Computational fluid dynamics (CFD) simulations have been extensively used in designing air distribution systems for controlled environment agriculture (CEA).In recent years, more application studies using CFD can be found vertical farms due to the increasing interest indoor farming systems.However, it is well-known that are sensitive many computational parameters and settings.The requirement of a crop response model simulation farm makes even complicated.Despite increased interest,...

Introduction This study investigates the quality of air temperature data collected from a small-scale Controlled Environment Agriculture (CEA) system using low-cost IoT sensors during lettuce cultivation at four different temperatures. Ensuring in CEA systems is essential, as it affects stability and operational efficiency. research aims to assess by analyzing correlation between cumulative agricultural operations (Agr.Ops) variability. Methods The methodology involved collecting throughout...

Seven isonitrogenous and isolipidic diets containing fish meal (FM) protein replaced by corn gluten (CGM) at 0% (the control, C0), 10% (C10), 20% (C20), 30% (C30), 40% (C40), 50% (C50) 60% (C60) were fed to juvenile Pseudobagrus ussuriensis for 8-weeks evaluate the effects of FM CGM on growth, feed utilization, nitrogen (N) phosphorus (P) excretion IGF-I gene expression P. ussuriensis. The results showed that replacement level up did not affect weight gain, specific growth rate (SGR), intake...

This research aims to explore the performance of ice storage modes in a photovoltaic (PV)-driven refrigerated warehouse. The were concisely clarified into series match (SM) and parallel (PM), which clearly defined theoretically, experimentally economically analysed under various working conditions system configurations. analysis reveals that SM mode demonstrates an enhanced coefficient (COP) no full-load using utility electricity PV power as energy supply, with COP for vapour compression...

Accurate energy consumption modelling is critical for the improvement of efficiency in machining. Existing models machining processes mainly focus on turning or milling, and there are few drilling. However, since drilling often applied to roughing semi-finishing, cutting parameters large, huge, it urgent study during process. In this paper, an model was proposed. Idle power, auxiliary power were included proposed model, using force obtain Further, relationship between analyzed. Cutting...

While hydroponics is considered an efficient vegetable production system, there a compelling need to investigate the efficiency of current generic nutrient dosing recommendation primarily based on electrical conductivity (EC) measurements. Such information critical fine-tune and optimize hydroponic management practices for improved uptake efficiency. This study investigated dynamics some micro macronutrients (N, P, Ca, Mg, K, Fe, Mn) in recirculating film technique (NFT) system under lettuce...

Water source heat pump (WSHP) systems are widely used for cooling and heating due to high efficiency. Accurate modeling of water is the basis performance prediction, design control optimization. However, various uncertainties exist in simulation affect results, which can be categorized into parameter model form uncertainties. Without considering these uncertainties, would overestimated or underestimated then decision stakeholders. The models pumps especially important accurate simulation....

Due to different datum position and inevitable distortion from the linear friction welding process, nominal CAD model design stage is no longer suitable for use of final NC machining, that main problem precisely machining complex blisk. In this paper, an adaptive approach based on process high precision manufacturing blisk proposed developed. Comparing with inspection result, reconstructed describe workpiece localization, allowance distribution composite error compensation accurately....

Avian infectious bronchitis virus (IBV), which is prevalent in many countries causing severe economic loss to the poultry industry, causes (IB) birds. Recombinant single-chain variable fragments (scFvs) have been proven effectively inhibit viruses, both vitro and vivo, they could be a potential diagnostic therapeutic reagent control IB. In this study, six anti-IBV chicken scFvs, ZL.10, ZL.64, ZL.78, ZL.80, ZL.138, ZL.256, were obtained by screening random clones from an immune antibody...
