SIZE COMPOSITION AND GROWTH RATES OF BLUE KING CRAB PARALITHODES PLATYPUS BRANDT, 1850 IN THE RUSSIAN SECTOR OF THE BERING SEA
Authors: Fedotov P. A. , Chernienko I. S.
Published: July 2019

Size composition and growth rate of blue king crab males are analyzed on the data of 8 bottom trawl surveys conducted in the western Bering Sea in summer-fall seasons within the period from 2005 to 2017. Significant changes in size structure of this population are revealed. Portion of commercial males was the lowest (18.7 %) in 2010 because of the strong yearclass appeared in the catches in 2005, when its males carapace had the width 20–40 mm, that provided in 2008–2010 the percentage of juveniles with the size < 100 mm about 59–60 %. Then this strong year-class reached the commercial size, so the portion of commercial males increased to 66 % in 2014 and to 85 % in 2015–2016. The portion of juveniles was extremely small (3.1–6.5 %) in these years. The portion of commercial males had reduced again to 67 % in 2017 because of a new strong year-class appearance that provided the juveniles percentage increasing to 24.6 %. The mean size of commercial males has increased since 2012 in 18 mm and reached the value of 160.4 mm in 2017. Age of the crab males entry into the commercial cohort is estimated as 8 years. The observed cyclic changes in size composition of blue king crab and estimated value of its growth rate indicate indirectly a good and stable state of its population in the western Bering Sea.

Published: July 2019

Sickle cell disease is an autosomal dominant haemoglobinopathy in which an abnormal form of hemoglobin (hemoglobin S) polymerizes under low oxygen saturation and alters normal spherical shaped RBCs into sickle shape. In India, sickle cell disease is prevalent in central and southern states like Chhattisgarh, Madhya Pradesh, Orissa, Maharashtra, Jharkhand, Karnataka, Kerala, and Tamil Nadu. In various districts like Korba, Kanker, Rajnandgaon, Durg, Bilaspur, Raipur, Dantewada, Bastar, Mahasumund, Dhamtari, Kawardha and Jangjir-Champa of Chhattisgarh, frequency of sickle cell disease are approximately 10%. Screening results suggest that the prevalence of homozygous sickle cell disease was 2.1% and that of heterozygous sickle cell disease was 10% among different tribes. Prevalence rate among schedule tribe was 43.0%, schedule caste was 18.26% and 35.3% among OBC group with the majority of cases reported in Agharia, Kurmi, Teli and Panika castes. Common oral findings of dental hypoplasia, delayed eruption, mucosal pallor, and radiographic changes are noticed in this disease. This paper aims to describe etiology, prevelance of sickle cell disease in chhattisgarh region and the role of dental surgeon for the management of such patients.

Published: July 2019

Hub proteins participate in cellular regulation by dynamic binding of multiple proteins within interaction networks. The hub protein LC8 reversibly interacts with more than 100 partners through a flexible pocket at its dimer interface. To explore the diversity of the LC8 partner pool, we screened for LC8 binding partners using a proteomic phage display library composed of peptides from the human proteome, which had no bias toward a known LC8 motif. Of the identified hits, we validated binding of 29 peptides using isothermal titration calorimetry. Of the 29 peptides, 19 were entirely novel, and all had the canonical TQT motif anchor. A striking observation is that numerous peptides containing the TQT anchor do not bind LC8, indicating that residues outside of the anchor facilitate LC8 interactions. Using both LC8-binding and nonbinding peptides containing the motif anchor, we developed the “LC8Pred” algorithm that identifies critical residues flanking the anchor and parses random sequences to predict LC8-binding motifs with ∼78% accuracy. Our findings significantly expand the scope of the LC8 hub interactome.

Published: July 2019

This research was carried out to determine the
genetic distances and variability between some safflower landraces and
registered varieties. As plant material, four safflower landraces (TR 49119, TR
42630, TR 42670 and TR 64702) and three registered varieties (Yenice 5-38,
Remzibey 05 and Dinçer 5-118) obtained from the Aegean Agricultural Research
Institute, Turkey were used. The safflower varieties were analyzed at the
molecular level using RAPD markers. The polymorphic band ratios of ten RAPD
primers varied from 33.3% to (OPK-11) 80% (OPS-04). The average polymorphic band
ratio was found to be 63.9%. The polymorphism information content values of the
RAPD primers ranged from 0.24 for OPC-03 to 0.46 for OPA-19. The mean PIC value
was determined as 0.38. The mean resolution power value was found to be 3.37,
the effective multiplex ratio value was 4.14, and the marker index value was
1.57. The genetic distances were obtained using NTSYS-pc 2.20j statistic
package program according to Jaccard’s similarity coefficient. The genetic
similarity values of the safflower genotypes varied between 0.61 and 0.85. The
average similarity was calculated as 0.69. The cluster analyses of the RAPD
markers grouped the genotypes into two major clusters (UPGMA dendrogram). With
slight differences, the landraces and registered varieties were included in
separate groups. The TR 64702 line and Remzibey 05 registered variety were
genetically most similar genotypes with a value of 0.85.

Published: July 2019

In order to evaluate the effects of polyamines on
plant growth, physiological and biochemical characteristics of pepper seedlings
grown under salt stress (0, 50 and 100 mM NaCl), putrescine (Put), spermine
(Spr) and spermidine (Spd) were foliarly applied to the seedlings under
controlled greenhouse conditions. The effects of polyamines on plant height,
number of leaves, stem diameter, chlorophyll reading value (CRV), stoma
conductance (SC), tissue electrical conductivity (TEC), leaf relative water
content (LRWC), enzyme activity of superoxide dismutase (SOD), catalase (CAT)
and peroxidase (POD) of pepper seedlings were significant under salt stress. As
salt concentration increased, plant height, stem diameter, number of leaves,
CRV, plant and root fresh and dry weight, and LRWC lowered but an increase in
TEC occurred. However, polyamine treatments improved the parameters
investigated under salt stress. In the study, it has been determined that the
negative effects of salt stress can be mitigated with exogenously polyamine
applications to the pepper seedlings.
The Legacies of Manufacturing and Factories of Industrialised Construction
Authors: Couper Rachel , Maxwell Duncan , Aitchison Mathew
Published: July 2019

The term ‘industrialised construction’ carries the promise of an industry transformed, an industry driven by improved processes and higher quality products. One of the more obvious differences between industrialised construction and traditional construction is the factory. Yet it is often undervalued as a secondary consideration to the seemingly more important factors of speed, efficiency and economic rationalisation. This paper offers a reconsideration of the history of the factory as a critical feature in shaping contemporary sites of production in the construction industry. While the manufacturing mega-factories of today continue to develop at a rapid rate, their composition has been shaped by all three previous industrial revolutions and the current fourth. Drawing on the legacies of mechanisation, mass production and automation, today’s factory is informed by ideas of lean and agile production, and the connected factory forecast by Industry 4.0 looks towards the internet, cloud and IoT in visions of the future. By charting the evolution of the preceding three phases of industry in relation to key architectural developments of the factory, this paper reflects upon which aspects of these earlier chapters of manufacturing have affected the implementation of Industry 4.0 in the industrialised construction sector. Research in this area has often asked what the production sites of industrialised construction can learn from contemporary manufacturing, such as the automotive, aerospace or technology industries. By contrast, this paper questions the how the potential requirements of industrialised construction might differ from other forms of manufacturing and how this might in turn inform future sites of production in this sector. This paper speculates that a contemporary industrialised construction industry would be wise to re-evaluate the factory as a space specific to construction, distinct from manufacturing origins, in order to better address the broad range of new, or previously under-considered, industry specific requirements.
Transfer Learning Enabled Process Recognition for Module Installation of High-rise Modular Buildings
Authors: Zhang Zhiqian , Pan Wei , Zheng Zhen-Jie
Published: July 2019

High-rise modular buildings (HMB), based on the advanced approach of modular construction, have gained momentum in practice due to their offered benefits in accelerated construction, improved quality, reduced health and safety risks, and enhanced productivity. Modular construction with standard design of modules and repetitive processes of module installation is in favor of the development of construction automation. As module installation is one of the critical activities in the delivery of HMBs, it is important to recognize the module installation process automatically so as to facilitate automation in modular construction. However, there is no detailed phase-division of module installation process. Also, little research has been carried out on intelligent process recognition for module installation due to the limited amount of images of real-life projects. To fill in the knowledge gaps, this paper aims to build a transfer learning enabled process recognition model using convolutional neural network (CNN) for module installation of HMBs. The study first divided the module installation process into three stages: hooking, lifting and positioning, with a comprehensive literature review. Then the recognition model for module installation process was created and trained with the adoption of CNN-based transfer learning, and verified with images taken from real-life projects. The results show that the three stages of module installation process are effectively recognized with the proposed model. The transfer learning enabled image recognition model for module installation process accelerates automation in the construction of HMBs for enhanced productivity and accuracy.

Authors: Popovic Djordje , Thajudeen Shamnath , Vestin Alexander
Published: July 2019

Swedish house building companies currently face many challenges in terms of fluctuating market demand, need for flexible product offering, non-uniform governmental regulations, high costs, and long lead times. These challenges affect both internal and external efficiency of companies. Product platforms have been used for more than a decade in this industry to improve both internal and external efficiency. However, the industry is still criticized for its inefficient and costly process. Smart manufacturing has emerged as means to improve the efficiency of internal processes and the question is if and how smart manufacturing can complement and support product platforms in industrialized house building. The aim of this study is to explore the potential of smart manufacturing to complement and support product platforms in theory and practice in the context of industrialized house building. A literature review and a multiple case study were chosen to fulfill the study objective. In total fourteen semi-structured interviews were conducted in two timber house building companies. The data was analyzed within and across cases using four platform assets for categorization: components, processes, knowledge and relationships. The results show that the smart manufacturing technologies are in both theory and practice mainly supporting the process platform asset through developing vertical and horizontal IT systems integration, definition and digitalization of flexible building systems, and transferring explicit drafting and engineering knowledge into parametric modelling tools.

This paper focuses on a case study of a high-end cabinet manufacturer in Edmonton AB, Canada and the proposed process and facility improvements. First, computer simulation using Simphony.NET and movement analysis of people/materials of the cabinet manufacturer’s current state of operations is conducted to establish a baseline. Next, suggested process and facility layout improvements and their anticipated results are quantified through future state simulation in order to aid management in making decisions for plant changes and to prove their effectiveness. These improvements include: application of lean principles, modification of their current production methods to reduce bottlenecks, and future state facility layout based on an optimized flow of people and materials.

The market for modular buildings based on prefabricated room modules made of cross-laminated timber (CLT) is rapidly growing in Europe. Short construction times combined with high construction quality due to prefabrication are highly attractive features of this construction method. While structural design aspects have been steadily improved, only little attention has been paid to mechanical, electrical and plumbing (MEP) systems so far. However, the integration of water-bearing pipes and surface seals must be done with great care, since a permanent exposure of the timber construction to moisture caused by leaks may result in biological degradation of the wooden structure. The risk of moisture damage can be reduced by decreasing the length of horizontal piping by means of intelligent pipe routing. In addition, sensor technology can be used to detect water leaks in critical areas where other measures fail to provide sufficient protection. Both aspects are addressed in this paper. First, the results of an analysis of nine completed construction projects based on CLT modules including hotels, student residences, nursing homes, and health care centers are presented. The projects were used to identify the current state of practice regarding the design of CLT room modules with respect to the integration of MEP installations. In a next step, general strategies for a safe integration of MEP installations in timber buildings are outlined. A bathroom layout with optimized pipe routing based on three individual shafts is chosen to show the application of these strategies. The approach enables a considerable reduction of horizontal pipe length while maintaining the functional and architectural requirements of the room module. Finally, a new planar sensor for detecting water leaks is presented. The results were developed in the research project SensGT and will lead to standardized solutions for a safe integration of MEP installations in CLT room modules.

The integration includes managing materials during the front-end and the execution phases, managing the inventory, locating materials on site with Global Positioning System GPS, and developing Kanban systems for managing different stakeholders’ inputs onsite. The research also sheds the light into the effect of using RFID on leveraging valuable data. RFID systems can gather large amount of tag data via wireless connections.
Mass Timber in High-Rise Buildings: Modular Design and Construction; Permitting and Contracting Issues
Authors: Dorrah Dalia H. , El-Diraby Tamer E.
Published: July 2019

Due to the inherent inefficiencies in conventional approaches followed in the construction industry and the global demand for lean and sustainable construction techniques, modular construction has witnessed a resurge especially in high-rise buildings. As such, much efforts have been put in studying the use of mass timber for the main structure of high-rise buildings in order to ensure more sustainable developments with high levels of adaptability. In this regard, previous research efforts have primarily focused on the added benefits of mass timber, its structural design and performance, and associated safety requirements. However, owing to the novelty in combining modular processes with timber materials and associated lack of data, several regulatory barriers and contractual issues still exist. To mitigate these issues, this paper studies the specifics of permit approvals and contracting issues in timber high-rise modular buildings. The objective is to develop a comprehensive up-to-date review and analysis of the relevant practices and to conduct interviews with industry experts to analyze their concerns, given the insufficient number of guides and building codes that dealt with these issues. Hence, our study investigates the process of obtaining permit approvals from local jurisdictions in Ontario in addition to the requirements for submission of additional documentation, engineering analysis, and testing. Moreover, it analyzes the initial stage of contractual agreement of stakeholders under the uncertainties imposed on these buildings and evaluates the suitability of Integrated Project Delivery (IPD) contracting method. Presenting detailed analysis of the initial planning stages for timber high-rise modular buildings can in turn suggest the best practices to be taken into consideration for the successful implementation of these buildings under the current building code.
Developing an Analytical Solution that Mimics Simulation Modeling for Construction Planning: Earthwork Case
Authors: Shakeel Waleed , Lu Ming
Published: July 2019

Deriving a reliable earthwork job cost estimate entails analysis of the interaction of numerous variables defined in a highly complex and dynamic system. Using simulation to plan earthwork haul jobs delivers high accuracy in cost estimating. However, given practical limitations of time and expertise, simulation remains prohibitively expensive and rarely applied in the construction field. The development of a pragmatic tool for field applications that would mimic simulation-derived results while consuming less time was thus warranted. In this research, a spreadsheet based analytical tool was developed using data from industry benchmark databases (such as CAT Handbook and RSMeans). Based on a case study, the proposed methodology outperformed commonly used estimating methods and compared closely to the results obtained from simulation in controlled experiments.

Offsite construction methods have been promoted and recognized globally as advanced construction techniques. Panelization, a two-dimensional form of offsite construction has brought about many benefits including lower transportation requirements and design flexibilities. In North America, the panelized construction technique has become popular particularly for wood-frame wall panels for residential construction. However, although utilizing this advanced construction method can greatly improve the working environment and productivity, the conventional mentality in construction, which overlooks the value of an automated management system to support offsite prefabrication and onsite installation, hinders its potential. An automatic material estimation system can capture all computer-aided design (CAD) data from building information modeling (BIM) files automatically and convert them into enterprise resource planning (ERP) readable data so that the ERP system can be updated for the purpose of material estimation. With the assistance of a feature-based modeling method, the proposed automatic material estimation system can save huge amounts of manual work for quantity take-off and all required CAD data can be captured by the system in a few seconds. Although highly dynamic market demands result in continual changes in design, production plan, schedule, and inventory levels, the adoption of an automatic material estimation system could account for these dynamic changes in order to maximize production. Therefore, in this paper, an automatic material estimation system is proposed in order to enhance the design and estimation process in the manufacturing environment. The proposed system is introduced and the development of supportive software is described. The proposed system is implemented as a case study in a panelized construction manufacturing facility, ACQBUILT, Inc., based in Edmonton, Alberta, Canada.

Offsite construction has been widely used in the construction industry. The process improves productivity that leads to shortened project schedule and lower budget. Over the decades, offsite construction industry has continuously evolved with the aspects of management and technology. However, offsite construction companies still have various challenges such as accurately obtaining productivity metrics, which helps in production planning. These challenges result from lack of understanding the process itself because of high variation of wall panel design specifications along with high variability of cycle time at each work station. To solve the problem, productivity data needs to be collected in context to offsite construction. In this paper, a time study was conducted in one of Alberta’s-based offsite construction factory. From the collected data and product design specifications, multiple linear regression models were developed to represent the actual work station time. The comparison between actual collected duration and modeled duration for assembly station demonstrate its accuracy that ranges from 80 -99%. In the near future, findings will be used for simulation to forecast factory production and optimize the utilization of the resources.

Published: July 2019

This study is based on the following observation: there is a significant difference between the initial budget forecast and the final budget of construction project. Cost differences in construction projects between the first estimate made by the engagement committee and the actual construction cost at the end of the project are highlighted. Our study therefore focuses on indicators that track the overall cost of a construction project from the client's perspective, in this case the real estate development company. The objectives are as follow: Highlight cost variances in construction projects and analyze the gaps between the initial cost design by customer and final construction. The waste between the "design", “marketing” and "construction" phases is discussed. The paper also quantifies waste in terms of cost between the phases. The analysis reveal that the overall cost evolution is 2.59%, with 0.89% coming from the Construction phase and 1.72% from the Marketing phase, and 0.09% from the Design phase. The results could be of interest to a wide range of researchers working on the interface between the design and construction phases.

In order to expedite market acceptance and facilitate the commercial uptake of wood products and systems in Canada, it is necessary to showcase such applications through high-rise and non-residential building demonstration projects. This paper presents recent initiatives by the Government of Canada focused on increasing use of wood as a green building material in infrastructure projects by supporting such demonstration projects. The objective of Green Construction through Wood (GCWood) program (launched in 2017) is to support the design and construction of several high-rise and non-residential timber demonstration buildings and bridges in Canada through expression of interest (EOI) calls. The program is also supporting research and development activities to facilitate acceptance of provisions that would allow for the construction of tall wood buildings in Canadian building codes and advanced wood education at engineering and architectural colleges and universities to help develop the future design capacity in Canada.
