Structure of the out- flows behind buildings and Influence of the geometry of the streets on the out-flows

This paper intends to study the latest results from the research methods available with special intentions given to the architectural effects of the street valley and wind speed. Extensive research has been carried out through several research approaches to understand the effect of wind flow formation in the streets and the current wind condition on the structure of the wind current. The main goal of this paper is to study the structure of out- flows of buildings and the effect of street engineering on external flows. The numerical modeling is to simulate the effect of the wind flow and the layer limit on different building structures using the ANSYS Fluent package. The program was based on the K-ε model to incorporate the potential of differential equations forming the mathematical model. Three cases were considered; the first case is the height-to-width ratio of the valley (h/w), the second is the width of the dome (b3/b) and the third case the ratio of the height of the valley (h3/h) to see the effect of street valley engineering and wind speed effect

Koncentracija teških metala u tkivu oslića Merluccius merluccius (Linnaeus, 1758) iz Oranskog zaljeva (Sredozemno more): procjena potencijalnog rizika za ljudsko zdravlje

To evaluate the potential human health risk to hake consumers, the bioaccumulation of heavy metals (Cd, Pb, and Zn) was measured in the edible tissues of hake Merluccius merluccius (Linnaeus, 1758) caught from Oran Bay on the western Algerian Mediterranean coast. Results revealed that the average metal concentrations varied significantly among sex and in target organs. The concentrations of metal accumulation take place preferentially in the liver compared to the muscle of hake species, with the highest levels found for Zn, followed by Pb and Cd. The Estimated daily intake (EDI) of each trace metal did not exceed the tolerable daily intake (TDI). Human health risk assessment from heavy metal exposure through fish consumption from Oran Bay for adults showed no significant non-carcinogenic adverse health risk since all calculated values for Target Hazard Quotient (THQ) and Total Target Hazard Quotient (TTHQ) were <1.Da bi se odredio potencijalni rizik za ljudsko zdravlje pri konzumaciji oslića, određena je bioakumulacija teških metala (Cd, Pb i Zn) u jestivom tkivu oslića Merluccius merluccius (Linnaeus, 1758) ulovljenog u zapadnom Sredozemlju u alžirskom zaljevu Oran. Rezultati pokazuju da prosječne koncentracije metala značajno variraju ovisno o spolu i testiranom organu oslića. Metali se više akumuliraju u jetri oslića nego u mišićima, a najviše razine utvrđene su za cink, nakon čega slijede olovo i kadmij. Procijenjeni dnevni unos (eng. Estimated daily intake, EDI) svakog metala nije premašio prihvatljivi dnevni unos (eng. Tolerable daily intake, TDI). Procjena rizika za ljudsko zdravlje zbog izloženosti teškim metalima pri konzumaciji ribe iz zaljeva Oran pokazala je da za odrasle osobe nema značajnog nekancerogenog ali štetnog zdravstvenog rizika jer su sve izračunate vrijednosti za kvocijent ciljane opasnosti (eng. Target hazard quotient, THQ) i ukupni kvocijent ciljane opasnosti (eng. Total target hazard quotient, TTHQ) bile <1

In vivo antidiabetic effect and antioxidant potential of Stevia Rebaudiana mixed with Tragacanth gum in orange nectar

The objective of this research was to develop a novel low-sugar orange nectar using Stevia Rebaudiana and tragacanth gum, aiming to enhance the anti-hyperglycemic effect and antioxidant stability. The experimental design involved varying two levels of Stevia and tragacanth gum, including central points. The oxidative stability and organoleptic test were required for the selection. The impact of daily consumption of the optimal nectar on postprandial glycemia was assessed in diabetic Wistar rats.The results demonstrated that formulation F1, containing 0.5% tragacanth and 0.03% Stevia, achieved the highest organoleptic score (9.55) and exhibited the greatest stability, with half-life times of 83.87 days at 4 °C and 76.26 days at 25 °C. The in-vivo antidiabetic study revealed a positive effect of this formulation in preventing postprandial hyperglycemia and weight gain. This research clearly highlights the importance of incorporating 0.03% Stevia and 0.5% tragacanth in the formulation of low-sugar orange nectar to ensure functional efficacy and technological stability
