Necessary p-th order optimality conditions for irregular Lagrange problem in calculus of variations

The paper is devoted to singular calculus of variations problems with constraints which are not regular mappings at the solution point, e.i. its derivatives are not surjective. We pursue an approach based on the constructions of the p-regularity theory. For p-regular calculus of variations problem we present necessary conditions for optimality in singular case and illustrate our results by classical example of calculus of variations problem

Flowers of marigold (Tagetes) species as a source of xanthophylls

yesBSUThe accumulation of xanthophylls in flowers of marigold (Tagetes) species cultivated under conditions of the Belgorod region has been studied. Five cultivars representing three marigold species were investigate

Legionellosis Agent Indication Using Immunochromatography with Visual and Digital Video Detection

Proposed was the immunochromatographic express-test for legionellosis agent detection in water environment. The method is high-sensitive and specific allowing to detect only first serogroup of legionellosis agent. That is of high importance for identification of isolated cultures of legionella and monitoring of Legionella pneumophila presence in environment objects

Gain Stabilization of SiPMs and Afterpulsing

The gain of silicon photomultipliers increases with bias voltage and decreases with temperature. To operate SiPMs at stable gain, the bias voltage can be readjusted to compensate for temperature changes. We have tested this concept with 30 SiPMs from three manufacturers in a climate chamber at CERN varying the temperature from 1 degree C to 48 degrees C. We built an adaptive power supply that is based on a linear dependence of bias voltage versus temperature. With one selected dVb=dT value, we stabilized four SiPMs simultaneously. We fullled our goal of stabilizing most SiPMs with gain changes of less than 0.5% in the 20-30 degrees C temperature range. We studied afterpulsing of SiPMs for dierent temperatures and bias voltages

Studies of Physalis alkekengi L. fruits as a source of xanthophylls

yesBSUThe studies reported here established that fruits of the perennial and quite hardy plant Physalis alkekengi grown in the conditions of the Belgorod area accumulate zeaxanthin (and B-cryptoxanthin) derivatives at levels of up to 20 mg/g of husks, which are needed for the prevention of age-related visual los
