Chemical Treatment of Petroleum Wastewater and its Effect on the Corrosion Behavior of Steel Pipelines in Sewage Networks

The sources of wastewater from municipal and different industries act as a substantial pressure on the surrounding environment, so the waste management is ordinarily required before drainage. The environmental protection agency added specific and limited levels for discharging the pollutants into the municipal networks or into the sea. The treatment process of industrial wastewater became must to remove the contaminants or pollutants, which produced from the production procedure to a maximum, which does not negatively affect the environment. Chemical coagulation process is the highest important technique for industrial wastewater treatment because of its efficiency to minimize the contaminants in wastewater. The coagulants for higher removal of the contaminants and have a low cost is the most important choice of wastewater treatment. In this paper, chemical coagulation process for a petroleum wastewater sample by using ferric chloride, aluminum sulfate and polyacrylamide separately or as a mixture as well as the corrosion behavior of untreated and treated wastewater samples have been investigated. According to the obtained results the best formula, which gives the best result in removal of the organic and inorganic wastes as well as the best corrosion results is the mixture of aluminum sulfate and polyacrylamide. This formula have double functions, decreasing the total dissolved salts of about 21.11% and decreasing the COD and BOD content with about 47.95% and 53.57% respectively. These results proved that this formula is the best in corrosion behavior on mild steel pipelines.
STUDY OF EFFECTS OF THE SHORT TIME FOURIER TRANSFORM CONFIGURATION ON EEG SPECTRAL ESTIMATES

EEG signals recorded from scalp contain useful information about the activity of a large number of neurons. Signal processing is needed to extract this information from the EEG signal. Here we study the effects of configurations of Short Time Fourier Transform (STFT) to determine how the parameters of STFT affect spectral estimations of the mean and relative power in beta and gamma frequency bands of the EEG signal. A statistic analysis was performed showing the effects of several window types and window lengths. The estimation of power in a specific frequency band is affected by the configuration of the STFT.
Development of a biosensor based on laser-fabricatedpolymer microcantilevers

We develop high-sensitivity biosensors based on microcantilevers. The polymer microcantilevers are fabricated by fast and cost-effective laser machining processes. Polymer film is selected because it gives better sensitivity of deflection measurements than silicon due to its lower Young’s modulus and also its cost is much lower. We demonstrate using these polymer microcantilevers for biological molecular analysis in a DNA hybridization experiment. It is shown that our biosensor is capable of detecting 12 base oligonucleotide with concentrations as low as 0. 01μM.
Incorporation of fluorescent enzyme substrates in agarose gel for in situ zymography.

The currently available methods for the detection of proteases in tissue sections are characterized by limited substrate specificity and low sensitivity and are also cumbersome. We have developed a novel in situ zymography method that uses a synthetic substrate conjugated to a fluorescent tag for detection of proteases in tissue sections. In the presence of active enzyme, the fluorescent tag is cleaved off from the substrate peptide chain resulting in an approximately 100-fold increase in the fluorescent signal. In order to minimize the diffusion of the fluorescent tag, the substrate is incorporated into 1% agarose prior to overlaying onto the tissue section. This method retains the morphological details of the tissue section, is highly sensitive and specific for the designated peptide sequence, and provides information regarding the functional status of the enzyme. Thus, this method could be used for detection and monitoring of enzymatic activity in tissue sections for a variety of applications.
Dissociation between cognitive and affective empathy in youth with Asperger Syndrome

Autism spectrum conditions, among them Asperger Syndrome (AS), are generally described as entailing deficits in “cognitive empathy” or “theory of mind”. People with AS tend to have difficulties recognizing emotions, although the extent of these difficulties is still unclear. This study aimed to assess empathic profile in youth with AS (N = 38) and controls matched on age, sex and IQ. The study aimed to test if a dissociation between cognitive and affective empathy exists in AS. The study also aimed to explore emotion recognition in people with AS, and how it relates to emotional valence (positive, negative, and neutral emotions). The AS group scored lower than controls on cognitive empathy but scored within the average range on affective empathy. A deficit in emotion recognition was found in the AS group for positive emotions. These results confirm earlier findings in cognitive empathy and provide new insight about emotion recognition abilities in this population.
RESEARCH ARTICLE Integrative Cardiovascular Physiology and Pathophysiology Short-term regular aerobic exercise reduces oxidative stress produced by acute high intraluminal pressure in the adipose microvasculature

Short-term regular aerobic exercise reduces oxidative stress produced by acute high intraluminal pressure in the adipose microvasculature. Am J Physiol Heart Circ Physiol 2017. blood pressure has been shown to elicit impaired dilation in the vasculature. The purpose of this investigation was to elucidate the mechanisms through which high pressure may elicit vascular dysfunction and determine the mechanisms through which regular aerobic exercise protects Three control male mice used for experiments determine if ment, 100 U/ml penicillin, and 100 (cid:4) g/ml streptomycin at 37°C in a humidiﬁed incubator (5% CO 2 ). Shear stress experiments. HAMECs were grown to 80–90% conﬂuence. High physiological laminar shear stress (20 dyn/cm 2 for 24 h) was generated using a previously described modiﬁed cone and plate design (3, 39). This level of shear stress has been used in several exercise mimetic models (14, 26). The cone used in these studies is designed to ﬁt into a 20 (cid:10) 100-mm tissue culture dish. Magnetism to rotate the cone is provided by magnets within a modiﬁed Thermo Scientiﬁc Super-Nuova multiplace stirrer (Thermo Fisher Scientiﬁc). The angle between the cone and plate is negligible (~0.5°), thus facilitating uniform ﬂow over all HAMECs on the culture dish.

The Dependence of the Yersinia pestis Capsule on Pathogenesis Is Influenced by the Mouse Background

ABSTRACT Yersinia pestis is a highly pathogenic Gram-negative organism and the causative agent of bubonic and pneumonic plague. Y. pestis is capable of causing major epidemics; thus, there is a need for vaccine targets and a greater understanding of the role of these targets in pathogenesis. Two prime Y. pestis vaccine candidates are the usher-chaperone fimbriae Psa and Caf. Herein we report that Y. pestis requires, in a nonredundant manner, both PsaA and Caf1 to achieve its full pathogenic ability in both pneumonic and bubonic plague in C57BL/6J mice. Deletion of psaA leads to a decrease in the organ bacterial burden and to a significant increase in the 50% lethal dose (LD50) after subcutaneous infection. Deletion of caf1 also leads to a significant decrease in the organ bacterial burden but more importantly leads to a significantly greater increase in the LD50 than was observed for the ΔpsaA mutant strain after subcutaneous infection of C57BL/6J mice. Furthermore, the degree of attenuation of the Δcaf1 mutant strain is mouse background dependent, as the Δcaf1 mutant strain was attenuated to a lesser degree in BALB/cJ mice by the subcutaneous route than in C57BL/6J mice. This observation that the degree of requirement for Caf1 is dependent on the mouse background indicates that the virulence of Y. pestis is dependent on the genetic makeup of its host and provides further support for the hypothesis that PsaA and Caf1 have different targets.
Assessing Loss of Biodiversity in Europe Through Remote Sensing: The Necessity of New Methodologies

There is a global consensus on the idea of the present loss of biodiversity is intimately linked with human development, and that the conservation and sustainable use of present biological diversity is paramount to current and future generations of all life on Earth (Duro et al. 2007). The United Nation Convention on Biological Diversity (CBD, http://www. biodiv.org, last accessed May 2011) lays down that countries are responsible for conserving their biological diversity and for using their biological resources in a sustainable manner. It expands until 2020 with the global Strategy Plan for Biodiversity 2011-2020 and the Aichi biodiversity targets (http://www.cbd.int/2011-2020, last accessed May 2011) to promote effective implementation of the CDB and to stem biodiversity loss by 2020. It compels the contracting countries to develop scientific and technical capacities to provide the appropriate measures in order to prevent and halt the pace of biodiversity loss all around the world. It was during 90s and 2000s when scientific community became conscious that habitat destruction is the most prominent driver of biodiversity loss (Dirzo and Raven 2003)and together with degradation and fragmentation represent the most important factors leading to worldwide species decline and extinction (Chhabra et al. 2006; Soule and Terborgh 1999). To improve the current conservation efforts and draw new strategies around the commitments under the CBD, it is crucial that our progress is monitored (Pereira and Cooper 2006). Biodiversity monitoring should be focused on trends in the abundance and distribution of populations and habitat extent (Balmford et al. 2005) and be carried out at different scales, regional and global and even local (Pereira and Cooper 2006). There are several biophysical features influence species distributions, population sizes and ranges like land cover, primary productivity, temporal vegetation dynamics, disturbance events or climate (Hansen et al. 2004). All of them could be used as biophysical predictors of biodiversity at different scales. Remote sensing has been shown to be effective in some extent to measure and mapping those indicators and it has become a powerful tool for ecological studies because it allows monitoring over significant areas (Kerr and Ostrovsky 2003).
Word line pulsing technique for stability fault detection in SRAM cells

Stability testing of SRAMs has been time consuming. This paper presents a new programmable DFT technique for detection of stability and data retention faults in SRAM cells. The proposed technique offers extended flexibility in setting the weak overwrite test stress, which allows to track process changes without time-consuming post-silicon design iterations. Moreover, it does not introduce extra circuitry in the SRAM array and surpasses the data retention test in test time and detection capability
In vivo tracking of human adipose-derived stem cells labeled with ferumoxytol in rats with middle cerebral artery occlusion by magnetic resonance imaging

Ferumoxytol, an iron replacement product, is a new type of superparamagnetic iron oxide approved by the US Food and Drug Administration. Herein, we assessed the feasibility of tracking transplanted human adipose-derived stem cells labeled with ferumoxytol in middle cerebral artery occlusion-injured rats by 3.0 T MRI in vivo. 1 × 10 4 human adipose-derived stem cells labeled with ferumoxytol-heparin-protamine were transplanted into the brains of rats with middle cerebral artery occlusion. Neurologic impairment was scored at 1, 7, 14, and 28 days after transplantation. T2-weighted imaging and enhanced susceptibility-weighted angiography were used to observe transplanted cells. Results of imaging tests were compared with results of Prussian blue staining. The modified neurologic impairment scores were significantly lower in rats transplanted with cells at all time points except 1 day post-transplantation compared with rats without transplantation. Regions with hypointense signals on T2-weighted and enhanced susceptibility-weighted angiography images corresponded with areas stained by Prussian blue, suggesting the presence of superparamagnetic iron oxide particles within the engrafted cells. Enhanced susceptibility-weighted angiography image exhibited better sensitivity and contrast in tracing ferumoxytol-heparin-protamine-labeled human adipose-derived stem cells compared with T2-weighted imaging in routine MRI.
Compressed Path Databases with Ordered Wildcard Substitutions

Compressed path databases (CPDs) are a state-of-the-art approach to path planning, a core AI problem. In the Grid-based Path Planning Competition, the CPD-based SRC path planning system was the fastest competitor with respect to both computing full optimal paths and computing the first moves of an optimal path. However, on large maps, CPDs can require a significant amount of memory, which can be a serious practical bottleneck. We present an approach that significantly reduces the size of a CPD. Our approach replaces part of the data encoded in a CPD with wildcards ("don’t care" symbols), maintaining the ability to compute optimal paths for all pairs of nodes of an undirected graph. We show that using wildcards in a way that maximizes the memory savings is NP-hard. We consider heuristics that achieve a good performance in practice. We implement our ideas on top of SRC and provide a detailed empirical analysis. Average memory savings can reach a factor of 2. Our first-k-moves lag (i.e., the time before knowing the first k optimal forward moves) increases, but it can be kept within competitive values. The speed of computing full optimal paths improves slightly.
Dedicated breast CT: fibroglandular volume measurements in a diagnostic population.

PURPOSE To determine the mean and range of volumetric glandular fraction (VGF) of the breast in a diagnostic population using a high-resolution flat-panel cone-beam dedicated breast CT system. This information is important for Monte Carlo-based estimation of normalized glandular dose coefficients and for investigating the dependence of VGF on breast dimensions, race, and pathology. METHODS Image data from a clinical trial investigating the role of dedicated breast CT that enrolled 150 women were retrospectively analyzed to determine the VGF. The study was conducted in adherence to a protocol approved by the institutional human subjects review boards and written informed consent was obtained from all study participants. All participants in the study were assigned BI-RADS(®) 4 or 5 as per the American College of Radiology assessment categories after standard diagnostic work-up and underwent dedicated breast CT exam prior to biopsy. A Gaussian-kernel based fuzzy c-means algorithm was used to partition the breast CT images into adipose and fibroglandular tissue after segmenting the skin. Upon determination of the accuracy of the algorithm with a phantom, it was applied to 137 breast CT volumes from 136 women. VGF was determined for each breast and the mean and range were determined. Pathology results with classification as benign, malignant, and hyperplasia were available for 132 women, and were used to investigate if the distributions of VGF varied with pathology. RESULTS The algorithm was accurate to within ±1.9% in determining the volume of an irregular shaped phantom. The study mean (± inter-breast SD) for the VGF was 0.172 ± 0.142 (range: 0.012-0.719). VGF was found to be negatively correlated with age, breast dimensions (chest-wall to nipple length, pectoralis to nipple length, and effective diameter at chest-wall), and total breast volume, and positively correlated with fibroglandular volume. Based on pathology, pairwise statistical analysis (Mann-Whitney test) indicated that at the 0.05 significance level, there was no significant difference in distributions of VGF without adjustment for age between malignant and nonmalignant breasts (p = 0.41). Pairwise comparisons of the distributions of VGF in increasing order of mammographic breast density indicated all comparisons were statistically significant (p < 0.002). CONCLUSIONS This study used a different clinical prototype breast CT system than that in previous studies to image subjects from a different geographical region, and used a different algorithm for analysis of image data. The mean VGF estimated from this study is within the range reported in previous studies, indicating that the choice of 50% glandular weight fraction to represent an average breast for Monte Carlo-based estimation of normalized glandular dose coefficients in mammography needs revising. In the study, the distributions of VGF did not differ significantly with pathology.
The trade-off between liberalisation policy and financial crises dynamics

In this paper, we attempt to check the extent to which a quick and a rushed liberalisation process is a determining and an explanatory factor of financial crises. With reference to the state space model and Kalman filter technique, we were able to elaborate a new measure of financial openness for the South East Asian countries. This measure is first used to raise the financial openness pace already ill-adapted by these countries during the 1997 crisis. Second, we created a measure of financial instability during the (1990-2008) period. The results led us to the conclusion that a rapid liberalisation process may be a crises-provoking factor. Ten years later, the international financial sector has been hit by a major financial crisis. Some southern Mediterranean countries have been relatively spared the ordeal. Applying these measures on the Tunisia context period, we reached the conclusion that a moderately-paced liberalisation process is a way of avoiding devastating financial situations.
Organophosphate Insecticide Chlorfenvinphos Affects Superoxide Dismutase , Catalase and Malondialdehyde in Rat Liver

The aim of this paper was to study the activity of liver superoxide dismutase and catalase and the concentration of liver malondialdehyde in rats intoxicated with chlorfenvinphos, an organophosphate widely used as an insecticide. The study was carried out on male Wistar rats weighing 180-230 g. The rats were divided into two groups: examined receiving oil solution of chlorfenvinphos in doses of 0.5 LD50, and 0.1 LD50 and control group receiving oil. The activity of superoxide dismutase (SOD), catalase (CAT) and concentration of malondialdehyde (MDA) were determined after 1, 24 and 48 hours of intoxication. We observed an increase in the liver activity of SOD in further period of intoxication with chlorfenvinphos in both doses and a decrease of liver SOD activity in the rats intoxicated with the higher dose. The CAT activity in liver of the treated rats increased at the 1st hour of experiment with a dose of 0.5 LD50 and at the 1st hour and the 24th hour after intoxication with a dose 0.1 LD50. Hepatic concentration of MDA showed a decrease at the 24th hour of intoxication with chlorfenvinphos and an increase at the 48th hour of intoxication with the higher dose and returned to control value for the rats intoxicated with the lower dose. SOD and CAT play a major role in the maintaince of the physiological level of reactive form of oxygen. When reactive oxygen species generation exceeds capability of redox degrading systems, MDA levels in-
Effects of high-amount–high-intensity exercise on in vivo platelet activation: Modulation by lipid peroxidation and AGE/RAGE axis

Summary Physical activity is associated with cardiovascular risk reduction, but the effects of exercise on platelet activation remain controversial. We investigated the effects of regular high-amount, high intensity aerobic exercise on in vivo thromboxane (TX)-dependent platelet activation and plasma levels of platelet-derived proteins, CD40L and P-selectin, and whether platelet variables changes may be related to changes in high-density lipoprotein (HDL) and in the extent of oxidative stress and oxidative stress-related inflammation, as reflected by urinary isoprostane excretion and endogenous soluble receptor for advanced glycation end-products (esRAGE), respectively. Urinary excretion of 11-dehydro-TXB2 and 8-iso-prostaglandin (PG)F2α and plasma levels of P-selectin, CD40L and esRAGE were measured before and after a eight-week standardised aerobic high-amount–high-intensity training program in 22 sedentary subjects with low-to-intermediate risk. Exercise training had a clear beneficial effect on HDL cholesterol (+10%, p=0.027) and triglyceride (-27%, p=0.008) concentration. In addition, a significant (p<0.0001) decrease in urinary 11-dehydro-TXB2 (26%), 8-iso-PGF2α (21 %), plasma P-selectin (27%), CD40L (35%) and a 61% increase in esRAGE were observed. Multiple regression analysis revealed that urinary 8-iso-PGF2α [beta=0.33, SEM=0.116, p=0.027] and esRAGE (beta=-0.30, SEM=31.3, p=0.046) were the only significant predictors of urinary 11-dehydro-TXB2 excretion rate over the training period. In conclusion, regular high-amount–high-intensity exercise training has broad beneficial effects on platelet activation markers, paralleled and possibly associated with changes in the lipoprotein profile and in markers of lipid peroxidation and AGE/RAGE axis. Our findings may help explaining why a similar amount of exercise exerts significant benefits in preventing cardiovascular events.

Peptic ulcer in India and its aetiology

SYNOPSIS A study of the incidence of peptic ulcer amongst railway workers in various parts of India has shown that ulcer is more common in wet and humid areas than in the dry and arid regions. This observation is also supported by the ulcer incidence reported in other studies from India, Africa, and the West. Saliva appears to have an important role in the prevention of ulcer, because of its rich content of blood group antigens. There may be unrecognized factors in the saliva which may be ulcerogenic and others which prevent ulcer. Parasympathetic overaction also appears to contribute to ulcer formation due to its effect on salivation, sexual activity, and stress and strain.
