DARCY-FORCHHEIMER TANGENT HYPERBOLIC NANOFLUID FLOW THROUGH A VERTICAL CONE WITH NON-UNIFORM HEAT GENERATION
Authors: Khan Husna A. , Nazeer Ghazala , Shehzad Sabir Ali
Published: November 2022

The convective flows through different geometries have numerous applications in high-speed aerodynamics, nuclear cooling systems, fiber technology, and polymer engineering. In the present paper, we investigate the non-linear, mixed convective, boundary-driven, tangent hyperbolic nanofluid flow through a cone. The flow takes place under nonuniform heat sink/source. Darcy-Forchheimer effects have also been taken into account in mathematical modeling and analysis. The Buongiorno model is implemented to examine the effects of thermophoresis and Brownian motion parameters. The governing equations are constructed through the laws of conservation. The modeled flow problem is converted into a set of ordinary differential equations with the help of proposed similarity transformations. To interpret the modified system of equations, the homotopy analysis method (HAM) is applied. The roles of versatile parameters of interest are analyzed and sketched for better understanding. The velocity profile increases by increasing the Darcy number, and converse behavior is found by giving rise to the Forchheimer inertial drag parameter. The rise in temperature profile occurs by increasing a non-uniform heat source variable. The concentration profile enhances when the value of the thermophoresis parameter increases, and shows inverse behavior for the Brownian motion parameter. In the Buongiorno model, nanoparticle concentration has an inverse relation with the Brownian motion parameter. So, the concentration profile declines for greater Brownian motion parameter. To understand the behavior of flow through a cone, the values of Nusselt number and Sherwood numbers are examined.

Salt crystallization is a major cause of damage in porous building materials. Accelerated salt weathering tests carried out in the laboratory are among the most common methods to assess the durability of material to salt decay. However, existing standards and recommendations for salt weathering tests have limitations in terms of effectiveness and/or reliability. In the framework of the RILEM Technical Committee 271-ASC, a procedure has been developed which proposes a new approach to salt crystallization tests. It starts from the consideration that salt damage can be seen as a process developing in two phases: accumulation of the salt in the material and propagation of the decay. In the first phase, salts are introduced in the material and accumulate close to the evaporation surface, while in the second phase damage propagates because of repeated dissolution and crystallization cycles, induced by re-wetting with liquid water and by relative humidity changes. In this paper, the procedure is described and the results of a first round robin validation of the test, carried out on 7 materials and involving 10 laboratories, are presented. The results show that the procedure is effective to cause decay within the time period of the test (about 3 months) and that the decay increases with subsequent cycles. The decay observed differs in type and severity depending on the salt type and concentration and on the type of substrate. The decay types detected in the laboratories are generally representative of those observed in the field for the selected substrates. The differences in durability between the various substrates, as assessed at the end of the test, are in line with the durability expected based on field observation. The reproducibility of the results in terms of decay type is good; some differences have been observed in terms of material loss. These are more significant in the case of NaCl contaminated specimens. Based on the results, proposals for fine-tuning of the procedure are given.
A model of the costs for tidal range power generation schemes
Authors: Vandercruyssen David , Howard David , Aggidis George
Published: November 2022

Tidal range power is gaining recognition as a globally important power source, replacing unsustainable fossil fuels and helping mitigate the climate change emergency. Great Britain is ideally situated to exploit tidal power but currently has no operational schemes. Schemes are large and expensive to construct, assessment of their costs is usually examined under conditions of commercial confidentiality. A national strategy for delivery needs a more open system that allows cost estimates to be compared between schemes; a model that evaluates the capital cost of major components has been developed. In 1983, Massachusetts Institute of Technology published a simple additive model of the costs of tidal range schemes on the east coast of the United States. Their model has been updated and benchmarked against recent schemes with published costs; the Sihwa Lake Tidal Power Station (South Korea, completed in 2011) was used along with the published costs for the Swansea Bay Tidal Lagoon proposal in South Wales to benchmark the model. There are developments in civil and mechanical engineering that may influence both the costs and speed of deployment. These are discussed along with methods for their inclusion into the model.
Between Propaganda and Dissent: Postmodern Architecture in Pinochet’s Chile
Authors: Klein Lidia
Published: November 2022

Postmodern forms and tendencies that appeared in Chilean architecture in the 1970s not only overlapped with Augusto Pinochet’s neoliberal dictatorship that lasted from 1973 to 1990 but also are closely connected to the political and economic vision fostered by the dictatorship. Postmodern forms found in banks, hotels, and other commercial buildings and spaces populating Chilean cities in the seventies and eighties aided the government’s political agenda as they helped to normalize painful neoliberal reforms and create an image of prosperity and progress. Moreover, in projects such as the Plaza de la Constitución in Santiago de Chile (1980–1982) and the Congreso Nacional de Chile in Valparaíso (1988–1990), postmodern aesthetics and philosophy were used to project an image of an open democratic country. In these realizations, postmodern tropes such as the symbolic potential of architectural form and references to architectural tradition were used to fabricate a vision of history and society desired by the Pinochet government. Simultaneously, the same architectural currents embraced by Pinochet for propagandistic purposes were utilized by Chilean architects who considered themselves opposed to the dictatorship. This can be seen in the work of CEDLA (Centro de Estudios de la Arquitectura, Center for Architectural Studies), an independent collective of Chilean architects established in 1977 in Santiago de Chile. The members of CEDLA promoted a version of a politically and socially engaged postmodernism that could counter the neoliberal agenda of Pinochet. This paper discusses both ways in which postmodernism was interpreted in Chile during the dictatorship. Investigating Chilean postmodernism helps us rethink the dominant portrayal of postmodernism as politically indifferent or conservative and as part of Jameson’s ‘cultural logic of late capitalism’.
Soy un amasamiento. Political Collectivity and the Problem of Identity
Authors: Martinez Mateo Marina
Published: November 2022

"Identity" is an important political category to highlight and confront experiences of discrimination, exclusion, or oppression that remain invisible within anabstract reference to equality. However, as a point of reference, "identity" produces ambiguities and exclusions that seem to challenge the possibility of building political collectivities and establishing practices of speaking for each other. In the first two parts of this article, I will develop the problem of identity for the formation of collectives. On this ground, I will argue that instead of leading to further fragmentation and individualization, this insight could be a starting point to think about the relationship between identity and political subjectivity in different ways. This will be discussed in the third step, drawing primarily on Chicana Feminism (especially Gloria Anzaldúa and Chela Sandoval) where the aim of building political collectivities that surpass the notion of identity assumptions is derived from an ethical-aesthetic idea of transformation and alienation that I will suggest to understand with Anzaldúa's term "amasamiento."
Factors that may impair the walkability of students on the route between the Alencastro urban public transport station and the Federal Institute of Mato Grosso (Cuiabá Campus)
Authors: Souza Yanne Emelyn da Silva , Magagnin Renata Cardoso
Published: November 2022

Currently, a large number of people move around cities on foot. But few municipalities have a detailed diagnosis of this infrastructure quality, especially around school areas. Given this reality, this article aims to present the results of a study that evaluated the factors that affect the walkability of students on the route between the Alencastro Urban Public Transportation Station to the Federal Institute of Mato Grosso (Cuiabá Campus). The methodology consisted of applying the walkability index (ICam) developed by the Institute for Transportation and Development Policies (ITDP Brazil) in 2018, which allows the following themes to be evaluated: sidewalk, mobility, attractiveness, public safety, road safety, and environment. The results show that the evaluated path needs some priority interventions related mainly to the themes Public Safety and Attractiveness, with short-term actions that should be implemented by the local public authorities. And the results show that the methodology used is easy to use and thus can contribute to the development of similar studies.
Perrotta Autism Spectrum Disorders Questionnaire for infants and young adolescents (PASD-Qy)
Authors: Giulio Perrotta
Published: November 2022

Building on the concept of “Autism Spectrum Disorder”, as framed in the DSM-V, and taking up studies on the new etiological theory (PETA) focusing on the developmental model of the neurobiological matrix (PEMA) and related questionnaire (PTAS-Qa), in this research a new questionnaire is proposed that can focus on the presence or absence of 4 functional areas (interactional and movement, language, and communication, ideational and social, emotional and behavioral) and 25 type-deficit traits, grading the impairment according to a precise 5-level severity scale (PASSy). The new questionnaire (Perrotta Autism Spectrum Disorders Questionnaire for infants and young adolescents, PASD-Qy), is composed of 25 items, on a binary S/N scale and based on a total score of 10/10, for a population between 18 months and < 16 years, thus offering a structured view of the individual’s cognitive organization, avoiding diagnostic fragmentations that might be inconsistent with the nosographic framework. By exemplifying the category, it is then possible to more easily frame the patient, who would thus be analyzed from a strictly functional point of view, also facilitating the preparation of therapeutic interventions, according to models already known in the literature (e.g., ABA), exactly as for the questionnaire dedicated to late adolescents and adults.
Chickpea breeding program and research in portugal
Authors: Isabel Duarte
Published: November 2022

Chickpea (Cicer arietinum L.) is a very important crop in the world. Portugal was traditionally sown as a spring crop and so extremely affected by long periods of drought and temperature variation throughout the growth cycle. Chickpea grain yields decrease substantially due to increased air temperature and the severity of drought. To face the Mediterranean-type climate pattern, chickpea breeding programs were reoriented to develop chickpea germplasm tolerant/resistant to the main abiotic and biotic stress and adapted to different environments and production systems. This study relates chickpea yields (35 years) with rainfall average in Alentejo, a Southern Portugal region with a Mediterranean-type climate. Our approach shows that selection should apply multiple and complementary criteria. The physiological and morphological studies are important in breeding programs, to combine not only resistance to drought and temperature, and biotic stress but also high yield potential and yield stability. The main objective is to obtain new chickpea varieties for the rainfed conditions of the Mediterranean region. From this work, four chickpea varieties (Kabuli type), were registered on the National Variety Catalogue. Actually, the national chickpea genetic breeding program has already registered 11 varieties.

Authors: Eyong Clinton Achere , Adamu Ndongho Ndifontiayong , Fokunang Charles Ntungwen , Nsagha Dickson Shey
Published: November 2022

Background: Malaria parasitemia and HIV infections are globally important public health concerns. People residing in regions where these two infections are endemic are prone to develop co-infection. Sub-Saharan Africa has the greatest burden of both diseases and Cameroon particularly the South West Region has been reported as one of the regions with the highest malaria and HIV prevalence. Hence, there is a need for continuous monitoring and epidemiologic inquiry to generate updated data on the burden of malaria parasitemia on HIV/AIDS. The aim of this study was to determine the prevalence of malaria parasitemia and the association between viral load and malaria parasite density in people living with HIV/AIDS in Kumba, Cameroon. Methods: A cross-sectional study was conducted involving 250 people living with HIV/AIDS selected from five main Community Based Organizations in Kumba during a period of 5 months from April to August 2021. Participants’ consent was obtained followed by socio-demographic and other useful data via a standardized questionnaire. Capillary blood samples were collected and Giemsa-stained blood films were examined to detect malaria parasitemia. The recent viral loads were collected from the participants’ medical files. Pearson’s chi-square was used for the comparison of proportions and correlation analysis to determine the association between parasite density and viral load. Statistical significance was set at p < 0.05. Results: An overall prevalence of malaria parasitemia in people living with HIV/AIDS in Kumba was 27.2%; [95% CI: 21.8% – 33.2%]. Among 215 participants who were HAART-experienced, 49(22.79%); [95% CI: 17.6% – 27.9%] were found to be positive for malaria parasitemia while 19(54.29%); [95% CI: 48.1% – 60.5%] out of the 35 HAART naïve individuals were positive for malaria parasitemia. This difference in prevalence was statistically significant (X2 = 15.078, df = 1, N = 250, p < 0.000). Also, malaria parasite density was significantly dependent on viral load (X2 = 61.065, df = 6, N = 49, p < 0.000). HAART-experienced participants with high viral load(>1000copies/ml) had significantly higher malaria parasite density(>400trophozoites/µL) than HAART-experienced participants with ‘not detectable’ viral load. Conclusion: The prevalence of malaria parasitemia in the study population was 27.2%. HAART naïve individuals had significantly higher malaria parasitemia prevalence and malaria parasite density than HAART-experienced individuals. Malaria parasite density was significantly dependent on viral load in HAART-experienced individuals.

Uno de los retos a los que se enfrentan las organizaciones deportivas radica en garantizar la fidelización del talento humano. Para ello se han propiciado estrategias de compensación como el salario emocional: una práctica extrasalarial que contempla las expectativas intangibles y las necesidades de bienestar e integridad de los colaboradores. El objetivo del presente estudio fue identificar qué componentes del salario emocional tienen incidencia en la fidelización laboral del futuro administrador deportivo según su expectativa profesional. El tipo de estudio es cuantitativo con carácter correlacional-causal. Se aplicó un instrumento a estudiantes del programa profesional de Administración Deportiva en la Universidad Distrital Francisco José de Caldas de Bogotá (Colombia). Se evaluaron dos componentes: expectativa profesional y salario emocional. Se encontró que los criterios de fidelización laboral del futuro administrador deportivo se fundamentan en aspectos del salario emocional como el apoyo para la formación profesional y la capacitación constante; en cuanto a la expectativa profesional esperan alcanzar un alto nivel académico formal (maestría o doctorado) con una vinculación laboral preferiblemente a término indefinido.
Digital Rights, Institutionalised Youths, and Contexts of Inequalities
Authors: Brites Maria José , Castro Teresa Sofia
Published: November 2022

In this article, we aim to discuss digital rights and media literacy in the context of socio-digital inequalities experienced by institutionalised youths. In the case of these digitally disconnected youths in detention centres, there is evidence of multiple life-course disadvantages that will resonate throughout their future lives. They see their present and future lives deeply challenged by the fast pace of technological innovation and its social impacts while living in environments that we see as digital deserts. The data we bring to the discussion results from the Portuguese participatory project DiCi-Educa. We worked for three years with institutionalised youth on digital media production and critical thinking regarding digital citizenship, participation, and otherness issues. This article is organised around two research questions: What were youths’ practices regarding media and digital environments before institutionalisation? How did they discuss these digital environments and their digital rights during the project? Early findings point to (a) the importance of implementing critical methods to help them to think about technologies in diverse daily life contexts, (b) the need to provide venues for institutionalised youth to build critical thinking and communication skills, and (c) the necessity to widen their worldviews and promote positive behaviours.

The history of the study of swamps and wetlands in Galicia and Lviv region is considered. Centers of peat development in the studied region were identified. Peculiarities of swamps distribution within the plain part of Lviv region and Male Polissia were studied. Malopolissia swamps occupy 59.6 % of the total area of swamps in the plains of Lviv region. The location of the swamps is related with the wetlands of the Western Bug and Styr valleys. The region is dominated by lowland swamps with a predominance of grass groups, less common grass-moss, shrub and forest groups. Within Male Polissia, 57 peat deposits with a total area of 27.76 thousand hectares have been registered. The balance mineral reserves of peat amount to 83,339 thousand tons. The largest peatlands in terms of area and balance mineral reserves are Stoіaniv, Solokiia, Leshniv, Lviv, Smilne and Radekhiv. On the basis of topographic maps the tendencies of change of areas of swamps and wetlands in the interfluves of the Western Bug and Rata for the last 240 years are analyzed. The general trends towards the reduction of wetland areas have been noted. The process of reducing the area of swamps changed in different historical periods. Before the construction of the main canalized channel of the Western Bug, the straightening of riverbeds of Rata and Solokia, and drainage works on small rivers and streams, the level of wetlands remained high and ranged from 14.6 to 23.1%. After the channel straightening and drainage works were completed, the share of wetlands fell to 7.8% of the total area. In the past, the peatlands of Male Polissia were a valuable industrial resource: chemical raw materials, fertilizer for agriculture, fuel for household needs, and a medicinal natural resource in medicine. The primary functions of peatlands are the storage of dampness and biological diversity, and importantly, carbon dioxide. Swamps and peatlands are the most efficient ecosystems for carbon storage. Topical issues of geoecological significance of wetlands of the studied region are considered, in particular, they act as hydrological and climatic regulators, centers of greenhouse gas deposition, distribution areas of valuable and rare plant species, etc.

Mediation, Remediation, and Commercialization of Indonesian Identity in Sneakers Advertising
Authors: Sari Dewi Kartika
Published: November 2022

The utilization of Indonesian national identity in fashion products, notably shoes, inspired this research. Retail goods that exhibited an Indonesian identity offered producers a chance to draw in sneakers fans. This research aimed to discuss the mediatization of Indonesian national identity. The three Instagram accounts @exodos57, @bro.do, and @sepatucompass were selected as the study’s subjects. Young Indonesians are currently enamored of sneakers from these brands. Many young individuals also follow their Instagram accounts. The data was to be analyzed using mediation, remediation theory, and commercialization. To investigate the data, a qualitative technique using explanatory research was used. The findings demonstrated that mediation, remediation, and commercialization are three processes that engage with one another. Additionally, it is possible to interpret the utilization of national identity as a response to globalization and the quest for authenticity. The logic of commercialization might be applied to this legitimate research.

Authors: El-Sayed Samir Mohamed , Tappozada Tarek Mokhtar , Mansour Fahd Mohamed , Ali Eman Sheta
Published: November 2022

Background: Chronic endometritis (CE) is a cause of recurrent implantation failure (RIF) in patients undergoing intracytoplasmic sperm injection (ICSI). CE is diagnosed based on the presence of plasma cell infiltration of the endometrial stroma in endometrial biopsies. Hysteroscopy may be suggestive of CE while the immunohistochemistry with specific cell markers for CD138 cells has been suggested as a more accurate test for the diagnosis of CE.Methods: This study included 110 patients with recurrent ICSI failure (two or more), despite using good-quality embryos. Hysteroscopy and endometrial biopsy were performed as an outpatient procedure. Immunostaining was then performed using a mouse monoclonal CD138 antibody. The prevalence rate of CE was calculated, and the correlation between hysteroscopic findings and immunohistochemical results was assessed. Results: In the included patients in this study there was 32 cases (29%) were diagnosed as CE by hysteroscopy, while 27 cases (24.5%) were positive by CD138 immunohistochemistry (IHC), and 18 cases (16.36%) were positive for CD138 IHC with hysteroscopic features of CE. The presence of more than one abnormal hysteroscopic features was considered positive for CE rather than single abnormal feature, the sensitivity, specificity, positive and negative predictive values of hysteroscopy would be 22.2%, 98.8%, 85.7%, and 79.6%, respectively.Conclusions: The negative diagnostic value of hysteroscopy is high, the combination of the two diagnostic modalities (hysteroscopy and CD138 IHC) will aid in the detection of most cases of CE.

Authors: Khokhrin S. A.
Published: November 2022

This article is the result of a comprehensive study of the crisis situation, its concepts and types in relation to the penal system. The relevance of the article is due to the fact that the institutions of the penal enforcement system actively use a large amount of diverse conceptual apparatus associated with the introduction of a regime of special conditions in the event of natural, man-made or criminal situations, which significantly complicates the possibility of assessing the onset of negative consequences from their occurrence and the need to attract additional forces and funds of federal executive authorities. The purpose of the publication is to define the concept of crisis situations in relation to the penal system based on the analysis of the conceptual apparatus used in penitentiary institutions for the prevention and overcoming of crisis situations. The article uses such general scientific research methods as generalization, analysis and synthesis, concretization. As a result of the analysis of the legislative framework and the opinions of scientists, the main types of crisis situations of a criminal, natural or man-made nature have been identified. The author believes that the legislative consolidation of the concept of a crisis situation will improve the legislative framework and regulate issues of interaction between the Federal Penitentiary Service of Russia and other federal executive authorities in these situations.

Published: November 2022

The article examines the importance of the institution of legal encouragement in improving the effectiveness of criminal procedural activities as an effective legal instrument. Analyzing the essence of efficiency in criminal proceedings, the author notes that the interest of society and the individual stems from social needs based on basic values, including those transmitted by the state. One of the value orientations can be considered the request of society for the effective implementation by the state of its public administrative function, ensuring the protection of the rights and freedoms of every citizen involved in criminal proceedings. The author comes to the conclusion that each of the participants in the criminal procedural relations has its own need arising from the legitimate interest provided for by the criminal procedural legislation. In this case, the institution of legal encouragement is one of the universal ways to achieve mutual benefit and efficiency of criminal procedural activities.

Published: November 2022

Objective: Dental educational curricula are under constant modification and improvement. However, designing a comprehensive, efficient, and flexible curriculum is still challenging for the authorities. An efficient curriculum should obviate the educational needs of students and promote their knowledge and expertise for future practice. Time planning of clinical rotations is highly important for optimization of the learning process. This study aimed to compare the efficacy of two different timing models of clinical rotations, namely four versus two rotations in each semester.
Materials and Methods: A total of 74 dental students and 54 faculty members of Tehran University of Medical Science that experienced both rotation models for two consecutive years (2018 and 2019) participated in this study. A questionnaire was designed to assess different aspects of the two timing-models.
Results: A one-sample t-test indicated that students' and faculty members' mean perception were significantly better regarding the two-rotation program.
Conclusion: This study indicated that changing the time planning of educational rotations can affect different aspects of education.

En el estado de Tabasco se ha incrementado la población ovina y el número de rebaños en los últimos 10 años. En este escenario, resulta necesario divulgar información técnica que permita, tanto al ovinocultor como al técnico pecuario, incrementar y/o sostener la productividad de las ovejas que conforman un rebaño. La productividad de la oveja se inicia con el primer parto de la oveja y culmina con la muerte o cuando la hembra es eliminada del rebaño. Por ello, resulta importante iniciar el ciclo productivo con primalas cuyas madres hayan desarrollado habilidad materna, es decir, ovejas que han sido capaces de criar y destetar a los corderos que nacieron vivos. En este trabajo se indican las bases que permiten seleccionar a las corderas que conformaran el grupo de hembras reproductoras.

Published: November 2022

La determinación de las tasas de cambio en relación al uso de suelo en el Estado de Tabasco entre los años 1976 y 2000, ha mostrado un deterioro en los ecosistemas naturales, poniendo de manifiesto la necesidad de atender aquellos geosistemas que por su naturaleza y su ubicación geográfica, presentan una mayor fragilidad ante los impactos causados por los seres humanos. Se observó que la formación natural más afectada fue la selva, la cual ha perdido en un lapso de tiempo de 24 años, hasta un 50% de lo que mostraba al inicio de ese periodo. En el presente documento se expone una metodología para la determinación cartográfica de los posibles escenarios que en términos cartográficos para los cambios en el uso del suelo, se pueden presentar en el Estado.
PRODUCCIÓN DE INSULINA A PARTIR DE ORGANISMOS BACTERIANOS: REVISIÓN BIBLIOGRÁFICA PARA LA TÉCNICA MOLECULAR

La diabetes millitus es una de las enfermedades con mayor impacto en la sociedad. Esta problemática provoca que las personas presenten la glucosa elevada en la sangre (hiperglucemia) y otras alteraciones que cambian el metabolismo. Las enzimas de restricción se utilizan para cortar de manera abierta un plásmido, por lo que la misma enzima se utiliza para cortar el gen deseado fuera del cromosoma; esta reacción hace dos cortes que emparejan y cuando se combina el gen y el plásmido forman un enlace temporal. Otra enzima denominada ADN ligasa se utiliza para crear un sello permanente. De esta manera se induce a las bacterias que tomen los plásmidos mientras que estas mismas se desarrollan y se multiplican en el medio, generando la insulina de manera natural a partir de bacterias.

Cuando se trabaja en sistemas acuícolas es común tener problemas de sobrepoblación de crías en los estanques de cultivo (Paramo-Delgadillo, 1985). Aunado a este problema, se han identificado que en algunas especies de cultivo existen diferencias sustanciales en las tasas de crecimiento entre sexos. Para ello, se han generado diversos métodos que han permitido reducir considerablemente estos problemas.

Published: November 2022

Con el objeto de evaluar la composición, abundancia y estructura de las comunidades de moluscos bentónicos de la Reserva de la Biosfera Pantanos de Centla, se realizó un muestreo en 19 lagunas durante el 2004 y 2005 en las épocas de estiaje (abril y mayo) y lluvias (octubre y noviembre). En cada laguna se tomaron diez muestras de sedimento. Se calculó la abundancia, riqueza específica, diversidad de Shannon-Wiener (H´) y similitud de Morisita – Horn. Durante este estudio se recolecto un total de 38,344 moluscos bentónicos, 8,597 en E2004, 14,093 en LL2004, 8,279 en E2005 y 7,375 en LL2005. La clase Bivalva fue la más diversa con ocho especies siguiéndole la Gastropoda con tres, sin embargo los gasterópodos presentaron la mayor abundancia total de la comunidad, siendo C. franceasa (75.25%) y M. tuberculata (23.44%) las más abundantes. Las localidades que presentaron las máximas abundancias totales fueron Loncho, San Isidro y Guanal y no se encontraron diferencias entre las abundancias de estiaje y lluvias. La riqueza específica fue muy homogénea en 15 de las 19 localidades esta varió de ocho a diez especies. Cometa, Coco, Punteada y Narváez fueron las localidades que presentaron baja riqueza. La RBPC se puede caracterizar por ser un área de baja a mediana diversidad de moluscos bentónicos. Existe una alta similitud entre las lagunas estudiadas con excepción de Coco y Cometa.

Se efectuó un bioensayo en larvas del "Atractosteus tropicus", para lo cual se seleccionaron un total de 1,054 individuos con un peso y longitud inicial de (0.08±0.01 g y 26.0±3.0 mm respectivamente) aplicando un diseño bifactorial, donde el primer factor fueron los dos tipos de aceites; vegetal (Patrona, Edo. Mex) y sardina, el segundo factor fueron los dos niveles de lípidos 10 y 15%, más la dieta control comercial para trucha, (Silver Cup®) con 45% de proteína y 16% de lípidos, evaluados por triplicado con una duración de 28 días. Los resultados mostraron que las larvas alimentadas con la dieta (SOL10%) y aceite de pescado con 15% de lípidos (SOL15%), fueron estadísticamente diferentes entre sí y las que mejores pesos y longitudes totales obtuvieron (3.76±0.55 g y 12.13±1.25 mm; 1.46±0.37 g; 7.31±0.67mm) contra las larvas alimentadas con las dietas de control y aceites vegetales (CDPL16%, VOL10% y VOL15% de lípidos). Por lo que se concluye que en la alimentación de las larvas de "A. tropicus" se debe usar aceite de sardina, aunque la utilización de aceites vegetales es posible, no obstante probablemente en menor cantidad.

Salir de compras por ésa prenda o por aquél accesorio que tanto deseamos es algo que a todos nos gusta porque nos relaja y nos llena de satisfacción. Ir al super a surtir la despensa quizás no sea algo que a todos nos guste pero es una actividad que muchos debemos realizar; y es casi seguro que cuando se va de compras nadie va con la idea de adquirir algún kilo de basura porque no es la intención, pero desafortunadamente esa es la realidad, ya que en todo lo que compramos se encuentran bolsas de plástico, papel, cartón, moños de regalos, envases de plástico y de vidrio, latas, entre otras tantas cosas, lo que quiere decir que cada uno de nosotros diariamente producimos una gran cantidad de basura y lo peor no es sólo eso, sino que no sabemos qué hacer con ella, y ya que somos generadores de residuos, debemos ser responsables y contribuir a que esto disminuya. La pregunta ¿cómo lo vamos a lograr?, aprendiendo a manejarlos adecuadamente.
