Influence of light wavelength on viability and reproductive function of hens

The article presents the results of influence of monochrome light with different light wavelengths on the hens’ viability and productivity. For this purpose, in the conditions of a modern complex for production of food eggs in a poultry house with an area of 2915 m2, 4 groups of hens of the industrial herd “Hy-Line W-36” were formed, each of which was kept in a separate poultry house similar in area and cage equipment. Each poultry house was equipped with “Big Dutchman” cage batteries, consisting of 1176 cages with an area of 40544 cm2. The differences between the poultry houses applied only to LED lamps. Hens of the 1st group were kept using LED lamps with a peak light wavelength of 458 nm (blue color of the spectrum), the 2nd group – 603 nm (yellow color of the spectrum), the 3rd group – 632 nm (orange color of the spectrum) and 4 groups – 653 nm (red color of the spectrum). Every day, for 34 weeks of the productive period (up to 52 weeks of age), the number of eggs laid by the laying hens of each group was determined. The number of hatched hens (due to death and culling) was also counted daily and the number of livestock was determined. Once a week, the weight of eggs and live weight of laying hens were measured from certain labeled cages. It was found that the reduction of the wavelength of light during the keeping of hens in the cages of multi-tiered batteries affects their viability and reproductive function. The decrease in the peak wavelength from 653 to 632 nm, which was manifested by a change in the color of light from red to orange, was accompanied by a decrease in the preservation by 0.3 %, body weight – by 0.8 %, egg laying on the initial laying – by 3.1 %, egg-laying per average laying hen – by 2.8 % and feed costs – by 0.2 %. The decrease in the peak wavelength to 603 nm, that is the change in the color of light from red and orange to yellow, was accompanied by a decrease in the preservation by 6.4–6.7 %, body weight – by 0.5–1.3 %, egg production by initial laying hen – by 7.1–10.0 %, laying hens on the average laying hen – by 0.4–3.2 % and feed costs – by 2.0–2.1 %. The decrease in the peak wavelength to 458 nm, that is the change in light color from red, orange and yellow to blue, was accompanied by a decrease in the preservation by 3.2–9.9 %, body weight – by 5.2–6.5 %, laying hens per initial laying hen – by 6.4–15.8 %, laying hens per middle laying hen – by 2.9–6.0 % and feed costs – by 1.0–3.1 %.

Development of ATP13A2-deficient In vitro Model for PARK9 Parkinson’s Disease

Background: PARK9 familial Parkinson’s disease (PD) is caused by a loss-of-function mutation in the ATP13A2 gene in which the mutation impairs the autophagic-lysosomal degradation pathway and induces intraneuronal accumulation of alpha-synuclein. RNA interference has been a useful tool in generating in vitro knockdown model to study the physiological role of the gene. However, the availability of a validated ATP13A2-deficient in vitro model is limited. Objective: This study aimed to develop the ATP13A2-deficient PD model by delivering ATP13A2 siRNA into neuroblastoma cells using carbonate apatite nanoparticles (CA NPs). Methods: CA NPs were fabricated using different concentrations of calcium chloride and characterised in the presence or absence of ATP13A2 siRNA. Time-dependent stabilities of CA NPs and CA NPs-associated siRNA (CA-siRNA) complex were evaluated by pH, turbidity, size, and zeta potential measurements. The dissolution abilities at acidic conditions of both complexes were investigated. Following that, green fluorescence protein (GFP) and four different siRNAs targeting ATP13A2 (siRNA_5, 6, 7, and 8) were transfected to cells with the fabricated CA NPs. Western blot was performed to determine the knockdown effect of the four siRNAs. Results: It was found that 4 mM calcium chloride was ideal for CA NP formation, while an incubation time of 48 hours was required to maintain the stability of nanoparticles. Successful transfection was confirmed by detection of fluorescence signal from the GFP plasmid and the subsequent silencing of this signal by transfecting GFP siRNA. Western blot analysis revealed that ATP13A2 protein expression was significantly reduced to 20% upon transfection with 20 nM of siRNA_5. Conclusion: ATP13A2-deficient PD model was successfully developed.

MODEL OF OPERATION OF COMBAT AIRCRAFT GROUND TRANSPORTATION SERVICE SYSTEMS

The article analyzes the current state and prospects of development of systems of ground transport maintenance of aircraft, which allowed to form the purpose of the study in this development. The chosen topic is quite relevant, because effective organization of combat aircraft maintenance allows raising combat effectiveness of Ukrainian air forces. One of the directions of maintenance cost reduction is effective use of resources. The study establishes that in order to improve the quality of transport maintenance and increase the combat effectiveness of the Armed Forces and National Guard of Ukraine, it is necessary to pay attention to the use of new transport vehicles, especially modular designs and development of technology to determine the optimal distribution of transport resources for aircraft maintenance, for different conditions of the transport complex and different types of aircraft maintenance. The authors propose to consider two aircraft maintenance schemes – existing using existing technology and proposed using a modular design. In a modular design, a wheeled tractor acts as a tug, which drives mobile modules, which are special means for servicing aircraft. Such an energy-efficient vehicle may consist of 4 modules at a time. The process of delivering the cargo required for servicing the aircraft at the airport is estimated at costs, which form a set of cost values for each technological process of servicing the aircraft. The set criterion is influenced by the parameters: the cost of performing a unit of the corresponding operation, the cost of one hour of work of one worker, the time of performing the corresponding operation, the number of modules involved to perform the corresponding service, the number of aircraft. The developed models of functioning of combat aircraft maintenance systems for maintenance will allow to take into account the influence of random factors, to assess the possibility of using modular designs, as well as to determine the efficiency of existing resources on airfields in Ukraine.

Complexity factor for anisotropic self-gravitating sphere in Rastall gravity

This paper investigates the new definition of complexity factor for the case of irrotational spherical relativistic structure in the Rastall theory of gravity (RTG). To do so, we assumed static spherically symmetric metric with anisotropic self-gravitating fluid. We studied Rastall field equations, generalized nonconservation equation, mass function and physical impacts of Rastall parameter [Formula: see text] on various material variables by employing certain observational data of compact objects like PSR J1614-2230, 4U1608-52, SAX J 1808.4-3658, 4U1820-30 and Vela X-1. We obtained structure scalars through orthogonal decomposition of the curvature tensor and then utilize these scalars to find the complexity factor of the self-gravitating spherical structure. We examined that the vanishing complexity factor condition is an effective energy density inhomogeneity and an effective anisotropy of pressure which must cancel each other, employed the condition [Formula: see text]. Moreover, we also depicted the solutions of interior formation of spherical stellar object regarding to this vanishing complexity condition. Finally, it is found that the complexity of the system enhances due to the presence of nonminimal to curvature matter couple parameter [Formula: see text]. It is very fascinating to report here that these outcomes could be recovered back to former solutions about complexity factor in General Relativity (GR) by imposing [Formula: see text].

Anisotropic star models in the context of vanishing complexity

We use the definition of complexity for static and self– gravitating objects to build up three physical general relativistic anisotropic models fulfilling the vanishing complexity condition which serves to provide the extra information needed to close the system of Einstein field equations. We evaluate the physical acceptability of these models by testing some of the conditions that the geometric and material sector must satisfy in order to be considered as reasonable realistic models. We present the results of this analysis by asserting that the studied cases demonstrate to be feasible and stable under the chosen set of parameters. Furthermore, the P⊥=0 and the Consenza’s anisotropy models that seem not satisfying the expect conditions are also discussed.

A study on the design strategies of Fish Landing Jetty Complexes in Malaysia to enhance the efficiency of the building

Malaysia has a booming and successful fishery development. Fisheries Development Authority of Malaysia Complexes (LKIM) are located in every state of Malaysia to function as a fish landing jetty complex to allow fishing vessels for fish handling operations. However, the design and facility of Fish Landing Jetty Complexes in Malaysia are not up to date even though the fishery development contribute to Malaysia’s economy. Proper facilities and design strategies of fish landing jetty will ensure that fish handling operations work efficiently and enhance the fishery development in Malaysia. In this research, the design components and facilities of fish landing jetty complexes are studied for determining the design strategies of fish landing jetty complexes in Malaysia to enhance the efficiency of the building itself. In this research, a few precedent study and survey questionnaire had been conducted as a research methodology to review and compare the design components and facility of the precedent studies. Besides, the survey questionnaire is to collect the data and their opinion from the general public and users of the Fish Landing Jetty Complex to understand their satisfaction and expectation towards the current condition of the Fish Landing Jetty Complex in Malaysia. There are 41% of respondents are stated that majority of the Fish Landing Jetty Complexes in Malaysia are unsuccessful in achieving the efficiency of the fish landing process. The design strategies of Fish Landing Jetty Complex should consider on the working flow diagram of fish landing. Application of mechanical quay-side lifting winches, built-in conveyor system, rainwater harvesting system and solar energy able to increase the efficiency of the building. It is important to apply the commercial and public recreation spaces inside a Fish Landing Jetty Complex to sustain longer and produce revenue to the building.

Nonspecific adaptive reactions of hen’s body under the influence of light wavelength

The sources of artificial light of the latest generation in poultry farming are LED lamps, which are able to give monochrome light. It is known that the wavelength of light affects the behavior, well-being and productivity of birds, but the effect of changing the wavelength of light under monochrome light has not yet been studied. Nonspecific adaptive reactions of hens under the influence of light wavelength of monochrome light have been studied. For this purpose, in the conditions of a modern complex for food eggs production, 4 groups of hens of industrial herd «Hy-Line W-36» were formed, each of which was kept in a separate poultry house-analogue in terms of area and cage equipment. Hens of the 1st group were kept using LED lamps with a peak light wavelength of 460 nm, the 2nd group — 600 nm, the 3rd group — 630 nm and the 4th group — 650 nm. To assess the adaptive and overall reactive immunological potential of hens, integrated immunohematological indices of intoxication, inflammatory activity and nonspecific reactivity were determined on the ba­sis of an extended general blood test. It was found that a decrease in the wavelength of light increases the indices of leukocyte shift, the heterophiles to leukocytes ratio, immunoreactivity, the heterophiles to monocytes ratio, the lymphocytes to monocytes ratio and the lymphocytes to eosinophils ratio. This indicates a shift of the leukocyte formula to the left, the predominance of nonspecific protective cells due to a functional increase in bone marrow proliferative activity and is expressed in increased heterophiles, increased activity in the microphage-macrophage immune response system and indicates the presence of high levels in the body and impaired immunological reactivity, and can inform about the autoimmune nature of the pathological process. It is shown that at the same time there is a decrease in lymphocytegranulocyte index, leukocyte-ESR ratio, total and lymphocyte indices, which confirms the shift of the leukocyte formula to the left and indicates a predominance of activation of the cellular link due to intoxication. Simultaneous increase in the leukocyte shift index and decrease in the lymphocyte-granulocyte index indicates the development of endogenous intoxication in hens and impaired immunological reactivity due to autointoxication of the body during the destruction of its own cells.

How do occupational relatedness and complexity condition employment dynamics in periods of growth and recession?

ABSTRACT Related diversification has generated interest in policy (Smart Specialisation) and academic (regional branching) circles, linking path creation to regional capabilities and performance. We develop measures of occupational relatedness and complexity for local labour market areas in Sweden over the period 2002–12 to examine whether these constructs are helpful in explaining spatial and temporal variations in employment growth. The results indicate that increases in occupational relatedness are positively related to employment growth, while changes in occupational complexity have no significant impact. Separating the results either side of the global financial crisis shows that the influence of relatedness on employment is stronger pre-2008, while after the crisis building specialization in more complex occupations was positively associated with employment growth.

Policy Diffusion Speed: A Replication Study Using the State Policy Innovation and Diffusion Database

Data accumulation efforts are pushing the study of policy innovation diffusion in new directions. This replication study uses one such effort, the State Policy Innovation and Diffusion database, to interrogate the claim that policy attributes like salience and complexity condition the speed of innovation adoption. The study finds that policy complexity does push the effect of policy salience in a negative direction. However, it also finds substantial heterogeneity in these conditional effects across State Policy Innovation and Diffusion’s major constituent datasets. In addition, while not completely answering questions about convenience sampling bias, the study shows that the fundamental results do not change with one re-weighting of the results to capture a hypothetical distribution of the population of state policy innovations. The article concludes with future directions for the study of both policy diffusion within American federalism and cross-national diffusion.

Research on the Prewarning Model of Relationship Risk Levels in Industry Collaborative Innovation Alliances across Provinces in China

The governments need beforehand to perceive the innovative relationship risk because they are one of the innovation subjects in those industry collaborative innovation alliances. However, it is difficult for innovation subjects to quantify the risks for industry collaborative innovation alliances due to the complexity, nonlinear, and dynamic condition. This paper firstly constructs an ordered logistic model, uses the following as independent variables: the collaborative degree, the ratio of science technology expenditure to GDP, the ratio of education expenditure to GDP, the ratio of finances to GDP, and uses the levels of risk as the dependent variable. Then, this paper uses the panel data of 30 provinces in China (Hainan is not included) from 2010 to 2018 to fit the model. Based on the fitting results, the research has gained the relationship risk prewarning model in industry collaborative innovation alliances by using the collaborative degree as an independent variable. The governments at all levels can use this relationship risk prewarning model to percept risk levels and reckon the corresponding probability which exists in industry collaborative innovation alliances. Furthermore, there are regional influences existing in the prewarning relationship risk levels in industry collaborative alliances. The east and middle areas have significant regional influence, but it does not exist among west areas and others. The governments at all levels may consider the regional differences.

Hen reproductive function under the influence of technological stressor

Modern industrial poultry enterprises use cage equipment for keeping laying hens, which is located in 12 and even 15 tiers, forming 4–5 floors. This makes it possible to increase the birds concentration in the poultry house by 4–5 times as compared to 3-tier cage batteries, and by 8–10 times as compared to the outdoor method of keeping. When using a 4–5 floors arrangement of cage batteries, the number of hens in one poultry house can reach 590 thousand birds. However, there are no data on the effect of such keeping on the physiological state of hens. Therefore, it is relevant to study the effect of the height of the cage battery on the reproductive function of laying hens of an industrial herd, which forms the efficiency of production of edible eggs. For this, in the conditions of a modern complex for the production of edible eggs, 4 groups of hens were formed, each of which was kept on a separate floor-analogue in area and cage equipment, located in one poultry house. Each floor was equipped with 3-tier cage batteries: tiers 1–3 were part of the 1st floor, tiers 4–6 — on the 2nd, 7–9 tiers — on the 3rd, and tiers 10–12 — 4th floors of cage equipment. The reproductive function of hens was assessed by the egg production for the initial and middle hens, its intensity and the weight of eggs. The research results showed that the content of layers in the cages of the batteries of the second floor was accompanied by a slight decrease in the safety of livestock — by 0.2–0.5%, egg production per initial layer — by 1.9–2.2%, which led to a decrease in the gross production of eggs by 0.6–0.7 million eggs, egg mass — by 48.9–67.0 tons and a decrease in the European efficiency factor by 0.7–0.9 units.Whereas when keeping laying hens in the cages of batteries on the first floor, there was a decrease in preservation by 10.3–10.8%, egg production per initial hen — by 6.4– 8.4% and body weight — by 7.5–8.1%, which led to a decrease in the gross production of eggs by 1.9–2.6 million pieces, egg mass — by 143.8–210.8 tons and a decrease in the level of the European coefficient of efficiency of egg production by 1.7–2.6 units. Thus, an increase in the layering of the cage equipment does not have a negative effect on hens reproductive function and the keeping of laying hens in the cages of the batteries of the first floor leads to the development of a stress state in them, which manifests itself in a decrease in the safety and deterioration of hens reproductive function, which leads to decrease in the efficiency of egg production.

Оценка биоиндикаторов физиолого-биохимических показателей ремонтно-маточного стада осетровых рыб

More recently, sturgeon fish were classified as a national treasure of our country, since among the world's reserves, Russia accounted for up to 90%. Nevertheless, over the past 10-15 years there has been a catastrophic decline in sturgeon stocks in almost all water bodies of the country. The main reason for the widespread landslide decline in stocks of sturgeon fish is the excess of the withdrawal over the recruitment of generations. In conditions of anthropogenic pollution of water bodies, the creation of sturgeon broodstock using industrial methods of rearing is a way to preserve the gene pool of these most valuable representatives of the world ichthyofauna and obtain seedlings for commercial fish farming. In connection with the use of industrial methods of fish rearing, the need for their physiological control increases. One of the sensitive methods that allows you to quickly and accurately establish the physiological state of fish, as well as assess the conditions for their cultivation, is the physiological-biochemical, hematological method, the leukocyte formula, since blood is a polyfunctional system of the body that dynamically responds to all changes, both internal and external. Wednesday. The aim of the study is to determine the boundaries of the reference values in terms of physiological, biochemical, hematological indicators, as well as the leukocyte formula in aquatic organisms of different-age replacement broodstock of sterlet and the quality of conditions for its cultivation in the conditions of the cage complex.

Heat synchronization and the effectiveness of insemination of cows of Holstein breed under the conditions of the dairy complex

The food security of country is largely determined by the development of animal husbandry branches. Dairy cattle breeding is of particular importance, which has been actively developing in recent years due to the modernization of farms and complexes, the introduction of innovative technologies and the formation of a highly productive breeding herd. The most important link in the development of dairy cattle breeding is the reproduction of the herd. Modern technologies make it possible to use hormonal drugs in order to optimize the reproductive traits of animals. The results of clinical and experimental studies have shown the important role of hormones in the regulation of physiological functions, as well as the possibility of their use for directed changes in metabolism, productivity and fertility of animals. The purpose of the research was to assess the influence of methods of synchronization of heat of cows on the pregnancy rate under the conditions of the dairy complex. The research data on the effectiveness of insemination when identifying animals in visually heat and using Heatime neck strips, as well as when using heat synchronization programs such as Presynch and Double Ovsynch have been presented in the article. The research has been carried out under the conditions of a modern dairy complex on a highly productive herd of cows of Holstein breed. Differences in the effectiveness of insemination by using the studied methods were revealed from 49,1 to 72,5 %. The highest conception rate has been observed in first-calf heifers (83,0 %) and cows (62,5 %) inseminated using the Double Ovsynch protocol. The dependence of the level of conception rate on the presence of diseases suffered by cows during the newcalving period and until the moment of insemination has been noted. In sick animals, the conception rate for groups of first-calf heifers and cows was significantly lower than in healthy animals. Thus, according to the Double Ovsynch insemination protocol, the conception rate in healthy animals was 83,7 %, and in those who were ill – 65,2 %. The research results confi rmed the validity of stopping the use of the Presynch protocol and completely transferring the dairy herd of cows to synchronization and insemination using the Double Ovsynch protocol.

Formation of a power-technological complex of renewable energy objects in the conditions of combination of sources

New possibilities of combining conventional and renewable energy sources under conditions of a power-technological complex of objects are identified. Sustainable development is substantiated by a theoretical model of an integration-balancing methodology for regulating the processes of combining energy sources in the cycle of formation and development of the complex. A mathematical model for the representation of evolutionary and abrupt processes of increasing energy efficiency has been adapted for simulation based on the approximation of step and generalized functions. A decrease in the imbalance of goals of the objects of conventional and renewable power industry in the formed complex is revealed over the period of four stages of the source integration and combination cycle. The simulation is implemented using the Data Science method. This provides an increase in the depth of analysis and quality of control based on the criteria of reducing the imbalance of the goals and increasing the efficiency of development processes. The possibilities of increasing the controllability of abrupt transition processes of objects to the conditions of combining energy sources and integrating with research and educational resources in the formed complex are substantiated

The use of the developed functional feed additive in the conditions of the equestrian complex of the Belgorod National Research University allowed to improve such training indicators of horses as frolic potential, endurance, as well as general health indicators of sports horses in training conditions in experimental groups of animals compared to control ones, such as positive correction of the intestinal microbiota and improvement of the activity of the gastrointestinal and hepatobiliary systems.

Optimized preparation of quassinoid-rich Eurycoma longifolia Jack phospholipid complex and its effects on oral bioavailability

Eurycoma longifolia Jack is a plant of the genus Eurycoma in Simaroubaceae. Eurycomanone is one of the main quassinoids of E. longifolia. Unfortunately, these quassinoids exhibit low bioavailability . In the present study, a phospholipid complex (TAF2-PC) was prepared to improve the oral bioavailability of TAF2 (Tongkat Ali Fraction 2). The complexation rate of eurycomanone and phospholipid was used as the index of success in the phospholipid complexes. The effects of reaction solvent, reaction temperature, drug concentration, drug-lipid ratio and reaction time on thecomplexation rate were investigated. Response Surface-Box-Behnken Design Method was performed to optimize the preparation technology and the pharmacokinetics of phospholipid complex of TAF2 were studied in rats. Our results showed that the optimum preparation condition of TAF2-phospholipid complex were as follows: reaction solvent, anhydrous ethanol; reaction time, 1 h; the ratio of TAF2 to phospholipid, 2.28; reaction temperature, 40.85 ℃; TAF2 concentration, 32.66 mg/ml; and complexation rate, 95.04 ± 0.4% (n=3).The results of pharmacokinetic study showed that the relative bioavailability was increased to 209.20% in the TAF2-phospholipid complex-treated rats.Thus,this phospholipid-complex-technique shows potential for enhancing oral bioavailability of poorly absorbed quassinoid-rich E. longifolia extract, TAF2.
