    HydroQual Laboratories is a wholly-owned subsidiary of Golder Associates and uses biological testing for measuring the effect of toxins and their impact on various links in the food chain in order to evaluate and improve environmental health. It has expertise in various fields of the natural sciences and is ISO certified. This presentation discussed the use of DNA technologies in determining the biotreatability of chlorinated aliphatic hydrocarbons. The paper presented biotreatability studies run by the company which included bench scale testing on various types of contaminants. The testing involved multiple treatments, determination of dosage, and additional amendments. The strategy may vary based on bench test results and legislation. Trichloroethylene/perchloroethylene remediation strategies were also presented for chemical oxidation; aerobic bioremediation; abiotic remediation; and anaerobic biostimulation and augmentation. Biostimulation was defined as the addition of nutrients to influence the redox potential. The presentation also reviewed anaerobic dehalorespiration; detection methods; DNA isolation; polymerase chain reaction (PCR); and biotreatability case studies. The presentation concluded with some future directions and other uses of PCR. tabs., figs.

    Full Text Available The author brings forth a range of information on forced migration of the Serb population from the Croatian part of the Independent State of Croatia in 1941 (NDH. Almost one third of the population were Serbs in the NDH. One of the methods of solving “the Serbia issue” in the NDH was migrating the Serbs into Serbia. The other methods were forced conversions of the Serbian population, namely physical killings. The adopted legal provisions made the terror policy over Serbian population legitimate. A conference was held on June 4th in the German legation in Zagreb. At the meeting it was agreed that Slovenians from Styria were to be moved to NDH, and Serbs from the NDH to Serbia. Deportation was to be carried out in three waves. The first wave was to last from June 7th to July 5th and 5000 Slovenian intellectuals from Lower Styria were to be deported directly to Serbia, except for catholic priests who were to be deported to the NDH. Orthodox priests from the NDH were to be deported to Serbia together with their families. In the second wave, lasting from June 10th to August 30th, 25,000 Slovenians from Slovenia were to be deported to the NDH and NDH was to deport just as many Serbs. In the last wave (from September 15th to October 31st, 65,000 Slovenian peasants from the Gorenjska region (Upper Carniola region were to be deported to the NDH, and NDH was to migrate just as many Serbs to Serbia, as well as 30,000 Serbs whose citizenship was not acknowledged by the NDH. The government of the NDH founded an office for this purpose under the name State Directorate for Renewal. The migration of the Serbs from NDH began in June of 1941. Volunteers from the Salonika Front were then moved from their properties in Slavonia and Srem. Their total number was about 28,000. Then the Orthodox priests were migrated. According to the lists made by the NDH authorities, 327 of them were migrated from the NDH. 104 priests from the Croatian part of NDH were moved away

    Full Text Available The weakening of the SFRY (Socialist Federative Republic of Yugoslavia which was followed by its dissolution, had an impact on a wide range of issues, one of them being the degradation of the so called Serbo-Croatian language. Not only did the external political influences contribute to the dissolution of the SFRY, but they also play a part in the linguistic profiling of new standard varieties today. However, as the dissolution of Yugoslavia couldn't have been imagined without consequences for Serbs primarily, the transformation of the 'Serbo-Croatian' language into a series of new language norms-successors of the old ones, cannot take place without challenging the rights of the great number of Serbs who live outside of Serbia. These are the rights that primarily refer to the linguistic and social identity - therefore the national identity. The best illustration of this are the external influences in the domain of linguistic engineering today, and these influences can basically be divided into extensive (e. g. commercials, radio and TV programmes and intensive (textbooks, handbooks etc. The aim of this study is the analysis of those different kinds of pressures put on the standard variety of the language of Serbs. From the domain of the extensive influences (commercials there is an example of the instruction given on a tube of toothpaste (Vademecum laboratories, Perfection 5 - Schwarzkopf & Henkel, Dusseldorf - Germany, and as an example of the intensive influences of this type, there is an American textbook (R. Alexander, E. Elias-Bursa} Bosnian, Croatian, Serbian, a Textbook, With Exercises and Basic Grammar, The University of Wisconsin Press, 2006. Both of these language materials proved to be highly compatible when it comes to the characteristics that should become an integral part of the standard language variety of Serbs, and apparently only the Serbs who live in Serbia. Among the language characteristics which are 'typically Serbian' the

  6. Serbs as threat the extreme negative portrayal of the Serb “minority” in Albanian-language newspapers in Kosovo

    2011-01-01

    Full Text Available Through perpetuating negative stereotypes and rigid dichotomous identities, the media play a significant part in sustaining conflict dynamics in Kosovo. Examining their discourse in terms of ideological production and representations is crucial in order to understand the power relations between the majority and the minority, the identity politics involved in sustaining them, and the intractability of the conflict. In an effort to provide a deeper understanding of the intractable conflict in Kosovo, and the role of the media in protracting it, this study uses critical discourse analysis to examine articles related to issues affecting the Serb community, published in Albanian language print media. The master narrative that comes out of the analysis is that of “threat” - the threat that Kosovo Albanians continue to face from Serbs and Serbia; a threat that is portrayed as historical and constant. The discourse further strengthens the conflict dynamics of opposition, polarization and even hatred. This master narrative implies that Serbs are enemies, to be feared, contested, fought against; conflict is thus the normal state of affairs. The study also looks at the implications of media discourse for reconciliation efforts and the prospects of the Serb minority in Kosovo society, arguing that when the Other is presented as dangerous and threatening, fear of the Other and a desire to eliminate the threat, physically and symbolically, become perceived as a “natural” response, and thus constitute a significant conflict-sustaining dynamic.

  7. Nation-building under the Austro-Hungarian sceptre Croat-Serb antagonism and cooperation

    Full Text Available In the nineteenth century many European nations, including Serbs and Croats became politically conscious of their "nationhood", which became a contributory factor in the crumbling of the two great empires in Central-East Europe - the Habsburg and the Ottoman - at the beginning of the following century. The Serbs had, since medieval times, an awareness of their long history and tradition, great medieval civilization and cultural unity regardless of the fact that they lived under several different adminis­trations. As in the case of Habsburg Serbs, language and literature became building blocks of Croat national consciousness in the nineteenth century. Unlike Serb nationalism centred on people, Croat nationalism was mainly territory-related. Since both Serbs and Croats inhabited the Austro-Hungarian provinces claimed by the Croats as their "historical Right" (absorption in 1097 of the small medieval Croat state by the Hungarians is interpreted, by many Croat historians, as a voluntary act of union, the different conceptions of nationalism resulted in competing claims. Croatian politics became one of opposing any recognition of Serbian institutions and cultural characteristics without Serbs previously accepting the concept that the only "political nation" in the Austro-Hungarian Province of Croatia was Croatian. Nonetheless, Croats compromised when in need of Serb assistance in opposing Hungarian domination. In turn, Serb politics was divided between those supporting cooperation with the Croats in order to achieve greater autonomy from the Hungarians in the Dual Monarchy, and those who supported some cooperation but insisted on forming an entity separate from the Croats in the future and joining with the Kingdom of Serbia, which regained its independence in 1878. The ensuing world and civil wars brought the Croato-Serb conflict to the fore, with the first and the second Yugoslavia failing to accommodate the two nations' opposing aspirations.

    1996-01-01

    Biotreatment of oil wastes in aqueous slurries prepared with sandy loam soil and inoculated with selected soil cultures was evaluated. After 90 days, oil removal was 47%. Removal of each hydrocarbon class was 84% for saturates, 20% for aromatics, and 44% for asphaltenes. Resins increased by 68%. The use of a soil with a lower level of fine particles or minor organic matter content, or reinoculation with fresh culture did not improve oil elimination. Residual oil recovered from slurries was biotreated. Oil removal was 22%. Slurry-phase biotreatment showed less variability and faster oil removal than solid-phase biotreatment. (author)

    2006-07-01

    This presentation discussed improvements in the biotreatment of soil contaminated by heavy hydrocarbons. The presentation provided information on the background for the investigation such as: difficulty for biotreatment in soil to deal with heavy weathered hydrocarbons and fine grained soils; the involvement of the Montreal Centre of Excellence for Brownfield Remediation (MCEBR) to develop state of the art environmental solutions; and, the selection of Sanexen as the organization with the best price and best performance warranty to perform the required decontamination. The objectives of the study were to improve the performance of biotreatment of soil contaminated with heavy petroleum hydrocarbons; reduce soil biotreatment costs by 30 per cent; improve knowledge and understanding for this type of treatment; and, better identify constraints and optimal strategies in view of these constraints. Specific objectives that were discussed included: improving the microbial flora, attaining a favorable soil temperature at a low cost, identifying the best amendments for bulking of soil, increasing bio-availability of the contaminants, and identifying optimal mechanical handling of the soil. The presentation discussed soils treated; research and development carried out; standard method of biotreatment; alternative methods tested; initial investigation by the MCEBR; pilot test carried out by Sanexen; and, results of the pilot test. As part of the research program with MCEBR, soils that received different amendments were tested at the Biotechnology Research Institute (BRI) of the National Research Council for their ability to degrade added hexadecane and naphthalene. Soil at various stages of the treatment was also sampled and tested by the (BRI). It was concluded that the biotreatment of heavy hydrocarbons in fine grained soils is feasible and that the techniques used reduced biotreatment costs by approximately 25 per cent.

  10. Native language as an ethnic symbol Serbs in Timisoara

    2004-01-01

    Full Text Available Based on the data gathered during original research in the Serbian community of Timisoara, in 2002. and 2003, this paper discusses one of the symbols of ethnic identity, namely, the native language. The methods used in the research include questionnaires, interviews, everyday conversation and the participant-observation technique. The analysis covers various aspects and levels of knowledge, as well as the usage of Serbian language; in addition it also includes the most important features that influence the language's persistence during many centuries, as well as noted changes in a multinational environment. Namely, the Serbs in Timisoara have preserved their native, Serbian language as a second language; then-native Serbian language is constantly under the heavy influence of the Romanian language which is the dominant and official language in the area. The analysis shows that the knowledge of Serbian is much higher among the Serbs who received education in their native language, as well as among the older generation while mixed marriages with Romanians contribute to its loss. Romanian language, on the other hand, gradually becomes more and more dominant even in the traditional spheres of life where native language was once in use among family members, minority organizations and in interactions among Mends of Serbian origin. Moreover, mixed marriages and education in the native language influence the persistence of the native language. In spite of many changes in all aspects and usages, Serbian language still remains the symbol of ethnic identity among the Serbs in Timisoara: the language marks the special unity among the Serbs in relation to the surrounding majority and other ethnic groups in the city of Timisoara, and functions as a connection with the tradition and culture of the homeland.

    Full Text Available In this article the author analyses the institutional attempts to change national identity of the Serb people in Bosnia & Herzegovina in XIX and XX century. It is emphasized that every great war, conquest and occupation in the contemporary Bosnian-Herzegovina history were followed by imposing some sort of common identity to the national communities in B&H, including Serb people, and that it could be said that the attempts to suffocate and, more-less, violently change the identity of the Serbs, are as old as the modern national identity of this part of Serb nation - invading rulers of Bosnia & Herzegovina had invested great efforts to suppress national consciousness of the Serbs while it was still in the early stages of its development, and national awakening of the Serbs was, at the same time, followed by rough imposing of the alternative Bosnian identity. However, all these attempts to create common identities as ways to achieve stability and secure coexistence have had, for the most part, adverse effects and have led to the creation of even greater gap between peoples in B&H and further deepening of interethnic differences and animosities.

    Full Text Available This paper provides an overview of the basic characteristics regarding number, as well as normative and functional status, i.e. legal and institutional status of Serbs in Zagreb. Furthermore, the paper describes some distinctions among organizational levels of Serbian minority in Zagreb, concerning the most important aspects of socio-cultural, educational and religious integration. Serbian minority members’ number in Croatia and Zagreb is analyzed using an official demographic statistics, focusing primarily on major socio-demographic indicators, on population density and ethnic composition data for the population of Zagreb municipality for the period of 1981-2011. Legal position of the Serbian minority in Zagreb is described using analysis of official documents, including legislative framework provisions, which are related to issues of national minorities’ status and rights. Institutional and organizational status is elucidated by using descriptive analysis of cultural, educational, media and religious aspects of minority’s life. The number of Serbs in Croatia decreased drastically in last twenty years, affecting their number being reduced to approximately one-third of the prewar number. In the period 1981 to 2011 there was a continuous increase of number and proportion of Croatian majority population, and continuous reduction of national minorities in Zagreb. The biggest percentile decreasing in the municipality of Zagreb (during period 1991-2001 have undergone members of the Serbian (57.7%, Slovenian (48.9%, and Montenegrin (43.7% minority. In the case of Serbs, this is primarily and predominantly a consequence of forced emigration (displacement induced by the war in the 1990s. Moreover, negative demographic trends together with a possibility of “false” national declaration in census, as well as the relentless process of assimilation are counted as specific factors in reducing the number of national minorities’ members.

    2013-02-01

    The stringent regulations for discharging acid mine drainage (AMD) has led to increased attention on traditional or emerging treatment technologies to establish efficient and sustainable management for mine effluents. To assess new technologies, laboratory investigations on AMD treatment are necessary requiring a consistent supply of AMD with a stable composition, thus limiting environmental variability and uncertainty during controlled experiments. Additionally, biotreatment systems using live cells, particularly micro-algae, require appropriate nutrient availability. Synthetic AMD (Syn-AMD) meets these requirements. However, to date, most of the reported Syn-AMDs are composed of only a few selected heavy metals without considering the complexity of actual AMD. In this study, AMD was synthesised based on the typical AMD characteristics from a copper mine where biotreatment is being considered using indigenous AMD algal-microbes. Major cations (Ca, Na, Cu, Zn, Mg, Mn and Ni), trace metals (Al, Fe, Ag, Na, Co, Mo, Pb and Cr), essential nutrients (N, P and C) and high SO(4) were incorporated into the Syn-AMD. This paper presents the preparation of chemically complex Syn-AMD and the challenges associated with combining metal salts of varying solubility that is not restricted to one particular mine site. The general approach reported and the particular reagents used can produce alternative Syn-AMD with varying compositions. The successful growth of indigenous AMD algal-microbes in the Syn-AMD demonstrated its applicability as appropriate generic media for cultivation and maintenance of mining microorganisms for future biotreatment studies.

    2008-09-01

    Full Text Available In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB textile dye bath effluent using advanced oxidation processes (AOPs is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bath effluent was 58% in the case of ozonation. However it was 98% in the case of biotreated dye bath effluent when exposed to UV/H2O2. It is, therefore, suggested that a combination of biotreatment and AOPs be adopted to decolorize dye bath effluent in order to make the process more viable and effective. Biodegradability was also improved by applying AOPs after biotreatment of dye bath effluent.

    Živković Milorad

    2009-01-01

    Full Text Available This paper presents data which clearly reveal that the behavior model of young people in the Bosnian Serb Republic is characterized by an insufficient degree of information and poor knowledge on reproductive health, an increase in the number of alcohol consumers, drugs and cigarettes which leads to an increase in risky behavior, entering sexual relations and an earlier age, an increase in the number of sexually transmitted diseases and unwanted pregnancies which often result in abortions or premature birth. At the same time young people recognize the necessity for more information, mention competent authorities and expect help from them. At the same time, they show readiness to learn through peer education. On the other hand, the estimated results which we obtained by using available sources, because of the lack of a population census, give us information on the grave demographic situation in the Bosnian Serb Republic and negative tendencies in the future. When we speak of the total fertility rate and compare these data with countries of Europe and the surrounding areas, we can unfortunately only state that many factors - the most important being: war events, insecurity, unfavorable economic and social situation, significant migration of not only young people but of whole families - caused severely low total fertility rate in the Bosnian Serb Republic. Even worse, these tendencies are further decreasing and society is moving towards open depopulation with unforeseeable demographic, economic and national consequences. At the same time, it has been ascertained that young people are getting married at a later age, deciding on becoming parents at a later age and acting more riskily which decreases their fertility capacity and decreases their share in the total fertility capacity, making the already bad demographic picture of the Bosnian Serb Republic even worse.

  1. Serbs in political and military elites of the Ustaše's Independent State of Croatia

    2014-01-01

    Full Text Available The phenomenon of Serbian participation in the political and military elites and leadership of the Independent State of Croatia was not enough or rather not at all scientifically analysed and researched. The purpose of this paper is to inspire the historians of our recent past to research and critically evaluate the problems. In the beginning of the war during the establishment of the Independent State of Croatia, the Serbs were not involved in the Home Guard units as regular armed forces of Independent State of Croatia. Along with the development of the Independent Ustaš State of Croatia, the necessity for Serbian participation in Home Guard units arose. The Serbs were mainly educated in Austro-Hungarian schools for officers. They also participated in the armed forces of the Kingdom of Serbs, Croats and Slovenes i.e. the Kingdom of Yugoslavia. The most prominent among them were: Dr Savo Besarović, general Teodor Dragojlov, general Đuro Dragičević, general Đuro Grujić, a knight, general Milan Desović, general Mihailo Lukić, general Dušan Palčić, general Miroslav Opačić (Fridrich, a church official Zvonimir Stimaković, general Miloš Obrknežević, Minister without portfolio Ljubomir Antić, general Lalislav Milić, general Milan Uzelac and others. Apart from being the most prominent ones in the Home Guard units, there were Serbs in the political elites of the Independent State of Croatia, as well as in the Presidency of the Parliament and in the positions of the Ministers in the Independent State of Croatia. This phenomenon should be an example for future generations, in a case of war, not to happen that one part of the people takes the enemy side because the greatest sin ever is to betray its own people and country.

    Full Text Available One of the most important issues in the Kingdom of Serbs, Croats and Slovenes was the process of the agrarian reform. The agrarian reform was a complex state measure with an economic, social and political aspect. All political parties, due to political reasons, spoke in favor of the resolution of the agrarian issue through agrarian reform. Political parties kept in mind the large number of those individuals interested in the agrarian reform, as well as the fact that majority of the voters were farmers, when they formulated their position towards the reform. The Democratic Party was one of the most influential political party in the Kingdom of Serbs, Croats and Slovenes. The paper presents the basic concepts related to the agrarian reform and agricultural policy in the Kingdom of Serbs, Croats and Slovenes that represented the Democratic Party.

    Full Text Available The Slava has been a folk-religious holiday among the Serbs for centuries. As the cult of a specific Christian saint within the family (genus, tribe, a protector and giver, over time many common structural elements of the ritual emerged. However, the ways of celebrating, ritual meals and duration of the Slava have certain local variances which are caused by folkreligious traditions as well as the wider (state and socio-political context. From the 13th century onward the Slava has been under a strong influence from the Serbian Orthodox Church. The contemporary way of celebrating the Slava has been formed by the Church. Some authors have considered the Slava a marker of Serbian national identity. The Slava is a social and spiritual good passed down from father to son. In matrilocal marriage, the son in law accepts the Slava from his father in law, and keeps his own as secondary. Over the centuries there were many limitations and even bans on the practice of the Slava, most notably imposed on the Serbs by the Venetian republic and the Austro-Hungarian Empire - all with the aim of imposing a union of the faith with the Vatican and turning the Orthodox faithful over to Catholicism.

  4. Sources de Constantin VII Porphyrogénète concernant le passé le plus ancien des Serbes et des Croates

    2010-06-01

    Full Text Available THE SOURCES OF CONSTANTINE PORPHYROGENITUS CONCERNING THE EARLIEST HISTORY OF THE SERBS AND CROATSThere are eight chapters (29-36 in De Administrando Imperio by Emperor Constantine VII Porphyrogenitus that contain known historical information on the Slavs of the Balkan Peninsula. Commonly accepted knowledge in historiography tells us that Constantine Porphyrogenitus must have used references on the Serbs, the Croats, and other Slavs from the archives of the Imperial Palace and the verbal accounts of Byzantine administrative personnel who were stationed in Dalmatia. However, our analysis of the earliest historical text on the Serbs and the Croats described in chapters 30, 31 and 32 of the DAI has established that oral tradition could not have been the source of the information on the Serbs or the Croats but rather that Constantine utilized a written source with its approximately dated to around 878.The peculiar style of the source focuses on baptism (Conversio Croatorum et Serborum and the close ties of the Serbs and the Croats with Rome. This style or literary genre – De conversione – did not exist in Byzantium but was well known during early medieval times in the West. The analysis of the aforementioned chapters of the DAI established a high degree of correlation with parts of the text known in historiography under the title – De conversione Bagoariorum et Carantanorum. The connection between De conversione Bagoariorum et Carantanorum and chapters 30, 31, and 32 of the DAI is easily recognised in the conception of the work, and in the annexed parts by the author. It is our conclusion that we can now take a different path in analysing data on the earliest history of the Serbs and the Croats; it is evident that Constantine Porphyrogenitus used the information collected by an anonymous author who had been employed, very likely, as a high commissioner of the Roman Church.

    Dust is an environmental, geotechnical, health, and economical hazard. Fugitive dust emanating along transportation systems such as roads, railways, and airports especially can have significant impacts on health, safety, material loss, cost of maintenance, and interfere with the facilities. Quantitative studies on the effectiveness of the proper dust palliatives and their environmental impact have been studied with a number of biological and chemical methods. The objective of this study was to establish a method for using the microbial Induced calcium carbonate precipitation (MICP) approach to reduce the percent of mass loss against erosive force of wind regarding to the concentration and characteristics of aggregate used, climate, and traffic amounts. The results of this study showed that the required precipitation for dust control of sand by 70% is less than 15 g CaCO 3 /m 2 between sand grains in bio-treated sand. The wind tunnel test results of this study also indicate that the effectiveness of the bio-treatment method for dust control depends on many variables, such as the percent of precipitated calcium carbonate and tensile strength.

    Full Text Available The author analyses the effects of transition and war on the formation of some segments of national identity among Croats and Serbs. The basis for the analysis was an empirical survey conducted in Western and Eastern Slavonia. The analysis included three groups of war migrants and victims of war – indigenous Croats, indigenous Serbs and immigrants. The survey was conducted between September and December 2004, in villages and towns of Western and Eastern Slavonia. It used a survey questionnaire with 48 closed-type questions. The survey took account of the following variables among respondents: sociospatial status, age, gender and level of education. The analysed variable: respondents’ sociospatial status, proved to be in correlation with the perception of some segments of national identity among Croats and Serbs. The results of the survey showed differences in the opinions and evaluations of respondents from Western and Eastern Slavonia. Indigenous Croats, more than indigenous Serbs, stressed the meaning and importance of religion (Catholicism in national identity. Indigenous Croats were more exclusive than indigenous Serbs as to the possibilities of full participation of former Communists in the Croat and Serb national communities. The responses of immigrants were more radical and exclusive in comparison with indigenous persons, and in this regard responses of immigrants in Western Slavonia (mostly ethnic Croats were more radical than responses of immigrants in Eastern Slavonia (mostly ethnic Serbs. Although they were somewhat laced with exclusive opinions on the possibilities of including various subidentities in the national identities of Croats and Serbs, the respondents’ answers indicate that in the post-war period, in former war areas, tolerance is also quite present, more noticeably within one’s own group than towards the other nationality.

    The paper presents the advantage of the SERB-CITON innovative solution for increasing the seismic resistance of engineering structures as compared with other solutions for seismic protection of buildings. SERB devices (telescopic and isolation) used in an innovative solution to control, limit and damp the seismic building movement, have a capsulated structure and are capable to overtake large compression and tension loads with controlled deflection and large damping. The great difference in the building behavior during an earthquake results from the fact that a building (along with its foundation ground) make-up an oscillating system which represents a built-up of kinetic and potential energy of repeated seismic movement oscillations. The oscillating system may or not overtake and built-up the seismic energy from each soil oscillation, as a function of the location of the important Eigen vibration periods of the building within the spectral component of the seismic action. The main problem that needs to be solved by the seismic design of buildings consists in the transfer of a minimum amount of seismic energy from the ground to the building and in doing so for the transferred energy should not build-up in the building-ground oscillating system. The paper presents the classical, modern and innovative solution for mitigation of seismic actions. (authors)

  8. Serbs in the poetry of Theodore Prodromos and anonymous Manganeios

    2006-01-01

    Full Text Available Numerous rhetorical writings of the Comnenian period constitute a fruitful field of research, both with respect to historical data, i.e. hard historical facts hidden, though still recognizable, behind the peculiar and somewhat abstract mode of expression of the authors of the twelfth century, and with regard to the poetics of the literary works themselves, i.e. the internal elements characteristic not only for the genre chosen, but also for each particular author. A comparative, historical and literary approach to these works renders their sense clearer and their complex allusions more readily understood. This is a matter of some importance, since allusions constitute one of the basic elements of historical rhetoric, which reached its peak at the time of Emperor Manuel Komnenos (1143-1180, especially during the first half of his reign, i.e. till the end of the fifties of the twelfth century. The poetry of Theodore Prodromes and of the somewhat younger Anonymous ('Prodromos' Manganeios is an excellent example of this intertwining of historical and literary elements, i.e. of the presentation of historical data through rhetorical patterns. One has to concentrate on individual works attempting to determine, as far as possible, the date of composition, the circumstances of writing and the purpose of a particular poem, the occasion for which it was written and the character of the expected audience, in order to better understand both the poetry written by these two rhetoricians and the individual features of the authors, as well as their respective positions in the circle around Emperor Manuel Komnenos. The poems dealt with in the present paper stand out for calling the Serbs by their real name. This naming practice was invariably employed by both rhetoricians in cases when new achievements of the basileus were to be announced and proclaimed immediately after the event, on the occasions of first reports, first celebrations of the new victories and

    Full Text Available The breakdown of the former Yugoslavia has resulted in formation of new independent states while the former co-citizens and constitutive people have found themselves in new roles. Some have become a majority while some have become a minority, with an aspiration to affirm the status in the public sphere. As a country with a large numbers of immigrants from the former Yugoslavia, Slovenia is facing a challenge of the confirmation of ethnic pluralism within its borders, along with solutions and appropriate places for 'new' minorities (the usual appellation for ethnic groups formed by the members of the former Yugoslavia, where the Serbs are outnumbering the rest. At the same time, the new minorities face a challenge of constitution foundation of their own associations, that is, formation of their own identity and public affirmation in the new context. This paper discusses these ongoing processes with a special attention to the Serbian ethnic group.

    2015-04-01

    Full Text Available The article deals with how the 1990s civil war in Bosnia and Herzegovina was represented in the media that currently remain influential among Bosniaks and Bosnian Serbs. Critical discourse analysis is used both as a theoretical approach to discourse and as a methodological tool for its study. In the analysis, the civil war discourse in Bosniak and Bosnian Serb media is represented by two daily newspapers on each side. The analysis reveals mutually incompatible representations of the causes and nature of the war, the prevailing absence of dialogue, and the unwillingness of each side to consider the other side’s war victims. Looking at more specific topics, a number of discourses are identified on both sides, among which some present the potential for dialogue with alternative representations. The discourses are interpreted through Bosniak and Bosnian Serb nationalist ideologies. The findings might support further research on the relation between the media and nationalism and on the ongoing Bosnian political dispute concerning the desired nature of the state.

    Biotreated textile wastewater (CODo = 248 mg L(-1); TOCo = 58 mg L(-1); A620 = 0.007 cm(-1); A525 = 0.181 cm(-1); A436 = 0.198 cm(-1)) was subjected to advanced treatment with ozonation, granular activated carbon (GAC) adsorption in serial and simultaneous applications. Experiments were conducted to investigate the effects of applied ozone dose, ozone absorption rate, specific ozone absorption efficiency, GAC dose, and reaction pH on the treatment performance of the selected tertiary treatment scheme. In separate experiments, the impact of virgin GAC ozonation on its adsorptive capacity for biotreated and biotreated + ozonated textile effluent was also investigated. Ozonation appeared to be more effective for decolorization (kd = 0.15 min(-1) at pH = 3), whereas GAC adsorption yielded higher COD removal rates (54% at pH = 3). It was also found that GAC addition (4 g/L) at pH = 7 and 9 enhanced the COD abatement rate of the ozonation process significantly and that the sequential application of ozonation (at pH = 3-11, 675 mg L(-1) O3) followed by GAC adsorption (at pH = 3-7, 10 g L(-1) GAC) resulted in the highest treatment performances both in terms of color and COD reduction. Simultaneous application of GAC and ozone at acidic and alkaline pH seriously inhibited COD abatement rates as a consequence of competitive adsorption and partial oxidation of textile components and GAC. It could also be established that ozone absorption efficiency decreased after color removal was complete. Ozonation of biotreated textile wastewater with 113 mg L(-1) ozone resulted in an appreciable enhancement of GAC adsorptive capacity in terms of residual color removal. Ozonation of GAC at relatively low doses (= 10.8 mg/g GAC) did not improve its overall adsorption capacity.

    The major parcel of the degradation occurring along wastewater biotreatments is performed either by the native microbiota or by added microbial inocula. The main aim of this study was to apply two fingerprinting methods, temperature gradient gel electrophoresis (TGGE) and length heterogeneity-PCR (LH-PCR) analysis of 16S rRNA gene fragments, in order to assess the microbiota structure and dynamics during mixed olive oil and winery wastewaters aerobic biotreatment performed in a jet-loop reactor (JLR). Sequence homology analysis showed the presence of bacterial genera Gluconacetobacter, Klebsiella, Lactobacillus, Novosphingobium, Pseudomonas, Prevotella, Ralstonia, Sphingobium and Sphingomonas affiliated with five main phylogenetic groups: alpha-, beta- and gamma-Proteobacteria, Firmicutes and Bacteroidetes. LH-PCR analysis distinguished eight predominant DNA fragments correlated with the samples showing highest performance (COD removal rates of 67 up to 75%). Cluster analysis of both TGGE and LH-PCR fingerprinting profiles established five main clusters, with similarity coefficients higher than 79% (TGGE) and 62% (LH-PCR), and related with hydraulic retention time, indicating that this was the main factor responsible for the shifts in the microbiota structure. Canonical correspondence analysis revealed that changes observed on temperature and O(2) level were also responsible for shifts in microbiota composition. Community level metabolic profile analysis was used to test metabolic activities in samples. Integrated data revealed that the microbiota structure corresponds to bacterial groups with high degradative potential and good suitability for this type of effluents biotreatments.

    This paper is the result of original fieldwork performed in the village of Strelac, in southeast Serbia during August 2003. All Slavs believed in the existence of a vampire; still today, this belief is widespread among Serbs. According to the folk stories, a man can become a vampire during his life or after death. It is believed that certain persons have a predisposition to become vampires: informants argued that the condition could descend by inheritance, or if an animal steps over a decease...

    Full Text Available L’œuvre de Vuk Karadjitch et son évocation de l’image du Turc dans la poésie épique serbe. Persuadé que la poésie épique serbe porte une valeur exceptionnelle dans la formation de la langue elle-même ainsi que dans la constitution de l’identité nationale et de la mémoire collective, Vuk Karadjitch se hâte, durant toute sa vie, de rencontrer les chanteurs épiques-aèdes pour les écouter et noter les poèmes. C’est ainsi qu’il réussit à recueillir environ mille chants populaires.Les critères de systématisation de Vuk Karadjitch prennent en compte le contenu thématique des poèmes. Il divise les chants en deux familles : les poèmes féminins traitant des sujets appropriés, et les poèmes masculins qui évoquent les thèmes héroïques, les batailles, les guerres, les personnages et les événements importants de l’histoire. Les chants masculins sont au centre de nos recherches dans cette étude. Ces poèmes qui parlent des batailles sanglantes et de l’héroïsme national se situent historiquement à l’époque de l’envahissement turc des territoires serbes. Selon les différentes périodes de l’occupation ottomane, on peut voir l’évolution de l’image de l’occupant turc, construite dans l’imaginaire collectif. Dans la présence turque, les Serbes ne voyaient pas seulement l’envahisseur cruel, mais surtout leur propre échec qui les fait appeler constamment à la vengeance et à la révolte. En ce sens, la poésie épique serbe de l’époque de la domination turque n’est qu’une longue épopée sur un thème unique : la liberté.Persuaded that epic Serbian poetry plays an exceptional part in the formation of the language itself as well as in the constitution of a national identity and collective memory, Vuk Karadjich hurries throughout his life to meet traditional epic-singers and note down their poems. It is in this way he is able to collect around one thousand popular songs.Vuk Karadjich

    Full Text Available The process of disintegration of the Yugoslav state was accompanied by social constructs in regard to the Other. Stereotypes, prejudices and stigmas, which had existed during the socialist period, were multiplied during the transitional and especially during the war period. The symbolic imagery was especially burdened by national/nationalist constructions of the reality in the former Yugoslav socio-political area, including in Croatia. In this context, national identity was forcefully activated, as a replacement for socialist ideology. Favourising ethno-national identity over all other sub-identities in the socio-political and symbolic area, and the prevalence of an ethnic model of the nation, suppressed democratic processes, and an authoritative national state came into effect on the public scene. A cultural and socio-psychological atmosphere was created that was conducive to the activation of ethnic/national stereotypes, prejudices, and subsequently to the stigmatisation of Others. In Croatia, images of “ustaše” and “chetniks” were activated in the symbolic and practical-political sphere, which only increased the mutual stigmatisation of Croats and Serbs. Various protagonists during the war conflicts activated symbolic images for their own (often very different goals, and the extent of misuse of national contents depended on the legitimacy or non-legitimacy of political goals, as well as on the behaviour of political and military organisations and of individuals towards Others in given situations. The author’s empirical research, conducted in West and East Slavonia, Banija and Dalmatia among populations of indigenous Croats and Serbs and immigrants, indicates that the stigmatisation of the nationally Other is still largely present in the post-war period. It gained intensity during the war and reached a maximum in the post-war period. All this aggravates the (reconstruction of local communities in former war areas. The gradual

    2013-01-01

    Full Text Available In his prose works, Janićije Popović presented the ethno-psychological heritage of the Serbs in Kosovo and Metohija under the Turkish rule. The author, born in Gračanica, was educated in Bitolj, where his teacher, Milan Gajić, was the first to notice his talent for writing. He recorded the social and historical situation in the Old Serbia, under the Turkish rule. His prose works cover the period between 1812 and 1912. In view of the constant Turkish oppression of the Serbian population in this territory and the so-called 'rayah mentality' which, according to Jovan Cvijić, was formed in these peculiar living conditions, the paper is concerned with the forms of the traditional heritage preserving the archetypal patterns of the ancestors. The writings of Janićije Popović depict the customs of the people from Kosovo, particularly the weddings, Family Saint's Day, folk gatherings, as well as architecture, style of clothing and other forms of everyday life. Janićije Popović provided valuable information on the life of the Serbs under the Turkish rule on the eve of the Balkan wars. The importance of the traditional heritage for preservation of the identity is particularly seen in the forms of collective consciousness which are the subject of our study.

    Full Text Available The paper presents immediate results of a multidisciplinary research into ethno genesis, that is, the origin of the Serbs and the Serbian population, based on genetic indicators. The most direct results of the carried out survey are 85 haplotypes with 17 DYS markers/locuses of the respondents from Aleksandrovac district, a representative area as it is in the very centre of Serbian, Kosovo-Resava linguistic and cultural zone. Unlike previous texts that the authors have written on this subject, this paper, for the first time, presents actual results which correlate ethnological facts - starting from older up to latest records on origin - with genetic results obtained owing to the cooperation of the SASA Institute of Ethnography and the Laboratory for DNA analysis of the National forensic centre at the Ministry of Interior, Republic of Serbia. In this way, new findings, which could have been summoned only by parallel use of ethnological and genetic information (and which are given in the paper as clear proofs of necessity and effectiveness of the applied methodological approach, are being obtained and presented. Among other things, the given results of the preliminary survey (compared with the latest relevant surveys by other authors and institutions indicate the dominance of 12a and R1a haplogroups, decisive in the ethnogenesis of the Slavs, which matches common Serbian perception of the Serbs as of a nation of the Slav language and origin.

    Full Text Available The Slavs do not consider bread to be a common foodstuff, but a sacred object, a symbol of wealth and happiness. Almost all significant rituals (holidays, rites from the life cycle of a person, occasional magical activities use bread. In some of them, such as marriages or the Serbian holiday krsna slava, it is the main ritual object, which has great symbolic value. This paper addresses the use of bread in the ritual behavior of the Serbs and related peoples, where bread has the characteristics of a symbol and therefore gains a communicative function (it is used to convey or to receive information. It is also points out that the symbolic function of bread changes depending on the grain used to make it, whether it is leavened or unleavened, and the shape of it.

    A bench-scale biotreatability methodology was designed to assess field bioremediation of petroleum contaminated soil samples. This methodology was performed successfully on soil samples from more than 40 sites. The methodology is composed of two phases, characterization and experimentation. The first phase is physical, chemical, and biological characterization of the contaminated soil sample. This phase determines soil parameters, contaminant type, presence of indigenous contaminant-degrading bacteria, and bacterial population size. The second phase, experimentation, consists of a respirometry test to measure the growth of microbes indirectly (via generation of CO 2 ) and the consumption of their food source directly (via contaminant loss). Based on a Monod kinetic analysis, the half-life of a contaminant can be calculated. Abiotic losses are accounted for based on a control test. The contaminant molecular structure is used to generate a stoichiometric equation. The stoichiometric equation yields a theoretical ratio for mg of contaminant degraded per mg of CO 2 produced. Data collected from the respirometry test are compared to theoretical values to evaluate bioremediation feasibility

    Full Text Available The paper aims at presenting the current ethno linguistic situation in four Orthodox Serbian villages in the Bela Krajina region of Slovenia. Ethno linguistic material collected in these villages enables the synchronic state of traditional culture to be established. Special attention is payed to the way the interviewees describe Christmas rituals and interpret and evaluate then-present state; apart from description of Christmas interviewees' statements (here named ethno linguistic texts also carry precious information about attitudes of carriers of a certain culture towards its values, and indicate in- and out-group relations, establishing oppositions such as then vs. now, me vs. them, us vs. them. These subjective comments provided by the interviewees help obtain a complete, multilevel picture of a traditional culture, with all interactions that characterize it, both within the ethno linguistic community and in relation to other communities. It is especially important that these interactions be taken into account for isolated ethnic and linguistic groups such as the Orthodox Serbs in Bela Krajina.

    Microbial Fuel Cell (MFC) was developed which was able to generate bio energy continuously while consuming wastewater containing organic matters. Even though the bio energy generated is not as high as hydrogen fuel cell, the MFC demonstrated great potential in bio-treating wastewater while using it as fuel source. Thus far, the dual-ability of the MFC to generate bio energy and bio-treating organic wastewater has been examined successfully using synthetic acetate and POME wastewaters. (author)

Objective: The aim of this study was to treat air containing triethylamine (TEA vapor using biotrickling filter inoculated with microbial species decomposing TEA. Methods: This experimental study was conducted in the School of Health affiliated to Qazvin University of Medical Sciences in 2014. Biotreatment was performed with biotrickling filter inoculated with microbial species decomposing TEA for two months. The biotrickling filter was set up with air containing TEA as the sole source of carbon, at Empty Bed Residence Times (EBRT of 36 sec, and inlet concentration of 84 ppm. Data were analyzed using descriptive statistics. Findings: Treatment of TEA contaminated air was made after an adaptation period of 11 days. Despite an increase in mass loading to 111 g/m3/h, TEA was eliminated with 109 g/m3/h capacity and 94-100% removal efficiency by zero order kinetics.Elimination capacity and removal efficiency were close to each other and confirmed109 g/m3/h as loading region with critical elimination capacity. Conclusion: With regards to the results, it is possible to treat air containing TEA vapor in biotrickling filter.

    2010-01-01

    Full Text Available This work views the relationship between humanitarian actions and ethnic distance in the example of Greeks and Serbs nowadays. There is an issue of a motive and a role of ethnic distance in the manner of conveying humanitarian help, as well as its wider social consequences. The activities of two organizations are taken as an example: the Red Cross and the Greek Caravan of Solidarity. During wars on the territory of Yugoslavia in the 1990s the Red Cross of Serbia was included in an action with the aim of enabling the continuation of education for the children from the war stricken parts. Many other organizations were also included in giving help. The work of the Greek Caravan of Solidarity as an institution which has a specific method of giving help is viewed here. Apart from extenuating the children's war traumas, the numerous gifts and hospitality over the years brought to the deepening of ethnic closeness. Among other things, the expansion of Greek language and culture came as a result of this. The hospitality and friendship have been continued after the war until today.

    Aeromonas veronii GRI (KF964486), isolated from acclimated textile effluent after selective enrichment on azo dye, was assessed for methyl orange biodegradation potency. Results suggested the potential of this bacterium for use in effective treatment of azo-dye-contaminated wastewaters under static conditions at neutral and alkaline pH value, characteristic of typical textile effluents. The strain could tolerate higher doses of dyes as it was able to decolorize up to 1000 mg/l. When used as microbial surfactant to enhance methyl orange biodecolorization, Bacillus subtilis SPB1-derived lipopeptide accelerated the decolorization rate and maximized slightly the decolorization efficiency at an optimal concentration of about 0.025%. In order to enhance the process efficiency, a Taguchi design was conducted. Phytotoxicity bioassay using sesame and radish seeds were carried out to assess the biotreatment effectiveness. The bacterium was able to effectively decolorize the azo dye when inoculated with an initial optical density of about 0.5 with 0.25% sucrose, 0.125% yeast extract, 0.01% SPB1 biosurfactant, and when conducting an agitation phase of about 24 h after static incubation. Germination potency showed an increase toward the nonoptimized conditions indicating an improvement of the biotreatment. When comparing with synthetic surfactants, a drastic decrease and an inhibition of orange methyl decolorization were observed in the presence of CTAB and SDS. The nonionic surfactant Tween 80 had a positive effect on methyl orange biodecolorization. Also, studies ensured that methyl orange removal by this strain could be due to endocellular enzymatic activities. To conclude, the addition of SPB1 bioemulsifier reduced energy costs by reducing effective decolorization period, biosurfactant stimulated bacterial decolorization method may provide highly efficient, inexpensive, and time-saving procedure in treatment of textile effluents.

    The drilling and operation of gas/petroleum exploratory wells and the operations of natural gas and petroleum production wells generate a number of waste materials that are usually stored and/or processed at the drilling/operations site. Contaminated soils result from drilling operations, production operations, and pipeline breaks or leaks where crude oil and petroleum products are released into the surrounding soil or sediments. In many cases, intrinsic biochemical remediation of these contaminated soils is either not effective or is too slow to be an acceptable approach. This project targeted petroleum-impacted soil and other wastes, such as soil contaminated by: accidental release of petroleum and natural gas-associated organic wastes from pipelines or during transport of crude oil or natural gas; production wastes (such as produced waters, and/or fuels or product gas). Our research evaluated the process designated Chemically-Accelerated Biotreatment (CAB) that can be applied to remediate contaminated matrices, either on-site or in situ. The Gas Technology Institute (GTI) had previously developed a form of CAB for the remediation of hydrocarbons and metals at Manufactured Gas Plant (MGP) sites and this research project expanded its application into Exploration and Production (E&P) sites. The CAB treatment was developed in this project using risk-based endpoints, a.k.a. environmentally acceptable endpoints (EAE) as the treatment goal. This goal was evaluated, compared, and correlated to traditional analytical methods (Gas Chromatography (GC), High Precision Liquid Chromatography (HPLC), or Gas Chromatography-Mass Spectrometry (CGMS)). This project proved that CAB can be applied to remediate E&P contaminated soils to EAE, i.e. those concentrations of chemical contaminants in soil below which there is no adverse affect to human health or the environment.

    Availability of quality-certified water is pertinent to the production of food and pharmaceutical products. Adverse effects of manganese content of water on the corrosion of vessels and reactors necessitate that process water is scrutinized for allowable concentration levels before being applied in the production processes. In this research, optimization of the adsorption process conditions germane to the removal of manganese from biotreated palm oil mill effluent (BPOME) using zeolite 3A subsequent to a comparative adsorption with clinoptilolite was studied. A face-centered central composite design (FCCCD) of the response surface methodology (RSM) was adopted for the study. Analysis of variance (ANOVA) for response surface quadratic model revealed that the model was significant with dosage and agitation speed connoting the main significant process factors for the optimization. R(2) of 0.9478 yielded by the model was in agreement with predicted R(2). Langmuir and pseudo-second-order suggest the adsorption mechanism involved monolayer adsorption and cation exchanging.

    A series of environmental programs were initiated at a former petroleum tank site on the west channel of the Mackenzie River following concerns of fuel odours in the soil. A biotreatability study was conducted for the silty soil contaminated with Arctic diesel fuel. The treatment included a bioslurry test that could quickly determine the hydrocarbon biodegradation endpoint under optimum conditions. The treatment also involved a modified soil pan test to monitor real-time oxygen uptake. The test included abiotic, control, nutrient-amended and nutrient/high moisture treatments. CCME and USEPA methods were used to analyze for petroleum hydrocarbons. The response of the bacterial community to different treatments was also examined. Higher degradation rates were observed in the soil pan test than in the slurry test, despite optimum conditions of the slurry test. Higher than expected volatile losses also occurred, suggesting that bioremediation may be possible in the field. These initial field pilot-scale studies offer insight into the challenges of remediating diesel contaminated soils in cold climates. 6 tabs., 6 figs.

    Several biotreatmemt techniques for sulfate conversion by the sulfate reducing bacteria (SRB) have been proposed in the past, however few of them have been practically applied to treat sulfate containing acid mine drainage (AMD). This research deals with development of an innovative polypropylene hollow fiber membrane bioreactor system for the treatment of acid mine water from the Berkeley Pit, Butte, MT, using hydrogen consuming SRB biofilms. The advantages of using the membrane bioreactor over the conventional tall liquid phase sparged gas bioreactor systems are: large microporous membrane surface to the liquid phase; formation of hydrogen sulfide outside the membrane, preventing the mixing with the pressurized hydrogen gas inside the membrane; no requirement of gas recycle compressor; membrane surface is suitable for immobilization of active SRB, resulting in the formation of biofilms, thus preventing washout problems associated with suspended culture reactors; and lower operating costs in membrane bioreactors, eliminating gas recompression and gas recycle costs. Information is provided on sulfate reduction rate studies and on biokinetic tests with suspended SRB in anaerobic digester sludge and sediment master culture reactors and with SRB biofilms in bench-scale SRB membrane bioreactors. Biokinetic parameters have been determined using biokinetic models for the master culture and membrane bioreactor systems. Data are presented on the effect of acid mine water sulfate loading at 25, 50, 75 and 100 ml/min in scale-up SRB membrane units, under varied temperatures (25, 35 and 40 degrees C) to determine and optimize sulfate conversions for an effective AMD biotreatment. Pilot-scale studies have generated data on the effect of flow rates of acid mine water (MGD) and varied inlet sulfate concentrations in the influents on the resultant outlet sulfate concentration in the effluents and on the number of SRB membrane modules needed for the desired sulfate conversion in

    In this article, the current status of membrane bioreactor (MBR) technology for wastewater treatment is reviewed. Fundamental facets of the MBR process and membrane and process configurations are outlined and the advantages and disadvantages over conventional suspended growth-based biotreatment are briefly identified. Key process design and operating parameters are defined and their significance explained. The inter-relationships between these parameters are identified and their implications discussed, with particular reference to impacts on membrane surface fouling and channel clogging. In addition, current understanding of membrane surface fouling and identification of candidate foulants is appraised. Although much interest in this technology exists and its penetration of the market will probably increase significantly, there remains a lack of understanding of key process constraints such as membrane channel clogging, and of the science of membrane cleaning.

  12. A contribution to the vampire studies among Serbs or vampire stories from Luznica

    Full Text Available This paper is the result of original fieldwork performed in the village of Strelac, in southeast Serbia during August 2003. All Slavs believed in the existence of a vampire; still today, this belief is widespread among Serbs. According to the folk stories, a man can become a vampire during his life or after death. It is believed that certain persons have a predisposition to become vampires: informants argued that the condition could descend by inheritance, or if an animal steps over a deceased person. A man can also become a vampire during his lifetime if he suffers from certain illness, but does not take medications, or if, when ill, he is left alone or abandoned by his family. In most cases a vampire hunts his relatives or neighbors, or disturbs their cattle. A vampire makes noise, troubles its relatives, jumps on their back, and sometimes sucks their blood. There are two ways of protection against a vampire: to scold and push a vampire away, and to face the creature in order to "speak out". The "speak-out" method means that a vampire needs to be told about everything it did as a vampire. If a vampire is a vampire-deceased, it is possible to "lure" it with round bread, and banish it from the village. The villagers here use "vampire's bone" for this purpose. These beliefs encourage people to take care of their sick - the ones who do not do so get frequent visits from a vampire.

    A new approach for remediation processes in highly polluted environments is presented. The efficiency of algal-bacterial associations for the remediation of industrial wastewater of a pond in Samara, Russia, was investigated. After screening of algae and bacteria for the resistance to the wastewater the following strains were selected: the algal strains Chlorella sp. ES-13, Chlorella sp. ES-30, Scenedesmus obliquus ES-55, several Stichococcus strains (ES-19, ES-85, ES-86, ES-87, ES-88), and Phormidium sp. ES-90 and the bacterial strains Rhodococcus sp. Ac-1267, Kibdelosporangium aridum 754 as well as two unidentified bacterial strains (St-1, St-2) isolated from the collector pond. All the strains listed above were immobilized onto various solid carriers (capron fibers for algae; ceramics, capron and wood for bacteria) and used for biotreatment in a pilot installation. The results showed that the selected algae and bacteria formed stable consortia during the degradation of the waste, which was demonstrated for the first time for the green alga Stichococcus. Stichococcus and Phormidium cells attached to capron fibers with the help of slime and formed a matrix. This matrix fixed the bacteria and eukaryotic algae and prevented them from being washed off. A significant decrease in the content of the pollutants was observed: phenols were removed up to 85 %, anionic surface active substances (anionic SAS) up to 73 %, oil spills up to 96 %, copper up to 62 %, nickel up to 62 %, zinc up to 90 %, manganese up to 70 %, and iron up to 64 %. The reduction of the biological oxygen demand (BOD{sub 25}) and the chemical oxygen demand COD amounted to 97 % and 51 %, respectively. (Abstract Copyright [2004], Wiley Periodicals, Inc.)

    This paper reports on the combined solar photo-Fenton/biological treatment of an industrial effluent (initial total organic carbon, TOC, around 500 mg L -1 ) containing a non-biodegradable organic substance (α-methylphenylglycine at 500 mg L -1 ), focusing on pilot plant tests performed for design of an industrial plant, the design itself and the plant layout. Pilot plant tests have demonstrated that biodegradability enhancement is closely related to disappearance of the parent compound, for which a certain illumination time and hydrogen peroxide consumption are required, working at pH 2.8 and adding Fe 2+ = 20 mg L -1 . Based on pilot plant results, an industrial plant with 100 m 2 of CPC collectors for a 250 L/h treatment capacity has been designed. The solar system discharges the wastewater (WW) pre-treated by photo-Fenton into a biotreatment based on an immobilized biomass reactor. First, results of the industrial plant are also presented, demonstrating that it is able to treat up to 500 L h -1 at an average solar ultraviolet radiation of 22.9 W m -2 , under the same conditions (pH, hydrogen peroxide consumption) tested in the pilot plant

    The oxidative treatment characteristics of biotreated textile-dyeing wastewater and typical chemicals such as desizing, scouring, dispersing and swelling agents used in the textile-dyeing process by advanced oxidation process were experimentally studied. The refractory organic matters remained in the effluent of biological treatment process without degradation may be suitable for the improvement of biodegradability and mineralized to CO2 by combined ozonation with and without hydrogen peroxide. On the other hand, the refractory chemicals contained in the scouring agent A and swelling agent may not be mineralized and their biodegradability may not be improved by ozonation. However, the BOD/DOC ratio of scouring agent B increased from 0.3 to 0.45 after ozonation. Based on the results described above, advanced treatment process involving the ozonation without and with the addition of hydrogen peroxide, followed by biological treatment was proposed for the treatment of refractory wastewater discharged from the textile-dyeing process.

    Full Text Available Potato liquor, a byproduct of potato starch production, is steam-treated to produce protein isolate. The heat treated potato liquor (HTPL, containing significant amounts of organic compounds, still needs to be further treated before it is discarded. Presently, the most common strategy for HTPL management is concentrating it via evaporation before using it as a fertilizer. In this study, this scenario was compared with two biotreatments: (1 fermentation using filamentous fungus R. oryzae to produce a protein-rich biomass, and (2 anaerobic digestion of the HTPL to produce biogas. Technical, economic and environmental analyses were performed via computational simulation to determine potential benefits of the proposed scenarios to a plant discarding 19.64 ton/h of HTPL. Fungal cultivation was found to be the preferred scenario with respect to the economic aspects. This scenario needed only 46% of the investment needed for the evaporation scenario. In terms of the environmental impacts, fungal cultivation yielded the lowest impacts in the acidification, terrestrial eutrophication, freshwater eutrophication, marine eutrophication and freshwater ecotoxicity impact categories. The lowest impact in the climate change category was obtained when using the HTPL for anaerobic digestion.

While German woman came during Milošević’s regime in 1999, the British woman came in 2002. Although they did not suffer from “professional deskilling”, which is typical for female migration in general, they both had to prequalify in order to find a job in Serbia. However, they both found it was easier to regulate their residence status through family, not working, visa, especially before new legal documents concerning foreigners’ status were introduced. For instance, the most important legal document adopted as part of EU-integration process are Law on Foreigners (2008, Law on Migration Management (2012 and Law on Employment and Work of Foreign Citizens (2014. Foreigners living in Serbia represent the important group as many of them either work or use their pensions in Serbia.

    Full Text Available From the aspect of contributions of true reformers Dr Đorđe Natošević, Aleksandar Demetrović, Dr Tihomir Ostojić, Pavle Miljušević, and Gligorije Mirković, secondary school education of the Serbs in Vojvodina until 1914, represents a specific recollection of the pedagogical thought in terms of “future”. It is not for no reason that focusing on the contribution of certain individuals i.e. torchbearers of the modern physical education today, especially tomorrow, sets us apart from misfortunes of those who “do not know what they want” and catastrophe of those who “do not know what they can do”. Today, as once used to be the case with Vienna, Dresden and Bučarov’s Zagreb, we need a source of new European ideas, as well as awareness that “balance” within the divided world can be found in the works of seductive East, especially in the achievements of our own people. It is for this very reason that the Serbian intelligence, which is being taught warning lessons about superficiality and uninterestedness of even the most educated ones, is responsible towards future generations to follow the “track of the past” in order to find new sense on frequently imposed paths. In this direction, it is doubtlessly difficult to recognize the place and role of politics, economy, culture and least of all physical culture and education as a whole, however, one cannot deny the fact that the 19th and 20th centuries spread the “fog” in which it is difficult to “distinguish” the relations between global and national goals, modern and traditional attitudes, pleasure of squandering and creativity of work.

    The presence of micropollutants in sewage is already widely known, as well as the effects caused by natural and synthetic hormones. Thus, it is necessary to apply treatments to remove them from water systems, such as advanced oxidation processes (AOPs) and membrane separation processes, which can oxidize and remove high concentrations of organic compounds. This work investigated the removal of 17β-estradiol (E2), 17α-ethinylestradiol (EE2), and estriol (E3) from biotreated sewage. Reverse osmosis processes were conducted at three recoveries (50, 60, and 70 %). For E2 and EE2, the removals were affected by the recovery. The best results for RO were as follows: the E2 compound removal was 89 % for 60 % recovery and the EE2 compound removal was 57 % for 50 % recovery. The RO recovery did not impact the E3 removal. It was concluded that the interaction between the evaluated estrogens, and the membrane was the major factor for the hormone separation. The AOP treatment using H 2 O 2 /UV was carried out in two sampling campaigns. First, we evaluated the variation of UV doses (24.48, 73.44, 122.4, and 244.8 kJ m -2 ) with 18.8 mg L -1 of H 2 O 2 in the reaction. EE2 showed considerable removals (around 70 %). In order to optimize the results, an experimental design was applied. The best result was obtained with higher UV dose (122.4 kJ m -2 ) and lower H 2 O 2 concentration (4 mg L -1 ), achieving removal of 91 % for E3 and 100 % for E2 and EE2.

    GAC/O3 (ozonation in the presence of granular activated carbon) combined with enhanced coagulation was employed to process biotreated textile wastewater for possible reuse. The doses of ozone, GAC and coagulant were the variables studied for optimization. The effects of different treatment processes on effluent organic matter (EfOM) characteristics, including biodegradability, hydrophobic and hydrophilic nature, and apparent molecular weight (AMW) distribution were also investigated. Compared with ozonation, GAC/O3 not only presented a higher pre-oxidation efficiency, but also improved the treatability of hydrophobic and high molecular weight compounds by enhanced coagulation. After treatment by GAC/O3 pre-oxidation (0.6 mg O3 x mg(-1) COD and 20 g x L(-1) GAC) and enhanced coagulation (25 mg x L(-1) Al3+ at pH 5.5), the removal efficiencies of chemical oxygen demand (COD), dissolved organic carbon (DOC) and colour were higher than those for coagulation alone by 17.3%, 12.0% and 25.6%, respectively. Residual organic matter consisted mainly of hydrophobic acids and hydrophilic compounds of AMW wastewater.

    More than 1,500 MGP (manufactured gas plant) sites exist throughout the US. Many are contaminated with coal tar from coal-fueled gas works which produced ''town gas'' from the mid-1800s through the 1950s. Virtually all old US cities have such sites. Most are in downtown areas, as they were installed for central distribution of manufactured gas. While a few sites are CERCLA/Superfund, most are not. However, the contaminants and methods used for remediation are similar to those used for Superfund cleanups of coal tar contamination from wood-treating and coke oven facilities. Clean-up of sites is triggered by property transfers and re-development as well as releases to the environment--in particular, via ground water migration. This paper describes recent experience with high capacity/low cost thermal desorption process for this waste. It also reviews competing non-thermal technology, such as bio-treatment, capping, recycling, and dig and haul. Cost data are provided for all technologies, and a case study for thermal treatment is also presented

    Objectives. This study assessed patterns of displacement and human rights abuses among Kosovar refugees in Macedonia and Albania. Methods. Between April 19 and May 3, 1999, 1180 ethnic Albanian refugees living in 31 refugee camps and collective centers in Macedonia and Albania were interviewed. Results. The majority (68%) of participants reported that their families were directly expelled from their homes by Serb forces. Overall, 50% of participants saw Serb police or soldiers burning the houses of others, 16% saw Serb police or soldiers burn their own home, and 14% witnessed Serb police or soldiers killing someone. Large percentages of participants saw destroyed mosques, schools, or medical facilities. Thirty-one percent of respondents reported human rights abuses committed against their household members, including beatings, killings, torture, forced separation and disappearances, gunshot wounds, and sexual assault. Conclusions. The present findings confirm that Serb forces engaged in a systematic and brutal campaign to forcibly expel the ethnic Albanian population of Kosovo. In the course of these mass deportations, Serb forces committed widespread abuses of human rights against ethnic Albanians. PMID:11726386

    Full Text Available All steps in the rice vermicelli production discharged a big volume of wastewater containing significant amount of starch and sugar, except rice soaking. During the microbiological treatment, its known that starch, sugar or other carbon hydrates were disintegrated and transformed into finally simple molecular such as methane, carbon dioxide and water. But how is it happened is a question need to be further investigated. The result of this work partly showed out that, in the aerobic biotreatment process, starch and sugar concentration was continuously decreased in unchanged pH value during the treatment process. This counted that there was the biodegradation overwhelmed. The concentration of starch and sugar in biomass was sharply increased at the beginning hours was determined as a result of adsorption of organic matter on the biomass. However, in the anaerobic process, the variation of starch and sugar concentration was more complicated. The increase of sugar concentration in acidic phase was considered as a result of the chemical hydrolysis beside biodegradation of the starch. In this very work, in the different stages of treatment processes, the disintegration rates of starch and sugar were determined and their distribution in the solution and in the biomass during the treatment processes was discussed.

  7. Effects of bacterially produced precipitates on the metabolism of sulfate reducing bacteria during the bio-treatment process of copper-containing wastewater

    A large volume of bacterially produced precipitates are generated during the bio-treatment of heavy metal wastewater.The composition of the bacterially produced precipitates and its effects on sulfate reducing bacteria (SRB) in copper-containing waste stream were evaluated in this study.The elemental composition of the microbial precipitate was studied using electrodispersive X-ray spectroscopy (EDX),and it was found that the ratio of S:Cu was 1.12.Combining with the results of copper distribution in the SRB metabolism culture,which was analyzed by the sequential extraction procedure,copper in the precipitates was determined as covellite (CuS).The bacterially produced precipitates caused a decrease of the sulfate reduction rate,and the more precipitates were generated,the lower the sulfate reduction rate was.The particle sizes of bacterially generated covellite were ranging from 0.03 to 2 m by particles size distribution (PSD) analysis,which was smaller than that of the SRB cells.Transmission electron microscopy (TEM) analysis showed that the microbial covellite was deposited on the surface of the cell.The effects of the microbial precipitate on SRB metabolism were found to be weakened by increasing the precipitation time and adding microbial polymeric substances in later experiments.These results provided direct evidence that the SRB activity was inhibited by the bacterially produced covellite,which enveloped the bacterium and thus affected the metabolism of SRB on mass transfer.

    Full Text Available The paper examines conjunctive and disjunctive social integrational processes (cooperation and conflict in the western part of the Brod-Posavina county. The actors involved in the mentioned processes – queried in a questionnaire survey – included refugees-immigrants, returnee Croats, returnee Serbs and representatives of the institutions of the groups. In total, 180 war victims were surveyed. With the end of the war, the primary network of social relations in the liberated area is beginning to be renewed. At first after the return especially of Serbs there were conflicts and settlings of accounts between the members of the three groups of war victims. However, although the conflicts were present on the level of nationality (which is not surprising in view of the Serb aggression on Bosnia and Herzegovina and Croatia and the marked stigmatisation of this national group, a shift can be noted from the psycho-emotional to the socio-economical levels. Although there is enmity in Croat–Serb relations, nevertheless the conflict is more pronounced between refugees-immigrants and returnee Serbs, despite what might be expected on the basis of the war events. Yet as opposed to returnee Croats, refugees-immigrants were not actors of the war events in this area, which may be (on the psychological level a slight advantage in communicating with returnee Serbs. However, among them as well it is evident that conflicts occur mainly in the area of property, which is precisely the unresolved question between refugees-immigrants and returnee Serbs. Immigrants from Bosnia and Herzegovina have been settled mainly in houses of persons of Serb nationality, which is the source of intolerance, distrust as well as conflict between them. On the other hand, returnee Croats are relatively secure in this regard and do not have direct property relations with the Serb population. Memories of the war and the role of the Serbs is not negligible, but it is also noted that the

    Fresh leachate from municipal solid waste (MSW) incineration plants generally contains extremely high NH4(+)-N concentration which could inhibit the bioactivity of microorganisms. The inhibitory effect of high NH4(+)-N concentration on anaerobic biotreatment of fresh leachate from a MSW incineration plant in China has been investigated in this study. The inhibition processes was studied by both static tests and a laboratory-scale expanded granular sludge bed (EGSB) reactor. The specific methanogenic activity (SMA) of the microorganisms in anaerobic granular sludge was inhibited with the NH4(+)-N concentration increasing to 1000mg/L in static tests. As well the chemical oxygen demand (COD) removal efficiency and the methane yield decreased in the EGSB reactor, while the volatile fatty acids (VFAs) accumulated and extracellular polymeric substances (EPS) of the anaerobic granular sludge increased with NH4(+)-N concentration rising to 1000mg/L, without any rebounding during 30days of operation. Decreasing NH4(+)-N concentration to 500mg/L in influent, the COD removal efficiency recovered to about 85% after 26days. 1000mg/L of NH4(+)-N in leachate was suggested to be the inhibition threshold in EGSB reactor. High-throughput sequencing results showed little changes in microbial communities of the sludge for a high NH4(+)-N concentration, indicating that the survival of most microorganisms was not affected under such a condition. It inhibited the bioactivity of the microorganisms, resulting in decrease of the COD removal efficiency. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available This paper looks at Nikola Pašić’s views of and contribution to the foreign policy of the Kingdom of Serbs, Croats and Slovenes (SCS/Yugoslavia after1929 during the latest phase of his political career, a subject that has been neglected by historians. His activities in this field are divided into two periods - during the Paris Peace Conference where he was the head of the SCS Kingdom’s delegation and after 1921 when he became Prime Minister, who also served as his own Foreign Minister. During the peace conference, Pašić held strong views on all the major problems that faced his delegation, particularly the troubled delimitation with Italy in the Adriatic. In early 1920, he alone favoured the acceptance of the so-called Lloyd George-Clemenceau ultimatum, believing that the time was working against the SCS Kingdom. The Rapallo Treaty with Italy late that year proved him right. Upon taking the reins of government, Pašić was energetic in opposing the two restoration attempts of Karl Habsburg in Hungary and persistent in trying to obtain northern parts of the still unsettled Albania. In time, his hold on foreign policy was weakening, as King Alexander asserted his influence, especially through the agency of Momčilo Ninčić, Foreign Minister after January 1922. Pašić was tougher that King and Ninčić in the negotiations with Mussolini for the final settlement of the status of the Adriatic town of Fiume and the parallel conclusion of the 27 January 1924 friendship treaty (the Pact of Rome. Since domestic politics absorbed much of his time and energy, the old Prime Minister was later even less visible in foreign policy. He was forced to resign in April 1926 on account of his son’s corruption scandal shortly before the final break-down of relations with Italy.

    Bioremediation technologies are focused to the biodegradation of organic pollutants. This approach is particularly helpful when soils and/or groundwater are affected by oil products spills, given the satisfactory biodegradability of most hydrocarbons. However, during a bio-treatment the decreasing in pollutants concentration may be due to both biotic and biotic processes, whose distinction is very important, albeit difficult, in order to evaluate if bioremediation is being properly applied.

    Solar disinfection (SODIS) of urban wastewater can be a suitable technology for improving the microbiological quality of reclaimed water as a complement to other extensive and environmentally friendly technologies such as microalgae biotreatment. The objective of this work is to evaluate the feasibility of incorporating the SODIS technology at the end of a pilot scale urban wastewater treatment plant (WWTP) where the processes are based on microalgae biotechnology and comprising three Upflow Anaerobic Sludge Blanket (UASB, 20m 3 each one) reactor, six High Rate Algal Ponds (HRAP, 32m 2 each one), and a Dissolved Air Flotation (DAF, 1m 3 ) unit. E. coli concentration was monitored at the effluent of the different units (UASB, HRAP, DAF) of the pilot WWTP. The efficiency of the SODIS process was studied for the inactivation of three of the commonly employed indicator microorganisms (Escherichia coli, Enterococcus spp. and Clostridium perfringens) using a compound parabolic collector (CPC) for five months under various conditions of irradiance and temperature. E. coli and Enterococcus spp. were more effectively disinfected by the SODIS unit (2.9 and 2.5 logarithms of reduction on average, respectively) than by the HRAP (2 and 1.1) or the DAF (0.9 and 0.1). On the contrary, the DAF technology achieved better reduction rates of C. perfringens (1.7) than the SODIS (0.9) and the HRAP (0.1). No regrowth of any microorganisms was detected during dark storage after the SODIS treatment. Incorporating a SODIS unit after the non-conventional WWTP processes substantially increases the possibilities for reuse of the treated water after receiving a cumulative UV radiation dose of 25W·h/m 2 (50min of normalized time of solar illumination). The surface requirement of the SODIS equipment would be 3.5 times smaller than the HRAP's surface. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of the present study was to study the performance of bio-treatment ponds after one year of functioning at National Agricultural Research Center, Islamabad, Pakistan. The physical parameters (colour, pH, EC, TDS, turbidity) and chemical parameters (Zn, Cu, Cd, Ni, Mn, Fe and Pb) are with in the limits which are not sub-lethal for fish rearing. Lemna accumulates higher concentration of heavy metals as compared to wastewater and best for phyto remediation purpose. The treated wastewater is currently used for rearing of fish and irrigation of crops and plants. The plants around the bio-treatment ponds are healthy, green and showing enough production. The present investigation indicates that in future it would be possible to construct bio-treatment ponds in polluted areas of Pakistan. (author)

    Full Text Available In this article foundations of antiserbian propaganda in euro-american media in the nineties are widely discussed. In the main pattern it was copy of old Austro-Hungarian and Comminterian antiserbian propaganda procedures. In keeping with this procedures Slovenian and Croats, and lately Albanians, are connected with positive values identified with Good, and Serbs with negative ones, identified with Evil. Thus, justification for disintegration of Yugoslavia were provided with main move to accuse Serbs and Serbia for it. Key of such a propaganda could be find in Carl Schmitt's friend-foe dualism which contains moral oppositions good-evil, esthetic beauty-ugly, and economic useful-harmful. Therefore, Serbs in euro-american, especially in german press and other media were represented as evil and ugly ones, thus providing justification for humiliating them on the moral plane. .

    More than 1,500 manufactured gas plant (MGP) sites exist throughout the US. Many are contaminated with coal tar from coal-fueled gas works which produced town gas from the mid-1800s through the 1950s. Virtually all old US cities have such sites. Most are in downtown areas as they were installed for central distribution of manufactured gas. While a few sites are CERCLA/Superfund, most are not. However, the contaminants and methods used for remediation are similar to those used for Superfund clean-ups of coal tar contamination from wood-treating and coke oven facilities. Clean-up of sites is triggered by regulatory pressure, property transfers and re-development as well as releases to the environment--in particular, via groundwater migration. Due to utility de-regulation, site clean-ups may also be triggered by sale of a utility or of a specific utility site to other utilities. Utilities have used two approaches in dealing with their MGP sites. The first is do nothing and hope for the best. History suggests that, sooner or later, these sites become a bigger problem via a release, citizen lawsuit or regulatory/public service commission intervention. The second, far better approach is to define the problem now and make plans /for waste treatment or immobilization. This paper describes recent experience with a high capacity/low cost thermal desorption process for this waste and reviews non-thermal technology, such as bio-treatment, capping, recycling, and dig and haul. Cost data are provided for all technologies, and a case study for thermal treatment is also presented

    The Fenton process is used as a tertiary treatment to remove organic pollutants from the effluent of bio-treated pharmaceutical wastewater (EBPW). The optimal and most appropriate Fenton conditions were determined by an orthogonal array test and single-factor experiments. The removal of chemical oxygen demand (COD) was influenced by the following factors in a descending order: H 2 O 2 /Fe(II) molar ratio > H 2 O 2 dosage > reaction time. Under the most appropriate Fenton conditions (H 2 O 2 /Fe(II) molar ratio of 1:1, H 2 O 2 dosage of 120 mg L -1 and reaction time of 10 min), the COD and dissolved organic carbon (DOC) were removed with efficiencies of 62 and 53%, respectively, which met the national discharge standard (GB 21903-2008) for the Lake Tai Basin, China. However, the Fenton treatment was inadequate for removal of N compounds, and the removal of organic nitrogen led to an increment in N-NH 3 from 3.28 to 19.71 mg L -1 . Proteins and polysaccharides were completely removed, and humic acids (HAs) were partly removed with an efficiency of 55%. Three-dimensional excitation/emission matrix spectra (3DEEMs) indicated complete removal of fulvic acid-like substances and 90% reduction in the florescence intensity of humic acid-like substances. Organic pollutants with molecular weights (MW) > 10 kDa were completely removed, MW 5-10 kDa were degraded into smaller MW ones, and some low molecular weight acids (MW 0.1-1 kDa) were mineralized during the Fenton process. Some species, including pharmaceutical intermediates and solvents were detected by gas chromatography-mass spectrometry (GC-MS). The operational costs of the Fenton's treatment were estimated to be 0.58 yuan RMB/m 3 EBPW based on reagent usage and iron sludge treatment and disposal.

  17. The question of autonomy of Bosnia and Herzegovina as Serbian self-defence

    Full Text Available This work discusses the historical struggle of Serbian people in Bosnia and Herzegovina for the autonomous freedom, through numerous rebellions and uprisings in the 19th century, such as rebellions and uprisings of Serbs in Šumadija. After its success in Serbia under the rule of Miloš Obrenović, Serbs' struggle for the autonomous freedom in Bosnia and Herzegovina in the last period of the Ottoman and later Austro-Hungarian authority was a 'categorical imperative of Serbian self defence'. Resistance to foreign occupiers in Bosnia and Herzegovina was repeated after the disintegration of Yugoslavia in 1991, with the struggle for the autonomous freedom in the Republic of Srpska, for its achievements, challenges and perspectives. On both of these occasions, Serbian people remained and fought for their freedom and unity in the community with other nations. On both of these occasions, destiny and outcome of this successful struggle with opponents were earlier in hands of great powers and later in hands of powerful states. Their earlier and later attitudes towards Serbs were different. Compared to Bulgarians and Bulgaria, or Cretans and Crete, after whose uprisings the great powers awarded them the autonomy, they only promised the same to Serbs while some of them opposed it and corrupted, up until the end of the First World War. It was similar with the struggle of Serbs in Bosnia and Herzegovina for freedom in the achieved Republic of Srpska, up until the United States of America took Bosnia and Herzegovina in its own hands. The States, in cooperation with the Contact Group members, ended the civil war in Bosnia and Herzegovina at the meeting in Dayton in the USA in 1995, while at the same time legitimizing the Republic of Srpska within the two-entity Bosnia and Herzegovina.

  18. Illegal Serbian Structures in the Republic of Kosovo Why these structures are illegal and not paralel?

    Full Text Available This paper argues that Serb structures, operating in Kosovo after the forced withdrawal under NATO intervention of Serb-Yugoslav mechanisms of power from Kosovo in June 1999 which marks the end of the war and at the same time the beginning of a new process of peace building, do not represent parallel structures, rather they represent illegal structures. This paper argues that these kinds of structures achieved to be established and being continuesly strengthened due to multi-dimensional support of the Republic of Serbia which for its interest needed them to undermine the establishment of functional governance overall in Kosovo but predominantly in the Serb enclaves, and also due to UN Interim Administration in Kosovo which’s main interest was peace and stability not functionality of governance. In this paper, it is also argued that these Serb structures do not represent the majority of Serbs living in Kosovo because they are incorporated into the constitutional institutions of the Rrepublic of Kosovo. Through comparing main domestic and international documents by which UN Interim Administration and National Institutions of Governance were established and also data gathered in the field through different reports, this paper concludes that: these structures are unconstitutional structures, and therefore illegal, rather than parallel structures; consideration of them as parallel by UN Interim Administration was a mistake which negatively affected integration, development, and democratization of a part of the Serbian community in Kosovo’s northern municipalities; they are also supported by criminal structures which seriously impede the exercise of state power, the legal system, and the development of democracy predominantly in the northern part of Kosovo; and beside of political and diplomatic efforts, a state organized force with an international support is the only answer to criminal structures.

    Low levels (< 1 mg/L) of acetone, cyanide, phenol, naphthalene, 2-methylnaphthalene, and carbon disulfide from an inactive industrial landfill were found above background levels in a shallow aquifer at an eastern coastal site. In situ biodegradation was evaluated for treatment of these contaminants. Two soil samples and three groundwater samples were taken from the site for a laboratory bioassessment and a biotreatability test. The positive results of the bioassessment suggested moving forward with biotreatability testing. Biotreatability test results indicated suitable site conditions for bioremediation and that all the contaminants of concern at the site could be biodegraded to nondetect or very low levels (< 50 microg/L) with oxygen only; i.e., addition of nutrients was not required. Pilot-scale testing was undertaken on site to provide information for full-scale design, including oxygen requirements and air injection well spacing. This report describes the approach, the results, and their impact on the full-scale remediation system

    Highlights: • High NH{sub 4}{sup +}–N concentrations inhibit anaerobic treatment of leachate. • Inhibitory effect of NH{sub 4}{sup +}–N concentrations on anaerobic granular sludge is reversible. • High NH{sub 4}{sup +}–N concentrations inhibit bioactivities of microorganisms instead of survival. - Abstract: Fresh leachate from municipal solid waste (MSW) incineration plants generally contains extremely high NH{sub 4}{sup +}–N concentration which could inhibit the bioactivity of microorganisms. The inhibitory effect of high NH{sub 4}{sup +}–N concentration on anaerobic biotreatment of fresh leachate from a MSW incineration plant in China has been investigated in this study. The inhibition processes was studied by both static tests and a laboratory-scale expanded granular sludge bed (EGSB) reactor. The specific methanogenic activity (SMA) of the microorganisms in anaerobic granular sludge was inhibited with the NH{sub 4}{sup +}–N concentration increasing to 1000 mg/L in static tests. As well the chemical oxygen demand (COD) removal efficiency and the methane yield decreased in the EGSB reactor, while the volatile fatty acids (VFAs) accumulated and extracellular polymeric substances (EPS) of the anaerobic granular sludge increased with NH{sub 4}{sup +}–N concentration rising to 1000 mg/L, without any rebounding during 30 days of operation. Decreasing NH{sub 4}{sup +}–N concentration to 500 mg/L in influent, the COD removal efficiency recovered to about 85% after 26 days. 1000 mg/L of NH{sub 4}{sup +}–N in leachate was suggested to be the inhibition threshold in EGSB reactor. High-throughput sequencing results showed little changes in microbial communities of the sludge for a high NH{sub 4}{sup +}–N concentration, indicating that the survival of most microorganisms was not affected under such a condition. It inhibited the bioactivity of the microorganisms, resulting in decrease of the COD removal efficiency.

    The environmentally safe destruction of pinkwater is a significant problem that requires a multidisciplinary approach to solve. We have investigated the application of advanced oxidation processes, including the use of both UV light source and laser technologies. The reactions were run under both oxidizing and reducing atmospheres. Aerobic and anaerobic biotreatments were examined as both pre- and post-treatments to the oxidation processes. The toxicity of the wastewater at various stages of treatment was determined. Membrane preconcentration schemes were examined to determine their effectiveness as part of the total pinkwater treatment scheme.

    This project focuses on the rapid implementation of near-surface barriers, biotreatment, and post-closure monitoring technology. It uses water-permeable and biologic barriers that chemically capture and/or degrade contaminants without significantly altering the natural water flow regime. Barrier approaches are being tested for two different applications. The first is the use of barriers for confinement of chemical contaminants for in-trench treatments with leach systems or an in-place bioreactor. The second is an enhancement of the current practice of emplacing grout or clay slurry walls into direct horizontal surface and subsurface water flows around a contaminated area by integrating permeable reactive barriers and petroleum reservoir gel/foam/polymer technology

    The authors tested five composite soil samples from a former refinery. The samples included a reference soil (Mineral Oil and Grease, MO and G < 40 ppm), thermally-treated soil, biotreated soil, and two untreated soils. They evaluated toxicity using the earthworm E. foetida, lettuce, cress, barley, Microtox, green algae, fathead minnow, and D. magna. The endpoints measured were lethality, seed germination, root elongation, growth, and bioluminescence. Toxicity, as measured by the number of positive responses, increased as follows: biotreated soil < untreated soil No. 1 < reference soil < thermally-treated soil and untreated soil No. 2. The biotreated soil generated only one positive response, whereas the thermally-treated soil and untreated soil No. 2 generated five positive responses. The most sensitive and discriminant terrestrial endpoint was lettuce root elongation which responded to untreated soil No. 1, thermally-treated soil, and reference soil. The least sensitive was barley seed germination for which no toxicity was detected. The most sensitive and discriminant aquatic endpoint was green algae growth which responded to untreated soil No. 1, thermally-treated soil, and reference soil. The least sensitive was D. magna for which no toxicity was detected. Overall, soil and aqueous extract toxicity was spotty and no consistent patterns emerged to differentiate the five soils. Biotreatment significantly reduced the effects of the contamination. Aqueous toxicity was measured in the reference soil, probably because of the presence of unknown dissolved compounds in the aqueous extract. Finally, clear differences in sensitivity existed among the test species

  4. Spotlight: Bosnia and Herzegovina.

    This article discusses the demographic outcomes of the end of the civil war in Bosnia and Herzegovina. The war ended with the creation of the Bosnian Serb Republic and the Muslim-Croat Federation. In mid-1998, the population was 3.9 million. The population is smaller than it was before 1991, when Slovenia and Croatia separated from Yugoslavia. Many highly educated people left. Unemployment is an estimated 65-75%. Almost 500,000 soldiers must adjust to being civilians. In 1992, Muslims were 38% of total population, and Croats were 22% of total population. Muslims and Croats are now minorities in the Muslim-Croat Federation. The Serbs, who were 40% of the total population, led a civil war that was motivated by the desire for a Serb Republic. The Serbian "ethnic cleansing" created many thousands of refugees. Since the late 1995 Dayton Accord, about 400,000 refugees and displaced persons have returned to their prewar homes. Muslim-Croat Federation areas have received many refugees and have agreed to participate in the UN High Commissioner for Refugees' "open cities" project. About 1.5 million people are still scattered across Bosnia, Croatia, Yugoslavia, and Western Europe. Refugees are guaranteed under the Dayton Accord the right to return to their homes. However, returning means facing the dangers of land mines and other explosives in rural areas and being stoned along major roadways. Travelers rely on a few selected roads. Buses are considered a safe mode of transportation. The Serb Republic still defies the Dayton Accord, opposes the return of minorities, and enforces ethnic separation.

    Pigments in molasses wastewater (MWW) effluent, such as melanoidins, were considered as kinds of the most recalcitrant and hazardous colorant contaminants to the environment. In this study, de-coloring the MWW by a synergistic combination of micro-electrolysis with bio-treatment was performed. Aiming to a high de-colorization yield, levels of nutrition source supplies, MWW dilution ratio, and micro-electrolysis reaction time were optimized accordingly. For a diluted (50 %, v/v) MWW, an maximum overall de-colorization yield (97.1 ± 0.5 %, for absorbance at 475 nm) was achieved through the bio-electrolysis treatment. In electrolysis bio-treatment, the positive effect of micro-electrolysis was also revealed by a promoted growth of fungal biomass as well as activities of ligninolytic enzymes. Activities of lignin peroxidase, manganese peroxidase, and laccase were promoted by 111.2, 103.9, and 7.7 %, respectively. This study also implied that the bio-treatment and the micro-electrolysis had different efficiencies on removal of pigments with distinct polarities.

  6. Serbian crisis: How to reflect about it?

    2008-01-01

    Full Text Available In this article, which is just an initial paper within a few-year-long research, we are trying to identify causes of the crisis which the Serbian state and the Serb people experience - not just in the last few years or decades, but, as we believe, already for centuries. The main problem is Serbs' long-lasting incapability to consolidate both: the national identity and a national state, which is caused by permanent instability of Serbian history, absence of an active attitude toward their own tradition and a lack of notion of self-virtue which dominate the Serbian national "character". There are two main difficulties of the present day Serbian crisis: the fact that our people and their state are not well-fitted to the contemporary world and its civilization, which is, as a matter fact, quite a permanent issue in modern history of the Serbs, as well as the loss of vitality, which in the past at least substituted the poor success in "socialization" in the world ruled by major nations. This dual shortcoming is a very unfavorable prerequisite for facing challenges which are doubtlessly expecting our, to say it with Plessner, "uncompleted nation".

    Contamination in low permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, pump and treat rather ineffective when applied to law permeability soils present at many contaminated sites. The Lasagna technology is an integrated in-situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil and electro-osmosis is utilized to move the contaminants back and forth through those zones until the treatment is completed. The general concept of the technology is to use electrokinetics to move contaminants from the soils into open-quotes treatment zonesclose quotes where the contaminants can be removed from the water by either adsorption or degradation. The focus of technical task No. 7 was to optimize the conditions required for electro-osmotic movement of contaminants and microbial degradation in the treatment zones. This topical report summarizes the results of aerobic microbial research performed to evaluate the feasibility of incorporating the chemical-degrading organisms into biotreatment zones in laboratory-scale electro-osmosis units and to demonstrate the combination of electrokinetics and aerobic microbial degradation for the removal of contaminants from clay. Also included in this report are the results of investigating microbial movement during electro-osmosis and studies involving the optimization of the microbial support matrix in the biozone. The Stanford study was conducted in order to obtain a better understanding of rates of anaerobic reductive dehalogenation of TCE to ethylene and of factors affecting these rates in order to determine the potential for application of TCE biodegradation as part of the Lasagna technology

    Effluent organic matter (EfOM) from municipal wastewater treatment plants potentially has a detrimental effect on both aquatic organisms and humans. This study evaluated the removal and transformation of chromophoric dissolved organic matter (CDOM) and fluorescent dissolved organic matter (FDOM) in a full-scale wastewater treatment plant under different seasons. The results showed that bio-treatment was found to be more efficient in removing bulk DOM (in term of dissolved organic carbon, DOC) than CDOM and FDOM, which was contrary to the disinfection process. CDOM and FDOM were selectively removed at various stages during the treatment. Typically, the low molecular weight fractions of CDOM and protein-like FDOM were more efficiently removed during bio-treatment process, whereas the humic-like FDOM exhibited comparable decreases in both bio-treatment and disinfection processes. Overall, the performance of the WWTP was weak in terms of CDOM and FDOM removal, resulting in enrichment of CDOM and FDOM in effluent. Moreover, the total removal of the bulk DOM (PCDOM and the humic-like FDOM showed little differences between summer and winter. In all, the results provide useful information for understanding the fate and transformation of DOM, illustrating that sub-fractions of DOM could be selectively removed depending on treatment processes and seasonality.

    Within soil ecosystems contaminant toxicity can vary from acute and chronic, depending on the time of exposure. Due to the long times involved chronic toxicity is difficult to determine. DNA adducts fall into the category of biochemical markers that act as an early warning system in environmental monitoring. It has been proposed that they could be used as a sensitive method to determine environmental exposures to compounds such as polycyclic aromatic hydrocarbons (PAHs), which can occur, although not exclusively, in creosote. In this connection, Benzo[a]pyrene (BaP) is a PAH that can be transformed into an electrophilic metabolite, which ultimately results in DNA adduct formation. Use was made of a 32P postlabeling method to quantify the number of DNA adducts occurring in the earthworm Eisenia fetida after exposure to weathered creosote contaminated- and biotreated-soils with and without additions of extra BaP. DNA adducts can be measured in earthworms exposed to creosote contaminated- and biotreated-soils. E. fetida exposed to weathered creosote contaminated soils had significantly more DNA adducts than those exposed to a pristine control soil.

    Poorvasha, S.; Lakshmi, B.

    2018-05-01

    In this paper, RF performance analysis of InAs-based double gate (DG) tunnel field effect transistors (TFETs) is investigated in both qualitative and quantitative fashion. This investigation is carried out by varying the geometrical and doping parameters of TFETs to extract various RF parameters, unity gain cut-off frequency (f t), maximum oscillation frequency (f max), intrinsic gain and admittance (Y) parameters. An asymmetric gate oxide is introduced in the gate-drain overlap and compared with that of DG TFETs. Higher ON-current (I ON) of about 0.2 mA and less leakage current (I OFF) of 29 fA is achieved for DG TFET with gate-drain overlap. Due to increase in transconductance (g m), higher f t and intrinsic gain is attained for DG TFET with gate-drain overlap. Higher f max of 985 GHz is obtained for drain doping of 5 × 1017 cm‑3 because of the reduced gate-drain capacitance (C gd) with DG TFET with gate-drain overlap. In terms of Y-parameters, gate oxide thickness variation offers better performance due to the reduced values of C gd. A second order numerical polynomial model is generated for all the RF responses as a function of geometrical and doping parameters. The simulation results are compared with this numerical model where the predicted values match with the simulated values.

    Full Text Available Intolerance of Vatican primarily toward Serbs and afterwards towards Serbian state has long enduring history. This history got new impetus after the forming of Congregation for the religious propaganda. Vatican led policy against the forming of first Yugoslavia between the World Wars and worked on its destabilization especially after the forming of catholic organization named the Cruisers. During the II WW Vatican took full cooperation with Ustashi’s Independent State of Croatia. During this period Catholic church headed by the Holy Chair approved mass introduction into Catholicism of Serbs and their mass killing that became real genocide in scope. In last crisis during the nineties Vatican gave full help in disintegration of Yugoslavia in order to make easier proselytism on the East.

  17. Economic feasibility of biochemical processes for the upgrading of crudes and the removal of sulfur, nitrogen, and trace metals from crude oil -- Benchmark cost establishment of biochemical processes on the basis of conventional downstream technologies. Final report FY95

    During the past several years, a considerable amount of work has been carried out showing that microbially enhanced oil recovery (MEOR) is promising and the resulting biotechnology may be deliverable. At Brookhaven National Laboratory (BNL), systematic studies have been conducted which dealt with the effects of thermophilic and thermoadapted bacteria on the chemical and physical properties of selected types of crude oils at elevated temperatures and pressures. Current studies indicate that during the biotreatment several chemical and physical properties of crude oils are affected. The oils are (1) emulsified; (2) acidified; (3) there is a qualitative and quantitative change in light and heavy fractions of the crudes; (4) there are chemical changes in fractions containing sulfur compounds; (5) there is an apparent reduction in the concentration of trace metals; and (6) the qualitative and quantitative changes appear to be microbial species dependent; and (7) there is a distinction between biodegraded and biotreated oils. The downstream biotechnological crude oil processing research performed thus far is of laboratory scale and has focused on demonstrating the technical feasibility of downstream processing with different types of biocatalysts under a variety of processing conditions. Quantitative economic analysis is the topic of the present project which investigates the economic feasibility of the various biochemical downstream processes which hold promise in upgrading of heavy crudes, such as those found in California, e.g., Monterey-type, Midway Sunset, Honda crudes, and others.

    Full Text Available This paper aims to present opportunities cultural educational social policy and the Serbian people during the Turkish government. The intention is also to investigate the extent and level of education - literacy through the process of learning, reading, writing and acquiring new knowledge. The paper will also be discussed and the impact of other counters and their schools (Russia, Germany, Greece on the entire educational system in Serbia in the Serbian education period. Legal regulation and development of spiritual awareness and desire for literacy, will also find its place in this paper. Based on all the foregoing, it follows that the literacy during the Ottoman rule was very limited, and that the small number and percentage of population of certain social groups (nobility, clergy. There fore education was meager and insignificant, that and that, as concept, was reduced to literacy. Also, the church was the meeting place of all those who strove for literacy, and together with the monasteries of the first and only school in which they were taught reading and writing. During the First Serbian Uprising, except churches, the need for some kind of education begins to have, and government or authority which forms a first and basic institution of society. Looking at the wider development of literacy in Serbia can be concluded that education had its ups and downs, which are periodically changed depending on the social and political conditionally. Thus, at the close of the Middle Ages to the territorial possession of Despot Stefan Lazarevic (1389-1427 and its owner George Brankovic (1427-1456, with constant theats to the Turkish conquest occurred one interesting moment. Thjere is still an independent country, and despite the double vassalage to Turkey and Hungary, has seen a tumultuous economy and education rise, which was also the basis for the rise of Serbia culture. In the Serbian despots then we come to real cult of art and education, as earlier periods are not known. In conclusion it also poses the fact that Serbian teachers from Austrija were the pioneers of education and literacy in Serbia. They are indebted to Serbian culture, not only in the field of education but also in healthcare, government, literature, art, etc. For Serbia, where in 1804. began its process of national liberation and cultural awakening, surely it can be concluded, among other things, that it s parallel with its general social development proceeded and the development of its education and development of education and enlightenment, which in its role was always a natural support and indispensable factor in the statehood and grow into a formulation.

    Winery wastewater is characterized by high organic content consisting of alcohols, acids and recalcitrant high-molecular-weight compounds (e.g. polyphenols, tannins and lignins). So far, biological treatment constitutes the best available technology for such effluents that are characterized by high seasonal variability; however the strict legislation applied on the reclamation and reuse of wastewaters for irrigation purposes introduces the need for further treatment of the bioresistant fraction of winery effluents. In this context, the use of alternative treatment technologies, aiming to mineralize or transform refractory molecules into others which could be further biodegraded, is a matter of great concern. In this study, a winery effluent that had already been treated in a sequencing batch reactor was subjected to further purification by homogeneous and heterogeneous solar Fenton oxidation processes. The effect of various operating variables such as catalyst and oxidant concentration, initial pH, temperature and lamp power on the abatement of chemical oxygen demand (COD), dissolved organic carbon (DOC), color, total phenolics and ecotoxicity has been assessed in the homogeneous solar Fenton process. In addition, a comparative assessment between homogeneous and heterogeneous solar Fenton processes was performed. In the present study the homogeneous solar Fenton process has been demonstrated to be the most effective process, yielding COD, DOC and total phenolics removal of about 69%, 48% and 71% in 120 min of the photocatalytic treatment, respectively.

  1. In-situ active/passive bioreclamation of vadose zone soils contaminated with gasoline and waste oil using soil vapor extraction/bioventing: Laboratory pilot study to full scale site operation

    The use of soil venting to supply oxygen and remove metabolites from the biodegradation of light hydrocarbons is a cost effective in-situ remediation approach. To date, little data exists on the effective in-situ bioreclamation of vadose zone soil contaminated with waste/hydraulic oil without excavation or the addition of water or nutrients to degrade the heavy petroleum contaminants. Gasoline and waste/hydraulic oil contaminated soils below an active commercial building required an in-situ non-disruptive remediation approach. Initial soil vapor samples collected from the vadose zone revealed CO 2 concentrations in excess of 16% and O 2 concentrations of less than 1% by volume. Soil samples were collected from below the building within the contaminated vadose zone for laboratory chemical and physical analysis as well as to conduct a laboratory biotreatability study. The laboratory biotreatability study was conducted for 30 days to simulate vadose zone bioventing conditions using soil taken from the contaminated vadose zone. Results of the biotreatability study revealed that the waste oil concentrations had been reduced from 960 mg/Kg to non-detectable concentrations within 30 days and the volatile hydrocarbon content had decreased exponentially to less than 0.1% of the original concentration. Post treatability study biological enumeration revealed an increase in the microbial population of two orders of magnitude

  2. Ethnic stereotypes among Bosniak and Serbian youth in Bosnia and Herzegovina

    2004-01-01

    Full Text Available This research, which used a sample of 407 members of both Bosniak and Serb nationality in Sarajevo and Banja Luka, analyzes the structure and content of ethnic stereotypes of Bosnia and Herzegovina's youth. The results reveal significant negative stereotypes of Bosniak and Serb youth toward one another, but also show conspicuous similarities regarding their stereotypes toward other ethnic groups. The concluding remarks set forth theoretical and pragmatic consequences of the results obtained. It can be concluded that people are clearly divided into groups based on the ethnicity criterion. This, substantiated by the earlier history of conflict, creates perceptions and assessments saturated by negative attributes, and can lead to potential conflicts in future. The research suggests that possible solution lies in a conflict resolution education, greater interethnic communication.

    2015-12-01

    Full Text Available This paper analyzes the census in Kosovo in 2011 with specific focus on the political implications and ethnic minority rights. A key conclusion is that this census highly influences public policy-making, and with regard to minority rights, the census data, in comparison to previous estimates and Kosovo Constitutional provisions, is not favorable to ethnic minorities. Expressing a lower number of minorities in total terms, the 2011 census explicitly reduced the representation of minorities at the central and local institutions, and consequently affected budget allocations. However, we must be aware that to some extent, because of the full boycott in the North by local Serbs, and the partial boycott in the South by the Roma and Serb communities, comparisons are limited and the data needs to be analyzed with care.

    Full Text Available In contemporary world globalization, along with many perplexities, increasingly takes on the universal/cosmopolitan character in spite of all geographical, national, racial, religious and alignment barriers. Information exchange, scientific achievements and technology are nowadays world process. Economy increasingly becomes global. Serbia and Serbian people have their own specific character, which is defined by three significant characteristics: sovereignty and territorial integrity, aspirations to social justice, the rule of people and democracy. The creators of global society should take into consideration these three important characteristics of Serbian people with which Serbian political elite is to familiarize them, for the sake of more rapid and complete process of integration of Serbs into global processes from both Serbia and its neighboring countries would benefit.

    Doctor Jovan Andrejević Joles was one of the most educated Serbs of the 19th century, a medical doctor, scientist, journalist and translator. He was born in 1883 in Novi Sad. Even as a student of medicine he was active in scientific work, which resulted in a paper entiteled "The fine structure of the liver," later published in one of the most eminent medical journals in Europe. He completed the study of medicine in Vienna. He did not accept the position at the Medical Faculty in Vienna, and returned to Novi Sad, where he quickly gained an excellent reputation as a physician. He participated in the founding of the Serbian National Theatre in 1861, he was also one of the most active contributors of Matica Srpska, wrote many articles, critics and reviews, and was also regarded as the founder of aesthetic romanticism in Serbs. With Laza Kostić, he was the first among the Serbs to translate Shakespeare. At that time, when he was only 30 years old, he wrote about a brand-new art - photography. He lived in a harmonious marriage with Jelena - Ilka Bajić, who after Joles' death remarried to a captain of the Serbian army, and after his murder, became famous for the assassination attempt of King Milan Obrenović (recorded in history textbooks as the "Rebellion of Ilka"). Dr. Jovan Andrejevć died prematurely of tuberculosis, at that time an incurable disease, in 1864 in Novi Sad.

    Full Text Available Serbian military aggression against Croatia and Bosnia and Herzegovina resulted in the destruction of much material property: factories, schools, churches and other such items. However, the most tragic effects of the war events involved the killing of people, the suffering of civilians and the collapse of social structures. In this regard, in ethnically mixed areas, most threatened were the primary social groups (neighbour and friendship bonds that are a condicio sine qua non for the formation and endurance of local communities. In so much as this occurred, it is possible to explicitly and unequivocally state that the war practically destroyed all the local communities in the occupied and later liberated areas of the Brod-Posavina county. Therefore, the process of return of war migrants and the (reformation of local communities brings us to question of how actors in this process (refugees-immigrants, returnees-Croats, returnees-Serbs experience and imagine the possibility of establishing coexistence, and to what degree and in which way does their own behaviour influence the mentioned process. Do significant differences exist in the responses and behaviour among people of different age, sex and level of education? What are the prospects in regard to neighbourship and friendship in local communities? What are the values that might bring together war migrants in the mentioned area? At any rate, it is well known that without a minimum level of conformism and consensus to draw people together, coexistence is impossible. How is it possible to renew what has broken down, as well as the destroyed individual assets, especially neighbourship and friendship? The basic assumption in this paper stems from the author’s belief that coexistence and cooperation between all groups in the western part of the Brod-Posavina county is possible only if primary social relationships – especially neighbourship and friendship – are renewed.

    The U.S. Department of Defense has considered phytoremediation to be a feasible technology to clean up contaminated sites in remote, cold regions. In cold regions, contaminated soil treatment rates are reduced by low temperatures and short treatment seasons. One technology that overcomes these limitations is rhizosphere-enhanced biotreatment which is a low-cost, simple technology that stimulates indigenous microorganisms. A study was conducted in which rhizosphere-enhanced treatment was compared to natural attenuation at a petroleum-contaminated site in Fairbanks, Alaska. The effects of vegetation and nutrient additions on remediation of soils contaminated with both diesel and crude oil were examined. Soil total petroleum hydrocarbon (TPH) concentrations in both treatments decreased relative to the initial TPH concentrations. After 640 days of treatment, the rhizosphere treatment had significantly lower TPH concentrations. It was concluded that an improved understanding of the time-dependent relationships between contaminant concentration changes and microbial community changes, along with improved techniques to characterize microbial communities, could provide a useful tool for monitoring the functioning of phytoremediation. 25 refs., 8 figs.

    Bioregeneration of nitrate-laden ion exchange brine is desired to minimize its environmental impacts, but faces common challenges, i.e., enriching sufficient salt-tolerant denitrifying bacteria and stabilizing brine salinity and alkalinity for stable brine biotreatment and economically removing undesired organics derived in biotreatment. Incorporation of 0.25 M bicarbonate in 0.5 M chloride brine little affected resin regeneration but created a benign alkaline condition to favor bio-based brine regeneration. The first-quarter sulfate-mainly enriched spent brine (SB) was acidified with carbon source acetic acid for using CaCl2 at an efficiency >80% to remove sulfate. Residual Ca(2+) was limited below 2 mM by re-mixing the first-quarter and remained SB to favor denitrification. Under [Formula: see text] system buffered pH condition (8.3-8.8), nitrate was removed at 0.90 gN/L/d by hematite-enriched well-settled activated sludge (SVI 8.5 ml/g) and the biogenic alkalinity was retained as bicarbonate. The biogenic alkalinity met the need of alkalinity in removing residual Ca(2+) after sulfate removal and in CaCl2-induced CaCO3 flocculation to remove 63% of soluble organic carbon (SOC) in biotreated brine. Carbon-limited denitrification was also operated after activated sludge acclimation with sulfide to cut SOC formation during denitrification. Overall, this bicarbonate-incorporation approach, stabilizing the brine salinity and alkalinity for stable denitrification and economical removal of undesired SOC, suits long-term cost-effective brine bioregeneration.

    During the past several years, a considerable amount of work has been carried out showing that microbially enhanced oil recovery (MEOR) is promising and the resulting biotechnology may be deliverable. At the Brookhaven National Laboratory (BNL), systematic studies have been conducted which dealt with the effects of thermophilic and thermoadapted bacteria on the chemical and physical properties of selected types of crude oils at elevated temperatures and pressures. Particular attention was paid to heavy crude oils from Venezuela, California, Alabama, Arkansas, Wyoming, Alaska, and other oil producing areas. Current studies indicate that during the biotreatment several chemical and physical properties of crude oils are affected. The oils are (1) emulsified; (2) acidified; (3) there is a qualitative and quantitative change in light and heavy fractions of the crudes; (4) there are chemical changes in fractions containing sulfur compounds; (5) there is an apparent reduction in the concentration of trace metals; (6) the qualitative and quantitative changes appear to be microbial species dependent; and (7) there is a distinction between {open_quotes}biodegraded{close_quotes} and {open_quotes}biotreated{close_quotes} oils. Preliminary results indicate the introduced microorganisms may become the dominant species in the bioconversion of oils. These studies also indicate the biochemical interactions between crude oils and microorganisms follow distinct trends, characterized by a group of chemical markers. Core-flooding experiments have shown significant additional crude oil recoveries are achievable with thermophilic microorganisms at elevated temperatures similar to those found in oil reservoirs. In addition, the biochemical treatment of crude oils has technological applications in downstream processing of crude oils such as in upgrading of low grade oils and the production of hydrocarbon based detergents.

    Full Text Available The sample of the research presented in this paper consisted of 575 children age 10 and 11 from four of Novi Sad`s primary school. 58 of them were Roma and the rest were Serbs, Hungarians, Croats, etc. The paper deals with the social distance toward the six ethnic groups (Roma, Serbs, Croats Hungarians, Slovaks and Ruthenians, as well as stereotypes of Roma both in Roma and non-Roma children. Sample has also been divided in two by the criteria of Roma children attending the same classes as the children in the sample or not. The results show that social distance toward the Roma is higher than any other social distance in this sample. Also, we were not able to find any significant differences in this social distance between children who attend the school with the Roma children and those who do not. As could be expected, the auto stereotypes were more positive than the hetero stereotypes.

Cuando Vojvodina formó parte del Reino de los serbios, croatas y eslovenos creados el 1 de diciembre de 1918 el poder de Belgrado se centró en el desarrollo de las zonas del Sur habitadas por serbios. Muchos húngaros y gernamos, la mayoría en Banat, escapó en los últimos meses de la II Guerra Mundial; de igual modo, se asentaron contingentes poblaciones de serbios venidos de Lika, Bosnia, Montenegro y Kosovo. Esto provocó que, con el tiempo, se conformara una mayoría de serbios. Muchos emigrantes se movieron hacía Vojvodina en función de los cambios políticos ocurridos desde los noventa hasta hoy. El número de húngaros ha decrecido convirtiéndose en una minoria que convive con los movimientos poblacionales de los serbios.

    This book attempts to approach the topic of biodegradation of hazardous wastes in a holistic fashion. The issues of science, engineering and regulation are all addressed. As much as possible, both theoretical and practical considerations have been dealt with. Selection of bacteria for the specific purpose of degrading compounds is discussed at the bench-scale to the field level. Engineering theory as applied to growth on toxic substances is discussed. The legal issues are covered. There are also several examples of field studies indicating the current usage of biodegradation, both within reactors and in situ. The use of biodegradation is compared with other mechanisms of disposal, in terms of time limitations, degradation limitations and, perhaps most important, cost. Individual papers have been processed separately for inclusion in the appropriate data bases

    Wheat straw was submitted to a pre-treatment by the basidiomycetous fungi Euc-1 and Irpex lacteus, aiming to improve the accessibility of cellulose towards enzymatic hydrolysis via previous selective bio-delignification. This allowed the increase of substrate saccharification nearly four and three times while applying the basidiomycetes Euc-1 and I. lacteus, respectively. The cellulose/lignin ratio increased from 2.7 in the untreated wheat straw to 5.9 and 4.6 after the bio-treatment by the basidiomycetes Euc-1 and I. lacteus, respectively, thus evidencing the highly selective lignin biodegradation. The enzymatic profile of both fungi upon bio-treatment of wheat straw have been assessed including laccase, manganese-dependent peroxidase, lignin peroxidase, carboxymethylcellulase, xylanase, avicelase and feruloyl esterase activities. The difference in efficiency and selectivity of delignification within the two fungi treatments was interpreted in terms of specific lignolytic enzyme profiles and moderate xylanase and cellulolytic activities.

    The US Army Kwajalein Atoll (USAKA) Base, located in the Republic of the Marshall Islands (RMI) in the east-central Pacific Ocean, has significant petroleum hydrocarbon contamination resulting from years of military activities. Because of its remoteness, the lack of on-site sophisticated remediation or waste disposal facilities, the amenability of petroleum hydrocarbons to biodegradation, and the year-round temperature favorable for microbial activity, USAKA requested, through the Hazardous Waste Remedial Actions Program (HAZWRAP), that a project be conducted to evaluate the feasibility of using bioremediation for environmental restoration of contaminated sites within the atoll. The project was conducted in four distinct phases: (1) initial site characterization and on-site biotreatability studies, (2) selection of the demonstration area and collection of soil columns, (3) laboratory column biotreatability studies, and (4) an on-site bioremediation demonstration. The results of phases (1) and (3) have been detailed in previous reports. This report summarizes the results of phases (1) and (3) and presents phases (2) and (4) in detail

    Full Text Available St. Simeon – the eternal ruler of the Serbs The article discusses the development of the cult of St. Simeon (Stefan Nemanja, ca. 1113–1199 in the thirteenth century as a core of the ruler’s ideology and a mirror of the political changes in Serbia. The main task is to discover when, how and why the founder of the Nemanidi dynasty became the first and eternal ruler of the Serbs, analyzing the choice of the biblical motifs and quotations in the introductions and in a number of other selected places in the main ideological texts of the period: two Hilandar Monastery charters, one written from the Grand Zhupan Stefan Nemanja himself in 1198, the other – written in 1207/8 by his son, Stefan the First-Crowned as well as three Vitae of St. Simeon, written by his sons St. Sava and St. Stefan and by the Hilandar’s hegumenos Domentian. The study applies the approach of biblical thematic clues, proposed by Ricardo Picchio, hitherto unused for these sources, and takes into consideration also some results obtained through the investigation of early Slavic Orthodox texts from the point of view of the same concept. One conclusion which was arrived at is that the same tradition of biblical exegesis con­cerning the concepts of the Unfailing Mercy and Continuity of the Apostleship and the motifs of Conversion/New Nations and the Blessed Generation of the Upright, is consistently used in Serbian text for the same purpose – the affirmation of one’s own saints and, through their cults, confirmation of own “institutions of salvation” (ruling dynasty, church organization, liturgical language as proceeding directly from God. In the three Vitae of St. Simeon different inherited models and patterns are adopted, corresponding to different versions of Ideal Ruler and of legitimization in changing political circumstances in Serbia and in European South-East in the thirteenth century.

    Toxicity of nanoparticles remains to be a major issue in their application to the biomedical field. Aloe vera (AV) is one of the most widely exploited medicinal plants that have a multitude of amazing properties in the field of medicine. Methanol extract of Aloe vera can be used as a novel stabilising agent for quantum dots to reduce toxicity. We report the synthesis, structural characterization, antibacterial activity and cytotoxicity studies of ZnS:Mn quantum dots synthesized by the colloidal precipitation method, using methanol extract of Aloe vera (AVME) as the capping agent. The ZnS:Mn quantum dots capped with AVME exhibit superior performances in biocompatibility and antibacterial activity compared with ZnS:Mn quantum dots without encapsulation.

    Full Text Available Biodegradation of azo dyes is difficult due to their complex structures and low BOD to COD ratios. In the present study, the efficiency of using Fenton’s reagent (H2O2 + Fe2+ as a pretreatment process to enhance microbial transformation of reactive black 5 (RB5 in an aqueous system was evaluated. The RB5 with an initial concentration of 250 mg/L was decolorized up to 90% in 60 h by using a bacterial consortium. Fenton’s reagent at a Fe2+ concentration of 0.5 mM and H2O2 concentration of 2.9 mM (molar ratio, 1:5.8 was most effective for decolorization at pH = 3.0. The extent of RB5 removal by the combined Fenton–biotreatment was about 2 times higher than that of biotreatment alone. The production of some aromatic amines intermediates implied partial mineralization of the RB5 in Fenton treatment alone; in addition, decreasing of GC-MS peaks suggested that dearomatization occurred in Fenton-biological process. Fenton pretreatment seems to be a cost–effective option for the biotreatment of azo dyes, due mainly to the lower doses of chemicals, lower sludge generation, and saving of time. Our results demonstrated positive effects of inoculating bacterial consortium which was capable of dye biodegradation with a Fenton’s pretreatment step as well as the benefits of low time required for the biological process. In addition, the potential of field performance of Fenton-biological process because of using bacterial consortium is an other positive effect of it.

    1991-01-01

    Scientists at the Institute of Gas Technology (IGT) have focused on enhancing destruction of polyaromatic hydrocarbons (PAHs) present as pollutants in manufactured gas plant (MGP) soils. The factor that bears the most restrictive influence on successful biological PAH degradation is low pollutant transfer from soil into an aqueous environment where biotreatment processes can take place. Physical and chemical enhancements were used in conjunction with biological processes. Physical enhancements overcame the mass transfer problem and made possible the biological destruction of aromatic hydrocarbons. One- to three-ring aromatic hydrocarbons were readily biodegraded in liquid, soil slurry, and - to a lesser degree - composted soil systems. Four- to six-ring PAHs remained persistent but were effectively destroyed when chemical co-treatments were used. Combined biological/chemical/physical processes are currently being tested to achieve the most extensive PAH degradation possible for MGP soils

    Full Text Available Within a decade, Kosovo has compromised twice: accepting the process of decentralization in order to achieve independence and international recognition, through the President Martti Ahtisaari’s Comprehensive Proposal for the Kosovo Status Settlement (2 February 2007, and finally, by approving to offer autonomy for Kosovo Serbs for the sovereignty, but still within the limits of the Ahtisaari Plan. Coincidentally, the same Serbian political parties which had fought three wars, resulting in dissolution of the state (Former Yugoslavia at that time (the Socialist Party and the Serbian Radical Party, now are in power in the Republic of Serbia, and have the possibility to finally solve the Kosovo case, and to open the perspective for this part, Europe’s black hole, to be engaged in global integration. Statements by senior Serbian politicians are positively shifting, compared to the radicalization of the relations between Albanians and Serbs three decades ago and it is believed that the developments will evolve towards rational choice and acceptance by the parties. Being under pressure by difficult socio-economic situation and need for integration processes, both sides undertake risky and unpopular steps by signing unclear political and verbal agreements on normalization of relations, which may produce difficult solving externalities in the future. The risk lies in the possibility of further damaging the Kosovo’s “piece of the cake”, after every refusal step by the Serbian side, which will damage the interest of Kosovo side according to the “zero sum” game. Analyses of the dialogue process between Kosovo and Serbia reflect the mixed benefits to the parties, resulting in not very soon European integration, and with hope on difficult but necessary reconciliation between Albanians and Serbs in the region. The broken, after the war established, status quo is better than entering into a protracted conflict in the middle of Europe.

    Full Text Available The essay depicts an attempt to reform ortography taken by a military doctor Đuro Augustinović through which he strived to unify the Southslavic people, especially the Croats and the Serbs. The potential movements that he was exposed to and that he was influenced by were stated in the essay, along with his persevere promotion of his own standpoint. Since his proposal appeared in amidst of Gaj's triumphant orto-graphical proposals, his ideas were not widely accepted. In the spirit of ongoing Panslavic movements Augustinović insisted on reconstruction of Latin script by introducing Cyrillic graphems (in opposition to Gaj's solutions which involved diacritic signs intending to unify in writing the two bigger nations. This equilization of Cyrillic and Latin script failed because both, the Croats and the Serbs had a deep-rooted tradition which prevented every intervention in its core. His untiring advocating of phonetical solutions in ortographical issues had a similar destiny. Therefore, Augustinović's attempt remained solely a testimony of an era without a true impact.

    Full Text Available Kosovo and Metohija, the heartland of medieval Serbia, of her culture politics and economy (1204-1455, experienced continuous waves of spiralling violence, forced migration and colonization under centuries-long Ottoman rule (1455-1912. A region which symbolizes the national and cultural identity of the Serbian nation as a whole now has an Albanian majority population, who consider it an ancient Albanian land, claiming continuity with ancient Illyrians. Kosovo was reincorporated into Serbia (1912 and Yugoslavia (1918 as a region lacking tradition of interethnic and interreligious tolerance and cooperation. The two rivalling Kosovo nations, Albanians and Serbs, remained distant, maintaining limited interethnic communication throughout the twentieth century. The mounting national and ideological conflicts, reinforced by the communist ideology made coexistence almost impossible, even after the 1999 NATO bombing campaign and establishment of KFOR-secured UN administration. Kosovo’s unilateral declaration of independence in February 2008 is a dangerous attempt to establish a second Albanian state extended into the heartland of Serbia, a failed state cleansed of both Serbs and other major non-Albanian communities.

    Membranes are essential to a range of applications, including the production of potable water, energy generation, tissue repair, pharmaceutical production, food packaging, and the separations needed for the manufacture of chemicals, electronics and a range of other products. Therefore, they are considered to be "dominant technologies" by governments and industry in several prominent countries--for example, USA, Japan and China. When combined with catalysts, membranes are at the basis of life, and membrane-based biomimetism is a key tool to obtain better quality products and environmentally friendly developments for our societies. Biology has a main part in this global landscape because it simultaneously provides the "model" (with natural biological membranes) and represents a considerable field of applications for new artificial membranes (biotreatments, bioconversions and artificial organs). In this article, our objective is to open up this enthralling area and to give our views about the future of membranes in biotechnology.

    1992-01-01

    Inadvertent release of fuels and solvents into soil has resulted in groundwater contamination across the United States. This paper reports on the development of biologically based systems for treating mixtures of chemical contaminants which often requires knowledge of both degradative pathways and interactions between individual chemicals. These issues may necessitate the use of specialized microorganisms and/or treatment systems designed to overcome these limitations. One strategy for the treatment of chemical mixtures which cannot be source separated, such as contaminated groundwater, is a modular system to sequentially biodegrade groups of compatible chemicals. A two-stage bioreactor system was constructed for the treatment of groundwater contaminated with benzene and TCE. This treatment system is undergoing development for a field pilot demonstration. Successful implementation of this system should result in significant cost and time savings compared to competitive technologies

    When the interface between two radially unbounded, viscous fluids lying vertically in a stable configuration (denser fluid below) at rest, is perturbed, radially propagating capillary-gravity waves are formed which damp out with time. We study this process analytically using a recently developed linearised theory. For small amplitude initial perturbations, the analytical solution to the initial value problem, represented as a linear superposition of Bessel modes at time t = 0 , is found to agree very well with results obtained from direct numerical simulations of the Navier-Stokes equations, for a range of initial conditions. Our study extends the earlier work by John W. Miles who studied this initial value problem analytically, taking into account, a single viscous fluid only. Implications of this study for the mechanistic understanding of droplet impact into a deep pool, will be discussed. Some preliminary, qualitative comparison with experiments will also be presented.

    An innovative plant to treat oilfield produced wastewater is being constructed in Trinidad and Tobago following recent regulations and industrial water supply challenges. The 4,100m3/day treatment system, developed by Golder Associates, will produce water for industrial reuse and effluent that meets new regulations. The treatment stages include: oil-water separation by gravity, equalization with a two-day capacity basin, dissolved air flotation, cooling, biotreatment/settling with immobilized cell bioreactors (ICB) technology, prefiltration/reverse osmosis and effluent storage/transfer. This advanced system will provide several important benefits including the elimination of inland discharge of minimally-treated water and the reduction of environmental and public health concerns. In addition, it will provide a new source of industrial water, resulting in a decrease in demand for fresh water. The success of this plant could lead to additional facilities in other oil field locations, expanding economic and environmental benefits of water reuse.

    2015-01-01

    Bacillus weihenstephanensis RI12, isolated from hydrocarbon contaminated soil, was assessed for Congo Red bio-treatment potency. Results suggested the potential of this bacterium for use in effective treatment of Congo Red contaminated wastewaters under shaking conditions at acidic and neutral pH value. The strain could tolerate higher doses of dyes as it could decolorize up to 1,000 mg/l of Congo Red. When used as microbial surfactant to enhance Congo Red biodecolorization, Bacillus subtilis SPB1-derived lipopeptide accelerated the decolorization rate and maximized the decolorization efficiency at an optimal concentration of biosurfactant of about 0.075%. Studies ensured that Congo Red removal by this strain could be due to an adsorption phenomena. Germination potencies of tomato seeds using the treated dyes under different conditions showed the efficient biotreatment of the azo dye Congo Red especially with the addition of SPB1 biosurfactant. To conclude, the addition of SPB1 bioemulsifier reduced energy costs by reducing the effective decolorization period; the biosurfactant stimulated bacterial decolorization method may provide a highly efficient, inexpensive and time-saving procedure in the treatment of textile effluents.

    Considering the importance of methylotrophs in industrial wastewater treatment, focus of the present study was on utilization of a methylotrophic bacterial consortium as a microbial seed for biotreatment of a variety of industrial effluents. For this purpose, a mixed bacterial methylotrophic AC (Ankleshwar CETP) consortium comprising of Bordetella petrii AC1, Bacillus licheniformis AC4, Salmonella subterranea AC5, and Pseudomonas stutzeri AC8 was used. The AC consortium showed efficient biotreatment of four industrial effluents procured from fertilizer, chemical and pesticide industries, and common effluent treatment plant by lowering their chemical oxygen demand (COD) of 950-2000 mg/l to below detection limit in 60-96 h in 6-l batch reactor and 9-15 days in 6-l continuous reactor. The operating variables of wastewater treatment, viz. COD, BOD, pH, MLSS, MLVSS, SVI, and F/M ratio of these effluents, were also maintained in the permissible range in both batch and continuous reactors. Therefore, formation of the AC consortium has led to the development of an efficient microbial seed capable of treating a variety of industrial effluents containing pollutants generated from their respective industries.

    The biological removal of ammonia and butanal in contaminated air was investigated by using, respectively, a laboratory-scale filter and a scrubber-filter combination. It was shown that ammonia can be removed with an elimination efficiency of 83% at a volumetric load of 100 m3.m-2.h-1 with 4-16 ppm of ammonia. During the experiment percolates were analysed for nitrate, nitrite, ammonium and pH. It was found that the nitrification in the biofilter could deteriorate due to an inhibition of Nitrobacter species, when the free ammonia concentration was rising in the percolate. It should be easy to control such inhibition through periodic analysis of the liquid phase by using a filter-scrubber combination. Such a combination was studied for butanal removal. Butanal was removed with an elimination efficiency of 80% by a scrubber-filter combination at a volumetric load of 100 m3.m-2.h-1 and a high butanal input concentration. Mixing the filter material with CaCO3 and pH control of the liquid in the scrubber resulted in an increase of the elimination efficiency. These results, combined with previous results on the biofiltration of butanal and butyric acid, allow us to discuss the influence of odour compounds on the removal efficiency of such systems and methods for control. The results were used to construct a full-size system, which is described.

    Abstract The biological removal of ammonia and butanal in contaminated air was investigated by using, respectively, a laboratory-scale filter and a scrubber-filter combination. It was shown that ammonia can be removed with an elimination efficiency of 83% at a volumetric load of 100 m3·m–2·h–1 with 4–16 ppm of ammonia. During the experiment percolates were analysed for nitrate, nitrite, ammonium and pH. It was found that the nitrification in the biofilter could deteriorate due to an inhibitio...

  5. Bioremediation of hydrocarbon-contaminated soils: are treatability and ecotoxicity endpoints related?

    International Nuclear Information System (INIS)

    Visser, S.

    1999-01-01

    To determine if there is a relationship between biotreatability and ecotoxicity endpoints in a wide range of hydrocarbon-contaminated soils, including medium and heavy crude oil-contaminated flare pit wastes and lubrication oil contaminated soil, research was conducted. Each test material was analyzed for pH, water repellency, electrical conductivity, available N and P, total extractable hydrocarbons, oil and grease, and toxicity to seedling emergence, root elongation in barley, lettuce and canola, earthworm survival and luminescent bacteria (Microtox), prior to, and following three months of bioremediation in the laboratory. By monitoring soil respiration, progress of the bioremediation process and determination of a treatment endpoint were assessed. The time required to attain a treatment endpoint under laboratory conditions can range from 30 days to 100 days depending on the concentration of hydrocarbons and degree of weathering. Most flare pits are biotreatable, averaging a loss of 25-30% of hydrocarbons during bioremediation. Once a treatment endpoint is achieved, residual hydrocarbons contents almost always exceeds Alberta Tier I criteria for mineral oil and grease. As a result of bioremediation treatments, hydrophobicity is often reduced from severe to low. Many flare pit materials are still moderately to extremely toxic after reaching a treatment endpoint.

    Full Text Available Eucalyptus globulus wood chips were decayed by the lignin-degrading fungus Ceriporiopsis subvermispora as a pretreatment step before kraft pulping. Weight and component losses of wood after the biotreatment were the following: weight (5%, glucans (1.5%, xylans (4.3%, lignin (5.7% and extractives (57.5%. The residual amount of lignin (expressed by the kappa number in pulps from biotreated wood chips was lower than that of pulps from the undecayed control. Depending on the delignification degree, kraft biopulps presented similar or up to 4% increase in pulp yield and 20% less hexenuronic acids (HexA than control pulps. The extended delignification with O2 decreases approximately 50% of the kappa number of the pulps and increases brightness, but had no effect in HexA reduction. The bleaching steps with chlorine dioxide (D0ED1 sequence decreased the kappa number up to 97%, increased pulp brightness up to 84% ISO and decreased HexA amount up to 91%. The use of C. subvermispora in biopulping of E. globulus generated important benefits during the production of kraft pulps that are reflected in a high pulp yield, low residual lignin content, low HexA amount, high brightness and viscosity of the biopulps as compared with pulps produced from untreated wood chips.

  7. An outline for Serbian political tradition in the work of Slobodan Jovanović

    Full Text Available The paper presents considerations of the research on the Serbian political tradition in the work of Slobodan Jovanović (1869-1958, a famous Serbian lawyer, historian, writer and politician, who had a very important role in the development of the Serbian political thought. His work is extensive and varied, but in essence, it relates to the whole of political life in Serbia in the second half of the nineteenth and the first half of the twentieth century. Almost all the elements that make up the Serbian political tradition can be observed in his work. All these elements are contained in the discussion of political institutions in the 19th century Serbia, the rule of the Obrenović dynasty, political parties and party leaders, political ideas and movements in Serbia and Yugoslavia, extreme political behavior and Serbian national character. Jovanović found the origins of Serbian political tradition in the epic poetry and the Kosovo myth, as well as in the poetry of Njegoš. This was a decisive factor in the formation of general ideas about the Serbs as a freedom-loving, heroic and justice-loving people. At the same time, this is where the origins of the idea of Serbs as a disunited nation can be found. Jovanović paid the greatest attention to issues concerning the content of Serbian political tradition, namely: constitutional system, political institutions, parliamentary life, inter-party struggles, political events, the role of the individual in politics and culture, authoritarianism and political violence. He pointed to the political ideas that were coming from the West and which were accepted with mistrust by the patriarchal Serbian society. He appreciated the role of political parties in the democratization of political life, but he also warned of the dangers that threatened national unity: party favouritism and intolerance. In the analyses of the Serbian national character, Jovanović was of the opinion that the Serbs are predominantly a

    Full Text Available Using original documents from the Russian State Military Historical Archive, many of which are introduced for the first time, the author reveals details of creation and activities of the Serbian Volunteer Corps formed from captured soldiers and officers of the Austro-Hungarian army inOdessain the Summer 1916. The same autumn it received a baptism of fire in Dobruja fighting in the separate corps of the Russian army under the command of General Zayonchkovsky. The research interest in studying the activities of “national” and "international" military units within the Russian army is connected with the question of expediency and effectiveness of using such forces against those for whom they have not so long ago shed blood. The author, contrary to the popular opinion of Serbian historians, shows that the call to join the First Serbian division did not arouse mass enthusiasm among the prisoners of war both Serbs and representatives of other Yugoslav nations because of well-founded fears for their close relatives living in the Dual Monarchy and a fairly comfortable stay in the Russian captivity. At the same time, the author emphasizes that this military unit, commanded by officers of the Serbian regular army, was considered by the political leadership ofSerbiaas the basis of the future armed forces of the new state ofYugoslavia. The article shows that the events of the Russian Revolution of 1917 influenced the future fate of this military formation. Many of its soldiers later found themselves on different sides of the front in the Russian civil war. A special attention is payed to the interethnic conflict erupted in the corps between the Serbs on the one side and the Croats and Slovenes on the other. The author introduces a significant body of primary documents showing the nuances of relations in the corps between representatives of various Yugoslav nations. The article emphasizes that the relationship of the Serbs, Croats and Slovenes within the

    Full Text Available Relations between the Serbs and the Bulgarians at the end of the 13th century has been a part of global international relations in the Balkans and in the Danube region. The Tatars (Mongols as the powerful warring people represent external factor that highly influenced those relations. They also made powerful impact on the Serbian and Bulgarian states of the time. The relations between the Serbs and the Bulgarians had not been at the time determined by their attitude toward the Byzantine Empire which was of the Serbian state, while Bulgaria went through tough period of disintegration of the central power. The internal affaires of those two states influenced their mutual relations. During the war with the Byzantine Empire, king Milutin tried to keep Bulgaria on his side, which is the reason why he became related by the marriage to the Bulgarian imperial family. However, strong involvement of Nogay made this alliance non-useful. After 1299 Serbia lost interest for Bulgaria, and behavior toward the queen Ana made two states enter the 14th century as the enemies. The close relations would be maintained with Vidin. In the frame of those relations Milutin's marriage and release of the Bulgarian princess Ana should be regarded, while Stefan's marriage had been motivated differently and happened around 1305/1306.

    Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

    1991-01-01

    Two case studies demonstrate the controlled use of micro-organisms to degrade organic contaminants under aerobic and anaerobic conditions. The aerobic study illustrates the degradation of hydrocarbons in a soil matrix. Data are presented that show a two-phase degradation of total petroleum hydrocarbons (TPH) from about 1,300 ppm TPH to cleanup levels of 100 ppm or less in two months. Total aerobic microorganism and substate-specific degrader counts were tracked throughout the study. Typical total aerobic counts of 10 6 colony forming units (CFU)/g and hydrocarbon degrader counts of 10 4 CFU/g were observed. Hydrocarbon degraders were enumerated on minimal salts media incubated in the presence of hydrocarbon vapors. The anaerobic study documents the successful use of a supplemental carbon source and fertilizers to stimulate indigenous microbe to degrade ketones. A nutrient mix of s polysaccharide, a nitrate electron acceptor and an inorganic orthophosphate was used to augment 100,000 yd 3 of soil contaminated with ketones at about 1,000 ppm. The key elements of a biotreatment project are discussed (i.e., site characterization, treatability studies, biotreatment design, site construction, system maintenance, final disposal and site closure). Lastly, the benefits of bioremediation vs. other remediation alternatives such as landfill disposal, incineration, and stabilization/fixation are discussed in terms of cost and liability

    Real-time methods to monitor stable isotope ratios of CO2 are needed to identify biogeochemical origins of CO2 emissions from the soil-air interface. An isotope ratio infra-red spectrometer (IRIS) has been developed to measure CO2 mixing ratio with δ(13)C isotopic signature, in addition to mixing ratios of other greenhouse gases (CH4, N2O). The original aspects of the instrument as well as its precision and accuracy for the determination of the isotopic signature δ(13)C of CO2 are discussed. A first application to biodegradation of hydrocarbons is presented, tested on a hydrocarbon contaminated site under aerobic bio-treatment. CO2 flux measurements using closed chamber method is combined with the determination of the isotopic signature δ(13)C of the CO2 emission to propose a non-intrusive method to monitor in situ biodegradation of hydrocarbons. In the contaminated area, high CO2 emissions have been measured with an isotopic signature δ(13)C suggesting that CO2 comes from petroleum hydrocarbon biodegradation. This first field implementation shows that rapid and accurate measurement of isotopic signature of CO2 emissions is particularly useful in assessing the contribution of contaminant degradation to the measured CO2 efflux and is promising as a monitoring tool for aerobic bio-treatment.

    For developing laser process technology by interaction between substance and photon, the present state, system, R and D issues and proposal of such technology were summarized. Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary. The basic explication of an unsolved physicochemical phenomenon related to photon and substance, and development of related application technologies are essential. 328 refs., 147 figs., 13 tabs.

    Petroleum hydrocarbon contamination of soils and groundwater associated with Underground Storage Tanks (UST) and aboveground fuel spills has become the focus of many bioremediation efforts. Two case studies in the application of in situ bioremediation to degrade petroleum hydrocarbons are presented. Site A has a history of fuel-handling practices associated with bulk petroleum storage and railroad yard activities. The majority of the hydrocarbon contamination appeared to be the result of past surface spills. Pre-treatment investigation indicated the presence of both volatile and semi- or non-volatile hydrocarbons in the soil. About 3,000 cubic yards of highly contaminated soils was excavated and is being treated in 2, lined, closed loop treatment cells. Groundwater is treated in situ with addition of nutritional cofactors and oxygen introduced through 3 infiltration galleries that are placed 6 feet deep and are each 100 feet in length. Groundwater is also recovered from 3 extraction wells placed 80 to 100 feet from each other, and subsequently treated in a bioreactor. Site B has a history of leaking underground gasoline storage tanks and spills from aboveground diesel fuel associated with county maintenance shed activities. One hundred cubic yards of soil contaminated with diesel components were excavated and treated aboveground in a lined cell. Gasoline contaminated groundwater and soil is being treated in situ by the addition of nutritional cofactors and oxygen through an infiltration gallery 4 feet below surface. The groundwater is recovered from an extraction gallery 92.5 feet down gradient of the infiltration gallery. Nutritional cofactors are introduced on a daily basis with on-site controls. Hydrocarbon reduction, up to 76%, was observed within 3 months of treatment startup in monitoring wells

    This book contains the proceedings of the symposium entitled [open quotes]Environmental Biotechnology: Moving from the Flask to the Field[close quotes] held in October 17th through 19th, 1990, in Knoxville, Tennessee. Environmental biotechnology involves the use of microorganisms and their processes for the clean-up of environmental contamination, specific examples of which include ground-water treatment, treatment of leachates, and clean-up of contaminated soils, sludges, and sediments. In comparison with other technologies, environmental biotechnology (or bioremediation) has the advantages of affecting mineralization of toxic compounds to innocuous end-products, being energy-effective with processes able to take place at a moderate temperature and pressure, safety, and economy and is, therefore, perceived to hold great potential for environmental clean-up. Bioremediation treatment technologies for contaminated soils and groundwater can take the form of: (1) solid-phase biotreatment; (2) slurry-phase treatment; (3) in situ treatment; and (4) combination biological and physical/chemical treatment. The goal of the symposium was to pressure technical accomplishments at the laboratory and field-scale levels, future technical directions and economic, public and regulatory concerns in environmental biotechnology. The book is divided into five major sections on Current Perceptions, Field-Scale Studies, Technical Issues and Concerns in Implementation, Nontechnical Issues and Concerns in Implementation, International Activities, and ends with a critical review of the symposium.

    Full Text Available Currently the transfer of chemical technology is a process that contributes to the technology policy of a country, an industry or an organization in general chemistry. This process requires the application of clear criteria for the proper development of the complex interrelations in the transfer of chemical technology. A group of criteria that are present, are those related to environmental technology which intrinsically define the technology and its impact to the environment. Therefore, the transfer of chemical technology requires technological-environmental criteria defining, in conjunction with other criteria, an adequate process for the selection, acquisition and incorporation of technology in a holistic perspective, so it provides feasible solutions the chemical industry in pursuit of their goals. Then the criterion becomes a benchmark for assessing an appropriate technology transfer process. We performed a theoretical analysis of the technological and environmental criteria, proposing thirty-six (36 technological-environmental criteria interrelated under a systemic approach in the process of transfer of chemical technology, focused on a methodological cycle first run, based primarily on the research-action method. Future research is expected to make a refinement of the criteria from the formulation and validation of metrics so that necessary adjustments are made to optimize the process of transfer of chemical technology.

    Textile dying processes often pollute wastewater with recalcitrant azo and anthraquinone dyes. Yet, there is little development of effective and affordable degradation systems for textile wastewater applicable in countries where water technologies remain poor. We determined biodegradation of actual textile wastewater in biofilters containing rice husks by spectrophotometry and liquid chromatography mass spectrometry. The indigenous microflora from the rice husks consistently performed >90% decolorization at a hydraulic retention time of 67 h. Analysis of microbial community composition of bacterial 16S rRNA genes and fungal internal transcribed spacer (ITS) gene fragments in the biofilters revealed a bacterial consortium known to carry azoreductase genes, such as Dysgonomonas, and Pseudomonas and the presence of fungal phylotypes such as Gibberella and Fusarium. Our findings emphasize that rice husk biofilters support a microbial community of both bacteria and fungi with key features for biodegradation of actual textile wastewater. These results suggest that microbial processes can substantially contribute to efficient and reliable degradation of actual textile wastewater. Thus, development of biodegradation systems holds promise for application of affordable wastewater treatment in polluted environments. PMID:28114377

    Bjelajac Mile

    2007-01-01

    Full Text Available The Kosovo crisis and the dissolution of the SFR of Yugoslavia provoked the scholarly community to respond in many and varied ways. This paper seeks to show how difficult it was for many to 'navigate' between the 'rocks' of hard fact and pure propaganda, and in what ways that open-ended situation echoes in the present. A more important goal, however, is to put forward the results of my research regarding the reliability of the Yugoslav census data of 1931 which may shed clarifying light on the vastly discrepant demographic figures that are currently in use. The 1931 census data for non-Slav minorities were highly classified and intended only for internal government use in response to the needs of external defense or internal order. Migrations of the ethnic Albanians and other ethnic groups in the Kosovo region during the first half of the twentieth century led to significant shifts in ethnic proportions. It is almost impossible to form a clear fact-based picture of what had happened during the First World War and why the Orthodox Christian Serbian population dropped to 21.1% in 1921, almost twice as low as their number in 1911. On the other hand, it is debatable how many ethnic Albanians or Turks permanently emigrated or went in exile in 1918-21. According to various Yugoslav data sources, some 65,000 settlers and state officials came to Kosovo, while some 24,000 Muslims from all parts of Yugoslavia emigrated to Turkey or Albania. The Second World War brought about another significant population shift. Some 10,000 Serbs were killed in 1941, while almost all Christian Orthodox settler families (about 60,000 people were expelled. The expulsion was followed by an inflow of Albanians from Albania proper. Only two thirds of the expelled were permitted to return after 1945. The provisional Yugoslav census of 1948 registered a significant increase for Albanians and a decrease for Serbs and Montenegrins or, expressed in percentage terms, Serbs dropped

  9. Egoism among Serbs: From the ethnopsychological feature to the modern age syndrome

    Full Text Available In difficult and challenging political, economic and cultural circumstances of the present time, altruism and solidarity among people are being challenged, and troubles caused by the material and existential uncertainty often result in the insistence on one's own particularity only, 'I' imposes itself as the highest principle and the greatest good, without consideration (or harm to another man, to a part of a community, or to the community as a whole. Modern man has accepted and internalised ruthlessness as a method used to realise one's own interests, while extreme individualism and the concept of civil society favour and nourish such characteristics among mankind. This is when the general, national interest becomes fiction; view to the collective destiny becomes blurred due to narrow and selfish ambitions of individuals. In this paper we aim at the reactualisation of the problem of 'commonalty' ('rajetinski' mentality among Serbian people, especially among its mercenary intellectuals, as evidenced by numerous authors, from Slobodan Jovanović, Vladimir Velmar-Janković, Vladimir Dvorniković, to Mile Lompar, Đuro Šušnjić and Dobrica Ćosić. This ethnopsychological characteristics, according to Jovan Cvijić, was shaped under specific socio-political, historical and cultural circumstances and conditions, among helpless Orthodox population that was subjected to terror for centuries. Because of the incessant struggle to maintain bare survival, surrounded by suffering and fears, the servile mentality of submissive and dispirited people has developed, with distinct characteristics of insidiousness, humility, fatalism, moral mimicry, pragmatism, deceit and egoism. Have these characteristics radicalized among younger generations in the meantime, and to what extent?.

    2001-01-01

    Oil and gas are produced in many parts of the world. Persons working in the petroleum industry can learn much by communicating with colleagues in other countries, but the opportunities for engineers and scientists to come together and discuss petroleum environmental control practices, technologies, and regulations with representatives of other countries are limited. This paper describes the very useful International Petroleum Environmental Conference (IPEC) which completed its seventh meeting in November 2000 in Albuquerque, New Mexico, USA. The 7th IPEC attracted 350 participants, including 26 participants from countries other than the United States. The 7th IPEC emphasized international issues and included more than 20 papers by international authors or on international topics. The conference covered all aspects of petroleum environmental issues and featured speakers from many disciplines. The conference included technical sessions on the following topics: Legal and Regulatory Issues in the Oil and Gas Industry; Pollution Prevention, Waste Management, and Waste Minimization; Bioremediation of Petroleum Hydrocarbons; Characterization and Remediation of Brine-Impacted Soils; Biotreatment and Bioremediation; International Issues in the Oil and Gas Industry; Phytoremediation of Petroleum Hydrocarbons; Treatment and Management of Produced Water; Forensic Geochemistry and Site Characterization/Technology Transfer; Environmentall Acceptable Endpoints; Desulfurization of Fuels and Waste Streams; Control of Air Emissions; MTBE/Phytoremediation and Natural Attenuation; and Treatment and Remediation of Petroleum Hydrocarbons. The last day of the conference was devoted to a special symposium on 'Innovative Technologies for Subsurface Characterization and Remediation.' The authors recommend this conference as a forum for industry, government, and academia to freely exchange ideas and information

    Biomineralization processes have been applied in situ to protect and consolidate decayed ornamental stone of the Royal Chapel in Granada (Spain). In few years, this conservation treatment has gained worth attention as environmentally friendly methodology for protection and consolidation of limestone because of the compatibilities shown between the new calcium carbonate cement and the original stone substrate. Moreover, the success of this approach may be related to the diversity of the microbiota inhabiting the stone and activated upon the biotreatment application and throughout the time. González-Muñoz et al. (2008) proposed a nutritional solution that activate among the bacteria inhabiting the stone those with carbonatogenic activity. In this study, a long-term (one, two and three years) monitoring of the microbiota present on the treated and untreated stones was done using a molecular strategy, including total DNA extraction, PCR amplification of 16S rRNA sequences, construction of clone libraries and fingerprinting by DGGE (Denaturing Gradient Gel Electrophoresis) analysis. Sequencing of the 16S rDNA revealed the dominant occurrence of members of Actinobacteria (44.20%), Gamma-proteobacteria (30.24%) and Chloroflexi (25.56%) after one year of the biotreatment. Whereas after two years, members of Cyanobacteria (22.10%) appeared and three years after, the microbiota consisted of only Actinobacteria and Cyanobacteria with approximately the same percentage in comparison with the untreated stones, dominated exclusively by Actinobacteria (100%). Fungal diversity followed the same dynamic as bacterial diversity being Ascomicota the predominant order before treatment. After one year, members of Basidiomycota and Viridiplantae appeared on the stone while two years after, the Viridiplantae dominated with a percentage of 84.77%. Finally, three years after the treatment, fungi population started to stabilize again and Ascomicota predominated next to 16.67% of

    2017-08-01

    Bio-treatment of flotation wastewater has been proven to be both effective and economical, as a treatment method. Despite this, little is known regarding the effects of toxic organic floatation reagents such as Dianilinodithiophosphoric acid (DDA), on the microbial community performance or dynamics, which are critical to the effective performance of the bio-treatment reactor. A submerged membrane bioreactor (sMBR) was constructed to continuously treat simulated wastewater contaminated with DDA, an organic flotation reagent that is now considered a significant pollutant. The performance of the sMBR system was investigated at different DDA loading concentrations, with assessment of the effects of DDA on the microbial communities within the sMBR, in particular the biodiversity and succession within the microbial community. Results showed that, with increased DDA loadings, the performance of the sMBR was initially negatively affected, but the system adapted efficiently and consistently reached a COD removal rate of up to 80%. Increased DDA loading concentrations had an adverse effect on the activity of both the activated sludge and microbial communities, resulting in a large alteration in microbial dynamics, especially during the start-up stage and the high DDA loading stage. Strains capable of adapting to the presence of DDA, capable of degrading DDA or utilizing its byproducts, were enriched within the sMBR community, such as Zoogloea, Clostridium, Sideroxydans lithotrophicus, Thiobacillus, Thauera amino aromatica and Alicycliphilus denitrificans.

    TTA8 - Gas technologies points out the various routes Norway can follow to capitalise on the vast resources of natural gas that will be produced in the years to come by developing a strong technology and competence platform. A broad view is taken for the value creation having as basis the continued gas export from NCS to Europe, but also a strong focus on development of gas resources in other parts of the world. The latter can also be seen as part of international positioning for upstream resources and does also include involvements in projects, and export of technology and products. The TTA has structured the analysis into 3 main areas: Gas transport and processing (pipeline, LNG, other); Gas conversion to fuels, chemicals and materials; CO{sub 2} management. In this report, for each of these areas, scenarios based on a gap analysis are presented. One of the key goals has been to identify pacing and emerging technologies for the next 20 years. Based on this, technologies have been mapped according to importance for future competitiveness and technology ambitions. This also includes primary funding responsibilities (public and/or industry). The road map below reflects the key issues in the proposed strategy. The base level of the figure explains areas that will have to be pursued to maintain Norway's role as a key gas and gas technology provider. The second layer represents near term options and possibilities with a reasonable risk profile that could further enhance the Norwegian position given the resources and drive to further develop this industry. As the top layer we have selected some of our 'dreams', what we may achieve if a progressive approach is followed with a strongly innovation based policy. It is acknowledged by the TTA that Norway cannot be a leading technology player in all aspects of the gas value chain. For some technologies we should be an active player and developer, whilst for other technologies we should become a competent buyer and user. This

    This study compares the removal of a mixture of benzene, toluene, ethylbenzene, and all three xylene isomers (BTEX) in mesophilic and thermophilic (50 degrees C) bioreactors. In the mesophilic reactor fungi became dominant after long-term operation, while bacteria dominated in the thermophilic unit. Microbial acclimation was achieved by exposing the biofilters to initial BTEX loads of 2-15 g m(-3) h(-1), at an empty bed residence time of 96 s. After adaptation, the elimination capacities ranged from 3 to 188 g m(-3) h(-1), depending on the inlet load, for the mesophilic biofilter with removal efficiencies reaching 96%. On the other hand, in the thermophilic reactor the average removal efficiency was 83% with a maximum elimination capacity of 218 g m(-3) h(-1). There was a clear positive relationship between temperature gradients as well as CO(2) production and elimination capacities across the biofilters. The gas phase was sampled at different depths along the reactors observing that the percentage pollutant removal in each section was strongly dependant on the load applied. The fate of individual alkylbenzene compounds was checked, showing the unusually high biodegradation rate of benzene at high loads under thermophilic conditions (100%) compared to its very low removal in the mesophilic reactor at such load (<10%). Such difference was less pronounced for the other pollutants. After 210 days of operation, the dry biomass content for the mesophilic and thermophilic reactors were 0.300 and 0.114 g g(-1) (support), respectively, reaching higher removals under thermophilic conditions with a lower biomass accumulation, that is, lower pressure drop.

    Produced water is wastewater that is brought to the surface from natural gas wells during natural gas production. Its constituents, mostly salt, with traces of hydrocarbons and heavy metals, are a significant disposal problem. Argonne National Laboratory (ANL), in partnership with the Gas Research Institute (GRI), has developed a low-cost, low-tech method, in which green plants are used to reduce the volume of produced water. The authors have designed an engineered bioreactor system, which is modeled after natural saline wetland ecosystems. The plant bioreactor system maximizes plant evapotranspiration to reduce wastewater volume and, concurrently, may function as a biological filter to enhance contaminant degradation and immobilization in the root/rhizosphere zone. Halophyte plant species having high salt tolerance and high transpiration rates were selected after they tested them in greenhouse experiments. Models obtained by using their greenhouse findings reduced the volume of the wastewater (up to 6% salt) by 75% in about 8 days. A field demonstration of the bioreactor, designed on the basis of the results from the greenhouse study, is successfully under way at a natural gas well site in Oklahoma. The process could offer the petroleum industry a low-cost biological alternative to existing expensive options.

    The concept of living technology-that is, technology that is based on the powerful core features of life-is explained and illustrated with examples from artificial life software, reconfigurable and evolvable hardware, autonomously self-reproducing robots, chemical protocells, and hybrid electronic-chemical systems. We define primary (secondary) living technology according as key material components and core systems are not (are) derived from living organisms. Primary living technology is currently emerging, distinctive, and potentially powerful, motivating this review. We trace living technology's connections with artificial life (soft, hard, and wet), synthetic biology (top-down and bottom-up), and the convergence of nano-, bio-, information, and cognitive (NBIC) technologies. We end with a brief look at the social and ethical questions generated by the prospect of living technology.

    The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

    Full Text Available Terrorism is a notoriously difficult concept that defies single universal definition. Terrorists intentionally employ violence in order to instill fear in their victims and the wider public. Terrorist movements aim to achieve their political, social and/or religious goals through use of violent acts. (Hoffman, 1998: 43 In most cases terrorism is perpetrated by non-state actors and is "bottom up" challenge to the existing political order. However this article argues that the nature of the crime and not the perpetrator should determine whether some criminal act constitutes terrorism and acts of terror can also be committed by states and/or state actors. In this article, the author will examine the overall strategy and tactics used by the Milosevic and Karadzic regimes in BiH and Kosovo to fulfil their wartime ambitions of maintaining and consolidating control over Serb and Serb-occupied territory, relying primarily upon the indictments and judgments of the ICTY in which they and members of their armed forces acting under their authority have been charged and/or convicted of war crimes and terror, along with reports from international organizations such as the United Nations and other sources. Through an analysis of these tactics against leading definitions of terrorism, it will be demonstrated that rather than fighting against terrorists and insurgents, the Milosevic and Karadzic regimes carried out acts of terror during the wars in Kosovo and BiH, respectively, and furthermore Milosevic was sponsoring state-terrorism in BiH (Blakely, 2012: 3-4.

    Full Text Available The paper presents the study of Ethnical distance with the citizens of Bosnia and Herzegovina. The study was made using Bogardus' scale of social distance, on 1000 interviewees of the Federation of BiH and 850 interviewees of Republika Srpska. The citizens of the Federation of Bosnia and Herzegovina reject the Romas the most, followed by the Albanians and Macedonians. This is followed by the Serbs and Montenegrians, while Slovenians and Croats are the least rejected. Prejudices of the citizens of Bosnia and Herzegovina to the Romas, Albanians, and Macedonians are much more important for the rejection or accepting of offered relations, than it was the case with open hostility and war conflicts with the Serbs, Montenegrians, and Croats. In the Federation of Bosnia and Herzegovina a distinction is made in the degree of ethnical distance of Bosniaks and Croats to the nations who lived in the former Socialist Federal Republic of Yugoslavia. Offered relations are more rejected by the Croats than by the Bosniaks. The citizens of Republika Srpska accept the Muslims (Bosniaks and Romas the least. This is followed by the Croats, Slovenians, and Macedonians, and the Montenegrians are rejected the least. The citizens of Republika Srpska refuse that they or the members of their family marry a member of another nation. Thus they object any possibility for the members of other nations to be found on managing position, or any situation where they themselves would be in a subordinate position in society in relation to the members of other nationalities.

  10. The bay of Cattaro (Kotor school of icon-painting 1680-1860

    Stošić Ljiljana

    2014-01-01

    Full Text Available Relying on post-Byzantine tradition, eleven painters from five generations of the Dimitrijević-Rafailović family, accompanied by Maksim Tujković, painted several thousand icons and several hundred iconostases between the late seventeenth and the second half of the nineteenth century. They worked in major Orthodox Christian monasteries in Montenegro, Kosovo and Metohija, Bosnia and Herzegovina and Dalmatia, but their works can mostly be found in modest village churches in the Bay of Kotor (Cattaro and on the South Adriatic coast. The decoration of these churches was financially supported by the local population headed by elders. Along with a reconstruction of their biographies and a chronological overview of their major works, this paper seeks to trace stylistic changes in the Bay of Kotor school of icon-painting. While simply varying a thematic repertory established in earlier periods, the painters from the Bay of Kotor were gradually introducing new details and themes adopted from Western European Baroque art under indirect influences coming from the monastery of Hilandar, Corfu, Venice and Russia. This process makes this indigenous school of icon-painting, which spanned almost two centuries, comparable to the work of Serbian traditional religious painters (zografs and illuminators active north of the Sava and Danube rivers after the Great Migration of the Serbs (1690. Despite differences between the two, which resulted from different cultural and historical circumstances in which Serbs lived under Ottoman, Venetian and Habsburg rules, similarities in iconography and style, which were inspired by an urge to counteract proselytic pressures, are considerably more important.

    1994-09-01

    The U.S. Department of Energy (DOE) Office of Industrial Technology`s (OIT`s) Technology Benefits Recording System (TBRS) was developed by Pacific Northwest Laboratory (PNL). The TBRS is used to organize and maintain records of the benefits accrued from the use of technologies developed with the assistance of OIT. OIT has had a sustained emphasis on technology deployment. While individual program managers have specific technology deployment goals for each of their ongoing programs, the Office has also established a separate Technology Deployment Division whose mission is to assist program managers and research and development partners commercialize technologies. As part of this effort, the Technology Deployment Division developed an energy-tracking task which has been performed by PNL since 1977. The goal of the energy-tracking task is to accurately assess the energy savings impact of OIT-developed technologies. In previous years, information on OIT-sponsored technologies existed in a variety of forms--first as a hardcopy, then electronically in several spreadsheet formats that existed in multiple software programs. The TBRS was created in 1993 for OIT and was based on information collected in all previous years from numerous industrial contacts, vendors, and plants that have installed OIT-sponsored technologies. The TBRS contains information on technologies commercialized between 1977 and the present, as well as information on emerging technologies in the late development/early commercialization stage of the technology life cycle. For each technology, details on the number of units sold and the energy saved are available on a year-by-year basis. Information regarding environmental benefits, productivity and competitiveness benefits, or impact that the technology may have had on employment is also available.

    This paper presents SERB-CITON solution to isolate the I and C cabinets against shocks, vibrations and seismic movements. The seismic qualification is required because the I and C components installed inside the cabinets are generally sensitive to shocks, vibrations and seismic movements and many times, the manufacturer does not guarantee them for a level of shocks, vibrations and seismic movements higher and equal to the level corresponding to the location where they are installed. The document also presents the solution to isolate such I and C cabinets associated to the hydrogen sulfide compressors located in ROMAG-PROD Drobeta Turnu-Severin. (authors)

  20. Emerging environmental technologies and environmental technology policy

    Science.gov (United States)

    Clarke, Leon Edward

    This dissertation explores the role and design of environmental technology policy when environmental innovation is embodied in emerging environmental technologies such as photovoltaic cells or fuel cells. The dissertation consists of three individual studies, all of which use a simplified, general model industry between an emerging environmental technology and an entrenched, more-polluting technology. It clarifies the situations in which environmental technology policy can achieve high welfare and those in which it cannot; and it separates the possible situations an emerging environmental technology might face into four scenarios, each with its own technology policy recommendations. The second study attempts to clarify which of two factors is having a larger limiting effect on private investment in photovoltaics: the failure to internalize the environmental costs of fossil fuel electricity generation or a broad set of innovation market failures that apply to innovation irrespective of environmental concerns. The study indicates that innovation market failures are probably having a significantly larger impact than incomplete internalization. The third study explores the effectiveness of adoption subsidies at encouraging private-sector innovation. The conclusion is that adoption subsidies probably have only a limited effect on long-term, private-sector research. Two important general conclusions of the dissertation are (1) that optimal technology policy should begin with technology-push measures and end with demand-pull measures; and (2) that the technological response to internalization instruments, such as emissions taxes, may be highly nonlinear.

    2007-01-01

    Full Text Available This work is based on folklore material, which was gathered during ethno linguistic field research of Serbian traditional lexicon and spiritual culture in Medina village in Hungary in 2002. Folklore material is composed of the sayings by the informer Sava Sokic and primarily can be defined as a series of comical narrations. If we look upon these narrations as a genre of oral speech and within context of ethno linguistic interview, we can notice a complex structure of this oral genre. That is, this genre functions as a memorat with typical beginnings and met textual comments. On the other hand, it respects almost all genre norms, which are characteristic for folklore anecdote. Therefore, comic narrations of Save Sokic, and that are valid also for folklore anecdote in general, can be classified as borderline genre - between memorata and fabulata.

    The soil at an oilfield battery site, located 18 kilometres (km) northwest of Devon, Alberta has been contaminated with crude oil and salt, following years of operation. Surrounding the site is flat farmland intended for future agricultural production. A remedial program aimed at complying with Tier I criteria of the Alberta Soil and Water Quality Guidelines for Hydrocarbons at Upstream Oil and Gas Facilities (ASWQG) of Alberta Environment, was developed and implemented. Characterization of the site was carried out in 1997 to delineate a salt plume, followed by a second sampling campaign in 1999, which all together revealed three impacted areas. A supplementary characterization was performed in 2001 by Biogenie in an effort to better determine the nature and level of petroleum contamination and more accurately evaluate the volume of contaminated soil. A three-dimensional Visualization software integrating a Kriging geostatistical model was used for this purpose. The results indicated that an estimated 8,800 cubic metres of contaminated soil would need to be excavated and treated. The next phase involved an evaluation of the various remedial options, which was accomplished using a biotreatability study. The remediation program selected involved the excavation of the contaminated soil and segregation of source material, the ex-situ Biopile treatment of the source material to meet Class II landfill criteria, and the ex-situ Biopile treatment of the contaminated soil followed by its use as backfill on site. The biotreatability study proved to be a strategic tool in the remediation effort. 1 tab., 2 figs.

    Centrifugal mother liquid (CML) is one of the main sources of wastewater produced during the production of polyvinyl chloride in chlor-alkali industry. CML is a typical poorly biodegradable organic wastewater, containing many kinds of refractory pollutants. Specifically, it contains dissolved refractory polymers, especially polyvinyl alcohol (PVA), which can pass though the biotreatment processes and clog the membranes used for further treatment. In this study, to ensure the CML applicable to biotreatment and membrane treatment, a novel efficient and mild technique, air-Fenton treatment, was employed as a pretreatment technique to improve biodegradability of the CML and to break down the polymers in the CML. Firstly, the technique was optimized for the CML treatment by optimizing the main parameters, including the dosage of ferrous sulfate, initial pH of the wastewater, [H2O2]/[Fe(2+)], aeration rate, reaction time, and temperature, based on removal efficiency of COD and PVA from the CML. Then, the optimized technique was tested and evaluated. The results indicated that under the optimized conditions, the air-Fenton treatment could remove 66, 98, and 55 % of the COD, PVA, and TOC, respectively, from the CML. After the treatment, biodegradability of the wastewater increased significantly (BOD/COD increased from 0.31 to 0.68), and almost all of the PVA polymers were removed or broken down. Meanwhile, concentration of the remaining iron ions, which were added during the treatment, was also quite low (only 2.9 mg/L). Furthermore, most of the suspended materials and ammonia nitrogen, and some of the phosphorus in the wastewater were removed simultaneously.

  5. The Serbian state in the work of Byzantine historian Doucas

    2007-01-01

    Full Text Available While the first two chapters of Doucas's historical work present a meagre outline of world history - a sketch which becomes a little more detailed from 1261 on, when the narration reaches the history of the Turks and their conquests in Asia Minor - the third chapter deals with the well-known battle of Kosovo, which took place in 1389. From that point on, the Byzantine historian gives much important information on Serbia, as well as on the Ottoman advances in the Balkans, and thus embarks upon his central theme - the rise of the Turks and the decline of Byzantium. Doucas considers the battle of Kosovo a key event in the subjugation of the Balkan peoples by the Turks, and he shows that after the battle of Kosovo the Serbs were the first to suffer that fate. At the beginning, Doucas says that after the death of Orhan, the ruler (o archgos of the Turks, his son and successor Murad conquered the Thracian towns, Adrianople and the whole Thessaly, so that he mastered almost all the lands of the Byzantines, and finally reached the Triballi (Triballous. He devastated many of their towns and villages sending the enslaved population beyond Chersonesus, until Lazar, son of King Stefan of Serbia (Serbias, who ruled (kraleyōn in Serbia at that time decided to oppose him with all the might he could muster. The Serbs were often called Triballi by Byzantine authors. For the fourteenth century writers Pachymeres, Gregoras, Metochites and Kantakouzenos the Serbs were Triballi. However, Pachymeres and Gregoras refer to the rulers of the Triballi as the rulers of Serbia. Fifteenth century writers, primarily Chalcondyles and Critobulos, use only that name. It seems, nevertheless, that Doucas makes a distinction between the Triballi and the Serbs. As it is known, the conquest of the Serbian lands by the Turks began after the battle on the river Marica in 1371. By 1387. the Turks had mastered Serres(1388 Bitola and Štip (1385, Sofia (1385, Niš (1386 and several

    This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

    Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

    For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

    In the past two years, public and private efforts to promote development and deployment of innovative environmental technologies have shifted from the analysis of barriers to the implementation of a variety of initiatives aimed at surmounting those barriers. Particular attention has been directed at (1) streamlining fragmented technology acceptance processes within and among the states, and (2) alleviating disincentives, created by inadequate or unverified technology cost and performance data, for users and regulators to choose innovative technologies. Market fragmentation currently imposes significant cost burdens on technology developers and inhibits the investment of private capital in environmental technology companies. Among the responses to these problems are state and federal technology certification/validation programs, efforts to standardize cost/performance data reporting, and initiatives aimed at promoting interstate cooperation in technology testing and evaluation. This paper reviews the current status of these initiatives, identifies critical challenges to their success, and recommends strategies for addressing those challenges

    In considering social, economic and ecological impacts of new technologies it is essential to start from an understanding of human nature. This paper explores this issue drawing out some implications for ecological and neoclassical economics. The paper presents two key arguments. First, we argue that there is a growing tension between our evolved human nature and social structures and our emerging technological prowess. Modern technologies give us increasing power to manipulate the very axes of nature: space, time, energy, matter, and life. Technologies are now so powerful they give us abilities our ancestors would consider godlike. The question is posed: Are humans ready to wield the power of the gods? We have the knowledge, but do we have the wisdom? The myth of Prometheus and Pandora is considered as a metaphor for the interaction between technology, nature and universal aspects of human nature developed over eons of evolution. Second, we argue that even a 'technologically optimistic' scenario (employed by some economists) may not actually deliver Utopian outcomes. With technological advancement and diffusion there is a 'technological trickle down effect' whereby potent technologies, once available only to governments and powerful elites, become available to greater numbers of groups and individuals. The more accessible a technology, the more likely its social and ecological impacts will be shaped by the full range and extremes of human nature. These issues have implications for the development and regulation of Promethean technologies such as nuclear energy, genetic engineering and nanotechnology; technologies with unprecedented power and reach through nature. Development and diffusion of such technologies may also have implications for the ethics of the social structure of society. (author)

    1981-06-01

    The relationship between economics and technology, as well as their interaction in production, productivity, project management, and in technology transfer processes are reviewed. Over the last two decades there has been an increasing interest by economists in the technologist's view of technical change and its mechanisms. The author looks at the zone between technology and economics, the technological economics, and discusses the theory of innovation recently sketched out by Nelson and Winter. The relevance to project management and technology transfer of contemporary writing by economists leads to the view that there are welcome signs of a convergence of the conceptual models now emerging and the practical problems of technology management and movement. Economists now seem more willing to come to terms with technology than technologists with economics. The economic significance of the multitudes of technically unglamorous activities in development work is seriously neglected as a result of over-emphasis on the spectacular technological break. If economic elegance were to be admitted to the criteria of success, one might get a significant improvement in the engineering of technological change. 29 references, 4 figure.

    2015-10-01

    Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

    Full Text Available The objective of this study is to analyze the educational practices of using Blackboard in blended learning environments with students of higher education to understand the relationship between technological appropriation and standards of educational technology. To achieve that goal, the following research question was raised: ¿To what extent are the standards of education technology with the appropriation of technology in blended learning environments in higher educa­tion related? The contextual framework of this work includes the following topics: the institution, teaching, teachers and students. The design methodology that was used is of a correlation type. Correlations were carried out to determine the frequency and level in the technological standards as well as the appropriation of technology. In the comparison of the results obtained by the students, the teachers and the platform; we found that students in the school study showed a high degree of technology ownership and this was the same for the performance shown on the technological standards. It was established that teachers play a key role in developing the techno­logical appropriation of students and performance in technology standards.

    Classes of socio-technical hazards allow a characterization of the risk in technology innovation and clarify the mechanisms underpinning emergent technological risk. Emerging Technological Risk provides an interdisciplinary account of risk in socio-technical systems including hazards which highlight: ·         How technological risk crosses organizational boundaries, ·         How technological trajectories and evolution develop from resolving tensions emerging between social aspects of organisations and technologies and ·         How social behaviour shapes, and is shaped by, technology. Addressing an audience from a range of academic and professional backgrounds, Emerging Technological Risk is a key source for those who wish to benefit from a detail and methodical exposure to multiple perspectives on technological risk. By providing a synthesis of recent work on risk that captures the complex mechanisms that characterize the emergence of risk in technology innovation, Emerging Tec...

    Assefa, G.; Eriksson, O.; Frostell, B.

    2005-01-01

    A technology assessment of thermal treatment technologies for wastes was performed in the form of scenarios of chains of technologies. The Swedish assessment tool, ORWARE, was used for the assessment. The scenarios of chains of thermal technologies assessed were gasification with catalytic combustion, gasification with flame combustion, incineration and landfilling. The landfilling scenario was used as a reference for comparison. The technologies were assessed from ecological and economic points of view. The results are presented in terms of global warming potential, acidification potential, eutrophication potential, consumption of primary energy carriers and welfare costs. From the simulations, gasification followed by catalytic combustion with energy recovery in a combined cycle appeared to be the most competitive technology from an ecological point of view. On the other hand, this alternative was more expensive than incineration. A sensitivity analysis was done regarding electricity prices to show which technology wins at what value of the unit price of electricity (SEK/kW h). Within this study, it was possible to make a comparison both between a combined cycle and a Rankine cycle (a system pair) and at the same time between flame combustion and catalytic combustion (a technology pair). To use gasification just as a treatment technology is not more appealing than incineration, but the possibility of combining gasification with a combined cycle is attractive in terms of electricity production. This research was done in connection with an empirical R and D work on both gasification of waste and catalytic combustion of the gasified waste at the Division of Chemical Technology, Royal Institute of Technology (KTH), Sweden

  5. Technology Games: Using Wittgenstein for Understanding and Evaluating Technology.

    Science.gov (United States)

    Coeckelbergh, Mark

    2017-08-15

    In the philosophy of technology after the empirical turn, little attention has been paid to language and its relation to technology. In this programmatic and explorative paper, it is proposed to use the later Wittgenstein, not only to pay more attention to language use in philosophy of technology, but also to rethink technology itself-at least technology in its aspect of tool, technology-in-use. This is done by outlining a working account of Wittgenstein's view of language (as articulated mainly in the Investigations) and by then applying that account to technology-turning around Wittgenstein's metaphor of the toolbox. Using Wittgenstein's concepts of language games and form of life and coining the term 'technology games', the paper proposes and argues for a use-oriented, holistic, transcendental, social, and historical approach to technology which is empirically but also normatively sensitive, and which takes into account implicit knowledge and know-how. It gives examples of interaction with social robots to support the relevance of this project for understanding and evaluating today's technologies, makes comparisons with authors in philosophy of technology such as Winner and Ihde, and sketches the contours of a phenomenology and hermeneutics of technology use that may help us to understand but also to gain a more critical relation to specific uses of concrete technologies in everyday contexts. Ultimately, given the holism argued for, it also promises a more critical relation to the games and forms of life technologies are embedded in-to the ways we do things.

    A Gaussian wave function is used for detailed study of the mass spectra of the B and BS mesons using a Cornell potential incorporated with a 𝒪(1/m) correction in the potential energy term and expansion of the kinetic energy term up to 𝒪(p10) for relativistic correction of the Hamiltonian. The predicted excited states for the B and Bs mesons are in very good agreement with results obtained by experiment. We assign B2(5747) and Bs2(5840) as the 13P2 state, B1(5721) and Bs1(5830) as the 1P1 state, B0(5732) as the 13P0 state, Bs1(5850) as the state and B(5970) as the 23S1 state. We investigate the Regge trajectories in the (J,M2) and (nr,M2) planes with their corresponding parameters. The branching ratios for leptonic and radiative-leptonic decays are estimated for the B and BS mesons. Our results are in good agreement with experimental observations as well as outcomes of other theoretical models. A. K.

    Management of innovation is an important issue for firms and being good at this may be the deciding difference between death and survival. This paper ar-gues, based on 12 case studies, that new technology influence the innovative ca-pability of firms and disturbingly the process appears...... not to be managed in the sense that aims, instruments and resources are unclear. It is observed that new technology is adopted with a limited scope and fo-cus – often to solve a particular technical problem e.g. the quality of specifica-tion are too low. For a single reason a new technology is introduced within...... the firm, which over time becomes a source of innovation. However, through adoption of this new technology firms engage in a mu-tual learning and forming process where the firm learn by using the new technol-ogy. When learning, the firm and the new technology is mutually formed as the firm tries to adopt...

    To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life? This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life. More specifically, we investigate the influence of this factor relative to demographic characteristics, personality traits, and functional limitations in a longitudinal sample of community-dwelling older adults. We report results from a paper-and-pencil survey with 136 older adults between 59 and 92 years of age (mean = 71.4, SD = 7.4). Of those participants, 77 participated in a 2-year follow-up. We assessed self-reports of technology use, subjective technology adaptivity, functional limitations, and the personality traits openness to new experiences and neuroticism. Higher levels of subjective technology adaptivity were associated with technology use at the first measurement as well as increased use over the course of 2 years. Subjective technology adaptivity is a significant predictor of technology use in old age. Our findings contribute to improving the understanding of interindividual differences when using technological innovation in late life. Moreover, our findings have implications in the context of user involvement and may contribute to the successful development of innovative technology for older adults. © 2017 S. Karger AG, Basel.

    Heavy metals can be removed from the sludge using bioleaching technologies at thermophilic condition, thereby providing an option for biotreatment of wasted sludge generated from wastewater treatment. The purposes of this study were to establish a molecular biology technique, real-time PCR, for the detection and enumeration of the sulfur-oxidizing bacteria during the thermophilic sludge bioleaching. The 16S rRNA gene for real-time PCR quantification targeted the bioleaching bacteria: Sulfobacillus thermosulfidooxidans, Sulfobacillus acidophilus, and Acidithiobacillus caldus. The specificity and stringency for thermophilic sulfur-oxidizing bacteria were tested before the experiments of monitoring the bacterial community, bacterial number during the thermophilic sludge bioleaching and the future application on testing various environmental samples. The results showed that S. acidophilus was identified as the dominant sulfur-oxidizing bacteria, while A. caldus and S. thermosulfidooxidans occurred in relatively low numbers. The total number of the sulfur-oxidizing bacteria increased during the thermophilic bioleaching process. Meanwhile, the decrease of pH, production of sulfate, degradation of SS/VSS, and solubilization of heavy metal were found to correlate well with the population of thermophilic sulfur-oxidizing bacteria during the bioleaching process. The real-time PCR used in this study is a suitable method to monitor numbers of thermophilic sulfur-oxidizing bacteria during the bioleaching process.

  15. Use of the Geographic Information System and Analytic Hierarchy Process for Municipal Solid Waste Landfill Site Selection: A Case Study of Najafabad, Iran

    2014-03-01

    Full Text Available Following technological advancements and integrated municipal solid waste management in recent decades, various methods such as recycling, biotreatment, thermal treatment, and sanitary landfills have been developed and employed. Creating sanitary landfills is a major strategy in the integrated solid waste management hierarchy. It is cheaper and thus more common than other disposal methods. Selecting a suitable solid waste landfill site can prevent adverse ecological and socioeconomic effects. Landfill site selection requires the analysis of spatial data, regulations, and accepted criteria. The present study aimed to use the geographic information system and the analytic hierarchy process to identify an appropriate landfill site for municipal solid wastes in Najafabad (Isfahan, Iran. Environmental and socioeconomic criteria were evaluated through different information layers in the Boolean and fuzzy logics. The analytical hierarchy process was applied for weighing the fuzzy information layers. Subsequently, two suitable sites were identified by superimposing the maps from the Boolean and fuzzy logics and considering the minimum required landfill area for 20 years. However, proximity of these two sites to Tiran (a nearby city made them undesirable landfill sites for Najafabad. Therefore, due to the existing restrictions in Najafabad, the possibility of creating landfill sites in common with adjacent cities should be further investigated.

    Studies on Y-chromosomal markers revealed significant genetic differentiation between Southern and Northern (Western and Eastern) Slavic populations. The northern Serbian region of Vojvodina is inhabited by Southern Slavic Serbian majority and, inter alia, Western Slavic (Slovak) and Eastern Slavic (Ruthenian) minorities. In the study, 15 autosomal STR markers were analysed in unrelated Slovaks, Ruthenians and Serbs from northern Serbia and western Slovakia. Additionally, Slovak males from Serbia were genotyped for 17 Y-chromosomal STR loci. The results were compared to data available for other Slavic populations. Genetic distances for autosomal markers revealed homogeneity between Serbs from northern Serbia and Slovaks from western Slovakia and distinctiveness of Serbian Slovaks and Ruthenians. Y-STR variation showed a clear genetic departure of the Slovaks and Ruthenians inhabiting Vojvodina from their Serbian neighbours and genetic similarity to the Northern Slavic populations of Slovakia and Ukraine. Admixture estimates revealed negligible Serbian paternal ancestry in both Northern Slavic minorities of Vojvodina, providing evidence for their genetic isolation from the Serbian majority population. No reduction of genetic diversity at autosomal and Y-chromosomal markers was found, excluding genetic drift as a reason for differences observed at autosomal STRs. Analysis of molecular variance detected significant population stratification of autosomal and Y-chromosomal microsatellites in the three Slavic populations of northern Serbia, indicating necessity for separate databases used for estimations of frequencies of autosomal and Y-chromosomal STR profiles in forensic casework. Our results demonstrate that regarding Y-STR haplotypes, Serbian Slovaks and Ruthenians fit in the Eastern European metapopulation defined in the Y chromosome haplotype reference database.

    2011-04-01

    Projecting technology performance evolution has been improving over the years. Reliable quantitative forecasting methods have been developed that project the growth, diffusion, and performance of technology in time, including projecting technology substitutions, saturation levels, and performance improvements. These forecasts can be applied at the early stages of space technology planning to better predict available future technology performance, assure the successful selection of technology, and improve technology systems management strategy. Often what is published as a technology forecast is simply scenario planning, usually made by extrapolating current trends into the future, with perhaps some subjective insight added. Typically, the accuracy of such predictions falls rapidly with distance in time. Quantitative technology forecasting (QTF), on the other hand, includes the study of historic data to identify one of or a combination of several recognized universal technology diffusion or substitution patterns. In the same manner that quantitative models of physical phenomena provide excellent predictions of system behavior, so do QTF models provide reliable technological performance trajectories. In practice, a quantitative technology forecast is completed to ascertain with confidence when the projected performance of a technology or system of technologies will occur. Such projections provide reliable time-referenced information when considering cost and performance trade-offs in maintaining, replacing, or migrating a technology, component, or system. This paper introduces various quantitative technology forecasting techniques and illustrates their practical application in space technology and technology systems management.

    The concept of human settlements technology (HST) is described and applied to the unique needs of developing countries having different cultural and climatic conditions. These countries are experiencing rapid growth in population, and appropriate technology should not be assumed to be the same as that used in industrialized counties in temperate climates. A new world order is asking that emerging countries define their own living patterns and determine which technologies are suitable for their whole population's needs rather than limiting modern technology to an elite. The author describes how unconventional, but creative, energy can be tapped for housing construction that is low-cost, self-sufficient, and easy to service. A plurality of life styles in tune with the ecosystem could be adopted, but this will require politicians and architects to approach eco-design as a creative rather than imitative process.

    2013-01-01

    Human space exploration has always been heavily influenced by goals to achieve a specific mission on a specific schedule. This approach drove rapid technology development, the rapidity of which adds risks as well as provides a major driver for costs and cost uncertainty. The National Aeronautics and Space Administration (NASA) is now approaching the extension of human presence throughout the solar system by balancing a proactive yet less schedule-driven development of technology with opportunistic scheduling of missions as the needed technologies are realized. This approach should provide cost effective, low risk technology development that will enable efficient and effective manned spaceflight missions. As a first step, the NASA Human Spaceflight Architecture Team (HAT) has identified a suite of critical technologies needed to support future manned missions across a range of destinations, including in cis-lunar space, near earth asteroid visits, lunar exploration, Mars moons, and Mars exploration. The challenge now is to develop a strategy and plan for technology development that efficiently enables these missions over a reasonable time period, without increasing technology development costs unnecessarily due to schedule pressure, and subsequently mitigating development and mission risks. NASA's Johnson Space Center (JSC), as the nation s primary center for human exploration, is addressing this challenge through an innovative approach in allocating Internal Research and Development funding to projects. The HAT Technology Needs (TechNeeds) Database has been developed to correlate across critical technologies and the NASA Office of Chief Technologist Technology Area Breakdown Structure (TABS). The TechNeeds Database illuminates that many critical technologies may support a single technical capability gap, that many HAT technology needs may map to a single TABS technology discipline, and that a single HAT technology need may map to multiple TABS technology

    Full Text Available Drawing on the field research conducted in the Serbian community in Szigetcsép, Hungary, the paper examines interlocutors’ oral discourse on interethnic marriages. Until the Second World War, the Serbs in Hungary, rural communities in particular, mainly practised endogamy. In the post-war era, however, they tended to be among the minority groups with the highest rate of exogamic marriages. Conse­quently, the interviewees established discourse links between “interethnic marriages”, “loss of native language” and “fear of identity loss”. The analytical focus is on the interlocutors’ internal dialogism between the authoritative word of the ancestors and autobiographical assertions.

    The Center for Environmental Technology's (CET) mission is to provide a fully integrated system for accelerated evaluation, development, commercialization, and public acceptance of creative environmental solutions which match the foremost demands in today's environmentally sensitive world. In short, CET will create a means to provide quick, effective solutions for environmental needs. To meet this mission objective, CET has created a unique and innovative approach to eliminating the usual barriers in developing and testing environmental technologies. The approach paves the way for these emerging, cutting-edge technologies by coordinating environmental restoration and waste management activities of industry, universities, and the government to: efficiently and effectively transfer technology to these users, provide market-driven, cost-effective technology programs to the public and DOE, and aid in developing innovative ideas by initiating efforts between DOE facilities and private industry. The central part to this mission is selecting and evaluating specific innovative technologies for demonstration and application at United States Department of Energy (DOE) installations. The methodology and criteria used for this selection, which is called the CET Innovative Technology Screening Process, is the subject of this paper. The selection criteria used for the screening process were modeled after other DOE technology transfer programs and were further developed by CET's Technology Screening and Evaluation Board (TSEB). The process benefits both CET and the proposing vendors by providing objective selection procedures based on predefined criteria. The selection process ensures a rapid response to proposing vendors, all technologies will have the opportunity to enter the selection process, and all technologies are evaluated on the same scale and with identical criteria

    This DOE-NE Advanced Small Modular Reactor (AdvSMR) regulatory technology development plan (RTDP) will link critical DOE nuclear reactor technology development programs to important regulatory and policy-related issues likely to impact a “critical path” for establishing a viable commercial AdvSMR presence in the domestic energy market. Accordingly, the regulatory considerations that are set forth in the AdvSMR RTDP will not be limited to any one particular type or subset of advanced reactor technology(s) but rather broadly consider potential regulatory approaches and the licensing implications that accompany all DOE-sponsored research and technology development activity that deal with commercial non-light water reactors. However, it is also important to remember that certain “minimum” levels of design and safety approach knowledge concerning these technology(s) must be defined and available to an extent that supports appropriate pre-licensing regulatory analysis within the RTDP. Final resolution to advanced reactor licensing issues is most often predicated on the detailed design information and specific safety approach as documented in a facility license application and submitted for licensing review. Because the AdvSMR RTDP is focused on identifying and assessing the potential regulatory implications of DOE-sponsored reactor technology research very early in the pre-license application development phase, the information necessary to support a comprehensive regulatory analysis of a new reactor technology, and the resolution of resulting issues, will generally not be available. As such, the regulatory considerations documented in the RTDP should be considered an initial “first step” in the licensing process which will continue until a license is issued to build and operate the said nuclear facility. Because a facility license application relies heavily on the data and information generated by technology development studies, the anticipated regulatory

    2013-01-01

    Objectives Health information technology (HIT) research findings suggested that new healthcare technologies could reduce some types of medical errors while at the same time introducing classes of medical errors (i.e., technology-induced errors). Technology-induced errors have their origins in HIT, and/or HIT contribute to their occurrence. The objective of this paper is to review current trends in the published literature on HIT safety. Methods A review and synthesis of the medical and life sciences literature focusing on the area of technology-induced error was conducted. Results There were four main trends in the literature on technology-induced error. The following areas were addressed in the literature: definitions of technology-induced errors; models, frameworks and evidence for understanding how technology-induced errors occur; a discussion of monitoring; and methods for preventing and learning about technology-induced errors. Conclusions The literature focusing on technology-induced errors continues to grow. Research has focused on the defining what an error is, models and frameworks used to understand these new types of errors, monitoring of such errors and methods that can be used to prevent these errors. More research will be needed to better understand and mitigate these types of errors. PMID:23882411

  6. Copper Cable Recycling Technology. Innovative Technology Summary Report

    International Nuclear Information System (INIS)

    2001-01-01

    The United States Department of Energy (DOE) continually seeks safer and more cost-effective technologies for use in deactivation and decommissioning (D and D) of nuclear facilities. The Deactivation and Decommissioning Focus Area (DDFA) of the DOE's Office of Science and Technology (OST) sponsors large-scale demonstration and deployment projects (LSDDPs). At these LSDDPs, developers and vendors of improved or innovative technologies showcase products that are potentially beneficial to the DOE's projects and to others in the D and D community. Benefits sought include decreased health and safety risks to personnel and the environment, increased productivity, and decreased costs of operation. The Idaho National Engineering and Environmental Laboratory (INEEL) generated a list of statements defining specific needs and problems where improved technology could be incorporated into ongoing D and D tasks. One such need is to reduce the volume of waste copper wire and cable generated by D and D. Deactivation and decommissioning activities of nuclear facilities generates hundreds of tons of contaminated copper cable, which are sent to radioactive waste disposal sites. The Copper Cable Recycling Technology separates the clean copper from contaminated insulation and dust materials in these cables. The recovered copper can then be reclaimed and, more importantly, landfill disposal volumes can be reduced. The existing baseline technology for disposing radioactively contaminated cables is to package the cables in wooden storage boxes and dispose of the cables in radioactive waste disposal sites. The Copper Cable Recycling Technology is applicable to facility decommissioning projects at many Department of Energy (DOE) nuclear facilities and commercial nuclear power plants undergoing decommissioning activities. The INEEL Copper Cable Recycling Technology Demonstration investigated the effectiveness and efficiency to recycle 13.5 tons of copper cable. To determine the effectiveness

  9. Science, technology, and pedagogy: Exploring secondary science teachers' effective uses of technology

    Science.gov (United States)

    Guzey, Siddika Selcen

    Technology has become a vital part of our professional and personal lives. Today we cannot imagine living without many technological tools such as computers. For the last two decades technology has become inseparable from several areas, such as science. However, it has not been fully integrated into the field of education. The integration of technology in teaching and learning is still challenging even though there has been a historical growth of Internet access and available technology tools in schools (U.S. Department of Education, National Center for Education Statistics, 2006). Most teachers have not incorporated technology into their teaching for various reasons such as lack of knowledge of educational technology tools and having unfavorable beliefs about the effectiveness of technology on student learning. In this study, three beginning science teachers who have achieved successful technology integration were followed to investigate how their beliefs, knowledge, and identity contribute to their uses of technology in their classroom instruction. Extensive classroom observations and interviews were conducted. The findings demonstrate that the participating teachers are all intrinsically motivated to use technology in their teaching and this motivation allows them to enjoy using technology in their instruction and keeps them engaged in technology use. These teachers use a variety of technology tools in their instruction while also allowing students to use them, and they posit a belief set in favor of technology. The major findings of the study are displayed in a model which indicates that teachers' use of technology in classroom instruction was constructed jointly by their technology, pedagogy, and content knowledge; identity; beliefs; and the resources that are available to them and that the internalization of the technology use comes from reflection. The study has implications for teachers, teacher educators, and school administrators for successful technology

  12. Digital Actuator Technology

    Energy Technology Data Exchange (ETDEWEB)

    Ken Thomas; Ted Quinn; Jerry Mauck; Richard Bockhorst

    2014-09-01

    There are significant developments underway in new types of actuators for power plant active components. Many of these make use of digital technology to provide a wide array of benefits in performance of the actuators and in reduced burden to maintain them. These new product offerings have gained considerable acceptance in use in process plants. In addition, they have been used in conventional power generation very successfully. This technology has been proven to deliver the benefits promised and substantiate the claims of improved performance. The nuclear industry has been reluctant to incorporate digital actuator technology into nuclear plant designs due to concerns due to a number of concerns. These could be summarized as cost, regulatory uncertainty, and a certain comfort factor with legacy analog technology. The replacement opportunity for these types of components represents a decision point for whether to invest in more modern technology that would provide superior operational and maintenance benefits. Yet, the application of digital technology has been problematic for the nuclear industry, due to qualification and regulatory issues. With some notable exceptions, the result has been a continuing reluctance to undertake the risks and uncertainties of implementing digital actuator technology when replacement opportunities present themselves. Rather, utilities would typically prefer to accept the performance limitations of the legacy analog actuator technologies to avoid impacts to project costs and schedules. The purpose of this report is to demonstrate that the benefits of digital actuator technology can be significant in terms of plant performance and that it is worthwhile to address the barriers currently holding back the widespread development and use of this technology. It addresses two important objectives in pursuit of the beneficial use of digital actuator technology for nuclear power plants: 1. To demonstrate the benefits of digital actuator

    Full Text Available In the article divorce the concepts of engineering and technology. Designated four stages of technological development: the fi rst phase — “pilot technique”, it is characterized by magical conceptualization, the second — engineering (rational conceptualization, third design, fourth technology. For technical equipment is characterized by four features: technology is the artifacts, the technique can be considered as a “social body” of a person or society, technology is a useful way to use the forces of nature, and fi nally, the mediation in the form of tools, machines, and material environment that allows you to implement the ideas of man. It is argued that the conceptualization of technology is the essential characteristic of the concept. If you write, for example, about the technology of the Neolithic age or era of construction of the Egyptian pyramids, then we are talking about retrospective interpretation, from the point of view of modern understanding of technology. It’s not useless, for example, to determine preconditions of formation technology, but in terms of thinking creates problems and contradictions. The author argues that technology develops in the second half of the eighteenth century as a new reality, which describes the industrial activities in language operations and their conditions of division of labor and management. At the same time, technology is being characterized by the installation of quality, savings, standardization, and rational description of the production processes, their optimization for the training of new technologists.

  19. Cooperative technology development: An approach to advancing energy technology

    International Nuclear Information System (INIS)

    Stern, T.

    1989-09-01

    Technology development requires an enormous financial investment over a long period of time. Scarce national and corporate resources, the result of highly competitive markets, decreased profit margins, wide currency fluctuations, and growing debt, often preclude continuous development of energy technology by single entities, i.e., corporations, institutions, or nations. Although the energy needs of the developed world are generally being met by existing institutions, it is becoming increasingly clear that existing capital formation and technology transfer structures have failed to aid developing nations in meeting their growing electricity needs. This paper will describe a method for meeting the electricity needs of the developing world through technology transfer and international cooperative technology development. The role of nuclear power and the advanced passive plant design will be discussed. (author)

    Estimating technological progress of emerging technologies such as renewables and clean coal technologies becomes important for designing low carbon energy systems in future and drawing effective energy policies. Learning curve is an analytical approach for describing the decline rate of cost and production caused by technological progress as well as learning. In the study, a bottom-up energy-economic model including an endogenous technological learning function has been designed. The model deals with technological learning in energy conversion technologies and its spillover effect. It is applied as a feasibility study of clean coal technologies such as IGCC (Integrated Coal Gasification Combined Cycle) and IGFC (Integrated Coal Gasification Fuel Cell System) in Japan. As the results of analysis, it is found that technological progress by learning has a positive impact on the penetration of clean coal technologies in the electricity market, and the learning model has a potential for assessing upcoming technologies in future.

  2. Sustainability of University Technology Transfer: Mediating Effect of Inventor’s Technology Service

    Directory of Open Access Journals (Sweden)

    2018-06-01

    Full Text Available Based on the perspective of knowledge transfer and the technology acceptance model (TAM, this paper constructs a university technology transfer sustainable development model that considers the inventor’s technology service from the perspective of the long-term cooperation of enterprise, and analyzes the mediating effect of the inventor’s technology service on university technology transfer sustainability. By using 270 questionnaires as survey data, it is found that the availability of an inventor’s technology service has a significant positive impact on the attitude tendency and practice tendency of enterprise long-term technological cooperation; enterprise technology absorption capacity and trust between a university and an enterprise also have significant influence on an inventor’s technical service availability. Therefore, the inventor’s technology service acts as a mediator in the relationship between university technology transfer sustainability and influence factors. Universities ought to establish the technology transfer model, which focuses on the inventor’s tacit knowledge transfer service, and promotes the sustainable development of the university.

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology '90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology '90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information. Separate papers were prepared for appropriate sections of this report.

  5. 1H NMR spectrum of the native human insulin monomer. Evidence for conformational differences between the monomer and aggregated forms.

    Roy, M; Lee, R W; Brange, J; Dunn, M F

    1990-04-05

    The effects of high dilution on the 1H Fourier transform NMR spectrum of native human insulin at pH* 8.0 and 9.3 have been examined at 500 MHz resolution. The dependence of the spectrum on concentration and comparison with the spectrum of a biologically highly potent monomeric insulin mutant (SerB9----Asp) establish that at 36 microM (pH* 9.3) or 18 microM (pH* 8) and no added buffer or salts, human insulin is monomeric. Under these conditions of dilution, ionic strength, and pH*, human insulin and the SerB9----Asp mutant exhibit nearly identical 1H NMR spectra. At higher concentrations (i.e. greater than 36 microM to 0.91 mM), native human insulin dimerizes, and this aggregation causes a change in insulin conformation. Although there are many changes in the spectrum, the TyrB26 ring H3,5 proton signals located at 6.63 ppm and the methyl signal located at 0.105 ppm (characteristics of monomeric insulin) are particularly distinct signatures of the conformation change that accompanies dimerization. Magnetization transfer experiments show that the 0.105 ppm methyl signal shifts downfield to a new position at 0.45 ppm. We conclude that the 0.105 ppm methyl signal is due to a conformation in which a Leu methyl group is centered over and in van der Waals contact with the ring of an aromatic side chain. Dimerization causes a conformation change that alters this interaction, thereby causing the downfield shift. Nuclear Overhauser studies indicate that the methyl group involved is located within a cluster of aromatic side chains and that the closest ring-methyl group interaction is with the ring of PheB24.

    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

    Technology is not an end in itself, but a means to an end for human existence. If it does not serve this purpose it must be adapted or changed. Criticism of technology is necessary in view of the various positive and negative consequences of technology, it must however be based on judgement and sense of responsibility. It is however often claimed that technology and industry are the tools of the evil and that the technical intelligentsia do not feel responsible for psychological, social and political consequences of their doing. By contributions of several authors and of different periods this book elucidates the often grotesque contradictions between demagogic accusation of technology and the reality of technology; this book presents principal considerations on an acceptable assessment of technology.

    This study analyzes how a group of ‘mediators’ in a large, multinational company adapted a computer-mediated communication technology (a ‘virtual workspace’) to the organizational context (and vice versa) by modifying features of the technology, providing ongoing support for users, and promoting...... appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, this study also indicates that the process...... of technology-use mediation is more complex and indeterminate than earlier literature suggests. In particular, we want to draw attention to the fact that advanced computer-mediated communication technologies are equivocal and that technology-use mediation consequently requires ongoing sensemaking (Weick 1995)....

    I offer an interpretation of hackers' technological choices through a theoretical framework of critique and recuperation in technological cycles, building on prior research that brings the pragmatic sociology of Boltanski and Chiapello to bear on matters in Science and Technology Studies. I argue that contextualizing technology choices in the development of capitalism through innovation illuminates their political significance. I start with the counterintuitive observation that some browser extensions popular with hackers, like RequestPolicy, make it considerably harder for them to look at websites. This observation showcases the Luddite aspects of hackerdom, in that they are willing to 'break' popular websites that would otherwise cheat on the user. In line with an undercurrent of hacker studies, in this case study I find hackers fighting technological progress they see as social decline.

    Although eHealth technologies offer an enormous potential to improve healthcare, the knowledge about key determinants of acceptance for eHealth technology is restricted. While the underlying technology of eHealth technologies and Information and Communication technology (ICT) is quite similar, utilization contexts and using motives are quite different. In order to explore the role of technology type on acceptance, we contrasted central application characteristics of both technology types using the scenario technique. A questionnaire was administered (n = 104) measuring individual variables (age, gender) and attitudes regarding an eHealth application (blood sugar meter) in contrast to an ICT device (Personal Digital Assistant, PDA). Older users basically approved the utilization of health-related technologies and perceived lower usability barriers. In addition, we identified main utilization motives of eHealth technology and technology-specific acceptance patterns, especially regarding issues of data safety in the eHealth context. Effects of age and gender in acceptance ratings suggest a differential perspective on eHealth acceptance. Finally, practical interventions were derived in order to support eHealth device design and to promote acceptance of eHealth technology.

  18. Technology transfer and development: a preliminary look at Chinese technology in Guyana

    Energy Technology Data Exchange (ETDEWEB)

    Long, F

    1982-05-01

    Technology is regarded as a vital ingredient for development. Since developing countries can hardly fill their technological requirements indigenously, such countries tend to acquire the bulk of technology applied to their production systems from abroad. However, the transfer of technology tends to be associated with a series of problems: foreign exchange, inappropriateness, the generation of limited inter-sectorial linkages, limited use of raw materials, and other inputs associated with technology dependency. The study points to the fact that technology transfer need not necessarily be associated with the disadvantages identified in the literature. The study which essentially looks at the use of Chinese technology in clay-brick manufacturing in Guyana, shows that the country was able to reap several development benefits from the technology-transfer arrangement. At the same time, certain problems arising from the technology-transfer package such as the transfer of critical skills in key areas of production, and maintenance and servicing, are discussed. But these, the author argues, are not a function of restrictive conditions found in technology-transfer clauses, but rather of improper technology-transfer management. 2 tables.

  1. Inter-technology knowledge spillovers for energy technologies

    International Nuclear Information System (INIS)

    Nemet, Gregory F.

    2012-01-01

    Both anecdotal evidence and the innovation literature indicate that important advances in energy technology have made use of knowledge originating in other technological areas. This study uses the set of U.S. patents granted from 1976 to 2006 to assess the role of knowledge acquired from outside each energy patent's technological classification. It identifies the effect of external knowledge on the forward citation frequency of energy patents. The results support the claim above. Regression coefficients on citations to external prior art are positive and significant. Further, the effect of external citations is significantly larger than that of other types of citations. Conversely, citations to prior art that is technologically near have a negative effect on forward citation frequency. These results are robust across several alternative specifications and definitions of whether each flow of knowledge is external. Important energy patents have drawn heavily from external prior art categorized as chemical, electronics, and electrical; they cite very little prior art from computers, communications, and medical inventions.

    Pilotto, Alberto; Boi, Raffaella; Petermans, Jean

    2018-03-13

    Recently, the interest of industry, government agencies and healthcare professionals in technology for aging people has increased. The challenge is whether technology may play a role in enhancing independence and quality of life and in reducing individual and societal costs of caring. Information and communication technologies, i.e. tools aimed at communicating and informing, assistive technologies designed to maintain older peoples' independence and increasing safety, and human-computer interaction technologies for supporting older people with motility and cognitive impairments as humanoid robots, exoskeletons, rehabilitation robots, service robots and companion-type are interdisciplinary topics both in research and in clinical practice. The most promising clinical applications of technologies are housing and safety to guarantee older people remaining in their own homes and communities, mobility and rehabilitation to improve mobility and gait and communication and quality of life by reducing isolation, improve management of medications and transportation. Many factors impair a broad use of technology in older age, including psychosocial and ethical issues, costs and fear of losing human interaction. A substantial lack of appropriate clinical trials to establish the clinical role of technologies to improve physical or cognitive performances and/or quality of life of subjects and their caregivers may suggest that the classical biomedical research model may not be the optimal choice to evaluate technologies in older people. In conclusion, successful technology development requires a great effort in interdisciplinary collaboration to integrate technologies into the existing health and social service systems with the aim to fit into the older adults' everyday life.

  8. When technology, science and culture meet: insights from ancient Chinese technology

    Science.gov (United States)

    Lee, Yeung Chung

    2017-10-01

    This paper draws together two important agendas in science education. The first is making science education more inclusive such that students from non-Western or indigenous cultures can benefit from culturally relevant curricula. The second is integrating technology into the curriculum under the umbrella of Science-Technology-Society (STS) education to embrace the social aspects of science, with technology serving as a bridge. The advancement of the first agenda is hindered by the pursuance by both Western and non-Western societies of narrow cultural and practical goals without considering the development of science and technology from a cross-cultural perspective. The second agenda is limited by the misconception that technology is applied science, leading to the exclusion from STS discussions of pre-science or indigenous technologies developed by non-Western cultures. Through selected case studies of the evolution of Chinese traditional technologies and their interaction with science, this paper offers a perspective from the Far East, and argues for situating culturally responsive science education in broader historical and cross-cultural contexts to acknowledge the multi-cultural contributions to science and technology. A form of cross-cultural STS education is advanced, encompassing the cultural basis of technological developments, technology diffusion, interactions of traditional technology with science, and the potential development of traditional or indigenous technologies. This approach provides a bridge between the existing universal science education paradigm promoted in the West and the different forms of multi-cultural education advocated by indigenous science educators. To translate theory into practice, a conceptual framework is proposed in which the essential transdisciplinary knowledge base, curricular goals, and pedagogical approaches are embedded.

    There is a great potential in Serbia for energy conservation and new technology after years of war. In practice, Serbia has lost 10 - 15 years and much must be rebuilt from the ground. Norway is working with Serbia to develop Serb know-how in the field of energy conservation. This involves consultative advice to the energy department in Belgrade for the development of a new energy act and the preparation of an energy report to the parliamentary assembly. There is also cooperation with the universities in order to establish four regional centres for energy conservation, and with several industrial companies to develop and implement definite investment projects. In Norway, several models for local energy conservation centres have been tried out during the last 20 years. These centres used to be financed by a mark-up on the electric tariff and they offered subsidized energy conservation counselling to the energy consumers. However, this did not work out well and the centres were removed from the electricity companies and now have to compete with other consultants to deliver the demanded services to the industries and private consumers. This false step will not be repeated in Serbia, where the energy conservation centres will be independent, commercial centres from the beginning. In developing this system, experience is drawn upon from Norwegian projects in many of the major cities in North-Western Russia.

    Heavy vacuum gas oil (HVGO) is a complex and viscous hydrocarbon stream that is produced as the bottom side product from the vacuum distillation units in petroleum refineries. HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green approaches for valorization and upgrading of HVGO. The Pseudomonas aeruginosa AK6U strain grew on 20% v/v of HVGO as a sole carbon and sulfur source. It produced rhamnolipid biosurfactants in a growth-associated mode with a maximum crude biosurfactants yield of 10.1 g l -1 , which reduced the surface tension of the cell-free culture supernatant to 30.6 mN m -1 within 1 week of incubation. The rarely occurring dirhamnolipid Rha-Rha-C 12 -C 12 dominated the congeners' profile of the biosurfactants produced from HVGO. Heavy vacuum gas oil was recovered from the cultures and abiotic controls and the maltene fraction was extracted for further analysis. Fractional distillation (SimDist) of the biotreated maltene fraction showed a relative decrease in the high-boiling heavy fuel fraction (BP 426-565 °C) concomitant with increase in the lighter distillate diesel fraction (BP 315-426 °C). Analysis of the maltene fraction revealed compositional changes. The number-average (Mn) and weight-average (Mw) molecular weights, as well as the absolute number of hydrocarbons and sulfur heterocycles were higher in the biotreated maltene fraction of HVGO. These findings suggest that HVGO can be potentially exploited as a carbon-rich substrate for production of the high-value biosurfactants by P. aeruginosa AK6U and to concomitantly improve/upgrade its chemical composition. © 2017 The Authors.

  12. Bioremediation of Petroleum Hydrocarbon Contaminated Sites

    Energy Technology Data Exchange (ETDEWEB)

    2009-03-30

    Bioremediation has been widely applied in the restoration of petroleum hydrocarbon-contaminated. Parameters that may affect the rate and efficiency of biodegradation include temperature, moisture, salinity, nutrient availability, microbial species, and type and concentration of contaminants. Other factors can also affect the success of the bioremediation treatment of contaminants, such as climatic conditions, soil type, soil permeability, contaminant distribution and concentration, and drainage. Western Research Institute in conjunction with TechLink Environmental, Inc. and the U.S. Department of Energy conducted laboratory studies to evaluate major parameters that contribute to the bioremediation of petroleum-contaminated drill cuttings using land farming and to develop a biotreatment cell to expedite biodegradation of hydrocarbons. Physical characteristics such as soil texture, hydraulic conductivity, and water retention were determined for the petroleum hydrocarbon contaminated soil. Soil texture was determined to be loamy sand to sand, and high hydraulic conductivity and low water retention was observed. Temperature appeared to have the greatest influence on biodegradation rates where high temperatures (>50 C) favored biodegradation. High nitrogen content in the form of ammonium enhanced biodegradation as well did the presence of water near field water holding capacity. Urea was not a good source of nitrogen and has detrimental effects for bioremediation for this site soil. Artificial sea water had little effect on biodegradation rates, but biodegradation rates decreased after increasing the concentrations of salts. Biotreatment cell (biocell) tests demonstrated hydrocarbon biodegradation can be enhanced substantially when utilizing a leachate recirculation design where a 72% reduction of hydrocarbon concentration was observed with a 72-h period at a treatment temperature of 50 C. Overall, this study demonstrates the investigation of the effects of

    At present, the development of high technology has opened a new chapter in world's history of science and technology. This review describes the great impact of physics on high technology in six different fields (energy technology, new materials, information technology, biotechnology, space technology, and Ocean technology). It is shown that the new concepts and new methods created in physics and the special conditions and measurements established for physics researches not only deepen human's knowledge about nature but also point out new directions for engineering and technology. The achievements in physics have been more and more applied to high technology, while the development of high technology has explored some new research areas and raised many novel, important projects for physics. Therefore, it is important for us to strengthen the research on these major problems in physics

  14. Advanced manufacturing: Technology diffusion

    Energy Technology Data Exchange (ETDEWEB)

    Tesar, A.

    1995-12-01

    In this paper we examine how manufacturing technology diffuses rom the developers of technology across national borders to those who do not have the capability or resources to develop advanced technology on their own. None of the wide variety of technology diffusion mechanisms discussed in this paper are new, yet the opportunities to apply these mechanisms are growing. A dramatic increase in technology diffusion occurred over the last decade. The two major trends which probably drive this increase are a worldwide inclination towards ``freer`` markets and diminishing isolation. Technology is most rapidly diffusing from the US In fact, the US is supplying technology for the rest of the world. The value of the technology supplied by the US more than doubled from 1985 to 1992 (see the Introduction for details). History shows us that technology diffusion is inevitable. It is the rates at which technologies diffuse to other countries which can vary considerably. Manufacturers in these countries are increasingly able to absorb technology. Their manufacturing efficiency is expected to progress as technology becomes increasingly available and utilized.

    Food irradiation is over 100 years old, with the original patent for X-ray treatment of foods being issued in early 1905, 20 years after there discovery by W. C. Roentgen in 1885. Since then, food irradiation technology has become one of the most extensively studied food processing technologies in the history of mankind. Unfortunately, it is the one of the most misunderstood technologies with the result that there are rampant misunderstandings of the core technology, the ideal applications, and how to use it effectively to derive the maximum benefits. There are a number of books, book chapters, and review articles that provide overviews of this technology [25, 32, 36, 39]. Over the last decade or so, the technology has come into greater focus because many of the other pathogen intervention technologies have been unable to provide sustainable solutions on how to address pathogen contamination in foods. The uniqueness of food irradiation is that this technology is a non-thermal food processing technology, which unto itself is a clear high-value differentiator from other competing technologies.

    Finland has wide experience in applications of various combustion technologies and fuels and in supplying energy to industry and municipalities. Furthermore, combustion hardware and equipment are amongst our most important export products. Above all, fluidized bed boilers, recovery boilers for pulp mills and heavy diesel engines and diesel power plants have achieved excellent success in the world markets. Exports of these products alone have amounted to several billions of Finnish marks of annual sales in recent years. Within modern combustion technology, the objective is to control flue gas emissions as far as possible in the process itself, thus doing away with the need for the separate scrubbing of flue gases. To accomplish this it has been necessary to conduct a large amount of research on the details of the chemistry of combustion emissions and the flows in furnaces and engine cylinders. A host of completely new products are being developed for the combustion technology field. The LIEKKI programme has been particularly interested in so-called combined-cycle processes based on pressurized fluidized bed technology

    The OG21 Technology Target Area 1 (TTA 1) group has produced a strategy for 'Environmental Technology for the Future'. A key aim of this work is to ensure that the operators on the Norwegian Continental Shelf (NCS) remain in a leading position with respect to environmental performance, while contributing to optimised resource recovery and value creation. This strategy focuses on environmental technology, which includes hardware, methods, software and knowledge. The TTA 1 group has agreed on a common vision: 'Norwegian oil and gas activities shall be leading in environmental performance, and Norway shall have the world leading knowledge and technology cluster within environmental technologies to support the zero harmful impact goals of the oil and gas industry.' Priorities have been made with emphasis on gaps that are considered most important to close and that will benefit from public research and development funding either for initialisation (primarily via the Petromaks and Climit programs) or acceleration (via Petromaks / Climit and particularly Demo 2000 where demonstration or piloting is required). The priorities aim to avoid technology gaps that are expected to be closed adequately through existing projects / programs or which are covered in other TTA strategies. The priority areas as identified are: Environmental impact and risk identification / quantification for new areas: Make quality assured environmental baseline data available on the web. Develop competence necessary to quantify and monitor the risks and risk reductions to the marine environment in new area ecosystems; Carbon capture and storage: Quantify environmental risks and waste management issues associated with bi-products from carbon capture processes and storage solutions. Develop and demonstrate effective carbon storage risk management, monitoring and mitigation technologies.

    Nuclear power is firmly established in many developed countries'energy policies and is being adopted by emerging nations as an attractive way of gaining energy self sufficiency. The early users of nuclear power had to develop the technology that they needed, which now, through increasing world wide experience, has been rationalised to meet demanding economic and environmental pressures. These justifiable pressures, can lead to existing suppliers of nuclear services to consider changing to more appropriate technologies and for new suppliers to consider licensing proven technology rather then incurring the cost of developing new alternatives. The transfer of technology, under license, is made more straight forward if the owner conveniently groups appropriate technology into packages. This paper gives examples of 'Technology Packages' and suggests criteria for the specification, selection and contractual requirements to ensure successful licensing

  16. Improvement of simultaneous Cr(VI) and phenol removal by an immobilised bacterial consortium and characterisation of biodegradation products.

    2017-07-25

    Microbial bioremediation emerged some decades ago as an eco-friendly technology to restore polluted sites. Traditionally, the search for microorganisms suitable for bioremediation has been based on the selection of isolated strains able to remove a specific type of pollutant. However, this strategy has now become obsolete, since co-pollution is a global reality. Thus, current studies attempt to find bacterial cultures capable of coping with a mixture of organic and inorganic compounds. In this sense, the bacterial consortium SFC 500-1 has demonstrated efficiency for Cr(VI) and phenol removal, both of which are found in many industrial wastewaters. In the present study, the ability of SFC 500-1 for simultaneous removal was improved through its entrapment in a Ca-alginate matrix. This strategy led to an increased removal of Cr(VI), which was partially reduced to Cr(III). Immobilised cells were able to tolerate and degrade phenol up to 1,500mg/l at high rates, forming catechol and cis,cis-muconate as oxidation intermediates. Successful removal potential through 5 cycles of reuse, as well as after long-term storage, was another important advantage of the immobilised consortium. These characteristics make SFC 500-1 an interesting system for potential application in the biotreatment of co-polluted effluents. Copyright © 2017. Published by Elsevier B.V.

  17. The concomitant use of indigenous soil bacteria and fungi to enhance the bioremediation of refinery waste

    2001-07-01

    Usually, the use of indigenous soil bacteria for the remediation of petroleum-contaminated soils was restricted to the biodegradation of low-molecular weight petroleum hydrocarbons such as gasoline, diesel, fuel oil and jet fuel. The advantage of using indigenous microorganisms is the minimization of the impact of the treatment on the microbial diversity. As a rule,these techniques are also well accepted by the public. Other studies have shown that fungi is successful for the bioremediation of heavier-weight contaminants. The concomitant transformation of low-molecular weight and heavier recalcitrant oil fractions to inorganic and humic form can be accomplished with the concomitant action of bacteria and fungi. The development of a soil biotreatment program using this concomitant technique was performed by PETROBRAS Petroleo Brasileiro S.A. - Refinaria Presidente Getulio Vargas in conjunction with the Universidade Federal do Parana. It resulted in a full-scale technology that allows the degradation of oil waste. Approximately two years of treatment are required to achieve the desired results. The use of standard analytical methods and bioindicators used on the treated soil indicated that the treated soil met the standards for agricultural soil quality. A recent oil spill occurred in Araucaria, Brazil and a bioremediation area was inoculated, and to date the results prove the beneficial effects to be derived from the use of inoculation. Some results were presented in table format. 3 tabs.

    1997-12-01

    This report describes a pilot study involving treatment of contaminated groundwater at a former manufactured gas plant site on the eastern seaboard of the US. The work was performed in order to provide the design basis for a full-scale groundwater extraction and treatment system at the site, as well as to develop a generic approach to selection of groundwater treatment sequences at other MGP sites. It included three main components: hydrogeologic investigations, bench-scale treatability studies, and pilot-scale treatability studies. Technologies evaluated in bench-scale work included gravity settling, filtration, and dissolved air flotation (DAF) for primary treatment of nonaqueous phase materials; biological degradation, air stripping, and carbon adsorption for secondary treatment of dissolved organics; and carbon adsorption as tertiary treatment of remaining dissolved contaminants. Pilot-scale studies focused on collecting system performance data fore three distinct levels of contamination. Two treatment trains were evaluated. One consisted of DAF, fluidized-bed biotreatment, and filtration plus carbon adsorption; the other used the same steps except to substitute air stripping for fluidized bed treatment. The final effluents produced by both treatment sequences were similar and demonstrated complete treatment of the groundwater. Besides detailing system design and performance for the treatability studies, the report includes an analysis of groundwater treatment applications to MGP sites in general, including a discussion of capital and operating costs

    Upflow, anaerobic, fixed-bed, activated charcoal biotreatment columns capable of operating at free cyanide concentrations of greater than 100 mg liter-1 with a hydraulic retention time of less than 48 h were developed. Methanogenesis was maintained under a variety of feed medium conditions which included ethanol, phenol, or methanol as the primary reduced carbon source. Under optimal conditions, greater than 70% of the inflow free cyanide was removed in the first 30% of the column height. Strongly complexed cyanides were resistant to removal. Ammonia was the nitrogen end product of cyanide transformation. In cell material removed from the charcoal columns, [14C]bicarbonate was the major carbon end product of [14C]cyanide transformation.

    2006-01-01

    NASA's In-space Propulsion (ISP) Technology Project is developing new propulsion technologies that can enable or enhance near and mid-term NASA science missions. The Solar Electric Propulsion (SEP) technology area has been investing in NASA s Evolutionary Xenon Thruster (NEXT), the High Voltage Hall Accelerator (HiVHAC), lightweight reliable feed systems, wear testing, and thruster modeling. These investments are specifically targeted to increase planetary science payload capability, expand the envelope of planetary science destinations, and significantly reduce the travel times, risk, and cost of NASA planetary science missions. Status and expected capabilities of the SEP technologies are reviewed in this presentation. The SEP technology area supports numerous mission studies and architecture analyses to determine which investments will give the greatest benefit to science missions. Both the NEXT and HiVHAC thrusters have modified their nominal throttle tables to better utilize diminished solar array power on outbound missions. A new life extension mechanism has been implemented on HiVHAC to increase the throughput capability on low-power systems to meet the needs of cost-capped missions. Lower complexity, more reliable feed system components common to all electric propulsion (EP) systems are being developed. ISP has also leveraged commercial investments to further validate new ion and hall thruster technologies and to potentially lower EP mission costs.

  7. Genealogies of Modern Technology

    Does modern technology differ from ancient technology and does it have a unique essence? This twofold question opens one of Martin Heidegger's most influential philosophical inquiries, The Question Concerning Technology. The answer Heidegger offers has inspired various critiques and appraisals from...... a vast number of contemporary scholars of technology.1 Heidegger's answer is traditionally thought to suggest a great difference between ancient and modern technology. However, by re-examining Heidegger's text, it is possible to discover previously ignored or misunderstood lines of thoughts that affirm...... a multi-stable interpretation of the origin of modern technology. In what follows, we shall see how The Question Concerning Technology in fact supports three different genealogies of modern technology...

    As a response to climate change and the desire to gain independence from imported fossil fuels, there is a pressure to increase the proportion of electricity from renewable sources which is one of the reasons why electricity grids are currently being turned into Smart Grids. In this paper, we focus...... on private consumers’ acceptance of having Smart Grid technology installed in their home. We analyse acceptance in a combined framework of the Technology Acceptance Model and the Norm Activation Model. We propose that individuals are only likely to accept Smart Grid technology if they assess usefulness...... in terms of a positive impact for society and the environment. Therefore, we expect that Smart Grid technology acceptance can be better explained when the well-known technology acceptance parameters included in the Technology Acceptance Model are supplemented by moral norms as suggested by the Norm...

  15. Robotics Technology Crosscutting Program. Technology summary

    International Nuclear Information System (INIS)

    1995-06-01

    The Robotics Technology Development Program (RTDP) is a needs-driven effort. A length series of presentations and discussions at DOE sites considered critical to DOE's Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the resulting robotics needs assessment revealed several common threads running through the sites: Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination and Dismantlement (D and D). The RTDP Group also realized that some of the technology development in these four areas had common (Cross Cutting-CC) needs, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT and E) process urged an additional organizational breakdown between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). These factors lead to the formation of the fifth application area for Crosscutting and Advanced Technology (CC and AT) development. The RTDP is thus organized around these application areas -- TWR, CAA, MWO, D and D, and CC and AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas

    To provide needed technologies for site remediation, the US Department of Energy's Office of Environmental Management, Office of Science and Technology (OST) is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater. The Technology Investment Decision model serves as a framework for technology management in OST. Seven technology maturation stages are used in the model. These stages run from basic research through implementation. The Innovative Technology Summary Reports (ITSRs) provide a technical synopsis of an individual technology that has been developed. An ITSR is prepared for each technology that is successfully demonstrated in the field. The information required to produce an ITSR is collected as the technology matures through the Technology Investment Decision Process. As of July 1996 there have been thirteen ITSRs completed. This paper describes those thirteen technologies

    Rosmait, Russell L.

    1996-01-01

    The development of a new space transportation system in a climate of constant budget cuts and staff reductions can be and is a difficult task. It is no secret that NASA's current launching system consumes a very large portion of NASA funding and requires a large army of people to operate & maintain the system. The new Reusable Launch Vehicle (RLV) project and it's programs are faced with a monumental task of making the cost of access to space dramatically lower and more efficient than NASA's current system. With pressures from congressional budget cutters and also increased competition and loss of market share from international agencies RLV's first priority is to develop a 'low-cost, reliable transportation to earth orbit.' One of the RLV's major focus in achieving low-cost, reliable transportation to earth orbit is to rely on the maturing of advanced technologies. The technologies for the RLV are numerous and varied. Trying to assess their current status, within the RLV development program is paramount. There are several ways to assess these technologies. One way is through the use of Technology Readiness Levels (TRL's). This project focused on establishing current (summer 95) 'worst case' TRL's for six selected technologies that are under consideration for use within the RLV program. The six technologies evaluated were Concurrent Engineering, Embedded Sensor Technology, Rapid Prototyping, Friction Stir Welding, Thermal Spray Coatings, and VPPA Welding.

    This paper measures technology (TG) and environmental efficiency technology gaps (EETGs) in 25 European countries over two distinct periods 2002 and 2008 examining the possible effect of adopted environmental regulations and the Kyoto protocol commitments on environmental efficiency technology gaps. However, the introduction of the metafrontier in our analysis puts into our discussion the role of heterogeneous technologies and its effect on the above-mentioned measures. Employing a directional distance function, we investigate whether there is an actual difference, in terms of environmental efficiency and efficiency performance, among European countries considering the technological frontiers under which they operate. The construction of individual frontiers has been realized employing a large number of variables that are highly correlated with countries' learning and absorbing capacity, new technological knowledge and using economic theory and classical frontier discrimination like developed vs. developing, North vs. South and participation in the Eurozone or not. The overall results indicate a crucial role of heterogeneous technologies for technology gaps in both periods. Moreover, a significant decrease for both measures, although in different percent, has been recorded emphasizing the key role of knowledge spillovers. -- Highlights: •We estimate technology gaps (TGs) for 25 EU countries in two distinct periods. •We estimate environmental efficiency technology gaps (EETGs). •We consider countries' technological capabilities with R&D, innovation and eco-innovation. •We test the effect of different frontier constitutions on TGs-EETGs. •We denote the specific role of knowledge spillovers

    1998-08-01

    Treatment of 2,4,6-trinitrotoluene (TNT)-contaminated soil in the Joliet Army Ammunition Plant (JAAP) soil slurry bioreactor (SSBR) eliminated detectable TNT but left trace levels of residual monoamino and diamino metabolites under some reactor operating conditions. The reduction of solvent-extractable bacterial mutagenicity in the TNT-contaminated soil was substantial and was similar to that achieved by static pile composts at the Umatilla Army Depot Activity (UMDA) field demonstration. Aquatic toxicity to Ceriodaphnia dubia from TNT in the leachates of TNT-contaminated soil was eliminated in the leachates of JAAP SSBR product soil. The toxicity of soil product leachates to Ceriodaphnia dubia was reasonably predicted using the specific toxicities of the components detected, weighted by their leachate concentrations. In samples where TNT metabolites were observed in the soil product and its leachates, this method determined that the contribution to predicted toxicity values was dominated by trace amounts of the diamino-metabolites, which are very toxic to ceriodaphnia dubia. When the SSBR operating conditions reduced the concentrations of TNT metabolites in the product soils and their leachates to undetectable concentrations, the main contributors to predicted aquatic toxicity values appeared to be molasses residues, potassium, and bicarbonate. Potassium and bicarbonate are beneficial or benign to the environment, and molasses residues are substantially degraded in the environment. Exotoxins, pathogenic bacteria, inorganic particles, ammonia, and dissolved metals did not appear to be important to soil product toxicity.

  20. The role of surgeons in identifying emerging technologies for health technology assessment.

    Science.gov (United States)

    Stafinski, Tania; Topfer, Leigh-Ann; Zakariasen, Ken; Menon, Devidas

    2010-04-01

    Health technology assessment (HTA) is a tool intended to help policy-makers decide which technologies to fund. However, given the proliferation of new technologies, it is not possible to undertake an HTA of each one before it becomes funded. Consequently, "horizon-scanning" processes have been developed to identify emerging technologies that are likely to have a substantial impact on clinical practice. Although the importance of physicians in the adoption of new technologies is well recognized, their role in horizon scanning in Canada has been limited. The purpose of this project was to pilot an approach to engage physicians, specifically surgeons, in provincial horizon-scanning activities. We invited 18 surgeons from Alberta's 2 medical schools to a horizon-scanning workshop to solicit their views on emerging technologies expected to impact surgical practice within the next 5 years and/or the importance of different attributes or characteristics of new technologies. Surgeons, regardless of specialty, identified developments designed to enhance existing minimally invasive surgical techniques, such as endoscopic, robotic and image-guided surgery. Several nonsurgical areas, including molecular genetics and nano technology, were also identified. Of the 13 technology attributes discussed, safety or risk, effectiveness and feasibility were rated as most important. Lastly, participating surgeons expressed an interest in becoming further involved in local HTA initiatives. Surgeons, as adopters and users of health technologies, represent an important and accessible information source for identifying emerging technologies for HTA. A more formal, ongoing relationship between the government, HTA and surgeons may help to optimize the use of HTA resources.

    The energy use in America's commercial and residential building sectors is large and growing. Over 38 quadrillion Btus (Quads) of primary energy were consumed in 2002, representing 39% of total U.S. energy consumption. While the energy use in buildings is expected to grow to 52 Quads by 2025, a large number of energy-related technologies exist that could curtail this increase. In recent years, improvements in such items as high efficiency refrigerators, compact fluorescent lights, high-SEER air conditioners, and improved building shells have all contributed to reducing energy use. Hundreds of other technology improvements have and will continue to improve the energy use in buildings. While many technologies are well understood and are gradually penetrating the market, more advanced technologies will be introduced in the future. The pace and extent of these advances can be improved through state and federal R&D. This report focuses on the long-term potential for energy-efficiency improvement in buildings. Five promising technologies have been selected for description to give an idea of the wide range of possibilities. They address the major areas of energy use in buildings: space conditioning (33% of building use), water heating (9%), and lighting (16%). Besides describing energy-using technologies (solid-state lighting and geothermal heat pumps), the report also discusses energy-saving building shell improvements (smart roofs) and the integration of multiple energy service technologies (CHP packaged systems and triple function heat pumps) to create synergistic savings. Finally, information technologies that can improve the efficiency of building operations are discussed. The report demonstrates that the United States is not running out of technologies to improve energy efficiency and economic and environmental performance, and will not run out in the future. The five technology areas alone can potentially result in total primary energy savings of between 2 and

    Technology alone will not be able to solve adaptation challenges, but it is likely to play an important role. As a result of the role of technology in adaptation and the importance of international collaboration for climate change, technology transfer for adaptation is a critical but understudied issue. Through an analysis of Global Environment Facility-managed adaptation projects, we find there is significantly more technology transfer occurring in adaptation projects than might be expected given the pessimistic rhetoric surrounding technology transfer for adaptation. Most projects focused on demonstration and early deployment/niche formation for existing technologies rather than earlier stages of innovation, which is understandable considering the pilot nature of the projects. Key challenges for the transfer process, including technology selection and appropriateness under climate change, markets and access to technology, and diffusion strategies are discussed in more detail.

    Full Text Available The Belgrade coup of 27 March 1941 forced Hitler to improvize the post-Yugoslav political arrangements, as in the preceding years he had sought to woo, rather than destroy, the Kingdom. For his part, just before the Axis attack Mussolini reactivated the leader of ustaša émigrés Ante Pavelić and obtained his reaffirmation of earlier commitments to cede Dalmatia to Italy. Hitler accepted the ustaša 'solution,' whereby his strategy was to let the Italians make enemies of Croats by annexationist policy, and at the same time to encourage Pavelić to terrorize the Serbs. His stratagem resulted in the chronic weakness of the occupation system. Italy did not secure longterm control over the Independent State of Croatia (NDH. Latent antra-Axis tensions provided Pavelić with the room to maneuver between Rome and Berlin and to secure a degree of autonomous action for himself - primarily in his radical attempt to solve the 'Serb question' and in the economic sphere. The NDH diplomatic apparatus reflected the ustaša power structure and the character of the state. Reports from missions abroad were sent mostly ad hoc and they were devoid of attempts to draw analytical conclusions from the news. They were invariably imbued with ungrounded optimism until the very end, likely because of the reluctance to present inferences which the political leaders would not be pleased to hear. Available archives do not indicate how the decisions affecting the NDH foreign relations were formulated; they were probably made by Pavelić and verbally conveyed to the minister. The areas of activity of the foreign ministry were twofold: consular work and the maintenance of routine relations with the Axis powers and their satellites. The consulates in the Reich were mainly dealing with the workers from the NDH in Germany, and they were actively discriminating against the Serbs who were issued one-way travel passes which prevented their return to Germany.

This expert discussion took place on 6 October 2000 at the State Pedagogical Institute Brandenburg in Ludwigsfelde-Struveshof and was conceived and organized co-operatively by the Forschungszentrum Karlsruhe, Institute for Technology Assessment and Systems Analysis, the University of Potsdam, Institute for the Theory of Work/Technology and Professor Horst Wolffgramm, Frankfurt (Oder). It was the aim of the expert discussion to compile, compare and relate the various positions in the philosophy of technology, general technology science, the history of technology and the didactics of technology of the 'conceptualisation' of technology as a basis for generally understanding technology or for a scientifically based 'image of technology' to each other, and then to make them accessible for curricula within a framework of conceiving general technical education at all school levels. The contributions are grouped according to the two main foci of the event: On the one hand they are concerned with determining a contemporary concept of technology ('Image of technology'). One of the aims is to characterize technological change from the historical-genetic perspective and in this way to access technology as a work of mankind, as an important element of our culture. At the same time it is necessary to forecast future developments or to make future paths of development visible to enable the indication of change by basic innovations. Second, on this basis and supported by educational theory, conclusions are drawn for future-oriented technical general education for all students. The main focus in this is on the linkage between goals, content and subject-specific methods. In order to enable the determination of competence of any individual

  15. Authoritative knowledge, the technological imperative and women's responses to prenatal diagnostic technologies.

    Science.gov (United States)

    McCoyd, Judith L M

    2010-12-01

    Theories about authoritative knowledge (AK) and the technological imperative have received varying levels of interest in anthropological, feminist and science and technology studies. Although the anthropological literature abounds with empirical considerations of authoritative knowledge, few have considered both theories through an empirical, inductive lens. Data extracted from an earlier study of 30 women's responses to termination for fetal anomaly are reanalyzed to consider the women's views of, and responses to, prenatal diagnostic technologies (PNDTs). Findings indicate that a small minority embrace the societal portrayal of technology as univalently positive, while the majority have nuanced and ambivalent responses to the use of PNDTs. Further, the interface of authoritative knowledge and the technological imperative suggests that AK derives not only from medical provider status and technology use, but also from the adequacy and trustworthiness of the information. The issue of timing and uncertainty of the information also are interrogated for their impact on women's lives and what that can illuminate about the theories of AK and the technological imperative.

    2016-03-01

    Full Text Available Based on the understanding of identity as an individual’s identity with the self within the cultural historical chronotope, and experienced as the feeling of belonging/ non-belonging to some communities, controllability/uncontrollability of situations and predictability/non-predictability of events, the paper describes the processes of identity transformation in the course of a technological development. Taken as the initial point, the idea of organ-extension (K. Marx, E. Kapp and technological extension of man (S. Freud, M. McLuhan means that technologies are the extension of a human body and its organs. The processes of technological extension assume a particular scale under condition of information society development, within which computer-, telecommunication-, transport-, bio-, nano- and other high technologies have become an actual cultural historical force that has a power to transform a human. Special attention is paid to the fact that unlike the precedent technologies that have just facilitated some or other human performance, modern technologies of information society do not only change the human topology, widen and expand human natural abilities but also really transform higher mental functions and mediate mental processes and relations between human individuals. Man becomes not only a biological and social creature but also a technological one, i.e. so called HOMO TECHNOLOGICUS. The scale and speed of cultural historical changes make the study of the technological extensions role in the transformation of identity a key point for developing ways of comprehending their role in the life of a modern person, and also for forecasting the evolution of relationship between man and machines in the future.

    2012-12-01

    The NASA Earth Science Technology Office (ESTO) regularly makes investments for nurturing advanced concepts in information technology to enable rapid, low-cost acquisition, processing and visualization of Earth science data in support of future NASA missions and climate change research. In 2012, the National Research Council published a mid-term assessment of the 2007 decadal survey for future spacemissions supporting Earth science and applications [1]. The report stated, "Earth sciences have advanced significantly because of existing observational capabilities and the fruit of past investments, along with advances in data and information systems, computer science, and enabling technologies." The report found that NASA had responded favorably and aggressively to the decadal survey and noted the role of the recent ESTO solicitation for information systems technologies that partnered with the NASA Applied Sciences Program to support the transition into operations. NASA's future missions are key stakeholders for the ESTO technology investments. Also driving these investments is the need for the Agency to properly address questions regarding the prediction, adaptation, and eventual mitigation of climate change. The Earth Science Division has championed interdisciplinary research, recognizing that the Earth must be studied as a complete system in order toaddress key science questions [2]. Information technology investments in the low-mid technology readiness level (TRL) range play a key role in meeting these challenges. ESTO's Advanced Information Systems Technology (AIST) program invests in higher risk / higher reward technologies that solve the most challenging problems of the information processing chain. This includes the space segment, where the information pipeline begins, to the end user, where knowledge is ultimatelyadvanced. The objectives of the program are to reduce the risk, cost, size, and development time of Earth Science space-based and ground

    Since James Carroll (1971) made a strong case for "participatory technology", scientists, engineers, policy-makers and the public at large have seen quite a number of different approaches to design and implement participatory processes in technology assessment and technology policy. As these participatory experiments and practices spread over the last two decades, one could easily get the impression that participation turned from a theoretical normative claim to a working practice that goes without saying. Looking beyond the well-known forerunners and considering the ambivalent experiences that have been made under different conditions in various places, however, the "if" and "how" of participation are still contested issues when questions of technology are on the agenda. Legitimation problems indicate that attempts to justify participation in a given case have not been entirely successful in the eyes of relevant groups among the sponsors, participants, organizers or observers. Legitimation problems of participatory processes in technology assessment and technology policy vary considerably, and they do so not only with the two domains and the ways of their interrelation or the specific features of the participatory processes. If we ask whether or not participation is seen as problematic in technology assessment and technology policy-making and in what sense it is being evaluated as problematic, then we find that the answer depends also on the approaches and criteria that have been used to legitimize or delegitimize the call for a specific design of participation.

    The electricity markets are being opened up to competition all round the world. To succeed in competition electricity sellers want new information technology tools to use in managing the sale of electricity. The network companies are aiming to step up utilization of their distribution capacity and to optimize power quality and the reliability of supply. Consumers need solutions with which they can manage their own power consumption and tendering sellers. The Nordic countries have been the first to deregulate their electricity markets. This head start in time is being made use of to generate a head start in technology. Tekes has initiated a technology programme for the years 1998 to 2002, named TESLA - Information Technology and Electric Power Systems, to promote the competitiveness of the Finnish electricity industry in changing conditions. The objective of the programme is to adapt information technology extensively to power distribution and thus develop the potential for Finland`s electricity industry to succeed on world markets. At the moment power distribution technology forms about one third of Finland`s energy technology exports. The programme is also aimed at developing new data transfer and data processing applications for companies in information technology clusters. For Finnish parties in the electricity markets the programme will produce ways and means of (1) improving management and use of distribution networks, (2) implementing competition in electricity sales, and (3) increasing the efficiency of electricity use

  11. Wasting the Future: The Technological Sublime, Communications Technologies, and E-waste

    Directory of Open Access Journals (Sweden)

    Sebine Label

    2012-08-01

    Full Text Available Literally speaking, e-waste is the future of communications. E-waste is the fastest growing waste stream in the world, much of it communications technologies from cell phones to laptops, televisions to peripherals. As a result of policies of planned obsolescence working computers, cell phones, and tablets are routinely trashed. One of the most powerful and enduring discourses associated with emerging technologies is the technological sublime, in which technology is seen as intellectually, emotionally, or spiritually transcendent. It comprises a contradictory impulse that elevates technology with an almost religious fervor, while simultaneously overlooking some of the consequences of industrialism, as well as ignoring the necessity of social, economic, and governmental infrastructures necessary to the implementation and development of new technologies. The idea that a new technology will not pollute or harm the environment is a persistent, though often quickly passed over, theme in the technological sublime, echoed in discourses about emerging technologies such as the silicon chip, the internet, and other ICTs. In this paper, I make connections between the discourse of newness, the practice of planned obsolescence, and the mountains of trashed components and devices globally. Considering the global context demonstrates the realities of the penetration of ICTs and their enduring pollution and negative implications for the health of humans and nonhumans, including plants, animals, waterways, soil, air and so on. I use the discourse of the technological sublime to open up and consider the future of communications, to argue that this discourse not only stays with us but also contains within it two important and related components, the promise of ecological harmony and a future orientation. I argue that these lingering elements keep us from considering the real future of communications – e-waste – and that, as communications scholars, we must also

  14. Stimulating R and D of industrial energy-efficient technology. Policy lessons--impulse technology

    International Nuclear Information System (INIS)

    Luiten, Esther; Blok, Kornelis

    2004-01-01

    Stimulating research and development (R and D) of innovative energy-efficient technologies for industry is an attractive option for reducing greenhouse gas emissions. Impulse technology, an innovative papermaking technology, is always included in studies assessing the long-term potential of industrial energy efficiency. Aim of this article is to analyse the R and D trajectory of impulse technology in order to explore how government can stimulate the development of industrial energy-efficient technology. The concept of 'momentum' is used to characterise the network of actors and to understand the effect of government R and D support in this particular case study. The network analysis convincingly shows that although marketed as an energy-efficient technology, other benefits were in fact driving forces. Researchers at various national pulp and paper research institutes were successful in attracting government R and D support by claiming an improved energy efficiency. The momentum of the technology network was modest between 1980 and 1990. Therefore, government R and D support accelerated the development of impulse technology in this period. However, when the perspectives of the technology deteriorated--momentum decreased--researchers at national research institutes continued to attract government R and D support successfully. But 25 years of R and D--and over 15 years government R and D support--have not yet resulted in a proven technology. The case study illustrates the risk of continuing R and D support too long without taking into account actors' drivers to invest in R and D. Once momentum decreased, government should have been more circumspect in evaluating the (energy efficiency) promise of impulse technology. The major policy lesson is that government has to look beyond claimed energy efficiencies; government has to value (qualitative) information on (changing) technology networks in deciding upon starting, continuing or pulling out financial R and D support to

    Full Text Available Globalization, very complex phenomenon, involves overcoming the barriers between different states, which allowed the rapid transfer of capital, technology, information, and the "toxins" from one country to another. First, the technology formed the basis of rapid expansion of great ideas promoted by globalization. Undeniable progress in the field of technology and science, has conferred to the man extraordinary powers that have been used most often to the detriment of his spiritual progress. We must not deny that science and technology have brought many benefits to human, and he could expand the knowledge horizon upon the world in which he lives, exploiting information acquired and share them with others. Science and technology must become for postmodern man ways of talk and communion between human and divinity, all to the praise of God and the perfection of the creature.

    2014-01-01

    Full Text Available Although they were considered the ideologists of Yugoslav identity before the First World War, the members of Young Bosnia were not united regarding this issue. This is illustrated by the attitudes of the two main ideologists of the movement Vladimir Gaćinović and Dimitrije Mitrinović. Contrary to Mitrinović, who was one of the most eager promoters of the idea of the unity of the South Slavs, Gaćinović was distrustful of this idea. He understood it as the 'pouring Croatian water in Serbian wine'. Both of them had a big number of followers in students' revolutionary organizations, and these Serb-Croat and Yugoslav organizations were responsible for the Assassination at Sarajevo.

    Technology empowerment” means that innovation is increasingly accessible to ordinary people of limited means. As powerful technologies become more affordable and accessible, and as people are increasingly connected around the world, ordinary people are empowered to participate in the process of innovation and share the fruits of collaborative innovation. This annotated briefing describes technology empowerment and focuses on how empowerment may create challenges to U.S. national security. U.S. defense research as a share of global innovation has dwindled in recent years. With technology empowerment, the role of U.S. defense research is likely to shrink even further while technology empowerment will continue to increase the speed of innovation. To avoid falling too far behind potential technology threats to U.S. national security, U.S. national security institutions will need to adopt many of the tools of technology empowerment.

    One of problems in health environment is organic liquid waste from many pollutant resources. Environmental friendly technology for degrading this waste is ozone which produced by plasma discharge technology, but its capability is limited. However, it is needed a new environmental friendly technology which has stronger capability. This new technology is so called advanced oxidation technology. Advanced oxidation technology is a hybrid of ozone, peroxide, UV light and photo catalyst. In this paper, it is introduced basic principle of hybrid of ozone and titania photo catalyst semiconductor. The capability of organic liquid degradation will be stronger because there is new radical which is produced by chemical reaction between electron-hole pair from photo catalyst titania and water or oxygen. This new radical then degrades this organic pollutant. This technology is used to degrade phenol. (author)
