Heavy analysis was carried out at Riau KLHK Laboratory with Atomic Abortion Spectrophotometer Shimadzu AA-7000. The results showed that Pb (14,454 µg/g), Cu (103,778 (111,611 µg/g). highest found Station II (16.0388 i V (170.2445 and Zn (128.7621 In general calculations Provisional Tolerabl...

The deformation behavior of capillary porous (CP) Ni and CP Ti is examined under uniaxial compression in air, water, ethanol. metals contained inert liquids such as H20 C2H5OH are used the heat pipes' active elements space applications. samples for mechanical testing were isostatic compacting vacuum annealing (porosity 60%). Uniaxial tests carried out ethanol Shimadzu AG-50K XD (traverse rate 0...

Bu çalışmada, tahribatsız test yöntemlerinden birisi olan stres dalga yöntemi kullanılarak belirlenen dinamik elastikiyet modülü ile TS ISO 13061-2 (2021) standardına göre statik arasındaki ilişkiyi incelenmiştir. kapsamda rastgele seçilmiş 12x13x110 cm3 boyutlarındaki kayın (Fagus orientalis Lipsky) keresteler kullanılmıştır. Kerestelerin radyal ve boyuna yöndeki uçuş süreleri, 1 μs hassasiyet...

In this study, gold nanoparticles (AuNPs) were synthesized following a bioreductive route using extract of Eriobotrya Japonica leaf. For the synthesis nanoparticles, firstly, leaves collected from Eastern Black Sea region (Akçaabat-TRABZON) in Turkey and dried. Secondly, 20 g dried sample was shaken 400 mL distilled water for 180 min. extracted laboratoary microwave device at 4 minutes, 600 W l...

This of the study was to examine potential presence acrylamide compounds in foods containing amino acid asparagine and reducing sugars that are processed at high temperatures. The initial research carried out determine levels precursors raw material then analyzed amount using HPLC-RP LC-6A Shimadzu with a C18 column sterile aqueous mobile phase. optimization condition instrument achieved temper...

The aim of the present study was to evaluate the properties of linear andnonlinear optics of the Schiff base Salen. Crystal structure of nanoparticles wasdetermined by a Bruker make diffractometer, Cu-K X-rays of wavelength (=1.5406Å). The XRD patterns were recorded in the 2 range of 10–90o with a step width of 0.02s-1. The UV-Vis Spectra recorded on a computerized double - beam Shimadzu 255...

A new simple, accurate and sensitive HPLC pre-column derivatisation method for the low level determination of tert-butylamine in Tigecycline drug substance has been developed. tert-butylamine may be present at a trace level in the Tigecycline drug substance, which is used as a reagent in the manufacturing process of Tigecycline. Chromatographic separations were accompanied under isocratic condi...

The torsion property and rotary fatigue fracture behavior of Smart K file and R reamer made of nickel titanium alloy have been studied by means of Shimadzu Autograph DDS-10T universal tester and man-made cyclic system with curved copper tubes as simulated root canal. The instrument surface and the cyclic fatigue fracture surface have been investigated by optical microscope and scanning electro...

Opuntia ficus-indica belongs to the Cactaceae family and is widespread in semi-arid and arid regions. Cactus pears are known for their health promoting properties which are due to a variety of bioactive molecules. This study aims to identify and quantify phenolic acids, flavonoids and betanin from spineless Opuntia ficus-indica fruits. Fresh mature samples were crushed, and extracted with 50% a...

This article studied the possible effect of rifampicin (RIF), an inhibitor of organic anion transporting polypeptide (Oatp), on the pharmacokinetics of salvianolic acid B (SAB) in rats. Rifampicin was administered intravenously 15 min prior to SAB (5 mg/kg) in rats at doses of 0, 5.0, 10.0 and 20.0 mg/kg, respectively. The concentrations of SAB in plasma and bile were determined using a Shimadz...
