The authors examine the educational roles of agency personnel and faculty field instructors in the task of field work education. Particular attention is given to the rationales for the use of task supervisors, i.e., persons who do not have the MSW degree, but who have an area of specialized expertise. A number of suggestions are made concerning the range and types of field practice assignments appropriate for students concentrating in administration and planning. Suggestions are made for matching students and agency tasks and for rating student performance.


This chapter discusses the views on self-interest and morality of Richard Cumberland (1631–1718). Cumberland's view that it is a natural necessity that human beings act always to advance their own self-interest (this view being a form of psychological egoism) is explained, along with his claim that ultimate moral motivation is possible, despite the fact that agents can never do what they believe will be worse for them overall. His utilitarian natural law ethics is described. His arguments for utilitarianism—based on preservation, sanctions, human make-up, agreement, and maximization—are critically interpreted.


Satisfactory bridge management decisions should be made through balanced consideration of long-term bridge performance and life-cycle cost. The current life-cycle cost minimization criterion does not always lead to optimal maintenance management solutions that meet bridge managers' specific requirements on lifetime bridge performance under budgetary constraints. Recently bridge management planning has been conducted using combinatorial and evolutionary optimization techniques and considering simultaneously multiple objective functions. This paper summarizes new developments in multi-criteria maintenance management of deteriorating highway bridges at project-level and at network-level. Particular emphasis is placed on uncertainty propagation over the life-cyle with and without maintenance interventions. Application examples show that the multiobjective optimization methodology can produce a large pool of optimized tradeoff maintenance management solutions, which significantly facilitate decision-making by selecting a compromise solution that preferably balances different performances and life-cycle costs.

Two fungal strains of the genus Sporothrix, isolated from industrial waste water, were characterized with respect to some morphological and physiological properties. After comparison with other species of the genus Sporothrix, the fungal strains are described as Sporothrix nivea, n. sp.


The Case for a New College Governance Structure in Nevada provides a governance model that integrates higher education with economic development. Specifically the authors, in response to a call for recommendations by the Committee to Conduct an Interim Study Concerning Community Colleges (SB 391), propose a governance model that is evidence-based and constitutionally sound to achieve Nevada's economic development goals. The authors propose a separate tier of governance for twoand four-year colleges.


Abstract : This report contains a description of a computer program for estimating the parameters of a mixture of multivariate normal distributions with unknown frequencies, means, and covariances. The basic equations for the procedure are presented for the first time here, with their derivation omitted. An example with the results of the computer printout is described for an artificially constructed mixture of three bivariate normal distributions. The method of using the program and the Fortran listing are detailed in this report.

A key to my career as an archaeologist working in East Texas has been a very successful professional-avocational collaboration on a wide range of projects with individuals and avocational organizations working in East Texas, such as the Northeast Texas Archeological Society, the East Texas Archeological Society, the Valley of the Caddo Archeological Society, the East Texas Caddo Research Group, as well as the Gregg County Historical Museum, among other museums in the region that hold ancestral Caddo archaeological collections. It has been my good fortune to work with a number of very knowledgeable and hard-working East Texas avocational archaeologists and Texas Archeological Stewardship Network members over the years, including Bo Nelson (who has gone on to establish a professional career as an archaeologist and also start his own CRM firm, Tejas Archaeology, in 1997), Mark Walters, Tom Middlebrook, Patti Haskins, Robert L. Turner, Jr., Kevin Stingley, Bryan Boyd, Mike Turner, Mark Thatcher, Gary W. Cheatwood, Clyde Amick, Lee Green, and Bill Young, among others.


This research is quantitative research by using experimental method. The objective of the research is to find out whether the use of puppet as media is effective or not in improving students' vocabulary mastery for the fifth-grade students at SDN 2 Kagungan Kepil Wonosobo in the school year 2012/2013. The population of the research is the fifth grade students of SDN 2 Kagungan Kepil Wonosobo  by taking the sample from the two classes. The first class is VA which consisted of 18 students as control group. The second class is VB which consisted of 18 students as experimental group. This research used the purposive sampling. The result shows that the use of puppet as media is effective to improve students' vocabulary mastery for the fifth-grade students at SDN 2 Kagungan Kepil Wonosobo in the school year 2012/2013.. It could be proven by the computation of the t-test. The computation showed that the t-value was higher than t-table. The t-value was 8.213 while  the t-table was 2.042. It meant that 8.213 >2.042. Besides, the mean score of experimental group was raised after given the treatment from 55.33 to 73.11. Keywords: Effectiveness, Puppet Media, Vocabulary Mastery.


Finally, I would like to stress the aetiological relationship between A.P. treatment and empyema mortality. The recorded incidence of empyema in A.P. treatment is very variable, and depends partly on the differences in treatment and partly on different definitions of an ",empyema." Alexander (1937) quotes figures ranging from nil (Ulrici, 600 cases) to 21 % (Hays, 151 cases). Frostad, in Norway, has estimated it at 10%, as an average figure, and in Soderhjelm's series it was given as " only 7.5%." A consistent large series from one centre is available at Var,dasen (Rogstad, 1948). Great care is taken in the selection of cases and in the technique of closed internal pneumolysis, the director undertaking them alT himself. The empyema incidence there is only 6.4% (59 out of 918 patients). An attempt has been made to distinguish in the series between mortality due primarily to the empyema and that due to the spread of the tuberculous disease. So far as could be judged, death was due primarily to the empyema in 16 cases, or 1.7% of all those in whom an A.P. was induced. This not inconsiderable mortality is therefore due to the A.P. as a method of treatment, and should be borne in mind when the induction of a pneumothorax is being considered and weighed against the other methods of collapse of the lung. In certain cases the destruction and fibrosis of the lung indicate the need for a primary permanent method of collapse, such as that of thoracoplasty. It is certainly incorrect to induce an A.P. first in practically every case, as is sometimes done on the grounds that it is an easy and safe method of treatment and therefore should be given a trial. The misleading factor about the risk of an A.P. (empyema being only one, although perhaps the worst, of the complications) is that the risk is spread over such a long period of time that it sometimes fails to impress itself sufficiently on the mind.


Abstract In the present study, the formation of whole cellular S-nitrosylated proteins (protein-SNOs) by the reactive oxygen species (ROS), hydrogen peroxide (H2O2), and superoxide (O2•−) is demonstrated. A spectrum of protein cysteine oxidative modifications was detected upon incubation of serum-starved mouse embryonic fibroblasts with increasing concentrations of exogenous H2O2, ranging from exclusive protein-SNOs at low concentrations to a mixture of protein-SNOs and other protein oxidation at higher concentrations to exclusively non-SNO protein oxidation at the highest concentrations of the oxidant used. Furthermore, formation of protein-SNOs was also detected upon inhibition of the antioxidant protein Cu/Zn superoxide dismutase that results in an increase in intracellular concentration of O2•−. These results were further validated using the phosphatase and tensin homologue, PTEN, as a model of a protein sensitive to oxidative modifications. The formation of protein-SNOs by H2O2 and O2•− was prevented by the NO scavenger, c-PTIO, as well as the peroxinitrite decomposition catalyst, FETPPS, and correlated with the production or the consumption of nitric oxide (NO), respectively. These data suggest that the formation of protein-SNOs by H2O2 or O2•− requires the presence or the production of NO and involves the formation of the nitrosylating intermediate, peroxinitrite.


In this correspondence, we investigate in a comprehensive fashion a one-layer coding/shaping scheme resembling a perfectly cooperated multiple-access system. At the transmitter, binary data are encoded by either single-level or multilevel codes. The coded bits are first randomly interleaved and then entered into a signal mapper. At each time, the signal mapper accepts as input multiple binary digits and delivers as output an amplitude signal, where the input are first independently mapped into 2-PAM signals (possibly having different amplitudes) and then superimposed to form the output. The receiver consists of an iterative decoding/demapping algorithm with an entropy-based stopping criterion. In the special cases when all the 2-PAM signals have equal amplitudes, based on an irregular trellis, we propose an optimal soft-input-soft-output (SISO) demapping algorithm with quadratic rather than exponential complexity. In the general cases, when multilevel codes are employed, we propose power-allocation strategies to facilitate the iterative decoding/dempaping algorithm. Using the unequal power-allocations and the Gaussian-approximation-based suboptimal demapping algorithm (with linear complexity), coded modulation with high bandwidth efficiency can be implemented.


HCV antibody screening of 624,910 blood donations resulted in 3,832 samples being referred for confirmation. All were tested by RIBA‐3 with 2,710 negative, 945 indeterminate and 177 positive results. HCV RNA was detected by PCR in an average of 69.5% of RIBA‐3 positives (4 bands 84.1%; 3 bands 74.1%; 2 bands 34.1%) and only 0.53% of RIBA‐3 indeterminates. Eighty‐four percent of samples with a total RIBA‐3 band intensity score (maximum 16) of ≥8 were PCR positive compared with only 22% of those with a score of <8. Total mean band intensities for HCV genotype 1 samples (n = 65) were 13.2, genotype 2 (n = 17) 11.4 and genotype 3 (n = 65) 11.2 with type 1 samples showing greater reactivity with c100 and c33 antibodies. No PCR positive type 1 samples were found with RIBA‐3 total band scores less than 8, no PCR positive type 2 samples less than 6, whilst PCR positive type 3 samples were found with scores as low as 2. NS5 indeterminates were the most common (40.2%) single band pattern but yielded no PCR positive samples, followed by c33 (23.3%) with one PCR positive and c100 (20.2%) with one PCR positive whilst c22 indeterminates were least common (16.3%) but included three PCR positive donors. All five RIBA‐3 indeterminate PCR positive donors were type 3. © 1996 Wiley‐Liss, Inc.


OBJECTIVE
To investigate the association between multiple types of urological management and urological complications in patients with spinal cord injury (SCI).

DESIGN
A retrospective cohort study.

SETTING
Single medical center.

METHODS
Medical records of SCI patients with regular follow-up of more than two years were reviewed. Urological management was classified into five groups: indwelling urethral catheter (IUC), clean intermittent catheterization (CIC), reflex voiding, suprapubic catheter (SPC), and self-voiding. We analyzed the incidence of urinary tract infection (UTI), epididymitis, hydronephrosis, and renal stone across the different urological-management groups.

RESULTS
Of 207 individuals with SCI, the most common management type was self-voiding (n = 65, 31%) followed by CIC (n = 47, 23%). The IUC and SPC groups included more people with complete SCI than the other management groups. Compared with the IUC group, the SPC and self-voiding groups had lower risks of developing UTI (relative risk [RR] = 0.76, 95% CI, 0.59-0.97 and RR = 0.39, 95% CI, 0.28-0.55, respectively). The SPC group tended to have a lower risk of epididymitis than the IUC group (RR = 0.55, 95% CI, 0.18-1.63).

CONCLUSION
Long-term IUC use was associated with a higher incidence of UTI in people with SCI. As compared to those with IUC, a lower risk of UTI was found in persons with SPC. These findings may have implications for shared clinical decision-making.


Although the lighter course of diphtheria in vaccinated patients, compared with unvaccinated ones, is generally recognized, however, there are two opinions regarding the comparative characteristics of the acute period of diphtheria in those vaccinated with diphtheria toxoid and unvaccinated ones. Some believe that active immunization does not have any effect on the duration of the first (acute) period and, consequently, the cleansing of the pharynx from raids, the improvement of the general condition occurs in the same time as in unvaccinated (E. M. Borok, N. A. Nikitina, N. I. Nisevich). Others note that in the actively immunized, the acute period proceeds more favorably: the raids go down faster, the general condition improves earlier than in the unvaccinated, and the one-sidedness of the tonsils is more often observed in the picture of the throat (A.D. Levasheva, V. N. Azbelev, N. P. Kudryavtseva, N. K. Belaya, V. L. Olshevskaya, E. M. Dmitrieva-Ravikovich, S. N. Rozanov). At the same time, in a larger number of cases, there is a discrepancy between the severity of the general condition and the amount of plaque (with severe intoxication, the raids are limited, localized).


Multilayer insulation forms the outer barrier of a satellite towards space. Polymer foils used in multilayer insulation have to withstand the space environment for mission durations often lasting well above 10 years. This paper outlines the space environmental test campaign performed to qualify novel and advanced polymer foils to reduce blanket mass and replace export-controlled materials. Complete multilayer insulation layups were irradiated; these were composed of thicker outermost layers of the reference material Kapton®, a white polyimide and an alternative, conductive black polyimide and up to seven thin internal, aluminized 6  μm or 3  μm polyethylene terephthalate and polyethylene naphthalate layers separated by nonwoven spacers. One sample set consisted of 25  μm polyether-ether-ketone foil and 6  μm internal vacuum-deposited-aluminum-coated polyether-ether-ketone layers. Materials were exposed to ultraviolet, electrons and protons simulating a 15-year geostationary orbit mission. Absorptance was ...


Background : Media exposure is an important driver of the innovation diffusion and has a significant impact on any opportunity for a reader, viewer, or listener to see or hear an advertising message in a particular media vehicle. There are many ways in which media can support and inform nursing and the greater healthcare community. The factors that may facilitate or influent performance of the behavior in using media will explore the opinion of nursing students in three countries of Asia in this research. Objectives: The purposes of this research were to study 1) the relationship of genders, age, year class, internship experience and the behavior level of media exposure nursing students Thailand, the republic of Union Myanmar and Indonesia, and 2) the influence of genders, age, year class, and internship experience with media exposure behavioral of nursing students Thailand, the Republic of Union Myanmar, and Indonesia. Methods: The survey approach was used for conducting answers via online during January-May 2015. The field studies were located 1) at Boromarajonani College of Nursing Nakhon Ratchasima, Saraburi, Chakrirat Ratchaburi, and Bangkok in Thailand (n = 1374), 2) at University of Nursing Rangoon and Mandalay in the Republic of Union Myanmar (n = 322), and 3) Indonesia at Stikes Bali, Stikes Hang Tuah Tanjung Pinang, and Stikes Bukit Tinggi of West Sumatra (n = 736) . Included 2,432 participants who were the nursing students in Bachelor Degree of Nursing science. The Cronbach???s Alpha method was used for reliability .814. Data were collected by using the quantitative information that was analyzed by using frequency, percentage, average, standard deviation, Spearman???s rho correlation analysis, Mann Whitney test and Kruskal Wallis test Results: The results showed that the samples were 12.91% male and 87.09% female of nursing students. The averages of ages were 20.14 year old ( SD = 2.72). Online media within a week, there are two media which the highest popular was Facebook ( M = 4.00, SD = 1.39), and Line ( M = 3.51, SD = 1.69). The analysis presented that 1.1) the relationship between age, gender, year class, and internship experience and behavior level of media exposure of nursing student Thailand were low correlated significant at .05, 1.2) the relationship between age, year class, internship in community and behavior level of media exposure of the republic of Union Myanmar were positively correlated a significant at .05, 1.3) the relationship of ages, gender and behavior level of media exposure were negatively correlated significant at .05 in nursing student Indonesia. Finally, Mann Whitney U test indicated that there is difference significant at .05 between gender (female and male), experience in patient care ward and community (yes, no), and behavior of media exposure. Kruskal Wallis test indicated the influence of ages, and year class with media exposure behavioral of nursing students had a differently significant at .05. Conclusion: Results of the hypotheses test at the statistical significance level of 0.05 suggested that behavioral media exposure is conceptualized as the type and frequency of using of social media. These behaviors are depend on ages, gender, year class, and internship experience which usage of media could concern the nature of context and culture of each country.


We study the existence of Z(3) metastable states in the presence of the dynamical quarks within the ambit of Polyakov quark meson (PQM) model. Within the parameters of the model, it is seen that for temperatures $T_m$ greater than the chiral transition temperature $T_c$, Z(3) metastable states exist ( $T_{m} \sim 310$ MeV at zero chemical potential). At finite chemical potential $T_m$ is larger than the same at vanishing chemical potential. We also observe a shift of ($\sim 5^\circ$) in the phase of the metastable vacua at zero chemical potential. The energy density difference between true and Z(3) metastable vacua is very large in this model. This indicates a strong explicit symmetry breaking effect due to quarks in PQM model. We compare this explicit symmetry breaking in PQM model with small explicit symmetry breaking as a linear term in Polyakov loop added to the Polyakov loop potential. We also study about the possibility of domain growth in a quenched transition to QGP in relativistic heavy ion collisions.


ABSTRACT We describe two new varieties of the North American species complex Packera paupercula (Michaux) Á. Löve & D. Löve (Asteraceae, Senecioneae): variety savannarum R. R. Kowal from the American upper Midwest and variety appalachiana A. M. Mahoney from the southeastern United States. The new combination P. paupercula var. pseudotomentosa (Mackenzie & Bush) R. R. Kowal from the Midwest is also established. Because of their pubescence, these varieties have been previously included within a broadly circumscribed P. plattensis (Nuttall) W. A. Weber & Á. Löve. Their recognition is based on a biosystematic study, which included morphological and ecological observations in the field and in a transplant garden experiment, and chromosome counts.


Generalized periodic epileptiform discharges (GPEDs) are a periodic electroencephalogram (EEG) pattern with bisynchronous sharp wave complexes occurring in periodic intervals between 0.5 and 4 seconds [1]. This EEG pattern has been described critically ill patients, often with metabolic or postanoxic encephalopathies, convulsive status epilepticus (SE), and progressive central nervous system diseases, including Creutzfeldt–Jacob disease (CJD) or subacute sclerosing panencephalitis (SSPE) [2]. Few studies have examined the clinical outcome of patients with GPEDs, but GPED pattern are believed to predict a grave outcome with a poor prognosis [3]. We present a case of 56-year-old man who admitted to our hospital because of viral encephalitis, he was found to have GPEDs on his EEG (Figure 1) with a good prognosis. A 56-year-old man presented to our emergency department because of paroxysmal dizziness associated with reaction retardation, dysphonia, sweating, and abnormal behavior. Each attack lasts 3–5 min. Family members later remembered that he caught herpes zoster virus 2 months before his admission. He had a long history of smoking, with occasional alcohol use, and he denied illicit drug use, but was otherwise healthy without any particular family history or past history such as cerebrovascular disease, endocarditis, or viral hepatitis. A subsequent EEG revealed GPEDs (Figure 1). On admission to our neurology department at the next day, he had no abnormal findings on nervous system and on physical examination. Admission laboratory data included a complete blood count revealing an elevated white blood cell count of 14.20 9 10/L (reference range, 4–10). His various biochemical indicators and tumor markerswere normal. A lumbar puncture was performed. Cerebrospinal fluid (CSF) pressure was not high, and CSF biochemical and conventional examination was normal. Additional tests on the patient's CSF were ordered, EB-VCA-IgA, TOXO-IgM, CMV-IgM produced positive results. CSF bacterial culture revealed a negative result. The patient's chest radiograph, brain computed tomography, computed tomography angiography, and magnetic resonance imaging revealed no focal abnormalities. A diagnosis of viral encephalitis with secondary epilepsy due to EEG and CSF result was reached. He was empirically started on antibiotics (cefuroxime) in treatment of infection. We immediately administered valaciclovir by oral, with corticosteroid by intravenous injection for antiviral therapies. Treated by oral carbamazepine with intramuscular injection phenobarbital, our patient's seizures resolved at the 4th day after admission. In the second EEG test (Figure 2A), the prior GPEDs had disappeared, while the epileptiform discharges were remains. EEG recorded again at the 8th day after admission (Figure 2B), it showed the presence of only a little sharp wave remains. The day before his discharge from hospital (at the 13th day after admission), one more EEG test was taken, it showed few sharp waves (Figure 2C). One month after his discharge from hospital, with treated by carbamazepine (0.1 g/bid) only, review of EEG revealed no abnormalities (Figure 2D). The patients had no more seizures. Generalized periodic epileptiform discharges are a rare EEG pattern composed of generalized, synchronous electrographic discharges, and earlier studies reported the incidence of GPEDs as 0.06–0.2% in adults included patients with both acute and chronic neurological disorders [4,5]. GPEDs are considered a unique EEG patterns that signify a severe, diffuse, and irreversible brain injury, occurring as an epiphenomenon in chronic neurological diseases, such as SSPE, CJD, neurosyphilis, or Lennox–Gastaut syndrome, or after an acute neurological insult caused by ischemia, hypoxia, or metabolic disturbances [5,6]. Such discharges are a characteristic but nonspecific EEG finding in cer-

Five surface flow wetland treatment systems were built in the 1990's to remove copper, nickel, cobalt and zinc from mine drainage in northeastern Minnesota. All but one of the drainages were neutral, and metal concentrations ranged from around 0.02 to 10 mg/l. Nickel was the primary metal generally accounting for about 90 % of the load. The one acid seep was pretreated with a peat / limestone bed prior to discharge to a surface flow wetland. System design, maintenance and performance of the wetland systems varied. Some systems have required essentially no maintenance and have produced water that has always been in compliance, while others have required a variance to maintain compliance and have required a considerable amount of reconstruction. All the systems included a series of berms to control the hydraulic gradient and to provide access to the wetland. Some of these berms included elaborate under drains, which were generally ineffective since only a small amount of the total flow could be transmitted. The key factor in performance was the size of the wetland. An areal nickel removal rate of about 40 mg/m 2 day was determined in pilot cell tests prior to wetland construction. In general, the systems that met this requirement produced the most consistent compliance with water quality standards.


A new Sr3(Si1−xAlxO4)O1−x/2◻x/2 (0.0 ≤ x ≤ 0.2) oxysilicate series has been prepared, existing as a single phase for x ≤ 0.11. The evolution of the cell parameters was smooth along the series. The crystal structure of Sr3(Si0.9Al0.1O4)O0.95◻0.05 was determined from neutron powder diffraction data at room temperature. This compound crystallizes in the P4/ncc space group, Z = 4, with a = 6.9427(1) A, c = 10.7992(1) A, and V = 520.53(1) A3. The Rietveld R values were RWP = 2.54% and RF = 1.33%. The Si4+/Al3+ aliovalent substitution is accompanied by oxygen vacancies for charge compensation. The crystal structure is described, as is a possible pathway for the "loosely bound" oxide anions that justifies the observed oxygen conductivity. Impedance data showed that the overall conductivity increased by more than 2 orders of magnitude from Sr3(SiO4)O to Sr3(Si0.89Al0.11O4)O0.945◻0.055. Further electrochemical characterization under various atmospheres (dry air, wet air, dry 5% H2 in Ar, and wet 5% H2 in Ar) and i...


A single protein molecule with one or more cysteine residues can occupy a plurality of unique residue and oxidation‐chemotype specified proteoforms that I term oxiforms. In binary reduced or oxidised terms, one molecule with three cysteines will adopt one of eight unique oxiforms. Residue‐defined sulfur chemistry endows specific oxiforms with distinct functionally‐relevant biophysical properties (e.g., steric effects). Their emergent complexity means a functionally‐relevant effect may only manifest when multiple cysteines are oxidised. Like how mixing colours makes new shades, combining discrete redox chemistries—colours—can create a kaleidoscope of oxiform hues. The sheer diversity of oxiforms co‐existing within the human body provides a biological basis for redox heterogeneity. Of evolutionary significance, oxiforms may enable individual cells to mount a broad spectrum of responses to the same stimulus. Their biological significance, however plausible, is speculative because protein‐specific oxiforms remain essentially unexplored. Excitingly, pioneering new techniques can push the field into uncharted territory by quantifying oxiforms. The oxiform concept can advance our understanding of redox‐regulation in health and disease.


Abstract Objective The aim was to compare the short-term (30 days after surgery) and long-term (over 6 months' follow-up) postoperative safety of off-pump and on-pump coronary artery bypass grafting (CABG) for patients with coronary heart disease (CHD). Methods Relevant randomized controlled trials (RCTs) were obtained from PubMed, Embase, Springer, Ovid, and Cochrane library up to July 2013. Odds ratios (ORs) with their 95% confidence intervals (CIs) were used to access effect sizes. Results Seven RCTs involving 9,128 patients were included. Results suggested no significant difference in all the short-term outcomes (mortality, OR = 0.90, 95% CI: 0.69 to 1.16, p = 0.41; myocardial infarction, OR = 0.95, 95% CI: 0.79 to 1.15, p = 0.61; stroke, OR = 0.78, 95% CI: 0.56 to 1.07, p = 0.12; renal failure, OR = 0.84, 95% CI: 0.60 to 1.18, p = 0.43; revascularization: OR = 1.95, 95% CI: 0.79 to 4.85, p = 0.15) and some long-term outcomes (mortality, OR = 1.02, 95% CI: 0.86 to 1.22, p = 0.81; myocardial infarction, OR = 0.86, 95% CI: 0.70 to 1.04, p = 0.12; stroke, OR = 0.89, 95% CI: 0.67 to 1.19, p = 0.44) between off-pump and on-pump CABG. However, off-pump CABG had a significantly higher revascularization rate (OR = 1.45; 95% CI: 1.02 to 2.06; p = 0.04) than on-pump CABG in long-term follow-up. Conclusion Short-term postoperative safety was similar between off-pump and on-pump CABG. A high revascularization rate was the drawback of off-pump CABG for CHD patients in long-term follow-up.


A number of recent works have employed decision trees for the construction of explainable partitions that aim to minimize the $k$-means cost function. These works, however, largely ignore metrics related to the depths of the leaves in the resulting tree, which is perhaps surprising considering how the explainability of a decision tree depends on these depths. To fill this gap in the literature, we propose an efficient algorithm that takes into account these metrics. In experiments on 16 datasets, our algorithm yields better results than decision-tree clustering algorithms such as the ones presented in \cite{dasgupta2020explainable}, \cite{frost2020exkmc}, \cite{laber2021price} and \cite{DBLP:conf/icml/MakarychevS21}, typically achieving lower or equivalent costs with considerably shallower trees. We also show, through a simple adaptation of existing techniques, that the problem of building explainable partitions induced by binary trees for the $k$-means cost function does not admit an $(1+\epsilon)$-approximation in polynomial time unless $P=NP$, which justifies the quest for approximation algorithms and/or heuristics.

Due to the development of nanotechnology graphene and graphene-based nanomaterials have attracted the most attention owing to their unique physical, chemical, and mechanical properties. Graphene can be applied in many fields among which biomedical applications especially diagnostics, cancer therapy, and drug delivery have been arousing a lot of interest. Therefore it is essential to understand better the graphene-cell interactions, especially toxicity and underlying mechanisms for proper use and development. This review presents the recent knowledge concerning graphene cytotoxicity and influence on different cancer cell lines. Novoselov et al. first described graphene in 2004 as monocrystalline graphitic film and received Nobel Prize in 2010 for the exploration of its exceptional properties [1]. The discovery of graphene became a new driving force in the development of nanoindustry [2, 3]. Graphene is a single-atom-thick, two-dimensional sheet of sp 2-hybridized carbon atoms arranged in a regular hexagonal pattern like in honeycomb structure (Figure 1) [4–9]. Graphene conducts heat and electricity extremely well [2] and as one of the carbon allotropes it is considered the thinnest and strongest known material [10]. The ratio of thickness of graphene sheet to the size of its surface differentiates this material from all other known nanomaterials [10]. The unique physicochemical properties of graphene are large surface area (2630 m 2 /g), extraordinary electrical (mobility of charge carriers, 200,000 cm 2 V −1 s −1) and thermal conductivity (∼5000 W/m/K), extremely high mechanical strength (Young's modulus ∼1100 Gpa), and possibility of mass-production at low cost [4, 11–13]. The perfect electronic transport properties and high surface-to-volume ratios are responsible for its exceptional mechanical and rheological properties and resistance to degradation. Graphene has two active sides which are surfaces and edges that improve the attachment of biological molecules to graphene and its adhesion to the cells [11]. Graphene has higher ratio of peripheral to central carbon atoms than similar nanomaterials. Consequently atoms at the edge allow better interaction with cell membranes and interference with cell metabolism [14]. Unlike other carbon allotropes, that is, fullerenes or carbon nanotubes, graphene exhibits unique chemical and physical properties closely related to the possibility of its surface functionalization which makes it more biocompatible and less toxic [15]. Graphene and graphene-based nanomaterials are today applied in numerous fields for purposes including nanoelec-their unique mechanical properties, such as high elasticity, flexibility, and adaptability for tissue engineering graphene family nanomaterials (GFNs) have been investigated in several biomedical applications especially cancer …


The results obtained to date involving the use of in methods to facilitate wide hybridization in plants are voluminous and impressive. The techniques of embryo culture, ovule culture, and in pollination and fertilization represent an extension of the normal sexual hybridization process. Successes recorded in obtaining hybrids stem largely from circumventing prezygotic or postzygotic hybridization barriers. Numerous recent successful hybridizations were possible because of the development of improved tissue and cell culture systems for crop plants and attention given to genotypes used in hybridization attempts. Interspecific and intergeneric hybridization utilizing the process of protoplast fusion will bypass the limits set by all sexual me'thods. In addition to combining complete genomes from two different species through protoplast fusion, this system affords unique opportunities for creating novel cytoplasmic combinations, transfer of individual chromosomes, transfer of cytoplasmic organelles, manipulation of male sterility, and for single gene transfer. Some caution must be noted with regard to the extent of hybridization possible between distantly related species. Although practically no limit exists to the physical fusion of protoplasts from widely divergent species, the restrictions imposed by somatic incompatibility have not been adequately addressed. Regeneration of plants from the protoplast or single heterokaryon level is still a major hurdle for many important crop species before somatic cell fusion can be exploited to produce interspecific and intergeneric hybrids. Identification and selection of hybrids is also a limitation to the efficient application of cell fusion methods.


A one-dimensional electronegative plasma situated between two symmetrical parallel electrodes under DC bias is studied by Particle-In-Cell simulation with Monte Carlo Collisions. By varying the electronegativity α≡n−/ne from the limit of electron-ion plasmas (negative ion free) to ion-ion plasmas (electron free), the sheaths formation, the negative ion flux flowing towards the electrodes, and the particle velocities at the sheath edges are investigated. Depending on α, it is shown that the electronegative plasma behavior can be described by four regimes. In the lowest regime of α, i.e., α < 50, negative ions are confined by two positive sheaths within the plasma, while in the higher regimes of α, a negative sheath is formed and the negative ion flux can be extracted from the bulk plasma. In the two intermediate regimes of α, i.e., 50 < α < 105, both the electron and the negative ion fluxes are involved in the neutralization of the positive ions flux that leaves the plasma. In particular, we show that the ...


The rapid increase in population growth due to industrialization and urbanization has resulted in air quality deterioration in Pakistan. Consequently, a considerable increase has been seen in the types of sources of air pollutants. However, the air quality of the country has deteriorated in the absence of management capabilities against air quality. Evidence from numerous governmental organizations and international bodies has specified that the environment, health, and quality of life are at high risk due to air pollution. Although the government of Pakistan established the Pakistan Clean Air Program, along with continuous monitoring stations to manage the quality of ambient air, air quality values have not yet been achieved. The present investigations were made in the city of Faisalabad in selected locations. Sampling of a 24 h average was done for selected sites. The air quality parameters such as NO2, SO2, COx, O2, noise level, and suspended particulate matter (SPM) were measured at two locations, i.e., Khurrianwala and Liaqatabad in the Faisalabad District. The measured values of air quality parameters were compared with national environmental quality standards (NEQS). Air pollutants such as SPM, SO2, and noise levels were found to be significantly higher than the 24-h standards of NEQS, which poses harmful effects on the quality of air and health, whereas the O2 concentration was found to be lower than the normal values, and NO2 and COx values were normal. The SO2, CO2, noise level, SPM, and O2 values ranged from 418–652 and 423–661 µg/m3, 3.03–3.44 and 3.08–3.51 mg/m3, 68–73 and 69–75 dB, 555–667 and 581–682 µg/m3, and 19.5–20 and 19.5–20.3 % for summer and winter season, respectively, as compared to standard values (150 µg/m3, 10 mg/m3, 65 dB, 550 µg/m3 and 21%). After the complete analysis of the selected locations, it was concluded that the ambient air quality of this area is severely degraded due to industrial as well as other commercial activities. These significant variations in air quality parameters suggest that there is a need to check the air quality regularly to take appropriate measures for reducing ambient air pollutants, especially in industrial areas as well as commercial areas.


understandable, but some of the information, particularly on Royal Naval officer training, is wrong. Not only is there no mention of the special entry officer scheme, the college where they were trained (RNC Keyham) is ascribed the function of training engineer officers. In fact, the split of engineering from the executive branch, the 'Great Betrayal', and the establishment of Royal Naval Engineering College Keyham did not occur until the 1920s. This book should find a place on the shelf of anyone with more than a passing interest in the naval aspects of the First World War, and will inevitably be repeatedly consulted. It is to be hoped that a second edition will address its few faults.


The purpose of the paper is to present a formal comparison of a variety of multiple regression models in technology forecasting for wireless communication. We compare results obtained from multiple regression models to determine whether they provide a superior fitting and forecasting performance. Both techniques predict the year of wireless communication technology introduction from the first (1G) to fourth (4G) generations. This paper intends to identify the key parameters impacting the growth of wireless communications. The comparison of technology forecasting approaches benefits future researchers and practitioners when developing a prediction of future wireless communication technologies. The items of focus will be to understand the relationship between variable selection and model fit. Because the forecasting error was successfully reduced from previous approaches, the quadratic regression methodology is applied to the forecasting of future technology commercialisation. In this study, the data will show that the quadratic regression forecasting technique provides a better fit to the curve.

This paper presents a novel frequency-domain energy detection scheme based on extreme statistics for robust sensing of OFDM sources in the low SNR region. The basic idea is to exploit the frequency diversity gain inherited by frequency selective channels with the aid of extreme statistics of the differential energy spectral density (ESD). Thanks to the differential stage the proposed spectrum sensing is robust to noise uncertainty problem. The low computational complexity requirement of the proposed technique makes it suitable for even machine-to-machine sensing. Analytical performance analysis is performed in terms of two classical metrics, i.e. probability of detection and probability of false alarm. The computer simulations carried out further show that the proposed scheme outperforms energy detection and second order cyclostationarity based approach for up to 10 dB gain in the low SNR range.


Undoubtedly, when solving the issue of early termination of the powers of the body of self-organization of the population, it will be necessary to be guided by the basic law, but the existence of a situation in which one legislative act defines some grounds, and another provides a broader list, in our opinion, creates problems of violation of legal technique when solving this issue. In our opinion, these grounds should be either identical, or in the matter of regulating the administrative-legal status of self-organization bodies, the Law of Ukraine «On Local Self-Government in Ukraine», in terms of early termination of powers, should contain blanket norms. At the same time, the legislator must in any case settle this issue in order to avoid double interpretation of this provision.Therefore, the bodies of self-organization of the population are an independent institution of local self-government, the activity of which is aimed at building an effective and developed public environment within the boundaries of the defined administrative-territorial unit independently by residents and their representatives to improve the quality of life, provide housing and communal and other services, improve the state socio-cultural, infrastructural development of the territory and acceptance of active participation in the co-design of development programs.Peculiarities of self-organization bodies: 1) they are a tool of local democracy; 2) take an active part in the implementation of the reform of decentralization and access to resources; 3) ensure control and quality of services for residents of the respective unit; 4) are in permanent and close relationship with village, settlement and city councils; 5) maximally take into account the needs of the local community and defend them in cooperation with public authorities; 6) contribute to a more active solution of local problems and contribute to the development of this territory.


In this paper, the consensus tracking problem of discrete distributed parameter multi-agent systems are studied. The communication topology of the system remains unchanged, and only some agents can directly obtain the trajectory information of the virtual leader. An iterative learning control law including the consensus error between any two agents in the system is designed, and the convergence condition of the algorithm is obtained with the help of the contraction mapping principle. In the sense of L2 norm, the consensus tracking error among all agents in the system can converge to zero along the iteration axis. Finally, simulation examples prove the applicability of the algorithm.


: The issue of development in its various concepts is of great importance at the global level, especially in the recent period, as it has been noticed a growing international interest towards the need for sustainable development to reach a sustainable future, after the world was heading towards a group of potential human and environmental disasters, global warming, environmental deterioration, and increasing Population growth, poverty, loss of biodiversity, widespread desertification, and other environmental problems are inseparable from the problems of human well-being and from the process of economic development in general, as many of the current forms of development are limited to the environmental resources on which the world depends. The close link between the environment and development led to the emergence of a concept of development called "sustainable development", as the fourth principle approved by the Rio de Janeiro Conference in 1992 indicated that: "In order for sustainable development to be achieved, environmental protection should be an integral part of the development process and cannot be thought of in isolation." about him.(1) Also, solar energy projects aim to consume between 80 and 85% of the energy produced for local development, because the region will need in 2050 more energy than Western Europe consumes now, and it will need quantities of water within 3 times the size of the Nile River, and this does not It can only be obtained through the desalination of sea water.

The Lower Permian (Wolfcampian) cycles of Kansas are broadly similar to the better known Upper Pennsylvanian (Missourian) cyclothems of the midcontinent. The morphological features of paleosols within five successive variegated mudstone units of the Council Grove and Chase Groups have been described in detail. A consistent pattern has emerged with aridic paleosols near the bases of the mudstones intervals and vertic paleosols toward the tops. The lower paleosol profiles are typically calcareous with well-developed carbonate accumulation (Bk) horizons. These may contain carbonate nodules, rhizocretions, or less commonly calcretes (K-horizons). Drab haloed root races are a common feature of these grayish reddish brown B horizons. The reddish color records oxidation under fairly well drained conditions, the underlying greenish gray horizons probably indicating the average position of the water table. Thin greenish gray to gray elluvial (E) horizons are preserved at the tops of many profiles. The upper paleosols within each variegated interval are characterized by well-developed vertic structures. Pedogenic slickensides, pseudoanticlines, and occasional gilgai result from the expansion and contraction of the soil such as occurs in a seasonal wet/dry environment. These paleosols are greenish gray to olive gray and often have abundant concertina root traces. The absence of a redmore » oxidized horizon suggests more poorly drained conditions. The upward trend from drier, better drained soils to vertic, poorly drained soils could have been generated by short-term climate change toward increasing, though still seasonal, precipitation. If so, this observation suggests that cyclic climatic change may have been an important factor in generating Lower Permian cyclothems. Such a conclusion is consistent with other evidence that the limestone and shale facies of these cyclothems were deposited in consistently shallow depositional environments.« less

Network coding is becoming an emerging communication technology by means of providing performance improvement in terms of throughput and energy efficiency. As majority of coding aware routing schemes centers on maximizing the coding opportunities, In this paper we have to optimize the benefits of network coding in the opportunistic routing. We propose a Adaptive coding aware routing Algorithm (ACAR) to encode the packets in two different flows that will not have the intermediate nodes. F-ACAR Algorithm select the optimal and adaptive encoder node from any one of the distinct flow and SACAR select any node which will be the neighbouring of the forwarding nodes of two distinct flows based on the anypath cost, delay and bandwidth estimation metrics. Due to this estimation ACAR can able to identify the high throughput and high packet delivery paths. We implement the F-ACAR and S-ACAR protocol in NS2 and compared with High throughput coding Aware routing Algorithm (HCOR). Simulation results show that bandwidth constrained adaptive coding aware routing Algorithm provides higher throughput than other coding aware routing algorithm.

The autonomous real-time optical navigation of planetary unmanned aerial vehicle (UAV) is of the key technologies to ensure the success of the exploration. In such a GPS-denied environment, vision-based localization is an optimal approach. In this article, we proposed a terrain aided simultaneous localisation and mapping (SLAM) algorithm, which simultaneously reconstructs the 3-D map point of environment and estimates the location of a planet UAV based on preexisting digital elevation model (DEM). To directly georeference the onboard UAV images to the digital terrain model, a theoretical model is proposed to prove that topographic features of UAV image and DEM can be correlated in the frequency domain via cross power spectrum. To provide the six-DOF of the UAV, we developed an optimization approach, which fuses the geo-referencing result into an SLAM system via local bundle adjustment (LBA) to achieve robust and accurate vision-based navigation even in featureless planetary areas. To test the robustness and effectiveness of the proposed localization algorithm, a new dataset for planetary drone navigation is proposed based on simulation engine. The proposed dataset includes 40 200 synthetic drone images taken from nine planetary scenes with related DEM query images. Comparison experiments are carried out to demonstrate that over the flight distance of 33.8 km, the proposed method achieved an average localization error of 0.45 m, compared to 1.32 m by ORB-SLAM2 and 0.75 m by ORB-SLAM3, with the processing speed of 12 Hz, which will ensure real-time performance. We will make our datasets available to encourage further work on this topic.


PurposeThe purpose of the paper is to improve the rating prediction accuracy in recommender systems (RSs) by metric learning (ML) method. The similarity metric of user and item is calculated with gray relational analysis.Design/methodology/approachFirst, the potential features of users and items are captured by exploiting ML, such that the rating prediction can be performed. In metric space, the user and item positions can be learned by training their embedding vectors. Second, instead of the traditional distance measurements, the gray relational analysis is employed in the evaluation of the position similarity between user and item, because the latter can reduce the impact of data sparsity and further explore the rating data correlation. On the basis of the above improvements, a new rating prediction algorithm is proposed. Experiments are implemented to validate the effectiveness of the algorithm.FindingsThe novel algorithm is evaluated by the extensive experiments on two real-world datasets. Experimental results demonstrate that the proposed model achieves remarkable performance on the rating prediction task.Practical implicationsThe rating prediction algorithm is adopted to predict the users' preference, and then, it provides personalized recommendations for users. In fact, this method can expand to the field of classification and provide potentials for this domain.Originality/valueThe algorithm can uncover the finer grained preference by ML. Furthermore, the similarity can be measured using gray relational analysis, which can mitigate the limitation of data sparsity.


Several environmental companies consider phenols compounds to be very dangerous pollutants because they are highly toxic and non-biodegradable, notably their high toxicity in water. For this reason, several processes have been studied by researchers to understand the mechanisms of elimination of phenolic compounds. Adsorption remains the best technique due to its characteristics, in fact, it is non-destructive and simple to use as well as have more other advantages, such as practicality and efficiency and low cost, Therefore, these methods need to be wi - dely developed on an industrial scale to remove phenol derivatives and achieve wastewater quality in accordance with standards. On the other hand, the development of these adsorption methods is highly dependent on new re - search on materials from abundant natural resources, namely apatites or biomaterials.

Electronic mail: email@example.com Abstract The mechanical and electrical properties of CdTe tetrapod-shaped nanocrystals have been studied with atomic force microscopy. Tapping mode images of tetrapods deposited on silicon wafers revealed that they contact the surface with the ends of three arms. The length of these arms was found to be 130 ± 10 nm. A large fraction of the tetrapods had a shortened vertical arm as a result of fracture during sample preparation. Fracture also occurs when the applied load is a few nanonewtons. Compression experiments with the AFM tip indicate that tetrapods with the shortened vertical arm deform elastically when the applied force was less than 50 nN. Above 90 nN additional fracture events occurred that further shorted the vertical arm. Loads above 130 nN produced irreversible damage to the other arms as well. Current-voltage characteristics of tetrapods deposited on gold indicated semiconducting behavior with a current gap of ~2 eV at low loads (<50 nN) and a narrowing to about 1 eV at loads between 60 and 110 nN. Atomic calculation of the deformation suggests that the ends of the tetrapod arms are stuck during compression so that the deformations are due to bending modes. The reduction of the current gap is due to electrostatic effects, rather than strain deformation effects inside the tetrapod.


The main objective of this project is to add mobility and automation to the process of managing Student information in an institute. In a real-world environment, such as a college campus, information is disseminated to students in the form of notices, handwritten manuals, and vocal messages. Today, it is critical to employ not only the traditional forms of statement, but also newer ones, such as cell phone technology, to facilitate faster and easier communication among students. The college staff uses android devices to upload results and college information to a secure android application. Before any record changes, all data is thoroughly examined and validated on the server. The college Administrator manages the MYSql Database, where all data is safely kept. The method reduces paperwork and the amount of time it takes to access student records. In the previous system, college depended mainly on paper records, which had its own set of drawbacks. At the same time while searching any information it is too difficult to access and takes a lot of time to search the particular website. Hence, in order to overcome this problem a smart phone-based application using Android can be used to make this process easy and secure.

Abstract Objective: The aim of this in vitro study was to investigate the influence of the adjacent tooth surface on pen type laser fluorescence (LFpen) and light-emitting diode (LED) device readings in detecting approximal caries lesions in permanent teeth. Background data: Early detection of noncavitated dental caries is important, because disease progression can be easily halted at this stage with certain applications, such as fluoride therapy, antibacterial therapy, dietary changes, or low-intensity laser irradiation. Materials and methods: A total of 87 permanent molars with 156 approximal surfaces were assessed with LED- and LF-based devices in contact with sound tooth surfaces (the control group) as well as approximal amalgam, composite, zirconia, and full ceramic restorations. All teeth were assessed once by one trained examiner. After the LF and LED assessments, the teeth were histologically evaluated using stereomicroscopy as the gold standard. The sensitivity, specificity, accuracy, and area un...


Submitted for the DAMOP19 Meeting of The American Physical Society Arbitrary internal state control of molecular ions through optical pumping1 PATRICK STOLLENWERK, IVAN ANTONOV, SRUTHI VENKATARAMANABABU, BRIAN ODOM, Northwestern University — Despite the significant challenges associated with controlling the internal modes of molecules, a number of successful techniques for efficiently populating the rovibrational ground state have been demonstrated. Fewer techniques have been implemented for arbitrary state control and none have been used to sustain high energy rotations. Robust, sustainable, arbitrary state preparation is especially useful for trapped ions as they are capable of long trapping lifetimes. We demonstrate a technique relying on spectral pulse shaping of a single broadband laser for populating arbitrary target rotational states of SiO+ up to rotational quanta exceeding N=65 including ground state preparation with sub-Kelvin internal temperatures. Additionally, the technique is extended to populating the first excited vibrational mode. In contrast to coherent manipulation or selective filtering methods, optical pumping represents a driven, dissipative method of control and therefore, neglecting chemical reactions, population in the target state can be sustained indefinitely. We also discuss some of the potential applications of control as well as our progress on direct fluorescent imaging of SiO+. 1Supported by NSF and ONR Patrick Stollenwerk Northwestern University Date submitted: 01 Feb 2019 Electronic form version 1.4


The majorpurpose of the study is to evaluate the Bardis Familism Scale through the use offactor analysis in order to determine whether all the items in the scale are unidimensional or multidimensional. Subsequent to the development of the scale, some suggested that it measures not just one but as many as five dimensions of familism. Data for the study were collected in 1975 from a sample of 586 college students from India. The results indicate that the scale consists of two separate subscales which are labeled Nuclear Familism and Extended Familism. Out of the 16 items, 10 measure the extendedfamily dimension and the remaining six measure the nuclearfamily dimension. These two subscales coincide exactly with Bardis' revised subscales. The analysis suggests that the scale is a strong indicator of the two dimensions offamilism. It is argued that the scale be used crossculturally to examine its validity before any revision is undertaken.


This study aims to describe the relationship between the socio-economic conditions of parents on student achievement. Methods and types of research using correlation and quantitative. The population as well as the research sample amounted to 28 students. The research instrument used a questionnaire and the learning achievement of students who took the Educational Profession course. The results showed that the average socioeconomic condition of the parents was 70 with good qualifications and the average learning achievement was 70 with good qualifications. Furthermore, testing using the product moment formula obtained rcount 0.900 and tcount 10.505 with degrees of freedom n-2 (28-2=26), and a significant level of 0.05. The hypothesis is accepted if tcount > ttable. Thus H1 is accepted because the test results prove that tcount is greater than ttable, namely 1,703 > 10,505. The conclusion is that there is a significant relationship between the socio-economic conditions of parents on the learning achievement of students' Educational Professions.

Objective: The objective of this research was to formulate and evaluate olanzapine (OLE) mucoadhesive microsphere prepared using carbopol and sodium combination. OLE having extensive hepatic first pass metabolism and low bioavailability problem, determined the need for the development of sustained release formulation. Methods: OLE mucoadhesive microspheres were prepared by ionic gelation method. OLE mucoadhesive microspheres were prepared by ionic gelation method by using calcium chloride as crosslinking agent. The OLE mucoadhesive microsphere was characterized by particle size measurement, process yield, morphology of microsphere, drug entrapment efficiency, mucoadhesion test, differential scanning calorimetry, powder X-ray diffraction, Fourier transforms infrared (FTIR) study and in-vitro drug release. Results: The OLE mucoadhesive microsphere having mean particle size ranged from 546.0 µm to 554.3 µm, and the entrapment efficiencies ranged from 73% to 96%. All the olanzapine (OLE) microsphere batches showed good in-vitro mucoadhesive property ranging from 75.89% to 96.47% and in the in-vitro wash off test ranging from 68.12% to 81.3%. FTIR studies indicated the no drug-polymer interactions in the ideal formulation F9. There were no compatibility issues, and the crystallinity of OLE was found to be reduced shoeing less intense peak in prepared mucoadhesive microspheres, which were confirmed by differential scanning calorimeter and X-ray diffraction studies. Among different formulations, the OLE microspheres of batch F9 had shown the optimum percent drug entrapment of microspheres. Release pattern of OLE from F9 microspheres batch followed Higuchi kinetic model. Stability studies were carried out for F9 formulation at 4°C/ambient, 25±2°C/60±5%, 40±2°C/75±5% relative humidity revealed that the drug entrapment, mucoadhesive behavior, and drug release were within permissible limits. Conclusion: The results obtained in this work demonstrate the use of carbopol and sodium alginate polymer for preparation of mucoadhesive microsphere. Keywords: Ionic gelation method, Gastroretentive delivery, Mucoadhesive microsphere, Carbopol.


Over the past few years having a broadband connection has become essential for many Internet activities. As broadband increases in importance, it becomes imperative to assess how its use and availability may vary, especially in relation to issues such as geographic location. For rural areas in particular, the availability of broadband service is especially important. This research assesses broadband service availability in rural areas of Pennsylvania, USA. In particular, it examines the extent to which Digital Subscriber Line (DSL) and broadband cable modem services are being deployed throughout rural Pennsylvania. It compares this deployment with the availability of such services in the state's urban and metropolitan areas. The results of this research suggest that there is a "digital divide" in terms of broadband availability between rural and urban areas of Pennsylvania. However, this "divide" is perhaps not as wide as might be expected. Thus, as broadband is becoming increasingly available in rural areas of the U.S. and throughout much of the rest of the world, this research concludes that while research must remain vigilant in terms of assessing advanced telecommunications availability in rural areas, future research should also be sure to focus on how such technologies can be used to promote economic and social concerns, including in relation to building online networks and diminishing social and professional isolation in rural areas.


Sparse approximate inverse (SPAI) preconditioners are effective in accelerating iterative solutions of a large class of unsymmetric linear systems and their inherent parallelism has been widely explored. The effectiveness of SPAI relies on the assumption of the unknown true inverse admitting a sparse approximation. Furthermore, for the usual right SPAI, one must restrict the number of non-zeros in each column to control the overall construction cost and this restriction can reduce the effectiveness of such preconditioners. To extend the applicability of SPAI, this paper proposes to use two-level preconditioning: possible dense columns of the true inverse, skipped by right SPAI (column-wise), will be better approximated by left SPAI (row-wise). Essentially, we approximate the true inverse by sparse matrices via a Gauss-Jordan like decomposition. Numerical experiments on a class of benchmark test matrices show that our new idea of two-level preconditioning can lead to a major enhancement to the standard SPAI method.


A 2-D analytic based eddy-current transient model for a conducting plate is derived that is capable of accounting for continuous changes in the input conditions. Only the source fleld on the surface of the conducting plate needs to be known. In addition, a 2-D steady-state analytic based eddy-current model that is capable of accounting for frequency and velocity changes in two directions is derived. Both analytic based models have been validated using flnite element code. The transient and steady-state models are integrated into an electromechanical system where the magnetic source is a Halbach rotor. The accuracy of both calculation methods is compared. The stifiness and damping coe-cients are derived using the steady- state model.

In this paper, we propose a decentralized feedforward initialization approach for iterative equalization methods, that decomposes a massive MIMO system into multiple smaller subsystems, where successively combining pairs of these systems and their solutions using the Jacobi method results in a high quality initial estimate for a following iterative detection method. In contrast to existing methods, this approach allows a computation of an initial estimate while the Gram matrix and matched filter output vector is not fully available. The BER performances show the effectiveness of this initialization method compared to approaches like maximum-ratio combining at high basestationto- client antenna ratios.


Horticultural consumers in Florida are interested in local and organically produced plants. But these terms can mean different things in different regions. UF/IFAS researchers conducted a survey last summer which suggests that consumers in central Florida define local as plants that are grown near where they are sold and identify the most important local benefits as product safety, quality, and community support. Organic plants are perceived as requiring fewer chemical additives and being healthier for the environment. The importance of these traits varies by plant type. This 5-page fact sheet was written by Hayk Khachatryan and Alicia Rihn, and published by the UF Department of Food and Resource Economics, April 2015.

We propose a hybrid network that combine point and distributed Brillouin sensors in an architecture that also deploys remote distributed Raman amplification to extend the sensing range. A 46-km proof-of-concept network is experimentally demonstrated integrating point vibration sensors based on fiber-optic tapers, with distributed temperature sensing along the network bus. The sensor network with a double-bus topology offers a higher optical signal to noise ratio and dynamic range than a single-bus for intensity point multiplexed sensors. In this network, we include low-cost intensity sensors that are able to measure vibrations in the 0.01 to 50 Hz frequency range, which are important in the monitoring of large infrastructures such as pipelines.

There are presented the results of comparative evaluation of sour cherry varieties of different ecological-geographical and genetic origin on the main biochemical parameters of fruits, condioning the taste of the fruit: dry substances, sugars, vitamins, anthocyanins. It was revealed the dynamics of content of biochemical parameters in fresh fruits depending on weather conditions of year, stresses of various type and biological peculiarities of cherry varieties. According to the obtained data in the conditions of southern horticulture (the Kuban zone of fruit growing of Krasnodar Territory) in the fruits of sour cherry varieties on average 14.5-17.0 % of dry substances, 6.4-8.4 % of sugars, 7.0-8.0 mg/100 g of vitamin C, 117.5-160.1 mg/100 g of substances with P-vitamin activity, 207.8-275.3 mg/100 g of anthocyanins accumulate. It was determined that fruits of sour cherry-sweet cherry hybrids and varieties of local breeding are characterized by higher content of biochemical parameters. It was established that the influence of a number of stresses – high positive temperatures, long periods of drought, surplus of rainfall during the period of fruits formation – causes an increase or decrease in content of some biochemical parameters, a decrease in weight, and deterioration in taste. It was determined that domestic varieties Kazachka, Kirina, Shalun`ya and Igrushka are distinguished by a high content of soluble solids (16.0-17.9 %) and carbohydrates (8.4-9.1 %). Cherry varieties Vstrecha, Alexa and Nord Star are characterized by an increased vitamin C content (8.3-9.7 mg/100); cherry varieties Kirina, Kazachka, Nefris, Vstrecha and the Shalun`ya – by a high content of anthocyans (247,0-333,8 mg/100) and P–vitamin activity (187.0-201.0 mg/100); varieties Alexa, Kirina, Shalun`ya and Igrushka are characterized by relatively large fruits (5.5-6.5 g). According to the optimal and harmonious combination of biochemical parameters, high taste (tasting score 4.6-4.8 points) and to the commodity qualities of fruits, sour cherry varieties Kirina, Alexa, Shalun`ya and Igrushka were recommended for laying raw plantings and production of fresh fruits and various types of processing in the conditions of southern horticulture.


An extended Belief-Desire-Intention (BDI) modeling framework is presented that the author has been developing for human decision-making and social behavior, effectively integrating engineering-, psychology-, and economics-based models. To mimic realistic human behaviors, attributes of the BDI framework are reverse-engineered from human-in-the-loop experiments conducted in the Cave Automatic Virtual Environment (CAVE). We will discuss various applications that the proposed modeling framework has been applied, such as 1) evacuation behaviors under a terrorist bomb attack, 2) pedestrian behaviors in the Chicago Loop area, 3) workforce assignment in a multi-organizational social network for community-based software development, 4) pedestrian behaviors in a shopping mall, 5) evacuation behaviors under fire in a factory, and 6) error detection and resolution by people in a complex manufacturing facility.

This chapter develops an eleventh "plague" onto Jacques Derrida's list of ten plagues of the New World Order in his Specters of Marx: the growing global climate crisis. Forging an amalgam from Derrida and Heidegger, it shows that the eleventh plague was not just "one more plague" but was at the heart of the first ten, or at least was intimately implied or caught up in them. In the most summary form, this would be to show that questions of violence, law, and social justice are inseparable from ecological sustainability. A similar move would demonstrate that another candidate for the eleventh plague—the animal holocaust—is closely connected both with the first ten plagues and ecological sustainability, perhaps serving as a bridge of sorts. Derrida's remarks about the animal holocaust, and about human suffering and misery, are set in the context of people's denial, blindness, and refusal to acknowledge these phenomena, and the way that human suffering especially represents the contradiction, the hidden waste, produced by an ever more efficiently functioning system.


We have studied the projections from the superior colliculus and the neocortex to the pulvinar nucleus in Galago senegalensis. by using the retrograde transport of horseradish peroxidase (HRP). Injections of various parts of the pulvinar complex, both the inferior and superior divisions, both the tectorecipient zone and the nontectorecipient zone as defined by Glendenning et. al. ('75), produce labeled cells in the lower tier of stratum griseum superficiale. The distribution of labeled cells in the superior colliculus varies with the locus of the injection, indicating a retinotopic projection system from the entire superior colliculus to all sectors of the pulvinar complex.

Submitted for the DFD08 Meeting of The American Physical Society Bubble chains in magnetic fluids PHILIP YECKO, Montclair State University, WAH-KEAT LEE, Argonne National Laboratory — Interactions between small numbers of bubbles of non-magnetic fluid immersed in a magnetic fluid (ferrofluid) are examined by direct numerical simulation using a volume of fluid (VOF) interface capturing method coupled to a magneto-quasistatic Maxwell solution. Constant magnetic susceptibility (linear magnetic material) is assumed and the Reynolds number is small, but does not vanish. For small gravitational and magnetic Bond numbers, the dynamics of multiple bubbles is controlled by the dipole fields induced by the bubbles, which for certain initial configurations leads naturally to the formation of linear chains of nearly spherical bubbles. The study of bubble chains using a VOF approach is facilitated by introducing multiple VOF phase functions, surpressing merger of bubbles. At larger Magnetic Bond numbers, the bubbles also elongate in the direction of the magnetic field, altering the coalescence process. Model results are shown to be in agreement with experiments performed using high resolution X-ray images of air bubbles in ferrofluid. The complementary problem of magnetic fluid droplets is also examined for its utility as a possible model for the microstructure of ferrofluids that can be used to predict their rheological properties, in particular the competition between shear and chain structures.

— Corrosion inhibitory performance of two Schiff bases prepared through condensation of two different amino acids, glycine and tyrosine with a common aldehyde, citronellal (designated as GCSB and TCSB, respectively) are compared by taking mild steel as test metal and aqueous H 2 SO 4 as the corrosive environment. Inhibition efficiencies as obtained through potentiodynamic polarization and electrochemical impedance spectroscopic methods establish TCSB as a superior corrosion inhibitor with 74 to 88 percentage of inhibition efficiency. Better corrosion mitigatory prowess of TCSB is explained in terms of various intrinsic molecular parameters, like the energy of frontier molecular orbitals (HOMO and LUMO), global hardness, softness, electrophilicity index, and others. It is revealed that two directional electron transfer, inhibitor to metal and retro-transfer, is responsible for the interaction of the Schiff bases with the metal surface. From electron distribution at HOMO and LUMO levels, atoms or functional groups present in the Schiff bases which initiate the molecular interaction with metal surface are ascertained.

ABSTRACT This paper examines travelers' preference for airline livery design, which is an important component of sensory experience for tourists. Based on surveys of both U.S. and South Korean respondents, this study finds that airline livery preference depends on travel purpose (i.e. business vs. vacation). Designs preferred by the two travel segments differ in terms of color tone, hue, line, and shape. Business traveler-preferred designs signal punctual, efficient, classy, and safe service; while vacation traveler-preferred designs elicit feelings of fun, friendly, and exotic service. It is also shown that travelers prefer airline livery that is congruent with their situational self-image, depending on the travel occasion at hand. In fact, self-image congruency of design is approximately half of the variance in airline livery preference. Finally, results show that self-image congruency also increases perceived service quality.


As a class of non-Newtonian fluids with yield stresses, Bingham fluids possess both solid and liquid phases separated by implicitly defined non-physical yield surfaces, which makes the standard numerical discretization challenging. The variational reformulation established by Duvaut and Lions, coupled with an augmented Lagrange method (ALM), brings about a finite element approach, whereas the inevitable local mesh refinement and preconditioning of the resulting large-scaled ill-conditioned linear system can be involved. Inspired by the mesh-free feature and architecture flexibility of physics-informed neural networks (PINNs), an ALM-PINN approach to steady-state Bingham fluid flow simulation, with dynamically adaptable weights, is developed and analyzed in this work. The PINN setting enables not only a pointwise ALM formulation but also the learning of families of (physical) parameter-dependent numerical solutions through one training process, and the incorporation of ALM into a PINN induces a more feasible loss function for deep learning. Numerical results obtained via the ALM-PINN training on one- and two-dimensional benchmark models are presented to validate the proposed scheme. The efficacy and limitations of the relevant loss formulation and optimization algorithms are also discussed to motivate some directions for future research.

This paper was designed to understand the implications and significance of management ethics over stock performance in Malaysia. The stock performance was measured using Return on Equity (ROE), Return on Asset (ROA), Earnings Per Share (EPS) and Price Earnings ratio (PE). A scorecard method used in ASEAN Corporate Governance report 2014 has been used to rank the firms based on their ethical performances. The published rankings for top 20 firms with good corporate governance are used as measure of management ethics. The theoretical relationship between shareholder's wealth, management ethics and efficient market hypothesis explains how management ethics impact the stock performance. The findings could be used to understand how shareholders could be affected by the managers' ethical or unethical behavior.


Among the atypical variants of Familial benign chronic pemphigus (FBCP) is the genital verrucoid variety. This condition is often misdiagnosed as condyloma accuminata. We present a case of a genital verrucoid variant of Hailey‐Hailey disease that was initially mistaken for condyloma accuminata. Multiple asymptomatic white bands in more than one fingernail were the first clue in diagnosing the condition, which was confirmed histopathologically. This nail marker may antedate any other cutaneous manifestation of FBCP. Nail examination for longitudinal leukonychia of fingernails might be of help in diagnosing atypical cases of Hailey‐Hailey disease.


In this work, we use a polished Gallium Nitride (GaN) based saturable absorber (SA) in the form of crystal structure. By incorporating the polished GaN film inside laser cavity with Erbium-doped fiber (EDF) as a gain medium, a stable Q-switched fiber laser was generated to operate at 1568 nm region. The repetition rate of the laser was tunable from 50.45 to 61.05 kHz while corresponding pulse width decreases from 7.42 to 6.1 μs as the 980 nm pump power rises from 84.02 to 125.23 mW. The maximum pulse energy was 29.29 nJ. To the best of our knowledge, this is the first report on the Q-switched fiber laser using Gallium Nitride (GaN) based saturable absorber (SA) that has a large application in ultrafast light generation.

Anticoagulant activity by a new synthetic substrate (MD805) during the hemodialysis can be assessed with the direct determination of plasma level. The result of an assay with a chromogenic substrate as antithrombin activity proved to be reproducible and precise levels on plasma samples taken in the hemodialysis with MD805 anticoagulation. Higher plasma level of MD805 during the hemodialysis than theoretical plasma concentration as that of APTT by the addition of MD805 in vitro. Therefore, the assay obtained from in vitro study was needed to obtain the same prolongation of plasma level of MD805 in hemodialysis could be introduced to individual requirement of the optimal dose of MD805 for the maintenance of adequate anticoagulation.


Coronary artery disease remains a major killer, with almost 117 000 deaths every year. In addition, many more people die from associated diseases such as heart failure, cardiomyopathy and aneurysm, among many others. Yet morbidity for all the major cardiac diseases has increased as mortality has decreased.
