Published: April 2022

Currently in Nigeria, none of the products of micro insurance industry can be acquired by interested customers just the same way customers can acquire banking products at the comfort of their homes through the aid of technological advancement, this study hereby focused on enhancing the performance of micro insurance industry in Nigeria through online Insurance Products. Survey research design was employed for this study. Ordinary Least Square and Logit Binary Regression Models were employed to test the hypotheses of the study. To conclude this study, we should simply agree that Online Insurance Products and development of insurance industry are interwoven, and the ability of the insurance industry in Nigeria to use it as a stepping stone to move forward globally will not only promote their growth and development, but also contribute to the growth and development of the Nigerian economy. However, there are numerous challenges that insurance companies faced especially in the phase of online Insurance Products, these challenges are: integration processes, which encompass globalisation, consolidation and convergence, ever more frequent and intensified catastrophic events and the emergence of new risks, mainly caused by the emerging technologies. Arisen from this study, this study recommended that management of insurance business and the Nigeria government in particular should understand the humongous benefits that can accrual from Online Insurance Products. In the same light, Nigeria government should develop policies that can enhance the business operation of microinsurance industry to meet up with the challenges facing insurance industry in the phase of Online Insurance Products.

Challenges in oral health-related quality of life assessment
Authors: Milosevic-Markovic Maja , Jovanovic Svetlana
Published: April 2022

Oral health is an important part of general health, and the overall quality
of life directly depends on preserving the function of the orofacial system.
The use of exclusively clinical parameters does not adequately present
functional and psychosocial aspects of oral health and individual?s needs.
Therefore, the concept of oral health-related quality of life (OHRQOL) is
introduced to assess the impact of oral diseases on overall well-being.
Numerous questionnaires and scales adapted to the needs of different
population groups are used for this purpose. The OHRQOL measurement
facilitates the screening of hidden oral health problems in population and
directs the design of public health programs following the population?s
health needs. Although the use of OHRQOL assessment tools has improved
significantly in the recent years, it is still underrepresented in clinical
practice. There is a need to increase the use of the OHRQOL assessment
questionnaire in clinical practice in order to improve communication between
dentists and patients, facilitate the evaluation of final therapeutic
outcomes and improve the quality of dental health care.
Cenarab como uma experiência do movimento negro educador na educação de jovens e adultos
Authors: Oliveira Heli Sabino de , Santos Erisvaldo Pereira dos
Published: April 2022

Este trabalho examina a Educação de Jovens e Adultos (EJA) no Centro de Africanidade e Resistência Afro-Brasileira (Cenarab), focalizando arranjos espaciais, o lugar simbólico da professora e o material didático usado em sala de aula. Conquanto não seja propriamente um local religioso, o Cenarab é marcado por símbolos de cultos de matrizes africanas que interferem na experiência educativa da EJA. Fruto de uma pesquisa qualitativa, o trabalho coloca em relevo os conceitos de política de identidade, reconhecimento e currículo silencioso. Tomando como referência a obra Movimento Negro Educador de Nilma Gomes (2017), recorremos aos estudos de Gonçalves, McLaren e Frago. Por meio de entrevistas semiestruturadas e observação participante, constatamos que a proposta da EJA pode contribuir para construção de uma sociedade em que o diferente não seja tratado com desprezo, nem como ameaça.
Práticas educativas interculturais
Authors: Menezes Graziela Ninck Dias , Rios Jane Adriana Vasconcelos Pacheco
Published: April 2022

O artigo resulta de uma pesquisa que cartografou a profissão docente na Educação Profissional Técnica a partir de experiências educativas com a diversidade. Reflete como o processo civilizatório construído pela Razão Indolente (SANTOS, 2011) incide sobre a educação e destaca como a produção de práticas educativas interculturais (TUBINO, 2016; FLEURI, 2017) gera fissuras no processo formativo dos docentes e os reposicionam na profissão (NÓVOA, 2017). O trabalho se desenvolveu a partir da aplicação de um questionário survey, rodas de conversa e cartas pedagógicas com docentes do Instituto Federal da Bahia. Os resultados apontam que, diante o contexto da diversidade como campo de disputa e insurgência dos sujeitos, as fissuras produzidas nos processos formativos anunciaram-se como reconhecimento da formação específica que amparem as dimensões metodológicas, curriculares e políticas que cercam o campo pedagógico.

Published: April 2022

No Brasil, para a implementação da Lei nº 10.639/2003 é fundamental a descolonização dos currículos. Tal processo pode ser enriquecido a partir da conexão com os debates em países africanos acerca da crítica ao eurocentrismo. No artigo, apresentamos resultados de pesquisa de pós-doutorado e discutimos: a) sobre a crítica a preponderância do eurocentrismo; b) se as Histórias e Culturas construídas pelos/as próprios/as africanos/as integram os seus currículos e c) os desafios das políticas curriculares na África do Sul e em Moçambique para a incorporação de Indigenous Knowledge Systems (IKS). Por meio de pesquisa bibliográfica, utilizamos autores/as como Dei, Gomes, Mapara, Nhalevilo e Shizha. Concluímos que há dificuldades para que tais conhecimentos integrem os currículos devido à permanência da percepção de deslegitimidade desses em relação aos conhecimentos de base eurocêntrica.

Aim. To perform a screening for molecular markers of cardiac fibrosis upon myocardial infarction.

Materials and Methods. We carried out echocardiography-guided endomyocardial biopsy of affected and intact interventricular septum segments of 7 patients with anterior myocardial infarction. Fibrotic and adjacent intact cardiac tissue was dissected into 2 equal segments and: 1) homogenized with the further RNA extraction, reverse transcription, and quantitative polymerase chain reaction; 2) fixed in formalin and embedded into paraffin with the further van Gieson staining for the histological verification of cardiac fibrosis.

Results. We found that the expression of ACTA2, VIM, CTGF, COL1A1, TGFB1, TGFBR1, AGTR1, CCL2 and TNF genes in fibrotic cardiac tissue was ≥ 3-fold higher as compared with the adjacent intact myocardium reflective of active extracellular matrix production by fibroblast-derived myofibroblasts.

Conclusion. We have for the first time shown AGTR1, CCL2, and TNF genes as candidates for post-infarction cardiac fibrosis in addition to ACTA2, VIM, CTGF, COL1A1, TGFB1, and TGFBR1 genes.

Published: April 2022

Aim. To assess the impact of homeostasis parameters on risk of prostate cancer.

Materials and Methods. The study included 108  patients with urologic diseases and with (n = 54) or without (n = 54) prostate cancer. Median age in both groups was 67 (interquartile range 64-73) years. Clinicopathological data and blood test results have been collected from outpatient and inpatient records. In particular, we measured serum levels of total testosterone and prostate-specific antigen.

Results. Risk factors for prostate cancer include increased total cholesterol (p = 0.023), low-density lipoprotein cholesterol (p = 0.035), total triglycerides (p = 0.048), and total testosterone (p = 0.002). High levels of total testosterone directly correlated with the tumor stage (r = 0.56). The concentration of prostate-specific antigen correlated with the lipid parameters and remained a reliable diagnostic criterion (p = 0.002).

Conclusion. The association of hyper/dyslipidemia with prostate cancer provides an opportunity to improve its prevention by routine lipid screening in high-risk groups.

Published: April 2022

Aim. To evaluate the activity of the 4-1BB/4-1BBL signaling pathway in patients with influenza A (H1N1) virus-associated pneumonia.

Materials and Methods. Here we enrolled 85 patients (41 males and 44 females, median age 48 (36-62) years) with influenza A (H1N1) virus-associated pneumonia. Among the exclusion criteria were unstable hemodynamics, BMI > 30, diabetes mellitus, HIV, tuberculosis, and cancer. Control group consisted of 15 healthy donors. The diagnosis of influenza A / H1N1 was confirmed by a positive PCR test. Pneumonia was diagnosed according to the Federal Clinical Guidelines «Community-acquired pneumonia in adults». Severity of pneumonia was evaluated by using CURB-65 and SMART-COP scales as well as IDSA/ATS criteria. Plasma concentration of 4-1BB (CD137 or TNFRSF9, an inducible costimulatory receptor expressed on activated T cells and antigen-presenting cells) was determined by flow cytometry.

Results. Patients with moderate and severe influenza A (H1N1) virus-associated pneumonia had 1.5- and 2.4 fold-increased concentration of plasma 4-1ВВ as compared with the healthy controls.

Conclusion. The 4-1BB/4-1BBL signaling pathway, involved in multiple immune reactions, is associated with the severity of influenza A (H1N1) virus-associated pneumonia.

Authors: Artymuk N. V. , Parfenova Y. A. , Tachkova O. A.
Published: April 2022

Aim. To evaluate the trends of vaccination against COVID-19 among pregnant women in Siberia for the period from October 29, 2021 to November 26, 2021.

Materials and Methods. The vaccination data have been collected from official records from October 29, 2021 (86,859 pregnant women) and November 26, 2021 (85,600 pregnant women) in 10 regions of Siberia.

Results. Before the pregnancy onset, as of October 29, 2021, only 4,056 (4.7%) women had past medical history of COVID-19. These numbers have significantly increased to November 26, 2021 (5,656, 6.6%, p < 0.001). The number of vaccinated pregnant women increased from 4,185 (4.8%) to 8,318 (9.7%) (p < 0.001). As of November 26, 2021, we registered a reduced proportion of women vaccinated at the preconception stage (from 4.6% to 4.0%, p < 0.001), yet the number of vaccinated pregnant women raised both before (from 0.7% to 1.3 %, p < 0.001) and after 22 weeks of pregnancy (from 1.6% to 2.3%, p < 0.001). The highest proportion of pregnant women was documented in the Tyva Republic and the Irkutsk Region (p < 0.01). Major vaccination-associated adverse events have not been reported.

Conclusions. The proportion of pregnant women recovered or vaccinated from COVID-19 increased from October 29, 2021 (16.4%) to November 26, 2021 (23.9%); however, this rate is clearly insufficient to reach herd immunity and reduce maternal mortality from COVID-19.

The handling of covid-19 in the world, and in Burundi in particular, requires early and appropriate proactive measures in response to the rate of spread. In this paper, we analyze two key factors: the confidence of the government in the management of covid-19 and the degree of compliance with the measures undertaken by the government to handle it. A statistical classification of the variables considered with principal component analysis is also analyzed in order to identify similarities and differences in the behavior of the Burundian population with respect to the covid-19 pandemic.
Parental Involvement Strategies and Challenges in Development of Pupils’ Literacy Skills in the Implementation of Competency Based Curriculum in Early Years Education in Kenya
Authors: Syomwene Anne
Published: April 2022

Parents are the first teachers of a child and can greatly influence a child’s performance in school. This paper is a report of a study that was carried out in the year 2021on parental involvement strategies and challenges in the development of pupils’ literacy skills in the implementation of Competency Based Curriculum (CBC) in Early Years Education (EYE) in Kenya. The study adopted a qualitative research methodology and a descriptive research design. This study was anchored on Epstein’s theory on parental involvement in education. The target population consisted of teachers and parents in Early Years Education level in private and public schools in Kapseret Sub-County, Uasin-Gishu County in Kenya. Stratified and simple random sampling methods were used to select six private schools and six public schools to participate in the study. One parent in every school was selected through convenience sampling method. A total of twelve teachers and six parents participated in the study. Data was collected using interviews. The study found out that teachers were involving parents in the development of pupils’ literacy skills through reading and writing activities, home-work exercises, acquisition of reading and writing materials, and use of story-telling and singing pre-reading activities. From the findings, the most serious challenges experienced were lack of cooperation and limitations of time by some parents; limitations of reading and writing materials especially in the public schools; and limited knowledge and skills by teachers and parents on CBC philosophy and principles. The public schools were more challenged on parental engagement compared to the private schools. The study recommended that the government should escalate capacity building seminars for teachers; schools should organize parental awareness seminars; the government should provide adequate reading and writing materials in public schools; and parents be sensitized to create more time for their children’s education. This study is significant as it informs the implementation of the CBC for Kenya and elsewhere and enhancement of parent-teacher relationships in children’s literacy development.
Capacity of Self-Sealing Concrete Embedding Crystalline Admixture
Authors: Ndoj Genciana , Kastrati Armona , Elezi Erisa , Xhexhi Klodjan
Published: April 2022

Concrete is one of the most intelligent and widely utilized man-made materials in the construction industry. Despite this, even high-quality concrete is susceptible to porosity, which reduces its serviceability period. Furthermore, there is an increasing need to increase longevity due to environmental exposure such as soil moisture, corrosive outside elements, or structural defects forming in the surface of concrete. The use of crystalline admixtures in concrete is one of the many approaches to reducing these risks. When crystalline admixtures come into contact with water, they form thin crystals that fill pores, capillaries, and micro fractures, as a result making concrete a self-sealing material. When the concrete has dried, the crystalline particles remain dormant until they come into contact with additional water, which causes them to crystallize once more.
This research aims to analyze and compare the material properties between commonly used concrete and concrete where crystalline waterproofing is present.  Furthermore, experiments are conducted to evaluate each of the concrete samples: compressive strength, water permeability and flexure strength. As a result, demonstrating benefits or negative aspects in the use of crystalline admixture in the early stages of concrete is important. It is not yet defined, weather this is the future of cutting-edge concrete and the impact that it will have in the Albanian building market.

Authors: García-Pérez César A. , Menchaca-Campos Carmina , García-Sánchez Miguel A. , Uruchurtu Jorge
Published: April 2022

Composite materials were manufactured to obtain singular properties to be used as in electrochemical driven energy systems. An electrochemical evaluation was performed on electro-spun nylon 6,6 fibers (Ny), with different concentrations of tetra-para-amino-phenyl porphyrin (PP) and graphene oxide (GO) composite coating over stainless steel (SS), immersed in 1M H2SO4 aggressive sulfuric acid solution. Different film coatings behavior was obtained and compared using electrochemical impedance spectroscopy (EIS). Also, cyclic voltametry (CV) were performed on nylon/PP/GO composite coating system at different scan rates, and over film covered carbon cloth. For the electro-spun composite coating on stainless steel EIS, lower electro-spinning times present higher impedance, hence some corrosion protection. For greater electro-spinning times, larger capacitance values were observed. These were possibly due to thicker coating or mass transport adsorption-diffusion process through the composite film, respectively. For the composite coating, porphyrins, and graphene oxide interaction present ionic conductivity, reducing the impedance and promoting proton formation, property which could be used in charge storage systems.
Assessment of Preferable Breeding Method Use and Related Limitations under Smallholder Dairy Farmers’ Conditions: A Case Study in Selected Districts Southern Highland Zone of Tanzania
Authors: Mwaipopo Lokoo Chubby , Mbaga Said H.
Published: April 2022

A study was carried out to assess status and preference of smallholder dairy farmers on breeding method use under smallholder dairy cattle production in Southern Highland zone of Tanzania. Three districts namely Njombe, Mbeya and Mbozi were purposively selected for data collection. Data were collected using a questionnaire. A total of 180 dairy farmers in three districts were voluntary interviewed. Results showed that many of dairy farmers’ age range between 41 to 50 years (33%) of respondents, 48% of respondents (48.9%) had primary education, many farmers were found not to be working in groups (82.2%) and majority had never received any training on dairy husbandry (81.1%).

Zero grazing was the main management system (97.2%) used by farmers in all districts. Cows’ sheds were partially roofed, and the floors were soiled (48.9%). Mean dairy herd size was 5.21 per household and natural service was the predominant breeding method (55%) under smallholder farms production system. Farmers’ main reason for using AI was to improve genetic potential of their animal (48.8%). Under this system the major challenges of AI service were inefficient semen supply and poor heat detection. Natural services are widely used since it is easily accessible and cheaper. It therefore concluded that use of natural service is still a predominant method of choice in breeding due to unreliability and inefficiency associated with AI service in the Southern Highland zone of Tanzania.

Published: April 2022

Esta investigación se motiva en los emergentes de un trabajo doctoral en curso que explora el acceso al derecho a la ciudad desde el punto de vista de las mujeres en un barrio periurbano de la ciudad de Mar del Plata. El avance de la pesquisa se tropezó con relatos que problematizaban el acceso a la salud sexual y (no) reproductiva por parte de las entrevistadas lo que, sumado a la conquista histórica del derecho al aborto en el año 2020, llevó a dos interrogantes: ¿cuáles son las condiciones en las que actualmente las mujeres del barrio Nuevo Golf de la ciudad de Mar del Plata acceden a la atención primaria de la salud sexual y (no) reproductiva? ¿Qué experiencias fueron ya discutidas y qué estrategias fueron consensuadas sobre esta temática al seno del Encuentro Nacional de Mujeres en tanto espacio político? Mediante el análisis de discurso y documentos, este artículo busca generar un aporte para el efectivo acceso a la interrupción voluntaria del embarazo desde una mirada territorializada del derecho a la salud y la ciudadanía sexual.
Procesos de apropiación subjetiva del derecho a la Interrupción legal y voluntaria de embarazo (ILE/IVE) de mujeres que transitaron la práctica en Chubut
Authors: Espinoza Casanova Julieta
Published: April 2022

Este artículo presenta los avances de una investigación que busca conocer los procesos de apropiación subjetiva del derecho a la interrupción legal y voluntaria del embarazo de mujeres que transitaron la práctica en el sistema de salud pública en la ciudad de Rawson, Chubut, en el marco de la ley provincial XV n 14 (ILE) y la nacional 27.610 (IVE).

Este estudio es de tipo cualitativo, exploratorio y descriptivo; de diseño flexible e inductivo, y utiliza como herramienta de construcción de datos entrevistas semi-estructuradas. El proceso reflexivo se inscribe en epistemologías feministas y se piensa desde una perspectiva psicosocial. Lo trabajado hasta el momento, permite pensar a la apropiación subjetiva del derecho a la ILE/IVE como un proceso constituidos por múltiples aristas. En el mismo se entraman tensiones entre la legalidad de esta práctica y lo socialmente legitimado de ella; hecho que se hace visible a través de los propios posicionamientos de las mujeres como sujetas que se reconocen titulares de este derecho; de las polifonías de voces presentes en esas construcciones y en los sentires sobre su experiencia, adquiriendo significatividad la dimensión de género. El propósito de la investigación es aportar elementos para conocer los modos en que la interrupción legal y voluntaria del embarazo adquiere realidad en el plano de las subjetividades, aportando insumos no sólo a la implementación de la política pública, sino también a la construcción de posiciones éticas ciudadanas desde las cuales ser sujetas con y de derecho.

Badania prowadzono w doświadczalnym sadzie jabłoniowym na glebie płowej typowej wytworzonej z utworu pyłowego. Porównano następujące metody pielęgnacji gleby w rzędach drzew: ugór herbicydowy utrzymywany za pomocą simaziny (Azotopu), ugór herbicydowy utrzymywany za pomocą glifosatu (Roundupu 360SL) i ugór mechaniczny utrzymywany ręcznym gracowaniem. Wyniki badań wykazały, że ugory herbicydowe utrzymywane za pomocą Azotopu i Roundupu nie spowodowały pogorszenia właściwości wodnych w poziomach Ap i Bt gleby płowej wytworzonej z utworu pyłowego. Polowa pojemność wodna i retencja wody użytecznej dla roślin w glebie pod ugorami herbicydowymi były bardzo korzystne, zbliżone do właściwości gleby pod ugorem mechanicznym, lub nawet większe. Także przewodnictwo wodne nasycone gleby pod ugorami herbicydowymi było zbliżone do przewodnictwa wodnego gleby pod ugorem mechanicznym.
Charakterystyka pokrywy śnieżnej w Obserwatorium Agrometeorologicznym w Felinie (1955/1956–2004/2005)
Authors: Bartoszek Krzysztof
Published: April 2022

Liczba dni z pokrywą śnieżną w Felinie charakteryzuje się dużą zmiennością z roku na rok. Uwagę zwracają śnieżne zimy lat 60. i mało śnieżne z pierwszej połowy lat 70. oraz końca lat 80 XX w. Średnia liczba dni z pokrywą śnieżną w Felinie wynosi 68, największe prawdopodobieństwo jej zalegania (78%) przypada na przełom stycznia i lutego, a największą grubość obserwuje się zwykle pod koniec lutego. Przeciętnie pierwszy dzień z pokrywą śnieżną pojawia się wraz z końcem listopada, a ostatni w trzeciej dekadzie marca. Rzadkością w analizowanym wieloleciu były przypadki, gdy pokrywa zalegała bez przerwy dłużej aniżeli 70 dni. Na podstawie typologii cyrkulacji Hessa-Brezowsky’ego stwierdzono, iż w najbardziej śnieżnych zimach w Felinie długie zaleganie pokrywy śnieżnej było skutkiem zwiększonej częstości występowania południkowych form cyrkulacji oraz układów wysokiego ciśnienia nad Europą Środkowo-Wschodnią. Z kolei w najmniej śnieżnych zimach dominowały strefowe formy cyrkulacji, czego odzwierciedleniem była większa częstość wędrujących niżów nad Morzem Bałtyckim.
Ocena zmian zawartości mikroelementów w zbożach pod wpływem wapnowania i magnezowania gleby
Authors: Błaziak Jadwiga
Published: April 2022

Badania oparto na doświadczeniu wazonowym w hali wegetacyjnej. Materiałem glebowym był utwór pyłowy wodnego pochodzenia, o odczynie bardzo kwaśnym. Czynnikami doświadczenia były: kontrola (bez nawożenia) oraz CaO, CaO + MgO i MgSO4. 7H2O, zastosowane według 1 kwasowości hydrolitycznej. Roślinami testowymi były jęczmień jary i owies. Zboża zebrane z obiektu kontrolnego wykazywały wysoką zawartość żelaza, manganu i cynku. Wapnowanie i magnezowanie spowodowało znaczne obniżenie zawartości mikroelementów w roślinach, a szczególnie Mn o 25–90% oraz Zn o 15–60% i Fe o 15–40%. Wpływ CaO i CaO + MgO na obniżenie zawartości mikroelementów w zbożach był podobny. W przypadku owsa nastąpił spadek do zawartości niskich. Siarczan magnezu miał znacznie mniejszy wpływ.
Pszeniec różowy (Melampyrum arvense L.) jako element krajobrazu rolniczego
Authors: KURUS JOANNA , PODSTAWKA-CHMIELEWSKA ELŻBIETA
Published: April 2022

The paper presents some elements of Melampyrum arvense biology in plant community in the region of the Chełm Hills. The research was conducted on the roadsides, where rich stations of Melampyrum arvense were found, as well as in the neighbouring fields, of cereals (winter wheat and rye). Phytosociological records by Braun-Blanquet method were done in 2006 and 2007 on the rendzina soil in three localities: Anusin, Bezek and Mogielnica. At the same time from each station 30 plants were chosen to determine the height of plants and the number of offshoots. The result of the research carried out in the roadsides and corn-field shows that Melampyrum arvense occurs in the rich floral phytocenosis. Melampyrum arvense finds better conditions for growth and development in the habitats of roadsides than in agrocenosis. Melampyrum arvense plants from roadsides were higher and had more shoots than plants from segetal phytocenosis. Presumably agricultural chemicalization does not favour Melampyrum arvense appearing in segetal phytocenosis, which results in the lack of its presence in cereal plants far from the roadsides. But some features such as purple and yellow, thick inflorescence, long period of flowering and growing in large concentration let us include Melampyrum arvense into the species group which besides increasing biodiversity of native flora, influence the colour of agricultural landscape.
Zmienność geochemiczna siedlisk łąkowych doliny Bugu w rejonie Dubienki
Authors: BOROWIEC JÓZEF , URBAN DANUTA , MIKOSZ ANNA IWONA
Published: April 2022

The paper presents results of research on the meadows of the Bug River Valley, in the Skryhiczyn-Dubienka section. The study mainly concerned the geochemical variability of soils and meadow vegetation. In 1999, 14 soil pits were made in hay-growing fragments of the meadows, with 42 samples collected for laboratory tests. At the same points, samples (14) of the vegetation (hay, 1st swath) were collected. In the collected material (soil, hay), the total content of P, K, Ca, Mg, Fe, Mn, Cu, Zn, Pb was assayed with the method developed by Sapek & Sapek (1997). Moreover, in the soil samples, pH in H2O and KCl was assayed electrometrically and the Corganic content was determined with the Tiurin method, CaCO3 – using the Scheibler apparatus. The examined meadow soils of the Bug River Valley make at present a differentiated typological mosaic of valley soils (humus muds, black earths, bog soils) at various stages of development (degradation) and geochemical variability. The above scheme has been proved to a significant extent by the laboratory test results. This applies in particular to the differentiated humus content (2–5% of C-organ.), variability or a total absence of CaCO3 (0–6%) and progressing soil acidification (pH 5.4–7.4). Wherever there are volumes of organic substance, exchangeable alkalis are sufficient and pH is high, P, Ca, Mg, Fe and some microelements (Cu, Zn, Pb) are more intensively absorbed in the soil. Under conditions of scarcity of alkaline components (Ca) and progressing acidification, most components are activated and washed deep into the profile. This applies in particular to alkaline components and iron. 

Monovalent elements (K, Na), as well as some other, more mobile ones, are poorly absorbed, especially in humus soil, but easily collected by plants or transported by water deep into the profile.

Published: April 2022

The aim of the study was to determine the effect of Bromus sterilis seed burying, different day/night temperatures and also different water pH of the subsoil on B. sterilis  germination. Moreover, the weed thresholds in winter wheat cultivation were defined in these studies. B. sterilis become a serious problem in winter sown cereals and therefore the studies connected with the weed distribution and weed biology are necessary.

Results show that B. sterilis seeds buried at the 1.5 cm depth were characterized by the best and the earliest germination. Strong reduction of B. sterilis seeds germination was observed at the 10 cm depth seed burying. Range of tested day/night temperatures and water pH did not affect the seeds germination; however, differentiated speed of this process was observed. Increasing B. sterilis infestation has a significant effect on such parameters as ears number per sq. m., weight of 1000 grains and winter wheat grain yield.
Produkcja biomasy przez Chenopodium album L. w jęczmieniu jarym odchwaszczanym chemicznie zredukowanymi i zalecanymi dawkami herbicydów
Authors: KRAWCZYK ROMAN
Published: April 2022

The aim of the work was to determine the influence of reduced doses herbicide and spring barley density on seed and biomass production of Chenopodium album L. The field experiments were carried out in the years 2000, 2002–2003 on podsolic soil made from heavy loamy sand. There were two factors in the experimental scheme: I. Seeding rate of spring barley (200, 100 seeds m-2), II. Herbicide rate and time of herbicide application. Herbicides were applied at the recommended rate (3/3) and at 2/3 and 1/3 of the recommended dose. Three doses of herbicides were applied at the beginning of tillering (BBCH 21) and at the end of tillering of spring barley (BBCH 29). Competition between spring barley and Chenopodium album L. was studied in two experiments. The first field experiment was carried out with tribenuron methyl (Granstar 75 WG) and the second one with a mixture of mecoprop + MCPA + dicamba (Chwastox Trio 540 SL). Herbicides were applied at the recommended rate (3/3) and at 2/3 and 1/3 of the recommended dose. Weed biomass and seed production of Chenopodium album was reduced when spring barley was sown with the higher seeding rate. The average seed mass on the untreated plots was higher at low crop density (88.5 g·m-2) than the seed mass at optimal density of spring barley (44.4 g·m-2).

Reduction of Chenopodium album seeds production was observed after application of herbicides at the BBCH 21 of compared spring barley with the late application. Chenopodium album seed mass collected from the plots treated with mecoprop + MCPA + dicamba was higher than the mass collected from the plots treated with tribenuron methyl.

Biologia i cykl życiowy Chenopodium album L. na plantacjach ekologicznych zbóż i w warunkach doświadczalnych
Authors: Dostatny Denise F. , Małuszyńska Elżbieta
Published: April 2022

W latach 2005–2006 badano występowanie komosy na ekologicznych plantacjach nasiennych zbóż. Analizowano zebrany materiał nasienny pod względem liczby nasion tego gatunku. Nasiona Chenopodium album poddano kiełkowaniu. Stwierdzono, że najlepsze warunki kiełkowania to czas wstępnego chłodzenia 7 dni, stała temperatura kiełkowania 20°C i oświetlenie. Na podstawie obserwacji w warunkach szklarniowych wykazano, że faza kwitnienia C. album rozpoczynała się od 49 do 65 dnia od początku kiełkowania. Początek fazy owocowania następował po około 30 dniach od rozpoczęcia kwitnienia. Kwitnienie komosy rozpoczynało się niezależnie od wysokości rośliny. Warunki kiełkowania nie miały wpływu na liczbę diaspor wydanych w następnym pokoleniu. Stwierdzono, że około 40% nasion z jednego osobnika jest zdolne do kiełkowania bezpośrednio po dojrzewaniu.

Published: April 2022

W latach 2005–2006 w Stacji Doświadczalnej Katedry Sadownictwa Akademii Rolniczej w Szczecinie, w miejscowości Rajkowo, przeprowadzono doświadczenie wegetacyjne, którego celem była ocena wpływu dolistnego dożywiania Alkalinem potasowym z krzemem na niektóre cechy fizjologiczne truskawki odmiany Senga Sengana. Określono zawartość barwników asymilacyjnych w liściach, powierzchnię pojedynczego liścia, sumaryczną powierzchnię asymilacyjną liści z pojedynczej rośliny oraz liczbę liści. Nie stwierdzono istotnego wpływu dokarmiania dolistnego Alkalinem potasowym z krzemem na zawartość chlorofilu a, b, całkowitego oraz karotenoidów w liściach. Dokarmianie dolistne nie wpłynęło istotnie na wielkość sumarycznej powierzchni asymilacyjnej liści pojedynczej rośliny oraz powierzchnię pojedynczego liścia. Rośliny dokarmiane dolistnie i kontrolne charakteryzowały się także zbliżoną liczbą liści.
Field trials on grain maize cultivation technologies in 2004, 2005 and 2006
Authors: Šařec Petr , Šařec Ondřej , Gil Katarzyna
Published: April 2022

The paper presents the results of field studies that assess the influence of various technologies of maize-for-grain cropstand establishment on not only its yield, but also on labour and fuel consumption, and individual cost components. The field studies were carried out since the year 2004 in all maize-growing regions of the Czech Republic. Farm businesses are monitored that perform either a conventional technology of soil cultivation comprising ploughing or a reduced-tillage technology. The studies showed no significant differences in grain yields between both technologies in question. On the other hand, labour consumption demonstrated highly significant differences, i.e. 56.2 % in favour of reduced-tillage. Significant differences in favour of reduced-tillage technology were proved as well with regard to fuel consumption, machinery and total costs.

Authors: Tratwal Anna
Published: April 2022

W pracy przedstawiono wyniki doświadczeń nad wpływem uprawy odmian pszenicy ozimej w formie mieszanek w połączeniu z różnymi kombinacjami chemicznej ochrony na nasilenie występowania objawów mączniaka prawdziwego oraz plon. Badania przeprowadzono w ciągu dwóch sezonów wegetacyjnych 2005/2006 i 2006/20007. Ścisłe doświadczenia polowe założono z dwoma odmianami pszenicy ozimej (Finezja i Clever) z różnymi typami genetycznej odporności na mączniaka prawdziwego wysianymi w siewach czystych i ich mieszance. W do-świadczeniu stosowano różne kombinacje chemicznej ochrony. Badania przeprowadzono w dwóch miejscowościach zróżnicowanych pod względem warunków glebowych i meteorologicznych, tj. w Polowej Stacji Doświadczalnej Instytutu Ochrony Roślin Winna Góra (woj. wielkopolskie) i Hodowli Roślin Smolice – Grupa IHAR Oddział Bąków (woj. opolskie).W badaniach stwierdzono redukcję nasilenia występowania mączniaka prawdziwego na po-ziomie 20–60% w mieszance w porównaniu z siewami czystymi w zależności od kombinacji ochrony. Przyrosty plonów w mieszankach notowano na poziomie 0,4 do 3,0 dt/ha.
Wpływ dolistnego nawożenia rzepaku ozimego molibdenem na zawartość tego pierwiastka w nasionach
Authors: Stanisławska-Glubiak Ewa
Published: April 2022

Przeprowadzono 33 ścisłe doświadczenia polowe zlokalizowane na polach produkcyjnych rzepaku ozimego na terenie 8 województw w kraju, w których badano efekt dolistnego nawożenia rzepaku molibdenem. Stosowano dawki: 30, 60 i 120 g Mo · ha–1 w formie wodnego roztworu molibdenianu amonu w 2 terminach: wiosną, kilka dni po ruszeniu wegetacji, oraz na początku formowania łodygi. Dolistne nawożenie rzepaku molibdenem w przypadku niskiej jego zawartości w nasionach z obiektów kontrolnych powodowało wzrost koncentracji tego składnika o 39–56%, w zależności od dawki i terminu stosowania molibdenu. W grupie doświadczeń z dwukrotnie wyższą zawartością molibdenu w nasionach z obiektów kontrolnych nie stwierdzono zmiany koncentracji tego składnika wskutek nawożenia Mo.
Wpływ etefonu na komponenty plonu linii izogenicznych pszenicy zwyczajnej (Triticum aestivum L.) cv. ’Bezostnaja’ z genami Rht
Authors: Kowalczyk Krzysztof , Jakubczak Agnieszka , Nowak Michał
Published: April 2022

W pracy określono wpływ etefonu na komponenty plonu linii izogenicznych pszenicy zwyczajnej: ‘Bezostnaja’ Rht-B1a (wysokie – kontrola), ‘Bezostnaja’ Rht-B1b, ‘Bezostnaja’ Rht-B1d i ‘Bezostnaja’ Rht-B1e. Linie te badano w latach 2000/2001–2002/2003 w Gospodarstwie Doświadczalnym w Czesławicach. Uzyskane wyniki badań poddano analizie wariancji. Na pod-stawie trzyletnich badań stwierdzono, że zastosowanie etefonu powodowało redukcję wysokości roślin w badanych liniach izogenicznych. Największą redukcję wysokości roślin obserwowano w liniach ‘Bezostnaja’ Rht-B1a i ‘Bezostnaja’ Rht-B1d, co przyczyniło się istotnie do zmniejszenia wylegania w tych liniach. W krótkosłomych liniach pszenicy zastosowanie regulatorów wzrostu zawierających etefon nie wpływało niekorzystnie na liczbę ziarniaków w kłosie. Zastosowanie preparatów zawierających ten związek w liniach ‘Bezostnaja’ Rht-B1b i ‘Bezostnaja’ Rht-B1d powodowało najczęściej wzrost wartości tej cechy. Wykazano ponadto niewielki wpływ etefonu na masę 1000 ziarniaków oraz plon ziarna z poletka analizowanych linii izogenicznych.
Reakcja 10 odmian pszenicy ozimej na dokarmianie dolistne borem
Authors: KORZENIOWSKA JOLANTA
Published: April 2022

W latach 2003–2006 przeprowadzono 3 ścisłe doświadczenia polowe z nawożeniem dolistnym 10 odmian pszenicy ozimej borem. Bor stosowano w postaci kwasu borowego w ilości 175 g · ha-1. Dokarmianie dolistne spowodowało istotny wzrost plonów ziarna czterech z 10 badanych odmian. Uzyskane średnie zwyżki plonów wahały się od 9 do15%. Wymagania pokarmowe sześciu pozostałych odmian w stosunku do B były znacznie niższe. Chociaż dolistna aplikacja B powodowała u tych odmian wzrost jego zawartości w pędach, to nie reagowały one zwyżką plonu na nawożenie tym pierwiastkiem.
Reakcja wybranych gatunków pszenicy ozimej na termin siewu
Authors: Szumiło Grzegorz , Rachoń Leszek
Published: April 2022

Badania polowe przeprowadzono w latach 2005–2007 na terenie Gospodarstwa Doświadczalnego Felin AR w Lublinie. Ich celem było określenie wpływu dwóch terminów siewu: optymalnego i opóźnionego (o 2 tygodnie) na plonowanie, elementy struktury plonu oraz wybrane parametry jakościowe ziarna ozimych form pszenicy orkisz (Triticum spelta L.), twardej (Triticum durum Desf.) i zwyczajnej (Triticum aestivum L.). Opóźnienie terminu siewu ograniczyło plonowanie pszenicy orkisz, twardej i zwyczajnej średnio 17,3%. Wynikało to głównie z istotnego spadku liczby kłosów pszenicy wysiewnej w terminie opóźnionym. Pszenica ozima siana w terminie optymalnym w porównaniu z sianą z dwutygodniowym opóźnieniem dawała ziarno o istotnie większej gęstości w stanie zsypnym. Plon pszenicy orkisz był niższy średnio o 9,2% w porównaniu z plonem pszenicy zwyczajnej. Pszenica twarda plonowała istotnie niżej od pszenicy orkisz i pszenicy zwyczajnej odpowiednio o 14,5% i 22,4%, za sprawą istotnie mniejszej obsady kłosów. Największą szklistością cechowało się ziarno pszenicy twardej, a najmniejszą szklistość ziarna stwierdzono u pszenicy orkisz.
Wpływ terminu zakładania plantacji i odmładzającego przeorywania oraz stosowania Asahi SL w uprawie mięty pieprzowej
Authors: Kołodziej Barbara
Published: April 2022

Celem trzyletniego doświadczenia polowego ulokowanego na glebie lessowej było zbadanie wpływu terminu zakładania plantacji i stosowania Asahi SL (Atoniku SL) na plony i jakość surowca Mentha × piperita L. W eksperymencie porównywano dwa terminy zakładania lub odmładzającego przeorywania plantacji (jesienny – X i wiosenny – IV) oraz efekty stosowania wykonywanego dwukrotnie w ciągu roku oprysku 0,1% Asahi SL. Otrzymane wyniki wskazują, że do zakładania plantacji z równym powodzeniem można stosować obydwa porównywane terminy zakładania, a w dalszych latach uprawy odmładzające przeorywania plantacji. Naturalny regulator wzrostu – Asahi SL sprzyja natomiast zwiększeniu zarówno zawartości olejku eterycznego, jak i plonów surowca, a zatem może być polecany w uprawie mięty pieprzowej.
Wpływ stosowania wybranych nawozów dolistnych na plono-wanie żmijowca babkowatego (Echium plantagineum L.)
Authors: Król Beata
Published: April 2022

W dwuletnim doświadczeniu polowym oceniano wpływ stosowania wybranych nawozów dolistnych (Insol 5, Mikrosol U, Agrosol R, Ekolist S) oraz regulatora wzrostu Asahi SL na plonowanie żmijowca babkowatego (Echium plantagineum L.). Zastosowane nawozy dolistne wpłynęły korzystnie na wysokość roślin oraz stymulowały tworzenie pędów bocznych i masy nadziemnej. Spośród badanych preparatów jedynie Asahi SL spowodował znaczny wzrost plonowania nasion, natomiast pozostałe nawozy dolistne nie wykazały istotnego wpływu na plony żmijowca. Stwierdzano nieznaczne obniżenie zawartości tłuszczu w nasionach żmijowca pod wpływem dokarmiania dolistnego.
Podcasting about yourself and challenging norms: An investigation of independent women podcasters in Denmark
Authors: Adler Berg Freja Sørine
Published: April 2022

This article investigates why and how women use independent podcasting and social media platforms to challenge norms afflicting their own personal lives. Extending previous studies of independent podcasting as a tool of empowerment, this article analyses semi-structured interviews with the hosts of two podcasts: the mental health and personal journals podcastA Seat at The Tableand the parenting podcastOur Different Family[Vores Anderledes Familie]. The podcasts are norm-challenging but, at the same time, illustrative of a gendered podcasting sphere in which women primarily podcast about what has traditionally been considered female domains, such as mental health, personal journals, and parenting. The study finds that podcasting’s lack of visuals and unrestricted, conversational format allow for creating and distributing in-depth realisations about personal norm-challenging issues. Simultaneously, it finds that the participatory affordances of social media platforms are essential for receiving feedback, content ideas, and emotional support from like-minded listeners when the podcasters challenge oppressive norms.
