In the context of the spread of the coronavirus (Covid-19), worldwide, data has been reported on the number of positive cases, deaths, hospitalized, recovered, etc. In the case of Peru by the Ministry of Health (MINSA), from these an analysis is carried out, emphasizing the number of positive cases and deaths and taking as reference the behavior of a physical phenomenon, a number f is postulated, to describe the evolution of positive cases and deaths from coronavirus.

In the present study, the numerical simulation of marine currents in the Callao Bay was carried out, taking into account meteorological forcing forces,  the ELCOM Model (Estuary, Lake and Coastal Ocean Model) was adapted and con?gured, a 3D  hydrodynamic model designed for the numerical simulation of the hydrodynamics and  thermodynamics, the results of the simulation  show that the model can determine with a good approximation the spatial and temporal variation of the magnitude of the marine currents, which have been contrasted with ?eld measurements, obtaining as a result a minimum error of 1.39 % and maximum of 42.25 %. The model correctly simulated the surface level of the marine currents in the Callao Bay for the period of May 2016.

The propagation of light in 99,99 % of empty space existing in natural systems is investigated to a new level of description, assuming that light is the only inuence that can transmit information. First, the electromagnetic eld is considered as a non-inertial reference system and it is deduced by geometric reasoning that the propagation vector of the electromagnetic wave changes direction at each instant of time due to the angular velocity associated with the plane of vibration of the electric/magnetic eld. Consequently, the actual path of a ray of light would have the shape of a conical spiral. The geometric analysis of the path of light rays in a vacuum lead to a simple formulation of the parametric equations that would represent the essential kinematics of the points of the empty space of natural systems (the substrate). This leads to an equation that describes the variation of the sp...

As a consequence of the study on the variation of the speed of light with time in the underlying vacuum of natural systems, the concept of acceleration of light arises. From the set of parametric equations that express the substrate or essential kinematics of the vacuum, it is obtained a formula that describes the acceleration of light as a function of time. Two possible opposite directions for the acceleration of light are observed; these directions are correlated with the two possible opposite directions of the local vector quantum. The vector quantum, as well as the acceleration of light, would have intrinsic uctuations. For small uctuations, two complementary quasi-equilibrium conditions are established, which would explain why light rays are perceived in a straight line in ordinary free space. Correlations are also deduced for the uctuations of the opposite vector quanta, as well as...

The propagation of light is studied as a mechanism for the transmission of organized information through the underlying void of a resistant homogeneous medium. A substrate compatible with the inherent kinematic viscosity of the medium is constructed, which is defined by a system of parametric equations compatible with the properties of the medium. As a consequence, an equation is obtained for the speed of light that varies with time for a given magnitude of the local vector quantum associated with the resistant medium. The equation obtained indicates the transmission of organized information in the medium and shows a double direction that would be correlated with the opposite vector quanta. These vector quanta would not be exactly opposite and would exhibit excess and defect fluctuations reciprocally. Thus, for quasi-equilibrium states of the natural system, the fluctuations of the vecto...

The study of the speed of light in the underlying vacuum of a resistant medium, as a mechanism for transmitting information, is complemented by the study of the acceleration of light in said medium. Applying the second order time derivative to the parametric equations, which represent the substrate in the underlying void of the resistant medium, a formula is obtained that would describe the acceleration with which the organized information is transmitted. The equation obtained varies with time for a given magnitude of the local vector quantum, as well as the resistance coefficient described by the substrate. Two possible symmetrical directions for the acceleration of light in the underlying vacuum of the resistant medium are considered, which would be correlated with the two possible directions of the local vector quantum. Ignoring the local vectorial quantum, the formula allows determin...

The Inner Bay of Puno is located on Lake Titicaca in southern Peru, 2.6 m in average depth, 16.0 km in surface area. The mouth of the bay, populated by native reed beds, joins the Outer Bay through the north and south channels. The bay is an example of the negative impact of humans, where they discharge poorly treated wastewater, producing an increase in algal biomass, eutrophication and anoxia. The objective was to estimate the direction and magnitude of the speed of the water current, on an hourly scale controlled by relevant physical processes, between January 23 and 30, 2019. We collected meteorological data, depth and temperature of the water. We performed computational experiments using the ELCOM lake model. The rst scenario considered the closed bay, and as a result presented counterclockwise rotational ow in the north and clockwise in the south, with a speed that varied between 0...

This work, has allowed us to process and analyze the data obtained about the perception of students in the face of the virtual teaching of physical sciences in the academic system of university training at this stage of pandemic, product of the Covid-19; the system of education under the health emergency was abruptly changed from the modality of classical face-to-face education to a new mode of virtual education. For this work, around 100 students were surveyed basic science faculties such as Physical Sciences and Biological Sciences, as well as the Professional School of Education and the Professional School of Education and the Professional School of Electrical Engineering of the National University of San Marcos, this survey was conducted at the end of the 2020-I semester. A survey form was applied with 16 questions to be answered by students, those questions were regarding: 1. Traini...

The present research has allowed us to determine the X-ray spectrum, for this we have designed a computational program through iterative calculation, samples of attenuation data have been taken and then a previously designed program has been used with a programming language, with the attenuation data. For our case we have worked with the Aluminum and Copper lters. This research has allowed us to: 1.- Find the spectra of X-ray radiation. 2.- Design a program that allows us to nd the X-ray spectra, which we must compare with the X-ray spectra previously determined by Tominaga (1981). 3.- Design a Visual X-ray Dosimetry Program. The expected result is the obtaining of the radiation spectra and the optimization of the X-ray dosimetry, based on the designed program.
