determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولthe effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولVanadium in Cold-rolled Sheet Steels
In hot rolled products, which are the subject of other presentations here, vanadium has been used for many years in high strength products, often in combination with other microalloying additions such as niobium or titanium. Vanadium can provide important contributions via both precipitation strengthening and ferrite grain refinement (due to austenite conditioning during thermomechanical proces...
متن کاملSpectrophotometric determination of vanadium(V) in minerals, steels, soil and biological samples using phenothiazine derivatives.
Two simple, rapid and sensitive spectrophotometric methods have been proposed for the determination of vanadium(V) using butaperazine dimaleate (BPD) and propionyl promazine phosphate (PPP). These methods are based on the formation of red-colored radical cations on reaction with vanadium(V) in phosphoric acid medium, with their absorbance maxima at 513 nm. Beer's law is valid over the concentra...
متن کاملDetermination of traces of phosphorus in steels by laser ablation/ low-pressure helium-ICP-MS.
coupled plasma–mass spectrometry (ICP-MS) offers a powerful and rapid analytical method for different solid samples (e.g., rocks,1–3 metals,2,3 and ceramics3), the mass spectral interference often becomes a serious problem.4 For example, the determination of phosphorus (31P, monoisotopic element) is disturbed by 14N16OH+ and an adjacent large background peak of O2, which mainly originates from ...
