Zadovoljstvo proizvođača povrća u zaštićenim površinama na području Zadarske županije

U ovom radu ispituje se problematika vezana za proizvodnju povrća u zaštićenim prostorima na području Zadarske županije. Uzgoj povrća u zaštićenim prostorima u posljednje vrijeme doživljava ekspanziju u svijetu, a naročito u područjima koji gravitiraju mediteranskom bazenu. U skladu s tim, rad se bavi mogućnostima koje ima Zadarska županija u proizvodnji povrća u zaštićenim prostorima. Temelj ovog rada je istraživanje koje je vezano za ispitivanje stavova proizvođača povrća u zaštićenim prostorima na području Zadarske županije o prednostima i nedostacima ovakvog načina proizvodnje. Rezultati dobiveni u ovom istraživanju ukazuju na probleme i mogućnosti s kojima se susreću sadašnji i potencijalni uzgajivači povrća u Zadarskoj županiji

Valorization of Material Wastes for Environmental, Energetic and Biomedical Applications

The development of materials from industrial wastes has attracted the attention of the research community for years. A material's physico-chemical characteristics have specific impacts its properties and their application in environmental, energetic, and biomedical areas, such as in pollutant removal; CO2 capture; energy storage; catalytic oxidation and reduction processes; the conversion of biomass to biofuels; and drug delivery. Examples of such materials are activated carbons, clays, and zeolites, among others. The aim of this Special Issue is to collect the recent advances and progresses developed in this field considering valorised materials from industrial wastes and their applications in environmental, energetic, and biomedical areas

Effect of curing conditions and harvesting stage of maturity on Ethiopian onion bulb drying properties

The study was conducted to investigate the impact of curing conditions and harvesting stageson the drying quality of onion bulbs. The onion bulbs (Bombay Red cultivar) were harvested at three harvesting stages (early, optimum, and late maturity) and cured at three different temperatures (30, 40 and 50 oC) and relative humidity (30, 50 and 70%). The results revealed that curing temperature, RH, and maturity stage had significant effects on all measuredattributesexcept total soluble solids

Numerical modelling of additive manufacturing process for stainless steel tension testing samples

Nowadays additive manufacturing (AM) technologies including 3D printing grow rapidly and they are expected to replace conventional subtractive manufacturing technologies to some extents. During a selective laser melting (SLM) process as one of popular AM technologies for metals, large amount of heats is required to melt metal powders, and this leads to distortions and/or shrinkages of additively manufactured parts. It is useful to predict the 3D printed parts to control unwanted distortions and shrinkages before their 3D printing. This study develops a two-phase numerical modelling and simulation process of AM process for 17-4PH stainless steel and it considers the importance of post-processing and the need for calibration to achieve a high-quality printing at the end. By using this proposed AM modelling and simulation process, optimal process parameters, material properties, and topology can be obtained to ensure a part 3D printed successfully

Numerical Study of Concrete

Concrete is one of the most widely used construction material in the word today. The research in concrete follows the environment impact, economy, population and advanced technology. This special issue presents the recent numerical study for research in concrete. The research topic includes the finite element analysis, digital concrete, reinforcement technique without rebars and 3D printing
