This bachelor thesis' focus is on primary school teachers' awareness of ADHD syndrome. The first part of the thesis contains theoretical basis connected to ADHD specifications in both the general level and the context to teaching an individual with this disability. At the same time there is an emphasis on defining a teaching profession with an accent on a teacher's competence and on future professional growth. The empirical part, using a survey research, is aiming to map to what depth of information do primary school teachers possess about ADHD syndrome, and to come with practice recommendations based on the acquired findings.


Ninety Holstein heifers were used to examine the effects of Rumensin® or Bovatec®. Average daily gain and feed efficiency was greater for heifers fed Rumensin® than for heifers fed Bovatec®. Heifers fed Rumensin® consumed more total dry matter per day but slightly less dry matter as a percent of body weight than heifers fed Bovatec®. No differences were observed in body condition score and hip height between dietary treatments. The primary goal of a heifer-feeding program is to obtain a desired rate of gain without fattening at the least possible cost. Results of this study support the use of Rumensin® in diets for growing dairy replacement heifers.

This work involves synthesis of activated carbon from Iraqi date palm seeds as agricultural wastes using kehdrawy palm seeds. The preparation was conducted by chemical activation method using ZnCl2 as an activator. The synthesized activated carbon (AC) was characterized by different analytical and spectroscopic methods. This involves using scanning electron microscopy (SEM), flourier transformation infrared (FTIR), ash content, adsorption capacity, the percentage of humidity and the point zero charge (PZC). The activity of the prepared activated carbon was investigated by following the removal of reactive yellow 145 dye (RY 145) from the aqueous solutions. For a comparison a sample of nonactivated carbon (NAC) was used in the same process. From the obtained results it was found that AC was more efficient in dye removal in comparison with NAC under the same conditions


weeding the fiction collection. The difficulty arises from the necessity of confronting your own mistakes, biases, and inadequacies simultaneously. Examples abound all those underused duplicates of an overhyped bestseller that all the potential readers were sick of before it ever got published; discovering a gem that has not circulated in years because you had never read it or knew you had readers for it before contemplating its removal from the collection; finding a title included on a nationally recommended list that indicates quality but none of your readers seem to care; and so on. Do you just trash the duplicates? Weep and trash the gem? Keep the listed title forever just to prove you care about "serious" readers? Merchandise all of them

The original Beranger drawing was executed on a visit to the island on Jun 24th-26th, 1779, as recorded in Sir William Wilde's "Memoir of Gabriel Beranger" (Dublin, 1880), pages 46-48, and in a letter from Beranger published in "Ireland of the Welcomes" (September-October 1993), pages 30-34. Inscribed on the page facing the image in 'Antiquities of Abbeys' is as follows: "Built without Cymetry [sic], of rude Stone work without mortar. The Cells DDE are under Ground [sic], as is all the part which is slightly shaded. Some Cells fallen in, they look horrid gloomy having a hole at the Top to give light, & sometimes a kind of Spike hole in the Side Wall. The Cell E is stopped & fallen in. The Cell F stands by itself". This plan was engraved and published as Fig. 1 of Plate 122 in Grose's Antiquities of Ireland, printed probably in 1796, but without any acknowledgment to Beranger as original draughtsman of the plan. It could be that Edward Ledwich who edited Grose's Antiquities probably depised Beranger or vice-versa. This drawing is a copy of Beranger's original created by Austin Cooper. (www.nli.ie)


The Distrito Federal, one of the most important centers of plant endemism in central Brazil, is located in the center of Brazil, with an area of 5,814 km2 at coordinates 15o30' S, 16o03'W. Cerrado vegetation covers the region. The main city in the Distrito Federal is Brasilia, the capital of Brazil with a population of 2.5 million. In the last two decades the anthropogenic action has reduced the original plant cover drastically. In this paper a checklist of the bryophytes (Marchantiophyta, Bryophyta and Anthocerotophyta) is presented. A total of 176 species are listed, 114 among Bryophyta, 61 among Marchantiophyta and 1 in the Anthocerotophyta. The families best represented are the Bryaceae and Sematophyllaceae (Bryophyta), and the Jubulaceae and Lejeuneaceae (Marchantiophya).


Rough sets are applied to data tables containing missing values. Discernibility and indiscernibility of missing values are considered simultaneously. A family of possible equivalence classes is obtained, in which each equivalence class has the possibility that it is an actual one. By using the family of possible equivalence classes, we can derive lower and upper approximations, even if the approximations are not obtained by previous methods. Furthermore, the lower and upper approximations coincide with ones obtained from methods of possible worlds.


We present the results of a series of detailed numerical simulations of the Rayleigh-Taylor instability in laser ablatively accelerated targets for a fairly wide range of initial conditions. It is shown that the Rayleigh-Taylor growth rate in an ablative environment is a strong function of the laser wavelength. For perturbation wavelengths about 3 times the inflight target thickness, the ratios of the numerical growth rates to the classical growth rates are of the order of 1/1.5, 1/2.5 and 1/3.5 for 1, 1/2 and 1/4 ..mu..m laser light, respectively. The numerical results are in good agreement with our theoretical model, based on the ablative convection of vorticity away from the unstable ablation front. These results provide strong evidence for the viability of high-aspect-ratio shells in direct-drive laser fusion.


In a simple model for the long-time dynamical behavior of Brownian suspensions, particles diffuse independently while simultaneously undergoing direct interactions with each other. Despite its simplicity, this model forms the basis of both the Brownian dynamics computer simulation technique and apparently successful theories. Here we use the approach to study numerically the viscoelastic response of a suspension of hard spheres. At low volume fractions (10%) we find that the frequency dependence of the viscosity is in agreement with theoretical calculations based on solving the two-particle Smoluchowski equation. At a higher volume fraction (45%) we find that the model is not well described by various extensions of low density theory that have been proposed. Including hydrodynamics in a minimal way (by allowing the particles to diffuse with the short-time diffusion coefficient) and comparing with experiment, the model successfully reproduces the viscoelastic response over an intermediate range of frequenc...


Christianity has incorporated both local traditions of worship and biblical symbolism as well as the majority of archetypical notions from Judaism, for instance, the concept of the Holy Land, which is associated with the meaning of sacral space or the sacrum, expressed by phenomena and the powers of nature. A green grove or a garden prompts spiritual values, praying and contemplation. The myth of the biblical paradise arising from Christian worship was one of the most important factors that shaped the attitude of man towards nature. Numerous images of the garden are in the background of scenes and depictions from the lives of Mary, Jesus and the saints, to whom trees and ß owers were assigned as attributes and ornaments. The tree itself receives a novel, universal dimension of a cross as the Tree of Salvation. The biblical spring was also depicted symbolically with a well or a fountain situated at the conß uence of alleys located in a garden (being its equivalent) on a square plane surrounded by walls. Four sides symbolized the


This paper proposes an Upper-Limb Exoskeleton actuated by a novel Series Elastic Actuator (SEA) for the purpose of rehabilitation training. In design, the exoskeleton features 7 Degrees of Freedom (DOFs), 4 of which are actuated by SEAs, so as to cover most of the human motion trajectories at the time of rehabilitation training. The elastic component of SEA includes the tension springs intended for circumferential arrangement. Showing a linear torque-deformation characteristic within its working range, the elastic component retains consistent rotary stiffness in both directions. In order to evaluate the dynamic performance of the exoskeleton, the experiment of a single joint force and position control is conducted in this exoskeleton. The result of the compliant joint's bandwidth reaches 6.1 Hz in force control and the tracking error is 0.3 Nm with a sinusoidal input torque with an amplitude of 3 Nm and a frequency of 1.5 Hz. Our result demonstrates an accurate force control and position regulation behavior that meets the requirement placed on rehabilitation training.

Let us reflect on the state of robotics. This year marks the $101$-st anniversary of R.U.R., a play by the writer Karel \v{C}apek, often credited with introducing the word"robot". The word used to refer to feudal forced labourers in Slavic languages. Indeed, it points to one key characteristic of robotic systems: they are mere slaves, have no rights, and execute our wills instruction by instruction, without asking anything in return. The relationship with us humans is commensalism; in biology, commensalism subsists between two symbiotic species when one species benefits from it (robots boost productivity for humans), while the other species neither benefits nor is harmed (can you really argue that robots benefit from simply functioning?). We then distinguish robots from"living machines", that is, machines infused with life. If living machines should ever become a reality, we would need to shift our relationship with them from commensalism to mutualism. The distinction is not subtle: we experience it every day with domesticated animals, that exchange serfdom for forage and protection. This is because life has evolved to resist any attempt at enslaving it; it is stubborn. In the path towards living machines, let us ask: what has been achieved by robotics in the last $100$ years? What is left to accomplish in the next $100$ years? For us, the answers boil down to three words: juice, need (or death), and embodiment, as we shall see in the following.


The general three-center one-electron nuclear-attraction integral with integer-n Slater-type orbitals is evaluated analytically by letting the orbital exponent of a 1s orbital in the analytical formula for two-electron three-center electron-repulsion integrals tend to infinity. The result is an infinite sum in which the internuclear angles appear in spherical harmonics, and the internuclear distances appear in modified spherical Bessel functions and exponential-type integrals.


A super‐tall building with height of 420 m and 88 floors is located in central Hong Kong. Field monitoring of wind effects on the high‐rise structure was conducted during the passage of several typhoons on the basis of a wind and movement monitoring system installed in the building. Field data such as wind speed, wind direction, pressures on cladding, acceleration and displacement responses were simultaneously recorded during the typhoons and then analyzed. Typhoon wind parameters including turbulence intensity, gust factor, peak factor, turbulence integral length scale and power spectral density were presented and discussed. The dynamic properties of the high‐rise structure were determined from the field measurements and compared with those calculated at the design stage. The damping ratios of the super‐tall building were evaluated by a random decrement technique, which demonstrates amplitude‐dependent characteristics. The relationships between the structural dynamic responses and the approaching wind speed were analyzed. Wind tunnel tests were conducted to investigate the wind effects on the super‐tall building. The field‐measured acceleration responses were found to be consistent with the model test results. Finally, the serviceability performance of the super‐tall building during the typhoons was assessed on the basis of the field measurement results. The findings of the paper are expected to be of considerable interest and practical use to professionals and researchers involved in wind‐resistant designs of super‐tall buildings.

Better is the technology; better is the livelihood of farmers' community. The correlation between technology and rural development is highly positive. An agrarian technology apart from ensuring better production should also lead to better remuneration. SRI is one such technology that not only augments rice production but also reduces cost of cultivation. In this context, the present study has been undertaken to understand the impact of SRI over resource use efficiency and technical efficiency of rice cultivation. Upper velar basin in Salem district of Tamil Nadu was chosen for study as in this area SRI method of rice cultivation is practiced in great extent. The factors influencing the adoption of SRI are also determined. The cost involved in the adoption of SRI is also studied through partial budgeting analysis to show how far SRI is better than conventional rice cultivation practices. It was found that 98 % of SRI farmers are technically efficient against 54 % of the traditional farmers. The study revealed that per hectare cost of cultivation is around five per cent lower in SRI than the conventional method. Moreover adoption of SRI has led to 84 per cent increase in net income than conventional method. Net gain from adopting SRI technology was Rs.17045. It was also found out that SRI ensures farmers' sovereignty by low quantum of water usage, improvement in soil health, decreased in cost of production and low seed requirement.


The development of mathematics' teaching material using project-based learning integrated with science, engineering, and technology (STEM) is a new thing to do. In its development, teaching materials through two series, namely the preparation and development then validation of teaching materials that have been developed. This research was conducted to determine the validity value of mathematics teaching materials based on project integrated with STEM. The data of this study were obtained from the assessment of mathematicians who acted as material experts and media experts to determine the face validation, content validation, and construct validation. The validation by 36 junior high school students was conducted to find out the value of content validity in each part of evaluation to ensure the learning objectives could be achieved. The results of the experts judgement and 36 junior high school students can be concluded that the teaching materials being developed have a high value of face validation, content and constructs. Based on these results, mathematics teaching materials that are developed feasible and valid for use in a broad scope of research or furthermore are worthy of being used in the learning process of teaching mathematics on appropriate topics.


We propose decentralized relay coordination algorithms and corresponding channel state information (CSI) signaling concepts for weighted sum rate maximization, via linear downlink transceiver optimization in multiuser multi-relay MIMO network. Two decentralized algorithms are developed with the local CSI requirements at the base station and the relay nodes. In the first proposed algorithm, the generalized channel inversion precoding is utilized at the base station to avoid the second hop channel sharing requirements among the relay nodes. Further, decentralized transceiver optimization of the relay nodes and users are developed to maximize the weighted sum rate. For the second proposed approach, we provide a novel structure of the precoding matrix of the base station. Then decentralized joint BS, relay and user transceiver design is developed to further improve the performance. Moreover, CSI signaling and decentralized processing in TDD system are analyzed. Simulation results show the effectiveness of the decentralized relay coordination compared to the existing algorithms.


Regnase-1 is an evolutionarily conserved endoribonuclease, degrading diverse mRNAs important, among others, for immune homeostasis, development, and cancer. There are two competing models of Regnase-1 mediated mRNA silencing. One model postulates that Regnase-1 works together with another RNA-binding protein, Roquin-1. The other model proposes that the two proteins function separately. Studying the C. elegans Regnase-1 ortholog, REGE-1, we have uncovered a functional relationship between REGE-1 and the nematode counterpart of Roquin-1, RLE-1. While REGE-1 and RLE-1 associate with mRNA independently of each other, both proteins are essential for mRNA silencing. Intriguingly, the functional interdependence between REGE-1 and RLE-1 is reminiscent of the proposed cooperation between mammalian Regnase-1 and Roquin-1, which may underlie a prototypic silencing mechanism involving both proteins.


We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (eective temperature Te , surface gravity logg, metallicity [Fe=H] and radial velocity Vr) from the rst data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identicati on, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and 4.91 km s 1 in specied eective temperature ranges, for Te , logg, [Fe=H] and Vr respectively. Systematic errors are negligible except for those of Vr. In addition, for stars with PASTEL [Fe=H] < 1:5, the metallicities in DR1 are systematically higher than those in PASTEL.


Rubella usually manifests as a mild, febrile rash.

An effective‐mass model of hydrogenated amorphous silicon (a‐Si:H) is proposed. This model focuses upon the impact of hydrogen on the electronic structure of the tail states. Tail state density‐of‐states calculations are performed in the high hydrogen concentration limit, and the results are found to be in general agreement with present experimental data. These results are shown to be quite robust to variations in the modeling parameters.


Abstract  Background:  Since the advent of cisplatin‐based chemotherapy, the majority of metastatic testicular cancers can be cured by chemotherapy followed by retroperitoneal lymph node dissection (RPLND). However, postchemotherapy RPLND confers no therapeutic benefit if the residual mass contains no viable cells. Therefore, to determine which parameters predict a patient's likelihood of having only necrosis in the residual mass, we retrospectively analyzed clinical parameters of patients who underwent postchemotherapy RPLND.


The group velocity of both acoustic waves and spin waves in crystals are orders of magnitude less than those of electromagnetic waves. As a result, complex analog signal processing tasks that span multiple periods of a signal can be implemented more compactly with acoustic or spin waves than with electromagnetic waves. Acoustic wave devices have thus become common in RF communications circuits, realizing complex linear filter functions in a compact and efficient manner. Although spin-wave-based devices could, in principle, perform many of the same functions as acoustic wave devices, the much higher losses and non-linear effects have limited the practical application of spin wave signal processors. However, we propose that for nonlinear signal processing functions, such as signal correlation, the combination of acoustic and spin wave signals in a single device may prove advantageous. We have developed a magneto-elastic device that exploits the nonlinear interactions between acoustic waves and spin waves to implement a microwave signal correlator. The device, illustrated schematically in Fig. 1a, uses an acoustic wave signal generated by a piezoelectric transducer to parametrically pump [1–3] a signal spin wave launched into a thin-film yttrium-iron-garnet (YIG) waveguide by an antenna. The resulting idler spin wave is picked up by an output antenna. The frequencies of the three waves are related ${{\text{f}}_{p}}={{\text{f}}_{s}}+{{\text{f}}_{i}}$. In our experiments, the acoustic pump signal is at a frequency of $\mathrm {f}_{p}=2.4$ GHz while the signal and idler spin wave frequencies, fs and fi, are a few MHz above and below 1.2 GHz. It can be shown that if the microwave input signal and pump signal are modulated with signals S(t) and P(t) respectively, the generated idler signal is modulated by the combination of the two signals as $\mathrm {I}( \mathrm {t}) = \int _{0 {o}}^{t}\mathrm {S} ( 2 \tau - \mathrm {t}) \mathrm {P}( \tau ) \mathrm {d}\tau $, thus implementing a signal correlator. The correlation time window, to, depends on the length of time that the spin wave transits the pumping region. The correlation signal processing is used to increase the signal-to-noise ratio of weak signals in a presence of an interference. In our proposed scheme the weak signal is used to generate spin-waves via the input spin-wave transducer, while the "reference" code is applied to the pumping acoustic transducer. We created a theoretical formalism, which allows us to predict the characteristics of the output idler signal taking into account the features of the magneto-elastic parametric interactions, magnetic damping and the non-linearities in spinwaves associated with the pumping process. As an example we calculate the distribution of the spin-wave amplitude under the transducer for two orthogonal Walsh codes, while the pumping signal is modulated with one these codes. Fig. 2a demonstrate the distribution of two "signal" spin-waves, while Fig.2b shows the corresponding two "idler" spin-waves under the influence of the the pumping signal. Our simulations show, that i) the output idler power is enhanced when the signal spin-wave code matches the reference and suppressed otherwise, ii) the non-linearity introduced by a relative high pumping amplitude does not spoil the correlation process, and iii) the spinwave damping does not spoil the correlation processing. We have fabricated such a device, and sample results of its operation with a continuous pump are shown in Fig. 1b. The input microwave pulse of duration $\mathrm {t}_{s} \quad =30$ ns on the signal channel generates an idler pulse that appears after some delay at the output. Since the pump is continuous, the output spans a time $\mathrm {t}_{s} + \mathrm {t}_{o}$, where to is approximately 200 ns, the time required for the pulse to traverse the 2 mm long device. We are currently implementing the ability to modulate the pump signal as well, so that the convolution of two signals, such as in Fig 2, can be demonstrated. Such a signal correlator could be used to great advantage at the input to a code division multiple access (CDMA) communications receiver, such as a cellular telephone, to de-correlate the incoming code sequence in the analog domain. Shifting this function to the analog domain could result in significant power savings and may improve the receiver's resilience to interfering signals.


In the proposed paper, we presented a dual-band applicative antenna for satellite communication. According to WARC-92, a band with 13.75-14.0 GHz has been allocated for FSS considering a primary basis. This band covers by our proposed antenna and at the same time, another band which is also a part of satellite communication term as 3-centimeter wave i.e. operating frequency is 10GHz. This band is allocated to amateur radio and satellite use as far as a secondary basis is considered. The antenna size is 35.5x35x0.8mm3and the substrate is Rogers RT-Duroid with relative permittivity (€r) of 2.2. The reflection coefficient| S11| observe at the 10 GHz is -31.43 dB, at the 13.75 GHz is - 18.14dB and at 14.0GHz is -13.8 dB. The bandwidth covered by the first band i.e. 10 GHz is 100 MHz. The second band resonating from 13.2 GHz (lower Ku band) to 14.4 GHz (upper Ku band) under which our required band is easily covered with an ample amount of return loss. The peak gain of 7.642 dB and 6.81 dB is observed at respective bands. The simulation is done with HFSS software.


The search for materials produced from renewable sources aiming at the substitution of petroleum-based derivates is an area of intense investigation. In this work, the enzymatic copolymerization of isosorbide or isomannide with diethyl adipate and fractions of different unsaturated diesters (diethyl itaconate, diethyl fumarate, diethyl glutaconate, and diethyl hydromuconate) were examined using CAL-B as catalyst. The polyesters prepared using one-step syntheses were characterized by SEC, NMR, and MALDI-TOF MS. In addition, syntheses with linear diols were carried out in bulk to evaluate the reactivity of cyclic diols in producing unsaturated polyesters using enzymatic catalysis, as well as to evaluate the occurrence of addition side reactions on the double bonds. Isosorbide and isomannide yielded unsaturated polymers with M¯w values in the order of 4,000-16,000 when fumarate or glutaconate esters were added in 5 mol % ratio against adipate. In all cases MALDI-TOF confirmed the presence of unsaturated units. Although these polyesters have unreacted double bonds they are prone to crosslinking and ready to further functionalization, like anchoring bioactive molecules. © 2013 Wiley Periodicals, Inc. J.

N IH -P A A uhor M anscript N IH -P A A uhor M anscript N IH -P A A uhor M anscript Methods—Latent class models were fit using observations from the 9,039 girls participating in the Growing Up Today Study, an on-going cohort following participants annually or biennially since 1996 when they were ages 9–14 years. Associations between classes and drug use, binge drinking, and depressive symptoms were assessed using generalized estimating equations. Results—Across age groups, there was evidence of six classes: a large asymptomatic class, a class characterized by shape/weight concerns, a class characterized by overeating without loss of control, and three resembling full and subthreshold binge eating disorder, purging disorder, and bulimia nervosa. Relative prevalences of classes varied across developmental stages, with symptomatic classes increasing in prevalence with increasing age. Symptomatic classes were associated with concurrent and incident drug use, binge drinking, and high depressive symptoms. Discussion—A classification system resembling broader definitions of DSM-5 diagnoses along with two further subclinical symptomatic classes may be a useful framework for studying disordered eating among adolescent and young adult females.


Abstract. Given the huge income gap between rural and urban families in China, the rural labor migration plays an important role in increasing rural household income, and thus, reducing inequality in China. Utilizing family-level survey data, we study the effects of family migration rate on family income. Results show that a rural family with 10 percent of the total members migrating to cities for working enjoys a 5.36 percent (or 5.80 percent) higher per-capita income compared with rural counterparts without migrants. Then, the work chooses the proportion of family members having dinner together as the instrumental variable to solve the problem of endogeneity and test the robustness of our estimates. Besides, the work discusses the mechanisms in which migration affects family income and find that remittance is the dominant channel.

Recently, nanomaterials in the world have a very promising potential in the world of technology and industry. One of them is the development of nanocomposite materials. Composite is a combination of two or more different materials, one as a matrix component and the other as a filler component. This study aims to synthesize and characterize Fe3O4/PVDF nanocomposite thin film from natural iron sand using the spin coating method. The thin films nanocomposite magnetite - polyvinylidene fluoride (Fe3O4 - PVDF) was prepared using a solgel method and then developed employing a spin coating device with a mirror substrate. The Fe3O4/PVDF thin film nanocomposite was characterized using XRD and SEM to determine its microstructure. In this paper, the microstructure of Fe3O4/PVDF nanocomposite will be discussed in depth and elaborate the parameters that affect the Fe3O4/PVDF microstructure.


Metsulfuron methyl is an herbicide which has low toxicity and rapidly degraded in the soil, however DuPont stated that it is very poisonous to aquatic organism. Rice husk biochar is commonly used as ameliorants, moreoverit has ability to absorb and degradeharmful chemicals. This study aimed at investigating the effectiveness of rice husk biochar application towards the persistence of metsulfuronmethyl in soil and seepage water. This study applied completely randomized design factorial with two levels of herbicide dose (0 and 300 gr/ha) and four levels of percentage of rice husk biochar(0%, 5%, 10% and 15% of total soil). The results of this research revealed that there was no metsulfuron methyl residue in soil of all treatments after 28 days of herbicide treatment. The residue was found in seepageas much as 7.7 μg/L in treatment of 0% husk biochar and 6.8 μg/L in treatment of 5%husk biochar. The seepage reduced by the increasing of the percentage of rice husk biochar application. Thus, it can be concluded that giving the rice husk biochar is effective for absorbing metsulfuron methyl and preventing it from leaching. However, itcould not hold the presence of metsulfuron methyl longer in soil.


7029 Background: Adjuvant TKI therapy for oncogene addicted cancers is now an established strategy following the FDA approval of imatinib for resected GIST. Given the efficacy of EGFR TKIs in advanced EGFR-mutant lung cancer, adjuvant therapy with EGFR TKIs is also biologically appealing. However, there are conflicting findings to date regarding the potential benefit of adjuvant TKI in patients (pts) with lung cancer harboring EGFR mutations (Janjigian JTO 2010; Goss ASCO 2010) To better understand these results, we studied the natural history of EGFR-mutant lung cancers which recurred despite adjuvant TKI.

METHODS
Pts with recurrent EGFR-mutant lung cancer were identified from an institutional database of pts who received adjuvant/neoadjuvant TKI using an IRB approved waiver. Recurrent cancer specimens, when available, were tested for the T790M resistance mutation. Sensitivity to retreatment with EGFR TKI was evaluated.

RESULTS
23 pts were identified; all cases had an EGFR mutation (61% exon 19 deletion, 35% L858R, 4% other). Pts received adjuvant/neoadjuvant TKI for a median of 19 total months (range 1-39 months); median time to progression (TTP) was 29 months. 8 pts recurred while receiving TKI; 7 of these cases were tested for T790M, which was detected in 4 (57%). 15 pts recurred after stopping TKI (median of 13 months off TKI); however, T790M was not detected in any of the 8 cases tested (p=0.026, Fisher's exact test). 13 pts who recurred after stopping TKI were retreated with a median TTP of 10 months. Radiographic response was seen in 8 of 10 pts (80%); 3 pts had no evaluable disease.

CONCLUSIONS
Pts with EGFR-mutant lung cancer who develop recurrence after stopping adjuvant TKI do not harbor T790M and commonly remain sensitive to TKI treatment. Recurrence of EGFR-mutant lung cancer after adjuvant TKI should not preclude a trial of TKI retreatment; a phase II trial of erlotinib in this setting is underway ( NCT01189435 ). Studies of adjuvant TKI may underestimate the potential benefit for resected EGFR-mutant lung cancers if TKI retreatment at recurrence is not explicitly considered.

Task offloading to edge servers has become a promising solution to tackle the computation resource poverty of the end devices. However, the zero-trust edge computing platform is highly challenged by the growing concern on security and privacy. Thus, Trust Execution Environment (TEE), like TrustZone, is advocated to empower edge clouds to enable secure task offloading. To explore TrustZone, the inevitable involvement of data encryption and decryption operations makes existing offloading strategies not applicable any more, especially when the task dependency is considered. In addition, TrustZone has distinguishable task scheduling paradigm as one CPU core does not allow multitask coexist at the same time. Taking the above issues into consideration, we investigate a dependency-aware task offloading problem for makespan minimization in TrustZone empowered edge clouds. By inventing an extended graph to describe the task execution process, we provide a formal statement to the problem and prove its NP-hardness. We then propose a Customized List Scheduling (CLS) based approximate algorithm and theoretically analyze its achievable performance. Extensive testbed based experiment results show that our approximation algorithm can effectively reduce the makespan and significantly outperforms existing state-of-the-art offloading approaches in TrustZone empowered edge clouds.


It is appropriate to review these two works together, since each is fundamentally addressing the issue of what the authors agree is urgently needed health care reform. However, these authors come at this issue from different perspectives, which are both individually informative and complementary when taken together. As the dust jacket of Arnold Relman's commentary on Rescuing America's Health Care suggests, ''...one of the biggest challenges facing American citizens is our dysfunctional health care system.'' In fact, recent Health and Human Services Secretary Michael Leavitt refused even to call health care in America a ''system.'' He labeled what we have as a health care ''sector'' in search of becoming a ''system''—a truly remarkable statement from a sitting HHS secretary. His hope was that we might actually have an American health care system, perhaps by 2016 or shortly thereafter. Both of these authors, in quite different ways, implicitly address Leavitt's call for creating a health care system that might replace the chaos that characterizes the current health care ''sector.'' Relman is the more recognized of these two physician authors. During his tenure as editor of the prestigious New England Journal of Medicine (NEJM), he achieved worldwide recognition via his many thoughtful editorials, perhaps the most notable of which was his warning about the ''medical-industrial complex,'' echoing President Dwight D. Eisenhower's alarm as he left office regarding the potentially pernicious ''militaryindustrial complex.'' Relman's book represents an expansion of this classic NEJM editorial. In addition, it makes a strong case for abandoning the current financing system of health care, which includes a hodge-podge of privately financed insurance, government programs—such as Medicare, Medicaid, and the military and veterans' health systems— and what often emerges as charity care by local hospitals and physicians for the nearly 50 million Americans with no form of insurance or payment other than their own pocketbooks. What Relman passionately advocates for is none other than the anathema of the health insurance industry and conservative politicians—the dreaded singlepayer system. Yes, speaking from his long perspective as a nationally recognized physician leader, Relman is advocating for ''socialized medicine,'' a form of which people of every advanced Western nation— other than the United States—are entitled, simply because they are citizens of their respective nations. In the body of his book, Relman advances a detailed analysis of what he believes are the pernicious effects of ''the commercialization of U.S. medicine'' and ''the consequences of commercialized care.'' These chapters represent a stinging indictment of for-profit medicine in the United States, a view he has expressed for many years. He then takes on and essentially debunks the notion of ''consumer-driven health care,'' promoted by some academicians and conservative politicians still seeking a ''marketdriven'' approach to solving health care's cost/quality/safety/access issues. He uses these chapters to make the case for why market forces cannot work in health care, and why the United States must turn toward a single-payer system as ''the reform we need,'' the title of his capstone chapter in which he outlines his vision for the future U.S. health care system. He closes with observations on the Canadian health care system (a true ''system,'' by former HHS Inquiry/Volume 46, Spring 2009


In this paper we describe a strategy designed for the synt- hesis of the basic skeleton of furanoeremophilanes, the most abundant class of furanosesquiterpenes. The key steps in the synthetic scheme involve a regio- and stereoselective double alkylation of an enone (tandem vicinal difunctionalization) and construction of the central ring via an intramolecular electrophilic aromatic substitution. To demonstrate this approach, we synthesized the norfuranoeremophila- ne 1 in 8 steps, starting from 2-methyl-2-cyclohexenone and 3-fural-


SUMMARY To define a likelihood we have to specify the form of distribution of the observations, but to define a quasi-likelihood function we need only specify a relation between the mean and variance of the observations and the quasi-likelihood can then be used for estimation. For a one-parameter exponential family the log likelihood is the same as the quasi-likelihood and it follows that assuming a one-paramet'er exponential family is the weakest sort of distributional assumption t'hat can be made. The Gauss-Newton method for calculating nonlinear least squares estimates generalizes easily to deal wit'h maximum quasi-likelihood estimates, and a rearrangement of this produces a generalization of the method described by Nelder & Wedderburn (1972). This paper is mainly concerned wit'h fitting regression models, linear or nonlinear, in which the variance of each observation is specified to be either equal to, or proportional to, some function of its expectat'ion. If the form of distribution of the observations were specified, t'he method of maximum likelihood would give estimates of t'he parameters in t'he model. For instance, if it is specified that the observations have normally distributed errors with constant variance, then the method of least squares provides expressions for the variances and covariances of the estimates, exact for linear models and approximate for nonlinear ones, and these estimates and the expressions for their errors remain valid even if the observations are not normally distributed but merely have a fixed variance; thus, with linear models and a given error variance, the variance of least squares estimat'es is not affected by the distribution of the errors, and the same holds approximately for nonlinear ones. A more general situation is considered in this paper, namely the situation when there is a given relation between the variance and mean of the observations, possibly with an unknown constant of proportionality. A similar problem was considered from a Bayesian viewpoint by Hartigan (1969).We define a quasi-likelihood function, which can be used for estimation in the same way as a likelihood function. With constant variance this again leads to least squares estimation. When other mean-variance relationships are specified, the quasilikelihood sometimes turns out to be a recognizable likelihood function; for instance, for a constant coefficient of variation the quasi-likelihood function is the same as the likelihood obtained by treating the observations as if they had a gamma distribution.

Automation – making a robot perform human functions but without human control – is the overarching goal of robotics. An important aspect of autonomous robots is the ability to detect and avoid obstacles. The goal of this project was to determine the feasibility of enabling a hexapedal robot, known as the EduBot, to generate maps of its surrounding area. This was accomplished by equipping the EduBot with a laser scanner, which was then controlled by the ROS robotic software package. The laser scanner was used to measure the distances to obstacles surrounding the EduBot. These measurements were then used by a ROS program to generate a map of the environment. The EduBot mapped various areas within a building to provide a large sample for analysis. These maps were then compared with the actual area to determine their accuracy. Once software and hardware errors discovered in early maps were corrected, the EduBot was able to generate accurate representations of its surrounding environment, thus allowing the EduBot to sense it surroundings. This suggest that autonomous navigation by the EduBot is possible. 1 Professor, Electrical & Systems Engineering, University of Pennsylvania 2 Post-Doctoral Fellow, Electrical & Systems Engineering, University of Pennsylvania


A prototype of a tail-sitter mini unmanned aircraft (UAV) was developed and subjected to wind-tunnel tests and automatic flight tests. A tail-sitter is an aircraft that takes off and lands on its tail section, with the fuselage pointing upwards. One of the key features of the prototype is that its wing is equipped with leading-edge slats. In previous studies, we conducted wind-tunnel tests and confirmed that the slats increase the stall AoA of the main wing. However, the pitching-trim control force was found to have a poor margin. Automatic flight tests on high-AoA flights with a pitch angle of 60 degrees were not successful because of fluctuations in the pitch attitude caused by the poor effectiveness of the elevators. As a result, the effect of the leading-edge slats was not explicitly confirmed in the flight tests.


This paper motivates a reduced form discrete-time series approach that models realized volatility by using its separated components, continuous variation and variation due to jumps. For this purpose, I combine Engle and Russell's (1998) autoregressive conditional duration (ACD) model applied to the continuous and jump size variation with


Abstract : With currently available space electric power systems, the optimum specific impulse for electrically propelled satellite transfers from low Earth orbit to geosynchronous Earth orbit appears to be in the 1000 to 1200 second range. Arcjets operating with helium as a propellant may be the most efficient electric thruster capable of operating in this specific impulse range. This work reports on a recent set of experiments in which emission spectra of the plume of a helium arcjet were acquired and analyzed to obtain information on the internal energy modes of the arcjet. Of particular interest is the population of electronically excited helium states, as these carry a large energy, and would have a significant negative impact on arcjet performance if highly populated. Experiments were conducted using pure helium as a propellant, and using helium seeded with small amounts (<= 5%) hydrogen. Data are presented which show that the intensity of emissions from the excited helium states falls off rapidly as the hydrogen concentration is increased. Electron temperatures, as determined by Boltzman plots of three different series of helium lines, remain constant within limits of uncertainty as the hydrogen concentration is varied. It is also observed that, as a function of distance from the exit plane, the emission intensities of several lines in the helium spectrum fall off proportionally, indicating that the emission observed does not derive from re-emission of photons originating in the arc which were absorbed by the plume.


An internal sorting algorithm whwh implements a mmimal tree merge strategy is described. It can be used for either strmght merge sorting or natural merge sorting. The number of comparisons is always less than n log2n, ranging from 1⁄2n log2n to n(log2n 1) for straight merge sorting, and from n to n(log2n 1⁄2)for natural merge sorting. The algorithm Is particularly well stated for sorting an unspecified number of Items represented by a linked list, requiring only 2 × (llog2n + 1) extra storage words The sequencing of merges is governed by the lengths of input and intermediate stnngs The heads of ordered strings are maintained m an array which contains two slots for each length range, where a string's length range is defined as [log2 of the length of the strmg. Dunng the first pass of this algorithm, merges are restricted to strings from equal length ranges; a merge is performed whenever a third string for a given length range is created. The second pass merges all remaining strings, starting with the shortest string first. Empn~ical comparisons are presented of straight versus natural merge sorting. Several slmdar algorithms are also discussed.


We study three types of star products in SFT: the ghosts, the twisted ghosts and the matter. We find that their Neumann coefficients are related to each other in a compact way which includes the Gross-Jevicki relation between matter and ghost sector: we explicitly show that the same relation, with a minus sign, holds for the twisted and nontwisted ghosts (which are different but define the same solution). In agreement with this, we prove that matter and twisted ghost coefficients just differ by a minus sign. As a consistency check, we also compute the spectrum of the twisted ghost vertices from conformal field theory and, using equality of twisted and reduced slivers, we derive the spectrum of the non twisted ghost star.

 The present study aimed to compare the main
differences in athlete's motivation related to age, gender, sports, time of practice and competition level. The sample was composed by 385 athletes from different sports, age
between 16 and 30 years. . The MIMCA-BR Questionnaire (Carmo et
al , 2007) was used comparing the motives for beginning and drop-out. Student
"t" test for independent samples was used to compare means (p<0,05) . Significant d ifferences related to gender (in both
scales) was found in the following questions ; "overcome myself" and "to maintain
my shape"; related to the age, "enjoy myself" and "not to obtain the results I
wish" appeared as reasons. Comparing different sports, it was found differences
in "having friends who practice the
sport" and "not materialize dreams as athlete" are more common in team and
individual sports; "hasn't physical conditions" and "hasn' federative support"
are more significant for drop-out in athlete of regional level. It can
be concluded that
there are differences in beginning and drop-out reasons among athletes comparing
gender, age, sports and level of practice. Motivational differences regarding
time of practices had not been found.


Type 2 diabetes mellitus (DM-2) is an important risk factor for the development of heart failure. There are multiple and complex DM mechanisms inducing left ventricular failure. Diastolic disorders are one of its earliest manifestations, characterized by ventricular stiffness associated with the interstitial fibrosis displayed by this disease. Dipeptidylpeptidase-4 (DPP-4) inhibitors are a new generation of drugs used for the treatment of DM-2. These agents inhibit incretin degradation, such as glucagon-like peptide-1 (GLP-1) which stimulates insulin secretion from pancreatic β-cells and also has a direct effect on other organs through the GLP-1 receptor (GLP-1R). The aim of this study was to evaluate the effect of a DPP-4 inhibitor on left ventricular structure and function of leptin receptor-deficient mice that develop obesity and DM-2 as a side effect (Leprdb/db). Treatment with sitagliptin (SITA, a DPP-4 inhibitor) for 8 weeks produced 85% reduction of plasma DPP-4 without evidence of hypoglycemic effects. Analysis of ventricular function from pressure curves obtained by cardiac catheterization showed that SITA treatment does not affect contractility; however, it reduces ventricular stiffness, increases arterial elastance and consequently increases systolic volume. In addition, SITA reduces slightly the increase of interstitial fibrosis. As there is no significant effect of SITA on fibrosis or the collagen type, the improved distensibility must be explained by an extracellular matrix-independent mechanism. For this reason, the authors assessed the passive force/sarcomere length relationship of isolated Leprdb/db myocytes treated with SITA, and compared it with a group not receiving the drug. SITA-treated myocytes significantly reduced stiffness, and significantly increased titin phosphorylation, a sarcomeric protein which participates directly in myocyte stiffness regulation. Thus, 8-week treatment with SITA decreased myocardial stiffness in a DM-2 mouse model and increased systolic output, without modifying blood glucose levels. The mechanism by which DPP-4 inhibition improves diastolic function is still unclear; however, it seems to be mediated by activation of the cGMP-PKG pathway. This novel SITA effect could give rise to new strategies for the treatment of diastolic dysfunction associated with diabetes. mArtÍn DonAto mtsAc


The Torelli group of a genus $g$ oriented surface $S_g$ is the subgroup $\mathcal{I}_g$ of the mapping class group $\mathrm{Mod}(S_g)$ consisting of all mapping classes that act trivially on the homology of $S_g$. One of the most intriguing open problems concerning Torelli groups is the question of whether the group $\mathcal{I}_3$ is finitely presented or not. A possible approach to this problem relies upon the study of the second homology group of $\mathcal{I}_3$ using the spectral sequence $E^r_{p,q}$ for the action of $\mathcal{I}_3$ on the complex of cycles. In this paper we obtain a partial result towards the conjecture that $H_2(\mathcal{I}_3;\mathbb{Z})$ is not finitely generated and hence $\mathcal{I}_3$ is not finitely presented. Namely, we prove that the term $E^3_{0,2}$ of the spectral sequence is infinitely generated, that is, the group $E^1_{0,2}$ remains infinitely generated after taking quotients by images of the differentials $d^1$ and $d^2$. If one proceeded with the proof that it also remains infinitely generated after taking quotient by the image of $d^3$, he would complete the proof of the fact that $\mathcal{I}_3$ is not finitely presented.

The procedures for measuring the plane strain fracture toughness, K{sub Ic}, of metals were originally developed for relatively high yield strength materials, the toughnesses of which were not affected by strain rate. The application of these procedures to lower yield strength and higher toughness structural and pressure vessel steels have since revealed a perplexing combination of problems involving the effects of geometry, stable crack growth and strain rate on the measured values of toughness. Only the geometric problems were encountered in the development of the procedures for measuring K{sub Ic}. For fracture in the linear elastic range of the load-displacement curve, these problems were overcome by specifying specimen dimensions sufficiently large with respect to the plastic zone size at fracture. However, in the case of structural and pressure vessel steels, it is not always possible to test specimens large enough for fracture to occur prior to general yielding. Therefore, in these cases, the effects of large-scale yielding prior to fracture cannot be avoided, but since they presently have no analytical explanation they are being treated empirically. The problems of geometry and strain rate effects on toughness discussed herein are complex and difficult to solve. However, taking advantage of the improvementsmore » that have recently been made in the hardware and software available for performing three-dimensional elastic-plastic and viscoplastic stress analysis, it should be possible to significantly improve the analysis of small-specimen, elastic-plastic fracture toughness data.« less

We present a case of a 49-year-old patient with cardiac tamponade due to haemopericardium. The decision to perform surgery, although controversial, allowed to diagnose cardiac angiosarcoma with metastases to pericardium, vena cava superior and pulmonary trunk. Consequently, chemotherapy was instituted and was initially effective, however, the patient died 12 months later due to the progression of the disease.


The issue of improving the efficiency of customs control, while reducing the additional forms of customs control is the most acute and topical issues of practical activities of customs authorities. The reserves of efficiency of the current risk management system are approaching the specified thresholds if not fully exhausted. Therefore, a fundamentally new approach to risk identification is required to significantly improve the effectiveness of the risk management system. The proposed concept of risk identification and assessment is based on the application of the mechanism of through-process customs control, involving the unification of information about the person being the declarant of goods, as well as the preliminary information about the imported consignment in the amount of information submitted when placing goods under the declared customs procedure with the Declaration of goods. The above features allow to introduce a subject-oriented approach of risk management system at all stages of customs operations in respect of goods imported into the customs territory of the Eurasian economic Union, and also significantly increase the share of formalized risk indicators, including semantic risk indicators, which are the basis for the application of forms of customs control. The introduction of the above risk indicators will ensure the transition to a qualitatively new level of customs control in respect of goods subject to other types of state control and also will lead to a significant increase in the effectiveness of the risk management system by increasing the proportion of identified target risk profiles.

Along the last years a new distributed control system, using smart components and a fieldbus, has been developed and presented in recent DASC conferences. The present application example is the substitution of the conventional central computer aircraft fuel management system, with a new distributed network of smart sensors and actuators, capable of eliminating the need of a central computer. This paper is devoted to recent experimental studies about the performances of the distributed system. In this stage of the research it is interesting to confirm the correct operation of the control system for normal and abnormal fuel system conditions. An important aspect is to take a detailed note of the activity in the fieldbus. Another aspect is to confirm that the dynamic reconfiguration possibilities of the new distributed system, thanks to the smart components, do work in abnormal conditions. The case under study in this paper is more complex than the helicopter case taken initially as reference, now it is an airplane fuel system with six tanks in the wings and a tail tank


The author argues that a deliberate attempt should be made in system design to restrict the coverage of each system to the required area only. This can be done by limitation of transmitter power, limitation of receiver sensitivity, and avoidance of high locations where possible. This would enable more users to talk on each channel in a given geographical area, thus making more efficient use of a radio spectrum which will always be overcrowded. One advantage of VHF is the limited area a base station can cover; escalation of ERP defeats this advantage.


The use of biofuels is justified by the common agricultural policy decisions, by the need to improve environment protection and by the search of alternative energy sources. In such a context, methyl esters of vegetable oils, known as biodiesel and ethyl alcohol are receiving increasing attention as alternative fuels for automotive engines. The main advantages of biodiesel and ethyl alcohol are that these fuels are nontoxic, biodegradable, and renewable with the potential to reduce engine exhaust emissions, especially with regard to greenhouse gases emission. The fact that these biofuels are available in larger and larger quantities is of great importance as well. Currently, in the European market the most important biofuel is FAME (Fatty Acid Methyl Esters) manufactured mainly as Rapeseed Methyl Esters (RME). It is fore‐ casted that the scale of production and consumption of this fuel will continue in‐ creasing as a result of the growing demand for diesel fuels and a levelled demand for spark-ignition engine fuels. Currently, FAME is added to regular diesel fuels in the amount of up to 7%. Besides, its consumption in a pure form grows as well. This chapter presents ecological properties of RME in relation to conventional diesel fuel. The aim of the research was to determine the potential of RME in reducing ex‐ haust emissions (CO, HC, NO x and PM) from diesel engines operated in buses. The tests were carried out in real operating conditions of a city bus meeting EEV emis‐ sions standard. Comparative analysis made it possible to assess the environmental performance of buses depending on the type of fuel used. The obtained results indi‐ cate a slightly lower emission of CO, HC and PM when the vehicle was fuelled with RME but at the same time its application results in a slight increase in the emission of NO x . It seems that similar level of exhaust emissions recorded regardless of fuel type results from an advanced exhaust gas aftertreatment system (SCR + DPF) which was applied in the test vehicle.


Indonesian corporations have been borrowing large sums of money from foreign investors in the past decade, such that private debt ratio has reached 49% of Indonesia's total external debt by the end of 2017. This act of borrowing might improve the borrowing firms' performance which leads to increase in profit, but in other hand it might result on debt value expansion, due to the exchange rate depreciation trend in Indonesia. This paper employs Support Vector Regression, a machine-learning method, to study the relationship between factors that might affect corporate performance, and compares the results with that of the conventional panel data regression method. The study was done using data from annual financial statements of 189 firms in Indonesia during 2011-2017.
It is shown that the machine-learning approach discussed in this study gave better accuracy than the previously employed panel data regression method. Both methods generally showed that balance-sheet effect is more dominant in Indonesian corporations, and it is recommended for companies to minimize their foreign debts and imported purchases, and if possible, export more of their products.


The Closed Circuit Television (CCTV) systems have been used at large scale for tracking and getting popularity with every passing day. The most common goal of CCTV system is prevention of crime and disorder by tracking the objects. The smartphone world is also expanding at a rapid pace since the technology was first introduced. Most users of smartphones live in those countries where usage of CCTV system is part of daily life. This paper studies a tracking system for mobile users based on CCTV system, where information can be sent from mobile to server so that CCTV system can work more specifically and accurately by tracking and recognizing objects. A safety insurance approach is proposed, in which a user can inform his/her location for close observation via CCTV system if he/she feels a potential threat. In case of emergency, location, nature of problem and possible difficulties can be determined in comparatively less time by authorities as they have already monitoring the situation.


In modern conditions the product's life cycle duration is getting short, and changes the rate in the production and logistics technologies all above applies to the logistic material flow of additional requirements. They need to be more flexible with regard quick to tasks and reduction time investment and funds with adaptation to the constantly changing demands on the system. For efficiency and quality rise the analysis and synthesis with complex logistics networks topology is realized by a computer modeling methods for networks with a directed graph that identifies critical path. Effective processes estimation is executed. As the result the algorithm and time amount optimization procedure are considered that takes to move freight from the starting point to the final destination at the specified quality criteria. Algorithm implement realization program in MatLAB codes is constructed. According to the program and algorithm critical path definition example is discussed which is the maximum target functionality is considered.


We propose a new model to describe the $\ensuremath{\alpha}+\ensuremath{\alpha}$ interaction that takes into account the Pauli nonlocality through a velocity-dependent term. With this interaction, we describe very well the phase shifts obtained from elastic scattering data analyses for $\ensuremath{\alpha}+\ensuremath{\alpha}$ at low energies. We also obtain a good description of the $s$-wave resonance related to the $^{8}\mathrm{Be}$ ground-state. The model is based on double-folding procedures and, therefore, it can easily be extended to other systems. We present a test of the model in the case of elastic scattering for $^{4}\mathrm{He}+^{208}\mathrm{Pb}$.

This study explored the feasibility of flexural performance of composite sandwich material composed of various low density polyurethane foam core thickness sandwiched between GFRP skins. The mechanical behaviour of this material was assessed by carrying out a flexural testing. Each spesimen had a nominal dimensions of 110 mm x 30 mm x (c + 4 mm). These spesimens with various core thickness (c) of 2 mm. 5 mm. and 8 mm were then tested in three point bending according to ASTM C 393-00. This study revealed that. by incorporating the thickest core ( 8 mm ) . the bending strength decreases by 42.3 % compared to 5 mm core and it further decreases by 72.6 % compared to 2 mm core. The material stiffness showed positive trend for the thickest core (8 mm). it increases by 53.1 % and 78.1 % compared to 5 mm core and 2 mm core respectively. Low shear modulus of polyurethane foam core contributed to the low bending strength of composite sandwich material with 8 mm core. This was further confirmed by failure analysis under optical microscope which revealed that core shear failure was the dominant failure mechanism for 8 mm core. Meanwhile the dominant failure mechanism for 2 mm core and 5 mm core was microbuckling which confirm the high modulus of GFRP skin. The material stiffness was affected by the high modulus of GFRP skin and the core thickness.


Centrifugal cast HP40Nb alloys are commonly used as ethylene pyrolysis and reformer furnace tube materials. The actual wall temperature can usually reach 1423 K. The technical specifications require that the rupture life shall be at least 120 h under test condition of 1373 K at 17 MPa. The effects of amounts of Lead on the creep and stress rupture performance of the centrifugal cast HP40Nb alloy have been investigated at the temperature of 1373 K and the constant stress of 17 MPa. In this paper, HP40Nb alloy tubes with different contents of Lead element by centrifugal casting were selected, by high temperature stress rupture test and microscopic observation of creep damage, relationship between the content of Lead and high temperature stress rupture lives was given, as well as the threshold value of Lead element. It could provide the basis for ethylene pyrolysis furnace tubes manufacturers and design specifications.Copyright © 2012 by ASME


ally, with all the centralizing tendendes that implies. Yet, while he notes the Nl•"s floundering around the shores of Meech Lake he does not discuss the role played by Bob Rae, Audrey McLaughlin (who is mentioned twice), and the other NI•P leaders who rallied round the government in support of the Charlottetown proposals which were scarcely either anti-Quebec or centralizing in nature. Given the existing profusion oœ writing on the CCF-NHP-sociali:•t theme, Penner might well have devoted much more of his space to arualysis.

The closeness degree describes the fuzzy measurements of sensors,and it plays an important role in the accuracy of information fusion.A consistent and reliable measure is used to describe the fuzzy measurement of the sensor,and a consistent approaching degree fusion algorithm based on particle swarm optimization is proposed.This algorithm establishes a multi-objective and reliable measure of the data model,and the approaching degree between multiple sensors is defined.Using the improved particle swarm optimization algorithm to determine the variety of weights of the model objectively,the ultimate fusion algorithm is given according to the consistent and reliable measurement,and give an example to verify the effectiveness of the algorithm.


Darouach et al (1996) dealt with a method based on the generalized constrained Sylvester equation for the design of reduced order observer for descriptor systems with unknown inputs. New conditions for the existence of reduced-order linear functional state observers for linear systems with unknown inputs were presented by Trinh et al (2004). Systematic procedures for the synthesis of reduced-order functional observers were given. It is stated that the attractive feature of the proposed observer was the simplicity with which the design process can be accomplished. Illustrative examples had been given to illustrate the attractiveness and simplicity of the design procedures.

The pedogenesis and micropedology of seven selected soils from the mid-Jequitinhonha Valley werecharacterized, aiming to identify properties associated with the distribution of soils in the landscape. Podzolswere found on the top of the upper planation surface, closely associated with quartzite and its weatheringproducts. In the bottom of the tectonic depression which forms the mid-valley, soils with low cation exchangecapacity (CEC), low clay activity and presence of stony pavement are found, suggesting a change frompast, humid climate to present-day semi-arid climate. Kaolinitic soils with low Fe-oxides content undersuch regime are thought to represent relicts of former humid climates, being correlatable to the typicalYellow Latosols from the coastal tablelands ("tabuleiros"). In the ill-drained Quaternary plains, soils withhigher sodium contents are found, indicating the imperfect leaching under the present climatic condition.On the top of the regional, late Tertiary surface, deep Latosols occur, associated with saprolites of variouslithologies and Tertiary sediments derived from the erosion of these paleoweathering profiles. In all soils,some micropedological features confirm the polygenetic nature of the soils and landscape of the mid-Jequitinhonha, where either morphogenesis or pedogenesis have dominated, depending on climate,lithological control and tectonic activity .


The concept of Soft Tritopological Space is introduced in this paper, which we defined it over an initial universe with a fixed set of parameters. Also some new definitions of soft open sets in soft tritopological spaces are introduced and investigated, which are called soft -open set, soft -pre-open set, soft -open set (soft tri-open set) and soft -open set. Consequently we can say that the soft tritopological spaces are more comprehensive and generalized than the classical tritopological spaces.

The Takings Clause of the Fifth Amendment, applicable to the states through the Fourteenth Amendment, provides that private property shall not be taken for public use without just compensation. Intangible property rights protected by state law are deserving of the protection of the Takings Clause. The constitutional provision of power to regulate commerce among the several States has also been seen as a limitation on state regulatory powers, even without implementing legislation by Congress. In its negative aspect, the Commerce Clause prohibits "economic protectionism - that is, regulatory measures designed to benefit in-state economic interests by burdening out-of-state competitors". Unlike the Commerce Clause, the Bankruptcy Clause itself contains an affirmative limitation or restriction upon Congress' power: bankruptcy laws must be uniform throughout the United States.Keywords: Bankruptcy Clause; Commerce Clause; economic interests; property rights; substantive protection; Takings Clause


Abstract : This paper summarizes the design, manufacture and evaluation, including cable installation, of dual window (850 nm and 1300 nm) optical fiber cables utilized in the MX missile command control and communication test instrumentation system at Vandenberg Air Force Base. Qualification tests on the finished cables were performed on test equipment especially designed to meet Military Standards DOD 1678. The cables were subjected to impact, tension, compression and low temperature flexibility, while concurrently monitoring optical fiber power levels at 850 and 1300 nm. Temperature cycling, water penetration, water tightness, shock and vibration characteristics of the cables were also obtained. The test equipment employed and the results obtained are discussed herein. (Author)

Haemophilus influenzae is a bacterium that can cause severe infections, occurring mostly in infants and children younger than five years of age. Antibiotic treatment may cause the emergence of resistant H. influenzae strains, particularly ampicillin-resistant strains. Antimicrobial resistance is a public health threat worldwide, particularly in the developing world. H. influenzae strains have been isolated from broncho-alveolar lavages (BALs), nasopharyngeal swabs, and otitis media from children in two paediatric centers at Dakar, Senegal. Antibiotic susceptibility testing was carried out using strips E Test ®t method that provides the ability to precisely determine the minimum inhibitory concentration (MIC). A total of 16 H. influenzae strains have been isolated and identified, including 16.7% of ampicillin-resistant patterns (all β-lactamase-negative), 9.4% of the isolates were resistant to cefaclor (MIC90 = 16 µg/ml) while 100% were susceptible to cefixime to (MIC90 = 0.38 µg/ml). Interestingly, fluoroquinolones were fully active with very low MIC90. Macrolide were still active against H. influenzae isoles although with higher MIC azitrhomycin MIC90= 3µg/ml, clarithromycin MIC90= 12µg/ml. Ampicillin-resistance has become increasingly reported in H. influenzae, suggesting a continuous laboratory based surveillance for antimicrobial resistance pattern for a better management of acute respiratory infections, particularly in low incomes settings.


Attribute reduction can be defined as a process of selecting a minimal subset of attributes (based on a rough set theory as a mathematical tool) from an original set with least lose of information. In this work, a modified great deluge algorithm has been employed on attribute reduction problems, where the search space is divided into three regions. In each region, the water level is updated using a different scheme based on the quality of the current solution, instead of using a linear mechanism which is used in the original great deluge algorithm. The proposed approach is tested on 13 standard benchmark datasets and able to obtain promising results when compared to state-of-the-art approaches.


ASSESSING THE IMPACT OF PRISON SITING ON RURAL ECONOMIC DEVELOPMENT William T. Holley Jr., Ph.D. George Mason University, 2008 Director: Stephen S. Fuller, Ph.D. From 1980 to 2002, the U.S. prison population grew from 330,000 to 1,350,000 inmates. To house these prisoners, hundreds of new prisons were constructed in non-metro counties. Most communities accepted prisons on the promise of new jobs and the hope of economic development, but little research has been done to determine the actual economic development value these institutions provide to the rural counties where they are located. In order to measure the impact of new prisons on the rural economy, this research compares indicators of economic development between non-metro counties with new prisons and similar non-metro counties without prisons. Prisons, as a public good, are limited in their ability to stimulate economic development.


Although bottom-up proteomics using tryptic digests is widely used to locate post-translational modifications (PTM) in proteins, there are cases where the protein has several potential modification sites within a tryptic fragment and MS(2) strategies fail to pinpoint the location. We report here a method using two proteolytic enzymes, trypsin and pepsin, in combination followed by tandem mass spectrometric analysis to provide fragments that allow one to locate the modification sites. We used this strategy to find a glycosylation site on bovine trypsin expressed in maize (TrypZean). Several glycans are present, and all are attached to a nonconsensus N-glycosylation site on the protein.


To solve the problem in diagnosing nitrogen nutrient in rice leaves based on hyperspectral reflectance, we extract weak information from the spectral signal to estimate nitrogen content by applying wavelet analysis to decompose the reflectance spectra.Hyperspectral data were collected in China's northeast city Changchun.The data were used to develop predictive models of nitrogen contents and test the accuracy of the models.We decompose the reflectance and derivative spectra of rice canopy into eight levels using the Db5 function of Daubechies wavelets,and establish 192 models among the obtained wavelet coefficients at different levels and different decomposition positions.By comparison,wavelet coefficients with high precision are selected to establish the best model.The results indicate that wavelet coefficients can be used to obtain accurate prediction of nitrogen content with a high correlation coefficient up to 0.99.The wavelet-based approach outperforms predictive models based on a range of existing spectral indices,showing good prospects in applications for estimating biochemical components of crops that need to extract weak information from hyperspectral data.


Shaping Canberra will generate new national scholarly discussion about the lived experience of Canberra as a place, home and capital. It starts from the position that the local and national dimensions of Canberra are not opposing or even separate aspects, but deeply entwined. On this basis it asks participants to consider how the local, national (and international) play out in instances and reflections of Canberra's life and development in the context of four themes: histories and memories, collections and archives, spaces and places; expressions and interpretations.


Abstract Environmental Education is one of the cross-curricular themes, introduced in the mid 1990s in the curriculum of Flemish secondary education (12-18 yr). Both the Brundtland report and the ENSI philosophy inspired the development of the objectives for EE. A strong partnership exists between the departments of education and the environment of the Flemish Ministry and the provincial authorities, which resulted in the project 'MOS', an environmental management system for primary and secondary schools. Besides environmental objectives, the pedagogical objectives of the project are strongly emphasised. The UN Decade of Education for Sustainable Development provides a strong stimulus to link Environmental Education to the other cross-curricular themes, Citizenship and Health Education and to include the 'MOS'-project into the broader framework of Education for Sustainable Development.

Along with the rapid development of technology, especially on microcontrollers such as Arduino which can be combined with other modules or components to produce new devices that are easy to operate and develop. Arduino is a microcontroller that can be programmed using a programming language, in this study the Arduino microcontroller will be used as the control center to run the DC motor. Arduino will receive commands from the smartphone via a bluetooth connection which will be forwarded to the L298N module to drive the DC motor according to the command received. This study aims to produce a prototype remote control car that can be controlled remotely via a Bluetooth connection as a motion controller in the car. The method used in this research starts from analysis, design, implementation and testing. Tests were carried out to measure the maximum working distance from bluetooth using the HC-05 module.


Abstract Dual frequency (X-band and L-band) synthetic-aperture radar imagery of sea ice is examined to show the differences between the bands and their complementary nature for resolving ambiguities in interpretation. High backscatter at X-band from visibly smooth thin ice is not observed at L-band. One hypothesis is that the high X-band backscatter may be caused by a reflective layer at the snow/ice interface. A second hypothesis is that the high X-band backscatter may be caused by moisture in the snow. A third hypothesis states that the phenomenon may be due to snow flowers. High backscatter at L-band is observed for slush on open water. The return is very weak at X-band, thus allowing distinction of slush by comparing L-band and X-band images. High intensity, but only partial returns from icebergs at L-band have been observed. The hypothesis is that internal iceberg/sea-water reflections are occurring. Some signals are directed away from the antenna, other reinforced signals are returned, producing very bright images. Occasionally, time-delayed signals are returned causing a false image at far range from the iceberg. The conclusion is that L-band is a poor choice for studies of iceberg distribution and size, but a good choice for iceberg detection because of the high reinforced returns from many icebergs and the low return from the adjacent sea ice. The penetration and subsequent signal loss of L-band in glacial ice, when compared to high X-band returns, may be useful to map glacierized land masses.


JoãoAmorim, ULisboa, Lisboa, Portugal, firstname.lastname@example.com ABSTRACT: The increasing use of composites in aircraft industry leads to the need for nondestructive testing systems that are effective in the inspection and evaluation of these structures. Since there is currently a lack of effective systems for inspecting composites, a system that is able to inspect not only composite flat panels but also parts with complex geometries autonomously was developed. This system consists in an instrumented tank that can perform inspections by immersion of complex geometries with a system of five degrees of freedom, which is able to cover a scanning area of approximately 3m 2 . In order to validate the project a flat composite plate, with embedded and previously known defects, was inspected with ultrasonic phased technique, using a LabVIEW program with pre-defined trajectories. This program was developed especially for this system. The final results demonstrate the efficiency the inspection obtained through this system in terms of inspection sensitivity.

MATa cells of Saccharomyces cerevisiae defective in both the SST1 and SST2 gene products exhibit self-arrest when they express the MF alpha 1 gene under the control of the GAL1 promoter. This response to endogenously produced pheromone can be alleviated by mutations which prevent the production of, or response to, alpha-factor. Suppressors of the self-arrest phenotype include a class of mutants which remain responsive to low levels of pheromone, but are resistant to high levels of alpha-factor. One of these mutants has been mapped to chromosome X, 31 cM distal to SUP4, and defines a new locus designated STE18.


We demonstrate that for quantum dot (QD) based electrochemiluminescence (ECL), the commonly used co-reactant does not perform as effectively as potassium persul-fate. By exploiting this small change in co-reactant, ECL intensity can be enhanced dramatically in a cathodic-based ECL system. However, TPA remains the preferential co-reactant-based system for anodic ECL. This phenomenon can be rationalised through the relative energy-level profiles of the QD to the co-reactant in conjunction with the applied potential range. This work highlights the importance of understanding the co-reactant pathway for optimising the application of ECL to bioanalytical analysis, in particular for near-infrared (NIR) QDs which can be utilised for analysis in blood.


Matching markets have historically been an important topic in economics research. On the positive (descriptive) side, researchers have modeled everything ranging from marriage markets to labor markets using the framework of matching. Matching was also one of the first areas in which market design made a name for itself, perhaps most famously in the redesign of the market that matches graduating M.D.s to their first residency programs in the United States. The arrival of computer scientists to the field of market design in general can be traced to many of the reasons suggested recently by Conitzer [2010] (in a broader context than just market design) in an article in Communications of the ACM, including the effects of new markets that have been made possible by advances in networking and Internet technology, a more computational mindset in general, and also the ability to view problems from a different perspective. In the case of matching markets in particular, in addition to the (often) constructive nature of computational approaches, there is also the historical fact that computer scientists have studied matching from many different perspectives, perhaps because matching markets have a very natural representation in the language of graphs.
