Ethambutol (EMB) is the most frequent "fourth drug" used for the empiric treatment of Mycobacterium tuberculosis and a frequently used drug for infections caused by Mycobacterium avium complex. The pharmacokinetics of EMB in serum were studied with 14 healthy males and females in a randomized, four-period crossover study. Subjects ingested single doses of EMB of 25 mg/kg of body weight under fa...

in this paper, the 1/4 vehicle model have been simulated. the vehicle body acceleration using optimal control has been optimized. the vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. the active suspension can help the vehicle to have a good dynamic behavioral. in this paper, two degrees of freedom dynamic vibration model of a general vehic...

Six new compounds [(CpTi)X, Cp=upsilon(nabla)-c(nabla)H(nabla), X=Ge, Ga, B) have been prepared and their Keggin structures determined by elementary analysis, IR, UV, (infinity)H NMR and (infinity for all)WNMR spectrometry. The results show that the complexes retain Keggin structure. The complexes exhibit antitumoral activity in vitro as shown by MTT experiment.

In this study, we investigate the long-time behavior of global solution anisotropic quasi-geostrophic equation, denoted by $$\theta $$ , where belongs to space $$C_b({\mathbb {R}}^+,H^s({\mathbb {R}}^2))$$ . Our results demonstrate that decays zero as time approaches infinity in $$L^p({\mathbb {R}}^2)$$ norm, with $$p\ge 2$$ Additionally, establish limit $$\Vert \theta (t)\Vert _{H^s}$$ t tends...

Let h = ∑ hαβX Y β be a polynomial with complex coefficients. The Lojasiewicz exponent of the gradient of h at infinity is the upper bound of the set of all real λ such that |gradh(x, y)| ≥ c|(x, y)| in a neighbourhood of infinity in C, for c > 0. We estimate this quantity in terms of the Newton diagram of h. The equality is obtained in the nondegenerate case.

The paper presents a method for H-infinity controller design for a system affected by parametric uncertainty. The proposed method is based on minimising infinity norm of sensitivity function of the nominal system. The design approach is verified by robust stabilization and control of an unstable and perturbed continuous stirred tank reactor (CSTR) with hydrolysis of Propylene Glycol. The contro...
