In vitro effect of head position on the accuracy of linear measurements of implants at the sites of maxillary lateral incisors and first molars on cone- beam computed tomography scans

Objectives: This study assessed the effect of head position on the accuracy of linear measurements of implants at the sites of maxillary lateral incisors and first molars using cone-beam computed tomography (CBCT). Materials and Methods: This in vitro study evaluated seven dry human skulls. Four titanium implants were bilaterally placed at the sites of maxillary lateral incisors and first molars. CBCT scans were obtained following tipping of the skulls by +20°, +10°, 0°, -10°, and -20°. The change in height of implants visualized on each CBCT scan was calculated compared with their actual height measured by a caliper. Data were analyzed using ANCOVA and Wilcoxon test. Results: On CBCT scans, the height of posterior implants in +20° (P=0.032) and +10° (P=0.017) tipping positions was significantly higher than the actual value; but no significant difference was noted in other positions. The mean height of anterior implants in the right side on CBCT scans was significantly higher than the left side in -10° (P=0.025) tipping position. The mean implant height in the right side was significantly lower than the left side in +10° (P=0.017) and 0° (P=0.041) tipping positions. In the posterior region, the mean implant height in the right side was significantly lower than the left side in -20° (P=0.025) and +10° (P=0.017) tipping positions. Conclusion: Backward tipping of the head by 20° and 10° affects the implant height on CBCT scans. The possibility of change in linear measurements in the posterior implants is higher than in the anterior implants.
Early fluid aspiration among cesarean section scar deficiency reduces cancellation rate and increase the clinical pregnancy rate among patients undergoing frozen embryo transfer

Fifty Years of Noise Modeling and Mitigation in Power-Line Communications

Building on the ubiquity of electric power infrastructure, power line communications (PLC) has been successfully used in diverse application scenarios, including the smart grid and in-home broadband communications systems as well as industrial and home automation. However, the power line channel exhibits deleterious properties, one of which is its hostile noise environment. This article aims for providing a review of noise modeling and mitigation techniques in PLC. Specifically, a comprehensive review of representative noise models developed over the past fifty years is presented, including both the empirical models based on measurement campaigns and simplified mathematical models. Following this, we provide an extensive survey of the suite of noise mitigation schemes, categorizing them into mitigation at the transmitter as well as parametric and non-parametric techniques employed at the receiver. Furthermore, since the accuracy of channel estimation in PLC is affected by noise, we review the literature of joint noise mitigation and channel estimation solutions. Finally, a number of directions are outlined for future research on both noise modeling and mitigation in PLC.
ENHANCEMENT OF THIRD-ORDER OPTICAL NONLINEARITIES IN 72GeS2-18Ga2S3-10CdS GLASSES BY Ag ION IMPLANTATION

The third-order nonlinearity of 72GeS2-18Ga2S3-10CdS chalcogenide glass implanted by Ag ions was studied. The doses for implantation were ranging from 1×10 16 to 2×10 17 ions/cm 2 and Ag nanoparticles were observed by the AFM measurements. The third-order nonlinear optical property  (3) was measured by the femtosecond Z-scan technique and showed the maximum value of 7.58×10 -11 esu. The results indicated that the  (3) enhancement of implanted samples was due to the formation of Ag nanoparticles. The relation between the implanted dose and the third order nonlinearity was related to the enhancement of local field inside the particles and the interaction between Ag nanoparticles, which will be useful in fabricating optical devices by controlling the implanted doses to controlling the optical nonlinearity in glasses.
DEPOSITION OF WIDE SIZE DISTRIBUTION, BINGHAM PLASTIC SLURRIES IN TURBULENT PIPE FLOW

At the 17 T&S conference in Delft, the author (Thomas, 2015), presented a Modified Wilson & Judge (MW&J) method for predicting the deposit velocity of mono-sized particles in Newtonian fluids. The present paper extends consideration of the MW&J method to wide size distribution mineral slurries, which have Bingham plastic properties. For these slurries, turbulent flow deposition can occur due to three processes: heterogeneous deposition as predicted by the MW&J method; viscous sub-layer deposition which occurs when particles are smaller than the viscous sub-layer; and transition deposition where deposition is due to transition to laminar flow. The three types of deposition are investigated primarily by comparing predictions with the test loop data of Goosen & Paterson (2014). The Goosen & Paterson data applies to a wide size distribution gold tailings with Bingham plastic properties. The paper discusses the relevant viscosity to use in the MW&J and the viscous sub-layer predictions, and two options are compared. The first option simply uses the plastic viscosity and the second option uses the effective viscosity which varies with velocity. The -75 m portion is assumed to represent a homogeneous vehicle slurry, and the +75 m portion is assumed represented by the 110 m, d50 size, of the +75 m portion. At very high concentrations, and especially in the two smaller pipe diameters, laminar flow without deposition was observed in the Goosen & Paterson data. Laminar flow in test loops and in longer pipelines is discussed.
A tale of two medicinal plants: A comparative study of medicinal bioactivity of homoeopathic tinctures of Coleus aromaticus and Coleus zeylanicus

A comparative study of medically useful biological activites of homoeopathic tinctures of two closely related medicinal plants, namely Coleus aromaticus and Coleus zeylanicus was conducted. It was revealed that the tincture of C. zeylanicus exhibited potent anti-bacterial activity against gram negative Klebsiella pneumoniae, E.coli and Enterococcus faecalis compared to C aromaticus which exhibited activity against S. aureus alone. Both plant tinctures exhibited similar anti-oxidant activity. LOX inhibition assay proved that both plant tinctures inhibited the enzyme and C. zeylanicus was more inhibitory. C. zeylanicus showed 54.7% inhibition and C aromaticus, 13.5% when used in the same concentration. The results of inhibition of denaturation of protein indicated that C. zeylanicus was more effective as an anti-inflammatory agent compared to C. aromaticus. The extent of inhibition was 68% and 55% for the two plant tinctures respectively. It was therefore concluded that C. zeylanicus was more useful medicinally out of the two plants.
Mathematical Analysis of Effects of Surface Roughness on Steady Performance of Hydrostatic Thrust Bearings Lubricated with Rabinowitsch Type Fluids

The objective of present theoretical analysis is to study the combined influence of surface roughness and lubricant inertia on the steady performance of stepped circular hydrostatic thrust bearings lubricated with nonNewtonian Rabinowitsch type fluids. To take the effects of surface roughness into account, Christensen theory of rough surface has been adopted. Solution for momentum equation has been derived by means of average inertia approach. Analytic expressions for film pressure have been established for radial and circumferential roughness patterns. Results for film pressure, load carrying capacity of bearing and lubricant flow rate has been plotted and analyzed on the basis of numerical results. Due to surface roughness, significant variations in these properties have been observed.
Understanding Ecosystem Complexity via Application of a Process-Based State Space rather than a Potential Surface

Ecosystems are complex objects, simultaneously combining biotic, abiotic, and human components and processes. Ecologists still struggle to understand ecosystems, and one main method for achieving an understanding consists in computing potential surfaces based on physical dynamical systems. We argue in this conceptual paper that the foundations of this analogy between physical and ecological systems are inappropriate and aim to propose a new method that better reflects the properties of ecosystems, especially complex, historical nonergodic systems, to which physical concepts are not well suited. As an alternative proposition, we have developed rigorous possibilistic, process-based models inspired by the discrete-event systems found in computer science and produced a panel of outputs and tools to analyze the system dynamics under examination. The state space computed by these kinds of discrete ecosystem models provides a relevant concept for a holistic understanding of the dynamics of an ecosystem and its abovementioned properties. Taking as a specific example an ecosystem simplified to its process interaction network, we show here how to proceed and why a state space is more appropriate than a corresponding potential surface.

Loss of heterozygosity in tumor-related genes in patients with squamous cell carcinoma of the larynx

I n t r o d u c t i o n. Allelic deletion in cancer can be detected by analyzing the loss of heterozygosity (LOH). The aim of our study was to search for LOH in specimens of squamous cell carcinoma of the larynx (SCCL), using markers linked to chosen genes involved in carcinogenesis, such as: MLH1, HPC1, MSH2, TP53, the unknown tumor suppressor gene at 8p22, NM23 (NM23-H1, H2, H3), MET, APC. M a t e r i a l. 62 patients with primary SCCL – analyses were performed on DNA isolated from larynx tumor tissues and corresponding peripheral blood lymphocytes. M e t h o d s. PCR reactions and analyses of amplified fragments in ABI -377 were carried out following standard procedures. Genescan and Gentyper software (Applied Biosystems) were used to measure, quantify and compare normal and tumor DNA patterns for each fluorescent marker. An allele ratio of less than or equal to 0.7 was taken to be indicative of LOH. Re s u l t s. Specific LOH was observed for markers linked to the following genes: MLH1 – 3p22 (47.9%), the unknown tumor suppressor gene at 8p22 (37.3%) and NM23-H1 – 17q21 (21.8%). We observed a positive correlation between lymph node metastases and LOH frequency for NM23-H1 (p<0.05). An association was also found between the frequency of LOH in NM23-H2 and both lymph node metastasis N1 (p<0.05), and advanced stage of the disease (p<0.05). C o n c l u s i o n. Our results confirm the observations of other authors, that allelic loss in the following genes: MLH1, the unknown tumor suppressor gene at 8p22 and NM23, plays an important role in SCCL carcinogenesis.
QTAIM Perspective

The metal pnictides which composed of transition metals and group 15 elements, have been the object of scientific research, mainly due to the variety of physical and chemical properties observed among the high number of possible phases [1]. Additionally, some metal pnictide phases show good magnetic properties like magnetostrictive and magnetocaloric effects, while others are important catalysts in reactions of significant industries [2], the iron or iron/manganese clusters containing arsenic act as important single-source precursors for phases of metal pnictide [3, 4]. The Quantum Theory of Atoms in Molecules [5-7] is a widely insightful tool using the charge density analysis for different molecules. During the last years, under the perspective of the quantum theory AIM [7-10], the topological calculations of the electron density become widely used for studying the chemical bonding. More recently; there are significant number of researches about light atoms systems (periods 1-3) which give useful relations between Theoretical study of Fe–Fe bonding in a Series of Iron Carbonyl clusters [(μ-H)2Fe3(CO)9(μ -As)Mn(CO)5], [Et4N] [(μ-H)2Fe3(CO)9(μ -As)Fe(CO)4] and [Et4N][HAs{Fe2(CO)6(μ-CO) (μ-H)}{Fe(CO)4}] by QTAIM Perspective Muhsen Abood Muhsen Al-Ibadi1 and Khulood Obaid Kzar1,2,* 1Department of Chemistry, College of Science, University of Kufa, Najaf, Iraq 2Department of Chemistry, College of Science, University of Kerbala, Kerbala, Iraq Egyptian Journal of Chemistry http://ejchem.journals. ekb.eg/ Egypt.J.Chem.

Interacting with the State as an Incentive for the Political Participa- tion of Long-Term Unemployed Youth

This paper examines the impact of interactions with welfare institutions on the political participation of long-term unemployed youth in two cities. We assess the role of resource redistribution and of political learning on engagement in protest activities. We use a unique dataset of long-term unemployed youth to predict the probability that long-term unemployed youth participate in protest activities and become politically alienated as a result of their interactions with the state. Our study suggests that the impact of staid aid on political participation comes from providing services through the unemployment office and the social aid office rather than from direct payments. However, we do not find strong evidence revealing a process of political learning, as political alienation does not seem to mediate the effect of interactions with  Results presented in this paper have been obtained within the project “Youth, Unemployment, and Exclusion in Europe: A Multidimensional Approach to Understanding the Conditions and Prospects for Social and Political Integration of Young Unemployed” (YOUNEX). This project was funded by the European Commission under the 7th Framework Programme (grant agreement no. 216122).

The most important finding of our study is that the connection between welfare institutions and political learning is context-dependent. We find a differential effect of interactions with the unemployment office and with the social aid office across cities.
3D-IMAGING AND ANALYSIS OF MULTI-COMPONENT POLYMER MORPHOLOGY STUDIED BY X-RAY TOMOGRAPHY

We have developed a high-contrast X-ray computerized tomography (CT), and applied it to the polymer blend systems, and composites. At first, the bicontinuous phase-separation structure in PS/PMMA system is clearly visualized by X-ray CT without any staining. The contrasts of the polymers under X-ray CT are comprehensively surveyed, and the capability of X-ray CT in polymer systems was critically examined. Then, the X-ray CT is applied to various polymer systems, such as, binary polymer blends, ternary polymer blends, and polymer composites.
A Wess-Zumino Scenario for Visible and Dark Matter with Matter-antimatter Asymmetry

We extend a previous Wess-Zumino Lagrangian inspired preon model of visible matter to include the dark sector with both bosonic and fermionic fields. The bosonic sector is assumed to be axion-like particles. They candidates for both dark matter and dark energy depending on the axion masses. A compatible supergravity model is cited for inflation. We propose a novel mechanism for the creation of the matter-antimatter asymmetric universe. Dark matter consists mainly (some 90\%) of bosonic particles and e.g. primordial black holes and the rest is fermionic particles or celestial bodies. Dark matter is more smoothly distributed in the universe than visible matter.
Reconstruction using Depth of Interaction Information of Curved and Flat Detector Designs for Quantitative Multi-Pinhole Brain SPECT

Objectives: Brain SPECT has many clinical applications, especially for cerebral blood flow and dopamine transporter imaging [1,2]. In this context, we are designing AdaptiSPECT-C, which is a dedicated brain imaging, multi-pinhole system. Recent studies in cardiac and small animal imaging have demonstrated that the use of curved detector could improve image quality, by reducing parallax errors due to depth of interaction (DOI) effect [3,4]. In this simulation study, we proposed to investigate the potential advantage in imaging performance of curved over flat detector for 123I (IMP) brain imaging using the AdaptiSPECT-C system.
Land cover change detection in northwestern Vietnam using Landsat images and Google Earth Engine

Recently, Google Earth Engine (GEE) provides a new way to effectively classify land cover utilizing available in-built classifiers. However, there have a few studies on the applications of the GEE so far. Therefore, the goal of this study is to explore the capacity of the GEE platform in terms of land cover classification in Dien Bien Province of Vietnam. Land cover classification in the year of 2003 and 2010 were performed using multiple-temporal Landsat images. Two algorithms – GMO Max Entropy and Classification and Regression Tree (CART) integrated into the Google Earth Engine (GEE) platform – were applied for this classification. The results indicated that the CART algorithm performed better in terms of mapping land use. The overall accuracy of this algorithm in the year of 2003 and 2010 were 80.0% and 81.6%, respectively. Significant changes between 2003 and 2010 were found as an increase in barren land and a reduction in forest land. This is likely due to the slash-and-burn agricultural practice of ethnic minorities in the province. Barren land seems to occur more at locations near water sources, reflecting the local people’s unsuitable farming practice. This study may provide useful information in land cover change in Dien Bien Province, as well as analysis mechanisms of this change, supporting environmental and natural resource management for the local authorities.

-Automatic assembly of two rigid objects with small clearance and position uncertainty has not been fully solved in robotics. Present solutions (increasing robot precision, improving object design, using passive compliance, using sensors with preprogrammed strategies . ) do not lead to completely automatic assembly systems. We propose a new methodology to automatically generate an assembly plan based on position and force information, considering several kinds of uncer tainty, friction forces and rotational degrees offreedom. Tasks states are defined according to the occurrence of different sets of basic contacts, and state transition operators are established to move through.them. Task execution consists in indentifying present state and applying a selected associated operator, until the goal state is reached.
Sol-gel Synthesis of Copper, Silver and Nickel Nanoparticles and Comparison of their Antibacterial activity

The present study involves a novel microwave assisted synthesis of metal nanoparticles which was carried out using Geraniol as a reducing agent. In this method water is used as the medium for reduction. Nanoparticles were studied with a wide variety of capping reagents such as starch, PEG and Gelatin. The medium was kept alkaline during the reaction using 5% NaOH solution. Formation of Copper nanoparticles (CuNPs) was indicated by absorption band at 540nm whereas Silver nanoparticle (AgNPs) gave a band at 420nm, with nickel nanoparticles (NiNPs) the band appeared a 390nm. The variation in λ max value is due to nature of metal and size of metal nanoparticles, as a small nanoparticle absorbs at higher wavelength. The characterization of metal nanoparticles was done by TEM (Tunneling electron microscopy) and XRD (X-ray diffraction) studies. Antimicrobial studies were carried out to check the zone of inhibition around these particles and it was found that silver nanoparticles were most effective followed by copper and nickel nanoparticles.
