The hallmark of democracy is regular elections. The education of voters before elections must be effective and efficient. This study on the knowledge gap in elections identifies potential ineffective voter education strategies that result in the success of vote-buying, a hotly debated and viral topic in today's conversation on the conduct of elections in Nigeria. The research method employed for the study was survey. Copies of the questionnaire were utilized to collect information, which was then analyzed using basic descriptive statistical techniques. The study, which is based on theories of the State and Clientelism, aims to ascertain the degree to which INEC, NGOs, and other Government agencies educated the electorates before the 2023 elections as well as the level, if any, of vote-buying in the Delta state governorship elections. The results demonstrate that there is a lack of effective and efficient voters' education, and this has a detrimental influence on citizens' trust and confidence in Nigeria's electoral system, resulting in a variety of electoral manipulations. Before elections, the report suggested voter education to inform the people.

Los alimentos orgánicos se producen mediante prácticas que promueven la fertilidad del suelo y la diversidad biológica, y excluyen todos los productos químicos que se usan en la agricultura convencional. Se ha observado que, en ciertas regiones, este tipo de producción no presenta serios inconvenientes, ya que este sistema protege los cultivos de altos niveles de plagas y enfermedades. La demanda de alimentos orgánicos se ha estado incrementando desde hace dos décadas, por lo que producir a baja escala, en pequeñas superficies, y en forma aislada, no satisface los requerimientos del mercado. Esta demanda se ha convertido en una oportunidad de desarrollo muy importante en muchos países, pero al mismo tiempo tiene el inconveniente de que, al tratar de ampliar las superficies, obtener altos rendimientos, y mejorar la calidad, se pueden afectar algunos principios básicos de la agricultura orgánica. En superficies mayores aumentan las poblaciones de plagas y enfermedades, por lo que es necesario implementar algunas actividades que ayuden al sistema a reducir dichas poblaciones nocivas. En este tipo de agricultura se permite el control biológico, cultural, mecánico y físico, entre otros, aunque su utilización se ve limitada por los mismos estándares y reglamentos señalados por las agencias certificadoras. Es muy importante para los productores tener un manejo óptimo de plagas, a partir de las estrategias recomendadas actualmente, pero que estén consideradas dentro del ambiente regulatorio del movimiento orgánico. En este trabajo se presentan algunas de las alternativas más adecuadas para implementar un programa de manejo, a partir de la regulación actual para lograr y mantener la certificación como productor orgánico, y no ponerla en riesgo.
Movimiento, Cuerpo y Espacio. Sobre la potencia que guarda la detención

Published: January 2024

We propose a bibliographic review that allows an approach to three concepts: movement, body and space, in order to suggest, in form of enquiries, some relationships that can be traced between them. We dare to question the denial of each one of them as a possible inauguration of the other two. The pause in movement as a gesture that reveals the body and space. The absence of the body as an agent that gives rise to movement and space. The potential charge of a space that has not yet been determined, allowing the movement of bodies to be performed with creative freedom.
Planteamos una revisión bibliográfica que permite un acercamiento a tres conceptos: movimiento, cuerpo y espacio, con el fin de proponer, en forma de inquietudes, relaciones que pueden trazarse entre ellos. Nos atrevemos a cuestionar la negación de cada uno como posible inauguración de los otros dos. La detención del movimiento como gesto que desvela el cuerpo y el espacio. La ausencia del cuerpo como agente que hace surgir el movimiento y el espacio. La carga potencial de un espacio que aún no se determina como aquello que permite el movimiento de los cuerpos con la libertad de crear.

Authors: Obisesan Omodara E. 
Published: January 2024

This study trained six machine learning models to predict meteorological variables at a tropical location. The models used are: Multiple linear regression, Decision tree, Random forest, Support vector machine, Extreme gradient boosting and Multilayer perceptron. This was with the aim of determining the best machine learning model for weather forecasting in a tropical location. The meteorological variables that were predicted are: Temperature, Solar radiation, Relative humidity and Wind speed. To identify the efficiency and to quantify the predictive capacity of each models, evaluation metrics such as coefficient of determination (R2), mean absolute error (MAE), mean absolute percentage error (MAPE) and mean square error (RMSE) were employed. The best performed model for temperature is the Random Forest which has R2 of 0.93, MAE of 0.78 0C, MAPE of 2.84 % and RMSE of 1.13 0C. Also, the best performed model for solar radiation is the Random Forest having an R2 value of 0.72, MAE of 85.34 W/m2 and RMSE of 19008.45 W/m2. For relative humidity, Random Forest also has the best performance. From the evaluation metrics, it has R2 of 0.92, MAE of 3.41 %, MAPE of 0.75 % and RMSE of 24.71 %. The best performed technique for predicting the wind speed was also the Random Forest having an R2 value of 0.79, MAE of 0.16 m/s and RMSE of 0.044 m/s. The study concluded that the best machine learning model for predicting meteorological variables in a tropical location is the Random Forest.

Published: January 2024

Aim: The traditional harvesting of cauliflower has been done by hand using labor-intensive, expensive, and time-consuming techniques that frequently lead to significant yield losses because immature curds are harvested without selection. A rising number of people are interested in creating selective cauliflower harvesters that can precisely detect and gather healthy, mature heads while reducing damage, waste, and labor-intensive operations in response to these difficulties. The purpose of this research article is to present a thorough analysis of the ownership and operating costs related to this kind of selective harvesting technology.
Methodology: Through accurate cost insights, farmers can make well-informed decisions on the purchase of new machinery, the maintenance, and upkeep of current equipment, or the investigation of alternative approaches to improve farm productivity and financial results. The economic assessment was conducted through the computation of operating costs utilizing the straight-line method, coupled with breakeven point analysis and determination of the payback period.
Results: The developed selective harvester's ownership and running costs are calculated to be 58.41 and 75.5 rupees per hour, respectively. The selective harvester has several advantages over typical manual harvesting techniques, as demonstrated by a comparative analysis. In particular, the selective harvester shows a remarkable 24.6% cost reduction in addition to saving an astounding 60.6% of the necessary time.
Conclusion: These results highlight the efficiency and financial gains that come with using selective cauliflower harvesting technologies. This analysis is further utilized by farmers for decision-making.
Transformation of arsenic(V) by the fungus Fusarium oxysporum melonis isolated from the alga Fucus gardneri
Authors: Granchinho Sophia C. R. , Franz Catherine M. , Polishchuk Elena , Cullen William R. , Reimer Kenneth J. 
Published: November 2002

AbstractA fungus isolated from the macroalga Fucus gardneri was identified by using 28S rDNA sequence analysis, 99% similarity match, as Fusarium oxysporum meloni. The fungus was exposed to arsenic(V) (500 ppb) in artificial seawater to investigate the possibility that the fungus is the source of the metabolic activity that results in the presence of arsenosugars in the macroalga. High‐performance liquid chromatography coupled with inductively coupled plasma mass spectrometry was used to identify the arsenic species in the fungus, and in the growth medium. The fungus was able to accumulate arsenic(V) and an increase in arsenite and dimethylarsinate was also observed. Some reduction of arsenate led to a small increase of arsenite in the growth medium. The fungus does not seem to be involved with the accumulation of arsenosugars by the Fucus. Copyright © 2002 John Wiley & Sons, Ltd.

AbstractThe concentrations of total arsenic and arsenic species in the complete organism of the crayfish Procambarus clarkii and its various parts (hepatopancreas, tail, and remaining parts) were analyzed in order to discover the distribution of arsenic and its species. With this information it will be possible to establish where the chemical forms of this metalloid tend to accumulate and what risks may derive from the contents and species present in the edible parts of this crustacean. The total arsenic content in the complete organism and in the various parts analyzed ranged from 2.5 to 12 µg g−1 dry mass (DM), with inorganic arsenic representing 18 to 34% of total arsenic. The arsenical composition varied according to the part of the crayfish considered. The hepatopancreas had the highest levels of total arsenic (9.2–12 µg g−1 DM) and inorganic arsenic (2.7–3.2 µg g−1 DM). The tail (edible part) had the lowest levels of both total arsenic (2.5–2.6 µg g−1 DM) and inorganic arsenic (0.46–0.64 µg g−1 DM). The predominant organoarsenical species were the dimethylarsinoylribosides: glycerol riboside in the hepatopancreas, sulfate riboside in the tail, and sulfonate and phosphate ribosides in the remaining parts.

Review: Biological methylation of less‐studied elements
Authors: Thayer John S. 
Published: November 2002

AbstractBiological methylation is an enzymatic process in which a methyl group is transferred from one atom to another. For elements having atomic number greater than 11, biological methylation has been most extensively studied for three elements: arsenic, mercury and sulfur. However, many other elements also undergo biological methylation but have received less attention. Recent work on these less‐studied elements and new applications of biological methylation to environmental remediation, along with a description of these reactions in terms of bonding models, is the focus of this review.

Review: Reactive selenium metabolites as targets of toxic metals/metalloids in mammals: a molecular toxicological perspective
Authors: Gailer J. 
Published: November 2002

AbstractHuman activities have been contaminating the environment with toxic heavy metal and metalloid compounds. Since the toxicity of one metal or metalloid can be dramatically modulated by the simultaneous ingestion of another, studies addressing the molecular basis of chemical interactions between toxic and essential elements are increasingly important. The intravenous injection of rabbits with selenite and arsenite or with selenite and mercuric mercury resulted in the in vivo formation of the seleno‐bis (S‐glutathionyl) arsinium ion, [(GS)2AsSe]−, or a glutathione‐coated mercuric selenide, (GS)5(HgSe)core, in blood. The formation of these species (and the formation of a cadmium–selenium species in blood after the exposure of rats to selenite and cadmium) critically involves reactive selenite metabolites, such as GS–Se− and/or HSe−, which indicates that these physiologically important metabolites are molecular targets of ingested toxic metals and metalloids. The fate and stability of [(GS)2AsSe]− and (GS)5(HgSe)core in vivo imply that the chronic exposure of mammals to inorganic arsenic and mercury will cumulatively affect the bioavailability of selenium, which could lead to selenium deficiency. Since selenium deficiency is significantly associated with the etiology of cancer in humans, the GSH‐driven in vivo formation of selenium‐containing metal and metalloid species provides a likely molecular mechanism for the chronic toxicity of environmentally persistent inorganic arsenic, mercury and cadmium.

Published: November 2002

AbstractA series of new N‐benzoyl‐N‐tert‐butyl‐N′‐(β‐triphenylgermyl)propionylhydrazines were synthesized by the condensation reaction of β‐triphenylgermyl propanoic acid with N‐benzoyl‐N‐tert‐butylhydrazines in good yields by using N,N′‐dicyclohexylcorbodiimide as dehydrating agent. These title compounds were evaluated for molting hormone mimicking activity. The results of bioassay showed that the compounds exhibit moderate larvicidal activity, and toxicity assays indicated that the title compounds can induce a premature, abnormal and lethal larval molt. We found that the title compounds possess potential anticancer activities in vitro. Copyright © 2002 John Wiley & Sons, Ltd.
Hypervalent selenium compounds containing N → Se intramolecular interactions: synthesis, characterization and X‐ray structures of [2‐(Me2NCH2)C6H4]SeS(S)PR2 (R = Ph, OiPr)

Published: November 2002

Abstract[2‐(Me2NCH2)C6H4]SeS(S)PR2 [R = Ph (1), OiPr (2)] were prepared by reacting [2‐(Me2NCH2)C6H4]2Se2 with the appropriate disulfanes, [R2P(S)S]2. The compounds were characterized by multinuclear magnetic resonance (1H, 13C, 31P). The molecular structures of 1 and 2 were determined by single‐crystal X‐ray diffraction. Both compounds are monomeric and the nitrogen atom of the pendent CH2NMe2 arm is strongly coordinated to the selenium atom. The organophosphorus ligands are monodentate, thus resulting in a T‐shaped coordination geometry around selenium. Copyright © 2002 John Wiley & Sons, Ltd.
Spatially explicit trophic modelling of a harvested benthic ecosystem in Tongoy Bay (central northern Chile)
Authors: Ortiz Marco , Wolff Matthias 
Published: November 2002

Abstract
A dynamical and spatial simulation model of a harvested benthic ecosystem of central northern Chile (Tongoy Bay) was constructed using the ECOSPACE software package.
In this system the red alga (Chondrocanthus chamissoi), the scallop (Argopecten pupuratus), the gastropod (Xanthochorus cassidiformis) and the crab (Cancer polyodon) are harvested intensively. The impacts of harvesting these resources exclusively in the seagrass, sand‐gravel, and in the sand habitats, as well as, in the seagrass and sand‐gravel and in all habitats were assessed. The goal was to explore policies of sustainable exploitation of the benthic systems.
The most important findings were: (a) Fishing exclusively in either the seagrass or sand habitats produces a population increase in the sea star Luidia magallanica, in the seagrass Heterozostera tasmanica, and in the crab Paraxanthus barbiger. (b) Exclusive fishing in the sand‐gravel habitat causes only small effects on the species and groups, which suggests that this habitat is the most resistant to harvest. (c) The simultaneous fishing on two or three habitats would produce the largest negative effect on the entire system. Therefore, a habitat rotation fishery is recommended.
Our study suggests that trophic‐spatially explicit models offer great possibilities for the screening and planning of effective interventions or manipulations of natural systems.

Frameworks for marine conservation — non‐hierarchical approaches and distinctive habitats
Authors: Roff John C. , Evans Susan M.J. 
Published: November 2002

AbstractConservation efforts have traditionally been directed to ‘flagship’ species (whales, seals, migratory birds, etc.) that capture public attention. Often these flagship species occupy distinctive habitats. Distinctive habitats appear to be distinguished because of anomalous physical structures and unique oceanographic processes occurring within them, whereas representative habitats are not notable in this way. Distinctive habitats are found in areas of various physical anomalies described primarily by temperature, chlorophyll and topography.Several different kinds of distinctive habitats can be defined by their anomalous physical structures and oceanographic and biological processes. Species diversity may be either higher or lower in distinctive than in representative habitats. Distinctive habitats predominantly belong to a class of environments called ‘ergoclines’, and are typically associated with elevated resources at some ‘trophic level’.These elevated resources may be either the product of true production (i.e. they are generated (in situ), or they are the product of physical accumulation due to circulation mechanisms. These processes lie at the heart of the ecology of distinctive habitats, and are fundamental to maintenance of ecosystem health, ecological integrity, distributions, abundances and recruitment of species, patterns of animal migrations, and potential or actual fisheries yields.Conservation strategies need to examine the relationships between distinctive and representative habitats and species diversity. A strategy, leading from studies on flagship or other focal species, could have several advantages. It should rejuvenate the inherent appeal and significance of ‘species’ approaches to marine conservation, provide a rationale for human interest and a new foundation for examination of marine ecological interactions. It would also require a novel synthesis of relationships between ‘species’ and ‘spaces’ approaches to marine conservation by asking how we can take the best advantage of both approaches, rather than seeing them as in conflict.Copyright © 2002 John Wiley & Sons, Ltd.
