Sniffing Oriental Aromatic Scents: The Perfumery Trope in Eroticized Swahili Odes.
This Research Article was published by the Journal of the Institute of Kiswahili Studies University of Dar es Salaam Kiswahili, Vol. 84(2), 2020Swahili poets of the eighteenth and nineteenth centuries have foregrounded
adapted perfumery customs with great reverence in their works. It functions as a
vital cue to trans-Indian Ocean commonalities and as a marker of the influence
of Arabian-Manga civilisation and perfumery practices on the Swahili customs.
This paper examines the culture of scent in selected poetic works attributed to
Fumo Liyongo and Mwana Kupona Mshamu. Interestingly, the geography of
the female body parts is fused with oriental scents to excite consensual romantic
intimacy. We argue, besides historically echoing the sensuousness of oriental
perfumery in Swahili culture, that these two poets subliminally de-odorise body,
mind and soul of their readers to experience imagery of passionate intimacy.
Specifically, this article intends to focus on two prominent motifs of cross-
cultural adornment: the use of Manga attar unguent, fragrance and perfume, and
the scenting of genitalia. The article confronts these postulations concretised on
an approach based on Georges Bataille’s theory of eroticism. According to Carl
Olson, Bataille was an influential French postmodern thinker and writer who
argued that human life could best be understood by the interconnections and
workings of eroticism (1994:231-250). He mixes philosophy and anthropology
to talk about eroticism. According to Minguy, Bataille, through erotic
transgressions, saw the possibility for true human freedom and communication.
This theory, therefore, guides our arguments and counter-arguments,in the present article. It is the fulcrum upon which our discussions are premised
Mathematical modelling of the elastic behavior of structured geophysical media
Article is retractedFrom the viewpoint of modern concepts of nonlinear geophysics, the presence of the hierarchical block structure, anisotropy and heterogeneities is the defining property of the natural medium in particular of the Earth’s crust. A lot of achievements of modern self-organization theory in geophysics are based on the existence of basic structured media models. The structure plays a key role in Earth’s crust dynamic that is important for tectonic stress origin and localization as well as for next stress-relieved processes. As shown in [Starostenko et al., 2001], it is necessary to describe such a structured media at the micro-, meso- and macro-level as a sets of interacting blocks. Mathematical models created in such a way in particular numerical models of the dynamics of block-structured lithosphere al-low us to describe reliably such tectonic processes as the formation and evolution of the rift sedimentary basins [Starostenko et al., 2001], Earth’s crust compression in the subduction zones [Vengrovich, 2017], or faster tectonic processes of halo kinesis [Vengrovich, 2010]. The mechanism of local accumulation and emission of energy in the seismic waves form, which could be a way of creating a new model of earthquake source, was revealed during the investigation of rifting [Starostenko et al., 1996] and new subduction process modelling in the frame of block-structured lithosphere theory. However tectonic and seismic processes go far beyond the spatial and temporal scales. Used approaches need to be implemented in numerous models on the micro and mesolevel where it is extremely costly to calculate the dynamics of a huge number of interacting blocks. Therefore, we propose the mathematical model of the elastic behavior of the structured geophysical media allowing to obtain analytical dependencies between its elastic parameters and structure. We describe such environment in the first approximation as an elastic solid matrix with the inclusions of granules with excellent rheological properties. As usual rock formations keep irregular positions of particles different shapes and sizes in the space. These particles can be separated from the binder by fracturing. However, in this paper, we neglect nonregularity, fracturings, cap it all the granules will be considered as spherical. We combined the optical method of photo-elasticity studies [Malezhyk, 2001; Sirotin, Shaskolskaja, 1975; Sneddon, 1958; Christensen, 1979] and numerical calculations (FEM model) of stress fields dynamic in structured media using finite element analysis, overall, in such a way the proposed analytical model will be proofed. The numerical and analytical calculations of the stress fields evolution in the real earth with an internal structure are presented

East African Detective Fiction: A Basic Anatomy
This paper provides a basic survey of the current state of the Swahili detective prose. The paper highlights some thematic and formal features that distinguish the East African detective prose. To foreground the basic features of the Swahili detective prose, the generic theory has been utilized. Data was collected through library research by reading primary texts on Swahili detective while secondary data was taken from critical works such as theses and academic papers. This data was analyzed qualitatively by extracting salient features in each text. The paper too highlights some of the factors responsible for the growth and popularity of the detective genre in the East African region. The researchers found out that some of the factors for the rapid growth and popularity of this genre are their use simple plots, attractive language, and the character of the detective figure among others
Nihilism and Postproverbials in Euphrase Kezilahabi’s Poetry Anthology 'Dhifa' ('Feast')
This Research Artilce was published by the Mwanga wa Lugha Vol. 6 No. I ssue 2 ,2021This paper discusses nihilism and postproverbials as exhibited, and how occasionally
they occur
pari passu, in a postmodern Swahili anthology of
Dhifa, published in 2008 and
authored by Euphrase Kezilahabi. Nihilism is “the radical repudiation of value, meaning
and desirability” (Nietzsche Friedrich 7). It is a doctrine of skepticism that negates
among others, idealism, mythology, arbitrary morality, and sacred values while
maintaining that established institutions based on these beliefs must be destroyed. It is a
populist notion and a philosophical orientation that interrogates the meaning of life and
sees life as being hopeless and meaningless. On the other hand, postproverbials are
“radicalized proverbial utterances which subvert the logic and the pattern of
conventional proverbs, and aim to supplement an essentially traditionalist imagination
with an iconographic and modernist consciousness” (Raji-Oyelade Aderemi 49). Both
forms aim to repudiate or subvert the established mantra or ethos. Justification for our
contention of the proposed point of convergence between these strands is demonstrated
in the innovative manipulation of Swahili proverbial logics and symbolism by Kezilahabi
in his many works, and in particular,
Dhifa. We present evidence of how Kezilahabi turns
the conventional form of Swahili proverbs which normally serves as a vital medium to
prescribe and proscribe the code of conduct of the people around to postproverbials,
which are in essence, structured in a more unconventional form. Kezilahabi uses the
same path to advocate his new beliefs, and values them through postproverbials or anti-
proverbs1.We are determined to show in this paper that the use of postproverbials is a key
weapon that Kezilahabi harbours in his anti-platitudinous maneuvering to precisely drive
his agenda. Our rationale is derived from parallelism we noted between
Dhifa andThus Spoke Zarathustra (1883-1885) by Friedrich Nietzsche (2006

Technology of cleaning the flow part of gas turbine engines from contamination
Olali, M. O. Technology of cleaning the flow part of gas turbine engines from contamination = Технологія очищення проточної частини газотурбінних двигунів від забруднень / M. О. Olali, E. F. Osaisai, N. V. Olali // Зб. наук. пр. НУК. – Миколаїв : НУК, 2021. – № 1 (484). – С. 39–47.Анотація. Однією з визначальних факторів при вирішенні задачі підтримки газодинамічної стійкості компресорів газотурбінних двигунів в умовах експлуатації є підтримання технічного стану проточної частини двигунів на заданому рівні при зростанні їх наробітку. Досвід експлуатації вказує, що з усіх експлуатаційних факторів, які вливають на стан проточної частини ГТД, тільки вплив забруднення може бути з більшим чи меншим ефектом усунений за рахунок виконання промивки проточної частини в експлуатації. Вивчення різних способів очищення проточної частини показує, що найбільш важливими питаннями є обґрунтування періодичності промивки та ефективності миючих засобів, розробка способів внесення миючих засобів в проточну частину, зниження трудомісткості та витрат часу на промивку. У даній статті досліджено ефективність спеціальних миючих сумішей для очищення ГТД від забруднень, на основі узагальнення експериментальних даних. Процес мийки розглядається як результат прояву комплексу фізико-хімічних властивостей миючого препарату. Відповідно до теорії Ребіндера миючу спроможність визначено за допомогою двох факторів: поверхнева активність та поверхнева міцність, які залежать від степені дисперсності (колоїдності) миючої речовини у розчині. Досліджено та визначено миючу ефективність 6 спеціальних миючих засобів. Розроблено технологію промивки проточної частини ГТД, яка регламентує спосіб внесення миючої композиції в проточну частину ГТД, режим роботи двигуна при промивці, вибір оптимальної температури розчину та тривалості процесу промивки. Запропоновано метод для очистки проточної частини авіаційних ГТД, який не потребує препарування елементів проточної частини та складного інструментального забезпечення. При розробці технології промивки враховано не тільки технічний аспект (якість промивки), але і економічний. Визначати оптимальну тривалість промивки та її періодичність за ресурс ГТД в експлуатації на прикладі двигуна НК-8-2У. Розроблена схема установки для промивки проточної частини ГТД. Принцип роботи установки полягає в такому. Підігріта до температури 50-80оС кип’ячена вода подається від водозаправника літаків по шлангу до штуцера змішувача. Промивка проточної частини двигуна проводиться з чергуванням подачі миючого розчину та чистої води при роботі двигуна на режимі холодна прокрутка. Видалення забруднень забезпечує відновлення параметрів вентилятора і компресорів внутрішнього контура. Після промивки ступінь стиснення повітря вентилятором зросла на 1,4%, компресора – до 2%.Abstract. One of the determining factors in solving the problem of maintaining the gas-dynamic stability of compressors of gas turbine engines in operating conditions is to maintain the technical condition of the flow part of the engines at a given level with increasing operating time. Operational experience indicates that of all the operational factors that affect the state of the flow part of the gas turbine engine, only the impact of contamination can be more or less eliminated by performing flushing of the flow part in operationThe study of different methods of cleaning the flowing part shows that the most important issues are the justification of the periodicity of washing and the effectiveness of detergents, the development of ways to introduce detergents into the flowing part, reducing labor intensity and time for washing. This article investigates the effectiveness of special detergent mixtures for cleaning gas turbine engines from contaminants, based on the generalization of experimental data. The washing process is considered as a result of the manifestation of a complex of physicochemical properties of the detergent. According to Rebinder’s theory, the washing ability is determined by two factors: surface activity and surface strength, which depend on the degree of dispersion (colloidity) of the detergent in solution. The washing efficiency of 6 special detergents was investigated and determined. The technology of washing the flowing part of the gas turbine engine is developed, which regulates the method of making the detergent composition into the flowing part of the gas turbine engine, the mode of engine operation during washing, the choice of optimal solution temperature and duration of the washing process. A method for cleaning the flow part of aviation gas turbine engines is proposed, which does not require preparation of the elements of the flow part and complex tooling. When developing the washing technology, not only the technical aspect (washing quality) is taken into account, but also the economic one. Determine the optimal duration of flushing and its frequency for the life of the gas turbine engine in operation on the example of the engine NK-8-2U. The scheme of installation for washing of a flowing part of GTD is developed. The principle of operation of the installation is as follows. Boiled water heated to a temperature of 50-80oC is supplied from the aircraft tanker via a hose to the faucet fitting. Flushing of the flowing part of the engine is carried out with alternating supply of cleaning solution and clean water when the engine is running in the mode of cold scrolling. Removal of contaminants provides restoration of parameters of the fan and compressors of an internal contour. After washing, the degree of compression of the air by the fan increased by 1.4%, the compressor to 2%
Development of IoT Based Controlled Bench Power Generation System
The need for automation in the power sector is growing as technological
advancement increases. Automatic control is required for tasks like turning on
and off a power supply unit (inverter, generator, etc.). Therefore, this project
aims to develop an IoT-based controlled bench power generation system. The
study employed php scripting language, MySQL, and other web technologies
to develop an IoT-based control program to resolve the issue and create a
web application for interaction with the bench power supply used in this
project. The web application interacted with a database which was the driver
responsible for sending the Boolean values for switching or off to the physical
power supply controller. The experimental findings showed that the IoT-based
controlled bench power generation system is viable and fast in operations.
From the analysis of the results compared with the manually operated
generator, the performance is excellent, with a 75% deviation. The average
time to start the IoT system is 28.28 s, and the manually operated power
system with 261.6 s. This made it possible to develop a web application that,
depending on the Wi-Fi network's availability, allowed users to manage a
bench power supply from various locations with very little time and ease
