Parkes Pulsar Timing Array constraints on ultralight scalar-field dark matter

It is widely accepted that dark matter contributes about a quarter of the critical mass-energy density in our Universe. The nature of dark matter is currently unknown, with the mass of possible constituents spanning nearly one hundred orders of magnitude. The ultralight scalar field dark matter, consisting of extremely light bosons with m ∼ 10^(−22)  eV and often called “fuzzy” dark matter, provides intriguing solutions to some challenges at sub-Galactic scales for the standard cold dark matter model. As shown by Khmelnitsky and Rubakov, such a scalar field in the Galaxy would produce an oscillating gravitational potential with nanohertz frequencies, resulting in periodic variations in the times of arrival of radio pulses from pulsars. The Parkes Pulsar Timing Array (PPTA) has been monitoring 20 millisecond pulsars at two- to three-week intervals for more than a decade. In addition to the detection of nanohertz gravitational waves, PPTA offers the opportunity for direct searches for fuzzy dark matter in an astrophysically feasible range of masses. We analyze the latest PPTA data set which includes timing observations for 26 pulsars made between 2004 and 2016. We perform a search in this data set for evidence of ultralight dark matter in the Galaxy using Bayesian and Frequentist methods. No statistically significant detection has been made. We, therefore, place upper limits on the local dark matter density. Our limits, improving on previous searches by a factor of 2 to 5, constrain the dark matter density of ultralight bosons with m ≤ 10^(−23)  eV to be below 6  GeV cm^(−3) with 95% confidence in the Earth neighborhood. Finally, we discuss the prospect of probing the astrophysically favored mass range m ≳ 10^(−22)  eV with next-generation pulsar timing facilities

Sensitivity of the phenoxy derivatives of 2,4-dihydro-5H-[1,2,3]triazolo[4,5-d]pyrimidin-5-ones to acidic and basic stimuli

Herein we report the research on the sensitivity of six hydroxy derivatives of dihydrotriazolopyrimidines (HO-DTP) to acids and bases. The UV/Vis and fluorescence spectra of these compounds were investigated with the addition of the acids and bases. Spectral data revealed the strong red shifts for emission and absorption maxima in the presence of KOH and NaOH. Moreover, two DTPs demonstrated strengthening of the emission intensity. The obtained results and data published in our previous paper demonstrated the strong and selective sensory response of DTPs to the acids and bases and elucidated relationships between the structure and sensitivity to the environment. This finding allowed us to manage these properties by introducing the combination of substituents and functionalities into the heterocyclic core. Thus, investigations demonstrated the potential of the application of DTPs as chemo- and fluorosensors for selective detection of acids and bases

THE GERMAN POWER INDUSTRY UNDER CONDITIONS OF ENERGY CRISIS: THE PRICE OF RELIABILITY. PART 1

Hereafter is a research of a situation in German electric power production and consumption in view of an energy crisis. The purpose of this work is to study how crisis effects the general energy field operating, as well as the federal government’s decisions concerning it. Included is statistical data on the changes in power production both in Germany and the EU. Federal government had to adapt energy policy to the crisis, adjusting it in almost every of its aspects, which are traditionally regarded as follows: stability – economics – ecology. Thus the article is divided into three parts accordingly, each of them further exploring on suitably matching government measures, new policy trends or conservation. In 2022 the task of providing continuously secure energy supply became especially significant. Since gas-fueled power generation is a key to continuous security of energy transition-oriented system, government action was focused on filling gasholders, in regard to growing tensions with Russian Federation

THE GERMAN POWER INDUSTRY UNDER CONDITIONS OF ENERGY CRISIS: THE PRICE OF RELIABILITY. PART 2

The first part of the paper includes a discussion on the impact the energy crisis had on the German power industry and what measures the government has taken to ensure a reliable energy supply. Reliability, efficiency and sustainability make up the «Triangle of Aims» of the energy policy of a country. The second half of the paper is dedicated to the measures that the federal government took during the acute phase of the energy crisis in terms of the second aim. We discuss three main aspects. Firstly, we show the changes in the structure of pricing for two categories of consumers: householders and non-household consumers. Secondly, we demonstrate the formation of the price on the electricity spot market. Lastly, we elaborate on the ways the government could influence the level of prices and to what extent these possibilities have been used in accordance with the rules of the European Union. The crisis showed the readiness of the government to take costly measures such as zeroing the taxes that are due under the Renewable Energy Act, giving a lump sum payment to the employed, the students and the pensioners, refusing to increase the cost of CO2 emission certificates, providing business benefits and subsidies and enforcing a gas and electricity price brake. For the period after the end of the «price brake», the government is considering subsidizing prices for export-oriented production that implements the climate goals. These plans confirm the existence of the «shadow budget» that was formed for overcoming the consequences of the pandemic

Dynamics of water separation in destruction of water-in-oil emulsions

The dynamics of drop formation and settling processes in breaking water-in-oil emulsions of the West Siberian oil fields was experimentally studied. The investigation results of drop formation in the water-in-oil emulsions were presented. The residual water content in oil was determined after the settling process at the varied initial water content, temperature, and hydrodynamic conditions of emulsion formation

Determination of Safety Indicators in the Developed Muffins with Non-traditional Raw Materials

The aim of research is studying the effect of unconventional raw materials (buckwheat, oatmeal, rye, corn, milk whey, skimmed milk powder, propolis, flower pollen, bean powder, sesame oil, pumpkin seed oil, walnut oil, walnut kernels, candied fruit mixes (apple-cherry fruits of bilberries, natural honey with floral pollen, natural honey with propolis) for the quality and safety of new muffins. The article analyzes the results of the study of the quality and safety indicators of muffins of improved composition, manufactured using non-traditional raw materials. For the preparation of new types of muffins, part of the wheat flour was replaced with buckwheat, corn, oat, milk whey, skimmed milk powder and additives of vegetable origin. Margarine has been replaced by vegetable oils. It has been established that flour confectionery products have high organoleptic properties. From the physico-chemical parameters, the mass fraction of total sugar was determined, which ranged from 28.17 % to 33.07 %, the mass fraction of fat – 16.2–20.66 %, the mass fraction of moisture – 18.0–22.0, mass fraction of ash – 0.03–1.3 %, alkalinity – 0.03–1.8°, the content of toxic elements (copper, zinc, lead, cadmium, arsenic, mercury) and microbiological indicators were also determined. Based on the data obtained as a research result, the expediency of using non-traditional raw materials to expand the range of flour confectionery products, in particular muffins is substantiated
