Since 2016 Myanmar has undergone political and economic reforms. A movement to develop the country with economic growth is a significant matter for the country. In Myanmar, the construction sector is a main driving force for the country’s economy in terms of investments and job opportunities of citizens. Electricity used for the construction industry leads to the insufficient energy output of the country. Moreover, waste and pollution are inevitable as a result of Myanmar’s economic growth. Green building development in Myanmar is in its initial stage but currently lacks governmental, or voluntary support to devise appropriate rules and regulations for green construction. In particular, the lack of awareness among developers, stakeholders, architects, engineers, contractors, employees and the public about green building has worsened the development progress. This paper reveals why green building development is needed in Myanmar and provides an overview of the current level of green growth in Myanmar. In addition, this paper compares widely used seven existing environmental assessment tools around the world – LEED, BREEAM, Green Mark, Green Star, Three Star – Chinese Green Building Label-3, CASBEE, and HQE as references for the development of green building rating tool with the view to identify aspects that are compatible with the local conditions of Myanmar.

     Suicide attacks, bombings, explosions became the part of daily life in Iraq. Consequently, the threat of terrorism put the Iraqi construction sector in the face of unique and unusual challenges that not seen on other countries. These challenges can have extensive impact on construction projects. This paper seeks to examine the impact of the terrorist attacks on construction industry and determine the extent to which the impact of terrorism on construction projects in terms of cost, schedule, and quality. This study adapted quantitative and qualitative approaches to collect data using questionnaire survey and interviews, as well as historical data. The study focused on projects that have been the target of terrorist strikes in Diyala governorate. A variety of statistical procedures were employed in data analysis. The results revealed the extent to which terrorist attacks impact construction projects in terms of cost, time, and quality. The results of this study will enhance the awareness of all construction parties to the impact of the terrorist attacks against construction projects. Eventually, this can develop a risk management assessment and assist contractors to properly protect projects and buildings to minimize injuries and fatalities in the event of terrorism.

Криминалистическая характеристика хищений в сфере строительства представляет собой систематизированное описание криминалистически значимых признаков данной группы преступлений (хищения, совершенного путем мошенничества, а также хищения, совершенного путем присвоения или растраты). Криминалистическая характеристика хищения в строительстве должна состоять из криминалистически значимых элементов, описывающих данную группу преступлений и позволяющих следователю, опираясь на нее, осуществить качественное расследование. Знание следователем содержания криминалистической характеристики конкретного вида или группы преступлений и ее практическое использование позволяют ему в условиях дефицита информации на первоначальном этапе расследования минимизировать риск принятия неверных решений и совершения ошибочных действий. Элементами криминалистической характеристики хищений в строительной сфере являются: 1) сведения о способе хищения в строительстве (включающие в себя сведения о способах подготовки, совершения и сокрытия преступления); 2) сведения о характерных типичных следах (материальных и идеальных) совершенного или совершаемого хищения в строительстве. Знание содержания именно этих элементов следователем на первоначальном этапе расследования хищений в строительной сфере обеспечат верный выбор направления расследования и оперативное проведение следственных действий по обнаружению и изъятию доказательств, сведя к минимуму их возможную утрату. Criminalistic characteristics of theft in the construction sector is a systematic description of criminally significant features of this group of crimes (theft committed by fraud, as well as theft committed by appropriation or embezzlement). Criminalistic characteristics of theft in construction sector should consist of criminally significant elements that describe this group of crimes and allow the investigator, based on it, to carry out a qualitative investigation. The investigator's knowledge of the content of the forensic characteristics of a particular type or group of crimes and its practical use allow him to minimize the risk of making incorrect decisions and committing erroneous actions in the context of a lack of information at the initial stage of the investigation. The elements of criminalistic characteristics of theft in the construction sector are: 1) information about the method of theft in construction (including information about the methods of preparation, Commission and concealment of the crime); 2) information about the characteristic typical traces (material and ideal) of theft committed or committed in construction. Knowledge of the content of these elements by the investigator at the initial stage of the investigation of theft in the construction sector will ensure the correct choice of the direction of investigation and prompt conduct of investigative actions to detect and remove evidence, minimizing their possible loss.

The Impact

Total factor productivity (TFP) is of critical importance to the sustainable development of construction industry. This paper presents an analysis on the impact of migrant workers on TFP in Chinese construction sector. Interestingly, Solow Residual Approach is applied to conduct the analysis through comparing two scenarios, namely the scenario without considering migrant workers (Scenario A) and the scenario with including migrant workers (Scenario B). The data are collected from the China Statistical Yearbook on Construction and Chinese Annual Report on Migrant Workers for the period of 2008–2015. The results indicate that migrant workers have a significant impact on TFP, during the surveyed period they improved TFP by 10.42% in total and promoted the annual average TFP growth by 0.96%. Hence, it can be seen that the impact of migrant workers on TFP is very significant, whilst the main reason for such impact is believed to be the improvement of migrant workers’ quality obtained mainly throughout learning by doing.

The properties and the behaviour of plaster mortars designed with Polyurethane Foam Waste (PFW) are studied in this investigation. A characterization of the mixtures is completed, in accordance with the technical specifications of European Norms. The incorporation of polyurethane waste foam can yield porous and lighter mortars, with better resistance to water-vapour permeability, although with weaker mechanical strength and higher levels of absorbency. Nevertheless, suitable mechanical strengths were achieved, resulting in a new material that is compliant with the requirements of the construction industry. The use of PFW in the the manufacture of gypsum mortars for construction reduces the consumption of natural resources and, at the same time, recovers an industrial waste that is otherwise difficult to recycle.

ABSTRACTThe growth and chemical intermixing of submonolayer and a few monolayer thick Fe films on a Au(001) surface was studied by High Resolution Low Energy Electron Diffraction (HRLEED) technique. Through the analysis of the energy dependent angular profiles as a function of time, we obtained the distribution of islands and distribution of spacings during submonolayer growth. The interference of electron waves from different chemical elements in terraces at different heights in the surface contributes to the background intensity and broadening in the angular profiles of diffraction beams. A subsurface Fe capped by Au islands as a result of atomic place exchange was observed at the initial stage of monolayer growth. From the energy dependent angular profiles as a function of temperature, we determine the quantitative change of inhomogeneity length (∼20 Å) at the interface of ultrathin films at elevated temperatures due to intermixing.

This work evaluated the influence of additions of the ceramic shell residue (CSR), from the industries of Lost Wax Casting, in the modulus of elasticity and porosity of concrete. The CSR was ground and underwent a physical, chemical, and microstructural characterization. It was also analyzed, the environmental risk of the residue. In the physical characterization of the residue were analyzed, the surface area, and particle size distribution. In chemical characterization, the material powder was subjected to testing of X-ray fluorescence (XRF). Microstructural characterization was performed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The residue was utilized like addition by substitution of cement in concrete in the percentages of 10% and 15% by weight of Portland cement. It was evaluated properties of concrete in the fresh and hardened state, such as compressive strength, modulus of elasticity, absorption of water by total immersion and by capillarity. The results showed that the residue can be used in cement matrix and improve some properties of concrete. Thus, the CSR may contribute to improved sustainability and benefit the construction industry.
