Authors: Nguyen Thao Ngoc , Stewart Chris , Matousek Roman
Published: September 2018

The purpose of this paper is to examine risk management of the Vietnamese banking system. This is the first such study of the Vietnamese banking system. To be able to carry out a comparative analysis and provide policy recommendations for risk management, we carry out an original survey of Vietnamese commercial banks using a questionnaire. 42% of the interviewees are General/Deputy General Directors and 58% are Heads/Deputies of a risk management department. The Kruskal-Wallis, Pearson chi-square and other tests are employed to examine the relationship between risk management and bank efficiency. The survey results indicate that there is a difference between banks in terms of risk area identification, risk intensification methods prioritized, risk monitoring methods, efficiency improvement suggestions, awareness of other banks’ risk management systems and credit risk analysis.

Published: September 2018

Stillage is a main by-product of the bioethanol industry and, depending on the origin of substrates for bioethanol production, it can be a significant pollutant affecting the profitability of bioethanol production. Directing the stillage towards the production of bio-based chemicals or high-quality feed is a preferred strategy. In this paper, a complete utilization of stillages of different origins was assessed. Thin stillages from bioethanol production from molasses, wasted bread and corn were chemically characterized, evaluated and compared as substrates for lactic acid (LA) and probiotic biomass production by Lactobacillus rhamnosus ATCC 7469, while solid fractions of wasted bread and corn stillages were analyzed for feed. The impact of pH control using CaCO3 or NaOH was also examined, both in terms of LA production and valorization of the remains generated in each process.A maximal LA productivity of 1.14 g/(L h) was obtained on thin wasted bread stillage with pH control by NaOH while the number of viable probiotic bacterial cells was above 109 CFU/mL. The composition of the solid fraction of the wasted bread stillage was complementary with the needs of monogastric animals, while the solid fraction of corn stillage was more adequate for the nutritional requirements of ruminants.
The musical Mach-Zehnder interferometer
Authors: Garner Andrew
Published: September 2018

The phenomenon of interference lies at the heart of quantum physics, and is
responsible for many of the unusual aspects of quantum behaviour that
deviate from our everyday expectations. Though classical physics allows for
waves (e.g. of sound) to interfere, quantum theory allows for interference
effects also to affect single particles. One device that demonstrates this
experimentally is the Mach-Zehnder interferometer: here a single particle
(e.g. a photon) travels down one of two possible paths, and quantum
interference between the two paths affects the final position where the
particle arrives. In this article, I propose a mechanism to musically
demonstrate quantum single-particle interference: the musical Mach-Zehnder
interferometer. This new quantum musical instrument makes use of two
independently operated electronic keyboards, whose outputs are interfered
according to the rules of the Mach-Zehnder interferometer. I discuss the
musical possibilities this instrument enables, and outline a method to
construct it via software simulation.
What does quantum music sound like and what would Pierre Boulez think of it? Super position (many worlds) by Kim Helweg (2017)
Authors: Medic Ivana , Jankovic-Begus Jelena
Published: September 2018

Pierre Boulez (1925-2016) devoted a great deal of time and consideration to
the relationship between the composer?s invention and performance media, in
particular those related to the application of the latest technological
breakthroughs and new instruments. Boulez?s famous essay ?Technology and the
Composer? (1977/1986) proclaims his desire to widen the range of expressive
means of art music by conquering new media. Boulez?s ?vintage? insights are
here juxtaposed with a contemporary Quantum Music project (2015-2018), and
with one particular piece written within this project: Super Position (Many
Worlds) by Kim Helweg (2017), commissioned by the Institute of Musicology
SASA and supported by the Danish Arts Foundation (Statens Kunstfond). At
least two lines of thinking relevant for the present discussion can be drawn
from Boulez?s text: the first dealing with the possible development of new
musical instruments, and the other inviting a merger between music
composition and science.
Cognitive and metacognitive strategies as predictors of language learning outcomes
Authors: Saks Katrin , Leijen Äli
Published: September 2018

Inconsistent findings in earlier research on language learning strategies and their relations with language proficiency motivated this deeper exploration of the effects language learning strategies have on learning outcomes. The aim of the study was to explore the potential effects of cognitive and metacognitive language learning strategies on learning outcomes. The investigation involved self-reported data from a sample of 269 final-year students of upper-secondary schools (aged 18.4) analysed with the results of the standardized English as a foreign language exam. The analysis revealed a linear relationship between language learning strategies and learning outcomes based on learners? perceptions. Structural equation modelling indicated that cognitive strategies have a direct effect on learning outcomes, whereas metacognitive strategies affect outcomes indirectly.
The role of self-control, self-efficacy, metacognition, and motivation in predicting school achievement
Authors: Dzinovic Vladimir , Djevic Rajka , Djeric Ivana
Published: September 2018

Self-control and self-regulated learning refer to those processes and strategies whereby individuals exert agency in facing educational demands. This study tested a structural model which predicts that self-control has direct effect on school achievement, as well as mediated by metacognitive self-regulation, academic self-efficacy, and regulatory motivational styles as the variables related to self-regulated learning. The research was carried out on a stratified random sample of 575 eighth grade students. It was shown that the effect of self-control on achievement is mediated by self-efficacy. In other words, students who have heightened selfcontrol and believe in their own ability to meet school demands will be successful in school regardless of the complexity of their learning or whether they are autonomously motivated. The implications of such a finding were considered, as well as the limitations of the research and the indications for future research.
Experimental and numerical analysis of flow field and ventilation performance in a traffic tunnel ventilated by axial fans
Authors: Sekularac Milan , Jankovic Novica
Published: September 2018

To investigate air flow in longitudinally ventilated traffic tunnels, a scaled model of a typical road-traffic tunnel with an appropriate ventilation system based on axial ducted fans, is designed and built in the Lab. The focus of this paper is the airflow in a bi-directional traffic, two-lane tunnel. At the scale ratio of approx. 1:20, at 20.52m length it represents ? 400m of a realscale tunnel. The model consists of two parallel tunnel tubes, where the main tunnel (with a hydraulic diameter of ???1 ? 0.4m) has the geometry of a scaled road traffic-tunnel. The second tunnel (???2 ? 0.16m) has a smaller size and is circular in cross-section, used only to simulate airflow towards an evacuation tunnel tube. Thus the two tunnels are connected by the evacuation passages, equipped with adjustable escape doors. By a combination of experimental and numerical work, the air flow-field and the performance of the ventilation system are investigated. The velocity field and its turbulence properties exiting the fans were determined experimentally using hot-wire anemometry. These data were further processed to be used in the tunnel flow computations by CFD. The efficiency of momentum transfer (????, Kempf factor) of the longitudinal tunnel ventilation is determined. The effect that the imposed boundary conditions and the level of their detail, have within a CFD computation of tunnel airflow, with respect to accuracy, velocity distribution and computed ????. Finally a traffic-loaded (traffic ?jam?) case of flow is studied through experiment and CFD. The difficulty in assessing the required thrust of the plant in traffic-jam tunnel conditions is discussed, and the ventilation efficiency is estimated. Based on later results, the two limiting shapes of axial velocity distribution with respect to height above the road, in this type of tunnel and traffic, are estimated. The last result can be used as a realistic boundary condition (as inlet b.c. and/or initial condition) for numerical studies of flow and fire scenarios in such tunnels with the traffic load critical for design.
Effect of spherical blockage configurations on film cooling
Authors: Wang Jin , Tian Ke , Zhang Kai , Baleta Jakov , Sunden Bengt
Published: September 2018

With increasing inlet temperature of gas turbines, turbine blades need to be effectively protected by using cooling technologies. However, the deposition from the fuel impurities and dust particles in the air is often found inside film holes, which results in partial hole blockage. In this paper, the deposition geometry is simplified as a rectangular channel, and the effect of three blockage ratios is investigated by using the computational fluid dynamics. In addition, water droplets are also released from the coolant inlet to provide a comparison of the results with and without mist injection. It is found that the lateral film cooling effectiveness is reduced with increasing blockage ratio. For all the cases with the blowing ratio 0.6, 1% mist injection provides an improvement of the cooling performance by approximately 10%.
Numerical study of hydrodynamics and thermal characteristics of heat exchangers with delta winglets
Authors: Wang Yu
Published: September 2018

The comprehensive performance of heat exchangers is represented by the maximum thermal transfer, the minimum pressure loss, and the smallest pumping power. In recent years, the application of longitudinal vortex generators is developed as an effective technique and important research topic, which could increase the heat transfer enhancement of compact heat exchangers. A 3-D CFD numerical simulation is successfully carried out on thermohydraulic characteristics of the fin-and-tube compact heat exchanger with new types of vortex generators. The effects of six different arrangement of delta winglets are studied, which are front-up-rear-down, front-down-rear-up, common-flow-up, and common-flow-down. In addition, there are also different direction of hole position in the same delta winglets arrangement. The investigation of thermal-hydraulic performance is conducted for Reynolds number in the range of 204-2034. The overall and local performance comparisons among the fin with delta winglets and the wavy fin are performed. Then, the comprehensive performance evaluation diagram was adopted to analyze the combined index point of thermal and flow. This study shows that the flow distinction between different fins has a profound influence on the thermal-hydrodynamic performance. The results reveal that the fin with delta winglets can considerably strengthen the thermal efficiency with a moderate pressure loss penalty. The computational results indicate that the average j-factor for the fin with delta wing-lets can be increased up to 41.9% over the baseline case and the corresponding f-factor decreased up to 19.5%. The combination property of front-up-rear-down are better the others at lower Reynolds number, and that of front-down-rear-up are better at higher Reynolds number. Compare with the traditional arrangement (common-flow-up and common-flow-down), The newly designed fin has great effectiveness and uniform performance in the local region.
A coupled flow and chemical reactor network model for predicting gas turbine combustor performance
Authors: Hataysal Seyfettin , Yozgatligil Ahmet
Published: September 2018

Gas turbine combustor performance was explored by utilizing a 1-D flow network model. To obtain the preliminary performance of combustion chamber, three different flow network solvers were coupled with a chemical reactor network scheme. These flow solvers were developed via simplified, segregated and direct solutions of the nodal equations. Flow models were utilized to predict the flow field, pressure, density and temperature distribution inside the chamber network. The network model followed a segregated flow and chemical network scheme, and could supply information about the pressure drop, nodal pressure, average temperature, species distribution, and flow split. For the verification of the model?s results, analyses were performed using CFD on a seven-stage annular test combustor from TUSAS Engine Industries, and the results were then compared with actual performance tests of the combustor. The results showed that the preliminary performance predictor code accurately estimated the flow distribution. Pressure distribution was also consistent with the CFD results, but with varying levels of conformity. The same was true for the average temperature predictions of the inner combustor at the dilution and exit zones. However, the reactor network predicted higher elemental temperatures at the entry zones.

Published: September 2018

Forest fires that occurred in Portugal on June 18, 2017, caused several tens of human casualties. The cause of their emergence, as well as many others that occurred in western Europe at the same time remained unknown. Taking into account consequences, including loss of human lives and endangerment of ecosystem sustainability, discovering of the forest fires causes is the very significant question. The heliocentric hypothesis has indirectly been tested, according to which charged particles are a possible cause of forest fires. We must point out that it was not possible to verify whether in this specific case the particles by reaching the ground and burning the plant mass create the initial phase of the formation of the flame. Therefore, we have tried to determine whether during the critical period, i. e. from June 15-19 there is a certain statistical connection between certain parameters of the solar wind and meteorological elements. Based on the hourly values of the charged particles flow, a correlation analysis was performed with hourly values of individual meteorological elements including time lag at Monte Real station. The application of the Adaptive Neuro Fuzzy Inference System models has shown that there is a high degree of connection between the flow of protons and the analyzed meteorological elements in Portugal. However, further verification of this hypothesis requires further laboratory testing.

Authors: Milicevic Sasa , Jevtic Aleksandar , Stepic Nenad
Published: September 2018

Background/Aim. Planning an elliptical excision of the facial skin, caused by lines of minimum tension, is very important in order to achieve good aesthetic results. The width of the tumor excision affects the possibility of a direct closure of the post-excision defect. The aim of the study was to determine the minimum width of excision that does not affect postoperative symmetry of the face, in relation to the preoperative one, using an objective scanning method with a line laser scanner. Methods. The study included 50 patients of both sexes, older than 50 years, who had verified facial skin tumor and established medical indication for surgical elliptical excision and direct suture. All patients had laser scanning preoperatively, and then seven days and 90 days postoperatively, giving x, y, and z coordinates of 5 cephalometric points on the face, which determined the shape of the examined region. Patients were divided into three groups depending on the width of the excision (< 10 mm, 10?15 mm, > 15 mm). The shape of the examined region among different width of excision was compared, preoperatively, 7 days and 90 days postoperatively, using Procrustes analysis and analysis of the coordinates of cephalometric points. Results. Taking into account preoperative and postoperative x, y and z coordinates of the cephalometric points, statistically significant differences between the group of patients with the width excision < 10 mm and the other two groups (excision width 10?15 mm and > 15 mm) were found. Conclusion. The width of the skin tumors excision < 10 mm does not affect the postoperative facial asymmetry when a post-excisional defect is closed by direct suture.
The Importance of Role-Specific Performance and Sociopolitical Factors for Chief Financial Officer Employment Outcomes
Authors: Engel Ellen , Gao Feng , Wang Xue
Published: September 2018

SYNOPSIS

This paper investigates the importance of role-specific performance measures and sociopolitical factors in the career paths of CFOs. We find that forced CFO turnover is associated with poor performance in functions over which they have more direct influence, including financial reporting, financing, and regulatory compliance. We also find that CFOs are less likely to be dismissed when they have greater connectedness with the CEO and have stronger influence within the firm. Interestingly, sociopolitical factors are linked with promotion outcomes, but economic performance does not appear to play a significant role. The collective evidence indicates that both economic and sociopolitical factors have an important role in influencing CFO career paths.
Building Information Modelling Uptake: Tool Training in Nigeria
Authors: Hamma-adama Mansur , Kouider Tahar , Salman Huda
Published: September 2018

Computer Aided Design software and their kind are generally considered as Building Information Modelling (BIM) tools; moreover the sophistication level of one determines its maturity level. Education and research are the background to innovation while training is a window to continuity in skills transfer. The BIM uptake in the developing countries is significantly lagging behind; amongst various reasons is the lack of trained professionals. Experts are evolving from the industry professionals who are first trained in the university. This study determined the capacity of Nigerian universities in providing BIM tools training for BIM adoption in Architecture, Engineering and Construction (AEC). The study is quantitative in nature, with the primary data collected through a structured questionnaire survey within the built environment and engineering schools of Nigerian universities. The collected data were analysed using descriptive statistics. The institutions are physically ready with relatively sufficient hardware, however technically not ready due to insufficiency of up to date software. There is a significant correlation between software availability and proficiency level of training, while no correlation between academic qualification and the training proficiency. More than 70% of the students are graduating on ‘file based collaboration’ – 2D and 3D CAD knowledge with proficiency level between limited and practical application. However, the collaborative software training received proficiency level of basic to practical application; a 13% trained on collaboration software is very little to providing experts for the industry. This reveals a clear setback in the tools training to carter for the BIM uptake in the country.

Published: September 2018

Most ofnewborns with Congenital Heart Defects (CHDs) can be detected by using echocardiography. However, if such defects are not diagnosed in earlier time, therefore a severe hypoxemia, shock, acidosis and death are considered of some potential sequelae. A prospective study from January 2012 to the end of 2013 was performed and 2181 neonates were enrolled in the study. The pulse oximetry screening (POS) for both hands and one foot were obtained within the first 3-6 hours of life, when post ductal saturation was below 90%, it was considered as a positive screening, while when the saturation is between 90-95% and the difference between pre-and post-ductal saturation was more than 3%, the baby was provisionally considered to be screening as a positive then echocardiography is planned. Among 100 positive POS babies, 45 (45%) of them were detected with CHS, 12 (12%) was with a major CHS and 33 (33%) was with a minor CHS. Out of 12 patients with a major CHD 6 of them (50%) were asymptomatic at the time of POS.POS result was a true negative in 2078 patients, a true positive in 45 patients, false negative in 3 patients, and false positive in 55 and 28/55 of the false positive rate with POS had other pathology. The false positive rate with pulse oximetry screening is (55/2081) = 0.26%. Sensitivity, specificity, positive and negative predictive value for POS in detection of major CHD were 80%, 97.29%, 17.9% and 99.80%, respectively. Pulse oximetry screening is significantly improving the detection of life threatening congenital heart disease at an early stage.

Introduction. According to WHO data, COPD is the 4th cause of death in the world. The important problems of COPD are frequent exacerbations, comorbid conditions and late diagnosis. One of the most important factors in the formation of COPD is smoking. Recently, special attention is paid to the peculiarities of the course of COPD in women.

The objective of this study was to reveal the peculiarities of smoking status in people of different sexes with different severity of respiratory symptoms in order to further creating the groups of patients on tobacco cessation.

Material and methods. 108 smoking patients aged 20 to 60 years were examined in real outpatient practice. Besides the questionnaire, all examined underwent spirometry and CO determination (ppm) in exhaled air.

Results. Analysis of the results of the study showed that women started smoking later than men. The number of day-today smoked cigarettes, the smoking index, and the degree of nicotine addiction in women were significantly less that was naturally accompanied by a significantly lower content of CO in the exhaled air. Broncho obstructive syndrome was found in 56% of men and 44% of women; the degree of nicotine addiction and respiratory symptoms were interrelated only in women (r=0.50, p<0.01). The period of withdrawal from tobacco smoking was significantly longer in women despite of the almost equal motivation to smoking cessation and the number of attempts of getting rid of tobacco addiction.

Conclusions. Significant gender peculiarities of smoking status the degree of motivation to smoking cessation, their relationship with respiratory symptoms were revealed which requires the introduction of different approaches to the programs of healthy lifestyle in people of different sexes.

Published: September 2018

Two models of Artificial Neural Network (ANN) algorithm have been developed for monthly rainfall prediction, namely the Backpropagation Neural Network (BPNN) and Radial Basis Function Neural Network (RBFNN). A total data of 238 months (1994-2013) was used as the input data, in which 190 data were used as training data and 48 data used as testing data. Rainfall data has been tested using architecture BPNN with various learning rates. In addition, the rainfall data has been tested using the RBFNN architecture with maximum number of neurons K = 200, and various error goals. Statistical analysis has been conducted to calculate R, MSE, MBE, and MAE to verify the result. The study showed that RBFNN architecture with error goal of 0.001 gives the best result with a value of MSE = 0.00072 and R = 0.98 for the learning process, and MSE = 0.00092 and R = 0.86 for the testing process. Thus, the RBFNN can be set as the best model for monthly rainfall prediction.

Authors: Kuzmina T. G. , Nikashina V. A. , Romashova T. V.
Published: September 2018

Kinetics of Sr2+sorption from potable water on clinoptilolite tuffs (CLPT) of different deposits (Honguruu (Yakutia), Holinskoe (Transbaikalia) and white Plast (Bulgaria)) is studied in detail. A technique of X-ray fluorescence analysis (XRF) is developed to determine the chemical composition of CLPT from a small sample (0.05 – 0.1 g). The emitters are prepared by pressing 10-mm tablets from the initial material added with polystyrene as a binder in a weight ratio 5:1. Reference standards (reference standards of composition) of rocks close in chemical composition to the CLPT are used for calibration. Using the empirical model of α-correction, the equations are derived to calculate the content of macro components of the sample in the «saturated» layers. To calculate the strontium content in the «intermediate» layers for the CLPT from different deposits the correction equations are derived. It is shown that the correction equation can be the same for all the CLPT used in the experiment. Kinetics of Sr2+sorption on CLPT consists of 3 stages: (a) the intra-diffusion process, described by the coefficient of internal diffusion, (b) deceleration of the sorption process, described by the corresponding kinetic coefficient, and c) secondary increase in Sr2+sorption which terminates when the equilibrium is reached. The results can be used to develop a mathematical model describing the dynamics of the ion-exchange process on CLPT in NH4form from dilute solutions.

Published: September 2018

The social value of Computer Studies as a subject, which teaching should contribute to solving the problem of successful targeting of professional self-determination of schoolchildren on the most urgent in society, the specialty of IT industry, is extremely high. Therefore, an integral part of the professional training of future teachers of informatics in higher educational institutions should be their preparation for the career guidance of pupils on the IT specialty. Based on the results of scientific and pedagogical research of scientists, one can single out general principles of the same preparation. Such principles reflect the current general-didactic approaches to the methodology of the training of future teachers of informatics and have somewhat consistent content. The general principles include consistency, continuity and regularity; scientific and actuality (knowledge and professional skills); systematic; connection theory with practice; the unity of scientific and educational work; consciousness, activity and self-determination of students. At the same time, developed in the writings of scientists, psychological and pedagogical principles of training future teachers to work with career guidance of pupils are extremely generic meaning and direction, do not address the specifics of specific professional areas of vocational guidance, trends of modern development. The purpose of the article is to justify the content of specific principles of preparing future teachers of informatics to career guidance of pupils on IT-specialty. The special principles of the preparation of future teachers of informatics to the career guidance of pupils on IT-specialty reflect as the features of the school subject «Computer Studies» in terms of career guidance, as a specificity of the IT-industry as a sphere of professional orientation. In our opinion, such can include the principles: axiological orientation, integration, prognostics, innovation, and reliance on the own practical experience. Principles of preparation are guidelines for determining the content, means, forms, methods of organizing such training. The above principles should be placed on the basis of constructing a model for the preparation of future teachers of informatics for career guidance work with pupils on the ITspecialty in the system of higher pedagogical education.

Considering the fact that wind turbines operate at the bottom of the atmospheric boundary layer (ABL) where the turbulence is at a high level, and the difficulty of mesh generation in the fully modeled numerical simulation, it is necessary to carry out researches to study the wake flow of wind turbines with consideration of the inflow turbulence. Therefore, a numerical method generating turbulence was proposed and the results show good agreement with those in experiments, based on which the flow fields in the wake of a wind turbine at two tip speed ratios are examined in detail through three actuator methods, namely, ADM, ADM-R and ALM. The performances of these methods were studied and the error sources for each method are clarified. Moreover, the computational efficiency were revealed and the influencing factor for the efficiency is concluded. Besides, the equilibrium relation of the N-S equation in the wake is revealed, which provides a theoretical basis for the optimal arrangement of the wind turbine. It shows that the mean velocity and fluctuating velocity vary greatly near the wind turbine, and become stable gradually away from the wind turbine. The results of ALM method shows the best agreement with the experiment. At near wake region, the turbulent stress term, pressure gradient term and convection term mainly contribute to the equation equilibrium, and convection term is in equilibrium with the turbulent stress term at the far wake.

This study aims to investigate the individual or retail investors investment behavior to know that individual demographics and financial factors such as gender, age, educational status, income, and investment levels determine their investment trading behavior amongst three domains namely fundamental, market events and personal factors. We have found that demographic characteristic such as marital status does not play any significant role in determining their investment trading behavior. The structured survey is used to collect data through a personal administration of individual investors belonging to PSX and brokerage firm. Further we use ANOVA and multiple regression to analyze the data collected from primary methods. The evidence suggests that retail investors’ self-confidence is function of both expected and unexpected changes in the market and personal factors which shape the retail investors trading behaviors. The self-confidence and portfolio size are positively related which means that over confident individual investors believe that they have great knowledge and skills. This relationship would help them to perform better than others as over confidence leads them to hold big portfolios

Adsorption process is one of the best ways for removal of dyes from effluent generated from different industries. The use of adsorbent manufactured from sugarcane bagasse as well as bamboo fibre bundles, an agro squander from sugar and building industries have been reviewed as an excellent replacement for stimulated carbon sorbents for the removal of dyes from wastewater. Agricultural based adsorbents prepared from sugarcane bagasse and bamboo may be successfully used to remove the unused hydrolyzed dyes from an effluent of textile dyeing industry. These ready adsorbents may very much capable in decolorization of the textile effluent. In this review, literature of two sorbents has been compiled. The review assesses these agricultural based materials as low-cost adsorbents for the removal of hydrolysed dyes from textile effluent. The review also draws some of the basic mechanism of dye adsorption on to.

An experiment was conducted to assess the impact of flucetosulfuron, a new generation sulfonylurea herbicide, on weed seed bank dynamics of wet land paddy field. Field experiments were carried out during two consecutive seasons (Kharif 2016 and Rabi 2016-’17), to assess the bio-efficacy of flucetosulfuron in wet seeded rice which was accompanied by weed seed bank assay. Weed seed bank assay of the soil was carried out before and after the field experiments in both the seasons by the seedling emergence method. The experiment on weed seed bank was laid out in Completely Randomised Block Design (CRD) with 12 treatments replicated thrice. Flucetosulfuron @ 20, 25, and 30 g ha-1applied at 2-3, 10-12, and 18-20 days after sowing (DAS) along with two control treatments viz., hand weeding at 20 and 40 DAS and unweeded control comprised the treatments. The emerging weeds were uprooted at 14 days interval up to a period of two months; categorized as grasses, broad leaved weeds, and sedges and counted. Results revealed that non-herbicidal plots recorded significantly higher count of total emerged weeds compared to herbicide applied plots. In all the herbicide applied plots, effective reduction in weed seed bank could be obtained irrespective of the dose of the herbicide. Regarding the time of application, flucetosulfuron applied at 10-12 and 18-20 DAS recorded significantly lower weed seed bank during both the seasons, compared to its application at 2-3 DAS.

The experiment was conducted at Coconut Research Station, Balaramapuram with an objective to study the effect of nutrient levels and nutrient schedules on physiological parameters and grain yield of upland rice (MO 21- Prathyasa rice variety) intercropped in coconut. Field experiment was conducted in factorial randomized block design with nutrient levels as first factor and nutrient schedules as second factor in three replications. Nutrient levels had significant effect on the physiological parameters. Among the nutrient levels rested, NPK applied @ 120:30:60 recorded higher total chlorophyll (2.803 mg g-1) and chlorophyll b content (1.508 mg g-1), crop growth rate (CGR) (11.23 g m-2 day-1) and relative growth rate (RGR) (0.056 g g-1 day-1) as compared to lower nutrient level tested, NPK @ 60:30:30 kg ha-1. Nutrient schedules also had significant effect (P=0.05) on the physiological parameters viz., total chlorophyll, chlorophyll a, chlorophyll b, CGR and RGR and the treatment receiving 0.2 per cent zinc sulphate and 0.04 per cent sodium borate spray at 45 DAS recorded higher chlorophyll content, RGR and CGR. Though the higher nutrient level, NPK @ 120:30:45 kg ha-1 recorded higher values for physiological parameters, it recorded the lowest grain yield. Application of NPK @ 90:30:45 kg ha-1 recorded the highest grain yield and it was followed by NPK applied @ 70:30:35 kg ha-1. Among the nutrient schedules, N applied as three equal splits, P as basal and K in two equal splits along with foliar spray of zinc sulphate 0.2 per cent and sodium borate 0.04 per cent at 45 DAS recorded the highest grain yield (3.25 t ha-1). The study clearly revealed that excessive vegetative growth is not a desirable parameter for higher grain yield.

A field experiment was conducted at Research farm of Bihar Agricultural University, Sabour (longitude 87o2’42”East and latitude 25o15?40? North at an altitude of 46 meters above mean sea level) with Katarni rice cv Bhagalpur Katarni during kharif season of 2017. The experiment with ten treatments was laid out in Randomized  block design (RBD)  with three  replications. Results revealed that among all the applied organic treatments the maximum microbial population viz., Bacteria, Actinomycetes, Fungi, Azospirillum, PSB and KSB (71.66, 27.33,  57.66, 43.66, 63.00 and 47.66 cfu × 105 g-1 oven dry soil) were recorded with the application of treatment T5 {(75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum  @ 5 kg ha-1  + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)} at panicle initiation stage  and similar trend were obtained at harvesting stage. Application of the same treatment significantly increased dehydrogenase activity by 81.62%, 10.80%, 24.86%, 15.66%, 17.83% and 18.91% when compared with application of T1 (RDF), T3 {(100 % N FYM) as basal)}, T7 {(100 % N (GM)}, T8 {(50 % N (GM) + 50 % N (V/C) at 25 DAT)}, T9 {(75 % N (GM) + 25 % N (V/C) at 25 DAT + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)} and  T10 {(75 % N (GM) + 25 % N (V/C) at 25 DAT + Panchagavya on foliar application )}, respectively. Among all organic treatments the maximum grain yield of paddy (27.39 q ha-1) was recorded in treatment T5 {(75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum  @ 5 kg ha-1  + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1)}. Among all the organic inputs and microbial inoculants, the combined application of 75 % N (FYM) basal + 25 % N (V/C) at 25 DAT + Azospirillum @ 5 kg ha-1 + PSB @ 5 kg ha-1 + KSB @ 5 kg ha-1 was found to be effective in modifying the soil microbial population and microbial community structure and grain yield of scented rice.
