Infrastructure in the form of bridges is very important for Buntok Regency in Central Kalimantan where the area is swampy or lowland area. Total wood bridge construction is 45% from total 163 bridge in this area that most of them are not proper condition considering some wood materials need to be replaced. The innovation has been created to find the effective way how to maintenance the wooden bridge that has been idle for long time due to broken material on superstructure of the bridge. The floor of bridge that constructed with previous materials of ulin wooden bridge replaced by composite materials with floordeck concrete combination. The implementation of Tampa Bridge maintenance innovation showed better performance in terms of safety, comfortable and smoothness of bridge users from community around. In terms of budget aspect, the maintenance is cumulatively more efficient than if carrying out floor changes every year considering no longer possible to find ulin wood anymore. On technical point of view, with reinforced concrete can be applied to wooden bridges selectively only on ulin wooden bridges whose substructure is still intact and only minor damage to the spoorband and floor occurs. Bridge maintenance procedures need to be create to keep better maintenance for longer life time of the existing bridge that can be applied for another wooden bridge for maintenance.

Liquid Flame Spray

Abstract Superhydrophobic nanoparticle coating was created on the surface of board using liquid flame spray (LFS). The LFS coating was carried out continuously in ambient conditions without any additional hydrophobization steps. The contact angle of water (CAW) of ZrO2, Al2O3 and TiO2 coating was adjusted reversibly from >150° down to ~10−20° using different stimulation methods. From industrial point of view, the controlled surface wetting has been in focus for a long time because it defines the liquid-solid contact area, and furthermore can enhance the mechanical and chemical bonding on the interface between the liquid and the solid. The used stimulation methods included batch-type methods: artificial daylight illumination and heat treatment and roll-to-roll methods: corona, argon plasma, IR (infra red)- and UV (ultra violet)-treatments. On the contrary to batch-type methods, the adjustment and switching of wetting was done only in seconds or fraction of seconds using roll-to-roll stimulation methods. This is significant in the converting processes of board since they are usually continuous, high volume operations. In addition, the creation of microfluidic patterns on the surface of TiO2 coated board using simple photomasking and surface stimulation was demonstrated. This provides new advantages and possibilities, especially in the field of intelligent printing. Limited durability and poor repellency against low surface tension liquids are presently the main limitations of LFS coatings.

Organic light-emitting diodes (OLEDs) have drawn much attention in areas of displays and varied illumination devices due to multiple advantages, such as high brightness, high efficiency, wide viewing angle, and simple structure. However, the long-time degradation of OLED emission is a serious drawback. This degradation was investigated by past works, which pointed out that the degradation was induced by high-density currents through OLED component under the long-time operation [1][2]. Proposed by a past work [3], different reverse biases was imposed on OLED components in display frames to alleviate the long-time degradation on OLEDs. Most recently, along with the reverse bias, new pixel circuits [4][5] for AMOLED displays are designed to alleviate OLED degradation, thus successfully extending OLED life time. However, since emission luminances in different frame times during AMOLED displaying differs significantly for displaying varied images, the OLED degradation evolves in a highly unpredictable fashion. In this study, based on valid theories, the voltage across the OLED is first used as indicator for OLED degradation. Then the relation between the level of OLED degradation, in terms of OLED’s cross voltage, and the history of imposing reverse biases are precisely modeled. With the model, the degradation of the OLED under reverse bias to extend lifetime can be successfully predicted. Based on this model, engineers can then optimize the applied reverse bias on OLEDs to maximize the OLED lifetime for varied display requirement.

This paper is a response to Dale Hutchison’s recent arguments about the role of fairness in contract law after the Constitution. From the point of view of transformative constitutionalism, the paper argues that the fairness ‘debate’ in the South African law of contract should be approached as what it so patently is, namely, as evidence of a deep ideological conflict that has existed in our law of contract for a very long time, and that this debate now exists within the context of a larger debate about the appropriate transformative reach of the Constitution. The argument takes the form of two ‘dangerous supplements’ to Hutchison’s discourse. The first of these supplements contends that indeterminacy is a symptom of the common law itself, rather than a result of contract law’s contact with the Constitution. The second dangerous supplement suggests a responsible judicial engagement with bona fides and ubuntu, one that can exploit the strengths of both the common law and the Constitution and that understands good faith and ubuntu to be ‘inter-linking’ constitutional values that should be enlisted in unison or at least in resonance when it comes to the question of fairness in our contemporary law of contract. In conclusion, I offer a reading of Hutchison’s own politics of contract law and contend that his is an altruistic politics committed to the standard form. I contend that this politics of contract law is consistent with a transformative understanding of the post-apartheid legal order. ‘Law, like every other cultural institution, is a place where we tell one another stories about our relationships with ourselves, one another, and authority. In this, law is no different from the Boston Globe, the CBS evening news, Mother Jones, or a law school faculty meeting. When we tell one another stories, we use languages and themes that different pieces of the culture make available to us, and that limit the stories we can tell. Since our stories influence how we imagine, as well as how we describe, our relationships, our stories also limit who we can be’.

Recently, anti-fouling paints which does not include the poison components such as tin (Sn) free, copper (Cu) free have been increasingly developed in order to decrease the contamination of marine environment. Moreover, the wear ratios of these anti-fouling paints are very important problem to prolong their life time in economical and environmental point of view. In this study, four types of anti-fouling paints as self-polishing type were investigated on the relationship between their polarization characteristics and wear ratios. Relationship between wear ratio and variation ratio of polarization resistance measured in corrosion potential was not well matched with each other. However, there was a good agreement between the wear ratio and variation ratio of diffusion limiting current density, for example, the higher or the lower variation ratio of diffusion limiting current density, wear ratio also increased or decreased respectively. Consequently, it is suggested that we can qualitatively expect the life time and wear degree of anti-fouling paint by only measuring the polarization characteristics before the wear test is practically performed in the field.Keywords: Anti-fouling paint, Self-polishing type, Polarization characteristics, Wear ratio, Diffusion limiting current density, Corrosion Potential

This Article may be situated within the rapport field between Philosophy and Social Sciences, at the search regarding to the concept concerning the Representation. Regarding to Philosophy, under a general view, the concept, concerning Representation, has been, since a long time, understood as a trail which one would get througl reaching to the real and true ones. Representation, as the thought contents expression form had not been known departing from Philosophy as a barrier against the objectivity concerning the knowledge. Representation, in its source, has been constituting itself a cognictive, inmanent reflection, related to the conscience inner subjectivity. But departing from the episthemological point of view, it has been not so easy for the campus concerning the Culture Sciences as a totality. In the theory regarding to knowledge, the Social Sciences campus and, more specifically, in the human life Symbolic dimension constitutive aspects, it has been, often, accepted negatively as an entry door for the histotical social reality. Nowadays, one may conclude that the contents concerning the Culture are deeply rooted within the histotical reality, which may present new dimension the reading regarding to the Symbolical side concerning the human life, under the view regarding to the unseen aspect, such as the intellectualistic Western dominant Culture allows understanding the way which could be in.

Abstract. The microwave humidity sounders Special Sensor Microwave Water Vapour Profiler (SSMT-2), Advanced Microwave Sounding Unit-B (AMSU-B) and Microwave Humidity Sounder (MHS) to date have been providing data records for 25 years. So far, the data records lack uncertainty information essential for constructing consistent long time data series. In this study, we assess the quality of the recorded data with respect to the uncertainty caused by noise. We calculate the noise on the raw calibration counts from the deep space view (DSV) of the instrument and the Noise Equivalent Differential Temperature (NEΔT) as a measure for the radiometer sensitivity. For this purpose, we use the Allan Deviation that is not biased from an underlying varying mean of the data and that has been suggested only recently for application in atmospheric remote sensing. Moreover, we use the bias function related to the Allan Deviation to infer the underlying spectrum of the noise. As examples, we investigate the noise spectrum in flight for some instruments. For the assessment of the noise evolution in time, we provide a descriptive and graphical overview of the calculated NEΔT over the life span of each instrument and channel. This overview can serve as an easily accessible information for users interested in the noise performance of a specific instrument, channel and time. Within the time evolution of the noise, we identify periods of instrumental degradation, which manifest themselves in an increasing NEΔT, and periods of erratic behaviour, which show sudden increases of NEΔT interrupting the overall smooth evolution of the noise. From this assessment and subsequent exclusion of the aforementioned periods, we present a chart showing available data records with NEΔT < K. Due to overlapping life spans of the instruments, these reduced data records still cover without gaps the time since 1994 and may therefore serve as first step for constructing long time series. Our method for count noise estimation, that has been used in this study, will be used in the data processing to provide input values for the uncertainty propagation in the generation of a new set of Fundamental Climate Data Records (FCDR) that are currently produced in the project Fidelity and Uncertainty in Climate data records from Earth Observation (FIDUCEO).

The problem of disintegration of the Islamic Ummah a long time ago became the one of the most important for the Islamic world and worldview. The wave of violence in the Near and Middle East sharpened some regional conflicts, which have already taken place before. The paper deals with the roots of this conflict atmosphere in the Early Islamic period. As the tradition affirms, the Prophet Muhammad predicted the Ummah to split in 73 sects. Today there exist in any case not less than 73 different Islamic schools, movements and organizations, which mutually and constantly contest their doctrinal authenticity. Moreover, the activity of quasi- Islamic extremist organisations like the ISIS, which is forbidden inside as well as outside the Russian Federation, is quite remarkable. All these factors demonstrate, that from the academic point of view it is actual to critically research the nature of fragmentation and disintegration of Islamic communities through the prism of prophetic legends. This paper is to consider as an attempt to resolve this multidimensional problem.

Prescriptive Grammar

Dutch prescriptive grammar rules dictate that the complementizer dan ‘than’ should be used in comparative constructions of inequality. This has been an issue for grammarians from the sixteenth century onwards when als ‘as’ started to be used as an alternative form in this type of context. In order to find out why and when people choose one comparative marker over the other, we examined the use of these markers in the Spoken Dutch Corpus (CGN). We found that the use of dan is overall more common than als in comparative constructions of inequality, even though from a linguistic point of view als might be favoured. The choice between als and dan turns out to be strongly correlated with the level of education. Although this factor has been assumed to be of influence for a long time, as far as we know it has never been quantitatively tested before. We conclude that the effect of the level of education we found reflects the strong influence of the prescriptive rule taught in schools, repressing the use of als in comparatives of inequality.

Narrative Function

The narrative dates from a long time ago and the subject of its research was to study fundamental principles of narration.It is so old that the ideas of its structure have been developed in the ancient times. The etymology of the term "narrative", is derived from the Latin and its meaning is narration. This term was emerged in the literary studies as a result of novelist works by Roland Bart, Claude Bremann, Cvetan Todorov and others. In the twentieth century, many theories were created about the narrative, and in the same century, the main analytical components of narrative - story, sound, time, point of view, character, role were established.Narrative can be considered as a feature of postmodernism, because narrative sources take special significance in postmodernism.While researching modern literature a significant function is given to the variety of narrative usages. The aim of the theme is to research the narrative function on the basis of comparative analysis of Aka Morchiladze's creative works.Aka Morchiladze's novels are filled with familiar literary or historical motives, acting people, stories, but itcreates a different reality through narrative or literary plays.The author creates a narrative text based on literary texts and "historical information". Historical information that is used in the text does not correspond to reality, and we, the readers, think that we are about to learn “historical novel” and the narrator is a historian,-not a novelist. Finally, we realize that we deal with the "fake history", allusion of writer's fantasy and literary and historical facts. Therefore, with regards of the presented issues, it is necessary to take into consideration the specificity of postmodern literature and peculiarities of realization of this specificity in Georgian reality. Narrative sources are of particular importance in postmodernism, which is one of the most important elements of the study of the text to be analyzed.

Cardiac tumors are a rare pathology, especially among infants. For a long time, they were identified only on the autopsy or as an incidental finding during cardiovascular interventions. However, with additional experience, improved methods of the echocardiography and wide-scale introduction of additional diagnostic methods, such as computed tomography (CT) and magnetic resonance imaging (MRI) into practice, it has become possible to establish a life-time and, recently, even a prenatal diagnosis of this pathology. The presented clinical case demonstrates the need to apply an integrated approach and potential of applying such diagnostic methods as echocardiography, MRI, multi-spiral CT and positron emission tomography/CT in children with cardiac tumors for the diagnostics of the severity of the cardio-vascular defects, determination of treatment tactics and prognosis of a therapy.
