A quantitative study of the pathological changes in the cerebellum in 15 cases of variant Creutzfeldt–Jakob disease (vCJD)

Aims: To determine in the cerebellum in variant Creutzfeldt–Jakob disease (vCJD): (i) whether the pathology affected all laminae; (ii) the spatial topography of the pathology along the folia; (iii) spatial correlations between the pathological changes; and (iv) whether the pathology was similar to that of the common methionine/methionine Type 1 subtype of sporadic CJD. Methods: Sequential cerebellar sections of 15 cases of vCJD were stained with haematoxylin and eosin, or immunolabelled with monoclonal antibody 12F10 against prion protein (PrP) and studied using spatial pattern analysis. Results: Loss of Purkinje cells was evident compared with control cases. Densities of the vacuolation and the protease-resistant form of prion protein (PrPSc) (diffuse and florid plaques) were greater in the granule cell layer (GL) than the molecular layer (ML). In the ML, vacuoles and PrPSc plaques occurred in clusters regularly distributed along the folia with larger clusters of vacuoles and diffuse plaques in the GL. There was a negative spatial correlation between the vacuoles and the surviving Purkinje cells in the ML. There was a positive spatial correlation between the vacuoles and diffuse PrPSc plaques in the ML and GL. Conclusions: (i) all laminae were affected by the pathology, the GL more severely than the ML; (ii) the pathology was topographically distributed along the folia especially in the Purkinje cell layer and ML; (iii) pathological spread may occur in relation to the loop of anatomical connections involving the cerebellum, thalamus, cerebral cortex and pons; and (iv) there were pathological differences compared with methionine/methionine Type 1 sporadic CJD.

3D Reconstruction of the complex dielectric function of glass during femtosecond laser micro-fabrication

We report on a new technique to reconstruct the 3D dielectric function change in transparent dielectric materials and the application of the technique for on-line monitoring of refractive index modification in BK7 glass during direct femtosecond laser microfabrication. The complex optical field scattered from the modified region is measured using two-beam, single-shot interferogram and the distribution of the modified refractive index is reconstructed by numerically solving the inverse scattering problem in Born approximation. The optical configuration suggested is further development of digital holographic microscopy (DHM). It takes advantage of high spatial resolution and almost the same optical paths for both interfering beams, and allows ultrafast time resolution.

Novel sol–gel preparation of (P2O5)0.4–(CaO)0.25–(Na2O)X–(TiO2)(0.35−X) bioresorbable glasses (X = 0.05, 0.1, and 0.15)

Quaternary phosphate-based glasses in the P2O5–CaO–Na2O–TiO2 system with a fixed P2O5 and CaO content of 40 and 25 mol% respectively have been successfully synthesised via sol–gel method and bulk, transparent samples were obtained. The structure, elemental proportion, and thermal properties of stabilised sol–gel glasses have been characterised using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), 31P nuclear magnetic resonance (31P NMR), titanium K-edge X-ray absorption near-edge structure (XANES), fourier transform infrared (FTIR) spectroscopy, and differential thermal analysis (DTA). The XRD results confirmed the amorphous nature for all stabilized sol–gel derived glasses. The EDX result shows the relatively low loss of phosphorus during the sol–gel process and Ti K-edge XANES confirmed titanium in the glass structure is in mainly six-fold coordination environment. The 31P NMR and FTIR results revealed that the glass structure consist of mainly Q1 and Q2 phosphate units and the Ti4+ cation was acting as a cross-linking between phosphate units. In addition DTA results confirmed a decrease in the glass transition and crystallisation temperature with increasing Na2O content. Ion release studies also demonstrated a decrease in degradation rates with increasing TiO2 content therefore supporting the use of these glasses for biomedical applications that require a degree of control over glass degradation. These sol–gel glasses also offer the potential to incorporate proactive molecules for drug delivery application due to the low synthesis temperature employed.

Eastern Christianity and politics in the Twenty-First Century

This book provides an up-to-date, comprehensive overview of Eastern Christian churches in Europe, the Middle East, America, Africa, Asia and Australia. Written by leading international scholars in the field, it examines both Orthodox and Oriental churches from the end of the Cold War up to the present day. The book offers a unique insight into the myriad church-state relations in Eastern Christianity and tackles contemporary concerns, opportunities and challenges, such as religious revival after the fall of communism; churches and democracy; relations between Orthodox, Catholic and Greek Catholic churches; religious education and monastic life; the size and structure of congregations; and the impact of migration, secularisation and globalisation on Eastern Christianity in the twenty-first century.

The Romanian Orthodox Church

At first glance, the nationalist ideology of the French Revolution seems to have had little impact on the Orthodox Church in Romanian-speaking territories. Romanians were the predominant inhabitants of the principalities of Wallachia and Moldavia and the neighboring territories of Transylvania (including Crişana, Maramureş and Banat), Bukovina, Bessarabia, and Dobrudja. The majority of ethnic Romanians belonged to the Orthodox faith while their communities were at the intersection of geopo liti cal interests of the Rus sian, Ottoman, and Habsburg empires. In 1859 the Principalities of Wallachia and Moldavia (known as the Old Kingdom between 1866 and 1918) united into a single state under the rule of a local prince. The term "Romania" began to be used by the new state in its of cial documents in 1862. Two years later, the state supported the declaration of a Romanian autocephalous (in de pen dent) church that was recognized by the Ecumenical Patriarchate in 1885. As an integrative part of the Orthodox commonwealth, the church was situated between the competing jurisdictions of the Ecumenical Patriarchate and the Rus sian Orthodox Church, while its declaration of autocephaly followed a pattern in the spread of national churches in Southeastern Europe. From the Treaty of Kuchuk Kainardji of 1774 to the beginning of the Greek War for In de pen dence in 1821, the Romanian principalities were under the suzerainty of the Ottoman Empire, which had full control of their po liti cal and economic affairs. The sultan appointed princes, and the Porte determined their po liti cal and judicial status. The princes were drawn from the "Phanariots," and were directly appointed by the Porte from preponderantly Greek elite rather than the Romanian local elite, the boyars (boieri).1 In each principality, the church was headed by a metropolitan who was under the direct jurisdiction of the Ecumenical Patriarchate. That religion mattered to local population as a means of social cohesion was suggestively depicted by Anatole de Demidoff, an En glish traveler in the region in 1837. Arriving in Bucharest, the capital of Wallachia, he claimed that: I know of no city in Europe in which it is possible to find more agreeable society, or in which there is a better tone, united with the most charming gaiety⋯. Religion, which is here of the schismatic Greek creed, does not, properly speaking, hold any great empire over the minds of the Wallachian people, but they observe its outward forms, and particularly the austerities of fasting, with scrupulous exactitude. The people are seen to attend divine ser vice with every sign of respect, and the great number of churches existing in Wallachia, bear witness to the ardent zeal with which outward worship is honored.2 The Romanian Orthodox Church was a national institution, closely linked to social, economic, and po liti cal structures. In most cases, Orthodox hierarchs were appointed from the families of boyars, thus ensuring a close relationship with the state authorities and its policies. As one of the largest landowners in the principalities, the church had a prime role in administrating healthcare and education. Although the majority of the clergy was uneducated, it dispensed both ecclesiastical and civil justice and in many cases worked closely with boyars in local administration.3 The lower clergy not only contributed directly to the economy but also benefited from tax privileges. Some small villages had an unusually high proportion of clergy in comparison to the overall population. For example, in 1810, Stənisləveşti, a village in the south of Wallachia, was composed of eleven houses and had two priests, five deacons, and three cantors; similarly, the Frəsinet village of nineteen houses had two priests and five deacons.4 Although these cases were exceptional, they indicate both the economic value of being a member of the clergy and the wider canonical dimension of church jurisdiction. The special status of the clergy was reflected not only at lower but also at higher levels. Bishops and metropolitans engaged with state policy and in many cases opposition to the authorities led to the loss of a spiritual seat. The metropolitan of each principality worked with the prince and was president of the divan, the gathering of all boyars. He held the right to be the first person to comment on state policy and to make recommendations when the prince was absent. The metropolitan replaced the prince when the principality had no political ruler, such as in the cases of Metropolitan Veniamin Costachi of Moldavia in 1806 and Metropolitan Dositei Filitti of Wallachia, while the bishops of Buzəu and Argeş were members of the provisional government during the Rus sian occupation of the principalities in 1808. The higher clergy had both religious and political prerogatives in relation to foreign powers as evident in their heading of the boyars' delegation to peace negotiation between the Rus sian and Ottoman empires at Focşani in 1772 and addressing memoranda to the Austrian and Rus sian governments in 1802.5 The primary role of the church in the principalities of Moldavia and Wallachia was paralleled by the national mobilization of Orthodox communities in the neighboring territories that had Romanian inhabitants. Although throughout the region Orthodox communities were incorporated into church structures as part of the Habsburg, Austrian or Rus sian empires, the nineteenth century was characterized by the leadership's search for political autonomy and the building of a Romanian national identity. The Orthodox communities outside the Old Kingdom maintained relations with the faithful in principalities across the Carpathian Mountains and the Dniester River and sought support in their struggle for political and religious rights.

Recovery of glass fibre and carbon fibres from reinforced thermosets by batch pyrolysis and investigation of fibre re-using as reinforcement in LDPE matrix

A semi-batch pyrolysis process was used to recover samples carbon fibre and glass fibre from their respective wastes. The mechanical properties of the recovered fibres were tested and compared to those of virgin fibres, showing good retention of the fibre properties. The recovered fibres were then used to prepare new LDPE composite materials with commercial and laboratory-synthesized compatibilizers. Mild oxidation of the post-pyrolysis recovered fibres and the use of different compatibilizers gave significant improvements in the mechanical properties of the LDPE composites; however some of the manufactured composites made from recovered fibres had properties similar to those made from virgin fibres.

A munkával kapcsolatos értékek és attitűdök változása Közép-Kelet Európában a XXI. század első évtizedében (Changing values and attitudes regarding labour in Central- Eastern Europe in the first decade of 21st century)

A szerző tanulmányában a 2000 és 2010 közötti gazdasági és társadalmi változásokat és a munkával kapcsolatos értékek és attitűdök alakulását állítja időbeli párhuzamba, és azokra a kérdésekre keresi a választ, hogy milyen prioritások jellemzik 2010-ben a munka egyes aspektusaihoz való viszonyulást Közép-Kelet- Európa uniós tagállamaiban, és közöttük kiemelten Magyarországon? Vajon változtak-e ezek a jellemzők az elmúlt tíz év során, s ha igen, milyen irányú az elmozdulás. Azonos tendenciájúak-e a változások a vizsgált országokban? Megállapíthatók-e jellegzetes különbségek három kiválasztott, magas életszínvonalú, régebbi uniós (EU-15) tagországhoz viszonyítva? Elemzése jelentős mértékben támaszkodik az EVSfelmérés 2010-ben közzétett adataira, melynek alapját a 2008 és 2009 során lefolytatott adatgyűjtés képezi. Tanulmányában azokra a közép-kelet-európai országokra összpontosít, amelyek az elmúlt évtized során az unió tagjai lettek, és a 2000-es felmérésben is részt vettek már. _____ The author sets into parallelism economic and social changes and the development of values and attitudes regarding labour between 2000 and 2010, and looks for answers to questions what priorities characterize in 2010 the attitude to some aspects of labour in EU member countries of CEE, and especially in Hungary. Have these features changed in the last decade and in positive case, what is the direction of the shift? Are changes of similar tendency in countries under consideration? Can considerable differences be stated as compared to three selected, earlier EU 15 member countries with high living standard? The analysis largely relies on data of EVS survey, published in 2010 whose basis is the data collection carried out in 2008-2009. The essay focuses on Central Eastern European countries which have become members of the Union during the last decade and took part already in the survey of 2000.

Politics and prayer in West Perrine, Florida: Civic social capital and the black church

This thesis traces the mechanisms and sources responsible for the generation of civic social capital (a set of shared norms and values that promote cooperation between groups, enabling them to participate in the political process) by black churches in West Perrine, Florida. Data for this thesis includes over fifty interviews and participant observations, archival records, newspaper articles, and scholarly journals. ^ Despite the institutional racism of the first half of the twentieth century, many blacks and whites in Perrine developed levels of trust significant enough to form an integrated local governing body, evidence of high levels of csc. At mid-century, when black and white interactions ceased, Perrine's csc decreased, leading to the deterioration of Perrine's social and physical conditions. Perrine's csc increased in the 1980s by way of broad-based coalitions as Perrine's churches invested their csc in an effort to eradicate crime, clean up its neighborhood, and win back its youth. ^

Automatons, Robots, and Capitalism in a Very Wrong Twenty-First Century: A Review Essay on Neill Blomkamp’s Chappie

Contrary to prevailing opinions, Neill Blomkamp’s recent feature film Chappie is not a movie about robots or artificial intelligence. It is not Robocop. It is not Short Circuit. It is also not District 9 or Elysium. Chappie is a movie about humanity’s dialectically creative and destructive potential. It is a movie about how it is that humans come to behave how they do through their social and material circumstances, as well as the barbaric results when the two are mixed under the thoroughly undemocratic conditions of neoliberal capitalism.

Entre a cruz e a espada, a foice e o martelo: a representação do anticomunismo no Rio Grande do Norte

The objective of this dissertation is to investigate the propagation of an anticommunism movement in Rio Grande do Norte Estate, Brazil, in a process that started on the first decades of the twentieth century and shows reflections until today. Firstly, we introduce the operation promoted by the catholic oriented newspaper A Ordem. Through the analysis of publications from 1935 to 1945, we observe its role in an image campaign of the “Communist Conspiracy” event, in an attempt to legitimate the power of Right wing groups, specially the Catholic Church and the Military Police. The newspapers discourse is analyzed in serial, quantitative and qualitative perspectives. Secondly, we search to understand the space dynamic of the anticommunism discourse thought the creation of evocation and representation spaces that ended up becoming memory places. Our considerations are based on the concept of representation by Roger Chartier, observing the way communism is represented by A Ordem, as well as the spatial category used to reactivate the anticommunist memory and represent it. We analyze the interests that are served by the construction of the monuments, the Oral History, as well as the relation between the local communities with them. Thirdly, we establish a parallel with many authors, in an approach that gathers Cultural and Social elements and Political History, in order to find explanations for the articulation of these discourses.

Survival of a Perverse Nation: Sexuality and Kinship in Post-Soviet Armenia

Survival of a Perverse Nation traces the ways in which contemporary Armenian anxieties are congealing into the figure of the “homosexual.” As in other post-Soviet republics, homosexuality has increasingly become defined as the crisis of the times, and is understood by many as a destructive force linked to European encroachment. In Armenia, a growing right-wing nationalist movement since 2012 has been targeting LGBT and feminist activists. I suggest that this movement has arisen out of Armenia’s concerns regarding proper social and biological reproduction in the face of high rates of emigration of especially men in search of work. Many in the country blame this emigration on a post-Soviet oligarchy, with close ties to the government. This oligarchy, having quickly and massively privatized and liquidated industry and land during the war over the region of Nagorno-Karabagh (1990-1994) with Azerbaijan, created widespread un(der)employment. A national narrative attributing the nation’s survival of the 1915 Genocide and dispersion of its populations to strong morality preserved by institutions such as the Church and the family has now, in the post-Soviet era, ruptured into one of moral “perversion.” This dissertation is based on 15 months of ethnographic research, during which I participated in the work of two local non-governmental organizations: Public Information and Need for Knowledge, an LGBT rights organization and Women’s Resource Center, a feminist organization. I also conducted interviews with 150 households across Yerevan, the capital city, and did in-depth interviews with other activists, right-wing nationalists and journalists. Through psychoanalytic frameworks, as well as studies of kinship, I show how sovereignty – the longed for dream for Armenians over the last century – is felt to have failed because of the moral corruption of the illegitimate figures that fill Armenian seats of authority. I, thus, examine the ways in which a missing father of the household is discursively linked to the lack of strong leadership by a corrupt government, producing a prevalent feeling of moral disintegration that nationalists displace onto the “homosexual.”
