Recycling as creation in postmodern music
Authors: Iliescu Muhu
Published: January 2024

Recycling music from the past has a long history and takes many forms: transcription, paraphrase, parody, simple allusion, quoting, sampling, borrowing, rewriting, recomposing... These practices have changed considerably with the emergence of the postmodern paradigm. Rewriting musical works may now be seen as a way of expressing creativity relegated to distortions and comments on “found objects”. Postmodern composers thus produce infinitely recyclable and adjustable artifacts, perfectly suited to wander the planetary networks and nourish the soundscapes of the future virtual universes set to supplant, if not to the real world.
Musical skills. Communication, diagnosis and developmental problems

How can the development of imagination, and the enrichment of the spiritual and cultural level influence the effective formation of thought processes? Fields of psychology that study the relationship between thought processes and active creative imagination in light of the development of spirituality have always been relevant. Abilities are considered individual psychological characteristics that distinguish one person from another, mainly those that are related to the success of a certain activity, and giftedness is considered as a qualitatively unique combination of individual psychological abilities, based on which it is possible, success also depends on activity.
Review of Caza, Shawn M. 2021. A Handbook of Late Roman Bronze Coin Types, 324 – 395
Authors: Huston Jr Virgil H.
Published: January 2024

This book is a welcome addition to the literature of late Roman bronze coins. It is not a catalog, per se, yet can be used for coin identification quite easily. Many references focus on identifying coins based on the emperor involved. This is fine if one can read the legends or recognize the portraits, but becomes much more difficult when portraits become less specific and legends are barely readable. The focus here is on reverse types and I find that useful.

O CONTRAESPAÇO DOS POVOS INDIGENAS DA TRANSAMAZÔNICA E XINGU
Authors: Dos Santos Souza Ana Paula
Published: January 2024

Esse trabalho faz uma reflexão sobre as lutas por direitos dos povos indígenas, na região da Transamazônica e Xingu, no estado do Pará. Analisamos os registros de algumas mobilizações desses povos, ocorridas nas últimas duas décadas. Trata-se de ações realizadas pelos povos Parakanã, Assurini, Araweté, Kayapó, Xypaia, Kuruaya, Juruna e Arara da Bacia do Xingu e Transamazônica, antes, durante e depois da construção da Barragem de Belo Monte, no rio Xingu. A relação estabelecida entre o capital hegemônico e os povos do Xingu, carrega práticas colonialistas. Mas a resistência secular dos povos originários segue contrariando o espaço hegemônico ditado pelo capital. O contraespaço indígena está construindo outras racionalidades no oeste do Pará.
LOGOSPIRATARIA E MINERAÇÃO NO ESTADO DE RORAIMA: EXPLORAÇÃO ILEGAL DE MINÉRIOS NA REGIÃO DA TI YANOMAMI
Authors: Pontes Filho Raimundo Pereira , Ferreira Laíze Aires Alencar
Published: January 2024

A política indigenista colonial, no contexto brasileiro, era caracterizada pela omissão e pela invisibilidade dos indígenas por parte da metrópole lusitana. Acontece que mesmo após a transição para a modernidade, a inferioridade dos povos indígenas é determinada por um discurso de gradação e hierarquia da humanidade: a logospirataria. Isso pode ser comprovado pela proposição de leis pelas autoridades que violam dignidade dos povos indígenas e a qualidade do meio ambiente a partir do fomento da atividade mineradora. Utilizando-se de narrativas intolerantes e discursos midiáticos deliberadamente etnocêntricos, autoridades continuam culpando os indígenas Yanomami e a proteção ao meio ambiente pelo atraso econômico do Estado de Roraima. Mas até onde a proteção de direitos civis, atinentes à liberdade econômica e propriedade, pode ser utilizada como discurso perpetuador da logospirataria? Assim, o artigo objetiva trazer algumas reflexões sobre a perpetuação desse sistema excludente e possíveis alternativas para desconstrução e efetiva descolonização indígena, a partir da ponderação de princípios sob a lupa da logospirataria na Amazônia. O artigo é resultado das investigações de cunho exploratório, realizadas por meio de análise e revisão bibliográfica de artigos, livros e periódicos, teoricamente orientadas pelo referencial decolonial para que, ao final, concluir que é necessário o afastamento de discursos etnocêntricos que continuam sendo perpetuados quando da elaboração de estratégias e políticas públicas pelo próprio poder público, para que assim seja atingido o tão almejado desenvolvimento sustentável.

Published: January 2024

O objetivo do artigo é refletir sobre o cotidiano e o não-cotidiano enquanto mediações que atravessam a experiência, produzindo sentidos. Buscando interlocução na escrita literária e em teorias que abordam a vida cotidiana, o texto aproxima-se das características constituintes da cotidianidade, observando, desde a modernidade, como a fragmentação entre trabalho, lazer e vida privada acontece de formas distintas para os sujeitos, segundo suas condições materiais de vida. Para alguns, a vida cotidiana frequentemente interrompida por violências, misérias e opressões contraditoriamente resiste, enquanto é pressionada a se ajustar a uma lógica que não a comporta. Isto leva a pensar na escola, em grande parte organizada segundo os parâmetros da modernidade que forjam uma estrutura marcada pela fragmentação, homogeneização e hierarquização. Tudo isso produz um descompasso entre o que acontece a um sujeito escolar que tem suas possibilidades continuamente estorvadas, e o que a escola, regida pela cotidianidade, lhe oferece e cobra. A conclusão das reflexões conduz à observação daquilo que se produz na falta e nos interstícios da regulação, buscando o que permanece e o que se cria em meio ao que desaparece, dando a ver que a racionalidade moderna não impera soberana no mundo.

Acute otitis media (AOM) in children is one of the most common diseases. The provision of medical care in AOM is performed in accordance with the relevant clinical recommendations approved by the Ministry of Health of the Russian Federation. The article presents the risk factors concerning the AOM development in children, gives a brief description of the etiological factors and specifics about the pathogenetic mechanism. The clinical symptom patterns and diagnosis of AOM in infants are analyzed. In the treatment of AOM in children, antibiotics are prescribed more commonly than in other diseases. The article also considers the basic principles of prescribing systemic antibacterial drugs in AOM, as well as indications and benefits of using high doses of antibacterial drugs. In otalgia, the relief of ear pain is precisely the primary task. The positive role of topical otic anesthetics as first-line drugs is discussed, which helps to reduce the frequency of antibiotic use. Topical analgesic treatment in AOM is preferable because it avoids adverse events from systemic antibacterial drugs, and anesthesia may be faster, more intense and last longer versus oral analgesia. Special attention is paid to the description of the benefits, efficacy and safety of topical otic anesthetic drops with a combination of lidocaine + phenazone. The results of researches and clinical studies are presented, pathogenetically substantiating the expediency of using the lidocaine + phenazone combination in AOM and confirming its efficacy and safety.

Congenital anomalies (malformations) of the female genital tract are persistent intrauterine deviations from norm variations of size, shape, proportions, symmetry, topography and organogenesis, resulting in their function disorder. Congenital anomalies of the female genital tract account for 14% of all congenital malformations and 3–7% of gynecological disorders in children and adolescents. Currently, there are a number of unresolved issues related to the systematization and diagnosis of such anomalies. The article presents an up-to-date and carefully selected information on this topic and highlights existing difficulties that require further study. The literature review is aimed at searching for relevant classifications and modern diagnostics for congenital anomalies of the female genital tract for further personalized treatment tactics. Literature analysis has shown that the etiology and pathogenesis of congenital anomalies of the female genital tract are complex, heterogeneous and understudied. To date, there is no single generally accepted classification of congenital anomalies of the female genital tract, while the proposed article presents modern methods for diagnosing this pathology and the subtleties concerning the results interpreting for a correct diagnosis.

This article provides a literature review demonstrating modern paradigms concerning etiology, pathogenesis and management of endometrial hyperplasia processes in female patients with chronic kidney disease (CKD). Endometrial hyperplasia (EH) is a pathological process with various phenotypic cell changes and a characteristic predominance of glands over the stromal and epithelial components in the endometrium. Untimely diagnosis and treatment of EH can cause the pathology progression and the development of endometrium malignant transformation. Endometrial cancer (EC) refers to one of the most common malignant tumor forms of the female reproductive system, and EH, as a rule, is its precursor. In the gynecological morbidity structure, EH is 10 to 55%, and its incidence is steadily increasing. EH occurs as a result of excessive estrogen stimulation, when it is not compensated by the progesterone action. In addition, patients with CKD develop "immunosuppressive states" due to the use of various types of renal replacement therapy (hemodialysis, peritoneal dialysis, taking immunosuppressive drugs in patients with kidney transplant). Every year there are more and more such female patients. Over the past decade, there has been no reference in the Russian literature concerning a systematic approach to the diagnosis and treatment of EH in female patients with CKD. Considering that these were female patients of the reproductive period to a greater extent, who wanted to perform the childbearing function in the future, therefore, this problem is very relevant for the world medical community. KEYWORDS: endometrial hyperplasia, abnormal uterine bleeding, chronic kidney disease, hemodialysis, kidney transplant, peritoneal dialysis, immunosuppression.

Authors: Saddik Mohammed , Zoubeidi Ilham , Lagrini Khaoula , Achchab Hasnae
Published: January 2024

Rapid urban growth, with its construction and infrastructure needs, leads to an increased demand for sand, putting pressure on marine resources. Marine dredging is a response to this demand, but it is not without consequences. The delicate balance that Morocco must achieve lies in its ability to manage urban expansion and increasing urbanization while minimizing negative impacts on the marine ecosystem and meeting the socio-economic needs of its population. The quest for a balanced solution to this issue is crucial to ensure sustainable economic development, the preservation of valuable marine ecosystems, and the fulfillment of the housing and infrastructure needs of the Moroccan population. This intricate approach is essential for securing a sustainable future in Morocco by harmonizing economic, environmental, and social imperatives.

The primary objective of this article is to thoroughly examine the consequences of dredging activities on the Larache coastal area from both a physical and biological perspective. This comprehensive evaluation will shed light on how the marine ecosystem and the coastal environment are affected by these activities.

Furthermore, the article will not merely stop at highlighting the problems but will also put forward a range of practical measures and solutions designed to alleviate and mitigate the negative impacts that dredging may have on the Larache coastline. These measures may encompass strategies such as responsible dredging practices, habitat restoration efforts, and the implementation of environmental safeguards.

By offering a well-rounded assessment of the situation and proposing actionable steps for minimizing the repercussions of dredging, this article aims to contribute to the responsible management of coastal resources, ensuring that the Larache region can strike a balance between development and environmental preservation.
New interpretation technique for tracer well tests
Authors: Fedorov K. M. , Shevelev A. P. , Gilmanov A. Y. , Izotov A. A. , Kobyashev A. V.
Published: January 2024

Background. Tracer well tests were proposed in the last century as an approach for elaboration of detailed reservoir models. Such tests implied injecting weakly adsorbable tracers into an injection well followed by collection and analysis of samples in nearby production wells. The results were assumed to clarify well connectivity and inter-well hydraulic conductivity. However, practical application of these tests showed that the tracer penetrates into the production well much faster than predicted from estimates of the reservoir properties.

Aim. To develop a new technique for interpreting the results of tracer well tests.

Materials and methods. The process of tracer movement along a self-induced hydraulic fracture was simulated taking into account the mass transfer parameter. The developed algorithm for interpreting the results of tracer studies was tested in a deposit located in Western Siberia. The productive interval is located in the Jurassic interval of the Vasyugan Formation. An aqueous solution of thiocarbamide with a concentration of 9% was used as a tracer. Injection was carried out through injection well XX74 for 3 h. The mass of the injected tracer was 1 t. Measurements in six reacting production wells XX72, XX73, XX75, XX76, XX77, and XX78 were conducted for 75 days. During this time period, 516 samples were collected. In the first three days, 36 samples were extracted at equal time intervals; in the following two weeks, 90 samples were extracted also at equal time intervals; during the remaining days, measurements were conducted 2—3 times per week for each well. The results of the conducted studies were interpreted based on the developed methodology for all the wells.

Results. A numerical and analytical solution of the problem of tracer slug movement along the fracture was obtained. Account was taken of the mass transfer between the fluids and the layer, as well as the dissipation of the tracer slug. This solution was used as the basis for a new technique for interpreting the results of tracer well tests, which allows a greater number of fracture parameters to be determined.

Conclusion. The developed technique for determining the parameters of technogenic fractures was applied in practice. The presence of several fractures connecting injection and production wells is shown. It is established that the process of formation of such fractures in the reservoir is still ongoing.

Estimated tax revenue will increase from year to year. In addition to the number that continues to increase every year, taxes are also the largest source of state revenue. Therefore, it is important for taxpayers to deposit taxes into the state treasury in accordance with applicable regulations. This study aims to find out how to apply the final tax incentives in accordance with applicable regulations given by the government in response to Covid-19. In this study the data used are primary data and secondary data. The analytical method used is descriptive quantitative with data collection techniques in the form of interviews and documentation.

 The results obtained that the application of tax incentives decreased the comparison of income tax in 2020 before receiving tax incentives was Rp. 19,724,164 and after receiving tax incentives was Rp. 9,859,082. Meanwhile, in 2021, it can be seen from the comparison that before receiving tax incentives it was Rp. 19,840,739 and after receiving it was 10,017,530. the difference before and after incentives in year to year is quite large, namely in 2020 it is 9,865,082 and in 2021 it is 9,823,208.

 It is hoped that I-Support will be more thorough and updated with changes to existing tax regulations. I-Support is expected to be able to calculate its tax in accordance with the updated regulations. This research is expected to assist researchers in increasing academic knowledge and can provide benefits for other students in conducting research related to online sales income tax incentives.

Introduction: We study the electrochemical behaviors of sol-gel NaxNi1=3Mn1=3Co1=3O2 (NaNMC) material assembled in sodium half-cell and full-cell configuration, focusing on the cycling performance. Method: The crystalline structure and the lattice parameters of synthesized NaNMC were characterized by using X-ray diffraction (XRD). The electrochemical characterization of NaNMC sample was investigated in sodium-ion half-cell by cyclic voltammogram (CV) and galvanostatic cycling with potential limitation (GCPL). To improve the reversible capacity of sodium-ion full-cell, we suggested two presodiation methods to reduce the irreversible capacity of the hard carbon before assembling full-cell: i) the chemical method and ii) the electrochemical method. Results: In the half-cell, the specific capacity of NaNMC is about 106 mAh.g-1 and well maintained 88 mAh.g-1 after 100 cycles in a potential range of 2.0 – 4.0 V. When assembling the full-cell with a pristine hard-carbon, the cell capacity of only 30 mAh.g-1 but quickly decreased after several cycles due to large irreversible capacity of hard carbon in the initial cycle. As a result, both methods significantly increased ICE (Initial Coulombic Efficiency) of hard carbon by over 90% and enhanced the capacity of the full-cell. In particular, the reversible capacities of full-cell based on presodiated hard carbon (HC) were twice higher than those with pristine HC (75 mAh.g-1 and 65 mAh.g-1, respectively, for the electrochemical method and the chemical method). Conclusion: These encouraging results indicate an accessible solution to overcome the low ICEs of hard carbons, leading to improving the sodium-ion full-cell's reversible capacity.
Effect of waves, tides and storm parameters on water level rise through numerical simulation
Authors:   Naval Academy, Ministry of National Defence, Pham Tri Thuc
Published: January 2024

In this study, the foot water is calculated by the factors of collecting parameters and tides, calculated waves are analyzed by the tidal integrated numerical model, Toring sea and storm surge (SuWAT - Surge, Wave and Tide). The SuWAT model has been applied to calculate storm surge in a number of storms that have made landfall on the northern coast (such as storms Franki-96, Washi-05, Xangxane-06, Kalmeagy-14) with some calculation options different. The results show that the influence of the tide on the rising water level is negligible in places with low tidal amplitude and with storm landing at high tide, the water will be lower than when the storm makes landfall at low tide; The water surge due to atmospheric pressure is only significant in the offshore area when the storm intensity is still strong. Meanwhile, in the area, shoreline rise due to wind stress and wave stress accounted for the majority of the total water level rise during storms. With storm parameters, the storm surge at Hon Dau station reached the maximum value with the case where the storm's movement speed was 1 hour slower than the actual one. The magnitude of the water decreased as the pressure in the storm increased, but the magnitude increased at three different stations. Water level rise at 3 stations Cua Ong, Hon Dau, and Hon Ngu increased with wind speed, however, Hon Ngu station had a higher rate of increase. The magnitude at Cua Ong station increases slowly. The water surge at Cua Ong station is dominated by wind speed more than at Hon Ngu station. The research results will be very useful in warning and forecasting storm surge in the area.

Therefore, the development of artificial bone graft is essential for biomedical applications. In this study, the feasibility of bioactive cockle shell Aragonite/ Gypsum composite as bone cement for bone repair has been demonstrated. It is meaningful to use the by-products from the food industry, such as cockle shells for the preparation of valuable biomedical materials. Method: Bioactive cockle shell Aragonite/Gypsum composite as bone cement was prepared using cockle shell and Calcium Sulfate Hemihydrate (CaSO4. 0.5H2O) powder mixtures with different weight ratios. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Scanning electron microscope (SEM) were used to characterize phase composition and structure. Mechanical strength was evaluated in terms of Diametral Tensile Strength (DTS), and in vitro bioactivity was investigated using Simulated Body Fluid (SBF) solution. Results: The results indicated that cockleshell Aragonite/Gypsum composite as bone cement is bioactive, and its properties depend on weight mixing ratios. In conclusion, cockle shell Aragonite/Gypsum composite is ideal for reconstructing bone defects due to its bioactivity and abundant supply.

High precision and product surface finish quality are the main characteristics of these precision machine tools. Machining with different tool paths at different feed rates is applied to increase productivity. Today, machine tools using high-speed machining methods have been developed to shorten machining times and increase production capacity. However, the vibration of high-speed machine tools is the main cause of product quality reduction. The effect of the machining speed on the vibration diagnostic process of the machine is to choose the appropriate machining mode. This paper describes the vibration analysis methods of machine tools based on simulated results to determine the natural frequencies of vibration and dynamic modeling of the ball-screw feed drive system. Analysis of structural simulation results shows that the higher the rigidity of the machine, the lower the vibration amplitude, and the greater the ability to absorb and suppress vibrations for the machine tool without using dampers. Meanwhile, the combination of the measurement analysis and dynamics modeling on machine tools is an effective method for optimizing speed and controlling machining vibrations. First, the finite element model (FEM) is applied to determine the stiffness analysis and the natural vibration frequency of the machine tool. The simulation results are analyzed and compared with experimental measurement results. The vibration frequency of the ball-screw drive system during machining at different feed rates is also modeled and verified by the measurement results. Finally, the results from the proposed methods are used to predict the vibration frequency of the system, especially the ball-screw through the feed drive or rotational speed. In addition, the purpose of the proposed method is to prevent resonance by way of the forced frequency away from the natural frequency in high-speed machining. This paper proposes a survey method that can be applied for high-speed machine tools with different structures to choose an appropriate feed rate in machining.

Nowadays, rechargeable Li-ion batteries represent almost all human activities. Therefore, the requirements of battery optimization for power density, energy density, and cycle life are becoming necessary. Based on negative commercial graphite, graphite‒silicon composite (G‒Si) material has become a potential anode for Li-ion batteries due to its high specific capacity and energy density. This paper presented the investigation the electrochemical performance of the G‒Si composite in the carbonate based solvents which consisted of 1 M LiPF6 dissolving in the solvent of EC‒DMC 1:1 (v/v), EC‒DEC 1:1 (v/v), or EC‒EMC 1:1 (v/v). The results showed that the G‒Si composite delivered a high capacity of 616.0 mAh/g with the highest capacity retention of 64.2% (50 cycles) at the current density of 40 mA/g in the EC‒EMC 1:1 (v/v) solvent. However, when the current density was doubled (80 mA/g), the capacity of G‒Si in EC‒DEC 1:1 (v/v) rapidly decreased, while the capacity of the EC‒EMC 1:1 (v/v) maintained the highest. The EIS showed that the Rsf and Rct values in the EC‒DEC 1:1 (v/v) based electrolyte gradually increased with cycles which appropriated to the GCPL results. Besides, the intercalation diffusion mechanism of Li+ into the G‒Si composite confirmed that this process could be divided into two main regions where the diffusion coefficients were the minimum and related to the plateaus in the discharge curves of G‒Si material.

Nonthaburi, a suburban province adjacent to the Bangkok Metropolis, has experienced a reduction in green spaces due to urban expansion. This study quantified Nonthaburi’s green space through visual interpretation of land use and land cover (LULC) using THEOS and Sentinel-2. Areas of green space were extracted using remote sensing indices and pixel-based classification based on THEOS. The extracted green area was then integrated with the existing LULC patterns to align with the green space characteristic established by Thailand’s Office of Natural Resource and Environmental Policy and Planning. This includes public services, functional utility, median strips, community economics, fallow, and natural green space. The analysis of green space management and planning utilized the Urban Green Space Index (UGSI), Per Capita Green Space (PCGS), and accessibility to public green space. The results revealed that Nonthaburi comprises a green space area of 465.29 km2 or 73.06%, exhibiting a higher prevalence within its western region while displaying a relatively lower extent in the urban zone adjacent to the Bangkok Metropolis. The per capita green space is 367.71 m2 but decreases to 255.82 m2 when accounting for the latent population, meaning it still meets the World Health Organization (WHO) criteria. Currently, only six parks (single and clusters) meet the criteria for public green space. Additionally, both fallow and median strip green spaces (at road interchanges) need to be considered for their potential use in new public service. Furthermore, very high-resolution imagery from unmanned aerial vehicles (UAVs) should be used for green space planning by the organization.

Authors: Mondal Subhasis , Datta Debasis
Published: January 2024

Nitrile-butadiene rubber, commonly known as nitrile rubber, is one of the most usable synthetic rubbers that exhibits excellent heat and oil resistance. Nitrile rubber has a variety of applications, such as manufacturing of gaskets, footwear, sponges, and so on, where natural rubbers cannot be used. This paper presents a unique method of monitoring the vulcanization process in real time for nitrile rubber mixed with varied ash content (china clay and whiting) and an MBTS (benzothiazyldisulfide) accelerator using ultrasonic nondestructive evaluation (NDE). An experimental setup includes a fully automated system for acquiring ultrasonic data that has been developed in-house. It has been found that ultrasonic velocity can distinguish between china clay and whiting content in rubber, along with monitoring the curing rate and completion of curing of rubber. The cross-link density of every test sample is calculated using the equilibrium swelling method, followed by its evaluation using ultrasonic responses.

Published: January 2024

A major portion of the world’s population relies on rice as a staple diet, hence rice is essential to maintaining food security worldwide. Unfortunately, rice crops are susceptible to a number of illnesses that, if detected and treated promptly, can result in significant output losses. Expert visual inspection is a time-consuming and arbitrary part of the conventional procedures for diagnosing diseases in rice. An effective method for automated illness diagnosis in agriculture has evolved in recent years: deep learning, a branch of artificial intelligence. The objective of this research is to compare AlexNet, DCNN, MobileNet, GoogleNet, VGG16, ResNet50 and Xception, these are various deep learning models in order to choose the one that would produce the highest levels of accuracy, precision recall, specificity, and F1-score for detecting rice diseases. In this study we train the model for nine different types of rice diseases named as Rice Blast (Pyricularia oryzae), Rice Sheath Blight (Rhizoctonia Solani), Bacterial Leaf Blight (Xanthomonas oryzae pv. oryzae), Tungro Disease, Rice Grassy Stunt Virus (RGSV), Rice Yellow Mottle Virus (RYMV), Bakanae Disease (Fusarium moniliforme), Brown Spot (Cochliobolus miyabeanus) and Rice Tungro Bacilliform Virus (RTBV) with 30,000 images. For this we used the secondary dataset for analyzing the performance of models. We trained the model for both normalized and non-normalized dataset. After comparing the various models we get the better result from ResNet50 model with accuracy of 97.50%.

Rainfall defines livelihood patterns among agrarian communities of the climate-change vulnerable semi-arid Sub-Saharan Africa. However, it remains inadequately studied, resulting in ineffective water management policies and weak agricultural growth in the region. Monthly rainfall data collected between 1987 and 2018 at four stations along a 1200 km climatic gradient in northern Namibia were analysed for annual, seasonal and monthly trends and variability. Descriptive measures and the Mann-Kendall test were used for rainfall characterisation and trend detection, respectively. Results showed an annually increasing rainfall trend, but with a downward trend in the dry season decreasing by -0.14 mm year–1 and an upward trend in the rainy season increasing by 7.74 mm year–1 across the study area. The rainy-season mean monthly rainfall showed predominantly increasing trends, while the dry-season ones exhibited insignificant decreasing trends. The study detected a decreasing rainfall gradient from the northeast towards the northwest with a range of 156.8 mm and concomitant increasing spatial-temporal variability. The upward rainfall trend has implications for rainy season floods, whereas the downward trend suggests dry season drought intensification in the area. These results could be useful for rainwater management planning in the study area and other dryland regions.
Agronomic and morphological diversity of Bambara groundnut (Vigna subterranea (L.) Verdc.) accessions in North-Central Namibia

Published: January 2024

Bambara groundnut (Vigna subterranea (L) Verdc.) is an orphan, underutilised and less exploited crop in Africa and beyond, yet it is an essential traditional crop for subsistence farmers in sub-Saharan Africa. Currently, in Namibia, neither a pre-breeding nor a breeding programme exists for Bambara groundnut. Twenty-five Bambara groundnut accessions acquired locally and outside Namibia were characterised for descriptor state, including possible character diversity on the quantitative descriptors. Square lattice design with three replications was used. Data were analysed using analysis of variance (ANOVA), Pearson correlation moment, Principal Component Analysis (PCA), and cluster analysis. ANOVA indicated significant differences (P < 0.05) among accessions for most of the characters measured, and highly significant differences (P < 0.01) for the number of pods per plant, pod yield, seed yield, plant height, and dry biomass. The dendrogram sub-criterion indicated three clusters, confirming the results of the PCA, which grouped accessions with common descriptors in the same quadrants. PCA biplot showed that the first two components explained 59.55% of the variation. Overall results suggest that the Bambara groundnut accessions evaluated in this study showed high variability, thus can be used as a source of pre-breeding materials to initiate a national breeding programme.

Veterinary medicines are an indispensable tool for animal disease control and prevention. Misuse, improper handling and storage can render veterinary medicines less effective. A cross-sectional study was carried out on 60 cattle farmers in the Kabbe South Constituency of the Zambezi region in Namibia. The objective of the study was to find out the usage and storage practices of veterinary medicines. Selected farmers were interviewed using semi-structured questionnaires. Results of the study showed that the majority of respondents were males (78.3%, n=47) with at least primary school level education. Overall, farmers acquired and used 13 different types of veterinary medicines from licensed shops and pharmacies (73.4%, n=44), the state veterinary office (23.3%, n=14) and from unregistered veterinary medicine agents (3.3%, n=2). The medicines comprised of antibiotics (n=4); vaccines (n=3); combination of ectoparasiticide and anthelmintic (n=2), ectoparasiticide (n=1), anthelmintic (n=1) and vitamins (n=2). Although 36.7% (n=22) of the farmers owned or had access to a refrigerator, the majority (86.7%, n=52) did not maintain the cold chain. Most of the respondents (93.3%, n=56) self-diagnosed animal diseases and decided on the treatment without consulting a veterinarian. Oxytetracycline was the most commonly used veterinary medicine and was used at less than the recommended dose of 1ml/10kg by most respondents (83.3%, n=50). Although farmers sourced veterinary medicines from licensed retailers, the break in the cold chain and the under dosing of medicines may impair effectiveness. Self-diagnosis and treatment of animal diseases promotes misuse and the development of antibiotic resistant bacteria in cattle which may render antibiotics on the market less effective. The training of all stakeholders along the veterinary medicine value chain in the region is recommended.
