It is the largest single financial effort in precollege science education reform since the post-Sputnik era of the late 1950s. That's how Luther S. Williams, the National Science Foundation's assistant director for education and human resources, describes $8.6 million in NSF grants to fund a new program that may drastically change the way science is taught. The U.S. Department of Education already has furnished $1.5 million in grants to pilot the program at state and local levels. Curricula for more than a million science students in five states will be affected by the "scope, sequence, and coordination" (SSC) program. If the pilot projects are successful, they could "transform middle level and high school classes nationwide," NSF says. "Students may have completely new science class schedules, with time spent in science courses increased as much as 50%." Six NSF grants, all three-year awards ranging from $1.3 million and $1.5 million, will go to the National Science ...


We study the problem of approximating a surface $F$ in $R^3$ by a high quality mesh, a piecewise-flat triangulated surface whose triangles are as close as possible to equilateral. The MidNormal algorithm generates a triangular mesh that is guaranteed to have angles in the interval $[49.1^o, 81.8^o]$. As the mesh size $e\rightarrow 0$, the mesh converges pointwise to $F$ through surfaces that are isotopic to $F$. The GradNormal algorithm gives a piecewise-$C^1$ approximation of $F$, with angles in the interval $[35.2^o, 101.5^o]$ as $e\rightarrow 0$. Previously achieved angle bounds were in the interval $[30^o, 120^o]$.

Purpose
This paper aims to investigate whether audit fees and financial report readability are bi-directionally related.

Design/methodology/approach
The authors test their hypotheses with empirical data. Specifically, they adopt a two-stage simultaneous equation regression model to assess the bi-directional relationship between audit fees and financial report readability.

Findings
While poor readability increases the fees charged by the auditor, higher audit fees improve the readability of the financial reports.

Research limitations/implications
This study is based on US data. Future research may extend this study to other countries.

Practical implications
Poor financial report readability encumbers stakeholders of the firms. Understanding the interaction between financial report readability and audit fees will help both auditors and firm managers.

Social implications
Audit committees aggressively negotiating for lower audit fees should be aware of the link of low audit fees, potentially indicative of poor quality, to less readable reports. Investors and regulators too should be concerned about this relationship, especially in instances when auditors low-ball audit fees or when firms aggressively negotiate for lower audit fees.

Originality/value
To the best of authors' knowledge, this study is the first to document the bi-directional relationship between financial report readability and audit fees and assess the positive impact of audit fees on financial report readability.


The goal of the study is to investigate the effectiveness of combination of Transcranial direct current stimulation (tDCS) and TENS on pain and functional outcomes in patients with knee osteoarthritis. Study Design: 4-arm parallel group, participant blinded; sham (placebo) controlled randomized trial. Sampling: Simple random Sampling. Sample: 40 patients based on the inclusion and exclusion criteria were recruited and randomized into following four groups: Active tDCS/active TENS (group 1), Sham tDCS/active TENS (group 2), Active tDCS/sham TENS (group 3), Sham tDCS/sham TENS (group 4). Procedure: tDCS 2 mA on M1-SO montage and High frequency TENS at 100 Hz for 20 min for 5 consecutive days followed by supervised exercise sessions for next 5 weeks. Outcome variables: Pain, Six minute walk test and self-reported questionnaire KOOS. Result: Significant pain reduction and functional improvement in Active tDCS/Sham TENS group. Conclusion: tDCS effective in reduction of pain and improving the functions and quality of life. However use of tDCS in isolation or in combination with TENS should be further investigated.


Many solid tumor cancer patients are considered to be at "low-risk" for developing complications even during episodes of neutropenic fever and are routinely managed without hospitalization. Low-risk subsets are now be- ing recognized in patients with hematologic malignancies (CLL/lymphomas) as well. The spectrum of infection in most of these patients is different from that seen in neutropenic patients, with fungal, viral, and bacterial infections primarily associated with defects in cellular immunity predominating. With improvements in supportive care and infusion technology, and the availability of many anti-infective agents for parenteral and oral administration, outpa- tient management of low-risk patients with hematologic malignancies is be- ing practiced with increasing frequency. This approach has several advantages and very few disadvantages but does require substantial initial investment in infrastructure by individual institutions. Nevertheless, it is an investment well worth making by institutions that care for cancer patients, as cancer survivor- ship continues to rise.


In this work, an experimentally validated two dimensional finite element model was refined to predict the solar cell temperature of the novel Concentrating Photovoltaic's (CPV) system. The corresponding 2-D numerical simulation of solar cell temperature for novel concentrating PV system of 10x was presented in this work. Based on the 2-D thermal model, solar cell temperature has been predicted for various boundary conditions. In addition to that, the effects of the ambient temperature and the solar radiation on the solar cell temperature have also been investigated for the proposed CPV system. Based on the influencing parameters of ambient temperature and solar radiation, a separate solar cell temperature correlation has been proposed to predict the cell temperature for the given range of parameters.Copyright © 2010 by ASME


In the paper, it is proved that for any Ahlfors–David s-regular sets E and F in Euclidean spaces, there exist subsets E ⊂ E and F ′ ⊂ F such that dimH E = dimH F ′ = s and E, F ′ are quasi-Lipschitz equivalent.


Abstract Aspects of the ecology of the subalpine tree Hoheria glabrata were investigated a Pegleg Flat, Arthur's Pass National Park. H. glabrata is an early seral tree on recently disturbed sites. Average annual radial increment of timberline specimens was 1.6 mm, and shoot extension growth ranged from 74 mm in mature trees to 151 mm in juveniles. The comparatively high growth rates and vegetative regeneration by epicormic shoots enable the plants to survive extensive mechanical damage and frost damage to growing shoots. The lateral flower buds are produced annually but the subsequent flowering intensity can be reduced by abortion of buds or flowers following adverse climatic conditions. The coccio the dry, lobed fruit are wind dispersed; however most seeds fall close to the parent trees where successful establishment is unlikely. Open habitats with exposed mineral soil or gravel deposits are easily invaded when seed sources are available. Successful germination requires pre-chilling; seeds also germinate...

A general synthesis strategy of using mesoporous SrTiO3nanoparticle catalysts for nitrogen reduction through multiple defects and strain engineering for nitrogen fixation.


This work analyzes the role of processing parameters on the electrical performance of GIZO (Ga 2 O 3 :In 2 O 3 :ZnO) films and thin-film transistors (TFTs). Parameters such as oxygen partial pressure, deposition pressure, target composition, thickness, and annealing temperature are studied. Generally, better devices are obtained when low oxygen partial pressure is used. This is related to the damage induced by oxygen ion bombardment and very high film's resistivity when higher oxygen partial pressures are used. Low deposition pressures and targets with richer indium compositions led to films with high carrier concentration, resulting in transistors with field-effect mobility as high as ∼ 80 cm 2 /Vs but poor channel conductivity modulation, becoming ineffective as switching devices. Nevertheless, it is demonstrated that reducing the GIZO thickness from 40 to 10 nm greatly enhances the switching behavior of those devices, due to the lower absolute number of free carriers and hence to their easier depletion. Annealing also proves to be crucial to control device performance, significantly modifying GIZO electrical resistivity and promoting local atomic rearrangement, being the optimal temperature determined by the as-produced films' properties. For the best-performing transistors, even with a low annealing temperature (150°C), remarkable properties such as μ FE = 73.9 cm 2 /Vs, on/off ratio as 7 × 10 7 , V T ≈ 0.2 V, and S = 0.29 V/dec are achieved.


This paper describes an algorithm that achieves delay and throughput decoupling in distributed fair scheduling in multihop ad-hoc wireless networks. The solution allows to support both low-bandwidth, low-delay and high-bandwidth, high delay applications in a single framework, without wasting much bandwidth to realize the low-delay requirement. We demonstrate the effectiveness of our algorithm in servicing various types of applications through ns-2 simulations.


: In order to ensure that advertising owners can target advertisements and avoid the waste of economy and resources inputs, a scoring advertising equipment based on 3D facial expression recognition is developed in this paper in response to this practical problem. The equipment take pictures separately by the two cameras of two sides, and select the picture with the largest face area for 3D facial reconstruction. It recognizes and classifies the reconstructed 3D facial expression, and then score to judge the user's like level of the advertisement ,and effectively improve the targetedness and promotion affection of the advertisement ,which reduces the cost and improves the efficiency. At the same time, the equipment also designed an efficient cleaning system to solve the problem of automatic cleaning of advertising screen and the scrach of screen.

The spread of the Coronavirus is a challenge for healthcare systems all around the world. The elderly are at high risk for complications from Coronavirus due to low immune system function and underlying diseases. Therefore, the aim of this study was to investigate the causal modeling of Corona anxiety in the elderly based on perceived stress and sense of cohesion with the mediating role of perceived social support. The research method was descriptive, of structural equations type. The statistical population included all the elderly living in nursing homes in Ardabil in 2020, from which 160 were selected using purposive sampling. Used to collect data were Alipour et al.'s Corona Anxiety Scale, Sense of Coherence- 13 scale of Antonovsky, Calhoun et al.'s Perceived Stress Scale, and Zimet et al.'s Multidimensional Scale of Perceived Social Support. Data were analyzed by structural equation modeling using SPSS-23 and Lisrel 8.8 software. Based on the obtained results, the causal model confirmed the relationship between perceived stress, sense of cohesion, perceived social support and corona anxiety in the elderly based on different fitness indices (P<0.05). Perceived stress, sense of cohesion, and perceived social support had a direct effect on corona anxiety in the elderly. Besides, perceived stress and sense of cohesion had an indirect effect on corona anxiety in the elderly through perceived social support (P<0.05). Thus, in the context of the Covid-19 epidemic, it is possible to play an important role in reducing coronary anxiety in the elderly by informing and applying measures to empower the elderly in the areas of perceived stress, sense of cohesion, and perceived social support.


The original S-boxes and algorithms of DES are designed to resist differential attack[11]. We propose eight more new S-boxes with the same cryptographic properties as S-boxes in DES. These 16 S-boxes are used to construct the extended DES, which is double the size of the original DES. The differential and linear cryptanalyses of the extended DES are given. The complexities of the two attacks are found to be 2 and 2 respectively.


We present an ellipsometric study of two Sio._Geo.5/Si strained-layer superlattices grown by MBE at low temperature (500"C), and compare our results with x-ray diffraction (X'RD) estimates. Excellent agreement is obtained between target values, XRD, and ellipsometry when one of two available SixOel_ _ databases is used. We show that dlipsometry can be used to nondestructively determine the number of superlattice periods, layer thicknesses, SizGel_ x composition, and oxide thickness without resorting to additional sources of information. We also note that we do not observe any strain effect on the Ej critical point.


These remarks permit us at last to consider the problems that provide this essay with its title. What are scientific revolutions, and what is their function in scientific development? Much of the answer to these questions has been anticipated in earlier sections. In particular, the preceding discussion has indicated that scientific revolutions are here taken to be those non-cumulative developmental episodes in which an older paradigm is replaced in whole or in part by an incompatible new one. There is more to be said, however, and an essential part of it can be introduced by asking one further question. Why should a change of paradigm be called a revolution? In the face of the vast and essential differences between political and scientific development, what parallelism can justify the metaphor that finds revolutions in both?


The study of cognitive functions in ageing, especially the executive functions in illiterate populations have not received the necessary attention. Studies show a significant increase of risk to develop cognitive impairment or dementia in populations with low level of education and/or illiterate. This increase of cases would be associated with the low capacity of brain and cognition to cope with neurodegenerative processes and which would be mediated by formal educational process. The aim of the study is compare the performance in executive functions in literate and illiterates. A total of 156 older adults were divided into four groups according to educational level: illiterates; subjects with basic and high school and subjects with university degree with the frontal assessment battery (FAB). Our results show significant differences between literates and illiterates in those variables mediated by verbal aspects and inhibitory control mechanisms. We also note that illiterate subjects and with basic school level are significantly different from subjects with higher school level and with university education. These first approximations show us the importance that formal schooling has on brain and functional architecture and opens up a line of promising research that analyzes the role of the executive function in normal and pathological cognitive ageing.

Non-contact displacement and vibration monitoring based on microwave interferometry is an emerging and promising technique in structural health monitoring. This paper focuses on the measurement accuracy evaluation requirements for linear frequency-modulated continuous-wave (LFMCW) radar displacement monitoring in practical applications, and presents an effective accuracy evaluation method based on phasor statistical analysis (PSA). The basic idea of the proposed method is that the phase evolution estimation error (i.e., corresponding to displacement measurement error) can be quantitatively evaluated and calculated by using the relative error statistic of the phasor amplitude tracking result across multiple sweeps. The accuracy evaluation problem and the specific procedures of the proposed PSA method are described. In addition, the detailed mathematical analysis and geometric interpretation regarding three main interference (i.e., noise, static clutter and adjacent clutter) scenarios are provided for the validation. A series of simulations and experiments are carried out to demonstrate the performance of our proposed method, which has low computational complexity, high applicability and good user friendliness.

[1] Magnetic field fluctuations were observed in the data of Voyager 1 on its inbound leg in Saturn's magnetosphere from about 19 to 8.4 Saturn radii, during the interval 7–17 hours before closest approach. These low-amplitude oscillations had the appearance of irregular micropulsations. The wave periods in the spacecraft frame varied between ≈1 and 20 min with a tendency to be inversely correlated with the field strength. An eigenfunction analysis yielding wave propagation direction as a function of frequency showed that at and near peak frequency two distinct types of waves were present, one propagating along field lines (within 30°) usually at the higher frequencies considered, (4–14) × l0−3 Hz, and the other propagating along (the azimuthal direction in a standard spherical coordinate system) at lower frequencies, (0.8–4) × l0−3 Hz. The power spectral density (in (nT)2/Hz) at the peaks tended to be inversely related to frequency over the full set of frequencies. An interpretation of these results is that Alfven waves are propagating along field lines at the higher frequencies with wavelengths between 1/4 and 1/2 RS. These occur in both the mantle and plasma sheet. The waves traveling along , which are observed to occur in the low-latitude plasma mantle, are apparently manifestations of rapidly corotating MHD waves with large compressional components and are probably due to the operation of the centrifugal flute instability at the plasma sheet-mantle boundary. For both types, wave absorption occurs with a high-frequency cutoff at or near the gyrofrequency of O+ (and/or N+). Our results establish the framework for MHD waves within Saturn's outer magnetosphere, and it is expected that the Cassini mission, for which orbit insertion occurred on 1 July 2004, will add considerably to that presented here.

This Jamaican Family Planning (JFP)and Tulane University project compared cost effectiveness of 2 community-based family planning FP distribution methods in rural and semi-urban Jamaica. In treatment area A 7 salaried outreach workers trained prior to this 1984-85 study continued their distribution program in 100 communities 19 of which were semi-urban and 81 rural. In treatment area B 30 community volunteers (paid a monthly incentive of $75 JA) were trained to screen new acceptors resupply continuing users refer women with side effects and supply free pills condoms and spermicides to 156 communities 40 of which were semi urban and 116 rural. A baseline survey of a random sample of 1067 women 15-44 years of ages was performed. 13 months after services were initiated and monitored a followup survey measured levels and methods of contraceptive use sources of supply and reasons for non-contraceptive use. Program achievement was measured by couple months-of-protection (CMP) provided based on service statistic records collected by the outreach workers and community volunteers. 63% of the 80584 CMPs were provided by treatment area A outreach workers with contraceptive use increasing from 46%-59%. Area Bs contraceptive use decrease from 50%-41% was attributed to a termination of some prior outreach services and upgrading of nearby government health centers. The overall cost per CMP was $0.79 US; area A registered $0.76 per CMP whereas area B had $0.84 per CMP. 55.5% of the overall service-related project costs (from total of $80191 US) were incurred by the area A outreach program. The study concluded that volunteer distribution programs are more successful in rural areas where family planning access has been limited. With careful selection of volunteers and good supervision volunteers should be considered where funds are limited.


Social networks provide a framework for connecting users, often by allowing one to find his pre-existing friends. Some social networks even allow users to find others based on a particular interest or tag. However, users would ideally like the option of finding others who share many of their interests, thus allowing one to find highly-similar, like-minded individuals whom we call clones. This functionality would not only be a strong improvement to current social networks, but it could yield interesting research work regarding graph theory and sociology. In this paper we explore a means for finding "clones" within a large, sparse social graph, and we present our findings that concern patterns of shared interests. Additionally, we explore how this correlates with connectivity and degrees of separation. With our introductory work, we hope to encourage future work regarding developing efficient, accurate algorithms for finding clones. In addition, we aim to inspire others to further our data mining efforts toward understanding the relationship between connectivity and having shared interests.


We employ a modification of our previously published method based on multi-atlas label propagation (MALP) and intensity-based refinement through expectation-maximization (EM) to segment magnetic resonance (MR) brain scans of the OASIS database. We had gold-standard segmentations available for 15 subjects of the same database, which we used as atlases in a multi-atlas propagation setup. After propagating the available atlases using transformations obtained with the robust MAPER approach, we use a locally weighted fusion strategy to merge the 15 atlas label sets into a consensus probabilistic segmentation of the unseen image. We use these probabilistic labels as priors in a subsequent EM refinement step, where we improve the segmentations based on the intensity distribution of the images. On top of the common EM refinement we apply a statistical correction based on the intensity characteristics of each individual region. The intensity profile of certain regions and their individual neighborhoods are not suited for an intensity based EM refinement nor a statistical correction. Therefore, we only refine regions for which intensity based refinement is beneficial and obtain a final segmentation by merging the labels obtained through MALP, MALP-EM and the statistical corrected MALP-EM regions. For evaluation, we segment MR brain scans of 20 subjects of the OASIS database.


To say it objectively,the existing of financial risk is inevitable.Financial management demands all kinds of means and measures,which can strengthen the control and dealing of risks.In case of financial crisis,corporations' executives should establish a precautionary analyzing system,make financial analysis regularly,make appropriate financial risk decisions and take different ways to avoid financial risks.


Aim: To explore the longer term blood
glucose self-monitoring outcomes and frequency of monitoring for outpatients
with diabetes type 1 after completion of the Dose Adjustment for Normal Eating
(DAFNE) course. The hypothesis was that DAFNE outcomes would differ according
to frequency of glucose monitoring.Methods: A sequential data-triangulation design
using existing baseline (T0)
and 12-months (T12) DAFNE
course data and interview data from 12 randomly selected participants who had
completed the course two years ago. Results:
Age range was 23 to 70 years with HbA1c 6.1% to 12.6% at T0 and 6.1% to 11.4% at T12.
Comparisons of HbA1c, PAID, HAD subscales anxiety and depression, and covariate data between T0 and T12indicatedsignificant
reductions in the mean depression and PAID scores (both P 0 and T12 was downwards for change in mean blood
glucose level and all survey scales. The proportion of all participants with T12 HbA1c at or below their T0 value was greater than 50% (Proportion
= 69%, 95% CI: 56% - 79%) but only the highest HbA1c tertile group showed a
significant difference (P =
0.003). There was an average decrease in the incidence of hypoglycaemic events
of 0.6 overall: The greatest change was for the high HbA1c tertile with a mean
decrease of 0.8. The interview data suggested that DAFNE graduates experimented
more with food, exercise, and insulin; gained knowledge; learnt personal body
needs; increased awareness of blood glucose level; gained confidence and
improved their quality of life. Conclusions: There was insufficient evidence to
conclude that frequency of blood glucose monitoring influenced metabolic
control. However, people with type 1 diabetes who undertake the less restricted
DAFNE approach to diabetes self-management can improve their quality of life
and glycaemic control.

Conclusion: This research concludes that the prevalence of Nursing Mouth caries in preschool children at Cimahi in 2012 is74.3% or ¾ of the number of samples Examined.


Structural and morphological parameters, together with processing conditions, determine the type of fracture behavior of polyethylene (PE). Long-time brittle failure, which occurs under low stresses and at room temperature, limits the lifetime of polyethylene pipes, which are used for water and gas distribution. To optimize the lifetime of such pipes, it is necessary to apply methods for comprehensive understanding of their structure and fracture properties. For the observation of the failure process, accelerated PENT (Pennsylvania notch test) and FNCT (full notch creep test) tests were used. The structural parameters were characterized by SIS/DSC (stepwise isothermal segregation/differential scanning calorimetry) and "rapid" SIS/DSC methods. The correlation between fracture and structural parameters was found.

We propose a novel method for unsupervised face recognition from time-varying sequences of face images obtained in real-world environments. The method utilizes the higher level of sensory variation contained in the input image sequences to autonomously organize the data in an incrementally built graph structure, without relying on category-specific information provided in advance. This is achieved by "chaining" together similar views across the spatio-temporal facial manifolds by two types of connecting edges depending on a local measure of similarity. Experiments with real-world data gathered over a period of several months and including both frontal and side-view faces from 17 different subjects were used to test the method, achieving a correct self-organization rate of 88.6%. The proposed method can be used in video surveillance systems or for content-based information retrieval.


A key step in the process of isolating microbial natural products is the preparation of an extract from a culture. This step determines which molecules will be available for detection in the subsequent chemical and biological analysis of a biodiscovery pipeline. In the present study we wanted to document potential differences in performance between liquid–liquid extraction using ethyl acetate and liquid–solid extraction using a poly-benzyl-resin. For the comparison of the two extraction protocols, we spiked a culture of Flavobacterium sp. with a diverse selection of natural products of microbial and plant origin to investigate whether the methods were comparable with respect to selectivity. We also investigated the efficiency of the two extraction methods quantitatively, using water spiked with a selection of natural products, and studied the quantitative effect of different pH levels of the aqueous solutions on the extraction yields of the two methods. The same compounds were extracted by the two methods, but the solid-phase extract contained more media components compared with the liquid-phase extract. Quantitatively, the two extraction methods varied in their recovery rates. We conclude that practical aspects could be more important when selecting one of the extraction protocols, as their efficiencies in extracting specific compounds were quite similar.


We present an analysis of radio emissions associated with the April 7, 1997 solar eruptive event. The event consisted of a filament disappearance, a complex two‐phase coronal mass ejection (CME), and a C6.9, 2N flare. At the same time, intermittent type II radio emissions in the frequency range 1‐10 MHz, corresponding to an altitude range of 2‐15 Ro, were observed by the Wind/WAVES radio receiver. Using the onset times and inferred heights and speeds of the radio bursts, we considered both a CME‐driven shock and a flare‐associated blast wave shock as possible causes of the type II radio emissions. We conclude that some of the radio emissions in the WAVES data are associated with each shock. The type II radio emissions associated with the blast wave shock were farther from the sun than any emission of this type that has been reported previously.


Objective – This study uses the Kaleidoscope Career Model (Mainiero & Sullivan 2006a) to determine key sources of motivation for library professionals during their careers and identifies strategies for how library administrators can better retain and inspire their staff.
Methods – The authors adapted the Kaleidoscope Career Model survey tool with permission from Mainiero and Sullivan. The authors used Qualtrics to send out the adapted survey and in October 2019 emailed a call for participation with the survey link to six library electronic mailing lists. A total of 433 participants completed the survey. The authors reviewed the demographic data and charts Qualtrics generated and used an open-coding method to analyze the qualitative responses to open-ended questions included in the survey. First, they read through those responses, identified common words, phrases, and ideas, which became initial codes. Then the authors reviewed the codes and determined themes common in the data. Each author coded and analyzed each question. Those themes then informed the discussion and recommendations shared in this article.
Results – Nearly 60% of respondents identified as being in the Authenticity phase, 15% in the Challenge phase, and 18% in the Balance phase. When asked if they felt supported, those in the Authenticity phase reported the highest overall level of satisfaction, with those in the 47–52 years old cohort experiencing peak feelings of support. The study found that all early career practitioners seemed interested in continuing in a supervisory role. Those older participants in the Balance phase were less interested than those in the other two phases in continuing to supervise. Those in the Authenticity phase identified most strongly with being organizational leaders. By contrast, older participants in the Balance phase did not identify strongly as leaders. Those in the Challenge phase showed strong interest in being leaders at an early age and that interest increased among older cohorts.
Conclusion – This study is the first to analyze sources of motivation for academic librarians during the stages of their careers. When working with librarians who identify with the Authenticity phase, administrators should work with their employees to develop career goals that are extrinsically based, such as what can be achieved through good work rather than striving for a dream position. Librarians in the Balance phase would benefit from early opportunities to develop leadership roles or serve in supervisory roles. These early opportunities better fit with their efforts to prioritize family later in life. Librarians in the Challenge phase are intrinsically motivated to achieve and strive. They may experience disappointment as newer career librarians continue to advance and as they begin to plateau later in life. Leaders must consider the kinds of changes their organization can withstand as they strive to best support and foster the growth and development of all of their employees.


Emotions can drive intergroup behavior, including intergroup violence. We propose that anger, contempt, and disgust (ANCODI) work together in combination to motivate action, devaluation of the other group, and then elimination of their members. We tested the ANCODI hypothesis by examining speeches given by leaders of extreme political groups prior to major events or rallies that either turned violent (e.g., Kristallnacht in Nazi Germany) or did not (e.g., Gandhi's Salt March in India). Three studies assessed these speeches in the year prior to the critical event and coded for verbal and nonverbal emotional and emotional-appraisal content in references to the nemesis group. Amounts of all three of the ANCODI emotions and their precursor appraisals, in text or video, were elevated 3 months prior to violent events, whereas only anger was elevated prior to nonviolent events. These results suggest that leaders using the ANCODI emotions can generate violence against others, and that identifying this combination prior to an event may facilitate interventions to reduce intergroup violence.


The miniaturization of electronic devices with enhanced performance comes at the cost of thermal challenges. When a device fails, it is necessary to analyze and isolate the failure in the device. A non-destructive analysis of the device is always preferred over a destructive one. Apart from being cost-effective, the non-destructive analysis also helps us to perform more than one analysis technique on the same device to verify our conclusion regarding the failure of the device.A well-established and suitable method to investigate the thermal performance of active devices like MOSFETs is the transient thermal analysis. Here, the thermal step response of the system is generated and from this the structure function is calculated. Structure functions are direct models of one-dimensional heat flow. They represent the thermal impedance of a Cauer network and thus represent the thermal signature of the heat path for the physical structure.This work aims to demonstrate the application of transient thermal measurements to various commercially available electronic power packages D2PAK, differing in their power ratings and therefore internal architecture and thus heat path, so they are ideally suited as a benchmark for a to perform a detailed interpretation of the obtained structure functions. Various thermal interface materials are used to vary the overall thermal impedance of the assembly systematically and controllably. X-ray tomography, cross-sectioning and EDX were performed from the same packages to determine the geometrical parameters and the materials included for the construction of a finite element models model. The results of the experimental measurements are validated with the results of FEM to evaluate the interpretation of the heat path signature.

Terrible triad is a severe traumatic injury of the elbow. We report a new variety of this clinical entity originating from a rare combination of injuries, namely the fracture-dislocation of the right elbow. The symptoms are acute ischemia of the hand with neurological damage following a sport accident suffered by a professional rugby player. We treated him surgically after immediate reduction of the dislocation. The short-term monitoring was clinical, while in the medium-term it was radiological and electrophysiological. On the whole, our (clinical, electrophysiological and radiological) results obtained initially, and medium-term during the last consultation, were satisfactory. The objective of this study is to draw attention to this clinical and radiological variety, as well as to its neurovascular complications and to discuss its therapeutic treatment. During the vascular and neurologic exam we should pay attention to and systematically look for neurovascular complications when treating a similar clinical case.


Since 2001/2002 there has been a formidable expansion of annual crops in Uruguay which has determined changes in land use, with a strong expansion of soybeans (Glycine max) under no-tillage. Improperly managed crop production systems can be an important nonpoint source of pollution, accelerating eutrophication of surface waters resulting from nitrogen and phosphorus (P) inputs. Nutrient losses depend on many factors such as climate, soil characteristics and management practices. Thus, the objective of this work was to estimate the annual P loss on a cropping system and to determine the main factors contributing to such losses. Runoff plots were located at the Experimental Station of the National Agricultural Research Institute in Colonia (INIA "La Estanzuela"), Uruguay (34º25´S, 58º0´W) during the period 2013-2014. Plots were under a Vertic Argiudoll soil with 18.5 mg/kg P-Bray I on the first 7,5 cm, a 3% slope and available water content of 92.7 mm on the first 56 cm of soil depth. The rotation established was soybean - fallow/cover crop, non-fertilized for over 5 years. The amount of runoff water was measured for 23 rainfall events and analyzed for soluble P. During that period the soybean yield was similar to the national average yield and the annual P loss was 0.5 kg/ha. Available water, precipitation, maximum rainfall intensity and runoff explained most of the variation in P runoff losses. Rainfall events of high magnitude and intensity on soils with high available water were identified as the events that produced higher water and P runoff. On the other hand, the model that best fitted P losses was just explained by rainfall and runoff (P = - 9.99 + 0.95*rainfall +21.56*runoff; R2=0.73). Overall, our results indicate that these soybean-cover crop systems under no-tillage, on soils with proper nutrient status and non-fertilized for a long time seem to be economically and environmentally adequate management systems.


SUMMARY Differential kinematics is a traditional approach to linearize the mapping between the workspace and joint space. However, a Jacobian matrix cannot be inverted directly in redundant systems or in configurations where kinematic singularities occur. This work presents a novel approach to the solution of differential kinematics through the use of dual quaternions. The main advantage of this approach is to reduce "drift" error in differential kinematics and to ignore the kinematic singularities. An analytical dual-quaternionic Jacobian is defined, which allows for the application of this approach in any robotic system.


In gas flow measurement,temperature and pressure correction is one of important means for improvement of gas flow measurement accuracy.Flow measuring error produced by pressure and temperature drifted off set value is described for direct output flowmeter and differential pressure type flowmeter respectively.In order to offer some concepts of quantity,flow measuring errors produced by pressure and/or temperature under eight extreme conditions are given through some examples.In comparison with combined-unit instruments,pressure and/or temperature correction is easier than it used to be,so correction should be adopted and popularized.Some recommendations are presented.


Bus Rapid Transit (BRT) is a high quality bus based transit system which has been identified by the Ministry of Transport, Sri Lanka as an effective transport solution for urbanized areas. Demand estimation for the BRT is a key element in operational planning as it becomes a primary criterion for selection of vehicles, scheduling of services, determination of fleet size and the design stations etc. This paper illustrates a methodology derived from traffic survey data for the estimation of demand for the proposed BRT corridor from Moratuwa to Pettah on Galle Road.

Comment: The problem that this paper tackles is an interesting one: there has been much debate about whether the so-called 'Terminal Classic' drought represents a coherent interval of climate change across the Yucatan Peninsula, and what dynamics may be responsible for the drought. This paper definitely has potential, but the authors should review additional relevant literature and reframe or expand some of their analyses.

In the 1,3-dipolar cycloaddition, a 1,3-dipole and a dipolarophile interact chemically to produce a five-membered ring. The Huisgen cycloaddition occurs when an organic azide and an alkyne unite to form a 1,3-dipolar cycloaddition that results in a 1,2,3-triazole. 1,3-dipolar cycloaddition is an essential step in the regio- and stereoselective synthesis of five-membered heterocycles and their ring-opened acyclic derivatives. Some of the cycloadducts produced by these reactions were converted into enantiopure precursors known to exist in some biologically active chemicals as well as an active stereoisomer of a pine sawfly sex pheromone. The synthesis of several new enantiopure organocatalysts that were shown to be helpful in some The synthetic utility of these 1,3-dipolar cycloaddition processes with nitrones and a,b-unsaturated aldehydes was further demonstrated. There are times when these reactions have modest to moderate diastereofacial selectivity. the choose actual and nonracemic have improved. Compound collections are created in chemical biology research using the BIOS concept, which draws its inspiration from natural product scaffolds. In BIOS, the primary criterion utilized to develop hypotheses for the design and synthesis of targeted chemical libraries is biological relevance. Because they outline the chemical domains that nature has explored, the underlying scaffolds of natural product classes in particular serve as an inspiration for BIOS because they can be thought of as "trivet can often be achieved if both the azomethine ylide and the dipolarophile are chi privileged


The helical compression spring is calculated in the STAS 7067 standard based on the wire twist tension and considering the type of deformation, fatigue loading and vibration and buckling effect. To avoid recalculation of the values of already calculated parameters, the proposed calculation method uses the same formulas from STAS, but sets out a set of restrictions that must be observed in the design stages. To optimize design, start with material selection, set minimum and maximum forces, also the type of deformation as well as the admissible dimensions.


The main result of this study was that Spraino slide patches did not alter ground contact mechanics during a 180-degree change of direction task. In particular, the lack of a difference in horizontal GRF indicates that the use of the patches does not reduce friction and is therefore not detrimental to performance or mechanical safety. The observation that the EMG signals did not change during pre-contact as well as in a time window representing potential reflex-mediated activity (MEC; <120 ms) further supports the notion that stability was not compromised and that no slipping occurred. A manual screening of all trials confirmed this observation and showed that all subjects made initial contact with the medial side of the shoe. A significant increase in plantar flexor activity during late stance may be related to the push-off which may require higher activity of these muscles due to a different foot alignment. It can be concluded that the use of lateral slip patches may not compromise performance and ankle safety in 180degree change of direction tasks. It cannot be extrapolated if the patches would work in a case where the lateral sole of the shoe catches the ground (Wright et al., 2000) while it remains plausible that a protective effect exists.


Abstract In Hard-Boiled Wonderland and The End of the World, Haruki Murakami plays with the quantum idea of the Many Worlds theory, creating two universes that exist in a state of parallelism – one consisting of the main character's objective/subjective reality, the other being a pre-objective reality that resides within the character's inaccessible subconscious mind. These universes are linked within the purely objective, surreal world of the novel by a series of indexical signs and symbols that point the reader back and forth between the worlds, indicating that they are linked by certain shared subjectivities. What follows here is an exploration of how Murakami's novel works from a semiotic point of view.


It is evident from our findings that oestrous cyclicity was not resumed during 60 days pp in Jakhrana female goats, as progesterone level remained at basal level (£ 1.00 ng/ml) during this period. The ELISA results were further supported by ultrasonographic examination which revealed that post partum uterus regained pre-gravid stage by day 45 pp. Transrectal ultrasonography was confirmed as a reliable tool to determine uterine involution in goats. Thus, the results suggest the possibility of sustaining next pregnancy in Jakhrana goats after 60 days pp. Moreover, based upon these findings, it is clear that interventions are possible by advocating hormonal therapy in order to induce and synchronize oestrus/ovulation at or after 60 days pp from the perspective of augmenting reproductive efficiency.

In an effort to support the implementation of universities, universities need to be supported by a set of facilities and infrastructure. One of the basic and essential facilities are available and a library with adequate service. Libraries who is a supporter of university should be able to play an active role to support the task of universities. The library is a facility or providing a means of reading materials. The purpose of the library itself, especially the college library is to provide information services for learning, research, and community service in order to implement the Tri Dharma College tow. Libraries have a very significant role in the institutions, especially institutions that shelter the college library. With good management, the library will have a positive impact for users it serves. Availability of a wide range of services and knowledge in the college library, will give the user a chance to utilize and develop knowledge independently. Repair image of the library as an institution of professional higher education and provide information services to the campus community will open up the minds of them, that the library can be used as an alternative means that are used to study independently.


SOUTH WALES AND MONMOUTHSHIRE BRANCH. The Subcutaineous Tuberculin Test. A CLINICAL meeting of the South Wales anid Monmouthshire Br anch was held at the Swansea General Hospital on January 27th, Dr. R. J. COULTER being in the chair. Dr. A. CLARKE BEGG read a paper on the value of the subcutaneous tuberculin test in the early diagnosis of pulmonary tuberculosis, anid said this was particularly helpful in cases wlheni no definite physical signs were present. The test should not be employed if the patienit's temperature was above 990 F., if lhaemoptysis had occurred recently, nor in the presenice of serious renal or cardiac disease. The danger of causing extension of tho disease if used witlh these precautions was practically non-existent. Positive results lhad, lhowever, been obtained in syphilis, leprosy, actinomycosis, and possibly inl hydatid cyst. The technique was as follows: rest in bed was enforced for forty-eight hours, with four-hourly temperature readinigs, anid an injectioni was tllen giv-en of 0.001 c.cm. of old tuberculin. If the temperature rose within twenty-four to thirty-six lhours to over 1000 F. the reaction was positive. If this did niot occir an injection of 0.002 c.cm.


Diffusion models excel in image generation but lack detailed semantic control using text prompts. Additional techniques have been developed to address this limitation. However, conditioning diffusion models solely on text-based descriptions is challenging due to ambiguity and lack of structure. In contrast, scene graphs offer a more precise representation of image content, making them superior for fine-grained control and accurate synthesis in image generation models. The amount of image and scene-graph data is sparse, which makes fine-tuning large diffusion models challenging. We propose multiple approaches to tackle this problem using ControlNet and Gated Self-Attention. We were able to show that using out proposed methods it is possible to generate images from scene graphs with much higher quality, outperforming previous methods.

Abstract : The report details the successful application of e.p.r. spectroscopy to the study of vanadium(IV) oxohalide complexes. In particular, it has proven an invaluable structural tool for relating the structure of a complex in an amorphous or polycrystalline sample to that of the same complex in solution. Moreover, solution studies by e.p.r. have revealed previously unsuspected dissociation and displacement phenomena for complexes of the type (VOX2Ln) (X=C1 or Br, L=mono- or bi-dentate ligand), which means that many literature reports need to be reexamined. A comprehensive literature survey is included. (Author)


What is the nature of obligations between adult children and older
parents in contemporary Europe? What is seen as the proper balance of
responsibilities between the family and the welfare state, and from whom
would people themselves prefer long-term care if they should come to
need it? These questions are explored in a survey among representative
urban samples of persons aged 25+ in five countries: England, Germany,
Spain, Israel and Norway. Filial obligation norms seem prevalent in all five countries, but to varying
degrees. Country differences are even greater in the more concrete
opinions about how such norms should be enacted, and then in a
direction that is congruent with national policies and opportunities. Filial
obligations need not imply that the family is seen as the natural care
provider, in fact preferences for services are in general higher than the
actual service rates are, implying an unmet wish for more governmental
responsibility. The variation in norms and opinions seem otherwise to
follow somewhat different logics, implying that findings from one country
can hardly be generalised to countries with other family traditions and
welfare state regimes.


We present the results from a Submillimeter Array survey of the 887 μm continuum emission from the protoplanetary disks around 95 young stars in the young cluster NGC 2024. Emission was detected from 22 infrared sources, with flux densities from ∼5 to 330 mJy; upper limits (at 3σ) for the other 73 sources range from 3 to 24 mJy. For standard assumptions, the corresponding disk masses range from ∼0.003 to 0.2 M ⊙ ?> , with upper limits at 0.002–0.01 M ⊙ ?> . The NGC 2024 sample has a slightly more populated tail at the high end of its disk mass distribution compared to other clusters, but without more information on the nature of the sample hosts it remains unclear if this difference is statistically significant or a superficial selection effect. Unlike in the Orion Trapezium, there is no evidence for a disk mass dependence on the (projected) separation from the massive star IRS 2b in the NGC 2024 cluster. We suggest that this is due to either the cluster youth or a comparatively weaker photoionizing radiation field.

Cloud Storage is a branch of Cloud Computing, which plays an important role in IT world. Cloud providers are providing a huge volume of storage space as per the user needs. Due to wide usage of this, it also increases data security issues and threats. Hence efforts are being made to encrypt the data stored in the cloud. In this paper, we are going to look at different encryption and auditing techniques that are used to avoid data breaching in cloud storage.


The book On Intelligence written by Jeff Hawkins proposes a theory of how intelligent behaviour is generated in the brain's neocortex. The underlying mechanism is based on a layered structure called the Hierarchical Temporal Memory (HTM). Researchers have been reporting software and hardware implementation of the HTM, with different levels of success. This paper presents a pattern recognition system based on Hawkins' concept of simple concatenation, where decisions are made based on the processing of information in a hierarchical array of cells. A two-layer network recognizing 32×32 pixel patterns was used as a proof of concept. In this implementation patterns on the upper layer are activated by concatenating patterns presented on the lower layer. The input pattern is analysed in the lower layer by moving a coincidence array. Outputs from the lower layer are fed to the higher layer where they are analysed with a bigger coincidence array. The results in this paper were obtained using a set of seven patterns. One of the patterns was used as a sample or learnt pattern, and the rest of the patterns were used for testing. The efficacy of the network was measured using the percentage of similarity between testing patterns and the learnt pattern. Two different ways of moving the coincidence array were explored. The first method moves the coincidence array by its size, and the second moves the coincidence array by one pixel at a time. For validation, results were also compared to the existing k-nn algorithm and human classification. Moving the coincidence array by one pixel produced a percentage of similarity closer to the results of k-nn, while moving the coincidence array by its size produced a classification closer to the human perception.


Probabilistic seismic capacity analysis (PSCA) plays an important role in the field of seismic performance evaluation, seismic reliability analysis, seismic fragility analysis, and seismic risk analysis of civil engineering structures. In general, PSCA has two levels of research context: global PSCA and local PSCA. The local PSCA has been studied by numerous research programs; however, the global PSCA has just recently been paid attention to in the field of earthquake engineering and structural engineering. In this paper, in order to build global probabilistic seismic capacity model (GPSCM) of structures considering random system properties, a stochastic pushover analysis (SPA) method is developed, which combines four kinds of approximating methods for estimating statistical moments of complex random function with deterministic pushover analysis. The four random analysis methods include mean value first order second moment (MVFOSM) approach, Monte Carlo simulation (MCS) approach, improved point estimation approach, and Zhou-Nowak numerical integration approach. The methodology proposed is applied in R.C. frame structure. A three-bay and five-storey plane R.C. frame is taken as an example in case study, the global seismic capacity curves of the structure corresponding to four levels of limit states are derived. It is demonstrated by this example that the approach proposed in this paper is an efficient and accurate tool for global probabilistic seismic capacity analysis of structures.


Serum levels of total high-density lipoprotein cholesterol (HDL-C) and its subfractions (HDL2-Cand HDL3-C) were measured in 227 healthy Japanese adults. These values were related to a number of lifestyle factors.On co-variance analysis, alcohol drinking had an independent contribution to HDL-C and HDL3-C (p<0.05) in males. Cigarette smoking showed no association with subfractions of HDL-C in males. Three physical activities-sport, work and leisure time activity-had no significant association with subfractions of HDL-C. The degree of obesity as expressed by body mass index (BMI) was significantly negatively related (p<0.05) to HDL-C and HDL2-C levels among females. Among males, although a trend test showed no statistically significant relation to BMI, HDL-C and HDL2-C levels were significantly higher (p<0.05) in the normal group (20≤BMI<25) than in the obese group (BMI≥25).

Abstract Category: 16. HypertensionSession-Poster Board Number: 1047-296Authors: Toshiyuki Nagai, Toshihisa Anzai, Hidehiro Kaneko, Yoshinori Mano, Atsushi Anzai, Yuichiro Maekawa, Tsutomu Yoshikawa, Keiichi Fukuda, Keio university school of medicine, Tokyo, JapanBackgrounds: Serum C-reactive protein (CRP) elevation predicts the development of cardiovascular disease in patients with hypertension. CRP activates macrophage and enhances oxidative stress. We hypothesize CRP itself has a pathogenic role in the development of pressure overload-induced cardiac remodeling through enhanced inlammatory response and oxidative stress.Methods: Transgenic mice with human CRP overexpression (Tg) and wild type mice (W) were subjected to transverse aortic constriction (TAC/Tg, TAC/W) and sham operation (Sham/Tg, Sham/W).Results: One week after operation, TAC mice showed left ventricular (LV) hypertrophy compared with Sham mice, but no signiicant differences between TAC groups. However, in TAC/Tg, myocardial mRNA levels of interleukin (IL)-6, CD68, glutathione peroxidase-3 (GPx3), 47-kDa -subunit of nicotinamide adenine dinucleotide phosphate oxidase (p47phox), collagen I, and the number of iniltrating Mac-2+ macrophages and nuclear factor-kB/p65+ cells were increased than those in TAC/W (all p<0.01). Cardiac ibrosis (% area fraction [AF]) was more prominent in TAC/Tg compared with TAC/W (p<0.05). Four weeks after operation, heart and lung weights were increased in TAC/W than in Sham/W, and these differences were further augmented in TAC/Tg (p<0.01, p<0.05, respectively). LV fractional shortening was lower (p<0.0001) and LV end-diastolic pressure was higher (p<0.05) in TAC/Tg than those in TAC/W. Myocardial mRNA levels of angiotensin type 1 receptor, atrial natriuretic factor, p47phox, GPx3, IL-6 and collagen I, protein level of transforming growth factor-beta1, and the number of iniltrating Mac-2+ macrophages were increased in TAC/Tg than those in TAC/W (all p<0.05). Cardiomyocyte cross sectional area and the AF were greater in TAC/Tg than those in TAC/W (p<0.001, p<0.05, respectively).Conclusions: Continuous overexpression of human CRP in mice adversely affects pressure overload-induced cardiac remodeling preceded by enhanced inlammation and oxidative stress.CRP plays a pathogenic role in cardiac remodeling and could be a therapeutic target for the treatment of heart failure induced by pressure overload.


MORALES VALVERDE, R. (1991). The genus Micromeria Bentham (Labiatae) in the Iberian Peninsula and the Balearic Islands. Anales Jard. Bot. Madrid 48(2): 131-156 (in Spanish). The Iberian and Balearic species of Micromeria were studied taxonomically, incorporating chemical, palynological and karyological data. Six species inhabit the geographic area considered; three of them are found in the Peninsula and five of them are present in the Balearic Islands. The peninsular species are M. fruticosa (L.) Druce, M. inodora (Desf.) Bentham and M. graeca (L.) Bentham ex Reichenb, subsp. graeca. The Balearic species are M. inodora, M. graeca subsp. graeca, M. nervosa (Desf.) Bentham, M. microphylla (Dum. d'Urv.) and M. filiformis (Aiton) Bentham, this last one an endemism of these islands. M. juliana is considered an introduced species which now grows wild in the area around Coimbra. The chromosome number for M. fruticosa has been determinated for the first time (2n = 22). Pollen studies were carried out, which had been lacking previously for several of these species. Scanning electron micrographs are included. Previously unpublished data on chemical analyses of essential oils present in M. fruticosa, M. inodora, M. graeca and M. filiformis are also presented. Nomenclatural types are chosen for M. fruticosa, M. inodora, M. graeca, M. nervosa and M. juliana. Each species is accompanied by a drawing and a distribution map (UTM projection) with points equivalent to 10 x 10 km quadrats. A provisional list of those species present in North Africa is provided, and the following new combinations proposed: Micromeria arganietorum (Emberger) R.

The classical triangle Schwarz functions D(ν0, ν1, ν∞; z) are defined as quotients of two linearly independent solutions of Gauss' hypergeometric differential equations. If their angular parameters ν0, ν1, ν∞ are real and have absolute value in the open interval ]0, 1[ , they define biholomorphic mappings of the complex upper half plane H onto triangles in the Riemann sphere bounded by circular arcs. The singular points 0, 1,∞ of the differential equation are sent by D to the vertices of the triangle including there angles π|ν0|, π|ν1|, π|ν∞| , respectively. Particularly interesting special cases are those where ν0, ν1, ν∞ are the inverses of positive integers p, q, r because then D is the inverse function of an automorphic function for the triangle group with signature 〈p, q, r〉 , isomorphic to the (projective) monodromy group of the hypergeometric differential equation. The present paper considers the question if triangle Schwarz functions can have algebraic values at algebraic arguments. The problem has its origins in the natural general question if or under which conditions (suitably normalized) transcendental functions have transcendental values at algebraic arguments, and in this special context it is related to automorphic functions and periods of abelian varieties. For a general survey about algebraic and transcendental periods in number theory see Waldschmidt's recent article [Wa]. In the cases related to automorphic functions mentioned above the problem is treated already in our previous paper [SW] (Cor. 5). It turned out that a positive answer is directly related to the condition if certain Prym varieties are of complex multiplication (CM) type, the Pryms being defined in a natural way via the integral representation of the associated hypergeometric functions. Now we generalize the setting and consider arbitrary rational angular parameters ν0, ν1, ν∞ , restricted only by some mild technical condition excluding logarithmic singularities and some other very special situations. The main results will show that we have still 'CM' as necessary condition for 'algebraic values at algebraic arguments', but that even under the CM condition this algebraicity is rather exceptional. However, we will give examples that such exceptions occur. This more general type of triangle functions has still images of H bounded by parts of circles but they are in general not globally biholomorphic — the image domains may overlap. We treated in [STW] an analogous problem admitting apparent singularities in the associate Fuchsian differential equations. The triangle functions of the present paper may in fact be considered as limit


Hydro turbine is the most critical component in small or micro hydropower plants as it affects the cost as well as overall performance. Hence, for the cost effective design of any new small or micro hydro project or for energy recovery plant from existing water infrastructure, it is very important to predict the hydraulic behaviour and efficiency of hydro turbine. Experimental approach of predicting the performance of hydro turbine is costly and time consuming compared to CFD approach that saves time-cost-effort. The aim of the paper is to predict the performance of a micro hydro turbine (MHT) using Solidworks-FloXpress (CFD analysis) and to validate the same with model testing results. To the best of the author's knowledge this novel approach for CFD analysis of micro hydro turbine for energy recovery from drinking water pipeline is absent in renewable energy or fluid mechanics literature due to its assessment complexity.


The aim of the research is to investigate activation of antitumor immune response efficiency using professional antigenpresenting autologous dendrite cells in the complex treatment of patients with cerebral hemisphere malignant gliomas. We have analyzed 55 cases of patients with malignant gliomas (41 glioblastomas, 14 anaplastic astrocytomas) who received a complex treatment with specific immunotherapy use. All the patients were hospitalized at Late stage of disease and tumor size exceeded 5 cm. Specific antitumor immunotherapy was conducted in accordance with original methodic, including autologous dendrite cells with tumor antigens and tumor cells lysate. Treatment course included intradermal introduction of dendrite cells at the 10-12 day after the operation. The treatment included not less than 3 injections. The course of treatment was repeated every 2-3 months. The immunological status was tested before and after courses of immunotherapy. Specific antitumor immunotherapy included into complex treatment of malignant gliomas allows to increase disease remission, life quality being satisfactory.


ABSTRACT This study aimed to investigate the role of ongoing relationships with the deceased in facilitating posttraumatic growth among suicide-loss survivors. The sample comprised 58 suicide-loss survivors, 48 sudden-death, and 53 natural-death bereaved individuals, who completed questionnaires assessing the two-track model of bereavement, grief, and growth-related characteristics. Suicide-loss survivors reported lower levels of positive relationships with the deceased than did the other groups. An interaction was found between relational-active grieving and type of death in predicting posttraumatic growth. The study concluded that intense grief along with preoccupation with the deceased lessened positive personal transformation, especially among those struggling with a loved one's suicide.

A low-voltage controller-based all-digital phase-locked loop (ADPLL) utilized in the medical implant communication service (MICS) frequency band is designed. The controller-based loop topology is used to control the phase and frequency for reliable handling of the ADPLL output signal. The digitally-controlled oscillator with the delta-sigma modulator is employed to achieve high frequency resolution. The phase error is reduced by the phase selector with 64-phase signal from the phase interpolator. Fabricated in a 130-nm CMOS process, the ADPLL has an active area of 0.64 mm2. It consumes 840 μW from a 0.7-V supply voltage and has a settling time of 80 μs. The measured phase noise is -114.6 dBc/Hz at 200 kHz offset frequency.


This paper puts forward a typology of pragmatic functions which differs in some basic respects from the ones proposed so far in the Functional Grammar literature by Watters (1979), Dik et al (1981), de Jong (1981) and Dik (1989). In the first place, it is argued that a distinction between unmarked and marked pragmatic functions contributes to the typological adequacy of the theory. As regards intra-clausal pragmatic functions, four possible criteria of markedness are revised: lexical category, type of information, assignment of syntactic function and the order of clause constituents. The pragmatically-governed syntactic alignment of clause constituents that includes the syntax-phonology mapping is selected as the most accurate criterion for pragmatic function markedness. With reference to extra-clausal pragmatic functions, the marked status of the topic as theme and of the tail as focus are discussed.

In an adult skull assigned to the student loan collection of this University there is a straight canal extending nearly vertically through the body of the sphenoid bone. It opens superiorly as an oval pit (1 x 1.5 mm), situated midway in the liypophyseal fossa of the sella turcica and lying in the midplane (fig. 1). The inferior end lengthens into a groove (8.5 mm) just behind the rostrum of the sphenoid, the forward limit of the groove lying between the alae of the vomer (fig. 2). Chiseling or a cleverly executed saw-cut will expose the conrse and relations of such a canal (cf., fig. 3). Although this anomalous passage has been called the craniopharpngeal canal and is well enough known to be mentioned in text books of gross anatomy and embryology, the uccumulated facts concerning it have never been brought together in a compreliensive manner since tlie now outdated contribution by Sokolow in 1904. Rather than to describe in further detail the specimen at hand or to add to the extensive statistical studies already made, it is proposed to summarize and synthesize the existing information that has been presented from time to time in individual publications. The period thus reviewed is nearly a century. In addition, a reinterpretation of the canal will be made, based on a study of the regression of the stalk of Rathke's poncli and


A new approach to defence capability planning is proposed. The authors adapt Boulding's general systems hierarchy to a range of defence systems and 'systems of systems', using the systems' capacity to handle data, information and knowledge as the key discriminator. 'Systems' of capability planning are of the highest complexity. The design of a new approach centres on a process with a capacity for single-loop and double-loop learning, to provide a foundation for shifting Defence from its current, short-medium term planning paradigm that is locked into single-loop learning. The design for doubleloop learning integrates a systems approach to address Defence's high-level need from the 'system' of capability planning namely, formative guidance on Defence future directions. The paper closes with a note on leadership and measures to drive the development of 'adaptive' behaviours essential for designing adaptive force structures.


It is shown that a static VAR generator comprising a capacitive filter network and a thyristor-controlled inductor can effectively compensate for rapid and unbalanced load variations and is able to maintain system voltage and power factor, even under extremely adverse load conditions. The performance of such a static compensating system is, however, dependent on the principles of control employed, the adequacy of the VAR rating, and the electrical characteristics of the filter network. In arc furnace applications, the VAR generator must be rated for unbalanced load conditions and the capacitive filter network must be designed to be compatible with the ac system impedance, and with the spectrum of the furnace current that contains both odd and even harmonics.


Islamic domestic courtyard diffuses in many varieties throughout all Islamic countries extending from Arabian Gulf to Atlantic Ocean and towards Pacific Ocean; and has undergone a complex development throughout history. This house typology is a significant phenomenon in the aspect of cultural, environmental, structural and most importantly religion. In Islam, house is not only a place of shelter and rest but also a center where family members can learn, teach, practice and further propagate the teachings of Islam. Through the study of Islamic teachings and architectural knowledge, a house can be designed so that it is capable to play a vital role in enhancing Islamic way of life among its inhabitants. In view of this subject, one of the fundamental functional spaces which should be integrated to the house design is courtyard. Courtyard is an essential entity that was built to moderate complex climatic conditions and to deal with complicated issues in Islamic teachings, for example in subjects of privacy and efficiency. Among the attributes of domestic courtyard are introverted orientation (privacy), space organizer, transitory space, climatic moderator and multi-functional space. These attributes contribute considerably to the house entity in fulfilling its roles and functions as a focal point of Muslims to inculcate divine principles into their lives. This paper intends to elaborate on the attributes of domestic courtyard and analyze important subjects in Islamic teachings pertaining to domestic living. Further, Oman, a country that enters to the fold of Islam at its early advent (2nd year Hijrah), with its unique courtyards houses is used as a case study for this research in order to analyze courtyard typologies and its role in the Islamic teaching and practice.


In this paper, the effect of dispersion on sensing parameters of a racetrack resonator-based biosensor is studied. It is shown that dispersion has a significant effect in biosensing characteristics of a resonator designed with silicon-oxy-nitride (SiON) waveguides in a racetrack configuration. Based on the results, high sensitivity (S) can be achieved using a SiON racetrack resonator as a biosensing device. Simultaneously, this device has a high total quality factor (Qt). The highest S for a transverse electric whispering gallery mode (TE WGM) of 1 (2) is found to be 87.82 (434.94) nm/RIU at an optimized resonator radius of 69 μm (19 μm). At the same time, the highest Qt factor of ∼4.6×104 is obtained for TE WGM 1 and 2, at biological cladding. These amounts of S and Qt factors result in an ultrahigh figure of merit (FOM) of 4766  RIU−1 and 23705  RIU−1, respectively, for TE WGM 1 and 2. Based on the FOM calculations, our sensor structure performs 237 orders of magnitude better than surface plasmon resonance devices for bulk refractometric sensing. Device analysis is done by simple, fast, and reliable analytical methods. The model results are validated through comparison with experimental reports.


Some ultrahigh molecular weight polyethylenes have been shown to be highly ductile but only under specific conditions. When the initial starting state is reactor powder, the ductility is presumed to be due to the low initial entanglement. Samples were prepared for such draw by compression molding of reactor powder that had been held at different temperatures in the melt for only brief periods (5 min), followed by cooling to room temperature. These films were then quickly heated and drawn at a constant temperature of 140−155 °C, above the static melting temperature (Tm ≈ 135 °C). The stress/strain behavior from this state was found to be significantly influenced by both the prior melt temperature and the time needed for preparation of the initial morphologies. X-ray diffraction showed that the strain-induced crystallization from the melt had occurred during draw above a critical strain, corresponding to the draw ratio of ∼10. Differential scanning calorimetric data clarified that the rate of this crystalli...


The abundance of phytoplankton,zooplankton and benthos and water quality factors were observed and analysed in super-intensive and semi-intensive farming ponds in this study.The results showed that the number of phytoplankton(22 815 inds/ml 31 590 inds/ml),zooplankton(490.5 inds/L 650.0 inds/L)and benthos(4.5 inds/10 cm2 267.5 inds/10 cm2)were higher in semi-intensive farming ponds than super-intensive ones;but DO,NH_4-N and PO_4-P concentrations were just contrary to above indexes.Shrimp growth,growth rate and survival rate in super-intensive farming ponds were lower than those in semi-intensive farming ponds,but super-intensive farming could gain higher production for super-intensive farming density was much higher than semi-intensive farming one.


This paper focuses on small and medium-sized companies who have received support from the government for development work. All companies acquired a new resource, but the situations were found to differ in terms of how the new resource was fitted into the existing resource collection. In this paper, three such situations are analysed, and a taxonomy for classifying such situations is suggested.


When the Apollo program was over, the items that were returned to Earth became treasures to be shared with the American taxpayers who funded this great adventure and with people from around the world. The space suits are the only life-support equipment that was taken to the moon's surface and brought back to Earth. That we have relatively few items back from lunar missions makes the preservation of equipment and moon rocks all the more important. Fortunately, America has some of the best museums in the world. The Smithsonian's National Air and Space Museum, located on the Mall in Washington, DC, began as the National Air Museum in 1946. Funding for the present building was approved in 1971 and the museum opened its doors on July 1, 1976.


Throughout time and across all cultures, music and sound have been an integral part of ceremony, ritual, and healing. In every cosmology and mythology sound is a major link, the carrier wave between the world of the spirit and the people of Earth ... Today, we know ... when we listen to music or hear certain sounds that it evokes powerful emotions that can pump us up, make us sad, or help us to understand and express our feelings (Sound Therapy).


A recent report published by the Health Protection Surveillance Centre (HPSC) shows that the prevalence of HIV infection among women who availed of antenatal screening between 2002 and 2008 ranged between 2.0 and 3.3 per 1,000 women tested. The prevalence rates have remained stable at 2.0 per 1,000 women tested in 2007 and 2008 which is a decrease from the rates seen in 2002 and 2003 which were 3.2 and 3.3 per 1000 respectively. In Europe, the prevalence of HIV among pregnant women remains low, and during the period 2000 to 2004, no country reported to EuroHIV a national prevalence among pregnant women of greater than 5 per 1000 tested.1 In this period, the highest national prevalence of HIV in countries reporting data to EuroHIV was 4.8 in Estonia (2002), 3.4 in Ukraine (2004) and 3.1 in Ireland (2003).1 In the other 20 countries reporting to EuroHIV, HIV prevalence was consistently less than 3.0 per 1000 tests.


Mobile sinks in wireless sensor networks require an additional communication mechanism of geographic routing. Because the sink's location as the destination in geographic routing is changed dynamically, sinks' location should be propagated continuously though the sensor field for sensor's future data report. However this frequent location updates can drain up the sensor's battery power and increase wireless channel contentions. As a support to the mobile sinks, we proposed locators for mobile sinks that track current sinks' location. If a sensor reports sensed data to sinks later, it can acquire sinks' location from the locators. The locators are uniformly distributed uniformly to the sensor fields by hash bashed structured replication. Sinks update own location only immediate locators and other locators are fed location information by locators self location propagation. We implemented our locator protocol with network simulator-2 and compared previous work TTDD, a two-tier data dissemination. Our results show that locators handle multiple source environments with low overhead of location acquisition process


On September 30, 2005, the Danish newspaper Jyllands-Posten printed 12 editorial cartoons, several of which contained caricatures of the Islamic Prophet Muhammad. This publication sparked a controversy that began in Denmark and spanned the globe. The cartoon publications stemmed from an article discussing the difficulty in finding illustrators for a book on the life of the Prophet Muhammad. According to the book's author, cartoonists refused contract out of fear of retaliation from the Muslim community, citing the example of the 2004 murder of Theo Van Gogh, a Dutchman, for making the documentary Submission, a film focused upon the position of women in Islam. In addition to the article, nationwide debate discussed the right to freedom of speech and the problems surrounding self-censorship. It was within this context that Flemming Rose, the cultural editor at Jyllands-Posten, asked Danish cartoonists to depict the Prophet Muhammad as they saw him with the underlying purpose to raise the issue of self-censorship and fuel further debate. The cartoons ran alongside an article on free speech and self-censorship.
