Our team presents astrometric measurements of the PHA (52768) 1998 OR2 obtained close to its maximum approach to Earth. The observations were made from Observatorio Planetario Moche, located in Trujillo, Peru (Long. 79 00 39.2 W, Lat. 08 06 47.9 S, Alt. 48 m), on April 23, 24, 25 and 29, 2020. It is important to note that April 29's measurements were obtained approximately 5 hours before the asteroid's closest approach to Earth. A Celestron NexStar 11 GPS telescope and a ZWO ASI 071MC camera (without filter) were used. In addition, Dimension 4 software was employed to synchronize our time with special purpose Internet Time Servers. A total of 240 images were obtained, of which 19 were selected for presenting better ellipticity and FWHM values. The astrometric measurements were made with the Astrometrica software, using between 13 and 31 field stars identified by means of the Gaia DR1 cat...

The aim of this study was to determine the presence of hydrometra or pseudopregnancy in 38 dairy goats raised under intensive system. The diagnosis was done using transabdominal ultrasonography at 45 days of natural service. The affected goats were diagnosed as positive when the uterus presented a visible accumulation of fluid and presence of trabeculae in the image. The incidence of a hydrometra was of 5.3%. Both affected animals were successfully treated with commercial prostaglandin (PGF2α), and estruses occurred 4 days after the treatment. One goat got pregnant while the hydrometra recurred in the other goat.

La ciudad de Huaraz está inmersa en el proceso globalizador con valores capitalistas, contradictorios o antagónicos con el desarrollo armónico de los ecosistemas. Está viendo discurrir las aguas de sus glaciares, la destrucción de la composición armónica de sus paisajes, la desertización de sus mejores suelos de cultivo, la contaminación de sus activos naturales fundamentales (agua, suelo y aire) y la aculturizacion, entre otros impactos negativos significativos, que es urgente cuantificar y cualificar a través de la huella ecológica (HE).Se estimó la HE del distrito de Huaraz a través de una adaptación de la metodología de sus autores William Rees y Mathis Wackernagel, corno un indicador ambiental integrador del impacto que ejerce una comunidad humana sobre su ecosistema.Huaraz, tiene una HE total de 2,2 Ha/Hab y una capacidad de carga (CC) total de 1,1 Ha/Hab, consideran...

Jupiter radiates electromagnetic radiation in a broad spectrum. We are concerned here with the center part, usually referred as the decimetric radiation, a relatively flat part of the spectrum going from about 39.5 MHz merging into the thermal radiation at about 4GHz. The source of this radiation is synchrotron radiation emitted by energetic electrons, trapped in Jupiter's Van Allen radiation belt, gyrating around its magnetic field. The flux density of this radiation has been measured at many frequencies, the lowest being at around 80 MHZ.

Our team decided to collaborate with the campaign to observe the maximum approach of the PHA (66391) 1999 KW4, organized by the International Asteroid Warning Network (IAWN). The observations were made from CIEASEST, in the Universidad Nacional San Luis Gonzaga de Ica, Peru (Long. 75 44 12.5 W, Lat. 14 05 21.1 S, Alt. 401 m). A 60 cm Nishimura telescope (f10) and a ZWO ASI 071MC camera were used. The night of the maximum approach (May 25, 2019) we had cloudy skies; however, the night of May 26-27 we had clear skies and we were able to take 147 images with a exposure time of 4 seconds. Dimension 4 software was used to synchronize our time with special purpose Internet Time Servers, ensuring less than one second accuracy. The astrometric measurements were made with the Astrometrica software, using between 15 and 25 stars in the field identified by means of the Gaia DR2 catalog.

The study aimed to evaluate the rates of visual oestrous and conception in Saanen goats subjected to oestrus synchronization at two seasons of the year. Hormonal synchronization was done using an intravaginal sponge impregnated with medroxyprogesterone acetate (MAP), for 11 days. In addition, 48 hours before sponge removal, 300 IU equine chorionic gonadotropin (eCG) and 125 µg cloprostenol were administered. The goats that showed heat were mounted by fertile males. The pregnancy diagnosis was done 60 days after the service by transrectal ultrasound. The rate of presentation of heat was 86.7 and 96.7% for the anoestrous season (January-February) and the cyclicity season (March-April), respectively, without significant difference between periods. The conception rate was 88.5 and 62.1% for the periods January-February and March-April, respectively (p<0.05). It is concluded that the use ...
