Development and Research of the Sensitive Element of the MEMS Gyroscope Manufactured Using SOI Technology.

In this article, based on the developed methodology, the stages of designing the sensitive element of a microelectromechanical gyroscope with an open-loop structure are considered. This structure is intended for use in control units for mobile objects such as robots, mobile trolleys, etc. To quickly obtain a ready-made gyroscope, a specialized integrated circuit (SW6111) was selected, for the use of which the electronic part of the sensitive element of the microelectromechanical gyroscope was developed. The mechanical structure was also taken from a simple design. The simulation of the mathematical model was carried out in the MATLAB/Simulink software environment. The mechanical elements and the entire structure were calculated using finite element modeling with ANSYS MultiPhysics CAD tools. The developed sensitive element of the micromechanical gyroscope was manufactured using bulk micromachining technology-silicon-on-insulator-with a structural layer thickness equal to 50 µm. Experimental studies were carried out using a scanning electron microscope and a contact profilometer. Dynamic characteristics were measured using a Polytec MSA-500 microsystem analyzer. The manufactured structure has low topological deviations. Calculations and experiments showed fairly accurate results for the dynamic characteristics, with an error of less than 3% for the first iteration of the design.

Investigation and Research of High-Performance RF MEMS Switches for Use in the 5G RF Front-End Modules.

In this article, based on the developed methodology, the stages of designing two designs of high-performance radio-frequency single-pole single-throw microelectromechanical switches are investigated. These radio-frequency microelectromechanical switches are designed to operate at a central resonant frequency of 3.6 GHz and 3.4 GHz, respectively, as well as to work both in mobile communication devices and in the design of the architecture of 5G mobile networks, in particular in arrays of integrated antennas and radio-frequency interface modules. The manufacture and study of two designed structures are researched. For the first manufactured experimental sample in the open state the insertion loss is no more than -0.69 dB and the reflection loss is -28.35 dB, and in the closed state the isolation value is at least -54.77 dB at a central resonant frequency of 3.6 GHz. For the second in the open state the value of the insertion loss is no more than -0.67 dB and the reflection loss is -20.7 dB, and in the closed state the isolation value is not less than -52.13 dB at the central resonant frequency of 3.4 GHz. Both manufactured experimental samples are characterized by high linearity, as well as a small value of contact resistance in the closed state.

HEALTH DISORDER ASSOSIATED WITH PERMANENT DISABILITY AS THE SIGN OF BODILY HARM.

OBJECTIVE: The aim: The paper is aimed at creation of the procedure and criteria for determining a health disorder associated with permanent disability as a sign of serious bodily harm. PATIENTS AND METHODS: Materials and methods: To identify the problems faced by forensic medical and judicial practice in determining a health disorder associated with permanent disability, we studied more than 100 criminal proceedings from 2007 to the present time. RESULTS: Results: Ways to further improvement of the procedure for conducting expert studies on health disorders, associated with persistent loss of general ability to work as a characteristic feature of the bodily harm have been found to avoid errors in forensic medical and judicial practice. The issues of conducting forensic medical examinations to determine the degree of loss of general ability to work remain unresolved. The lack of joint research projects conducted by both medical and legal scientists leads to the polysemy and different approaches in the stating of certain concepts that are the subject of study of both medical and law sciences. Currently, the definition of the offence against health is debatable and the issues of criteria for determining such damage are not completely settled to date. CONCLUSION: Conclusions: We consider the development of the Procedure and Criteria for determining the degree (in percentage) of the permanent loss of general ability to work of victims of criminal offences, established by forensic medical experts, is crucial.

Genital mutilation as a consequence of criminal offence against a person.

OBJECTIVE: The aim: The paper is aimed at creation of a procedure for determining the loss of any body organ or its functions, genital mutilation, as the signs of grievous bodily harm, penalty for which is stipulated by the Article 121 of the Criminal Code of Ukraine, as well as establishing the possibilities of legal setting of the concept of "genital mutilation". PATIENTS AND METHODS: Materials and methods: Over 100 criminal proceedings, involving forensic medical examination, under the Article 121 of the Criminal Code of Ukraine for the period from 2007 to 19.05.2019 have been studied. Common methods of research have been used, namely, the analysis and synthesis, statistical method, as well as own observations of the process of judicial examination of the above criminal proceedings, as well as individual interviews, survey of the victims and their family members in total of 39 people. RESULTS: Results and conclusions: The findings of the investigation enabled detecting the gaps in the regulation of the procedure to define genital mutilation as a characteristic feature of grievous bodily harm. The ways of further improvement of the procedure of conducting expert studies of genital mutilation as a characteristic feature of bodily harm, which facilitates avoiding of errors in forensic medical and judicial practices have been found. The process of criminalization of the illegal conduct of surgical operations, resulted in mutilation of genitalia, must take place with the mandatory involvement of specialists in the field of practical medicine, as well as medical scientists specializing in sexopathology, gynecology, oncogynecology, forensic medicine in order to avoid errors in the lawmaking.

Mental illness as a consequence of criminal offence against the person.

OBJECTIVE: Introduction: Among crimes against human health we distinguish serious bodily harms, one of the signs of which is recognized as a mental illness. The aim:The paper was aimed at the development of the procedure for determining the mental disorder of a victim as a sign of a serious bodily harm, as well as the establishing the possibilities of clarifying the legislative formulation of the above norm of the Criminal Code. PATIENTS AND METHODS: Materials and methods: Over 300 criminal proceedings under the Arts.121, 122 and 125 of the Criminal Code of Ukraine for the period from 2007 to 2018 have been studied. For this purpose, common methods of research have been used, namely, the analysis and synthesis, as well as own observations of the process of consideration of the above criminal proceedings. RESULTS: Results and conclusions: The findings of the study assisted in identification of gaps in the regulation of the procedure to define mental illness as a characteristic feature of serious bodily harm. The ways of further improvement of the procedure of conducting expert studies of mental illness as a characteristic feature of a serious bodily harm. The rules for determining the psychic (mental) illness that are recognized by us as archaic and that does not correspond to the established procedure of such definition by the comprehensive forensic medical and forensic psychiatric examination involving a forensic medical expert, two or three psychiatrists (narcologists), summarizing in the conclusion of the presence of mental illness in a person, assessed by experts as a characteristic feature of serious bodily harm should be changed.

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project.

The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Has land use pushed terrestrial biodiversity beyond the planetary boundary? A global assessment.

Land use and related pressures have reduced local terrestrial biodiversity, but it is unclear how the magnitude of change relates to the recently proposed planetary boundary ("safe limit"). We estimate that land use and related pressures have already reduced local biodiversity intactness--the average proportion of natural biodiversity remaining in local ecosystems--beyond its recently proposed planetary boundary across 58.1% of the world's land surface, where 71.4% of the human population live. Biodiversity intactness within most biomes (especially grassland biomes), most biodiversity hotspots, and even some wilderness areas is inferred to be beyond the boundary. Such widespread transgression of safe limits suggests that biodiversity loss, if unchecked, will undermine efforts toward long-term sustainable development.

Global effects of land use on local terrestrial biodiversity.

Human activities, especially conversion and degradation of habitats, are causing global biodiversity declines. How local ecological assemblages are responding is less clear--a concern given their importance for many ecosystem functions and services. We analysed a terrestrial assemblage database of unprecedented geographic and taxonomic coverage to quantify local biodiversity responses to land use and related changes. Here we show that in the worst-affected habitats, these pressures reduce within-sample species richness by an average of 76.5%, total abundance by 39.5% and rarefaction-based richness by 40.3%. We estimate that, globally, these pressures have already slightly reduced average within-sample richness (by 13.6%), total abundance (10.7%) and rarefaction-based richness (8.1%), with changes showing marked spatial variation. Rapid further losses are predicted under a business-as-usual land-use scenario; within-sample richness is projected to fall by a further 3.4% globally by 2100, with losses concentrated in biodiverse but economically poor countries. Strong mitigation can deliver much more positive biodiversity changes (up to a 1.9% average increase) that are less strongly related to countries' socioeconomic status.

Ecological traits affect the sensitivity of bees to land-use pressures in European agricultural landscapes.

Bees are a functionally important and economically valuable group, but are threatened by land-use conversion and intensification. Such pressures are not expected to affect all species identically; rather, they are likely to be mediated by the species' ecological traits.Understanding which types of species are most vulnerable under which land uses is an important step towards effective conservation planning.We collated occurrence and abundance data for 257 bee species at 1584 European sites from surveys reported in 30 published papers (70 056 records) and combined them with species-level ecological trait data. We used mixed-effects models to assess the importance of land use (land-use class, agricultural use-intensity and a remotely-sensed measure of vegetation), traits and trait × land-use interactions, in explaining species occurrence and abundance.Species' sensitivity to land use was most strongly influenced by flight season duration and foraging range, but also by niche breadth, reproductive strategy and phenology, with effects that differed among cropland, pastoral and urban habitats. Synthesis and applications. Rather than targeting particular species or settings, conservation actions may be more effective if focused on mitigating situations where species' traits strongly and negatively interact with land-use pressures. We find evidence that low-intensity agriculture can maintain relatively diverse bee communities; in more intensive settings, added floral resources may be beneficial, but will require careful placement with respect to foraging ranges of smaller bee species. Protection of semi-natural habitats is essential, however; in particular, conversion to urban environments could have severe effects on bee diversity and pollination services. Our results highlight the importance of exploring how ecological traits mediate species responses to human impacts, but further research is needed to enhance the predictive ability of such analyses.

A global model of the response of tropical and sub-tropical forest biodiversity to anthropogenic pressures.

Habitat loss and degradation, driven largely by agricultural expansion and intensification, present the greatest immediate threat to biodiversity. Tropical forests harbour among the highest levels of terrestrial species diversity and are likely to experience rapid land-use change in the coming decades. Synthetic analyses of observed responses of species are useful for quantifying how land use affects biodiversity and for predicting outcomes under land-use scenarios. Previous applications of this approach have typically focused on individual taxonomic groups, analysing the average response of the whole community to changes in land use. Here, we incorporate quantitative remotely sensed data about habitats in, to our knowledge, the first worldwide synthetic analysis of how individual species in four major taxonomic groups--invertebrates, 'herptiles' (reptiles and amphibians), mammals and birds--respond to multiple human pressures in tropical and sub-tropical forests. We show significant independent impacts of land use, human vegetation offtake, forest cover and human population density on both occurrence and abundance of species, highlighting the value of analysing multiple explanatory variables simultaneously. Responses differ among the four groups considered, and--within birds and mammals--between habitat specialists and habitat generalists and between narrow-ranged and wide-ranged species.

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.
