It has been analyzed in this article the radioactivity concentrations of 226Ra, 232Th, 40K and radiological hazard parameters different types cements commonly used Poland available on Polish market. The are, particular, absorbed gamma dose rate, annual effective dose, radium equivalent activity, external index, alpha indices. radionuclide activities most important radionuclides have determined by gamma-ray spectrometry with use two kinds spectrometers operational parameters. One performed...
Abstract Air pollution emissions from road vehicles majorly contribute to particulate pollution. This poses significant threats the environment and human health. Road dust contains various potentially toxic elements, which, when exposed humans, can lead severe illnesses such as asthma, cardiovascular diseases, cancer. study assessed adult health risks through accidental ingestion, inhalation, dermal contact associated with heavy metals (Cr, Cu, Ni, Pb, Zn) in (with a fraction size < 0.1...
[Ortega (1985)][1] proposed a simple first-order differential equation to describe plant cell extension and, unlike the Lockhart ([Lockhart, 1965][2]), it takes into account elastic deformation of wall. [Cosgrove (1985)][3] and solved for
The measurements of the specific activity natural radioactive isotopes radium (226Ra), thorium (232Th) and potassium (40K) in chosen samples imported (China, Finland, Spain, India, Sweden) Polish (Izerski, Karkonosze, Siedlimowicki, Strzegomski, Strzelinski) granites were performed. carried out with 2 × 2" NaI(Tl) scintillation detector. measured on within following ranges: 5.8-312 [Bq kg-1], 5.5-189 kg-1] 109-1590 for 226Ra, 232Th 40K, respectively. Obtained concentrations allowed to...
In this contribution we deal with a new mathematical description of the response short-term coleoptile/hypocotyl expansion growth to temperature. Although interest both bio-mechanical basis elongation and temperature responses has been studied in plant biology biophysics for long time, yet question mode actions is very relevant still open. Here introduce simple idea that normal distribution, due central limit theorem (CLT), able report on temperature-dependent growth. The numerical fittings...
The time-irreversible cell enlargement of plant cells at a constant temperature results from two independent physical processes, e.g. water absorption and wall yielding. In such model growth starts with reduction in stress because irreversible extension the wall. expansion are spontaneous consequences this initial modification (the juvenile vacuolate, takes up expands). aspect arises Such theory expressed quantitatively by time-dependent equation was elaborated Lockhart 60's.The omit however...
Enlargement is one of the most fundamental activities plants, and there are many simultaneous processes involved. Several could be temperature-dependent, like metabolic cell wall sensitivity. A description plant elongation was elaborated by Lockhart in mid-60's last century form time-dependent differential equation. However, main disadvantage this approach missing environmental temperature at which growth takes place, as well lack representation factors influencing growth,...
The purpose of the present study was to determine suitability apple fibers (dietary fiber) as a raw material for granulate pellets production, an aspect waste management in sustainable agriculture processes.Apple are produced during agri-food processing apples.It is obtained from peas and can be further used diet supplement or animal feed purposes, reducing breeding costs.The moisturized with water mixture milk powder moisture content 16%.During tests, maximum pressure process determined all...
We consider the one-and two-photon e + -annihilation processes in an ultra-strong magnetic eld, at middly relativistic regime.Such conditions are reached neutron stars and especially magnetars, where electrons positrons ow within magnetar corona with average momenta of order p ∼ m0c, m0 electron mass, c light speed.We pay special attention to ratio total annihilation rates both processes.The well-known result is that limit → 0 for induction above critical Schwinger value B0 = 4.41×10 9 T,...
In this study we propose a simple mathematical model based on the equilibrium equation for materials deformed elastically. Owing to turgor pressure of cells, peripheral walls outer tissue are under tension, while extensible inner is compression. This well known properties growing multicellular plant organs can be derived from equilibrium. The analytic solutions may serve as good starting point modeling growth single cell or an organ.
The recent interest in positrons distribution the space revealed anomalous presence of high energetic positrons. There are different possible origins such positrons, including decay heavy particles dark matter, also pulsars or neutron stars. In our study we calculated annihilation properties electron – positron bound system superstrong magnetic fields expected for For this aim use solutions (relativistic) Bethe-Salpeter equation derived by L.B. Leinson and A. Perez [1]. results indicate...
The 2D Positronium (2D Ps) atom confined in the cave has been considered and its properties were compared with 3D located infinity square well potential. Basing on solution of Schrödinger equation for hydrogen wave function Ps was given. It allows us to calculate, instance angular correlation annihilation radiation (ACAR) such a system. shown that ACAR is much broad than bubble model.
