The article is based on field research, existing literature, and samples of herbarium kept in the National Herbarium fund (TASH) Poa bulbosa L. The distribution maps and productivity indicators in the flora of Uzbekistan are presented. As you know, Poa bulbosa L. is considered the wild relative of cultural plants, as a forage plant, it is a plant with high protein value. In the course of research during 2021-2022, in 16 areas, the yield indicators of the species were determined. In the studied research areas, indicators of the total weight of plant bushes (on the account of wet mass) and, respectively, the volume of plant biomass (on the account of dry mass, the upper part of 25%) were determined. According to him, it was determined that the average yield of the plant the wet mass is 14669.8 kg/ha, and the average yield of the plant the dry mass in areas of total 244.0 ha in the total area is 63172.5 kg.

Ferula L. is a perennial herbaceous plant belonging to the family Apiaceae Lindl. (Umbelliferae). Our research was carried out on the territory of Navoi region. The article presents an ecological analysis of the species of the Ferula L. in Navoi region. The species of genus Ferula mostly grows in mountainous regions and some are distributed in arid climates. According to that 15 species of the genus were found in the Navoi region, most of these species are considered to be plants that contain tar as well as have a strong medicinal property. In various parts of the world, different species of Ferula have been used in traditional medicine. In the course of studies, it was found that the species has medicinal, essential-oil, honey-j.icy, nutritious, and fodder properties. According to ecological analysis, the genus Ferula grows Rocky, gravelly, fine-grained slopes and ridges of mountains, scree, rocks, outcrops of variegated rocks, rocky slopes, sandy, clay and gravelly deserts, foothill plains, fine-grained slopes. Considered rare, Ferula kyzylkumica Korovin is listed in the Red Book of the Republic of Uzbekistan, while Ferula nuratavica Pimenov is an endemic plant of the Aktau ridge.

The effects of the gravitational redshift of gravitons upon spiral galaxy rotation energy are compared to the standard mass to light analyses in obtaining rotation curves. The derivation of the total baryonic matter compares well with the standard theory and the rotation velocity is matched to a high precision. The stellar mass distributions obtained from the fit with graviton energy loss are used to derive the surface brightness magnitudes for the galaxies, which agree well with the observed measurements. In a new field of investigation, the graviton theory is applied to the observations of gravitational lenses. The results of these applications of the theory suggest that it can augment the standard methods and may eliminate the need for dark matter.

This paper quantifies the regional economic contributions of coal exports from the US using a case study of Signal Peak Energy in Montana. Two methods of estimating economic contributions are compared, contribution and impact analysis. The latter is adopted because the industry impact analysis is more accurate, especially since it is based upon accounting records from Signal Peak. Our estimates of regional economic and fiscal impacts do not vary significantly with the price of coal because we explicitly account for swings in royalty income. Our analysis finds that Signal Peak Energy supports 678 j.bs, over $55 million in tax revenues, more than $90 million in royalties, $111.7 million in value added, and $62.3 million in labor income. Curtailing or halting Signal Peak’s coal production for environmental reasons as some environmental groups have argued would eliminate these economic contributions.

Problem: The Fresnel equations describe the proportions of reflected and transmitted light from a surface, and are conventionally derived from wave theory continuum mechanics. Particle-based derivations of the Fresnel equations appear not to exist. Approach: The obj.ctive of this work was to derive the basic optical laws from first principles from a particle basis. The particle model used was the Cordus theory, a type of non-local hidden-variable (NLHV) theory that predicts specific substructures to the photon and other particles. Findings: The theory explains the origin of the orthogonal electrostatic and magnetic fields, and re-derives the refraction and reflection laws including Snell’s law and critical angle, and the Fresnel equations for s and p-polarisation. These formulations are identical to those produced by electromagnetic wave theory. Contribution: The work provides a comprehensive derivation and physical explanation of the basic optical laws, which appears not to have previously been shown from a particle basis. Implications: The primary implications are for suggesting routes for the theoretical advancement of fundamental physics. The Cordus NLHV particle theory explains optical phenomena, yet it also explains other physical phenomena including some otherwise only accessible through quantum mechanics (such as the electron spin g-factor) and general relativity (including the Lorentz and relativistic Doppler). It also provides solutions for phenomena of unknown causation, such as asymmetrical baryogenesis, unification of the interactions, and reasons for nuclide stability/instability. Consequently, the implication is that NLHV theories have the potential to represent a deeper physics that may underpin and unify quantum mechanics, general relativity, and wave theory.

Background: The Air Force Health Study collected reproductive outcomes for live-born children of male Air Force veterans of the Vietnam War. Methods: Dioxin values for participants were obtained from blood samples. Analyses were conducted of occurrence of 16 specific categories of birth defects and developmental disabilities. Children were categorized as conceived before and after the start of participants’ Vietnam War service. Children conceived before the start of Vietnam War service were treated as being conceived when their fathers had unquantifiable dioxin values. Children conceived after the start of Vietnam War service for participants with missing dioxin values were excluded from primary analyses, but were used to assess the impact of their exclusion on conclusions. Correlation between values for specific categories for multiple children fathered by the same participant was accounted for. The dose-response relationship was treated as a step function increasing for dioxin values larger than adaptively identified individual thresholds changing with the specific category. Results: For 15 of 16 specific categories, the probability of occurrence increased substantially for a sufficiently high dioxin level above identified thresholds. Exclusion of children due to missing dioxin likely did not affect these results. Conclusions: Results supported the conclusion of substantial adverse effects on a wide variety of specific categories of birth defects and developmental disabilities due to sufficiently high exposures to dioxin, a toxic contaminant of Agent Orange used for herbicide spraying in the Vietnam War. Results may hold more generally, but might also have been affected by a variety of limitations.

The experimental and analytical investigation was conducted on a solar-powered single-effect distillation (SED). The evaporator was designed to be an electrical evaporator as opposed to the steam evaporator that existed previously. Using sun-tracking solar panels, the electrical evaporator in the designed distillation unit was powered by solar energy. Approximately 20 kWh was utilized by the small-scale distillation apparatus. This type of design is mobile, so remote areas and countries with fragile economies can utilize it on a small or large scale. Utilizing the principles of energy and mass conservation, the amount of distillate water and power required for a single unit was determined, at the low salinity (2200 PPM) with fixed boiling point temperature (Tb = 75˚C), the unit performance is approx. 98.4%. The experimental results and those derived from a mathematical model were compared, and both showed strong accord. Using engineering equation solver (EES) software, a computer program was developed for this research scenario.
