Effect of the grape seed proanthocyanidin extract on the free radical and energy metabolism indicators during the movement
In order to explore the mechanism of grape seed proanthocyanidin extract (GSPE) against exercise-induced fatigue, the mice movement model was used, and the free radical and energy metabolism indicators during movement were measured. The results show that grape seed proanthocyanidin extract can improve the activity of antioxidant enzymes such as SOD and GSH-Px in the liver in exercised mice, and lower the MDA content,...

Engineering properties of improved fibrous peat
Depending on the soil type, different types of binder have been used to stabilize soft soils nowadays. An essential criterion in the selection of suitable binder is its capability of achieving the desirable soil stabilizing function. For peat soil, it was evident that the engineering properties of the soil can be improved with Portland cement and ground granulated blast furnace slag with siliceous sand acting...

Urban flora and ecological characteristics of the Kartal District (Istanbul): A contribution to urban ecology in Turkey
For years, ecologists who have been trying to understand the relationship between the organisms with each other and/or their environments, have carried out their researches sometimes far from civilization, sometimes on a desolate island or in a tropical rainforest. Today, about half of the world’s population lives in urban areas. Therefore, most of the ecological problems have been brought to these areas....

Bacterial contamination of lettuce and associated risk factors at production sites, markets and street food restaurants in urban and peri-urban Kumasi, Ghana
There is increasing evidence that urban grown vegetables in developing countries can be contaminated with pathogenic microorganisms. This is particularly true when wastewater is used in irrigation. The microbiological quality of wastewater grown lettuce on farms, markets and at street food vendor sites were evaluated for thermotolerant coliforms, enterococci and Salmonella using standard methods. Farm...

Effects of holes placed on perforated finned heat exchangers at different angles on the Nusselt and Reynolds numbers
In this study, 6 mm diameter holes were opened on each circular fin on a heating tube in order to increase convective heat transfer. This is different from other studies in the literature. These holes were placed on the circular fins in such a way as to follow each other at the same chosen angle. The holes created turbulence in a region near the heating tube surface on the bottom of the fin. Experiments were performed...
