Objectives. Recently, there has been a tendency to increase the volume of high-viscosity heavy oils in the total volume of oil produced. The processing of these oils requires new technological approaches. This task is closely related to the need to increase the depth of oil refining. Among the appro...

In order to discuss the influence of reclamation on wetland soil P, a modified Hedley P fractionation method was employed to compare the variations of P fractions between wetland soil, farmland and abandoned farmland in Sanjiang Plain, China. It can be found that the content of total inorganic P (TP...

Pot experiments on three acid paddy soils with different P status were conducted to investigate the effects of P fertilizers on ryegrass growth and changes of soil P fractions after ryegrass planting. The results show that application of P fertilizers increased dry matter weight and P uptake of ryeg...

The aim of this study was to evaluate the effect of the iota, kappa and lambda carrageenan fractions on the physical properties and crystal structure of a fruit sorbet prepared from frozen mango fruits. During this study, physical properties such as density, cryoscopic temperature, osmotic pressure,...

In this paper, we calculate the Hausdorff dimension of some exceptional sets that emerge from specific constraints imposed on the partial quotients of continued fractions. In particular, we calculate the Hausdorff dimension of the sets \[ \Lambda _1=\Biggl \lbrace x\in (0,1): a_{n+1}(x)\ge \sum _{i=...

The article presents experimental data on regulatory effect of neutrophilokine helper fractions on the macrophage (Mph) functional activity in the course of antiplague immunity formation. It has revealed that these fractions content biologically active, low-molecular weight peptides. They stimulate...

The current study attempted to describe pre-service teachers’ symbolic-visual representation skills in adding and subtracting fractions. It specifically aimed to analyze the teachers’ ability to construct either a symbolic or visual representation in fraction operations. A case study was conducted b...

The purpose of this study was comparative analysis of normal biochemical composition of synovial fluid of knee and elbow human joints. Studies were performed on synovial fluid samples of 33 cadavers of suddenly dead people of both sexes (26 men and. 7 women) at the age of 23 to 79 years, without art...

The evolution of modern radiotherapy aligns seamlessly with the principles of Citius, Altius, Fortius—faster, higher, stronger— while embracing the Less is More philosophy. In recent years, the 5-fraction radiotherapy regimen has emerged as a transformative approach, offering shorter treatment dura...

ABSTRACT We produced maps of sediment fractions for the US Gulf of America (formerly Gulf of Mexico) and South Atlantic Bight at 1 km2 spatial resolution using compositional kriging. Quantitative tools were used to identify the optimal pixel size of the output map, which was produced using compositi...

Mosquito are well-known vectors that cause diseases particularly malaria and filariasis which are detrimental to human health. These vectors occur mainly in tropical countries where more than 2 billion people live in endemic regions with about one million deaths been claimed yearly from malaria and...

Film mulching and gravel mulching are effective methods for increasing crop yields in Northwest China but exacerbate soil organic carbon (SOC) mineralisation. Manure amendment is a viable method for offsetting carbon (C) losses from mulching. SOC stability is a key factor in determining the nutrient...
