Abstract:
Due to the unconventional nature of the blended wing body (BWB) no off-the-shelf software package exists for its conceptual design. This study details a first step towards the implementation of traditional and BWB-specific design and analysis methods into a software tool to enable preliminary sizing of a BWB. The tool is able to generate and analyze different BWB configurations on a conceptual level. This paper investigates three different BWB configurations. The first configuration is an aft-swept BWB with aft-mounted engines, the second configuration is an aft-swept BWB with wing-mounted eng

Abstract:
The BWB-UG is a glider with a smooth and integrated fuselage and wing. Its lift-to-drag properties are some of the most significant factors affecting its performance. In order to improve its hydrodynamic characteristics, the method of steady-stream active flow control (SS-AFC) is proposed. The computational fluid dynamics method is used to numerically investigate the SS-AFC of the BWB-UG. The mechanism of the SS-AFC effect on the lift-to-drag characteristics is revealed from the flow field aspect. The flow field of the BWB-UG before and after installing the SS-AFC was simulated using FLUENT. T

Abstract:
Black wheat bran (BWB) is an important source of dietary fiber (DF) and phenolic compounds and has stronger nutritional advantages than ordinary WB. However, the low content of soluble dietary fiber (SDF) negatively influences its physicochemical properties and nutritive functions. To obtain a higher content of SDF in BWB, we evaluated the impact of co-modification by extrusion and enzymes (cellulase, xylanase, high-temperature α-amylase, and acid protease) on water extractable arabinoxylan (WEAX) in BWB. An optimized co-modification method was obtained through single-factor and orthogonal exp

Purpose Blended wing body (BWB) is a very advantageous design in terms of low fuel consumption, low emission and low noise levels. Because of these advantages, the BWB is a candidate to become the commercial passenger aircraft of the future by providing a paradigm shift in conventional designs. This paper aims to propose a key design parameter for wing sizing of subsonic BWB and a performance parameter for calculating the lift/drag ratio values of BWBs.

Currently developed underwater gliders can be roughly divided into the two types:traditional configuration and unconventional configuration. As a type of underwater gliders with unconventional configuration, a blended-wing-body (BWB) underwater glider has better fluid dynamic performances because of its unique shape. However, it is difficult to design the shape of the BWB underwater glider that has excellent hydrodynamic performances. Therefore, it is of great significance to optimize its shape, which this paper carries out by using the free-form deformation (FFD). The complete and automatic s

Abstract:
Since the Biological Weapons Convention (BWC) opened for signature in 1972, biology and other converging disciplines have advanced considerably. These changes could have profound implications for a science-based disarmament agreement like the BWC. To address changes in biology and biotechnology, BWC States Parties have established processes to review developments in science and technology (S&amp;T), including annual expert meetings on this topic. However, shortcomings are evident in the current approaches and many BWC States Parties have expressed support for a more systematic review of scienc

Abstract:
The bronze birch borer (BBB), Agrilus anxius, is a significant pest native to North America, affecting birch trees (Betula spp.). Its larvae burrow through the cambial layer, causing tree decline and mortality, especially in stressed North American birches and healthy European and Asian birches. Although endemic in North America, BBB has caused widespread damage, particularly in urban areas and during droughts. The pest poses a potential threat to European and Asian birch forests if it were to spread. Currently, there is no history of classical biological control against BBB. Several natural e

Abstract:
At the Ninth Review Conference of the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on their Destruction (BWC) in 2022, States Parties agreed to establish a new Working Group on the strengthening of the Convention, which will operate during the next intersessional period between 2023 and 2026. The agenda for the Working Group includes discussion on, among other things, compliance and verification. This is the first time in 20 years that verification will be formally discussed within the BWC framework, initiati

Abstract:
Smart packagings for detecting climacteric fruit freshness were prepared based on low density polyethylene (LDPE)/chromophores (bromothymol blue) modified PCH (PCH-BTB) nanocomposite films. The incorporation of chromophores in porous materials was investigated by N₂ adsorption-desorption, XRD and SEM. The nanaocomposite was prepared by twin screw extruder and fabricated into nanocomposite film by compression molding. The color change of LDPE/PCH-BTB nanocomposite films from green to yellow correlated with standard CO₂ levels, which can be compared to CO₂ levels from respiration during fruit ri

Abstract:
Although Parkinson’s Disease (PD) is the second most prevalent neurodegenerative disease in the U.S., the pathology remains an enigma. Many neuroinflammation hypotheses have been studied to explain its development. It’s shown that inflammatory markers such as COX-2 activity, which synthesizes the potent vasodilator PGE2, are overexpressed in PD. Additionally, astrocytes, regulators of inflammation in the brain and BBB, undergo important changes during PD. However, the vascular consequences that all this has for PD-led neurodegeneration are relatively unexplored. We conducted a systemic review

Abstract:
Progress in international cooperation under Article X of the Biological Weapons Convention (BWC) is a prerequisite for success at the Ninth BWC Review Conference. This requires fresh thinking around options for Article X. To this end, UNIDIR sought input from a diverse range of experts on ideas for advancing Article X, with a particular focus on the promotional aspects of this important article. Building on the contributions of authors, this report outlines ten concrete ideas for States Parties to consider in seeking to enhance the implementation of Article X of the Biological Weapons Conventi

More than halfway through the implementation of the Philippine Development Plan (PDP) 2017-2022, it is deemed important to examine the contribution of the "Build, Build, Build" (BBB) program in the attainment of the PDP targets considering the programs huge fiscal implications. In this light, the study aims to delve into the BBB program and the projects that comprise it as good understanding of the program is critical in examining its implications on the PDP targets. The BBB program should be clearly defined in terms of what it really is and what it covers. Based on available data and informat

Abstract:
Biosecurity and biosafety are important aspects of the life sciences and they have been discussed in the Biological Weapons Convention (BWC) on several occasions. Moreover, several initiatives are underway to advance biosecurity and safety. However, these initiatives are often context specific and the effective implementation of biosecurity and biosafety measures around the globe remains inadequate. To address this gap, in 2022, France, Senegal and Togo submitted a revised proposal to the BWC for the “establishment of an international platform dedicated to biosecurity and biosafety: SecBio”. T
