In this paper, we have performed a closed-form calculation of the radiation pattern of a base station antenna by using Ad Hoc Bessel-Fourier expansion. Once the coordinates system is fixed, we proceed to derived the magnetic potential vector underlining the complex part which is subsequently expanded in a Bessel-Fourier series. Since the radiation intensity is proportional to the square of the polar component of electric field, we used the well-known relation vec{E} \approx \vec{\nabla}\times \vec{\nabla} \times \vec{A} It gives capabilities to apply antenna data to the resulting closed-form expression for obtaining numerical estimations of the possible exposure levels. For this end, we measured the specific absorption radiation (SAR) to evaluate and discard possible effects of contamination by antenna radiation in the vicinity of the emission source. For a source of 2.0 GHz and 1.5 Vm-1...

This paper examines, including humor, the ludic function of language, which is faced dialectically with the referential function. Both are given the same importance, even though the latter is cognitively prior (Calvo 1994), so that there is no theoretical discrimination between what is purely ludic and linguistic of the joke or other styles of humor, and what is literature and the creation of worlds and characters through it. The humorous work par excellence: The Quixote is taken as an example. It is assumed at the same time that everything is humor whenever the sender and receiver agree with this, and the context is suitable: «The landlord, who, as has been mentioned, was something of a wag, and had already some suspicion of his guest’s want of wits, was quite convinced of it on hearing talk of this kind from him, and to make sport for the night he determined to fall in with his humo...

The rationale of this paper is to report by presenting data on the direct recognition of the canal that supplied water for over three hundred years to the city of Wari, from investigations with excavations in several sections of the channel, as a reference for qochas work, canals, reservoirs supplying the metropolis Wari (Perez 2006, 2007 and 2010) and as part of the hydrologic and hydraulic study of inca canal Wari Wari Yarccan or Yarcca in Ayacucho (Chavarría 2010). We believe that this is a great proyec for social and economic infraestructure that the Wari state executed in the Andes during the second half of the first millennium od the present Christian era, about 800 yerars before formation of the Empire of Tawantinsuyo.

The cocoa bean and its by-products are widely consumed in the world, due to their mineral content, functional compounds and antioxidant capacity, which vary according to how its processed. Fresh dried cocoa beans (FDB), dry fermented beans (FB) and cocoa paste (CP) were investigated, 31 samples in each case. Phosphorus, sodium, calcium, magnesium, copper, iron, zinc, manganese, cadmium lead, total polyphenols, anthocyanins, antioxidant capacity (ABTS, DPPH) expressed in Trolox equivalents (TE) were determined. Principal component analysis (PCA) was used. The mineral analysis established that 12 samples influenced CP1 and CP2. There was more calcium in the M26 sample of FDB, with 3.14%; potassium in the FDB, in M13, with 2.44%. Zinc in the FDB, was found in greater quantity in M30, M22, M23 and M9; with 90.46 ± 0.19 ppm in M30. Twenty-five samples reached values ≤ 0.61 ± 0.01 ppm of c...

In the present study were evaluated the bioactive compounds and antioxidant activity and satisfaction degree of a drink made with purple corn and stevia. Were used HPLC, ABTS, ORAC, DPPH methods and was done comparison according to the hedonic scale. Results showed close phenolic compounds to 2 mg/mL, high in anthocyanins (50,84 mg/100 mL) and antioxidant activity with ABTS (TEAC 17,96 pmol/mL), ORAC (31,01 μmol TEAC/mL) and DPPH (GAE 0,706 mg/mL). The useful life assessment revealed a synergistic effect between the purple corn anthocyanins and the active components of stevia. The satisfaction degree revealed that the formulation was described between "really like " (19%) and "like slightly " (33%) according to the hedonic scale about attributes of color, smell, taste and overall acceptability.

Historic military properties in the city of Lima have been experiencing changes in recent years due to the improvised growth of the city, resulting in the gradual loss of the functions and activities for which they were projected. The limited use of military infrastructure has contributed to the inescapable interest of the private sector for real estate development as these are considerable land extensions immersed in the urban fabric. These changes have been developed without prior analysis of their importance and heritage value for the city and its residents. The present investigation analyzes the case of Rafael Hoyos Rubio Fort in the district of Rímac to understand urban regeneration of these military heritage sites, reflected from the social and cultural perspectives. In the way, the study aims to identify the strengths and weaknesses of these urban en- claves to formulate short, ...

Dictionaries are a list of words, simple or complex, that are treated as entries (lexical items). It is usual to assert several components: the lemma or headword, named after its most neutral form, followed by an indication of the main inflections of its category: genre and number if they are names, syntactic class if they are verbs. Sometimes, indications of it are made in other aspects: etymology, pronunciation, marks of placement, area of use, register, frequency of use, etc.Among all the group, it is pointed out an area that grows daily, painstakingly, in lexicographic works: the pragmatic component. Most of the words are referential (names, verbs, adverbs), but others correspond to language functions like the expressive and appellative ones; for example, interjections. Many words are objective, but some others depend on subjectivity, such as p...

Concern for the quality of software-based systems has grown as software is integrated into every aspect of our lives. With the increase in the number of users and the data stored, more robust and secure databases are necessary. Quality control testing has progressed systematically from manual to automated applications. The Information Technology for Defense Company has the Center for Quality Standards and Security in charge of certifying and technically evaluating computer products, guaranteeing their quality. Currently the database review process in the SQLite manager is manual, making this process difficult, where there may be a margin of error due to the amount of checks that must be reviewed. The present work aims to develop a data architecture review component for the SQLite management server. For this, a study of a homologous database management system is carried out, the tools for...

This article examines the transformation of communication in the field of international relations, foreign policy, and diplomacy, moving from institutional and one-way approaches toward strategic, digital, and people-centered models. It analyzes how this evolution has led to a more participatory, emotionally intelligent form of public diplomacy, oriented toward dialogue with global audiences. Through a theoretical review, it explores the main approaches and dimensions of public diplomacy, its connection with soft power, and its adaptation to the digital environment through tools such as big data, bidirectionality, and emotional intelligence. The growing role of social media is highlighted in building genuine connections and promoting the international projection of national interests. In the case of Peru, a vision of digital public diplomacy is proposed that articulates identity, image, ...

The aim of this study was to characterize the morphology of the creole goat of the Volcanes de Colima physiographic sub-province, Mexico. Seventeen body measurements were taken from 371 goats older than two years and four racial indices and 17 functional indices were calculated. Data were analysed using Pearson correlation, principal component, and hierarchical cluster analysis. The rump angle, chest width and all measurements of the ears and udder showed the greatest variability. Also, the goats showed great morpho-structural harmony. Racial indices showed that goats are dolichocephalic, ellipometric, and have a convex rump, while functional indices indicated dual-purpose zootechnical aptitude. Four principal components explained 84.5% of the variation of body measurements. Rump angle, hearth girth, body length and ear l...
