Objective: To evaluate intra- and inter-rater reliability, standard error of the measurement (SEM), and minimal detectable change (MDC) of the angles obtained with a Postural Assessment Software (SAPO) in older people. Methods: Postural evaluation of 32 older adults was performed using Postural Assessment Software (SAPO). Two raters performed the procedure independently, and one of the raters repeated the process 7 to 10 days later. Reliability was assessed through the intraclass correlation coefficient (ICC) and paired and independent t-tests. SEM and MDC95 values were calculated, and Bland-Altman plots were generated. Results: The inter-rater analysis showed that the raters were not different in any of the angles. Most angles achieved good to excellent inter-rater reliability (ICC = 0.34 – 0.81) and intrarater reliability (ICC = 0.33 – 0.88) and were not different between days. The SEM was lower than 10º in most angles. The MDC95 ranged from 2.88º to 18.49º. Bland-Altman analysis indicated that most angles were within the limits of agreement. Overall, angles generated in lateral view had better reliability properties. Conclusion: Postural Assessment Software (SAPO) showed angles with distinct reliability properties in older adults. Angles that reached good to excellent intra- and inter-reliability and exhibited lower variability could be considered for assessing postural changes in older adults. MDC95 values could be used as a reference for indicating changes greater than the variability of the measurement.

Authors:   Konkola Copper Mines plc, Gama Musa , Chileshe Peter ,   Copperbelt University
Published: September 2022

Failure of rock, when it does occur, follows definite mechanical laws and that its probability, can, at least in some instances, be predicted sufficiently in advance of actual occurrence so as to prevent any great danger to the miner. The article chronologically describes rock failure criteria of some practical and most frequently featured strength criteria for predicting failure mechanism of rocks from rock sample or models (lab scale) to total structure or rock mass breakdown (field scale). A cross section range of criteria, from the typical and indispensable to state of the art ones, categorised under isotropic or anisotropic, stress, strain and energy related failure criteria that are predominantly derived on the basis of Coulomb, von Mises and Griffith theories of failure are reviewed. More attention and discussion has been given to most practical criteria like the Mohr-Coulomb and Hoek-Brown. Evolution of mechanisms of rock failure over time by various authors. The paper demonstrates progression of rock failure criteria, and that current theories hinge on classical ones.

Authors:   University Of Zambia, Kambole Kanyanga , Kambani Stephen ,   University Of Zambia
Published: September 2022

Zambia copper industry has been in existence for over a century. The country contains most known reserves in Africa and holding about 6 percent known copper reserves in the world. Copper production plays a big role in the performance of the economy. Copper exports account for more than 70 per cent of total exports and 12 per cent of the country GDP. However, with the rich history of mining and copper reserves, studies have shown that Zambia still exports more than 70 per cent of her raw copper blister or copper anodes. Only 5 percent of copper cathodes produced consumed locally to further produce finished products such as copper rods and cables. The study will, therefore, focus on the potential that Zambia has to add value in the copper chain downstream. Specifically, the research focused on the downstream copper production and processing potential in respect of copper blister or anodes, copper cathodes, copper rod and cables. In addition the study reviewed whether the current mineral development policies and taxation are adequate to encourage value addition downstream and also investigate local and regional market for the final copper product. The research utilised statistical data available from Central Statistical Office, Bank of Zambia, Chambers of Mines, ZCCM-IH and international Copper Study groups to establish production, export copper and import of copper rods or cables. In addition to the above, research included visits to the only two copper fabricators ZAMEFA based in Luanshya and Neelkanth Cables Limited in Ndola. Using the statistical data collected and field visits to the fabrication industry, it was established that Zambia has a potential to add more value to its downstream copper chain by producing more than 1 million copper blister or cathodes from the available smelter facilities and though enhancement of policies and taxation incentives.

Published: September 2022

This work investigated the impact of soil biochemical properties on the mechanical properties of okra (Abelmoschus esculentus) pods and groundnut (Arachis hypogaea) kernels, which are necessary for the design of production and optimization of harvesting and handling and processing operations equipment. Okra and groundnut were cultivated under seven soil treatment programs, which are: T1, the control; T2  treatment with composted manure at the of             2500 kg/ha; T3, treatment with composted manure at the rate of 3500 kg/ha; T4, treatment with fertilizer at the rate of 100 kg/ha; T5, treatment  with fertilizer at the rate of 200 kg/ha; T6, treatment with the combination of 1500 kg/ha of compost manure + 50 kg/ha of fertilizer; and T7, treatment with the combination of 2000 kg/ha of compost manure + 100 kg/ha of fertilizer. At peak maturity stage, the okra pods and groundnut kernels were harvested and subjected compression test, using a universal testing machine, at a speed of 10 mm/min. Findings of the study revealed that okra pods and groundnut kernels produced with compost manure (T2 and T3) both had higher failure force, failure energy, failure strain, rupture energy and rupture force, than the okra pods and groundnut kernels produced with NPK 15:15:15 fertilizer (T4 and T5); but a combination of the compost manure and fertilizer (T6 and T7) gave better results than the individual treatments. The groundnut kernels’ failure force ranged between 67.5 N and 131.58 N; while the okra pods’ failure force ranged between 62.77 N and 112.88 N. The results further revealed that the okra pods’ failure energy varied from 0.172 Nm to 0.324 Nm; while the groundnut kernels’ failure energy ranged from 0.044 Nm to 0.084 Nm. Similarly, the failure strain of the groundnut kernels ranged between 30.1% and 37.8%; while the failure strain of the okra pods ranged between 20.1% and 31.3%. Additionally, the groundnut kernels’ rupture force ranged between 62.89 N and 126.21 N; while the okra pod’s rupture force ranged between 59.44 N and 108.22 N. The results of this research can be used to optimize the operation of harvesting, transportation and manufacturing of processing machines; thus increasing food production.

Published: September 2022

Aim: The experiment was setup in an attempt to determine the effect of redox potentials on soil chemical properties Mat and met: A 3 x 2 x 2 factorial experiment was conducted. The experiment was laid out in Randomized Complete Block Design (RCBD) and consisted of three factors namely: Poultry manure at three levels (0 tha-1, 6 tha-1 and 8 tha-1), NPK 15-15-15 at two levels (0 kgha-1 and 200 kgha-1) and watering regimes at two levels (waterlogged and field capacity). These factors were used to induce the various redox status of the soil. The combination of these variables resulted in twelve (12) treatments which were replicated three times and repeated. The soils were incubated for about three months after which data were collected on soil chemical properties. Data collected included total N, available P, exchangeable cations and organic matter content. Data collected were subjected to analysis of variance (ANOVA) using SPSS version 17 and means compared using Tukey Honesty Significant Difference (HSD) test to verify significant differences among treatments at 5% probability level. Graphs were generated using Microsoft excel 2010 edition. Result: The results of this research showed that redox potential causes changes in the chemical properties of the soils. There was significant difference (p < 0.05) in the nitrogen content among the treatments and the highest was moderately reduced soils being 62.5% greater than the oxidized soil that recorded the lowest. There was also significant difference (p < 0.05) in the available P which was highest under oxidized soils, being 76.4% greater than the highly reduced soil that recorded the lowest. Organic matter content was highest under highly reduced soil being 42.9% greater than the oxidized soil that recorded the lowest. There were also significant differences (p<0.05) among the treatments in terms of exchangeable cations. Exchangeable cations were lowest in soil under highly reduced conditions. Conclusion: It was concluded that the redox status of a soil is a fundamental property that has the tendency of affecting other soil chemical properties.

Authors: Narang M. , Akhtar Naim , Kumar Manoj
Published: September 2022

An assessment of avian fauna of Chail Wildlife Sanctuary was carried out during a three year study between 1996-1999. The Sanctuary which is famous for its Cheer Pheasant population is highly disturbed because of the presence of 121 villages with a population of nearly 10,000. Various anthropogenic activities like cattle grazing, collection of timber, firewood, cultivation and fodder extraction etc. have contributed in degrading the Sanctuary. Nevertheless, the Sanctuary harbours a total of 138 species of birds. The list includes three endangered species included in Schedule-I of Wildlife (Protection) Act, 1972. Majority of birds (66.66%) are resident birds followed by winter migrants (15.20%) and summer migrants (13.76%). Efforts are being made by the Wildlife department to improve the habitat by carrying out plantations and developing water holes. These efforts need to be augmented by management practices like controlling forest fires and initiating eco-development programmes to reduce people’s dependence on Sanctuary resources.

Membranes and Transport Mechanisms
Authors: Mumtaz Tamseela
Published: September 2022

Cellular life depends on the movement of membrane ions. For cells to continue functioning as they go through their life cycle, there must be a tremendous amount of exchange. Cell membranes are active structures rather than merely passive barriers separating cells from their surroundings. Cell membranes are known to be selectively permeable, allowing some chemicals to pass through while preventing others from doing so. Therefore, all cellular exchange activities can have active participation from cell membranes. Through the membrane interface, elements needed for cellular existence, communication among cells, and interaction between cells and their environment are taken in. Additionally, cells have the ability to direct and influence input and export processes, as well as moderate the subsequent signal response. Effective drug transportation across cellular membranes is essential for all treatment procedures. The majority of medications used in cancer therapy require carrier proteins for their transmembrane transport, even though hydrophobic small molecules can enter the cell membrane through straightforward diffusion. As a result, many scientists concentrate on creating novel strategies to improve drug delivery and uptake into desired cells. A live cell's plasma membrane serves as its outer wall. Although it acts as a barrier, it also permits transport between the cell and its surroundings.

While the hydrophilic head groups are in contact with the surrounding water, the bilayer's hydrophobic interior, which is made up of fatty acid chains, renders the membrane impermeable to water-soluble compounds. To reduce the accessibility of hydrophobic fatty acid chains, phospholipids can spontaneously form stable bilayers in an aqueous environment due to their amphipathic nature. As lipids and proteins positioned in the plasma membrane can rotate or diffuse laterally and are distributed asymmetrically in the two leaflets, membranes are extremely dynamic structures. In addition to glycolipids, the outer leaflet of the plasma membrane mostly consists of the phospholipids phosphatidylcholine and sphingomyelin. Phosphatidylethanolamine, phosphatidylserine, and phosphatidylinositol are the three main substances that make up the inner leaflet.

Additionally, both leaflets contain cholesterol, which affects the fluidity of the membrane. Lipid rafts are particular domains abundant in sphingolipids and cholesterol. The plasma membrane's basic role as a selectively permeable wall dividing the inside from the outside of the cell is determined by the structure of the phospholipid bilayer. Membrane proteins are essential for guaranteeing the selective translocation of molecules across the membrane as well as the regulation of cellular connections. They can function as energy converters, ion channels, pumps, receptors, or enzymes. The maintenance of the osmotic pressure and cellular pH, as well as the regulation of drug uptake mechanisms, account for the regulation of fundamental cellular activities.

Published: September 2022

The article deals with the formation of informational and digital competence of high school students. First and foremost, the existing digitalization strategies for society already approved in the world and in Ukraine, including the implementation of STEM education and the Digital Agenda, are considered. On the other hand, attention is paid to the inconsistency of the level of ownership and frequency of use of digital technologies with the requirements of these initiatives. The concept of informational and digital competence is analyzed in detail. Existing publications identify key components, skills and competencies required to achieve this competence. A survey is conducted to better understand the current situation. One of the tasks is to determine the level of use of digital information in the classroom by teachers and in students’ preparation at home. The second task was to show how developing students’ informational and digital competence can be done by active introduction of existing software and hardware in the educational process in physics, in particular, a laboratory workshop. The example of laboratory work carried out in educational institutions shows how modern software can be used to analyze the movement of bodies and determine the physical characteristics of this movement. The concrete ways of performing laboratory work, analyzing its results and drawing conclusions are given. It is in the combination of existing teaching practices with modern gadgets, specialized and general programs that the basic way of forming informational and digital competence is seen. Further ways of modernization and improvement of described methods for increasing the level of information and digital competence are proposed.
Under-Pricing of IPOs: A Literature Review
Authors: Swain Suraj Kumar
Published: September 2022

This paper aims to analyse the integral factors for IPO under-pricing. There have been a number of studies and the researchers have found out various factors behind under-pricing of IPOs. We list down the factors which affect IPO under-pricing such as information asymmetry, signalling, and underwriter reputation. The very first paper on under-pricing by Rock (1986) very well explains the concept of information asymmetry as the cause of under-pricing. Allen and Faulhaber (1989) explain that the firms use under-pricing as a mechanism of signalling for future prospects. Under-pricing is a well-documented phenomenon which exists since long and is still present in the IPO market.

UMM harus memperhatikan masyarakat sekitar yang terakomodasi di Kelompok Tani Hutan (KTH) Pujon Hill dalam mengelola kawasan hutan. Lahan di sana tidak memenuhi persyaratan untuk konservasi tanah dan air karena petani di sana tidak memahami model atau tanaman konservasi. Minimnya pemahaman dan pemanfaatan pengembangan kawasan konservasi menjadi perhatian utama pengusul dan mitra. Pemilihan jenis tanaman yang memiliki kemampuan penahan erosi, seperti tanaman serai wangi, merupakan langkah pertama yang dilakukan untuk mengatasi permasalahan secara tuntas. Pembuatan alat yang berfungsi sebagai penyulingan melalui penyulingan minyak atsiri memberikan solusi untuk pengolahan tanaman menjadi minyak atsiri. Minyak sereh disuling untuk menghasilkan dua jenis minyak esensial yang berbeda. Minyak atsiri kelas A digunakan untuk penjualan langsung, sedangkan minyak atsiri kelas B digunakan untuk membuat asam karbol.

Sampah merupakan hal yang tak terpisahkan dari kehidupan. Setiap aktivitas yang terjadi akan menghasilkan sampah. Sampah ada dua jenis yaitu sampah organik dan anorganik. Sampah dapat dikelola kembali dengan menerapkan 3 hal yaitu reuse, reduce, recycle. Proses pengelolaan sampah menerapkan sistem manajemen dimulai dari  sampah terlebih dahulu dipilah menjadi sampah organik dan sampah anorganik. Pengabdian ini dilakukan dengan pengelolaan sampah organik dalam upaya membantu petani dalam manajemen modal. Pengelolaan sampah organik menjadi pupuk kompos dilakukan secara anaerob menggunakan EM4. Pengolahan sampah organik secara anaerob merupakan pengubahan sampah organik secara tertutup atau tanpa udara. Masalah yang terjadi dikalangan petani saat ini adalah kurangnya modal. Kurangnya modal tersebut sangat membebani petani karena subsidi pupuk telah dikurangi oleh pemerintah. Berkurangnya subsidi pupuk anorganik oleh pemerintah sangat memberatkan petani dalam menjalankan usahataninya. Petani dituntut untuk menambah modal dalam melakukan usahatani. Kondisi sekarang ini mendorong petani untuk mampu melakukan manajemen terhadap modal yang dimiliki. Modal memiliki banyak bentuk, salah satunya adalah modal uang yang digunakan petani dalam membeli pupuk. Penggunaan pupuk anorganik dapat diganti dengan pupuk organik atau digunakan secara bersamaan sehingga dapat mengurangi biaya dalam usahatani dengan demikian maka pengelolaan sampah organik menjadi pupuk kompos membantu petani dalam manajemen modal.
A Deep Learning-Based Technique for Diagnosing Retinal Disease by Using Optical Coherence Tomography (OCT) Images
Authors: ŞAHİN Muhammet Emin
Published: September 2022

The retina layer is the most complex and sensitive part of the eye, and disorders that affect it have a big impact on people's lives. The Optical Coherence Tomography (OCT) imaging technology can be used to diagnose diseases that are caused by pathological alterations in the retina. The importance of early diagnosis in the management of these illnesses cannot be overstated. In this article, an approach based on convolutional neural networks (CNN), a deep learning method, is presented for the detection of retinal disorders from OCT images. A new CNN architecture has been developed for disease diagnosis and classification. The proposed method has been found to have an accuracy rate of 94% in the detection of retinal disorders. The results are obtained by comparing the proposed CNN network model in a deep learning application used in classification with the MobileNet50 network model in the literature. The evaluation parameter values for models trained using the 5-fold cross validation approach for each type of disease in the retinal OCT image dataset are also submitted. The proposed method can clearly be utilized as a decision-making tool to assist clinicians in diagnosing retinal illnesses in a clinical context based on its effectiveness thus far.
LE LANGAGE ALIMENTAIRE DANS LA MUSIQUE CONGOLAISE. CAS DE BRAZZAVILLE (1991-2010)

Published: September 2022

This text analyzes the evolution of the mode of food in Brazzaville and the new language which sticks to it.It shows that to the following day events sociopolitic that this city knew, poverty led the latter to make the choice of the food of mass or street, in restaurants of fortune. This current consumption based on the frozen and flesh-colored products is declined under several names. In we let us support on onomastics and hymnology, this work explores the symbols and felt townsmen that the music congolaise, Rumba, celebrates in a normal way.However, the codes of this natural social relationship with the products for human consumption will be chamboulé by the youthful urban music, half-compartment-shifted, which exchanges the food lexicon to express the spite, the distress and the social marginalisation.Through a chopped and believed narration, it builds on the unvoiced comment and not known, imaginary in which certain names of the products pass to indicate parts of the body or bodies phallic female and pleasure that one can draw. Key words: food, Brazzaville, hymnology, language, onomastics
La pratique intertextuelle dans A Rebours de Joris-Karl Huysmans
Authors:   Université Marien Ngouabi, Congo, Nombo Augustin
Published: September 2022

A rebours by Joris-Karl Huysmans is understood on the scriptural and aesthetic level as the privileged place of discursive interactions and all forms of interculturality. Textuality only makes sense in the rapprochement of writing and reading, as well as in the deployment of pictorial and artistic discourse. Thus, we propose to study in this article this textual phenomenon from two relations of co-presence, namely, reference and quotation. Then, we will draw out its meanings, showing precisely in what way the intertextual practice would be for Joris-Karl Huysmans a quest at the same time spiritual, intellectual and artistic. Keywords: Intertextuality, Reference, quotation, des Esseintes, A rebours.
Représentation de la guerre dans la poésie nigériane
Authors:   Université Marien Ngouabi, Congo, Matongo Nkouka Anicet Odilon ,   Jean-Marie Soungoua,   Université Marien Ngouabi
Published: September 2022

This study depicts the quensequences of the war in the poetry of Nigerien authors namely Wole Soyinka, Chinua Achebe and Gabriel Okara. From the application of the sociocritical and autobiographical approaches, it appears from the texts that commitment is part of a moral and political awareness that identifies the poet in relation to a community of reprobates, no doubt, but a community fighting for a new morality. These texts are circumscribed in a context of deprivation of freedom by loneliness in prison, the slow and long disintegration that the man undergoes plunged into the abyss of prison isolation, the tortures suffered, the soiled walls, the fetid odors exhaled by the prison, the triumph of truth over the undermining of a system of repression. Prison disorients, disarticulates and fragments the personality of the prisoner who seeks to survive physical and mental attacks. It goes without saying that these texts have an autobiographical dimension. Keywords: Consequence; Death; Mental annihilation; Deprivation of freedom.
Figuration féminine et sexualité hors-normes dans l’écriture de J. Malonga
Authors:   Université Marien Ngouabi, Congo, Antsue Jean Bruno
Published: September 2022

The subject of our text is “Female figuration and extraordinary sexuality in the romantic writing of J.Malonga”. The objective of such a study is to show that the sexuality appearing in the mosaic of themes addressed by the Congolese writer is perceived as a perversion and a negativity. The objective of our study is to show that the practice of adultery in the fiction studied is not normative and becomes a site of deconstruction in social life. Indeed, the beautiful Hakoula, héroine of the novel, militates for an eroticism prohibited by the legislation. The thematic approach seems to us more interesting to approach our subject with relevance and to arrive at the results. Keywords: Norm, Sexuality, Adultery, Slave, Social life.
Métaphorisants expressifs dans l’écriture poétique de Pierre Ntsemou
Authors:   Université Marien Ngouabi, Congo, Monkala Dzaboua
Published: September 2022

This study on expressive metaphorizers in Pierre Ntsemou's poetic writing analyzes one of the aesthetic peculiarities of the nominal metaphor. It is based on the pragmatic method, which offers us six criteria among others: presupposition, expectation and implication, recipient speaker interaction. The study of occurrences from the corpus provides us with data organized in four parts. The first, the metaphorizer of the family, is perceived as an entity of social integration between continents. The second addresses paradoxical values of women in modern African society. The third, brings emotional happiness to man through his body and his functions in marriage, work and sexuality. Finally, the metaphorizer of the fog informs us about the regulatory role of the climate in love. In short, this diversity of metaphorizers enriches the expressiveness of Pierre Ntsemou's poetic writing. Keywords: Metaphors; Aesthetics; Analogy; Metaphorical and Metaphorized.
Synecdoque du corps et domaines épistémiques dans l’écriture de Mongo Beti
Authors:   Université Marien Ngouabi, Congo, Miatékéla Othon-Chrysostome
Published: September 2022

This article aims to examine the synecdoche of the body and epistemic domains in Mongo Beti, that is, it aims to show the functioning and to give a polysemy, a multifunctionality of the synecdoche in the Betian novels through the forest, social and political universe. To materialize this work, we rely on two methodological approaches: one, semiotic and the other, pragmatic. The first will help us to grasp the synecdoche of the body as a sign endowed with signifiance (Eco, 1988, p.28); the second will allow us to see it as a major theme tainted by implicit, implied (Maingeneau, 2001, p.132) and unspoken meanings. The examination of the problematic allowed us to arrive at these results: the forest is a space of hospitality and revenge; the relationship between synecdoche and the body in the traditional and urban universes; the relationship between Essola and the prison of Mundongo. Keywords: Synecdoche; Body; Forest; Social; Political
