In the Peruvian Amazon, we conducted an extensive survey of bird species in six secondary forests. We used the point count method and established 360 survey points (60 in each zone) at least 500 meters away from the others. These observations covered six zones across nine departments, including Loreto, Amazonas, San Martín, Ucayali, Huánuco, Pasco, Junín, Cusco, and Puno, at altitudes ranging from 96 to 2501 meters. We assessed these forests in both dry and rainy seasons with two consecutive days of observations at each point. Our findings revealed high species richness in every zone, with a total of 628 bird species identified, including one Endangered, and five Vulnerable according to the IUCN. Passeriformes was the order with the most species registered, while Tyrannidae and Thraupidae were the most species-rich families. Zones within protected areas exhibited higher species richne...

Seismo-volcano source localization is essential to improve our understanding of eruptive dynamics and of magmatic systems. The lack of clear seismic wave phases prohibits the use of classical location methods. Seismic antennas composed of one-component (1C) seismometers provide a good estimate of the backazimuth of the wavefield. The depth estimation, on the other hand, is difficult or impossible to determine. As in classical seismology, the use of three-component (3C) seismometers is now common in volcano studies. To determine the source location parameters (backazimuth and depth), we extend the 1C seismic antenna approach to 3Cs. This paper discusses a high-resolution location method using a 3C array survey (3C-MUSIC algorithm) with data from two seismic antennas installed on an andesitic volcano in Peru (Ubinas volcano). One of the main scientific questions related to the eruptive pro...

Formation of broad plasma depletions (BPDs) at night in the equatorial F region is understood in association with plasma bubbles. However, we report BPDs that do not show a connection with bubbles. The characteristics of BPDs are investigated using the observations of the Communication/Navigation Outage Forecasting System (C/NOFS) satellite on 31 December 2008, 28 July 2010, and 1 February 2011. On those days, BPDs are detected in the longitude regions where C/NOFS did not detect bubbles prior to the detection of BPDs. The coincident C/NOFS and radar observations over Jicamarca in Peru show the occurrence of BPDs at the time when backscatter echoes are absent and at the height below backscatter echoes. These observations indicate that bubbles are not a prerequisite for those BPDs. The detections of those BPDs can be explained by the uplift of the equatorial F region peak height above the...

We investigated the association of broad plasma depletions (BPDs) with plasma bubbles and ionospheric uplift in the equatorial F region using the coincident satellite and radar observations over Jicamarca in Peru. BPDs were detected by the first Republic of China satellite (ROCSAT-1) on the nights of 21 and 22 December 2002 during the period of moderate geomagnetic activity. The observations of the Jicamarca Unattended Long-term Investigations of the Ionosphere and Atmosphere radar and an ionosonde showed that the F peak height was lifted above the ROCSAT-1 altitude (600 km) at the times of the BPD detection. The fraction of NO+ was substantial at the locations of BPDs. These observations support the association of the BPDs with the ionospheric uplift. However, the absence of large backscatter plumes at the times of the BPD detection indicates that the BPDs were not produced by a single ...

The rising global demand for food, including potatoes, necessitates increased crop production. To achieve higher yields, farmers frequently depend on regular applications of nitrogen and phosphate fertilizers. As people seek more environmentally friendly alternatives, biofertilizers are gaining popularity as a potential replacement for synthetic fertilizers. This study aimed to determine how Glomus iranicum affects the growth of potatoes (Solanum tuberosum L.) and the nutritional value of potato tubers when grown alongside broad beans (Vicia faba L.). An experiment was conducted using potatoes tested at five dosage levels of G. iranicum, ranging from 0 to 4 g, to see its impact on the plants and soil. Inoculation with G. iranicum produced variable results in associated potato and bean crops, with significant effects on some variables. In particular, inoculation with 3 g of G. iranicum pr...

La Botritis, más conocida como mancha chocolate, es una enfermedad, causada por un hongo, llamado Botritis fabae, que ataca a las plantas de haba. Es la principal enfermedad que afecta al cultivo de haba en las hojas, tallos, flores, vainas y granos. Este hongo se desarrolla con la humedad, ataca al cultivo desde la emergencia hasta la madurez. El exceso de población de plantas, poco distanciado entre ellas, lluvias abundantes y suelos arcillosos con inundación de un terreno, favorece la aparición de esta enfermedad.

La investigación plantea el objetivo de analizar la problemática suscitada en la contratación en el Instituto Nacional Materno Perinatal (INMP), reconocer el origen de sus características según la información recolectada, para luego sugerir soluciones según perspectivas de amplitud que contribuya a los servidores del órgano encargado de las contrataciones de esta institución, adecuarlas a su ámbito de funcionamiento a fin de mejorar el sistema de abastecimiento pertinente en las entidades atendidas y alcanzar un nivel de eficiencia aceptable. En el INMP el mayor énfasis de atención está centrado en la facilitación de instrumentos actualizados eficaces, concentrados en la fase de selección de contrataciones de personal, pero no se centra en la etapa de la preparación del personal, dando prioridad a los lineamientos internos a desarrollar, como también se ha descuidado el ...

The most controversial institution incorporated into the Criminal Procedure Code of 2004 was the sentence of the acquitted, which is the power that the Superior Criminal Chamber has, when resolving the appeal that may have been filed against a previous acquittal sentence issued in favor of the accused (first instance), in being able to amend it in a conviction against this same procedural subject (second instance), sentencing decision that originally could only be questioned by means of the appeal of cassation. However, the national legislator, through Law No. 31592 of October 26th 2022, has decided to briefly reform this adjective norm, where the legal novelty is that this convicted person has the possibility of challenging his sentence via a new appeal, in which the Criminal Chamber of the Supreme Court is enabled to act as a judicial instance, this according to the exclusive rules of ...
