El objetivo del presente estudio es determinar por qué el uso del cuerpo del imputado como fuente de prueba, afecta el debido proceso en el distrito judicial de Cajamarca, 2017 - 2019. Metodología, se utilizó el enfoque cuantitativo y la investigación fue de tipo básica de alcance descriptivo. La población estuvo constituida por jueces del ya mencionado distrito judicial. Mientras que, la muestra estuvo conformada por 20 jueces especializados en materia penal. La selección de ésta se realizó mediante muestreo no probabilístico, aplicando el criterio intencional del investigador. En el recojo de la información se aplicó la técnica de la encuesta y el cuestionario como instrumento. Los resultados demuestran que, el 40% de los magistrados afirmaron que se requiere el consentimiento del imputado para el uso del cuerpo como fuente de información probatoria y el 10% corroboró que, siempre se vulnera el debido proceso. Concluyéndose en caso de que en el cuerpo del imputado existan muestras imprescindibles para brindar eficacia probatoria a la información que abastece la escena del evento delictivo, cuerpo de la víctima o testigos, al estar vedada la dinámica inquisitiva; la intervención corporal se practica ante la actitud estrictamente voluntaria y libre del imputado.

El objetivo del presente estudio es determinar la relación entre la formación profesional de los periodistas y el tratamiento ético de las noticias policiales en los diarios Correo y Satélite de Trujillo. Tras el análisis de las noticias policiales publicadas y de los cursos de especialidad de la escuela de Ciencias de la Comunicación de la Universidad Nacional de Trujillo se encontró que entre ambas variables existe una débil correlación. También se determinó que el 40 % de las noticias policiales publicadas en el diario Correo y Satélite contiene debilidades dentro del aspecto ético, puesto que presentan usos frecuentes de términos sensacionalistas, manipulación de imágenes, exageración de la información, palabras inexactas, entre otros factores catalogados como negativos dentro del tratamiento ético de la producción de noticias. Asimismo, en esta investigación también se encontró que el 73 % de las noticias policiales publicadas en el diario Satélite tienen limitaciones dentro del aspecto ético. En tanto, el mismo problema presenta el 6,7 % de las noticias policiales publicadas la edición regional de Correo – La Libertad.

El objetivo del presente estudio es determinar el desempeño entre la gestión del Gobierno Local y el desarrollo sostenible de la Ciudad de Tarapoto-Perú, periodo 2019 -2021. El trabajo de campo se realizó en sectores y poblaciones que involucran la ciudad de Tarapoto, Provincia y Región de San Martín, República del Perú. De la muestra aplicada con el análisis estadístico de desviación estándar, se ha encuestado a veinte personas por cada sector y población; entre, autoridades locales, profesionales, técnicos ciudadanía en general. Se demostró que hay dependencia entre la variable independiente y dependiente, es decir se concretiza la relación Causa – Efecto. Concluyendo que los conceptos y criterios que se vienen manejando por parte de las autoridades del Gobierno Local no están siendo aplicadas correctamente, para lograr el desarrollo sostenible de la ciudad de Tarapoto.

Here we present the results obtained from the 3D inversion of the full impedance of 21 magnetotelluric soundings in the frequency range of 1000–0.05 Hz. The results confirm the existence of a flat lying conductor at a depth of 2–4 km bmsl under the Colima Volcano (CV) acting as a natural cap seal of the Colima Volcanic Complex hydrothermal system. Model results along five EW vertical sections extracted from the 3D inverted impedance show that the upper crust (<15 km) in the northern sector of the CVC is far more resistive (>1000 ohm·m) and compact than in the southern zone, where it becomes more conductive and apparently more fragmented. The combined results of horizontal and vertical resistivity slices and sections reveals a vertical conductor (10–20 ohm·m) of ellipsoidal shape under the Colima Volcano, which extend from about 5 km bmsl down to at least 15 km bmsl. The approximate dimensions of the major and minor axis of the elliptical conduit along the fault are about 20 km and 5 km respectively. The major axis of the ellipsoidal enhanced conducting pathway is parallel to a NS fault segment off the main NE-SW fault system, which suggests that this fault segment is currently controlling the magmatic fluids ascent. Down to about 15-18 km bmsl the crust becomes widespread conductive, coinciding with a flat body of low shear-wave velocity (<3.2 km/s) under the Colima Volcano at similar depths. This low density and low resistivity flat lying mush reservoir contains H2O-rich melts prone to be polarized electrically and to polarize the surrounding medium. The supporting evidence suggest that the recent and near-future activity of the CV is closely related to a deep flat magmatic source rather than to a shallow magmatic chamber, and that the triggering mechanism of recurrent magmatic activity of the CV may have an electrical component.  

The Volcán de Colima, one of the most active volcanoes in Mexico, has experienced several volcanic crises over the last century with the emplacement of voluminous block-and-ash flow deposits providing large volumes of loose material along the main ravines. During the rainy season, this material is easily eroded forming lahars. Over 40 events with variable magnitude (105-106 m3) have been detected each year. The largest events that cause damages to infrastructure are usually triggered during the hurricane season (from mid-August to October) when more than 250 mm of rain usually are accumulated over a few days. On 23 October 2015, Hurricane Patricia hit the Volcán de Colima. The hurricane was announced as having reached category 5 thereby representing the largest ever recorded hurricane event in Mexico. It rapidly weakened after landfall but followed a straight trajectory toward the volcano. Up to 400 mm of rain were recorded over 30 hours. The event was recorded at a monitoring station located in the middle reaches of the La Lumbre ravine on the SW flank of the volcano, which was equipped with a rain gauge, a geophone (10 Hz), and a video camera. A multi-pulse lahar started around 8 pm (GMT) and lasted for more than five hours. The seismic signal and the video images were analyzed to identify the timing of the main pulses, the sediment concentrations, and maximum flow peak discharge. Data show that the lahar was characterized by three main pulses, in the range of debris flows with maximum flow-depth of 8 m, interspersed by more dilute tails as hyperconcentrated flow, as also observed from the frequency contents of the seismic signal. A total volume of 2.5 × 106 m3 was estimated based on the strong correlation between the seismic amplitude and the flow discharge. The lahar destroyed one bridge and ~500 m of the interstate road leaving several villages cut off for a few days. Based on the flow magnitude, duration, and the associated damage, this event probably represents the largest one recorded over the last 20 years. The FLO-2D model was used to replicate the observed event to estimate the maximum inundation limits of lahars along the five principal ravines of the volcano, in an attempt to design a hazard map for catastrophic hurricane-induced events.

The generation of dilating spaces in the host rocks is essential to facilitate the circulation and accumulation of mineralizing fluids with economic potential. In disseminated deposits, the volumetric and morphological changes in rocks with quartz and feldspar, due to their coefficients of relative differential thermal expansion (contraction), determine dilatancy, making them porous and permeable to fluids. The contrasting thermal expansion constants for quartz and feldspar in thermo-increasing and thermo-decreasing processes are reviewed by volumetric modeling of the effect of a significant variation of the quartz transition α−β around 575 °C. This phenomenon could vary from 0.4 % to 1.2 % for granite with different quartz content during the cooling of a typical porphyry boxwork. In the case of vein bodies, faulting produces dilation by transtensive bending with an increase in thickness when they show irregular, stepped and/or bended shapes. According to Anderson's Law, portions of these faults will be dilatant when the principal stresses are subparallel (γ = the angle between σ1 and the fault surface). The morphostructural and kinematic knowledge of the mechanisms that generate the controlling dilatancy of mineralization constitutes a valuable and practical work methodology that contributes to the location forecast of the best mineralization sectors in terms of volume and quality during prospecting and exploration activities. Both described physical mechanisms that generate dilation in the host rocks are factors of great importance in the economic definition of the mineralizations control.

The fauna provincialism in the interval led to the appearance of some problems with the tracing of this boundary with biostratigraphic methods. Therefore, it is important to determine auxiliary non-biostratigraphic markers of the boundary. The article is focused on the evaluation of the correlation potential of carbon isotope excursions near the Viséan/Serpukhovian boundary, with special attention to the northern Laurussia region. The biostratigraphically constrained carbon isotope record is revealed from the terminal Viséan ‑ lower Serpukhovian (Mississippian) shelf successions of the northern Laurussia (six key sections located in the north of Urals and Cis-Urals, NE Europe). Onset of a negative excursion in the middle part of the Lochriea ziegleri conodont Zone (lower Serpukhovian) shows amplitude of 1–2‰ and high spatial stability, and can be used as a stratigraphic marker in regional and global correlations.

In geology, a fault is a rock fracture with perceptible relative displacement of the opposite sides of the fracture. Quantitatively obtaining the activity history of faults depends mainly on the estimation of fault slip and the study of markers, which can be used to understand and analyze the tectonic evolution of the faulted regions. Fault slip is calculated by restoring points that were originally adjacent before the deformation, those points are named piercing points. In this paper, we review some published methods to determine fault slip, using: (1) the offset of contours on structural contour maps; (2) offset on seismic reflection sections; (3) a known slip vector (fault striae) and one marker; (4) two known markers. Cases (3) and (4) are commonly applied to field work and geological maps.
