Ameloblastic Fibroma Associated With Impacted 3rd Molar: A Case Report
Authors: K Indira Priyadarshini  , Karthik Raghupathy  , K V Lokesh  , B Venu Naidu
Published: July 2019

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar.
Understanding Primitive Reflexes and Their Role In Growth And Development: A Review
Authors: Manojkumar Jaiswal  , Rahul Morankar
Published: July 2019

Reflexes are set motor responses to specific sensory stimuli. In newborns and young infants these primitive reflexes are an important assessment tool. Children with a distinctive reflex are difficult to treat. This includes a large category in which primitive reflexes are retained longer than necessary. Certain reflexes may not appear at appropriate age of development. Many neurological conditions are characterized by aberrations in reflex actions. However, there is scarcity of data for high-risk infants pertaining to this topic. Dental treatment becomes challenging in these individuals and sometimes due to lack of compliance even necessary emergency dental treatment is difficult to carry out.

Published: July 2019

The problem of population decline, economic activity decrease and deterioration of investment attractiveness has become topical on the agenda of sustainable development of industrial or single-industry cities in most developed countries (uSA, Eu, Australia) during the last century. New urban trends are increasing of the economic efficiency of urban areas usage, encouraging restrain of the population, including youth and employable people, and attracting new ones through the creation of required jobs and the formation of comfortable living conditions. All of these demanded the mechanisms and tools development for the social and economic development of cities. world experience has accumulated various approaches to the transformation of shrinking cities —  economic and financial instruments supporting the development and provision of partnership of key stakeholders of cities, integrated urban development programs, tools for optimizing the spatial and territorial structure of cities, etc. The paper analyzes the existing practices of application of administrative and organizational mechanisms for the spatial development of shrinking cities in the united States, Britain, Germany, Spain and Australia. Based on the analysis, key conclusions are drawn about the factors that divide the trajectories from decline to the cities restoration. The practical significance of the conclusions lies in the possibility of using them in the development of strategies and programs for the russian cities development that are experiencing a tendency towards a contraction of economic and territorial space.
The Practical Wisdom of Aristotle in the Era of Postmodernism (Managing China’s Sports Reform)
Authors: Altukhov S. V.
Published: July 2019

The end of the twentieth century was marked by the extensive and explosive development of two directions in the economy and culture of society — globalization and postmodernism. The postmodern is an aggressive and protest reaction to a modernist style. Modernists believed up to nowadays that reason, science, progress, self-sacrifice, respect are eternal values. However, the creation of a global consumer society, informatization, the development of new technologies, the Internet spread, mobile communications, social networks contributed to the emergence of new relations associated with the rejection of traditional values. The economy is being actively taken root into the culture of consumption in the service industry. Fashion, style, behavior standards, brands have become a commodity. Postmodern crosses culture to commerce, with consumption, liberates and releases instincts. At the same time, the newly-minted cultural mutants are characterized by imaginary identity, indifference and disunity. After the end of the Cold War, postmodernism ideas had been moved ahead over the different countries and continents successfully, until they had stumbled over China. The managerial problem of the human relations and impossibility of their measurement is shown in modern conditions as well as at the time of Platon, Aristotle, Lao-tszy, Confucius, Suntszy, etc. This phenomenon is considered by us by the example of sports development and mass culture in China. In a situation with the penetration of postmodernism into Chinese society, Chinese communist leaders are forced to address the practical wisdom of their ancestors to counter the destruction of national consciousness and the preservation of national identity. Sports has become one of the most accessible, important and capital-intensive mechanisms for the implementation of global projects. Commercialization and capitalization of major sporting mega events has become a part of political activity, national prestige in the international arena for many political systems and independent states. Several case studies illustrate how as well as how Chinese leaders try to preserve national identity and the balance of relations in society in the postmodern era using the example of the development of China’s sports reform.

Authors: Santos Carlos Antonio Costa dos , Lima Jeane Rafaele Araújo
Published: July 2019

O estudo tem como objetivo principal estimar os fluxos de energia à superfície e analisar a evolução das possíveis ilhas de calor urbano na região metropolitana de Manaus-AM, comparando o ano 1990 e 2011 e relacionando a retirada da cobertura vegetal com a intensidade desse fenômeno, utilizando técnicas de sensoriamento remoto. Para a realização deste estudo foram utilizadas imagens do satélite Landsat 5-TM, dados meteorológicos oriundos do INMET e aplicado o algoritmo SEBAL para obtenção dos componentes do balanço de energia à superfície. Observou-se que o sensoriamento remoto se apresenta como ferramenta promissora no estudo da dinâmica das cidades, assim como, dos efeitos da expansão urbana nos fluxos de energia entre a superfície e a atmosfera e, que a substituição de superfícies vegetadas por materiais utilizados nas áreas urbanas resultam em redução da energia utilizada no processo de evaporação e aumento da energia para aquecimento do ar e do solo, ocasionando aumento das temperaturas. AbstractThe main objective of this study was to estimate the surface energy fluxes and to analyze the evolution of the possible rban heat islands in the metropolitan area of Manaus-AM, comparing the years 1990 and 2011 and relating the retreat of the vegetable covering with the intensity of that phenomenon by using remote sensing techniques. This study used images from Landsat 5-TM satellite, as well as, meteorological data originated from INMET and applied the algorithm SEBAL for obtaining of the components of the energy balance. The remote sensing technique is a promising tool in thestudy of the dynamics of the cities, as well as, of the effects of the urban expansion in the energy fluxes between the surface and the atmosphere. The change of vegetated surfaces by materials used in the urban areas results in a reduction of the energy used in the evaporative process and increase the energy for heating of air and soil, causing increase of the temperatures.

Responses of Apple Plants to Salinity Stress
Authors: ARAS Servet , EŞİTKEN Ahmet
Published: July 2019

Salt stress is a common agricultural problem that
affects both quantity and quality of fruit crops. Responses of rootstocks
against salinity possess importance due to demonstrating stress tolerance.
Little is known about the early responses of apple plants to short term
salinity. In our study, we investigated the physiological responses of an apple
plant cv Fuji grafted onto M9 and MM106 rootstocks against 35 mM NaCl stress.
After 1 month, salt-treated plants exhibited decreased chlorophyll content
(SPAD). Salt stress decreased stomatal conductance values of Fuji/M9 and
Fuji/MM106 by 17.0 and 30.1%, respectively when compared with own control.
Membrane permeability decreased by 21.3 and 22.0% in salt-treated Fuji/M9 and
Fuji/MM106, respectively compared with own control. Reduction due to salt
stress in SPAD value, stomatal conductance and leaf relative water content and
increase in leaf temperature and membrane permeability were greater in
Fuji/MM106 than in Fuji/M9, suggesting that under short term salinity toxic
effects of  NaCl were less in Fuji/M9.

Published: July 2019

Zeytin (Olea europaea L.) Akdeniz havzasında
tarımı yapılan en eski türlerden birisidir. Meyvesi, yağı ve diğer yan
ürünleriyle insan sağlığı açısından önemli olan zeytin, ekonomik önemi ile de
binlerce yıldır insanlığa hizmet sunmaktadır. Kültür zeytini (Olea europaea var. europaea), Oleaceae
familyasından Olea cinsine aittir ve
Türkiye’de yetiştiriciliği yapılan 90 kadar yerli çeşidi mevcuttur. Bu çeşitler
ile yabani zeytin formları arasında meydana gelen diğer ara formlar geniş bir
genetik çeşitlilik oluşturmaktadır. Fertil bireyler ve birçok varyete yüksek
derecede heterozigotluk gösterir. Bu durum çeşit doğrulamasını
zorlaştırırken, yabancı tozlanma ile birlikte durum daha da karmaşık hal
almaktadır. Yanlış etiketleme, sinonimler, yerel isimlendirme gibi birçok
sebepten dolayı çeşitlerimizin ve bu farklı formların filogenetik ilişkileri
tam olarak aydınlatılamamıştır. 1990’lı yıllara kadar çeşitler morfolojik
özellikleri ile tanımlanmış ve birbirlerinden ayrılmıştır. Teknolojinin
gelişmesi ve biyoteknolojik yöntemlerin tarımda kullanılması ile bu sorun bir
ölçüde çözümlenmeye başlamıştır. Moleküler markörler ile çeşitlerin
ayrılabilmesi ve genetik uzaklıklarının tespiti üzerine dünyada ve ülkemizde
yapılan çok sayıda araştırma mevcuttur. Ancak bu çalışmaların sonuçları arasında
da bazı farklılıklar bulunmaktadır. Bu makalede Türk çeşitlerinin yer aldığı araştırmaların

Published: July 2019

This study was conducted
to determine dry plant weight and quality traits of chicory (Cichorium intybus L.) genotypes collected from eight provinces and 29
locations in Turkey. Field experiment was conducted in Yozgat conditions for
two years (2015-2016 and 2016-2017) and the observations were performed in the
second year. Dry plant weight, crude protein ratio and protein yield (g plant-1),
ADF, NDF, K, P, Ca, Mg contents and K/(Ca+Mg) and Ca/P ratio were determined in
chicory genotypes as yearly total or average. Total dry plant weight and average
crude protein content ranged between 167.80-564.60 g plant-1 and 11.85-16.60%, respectively. The highest
potassium content was determined as 2.442%, while it was lowest as 2.022%. The
phosphorus, calcium and magnesium content ranged between 0.367-0.413%,
0.963-1.232% and 0.250-0.407%, respectively. As a result, significant
differences were observed among the chicory genotypes for all the traits. Such
a variation even in the restricted area is point out the high variation in
Turkey. These differences encouraged to new studies on chicory in Turkey and
were also promising for improving new varieties.
An Efficiency-orientated Total Factor Productivity Measurement Model for Construction Projects
Authors: Zhan Wenting , Pan Wei
Published: July 2019

Modularization and mechanization are widely promoted due to their potential benefits in enhancing site efficiency. However, the outcomes of the implementation lack quantitative supports at the project level. This paper aims to develop a quantitative evidence-based methodology for measuring site efficiency and evaluating the outcomes of the two technologies. Applying the proposed methodology to a real-life building construction project, the simulation results of multiple scenarios show that site efficiency is likely to be enhanced by encouraging the utilisation of laboring-saving materials and equipment within the limited project budget. The findings provide quantitative evidence to encourage technological innovation in construction materials and equipment, thereby demonstrating the potential of substituting materials or equipment for labor in benefiting site efficiency of a construction project through adopting modularization and mechanization.

Authors: Zhang Nan , Tian Yichen , Al-Hussein Mohamed
Published: July 2019

Building Information Modeling (BIM) design becomes popular with the growing needs of enhancing construction efficiency. During the design process, 3D Modeling is the foundation of generating and analyzing building information. The modeling tool, Autodesk Revit, automatically creates log files, which can record all design activities. This paper investigates and analyzes the operation data from unstructured temporal Revit log files. These data were recorded when executing the general and external command to build a 3D model of a typical residential two-story building. The objectives of this analysis were to figure out the influence elements of producing a good framing model and to give some suggestions for improving modeling efficiency. In order to extract the useful specific commands, the information in the text journal file was transferred to an excel file, before reading by a data mining tool, RapidMiner. It generated a pie chart to show the repetition amount of modeling activities. Analyzing the reasons of repeating some commands frequently, this paper contributes the possibility to reduce the useless repetition for building a good 3D model.

Cyclic Behavior of a Bamboo-Steel Hybrid Moment Frame with a Novel Energy Dissipation Connection
Authors: Huang Zirui , Huang Dongsheng , Wang Yanhua , Feng Yan
Published: July 2019

This paper presents a novel bamboo/wood-steel hybrid frame which uses engineered bamboo products as beams and steel as columns. The beams and columns are jointed by an innovative connection which incorporates a steel hinge and two steel brackets to carry shear force and moment from the end of beam, respectively. The bracket consists of two segments, i.e. joint segment connected to beam and the other segment, which serves as energy dissipation panel (EDP), connected to the columns via a base panel. By this way, the connection can provide sufficient initial stiffness for serviceability requirements and excellent energy dissipation capacity for seismic performances. Lateral cyclic loading tests were conducted to investigate the seismic performances of the frame. It was found that hysteresis loops of the frame with energy dissipation joints show less pinching than that of frames with dowel- or bolt-type connections; by proper designing, the damage and failure of the frame can be restricted in the EDPs of connections, whereas virtually no damage was observed in the other components of the frame; the connection can provide more than 10 % damping for the frame after the yielding of EDPs. Design method is also proposed in this paper.

Authors: Ismaiel Maysoun , Chen Yuxiang
Published: July 2019

Air leakage is one of the main influencing factors in buildings’ thermal performance. The adverse effects of poor air leakage include higher energy costs, consumption in space heating and cooling, poor thermal comfort, corrosion, and the growth of molds due to air leakage induced condensation. The main objective of this study is to investigate the characteristics of air leakages of Canadian homes related to construction methods, age, size and climatic zones. The air leakage test results of 226,000 dwellings in three provinces of Canada were analyzed. Statistical analysis was utilized to compare the mean of air leakage with respect to different factors. Generally, the air leakage decreased by 40% in the period from 1960 until 2018, which has shown a remarkable effect of new construction techniques on air leakage. Investigations also indicated that the average air leakage rate of homes constructed by using the onsite technique is approximately 25% to 60% higher than those prefabricated in modular or panels, varying with respect to the workmanship and construction quality control. This study concluded that the prefabricated construction techniques could decrease the air leakage rate significantly, which will have a remarkable effect on buildings’ thermal performance as well as home’s heating and cooling costs. The findings contribute to estimating the effects of influencing factors on air leakage, also it is useful in performance simulations, HAVC sizing and energy management. And recommend the use of the prefabricated in modular or panel’s construction method to achieve better and acceptable air leakage performance.
Numerical Study of the Geometry Effect of Notched Connections in Mass Timber Panel-Concrete Composite Floors
Authors: Zhang Lei , Chui Y H
Published: July 2019

A mass timber panel-concrete (MTPC) composite floor system consists of a timber panel in the tensile zone, a concrete layer in the compression zone, and shear connectors between timber and concrete. The notched connections that are cut in timber and connected with concrete by the interlocking effect are often classified as the best type of connection system in terms of stiffness and load-carrying capacity. To study the effect of notch geometry to the performance of notched connections and composite beams, 2D finite element models are built in ABAQUS in this study. The concrete portion is modelled with concrete damaged plasticity model while the timber portion is modelled with Hashin’s failure criteria. The effective bending stiffness and ultimate bending capacity of the composite beam under uniformly distributed load are obtained from the finite element models and are compared with the well-known Gamma method in Eurocode 5 and strut-and-tie model. Good agreement between finite element model in the elastic range and strut-and-tie model was achieved. However, due to the assumptions made in the Gamma method, it was found that this simplified design method is not capable of describing MTPC composite floors with discrete notched connections.

Authors: Dakhli Zakaria , Danel Thomas , Lafhaj Zoubeir
Published: July 2019

This paper provides a design of the Information System architecture to support a connected construction site. In order to master the diversity and the complexity of construction site processes, theories are needed that separate the stable essence of the smart construction site from the variable way in which it is realized and implemented. For that, construction site processes were mapped before linking each data path with the existing technological tools using correspondence matrixes. The results enable the definition of a proper system able to deal with the resources allocated to the construction process functionalities. The main challenge faced in this research was to identify which pertinent data is needed that activates the resources to complete each given construction task.
Applying Virtual Reality to Improve the Construction Logistics of High-rise Modular Integrated Construction
Authors: Cheung Enoch H.L. , Ng S. Thomas
Published: July 2019

Modular and offsite construction is becoming increasingly popular around the world. In Hong Kong, a modular integration construction (MiC) method is identified as a pragmatic approach to speed up the housing construction program and to solve the productivity and manpower problems of the industry. Using the MiC, virtually all the construction works including the finishing as well as the mechanical and electrical installation are completed offsite. The MiC units are then delivered to and installed on site. While the MiC can shift the risks of construction projects to the factories, this construction method is not without challenges. This is particularly the case for Hong Kong as most of the construction sites in the city are cramped due to the high-density urban environment. The problem is aggravated when every modular unit is unique and they are time consuming to produce. Any damages to the MiC components during the lifting process could seriously affect the entire construction sequence under a just-in-time management philosophy. Therefore, it is imperative to plan and monitor the logistics carefully when the MiC technique is used. To reduce any human errors and increase the efficiency and accuracy of the lifting process, a virtual reality (VR) approach may be adopted to simulate the construction logistics of MiC construction and train the crane operators. In this paper, a VR model is developed to simulate the construction of a high-rise residential building in a confined site. Various functions are built into the VR model to support the decisions pertinent to lifting logistics planning. In this paper, the design considerations and functions of the VR model are identified through a series of interviews. Moreover, the validation interviews help unveil the potentials and pitfalls of the developed VR model.
A Research Roadmap for Off-Site Construction: Automation and Robotics
Authors: Bowmaster Jeremy , Rankin Jeff
Published: July 2019

The development of a research roadmap was undertaken to further the activities of a joint industry-university-government initiative in off-site construction research in Canada. The roadmap identifies the general research areas of structural design, construction materials, building science, advanced manufacturing, logistics and transportation, automation and robotics, and digitized construction. The development of the roadmap included a broad literature review of peer reviewed academic journals, select conference proceedings, and industry publications. The review of recent research in these areas was analyzed from the perspectives of application area, technology area and innovation phase. The purpose of the analysis was to identify the current activities and opportunities for further research. For example, in the area of automation and robotics, the results showed the majority of construction automation research relates to the actual production phase, as opposed to planning or operations. In terms of innovation maturity, little research is being undertaken with respect to the implementation and adoption of automation technologies, and very little research in technology development or prototyping. In addition, applied research is being conducted at approximately half the rate of basic research. A more recent trend has been greater research interest in industrial production technologies, particularly in additive manufacturing. Very little research is being conducted with respect to non-robotic cyber-physical systems including, IoT connectivity, drone technologies, or construction focused actuator and manipulator technologies. This paper will discuss the broader results of the research roadmap with a focus on automation and robotics.
