Biological dosimetry consists of estimating absorbed doses for people exposed to radiation by mean biological methods. Several indicators used are based in haemathological, biochemical, and cytogenetic data, although nowadays without doubt, the cytogeneti...

A revision of physical models of thermally stimulated luminescence (TSL) in crystals induced by both ionizing and non-ionizing radiation is presented. Particular emphasis is given to the connection of TSL with other thermally stimulated processes and phys...

The electron impact excitation followed by fluorescence induced by N(sub 2)-laser absorption was used to study the lifetime of the lowest vibrational level of the B (sup 3)(pi)(sub g) electronic state of N(sub 2). The experimental result of this work is 1...

The effect of chlorophyllin on gamma radiation induced Sister chromatid exchanges (SCE) and on the mitotic index (IM) and average generation time was determined. Groups of mice were treated in one of the following regimens: (1) untreated, (2) treated with...

Una de las principales aplicaciones actuales de los procesos de disociaci�n multifot�nica inducidos por radiaci�n l�ser infrarroja (DMI) es la producci�n de radiales libres, con el fin de estudiar sus propiedades cin�ticas y espectrosc�picas. La disociaci�n de mol�culas poliat�micas en el IR con l�seres de CO2 tiene lugar desde la superficie de energ�a molecular mas baja y ...

The sterile insect technique (SIT) is an environment-friendly pest control technique with application in the area-wide integrated control of key pests, including the suppression or elimination of introduced populations and the exclusion of new introductions. Reproductive sterility is normally induced by ionizing radiation, a convenient and consistent method that maintains a reasonable degree of ...

We evaluated under semi-natural field cage conditions sexual compatibility and competitiveness of a laboratory strain (LAB) compared to a wild population (TUC) of Anastrepha fraterculus (Wiedemann). The LAB strain is produced under semi-mass rearing conditions at the Estacion Experimental Agroindustrial Obispo Colombres facility (Tucuman, Argentina). Wild flies were obtained at Horco Molle ...

Abstract Objective: The full benefit of bilateral cochlear implants may depend on the unilateral performance with each device, the speech materials, processing ability of the user, and/or the listening environment. In this study, bilateral and unilateral speech performances were evaluated in terms of recognition of phonemes and sentences presented in quiet or in noise. Design: Speech recognition ...

The mass-reared colony of Anastrepha ludens (Loew) currently used in Mexico for suppression of the Mexican fruit fly has been in use for over 10 years. Sterile flies are released into a wide range of environmental conditions as part of an integrated area-wide approach to suppress diverse populations of this pest in the Mexican Republic. This paper assesses the performance of the sterile flies ...

Abstract Objective: To investigate word recognition in noise in subjects treated in childhood with chemotherapy, study benefits of open-fitting hearing-aids for word recognition, and investigate whether self-reported hearing-handicap corresponded to subjects' word recognition ability. Design: Subjects diagnosed with cancer and treated with platinum-based chemotherapy in childhood underwent ...

Abstract Objective: Audiological data from a population based epidemiological investigation were studied on elderly persons. Specific diagnoses of otological and audiological disorders, which can result in hearing loss, were searched for. Design: A retrospective register study. Study sample: Three age cohorts, 474 70- and 75-year olds ("younger"), and 252 85-year olds ("older"), were studied. ...

Geophysical and hydrochemical borehole-logging techniques were integrated to characterize hydraulic and hydrogeochemical properties of the Chalk aquifer at boreholes in Berkshire, UK. The down-hole measurements were made to locate fissures in the chalk, their spatial extent between boreholes, and to determine the groundwater chemical quality of the water-bearing layers. The geophysical borehole ...

Water outbursts from the floor during underground mining, and those from the surrounding rock mass of tunnels, involve the basic principle of hydraulic fracturing. Based on the hydraulic-fracturing mechanism, considered to be dependent on the coupling between seepage and damage, it is deemed that the variation of the pore-fluid pressure coefficient must be taken into account during this coupled ...
