Mathematical black box models, which hide the structure and behavior of the subsystems, currently dominate science. Mechanisms under study remain hidden. Errors and paradoxes, such as the biodiversity paradox and the limiting similarity hypothesis, often arise from subjective interpretations of these hidden mechanisms. To address these problems in ecology, we have developed transparent mathematical models of the white box type. Here we present and justify the hypothesis that it is possible to construct transparent mathematical white-box models using logical deterministic cellular automata, where the rules used to construct these models are based on the general theory of the relevant domain. So far, white box modeling has allowed us to directly identify the mechanisms of interspecific competition, to test the principle of competitive exclusion and the hypothesis of limiting similarity, to resolve the paradox of biodiversity, and to formulate for the first time the general principle of competitive coexistence. As a framework for reproducing and further developing the method, we present C++ code of two transparent mathematical models of an ecosystem. A shift to transparency in the mathematical modeling paradigm has the potential to revolutionize scientific research and to advance knowledge and technology in a wide variety of domains.

En el dinámico mundo del marketing y los negocios, la capacidad de aprender de las experiencias ajenas se ha convertido en un activo invaluable. La colaboración entre mentes empresariales puede dar lugar a una sinergia única, generando relaciones mutuamente beneficiosas para todas las partes involucradas. Este enfoque no solo transforma la forma en que operamos nuestros negocios, ya sea en línea o fuera de línea, sino que también puede abrir nuevas perspectivas y oportunidades inexploradas. Cambiando la Perspectiva del Marketing Al mirar el marketing como una oportunidad para establecer relaciones sólidas y beneficiosas, se abre un horizonte de posibilidades. En lugar de verlo como una simple estrategia para vender productos o servicios, se puede entender como una herramienta para construir conexiones duraderas. Este cambio de perspectiva puede marcar la diferencia en la forma en que se abordan las estrategias de marketing, centrándose en la creación de valor para los clientes y estableciendo relaciones a largo plazo. Uniendo Mentes para Crear una Tercera Experiencia La colaboración entre empresas no solo implica compartir experiencias, sino también fusionar ideas y perspectivas para crear una tercera experiencia única. Al conectar con otras personas cuyas experiencias son similares, pero que operan en diferentes mercados, se amplían las posibilidades de aprendizaje y crecimiento. Este intercambio de conocimientos puede ser particularmente valioso para aquellos que buscan explorar el mundo del negocio en línea.

Investigation of foot-and-mouth disease outbreaks in the Mbala and Kazungula districts of Zambia2014 •
Foot-and-mouth disease (FMD) is an acute, highly contagious viral infection of domestic and wild cloven-hoofed animals. It is known to be endemic in Zambia, with periodic outbreaks occurring in different geographical areas of the country. This study was conducted to investigate the presence of FMD virus (FMDV) in reported FMD-suspected cases in cattle from the Kazungula and Mbala districts of Zambia. Sixty epithelial tissues or oesophageal-pharyngeal (OP) scrapings (probang samples) were collected from Mbala (n = 51) and Kazungula (n = 9) and examined for FMDV. The FMDV viral RNA and serotypes were examined by realtime reverse transcription polymerase chain reaction (qRT-PCR) and antigen Enzyme- linked immunosorbent assay (ELISA), respectively. Twenty-two samples (36.7%) were positive for the FMDV genome by qRT-PCR with Cycle threshold (Ct) values ranging from 13 to 31. The FMDV-positive samples from epithelial tissues showed relatively higher Ct values compared to those obtained fr...

The article presents one of the possible options for improving the methodology for identifying zones of potential soil fertility. The necessity of using areal interpolation as the only method of geostatistical analysis that takes into account the area of input objects is proved. To check the data for a Gaussian normal distribution, it is necessary to use several verification met- hods, since when evaluating only statistical parameters, significant (in the case of phosphorus, abnormal) deviations were found, however, when evaluating histograms and quartile-quartile plots, it is necessary to bring the data to a normal distribution was relevant only for humus and phosphorus. The main advantages and disadvantages of the areal interpolation method are shown. With a significant deviation from the normal distribution, in the absence of built-in fun- ctions for automated reduction of data to the Gaussian distribution, one of the few ways can be the logarithm of the data. After zoning, it is necessary to perform a reverse translation to the ori- ginal values for a representative visualization of the results. As a result of the selection of the- oretical semivariograms-deconvolutions, the degrees of spatial dependence and optimal distances for the studied properties are determined. It is clear that the lag of acidity and potassium content is 1000 m and 1050 m, respectively. For phosphorus, it is 1300 m. For the humus content, the lag is much lower – 440 m. The maximum autocorrelation distance is typical for potassium and humus – 2330 and 1528 m; the minimum for phosphorus is 637. The reliability of the cartograms of agrochemical properties is confirmed by the calculated root-mean-square errors. The deviations of pH values are in the range of up to 0.15 units. The highest mean square error of interpolation is observed in weakly acidic soils. The error in the interpolated values of humus from the initial data is inherent in anthropogenically transformed soils. The root-mean-square error of phosphorus values can be estimated as insignificant. The largest errors in K2O – in isolated cases, they reach 120 mg/ha in the central and eastern parts of the region. The resulting map of potential soil fertility was used to determine the relationship with the granulometric composition of soils. A low level is observed on sandy and sandy loam soils, a high level – on loams. Also, the productivity is affected by the relief of the territory – in the dissected areas, productivity is lower than on the plains.

Analisis kesalahan berbahasa Indonesia di kalangan masyarakat yang di sebabkan penggunaan bahasa gaul2023 •
Bahasa merupakan hal yang penting dalam kehidupan manusia. Melalui manusia dapat saling berkomunikasi. Suatu bahasa harus memiliki makna yang jelas agar saat terjadai komunikasi tidak terjadi sebuah kesalah pahaman dalam penyampaiannya. Saat ini sudah terdapat beberapa variasi gaya bahasa yang digunakan di kalangan masyaarakat. Adanya variasi gaya bahasa dipicu oleh perkembangan teknologi komunikasi yang berkembang sangat pesat. Adanya perkembangan bahasa ini membuat gaya bahasa yang digunakan oleh generasi ke generasi berbeda – beda. Setiap generasi akan memilliki ciri khas gaya bahasanya masing – masing. Penggunaan bahasa Indonesia yang baik dan benar saat ini sudah mulai tergeser keberadaannya oleh bahasa gaul dan merasa terbiasa menggunakan bahasa gaul.

A Atencao Primaria em Saude (APS) faz uso de diversas estrategias para que seus principios doutrinarios sejam satisfatorios, com o surgimento da necessidade de dar suporte a Estrategia da Saude da Familia (ESF), foi implementado no Sistema Unico de Saude (SUS) o Nucleo de Atencao a Saude da Familia (NASF), em 2008. Tendo como objetivo identificar o suporte da assistencia de enfermagem junto ao NASF. Buscando analisar a tematica proposta, este projeto tratou de uma pesquisa qualitativa exploratoria realizada na Unidade Basica de Saude Dr. Nelson de Andrade Sales do municipio de Ibaretama-CE. Colaboraram com a entrevista a coordenadora do NASF e a Enfermeira da unidade, apos assinado o Termo de Consentimento Livre e Esclarecido (TCLE) pelas participantes, as mesmas responderam um instrumento formulado pelas autoras da pesquisa que correspondeu a um questionario com as principais questoes: Como e a atuacao do NASF? Quais os projetos voltados para a enfermagem? A atuacao do enfermeiro d...
