Pedagogical Recognition
Authors: Ayala Raquel
Published: January 2019

Pedagogical activity, be it of parents or teachers, continuously requires us to meet children's and youngsters' deep ethical needs. In our daily relationships with them, recognition is one of the most frequent and essential ingredients of our educational activity. But, what does being recognized mean? When does this everyday practice become genuinely pedagogical?

This phenomenological inquiry explores pedagogical recognition, an experience of an essentially ethical sense. Through our words, actions, decisions, etc., we offer children and young people effective learning experiences about what is good and right in our human world. Moreover, genuine recognition allows us to discover the personal worth and uniqueness of every child and young person entrusted to us. Recognition deals with the very being of people revealed through their capabilities in action.

In this experience, the educator plays the decisive role. Thanks to our pedagogical responsibility and influence, we have the power to recognize; a power that has been given to us by the child and that can be observed when the transformational effect of recognition occurs. Pedagogical authority is the foundation of recognition as well as educational intentionality. The pedagogical significance of this practice requires every educator to evaluate and to improve the ways of doing this effectively, especially by thinking carefully about every person's singularity and by developing awareness of our ethical personality and our embodied language. It may lead us to being recognition.
Living with Bodily Changes after Weight Loss Surgery - Women’s Experiences of Food and "Dumping"
Authors: Groven Karen Synne , Engelsrud Gunn , Råheim Målfrid
Published: January 2019

In this article we explore women’s experiences of “dumping” following weight loss surgery. The empirical material is based on individual interviews with 22 Norwegian women. To further analyze their experiences, we build primarily on the phenomenologist Drew Leder`s notion of the “inner body.” Additionally, Simone de Beauvoir and Merleau-Ponty’s perspectives of the lived body occupy a prime framework for shedding light on different dimensions of bodily changes. The following three core themes were identified: Experiences of illness in conjunction with eating; Learning to relate to changes in the inner body and; Feelings of losing and regaining control. In different, though interconnected ways, these themes encompass an ongoing challenge in the women’s lives after the surgery: namely their efforts to establish new eating habits while at the same time working hard to relate to their changed and changing inner body, and especially to the phenomenon of “dumping”. The results points to a dilemma: namely that the gastric bypass procedure is an operation that irreversibly alters the anatomy and physiology of a healthy stomach, whereas the individual’s eating habits cannot be situated in or reduced to a particular organ, but are endemic to the lived body and its history. This insight might be of importance in the understanding of the complexity of the changes and challenges the women go through after weight loss surgery.
Understanding the Experience of Discovering a Kindred Spirit Connection: A Phenomenological Study
Authors: Finlay Linda , Eatough Virginia
Published: January 2019

Preliminary existential hermeneutic phenomenological analysis of data based on 24 protocols, and our own reflexive discussion, reveals how “kindred spirit connections” manifest in myriad elusive, evocative ways. These special connections are experienced variously from briefly felt moments of friendship to enduringly profound body-soul love connections. This paper explicates five intertwined dimensions: shared bonding; the mutual exchange and affirmation of fellowship; the destined meeting or relationship; immediate bodily-felt attraction; and the pervasive presence of love. A wide ranging literature around the theme of love is outlined and the concept of kindred spirit is briefly applied to the psychotherapy practice context.
Living in a Minority Food Culture: A Phenomenological Investigation of Being Vegetarian/Vegan
Authors: Edwards Sachi
Published: January 2019

This phenomenological investigation aims to explore the lived experience of being vegan or vegetarian in a society and culture that is primarily non-vegetarian. As members of a unique minority group, vegans and vegetarians can sometimes be misunderstood by non-vegetarians and stereotyped as judgmental or difficult to deal with. Living with this type of misunderstanding from others can lead to feelings such as worry, loneliness, and fear. As such, the use of phenomenological inquiry is well suited to uncover the lived experience this phenomenon in such a way that no other method of inquiry could. The author brings forward themes that emerged from in depth conversations with two vegan/vegetarian participants, and draws from her own personal experiences as a vegetarian to supplement the data and further uncover the phenomenon. Themes are brought forward through the use of, among other works, Hyppolite’s (1956) and Bachelard’s (1994) descriptions of “inside vs. outside” and van Manen and Levering’s (1996) notion of secrecy.
Re-storing the Earth: A Phenomenological Study of Living Sustainably
Authors: Buckley Jessica
Published: January 2019

Living sustainably evokes ideas of lived, bodily engagement with and perception of the earth. Yet, modern ways of thinking and speaking have slowly alienated the earth from consciousness. Using phenomenological methods, the author examines the experience of living sustainably, exploring her own background and the idea of restoring the earth to consciousness, before examining the lives of two students dedicated to living sustainably. Components of upholding the earth, in-volving humanity, perceiving differences in studying and embodying sustainability, and engaging in choices fill the experience of living sustainably.
Klaus Mollenhauer's "Forgotten Connections": A sketch of a general pedagogic
Authors: Wivestad Stein M.
Published: January 2019

Mollenhauer presents his book as a rough sketch of what Allgemeine Pädagogik (General Pedagogic) could be – an outline of "a general study of Bildung and upbringing" (Mollenhauer, 2014, p. 9) – a daring project, which in my view is even more needed today than in 1983. Mollenhauer shows a way to a practically committed, historically-founded and future-oriented theory of emancipatory upbringing and education; built on reliable elements in the cultural and pedagogical tradition, which we, as responsible adults, should not forget, when we, together with the new generation, face present and future challenges. In this essay, I attempt a short interpretation of his sketch and give some brief evaluative comments in the final section.

Trading in Imaginaries: Locating Authenticity in Argentine Tango
Authors: Barnstaple Rebecca
Published: January 2019

Argentine tango tends to be associated with highly gendered images of women and men locked in contorted embraces. These images constitute a tango imaginary that is removed from the lived experience of the dance. Remaining close to the experiential core of tango, this paper provides a Heideggerian-inspired phenomenological account that re-imagines tango as a mode of being-in-the-world. By situating us in direct and constant relationship with an attentive partner and furnishing a complex grammar of constraints, tango generates a frame for creating and sustaining worldhood. By examining the how of dance, the kind of experience it offers up, we approach the dynamic emergence of Being. In what follows, I draw on my years of dancing tango to elaborate an understanding of the experiential dimensions of the dance, and how these relate to the development of shared focal practices that disclose insights associated with embodied being-in-the-world.

Published: January 2019

The purpose of this study is to derive practical implications for activating mathematics class using mathematical modeling by analyzing the teaching and learning activities in the process of applying a mathematical modeling task. For this study, we developed a mathematical modeling program titled as ‘Amount of Milk’, and analyzed the results after applying it to nineteen 6th grade students of O elementary school in Seoul. In order to activate mathematics class using mathematical modeling, we have to consider the followings. First, detailed programs and training for teachers are needed. Second, teachers' efforts to use mathematical modeling programs are most important. Third, we need to allot students as effective groups. Forth, we have to develop suitable tasks and programs for modeling class. Finally, we need to have enough time to do modeling activities using modeling tasks.

Published: January 2019

In order to examine the recent international research trends in mathematics education, the titles announced at the 2017 international conference of mathematics education were analyzed using the Language Network Analysis Method. We examined the frequency of the words mentioned in 1,201 titles and the meaning of node linking word to word. The trend of 2017 math education research can be described as “For the professional development, teacher encourages learning using words problem, problem solving and problem posing, and makes teaching and learning with formative assessment so that students can build basic learning and conceptual understanding.” As a result of exploring recent topics that be sparsely reseacrched in Korea, there have been ‘productive struggle’, ‘number sense’, ‘social justice’, and ‘formative assessment’.
Praxeology-based Analysis and Design of Mathematical Tasks: A Case of Analysis and Design of Tasks about the Sum of Interior Angles of a Polygon by an Inquiry Community
Authors:   The Korea Society Of Educational Studies In Mathematics, Lee Kyeong-Hwa , Song Chang-Geun , Lee Deok-Young
Published: January 2019

Praxeology is a fundamental concept in Anthropological Theory of the Didactic established by Chevallard. This study examined the meanings and significance of praxeology-based analysis and design of mathematical tasks theoretically and empirically. We first clarified the meanings of praxeology-based analysis and design through theoretical review on literature. Then we reported the significance of praxeology-based analysis and design by exploring previous research. Finally, we validated those meanings and significance through empirical analysis on the case of praxeology-based analysis and design of the mathematical tasks about sum of interior angles of a polygon, which is conducted by a researcher-teacher inquiry community. Two implications are obtained from this study. First, through praxeology-based analysis on mathematical tasks, one can capture and discuss the detailed contents and forms of external didactic transposition which is facilitated by didactic noosphere. The impact of external didactic transposition on classroom instruction and practical suggestions for external didactic transposition can be illustrated by and induced from praxeology- based analysis. Second, teachers who plan their lessons based on designed tasks can utilize praxeology of mathematical tasks as a basic framework. Teachers can plan, analyze and understand their lessons using praxeology.

Aboriginal domestic tourism leadership towards reconciliation in Australia
Authors: Jacobsen Damien
Published: January 2019

The worldmaking possibilities of domestic tourism provide Aboriginal and Torres Strait Islander people in Australia with the potential to take leadership over the challenging interpersonal encounters necessary to the process of reconciliation. This proposition is drawn from a philosophical hermeneutic view of domestic tourism hosts and guests as always already bound by complex histories they cannot change. The paper demonstrates that tourism can enable Aboriginal and Torres Strait Islander people to operate enterprises based on customary cultural law of neutral meeting places attuned to the difficult interpersonal challenges of Reconciliation. Neutral meeting places do not impose reconciliation onto domestic tourists, the intent is to instead exercise everyday humanity and compassion while enabling visitors to fulfil their travel desires. The findings suggest that visitors can become oriented to Aboriginal ways of being and stimulated to learn. As interactions progress, visitors can reach readiness to take up opportunities for genuine dialogue with Aboriginal hosts. Outcomes raised in this paper highlight that tourism can enable Aboriginal and Torres Strait Islanders, as colonised people, to implement their cultural authority to take leadership over perplexing historical legacies woven through the fabric of a Western-dominated society conditioned by colonialism.
Some aspects of fretting fatigue under cyclic normal loading
Authors: Abbasi Farshad , Majzoobi G. H.
Published: January 2019

Fretting fatigue has been studied mainly under constant normal loading, as it requires simple equipment which can be assembled on a universal fatigue testing machine. Recently, we [1] have introduced an innovative fretting fatigue apparatus in which the contact pressure can independently be varied during the test. In a recent publication [2] we have investigated the effect of normal load frequency on fretting fatigue life of Al7075-T6 under cyclic normal load condition. It was found that the low frequency of normal load has drastic effect on fretting fatigue life. The effect, however, gradually diminishes with the frequency increase and vanishes at the frequency of around 80Hz. In another publication [3] we have compared the results of constant normal loading with those of in phase, 90° and 180° degrees out-of-phase loadings. It was found that the constant normal loading has the least fretting damage, while the maximum fretting damage occurs by in-phase loading. The results also showed that the out-of-phase loading had improving effect on fretting fatigue life with respect to the in-phase condition. Recently, Ciaverella [4] has published a discussion on our publications [2, 3]. He believes that some of our experimental results needs further discussion. Therefore, the objective of this article is to answer three main points he has raised in his article [4]. We hope that this discussion could lead to some progress.

The aim — to evaluate the efficacy and safety of addition of a solution containing 4.2 g of arginine hydrochloride and 2.0 g L‑carnitine to standard therapy of patients with acute coronary syndrome (ACS) with ST segment elevation and concomitant type 2 diabetes mellitus (DM) after revascularization through primary coronary intervention (PCI).Materials and methods. The study involved 60 patients (mean age 64.3 ± 1.6 years) with ACS with ST segment elevation of up to 6 hours’ duration and concomitant type 2 DM, who had had urgent coronary angiography and stenting of the infarction‑dependent artery. The patients were divided into two groups: group І — 30 persons to whom standard intravenous infusion was given of a preparation containing 4.2 g of arginine hydrochloride and 2.0 g of L‑carnitine, 100 ml a day for 7 days, and group ІІ — 30 individuals who did not receive additional therapy. A general clinical examination was conducted with an assessment of complaints and anamnesis, objective physical examination data and the results of additional diagnostic methods. The level of troponin I and resolution of ST segment were determined on the 1st, 3rd and 7th days.Results and discussion. Patients in both groups were compared according to the main clinical and anthropometric indices, prescribed drug therapy, features of atherosclerotic damage of coronary artery, duration of ischemic period, troponin I level on the 1st, 3rd and 7th days (all p > 0.05). The value of ST segment elevation at the time of hospitalization in the patients of both groups did not differ significantly: 4.8 ± 0.17 and 4.5 ± 0.15 mm respectively, but on day 3 it was lower in group І (2.37 ± 0.14 mm) compared with group II 3.2 ± 0.17 mm, p = 0.05). In patients of group I, unlike such of group II, there was a significant decrease in the level of aspartate aminotransferase and alanine aminotransferase on day 7. The decrease in group I was more pronounced than in group II (p = 0.048 and p = 0.032, respectively).Conclusions. The addition of amino acids complexes (4.2g of arginine hydrochloride and 2.0 g of L‑carnitine) to drug therapy of patients with ACS with ST segment elevation and concomitant DM type 2 after myocardial revascularization, contributes to a rapid decrease in the level of troponin I and reduction in ST segment elevation and is not accompanied by side effects.

Authors: E. V. Aksenov
Published: January 2019

The aim — to analyze the risk factors for periprocedural complications during recanalization of chronic coronary artery (CA) occlusions in patients with coronary artery disease.Materials and methods. The study included 365 patients with chronic of CA occlusions, which, on the basis of X‑ray angiography department of M. M. Amosov National Institute of Cardiovascular Surgery of National Academy of Medical Sciences of Ukraine underwent diagnostic and therapeutic intervention procedures for this pathology. The patients’ age was from 62 to 73 years old (average age — 66.96 ± 1.81 years). Occlusions were localized mainly in the proximal (167 (45.8 %) cases) and middle (198 (54.2 %) CA segments. The duration of occlusion was determined from the time of myocardial infarction in the infarct‑related CA pool. Occlusion duration from 3 to 6 months was recorded in 98 (26.8 %) patients, from 6 to 12 months — in 137 (37.5 %) patients, from 1 to 3 years — in 130 (35.6 %) patients. Chronic occlusion of one CA was detected in 93 (25.5 %) persons, two CA — in 127 (34.79 %) persons, three CA — in 56 (15.3 %) persons. In 89 (24.38 %) patients, multiple atherosclerotic lesions of the coronary bed were diagnosed. Mean number of affected CA in one patient was 2.17 ± 0.34.Results and discussion. Out of 235 patients with the term of occlusion up to 1 year, a good angiographic result was achieved in 87.2 %, out of 130 persons with occlusion duration of 1— 3 years — in 72.3 %. The average number of implanted stents was 2.12 ± 0.3 per one patient. 51 (13.97 %) patients had periprocedural complications. The development of «big» complications of X‑ray endovascular coronary interventions for chronic occlusion of CA was statistically significantly influenced by the patient’s age and smoking (p < 0.05), the probability of developing «small» periprocedural complications — by body mass index and diabetes.Conclusions. Risk factors for the development of «big» complications are femoral access, the duration of the procedure and fluoroscopy, the amount of contrast material used during the procedure.

Published: January 2019

The aim —  to investigate the results of treatment with L‑arginine of patients with intermittent claudication for prevention of critical stages of limb ischemia.Materials and methods. 86 patients with intermittent claudication were randomly divided into two groups of 43 patients each. Patients of the first group received 8 g of L‑arginine (Tivortin) twice a day, patients of the second group — 40 mg of prostaglandin E1 (PGE1) twice a day.Results and discussion. Administration of L‑arginine contributed to an increase in the distance of painless walk by 230 ± 63 %, the absolute walk distance — by 155 ± 48 % (p < 0.05), the administration of PGE1 — by 209 ± 63 % and 144 ± 28 %, respectively (p < 0.05). Treatment with L‑arginine increased the value of the coefficient of L‑arginine/asymmetric dimethylarginine in plasma and the excretion of nitrates and cGMP in the urine, which indicated the normalization of the biosynthesis of endogenous NO. PGE1 therapy did not significantly affect endothelium‑dependent vasodilation parameters. The coefficient of quality of life, estimated in an analog scale, increased from 3.51 ± 0.18 to 8.3 ± 0.4 in the arginine group and to 7.0 ± 0.5 in the PGE1 group (all p < 0.05).Conclusions. Arginine is a drug of choice to prevention of severe forms of lower limbs ischemia and other manifestations of multifocal atherosclerosis.

Published: January 2019

The actual task in the field of computer-aided design of machine-building objects is to increase the level of automation of structural-parametric analysis of design solutions due to the repetition of their use, reducing the number of design operations and ensuring the corresponding competencies of designers. Developed methods and algorithms should ensure the acquisition of the necessary competencies for the designer for successful project activities in the field of computer-aided design, increasing the effectiveness of training. The system of analysis of design solutions should improve the quality of design solutions implemented in CAD KOMPAS-3D.

In this paper, an overview of methods, systems and tools for analyzing design solutions implemented in the CAD-3D environment. The main features of such systems are described, their main disadvantages are identified: the lack of functions for determining non-optimal sequences of design operations, the inability to automatically rebuild a three-dimensional model of a machine-building product on the basis of analysis of the design model tree. A complex system for the analysis of project solutions and the training of a designer was developed and implemented, based on methods, models and algorithms for analysis and adaptive learning. The results of a computational experiment are presented, on the basis of which it can be concluded that the use of developed software enhances the efficiency and quality of the designer's training in the processes of constructing three-dimensional solid-state machine-building products in CAD KOMPAS-3D.

Published: January 2019

Present study deals with the optimization of various culture conditions for initiating high frequency in vitro shoot multiplication in two early maturing high yielding sugarcane genotypes namely Co98014 & Co89003. On the behalf of the findings of this study, it was concluded that the temperature, photoperiod and culture media pH affected the frequency of in vitro shoot multiplication in both sugarcane genotypes at a significant level. In both genotypes high frequency shoot multiplication was recorded at growth room temperature 25ºC, 16h/8h light/dark photoperiod and culture media pH 6.0. Genotype Co89003 exhibited highest shoot regeneration and multiplication under various culture conditions. The present study suggests the necessity of investigation of these culture conditions separately upon individual sugarcane genotypes prior to develop efficient in vitro plant regeneration protocol for commercial purposes.

Published: January 2019

The present investigation was carried out with fifty six genotypes involving 10 parents, their 45 F1s hybrids and one check hybrid in tarai region of Uttarakhand. The presence of more amount of variance due to SCA effects than GCA effects in our experimental material indicated that heterosis breeding is better choice. The good general combiners were P1, P3 and P4 for ear length; P8 for ear diameter; P5 and P8 for number of kernel rows per ear; P1 and P4 for number of kernels per row, P8 and P9 for100-kernel weight and P5 for grain yield, which can be utilized directly or indirectly in breeding programme. The best eight specific combiners for grain yield were P1xP8, P4xP10, P7xP8, P5xP8, P5xP9, P4xP9, P1xP2 and P5xP10 involving average x average, good x average, good x poor and average x poor parental combinations of generalcombining ability indicating the presence of non-additive gene action. The nine crosses, P1xP2, P1 xP5, P1xP8, P4xP9, P4xP10, P5 xP8, P5xP9, P5xP10 and P7xP8 had positive significant per cent heterosis for grain yield, and crosses namely P1xP4, P1xP5 and P1xP8 for ear length; P1xP3 and P1xP5 for number of kernels per row and P1xP8 and P9x P10 for 100-kernel weight were having positive significant per cent heterosis at 1% and/or 5% level of significance for respective traits. The crosses, P1xP2, P1xP8, P4xP9 andP7xP8 manifested high SCA effects along with excellent standard heterosis and per se performance for grain yield and also for most of the studied characters, therefore, classified as potential hybrids.

The vagaries of Climate Change variability need to be addressed and as climatic conditions change at particular experimental sites and maize producing regions, mega-environment assignments will need to be reassessed to guide breeders to appropriate new germplasm and target environments . The development of improved germplasm to meet the needs of future generations in light of climate change and population growth is of the upmost importance . Evaluation of the inbred lines from diverse ecosystems would be effective for production of lines with resilience towards climate variability. Hence, with this objective diverse set of inbred lines sourced from all over India were characterized and were evaluated with DIVA-GIS for diversity analysis of maize inbred lines. Grid maps generated for these maize inbred lines for eleven quantitative traits indicated that these lines can be sourced from North and South India. High Shannon diversity index with maximum range of 2.17-3.0, 2.25-3.0, 2.36-3.0, 2.4-4.0, 2.0-3.0, and 2.2-3.0 were recorded for the traits viz; plant height, ear height, grain weight, grain yield, kernel row and protein content respectively indicating the high response of these traits to ecosystem. However, inbred lines were found to be diverse for all the traits except for ears plant-1 (EPP) and they have been sourced from Northern and Southern parts of India while for EPP recorded less diversity index range of 0.4-1.0 indicating source from South India. Interestingly, less diverse inbred lines for all the eleven quantitative traits have been sourced from Indogangetic plains as indicated in diversity grid maps. Maximum diversity indices were recorded for anthesis silking interval (ASI), days to silking, days to tasseling, which are in the range of 0.97-2.0, 1.528-2.0, 1.516-2.0 and 1.528-2.0 respectively. Hence, DIVA-GIS enabled identification of diverse sources from varied ecosystems which can be used for developing improved lines/ cultivars with greater resilience towards climate change.
Efficacy of anthranilic insecticide E2Y45 20 SC (Chlorantraniliprole) against Plutella xylostella L. in cabbage, Brassica oleracea var. capitata
Authors: Sharma Sudhendu , Singh Ravinder , Gill C. K.
Published: January 2019

Experiments were conducted at farmer’s cabbage fields to evaluate the bioefficacy of anthranilic insecticide i.e. E2Y45 20 SC (Chlorantraniliprole) having novel mode of action against the diamondback moth Plutella xylostella L. E2Y45 20 SC was applied @ 25.0, 37.5 and 50.0 ml/ha and was compared with Padan 50 SP (cartap hydrochloride) @ 500 g/ha and the untreated control. Lowest mean larval population after two sprays was recorded in higher dose of E2Y 45 20 SC i.e. @ 50.0 ml/ha (0.08 larvae/plant) at 7 days after treatment followed by medium and lower dose of E2Y 45 20 SC i.e. @ 37.5ml/ha (0.10 larvae/plant) and 25.0 ml/ha (0.33 larvae/plant). The larval population in these treatments was significantly lower than standard check, Padan 50 SP (2.56 larvae/plant), and untreated control (9.73 larvae/plant). The highest marketable yield (262.89 q/ha) was recorded in E2Y 45 20 SC @ 50.0 ml/ha which was significantly higher than Padan 50 SP (239.65 q/ha). Lowest yields were recorded in untreated control (106.00 q/ha). Conclusively, medium (37.5 ml/ha) and higher (50.0 ml/ha) dose of E2Y 45 20 SC (chlorantraniliprole) significantly reduced the larval population of P. xylostella and increased the cabbage yield.

Published: January 2019

The present investigation was carried out to identify desirable parents and F1 hybrids in okra by involving eight diverse parents in a diallel mating design excluding reciprocals. Genotypes i.e., P-20 and VRO-4 for earliness; 9801 for first fruit producing node (-0.085), internodal length (-0.659) and fruit length (0.201); HU for average fruit weight (0.603); Tulsi-I for nodes per plant (0.429), fruit length (0.271) and plant height (12.068) were found good general combiners appeared to be worthy of exploitation in future breeding. It is suggested that involving these lines, new genotypes may be developed through multiple crossing for isolating high yielding varieties. The cross combinations VRO-4 × HU, Tulsi-I × SKBS-11, P-20 × Tulsi-I and P-8 × Tulsi-I showed high SCA effects as well as per se performance for yield per plant. The crosses showing high SCA effects and per se performance for yield per plant suggested that these hybrids may be exploited in further breeding programme.

Ascorbic acid and total phenol in frozen aonla pulp on zero day of storage was found to be 365.5 mg/100g and 2.1 mg/g while in dehydrated aonla pulp it was 2.3 mg/100mg and 14.7 mg/g which was found to decrease with the increase in storage duration. However, significant increase (CD at 5% Level) in total soluble solids (TSS) and non-enzymatic browning was noticed with the advancement in storage duration. The decrease and increase in physico-chemical characteristics were more significant in dehydrated aonla pulp as compared to frozen aonla pulp. Mean score for sensory attributes of dehydrated aonla pulp at zero month of storage was fairly less than frozen aonla pulp. Moreover, there was more significant decrease in value of sensory attributes of dehydrated aonla pulp during six months storage period compared to frozen aonla pulp. Thus, present study was first in its kind to determine and compare chemical composition and overall acceptability of frozen and dehydrated aonla pulp obtained from aonla fruits cv. Chakaiya during storage for optimizing there use in further development of value added aonla product.

Published: January 2019

The present laboratory study was conducted to determine the effect of chlorpyrifos on growth and reproduction of the earthworm Eudrilus eugeniae. Chlorpyrifos was mixed with soil substrate at four different dose formulations i.e. D1 (2.5ml/1000ml); D2 (5.0ml/1000ml); D3 (7.5ml/1000ml); D4 (10.0ml/1000ml). Soil substrate withoutchlorpyrifos served as control. Growth and survival rates were determined till four weeks and effects on reproduction are assessed after eight weeks of exposure. A non significant decrease (p > 0.05) was observed in body weight of earthworms which was recorded on day 1, 2, 3, 7, 10 and 14. A dose dependent effect on cocoon production and survivability of hatchlings was observed in all treated groups. The effect of chlorpyrifos on life cycle of earthworm was more in dose D3 (54.25 days) when compared to control (28.75 days) while no worm survived in D4 dose. The present study revealed that chlorpyrifos at high dose levels(7.5ml/1000ml and 10.0ml/1000ml) affect the reproduction and growth of earthworms, primary bioindicators of soil fauna, whereas the base dose (5.0ml/1000ml) may be considered as safe for soil applications.

Published: January 2019

In the present study, morphological and molecular markers (RAPD primers) were used to analyze the genetic diversity and genetic relationships among 21 accessions of Echinochloa spp. complex comprising the wild and cultivated species collected from Melghat and adjoining regions of Vidarbha, Maharashtra. The availability of diverse genetic resources is a prerequisite for genetic improvement of any crop including barnyard millet. A high degree of molecular diversity among the landraces was detected. Among the 21 genotypes, two major groups (A and B) were formed, at 67.28 % similarity, which clearly encompasses 15 accessions of E. frumentacea and 6 accessions of E. colona. Higher similarity was observed in accessions of E. frumentacea. The accessions IC 597322 and IC 597323 also IC 597302 and IC 597304 showed more than 94% similarity among themselves. The classification of genetic diversity has enabled clear-cut grouping of barnyard millet accessions into two morphological races (E. frumentacea and E. colona).

Authors: Padmapriya C. , Murugesan R.
Published: January 2019

Pencillium purpurogenum 8904.12, a red pigment producer, was isolated from soil screened and selected based on the pigment production. The pigment production by P.purpurogenum was optimizedby using factorial design and Response Surface Methodology (RSM) in SSF. Cassava waste is a low cost and nutrient rich substrate used in this study as a substrate. RSM based central composite design was employed to obtain best combination of substrate concentration, inoculum volume, incubation time, initial moisture and initial pH. By the point prediction tool of Design-Expert 8.0, the optimum values of the factors for maximum red pigment production were determined. Under the optimized conditions (substrate concentration 10 g, inoculum volume 5 ml, 15 days incubation time, 50 % initial moisture and initial pH of 6), the red pigment yield was 28.33 colour value units / g of dry fermented substrate which agreed closely with the predicted yield. The model showed that the value of R2 (0.9936) was high and pvalue of interaction of variance was <0.0001. Hence the model can be said to be of highly significant. A significant Increase in red pigment production was achieved using RSM. Thus, utilization of cassava waste for red pigment production in this study could provide the most effective use of cassava resource, and lead to technology of development for its further utilization and value addition.

This study evaluates the impacts of possible future climate change scenarios on the hydrology of the catchment area of the Manjalar sub basin of River Vaigai, Tamil Nadu, India carried out at the department of Soil and Water Conservation Engineering, Tamil Nadu Agricultural University during the period of 2011-2014 using Soiland Water Assessment Tool (SWAT). For the climate impact assessment the hydrological model was driven with output of bias corrected Earth System Models of the Coupled Model Intercomparison Project Phase 5 (CMIP5): HadGEM2. Climate scenarios were downscaled to a grid resolution of 0.22° x 0.22°. In this study RCP 4.5 and RCP 8.5 were included for future assessment with three future periods: 2012–2039, 2040–2069, and 2070–2098. The projected increase in maximum and minimum temperature for RCP 4.5 scenario is 0.8 to 2.3 ºC and 0.7 to 1.6 ºC and for RCP 8.5 scenario is 1.1 to 4.0 ºC and 1.0 to 3.1 ºC, respectively. Rainfall is projected to an increase between 9.2 to 15.2 per cent for RCP 4.5 scenario and an increase of 13.6 to 18.8 per cent for RCP 8.5 scenario during 21st century. The soil water storage and stream flow contribution to ground water are likely to increase in RCP 4.5 scenario and it would again decline for RCP 8.5 scenario during 21st century. The increase in annual rainfall evapotranspiration and surface runoff would be more in RCP 8.5 scenario compared to RCP 4.5 scenario. The possible changes projected by the study provide a useful input to effective planning of water resources of the study area.

Published: January 2019

In the present investigation, various forms of sulphur (S) viz., total S, organic S, inorganic S and available S were estimated in soils under four different land uses viz., Rice-rice, rice-green gram, mango orchard and a fallow. Soils samples were taken up to a profile depth of 0.60m at 3 depths i.e. 0-0.20m, 0.20-0.40m and 0.40-0.60m. Thesoils were found to be slightly acidic to moderately acidic in reaction (5.83-6.59), showing an increase along the depth irrespective of the land use pattern. Soil organic carbon (SOC) content (mean 5.5 gkg-1) was found well above the low level of SOC in soils. Calcium carbonate content, bulk density and clay content of soils didn’t maintain any definite pattern along the depth. All forms of S were found to decrease along depth irrespective of the land use patterns. The available S content ranged from 12.2 to 21.4mgkg-1 of soils. The relative preponderance of all the forms of S followed the order: mango orchard> fallow> rice-rice> rice-green gram. On an average organic S and available S fractions constituted 93 and 6 per cent of total S respectively. A correlation matrix revealed that all the forms of S maintained a significant positive correlation with SOC content while a negative correlation with pH of the soils. The results of the study will be useful in managing the different fractions of S in soils in order to maintain its availability well above the critical level.
