Effect of Waste Ceramic Polishing Powder on the Properties of Cement Mortars

An innovative approach of reusing waste ceramic polishing powder generated in ceramic industries to develop admixture in cement was studied. Effects of waste polishing powder (PP) on compressive strength, pore structure, dry shrinkage ratio, heat of hydration and microstructures were studied comparing to fly ash (FA). Results show that waste polishing powder has high of pozzolanic activity than fly ash does. The cement mortar strength active index of PP is up to 83.6% and that of FA in experimental is only 72.3%. The addition of PP reduces the heat of hydration of cement and accelerates the early hydration of cement pastes. But the dry shrinkage of mortars increased obviously as the admixture of PP is increased, however, mixing compound PP and FA in mortars conduces to decrease the dry shrinkage of mortar. Microstructure analysis and mercury intrusion porosimetry of mortars further indicated that larger amount of hydration product is formed in mortars added polishing powder, which results in the low average pore diameter and the dense cement pastes.
Mueller-Hinton agar is superior to PDM blood agar for detection of methicillin-resistant Staphylococcus aureus.

The aim of this study was to compare the expression of oxacillin resistance in methicillin-resistant Staphylococcus aureus (MRSA) on Paper Disc Method agar supplemented with 5% defibrinated blood (PDM blood agar) and Mueller-Hinton agar supplemented with 2% NaCl (MH NaCl agar) using different susceptibility tests. Fifty mecA-containing isolates of S. aureus, exhibiting 46 different pulsed-field gel electrophoresis patterns, were comparatively tested using the E test, the single disk diffusion test, and the multipoint inoculation technique, under various culture conditions. The E test incubated at 35 degrees C for 24 h (breakpoint of resistance > or = 2.0 mg/L) detected 94% of the isolates on MH NaCl agar, compared with 28% for PDM blood agar (P < 0.05). The disk diffusion test (breakpoint < 10 mm in diameter) under these incubation conditions detected resistance in 100% of the isolates on MH NaCl agar and in 80% of the isolates on PDM blood agar (P < 0.05). The multipoint technique (breakpoint > or = 1 mg/L), applied at 35 degrees C for 24 h, detected 100% on MH NaCl agar and 46% on PDM blood agar (P < 0.05). Irrespective of the method of susceptibility testing evaluated, MH NaCl agar was superior to PDM blood agar for the detection of oxacillin resistance in mecA-containing S. aureus.
Experimental study of time series-based dataset selection for effective text classification

Conventional automatic document classification methods are currently faced with challenges in terms of learning time and computing power, owing to the ever-increasing amount of data on the web. In this paper, we propose an efficient classification method that uses time series-based dataset selection. In the proposed method, the dataset is split based on time series data and the best set of testing documents selected. The results of classification performance tests conducted using a Naïve Bayes classifier indicate that using a small amount of data divided in terms of time series is more efficient than using the entire dataset for learning.
Identification of Recalcitrant Hydrocarbons Present in a Drilling Waste-Polluted Soil

Abstract During spills of hydrocarbons in soil, it has been observed that aliphatic and the slightly aromatic hydrocarbons are first to be removed, however, branched aliphatic and aromatic compounds, polycyclic aromatic hydrocarbons (PAHs) and their similar heteroatoms with sulfur (PAS) remain strongly absorbed to soil particles. It is important to point out that studies of biodegradation of alkyl-substituted PAHs and PAS are scarce and most of them have been carried out using only available standard compounds. The aim of this investigation was to identify and to quantify the aliphatic, alkyl polycyclic aromatic, and sulfured recalcitrant fractions present in a contaminated soil with drilling wastes. A modified method of shaking-centrifugation extraction was implemented for the extraction of compounds from contaminated soil. The organic extract obtained was purified and fractionated using aluminum oxide. Gas Chromatograph with flame ionization detector (GC-FID) and Gas Chromatograph with mass spectrometer detector (GC-MS) identified the aliphatic, PAHs and PAS fractions. Hydrocarbon composition in the soil contaminated with 140,000 mg TPHs/Kg soil, consisted in 80% of branched aliphatic compounds of C10 to C22, 15% of alkyl PAHs, and 5% of PAS compounds. Lineal, lineal branched, and cyclic branched aliphatic hydrocarbons, as well as their alkyl naphthalene, anthracene and phenantrene, methyldibenzothiophene, dimethyldibenzothiophene, and dimethylnaphto[2,3-b]thiophene compounds were identified by CG-MS. The identification of compounds in soil P31, allowed us to speculate on the origin of the contamination and the natural attenuation that had occurred at this site.
A Compact Digital Pixel Sensor (DPS) Using 2T-DRAM

Received: 7 December 2010; in revised form: 14 March 2011 / Accepted: 21 March 2011 /Published: 28 March 2011Abstract: In digital pixel sensors (DPS), memory elements typically occupy large siliconarea of the pixel, which signiﬁcantly reduces the pixel’s ﬁl l factor while increases itssize, power and cost. In this work, we propose to reduce DPS memory’s area and poweroverhead by reducing the memory requirements with a multi-reset integration scheme, andmeanwhile employing a dynamic memory instead of traditionally exploited large 6T-SRAMcell. The operation of the DPS takes advantage from the chronological change of thecode, which results in reduced memory needs without affecting the light resolution. Inthe proposed implementation, a 4-bit in-pixel memory is used to reduce the pixel size, andan 8-bit resolution is achieved with multi-reset scheme. Inaddition, full complementarymetal-oxide-semiconductor (CMOS) 2T DRAM and selective refresh scheme are adoptedto implement the memory elements and further increase the area savings. This paperpresents the proposed multi-reset integration methodology and its implementation withdedicated memory circuits. Proposed architecture is validated by a prototype chip fabricatedusing AMS 0.35 µm CMOS technology. Reported experimental results are compared withrelative works.Keywords: image sensors; digital pixel sensors; pulse width modulation pixel; 2T-DRAM
Short communication : Eating and rumination activity in 10 cows over 10 days 1 2

Eating and rumination activities were evaluated in 10 Brown Swiss cows over 10 days, and the coefficients of variation (CV) were calculated for the investigated variables. A pressure sensor integrated into the noseband of a halter recorded jaw movements during chewing, which allowed the recording of eating and rumination times and the number of regurgitated boluses. The mean CVs ranged from 5.9 to 12.7% and were smaller for rumination (chewing cycles per bolus, 5.9%; daily number of cuds, 8.4%; rumination time, 9.1%) than for eating (eating time, 12.0%; chewing cycles related to eating, 12.7%). We concluded that of eating and rumination variables examined, the number of chewing cycles per regurgitated bolus is the most robust with little variation in individual cows.

Integer, fractional and fractal Talbot effects

Abstract Self-images of a grating with period a, illuminated by light of wavelength λ, are produced at distances z that are rational multiples p/q of the Talbot distance z T = a 2/λ; each unit cell of a Talbot image consists of q superposed images of the grating. The phases of these individual images depend on the Gauss sums studied in number theory and are given explicitly in closed form; this simplifies calculations of the Talbot images. In ‘transverse’ planes, perpendicular to the incident light, and with ζ = z/z T irrational, the intensity in the Talbot images is a fractal whose graph has dimension . In ‘longitudinal’ planes, parallel to the incident light, and almost all oblique planes, the intensity is a fractal whose graph has dimension . In certain special diagonal planes, the fractal dimension is . Talbot images are sharp only in the paraxial approximation λ/a → O and when the number N of illuminated slits tends to infinity.

Tumour oxygen dynamics measured simultaneously by near-infrared spectroscopy and 19F magnetic resonance imaging in rats

Simultaneous near-infrared spectroscopy (NIRS) and magnetic resonance imaging (MRI) were used to investigate the correlation between tumour vascular oxygenation and tissue oxygen tension dynamics in rat breast 13762NF tumours with respect to hyperoxic gas breathing. NIRS directly detected global variations in the oxygenated haemoglobin concentration (Δ[HbO2]) within tumours and oxygen tension (pO2) maps were achieved using 19F MRI of the reporter molecule hexafluorobenzene. Multiple correlations were examined between rates and magnitudes of vascular (Δ[HbO2]) and tissue (pO2) responses. Significant correlations were found between response to oxygen and carbogen breathing using either modality. Comparison of results for the two methods showed a correlation between the vascular perfusion rate ratio and the mean pO2 values (R2 > 0.7). The initial rates of increase of Δ[HbO2] and the slope of dynamic pO2 response, d(pO2)/dt, of well-oxygenated voxels in response to hyperoxic challenge were also correlated. These results demonstrate the feasibility of simultaneous measurements using NIRS and MRI. As expected, the rate of pO2 response to oxygen is primarily dependent upon the well perfused rather than poorly perfused vasculature.
A novel anti-CD 37 antibody-drug conjugate with multiple anti-tumor mechanisms for the treatment of B-cell malignancies

The CD37 antigen is a transmembrane protein of the tetraspanin superfamily that is highly expressed on B cells during the pre-B to peripheral mature B-cell stages, but is absent on early progenitor cells or terminally differentiated plasma cells. Although the exact physiological role of CD37 is unclear, it may play a role in immune cell proliferation and influences signaling via the Akt pathway. In normal tissues, CD37 expression is restricted to lymphoid tissues. However, CD37 is highly expressed on malignant B cells in nonHodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL). This expression profile suggests that CD37 represents a promising therapeutic target for B-cell malignancies. Anti-CD20 antibodies such as rituximab and ofatumumab have proven to be effective for treatment of NHL and CLL, either as single agents or in combination therapy, and a number of additional CD20-targeting therapeutic agents are in development. The intrinsic anticancer activities of these antibodies include direct signaling/ proapoptotic activity and immune effector activities such as antibodydependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). However, many patients eventually experience relapse or experience resistance to available treatments, creating a need for additional therapeutic options. To date, a limited number of CD37-directed antibody therapeutic candidates have been evaluated in patients. Radioimmunotherapy with I-MB-1 in patients with NHL who experience relapse resulted in some limited clinical responses, but this agent was not further developed as a therapeutic drug. More recently, a CD37-binding small modular immunopharmaceutical protein advanced into clinical testing as a treatment of B-cell malignancies, and some clinical data have been reported. In addition, an Fc-engineered antibody to CD37 is in early development. Although these initial data suggest that CD37-directed therapies may be effective, there is still a need for agents with improved efficacy. Antibody-drug conjugates (ADCs) have been developed that covalently link cytotoxic agents to tumor-targeting antibodies to enhance their antitumor potency. This approach is designed to allow for specific delivery of cytotoxic compounds to cells expressing the target antigen, through ADC binding, internalization, and intracellular payload release. Emerging clinical data have demonstrated the potential of ADCs to be novel, highly effective targeted cancer therapies. Brentuximab vedotin (Adcetris, SGN-35), an auristatinbased CD30-targeting conjugate, was granted accelerated approval as a treatment of relapsed Hodgkin lymphoma and systemic anaplastic large-cell lymphoma.

Bayesian region merging probability for parametric image models

A novel Bayesian approach to region merging is described. It directly uses statistical image models to determine the probability that the union of two regions is homogeneous, and does not require parameter estimation. This approach is particularly beneficial for cases in which the merging decision is most likely to be incorrect, i.e., when little information is contained in one or both of the regions and when parameter estimates are unreliable. The formulation is applied to the implicit polynomial surface model for range data, and texture models for intensity images. <<ETX>>
"Hypnosis" as a facilitator in behavior therapy.

Abstract It is emphasized that people who enter therapy believing that hypnosis will facilitate their progress often possess a self-fulfilling prophecy that should be utilized in their treatment. Clients who requested hypnosis and received a standard relaxation sequence that substituted the word “hypnosis” for “relaxation” wherever possible, showed more subjective and objective improvements than those who received ordinary relaxation therapy. The main study contained 20 clients treated in a behavior therapy context. 6 additional clients who had not specifically requested either hypnosis or relaxation showed no differences when treated by either or both methods. The differences in outcome are attributed to “expectancy fulfillment. ”
Psychotropic drugs in use today. The role of diazepam in medical practice.

Until the discovery of chlorpromazine in 1952, there were no specific drug treatments in psychiatry, only sedatives and stimulants. The efficacy of chlorpromazine hydrochloride in schizophrenia began a hunt for other specific remedies leading to the discovery of imipramine hydrochloride for depression in 1957, followed by several newer sedatives supposedly specific for neurotic anxiety and called "minor tranquilizers. " These arrived between 1957 and 1965 and included hydroxyzine hydrochloride (Atarax, Vistaril), meprobamate (Equanil, Miltown), and the benzodiazepines (Librium, Valium, and Serax). In addition, combinations of so-called antidepressants and tranquilizers have become available and new or older drugs now are claimed to have dual actions in treating both anxiety and depression. Since these drugs became available, there have been many studies of which drugs should be used in particular conditions. By way of contrast, this review examines what drugs are actually being used and what types of illness they are prescribed to
AA-Maps - Attenuation and Accumulation Maps for Spatio-temporal Event Visualisation

"Some phenomena, such as crimes in a city, fires occurred in a country and road accidents can be interpreted as sets of spatio-temporal events. A spatio-temporal event is described by a geographic location, a time instant and other characterising attributes.The cartographic visualisation of spatio-temporal events remains unresolved, due to the challenges related with portraying multiple dimensions simultaneously: the spatial, the temporal and the semantic (zero or more dimensions) phenomenon's components. In this context, this article presents the Attenuation and Accumulation Maps (AA-Maps). The main idea of this visualisation analytic approach consists in showing in a map, the resulting effect of combining attenuation and accumulation, from a temporal reference of observation, given a spatio-temporal Level of Detail (LoD). Imagine the footprints of people crossing a garden in various directions. They leave different traces that summarize the cumulative effect of the footprints on the grass, which is attenuated as time goes by.AA-Maps support different combinations of attenuation and accumulation functions. In addition, this method also enables analysis with different Levels of Detail (LoD), both spatial and temporal. This allows distinct analytic perspectives of the phenomenon while promoting the search for the most suitable parametrization for its characteristics. "
The Rainbow Scale: A Simple, Validated Online Method to Score the Outcome of Aesthetic Treatments.

Photographs have become an important integral part of documentation in an aesthetic surgery practice, both for medico-legal as well as scientific purposes.1 Only by evaluating pre- and postoperative photographic documentation are we able to evaluate our success and treatment outcomes in an objective way. Several photographic scales have already been developed for this purpose.2-4 However, an easy online system to evaluate aesthetic outcomes in a validated, fast, reliable, and standardized way is still lacking. We have therefore designed what we call the “Rainbow Scale” method based on the Merz Scales (Merz Pharmaceuticals GmbH, Frankfurt, Germany) (Figure 1). 2 In this online system, 6 photographs are presented in a block of two rows of 3 photographs. The photograph of the patient to be evaluated is located in the central position of the lower row. Other photographs show the five grades of severity of the area to be evaluated, with the lowest score left of the photograph to be evaluated, the second score on the upper left side, etc. until the highest score on the lower right side of the photograph. The different scores are thus presented around the patient in a rainbow fashion. …
Index Reduction in Differential-Algebraic Equations Using Dummy Derivatives

A new index reduction algorithm for DAEs is developed. In the usual manner, parts of the DAE are differentiated analytically and appended to the original system. For each additional equation, a derivative is selected to be replaced by a new algebraic variable called a dummy derivative. The resulting augmented system is at most index 1, but no longer overdetermined. The dummy derivatives are not subject to discretization; their purpose is to annihilate part of the dynamics in the DAE, leaving only what corresponds to the dynamics of a state-space form. No constraint stabilization is necessary in the subsequent numerical treatment. Numerical tests indicate that the method yields results with an accuracy comparable to that obtained for the corresponding state-space ODE.
Excitation of dipole oscillons in a dusty plasma containing elongated dust rods

The dispersion properties and excitation mechanisms of `dipole oscillons' in a dusty plasma containing charged elongated rod-like dust grains are investigated in the presence of streaming plasma particles for cases without and with an external static magnetic field. In a magnetized dusty plasma, a new `oscillon-ion lower-hybrid' mode is found, which can be excited by the equilibrium energy of cross-field drifting ions.
By how much and how quickly does reduction in serum cholesterol concentration lower risk of ischaemic heart disease?

Abstract Objective: To estimate by how much and how quickly a given reduction in serum cholesterol concentration will reduce the risk of ischaemic heart disease. Design: Data on the incidence of ischaemic heart disease and serum cholesterol concentration were analysed from 10 prospective (cohort) studies, three international studies in different communities, and 28 randomised controlled trials (with mortality data analysed according to allocated treatment to ensure the avoidance of bias). Main outcome measure - Decrease in incidence of ischaemic heart disease or mortality for a 0.6 mmol/l (about 10%) decrease in serum cholesterol concentration. Results: For men results from the cohort studies showed that a decrease of serum cholesterol concentration of 0.6 mmol/l (about 10%) was associated with a decrease in incidence of ischaemic heart disease of 54% at age 40 years, 39% at age 50, 27% at 60, 20% at 70, and 19% at 80. The combined estimate from the three international studies (for ages 55-64 years) was 38% (95% confidence interval 33% to 42%), somewhat greater than the cohort study estimate of 27%. The reductions in incidence of ischaemic heart disease in the randomised trials (for ages 55-64 years) were 7% (0 to 14%) in the first two years, 22% (15% to 28%) from 2.1-5 years, and 25% (15% to 35%) after five years, the last estimate being lose to the estimate of 27% for the long term reduction from the cohort studies. The data for women are limited but indicate a similar effect. Conclusions - The results from the cohort studies, international comparisons, and clinical trials are remarkably consistent. The cohort studies, based on half a million men and 18 000 ischaemic heart disease events, estimate that a long term reduction in serum cholesterol concentration of 0.6 mmol/l (10%), which can be achieved by moderate dietary change,lowers the risk of ischaemic heart disease by 50% at age 40, falling to 20% at age 70. The randomised trials, based on 45 000 men and 4000 ischaemic heart disease events show that the full effect of the reduction in risk is achieved by five years.
Comparison and evaluation of the PLL techniques for the design of the grid-connected inverter systems

The knowledge of the phase, amplitude and frequency of the utility voltage is a fundamental aspect for the design of the grid-connected inverter systems. In this paper are presented the basic features of the PLL technique. A particular attention is dedicated to the Synchronous Reference Frame-PLL scheme. About the generation of the orthogonal voltages system an evaluation of the most employed techniques is shown: Transport Delay, Inverse Park Transformation, Hilbert Transformation, Second Order Generalized Integrators (SOGI). Moreover some problems in filtering are treated. The internal filtering - due to the PD structure - and the external filtering - due to the harmonics presence in the grid voltage. In both the cases the most employed solutions are shown. For the internal filtering: Low Pass Filter, Resonant Filter, Moving Average Filter, Repetitive Controller. For the external filtering two alternative schemes are presented: the Dual SOGI-PLL and the Enanched-PLL (EPLL).
