Academic literature on the topic 'Mummy cases – Egypt – Design and construction'

Egypt is among one of the world’s richest countries in the diverse architectural heritage resulting from the various civilizations that have arisen on the land of Egypt. However, the architectural heritage in Egypt suffers from multiple problems represented in the poor handling of the heritage site and the lack of protection for those sites. Which lead to the deterioration of the situation of some sites, and with the technological advances that the world is witnessing today in all spheres of life. Virtual Heritage Technology is emerging as one of the solutions that can be used in heritage sites in Egypt. This is one of the latest and most innovative technologies for the virtual environment, which is emerging as an integral part of it, and it is the reconstruction of historical sites as they were at the beginning of their construction. This depends on re-documentation of architectural buildings and heritage sites in detail through 3D models and holographic drawings. It also depends on many techniques and one of those that are often used in the applications of the virtual heritage are augmented reality technology, which is used to reconstruct archaeological sites in the site, by using tools or devices that support that technology, whether from portable smartphones or through devices that are worn like glasses and contact lenses. The virtual heritage technology offers many advantages to heritage sites, where it is considered historically as a digital documentation process for heritage which ensures that the artistic and historical value of buildings and heritage sites are preserved. It can also be used in the process of restoration of buildings; in addition to economic assistance in further enhancing heritage sites that attracts many tourists and visitors, which gives them the possibility to view the history of archaeological sites interactively; allowing them the sensory and intellectual integration with the site and this contributes to obtain historical information. This research will examine the possibility of utilizing the technology of virtual heritage through its application in the heritage sites in Egypt and the cultural and economic impact of the use of such technology on heritage sites. In addition, some virtual design cases will be discussed for heritage sites around the world and a SWOT analysis would be made to exemplify the challenges and discuss how they may be addressed. These examples are then presented to demonstrate how to deal with some of the difficulties, taking into account the arrival of proposals and recommendations that can be used and applied in Egypt.

The quantity of municipal solid waste (MSW) generation is escalating at an alarming rate with every passing year alongside the modernization of our economy. Unfortunately, the majority of this waste remains uncollected or ends up in open dumping and followed by uncontrolled burning. Citing the deep-rooted consequences, open dumping should be absolutely abandoned and scientific interventions should be aggressively exercised to reclaim the municipal brownfields. The present research work undertook the judicial task of assessing the comparative feasibility of biomining and scientific capping as a technology selection for reclamation of about a decade old 120 million tons of waste chunk laying at Jawahar Nagar dump yard. Primary dump samples were collected from various locations, considering depth as a variable. While leachate and groundwater samples were collected from Malkaram lake and preinstalled borewells receptively. Additionally, the ambient air quality and noise level also been ascertained within the buffer zone. The blended representative solid sample was segregated using a 70 mm mesh size trommel into organic and inorganic fractions. The organic fraction was composted using a lab-scale aerobic static pile composting (ASPC) while the trommel reject was processed as refuse derived fuel (RDF). Evidently, the compost lagged quality and depicted nutrient deficiency. While the burning of RDF produced siloxane gas, significantly due to elevated silicon level in the primary waste. Furthermore, due to the prolonged leaching tenure and seasonal dilution, the concentration of legacy leachate was relatively weaker. Borewell samples collected from a depth of 20 feet also portrayed minor contamination up to 500 meters horizontal radius. The issue of leachability can solely be resolved with the capping of the existing dump and the end product quality derived from the biomining process is highly questionable. Thus, handling such large quantity capping is a befitting option over biomining for Jawahar Nagar dumpsite. INTRODUCTION Presently, in India due to rapid urbanization and industrialization, the generation of MSW has been increasing tremendously and also expected to continue a similar trend in the future (Scott, 1995; Bhat et al., 2017; Sethurajan et al., 2018; Sharma et al., 2018). Annually, the comprehensive urban MSW generation in India is more than 62 million tons. Metro cities are the mammoth contributor of the entire chunk and waste production had already reached an alarming figure of 50,000 tonnes/day. While the waste generation from the tier 2 cities is also rigorously escalating and presently contribute up to 20,000 tones/day (Sharma et al., 2018). A study conducted by the central pollution control board (CPCB) revealed MSW generation in India is increasing at a distressing rate of 5 % per annum with a sharp escalation in the quantities of domestic hazardous waste (Sharma et al., 2018). With major financial constraints, inefficacy of collection, treatment, and disposal incurs further reasons to worry. So far India has miserably failed to set up wholesome source segregation and collection method. Presently, the country spends more than 60% of its annual waste management budget only in collection. Besides, only 20% or less of the collected materials are scientifically handled and treated. Citing the statistics, it is evident that the majority of the MSW is simply gets dumped on the low laying grounds located somewhere on the outskirts of the cities. The precipitation, infiltration, surface water runoff, bird menace, rodent interference etc. triggers the vulnerability of waste and leads to mal odor, ground and surface water contamination, human and environmental health deterioration (Jayawardhana et al., 2016). Further, the perseverance of the inorganic and inert fractions leads to soil contamination, poses a fire threat, and also may incur carcinogenicity and acute toxicity among the animals (Mir et al., 2021). There are numerous techniques for the reclamation and remediation of the dumpsites, includes processes such as capping and closure, in-situ vitrification, sub-surface cut-off walls, and waste biomining (Chakrabarti and Dubey, 2015; Thakare and Nandi, 2016). Waste biomining is a stable way to get rid of the entire range of problems associated with open dumping and reclaim valuable land (Kaksonen et al., 2017). There are several instances including reclamation of Mumbai Gorai dump yard by IL & FS Environment, 70 – 80 years old 12,00,000 tons of dump clearance by Nagar Nigam Indore within a minute span of 3 years and many more. But the process of biomining is highly sensitive and case-specific. The success of the process solely depends on factors such as characteristics of the waste, efficacy of the effective microorganism culture, acceptability of the processed end product at the local market etc. (Jerez, 2017; Banerjee et al., 2017; Venkiteela, 2020). Contrarily, though the scientific capping is not an end-to-end solution but still advisable in the cases where the quantity of waste is gigantic, land scarcity is prevalent, no nearby industries to consume the end products etc. Mehta et al. (2018) have also supported the above claim based on the assessment of locations specific MSW dump reclamation case studies. While in another Nagpur-based case study conducted by Ashootosh et al. (2020) reported the superiority of the biominingprocess over simple land capping due to the favorability of the local conditions. Capping eliminates the environmental interference and thereby reduces biosphere contamination and leachate generation. Further, it captivates rodent and vector breeding and thereby curtails the spreading of communicable diseases and improves aesthetics. But right consolidation through compaction and execution is utmost necessary in the above case. As non-compaction and faulty sloping will easily lead to heavy settlement and slope failure (Berkun et al., 2005; Al-Ghouti et al., 2021). The present study has been pursued with the primary objective to run a techno-commercial assessment between scientific capping and biomining. While the secondary objective was to ascertain the level of contamination and propose mitigative measures. MATERIALS AND METHODStudy Area Spanning over 350 acres of a precious piece of land at the outskirts of Hyderabad city, Jawahar Nagar dumping yard was brutally utilized by the Greater Hyderabad Municipal Corporation (GHMC) for open dumping for a prolonged tenure of 10 years. It housed nearly 12 lakh metric tons of heterogeneous solid and domestic hazardous waste and continues polluting until 2015, until the Ramky group was offered to cap the legacy dumping and scientifically handle the site. The present study has been facilitated at Hyderabad Municipal Solid Waste Limited, formerly known as Jawahar Nagar dump yard to analyze and assess the feasibility of bio-mining as handling and management alternate to the existing practice of scientific capping. The epicenter of processing and disposal facility is lying approximately on the cross-section of 17°31'24.45"N and 78°35'23.37"E. As per the contract, the comprehensive legacy dumping to be capped in three phases over about 150 acres of area and Ramky has significantly entered the phase two of the operation only within a span of five years by successfully capping more than half of the legacy footprint. Sampling Methodology The waste pile was divided into three layers namely, base, middle, and top. A uniform amount of sample was collected from the successive layers of all five different corners which cover north, south, east, west, and central of the garbage pile. Sampling inspections were performed using a manual auger besides large samples were collected using a JCB excavator. The top six-inch layer of the pile was removed to avoid any contamination while collecting the samples and 5-10 kg of sample was collected from each of the locations. Further, intermediate and bottom layer samples were collected by digging a 500 mm diameter hole through the heap. A composite was prepared by a homogenized blending of all the fifteen grub samples. The blend was distributed into four equal quadrants and the top and bottom quadrants were eliminated diagonally while the left-over quadrants were mixed thoroughly. This process was repeated until a sample of the required bulk of 20 kg is obtained. Surface and subsurface water samples from borewell were collected in and around the facility. Piezometric monitoring borewells located near the landfills were utilized for the subsurface sample collection. While a rainwater pond turned leachate lake named Malkaram was determined as the primary source for leachate collection. Buffer samples were collected from Ambedkar Nagar, the nearby colony exiting at a distance of only 300 meters. Lab-scale Experimentation The representative sample was characterized for composition and further screened through a 70 mm mesh size trommel. The trommel permeate was considered as the organic fraction while the reject was mostly inorganics and inert. The organics were subjected to ASPC. The quantity of the air required is arrived using the method delineated below (Figure 1). MSW Pile size: 2m x 0.5m x 0.5m Volume of pile: 0.5 m3 Average Density of MSW: 620 Kg/m3 Weight of pile: 310 Kg Nitrogen required for matured compost: 9300 mg/kg dry : 9300 X 310 mg : 2.88 x 106 mg : 2.88 Kg Total air required: 2.88 x 100/76 [as Nitrogen in air is 76% by weight] : 3.79 Kg of dry air : 3.79/1.225 m3 [@ 15 deg C density of air 1.225 kg/m3] : 3.1 m3 This air is to be supplied for 100 min / day for 0.5 m pile Air flow rate required: 3.1 x 60/100 = 1.86 m3/h (for practical purpose a flowrate of 2 m3/h was maintained). The maturation period was considered as 28 days and post-maturation, the stabilized material was further cured for 24 hours and screened using 12 mm and 4 mm trommel respectively to obtain the desired product quality and particle size. Whereas, the trommel reject was evenly spreader on the copper trays and dried in an oven at 1050C for 2 hours. The dried material was micronized to the size of 50 mm or below using a scissor and inert such as glass, sand, stone etc. were segregated manually (Mohan and Joseph, 2020). Concurrently, a bench-scale capped landfill prototype was built using the below-mentioned procedure to evaluate the factors such as settlement and slope stability. A 30 mm thick low permeable soil was laid on the top of the waste, followed by a 60 mm layer of compacted clay liner (CCL). Each join between successive liner material was closely monitored. A 1.5 mm thick HDPE liner was placed on the top of the CCL. A 285 GSM geotextile membrane was placed as the successive above layer followed by a 15 mm thick drainage media layer. A further layer of geotextile membrane was placed on top of the drainage media for better stabilization, grip, and strength. The top vegetative soil layer of 45 mm thickness was laid off on top of the geotextile media and St. Augustine grass was rooted (Cortellazzo et al., 2020; Ashford et al., 2000). 2.4 Sample Analysis pH, Electrical Conductivity (EC) and Turbidity of the samples were analyzed using pH, EC-TDS, and Nephelometer of Mettler Toledo. The pH meter was calibrated with the buffer solution of 4.0, 7.0 & 9.12 at a controlled temperature. EC-TDS meter was calibrated with 0.1 M KCL having 12.8 mS/cm of conductivity. Nephelometer was calibrated with Formazine solution of 10 & 100 NTU. Total Dissolved Solids (TDS), (mg/L) was performed using the gravimetric method at 1800C in the oven. Titrimetric parameters such as Total Alkalinity as CaCO3 (mg/L), Total Hardness as CaCO3 (mg/L), Chloride as Cl- (mg/L), Calcium as Ca2+ (mg/L), Residual Free Chlorine (RFC), (mg/L) were analyzed using APHA (American Public Health Associations) method, 23rd Edition, 2017. Total Kjeldahl Nitrogen (mg/L) and Ammonical Nitrogen (mg/L) were performed through distillation followed by titration with H2SO4 as a titrant. Sulphide as S2- was done with the Iodometric method after distillation. Each titrimetric parameter was analyzed in triplicate after standardizing the titrant with required reagents and crossed checked by keeping a check standard. Sodium as Na (mg/L) and Potassium as K (mg/L) were performed using Flame Photometer. The photometer was calibrated with different standards from 10 to 100 (mg/L) standard solutions. The leachate sample was diluted enough to get the value within the standard range and cross-checked with check standards at the same time. Chemical Oxygen Demand (COD), (mg/L) was performed using the open reflux method for 2 hours at 1500C in COD Digestor. Biochemical Oxygen Demand (BOD), (mg/L) was performed using the alkali iodide azide method for 3 days. The samples were kept in a BOD incubator at 270C for 3 days. It was kept in duplicate to have a check on quality control. Sulphate was analyzed by the gravimetric method instead of turbidimetric or through UV-Visible spectrophotometer as its concentration was found more than 40 mg/L. Nitrate as NO3- was analyzed after filtration at 220-275 nm, while Hexavalent Chromium as Cr6+ was analyzed at 540 nm in the UV-Vis. Parameters like Cyanide as CN-, Fluoride as F-, and Phenolic Compounds were gone through a distillation process followed by UV-Vis. The distillation process ensures the removal of interferences presents either positive or negative. For the parameters like Total Iron or Ferric Iron, the samples were digested properly with the required reagents on the hot plate before analyzing in UV-Vis. For the metal analysis the water samples were digested at a temperature of 1000C using aqua regia as a media. The samples were digested to one-fourth of the volume on a hot plate. The recommended wavelengths as per APHA 3120 B were selected for each of the metals. The standard graph was plotted for each of the metals before analysis and crossed checked with the check standard at the same time. Parameters such as bulk density and particle size were performed through the certified beaker and sieve. The percentage of moisture content was estimated using the oven by keeping the compost sample for 2 hours at 1050C. C/N ratio was estimated through CHNS analyzer keeping sulfanilamide as a check standard. The analysis was performed by extracting the desired component in the desired solution prescribed in the method followed by converting the same from mg/L to mg/Kg. RESULTS AND DISCUSSION An exhaustive bench-study has been pursued and real-time samples were collected and analyzed for all possible parameters to determine the pros and cons attributed to both processes. The investigation begins by collecting the samples and concluded by impact assessment studies inclusive of the buffer zone. Both solid, liquid, and gaseous samples were precisely investigated to opt for the best solution. A detailed finding of the investigation is summarized below. Primarily, the representative solid sample was characterized through a manual separation process and the results are portrayed in Figure 1. Compost Characterization ASPC of the organic fraction has resulted in a recovery of 46.7% of the initial load. While 53.3% of the influent mass were inert and barely degradable fraction contributes to reject, the rest 4.1% is miscellaneous process loss. The processed compost was extensively analyzed including for metal contamination and the same is tabulated in Table 1. The value of C/N ratio, OC, TN, K2O, P2O5, and NPK evidently portrays the shortcoming in terms of nutrient availability. Though it is highly enriched in organic carbon and thus the same can be effectively utilized as a soil preconditioner. Ayilara et al. (2020) also reported a similar finding, where the city compost sourced from MSW lagged major plant nutrients. RDF Characterization Processed trommel rejects constitute cloth, rexine, leather, jute, paper, plastics, coir and other inert contributed to RDF. The fraction of inert was as high as 37.2% of the overall RDF mass and it mostly constituted glass and sand. The combined weight of sand and glass fragments contributed 73.5% of the total inert, while the rest was stone and small brickbats. The higher level of silicon associated with the presence of glass and sand yielded siloxane and triggered the possibility of kiln corrosion. A detailed RDF analysis report is enclosed in Table 2. The values explicitly portray the quality of RDF is moderately lower and higher salts concentration is extremely prevalent. With relatively lower NCV and such high salt concentration, the above specimen will certainly pose a corrosion threat to the kiln and shall be either neglected as kiln feed or can be utilized after dilution with Grade III RDF quality. Further, such high ash generation will also induct high transportation and landfill charges. Leachate Characterization The Malkaram leachate lake is the end result of prolonged, slow, and steady mixing of the legacy leachate through the existing fissure cracks in the sheath rock bottom profile. Apparently, the concentration of leachate is significantly lower due to the dilution. Samples were analyzed in triplicates and the mean value is tabulated here in Table 3. The metal concertation and rest of the parameter values are well within the secondary treatment influent range, except for TDS. Thus, a modular aerobic biological treatment unit such as moving bed biofilm bioreactor (MBBR) or membrane bioreactor (MBR) would be a well-suited pick. However, a reverse osmosis (RO) system needs to be installed to get rid of the high TDS content. The permeate of RO can be reused back into the system. Whereas, the reject can be converted into dried powder through forced evaporation mechanisms. The higher concentration of salts in RDF collaterally justifies the elevated TDS level in leachate. In a leachate impact assessment study performed by El-Salam and Abu-Zuid (2015) the reported BOD/COD ratio of 0.69 is greater than double the value of 0.301 reported in Table 3. Though the difference in both the values are quite high, it is relatable and justifiable by the huge age difference of the source waste. The primarily characterized data is of a fresh leachate generated from regular MSW, while the later one is from a decade old waste that barely has any unstabilized organic content. Groundwater Contamination The obvious reason for downward leachate infiltration and osmotic movement facilitates groundwater contamination. Both surface and subsurface water samples were collected within the dump yard and the buffer zone and analyzed using the standard methods. The results are portrayed in Table 4. The slightly alkaline pH of the borewell sample is an indication of the ongoing anaerobic process. The dissolved oxygen value of 3.5 mg/L further validates the correlation. Higher TDS and hardness values are self-indicative of elevated salt concentration in source waste. Eventually, the same interfered with the RDF quality. Positively in the case of all the parameters, a successive decrement in pollution concentration has been spotted from dump ground towards the buffer zone. In a similar study conducted by Singh et al. (2016) at Varanasi, Uttar Pradesh the reported concentration of the parameters is significantly higher than reported in Table 4. The basic reason behind variation is the dissimilarities of the local soil profile. The sandy and clay loam soil profile of Varanasi allows a greater rate of percolation and infiltration. While the bottom sheath rock profile at Jawahar Nagar permits the only a minute to little percolation rate. The difference in percolation rate is directly correlated to the concentration levels in this case. Contrarily, Kurakalva et al. (2016) have reported much-elevated pollutant concertation both in ground and surface water for a study conducted at the same site in 2016. The higher concentration is relatable to the fact of the non-closure of the open dump back then. Capping activity had at Jawahar Nagar gained its pace 2018 onwards and capping for the primary section of 70 acres got concluded only during mid of 2019. Due to the decrement in runoff and percolation, the quality of both surface and subsurface water has improved drastically. Impact Assessment The odor and groundwater contamination are two of the primary issues that triggered a massive public agitation initially. The root causes of both the issues are identified as rainwater percolation and anaerobic digestion respectively. Eventually, the completion of the capping process would resolve both the problems effectively. Other non-tangential impacts include nausea; headache; irritation of the eye, nasal cavity, and throat; diarrhoeal diseases; vector-borne disease, cattle toxicity etc. Scientific capping can easily cater as the wholesome solution for all (Cortellazzo et al., 2020). Yu et al. (2018) had performed an extensive study to comprehend the relativity of respiratory sickness and MSW borne air pollution. The study made a couple of dreadful revelations such as gases released due to the anaerobic digestion of MSW such as methane, hydrogen sulphide, and ammonia incur detrimental impact on Lysozyme and secretory immunoglobulin A (SIgA). While SO2 was reported as the lung capacity and functionality reducer. Further, a gender-specific study executed by the same research group revealed, air pollution impacts more severely on male children than the female and retards immune functions. Presently, the area of 351 acres has been developed as Asia’s one of the largest state of the art municipal solid waste processing and disposal facility by Ramky Enviro Engineers Limited. This ensured zero dumping and no further environmental interventions. As legal compliance, the facility monitors the quality of groundwater and ambient air quality in and around the facility on monthly basis to assure the biosafety. The variation in concentration of various monitoring parameters between 2012 to 2020 is summarized in Figure 2. The concentration of each of the parameters are showcased in ppm and a standard equipment error was settled at 3% for respirable dust sampler and multi-gas analyzer (Taheri et al., 2014). Despite all parameter values have gradually increased except for methane, the facility still managed to maintain them well under the regulatory limits. The decrement in methane concentration is directly correlated to the practice of aerobic composting and aeration-based secondary treatment that prevented the formation of the anaerobic atmosphere and henceforth methane generation. While for the rest of the parameters the increment in values is quite substantial and predictable due to the sudden escalation in MSW generation in the past decade in correlation with Gross domestic product (GDP) enhancement. The observed and interpreted impacts due to the elevated pollutant level are in-line with the georeferenced findings reported by Deshmukh and Aher (2016) based on a study conducted at Sangamner, Maharashtra. CONCLUSION The study critically analyzed and investigated every techno-environmental and socio-economic aspect correlated to open dumping. The bench-scale experimentation revealed the efficiency of the single liner scientific capping is fair enough to eliminate any further rainwater infiltration, however, it has no control over the generation of leachate due to the inherent moisture. Internal moisture related issue was anyhow compensated with pertinent compaction prior to dispose of the waste. Contrarily, both the products derived through the biomining process namely, compost and RDF lagged quality due to scantier nutrient content and higher salt and silicon content respectively. Besides, impact assessment studies concede the pollutant concentration in groundwater in and around the plant has drastically diminished post-July 2019 due to the partial completion of waste capping. It also abetted lowering the dust and odor issues relatively in the surrounding.

Purpose This paper aims to develop a cultural diversity management (CDM) framework to enhance the performance of architecture design firms (ADFs) in Egypt. Design/methodology/approach A research methodology consisting of literature review, case studies and survey questionnaire was designed to achieve the abovementioned aim. First, literature review was used to investigate the concepts of globalization, international construction, diversity, diversity management (DM) and organizational performance. Second, four case studies were presented and analyzed. The first two cases explored the role of CDM towards enhancing the performance of ADFs, while the last two cases showed initiatives carried out by NGOs to integrate architects of color into their communities through training programs that enhanced their skills and uplifted their societies. Third, a survey questionnaire was carried out with a representative sample of ADFs in Egypt to investigate their perception and application of DM towards enhancing organizational performance. Based on the results of the above, the research developed a framework to enhance the performance of ADFs through managing culturally diverse workforces. Findings Literature review showed that diversity is not limited to race and gender; however, it includes other types such as disability, socioeconomic status, thinking style, culture, personality, life experience, religious and spiritual beliefs. Despite the benefits that diversity brings to ADFs such as stimulating creativity and increasing productivity, poor management of diverse workforce leads to dysfunctional conflicts, frustration and confusion. Results of case studies showed that ADFs that adopt a CDM approach succeeded in enhancing their performance. In addition, training initiatives carried out by NGOs succeeded to integrate architects of color into their communities and uplifting their societies. Results of data analysis identified the barriers to integrating diverse workforce in ADFs. These barriers include “Poor communication and spirit of collaboration between diverse workforce”, “Resistance to change”, “Lack of maintaining wage equity and promotion between different workforces based on gender”, “Poor organization culture” and “Lack of Senior Management involvement”. This necessitated taking action towards developing a framework to overcome these barriers to manage diverse workforces towards enhancing the performance of ADFs in Egypt. Research limitations/implications Because of the conceptual nature of the proposed framework, it has to be tested and validated to ensure its capability to overcome the barriers of managing culturally diverse workforces as an approach for enhancing the performance of ADFs in Egypt. Practical implications This research presents a practical solution to enhance the performance of ADFs in Egypt through managing cultural workforce diversity. Originality/value The research identified and analyzed the barriers that obstruct the integration of diverse workforces in ADFs. The research tackled a topic that received scant attention in construction literature with particular emphasis on Egypt. In addition, this paper proposed a CDM framework to enhance the performance of ADFs in Egypt, which represents a synthesis that is novel and creative in thought and adds value to the body of knowledge.

The acoustic environment of the classroom is deemed significant to enhance the learning quality and the learning outcomes. Noise exposure levels and reverberation are the main acoustic parameters to consider in the classroom because it affects speech intelligibility. As a result of the modern teaching methods especially in the practical faculties. Workgroup activities have become a common tool for learning, it has a higher noise level than independent work. Therefore, the specialists become face a great challenge to achieve acoustic comfort in classrooms. In spite of that, in Egypt, acoustic conditions are rarely implemented into classroom design practice. This study evaluated the acoustic performance of a typical classroom in Badr University, Egypt in unoccupied condition for four cases. Unoccupied ambient noise level (ANLs) and reverberation time (RTs) were measured by using Testo 815 device, and Ecotect software. Additionally, the measurements were compared with the standards and norms. Acoustic treatments using absorbent materials were suggested by simulation in Ecotect for three cases (four scenarios).

The principal intent of this paper was to propose a new quay wall system, whose validity was verified; to play the same role of the existing diaphragm quay wall at East Port Said Port in Egypt as an optimum quay wall. Firstly, the background information of the proposed Open Cell Sheet Pile (OCSP) was introduced. Then, a parametric study was conducted including 24 cases using soil constitutive Hardening Soil Model (HSM) by the PLAXIS 3D Finite Element Software. The behavior of the proposed system was presented graphically, and the effectiveness of the OCSP system was found satisfactory with the possibility to increase the seabed depth in front of the wall up to four meters. The system also was consisted of a bored piles group to carry the heavy loads generated by the gantry crane. Finally, the construction cost of the OCSP was compared to the existing quay wall structure system for evaluating the system design optimization.

AbstractTechnology has always been creating effective ways to support human decisions. Immersive virtual reality (IVR) has emerged to engage users in a simulated world, and this has gained the interest of a wide variety of users in the heritage industry. A historical case study built in the early 19th century is considered for an adaptive reuse exhibition. The palace is located in Cairo, Egypt, and named after Prince Omar Tosson. The current palace state incorporates a smashed top-lit zone, which is being studied and analyzed for daylighting adequacy. Three simulated distinct optimum skylight configurations are suggested for the redesign where the selection should not be based solely on simulation data, but should consider real-user preferences. Most daylight design criteria are previously based on simulation data that do not necessarily indicate the users’ preferences. But utilizing user interactive tools such as IVR to test daylight redesign options, a whole new dimension is provided. In this study, the VR users’ survey data is statistically analyzed using Statistical Package for Social Sciences (SPSS), where results revealed that the assessment attributes succeeded in reflecting the users’ preferences; which, motivated designers to consider potential users’ daylight preferences in reused spaces. The paper highlights the most significant emotional attributes that provide cost-effective and reliable information concerned with the performance of daylight in IVR before design implementation. This study compares and analyzes the effect of three skylight designs (Cases A, B & C) on the users’ perception before design implementation using (IVR) post-survey. Forty-eight participants have contributed to the study, providing their feedback on six attributes namely: Pleasant, Contrasting, Brightness, Uniform Distribution, Visual Comfort, and Satisfaction. Those attributes are evaluated for the three cases in space using five scale rating values to reveal that the “Pleasant” attribute is most reliable in the study to reflect the users’ preferences for design Case B.

To Remember‘The central problem of today’s global interactions is the tension between cultural homogenisation and cultural heterogenisation.’ (Appadurai 49)While this statement has been made more than twenty years, it remains more relevant than ever. The current age is one of widespread global migrations and dis-placement. The phenomenon of globalisation is the first and major factor for this newly created shift of ground, of transmigration as defined by its etymological meaning. However, a growing number of migrations also result from social or political oppression and war as we witness the current flow of refugees from Africa or Syria to Europe and with growing momentum, from climate change, the people of Tokelau or Nauru migrating as a result of the rise of sea levels in their South Pacific homeland. Such global migrations lead to an intense co-habitation of various cultures, ethnicities and religions in host societies. In late twentieth century Giddens explains this complexity and discusses how globalisation requires a re-organisation of time and space in social and cultural life of both the host and the migrant (Giddens 14). In the host country, Appadurai terms the physical consequences of this phenomenon as the new ‘ethnoscape’ (Appadurai 51). This fact is particularly relevant to New Zealand, a country that is currently seeing an unprecedented level of immigration from various and numerous ethnic groups which is evidently influencing the makeup of its entire population.For the migrant, according to Xavier & Rosaldo, social life following migration re-establishes itself on two fronts: the first is the pre-modern manner of being present through participation in localised activities at specific locales; the second is about fostering relationships with absent others through media and across the world. These “settings for distanced relations – for relations at a distance, [are] stretched out across time and space” (Xavier & Rosaldo 8). Throughout the world, people in dis-placement reorganise their societies in both of these fronts.Dis-placement is ‘a potentially traumatic event that is collectively experienced" (Norris 128). Disaster and trauma related dis-placement as stressors happen to entire communities, not just individuals, families and neighbourhoods. Members are exposed together and it has been argued, must, therefore, recover together, (Norris 145). On one hand, in the situation of collective trauma some attachment to a new space ‘increases the likelihood that a community as a whole has the will to rebuild’ (Norris 145). On the other, it is suggested that for the individual, place attachment makes the necessary relocation much harder. It is in re-location however that the will to recreate or reproduce will emerge. Indeed part of the recovery in the case of relocation can be the reconstruction of place. The places of past experiences and rituals for meaning are commonly recreated or reproduced as new places of attachment abroad. The will and ability to reimagine and re-materialise (Gupta & Ferguson 70) the lost heritage is motivational and defines resilience.This is something a great deal of communities such as the displaced Coptic community in New Zealand look to achieve, re-constructing a familiar space, where rituals and meaning can reaffirm their ideal existence, the only form of existence they have ever known before relocation. In this instance it is the reconstruction and reinterpretation of a traditional Coptic Orthodox church. Resilience can be examined as a ‘sense of community’, a concept that binds people with shared values. Concern for community and respect for others can transcend the physical and can bind disparate individuals in ways that otherwise might require more formal organisations. It has been noted that trauma due to displacement and relocation can enhance a sense of closeness and stronger belonging (Norris 139). Indeed citizen participation is fundamental to community resilience (Norris 139) and it entails the engagement of community members in formal organisations, including religious congregations (Perkins et al. 2002; Norris 139) and collective gatherings around cultural rituals. However, the displacement also strengthens the emotional ties at the individual level to the homeland, to kinfolk and to the more abstract cultural mores and ideas.Commitment and AttachmentRecalling places of collective events and rituals such as assembly halls and spaces of worship is crucially important for dis-placed communities. The attachment to place exposes the challenges and opportunities for recollecting the spirit of space in the situation of a people abroad. This in turn, raises the question of memory and its representation in re-creating the architectural qualities of the cultural space from its original context. This article offers the employ of visual representation (drawings) as a strategy of recall. To explore these ideas further, the situation of the Egyptian community of Coptic Orthodox faith, relocated, displaced and living ‘abroad’ in New Zealand is being considered. This small community that emigrated to New Zealand firstly in the 1950s then in the 1970s represents in many ways the various ethnicities and religious beliefs found in New Zealand.Rituals and congregations are held in collective spaces and while the attachment to the collective is essential, the question to be addressed here relates to the role of the physical community space in forming or maintaining the attachment to community (Pretty, Chipuer, and Bramston 78). Groups or societies use systems of shared meanings to interpret and make sense of the world. However, shared meanings have traditionally been tied to the idea of a fixed territory (Manzo & Devine-Wright 335, Xavier & Rosaldo 10). Manzo and Perkins further suggest that place attachments provide stability and are integral to self-definitions (335-350). Image by Vioula Said.Stability and self-definition and ultimately identity are in turn, placed in jeopardy with the process of displacement and de-territorilisation. Shared meanings are shifted and potentially lost when the resultant instability occurs. Norris finds that in the strongest cases, individuals, neighbourhoods and communities lose their sense of identity and self-definition when displaced due to the destruction of natural and built environments (Norris 139). This comment is particularly relevant to people who are emigrating to New Zealand as refugees from climate change such as Pasifika or from wars and oppression such as the Coptic community. This loss strengthens the requirement for something greater than just a common space of congregation, something that transcends the physical. The sense of belonging and identity in the complexity of potential cultural heterogenisation is at issue. The role of architecture in dis-placement is thereby brought into question seeking answers to how it should facilitate a space of attachment for resilience, for identity and for belonging.A unity of place and people has long been assumed in the anthropological concept of culture (Gupta & Ferguson: 75). According to Xavier & Rosaldo the historical tendency has been to connect the realm of constructing meaning to the particularities of place (Xavier & Rosaldo 10). Thereby, cultural meanings are intrinsically linked to place. Therefore, place attachment to the reproduced or re-interpreted place is crucially important for dis-placed societies in re-establishing social and cultural content. Architectural spaces are the obvious holders of cultural, social and spiritual content for such enterprises. Hillier suggests that all "architecture is, in essence, the application of speculative and abstract thought to the non-discursive aspects of building, and because it is so, it is also its application to the social and cultural contents of buildings” (Hillier 3).To Re-ImagineAn attempt to reflect the history, stories and the cultural mores of the Coptic community in exile by privileging material and design authenticity, merits attention. An important aspect of the Coptic faith lies within its adherence to symbolism and rituals and strict adherence to the traditional forms and configurations of space may reflect some authenticity of the customary qualities of the space (Said 109). However, the original space is itself in flux, changing with time and environmental conditions; as are the memories of those travelling abroad as they come from different moments in time. Experience has shown that a communities’ will to re-establish social and cultural content through their traditional architecture on new sites has not always resurrected their history and reignited their original spirit. The impact of the new context’s reality on the reproduction or re interpretation of place may not fully enable its entire community’s attachment to it. There are significant implications from the displacement of site that lead to a disassociation from the former architectural language. Consequently there is a cultural imperative for an approach that entails the engagement of community in the re-making of a cultural space before responding to the demands of site. Cultures come into conflict when the new ways of knowing and acting are at odds with the old. Recreating a place without acknowledging these tensions may lead to non-attachment. Facing cultural paradox and searching for authenticity explains in part, the value of intangible heritage and the need to privilege it over its tangible counterpart.Intangible HeritageThe intangible qualities of place and the memory of them are anchors for a dis-placed community to reimagine and re-materialise its lost heritage and to recreate a new place for attachment. This brings about the notion of the authenticity of cultural heritage, it exposes the uncertain value of reconstruction and it exhibits the struggles associated with de-territorilisation in such a process.In dealing with cultural heritage and contemporary conservation practice with today’s wider understanding of the interdisciplinary field of heritage studies, several authors discuss the relevance and applicability of the 1964 Venice Charter on architectural heritage. Glendinning argues that today’s heritage practices exploit the physical remains of the past for useful modern and aesthetic purposes as they are less concerned with the history they once served (Glendinning 3). For example, the act of modernising and restoring a historic museum is counterbalanced by its ancient exhibits thereby highlighting modern progress. Others support this position by arguing that relationships, associations and meanings that contribute to the value of a site should not be dismissed in favour of physical remains (Hill 21). Smith notes that the less tangible approaches struggle to gain leverage within conventional practice, and therefore lack authenticity. This can be evidenced in so many of our reconstructed heritage sites. This leads to the importance of the intangible when dealing with architectural heritage. Image by Vioula Said.In practice, a number of different methods and approaches are employed to safeguard intangible cultural heritage. In order to provide a common platform for considering intangible heritage, UNESCO developed the 2003 ‘Convention for the Safeguarding of Intangible Cultural Heritage’. Rather than simply addressing physical heritage, this convention helped to define the intangible and served to promote its recognition. Intangible cultural heritage is defined as expressions, representations, practices, skills and knowledge that an individual a community or group recognise as their cultural heritage.Safeguarding intangible heritage requires a form of translation, for example, from the oral form into a material form, e.g. archives, inventories, museums and audio or film records. This ‘freezing’ of intangible heritage requires thoughtfulness and care in the choosing of the appropriate methods and materials. At the same time, the ephemeral aspects of intangible heritage make it vulnerable to being absorbed by the typecast cultural models predominant at any particular time. This less tangible characteristic of history and the pivotal role it plays in conveying a dialogue between the past and the present demands alternative methods. At a time when the identity of dis-placed people is in danger of being diminished by dominant host societies, the safeguarding of intangible cultural heritage is critically important in re-establishing social and cultural content.Recent news has shown the destruction of many Coptic churches in Egypt, through fire at increasing rates since 2011 or by bombings such as the ones witnessed in April 2017. For this particular problem of the Coptic Community, the authors propose that visual representation of spiritual spaces may aid in recollecting and re-establishing such heritage. The illustrations in this article present the personal journey of an artist of Egyptian Copt descent drawing from her memories of a place and time within the sphere of religious rituals. As Treib suggests, “Our recollections are situational and spatialised memories; they are memories attached to places and events” (Treib 22). The intertwining of real and imagined memory navigates to define the spirit of place of a lost time and community.The act of remembering is a societal ritual and in and of itself is part of the globalised world we live in today. The memories lodged in physical places range from incidents of personal biography to the highly refined and extensively interpreted segments of cultural lore (Treib 63). The act of remembering allows for our sense of identity and reflective cultural distinctiveness as well as shaping our present lives from that of our past. To remember is to celebrate or to commemorate the past (Treib 25).Memory has the aptitude to generate resilient links between self and environment, self and culture, as well as self and collective. “Our access to the past is no longer mediated by the account of a witness or a narrator, or by the eye of a photographer. We will not respond to a re-presentation of the historical event, but to a presentation or performance of it” (van Alphen 11). This statement aligns with Smith’s critical analysis of heritage and identity, not as a set of guidelines but as a performance experienced through the imagination, “experienced within a layering of performative qualities that embody remembrance and commemoration and aim to construct a sense of place and understanding within the present”(van Alphen 11). Heritage is hereby investigated as a re-constructed experience; attempting to identify a palette of memory-informed qualities that can be applied to the re-establishing of the heritage lost. Here memory will be defined as Aristotle’s Anamnesis, to identify the capacity to stimulate a range of physical and sensory experiences in the retrieval of heritage that may otherwise be forgotten (Cubitt 75; Huyssen 80). In architectural terms, Anamnesis, refers to the process of retrieval associated with intangible heritage, as a performance aimed at the recovery of memory, experienced through the imagination (Said 143). Unfortunately, when constructing an experience aimed at the recovery of memory, the conditions of a particular moment do not, once passed, move into a state of retirement from which they can be retrieved at a later date. Likewise, the conditions and occurrences of one moment can never be precisely recaptured, Treib describes memory as an interventionist:it magnifies, diminishes, adjusts, darkens, or illuminates places that are no longer extant, transforming the past anew every time it is called to mind, shorn or undesirable reminiscence embellished by wishful thinking, coloured by present concerns. (Treib 188)To remember them, Cubitt argues, we must reconstruct them; “not in the sense of reassembling something that has been taken to pieces and carefully stored, but in the sense of imaginatively configuring something that can no longer have the character of actuality” (Cubitt 77). Image by Vioula Said.Traditionally, history and past events have been put in writing to preserve their memory within the present. However, as argued by Treib, this mode of representation is inherently linear and static; contributing to a flattening of history. Similarly, Nelson states; “I consider how a visual mode of representation – as opposed to textual or oral – helps to shape memory” (Nelson 37). The unflattening of past events can occur by actively engaging with culture and tradition through the mechanism of reconstruction and representation of the intangible heritage (Said 145). As memory becomes crucial in affirming collective identity, place also becomes crucial in anchoring such experience. Interactive exhibition facilitates this act using imagery, interpretation and physical engagement while architectural place gives distinctiveness to cultural products and practices. Architectural space is always intrinsically bound with cultural practice. Appadurai says that where a groups’ past increasingly becomes part of museums, exhibits and collection, its culture becomes less a realm of reproducible practices and more an arena of choices and cultural reproduction (59). When place is shifted (de-territorilisation in migration) the loss of territorial roots brings “an erosion of the cultural distinctiveness of places, a de-territorilisation of identity” (Gupta & Ferguson 68). According to Gupta & Ferguson, “remembered places have …. often served as symbolic anchors of community for dispersed people” (Gupta & Ferguson 69).To Re-MakeIn the context of de-territorialisation the intangible qualities of the original space offer an avenue for the creation and experience of a new space in the spirit of its source. Simply reproducing a traditional building layout in the new territory or recollecting artefacts does not suffice in recalling the essence of place, nor does descriptive writing no matter how compelling. Issues of authenticity and identity underpin both of these strategies. Accepting the historical tendency to reconnect the realm of constructing meaning to the particularities of place requires an investigation on those ‘particularities of place’. Intangible heritage can bridge the problems of being out of one’s country, overseas, or ‘abroad’. While architecture can be as Hillier suggests, “in essence, the application of speculative and abstract thought to the non-discursive aspects of building” (Hillier 3). Architecture should not be reproduced but rather re-constructed as a holder or facilitator of recollection and collective performance. It is within the performance of intangible heritage in the ‘new’ architecture that a sense of belonging, identity and reconnection with home can be experienced abroad. Its visual representation takes centre stage in the process. The situation of the Egyptian community of Coptic faith in New Zealand is here looked at as an illustration. The intangibility of architectural heritage is created through one of the author’s graphic work here presented. Image by Vioula Said.The concept of drawing as an anchor for memory and drawing as a method to inhabit space is exposed and this presents a situation where drawing has an experiential nature in itself.It has been argued that a drawing is simply an image that compresses an entire experience of temporality. Pallasmaa suggests that “every drawing is an excavation into the past and memory of its creator” (Pallasmaa 91). The drawing is considered as a process of both observation and expression, of receiving and giving. The imagined or the remembered space turns real and becomes part of the experiential reality of the viewer and of the image maker. The drawing as a visual representation of the remembered experience within the embrace of an interior space is drawn from the image maker’s personal experience. It is the expression of their own recollection and not necessarily the precise realityor qualities perceived or remembered by others. This does not suggest that such drawing has a limited value. This article promotes the idea that such visual representation has potentially a shared transformative role. The development of drawings in this realm of intangible heritage exposes the fact that the act of drawing memory may provide an intimate relationship between architecture, past events within the space, the beholder of the memory and eventually the viewer of the drawing. The drawings can be considered a reminder of moments past, and an alternative method to the physical reproduction or preservation of the built form. It is a way to recollect, express and give new value to the understanding of intangible heritage, and constructs meaning.From the development of a personal spatial and intuitive recall to produce visual expressions of a remembered space and time, the image author optimistically seeks others to deeply engage with these images of layered memories. They invite the viewer to re-create their own memory by engaging with the author’s own perception. Simply put, drawings of a personal memory are offered as a convincing representation of intangible heritage and as an authentic expression of the character or essence of place to its audience. This is offered as a method of reconstructing what is re-membered, as a manifestation of symbolic anchor and as a first step towards attachment to place. The relevance of which may be pertinent for people in exile in a foreign land.ReferencesAppadurai, A. “Sovereignty without Territoriality: Notes for a Postnational Geography.” The Geography of Identity.
