Research Progress And Application Of Walnut Shell-Breaking And Kernel Extraction Technologies, Lu Shaomin, Li Wei, Liao Hongsen, Jiang Chenxi, Huang Shengyang

Food and Machinery

Walnut, characterized by its high nutritional value and substantial market demand, has become a globally significant economic crop. However, the intrinsic hardness of the shell and its tight adhesion to the kernel pose considerable challenges to efficient shell breaking and kernel extraction, making this process a critical bottleneck in industrial production. The walnut shell -breaking and kernel extraction process generally encompasses two fundamental stages:shell fragmentation and subsequent shell -kernel separation. This paper systematically reviews the current state of walnut shell -breaking and kernel extraction technologies and analyzes the advantages and limitations of conventional manual and mechanical shell -breaking methods, alongside …

Translational Design Of Yingdu Baba Lantern In Southern Fujian Gongtang Packaging From The Perspective Of Cultural Genes, Liu Yun, Huang Ying

Food and Machinery

To address current issues of insufficient cultural expression and design homogenization in the packaging design of intangible cultural heritage (ICH) foods in the southern Fujian region, this study takes the Yingdu Baba lantern, a national -level ICH item, as the research subject and Gongtang packaging design as the practical carrier. By introducing cultural gene theory, the core cultural factors of the Yingdu Baba lantern are identified and extracted from six dimensions:form, color, pattern, material, behavior, and semantics. A translation framework between cultural genes and packaging design elements is constructed, and corresponding design strategies are proposed. The framework is validated through …

Semantic System Construction And Visual Translation Of Hongshan Jade Culture In Food Packaging Design, Liu Yajuan, Ma Shiyu, Wang Xinyuan

Food and Machinery

With Hongshan jade culture as the core semantic resource, this study investigates the systematic semantic construction and visual expression paths of Hongshan jade culture in contemporary food packaging design. First, the foundation for extracting visual morphemes of Hongshan jade culture is established from three dimensions:cultural semantic structure, aesthetic characteristics, and digital technology support. On this basis, a five -stage semantic system encompassing "semantic extraction, form clustering, semantic reproduction, semantic refinement, and semantic imaging" is developed, through which the visual texts, behavioral texts, and spiritual texts of typical jade artifacts are distilled to achieve the visualized expression of cultural morphemes. Furthermore, …

Homogenization Dilemma And Corresponding Strategies Of Emotional Interaction In Digital Food Packaging Design, Zhao Chunyan

Food and Machinery

Currently, emotional interaction in digital food packaging design is increasingly homogenized, mainly manifested in the mechanical replication and sensory stacking of interactive forms, the superficial decoration and semantic vacuum of cultural symbols, and the fragmentation of user experience processes and emotional gaps. The reasons lie in design thinking that overly prioritizes a technology -centered orientation while failing to adequately embody emotional purposes, cultural symbols that remain at the level of appropriation rather than translation, and the neglect of the structural nature of the five elements of user experience. Grounded in foundational theories of design studies, this paper achieves closed -loop …

Kronik Perubahan Paradigma Terhadap Wacana Agronomi Di Andalusia Pada Abad Ke 11-12 M, Muhamad Naufal Sulistyo

Multikultura

This study examines the history of Islamic science through the paradigmatic shift in agronomic discourse (filāḥah) in Andalusia during the 11th to 12th centuries CE. Employing Thomas Kuhn's paradigm shift theory within his framework of Scientific Revolution, this qualitative research aims to reconstruct the intellectual transformation of the Muslim agronomist community from a magical-speculative orientation toward an empirical-technical one. The study applies a five-stage historical research method topic selection, heuristics, verification, interpretation, and historiography in conjunction with the paradigm shift concept, as applied to the major agricultural treatises of Andalusia.

Part Ii: Sustainable Irrigation Practices For Cut Flowers, Chloe Seeborg, Melanie Stock, Burdette Barker, Alex Rodriguez, Jonathan D. Meyer

All Current Publications

Sustainable irrigation uses crop and environmental information to guide the frequency (how often) and amount (how much) of water to apply. Without this balance, poor irrigation practices can result, causing crop stress from too little or too much water, nutrient loss and contamination, or wasted water that drains below the root zone. This fact sheet covers the basics of soil water storage, crop water demand, considerations for designating irrigation zones, using free weather stations, and water conservation strategies for gardens and small farms, with a focus on cut flowers.

Comparing Soil Health Indicators Between Corn-Soy Production And Restored Utility-Prairie Systems, Katie Oakley Anthony

Scholars Week

It has long been known that cultivation in agroecological systems disrupts inherent soil attributes that support soil health. Soil health can be defined as the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans – but is soil health a blanket concept? This research intended to address health gaps in production systems – corn-soy rotation (CS) and restored utility-prairie (UP) – based on USDA taxonomic classifications. The quality of soil is generally reported in terms of physicochemical and biological indicators. By examining same soil series in adjacent land management systems, those indicators …

Elizabeth Heine and Dr. Iin Handayani, Ph.D. Murray State University, Hutson College of Agriculture

Abstract

Soil quality influences agricultural productivity, water retention, nutrient cycling, and environmental sustainability. Soil organic matter (SOM), soil water at field capacity (SWFC), macroporosity, and total porosity are important indicators of soil health because they affect soil structure, aeration, and water availability. This study evaluated these properties under different land-use systems at the West Farm Complex in Calloway County, Kentucky. Soil samples were collected from corn, soybean, sunflower, tobacco, pasture, and miscanthus fields; 24 disturbed and 24 …
