Effect of Styrene Butadiene Rubber Latex on Mechanical Properties of Eco Concrete: Limestone Powder Concrete

To make concrete a truly green material, viable cement substitutes are available. This experimental investigation is performed to study the effect of using limestone powder (LSP) and styrene butadiene rubber (SBR) latex in the concrete mix. In this work, a concrete with 1:1.8:3 cementitious material:sand:gravel and water/cement ratio w/c of 0.5 is produced. First, LSP is used with 0, 5, 10, 15, and 20% replacements by weight of cements. The fineness of the LSP is measured using sieve No. 200 and showed about 30% pass. Second, and to improve the matrix of concrete due to the dilution effect, four ratios of SBR latex (0, 5, 10, and 15%) are added by weight of cements to the mix for each LSP ratio. Compressive strength at ages of 3, 7, 14, 28, and 90 days is tested for the concrete specimens mixed with LSP only to examine its effect on concrete strength’s development with time, whereas strengths are recorded at the age of 28 days for the other concretes. Three prisms were cast for each ratio and tested at 28 days. The results show general improvements in terms of compressive and flexural strengths

Effects of Parallel Processing Implementation on Balanced Load-Division Depending on Distributed Memory Systems

Complex problems need long time to be solved, with low efficiency and performance. Therefore, to overcome these drawbacks, the studies went toward the approaches of breaking the problem into independent parts, and treating each part individually in the way that each processing element can execute its part of the problem simultaneously with the others.Parallel processors are computer systems that consist of multiple processing units connected via some interconnection network and the software needed to make the processing units work together. Parallel processing is divided into three types; Shared, Distributed and Hybrid memory systems.In this paper, distributed memory systems addressed depending on client/servers principles, the network can contain any number of nodes; one of them is a client and the others are servers. The algorithms used here are capable of calculating the (Started, Terminated, Consumed -CPU and Total Execution- times and CPU usage) of servers and the Client's -CPU and total execution- times. This work addresses an improved approach for problem subdivision in balanced form and design flexible algorithms to communicate efficiently between client-side and servers-side in the way to overcome the problems of hardware networking components and message passing problems. We addressed Matrix-Algebra case-study to display the effect of balance loaddivision for this approach. The obtained results are checked and monitored by special programming-checkingsubroutines through many testing-iterations and proved a high degree of accuracy. All of these algorithms implemented using Java Languag

Concomitant Case of Primary Biliary Cirrhosis and Autoimmune Hemolityc Anemia Responding to Corticosteroid and Ursodeoxycholic Acid in Young Woman

Primary biliary cirrhosis (PBC) is an autoimmune liver disease of unknown etiology and is characterized by chronic progressive cholestasis with destruction of the small intrahepatic bile ducts and associated most commonly with antimitochondrial antibodies. PBC is most common in women and is often associated with other autoimmune disease such as autoimmune hemolityc anemia (AIHA), rheumatoid arthritis, thyroiditis, and systemic lupus eritomatosus.            We report one case, a 20 years old woman with AIHA have been treated by corticosteroid since last year and she came to the outpatient department (OPD) with fatique and jaundice. The result of laboratory were haemoglobin 8.7 mg/dL, white blood cell 8700 mg/dL, coomb test +2, total bilirubin 33.2 mg/dL, direct bilirubin 29.3 mg/dL, γGT: 297 mg/dL and alkalyphospatase: 158 mg/dL. The result of Abdominal CT scan showed the size of liver and spleen increased and normal common bile duct (CBD). The result of ANA test, anti-nuclear (ANA) and antimitochondrial M2 (AMA M2) antibodies were positive. From the physical examination, laboratory and CT scan Abdomen; the diagnose of this patient was AIHA with PBC.            After treatment with corticosteroid (prednison 1mg/kg/day) and ursodeoxicholic acid (UDCA) for several weeks, the clinical manifestation of PBC such as jaundice getting better (the laboratory result: total bilirubin 2.7 mg/dL, direct bilirubin 1.5 mg/dL, gamma GT 80 mg/dL)

A Quantitative Approach to Estimate the Damage Inflicted by Traffic Pollution on Historic Buildings in Al-Salt City, Jordan

Traffic in the city of Al-Salt is not only putting pedestrians at risk and threatening the health of citizens, it is also damaging the town's historic buildings. Most stone buildings in the heritage-rich city are suffering adverse effects from vehicle-related pollution. This effect is highly visible soiling and discoloration from deposited carbon particles in the form of fine soot on most buildings. The level and progress of the damage depends on the geology of the stone and the proximity of the structure from traffic congestion. The accumulation of soot leads to the buildup of black sulfate (gypsum) skins on the limestone facade which causes the sound stone behind it to disintegrate. It is vital to the well-being of this historic treasure that the volume of the city traffic must be reduced and traffic flow improved. The main objective of this study is to qualitatively and quantitatively assess the damage caused to buildings of historical and cultural value by traffic pollution. Age of vehicles running on city’s streets and the rate of their emissions are quantified and analyzed. Several field investigations and laboratory tests were conducted to identify the chemical relations between pollutants and stone decay on these buildings. Keywords: Traffic pollution, tailpipe emission, vehicular emission, historic buildings, limeston

A Multimodality Hybrid Gamma-Optical Camera for Intraoperative Imaging

The development of low profile gamma-ray detectors has encouraged the production of small field of view (SFOV) hand-held imaging devices for use at the patient bedside and in operating theatres. Early development of these SFOV cameras was focussed on a single modality-gamma ray imaging. Recently, a hybrid system-gamma plus optical imaging-has been developed. This combination of optical and gamma cameras enables high spatial resolution multi-modal imaging, giving a superimposed scintigraphic and optical image. Hybrid imaging offers new possibilities for assisting clinicians and surgeons in localising the site of uptake in procedures such as sentinel node detection. The hybrid camera concept can be extended to a multimodal detector design which can offer stereoscopic images, depth estimation of gamma-emitting sources, and simultaneous gamma and fluorescence imaging. Recent improvements to the hybrid camera have been used to produce dual-modality images in both laboratory simulations and in the clinic. Hybrid imaging of a patient who underwent thyroid scintigraphy is reported. In addition, we present data which shows that the hybrid camera concept can be extended to estimate the position and depth of radionuclide distribution within an object and also report the first combined gamma and Near-Infrared (NIR) fluorescence images.Peer-reviewedPublisher Versio

Recent advances in fiber-shaped and planar-shaped textile solar cells

During the last few years, textile solar cells with planar and fiber-shaped configurations have attracted enormous research interest. These flexible-type solar cells have a huge potential applicability in self-powered and battery-less electronics, which will impact many sectors, and particularly the Internet of Things. Textile solar cells are lightweight, super-flexible, formable, and foldable. Thus, they could be ideal power-harvester alternatives to common flexible solar cells required in smart textiles, electronic textiles, and wearable electronic devices. This review presents a brief overview on fiber-shaped and planar-shaped solar cells, and it introduces the most recent research reports on the different types of textile solar cells, including details on their fabrication techniques. It also addresses the current challenges and limitations of their technology development, and the encountered issues for their future application and integration in novel devices

Hemichannel-mediated and pH-based feedback from horizontal cells to cones in the vertebrate retina

Background: Recent studies designed to identify the mechanism by which retinal horizontal cells communicate with cones have implicated two processes. According to one account, horizontal cell hyperpolarization induces an increase in pH withinthe synaptic cleft that activates the calcium current (Ca2+-current) in cones, enhancing transmitter release. An alternative account suggests that horizontal cell hyperpolarization increases the Ca2+-current to promote transmitter release through ahemichannel-mediated ephaptic mechanism.Methodology/Principal Findings: To distinguish between these mechanisms, we interfered with the pH regulating systems in the retina and studied the effects on the feedback responses of cones and horizontal cells. We found that the pH buffers HEPES and Tris partially inhibit feedback responses in cones and horizontal cells and lead to intracellular acidification ofneurons. Application of 25 mM acetate, which does not change the extracellular pH buffer capacity, does lead to both intracellular acidification and inhibition of feedback. Because intracellular acidification is known to inhibit hemichannels, the key experiment used to test the pH hypothesis, i.e. increasing the extracellular pH buffer capacity, does not discriminatebetween a pH-based feedback system and a hemichannel-mediated feedback system. To test the pH hypothesis in a manner independent of artificial pH-buffer systems, we studied the effect of interfering with the endogenous pH buffer, the bicarbonate/carbonic anhydrase system. Inhibition of carbonic anhydrase allowed for large changes in pH in the synapticcleft of bipolar cell terminals and cone terminals, but the predicted enhancement of the cone feedback responses, according to the pH-hypothesis, was not observed. These experiments thus failed to support a proton mediated feedback mechanism. The alternative hypothesis, the hemichannel-mediated ephaptic feedback mechanism, was therefore studied experimentally, and its feasibility was buttressed by means of a quantitative computer model of the cone/horizontal cellsynapse.Conclusion: We conclude that the data presented in this paper offers further support for physiologically relevant ephaptic interactions in the retina
