The title refers to those who worked for the merger of the Congregational Christian churches and the Evangelical and Reformed church between 1950 and 1957, but who took a moderate, mediatorial role in attempting to avoid further schism on the road to union. Henry D. Gray was the chairman of the Committee on Congregational Polity (1950-1954) and a member of the Constitutional Commission (1954-1956) and was thus highly instrumental in the movement, but he finally rejected the merger as advanced by the Executive Committee. His extremely detailed chronicle of this ecumenical labor is of historical value primarily because it reproduces a vast number of his letters, memoranda, sermons, and committee minutes. The volume will be of interest to members of both the United Church of Christ and the Congregational Christian churches for the interpretation of events it offers from an insider's perspective. The introduction of different type fonts within quoted materials is an irritating method of organization and, combined with the author's lack of selectivity, contributes to some confusion. But despite the excessively fulsome reporting and the journalistic style, this volume must be referred to for many otherwise unavailable documents of the union.


With the gap in petroleum supply and demand increasing and the dependence degree going on highly,it is important of us to increase the investment abroad of oil and gas which is for taking full advantage of international oil and gas resources,and developing foreign cooperation.With the large function of Africa in the world energy market and rising of the geopolitical position,together with the traditional friendship and cooperation opportunity between Africa and China,it is quite important and pressure of us to invest oil and gas resources in Africa.

This manuscript uses an ensemble model which combines four machine learning models, namely KNN (K-Nearest Neighbors Algorithm), Deep LSTM (Long Term Short Memory), SVM (Support Vector Machine), and Decision Tree to detect instability and fall of the human percept under observation. On detecting a fall, a quick call and message are sent by the system via Twilio API (Application Programming Interface) to the registered care provider for immediate first aid and treatment. An appropriate system has been simulated and tested to verify the reliability and robustness of the proposed model. Details of the same have been laid in the manuscript. This will thus ensure that the injured person will get the treatment on time.


This paper studies the consensus problem of multi-agents system with communication management. Communication management means a strategy about how to adjust the sensing range of agents in the consensus process for saving communication energy. We propose a communication management for multi-agents system with second-order dynamics so that with this strategy, different control methods can be applied and the designing work is simplified. And a predictive control method is presented to solve the consensus problem of multi-agents system with the communication management in this paper. Simulation results indicate the effectiveness of the predictive control method and the benefits for solving this problem.

ABSTRACT - The objective of this work was to study the effects of the concentrate levels of the diet on the microbial efficiency, rumin alammonia and pH, and endogenous nitrogen (N) losses. Four Nellore bulls, fistulated in the rumen, abomasum and ileum, were full fed dietswith 25.0, 37.5, 50.0, 62.5, and 75.0% of concentrate and allotted to a randomized block design. The ruminal ammonia concentrat ions and pHwere measured in the ruminal fluid samples in collections made before and 2, 4, 6 and 8 hours after the feeding. The maximum m icrobial efficiencyof 28.62 g Nmic/kg OMDR was estimated with 48.86% of concentrate level of the diet. The efficiencies expressed in g Nmic/kg CH ODR andg DMmic/kg CHODR, however, showed negative linear effect, while the efficiency expressed in g CPmic/100 g TDN was in an averag e 9.42.The estimated values for metabolic fecal nitrogen, the urinary endogenous N, and total endogenous N losses were, respectively, 5.17 g/DMintake, 389 mg/kg .75 , and 260 mg/kg


Understanding the mechanisms through which the momentum and Reynolds stresses are redistributed in strongly curved bends is directly relevant for flow in natural river configurations. In this paper, Detached Eddy Simulation (DES) is used to calculate the flow and turbulence structure in a single open channel 193 bend of very high curvature for which the ratio between the mean curvature and the channel width is close to 1.3. For these conditions, the strength of the cross-stream motions and anisotropic effects are very important. This makes it a very tough test case for numerical models. The threedimensional velocity distributions predicted by DES are compared to the data obtained from an experiment conducted at EPFL-Lausanne. Results show that DES satisfactory capture the distribution of the streamwise velocity in the mean flow and, more important, the distribution of the streamwise vorticity in relevant cross-sections. Comparison with Reynolds Averaged Navier Stokes (RANS) simulations shows that DES is significantly more successful in predicting the velocity redistribution in the channel as a result of the non-linear interactions between the main flow and the cross flow induced by the channel curvature. The success of DES is particularly important, as this technique can be used to conduct numerical simulations at Reynolds numbers close to those present in the field, thus allowing the study of scale effects.

Unitarity of evolution in gravitational collapses implies existence of macroscopic stable horizonless objects. With such objects in mind, we study the effects of anisotropy of pressures on the stability of stars. We consider stars in four or higher dimensions and also stars in M theory made up of (intersecting) branes. Taking the stars to be static, spherically symmetric and the equations of state to be linear, we study "singular solutions" and the asymptotic perturbations around them. Oscillatory perturbations are likely to imply instability. We find that nonoscillatory perturbations, which may imply stability, are possible if an appropriate amount of anisotropy is present. This result suggests that it may be possible to have stable horizonless objects in four or any higher dimensions, and that anisotropic pressures may play a crucial role in ensuring their stability.


In order to know the disseminative effect of Olympic Culture in universities and how well the students who major in Sport understand it.By applying the following methods of survey:literature search,questionnaire,visit by inquiry,mathematical statistics,this thesis conducts a questionnaire research aiming on 470 sport students of Beijing Sport University,making a comparison between ordinary university students and professional sport students and revealing the findings:students major in Sports are able to identify Beijing Olympic Game well and they are confident of the intercultural communication of the emblem.However,these 470 students do not catch a full and deep understanding of the meaning of emblem, furthermore,in terms of the concern and recognition of Olympic Emblem,they are not allowed to be pessimistic.The above conclusions indicates that the course offered of universities and colleges have much room for improvement,the activities focusing on communicating Olympic Culture in campus are not able to popularize the knowledge of Olympics among sport students successfully.The author proposes that reinforce the dissemination of Olympic Culture in campuses and improve the system of curriculum regarding on Olympic Culture.In this way,it will provide students major in sport with an effective platform,helping them to comprehend the Olympic Culture initially and enhance their cultural accomplishment.


This paper introduces an evolutionary/systematic hybrid which combines the concept of evolutionary hill-climbing search with the systematic search concept of arc revision to form a hybrid that quickly find solutions to fuzzy constraint satisfaction problems. This hybrid outperforms a modified version of a well known hill-climber, the iterative descent method, on a test suite of 500 randomly generated fuzzy constraint networks.


The change in fertility rates is a trend that occurs in almost everyone except the poorest regions of Africa. The process of demographic transition began in European countries and spread across the planet. So this is a trend which is also found in Brazil, where the fertility rate is 1.95 children per woman according to the latest data from the IBGE. These changes are generally related to increased schooling, greater female participation in the labor market, increased access to contraceptive methods, increasing the cost of raising children and changing cultural values in relation to the number of children. In this context the present work searches to characterize the reduction of the fecundity in Aracaju and its main impacts, with the objective to detail the process, also disclosing the reality for quarters of the capital.


of an almost pathological sense of "cosmic kingship" indicates one of the strengths of Anderson's book: his willingness to engage in complicated historical inquiry. While he sticks closely to his theme, he is always aware of the dangers of essentializing or creating too smooth a narrative. As he puts it, his book "focuses as much on differences as on similarities, as much on antagonism as on common ground" (8) in a worthy attempt to complicate the picture of the early Middle Ages. In his conclusion, Anderson notes the intellectual failure of previous art historical attempts to distinguish Byzantine, Western, and Islamic visual cultures of the early Middle Ages, attempts that "often fall back on ethnic, racial, or religious essentialisms that no longer convince" (148). Anderson, I think rightly, sees Cosmos and Community in Early Medieval Art as an effort to produce one possible basis for a new narrative of early medieval art, but he recognizes that "to banish" previous narratives will take many studies along the lines of his, not just one.


The basis for a design of a high-resolution PET imaging system, utilising a wavelength-shifting (WLS) fibre readout technique is presented here. Scintillation light is transported from the individual LSO pixels in the detector array through the WLS fibres to a multi-pixel hybrid photodiode (M-HPD). Each detector array consists of a number of 2/spl times/2/spl times/10 mm LSO crystals viewed by two orthogonal ribbons of WLS fibres. An array of as many as 30/spl times/31 crystals can thus be read-out by a single, small 61-pixel M-HPD tube. The design is both compact, inexpensive and suitable for application not only in the field of small-animal PET or in a dedicated PEM system, but could also operate in a combined PET/MRI system. Initial tests have shown that the signal level generated at the detector by a single 511 keV energy-deposit, is 20-25 photoelectrons. Separate tests have indicated that, at this signal-level, a resolving time of /spl sim/25 ns could be achievable.


Abstract The micromechanisms of fracture of AZ61 + 1 wt. % Al2O3 composite in the zone of superplastic deformation was analysed and quantified in this work. The specimens were tested at temperature of 200°C at different strain rates. Changing the strain rate, from 1x10-2 s-1 to 1x10-4 s-1, a significant growth of ductility was observed. At maximum value of superplasticity the fracture was transcrystalline ductile with dimples of two size categories. Based on the statistical analysis of fracture micromechanisms at the elevated temperature and strain rates of 10-0- 1x10-4 s-1 hyperbolic dependency was depicted according to Gurland - Plateau theory.


The impact of financial crisis has not been uniform across the globe. Apart from the epicentre of the crisis, those with higher dependency on external markets both for trade and finance had more immediate and larger impact of the global contagion. In contrast, the small businesses with lower diversification of product base and little option for downsizing had a relatively homogeneous impact across the world economies irrespective of trade dependency of the economy. This is because of strong backward linkages or an extensive participation of small and medium industries in the upstream supply chain, producing intermediates for both the exporting as well as non-exporting large industries. On the other hand, credit crunch faced by the small and medium enterprises (SMEs), deemed less credible but relatively more credit dependent than large industries, invigorated the impact of the crisis. Besides, some factors very specific to SMEs made them more vulnerable to the crisis.


The Brazilian Electric Energy Agency (Aneel) published the Normative Resolution #482/2012 in order to reduce barriers to the installation of distributed generation from renewable resources (wind, photovoltaic, hydro, biomass and cogeneration) connected at the distribution grid and to encourage the development of these technologies in Brazil. This article presents the rules of the new regulation and also presents small wind turbines as a feasible option for the Northeast Region of Brazil


The atypical work between family and social vulnerability. Some reflections to explore new empirical approach During last decades in most of the European countries some relevant changes in the labour market happened, as the increase of unemployment and flexibility of job. These events put in crisis those welfare systems like the Italian one where permanent jobs represent the main protections for workers and their families. This article put the focus on the social vulnerability concept like a frame to understand some effect of the changes inside the labour market. In particular it put the focus on the necessity to use the family like unit of analysis in order to explore the relation between work condition and family condition.


In WM, black coated tongue is associated with smok -ing, the use of medication such as antibiotics or cortico-steroids, radiotherapy, or poor oral hygiene. It is consid-ered a benign change resulting from decreased apoptosis of the epithelium on the dorsum of the tongue, with consequent elongation of the papillae and modification of the local flora, with an increase of fungi and chromo-genic bacteria.


The aim of this study is to know the influence of Total Physical Response toward student's listening skill. The writer conducted this study in Sabilillah Elementary school. The sample of this study were two classes; mathematics as the control group and  science class as the experimental group. Both pre-test and post-test were conducted to both groups. The experimental group was taught by using TPR, while the control group was taught using conventional methods. The score from both tests were then tested statictically using Mann Whitney U-Test to find out if the hypothesis is rejected or accepted. The study showed that there is a significant difference in student's listening skill between students who were taught by using TPR and who were not taught by using TPR indicated by the significant value of Mann Whitney U-Test (the result is 0.02) and the value is lower than 0.05. Thus, the Null hypothesis (H0) is rejected and the Alternate hypothesis (H1) is accepted. In this research, it is concluded that TPR has significantly influenced the listening skills of students that they were more active and relaxed during the class.


Objective To investigate effects of gabapentin(GBP) and minocycline(MINO) on expression of N-methyl-D-aspartate(NMDA) receptor subunit 1(NMDAR1) in hippocampus of status epilepticus(SE) rats induced by pentylenetetrazol(PTZ). Methods Eighty-four SD rats were randomly divided into 7 groups(12 each group): control group,PTZ group,GBP group(600 mg·kg-1·d-1),GBP treatment group(600 mg·kg-1·d-1) and 3 MINO treatment groups(45 mg·kg-1·d-1,90 mg·kg-1·d-1,180 mg·kg-1·d-1).SE model was induced by PTZ in rats.PTZ(60 mg·kg-1·d-1) was injected into the abdominal cavity of rats in PTZ and treatment groups for 3 days. GBP was given to GBP group and saline was given to control group.Epileptic discharge was observed in rat electroencephalogram(EEG) by needle electrodes with unipolar leads in the scalp.The expression of NMDAR1 was detected by immunohistochemistry. Results The expression level of NMDAR1 in PTZ group was significantly higher than that in control group(P0.01),while no significant difference between GBP group and control group(P0.05).The expression level of NMDAR1 in GBP treatment group was significantly lo-wer than that in PTZ group(P0.05),while no significant difference was found in 3 MINO treatment groups and in PTZ group(Pa0.05). Conclusions PTZ increases the expression of NMDAR1 in hippocampus neurons of SE rats.GBP can decrease the expression of NMDAR1 in hippocampus neurons of SE rats,while MINO(45-180 mg·kg-1·d-1) can′t decrease the expression of NMDAR1 in SE rats induced by PTZ.


Scirpus littoralis Schrab and Typha orientalis C. Presl are cultivated in the paddy field and in the shrimp pond in the Mekong Delta of Viet Nam for human food and providing habitat for shrimp, respectively. They are recognized as phytor emediator in brackish shrimp aquaculture wastewater treatment system. However, information o n effects of NaCl on plant growth and mineral concentrations of the two species is limite d. Therefore, the present study was carried out to identify salt-tolerance between the two species. Six NaCl salinity concentrations (0, 5, 10, 15, 20, 30 ‰) and two plant species were arranged in a completely randomized factorial design with three replications. The plants were supplied full s trength Hoagland's solution as growth condition with an increment of NaCl 5 ‰ weekly for 6 weeks. T. orientalis had 65 % mortality at the high NaCl level of 20-30 ‰ while 100 % S. littoralis plant survived with only young shoots remained green. Fresh weight of T. orientalis at the 0 ‰ was 30.6 g FW/plant higher than those at the 20-30 ‰ (8.3-6.4 g FW/plant, respectiv ly) leading to the same pattern in dry weight. The amount of Na + accumulated in the shoots of T. orientalis at 30 ‰ (27.4 mg/g) higher than those at 0-5 ‰ (2.76-10.1 mg Na /g). S. littoralis had a lower Na + content in the shoots (20.1 mg Na /g) than that of T. orientalis at 30 ‰. The Cl concentration in the shoots of T. orientalis at 0 ‰ (19.7 mg Cl /g) was significantly lower than that at 30 ‰ (83.3 mg Cl/g) and was ~1.3 times higher than that of S. littoralis at 15-30 ‰. Between two studied plants, T. orientalis accumulated a higher Na + nd Cl concentration in the roots and shoots especially at the high levels of NaCl of 15-30 ‰. That indicated S. littoralis are able to withstand salt stress and can be considered the best bio-filter candidate in the integration of constructed wetlands and marine shrimp culture towards sustainable aquacultu re in the Mekong delta, Viet Nam.


The numerous approaches for the catalytic synthesis of alkyl alcohols using an intermediate hydroformylation step are reviewed. One main strategy is a sequence where hydroformylation and hydrogenation are carried out step by step. More challenging are hydroformylation reactions under reducing conditions. In this regard, the transformation can be assisted by two different catalysts or one single catalyst (tandem reaction). A particular challenge in this respect is the undesired olefin hydrogenation. Sequences where hydroformylation is combined with a subsequent aldol reaction are of huge economic importance. The different performances of the catalytic systems on the basis of rhodium, cobalt, palladium, and ruthenium are described together with typical organic ligands, reaction conditions, and selected applications.


64 Background: Locoregional recurrence (LR) remains a major source of morbidity and mortality in breast cancer. Our primary aim was to evaluate the impact of endocrine therapy (ET) on time to LR.

METHODS
A retrospective chart review of breast cancer patients (pts) treated with lumpectomy and locoregional radiation from 1999-2005 at the Princess Margaret Cancer Centre was carried out. LR was defined as ipsilateral breast or lymph node recurrence. Kaplan-Meier estimates of survival and univariate analyses were performed for age, menopausal status, tumor and nodal stage, grade, receptor status, adjuvant chemotherapy (AC) and ET.

RESULTS
Of 440 pts evaluated, the mean age at primary resection was 56 years (yrs) (range 40-79), and 67% were postmenopausal. The majority had ductal carcinomas (87%) and grade 1-2 (68%) tumors. Tumor distribution was 315 (72%) T1, 120 (27%) T2, 4 (1%) T3; 138 (31%) were node positive. Receptor status was ER/PR+HER2- 206 (47%), ER+PR+HER2unknown 80 (18%), ER-PR-HER2unknown 41 (9%), and triple negative 37 (8%). AC was used in 190 (43%). ET (tamoxifen and/or aromatase inhibitors) was initiated in 294 (84%) eligible pts, and 267/294 (91%) completed a minimum duration of ≥2 yrs. Overall, LR occurred in 24 (5%) pts, and 8/24 (33%) pts with LR also had distant metastases. Average time from surgery to LR was 5.4 yrs (range 8 months-12 yrs). The average duration of ET in pts with LR was 4.3 yrs (range 0-8), and 5.8 yrs (range 0-12) without LR. Of ER/PR+ pts with LR, 3/15 (20%) did not receive ET. At the time of LR, 5 (33%) pts were receiving ET. After stopping ET, 2 (13%) recurred 0-2 yrs, 3 (20%) at 4-5 yrs, and 2 (13%) at 7-8 yrs. Treatment with at least 2 yrs of ET predicted for fewer recurrences: at 2 yrs LR-free rate was 100% vs 90% for <2 yrs ET; at 5 yrs 99.6% vs 84%; and at 8 yrs 98.2% vs 84% (p=0.0092). ER/PR+HER2- pts had lower LR risk (p=0.028), and ER-/PR-/HER+ had higher LR risk (p=0.029). The remaining variables were not associated with risk of LRs. Survival post-LR was 90% (95%CI 64-97%) at 2 yrs and 65% (95%CI 34-84%) at 5 yrs.

CONCLUSIONS
Pts who completed at least 2 yrs of ET had significantly lower risk of LR. The average time to LR was 5.4 years, and pts with LR had decreased survival at 5 yrs post-recurrence.


It is well known that the components of microcapsule prepolymers have great influence on the structures and morphologies of the resultant self-healing microcapsules. The synthesis of high-performance self-healing microcapsules is benefited to the presence of high-content multimethylol urea in the reaction system. In this contribution, the components of microcapsule prepolymers prepared under different reaction conditions, including temperatures, pH values and mole ratio of formaldehyde to urea, were studied and quantificationally analyzed using polarized microscopic melting point meter, infrared spectroscopy and 1 H NMR spectroscopy. It was found that increasing the temperature and pH value in the reaction system could significantly promote the secondary reaction respectively, resulting in the decreased yield of dimethylol urea in the reaction system. When increasing the mole ratio of formaldehyde to urea, the yield of dimethylol urea in the reaction system increased, and the yield of trimethylol urea decreased simultaneously. Furthermore, the temperature of the reaction system during the heating process was monitored, and it indicated that the temperature changed at a constant path when a fixed heating rate was performed.


Professor Ralf Gold and his team1 report on a cohort of 15 patients with natalizumab-associated progressive multifocal leucoencephalopathy (PML) who were treated at the university hospital of Bochum, Germany. This is the largest PML series from a single institution reported so far. It comprises almost 5% of the total PML cases presently known worldwide. The most remarkable observation is that none of the patients died during 21.5 months of median follow-up. By contrast, the overall lethality of natalizumab-associated PML is currently about 20%. What can we learn from these findings?


The radiation pattern at 1775 megahertz of a F-102 airplane with four cavity backed slot antennas at given locations measured by U.S.A.F. RAT-SCAT, New Mexico, is compared with its ultrasonically simulated radiation pattern taken at the Radar Simulation facility of the Wave Propagation Laboratory, University of Houston, using a 22.6 to 1.0 scaled down model, at 0.2 megahertz utilizing spherical transducers to simulate isotropic antennas. The exact simulation of horizontally polarized electromagnetic waves in air by longitudinal ultrasonic waves in water was further supplemented by a reasonable match of the Fresnel reflection coefficient by the aircraft fuselage material in both cases. The comparison shows that overall radiation patterns are indeed well simulated, as to their general variation around their isotropic level, including the location of major maxima and minima. Furthermore, there are no nulls deeper than 10 db and wider than 3\deg-5\deg at their +3 db points in both patterns. This comparison verifies the utility of ultrasonic simulation of electromagnetic radiation of antennas mounted on complex aerodynamic bodies. It is believed to be the first time that antenna radiation has been successfully ultrasonically simulated for a flat ground plane as well as a large aerodynamic Ground plane such as the F 102.


Mycoplasmal pneumoniae is the main respiratory disease in swine. The most efficient way to control it is through the use of vaccines (bacterins), whose production cost is high. The objective of this work was to develop a new alternative for controlling Swine Mycoplasmal Pneumoniae, based on a recombinant subunit vaccine containing the R1 region of P97 adhesin of Mycoplasma hyopneumoniae fused to the B subunit of the heat-labile enterotoxin of Escherichia coli (rLTB-R1). In this work we report the amplification of the genes, genetic fusion between LTB and R1 coding sequences, cloning, construction of the expression vector, as well as expression and purification of rLTB-R1 in E. coli.

Niat whistleblowing berpengaruh signifikan terhadap kapabilitas pencegahan fraud.


The authors propose a simple cell scheduler for input queueing ATM switches. The proposed self-firing cell scheduler consists of N/sup 2/ processing elements connected by a two dimensional torus network, where each processing element can determine the diagonal by itself in a distributed manner. It allows a simple implementation for high speed ATM switches.


OBJECTIVES
Emergency department (ED) crowding poses a severe public health threat, and identifying acceptable means of treating medical conditions in alternative sites of care is imperative. We compared patients' experiences with in-home urgent care via mobile integrated health (MIH) vs urgent care provided in EDs.

STUDY DESIGN
Survey, completed on paper, online, or by telephone. We surveyed all patients who received MIH care for an urgent health problem (n = 443) and consecutive patients who visited EDs for urgent care (n = 1436).

METHODS
Study participants were members of a managed care plan who were dually eligible for Medicare and Medicaid, 21 years or older, and treated either by MIH or in an ED for nonemergent conditions around Boston, Massachusetts, between February 2017 and June 2018. The survey assessed patients' perceptions of their urgent care experiences.

RESULTS
A total of 206 patients treated by community paramedics and 718 patients treated in EDs completed surveys (estimated 66% and 62% response rates, respectively). Patients treated by MIH perceived higher-quality care, more frequently reporting "excellent" (54.7%) or "very good" (32.4%) care compared with ED patients (40.7% and 24.3%, respectively; P < .0001), and were significantly more likely to report that decisions made about their care were "definitely right" compared with patients treated in the ED (66.1% vs 55.6%; P = .02).

CONCLUSIONS
Patients appear satisfied with receiving paramedic-delivered urgent care in their homes rather than EDs, perceiving higher-quality care. This suggests that in-home urgent care via MIH may be acceptable for patients with nonemergent conditions.


Photolysis of methyl 2-benzoyl-1,4-dihydro-1,4-ethenonaphthalene-3-carboxylate (4) produces two di-π-methane photoproducts in solution, but three different products in the solid state. The structures of (4) and an unusual solid-state photoproduct methyl 6c-benzoyl-2a,2b,6b,6c-tetrahydrobenzo[a]cyclopropa[cd]pentalene-6b-carboxylate (13) have been determined by X-ray crystal analyses


Leakage current is a critical issue in transformerless PV systems, which creates safety and EMI problems. The traditional full-bridge inverter using unipolar sinusoidal pulse-width modulation suffers from high-frequency leakage currents. To solve the problem, this paper proposes a singlephase inverter for transformerless PV generation systems. The proposed topology significantly reduces the leakage current by AC-decoupling and common-mode voltage clamping. Additionally, high efficiency is achieved because of the low conducting losses compared with conventional transformerless topologies. Also, the proposed topology is symmetrical and power device losses are reasonably balanced, for good thermal design and prolonged inverter life time. The common-mode performance of the proposed topology is verified by simulation and experimentally with a 2kW system.


The depletion of trichloroethene (TCE) was studied in microcosms containing water and three types of natural sediment ranging in composition from highly organic to a calcareous sedimentary rock. The depletion rates varied slightly in the different sediments. The first-order rate constant k/sub 1/ for the depletion of TCE ranged from 8.7 x 10/sup -4/ and 4.9 x 10/sup -4/ h/sup -1/ in soils contaminated with TCE prior to microcosm preparation to 3.4 x 10/sup -4/ and 4.6 x 10/sup -4/ h/sup -1/ for soils with a large organic content to 3.2 x 10/sup -4/ h/sup -1/ for crushed rock microcosms. Depletion was found to follow nonlinear forms of Michaelis-Menten kinetics in the organic sediments; however, microcosms containing crushed rock and water followed a linear form of the equation. K/sub m/ values were found to be dependent on the percent of total organic carbon in the sediment. 16 references, 4 figures, 2 tables.


This chapter examines the role of images in the Roman domestic sphere, focusing on the contribution of paintings, mosaics, and other forms of representation to the construction of the Roman house as a place of self-representation and social interaction. Images were essential to the purposes of both shaping the environmental quality of domestic spaces and informing visitors about their character, function, and the behavior that was required from them. The case study of an apparently minor genre of Roman wall painting, that of still-life pictures (i.e., images of food and silverware), allows in-depth discussion of how the choice and understanding of subject matters depended on and relied upon shared mechanisms of recognition, as well as a tight semantics of meanings, values, and habits.

Sociology, political science, and economics have undergone parallel revolutions since the late 1970s, following on the heels of the behavioral revolution of the 1950s and 1960s. Four distinct institutional paradigms have emerged: sociological institutionalism, rational choice institutionalism in political science, historical institutionalism in the same discipline, and new institutional economics. Sociologists argue that economic institutions—which encompass paradigms, conventions, rules, and regulations—shape modern behavior. National institutional differences produce stable patterns of economic behavior within countries, but institutions themselves change over time. Four recent trends in sociology are reviewed: studies of the global spread of regulatory institutions; studies of the use of economic theories to support policy design and economic conventions; studies of market actors as social movements promoting economic change; and studies of the moral and cultural underpinnings of the economy.

This article, based on an ethnographic study of a biology laboratory in Bordeaux, considers the role of the image in the experimental sciences. It describes the process of producing a "beautiful image" destined for a scientific article and necessary for its submission for publication. Over the course of the description of the material issues behind the production of the "beautiful image," it appears as proof of biologists' experimental practices and scientific virtues.


The mechanism of redistribution of trichloromethyl and chlorotrimethyl silane catalyzed by ZnCl2 has been obtained by calculation.The curves of IRC pathways and the imaginary vibration modes of transition states are also obtained.The catalytic activity of ZnCl2 is lower than that of AlCl3,which is accord with the result of the experiments.


Purpose: Current RTOG protocols allowing IMRT delivery for prostate cancer limit the hot spot such that 5mm and >3 mm for 19 and 103 seconds per average treatment (8–17 minutes), respectively. Conclusions: Hot spot generation appears to be a complex function of PTV volume, the number of beam directions and subsequent overlap, and the penalties applied to nearby critical structures during optimization. PTV volume alone contributes minimally for the range of volumes in this study. It is possible to deliver a more efficient and homogeneous plan through localization and PTV reduction and/or active tracking since the prostate migrates out of the volumes studied with minimal frequency.


This article focuses on the master surgical scheduling (MSS) problem. In order to make an effective coordination between case mix planning problem (CMPP), a strategic level problem, and MSS, the results obtained from solving the CMPP is used as an input for the respective MSS. The MSS states which patient types receive surgery on which day. In this study, a mix integer linear programming model is developed to construct an MSS. The proposed model is based on a lexicographic goal programming approach. The aim of the developed model is minimizing the OR spare time while considering the results of the CMPP. In this paper, data required to solve MSS, is collected from a medium-sized Iranian hospital. The results show that the performance of the proposed method is better than the solution put in practice in the hospital.


Social media promote the boundary-less organization and enable networking, but challenge organisations in that they are expected to do so on a much larger scale. These expectations affect the entire society and thus demand a reflection of one's own position to successfully manage the change. The library as the traditional keeper of the knowledge hoard is confronted with new, globally operating actors and changed user habits of the library's stakeholders. This paper reflects the roles of the library in the context of the university from the perspectives of knowledge work, knowledge development and social media. The paper discusses the status quo with the knowledge maturing model and presents approaches for adapting library offerings according to the three design dimensions content, process and service.


The energy conversion conjugate conduction-convection Ohmic mixed heat and mass transfer of an incompressible viscoelastic fluid on thermal forming stretching sheet has been studied. The present study has been applied similarity transformation method to change the partial differential equations transform to a set of nonlinear ordinary differential equations, and it has also been used an implicit finite-difference method to solve the system's equations. The numerical calculating results for the conjugate heat transfer energy conversion problem which have been carried out as functions of viscoelastic number E, Prandtl number Pr and buoyancy parameter Gr, Gc, etc. The parameters of E, E1, Gr, Gc and Pr are important energy conversion factors in this study, it should be produced greater heat transfer energy conversion effect with a larger values of E, E1, Gr, Gc or Pr, but the parameter M or Ec will be reduced the heat transfer energy conversion effect. For mass transfer energy conversion processing, the Schemidt number Sc or reaction parameter Rc will be increased the mass transfer energy conversion effects. For heat conduction energy conversion aspect, the convection-conduction number Ncc will be increased the heat conduction energy conversion effect. Because of present study has been studied about many parameters physical features, so that it is also belong to a multimedia physical feature study work.

Measurements of spatial and temporal variation of spectra in the wavelength range from vacuum ultraviolet (VUV) to soft x-ray (SX) are necessary to determine radiation power losses and ion density profiles which directly relate to the impurity transport, confinement and sources in magnetically confined plasmas. We developed space- and time-resolving VUV (150-1050 A) [1] and SX (20-350 A) [2] spectrographs and applied for impurity diagnostics in the tandem mirror GAMMA 10 [3]. For quantitative analyses of emission lines, it is important to characterize the absolute sensitivity of these spectrograph systems throughout their wavelength ranges. Previously, we measured the absolute sensitivities of VUV spectrograph by changing the incident light angle of the VUV spectrograph. We have changed the recording camera for improving the sensitivity of the VUVspectrograph. In this report, we show the absolute sensitivity of the VUV spectrograph with using a new CCD camera.

An evaporation model based on kinetic theory is developed to analyze the depletion of polydisperse perfluoropolyether lubricants caused by the rapid laser heating in a heat-assisted magnetic recording (HAMR) system. The simulation studies show that the distributions of molecular weights in a polymer, which are usually characterized by the polydispersity index (PDI), have significant effects on the lubricant depletion. As PDI increases, the lubricant loss at the beginning of laser heating becomes more severe due to preferential evaporation of lighter molecular weight components in the mixture. Therefore, lubricants with high molecular weights and low PDIs should be more favorable in HAMR application.


We solved multiobject nonconvex programming by means of homotopy-interior method and got the minimum weak effect solution under quasi-normal cone condition;meanwhile we proved the convergence of this method.

Several aspects of core-level photoelectron em1sswn from solid surfaces as excited by high-brightness variable-polarization synchrotron radiation have been studied with a new beamline and experimental station at the Advanced Light Source in Berkeley. These include: resolution of different chemical states and site types via high-resolution photoelectron spectroscopy (PS), the use of state-resolved photoelectron diffraction (PD) . to determine local atomic geometries, and the observation and analysis of circular dichroism (CD) effects in photoelectron diffraction. These methods have been applied to clean and oxygen-exposed surfaces ofW(llO). Full-solid-angle photoelectron diffraction from clean W(llO) was measured, with the surface and bulk atoms being clearly resolved. This provided a test case for R-factor structure analysis of low energy photoelectron diffraction data, with experiment compared to theoretical calculations based on multiple-scattering theory. We found a 4.5% outward relaxation of the surface W layer, in good agreement with prior measurements. We also determined the positions. of o~ygen atoms in a saturated (lxl) oxygen overlayer on W(llO) from full-solid-angle photoelectron diffraction with chemical state resolution, arriving at an W -oxygen interplaner distance of 0.91 ± 0.05 A and a small shift from the geometric center of the pseudo-threefold hollow sites on W(llO) by O.IOA in the (1 TO] direction. Using timeand state-resolved measurements, we studied the adsorption kinetics of oxygen on W(ll 0), finding that gas pressure is an important variable in the kind of adsorption structure formed, with low-pressure adsorption in the 1 o-9 torr range not leading to any


It is a pleasure and honor to be with you on this important occasion. I am not unmindful of the fact that we are speaking about Jewish Studies in Berlin at this Academy and in this building. I am therefore grateful to all those who have made our conversation possible. As my title indicates, I shall attempt to speak to the issue of context in our field, and its role in shaping our scholarly discipline and pedagogical task. It goes without saying, that each university must work out its own intellectual agenda in light of received traditions, present realities, and collective visions of its future purposes. The correlation of these forces is part of the contested space of the academy; and we all know that this contestation is not only shaped by intellectual forces. Indeed, political and pedagogical interests form and re-form in ever new coalitions. One can hardly ignore these factors. Nevertheless, when it is given to us to rethink the task of our universities, and the place of certain fields of study within them, we must try I believe to transcend the merely expeditious and timely solutions, and exercise the most farsighted thoughtfulness.


This paper analyzes the effect of the gender of local policymakers on policy outcomes. Analyzing a rich dataset from Brazilian municipalities and using a regression discontinuity design, we find that municipalities ruled by female mayors have better health outcomes, receive more federal discretionary transfers, and have lower corruption. Additionally, male mayors hire more temporary public employees than their female counterparts when they are allowed to run for re-election, and when municipal elections are approaching. These findings suggest that male mayors may promote more political patronage than female mayors and that men and women may respond differently to local election incentives. ∗Fernanda Brollo, firstname.lastname@example.com, Ugo Troiano, email@example.com.

We have conducted modeling studies of several gas cell shots on the Z accelerator at Sandia National Laboratories in order to study the effects of the irradiance of a low-density gas by a strong x-ray source. Thus far, we have successfully matched a synthesized neon absorption spectrum to an experimental spectrum obtained from one of the shots, with especially good agreement for many of the He-like neon absorption lines. We have also conducted a study scaling the density of the Ne in the gas cell, and have concluded that the minimum density for which there are still measurable spectral features is on the order of ∼ 7.5 × 10 cm, which implies an ionization parameter of ∼ 70 erg cm s. Lastly, we have synthesized new spectral diagnostics for future experiments in the form of time-resolved absorption and emission spectra, and predict that future experiments using such diagnostics will show the weakening of Li-like lines in both absorption and emission and the strengthening of the Lyman alpha line in emission as time progresses. These results have demonstrated we can successfully model the photoionization experiments being conducted at Sandia, and that our modeling procedure can be implemented to design new experiments for future shots at Sandia. Our analysis of the excitation/ionization kinematics and physical conditions of the photoionized plasma has also helped benchmark the atomic kinetics models for these plasmas, which should lead to better interpretation of measured spectra from plasmas photoionized by cosmic sources.


The ability of seed extracts of Trigonella foenum-graecum (T. foenum-graecum) and Cuminum cyminum (C. cyminum) to act as natural coagulants was tested using natural turbid water. Seed extracts were prepared using distilled water and NaCl (0.5 M and 1.0 M) solution. Only 1.0 M NaCl extract of T. foenum-graecum had coagulation capability and did not depend on pH values. Further it showed that natural coagulant obtained from T. foenum-graecum is temperature (upto 100?C) and pH stable (pH 4.0 - 10.0). Extract of C. cyminum had very minimal (16 ± 2) coagulation property. The seed extract of T. foenum-graecum showed about 80% coagulation properties, where as the best known natural coagulants such as Strychnos potatorum and Moringa oleifera, and chemical coagulant such as Al2(SO4)3 showed around 90%, 65% and 95% respectively, which are used as standards for the present study. When compared with pond water, T. foenum-graecum extract treated water shows decrease in alkalinity, turbidity, KMnO4 demand and total coli-form. This study reveals that seed extract of T. foenum-graecum can be used as natural water coagulant.

This chapter introduces the "Sweet Thing" scheme through postwar popular music, and defines a scheme as a shared musical structure with predetermined constraints and allowances. The "Sweet Thing" scheme is the result of the intertwining of various musical components of many different sources, some with very deep roots in the past, which penetrated many genres of American vernacular music. With the advent of radio and the phonograph in the early twentieth century—and especially with the widespread circulation of blues, country, and gospel records—the various components of these older forms grouped together and intertwined in different ways, resulting in a number of hybrids and variants. It is this cluster of twentieth-century variants that I call the "Sweet Thing" scheme. Defining its musical characteristics in a way flexible enough to accommodate its substantial variation and exploring the historical sources for its musical attributes are the subjects of this book.


Vertical federated learning is a collaborative machine learning framework to train deep leaning models on vertically partitioned data with privacy-preservation. It attracts much attention both from academia and industry. Unfortunately, applying most existing vertical federated learning methods in real-world applications still faces two daunting challenges. First, most existing vertical federated learning methods have a strong assumption that at least one party holds the complete set of labels of all data samples, while this assumption is not satisfied in many practical scenarios, where labels are horizontally partitioned and the parties only hold partial labels. Existing vertical federated learning methods can only utilize partial labels, which may lead to inadequate model update in end-to-end backpropagation. Second, computational and communication resources vary in parties. Some parties with limited computational and communication resources will become the stragglers and slow down the convergence of training. Such straggler problem will be exaggerated in the scenarios of horizontally partitioned labels in vertical federated learning. To address these challenges, we propose a novel vertical federated learning framework named Cascade Vertical Federated Learning (CVFL) to fully utilize all horizontally partitioned labels to train neural networks with privacy-preservation. To mitigate the straggler problem, we design a novel optimization objective which can increase straggler's contribution to the trained models. We conduct a series of qualitative experiments to rigorously verify the effectiveness of CVFL. It is demonstrated that CVFL can achieve comparable performance (e.g., accuracy for classification tasks) with centralized training. The new optimization objective can further mitigate the straggler problem comparing with only using the asynchronous aggregation mechanism during training.


developed, large segments of the Muslim population do not have access to adequate banking services—often because devout Muslims are unwilling to put their savings into a traditional financial system that runs counter to their religious principles (see box). Islamic banks seek to provide financial services in a way that is compatible with Islamic teaching, and if Islamic banks can tap that potential Muslim clientele, that could hasten economic development in these countries. there is evidence of close correlation between financial sector development and growth. Countries whose financial systems offer a variety of services—including banking and insurance— tend to grow faster. Banks, whether Islamic or traditional, play a fundamental economic role as financial intermediaries and as facilitators of payments (King and Levine, 1993). they also help stimulate saving and allocate resources efficiently. Globally, the assets of Islamic banks have been expanding at double-digit rates for a decade, and Islamic banking is an increasingly visible alternative to conventional banks in Islamic countries and countries with many Muslims. our study identifies the sources of Islamic banking's expansion and ways to stimulate its continued growth. Knowing what drives the development of Islamic banking will help developing countries in Africa, Asia, and the Middle East catch up.


: Based on wheel-rail vertical dynamics, wheel-rail rolling contact theory and abrasion theory of materials, a calculation model of high speed railway rail corrugation is established and the corresponding numerical method is developed. The wheel-rail vertical dynamic model is established using the parameters of a corrugated ballastless high-speed railway. Hertz contact theory and Carter two-dimensional theoretical model of wheel-rail contact are used to calculate the wheel-rail contact force in normal and tangential directions. The wear of rail surface is determined using friction work. The development of the high-speed rail corrugation is reproduced numerically. The influence of some key parameters of high-speed vehicle and track, such as vehicle primary vertical suspension stiffness and damping, rail fastener stiffness, fastener damping and rail hardness, on the rail corrugation of high-speed railway. The results indicate that some range of the key parameters of high-speed vehicle and track will help to alleviate the development of corrugation on the high-speed railways.


The production of nuclear energy will result in high-level radioactive waste (HLRW), which brings potential environmental dangers. Selecting a proper disposal repository is a crucial step in the development of nuclear energy. This paper introduces firstly the hydrogeological conditions of the Beishan area in China. Next, a regional groundwater model is constructed using a multiphase flow simulator to analyze the groundwater flow pattern in the Beishan area. Model calibration shows that the simulated and observed hydraulic heads match well, and the simulated regional groundwater flow pattern is similar to the surface flow pattern from the channel network, indicating that the groundwater flow is mainly dependent on the topography. In addition, the simulated groundwater storage over the period from 2003 to 2014 is similar to the trend derived from the Gravity Recovery and Climate Experiment satellite-derived results. Last, the established model is used to evaluate the influences of the extreme climate and regional faults on the groundwater flow pattern. It shows that they do not have a significant influence on the regional groundwater flow patterns. This study will provide a preliminary reference for the regional groundwater flow assessment in the site of the HLRW in China.


Transmitting entity for different subbands to use different steering vectors to obtain a diversity oriented. Each steering vector is associated with the sub-defined or configured beam. Any steering vector may be used to guide diversity. Steering vectors may be defined such that the subband beam in a continuous change rather than a mutation. This can be applied in each of the plurality of sub-band transmit antennas continuously varying phase shift is achieved. As an example, the phase shift may vary in a linear manner to bring each of a plurality of emission antennas, and each antenna may be associated with a different phase slope. Or by delaying the corresponding time-domain cyclic shift samples, to achieve the application of linearly changing phase shifts to modulation symbols in the frequency domain.


Student completion rates in higher education are currently a hotly debated topic. The so called 'unk rates' have become a key performance indicator of higher and further education, with universities and colleges now publicly 'named and shamed' by media reporting of league tables of completion and drop-out rates. Student completion and drop-out rates are thus an increasing cause for concern for many universities (Johnes and Taylor 1989). The concern surrounding low (and declining) student retention rates in UK higher and further education has stimulated a ood of recent research seeking to examine its causes and consequences (Audit Commission 1993; Martinez 1997). A number of signiŽcant factors have emerged in the explanation of student turnover including: academic and quality issues, Žnancial difŽculties, accommodation problems, and a range of personal factors such as personality, level of commitment to higher education, the problems of personal adjustment and student academic ability (see Tinto 1987). A wide range of theoretical frameworks to aid understanding (Mackie 1998) and 'solutions' (Noel 1997; Rickson and Rutherford 1995) to the problem of student retention have been put forward. However, this burgeoning research output has largely concentrated on full-time undergraduates and the problem of part-time student drop-out from higher education has been rather neglected. Here different sets of factors are likely to inuence student drop-out and persistence. Frequently a new stakeholder – the employer – is interested and may signiŽcantly inuence the outcome. In particular an ignored aspect of this debate – and the concern of this paper – is the impact of formal training agreements between the employer and the employee. Training agreements are legal devices that establish the conditions under which an employer is prepared to fund the training of an employee. They typically impose a financial penalty on the voluntary termination of a trainee's

By introducing the flexible bis-pyrazine–bis-amide ligands into a polyoxometalates (POMs) system, five POM-based metal–organic complexes, {Cu3(L1)2[CrMo6(OH)6O18]2(H2O)2}·10H2O (1), [CuL1(Mo8O26)0.5]·H2O (2), [Cu2(L1)2(HPMoVI10MoV2O40) (H2O)2]·2H2O (3), [Cu2(L1)2(SiMo12O40) (H2O)2]·2H2O (4), [Cu2(L2)2(SiMo12O40)]·2H2O (5) [L1 = N,N′-bis(2-pyrazinecarboxamide)-1,3-propane, L2 = N,N′-bis(2-pyrizinecarboxamide)-1,6-hexane], were synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, powder X-ray diffraction (PXRD) and thermal gravimetric analyses (TG). Single-crystal X-ray analysis reveals that compound 1 is a 1D infinite ribbon-like chain with Anderson type polyanions [CrMo6(OH)6O18]3− as building blocks. Compound 2 is a 2D layer constructed from 1D helical [Cu-L1]n2n+ chains and [Mo8O26]4− anions, in which the octamolybdates also act as inorganic building blocks. Compounds 3 and 4 are isostructural, and display 2D supramolecular networks based on the 1D [Cu-L1]n2n+ chains, in which the Keggin polyanions serve as noncoordinated templates. Compound 5 is a 3D supramolecular framework constructed from the 2D [Cu-L2]n2n+ layers and the Keggin [SiMo12O40]4− polyanion templates. In compounds 1–4, the L1 ligands display the same symmetric coordination mode with two chelating sites. When lengthening the spacer of the ligand, L2 exhibits an asymmetric coordination mode in compound 5. The structural diversities of 1–5 show that the different polyoxoanions and spacer lengths of the ligands play key roles in the construction of various architectures. The title compounds represent the first examples of introducing flexible bis-pyrazine–bis-amide ligands into the POMs system. In addition, the electrochemical properties of compounds 2–5 and the photocatalytic activities of the title compounds on the degradation of methylene blue (MB) under UV, visible light and sunlight irradiation have been investigated in detail.


We propose a content-based parallel image retrieval system to achieve high responding ability. Our system is developed on cluster architectures. It has several retrieval servers to supply the service of content based image retrieval. It adopts the Browser/Server (B S) mode. The users could visit our system though web pages. It uses the symmetrical color-spatial features (SCTSF) to represent tile content of an image. The SUSF is effective and efficient for image matching because it is independent of image distortion such as rotation and flip as well as it increases the matching accuracy. The SCSF was organized by M tree. which could speedup the searching procedure. Our experiments show that the image matching is quickly and efficiently with the use of SCSF. And with the support of several retrieval servers, the system could respond to many users at mean time.


Object movement detection during observers' self-motion is critical in navigation. Given ample optical available variables, which of them would be used would help us reveal the strategies being employed. In this work, using functional magnetic resonance imaging (fMRI) methods, we investigated the neural substrate underlying specific visual motion related tasks, such as time to passage (TTP), depth parallax, and collision. Using a visual search paradigm implemented with MATLAB, we developed a psychophysical task to investigate how the target characteristics (initial depth, initial eccentricity, and independent velocity), spatial attention, and heading estimation would affect visual search, for better understanding the mechanisms involved in object movement detection during self-motion. The fMRI analysis shows that: 1. Bilateral precentral sulcus (PreCS), postcentral sulcus (PostCS) and bilateral hMT are strongly activated during the TTP task. 2. Cortical regions along the dorsal visual processing pathway, including bilateral hMT, superior parietal gyrus (SPG), PostCS, PreCS and superior frontal gyrus (SFG), play important roles in our depth perception test. 3. In the collision test, similar activation pattern has been found in normal controls and stroke patients with visual deficits, intraparietal sulcus (IPS), SPG, supplementary area (SMA) and premotor regions are highly activated. The psychophysical results in visual search tasks indicate targets located in central visual field


ABSTRACT Teaching English to students is very effective when it is implemented intergratedly by covering the four skills of English; listening, speaking, reading, and writing. The  implementation purpose of English language teaching at Elementary School is for socializing English language, building the basic knowledge of English, motivating students in learning English for their need of the language in the future. This research is aimed to describe the implementation of English language teaching conducted by the English teachers specially about, curriculum, syllabus design, teaching materials, and teaching media. It also described teachers activities while teaching English such as, the use of teaching method, and after teaching English such as, teaching evaluation (preparing, processing, and evaluating). It also described about the teachers' problems and the teachers' strategies in solving the problems. This study employs qualitative research design with descriptive approach. The subjects of the study were three teachers who tought English in grade I-II, III-IV, and V-VI at MIN Jambo Tape Banda Aceh. The data were collected through questionnaire, observation, interview, and documentation. The collected data were analyzed by using qualitative data analysis approach. The analysis was done through data classification, data reduction, data display, and drawing conclusion. The result of this study shows that MIN Jambo Tape was ready to implement English language teaching to the students since grade one until grade six. It referred to the five catagories of; 1) the provided English teachers, 2) curriculum and syllabus design, 3) teaching material, 4) teaching method, 5) and teaching media. Moreover all English teachers (100%) at MIN Jambo Tape have made a good preparation before implementing English language teaching to their students but some of them still had problems while implementing it such as the use of teaching media (66.7%), teaching materials (33.3%), and teaching evaluation (33.3%). Meanwhile, to solve the problems all of them (100%) discussed it with the other English teachers, the headmaster, and students' parents.

Severe congenital neutropenia (SCN), often referred to as Kostmann syndrome, is a rare immune deficiency syndrome diagnosed at or soon after birth, characterized by maturation arrest of myeloid cells at the promyelocyte stage of hematopoiesis. In severe congenital neutropenia due to disorder of neutrophil production, patients are predisposed to recurrent bacterial infections. Recently, there have been reports of detected mutations in neutrophil elastase II (ELA2) gene in genomic DNA of severe congenital neutropenia. In this study we attempted to determine whether there is any mutation in elastase II gene encoding. Peripheral blood was collected from five patients with severe congenital neutropenia and 20 healthy individuals. Total RNA was isolated using RNA standard techniques from fresh separated cells by Polymorphoprep. RNA was analyzed by employing PCR amplification of reverse transcribed using a total of ten specific primers. We amplified five exons of ELA2 gene separately and sequenced each exon. Mutational analysis was performed by directed capillary sequencing method. We found mutations in all severe congenital neutropenia patients and no mutation in 20 healthy individuals. The most mutations were in exon 4 and no mutation was found in exons 3 and 5.


This chapter studies the behavior of stock returns in India. For this purpose, data from 1997 to 2010 of 14 indices traded on the National stock exchange (NSE) and Bombay stock exchange (BSE) are used and several parametric and non-parametric methods are employed to empirically test the random walk characteristics of stock returns and examine the weak form efficiency of the Indian stock market. The results from parametric tests are mixed and validity of random walk hypothesis (RWH) is suggested only for large cap and high liquid indices traded on the BSE. However, the same is not true in the case of NSE index returns. The non-parametric tests resoundingly reject the null of random walk for the chosen indices. The results broadly suggest non-random walk behavior of stock returns and invalidate the weak form efficiency in case of India. The evidence of dependence in stock returns call for appropriate regulatory and policy changes to ensure further dissemination of information and quick and correct price aggregation in the market.

The development of technology and information that is increasingly advanced at this time is still not fully understood by the community, especially among rural communities. This is indicated by the lack of community creativity in the abundance of cassava food products, where they do not realize the potential that can be created from these food products. Cassava food products are generally food products that are only processed into monotonous products such as tape, jemblem, opaque cassava, and fried cassava. So that people feel bored with the monotonous variety of processed cassava, but on the contrary if it is processed into a variety of processed cassava properly, it will have a positive impact on products that have high selling power. The expected goal of this service activity is to educate the community by making local potentials that have not been explored can be optimized, especially those that can have an impact on improving the welfare of farmers and farm workers. The implementation method is by identifying potentials and problems, planning training, socializing training, and implementing training. This activity was attended by PKK women and housewives from Sekidang Village, Sambeng District, Lamongan Regency. The results of this activity are increasing creativity and new innovations to the community, also making people aware that we can process staple foods that have high economic value and in the end can help the economy and improve the quality of life of rural communities


The ART-based neural networks summarize data into groups via the use of inner categories. A category's template elements are updated incrementally in the light of new evidence provided by the presentation of input patterns. In order to reduce approximation error, this paper proposes Bayesian Polytope ARTMAP (BPTAM) which incorporates both simplex categories and Gaussian categories. During training, the simplex categories expand only towards the input pattern without category overlap, while the Gaussian categories grow or shrink by limiting their hypervolumes. In addition, BPTAM uses Bayes' decision theory for learning and inference, which makes BPTAM robust to noise and category overlap. Based on some preliminary but illustrative experimental results, BPTAM shows better applicability to data sets with noise, statistical overlapping and irregular geometry.


This document defines a framework within which security services may be applied to MIME body parts. MIME, an acronym for "Multipurpose Internet Mail Extensions", defines the format of the contents of Internet mail messages and provides for multi-part textual and non- textual message bodies. The new content types are subtypes of multipart: signed and encrypted. Each will contain two body parts: one for the protected data and one for the control information necessary to remove the protection. The type and contents of the control information body parts are determined by the value of the protocol parameter of the enclosing multipart/signed or multipart/encrypted content type, which is required to be present.


In phosphate deprivation, the kidney is resistant to the phosphaturic effects of several well-established phosphaturic stimuli, including PTH. We examined whether a low-phosphate diet would render rats unresponsive to the phosphaturic effects of glucocorticoids in the presence and absence of PTH. Treatment with triamcinolone (1 or 50 mg/kg/day) caused phosphaturia in rats fed a low-phosphate diet and also restored rhe phosphaturic effects of PTH. Plasma phosphate was significantly increased with both doses of glucocorticoid. There were no changes in acid-base parameters with the low dose and a compensated metabolic acidosis with the high dose of glucocorticoid. Renal gluconeogenesis was stimulated at both doses and was further enhanced by PTH at the higher dose. We conclude that glucocorticoids reverse the resistance to the phosphaturic phosphate and/or enhanced renal gluconeogenesis.


Security analysis of blockchain technology is an active domain of research. There has been both cryptographic and game-theoretic security analysis of Proof-of-Work (PoW) blockchains. Prominent work includes the cryptographic security analysis under the Universal Composable framework and Game-theoretic security analysis using Rational Protocol Design. These security analysis models rely on stricter assumptions that might not hold. In this paper, we analyze the security of PoW blockchain protocols. We first show how assumptions made by previous models need not be valid in reality, which attackers can exploit to launch attacks that these models fail to capture. These include Difficulty Alternating Attack, under which forking is possible for an adversary with less than 0.5 mining power, Quick-Fork Attack, a general bound on selfish mining attack and transaction withholding attack. Following this, we argue why previous models for security analysis fail to capture these attacks and propose a more practical framework for security analysis pRPD. We then propose a framework to build PoW blockchains PRAGTHOS, which is secure from the attacks mentioned above. Finally, we argue that PoW blockchains complying with the PRAGTHOS framework are secure against a computationally bounded adversary under certain conditions on the reward scheme.


In this paper, we present a method for estimating the user states during the usage of the walker, which support the walking of the user based on the physical interaction between the user and the walker. We also propose a method for renewing these estimation parameters changed by the users and the environmental conditions. The proposed methods are experimentally implemented in RT Walker, which is passive-type intelligent walker. The experimental results illustrate that the proposed methods could estimate the user states during the usage of the walker and the parameters for estimating the user states are changed based on the several kinds of the conditions such as physical size, daily conditions and operational characteristics of the users, environmental conditions, and so on


There is a great diversity of approaches to undertaking action research. This diversity reflects the variety of intentions, theories, processes, and outcomes that action research is designed to encompass and the multiplicity of people, places, and issues involved. Such diversity has in turn been cited both as a strength of action research, this being the very diversity that supports locally focused research for practical action, and as its Achilles heel, a perceived inability to clearly articulate the quality of the research in a world that still struggles to see beyond fixed norms and standards of some other research paradigms. The issue of quality for research that is personal, political and practical is well debated in the literature (Altricher 1999; Carr 1994, 2006; Greene 2009; Kemmis 1988; Somekh 2006; Springett, Wright, and Roche 2011). The following papers offer accounts of these dilemmas being actualised in practice. They exhibit both the multiplicity of topics that concern action researchers and the kinds of questions action researchers ask about the quality of their research. The authors ask questions about the way in which action research should or could be justified, the trustworthiness of action research, how action researchers demonstrate that value and impact of their work, and for whom does, or should, it have relevance and credence. The act of 'troubling' and 'disrupting' thinking is presented, both tacitly and explicitly, as a key quality of the action research process. In 'Justifying Action Research', drawing on the Norwegian experience, Helskog discusses the need for 'taking a stand' in relation to the different but important questions of validity and justification. Starting with the approaches of Dewey (1929) and Lewin (1946), Helskog leads us through some of the epistemological grounding of action research approaches (predominantly in the western tradition) using what she terms 'a general philosophy of science perspective'. This fascinating paper argues the need for justifying the action research approach to a wider scientific population and offers insights into approaches to building a justification that values the differing epistemological underpinnings that shape action research in practice. The next paper, 'Partial and Incomplete Voices', set in the context of early childhood teachers' learning, also works with data that are deeply personal. Challenged by the politics and ethics of being an insider researcher with multiple positionings, Henderson articulates questions about doing research on/for/with people raised by working as an 'intimate insider' researcher. At the core of this paper is her struggle to find ways of reaching into meaning beyond her own, to further trouble her own discourse, and to find a way of presenting discourse that respects other ways of seeing. Working with students studying outdoor environmental education, Nicol is also concerned with disrupting the taken for granted. His methodological approach combines theories of epistemological diversity and action research, and offers both a theoretical and practical presentation of the impact of a triple-loop learning process as a means of transforming strategies for action.


Ammonia monitoring is needed in most schemes for denitrification of power plant emission. In the PALAMON system we use a 500 MHz tunable, single mode, single line, CO2 laser as light source for a low pressure, high temperature, photoacoustic cell. With this cell we can resolve the sR(5,O) line of the ammonia spectrum, and suppress the interfering C02(9R30) absorption line down to a lppm NH3 detection limit. The validity of the measured ammonia concentrations is strongly dependent on details of the sampling system and on the reliability of the calibration routines. In particular calibration with certified mixtures of NH3:N2 has proved insufficient due to the multiple and long time constants caused by adsorption of ammonia to different materials in the system. Presence of water vapor in the gas greatly reduces these time constants. Therefore a number of methods for simple production of moist calibration gases from macroscopic amounts of NH3 are applied. The calibrations are translated to response from an easily managable absorber in order to allow automated recalibration of the photoacoustic response. Data from a field test of the system, and calibration data will be presented.

The paper explores stages that teaching followed in its revolutionizing transitions from Education 1.0 to Education 4.0. The study presents a detailed analysis of the scientific approaches, which economists used in examining the influence of digital technologies on the behaviour of young people and on identifying a generation of children as "digital natives" who grew up in the era of informational changes. An assessment of traits inherent in the new generation of young people has been used as a basis for carrying out a comparative analysis of the features of "digital natives" with the distinctiveness of "digital immigrants." The study identified factors that contributed to a growing number of "digital immigrants" in developing and least developed countries. The notions of "digital cowboys" and "digital nomads" are considered in terms of their recent appearance in the academic market. Countries with the highest share of "digital natives" comprise the high-income and above-average income countries, the countries with very high levels of general Internet penetration, the countries with top ICT Development Index (IDI), and the countries with a relatively high proportion of young people. Solutions are proposed to support "digital natives" in their educational aspirations and narrow the gap between them and "digital immigrants".


With the rapid growth of multimedia applications over the wireless Internet, the demand for radio spectral resources has increased significantly. Referring to frequency spectrum allocations in Malaysia, major parts of spectrum have been assigned for government and commercial use. Despite the spectrum scarcity in meeting the demands for multimedia services, it was found from previous studies that most of the spectrum is actually not being utilised efficiently. Henceforth, lots of researches have been conducted to exploit this underutilised spectrum opportunistically without affecting the incumbents operations. Through the enabling Software Defined Radio (SDR) technology, Cognitive Radio (CR) has been proposed to solve the inefficient spectrum utilisation problems. CR is an adaptive, intelligent radio and network technology that has the ability to detect available vacant channels in radio frequency spectrum and change its particular transmission or reception parameters for efficient communication link achieved. In this thesis, SDR platform which consists of GNU Radio and Universal Software Radio Peripheral (USRP) is used for CR multimedia transmission development. In this system, adaptive Orthogonal Frequency Division Multiplexing (OFDM) is implemented to support robust multimedia transmission effectively. Next, Pseudorandom Multiband Frequency Switching is proposed for seamless frequency agility provision. For proof of concept, the proposed system is evaluated on several multimedia signals transmission. The results showed that the minimal time duration for each frequency switching of the system is approximately 1 second which resulted 20 dB for peak signal-to-noise ratio (PSNR) achievement. However, with higher rate of intermittent presence of incumbent or primary user (PU), faster switching rate is needed. Hence, the system developed needs further enhancement for a reliable and seamless multimedia transmission system to be realised.

A high-precision horizontal platform is needed for many engineering and military devices. This paper presents an automatic control device which can adjust the horizontal degree and position of the platform supported by four legs automatically. The device is controlled by PLC and positioning module, with the functions of detecting virtual legs and limit protection. The close-loop structure of control system is designed and a unidirectional control algorithm is proposed. The experiment showed that the device can adjust the level of the platform to 0.5°in 3 min1.


The study assesses how external flows influence inclusive human development in Sub-Saharan Africa. The findings reveal that remittances and FDI increase inclusive development whereas foreign aid has the opposite effect. There are three other strands of findings. First, remittances are negatively associated with: 1) middle income countries compared to low income countries where the effect is not significant; 2) French civil law countries compared to English common law countries where the effect is positive; 3) resource-rich countries compared to their resource-poor counterparts where the effect is positive. Second, foreign aid is more negatively linked to low income, French civil law, Islam-dominated, un-landlocked, resource-rich and politically-unstable countries. Third, FDI is positively associated with: 1) low income, French civil law and landlocked countries compared to respectively middle income, English common law and un-landlocked countries where the effect is insignificant; 2) politically-stable countries compared to their politically-unstable counterparts where the effect is negative.


In the operating systems of general purpose the traditional software interface for transmitting and receiving network traffic is not applicable to work with flows that have intensity order of one million packets per second or more due to the complexity of implementation and associated data structures. NetMAP interface, the addition of kernel, allows transmitting, receiving and forwarding packets at speed that is twenty times greater than the speed obtained using traditional programming interfaces for the same purpose.


We report a new thermally activated delayed fluorescence (TADF) molecule developed by the ortho-biphenyl substitution of a multi-carbazole TADF molecule. The new TADF molecule, 4mCzBN-BP, is composed of four dimethylcarbazole donors, a benzonitrile acceptor core and an ortho-biphenyl triplet scaffold. 4mCzBN-BP exhibits a bluish-green emission with a peak wavelength at 491 nm and a very high photoluminescence quantum yield (PLQY) of 95% in an mCBP host. To investigate the effect of the ortho-biphenyl substitution on the excited-state dynamics and photophysical properties of the TADF molecule, we performed time dependent density functional theory (TD-DFT) calculations of 4mCzBN-BP and two multi-carbazole TADF molecules with similar molecular structures. A local excited triplet state (3LE) with an energy (2.81 eV) close to the lowest singlet charge-transfer state (1CT) can be formed at the biphenyl of 4mCzBN-BP. However, due to the planarization of the biphenyl at the triplet state and a large steric hindrance caused by adjacent carbazole donors, 3LE at the biphenyl can only be formed by a subset of possible conformations of 4mCzBN-BP molecules in the solid mCBP host, leading to a multiexponential decay of the delayed fluorescence. Color coordinates of (0.196, 0.452), a high external quantum efficiency of 23.7% and a long operational lifetime (LT50) of 750 hours were achieved with the organic light emitting diodes based on 4mCzBN-BP.


Oral cancer is the second most common cancer in India, with squamous cell carcinoma (SCC) noted in 90% of cases. Distant metastasis (brain metastasis) from oral SCCs is rare. The incidence of intracranial metastasis is about 0.4% and 2%–8% and approximately 5% to 10% of all cancer patients develop spinal metastasis. However, vertebral metastasis is rare form of distant metastasis from SCC of the oral cavity. Multifocal metastases to the brain and spine of primary oral squamous cell carcinomas have not been reported till date which prompted us to report this case. A 35-year-old male with a history of radical resection done for SCC of the buccal mucosa followed by postoperative chemoradiotherapy presented with complaints of headache and convulsions accompanied by severe low backache and left lower limb radiculopathy with no motor or sensory deficit. Positron-emission tomography scan showed increased uptake in the left frontal lobe and in the dorsal and lumbar spine suggestive of metastasis. Magnetic resonance imaging of the brain and spine with contrast was done which showed a well-defined lesion in the left frontal lobe and contrast-enhancing lesions L5, L2, and T5 vertebra levels. Craniectomy with gross total excision of the left frontal lobe lesion was done. Histopathological examination was suggestive of metastatic SCC. The patient was advised for follow-up for spinal decompression followed by radiotherapy. We need to have a high index of suspicion for metastasis in brain and spine lesions in patients who have been diagnosed previously with oral malignancies for prompt management and better life expectancy.


Work motivation and staff positioning is one of the important issue that need to be taken into account by a management, in order to improve workplace satisfaction rating. Workplace satisfaction and employee performance begins from the appropriate work placement of individual employee, based on interest, talent and followed by motivation from management and their colleague. The purpose of this research is to analyze the influence of work place motivation and work placement to the overall satisfaction and performance of the staff in general. The research use 36 individuals as samples and all of them work inside the credit analysis at the BPD Bali (Regional development bank) of Bali, at their denpasar's branch office. The method analysis use for it is PLS (partial least square). Variable that we look upon in this research is work motivation, work placement, overall satisfaction and work performance. The final result suggest there is a strongeffect work motivation to work satisfaction. Followed by, appropriate work placement with overall employee satisfaction. Other variable work motivation has positive and significant effect towards the employee performance. Then, appropriate work placement has direct positive effect towards improvement of the work performance. And higher work satisfaction improved the work performance We recommending the company to focus upon the right work placement, because with the right work placement that take into consideration the staff interest and talent, it will create positive effect towards their satisfaction and performance. An employee will able to provide better outcome in their day to day work, if the conditions of right work placement based on talent and skill is fulfilled.


This paper presents the details of experimental study on the fracture properties of high strength geopolymer concrete. The geopolymer concrete prepared in this study was cured in ambient temperature. This was achieved by adding small amount of OPC in the mixture. A total of 42 notched beam specimens with varying span to depth ratio (l/d) between 8 and 6 and notch depth to total depth ratio (a0/d) between 0.2 and 0.4 was cast. All beam specimens were tested under three point bending test. The fracture properties, namely, fracture energy (Gf), critical stress intensity factor (KIc), process zone length (cf), and crack tip opening displacement corresponding to peak load (δc) were determined by size effect law (SEL). The results show that the fracture properties of ambient cured geopolymer concrete are comparable with that of ordinary concrete of same strength.


The incorporation of titanium oxide into the interlayers of a myristic acid exchanged lithium aluminum layered double hydroxide was done by partitioning of titanium butoxide into the interlayer, followed by hydrolysis under ambient conditions. Upon excitation with near-ultraviolet radiation in the presence of viologens and thiocyanate ion, viologen radical is formed. Cationic viologen radicals were held onto the solid surface, indicating that the titanium oxide is negatively charged. [Tetrakis(4-carboxyphenyl)porphyrinato]zinc(II) (ZnTPPC) was ion exchanged into the interlayers. Electronic spectral changes upon incorporation suggest that the ZnTPPC is in the monomeric form. In the presence of ethylenediamine tetraacetic acid (EDTA) as a sacrificial electron donor, the interlayer ZnTPPC was capable of reducing viologen molecules in solution upon visible radiation. Yields of viologen radical were higher for neutral viologens than cationic viologens, presumably due to the restricted access of cations into th...
