Unusual presentation of late recurrence renal malignancy

Introduction: Late recurrence of renal cell carcinoma is rare and mostly of clear cell histology. The objective of our study was to report our case of late recurrence of papillary RCC.Observation: Seventy year old female patient was presented to our department, more than 7 years post radical nephrectomy for moderate risk RCC. The presentation was persistent localized abdominal pain and proved by immunohistochemistry to be a metastatic papillary RCC.Conclusion: Any symptomatic patient, with history of previous radical nephrectomy, should have recurrent cancer considered in his differential diagnosis

Nuclear Shape Transition, Triaxiality and Energy Staggering of gamma Band States for Even-Even Xenon Isotopic Chain

The positive-parity states of even-even Xe nuclei are investigated within the framework of modified O(6) limit of the interacting boson model (IBM1). The effective three-body interaction [QQQ] where Q is the IBM O(6) quadrupole operator is introduced to exhibit the triaxiality nature. The shape of nuclear surface is described by the deformation parameters beta, gamma by using the intrinsic coherent state. The potential energy surfaces (PES) of the transition U(5)-Triaxiality-O(6) are calculated and analyzed and the critical phase transition points are identified. For each nucleus a fitting procedure is adopted to get the best model parameters by fitting some selected calculated energy levels and B(E2)transition rates ratios with experimental ones. These ratios are analyzed because they serve as effective order parameters in the shape phase transition. The nuclei in Xe isotopic chain evolve from spherical vibrator U(5) to gamma-soft rotor O(6) by increasing the boson number from N=3 (heavy isotope 132Xe) to N=10 (light isotope 120Xe) and the isotope 126Xe represent the critical nucleus. The nucleus 128Xe has triaxial nature. To deal with high spin states in gamma band in 118- 128Xe isotopic chain to investigate and exhibit the odd-even spin energy staggering, we introduce the two parameters collective nuclear softness rotor model (CNS2). Three different staggering indices depending on the dipole transitions linking the two families of spins and the quadrupole transitions within each spin family are considered. Strong odd-even spin energy staggering has been seen. As a link between the IBM and CNS2 models we observed that the energy difference between the gamma-band and ground state band normalized to decreases with increasing the mass numberComment: 20 pages,4 tables, 7 figures and 59 reference

Information technology in the British and Irish undergraduate accounting degrees

Using an online questionnaire and a series of semi-structured interviews, this study seeks the perceptions ofaccounting educators and professional accounting bodies in the UK and Ireland on the status quo of technologicaldevelopments within accounting curricula and the factors influencing this status quo. Findings suggest a fairlywidespread view that technological developments represent an important area that should be covered acrossaccounting curricula, to expose changes in the marketplace and to enhance the employability of graduates.However, it is still a peripheral component in accounting curricula, with no clear agenda for change. Professionalaccounting bodies seem to play a hegemonic inhibiting role through accreditation requirements although otherinhibitors were reported such as lack of competent/interested staff and lack of time/space in already overloadedsyllabi

Annealing Effects on Structural and Optical Properties of Ge10Sb30Se60 Thin Film

The optical constants of as-prepared and thermally annealed Ge10Sb30Se60thin films were determined. Effect of heat treatment on the structure and optical properties of Ge10Sb30Se60 thin films in the range between the glass transition and crystallization temperature have been investigated. The glass transition and crystallization temperature of the synthesized sample was measured by non- isothermal DSC measurements. The microstructure and optical properties of these films were characterized by UV-VIS spectrum, scanning electron microscope (SEM) and X-ray diffraction (XRD). The optical band gap for as-prepared and annealed films have been calculated using Taucs low from the optical transmission and reflection spectra. The results indicate that the optical band gap Eopt increases when the annealing temperature (Ta) is lower than the glass transition temperature (Tg), while decreases with further increase of Ta. The XRD studies show that the as-prepared film is amorphous in nature, but the crystalline improved with increasing the annealing temperature. Furthermore the particle size and crystalline increases while the dislocation and strains decreases with increasing the annealing temperature. Thermal annealing was found to be accompanied by structural effects, which in turn, lead to change in the optical constants. The obtained results were explained in terms of the Mott and Davis model for amorphous materials and amorphous to crystalline structure transformations

Capability of the Invasive Tree Prosopis glandulosa Torr. to Remediate Soil Treated with Sewage Sludge

Sewage sludge improves agricultural soil and plant growth, but there are hazards associated with its use, including high metal(loid) contents. An experimental study was conducted under greenhouse conditions to examine the effects of sewage sludge on growth of the invasive tree Prosopis glandulosa, as well as to determine its phytoremediation capacity. Plants were established and grown for seven months along a gradient of sewage sludge content. Plant traits, soil properties, and plant and soil concentrations of N, P, K, Cd, Pb, Cu, Ni, Zn, Cr, Co, As, and Fe were recorded. The addition of sewage sludge led to a significant decrease in soil pH, and Ni, Co, and As concentrations, as well as an increase in soil organic matter and the concentrations of N, P, Cu, Zn, and Cr. Increasing sewage sludge content in the growth medium raised the total uptake of most metals by P. glandulosa plants due to higher biomass accumulation (taller plants with more leaves) and higher metal concentrations in the plant tissues. P. glandulosa concentrated more Cd, Pb, Cu, Zn, and Fe in its below-ground biomass (BGB) than in its above-ground biomass (AGB). P. glandulosa concentrated Ni, Co, and As in both BGB and AGB. P. glandulosa has potential as a biotool for the phytoremediation of sewage sludges and sewage-amended soils in arid and semi-arid environments, with a potential accumulation capability for As in plant leaves

IT governance matter: A structured literature review

The aim of this paper is to critically explore information technology governance (ITG) context, its consequences, its various aspects, its determinants, disclosure, maturity, and challenges. There are some motivations that urge the researchers to carry out this study. First, the review of prior relevant literature reveals a limited number of studies addressing the IT governance context, its consequences, its various aspects, its determinants, and challenges. Second, very little is known about the potential implications of IT governance within the business and how it is significant to the decision-makers (e.g., shareholders, board of directors, executives, etc.). Finally, little research employs the structured literature review (SLR) approach to critically discuss and analyze the IT governance context with its various aspects. The systematic and structured literature review has been employed for a critical analysis of the previous studies on IT governance. It is found that effective ITG has a positive impact on the firm performance in consistent with Altemimi and Zakaria (2017), Hulme (2012). Additionally, it is concluded that there is a positive association between ITG, the trustworthiness and the level of financial disclosure agreeing with (Raghupathi, 2007; Ali & Green, 2007). It is also concluded that the level of ITG disclosure is higher within firms in Europe (67%) than in the US (49%) complementing with Joshi et al. (2013). The adoption of the SLR methodology enables this paper to derive unbiased empirical insights and critique into the current ITG research and to identify possible directions for future ITG research, which may possibly be of interest to the academics, regulators, and professional bodies (e.g., shareholders, board of directors, executives, etc.)
