Assessment of Soil Health Indicators Under the Influence of Nanocompounds and Bacillus spp. in Field Condition

Agricultural yield of major crops is low due to the injudicious use of chemical fertilizers that affects soil fertility and biodiversity severely and thereby affecting plant growth. Soil health is regulated by various factors such as physicochemical properties of the soil, availability of micro/macronutrients, soil health indicator enzymes and microbial diversity which are essential for agriculture productivity. Thus, it is required to draw attention towards an eco-friendly approach that protects the beneficial microbial population of soil. Application of different bioinoculants and agriusable nanocompounds has been reported to enhance soil quality with increased nutrient status and beneficial bacterial population, but additive effects of combined treatments on soil microbial population are largely unknown. The present study investigated the impact of nanozeolite and nanochitosan along with two Bacillus spp. on rhizospheric microbial flora and indicator enzymes to signify soil health under field conditions on maize. Soil health was ascertained by evaluating physicochemical analysis; total bacterial counts including N, P, and K solubilizing bacteria; and soil health indicator enzymes like fluorescein diacetate hydrolysis, alkaline phosphatase, β-glucosidase, dehydrogenase, amylase, and arylesterase. Change in copy number of 16S rRNA as a marker gene was used to quantify the bacterial population using quantitative PCR (qPCR) in different treatments. Our study revealed that nanocompounds with Bacillus spp. significantly (p < 0.05) enhanced total microbial count (16.89%), NPK solubilizing bacteria (46%, 41.37%, and 57.14%), and the level of soil health indicator enzymes up to twofold over control after 20, 40, and 60 days of the experiment. qPCR analysis showed a higher copy number of the 16S rRNA gene in treated samples, which also indicates a positive impact on soil bacterial population. This study presents a valuable approach to improve soil quality in combined treatments of nanocompounds and bioinoculants which can be used as a good alternative to chemical fertilizers for sustainable agriculture.

The Effects of Physical Exercise on Saliva Composition. A Comprehensive Review

Saliva consists of organic and inorganic constituents. During exercise, analysis of the saliva can provide valuable information regarding training stress, adaptation and exercise performance. The objective of the present article was to review the effect of physical exercise on saliva composition. The shift in the composition of the saliva, during and after a workout, reflects the benefits of exercise, its potential risks and the capability of the saliva to serve as a health indicator. The type and the frequency of training, the physical condition and the athletes’ general health influence the hormones, immunoglobulins and saliva enzymes. The correlation between saliva and physical exercise has to be further investigated and the available knowledge to be applied for the benefit of the athletes during sports activities.

Touring activities of Ukrderzhtsirk as a domain’s “health” indicator

The purpose of the article is to identify and analyze the effectiveness of the Ukrainian state circus arts system’s touring activities from the early 1990s. Methodology. The study analyses archival information on the Ukrderzhtsirk’s work. The historical-factographic method helps to record the results of the circus touring activities development. Comparative analysis allows detecting the specifics of the phenomenon, revealing its organizational and creative trends, and evaluating them. Scientific novelty. For the first time, the main trends of the Ukrainian state circus touring activities held since the early 1990s were revealed and characterized. Conclusions. The touring activities’ effectiveness is characterized by declining trends – something that corresponds to the general dynamics of the “post-Soiuzgostsirk” organizational and creative process. Probably one of the decline factors was that of the head organization’s inability to provide the circus system with a properly centralized management. Ukrderzhtsirk has some achievements, in particular, its own brand-name founding, business contacts establishing, organizing of abroad tours for Ukrainian programs. However, the state circus product’s export faces its decline, while the sector of import is not prospective as a foreign product is too expensive. Obviously the current organizational and creative approaches to foreign economic activities performing are in need to be revised. Keywords: Ukrainian circus arts, Soviet circus, touring, Ukrderzhtsirk, Soiuzgostsirk, circus arts enterprise, circus arts product.

Analysis of the Cases of Covid-19 and Environmental Health for 14 Municipalities of the UGRHIs Baixo Pardo/Grande and Pardo

Safety protocols emerged to minimize the spread of Covid-19 and are in force 20 months after the disease exists in Brazil. The occurrence of SARS-CoV2 can be analyzed by the local Environmental Health Indicator (ISA). The objective of this study was to analyze the mortality rate caused by Covid-19 about environmental and sanitary conditions in 14 municipalities in the state of São Paulo, located in the Baixo Pardo/Grande and Pardo UGRHIs. Data from covid-19 (total cases and deaths) were obtained by SEADE (2021) and research by Rezende (2021) and Alvares (2021) provided the ISA parameters. The municipalities were grouped by demographic density and those with up to 50 thousand inhabitants were selected. The fatality rate was obtained as the ratio of the number of deaths to the accumulated cases of Covid-19. Of the 14 selected municipalities, 57,1% met the research hypothesis (municipalities with higher ISA have a mortality rate at covid-19 below the national average) and seven of them are below 20 thousand inhabitants with mortality rates below 2,4 %. Studies based on data from Covid-19, socio-environmental parameters (schooling, income, age group) and social vulnerability conditions can contribute to a better interpretation of environmental health in the pandemic.
