The selection of seismic inputs for nonlinear dynamic analysis is widely debated, mainly focusing on the advantages and disadvantages provided by the choice of natural, simulated, or artificial records. This work proves the differences in the structural behavior of RC buildings when using accelerograms with different levels of stationarity. Initially, nonlinear response under three sets of accelerograms equivalent in terms of pseudo acceleration spectrum is evaluated and compared. Then, the results of incremental dynamic analyses are compared by the statistical point of view considering different levels of irregularity for the reference structure.

Airborne signal intelligence (SIGINT) systems must be capable of locating radio signal sources. Direction finding (DF) to support this capability is an important factor. There are some practical considerations to be taken when designing the array configuration of a DF system for airborne SIGINT systems. This paper summarizes the practical factors when designing the array configuration of the DF system for airborne SIGINT. In particular, it focuses on four areas: antenna consideration factors when installing the DF system for airborne SIGINT from a practical point of view, array configuration methods for airborne communications intelligence and electronic intelligence, and a numerical analysis to select the optimum antenna position for airborne SIGINT.

After pointing out the importance of the hygrometer, both in a scientific and a practical point of view, the author goes into the question of the advantages and disadvantages attending the use of Daniell’s hygrometer, and the relative merits of this instrument and the dry and wet-bulb thermometers. Although satisfied of the accuracy of Mr. Glaisher’s Tables (founded on the Greenwich Observations), which show at once the relation of the temperature of evaporation to that of the dew-point, he was unwilling to abandon the use of Daniell’s apparatus for that of the wet and dry-bulb thermometers, slight as is the trouble of observing them, without personal experience of the correctness of the tables from which the dew-point was to be deduced. He therefore instituted a series of perfectly comparable observations by the two methods, and in this communication gives the results obtained from them during a period of twenty months. From a comparison of the dew-points determined by the two methods, he concludes that the results show in a striking manner the extreme accuracy of Mr. Glaisher’s Tables, and afford additional testimony to the value of the Greenwich Hygrometrical Observations, and the resulting formula on which those tables are founded. The author then refers to the subject of evaporation, and gives the results of his own observations at Whitehaven during six years, viz. from 1843 to 1848 inclusive. From these he states that the mean annual amount of evaporation is 30·011 inches; and the mean quantity of rain for the same period being 45·255 inches, the depth of the water precipitated exceeds that taken up by evaporation, on the coast in latitude 54½°, by 15·244 inches.

ABSTRACT Sulfur occurs naturally in the earth's crust as a pure element (native sulfur), as well as sulfide and sulfate minerals. From the biochemical point of view, sulfur is a vital element because it is a constituent of enzymes and other key proteins. In addition to modern uses of minerals, in old Iranian documents of traditional medicine, attention was paid to physico-chemical properties of minerals and the various methods of administration. In this review, the traditional usage of sulfur and sulfide minerals (e.g. orpiment, realgar and stibnite) and sulfate minerals (e.g. alum, jarosite, epsomite and melanterite) as documented in the Canon of Medicine of Avicenna (also known as Ibn Sina) and the Zakhireh Kharazmshahi of Jorjani, is compared with new findings about the advantages and disadvantages of these minerals in medical geology. The main conditions for the selection of mineral drugs was described first by Avicenna. There is a high correlation between old and modern pharmaceutical practices. The most important results concern the application of alum as a hemostatic agent (to inhibit hemorrhages), the use of jarosite as a method for treating osteoarthritis, the choice of melanterite for treating eczema, killing insects and as an anti-bacterial agent, the use of epsomite as an active ingredient in laxatives, homeostatics and mineral supplements, and the extensive use of sulfur in dermatology for its keratolytic effects and its supposed anti-microbial effects. In this review, newly developed pharmaceutical information about the use and effects on health of sulfide minerals will be compared to traditional pharmaceutical applications.

The article is devoted to practical aspects of using graphic programming tools in the educational process, and, particularly, to their application for performing laboratory classes in technical disciplines.The unpredictable rapid changing in conditions for providing education process due to coronavirus restrictions have required a new manner of how to conduct teaching in remote mode. This task urgently required to be resolved in the short term. But there were no published sources that contain practical advises and described real experience how to do this. Thus, the presented article is an attempt to close this gap. Due to results presented in the article this task could be resolved by using graphic programming languages that opens a field of possibilities for students in using models to explore properties of a real object by means of simulation of the virtual analog. It is argued the selection of programming system, the variations of beginning lessons are considered, the experience in using such system as Simulink is revealed. The advantages and disadvantages of the selected system are indicated from the point of view of its application to the educational process. There are some recommendations for building the sequence of laboratory classes on the base of graphic programming tools. In the beginning these models could be developed preliminary and delivered for students to explore them and then, with more students’ experience and skills, the models could be created by students themselves. The real experience obtained during on-line education phase demonstrates that this approach increases students’ interest for learning and accelerate the educational process. One more conclusion is that virtual laboratory classes as well as all other achievements in using remote mode of education should be implicated in the educational process when it returns to conventional mode of functioning.
