Surgical treatment of traumatic injuries of land turtles
No full textTortoises belong to the order Testudines, and their shell, composed of the carapace and plastron, protects internal organs and represents a unique evolutionary adaptation. The shell is a rigid structure of bony plates connected to the spine and ribs, requiring a specific approach to diagnosing and treating injuries. The most common injuries in terrestrial tortoises include traffic accidents, dog bites, and thermal injuries. Shell fractures can be simple or complex and are often accompanied by injuries to internal organs. Diagnostic procedures rely on imaging methods such as radiography, CT scans, and ultrasound, while laboratory analyses assess the general health status. Surgical treatment methods include wound management with thorough irrigation using sterile solutions, debridement of necrotic tissue, and application of antimicrobial agents. Shell fixation is performed using techniques such as screws, wires, epoxy, and bone plates, ensuring fracture stability and protection of internal structures. Vacuum therapy accelerates healing and reduces recovery time, especially for wounds with significant tissue loss. Limb fracture stabilisation involves external fixators, intramedullary pins, and special mini-plates, tailored to the specific fracture types. A combination of techniques is used to maximise stability in complex fractures and improve the healing process. Each phase of treatment, from initial stabilisation to final postoperative care, is crucial for the successful recovery and preservation of functionality in terrestrial tortoises. Special attention is given to adapting environmental conditions, including optimal temperature and humidity, to ensure tissue regeneration and overall health. This review aims to describe the specific anatomy of the land turtles, the most common injuries, methods of diagnosing injuries, and surgical treatment techniques depending on the type of injury
Dodatak pulpe bobičastog voća u probiotički jogurt: Mikrobiološka, teksturalna i senzorska svojstva te antioksidacijska aktivnost
No full textThe effect of different berry fruits on the bacterial survival, antioxidant, textural, and sensory characteristics of probiotic yoghurt containing Lactobacillus acidophilus LA-5, and Bifidobacterium animalis subsp. lactis BB-12® was investigated during 21 days of storage. In this context, raspberry (Rubus idaeus), goji berry (Lycium barbarum), or blueberry (Vaccinium corymbosum) pulp (15 %) containing fruit and sugar in a 1:1 ratio was used in the yoghurt manufacture. Yoghurt without any fruit pulp was the control sample. The viable cell counts of yoghurt starter bacteria and probiotic bacteria were above 7.50 and 8.70 log CFU/g, respectively, meeting the recommended minimum levels. The highest viability of L. acidophilus was in goji berry-added yoghurt for 14 days of storage. In contrast, the superiority of goji berries for the viable count of B. lactis could be determined only on the 14th and 21st days. Goji berry-supplemented probiotic yoghurt showed the highest total phenolic content and (2,2-diphenyl-1-picrylhydrazyl) radical (DPPH˙) scavenging activity throughout the storage. Yoghurt containing blueberry pulp had a higher anthocyanin amount than the sample with raspberry during storage. In contrast, anthocyanin, in terms of the pelargonidin-3-glycoside, could not be determined in probiotic yoghurt with goji berry pulp. The supplementation of probiotic yoghurt with berry pulp improved the viscosity and water-holding capacity properties; however, it had generally no significant effect on the sensory characteristics.Ispitan je učinak različitih bobičastih plodova na preživljavanje bakterija, antioksidacijska, teksturalna i senzorska svojstva probiotičkog jogurta koji sadrži Lactobacillus acidophilus LA-5 i Bifidobacterium animalis subsp. lactis BB-12® tijekom 21 dana skladištenja. U tu svrhu u proizvodnji jogurta korištena je pulpa maline (Rubus idaeus), goji bobice (Lycium barbarum) ili borovnice (Vaccinium corymbosum) (15 %) s omjerom voća i šećera 1:1. Jogurt bez dodatka voćne pulpe korišten je kao kontrolni uzorak. Broj živih stanica starter kultura jogurta i probiotičkih bakterija bio je iznad 7,50, odnosno 8,70 log CFU/g, što zadovoljava preporučene minimalne razine. Najveća održivost L. acidophilus zabilježena je u jogurtu s dodatkom goji bobica tijekom 14 dana skladištenja. Suprotno tome, prednost goji bobica u održavanju broja živih stanica B. lactis uočena je samo 14. i 21. dan. Probiotički jogurt s dodatkom goji bobica pokazao je najviši ukupni sadržaj fenola i najjaču aktivnost uklanjanja DPPH˙ radikala tijekom skladištenja. Jogurt s pulpom borovnice imao je veći sadržaj antocijana u usporedbi s uzorkom s malinom tijekom skladištenja. S druge strane, antocijanini u obliku pelargonidin-3-glikozida nisu utvrđeni u probiotičkom jogurtu s pulpom goji bobica. Dodavanje pulpe bobičastog voća poboljšalo je viskoznost i sposobnost zadržavanja vode u probiotičkom jogurtu, no općenito nije imalo značajan utjecaj na senzorska svojstva
Embedded Carbon Declaration on transformer nameplates: Towards transparency and accountability in transformer sustainability
Get PDFTransformer nameplates reveal electrical identity, but not the carbon footprint of the product itself. This article argues for adding an Embedded Carbon Declaration (ECD) that reports cradle-to-gate emissions and links to verified LCA/EPD data via QR code. As grids decarbonize, this metric becomes essential for procurement, Scope 3 accounting, and real sustainability leadership
Grid operators in the age of autonomous energy systems: How smart grids will transform daily operations – AI article rejected: Experiment in autonomous scientific writing
Get PDFThis article documents an attempted experiment in generating a technical paper entirely by means of Artificial Intelligence (AI). The author set out to test the boundaries of AI in technical writing and submitted the article to peer review for Switchgear Magazine. In accord with the normal double-blind process, he did not disclose the article’s non-human origin. The journey through this process revealed both the capabilities and limitations of current AI systems.The author uncovered patterns in how AI systems approach technical writing and where they fall short of professional standards, namely, peer review detected an artificial voice
