A conceptual and feasibility study of an RBCC SSTO catapult-launched reusable strap-on parallel-boosted gliding-reentry lifting-body spaceplane for economic manned short-duration 300-kg payload LEO access is presented an...

The fashion industry faces increasing pressure to adopt sustainable practices due to its environmental impact and resource consumption. Digital traceability and innovative technologies have emerged as key tools to enha...

Stellar-mass black holes (BHs) surrounded by neutrino-dominated accretion flows (NDAFs) are a leading central engine of gamma-ray bursts (GRBs). In this work, we investigate the electron fraction distribution in NDAFs wi...

The development of ready-to-eat side dish products with gravy in retort pouches is based on the public's desire for quick, portable, and stable food options. This research aimed to examine the sterilization processes of ...

Abstract In this study, the effects of fuel blend ratio and engine speed on the performance and emissions of a spark-ignition (SI) engine fueled with gasoline–isopropanol blends were experimentally investigated, modele...

Ammonia/diesel blended fuel significantly reduces carbon emissions, but it has issues such as high unburned ammonia emissions and low combustion efficiency. To achieve the goals of carbon peak and carbon neutrality, this...

The aerospike engine was first devised in the early 1960s where it provided new means of reaching orbit in a single stage. The paper aimes to demonstrate the viability of the technology by showcasing the increased nozzle...

Abstract Background The internet has become an important source of information for cancer patients. Numerous websites provide nutritional advice that promises benefits for the outcome of cancer therapy. The aim of our st...

Unbalanced field length exists when ASDA and TODA are not equal. Airport authority may add less expensive substitutes to runway full-strength pavement in the form of stopways and/or clearways to basic TORA to increase op...

The objectives of the current study are to assess the performance and emission characteristics of a diesel engine running on Juliflora biodiesel-based blends at varying levels of brake power. These ob-jectives were achie...

Abstract This study was conducted to elucidate the combined effects of intake-air temperature (IAT), excess air ratio (λ), and fuel blend composition on the combustion behavior of an HCCI engine. Three butanol/diethyl e...

The objective of this study is to enhance the energy efficiency and environmental safety of boiler plants and engines equipped with waste heat recovery boilers. This objective is achieved by utilizing water-fuel emulsion...

This Campbell systematic review examines the impact of reducing the maximum duration of unemployment benefits on job‐finding rates. Seven studies were included in the review, all of which are from European countries. I...

Abstract Background Limited knowledge regarding the relative effectiveness of workplace accident prevention approaches creates barriers to informed decision‐making by policy makers, public health practitioners, workpla...

Spray burners form an essential part of any liquid propulsion system as they are responsible for injecting, atomizing, mixing and combusting the liquid fuel. Spray combustion used in aerospace applications like the liqui...

This paper presents a methodology to manage the support to design in ATM operations. We propose a workflow for the design of ATM solutions in a performance-based setting. The methodology includes the evaluation of the im...

The main objective of this Campbell systematic review was to provide a systematic review of the evidence on the effects of microcredit on women's control over household spending in developing countries. More specifically...

Abstract The article discusses complacency and the five hazardous attitudes in the context that the five hazardous attitudes are a subset of complacency. On the list of 12 most common contributors to aircraft accidents,...

Abstract Background Class size reductions in general education are some of the most researched educational interventions in social science, yet researchers have not reached any final conclusions regarding their effects. ...

The main objectives of the study are to develop a generalized thermo-electromechanical model of a solid-state heat engine based on a Ni-Ti-Cu shape memory alloy for converting low-grade thermal energy (30-100 °C) into e...

Abstract Background Video‐based interventions (VBIs) are an approach that can be used to promote social behavioural skills for autistic children and young people. Despite an abundance of literature in this area, previo...
