Identification of a 50-year scaling relating current global energy demands to historically cumulative economic production
Authors: Garrett Timothy J. , Grasselli Matheus R. , Keen Stephen
Published: April 2021

Abstract. Global economic production, or the GDP, has risen steadily relative to world primary energy demands, suggesting technological change is driving a gradual decoupling of society from its resource needs and associated pollution. Here show that in each of the 50 years following 1970 for which reliable data are available, one Exajoule of world energy was consumed to sustain each 5.50 ± 0.21 trillion constant 2019 US dollars, not of yearly production or physical capital, but of running cumulative production summed over human history. The half-century for which this fixed ratio held covers two thirds of historical growth in energy demands, so assuming its persistence, the implication is that society is not in fact decoupling from resource needs. Rather, it can be expected that future environmental impacts will be more strongly guided by past activities, or inertia, than is generally permitted within economic and climate modeling prescriptions that allow for policy to spur more rapid change.
Review article: State-of-the-art trajectory tracking of autonomous vehicles
Authors: Li Lei , Li Jun , Zhang Shiyi
Published: April 2021

Abstract. Air pollution, energy consumption, and human safety issues have aroused people's concern around the world. This phenomenon could be significantly alleviated with the development of automatic driving techniques, artificial intelligence, and computer science. Autonomous vehicles can be generally modularized as environment perception, path planning, and trajectory tracking. Trajectory tracking is a fundamental part of autonomous vehicles which controls the autonomous vehicles effectively and stably to track the reference trajectory that is predetermined by the path planning module. In this paper, a review of the state-of-the-art trajectory tracking of autonomous vehicles is presented. Both the trajectory tracking methods and the most commonly used trajectory tracking controllers of autonomous vehicles, besides state-of-art research studies of these controllers, are described.

Published: April 2021

Adult Recurrent Respiratory Papillomatosis (RRP) is a rare disease caused by the human papilloma virus in which papilloma grows from the respiratory epithelium. Patients can suffer from significant respiratory distress secondary to tracheal or bronchial obstruction by papilloma and the mainstay of treatment is bronchoscopic debridement. There are a variety of techniques to resect the endoluminal tumor, including CO2 or YAG laser, argon plasma coagulation, microdebrider and cold forceps. There have been documented cases of healthcare workers contracting HPV after exposure to surgical smoke during ablation of papilloma and measures should be taken to avoid inhalation of the smoke plume. For proximal lesions that are accessible to a microdebrider, this appears to be a safe and effective technique that does not generate heat or surgical smoke.

Authors: Mjw Endrian , Adawiyah Dewi , Supriadi Dedi
Published: April 2021

Latar Belakang : Upaya pencegahan merupakan sebuah usaha yang dilakukan individu dalam mencegah terjadinya sesuatu yang tidak diinginkan. Pelecehan seksual adalah segala bentuk perilaku yang berkonotasi seksual yang dilakukan secara sepihak dan tidak  diharapkan oleh orang yang menjadi sasaran sehingga menimbulkan reaksi negatif: rasa malu, marah, tersinggung dan sebagainya. Menurut data Perlindungan Perempuan dan Anak adanya 29 kasus pelecehan seksual terhadap remaja di Ciamis pada tahun 2017. Alasan peneliti memilih di SMP Negeri 4 Ciamis karena dekat dengan pusat kota dan tempat bermain dan SMP Negeri 4 Ciamis mewakili untuk dijadikan tempat penelitian.

Tujuan : Untuk mengetahui upaya pencegahan pelecehan seksual pada remaja puteri kelas VIII di SMP Negeri 4 Ciamis.

Metode Penelitian : kuantitatif dengan menggunakan desain deskriptif dan rancangan penelitian cross sectional pada 67 responden remaja putri. Jumlah populasi 133 orang, dan pengambilan sampel menggunakan metode kebetulan (accidental sampling) yang diambil dari remaja puteri kelas VIII di SMP Negeri 4 Ciamis tahun ajar 2017/2018.

Hasil Penelitian: kategori upaya pencegahan pelecehan seksual pada remaja puteri kelas VIII di SMP Negeri 4 Ciamis didapatkan upaya baik sebanyak 42 responden (62,7%) dan upaya cukup sebanyak 25 responden (37,3%).

Pembahasan: pemahaman hak-hak pada remaja dengan penyuluhan kesehatan di sekolah menengah pertama akan lebih efektif untuk mencegah pelecehan seksual. Mencegah lebih baik daripada harus melakukan perawatan pada korban pelecehan yang memerlukan tindakan komprehensif dan melibatkan psikososial kultural dimana meskipun korban sembuh tapi akan memberikan trauma yang mendalam.

Kesimpulan : penelitian ini menyatakan bahwa pada 67 remaja puteri yang dijadikan responden memiliki kategori baik dalam pencegahan pelecehan seksual.
Financial education:why do we need it?
Authors: Toledo Adriana
Published: April 2021

For the longest time, roughly from the 16th century, with the establishment of capitalism around the world, people have been working towards ways of ensuring their survival by accumulating assets and money. Capitalism is a system predominated by private ownership and the constant quest for profit and the accumulation of wealth. Despite being conceived as an economic system model, it influences political, social, cultural, ethical and many other spheres, encompassing our affecting our entire nation. With the onset of globalization over the past 50 years, the capitalist system has become the predominant system throughout the world and effects all beings in one way or another. In an effort to generate wealth, many factors influence decisions made within the world of finances, and ignorance of the theme is no longer an option. Financial education is an important discipline in providing citizens the opportunity to exercise their rights and duties within the financial world, allowing for more accurate decision-making. Financial citizenship entails an individual’s ability to make the right choices, exercising their rights and fulfilling the associated duties. It is a concept taken from the term citizenship.

The effectiveness of visual materials in teaching vocabulary to deaf students of EFL
Authors: Gülengül Birinci Fatma , Sariçoban Arif
Published: April 2021

This study aims to investigate the effectiveness of using visual materials in teaching vocabulary to deaf students of EFL. For this purpose, 80 deaf students from a state special education vocational high school in Turkey contributed to this study. All students had first English classes in their lives and they are at the starter level of English, thus pre-test for their English proficiency was not given. The students were randomly divided into two groups to form the experimental group and the control group. 10 vocabulary items per week were taught to the students, and 50 target vocabulary items in total were taught during the whole study. To the experimental group, the vocabulary items were taught via visual materials together with the sign language. The control group was not presented with any visual items during the teaching process of the experiment, only sign language instruction was used for them. After the treatment, a vocabulary test was given to each group as an immediate post-test to measure the impact on learning. Six weeks after the immediate tests, delayed post-test was given to the groups to test long term retention. The results of the two post-tests were analyzed through Independent Samples t-test and Paired Samples t-test calculations to investigate the effectiveness of visual materials. According to the results of the study, visual materials were found to be more effective than using only the sign language that does not contain any visual items in teaching vocabulary items to deaf learners who learn English as a foreign language.
Long-term Photometric Monitoring of FUor and FUor-like Objects
Authors: Semkov E. , Ibryamov S. , Peneva S. , Mutafov A.
Published: April 2021

A phenomenon with a significant role in stellar evolution is the FU Orionis (FUor) type of outburst. The first three (classical) FUors (FU Ori, V1515 Cyg and V1057 Cyg) are well-studied and their light curves are published in the literature. But recently, over a dozen new objects of this type were discovered, whose photometric history we do not know well. Using recent data from photometric monitoring and data from the photographic plate archives we aim to study, the long-term photometric behavior of FUor and FUor-like objects. The construction of the historical light curves of FUors could be very important for determining the beginning of the outburst, the time to reach the maximum light, the rate of increase and decrease in brightness, the pre-outburst variability of the star. So far we have published our results for the light curves of V2493 Cyg, V582 Aur, Parsamian 21 and V1647 Ori. In this paper we present new data that describe more accurate the photometric behavior of these objects. In comparing our results with light curves of the well-studied FUors (FU Ori, V1515 Cyg and V1057 Cyg), we conclude that every object shows different photometric behavior. Each known FUor has a different rate of increase and decrease in brightness and a different light curve shape.

Published: April 2021

With the increase of construction activities in Ghana, there is an increasing demand in building materials leading to the shortage of the conventional materials. The informal sector is gradually seeing the introduction of quarry dust as a substitute of sand in block production. This paper focuses on a comparative analysis of the quality of sandcrete blocks and quarry dust cement blocks. Block samples were gathered from various suppliers around the Prampram and Dawhenya areas and through various laboratory tests were tested for their dimension tolerance, water absorption and compressive strengths. Aggregate samples were also taken from suppliers for sieve analyses. The study revealed that the quarry dust cement blocks contained relatively higher percentages of coarse grade particles compared to the sandcrete blocks. The total average water absorption of sandcrete blocks was found to be 3.90% while quarry dust showed an improved value of 3.28%. Sandcrete blocks were averagely found to be of a higher compressive strength of 4.31N/mm2, with quarry dust at 3.0N/mm2. The study suggested the likelihood of a lesser use of cement in the production of quarry dust cement blocks due to the similarities in colour between the quarry dust and cement, hence, negatively affecting its compressive strength.

Published: April 2021

Significant oil losses in oil-containing wastes and their adverse impact on the region’s environmental setting bring about the need to develop an oil-containing wastes treatment technology. To tackle this issue, the authors have set an aim of designing a helio device and creating an oil-containing wastes treatment method based on it to extract oil products. Considering a wide spread in the composition and properties of potential oil sludge raw materials and their tendency for either formation of stable emulsions or phase separation, we have conducted in-depth modern physical and chemical studies and defined the need to develop a commercial oil-containing wastes purification method. We have designed the device, in which oil product hydrocarbons undergo thermal treatment using solar energy without prejudice to their chemical structure. Following oil-containing wastes purification using solar energy, the particulate load in soil does not exceed 6.65-6.79% and the absolute molecular weight of hydrocarbons approaches that of bitumen. The oil-containing wastes purification method developed solves an important environmental issue of oil-containing wastes recycling, promotes recovery and prevents degradation of natural complexes, and reduces soil and water pollution.

Overgang van onderneming in een triptiek: economische activiteiten, anciënniteit en cao’s

Het arrest Scattolon biedt minimaal drie interessante inzichten ten aanzien van overgang van onderneming. Ten eerste geeft het Hof van Justitie inzicht in de toepasselijkheid van Richtlijn 2001/23 op publieke ondernemingen. Ten tweede wordt de vraag beantwoord in hoeverre anciënniteit een voor overgang vatbaar recht is: de anciënniteit dient gekoppeld te zijn aan bij de vervreemder bestaande rechten. Opmerkelijk is dat het Hof tevens overwoog dat, indien anciënniteit op basis van deze regel niet zou overgaan, niettemin compensatie dient plaats te vinden indien de werknemer er anders substantieel op achteruit zou gaan. Ten slotte is hetgeen het Hof impliciet oordeelt over gebondenheid aan de overgekomen cao van groot belang voor de Nederlandse rechtspraktijk: het direct toepassen van de eigen cao na overgang van onderneming is mogelijk. Het Nederlandse recht is hier niet op berekend. Naar het oordeel van de auteurs ligt hier een taak voor de wetgever.

Het Europese grondrecht van jaarlijkse vakantie: voorwaarden bij ziekte en (horizontale) doorwerking

In deze bespreking van de recente arresten van het HvJ EU over het jaarlijkse vakantierecht met behoud van loon worden twee onderwerpen behandeld. Ten eerste het grondrechtelijk karakter van het vakantierecht, de effecten daarvan voor eventuele directe horizontale werking en de verhouding van dit EU-grondrecht met het vergelijkbare ILO-grondrecht. Ten tweede wordt op basis van de nieuwe Europese jurisprudentie, waarbij het verval van vakantierechten bij ziekte niet langer is uitgesloten, onderzocht of de nieuw ingevoerde Nederlandse vervaltermijn voor vakantierechten niet te kort is.
Verplichte vervroegde pensionering van piloten: leeftijdsdiscriminatie?

Verplichte vervroegde pensionering van piloten: leeftijdsdiscriminatie?

Verplicht vervroegd pensioen is een fenomeen dat weliswaar steeds minder voorkomt, maar voor sommige beroepen nog vrij normaal is. Bij luchtvaartmaatschappijen zoals de KLM, maar daar niet alleen, geldt nog steeds een regeling dat piloten ruim voor de AOW-leeftijd, variërend van 56 tot 60 jaar, met pensioen (moeten) gaan. Er geldt een automatisch pensioenontslag. In 2012 heeft de Hoge Raad zich opnieuw moeten buigen over wat door piloten als leeftijdsdiscriminatie wordt aangemerkt. In 2006 had de Hoge Raad dat ook al eens gedaan in soortgelijke zaken. In de rechtspraak van het Hof van Justitie van de Europese Unie vindt men inmiddels een uitgebreide jurisprudentie op verplicht pensioenontslag. In zijn recente arrest van 2012 volgt de Hoge Raad de lijn van de rechtspraak van het Europese Hof en komt tot de conclusie dat er weliswaar sprake is van ‘onderscheid naar leeftijd’, maar dat daarvoor een objectieve rechtvaardiging bestaat zoals door KLM en de vakbond van piloten was aangegeven. Deze uitspraak is niet alleen van belang voor deze KLM-piloten, maar gaat verder, omdat het verplichte of automatische pensioenontslag, niet alleen ‘vervroegd’ maar ook op latere leeftijd, zoals dat tegenwoordig vaker voorkomt, hier aan de orde is. In deze annotatie wordt de motivering van de Hoge Raad – en van het hof van Amsterdam in appèl – tegen het licht gehouden en geconfronteerd met de wijze waarop het Europese Hof en de hoogste gerechten in Duitsland en Frankrijk te werk gaan. Er kan gerede twijfel rijzen of de redeneringen in de Nederlandse rechtspraak wel even sound en houdbaar zijn als we in de rechtspraak van het Europese Hof en het Duitse Bundesarbeitsgericht aantreffen. De materie is weerbarstig, dat is wel duidelijk. Zij heeft vele facetten, niet in het minst uit een oogpunt van werkgelegenheidsbeleid, landelijk én lokaal of zelfs op het niveau van de onderneming. In deze annotatie worden de verschillende invalshoeken belicht om tot een oordeel te komen óf en zo ja onder welke voorwaarden een dergelijk onderscheid naar leeftijd gerechtvaardigd zou kunnen zijn en welke eisen gesteld zouden moeten worden aan de motivering ervan.

Het nieuwe Wetboek van Strafvordering. Hoe verder?

Het nieuwe Wetboek van Strafvordering bevindt zich in een kritische tussenfase. Er is geld nodig om een volgende stap te kunnen zetten. Het volgende kabinet zal hierover moeten beslissen. Deze bijdrage kijkt naar nut en noodzaak van het nieuwe Wetboek van Strafvordering. Als daar positief over wordt geoordeeld, is een minstens even belangrijke vraag voor het komende kabinet hoe het traject op een kansrijke wijze zou kunnen worden voortgezet.
Herwaardering van de strafrechtadvocaat

Herwaardering van de strafrechtadvocaat

De positie van de strafrechtadvocaat staat echter meer dan ooit onder druk. In de eerste plaats bestaan bij de beroepsgroep grote zorgen om de veiligheid van advocaten en de reputatie van strafrechtadvocaten, die gemakkelijk op het spel wordt gezet. Daarnaast wordt ook aan het professionele verschoningsrecht geknabbeld, zijn de verhoudingen tussen het OM en advocaten verder gepolariseerd en is de financiering van de sociale advocatuur nog steeds niet ‘herijkt’. In deze bijdrage wordt gepleit voor een herwaardering van de rol van de strafrechtadvocaat. Hierbij gaat het vooral om het beeld dat van de strafrechtadvocaat bestaat: is de strafrechtadvocaat louter een sta-in-de-weg in de zoektocht naar de materiële waarheid of kunnen meer betrokkenheid van de advocaat en meer aandacht voor rechtsbescherming juist bijdragen aan een betere en meer efficiënte strafrechtspleging?

De resocialisatie vanuit een ander perspectief

De afgelopen jaren heeft in het gevangeniswezen een aantal ingrijpende veranderingen plaatsgevonden. De detentiefasering is naar de achtergrond verdwenen en detentieregimes zijn versoberd. Dit biedt aanmerkelijk minder aanknopingspunten voor resocialisatie. Beveiliging van de samenleving staat voorop in de omgang met gedetineerden. De veranderingen worden op korte termijn versterkt als de Wet straffen en beschermen in werking treedt. Maar schieten we als samenleving juist niet veel meer op met meer mogelijkheden voor resocialisatie tijdens de detentie? Deze bijdrage schetst een aantal aansprekende ideeën daarover.

Published: April 2021

El libro Conducting Personal Network Research es una introducción conceptual y metodológica al estudio estructural de las redes personales. Forma parte de una serie de monografías recientes que han empezado a sistematizar el conocimiento generado en este ámbito en las últimas décadas (Crossley, Bellotti, Edwards, Everett, Koskinen & Tranmer, 2015; Perry, Pescosolido & Borgatti, 2018). En este caso, los autores han dedicado gran parte de su carrera a la investigación empírica de las relaciones interpersonales, los contextos de interacción y los procesos de integración social de los inmigrantes, junto con otros colectivos en situación de vulnerabilidad. Con esta publicación, toda esa experiencia se ve ahora reflejada en un texto introductorio claro y comprehensivo. Una parte del libro es una combinación de la metodología de encuestas con el estudio de las redes personales. En este contexto, la principal aportación del libro es la sistematización del conocimiento actual sobre la recolección, el análisis y la visualización de las redes personales.

Estudo descritivo, com abordagem quantitativa, delineado pela análise das relações dos profissionais de saúde de uma unidade de Atenção Básica do município do Rio de Janeiro que teve por objetivos identificar a partir do acolhimento as redes sociais dos atores para producão do cuidado na Atenção Básica em Saúde e caracterizar as relações/interações existentes segundo grau de centralidade, proximidade e intermediação. Os dados foram analisados mediante Análise de Redes Sociais (ARS), com a utilização dos softwares Ucinet e Netdraw, que permitiram a construção do sociograma e a geração das métricas da rede. A ARS permitiu compreender a posição dos atores e como as relações entre os mesmos se conformam através do acolhimento. A medida de densidade foi baixa, indicando que nem todos os atores estão em contato direto uns com os outros, trocando informação ou qualquer tipo de recurso, contribuindo para pouca coesão da rede.  Quanto às medidas de centralidade, proximidade e intermediação o estudo traz relevo sobre os atores de nível superior, com exceção dos técnicos de enfermagem. Concluí-se a partir da rede social que o acolhimento dos usuários no campo segue uma dialética já estabelecida, baseada na queixa evidenciada, julgada e na oferta imediata de respostas, quando o esperado para o campo é um cuidado com foco na promoção e prevenção em saúde.

Evaluate the level of creative support of the teaching process of football game tactics
Authors: Duda Henryk , Stuła Aleksander
Published: April 2021

Teaching tactics in team games is a difficult process, because it requires not only the optimal preparation of the player in the physical and physical sphere but above all the deliberate action in the sport.
Situations that arise when playing football, usually require the choice of one of several possible decisions. Not all decisions are optimal. It is on the basis of the optimal decision that you can judge the advantages of the player and then interpret his abilities.
In order to rationally solve a task in the game, the player must have the best knowledge about the effective action, and they also need to use such tactical preparation methods so that the player can consciously and creatively participate in the training process.
The purpose of research
Determine whether modern football clubs are using tactical training based on creative support in teaching football tactics.
Material and methods of testing
The empirical material was collected by anonymous polls conducted among randomly selected football players in two age categories: junior (140 CLJ players and MW leagues) and senior (160 players IV and III leagues). Research in the years 2015 - 2017 was conducted in randomly selected Polish clubs, with the largest number (about 80%) being players in the Małopolskie, Świętokrzyskie, Podkarpackie, Silesian, Opole and Lubuskie voivodships.
Results and conclusions
The analysis of the research results shows that football players in the clubs surveyed are less likely to benefit from the knowledge transfer, which facilitates learning tactics. The reason for this situation is not only due to the limited organizational conditions for rational training but also can have its basis in the competence of trainers. This problem is significant for young players, which can limit not only the smooth operation of the game but also hinder the process of full development of the player.
1). Tactical training dominates traditional forms of instruction that limit the player's conscious participation in the game.
2). Among the trainers there is a low level of knowledge about the use of tactics to help teach the tactics of the game.
3) . In order to make more use of the teaching aids tactics, there is a need to include this learning direction in the training of trainers and football instructors.
4). Base conditions in football clubs limit the use of modern laboratory measures in teaching tactics.
DIFFERENTIATION OF PHYSICAL FITNESS IN POLISH ELITE SPORTS JU-JITSU ATHLETES PHYSICAL FITNESS IN ELITE JU-JITSU ATHLETES

Published: April 2021

Aim
Ju-jitsu athletes are expected to reach the competitive readiness adequate for the demands of tournaments. Apart from technical expertise, one of the aspects of readiness is general and special preparation. This is critical to the athlete's level of achievement since it helps him or her cope with the training load as it is linked to mental preparation and ensures that the athlete uses technical and tactical variants more accurately during a fight. The cognitive aim of this study is to characterize fitness preparation of top athletes from the Polish Ju-Jitsu Association. The practical aim is to identify talented athletes who can become members of national teams participating in international tournaments.
Basic procedures
The study evaluated 29 national ju-jitsu team members in the preparation period (pre-competition mesocycle), who expressed their interest and consent to participate in the experiment. Thirteen of these athletes were listed in the ju-Jitsu International Federation's ranking, including three world medal winners in World Championships in Wrocław, Poland (2016). Thirteen tests of general physical fitness were performed by means of selected tests from the Eurofit test battery, the ICSPFT tests and additional strength tests. Eight special physical fitness tests were also used. The results were described using cluster analysis and comparison of fitness profiles.
Results
The differences between three clusters in general physical fitness were noticeable in performance of pull-ups (1<2 and 2>3 Cluster), the Cooper test ( 1<2 and 1>3 Clusters), the shuttle-run test (1>2 and 2<3 Cluster), sit-and-reach test (2<3, 2<1) Clusters), maximal hand-grip-strength test (1>3 Cluster), Flamingo balance test (1-3 and 2-3 Clusters). In special physical fitness tests, pronounced differences were observed in performance of Speed punches (1>2 cluster), 1/Flexibility Index (1>3 Cluster), Evasive actions (1<3, 2<3 Clusters) and Push-ups (1>2 and 1>3 Clusters). Profiles of three clusters were highly dissimilar.
Conclusions
The athletes studied were characterized by high differences in fitness-related readiness level. Their profiles in three clusters show that some athletes in the national level group match top athletes at the international competitive level in these terms. Analysis of individual profiles allows for effective diagnosis and classification while revealing strengths and weaknesses of fitness preparation of ju-jitsu athletes. Therefore, it should be used for testing and monitoring of modifications over the training cycles. Knowledge of the structure and the data on baseline physical fitness and special fitness in elite athletes may be useful for the development of individual training programs for ju-jitsu athletes.
BMI INDEX AND LEVEL OF DIFFERENT MOTORITY
CHILDREN AND YOUTH KIELCE
Authors: Jopkiewicz Andrzej , Nowak Stanisław Bogdan
Published: April 2021

The Aim: Evaluation of relationships between the level of various motor skills of Kielce children and adolescents and their relative body mass. Material and methods. The research covered 1737 Kielce girls and boys aged 7-16. In the assessment of the BMI index, the Cole classification was taken into account, which is an international standard of the International Obesity Task Force, enabling the evaluation of overweight and obesity in children and adolescents. In the assessment of various motor skills, the tests included in the International Physical Fitness Test were taken into account, namely: long jump from the place, 4x10m swing course, sit down from the back in 30 seconds, run on 50m, right hand grip, torso slope forward. In the statistical calculations, the analysis of variance (ANNOVA) and the NIR test were used.Results. BMI in the Cole classification is a factor strongly differentiating the level of motor skills of girls and boys. It has been observed that overweight and obesity are factors strongly disturbing the motoric efficiency of children and adolescents, causing a decrease in the level of various motor skills (except for flexibility in girls and handshake in both genders).Conclusions. Correct BMI values are associated with better results in different fitness tests, assessing the level of both fitness and adjustment capacities, which demonstrate greater potential for achieving biological potential, both boys and girls.

Published: April 2021

This paper presents a short history of Polish formations protecting the governing bodies of the state, starting from the moment Poland regained independence at the end of the twentieth century. The considerations are presented against the rules and principles of the functioning of the state security system, with particular emphasis on the control subsystem. This paper demonstrates the need to research attitudes to safety in the past, in order to develop and apply effective contemporary solutions. The considerations contained in it also concern the existing threats to the management of state organs. They may contribute to further discussions on the purpose and rules of operation of the formation which is supposed to protect the most important people in the state.

Commonbeans crop is very demanding in nutrients, where nitrogen is the most required by the crop. The nitrogen fertilization recommendations for the Cerrado in Western Bahia are based on recommendations elaborated for the Cerrado conditions in the BrazilianCentral-Westregion, and such recommendations may not be adequate, as the Cerrado in the state of Bahia is predominantly characterized by sandy soils and little rainfall than the otherareas of this biome, showing peculiar characteristics regarding the behavior of nitrogen in the soil. Thus, the objective of this study was to evaluate the effect of nitrogen doses on the morphological characteristics, yield and quality of beans in the common beans crop in the Cerrado in the State of Bahia. The experiment was conducted in the municipality of Barreiras, State of Bahia (BA), in a randomized block design, consisting of five nitrogen doses (0, 60, 120, 180 and 240 kg ha-1) and four replications. The morphological attributes, grain yield and dry biomass and the physical and chemical quality of the grains were evaluated. The data were subjected to analysis of variance and the means were compared by the test of Tukeyat 5% and regression analysis was performed to assess the effects of N doses on the variables. Regarding morphology, the highest nitrogen doses had a positive influence on stem diameter and number of leaves. The maximum efficiency dose was 63 kg ha-1with productivity of 2,889.6 kg ha-1of grains, while the maximum dose of 240 kg ha-1increased the protein content in grains by 46% in relation to the absence of nitrogen fertilization.

Saline stress is a condition that causes changes in physiological performance in several species and even in cultivars of the same species. Thus, this studyaimed to evaluate the physiological performance of black bean cultivars to salt stress. A completely randomized experimental design was used in a factorial scheme with two cultivars (Mataço and BRS Paisano) and five osmotic potentials simulated with sodium chloride solutions (control = 0.0; -0.2; -0.4; -0.6 and -0.8 MPa), in four replications of 50 seeds per treatment. The variables related to germination, first germination count, germination speed index, and shoot length were evaluated. There were significant interactions (p <0.05) for all variables analyzed. In general, it is concluded that the physiological performance of the seeds of black bean cultivars is affected under simulated saline stress by NaCl solution with an osmotic potential below -0.2 MPa.

Rice the main source of energy to maintain the metabolism for almost four billion people worldwide. Riceplants treated with multifunctional microorganisms may be a good wayfor sustainable improvement of crop grain yield. Aimedstudy the effect of types and ways of microorganisms application in tropical lowland rice production, evaluated by biomass production and gas exchange. The greenhouse trial was in a completely randomized design, in factorial scheme 7 x 3 + 1, with four replication. Treatments were the combination of seven microorganisms: Bacillussp. (BRM32109 e BRM32110); Pseudomonas fluorescens(BRM32111); Pseudomonassp. (BRM32112); Burkholderia pyrrocinia(BRM32113); Serratiasp. (BRM32114) and Trichoderma asperellumpool (UFRA.T06 + UFRA.T09 + UFRA.T12 + UFRA.T52), with three forms of application (1. microbiolized seed; 2. microbiolized seed + soil drenched with microorganism at eight and 15 days after sowing (DAS)and 3. microbiolized seed + microorganism spray plant at eight and 15 DAS). Microbiolized seed was the best form of application,which allowed highest instantaneous carboxylation efficiency and yield of biomassproduction in lowland rice. Rhizobcteria BRM32114, followed by BRM32111, BRM32112 and fungi T. asperellumimproved, an average, 17% in instantaneous carboxylation efficiency and 20% in dry shoot biomass production of lowland rice compared to the control plants.

Oneof the factors that can compromise the strawberry culture is theuse of seedlings without phytosanitary quality. The aim of this study was to evaluate the use of three biological products in the production of strawberry cultivars. For this, six cultivars ('Camino Real', 'Festival', 'Oso Grande', 'Albion', 'San Andreas'and 'Camarosa') were selected to receive the following treatments: T1) Onix (2.4 mL) + Qualit (0.6 mL) (Bacillus methylotrophicus+ Trichoderma asperellum); T2) Rhizos (2.4 mL) + Qualit (0.6 mL) (Bacillus subtilis+ Trichoderma asperellum) and T3) Control. After the production cycle, the total production (g kg-1), estimated average production (kg ha-1) and number of fruits in each plot were evaluated. 'Festival' and 'Oso Grande' were the most productive cultivars and their greatest yields were observed in the presence of Bacilluscompared to control. Plants grown in the presence of B. methylotrophicusand B. subtilisshowed a higher number of fruits. The use of these biological products is important for strawberry cultivation.

Numerous factors lead to the use of water with saline levels above those suitable for plant development, resulting in negative consequences on crops. Studies have sought techniques that aim to mitigate such consequences and the use of vitamins is promising, since these compounds improve the development conditions of vegetables. Thus, the study aimed to verify the ability of vitamins to mitigate the deleterious effects of using saline water, applied via irrigation during the formation of cucumber seedlings. Cucumber seeds were subjected to imbibition in three vitamin solutions (100 mg L-1thiamine; 100 mg L-1niacin; 50 mg L-1thiamine + 50 mg L-1niacin), in addition to two controls, both with water imbibition . After sowing, irrigation was carried out with saline water (100 mM NaCl), for all treatments, except for one of the controls. It was found that irrigation with saline water affected all variables studied, without, however, having a positive effect from the application of vitamins. Thus, it was concluded that the vitamins were not able to mitigate the deleterious effects caused by the application of saline water under the conditions in which the study was carried out and that future studies should be carried out to evaluate different concentrations and forms of application of the vitamins.

O objetivo deste trabalho foi investigar a percepção do sujeito que cometeu tentativa de suicídio diante da continuidade ou não do acompanhamento e tratamento. Estudo descritivo com abordagem qualitativa, desenvolvido com pacientes encaminhados e referenciados por um serviço de emergência para centros especializados (Centros de Atenção Psicossocial - CAPS) da Rede de Saúde, no Município de Santa Cruz do Sul, Estado do Rio Grande do Sul, Brasil. Foram entrevistados 11 sujeitos que tentaram suicídio, tendo como média a idade de 41 anos. A análise resultou na identificação e classificação de três categorias: a voz que dá significados à realidade do ato, o acompanhamento como escolha e compreensão e o não acompanhamento como decisão. Os sentimentos relatados pelos sujeitos exprimem sentidos, intensidades e dimensões da realização da tentativa de pôr fim à suas vidas. As dificuldades encontradas na continuidade dos tratamentos mostram a falta de qualificação e preparação dos profissionais em saúde, nos centros especializados, particularmente do serviço de emergência.

Este estudo teve como objetivo investigar a constituição identitária de uma professora, na narrativa de sua história de vida, considerando a imaginação no processo narrativo. Realizamos uma abordagem do self dialógico, por meio de entrevista narrativa e episódica, com uma professora de Biologia, do 6º ao 9º ano, de uma escola particular do Distrito Federal. Na pesquisa, utilizamos a análise temática dialógica da conversação com tabela e mapa semiótico. Reconhecemos que a identidade docente se constitui como processo dialógico do self com a participação da imaginação na elaboração da imagem que o indivíduo tem de si como herói de sua história. Os resultados sugerem uma diferença entre o posicionamento docente da professora e o seu contexto profissional, consequente da relação dialógica entre seus posicionamentos e o valor da afetividade na relação com os alunos.
