Field experiment was conducted at Agricultural College and Research Institute, Coimbatore during summer, 2007 to study the effect of drip fertigation levels and frequencies on nutrient uptake rate and relationship with grain yields of hybrid maize. Four fertigation frequencies (once in 6, 9,12 and 15 days), two fertilizer levels (100 and 150 percent of RDF), surface irrigation with 100 per cent RDF and absolute control (no fertilizer) were included as treatments in this study. Supply of 150 per cent of RDF once in 6 days (T 5 ) recorded significantly higher nutrient uptake than 100 per cent of RDF. Absolute control (T10 ) recorded the lowest plant nutrient uptake rate followed by surface irrigation with 100 per cent RDF (T9) for NPK throughout the cropping period. The results revealed that application of nutrients through fertigation very frequently (once in six days) with 150 per cent RDF (T 5 ) recorded higher uptake rate for all nutrients. The uptake rate of nutrients during 30-60 DAS was twice higher than the initial stage (0-30 DAS) for Nitrogen (N) and Potassium (K). With respect to Phosphorus, it was higher during 30-60 DAS and the increment was slightly higher than initial stage unlike N and K. Correlation Analysis indicated that N and K were highly correlated with grain yield than P.

A field experiment was conducted to study the effect of Vrkshayurvedic farming on yield attributes of maize at central farm of Agricultural College and Research Institute, TNAU, Madurai from September 2009 to January 2010. The experiment consisted of 20 treatments: five different green leaf manures (Albizia lebbek, Gliricidia sepium, Leucaena leucocephala, Delonix regia, Peltophorum ferrugineum) @ 5 t ha -1 as basal nutrition in main plot and four different tree leaf extracts (Alangium salvifolium, Aegle marmelos, Morinda tinctoria, Annona squamosa) @ 5 % in the form of five foliar sprays at 25, 39, 53, 67 and 82 DAS in sub plot. The results indicated that there were significant differences in yield attributes of maize due to the incorporation of green leaf manures and foliar spraying of tree leaf extracts. All the yield parameters were found to be high in the plot that received Albizia lebbek as green leaf manure with foliar spraying of Annona squamosa. The highest yield of 1820 kg ha -1 was recorded in the plot that received Albizia lebbek as green leaf manure and foliar sprays of Annona squamosa, which was six times higher than the zero input management and almost 50 per cent of the yield realized from high input management (CPG management). The economic analysis showed that higher net return of Rs. 20367 ha -1 and benefit cost ratio 1:2.26 were recorded by the treatment combination of Albizia lebbek and Annona squamosa.

A critique of the traditional and the post-gettier theories of justification: an intervention with epistemological functionalism
Authors: Anthony Raphael Etuk
Published: May 2023

In their quest to refute the sceptics’ challenge to the possibility of knowledge, epistemologists have over the years strived to demonstrate how our beliefs can be appropriately justified. This paper critically examines two of these traditional or anti-sceptical theories of justification, namely: Foundationalism and Coherentism, as well as three famous post-Gettier theories of justification: Reliability, Defeasibility and Causal theories. Notwithstanding their relevant contributions in clarifying the conditions for the justification of knowledge, the paper argues that none of these theories attains the requirements of rational success without vulnerability to the sceptics’ challenge, since each is nettled with some identified epistemic defects, especially due to their emphasis on a single and fixed idea of rational justification – with preference for formal adequacy over functional efficacy of knowledge claim in human inquiry. As a way forward, the paper argues for epistemic justification in a functionalistic framework and concludes with the positive recommendation of this perspective as a more viable alternative approach to epistemic justification. The expository and critical methods of philosophical analysis are adopted in the work.

Nibung and Bayas plants are members of the Arecaceae family, which is characterized by monocots, solitary or clumped stems, pinnate compound leaves, and flower frames. The province of Riau contains Nibung (O. tigillarium). Nibung (Oncosperma tigillarium) and Bayas (Oncosperma horridum) are members of the same family, but their morphology and habitat are distinct. This study seeks to determine the morphological distinctions between Nibung and Bayas plants found in the province of Riau, as well as their distribution. This investigation utilized field samples collected from two locations: Rantau Bertuah Village and Tanjung Medang Village. Additional analysis of morphological characters, notably diagnostic characters, and distribution data obtained from the GBIF website using secondary data. The results revealed morphological distinctions between O. tigillarium and O. horridum, particularly in terms of habitat, leaf arrangement, stem texture, and thorn texture. In contrast to the leaves of O. horridum, O. tigillarium leaves are arranged (facing) in the opposite direction. The stem of O. tigillarium is silky, whereas that of O. horridum is fibrous and textured. The thorns of O. tigillarium have a smooth and thin texture, whereas those of O. horridum are rough and dense. In addition, Nibung and Bayas plants have strikingly different distributions. O. tigillarium grows in marshy zones along the coast, whereas O. horridum grows on mountain slopes and plateaus.

Bioactive compounds isolated from leaves of Acioa barteri are responsible for its antiinflammatory activity. The result of qualitative and quantitative phytochemical analysis confirmed the presence flavonoids, alkaloids, Tannins, Resin, Saponins, Cardiac glycosides, Terpenoids, Steroids and Phenols. The result of anti-inflammatory activity testing showed that the plant extract possessed anti-inflammatory activity which was found to be dose dependent. At the doses of 250 mg/kg, 500 mg/kg, and 1000 mg/kg the percentage inhibition after 24 hours of administration was found to be 19.6%, 29.64%, and 49.75% respectively. The percentages 29.64% and 49.75% were found to be higher than 27.64% produced by the standard drug (Diclofenac) at 15 mg/kg. A good number of active compounds were isolated and identified by GC-MS, which include, Trilinolein, Pregn-4-ene 3, 20-dione, 17 epoxy, Octadecanoic acid 2-(hexadecyloxy) ethyl ester, Limonin, Colchicine, Paromomycin and Oleic acid eicosyl ester. Pregn-4-ene, 20-dione, 17 epoxy, Limonin, Colchicine and Octadecanoic acid 2-(hexadecyloxy) ethyl ester have been reported to possess antinflammatory activities. The result of the percentage inhibition on the Carrageenan induced paw edema albino rats obtained showed that the leaves extract of the plant possessed anti-inflammatory activity and this justified the use of this plant in ethnomedicine.

Oldest old are the fastest growing age group in most countries of the world, including the Russian Federation. Disability and institutionalization in oldest old is associated with an increased risk of cognitive impairment. The relationship between cognitive status and other geriatric syndromes has not been studied sufficiently in institutionalized oldest old.

Objective. To assess the relationship between cognitive status and geriatric syndromes in persons ≥ 90 years, who live in long term care facilities (LTCF).

Material and methods. The study involved patients aged ≥ 90 years, who were examined in the LTCF of Moscow. All patients underwent a neuropsychological examination, which included Mini-mental State Examination (MMSE), Frontal Assessment Battery (FAB), 5-word test, clock-drawing test and verbal fluency. A comprehensive geriatric assessment was carried out for all the subjects. To diagnose the frailty, we used the Short Physical Performance Battery (SPPB). The Bartel index was used to assess performance of activities of daily living. Instrumental activities of daily living were assessed using the Lawton scale. Nutritional status was assessed based on the Mini-Nutritional Assessment. The pain intensity syndrome was assessed by visual analogue scale. To detect dinopenia we used dynamometry with manual dynamometer. Statistical data analysis was performed using the statistical program SPSS 23.0 (SPSS Inc., USA). Fischer’s two-sided accurate test was used for two groups comparison. The relationships between the variables were evaluated using binary logistic regression with calculation of the odds ratio (OR) and 95% confidence interval (CI).

Results. Dementia was diagnosed in 69% of patients. According to multivariate analysis, sensory defi ciency (OR 4.23; CI 95% 1.96–9.09; p < 0.001), malnutrition (OR 2.68; CI 95% 1.10–6.52; p = 0.030), fecal incontinence (OR 4.37; CI 95% 2.14–8.90; p < 0.001), frailty (OR 4.23; CI 95%; 1.96–9.09; p < 0.001) are associated with the presence of dementia; an increase in age for every 1 year correlates with an increase in the chances of having dementia by 15%. Urinary incontinence and chronic pain syndrome were noted in more than half of oldest old, constipation syndrome and falls syndrome were detected in more than a third of the subjects, and more than 2/3 of oldest old had dinopenia.

Conclusion. The majority of institutionalized oldest old suffer from dementia, while an increase in the chances of having it is associated with frailty, sensory deficiency, malnutrition and an increase in the age of oldest old.

Published: May 2023

Forest fires are representative natural disasters resulting from dramatic global climate change in these modern times. When forest formation is insufficient due to forest damage caused by fire, secondary damages such as landslides occur during the winter thawing period and heavy rains. In most countries, only a limited area is managed as CCTV-centered monitoring systems for forest management. For the landslide prediction, markers containing 3D spatial coordinates were located on the slopes of the danger areas in advance. Then 3D mapping and angle of repose were obtained by periodic drone imaging. The recognition range and angle of view of markers were defined, and a new method for predicting signs of landslides in advance was presented in this study.

As a result of research analysis using online survey and in-depth interview research method, it was found that both intrinsic and extrinsic motives have a complex effect on artists and teachers' motivation to participate in the project. As for the effectiveness of participating in the project, the trust between artists and teachers and the contribution of education were positive, but the trust and satisfaction with the institution were negative. In order to increase the effectiveness of the project, it is required to improve the operation and management of the operating institution. Motivation and effectiveness of project participation are important factors in improving the quality of a project, and it is hoped that this study will serve as a basis for practical discussions on the role of operating institutions and projects.
Traumatic Coronary Artery Dissection as A Potential Cause of Acute Myocardial Infraction in Motorcycle Accident
Authors: Tondas Alexander Edo , Tandri Fredy , Zulkarnain Edrian
Published: May 2023

Background: Chest pain in blunt chest trauma can be caused by various intrathoracic injuries. Pneumothorax, hemothorax, and rib fractures are commonly seen in the emergency department. Although cardiac involvement is very rare, the probability should not be excluded.

Case Illustration: A-31-years-old male who complained of chest pain and diaphoresis was brought to the emergency department after a high-speed motorcycle collision. Chest X-ray revealed no abnormality but a 12-lead Electrocardiogram (ECG) demonstrated ST-segment elevation in lead I, AvL, V2-6, and atrial fibrillation. Because of the unusual presentation, the decision was to proceed with percutaneous coronary intervention (PCI). Coronary Angiography detected a thrombus at proximal LAD and spiral dissection at mid LAD (TIMI 2 Flow). After the procedure, he was transferred to the High Care Unit.

Conclusion: Following blunt chest trauma, chest pain in the setting of a vehicle collision can be caused by dissection of the coronary artery. Prompt cardiac workup (ECG, cardiac enzyme, and echocardiography) must be done in a highly suspected patient.

Authors: Almazini Prima , Soesanto Amiliana M , Kuncoro Ario S , Ariani Rina , Rudiktyo Estu , Sukmawan Renan
Published: May 2023

Background:

Survived from COVID-19 infection, some patients yet have residual symptoms. Multi-organ and mechanisms of disease can be involved. The data regarding echocardiographic dimension and function of the cardiac in the COVID-19 survivors remains scarce.

Method:

This was a descriptive cross-sectional study that involves a total of 63 subjects. Subjects were employees and medical residents at National Cardiovascular Center Harapan Kita, who previously get infected by COVID-19. Each subject was examined transthoracic echocardiography once at the time of recruitment. Echocardiographic parameters obtained in this study included dimension and systolic function of the left ventricle and right ventricle, global longitudinal strain by 2D speckle tracking echocardiography, and myocardial work index.

Result:

More than a half of the subjects experienced persistent symptoms after recovery from COVID-19 infection and mainly was fatigue (33.3%). The timing of data acquisition on the median was 32 days after the negative of the COVID-19 test result. 2D echocardiography measurement of left ventricle indicated mean of end-diastolic diameter and end-systolic diameter was 45 mm and 27 mm, respectively. The mean ejection fraction (EF) of the left ventricle by Simpson’s biplane method was 61%. The median of tricuspid annular plane systolic excursion (TAPSE) parameter was 23 mm and the fractional area change (FAC) parameter was 39%. The mean of global longitudinal strain (GLS) was -19.6%.

 

Conclusion:

After recovery from COVID-19 infection, some survivors may have post-acute infectious consequences of COVID-19 such as fatigue, dyspnea, and malaise. However, echocardiographic findings in those patients with mild symptoms, including 2D echocardiography, myocardial strain analysis, and myocardial work index, indicate normal dimension and systolic function in both left ventricle and right ventricle.
Photocatalytic Degradation of Methyl blue by TiO2 Nanoparticles Incorporated in Cement
Authors: Alshabander Ban , Mays Bassim Abd-Alkader
Published: May 2023

In this study, titanium dioxide (TiO2) nanoparticles incorporated with cement were synthesized by a simple casting method as a function of the concentration of TiO2 (0.2, 0.4, 0.8, 1, and 2 wt%). The prepared samples were characterized using the techniques of Field Emission Scanning Electron Microscope (FESEM) and UV-Visible spectrophotometer, which were used to measure the adsorption spectra. The observed photocatalytic efficiency of TiO2 nanoparticles (NP) incorporated with cement was investigated by decomposing the dye methyl blue (MB) solution under sunlight irradiation. According to the slope, the value of the k constant at the best sample is 0.8 wt%, k = 0.8265 min-1. FESEM images of the TiO2/cement with 0.8 wt% content show the TiO2 NPs were well-attached to cement particles, and they covered the cement surface. The increase in photocatalytic (PC) activity was due to an increase in TiO2 concentration in the cement, which best occurs at 0.8 wt% of TiO2 in cement. The degradation at the MB (5 ppm) was 98.864 % after 120 min of sunlight irradiation. The method involves easily and simply preparing TiO2/cement that is used in self-cleaning and studying the effect of different festive factors, including the concentration of the dye. The preparation of TiO2/cement was successful as a photocatalyst for a self-cleaning surface.

This study investigates the thermal performance of a solar evacuated tube collector (SETC) using nanoparticles suspended liquid (NSL) as the heat transfer fluid (HTF). The NSL is composed of water with different concentration of TiO2, CuO, Cr2O3, TiO2+CuO+ Cr2O3NSL withaverage size of ~25 nm. The experimental results show that the use of NSL increase the thermal performance of the SETC to be about 2% higher than that of the SETC without NSL. The enhancement in the thermal performance is mainly attributed to the higher thermal conductivity and specific heat capacity of the NSL. In addition, the effects of NSL concentration, flow rate and temperature on the thermal performance of the SETC with NSL were also studied. It was observed that the thermal performance of the SETC with NSL increases with increasing NSL concentration and flow rate but decreases with rise in the temperature. The results of this study can be used to optimize the design of solar evacuated tube collectors using NSL as the HTF for better thermal performance.
Philosophy in the Age of Post-Truth: Servant of the King or Clown in the Agora
Authors:   Skovoroda Institute of Philosophy, National Academy of Aciences of Ukraine, Volkovskyi Volodymyr
Published: May 2023

This article touches on two main themes of popular debate in the community of philosophers and the international information space. On the one hand, it deals with the emergence of the age of “Post-truth,” and related value, worldview and sociopolitical transformations. On the other hand, the article looks into the crisis of philosophy as a scholarly field and discipline, as well as debates around the prospects of philosophy’s survival in the current age, whatever it may be called (Post-industrial, Information, Post-truth, etc.). The main thesis lies in the fact that it is precisely in the age of Post-Truth that philosophy gains enormous relevance; however this new sociocultural situation demands that philosophy regain certainty of its role and position in society. Two typical roles and positions, two forms of philosophers’ communications with society thus emerge. Aphoristically they may be expressed as the Servant of the King (thus, a servile attitude to power, whether secular or ecclesiastical) or the Clown in the Agora (or the market of educational and intellectual services, governed by “market laws,” familiar to Sophists of the Ancient world). The author presumes that our age is in many fundamental respects similar to the age of the Sophists, especially in how higher education becomes reoriented towards market demand and mass preferences. The author describes the dialectics of freedom of philosophical thinking between outside compulsion and the needs of funding, and shows that the problem is far from being resolved.
Modernity and Peace. The Lessons of Kant’s Applied Enlightenment
Authors:   Ukraine at the Kennan Institute, Woodrow Wilson International Center for Scholars, Minakov Mykhailo
Published: May 2023

The article contains an analysis of the major lessons of Immanuel Kant’s philosophical project of perpetual peace in the context of development of contemporary political systems and international order. The author reviews the history of philosophical and legal accounts of perpetual peace, as well as the political context of Kant’s project. The third part of the article offers a detailed analysis of Kant’s proposals with regard to the institutional construction of constitutional republics and of a global federation of peoples. The author concludes that from the perspective of the ‘second Modernity,’ the experience of early Modern philosophers might assist in resuming a more active dialogue between philosophers and political leaders, as well as inviting contemporary philosophers to take a leadership role in the institutional construction of preconditions for civil peace and the prevention of wars in Eastern Europe.
Traditional Values as a Post-Secular Construct in the Post-Soviet Context: the “pillars” of the “Russian World” vs. Ukraine’s “Revolution of Values”
Authors:   Ukrainian Catholic University, Cherenkov Mykhailo
Published: May 2023

“T raditional Values” proved a construct, a noticeable marker of the post-secular age, one that is in demand in the post-Soviet context. The hybrid nature of these traditional values made them serviceable as a secret “weapon of mass destruction” in the hybrid Russia- Ukraine war. Non-critical use of this construct is dangerous, as it activates the religious unconscious, and quickens destructive collective reactions. It is for precisely these reasons that the author offers a deconstruction of the social- philosophical framework that legitimizes these values, and the very way they are produced in society. The article argues that the demand for tradition turns out to be the demand for the manipulative effect from the use of tradition. The same goes for religion in general – post-secularity is not interested in religion per se, but in those potentialities of religion that are able to endlessly magnify the effect of manipulating social consciousness. So the patrons manage to mobilize society by manipulating its traditionalist demands, but offering pseudo-morphosis, rather than a holistic and authentic tradition. In the case of the post-Soviet space, and the Russian-Ukrainian antagonism, we see the clash of two value-worlds: the Russian society, united around “traditional values,” and the Ukrainian society, joined by “European values.” In the former instance, values are seen as “pillars” of a closed society, in the latter – as expressions of dignity and freedom as the condition of an open society. However, in both instances the values confessed stake a claim to traditionality, or are inscribed into a tradition that a particular society perceives as its own, defining and continuous, normative and even sacred. As the author shows, the orthodoxy of “traditional values” is fairly problematic, so their religious and public- theological use must be supplemented with a critical philosophical analysis.

Published: May 2023

This article examines the influence of Borys Hrinchenko’s puristic principles, which he articulated on the pages of the Lviv semimonthly Zoria during the years 1891–93, on his poetic lexicon. Our research shows that the number of words per textual unit in Hrinchenko’s poetry is 35.7 per cent less than in Ivan Franko’s poetry of the same period (1,939 words vs. 2,631 various words per 8,000 words of text). The number of identical Russian and Ukrainian words was 319 (12.1 per cent) in Franko’s poems and 278 (14.3 per cent) in Hrinchenko’s (i.e., 36.1 words in Franko vs. 30.8 in Hrinchenko per 1,000 words of text). The number of identical Polish and Ukrainian words was 245 (9.3 per cent) in Franko and 188 (9.7 percent) in Hrinchenko (i.e., 34.2 in Franko and 37.3 in Hrinchenko per 1,000 words of text). Violations of the monotonicity of dependence of identical Ukrainian, Russian, and Polish consonants on the frequency these words occur clearly indicate that the “failure” of monotonicity is greater vis-à-vis the Russian language. The hypothesis that this non-monotonicity and poorer lexicon result from Hrinchenko’s purism is substantiated. By cleansing the language of his poems of evident Russianisms, he reduced the proportion of identical Ukrainian and Russian words by only 5 per cent. Meanwhile such words are fewer in Franko’s “uncleansed” language by 17 per cent. Hrinchenko’s principles did not, in fact, distance Ukrainian from Russian, but they led to impoverishment of the Ukrainian lexicon and diminished the ability of the language to convey semantic nuances, thereby harming its communicative functions.
The “Missing Column”: Contemporary Editions of Vasyl’ Shakhrai’s and Serhii Mazlakh’s Works and the Significance of National Communism for Ukrainian Historiography
Authors:   Bashkortostan Republican Museum, Haukhman Mykhailo
Published: May 2023

This article deals with two of the earliest works by Ukrainian Bolsheviks: Revoliutsiia na Ukraine (1918) by V. Skorovstanskii (pseud. of Vasyl’ Shakhrai) and Do khvyli (Shcho diietsia na Vkraїni ta z Ukraїnoiu?) (1919) by Serhii Mazlakh and Vasyl’ Shakh-Rai (pseud. of Shakhrai). Both of them were expelled from the Bolshevik Party because they presented arguments in support of Ukraine’s independence from Soviet Russia and for the creation of a future Ukrainian Communist Party. The above works were republished in Odesa in 2017 and 2019 respectively along with additional documents and forewords and afterwords by Andrii Zdorov and Artem Klymenko, two left- wing historians living in Ukraine today. The legacy of Ukrainian national communism of the revolutionary and post- revolutionary years of 1917–21 has generally been missing from Ukrainian intellectual thought until recent times. A significant and interesting exception occurred during Perestroika in 1988, when the Soviet Ukrainian historian Iurii Hamrets’kyi promoted (without success) the political rehabilitation of the revolutionary “heretic” Shakhrai and proposed a revision of the Soviet narrative of the October Revolution and ensuing war in Ukraine. Within two to three years, along with the collapse of the Soviet regime and the USSR, the official Soviet narratives of Ukraine’s history lost their value. Shakhrai’s and Mazlakh’s works, who were simultaneously Ukrainian patriots and Bolsheviks, counter the stereotypes of Ukrainian ethnonational historiography. Their writings are a correction not only to the contemporary narrative of the “Ukrainian Revolution”, but also of the Soviet narrative of “the Great October Revolution” and the “Russian Civil War”.

In this modern era, it is important for teachers to use Android as a learning medium. This aims to facilitate the learning process. The purpose of this study was to test the validity, practicality, and effectiveness of Android-assisted learning media to improve junior high school students' thinking skills. This study used the ADDIE model with 30 students of Rengat 1 Public Middle School as research subjects. The instruments used are non-test instruments in the form of validation sheets and practicality sheets. For data collection techniques, namely by taking validation data, practicality data and effectiveness to students. The data analysis technique used is to conduct product validation tests on experts, practicality and effectiveness tests on students. From the research results, it was found that the media was already in very valid results with a percentage of 88.25%, and for practical results a percentage of 80.26% was obtained with a very practical category. The effectiveness results showed that the pretest results of students who achieved KKM were only 20%, and the posttest of students who achieved KKM increased by 80%. This makes the learning media ready to be used by the teacher to students in the classroom.

Authors: abid Abbas Abdul Hussein , Muhammad Hussein Burhan
Published: May 2023

The aim of this study was to evaluate tensile properties of low and medium carbon ferrite -martensite dual phase steel, and the effect cryogenic treatment at liquid nitrogen temperature (-196 ºC) on its properties. Low carbon steel (C12D) and medium carbon steels (C32D & C42D) were used in this work. For each steel grade, five groups of specimens were prepared according to the type of heat treatment. The first group was normalized, the second group was normalized and subsequently subjected to cryogenic treatment then tempered at (200 ºC) for one hour, the third group was quenched from intercritical annealing temperature of (760 ºC) to obtain dual phase (DP) steel, the fourth and fifth groups were both quenched from (760 ºC), but the forth group was subjected to cryogenic treatment and the fifth group was subjected to cryogenic then tempered at (200 ºC) for one hour. Mechanical tests were carried out which includes, tensile, hardness, as well as microscopic examination. Yield strength, ultimate tensile strength and ductility for DP were correlated to martensite volume fraction. The yield and tensile strength (σy, σu) of (DP) for the three steels, were higher than those of normalized condition, and increased after cryogenic treatment. These values, for the three steel grades, decreased after tempering at temperature 200 ºC. Tempering of (DP) steel at 200ºC for one hour, after cryogenic treatment, causes the reappearance of yielding point for steels (C12D) and (C32D) while no such a change noticed in (C42D) steel. The results have shown that hardness of (DP) increased after cryogenic treatment for the three steel grades.
