The Effects of Dietary Crude Protein Level on Ammonia Emissions from Slurry from Lactating Holstein-Friesian Cows as Measured in Open-Circuit Respiration Chambers
Authors: Katongole Constantine Bakyusa , Yan Tianhai
Published: May 2022

The effect of dietary crude protein (CP) level on ammonia (NH3) emissions from slurry from lactating Holstein-Friesian cows was studied. Twenty-four-hour total collections of faeces and urine were made from 24 lactating Holstein-Friesian cows fed four total mixed rations containing 141, 151, 177, and 201 g CP/kg DM (6 cows/diet). The collected urine and faeces from each cow were combined to form 2 kg duplicate slurry samples (weight/weight; fresh basis) according to the proportions in which they were excreted. NH3 emissions from the slurry samples were measured, during 0–24 and 24–48 h intervals in six open-circuit respiration chambers maintained at two temperatures (8 or 18 °C). NH3 emissions for the 0–24 and 0–48 h intervals, as well as the average daily emissions, increased linearly with increasing dietary CP level. Increasing the temperature from 8 to 18 °C positively affected NH3 emissions, but only for the 0–24 h interval. In situations where direct measurements are impossible, NH3 emissions from slurry can be predicted accurately using equations based on dietary CP level supported by either urinary nitrogen, faeces nitrogen, or both. In summary, increasing dietary CP level linearly increased average daily NH3 emissions from slurry, with a 5.4 g increase for each 10 g increase in dietary CP.

Published: May 2022

The additional internal forces in vertical members caused by prestressed tendons are typically overlooked in the design of post-tensioned prestressed concrete. A calculation method for additional internal forces in single-story multi-span prestressed concrete frame columns based on equivalent lateral stiffness is proposed in this paper. The slope-deflection equation for the bar element was presented using Timoshenko beam assumptions, taking into account the influence of shear and bending deformations. Subsequently, the concept of equivalent lateral stiffness and calculation equations were proposed. On this basis, the equations of the third shear and third bending moment for single-story multi-span prestressed frame columns were established. Furthermore, applying engineering examples, the method in this study was verified by ABAQUS software and previous methods. The results show that theoretical values and FEA results are in good agreement. Compared to previous methods, the method in this paper is more accurate and widely applicable. In addition, the stretching plan has a significant path effect and time-varying effect on the interlayer distribution of the third moment. It should be considered at the building stage to check the calculation of the frame column.
The Evaluation of Quality of the Co-Firing Process of Glycerine Fraction with Coal in the High Power Boiler
Authors: Kozdrach Rafal , Stepien Andrzej
Published: May 2022

The article presents the test results of the co-firing process of a glycerine fraction derived from the production of liquid biofuels (fatty acid methyl esters) with coal. The test was performed in industrial conditions using a steam boiler with a capacity of approx. 2 MW in one of the building materials manufacturing facilities. The process of co-firing a mixture of a 3% glycerine fraction and eco-pea coal was evaluated. The reference fuel was eco-pea coal. The combustion process, composition and temperature of exhaust gases were analyzed. Incorrect combustion of glycerine fraction may result in the emission of toxic, mutagenic, and carcinogenic substances, including polycyclic aromatic hydrocarbons. During the test of the combustion process of a mixture of glycerine fraction and eco-pea coal, a decrease in the content of O2, CO, and NOx was observed as well as an increase in the content of H2, CO2, and SO2 in the fumes and growth of temperature of exhaust gases in relation to the results of combustion to eco-pea coal. Reduced content of carbon monoxide in exhaust gases produced in the combustion could be caused by the high temperature of the grate or by an excessive amount of oxygen in the grate. The higher content of oxygen in glycerine changes the value of excess air coefficient and the combustion process is more effective. The bigger content of sulfur dioxide in burnt fuels containing the glycerine fraction could be caused by the presence of reactive ingredients contained in the glycerine fraction. The reduced content of nitrogen oxides in exhaust gases originating from the combustion of a fuel mixture containing a fraction of glycerine could be caused by lower content of nitrogen in the glycerine fraction submitted to co-firing with coal and also higher combustion temperature and amount of air in the combustion chamber. The increased content of carbon dioxide in exhaust gases originating from the combustion of fuel mixture containing glycerine fraction could be caused by the influence of glycerine on the combustion process. The increase of hydrogen in the glycerine fraction causes the flame temperature to grow and makes the combustion process more efficient.
Rabphilin-3A Drives Structural Modifications of Dendritic Spines Induced by Long-Term Potentiation

Published: May 2022

The interaction of Rabphilin-3A (Rph3A) with the NMDA receptor (NMDAR) in hippocampal neurons plays a pivotal role in the synaptic retention of this receptor. The formation of a Rph3A/NMDAR complex is needed for the induction of long-term potentiation and NMDAR-dependent hippocampal behaviors, such as spatial learning. Moreover, Rph3A can also interact with AMPA receptors (AMPARs) through the formation of a complex with myosin Va. Here, we used a confocal imaging approach to show that Rph3A overexpression in primary hippocampal neuronal cultures is sufficient to promote increased dendritic spine density. This morphological event is correlated with an increase in GluN2A-containing NMDARs at synaptic membranes and a decrease in the surface levels of GluA1-containing AMPARs. These molecular and morphological modifications of dendritic spines are sufficient to occlude the spine formation induced by long-term potentiation, but do not prevent the spine loss induced by long-term depression. Overall, our results demonstrate a key role for Rph3A in the modulation of structural synaptic plasticity at hippocampal synapses that correlates with its interactions with both NMDARs and AMPARs.
Salivary Progesterone Levels in Female Patients with a History of Idiopathic Scoliosis: A Retrospective Cross-Sectional Study
Authors: Morningstar Mark W. , Strauchman Megan N.
Published: May 2022

Idiopathic scoliosis is a condition characterized by a three-dimensional curvature of the spine. However, in addition to the spinal curvature, it has also been reported that patients with idiopathic scoliosis can display other abnormal physiologic parameters, such as hormone imbalances, genetic variants, and micronutrient deficiencies. The present study evaluates the salivary progesterone levels from a historical cohort of patients seeking treatment at a single integrative medicine clinic. A group of female patients with a history of idiopathic scoliosis is compared to a group of non-scoliosis female patients. Salivary progesterone levels were 49% higher in non-scoliosis patients compared to the scoliosis group (p < 0.05). When compared by the menstrual cycling status, non-scoliosis females had a 60% higher average progesterone level, while the progesterone level among non-cycling, non-scoliosis females was 39% higher than non-cycling scoliosis females. These results suggest a potential relationship between salivary progesterone and idiopathic scoliosis among female patients.

Published: May 2022

Painting a V-shaped surface, which is widely found in various facilities and equipment, often results in poor coating quality, which may be caused by an insufficient understanding of film-forming characteristics and mechanism. In this study, computational fluid dynamic (CFD) simulations were carried out for in-depth research on the film-forming characteristics and mechanism of painting V-shaped surfaces. The mathematical model of film formation was established with the Euler–Euler method, and the unstructured grids and adaptive-mesh refinement were adopted to discretize the computational domain. By solving the model, the coating thickness distribution law and flow-field characteristics of spraying a V-shaped surface were obtained. When painting a V-shaped surface with an angle less than 180°, the coating thickness distribution appeared as two peaks, instead of the single peak that appeared when painting a flat wall. As the V-shaped angle decreased, the coating thickness became thinner. The peak position gradually shifted to both sides, and the thickness distribution became wider. Analysis of the spray flow-field characteristics revealed the thickness distribution mechanism, by whichthe geometric characteristics of the V-shaped surface changed the near-wall distribution of the flow field. When the V-shaped angle decreased, the pressure peak at the center of the V-shaped surface and the eccentric pressure peaks that formed on both sides increased. The near-wall paint fluid was confined between the central pressure peak and the off-center pressure peak, resulting in paint droplets depositing between the pressure peaks and double-peak distribution of the coating thickness forming on the V-shaped surface. The spraying experiments verified the correctness of the numerical simulations, film-forming characteristics, and corresponding mechanism, which are of great significance for efficient and high-quality spraying on V-shaped surfaces.

Published: May 2022

Producing hydrogen via water electrolysis could be a favorable technique for energy conversion, but the freshwater shortage would inevitably limit the industrial application of the electrolyzers. Being an inexhaustible resource of water on our planet, seawater can be a promising alternative electrolyte for industrial hydrogen production. However, many challenges are hindering the actual application of seawater splitting, especially the competing reactions relating to chlorine at the anode that could severely corrode the catalysts. The execution of direct seawater electrolysis needs efficient and robust electrocatalysts that can prevent the interference of competing reactions and resist different impurities. In recent years, researchers have made great advances in developing high-efficiency electrocatalysts with improved activity and stability. This review will provide the macroscopic understanding of direct seawater splitting, the strategies for rational electrocatalyst design, and the development prospects of hydrogen production via seawater splitting. The nonprecious metal-based electrocatalysts for stable seawater splitting and their catalytic mechanisms are emphasized to offer guidance for designing the efficient and robust electrocatalyst, so as to promote the production of green hydrogen via seawater splitting.
Quid Pro Quo CSR and Trade Liberalization in a Bilateral Monopoly
Authors: Chen Shih-Shen , Tsai Chien-Shu , Chen Chen
Published: May 2022

We construct a dynamic bilateral monopoly game to analyze the bargaining between a foreign manufacturer and a domestic retailer regarding the wholesale price and explain the foreign upstream firm’s corporate social responsibility (CSR) initiative and its economic impacts on the domestic market. Under free trade, the foreign upstream firm’s CSR initiative realizes improvements in consumer surplus and social welfare in the home country. A “win–win–win” strategy exists, as the foreign manufacturer has more of an incentive to implement CSR when the government implements a strategic trade policy. The consumer-friendly action implemented by the foreign upstream firm leads to adequate consumer welfare and social welfare, which mitigates the government’s political hostility. With the high bargaining power of the foreign upstream firm and the low weight of the consumer-friendly upstream firm, the government should set a higher tariff rate for the foreign upstream firm to extract rent and enhance social welfare.
Three-Phase Three-Dimensional Electrochemical Process for Efficient Treatment of Greywater
Authors: Li Weiyang , Wang Wei , Zhang Peng
Published: May 2022

Water shortages around the world have intensified the search for substitute sources. Greywater can serve as a solution for water requirements. Compared to two-dimensional electrochemical processes for water treatment, the addition of particle activated carbon enhances the conductivity and mass transfer or the adsorption of pollutants in a three-dimensional (3D) electrochemical process. The large specific surface areas of these particles can provide more reactive sites, resulting in a higher removal efficiency. In this study, the treatment of greywater by the electro-Fenton (E-Fenton) method was carried out in a 3D electrolytic reactor. The effects of the operating conditions, such as electrode spacing, applied voltage, treatment time, and activated carbon loading, on the efficacy of the E-Fenton process were investigated, and the corresponding optimum conditions were found to be 7 cm, 9 V, 2 h, and 10 g. The results showed that CODCr removal of greywater treated using the 3D electrochemical process was 85%. With the help of the Box–Behnken experiment design and the response surface methodology, the parameters were optimized to determine the optimal conditions. The results of the response surface analysis were consistent with the experimental results. The above findings illustrate that the proposed three-phase 3D electrochemical process is feasible for the efficient treatment of greywater.

Published: May 2022

Fe-based amorphous powder cores (AMPCs) were prepared from FeSiBCr amorphous powders with phosphate–resin hybrid coating. The high-frequency magnetic properties of AMPCs annealed at different temperatures were systematically studied. After annealing at low temperatures, the effective permeability and core loss improved due to the internal stress of the powder cores being released. The sample annealed at 480 °C exhibits the lowest hysteresis loss of about 29.6 mW/cm3 at 800 kHz as well as a maximum effective permeability of 36.4, remaining stable until 3 MHz, which could be useful for high-frequency applications.

Published: May 2022

Respiration monitoring is vital for human health assessment. Humidity sensing is a promising way to establish a relationship between human respiration and electrical signal. This paper presents a polyimide-based film bulk acoustic resonator (PI-FBAR) humidity sensor operating in resonant frequency and reflection coefficient S11 dual-parameter with high sensitivity and stability, and it is applied in real-time human respiration monitoring for the first time. Both these two parameters can be used to sense different breathing conditions, such as normal breathing and deep breathing, and breathing with different rates such as normal breathing, slow breathing, apnea, and fast breathing. Experimental results also indicate that the proposed humidity sensor has potential applications in predicting the fitness of individual and in the medical field for detecting body fluids loss and daily water intake warning. The respiratory rates measured by our proposed PI-FBAR humidity sensor operating in frequency mode and S11 mode have Pearson correlation of up to 0.975 and 0.982 with that measured by the clinical monitor, respectively. Bland–Altman method analysis results further revealed that both S11 and frequency response are in good agreement with clinical monitor. The proposed sensor combines the advantages of non-invasiveness, high sensitivity and high stability, and it has great potential in human health monitoring.
Sulfate Sources Required for Thermochemical Sulfate Reduction in Dolostone Reservoirs in the Upper Permian Changxing Formation, Yuanba Gas Field, Sichuan Basin, China: Insights from the Origin of Celestite
Authors: Yu Xinya , Zhu Dancheng , Zou Huayao , Hao Fang
Published: May 2022

Thermochemical sulfate reduction (TSR) commonly occurred in the dolostone reservoirs of the Upper Permian Changxing Formation (P3c) in the Yuanba (YB) gas field, Sichuan Basin, yet controversy remains regarding the source of sulfate required for TSR. To trace the source of the sulfate, sulfur and strontium isotopic compositions were measured for three diagenetic celestite (SrSO4) samples found in the P3c dolostone reservoirs in the YB gas field. In addition, the sulfur isotopic compositions of Carbonate-associated sulfates (CAS) from the P3c carbonates and spheroidal pyrites in dolomicrites from the P/T boundary (PTB) in the YB gas field were measured for comparative studies. The results show that the sulfur isotopic compositions of celestites are significantly heavier than those of the contemporaneous seawater, and these celestites have strontium isotopic values consistent with those of the host dolostones and contemporaneous seawater. The −33.68‰ fractionation in average δ34S values between pyrites and celestites indicated that their formation was likely to be related to bacterial sulfate reduction (BSR). During the P/T extinction event that accompanied the end-Permian regression, the reflux of brine directly precipitated 34S-rich celestites in the fractures and vugs of the dolostone reservoirs due to the BSR and the evaporation of seawater. These 34S-rich celesites and associated pore fluids provide a new explanation for the source of sulfate required for the late TSR.

Published: May 2022

Vermiculite two-dimensional mixed-layer interstratified structures are a very attractive material for catalysis and photocatalysis. The iron-containing vermiculite from the Palabora region (South Africa) and its samples, which calcined at 500 and 700 °C, were studied in comparison with the α-Fe2O3 nanoparticles/vermiculite composites for the first time as photocatalysts of methanol decomposition, which is an organic pollutant and an efficient source for hydrogen production. The aim of the work was to characterize their structural properties using X-ray fluorescence, X-ray diffraction, infrared spectroscopy, nitrogen physisorption, diffuse reflectance UV-Vis spectroscopy and photoluminescence spectroscopy to explain the photocatalytic effects. The photocatalytic test of the samples was performed in a batch photoreactor under UV radiation of an 8W Hg lamp. The photocatalytic activity of vermiculite–hydrobiotite–mica-like layers at different water hydration states in the interstratified structure and the substitution ratio of Fe(III)/Al in tetrahedra can initiate electrons and h+ holes on the surface that attack the methanol in redox processes. The activity of α-Fe2O3 nanoparticle photocatalysts stems from a larger crystallite size and surface area. The hydrogen production from the methanol–water mixture in the presence of vermiculites and α-Fe2O3 nanoparticles/vermiculite composites was very similar and higher than the yield produced by the commercial TiO2 photocatalyst Evonik P25 (H2 = 1052 µmol/gcat.). The highest yield of hydrogen was obtained in the presence of the Fe/V–700 composite (1303 µmol/gcat after 4 h of irradiation).

The W–Cu composites with nanosized grain boundaries and high effective density were fabricated using a new fast isostatic hot pressing method. A significantly faster method was proposed for the formation of W–Cu composites in comparison to the traditional ones. The influence of both the high temperature and pressure conditions on the microstructure, structure, chemical composition, and density values were observed. It has been shown that W–Cu samples have a polycrystalline well-packed microstructure. The copper performs the function of a matrix that surrounds the tungsten grains. The W–Cu composites have mixed bcc-W (sp. gr. Im 3¯ m) and fcc-Cu (sp. gr. Fm 3¯ m) phases. The W crystallite sizes vary from 107 to 175 nm depending on the sintering conditions. The optimal sintering regimes of the W–Cu composites with the highest density value of 16.37 g/cm3 were determined. Tungsten–copper composites with thicknesses of 0.06–0.27 cm have been fabricated for the radiation protection efficiency investigation against gamma rays. It has been shown that W–Cu samples have a high shielding efficiency from gamma radiation in the 0.276–1.25 MeV range of energies, which makes them excellent candidates as materials for radiation protection.

Published: May 2022

Transition metal dichalcogenide-based quantum dots are promising materials for applications in diverse fields, such as sensors, electronics, catalysis, and biomedicine, because of their outstanding physicochemical properties. In this study, we propose bio-imaging characteristics through utilizing water-soluble MoS2 quantum dots (MoS2-QDs) with two different sizes (i.e., ~5 and ~10 nm). The structural and optical properties of the fabricated metallic phase MoS2-QDs (m-MoS2-QDs) were characterized by transmission electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, UV–vis absorption spectroscopy, and photoluminescence. The synthesized m-MoS2-QDs showed clear photophysical characteristic peaks derived from the quantum confinement effect and defect sites, such as oxygen functional groups. When the diameter of the synthesized m-MoS2-QD was decreased, the emission peak was blue-shifted from 436 to 486 nm under excitation by a He-Cd laser (325 nm). Density functional theory calculations confirmed that the size decrease of m-MoS2-QDs led to an increase in the bandgap because of quantum confinement effects. In addition, when incorporated into the bio-imaging of HeLa cells, m-MoS2-QDs were quite biocompatible with bright luminescence and exhibited low toxicity. Our results are commercially applicable for achieving high-performance bio-imaging probes.

Aluminum composites are preferred in many kinds of applications such as aviation, space, automotive, and marine, owing to their outstanding properties, high strength, and corrosion resistance. The main objective of the current study is to evaluate the mechanical properties of aluminum alloy 6061/titanium dioxide (micro-TiO2) microcomposite synthesized using the stir casting method. The effects of changes in stir casting parameters, such as stirring speed and tiring durations, were studied. Al6061 matrix was reinforced with micro-TiO2 particles with weight fractions of 1, 2, 3, 4, and 5 wt.%. Microstructural and chemical analyses were conducted to explore microstructural transformation resulting from the presence of the TiO2 microparticles. The mechanical characteristics were evaluated, and the results showed a considerable enhancement in the mechanical strength and hardness resulting from the incorporation of micro-TiO2 into Al606. The additions of 2 wt.% and 5 wt.% of micro-TiO2 recorded the highest ultimate tensile strength and hardness, respectively.

Autoimmune hemolytic anemia (AIHA) is a rare disorder characterized by the autoantibody-mediated destruction of red blood cells, and treatments for it still remain challenging. Traditional first-line immunosuppressive therapy, which includes corticosteroids and rituximab, is associated with adverse effects as well as treatment failures, and relapses are common. Subsequent lines of therapy are associated with higher rates of toxicity, and some patients remain refractory to currently available treatments. Novel therapies have become promising for this vulnerable population. In this review, we will discuss the mechanism of action, existing data, and ongoing clinical trials of current novel therapies for AIHA, including B-cell-directed therapy, phagocytosis inhibition, plasma cell-directed therapy, and complement inhibition.

Published: May 2022

Protein is one of the major macronutrients essential in human nutrition. Protein sources especially animal sourced proteins are expensive, thus much work has been carried out to explore alternative protein sources. Seaweeds, or macroalgae, are emerging as one of the alternative protein sources. They are rich in protein with an excellent amino acid profile comparable to the other conventional protein sources. Seaweed protein contains bioactive components, such as free amino acids, peptides, lectins, and phycobiliproteins, including phycoerythrin and phycocyanin, among others. Seaweed proteins have been proved for their antihypertensive, antidiabetic, antioxidant, anti-inflammatory, antitumoral, antiviral, antimicrobial, and many other beneficial functional properties. Therefore, seaweed proteins can be a natural alternative source for functional food development. This paper discusses the compositional and nutritional aspects of seaweed protein, protein extraction techniques, functional properties of various seaweed proteins, as well as their safety for new product development and functional food applications.

Bu farkı oluşturan başlıca nedenin öğretim programlarının uygulanma süreçlerindeki farklılıklar olduğu bulgusuna ulaşılmıştır. Araştırma sonucuna göre Türkiye’de öğretmen niteliklerini yükseltecek çalışmaların artırılması ve eğitimde günümüzün vazgeçilmez parçası olan teknolojinin matematik öğretim programlarındaki yerinin genişletilmesi gerekmektedir.

Mevcut araştırmanın amacı Türkiye’de yürütülen öğretimsel liderlik konulu lisansüstü tezlerdeki eğilimi ortaya koymaktır. Bu bağlamda, YÖK Ulusal Tez Merkezi’ndeki açık erişimli lisansüstü tezler araştırmanın evrenini oluşturmaktadır. “Öğretimsel lider” ve “öğretimsel liderlik” anahtar kelimeleri ile yapılan tarama sonucunda toplam 99 teze ulaşılmış; bununla birlikte araştırma ölçütlerini karşılayan 62 tez analize dahil edilmiştir. Alanyazında mevcut benzer çalışmalardan yararlanılarak bir tez inceleme formu oluşturulmuş ve kategorik çözümleme yöntemi ile veri analizi yürütülmüştür. Tezler türü (yüksek lisans veya doktora), yürütüldüğü yıl, yöntem, örneklem, örneklemin görev yaptığı okul düzeyi, kullanılan ölçme aracı, yürütüldüğü üniversite ve öğretimsel liderliğin ilişkilendirildiği değişken(ler) bağlamında incelenmiştir. Her bir kategoriye yönelik frekans ve yüzdelik değerler hesaplanmıştır. Elde edilen bulgular şu şekilde özetlenebilir. Öğretimsel liderlik konulu lisansüstü tezler çoğunlukla yüksek lisans düzeyinde ve nicel desendedir. Lisansüstü tezlerin yaklaşık üçte ikisinde veri öğretmenlerden toplanmıştır ve dörtte birinde örneklem grubu ilköğretim okullarında görev yapmaktadır. Son 10 yılda öğretimsel liderlik konulu tezlerde nicel bir artış gözlenmiştir. İncelenen tezlerin yaklaşık dörtte üçünde Şişman (1997) tarafından geliştirilen ölçme aracı kullanılmış ve öğretimsel liderlik en sık öğretmenlerin örgütsel bağlılığı ile ilişkilendirilmiştir. Son olarak, öğretimsel liderlik ile ilgili en fazla tezin Çanakkale Onsekiz Mart Üniversitesi’nde tamamlandığı belirlenmiştir. Elde edilen bulgulardan yola çıkarak bazı öneriler getirilmiştir.

Legislações ambientais têm sido rigorosas com as indústrias de refino de petróleo exigindo baixo teor de enxofre nos combustíveis. A hidrodessulfurização (HDS) é o principal processo empregado pelas refinarias na remoção de enxofre, porém tem um custo elevado, incentivando pesquisadores a buscar e desenvolver alternativas para complementar a HDS. O processo de adsorção tem surgido como solução. Neste trabalho foi avaliada a zeólita NaY modificada com metal de transição como adsorvente para remoção de enxofre presente na mistura modelo benzotiofeno em iso-octano que representa o combustível líquido. Os resultados de difração de raios X e BET indicaram a presença de formação de mesoporos no adsorvente NiO/NaY e que a cristalinidade intrínseca foi preservada após a incorporação do níquel. A remoção de enxofre foi de 67,5%, e a capacidade de adsorção foi de 17,7 mg.S.g-1 de adsorvente, evidenciando que o adsorvente tem potencial para adsorção do sulfurado.

Este trabalho objetivou utilizar o fertilizante à base de cálcio na cultura da soja, cultivar Agroeste AS 3730 IPRO como mais uma opção para a cultura da soja implantada na região do Centro-Oeste brasileiro. O experimento foi conduzido na safra dos anos agrícolas de 2019/2020, na Fazenda Panamá, município de Itumbiara, estado de Goiás, em sistema de cultivo convencional, implantado pelo Núcleo de Estudo e Pesquisa em Fitotecnia. A localidade apresenta como coordenadas geográficas, 18°18’24’’S de latitude e 49°30’41’’W de longitude e 554 m de altitude. Os parâmetros agronômicos “biometria das plantas” foram avaliados da seguinte maneira: a população foi analisada 30 dias após a germinação, estudos da biometria das plantas (parte aérea) foi realizado no ato da colheita, que são, número de ramificações, número de vagens de um grão, número de vagens de dois grãos, número de vagens de três grãos, número de vagens por planta, peso de mil grãos e produtividade em quilograma por hectare. Para avaliação da produtividade foram coletadas as plantas na área útil de cada parcela e efetuada a debulha manualmente com a pesagem dos grãos de cada parcela, e para o peso de mil grãos, foi utilizado uma bandeja para contagem dos mil grãos e o material pesado em balança de precisão. O delineamento experimental foi em blocos casualizados com um único fator, e as dose de FortCálcio utilizado foram em 7 níveis (T1: 0,0 Kg ha-1; T2: 200 Kg ha-1; T3: 250 Kg ha-1; T4: 300 Kg ha-1; T5: 350 Kg ha-1; T6: 400 Kg ha-1; T7: 450 Kg ha-1) e quatro repetições. Os dados foram analisados pelo programa SISVAR e submetidos à análise de variância, sendo as médias comparadas pelo teste Tukey, quando detectada significância para a ANOVA a p=0,05 de probabilidade para a comparação de médias. Os resultados mostraram uma diferença de 1.111 quilogramas ou seja 18,52 sacas de 60 quilos por hectare entre o melhor tratamento em comparação com a testemunha absoluta “dose zero” não sendo detectado pelo teste de médias, mas altamente perceptível ao bolso do produtor rural.
Relatos ecobio/gráficos de amozades: a terminologia como poética do pensamento e as literaturas subterrâneas / Eco-bio/graphic accounts of amozades: terminology as poetics of thought and underground literatures

O objetivo deste artigo é discutir a terminologia relato ecobio/gráfico na pesquisa (auto)biográfica em educação. Partimos do pressuposto de que pensar e repensar a terminologia seria um momento poético, como sugere Agamben, quando escreve que “As questões terminológicas são importantes na filosofia. Como disse uma vez um filósofo pelo qual tenho o maior respeito, a terminologia é o momento poético do pensamento” (AGAMBEN, 2009, p. 27). O trabalho, fruto da tese de doutorado intitulada “Formação-artista e territórios existenciais: biografização, escrita e experiência”, defendida em 2016 no Programa de Pós Graduação em Educação. Faculdade de Educação/UFC, cujo objetivo foi compreender, a partir da figuração de si nos relatos biográficos sobre como agentes sociais que não “dependem” do mercado editorial – a “ordem mercadológica dos livros” – para fazerem circular seus trabalhos artístico-literários formam-se “escritores/as” (processo de subjetivação, imersão de territórios existenciais). Tratava-se de evidenciar uma caudalosa produção de literaturas subterrâneas que banham e escorrem em bares, ruas, bosques, centros culturais, dentre outras zonas de encontro e partilha. Utilizando-me de referenciais do campo da pesquisa biográfica em educação (DELORY-MOMBERGER, 2008,2012, PINEAU, 2006; PASSEGGI, 2011, dentre outros), este artigo buscou discutir e justificar a terminologia utilizada em nossa pesquisa: relato eco/biográfico, uma vez que os relatos produzidos por nossos interlocutores de pesquisa sempre apontavam para relações de amozades (amor e amizade) construídas em suas andanças e perambulações artístico-literárias pelo mundo, construindo assim seus territórios existenciais/identitários.

Os decisores públicos e privados que trabalham com gerenciamento integrado de resíduos sólidos urbanos (GRSU) necessitam tomar decisões assertivas, no sentido de minimizar os impactos econômicos, ambientais e sociais. Para tal, existem ferramentas de apoio à decisão que permitem avaliar tais impactos. Uma das ferramentas é a Análise de Ciclo de Vida (ACV) nas suas versões: Ambiental (ACV), Econômica (AECV) e social (ACVS). O objetivo deste estudo é apresentar uma revisão bibliográfica da ACV nestas vertentes, aplicadas ao GRSU no Brasil e outros países em situações similares, tendo como enfoque os elos dos Serviços de Limpeza Urbana e Manejo de Resíduos Sólidos (SLUMRS). Como resultado percebe-se que enquanto a ACV ambiental encontra-se consolidada, os estudos que descrevem a avaliação dos impactos sociais e econômicos ainda são de menor expressão. Essa evidência demonstra que os três pilares da sustentabilidade não se encontram no mesmo nível de pesquisa, sendo essa uma oportunidade de explorar e harmonizar essas áreas.
Perspectivas e desafios da educação integral / Perspectives and challenges of integral education
Authors: Santos Matheus da Silva
Published: May 2022

O presente estudo aborda uma reflexão sobre a Educação integral e a organização do trabalho escolar, buscando a compreensão sobre a constituição de uma escola que prioriza a formação integral do ser humano. A partir de uma abordagem qualitativa constatou-se a importância desse modelo na atualidade, visto que, o mesmo engloba não somente os fatores educacionais, mas diversos aspectos ligados a aprendizagem. Entre os desafios para a implantação de uma educação integral está ligado ao modelo econômico que valoriza a quantidade e que traz no currículo tradicional sua essência maior que a fragmentação e uma das possibilidades para a implantação de um modelo de Educação Integral estão a utilização das metodologias ativas que permitem uma valorização da autonomia dos estudantes dando a estes um protagonismo maior e aos professores um papel de mediador do processo de ensino e aprendizagem e sobretudo dos estudantes que se tornam seres ativos e críticos.
