ammo Our Holy Father Ammon of Egypt (4th c) By www.ancientfaith.com Published On :: 2020-06-28T17:31:17+00:00 "Our holy Father Ammon's parents died in his childhood. He was brought up by an uncle, who made him marry when he was still very young. On the night of his wedding, as soon as he and his wife retired to the bridal chamber, Ammon took up the holy Scriptures and read the passage in the Epistle to the Corinthians where the Apostle speaks of the disadvantages of marriage because of all the troubles and cares that come with it, while virgins consecrated to the Lord can devote themselves without distraction to prayer and to spiritual labour. Both spouses took the following words literally: From now on, let those who have wives be as though they had none... and those who deal with the world, as though they had no dealings with it (1 Cor. 7:29,31). They decided to remain in their virginity and to retire together to a desert place where they could give themselves over to prayer and fasting. They set out for the mountain of Nitria, some way from Alexandria, and settled in a little hut there. But, living together as man and woman, they soon realized the inexpedience of tempting nature head-on and of provoking the attacks of demons. They parted company, therefore, each to live separately in ascesis. Ammon never used wine or oil but lived only on dry bread that he ate every two or three days. "His manner of life was pleasing to the Lord, and a great many brethren who wanted to embrace the monastic life soon came to join him. When a new aspirant arrived, Ammon would immediately let him have his own cell with everything in it, and the other brethren would secretly bring provisions to the newcomer or whatever else might be useful. This showed that fraternal love was first among the laws observed in this ever-growing brotherhood. In a few years, under the direction of Ammon, the desert of Nitria was transformed into a veritable city. Some of the brethren now wanted to build their cells at a distance where they could live in greater solitude, so when one day Saint Antony the Great came to visit him, Abba Ammon asked his advice about the place to choose. At the ninth hour, after taking a scanty meal together, they walked in the desert until sunset, when they set up a cross at the place they had reached, so that those who wanted to could build their cells there with the blessing of the two Elders. 'In this way,' Abba Antony said, 'the brethren coming from Nitria, after a meal at the ninth hour, to see those who are here, will meet them at this moment. And if those who leave here to go to Nitria do the same, they will not lose their hesychia (stillness).' This was how the desert of Kellia ('the Cells') came to be established almost twelve miles from Nitria. More than six hundred monks were soon living there, each in his own cell. "Saint Ammon and Saint Antony were united in a deep spiritual friendship. When Abba Ammon gave up his soul in peace to the Lord at Nitria, Antony, far away on his mountain, broke off the conversation he was having with some monks and, in ecstasy, saw the soul of Ammon going up to Heaven accompanied by the joyful hymns of a multitude of angels. Among other words inspired by the Holy Spirit, Saint Ammon said, 'Bear with everyone as God bears with you'." (Synaxarion) Full Article

ammo Automatic pectoral muscles and artefacts removal in mammogram images for improved breast cancer diagnosis By www.inderscience.com Published On :: 2024-11-08T23:20:50-05:00 Breast cancer is leading cause of mortality among women compared to other types of cancers. Hence, early breast cancer diagnosis is crucial to the success of treatment. Various pathological and imaging tests are available for the diagnosis of breast cancer. However, it may introduce errors during detection and interpretation, leading to false-negative and false-positive results due to lack of pre-processing of it. To overcome this issue, we proposed a effective image pre-processing technique-based on Otsu's thresholding and single-seeded region growing (SSRG) to remove artefacts and segment the pectoral muscle from breast mammograms. To validate the proposed method, a publicly available MIAS dataset was utilised. The experimental finding showed that proposed technique improved 18% breast cancer detection accuracy compared to existing methods. The proposed methodology works efficiently for artefact removal and pectoral segmentation at different shapes and nonlinear patterns. Full Article

ammo Atypical phase transition, twinning and ferroelastic domain structure in bis(ethylenediammonium) tetrabromozincate(II) bromide, [NH3(CH2)2NH3]2[ZnBr4]Br2 By journals.iucr.org Published On :: 2024-11-04 Single-crystal growth, differential thermal analysis (DTA), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), X-ray structural studies and polarized microscopy observations of bis(ethylenediammonium) tetrabromozincate(II) bromide [NH3(CH2)2NH3]2[ZnBr4]Br2 are presented. A reversible phase transition is described. At room temperature, the complex crystallizes in the monoclinic system. In some cases, the single crystals are twinned into two or more large domains of ferroelastic type with domain walls in the (100) crystallographic plane. DTA and DTG measurements show chemical stability of the crystal up to ∼538 K. In the DSC studies, a reversible isostructural phase transition was revealed at ∼526/522 K on heating/cooling run, respectively. Optical observation on the heating run reveals that at the phase transition the plane of twinning (domain wall) does not disappear and additionally the appearance of a new domain structure of ferroelastic type with domain walls in the planes (101), (101), (100) and (001) is observed. The domain structure pattern is preserved after cooling to the room-temperature phase and the symmetry of this phase is unchanged. Full Article text

ammo Bis(ethylenediammonium) μ-ethylenediaminetetraacetato-1κ3O,N,O':2κ3O'',N',O'''-bis[trioxidomolybdate(VI)] tetrahydrate By journals.iucr.org Published On :: 2024-07-12 The title compound, (C2H10N2)2[(C10H12N2O8)(MoO3)2]·4H2O, which crystallizes in the monoclinic C2/c space group, was obtained by mixing molybdenum oxide, ethylenediamine and ethylenediaminetetraacetic acid (H4edta) in a 2:4:1 ratio. The complex anion contains two MoO3 units bridged by an edta4− anion. The midpoint of the central C—C bond of the edta4− anion is located on a crystallographic inversion centre. The independent Mo atom is tridentately coordinated by a nitrogen atom and two carboxylate groups of the edta4− ligand, together with the three oxo ligands, producing a distorted octahedral coordination environment. In the three-dimensional supramolecular crystal structure, the dinuclear anions, the organoammonium counter-ions and the solvent water molecules are linked by N—H⋯Ow, N—H⋯Oedta and O—H⋯O hydrogen bonds.

ammo Diisobutylammonium triphenyl(2-thiolatoacetato-κ2O,S)stannate(IV) By journals.iucr.org Published On :: 2024-08-09 Crystals of the title salt, (C8H20N)[Sn(C6H5)3(C2H2O2S)], comprise diisobutylammonium cations and mercaptoacetatotriphenylstannate(IV) anions. The bidentate binding mode of the mercaptoacetate ligand gives rise to a five-coordinated, ionic triphenyltin complex with a distorted cis-trigonal–bipyramidal geometry around the tin atom. In the crystal, charge-assisted ammonium-N—H⋯O(carboxylate) hydrogen-bonding connects two cations and two anions into a four-ion aggregate. Two positions were resolved for one of the phenyl rings with the major component having a site occupancy factor of 0.60 (3). Full Article text
ammo Isostructural behaviour in ammonium and potassium salt forms of sulfonated azo dyes By journals.iucr.org Published On :: 2024-02-15 The structures of five ammonium salt forms of monosulfonated azo dyes, derivatives of 4-(2-phenyldiazen-1-yl)benzenesulfonate, with the general formula [NH4][O3S(C6H4)NN(C6H3)RR']·XH2O [R = OH, NH2 or N(C2H4OH)2; R' = H or OH] are presented. All form simple layered structures with alternating hydrophobic (organic) and hydrophilic (cation, solvent and polar groups) layers. To assess for isostructural behaviour of the ammonium cation with M+ ions, the packing of these structures is compared with literature examples. To aid this comparison, the corresponding structures of four potassium salt forms of the monosulfonated azo dyes are also presented herein. Of the five ammonium salts it is found that three have isostructural equivalents. In two cases this equivalent is a potassium salt form and in one case it is a rubidium salt form. The isostructurality of ion packing and of unit-cell symmetry and dimensions tolerates cases where the ammonium ions form somewhat different interaction types with coformer species than do the potassium or rubidium ions. No sodium salt forms are found to be isostructural with any ammonium equivalent. However, similarities in the anion packing within a single hydrophobic layer are found for a group that consists of the ammonium and rubidium salt forms of one azo anion species and the sodium and silver salt forms of a different azo species.

The title compound crystallizes in the monoclinic space group P21/c with one tetraethylammonium cation and one nimesulide anion in the asymmetric unit. In the crystal, the ions are linked by C—H⋯N and C—H⋯O hydrogen bonds and C—H⋯π interactions. There are differences in the geometry of both the nimesulide anion and the tetraethylammonium cation in polymorphs I [Rybczyńska & Sikorski (2023). Sci. Rep. 13, 17268] and II of the title compound.
