Professionnalisation, discours et représentations des compositrices de musique contemporaine au Québec : étude de la portée
Authors: Couture Ariane
Published: May 2024

Dans les concerts réguliers organisés par les organismes de diffusion de la musique contemporaine entre 1966 et 2006 au Québec, la présence des oeuvres composées par des femmes est largement minoritaire (10 à 16 pour cent du répertoire selon les organismes) et peu intégrée (Couture 2019a). Le sujet de la progression des femmes dans le métier de composition et dans la programmation des institutions de la création artistique reste peu abordé. Il est essentiel de répertorier la portée et la nature de la littérature disponible afin d’approfondir la question et d’y apporter des pistes de solution. Une étude de la portée a été réalisée afin de dresser un inventaire structuré et analytique de la documentation disponible sur les compositrices de musique contemporaine au Québec. De cet inventaire de la littérature ressortent trois principaux constats. D’une part, malgré les grandes avancées du mouvement féministe depuis les années 1970, l’égalité de traitement entre les hommes et les femmes n’est pas atteinte en musique. D’autre part, il découle de cette inégalité un certain malaise à parler de féminisme, voire du genre féminin. Enfin, de nombreuses compositrices adoptent des pratiques musicales alternatives (électroacoustique, improvisation, installation) souvent ignorées par les bailleurs de fonds et les grands médias, ce qui les soumet à une double marginalisation en tant que femmes et travailleuses en musique.
Historiography of the Genesis of the Pentecostal Movement: Early and Recent Research Directions in English-language Literature
Authors: Tsys Aleksei Vladimirovich
Published: May 2024

The purpose of this article is to identify early and recent Pentecostal studies in the West and to highlight the main difference between them. Today there are more than 250 million Pentecostals in the world, and together with the charismatic movement there are more than 500 million. Having begun to spread in the 20th century, the movement claims to be the fastest growing religious phenomenon in human history. In attempts to interpret the phenomenon of the movement's growth, there have been several gradually emerging approaches: explaining the origin of the movement as supernaturally "coming from heaven"; searching for the origins of Pentecostalism in other Christian movements; presenting the emergence of the movement as the result of social and psychological factors such as poverty, marginalization, and the desire to escape from modern society; and the multicultural approach. The paper analyzes the works of Western historians and theologians of Pentecostalism since the second half of the 20th century. The result shows a turning point between early and late studies, namely that late studies aim to revise the history and include participants in the movement around the world, not just in North America, explore the contribution to the development of the movement of local ministers who have long remained in the shadow of Western missionaries, emphasize the diversity of ideologies and social influences that have shaped the movement. It also highlights three major contemporary areas of research: historical, characterized by studies of Pentecostalism in Asia, Africa, and Latin America; theological, focusing on the development and shaping of theoretical theology as a result of the movement's institutionalization; and religious studies, practiced primarily from the perspective of the sociology of religion.
Trends in the development of institutions and forms of artistic communication in modern St. Petersburg
Authors: Pan Liang
Published: May 2024

The subject of the study is the works of contemporary St. Petersburg artists of different generations and creative trends, as well as the forms and features of their communication with each other and with the general as well as professional public. The trends of artistic communication in the city are determined by the activities of such institutions as art and non-art museums, art galleries and exhibition centers, which are a classic form of presentation of contemporary art; alternative venues such as creative spaces and art clusters. The field of attention also includes the attraction of St. Petersburg authors to the organization of small artistic associations, mainly art groups, for example, "Unconquered", "North-7", "Parasites", etc. In addition to works of art, theoretical works and reflections by researchers of contemporary art in St. Petersburg and the spaces of its public presentation are involved. The methodological basis is the analysis of the works of St. Petersburg masters of the beginning of the XXI century in the context of the development of urban institutions of artistic communication. The research is based on theoretical works devoted to the problem of artistic communication and trends in the current art process. Comparative-interpretative and typological methods are used to compare the works of artists and forms of artistic communication. The problem of artistic communication in the field of fine art in St. Petersburg is becoming the subject of a separate study. This area of city life is currently developing quite dynamically, as new art associations, curatorial practices and alternative classical platforms for the presentation of the work of authors belonging to different generations and art movements are emerging. Traditional museums and galleries, as well as creative spaces, art clusters and other often non-core institutions, such as libraries and cafes, are involved in this process. Against this background, the features of St. Petersburg artistic communication crystallize, which is characterized by a desire to organize communities, to fuse realistic traditions and current trends, to escapism and symbolism, as well as an interest in oriental themes and stylistics.
The fundamental role of worldview in subcultures
Authors: Xu Xuchen
Published: May 2024

The subject of this work is the worldview of subculture and its complex interaction with the elements and structure of these groups. To do this, various types of subcultures are analyzed in detail in order to identify their unique ideological features and characteristics. The main purpose of the research is to find links between the worldview of subcultures and their structural elements, as well as to understand the impact of these links on socio-cultural processes. By analyzing these issues, the study seeks to expand our understanding of subcultural dynamics and their place in the modern sociocultural context. The results of this work can be useful for further research in the field of anthropology, sociology, cultural studies, as well as for the development of practical strategies for managing and supporting subcultural communities. To achieve the goals of the study, an anthropological analysis of subcultures is used, which includes an analysis of synchronous and diachronic aspects of the subcultural worldview, as well as comparative analysis. The scientific novelty of this work is manifested in a deep and comprehensive analysis of the diversity of types of worldview representation in various subcultures and their impact on a wide range of socio-cultural processes. The analysis presented in the study reveals unique aspects of the subcultural worldview and its diverse manifestations, which not only contributes to a deeper understanding of the socio-cultural dynamics of modern society, but also expands our knowledge of the mechanisms of formation and functioning of subcultural communities. The conclusions of this work are important both for academic research in the field of anthropology and sociology, and for practical applications, for example, those aimed at effective management and support of subcultural groups in modern society, including the development of policies and programs that promote inclusivity, cultural diversity and socio-cultural harmony.
The red color in Russian, French and Chinese linguistic cultures on the example of phraseology and proverbs
Authors: Zheng Wenxuan
Published: May 2024

The research conducted in this article is aimed at analyzing color symbols in Russian, French and Chinese linguistic cultures using the analysis of phraseology and proverbs. The research methodology is based on a comparative analysis of phraseological units and proverbs containing color components in these languages. In the course of the study, both common and unique features in the color symbolism of each of the linguistic cultures under consideration were identified. Through a comparative analysis of phraseology and proverbs in different languages, it was possible to better understand how color embodies cultural norms, worldview and historical contexts in each nation. This allowed us to see which aspects of color are particularly significant for each culture and what associations and symbolic meanings are associated with them. Special attention is paid to the analysis of differences and similarities in the interpretation of color in the idiomatic expressions of each language. This allows us to understand which cultural and historical factors form unique views and ideas about color in each of the linguistic cultures under consideration. The study also highlights that the interpretation of color symbols in idiomatic expressions depends on the cultural and historical contexts of each language. Idioms are a reflection of the collective consciousness and worldview of the people, and the study of color phenomena in idioms helps to better understand national identity and linguistic evolution. In addition, the study found that the red color can acquire different meanings and connotations in different languages, despite common dictionary definitions. This indicates that the use and attitude towards the color red depends on the cultural and historical characteristics of each language group. The scientific novelty of the work lies in the fact that it combines linguistic analysis with the analysis of cultural characteristics and uses the methodology of synergetic symbolism. This approach allows us to understand how the interaction of different colors creates new symbolic meanings and associations specific to each culture.
Identification of differential expressed genes and its related pathways in Hela cell line treated with urea noscapine as potent anticancer agent
Authors: Pattnaik Animesh , Naik Pradeep Kumar
Published: May 2024

Noscapinoids, synthetic derivatives of noscapine, have been identified as potential anticancer drugs in cervical cancer. This study aimed to understand the mechanism of action of noscapinoids by comparing the gene expression profiles of treated and untreated Hela cells using RNA-seq. A total of 4926 differentially expressed genes (DEGs) were identified, including BAG2, BCL2L11, HSPA4, CASP14, CASP12, CASP8, CASP10, CASP1, and CFLAR. Pathway analysis revealed 20 enriched pathways from up and downregulated DEGs, including endoproteases, cysteine-type endopeptidase activity, TNF, IL-17 signaling pathway, Mitophagy, and Shigellosis. A detailed investigation into DEGs using annotations for cellular components, molecular functions, and biological processes identified different 20 regulating activities from both up and downregulating DEGs. To determine the 50 most functional genes from each group, a protein-protein interaction network was built. These genes were then subjected to further testing by reverse transcription polymerase chain reaction. It was discovered that the downregulated genes that were the focus of the investigation were related to tumor cell invasion, migration and motility, and cell survival and proliferation. The study suggests that these DEGs could be targeted for therapeutic purposes and may serve as potential biomarkers for developing novel therapeutic approaches in cancer treatment. The research sheds light on the mechanism of action of noscapinoids and highlights their potential as a new class of anticancer drugs.

Authors: Orosco Fredmoore , Nicdao Deborah
Published: May 2024

Subunit vaccine delivery systems have emerged as groundbreaking strategies to enhance immunogenicity and efficacy, overcoming the limitations of traditional vaccine approaches. This review article delves into the vast landscape of subunit vaccine delivery systems, encompassing diverse platforms, such as polymer-based, lipid-based, micelle-based, phage-based, hydrogel-based, inorganic-based, and emulsion-based carriers. This review aimed to comprehensively explore the advancements, challenges, and potential of these delivery systems in revolutionizing vaccine development. Key findings revealed that polymer-based systems offer tunable properties for sustained release, while lipid-based and micelle-based carriers enable efficient encapsulation of hydrophobic antigens. Phage-based platforms leverage host–pathogen interactions, whereas hydrogel-based carriers provide localized delivery and adjuvant effects. Inorganic nanoparticles and emulsions offer targeted delivery and improved immune responses. These findings offer opportunities to enhance the immunogenicity of subunit vaccines, optimize antigen delivery, and tailor responses to specific diseases. This review can guide researchers, clinicians, and policymakers in harnessing the strengths of diverse delivery systems to improve vaccination strategies. By shedding light on their design, applications, and impacts, this review serves as a roadmap for the development of next-generation vaccines with the potential to transform global health-care paradigms.

Published: May 2024

The reconstruction of complete microbial metabolic pathways using ‘omics data from environmental samples remains challenging. Computational pipelines for pathway reconstruction that utilize machine learning methods to predict the presence or absence of KEGG modules in incomplete genomes are lacking. Here, we present MetaPathPredict, a software tool that incorporates machine learning models to predict the presence of complete KEGG modules within bacterial genomic datasets. Using gene annotation data and information from the KEGG module database, MetaPathPredict employs deep learning models to predict the presence of KEGG modules in a genome. MetaPathPredict can be used as a command line tool or as a Python module, and both options are designed to be run locally or on a compute cluster. Benchmarks show that MetaPathPredict makes robust predictions of KEGG module presence within highly incomplete genomes.

Maternal choline supplementation (MCS) improves cognition in Alzheimer’s disease (AD) models. However, effects of MCS on neuronal hyperexcitability in AD are unknown. We investigated effects of MCS in a well-established mouse model of AD with hyperexcitability, the Tg2576 mouse. The most common type of hyperexcitability in Tg2576 mice, and many other mouse models and AD patients, are generalized EEG spikes (interictal spikes; IIS). Hyperexcitability is also reflected by elevated expression of the transcription factor ΔFosB in the principal cells of the dentate gyrus (DG), granule cells (GCs). We also studied the hilus of the DG because hilar neurons regulate GC excitability. We found reduced expression of the neuronal marker NeuN within hilar neurons in Tg2576 mice, which other studies have shown is a sign of oxidative stress or other pathology.Tg2576 breeding pairs received a diet with a relatively low, intermediate or high concentration of choline. After weaning, all mice received the intermediate diet. In offspring of mice fed the high choline diet, IIS frequency declined, GC ΔFosB expression was reduced, and NeuN expression restored. Spatial memory improved. In contrast, offspring exposed to the relatively low choline diet had several adverse effects, such as increased mortality. The results provide new evidence that a diet high in choline in early life can improve outcomes in a mouse model of AD, and relatively low choline can have negative consequences. This is the first study showing that dietary choline can regulate hyperexcitability, hilar neurons, and spatial memory in an animal model of AD.

Published: May 2024

Some transcription factors (TFs) can form liquid–liquid phase separated (LLPS) condensates. However, the functions of these TF condensates in 3-Dimentional (3D) genome organization and gene regulation remain elusive. In response to methionine (met) starvation, budding yeast TF Met4 and a few co-activators, including Met32, induce a set of genes involved in met biosynthesis. Here, we show that the endogenous Met4 and Met32 form co-localized puncta-like structures in yeast nuclei upon met depletion. Recombinant Met4 and Met32 form mixed droplets with LLPS properties in vitro. In relation to chromatin, Met4 puncta co-localize with target genes, and at least a subset of these target genes is clustered in 3D in a Met4-dependent manner. A MET3pr-GFP reporter inserted near several native Met4-binding sites becomes co-localized with Met4 puncta and displays enhanced transcriptional activity. A Met4 variant with a partial truncation of an intrinsically disordered region (IDR) shows less puncta formation, and this mutant selectively reduces the reporter activity near Met4-binding sites to the basal level. Overall, these results support a model where Met4 and co-activators form condensates to bring multiple target genes into a vicinity with higher local TF concentrations, which facilitates a strong response to methionine depletion.

Class-B1 G-protein-coupled receptors (GPCRs) are an important family of clinically relevant drug targets that remain difficult to investigate via high-throughput screening and in animal models. Here, we engineered PAClight1P78A, a novel genetically encoded sensor based on a class-B1 GPCR (the human PAC1 receptor, hmPAC1R) endowed with high dynamic range (ΔF/F0 = 1100%), excellent ligand selectivity, and rapid activation kinetics (τON = 1.15 s). To showcase the utility of this tool for in vitro applications, we thoroughly characterized and compared its expression, brightness and performance between PAClight1P78A-transfected and stably expressing cells. Demonstrating its use in animal models, we show robust expression and fluorescence responses upon exogenous ligand application ex vivo and in vivo in mice, as well as in living zebrafish larvae. Thus, the new GPCR-based sensor can be used for a wide range of applications across the life sciences empowering both basic research and drug development efforts.
Research on building extraction from remote sensing imagery using efficient lightweight residual network
Authors: Gao Ai , Yang Guang
Published: May 2024

Automatic building extraction from very high-resolution remote sensing images is of great significance in several application domains, such as emergency information analysis and intelligent city construction. In recent years, with the development of deep learning technology, convolutional neural networks (CNNs) have made considerable progress in improving the accuracy of building extraction from remote sensing imagery. However, most existing methods require numerous parameters and large amounts of computing and storage resources. This affects their efficiency and limits their practical application. In this study, to balance the accuracy and amount of computation required for building extraction, a novel efficient lightweight residual network (ELRNet) with an encoder-decoder structure is proposed for building extraction. ELRNet consists of a series of downsampling blocks and lightweight feature extraction modules (LFEMs) for the encoder and an appropriate combination of LFEMs and upsampling blocks for the decoder. The key to the proposed ELRNet is the LFEM which has depthwise-factorised convolution incorporated in its design. In addition, the effective channel attention (ECA) added to LFEM, performs local cross-channel interactions, thereby fully extracting the relevant information between channels. The performance of ELRNet was evaluated on the public WHU Building dataset, achieving 88.24% IoU with 2.92 GFLOPs and 0.23 million parameters. The proposed ELRNet was compared with six state-of-the-art baseline networks (SegNet, U-Net, ENet, EDANet, ESFNet, and ERFNet). The results show that ELRNet offers a better tradeoff between accuracy and efficiency in the automatic extraction of buildings in very highresolution remote sensing images.

Cryptococcal Meningitis in an Apparently Immunocompetent Individual: A Case Report
Authors: Vincent Mary Diana , Govindakurup Unnikrishnan , Pillai Vanipriya Narayana , Raman Jayasree
Published: May 2024

Cryptococcus neoformans, a saprophyte, is commonly found in soil contaminated with pigeon droppings but has also been isolated from the wood of several tree species in South America and India, including the flowers and bark of eucalyptus trees. Inhalation of small, encapsulated yeasts may lead to an initial pulmonary infection. However, this is usually short-lived and frequently silent, especially in immunocompetent individuals. Immunocompromised patients are usually tested for Cryptococcus as a causative agent when presenting with features of meningitis, but when dealing with immunocompetent patients, it is seldom considered. This report presented a case of a 39-year-old male who was apparently immunocompetent, yet developed cryptococcal meningitis. He had no prior history of any chronic illness, malignancy, immunosuppressive medication, or steroid use. Routine blood investigations were within normal limits. Autoimmune workup and viral markers were negative. He had raised Intracranial Pressure (ICP), Cerebrospinal Fluid (CSF) leukocytosis, and encapsulated yeast forms consistent with cryptococcal meningitis initially demonstrated by CSF cytology examination with Papanicolaou stain and May-Grunwald-Giemsa, and further confirmed by special stains. This case highlights the role of initial cytological workup in detecting cryptococcal infection through morphological and special stain studies in an immunocompetent host.

Published: May 2024

Esta pesquisa investigou as contribuições do jogo digital Fraciomia para o ensino de operações matemáticas com números fracionários. Com base nos pressupostos da Teoria da Modificabilidade Cognitiva Estrutural, foram analisados os aspectos ergonômicos de usabilidade e pedagógicos do jogo. Os resultados da análise ergonômica revelaram que o Fraciomia, apesar de apresentar elementos relevantes para a promoção do aprendizado, apresenta um sistema de feedback essencialmente técnico, não contemplando aspectos didático-pedagógicos. Quanto à análise dos aspectos pedagógicos, os resultados sugeriram uma inter-relação entre a mediação da intencionalidade e da transcendência em contextos digitais (de jogo). Em suma, sugere-se que o jogo Fraciomia pode promover a motivação e o engajamento cognitivo dos aprendizes, contribuindo para a abstração e aplicação dos conceitos matemáticos relacionados às operações com números fracionários. Porém, por apresentar aspectos deficitários em relação à mediação da intencionalidade e da transcendência, sua utilização pode não ser apropriada na ausência de um mediador.

Authors: Vaishnavi C. , Kammar Shivanand K. , Wali Vijaya B. , Goudappa S. B. , B Prashanth.
Published: May 2024

The recent outbreak of Covid-19 pandemic resulted in global lockdown creating huge economic cost and cascading impact on different sections of society including the farming community. The farmers though directly faced socio economic impact there reported psychological distress due to anxiety, depression etc. Hence the objective of measuring the psychological impact of Covid-19 on farming community was taken up. As there were no proper measuring instruments for measuring the psychological impact especially of the farmers, a need was thus realized for constructing a specific scale. Hence, the Likerts summated rating scale procedure was followed by considering 8 dimensions. Initially 110 statements were sent to judges rating and the statements with relevancy weightage of 0.80 and above were retained. Then it was administered to farmers in non sample area for item analysis and after ‘t’ test 32 statements were retained. The Cronbach’s alpha test to measure the internal consistency of components was 0.895 and the split half method, followed for measuring the items reliability showed ‘r’ is 0.734. The scale validity was measured using face and content validity. Thus the scale has both validity and reliability. The finally developed scale consists of 32 statements under 8 different dimensions.

Forest soil is characteristically fundamental in the establishment of healthy seedlings for eventual planting out on the field. It is composed of mineral particles, organic matter, water, air, and numerous microorganisms. Two forest nursery soils at different depths were investigated at the Federal University of Agriculture Abeokuta (FUNAAB) for their mineral compositions. With the aid of a soil auger, twenty soil samples were randomly collected from different points in two sites at different depths (0-15 cm and 15-30 cm, air dried and taken to the laboratory for further analysis. Site 1 and site 2 (frequently cultivated portion for agroforestry bare-root seedlings and intermittently used portion). The obtained data were subjected to descriptive statistics. The composition of mineral elements varied with sites and depths. The level of Potassium was higher at depths 0 – 15 cm and 15 – 30 cm in site 2 than other macro-minerals (Sodium, Calcium and Magnesium) when compared between sites. The order of concentration includes K>Mg>Na>Ca. Micro-minerals were significantly higher at soil depth 0 – 15 cm in site 2 than site 1 (Fe>Zn>Mn>Cu). At soil depth 15 – 30 cm, levels of copper, zinc and manganese were significantly higher (p < 0.05) in site 1 with the following trend Cu>Fe>Zn>Mn. The study showed that forest nursery soils varied in their mineral composition along with depth in the studied sites. Site 2 had better physicochemical properties and higher level of some essential minerals needed for good performance of seedling growth at nursery stage.
Research on the Usage of PPT in Mathematics Teaching in China
Authors: Li Renhan , Yang Zezhong
Published: May 2024

With the advent of the information age, information technology has been widely used in mathematics classroom teaching. How to use PowerPoint (hereinafter referred to as PPT) effectively in mathematics teaching has received more and more attention. At present, there has been much research on it in China, however there is no complete overview and organized literature in this regard. This paper sorts out and summarizes the previous relevant studies and draws the following conclusions: (1) Previous studies on the usage of PPT in mathematics teaching mainly focus on three aspects: the value of PPT, the use of PPT and the use skills of PPT. (2) Previous research methods were single, and suggestions were mainly made through literature research, and the research conclusions were concentrated. The research on the value of PPT has not been deeply discussed and analyzed, so it lacks completeness. Most of the studies only focus on students, and there is no excessive and in-depth discussion on teachers' ability requirements. In addition, the research on the use skills of PPT has not been further implemented and verified, so the feasibility of the conclusion cannot be guaranteed. (3) There are still some gaps in the research on this topic. Most studies focus on the compulsory education stage, and there are few studies on the senior high school stage; Previous studies rarely discussed the disadvantages and shortcomings of PPT, and then did not discuss the problems that teachers should pay attention to avoid when using PPT; There are no relevant surveys and studies on students' attitudes towards PPT.
In Rodents, Methanol Extract from Ritchiea capparoides leaf has Analgesic, Anti-Inflammatory, and Antipyretic Properties
Authors: O Okorie , GC Akuodor , CE Ifediba , CC Ofor , OJ Afonne
Published: May 2024

Background: Ritchiea capparoides leaves are traditionally used in Southern Nigeria to cure fever, snake bites, aches, and malaria. Consequently, the analgesic, anti-inflammatory, and antipyretic properties of Ritchiea capparoides leaf ethanol extract were assessed in rodents in this work.
Methods: Using acetic acid and tail immersion models in mice, the analgesic effect was investigated, and xylene, egg-albumen, brewer's yeast, and dinitrophenol models were used to investigate the anti-inflammatory and antipyretic properties in mice and rats at doses of 125 mg/kg, 250 mg/kg, and 500 mg/kg of the methanol extract. The plant's leaf extract was also subjected to oral acute toxicity testing and phytochemical screening.
Results: At p<0.05 and p<0.01, the methanol leaf extract and the common medication (aspirin) considerably reduced the amount of writhes brought on by acetic acid. The reaction times of the tested agent's standard and extract groups significantly increased. The extract significantly reduced oedema in the egg-albumin-induced paw oedema model, with dose-related inhibition of p<0.05 and p<0.01, similar to aspirin. When compared to dexamethasone, Ritchiea capparoides leaf extract likewise showed a significant p<0.05 and p<0.01 effect in the xylene-induced mouse ear oedema test. Rats with pyrexia caused by dinitrophenol and Brewer's yeast both showed a statistically significant decrease in rectal temperatures. Alkaloids, saponins, tannins, flavonoids, terpenoids, steroids, and cardiac glycosides are all present in the methanol leaf extract. It was discovered that the oral acute toxicity testing were more than 5000 mg/kg.
Conclusion: The findings supported the traditional use of R. capparoides as a medicine by demonstrating the plant's possible analgesic, anti-inflammatory, and antipyretic properties at the tested concentrations of methanol leaf extract.

The Schiff base complexes of Cu (II), Cd (II), Ni (II), and Co (II) ions were synthesized utilizing Schiff base ligand. The Schiff base ligand was produced through the reaction of isoniazid with equimolar quantities of p-nitrobenzaldehyde yielding final product of N'-(4-nitrobenzylidene) isonicotinohydrazide (L). The ligand and its metal complexes were assessed by TLC, melting point determination, conductivity measurement, FTIR spectroscopy, magnetic moment analysis, and UV-Vis spectroscopy. The FTIR spectra revealed that the Schiff base ligand established coordination bonds with the metal ion by utilizing the nitrogen (N) atom of the azomethine group and the oxygen (O) atom of the carbonyl group. All synthesized compounds exhibited cytotoxicity against brine shrimp nauplii, thereby confirming their biological activity. [Ni(L)2] and [Cd(L)2] complexes displayed greater cytotoxic or anticancer efficacy. In addition, the antibacterial efficacy of both ligand and its complexes was investigated against several harmful bacteria. In comparison with the ligand (L), the antibacterial activity of the complexes of [Cu(L)2], [Cd(L)2], and [Ni(L)2] is higher, whereas that of [Co(L)2] is lower.

The experiments were conducted in Factorial randomized block design which comprised of 25 treatment combinations in which five levels of Nitrogen (0,40,80,120 and 160 kg N ha-1) and five levels of sulphur (0,25,35,45 and 55 kg S ha-1). The experiments were laid out in the two factors RCBD with three replications, The plant height, number of branches plant-1, dry matter accumulation, seed and stover yield increased with increasing N level of 160 kg N ha-1 which was at par with 120 kg N ha-1 and while significantly superior over rest of the levels of nitrogen. On the other hand, with increasing S levels plant height, increased significantly up to 55 kg S ha-1. However, the number of branches plant-1 and seed yield and shoot yield increased up to the highest dose of S (55 kg S ha-1). Considering the combined effect of N and S, the treatment combination (120 kg n ha-1 and 45 kg S ha-1) produced the maximum seed yield (21.32 q ha-1).

Dragon fruit undergoes rapid senescence during storage. This study identified the synergistic effect of Paclobutrazol and GA4+7 with different concentrations on the postharvest quality and shelf life of dragon fruits stored at ambient conditions. This study was conducted in completely randomized design. Dragon fruits were treated with different concentration of Paclobutrazol and GA4+7 and stored at ambient temperature for 13 days. Changes in fruit’s physiological loss of weight, firmness, total soluble solid, titrable acidity, and ascorbic acid were periodically recorded. The results indicated that the Paclobutrazol treated with 200mg significantly reduced the decrease of physiological loss of weight, firmness, total soluble solids, titrable acidity and ascorbic acid content. The results showed that Paclobutrazol treated with 200mg is the most effective treatment than GA4+7 for improving the postharvest quality and prolong the shelf life of dragon fruits when stored at ambient condition.

The degradation of riparian ecosystems threatens the livelihoods of communities that depend on these socio-ecological systems (SES) for their well-being. This is because; riparian ecosystems provide ecosystem services like fodder, timber, soil development, water regulation and habitat for wildlife. The riparian ecosystem in Kenya's Eastern Semi-Arid Region is one of the affected zones and information is required to understand the causes therein. This case study focussed on the Kaiti River in Makueni County to analyse the socio-economic factors leading to its riparian degradation. Data was collected between September 2018 to March 2019 using questionnaires, key informant interviews, focus group discussions and photographs. To analyse the data, SPSS version 26 interface with regression and correlation analysis was used to analyse the causes of riparian ecosystem degradation along the river. Crop farming was found to be a leading cause of degradation (R-Square =0.849, F (1, 99) =9.4495, p-value=0.0003<0.05) showing that farming accounts for 84.9% of the variations in degradation of River Kaiti riparian ecosystem. A calculated beta value implied that a unit raise in crop farming would lead to a rise in the degradation of the River Kaiti riparian ecosystem by 0.782 (p-value=0.001<0.05). The results of the study also revealed that livestock farming (R-Square =0.615, β=0.211, p-value =0.002≤0.05), lack of riparian conservation awareness (R-Square =0.573, β=-0.757, p-value= 0.002<0.05) and Commercial sand harvesting R-Square=0.659, β=0.205, p value=0.000<0.05) significantly contribute to River Kaiti riparian ecosystem degradation. Other causes significantly contributing to degradation (R-Square =0.520, β=0.212, p-value=0.001≤0.05,) were poor natural resource governance, poverty, poor infrastructure, climate change and land use changes. The study concludes that awareness creation and control of human activity in the Kaiti riparian zone would significantly reduce riparian ecosystem degradation. A multi-stakeholder approach whereby the community takes centre stage in monitoring and implementing riparian conservation measures is recommended.
