Ülkemizin deprem kuşağında bulunması ve enerji maliyetlerinin sürekli olarak artması, inşaat teknolojilerinin gelişmesinde itici bir güç olmuştur. Bu gelişmelerin başında hafif yapı malzemelerinin üretilmesi çeşitli teknik özelliklerinin iyileştirilmesi gelmektedir. Bina ölü yükünün azaltılması, ısı ses yalıtımı gibi özellikleri nedeniyle doğal agregalar son çeyrek yüzyılda oldukça fazla kullan...

This study examined the effect of adding antioxidants, namely curry leaf extract (CLE) and butylated hydroxyanisole (BHA), on physicochemical properties ghee during deep frying. The results showed that addition CLE to resulted in significant changes L*, a*, b* values, likely due extraction chlorophyll molecules preparation. Deep frying caused a decrease L* values an increase a* ghee, as well re...

OBJECTIVE To determine if a causal connection exists between food additives and various medical complaints. DESIGN Literature study. METHOD Medline over the period January 1966-January 1999 was searched for articles on the following substances not containing protein and lactose: monosodium glutamate (MSG), sulfites, azo-dyes (tartrazine, sunset yellow, azorubin, amarant, cochineal red), ben...

In this study, antioxidative activities of aqueous extract of Biarum bovei (BBE) in stabilizing of canola oil during storage at 20°C was evaluated. For this purpose, the total phenolic (TP), flavonoids (TFC), and tocopherol content (TTC) of the extract were determined and β-carotene bleaching system was used to assess the antioxidant efficacy of BBE. The amount of TP, TFC, and TTC in BBE indica...

Nitrite-free and low-nitrite meat-curing systems were developed to eliminate or reduce nitrite in frankfurter-type sausages. Different composite meat-curing mixtures were formulated using cochineal and paprika as natural colorants, sodium hypophosphite (SHP) as antimicrobial agent, butylated hydroxyanisole (BHA) as antioxidant and sodium nitrite. The treatment, which contained 0.015% cochineal,...

The electrophysiological mechanisms underlying working memory maintenance of information in the ventral and dorsal visual stream (VVS, DVS) remain elusive. Here we used electrocorticography recordings covering VVS, DVS and prefrontal cortex (PFC) in epilepsy patients while they were performing a delayed match-to-sample task. The experimental conditions (face identity, orientation) were designed...

We examined t-butylhydroquinone (t-BHQ) and t-butylquinone (t-BuQ), two of the major microsomal metabolites of the synthetic antioxidant butylated hydroxyanisole (BHA), for their ability to react with the xenobiotic arylamines aniline and N-methylaniline. A number of substances were isolated by thin-layer chromatography. The main products were quantitatively evaluated and their structures assig...

For most of the rigid manipulators, it is possible to apply a gravity compensation mode, by which the user is able to easily reconfigure the arm and record the necessary data. However, due to the specific characteristics of soft robots such as elastic properties and complex dynamics, it is usually very difficult to implement kinesthetic teaching for Learning from Demonstration (LfD) scenarios. ...

Transmission congestion is the major challenge in the operation of competitive power market. Sufficient transmission corridor is necessary for realization of power transaction. This paper proposes an efficient approach for transmission congestion management using the Black Hole Algorithm (BHA). Congestion is relieved by rescheduling of real power from the market clearing schedule. BHA is a rece...

Fresh ground beef patties with (1) no antioxidant (control), (2) 0.02% butylated hydroxyanisole/butylated hydroxytoluene (BHA/BHT), (3) 3% dried plum puree, or (4) 0.25% rosemary extract were aerobically packaged, irradiated at target doses of 0, 1.5, or 2.0 kGy (1.7 and 2.3 kGy actual doses), and stored at 4°C. The samples were evaluated for lipid oxidation on 0, 3, 7, 14, 21, and 28 days of s...
