Authors: Da’an S.A. , Jidangkat M. , Chaskda A.A. , Mwansat G.S.
Published: August 2020

This research surveyed some socio-economic activities of communities around Pandam Game Reserve (PGR) central Nigeria to determine their implications for biodiversity Conservation in PGR. Data were collected using structured questionnaires and field observations. Results showed a 100% response to questionnaires administered. Eighty three percent (83%) of the respondents were males while 17% were females. Eighty percent  (80%) attended at least primary school level of education while 20% had no form of formal education. Prominent among occupation of respondents was farming with 40% and the occupation of respondents with list response was hunting with 1%. Field observations showed the presence of the following human activities: logging, firewood collection, fishing, farm encroachment, cattle grazing and poaching. The implication of these socio-economic activities in PGR if left uncontrolled could result to biodiversity lost. A multi-stakeholder approach and participatory management of the  reserve which will consider the socio-economic concerns of locals have been suggested as a critical component for building cooperation. These if properly exploited is believed will contribute substantially to biodiversity sustainability in PGR.

Published: August 2020

Remediation of hydrocarbon polluted vadose zone (HPVZ) through percolation with solution of nutrient, nutrient-surfactant, or surfactant in glass columns was investigated in this study using standard methods. Percolated liquids from the columns and soils retrieved at the end of the  experiment were analyzed for nitrate, phosphate, sulphate, total-petroleum hydrocarbon, and selected microbial groups. Results obtained showed that there were nitrate, phosphate, and sulphate in the percolated liquids. Cumulative hydrocarbon in the percolated liquids was 5.35 – 7.59 % of cumulative hydrocarbon start-up concentration in the columns. Cumulative hydrocarbon attenuation across soil layers in column flooded with solution of nutrients (column NT), nutrient-surfactant (column NTS), and surfactant (column SF) were 89.29, 95.27, and 66.92 % respectively. There was more phosphate reduction in column NTS, and more sulphate reduction in column NT. Hydrocarbon-utilizing fungi in columns NT and NTSincreased from 3.5 Log10 CFU.g-1 to between 4.0 – 5.0 Log10 CFU.g-1, whereas a decrease was observed for column SF. Hydrocarbon-utilizing bacteria in all the columns increased from between 1.0 – 2.5 Log10 CFU.g-1 to between 2.0 - 3.5 Log10 CFU.g-1. Emergence of hydrocarbon utilization among anaerobic bacteria population was also observed in all the columns. It is concludedthat percolation with nutrient-surfactant  solution will be more effective in remediation of HPVZ, and that consequential migration of nutrients alongside hydrocarbons into groundwater canaid in enhancing biodegradation of the infiltrated hydrocarbons.

Published: August 2020

The aim of this study was to formulate non-effervescent floating drug delivery system of metronidazole tablets using Abelmoschus esculentus (Okra) (AE) gum as a binder and 2-camphanone (camphor®) as the sublimating agent. Granules were prepared by wet granulation technique using varying concentrations of AE gum (2, 4, 6 and 8% w/w) admixed with 1%w/w acrylate methacrylate copolymer. A 30 %w/w of 2-camphanone was used as the sublimating agent. The granules were characterized for micromeritic properties. And thereafter, compressed at a compression pressure of 25 N/m2 using a Manesty single punch tableting machine. The metronidazole tablet was then sintered at 70oC for 12 h. Drug-excipient compatibility study was done using Fourier Transform Infra-red Spectroscopy (FTIR). Tablets were evaluated for floating lag time, in-vitro buoyancy and release kinetics. FTIR studies showed that the excipients and the active pharmaceutical ingredient (API) i.e. metronidazole, were compatible. All the granules were free flowing, with Carr’s index ≤ 15 %, Hausner ratio ≤ 1.18 and angle of repose of ≤ 33.5o. The tablets had hardness and friability values of 5.0-9.5 N and 0.4-0.8% respectively. The floating lag time was 0 s showing that the tablets floated immediately after immersion in the simulated gastric fluid. The maximum % release (m∞) and time to achieve it (t∞) were ≥ 88 % and ≥ 10 h, respectively. Release exponent (n) for all the formulations had values >0.45, hence their release was by non-Fickian diffusion. Non-effervescent floating matrix tablets of metronidazole were formulated using AE gum as the binder and 2-camphanone as the sublimating agent. The formulated floating tablets had increased in-vitro retention time, which indicated potential for sustained release of the drug. If well developed, this may help reduce the oral dosing frequency and encourage patient adherence to the drug therapy.

Placement of Distributed Generation and Shunt Capacitor in Distribution Network using Cuckoo Search Algorithm
Authors: Uchendu Moses
Published: August 2020

This work aims at reduction in active and reactive power loss reduction in distribution networks as well as to improve the voltage stability of the networks. Optimum Distributed Generation (DG) placement and sizing is carried out in conjunction with shunt capacitor placement and sizing to determine the appropriate sizes of DG units and Capacitor banks to be placed in the networks so as not to violate certain constraints. The optimal sizes of the DG units and capacitor banks were obtained on application of a Cuckoo Search Optimization Algorithm while computations for Voltage stability was performed using the Voltage Stability Index (VSI). The obtained optimal sizes of DG units and Capacitors were individually and simultaneously placed on the distribution networks to ascertain the behaviour of the networks prior to and after their placements. The performance factors considered are power loss and voltage stability. A comparison of these performance factors under separate and simultaneous placement method was demonstrated using IEEE 33 and 69 test buses. Result show that power loss (active and reactive) reduced by 63.29% and 59.38% respectively for 33 bus system, with a 74.29% and 79.19% reduction on 69 bus system. Voltage stability also increased by 7.89% and 3.79% respectively for 33 and 69 bus system relative to values obtained for base case and separate DG and shunt capacitor placement.

Keywords: Distributed generation, shunt capacitor, Cuckoo Search Algorithm (CSA), power loss and voltage stability.

Published: August 2020

The increasing demand for roasted plantain has brought about recent interest to upgrade the local method of roasting to be more user-friendly, hygienic and versatile. The objective of this work was to design, fabricate and evaluate the performance of a low cost and affordable multi-heat source plantain roaster and to determine the effects of different heat sources (charcoal, gas and electricity) on the proximate and micronutrients composition of the roasted plantain. Heat supplied to each compartment and medium of transfer was determined. The roasted products from different heat sources were evaluated for moisture, crude protein, ash, crude fat, crude fibre and total carbohydrate contents of the samples. Potassium, magnesium and vitamin B6 were also determined. The proximate and micronutrient composition analyses were carried out. The results show that the average capacity and efficiency of the machine is 3.74 kg/h and 96.32% respectively. Moisture content of the fresh plantain is 58.27% while that of roasted plantain using gas, electricity and charcoal are 46.26%, 45.94% and 39.59% respectively. Ash content of fresh plantain is 5.89% while that of roasted plantain using gas, electricity and charcoal are 7.45%, 8.30% and 7.00% respectively. Crude fibre content of fresh plantain is 2.83% while that of roasted plantain using gas, electricity and charcoal are 3.27%, 3.41% and 3.43% respectively. Carbohydrate content of fresh plantain is 23.80% while that of roasted plantain using gas, electricity and charcoal are 33.41%, 32.35% and 43.02% respectively.

Elucidation of Sodium Hydroxide Catalyst and Solids Loading for Thermochemical Liquefaction of Tetraselmis sp. Microalga
Authors: Eboibi B.E.
Published: August 2020

The production of biocrude with and without sodium hydroxide catalyst (Na2CO3) through hydrothermal liquefaction of Tetraselmis sp. microalga at different organic solids loading was investigated. The HTL experimental study was conducted at reaction temperatures of 310oC, 330oC, 350oC and 370oC at 5 min fixed reaction time with organic solids loading of 10%w/w, 15%w/w, 20%w/w, 25%w/w, 30%w/w, and at 40%w/w. The results of the study showed that organic solids loading above 20%w/w had no substantial changes on biocrude yield. The catalyst had very little effect on the yield of biocrude but substantially enhanced its quality when compared with non-catalysed reactions. Although, Na2CO3 catalyst may be used for HTL of Tetraselmi sp. in laboratory-scale studies, it is highly unnecessary for commercial-scale. Thus potentially reducing the production cost in future commercialization of HTL-alga-biorefinery.

Authors: Odigie E.B. , Bolaji-Osagie S.O.
Published: August 2020

Pathological abnormalities observed in cells or tissues obtained from the uterine cervix of women are collectively referred to as cervical lesions. The condition is gradually becoming a menace as it can affect different category of women. It is more worrisome as religious women particularly are not spared from the deadly scourge. This study was to investigate cervical lesion and human papillomavirus in relatively healthy religious women attending Pentecostal churches in Benin City, Nigeria. A cross-sectional investigation of the participants using structured questionnaire and the liquid-based cytology from January to July 2017 was used as the data and sample collecting tools. Majority of religious women that participated in the survey (n=429) cut across 47 Pentecostal churches. The mean age of the respondents was 48.46years (±2SD) with the highest number of participants being age group (36-45years) 131/429(31%), and ≥66years 13/429(3%). HPV infection was 9/429(2.1%), and the worst hit was among age group (26-35years) 5/429(1.2%) followed by 3/429(0.7%) amongst age group 36-45years, and 1/429 (0.2%) from age group 46-55years. 51/429(11.89%) was cervical lesion positive, while cytopathology revealed inflammatory smears (acute and chronic cervicitis), atypical glandular cells (AGC), low-grade squamous cell intraepithelial lesions (LSIL), and atypical squamous cells of undetermined significance (ASCUS). Cervical lesion and subsequent HPV infections are prevalent within the study population. However, to avert the impending dangers (cervical cancer) posed by cervical lesions in the society, modesty in sexual exploitation and decent lifestyles are highly imperative.

Deconstructing Denominationalism in Igboland: A Liturgy of Bitterness
Authors: Nmah Patrick Enoch
Published: August 2020

This research work aimed at examining the effects of denominationalism in Igboland. The study revealed bitterness, antagonism, rivalry, moral barrenness, and spiritual bankruptcy that are dangers associated with denominationalism. Findings showed also the strengths and weaknesses of this narrow-minded party spirit in the area under review. The work recommended effective ecumenical-dialogue, exchange of programme, and inter-denominational communication as panacea to the challenges of party spirit. Methods of approach are historical and phenomenological methods coupled with the review of related extant materials. It concluded that shying away from engaging in inter-denominational relations through media for the purposes of Christian unity and evangelization amounts to playing the ostrich which has dire consequences. This paper assessed the challenges of worshipping God with bitterness among Igbo Christians. The problem is not planting Christianity in Igboland, but the method of evangelization which depends basically on denominationalism characterized by bitterness, envy, hatred, jealousy, wickedness and covetousness by which many Igbo Christians practice their faith. This in turn has adverse effect on the moral, social, intellectual and spiritual growth of the society. The bitterness is often within and without the denominations. The antagonistic attitude is seen among denominations such as Roman Catholic, Anglican, Methodist, Presbyterian, Seventh Day Adventist, Assemblies of God Church among others (Nmah, 2008).

Electoral Illiteracy and Democratic Citizenship in Zimbabwe
Authors: Zembere Monicah
Published: August 2020

This paper argues that electoral processes in Africa with special focus on Zimbabwe are never fair due to rampant electoral illiteracy. In this paper, illiteracy is far beyond the inability to read and write but encompasses a high degree of ignorance from not reading. The theory informing arguments in the paper is democratic citizenship. This is a qualitative research where data has been gathered through interviews and observation. Zimbabwe’s election processes of 2008, 2013 and 2018 had been used as case studies to substantiate the findings of this study. The major findings are that besides electoral illiteracy, factors such as intimidation, fear, manipulation (vote buying), partisan and hero worshipping also compromise the credibility of elections in Zimbabwe. The other finding is that as long as citizens are not familiar with electoral process of their country, the levels of participation of such people will remain low. In the light of these findings, this research recommends effective active citizenship if electoral crisis in Zimbabwe is to be addressed.

Music as Art and Science: An Evaluation
Authors: Ibekwe Eunice. U.
Published: August 2020

Music is presented in this discourse as a coin with two sides –thus as an Art also as a science. Looking at music as an Art draws one’s attention to the artistic features and characteristics of music such as styles and skills of performances as in dancing, singing, playing instrument and its position in other related areas with similar attributes. On the other hand, seeing music from the perspective of a science, the study of acoustics, sound productions, mathematical relationships and intervallic applications are evident. Art involves creative thinking and inspiration to achieve an expected goal or a set objective. Science on its own employs knowledge interaction and inquiries to produce new scientific discoveries. Music co-habits these two complex entities in a seemingly integrative association. This paper therefore is a critical examination and evaluation of musical potency that qualifies it as an art as well as science. The argument is anchored on qualitative evaluation of materials drawn from related literatures and sources. It finally draws the conclusion that since music fits in properly, and performs creditably as an art, as well as maintains great affinity with science, it should be treated as a bicameral discipline.

The Study of Primary and Internal Resonance on 3D Free-Free Double-Section Beam
Authors: Wang Yi-Ren , Chang Yun-Shuo
Published: August 2020

This work investigates the primary resonance and internal resonance of a double-section beam with cubic nonlinearities. This model can be applied in a wide range of engineering problems, such as rocket and missile structures. Even space technology has been developed for decades; several nonlinear properties deserve further study, especially, for the internal resonance. The method of multiple scales (a perturbation technique) is employed to analyze this nonlinear problem. This study focuses on finding the forcing conditions of this 3D double-section beam to trigger the often-ignored internal resonance or prime resonance in rocket structures. A primary resonance is found on a uniform free-free beam at certain flight speed. The three-to-one internal resonance of the double-section beam occurs within the first and the second modes in the diameter ratio of 1/0.75 with the length ratio of 0.33 or 0.51. The semi-analytical results are verified by the time marching numerical method.

When the Simplest Solution is not the Right one: A Case of a Blunt Occam’s Razor
Authors: Lewis Mark , Pouryahya Pourya
Published: August 2020

Abdominal pain in young females of childbearing age can be challenging when presenting to the Emergency department due to the atypical nature of presentation. Delays in diagnosis or misdiagnosis of appendicitis in this group can lead to higher rates of complications. Highlighting these cases will hopefully reduce the incidence of delayed and misdiagnosis and lead to better patient outcomes Here we present a case of a young female of childbearing age who presented with symptoms consistent with gastroenteritis, however ongoing abdominal pain prompted further investigation. The cause of the ongoing pain was confounded by the presence of an existing gynaecological condition and inconsistent presentation. A diagnosis of appendicitis was eventually made, and the patient proceeded to a laparoscopic appendectomy. On histopathological investigation the appendix was found to be gangrenous. The patient made a full recovery and was discharged from the hospital two days after surgery. Keywords:, Abdominal pain; Appendicitis; Emergency department; PID; pelvic pain; Occam’s Razor
Accuracy of Emergency Physicians in Diagnosis of Thoracic Aortic Dissection; a Retrospective Study Examining the Incidence and Outcome of Patients with TAD
Authors: Pouryahya Pourya , Meyer Alastair , Cheng Tan Jia
Published: August 2020

Objective: This study is a retrospective study looking at the incidence, management and outcome of patients with thoracic aortic dissection, and the accuracy of emergency physicians in diagnosing thoracic aortic dissection.

Background: Thoracic Aortic Dissection (TAD) is associated with a high mortality rate, more so if there is missed or late diagnosis (1-2% per hour). This makes the early diagnosis and prompt management a crucial component in mortality reduction.

Methods: A retrospective cross-sectional data analysis of adults presenting to three Monash Health Emergency Departments (ED) suspected for TAD, over a 1-year period from 1st July 2018 to 30th June 2019. Through the presentations, patients with confirmed TAD were identified and demographics, management options as well as outcome were analysed.

Results: 16045 adults presented to Monash health EDs with chest pain as their chief complaint over the study period. 68 had been investigated for TAD mainly with CT aortogram. 11 patients had a confirmed TAD (incidence rate of approximately 6.5 in 10000 patients per year), with majority (9 patients) being diagnosed with Stanford Type A dissection. Two patients died in the ED (mortality rate 18%) and others who survived were discharged home and stayed well in 3 months follow up.

Conclusion: Thoracic aortic dissection, in particular Type A, remains a condition with a relatively high mortality rate. To reduce this, high index of suspicion and prompt investigation is essential. We demonstrated good accuracy and competency of Emergency physicians in diagnosing and screening for thoracic aortic dissection.

Published: August 2020

The aim of this paper is to propose a methodology for managing the Li-ion battery lifetime of a whole fleet with the aim to improve the total cost of ownership of hybrid electric buses. This approach has been addressed from two points of view the bus-to-route and route-to-bus approaches. The bus-to-route optimization is focused on the energy management strategy generation of each bus of the fleet. A techno-economic, route energetic evaluation and battery aging analysis of the fleet have been performed. From the outcome of this analysis, the buses have been grouped, according the state of health of each bus. Based on the analysis and classification, the route-to-bus approach is applied. This technique lies on both, a re-evaluation of the energy management system and/or the re-organization of the buses according to the state of health of each bus. Increases of BT lifetimes up to 10.7% are obtained with the proposed approach.

Abstract. In this paper, we exploit the first 10-year data-record (2008–2017) of nitric acid (HNO3) total columns measured by the IASI-A/Metop infrared sounder, characterized by an exceptional daily sampling and a good vertical sensitivity in the mid-stratosphere (around 50 hPa), to monitor the causal relationship between the temperature decrease and the observed HNO3 loss that occurs each year in the Antarctic stratosphere during the polar night. Since the HNdepletion results from the formation of polar stratospheric clouds (PSCs) which trigger the development of the ozone (O3) hole, its continuous monitoring is of high importance. We verify here, from the 10-year time evolution of the pair HNO3-temperature (taken from reanalysis at 50 hPa), the recurrence of specific regimes in the cycle of IASI HNO3 and identify, for each year, the day and the 50 hPa-temperature (drop temperature) corresponding to the onset of denitrification in Antarctic winter. Although the measured HNO3 total column does not allow differentiating the uptake of HNO3 by different types of PSC particles along the vertical profile, an average drop temperature of ∼ 191 ± 3 K, consistent with the nitric acid trihydrate (NAT) formation temperature (close to 195 K at 50 hPa), is found. The spatial distribution and inter-annual variability of the drop temperature are briefly investigated and discussed in the context of previous PSCs studies. This paper highlights the capability of the IASI sounder to monitor the long-term evolution of the polar stratospheric composition and processes involved in the depletion of stratospheric O3.
Reclaiming the memory of pioneer female geologists 1800–1929
Authors: Vincent Aude
Published: August 2020

Abstract. Female earth scientists existed in the 19th century and the beginning of the 20th century in a number exceeding what we generally imagine. In this paper I present information on 210 of them who were active from 1800 to 1929. These women often overcame great challenges to achieve their positions, sometimes only to have their work attributed to men they worked with or for. Gender discrimination made access to university difficult and access to scientific careers even harder. They found several ways to overcome these difficulties thanks to the support of their parents or to the more ambiguous support of husbands or academic male mentors, through staying single, and through teamwork and mentorship with other women. In the same way many past female artists have been recently rediscovered, women scientists are progressively being saved from the dustbin of history, a huge task that has already been undertaken by several researchers. In addition to the review of their research, a fresh contribution to this collective work in progress is made with the presentation of hydrogeologist Norah Dowell Stearns. Finally, some reflections and suggestions are included on how we could fight this oblivion to which their work, their personalities and modern research on them are subject to.
Modelling the potable water quality in a distribution network based on the hydraulic conditions
Authors: Tomperi Jani
Published: August 2020

Abstract. Abnormalities in hydraulic conditions inside a water distribution network are strongly related to the deterioration of potable water quality. Leaking pipes and valves, for instance, cause changes in water hydraulic conditions and may allow the entry of microbes to the distribution system. Flow and pressure shocks can detach soft deposits and biofilms from the pipe surface which is shown among others as the elevated concentrations of bacteria, metals and turbidity in water. On that account, monitoring the hydraulic conditions in a distribution network and utilizing this information in developing a predictive water quality model assists providing a sufficient amount of potable water with an appropriate quality for the consumers use. In this paper, the water quality at the end part of the district metered area is modelled based on only the water flow and pressure measurements along the distribution network. The developed model can be utilized in proactive operation as it is able to show the potable water quality hours in advance before it is discovered at the end part of the distribution network.
The Fractional Energy Balance Equation for Climate projections through 2100
Authors: Procyk Roman , Lovejoy Shaun , Hébert Raphael
Published: August 2020

Abstract. We produce climate projections through the 21st century using the fractional energy balance equation (FEBE) which is a generalization of the standard EBE. The FEBE can be derived either from Budyko–Sellers models or phenomenologically by applying the scaling symmetry to energy storage processes. It is easily implemented by changing the integer order of the storage (derivative) term in the EBE to a fractional value near 1/2. The FEBE has two shape parameters: a scaling exponent H and relaxation time τ; its amplitude parameter is the equilibrium climate sensitivity (ECS). Two additional parameters were needed for the forcing: an aerosol re-calibration factor α to account for the large aerosol uncertainty, and a volcanic intermittency correction exponent ν. A Bayesian framework based on historical temperatures and natural and anthropogenic forcing series was used for parameter estimation. Significantly, the error model was not ad hoc, but was predicted by the model itself: the internal variability response to white noise internal forcing. The 90 % Confidence Interval (CI) of the shape parameters were H = [0.33, 0.44] (median = 0.38), τ = [2.4, 7.0] (median = 4.7) years compared to the usual EBE H = 1, and literature values τ typically in the range 2–8 years. We found that aerosols were too strong by an average factor α = [0.2, 1.0] (median = 0.6) and the volcanic intermittency correction exponent was ν = [0.15, 0.41] (median = 0.28) compared to standard values α = ν = 1. The overpowered aerosols support a revision of the global modern (2005) aerosol forcing 90 % CI to a narrower range [−1.0, −0.2] W m−2 compared with the IPCC AR5 range [1.5, 4.5] K (median = 3.2 K). Similarly, we found the transient climate sensitivity (TCR) = [1.2, 1.8] K (median = 1.5 K) compared to the AR5 range TCR = [1.0, 2.5] K (median = 1.8 K). As commonly seen in other observational-based studies, the FEBE values are therefore somewhat lower but still consistent with those in IPCC AR5. Using these parameters we made projections to 2100 using both the Representative Carbon Pathways (RCP) and Shared Socioeconomic Pathways (SSP) scenarios and shown alongside the CMIP5/6 MME. The FEBE hindprojections (1880–2019) closely follow observations (notably during the hiatus, 1998–2015). Overall the FEBE were 10–15 % lower but due to their smaller uncertainties, their 90 % CIs lie completely within the GCM 90 % CIs. The FEBE thus complements and supports the GCMs.
On the increased climate sensitivity in the EC-Earth model from CMIP5 to CMIP6

Published: August 2020

Abstract. Many modelling groups that contribute to CMIP6 (Coupled
Model Intercomparison Project Phase 6) have found a larger equilibrium
climate sensitivity (ECS) with their latest model versions compared with the
values obtained with the earlier versions used in CMIP5. This is also the case for
the EC-Earth model. Therefore, in this study, we investigate what developments since
the CMIP5 era could have caused the increase in the ECS in this model. Apart
from increases in the horizontal and vertical resolution, the EC-Earth model has also substantially changed the representation of aerosols; in
particular, it has introduced a more sophisticated description of aerosol
indirect effects. After testing the model with some of the recent updates
switched off, we find that the ECS increase can be attributed to the more
advanced treatment of aerosols, with the largest contribution coming from
the effect of aerosols on cloud microphysics (cloud lifetime or second
indirect effect). The increase in climate sensitivity is unrelated to model
tuning, as all experiments were performed with the same tuning
parameters and only the representation of the aerosol effects was
changed. These results cannot be generalised to other models, as their CMIP5
and CMIP6 versions may differ with respect to aspects other than the aerosol–cloud
interaction, but the results highlight the strong sensitivity of ECS to the
details of the aerosol forcing.

Rubber (Hevea brasiliensis Muell. Arg., Euphorbiaceae) is a tropical tree crop mainly grown for the industrial production of latex. The rubber sector in Cameroon is faced with the effects of global economic crisis and a drop in the yield of latex due to several pests and diseases. This study focused on leaf diseases caused by Fusarium oxysporum and Pestalotiopsis microspora. The fungi were isolated from the leaves of the rubber plant and cultured for characterization on two media (Potato Dextrose Agar (PDA) and Potato Carrot Dextrose Agar (PCDA)) at various temperature and pH levels. Using the poison food technique, an in vitro assay was done to assess the effect of two fungicides (Synthetic Fungicide 1 (SF1) and Synthetic Fungicide 2 (SF2)) at the respective doses of 0.006, 0.013 and 0.025 g.L-1, and 0.005, 0.01 and 0.02 g.L-1 on the growth of the two fungi. Results obtained show that PDA is most favourable for the growth of both fungi compared to PCDA. Both fungi attained optimal growth at pH 7 and at an incubation temperature of 25 oC. Neither F. oxysporum nor P. microspora grew on SF1-amended PDA and PCDA at all doses of the fungicide. SF2 significantly (P>0.05) inhibited the growth of P. microspora by 53.3% at the dose of 0.025 g.L-1 while F. oxysporum was less sensitive to the fungicide at all doses. In vitro pathogenicity test revealed similar disease symptoms as those observed in the field. This study shows that SF1 is the best fungicide against F. oxysporum and P. microspora as it gave 100% inhibition on the growth of both fungi.

Authors: Klosinski Daniele Vanessa , Loss Adriana Salete
Published: August 2020

O presente artigo objetiva problematizar a condição subjetiva da criança enquanto sujeito num contexto fortemente influenciado pelos pressupostos neoliberais. Desse modo, o estudo qualitativo e de abordagem exploratório-interpretativa buscou refletir sobre a necessária construção conceptual da criança como sujeito histórico e de interação, no sentido de superar as influências paradigmáticas neoliberais da Educação Infantil. Desse modo, a metodologia de estudo englobou a pesquisa bibliográfica, alicerçada em autores como: Ariès (1981); Sarmento (2005); Dewey (1979); Teixeira (1934); Dardot e Laval (2016); Larrosa (2015). A pesquisa constituiu-se da contraposição do paradigma neoliberal de infância pela concepção da subjetivação infantil, tendo em vista as interações, as experiências e o brincar. Por fim, as reflexões chamam atenção para o fato de os espaços educacionais romperem com a dogmatização pedagógica neoliberal, de modo a firmar-se na concepção da criança com direitos de aprendizagem por meio do brincar.
DOS CONCEPCIONES DE LA INTERPRETACIÓN JURÍDICA
Authors: Moreso José Juan
Published: August 2020

En este breve texto el autor nos introduce a la polémica entre Ricardo Guastini y Rafael Hernández Marín en torno a la interpretación del derecho. En dicha polémica Guastini defiende el escepticismo, mientras que Hernández Marín defiende el cognoscitivismo. Estas maneras diferentes de entender la interpretación jurídica son puestas a prueba en un interesante intercambio de ideas que nos permite apreciar los alcances y límites de cada posición.
