Weed control is a basic agricultural practice, typically achieved through herbicides and mechanical weeders. Because of the negative environmental impacts these tools, alternative solutions are being developed adopted worldwide. Following recent technical developments, an autonomous laser-based weeding system (ALWS) now offers possible solution for sustainable weed control. However, beyond proof performance, little known about adoption potential such system. This study assesses ALWS, using...

Purpose This study aims to investigate the impact of consumer ethnocentrism on consumers' evaluation blockchain-based traceability information. It also examined how use quick response (QR) codes for affects traceable food products. Design/methodology/approach An online choice experiment was conducted determine Feta cheese with a quota sample 715 Greek consumers. Pearson bivariate correlation and mean comparison were used examine relationship between QR behaviour. Random parameter logit...

Abstract Purpose Challenges in sustainable development envisioned the European Union for agricultural sector require innovation to raise efficiency of production and safety farming processes farmers ensure food consumers. One key productivity factors plant is effective weeding. The WeLASER project aimed develop a high-power autonomous vehicle with lasers control weeds. To be sustainable, invention should have high environmental performance whole life cycle perspective, including its...

The growing concern for food safety and quality motivates governments private sectors to improve consumers' confidence in systems, such as through adopting certifications traceability systems. recent emergence of diverse labelling schemes the turbulence systems emerging countries have sparked questions about valuation labels. Nonetheless, little is known on how familiarity with, trust knowledge these affect willingness pay market contexts. This study aims address literature gaps by...

feta cheese is a Greek protected designation of origin (PDO) product that produced in three main phases: milk collection, preparation and maturation, packaging. Each phase must be aligned with quantitative rules, stemming from the legislation framework best practices. The production complexity, increased cost, centralised monolithic traceability systems, lack systematic monitoring have made dairy products commodity frequency food fraud. Given context section Greece, this study aims to...

Summary This study examined three collaborative scenarios for the implementation of a high‐level aseptic filling machine in small‐scale food processing improved safety short supply chains. A two‐stage research design was implemented, based on an exploration and evaluation phase. Two workshops were organised to conceptualise following scenarios: mobile packaging, cooperative individual ownership. novel approach strengths, weaknesses, opportunities threats‐analytical hierarchy process...

Beta-carotene is a terpenoid pigment that highly valuable due to its nutritional benefit as precursor of vitamin A and antioxidant properties. marine green alga Dunaliella salina well known for high carotene, with above 95% β-carotene, under growth-limiting conditions. Carotene contents are different among D. strains culture Selecting strain carotene amount mass cultivation crucial. Hence, this study aimed select candidate production. Analysis total capacities from 8 local isolated (A9, A10,...

Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. Several strains local salina were isolated. Together with bardawil DCCBC 15 and CCAP 19/18, examined for their growth under effects salinities (1 M, 1.5 M 2 M) light intensities (50, 100 150 µmol photon/m2/s). The result showed optimal was obtained at 50 photon /m2/s intensity. Data this study will be further applied carotenogenic induction experiments using salinity stresses on these strains.

Beta-carotene is a valuable carotenoid in high demand as natural food coloring agent, provitamin A, additive to cosmetics, and health food. It can be accumulated up more than 10% of cellular dry weight Dunaliella salina under carotenogenic conditions such irradiance, temperature, salt concentration nutrient deficiency. High beta-carotene productivity best achieved two-phase culture system through biomass optimization induction. A low-cost enriched seawater medium (MD4) was previously...

The article aims to analyze the impact of foreign direct investment on export activities countries around world when considering role exchange rates and accession World Trade Organization (WTO). Bayesian method is used process data from 40 in period 1995- 2021, including 20 belonging WTO not WTO. Research results show that FDI has a positive countries' exports, especially for have joined country's real rate decreases. Besides, inflation rate, GDP growth trade openness an increasing exports....

Trong nghiên cứu này, polycaprolactone triol (stPCL) hình sao đã được tổng hợp thành công thông qua phản ứng trùng mở vòng của ε-caprolactone (CL), sử dụng glycerol làm chất khởi đầu và Sn(Ot)2 xúc tác. Khối lượng phân tử stPCL xác định bằng phương pháp sắc ký gel (GPC,) nằm trong khoảng 1.600Da. Cấu trúc phổ cộng hưởng từ hạt nhân (1H-NMR) quang hồng ngoại biến đổi Fourier (FTIR). Sản phẩm này nguyên liệu chính để polyurethane (PU) nhiệt rắn hướng lĩnh vực y sinh.

Abstract Background Dietitians play a critical role in the public's relationship with food and are often overlooked as an important stakeholder group general debate about sustainable food. Genetically modified organisms (GMOs) one type of modern source that could contribute to more system. This case study is first examine knowledge, perception willingness‐to‐recommend (WTR) genetically (GM) foods by dietitians Europe. Methods An online survey was addressed all members Flemish Association...

Ho gà là một trong năm bệnh gây tử vong cao nhất ở trẻ em, đặc biệt < 6 tháng tuổi. Hiện nay bắt đầu được tiêm vắc xin phòng ho từ 2 tuổi, vì vậy xuất hiện “Chiến lược bảo vệ dạng tổ kén”. Trong thời điểm đại dịch COVID-19 tại Việt Nam có những cần trên phụ nữ mang thai và khác.
