Opinião, ponto de vista e perspectiva - a construção da narrativa histórica e as questões de objetividade/verdade em História
Authors: Gago Marília 
Published: November 2020

As sociedades atuais lidam com um crescente manancial de informação fruto de diversas origens, divulgado por vários meios e construída com base em preocupações, interesses e olhares distintos. Com frequência utilizam-se as expressões “opinião”,” ponto de vista” e “perspetiva” sem se debaterem quais os significados e que ideias dão corpo a estas expressões/conceitos. Propõem-se este debate atendendo às conceções idealistas passando pelo Pós-modernismo e pelo “realismo crítico interno”. Partilha-se a perspetiva que a História é uma ciência que desenvolve o modo de compreender a realidade humana e considera-se necessário que este debate seja realizado com o objetivo de conscientemente se tomarem decisões válidas no percurso histórico. A narrativa histórica, face material da História, independentemente do suporte que utiliza, é natural e legitimamente multiperspetivada, considerando-se que é no criticismo mútuo que a validade pode emergir nas formas mais sofisticadas e se pode construir a compreensão histórica de forma interperspetivada. Este debate poderá contribuir para que os ruídos constantes que espelham interesses relativamente à(s) verdade(s) histórica(s) possam fazer emergir ideias e narrativas históricas mais sofisticadas construídas no diálogo múltiplo e plural.
Documentação linguística como parte das políticas de formação intercultural de docentes indígenas
Authors: Da Cruz Aline 
Published: November 2020

As tecnologias de descrição linguística e a formação docente, com vistas, respectivamente, à documentação, à conservação linguística e à educação escolar diferenciada, são importantes ações de fortalecimento das línguas e dos povos minorizados. Nessa linha de raciocínio, o presente texto objetiva discutir processos de formação docente na perspectiva intercultural, sustentados por ações que levem os estudantes a refletirem sobre a gramática de suas próprias línguas. Para tanto, o ponto de partida e o fundamento empírico da discussão são três experiências de formação de professores plurilíngues, realizadas pela pesquisadora durante seu próprio processo de formação como linguista, elaborando uma descrição gramatical de língua indígena e: 1) como monitora no magistério indígena de São Gabriel da Cachoeira-AM (SGC); 2) como professora no mesmo magistério; e 3) em curso voluntário na comunidade de Nova Vida-SGC. Essas experiências permitem repensar a suposta oposição entre formação docente e descrição gramatical, além de reconsiderar a complementaridade entre essas duas práticas.

Често су се у визуелном облику представљале разлике између модерног историјског искуства Јапана и Кине, посебно у вези са одговорима ових двеју земаља на западни империјализам у 19. веку. Научници јапанске и кинеске историје проблематизују претпоставке од 1960-их. Уствари, ове претпоставке су толико темељно критиковане да, бар када говоримо или пишемо другим научницима, можда се чини сувишним давати аргументе против њих. Ипак, оне упорно трају међу научницима. Овај рад ће, дакле, говорити широј публици о томе зашто су ове претпоставке проблематичне и о томе како можемо да предајемо о критичном тренутку историје источне Азије о коме говоре разноврсни пројекти - одговор на западни империјализам, превасходно Јапана, у деветнаестом веку.

Published: November 2020

The experiment was aimed at comparing the effect of preservation methods on proximate, vitamins and mineral composition of fresh, blanched and dried tomatoes. The tomatoes samples were divided into three; fresh, blanched and dried tomatoes.
The research was conducted at the Department of Biochemistry, Faculty of Basic Medical Science, Bayero University, Kano, between the month of February 2019 and August 2019. The Proximate Composition was determined using AOAC methods (1975), the Vitamins were determined by (Pearson Chemical methods, 1970), and Minerals using (Atomic Absorption Spectro-photometer).The results of this research revealed the Blanched tomatoes has significant higher (P=.05) percentage moisture (77.58±2.71), however it has the least percentage composition of Crude Protein and Carbohydrate. The fresh tomatoes has the higher composition of crude fibre (17.00±1.87) and crude protein (1.78± 0.13) as compared with the other two samples at (P=.05), while the dried sample has the higher percentage composition of crude fat and Carbohydrate, (8.34±0.84) and (21.77±2.02) at (P=.05) respectively. Vitamin A and lycopene content were found to be significantly higher (P=.05) in Dried tomatoes, with Vitamin C content of blanched tomatoes been significantly higher (P=.05). Mineral analysis indicates that sodium, magnesium, calcium, copper and lead has no significant difference in all the three samples.
Conclusion: This study reveals that dried tomatoes are also a good source of Vitamin A, lycopene and other nutrients.
Variational and Topological Methods for a Class of Nonlinear Equations which Involves a Duality Mapping
Authors: Cringanu Jenica 
Published: November 2020

The purpose of this paper is to show the existence results for the following abstract equation Jpu = Nfu,where Jp is the duality application on a real reflexive and smooth X Banach space, that corresponds to the gauge function φ(t) = tp-1, 1 < p < ∞. We assume that X is compactly imbedded in Lq(Ω), where Ω is a bounded domain in RN, N ≥ 2, 1 < q < p∗, p∗ is the Sobolev conjugate exponent.Nf : Lq(Ω) → Lq′(Ω), 1/q + 1/q′ = 1, is the Nemytskii operator that Caratheodory function generated by a f : Ω × R → R which satisfies some growth conditions. We use topological methods (via Leray-Schauder degree), critical points methods (the Mountain Pass theorem) and a direct variational method to prove the existence of the solutions for the equation Jpu = Nfu.

Published: November 2020

Aim: Intermittent fasting have been reported to have beneficial effect, in that it improves gut microbiota and lowers inflammation. This research is, however, targeted at evaluating the healing effects of fasting on ulcerative colitis in rats.
Study Design: A total of eighteen Wistar rats were used for this study, and were divided into three major groups; animals that were neither induced with colitis nor fasted (group 1), animals with colitis and were allowed to fast (group 2), animals with colitis but were not allowed to fast (group 3).
Place and duration of study: Department of Physiology, Ladoke Akintola University of Technology, Ogbomoso, Oyo State, between March, 2020 and July, 2020
Methodology: The weight of the 18 animals used was 180 ± 20 g. Colitis was induced by a single dose of intra-rectal administration of 1mL/100g body weight of 6% acetic acid. Animals in group 1 served as control animals. Animals in group 2 were only given access to food between 4:00 p.m and 6:30 p.m, whereas animals in group 3 were given food and water ad libitum. Animals were sacrificed ten days post colitis induction. Colonic levels of Tumor necrotic factor-alpha (TNFα), Glutathione (GSH) concentration, Superoxide dismutase (SOD), Catalase (CAT) and Myeloperoxidase (MPO) activities were measured. The blood glucose level in the animals was also recorded by the use of a glucometer.
Results: There was a reduction in the concentration of TNFα and GSH, an increase in CAT and SOD activities in the colitis animals that were allowed to fast when compared with colitis animals that were not allowed to fast, ten days post colitis induction. There was also the lowering of blood sugar level, all signifying the beneficial effect of fasting on chemically-induced colitis. Thus, intermittent fasting helped the animals to heal from chemically-induced colitis.

Published: November 2020

Aim: Test the effect of Azadirachta indica fruit extract on seed-borne fungi and seed performance of different rice varieties.
Study Design: Neem fruits harvested in the locality of Pala in Chad were used to assess the antifungal effect on rice seeds. Samples of eight rice varieties (TOX, CH3, CH8, WITA9 D6, D4, D3 and D1) were collected in Bongor, Chad to assess their performance against the aqueous extract of neem fruits.
Place and Duration of Study: This study was carried out at the Research Unit of Phytopathology and Agricultural Zoology of the Faculty of Agronomy and Agricultural Sciences of the University of Dschang/Cameroon from June to October 2018.
Methodology: Rice seeds were dipped in Azadirachta indica extract at concentrations of T25 (25 mg/ml), T50 (50 mg/ml) and T75 (75 mg/ml) for 1 hour before being incubated in petri dishes containing blotting paper. Distilled water (T0) and mancozeb 80 WP (TMn1 mg/ml) were used as negative and positive controls respectively.
Results: The results showed that the germination rate from rice seeds treated with Azadirachta indica extract was better (97.14%) than the rate from the negative controls (82.53%). The infection rate of rice seedlings, the number of rotten seeds and the number of abnormal seedlings were significantly (P =.05) lower for Azadirachta indica extract treatments than for the negative control (T0).
Conclusions: Neem (Azadirachta indica) fruit extract has a bio-fungicidal potential and a bio-stimulator of rice seed germination. This extract of Azadirachta indica fruit can be used to improve rice cultivation.

AbstractThe main drawbacks of today's state‐of‐the‐art lithium–air (Li–air) batteries are their low energy efficiency and limited cycle life due to the lack of earth‐abundant cathode catalysts that can drive both oxygen reduction and evolution reactions (ORR and OER) at high rates at thermodynamic potentials. Here, inexpensive trimolybdenum phosphide (Mo3P) nanoparticles with an exceptional activity—ORR and OER current densities of 7.21 and 6.85 mA cm−2 at 2.0 and 4.2 V versus Li/Li+, respectively—in an oxygen‐saturated non‐aqueous electrolyte are reported. The Tafel plots indicate remarkably low charge transfer resistance—Tafel slopes of 35 and 38 mV dec−1 for ORR and OER, respectively—resulting in the lowest ORR overpotential of 4.0 mV and OER overpotential of 5.1 mV reported to date. Using this catalyst, a Li–air battery cell with low discharge and charge overpotentials of 80 and 270 mV, respectively, and high energy efficiency of 90.2% in the first cycle is demonstrated. A long cycle life of 1200 is also achieved for this cell. Density functional theory calculations of ORR and OER on Mo3P (110) reveal that an oxide overlayer formed on the surface gives rise to the observed high ORR and OER electrocatalytic activity and small discharge/charge overpotentials.

AbstractSolar evaporation through a photothermal porous material provides a feasible and sustainable method for water remediation. Several photothermal materials have been developed to enhance solar evaporation efficiency. However, a critical limitation of current photothermal materials is their inability to separate water from the volatile organic compounds (VOCs) present in wastewater. Here, a microstructured ultrathin polymeric membrane that enables freshwater separation from VOC pollutants by solar evaporation with a VOC removal rate of 90%, is reported. The different solution‐diffusion behaviors of water and VOCs with polymeric membranes facilitate their separation. Moreover, owing to increased light absorption, enlarged liquid–air interface, and shortened mass transfer distance, the microstructured and ultrathin configuration of the membrane helps to balance the tradeoff between permeation selectivity and water production capacity. The membrane is not only effective for evaporation of simulated volatile pollutants in a prototype, but can also intercept complex volatile organic contaminants in natural water sources and produce water that meets drinking‐water standards. With practical demonstration and satisfactory purification performance, this work paves the way for practical application of solar evaporation for effective water remediation.
Cotton boll distribution: A review
Authors: Pabuayon Irish Lorraine B. , Kelly Brendan R. , Mitchell‐McCallister Donna , Coldren Cade L. , Ritchie Glen L. 
Published: November 2020

AbstractBoll distribution provides an important assessment of the response and adaptation of upland cotton (Gossypium hirsutum L.) to its environment and is strongly linked to yield and fiber quality and consequently to economic value. Several studies have measured boll distribution through end‐of‐season field or box mapping to study the spatiotemporal characteristics of bolls at both the plant and field levels, to quantify the effects of stress on cotton maturity and fiber quality, and to estimate yield as a function of the relative partitioning of resources to competing sinks. This paper discusses the environmental factors affecting boll production and distribution, reviews methods of measuring and analyzing boll distribution, and discusses the comparative advantages and drawbacks of these methods. With the advent of advanced imaging technologies, this paper also discusses the potential transition from traditional methods to machine‐based boll distribution measurements, the challenges associated with these technologies, and how continuous improvements in the baseline technologies being used in the different methods will translate to improved measurement capacities. Overall, major strides can still be made in the area of boll distribution measurement by combining the positive elements in the different studies described in this review to circumvent each of their respective limitations.

AbstractThe optimisation of the aqueous solubility of organic carbon monoxide releasing molecules based on a norborn‐2‐en‐7‐one scaffold is reported. This culminated in the synthesis of oCOm‐54 and oCOm‐56 which contain water solubilising polyethylene oxide groups. Both compounds are highly water soluble and release CO at pH 7.4 with half‐lives of 180 and 320 minutes respectively, to produce a reversible vasodilatory response in isolated, preconstricted tissue. Preliminary analysis indicates these oCOms are capable of forming micellar particles. Both oCOms exhibit significantly less cellular toxicity in AC16 human cardiomyocytes than earlier amine‐containing oCOms.
Polyethylene terephthalate waste‐derived activated carbon for adsorptive desulfurization of dibenzothiophene from model gasoline: Kinetics and isotherms evaluation
Authors: Fadhil Abdelrahman B. , Saeed Hajir N. , Saeed Liqaa I. 
Published: November 2020

AbstractThe present study concentrates on the preparation of activated carbon (AC) from a low‐cost precursor, namely, polyethylene terephthalate waste, as a potential alternative adsorbent to commercially activated carbon for desulfurization of model gasoline at ambient temperature. Polyethylene terephthalate was carbonized at 450°C, and the produced char was steam activated at 750°C for 90 min to prepare the AC. The morphology, crystallinity, and surface functional groups of as‐synthesized adsorbent were examined by scanning electron microscopy, X‐ray diffraction, and Fourier transform infrared spectroscopy, respectively. The so‐synthesized AC was employed in the adsorptive desulfurization of dibenzothiophene (DBT) from model gasoline. The effect of the initial concentration of DBT, AC dose, temperature, and contact time on the removal efficiency of DBT was investigated. The maximum desulfurization level (97.10%) was performed at 40°C using 0.30 g of the AC for 60 min. The Langmuir model best demonstrated the adsorption results with an adsorption capacity of 49.56 mg/g. The pseudo‐second‐order model best described the adsorption kinetics of DBT by the so‐synthesized AC. The obtained consequences exhibited that AC with high desulfurization capability could be synthesized from polyethylene terephthalate waste.
Effect of printing temperature on microstructure, thermal behavior and tensile properties of 3D printed nylon using fused deposition modeling
Authors: Guessasma Sofiane , Belhabib Sofiane , Nouri Hedi 
Published: November 2020

AbstractThe present investigation aims at the thermal conditions for the printability of nylon using fused deposition modeling (FDM). Dog‐bone like specimens are manufactured under two printing temperatures to measure the tensile performance of 3D printed nylon with respect to the feedstock material properties. Both Scanning Electron Microscopy (SEM) and X‐ray micro‐tomography analysis are conducted to shed more light on the microstructural arrangement of nylon filaments. Finite element computation based on microstructural implementation is considered to study the main deformation mechanisms associated with the nylon filament arrangement and the process‐induced porosity. The results show a narrow temperature range for printability of nylon, and a significant influence of the printing temperature on the thermal cycling, porosity content and mechanical performance. With the support of both numerical and experimental results, complex deformation mechanisms are revealed involving shearing related to the filament sequencing, compression at the junction points and tension within the raster and the frame. All these mechanisms are associated with the particular and regular arrangement of nylon filaments.
