A preliminary investigation into the enhancement of cheese with grape skin powder
No full textImproving management and making the food industry more sustainable requires a focus on reducing waste and finding uses for by-products. In the case of grapes, by-products account for approximately 20%. It is worth noting that these by-products contain beneficial phenolic compounds that have anti-allergenic, antibacterial, anti-carcinogenic, anti-inflammatory, antioxidant, and cardioprotective effects. For these reasons, the food industry sector must turn its attention to them and use them as functional ingredients. In this study, grape skin powder (GSP) was added to cheese to increase its antioxidant and bioactive compounds content. The enriched cheese contained significantly higher levels of total phenolic content (TPC) and antioxidant activity compared to the control sample. Adding 2% grape skin powder resulted in an increase of 1.927 mg GAE/g DW (mg gallic acid equivalents (GAE) per gram of dry weight (DW)) of TPC in cheese formulation. The GSP-supplemented cheese also showed greater antioxidant activity than the control. This study demonstrates that grape by-products can effectively transfer beneficial compounds to cheese
Transfer of heavy metals in soil in-plum cultivation: a field study in Adamachi Iasi, Romania
No full textCurrently, global environmental concerns about heavy metal pollution are driven by rapid urbanization and industrial development. Therefore, a field study was conducted to assess the concentration of heavy metals (Pb, Co, Zn, Ni and Cu) in orchard soils and its transfer to two plum varieties (Stanley and Anna Späth) at Adamachi Farm – Iasi University of Life Sciences (IULS). In addition, heavy metal transfer (MTF), daily metals intake (DIM) and the index of health risk (HRI) were evaluated. The concentration of Pb, Co, Zn, Ni and Cu in soil and plum leaves samples were analyzed using atomic absorption spectrometry after acid digestion with a mixture of HNO3 (65%), HCl (37%) and HClO4 (60%). Metal concentration patterns occurred as follows 130.65>76.6>30.36> 21.69>13.26 mg/kg for Cu, Zn, Ni, Pb and Co in soil samples and 20.16>10.00> 2.10>1.68 mg/kg for Zn, Cu, Ni and Pb in plum leaves, while Co residue was not detected. The maximum heavy metal concentrations were found at the soil surface (0 – 30 cm depth) due to soil organo-mineral content and antifungal treatments. The health risk index predicted (HRI) for adults as well as children was in the sequence Pb > Cu > Ni > Zn, suggesting no health risk with values that did not exceed the safe limit (1). Therefore, it is essential to manage the causes and sources of heavy metal transfer prudently and effectively in order to prevent environmental contamination
Septicemic Outbreak in A Rainbow Trout Intensive Aquaculture System: Clinical Finds, Etiological Agents, and Predisposing Factors
No full textOn the 23rd of September 2022, a small intensive aquaculture unit populated with rainbow trout (Oncorhynchus mykiss) reported increased mortality in adults and juvenile fish. The unit comprised 12 enclosed concrete basins with a capacity of ten cubic meters of water, populated with 150 kg of fish each. Fish were subjected to a clinical examination on the site, after which whole fish were harvested for a bacteriological and histopathological examination. Water quality parameters were examined using classic biochemical methods and Fourier Transform Infrared Spectroscopy in order to find out whether the environment in which the fish live is also a predisposing factor that could facilitate different pathogens and induce a state of disease in the fish. Real-time PCR was performed on strains of Aeromonas spp. sampled from the fish to accurately identify the pathogen species. The goal was to accurately identify the problems and predisposing factors that lead to disease outbreaks
Redefinirea spațiilor interioare post-covid: principii de design ergonomic pentru integrarea plantelor
Get PDFIn the wake of the COVID-19 pandemic, the
significance of interior spaces has been redefined,
emphasizing comfort and well-being more than ever. This
review explores the integration of plants within these spaces,
drawing from ergonomic design principles. As the pandemic
highlighted the importance of mental and physical health,
plants have emerged as aesthetic assets and functional
contributors to our living spaces. This review examines the
role of plants in enhancing mental well-being, the ergonomics
of plant-focused design, their contribution to indoor air
quality, and their alignment with post-pandemic design trends.
The insights provided herein guide the reimagining of interior
spaces for a post-pandemic er
Beneficiile amenajărilor peisagere pentru activitățile școlare și de recreere în aer liber: studii de caz și propuneri de amenajare
Get PDFIn the post-pandemic context, when people have
developed a heightened awareness of their relationship with
their environment, this study addresses the impact of
landscaping on school and outdoor recreation activities. By
analyzing three relevant case studies from the literature, the
paper highlights the benefits of outdoor classrooms and how
they can improve student engagement and well-being. In light of
these findings, two proposals for the design of the green space
of the "Vasile Adamachi" Agricultural College of Food Industry
in Iasi were developed. These proposals aim to create an
environment conducive to learning and recreation, integrating
natural elements and facilities adapted to the needs of students
Tailored management plan for preventing viral diseases within dog shelters
Get PDFDog shelters play a crucial role in animal welfare by providing temporary care and finding permanent homes for
homeless dogs. However, the close confinement and high turnover of animals in shelters create an ideal environment for
the spread of viral diseases. To combat this, various preventive measures have been implemented, but a comprehensive
and tailored approach is essential to effectively safeguard the health of shelter dogs. This study outlines a tailor-fit
management plan that incorporates a multifaceted approach, encompassing vaccination, testing, hygienic practices, and
quarantine protocols, to effectively prevent viral diseases within dog shelters
Pilot study regarding reproduction and growth in Saint Bernard and Caucasian Shepherds dog breeds
Get PDFThis retrospective, observational, descriptive study includes two large dog breeds, the Caucasian Shepherd breed and
the Saint Bernard breed belonging to a kennel in Romania, and was carried out for three consecutive years, to improve
breeding practices and obtain canine specimens according to the international FCI recognized standards. The fertility,
fecundity and prolificacy, stillbirth, survival at 28 days, the average daily gain and weekly growth rate were recorded
and compared
Peculiarities of the masticatory apparatus of guinea pigs (Cavia porcellus)
No full textGuinea pigs (Cavia porcellus)
are rodents that feed on grassy plants, buds
and sprouts, with cheek teeth having
specialised abrasive surfaces for plant
grinding. In analysing the prehension and
trituration ways of guinea pigs, many
differences concerning mandible
conformation, the positioning of cheek teeth
and the morphology of the masticatory
muscles compared to other rodents were
found. Masticatory muscles of guinea pigs
are predominant compared to the mimetic
muscles which are reduced. Compared to
other rodents, in guinea pigs, inside the
tendon thickness of the superficial part of the
masseter muscle there are two rounded
cartilaginous structures such as sesamoids.
The dorsal one is larger, measuring about 3–
4 mm in diameter having the role of
reducing pressure on the tendon when it
passes over the mandible ridge. The other is
ventrally placed, about 2–3 mm in size and
protects the tendon of the superficial part of
the masseter muscle when it passes over the
ventral tubercle of the mandible
