Propuesta didáctica de análisis de la imagen audiovisual aplicada al documental “las estatuas también mueren” / Didactic proposal of analysis of audiovisual images applied to documentary "statues also die”
Authors: Revilla Carrasco Alfonso 
Published: June 2017

Así como la comprensión de la imagen fotográfica requiere de un sistema de registro que nos permita considerar los parámetros de análisis de forma sistemática, más aún sucede cuando nos enfrentamos con la imagen audiovisual (documental, cine, etcétera). Este artículo presenta una propuesta de análisis audiovisual aislando los fotogramas clave y analizándolos en una sucesión que parte de parámetros de análisis de la imagen fija. La fotografía a menudo supone la concreción de una sucesión de imágenes que permanecen en acto, esto es, la síntesis de una sucesión de imágenes. La elección del fotograma clave que contiene los parámetros de análisis, nos permite conjugar un sistema de análisis de imagen fija para imágenes audiovisuales. El artículo presenta tanto los parámetros de análisis, como una propuesta de aplicación práctica, analizándose las dos primeras secuencias del documental Las estatuas también mueren (Chris Marker, Alan Resnais y Ghislain Gloquet, 1953), donde reivindica un acercamiento crítico al etnocentrismo aplicado a las manifestaciones artísticas negroafricnas.

Background. Fracture shaft of femur in pediatric age group is one of the most common leading emergencies. Children in the age group of 6-14 years are treated with either traction, hip spica, flexible/elastic stable retrograde intramedullary nail, or external fixators. We conducted a clinical prospective study on the use of Titanium Elastic Nailing System (TENS) for the treatment of femoral shaft fractures in children.
Methods. The prospective study included 45 cases of fresh femoral shaft fractures. The Inclusion Criteria were a) Age group of 6-14 years, b) Recent fracture of femur shaft c) Transverse, short oblique, minimally comminuted fractures.
Results. The clinical results were evaluated using Flynn’s criteria of scoring as, Excellent in 40 patients (88.89 %), Satisfactory in 5 patients (11.12 %) and poor in none. Radiological criteria for fracture union were assessed by using Anthony et al scale. Nine patients developed bursitis at entry point of the nail. Three patients had superficial infection due to bursitis. Full weight bearing was possible in mean time of 8.7 weeks (range; 7-12 weeks).
Conclusion. TENS is very effective in management of paediatric shaft femur fractures in the age group of 6-14 years with advantages of early union, early mobilization and manageable complications.

Background. Dysplasia of hip joints and congenital hip dislocation are common impaired developments in newborns. Currently, there are common cases of late detection of the disease, failure in treatment, and development of complications, which is not adequately reflected in the modern literature.
Aim of the study. This study aimed to identify the most common errors during diagnosis and treatment onset in children with congenital hip dislocation during the first year of life.
Materials and methods. This study is based on a retrospective analysis of the anamnesis history, which is the history of diagnosis and previous treatment, as well as on clinical, sonographic, radiation, and magnetic resonance examinations of 250 patients aged 5 months to 2 years. The patients were admitted to the specialized Department of Hip Joint Pathology of the Turner Scientific and Research Institute for Children’s Orthopedics with a diagnosis of congenital hip dislocation between 2005 and 2015.
Results and Conclusion. The most common causes of errors during diagnosis of congenital hip dislocation in children are the lack of examination of the newborn by an orthopedist in the maternity hospital and sonographic screening as well as an error in its implementation. At the onset of treatment, the use of structures that did not provide the optimal position for repositioning the femoral head was noted as well as late indications for primary surgical treatment in cases of unreducible hips.

<p class="abstract"><strong>Background:</strong> <em>Staphylococcus aureus </em>is a medicologically important pathogenic bacteria which is largely responsible for the thousands of human health hazzards. This study investigated the incidence of <em>Staphylococcus aureus </em>in various clinical samples from in- and outpatients attending Islami Bank Hospital, Rajshahi, Bangladesh.</p><p class="abstract"><strong>Methods:</strong> Clinical isolates from the hospital was confirmed as <em>Staphylococcus aureus </em>using standard bacteriological techniques. This study reports the isolation and identification of <em>Staphylococcus aureus</em>, coagulase negative staphylococci and catalase negative cocci in clinical samples at Islami Bank Hospital, Rajshahi, Bangladesh. </p><p class="abstract"><strong>Results:</strong> Out of a total of 144 putative isolates of Staphylococci from urine, ear and wounds screened for <em>Staphylococcus aureus</em>, 87 of them were confirmed as <em>S. aureus</em>, 30 were coagulase negative staphylococci while 27 were catalase negative cocci. The high incidence of <em>S aureus </em>in this study compared to other staphylococci demonstrates the versatility and propensity of <em>S. aureus </em>to cause diseases.</p><strong>Conclusions:</strong> This is worrisome because of the high mortality and morbidity often associated with infections of this bacterium. It therefore calls for proper handling of specimen suspected to contain the organism or patients who might be at risk of infection. This is to avoid transmission to other patients and healthy individuals especially health workers as they might constitute vehicles for the spread of the organism. Further studies are recommended because of the small sample size in this study. This would help to establish whether this was peculiar to the Islami Bank Hospital Rajshahi, Bangladesh or wide spread in other hospitals in the country.

Muralismo libertário: comunicação e educação emancipadora
Authors: Pinheiro Queluz Marilda Lopes , Queluz Gilson Leandro 
Published: June 2017

RESUMO Este trabalho pretende, através do exemplo do muralismo libertário latino-americano, problematizar as relações entre educação e emancipação. É nossa compreensão que as práticas de ação direta pertinentes ao muralismo libertário, são processos constituintes de uma comunicação igualitária em franca antítese e resistência a um modo de comunicação autoritário característico da sociedade capitalista e de sua indústria cultural. Analisaremos algumas obras dos coletivos muralistas anarquistas contemporâneos nas cidades latino-americanas, demonstrando sua orientação temática, suas estratégias de produção e representação imagética, e sua concepção explícita de uma formação cultural ampliada. Consideramos que o muralismo libertário, ao se apropriar do espaço urbano como meio de comunicação, ao ressignificar nos muros os demarcadores das desigualdades sociais, procura constituir uma cultura da resistência, materializando os fundamentos de um modo de comunicação igualitário. Palavras-chave: Muralismo Latino-americano. Muralismo Libertário. Educação e Emancipação. ABSTRACT The following paper aims to problematize the relationship between education and emancipation through the example of Latin American libertarian muralism. It is the authors’ understanding that the practices concerning the libertarian muralism belong to an egalitarian communication, which is openly against an authoritarian communication peculiar to the capitalist society and its culture industry. The authors will analyze some studies of the contemporary anarchist collective muralists in Latin American cities, demonstrating their thematic orientation, their strategies of image production and representation, and their explicit conception of a broad cultural formation. In addition, the authors consider that libertarian muralism, by using urban space as a means of communication, and re-defining the main aspects of social inequalities, seeks to establish a culture of resistance, materializing the foundations of an egalitarian way of communication. Keywords: Latin American Muralism. Libertarian Muralism. Education and Emancipation.
Examining the Effects of Advanced Cutting Methods on Surface Porosity of Aluminum Foam Material
Authors: Dahil Lutfiye 
Published: June 2017

Abstract—In this study, the aluminum foam material having two different pore structures was obtained. These materials were cut using advanced cutting methods (waterjet and wire erosion). And then, the porosity levels of the cut surfaces were examined depending on the cutting method applied. In order to ensure the equal measurement, the rate of feed was set to 40m/min. The porosity measurements were repeated for 6 times in parallel and vertical to cutting surface, and the mean value of those measurements was calculated. There were also problems with the two cutting methods. Both methods require additional processing. In terms of continuity of the cutting process, water jet is more advantageous. Water jetting in high and medium pore specimens yielded better results in places parallel to the cutting surface. It was the result of water jetting better at places that are perpendicular to the cutting surface.
Key words: Aluminumfoammaterial, Advanced cuttingtechniques, Pore, Surfaceroughness.
Strategy Planning For the Mining Industry in Semnan Province (Iran) Using A Combined SWOT-AHP Approach
Authors: Rafeeian Nima , Taji Mohammad 
Published: June 2017

Abstract— In today's world, the type of investment, prioritization and scheduling the extraction of mineral resources due to the constraints of resources, technologies and human resources, etc. strongly requires a strategic planning appropriated in this area. In terms of quantity and quality, the resources and mines in Semnan province would be seen among the richest mineral resources in Iran. However, due to a scarcity of compiled strategic planning in the mining industry, this prominent province plays a small role in the country's economic developments. In this regard, the exploration and evaluation of the strategic factors and a formulation of strategies seems to be vital. In this study, the analysis and formulation of the demanding strategy have been done by applying the strategic management approach SWOT (Strengths, Weaknesses, Opportunities and Threats). Then the resulting strategies have been prioritized by using a hierarchical multi-criteria decision analysis called AHP (Analytic Hierarchical Process). Three strategies: creation of industrial clusters in the field of handicraft production with raw materials of mud, clay and gypsum panels (S3), joint mineral investments with the other mines of the province (S8), and the creation of groundwork for the mineral production cooperative companies, gained the highest priorities. Three strategies: updating the existing coke-making companies and constructing small coke-making and coal-washing units (S5), forming the specialized, industrial, mining, strategic and advisory committees in the Semnan Provincial Government to facilitate the local laws and encourage investments in mining (S7), and a greater engagement of private sectors with the government (activate the role of mining engineering and a maximum participation in decision-making related to the industry of the province) gained the least priority. At last, using prioritized strategies, some systematic planning is chosen strategically to suit the current situation, and to make possible a development and utilization of the high potential capacities in the mining industry which are already provides in Semnan province.

Thermal Analysis of a Solar Cooling Adsorption System by a Dynamic Model
Authors: Vollaro Roberto de Lieto , Basilicata Carmine , Vollaro Emanuele de Lieto 
Published: June 2017

Abstract—In this paper is shown the possibilities to implement an energy solar system, without auxiliary elements, made to cool. The new technologies (vacuumpacked tube, tanks of build-up with variable volume, etc.), allow the possibility to obtain easily a stand-alone refrigerating system. Today it is always more and more the case where during the summer season there is a surplus of thermal energy whose use is to be assigned within the energy optimization system. The most immediate solution to this problem is the ability to produce cold by means of simple adsorption solutions, thus contributing to the cooling problem with low COP values. The most beneficial adsorbent both for its thermal/physical and low cost is the silica gel, a polymer of silicon dioxide, commonly used for its dehydrating properties, especially in the preservation of electronic material [1,3,13].
In this study we have developed a dynamic model with the software trnsys to verify the obtaining of appropriate warm fluid for an innovative cooling system absorption with gel of silica and water and it is tested on a real building as case study.
The dynamic model analyzes the performance thermodynamic balance of a small size system has been made (about 20-50 kW), adequate to cool a Building of 900 sq m. and allow to assess the conformation (surface, storage volume, etc.). of a new generation solar power plant is able to guarantee a continuous operation during the summer period [2].
We have tested a solar cooling system with solar vacuum collectors on a real Building with Meteo data of three Cities as Rome Milan and Tunisi and we have tested the model comparing the results obtained.
The model in fact allows to make a preliminary design of principal part of the plant and to evaluate function cost-benefit of a complex investment for innovative technology The interesting results obtained allow at a later stage to make a prototype validating the theoretical results with experimental measures.

Hybrid Road Barrier Design As Aesthetic Safety Feature and Urban Furniture
Authors: Yumrutas H. Ibrahim , Yorur Huseyin 
Published: June 2017

Abstract— There are various types of road barriers such as steel W beam, steel cable, concrete and wooden (timber) that have been used all over the World. They all have some advantages and disadvantages from different kinds of aspects such as construction time, ease of installation, low-cost, proven effectiveness, impact resistance, durability, service life, maintenance, etc. but to attain a more pleasant drive especially in historical and natural urban roads or scenic highways, installing wooden (timber) barriers can be considered as a more aesthetically pleasing alternative. In addition to aesthetic, wooden barriers can be preferred for their impact energy and sound absorption capabilities especially in urban roads. With the design, it is also estimated that light effect of oncoming traffic will be blocked. The main idea is to use hybrid barriers for both aesthetic safety feature in scenic or historical roads and urban furniture. This paper also summarizes comparisons among conventional road barrier systems considering the European standard EN 1317, Road Restraint Systems and provides a discussion of future designs.

“Islamic Revival” in Dagestan: 25 years later
Authors: Bobrovnikov Vladimir 
Published: June 2017

More than twenty five years passed from the beginning of the Islamic growth in Dagestan. It is the time to evaluate this phenomenon. As specialist in Oriental studies and social anthropology I am going to do it on the basis of archival and field research materials gathered in the republic from the autumn 1992 till the summer of 2016. I happened to witness the very beginning of the Islamic growth as well as fall of enthusiasm related to Islam. This paper aims to clarify the nature and results of the Islamic growth. What was the reason of the so-called Islamic revival? How does it correlate to the imperial Soviet past in Russian Caucasus? What did the Islamic growth result in? What was eventually revived if any? And last but not least — how was the return of Islam to public sphere related to the growth of conflicts and social instability in the region? The fall of the one-party Soviet system was accompanied with the appearance of numerous Islamic parties and movements. All of them appealed to the restoration of religious freedom for Muslims, the return from the official state atheism to Islam, consolidation of Russia’s Muslims on the basis of Shari‘a and to the revival of high pre-Soviet Islamic culture in perspective. Post-Soviet Islamic parties appeared to be strikingly short-lived: all of them disappeared already in the 1990s. Hopes on Islam as the means of political liberation and national self-determination of Soviet Muslims in Dagestan proved to be wrong. Politics seems not to be a stable factor of the Islamic growth. Religious statistics defines it better. One should note unprecedented growth of religious Islamic institutions in Dagestan. However the quantity does not mean quality. Islamic cultural revival did not yet happen in the republic. It seems that the Soviet past still affects Dagestani Muslims stronger that it seems at first sight. Following Soviet reforms and forced secularization pre-revolutionary Muslim society exists no more. The general course of the Islamic growth was much affected by transformation of post-Soviet Russian polity in the region, economic devastation, growing unemployment and aftermath of two bloody Russian-Chechen wars. In addition, the so-called Wahhabi opposition appeared to be a serious challenge to the post-Soviet Russian rule in the Caucasus. Nowadays it disappears but other radical Muslim movements such as Hizb al-Takhrir were introduced in the region.
