Conjoint effect of Vermicompost and nitrogen on inceptisols of western Uttar Pradesh

Vermicompost and nitrogen scheduling on periodic nutrients availability in soil at different growth stages of rice crop were studied with rice (PB-1) and wheat (PBW 502) with two field experiments conducted during 2011-12 and 2012-13 in the Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. Analysis of soil for different physicochemical properties of soil at different growth stages of rice was done. Availability of soil N increased due to addition of vermicompost and more availability was found with delayed application of vermicompost. Phosphorous and potassium were higher in those treatments where vermicompost was applied with 75% N and 100 % PK. Slightly lower soil pH was found with the application of 100% NPK. At all the stages maximum electrical conductivity was found in T1 where no fertilizer was applied. At flowering highest organic carbon percent in soil was found in case of T9 while at harvest in T10 during both the years. With exception of T1 rest of the treatments were found statistically at par in respect of available soil Mn during both the years. The application effect of vermicompost on the availability of soil copper was not found at any stage. Availability of zinc at harvest did not varied significantly due to timing of vermicompost. At harvesting Fe varied from 10.75 to 13.13 and 10.27 to 12.27 mg kg during 2011 and 2012 respectively.
The Power of Perception: Beliefs About Memory Ability Uniquely Contribute to Memory Performance and Quality of Life in Adults Aging with Traumatic Brain Injury

Abstract Objective: Personal beliefs about memory ability, which comprise memory self-efficacy (MSE), can influence memory performance in healthy older adults. Self-efficacy theory also predicts that MSE biases self-perceptions of functioning more globally, potentially impacting daily activity beyond cognitive performance. People with traumatic brain injury (PwTBI) frequently report debilitating memory problems long after acute recovery, but little is known about how MSE affects health outcomes in this population. We examined demographic and clinical correlates of MSE, as well as its relationship to memory test performance and health-related quality of life (QOL), in older adults with chronic moderate-to-severe TBI (msTBI). Method: One hundred fourteen adults, aged 50+ and at least 1 year post-msTBI, underwent neuropsychological testing to assess their memory functioning. Participants also self-reported levels of psychological distress, MSE (Cognitive Confidence subscale of the Metacognitions Questionnaire), and health-related QOL (Quality of Life after Brain Injury questionnaire). Results: Demographic and injury-related predictors showed weak correlations with MSE. Although the relationship between MSE and general psychological distress was robust, only the former significantly predicted memory performance. Bivariate analyses revealed significant relationships between MSE and five out of the six QOL domains assessed. Multivariate linear regression revealed a significant impact of MSE on overall QOL independent of demographic and clinical variables. Conclusions: Our findings support a unique role for MSE in both the objective cognitive performance and subjective health of PwTBI. Increased focus on self-perceptions of ability and their impact on measured outcomes is an important step towards personalized rehabilitation for adults with chronic msTBI.
Magnetorheological elastomer and its application on impact buffer

In this study, a new magnetorheological elastomer (MRE) based buffer is proposed and its vibration isolation performance is investigated. The MRE buffer with a compact structure is first designed in order to accomplish the maximization of the variable stiffness range. The working characteristics of the MRE buffer are then measured and the model of MRE is established. On the basis of the experimental data, the control model of the MRE buffer is also formulated. A two-degree-of-freedom dynamic model with an MRE buffer is then developed. An intelligent control strategy, human simulated intelligent control (HSIC), is proposed to reduce the impact during the drop crash. Finally, the proposed MRE buffer and controller are validated numerically and experimentally. The results show that the proposed MRE buffer and the control strategy can reduce the impact acceleration effectively.
Disambiguating language attitudes held towards sociodemographic groups and geographic areas in South East England

Abstract Using a novel, digitized method, this paper investigates the language attitudes of 18- to 33-year-olds in South East England. More broadly, this paper demonstrates that disambiguating the language attitudes held towards sociodemographic groups and geographic areas is paramount to understanding the configuration of language attitudes in an area, particularly for areas with high cultural and linguistic heterogeneity. A total of 194 respondents evaluated the speech of 102 other south-eastern speakers. Results reveal an imperfect mapping between language attitudes held towards geographic areas and speakers from these areas. Although East London and Essex are the most negatively evaluated areas, speakers’ demographic and identity data is the primary factor conditioning language attitudes. Across South East England, working-class and/or ethnic minority speakers, as well as those who identify their accent in geographically marked terms, are evaluated most negatively, which is compounded if they are from East London or Essex.
Desenvolvimento e produtividade do maracujazeiro-amarelo irrigado sob diferentes lâminas de irrigação em ambiente protegido e natural

Irrigation is a practice that can offer the possibility of a product with a better quality, and increase the productivity. The cultivation of passion fruit in greenhouse is not a common activity so it is necessary to research this condition, especially irrigation. The objective of this study was to evaluate the effect of different soil water tensions on the culture behavior in greenhouses and natural condition in the region of Lavras - Minas Gerais - Brazil. The experiment was conducted at the experimental area of the UFLA-Engineering Department in a randomized block design with four replications. Four soil water tensions were previously established, which consisted of treatments: 15, 30, 45 and 60 kPa, in a 0.20 m deep. It was concluded by the results obtained that: irrigation of passion fruit, under tensions of up to 60 kPa, both in greenhouse at in natural conditions of cultivation, did not affect the total, commercial and noncommercial productions; cultivation in greenhouses promoted a faster growth of the plants (height and stem diameter), and also anticipated the harvest when compared to the natural conditions; the irrigation can be performed for water tension of 60 kPa in soil, in greenhouses and natural conditions without compromising the crop productivity; the tension of water in the soil affects plant growth, however, did not affect the stem diameter.
New earth reinforcement method by soilbags (Donow)

This paper presents a new earth reinforcement method by soilbags ("Donow" in Japanese) and its applications to such earth reinforcements as reinforcement for ballast foundations under railway sleeper, reinforcement for soft building foundations and construction of retaining walls. The strength properties of soilbags are studied theoretically and verified through the biaxial compression tests on 2D model soilbags and the unconfined compression tests on real soilbags with various kinds of materials contained. It is found that the high strength of the soilbag is produced due to the tensile force of the bag when the soilbag is subjected to an external force and the bag expands. This reinforcing mechanism contains a "reversal idea" of making use of an external force, which is the "enemy" against the foundation. The earth reinforcement using soilbags has the advantages of improving greatly the bearing capacity for soft ground, resisting flexibly against deformation and being friendly to our environment with less noise during construction and no use of any chemical agents. It also has the effect of reducing traffic- or machine-induced vibration and preventing frost heave.
Numerical Investigation of Film Cooling Performance With Different Internal Flow Structures

Four coolant channel configurations, including supply plenum without crossflow, smooth channel with crossflow and ribbed channels with crossflow ( 135° and 45° angled ribs), are simulated to find out the effect of internal flow structures on the external film cooling performance. Reynolds Averaged Navier Stokes (RANS) simulations with realizable k-e turbulence model and enhanced wall treatment are performed using a commercial code Fluent. Blowing ratios cover a range from 0.5 to 2.0. For the three cases with crossflow, a constant Reynolds number, ReDh, is fixed as 100000.Particular attention has been paid to the flow structures and counter-rotating vortices. Helical motion of secondary flow is observed in the hole of the smooth case and the 45° ribs case, inducing strong velocity separation in the cooling hole and blocks at the entrance and exit. In the two cases, the cooling-air jet divides into two parts after being blown out of the hole and a pair of skewed vortices appears downstream. In the 135° ribs case, the vortex in the upper half region of the secondary flow channel rotates in the same direction with the hole inclination direction, the straight stream lines are generated and therefore lower loss and higher discharge coefficient. Experimental data of the smooth case and the 135° ribs case show the good agreement with the numerical results.Copyright © 2014 by ASME
Nationwide field measurements of wind turbine noise in Japan

A research project entitled “Research on the evaluation of human impact of low frequency noise from wind turbine generators” has been conducted over the past 3 years from fiscal year 2010, funded by a grant from the Ministry of the Environment, Japan. In this study, noise measurements were performed in the immission areas around 34 wind farms nationwide. For the survey, measurement instrumentation was devised to cover low frequency components including infrasound, and measurement techniques were investigated in order to detect wind turbine noise in ambient environmental noises. Each field measurement was performed continuously and unattended for 120 h, and sound pressure signals were recorded on specially manufactured wide-frequency-range sound level meters. From the recordings, 1/3-octave-band and A-, C-, and G-weighted sound pressure levels were obtained during the time when the wind turbines were under a rated operation condition. Amplitude modulation sound, which is a serious problem of wind turbine noise, was also analyzed with emphasis on the sound pressure level variation and modulation period. In parallel with the measurements around wind farms, 16 control areas without wind turbine noise were chosen and the residual noise was measured for comparison. © 2014 Institute of Noise Control Engineering.

A Stated Preference Analysis of Real-Time Public Transit Stop Information

This article describes a study undertake to examine the benefits derived from real-time information provided at public transit stops. The authors examined the preferences between several options for receiving real-time public transit stop information. The authors wanted to ascertain if the provision of real-time public transit information can remove or alleviate some of the uncertainty and frustration associated with using public transit. They applied a nested logit model structure to examine the benefits derived from accessing real-time public transit information. These models are applied to segments of the dataset to ascertain how the mode of transport used by the respondents impacts the benefits derived from using real-time public transit information. The sample used was office-based workers in Dublin, Ireland's central business district. The authors found that passengers derive the greatest benefit from accessing transit stop information from real-time information displays. The second highest usefulness was obtained when passengers could access transit stop information via a mobile phone short message service (SMS). Bus users were found to gain the highest benefit from the provision of real-time transit stop information. In general, users who experience longer waiting times and greater frustration levels were more likely to derive a benefit from using real-time information.
Work trip travel demand modelling in Kingston Township, Ontario, Canada

This paper describes a procedure, using logit analysis, to model the mode choice decision of work trip commuters residing in a small municipality, Kingston Township, in the province of Ontario, Canada. Particular emphasis is given to assessing the appropriateness of including perceptual variables as mode choice determinants in the modelling procedure. Results indicate that a carefully designed survey procedure using a small data base, and the inclusion of perceptual and non-perceptual variables in the demand model contribute to the goodness-of-fit of the model to the sample data. It is concluded that the modelling procedure may offer potential for evaluating transportation policies designed to ameliorate work trip related problems confronting Kingston township commuters.

A comparison of silicon and germanium photovoltaic power converters for power over fibre

In this study, we compare the practical implementation of both silicon and germanium Photovoltaic Power Converters (PPCs). Simulations have previously shown that silicon PPCs can produce up to 43% optical to electrical power conversion and germanium PPCs can produce conversion efficiencies as high as 22% when illuminated by 980nm light. Moreover, germanium can produce conversion efficiencies of up to 36% when illuminated by 1550nm light. Here, we compare these results to real power conversion efficiencies of off-the-shelf silicon and germanium photodiodes, producing 9.9% and 8.0% conversion efficiencies, respectively for 980nm. Furthermore, we show germanium produces conversion efficiencies up to 14.6% under illumination of 1550nm light. A discussion of the limitations is made. The results show there is a peak efficiency point corresponding to a specific input optical power. We also show that the power over fibre signal can be successfully combined with communications signals, using wavelength division multiplexing, and that the multiplexed signals can be separated without significant loss of signal, or power conversion efficiency. In addition, we investigate the affects of free space problems, such as divergence and misalignment, in both the lateral and longitudinal directions. As expected, optical alignment plays a significant role in producing maximum power conversion.
Lateral-Distortional Buckling of Hollow Flange Beams

While the flanges of cold-formed hollow flange beams (HFBs) are very stiff torsionally, their webs are comparatively flexible, and may allow web distortion effects to reduce their resistances to lateral buckling. There is no simple formulation for predicting the effects of web distortion on the lateral buckling of HFBs. As a result, structural designers are unable either to check or to extend the available elastic buckling predictions; thus code writers are not able to provide explicit formulations for the effects of distortion. The conversion from elastic buckling to strength for HFBs is also questionable, since cold-formed beams have different stress-strain curves, residual stresses, and geometrical imperfections from those of hot-formed beams. This paper deals with these problems, first by finding a simple but sufficiently accurate closed-form solution for the effects of distortion on the elastic lateral buckling of simply supported HFBs in uniform bending, and then by developing an advanced theoretica.
The availability and utilization of information communication technologies (ICTs) in college of education (COE) Minna, a survey

This study surveyed the availability and use of information and communication technology (ICT) facilities in the college of education (COE) Minna, Niger State Nigeria. A survey research design was used for this study. One set of questionnaire was used to collect data for the study. A total of 2, 500 staff of the college constituted the population of the study. To obtain a sample for this study, a proportionate random sampling of 10% was used to draw the sample from the group – the academic staff and non – academic staff senior. Some of the ICT facilities found include computers, CD-Rom, printers internet video tapes, audio tapes, microphone etc The study also found that despite the fact that a lot of benefits accrue from the use of ICT facilities, their uses are still very low in the college. To improve the usage therefore the study recommends that the school authority and government should provide more excess and training for the staff. Key Words: Information, availability, utilization, ICT, College, education, Minna.
Modeling the Performance of Personalized Ventilation under Different Conditions of Room Air and Personalized Air

Building-related health complaints and sick building syndrome (SBS) represent significant health problems. Personalized ventilation (PV) is able to provide better inhaled air quality since the fresh air is supplied directly to the breathing zone “gently. ” In this paper, after the numerical methods are validated by experiments, a seated computational thermal manikin (CTM) with geometry of a real human body is used to carry out the parameters study of PV. The modeling outcome shows that in a stagnant environment the human body is enclosed by the thermal plume, whose intensity is affected by the room air temperature. Warm rising airflow around the human body will entrain room air into inhalation and thus decreases the fraction of personalized air in the inhaled air. A uniform invading airflow in the horizontal level with the speed of 0.2 m/s (40 ft/min) is strong enough to tear away the thermal plume at the windward side of the human body. Its effect on the performance of PV is dependent on the flow direction. The benefits of personalized air supplied at a low rate limited by draught criteria are very sensitive to the ambient air conditions, which are, in turn, controlled by the background air-conditioning system.
A Prospective and Nutrition-Related Nomogram Model for Prognosis in Colorectal Cancer Survival: A Multicenter Cohort Study in China

BackgroundColorectal cancer (CRC) is a common malignancy with high incidence of malnutrition. Increasing evidence showed that nutritional status could be a prognostic indicator of cancer survival. However, there were few prognostic models involving nutrition-related indicators in CRC. This study aimed to develop a nutrition-related prognostic model for CRC survival.MethodsThis multicenter retrospectively primary cohort data included 1,373 CRC patients, and the external validation cohort enrolled other 108 CRC patients. LASSO and multivariate regression analyses were used to select prognostic indicators and develop the nomogram. We performed C-index, calibration curves, and DCA to assess the discrimination, calibration, and applicability. Finally, the indicators of the nomogram model were used as adjustment factors. Multivariate Cox survival analyses were performed to investigate the benefit of the Patient-Generated Subjective Global Assessment (PG-SGA) and Global Leadership Initiative on Malnutrition (GLIM) malnutrition criteria to CRC prognosis.ResultsFive prognostic indicators (TNM stage, radical resection, reduced food intake, activities and function decline, and low albumin) were chosen to develop the nomogram. C-index of the nomogram was 0.74 (95% CI 0.72-0.77) and 0.72 (95% CI 0.62-0.81) in the primary cohort and validation cohort, which were higher than other models. Calibration plots and DCA showed that the nomogram model has a good consistency and clinical benefit in predicting CRC survival. Multivariate Cox survival analysis suggested moderate (P<0.05, HR 1.32, 95% CI 1.002-1.75) and severe malnutrition (P<0.001, HR 1.69, 95% CI 1.27-2.25) were associated with worse overall survival (OS) in CRC using the PG-SGA criteria. However, there was no prognostic significance in GLIM criteria (all P>0.05). Finally, stratified analysis suggested that malnourished CRC patients with low albumin synergistically increased the death risk of CRC OS both in PG-SGA and GLIM. (P for interaction = 0.007 and 0.004, respectively)ConclusionThis study established a prospective model to predict the OS in CRC patients using nutrition-related indicators. Moreover, we also found that PG-SGA had a better prognostic and predictive efficiency in CRC than GLIM. These findings grant further verification.
Experimental Investigation into the Effect of Gurney Flaps on Various Airfoils

The aerodynamic effects of the application of Gurney flaps of different heights and chordwise locations to five airfoils have been investigated in the Pennsylvania State University low-speed, low-turbulence wind tunnel. The effectiveness of each Gurney flap/airfoil combination is measured by the change in the maximum lift coefficient of the airfoil. When grouped by flap height and plotted against chordwise location, there is considerable scatter in the data, indicating that the effectiveness of the Gurney flap is strongly influenced by airfoil shape. Two anomalous cases are considered in detail. In the first case, the increase in cl,max is considerably different for two airfoils with the addition of a Gurney flap having the same height and mounted at the same chordwise location. The second case is one in which a Gurney flap of a specific height and mounting location is found to increase cl,max on one airfoil and decrease it on another. For these cases, pressure distributions, lift curves, and drag polars .
Localization of the Epileptogenic Lesion by Focal Slow and Beta Wave MEG Activity

INTRODUCTION: Usually Ihe epileptogenic zone is removed to eure the epilepsy. But recent results with structural lesions showed that the removal of the epileptogenic lesion (assumed to be the original cause of a seizure disorder) is important for the clinical outcome (Avvad et al. 1991, Cascino et al. 1992). In addition, the recording of the activity produced by the epileptogenic zone has a considerable drawback (seizure(s) must be recorded), whereas the activity associated with epileptogenic lesions can easily be obtained without the need to record interictal spike activity. Thus the localization of the epileptogenic lesion is of grcat intcrest.
