Abstract The turbulent-scale vertical velocity structure in a continental stratocumulus cloud is studied using a 3-mm wavelength Doppler radar operating in a vertically pointing mode. The radar observations provided 30-m sampling in the vertical with 2-s averages of 10 000 samples. Vertical velocity measurements were made continuously for an 8-h period and were further supported by measurements of cloud-base height from a laser ceilometer and liquid water path from a microwave radiometer. During the beginning of the observational period, the cloud layer extended between 200 and 800 m. The vertical velocity variance profiles evolved systematically over the period from a well-defined peak in the upper part of the cloud layer of ∼0.7 m2 s−2 to a peak in the lower part of the cloud layer of 0.2 m2 s−2 as the layer became decoupled later in the observing period. The vertical velocity skewness during the well-coupled conditions was negative through most of the cloud, consistent with the presence of relatively n...


Summary Hypoxic stress resulting from large numbers of germinating rice seedlings competing for the limited oxygen supply in initially air-saturated unagitated water in air-tight containers with and without exogenous nitrate supplementation inhibited normal seedling development. Subsequent aeration of the hypoxic aquatic environments with and without exogenous nitrate supplementation resulted in complete reversal of all non-normal seedlings into normal green plants. Reversal of hypoxic stress inhibition of normal rice seedling development during exposure to aeration confirms previous findings that exogenous nitrate supplementation was unable to serve as an alternative electron acceptor in place of molecular oxygen needed for normal seedling development. These observations are consistent with reports at a recent symposium on nitrate assimilation in that dissimilatory nitrate reduction has not been observed in higher plants.


Comprehensive airway management of the respiratory tract is crucial in the care of the burn patient especially in the presence of inhalation injury. Tracheostomy may be required either early or late in the post-burn period as an adjunct to the care of these patients. Its use has been controversial and there is no clear consensus on either the indications of or the correct timing of the procedure. However, tracheostomy still has a role in the management of acute burns to be performed in patients with specific indications, having clear cut benefits of improved patient comfort, role in management of patients with inhalational injury, and ease of maintenance of airway especially in patients likely to undergo repeated surgeries, the patients also requiring lesser doses of sedatives for maintenance.


In this article, the active vibration control of a smart structure made out of a single functionally graded piezoelectric material layer, equipped with a network of discrete electrodes, is studied. The material properties vary continuously across the direction of thickness, so that top and bottom surfaces consist of pure PZT4 and the mid surface is composed of pure aluminium. The percolation phenomenon is taken into account. A functionally graded piezoelectric material plate finite element based on the first-order shear deformation theory hypothesis and layer-wise approximation for electric potential is implemented. An optimization procedure is considered to define the relevant electrodes for actuators and sensors, based on controllable and observable criteria. An adaptative fuzzy controller system is used, activating with relevance the actuators according to the most excited eigenmodes. Simulations show the effectiveness of this kind of concept.


We study the effect of dimethyl sulfoxide, a solvent used in biological applications, on the lamellar phases of a zwitterionic surfactant. We used solutions with different proportions of dimethyl sulfoxide/water as solvents in order to analyze the effect on the lamellar phases (regular stacks of surfactant bilayers). The samples were analyzed by macroscopic visual observation, polarized light microscopy, linear rheology, and electron microscopy experiments. The results show that the variation of the dimethyl sulfoxide proportion in the solvent increases the curvature of the bilayers which leads to a transformation from a lamellar phase to an isotropic phase.


This paper reports the findings of a small-scale practitioner-research project which worked with reluctant writers in a primary school in the North of England to explore the role of oracy in the development of literacy. Carter (2000) and Duncan (2009) point out that literacy in the form of the written word has only existed for 3% of the time humans have used language. The other 97% comprises of oral storytelling and the spoken word. Clearly we have been storytellers for much longer that we have been writers

For example the storytelling of Homer in The Iliad and The Odyssey, which literary critics readily accept as great works of literature, is now widely considered by many historians and other scholars to have actually been composed through talking (or more accurately through singing) rather than through writing (Carter, 2000, Corbett,2010). Often such stories were improvisations (similar to contemporary jazz, jamming, rap or traditional music and folk-songs) where one performance is seldom the same as another. In today's literate society it is difficult to imagine how magnificent works of art, great stories and legends came to be composed in the absence of any form of reading or writing. On the contrary, it now seems that these shared worlds of meaning came into being through the interplay of a range and combination of storytelling 'technologies' and resources. These include orally shared mental pictures, familiar sounds and words, remembered rhymes or rhythmic phrases, individual and collective accounts of day to day human experience, and the heroic tales and legends which have carried human imagination and transmitted the hopes and fears of our ancestors across the ages.


Enhancement of the vibration signals measured from faulty bearings is the major step towards a successful fault detection and diagnosis. Bandpass filtering has shown to be an effective de-noising approach. Though simple, this method requires prior knowledge of the dominant resonance frequencies excited by the fault impacts. In this paper an on-line resonance frequency estimation algorithm is presented. This approach exploits the effect of variable shaft rotational speed on the measured vibration and applies a reliable wavelet based instantaneous frequency calculation method to find the proper center frequency for the bandpass filter. The proposed algorithm is evaluated using the vibrations measured from a faulty bearing and further validated with the results obtained based on the bearing impact analysis.


A central feature of Keynesian models is that prices do not rapidly adjust to clear all markets. If markets clear through price adjustment, as in the neoclassical model, the quantities of output, consumption, employment, and other variables that occur in the economy are just the market-clearing quantities. In the absence of rapid price adjustment, the actual quantities must be determined by some other process. In the simple Keynesian model described here, quantity (i.e., output) adjustment itself brings about equilibrium.


In recent years, more and more problems have taken place in state assets operation and supervision system, therefore, state assets supervision organizations are faced with unprecedented pressure. However, there are many problems in the legal system on authorized operation of state assets which play an important role in separating government administration with business management. So, it is urgent to establish legal system concerning state assets authorized operation. The author considers that the establishment of the legal system should be based on the principle that the authorized operation corporate of state assets is the represent of state assets buyer.


In this work, in the case of three primary fields, a reduction of the associativity equations (the Witten–Dijkgraaf–Verlinde–Verlinde system, see (Witten, 1990, Dijkgraaf et al., 1991, Dubrovin, 1994) with antidiagonal matrix ηij on the set of stationary points of a nondegenerate integral quadratic with respect to the first-order partial derivatives is constructed in an explicit form and its Liouville integrability is proved. In Mokhov's paper (Mokhov, 1995, Mokhov, 1998), these associativity equations were presented in the form of an integrable nondiagonalizable system of hydrodynamic type. In the papers (Ferapontov, Mokhov, 1996, Ferapontov et al., 1997, Mokhov, 1998), a bi-Hamiltonian representation for these equations and a nondegenerate integral quadratic with respect to the first-order partial derivatives were found. Using Mokhov's construction on canonical Hamiltonian property of an arbitrary evolutionary system on the set of stationary points of its nondegenerate integral of the papers (Mokhov, 1984, Mokhov, 1987), we construct explicitly the reduction for the integral quadratic with respect to the first-order partial derivatives, found explicitly the Hamiltonian of the corresponding canonical Hamiltonian system. We also found three functionally-independent integrals in involution with respect to the canonical Poisson bracket on the phase space for the constructed reduction of the associativity equations and thus proved the Liouville integrability of this reduction.

This study has been conducted through mixed-method approach to investigate the views of school principals and teachers regarding the power sources preferred by the principals. The study uses sequential explanatory design. First, quantitative data on teachers' perceptions of power sources is obtained from 320 secondary school teachers. After the analysis of quantitative data, qualitative data is obtained through interviews with six secondary school principals and six teachers in order to provide an in depth analysis of the quantitative data. The analyses of the teachers' views on power sources demonstrate that school principals use legitimate power, reward power, and expert power at most; they use charismatic power moderately and coercive power at least. The results are consistent with quantitative findings of the research. This study shows that diverse power sources, instead of relying on authority, make a positive impact on teachers' performance. Therefore, informing school principals about the power sources is vital for an effective administration.


F or decades, assessment of physical activity has captured the interest of epidemiologists, exercise scientists, and clinicians. Spurred by the rising cost of health care and the much publicized relationship between lack of physical activity and prevalence of chronic disease states (e.g., U.S. Department of Health and Human Services, 1996), the search for accurate and reliable field tests of physical activity has become a critical issue for clinicians and researchers interested in the prophylactic effects of physical activity. To date however, the quarry has proven elusive. Despite the volumes ofliterature and plethora of field methods for assessing physical activity, no single field measure of physical activity has proven valid, reliable, and logistically feasible over a wide range of populations, settings, and uses. In October 1999 the Cooper Institute in Dallas, Texas hosted in conjunction with the 9 Measurement and Evaluation Symposium of the American Association for Active Lifestyles and Fitness' Measurement and Evaluation Council the second conference in the Cooper Institute Conference Series. Titled Measurement of Physical Activity, the conference brought leaders in physical-activity assessment together with measurement specialists to


The article offers a systematic critique of identity politics and intersectionality that today dominate Western mainstream literary theory and Anglo-Saxon literary production by bringing to the fore a much overlooked critical intervention on the part of materialist (literary) system theorists and Western Marxist feminists. It then dissects the ways in which the trappings of identity politics and its upgraded version of intersectionality are manifested in Sandra Cisneros's The House on Mango Street, with the class in the triad of class, race and gender eventually weakened and removed from view.


This work suggests an adaptive tour route planning multimedia system designed to meet the needs of different tourists. Tour route planning is a 'traveling salesman problem' (TSP) type problem. TSP is an example of a combinatorial optimization problem and is known as NP-hard. As studied by many researchers exact, heuristic (approximation) and meta-heuristic algorithms are usually applied for NP problems. A promising meta-heuristic algorithm is proposed to solve the tour route planning problems which involves minimization of total traveling time, total travel expenses or the combined total traveling time and expenses. Moreover, a simple exchange local search heuristic is also applied to increase the exploitation (intensification) competence of the scheme. Restated, finding out the optimal planned tour using particle swarm optimization and increasing performance by exchange heuristic scheme is suggested. Simulation results indicate the PSO with exchange heuristic designed provides a promising strategy, and is efficient for solving tour route planning problems.


Abstract : The objective of this study was to obtain detailed information concerning the duty activities of Army Aircraft maintenance personnel. The data would serve as a basis for course modifications which would relate school training as closely as possible to actual job requirements. A comprehensive field survey of approximately 2,500 aircraft maintenance personnel was conducted. The principal objective of the survey was to determine in detail the requirements of the job in the field so that training courses might be tailored as closely as possible to those requirements. Some of the findings were as follows: (1) the typical man, both in organizational and field maintenance, estimated that he spent about two-thirds of his duty time engaged in aircraft maintenance or repair; (2) organizational and field maintenance personnel were not appreciably different on any of the background characteristics examined; and (3) the intention to reenlist in the Army was significantly more common among organizational than among field maintenance personnel.

In 1948, M. I. Graev [2] proved that the free topological group on a completely regular Hausdorff space is Hausdorff, by showing that the free group admits a certain locally invariant Hausdorff group topology. It is natural to ask if Graev's locally invariant topology is the free topological group topology. If X has the discrete topology, the answer is clearly in the affirmative. In 1973, Morris-Thompson [6] showed that if X is not totally disconnected then the answer is negative. Nickolas [7] showed that this is also the case if X has any (non-trivial) convergent sequence (for example, if X is any non-discrete metric space). Recently, Fay and Smith Thomas handled the case when X has a completely regular Hausdorff quotient space which has an infinite compact subspace (or more particularly a non-trivial convergent sequence).(Fay-Smith Thomas observe that their class of spaces includes some but not all those dealt with by Morris-Thompson.)


Asian dust and air pollution have been recently recognized as triggers in the incidence of acute myocardial infarction. The inflow of dust from the Sahara into Spain causes an increase in particulate matter (PM) levels in the atmosphere. The proximity to the Western Coast of Morocco and the Sahara Desert promotes the seasonality arrival of natural PM on the Canary Islands (Spain), leading to high concentrations of PM with an aerodynamic diameter over 10μm (PM10). The association of dust transport from the Sahara to the Atlantic Ocean and Mediterranean areas over the incidence of acute coronary syndromes (ACS), is unknown.

 The aim of the present study was to elucidate whether Saharan dust events in the dust belt - Canary Islands - is associated with the incidence of ACS.

 We retrospectively collected data of hospitalizations due to ACS in 2416 consecutive patients from a tertiary care hospital in Tenerife (Canary Islands–Spain), from December 2012 to December 2017. Taking advantage of Canary Islands location, we characterized the Saharan dust events using PMx measurements and dust modeling. Concentrations of PM10 and reactive gases are measured in the Air Quality Network of the Canary Islands by using the European reference method. We applied the time-stratified case crossover design to examine the association between Saharan dust events and the incidence of ACS. This design allows us to adjust for individual confounders, season, time trend and the day of week. Using conditional Poisson regression models, we estimated the impact of PM10 Saharan dust events on the incidence of ACS. Because the effects of Saharan dust events could persist over the course of a few days, we examined the lag effect from Day 0 to Day 5.

 The occurrence of Saharan dust events observed 0–5 days before the ACS was not significantly associated with the incidence of ACS. PM10 (μg/m3) effect was: lag 0 (IRR: 0.999, 95% CI: 0.977–1.022), lag 1 (IRR: 1.025, 95% CI: 0.988–1.063), lag 2 (IRR: 0.98, 95% CI: 0.928–1.042), lag 3 (IRR: 0.976, 95% CI: 0.944–1.011), lag 4 (IRR: 0.996, 95% CI: 0.983–1.008) and lag 5 (IRR: 0.996, 95% CI: 0.984–1.007). (Figure 1)
 Poisson regression model of PM10

 This negative study, the first to assess the impact of Saharan dust events as a potential trigger in the onset of ACS, shows that African dust is unlikely to be associated with the incidence of ACS.


We introduce new types of distance Fibonacci numbers which are closely related with number decompositions. Using special decompositions of the number we give a sequence of identities for them. Moreover, we give matrix generators for distance Fibonacci numbers and their direct formulas.

The objective of the Seoul ubiquitous (smart) city project was to find a method to measure a temperature, a humidity or a noise level in the urban areas. But the problem was that we would need to install a large number of sensors over a broad area and each sensor must be connected to the center-server through wired or wireless network. To solve this problem, we created the MSU (Moving Sensor Unit) which is a useful technical concept that helps with sensing a wide ubiquitous area. It turned out to be a great solution for the sensor problem. In this paper, we will present our MSU of the Grid Friend and introduce the processes of the Requirement Definition, Analysis & Design, Build and Implementation.


A field evaluation of insecticides for BW control on cotton was conducted at the Auburn University Plant Breeding Unit, Tallassee, Ala. Cotton was planted 4 May in 40-inch rows. Four treatments were replicated 4 times in a randomized complete block design. Plots were 9 rows by 100 ft with 25-ft alleys between blocks. Insecticides were applied with a high-clearance sprayer at the rate of 7.6 gal spray/acre (3.5 mph, 50 psi, 2 Teejet TX6 nozzles/row). Foliar applications of test materials were made 25 and 29 Jul and 3, 8, 18, 22, and 30 Aug. Bolstar was applied to all plots at 1 lb (AI)/acre on 3 Aug to control Heliothis spp. populations, and Monitor was applied to all plots at 0.5 lb (AI)/acre on 4 Aug to control aphids. BW feeding and oviposition damage were determined by examining 25 squares randomly selected from plants in the middle 3 rows in each plot at 2-5 DAT.

Hall measurements have been carried out for the Ge p-and n-MOSFETs with different substrate orientations and GeOx/Ge interface qualities. It is found that the significant reduction of effective mobility in high surface carrier concentration (Ns) or high normal field in Ge MOSFETs is attributed partly to the Ns loss due to large amounts of interface states inside the valence and conduction bands of Ge. The GeOx/Ge interface roughness is another reason limiting the high Ns mobility. It has been revealed that room temperature plasma post oxidation can realize Al2O3/GeOx/Ge gate stacks with atomically-flat GeOx/Ge interfaces. Ge MOSFETs with these interfaces have provided record high effective hole and electron mobility, which overcome the Si universal mobility in both low and high Ns regions.

Although research has identified that physical activity enhances the psychosocial, physiological, and the academic well-being of at-risk youth, little information is known about the unique challenges that adolescent Montagnard refugee youth face as they acculturate into the United States of America. Methods: This case study used photovoice methodology (Wang, 1998) to examine the physical activity participation related challenges that adolescent Montagnard immigrant youth encounter upon arrival into the United Stated of America.  Sixteen adolescent Montagnard youth (eight male and eight female) participated in this intensive study. They all completed a demographic survey with the use of two bilingual and bicultural interpreters (1 male and 1 female), participated in photovoice training on the use of cameras, took photographs, wrote photo captions, and shared stories about their pictures. A total 356 photographs were developed and analyzed.  Results: The results from the photovoice study clearly indicated that the environmental, socio-cultural, and socio-demographic were the main barriers to participating in physical activity as well as accessing community parks and recreation amenities. Conclusion: The findings reaffirmed that collaborations among all stakeholders were invaluable, especially in cross-cultural settings.

The objective of the current study was to investigate automatic milking systems (AMS) to find relationships between cow traffic system and efficiency of the AMS use. Milking records of cows from 11 Estonian dairy farms (46 AMS units) as well as data coming from four Latvian (7 AMS units) and two Polish (4 AMS units) dairy farms were analyzed to determine the system capacity. The highest capacity (milk yield per AMS unit per day) for Feed First cow traffic system (mean ± SD) 1,817 ± 276 kg was indicated in Estonian dairy farms. 142 and 255 kg more milk was obtained, respectively, compared with Milk First and Free cow traffic systems. Overall, average milk yield per cow per day was the highest with Milk First cow traffic system – 31.4 kg. It was 3.3 kg higher than with Feed First and 3.5 kg than Free cow traffic systems. The average machine-on time for milking was highest with Feed First traffic system, i.e. 85.3 ± 6.1%. However, the lower percentage of machine-on time for milking was observed for Free and Milk First cow traffic systems (76.4 ± 10.1% and 73.3 ± 7.2%, respectively).


The recently proposed quantum Arnold transformation is revisited and extended and its relation with other methods is emphasized. Possible applications are also outlined.


Hydrogenated amorphous carbon (a-C:H) films were deposited using direct-current plasma enhanced chemical vapor deposition (DC PECVD) process. The resulting film properties were studied with respect to the introduction of hydrogen (H2) and helium (He) in methane (CH4) plasma. The analysis techniques used to assess the film properties included optical transmission spectroscopy, Fourier transmission infrared (FTIR) spectroscopy and photoluminescence (PL) spectroscopy. Hydrogen dilution has significant effect on the deposition rate and optical band gap (Eg) of the film but helium dilution produces insignificant effects on these parameters. However, the hydrogen content in the film decreases steeply to a saturation value with increase in helium dilution. Increase in dilution of CH4 by both H and He gases result in decrease in PL efficiency.


Since ATM networks support many types of traffic generated by variety of applications, they must be able to guarantee QoS for these types of traffic. QoS control schemes should support the individual service classes that are available through the ATM networks. Since, in general, the quality of a VC is affected by other VCs in the same transmission path and in other service classes, traffic control should support multiple service classes. In this paper, we propose the mechanism for the buffer allocation and the cell scheduling algorithm with logical separation of a single buffer in the ATM switching system, and analyze the cell loss probability and the delay of each traffic (CBR/VBR/ABR) based on the weighted value and the dynamic cell service scheduling algorithm. The proposed switch system classifies composite traffics incoming to the switch, according to the characteristic of traffic, and then stores them in the logically separated buffers (quality service lines). And the proposed system adopts the round-robin service with weighted value in order to transmit cells in buffers through output port.


This study reports an investigation the effects of social media related to car information, materialism towards car ownership, and car use habit on student's ridesharing behavior based on the Theory of Planned Behavior framework of behavior model. Results indicated that Attitude, Subjective Norm, and Perceived Behavior Control explains up to 98.8% variance of behavioral intention to ride-share. In turn, intention and car use habit explain up to 26.9% of the variance of actual ridesharing behavior. If students' has a strong car use habit, the effect of social media and materialism on their attitude toward commuting by car to campus can be ignored. The implications of these findings are, even though both social media and materialism affect the student's attitude for using the car, however, students' car use habit gives more influence to the student's attitude for using the car than social media and materialism.


Estimation of the analog read noise level and quantizer threshold level to within a few hundredths of an electron can be obtained by measuring the output bit density, D, of a single-bit quanta image sensor (1bQIS) as a function of quanta exposure, H. Analysis of the D-H characteristics as a function of read noise and quantizer threshold levels is performed and a procedure for extraction of estimated read noise and quantizer threshold is suggested and demonstrated.


The article reveals the importance of using counterpropaganda elements in Ukrainian history lessons to counteract the hostile propaganda that constitutes the "hybrid" warfare waged against Ukraine by the Russian Federation. It is carried out through the media and education.It is noted that information aggression is carried out in order to erode national self-identification, weaken patriotism and readiness to defend the Fatherland. For a long time, Russia has been building an image of Ukraine as an enemy, including accusations of treason, the collapse of the USSR, abandonment of brotherly friendship, severance of economic and cultural relations; formation of myths about the threat posed by Ukraine to Russians; justification of artificiality of Ukraine as a state; discrediting the political leadership of Ukraine; rewriting history; making fun of the Ukrainian language, traditions, state symbols, etc.Information resistance to enemy propaganda is carried out by various state and public organizations, but a very large task is assigned to general educational institutions of the country and, first and foremost, to history lessons designed to produce media literacy in students, the ability to distinguish fakes and to counter them with the necessary facts and arguments.It is established that the methodology of teaching Ukrainian history has considerable potential for the organization of counter-propaganda work: methods, techniques, forms and ways of organizing educational work. First of all, it is the use of methods and techniques of problem-based learning, interactive technologies, media technologies, holding a lesson in the form of discussions, as well as the use of such types as a round table, expert group meetings, forum, symposium, debates, etc.The involvement of students in research activities: writing essays, mini-research, participation in projects is important for organizing counter-propaganda in the study of history.
Keywords: warfare; "hybrid" warfare; information warfare; propaganda; counterpropaganda; information counteraction; Ukrainian history lessons; methods techniques; forms and ways of counter-propaganda.


Iron coatings were prepared on steel and copper substrates using pulse electrodeposition technique. The influence of the average current density on the deposition rate and appearance, microhardness, and microstructure of the as-deposited Fe coating was investigated. As the results, the Fe coating had satisfactory appearance in the early stage of increasing of the average current density, but the appearance became poor with extended increasing of the current density. At the same time, the deposition rate of the iron coating increased with increasing current density and the best deposition efficiency was reached at a current density of 16 A/ dm 2. Moreover, the microhardness of the Fe coatings prepared at different deposition conditions was roughly characterized by Gaussian distribution, while the cubic crystal of the Fe coating had obvious preferred orientation.

This study evaluates the effectiveness of an enhancement program by examining a cohort of 57 students admitted on probationary status to an MSW program in 2002 and required to participate in the enhancement program. The demographics for students admitted on probation demonstrate that the program is effective in increasing the diversity of the student body and that students admitted on probation were very successful in the MSW program when compared to the cohort of 167 students admitted unconditionally.


Background Decades of research shows that early childhood interventions can positively impact children's short- and long-term health, academic and economic outcomes, but that interventions' effectiveness depend on their quality. Interest in continuous quality improvement (CQI) methods is rising among early childhood clinicians, educators and policymakers. We report on a study that integrated CQI into an existing professional development program that aimed to improve the quality of preschool education in Chile and the outcomes of participating children. Objectives To analyze how CQI methods can be applied in education to impact child development, in the context of a project centered on literacy instructional strategies supported by health, socio-emotional skills and family involvement. Methods Teachers from 40 low-income classrooms received training in instructional strategies. A subset of 18 early adopters participated in a Collaborative that taught CQI methods and facilitated shared learning. Children's language skills were assessed at the beginning and end of a 2 year period using an internationally validated test. Quasi-experimental methods (propensity scores and inverse-propensity weighting) were used to estimate the impact of professional development in instructional strategies combined with CQI methods versus professional development in instructional strategies alone. Results Children in classrooms whose teachers received professional development in language instruction plus CQI methods had larger increases in language skills (vocabulary, effect size 0.31, p<0.05) than children whose teachers received language instructional strategies alone. Conclusions CQI may be a valuable addition to promote change via professional development in low-income schools in Chile and warrant further examination for early childhood interventions in diverse contexts globally.


The composite cement materials composed of mono mineral and portland cement are introduced. On basis of a large number of strength tests,the proportion of monomineral has been given, at the same time, tests on mechanical properties were carried out. The reason why the composite cement materils cause tensile strength increase and the mechanism of its action have been analysed theoretically.


Although posterior tibial tendon (PTT) pathology has been attributed to numerous factors, most PTT dysfunction is caused by an intrinsic abnormality of the tendon.4,5 Extrinsic factors are rare. In the past, the diagnosis of PTT dysfunction was usually delayed, but an increased awareness of the condition has allowed earlier diagnosis and treatment. Os subtibiale is a relatively infrequent cause of PTT dysfunction, and it is important to differentiate it from an acute fracture.


Background: Metabolic syndrome (MetS) is a major risk factor for cardiac mortality and morbidity. Hyperhomocysteinemia and folic acid are related with MetS. Both MetS and hyperhomocysteinemia adversely affect heart rate variability (HRV).
Objectives: To assess the relationship of vitamin B12, folic acid and homocysteine levels with HRV in female MetS patients.
Methods: This cross sectional study was carried out on 40 female MetS patients of 25-45 years of age. Forty apparently healthy female with similar age were control. Chemiluminescent immunoassay measured serum vitamin B12, folic acid, homocysteine level and time domain parameters of HRV were recorded by Powerlab 8/35, AD instruments, Australia. Independent sample 't' test and pearson correlation coefficient test was used for statistical analysis
Results: In this study, all the time domain HRV variables ( Standard deviation of all RR intervals-SDRR, Coefficient variation of RR interval-CVRR, The square root of mean squared difference of RR intervals-RMSSD and Number of R-R interval differing >50ms from adjacent intervals divided by the total number of all R-R intervals-pRR50%) were significantly lower (p<0.05) in MetS patients compared to control. But correlation analysis showed only the folic acid level was significantly negatively correlated (p<0.05) with SDRR, CVRR, RMSSD and pRR50%.
Conclusion: The result of this study showed inverse relation of low HRV with low serum folic acid levels in female MetS patients.

BACKGROUND More inflammation is associated with greater risk incident hyperten- sion, and Black United States (US) adults have excess burden of hypertension. We investigated whether increased inflammation as quantified by higher C-reactive protein (CRP) explains the excess incidence in hypertension experienced by Black US adults. METHODS We included 6,548 Black and White REasons for Geographic and Racial Differences in Stroke (REGARDS) participants without hypertension at baseline (2003–2007) who attended a second visit (2013–2016). Sex-stratified risk ratios (RRs) for incident hypertension at the second exam in Black compared to White individuals were estimated using Poisson regression adjusted for groups of factors known to partially explain the Black–White differences in incident hypertension. We calculated the percent mediation by CRP of the racial difference in hypertension. RESULTS Baseline CRP was higher in Black participants. The Black–White RR for incident hypertension in the minimally adjusted model was 1.33 (95% confidence interval 1.22, 1.44) for males and 1.15 (1.04, 1.27) for females. CRP mediated 6.6% (95% confidence interval 2.7, 11.3%) of this association in females and 19.7% (9.8, 33.2%) in males. In females, CRP no longer mediated the Black–White RR in a model including waist circumference and body mass index, while in males the Black–White difference was fully attenuated in models including income, education and dietary patterns. females and diet and socioeco-nomic factors in males. Inflammation related to these risk factors might explain part of the Black–White disparity in hypertension.


The ISAR imaging technique is a well consolidated method for target image reconstruction. One of the main critical steps of the technique is motion compensation. This operation consists of removing from the received signal a phase term due to the translational motion of the target. As the target motion is not a priori known, motion parameters are typically estimated from the received data by means of autofocusing techniques. Different techniques are proposed in the literature. Their effectiveness is demonstrated by showing the results obtained by applying the algorithms to real and simulated data, without giving a quantitative analysis of their performance. The goal of this work is to analyze the performance of an image contrast-based ISAR autofocusing technique developed by the authors. The results are provided in terms of the statistics of the focusing parameter estimation errors.


The invention discloses a spatial stereo inline carrying system which comprises a ceiling with guide rails, a plurality of clamping boxes, a plurality of sets of treatment equipment and a spatial carrying device, wherein the plurality of clamping boxes are arranged on the bottom face of the ceiling and used for temporarily storing base plates; the plurality of sets of treatment equipment are positioned below the clamping boxes and used for treating the base plates; and the spatial carrying device is used for carrying the base plates between the clamping boxes and the treatment equipment, and is connected with the guide rails in a sliding manner. By adopting a stereo carrying mode, a manipulator, which is originally put on the ground, is put in the air, so that the area occupied by the carrying system is reduced; the treatment equipment for a base plate production line manufacture procedure is arranged centrally, so that the space utilization rate is increased greatly; moreover, the manipulator carries the base plates in the air, so that barriers among the plurality of sets of equipment are avoided, and the carrying efficiency is improved greatly; furthermore, the spatial carrying device is close to a fan filter unit (FFU), so that the base plates have relatively high cleanness; and the product yield can be improved.


Bowen's disease was initially described by JT Bowen in 1912 and is believed to be a squamous cell carcinoma in situ. It can develop on any part of the skin surfaces, particularly sun-exposed areas, but vulvar Bowen disease is quite rare. It is one of the vulvar premalignant lesions which can progress to squamous cell carcinoma if not diagnosed and treated early as most cases of vulvar premalignant lesions are treated by dermatologists with topical steroid therapy as was in our case. The incidence is very rare. This was the first case detected in our institution in the last 20 years. She underwent wide local excision of the lesion and currently disease-free at 12 months of follow-up.


A vibrant and effective TVET system has a central role in creating a well-trained workforce of both developed and developing countries. For Malaysia to position itself for the rapidly emerging Fourth Industrial Revolution (IR 4.0), it will need a well-trained technical workforce with skill sets that are needed in the new economy. TVET programmes are a key mechanism for bolstering Malaysia's human capital in order to become a more inclusive, innovation-driven economy. TVET has been recognised as a 'game changer' 2 in Malaysia's development since the 11th Malaysia Plan (2016-2020) and there have been efforts to improve governance, industry engagement and branding. The nation's TVET system has undergone remarkable transformation in recent years, but despite its successes, TVET is still saddled with numerous weaknesses and has not achieved the desired objective of producing sufficient skilled workers or being a preferred education pathway for most Malaysians.


A 50-minute-old male infant N.Y. had dyspnea had a large mass in the pharynx. This tumor was covered with skin and was attached to the upper pole of the right palatine tonsil. It had a helix, antihelix, scapha, lobulus and a pit which resembled an external acoustic meatus. Microscopic examination showed a squamous cell epithelium, stoma consisting of connective and fibrous tissue with glands, hair follicles and cartilage.The pathogenesis of this dermoid is unknown. It may represent the retention of a more primitive tissue of the auricle in the second internal cleft as early as three weeks in the embryonic stage. Both auricles were completely normal, so this dermoid may represent an included twin.


This paper describes a methodol- ogy of world modelling and path planning for a mobile robot. The world model, called a cer- tainty grid for obstacle representation,is ob- tained from readings of ultrasonic sensors and more accurate world model is built by using the information of neighboring sonar sensors. A linear programming method for the short- est paths from many origins to a destination is proposed. The global path is generated with off-line calculation but the local paths are ob- tained on-line by table look-up method. It is implemented on a physical mobile robot. The results show that the certainty grid which is updated by our proposed method well repre- sents a precise environment including the loca- tion of obstacles. The robot was enable to nav- igate to a destination avoiding obstacles with the path which is calculated by the proposed linear programming method.


By A survey on in-home childcare services in A City, a metropolitan suburb, revealed: 1) In two-thirds of the usage, parents are absent. Services are usually performed in the living/dining room. 2) The withholding of information is the most important privacy factor during in-home childcare services. This point is supported by the details of spatial manipulation before services. 3) The feeling of privacy being invaded is manifest in two-layer dwellings, and often latent-type and relaxed-type in one-layer dwellings. 4) The sense of privacy in the dwelling during services is also affected by the design of the space around the dwelling.


The aqueous extract of Dumortiera hirsuta (Swaegr.) Nees, a bryophyte, was found to be effective against seven postharvest phytopathogens tested. The fungitoxicity of the extract was measured by percent spore germination inhibition and percent radial growth inhibition using poisoned food technique. The inhibition of spore germination by the Dumortiera extract was within the range of 400 to 550 ppm. In poisoned food technique, out of seven postharvest phytopathogenic fungi tested six were completely inhibited by the Dumortiera extract with concentration range of 550 to 600 ppm. The mode of action of extract (350 ppm) was examined in the case of Aspergillus niger van Tieghem. Distinct morphological changes were observed in treated hyphae in comparison to control . The treatment clearly showed anomalies in the hyphae; cell wall of became flaccid, cytoplasm started leaving the cell wall and became granulated.


It is the key problem for the combined retaining structure to distribute the soil pressure to the pile-anchor and the soil nailing reasonably. For soil nailing, the soil of the retained section is strengthened by soil nails. If pile-anchor and soil nailing(PASN) are combined together, the prestress level will be reduced and the embedded depth of soldier pile be shortened, for the earth pressure acting on the pile-anchor retaining structure is observably lessened due to the strengthening action of soil nails to the soil. Generally, the side displacements of combined structure of PASN are very small and failure surface will not occur within the length of soil nails. So the section of soil nailing can be treated as a middle element during the earth pressure transferring to pile-anchor retaining structure, based on which we can admeasure the earth pressure in the combined structure of PASN and analyze the harmonious deformation between them.By comparing the calculation result of the side displacement and the observed result of the foundation pit side wall of an constructed project, the applicability of the soil pressure distribution model is verified,and this can provide some reference for the designing and calculating of the congener retaining structure.


In order to analyze the seismic behavior of tubular frame of concrete filled steel and popularize this type of structure in seismic areas,shaking table test and finite element analysis were carried out on an eightstory concrete filled steel tube(CFST) column frame model structure.The model responses of the largest earthquake force,story shear force,deformation and strain under different earthquake waves(El-Centro wave,Tianjin wave and Wuhan artificial wave) were measured.The experimental data agree well with those of ANSYS.The deformation of this structure presents a shear-flexural type,and the low mode has a great influence on the displacement of structure,while the high mode plays a leading role with the increasing acceleration of the peak value of earthquake wave.It is indicated that the CFST column frame has a good seismic behavior,and ANSYS8.1 can simulate the seismic responses of this structure well.

ABSTRACT We explore the physical reason why some forms of density functional theory (DFT) cannot model drying phenomena. It is found that DFT of using perturbed functional with respect to single bulk density cannot account for the drying transition, due to the inadequate description of local physical property for the growing vapour layer. Then we propose a new method to solve the problem for this type of DFT. The free energy functional is decomposed as the summation of a local contribution of equation-of-state effect and a non-local contribution from the nature of long-range interaction. Results show that the DFT developed by this strategy predict well for the drying transition, and thus provides a reliable tool to study similar phase behaviour. This transformative theoretical method in DFT provides a new way to construct free energy functional that could correctly model the thermodynamics and phase behaviour in drying or wetting system.


The full wave analysis of 2-D plasmon propagation in a high electron mobility transistor (HEMT) channel is presented. The Maxwell's equations and the hydrodynamic transport equations are solved simultaneously to model the structure, using the finite difference time domain (FDTD) numerical technique. By applying different bias voltages to the drain and the gate terminals, the properties of the 2-D plasmons along the channel are investigated. The analysis results show that the wavelength and the decay length of the propagation are significantly influenced by varying the bias voltages. So, it is possible to control the characteristics of the 2-D plasmon propagation along the channel and produce a reconfigurable structure for terahertz applications.


It is shown that 60° and 90° α and β dislocations give rise to piezoelectrically induced charge distributions and electric fields in the surrounding crystal. The general features of the charge distributions are discussed with special references to the relation between the nature of the distributions and the symmetry of the crystal. Finally, it is shown that the dislocation reaction (a0/2)[101]+(a0/2)[011]= (a0/2)[110] is self‐consistent as regards electrical properties.


Thirty nine fish species are recorded in eight lagoons on the southern coast of Quintana Roo. "Cichlasoma" urophthalmus, Gambusia yucatana, Poecilia orri and Eugerres plumieri were the most widely distributed species. Cluster analysis on the lagoons, based on presence-absence of the fishes, generated a dendrogram where two lagoon complexes are identifiable, divided by the access road to Mahahuak. The northern complex (Uvero, Placer, San Humberto and San Antonio) is characterized by the presence of Astyanax aunus, "C." synspilum and Thorichthys meeki. The southern complex (Rio Huach, Xcalak, Cementerio and La Aguada) is characterized by Cyprinodon artifrons, Floridichthys polyommus, Eucinostomus argenteus, E. jonessi and Gerres cinereus. Both beta and gamma diversity shown an increase from north to south, a fact explained mainly by the larger number of peripheral species migrating from the adjacent reef through permanent mangrove channels to Caribbean Sea in lagoons Rio Huach and Xcalak, in the southern complex, as well as the absence of primary species in these lagoons.


In many cases self-calibration is not able to yield a unique solution for the 3D reconstruction of a scene. This is due to the occurrence of critical motion sequences. If this is the case, an ambiguity is left on the reconstruction. In this paper we derive under which conditions correct novel views can be generated from ambiguous reconstructions. The problem is first approached from a theoretical point of view: It is proven that novel views are correct as long as the inclusion of the next view the sequence yields the same ambiguity on the reconstruction. The problem is therefore much related to the problem of critical motion sequences since the virtual camera can be arbitrarily moved within the smallest critical motion set that the recovered camera motion without distortions becoming visible. Based on these results a practical measure for the expected ambiguity on a novel view generated from the recovered structure and motion is derived. As an application a viewer was built that indicates if a specific novel view can be trusted or not by altering the background color.


The timing of carotid surgery after transient ischaemic attack (TIA) and stroke has been a matter of continuing uncertainty for vascular surgeons since the early 1970s, when case series by pioneers such as Jesse Thompson and James DeWeese reported high stroke risks ranging from 26 to 50 per cent in patients undergoing early surgery to remove tight carotid stenoses after acute stroke1,2. Thompson nevertheless recognized that outcomes might depend on the severity of the stroke and stated: 'Patients with mild pre-operative deficits, such as monoparesis or dysphasia, who were improving were those most likely to return to normal or near normal status. Only rarely did a patient with a profound frank stroke. . . make any dramatic improvement when subjected to operation in the acute phase, and many did not survive operation'. The theory was advanced that a fresh intracerebral infarct was susceptible to haemorrhage or extension after surgery in the early period after acute stroke and that it would be best to delay surgery for around 6 weeks to allow the infarct to mature. The counterargument to this policy has emerged recently, that the risk of recurrent stroke in the first few days after a TIA or minor stroke is much higher than previously estimated. The Oxford Vascular Study assessed the risk of stroke at 7, 30 and 90 days respectively after a TIA as 8, 11·5 and 17·3 per cent, and that after a minor stroke as 11·5, 15 and 18·5 per cent3. In other words, around half of potentially preventable strokes occur within the first week after TIA or stroke and the impact of carotid intervention would be greatly enhanced by a policy of urgent surgery. Recently, Ross Naylor, using pooled data from the European Carotid Surgery Trial (ECST), the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and the Veteran's Administration study, has calculated the impact of early surgery in terms of the number of strokes prevented per 1000 carotid operations4,5. Surgery within the first 2 weeks of a TIA or minor stroke prevented over 180 strokes, whereas operation at 2–4 weeks prevented just under 100 strokes and that at 4–12 weeks under 60 strokes; with a delay of more than 12 weeks just eight strokes per 1000 operations were avoided. Given the potential impact of urgent intervention, many authors have now questioned whether early surgery for minor stroke really does carry the high risks reported three decades ago, when many of the patients who underwent surgery had suffered major strokes with profound or unstable neurological deficits. A recent systematic review of 12 such reports revealed no significant difference in the risks of perioperative stroke or death between early or delayed surgery in patients with stable neurological symptoms after acute stroke6. Most of these reports were retrospective observational studies with a risk of patient selection bias for the timing of surgery. Furthermore, early surgery was defined variously in the different studies as within 1, 3, 4 or 6 weeks. Only one prospective randomized study specifically examined the timing of operation, in which early surgery was defined as within 30 days of minor stroke; the 2 per cent risk of perioperative stroke was the same for surgery both before and after this time interval7. The only other randomized study in this systematic review used pooled data from NASCET and ECST, although these trials were not specifically designed to look at timing of operation. The risk of any perioperative stroke and death after a TIA or minor stroke was essentially the same for surgery undertaken within 2 weeks or more than 2 weeks after the event (6·9 versus 7·0 per cent)5. Despite the limitations of this systematic review, it also demonstrated a higher risk of perioperative events in patients with unstable neurological symptoms such as crescendo TIA or stroke in evolution; the incidence of such events was over 18 per cent after early surgery compared with under 7 per cent when surgery was delayed, echoing the conclusions of Thompson 35 years previously. Patients with profound or unstable neurological deficits clearly have different operative risks from those whose deficits are minor and stable. In 2006, Tom Riles' department in New York published a retrospective review of its experiences with the timing of surgery in 1046 neurologically stable patients who had suffered TIA or stroke8. The perioperative stroke risk for both groups was significantly higher when surgery was performed within the first 4 weeks than when it was delayed for longer (TIA: 3·3 versus 0·9 per cent, P = 0·05; stroke:


The Portfolio Optimization task has long been studied in the Financial Services literature as a procedure to identify the basket of assets that satisfy desired conditions on the expected return and the associated risk. A well-known approach to tackle this task is the maximization of the Sharpe Ratio, achievable with a problem reformulation as Quadratic Programming. The problems in this class mapped to a QUBO can be solved via Quantum Annealing devices, which are expected to find high quality solutions. In this work we propose a QUBO formulation for the Sharpe Ratio maximization and compare the results both with the Quantum Computing state-of-the-art model and a classical benchmark. Under the assumptions that we require for the proposed formulation, we derive meaningful considerations about the solution quality found, measured as the value of Sharpe Ratio.


DEVELOPMENT OF RIBOZYMES AS THERAPEUTIC AGENTS FOR DOMINANT GENETIC DISEASE: Allele-Specific Cleavage of Collagen Transcripts Shows Competitive Binding Effects. 616


Background. Epithelial mesenchymal transition (EMT) plays an important regulatory role in obstructive nephropathy and renal fibrosis. As an intracellular energy sensor, AMP-activated protein kinase (AMPK) is essential in the process of EMT. The aim of this study was to reveal changes in the expression of AMPKα2 and to elucidate which AMPKα2 genes play a role during EMT. Methods. In this study, TGF-β1 was used to induce EMT in normal rat renal tubular epithelial (NRK-52E) cells. The shAMPKα2 lentivirus was used to interfere with AMPKα2 expression in EMT-derived NRK-52E cells, where AMPKα2 expression and EMT were detected. Differential gene expression after the AMPKα2 knockdown in EMT-derived NRK-52E cells was examined using a gene microarray. Possible regulatory pathways were analyzed using ingenuity pathway analysis (IPA) and differentially expressed genes were partially verified by quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting. Results. It was found that AMPKα2 was upregulated in TGF-β1-induced EMT-derived NRK-52E cells. EMT progression was significantly inhibited after the expression of AMPKα2 was downregulated by the shAMPKα2 lentivirus. A total of 1,588 differentially expressed genes were detected after the AMPKα2 knockdown in NRK-52E cells in which EMT occurred. The ERK/MAPK pathway was significantly impaired after the AMPKα2 knockdown, as indicated by the IPA analysis. Furthermore, qRT-PCR and western blot results revealed that the expression of AMPKα2, v-ets erythroblastosis virus E26 oncogene homolog-1 (ETS1), and ribosomal protein S6 kinase A1 (RPS6KA1) was upregulated after EMT in NRK-52E cells, while expression of ETS1 and RPS6KA1 was downregulated after the AMPKα2 knockdown. Conclusions. AMPKα2 plays an important role in the regulation of rat renal tubular EMT, which may be achieved by modulating ETS1 and RPS6KA1 in the ERK/MAPK pathway.

PROX1, a homeobox transcription factor, is essential for the development of the lymphatic vasculature. We have previously shown that PROX1 regulates the lymphatic endothelial (LEC) cell cycle. Post‐translational modifications such as phosphorylation, ubiquitination and SUMOylation are able to modulate protein‐protein interactions, protein stability, protein function, and cell cycle progression. We treated endogenous PROX1 with lambda phosphatase and measured its phosphorylation status by western blotting. We also deleted the Prospero domain 1, which contains the majority of the predicted phosphorylation sites, and used immunocytochemistry, western blotting and luciferase to determine its localization, expression level and function. We observed that PROX1 is phosphorylated in both HepG2 (hepatocellular carcinoma cells) and human LECs. The degree of PROX1 phosphorylation was dependent on the cell cycle phase. Deletion of the PD1 domain resulted in localization of PROX1 to the cytoplasm which could be rescued by the nuclear export inhibitor leptomycin B. We have demonstrated for the first time that PROX1 is phosphorylated and propose a potential role for the PD1 domain in regulating PROX1's subcellular localization. This will lead to a new understanding of how PROX1 regulates lymphatic endothelial cell growth. This work is funded by the Manitoba Health Research Council.


The present study was carried out on forty local and foreign broiler  chickens (twenty for each) (one day old), reared for 35 days under cold environment (January and February-2015). The aim of this study was to assess the histopathological effect of cold stress and the cellular response of pulmonary tissue. All experimental animals were weighed then  sacrificed and the lungs were collected and weighed. Specimens were fixed by 10% neutral buffer formalin. Routine histological preparations were carried out. Hematoxylin & Eosin was used for staining. At the end of the experiment, both breeds showed different signs of respiratory response. The work revealed that the pulmonary cellular lesions in foreign breed were more severe andmore extensive than inlocal breed. In local breed, the cellular regenerative response represented by infiltration of immune cells was more efficient , and consequently, the current study revealed that Iraqi local breed was more resistant to environmental stress than European foreign breed which registered a respiratory infection at the end of rearing period. The larger relative size of the lung in European breed may explain the higher injury of its pulmonary tissue. It was concluded that the local breed was more adaptive to cold stress than the foreign breed.


Simple Summary Classical swine fever is a highly contagious disease that infects both domestic pigs and wild boars. Classical swine fever virus (CSFV) has not been detected in domestic pigs in South Korea since 2016, but has been increasing in wild boars since 2017. Two cases of CSFV subgenotype 2.1d were detected in wild Korean boars in 2011, but then no cases were detected until 2016; however, 16 cases of CSFV were detected between 2017 and 2019. In this study, we report seven CSFV-positive samples obtained from wild boars in 2020. In addition, although 13 mtDNA haplotypes were detected in wild boars in South Korea, all 25 cases of CSFV that occurred in wild boars between 2011 and 2020 were detected in animals with haplotype 01. Abstract Classical swine fever virus (CSFV) is one of the major pathogens that causes severe economic damage to the swine industry. Circulation of CSFV in wild boars carries the potential risk of reintroducing the virus into CSFV-free pig farms. This study carried out a genetic analysis of CSFV isolates from wild boars and analyzed the mtDNA haplotypes of the wild boars. Blood samples (n = 2140) from wild Korean boars captured in 2020 were subjected to qRT-PCR to detect CSFV, which was classified as subgenotype 2.1d based on phylogenetic analysis. CSFV had been detected in wild boars only in northern regions (Gangwon and Gyeonggi) of South Korea between 2011 and 2019. However, CSFV was identified in wild boars in the more southern regions (Chungbuk and Gyeongbuk) in 2020. Based on mitochondrial DNA analysis, all wild boars with CSFV were haplotype 01 (H01). Thus, we presume that the H01 haplotype is more susceptible to CSFV. In the future, infection of wild boars by CSFV is expected to occur intermittently every year, and we predict that most wild boars infected with CSFV will be haplotype H01.


Composite topological structures such as superheavy"quasi-stable strings"(QSS) and"walls bounded by strings"(WBS) arise in realistic extensions of the Standard Model of high energy physics. We show that the gravitational radiation emitted in the early universe by these two unstable structures with a dimensionless string tension $G\mu\approx 10^{-6}$ is consistent with the NANOGrav evidence of low frequency gravitational background as well as the recent LIGO-VIRGO constraints, provided the superheavy strings and monopoles experience a certain amount of inflation. For the case of walls bounded by strings, the domain walls arise from the spontaneous breaking of a remnant discrete gauge symmetry around the electroweak scale. The quasi-stable strings, on the other hand, arise from a two step breaking of a local gauge symmetry. The monopoles appear from the first breaking and get connected to strings that arise from the second breaking. Both composite structures decay by emitting gravitational waves over a wide frequency range. The Bayes factors for QSS and WBS relative to the inspiraling supermassive black hole binaries are estimated to be about 60 and 30 respectively, which are comparable with that of metastable strings and cosmic superstrings.


Helium was considered for use as a propellant in a plasma propulsion system because of its low molecular weight. To obtain reasonable exhauat velocities (greater than 10,000 m/sec) it is necessary to heat the gas to temperatures at which an appreciable ionization occurs. In order to assess the potentially available exhaust velocities when ionization is present, it is necessary to have a Mollier chart to determine isentropic expansions. The thermodynannic properties of helium were computed over a temperature range of 6000 to 60,000 deg K and a pressure range of 10/sup -4/ to 10/sup -2/ atm. A Mollier chart was constructed from this data. (auth)


Numerous recent studies have implicated brain opioid systems in the regulation of feeding and taste-motivated behavior. In addition, we have shown that blockade of opioid receptors by naloxone inhibits intake of highly preferred solutions of saccharin' and that repeated daily naloxone in naive animals blocks normal preference acquisition.' Opioid receptors are found in high concentrations in numerous brain areas, particularly in sensory and limbic systems. Furthermore, chronic blockade of these receptors leads to receptor up-regulation in many of these areas (including taste and feeding areas) and to an increased sensitivity to morphine analgesia. Given the role of opioid systems in taste and feeding, the following study aimed to determine whether chronic naloxone might also modify taste preferences. Ten adult male Sprague-Dawley albino rats were implanted with subcutaneous Alzet minipumps (Model 2002) containing either 150 mg/ml Naloxone-HC1 (n = 6) or 0.9% NaCl (n = 4). An automated lick-monitoring system was used to measure consumption twice daily during two weeks of treatment and for one week following pump removal. At 9 A.M. daily (4 h after lights on) each animal was offered three calibrated bottles containing either sucrose (0.2 M and 0.7 M> or water. For this test animals were nondeprived. At 10 A.M. a six-hour period of water deprivation began and at 4 P.M. each animal was again offered three bottles, this time containing either quinine-HC1 (0.ooOOl M or O.ooOO3 M ) or water. Intake data were collected for the following six hours and these three bottles remained on the cages until 9 A.M. the following day. Additional tests for morphine analgesia were carried out during the week following pump removal. In a previous experiment we have shown that chronic naloxone (NAL) treatment identical to that used in this study leads to the widespread up-regulation of brain opioid receptors that is both regionally and receptor subtype specific. In this study we found that this treatment also modifies intake of sucrose and quinine solutions. Contrary to expectations based on our previous work using repeated daily injections of NAL, we did not see an inhibition of sucrose intake during the period of exposure but instead intake tended to gradually increase over the two weeks of testing. This effect persisted after pump removal and was due both to a greater increase in drinking during the first few minutes of the session and to a delay in satiation in the naloxonetreated animals. Quinine drinking during the two weeks of drug exposure was not


The expression "big data" is ubiquitous in the business world today, but few undergraduate business students have the opportunity to gain practical experience with how new business analytics tools can be used in decision making. This article describes a set of hands-on labs that prepare students to incorporate streaming data analysis into group research projects. Splunk is used to help students analyze and visualize streaming social media data. An evaluation of student projects and student survey results show that this practical approach of training students to manipulate and visualize big data was largely successful in achieving instructional goals.


I put in a book once, by hook or by crook The whole race (as I thought) of a 'feller,' Who happily pleas'd the town's taste (much diseas'd), And the name of this person was Weller.1 More than the town's taste was pleased. Dickens and his publishers were jubilant as they watched sales soar from a pre-Weller 500 to 40,000 copies of each monthly number after Sam Weller's appearance in Chapter X. Both Mr. Pickwick and Sam became the objects of a national mania, and the above figures strongly indicate that Sam was carrying Mr. Pickwick on his coat-tails. Pickwick was published in 1836; a year later a dramatization, Sam Weller; or, The Pickwickians, opened in New York and Philadelphia and ran well in spite of poor reviews.2 This is popular success, and Sam is indeed a man of the people, 'as ordinary and perfect a reality as anything in the London street.'3 It is not surprising that the adulation of Weller was accompanied by emulation of the form of proverbial expression that characterized his speech. The form is readily recognizable: ' ,' as said, when (as, and) (s)he . I.e., a quotation, speaker named or otherwise identified, and a clause or phrase which puts the quotation in a new light or an incongruous setting, the total effect being ironic. In the United States alone more than one hundred of what came to be called wellerisms (a term first used in 1845), and were jingoistically referred to as Yankeeisms, appeared in popular books during the five decades following Weller's appearance.4 More than five hundred have been collected from periodical publications of the same period.5 By 1867 the form had attracted scholarly attention, and M. Maass published '39 Odd Similes aus den Pickwick Papers von Charles Dickens.'6 Maass included in his list two simple folk similes-'right as a trivet' and 'looks as convivial as a live trout in a lime-basket'-but he did place each of the items in its immediate context in the story. The notion of context was lost on his successors until very recently. For comparative purposes Maass also demonstrated the prevalence of the form in Germany with examples from proverb collections. Since this pioneering venture, folklorists, philologists, and paremiologists have combed earlier collections and come up with wellerisms from classical Greek, through sixteenth-century German and Italian, down to persistence or revival of the form in the twentieth century.' There are even wellerisms in Africa, almost the only examples collected in context from oral sources.8 Because of this penchant of collectors to collect from collections, one cannot point to versions in nineteenth-century oral tradition of precisely the wellerisms used by Sam and his father, Tony Weller. Clearly the proverbial form was not original with Dickens. Henry Mayhew, although not a folklorist, did field work in London among the urban folk during the first half of the nineteenth century and published interviews with the London poor as closely as possible in their own vernacular.

Knowledge from Software Engineering research often does not make it to practice. A reason for this is the Not Applicable Here (NAH) syndrome -- practitioners often feel that the methods being proposed, and maybe even evaluated in controlled studies, are not applicable to their situation. Another reason is that often there is lack of wide spread experimentation and empirical validation, casting doubts on the applicability of the new knowledge. This talk will argue that we need to engage with practitioners in a more meaningful manner by having them do research and answer some questions that are relevant to them, rather than just provide data to researchers with minimal use of that data for themselves. This understanding achieved through research by practitioners may sometimes be applicable in a limited context, but can help software engineering researchers build more general models and approaches. If we can get the practitioners to participate in research while continuing their practice, we have "crowd researching" which can potentially provide benefits similar to crowd sourcing for information. We will discuss some examples of the types of questions that practitioners can do research on, while continuing their practice.


In the recent past, Web services have entered the competition for distributed e-commerce platforms. By exploiting existing open standards such as XML and HTTP, Web services promise unprecedented levels of interoperation between programs on different frameworks. Questions remain on how to capitalize on this new technology.
This dissertation attempts to answer the questions from a service location perspective. We focus on the behaviors of Web services intermediaries that serve as common interfaces to their clients and obtain Web services from independent Web services providers on behalf of their clients. The distributed nature of Web services and the ever-increasing prominence of network latency in determining server performance justify the study of locating servers of Web services intermediaries on the Internet to optimize their performance and/or financial goals. We propose a mathematical integer programming model to help these intermediaries decide on the locations and usage rates of their servers.
As expected, the proposed model becomes computationally intractable as the number of participants increases. We therefore develop an efficient heuristic method named DAL to tackle the problem. For the problems tested, the DAL heuristics provide near optimal solutions in short computer times and with limited computer memory usage.


As rate in an elderly population and expanding their range of activity rapidly increase, the demographics of the elderly population on a use of transportation also rise. Elderly pedestrians often find it difficult to react promptly to the traffic accidents as they are less perceptive of the dangers ...


The article presents the issues of the Life Cycle Assessment (LCA) use in contemporary ecological education, in relation to the problem of sustainable development. Based on the analysis of the literature, legal norms and strategic documents, the theoretical aspects of LCA as a tool used in numerous areas and environmental management processes were discussed and the significance of its use in the process of shaping ecological awareness of both the whole society and enterprises was demonstrated. The role of using computer programs based on LCA technology (such as SimaPro) in the teaching process at the higher education level was also emphasised.

Keywords: Environmental awareness, ecological education, sustainable development, LCA, life cycle assessment.


The goal of this paper is to share information regarding advanced modelling techniques used to solve complex hydraulic flow issues using the HEC-2 Computer Model (1990). There are several hydraulically significant aspects of this otherwise routine HEC-2 study. The problems encountered included: split flow, both returning and non-returning to the main channel stem as well as changing flow regimes in the channel. The channel's flow regime changed from supercritical at the start of the study to subcritical flow within the first several cross sections; however, the flow regime remained subcritical for the remainder of the reach length.


In many countries encephalitis had become a prominent cause of public health. Encephalitis is a viral disease which is transmitted through mosquitoes. Because of the unavailability of the preventive vaccines this disease is becoming endemic in many countries. The computational mechanisms have improved the identification of vaccine by reverse vaccinology. The present study deals with the development of Encephalitis virus inhibitors by the toxin extracted from the plants belonging to family Rhododendrons which is followed by molecular docking against Encephalitis viruses. Molecular docking studies were performed using iGEMDOCK module and the HEX software. The grayanotoxin was docked with the encephalitis virus which shows the antiviral properties against these viruses, which could be used for further analysis to inhibit Encephalitis virus replication. According to iGemdock software Japanese encephalitis virus shows highest binding affinity with grayanotoxin (-316.219 kcal/mol) and according to Hex, Murray valley encephalitis has highest binding affinity with grayanotoxin (-225.2 kcal/mol). This change in the binding affinity is due to the reason that both software works on different algorithms. Hence docking results predicted that grayanotoxin have better drug activity with Japanese encephalitis virus and Murray valley encephalitis virus. Thus this study highlights the role of immense therapeutic capacity stored in plants products against major life threatening diseases.


By regarding textile patterns as bi-dimensional images that are transformed in a tridimensional printed fabric, this article looks into the author's personal interpretation of the diverse sensible interactions between the poetic image and the construction of semantic and visual narratives in pattern design. Following the concepts of Narrative and Structure, it is regarded that this creative process evolves from a poetic sketch towards the linguistic manipulation of the motif through to its organization as plots and blocks. At last the motif organized in a structure of repetition (rapport) becomes a pattern, generating the textile pattern printed in fabric that, eventually, is transformed in a textile object, thus affording the generation of pleasing living spaces that playa role in stimulating our poetic imagination.


Body weight and body height measurements have been carried out on two samples of n = 1236 pupils between 8 and 16 years of age from schools in Bremen and of n = 1401 pupils of the same age group from the rural surroundings of Bremen. From this information the values of the Rohrer-index and body surface have been calculated for each individual. The differences in these four anthropometric parameters between the rural and urban children were analysed by sex and age.


A novel adaptive iterative learning control approach is proposed for a class of hybrid parametric nonlinear time-delay systems. The approach consisted of a differential-deference type updating law and a learning control law, can deal with the non-uniform trajectory tracking problem, in which avoids the restricted on the tracking trajectory in the traditional ILC. A sufficient condition of tracking error converging to zero in the means of mean-square on the finite interval is also given by constructing a novel composite energy function. A simulation example shows the feasibility and efficiency of the approach.


The effects of thermal treatment at temperatures in the 177–250°C. range for 2 hr. on solution-grown single crystals of poly-4-methylpentene-1 have been studied by using electron microscopy. Crystals were grown both from 0.02% pentyl acetate solution at 110°C. and from 0.02% toluene solutions at temperatures less than 80°C. A number of distinct types of crystals have been obtained in the same or in separate solutions depending on the crystallization conditions. These crystals have some morphological characteristics in common such as a square outline with well-defined faces. The contrasting features include such things as a marked difference in relative size, with the smaller crystals showing extensive overgrowth and collapse markings. Observations by means of differential scanning calorimetry (DSC) on the melting behavior of these various crystals show the presence of distinct and characteristic melting points. The effects of a given thermal treatment depend on the type of crystals used, with the larger crystals showing greater stability. The first effects are the appearance of lines, notches at the edges, and holes. An increase in temperature results in an increase in these effects with the formation of fibrillar structures. Consideration is given to the influence of molecular conformation and molecular chain folding on the observed results.


Presents two algorithms for estimating near-shore bathymetry from synthetic aperture radar (SAR) data. The first algorithm utilizes the kinematics of the shoaling waves to extract depths under the assumption of no significant current in the direction of wave propagation. The second algorithm utilizes the average radar cross section to estimate the rate of wave energy dissipation due to breaking, and then relates this dissipation to water depth. The two algorithms are complimentary in where they can estimate water depths; the kinematics algorithms works outside of the surf zone while the energy dissipation algorithm works within the surf zone so together they can span the near-shore region. The authors first present the airborne SAR data set that was used to test the algorithms, then they discuss each algorithm, including results from the SAR data set.


Fuzzy extreme analysis (FEA) is expedient for those cases when it is necessary to analyze the most important details of a shape of a signal or its spectrum as well as to find out its envelope. It is based on a capture of only main signal extremes and intervals between them on the basis of comparing of the signal increases with assigned limits. Apart from it, FEA allows to significantly compress of signals as well. This paper presents the general FEA algorithm and ways of a signal reconstruction after FEA and defining its envelope. Simulation results are presented to prove the proposed method and to compare it with classic approach.


The reported investigation is part of a program that was established for deriving radiological source terms at a nuclear facility's atmospheric boundaries under postulated accident conditions. The overall program consists of three parts: (1) accident delineation and survey, (2) internal source term characterization and release, and (3) induced flow and material transport. This report is an outline of pertinent induced-flow and material transport literature. Our objectives are to develop analytical techniques and data that will permit prediction of accident-induced transport of airborne material to a plant's atmospheric boundaries. Prediction of material transport requires investigation of the areas of flow dynamics and reentrainment/deposition. A review of material transport, fluid dynamics, and reentrainment/deposition literature is discussed. In particular, those references dealing with model development are discussed with special emphasis on application to a facility's interconnected ventilation system. 176 references.


Hall conductivity in the presence of a dephasing environment has recently been investigated with a dissipative term introduced phenomenologically. In this paper, we study the dissipative topological insulator (TI) and its topological transition in the presence of quantized electromagnetic environments. A Lindblad-type equation is derived to determine the dynamics of a two-band system. When the two-band model describes TIs, the environment may be the fluctuations of radiation that surround the TIs. We find the dependence of decay rates in the master equation on Bloch vectors in the two-band system, which leads to a mixing of the band occupations. Hence the environment-induced current is in general not perfectly topological in the presence of coupling to the environment, although deviations are small in the weak limit. As an illustration, we apply the Bloch-vector-dependent master equation to TIs and calculate the Hall conductance of tight-binding electrons in a two-dimensional lattice. The influence of environments on the Hall conductance is presented and discussed. The calculations show that the phase transition points of the TIs are robust against the quantized electromagnetic environment. The results might bridge the gap between quantum optics and topological photonic materials.

The aim of the present study was a detailed assessment of background phase errors in 4D Flow MRI and limitations of image‐based correction.


At present, there are relatively few studies on the slug flow generation mode obtained by exchanging gas-liquid two-phase inlets. In this study, an experimental system combining microfluidic devices and high-speed cameras was used to study the effects of gas-liquid two-phase flow rate, liquid physical parameters, etc., On the characteristic length, generation period and other generation characteristics of slug flow, and dimensionless analysis was conducted to investigate the main factors affecting the characteristic length of gas slug. Results show that 1) when the gas flow rate affects the aeroelastic generation characteristics, the aeroelastic characteristic length increases from 443 μm when the gas flow rate increases changes to 657 μm. The generation period decreases rapidly at first and then the change amplitude slows down. The maximum value of aeroelastic generation frequency is 217 s-1; 2) when studying the effect of different liquid flow rates, increasing the liquid flow rate, the characteristic length of the gas bomb gradually decreases, and the generation period of the gas bomb gradually increases. Aeroelastic characteristic length from 770 μm changes to 378 μm. The range of aeroelastic generation cycle is 4–13.4 ms, and the maximum value of aeroelastic generation frequency is 250 s-1; 3) there is a functional relationship between the ratio of aeroelastic characteristic length to channel size L/d and dimensionless gas-liquid flow ratio Q*, Reynolds number Re, Weber number We: L d = 3.677 Q * 0.58 / R e 0.11 .


During a volcanic eruption, large quantities of Sulphur dioxide (SO2) are sometimes emitted into the atmosphere. Rapid detection and tracking ofvolcanic SO2 clouds might be beneficial to air traffic security and to predict any correlated impact on the environment; for example, the possibility of acid rain events. Within the presented work, we exploited Sentinel-5p radiance data (Level 1 b) to detect and retrieve SO2 volcanic emissions through a neural network based algorithmthat produces rapid SO2 vertical column estimates. The dataset used for training the net was composed of 13 TROPOMI Level 2 "Offline" SO2 data collected during the Etna Volcano eruption that occurred in 2018 from 22 December to 1 January. Experimental results are very encouraging and open to the perspective ofmake available a new and stable product for monitoring atmospheric SO2 clouds on a global scale based on Sentinel-5p acquisitions.


In a recent article in the journal RETINA, Querques et al described a case series study of Best vitelliform macular dystrophy. The authors proposed preferential hyperacuity perimetry (PHP) as a mean to assess functional impairment in various stages of the disease. They reported a significant correlation between the morphological severity of the disease and the extent of metamorphopsia (visual distortion of objects) as quantified with PHP. This result is consistent with the working hypothesis that in the early stages of outer retinal disease, photoreceptors are still intact but spatially shifted, such that hyperacuity is affected. Although PHP was specifically developed for early detection of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD), it may be useful for measuring the severity of other macular conditions, such as hydroxychloroquine retinal toxicity and as we learn now also the atrophic stages of Best disease. While the cause and time scales of these macular conditions are very different, their natural histories share one aspect: In at least part of these patients, the first symptoms could begin with metamorphopsia. The use of a psychophysical test such as PHP for early detection of CNV is in a more mature state, compared with other macular diseases. I therefore take this opportunity to review the past, present, and future contributions of PHP in the management of AMD.


Authentication using finger vein pattern has substantial advantage than other biometrics. Because human vein patterns are hidden inside the skin and tissue, it is hard to forge vein structure. But conventional system using NIR LED array has two drawbacks. First, direct contact with LED array raise sanitary problem. Second, because of discreteness of LEDs, non-uniform illumination exists. We propose non-contact finger vein acquisition system using NIR laser and Laser line generator lens. Laser line generator lens makes evenly distributed line laser from focused laser light. Line laser is aimed on the finger longitudinally. NIR camera was used for image acquisition. 200 index finger vein images from 20 candidates are collected. Same finger vein pattern extraction algorithm was used to evaluate two sets of images. Acquired images from proposed non-contact system do not show any non-uniform illumination in contrary with conventional system. Also results of matching are comparable to conventional system. We developed Non-contact finger vein acquisition system. It can prevent potential cross contamination of skin diseases. Also the system can produce uniformly illuminated images unlike conventional system. With the benefit of non-contact, proposed system shows almost equivalent performance compared with conventional system.


LPG (or LP gas) stands for liquefied petroleum gas. Choosing LPG as an energy source represents a valuable contribution to the ongoing fight to conserve energy and protect the environment. The main objective of the present study is to investigate the share of LPG in Turkey's energy sources by presenting its historical development. Since the beginning of the 1960s, LPG has been used as an alternative to city gas and kerosene in Turkey, while the first LPG use in cogeneration plants was in 1996 in Denizli, Turkey. The consumption of petroleum products in 2000 was 34 million tons, of which about 13.2% was accounted for by LPG. Only due to the price, LPG did not reach the desired position in cogeneration applications with a value of under 1%. However, autogas-LPG used as an automotive fuel has rapidly established itself in the country. The role of the government is also crucial for the sustained development of the LPG market in Turkey.
