Published: September 2024

In a period, when the risk of environmental distortions becomes higher and more unpredictable, business struggle to carry on or even stay in business is obvious, unless they are able to adjust their strategies properly. This paper takes business model innovation as the primary strategic response to environmental turbulence into account. Through an advanced empirical methodology, this study looks at the long-term results of diverging businesses from various industries moving toward a cutting edge adaptation plot instead of those that contended for the simple replication of those that already existed. The analysis, first and foremost, demonstrates significant disparities in prosperity rates, which may be attributed to interplay of evolving business strategies and market dynamics along with organizational resources and capabilities. In addition to this, the document presents strategic foresight and the imperative of agility as a means of creating a platform where innovation and sustainable growth are realizable. The results provide a detailed framework for CEOs, owners and politicians, underscoring the imperative of avant-garde techniques that will enable them to adapt effectively to the continuously evolving market environment.

Medidas de eficiencia digital: Presentación de escritos procesales mediante registros electrónicos
Authors: de Diego Díez L. Alfredo
Published: September 2024

Hoy en día, la práctica de los actos de comunicación (desde el órgano judicial hacia las partes o terceros) y la presentación de escritos procesales en la oficina judicial tiende a realizarse completamente por medios electrónicos. Usar aplicaciones para las tareas más cotidianas se enmarca en el día a día de los ciudadanos, y la Administración de Justicia no podía quedar atrás, como un dinosaurio en la era tecnológica. Se habla, así, de e-Justicia (justicia electrónica), como concepto referido a «los esfuerzos de la Administración de Justicia para implementar todas las nuevas posibilidades derivadas del uso de Internet, para mejorar su funcionamiento interno, por ejemplo, reduciendo el número de papel físico, o para facilitar la relación con los ciudadanos, permitiendo que pudieran presentar escritos en soportes digital y, por ejemplo, sin necesidad de presentarlos de forma presencial y sujetos a algún horario».
Los nombramientos discrecionales en la carrera fiscal
Authors: Viada Bardají Salvador
Published: September 2024

El presente artículo recoge el modo de hacer los nombramientos discrecionales en la carrera fiscal, que, en el criterio del autor, responde a un auténtico sistema concebido para conseguir influencia política en la fiscalía por parte de los gobiernos, con independencia de su color político, dado que ambos comparten los efectos del sistema creado. El autor, fiscal del Tribunal Supremo, y que forma parte actualmente del Consejo Fiscal, órgano clave en materia de nombramientos discrecionales, explica hasta qué punto la libérrima decisión del fiscal general es determinante en que un fiscal obtenga la promoción a la que aspira, así como las posibilidades de control jurisdiccional de los nombramientos que pudieran obedecer a criterios arbitrarios.
¿Es el Tribunal Supremo español el tribunal independiente e imparcial que reclama la ley europea?
Authors: Lozano Ibáñez Jaime
Published: September 2024

La forma de elección de los vocales del Consejo General del Poder Judicial, así como de la elección, por estos, de los magistrados del Tribunal Supremo, permiten abrigar el temor de que, en algún momento, bien el TJUE, bien el TEDH, lleguen a declarar que el Tribunal Supremo español no es el órgano independiente e imparcial que exigen los textos europeos. Tanto la regulación legal de tales nombramientos, como los elementos fácticos concomitantes que los rodean, recuerdan, en algunos aspectos, al caso polaco. Esto, unido al prolongadísimo incumplimiento por España de las recomendaciones de organismos europeos en la materia permite que ese temor no sea completamente infundado.

Development and innovations in technology and vocational education in Nigeria
Authors: Obayi Anthony , Nwosu Rose Yeyeda , Ariwodo Felix Onyedikachi
Published: September 2024

The development and innovations in technology and vocational education could be a veritable instrument for national economic development in Nigeria. The growing awareness of the need to adapt technology and vocational education to meet the rapid global economic requirement is absolutely essential. Thus, technology and vocational education is a mechanism that could help for improving the quality of workforce by humanizing their mobility, adaptability and productivity. Technology and vocational education indirectly could contribute to the enhancement of firms' competitiveness in the globalized world. This is so because one of the most important features of technology and vocational education is its orientation towards the world of work and the emphasis of its curriculum on the acquisition of employable skills. It is important that government should focus on acquisition of employable skills for the youths so as to divert their attention from these social vices that have bedevil the nation. Thus, it is absolutely essential to examine the development and innovation achievable in technology and vocational education in Nigeria. It is concluded amongst others, that Nigeria government should look inward and recognize the fact that technology and vocational education as the bedrock for meaningful technological growth and national development. It is recommended that the government, stakeholders, policy makers in Nigeria should focus on technology and vocational education, quality assurance and best practices that have worked in advanced countries around the world. Also the government should adequately fund, plan, implement, and manage technology and vocational education programmes in technical institutions in Nigeria. Finally there should be a synergy between the school industry linkages and where students are trained must be a replica of the environment in which the students must subsequently work.
Determinants of Loan Repayment among Women Entrepreneurs in Oru East Local Government Area of Imo State, Nigeria
Authors: Ogbe Samuel , Akwaja S. , Osayi C.P.
Published: September 2024

The study focused on identifying the factors influencing loan repayment among women entrepreneurs in Oru East Local Government Area of Imo State, Nigeria. The specific objectives involved determining the socio economic characteristics of women entrepreneurs, sources of borrowing, rate of loan repayment, factors affecting loan repayment, and the importance of available loans to the respondents. The study used a simple random sampling technique to select 120 respondents. Primary data were collected through structured questionnaire and personal interviews. Data analysis involved the use of simple descriptive statistical tools such as means, percentages, and frequency distributions, a 4 point Likert scale, Ordinary Least Squares (OLS) regression model, Analysis of Variance (ANOVA), and Pearson Product Moment Correlation (PPMC). The findings revealed that the majority of the respondents were married (67%), young (58%), educated (100%), and experienced in handling financial and non financial issues (83%). Additionally, most respondents had large families that supported their enterprises through cheap labor and the supply of vital business information. The study also found that the majority of the respondents accessed their loans from formal financial institutions and had a moderate repayment rate of 54%. Significant variables influencing loan repayment among the respondents included age, operating costs, experience, income, and value of assets. Furthermore, the majority of the respondents agreed that loan availability benefitted them in expanding existing businesses, diversifying into new business lines, purchasing major inputs, and acquiring major assets. Based on these findings, the study recommended that loans should be extended to individuals with the necessary capacity to interact with formal financial institutions. Financial institutions should provide friendly and flexible policies to support loan repayment and create awareness among clients regarding the proper use of loans. Additionally, the government should consider subsidizing the price of inputs to reduce the financial burden and facilitate prompt loan repayment. These measures would ultimately stimulate the local economy, generate employment, and reduce poverty in the study area.
For Memoria Aeterna: Approaches to Immortality in Memory in Ancient Roman Funerary Monuments
Authors: Sun Yuanxin
Published: September 2024

When facing death, Ancient Romans attempted to achieve immortality through eternal memory. While the elites sought great achievements as invisible monuments, the non-elite Roman population depended on their tombs to preserve their identity and memory. By analyzing funerary monuments of the non-elite from the Late Republic to the first two centuries of the Roman Empire, this essay explores how their textual and visual components construct images that define and idealize the memory of individuals. The essay also investigates how these elements interact with the living to preserve and strengthen the memories of the dead: by connecting with family and friends from the private sphere in their regular visits as well as luring and informing strangers passing by from the public world. Finally, the essay sheds light on how the most important Roman festival for the dead, Parentalia, provided opportunities to appeal to both types of audiences in the preservation of memory.

A Fibrina Rica em Plaquetas (PRF) é um biomaterial autógeno derivado do sangue, usado por suas propriedades regenerativas para promover a cicatrização de tecidos. Na odontologia, o PRF melhora a regeneração óssea e tecidual em procedimentos cirúrgicos, como o tratamento de defeitos ósseos e recessões gengivais. Estudos recentes indicam que a utilização do PRF junto com tratamentos convencionais de periodontia, como raspagem e alisamento radicular, potencializa a regeneração tecidual. Integrar PRF nos tratamentos periodontais pode melhorar significativamente os resultados clínicos e a qualidade de vida dos pacientes. Avaliar a eficácia do Fibrina Rica em Plaquetas (PRF) no tratamento periodontal, na regeneração de tecidos periodontais e na cobertura radicular. Revisão da literatura, incluiu como critérios de busca na base de dados PubMed para identificar estudos relevantes sobre o uso de PRF no tratamento periodontal. A busca foi limitada a artigos publicados em inglês entre 2023 e 2024.

Published: September 2024

O presente artigo visa fazer uma análise acerca da situação em que figura como autuada, em um auto de prisão em flagrante delito, uma pessoa que esteja em uma das hipóteses do art. 318 do Código de Processo Penal, dispositivo normativo que prevê as hipóteses de cabimento da substituição da prisão preventiva pela prisão domiciliar. Objetiva, ainda, propor um novo paradigma de atuação do(a) Delegado(a) de Polícia, como presidente do auto de prisão em flagrante delito, nesses casos específicos. O artigo se propõe, portanto, a analisar se seria juridicamente possível - à luz do Código de Processo Penal, da Constituição Federal, do Estatuto da Criança e do Adolescente e de normativas internacionais de direitos humanos das quais o Brasil é signatário – o não encaminhamento do(a) autuado(a) ao sistema prisional, após o término do auto de prisão em flagrante, quando tal pessoa fizer jus à prisão domiciliar.
Necropolítica no Brasil contemporâneo: reconfigurações pós-coloniais e a construção do “Outro” como um “Não-ser” para fazer morrer
Authors: Cândido Maíra Dias
Published: September 2024

O presente artigo busca relacionar o conceito de necropolítica, elaborado pelo camaronês Achille Mbembe, ao domínio das relações raciais no Brasil,  identificadas desde o período escravocrata e que, nos dias atuais, funcionam como  estratégias políticas fundamentais para separar e dominar classes e raças. A  abordagem ocorre em diálogo com a teoria do Labelling Approach e com a ideia de  reificação, tendo em vista a subserviência do direito penal a uma classe dominante,  conferindo tratamento diferenciado aos crimes cometidos pelas massas  desfavorecidas, compostas majoritariamente por negros e periféricos. Esses grupos  indesejáveis são, sob à ótica política e econômica vigente, inscritos no paradigma do  “Outro”, ou seja, um “Não-ser”. Buscou-se analisar dados oficiais e oriundos da  sociedade civil organizada, que desvelam alguns mecanismos pelos quais a  necropolítica se operacionaliza no Brasil. Diante do fato de que a lógica colonial ainda  se perpetua a construção de uma sociedade menos desigual e menos hierarquizada  pressupõe o enfrentamento do racismo e das estruturas de poder que insistem na sua manutenção.
Reflexões sobre o suicídio policial a partir da teoria do reconhecimento de Axel Honneth
Authors: Lima Marianna Cardoso Horta de
Published: September 2024

O suicídio entre policiais é um fenômeno complexo e multifatorial, cuja compreensão requer a integração entre diversas perspectivas interpretativas. As expressivas taxas de sua incidência entre policiais demanda do poder público a implementação de políticas de prevenção, as quais imprescindem de conhecimento dos fatores que influem, razão pela qual se justifica o desenvolvimento de pesquisas. As discussões centrais desse artigo permeiam a possibilidade de se analisar o suicídio policial sob a perspectiva da Teoria do Reconhecimento do filósofo e sociólogo Axel Honneth, bem como o potencial para desencadear luta por reconhecimento. Para tanto, foram realizadas pesquisas bibliográficas sobre o fenômeno do suicídio policial e os fatores de riscos identificados por pesquisas empíricas realizadas no âmbito nacional, com o intuito de verificar a existência ou não de apontamentos e experiências de desrespeito vivenciadas por profissionais de segurança pública e o seu potencial para desencadear a luta por reconhecimento.
A investigação da lavagem de dinheiro como forma eficiente de combate ao tráfico de droga
Authors: Pereira Zelina Lisley , Guimarães Lucas Eduardo
Published: September 2024

Este artigo busca discutir a investigação de lavagem de dinheiro comoforma eficaz no combate ao tráfico de drogas, pois percorrendo o caminho do dinheiro lavado é possível identificar todos os envolvidos no esquema criminoso, desde varejistas de drogas até financiadores, além de permitir o confisco dos recursos adquiridos ilegalmente, descapitalizando o tráfico e tornando-o inviável. Levantamento realizado pela pesquisa revelou que, de 2007 a 2017, ocorreram quase duas mil vezes mais prisões de traficantes indiciados pelo artigo 33 que pelo artigo 36 da Lei 11.343/2006 em Minas Gerais. Isso demonstra que o combate se concentrou na prisão de pequenos traficantes de drogas, o que contribuiu para o encarceramento em massa destes. No entanto, não resolveu o problema do financiamento, que mantém o tráfico em atividade. Essa atuação do sistema penal confirma a teoria do Etiquetamento Social.
Diálogos entre a mediação de conflitos e a prática policial no ambiente escolar
Authors: Veloso Verenna Laurenn Vidal de Assis
Published: September 2024

A mediação de conflitos é um dos meios de se assegurar a resolução, de fato, dos litígios, tendo em vista que possui como princípio o diálogo entre as partes e não há uma determinada competitividade entre os sujeitos, de modo que, ao ser empregada na escola, tenta proporcionar aos alunos um ambiente pacífico e harmonioso. A prática policial no ambiente escolar possui como objetivo principal garantir a segurança de todos os sujeitos presentes naquele ambiente, considerando que os índices de violência escolar têm crescido de modo alarmante. Dessa forma, o objetivo desse artigo é analisar a utilização da mediação de conflitos e da prática policial no ambiente escolar, demonstrando como esses dois meios de obtenção de um espaço de conhecimento harmônico podem coexistir. Por meio da atuação conjunta dos policiais com a sociedade, a mediação pode ser uma das formas utilizadas para que se obtenha e se concretize a segurança pública nas instituições de ensino.

Authors: Pamplona Gleice Messias Cardoso , Caldeira Thalita Almeida
Published: September 2024

O presente artigo aborda a evolução das leis relacionadas a crimes sexuais na história do Brasil, destacando como essas transformações refletiram a compreensão e na definição desses crimes ao longo do tempo. O propósito central é analisar como as leis brasileiras abordaram esses crimes ao longo dos séculos, ressaltando as mudanças na visão da sociedade sobre eles. Para essa análise, utiliza-se uma abordagem histórica que revisa as mudanças legais desde o período colonial até os dias atuais, considerando também os aspectos socioculturais que moldaram a percepção desses crimes. Observa-se que as transformações legislativas não se limitaram às leis, refletindo também em transformações sociais e culturais. Apesar do progresso das leis em direção aos direitos humanos e à dignidade das vítimas, há ainda desafios a serem superados, principalmente devido à persistência de uma cultura machista e patriarcal. Portanto, enfatiza-se a importância de promover mudanças culturais profundas para complementar as mudanças legais e garantir a eficácia na proteção das vítimas de crimes sexuais.

Mechanistic target of rapamycin (mTOR) pathway in Sertoli cells regulates age-dependent changes in sperm DNA methylation

Published: September 2024

Over the past several decades, a trend toward delayed childbirth has led to increases in parental age at the time of conception. Sperm epigenome undergoes age-dependent changes increasing risks of adverse conditions in offspring conceived by fathers of advanced age. The mechanism(s) linking paternal age with epigenetic changes in sperm remain unknown. The sperm epigenome is shaped in a compartment protected by the blood-testes barrier (BTB) known to deteriorate with age. Permeability of the BTB is regulated by the balance of two mTOR complexes in Sertoli cells where mTOR complex 1 (mTORC1) promotes the opening of the BTB and mTOR complex 2 (mTORC2) promotes its integrity. We hypothesized that this balance is also responsible for age-dependent changes in the sperm epigenome. To test this hypothesis, we analyzed reproductive outcomes, including sperm DNA methylation in transgenic mice with Sertoli cell-specific suppression of mTORC1 (Rptor KO) or mTORC2 (Rictor KO). mTORC2 suppression accelerated aging of the sperm DNA methylome and resulted in a reproductive phenotype concordant with older age, including decreased testes weight and sperm counts, and increased percent of morphologically abnormal spermatozoa and mitochondrial DNA copy number. Suppression of mTORC1 resulted in the shift of DNA methylome in sperm opposite to the shift associated with physiological aging – sperm DNA methylome rejuvenation and mild changes in sperm parameters. These results demonstrate for the first time that the balance of mTOR complexes in Sertoli cells regulates the rate of sperm epigenetic aging. Thus, mTOR pathway in Sertoli cells may be used as a novel target of therapeutic interventions to rejuvenate the sperm epigenome in advanced-age fathers.

CSQUiD: an index and non-probability framework for constrained skyline query processing over uncertain data
Authors: Lawal Ma'aruf Mohammed , Ibrahim Hamidah , Mohd Sani Nor Fazlida , Yaakob Razali , Alwan Ali A.
Published: September 2024

Uncertainty of data, the degree to which data are inaccurate, imprecise, untrusted, and undetermined, is inherent in many contemporary database applications, and numerous research endeavours have been devoted to efficiently answer skyline queries over uncertain data. The literature discussed two different methods that could be used to handle the data uncertainty in which objects having continuous range values. The first method employs a probability-based approach, while the second assumes that the uncertain values are represented by their median values. Nevertheless, neither of these methods seem to be suitable for the modern high-dimensional uncertain databases due to the following reasons. The first method requires an intensive probability calculations while the second is impractical. Therefore, this work introduces an index, non-probability framework named Constrained Skyline Query processing on Uncertain Data (CSQUiD) aiming at reducing the computational time in processing constrained skyline queries over uncertain high-dimensional data. Given a collection of objects with uncertain data, the CSQUiD framework constructs the minimum bounding rectangles (MBRs) by employing the X-tree indexing structure. Instead of scanning the whole collection of objects, only objects within the dominant MBRs are analyzed in determining the final skylines. In addition, CSQUiD makes use of the Fuzzification approach where the exact value of each continuous range value of those dominant MBRs’ objects is identified. The proposed CSQUiD framework is validated using real and synthetic data sets through extensive experimentations. Based on the performance analysis conducted, by varying the sizes of the constrained query, the CSQUiD framework outperformed the most recent methods (CIS algorithm and SkyQUD-T framework) with an average improvement of 44.07% and 57.15% with regards to the number of pairwise comparisons, while the average improvement of CPU processing time over CIS and SkyQUD-T stood at 27.17% and 18.62%, respectively.
Effects of direction specific exercise training on athletic performance: a systematic review and meta-analysis
Authors: Huang Jiaru , Hortobágyi Tibor , Dos’Santos Thomas , Shi Yu , Que Yilin , Lin Junlei , Su Yuying , Li Wei
Published: September 2024

Background

The similarity between movement patterns and force-vector specificity of training exercises and the target movement will likely result in the greatest transfer of the practiced skills and physical abilities to the intended sports skill performance. Therefore, this review aimed to investigate whether specific adaptations in athletic performance would be observed following direction specific exercise training.

Methodology

The literature search was performed in PubMed, Web of Science, and MEDLINE. Studies comparing acute (post-activation potentiation enhancement) and short-term (>2 weeks) effects of horizontally vs. vertically oriented resistance and plyometric training on athletic performance of recreationally active participants of either sex were included. The effect sizes were determined using a robust variance estimation random-effects model and were reported as Hedge’s g.

Results

Twenty-two studies were included. For acute studies (n = 4), a small non-significant effect favoring horizontal training (HT) for sprint performance improvements (g = −0.19, p = 0.17) was evident. For short-term studies (n = 18), the results showed non-significant, small to large differences between HT and vertical training (VT) in pooled vertical and horizontal jump improvements (g = 0.06, p = 0.67), vertical (g = 0.21, p = 0.17) and horizontal jump (g = −0.15, p = 0.40), pooled vertical and horizontal maximal strength (g = 0.27, p = 0.42), horizontal (g = −0.83, p = 0.16) and vertical maximal strength (g = 0.78, p = 0.28), pooled short and medium distance sprint (g = −0.23, p = 0.16), short (g = −0.33 [−0.85, 0.19], p = 0.19) and medium (g = −0.12 [−0.37, 0.13], p = 0.28) distance sprint, and COD speed and maneuverability (g = −0.45, p = 0.26).

Conclusions

HT and VT were both equally effective in improving vertically and horizontally athletic performance, potentially refuting the theory of directional specificity of training on athletic performance outcomes.

The microbiota of hydrothermal vents has been widely implicated in the dynamics of oceanic biogeochemical cycling. Lithotrophic organisms utilize reduced chemicals in the vent effluent for energy, which fuels carbon fixation, and their metabolic byproducts can then support higher trophic levels and high-biomass ecosystems. However, despite the important role these microorganisms play in our oceans, they are difficult to study. Most are resistant to culturing in a lab setting, so culture-independent methods are necessary to examine community composition. Targeted amplicon surveying has become the standard practice for assessing the structure and diversity of hydrothermal vent microbial communities. Here, the performance of primer pairs targeting the V3V4 and V4V5 variable regions of the SSU rRNA gene was assessed for use on environmental samples from microbial mats surrounding Kama‘ehuakanaloa Seamount, an iron-dominated hydrothermal vent system. Using the amplicon sequence variant (ASV) approach to taxonomic identification, the structure and diversity of microbial communities were elucidated, and both primer pairs generated robust data and comparable alpha diversity profiles. However, several distinct differences in community composition were identified between primer sets, including differential relative abundances of both bacterial and archaeal phyla. The primer choice was determined to be a significant driver of variation among the taxonomic profiles generated. Based on the higher quality of the raw sequences generated and on the breadth of abundant taxa found using the V4V5 primer set, it is determined as the most efficacious primer pair for whole-community surveys of microbial mats at Kama‘ehuakanaloa Seamount.

A study was conducted to evaluate the macro and micronutrient levels in the soil under the sugarcane-wheat cropping sequence and its relationship with soil characteristics. Understanding the nutrient status is vital for the efficient application of fertilizers, as widespread deficiencies in both macro and micronutrients are being reported in the soils of Uttar Pradesh. The rice-sugarcane cropping sequence is a prominent practice in the northwestern plains of Uttar Pradesh and Uttarakhand, covering 10-11% of the net cultivated area in these regions. Over recent years, sugarcane and wheat yields have plateaued in these areas due to declining factor productivity. Soil samples were collected from depths of 0-15 cm, 15-30 cm, and 30-45 cm at four locations in the Muzaffarnagar and Ghaziabad districts under the rice-sugarcane sequence. The available zinc content in the surface soil (0-15 cm) ranged from 0.605 to 0.883 mg/kg, and in the sub-surface soil (30-45 cm), it varied between 0.111 to 0.629 mg/kg, with an average of 0.083 mg/kg in surface soil and 0.435 mg/kg in sub-surface soil. A correlation analysis between various soil properties across different locations at three soil depths (0-15 cm, 15-30 cm, and 30-45 cm) was also conducted. The findings indicated that the soils are generally low in nitrogen, low to medium in phosphorus and potassium, and sufficiently supplied with copper, iron, manganese, and zinc in the surface layer. Future research on nutrient distribution in these areas will help advance precision agriculture, improve fertilizer management, and boost crop productivity while minimizing environmental harm. This research will contribute to sustainable soil management, economic benefits for farmers, and provide valuable insights for regional agricultural policies, further supporting food security.

The investigation included eight different weed control techniques i.e. T1 -weedy check, T2 - weed free, T3 - hand weeding at 30 DAS, T4 - 2, 4-D @ 0.5 kg a.i. ha-1 + Sulfosulfuron @ 0.02 kg a.i. ha-1 at 30 DAS,T5 - Pendimethalin @ 1.5 kg a.i. ha-1(P.E) + Quizalofop-ethyl @ 50 gm a.i ha-1 (PoE at 25 DAS) + one hand weeding, T6 - 2, 4-D @ 0.5 kg a.i. ha-1, T7 - 2, 4-D @ 0.5 kg a.i. ha-1 + one hand weeding at 30 DAS, T8 - 2, 4-D @ 0.5 kg a.i. ha-1 + two hand weeding at 30 and 45 DAS.
Results: The investigation found that the most effective ways to control weeds are by keeping the area completely weed free by using pendimethalin @ 1.5 kg a.i. ha-1(P.E) + Quizalofop-ethyl @ 50 gm a.i ha-1(PoE at 25 DAS) + one Hand weeding (Treatment T2) was found the most successful in terms of achieving the lowest weed density and highest weed control efficiency. Application of pendimethalin
@ 1.5 kg a.i. ha-1(P.E) + Quizalofop-ethyl @ 50 gm a.i ha-1 (PoE at 25 DAS) + one hand weeding was found to be better than using herbicides to reduce weed infestation in wheat crops.
Conclusion: Based on the results, it can be concluded that integrated weed management practices weed-free treatment was the most effective option for managing weeds in wheat.

A study was conducted for two years during 2022 and 2023 at Regional Agricultural Research Station, Warangal, Telangana, India to know the virulence of gall midge on rice varieties with known gall midge resistant genes at Warangal. During both the years i.e., 2022 and 2023, the virulence of gall midge was low in Aganni followed by Akshayadhan, W1263 and Purple. The gall midge virulence was very low and similar in Aganni and Akshayadhan which reveals the efficacy of gall midge resistance genes i.e., Gm4 and Gm8 against gall midge biotype 4M at Warangal. Since Purple variety does not have any gall midge resistant genes, gall midge virulence was highest on Purple variety. The study revealed that, gall midge genes viz., Gm4 and Gm8 are holding good for resistance against gall midge biotype 4M in both the years of study. However, a close monitoring of the virulence pattern in endemic areas is important for deployment of effective genes in developing resistant varieties.

In vivo toxicity and antifungal therapeutic evaluation of selected natural compounds for topical applications was analyzed using standard methods. The natural compounds, blue vitriol, brimstone, trona, alum, palm ash and black stone were hygienically selected and purchased at a local market in southeastern Nigeria. The test organisms were isolated from high vaginal swab specimens obtained from cases of cutaneous candidiasis. The isolates were identified based on their morphological, physiological and molecular characteristics. The toxicological screening of the test samples was done using Draize’ skin irritancy test, Murine local lymph node assay (LLNA) and necropsy. The in vivo evaluation of antifungal activity of the solutions was done using eight-week-old albino rats weighing 120g – 150g. The animals were infected with the Candida isolates percutaneously; and treated using various formulations of the natural compounds. The skin sections were carefully observed for histopathological changes, before and after treatment. The total yeast counts of the infected skin tissues were also determined. The isolates include Candida albicans, C. glabrata, C. parapsilosis and C. tropicalis. Draize’ skin test and Murine local lymph node assay showed no observable skin irritancy reaction (P>0.05). The normal skin architecture of the infected animals was restored after 5 days of treatment with the test samples; while the total yeast count decreased from 108 CFU/mL to 102 CFU/mL. The findings have revealed that natural compounds are effective as well as non-toxic topically, in treatment of cutaneous candidiasis.

Isometric log ratios of proportions of major ions, derived from intuitive sequential binary partitions, are used to characterize hydrochemical variability within and between coal seam gas (CSG) and surrounding aquifers in a number of sedimentary basins in the USA and Australia. These isometric log ratios are the coordinates corresponding to an orthonormal basis in the sample space (the simplex). The characteristic proportions of ions, as described by linear models of isometric log ratios, can be used for a mathematical‐descriptive classification of water types. This is a more informative and robust method of describing water types than simply classifying a water type based on the dominant ions. The approach allows (a) compositional distinctions between very similar water types to be made and (b) large data sets with a high degree of variability to be rapidly assessed with respect to particular relationships/compositions that are of interest. A major advantage of these techniques is that major and minor ion components can be comprehensively assessed and subtle processes—which may be masked by conventional techniques such as Stiff diagrams, Piper plots, and classic ion ratios—can be highlighted. Results show that while all CSG groundwaters are dominated by Na, HCO3, and Cl ions, the proportions of other ions indicate they can evolve via different means and the particular proportions of ions within total or subcompositions can be unique to particular basins. Using isometric log ratios, subtle differences in the behavior of Na, K, and Cl between CSG water types and very similar Na‐HCO3water types in adjacent aquifers are also described. A complementary pair of isometric log ratios, derived from a geochemically‐intuitive sequential binary partition that is designed to reflect compositional variability within and between CSG groundwater, is proposed. These isometric log ratios can be used to model a hydrochemical pathway associated with methanogenesis and/or to delineate groundwater associated with high gas concentrations.
