The triple-layered business model canvas as a tool for sustainable BSF farming: A case of smallholder farmers in Kenya

Smallholder farmers play an important role in providing food to the world, but they are at risk due to issues like climate change, soil erosion, and high feed costs. The livestock industry, especially poultry, pig, and fish farming, is seriously disadvantaged by Kenya's unsustain...

Structural insights and comparative electrocatalytic performance of citric acid-functionalized Luffa aegyptiaca and Pt-Pd/MWCNT-Luffa composites for the degradation of acetaminophen in aqueous media

Emerging contaminants, such as acetaminophen, pose a critical threat to aquatic ecosystems and human health due to their persistence in water and the difficulty of their removal using conventional methods. In this work, Luffa aegyptiaca biomass was valorized via citric acid funct...

Experimental investigation of the effects of transverse step position and height on the hydrodynamic performance of an asymmetric catamaran craft in calm water

High-speed catamarans are widely recognized among planing hull configurations due to their superior hydrodynamic stability. The incorporation of transverse steps can enhance performance by promoting flow separation, reducing wetted surface area, and consequently lowering resistan...

Numerical simulation and experimental investigation of continuous-pulse composite laser cleaning of dual-layer oxide scales on 50Mn steel

Efficient removal of oxide scales from 50Mn steel is important for maintaining the surface condition of load-bearing components. In this study, continuous-pulse composite laser cleaning was investigated for a dual-layer oxide scale consisting of a loose Fe 2 O 3 and dense Fe 3 O...

Design of a Shielded Microstrip-Line Diplexer Capable of DC Signal Transmission

This paper proposes a shielded microstrip-line diplexer capable of DC signal transmission between all ports. To secure DC transmission paths, a continuous signal-line structure connecting all ports is employed. In addition, the circuit is configured only with transmission lines a...

Electrical Characteristics of Lead Lanthanum Zirconate Titanate Capacitors

Capacitors in DC-link applications for solar power systems should maintain stable electrical characteristics under high voltage and high switching frequency conditions. Recently, lead lanthanum zirconate titanate (PLZT) capacitors have attracted attention due to their high dielec...

A review of comparative studies on injection strategies of spark ignition internal combustion engines with ammonia-hydrogen blends

Ammonia-hydrogen fuels are promising for low-carbon spark-ignition (SI) engines, but their performance strongly depends on fuel-delivery and combustion-control strategy. This review compares port fuel injection (PFI), direct injection (DI), PFI + DI, ammonia-hydrogen dual direct...

Razvoj i implementacija aplikacije za mjerenje opsega pokreta korištenjem računalnog vida

Mjerenje opsega pokreta ključno je u fizioterapiji. Cilj je evaluirati autorsku aplikaciju (MediaPipe) za bezmarkersko mjerenje kinematike u usporedbi s goniometrom. Mjereno je 5 pokreta na 3 ispitanika. Aplikacija pokazuje visoku točnost za pokrete abdukcije ramena i retrofleksi...

Field-informed thermo-mechanical modelling of a full-scale energy quay wall

Energy quay walls (EQWs) represent an emerging class of energy geostructures that combine geothermal heat exchange with retaining-wall functions along waterways. While their thermal performance has been investigated in several recent studies, their thermo-mechanical (TM) behaviou...

Thermal Impact of Under-Line Fires on MVDC Overhead Conductors and Clearance Distance Analysis

As MVDC systems expand along roadways, overhead conductors face fire hazards from under-line vehicles and containers. Using FDS 6.9.1, this study evaluates thermal responses of an ACSR-OC 160 mm² XLPE-insulated conductor for seven scenarios — passenger car, two cars, van, bus, st...

Interpretable machine learning model for analyzing the effect of building characteristics on cost with Extreme Gradient Boosting and Shapley Additive Explanations

A building consists of many components, each with its own financial impact. A clear evaluation of these impacts is possible through the analysis of the components that make up construction costs. This study aims to evaluate and interpret the combined use of construction cost comp...

Differential effects of Qingre Lishi formula on serum total bile acid and liver function markers in early- and late-onset intrahepatic cholestasis of pregnancy

This study aimed to explore the differential intervention effect of Qingre Lishi formula on serum total bile acid and liver function markers in patients with early-onset and late-onset intrahepatic cholestasis of pregnancy (ICP), and to provide a basis for clinical classification...

Polling Without People: Can Silicon Samples of CASM-Inspired LLM Personae Mimic Human Respondents in Pre-Election Polling?

We introduce a framework for simulating pre-election survey responses with large language model (LLM) synthetic personae.Drawing on the Cognitive Aspects of Survey Methodology (CASM) literature, our approach combines synthetic biographies, salient-event memories and conditional n...

Development of a Safety Assessment Framework for Fixed-Type Offshore Wind Power Facilities Using AHP-FMEA Methodology

Fixed-type offshore wind power facilities operate under harsh marine conditions—salinity, corrosion, combined wave and current loading, and severe access restrictions—that increase the likelihood of component failure while making periodic inspection and maintenance difficult and...
