Willingness to participate in a study and the factors that influence the decision in a south Indian population

What is the understanding of a participant when he enrolls for a trial? What are the factors that influence or deter the decision to enroll in a trial? Very few studies have looked into the Indian participant’s perspective and requirements when he/she decides to enroll in a trial. The aim of the study was to identify some of the factors that influence this decision. After IEC approval was obtained the participants were divided into 4 groups based on their socioeconomic status and education levels and provided with a questionnaire containing closed end questions. The answers data was tabulated and compared. Analysis of data suggests that the factors influencing people varied according to their level of education, income and their expectations from the trial. People belonging to the low socioeconomic groups were more likely to trust their doctor and were more influenced by the offers of incentives. They were mostly unaware of the controlled trial scenario and were not much aware of any risk in trials initially. Hence we suggest that the informed consent should be strictly adhered to, which may control exploitation of people in the low socioeconomic strata and low education.

RESIDUAL EFFECT OF ORGANIC WASTES ON PRODUCTIVITY OF AN ULTISOL IN ABAKALIKI, SOUTH EASTERN NIGERIA

An experiment was carried out to study residual effect of organic wastes amendment on productivity of an ultisol.The field was laid out in a Randomized Complete Block Design with four treatments of 20 t ha equivalent to 8kg/plot of burnt rice mill waste (BRMW), unburnt rice mill waste (URMW), sawdust (SD) and control which were replicated five times to give a total of twenty experimental units. The treatments were applied in 2006 and 2007 cropping seasons and residual effect studied in the third season. A hybrid of maize (Oba super II hybrid) variety was used as a test crop. Data obtained were subjected to analysis of variance (ANOVA) while means were separated with Fisher’s Least Significant Difference. The results showed that the textural class remained sandy loam. Hydraulic conductivity of organic wastes amended soil was significantly (P<0.05) higher when compared to control. While bulk density of SD amended plot was 7% lower, total porosity and hydraulic conductivity in same treatment were higher by 16 and 6% when compared to control, respectively. Total porosity, hydraulic conductivity. Available phosphorus and CEC of organic wastes amended soil were significantly (P<0.05) higher than control. Grain yield of maize was higher in BRHD, URHD and SD amended plots by 5, 9 and 13% respectively than control. Residual effect of organic wastes improved the productivity of ultisol more than control, and thus, could be recommended for sustainable soil productivity in Abakaliki agroecological farming system.
The H.264/SVC Codec for K-Hop Cooperative Video Streaming Protocol over the Hybrid Vehicular Networks

Vehicular ad-hoc network (VANET) is a subclass of mobile ad-hoc networks which provides wireless communication among the vehicles. At the point when various persons, e.g., a family or a gathering of companions, drive their vehicles for a trip together, they can structure an armada of vehicles and impart their network resources during trip. Let one member want to watch a video from the Internet. He might not have high resolution or video quality because of his restricted 3G/3.5G bandwidth capacity to the Internet. The cooperative video streaming scenario permits the requested member to ask other members of the same fleet to download video cooperatively. As such, different individuals can help can help to download parts of the video from the Internet and then forward video data to the requested member hop by hop through the ad-hoc network. This work proposes the k-hop cooperative video streaming protocol using H.264/SVC over the hybrid vehicular networks which consist of 3G/3.5G cellular network and Dedicated Short-Range Communications (DSRC) ad-hoc network. In order to smooth video playback over the DSRC-based ad-hoc network, this work proposes: (1) one streaming task assignment scheme that schedules the streaming task to each member over the dynamic vehicular networks, and (2) packet forwarding strategies that decide the forwarding sequence of the buffered video data to the requested member hop by hop. Finally, we utilize the network simulator version 2 (NS2) to simulate the proposed protocol. Based on the simulation results, the proposed scheme can estimate the assignment interval adaptively and the playback priority first (PPF) strategy has the best performance for the khop video forwarding over the hybrid vehicular networks.

A novel K-means based Glaucoma Detection

Glaucoma is an irreversible chronic eye disease that leads to vision loss. As it can be slowed down through treatment, detecting the disease in time is important. However, many patients are unaware of the disease because it progresses slowly without easily noticeable symptoms. Currently, there is no effective method for low-cost population-based glaucoma detection or screening. Recent studies have shown that automated optic nerve head assessment from 2-D retinal fundus images is promising for lowcost glaucoma screening. In this paper, we propose a method for cup to disc ratio (CDR) assessment using 2-D retinal fundus images. In the proposed method, the optic disc is first segmented and reconstructed using a novel sparse is similarity constrained coding (SDC) approach which considers both the dissimilarity constraint and the sparsity constraint from a set of reference discs with known CDRs. The proposed method has been tested for CDR assessment in a database of 650 images with CDRs manually measured by trained professionals previously. The proposed method achieves good accuracy for glaucoma detection.

A Quality Based Method to Analyze Software Architectures

In order to produce and develop a s oftware system, it is necessary to have a method of choosing a s uitable software architecture which satisfies the required quality attributes and maintains a trade-off between sometimes conflicting ones. Each software architecture includes a set of design decisions for each of which there are various alternatives, satisfying the quality attributes differently. At the same time various stakeholders with various quality goals participate in decision-making. In this paper a numerical method is proposed that based on the quality attributes selects the suitable software architecture for a certain software. In this method, for each design decision, different alternatives are compared in view of a certain quality attribute, and the other way around. Multi-criteria decision-making methods are used and, at the same time, time and cost constraints are considered in decision-making, too. The proposed method applies the stakeholders’ opinions in decision-making according to the degree of their importance and helps the architect to select the best software architecture with more certainty.

Interaction Effects of Cattle Feed Supplement and Concentrate on Rumen Fermentability and Fiber Fraction Degradability in Low-Quality Forage

DOI: 10.21276/sjavs.2018. 5.6. 9 Abstract: The objective of this study was to examine the interaction effect of additions cattle feed supplement (CFS) with feed concentrate on rumen fermentability and fiber degradability of low-quality tropical forages. The forage used is Paspalum conjugatum contain 5.44% of crude protein, feed concentrate contains 7.52% of crude protein and the CFS is containing 22.07% crude protein and 1.17% condensed tannin. The study was conducted in vitro using a split plot design with 2 main plots of full forage ration (FF) and forage + concentrate ration 60: 40% DM basis (FC), each plot was split with 4 levels of CFS (0, 5, 10 and 15% DM basis). The results showed the interaction effect of CFS addition and concentrate to crude fiber and fiber fraction degradation (P<0.05), but no interaction on rumen fermentability (P>0.05). The addition of CFS had a linear effect to increasing the rumen pH (P = 0.01), decreasing the VFA total (P = 0.03), decreasing the iso-VFA (P = 0.03) and decreasing the ratio of acetate / propionate (P=0.03). Dry matter degradability increased in CFS 10% (P <0.01), but not significant on organic matter degradability (P = 0.18). The interaction effect of CFS and concentrate was shown by decreased degradability of ADF (P = 0.03) and cellulose (P <0.01) in FF ration but an increase in FC ration and a higher linear increase to degradability of crude fiber, NDF and hemicellulose in FC than FF ration (P <0.01). The best, the CFS are given with feed concentrate at the level of 10%.
A Secure Image Steganography Using Patch Based Model

This project discusses a simple and secure steganographic system involves reversible texture synthesis and presents a design and implementation of weaving a the texture synthesis process into steganography to conceal the secret message. Texture synthesis is the method of building a large digital image from a small digital sample image by taking advantage of its structural content. A typical steganographic application includes covert communication between two parties whose presence is anonymous to a probable attacker and whose success depends on detecting the existence of this communication. We implement how to secure the communication over the medium. We can implement patch based algorithm that may conceal source texture image and embeds secret message through the process of texture synthesis.

Optimization of Surface Roughness in Wire Electrical Discharge Machining of Titanium Alloy

Wire Electrical Discharge Machining (WEDM) is extensively used for machining of complex shapes in the field of die and mould making, medical, aerospace and automobile industries for machining of too hard materials and to increase the machining productivity. Improper selection of WEDM process parameters setting can affect the machining efficiency and surface roughness due to arcing phenomenon that lead by discharge point of focus. Present study has been made to optimize the process parameters such as pulse on time, pulse off time, pulse current, servo voltage and wire tension during machining of Ti-6Al-4V titanium alloy by WEDM process using Response Surface Methodology (RSM). The analysis of variance (ANOVA) was carried out to study the effect of process parameters on process performance i.e. surface roughness. The mathematical models are also developed for surface roughness and validated with the experimental results. Further, the surface roughness of machined surface has been examined by using Scanning Electron Microscopy (SEM). The experimental results reveals that, as the pulse on time and input power increases, the surface roughness also increases. As and when the wire tension and servo voltage increases the surface roughness decreases and it improves the quality of machined surface. This paper highlights the importance of wire EDM process parameters on surface roughness and surface topography of wire electrical discharge machined surface of Titanium alloy work piece.

Influence of seaweed extracts on the growth, some metabolic activities and yield of wheat grown under drought stress

The physiological effect of drought on the 30-days-old Triticumaestivum plants was assessed and the alleviating role of seaweed extracts (Sargassumlatifolium, Ulvalactucaandtheir mixture) on drought stress was evaluated. Drought treatment (40% and 20% field capacity) resulted in a significant decrease in some growth criteria, photosynthetic pigments and activity. Furthermore, it led to oxidative stress and increased cell membrane leakage in the stressed wheat plants and resulted in the increase of antioxidant (enzymatic and non-enzymatic) defense mechanism. Pretreatment with seaweed extract of Sargassum (1.5%) or Ulva (1%) led to the alleviation of the above mentioned damaging effects of drought on Triticumaestivumduringvegetative stage while a mix of the two types of seaweed extracts resulted in antagonistic effect. Seaweed extractof Sargassumor Ulva antagonizes the oxidative damaging effects of drought not only directly through activating the antioxidative system, such as catalase, peroxidase and ascorbate, but also through providing hormones and micro nutrients essential for wheat growth. * Corresponding Author: Wedad A.

DESIGN OF A 6DB DIRECTIONAL COUPLER USING DEFECTED GROUND STRUCTURE

This paper presents the design of 6dB directional coupler in C-band. A defected ground structure is used underneath the coupled region in order to relax the requirement for a narrow slot between the coupled lines. The simulated results show that the designed coupler exhibits a coupling of 6±0.1dB across the band 4.0 GHz to 4.5 GHz, when the spacing between the coupled lines is larger than 0.1 mm. Without the slot in the ground plane, the spacing should be less than 0.04 mm in order to achieve the same value of coupling across that band. The designed device has a compact size with a dimension of 20mm x 9mm.Optimization of the design is carried out in Ansoft Designer V6.0 to meet the required specifications. Simulated results show 11% bandwidth for a return loss of better than 15dB and amplitude imbalance of 6±0.1dB over 4.0-4.5GHz. Isolation of more than 16dB has been simulated.
