Published: May 2020

Nitel araştırma
türlerinden durum çalışması olan bu araştırmanın amacı TÜBİTAK tarafından
desteklenen 4005 projesi kapsamında bir hafta süren Fen, Teknoloji, Mühendislik
ve Matematik (FeTeMM) hizmet içi öğretmen eğitimi programı sırasında eğitime
katılan öğretmenlerin FeTeMM eğitimine ve bileşenlerine dair zihinsel modellerindeki
değişimin incelenmesidir. Çalışmada 12 erkek ve 12 kadın olmak üzere toplam 24
kimya öğretmeninin eğitim öncesi ve sonrası FeTeMM eğitimine ve bileşenlerine
dair zihinsel modelleri Ring, Dare, Crotty ve Roehrig  (2017) tarafından geliştirilen ve
araştırmacılar tarafında Türkçe’ ye çevrilen FeTeMM’ e ilişkin Zihinsel Model
Protokolü uygulanarak incelenmiştir. Protokolde öğretmenlerden hem bir şekil
çizmeleri hem de bu şekli açıklamaları istenmektedir. Çalışmadan elde edilen
veriler hem tümevarım hem de tümdengelim yöntemi birlikte kullanılarak analiz
edilmiştir. Analiz süreci tamamlandıktan sonra öğretmenlerin ilk ve son FeTeMM
modellerinde bir değişim olup olmadığını anlamak için sürekli karşılaştırmalı
analiz metodu kullanılmıştır. Eğitim öncesi Bütünleşik FeTeMM eğitimi
hakkındaki çizimler ve açıklamalar daha çok FeTeMM disiplinleri arasındaki
ilişkiyi göstermiştir. Ancak mühendislik tasarım süreci ve günlük hayat
problemleri çok az katılımcı tarafından değinilmiştir. Ayrıca ilk çizimler
genel olarak değerlendirildiğinde daha az detay içerdikleri ve katılımcıların
tam olarak düşündüklerini çizerek ifade etmekte zorlandıkları görülmektedir.
Projede verilen eğitimlerden sonra yapılan uygulamada ise katılımcıların
Bütünleşik FeTeMM öğretimine yönelik modellerinde ciddi değişimler olduğu
görülmektedir. Örneğin, proje öncesi çizimlerde FeTeMM modellerinde grup çalışması,
iletişim ve FeTeMM+ kavramları bulunmazken, proje sonrası çizimlerde bu
kavramlar yer almıştır. Buradan hareketle, öğretmenlerin zihinlerindeki
modellerin sınıflarındaki FeTeMM uygulamalarındaki önemli rolü düşünüldüğünde, öğretmenlerin
FeTeMM’ e yönelik algılarının incelenmesi ve mevcut algıların alan yazın
tarafından vurgulanan özelliklere sahip algılar ile değiştirilmesi
gerekmektedir.

Practical Implementation of Contract Administration Performance Model in Qatar Construction Projects
Authors: Gunduz Murat , Elsherbeny Hesham A.
Published: May 2020

Globally, the performance of Construction Contract Administration (CCA) is becoming of significant interest as the industry suffers from notable delays, cost overruns, and disputes as a consequence of poor contract administration practices. In Qatar, the pace of projects will continue after hosting the FIFA 2022 World Cup to achieve the 2030 Qatar National Vision and beyond, therefore, monitoring of the proper CCA implementation and performance is necessary. Due to the wide scope and complicated nature of CCA, there is yet no consensus on how to assess its performance. This study briefly presents a systematic, operational, and multi-dimensional construction Contract Administration Performance Framework (CAPF) consisting of 93 CCA key measures/ tasks categorized in 11 CCA dimensions/process groups. The proposed framework is validated by structural equation modeling and subsequently, the Contract Administration Performance Model (CAPM) model was established. Through this study, the CAPM and its components are briefly explained, and then implemented on a real-world sample of 13 small, medium, and major construction projects in Qatar covering both public and private sectors, and then the performance is benchmarked. It is found that the model provides an operational basis for measuring the CCA Group Performance Indices (GPI), the overall Construction Contract Administration Performance Index (CCAPI) and support the identification of underperforming groups. The benchmarking value for the CCAPI (77.5%) demonstrates that the level of CCA performance is good. Also, the benchmarking values of GPI (range 74.3% to 87.8%) are good, except risk management (GPI= 50.5%), which needs an improvement program.

Authors: Nosheen Asia , Arewa Andrew Oyen , Akhtar Hafiz Muhammad
Published: May 2020

Globally, claims and disputes are an unfortunate reality in construction projects. Recent statistics reveal that construction claims in the UK increased by 21% in 2018 compared to other countries such as India (8%), Mexico (3%), Ireland (2%), and Cyprus (2%). Though, construction industry is known for array of standard forms of contract and administrative tendencies; unsubstantiated claims and chronic disputes remain prevalent in the sector. Yet, there is little research on preventive approach to unsubstantiated claims that ultimately lead to disputes. The study advocates the use of Systematic and Technical Appraisal (STA) to prevent unsubstantiated claims and disputes in the construction industry. The study research method is based on qualitative research technique and use of case studies. The research question is: does systematic and technical appraisal of construction claims help prevent unsubstantiated claims and disputes in the UK construction industry? The study population sample is drawn from experienced industry stakeholders including clients, contractors, consultants, experienced quantity surveyors and cost managers in addition to use of construction case studies. Initial findings reveal that claim management processes in the construction sector are far-off from perfection. Other findings reveal that robust systematic and technical claim appraisal process has potential to prevent unsubstantiated claims; which in most cases lead to disputes. The study is part of an on-going PhD study to seek to develop an effective claim management system for the UK construction industry.
Project Management: Key Initiatives Case Study
Authors: Al Nass Khaled , Melilla Lavinia , Tolba Mohamed
Published: May 2020

Every project faces risk of delays and disruptions, especially the mega/complex projects of today, which have, amongst others, many interfacing parties engaged. Local roads and drainage projects in general, including DN016, can be considered complex projects due to a number of reasons such as, a) working in residential areas, b) deep excavations, c) number of interfacing parties, d) project duration, e) multifaceted identification for the location of existing underground utilities. The contractor decided to use some tools to help minimize the negative impacts of a number of challenges such as, 1) workface planning by dividing the project into 5 zones and start working in free zones for early zone handover, 2) lean construction to minimize the waste, 3) management processes in order to control the known-unknown challenges and risks and to minimize those and 4) Building Information Model (BIM) for the identification of major and minor clashes to the designer in order to resolve them early as to have a smooth construction flow. In addition, the project management team identified both internal and external stakeholders of the project in order to determine the project requirements and expectations of all parties involved. A dedicated stakeholder manager was appointed to identify and manage the stakeholder issues without affecting the project performance. Although major efforts are done in this regard, many stakeholders residing nearby the construction area are negatively affected from the project execution due to the nature of the project and time constraints. The supervision consultant and the client also directly engaged in managing the stakeholders and ultimately impacted the project. However, further delays were mitigated with the implementation of regular stakeholders’ meetings, and work was carried over based on their requirements. Also, the project management decided to have a handing over plan from early stages of the project and to assign a dedicated handing over manager with required resources, and mobilize them very early in the project. The handing over team identified all the handing over procedures and the required documentation with the client.

Authors: Abdi Ali Mohamed , Arewa Andrew , Tyrer Mark , Ugulu Rex Asibuodu
Published: May 2020

One of the main objective of the building design is to provide comfort and safety to occupants, particularly during adverse weather conditions. In most part of the world, people stay indoors during adverse weather conditions, thus increasing energy consumption. In UK, vulnerable people such as the elderly are highly affected with mortality rate during extreme weather conditions. The 2003 heatwave reached average of 38.5° C in the UK resulting in the death toll of 2,234. The 10 days period of extreme heat is thought to be the warmest about the last 500 years. Across Europe, the 2003 heatwave resulted in 20,000 deaths; in France alone, the number reached 15,000. Similarly, the 2018 summer heatwaves, reached 35.5°C contributing to 863 deaths. Yet, there is little research regarding impact of energy efficiency in building and deaths caused by excessive heatwaves in the UK. The study aims to investigate the impact of energy efficiency in buildings and excessive heatwave deaths among elderly people in the UK. Research question asked is; do energy efficiency programmes and policies contribute to excessive summer deaths in the UK? .The study adopted quantitative research method with participants drawn from low/average income households, in west midlands part of UK, between 2003/04 to 2017/18. Initial findings show that there is a significant relationship between energy efficiency adoption, government policies and excessive summer deaths.
Effective Project Control within the Context of Lean Construction
Authors: Koluksuz Andre F.
Published: May 2020

Two of the “Lean Thinking” principles relate to managing a project through relationships, shared knowledge and common goals and to removing waste where possible. Success of a project is only possible with the collaboration of all project participants and stakeholders throughout the entire project life cycle. Collaboration starting at the early stages of the project enables the project participants not only deliver what the owner wants, but also allows them to provide advice and help shape expectations throughout the project. In the age of technology, too much unfiltered data and information are produced quickly, making it a challenge to determine what is significant and what is not. As Project Controls is an important element of “Lean Construction” philosophy, it should be subjected to similar scrutiny to explore opportunities for improvement and for minimizing the waste. This paper will discuss how utilizing both the old and new ideas and methodologies such as the Critical Path Method (CPM), Pareto Principle and Last Planner System® (LPS) will help project managers adopt a balanced approach in selecting the optimal processes, methodologies and tools for meaningful project planning, progress monitoring and communicating the right amount of information on a timely basis.

Authors: Setawati Evi , Azam Muchammad , Ketut Umiati Ngurah Ayu , Oktajianto Hammam
Published: May 2020

The Linear particle accelerator (LINAC) is a tool for radiation therapy that can emit photons and electrons. Radiation of X-ray photons and LINAC electrons is obtained from the interaction of electrons fired into the target plate (tungsten). This radiation can not only affect the target organ but can also affect unwanted organs around the exposure area. Radiation irradiation effects on the organs in the exposure area can be known through simulation of LINAC and phantom radiation processes. Simulation and calculation using Monte Carlo method. This program is operated by MCNPX software. Phantom geometry uses the phantom ORNL MIRD, whereas linac geometry consists of linac blankets, tungsten plates and collimators. Radiation from linac is directed to the left lung as a target and from the simulation results of traces of radical particles shows that radiation emission from linac there are some scattering, but scattering this does not have a significant impact because the amount is not too large. Radiation effect on the organs is indicated by the effective dose quantities in which the left lung has a greater effective dose than the surrounding organs. While the right lung gets a large enough effect from other organs around the target organ. This is because the organ is located close to the target organ and has a smaller type of meeting of the other organs. Not so with the ribs, although it is the first organ exposed to radiation. Radiation that concerns the ribs has no significant effect. This is because of the enormous type of meeting. The effects of radiation on organs are not only influenced by the size of the meeting of organ types but also influenced by the weight factor.

Published: May 2020

The Construction Industry, which was badly hit by the demonetisation, is getting back to normalcy with construction activities coming up in full swing. Chennai City and its outskirts are buzzed with building work from small apartments to tall towers. Next to agriculture, construction industry is the source of employment for a large number of people, mostly uneducated. The piquant situation is that in some parts of the state the activities have come to a “slow going” due to paucity of river sand and whereas in the City and its outskirts, the work is going on uninterrupted. While the small builders are worst hit by the non-availability of river sand, the big builders manage the activities. The reason is that they have rate contract with two to three large suppliers for sand. Moreover, they are also using M Sand in the construction activities.

Published: May 2020

Multi-Criteria Decision Making is one of the most important issues, especially when there are numerous competing criteria and alternatives to consider. There are a variety of approaches for dealing with such issues. The Analytic Hierarchy Process (AHP) is one of the most popular problem solvers for this type of problem, and it's especially useful for determining the weights of the criteria. Using decision-makers' evaluation tables, this method compares each of the criteria to each other. Furthermore, this method employs a consistency ratio to assess the consistency of decision-makers' choices. The decision maker's experience and knowledge are critical in this process. Selection of a construction vehicle (truck) alternative is discussed in this study. Four different vehicles are selected based on five criteria. The AHP approach is used to choose the best option. The results are interpreted at the end of the process.

In this examination we have proposed Learning invariant shading highlights for individual recognizable proof utilizing human face for high proficient flag exchange framework applications. In this paper, we have a tendency to propose an information driven approach for taking in shading designs from pixels examined from pictures crosswise over to camera sees. The instinct behind this work is that, even assuming picture element values of same colour would wander across views, they thought to be encoded with indistinguishable qualities. We tend to model colour feature age as a learning drawback by together learning a direct transformation and a wordbook to write in code picture component esteems. We have a tendency to conjointly dissect entirely unexpected estimating invariant shading zones. Abuse shading in light of the fact that the exclusively prompt, we tend to contrast our approach and all the estimating invariant shading zones and show better execution over every one of them. Overwhelming pivoted nearby double example is anticipated yields higher execution. This paper proposes a totally exceptional strategy of characterizing the outer body part misuse Convolutional Neural Network.

Authors: Papaioannou Evi , Vardakis Angelos , Kaklamanis Christos
Published: May 2020

We present oPESA, an online examination management system for exam-hall seating arrangement. oPESA is a platform built on PHP, HTML, CSS, JavaScript, jQuery and SQL. It is an open platform which can be accessed only by registered users, i.e., professors and students. Professors provide as input course details like title, examination date and room; additional input, like predetermined lists of students or list of constraints regarding the seating plan, can also be given. Students simply register for course examinations by providing their student ID as input. Whenever a student registers for an examination, oPESA immediately responds by automatically assigning an exam-hall seat to the student. Seat assignment is performed by an unbiased algorithm ensuring randomness and fairness. Results appear online but can also be downloaded and saved locally in .xls format. oPESA follows a responsive web design which allows it to automatically resize, hide, shrink or enlarge in order to look good on all devices (desktop computers, tablets, smartphones). oPESA suggests a very useful management tool for modern - highly-populated - higher education institutes which significantly facilitates the examination management process offering clarity and efficiency.

A pilot external-loop airlift reactor (ELAR) of 150 liters was designed and used as a non – conventional reactor to carry out Electrocoagulation/Electroflotation to treat real textile effluents containing disperse and reactive dyes. The designed reactor ensure the recovery of sludge by electroflotation (EF) in which complete flotation of the pollutants is achieved without additional mechanical power in the pilot external-loop airlift reactor (ELAR), using only the overall liquid recirculation induced by H2microbubbles generated by water electrolysis without filtration process. Aluminum, iron electrodes and combined aluminum – iron electrodes were tested. The obtained results were interesting as they would help managing the Electrocoagulation/Electroflotation process in pilot external – loop airlift reactor to remove real textile effluent. The treatment of the mixtures of the real textile dyeing industry is better when using a combination of the electrodes of iron and aluminum providing a better treatment efficiency of 80% and a lower specific energy consumption (50 kWh/kg dye). In order to analyze the by-product of the electrocoagulation (EC) and the treated effluent, different techniques were used to elucidate the role of different kind of anodes especially when the combined iron – aluminum were used simultaneously as sacrificial anodes.

Authors: Gagné Cynthia , Clairoux Natalie
Published: May 2020

Introduction : Cet article vise à décrire l’évolution du programme de formation documentaire de la Bibliothèque X de l’Université X par rapport à ce qui a été décrit pour 2011-2012 par « auteur » et coll. [1]. Les formations seront analysées individuellement afin d’évaluer à quel point chacun des fondements du Référentiel de compétences informationnelles en enseignement supérieur de l’ACRL est abordé et d’identifier d’éventuelles lacunes dans sa couverture.
Description : Cinq nouvelles formations intégrées aux cursus et deux nouvelles formations libres ont été mises en place. Plusieurs modifications ont été apportées aux formations existantes. Entre autres, l’évaluation des apprentissages se fait maintenant presque totalement en ligne et est plus souvent liée aux travaux de session des étudiants.
Résultats : En 2018-2019, le programme comprenait 172 activités totalisant 304 heures et rejoignant 6 651 participants. La formation virtuelle (guides, tutoriels et capsules) est plus développée qu’auparavant. Les fondements 1 (L’autorité est contextuelle) et 5 (La production de savoirs résulte d’échanges) du Référentiel sont les moins abordés. Le fondement 6 (La recherche d’information est une exploration stratégique) est le plus couvert.
Exposé : Le programme de formation documentaire est plus intégré aux cursus qu’en 2011-2012, mais une évaluation formelle des apprentissages à long terme et le renforcement des notions apprises lors de plusieurs séances étalées dans le temps sont à envisager. Davantage de formations pourraient être offertes aux étudiants des cycles supérieurs, qui sont particulièrement touchés par les fondements 4 (La recherche savante est une démarche d’investigation) et 5 (La production de savoirs résulte d’échanges).

Published: May 2020

A series of on-farm fi eld experiments were conducted in two locations in Padang, Koto Panjang and Koto Tingga, West Sumatera, Indonesia in 2015. The purpose of the experiment was to establish the formula of organic fertilizer derived from Tithonia supplied with micro nutrients, Zn and Mn, on rice. The experiments were conducted using completely-randomized block design with six treatments and three replications. The treatments were P = Tithonia Organic Fertilizer Plus (TOFP) + 3.0 kg Mn.ha-1, Q = TOFP + 3.0 kg Mn.ha-1+ 3.0 kg Zn.ha-1, R = TOFP + 4.5 kg Mn.ha-1 + 6 kg Zn.ha-1, S= TOFP + 4.5 kg Mn.ha-1+ 9 kg Zn.ha-1, T = TOFP only, U = 100% chemical fertilizer only. Treatment with micro nutrients as addition to TOFP (TOFP+ 3.0 kg Mn.ha-1 and TOFP+ 3.0 kg Mn.ha-1+3.0 kg Zn.ha-1) increased rice grain yield by 80 g per clump.

Patchouli (Pogostemon cablin Benth.; 2n = 32) is an aromatic herbaceous plant commonly cultivated for use in the the fragrance industry. As patchouli is propagated by cuttings polyploidization induction by colchicine treatment was conducted to obtain a new genotype with high patchouli alcohol content. This research aimed to increase patchouli genetic diversity with colchicine treatment by the formation of a polyploid plant. Axillary buds from single node cutting of aseptic plantlets were used as the explants. The experiment was arranged using a factorial completely randomized design with two factors, namely the concentration of colchicine and the immersion duration. Genetic diversity of patchouli was successfully enhanced by adjusting the colchicine concentration and immersion treatment. lethal concentration (LC) of 50% in patchouli was 0.132% and the LC 50% for soaking time was 60.16 hours. The number of chloroplasts, stomatal length and chromosome number increased with increasing ploidy, whereas stomatal density and the number of trichomes decreased. The chromosome number of 16 patchouli mutants in generation 4 was still unstable, and a chimera was found with mixoploidy between 20-80. A hierarchical dendogram clustered 16 patchouli mutants into four different groups.

Published: May 2020

The typical metal transfer mode in conventional underwater wet flux cored arc welding (FCAW) delivers large droplet repulsive transfer with low frequency. The process stability and the weld quality are seriously deteriorated with significant spatter and frequent arc extinctions. It is thought the repulsive forces applied on droplets can be reduced by rapidly decreasing the welding current, making the droplets sag and oscillate. A novel underwater pulsecurrent FCAW was proposed to periodically regulate the forces applied on droplets. The experimental system was developed with specially designed pulse current and reliable arc length control. Visual and electrical signals were collected simultaneously to study the process features. It was found that the maximum droplet diameter decreased to less than 5 mm; the temporary arc-extinguishing frequency decreased significantly; there was almost no short-circuit transfer and surface-tension transfer; and the stability of the welding process was significantly improved.
