Following the Footsteps of Russian Tuvian Folk Music Scientists
Authors: Kyrgys Zoya Kyrgysovna , Ondar Bady-Dorzhu Vladimirovich
Published: August 2023

This article aims to highlight the significance of song folklore recordings when documenting the scientific heritage of the first scientists and researchers of Tuvan musical folklore—A. N. Aksenov and E. V. Gippius—during the period 1927 to 1965. The methodological basis consists of the principles of historical continuity, objectivity, a holistic approach to the analysis of the history of the development of traditional Tuvan vocal music and the prospects for its development. The study of folk music is inextricably linked with the development of professional art. Currently, the works of visiting Soviet composers, melodically associated with Tuvan folklore, are practically not performed in the repertoire of concert programs of creative collectives of the city of Kyzyl. One of the main obstacles to their further application is the absence of these works in the curricula in music educational institutions. The issues of the prospects for the use of preserved sources in the digital archive of the Academy "Xөөmei" are analyzed. The question is raised about the need to create a single institutional repository of works and materials on the work of Russian specialists, musicologists, and scientists who studied the musical culture of Tuvinians in the Soviet period. Modern Tuvan musical folklore was largely based on the results of Aksenov's research, whose activities served as the main reference point for the study of Tuvan folk music and contributed to the flourishing of Tuvan musical art in Tuva.

Villa Tugendhat as a Technical Monument - Elements of Passive Solar Architecture
Authors: Maurerová L. , Hirš J.
Published: August 2023

The elements of passive solar architecture are crucial for designing of low-energy and passive houses; moreover it might be surprising that some of the principles of passive solar architecture were applied in the functionalist Villa Tugendhat built in the year 1930, designed by the German architect Ludwig Miese van der Rohe and which belongs to the UNESCO World Heritage List.

This case study attempts to point out the individual elements of solar architecture which were applied in the villa. In order to verify some of the statements/claims a numerical simulation of incident solar radiation (XSun) was performed in the Danish simulation software BSim. The paper includes a list of other timeless technical specifics, especially in terms of HVAC, which were used in the villa, and the authors have written about elsewhere (Villa Tugendhat – An Unique Air-conditioning System in Residential Hall. CLIMA 2013. ISBN 978-80-260-4001-9).

Transforming Urban Morphology and Environmental Perfornances via IMM® The Case of PortoMaravilha in Rio de Janeiro.
Authors: Tadi M. , Manesh Vahabzadeh , Hadi Mohammad M. , Zaniol F.
Published: August 2023

IMM, Integrated Modification Methodology, is a holistic, multiscale and multi-stage, iterative process, applied to urban contexts seen as Complex Adaptive Systems, for improving their metabolism as well as their energy performances. In IMM cities are energy-using systems in their own right and they consume energy in varying level of efficiency. City as CAS is a specific type of complex system with adaptive and resilience ability and its final energy consumption and related performance is different than the sum of its heterogeneous element’s performance.

Main headline of the current paper is to focus on how urban morphology is correlated with urban sustainability and energy performance and to demonstrate how an existing urban assessment (Porto Maravilha, in Rio de Janeiro) can be reformed into a lower energy consumption system and a more liveable and sustainable context. This paper wishes to demonstrate how this design methodology can contribute through integrated design optimization to address the challenges of urban growth and environmental issues simultaneously. Actually an Urban modification theory based on an integrated approach can help to sharpen a better comprehension of the different performances of different urban assessment and contribute to climate mitigation and emission reduction, integrating Design Principles with the issue of saving natural resources. In IMM DOPs (design Ordering Principles) are tools/instruments used to arrange the structure of the CAS. The application of these principles affects the CAS’s structure and its performances. In IMM, DOP’s are associated with indicators, a core set of elements used in the process for comparing the characteristic performance of the CAS before and after the transformation occurred.

This paper using a specific and challenging case study shows that urban transformation can be performed, retrofitted and monitored with the final goal of achieving a more sustainable arrangement. The authors intended to examine how a local design area located in the dense core of Rio (Porto Maravilha) can affect transformation of the entire CAS (the city of Rio de Janeiro) towards more sustainable development of some of the city’s main concerns, mitigating marginal growth, low performances and a growing pollution as well as promoting social inclusion and a more liveable environment.
Using CFRP for Enhancing of Circular Cutout in High Strength RC Deep Beam
Authors: Alsaad Alaa , Sulaiman Abduljalil , Mohammed Jaafar A.
Published: August 2023

This paper presents the results of an experimental investigation of the using of carbon fiber reinforced polymer (CFRP) to enhance the high strength reinforced concrete (RC) deep beam in case of creating a circular cutout throughout its web. A set of 5 specimens were grouped and investigated to evaluate the structural behavior in terms of shear strength capacity and deflection. The specimens were 1200mm long with rectangular cross-section of 100x500mm. Two symmetric circular cutouts of 150mm diameter were made at midpoint of each shear span. CFRP strips were installed around the cutouts in three different configurations in order to enhance the cutout zone. The results of this experimental work showed that the diagonal configuration of CFRP strips around the cutout was the best one, as the ultimate shear strength ratio with respect to control solid beam was 0.97, while it was 0.86 for control beam with cutouts. A significant positive effect was observed on the deflection for the beams that enhanced with CFRP strips. Also, CFRP sheet oriented diagonally around cutout was the most appropriate for reducing the deflection.
Eco-Infrastructural Labs for Urban Utopias Moscow as Slow Metropolis
Authors: Carlorosi Cecilia , Pugnaloni Fausto , Filippini Gabriele
Published: August 2023

The future project of cities and highly attractive places must respond to global environmental goals, to historical and architectural heritage, and to the needs of local environments and quality of life.

Taking on that issue, this research project originates from the exchange of experiences between the Polytechnic University of the Marches (Italy), the Moscow State Forest University and the A&P Studio (Architettura&Paesaggio, Italy), who initiated the research on urban landscapes with particular reference to the sustainable regeneration in certain parts of the metropolitan area of Moscow, the saturated city at the top of the network of global cities, taken as a case study on the world level.

The trial field is the net of the “infra” spaces of Moscow, which is re-established by architecture restoring links which are broken by the infrastructure.

Infrastructure and its spaces, generally regarded as the developing drive behind the territory, in this study become the re-governing instrument of the city and opportunity for wise dialogue between the economic-financial, environmental and cultural spheres. That is possible through the project of multi-functional Hubs: they recover the marginal spaces of railway areas and tends to restore a state of dynamic equilibrium between multimodal mobility, parks and a functional mix of public services.

From the “Social Condenser” of Soviet Constructivism, the research alights on the catalysts (the new Hubs) of the collective life, which lead to the innovative use of public transport in relieving areas saturated by private transport. «Would it be possible to use the highway as a means of education?» (The view from the road, Kevin Lynch 1964). The “Moskva 7 Kholmov” idea-project replies by introjecting previous theories and more mature situations (Archigram, Yona Friedman, OMA/Rem Koolhaas) with ecological theories (Forman and Sperling).

The study suggests the overcoming of the evolutionary trauma of the metropolis in a project that reunites the senses of place and time through innovative architecture dedicated to people on the move. By skilfully balancing the infrastructural, urban, ecological and landscaping points of view, the new architecture fulfils the role of infrastructural shock absorbers, thanks to which the “Slow Metropolis” becomes a possible utopia: Moscow, urban-architectural utopia of the Twenties, becomes a positive example of the functioning of infrastructure and architecture for a mobile society.
A Digital Pre-Occupancy Architectural Toolset for Reducing Stress Levels in Urban Environments
Authors: Kalantari Saleh
Published: August 2023

This research examines the effects of the built environment on human stress and anxiety levels, by measuring the responses of participants as they interact with various architectural design features using Augmented Reality technology. Architectural form-making is becoming more dynamic and expressive in today’s world, deviating from traditional designs, especially in urban contexts. Current technology enables such forms to be created, but prior to their construction there is no easy way to determine how they might affect the stress levels of the people who experience the redesigned environment. The physical geography of cities is already known to have an effect on human well-being, and specific design issues have been correlated with negative health outcomes, including increased levels of anxiety. However, the positive or negative changes that can be induced through new designs are often just a matter of speculation. Our research helps to address this issue by developing a prototype interface to evaluate human-experience factors during the design review process. We conducted a pilot study to evaluate biometric data obtained from participants through an Augmented Reality experience, and parsed that data with respect to the participants’ personal backgrounds and other demographic information. The prototype toolset was developed based on three different architectural variables—shape, height, and visual pattern. The results from the experiment indicate there is a relationship between these architectural forms and stress levels. This research contributes to design pedagogy and practice, and it helps to show how continuous parametric form generation can be used to better reduce anxiety levels in future urban environments.
New Orders
Authors: Ottevaere Olivier
Published: August 2023

A series of alternative structures for housing are proposed through a design-research prototyping process. Nine proto-structures are developed through the conception and realization of columns cast in concrete. The series explores specific structural principles at 1to1 scale, which are further architecturally tested as speculative towers for urban living at 1to100 scale.

At 1 to 1 scale, concrete as process rather than just concrete as material sets the main methodology for the design-research. Trial and error experiments, closely related to the properties of the material (liquid to solid formation), seek to put forward new techniques of formwork design and construction procedures that are more flexible and more sustainable than past and current systems.

Design analysis, informed by the work of the early ‘structural rationalists’ (F. Candela, P.L. Nervi, H. Isler, R. Maillard, E. Dieste, et al.), considers the transformation of structural languages in an attempt to revive an architecture for vertical living (point-block).

Authors: Hengrasmee Sirimas , Chansomsak Sant
Published: August 2023

This paper is based on the research “The physical potential of a row house and town house in Phitsanulok to support a self-reliant lifestyle as guided by the Philosophy of Sufficiency Economy”. The research surveyed and studied the physical ability of row houses and town houses in urban areas. Based on the series of former researches on self-reliant of several types of existing houses, this research continues to study a mixeduse building of row house and town house. The research actually expects to get a result that shows low level of self-reliant in all basic categories. However, not only surpluses can be found from production in both energy and water for gardening, it has also proven to be able to produce enough vegetable to comfortably satisfy a family with two people on its available open areas. The findings of this research put into focus the ability of a row house and town house of being a great mixed-use building, not only for living, working, but also producing life’s essentials as well.

This study explores the various types of errors apparent in Higher Secondary level students’ writings due to which they fail to score satisfactorily in English examination. The aim of this research is to improve the writing skills of Bangladeshi secondary level learners through identification and analysis of the common errors their written corpus contains. Action research procedure (plan, act, observe, reflect and revise) has been used for this research. The answer scripts of 100 Higher Secondary level students were selected for data collection. The data was then analyzed following the traditional error analysis procedure of error identification, classification, explanation and evaluation. The result of the analysis reflects the various types of interlingual and intralingual or developmental errors learners make in their writing tasks. Based on the findings, eight teachers of those 100 students were interviewed to seek the answers to the questions as to why learners make such errors in spite of twelve years of formal education and what can be done to improve their writing skill. This research ends with some recommendations for effective teaching of the different aspects of writing.
Deconstructing the Reality: To what degree are the Ph.D. students using their computer(s) to support their research practices?
Authors: Sim KwongNui , Stein Sarah
Published: August 2023

Under normal circumstances, it is assumed that Ph.D. students will make use of ICT (e.g., computer technologies) throughout their research journey for a variety of generic and specialised purposes. Yet, there is limited documented research about postgraduate use of ICT beyond their information sourcing skills and general knowledge consumption. This paper reports the first stage of a study that aimed to examine how Ph.D. students use their computers to support their research practice, by taking into account not only their computer use skills, but also ICT use within the broader context of the research journey. Monitoring software that harvested computer activity data over a period of three months was installed on the computers of nine doctoral students from the same university who self-reported as being skilled computer users. Regular discussion sessions were held with each student to review computer activities in the light of their own research and study contexts (Ph.D. stage and discipline background). Analysis of data gathered at this first stage of the study indicates that there is no difference among the students at any stage of their doctoral research in terms of the level of their engagement with their computers, and there is no difference in the use of computer (applications and documents) among the students despite their different discipline backgrounds. At this point in the study, there is a strong indication that while ICT are playing a dominant role in doctoral student’s daily lives, ICT use to support research practice is limited. While these students used computers daily, the computers seemed not to be as crucial to their research practice as was expected. It appears that current perceptions in research literature about the importance of computer devices for student research practice may need to be questioned. This first stage of a larger study therefore provides the basis for further investigation.
Learning via Blogging: The ESL/EFL Perspective
Authors: Sattar Sanyat
Published: August 2023

The use of technology in language learning is not an unfamiliar concept. ‘Weblogs’ or ‘Blogs’ are a type of technological category that allows writing personal journals online that can be published and viewed over the web. Even though blogs are being used for personal, educational, journalistic and commercial purposes worldwide nowadays, it is not a common practice for the non-native English users. This paper shows how blogs can be an effective tool for “English as a Foreign Language”/ “English as a Second Language” (EFL/ESL) users of non-native English speakers in order to improve their English skills. It also explains how blogging not only can help in improving the basic language skills of the blog users, but also in developing their other skills like communicative and critical thinking abilities.

Authors: Miyaji Isao
Published: August 2023

In a programming course, lectures were given using a slideshow, and syntax and example programs from a textbook were explained. Afterward, students received worksheets with example programs and problems for practicing syntactic elements, and the professor explained the worksheets. The students then performed an exercise where they created a program based on example programs as an assignment. They were instructed to finish as much of their program as possible during class and to submit their program file and a report file over an e-learning site. They could learn either in class or through lecture slides uploaded to an e-learning site. Students' attitudes were assessed before and after the course. The attitudes and activities were analyzed with cluster analysis. Useful activities for improving the attitudes in a programming course were found by chi-square analysis of cross-tabulation of attitude and activity clusters. Principal component analysis of attitudes was conducted. Students were classified based on principal components of attitude scores. Characteristic of student groups is explained. The findings are reported in this paper.

Authors: Ye Liang , Wong Nai Sum , Ho Joanna Wen Ying
Published: August 2023

This paper examines students’ reflection on the design and development of a prototype biochemistry virtual laboratory (vLab) at the University of Hong Kong. Second year students from the MBBS programme were divided into two groups. One group (non-vLab) took part in the original didactic lecture while the other group (vLab) joined in the trial blended virtual lab learning session. The learning outcomes were evaluated by a post-lab knowledge comprehension quiz and the class performances were analyzed. In addition, students’ perceptions toward blended vLab learning experience were evaluated by questionnaires. The group with the vLab experience achieved higher quiz results. However, their evaluation and feedback with regard to the vLab learning experience were rather critical, which provided valuable insights for further improvements on the instructional design.

Published: August 2023

Centipedegrass (Eremochloa ophiuroides (Munro) Hack.) is commonly used as a low-maintenance warm-season turfgrass owing to its excellent adaptation to various soil types. A better understanding of the genetic diversity pattern of centipedegrass is essential for the efficient development and utilization of accessions. This study used fifty-five pairs of primers to detect the genetic variation and genetic structure of twenty-three wild centipedegrass accessions by Sequence-related amplified polymorphism (SRAP) markers. A total of 919 reliable bands were amplified, among which 606 (65.80%) were polymorphic and 160 (2.91%) were the monomorphic loci. The average polymorphic information content (PIC) value was 0.228. The unweighted pair group method with arithmetic mean (UPGMA) clustering analysis grouped the twenty-three accessions into two clusters. Meanwhile, the structure analysis showed that the tested accessions possessed two main genetic memberships (K = 2). The Mantel test significantly correlated the genetic and geographic distance matrices (r = 0.3854, p = 0.000140). Furthermore, geographical groups showed moderate genetic differentiation, and the highest intragroup genetic diversity was found in the Sichuan group (He = 0.201). Overall, the present research findings could promote the protection and collection of centipedegrass and provide comprehensive information to develop novel breeding strategies.
Characteristics of water jump for better performance in collegiate male 3000 m steeplechase
Authors: Maruo Yuya
Published: August 2023

Background

The 3000 m steeplechase consists of 28 barriers and seven water-jumping obstacles. The water jump in the 3000 m steeplechase makes it different from the sprint hurdle events. It is important for coaches and athletes to understand how to clear the water jump successfully. I aimed to investigate whether the takeoff and landing distances for the water jump per lap differ between participants with good and worse records.

Methods

Data were collected from the men’s 3000 m steeplechase races (heats) at Kanto Intercollegiate race. A total of 48 men’s performances were analyzed (24 upper group, 24 lower group). Takeoff distance, landing distance and clearance time were analyzed. Takeoff distance, landing distance, total water jump distance and clearance time were subjected to mixed two-way ANOVAs with repeated factors of Lap (lap 1/lap 2/lap 3/lap 4/lap 5/lap 6/lap 7) with Group (upper group/lower group) as a between group factor.

Results

Takeoff distance was longer for upper group (1.43 m) than lower group (1.34 m) (p = .01). Landing distance was longer for upper group (2.95 m) than for lower group (2.74 m) (p = .01) and was longer for lap 1 (2.95 m) than last three laps (lap 5: 2.83 m, lap 6: 2.82 m, lap 7: 2.76 m) (p = .01).

Discussion

Individuals who were faster in 3000 m steeplechase exhibited longer water jump distance. The effect of fatigue might be greater for landing distance than for takeoff distance. Because the landing distance becomes shorter in the second half of the 3000 m steeplechase, it is important to note that athletes should aim to land as far away from the water pit as possible.

It remains an unarguable fact that people living with HIV massively come across stigmatisation, prejudice and discrimination which kills faster than the virus itself. Thus, the fear of stigmatisation will evidently force many HIV stigmatised victims to remain silent than disclose their HIV status. The main objective of the study was to examine the influence of radio health sensitisation programme on HIV stigmatisation among residents of Owerri metropolis. The agenda setting and social learning theories served as the theoretical underpinning for the study. Survey research design was used. A sample size of 384 was derived using the Wimmer and Dominick online sample size calculator from the population of 555,500. The multi-stage cluster random sampling, involving purposive sampling techniques served as the sampling techniques with questionnaire as the instrument of data collection. The techniques required Owerri metropolis being divided into three manageable clusters. Findings of the study showed that radio health sensitisation programme on HIV stigmatisation has broadened the knowledge of the respondents on HIV stigmatisation to a high extent at a grand mean of 3.5(N=305). Also, at a grand mean of 3.4 (N=305), radio health sensitisation programme on HIV stigmatisation has influenced the behaviour of the respondents towards HIV stigmatised victims as it has induced positive behavioural changes in them. It was concluded that if there are myriads of media programmes specifically designed for mitigating HIV stigmatisation and scheduled at friendly airtimes across different media organisations, it will lead to an increased media exposure as the media constitute an effective strategy for combating HIV/AIDS-related stigma.
The Impact of U.S. Quantitative Easing (QE) Announcements on Indian Government Bond Yields
Authors: Raza Sohail , Munir Shahzad
Published: August 2023

This study investigates the impact of U.S. Quantitative Easing (QE) announcements on Indian Treasury yields. Two outstanding channels of spillover effects on bond yields documented in the existing literature are signalingchannel and portfolio balance channel. This study decomposes Indian Treasury yields into yield expectationsand risk premia to measure spillover effects of U.S. QE announcements. The impact on yield expectationmeasures signaling effect while the impact on risk premia measures portfolio balance effect. It is observed that FOMC announcements of Federal Reserve’s Quantitative Easing (QE) policy treated as shocks to Indian government bond yields. To investigate the announcement effects on Indian government Bond yields, event study methodology is used to capture the change in the bond yields, yield expectation and risk premia of Indian bond market around that time especially during the first round of Quantitative Easing (QE1) policy announcement periods in one-day and two-day window period. To support event study results regression analysis method is implemented and found robust evidence supporting larger signaling effect than the portfolio balance effect. At last, this study uses Dynamic Nelson-Siegel (DNS) yield curve model to compute the relationship between the U.S. and Indian Bond market. DNS model involves two-step estimation using VAR regression on Indian government bond yields with U.S. 10-year Treasury yield changes as an exogenous variable. The statistical result of DNS estimation shows that U.S. 10-year Treasury yield change affects the Indian long-term bond yield during the financial crisis period.

Authors: Anggarani Ni Kadek Nova , Suryatika Ida Bagus Made , Sutapa Gusti Ngurah
Published: August 2023

Aims: Slice thickness variation analysis on spatial resolution on CT-scan images by determining CNR and SNR values, by making ROI on object and background images. ROI size of objects and backgrounds can be observed with several criteria based on the provisions of the ACR program, so that optimization of CT-Scan image quality can be achieved.

Place and Duration of Study: The Radiology Installation in Bali Mandara Hospital, between 23 March to 20 May 2022.

Methodology: Data collection begins with preparing the equipment used, namely CT-Scan, head holder, phantom, and computer. After that, the head holder is placed in the middle of the gantry and then the phantom is placed with the guidance of the laser beam (alignment system). Set the axial beam on the vertical line of section 1 and then set the coronal beam on the horizontal line of section 2. After that, setting the type of examination using the adult head protocol and setting the scan parameters to 80 kV, 100 mAs, and slice thicknesses 1, 2, 3, 4, 6, and 8 mm. After the preparation is done then the next exposure to the phantom. Then the research data in the form of phantom images will be seen as a whole to program on the computer monitor. Measurements were made 5 times for each slice thickness. Next is to analyze the CNR of digital phantom image data on a computer. So that it can be determined object ROI, background ROI, object mean, background mean, and standard deviation of the background.

Results: The results showed that the thicker the Slice Thickness, the higher the CNR and SNR values. The highest CNR value occurred in air medium (13.70) and the lowest occurred in Nylon (0.86). Likewise, the highest SNR value occurred in air medium (13.84) and the lowest in Nylon (0.99). The highest CNR and SNR values ​​occurred in air medium and the lowest occurred in Nylon.               

Conclusion: Slice Thickness variations affect the spatial resolution of CT-Scan images as indicated by the CNR and SNR values however, the CNR and SNR values ​​are still above 1.0 for adult head examination and above 0.7 for children's head examination. So that the quality of CT-Scan images at Bali Mandara Hospital is still very good.

Published: August 2023

The development of earth-based bio-sourced materials requires a thorough analysis of the study soil. For the present study, we took five (05) soil samples from a tunnel-digged quarry in the layer between 0.5 m and 5 m : white clay (MSB-BL), red clay (MSB-RG), weak clay or sandy clay (MSB-FB), strong clay (MSB-FR) and mixture (MSB-ME). To verify the quality of these five (05) soils samples, their intrinsic properties were determined at the National Building and Public Works Laboratory (LNBTP). These included grain size, clay content, specific weight, loss on ignition and moisture content. These analyses revealed that MSG-RG and MSG-BL clays have fine fractions of 64.28% and 47.85% respectively; clay fractions of 27.51% and 20.61% respectively; and methylene blue values in the range (6;8). Their plasticity indices are in the range (20;40). These two (02) clays thus meet the requirements in terms of granularity, and their relatively high clay fraction will favor their adhesion with admixtures such as plant fibers. What's more, the particle size distribution of these clays is within the ideal CRAterre range for soils used in the manufacture of BTC or adobes, so they are all eligible.

Changes in lifecycle forms of tree species seriously affect their production leading to global warming which has a lot of influence on peoples’ economic status through the provision of ecosystem services. It is important to study the lifecycle changes occurring in tree species and their diversity as a result of global warming since a lot of tree species serves as food to wild animals their absence means animals which depend on them for food will starve to death or migrate thereby affecting conservation activities as well as the wellbeing of people who depends on the park and conservation projects operating within the park for a means of livelihood.

An aspect of Tree species Phenology and Diversity for Conservation in Chimpanzee Forest Habitat at Kwano, Gashaka Gumti National Park, Nigeria was conducted with the view to examine the phenology and diversity of tree species in the forest for better conservation strategy. An 8km transect with tagged trees was monitored on foot for phenological activities of leafing, flowering, fruiting and leaf shedding for 3 months. Shannon-Wiener’s Diversity Index (SWDI) was used to determine tree species diversity. ANOVA was used to compare the phenological data among the months of study. SWDI was 4.115. A total of 867 individual tree species consisting of 127 species from 45 families and with 4 unidentified tree species found on this transect indicated that Anogeissus leiocarpus (7.04%) is the highest in the number of the tree species, Trichilia martineani (6.34%) and Crossopteryx febrifuga (5.65%). Euphorbiaceae family (17.42%) was the highest among the diverse tree species observed in Kwano forest followed by Combretaceae (9.80%) and third by Caesalpinoideae (8.65%). Cappar idaceae, Lecythidaceae, Calophyllaceae, Melianthaceae, Celtidaceae, Celastraceae, Ma esaceae, Burseraceae, Rutaceae, and Dracaeroaceae each with 0.12% were the least family es observed. Only 0.12% tree species was observed leafing, 3.92%, 2.19% and 1.73% flowering I                                    n June, July and August respectively while 3.92%, 7.27% and 7.96% were fruiting in June, July and August respectively, none was observed shedding leaves. Comparison of the phenological data reveals significant differences in fruiting and flowering (P < 0.05), none in leafing and leaf shedding (P >0.05). Understanding the phenology and tree species diversity of this forest could enhance better conservation strategies. More phenological studies are recommended in the Park.

The present investigation was undertaken to estimate the genetic variability, heritability and genetic advance for growth and yield parameters among 37 genotypes of betel vine in a randomized design with 3 replications during 2019-21 at farmer’s field, Badami, Karnataka. Analysis of variance revealed that the genotypes significantly differed for all the characters studied. The results showed that phenotypic coefficient of variations values were higher than the genotypic coefficient of variation for all the characters studied. The values of heritability in broad sense were observed very high for all the twenty one traits. Correlation studies revealed that total yield per vine was significantly and positively correlated with plant height (0.918), number of laterals per vine (0.988), number of leaves per lateral (0.827), total number of leaves per vine (0.863), clinging roots (0.887), petiole length (0.814) and path analysis showed that the traits such as number of laterals per vine (0.6350), total number of leaves per vine (0.2601), clinging roots (0.0839), leaf area (0.2091) and petiole length (0.2696) had direct and positive effect on total yield per vine. Hence, direct selection would be more effective in improving these traits. In this background, the aim of the study is to identify considerable variations among the genotypes for further crop improvement programme and multiplication of quality planting material.

Authors: Choudhary Aanchal , Daniel Sameer
Published: August 2023

An experiment was carried out to assess the allelopathic effect of leaf leaches of Morus alba on the growth and yield of Brinjal. Leaf leaches were prepared by soaking sun dry leaves in tap water for 24 Hours in a ratio of 1:10 (w/v). Various concentrations of leaf leashes (25, 50, 75 and 100%) were prepared. The result showed that the concentration plays an important inhibitory role on germination, shoot and root growth of brinjal. During laboratory experiment, seeds were soaked in  different concentrations and germination percentage, root and shoot length were observed. After laboratory experiment it was noticed that that the seed soaked in 25% concentration of Morus alba leaf lashes has better results than higher concentrations. In pot culture experiment, control have good effects on growth and yield of brinjal as compared to different concentration. Lower concentrations (25 and 50%) have beneficial effects on growth and the yield as compared to the higher concentrations (75 and 100%). At lower concentrations of Morus alba leaf leachates, the survival percentage of crops were more as compared to the 100% concentration. It can be concluded that the harmful effect of Morus alba was less on brinjal and recommended to avoid its use in the early growth stages of the crops.

Land use describes the actual form of land, such as a forest or open water and classification based on human utilization. Land use map provides the information about the current landscape of an area. In this study, the Lower Bhavani basin's land use and land cover were classified using GIS platforms and data from the Landsat 8 satellite. The platform utilized in this study were Semi-Automated Plugin (SAP) in QGIS and Random forest method in Google Earth Engine (GEE). The findings suggested that both platforms performed efficiently and displayed comparable percentages of land covered by various land use features. The accuracy of the resulting land use map was evaluated using a Google Earth image, and it was discovered that SAP and GEE hold 91.8% and 92.6% of the total accuracy. This study aids in evaluating and classifying the various Geographic Information System platforms land use trends.

Background: The extensive use of chemical fertilizers to boost vegetable production has been acknowledged, but its long-term consequences on soil health, ecology and other natural resources are detrimental. These effects extend to beneficial soil microorganisms and human beings. Therefore, there is a need of organic resources for plant nutrition.

Methodology: An experiment was carried out during rabi season, 2020 at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat. It was laid out in randomized block design with factorial concept with three replications comprised of two factors viz., different organic manures with six level i.e., 80% RDN through FYM (o1), 80% RDN through Poultry manure (o2), 80% RDN through Vermicompost (o3), 60% RDN through FYM (o4), 60% RDN through Poultry manure (o5) & 60% RDN through Vermicompost (o6) and bio-enhancer with two level i.e., NPK consortium @ 5 lit/ha (f1) and Ghan-Jeevamrut @ 250 kg/ha (f2).

Results: Among different application of organic manures, 80% RDN through Vermicompost performed significantly superior over other treatment with respect to TSS (7.07 oBrix), chlorophyll a (62.31 mg/100g), chlorophyll b (24.78 mg/100g), total chlorophyll content (87.09 mg/100g), available N (236.16 kg/ha), P (36.12 kg/ha) and K (361.07 kg/ha) in soil, N uptake (67.90 kg/ha), P uptake (8.46 kg/ha) and K uptake (61.74 kg/ha) by plant. Among different bio-enhancer, NPK consortium @ 5 lit/ha was found significantly superior with respect to chlorophyll b (24.00 mg/100g), total chlorophyll (83.10 mg/100g), organic carbon (0.36%) in soil, N uptake (63.61 kg/ha), P uptake (7.79 kg/ha) and K uptake (59.60 kg/ha) by plant. However, the interaction effect of both organic manures and bio-enhancer has found non-significant in terms of quality, soil attributes and nutrient uptake.

A field experiment entitled “Effect of weed management practices on growth, yield and productivity of wheat (Triticum aestivum L.)’’ was conducted at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (Uttar Pradesh) during Rabi season 2018-2019. The experiment was laid out in randomized block design with three replications. There were twelve treatments of weed management practices, namely: T1 - Sulphosulfuron 25g a.i. ha-1; T2 - Metsulfuron 4g a.i. ha-1; T3 - Clodinofop 60g a.i. ha-1; T4 - Metribuzin 210g a.i. ha-1; T5 - Sulphosulfuron+Metsulfuron (30+2) 32 g a.i. ha-1; T6 - Sulphosulfuron+Metribuzin (25+210) 235 g a.i. ha-1;  T7 - Clodinofop+ Metsulfuron (60+4) 64 g a.i. ha-1; T8 - Fenoxaprop–p–ethyl 120 g a.i. ha-1; T9 - Fenoxaprop-p-ethyl + Metsulfuron (120+4) 124 g a.i. ha-1; T10 - Two hand weeding at 20, 40 DAS; T11 -  Weedy check; T12 - Weed free. From the results, all the growth parameters (or yield attributes) like;  higher number of spike (m-2), Length of  Spike (cm), number of spikelet Spike-1, Grain per ear head (m-2),  and Test Weight (g) plus yields of  grain and straw, as well as higher harvest index of wheat obtained were significantly higher under weed free treatment of 52.50 qha-1 followed by under T7 - Clodinofop+ Metsulfuron @ (60+4) 64 g a.i. ha-1 at an obtained yield of wheat is 51.10 qha-1. The highest net return (81054.50 Rs. ha-1) and benefit cost ratio (2.04) was recorded under T7 - Clodinofop + Metsulfuron @ (60+4) 64 g a.i. ha-1. Thus it may be recommended for effective control of weeds and higher production of grain and straw yield in wheat crops.
