Incidencia del polen de Plantago en la atmósfera de Málaga y su relación con los parámetros meteorológicos
Authors: Recio Marta , Trigo M. Mar , Toro F. Javier , Cabezudo Baltasar
Published: April 2020

En el presente trabajo se exponen los resultados obtenidos para el polen de Plantago tras el muestreo realizado durante los últimos años en la atmósfera de Málaga. Dicho muestreo se ha llevado a cabo mediante un captador volumétrico de tipo Hirst, habiéndose analizado las variaciones anuales, estacionales e intradiurnas, así como su relación con los principales parámetros meteorológicos. Las mayores concentraciones se han registrado siempre durante los meses de Abril y Mayo, y entre las 12 y 14 horas locales, habiéndose observado diferencias cuantitativas importantes en los años 1995 y 1996, debidas fundamentalmente a la desigual cantidad de precipitaciones acumuladas durante los meses anteriores al período de polinación. Las correlaciones obtenidas entre los valores diarios de concentración atmosférica de polen y los de los diferentes parámetros meteorológicos demuestran que, en Málaga, este polen se asocia positivamente siempre con la insolación y la temperatura durante el período prepico, con las precipitaciones durante el período postpico y, casi siempre, con la velocidad y dirección noroeste del viento.

Authors: Ata Enes , Kıymaz İ. Onur
Published: April 2020

In this study, motivated by the frequent use of Fox-Wright function in the theory of special functions, we first introduced new generalizations of gamma and beta functions with the help of Fox-Wright function. Then by using these functions, we defined generalized Gauss hypergeometric function and generalized confluent hypergeometric function. For all the generalized functions we have defined, we obtained their integral representations, summation formulas, transformation formulas, derivative formulas and difference formulas. Also, we calculated the Mellin transformations of these functions.

Construction of the bridge generally and especially the bridge girders made of steel, wood and concrete materials. The ferrocement technology is not as popular yet as reinforced concrete. In fact, this technology is more economical and can be applied to various things. Now ferrocement technology has been applied in various types and structures in various parts of the country. The use of lightweight concrete in earthquake prone areas is a good alternative, this is because the lightweight concrete can reduce the risk that will be caused by the earthquake. The purpose of this study was to determine the strength of the cross section of the ferrofoam concrete channel beam profile with the addition of pozzolan to the variation of the number of bolt connectors on the profile wing. Then the profile with variation of number of bolts ie: 2 bolts (2 specimens) and 4 bolts (2 specimens) 1 each (test specimen) using a join plate on the side of the body and 1 (specimen) not wearing a joint plate on the body. While the test object that uses 6 bolts (1 specimen) is treated without using the body connector plate. Concrete is planned to have compressive strength (f'c) 35 MPa and steel used is D8 threaded iron. The results of the study were 450.6 larger capacity 103% compared to the 450.2A profile. Unlike the case with the 450.4A profile after receiving the maximum load the load slowly drops until the test is stopped, capacity 450.4A is 89% greater than the 450.2A profile.

The problem is from the increasing number of road contractor companies in Aceh Province, it has not been followed by an increase in qualification and performance. These improvements can be seen from the quality of work, the timeliness of completion of implementation, and the efficiency of resource utilization of personnel, capital, and technology. This study aims to analyze the relationship and influence between contractor's qualification factors on the quality of road construction project, and to know the dominant factor in contractor company's qualification affecting the quality of road construction project in Banda Aceh City. This study used qualitative and quantitative methods through questionnaires, where the respondents were addressed to 90 road contractor companies. The contractor company has implemented projects from 2010-2016, with funding sources from APBA. The independent variables reviewed are contractor qualification factors consisting of legal factors, technical factors, and administrative factors, while the dependent variable is the quality of road construction projects. The results show that the legal, technical and administrative factors all have a very high relationship to the quality of road construction projects in Banda Aceh City. The contractor's qualifying factors all have a significant effect on the quality of road construction projects in Kota Banda Aceh of 91.6%. The dominant factor in the qualification of contractor companies affecting the quality of road construction projects in Banda Aceh is the technical factor.

Published: April 2020

Nagan Raya District Government undertook the construction of roads, including the Poros Utama Road of Kuala Subdistrict. At the time of rain, in certain locations are still formed puddles above the surface of the asphalt. Therefore, it is necessary to evaluate the efficiency and duration of draining flow through the inlet on the road. The data required are the type, distance and dimensions of the existing inlet and the location map, the maximum daily annual rainfall data, cross and longitudinal sectional drawing. Calculations start by calculating the design flow of rainfall data processing. Furthermore, the calculation of the gutter flow as well as the efficiency and the inlet draining time. Based on calculations, the efficiency of the existing inlet in the form of a curb opening inlet is in the range between 4,93% to 6,51% with  0,64-3,92 minutes of draining time. This value indicates that the inlet on the road produces very low efficiency. Inlet is expected to drain all the water or 100% efficiency. The inundation disturbs the movement of the vehicle and affects the pavement resistance. Therefore, the flow of water above the road surface is expected not to create a puddle.

Published: April 2020

A Criptosporidiose é uma zoonose parasitária de distribuição cosmopolita. O Cryptosporidium spp., agente etiológico da doença, tem localização intracelular, completa seu ciclo biológico na superfície de células epiteliais dos tratos respiratório e gastrointestinal e são responsáveis pela síndrome da “diarreia aquosa”, acarretando em desidratação, perda de peso, retardo no crescimento e morte dos indivíduos infectados. A Criptosporidiose ocorre com maior gravidade em animais neonatos e/ou imunocomprometidos, causando grandes prejuízos econômicos. Os protozoários do gênero Cryptosporidium spp., apresentam ciclo de vida monoxeno, ou seja, o realizam em um único hospedeiro. Em caprinos jovens, menores de 30 dias de vida, o sinal clínico habitualmente observado é o de diarreia severa, que pode durar de 5 a 20 dias comprometendo o crescimento destes indivíduos e podendo levá-los à óbito. O diagnóstico da Criptosporidiose em caprinos pode ser realizado com o uso de técnicas de coloração em esfregaço fecal e Centrífugo-flutuação, de fácil execução e baixo custo, ou ainda por técnicas mais modernas e precisas como a PCR. Pelo conteúdo exposto nesta revisão, é possível concluir que apesar da Criptosporidiose ser uma enfermidade crônica e ainda não ter tratamento efetivo para o combate do seu agente etiológico, tem na prevenção a principal forma de evitar a disseminação da doença no rebanho caprino.
