Compte tenu de l’importance socioéconomique et alimentaire du riz, les producteurs ont utilisé plusieurs systèmes de culture pour mieux assurer la compétitivité de leurs exploitations. La présente étude a consisté en une analyse de l’efficacité économique des systèmes de culture du riz en bas-fonds. Un échantillon de 283 producteurs a été constitué de façon aléatoire. L’approche stochastique des frontières de production et de coût a permis d’estimer et de décomposer l’efficacité économique en ces deux composantes (efficacité technique et efficacité allocative).

Resumen

The costs borne by road infrastructure authorities for managing and maintaining road devices such as safety barriers may be very high. This has prompted the need for identifying and analysing in detail all factors that influence the costs of safety barriers throughout their service life. To meet that need, the authors used international experience and field data collected under the LifeRoSE project to define the cost structure and, as a next step, to analyse factors that are relevant to the costs actually incurred.

Resumen

Abstract Technological progress is reflected in all industries. Obsolete project manuals in the construction industry are being replaced by digitized automated controls that monitor the project in real-time. One of the main trends is the introduction of technologies based on data analytics. Effective use of technology to collect and analyse data is key to improving a building's planning and management across its life cycle. Building information models, which process digital content related to the entire life cycle of a building, are becoming an effective tool. The main goal of the paper is to

Resumen

This report will analyse and evaluate the most recent and significant trends in combined cycle gas turbine (CCGT) power plant configurations. The various enhancements will be compared with the ‘simple’ gas turbine. The first trend, a gas turbine with reheat, cannot convert its better efficiency and higher output into a lower cost of electrical power. The additional investments required as well as increased maintenance costs will neutralize all the thermodynamic performance advantages. The second concept of cooling the turbine blades with steam puts very stringent requirements on the blade mate

Sustainable construction and the design of low-carbon structures is a major concern for the UK construction industry. FRP composite materials are seen as a suitable alternative to traditional construction materials due to their high strength and light weight. Network Rail has developed a prototype for a new innovative footbridge made entirely from FRP with the aim of replacing the current steel design for footbridges. This study conducted a life cycle analysis of this novel composite footbridge design to quantify the cost and environmental benefits. An LCA and LCC analysis framework was used t

Resumen

When it comes to Construction industry, Quality is quite important. It matters a lot to the Construction Project. The quality of a product, which relates to the perception of the degree to which the goods or services matches the customer's expectations. There are several approaches for improving the quality of construction projects. Some of the modern tools include Fish Bone Diagram, Deming Cycle, Histogram, Flowchart, Decision Matrix etc. In this Case study on the leaning tower of Pisa, the quality element of the construction is described utilising inventive and flexible tools and techniques.

Resumen

Electric vehicles are a leading candidate in the clean energy market. This paper aims to analyse the feasibility of the deployment of electric buses (EB) based on the existing bus routes in Brunei, by the use of life cycle cost analysis and the analysis of the parameters that influence the overall life cycle cost. The findings from the study revealed that EB are significantly more expensive than diesel buses (DB), with their acquisition and maintenance costs contributing substantially to their overall life cycle cost. In order to promote EB deployment, the government needs to look simultaneous

Purpose This paper aims to explore synergies between lean production (LP) and six sigma principles to propose a lean six sigma (LSS) framework for continuous and incremental improvement in the oil and gas sector. The Three-dimensional LSS framework seeks to provide various combinations about the integration between LP principles, DMAIC (define–measure–analyse–improve–control) cycle and plan-do-check-act (PDCA) cycle to support operations management needs. Design/methodology/approach The research method is composed of two main steps: diagnosis of current problems and proposition of a conceptual

Purpose: The aim of the study was to analyse the possibility of introducing vacuum carburising technology with pre-nitriding in the aviation industry. Design/methodology/approach: The samples have been tested with new technology and the planet gear requirements for aviation applications were determined. The effect of pre-nitriding technology used before vacuum carburising was also investigated for antidiffusional surface protection. A cost analysis of replacing the conventional technology with a new low-pressure carburising technology has also been introduced. Findings: Structural characterist

Resumen

The amount of plastics deposited in the environment is constantly increasing. To improve their circularity, numerous research lines emerge, such as the creation of new construction materials that incorporate polymeric waste. This practice manages to extend the life cycle of the waste, avoids the consumption of limited natural resources and gives the product additional characteristics. The re-use of polyurethane foam waste as a substitute for gypsum in ceiling tiles carries technical improvements such as a decrease in the weight of the material and in its thermal conductivity, maintaining a pos

Despite the fact that the incidence and mortality rates due to dengue virus (DENV) infection in Indonesia are relatively high, dengue vaccination has not yet been introduced. This study aimed to analyse the cost-effectiveness and the budget impact of dengue vaccination in Indonesia by taking the potential of pre-vaccination screening into account. An age-structured decision tree model was developed to assess the cost-effectiveness value by applying a single cohort of 4,710,100 children that was followed-up in a 10-year time horizon within a 1-year analytical cycle. The budget impact was analys

Resumen

Background: This ongoing coronavirus disease 2019 (COVID-19) pandemic is a great challenge for our health-care systems and their infrastructure. Diagnostic confirmation of infected individuals based on RT-PCR is important for the containment of viral spread because, despite high viral loads, the infection can be asymptomatic. For overcoming the issue of limited supplies in low socio-economic countries like ours, pooling of specimens was proposed as a method to screen a large number of patients. To analyse the effect of pooling of samples on the sensitivity of RT-PCR, we compared Cycle threshol

Resumen

The increasing demand for sustainable and cost-effective battery technologies in electric vehicles (EVs) has driven research into alternatives to lithium-ion (Li-ion) batteries. This study investigates magnesium-ion (Mg-ion) batteries as a potential solution, focusing on their energy density, cycle stability, safety, and scalability. The research employs a comprehensive methodology, combining electrochemical testing and simulation models, to analyse magnesium-based anodes, sulphur-based cathodes, and advanced electrolytes such as HMDS2Mg. Key findings reveal that Mg-ion batteries achieve a pra

The social cost of carbon repre-sents the present value of the global damages of climate change attributable to the emission of an additional ton of carbon dioxide into the atmosphere.

RÉSUMÉ Afin de pouvoir évaluer le degré auquel les politiques gouvernementales d’aide et de soutien aux familles compensent les coûts économiques reliés à la prise en charge d’un enfant, il importe de disposer d’une estimation du coût de l’enfant. Dans cet article, l’auteur présente un nouveau modèle d’estimation de ce coût, et l’applique aux données de l’enquête de Statistique Canada sur les dépenses des familles en 1982.

Resumen

Urban parcel delivery is increasingly restricted by regulations limiting access to certain heavy or high emitting vehicles to reduce emissions and noise pollution in cities. Cargo bikes represent an alternative solution that enables deliveries with low environmental impact, but they may represent a higher economic cost and come with constraints like battery autonomy or small loading capacity. As a transport scheme relying on bikes for the last miles with fewer externalities, it is regarded as an environmentally friendly choice, and economic sustainability is assessed.
