Authors: M Thangam , K Ramachandrudu , J Ashok Kumar , S A Safeena , S Priya Devi
Published: October 2020

Vegetable cowpea or Yard long bean [Vigna unguiculata var. sesquipedalis L. (Walp)] is a warm season leguminous crops grown especially for vegetable purpose along the west coast of India. In Goa, pole type varieties are preferred over bushy types as they offer multiple harvests with comparatively longer pods. There is wide variability found for different morphological and other traits in the local types cultivated in the state of Goa. Exploration of genetic variability in the available germplasm is a prerequisite for initiation of any successful breeding programme. Twenty nine genotypes of vegetable cowpea including three improved varieties collected from different parts of Goa state were evaluated for twelve quantitative characters including yield. High variability was observed for pod yield/plant, number of pods/plant and pod length. The high variability for pod yield per plant is apparent as the pod yield ranged from 315.25 to 2070.45 g/plant with an average of 827.48 g per plant. Pod yield depends on number of pods per plant, pod length and pod weight. Number of pods per plant ranged from 36.65 to 147.80. Pod weight depends on pod length, number of seeds per pod and hundred seeds weight. Wide variation was observed for all these characters in the present study. The GCV value was maximum for pod yield per plant (g) followed by pod weight (g) and number of pods per plant. Low values of GCV were observed for days to first flowering, days to first harvest and number of seeds per pod. In the present study, the twenty nine genotypes could be grouped into fourteen clusters based on genetic distance. High coefficient of variation was observed for pod yield per plant, pod weight, number of pods per plant and pod length indicating their significant contribution in determining the inter cluster distances.

Published: October 2020

Hybrids and cultivars of single type tuberose was evaluated to fulfill the need to develop new hybrids as demanded by commercial growers. Evaluation of fifteen genotypes showed significant variation in growth, floral and bulb characters. Cultivar Arka Prajwal was significantly superior over all genotypes, which recorded least number of days for opening of 1st floret (78.55 days) with maximum diameter of spike (1.18 cm), length of floret (6.05 cm), weight of individual floret (3.12 g) and weight of spike (121.43 g).The hybrid genotype L1P4 (Variegated X Phule Rajani) was observed to be superior in terms of rachis length (39.78 cm), inter-nodal length (7.25 cm), length of bulb (8.09 cm), diameter of bulb (3.76 cm) and diameter of bulb-lets (1.85 cm). Among the hybrid genotypes L1P4 also recorded maximum plant height (116.39 cm), spike length (109.58 cm), weight of cut spike (105.08 g) and vase life (11.00 days). However, it was foundto be at par for number of florets per spike (57.25), length of floret (5.92 cm) and number of spikes per clump (10.14) with all other cultivars and hybrids tested. From the overall performance, it was found that the cultivar Arka Prajwal was the best. Genotype L1P4 found promising for loose as well as cut flower production because of its number of florets, inter-nodal length and spikes per clump which are important characters considering loose flower for taking maximum number of pickings. However, characters such as rachis length, spike length, vase life and weight of spike which are imperative for cut flowers are also noted superior in genotype L1P4.

Published: October 2020

Micronutrient imbalance in lime and sapota fruit crops result in unstable fruit yield, fruit shedding and degrade quality of the produce. A study was therefore conducted to evaluate micronutrient statusoflime and sapota orchard by analysing soil and plant samples. Soil samples were collected from surface (0-15cm) and sub-surface (15-30cm) depth representing whole orchard. At the same time, plant samples including 35-40 each for leaves and petiole samples each from lime and sapota field was also collected. Available micronutrients from soil samples were extracted using diethylenetriaminepenta acetic acid (DTPA) and it was in the order of manganese (Mn)> iron (Fe)> zinc (Zn)> copper (Cu) in both lime and sapota plantations. DTPA- extractable Zn and Cu showed low status, marginal status of Fe and sufficient level of Mn in soils of sapota plantations. In plant analysis, high concentration of Cu (869 mg kg-1) and Zn (411mg kg-1) was observed in lime leaves; however, in sapota crop Cu and Zn content was 8.25mg kg-1 and 16.7mg kg- 1 respectively. Similarly, Fe and Mn content of lime leaves was 197 and 43 mg kg-1 which was slightly higher than sapota leaves that recorded 128 and 49mg kg-1 of Fe and Zn respectively. In sapota plants, higher Mn and Cu concentration in leaf resulted in Zn deficiency symptoms such as shortened internodes or rosette disorders of sapota plants. Thus, correcting micronutrient deficiency is pre-requisite for qualitative and quantitative fruit production in tablelands of India.

Apresentação. O retorno a Aby Warburg no discurso historiográfico artístico contemporâneo
Authors: Pugliese Vera , Casazza Roberto
Published: October 2020

A presença de escritos referenciais de Aby Warburg é emblemática do crescente movimento de retorno a teóricos e historiadores da arte do início do século XX, pelo menos em dois diferentes âmbitos. Um deles se dedica a seus pressupostos teórico-metodológicos sob uma revisão epistemológica da história da arte, cuja especificidade nos coloca a pensar a possibilidade de acesso a uma região de saberes e não saberes sobre a diversidade cultural do Renascimento e de seu olhar sobre a Antiguidade, entendendo sua temporalidade como um fenômeno complexo. O outro âmbito é suscitado por questões oriundas da arte moderna e contemporânea, que impõem agenciar deslocamentos de sentido, conceitos operatórios e categorias de análise para considerar a produção visual (recente ou não) e problematizar constrangimentos classificatórios e modelos teóricos fundados por teorias que se pretendiam objetivas. A ordem epistemológica desse retorno, em ambos os âmbitos, parece questionar o próprio discurso historiográfico da arte em sua consideração da imagem e do tempo, pensados a partir de diálogos transdisciplinares abertos pela obra de Warburg (e de estudiosos warburguianos). Trata-se de considerar a abertura desse retorno face à consciência de uma inquietação, algo que poderíamos chamar de uma ausência fundamental: uma dúvida constituinte do próprio regime discursivo dessa disciplina quando ela assume a insistente perturbação que, de fundo, seria provocada pela região intervalar entre o objeto de investigação, a natureza de sua escolha e o próprio historiador da arte, que interdita narrativas totalizantes. O presente dossiê apresenta textos que refletem sobre a fertilidade e a potência política do pensamento warburguiano, no que concerne às lógicas de aproximação ou associação de imagens, de obras, de referências artísticas e culturais em curadorias de exposições, de coleções e acervos de arte já constituídos e em constituição, dos trânsitos e migrações de imagens de diferentes épocas e contextos em outras constelações, antes impensáveis, que doam às próprias imagens renovados sentidos em diferentes áreas.
The Epistemic Advantage of Self-Analysis for Cultural-Historical Insights
Authors: Weigel Sigrid
Published: October 2020

The article is devoted to analyze different versions and drafts of the 1923 Warburg’s Lecture, held in Kreuzlingen in 1923, on his travel to the United States in 1895/96, at the end of his long convalescence in the sanatorium of Ludwig Binswanger, as well as the respective lectures of 1897. This essay focuses on how the dispersion of these texts, their different dates and interferences in publications over decades had epistemological implications in the interpretation of his famous Conference. Thus, the contrast between fundamental points of these texts, both in their forms and contents – including deliberate terminological fluctuations –, raises theoretical questions that interfere with the understanding of Warburg’s work in its methodological specificity. It stands out his insertion in the style of characteristic thought identified as a movement of Kulturwissenschaft, the specificity of the relations of his work with Anthropology and Philology, but also with Psychoanalysis, especially in the process of certain Freudian formulations elaborated from a process of self-analysis.

FÉ E POLÍTICA EM MARTIM LUTERO
Authors: Gaede Neto Rodolfo , Stumpf João Henrique , Pagung Daniel
Published: October 2020

O artigo busca identificar interpretações e interações de Martim Lutero com a política institucional de seu tempo, a partir da análise de alguns de seus escritos, em especial seu comentário ao Magnificat de Maria e do escrito Da Autoridade Secular.  Na Idade Média, era inconcebível pensar Igreja e sociedade separadamente. Essa íntima relação entre o poder da Igreja e o poder político da época e a respectiva relação do reformador com os dois poderes o levou a refletir sobre a relação entre política e Igreja na sociedade. Tais reflexões estão contempladas em alguns de seus escritos. O presente artigo analisa de forma mais sistemática dois deles. Na interpretação do Magnificat, Lutero exortou as autoridades seculares a olharem para os pobres e marginalizados, buscando o bem comum ao invés de seus próprios interesses ou dos grupos já favorecidos economicamente.  No escrito Da Autoridade Secular, orienta as autoridades seculares a agirem cristãmente, identificando os limites e incumbências de sua ação na sociedade. Afirma que a autoridade secular não deve decidir sobre questões de fé,; tampouco, a Igreja deve almejar decidir sobre questões que competem ao poder político. As teses defendidas pelo reformador mostram-se extremamente atuais e proféticas diante da realidade política brasileira e do respectivo papel das igrejas nesse cenário.
Application of the gunsight technique to facilitate subintimal arterial flossing with antegrade-retrograde intervention for the treatment of lower extremity chronic total occlusion
Authors: Phadke Daniel Rohan , Sheeran Daniel , Angle John , Wilkins Luke
Published: October 2020

Objectives:

Endovascular treatment of atheromatous chronic total occlusions (CTOs) of the lower extremity using the subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) method may fail due to inability to position the antegrade and retrograde wires in the same plane. Failed attempted SAFARI in three limbs, in two patients, was rescued using a gunsight technique.

Material and Methods:

Retrospective procedure database review revealed three procedures where an occlusion could not be crossed despite antegrade and retrograde access which were treated using a novel technique for percutaneous puncture through antegrade and retrograde loop snares (gunsight technique).

Results:

Three limbs in two patients (mean age: 64 years) were treated using the gunsight technique. All three CTOs were successfully crossed and dilated with angioplasty and/or stents. A positive clinical outcome was achieved in each of the three affected limbs.

Conclusion:

The gunsight technique can improve technical success of SAFARI in the treatment of CTOs for atheroocclusive disease when there is failure to cross the lesion with standard endoluminal or subintimal approaches.

The development of digital technology makes it easy for humans to do activities, including compliance with the requirement of voice, data, and video communication in office buildings. Infrastructures are a primary consideration for a reliable connection, large-capacity, and stable communication lines. Recently, Fiber-optic communication systems are now the backbone of information signal delivery technology. This paper proposes a design of optical fiber transmission media for deployment in urban office buildings. It has been called fiber to the building (FTTB), which uses a fiber optic communication system to support the availability of multimedia network in an office area. A typical office building in an urban area has a multilevel structure that is used by various companies with multimedia network access services to support business activities. This study considers XGPON technology as a fiber optic-based broadband access technology that is deemed appropriate to the needs of the use of a multimedia network. The design begins with conducting a data collection survey. The next is the chosen device components based on the estimated distribution of the number of users. There are three parameters will be calculated include Power Link Budget (PLB), Rise Time Budget (RTB), and Bit Error Rate (BER), to determine the design feasibility. Based on PLB, RTB, and BER data, the proposed fiber to the building (FTTB) can meet the parameters to be achieved in the design, namely PLB of -27,24 dBm for downstream and -11,68 dBm for upstream, the value of is 0,049 ns, and value of BER is 0,186 x 10-1085. The design of FTTB can meet the requirement of users with a bandwidth of 9014,4 Mbps for 1200 users.

Temperature is one of the parameters other than radiation that can affect the performance of photovoltaic (PV) in relation to the output power and efficiency. This paper discusses the design of the PV cooling system using waters pray that controlled automatically. The temperature of the PV on the sensor as input to the controller and the output is the switch settings to turn on/off the pump in spraying water to the surface of the PV panel with the intention that the PV is always maintained at normal temperatures. The system was tested simultaneously on 4 PV panels @ 100Wp by involving PV without a cooling system with the same capacity during the day and the result was compared. Based on the results of PV temperature measurements in relation to the output power shows that PV with a cooling system generates higher output power than PV without a cooling system. By taking into account the involvement of power consumed by the cooling system consists of a controller and pump, the efficiency of PV rises slightly to 1.07 times.
Breaking Simple Scaling Relations Through Metal-Oxide Interactions: Understanding Room Temperature Activation of Methane on M-CeO2 (M= Pt, Ni or Co) Interfaces

The clean activation of methane at low temperatures remains an eminent challenge and a field of competitive research. In particular, on late transition metal surfaces such as Pt(111) or Ni(111), elevated temperatures are necessary to activate the hydrocarbon molecule, but a massive deposition of carbon makes the metal surface useless for catalytic activity. However, on very low-loaded M/CeO2 (M= Pt, Ni, or Co) surfaces, the dissociation of methane occurs at room temperature, which is unexpected considering simple linear scaling relationships. This intriguing phenomenon has been studied using a combination of experimental techniques (ambient-pressure X-ray photoelectron spectroscopy, time-resolved X-ray diffraction and X-ray absorption spectroscopy) and density functional theory-based calculations. The experimental and theoretical studies show that the size and morphology of the supported nanoparticles together with strong metal-support interactions are behind the deviations from the scaling relations. These findings point toward a possible strategy to circumvent scaling relations, producing active and stable catalysts which can be employed for methane activation and conversion.

Gallic acid (GA) inhibitory potential against oxidative stress and associated diseases, creates the importance for GA standardization in plant medicines. The present investigation was intended to quantify the amount of GA in Erythrina fusca leaves hydro-alcoholic extract (EFLHE) by the development of UV/Visible-spectrophotometric method and its validation. The study involved of EFLHE preparation via ethanolic maceration, followed by estimation of total phenolic content (TPC) or GA through the development of Folin-Ciocalteu reagent-based UV/Visible-spectrometric method and standard GA calibration curve. Developed method to estimate GA was validated using linearity, accuracy, precision, repeatability and ruggedness studies. The TPC analysis of EFLHE in concentration of 0.5, 1.0, 2.5, 3.0, 5.0, 10.0 µg/ml exhibited amount of GA as 98.0±8.71, 117.0±1.73, 217.1±3.45, 276.0±0.80, 289.1±1.11 and 295.2±1.19 GA equivalent (mg/g, dry weight) respectively. The linearity study revealed the range of GA from 0.5-10 µg/ml. The correlation coefficient for GA was found as 0.997 at 212 nm. Recovery analysis (accuracy) showed that little change in drug concentration could be accurately estimated. The precision study revealed low %RSD with the highest value of 0.43%, indicating substantial precision. The present study concludes that advanced method to estimate GA in EFLHE is rapid, simple, accurate, precise, and economic; and validated for linearity, accuracy, precision, repeatability and ruggedness. The study recommends that this method can be used for GA estimation in Erythrina fusca leaves extract.

Opioid use is associated with predictors of poor cardiorenal outcomes. However, little is known about the direct impact of opioids on podocytes and renal function, especially in the context of hypertension and CKD. We hypothesize that stimulation of opioid receptors (ORs) contributes to dysregulation of intracellular calcium ([Ca2+]i) homeostasis in podocytes, thus aggravating the development of renal damage in hypertensive conditions. Herein, freshly isolated glomeruli from Dahl salt-sensitive (SS) rats and human kidneys, as well as immortalized human podocytes, were used to elucidate the contribution of specific ORs to calcium influx. Stimulation of κ-ORs, but not μ-ORs or δ-ORs, evoked a [Ca2+]i transient in podocytes, potentially through the activation of TRPC6 channels. κ-OR agonist BRL52537 was used to assess the long-term effect in SS rats fed a high-salt diet. Hypertensive rats chronically treated with BRL52537 exhibited [Ca2+]i overload in podocytes, nephrinuria, albuminuria, changes in electrolyte balance, and augmented blood pressure. These data demonstrate that the κ-OR/TRPC6 signaling directly influences podocyte calcium handling, provoking the development of kidney injury in the opioid-treated hypertensive cohort.

Published: October 2020

Efficiency and quality of operation of local automatic control systems as part of an autonomous object is mainly determined by the regulator in their composition and the used control law, for the synthesis of which is necessary to use modern computer-aided design systems. The article presents the results of the application of genetic algorithm as a method of parametric synthesis of the PID-controller implemented in the SimInTech visual dynamic modeling environment, which currently is used by enterprises in the rocket and space sectors of Russian Federation. Object of research is the dynamic negative feedback system on the example of the automatic angular position of artificial satellite control system. The functional scheme and the simplified mathematical model of the system in the form of the transfer functions of its links are presented. The computer model of the system as well as a process of synthesis of the controller are implemented as a package of projects, based on standard blocks and submodels SimInTech.

Published: October 2020

The possibility of obtaining perspective geopolymer materials for use in the building industry was shown. Geopolymer materials are used with such advantages as high strength, density, water resistance, heat and heat resistance, environmental friendliness, durability, and high corrosion resistance. The raw material is rottenstone, a rock with a high silica content, which is widespread in Ukraine. Rottenstone is characterized by a ratio of SiО2:Al2O3 equal to 16… 20, which provides a high strength of the final material. It was indicated that physico-chemical processes that take place during polymerization are similar to those that take place in thin pellicles of the released SiO2 gel, cements the particles, and thus promotes hardening. As a result of the treatment of raw materials with alkali solution at temperatures of 80-120 °С, a monolithic solid material of olive color with a density of 1200-1700 kg/m3, humidity of 30-45% was formed. Precipitations were observed on the surface of the material due to the presence of non-chemically bound sodium and potassium cations in the pores of the geopolymer. When dried, they diffuse to the surface of the geopolymer and are subjected to atmospheric carbonization. It was indicated that in order to obtain a high-strength geopolymer material, it is necessary to carry out final heat treatment at temperatures close to 100 °С. The behavior of geopolymer samples aged over time at room temperature during their heating was investigated. The samples of the material are melted due to the presence of Na2O×SiО2×8Н2O and Na2O×SiО2×5Н2O crystal hydrates, which melt at relatively low temperatures at 48°С and 72°С, respectively. The formation of building geopolymer materials should take into account this melting by placing it in molds was concluded. Indicators of moisture loss at a temperature of about 100°С depending on the heat treatment time were obtained.

A cross-sectional study was conducted between November 2011 and March 2012 to determine the prevalence of mange mites and to identify the major mite species affecting small ruminants in Haramaya wereda (district), East Harerghe zone, Eastern Ethiopia. A total of 810 animals from both species (384 sheep and 421 goats) were sampled using the formula of [1]. The study showed that the prevalence of mange mite in sheep and goats was 3.34% and 5.94%, respectively. From 197 and 613, young and adult small ruminants examined for mange mites the recorded prevalence rate was 6.09% and 4.61%, respectively whereas among 373 and 437, male and female small ruminants examined for mange mites the prevalence rate of 4.02 and 5.26% was recorded, respectively. The prevalence rate recorded in lowland and midland was 4.22% and 2.77%, respectively. No statistically significant association was observed between the prevalence rate and different species, age and sex of the animals (p>0.05). However, there was statistically significant association between the prevalence rate of mange infestation and agro-ecological zones (p<0.05). The major species of mites identified were sarcoptes spp, psoroptes spp and demodex spp in goat and only psoroptes spp in sheep. From the mange mite species-affecting goats, sarcoptes scabies was the most prevalent species observed on 4.28% of the goats followed by psoroptes ovis (0.95%) and demodex caprae (0.71%). In sheep, the prevalence of the only identified species, psoroptes ovis was 3.34%. Further studies should be done to evaluate risk factors and the seasonal occurrence of mange in small ruminants in the area to devise effective control measure.

Authors: Enukwa Ettagbor Hans
Published: October 2020

This study was carried out to determine the effect of various watering regimes in different soils on seed germination and seedling establishment for two species (Dianthus Barbatus and Lespedeza cyrtobotrya) The ratio of water used for watering was 16ml water/100g soil. Three watering frequencies (i.e. once daily; once every 2 days; once every 3 days) were applied for two soil types (Leaf mold soil and merchantable soil) for a period of 150 days. The differences in seed germination, seedling survival and seedling growth were monitored in all experimental units. A more regular watering frequency increases soil moisture, and vice versa. The results showed that watering frequency had significant effects on seed germination (p=0.008), number of plant leaves (p=0.05), with visible but statistically insignificant effects on mean plant height (p=0.19) and seedling survival (p=0.3) for two plant species. The total height of plant species also varied greatly within treatments. Positive correlations were recorded between germination rate with leaf number (r=0.79, p=0.0001); plant height with survival rate (r=0.65, p=0.001); plant height with leaf number (r=0.77, p=0.0001); survival rate with leaf number (r=0.66, p=0.0001) etc. Seed germination and aboveground heights of D. barbatus and L. cyrtobotrya decreased at the more regular watering frequency of once daily in both soils. On leaf mold soil, the total height and mean height of L. cyrtobotrya decreased with increased water stress at once every 3 days watering frequency. Also, the total height of D. barbatus decreased with increased water stress at once every 3 days watering frequency on this soil, even though its mean height did not decrease. In contrast on merchantable soil, the total height and mean height of L. cyrtobotrya increased with increased water stress at once every 3 days watering frequency, indicating that this plant is more resistant to stress on this soil. Whereas, the total height and mean height of D. barbatus decreased with increased water stress on this soil. On leaf mold soil, once every 2 days watering was the most suitable watering frequency for both species in terms of achieving best seed germination and seedling establishment. In contrast on merchantable soil, once every 3 days watering frequency was most suitable for L. cyrtobotrya, whereas both once every 2 days and once every 3 days watering frequencies were suitable for D. barbatus on this soil. The results suggest that using the required watering frequency and soil type is imperative to ensure sustainability in plant production and seedling establishment.

Mathematical models have been widely used to understand complex phenomena. Generally, the model is in the form of system of differential equations. However, when the model becomes complex, analytical solutions are not easily found and hence a numerical approach has been used. A number of numerical schemes such as Euler, Runge-Kutta, and Finite Difference Scheme are generally used. There are also alternative numerical methods that can be used to solve system of differential equations such as the nonstandard finite difference scheme (NSFDS), the Adomian decomposition method (ADM), Variation iteration method (VIM), and the differential transformation method (DTM). In this paper, we apply the differential transformation method (DTM)  to solve system of differential equations. The DTM is semi-analytical numerical technique to solve the system of differential equations and provides an iterative procedure to obtain the power series of the solution in terms of initial value parameters.. In this paper, we present a mathematical model of HIV with antiviral treatment and construct a numerical scheme based on the differential transformation method (DTM) for solving the model. The results are compared to that of Runge-Kutta method. We find a good agreement of the DTM and the Runge-Kutta method for smaller time step but it fails in the large time step.
