Взаимосвязь промышленного и финансового стресса в российской экономике в условиях смены монетарного режима

The relevance of the paper is defined by significant impact of financial shocks on various sectors of the Russian economy, which undermines the stability of the country’s economic system. Therefore, it is essential to study the sources of financial shocks, the mechanisms of their distribution and ways to manage them. The purpose of the paper is to specify the impact of financial stress on industrial stress in the Russian economy and to determine the role of monetary policy in their interaction. The novelty of the research consists in the development of a methodology for constructing financial and industrial stress indices, the establishment of the mechanism of their interaction under different monetary regimes of the central bank. The construction of stress indices is carried out on the basis of the selected indicators of the financial market and industrial sector of the economy, the use of the principal component analysis for their aggregation, and mathematical transformation of the first principal component. The direction of interaction between financial and industrial stress in the Russian economy is determined using the Granger causality test. The construction of autoregressive distributed lag models (ARDL models) allows estimating the impact of financial stress, as well as monetary policy parameters (the scale of lending by the central bank to commercial banks and the deviation of the central bank’s key rate from the market rate borrowing) on industrial stress in the Russian economy. The research results in estimates of the strength of the relationship between financial and industrial stress in the Russian economy in two periods: before the change in the monetary regime (2006 — end of 2014) and after the change in the monetary regime (end of 2014–2019). It is concluded that in the first period the impact of financial stress on industrial stress was faster and stronger. In the second period, the weakening and distancing of this influence in time is explained by the change of the monetary regime of the Bank of Russia, which indicates an increase in the effectiveness of the monetary policy instruments of the Bank of Russia to counter “financial contagion” of the industrial sector.Актуальность исследования обусловлена существенным влиянием финансовых шоков на различные сектора российской экономики, что приводит к нарушению устойчивости экономической системы страны. Поэтому крайне важно знать источники финансовых шоков, механизмы их распространения и способы управления ими. Цель исследования — раскрытие особенностей влияния финансового стресса на промышленный стресс в российской экономике и определение роли денежно-кредитной политики в их взаимодействии. Новизна исследования заключается в развитии методологии построения индексов финансового и промышленного стресса, установлении механизма их взаимодействия в условиях разных монетарных режимов центрального банка. Построение индексов стресса осуществляется на основе отбора индикаторов финансового рынка и промышленного сектора экономики, использовании метода главных компонент для их агрегирования и математического преобразования первой главной компоненты. С помощью теста Грейнджера на причинность определяется направленность взаимодействия финансового и промышленного стресса в российской экономике. На основе построения моделей авторегрессии с распределенным лагом (ARDL моделей) выявляется характер и степень воздействия финансового стресса, а также параметров денежно-кредитной политики (масштабов кредитования центральным банком коммерческих банков и отклонения ключевой ставки центрального банка от рыночной ставки заимствования) на промышленный стресс в российской экономике. Результатом исследования являются оценки силы связи между финансовым и промышленным стрессом в российской экономике для двух периодов: до изменения монетарного режима (2006 — конец 2014 г.) и после изменения монетарного режима (конец 2014–2019 г). Сделан вывод, что в первом периоде влияние финансового стресса на промышленный стресс было более быстрым и сильным. Во втором периоде ослабление и отдаление этого влияния во времени объясняется сменой монетарного режима Банка России, что свидетельствует о повышении эффективности инструментов денежно-кредитной политики Банка России в противодействии «финансовому заражению» промышленного сектора экономики

РАЗРАБОТКА ТЕХНОЛОГИИ И НОРМАТИВНОЙ ДОКУМЕНТАЦИИ НА ИМПОРТОЗАМЕЩАЮЩИЙ ПРОДУКТ ПЕРЕРАБОТКИ БРОККОЛИ

The aim of the present investigation was development of an efficient technology for obtaining powders from fresh broccoli; determination of the possibility of using domestic production of broccoli as an import-substituting product; development of regulatory documentation for broccoli powders for the food industry. The research was carried out jointly with the representatives of the Federal Scientific cen-ter of vegetable production on an experimental basis in 2016. The domestic Tonus variety of broccoli (Federal Scientific center of vegetable production) and the Maraton F1 hybrid (France), differing in appearance, vegetative period, biochemical and physical characteristics were chosen. Technology of broccoli powder production from domestic and imported products was developed using two methods of drying convection and lyophilization. The gentle drying conditions of broccoli freeze drying compared to convective drying technology provided higher content of both vitamin C and polyphenols in the final powder. Comparative studies of organoleptic and physico-chemical properties of powders obtained from domestic and imported broccoli demonstrated close quality parameters, indicating the possibility of effective domestic broccoli utilization and import substitution. For the first time in the Russian Federation, the "Organization Standard" was developed for regulation of the quality parameters of broccoli powders intended for use in the food industry.Цель данных исследований заключалась в разработке эффективной технологии получения порошков из свежей капусты брокколи; установлении возможности использования брокколи отечественного производства как импортозаме-щающего продукта; разработке нормативной документации на порошки брокколи для использования в пищевой промыш-ленности. Исследования проводили совместно с представителями ФГБНУ ВНИИССОК на экспериментальной базе в посевной период 2016 года. К исследованиям принята капуста брокколи: отечественный сорт Тонус (селекции ФГБНУ ВНИИССОК) и гибрид Маратон F1 (производитель Франция), различающиеся по внешним признакам, продолжительности вегетации, биохимическим и физическим характеристикам. Технология порошков брокколи из сырья отечественного и импортного производств осуществлена с применением двух способов сушки – конвективной и лиофильной. Щадящие условия высушивания свежего продукта при лиофильной сушке обеспечивали повышенное содержание в конечном порошке как витамина С, так и полифенолов по сравнению с порошками конвективной сушки. Сравнительными исследованиями органолептических и физико-химических свойств порошков, полученных из сырья разного происхождения, установлены близкие показатели качества, что является обоснованием для использования отечественного сырья в качестве импортозамещающего. Впервые в Российской Федерации разработан «Стандарт организации», призванный регламентировать показатели качества порошков брокколи, предназначенных для использования в пищевой промышленности

Meta-Analysis of Genome-Wide Scans for Human Adult Stature Identifies Novel Loci and Associations with Measures of Skeletal Frame Size

Recent genome-wide (GW) scans have identified several independent loci affecting human stature, but their contribution through the different skeletal components of height is still poorly understood. We carried out a genome-wide scan in 12,611 participants, followed by replication in an additional 7,187 individuals, and identified 17 genomic regions with GW-significant association with height. Of these, two are entirely novel (rs11809207 in CATSPER4, combined P-value = 6.1×10−8 and rs910316 in TMED10, P-value = 1.4×10−7) and two had previously been described with weak statistical support (rs10472828 in NPR3, P-value = 3×10−7 and rs849141 in JAZF1, P-value = 3.2×10−11). One locus (rs1182188 at GNA12) identifies the first height eQTL. We also assessed the contribution of height loci to the upper- (trunk) and lower-body (hip axis and femur) skeletal components of height. We find evidence for several loci associated with trunk length (including rs6570507 in GPR126, P-value = 4×10−5 and rs6817306 in LCORL, P-value = 4×10−4), hip axis length (including rs6830062 at LCORL, P-value = 4.8×10−4 and rs4911494 at UQCC, P-value = 1.9×10−4), and femur length (including rs710841 at PRKG2, P-value = 2.4×10−5 and rs10946808 at HIST1H1D, P-value = 6.4×10−6). Finally, we used conditional analyses to explore a possible differential contribution of the height loci to these different skeletal size measurements. In addition to validating four novel loci controlling adult stature, our study represents the first effort to assess the contribution of genetic loci to three skeletal components of height. Further statistical tests in larger numbers of individuals will be required to verify if the height loci affect height preferentially through these subcomponents of height

Structure of the Nucleotide Radical Formed during Reaction of CDP/TTP with the E441Q-α2β2 of E. coli Ribonucleotide Reductase

The Escherichia coli ribonucleotide reductase (RNR) catalyzes the conversion of nucleoside diphosphates to deoxynucleotides and requires a diferric-tyrosyl radical cofactor for catalysis. RNR is composed of a 1:1 complex of two homodimeric subunits: α and β. Incubation of the E441Q-α mutant RNR with substrate CDP and allosteric effector TTP results in loss of the tyrosyl radical and formation of two new radicals on the 200 ms to min time scale. The first radical was previously established by stopped flow UV/vis spectroscopy and pulsed high field EPR spectroscopy to be a disulfide radical anion. The second radical was proposed to be a 4′-radical of a 3′-keto-2′-deoxycytidine 5′-diphosphate. To identify the structure of the nucleotide radical [1′-[superscript 2]H], [2′-[superscript 2]H], [4′-[superscript 2]H], [5′-[superscript 2]H], [U−[superscript 13]C, [superscript 15]N], [U−[superscript 15]N], and [5,6 -[superscript 2]H] CDP and [β-[superscript 2]H] cysteine-α were synthesized and incubated with E441Q-α2β2 and TTP. The nucleotide radical was examined by 9 GHz and 140 GHz pulsed EPR spectroscopy and 35 GHz ENDOR spectroscopy. Substitution of [superscript 2]H at C4′ and C1′ altered the observed hyperfine interactions of the nucleotide radical and established that the observed structure was not that predicted. DFT calculations (B3LYP/IGLO-III/B3LYP/TZVP) were carried out in an effort to recapitulate the spectroscopic observations and lead to a new structure consistent with all of the experimental data. The results indicate, unexpectedly, that the radical is a semidione nucleotide radical of cytidine 5′-diphosphate. The relationship of this radical to the disulfide radical anion is discussed.National Institutes of Health (U.S.) (GM29595)(EB002804)(EB002026

Residues of chlorinated pesticides in mother\u27s milk and child\u27s serum

Uzorci mlijeka i seruma 27 hospitaliziranih dojilja iz Bjelovara i Zaboka s okolnim mjestima analizirani su na ostatke kloriranih insekticida aldrina, dieldrina, endrina, heptaklora, heptaklor epoksida, lindana i ostalih stereoizomera heksaklorcikloheksana, pp-\u27DDT-a i metabolita (pp-\u27DDE i pp-\u27DDD) i op-\u27DDT. Posebno je još analizirano 18 seruma majki i isto toliko seruma njihove djece koji su svi iz Zagreba. U uzorcima smo dokazali prisutnost samo Gama-HCH (Lindan). Alfa-HCH, pp-\u27DDE, op-\u27DDT, pp-\u27DDD i pp-\u27DDT. Koncentracije nađenih insekticida mnogo su veće u mlijeku dojilja nego u serumima. U serumima djece bilo je manje samo pp-\u27DDE i pp-\u27DDT nego u serumima njihovih majki. Uzorci seruma dojilja iz Zaboka i okolnih mjesta, hospitaliziranih u Zaboku i serumi dojilja iz Bjelovara hospitaliziranih u Zagrebu (N = 27) sadržavaju više navedenih insekticida nego uzorci seruma dojilja s područja Zagreba (N = 18).Milk samples obtained from 27 hospitalized lactating women and an equal number of sera from the same women were examined for residues of chlorinated hydrocarbon insecticides: aldrin, dieldrin, endrin, heptachlor, heptachlorepoxide, lindan and other steroisomers of hexachlorcyclohexane, pp\u27DDT and its metabolites (pp\u27-DDE, pp\u27-DDD) and op\u27-DDT. Additional 18 samples of mother\u27s sera and an equal number of their children\u27s sera were examined separately. The aim was to find out whether there is a correlation between the pesticide residues in mother\u27s serum and mother\u27s milk and in the serum of the mother and her child. The insecticides were determined according to the procedure used by the US Food and Drug Administration (4). Chlorinated hydrocarbon insecticides in the serum were examined with the method described by Wyllie and coworkers (5). In all samples only the presence of a-HCH, y-HCH, pp\u27-DDE, op\u27-DDT, pp\u27-DDD and pp\u27-DDT could be demonstrated. The concentration ratio between mother\u27s milk and serum was between 4 and 11. The concentration ratio between mother\u27s and child\u27s serum was below 1 except for pp\u27-DDE and pp\u27-DDT

Environmental Chamber Studies of Atmospheric Reactivities of Volatile Organic Compounds: Effects of Varying Chamber and Light Source

Photochemical oxidant models are essential tools for assessing effects of emissions changes on ground-level ozone formation. Such models are needed for predicting the ozone impacts of increased alternative fuel use. The gas-phase photochemical mechanism is an important component of these models because ozone is not emitted directly, but is formed from the gas-phase photochemical reactions of the emitted volatile organic compounds (VOCs) and oxides of nitrogen (NO{sub x}) in air. The chemistry of ground level ozone formation is complex; hundreds of types of VOCs being emitted into the atmosphere, and most of their atmospheric reactions are not completely understood. Because of this, no chemical model can be relied upon to give even approximately accurate predictions unless it has been evaluated by comparing its predictions with experimental data. Therefore an experimental and modeling study was conducted to assess how chemical mechanism evaluations using environmental chamber data are affected by the light source and other chamber characteristics. Xenon arc lights appear to give the best artificial representation of sunlight currently available, and experiments were conducted in a new Teflon chamber constructed using such a light source. Experiments were also conducted in an outdoor Teflon Chamber using new procedures to improve the light characterization, and in Teflon chambers using blacklights. These results, and results of previous runs other chambers, were compared with model predictions using an updated detailed chemical mechanism. The magnitude of the chamber radical source assumed when modeling the previous runs were found to be too high; this has implications in previous mechanism evaluations. Temperature dependencies of chamber effects can explain temperature dependencies in chamber experiments when Ta-300{degree}K, but not at temperatures below that
