Технология приготовления оксидно-никелевых катализаторов путем пропитки инертных носителей накладывает ряд определенных требований к физико-химическим свойствам никельсодержащих соединений, используемых для приготовления жидкой фазы. В растворах пропитки должны отсутствовать компоненты, которые являются каталитическими ядами, отработанные смеси содержат минимальное количество токсичных соединений, а продукты их термического разложения - экологически вредных газообразных веществ. В настоящей работе представлены результаты ИК-спектрометрического изучения влияния природы порошков оксида, гидроксида и основного карбоната никеля (II) в диапазоне 4000-450 см-1 на растворимость в аммиачно-карбонатном водном растворе. Растворимость твердой фазы определяется строением кристаллических решеток NiO, Ni(OH)2 и Ni2(OH)2CO3. Процесс растворения никельсодержащих соединений в аммиачно-карбонатном растворе происходит в результате образования в жидкой фазе смешанных аква-аммиакатных комплексов никеля (II), состав которых изменяется от времени. Спектрофотометрические данные никельсодержащих аква-аммиачных растворов показывают два максимума интенсивности светопоглощения в интервалах длин волн 365-375 нм и 600-620 нм. С увеличением времени растворения значение максимальной оптической плотности повышается, в результате уменьшения содержания доли аква-формы и увеличения доли аммино-формы в аква-аммиакатных комплексе никеля (II).
The technology of preparation of nickel-oxide catalysts by impregnation of inert carriers imposes a number of specific requirements for the physicochemical properties of nickel-containing compounds used for the preparation of the liquid phase. The impregnation solutions should be free of components that are catalytic poisons, the waste mixtures contain a minimum amount of toxic compounds, and the products of their thermal decomposition - environmentally harmful gaseous substances. The present paper presents the results of an IR spectrometric study of the effect of the nature of nickel (II) oxide, hydroxide and basic carbonate powders in the range of 4000-450 cm-1 on solubility in an ammonia-carbonate aqueous solution. The solubility of the solid phase is determined by the structure of the crystal lattices NiO, Ni(OH)2 and Ni2(OH)2CO3. The process of dissolution of nickel-containing compounds in an ammonia-carbonate solution occurs as a result of the formation of mixed aqua-ammonia nickel (II) complexes in the liquid phase, the composition of which varies with time. Spectrophotometric data of nickel-containing aqua-ammonia solutions show two maxima of light absorption intensity in the wavelength ranges of 365-375 nm and 600-620 nm. With an increase in the dissolution time, the value of the maximum optical density increases, as a result of a decrease in the content of the aqua-form fraction and an increase in the proportion of the ammino-form in the aqua-ammonia nickel (II) complex.

Caring for patients near the end-of-life at Mayo Clinic: a narrative
Authors: Ingram Cory 
Published: June 2022

I’m a palliative care and hospice doctor focusing my clinical care on families near the end of life. It has been a great privilege to be welcomed to the bedside of so many seriously ill and dying patients to care for them and their families. Pursuing geriatrics and palliative care were not always met with welcome sentiments from my peers. “You’re going to take care of sick and dying patients.” “It is so depressing.” My experience is that geriatrics and palliative care are a little like peeking through the old skeletal keyhole into a living room. You have to get up real close to peek inside and if you dare to go through and enter in, a whole new world opens. It is often a sacred space. A space for a team of professionals caring together.

Published: June 2022

The history of art in the present day is any activity or man-made means of expressing thoughts, feelings, in a visual form, for aesthetics or communication purposes. From time to time the arts were classified into various forms. In the formation of culture from prehistoric times to the present, palm leaves have a special significance in the contribution of art, which is still a living art in Odisha. Palm leaf was extensively used for writing and illustration. Odisha is considered to be the richest state in terms of pothis. The role of Odisha State Museum in this is unique, which is making the visitors well acquainted with the palm leaf art of Odisha. A main feature is the writing work with illustrations on palm leaves. Even in the narrow gap of the palm leaf, artistic combination is formed on seeing it, in which sweet pothis have been created by establishing harmony in the art elements.
Generally, picture composition means to organize various visual elements in an artistic way or to give them a beautiful arrangement. On the subject of combination, Indian and Western scholars have created many texts by explaining many theories, so on the basis of these principles, we will present a combinational interpretation of the palm leaf paintings of Gitagovind Pothi. In these palm leaf paintings, mainly elements like line, color, tone, shape etc. have been expressed and created. Like the elements of art, the principles of combination have their own importance, in the absence of which the combination cannot be successful. The 8 main principles of composition are repetition, harmony, opposition, proportion, balance, effectiveness, rhythm, and unity.
