INTEGRATED NUTRIENT MANAGEMENT PRACTICES IMPROVE GROWTH AND YIELD OF CARROT

AhmAd, T. , m. AmjAd, Q. IQbAl, A. NAwAz and z. IQbAl, 2014. Integrated nutrient management practices improve growth and yield of carrot. Bulg. J. Agric. Sci., 20: 1457-1465 Soil nutritional status and their availability to plant is an important abiotic factor influencing the vegetables productivity. Integration of farmyard manure (FY m), leaf manures (F), poultry manure (P m) and chemical fertilizers have pronounced effect on carrot growth and yield. In this study, 14 treatment combinations of FY m, lF, Pm and urea based on the total nitro gen requirement was tested for two carrot cultivars (T-29 and Oranza). The experiment was laid out in Randomized Complete Block Design (RCBD) with factorial arrangements and replicated thrice. Results indicated that T-29 was significantly better for all the growth and yield attributes as well as nutrient uptake in leaves except root firmness and root to shoot ratio where Oranza showed its superiority. Among different fertilizer treatment combinations of FY m, lm, Pm and urea, both carrot cul tivars performed better when half P m + half FY m was applied. Overall results revealed that combination of organic sources to meet nutritional requirements of carrot would be beneficial not only to improve carrot productivity but also reducing the rising input costs of inorganic fertilizers.
Modeling random telegraph noise under switched bias conditions using cyclostationary RTS noise

In this paper, we present measurements and simulation of random telegraph signal (RTS) noise in n-channel MOSFETs under periodic large signal gate-source excitation (switched bias conditions). This is particularly relevant to analog CMOS circuit design where large signal swings occur and where LF noise is often a limiting factor in the performance of the circuit. Measurements show that, compared to steady-state bias conditions, RTS noise can decrease but also increase when the device is subjected to switched bias conditions. We show that the simple model of a stationary noise generating process whose output is modulated by the bias voltage is not sufficient to explain the switched bias measurement results. Rather, we propose a model based on cyclostationary RTS noise generation. Using our model, we can correctly model a variety of different types of LF noise behavior that different MOSFETs exhibit under switched bias conditions. We show that the measurement results can be explained using realistic values for the bias dependency of /spl tau//sub c/ and /spl tau//sub e/.
Progressive Collapse Analysis of Planar Reinforced Concrete Frames Using a 1D Element with Distributed Non-Linearity

Summary In this paper, a highly efficient 1D discrete element is developed for progressive collapse analysis of reinforced concrete planar frames. The element takes advantage of the force- interpolation and total secant stiffness approach, as well as a non-local averaging technique adopted to maintain the objectivity of displacement and force responses. Dynamic load distribution, softening of concrete under compression, effect of mass type (consistent or lump) and catenary action of the beams are addressed. Concerning geometrical non-linearities, the strains are assumed to be small; however, the effect of transverse displacement on the axial strain is large and it is taken into account. The accuracy and efficiency of the element for static and dynamic progressive collapse assessment of the reinforced concrete frames is demonstrated through some numerical examples.

The seeder of maize and bean was the machine indicated for the majority of farmers as their greatest necessity.
Composite Wood-Concrete Beams Using Utility Poles: Time-Dependent Behavior

This paper describes the behavior of wood-concrete composite beams in which the wood layer is composed of recycled utility poles. Two full-scale laboratory specimens of 7,500-mm (295-in.) span were constructed, with the concrete slab cast on the timber poles left unshored. The connection was obtained by cutting six notches in the timber poles. A threaded steel dowel is placed in each notch extending through both layers with a nut on the bottom of the beam that can be tightened once the concrete has cured. Since the material in each layer exhibits a time-dependent response, it is necessary to examine the effects of sustained loading. After 28 days of initial curing of the concrete layer during which the midspan deflection was monitored, both beams were subjected to the service load to estimate the composite efficiency. The beams were very stiff and values of 96% and 98% were obtained, respectively, demonstrating the high efficiency of the notched connection system used. A comparison was made with results o.

Experimental Investigation of Developing Plug and Slug Flows

In this work, particular efforts are devoted to the experimental investigation of developing intermittent flows (plug and slug flows) in horizontal pipes in order to attain a thorough physical understanding of the internal structure of these two-phase flow patterns. Experimental data is acquired with specific attention to the development of stratified and wavy flow regimes to intermittent flow regimes. The distribution of the phases, several relevant flow characteristics and the behaviour of the bubbles in the liquid phase are identified by means of wire-mesh sensor data. The main differences between plug and slug flow are elucidated and the influence of the slug void fraction on the characteristics of these flows as well as the behaviour of the dispersed bubbles in the slug body are analysed in detail. The simultaneous use of the PIV technique and the Pulsed Shadowgraph technique are adapted for horizontal two-phase pipe flows within this work, allowing the study of the kinematics of stratified, wavy, plug and slug flows. Turbulent quantities of these flows are also analysed.
Supporting the information technology champion

The literature on strategic uses of information technology suggests that "champions" are often a key to successful implementation. This article describes a field study of 15 information technology (IT) champions and their needs for support from their information systems units. Innovation research is used to hypothesize that IT champions, like other champions, need information, technical resources, and political support from their information systems department units. Interview findings suggest that IT champions strongly value (1) assistance in developing information to help sell their IT vision, (2) a flexible implementation process, and (3) legitimation their ideas for using information technology. Moreover, IT champions do not want bureaucratic process or arm’s length dealings with information systems departments. The way a firm should conduct its dealings with an IT champion depends in large part on a number of organizational factors, including the IS department’s mission.
Increase of parasitic resistance in shallow p/sup +/ extension by SiN sidewall process and its improvement by Ge preamorphization for sub-0.25-/spl mu/m pMOSFET's

Anomalously high parasitic resistance is observed when SiN gate sidewall spacer is incorporated into sub-0.25-/spl mu/m pMOSFET's. The parasitic resistance in p/sup +/ S/D extension region increases remarkably by decreasing BF/sub 2/ ion implantation energy to lower than 10 keV. It is confirmed that low activation efficiency of boron in p/sup +/ extension is the reason for such high parasitic resistance. The reduction of activation efficiency of boron may result from hydrogen passivation of boron acceptor; Fourier transform infrared absorption (FT-IR) measurement suggests that diffused hydrogen from SIN into p/sup +/ extension region forms the silicon-hydrogen-boron complex. It is also found that the activation efficiency of boron correlates well both with implantation energy of BF/sub 2/ and the amorphization rate of substrate. Therefore, in sub-0.25-/spl mu/m era, the extra amorphization step is essential not only to form a shallow junction but also to enhance boron activation. Germanium preamorphization implantation (Ge PAI) is hence applied to p/sup +/ extension of 0.15 /spl mu/m pMOSFET's. It is finally demonstrated that this Ge PAI process reduces the total parasitic resistance to improve the drain saturation current by up to 10%.
PERPETUAL PAVEMENTS IN TEXAS: STATE OF THE PRACTICE

15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Monitor Field Performance of Full-Depth Asphalt Pavements to Validate Design Procedures URL: http://tti.tamu. edu/documents/0-4822-1.pdf 16. Abstract As of December 2005 TxDOT has four perpetual pavement sections in service and another four under construction. Project 0-4822 was initiated to perform a structural assessment of these thick asphalt pavements, to identify strengths and weaknesses in the existing structures, and to provide guidance for future designs. This Year 1 report provides an evaluation of the existing sections. It is based on extensive nondestructive testing with Ground Penetrating Radar (GPR), Falling Weight Deflectometers (FWD), field coring, and limited laboratory testing. On a positive note, the stone-filled mixes used in these structures are considerably stiffer than the dense graded mixes traditionally used in Texas. Design moduli values of 750 ksi and 1000 ksi are recommended for future designs with the Stone Matrix Asphalt (SMA) and 1-inch stone-filled (SF) layers. However, three major problems were identified. Firstly, the 1-inch stone-filled layers are prone to vertical segregation. Several of the sections were found to have severe honeycombing at the bottom of the lifts. These mixes are excessively coarse with low asphalt binder contents around 4 percent. Mix design procedures must be modified to eliminate this problem. Secondly, all but one of the projects was found to have de-bonding occurring between layers. This will severely impact the fatigue life of these pavement sections. Thirdly, better guidelines need to be developed on what constitutes a foundation layer for perpetual pavements. Several of the current foundation layers are not thought to be permanent. 17.
Vector Quantizers and Predictive Quantizers for Gauss-Markov Sources

Low-rate vector quantizers are designed and simulated for highly correlated Gauss-Markov sources and the resulting performance is compared with Arnstein's optimized predictive quantizer and with Huang and Schultheiss' optimized transform coder. Two implementations of vector quantizers are considered: full search vector quantizers-which are optimal but require large codebook searches-and tree searched vector quantizers-which are suboptimal but require far less searching. The various systems are compared on the basis of performance, complexity, and generality of design techniques.
Effects of Measurement Error on Process Signal Detection

Many data comes from a process with variables having non-normal distributions. The commonly used Shewhart variable control charts which depend heavily on the normality assumption should not be applied here. Further, measurement error of an instrument or gauge is an important factor in industry that influences the outcome of a process. Incapability of the instrument or gauge would cause the observation measure deviates from the true value and consequently lead to a false discrimination between good and bad service quality and manufacturing parts. In this study, we propose a new EWMA control chart to monitor the exponentially distributed service time between consecutive events with the measurement error instead of monitoring the number of events in a given time interval. We showed that, in the case of the measurement error following a normal distribution, the performance of the EWMA-M chart is significantly affected. We suggest letting for keeping the chart with the same detection ability; otherwise, the chart’s detection ability would be much poor than the charts with no measurement errors
COVID-19 AND CONVALESCENT PLASMA THERAPY

: Introduction: The novel coronavirus-2 (SARS-CoV-2) is responsible for the COVID-19 pandemic and to-date, has affected more than 200 countries and over 13 million people worldwide with an excess of 550,000 deaths since its emergence in December 2019. Although several treatment approaches are under scientific scrutiny, there is no definitive treatment for SARS-CoV-2 because of a lack of hard evidence. One of the treatment modalities under consideration is convalescent plasma (CP) therapy, a historical therapeutic tool that has been used repeatedly to treat several infections successfully. Herein we discussed the mechanism of CP therapy's mechanism, in addition to pertinent clinical aspects of the therapy, its potential adverse effects, and recent scientific evidence favoring CP therapy. Methodology: The aim of this systematic review was to determine the efficacy of CP therapy in COVID-19 in addition to highlighting the various facets of CP therapy. Multiple search engines including, but not exclusive of, PubMed, Google scholar and science direct were used to look for relevant primary studies using pertinent mesh terms. 54 research articles were identified that focused on the mechanism of action, various clinical considerations, adverse effects of CP therapy, as well as evidence in favor of the use of CP therapy in COVID-19. Articles published between 1990 and 2020 were included in this systematic review as per the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Results: In the light of these findings, CP therapy appears to be a potentially safe and effective therapeutic modality particularly in the treatment of critically ill patients with COVID-19. In spite of the encouraging outcome of CP therapy in COVID-19 in small nonrandomized clinical trials, larger randomized clinical trials are required before this treatment modality can be employed in the treatment of COVID-19 on a large scale. However, it can be used empirically in critically ill COVID-19 patients as a life-saving measure due to the unavailability of other proven therapeutic modalities. Clinical judgement and risk vs benefit assessment should be done when using CP therapy on an empirical basis. Conclusion: CP therapy appears to be an effective therapeutic approach for the treatment of emerging pathogens, particularly in the absence of definitive antiviral agents or vaccines. The potential antiviral and immunomodulatory eﬀects of CP should be evaluated in COVID-19.
The Impact of ICT Towards Saudi EFL Students’ Writing Skills: A Quasi-Experimental Study

This study aimed to investigate the impact of using the word processor application on the writing achievement of Saudi EFL learners at Jubail Technical Institute. It used embedded-experimental mixed methods research design in which the qualitative data set provides an auxiliary role in a study that is primarily quantitative. Nested sampling technique was used to select participants for both the dominant quantitative and the auxiliary qualitative phases of the study. The participants were divided into two groups: the experimental group, which studied writing using the word processor, and the control group, which learnt writing using the traditional method. It was hypothesized that the experimental group participants would have a higher achievement in a writing performance test than those of the control group. After establishing that the two groups had homogenous writing abilities before the treatment, post-test results showed that the experimental group participants had a statistically significantly higher achievement in the writing performance test (t(67) = 6.21, p < . 001) than the control group. The study recommended introducing computer-assisted writing programs in composition classes and training teachers on how to use such programs to help students develop their writing skills.
Evaluation of Some Maternal and Neonatal-Associated Risk Factors in Early On-Set Neonatal Thrombocytopenia in Delta State, Nigeria

Background: The growing prevalence of neonatal thrombocytopenia at birth in recent times is a source of concern. Hence, the assessment of maternal and neonatal risk factors associated with early on-set neonatal thrombocytopenia to forestall any complications that may lead to lifelong residual defects or even death among new-borns in this locality. Methods : From a total of 374 newborns at birth, 35 (9.4%) newborns developed thrombocytopenia and served as cases while, 339 (90.6%) were non-thrombocytopenic newborns and served as controls for this study between April 2016 and November 2016. Platelet count was determined on cord blood immediately after delivery using Sysmex KX-21N auto-haematology analyzer. Platelet count from the analyzer correlated with the estimated platelet count from the peripheral blood film evaluation. Results: Incidence of twin delivery (33.3%) was higher among the risk factors associated with neonatal thrombocytopenia. Twin gestation was significantly associated with neonatal thrombocytopenia (P = 0.0062). Conclusion: New-borns from mothers with multiple pregnancies should be thoroughly evaluated for any possible complications of thrombocytopenia at birth to reduce perinatal morbidity and mortality.
Cholesterol Level in Covid-19 Patients Related to Severity and Mortality: A Case Series and Literature Review

Coronavirus Disease 2019 (COVID-19) is a communicable disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). December 2019 in Wuhan, China, is the time and place where the first pneumonia case which SARS-CoV-2 causes was found, and WHO designated COVID-19 as a pandemic by March 2020. There are reported cases of dyslipidemia associated with SARS patients, albeit rare. Several case reports showed lower cholesterol levels compared to healthy subjects. Therefore, some argued that dyslipidemia could occur in COVID-19. Several studies have revealed that hypolipidemia is positively correlated with the severity of COVID-19. In Ulin Regional Hospital Banjarmasin, several cases found higher cholesterol levels in asymptomatic and mild-moderate COVID—19 survivor compared to patients with severe/critical COVID-19and non-survivor. Two patients in the non-survivor group showed a significant decrease in cholesterol level compared to baseline, and five patients had <150 mg/dL cholesterol level during the examination. Four mild-moderate COVID-19 survivors had cholesterol levels that were greater than 150 mg/dL at the first examination and did not decrease during the evaluation. Cholesterol is thought to play an important role in the pathological development of COVID-19, and it is associated with severity and mortality, which requires further studies.
Tracking semiconductor part changes through the part supply chain

The supply chain for electronic products has grown more complex over the last several decades, making the tracking of semiconductor part changes through the supply chain more difficult. Electronic systems manufacturers must now take an increasingly active role in tracking part changes, and may need to establish contractual agreements to guarantee that they receive the information they need. This article provides the information needed for system manufacturers to plan their change control policies. The relevant standards and current industry practices for change control and notification are discussed. Policies of major manufacturers, distributors, and contract manufacturers are analyzed. Examples of commonly made changes and the reasons why they are made are provided. Finally, policy recommendations for electronic systems manufacturers are made.

Efficacy Determination of Various Base Networks in Single Shot Detector for Automatic Mask Localisation in a Post COVID Setup

ABSTRACT The COVID-19 pandemic is one of the rarest events of global crises where a viral pathogen infiltrates every part of the world, leaving every country face an inevitable threat of having to lock down major cities and economic hubs and put firm restrictions on citizens thus slowing down the economy. The risk of removal of lockdowns is the emergence of new waves of a pandemic causing a surge in new cases. These facts necessitate the containment of the virus when the lockdowns end. Wearing masks in crowded places can help restrict the spread of the virus through minuscule droplets in the air. Through the automatic detection, enumeration, and localisation of masks from closed-circuit television footage, it is possible to keep violations of post-COVID regulations in check. In this paper, we leverage the Single-Shot Detection (SSD) framework through different base convolutional neural networks (CNNs) namely VGG16, VGG19, ResNet50, DenseNet121, MobileNetV2, and Xception to compare performance metrics attained by the different variations of the SSD and determine the efficacies for the best base network model for automatic mask detection in a post COVID world. We find that Xception performs best among all the other models in terms of mean average precision.
