Abstract

The range vegetation characteristics were studied in closed and open systems at flowering and seeding in (El Rosa) El khuwei locality at September and November 2009. Sampling was using 2Km2 plots in a radiating manner from the centre of plot. CRD was used to analyses all parameters. Results of biomass, plant density and plant cover in the closed systems at the flowering were significantly (P < 0.0001) higher. These parameters were significantly lower in the open system at seeding. Bare soil and litter were significantly (P < 0.0001) higher in the open system at seeding. Total forage productivity kg/ha was significantly (P < 0.05) higher in the closed system at the flowering and least in the open system at seeding. Carrying capacity was significantly (P < 0.0001) higher in closed system at seeding and leas in open at flowering. Stoking rates in the closed system at flowering were significantly (P < 0.0001) higher and least in the open system at seeding. Plant frequencies were higher in the closed system at the two growth stages than open system like Huskneet (Cenchrus biflorus) Bano (Eragrostis tremula) Gaw (Aristida sp) Difra (Echinocloa colonum) Aboelrakhus (Andropogon gayanus) Fisiya (Fimbristyls hispidula) and Tmrfar (Oldenlandia senegalensis) had higher frequencies. However leflef (Luffa aegyptiaca) and Himeira (Hymenocardia acida) had lower frequencies. Simeima (Sesamum alatum) Buid (Commelinia subulata) Abodaib (Ceraotheca sesamoid) Shuleny (Zornia glochidiata) and Rabaa (Zalea sp) were found only in the closed system at flowering. Nuida (Sida cordofolia) were only found in the open system at the two growth stages. It was concluded that the closed system had higher plant density and cover, biomass, plant frequencies and forage production. Bare soil and litter were higher in open system at seeding. Carrying capacity was higher in the closed system at seeding. Stoking rates in the closed system at flowering were higher. Indicate that direct effects on different system vegetation characteristics, productivity, caring capacity and stocking rates.

Abstract

Experiments were conducted on the efficacy of raw DE and plant powders (Jatropha curcas seed and leaf powders of Eucalyptus and Ricinus) for their insecticidal potential against Callosobruchus subinnotatus infesting stored bambara groundnut seeds. The treatments consisted of the raw DE, plant powders, actellic dust (2%) as check and an untreated control. Thirty adults 0-3 days old were used to infest 100 g bambara groundnut seeds (cv. Ka’aro). Raw DE was used at 0.3, 0.6 and 0.9g/100g seeds and plants powders at 0.5, 1.0, and 2 .0g/100g seeds each replicated three times in completely randomized design. Adult mortality was recorded from 24 to 96 hours; progeny emergence as well as percentage seed damage and viability were assessed. The result revealed that, raw DE at 0.9g recorded significant (P<0.05) mortality of 78.81% and JSP at 2.0g gave 63.52 % mortality both after 24 h of exposure. Higher mortality was observed for higher dosage of all treatments after 96 h. Progeny production was significantly (P<0.05) inhibited in treated seeds. The results therefore suggested that, raw DE and plant powders are prom­ising alternatives to synthetic pesticides against C. subinnotatus in bambara groundnut seeds.

Abstract

A new method of magnetic-depth research outcrops of rocks was proposed in this paper. This combination of methods for studying the magnetic field and magnetic properties "in situ" and laboratory measurements. As an example we present the results of other areas of the Ukrainian shield at the Southern Bug. Compilation of new data on the existing map allows you to combine two previously separate T-anomalies together into a new T-anomaly continued in the north-east. Logical to assume that the banks are on oppositebody (length 1000 m), which is the source of the anomalous T.

Abstract

The paper is concerned with posterior analysis of exponentiated gamma distribution for type II censored samples. The expressions for Bayes estimators and associated risks have been derived under different priors. The entropy and quadratic loss functions have been assumed for estimation. The posterior predictive distributions have been obtained and corresponding intervals have been constructed. The study aims to find out a suitable estimator of the parameter of the distribution. The findings of the study suggest that the performance of estimators under gamma prior using entropy loss function is the best.

Abstract

A structure bases on new observations of physics theories that able to express today’s scientific developments. This article is a starting points of philosophically perceive in particle physics. It is imagining and accenting on the new quantum particles which exist beyond the bosons and fermions. Topics for discussion about space and super quantum filed has been written due to justify physical fields and particles. In general, the transfer particles, fields and particles produced have been established in this approach. Presenting an approach and providing a new perspective on the primary structure of the world and around us from past until now, is the integral part of the different science such as physics.The scholars and experts in the area of elementary particles and fields generally have proposed just a model for the patterns and structures of matter through them the result of practical experiments and theoretical calculations were orientated to each other. In other words, the structure and definition of elementary particles haven’t provided which integrate all the characteristics of fields and particles from bosons to fermions and describe their characteristics and essence. So well we can try to investigate the word and structure of cosmos before and much earlier than the Big Bang moment. Due to this view, many uncertainties and vague concepts will be cleared and the way to interesting theories and equations in physics will be opened to us.

Abstract

Development of mathematical model to predict the transport of dissolved arsenic in groundwater influenced by seepage velocity has been carried out. This model was developed to monitor the rate of concentration at different period and depths. High and low concentrations were observed at different periods and depth as presented in the figures. These conditions can be attributed to soil stratification deposition in the study location and the influence of man-made activities. Based on these facts, it is recommended that risk assessment should be thoroughly done for soil and water and the predicted model should be applied in design and construction of groundwater system in the study area.

Abstract

Hydroforming processes have been widely applied in many different industrial fields including aerospace, automotive, and modern plastics for weight-reduction and strength enhancement. Hydroforming on tubular products is better than the process of welding tubular assemblies from stampings including increased strength, reduction of work applied to the unit weight, decreased processing and tool costs, improved structural stability, less secondary operation, enhanced stiffness, and more uniform in product thickness. Although the hydroforming becomes popular manufacturing methodology, few researches have been done to study the hydroforming mechanism through computational modeling and simulation. This paper focuses on the study of hydroforming process and mechanism based on computer-aided modeling (FEA) and prototype testing to determine the material behaviors in hydroforming process. The objective of this research is to verify the effects of major manufacturing parameters on hydroforming processes. The computational analysis and prototype testing indicate that some factors including applied internal pressure path and compressive axial loading play important roles in hydroforming deformation. Both computer-aided modeling and prototyping experiment show close results which verifies the credibility of this research and analytic methodology.

Abstract

A honeypot is used in the area of computer and Internet security. It is a resource which is intended to be attacked and compromised to gain more information about the attacker and his attack techniques. It can also be used to attract and divert an attacker from the real targets. Compared to an intrusion detection system, honeypots have the big advantage that they do not generate false alerts as all traffic is suspicious, because no productive components are running on the system. Information security is a growing concern today for organizations and individuals alike. This has led to growing interest in more aggressive forms of defence to supplement the existing methods. One of these methods involves the use of honeypots. In computer terminology, a honeypot is a trap set to detect, deflect, or in some manner counteract attempts at unauthorized use of information systems. In this paper, examine types of Honeypots, detection scheme, advantages and disadvantages of honeypots and generations of honeynets.

Abstract

The study of population and economic growth has been the subject of intense debates between the two schools of thought. One relates to pessimistic opinion that population has a negative impact on economic growth while the other is convinced that the effect is positive. Recently, third group argues that the rise in population is neutral on economic growth. However, till date, the issue remains inconclusive. To analyse causality, using 51 years time series data of GDP and population growth, a Granger Causality Test was done and found that population growth causes neither GDP nor vice versa in India.

Abstract

Modeling and simulation of dissolved lead in groundwater influenced by porosity and seepage velocity in homogenous formation has been developed. Porosity influence were considered in the study area as the major role of lead transport, seepage velocity are through the degree of porosity of the soil, this formation characteristics were thoroughly examined, the variables were applied to formulate a system, this system denoted with mathematical tools that developed a governing equation. These equations were derived and it generated a model to monitor the rate of dissolved lead influenced by porosity and seepage velocity in homogenous formation. The developed model was compared with the experimental values from other locations for validation. The model confirmed the fitness of both parameters, the validation of this model implies that the model should be applied to monitor the dissolved lead in the study location. The figures were found to be increasing gradually and rapidly in several locations, these are based on the influence of porosity and seepage velocity. It is recommended that risk assessment should be thoroughly done to reduce the type of pollution in the study area.

Abstract

In this qualitative research study, 10 military wives with children were interviewed. The participants were between the ages of 18 and 45 and had experienced a minimum of two deployments. The information obtained through the interviews answered the research question, “How do military wives with children perceive and describe their experience during their husbands’ multiple deployments?” Each participant identified her experiences raising children in the absence of her husband. Five themes emerged from the research: (a) deployment differences, (b) communication, (c) stability, (d) support networks and (e) spousal relationship. All of the participants in this research study reported being able to adjust in the absence of their husbands. They were also able to focus on the well-being of their children by providing and maintaining stability within the household, in addition to ensuring that the children remained in constant communication with their fathers to provide a sense of connectedness even in their absence. Despite missing their husbands, these participants continued to find the resources and the solutions needed to continue to balance their lives during multiple deployments.

Abstract

The present study describes the development of a theory for the guidance of ergonomic interventions (EI) and evaluation processes with the help of fuzzy approach. The study was carried out at an educational center (EC) with the micro- and macro-ergonomic interventions. The combined results of both interventions have demonstrated the positive effects of these techniques in increasing the productivity and reducing the musculoskeletal disorders (MSDs). So, the overall annual performance of the educational center had a significant rise in terms of lower costs, increased revenue and work expansion with less human force. Analysis of questionnaire data "body mapping" with the fuzzy approach has shown that the surrounding surface and fuzzy numbers’ intervals, belonging to the degree of comfort of the qualitative dimensions, were more in the control population as compared to the treatment ones, which indicates that the index of ergonomic interventions is positive in EC.

Abstract

E-Learning or Edutainment Learning, the word has several meanings, E-Learning can best be defined as the science of learning without using paper printed instructional material. The concept is new, dynamic and robust approach towards learning and is gaining more and more popularity, as the Subject Matter Experts (SME) are using several tools to create E-Learning modules for the learners. Numerous top institutions and distance learning universities have started degree and diploma courses based entirely on E-Learning. Internet is the primary tool of E-Learning through which students connect from across the world. E-Learning is user interactive, easy, and low cost, and can be done 24 hours a day- 7 days a week depending on the convenience of the learner. The future of E-Learning is very bright as it will replace the burden of carrying heavy school bags on the shoulders of school students and also E-Learning is environmental friendly, as it would certainly put a brake on cutting trees for the sake of printing paper based books; also it could now be called as G-Learning (Green Learning).
