Manipulation of Dhaka cheese curd and effects on cheese quality

Dhaka cheese is a semihard artisanal variety originating from Bangladesh where manual curd kneading is a normal stage in its manufacture. Dhaka cheeses were produced with different degrees of curd kneading to quantify the curd manipulation process in terms of pressure and to standardise the length of operation. The effect of manipulation on the composition, rheology, texture and microstructure of fresh cheese was also studied. Manipulation had significant effects (P < 0.05–0.001) on most of the parameters studied. One minute of curd manipulation was found to be sufficient for Dhaka cheesemaking.     

Pressing technique and its effect on the quality of Dhaka cheese

Dhaka cheese is a semihard artisanal variety made mainly from bovine milk, using very simple pressing methods. Experimental cheeses were pressed at gauge pressures up to 31 kPa for 12 h at 24 °C and 70% RH. These cheeses were subsequently examined for their compositional, textural and rheological properties plus their microstructures investigated by confocal laser microscopy. The cheese pressed at 15.6 kPa was found to have the best compositional and structural properties.     

Evaluating Flood Hazard for Land-Use Planning in Greater Dhaka of Bangladesh Using Remote Sensing and GIS Techniques

Floods are a common feature in rapidly urbanizing Dhaka and its adjoining areas. Though Greater Dhaka experiences flood almost in every year, flood management policies are mostly based on structural options including flood walls, dykes, embankments etc. Many shortcomings of the existing flood management systems are reported in numerous literatures. The objective of this paper is to assess flood hazard in Greater Dhaka for the historical flood event of 1998 using Synthetic Aperture Radar (SAR) data with GIS data. Flood-affected frequency and flood depth calculated from the multi-date SAR imageries were used as hydrologic parameters. Elevation heights, land cover classification, geomorphic division and drainage network data generated from optical remote sensing and analogue maps were used through GIS approach. Using a ranking matrix in three dimensional multiplication mode, flood hazard was assessed. All possible combination of flood hazard maps was prepared using land-cover, geomorphology and elevation heights for flood-affected frequency and floodwater depth. Using two hazard maps which produced the highest congruence for flood frequency and flood depth, a new flood hazard map was developed by considering the interactive effect of flood-affected frequency and floodwater depth, simultaneously. This new hazard map can provide more safety for flood countermeasures because pixels belonging to higher hazard degrees were increased due to the consideration of higher degrees of ranks. The estimation of flood hazard areas revealed that a major portion of Greater Dhaka comprised moderate to very high hazard zone. Only a little portion (8.04%) was found to be the least vulnerable to potential flood hazard. Conversely, 28.70% of Greater Dhaka was found within very high hazard zone. Based on this study, comprehensive flood hazard management strategies for land use planning decision were proposed for the efficient management of future flood disasters.     

Inhabiting Time

In recent architecture, design has prioritised an engagement with time through its creation of temporary and highly flexible structures. There has, however, been less focus on how the design of buildings might impact the experience of time of the people who inhabit them. Here the distinguished author and emeritus professor Juhani Pallasmaa , who is renowned for his writings on the phenomenology of architecture, provides a reminder of the importance of what it means to ‘dwell in time’.     

Newness,Tradition and Identity: Existential Content and Meaning in Architecture

At a time when novelty and aesthetic invention have become the established norm for contemporary architecture, the esteemed Finnish author and architect Juhani Pallasmaa speaks out in defence of tradition. He explains how nuance, expressive subtlety and an ambition for an experiential and existential quality in a work require a sense of historical continuum: ‘An embodiment of the essence of tradition’ as a precursor for ‘meaningful creativity’.     

Reinforced concrete in Louis Kahn’s National Assembly,Dhaka: Modernity and modernism in Bangladeshi architecture

Louis Kahn is often credited with having in his National Assembly in Dhaka (1962–1983) introduced modern architecture to Bangladesh. In fact at least as technologically advanced construction as any he employed was already in use there. Nor was he the first to use a sophisticated abstract esthetic in what was from 1947 to 1971 East Pakistan. The importance and originality of the National Assembly instead resides in the care with which he built in reinforced concrete and the forms into which he required that it be cast. These were esthetic decisions rooted in a particular theoretical position; they were located outside established modernist practice of the time in both South Asia and the United States. Indeed operating at such a great remove from home may have heightened Kahn’s authority to implement these forms even as it substantially complicated their execution.     

Supersudaca’s Asia Stories (aka at Home in the First,Second, Third,Fourth and Fifth Worlds)

The architecture network Supersudaca is best known for its research projects on Latin America and the Caribbean. Here they describe their experiences as they shifted their focus to Asia and the Middle East in a super-tour that took in Kuala Lumpur, Tokyo, Dubai, Mumbai, Dhaka, Phnom Penh, Singapore and China.

Livability in dense residential neighbourhoods of Dhaka

Prime cities in developing countries, like Dhaka experience haphazard and intense horizontal densification. The livability of dense neighbourhoods needs to be investigated, particularly, the role of housing and planning in mitigating density problems and capitalizing the advantages of high-density living. This article argues that housing form and planned community facilities giving respect to socio-cultural practices can significantly influence Dhaka’s livability. Also, a wider definition of housing should be adopted to facilitate improvements in livability. As well, an integrated approach of residential planning is important in intensified housing development projects or planning for dense areas, encompassing housing standards, community facilities, public transport, open space provision and socio-cultural habits. This paper recommends the Bangladeshi Government to ensure enforcement of residential plans, to establish density zones in Dhaka’s main urban areas to guide spatial and transport development and neighbourhood facility provision, and to give greater respect for cultural practices in neighbourhood planning.     

Water table dynamics of Dhaka city and its long-term trend analysis using the “MAKESENS” model

The water table (WT) data of Dhaka city for 17 years (1988–2004) was analysed for assessing WT fluctuation and predicting its trend using a computer model, “MAKESENS”. The analysis revealed that the WT declined drastically at different locations of the city. Moreover, the model also predicted that WT would further decline 9–25 m by the year 2015 and 18–40 m by the year 2025, rendering most wells inoperative, if the pumping rate was not reduced.
