Exact solution of Schrodinger equation for modified Kratzer's molecular potential with the position-dependent mass

Exact solutions of Schrodinger equation are obtained for the modified Kratzer and the corrected Morse potentials with the position-dependent effective mass. The bound state energy eigenvalues and the corresponding eigenfunctions are calculated for any angular momentum for target potentials. Various forms of point canonical transformations are applied. PACS numbers: 03.65.-w; 03.65.Ge; 12.39.Fd Keywords: Morse potential, Kratzer potential, Position-dependent mass, Point canonical transformation, Effective mass Schr\"{o}dinger equation.Comment: 9 page

Potential algebra approach to position dependent mass Schroedinger equation

It is shown that for a class of position dependent mass Schroedinger equation the shape invariance condition is equivalent to a potential symmetry algebra. Explicit realization of such algebras have been obtained for some shape invariant potentials

The energy eigenvalues and the corresponding eigenfunctions of the one-dimensional Klein-Gordon equation with q-parameter Poschl-Teller potential are analytically obtained within the position-dependent mass formalism. The parametric generalization of the Nikiforov-Uvarov method is used in the calculations by choosing a mass distribution.Comment: 10 page

Thirty years of heterogeneous vehicle routing

It has been around thirty years since the heterogeneous vehicle routing problem was introduced, and significant progress has since been made on this problem and its variants. The aim of this survey paper is to classify and review the literature on heterogeneous vehicle routing problems. The paper also presents a comparative analysis of the metaheuristic algorithms that have been proposed for these problems

Urinothorax Caused by Xanthogranulomatous Pyelonephritis

Xanthogranulomatous pyelonephritis is a rare form of chronic pyelonephritis that generally afflicts middle-aged women with a history of recurrent urinary tract infections. Its pathogenesis generally involves calculus obstructive uropathy and its histopathology is characterized by replacement of the renal parenchyma with lipid filled macrophages. This often manifests as an enlarged, nonfunctioning kidney that may be complicated by abscess or fistula. This case details the first reported case of xanthogranulomatous pyelonephritis complicated by urinothorax, which resolved on follow-up chest X-ray after robot-assisted nephrectomy

Coherent States for the Non-Linear Harmonic Oscillator

Wave packets for the Quantum Non-Linear Oscillator are considered in the Generalized Coherent State framerwork. To first order in the non-linearity parameter the Coherent State behaves very similarly to its classical counterpart. The position expectation value oscillates in a simple harmonic manner. The energy-momentum uncertainty relation is time independent as in a harmonic oscillator. Various features, (such as the Squeezed State nature), of the Coherent State have been discussed

DJELOVANJE BAKTERIJSKOG CJEPIVA HOMOFERMENTACIJSKE MLIJEČNE KISELINE NA FERMENTACIJU I AEROBNU STABILNOST KUKURUZNE SILAŽE NAKNADNE SJETVE

This study was carried out to determine the effects of homofermentative lactic acid bacterial inoculant on the fermentation and aerobic stability of second crop maize silages. Maize was harvested at the milk stage. Inoculant -1174 (Pioneer®,USA) was used as homofermentative lactic acid bacterial inculant. Inoculant was applied 6.00 log10 cfu/g silage levels. Silages with no additive served as controls. After treatment, the chopped maize was ensiled in the PVC type laboratory silos. Three silos for each group were sampled for chemical and microbiological analysis on days 2, 4, 7, 14, 21, 28 and 56 after ensiling. At the end of the ensiling period, all silages were subjected to an aerobic stability test for 14 days. Neither inoculant improved the fermentation parameters of second crop maize silages. At the end of the ensiling period, inoculant increased lactobacilli and decreased yeast and mold numbers of silages. Inoculant treatment did not affect aerobic stability of silages.Svrha rada je bila utvrditi djelovanje bakterijskog cjepiva homofermentacijske mliječne kiseline na fermentaciju i aerobnu stabilnost kukuruzne silaže naknadne sjetve Kukuruz je bran u mliječnom stadiju. Upotrijebljeno je cjepivo 1174 (Pioneer®, SAD) kao homofermentacijsko cjepivo mliječne kiseline. Cjepivo je primijenjeno 6.00 log10 cfu/g razina silaže. Silaže bez aditiva poslužile su kao kontrolne. Nakon tretmana isjeckan kukuruz je siliran u laboratorijskom silosu tipa PVC. Izabrana su tri silosa za svaku skupina za kemijsku i mikrobiološku analizu 2., 4., 7., 14., 21., 28. i 56. dana nakon siliranja. Na kraju razdoblja siliranja sve su silaže podvrgnute 14 dana testiranju aerobne stabilnosti. Niti jedno cjepivo nije poboljšalo parametre fermentacije kukuruzne silaže. Na kraju siliranja cjepivo je povećalo laktobacile i smanjilo broj kvasaca i plijesni u silažama. Tretiranje cjepivom nije djelovalo na aerobnu stabilnost silaže

Identification of four proteins from the small subunit of the mammalian mitochondrial ribosome using a proteomics approach

Proteins in the small subunit of the mammalian mitochondrial ribosome were separated by two-dimensional polyacrylamide gel electrophoresis. Four individual proteins were subjected to in-gel Endoprotease Lys-C digestion. The sequences of selected proteolytic peptides were obtained by electrospray tandem mass spectrometry. Peptide sequences obtained from in-gel digestion of individual spots were used to screen human, mouse, and rat expressed sequence tag databases, and complete consensus cDNAs for these species were deduced in silico. The corresponding protein sequences were characterized by comparison to known ribosomal proteins in protein databases. Four different classes of mammalian mitochondrial small subunit ribosomal proteins were identified. Only two of these proteins have significant sequence similarities to ribosomal proteins from prokaryotes. These proteins are homologs to Escherichia coli S9 and S5 proteins. The presence of these newly identified mitochondrial ribosomal proteins are also investigated in the Drosophila melanogaster, Caenorhabditis elegans, and in the genomes of several fungi

Evaluating the efficacy of a self-help compassionate journal keeping intervention in addressing experiences of shame, low self-compassion, fear of self-compassion and disorder symptoms in individuals with an eating disorder

The current study examined whether self-compassion journal keeping as a self-help intervention for 2-weeks is able to address experiences of shame, low self-compassion, fear of compassion and disorder symptoms in individuals with an eating disorder. 41 participants recruited from an eating disorders service were randomly allocated to two conditions; experimental and control condition. Participants in the experimental condition recorded a self-compassion diary over 2weeks using self-help material and recorded a log of the amount of time they spent writing in their journals. Participants in the control condition remained on the waiting list. All participants completed 6 measures at the start of the experiments and repeated these at the end of the 2weeks. The findings showed that shame and low-compassion experienced as a personality trait at the core of one’s self identity and the characteristics and the severity of one’s eating psychopathology cannot be addressed within a 2 week period using a self-help intervention designed to cultivate self-compassion. Momentary experiences of low compassion and shame and fear of compassion on the other hand can be addressed within this time period using this intervention. Specifically, the findings suggested that CFT informed interventions may have a degree of therapeutic significance for individuals with an eating disorder. The findings also suggested that low intensity interventions such as self-help may be appropriate for this clinical group and can be considered as an alternative to no treatment waiting lists
