The purpose of this study was to develop resource materials to assist non-music specialist primary teachers with the integration of Newfoundland folk songs into other primary curriculum areas. The materials were developed and entitled Hello Newfoundland. They consist of an audio-tape recording of eleven traditional Newfoundland folk songs for young children and a companion teacher's guidebook, focusing on the integration of these songs with other areas of the primary curriculum. -- The guidebook, Hello Newfoundland, was then presented to sixteen primary teachers representing Kindergarten through Grade Three. The teachers were invited, by completing a questionnaire, to assess the potential these resource materials would have for use by generalist primary teachers. Their reactions were sought specifically regarding the Newfoundland content of the materials, the suggested activities in the guidebook, the overall quality of the materials and the potential of the materials for use in primary classrooms by non-music specialist teachers. -- The findings of this study indicate that with regard to each of these categories, the general response of teachers was, extremely positive and encouraging.


Infrared spectroscopy has long been a powerful analysis tool in the laboratory. Only recently, however, has it moved from the lab into the field or onto the industrial process line. Conventional spectroscopic methods often involve equipment (e.g., delicate long-pathlength cells) or sample-preparation methods (e.g., grinding and dilution) that are difficult to use outside the laboratory. In our project we use two unconventional techniques requiring no delicate equipment and little or no sample preparation to bring the capabilities of infrared spectroscopy out of the laboratory or to materials that are difficult to handle. The techniques are photoacoustic spectroscopy (PAS) and transient infrared spectroscopy (TIRS). We use PAS to acquire infrared spectra of volatile organic compounds (VOCS) in air, water, and soil samples in the field, so that the VOCs may be identified and their concentrations measured. PAS is also being used in the laboratory to examine radioactive materials, because it requires very little sample handling and minimal sample volume. TIRS is an on-line technique for acquiring the infrared spectra of solids and viscous liquids. It is being developed as a real-time monitor for the polyethylene encapsulation of radioactive wastes that is being developed at Brookhaven National Laboratory and being tested atmore » Rocky Flats Plant. These three applications of PAS and TIRS are discussed in detail below.« less


THE doctrine of the Persistence of Force, as it is among the latest, 80 it is considered among the surest and the most important of the results of modern science. Like e"\"'ery other advance in truth, it must needs ilave interest to the theologian; but, in the absorbing attention given to its physical relations, its theological bearings have not yet been sufficiently considered. A. certain vague recognition of the constancy of force, of a relation between the different physical forces, and, specifically, a suspicion, at least, that heat is " a mode of motion" among the particles of matter, may be found occasionally among the older philosophers. Witb them it was but a vague guess, like many others, which, in the minds of those familiar with nature, often become prophecies of future discovery. The matter was first brought to definite experimental test by Count Rumford at the close of the last century. He established the convertibility of mechanical motion into heat, and even determined, with a fair approximation to accuracy, the mechanical equivalent of heat. A little later these conclusions were confirmed by the experiments of Davy; but after this the subject was suffered to rest for nearly half a cenVOL. xxxvm No. 149. -JANUARY, 1881. 1


There are great demands for talents of ASEAN languages, with the permanent settlement of China-ASEAN Expo in Nanning, the opening and development of Guangxi Beibu Gulf Zone up to national development strategy and the completion of China-Sean Free Trade Zone. However, inferior talents cannot meet the market needs in spite of universities'expanding enrollment in Guangxi. Guangxi Dongfang Foreign Language College has initially established a mode of "Double-Track Mechanism", and has explored a new approach to cultivating senior talents of ASEAN languages in Guangxi. It will be a great honor to give some enlightenment for fellow colleges.


Early contractor involvement is a topic that has attracted attention from construction practitioners and researchers in the UK since the 1990s. It has been adopted to introduce construction knowledge and experience to the design process, and to integrate design with construction. In contrast with the limited number of previous studies on early contractor involvement, which used case studies, a questionnaire survey was conducted in this study, to investigate the application of early contractor involvement in current practice and its impact on project performance in terms of time, cost and quality. From an analysis of the questionnaire results, early contractor involvement is found to be increasingly used in the construction industry, and to have a significant impact on cost and time performance. This research provides empirical evidence related to the practice of early contractor involvement. It demonstrates the major influence of early contractor involvement on management processes and working relationships during a project, which contribute to performance improvement and project success.


The appropriate representative temperature in apparent specific heat measurement is investigated herein using a thermal conductivity analysis. The representative temperature is used when the apparent specific heat is calculated from the temperature and heat flux time series data. Using the weighted average temperature of the surface temperature of the Phase Change Materials (PCM) specimens and the temperature between two specimens as the representative temperature appears appropriate. The appropriate rate of the temperature between the specimens is affected by thermal conductivity, latent heat, temperature change rate, and, in particular, the temperature range of the phase change; it should be 0.7–1.0. This study investigates an appropriate representative temperature in an apparent specific heat measurement of Phase Change Materials (PCM) through a thermal conductivity analysis. The representative temperature is used when apparent specific heat is calculated from the temperature and heat flux time series data, which affects the apparent specific heat result. studies established experimental methods of present study thermal conductivity analysis specific measurement is used. A total of 27 types of PCM with several levels of thermal conductivity, latent heat, and temperature range of phase change are examined. An index of the ratio of the central temperature (i.e., temperature between two flat PCM specimens) is defined for the examination. This index is used to calculate a weighted average temperature of the PCM from the surface and central temperatures. Further, the apparent specific heats are calculated from the surface and central temperatures and the ratio of the central temperature for each PCM to verify the measurement accuracy. The calculated apparent specific heats are compared with the accurate apparent specific heats input into the calculation.


The effect of gibberellic acid (10 -4 M) on the incorporation of 8- 14 C adenine, 3 H phenylalanine, the dimensions of mitotic cells and the durations of particular stages in the cell cycle were studied in synchronously dividing cells of the antheridial filaments in Chara vulgaris L. during succesive periods of growth and differentiation. GA 3 strongly stimulates the uptake of both labeled precursors in the course of a whole interphase and in all generations of the antheridial filaments; approximatively in proportion to the intensity of the process in the control. The gibberellin causes a slight increment in cell dimensions and strongly reduces the cell cycle durations: the S, G2, and M to a similar degree. The earlier is the generation of the antheridial filament, the more pronounced is the influence of the plant growth substance. Since the gibberellin stimulated the course of all examined processes, the present study did not reveal any stage of interphase to be especially sensitive to GA 3 . The results suggest to interpret the effect of GA 3 as an unspecific stimulator of metabolism in cells of the antheridial filaments of Chara vulgaris L.

Secondly, there are many immanent and interlocking styles in hotel's architectural block plans, many composition styles in big sized hotels, in opposition immanent styles in small sized ones and there are many trend of concourse style in medium sized hotels. To the layout of hotel's room inside of the linear styles are many in big and medium sized hotels.


In the last decade, gamification has become one of the teaching-learning strategies that has received the most attention in the world of education. This new tool uses the elements of the games to design experiences that attract the attention of students, increase their interest and motivation, and improve their learning results. Nevertheless, despite the potential of gamification, teachers are faced with the difficulty of fusing curricular elements with gamable elements to achieve an effective educational experience adapted to the curricular level of students. For this reason, the present chapter aims to design a didactic proposal of gamification destined to work with contents of physical education in the pre-school stage. This chapter shows that gamification can be used in the field of early childhood education without the need to use a large amount of educational resources, if teachers have knowledge about the process to be followed to adapt the curriculum.


A model study for the enantioselective total synthesis of γ-rubromycin has revealed a promising approach for constructing the chiral, nonracemic bicyclic spiroacetal via the stereospecific photoredox reaction of 1,2-naphthoquinone ether.


Constituents with linear radiance gradients with concentration may be quantified from signals which contain nonlinear atmospheric and surface reflection effects for both homogeneous and non-homogeneous water bodies provided accurate data can be obtained and nonlinearities are constant with wavelength. Statistical parameters must be used which give an indication of bias as well as total squared error to insure that an equation with an optimum combination of bands is selected. It is concluded that the effect of error in upwelled radiance measurements is to reduce the accuracy of the least square fitting process and to increase the number of points required to obtain a satisfactory fit. The problem of obtaining a multiple regression equation that is extremely sensitive to error is discussed.


In the present investigation, we will derive sufficient conditions for starlikeness of meromorphic m -valent functions in the punctured disc.


In the 1990s the banks established in the Italian South have reduced their cost-income ratios and improved their ability to screen customers, increasing profitability. The spread between the loan rates in the South and North has narrowed substantially. Taking into account differences in the size and industry composition of firms in the two areas, the spread is currently equal to 0.90 percent. The growth of loans in the North has outpaced that in the South, but this divergence is merely a reflection of the greater proportion of new bad loans in relation to total lending in the South. Since the mid-1990s in the South the ratio of loans to local firms to funds raised locally has increased from 75 to 85%. The lower value of the ratio in the South reflects structural features of the Southern economy and the way in which loans are allocated geographically in financial statistics.

We found a significant positive correlation between local summer air temperature (May-September) and the annual sediment mass accumulation rate (MAR) in Lake Silvaplana (46°N, 9°E, 1800 m a.s.l.) during the twentieth century (r = 0.69, p < 0.001 for decadal smoothed series). Sediment trap data (2001-2005) confirm this relation with exceptionally high particle yields during the hottest summer of the last 140 years in 2003. On this base we developed a decadal-scale summer temperature reconstruction back to AD 1580. Surprisingly, the comparison of our reconstruction with two other independent regional summer temperature reconstructions (based on tree-rings and documentary data) revealed a significant negative correlation for the pre-1900 data (ie, late 'Little Ice Age'). This demonstrates that the correlation between MAR and summer temperature is not stable in time and the actualistic principle does not apply in this case. We suggest that different climatic regimes (modern/'Little Ice Age') lead to changing state conditions in the catchment and thus to considerably different sediment transport mechanisms. Therefore, we calibrated our MAR data with gridded early instrumental temperature series from AD 1760-1880 (r = -0.48, p < 0.01 for decadal smoothed series) to properly reconstruct the late LIA climatic conditions. We found exceptionally low temperatures between AD 1580 and 1610 (0.75°C below twentieth-century mean) and during the late Maunder Minimum from AD 1680 to 1710 (0.5°C below twentieth-century mean). In general, summer temperatures did not experience major negative departures from the twentieth-century mean during the late 'Little Ice Age'. This compares well with the two existing independent regional reconstructions suggesting that the LIA in the Alps was mainly a phenomenon of the cold season.

We present results from calculations of different quark number and hadronic susceptibilities on 2+1-flavor dynamical domain wall ensembles. We find that the iso-spin and electric charge sus-ceptibilities are especially well suited to determine the transition temperature, as these quantities show only small statistical errors. Moreover, the transition values of the coupling obtained from iso-spin and electrical charge susceptibilities are in good agreement with the one obtained from the chiral condensate.

Background Traditional biomechanical evaluations of rotator cuff repair techniques employ cyclic loading of the supraspinatus tendon in an isolated medial direction. Purpose This study was conducted to evaluate 2 different rotator cuff repair techniques that are currently the subject of debate with cyclic loading and with internal and external humeral rotation to better simulate postoperative rehabilitation. Study Design Controlled laboratory study. Methods Nine fresh-frozen paired human cadaver shoulders (18 shoulders) were studied. A single-row repair with 2 suture anchors was compared with a double-row repair with 4 suture anchors. The shoulders were tested in a custom device to position the shoulder in neutral, 45° of internal rotation, and 45° of external rotation. Cyclic loading of the supraspinatus tendon was performed with an MTS material testing machine. Gap formation was measured and analyzed for each rotational position using the MTS device. Results For the single-row repair, average gap formation per 100 cycles in the positions of neutral, internal, and external humeral rotation was 1.47 ± 0.63, 3.11 ± 1.55, and 2.24 ± 0.94 mm, respectively. For the double-row repair, average gap formation per 100 cycles in the positions of neutral, internal, and external humeral rotation was 1.25 ± 0.54, 2.29 ± 1.10, and 1.57 ± 0.48 mm, respectively. For gapping averaged over all positions, the double-row repair had significantly less gapping than the single-row repair (P = .0109); gapping was greatest for internal rotation, followed by external rotation, and least for neutral (P < .0001). Conclusion The testing method of including a rotational component in biomechanical rotator cuff repair testing is a more realistic model of the loading conditions experienced by a repaired rotator cuff as the patient participates in postoperative rehabilitation. Double-row repair has better fixation strength than single-row repairs when exposed to cyclic loading and changes in humeral rotation position. Clinical Relevance Humeral rotation affects rotator cuff fixation and should be considered in postoperative rehabilitation.


: This study aims to provide evidence to support the development of automated vehicle (AV) safety assessments that consider the possible presence of non-motorized vulnerable road-users (VRUs) on limited-access highways. Although limited-access highways are designed to accommodate high-speed motor vehicles, collisions involving VRUs on such roadways are frequently reported. A narrative review is conducted, covering the epidemiology of VRUs crashes on limited-access highways to identify typical crash patterns considering collisions severity and the underlying reasons for the VRUs to use the highway. The review results show that occupants alighting from a disabled or crashed vehicle, people seeking help or helping others, highway maintenance zones, police stops, and people crossing a highway should be given priority to ensure VRU safety on limited-access highways. The results are summarized in figures with schematic models to generate test scenarios for AV safety assessment. Additionally, the results are discussed using two examples of traffic situations relevant to the potential AV-VRU crashes on highways and the current performance of autonomous emergency braking and autonomous emergency steering systems. These findings have important implications for producing scenarios in which AV may not produce crashes lest it performs worse than human drivers in the proposed scenarios.


Tasmania has a temperate climate well-suited for hemp production, is located nearer to the south pole than other regions of Australia, and therefore presents an important location for hemp variety trials. The primary aim of this research is to evaluate the performance of hemp (Cannabis) fiber and seed cultivars from various geographical origins and latitudes when grown in southern Tasmania. Seventeen registered hemp cultivars were sown on three dates in large replicate trial blocks to allow combine harvesting and collection of accurate yield data. Results are discussed with respect to site selection, crop performance, sowing dates, sowing rates, crop development, pest infestation, THC levels, seed yields, crop management and cultivar selection. Canadian cultivars performed well for grain seed production with the highest yields and their short crop height accommodates mechanical harvesting. French cultivars yielded much less seed than Canadian cultivars and grew to heights nearly beyond the reach of a standard grain header. Chinese cultivars flowered too late to produce viable seeds and are not suitable for hemp seed grain production in Tasmania, although their vigorous growth and late flowering makes them good candidates for biomass production. THC levels in the sampled Chinese cultivars were too high for seed production, but those that do not flower at Tasmanian latitudes are suitable for fiber and biomass production.

The invention discloses a processing method and a system capable of achieving one machine supporting high concurrency. The processing system capable of achieving one machine supporting high concurrency comprises an information receiving queue, a main thread and a worker thread which are located on a same server. After the main thread monitors an event, the main thread judges event type. When the event type is a newly connected event of a client end, a new socket is received and processed. When the event type is a transmission request event, a transmission request instruction is received, request information is generated and added to the information receiving queue according to the instruction; when the event type is an output event, data in a send state is sent; and the worker thread reads the request information of the information receiving queue, obtains response data of the request information and set the response data to be a sent state. A stand-alone system is enabled to support concurrent access of more users, distributed cluster deployment is not needed, the framework is simple, and whole cost is low.


Summary Long-term administration of prednisolone to BALB/c mice alters the reactivity of their lymphoid tissue to the oncogenic effects of Moloney leukemia virus. Solid lymphosarcoma or granulocytic leukemia is produced in a significant number of the treated mice. The alteration in disease response may be attributed to a prednisolone-induced simulated thymectomy.


The fuel for diesel engines must meet several goals: to ensure a safe and fast engine start at any environmental temperature, to allow a safe operation of the engine with a yield as high as possible, to burn completely without producing harmful substances for human health, not to act in a corrosive way on the metals, to allow the transport, storage and distribution to the customer without difficulties, while maintaining the properties. In this sense, the purpose of the experimental research has been to determine the combustion characteristics of the experimented fuels (cetane number, ignition delay, the start of the main combustion, the combustion period, the maximum positioning of the speed of released heat).


Abstract : The Industrial Operations Division (SEPD), Systems Engineering and Production Directorate (SEPD), AMCOM has the mission and function of providing microelectronic technology assessments, and producibility and supportability analyses for AMCOM weapon systems. IOD evaluates the impacts of nonavailability of microelectronic parts on the life cycle supportability of the AMCOM weapon systems and evaluates the producibility of AMCOM weapon systems. IOD required engineering support in performing microelectronic technology trend assessments for several AMCOM systems and in assessing the impact of nonavailability on those systems. The Systems Management and Production Laboratory at UAH was tasked to provide this engineering support and analytical capability.


Microcomputers and their users rely on interconnects to communicate. At the Hot Interconnects 10 conference, which took place 21 to 23 August 2002 at Stanford University, designers and architects from universities and companies met to discuss new technologies for high-performance switches, routers, and packet processing engines. These technologies enable computers and users to seamlessly exchange data over the Internet. They also transport data between multi-processors, interconnect clusters of workstations, and implement the core switching in storage area networks.


Short term load forecasting (STLF) is a fundamental component of demand response programs in smart grids. Recent literature has focused on complex neural networks and deep learning models for solving STLF. While these models work well for load forecasting with complex non-linear relationships, they have been shown to be less effective than simpler univariate models for STLF problems with under a 6 hours horizon. Given the lack of multivariate data (such as temperature) in many practical datasets, we need better univariate prediction models for STLF. By partitioning the dataset by temporal features, we develop a novel ensemble learning method that exploits daily seasonality in electricity consumption data to improve accuracy of popular univariate models. We train an ensemble of models from the dataset partitions. We develop a variety of methods, including Ridge Regression, to increase the robustness of the ensemble prediction. To show the effectiveness of our approach, we perform detailed evaluation using an aggregated user electricity consumption dataset collected by the Los Angeles Department of Water and Power (LADWP). We select four popular prediction algorithms in literature for our experiments, including Kernel Regression (KR), Support Vector Regression (SVR) and neural network approaches. We compare the performance of these algorithms applying our ensemble approach to training only one single model. Our approach leads to an 11.2% decrease in mean absolute percentage error (MAPE) and 21.3% decrease in root mean squared error (RMSE) over the single model approach for KR, and a 30% and 32.4% decrease in MAPE and RMSE respectively for SVR. These ensemble models also outperform the neural network approaches.


3 Abstract: The unprecedented increase in usage and dependence on the internet, has led to a flood of security attacks on computing infrastructure. Moreover, the attacks are also becoming more and more sophisticated. Even though wide varieties of IDS are available today, they are unable to address challenges that surround different types of attacks. Most of these IDS are designed to handle specific types of attacks. It is evident that no single technique can guarantee protection against future attacks. Hence there is a need for integrated architecture which can provide robust protection against a complete spectrum of threats. In this paper, we propose an architectural design based on the service oriented paradigm for building intrusion detection systems.


The 2011 Tohoku-oki earthquake (Tohoku Earthquake: Mw 9.0) caused over 50 m coseismic slip. After then many geodetic observations such as on-shore GNSS, GPS/Acoustic (GPS/A), and others, have been carried out. Especially, GPS/A played important roll to reveal large off-shore coseismic displacement and subsequent postseismic deformation, which can be interpreted by viscoelastic relaxation (Sun et al., 2014, Nature; Watanabe et al., 2014, GRL; Tomita et al., 2015, GRL) and/or afterslip. Because GPS/A observation alone cannot reveal the afterslip of megathrust in the shallow dip of the trench, "direct-path acoustic ranging", which can measure precise relative distance (e.g., ~ mm/yr precision for 1 km baseline) between two stations, was used across the trench. It periodically measures two-way travel-time and is corrected the calculated sound velocity after the recovery. Prior to this study, the same observations were conducted twice; they were 2013 (~150-days) (Osada et al., 2014, JpGU) and 2014-2015 (~250-days) (Yamamoto et al., 2016, JpGU), respectively. These observations proved the capability to measure as long as ~10 km baseline and found no significant relative motion across the trench. In September 2015, we installed five instruments at the same, the region of large coseismic slip (e.g., Iinuma et al., 2012, JGR) and recovered in September 2016 (~360-days observation). The result shows no significant movement across the trench axis like as in the previous surveys. This result shows fully locked state and may clarify the absence of postseismic slip in the shallower part in this area and at least 2013-2016. In March 2017, we plan to install five instruments across the Japan Trench off-Fukushima, where instead large postseismic slip (e.g., Sun and Wang, 2015, JGR; Iinuma et al., 2016, Nature Comm.). This auxiliary observation may reveal spatial variation of convergence rate along the trench axis. Acknowledgement: This observation is supported by JSPS KAKENHI (26000002). The installation and recovery of the instruments were carried out during the KAIREI (KR15-15) and SHINSEIMARU (KS-16-14) cruises.


Three types of optimal, continuously time-varying sliding mode for robust control of second-order uncertain dynamic systems subject to input constraint are presented. Two of the modes incorporate straight sliding lines, and the third uses the so-called terminal slider, that is a curve that guarantees system error convergence to zero in finite time. At first, all three lines adapt themselves to the initial conditions of the system, and afterwards they move in such a way that, for each of them, the integral of the absolute value of the systems error is minimised over the whole period of the control action. By this means, insensitivity of the system to external disturbances and parameter uncertainties is guaranteed from the very beginning of the proposed control action, and the system error convergence rate can be increased. Performance of the three control algorithms is compared, and the Lyapunov theory is used to prove the existence of a sliding mode on the lines.


An $(a:b)$-coloring of a graph $G$ is a function $f$ which maps the vertices of $G$ into $b$-element subsets of some set of size $a$ in such a way that $f(u)$ is disjoint from $f(v)$ for every two adjacent vertices $u$ and $v$ in $G$. The fractional chromatic number $\chi_f(G)$ is the infimum of $a/b$ over all pairs of positive integers $a,b$ such that $G$ has an $(a:b)$-coloring. Heckman and Thomas conjectured that the fractional chromatic number of every triangle-free graph $G$ of maximum degree at most three is at most 2.8. Hatami and Zhu proved that $\chi_f(G) \leq 3-3/64 \approx 2.953$. Lu and Peng improved the bound to $\chi_f(G) \leq 3-3/43 \approx 2.930$. Recently, Ferguson, Kaiser, and Kral' proved that $\chi_f(G) \leq 32/11 \approx 2.909$. In this paper, we prove that $\chi_f(G) \leq 43/15 \approx 2.867$.


PURPOSE
Accuracy of a RSP-HU calibration curve produced for proton treatment planning is tested by comparing the treatment planning system dose grid to physical doses delivered on film by a Mevion S250 double-scattering proton unit.

METHODS
A single batch of EBT3 Gafchromic film was used for calibration and measurements. The film calibration curve was obtained using Mevion proton beam reference option 20 (15cm range, 10cm modulation). Paired films were positioned at the center of the spread out Bragg peak (SOBP) in solid water. The calibration doses were verified with an ion chamber, including background and doses from 20cGy to 350cGy. Films were scanned in a flatbed Epson-Expression 10000-XL scanner, and analyzed using the red channel. A Rando phantom was scanned with a GE LightSpeed CT Simulator. A single-field proton plan (Eclipse, Varian) was calculated to deliver 171cGy to the pelvis section (heterogeneous region), using a standard 4×4cm aperture without compensator, 7.89cm beam range, and 5.36cm SOBP. Varied depths of the calculated distal 90% isodose-line were recorded and compared. The dose distribution from film irradiated between Rando slices was compared with the calculated plans using RIT v.6.2.

RESULTS
Distal 90% isodose-line depth variation between CT scans was 2mm on average, and 4mm at maximum. Fine calculation of this variation was restricted by the dose calculation grid, as well as the slice thickness. Dose differences between calibrated film measurements and calculated doses were on average 5.93cGy (3.5%), with the large majority of differences forming a normal distribution around 3.5cGy (2%). Calculated doses were almost entirely greater than those measured.

CONCLUSION
RSP to HU calibration curve is shown to produce distal depth variation within the margin of tolerance (±4.3mm) across all potential scan energies and protocols. Dose distribution calculation is accurate to 2-4% within the SOBP, including areas of high tissue heterogeneity.


Abstract By the determination of birefringence and elongation at break as functions of the distance from the surface detailed informations are obtained about the states of orientation of the molecules in injection molded polypropylene plates. Both, the birefringence profile and the profile of elongation at break in the cross-section of the plates, exhibit the skin/core structure typically for injection molded polypropylene articles. An analysis of the results of two polypropylene grades molded at different processing conditions shows a good agreement of both methods.


Thumb sucking is a behavioral habit disorder. Thumb sucking is considered as a normal developmental phase but may become a habit in some children. It can be due some insecurities, boredom, and loneliness experienced by the child and may develop after the birth of sibling. Persistent sucking of thumb or fingers in older children is a cause of concern as it may lead to dental malocclusion, soreness of fingers or thumb, and speech difficulties. Homoeopathy offers effective and safe treatment for thumb sucking in children. In this article an attempt is made to explain thumb sucking in children and its homoeopathic management.

Keywords: Thumb sucking, Children, Homoeopathy, Habit disorder.

This report investigates the effect of the negative enantiomer of 1-hydroxy-3-aminopyrrolidone-2 (HA-966) on behavioral and biochemical changes elicited by pharmacological or experimental paradigms which activate mesocorticolimbic dopaminergic neurotransmission. Several paradigms were used, including cocaine sensitization and two stressors: restraint for 30 min and an aversive conditioning model. (S)-(2)-HA-966 (3 and 5 mg/kg i.p.) prevented restraint stress-induced dopamine utilization in both the medial prefrontal cortex and nucleus accumbens, in contrast to the positive enantiomer. Conditioned fear increased dopamine metabolism in both the core and shell subdivisions of the nucleus accumbens, an effect blocked by (S)-(2)-HA-966. The conditioned stress-induced increase in dopamine metabolism in the medial prefrontal cortex was also blocked by (S)-(2)-HA-966. In addition, (S)-(2)-HA-966 suppressed fear-induced behaviors: immobility and defecation. In other studies, (S)-(2)-HA-966 (3 mg/kg i.p.) prevented locomotor sensitization without altering the acute motoric response elicited by cocaine. The highest dose of (S)-(2)-HA-966 (5 mg/kg i.p.) blocked acute cocaine-induced locomotion but resulted in sedation. In addition, the highest dose of (S)-(2)-HA966 tested suppressed weight gain in control rats, unlike its enantiomer, (R)-(1)-HA-966. Because (S)-(2)-HA-966 has been proposed to act at the g-aminobutyric acid (GABA)B receptor, we examined the ability of (S)-(2) and (R)-(1)-HA-966 to displace [H]-(2)-baclofen from cortical membranes to assess GABAB receptor binding. Neither enantiomer significantly altered [H]-(2)-baclofen binding at relevant concentrations, indicating the actions of (S)-(2)-HA-966 reported here are the results of a mechanism apparently independent of the baclofen binding site on the GABAB receptor. The pharmacological, physiological and behavioral properties of (6)-HA-966 have been widely documented in the past. As a heterocyclic imido five-member ring, (6)-HA-966 appears to be structurally similar to a cyclic form of GABA. Bonta et al. (1971) observed that racemic HA-966 had sedative qualities that mimicked the behavioral properties of gHB. Furthermore, it was found that after the administration of (6)-HA-966, DA levels were increased in the striatum of the rat brain (Bonta et al., 1971) and the spontaneous firing rate of substantia nigra dopaminergic neurons was reduced in a dose-dependent fashion (Nowycky and Roth, 1977; Shepard and Lehmann, 1992), actions similar to those noted with gHB (Roth et al., 1977). In contrast to these findings, Davies and Watkins (1972) discovered that (6)-HA966 was an excitatory amino acid antagonist, later discovered to act through the glycine modulatory site of the NMDA receptor (Foster and Kemp, 1989). Only after the enantiomers of (6)-HA-966 were resolved, however, was it possible to attribute the unique characteristics of the racemic compound to its components. Radioligand binding and electrophysiological studies demonstrated that the antagonistic effects of (6)-HA-966 on the glycine/NMDA receptor mainly resided in the (R)-(1) enantiomer, whereas behavioral studies indicated that the sedative/ataxic properties of (6)-HA-966 were primarily due to the (S)-(2) enantiomer. The effects of the racemic compound on nigrostriatal DA neurons seem to reside with the (S)-(2) enantiomer, including increased striatal DA levels (Singh et al., 1990) and Received for publication March 7, 1997. 1 This work was supported by United States Public Health Service Award MH14092.

The simultaneous blockade in spontaneous firing with diminished release and continued synthesis of DA in striatal dopaminergic neurons has been used to explain the increases in striatal DA levels attributed to (2)-HA-966 (Singh et al., 1990). Increased striatal DA levels, as well as the sedative behavioral properties, were noted to mirror those seen with gHB and g-butyrolactone (Roth et al., 1977), both of which are structurally similar to (6)-HA-966 (Bonta et al., 1971; Singh et al., 1990). It was postulated that (2)-HA-966 exerted its effects through the GABAB receptor based on the resemblance of HA-966 to the cyclic form of GABA and because gHB has been proposed to elicit its actions through the GABAB receptor (Engberg and Nissbrandt, 1993). In support of this, the GABAB antagonist CGP 35348 was found to attenuate the increase in DA synthesis by g-butyrolactone, HA-966 and the GABAB agonist (2)-baclofen (Waldmeier, 1991). The binding site by which gHB affects GABAB receptors is not clear, although a highly specific membrane gHB binding site, without affinity for GABA or GABAergic agonists, has been identified (Benavisea et al., 1982; Maitre et al., 1983). These data suggest that (S)-(2)-HA-966 may act by affecting GABAB-ergic neurotransmission. Shepard et al. (1995) proposed that both enantiomers of HA-966 may normalize DA firing pattern through a common mechanism related to GABAB. Both enantiomers are able to dose-dependently inhibit nigral DA neuronal firing, and in each case, this inhibition can be reversed by a GABAB antagonist, CGP-35348. However, (R)-(1)-HA-966 was found to be ;10-fold less potent than the negative enantiomer. In addition, both enantiomers, at different doses, display a normalization of firing pattern of midbrain DA neurons, resulting in an increase in the regularity of cell firing without changing the overall firing rate in chloral hydrate anesthetized rats (Shepard et al., 1995). Again, a 10-fold difference in potency was noted between the enantiomers. The normalization of firing pattern was not mimicked by the administration of a competitive NMDA receptor antagonist, NPC-12626, indicating that this effect is probably not due to blockade of the NMDA receptor complex (McMillen et al., 1992). Previously, we proposed that the normalization in firing pattern seen by Shepard et al. may be the mechanism by which (R)-(1)-HA966 prevents stress-induced changes in DA metabolism without disrupting basal DA turnover (Morrow et al., 1993). In addition, it seemed feasible that this hypothesis could be extended to explain the ability of (R)-(1)-HA-966 to prevent cocaine-induced locomotor sensitization (Morrow et al., 1995a, 1995b). If the normalization of DA neuron firing is necessary for these actions, the negative enantiomer of HA may provide efficacy in these models but at lower doses.


The development of vaccines against diseases requiring cell‐mediated immunity has been hampered by our lack of understanding of the memory T cells required to maintain immunity. Our lab has shown that a population of CD62Lhigh central memory T (TCM) cells mediates long‐term immunity to the intracellular protozoan Leishmania major. Our current studies are aimed at how TCM cells develop following infection. Using both polyclonal and transgenic donor T cells, we have identified two populations of Leishmania‐specific CD4+ T cells that emerge early following infection. One population has undergone greater than six rounds of division, expresses low levels of CD62L, and produces IFNγ in accordance with an effector phenotype (TEFF). We believe the second population to be themselves, or the precursors of, TCM cells based on their expression of high levels of CD62L and CCR7, which mediate lymph node (LN)‐homing, the IL‐7R, which promotes memory T cell survival, and the production of IL‐2. Sorting the two populations and restimulating them in vivo with antigen revealed only the CD62Lhigh cells could survive, consistent with their potential to become memory T cells. We have also found that while both cell types are primed in the first few days following infection, TEFF cells emerge from cells resident in the draining LN at the time of infection, and cells that are recruited into the LN at later times contribute to the TCM population.

In this paper we investigate the feasibility of using Passive Bistatic Radar, PBR, to provide security for a harbour area. There have been numerous publications on the suitability of passive radar for air surveillance applications. However, this paper focuses predominantly on maritime applications. We investigate the ability of passive radar to detect, track, and eventually manage, marine vessels (boats). The paper includes a case-study of the Livorno Harbour in Italy. Livorno has been chosen as it represents a busy maritime hub. Simulations are provided to determine the theoretical radar performance, which are then compared with experimental results from a DVB-T-based passive radar. It will be shown that passive radars represent a viable solution for harbour protection applications.


A single i.v. injection of 3 mg of the F(ab')2 fragment of MoAb 5‐1‐6 into rats induced immediate proteinuria (128.1 ± 80.7 mg/24 h on day 1) which lasted 1 –2 days. In contrast, rats administered 10 mg of the corresponding Fab fragment did not develop abnormal proteinuria even though an equivalent dose of the intact MoAb 5‐1‐6 far exceeded the nephritogenic dose. The total kidney binding of 125I‐Fab fragment was 209.5 ± 34.3 μg/2 kidneys. This exceeded that obtained by injection of 3 mg MoAb 5‐1‐6 IgG1 (58.9 ± 12.5 μg/2 kidneys at 1 h)and was similar to that obtained following injection of 3 mg F(ab')2 fragment (235.3 ± 16.9 μg/2 kidneys). Immunofluorescence (IF) showed a linear pattern along the glomerular capillary wall at I h after the administration of MoAb 5‐1‐6 IgG1. F(ab')2 or Fab fragment. On day 5, fine to coarse granules were observed scattered in F(ab')2 injected rat glomeruli. whereas granules were densely localized in Fab‐injected rat glomeruli. Complement‐depleted rats injected with 3 mg of MoAb 5‐1‐6 IgG 1 developed proteinuria with the same time course as non‐depleted rats. This observation, together with the ability of F(ab')2 to induce proteinuria. indicates that proteinuria induced by MoAb 5‐1‐6 is complement‐independent. This study suggests that MoAb 5‐1‐6‐induced proteinuria is initiated by cross‐linking of the epitopes by divalent MoAb 5‐1‐6 and is independent of complement activity.


In this study, I make audible a conversation in Alf Layla wa-Layla (The Thousand and One Nights) on the meaning and application of justice. Without assuming that Alf Layla constituted an organized whole, the study identifies, in the frame narrative and the first two chains of stories—all three understood to belong to the earliest bundle—a debate on the coincidence of successful interpretation and just rulership. By the end of these tales, i.e., by the twenty-seventh night, a complete tale is told. In these stories, I propose, Alf Layla adopts an attitude that privileges multiplicity over singular interpretation, in a fashion that affirms thecontingency of ethical questions.  The popularity of Alf Layla and the afterlives it enjoyed up to our present times—in the Arab world and the West—need not eclipse or substitute the Arabo-Islamic character the work came to exhibit, and the ethical questions it set out to address. In what has been read as fate, arbitrary logic, enchantment, magic, irrational thinking, and nocturnal dreamlike narratives, I suggest we can equally speak of a concern for justice. The study looks at Alf Layla's affinity with advice literature, but stresses the need to read it as a work of (semipopular) literature that pays witness to societal debates on justice.  Alf Layla, I suggest, belongs to Islamic culture in that the act of reading has been construed within hermeneutics that are largely informed by the ethical implication knowledge sharing entails. In how the stories find resolution to the crisis of the king, Alf Layla understands justice as an artificial and communal enterprise. The stories, more urgently, seem to suggest reading gears us towards a concern for the greater good.

Health behaviors begin early in life and whether or not a person knows about, understands, and practices HPBs can have long-term health implications, and can contribute to health disparities. Understanding how health behaviors change over time for adolescents is important (in this study younger girls reported less physical activity and were less likely to wear a seat belt when riding in a car). Understanding what African American girls know about keeping themselves healthy, and the health promoting behaviors they practice is important for intervention design to address inequities in health.

The core imaging x-ray spectrometer (CIXS) is one of several ITER diagnostic systems planned for measurements of the central ion and electron temperature profiles and of the toroidal and poloidal rotation velocity profiles, Ti, Te, vϕ, and vθ respectively. The diagnostic is based on precision determinations of the Doppler broadening and centroid shift of the lines of highly ionized heavy impurities using a curved Bragg crystal spectral disperser and imager. In a departure from earlier designs, the CIXS employs a novel imaging geometry utilizing spherically bent crystals operating at a Bragg angle near 45°, which spatially and spectrally resolves the x-ray emission from the plasma. In addition, the working radiation will be the L-shell emission of highly charged tungsten ions. Particular emphasis is placed on the strong 3d5/2 → 2p3/2 electric dipole transition in neon-like tungsten W64 +. Here we present the conceptual design of the instrument, which may include an x-ray calorimeter, and discuss the spectral features used in future measurements.

: Since 1967 neonatal intensive care units have incorporated Yale's "large room concept" of design. Many environmental problems of NICUs result, including the reducing of parents to occasional observers and overwhelming them with the sight of many sick babies, machinery and staff. The large room concept also plays a role in the risks of 24-hour intense fluorescent lighting, noise, electromagnetic hazards, ionizing radiation, and outgassing of surface materials. An alcove design is suggested, which would reduce these risks, and provide graded exposure of parents to the sick infants. As the infants recover, an alcove design would allow for parents to assume full care of their baby and even rooming-in.


This study investigated physique and Skeletal maturation of classified by somatotype of 202 male elementary school students attending Taekwondo Gym in Seoul. Radiographs of the left hand and wrist were taken with an 31 portable(70kVp; 20㎃) X-ray unit assembled in a portable apparatus designed and constructed according to the recommendations of Greulich and Pyle(1959). Skeletal age was determined by RUS scores(radius, ulna, and short bones) with TW2 method(Tanner et al., 1983). All skeletal maturity assessments of the samples were made by author. The reliability of the ratings by the study assessor was tested using a random sample of radiographs from 30 boys, aged 7-12 years. The absolute mean difference between first and second assessment was 0.17 years for the RUS(SD=0.27) system and 0.20 years for carpal(SD=0.26) system. Therefore, intra-observer reliability for skeletal age assessments were comparable with results of previous studies(Beunen et al. 1990; Song et al., 1998). All analysis were carried out by the SAS computer programs(SAS Institute, 1988). Skeletal maturity state was estimated by the calculation of 3, 10, 25, 50, 75, 90, and 97 percentiles. Comparisons between levels of maturity were applied by means of analysis of variance(ANOVA) and Duncan's a posteriori tests. The result showed that Physique increase nearly linearly between 7 and 12 years age boys. In factor of RUS score and bone age appeared Endomorphy average the highest in three groups in Somatotype.


In this article, the approximation of linear second-order distributed-parameter systems (DPS) is considered using a Galerkin approach. The resulting finite-dimensional approximation model also has a second-order structure and preserves the stability as well as the passivity. Furthermore, by extending the Krylov subspace methods for finite-dimensional systems of second order to DPS, the basis vectors of the Galerkin projection are determined such that the transfer behaviour of the DPS can be approximated by using moment matching. The structure-preserving approximation of an Euler–Bernoulli beam with Kelvin–Voigt damping demonstrates the results of the article.


The continuous growth of energy consumption has become a critical issue globally. According to the international energy agency, the energy consumed in residential and commercial buildings contributed about 40% of the total energy consumption in 2014. In recent years, building energy management has become a popular research topic. The techniques used in automatic control have evolved from static schedules specified manually into real-time sensing through wireless sensor network. The demand for a dedicated platform for building energy management systems has emerged later. Many proposed platforms focused on the high-level architecture and were based on existing standards and technologies. However, there was little research about the fundamental aspects of the infrastructure. In this paper, we propose a scheduling mechanism for the fundamental infrastructure based on the distributed pinwheel model. It addresses the issues of distributed real-time computing, and provides a more predictable system behavior for potential improvement of energy consumption of the infrastructure itself. Unlike the original distributed pinwheel model, we also take network delay into account, and present an adaptive method to mitigate the effects of variable network delay. The simulation results suggest that the total end-to-end delay can be reduced to 20% or lower for more than half of the input task sets without the presence of variable network delay. The adaptive method shows an improvement of 10.06% to 61.16% with the presence of variable network delay.


Casting process in small industries were using plain technology and recycled non-ferrous materials (such as aluminum, brass and copper). Casting was done by using sand mold casting and the casting systems were used kerosene furnace. The main constraint of such technology is that it is impossible to do diversification of products which have high sales value like souvenir products. These products are generally in form of sheets in various types of souvenirs which hardly be produced with existing casting technology. Material development will be determined the structure and properties of the optimum materials. The composition of aluminum alloy are 84.4% Al, 0.357% Ni, 2.74% Fe, 2.42% Cu, 0.179% Mn, 1.99% Zn, Sn 0.066%, 0.0704% Pb,  0061% Ti, and 0.066 Bi, where the influence of rising temperature causes the percentage of Mn, Zn, Mn, Mg Pb, Sn and Ti to decreased as a result of the evaporation process. Surface hardness decreased due to the increase in temperature, while the surface thickness has no effect.  The highest surface hardness found in 3 mm of cast thickness with temperature 650oC and 86.58 HBN. The endurance to impact loads is 3,36 Nm in 10 mm of thickness and temperature 750 o C.


✓ Experimental hydrocephalus was created in dogs by injection of kaolin into the cisterna magna. One month after the kaolin injection, ventriculojugular shunts were performed on certain of the hydrocephalic dogs. Shunted hydrocephalic dogs were killed 1 day or 1 week after placement of the shunt. Cerebrospinal fluid (CSF) pressures were measured prior to the kaolin administration and/or 1 month post-kaolin injection and/or after the shunting procedure. Choroid plexuses from control, hydrocephalic, and shunted hydrocephalic dogs were examined by light and electron microscopy. The hydrocephalic dogs had choroid plexuses with a flattened epithelium, compacted cytoplasm, and multiple large vacuoles usually containing small, rounded membrane-bound structures; it was postulated that these vacuolar structures were dilated multivesicular bodies possibly related to CSF resorption. Choroid plexuses from hydrocephalic dogs examined 1 day post-shunt closely resembled choroid plexuses from the control dogs. Intracytop...

ABSTRACT
REE (Rare Earth Element) or Rare Earth Elements are minerals that contain one or more elements which contained in a group of 17 chemical elements, this group consists of the chemical group lanthanide (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium) are added with scandium and yttrium. In the era of Industry 4.0 or modern industry REE (Rare Earth Element) is a very strategic commodity, the use of rare earth elements is needed in various fields ranging from the electronics industry, telecommunications, modern transportation industry and many more.
The REE (Rare Earth Element) density in Jambi-Sumatra occurred since the Early Mesozoic period, which was preceded by the formation of the Tantan Granite Formation to the Cenozoic period in the form of the Nagan Granite Formation.. The research location is in the Manau River, Merangin Regency which is part of the Sunda magmatic arc consists of intrusions granodiorite plutonic rock with xenolites in the form of andesites, micro diorites and diorites in the Tantan Formation, and in Nagan Formation consistsof intrusion of granite, granodiorite and Adamelit rocks. It's happen because the forming process of REE (Rare Earth Element) mineral deposits is strongly associated with the cooling of plutonic igneous rocks.
The purpose of this study are to determine the geological condition of the study area and its relationship to the REE (Rare Earth Element) and to find the potential of REE contained in the Tantan Formation and Nagan Formation in Merangin District, Jambi Province.

The main objective of this paper is to discuss about alarming increase in deaths and disability due to Atrial Fibrillation (AF), less efficiency in detection of AF, algorithms to detect AF and in the end a new algorithm is proposed to detect AF. This algorithm is also tested for its performance analysis using pre-recorded ECG signals. Atrial Fibrillation (AF) is a common Coronary Artery disease (CAD). In AF, the heart beats irregularly and rate of rhythm of heart becomes asynchronous as compared to rate of rhythm of heart of a healthy person. AF has higher rate of mortality and quality of life also worsens due to frequent hospitalization. With such high rate of mortality and less efficiency in detection of AF through Electrocardiogram (ECG) & even Holter, this cardiovascular disease is becoming threatening to lives of masses. Health Professionals and Scientists are working in synergy to find different ways to detect the AF cases in advance by developing the algorithms which can detect AF. An ECG signal is formed due to electrical activity of heart. Various Signal processing algorithms developed by research scientists can be applied upon open ECG databases, to detect the various parameters of ECG signals. These algorithms are tested on various open ECG and AF databases to find out their specificity and sensitivity. Algorithms for analysis of signals can be broadly classified in three different domains which are: (i) Time Domain Analysis, (ii) Frequency Domain Analysis and (iii) Non-Linear Analysis. In this paper, All of these techniques are briefly explained and a new technique is proposed for detection of AF. This technique involves statistical analysis of RR intervals and continuous slope analysis using four sample window of ECG signal to detect the presence of normal or abnormal P wave.


The title of this paper may seem surprising and, to some, clearly a case of heresy. However, a look at the statistical representation of the classic 'bathtub reliability' curve, suggests that, at some point, the numbers of 'findings' from an Infrared Thermographic (IR) program could diminish to zero for a period of time. Therefore, a facility may be left with an expensive piece of equipment, an extensive inspection program, trained thermographers, and few reportable results. This paper deals with some suggestions for preparing for this inevitable situation.


Mass spectra and translational and angular distributions of product ions formed in interactions of 13–33 eV ethanol molecular ions (C2H6O+•), as well as C2H7O+ and C2H5O+ ions, with a stainless steel surface were investigated to determine the partitioning of energy in the collisions with the surface. Distribution functions were derived from the data for the energy fractions going into internal excitation of the projectile, product translational energy and that absorbed by the surface. The peak values of the three energy fractions increased linearly with the incident projectile energy but their mutual ratios did not change. With increasing incident angle, the fraction of internal excitation did not change, the fraction of product translational energy increased, and the fraction absorbed by the surface correspondingly decreased. The ion survival probability increased substantially with increasing incident angle.

What is the role of immigrants on (American) Growth? To answer this perplex question, we undertake a massive effort of collecting, digitizing, and harmonizing micro and macro economic data from the 19th and early 20th century. The data originate from the historical manufacturing and demographic census of the United States, immigration records datasets and the universe of US patents. To analyze the counterfactual implications of alternative allocations of immigrants, we develop a dynamical trade model where heterogenous firms make innovation and exporting decisions across space and time. The model predicts that the timing and the spatial allocation of immigrant arrivals affect the path of growth outcomes for each location and the aggregate US economy. We use the structural equations arising from the model to interpret empirical findings from the difference-in-difference analysis for the importance of the influx of skilled immigrants on the differential growth of US counties. Counterfactual scenarios of alternative allocation of skilled immigrants from different countries across space and time reveal the economic impact of barriers to migration to the United States economy.


This paper represents initial research into ascertaining whether a biometric monitoring device can be used to identify that a trainee, who is undertaking an immersive training session, is being placed under sufficient stress for it to be classified as being realistic. The vehicle used for this initial research was a group of volunteer UK Police Traffic motor cyclists who were monitored during a series of eight hour shifts and their biometric results were analysed against their activities. For the purpose of this research, athletic training zones were used as an indication that an Officer's heart rate had increased to an abnormal level even though they were not undertaking physical activities. The results indicate that, in certain circumstances, Officers' heart rates rise into their training zone indicating that the current activity that is being undertaken may be causing them stress. This indicates that it is feasible to use a biometric monitoring device to measure stress thereby establishing the authenticity of immersive training. Author


A peer tutoring approach was taken for part of the teaching of mathematics to two different classes at a tertiary institution, most of whose students were preparing to be teachers at either the primary or secondary levels. It was hoped that peer tutoring would increase the learning and understanding of the students involved. As many of the students are training to become teachers, it was hoped that the work on peer tutoring might have particular relevance for them. From qualitative evidence, the experiment appears to have been successful. The vast majority of the students would like the experience to be repeated during their mathematics course.


Joyce was an exile for most of his life, a choice that put him in daily contact with languages other than English. For a writer who was so deeply interested in everyday experience and used it as mater ial for his creative work, it is not surprising that the multilingualism that surrounded him should be a recurrent feature in his writing. The aim of this essay is to discuss the presence of "the stranger" in lan guage by examining Joyce's attitude towards the foreigner, the per vasiveness of foreign-ness in his style, and the exploitation of alterity as a modality of communication. The interplay between English and foreign words in Joyce's texts results in an estrangement or "for eignizing" of the word, which opens a space for the presence of "the stranger" in Joyce's language. I will first consider Joyce as a writer who slips across the borders of the English language and address the significance of the presence of foreign words and phrases in Joyce's texts with specific reference to Italian ones. I will then comment on the reader's possible reactions to such foreignizing presences. Joyce's multilingual texts address both the monolingual English reader and the foreign reader with the result of displacing them both. But such a displacement, or dislocution (to use a term successfully introduced by Fritz Senn1), not only requires us to rethink our notions of writing and reading but also, paradoxi cally, challenges and even breaks down the usual discrimination between foreigners and fellow citizens. The second part of this essay will be concerned with issues of for eignization and translation. It will address the problem of Joyce's texts moving across the borders of different cultures, as happens when they are translated and rewritten in another language, and compare the foreignized reader with the foreign one. Can Joyce's for eignizing language be domesticated into another linguistic code, so that real foreign readers can have access to it in their own language? On one level, the answer is, of course, yes: Joyce's texts are translated into a number of western and eastern languages. They travel across

I have received many, many letters from readers of PEDIATRICS IN REVIEW. To publish most, or even some of them, would take precious space from the cognitive material in PIR. I have decided not to publish a Letters to the Editor section, but to handle the letters in the following ways. They fall into three quite distinct categories and I believe that each should be dealt with in a different way. The first group, and by far the majority so far, is very complimentary. While I would always like to publish laudatory comments in the Journal, I cannot justify the space for adulation. I will keep them for my ego file.


Aim: To explore the methods on analysis and evaluation of scorpion of Buthus martensii venom(SBMV) , and set up the quality standard of SBMV. Methods:Eight samples of SBMV were inspected by high performance liquid chromatography(HPLC). Results: SBMV could be separated into more than 40 components by HPLC. The fingerprint chromatograms of 8 SBMV samples were similar, but significantly different from lymph fluid of scorpion and snake venom. The precision and reduplication of chromatogram of a single SBMV sample was also proved. Conclusion:The fingerprint chromatogram of SBMV has been set up with HPLC,and those of the lymph fluid of scorpion and 3 kinds of snake venom have been detected with HPLC in order to prevent counterfeit.The experimental results are thought as an important evidence for making use of SBMV and it's components.


In summary, the potential and need for research in the area of supporting children with complex care needs in the community are vast. A mixture of methodologies is required: quantitative research designs to address effectiveness and efficiency, linking process variables with patient outcomes; qualitative methodologies to identify families' problems and needs, satisfaction with care, and to measure QoL; economic approaches to assess cost-benefit. Parents, siblings and the children themselves need to be involved in setting the research agenda. © 2004 Blackwell Publishing Ltd.


A pneumatic, horizontal force transducer has been developed and calibrated in the range 0-100 N. An approximate analysis shows that the calibration depends on two of its dimensions only. Tests were carried out to determine the effects of supply pressure and ambient temperature variations. It was found that a 25% change in supply pressure and a 28 degrees C change in ambient temperature caused the calibration to change by 4.0% and 2.2% respectively. The transducer is extremely stiff (a movement of 43 mu m was measured at full load), is easy to manufacture, requires no complex readout devices, and is capable of measuring forces over a wide range. The device operates at a supply pressure of 400 kPa with an air consumption of approximately 1.3*10-3 m3 s-1.


Unmanned aerial vehicle (UAV) recognition is of crucial importance due to the blowout amount of UAVs and their threats on the public safety. Although many UAV recognition methods based on deep learning (DL) have been proposed by utilizing the radio frequency fingerprints and have achieved appreciable results, their vulnerability to adversarial attacks, especially backdoor attacks, has not been studied. In this pa-per, in order to reveal the serious threat for DL-based UAV recognition encountered with backdoor attacks, a novel robust generative adversarial network (GAN)-enabled backdoor attack scheme is proposed. Moreover, the proposed GAN-based trigger generator not only emerges exceptional attack effectiveness, but also performs well in terms of attack stealthiness and migration ability. Simulation results obtained with the real collected UAV recognition dataset demonstrate that our proposed scheme outperforms the benchmark BadNets backdoor attack.


A demonstration is given that for two‐electron systems the Hartree—Fock and first natural spin orbitals are different functions. The method used is perturbation theory for which the zero‐order problem is the Hartree—Fock approximation. A perturbation expansion through the second order is obtained for the first natural spin orbital. The two orbitals begin to differ in the second order, and their energies in the fourth order. An equation for the second‐order part of the orbital difference function is derived. Estimates of the norms of the orbital difference functions are calculated for the ground states of the helium atom and the hydrogen molecule and are found to be small.


Basic research for developing a small hovering robot is performed. Small hovering robots will be very effective for inspecting and observing the site and circumstances in a narrow or dangerous space, where human cannot access safely. In this paper, how to hover the small robot successfully in air, especially by using rotating blades mechanisms is investigated, and it is clarified that measured lift force characteristics almost agree with the theory, and main parameters governing the lift force are the wing length and the rotation speed. Using a 135 mm diameter rotor, lift of 0.3-0.4 N can be obtained. The wing size should not be reduced so much because the wing length has drastic influence on the lift. For this reason, methods to reduce the robot size without reducing the wing length are investigated When putting a part of the rotor upon another one, the lift is weakened only less than 10%, and minimizing the robot size is possible. In order to verify the present technology level, a four-rotor hovering robot with a size of 238 mm square and a mass of 121 g is manufactured, and basic performance is exhibited

Also described is the project joining data for all observational types of binary and multiple stars, Binary star DataBase (BDB).


Attitudinal Choquet integral (ACI) extends Choquet integral (CI) through a consideration of a decision‐maker's (DM's) attitudinal character. In this paper, we generalize ACI, and the resulting operator is termed as generalized ACI (GACI). GACI adds to the efficacy of the ACI in the representation of a DM's unique and complex attitudinal character. It also generates a vast range of exponential ACI operators, such as harmonic ACI, ACI, quadratic ACI, to name a few. We further present induced GACI to consider additional information that may be associated with the arguments of aggregation. The special cases of the proposed operators are investigated. The usefulness of the proposed operators in modelling human decision behavior is shown through a case study.


This article presents a modeling and control of the Doubly Fed Induction Motor (DFIM), associated with two inverters controlled through the Pulse Width Modulation technique (PWM), the control of the DFIM is carried out by the approach of Rotor Flux Oriented Control (RFOC) according to the direct axis. In this approach, regulation is done by classic PI regulators, the latter having undesirable overruns and static errors in non-linear systems, for that the introduction of the control by sliding mode in place of the classic PI speed regulator, that is in the form of a control law based on this type of controller since it is invariant to the non-linearity of the system and precise, stable, simple and has a good response time, in order to validate the objectives of improving the DFIM behavior in front of the reference parameters, such as the speed and the torque imposed on the machine. The results of the proposed approach are validated by its implementation on the Matlab/Simulink environment.


HE coupled nonlinear equations of motion based on the von Karman theory of plates can be derived using Hamilton's principle.! A slightly modified form of these equations is the so called dynamic analog of the von Karman equations.M An alternative formulation of the von Karman equations consists of an equilibrium equation for the transverse motion and a compatibility equation for the inplane stresses. The aim of the present Note is to systematically consider higher-order Galerkin approximations to the solutions of the inplane equations of motion as well as the inplane compatibility equation for an assumed single mode expression for w. The computational technique outlined in Ref. 3 is adopted here. The present treatment confines to the assumed space mode approach. The modal equations based on these approximations as well as the approximate solution of the transverse equation of motion are discussed with the help of two typical plate geometries. The significant role of the stretching due to inplane displacements, which has sometimes been overlooked in the literature, is highlighted with the help of the present results. Some of the earlier investigations are considered in the light of the present investigation.


Objective To explore the effect of bilirubin level detection in cord blood on the risk prediction of pathological jaundice of newborns and early defecation intervention. Methods A total of 196 full-term newborns from June 2012 to June 2014 were divided into observation group( n = 92) and control group( n = 104). The observation group was treated with defecation intervention,while the control group was left untreated. The incidence rate of pathologic jaundice and the effect of defecation intervention on pathologic jaundice were observed. Results A total of 79 newborns had pathologic jaundice( 40. 31%). The bilirubin levels in cord blood of newborns with pathologic jaundice were higher than those of newborns without pathologic jaundice. The incidence rate of pathologic jaundice in observation group was lower than that in control group( P 0. 05). Conclusion The bilirubin level in cord blood may effectively predict the risk of incidence of hyperbilirubinemia,and defecation intervention may reduce the incidence rate of pathologic jaundice.

Abstract The benefits of using virtual environment display technology is the familiarity of the user with the modalities of that environment providing a very intuitive access to models or data sets represented by using this technology. Various different styles of input devices are typically used for such virtual environments, ranging from standard game-pads to high-end commercial devices like an A.R.T. flystick2. These devices work great for operations such as selection or navigating the scene. Whenever more sophisticated dialog-based input is required, these devices typically rely on traditional 2D metaphors projected into the virtual environment. The use of tablet devices can provide a significantly more natural input-paradigm under these circumstances. This paper describes the deployment of a standard Android tablet device that interfaces with a virtual environment over the wireless network. The tablet device was tested using traditional CAVE-type display configurations and wall-type display systems using various different 3D stereoscopic technology including active stereo and passive stereo.


Due to the limited supply in Peru of polyelectrolitic solutions recommended for the initial treatment of cholera diarrhea, a massive amount of isotonic sodium chloride solution was used during the recent cholera epidemic. This treatment proved adequate based on the low mortality rate, which compared favorably with international mortality rate reports. A preliminary observation of six adult Peruvian patients hospitalized with hypovolemic shock and metabolic acidosis secondary to cholera diarrhea showed remission of hypovolemic manifestations and significant improvement of serum bicarbonate, pCO 2 , and base excess after rapid intravenous infusion of a solution of isotonic sodium chloride. This intravenous solution seems adequate as the initial intravenous fluid for patients with severe cholera, as a logical alternative to currently recommended polyelectrolitic solutions containing bicarbonate or lactate.


We read the report "Hair-Grooming Syncope Seizures" by our colleagues Drs Lewis and Frank (Pediatrics. 1993;91:836-838), and waxed nostalgic regarding a cluster of similar cases which we aptly named "hair burning syncope." During an 18-month period in the late 1980s, several girls came to our outpatient clinic and emergency departments with generalized seizure activity following or in the midst of hair grooming using a hot curling (or uncurling) iron. After the first few cases, a clear pattern emerged: the patients were all black girls, aged 8 to 14 years; hair-grooming with a hot iron and various hair "gels" was always involved; the patient was seated or standing, with the groomer behind the patient; the parent was not directly supervising the activity; seizures were generalized, brief, and associated with brief postictal confusion.


Embryos/oocytes vitrification is an essential cryopreservation technique in IVF (in vitro fertilization) clinics. The reliable and effective transferring of embryos/oocytes is crucial to the subsequent steps in the whole procedure of vitrification. After each transferring, the straw needs to be replaced with a new one. Due to the uncertainties in the fabrication and installation, the exact knowledge of the kinematic model of the straw is usually unknown, and the relationship between the microscope and the straw is also unknown without calibration beforehand. In such situation, automatically transferring the oocytes from micropipette to the narrow tip of straw (0.7mm) is very challenging. In this paper, a new vision-guided robotic system is developed to automate the transferring of the oocyte without calibration. To this end, the unknown depth information is estimated then compensated by constructing a deep vision network through microscope image, and an approximate Jacobian control algorithm is also proposed to servo control the end tip of the uncalibrated straw to contact the micropipette with the vision feedback. After that, the oocyte is automatically transferred from the micropipette to the straw to finalize the task. The stability of the closed-loop control system is rigorously proved with Lyapunov methods, and the effectiveness of the developed robot is validated in experiments.


In much of the adoption practice literature, infertility "resolution" has been identified as an important, and in most cases necessary, precondition of adoption readiness. The findings of this research, based on interviews with 74 infertile couples, challenge this notion and suggest a reconceptualization of the relationship between infertility resolution and adoption readiness. Although some couples need to experience a sense of infertility closure before they can feel ready for adoption, others experience infertility and adoption in a concurrent manner as two ongoing, interpenetrating processes.


Abstract The effect of benzotriazole (C6H3N5) as a corrosion inhibitor for type 304 stainless steel in 2M H2SO4 has been studied using weight loss experiments, anodic and cathodic potentiostatic measurements, atomic emission spectrometry, and optical and scanning electron microscopy. Benzotriazole acted as a corrosion inhibitor over the entire range of potentials studied, from −625 to + 1250 m V with respect to a saturated calomel electrode, and did not promote selective alloy dissolution. The protective film was stable and adherent and obeyed the Langmuir isotherm, while values of the equilibrium adsorption constant suggested chemical adsorption. The maximum coverage obtained was 0·97 for stirred solutions and 1·0 for unstirred solutions, these values being associated with partial dissolution and lack of dissolution of inclusions respectively.


In the past, UV-blue-absorbing intraocular lenses (IOLs) were developed and then have been implanted to more than 200,000 patients. Recently, new UV absorbing IOLs, named `IOL-Photochrom' were invented. The latter have photochromic properties, mainly in the blue part of visible spectrum. Under low illumination their spectral transmission is similar to that of natural human lens of young individuals. On the other hand, in bright light of sunny days the transmission is the same as that of the natural lens of oldmen.

Au nanoparticles at the TiO$_2$ surface can enhance the photocatalytic H$_2$ generation performances owing to their electron transfer co-catalytic ability. Key to maximize the co-catalytic effect is a fine control over Au nanoparticle size and placement on the photocatalyst, in relation to parameters such as the TiO$_2$ morphology, illumination wavelength and pathway, and light penetration depth in the photocatalyst. Here we present an approach for site-selective intrinsic-decoration of anodic TiO$_2$ nanotubes (TNs) with Au nanoparticles: we produce, by Ti and Au co-sputtering, Ti-Au alloy layers that feature compositional gradients across their thickness; these layers, when anodized under self-ordering electrochemical conditions, can form Au-decorated TNs where the Au nanoparticle density and placement vary according to the Au concentration profile in the metal alloy substrates. Our results suggest that, the Au co-catalyst placement strongly affects the photocatalytic H$_2$ evolution performance of the TNs layers. We demonstrate that, when growing Au-decorated TNs, the use of Ti-Au substrates with a suitable Au compositional gradient can lead to higher H$_2$ evolution rates compared to TNs classically grown with a homogenous co-catalyst decoration. As a side effect, a proper placement of the co-catalyst nanoparticles allows for reducing the amount of noble metal without dumping the H$_2$ evolution activity.

The fabrication of catalytically stable nanocatalysts containing fine noble metal nanoparticles is an important research theme. We report a method for the synthesis of a hierarchically structured Pd@hm‐CeO2 multi‐yolk–shell nanocatalyst (h=hollow; m=mesoporous) containing sub‐10 nm Pd nanoparticles from pre‐made hydrophobic Pd nanoparticles. In the developed method, monodisperse hydrophobic Pd nanoparticles are first reacted with an iron oxide precursor iron(III) acetylacetonate to allow the deposition of iron oxide on their surface. In a Brij 56–water–cyclohexane reverse micelle system, the surface growth of iron oxide is found to mediate and, thus, facilitate the encapsulation of hydrophobic Pd nanoparticles in SiO2 to yield Pd‐Fe2O3@SiO2 nanoparticles in a high concentration. After removal of Fe2O3 by acid, the obtained Pd@SiO2 core–shell particles are reacted solvothermally with Ce(NO3)3 in an ethylene glycol–water–acetic acid mixture to produce multi‐core–shell Pd@SiO2@m‐CeO2 nanospheres. In each multi‐core–shell Pd@SiO2@m‐CeO2 nanosphere, several Pd@SiO2 particles are separately embedded in mesoporous CeO2. After selective removal of silica by NaOH, Pd@SiO2@m‐CeO2 nanospheres are transformed into the multi‐yolk–shell Pd@hm‐CeO2 nanocatalyst. Even with a low Pd loading at 0.4 wt %, the as‐prepared multi‐yolk–shell Pd@hm‐CeO2 nanocatalyst displays high catalytic activity in CO oxidation with 100 % CO conversion at 110 °C. In comparison, under the same catalytic conditions, the same amount of the same‐sized Pd nanoparticles supported on SiO2 achieves 100 % CO conversion at 180 °C. More importantly, the multi‐yolk–shell structure of the Pd@hm‐CeO2 nanocatalyst significantly enhances the stability of the catalyst. No loss in catalytic activity was observed on the Pd@hm‐CeO2 nanocatalyst treated at 550 °C for six hours. The Pd@hm‐CeO2 nanocatalyst also exhibited excellent catalytic performance and stability in the aerobic selective oxidation of cinnamyl alcohol to cinnamaldehyde.
