Analysis of the systems of ventilation of residential houses of Ukraine and Estonia
Authors: Savchenko Olena , Zhelykh Vasyl , Voll Hendrik 
Published: January 2018

Abstract
The most common ventilation system in residential buildings in Ukraine is natural ventilation. In recent years, due to increased tightness of structures, an increase in the content of synthetic finishing materials in them, the quality of microclimate parameters deteriorated. One of the measures to improve the parameters of indoor air in residential buildings is the use of mechanical inflow and exhaust ventilation system. In this article the regulatory documents concerning the design of ventilation systems in Ukraine and Estonia and the requirements for air exchange in residential buildings are considered. It is established that the existing normative documents in Ukraine are analogous to European norms, which allow design the system of ventilation of residential buildings according to European standards. However, the basis for the design of ventilation systems in Ukraine is the national standards, in which mechanical ventilation, unfortunately, is provided only for the design of high-rise buildings. To maintain acceptable microclimate parameters in residential buildings, it is advisable for designers to apply the requirements for designing ventilation systems in accordance with European standards.

Published: January 2018

Abstract
The influence of transit flow rate of water upon operative of the equipped with nozzles pressure pipeline is experimentally investigated. External pressure, which varies in the range of 1465-2295 mm, acted upon the pipeline. The angle β between vectors of velocities of the stream in the pipeline and jets which branch off through nozzles were given the value: 0° ; 45° ; 90° ; 135° ; 180°. The diameter of the pipeline was of D=20.18 mm, the diameter of nozzles d=6.01 mm. The distances between the nozzles were 180 mm, and the number of them 11. The value of the transit flow rate at input into the pipeline varied from 4.05 to 130.20 cm3 / s. The increase in flow rate of the transit flux Qtr
caused increase in non-uniformity of distribution of operating heads and increase in flow rate of water along the pipeline over the segment of its dispensation. On the segment of collecting of water, inverse tendency was observed. The number of nozzles through which water became to be dispensed increased with the increase in Qtr

Abstract
One of the promising directions of the use of expansive cements is making the protective bandages for the maintenance of pipelines. Bandages expansive application of the compositions of the pipeline reinforce the damaged area and reduce stress due to compressive stress in the cylindrical area. Such requirements are best suited for expansive compositions obtained from portland cement and modified quicklime. The article presents the results of expansive cements based on quick lime in order to implement protective bandages pipelines.
Pendeo-Epitaxy - A New Approach for Lateral Growth of Gallium Nitride Structures

A new process route for lateral growth of nearly defect free GaN structures via Pendeo-epitaxy is discussed. Lateral growth of GaN films suspended from {110} side walls of [0001] oriented GaN columns into and over adjacent etched wells has been achieved via MOVPE technique without the use of, or contact with, a supporting mask or substrate. Pendeo-epitaxy is proposed as the descriptive term for this growth technique. Selective growth was achieved using process parameters that promote lateral growth of the {110} planes of GaN and disallow nucleation of this phase on the exposed SiC substrate. Thus, the selectivity is provided by tailoring the shape of the underlying GaN layer itself consisting of a sequence of alternating trenches and columns, instead of selective growth through openings in SiO2 or SiNx mask, as in the conventional lateral epitaxial overgrowth (LEO).Two modes of initiation of the pendeo-epitaxial GaN growth via MOVPE were observed: Mode A - promoting the lateral growth of the {110} side facets into the wells faster than the vertical growth of the (0001) top facets; and Mode B - enabling the top (0001) faces to grow initially faster followed by the pendeo-epitaxial growth over the wells from the newly formed {110} side facets. Four-to-five order decrease in the dislocation density was observed via transmission electron microscopy (TEM) in the pendeo-epitaxial GaN relative to that in the GaN columns. TEM observations revealed that in pendeo-epitaxial GaN films the dislocations do not propagate laterally from the GaN columns when the structure grows laterally from the sidewalls into and over the trenches. Scanning electron microscopy (SEM) studies revealed that the coalesced regions are either defect-free or sometimes exhibit voids. Above these voids the PEGaN layer is usually defect free.

Ethnos e demos: a construção discursiva da identidade coletiva
Authors: Seriot Patrick 
Published: January 2018

O artigo trata da questão da construção de fronteiras identitárias, sociais e políticas em diferentes contextos históricos (França, Rússia), considerando fundamentalmente a noção de nação - relacionada à língua - e a construção discursiva dos nomes (do povo, da língua) dos elementos postos como fronteira. O autor considera que o estado atual dos problemas nacionais da Europa do Leste na ex-União Soviética pode ser parcialmente estudado, ou explicado, graças à história das definições conflitantes e incompatíveis de nação.
Jornalismo e a divulgação científica
Authors: Silva Telma Domingues da 
Published: January 2018

Neste artigo, procuro discutir a prática da divulgação científica realizada pela Mídia, por meio da análise das revistas SuperInterressante, da Editora Abril, e Galileu, da Editora Globo. Tais publicações teriam como objetivo colocar um conhecimento científico à disposição do grande público. A análise mostra como se dá essa prática da Mídia, em que se produz a imagem de um conhecimento científico apropriado para o grande público, leigo. Pode-se dizer que a prática jornalística resulta aí em um "aplainamento" sobre o fato científico, no que diz respeito à sua historicidade própria.
O corpo vivo da cidade: um lugar de memória
Authors: Brossaud Claire 
Published: January 2018

No decorrer dos anos 1960, o Direito à cidade de H. Lefehvre foi aplicado na concepção de uma cidade planejada franceses situada na alta Normandia. Isto favoreceu a visão de uma "cidade-corpo" trabalhada, no plano urban´stico, pela autodeterminação: era necessário das a cidade aos habitantes, como se se tratasse de tomar as rédeas do próprio destino. Trinta anos mais tarde, a memória oficial local passa a celebrar um indivíduo-ator no espaço público, no local e em lugar da cidade. Assiste-se à aparição de um "personalismo de ficção" cujos limites consistem, por um lado, em levar em consideração apenas um eterno presente individual e, por outro lado, em tornar invisíveis as razões que levaram este mesmo indivíduo a tornar-se ator de sua cidade-vida.

<p>Este artigo reflete sobre a imitação como uma possibilidade de aproximar a dança dos pequenos. Para tal, apresenta diálogos entre recortes de duas pesquisas que versam sobre a práxis educativa: a dissertação de mestrado (AUTOR, 2013) e o projeto de extensão Dançarelando. Ambas caracterizam-se por pesquisa-ações cujos dados foram coletados em diários de campos e confrontados com a teoria para identificação dos resultados. O estudo dessas propostas revelou que a imitação é adequada, principalmente se vinculada ao faz de conta; entretanto é necessário que não impeça a reelaboração das experiências. Desta forma, esse texto pretende contribuir com a formação de professores, por meio do compartilhamento de experiências práticas em dança, encontrando-se com as políticas públicas atuais. <strong></strong></p>
TEXT-STYLISTIC REPLICATION AS A BASIC CATEGORY OF MODERN ADVERTISING
Authors: Isaeva L. A. , Budanova S. G. , Ryabinina A. G. 
Published: January 2018

This article describes a special type of advertising texts characterized by a text-stylistic replication. This property of text implies an intentional imitation of the original source by preserving its typical distinctive feature that depends on the type of the first principle. This makes it possible to recognize the imitation despite the changing lexical, grammatical and subject-shaped components. The paper features a specific differentiation of such texts based on linguistic and / or rhythmic-sound imitation of the proto-word while taking into consideration the elements of the plot and expressive means. From the point of view of peculiarities of imitation of this or that source, construction and artistic organization in the advertising space, the following types of text-stylistic secondary nature can be distinguished: 1) the imitation of specific works; 2) the imitation of an indefinite number of similar works; 3) the imitation of speech of a particular speaker; 4) the imitation of an indefinite number of similar speeches. Within each of these types the advertising material is divided into additional groups, depending on the type of source and means of creating stylization. The paper provides a description of the basic features of such secondary nature texts as well.

Published: January 2018

Abstract
After checking the success of the biosorption process to remove heavy metals from wastewater using olive tree pruning as a cheap biosorbent in the laboratory scale, the scale-up is necessary to progress towards industrial applications chance. The aim of this work was the study of the effect of scale-up in the process of biosorption of Pb(II) with olive tree pruning in a packed bed column. Experiments were performed using two different scale-up criteria and results obtained in both scales were compared. Similar parameters were obtained for each pair of equivalent tests, with a slightly advanced of the obtained breakthrough curves in the pilot plant. The experimental results were fitted by the Thomas model and the obtained mean values were KTh = 0.187 mL/min·mg and q0 = 20.59 mg/g for criterion 1 and KTh = 0.217 mL/min·mg and q0 = 20.27 mg/g for criterion 2. Finally, the mathematical model was applied to simulate industrial applications and it was obtained that under optimal operative conditions, a column according to the criterion 1 was able to operate 2.3 h, and a column according to the criterion 2 was able to operate for 3.6 h.
Evaluation of Nanotechniques and Conventional Techniques for the Removal of Dioxins
Authors: Shahare Vaishali V. , Grover Rajni , Meena Suman 
Published: January 2018

Background:
The persistent dioxins/furans has caused a worldwide concern as they influence
the human health. Recent research indicates that nonmaterial may prove effective in the degradation
of Dioxins/furans. The nanomaterials are very reactive owing to their large surface area to
volume ratio and large number of reactive sites. However, nanotechnology applications face both the
challenges and the opportunities to influence the area of environmental protection.

Objective:
i) To study the impact of oil mediated UV-irradiations on the removal of 2,3,7,8-TCDD,
2,3,7,8-TCDF, OCDD and OCDF in simulated soil samples.

ii) To compare the conventional treatment methods with the modern available nanotechniques for the
removal of selected Dioxins/furans from soil samples.

Methods:
The present work has investigated an opportunity of the degradation of tetra and octachlorinated
dioxins and furans by using oil mediated UV radiations with subsequent extraction of respective
dioxins/furans from soils. The results have been compared with the available nanotechniques.

Results:
The dioxin congeners in the simulated soil sample showed decrease in concentration with
the increase in the exposure time and intensity of UV radiations. The dechlorination of PCDD/Fs using
palladized iron has been found to be effective.

Conclusion:
Both the conventional methods and nanotechnology have a dramatic impact on the removal
of Dioxins/furans in contaminated soil. However, the nanotechniques are comparatively costlier
and despite the relatively high rates of PCDDs dechlorination by Pd/nFe, small fraction of the
dioxins are recalcitrant to degradation over considerable exposure times.
Broadening the Definition of Collusion? A Call for Caution
Authors: Beaton-Wells Caron , Fisse Brent 
Published: January 2018

In Australian competition law, the notion of collusion between competitors is encapsulated in the concepts of ‘contract’, ‘arrangement’ and ‘understanding’ under the Trade Practices Act 1974 (Cth) (‘TPA’). These concepts have been integral to the civil prohibitions on cartel conduct under s 45(2) of the TPA since 1974. The same concepts are used in the new cartel offences and civil per se prohibitions which took effect in July 2009 as a result of amendments made by the Trade Practices Amendment (Cartel Conduct and Other Measures) Act 2008 (Cth).In 2007, the Australian Competition and Consumer Commission (‘ACCC’) recommended amendments to the TPA in connection with the interpretation of ‘understanding’ in the wake of its largely unsuccessful cases against petrol retailers for alleged price fixing in Ballarat and Geelong and its subsequent petrol pricing inquiry. In this article it is argued that the proposed amendments should be rejected.
Broadening the Extraterritorial Reach of Australia's Cartel Prohibition: Adopting the ‘Effects’ Doctrine without the Negative Effects
Authors: Duke Arlen 
Published: January 2018

In an increasingly global economy, foreign anti-competitive practices pose just as much of a threat to the economic wellbeing of Australians as domestic anti-competitive practices. Multinationals which transcend national boundaries are now major players in many different markets. Furthermore, continuing globalisation means that the number of commercial activities with transnational implications will rise.The Trade Practices Act 1974 (Cth) (‘TPA’) contains a provision that expressly gives the Act extraterritorial operation. Section 5(1) provides that the competition law prohibitions contained in Part IV extend to conduct engaged in outside Australia by bodies corporate incorporated, or carrying on a business, in Australia. With the exception of the prohibitions against cartel conduct, the extraterritorial operation of the prohibitions against the major forms of anti-competitive conduct is even broader. Since the Act’s inception, the prohibitions against price and non-price vertical restraints have extended to the engaging in conduct outside Australia by persons and bodies corporate (whether incorporated, or carrying on a business, in Australia or not) in relation to the supply of goods or services to persons within Australia.
Political Freedoms and Entitlements in the Australian Constitution — An Example of Referential Intentions Yielding Unintended Legal Consequences
Authors: Emerton Patrick 
Published: January 2018

This article is about the interpretation of legal texts. Its immediate aim is to defend, against a certain sort of originalist objection, the well-known cases that hold that the Australian Constitution, by implication, guarantees certain political freedoms and entitlements. That is not to say that the article intends to vindicate the outcome of every one of those cases – rather, it intends to vindicate the general methodology and orientation of those cases as stated by the High Court in Lange v Australian Broadcasting Corporation.The general character of the originalist objection I have in mind is that no implication (other than perhaps a strictly logical implication) can be drawn from a legal text which is at odds with the actual intentions of the authors of that text.

Published: January 2018

Objective: The main objective of periodontal therapy is tissue regeneration. Previous studies have identified the potential of mesenchymal stem cells to improve major periodontal defect reconstruction in bone tissue engineering. Cell sheet technology (CST), in which a cell culture is obtained from a material coated with a temperature-sensitive substrate, has been developed for the reconstruction of various tissues, including periodontal tissue. Cementum protein-1 (CEMP-1) is a 50-kDa protein that plays a crucial role in cementogenesis by enhancing the combining of cells formed by cell cementoblast. Evaluate periodontal tissue regeneration with CST, and the application of chitosan, chitosan cell sheet or arginineglycineaspartic acid (RGD)-modified chitosan cell sheet on Macaca nemestrina one-wall defect model.Methods: The CEMP-1 was analyzed expression in a sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) gel electrophoresis assay.Results: CEMP-1 expression in gingival crevicular fluid was observed using the SDS-PAGE method every week for 3 weeks. Protein band expressions on SDS-PAGE gel were identified at around 50 kDa with different thicknesses between groups. The chitosan, chitosan cell sheet, and RGD-modified chitosan cell sheet groups showed protein bands of CEMP-1 between 50 and 70 kDa at weeks 1, 2, and 3; weeks 2 and 3; and weeks 1 and 2, respectively.Conclusion: Our results demonstrated that the application of chitosan and RGD-modified chitosan cell sheets could enhance bone regeneration, as evidenced by CEMP-1 protein expression levels.
