New types of irreducible second order Darboux transformations for the one dimensional Schrödinger equation are described. The main feature of such transformations is that the transformation functions have the eigenvalues grater then the ground state energy of the initial (or reference) Hamiltonian. When such a transformation is presented as a chain of two first order transformations, an interme...

The purpose of this study was to modify the sago grater roller, determine tool's effective capacity, calculate wet starch yield, and compare it with an unmodified machine. This research used tool modification experimental methods, including stages problem identification, refinement ideas. Based on results grating using Honda GX 160 gasoline motor 5.5 Hp 2200 rpm, average value capacity is 117.6...

We consider the dissipative charging process of quantum batteries in terms a collisional model, where are coupled to heat bath using non-energy preserving interactions. First, we show that for low temperatures collective can attain power increases polynomically with number batteries. The scaling find is $N^3$ that, while being grater than bound obtained unitary processes, it has lower efficienc...

In this work hybrid pectin-based biosorbents with secondary polysaccharide additives (gellan, carob and xanthan gum, ratio to pectin 1:1, 1:1 and 1:3, respectively) were obtained at two temperatures. The presence of these additives in prepared beads was confirmed by Raman spectra. The SEM micrographs show better homogeneity of blends and grater differences between structures of beads with vario...

A new code structure for spectral amplitude coding optical code division multiple access system, based on Double Weight (DW) code families is proposed. The DW code has a, fixed weight of two. Modified Double Weight (MDW) code possesses ideal cross-correlation properties and the weight can be any even number, which is grater than two. The MDW code possesses ideal cross-correlation properties and...

25-OH Vitamin D3 and 25-OH Vitamin D2 were determined by rapid, simple and validated LC/MS/MS method without using SPE and isotopic standard. The relative standard deviations (RSD) were found to be 3.1 and 2.8 % for 25-OH Vitamin D3 and 25-OH Vitamin D2, respectively. The correlation coefficient was grater than 0.99 for both analytes in the calibration range. The recoveries at 100 μg L concentr...

In this paper we consider generalization of procedure of construction of potential systems for systems of partial differential equations with multidimensional spaces of conservation laws. More precisely, for construction of potential systems in cases when dimension of the space of local conservation laws is greater than one, instead of using only basis conservation laws we use their arbitrary l...

Thalidomide is a sedative drug introduced to European markets on 1 October 1957 after extensive testing on rodent embryos to ensure its safety. Early laboratory tests in rodent populations showed that pregnant rodents could safely use it, so doctors prescribed Thalidomide to treat morning sickness in pregnant women. However, in humans [3] Thalidomide interfered with embryonic and fetal developm...

This study aims to develop a fish grater machine produce shredded on household scale. The development of this shredder considers getting the maximum capacity, minimum percentage losses, samples with short grade and middle size, rough size limited sources specified power. method used in research is manufacturing testing approach. Three types teeth (K-type, P-type, B-type) are main focus optimize...

Abstract Religiosity and spirituality provide cancer patients with strength confidence to face difficult situations during the process of seeking a cure, indicating that faith is an important element at this time. This systematic literature review analyzed national international scientific production assess whether religious spiritual practices facilitate therapeutic adherence improve quality l...
