Authors: Ogundunmade Tayo P , Adepoju Adedayo A , Allam Abdelaziz
Published: June 2022

Background: Stock exchange price prediction is one of the most researched topics, attracting interest from both academics and industry. Various algorithms have been developed since the introduction of Artificial Intelligence (AI) and have been used to forecast equities market movement. Despite all these researches, less attention has been paid to the use of cross validation (CV) approaches for better stock price prediction. Objective: The aim of this work is to predict Nigerian stock prices using machine learning models with K-fold and repeated K-fold CVs. Methods: In this work, we consider the prediction performance of machine learning models under two cross validation approaches, namely K-fold and repeated K-fold CVs and when no cross validation technique is used. The models consider here are simple linear regression model, random forest (RF), classification and regression tree (CART), and artificial neural network and the support Vector Machine model. Standard strategic indicators such as root mean square error and mean absolute error are used to evaluate the models. The financial data including real gross domestic product, inflation rate, exchange rate and interest rate are used as the input units in the model. Results: Predicting models with CVs technique exhibit superior performance to models with no CV technique involved. Conclusion: Modelling and forecasting stock exchange prices using RF model with CV are conducive to prediction for stock exchange price in Nigeria. Future research are warranted to consider other machine learning models with CVs approaches.

Clinical Evaluation of Corneal Neovascularization: A Brief Review
Authors: Barut Selver Mukaddes Damla Ciftci and Ozlem
Published: June 2022

The healthy cornea is optically transparent tissue. Basically 3 features of the cornea provide its transparency: avascularity, constant water content and regular arrangement of collagen fibers. When the cornea loses its optically clear structure, it inevitably causes a decrease in visual acuity. Infection, inflammation, limbal stem cell deficiency, tumors and contact lens usage can cause corneal neovascularization. Disruption of the balance between angiogenic and antiangiogenic factors on the ocular surface plays a role in the pathogenesis of corneal vascularization. Most of the treatment options used in daily practice are effective when neovascular vessels are immature.
The Sailors’ Revolution
Authors: Arias Neto José Miguel
Published: June 2022

Este artigo discute o movimento dos marinheiros de 1910, procurando caracterizá-lo como um momento da Revolução Republicana no Brasil. Trata-se de compreender os significados e sentidos que se apresentam no documento de reivindicações apresentado pelos Marinheiros ao governo Hermes da Fonseca, reconstruindo a sua historicidade no contexto do início da República. De fato, é neste momento que termos como “cidadãos” e “republicanos” estão adquirindo um sentido contemporâneo, em suas implicações sociais e políticas, assim como a idéia de direitos. Dois aspectos caracterizam este movimento revolucionário: a) a constituição do grupo que se autodenomina cidadãos portadores de direitos e b) a própria idéia do direito de ter direitos que fundamenta o movimento.
Pensando a paz entre as guerras: o lugar do ensino de história nas relações exteriores
Authors: Leite Juçara Luzia
Published: June 2022

No início do século XX, principalmente após a 1ª Guerra Mundial, historiadores e educadores passaram a se perguntar sobre a influência que o ensino de História poderia ter nas afinidades e hostilidades entre povos e nações, para além da sua já considerada função cívica. Os chamados “abusos” da História –refletidos em seu ensino para a infância e para a juventude– passaram a ser debatidos na Europa (especialmente França, Alemanha e Espanha) e nos EUA, alcançando diversas organizações internacionais (leigas e religiosas), incluindo desde sindicatos de professores até a Liga das Nações. A revisão dos programas escolares e de livros didáticos esteve no centro dessa discussão. Na América do Sul, essa iniciativa coube aos governos do Brasil e da Argentina que, representados por seus ministros das Relações Exteriores, assinaram, em 1933, um “Convênio entre o Brasil e a República Argentina para a Revisão dos Textos de Ensino de História e Geographia”. Neste artigo, investigamos os interesses políticos e educacionais –inseridos no contexto internacional– que proporcionaram a assinatura do Convênio, e consideramos a atuação conjunta de governos, de políticos e de intelectuais-professores na intenção de prevenir a excitação “no ânimo desprevenido da juventude a adversão a qualquer povo americano”.
Teoria historiográfica e prática pedagógica: as correntes de pensamento que influenciaram o ensino de história no Brasil
Authors: Azevedo Crislane Barbosa , Stamatto Maria Inês Sucupira
Published: June 2022

Este artigo explicita características de diferentes correntes de pensamento pedagógico e historiográfico, relacionando-as ao ensino de História. Infere-se que o conhecimento sobre docência em História altera-se a partir do quadro teórico-metodológico adotado. Assim, proporcionar a compreensão de diversas concepções de Educação e de História permitiria a re-significação de objetivos de aprendizagem a serem alcançados pelos alunos e de práticas didático-pedagógicas em sala de aula. Diante de problemas no ensino de História, acredita-se que o professor ao dominar diferentes concepções pedagógicas e históricas pode melhor definir e decidir sobre o tipo de conhecimento que trabalhará em sala de aula atendendo às especificidades de seu público escolar.
O discurso histórico presente no livro didático: uma abordagem ideológica e historiográfica
Authors: Santos Natalia Aparecida Tiezzi Martins dos , Coutinho Dolores Pereira Ribeiro
Published: June 2022

Esta pesquisa teve como objetivo tratar o discurso histórico presente em livros didáticos de História demonstrando os conteúdos reais das mensagens ideológicas que são veiculadas pelos mesmos. Para tal intento pretendeu-se buscar meios de explicar como tais discursos,construídos ideologicamente, se materializam no meio social, por meio da linguagem e se relacionam à classe social do sujeito proferidor. A pesquisa foi elaborada a partir da análise do livro didático Nova História Crítica de Mario Schimidt e da leitura de teóricos com Bakhtin, Bloch, Hobsbawm e Chartier, entre outros. Em nossa reflexão, atentamos para o fato de que criticar a forma como são produzidos os livros didáticos, sua composição e distribuição, tem grande relevância, contudo, há que se pensar e criticar a posição dos professores que não refletem sua prática docente e que ao agirem dessa forma colaboram com a disseminação das mais torpes “visões sociais de mundo”, inclusive aquelas presentes nos livros didáticos, não só da disciplina de história ensinada nas escolas, mas, também,de outras.Nesse sentido,a escola estaria agindo como um aparelho ideológico do Estado, que por meio de vários elementos, dentre eles, o livro didático, assegura a submissão à ideologia dominante ou domínio de sua prática.
Educação e Democracia em Córdoba/Argentina. As “pegadas” da tradição reformista no discurso educacional provincial
Authors: Abratte Juan Pablo
Published: June 2022

Neste trabalho abordaremos nós centrais do discurso político-pedagógico de um núcleo intelectual que, no entre guerras, desdobrou em Córdoba um projeto educacional de relevância para a historiografia educacional argentina. É um movimento que encontrou suas raízes na Reforma Universitária e buscou estender a ideologia reformista ao sistema educacional como um todo. Com influências espíritas e escolanovistas, esse núcleo desenvolveu uma série de alternativas pedagógicas que incluíam propostas legislativas, a criação de instituições educacionais e culturais, produções acadêmicas e intelectuais, inscritas em um discurso profundamente crítico em relação ao modelo escolar hegemônico e seus vínculos com o projeto educacional .civilização do estado. Este movimento, cujos expoentes centrais são Saúl Taborda e Antonio Sobral, articulou diversos setores políticos, acadêmicos e sindicais em torno de suas propostas inovadoras. O propósito que norteia nossa investigação não é realizar uma análise exaustiva do pensamento desse núcleo reformista, mas sim traçar nele alguns "rastros" que serão recuperados pelo discurso educacional provincial da primeira administração pós-ditatorial no 'anos 80. Defendemos que a Reforma Educacional de Córdoba recuperou fragmentos dessa matriz alternativa, articulando passado, presente e futuro com o propósito de hegemonizar o campo político-educacional.
Projeção do Brasil para o pós-guerra: a ‘Boa Vizinhança’ estadunidense no Brasil segundo a revista ‘Em Guarda’ (1941-1945).
Authors: Locastre Aline Vanessa
Published: June 2022

A revista estadunidense "Em Guarda", veiculada em vários países americanos (inclusive no Brasil) durante a Segunda Guerra Mundial (1939-1945) traz em seus mais de 720 artigos, elementos que contribuem para uma análise de como os Estados Unidos tentaram impedir os países do "Eixo" de tornarem a América Latina sua zona de influência. Para tanto, os Estados Unidos mostraram-se os porta-vozes do progresso, da democracia e de admiráveis valores morais, que eram transmitidos por meio do rádio, do cinema, de revistas, de programas econômicos e de saúde. A imagem modelar da sociedade procurava ser disseminada por artistas, músicos e intelectuais e não por imposição militar. Nesse esforço em construir uma boa imagem da nação estadunidense, dentro da "Política da Boa Vizinhança", estava a publicação da revista "Em Guarda", que foi editada entre 1941 e 1945, e acompanhou a participação das Américas na guerra. Nosso foco de estudo propõe a análise do conteúdo impresso dos quatro anos de edição e assim entender um pouco mais sobre a Política da Boa Vizinhança e verificar as projeções de um Brasil no pósguerra, por meio do olhar dos editores do periódico.
A Canção como Mediação nos Livros Didáticos de História na Coleção História e Vida Integrada de Nelson e Claudino Piletti (1997-2007)
Authors: Xavier Érica da Silva
Published: June 2022

Neste trabalho buscamos compreender como os livros didáticos de história, mais precisamente os da coleção História e Vida Integrada propõem a canção dentro de seus conteúdos no período de 1997 a 2007. Objetivamos investigar se os livros didáticos desta coleção caracterizam a canção enquanto fonte histórica possibilitando a mediação entre as fontes e o conhecimento. Pois, entendemos que esta discussão é essencial uma vez que esta coleção sempre teve grande aceitação por parte dos professores durante o período investigado. Consideramos que o docente se vale de várias ferramentas mediadoras que o auxiliam nesse processo, entre elas a canção e o próprio livro didático, uma vez que não podemos limitar a ação do professor a ser apenas baseada no manual. Porém, o livro didático enquanto artefato mediador entre o professor e as fontes históricas não deve caracterizar estas de forma simplificada, transformando-as em uma mera ilustração de conteúdo ou reflexo da realidade. As fontes devem assumir um papel fundamental de significação na estrutura cognitiva do aluno: demonstrar as representações que determinados grupos forjaram sobre a sociedade em que viviam como pensavam ou sentiam, como se estabeleceram no tempo e no espaço; como servir para que o aluno seja capaz de fazer diferenciações, abstrações que o permitam fazer a leitura das distintas temporalidades as quais estamos submetidos. Com estas preocupações em mente é que fizemos esta investigação.
Narrativas de futuros professores de História sobre os afrobrasileiros no contexto do pósabolição: um estudo em meio a Lei Federal 10.639/03
Authors: Murinelli Gláucia Ruivo
Published: June 2022

O presente estudo teve como objetivo central refletir – em tempos da Lei Federal 10.639/03 que estabeleceu a obrigatoriedade do ensino de História e Cultura Afrobrasileira e Africana em todas as instituições de ensino no país – sobre os sentidos e princípios orientadores presentes em narrativas históricas de futuros professores do norte paranaense sobre a História dos afrobrasileiros no contexto do pós-abolição. Para tanto, foram estabelecidos diálogos, principalmente, com a atual produção historiográfica delineada no campo da História Social dedicada ao estudo dos egressos da escravidão em meio à conquista da liberdade, bem como com as contribuições de Jörn Rüsen (2001; 2001b) acerca do conceito de narrativa consubstanciadas à luz da Teoria da História. A atual produção historiográfica dedicada à população negra no período pós-emancipação foi enfatizada por dialogar com o objetivo da legislação, ou seja, trazer à tona a historicidade da população afrobrasileira. A narrativa histórica, por sua vez, foi entendida como o modo pela qual se manifesta as representações da humanidade no tempo e, além, a forma pela qual os homens interpretam de forma significativa o tempo a fim de se orientar intencionalmente no mundo. A amostragem envolveu 141 produções narrativas de graduandos do último período das licenciaturas em História da FAFIMAN, UEL, UEM e UENP. Coletadas a partir de instrumento de investigação, essas produções passaram pelo crivo da técnica de análise textual qualitativa e/ou análise de conteúdo desenvolvida por Laurence Bardin (1977). Os resultados da investigação apontaram, em suma, para a implementação das instruções da legislação nos espaços de ensino superior público do norte paranaense mediante a introdução de disciplinas específicas que versam sobre as africanidades. Assinalaram que 91% dos futuros professores aprovam a introdução do ensino e aprendizagem das africanidades nos espaços educacionais brasileiros. Também indicaram que os conteúdos históricos imersos nas narrativas históricas dos graduandos sobre os afrobrasileiros no contexto do pós-abolição se aproximam às contribuições de Florestan Fernandes (1972; 2008), fazendo com que o estudioso seja referenciado como o principal norteador desses futuros professores. O presente trabalho teve como intuito contribuir para a reflexão sobre a implementação e efetivação de políticas educacionais de ação afirmativa – representada pela Lei Federal 10.639/03 e seus desdobramentos – nas instituições de ensino perante a desconstrução e construção de sentidos sobre a História Afrobrasileira.

Repressão e violência de Estado contra os segmentos populares durante os governos militares
Authors: Rolim Rivail Carvalho
Published: June 2022

Inúmeras pesquisas analisaram variados aspectos acerca do exercício do poder durante o regime militar, destacando inclusive a repressão e a violência levada a cabo pelas forças repressivas contra os grupos políticos que se opuseram a esse regime. Contudo, depois de anos de pesquisas novos olhares começam a ser lançados sobre a ditadura no Brasil. Como havia uma concepção bastante ampla relativa às tensões e aos antagonismos existentes no país e quais os segmentos sociais que poderiam provocá-las, este trabalho tem como objetivo analisar a violência do Estado contra as classes populares, tendo em vista que foram consideradas como portadoras de um potencial desagregador e perigoso e despreparadas para viver em uma sociedade moderna, industrializada e de vida marcadamente urbana.

Introduction:

This multicenter cohort study investigated the association of serology and comorbid conditions with septic and aseptic nonunion.

Methods:

From January 1, 2011, to December 31, 2017, consecutive individuals surgically treated for nonunion were identified from seven centers. Nonunion-type, comorbid conditions and serology were assessed.

Results:

A total of 640 individuals were included. 57% were male with a mean age of 49 years. Nonunion sites included tibia (35.2%), femur (25.6%), humerus (20.3%), and other less frequent bones (18.9%). The type of nonunion included septic (17.7%) and aseptic (82.3%). Within aseptic, nonvascular (86.5%) and vascular (13.5%) nonunion were seen. Rates of smoking, alcohol abuse, and diabetes mellitus were higher in our nonunion cohort compared with population norms. Coronary artery disease and tobacco use were associated with septic nonunion (P < 0.05). Diphosphonates were associated with vascular nonunion (P < 0.05). Serologically, increased erythrocyte sedimentation rate, C-reactive protein, parathyroid hormone, red cell distribution width, mean platelet volume (MPV), and platelets and decreased absolute lymphocyte count, hemoglobin, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and albumin were associated with septic nonunion while lower calcium was associated with nonvascular nonunion (P < 0.05). The presence of four or more of increased erythrocyte sedimentation rate, C-reactive protein, or red cell distribution width; decreased albumin; and age younger than 65 years carried an 89% positive predictive value for infection. Hypovitaminosis D was seen less frequently than reported in the general population, whereas anemia was more common. However, aside from hematologic and inflammatory indices, no other serology was abnormal more than 25% of the time.

Discussion:

Abnormal serology and comorbid conditions, including smoking, alcohol abuse, and diabetes mellitus, are seen in nonunion; however, serologic abnormalities may be less common than previously thought. Septic nonunion is associated with inflammation, younger age, and malnourishment. Based on the observed frequency of abnormality, routine laboratory work is not recommended for nonunion assessment; however, specific focused serology may help determine the presence of septic nonunion.

History education being the queen or mother of all courses especially in art and social sciences is always ready to offer a helping hand in solving difficult riddles, paradoxes and problems bedeviling humanity such as insecurity, Covid 19 and other forms of social problems notwithstanding! This study has as much as possible intends to diagnosed the roles that History education can play in mitigating insecurity and COVID-19 challenges in Nigeria, the historical approaches and lessons adopted by past generations in solving life threatening challenges as well as the impacts of stimulus packages and relief materials on cushioning the effects of Covid 19 and insecurity. Survey research design where questionnaires were used in sampling opinions was adopted. Consequently, threat to food security, lost of lives, hunger and displacement of people are some of the discovered effects of insecurity. Meanwhile, unemployment, lack of good education, poverty etc were identified as some of the causes. However, strict adherence to government’s directives on constant hand washing, use of face mask, social distancing, provision of jobs, security of people’s lives and properties etc were recommended as possible solutions to the challenges of Covid 19 and insecurity
Evaluation of thyroid function and metabolic parameters in obese and overweight children: A prospective case-control study.

Published: June 2022

Obesity is considered an important global public health challenge, and its prevalence is rapidly increasing in children. We investigated in this study if the upper-normal TSH level may be associated with metabolic syndrome parameters, including obesity, high blood pressure, and dyslipidemia and changes in insulin sensitivity in overweight and obese children. We also investigated whether there is a relationship between BMI and these parameters. This prospective case-control study comprised 145 participants (74 females, 71 males) aged 5–18 years. Participants were divided into three groups according to their BMI z-score, as overweight, obese and control. The control group
included 35 age and sex-matched healthy subjects. Thyroid stimulating hormone levels of control, overweight and obese groups were 2.14 ± 1.27, 2.97 ± 1.26 and 3.13 ± 1.11, respectively (p<0.05). There was a significant positive correlation between TSH and the BMI, BMI z-scores between overweight and obese groups (r=0.302, p=0.000), (r=0.121, p=0.004), respectively. The current study suggests that increased serum TSH levels, even within the normal range, in overweight and obese children is associated with the impairment of metabolic parameters, including dyslipidemia and insulin sensitivity. For that reason, TSH levels in the high-normal range should be considered as a risk factor for metabolic syndrome and its components.
Changes in chloremia, secondary to hydric reanimation during the first 24 hours, increases hospital stay and complications in patients with acute pancreatitis.

Published: June 2022

Acute pancreatitis (AP) requires first-line treatment with intensive fluid resuscitation. Hydroelectrolyte changes secondary to this management could be related to an increase in hospital stay, complications, and mortality. The objective of this study was to correlate the increase in serum chlorine (> 8mEq / L) during the first 24 hours (ISC) with a longer hospital stay, complications and mortality in patients with AP. A total of 110 patients with AP admitted to the emergency room were included. Fluid management
and serum chlorine were recorded on admission and after 24 hours; duration of hospital stay, complications and mortality, were also registered. 37 patients had ISC (age 56.4 ± 18.4 years; 51% women), there were no differences in age, sex or type of fluid management with patients without ISC. In bivariate analysis, ISC was associated with severe AP (30% vs 12%, p = 0.02), higher APACHE II score at admission (8 [6-15] vs 6 [4-9] points, p = 0.006), and longer hospital stay (9 [7-12] vs 7 [5-10] days, p = 0.03). The overall mortality and complications rate were 16% and 25%, respectively, with no differences between the groups (24% vs. 12%, p = 0.1 and 35% vs. 19%, p = 0.06). After multivariate adjustment, independent predictors of hospital stay were ISC> 8 mEq / L (p
= 0.01) and APACHE II scores at 24 hours (p = 0.02). We conclude that ISC is associated with a longer hospital stay in patients with AP from a second-level hospital care population.

Authors: Ko Jenny J. , Adams Julia , McMillan Tara , Sunderland Katherine , Goulart Jennifer , Rauw Jennifer , Parimi Sunil
Published: June 2022

Introduction: Unresectable and metastatic small cell carcinoma of the prostate (SCPC) is a rare and aggressive disease that is under-represented in clinical trials. We carried out a retrospective chart review of metastatic or unresectable SCPC patients at British Columbia (BC) Cancer centers, studying diagnosis and treatment patterns.
Methods: Drug dispensing records from the six BC Cancer centers were obtained from 2002–2017. For each patient, information was collected on baseline information prior to therapy, and for each line of treatment. Treatments at each line were compared regarding time to progression and overall survival by Kaplan-Meier curves.
Results: Forty-one patients received treatment; 65.6% had metastatic disease and 61% had pure small cell carcinoma. Median time from treatment to death was 10 months (95% confidence interval [CI] 6–16). Patients with initially prostate-confined disease had a better median overall survival (mOS) of 21 months (95% CI 13–34) compared to those with initially locally advanced (mOS 19 months, 95% CI 5–37) and metastatic disease (mOS 8 months, 95% CI 6–10) (log-rank p=0.0364). All patients received either cisplatin- or carboplatin-based combination chemotherapy as the first-line treatment and 36.7% received second-line therapy. Time to second-line therapy was eight months for those who presented with metastatic SCPC, compared to 13 months for those with initial non-metastatic SCPC.
Conclusions: This single-province, multi-institution cohort reports data on unresectable and metastatic SCPC and highlights the poor prognosis of this rare disease entity.
Bipolar radiofrequency thermotherapy vs. transurethral resection of the prostate: Effect on nocturia as a result of benign prostatic obstruction
Authors: Yuce Ahmet , Benli Erdal , Cirakoglu Abdullah , Yazici Ibrahim , Nalbant Ismail
Published: June 2022

Introduction: The purpose of this study was to investigate and compare the effects of radiofrequency thermotherapy (RF) thermotherapy and transurethral resection of the prostate (TURP) on nocturia and associated quality of life in patients diagnosed with benign prostatic obstruction (BPO) under medical treatment who have complaints of persistent nocturia.
Methods: The results of patients who underwent RF thermotherapy and TURP procedures between February 2019 and February 2022 were examined, and their three-month results were compared based on their uroflowmetry values, International Prostate Symptom Score (IPSS) values, nocturia frequency, and Nocturia Quality of Life Questionnaire scores.
Results: While the frequency of nocturia in the RF thermotherapy group that was 4.5±1.6 before the procedure decreased to 2.3±1.4 after the procedure (p=0.002), this value in the TURP group decreased from 5.1±2.42 to 3.9±2.1 (p=0.044). RF thermotherapy was found to be more effective than TURP (p<0.005). Significantly more noticeable improvements were observed in most nocturia-related next-day complaints and nocturia-related concerns in the RF thermotherapy group than the TURP group.
Conclusions: It was observed that RF thermotherapy had a more acceptable effect on obstructive complaints in comparison to TURP, and it could be more effective on nocturia and associated quality of life. RF ablation treatment may be offered as an appropriate option to treat nocturia complaints in suitable patients.

Shape Control of Composite Structure with Suitably Placed Piezoelectric Sensors Under Electro-Thermo-Mechanical Condition with Non-linear Analysis
Authors: Rathnam P Mani
Published: June 2022

In this paper, the application of piezoelectric actuators to the composite control card is studied statically. The electro-thermo-mechanically coupled mathematical model is used for the analysis. The main section of this paper is static control. Shape control is stated here as determining the shape control parameters, including the actuation voltage and the adjustment of the actuator orientation, so that the structure which is activated using these parameters also adapts as closely as possible to the required shape. In this paper, we have presented FE model for the control analysis of the shape of piezoelectric laminated (PZT) composite plates using Ansys. The piezoelectric layer and composite plate are modeled in the form of additional layers to be attached to the upper or lower surface or to be integrated into the laminated composite plate. Ansys finite element software is used for modeling and has been successfully validated with experimental and numerical results which are readily available in the literature. The present analysis shows that with the application of an appropriate voltage to the piezoelectric actuator, the desired shape of the composite plate can be obtained. Keywords: Composite plate, FEM, Intelligent structure, Non- linear, piezoelectric, sensor, voltage

BIOACTIVE SECONDARY METABOLITES PRODUCTION BY TERRESTRIAL BACILLUS CIRCULANS STRAINS
Authors: Massadeh Muhannad I. , Al Masri Mona
Published: June 2022

Screening for antagonistic microorganisms is a promising tool for discovering new antimicrobial metabolites. In this study, two Bacillus sp. (HU6 and HU8) were isolated from soil and assessed for their antimicrobial activity by the agar-well diffusion method against different human pathogens. According to general characteristics, morphology, and physio-chemical properties of the isolates they were identified as Bacillus circulans. Both strains exhibited a broad spectrum of activity against Gram positive and Gram negative pathogenic bacteria. The highest antimicrobial activity was achieved from ethyl acetate extract of B. circulans HU6 against E. coli where the inhibition zone was 26.3 ± 0.82 mm. The bioactivity of the isolates extract was not affected when subjected to heat treatment or proteolytic digestion suggesting that the nature of the active metabolites was not proteinaceous. The  GC/MS analysis of the extracts revealed the presence of 4 bioactive compounds: Pyrrolo[1,2-a]pyrazine-1,4-dione, Trans-13-octadecenoic acid, 2,5-piperazine dione,3,6-bis (2-methyl propyl), and cis-13-eicosenoic acid.

Felső-Tisza ártéri legelőinek ásványianyag-tartalma
Authors: Győri Zoltán , Alapi Krisztina
Published: June 2022

Az állatok zavarlalan életműködéséhez a táplálékuknak megfelelő mennyiségben és arányban kell ásványi anyagokal tartalmaznia. A gyepek növényzelének elemtartalmát igen sok tényező befolyásolja. Többek között a hő, a csapadék, az öntözés, a talaj típusa és tápanyag-ellátottsága, a gyeptípusok, a fajösszetétel. a tenyészidőszak aspektusai, a növények fenofázisa, a gyephasználat módja.     A folyók árterében gyakran találunk extenzív hasznosítású legelőket, illetve természetes, nem telepített kaszálókat. Mivel ezen területeken kemikáliákat nem lehet alkalmazni, és a fajgazdagság nagy,  igen alkalmasak arra, hogy a különböző növények elemtartalmát meghatározzuk. 2001-es évben négy ártéri legelőről, illetve kaszálóról készítettünk cönológiai felvételezést és mértük meg az ott található növényfajok elemtartalmát.     Azok a növények, amelyeket nem vonnak be szándékosan a termelésbe, vagyis tágabb értelemben használva gyomnövények, igen értékes elemei a legelők növényzetének, mert az állatok számára értékes mikroelemekben gazdagabbá teszik a legelőt.     Az általunk vizsgált területeken, az ideálisnak tartott 2/3 rész egyszíkű, 1/3 rész kétszikű aránytól eltérő arányokat kaptunk, de ez nem eredményezett Mn-hiányt.
Műtrágyázás hatása a telepített gyep takarmányértékére és tápanyaghozamára 2.
Authors: Kádár Imre , Győri Zoltán
Published: June 2022

Egy műtrágyázási tartamkísérlet 28. évében, 2001-ben vizsgáltuk az eltérő N, P, K ellátottsági szintek és kombinációik hatását a réti csenkesz (Festuca pratensis) vezérnövényű, nyolckomponensű, pillangós nélküli gyepkeverék takarmányértékére. A termőhely talaja a szántott rétegben mintegy 3% humuszt, 3-5% CaCO3-ot és 20-22% agyagot tartalmazott, N és K elemekben közepesen, P és Zn elemekben gyengén ellátottnak minősült. A kísérlet 4N x 4P x 4K = 64 kezelést x 2 ismétlést = 128 parcellát foglalt magában. A talajvíz 13-15 m mélyen helyezkedik el, a terület aszályérzékeny. A vizsgált 2001. évben kielégítő, 621 mm csapadék hullott és annak eloszlása is kedvező volt. A kísérlet módszerét, valamint a műtrágyázás termésre és N-felvételre gyakorolt hatását előző közleményünk foglalta össze (Kádár, 2004).Főbb eredményeink:     1. Míg az 1. kaszálást adó anyaszéna hozamát az NxP pozitív kölcsönhatások határozták meg, a takarmányérték jellemzőit tekintve az NxK kölcsönhatások voltak a mérvadók. Az Nmka 532-ről 390 g/kg-ra csökkent az NK túlsúlya nyomán, ugyanitt a nyersfehérje tartalma 64-ről 183 g/kg értékre emelkedett. Az Nmka/nyersfehérje aránya a kontroll talajon mért 8,3-ról 2,1-re szűkült. A nyershamu tartalma 26%-kal, a MFN 286%-kal nőtt meg a kontrollhoz képest az NK-trágyázással.     2. A gazdaságilag optimálisnak tekinthető takarmányérték hozamokat már a 100 kg/ha/év N-adag biztosította a 150 mg/kg AL-P2O5 „közepes” ellátottság mellett a nyersrost, rostfrakciók (NDF, ADF), Nmka, nyershamu, NE1, NEm, NEg mutatók esetében az 1. kaszálásnál. A nyerszsír és az MFE hozamok optimumai a 200 kg/ha/év N-adag és a 333 mg/kg AL-P2O5 ellátottsághoz kötődtek. A nyersfehérje és a N-függő Metabolizálható Fehérje (MFN) optimumait ugyanakkor a maximális NP-kínálat biztosította, a kontrollhoz képest a hozamok megötszöröződtek.     3. A 2. kaszálású sarjúszéna termését és takarmányértékét a N-trágyázás növelte, a P és K hatásai elmaradtak. Maximális szénatermést és takarmányhozamokat általában a 300 kg/ha/év N-adag biztosította. Az 1+2 kaszálás összegeit tekintve általában 200 kg/ha/év N-adag bizonyult optimálisnak. Extrémebb különbségek léptek fel az egyes kezeléskombinációk között. Az abszolút kontroll (N0P0K0) kicsi hozamokat adott. Ehhez képest az egyoldalú mérsékelt N-trágyázás (N1P0K0) 2-3-szoros többleteket, míg a kiegyensúlyozott mérsékelt (N1P1K1) kezelés további ugrásszerű növekedést jelentett a takarmányérték hozamaiban. A N-függő nyersfehérje, ill. fehérjefrakciók (MFE, MFN), valamint a nyerszsír esetében a maximális hozamok a maximális (N3P3K3) műtrágya-kínálathoz kötődtek.     4. Összefoglalóan elmondható, hogy a bőséges vagy kielégítő trágyázással hasonló kedvező évben és tápanyagszegény talajon a nyersrost és a rostfrakciók (NDF, ADF), valamint a Nmka, nyershamu, nyerszsír és a nettóenergia mutatói (NE) 3-5-szörösére, a N-függő nyersfehérje és fehérjefrakciók (MFE, MFN) hozamai akár 7-8-szorosára növelhetők.

Azokról a farkaslaki pásztoremberekről akarok írni, akik a Gordon hegy alatti dombokon állottak napsütésben, csillagfényben, gyönyörködtek a kiviruló tavaszi határban, vagy a levélhullató őszben, de szemüket rajta tartották a legelésző juhokon, heverő kutyákon. Ott állottak az esőben, szélben, viharban is , éjjel keresték az elkódorgott juhot, ha kellett megküzdöttek a farkassal s néha a medvével is. Fejték a juhokat akkor is, ha azok lucskosak voltak, sároztatták a két lábukra feszülő fehérharisnyát, pásztortűz mellett szárítkoztak és csúcsosra húzott süveggel állották a záporokat. A közülük kiemelkedő tanult emberek éppen így állottak a dombokon, szemüket rajta tartva kis népükön.
vadaskert vadföldgazdálkodás ökonómiai kérdései
Authors: Nagy János
Published: June 2022

Az elmúlt két évtizedben jelentős változások zajlottak le a magyar vadgazdálkodásban. Nyereségorientált tevékenységgé vált, és ezzel meghatározóvá vált a gazdálkodás. Különösen igaz ez a vadaskertekre, ahol az intenzívebb hasznosítás feltétele a magas színvonalú takarmányozás. A vadászterületek jelentős gyepterülettel rendelkeznek, azonban ezek általában elhanyagolt, műveletlen földek. A Bőszénfai vadaskert vadföldművelését elemezve egyértelmű az eredmény, mely szerint az egynyári növénykultúrákkal szemben sokkal gazdaságosabb az évelő – elsősorban pillangós – vezérnövényű gyeptársulások létesítése. Ezzel évente akár 15-20% költségmegtakarítást érhetünk el, mindemellett gazdálkodásunk egyszerűbbé, áttekinthetőbbé válik.
