Authors: Wen Yafei , Zhou Pai , Xu Zhongxiao , Yuan Liang , Wang Minjie , Wang Shengzhi , Chen Lirong , Wang Hai
Published: December 2019

The storage and retrieval efficiency (SRE) and lifetime of optical quantum memories are two key performance indicators for scaling up quantum information processing. Here, we experimentally demonstrate a cavity-enhanced long-lived optical memory for two polarizations in a cold atomic ensemble. Using electromagnetically induced-transparency (EIT) dynamics, we demonstrate the storages of left-circularly and right-circularly polarized signal light pulses in the atoms, respectively. By making the signal and control beams collinearly pass through the atoms and storing the two polarizations of the signal light as two magnetic-field-insensitive spin waves, we achieve a long-lived (3.5 ms) memory. By placing a low-finesse optical ring cavity around the cold atoms, the coupling between the signal light and the atoms is enhanced, which leads to an increase in SRE. The presented cavity-enhanced storage shows that the SRE is ∼30%, corresponding to an intrinsic SRE of ∼45%.
Reconstructing complex refractive-index of multiply-scattering media by use of iterative optical diffraction tomography
Authors: Fan Shengli , Smith-Dryden Seth , Li Guifang , Saleh Bahaa
Published: December 2019

Conventional optical diffraction tomography (ODT) techniques fail in the presence of multiple scattering, and the problem becomes even more challenging when the medium is also lossy. Iterative ODT (iODT), which was shown recently to be more tolerant to multiple scattering than conventional ODT, is here augmented with an error-subtraction (ES) module. Numerical results demonstrate the accuracy and efficiency of iODT with ES for reconstructing multiply-scattering objects with complex refractive index.

Published: December 2019

Photonic delay-based reservoir computing (RC) has gained considerable attention lately, as it allows for simple technological implementations of the RC concept that can operate at high speed. In this paper, we discuss a practical, compact and robust implementation of photonic delay-based RC, by integrating a laser and a 5.4 cm delay line on an InP photonic integrated circuit. We demonstrate the operation of this chip with 23 nodes at a speed of 0.87 GSa/s, showing performances that is similar to previous non-integrated delay-based setups. We also investigate two other post-processing methods to obtain more nodes in the output layer. We show that these methods improve the performance drastically, without compromising the computation speed.
Close look on cubic Tm:KY3F10 crystal for highly efficient lasing on the 3H4 → 3H5 transition
Authors: Guillemot Lauren , Loiko Pavel , Soulard Rémi , Braud Alain , Doualan Jean-Louis , Hideur Ammar , Camy Patrice
Published: December 2019

We report on Czochralski growth, detailed ground- and excited-state absorption and emission spectroscopy and highly-efficient mid-infrared (∼2.3 µm) laser operation of a cubic potassium yttrium fluoride crystal, Tm:KY3F10. The peak stimulated-emission cross-section for the 3H4 → 3H5 transition is 0.34×10−20 cm2 at 2345 nm with an emission bandwidth exceeding 50 nm. The excited-state absorption spectra for the 3F4 → 3F2,3 and 3F4 → 3H4 transitions are measured and the cross-relaxation is quantified. A continuous-wave 5 at.% Tm:KY3F10 laser generated 0.84 W at 2331-2346 nm by pumping at 773 nm, with a record-high slope efficiency of 47.7% (versus the incident pump power) owing to the efficient action of energy-transfer upconversion leading to a pump quantum efficiency approaching 2. The first Tm:KY3F10 laser with ESA-assisted upconversion pumping (at 1048 nm) is also demonstrated. Due to its broadband emission properties, Tm:KY3F10 is promising for ultrashort pulse generation at ∼2.3-2.4 µm.
Angular dispersion boost of high order laser harmonics with Carbon nano-rods
Authors: Lécz Zsolt , Andreev Alexander A.
Published: December 2019

Periodic surface gratings or photonic crystals are excellent tools for diffracting light and to collect information about the spectral intensity, if the target structure is known, or about the diffracting object, if the light source is well defined. However, this method is less effective in the case of extreme ultraviolet (XUV) light due to the high absorption coefficient of any material in this frequency range. Here we propose a nanorod array target in the plasma phase as an efficient dispersive medium for the intense XUV light which is originated from laser-plasma interactions where various high harmonic generation processes take place. The scattering process is studied with the help of particle-in-cell simulations and we show that the angular distribution of different harmonics after scattering can be perfectly described by a simple interference theory.
Computer-generated photorealistic hologram using ray-wavefront conversion based on the additive compressive light field approach
Authors: Wang Z. , Zhu L. M. , Zhang X. , Dai P. , Lv G. Q. , Feng Q. B. , Wang A. T. , Ming H.
Published: December 2019

The conventional computer-generated hologram reconstructing photorealistic three-dimensional (3D) images based on ray-wavefront conversion has the disadvantage of spatio-angular resolution trade-off. In this Letter, we propose for the first time, to the best of our knowledge, a computer-generated photorealistic hologram without spatio-angular resolution trade-off based on the additive compressive light field (CLF) approach. The original light field is compressed into multiple layer images through numerical optimization based on the additive light field principle. Then, by independently calculating the wave propagation from each layer image to the hologram plane and adding them together, a CLF hologram is generated. Since the CLF information is presented through a holographic method, the advantage of high resolution in CLF is preserved while the limitation of the number of physically stacked layers (such as liquid crystal displays) is removed, leading to higher quality, larger depth of field, and higher brightness compared with a conventional CLF display. The proposed method is verified with a photorealistic optical experiment.
Spin-Hall effect of light and its enhancement in multilevel atomic system
Authors: Wu Jinze , Zhang Junxiang , Zhu Shiyao , Agarwal Girish S.
Published: December 2019

Using the sensitivity of atomic transitions on the polarizations of pump fields in multi-Zeeman-sublevel atomic systems, we show the polarization-direction-dependent anisotropic susceptibility of atoms that yields the strong coupling between the spin and the transverse momentum of light, i.e., spin–orbit interaction (SOI). Moreover, we also show that the spin-Hall effect of light can be obtained due to SOI. It can be controlled via the orientation of the anisotropy and frequency of light, and substantially enhanced up to several micrometers, which could be easily observed in experiment.
Journalistic confidentiality in an age of data surveillance
Authors: Ananian-Welsh Rebecca
Published: December 2019

This article examines two key components of the Australian Government’s data surveillance framework and critiques their impact on journalistic confidentiality. The 2015 mandatory data retention scheme and the 2018 telecommunications industry assistance scheme have been the subjects of considerable controversy and ongoing parliamentary reviews. The combined effect of these provisions is that journalists are unable to confidently fulfil their ethical obligation to maintain source confidentiality. The article recommends targeted reforms to more explicitly and appropriately balance the public interest in journalistic confidentiality (and relatedly, democracy, public accountability and the rule of law) against law enforcement and national security objectives.
Restaging Feminism: The Activist Retrospective
Authors: Davidson Jane Chin
Published: December 2019

In the context of retrospective exhibitions, feminist restaging signifies a performative 'redoing' in a circuit of repetition that re-envisions, reinvents and remakes the discriminatory absences in history. In this article, the activism of restaging will be explored through the curatorial methods employed to memorialize Ana Mendieta's artistic legacy. Feminist strategies differ from the norms of canonical practices used in traditional career retrospectives, such as those for Mendieta's husband, Carl Andre. In another example of restaging, the 2011 re-presentation of Judy Chicago's works in Setting the Table created the opportunity to exhibit simultaneously Margarita Cabrera's sewing project in collaboration with Mexican artists. Restaging inaugurates the past and present of feminist collectivities, establishing a transnational activist model for repeat exhibitions.
Syphilis in Coimbra at the beginning of the 20th century. The importance of hospital records for the study of the disease
Authors: Lopes Célia
Published: December 2019

Syphilis is a chronic sexually or congenitally transmitted infection, with a well-documented clinical past, having been one of the major public health problems in Europe. In Portugal, there is a lack of data regarding the number of individuals infected by syphilis, or even about the characteristics of the disease and the infected people, in past official statistics. Hence, the main purpose of this study was to appraisal some of these omissions in order to extend our knowledge of this infection in the past. The aim was to obtain data about the disease in the first years of the 20th century, as well as the demographic and the socioeconomic profile of the affected individuals. The intention was also to characterize the disease, identifying the most frequent lesions and their locations in the human body. Among the patients who were hospitalized in the Hospitals of the University of Coimbra (HUC) between 1904 and 1937, 5.9% were diagnosed with syphilis. Most of them (89.3%) with the acquired form of the disease, which affected mainly single young adults (20–39 years) independently of their sex. Congenital syphilis was detected mainly in children (0–4 years). Most hospitalizations for congenital syphilis (53.9%) occurred when the disease was in its tertiary form, which did not happen in the acquired form of the disease (29.5%). The most frequent forms of tertiary syphilis were malignant, affecting 33.4% of patients with the disease at its most advanced stage.
Seismic Velocity Analysis for Improved Geopressure Modelling in Onshore Niger Delta
Authors: Bassey Umoren Emmanuel , Daniel Uko Etim , Tamunobereton-Ari Iyeneomie , Israel-Cookey Chigozie
Published: December 2019

In this study, an improved evaluation of pore pressure using a model based seismic inversion technique has been carried out. Across six wells in the Onshore Niger Delta Basin, post stack seismic volume, angle stack gathers, seismic horizons, check shot, wireline logs, drilling and pressure data were analysed and interpreted. The model based inversion technique was applied to improve the seismic resolution as well as derive acoustic impedance using well velocities along with stacking velocities from velocity analysis of the 3D seismic data. Bowers’ Vp-VES coefficients of 7.43 and 0.77 were used to transform the derived seismic acoustic impedance velocity into seismic pore pressure cube. The seismic acoustic impedance interval velocity reveals much of the geology and resulted to a high resolution seismic pore pressure cube when compared at well location with direct pressure data. The Derived Seismic Pore Pressure (DSPP) also revealed that pore pressure and overpressure can reach or exceed 4000 and 1000psi respectively in the field. The results obtained have demonstrated that seismic acoustic impedance volume can offer high resolution seismic pore pressure cube in both time and space.
An analysis of college and career readiness emphasis in ESSA state accountability plans
Authors: Hackmann Donald G. , Malin Joel R. , Bragg Debra D.
Published: December 2019

This study examined the extent and manner in which college and career readiness (CCR) is emphasized in Every Student Succeeds Act (ESSA) state accountability plans. We analyzed 52 plans (50 states, DC, Puerto Rico) using frameworks developed by Cook-Harvey, Darling-Hammond, Lam, Mercer, and Roc (2016) and Dowd and Bensimon (2015). Findings disclose significant variation, with CCR featuring prominently in some plans and receiving cursory mention in others. Most states identified CCR components as part of their school quality or student success indicators but few used ESSA to restructure their state initiatives to address persistent inequities. Even states making CCR a central feature typically applied color-blind approaches, addressing CCR for all students rather than developing CCR plans to address inequitable outcomes for student subgroups.
Brain stem – from general view to computational model based on switchboard rules of operation
Authors: Duch Włodzisław , Mikołajewski Dariusz
Published: December 2019

Despite great progress in understanding the functions and structures of the central nervous system (CNS) the brain stem remains one of the least understood systems. We know that the brain stem acts as a decision station preparing the organism to act in a specific way, but such functions are rather difficult to model with sufficient precision to replicate experimental data due to the scarcity of data and complexity of large-scale simulations of brain stem structures. The approach proposed in this article retains some ideas of previous models, and provides more precise computational realization that enables qualitative interpretation of the functions played by different network states. Simulations are aimed primarily at the investigation of general switching mechanisms which may be executed in brain stem neural networks, as far as studying how the aforementioned mechanisms depend on basic neural network features: basic ionic channels, accommodation, and the influence of noise.
Occurrence of Aflatoxin M1 in Milk-based Mithae samples from Pakistan
Authors: Naz Narjis , Abbas Mateen , Rubab Anam , Kanwal Kinza
Published: December 2019

Milk products with aflatoxin M1 (AFM1) contamination are a lethal dilemma worldwide due to their carcinogenic and mutagenic effects especially in developing countries. This study investigated the occurrence of AFM1 in milk-based mithae samples marketed in Lahore, Pakistan. Two hundred (n = 200) different types of mithae samples were analyzed for AFM1 using a HPLC florescence detector. Results showed that AFM1 was present in 76% of the analyzed samples, of which more than 80% had a much higher level of AFM1 than the European Union permissible level of i.e.0.05 μg/kg in milk products. The aflatoxin M1 in all the tested samples was observed in the range of 0.004 to 1.49 μg/kg. On average, the Gulab Jamun and Malai Laddu showed the highest level of aflatoxin M1 i.e. 1.49 and 1.17μg/kg, respectively. The lowest amount of aflatoxin M1 was found in Kalakand samples 0.004μg/ kg. The conclusion drawn from this data revealed that almost three-fourths of the mithae samples were highly contaminated with AFM1 due to their main component, milk. The consumption of milk-based mithae is popular due to health benefits as well as being part of tradition. Instead of being nourishing and beneficial, it is been found to be hazardous to human health due to aflatoxin contamination. Continued monitoring of aflatoxin M1with strict rules and regulations is required to prevent aflatoxin accumulation in this favorite food commodity.

This paper introduces the more general result on existence, uniqueness and boundedness for solutions of nonstandard Volterra type integral equation on an arbitrary time scales. We use Lipschitz type function and the Banach’s fixed point theorem at functional space endowed with a suitable Bielecki type norm. Furthermore, it allows to get new sufficient conditions for boundedness and continuous dependence of solutions.
Das Zeugnis der Holocaustüberlebenden: Gewissheit, Skeptizismus, Relativismus
Authors: Kusch Martin
Published: December 2019

To date philosophical reflections on the Holocaust and Holocaust survivor testimony have come almost exclusively from authors in the so-called “Continental tradition”. This paper is an attempt to contribute to the scholarship on Holocaust survivor testimony using some of the concepts and conceptions of “analytic philosophy”, more precisely, some of Ludwig Wittgenstein’s remarks in On Certainty. The paper uses these remarks to analyse the “linguistic despair” expressed by many Holocaust survivors when trying to put their horrendous experiences into words.

Survey on SAP and its application in public-key cryptography
Authors: Goel Neha , Gupta Indivar , Dass B. K.
Published: December 2019

The concept of the semigroup action problem (SAP) was first introduced by Monico in 2002. Monico explained in his paper that the discrete logarithm problem (DLP) can be generalized to SAP. After defining the action problem in a semigroup, the concept was extended using different mathematical structures. In this paper, we discuss the concept of SAP and present a detailed survey of the work which has been done using it in public-key cryptography.

Authors: Wanasinghe Dilani , Shah Shetal , Bamanikar Amruta , Aboudi David , Mikkilineni Soumya , Shyong Olivia , Wu Natasha , Lavan Tessa , Brumberg Heather L.
Published: December 2019

Objective

To assess lifestyle characteristics among parental electronic cigarette (e-cigarette), marijuana and tobacco users.

Methods

A total of 1214 parents (77% mothers and 23% fathers) were surveyed and categorized into five exposure groups: e-cigarette use only (1%), marijuana use only (3%), tobacco products only (10%), multi-exposed [11% (marijuana, e-cigarette and tobacco)], and non-users [75% (no e-cigarette, tobacco or marijuana)].

Results

Similar to non-users, the e-cigarette group had no illicit drug use. Further, e-cigarette users were more likely, in adjusted models, to self-identify as non-smokers and exercise compared with tobacco and multi-exposed groups. Although marijuana users also had higher odds of self-identifying as non-smokers compared to tobacco and multi-exposed groups, they were more likely than non-users to drink alcohol.

Conclusion

E-cigarette and marijuana using parents were less likely to identify as smokers. E-cigarette users had healthier lifestyle characteristics than the other exposed groups. Clinicians should consider specifically screening for parental e-cigarette and marijuana use as assessing for only “smoking” may underrepresent first-and second-hand exposure. Additionally, clinicians should be aware that marijuana using parents are more likely to drink alcohol and should counsel accordingly.
Disentangling the source of non-stationarity in a panel of seasonal data
Authors: Hsu Shih-Hsun
Published: December 2019

In dealing with a panel of seasonal data with cross-section dependence, this paper establishes a common factor model to investigate whether the seasonal and non-seasonal non-stationarity in a series is pervasive, or specific, or both. Without knowing a priori whether the data are seasonal stationary or not, we propose a procedure for consistently estimating the model; thus, the seasonal non-stationarity of common factors and idiosyncratic errors can be separately detected accordingly. We evaluate the methodology in a series of Monte Carlo simulations and apply it to test for non-stationarity and to disentangle their sources in panels of worldwide real exchange rates and of consumer price indexes for 37 advanced economies.
Autobiographical memory increases pupil dilation
Authors: El Haj Mohamad , M. J. Janssen Steve , Gallouj Karim , Lenoble Quentin
Published: December 2019

Background

Pupil activity has been widely considered as a “summed index” of physiological activities during cognitive processing.

Methodology

We investigated pupil dilation during retrieval of autobiographical memory and compared pupil diameter with a control condition in which participants had to count aloud. We also measured pupil diameters retrieval of free (i.e., first memory that comes to mind), positive, and negative memories (memories associated, respectively, with the words “happy” and “sad”).

Results

Analyses demonstrated larger pupil diameters during the free, positive, and negative autobiographical memory retrieval than during the control task. Analyses also demonstrated no significant differences in pupil diameters across the three autobiographical memory conditions.

Conclusion

These outcomes demonstrate that, compared with counting, autobiographical retrieval results in a larger pupil size. However, the emotional valence of memories yields non-significant effect on pupil diameters. Our findings demonstrate how autobiographical memory retrieval yields pupil dilation.
Clinicians’ perceptions of the implementation of the Structured Assessment of Protective Factors for violence risk (SAPROF) on an inpatient forensic unit

Published: December 2019

The Structured Assessment of PROtective Factors for Violence Risk (SAPROF) is an assessment tool that examines protective factors when assessing for violence risk. There is limited research on clinicians’ perceptions of the use and implementation of risk assessment tools, and this study aimed to examine the experiences of clinicians using the SAPROF in a low secure forensic rehabilitation inpatient unit in Canada. An exploratory research design was used, and five clinicians participated in semi-structured interviews. Data was analyzed using a thematic approach and three central themes were identified: understanding of the patient from a strengths-based point of view, providing clinicians with a focus on how to help the patient, and bringing in opportunities to collaborate as a team. The findings highlight the additional value of the SAPROF as tool in helping forensic teams to adopt strengths based approaches to risk assessment, enhancing treatment planning and inter-professional collaboration.

Multiplicative Stochastic Model of the Time Interval between Trades in Financial Markets
Authors: Gontis V.
Published: December 2019

Stock price change in financial market occurs through transactions, in analogy with diffusion in stochastic physical systems. The analysis of price changes in real markets shows that long-range correlations of price fluctuations largely depend on the number of transactions. We introduce the multiplicative stochastic model of time interval between trades and analyze spectral density and correlations of the number of transactions. The model reproduces spectral properties of the real markets and explains the mechanism of power law distribution of trading activity. Our study provides an evidence that statistical properties of financial markets are enclosed in the statistics of the time interval between trades. Multiplicative stochastic diffusion may serve as a consistent model for this statistics.

Authors: Baronas R. , Ivanauskas F. , Kulys J.
Published: December 2019

A mathematical model of amperometric biosensors has been developed to simulate the biosensor response in stirred as well as non stirred solution. The model involves three regions: the enzyme layer where enzyme reaction as well as mass transport by diffusion takes place, a diffusion limiting region where only the diffusion takes place, and a convective region, where the analyte concentration is maintained constant. Using computer simulation the influence of the thickness of the enzyme layer as well the diffusion one on the biosensor response was investigated. The computer simulation was carried out using the finite difference technique.

We present here a numerical study of laminar doubly diffusive free convection flows adjacent to a vertical surface in a stable thermally stratified medium. The governing equations of mass, momentum, energy and species are non-dimensionalized. These equations have been solved by using an implicit finite difference method and local non-similarity method. The results show many interesting aspects of complex interaction of the two buoyant mechanisms that have been shown in both the tabular as well as graphical form.
Anonymous Internet Creative Writing as a Means of Modern Communication (On the Question of the Study of Anonymous Internet Parodies)
Authors: Belovodskaja Anastasija
Published: December 2019

The focus of the whole “Internet space” on communication and the availability of technical possibilities makes the spread of information on the Internet practically unrestricted. This in turn leads to the transformation of the Internet communication model, which could be represented as “WE” – ”WE” in relation to anonymous Internet texts, when not an individual, but “the faceless crowd” or “Anonymous” appears to be both the sender and the addressee of the message. This article points out that in anonymous creative writing, even “mute” text sending and its placement on Internet diary pages is an expression of a particular attitude; in the case of parody, it is also a means of rethinking the events within the context provided by the parody. Alongside parody’s entertaining character, which contributes to the text’s attractiveness and ease of perception, it can be a powerful weapon allowing the author to reframe a particular situation. At the same time, the monitoring of anonymous Internet parodies from the point of view of the underlying prototexts may be a means of identifying the most important precedent phenomena, which are used repeatedly and form a part of the Internet-users’ collective cognitive base. The transformations of texts that occur when the texts are parodied reflect corresponding changes in the consciousness of their anonymous author-users. Thus, the analysis of anonymous “Internet creative writing” may appear to be quite an effective way to study the processes of social consciousness, both declared overtly and covert.
Language Personality in the Russian Linguistic Tradition: Diachronic-Synchronic Aspects
Authors: Yudina Natalia
Published: December 2019

The article is devoted to the analysis of one of the most important terms in modern linguistic usage – the definition of a language personality. It was introduced in Russian-language scientific use in the 1930s by academician V. Vinogradov, and has been related to the ever-increasing interest in the anthropocentric factor in language, as well as to changes in the scientific linguistic paradigm, since the 1980s. Resuming some terminological and conceptual descriptions of language personality, as represented in the Russian-language linguistic literature, this article comes to the conclusion that language personality theory is presently reviewed in linguodidactics, linguoculturology, cognitive linguistics, ethnolinguoculturology, psycholinguistics, lexicography, stylistics, pragmatics, and other intra- and extralinguistic disciplines.The complex analysis makes it possible to identify verbal-semantic (lexicon), linguocognitive (thesaurus), motivational (pragmaticon; cf.Y. N. Karaulov), stylistic, communicative-pragmatic, linguoculturological, emotional, articulatory, and other levels. In addition to language personality, the terms verbal and communicative personality must also be specified and systematized. Further conceptual and terminological research in the description of language personality seems highly necessary for modern linguistics. The process of developing and establishing a language personality appears to be an essential component of the objective and subjective transformations of the information society. Further inquiry into the study of language personality will contribute to a better understanding of the social-political, economic, socio-cultural and linguistic processes occurring in the 21st century.

PrEP and Adolescents: The Role of Providers in Ending the AIDS Epidemic
Authors: Hosek Sybil , Henry-Reid Lisa
Published: December 2019

Surveillance data on high school adolescent sexual activity, including teenaged pregnancy rates and incidence of sexually transmitted infections (STIs), require pediatricians and other youth providers to be competent and confident in addressing sexual and reproductive health care needs in adolescent and/or young adult populations. The American Academy of Pediatrics has published guidelines, recommendations, clinical reports, and resources on the promotion of healthy sexual development in clinical settings, encouraging sexual health assessments that are inclusive of HIV and STI testing as an integral component of comprehensive health visits. The need for a more determined effort to address sexual health as it relates to HIV specifically is evidenced by a decrease in the number of in-school youth reporting ever being tested, 15- to 24-year-olds representing 21% of new infections, and estimates that >40% of youth with HIV are undiagnosed. Ending the HIV epidemic requires adherence to published HIV testing recommendations, sexual health assessments, screening for STIs, and appropriate primary and secondary prevention education. Preexposure prophylaxis, an efficacious biomedical prevention intervention for reducing HIV acquisition, was approved in July 2012 and in May 2018 was authorized for use in minors. This state-of-the-art review article provides background information on preexposure prophylaxis, current guidelines and recommendations for use, and strategies to introduce and implement this valuable HIV prevention method in clinical practice with adolescents and young adults.

The results of a generalized analysis of the assessment of the development of socio-economic systemsof the region, carried out according to the documents of strategies and development plans in comparisonwith the actual achievements of the development strategies of the Dnipropetrovsk region. The analysis wascarried out according to statistical reporting and analytical reports on the results of the implementation ofregional development projects and analytical notes of experts. The system failure of these projects is shown.Among the factors influencing the state, the lack of timely, high-quality and full assessment of the results ofthe development processes was identified. The analysis used expert and statistical information indicators ofperformance, their total and index comparison, estimates of the dynamics of changes and integral estimates.and index comparisons, the dynamics of their changes without analyzing the causes of negative deviationsare used. It is determined that there is no single information and analytical basis for the methodologicalassessment of results. Based on the processing of scientific, legislative sources and practical information onthe selection and justification of development strategies and plans, the results of a generalized analysis ofthe state of socio-economic development and the implementation of project activities in the Dnipropetrovskregion are presented. It is noted that the methodological tools of analysis use only expert and statisticalindicators, their total and index comparisons and the dynamics of changes without analyzing the causes ofnegative deviations. There is no single information base for the assessment methodology. The necessity ofcombining the implementation of one-time and episodic measures to assess the state, quality and effectivenessof development processes with the systematic implementation of analytical measures is shown. Attention isdrawn to the need to increase the competencies of persons carrying out analysis and assessment of the state ofdevelopment processes and formulate conclusions on the development of territorial communities. It is provedthat qualitative assessment should be considered as the main tool to increase managerial impact on the impactof development processes by creating a single integrated information-analytical assessment system usingmathematical models, computer technologies and their software.
The innovative models of functioning of anti-corruption bodies in the world
Authors: Канан Аюб
Published: December 2019

Models of formation and development of anti-corruption institutions are analyzed in thearticle. The modern anti-corruption bodies of state power that exist in Germany, Hungary, Finland,Albania, Romania, Lithuania and Latvia are considered.It has been found that in most European countries specialized anti-corruption bodies have beenestablished as an important element of the anti-corruption strategy. The author analyzes the experienceof developing anti-corruption institutions in Lithuania, Romania, Finland, Norway, Germany, Albaniaand others. and found that in Europe there is no one universal model of the anti-corruption body. Theanalysis showed that there are similar law enforcement agencies, corruption prevention services, anticorruptionstrategy management, and multi-purpose organizations. In some countries, several anticorruptionagencies have been set up, and several such institutions can deal with both corruption andother issues. Romania's experience with the implementation of the National Anti-Corruption Directorate,which includes not only exposing corruption but also investigating corruption offenses, is effective.Based on the analysis of the system of anti-corruption institutions in European countries,it should be noted that there are three models of formation and development of anti-corruptioninstitutions, in particular:1) there are no specially created anti-corruption institutions, and the functions of preventingand combating corruption are delegated to law enforcement and / or judicial bodies;2) which established a single anti-corruption institution;3) in which the system of anti-corruption bodies of state power operates.Ukraine belongs to the third model, because in our country a system of state authorities isestablished and operates, which implement state policy in the sphere of combating corruption.

The ability of bacteria to quickly acquire antibiotic resistance and transfer it among different groups are created a global problem, since antibiotics are used not only in medicine, but also in agriculture. That is why to study of the antibiotic sensitivity of not only pathogenic bacteria, but also of beneficial microbes like Bacillus spp. is extremely important. Our results demonstrated that all the studied strains of the B. subtilis group were highly sensitive to cephalexin and enrofloxacin, while resistant to oxacillin. The B. subtilis B-5449 strain was the least resistant to the studied antibiotics, and the B. subtilis B-2896 strain was the most resistant.

Successful experiments on olfactory enrichment of clove oil in Russian zoos have been carried out. Olfactory enrichment with clove oil reduced or eliminated stereotypical behavior (pacing) in most Amur tigers, African lions, and some Canadian and Red wolves. The behavior of the Far Eastern leopard and the Snow leopard behavior has not changed significantly under the influence of clove essential oil. Olfactory enrichment of clove essential oil is more successful for young animals.

The morphological and anatomical features of the assimilation apparatus Taraxacum officinale Wigg., growing under the conditions of a rock dump of the Kedrovsky coal mine in the Kemerovo Region, were studied. It was experimentally established that the specific environmental conditions of the rock dump cause morphological and anatomical changes in the leaves of the dandelion. At the level of leaf morphology, there is a decrease in the average leaf area, thickening of leaf blades, the formation of a trend towards a decrease in the number of leaves in the outlet. At the level of the anatomical structure, there is a significant increase in the thickness of mesophyll, a tendency to a decrease in the thickness of the tissues of the upper and lower epidermis, a decrease in the number of cells of the upper and lower epidermis by 1 mm2 and an increase in the size of stomata in the tissues of the lower and upper epidermis, a decrease in the number of stomata by 1 mm2 and stomatal index on the upper epidermis. Under the conditions of the rock dump, an increase in the number of reliable correlations between the anatomical parameters of the leaf of Taraxacum officinale Wigg., as well as anatomical signs with indicators of atmospheric pollution, was established, to a greater extent due to the formation of positive correlations that are known to control the development of biosystems and are critical for body periods.

The research shows, that an increase of phytocoenoses provided an increase of phytomass volume in the biological cycle from 63.5 to 114.3 t/ha. The yield of phytomass in a crop rotation, different in structure and set of crops, was as follows: for four-field and five-field crop rotation - 63.5-86.7 t/ha, six field - 89.4, seven-field - 96.9, and eight-field - 114.3 t/ha. The optimization of the ratio of grain, technical and fodder crops allowed us to regulate quantitative parameters of crops’ phytomass, which was alienated from agrocoenosis. The yield of the main products, alienated from the field was, as follows: in four-field crop rotation -20.7 t/ha, five-field - 26.6, six-field -37.8, seven field -28.4 and eight field - 41.3 t/ha, which was 32.6%, 30.7%, 42.3%, 29.3% and 36.1%,respectively. The rest returned to the soil with by-products and crop remains. The total amount of nutrients (NPK) in the phytomass, involved in the circulation, was within the range for four-field crop rotation (100% of grain crops) – 1.814 kg/ha, five-field (80% grain and 20% technical) – 2.368 kg/hectare, six-field (66.8% of cereals, 33.2% of technical ones) - 2,599 kg/ha, seven-field (57.2% of cereals and 42.8% of technical) - 2.956 kg/ha, eight-field (62.5% of cereals, 25.0 % of technical, 12.5% of fodder) –3.491 kg/ha.

Published: December 2019

The article shows morphometry of large and small lateral osteoderms on the Nile crocodile body, which forms into arc-like lines. Length of large lateral osteoderms is 2.52 times greater than small lateral osteoderms, width of large lateral osteoderms is 2.20 times greater than small lateral osteoderms, and area of large lateral osteoderms is 5.59 times greater than small lateral osteoderms. Configuration index (length to width ratio) is similar in large (2.03 ± 0.06) and small (1.92 ± 0.17) lateral osteoderms, but scale range of this factor is less significant in large lateral osteoderms (1.67–2.50), than in small lateral osteoderms (1.00–3.00).

Digestibility of the feed nutrients and the chemical elements balance in broiler chickens were studied under use of mixed feed with sulfate and Zink-mixed ligand complex in the physiological experiment that was conducted in the vivarium of the Bila Tserkva National Agrarian University. A tendency to increase the level of feed nutrients digestibility in the experimental groups of broiler chickens consuming mixed fodders with Zinc-mixed ligand complex was revealed in the conducted experiment. The nutrients digestibility indices were the highest in the chickens of the experimental group 3 where Zink-mixed ligand complex was added to the mixed feed. 45, 37.5 and 30 g of the element was added per 1 ton of mixed feed, respectively, for the growing period of 5-21, 22-35 and 36-42 days. The protein digestibility in this group was 89.2, fat - 82.5, fiber - 12.9 and Nitrogen free extractive substances (NFES) - 83.8%. The lowest digestibility indices of the nutrients were in the control group chickens, which, depending on the age, consumed feeds added with Zinc sulfate at doses corresponding to the introduction of 60, 50, and 40 g of the element per 1 ton of feed - 60.8, 80.2, 11.27, and 82.2%, respectively. Indicators of Nitrogen, Calcium, Phosphorus, and Zinc deposits in the body were also higher in the chicks of the experimental group 3 consuming the feed with Zink-mixed ligand complex. Feeding the birds with Zinc-mixed ligand complex as a component of mixed feed, in comparison with sulfate, improves the nutrients digestibility and increases the amount of chemical elements deposited in the body, which makes it possible to reduce the dose of the additive.

The method of biomonitoring of natural reservoirs by diagnosing early violations in the most sensitive components of hydrobiological groups has been proved. Morphometric parameters of the liver of the family Cyprinidae fish are used as biotest-system for ecological analysis.Taking into account morphometric indexes of fish internal parenchymatous organs, the possibility of predicting the toxic substances influence on the aboriginal ichthyofauna state, has been determined. It has been established that protoplasmic and hemolytic toxicants violate cellular metabolism, causing dystrophy of liver cells in fish. Morphoanalysis of the parameters of the liver of the family Cyprinidae fish, as the most widespread object of the ichthyofauna, is used as the basis for indicating in the system of biomonitoring of the water environment quality to the action of external factors and timely prevention of existing danger.The results obtained serve as the basis for the development of environmental measures to assess and optimize the ecological conditions for the conservation of biological diversity of the ecosystem.
