The Effectiveness of Active Screen Method in Ion Nitriding Grade 5 Titanium Alloy

The study assessed the effect of ion nitriding on the properties of the surface layer of Grade 5 titanium alloy used, among others, in medicine. Titanium and its alloys have low hardness and insufficient wear resistance in conditions of friction which limits the use of these materials. The improvement of these properties is only possible by the appropriate modification of the surface layer of these alloys. The ion nitriding process was carried out in a wide temperature range, i.e., 530–590 °C, and in the time range 5–17 h. Two variants of nitriding were applied: cathodic (conventional) nitriding and nitriding using the active screen method. The research results presented in this article allow for stating that each of the applied nitriding variants improves the analysed properties (nitrogen diffusion depth, hardness, wear resistance, microstructure analysis and surface topography) of the surface layers in relation to the material before nitriding. The hardness increased in every nitriding variant (the use of the additional active screen increased the hardness to 1021 HK0.025). The greatest increase in titanium abrasion resistance was found for surfaces after cathodic nitriding with an active screen. Each of the applied nitriding variants resulted in surface development.
Decision-Making Experiences: Perspectives on M-Commerce and Decision-Making Experiences: Perspectives on M-Commerce and E-Commerce E-Commerce

We explore multi-channel decision-making experiences, especially in m-commerce and e-commerce. 232 e-mail messages sent by participants in two experiments are analyzed using Critical Incident Technique (CIT). Our findings suggest that decision-making in m-commerce is perceived as stressful and not necessarily a positive experience. We also find that participants in m-commerce hold their prior experiences in e-commerce as points of reference to which they compare their current or subsequent decision-making experiences. Cost Theory and Expectation-Confirmation Theory provide possible explanations for the findings. We identify and categorize factors that influence decision-making (shaping positive and/or negative decision-making experiences) and identify unique and channel-specific factors.
Optimization of a Dual-Band, Printed Octafilar Antenna

─ This paper presents several innovative techniques for the design and optimization of a dual band, octafilar helix antenna. The technical challenge of this design is how close the two bands of operation are, as well as the requirement to fit inside a radome with . 07λ diameter and . 33λ length. This was achieved through a novel technique of applying differing pitches and terminations to the upper and lower frequency antenna filars and then feeding them from a similar location at the base. This allowed for optimal current distribution on each of the two antenna filars. The final design produced gain greater than 0dBic at zenith across both bands of operation. The techniques discussed in this paper were seen to grow low frequency performance by as much as 2.5dBic over a typical octafilar design of the same size. Index Terms ─ Dualband, octafilar, QHA.
Application of Flood Hazard Potential Zoning by using AHP Algorithm

Flood in simply is the water flow which is higher than the average volume of a river [1]. Flood was the most common, deadliest and most costly natural disasters during decades. Flood risk has increased over time, especially since many of the construction license issued in floodplains and even commercial and residential growth [2]. In Iran, along with other parts of the world, the occurrence of floods has been increased significantly in recent decades. Therefore, the upward trend of flood in five recent decades show that the number of flood occurrences in the 2000s are ten times more than 1960s and in other words the amount has been increased by 900%. Drainage basin physical characteristics such as shape, drainage slope and topography of the land, together with hydrological characteristics such as precipitation, storage and losses and surface retention, evapotranspiration and infiltration and phenomena resulting from human activities, are involved in the intensity and duration of floods [3]. The understanding these factors and classifying in different zones are the basics of flood management and risks reduction [4]. Therefore, identifying these factors is very important. In other words, before any planning for flood control, we should understand the behavior of their processes [5]. Flood hazard zone maps are a valuable tool to identify the nature of floods and their effects on human life. Flood hazard zoning map can be effective tool in the planning the future development of the city, as well as identify areas that needed development of infrastructure, drainage and flood drainage [6]. Multi-criteria decision analysis (MCDA) methods are required to analyze complex decision problems, which often includes data and incomparable criteria. The success of Geographic Information System (GIS) and MCDA in the analysis of natural risks [7,8] and other environmental studies have already been proven [9,10]. Each of the factors affecting the occurrence of floods has a different role in the risk of its occurrence in the basin, as it can be prioritized due to the impact of each of these factors.
Actions Speak Louder than Words: Entity-Sensitive Privacy Policy and Data Flow Analysis with PoliCheck

Identifying privacy-sensitive data leaks by mobile applications has been a topic of great research interest for the past decade. Technically, such data ﬂows are not “leaks” if they are disclosed in a privacy policy. To address this limitation in automated analysis, recent work has combined program analysis of applications with analysis of privacy policies to determine the ﬂow-to-policy consistency, and hence violations thereof. However, this prior work has a fundamental weakness: it does not differentiate the entity (e.g., ﬁrst-party vs. third-party) receiving the privacy-sensitive data. In this paper, we propose P OLI C HECK , which formalizes and implements an entity-sensitive ﬂow-to-policy consistency model. We use P OLI C HECK to study 13,796 applications and their privacy policies and ﬁnd that up to 42.4% of applications either incorrectly disclose or omit disclosing their privacy-sensitive data ﬂows. Our results also demonstrate the signiﬁcance of considering entities: without considering entity, prior approaches would falsely classify up to 38.4% of applications as having privacy-sensitive data ﬂows consistent with their privacy policies. These false classiﬁcations include data ﬂows to third-parties that are omitted (e.g., the policy states only the ﬁrst-party collects the data type), incorrect (e.g., the policy states the third-party does not collect the data type), and ambiguous (e.g., the policy has conﬂicting statements about the data type collection). By deﬁning a novel automated, entity-sensitive ﬂow-to-policy consistency analysis, P OLI C HECK provides the highest-precision method to
Diagnostic Test of Urine Proteome during Atherosclerotic Process Among White Rat (Rattus Novergicus Strain Wistar) Induced by Atherogenic Diet

Introduction: Around twenty five million people in United State have at least one complications of atherosclerosis such as cardiovascular disease. Therefore screening in atherosclerotic process is important. Atherosclerosis is a multistage process that begins with damage to the endothelium due to LDL exposure. Angiography Coronary is the primary diagnostic tool for atherosclerosis. Imaging, as one way of non-invasive diagnosis, have limitation in sensitivity, specificity, and cost. Proteome urine analysis is alternative for atherosclerosis diagnostic. Objective: The aim of this study was analyse diagnostic performance of urine proteome among white rat (Rattus Novergicus strain wistar) induced by atherogenic diet. Material and methods: This study was quasi experimental in laboratory with randomized posttest only for control group design. The rat samples were divided to two groups i.e. group with atherogenic diet and non-atherogenic diet. Each group consisted of 10 rats. The treatment was done for 15 weeks. Urine sample collection was performed in week 16 of treatment. Urine proteome, collagen type I, was analyzed by ELISA to obtain biomarkers of atherosclerosis. Then determined sensitivity and specificity of the proteome urine analysis was compared with histopathology findings of the aortic arch and its branches. Result: In week 16, the researchers collected sample from 16 rats i.e. 11 rats with atherogenic diet and 5 ratswith non-atherogenic diet. Urine proteome, collagen type I, had area under the receiver operator with the characteristic curve of 98.2% (95% IK 92.6%-100%), p 0,003. The bestcut offis 0.9025 ng/ml with sensitivity of 100% and specificity of 90.9%. Conclusion: Urine proteome analyse, collagen type I, had high accuracy for atherosclerosis diagnostic.

On the Size of δ−SEPARATED δ−TUBES

In this preprint we will prove the surprising result that lim sup of the size of the Kakeya tube-sets are bounded below by a constant depending on the dimension. This implies that the δ−tubes are not an effective cover of a Kakeya set, because there exists Kakeya sets of zero measure. Our result is enough to prove the Kakeya conjecture. Our proof is an euclidean version of Dvir‘s proof of the finite field Kakeya conjecture.
The Value Proposition and Service Orientation Principle View of Service Oriented Architecture (SOA)

Businesses have become increasingly complex over the past few decades. Every aspect of business operation and service requires the use of information technology (IT), and many enterprises are showing a growing interest in service oriented architecture (SOA). Because they recognize the competitive advantage that can be achieved by linking all phases of the business operations and deliver business services to customers. However, the adoption of SOA in organizations and the configuration of IT in direct support of their business are a very complex process. This paper provides a broad discussion on the building of service oriented architecture from value proposition and service orientation principle point of view. A SOA model will provide the technology underpinnings for working with services that are value business activities. This will transform IT into building blocks and services that are easy to assemble and configure or reconfigure. In today’s changing business environment, the SOA provide a viable solution for enterprises to keep moving forward to the next level of business operations.
Vascular Reactivit After Balloon Angioplasty

Alterations in vessel wall reactivity (VR) at or adjacent to the dilation site after balloon angioplasty (BA) may vary according to the inflation protocol and the time after angioplasty and may influence outcome. In 64 atherosclerotic rabbit femoral arteries, we evaluated VR after BA with intravenous ergonovine (ERGO) (40 ,ug/min for 5 minutes) and intra-arterial nitroglycerin (NTG) (2,500 ,ug single bolus) 24-72 hours and 28 days after BA. Comparisons were made with atherosclerotic, nonangioplastied, age-matched controls. BA was standardized to three 1-minute inflations, each 1 minute apart. For each balloon size, 2.5(appropriate size) or 3.0-mm (oversized) vessels were allocated to either 5 or 10 atm inflation pressure. For the analysis, four groups were compared: Group 1, 3.0/5; group 2, 3.0/10; group 3, 2.5/5, and group 4, 2.5 mm/10 atm. Angiographic diameters were measured at, proximal, and distal to the lesion at baseline, 10 minutes after ERGO, and 5 minutes after NTG. Angiograms were measured with electronic calipers by two blinded observers. All segments of control vessels vasoconstricted to ERGO and vasodilated to NTG (p<0.05 versus baseline), indicating a normal response. At 24-72 hours after dilatation, the angioplasty sites for all inflation pressure/balloon size combinations were not responsive to either ERGO or NTG. All segments distal to the dilatation sites vasoconstricted to ERGO and dilated to NTG (p<0.05 versus baseline), indicating a normal response. Proximal segments of vessels dilated with a 2.5-mm balloon (appropriate size) responded positively to both stimuli (p<0.05). Those vessels dilated with a large balloon (3.0 mm) were nonreactive in the segment proximal to the angioplasty site. Twenty-eight days later angioplasty sites dilated with a 2.5-mm balloon (appropriately sized) regained reactivity; however, segments dilated with a large balloon (3.0 mm) remained unresponsive. All proximal segments, including those from vessels dilated with a large balloon, reacted positively. All distal segments reacted appropriately. Restenosis rates were not different between the overand appropriately sized balloon groups. These data demonstrate that immediately after angioplasty, vessels lose reactivity at the dilatation site. Those vessels dilated with the smaller-size balloon (2.5 mm) regained reactivity. For large balloons, reactivity is not regained at 28 days. For segments proximal to the site of dilatation, transient loss of reactivity is seen only when a large balloon is used. Thus, acute closure originating at the site of dilatation is not a result of spasm. In addition, no connection was found between restenosis rates and the ability of the dilatation site to react to ERGO and NTG. Finally, the vessel proximal, and especially distal, to the site of angioplasty remains highly reactive, and spasm originating at those sites may contribute to acute closure.

Computer Science Technical Report CORBA Based HLA/RTI Design Approach (cid:3)

DMSO’s effortto providea CORBA based, standard, common real time simulation architecture (High Level Architecture/Run Time Infrastructure, HLA/RTI) [1] for use in military, Civil Air Trafﬁc Control (CATC - USA, Europe, Canada), the entertainment industry and NASA has not produced a CORBA based implementation with adequate real time performance. The features that are desirable in an RTI implementation are described. A common HLA/RTI implementation that is suitable for the above applications is one that: 1) meets real-time performance requirements, 2) is the same implementation for all federations or simulations, 3) is implemented using commercial-off-the-shelf (COTS) software and hardware, 4) does not alter or compromise the modularity or present design of the RTI, and 5) allows users and owners of simulation applications and systems to retain control of their systems by not placing RTI functionality in line with their application code.

In-Vitro Nitric Oxide Scavenging and Anti-Tyrosinase Activity of Two Convolvulus L. Species

Convolvulus L. is a member of Convolvulaceae family which have been utilized for their biological activities in folk medicine. The aim of this study is to investigate the inhibitory effect on tyrosinase activity of two Convolvulus species as well as their nitric oxide (NO) scavenging activity potentials. Up to now, no reports have been found on their antityrosinase and NO scavenging activity properties in the literature. C. galaticus and C. phrygius aerial parts were extracted with methanol and then NO scavenging activity assay was utilized for the assurance of radical scavenging activity of the extracts. Anti-tyrosinase activity of the extracts was determined using the modified 96-well microplate method. The highest NO scavenging and anti-tyrosinase activity were found in C. galaticus as 55.20% and 53.16%, respectively.

Therefore, the CT scan is recommended to predict the likely outcome of treatment.
CRACKED SOILS BEHAVIOR DUE TO DRYING CONDITIONS USING A FUZZY C-MEANS METHOD

The drying cycle can affect embankments based ontheir physical properties and induce soil cracks. This paper investigates the unsaturated physical behavior of material from flood embankments located at the Bengawan Solo River, Pelangwot village, Bojonegoro, East Java, Indonesia. The volumetric shrinkage and degree of compactedness of the soil are important factors that control the soil behavior due to dry conditions. Some tests were conducted to study the desiccation process, in which soil samples were placed in a circular desiccation plate with soil thickness of 10 mm and a 100 mm plate diameter. A water retention curve was obtained to analyze the material properties during shrinkage. Next, the effect of the drying process on geometric characteristics of crack patterns was analyzed by image processing. Then, photo records of cracked soil from laboratory tests were assessed to determine the soil crack intensity via a Fuzzy C-Means (FCM) method using MATLAB software. The image analysis results show that the geometric characteristics of crack patterns were influenced by the drying process with a decrease in water content at 10% intervals until the air-dried condition was achieved. This is consistent with field observations; this indicates that image processing can be used quantitatively to analyze the drying process dependency of soil cracking behavior.

Factores sociales asociados con la utilización de los servicios de atención prenatal en Ecuador

RESUMEN Objetivos La atencion prenatal es uno de los pilares de la salud publica y permite el acceso a intervenciones tales como la prevencion de la transmision materno-infantil del VIH y de la sifilis congenita. Este articulo tiene como objetivo describir los factores sociales asociados con la utilizacion de los servicios de atencion prenatal en Ecuador. Metodos Entre 2011 y 2012, se realizo un analisis de la informacion procedente de las historias clinicas y de la entrevista a las participantes, que integraron una muestra probabilistica a nivel nacional de 5 998 mujeres atendidas por parto o aborto en 15 servicios sanitarios en Ecuador con el objetivo de estimar la prevalencia de VIH, sifilis, enfermedad de Chagas y la cobertura de atencion prenatal. Resultados El estudio mostro que 94,1% de las mujeres habia acudido a algun control prenatal, pero la asistencia al menos a cuatro controles fue 73,1%. Se encontro que el menor nivel educativo, el mayor numero de embarazos, la ocupacion en el sector agricola o ganadero y la pertenencia a los grupos etnicos indigena, afroecuatoriano u otros minoritarios fueron factores asociados con la falta de uso (ningun control prenatal) o al uso inadecuado de la atencion prenatal (menos de cuatro controles o primer control despues de las 20 semanas de gestacion) en Ecuador. Conclusiones Estos resultados apuntan a la persistencia de desigualdades marcadas en el acceso y en la utilizacion de servicios de atencion prenatal atribuibles a factores socioeconomicos y a la necesidad de fortalecer las estrategias para su abordaje para alcanzar la meta de la cobertura universal de atencion prenatal.
Does It Matter? A New Institutional Economics Prespective on B2B E-Commerce Adoption In Greater China and USA

Grounding on new institutional economic theory, this paper studies the impact and effect of institutional environment on Business-to-Business (B2B) e-commerce adoption in the Greater China region and USA. In a two-phase study, we find that 1) industrial pressure is always the most powerful external facilitator for B2B e-commerce adoption; 2) at the beginning stage of e-commerce, supportive government policy was a prime force to encourage private sector to adopt e-commerce; and 3) as e-commerce becomes more prevalent and routine in business, e-commerce adoption is more business-driven and governmental policy loses its influence. The study is one of the first cross-country studies on the institutional environment and fills the knowledge gap of understanding the external environment of e-commerce.
