The article considers the theory of energy production cycles, developed by N.N. Kolosovskiy, Yu.G. Saushkin, A.T. Khrushchyov, I.V. Komar, I.L. Savel’yeva and other Russian economic geographers. It indicates the history of its development, its relevance and the possibility of successful application for the analysis of the territorial structure and assessment of the prospects for modernization of the economy. At the same time, questions are raised about the inconsistency of this concept with modern market conditions. An attempt is made to rethink the theory of energy production cycles, on the basis of which the concept “production cycle” is formulated and the author’s generalized scheme of coal production cycle with its detailed explanation is given. Approbation of the method is carried out at the Kuznetsk coal complex: the research compares a general scheme of the coal production cycle with the production cycle actually formed around Kuznetsk coals. On the basis of this comparison, the degree of completeness and the reserves for further modernization of this production cycle were revealed. Among the possible directions of coal use, the most promising for introduction in the Kuzbass are indicated, namely: coal semi-coking, gasification (including underground coal) and preparation of water-coal fuel. The research has revealed some positive effects from such modernization of the existing coal production cycle in the Kuzbass.

The paper considers the theory of energy production cycles. It indicates its relevance and the possibility of successful application for the analysis of the territorial structure and assessment of the prospects for modernization of the economy. At the same time, questions are raised about the inconsistency of this concept with modern market conditions. An attempt is made to rethink the theory of energy production cycles, on the basis of which the concept «coal cycle of productions» is formulated and the author’s generalized scheme of this cycle is given. Next, the research compares a general scheme of the coal production cycle with the production cycle actually formed around Kuznetsk coals. On the basis of this comparison, the degree of completeness and the reserves for further modernization of this cycle of production were revealed. Among the possible directions of coal use, the most promising for introduction in the Kuzbass are indicated, namely: coal semi-coking, gasification (including underground coal) and preparation of water-coal fuel. The research has revealed some positive effects from this complication of the existing coal production cycle in the Kuzbass.

SUMMARYBroiler flocks on two Dutch poultry farms were screened weekly for the presence of Campylobacter in fresh caecal droppings during eight consecutive production cycles. Hatchery and fresh litter samples were taken at the start of each new cycle. Water, feed, insects, and faeces of domestic animals, present on the farms were also included in the sampling. Penner seretyping of isolates was used to identify epidemiological factors that contribute to Campylobacter colonization in the broiler flocks. Generally, broiler flocks became colonized with Campylobacter at about 3–4 weeks of age with isolation percentages of 100%, and stayed colonized up to slaughter. A similar pattern of serotypes was found within the various broiler houses on one farm during one production cycle. New flocks generally showed also a new pattern of serotypes. Most serotypes isolated from the laying hens, pigs, sheep and cattle were different from those isolated from the broilers at the same time. Campylobacter serotypes from darkling beetles inside the broiler houses were identical to the ones isolated from the broilers. No Campylobacter was isolated from any of the hatchery, water, feed or fresh litter samples. Conclusive evidence of transmission routes was not found, but results certainly point towards horizontal transmission from the environment. Horizontal transmission from one broiler flock to the next one via a persistent contamination within the broiler house, as well as vertical transmission from breeder flocks via the hatchery to progeny, did not seem to be very likely.

AbstractThe UK pig industry has shown an ability to respond quickly to changing market requirements and improving efficiency of pig meat production. Rapid genetic improvement in breeding stock, particularly in carcass quality and growth traits, together with the adoption of new production strategies, have been the main factors. These changes have had major implications for the way pigs are fed at all stages of the production cycles. Market forces have resulted in a pig population with reduced fat reserves and low appetite. Food intake is a limiting factor at several stages of the production cycle including post weaning, in the case of early-weaned piglets, and the management of young lactating sows. Knowledge of the daily nutrient requirements of the individual animal far exceeds the ability to ensure that those requirements are satisfied by feeding systems in commercial use. Manipulation of food intake to achieve optimum profit is the weakest link in the UK producers' knowledge.

HighlightsUsing an elevated platform with a manure catcher reduced litter moisture content and ammonia concentration.A robotic vehicle encouraged bird movement and use of the elevated platform.Using the elevated platform and robotic vehicle jointly improved broiler paw quality and plumage cleanliness.Abstract. Elevated platform (EP) and robotic vehicle (RV) are two emerging systems aiming to improve environment enrichment and bird activity in broiler housing systems. However, the impacts of these systems on broiler production, welfare, and housing environment have not been evaluated. The objective of this study was to evaluate the effects of using EP and RV individually or jointly on broiler feed conversion ratio (FCR), litter moisture content (LMC), ammonia (NH3) concentration, gait score (GS), paw quality (PQ), plumage cleanliness (PC), and bird activity index (AI). Broilers were reared for eight-week production cycles. Four experimental rooms (54 birds room-1) were randomly assigned four treatments: EP only, RV only, EP and RV (EP+RV), and neither EP nor RV (Ctrl). Broiler GS, PQ, and PC were assessed following welfare protocols. Bird AI was determined through image processing. The experiment was repeated three times. The results showed that overall FCR values were 1.806 for EP, 1.804 for RV, 1.797 for EP+RV, and 1.791 for Ctrl. The normalized LMC values were 23.2% ±4.1% for EP, 32.8% ±4.1% for RV, 23.4% ±2.5% for EP+RV, and 35.7% ±7.0% for Ctrl over the eight-week production cycles. NH3 concentrations were 40% lower in the rooms with EP than in the rooms without EP at the end of the production cycle. Broilers had better PQ in the rooms with EP than in the rooms without EP. Broiler PC seemed better in the rooms with RV compared to those without RV. Operation of RV increased bird AI; however, the benefits in activity encouragement diminished as the broilers grew. The number of broilers on the EP was higher in the EP+RV rooms than in the EP rooms. It is concluded that using EP and RV together may improve broiler welfare and activity without compromising their production performance.

Abstract Following the publication of ‘European Spatial Development Perspective’ in 1999, a large number of theoretical and empirical studies have been carried out on polycentric spatial development especially in European settlements. The relationship between polycentricity and economic competitiveness, environmental sustainability and social cohesion are some of the main concerns of these studies. This study aims to clarify ‘the meaning of polycentricity’ in the case of Turkey, as a developing country and analyse the relationship between polycentric spatial development and economic competitiveness, environmental sustainability and social cohesion. After calculation of morphological polycentricity of the regions at NUTS-5 level, the propositions on the positive effects of polycentric spatial development on economic competitiveness, environmental sustainability and social cohesion is tested by using Pearson correlation and OLS regression models. The results of the empirical study are mixed for these three subjects. Polycentric spatial development has not positive effects on economic competitiveness and social cohesion in Turkey case. Conversely, a positive effect exists in terms of environmental sustainability. It can be said, that to reach those policy aims highlighted by European Spatial Development Perspective, could not be realised by only taken into account polycentric spatial development in Turkey case.

Production system and environmental factors might cause changes in grapevine physiology, affecting grape yield, quality, phenolic composition, and antioxidant potential. The aim of this study was to characterize the quality and antioxidant potential of 'Isabel Precoce' grapes on different training systems and rootstocks in warmer seasons, in tropical conditions. Experimental design was in randomized blocks, in sub-subplots through time and four replicates. Three training systems (overhead trellis, lyre and vertical shoot positioning - VSP) and two rootstocks (‘IAC 572’ and ‘IAC 766’) were studied in the production cycles from July to October, 2017 and from July to October, 2018 in the Submedium of São Francisco Valley. Berry weight; cluster weight; color attributes; berry resistance to compression (COMP); titratable acidity; soluble solids; total soluble sugars (TSS); yellow flavonoids; total anthocyanins; total extractable polyphenols and antioxidant activity by ABTS●+ and DPPH● free radical capture methods were analyzed. Lyre and VSP resulted on increases of 6% and 17% in berry weight and COMP, respectively. Moreover, differences between production cycles were more intense for both variables. In production cycle from July to October 2017, lyre and VSP systems provided increases of 2 g 100 g-1 of TSS and higher anthocyanin and yellow flavonoid contents, while grapes trained in VSP had higher antioxidant activity. Mean values of anthocyanins reached 529.34 mg 100 g-1 in grapes harvested in October 2017. Some grape quality and chemical components showed high variation in warmer seasons of sucessive years, according to training system or rootstock and their combinations

The paper examines the primary drivers and factors influencing the volatility of natural gas prices in the world from January 2007 to July 2020. In addition to the narrow dependence between crude oil and natural gas prices, the influence of renewable energy production and coal production on the price of natural gas has been studied. For that purpose, the method of multiple linear regression was used. The results show that the volatility of natural gas prices significantly depends on the type of the shock in the natural gas market, and that the total production of energy from renewable sources, production of coal and natural gas and the price of crude oil have a significant impact on the price of gas.

Abstract. The act of balancing between an intensive agriculture with a high potential for nitrate pollution and a~drinking water supply almost entirely based on groundwater is a challenge faced by Denmark and similar regions around the globe. Since the 1980s, regulations implemented by Danish farmers have succeeded in optimizing the N (nitrogen) management at farm level. As a result, the upward agricultural N surplus trend has been reversed, and the N surplus has reduced by 30–55 % from 1980 to 2007 depending on region. The reduction in the N surplus served to reduce the losses of N from agriculture, with documented positive effects on nature and the environment in Denmark. In groundwater, the upward trend in nitrate concentration was reversed around 1980, and a larger number of downward nitrate trends were seen in the youngest groundwater compared with the oldest groundwater. However, on average, approximately 48 % of the oxic monitored groundwater has nitrate concentrations above the groundwater and drinking water standards of 50 mg l−1. Furthermore, trend analyses show that 33 % of all the monitored groundwater has upward nitrate trends, while only 18 % of the youngest groundwater has upward nitrate trends according to data sampled from 1988–2009. A regional analysis shows a correlation between a high level of N surplus in agriculture, high concentrations of nitrate in groundwater and the largest number of downward nitrate trends in groundwater in the livestock-dense northern and western parts of Denmark compared with the south-eastern regions with lower livestock densities. These results indicate that the livestock farms dominating in northern and western parts of Denmark have achieved the largest reductions in N surpluses. Groundwater recharge age determinations allow comparison of long-term changes in N surplus in agriculture with changes in oxic groundwater quality. The presented data analysis is based on groundwater recharged from 1952–2003, but sampled from 1988–2009. Repetition of the nitrate trend analyses at five-year intervals using dating of the groundwater recharged in the coming years and a longer time series of the nitrate analyses can reveal the evolution in nitrate leaching from Danish agriculture during the past 10 yr. Similar analyses can be carried out to compare with other regions internationally.

Hopantomide® is a drug containing calcium salt of hopantenic acid. The drug is registered and produced in Russia (Usolye-Siberian Chemical Pharmaceutical Factory) with the use of own raw materials and goes through a full production cycle, which guarantees quality control at every stage. Hopantomide belongs to nootropics and has neurometabolic, neuroprotective, and neurotrophic properties, as well as anticonvulsant action. According to the package insert and results of the studies evaluating the efficacy of hopantenic acid, Hopantomide has a number of positive therapeutic effects. It increases brain resistance to hypoxia and toxic substances, stimulates anabolic processes in neurons, improves mental and physical performance, combines moderate sedative action with mild stimulating effect, reduces motor excitability with simultaneous regulation of behavior, improves the metabolism of gamma-aminobutyric acid and normalizes its level in individuals with chronic alcohol intoxication and after alcohol withdrawal, has anxiolytic and thymoleptic properties, inhibits the abnormal bladder reflex and detrusor tone. This ensures high efficacy of Hopantomide in the treatment of various nervous diseases in different age groups. In our opinion, the combination of various positive effects of just one drug can significantly reduce the pharmacological burden. In this review, we discuss well-known and potential mechanisms of action, indications for its use with a focus on Hopantomide benefits in pediatric neurological practice, and studies evaluating the efficacy of hopantenic acid in clinical practice. Particular attention is paid to the possibilities of its use in children, including those with attention deficit hyperactivity disorder and developmental delay, as well as the part of combination therapy for epilepsy together with antiepileptic drugs.Drugs containing hopantenic acid are well tolerated by patients, including children who receive it for a long time.
