A Scanning Electron Microscope Study Comparing the Effectiveness of Different Types of Sharpening Stones and Curets (1995)

The effects of various types of sharpening stones on standard carbon steel Gracey type curets, and the influence of the sharpened curets on periodontally involved root surfaces, during in vitro scaling and root planing, was evaluated by means of scanning electron microscopy (SEM). Six different sharpening stones of varying texture, two of aluminum oxide, two India, and two Arkansas stones were assigned to sharpen six groups of 10 curets each. The curets were first examined under SEM and photographed and all exhibited edge irregularities. They were then sharpened with the different stones and again examined and photographed using SEM. The sharpness of each instrument was graded, related to the type of stone used, and the data compared statistically. A positive correlation was found between the texture of stone used and the surface sharpness it produced on the cutting edge of the instrument. The curets were then used to root plane the root surfaces on periodontally involved, extracted teeth. Replicas of the root surfaces were examined with SEM before and after removal of the smear layer with 10% EDTA. The planed and cleaned root surfaces revealed the effects of the sharpened instruments, with the relative surface roughness of the instrument being imparted to the tooth surface. The curets sharpened with finger grit stones produced smoother surfaces than those sharpened with the rough or coarse grit stone. It may be concluded that the sharpness of curets is related to the type of sharpening stone used and in turn to the smoothness of the planned root.
Negative pH, efflorescent mineralogy, and consequences for environmental restoration at the Iron Mountain Superfund site, California (1999)

The Richmond Mine of the Iron Mountain copper deposit contains some of the most acid mine waters ever reported. Values of pH have been measured as low as -3.6, combined metal concentrations as high as 200 g/liter, and sulfate concentrations as high as 760 g/liter. Copious quantities of soluble metal sulfate salts such as melanterite, chalcanthite, coquimbite, rhomboclase, voltaite, copiapite, and halotrichite have been identified, and some of these are forming from negative-pH mine waters. Geochemical calculations show that, under a mine-plugging remediation scenario, these salts would dissolve and the resultant 600,000-m3 mine pool would have a pH of 1 or less and contain several grams of dissolved metals per liter, much like the current portal effluent water. In the absence of plugging or other at-source control, current weathering rates indicate that the portal effluent will continue for approximately 3, 000 years. Other remedial actions have greatly reduced metal loads into downstream drainages and the Sacramento River, primarily by capturing the major acidic discharges and routing them to a lime neutralization plant. Incorporation of geochemical modeling and mineralogical expertise into the decision-making process for remediation can save time, save money, and reduce the likelihood of deleterious consequences.
Sustained benefits of leuprolide acetate with or without subsequent medroxyprogesterone acetate in the nonsurgical management of leiomyomata uteri (1995)

Approximately one half of women with abnormal bleeding attributed to leiomyomata uteri have sustained symptomatic improvement after 6 months of therapy with LA even when only placebo therapy is given, although MPA decreases the incidence of anemia. Leuprolide acetate with or without subsequent progestin may be useful as a component of nonsurgical management of these tumors, with monitoring of hematologic status. The interpretability of these data is limited by the high rate of therapy discontinuation in women with abnormal bleeding of the severity studied here.
Epidermal cell kinetics of the pig: a review (1990)

Age-related changes in cell kinetic parameters for the epidermis of pigs have been shown to be small, indicating that young pigs may be used for experimental studies. It was not possible to draw any firm conclusions about any strain-related differences in the cell kinetics of the epidermis of the pig. Lower LI values have been quoted for the miniature pig and the Yorkshire pig than for the Large White pig. However, these differences may be related to variations in experimental technique. The cell kinetic data for the Yorkshire pig are not consistent. Very high values for the mitotic index suggested a high rate of cell turnover, whilst data from single pulse labelling and grain count halving studies indicate a relatively low rate of cell turnover. The results from continuous labelling studies on the epidermis of the Yorkshire pig suggest that the basal cell turnover time (TT) is a factor of two or more shorter (136 h) than the estimates obtained using other methods. In the Large White pig estimates of TT were similar using a variety of techniques and were comparable with the TT estimate for the Yorkshire pig obtained using the continuous labelling method. There is some degree of inconsistency in the literature with regard to possible diurnal variations in the cell kinetic parameters for the epidermis. In the study of Archambeau & Bennet (1984) distinct diurnal variations were found in the LI, although the reliability of this finding is questionable due to the small number of animals used. Later studies by Morris et al. (1987) have suggested that diurnal variations are negligible in the epidermis of the pig. The majority of labelled cells (80%) in pig epidermis are located in the basal layer, although a significant proportion (20%) occurs suprabasally, in the cell layer immediately above the basal layer. Therefore, the epidermis can be regarded as having a bilayered proliferative cell compartment. The results from studies on irradiated pig skin (Morris & Hopewell, 1986, 1988, 1989) are not consistent with the presence of a homogeneous proliferative compartment in the epidermis, and are best explained by the occurrence of an heterogeneous proliferative compartment consisting of a stem cell subpopulation and a much larger population of transit proliferative cells.

The sensitivity of indicators of thrombosis initiation to a bileaflet prosthesis leakage stimulus. (2001)

The results indicate that bileaflet valve leakage flow causes significant platelet disruption, that erythrocytes are more resistant to disruption by leakage flow than platelets and granulocytes, and that annexin V binding to platelets and plasma platelet factor 4 activity are more sensitive markers of leakage induced blood damage than plasma hemoglobin concentration.
Pixel Deconvolutional Networks (2017)

Deconvolutional layers have been widely used in a variety of deep models for up-sampling, including encoder-decoder networks for semantic segmentation and deep generative models for unsupervised learning. One of the key limitations of deconvolutional operations is that they result in the so-called checkerboard problem. This is caused by the fact that no direct relationship exists among adjacent pixels on the output feature map. To address this problem, we propose the pixel deconvolutional layer (PixelDCL) to establish direct relationships among adjacent pixels on the up-sampled feature map. Our method is based on a fresh interpretation of the regular deconvolution operation. The resulting PixelDCL can be used to replace any deconvolutional layer in a plug-and-play manner without compromising the fully trainable capabilities of original models. The proposed PixelDCL may result in slight decrease in efficiency, but this can be overcome by an implementation trick. Experimental results on semantic segmentation demonstrate that PixelDCL can consider spatial features such as edges and shapes and yields more accurate segmentation outputs than deconvolutional layers. When used in image generation tasks, our PixelDCL can largely overcome the checkerboard problem suffered by regular deconvolution operations.
Adaptive-rate transmission with coding and interleaving for a further improvement in the throughput of meteor-burst communication systems (2002)

The meteor-burst (MB) channel is characterized by its availability in time bursts and the exponential decay of the received signal within the majority of these bursts. There are different scheme for data transmission over this channel. Adaptive-rate (AR) transmission is known to provide the best throughput among all schemes for systems operating over this channel. In this paper it as shown that by using coding and interleaving a significant improvement in the throughput is feasible. In particular, the scheme is more effective for links with small decay constant such as those operating at the high frequency range of the meteor-bursts transmission or those operating at short distances.
Property-based testing of privileged programs (2002)

Addresses the problem of testing security-relevant software, especially privileged (typically, setuid root) and daemon programs in UNIX. The problem is important, since it is these programs that are the source of most UNIX security flaws. For some programs, such as the UNIX sendmail program, new security flaws are still being discovered, despite being in use for many years. For special-purpose systems with fewer users, flaws are likely to remain undiscovered for even longer. Our testing process is driven by specifications we create for the privileged programs. These specifications simultaneously define the allowed behavior far these programs and identify problematic system calls, regions where the program is vulnerable, and generic security flaws. The specifications serve three roles in our testing methodology: as criteria against which a program is sliced, as oracles against which it is tested, and as a basis for generating useful tests. Slicing is employed to significantly reduce the size of the program to be tested. We show that a slice of a privileged program (rdist) with respect to its security specifications is quite small. We introduce the Tester's Assistant, a collection of tools to mechanize the process of testing security-related C programs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Comparison of the prognosis indication of VEGFR-1 and VEGFR-2 and Tie2 receptor expression in breast carcinoma (2005)

The degree of angiogenesis in breast cancer has previously been shown to be an indicator of prognosis, and tumor microvasculature is a candidate target for new antiangiogenic therapies. The aim of this study was to investigate the prognostic value of vascular endothelial growth factor (VEGF) receptors, VEGFR-1 (Flt-1) and VEGFR-2 (KDR/Flk-1), and Tie2/tek receptor tyrosine kinase in breast carcinoma. VEGF receptors and Tie2 expression was investigated using immunohistochemical assays with monoclonal antibodies on frozen sections in a series of 918 and 909 patients respectively. VEGFR-1 and VEGFR-2 and Tie2 were correlated with long-term (median, 11.3 years) patients' outcome. Univariate (Kaplan-Meier) analysis showed that VEGFR-1 positive tumor surface (cutoff = 5%) was significantly correlated with high metastasis risk (p=0.03) and relapse (p<0.01) in all patients, and in those with node negative tumors (p<0.001 and p<0.01 respectively), but not with overall survival. In contrast Tie2 positive tumor surface (cutoff = 7%) was significantly correlated with poor overall survival (p=0.025) and also with high metastasis risk particularly among node negative patients (p<0.01). Moreover, Tie2 immunoexpression was significantly predictive of relapse (p=0.003) in the node negative subgroup (p=0.02). In multivariate analysis (Cox model), VEGFR-1 and Tie2 immunoexpressions were identified as independent prognostic indicators. In contrast, univariate analysis showed that VEGFR-2 positive tumor surface (cutoff = 10%) was not correlated with survival or with metastasis and relapse risk. Our results suggest that VEGFR-1 and Tie2 immunohistochemical expression permits the identification of patients with poor outcome, and particularly node negative ones with a high risk for metastasis and relapse. VEGFR-1 and Tie2 immunodetection may also be considered as potential tools for selecting patients who could benefit in the future from specific antiangiogenic therapy interfering with VEGFR-1 and Tie2 activation pathways.
RESPONSE OF VOLTA CHILDREN TO JET INOCULATION OF COMBINED LIVE MEASLES, SMALLPOX AND YELLOW FEVER VACCINES. (1964)

An earlier study established that Upper Volta children respond to vaccination with the Enders live attenuated measles strain in the same general fashion as do children in the USA. The present report describes a second pilot project carried out in Ouagadougou, Upper Volta. During this investigation various mixtures of live measles, smallpox and 17D yellow fever vaccines were introduced into susceptible infants by jet injection. Combining the attenuated virus vaccines did not alter or accentuate the characteristic clinical reactions elicited by the individual components, nor was there evidence of significant immunological interference. From this experience it is concluded that combined vaccination with these agents may be safely and effectively employed in larger programmes as the need dictates.
Efficient algorithm for early detecting all-zero DCT blocks in H.264 video encoding (2010)

In this paper, we presents an efficient algorithm for early detecting all-zero discrete cosine transform (DCT) coefficient blocks (AZB) by combining Parseval energy conservation theorem and the successive elimination algorithm (SEA). A mathematical inequality is derived from Parseval theorem and applying SEA for motion estimation. The simulation results show that the proposed algorithm achieves approximately a 12%~22% computational saving compared to the existing methods. Furthermore, when the proposed algorithm is implemented with other fast detection algorithms, it can further improve AZB detection ratio without any video-quality degradation.
Thoracoabdominal Asynchrony Is Not Associated with Oxyhemoglobin Saturation in Recovering Premature Infants (2016)

Recovering premature infants exhibited TAA regardless of need for ventilatory support and supplemental oxygen. TAA was not associated with SpO2% in either group. Maintenance of SpO2% does not require correction of TAA.
Leisure Participation and Leisure Satisfaction: Moderating Effects of Personality Traits (2009)

This study explored relationships among personality traits, leisure participation, and leisure satisfaction in a representative sample of community adults in Taiwan. We found that (1) personality traits of extraversion (E) and sensation-seeking (SS) were significantly related to greater overall leisure participation; (2) SS was significantly related to higher leisure satisfaction; and (3) personality traits of N and SS significantly moderated leisure participation-leisure satisfaction relationships. Implications of these findings for developing a Chinese psychology of leisure were discussed.
Optimization of biomass and lipid production in heterotrophic microalgal cultures (2012)

Microalgae are a promising source of biofuels and other valuable chemicals. The low cell density and slow growth rate that have traditionally characterized microalgal cultures, however, have resulted in a reduced economical feasibility. To develop a sustainable microalgal process it is required to increase culture productivity, maximize production yield, and reduce production costs. To achieve these goals it is necessary to improve the current understanding of the dynamic behaviour of microalgal cultures. In this thesis, growth and oil production rates in heterotrophic cultures of Auxenochlorella protothecoides were evaluated as a function of the carbon and nitrogen source concentration. It was found that nitrogen plays a major role in controlling the productivity of microalgae. It was also shown that there exists a nitrogen source concentration at which biomass and oil production can be maximized. A mathematical model that describes the effect of nitrogen and carbon source on growth and oil production was proposed, considering the uncoupling between nitrogen uptake and growth, the possibility of luxurious uptake of nitrogen, and the time-delayed inhibitory effects caused by the transient spike in the intracellular nitrogen concentration. Using a non-linear model-based optimization approach, biomass and oil productivities were substantially increased. The use of an adaptive model predictive control strategy resulted in a 10-fold increase in the average biomass productivity and a 16-fold increase in the maximum productivity compared to batch experiments. The final cell density in the optimized culture was 144 g/L (dry weight), with 49.4%w/w oil content. The maximum lipid productivity was 20.2g/Ld, achieved during the exponential growth phase at an average cell density of 86g/L. The lipid productivity in the optimized microalgal culture was higher than any previously reported productivity value for other oleaginous microorganisms. Application of the adaptive optimization strategy to a two-stage glycerol/glucose culture resulted in an increased production yield (glucose to oil), from 0.267g/g in the optimized single-stage culture to 0.347g/g in the two-stage culture. The increased yield and productivity of the optimized cultures resulted in a largely improved economic feasibility. Composition analysis of the algal oil produced in the optimized cultures shows that the oil has a high quality as biodiesel precursor, in terms of the expected cetane number, iodine value, and cold filter plug point temperature. The higher productivity and excellent lipid profile of the optimized microalgal culture make A. protothecoides an exceptional source for biodiesel production and a potential source of single cell oil for other applications.
Method for Optimal Placement of Sensors in a Wired Pipe Drillstring (2007)

Abstract This paper introduces a method for selecting the best sensor layout when using wired pipe for drilling operations. The introduction of wired pipe in drilling operations increases the data rate significantly compared to standard telemetry systems. Various sensors systems are available, measuring parameters such as drillstring vibration, drillstring torque, downhole fluid temperature and downhole annulus pressure. Also available are measurements from various logging tools placed as a part of the bottomhole assembly. The data from the sensors can contain important information that can be used for preventing various operational problems, such as high vibrations, insuﬃcient hole cleaning, kick incidents, and loss of circulation. The method described in this paper can be used for designing a sensor layout for a wired pipe drillstring. The method analyzes data available from the sensors to yield the information required to detect operational problems. The paper presents two different cases where the method is applied, one from a kick incident and the other from a loss of circulation incident. The results show that by optimizing the sensor layout for a wired pipe drillstring, cost eﬃcient performance can be ensured with regards to potential drilling problems.
Treatment of psoriasis with psoralens and ultraviolet A. A double-blind comparison of 8-methoxypsoralen and 5-methoxypsoralen. (1994)

Thirty-eight patients with plaque-type psoriasis were enrolled in a double-blind psoralen plus ultraviolet A (PUVA) treatment study comparing the efficacy and side effects of 5-methoxypsoralen (5-MOP) and 8-methoxypsoralen (8-MOP). Patients treated with 8-MOP healed significantly faster than those on 5-MOP for 6 weeks of treatment, but there was no significant difference after 9 weeks. There was no significant difference in side effects between the two groups, but nausea tended to be more common in the 8-MOP group. One patient on 5-MOP had signs of toxic hepatitis. The importance for maximizing absorption of taking 5-MOP with food is stressed, and PUVA treatment should be given 3 h after intake of the drug.
ÉTUDES NOUVELLES ENTREPRISES PAR ÉLECTRICITÉ DE FRANCE SUR L'ÉVAPORATION DES LACS ET RÉSERVOIRS (1966)

RÉSUMÉ Ces études sont orientées vers la détermination expérimentale de la capacité de dissipation d'énergie calorique par un plan d'eau dans différentes conditions climatiques. Des comparaisons de bilan d'eau et de bilan d'énergie ont été tentées à partir de mesures effectuées sur lac et sur bacs d'évaporation afin de mettre au point un dispositif de mesure adapté à létude, à une échelle de temps très fine, des conditions naturelles de l'évaporation et à lasimulation de l'évaoiration forcée sur un site. Deux campagnes d'essais rélisées, l'une sur un réservoir situé à BRENNILIS en Bretagne, l'autre sur le Lac de LA GODIVELLE (lac de craère dans le MASSIF CENTRAL), ont permis de préciser les problèmes techniques de divers orders auzquels se heurte l'étude de la dynamique de l'évaporation sur un plan d'eau dans la nature.
Acute Aortic Dissection During Cardiopulmonary Bypass (1974)

A review of over 950 open-heart operations done at St. Mary's Long Beach Hospital from July 1, 1969 through Sept 15, 1973, showed five instances of acute aortic dissection occurring during cardiopulmonary bypass. Three of these patients were successfully resuscitated and were long-term survivors. Routine femoral artery cannulation was carried out in 836 patients. All five dissections occurred in this group. None occurred in the 114 aortic arch cannulations, but three of these patients developed severe bleeding problems at the cannulation site, of which two died. Prompt diagnosis of the acute aortic dissection and immediate treatment were crucial to these patients' survival; vigorous postoperative antihypertensive medical management was likewise an important factor. The occurrence of intraoperative acute aortic dissection is not necessarily fatal if rapidly recognized and properly handled.
