By TB-LMTO-ASA method, calculation of the density of states is performed. charge density and electronic localization function topaz and its elements, with the aim of studying the links of its crystalline structure, that when subsequently irradiated with neutrons in the nucleus epiiérmicos reactor RP-1 O, defects will occur in the crystal lattice, changing its optical response. The results show that the aluminum atoms have higher mobilization probabilicfad, this is due to the weak link of the electron delocalization product

In this work the calculation was made ab-initio of the structure of bands and DOS of the Topaz with Fluoride (F) and Hydroxide (OH) in the fundamental state, with model TB-LMTO-ASA. The conventional cell of these 2 crystals does not present the same dimensions, due to the ion replacement F by molecules OH. The energy states will be affected by this new structure with OH, doing to vary the behavior of the bands, the DOS and therefore varying the optical properties of the crystal.

Using the base “Augmented Spherical Waves (ASW)” calculates and discusses the amounts “Crystal Orbital Overlap Population (COOP)” and “Crystal Orbital Hamiltonian Population (COHP)” of Silicon; that they give to information on the formation of bonding and antibonding states, and therefore on the stability in the system. The calculation is realized on Si with diamond cells and FCC, comparing it then for his later interpretation. The calculation of these structures they indicate us a strong instability of the Si FCC, producing a strong internal stress. This instability is due to the great quantity of antibonding states in the all crystal.

Permanent technological training favors teaching and its importance in learning modalities. Therefore, it is proposed to analyze the academic performance of permanent training in ICT skills for teachers and compare the performance of digital learning modalities. The research was quantitative, descriptive, cross-sectional in a higher education institution with continuous training processes. Two editions of courses were considered in which online TIC tools were taught for teachers. The activity records made it possible to analyze the academic performance of permanent training in TIC skills for teachers and compare the learning modalities' performance through them. In this sense, the results of the teaching-learning process in TIC skills reflect that the evaluations of the first b-learning modality course with 44 participants present a 98% approval rate compared to the second e-learning mod...

According to many researchers Wendell C. Bennett was the most important archaeologist of his time abroad. His profuse work led to it being considered as one of the founders of the Bolivian archaeological research. However, their contribution has been little considered in Peru, despite its many excavations in the valleys of Lambayeque and La Libertad; as well as iconic sites like Chavin and Huari. This rich information escapes our article, which will focus only on highlighting its work in the Lake Titicaca, considering excavated in key places like Tiwanaku and Chiripa, the first systematized information for this region. It is proposed that their approaches are still in place, often covertly in the interpretations of archaeologists interested in the highland region. Even their formulations achieved pan-Andean trim with its proposed ceremonial centers and Co-Tradition.

El gran crecimiento de la población hace latente y siempre presente la necesidad de comunicación, la dinámica económica primordial para su propio desarrollo y mejoramiento del ornato, llevándose a cabo mediante las infraestructuras viales, las relaciones sociales, culturales, etc. Cientos de millones de soles distribuidos del capital de fondos particulares, estatales, ministerios, gobiernos regionales, privados, además de horas – hombre, maquinarias y equipos se presupuesta y gastando en cada año en el mantenimiento, restauración y rehabilitación de vías así como en la construcción, ampliación y mejoramiento de nuevas carreteras. Esta dinámica también se centra en el casco urbano de una localidad, ciudad, capital, etc.; ya que Ias vías juegan un papeI importante en eI desarroIIo de estas y por lo tanto las condiciones inestables de los pavimentos perjudican ese desarrol...

The author reviews the actual criteria for the treatment of the advanced carcinoma of the cervix, he presents his experience of 55 cases treated with pelvic exenteration at the instituto Nacional de Enfermedades Neoplásicas, Lima Perú , between 1953 and 1965. The overall survival rate in his serie was 11 %; several tables with morbidity and mortality data are presented. The author remarks the circumstances and procedures useful for the opportune radical treatment of the advanced carcinoma of the cervix.

The problem of radical surgery in gynecological cancer was presented by Dr. Luis Esteves in relation to the casuistry and experience in the Dept. Of Obstetrics INEN of which he is chief from 1952 to 1959; after which he believed a duty to inform the society and gynecologists colleagues in general, the work accomplished in that period of seven years. This made the work refers exclusively to surgical treatment, noting that the radical and ultra-radical pelvic surgery cancer in women was introduced in our country, for him, with the cooperation of Dr. Castiellano in 1952. He also placed on record also in other centers, especially in the service of gynecology Pab 5 II Loayza Hospital, after other gynecologists grown in limited aspects of such radical surgery.

The authors have studied 9 cases of primary carcinoma of the Fallopian tube; this means an incidence of 0.09 % in a total of 9266 malignant tumors of the genital tract observed at the Instituto Nacional de Enfermedades Neoplásicas, Lima Perú, between 1952 and 1966. The patients had an average age of 50 years, range 33-70; the treatment was surgical and radiation, and the overall survival rate was 22 %.

Cervical cancer is currently the fourth most frequent type of cancer in women. A large number of techniques from the Artificial Intelligence (AI) such as Neuronal Networks, Support Vector Machines (SVM), Decision Trees and others; have been used to deal with the problem of predicting this disease. The following paper shows the cervical cancer risk prediction, by implementing a probabilistic model based on Bayesian Networks and using 322 instances where we could retrieve 15 different features that are known information from each patient. The tests were made using the 40% of the whole dataset, confusion matrix and AUC indicator. The results show that this work has raised a 96% of success rate as well as 0.9864 in terms of the AUC indicator, in addition to this, the results suggest that Bayesian Networks are able to reach a high performance and provide transparency during the inference proc...
