In this paper the application of Nonlinear Model Predictive Control (NMPC) to a chemical reactor, namely the Open Plate Reactor(OPR), is considered. It is designed a control strategy which allows a safe start-up operation of the reactor and provides an easy handling of system restrictions and nonlinearities originating from the process dynamics. An efficient parameterization of control signals ...

The formation of stars and planetary systems is a complex phenomenon that relies on the interplay multiple physical processes. Nonetheless, it represents crucial stage for our understanding Universe, in particular conditions leading to key molecules (e.g. water) comets planets. Herschel observations demonstrated form gaseous filamentary structures which main constituent molecular hydrogen (H 2 ...

The novel coronavirus was first discovered in Wuhan, China December 2019. This zoonotic disease quickly spread through over 100 countries, including the U.S. World Health Organization (WHO) declared a global health emergency by end of January 2020. Soon after, many states issued mandatory stay-at-home orders, which caused adverse effects for agricultural businesses and food supply chains. Durin...

Let C ⊂ Pr be a general curve of genus g embedded via a general linear series of degree d. The well-known Maximal Rank Conjecture asserts that the restriction maps H(OPr(m)) → H(OC(m)) are of maximal rank; if known, this conjecture would determine the Hilbert function of C. In this paper, we prove an analogous statement for the hyperplane sections of general curves. More specifically, if H ⊂ Pr...

An analytical model for dissolved oxygen concentration in an algal minipond was used to develop a new method for estimating, on-line, the net O(2) production rate (OPR) of the biological process. The method was tested experimentally and was found to provide crucial information on the vitality of the biological process and to provide an early warning of a possible forthcoming collapse of the eco...

BACKGROUND Inequality in life expectancy (ILE) is defined as inequality in the distribution of expected span of life-based on data from survival tables estimated using the Atkinson inequality index. ILE can be influenced by socio-ecological indicators including the Gini coefficient, secondary education, output per worker, and old age pension. This study examined the effects on ILE from a social...

Genetic analysis in 53 early introduced clones of rubber tree (Hevea brasiliensis) collected from different areas in Southern Thailand was performed using RAPD (Random Amplified Polymorphic DNA) and microsatellite markers. Seventeen cultivated clones (34 samples) were also included to compare DNA patterns. DNA was isolated from leaf samples using CTAB buffer. One hundred and ninety two 10-base ...

BACKGROUND Paraoxonase (PON) is a high-density-lipoprotein (HDL) associated enzyme with antioxidative and anti-atherogenic property. Its function is associated with coronary artery disease and its activity genetically controlled. We evaluated whether genetic variation of PON-1 is associated with clinical outcome in a large cohort of Korean patients with drug-eluting stents implantation. METHO...

Reactions of the salicylaldehyde 4-phenylthiosemicarbazone (H(2)L) with selected vanadium(iv) and vanadium(v) precursors ([VO(acac)(2)], [VO(OAc)(2)], VOSO(4), [V(2)O(4)(acac)(2)]) were investigated under aerobic conditions in different alcohols (methanol, ethanol, propanol). In all examined cases mononuclear alkoxo vanadium(v) complexes [VOL(OR)] (1) (OR = OMe, OEt, OPr) were isolated as major...

PURPOSE To detect localized glaucomatous structural changes using proper orthogonal decomposition (POD) framework with false-positive control that minimizes confirmatory follow-ups, and to compare the results to topographic change analysis (TCA). METHODS We included 167 participants (246 eyes) with ≥4 Heidelberg Retina Tomograph (HRT)-II exams from the Diagnostic Innovations in Glaucoma Study...
