Informal settlements in cities require wider and more comprehensive planning. Lack of attention toward inequalities in the entire city and to the conditions of accommodation in informal settlements has caused unsustainability in these settlements. Accordingly, for the purpose of identifying indicators of urban unsustainability in informal settlements in Iran and planning for the improvement of these indicators, this paper first studied the sustainability indicators of urban informal settlements in Sanandaj and then analyzed the sustainability of these settlements using SWOT. According to the results, the informal settlements in Iran were unsustainable in terms of such indicators as employment, housing, housing cooperative companies, participation in projects, promotion of local culture, public services, transportation, environmental attributes, health services, etc. Planning for the sustainability of these settlements should focus on aspects such as renewable energy, housing, economic planning, urban spaces, land management, upgrading plans, employment and transportation planning. © 2016, Springer Science+Business Media Dordrecht.

Increasing housing demand and the precious value of city land have caused to the construction of multi-storey, deep-plan and compact buildings. Architectural design needs to provide the appropriate penetration of daylight and ventilation into the deep-plan buildings. Therefore further researches are necessary in the field of natural lighting and ventilation systems. Light-well is an architectural daylight system to deep-plan building which is widely used in the residential buildings of the case study of this research (Tehran, Iran). In this study, effective factors in daylight performance of light-wells are investigated with dynamic daylight metrics. In this research, the continuous daylight autonomy (DAcon) is utilized for evaluating of annual illuminance for attached rooms to light-well. The main goal of this research is to estimate the effect of some affecting variables on the daylighting performance of light-wells (the area and horizontal section form, the optimal height of the light-well, orientation variation and the slope of light-well surrounding wall) to provide suggestions for better utilization of light-wells in residential building. 352 computer simulations using Daysim software have been conducted to assess the expressed variables. Also, Autodesk Ecotect software has been used as graphical user interfaces for Daysim. The findings of this study show the better daylighting performance of cylindrical light-wells compared with the common square light-well in Tehran. Also, the optimal height of different types of light-wells in residential buildings has been suggested with regards to the adequate daylight autonomy (DA) in connected rooms to light-well. The results of this study show that the increasing of the suggested optimal height for different types of light-wells is possible with increasing the slop of walls of light-wells and the window size in the lower floors. © 2017 Elsevier Ltd

Archaeological excavations in western Iran have recently revealed a significant Luristan Bronzes collection from Sangtarashan archaeological site. The site and its bronze collection are dated to Iron Age II/III of western Iran (10th-7th century BC) according to archaeological research. Alloy composition, microstructure and manufacturing technique of some sheet metal vessels are determined to reveal metallurgical processes in western Iran in the first millennium BC. Experimental analyses were carried out using Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy and Optical Microscopy/Metallography methods. The results allowed reconstructing the manufacturing process of bronze vessels in Luristan. It proved that the samples have been manufactured with a binary copper-tin alloy with a variable tin content that may relates to the application of an uncontrolled procedure to make bronze alloy (e.g. co-smelting or cementation). The presence of elongated copper sulphide inclusions showed probable use of copper sulphide ores for metal production and smelting. Based on metallographic studies, a cycle of cold working and annealing was used to shape the bronze vessels. © 2014 Elsevier Inc.

There is no dispute over the importance of sustainability. We know already that our cities, the containers of our behaviors, have to use resources considerately in respect with their ecology. Yet, as our behaviors' technological context advances, we have taken successive step away from our sustainable design solutions. Eventually we are going through over-decades-accumulated consequences of our nature-striking industrial and consumption technics. Moreover, studied climate changes projects an unacceptable outlook of future unless we modify our today technology consumption in the first step, and direct our technics toward procedures that has each ecosystem energy pathways at the root, literally toward sustainability. In this study we seek if presumably there exist threads of sustainable methods we used in past (e.g. organic production methods that has closer forms to natural ecosystems). As the ultimate goal we aim to develop them to scales or intensities that responds to today world's rates leading to take a step ahead in modern responsive urban design solutions. Traditional context of Bushehr a city located in the south of Iran is a case study with significant advantages, one due to using traditional solutions to wide range of severe climate conditions and the other, it has an extremely unexploited traditional pattern as the date study performed. This study derives the common patterns of Bushehr's urban design from the large-scale to the small-scale, and proceeds to analysis and evaluation of these patterns. Reviewing the traditional patterns gives us a benevolent handbook of experimented solutions used in the past. Also there is a gradually emerging need for primitive or iconic design objects to represent originality of the context. Here there are problems of this subjected discussed in the study. © 2015 The Authors. Published by Elsevier Ltd.

A number of steel plaques in Iran belong to Safavid period (17th century) were examined for their chemical composition and microstructure. The artefacts were analyzed using micro-PIXE, SEM-EDS and reflected light microscopy (OM). According to SEM-EDS and micro-PIXE analyses, it was revealed that the plaques were made of mostly pure iron (approximately 99 wt%). Presence of trace amounts of manganese, sulfur, chromium, silicon, titanium and potassium were identified in the plaques. Metallographic investigation showed that the plaques were made of hypereutectoid steel with a microstructure consisting of spherical particles of carbide in the ferrite and pearlite background. Moreover, the use of ultra-high carbon (UHC) steel with microstructure of pearlite matrix and needle-like Widmanstätten cementite was identified in one plaque. These features showed that Safavid plaques have been made of crucible steel. In addition, it demonstrated that complicated forging/heating cycles have been used for manufacturing of these openwork steel plaques. It was also revealed that in addition to arms and armors, crucible steel has served as an everyday work material in Safavid period in Iran. © 2016 Elsevier Inc.

Cyclic voltammetry and differential pulse voltammetry were used to investigate the electrochemical behavior of ascorbic acid (AA) on palladium coated nanoporous gold film (PdNPGF) electrode. The deposition of palladium was done through oxidation of copper UPD layer by palladium ions. This low Pd-loading electrode behaved as the nanostructured Pd for electrocatalytic reaction. The PdNPGF electrode exhibits excellent electrocatalytic behavior by enhancing the AA oxidation peak current due to synergistic influence of the Pd film and NPGF. The kinetic parameters such as electron transfer coefficient, α, was 0.47 and the voltammetric responses of the PdNPGF electrode were linear against concentration of AA in the ranges of 2.50-33.75mM and 0.10-0.50mM with CV and DPV respectively. © 2012 WILEY-VCH Verlag GmbH & Co.

An outstanding style of Persian tilework, which emerged from the north-eastern Iran in the 15th century, was extensively used for decorating architectural facades during the Safavid period (from the 16th through the 18th century). This type of tilework, the so-called haft rang, technically comprises of forming a clay body and firing two glazed layers on top of the body. In the present paper, the first analytical data concerning haft rang tiles is provided. To do so, forty three samples of Safavid haft rang bodies were analysed by wavelength dispersive x-ray fluorescence (WDXRF) and the obtained data were handled by principal component analysis (PCA). The results showed that the 17th century haft rang tiles wherever found are local products; that is, Safavid tile-makers have used local clay sources to make the bodies of haft rang tiles. The analytical data also showed that old tileworks, in general sense, can be simply replaced by newly manufactured tiles or, at least, all tilework revetments in an individual edifice might not have been produced in an identical workshop. Moreover, WDXRF was used as an accurate and precise method to determine the chemical composition and to support compositional classification in provenance studies and can be considered as a reliable alternative for studying the provenance of archaeological ceramics. © 2013 John Wiley & Sons, Ltd.

The pigments used in the wall paintings of the Masjid-i Jame of Abarqu, central Iran, as less-known pigments used in the history of Persian painting, were investigated with micro-Raman spectroscopy, micro X-ray fluorescence (micro-XRF), scanning electron microscopy (SEM), and polarised light microscopy (PLM). The results showed that the green, red, and blue pigments were atacamite, red lead, and smalt mixed with natural ultramarine blue respectively applied on a white substrate composed of white huntite. Moreover, the blue smalt was identified to be used on the white huntite and under the paint layer in order to delineate the design of the wall paintings and to act as a rough sketch for the subsequent use of the other pigments. Glushinskite, as a less-reported mineral in historical wall paintings, was identified by micro-Raman spectroscopy and hypothesised to be associated with the degradation of the white huntite binder. Furthermore, micro-Raman spectroscopy studies surprisingly revealed the mineral woodhouseite sparely mixed with the green pigment. This paper strongly suggests micro-Raman spectroscopy for identifying archaeological pigments and for diagnosing their deterioration products. Conducting scientific methods of analysis, the pigments identified in this study are reported for the first time to be used in Persian wall paintings. © 2014 Elsevier B.V. All rights reserved.

Land use planning seeks to divide land, the most valuable resource in the hands of planners, among different land types. During this process, various conflicting objectives are emerged which land use planners should prepare land use plans satisfying these objectives and deal with a large set of data and variable. For this reason, land use allocation is a multi-objective NP-hard optimization problem which is not solvable by the current exact methods. Therefore, solving land use optimization problem relies on the application of meta-heuristics. In this paper, a novel meta-heuristic named parallel particle swarm is developed to allocate seven land types (residential, commercial, cultural, educational, medical, sportive and green space) to Baboldasht district of Isfahan covered by 200 allocation cells with size 1000 m2 for maximizing compactness, compatibility and suitability objective functions. Afterwards, the outputs of the new developed algorithm are compared to the outputs of genetic algorithm. The results demonstrated that the parallel particle swarm is better than genetic algorithm in terms of both solution quality (1.35%) and algorithm efficiency (63.7%). The results also showed that the outputs achieved by both algorithms are better than the current state of land use distribution. Thus, the method represented in this paper can be used as a useful tool in the hands of urban planners and decision makers, and supports the land use planning process. © 2016 Journal of Urban and Environmental Engineering (JUEE).

Corrosion layers in some copper and bronze archaeological objects from Haft Tappeh archaeological site, southwest Iran, were studied. For this purpose, optical microscopy, scanning electron microscopy with energy dispersive X-ray microanalysis, micro-Raman spectroscopy and X-ray diffraction methods were applied to observe corrosion stratigraphy and their characteristics as well as identification of chemical composition and phase determination of different corrosion layers. Based on optical and electron microscopy, three different corrosion strata were identified in cross section of different metallic objects including various red, green, white-grey powdery and dark internal compact layers. Scanning electron microscopy with energy dispersive X-ray microanalysis on different corrosion layers revealed that Cu, Sn and Cl are the main elements in the chemical composition of different layers. Tin-rich phases were detected in white-grey and dark layers that may be formed because of the internal oxidation of tin as well as the decuprification (selective dissolution of copper) phenomena occurring during long-term burial period in the soil. Also, the XRD and micro-Raman spectroscopy results proved that the main corrosion products are nantokite (CuCl), copper trihydroxychlorides and copper oxides. The combination of these analytical methods allows us to explore the surface and internal corrosion layers of the archaeological copper and bronze samples, and major interest is on studying their chemistry, microstructural properties and corrosion stratigraphy. © 2015 John Wiley & Sons, Ltd.
