Adecuación y optimización del funcionamiento y operación del sistema de tratamiento de aguas residuales industriales de la planta Beneficio C.I. Tequendama S.A.
No full textLa Agro- industria de la palma de aceite en Colombia, es una gran fuente generadora de efluentes (lodos y aguas residuales) con altas cargas contaminantes, además de ser muy ácidas y con temperaturas elevadas, por lo cual, para ser vertidas deben ser tratadas o depuradas en un Sistema de Tratamiento de Agua Residuales (STAR), que en algunas ocasiones no son eficientes, provocando que la calidad de los vertimientos no sea la mejor. A veces estos vertidos no cumplen con los límites permisibles de vertimientos establecidos en la legislación ambiental colombiana (decreto 1594/84) C.I. TEQUEDAMA S.A. (División Extractora) es una de las compañías del Grupo Daabon Orgánica que se dedica a la Extracción de Aceite Crudo de palma Orgánica y por su Sostenibilidad Ambiental ejecuta proyectos que ayudan a preservar y conservar el medio ambiente, mejorando la calidad de vida humana, el entorno que lo rodea y el cumplimiento con la legislación ambiental colombiana. En este informe se muestra la participación directa del Autor en la Adecuación y Optimización del Funcionamiento y Operación del Sistema de Tratamiento de Aguas Residuales de la Planta Beneficio C.I.

An interbehavioral analysis of educational processes [Un Análisis Interconductual de los Procesos Educativos]
No full textThis paper offers a broader and deeper view of functional analysis of educational processes as sustained by interbehavioral psychology. It describes the basis of a theoretical model based on this perspective, aimed to guide teachers' and students' practices, curriculum planning, and evaluation of educational achievements. In its first part, the paper outlines some important principles of interbehavioral psychology, its possible metatheoretical contributions to the study of educational events, and a conceptual framework of educational factors and their interactions. Then, it deals with the concept of 'competence', considered as a valuable analytic unit of academic learning, its most important dimensions, and overviews some conditions necessary for the generation of competencies related to different levels of aptitude. Finally, the elements of a methodological and operational paradigm for a systematic analysis of educational factors and processes are described

Silene astartes C.I. Blanche ex Boiss., Fl. Orient. Suppl.
No full textSilene astartes C.I. Blanche ex Boiss., Fl. Orient. Suppl.: 102. 1888. Lectotypus (designated here): Lebanon . Prov. Mount-Lebanon: Djebaïl, ruines d’AFka, VI-VII.1880, fl. & Fr., Blanche 55 (G-BOIS [G00330604]!; isolecto-: BEI!, G [G00341654]!) (Fig. 1). Notes. – Boissier (1888) published S. astartes in the “Supplementum oF the Flora Orientalis”. He wrote “ S. astartes (Blanche in litt.)” beFore the Latin description. Ŋe mention oF Blanche as the author “in litt.” by Boissier has been interpreted in different ways in the literature. Floras oF Lebanon have cited only C.I. Blanche as the author oF the species (sometimes with the mention “in Boiss.”; Post, 1896, 1932; ThiÉbaut, 1936; Mouterde, 1966; TohmÉ & TohmÉ, 2007), whereas BouloumoY (1930) interpreted the authorship as “Boiss. et B.” [Boiss. & C.I. Blanche]. In the Boissier’s Herbarium oF the “Flora Orientalis” (G-BOIS), Blanche 55 contains a handwritten note by Blanche himselF with a Latin description oF the species (Fig. 1). However this description differs considerably From the protologue where Boissier published a new and more complete description by validating the name (Boissier, 1888: 102). We thereFore ascribe Boissier as the author oF S. astartes in accordance with Greuter et al. (1984) and not as C.I. Blanche as mentioned in the latest flora oF Lebanon treatment (TohmÉ & TohmÉ, 2007). Boissier (1888) clearly cited two gatherings in the protologue: “Hab. in Libano supra Djebail ad minas AFka (Bl.!)” and “ad Ain SuFar (Peyron!)”. Only Blanche 55 [G00330604] is present in G-BOIS. We Found three duplicates oF the Peyron collection at G and one at P. Each oF them bears the locality “Ain SuFar” and are dated June 11, 1882. Two oF them have the collection number 1379 mentioned [G00341656, P04987226]) and two [G00341655, G00341657] without any number. All these collections have a glandular-pubescent calyx and match Fully with S. italica (L.) Pers. and not with S. astartes, which has a calyx always glabrous. ŊereFore, we choose Blanche 55 housed at G-BOIS as the lectotype, which is the only material present at G-BOIS and exclude the remaining syntypes From S. astartes.Published as part of Pierre-Emmanuel Du Pasquier & Daniel Jeanmonod, 2016, Lectotypification of three species of Silene sect.

Analysis of the labor guarantees provided to C.I. Prodeco S.A workers, due to the returning process of mining titles in the department of Cesar
No full textEn este proyecto de grado en la modalidad de práctica jurídico social, se brindó apoyo al área de derecho laboral individual y colectivo al Centro de Atención Laboral de Valledupar, con el fin de brindar asesoría jurídica a los trabajadores organizados en asociaciones sindicales en el sector minero energético, los cuales estaban siendo despedidos debido a la actual contingencia de devolución de títulos mineros por parte de la empresa C.I. PRODECO S.A., ante la negativa por parte de la Agencia Nacional de Minería de la suspensión de operaciones. Dentro de las actividades llevadas a cabo, se desplegaron acciones de tutela, derechos de petición, quejas y toda acción correspondiente que propendiera por la garantía de los derechos de los trabajadores; todo ello originado en las distintas brigadas jurídicas que se realizaron a lo largo de la práctica para poder tener conocimiento de los casos correspondientes y asimismo, orientar la ruta pertinente para cada trabajador, teniendo en cuenta que lo primordial ante este hito dentro de la minería colombiana era la defensa de los puestos de trabajo. Así las cosas, se realiza la presentación de los resultados evidenciados en el acompañamiento de asesoría jurídico dentro del Centro de Atención Laboral Valledupar, habida cuenta de los casos determinados y a los cuales se les dio seguimiento en el marco de la práctica jurídico socialPregradoAbogadoIn this degree project in the social legal practice modality, support was provided to the area of individual and collective labor law at the Valledupar Labor Attention Center, in order to provide legal advice to workers organized in union associations in the mining sector. energy, which were being fired due to the current contingency of returning mining titles process by the company C.I. PRODECO S.A., given the refusal by the National Mining Agency to suspend operations. Among the activities carried out, protection actions, petition rights, complaints and any corresponding action that tended to guarantee the rights of workers were done in order to support the legal practice; the latter actions named, were originated in the different legal brigades, that were carried out throughout the practice in order to be aware of the corresponding cases and also guide the pertinent route for each worker, taking into account that the essential thing before this milestone within Colombian mining it was the defense of jobs. Thus, the presentation of the results evidenced in the accompaniment of legal advice within the Valledupar Labor Attention Center is made, taking into account the specific cases and which were followed up within the framework of social legal practice.l Mining Agency to suspend operations
Establishing the test–retest reliability & concurrent validity for the repeat ice skating test (RIST) in adolescent male ice hockey players
No full textIn this study the authors examine the test–retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power and was validated with 3 anaerobic lab tests: (a) vertical jump, (b) the Margaria–Kalamen stair test, and (c) the Wingate Anaerobic Test. The participants (n = 14) were 11- to 12-year-old males selected from a Peewee “A” level ice hockey team (Thunder Bay, Canada). The results of the test–retest reliability estimation showed that the RIST was a reliable test at measuring average peak power in watts (R = .99, C.I.95% = 0.97 to 0.99) and watts per kilogram (R = .98, C.I.95% = 0.94 to 0.99). The RIST was also a valid test when correlated with the 3 anaerobic lab tests for measuring peak power in watts: vertical jump (r = .86, C.I.95% = 0.72 to 0.94), Margaria–Kalamen stair test (r = .66, C.I.95% = 0.39 to 0.83) and Wingate Anaerobic Test (r = .86, C.I.95% = 0.72 to 0.93). The test is considered promising because it does not require any specific equipment, and is a sport-specific, on-ice test, that can be administered during a regular ice hockey practice session
C.I. Acid Black 1 transfer from dilute solution to perlite framework in organic waste management
No full textDyes, considered as toxic and persistent pollutants, must be removed from organic wastes prior to their composting and application in sustainable agriculture. Azo dyes, capable of altering the physicochemical properties of soil, are difficult to expel by conventional wastewater treatments. C.I. Acid Black 1 (AB 1), a sulfonated azo dye, inhibits nitrification and ammonification in the soil, lessens the nitrogen use efficacy in crop production and passes substantially unaltered through an activated sludge process. The retention of C.I. Acid Black 1 by raw and expanded perlite was investigated in order to examine the potential effectiveness of this aluminosilicate material toward organic waste cleanup. Dye adsorption proved spontaneous and endothermic in nature, increasing with temperature for both perlites. Expanded perlite having a more open structure exhibited a better performance compared to the raw material. Several of the most widely recognized two-parameter theoretical models, i.e., Langmuir, Freundlich, Temkin, Brunauer–Emmett–Teller (BET), Harkins–Jura, Halsey, Henderson, and Smith, were applied to reveal physicochemical features characterizing the adsorption. The Langmuir, Freundlich, Temkin, BET, Henderson, and Smith equations best fitted experimental data indicating that the adsorption of anionic dye on perlites is controlled by their surface, i.e., non-uniformity in structure and charge. This heterogeneity of surface is considered responsible for promoting specific dye adsorption areas creating dye “islands” with local dye supersaturations. © The Author(s) 2024

Shared aperture array antennas composed of differently sized
No full textA novel solution for conceiving wide band (multi-band) array antennas is presented. The solution is based on the concept of interleaving sparse, sub-arrays operating at separate frequencies. Sparse array antennas offer two major advantages, namely: they have non-uniformly distributed elements, with possibly large distances between elements (this providing the necessary space for interleaving different sub-arrays), and they do not require the amplitude tapering of the elements for controlling the array radiation pattern.Electrical Engineering, Mathematics and Computer Scienc
