPP) in laboratory-simulated fire scenes as accurately as possible. For this paper, to thoroughly understand the effect of fabric deformation on basic physical properties and TPP of flame-retardant fabrics exposed to flash fire, a new modified TPP testing apparatus was developed. Different extensions were employed to simulate the various extensions displayed during different body motions. The tests were also carried out with different air gaps. The results showed a significant decrease in air permeability after deformation. However, the change of thickness was slight. The fabric deformation had a complicated effect on thermal protection with different air gaps. The change of TPP depended on the balance between the surface contact area and the thermal insulation. The newly developed testing apparatus could be well employed to evaluate the effect of deformation on TPP of flame-resistant fabrics.


Mixed crystals of tetrakis(3,4-dimethylphenyl)imidodiphosphate salts with alkalication ratios K⊕/Rb⊕ (1:5) and Rb⊕/Cs⊕ (1:1), (1:3) as well as (3:1) have been grown by suspending finely ground stoichiometric mixtures of alkali carbonates in toluene solutions of the strongly chelating ligand HN(PO(OR)2)2 - The cation ratios were measured by Total Reflexion X-Ray Fluorescence (TXRF) analysis and the single crystal structures of the polymeric K⊕/Rb⊕ as well as the Rb⊕/Cs⊕ imidodiphosphate salts determined by X-ray structure analysis. The selectivity of the various alkali ions for insertion in the crystal lattices of the individual imidodiphosphate salts has been confirmed by concentration-dependent crystallizations and discussed based on the structural analysis of the differing ligand conformations. The unit cell parameter dependence on the alkali cation radii provided information on van der Waals interactions between adjacent phenyl rings of the imidodiphosphate ligands and suggests the selective alkali cation insertion to be partly due to supramolecular repulsion within the lipophilic phenyl skin during the selfaggregation of the polymeric salt chains


Plato imputes an important form of understanding to Cephalus in Book I of the Republic and revisits it at the end of Book X. Plato's astute observations of mental life in old age tie Cephalus' conversation to the concept of "life review" in contemporary geriatric psychology. This provides the basis for an argument that Cephalus exemplifies the indispensable teacher described in Book X, and this raises interesting new epistemological and ethical issues. Finally, I ask why commentaries on the Republic have overlooked this theme, and argue that an ageist bias against Cephalus has distorted commentators' reading of the text.

The energy consumption of wireless interface is critical to power-constrained mobile devices. To improve energy efficiency for WLAN stations, power saving mode (PSM) is proposed, to manage the time spent in idle listening (IL) state. The hurdle is that the receiver has no knowledge about when the pending data will arrive under end-to-end communication protocols (TCP/IP), making each station spend enormous time in IL to wait for the pending data. To overcome this limitation, in this paper, we propose a named data networking (NDN) enabled PSM, namely, NDN-PSM, which leverages NDN communication architecture to cut down unnecessary IL time. In particular, we devise two new power states in NDN-PSM, i.e., light doze and deep doze, to precisely map to the underlying data arriving states. The inherent receiver-driven pattern of NDN can effectively drive the stations to the deep doze state for power saving, and to light doze state for timely data reception. Considering the IL time waste during channel contention, we further design a channel contention control mechanism in NDN-PSM, in which stations will switch to the light doze state if the channel is perceived to be busy. The power consumption model of the proposed NDN-PSM is theoretically analyzed and verified via numerical results. At last, we implement NDN-PSM in NS-3 by adopting the ndnSIM module and conduct extensive simulations to demonstrate the efficacy of NDN-PSM. Specifically, compared to the existing PSM mechanism, NDN-PSM reduces 56% power consumption by cutting down unnecessary IL time, and meanwhile enables low-delay transmission.


Water based mud is the most commonly used mud in drilling operation. However, it is ineffective when dealing with water-sensitive shale that can lead to shale hydration, consequently wellbore instability is compromised. The alternative way to deal with this kind of shale is using synthetic-based mud (SBM) or oil-based mud (OBM). OBM is the best option in terms of technical requirement. Nevertheless, it is toxic and will create environmental problems when it is discharged to onshore or offshore environment. SBM is safer than the OBM. The aim of this research is to formulate a drilling mud system that can carry out its essential functions for shale gas drilling to avoid borehole instability. Ester based SBM has been chosen for the mud formulation. The ester used is methyl-ester C12-C14 derived from palm oil. The best formulation of ester-based drilling fluid was selected by manipulating the oil-water ratio content in the mud which are 70/30, 80/20 and 90/10 respectively. The feasibility of using this mud for shale gas drilling was investigated by measuring the rheological properties, shale reactivity and toxicity of the mud and the results were compared with a few types of OBM and WBM. The best rheological performance can be seen at 80/20 oil-water ratio of ester based mud. The findings revealed that the rheological performance of ester based mud is comparable with the excellent performance of sarapar based OBM and about 80% better than the WBM in terms of fluid loss. Apart from that, it is less toxic than other types of OBM which can maintain 60% prawn's survival even after 96 hours exposure in 100,000 ppm of mud concentration in artificial seawater.


We propose an application of spectral decomposition using regularized non-stationary autoregression (SDRNAR) to random noise attenuation. SDRNAR is a recently proposed signal-analysis method, which aims at decomposing the seismic signal into several spectral components, each of which has a smoothly variable frequency and smoothly variable amplitude. In the proposed novel denoising approach, random noise is deemed to be the residual part of decomposed spectral components because it is unpredictable. One unique property of this novel denoising approach is that the amplitude maps for different frequency components can be obtained during the denoising process, which can be valuable for some interpretation tasks. Compared with the spectral decomposition algorithm by empirical mode decomposition (EMD), SDRNAR has higher efficiency and better decomposition performance. Compared with f − x deconvolution and mean filter, the proposed denoising approach can obtain higher signal-to-noise ratio (SNR) and preserve more useful energy. The proposed approach can only be applied to seismic profiles with relatively flat events, which becomes its main limitation. However, because it is applied trace by trace, it can preserve spatial discontinuities. We use both synthetic and field data examples to demonstrate the performance of the proposed method.


The purpose of this service activity is to increase public knowledge, especially mothers who have babies or children under five years (balita), about the posyandu program. Before starting counseling, a questionnaire was filled (pretest). Counseling uses power point media with the lecture, discussion and question and answer method, then after being given counseling, the same questionnaire was distributed again to be filled back (posttest), after the knowledge data before and after counseling had been obtained, then the data were analyzed using the Wilcoxon statistical test.Based on the results of community service activities in the work area of the Banjarmasin Kuin Selatan Village Cempaka Posyandu, it means that there is a significant difference in knowledge between before and after counseling using power point media, thus it can be concluded that the method of extension using power point media carried out in the work area of the Banjarmasin Kuin Selatan Village Cempaka Posyandu is able and successful in increasing the knowledge of mothers who have chldren under five years. It is recommended that the local public health service (puskesmas) can provide more intensive guidance and training to posyandu cadres, so that they can assist health workers in educating the public about health in general and information about the importance of posyandu and the activities at the posyandu itself as an effort to participate forming a positive perception of the posyandu

Background: Singlet oxygen (1O2) oxidizes targets through the production of secondary reactive oxygen species (SOS). Cancers induce oxidative stress changing with progression, the resulting antioxidant status differing from one patient to the other. The aim of this study was to determine the oxidative status of patients with resectable Non-Small cell lung cancers (NSCLC) and the potential influence of antioxidants, compared to sera from healthy donors. Materials and Methods: Serum samples from 10 women and 28 men, 19 adenocarcinomas (ADK), 15 patients N1 or M1 were submitted to a photoreaction producing 1O2. Then, samples were supplemented with vitamins (Vit C, Vit E), or glutathione (GSH). Results: Squamous cell carcinomas (SCC) and metastatic SCCs induced a lower SOS rate. While Vit C increased SOS in controls as in patients with metastases, Vit E or the combination of Vit E and C strongly reduced SOS. GSH alone lightly decreased SOS in controls but had no effect in patients either alone or combined with Vit C. Conclusion: In "early" lung cancers, SOS are comparable or lower than for healthy persons. The role of Vitamins varies with gender, cancer type, and metastases. This suggests that an eventual supplementation should be performed on a per-patient basis to evidence any effect.


The organization and delivery of emergency care are reviewed in a book based on the judgments of 28 national leaders in various fields. It is noted that acute illness has become a major health problem due to the rapid growth of the United States and the increased demands of consumers for improved medical care. Critical needs in the field of emergency care are identified as communications, prompt and proper rescue handling, rapid and careful transportation of victims, and adequate emergency care at hospitals. The long-term solution to the problem of injury is viewed as prevention through efforts made by educators, industrialists, engineers, public health officials, and private citizens. The statement is made that accidents are exceeded only by heart disease, neoplasms, and cerebral vascular disease as a major cause of death in the United States. The dimensions of the accident problem are explored. Other topics addressed are: motor vehicle trauma and emergency medical services; the provision of emergency care to cardiac patients; medicolegal implications of emergency care; and field treatment and transport of emergency victims. The importance of telecommunications, emergency medical technician training, and public education is stressed. Hospital education and training for emergency department personnel are detailed for physiciansmore » and nurses. Functional and design aspects of hospital emergency departments are described, and the role of community planning in the provision of emergency health services is considered. A checklist for airport disaster planning and a Michigan law regarding emergency medical services are appended.« less

Sensible resource management requires a thorough and detailed description of resource usage as the basis for static design decisions or dynamic resource trading. Such a description not only has to consider what resources are used and when, but also has to capture resource properties and resource interactions, for instance. In current practice, however, ad-hoc solutions predominate, only addressing selected resource types and isolated aspects. In this paper we pave the way for a uniform modeling technique for resource usage scenarios. We give a classification of resources, which covers both software and hardware resources uniformly, and discuss essential aspects of service provision, service requirements, and resource interaction. Based on these insights we present a structured description technique for hierarchically dependent software and hardware resources and propose a notation for basic description elements. The technique can be used for resource usage analysis over a wide range of abstraction levels and allows domain-specific description techniques to be integrated seamlessly, effectively side-stepping the limitations inherent to one-size-fits-all solutions.


The net value of farm production in Australia is forecast to double from last season to $5.4 billion. Increased earnings from a major recovery in winter crop production will be partly offset by lower returns from livestock as producers retain stock from sale to rebuild animal numbers. Winter crop production in 2003-04 is forecast to increase by nearly 22 million tonnes to 37.1 million tonnes. A harvest of this size would be the second largest ever, exceeded only by the 39.3 million tonnes in 2001-02. A stronger Australian dollar and weaker world grain prices in 2003-04 are forecast to contribute to the index of prices received by farmers falling by 4 per cent in 2003-04.


Data generators play an important role in algorithm design and optimization engineering. They are an important tool for modeling, benchmarking, scalability, and cost estimation. Graph generators have been an extensive area of research in last decade. With the unprecendented growth in Internet, WWW, and, social networks there was an immediate need to model and subsequently build generators that produce graphs reflecting structures of these domains. It was discovered in [6], [7] that such networks are fractal in nature (scale-free) and can be described via physical phenomena of "rich gets richer" or "prefrential attachement" [1]. The mathematical model that produces such fractal graphs is based upon R-MAT [2] or Kronecker Product [8] and is the central theory underlying the scale-free generators. A large body of work exist that utilize either of the mathematical models to develop scalable scalefree graphs [2], [10]. These works have contributed significantly towards development of network protocols, algorithms, and, architecture design. The community has paid little attention to generation of acyclic graphs. Acyclic graphs, much like scale-free graphs, appear in many areas of computation and engineering. Knoweledge representation, binary decision diagram, dependency graphs, semantic web, and, binaries of computer program to name of few. In the field of life-sciences and bio-informatics such strucutres are used to create ontologies that represent the compendium of factual information. In recent years the number and the sizes of ontologies has been growing steadily. It is important for the database and the computing world to be able to develop algorithms over such workloads to be better address the needs of the domain science. Unlike social networks and WWW, the workloads in life-science and knowledge engineering discplines are much more complex and include reachability and pattern queries, and, lowest common ancestors [4]. The size of ayclic graphs is not as large as the socialnetwork graphs (upwards of multi-billion edges) but they can potentially be many orders of magnitude larger then those present currently. This is particularly true in life-sciences, bio-informatics and knowledge representation domain. This is because disparate ontologies can reference entities across each other. In fact, the Gene Ontology, has been constructed by combining ontologies of sub-species. In this field we are witnessing almost exponential increase in number of ontologies due to technological growth in bio-informatics and capabilities in life-sciences research. Hence in order to drive and evaluate the next generation of information engines and tools an scalable graph generator


Abstract This article considers the treatment of causatives in Functional Discourse Grammar (FDG) in relation to questions regarding the division of labor between the Grammar and the Lexicon in Functional Discourse Grammar (FDG). The focus is on causative constructions in which the causativizer affixes to the verb in so-called polysynthetic languages. In this respect the article also contributes to the treatment of polysynthesis in FDG. The central question is whether the causative construction is a derived lexeme created in the lexicon and inserted into the grammatical structure as a single lexical unit, or whether it is created in the grammar as a synthetic construction involving two lexical units. The article describes the pertinent morphosyntactic and semantic properties of causative constructions in Blackfoot, a polysynthetic language belonging to the Algonquian language family. I show that such constructions contain two events, each with their own semantic properties including argument structure and modifiability. In FDG this is accounted for by analyzing the semantic configuration at the Representational Level of analysis as a complex Episode consisting of two States-of-Affairs, while analyzing the morphosyntactic configuration at the Morphosyntactic Level as a complex verbal Word containing two verbal Roots, one of which is the causativizer. The causativizer is analyzed as an independent verbal lexeme stored in the lexicon rather than as derivational morpheme. This analysis follows logically from the way in which FDG conceptualizes polysynthesis, namely as a morphological type which allows the presence of more than one lexical element within a single word.


This paper reviews the modern ideas on the process of gelation which have arisen from the analogy between gelation and percolation. The basic features which are common to all types of gels, colloidal or polymeric systems are first recalled; then after a simplified presentation of the percolation model, a few examples illustrating these concepts are chosen (for chemical gelation, a copolymerisation reaction and for physical gelation, the gelatin sol-gel transition). In conclusion, electron micrographs of gel networks (gelatin gel and an inorganic gel of thorium phosphate) are shown, which reveal the great diversity and complexity of the structures.


As a parent and a teacher educator, I am acutely aware of the need to "practice what you preach." Yet, in both roles, I often find it a challenging axiom to carry out. When I warned my eldest child about the latest research on sleep deprivation, I resolved to make adequate sleep a priority in my routine. Similarly, when I volunteered to develop and teach a capstone course for M.Ed. students based on analyzing one's teaching, I determined to analyze my own teaching. In this article, I focus on one component of that ongoing self-study: my analysis of two M.Ed. students' work in which they analyze two of their K-12 students' work. Through this embedded design, I completed the identical assignment that I required of my students. The Role of Self-Study There is increasing recognition of the role of self-study in building teachers' knowledge base. As teachers make decisions about what and how to teach, they draw upon a knowledge base that includes numerous types of knowledge (Carter, 1990; Shulman, 1987; Tom & Valli, 1990). This knowledge base is not static, but rather changes and expands throughout one's teaching career. An important method for expanding one's knowledge base is through critical inquiry and reflection on one's practice. The National Board for Professional Teaching Practice (NBPTS) proposes that "getting teachers engaged in a self-reflective teaching practice will improve the quality of teaching and improve student learning" (NBPTS, 1999a, p.7). The notion of learning from one's own practice stems back to the work of Dewey who advocated "a special kind of professional education, in which a curriculum of theory-in-practice dedicated to the understanding of theory-for-practice was at its heart" (Shulman, 1998, p. 523). When theory is linked to practice, teachers themselves can become a critical source of new professional knowledge. However, simply gaining experience is not equivalent to learning from experience. Prospective teachers, engaging in unanalyzed classroom experience, face a serious problem of coming to inappropriate conclusions "that will be reinforced by further unanalyzed experience on the job" (Feiman-Nemser & Buchmann, 1985, p. 68). Field experience for prospective teachers often serves to reinforce, rather than challenge, generic views of teaching gained through personal experience as K-12 students. Yet teaching involves complex, particular, and unpredictable situations. Ball and Cohen (1999) contend that teachers need to learn, both before and while teaching, how to learn in and from practice. Consequently, professional education should focus on systematic study of practice and "emphasize questions, investigations, analysis, and criticism" (p. 13). Given that every classroom and teaching situation is different, it is impossible for teacher education programs to prescribe appropriate strategies. Teachers need the skills and dispositions to analyze teaching and learning in order to adapt their practice. Recent approaches to teacher assessment include reflective practice as a key component of effective teaching. Although specific approaches differ, the conceptualizations of teaching underlying the standards and assessment criteria developed by the Educational Testing Service (ETS), the Interstate New Teacher Assessment and Support Consortium (INTASC), and the National Board for Professional Teaching Standards (NBPTS) emphasize reflective practice (Porter, Youngs, & Odden, 2001). Reflective practice is considered essential for competent teachers, whether beginning or experienced. The ETS and INTASC assessments focus on beginning teachers whereas the NBPTS recognizes accomplished teachers who have taught at least five years. The ETS suggests that competent beginning teachers reflect on classroom events to plan subsequent teaching and to improve skills over time; similarly, INTASC identifies the need for beginning teachers to continually assess the effects of their actions (Porter, Youngs, & Odden, 2001). …


Blocking artifacts continue to be among the most serious defects that occur in images and video streams compressed to low bit rates using block discrete cosine transform (BDCT) (e.g., JPEG, MPEG and H.263). In the proposed scheme a signal adaptive, space invariant & nonlinear filter is used to smoothen the DC sub image. The compressed image is divided into monotone & edge blocks based on the ac components present in each block. Then a Singular Value Decomposition filter is applied to the non edge blocks to remove the artifacts in the block. In the edge blocks the proposed filter is not applied since the artifacts in the blocks are not sensi tive to human visual system. As a result real edges in the blocks are preserved. Finally corner outlier is detected and removed using an algorithm. This paper focuses to remove the blocking artifacts while preserving the real edges. In this paper new evaluation parameter DMSD is proposed. Experimental results shows that this proposed method is an efficient one to remove the blocking artifacts &to improve the quality of the image.

In modern narratives, the island of Spinalonga appears an attractive tourist destination with an interesting and enigmatic history. In fact, Spinalonga is a memory space, encumbered with past political decisions and medical negligence. This is the story of the great confinement, the isolation of the sick who were symbolically killed. Meanwhile, the photos shared on Instagram show theisland in a completely different light.The article seeks to answer the following questions: Does the behavior of Instagram users disrupt the culture of memory and how do these photos (digital representations of memory) influence the image of the island? To this end, I outline the history of the island in the context of exclusion mechanisms for those with Hansen's disease. I discuss the issues of dark tourism, social photoand desemantization of communication. I juxtapose the whole thing with the examples of photos from Spinalonga published on Instagram in 2022.


Elliptic curve cryptography provides a widely recognized secure environment for information exchange in resource-constrained embedded system applications, such as Internet-of-Things, wireless sensor networks, and radio frequency identification. As the elliptic-curve cryptography (ECC) arithmetic is computationally very complex, there is a need for dedicated hardware for efficient computation of the ECC algorithm in which scalar point multiplication is the performance bottleneck. In this work, we present an ECC accelerator that computes the scalar point multiplication for the NIST recommended elliptic curves over Galois binary fields by using a polynomial basis. We used the Montgomery algorithm with projective coordinates for the scalar point multiplication. We designed a hybrid finite field multiplier based on the standard Karatsuba and shift-and-add multiplication algorithms that achieve one finite field multiplication in m 2 clock cycles for a key-length of m. The proposed design has been modeled in Verilog hardware description language (HDL), functionally verified with simulations, and implemented for field-programmable gate array (FPGA) devices using vendor tools to demonstrate hardware efficiency. Finally, we have integrated the ECC accelerator as an AXI4 peripheral with a synthesizable microprocessor on an FPGA device to create an elliptic curve crypto-processor.


In large-scale cloud storage systems, Solid-State Drive (SSD) has been broadly used as the mainstream storage device because it has the advantages of low access latency and high throughput. However, conventional SSD is a black-box system to host softwares, thus failing to fully exploit the benefits of NAND flash and provide high quality of service (QoS). On the other hand, Open-Channel SSD (OCSSD) which exposes its internal information to the host software, has the potential to solve this problem. However, existing OCSSD fails to achieve anticipated performance under heavy workloads. To this end, we propose an advanced OCSSD-based driver developed with the novel data placement policy, redefined garbage collection (GC) with copyback technique, efficient prefetch read scheme, and fast live upgrade method. Our work describes the consistent efforts to pursue high performance and QoS in OCSSDs with different approaches. The evaluation results show that our novel Open-Channel SSD is able to provide high I/O throughputs and predictable I/O latencies. For example, our Open-Channel SSD can improve I/O throughputs by 103% and reduce the 99th percentile latency by 62.9% on average compared with the state-of-the-art NVMe SSDs.


The present work presents a preliminary research work about electrical treeing inception and growth in polymer-layered silicate nanocomposites. Different silicates were dispersed in an ethilene-vynil acetate (EVA) co-polymer matrix: unmodified and organically modified synthetic fluorohectorite, as well as organically modified natural montmorillonite, were considered. A microcomposite and two nanocomposite compounds were thus obtained and their behaviour under diverging electric field is here investigated and compared to base EVA. In an early stage two parameters were taken into account: treeing inception voltage (TIV) and breakdown voltage (BDV). Then, some short term duration tests have been performed, too. The experimental outcome of this investigation (morphology studies and electrical treeing tests) can offer a basis to further understand how the presence of a layered inorganic nanofiller can influence the short term electric performances of nanostructured polymeric materials.


Introduction/ Background Ki67 is an important immunohistochemical marker of proliferation used in grading of breast cancer and endocrine neoplasms. Ki67 proliferation indices (PI) are calculated as number of Ki67 positive tumour cells divided by total number of tumour cells. However, manual counting and calculation of Ki67 proliferation index is laborious and prone to inter-observer variability. Recently, a computerized algorithm that enables virtual alignment of two consecutive slides stained for pancytokeratin and Ki67 has been developed. Digital image analysis (DIA) based on Virtual Double Staining (VDS) enables exclusion of stromal cells and calculation of Ki67 PI in tumour cells only.


Detection schemes that utilize hard decision feedback (HDF) have not found practical applications in magnetic recording (MR) because of the detrimental impact of error propagation on the performance of the outer error-correcting code. In the context of turbo equalization of high-density MR channels, we study the impact of the error propagation on the performance. Through the extrinsic information transfer chart and the so-called worst case (rather than average) simulated trajectory of mutual information, we demonstrate that under strong residual intersymbol interference, error propagation is efficiently suppressed if soft decision feedback is used in place of HDF.


Despite severe concerns by members of his own military top brass and security circles, on 14 April, 2021, US President Joe Biden announced the unconditional withdrawal of all combat troops by 11 September of the same year. The US does not only thereby relinquish the opportunity to conduct counter-insurgency campaigns against the Taliban, it will also lose any capacity to conduct counter-terrorism operations against al-Qaeda and other international terrorist groups present on the ground. Furthermore, this stands in sharp contrast to his own earlier points of view, particularly those held as Vice-President (2009-2017), when under President Obama he advocated for a less troop-intensive but more engaged counter-terrorism presence in Afghanistan. Despite much disenchantment regarding nation-building efforts, endemic corruption, and the inability to bring stability to the country despite a massive troop surge, Biden was then not willing to abandon Afghanistan. President Biden obviously changed his opinion – to the disadvantage of the Afghan state and society.


Due to the fictitious character of internet, the actions of crime on the internet usually appeared transnational character. The actions of crime of transnational cyberspace mainly include crimes which take the internet as object, which take the internet as tools, and some other crimes which are relative to internet. Considering the transnational characteristic of cyberspace crime, international society should crack down on cyberspace crime harmoniously through international legislation.


A chiral synthesis of the Sceletium alkaloid
(-)-mesembranol 1 is described. The cyclohexane ring in 1 is
prepared in an optically active form from D-glucose using
Ferrier's carbocyclisation, and the critical stereochemistry of
the quaternary carbon in 1 is constructed stereoselectively via
chirality transfer by way of Claisen rearrangement of the
cyclohexenol derivative 14a. The perhydroindole skeleton in 1 is
effectively generated by intramolecular aminomercuriation of the
amino-olefin 18.


With the discovery of chemical weapons, mankind has faced a great threat. The fact
that these weapons caused mass human deaths and were relatively easy to develop made
the countries obliged to take precautions in this regard. During World War I, nearly 2
million people died due to chemical weapons. Nerve agents started to be used in making
chemical weapons before World War II began. Thus, the threat of chemical weapons
on humanity has reached a much more critical point. Especially the development of
chemical weapons and the production of nervous agents increased during World War II
and during the cold war. Chemical weapons developed by the countries started to fall into
the hands of terrorist groups. Sarin gas was used in the terrorist attack that took place
in Matsumoto, Japan in 1994. This incident went down in history as the first terrorist
attack in which sarin gas was used. These events show how critical it is to take action
against chemical warfare agents. The first method of protection from the toxic effects
of chemical warfare agents is to destroy the toxic effects by breaking down chemical
warfare agents. In this study, the metal organic frames used for this purpose in recent
years will be mentioned.


The partition coefficients of baicalin were measured in ethylene oxide and propylene oxide (EOPO)/salt aqueous two-phase systems at 298.15K. It was found that most of baicalin partitioned into EOPO-rich phase. The partition coefficients of baicalin varied from 10 to 120. The effect of various factors, including tie-line length, salt composition, molecular weight of EOPO, and solution pH, on the partition behavior was investigated in EOPO/salt systems. Furthermore the partition coefficients of baicalin were correlated using the modified Diamond-Hsu model. Good agreement with experimental data is obtained. The average relative deviations are less than 5.0%.


PurposeThis paper employs nationwide, large-scale field survey data to provide the first empirical evidence on the impact of human educational capital on the acquisition of health entitlement among Chinese migrant workers. The findings of this study hold significant practical implications for the formulation of policies aimed at improving the health protection of migrant workers, as well as for socioeconomic policies during China's transitional period.Design/methodology/approachUsing the IVProbit model, this research examines how human educational capital influences the attainment of health entitlement among migrant workers in China by analyzing the impact and mechanism of education on health entitlement. The study is based on the China Migrants Dynamic Survey (CMDS) data from 2018, which include 100,177 observations.FindingsFor migrant workers in China, higher levels of education have a significant positive effect on the acquisition of health entitlements, including medical insurance, health records and health education. The positive impact of human educational capital on health entitlements is more significant for non-provincial cities and young-generation migrant workers. The results also show that human educational capital can influence the acquisition of health entitlements through mediators such as financial status, social integration and health status.Originality/valueThis study represents the first empirical attempt to evaluate the influence of human educational capital on the access of migrant workers in China to health rights and interests. Additionally, the study develops a theoretical framework to examine how the impact of human educational capital varies across migrant workers with different characteristics and their access to health entitlements.


Convergence is currently melding entire disciplines to fully new business models and technologies across industries. What used to be embedded systems, on the one hand, with their specific constraints from the physical environments, and IT, on the other hand, are combining.1,2 This will impact education programs as well as classic industry boundaries.


Relics are non-renewable cultural resources. Advanced surveying techniques can be utilized to establish an intelligent management system,which connects with 23-D relics' information platform to form integrated platform featuring information and management functions. This platform will not only revise the defects in traditional practices but also conduct scientific analysis and implementation. We will be able to fully understand the path,pattern and implication of human history.


A communication system in which some large number of portable notebook computers access a centrally-located base station by means of a shared, high-speed, radio-based LAN is considered. The delay and throughput performances of two alternative approaches are compared: one high-speed channel shared by all portable remotes versus several moderate-speed channels, each shared by a subset of portable units. In both cases, access to the intended services is impeded by contention for the medium and queueing for some shared server (processor or database). Both systems are modeled as closed-queueing networks, and expressions for system throughput and average request delay are obtained. Numerical results show that over a wide range of parameters, the system containing one high-speed channel outperforms the system containing several parallel medium-speed channels by less than 10%. >


The covid-19 pandemic determined that different governments established mandatory confinement or quarantine; for this reason, the education had to be carried out at a distance or remotely; However, some universities already taught this modality; on the other hand, these changes caused discontent for many students because they were forcibly drawn to this modality without having been the choice for their professional training. In this context, the role played by the academic guide turned out to be fundamental to motivate and keep them hooked, preventing students from abandoning their careers. The objective of the study was to determine the relationship between the accompaniment of the academic guide and the level of academic satisfaction in the students of a private university during the COVID-19 pandemic. The quantitative approach method was used. From the statistical processing, it was concluded that there is a significant relationship between the variables academic guidance and academic satisfaction.


In this study what is to be controlled is the NCS(networked control system) of a singular control system.A discrete singular control system model with uncertainty and time-delay input is thus developed,where the sensor/actuator is time-driven with controller event-driven and the network-induced time-delay is shorter than a sampling cycle.The conditions of system stability are given by means of Lyapunov function and LMI,and a controller is designed satisfying both system stability and H∞ control state feedback to study the robust H∞ control.A simulation as example is given to verify the validity of the approach proposed.


Key Points Question To what extent does stage shift act as a confounding variable in the evaluation of population mortality of non–small cell lung cancer? Findings In this cohort study of 312 382 patients, stage shift from later to earlier stage disease over the last decade was associated with improved mortality among people with lung cancer. Meaning These findings suggest that studies investigating treatments for lung cancer must take into account stage shift and the confounding association with survival and mortality outcome.
