Case Report: A Neocystostomy Perforation Presenting as a Gallstone

AbstractAn 83-year-old man, with a surgical history of radical cystectomy with simultaneous construction of a neobladder 13 years ago, presented clinically and radiologically as acute cholecystitis. Upon emergent exploratory laparotomy for his acute deterioration, a perforated neobladder was identified with its spilled stones in the gallbladder fossa, mimicking acute cholecystitis. This is the first case report of this presentation. Neobladder perforations should be considered in any patient who has undergone orthotopic bladder substitution, no matter how long it has been since the original reconstruction

A Survey on Retrieval of Mathematical Knowledge

We present a short survey of the literature on indexing and retrieval of mathematical knowledge, with pointers to 72 papers and tentative taxonomies of both retrieval problems and recurring techniques.Comment: CICM 2015, 20 page

EFFECT OF SOME FERTILIZATION TREATMENTS ON GROWTH, PRODUCTIVITY AND CHEMICAL CONSTITUENTS OF ROSELLE (HIBISCUS SABDARIFFA L.). PLANTS

A field experiment was conducted during 2015 and 2016 seasons at the Experimental Farm, Horticulture Dept., Fac. Agric., Benha Univ. to evaluate the effect of some fertilization treatments [10, 20 and 30 m3 compost/fed + bio fertilizer (nitrobein + phosphorein + potassiumag)] when compared with the recommended dose of chemical fertilizer in the  presence of micro-nutrients Fe + Mn + Zn foliar spraying (0.0, 50, 100 and 150 ppm) as well  as their interaction between them on some growth parameters, yield and chemical constituents of roselle (Hibiscus sabdariffa L.) plants during 2015 and 2016 seasons.   In this respect, all applied fertilizer treatments statistically and positively affected each of plant height, number of leaves, branches and fruits/plant, fresh and dry weight of leaves, branches and sepals/plant, sepals anthocyanin and vitamin-C content, leaf N, P, K, total carbohydrates, Fe, Zn and Mn content and total indoles but they decreased the values of total phenols contents, especially T2 treatment (the recommended dose of chemical fertilizer) or 30 m3 compost/fed + bio fertilizer (nitrobein + phosphorein + potassiumag), with the exception of sepals acidity with none significant differences in the two seasons. Also, all concentrations of micro-nutrients Fe + Mn + Zn significantly improved all the aforementioned parameters, especially using the high rates. Additionally, the highest values of plant height, number of leaves and branches/plant, fresh and dry weight of leaves and branches/plant, number of fruits/plant, seed yield/plant (g), leaf N, P, K, total carbohydrates, Fe, Zn and Mn content, total indoles as well as the lowest values of total phenols contents were recorded by the combined treatment between T2 recommended dose chemical fertilizer and 150ppm Fe + Mn + Zn acid in both seasons. Moreover, the combined treatment between T5 (30 m3) compost/fed + bio fertilizer  and 150 ppm Fe + Mn + Zn gave the highest values of fresh and dry weight of sepals/plant sepals acidity, sepals anthocyanin and vitamin-C content of roselle plants as compared with control in both seasons. Furthermore, the combined treatments of T4 (20 m3) compost/fed + bio fertilizer and 150 ppm Fe + Mn + Zn induced high significant increments in this concern in the two seasons. Consequently, it is preferable to treat roselle plants with the combined treatment between T2 (recommended dose of chemical fertilizer) or T5 (30 m3) compost/fed + bio fertilizer (nitrobein + phosphorein + potassiumag) and Fe + Mn + Zn at 150 ppm for enhancing growth and productivity of this plants

Conditional probabilities in quantum theory, and the tunneling time controversy

It is argued that there is a sensible way to define conditional probabilities in quantum mechanics, assuming only Bayes's theorem and standard quantum theory. These probabilities are equivalent to the ``weak measurement'' predictions due to Aharonov {\it et al.}, and hence describe the outcomes of real measurements made on subensembles. In particular, this approach is used to address the question of the history of a particle which has tunnelled across a barrier. A {\it gedankenexperiment} is presented to demonstrate the physically testable implications of the results of these calculations, along with graphs of the time-evolution of the conditional probability distribution for a tunneling particle and for one undergoing allowed transmission. Numerical results are also presented for the effects of loss in a bandgap medium on transmission and on reflection, as a function of the position of the lossy region; such loss should provide a feasible, though indirect, test of the present conclusions. It is argued that the effects of loss on the pulse {\it delay time} are related to the imaginary value of the momentum of a tunneling particle, and it is suggested that this might help explain a small discrepancy in an earlier experiment.Comment: 11 pages, latex, 4 postscript figures separate (one w/ 3 parts

Effects of Different Substituents on the Crystal Structures and Antimicrobial Activities of Six Ag(I) Quinoline Compounds

The syntheses and single crystal X-ray structures of [Ag(5-nitroquinoline)(2)]NO3 (1), [Ag(8-nitroquinoline)(2)]NO3 center dot H2O (2), [Ag(6-methoxy-8-nitroquinoline)(NO3)](n) (3), [Ag(3-quinolinecarbonitrile)(NO3)](n) (4), [Ag(3-quinolinecarbonitrile)(2)]NO3 (5), and [Ag(6-quinolinecarboxylic acid)(2)]NO3 (6) are described. As an alternative to solution chemistry, solid-state grinding could be used to prepare compounds 1 and 3, but the preparation of 4 and 5 in this way failed. The Ag(I) ions in the monomeric compounds 1, 2, 5, and 6 are coordinated to two ligands via the nitrogen atoms of the quinoline rings, thereby forming a distorted linear coordination geometry with Ag-N bond distances of 2.142(2)-2.336(2) angstrom and N-Ag-N bond angles of 163.62(13)degrees-172.25(13)degrees. The 1D coordination polymers 3 and 4 contain Ag(I) centers coordinating one ligand and two bridging nitrate groups, thereby forming a distorted trigonal planar coordination geometry with Ag-N bond distances of 2.2700(14) and 2.224(5) angstrom, Ag-O bond distances of 2.261(4)-2.536(5) angstrom, and N-Ag-O bond angles of 115.23(5)degrees-155.56(5)degrees. Hirshfeld surface analyses of compounds 1-6 are presented as d(norm) and curvedness maps. The d(norm) maps show different interaction sites around the Ag(I) ions, i.e., Ag center dot center dot center dot Ag interactions and possible O-H center dot center dot center dot O, C-H center dot center dot center dot O, C-H center dot center dot center dot N, and C-H center dot center dot center dot C hydrogen bonds. Curvedness maps are a good way of visualizing pi-pi tacking interactions between molecules. The antimicrobial activities of compounds 1, 2, and 6 were screened against 15 different multidrug-resistant strains of bacteria isolated from diabetic foot ulcers and compared to the antimicrobial activities of the clinically used silver sulfadiazine (SS). Compound 2 showed activity similar to SS against this set of test organisms, being active against all strains and having slightly better average silver efficiency than SS (5 vs 6 mu g Ag/mL). Against the standard nonresistant bacterial strains of Staphylococcus aureus, Pseudomonas aeruginosa, Proteus mirabilis, and Streptococcus pyogenes, compound 1 performed better than silver nitrate, with an average MIC of 6 mu g Ag/mL versus 18 mu g Ag/mL for the reference AgNO3. Electrospray ionization mass spectrometry (ESI-MS) analyses of compounds 3 and 6 in DMSO/MeOH confirm the two-coordinated Ag+ complexes in solution, and the results of the H-1 NMR titrations of DMSO solutions of 5-nitroquinoline and 8-nitroquinoline with AgNO3 in DMSO suggest that 5-nitroquinoline is more strongly coordinated to the silver ion
