Authors: Zhang Yixin , Fu Zhen , Jia Haichao , Huang Yiping , Li Xiaobei , Liu Hao , Li Weiran
Published: November 2018

Objectives:

This study evaluated the long-term stability of maxillary protraction (MP) in patients with complete unilateral cleft lip and palate (UCLP) and identified factors influencing relapse and long-term outcomes.

Materials and Methods:

Twenty-three adolescents with UCLP who underwent MP therapy were recalled when craniofacial growth was close to completion. Subjects exhibiting reverse/positive overjets were assigned to unstable/stable groups. Lateral cephalometric measurements were made before treatment (T0), after active treatment (T1), and at the end of the growth spurt (T2).

Results:

About 63% of the subjects exhibited positive overjets during follow-up. The unstable group demonstrated higher B–x and Co–Gn distances than the stable group (both P < .05) at T0. More short-term (T0–T1) sagittal advancement of point A (A–y) was evident in the unstable group than in the stable group (P < .05), but no long-term difference was apparent between the two groups (P = .481). During the posttreatment period (T1–T2), the SNA angle and maxillary incisor protrusion (U1–SN angle) were considerably lower in the unstable group than in the stable group (both P < .05). Overall, the unstable group exhibited a lower increase in the vertical extent of point A (A–x) than the stable group from T0 to T2 (P < .05).

Conclusions:

In the long term, MP affords favorable maxillary advancement in patients with UCLP. A mandibular excess at T0 and vertical maxillary hypoplasia may contribute to the long-term relapse of a reverse overjet.

Premenopausal women exhibit enhanced insulin sensitivity and reduced incidence of type 2 diabetes (T2D) compared with age-matched men, but this advantage disappears after menopause with disrupted glucose homeostasis, in part owing to a reduction in circulating 17β-estradiol (E2). Fasting hyperglycemia is a hallmark of T2D derived largely from dysregulation of hepatic glucose production (HGP), in which Foxo1 plays a central role in the regulation of gluconeogenesis. Here, we investigated the action of E2 on glucose homeostasis in male and ovariectomized (OVX) female control and liver-specific Foxo1 knockout (L-F1KO) mice and sought to understand the mechanism by which E2 regulates gluconeogenesis via an interaction with hepatic Foxo1. In both male and OVX female control mice, subcutaneous E2 implant improved insulin sensitivity and suppressed gluconeogenesis; however, these effects of E2 were abolished in L-F1KO mice of both sexes. In our use of mouse primary hepatocytes, E2 suppressed HGP and gluconeogenesis in hepatocytes from control mice but failed in hepatocytes from L-F1KO mice, suggesting that Foxo1 is required for E2 action on the suppression of gluconeogenesis. We further demonstrated that E2 suppresses hepatic gluconeogenesis through activation of estrogen receptor (ER)α–phosphoinositide 3-kinase–Akt–Foxo1 signaling, which can be independent of insulin receptor substrates 1 and 2 (Irs1 and Irs2), revealing an important mechanism for E2 in the regulation of glucose homeostasis. These results may help explain why premenopausal women have lower incidence of T2D than age-matched men and suggest that targeting ERα can be a potential approach to modulate glucose metabolism and prevent diabetes.

Published: November 2018

In the current work, it was investigated to the K X-ray fluorescence efficiency and chemical effect on vacancy transfer probability for some tin compounds. We used Br2Tin, TinI2, SeTin, TinF2, TinSO4, TinCl2, TinO and TinS compounds for experimental study. The target samples were irradiated with 241Am annular radioactive source at the intensity of 5 Ci which emits gamma rays at wavelength of 0.2028 nm. The characteristic x-rays emitted because of the excitation are collected by a high-resolution HPGe semiconductor detector. It has been determined that the experimental calculations of the tin (Sn) element are compatible with the theoretical calculation. In addition, we have calculated the experimental intensity ratios, fluorescence yields and total vacancy transfer probabilitiesfor other Sn compounds.
Effect of an Inverse Parabolic Confining Electric Potential on Third Harmonic Generation in Cylindrical Quantum Wires
Authors: Tshipa Moletlanyi
Published: November 2018

A theoretical investigation of the effect of an inverse parabolic potential on third harmonic generation in cylindrical quantum wires is presented. The wave functions are obtained as solutions to Schrödinger equation solved within the effective mass approximation. It turns out that peaks of the third harmonic generation susceptibility (THGS) associated with nanowires of small radii occur at larger photon energies as compared to those associated with quantum wires of larger radii. The inverse parabolic potential red-shifts peaks of the THGS, and suppresses the amplitude of the THGS. THGS associated with higher radial quantum numbers is diminished in magnitude and blue-shifted, as a function of the photon energy. As a function of the inverse parabolic potential, the THGS still characterized by peaks, and the peaks shift to lower values of the potential as the photon energy increases.

Current status of plant parasitic nematodes and their management of major spice crops
Authors: Pervez Rashid
Published: November 2018

Major spices crops such as black pepper (Piper nigrum L.), cardamom (Elettaria cardamomum Maton.) and turmeric (Curcuma longa L.) production in India is sustained losses due to several reasons. Among them, one of the major constraints are nematode infesting diseases, which causes significant yield losses and affecting their productivity. The major nematode pests infesting these crops include burrowing nematode Radopholus similis; root knot nematode, Meloidogyne incognita and M. javanica on black pepper. Whereas, lesion nematode, Pratylenchus sp., M. incognita and R. similis infesting cardamom and turmeric crops. Black pepper is susceptible to a number of diseases of which slow decline caused by R. similis and M. incognita or Phytophthora capsici  either alone and in combination and root knot disease caused by Meloidogyne spp. are the major ones.  Root knot disease caused by Meloidogyne spp. is major constraints in the successful cultivation and production in cardamom. Turmeric is susceptible to a number of diseases such as brown rot disease is caused by Fusarium sp. and lesion nematode, Pratylenchus sp. and root knot disease caused by M. incognita. Adoption of integrated pest management schedules is important in these crops since excessive use of pesticides could lead to pesticide residues in the produce affecting human health and also causing other ecological hazards.
Immunogenic cell death: Chemoimmunotherapy in the clinic
Authors: Bulbul Ajaz
Published: November 2018

Although cancer chemotherapy has historically been considered immune suppressive, we now understand that combining chemoimmunotherapy incites a mechanism called Immunogenic cell death. These mechanisms are now moving from concepts to the clinic. Recently dramatic advances in lung cancer treatment by combining chemotherapy with immunotherapy have led the way to this new frontier in cancer medicine. We will explain the mechanism behind ICD and how it will perhaps breathe a new life into chemotherapy use in cancer, not front and center but as a helpful hand to immunotherapy.

Marcuse. Muerte, Memoria y Dominio
Authors: Escobar Moncada Jairo
Published: November 2018

En este ensayo quiero ocuparme de la manera como Marcuse piensa la muerte y el morir, una manera de pensar que considera a la muerte no solamente como un acontecimiento biológico, sino ante todo como un acontecimiento marcado profundamente por la política y social prevaleciente, que es algo que comparte con otros pensadores de la llevada Teoría Crítica. El caso es que muchos temen la muerte como el peor y más terrible mal. ¿Es posible pensarla de otra manera, sin dejar de verla como el hecho biológico que es, pero sin caer en la tentación de pensarla como algo religiosa o metafísicamente sancionado, algo que pueda ser asumido sin temor ni pavor, sin angustia y sin autoengaños políticos o sociales?
The Use of Entanglement Entropy to Classify Quantum Phase Transitions in 1D Ultracold Spinor Bosons
Authors: Rodríguez Ramírez Karen
Published: November 2018

In this paper, we discuss a novel method based on a quantum-information-toolsuitable to identify and characterize quantum-phases and phase transitions in a broad set of lattice models relevant in condensed-matter systems. The method relies on theentanglement entropy which, for instance, can be calculated using the Matrix ProductState (MPS) algorithm, or any other method, for several system sizes to perform an appropriate scaling. Particularly, this advanced method has been applied for a ﬁnite 1D system of repulsively interacting spin-1 bosons and obtaining the universality class via the calculation of the central charge for the extemal ﬁeld-induced phase transitionbetween the dimerized phase and the XY-nematic phase in the antiferromagnetic regime.Finally, we brieﬂy discuss how this method has been recently used to identify topologicalphases.

Published: November 2018

Los altos costos que implica el consumo de cocaína pura, llevó a la producción de base de cocaína o bazuco (crack), un producto de menor valor económico, gran demanda y generalmente más usado por consumidores de bajo nivel socioeconómico. El bazuco es una sustancia blanca, o pardusca, semisólida o sólida, cuyo principio activo es la cocaína. La cocaína es un alcaloide con una larga historia de uso y abuso. Su determinación, tanto en muestras no biológicas como en fluidos biológicos continúa siendo una tarea de primer orden. En el presente trabajo se reporta la validación de un método de extracción de la cocaína en muestras de orina, usando la técnica de extracción en fase sólida (SPE). Porcentajes de recuperación entre el 99.4 y el 99.8% fueron obtenidos para cocaína empleando SPE. La técnica cromatográfica fue estandarizada, empleando una columna C18, un detector ultravioleta (254 nm), una fase móvil de agua-acetonitrilo-ácido acético (58-40-2) a un flujo de 0.4 mL/min. El rango de linealidad estuvo entre 0.01 µg/mL y 1.0 µg/mL. Se crearon tres curvas de cuantificación: 10 – 20 ppb, 20 – 100 ppb y 100 – 1000 ppb con coeficientes de determinación r 2  de 0.9965, 0.9947 y 0.9973 respectivamente. El método fue aplicado en muestras de orina de un grupo de personas voluntarias que consumen bazuco en la ciudad de Popayán, Cauca, Colombia.

Authors: Reyes-Solís Lina M. , Restrepo Jaime , Sánchez Rubén A.
Published: November 2018

La piperina, alcaloide presente en la especie vegetal pipilongo (Piper tuberculatum) a la cual se le asocian propiedades antioxidantes, fue encapsulada en vesículas multilamelares (MLV). Para ello se realizó la validación de la metodología de extracción a través de curvas de calibración de piperina estándar por cromatografía líquida de alta resolución (HPLC) utilizando una columna C18, fase móvil MetOH:H2O (70:30) y detectada por UV a 340 nm con una tasa de flujo de 0.7 mL/min. El rango lineal y linealidad fueron halladas entre 1 a 300 ppm, con R2 de 0.995. En la extracción del fruto de pipilongo se estudió el efecto de dos factores, disolventes y potencia de ultrasonido, para la optimización de condiciones y mayor extracción de piperina en pipilongo. La máxima concentración de piperina (246.50 ppm) fue encontrada en las condiciones de ultrasonido (US 20 KHz a 175W, 40 min) utilizando etanol como disolvente de extracción. Del extracto, se aisló la piperina utilizando una solución de KOH 10% etanólico. Fue purificada y caracterizada mediante punto de fusión, IR, GC-MS y RMN 1H. Una vez obtenido el extracto, se procedió a la formación de liposomas. Las vesículas de fosfatidilcolina y colesterol fueron preparadas con extracto y con piperina a diferentes concentraciones e hidratadas con buffer PBS a pH 7.40. El tamaño promedio de las partículas formadas, medido por dispersión de luz dinámica (DLS), estuvo en un rango de 299.7–531.9 nm. Para el estudio de la actividad antioxidante, se preparó una solución de DPPH 0.2 mM y se llevó a reacción con los liposomas de extracto y de piperina y sus correspondientes formas libres durante 60 min, medidos a 520 nm. El IC50 calculado para el extracto y la piperina fueron 2.8±0.2 y 21333±1499 ppm, respectivamente. Estos valores de IC50 fueron comparados frente a un estándar de referencia preparado bajo las mismas condiciones, quercetina (IC50 2.5±0.1 ppm). El ensayo con DPPH mostró que la forma liberada posee mayor actividad antioxidante mientras que en la encapsulación atenúa y estabiliza esta capacidad.

How to Sustain the Empire without Military Presence
Authors: Mashego Goodenough
Published: November 2018

The common factor in the global colonial project by European countries has been the introduction of their language and culture to â€œvanquishedâ€ communities. This is visible in the African continent and Latin America. As they intended to create a â€œhome away from home,â€ even after former British Prime Minister Harold MacMillanâ€™s â€œwinds of changeâ€ have breezed through, collapsing one empire after another, the mainstay feature of those coloniesâ€”languageâ€”remains at the heart of liberated nations. This often unavoidable status quo has meant that the colonial project cannot be completely dismantled without leaving remnants of it that will forever connect the colonised with their former coloniser. Language has been used through centuries as a potent weapon against native communities who have never fully developed dictionaries and other forms of language preservatives. The apartheid society, as a colonial project, went a step further by cleansing some languages and Balkanising them with others, thus creating artificial linguistic communities for reasons of ethnic governance. In its manifestation this process was supposed to produce a gradual death of â€œotherâ€ languages in a covert ethnic genocide that pitched ethnic communities against each other. Why has South Africa, 24 years later, not reversed this apartheid hurdle that gave birth to Bantustans and homelands? Why did the democratic government agree on a figure of 11 official languages when they knew from their own membership both inside and outside the country that there were more than nine African languages spoken in South Africa? What can be done to assist authorities to get a proper grasp of the linguistic challenges facing the country at a time that some people feel culturally conquered without a shot having been fired? And why is a democratic dispensation continuing the conquest of ethnic minorities?

Published: November 2018

Energy optimization is of vital importance especially in oil, gas and petrochemical industries. Distillation column with high energy consumption is one of the most common equipment in the aforementioned industries. Thus, it is important to revise the projection of initial process, reduce energy consumption and recover some of used energy. In this work, we studied energy optimization of a naphtha treating unit in a petrochemical company using Aspen HYSYS software. For energy optimization, feed temperature was changed to a satisfactory temperature (47 °C) for condensation of overhead steam distillation. Feed was used as a cooling fluid in the heat exchanger before the main condenser. According to outcome, 644.11 MW of energy was recovered and approximately 53% less energy was used in the air conditioner. Feed was injected in tower with higher temperature (212 °C) because of preheating. This reduces consumed energy up to approximately 63% by reducing the entering flow rate of reboiler.

Modifikasi Osilasi Rabi Pada Nanoparticle Heterodimer: Pengaruh Jarak antar Partikel dan Intensitas Medan Iluminasi
Authors: Nugroho Bintoro Siswo , Arman Yudha
Published: November 2018

Telah dilakukan studi teoretis untuk mempelajari osilasi Rabi pada heterodimer yang terdiri dari semiconductor quantum dot (SQD) dan metal nanoparticle (MNP). SQD dimodelkan sebagai two-level system dan ditinjau dengan formalisme density matrix sedangkan MNP dimodelkan secara klasik dan dikarakterisasi dengan nilai polarisabilitasnya. Respon optik diamati untuk sistem yang diiluminasi dengan medan osilatif yang terpolarisasi linear pada arah paralel sumbu penghubung SQD-MNP. Persamaan gerak density matrix sistem diselesaikan secara numerik menggunakan Runge-Kuta-Fehlberg (RKF 45).  Hasil yang diperoleh menunjukkan bahwa hibridisasi SQD-MNP dapat menimbulkan interaksi yang menyebabkan terjadinya pergeseran frekuensi transisi resonansi dan perubahan laju dephasing pada sistem. Efek kopling tersebut terlihat dominan dan menjadi faktor utama dalam modifikasi osilasi Rabi ketika sistem dieksitasi dengan laser berintensitas rendah, I = 1 W/cm^2. Hibridisasi juga menyebabkan timbulnya medan induksi dari MNP yang berperan pada modifikasi osilasi Rabi saat sistem dieksitasi dengan laser berintensitas lebih tinggi, I = 10 W/cm^2. Efek modifikasi yang diamati dapat dikontrol dengan mengubah jarak pisah SQD-MNP.

Published: November 2018

A concise and selective synthesis of the dichlorinated meroterpenoid azamerone is described. The paucity of tactics for the synthesis of chiral organochlorides motivated the development of unique strategies for accessing these motifs in enantioenriched forms. The route features a novel enantioselective chloroetherification reaction, a Pd-catalyzed cross-coupling between a quinone diazide and a boronic hemiester, and a late-stage tetrazine [4+2]-cycloaddition/oxidation cascade.

Authors: Simões Patrícia Maria Uchôa , Barroca Karla Cabral
Published: November 2018

As concepções de infância enquanto categoria geracional e de criança enquanto construção social implicam em uma nova compreensão sobre a educação das crianças pequenas. Decorrente dessa concepção de infância, afirma-se uma perspectiva de desenvolvimento humano não linear, que não está dividido em etapas fragmentadas e não compreende a criança de hoje como o adulto do amanhã. O presente estudo analisou concepções de infância e de desenvolvimento infantil de familiares de alunos e profissionais de Educação Infantil. Os procedimentos de análise utilizaram quatro grupos focais em duas instituições de Educação Infantil, sendo dois compostos por familiares de alunos e dois por profissionais. Os registros foram transcritos e organizados nas temáticas propostas pelo estudo: criança e desenvolvimento infantil. Para cada temática, foram construídas categorias de análise. De forma geral, a análise das falas dos participantes revela uma visão positiva da Educação Infantil que é referida como território de possibilidades de construções sociais e desenvolvimento integral das crianças. Por fim, o estudo também aponta a necessidade do reconhecimento profissional no âmbito da creche e da pré-escola e na configuração das leis e da conduta governamental.
Breaking the link between disability and child and whanau poverty
Authors: Murray Sam
Published: November 2018

In New Zealand, disabled children are more likely to live in a oneparent household than are non-disabled children. The primary carers of disabled children have a higher unemployment rate than oneparent households in general. As a result, households with disabled children are significantly more likely to experience income poverty. This is not the case in the United Kingdom, where households with disabled children tend not to be at greater risk of income poverty. A key factor in preventing a greater risk of income poverty is the higher disability-related allowances in the United Kingdom: the median payment rate is almost three times higher than the New Zealand equivalents. There is a clear case for increasing the payment rate of the New Zealand disability-related allowances. There is also a clear case for an overhaul of support for households with disabled children to better enable carers/parents to work and to provide more equitable and effective support.

One of the contradictions of enclosures is that they both promoted and threatened property rights. The reforms aimed at establishing modern, uncontested land ownership also undermined existing property rights. In many countries reform legislation required unanimity or a qualified majority of landowners in order for it to be implemented. However, in Sweden, a single landowner was enough to start an enclosure. This study takes developments in a plain region of Western Sweden as emblematic of the economic and institutional mechanisms of enclosures. The first villages in the area were enclosed in 1805, the last in 1865. The fact that the two systems coexisted for six decades in this area provides a “historic laboratory” for the reconstruction of technological, productive and land value changes. One important research question relates to the slow advance of enclosures: how could open fields have survived for so long when every landowner could veto their very existence? Results show that up until the early 1850s, enclosed land offered few advantages for local farmers. This system was not more productive than open fields, nor did the reform stimulate the adoption of innovations such as convertible husbandry or iron ploughs. Still, in the long run, strong legal imperatives made enclosures almost inevitable. Consequently, the long period of parallel existence can be understood as the outcome of a situation in which the open fields still possessed an economic advantage, while enclosures enjoyed an institutional advantage.
How was the fertility transition carried out? Analysis of fertility control strategies and their evolution in rural Aragon, Spain (1880-1955)
Authors: Marco Gracia Francisco J. ,   Stellenbosch University

The aim of this article is to analyse the fertility control strategies employed by families during the fertility transition and to understand their evolution over time. To achieve that goal, this study identified the use and popularization of stopping and spacing. This analysis employed data on the inhabitants of 10 rural villages in the Huerva River valley in north-eastern Spain. The results revealed that in the first stages of the fertility transition, the same fertility control strategies used in the pre-transitional period were employed. However, stopping quickly became the most common strategy. Although women exercised some type of control over fertility at some point in their lives from the beginning of the fertility transition, it was not until the late 1920s that women who were controlling outnumbered those who were not (on 1 July of each year).
Archival Investigatory Record of the Chief of the Political Directorate for the Central Asian Military District, Brigade Commissar N. P. Katerukhin as a Source for Studying the Phenomenon of Mass Political Repression of the Red Army Commanders in 1937-1938

The article studies mass political repression in the USSR in 1937-1940s to offer an unbiased reconstruction of the process and to retrieve the historical experience at current stage of democratic transformations in the country. The article is devoted to one of the repressed Red Army command officers, head of the Political Directorate for the Central Asian Military District, Brigadier N. P. Katerukhin, participant in the First World and Civil Wars. It follows the fate of Katerukhin, who was awarded a rank of ‘Brigade Commissar’ in April 1938. The article focuses on the events of the second half of 1930s in the Central Asian Military District: mechanics of the NKVD investigation, operations and activities of commanders, political agencies, and military justice. Despite his honorable service, energy, initiative, and diligence at a difficult time of political strife, Katerukhin was under suspicion of the relevant authorities. Information on ‘sabotage activities’ of the secretary of the district party commission N. P. Katerukhin kept coming from ex-director of the military pedagogical faculty of the N. G. Tolmachev Military Political Academy M. G. Fradlin to the supreme bodies of the party since January 1937. The authors have studied N. P. Katerukhin’s archival investigatory record to show the nature of the NKVD activities at the time of contraction of mass political repression. The most important evidence against N. P. Katerukhin was ‘confessions’ of Division Commissar V. K. Kontstantinov, who in 1936 promoted Katerukhin’s assignment to the post of director of the district party commission. Kontstantinov admitted under questioning to participation in a counter-revolutionary organization and revealed that he enlisted Katerukhin to the said anti-Soviet organization. By then the investigators had testimonies that at the time of political purges N. P. Katerukhin had expelled blameless members and reinstated enemy elements. The materials of the archival investigatory record are being introduced into scientific use for the first time. Of particular value are the interrogation reports, which contain valuable materials on the military and political history of our country. All this bespeaks the importance of studying archival investigatory files as a source on history of mass political repression in the Red Army.
Synergetic Theory of Document in Evolution of Document Science
Authors:   Kazan State Power Engineering University, Kazan, Russian Federation, Dvoenosova Galina A.
Published: November 2018

The article assesses synergetic theory of document as a new development in document science. In information society the social role of document grows, as information involves all members of society in the process of documentation. The transformation of document under the influence of modern information technologies increases its interest to representatives of different sciences. Interdisciplinary nature of document as an object of research leads to an ambiguous interpretation of its nature and social role. The article expresses and contends the author's views on this issue. In her opinion, social role of document is incidental to its being a main social tool regulating the life of civilized society. Thus, the study aims to create a scientific theory of document, explaining its nature and social role as a tool of social (goal-oriented) action and social self-organization. Substantiation of this idea is based on application of synergetics (i.e., universal theory of self-organization) to scientific study of document. In the synergetic paradigm, social and historical development is seen as the change of phases of chaos and order, and document is considered a main tool that regulates social relations. Unlike other theories of document, synergetic theory studies document not as a carrier and means of information transfer, but as a unique social phenomenon and universal social tool. For the first time, the study of document steps out of traditional frameworks of office, archive, and library. The document is placed on the scales with society as a global social system with its functional subsystems of politics, economy, culture, and personality. For the first time, the methods of social sciences and modern sociological theories are applied to scientific study of document. This methodology provided a basis for theoretical vindication of nature and social role of document as a tool of social (goal-oriented) action and social self-organization. The study frames a synergetic theory of document with methodological foundations and basic concepts, synergetic model of document, laws of development and effectiveness of document in the social continuum. At the present stage of development of science, it can be considered the highest form of theoretical knowledge of document and its scientific explanatory theory.
Features of Development of the Black Sea Village in 1920s: Materials from the Black Sea Party Obkom Fond in the Documentation Center for Contemporary History of the Krasnodar Krai

The article studies features of socio-economic and socio-political development of the Black Sea village in 1920s. Documents from the fond of the Black Sea District Committee (Obkom) of the RCP (b) -VKP (b) stored in the Center for Documentation of the Modern History of the Krasnodar Krai allow not only to reconstruct the developments in the Black Sea village in the NEP days, but also to understand the nature of its evolution. Uniqueness of the Black Sea village was greatly determined by its geographical environment. There had formed a sectoral makeup of agricultural production: fruit-farming, viticulture, tobacco growing. Rugged relief forced peasants to form holdings or farms; therefore rural communities were rare. Its another distinctive feature was its motley national composition. Over 50 ethnic groups inhabited the district, among most numerous were the Russians, the Ukrainians, the Armenians, and the Greeks. In the first years of the NEP, the main tasks facing district authorities were to develop ‘high-intensity’ industries and to shape local peasant farms into food base for cities and resorts. While tackling these tasks, they had to deal with shortages of land and poor communications and to bring lease relations and work-hands employment up to scratch. The situation was complicated by socio-political inertia of rural population of the district that came from the absence of community tradition. Study of the documents from the fond of the Black Sea party obkom shows that local authorities were well aware of the peculiarity of their region, but in most cases had to follow guidelines set ‘from above’ to introduce all-Russian standards.
Attempt upon the Life of P. N. Milyukov and Assassination of V. D. Nabokov in Berlin (1922): Testimony of the Accused Monarchist S.V. Taboritzky

This publication introduces into scientific use and analyses a document on the planning and realization of the assasination attempt on P.N. Milyukov and the murder of V.D. Nabokov on March 28, 1922. The criminals, far-right Russian monarchists P.N. Shabelsky-Bork and S.V. Taboritzky were arrested on the crime scene (the Berlin Philarmonic Hall, where P.N. Milyukov had a public lecture). On the next day, on March 29, 1922, they gave testimonies to the Berlin criminal police. The published document is the testimony of S.V. Taboritsky, who was accused of murder of V.D. Nabokov, one of the leaders of the Constitutional Democratic Party, which was in opposition to the right monarchists. Nabokov wasn't the target of this act of terrorism; his murder wasn't planed, it was unintentional. Trying to prove Taboritzky's innocence, Shabelsky and Taboritzky tried to justify their actions and kept changing their testimonies during the inquiry and trial. Taboritzky wasn’t to shoot Mliyukov or any others Kadets. He came, primarily, to give his moral support to Shabelsky. V.D. Nabokov was killed in struggle, when turmoil and panic spread. Thus, the most important questions facing the investigation was whether it was S. Taboritzky who shot Mliyukov and whether he had any weapon on himself that day. However, numerous witnesses confirmed Taboritzky's guilt. The published testimonies contain evidence unfavourable to Taboritzky and also some accurate data on the attempt preparation. Relying on information from the witnesses and these testimonies of Taboritzky (and disregarding his later testimonies) the court convicted him. He shot V. Nabokov, when he seized P.N. Shabelsky who attempted to kill Milyukov. His behavior during the investigation and trial caused much irritation in the Berlin penal court, and Taboritzky was sentenced to 14-years imprisonment. On other questions reviewed in court (motives of crime, accomplices, role P.N. Shabelsky, events of evening on March 28, 1922) S. Taboritzky repeated the earlier testimonies of Shabelsky.
