Testing of Frequency Synthesizers for ZigBee Transceivers
Authors: Hameed Sameed
Published: March 2021

ZigBee is a wireless standard defined for low data rate applications with ultra-low power requirements. Devices based on this standard are expected to be low cost with a large battery life or use energy harvesting techniques.As a part of a major project for developing a fully functional RF transceiver chip complying with the standard, frequency synthesizers have been designed based on integer-N phase lock loops which are expected to work as local oscillators for both the transmitter and the receiver. The standard required the PLLs to be programmable to 16 channels in the 2.4-2.5 GHz range. One of the PLLs used an LC VCO while the other used a ring VCO. This work was meant to test these PLLs to make sure that they met the specifications required of them as per the standard.
Lower emotional awareness is associated with greater early adversity and faster life history strategy
Authors: Smith Ryan , Steklis Horst Dieter , Steklis Netzin , Weihs Karen , Allen John JB , Lane Richard D.
Published: March 2021

Recent theoretical work suggests that emotional awareness (EA) depends on the harshness/predictability of early social interactions – and that low EA may actually be adaptive in harsh environments that lack predictable interpersonal interactions. In evolutionary psychology, this process of psychological “calibration” to early environments corresponds to life history strategy (LHS). In this paper, we tested the relationship between EA and LHS in 177 (40 male) individuals who completed the levels of emotional awareness scale (LEAS), Arizona Life History Battery (short form: K-SF-42), and two measures of early abuse/neglect. Significantly lower EA was observed in those with faster LHS and who had experienced greater early adversity. Notably, LEAS was associated with differences in 1) general reflective cognition, and 2) emotional support from parents during childhood. This suggests that EA may be learned during development based on the benefits of cognitive reflection in environments with different levels of harshness and social predictability.
On the Temporal Nature of Parental Burnout: Development of an Experience Sampling Methodology (ESM) Tool to Assess Parental Burnout and Its Related Ever-Changing Family Context

Published: March 2021

Parental burnout is a growing subject of research, but thus far this research has not examined whether the features of parental burnout fluctuate over time. Moreover, parenting and parental burnout are inextricable from their family context. Therefore, a critical next step involves examining how parental burnout features temporally unfold and interact with the ever-changing family environment. To do so, we developed an 11-item experience sampling methodology (ESM) tool to measure self-reported parental burnout features (specifically emotional exhaustion, emotional distance, and feeling fed up), as well as partner relationship, children’s behavior, behavior toward children, social support, and perceived resources. We conducted two two-week periods of ESM data collection (one with French-language ESM items; n = 9; one with English-language ESM items; n=23) and one eight-week data collection with the French-language ESM items (n=50). We collected the ESM data using formr, an open-source platform, and we provide open access to all materials (including a formr template, allowing free use of the assessment tool), analysis code, and data: https://osf.io/s2yv5/. Participants’ responses indicated sufficient within-person variability (assessed via intraclass correlation) and support for convergent and discriminant validity (assessed by correlating aggregated ESM responses with retrospective questionnaire scores on parental burnout, depression, anxiety, and stress). Lastly, we found that the three parental burnout ESM items had high between-subject reliability and moderate within-subject reliability. Participating parents found the ESM survey easy to answer and not burdensome. Finally, we discuss how assessing parental burnout over time can help usher parental burnout research and treatment forward.
TAKING STOCK: A META-ANALYSIS OF THE EFFECTS OF FOREIGN LANGUAGE ENJOYMENT
Authors: Botes Elouise , Dewaele Jean-Marc , Greiff Samuel
Published: March 2021

Studies examining the positive emotion of foreign language enjoyment (FLE) have recently increased exponentially, as researchers are applying the tenets of positive psychology in applied linguistics. It is therefore an appropriate time to take stock of the current literature and conduct a preliminary meta-analysis. The relationships between FLE and four variables, namely, foreign language anxiety (FLA), willingness to communicate (WTC), academic achievement, and self-perceived achievement were examined. A total of k = 97 effect sizes were analysed with an overall sample size of N = 28,166 in random-effects models with correlation coefficients. There was a moderate negative correlation between FLE and FLA. In turn, moderate positive correlations were found between FLE and WTC, FLE and academic achievement, and FLE and self-perceived achievement. These positive associations confirm the value of FLE in FL learning and further affirm the need for researchers to include positive psychology constructs in the foreign language classroom.
Prospective and hybrid alternative of renewable energy for a sustainable mining
Authors: PEREZ ISRAEL MALLMA , VÁSQUEZ LITA SALAZAR
Published: March 2021

The mining is an energy-intensive industry that requires a stable source of electricity. With the increase in demand for minerals and the decrease in grades, the demand for energy is expected to increase by 36% by 2035. This increased demand relies on the use of fossil fuels since the electricity produced and purchased in the mining companies is Based primarily on fossil fuels, the costs of solar and wind energy storage systems have fallen on an unprecedented scale, encouraging mining companies to test these technologies. Among the influencing factors of the use of renewable energy, is the benefit to the community in the stage of operation and closure or post-closure of a mining project, the next factor is the profile of electricity consumption or demand is important for the calculation of its storage or not, of the renewable energies to be used. As a third factor is the calculation for consumption in the processes. The penetration ranges will determine if its energy storage is possible, and if it is possible to use hybrid control (solar - wind), for this the use of digital tools such as the Holmer program is important, it is an important tool that technical and economical. The government must have a perspective that helps on regulatory issues necessary to promote renewable energy projects with different incentives and interests according to the mining context.
Interventions for Softening Can Lead to Hardening of Opinions: Evidence from a Randomized Controlled Trial
Authors: Spitz Andreas , Abu-Akel Ahmad , West Robert
Published: March 2021

Motivated by the goal of designing interventions for softening polarized opinions on the Web, and building on results from psychology, we hypothesized that people would be moved more easily towards opposing opinions when the latter were voiced by a celebrity they like, rather than by a celebrity they dislike. We tested this hypothesis in a survey-based randomized controlled trial in which we exposed respondents to opinions that were randomly assigned to one of four spokespersons each: a disagreeing but liked celebrity, a disagreeing and disliked celebrity, a disagreeing expert, and an agreeing but disliked celebrity. After the treatment, we measured changes in the respondents' opinions, empathy towards the spokespersons, and use of affective language.Unlike hypothesized, no softening of opinions was observed regardless of the respondents' attitudes towards the celebrity. Instead, we found strong evidence of a hardening of pre-treatment opinions when a disagreeing opinion was attributed to an expert or when an agreeing opinion was attributed to a disliked celebrity. We also observed a pronounced reduction in empathy for disagreeing spokespersons, indicating a punitive response. The only celebrity for whom, on average, empathy remained unchanged was the one who agreed, even though they were disliked. Our results could be explained as a reaction to violated expectations towards experts and as a perceived breach of trust by liked celebrities. They confirm that naive strategies at mediation may not yield intended results, and how difficult it is to depolarize---and how easy it is to further polarize or provoke emotional responses.
Online measures of looking and learning in infancy
Authors: Smith-Flores Alexis Sierra , Perez Jasmin , Zhang Michelle H. , Feigenson Lisa
Published: March 2021

Infants in laboratory settings look longer at impossible than possible events, learn better about objects that behave surprisingly, and match people’s utterances to the objects that likely elicited them. The paradigms that reveal these behaviors have become cornerstones of research on preverbal cognition. But less is known about whether these canonical behaviors generalize in naturalistic environments. Here we describe a series of online protocols that replicate classic laboratory findings, detailing our methods throughout. In Experiment 1, we found that 15-month-olds (N = 24) looked longer at an online impossible support event (an object appearing to defy gravity) than a possible support event. These infants did not, however, show the same success with an online solidity event. In Experiment 2, we found that 15-month-olds (N = 24) showed surprise-induced learning online—they were better able to learn a label for a novel object when the object had just behaved unexpectedly. Finally, in Experiment 3, we found that 16-month-olds (N = 20) who heard a valenced utterance (“Yum!”) showed preferential looking to the object most likely to have generated that utterance. Together, these results suggest that, with some adjustments, testing infants online is a feasible and promising approach for cognitive development research.
Income shock increases delay discounting independently of emotion
Authors: Blain Bastien , Globig Laura K. , Sharot Tali
Published: March 2021

How to distribute resource consumption over time is a critical optimization problem. If an agent were to consume all available resources, they would be left with insufficient resources in the future. Inversely, if an agent were to save all their resources for later, they might not live long enough to consume them. The first error is common due to “temporal discounting” - the tendency to value immediate rewards over equivalent future rewards. A major research goal is to identify the factors that influence the temporal discounting rate, so that policy makers could develop interventions to correct for imbalance. It has been shown that a negative change in life circumstances, such as loss of income, is associated with an increase in temporal discounting. Interestingly, negative affect is also associated with increased temporal discounting. Here, we test whether both negative income shock and negative affect lead to greater temporal discounting, and whether they do so independently. We tested 1,145 individuals as the market was crashing in late March 2020 and unemployment rising due to the COVID-19 crisis and then retested 200 individuals as the market was recovering in June 2020. We found that income shock was strongly related to an increase in delay discounting using cross-sectional and longitudinal data. Importantly, this relationship was independent of the negative impact on affect. These findings suggest that the link between income change and delay discounting is a direct result of liquidity constraints, not of changes in affect. This independence may be adaptive, as affect is a noisy reflection of environmental constraints, which may introduce noise to the decision problem leading to suboptimal choice.
The Insulating Function of Sleep for Well-being: Daily Sleep Quality Attenuates the Link between Current Affect and Global Life Satisfaction
Authors: Willroth Emily C , Gatchpazian Arasteh , Thai Sabrina , Lassetter Bethany , Feinberg Matthew , Ford Brett Quaid
Published: March 2021

Transient affect can be tightly linked with people’s global life satisfaction (i.e., affect globalizing). This volatile judgment style leaves life satisfaction vulnerable to the inevitable highs and lows of everyday life, and has been associated with lower psychological health. The present study examines a potentially fundamental but untested regulatory role of sleep: insulating people’s global life satisfaction from the affective highs and lows of daily life. We tested this hypothesis in two daily diary samples (N1=3,011 daily diary observations of 274 participants and N2=12,740 daily diary observations of 811 participants). Consistent with preregistered hypotheses, following nights of reported high-quality sleep, the link between current affect and global life satisfaction was attenuated (i.e., lower affect globalizing). Sleep-based interventions are broadly useful for improv-ing psychological health and the current findings suggest another avenue by which such interventions may improve well-being: by providing a crucial protection against the risks associated with affect globalizing.
How to Motivate and Engage Generation Clash of Clans at Work? Emergent Properties of Business Gamification Elements in the Digital Economy
Authors: Dacre Nicholas , Constantinides Panos , Nandhakumar Joe
Published: March 2021

Organisations are currently lacking in developing and implementing business systems in meaningful ways to motivate and engage their staff. This is particularly salient as the average employee spends eleven cumulative years of their life at work, however less than one third of the workforce are actually engaged in their duties throughout their career. Such low levels of engagement are particularly prominent with younger employees, referred to as Generation Y (GenY), who are the least engaged of all groups at work. However, they will dedicate around five cumulative years of their life immersed playing video games such as ‘Clash of Clans’, whether for social, competitive, extrinsic, or intrinsic motivational factors. Using behavioural concepts derived from video games, and applying game design elements in business systems to motivate employees in the digital economy, is a concept which has come to be recognised as Business Gamification. Thus, the purpose of this research paper is to further our understanding of game design elements for business, and investigate their properties from design to implementation in gamified systems. Following a two-year ethnographic style study with both a system development, and a communication agency largely staffed with GenY employees, findings suggest properties in game design elements are emergent and temporal in their instantiations

The study presents the process of developing the structure of territorial self-government in Poland during 1990 to 2000, with a particular consideration of the self-government’s organs, the course of their formation and the rules of their functioning. It should be emphasized at this point that new acts on self-government of 1998 referred in their regulations to many solutions adopted back in 1990 in the act on community self-government, yet in some cases introducing entirely different regulation or only slightly similar to the one in force in community. On the other hand, some regulations adopted in the county legislation became a starting point to the amendment of the act on community self-government. However, in some cases, there occurred differentiation of the constitution of particular units of territorial self-government which was removed by subsequent amendments of legislation in force.
Competency-Based Evaluation Education: Four Essential Things to Know and Do
Authors: Poth Cheryl , Searle Michelle
Published: March 2021

Abstract: Evaluator education must provide robust opportunities to support and assess the progressive, lifelong development of relevant knowledge and skills. If we wish to keep pace with the increasingly complex contexts in which evaluators operate, we need to better align our educational approaches with the global movement toward practice competencies guiding the profession. Key among the challenges is the lack of instructional guidance specific to a competency-based approach to evaluator education. In this practice note, we orient readers to the value of competency-based evaluation education and describe the teaching context using a systems perspective to examine the dynamic learning interactions and experiences. We advance four essential instructional features of the competency-based approach revealed by a study documenting the impacts on learning and student experiences. We conclude with lessons learned from reflecting upon our experiences during the development and implementation of a competency-based doctoral-level evaluation course to highlight the mutual benefits for learners and instructors.
Collaborative Evaluation Designs as an Authentic Course Assessment
Authors: Searle Michelle , Poth Cheryl
Published: March 2021

Abstract: Strategies for optimizing evaluator education involve ongoing discussions within the field of evaluation. There remains unrealized potential for authentic assessments to support and measure learning that demonstrates the integration of evaluation theory with practice. In this practice note, we advance collaborative evaluation designs as a useful authentic assessment for generating the type of applied learning evidence required within an evaluation-focused graduate course. First, we provide a brief review of educational literature, highlighting the value of authentic assessments and a description of the contexts where we effectively applied the collaborative evaluation design. Next, we offer details of the four instructional processes involved in the authentic assessment: planning, development, feedback, and measurement. Finally, we advance lessons learned from our instructional experiences and the learner benefits of the collaborative evaluation design as an authentic assessment.

Published: March 2021

Abstract: In this practice note, two international students of evaluation reflect on the cultural challenges they experienced learning to apply Western-based methodologies in unfamiliar cultural contexts. Using a process of reflection, the students identify four interrelated challenges: understanding the culture and program setting, the need for interpersonal and communication skills, learning the language of evaluation, and telling the story. The paper concludes with reflections from the course professor, who highlights the challenges of teaching evaluation, an intensely cultural practice with deep roots in Western theoretical traditions, to students who do not come from the United States. Through reflective practice, the two students were able to overcome many of their initial challenges.
Interaction Increasing Factors: Research on E-learning Content Design
Authors: SOYDAŞ ÇAKIR Hülya , AKYAZI Erhan
Published: March 2021

Interaction is one of the key elements for learning and it also has a significant role in increasing efficiency in e-learning programs. Several studies indicate that high level of learner and content interaction provided by e-learning programs brings learner satisfaction and achievement. During the learning process, content interaction provides an effective means to reach learning goals. Successful content design and adequate content interaction items are essential to sustain attention, provide motivation, achieve high levels of satisfaction of learning and provide significant increase in learning performance. In this study, perception and expectation of 236 e-learners are examined to observe the outcomes of content design in learning. The items required for content interaction are classified under three main topics as Attention-Motivation, Satisfaction and Learning Performance. The research model is based on how efficient design of these items helps to increase learner and content interaction. The increase of interaction will result in learner achievement. Therefore, the efficiency of the e-learning process will correlate with higher levels of learner-content interaction. Adequate and efficient content design contributes to effective learning.

Protest Voting dan Abstention dalam Pilkada Calon Tunggal: Kasus Pilkada Serentak 2018
Authors: Mahpudin Mahpudin
Published: March 2021

Tulisan ini membahas tentang dinamika partisipasi pemilih dalam konteks pemilihan kepala daerah dengan satu pasangan calon. Politik elektoral yang hanya diikuti oleh satu pasangan calon menyebabkan munculnya kotak kosong untuk memastikan kontestasi tetap ada. Kotak kosong menjadi pilihan alternatif bagi pemilih yang tidak puas dengan calon atau kecewa dengan kondisi politik yang ada. Karena itu, dalam setting pemilu lokal dengan calon tunggal telah memunculkan fenomena protest voting dan abstenstion. Saya berargumen bahwa meskipun mayoritas daerah dimenangkan oleh pasangan calon, tetapi apabila dianalisa lebih detail, kemenangan pasangan calon pada beberapa daerah tidak signifkan dibandingkan dengan presentase perolehan suara akumulasi dari protest voting dan abstention. Hal ini merefeleksikan bahwa tidak semua pasangan calon yang menang ditopang oleh basis legitimasi yang kuat.
THE IMPORTANCE OF LUPINE IN FOOD SECURITY
Authors: Gaponov N. V.
Published: March 2021

A method for solving the problem of protein and energy value of rations is presented, which seems to be a key task for workers in animal husbandry and agricultural science. An important place in it is given to legumes and oilseeds. They are widely used in feeding animals in the form of green fodder, natural, crushed seeds and products of their processing (cake, meal, oil, etc.) and, to a limited extent, in the composition of compound feed. A key issue in feed production is the problem of feed protein. The further development of animal husbandry depends on its solution. Protein deficiency in rations is usually up to 30%, and this leads to overconsumption of feed and increases the cost of livestock products by 1.5–2.0 times. The solution to the problem of fodder protein should be carried out mainly at the expense of leguminous crops and their mixtures, legumes. One of the main tasks of fodder production is the introduction of progressive harvesting techniques. Dry feed mixtures with their structure and shape most fully meet the physiological needs of animals due to the increased energy of nutrients and product quality.

The modern food industry offers the consumer bread baked with sourdough using various biologically active components of plant origin. In the production of yeast-free bread, it is advisable to use a sourdough from biologically active strains of Streptococcus thermophilus selected by the Gorsk State Agricultural University. The authors have compiled a starter culture from local strains of lactic acid microorganisms selected by the Research Institute of Biotechnology of the Gorsky State Agrarian University. Research was carried out at the Department of Biological and Chemical Technology of the Gorsky State Agrarian University. We also used cones of wild-growing hops from the botanical garden of the Gorsky State Agrarian University in order that the bitter acids present in the hops suppress the putrefactive microflora, do not have a detrimental effect on local strains of lactic acid microorganisms and allow increasing the productivity of the hop starter culture. Yeast-free bread is easily absorbed by the body, does not harm the intestinal microflora, retains useful properties during storage. The flour used in the experiment met the requirements of GOST 26574–85. When using wild-growing hops in the production of bread, useful substances included in its composition were determined that could increase the quality and safety of bread. The content of alpha acids was 6.0%, and that of essential oils was 0.7%, which corresponds to GOST 32912–2014. We used two strains of a lactic acid microorganism of local selection – Streptococcus thermophilus. Hops were extracted for 30 min at a temperature of 96 °C. Laboratory baking of bread was carried out in accordance with GOST 27669–88. Studies have shown that bread prepared using a local strain of Streptococcus thermophilus selected by the Gorsky State Agricultural University and wild-growing hops is of high quality.

Published: March 2021

Confectionery - food products, usually with a high sugar content, characterized by high calorie content and digestibility. They are divided into groups: sugar, flour confectionery, chocolate, cocoa. The following types of products are used as the main raw materials for the preparation of confectionery products: flour (wheat, rye, corn, rice, oatmeal, etc.), sugar, honey, fruits and berries, milk and cream, fats, eggs, yeast, starch, cocoa, nuts, food acids, gelling agents, flavoring and aromatic additives, food dyes and baking powder. The high content of carbohydrates, proteins and fats, as well as polyunsaturatedfatty acids and some vitamins determines the significant value of confectionery products. The influence of shelf life on biscuit semi-finished products prepared according to the classical recipe using pomace powder and concentrated juice of black currant and blueberry berries is shown. Methods used in the experimental part: measurement of the total phenolic content using the Folin-Chekelau reagent, the total content of flavonoids and anthocyanins, the level of free radical capture DPPH (2,2-diphenyl-1-picrilhydrazyl), the total antioxidant activity by the FRAP method and the antioxidant activity in the linoleic acid system. It was found that the content of phenolic substances, flavonoids, anthocyanins and antioxidant activity is greatly influenced by high humidity and a constant light source. These indicators are significantly reduced, but when stored in a vacuum, this decrease in indicators can be slowed down.

Ippolit Bogdanovič, a Court Translator of Catherine II: An Episode from His Biography of “The Lyre” Period (1773)
Authors:   News agency “Fergana”, Osokin Mikhail Yu.
Published: March 2021

Bogdanovič’s humble petition of 1773 to the Empress Catherine II, where the poet reminds about his diligent services and askes to help him with clearing his 3000 ruble debt. His translations of poems devoted to Catherine II by Michelangiolo Gianetti and by Jean-François Marmontel (the latter poem was inspired directly by the Imperial Court) gave him the moral right for this request. Bogdanovič shortened Marmontel’s poem by half and edited what was left. The autocracy criticism was transformed into lamentations on the lack of artistic freedom, which, in turn, was mitigated by the translator’s note. Moreover, the text was placed in panegyric context in Bogdanovič’s collection of poems “Lira” (1773) along the line with the translations of eulogistic poems to Catherine The Great by Voltaire and Michelangiolo Gianetti, an Italian doctor who did not seem to have any wish to lecture monarchs. 1000 rubles, which Bogdanovič had received, can be seen as a payment for this job. This collaboration allows us to revise the prevailing outlook on Bogdanovič’s creative evolution as a history of compromises of “latent oppositionist” with a “secret liberty of beliefs” from the circle of the Count Nikita Panin.
Design of Electronic Moxibustion Instrument for Umbilical Therapy and Preliminary Analysis of Temperature Field

Published: March 2021

Moxibustion has a history of thousands of years. Umbilical moxibustion achieves prevention and treatment of diseases through moxibustion at the golden section of the human body-the umbilicus. It has enough clinical practice experience. Traditional treatment methods have problems such as irritating smoke, uncontrollable temperature, experience-based, and difficult to quantify. Based on the principle of traditional umbilical moxibustion, a structural design of an electronic smokeless umbilical moxibustion instrument is proposed, which belongs to indirect moxibustion and has the advantages of smokeless, electric heating, portability, temperature monitoring and controllability. The internal heat transfer process of the moxibustion instrument is mainly heat convection and heat radiation. Based on ANSYS software, the internal temperature field of the moxibustion instrument is analyzed, and the steady-state temperature distribution and the temperature change characteristic curve of different positions with time are obtained to verify the rationality of the structural design. At the same time, lay a research foundation for the measurable and quantifiable effects of moxibustion on umbilical therapy.
Improving Electricity Production in Solar Chimney Power Plants with Sloping Ground Design: An Extensive CFD Research
Authors: Pinar Mert Cuce  , Erdem Cuce  , Harun Sen
Published: March 2021

Unlike other solar energy systems, solar chimney power plants (SCPPs) allow power output even when there is no sun. SCPPs are promising with their simple structure and 24-hour electricity production potential. Massive pressure tower in the system maintains continuous energy generation irrespective of climatic conditions. Solar energy harnessed by the huge collector area is transmitted to the gorund material for sensible or latent heat storage purpose, and this stored energy during daytime yields to enhanced thermal and buoyant effects even after sunset. SCPPs are also in the centre of interest owing to their eco-friendly operation not causing any CO2 emission. Design aspects in SCPPs are widely studied numerically by researchers. However, geometric design factors are merely analysed for collector and chimney, and very few attempts are done for the ground design. In the present work, a new design for ground is proposed in order to improve the energy stored in the ground material, and the upward movement of the air flow in the system from collector to chimney by changing the ground geometry. The upward movement of the air under the collector is enhanced with the new design created by inclining the ground at a distance of 21 m from the chimney inlet to a certain distance from the collector inlet. ANSYS WORKBENCH based CFD analysis is carried out based on the geometric dimensions of the Manzanares pilot plant. Analyses are based on a 90° 3D CFD model for the purpose of time saving in iterations. The CFD model is supported by RNG k-? turbulence and DO (discrete ordinates) solar ray tracing models. After CFD results are verified with the experimental data, simulations are repeated for different designs and the ideal design is achieved. It is observed that the maximum air flow velocity, which is 14.202 m/s on the horizontal ground for the reference case, is improved by 34.1% in the new design to 19.046 m/s. In addition, it is seen that the power output of the reference case (54.333 kW) is enhanced by 23.04% to 66.855 kW.

A presente pesquisa visa responder ao dilema de como se conciliam a arbitragem e a jurisdição estatal no contexto brasileiro. Por meio de uma reflexão sobre a arbitragem e as fronteiras que a circundam, impõe-se o questionamento quanto aos limites e às possibilidades da interferência judicial no processo arbitral. Estruturou-se a produção em três tópicos de análise, sendo estes: o controle judicial sobre a jurisdição arbitral; a complementariedade entre as jurisdições arbitrais e estatais; e, as relações entre a arbitragem e o Poder Judiciário. Como método de abordagem, aplicou-se o dedutivo. Como método de procedimento, empregou-se o monográfico. Observou-se como fundamental a busca pelo equilíbrio harmônico entre a arbitragem com o devido processo legal. Sendo assim, verificou-se que a arbitragem não pode ser avaliada por um viés de absoluta independência do Poder Judiciário, tendo em vista que cabe à jurisdição estatal prestar o devido suporte e assistência ao processo arbitral.
The possibility of using tiletamine-zolazepam for sedation during oral administration in dogs and cats: literature review
Authors: Kornyushenkov Evgeniy , Shimshirt Aleksandr
Published: March 2021

The review presents the results of three studies of the use of tiletamine-zolazepam for sedation during oral administration in dogs and cats. Study 1. Objective: to study the sedative effect of the combination of tiletamine-zolazepam-acepromazine (TZA) or ketamine-flunitrazepam (CF) in dogs with oral administration, as well as to evaluate the effectiveness of the capsule form of TZA in stray dogs. In a pilot study, 6 dogs were administered a liquid form of TZA (20 mg/kg tiletamine-zolazepam and 2 mg/kg acepromazine) or a liquid form of CF (50 mg/kg ketamine and 2 mg/kg flunitrazepam) orally. Sedation was evaluated in points. On average, the time interval from the introduction of MAL to the adoption of the animal side position was: protocol 1 (infusion of the drug into the mouth) — 47.5 (35...80) minutes (67 % of dogs); protocol 2 (addition of the capsule form to the canned food) — 30 (15...65) minutes (83 %), protocol 3 (addition of the liquid form of the drug in gravy) — 75 (45...110) minutes (100 %). None of the dogs in the CF group in protocols 2 and 3 took a side position. Based on these results, 20 stray dogs received encapsulated MAL: TZ (20 mg/kg) and acepromazine (2 mg/kg). Overall, 63 % of the stray dogs in the experiment were caught after eating a double dose of MAL. Oral administration of encapsulated MAL added to the canned food allows you to catch stray dogs, but it may require the use of additional drugs. The time from the introduction of TZA to the development of sedation in animals and the taste of the drug affect the percentage of capture. Study 2. The purpose of the study is to study the possibility of oral administration of the drug «Zoletil» to cats. 8 healthy cats, females and males, aged from 2 to 4 years, were selected. «Zoletil-50» was used in the form of a sterile lyophilizate prepared in the form of a solution with water for injection in doses from 15 to 25 mg/kg. After administration of the drug, hemodynamic parameters, sedation, and the possibility of endotrachial intubation were evaluated. After oral administration, the effect of sedation developed quite quickly. When administered at a dose of 25 mg/kg, intubation and minor surgical interventions were possible. A dose of 15 mg / kg caused only sedation. It is advisable to use «Zoletil» in the form of a powder with a pleasant taste. Study 3. Objective: to assess the quality of sedation, changes in SAD, heart rate and BH in TB administration of TK to healthy cats. Healthy, sterilized European shorthair cats (n=7; 3 males, 4 females) were included in a randomized, blind, cross-sectional study. Each cat received two doses of tiletamine-diazepam TB: 5 mg / kg (LD) and 7.5 mg/kg (HD) of each drug. TB administration of tiletamine-zolazepam in the studied doses is a simple and effective method of pharmacological fixation of cats, while LD has less effect on SAD and BH than HD.

Quercetin as a precursor in the synthesis of analogues of fulvic acids and their antibacterial properties
Authors:   The Bohdan Khmelnytsky National University of Cherkasy, Litvin V.A. , Njoh R.A. ,   Near East University
Published: March 2021

A simple, fast and effective method for producing synthetic substances with properties similar to natural humic substances has been proposed. The synthesis method is based on the oxidation of quercetin by molecular oxygen in an alkaline medium, followed by conversion to the acid form by passing through a cation exchange column. Study of elemental and functional compositions, spectral properties (UV/Vis and IR range) and redox characteristics allowed qualifying the resulting product as a synthetic fulvic acid. The enhanced antibacterial properties of the obtained synthetic product were established. The minimum concentration of inhibition of synthetic fulvic acid derived from quercetin is 25 g mL–1, which is in 100 times less than for natural humic substances.

Land conversion activities cause changes in the area of vegetation and carbon storage in the air. These changes can lead to emissions (reduction of carbon stocks) or sequestration (addition of carbon stocks). This study aims to calculate stored carbon in the Padang watershed in 2009 and 2019 and to determine the dynamics of emissions and carbon sequestration due to land conversion in the Padang watershed, North Sumatra Province from 2009 to 2019. The method used in this research is spatial data processing using software Arc Gis. Processing, interpretation and classification of land cover are obtained from land cover data for 2009 and 2019 from the Ministry of Environment and Forestry. Furthermore, the analysis of emissions and carbon sequestration in the Padang watershed was carried out using the REDD Abacus SP software. The results showed that the total carbon stored in 2009 was 5,168,464.09 tons. Meanwhile, the total carbon stored in 2019 was 5,150,784.81 tons. This means that there is a decrease or carbon emission during the 2009-2019 period of 17,679.28 tons. The total net emissions and sequestration that occurred in the Padang watershed due to changes in land use from 2009 - 2019 were 22,851,751.43 tonnes CO2-eq / year and  3,100,199.00 tonnes CO2-eq / year, respectively. Efforts to reduce emissions include planting and developing forests and community-based forest management.
