The desorption characteristics of lead in two variable charge soils (one developed from Arenaceous rock (RAR) and the other derived from Quaternary red earths (REQ)) were studied, and the effects of pH value, organic acid, and competitive ions were examined. Desorption of Pb(2+) decreased from nearly 100.0 to 20.0% within pH 1.0-4.0 in both soils, and then the decrease diminished at pH > 4.0. O...

The widespread use of Mobile Ad Hoc Networks (MANETs) in many fields of applications has led to the continuous development of routing protocols which can perform well when deployed under different scenarios, as well as offer better Quality of Service (QoS) support. In this paper, we focus on how link stability is utilized as a metric to provide accurate feedback on the network. We then introduc...

IEEE 802.16e has received wide attention as it supports high data rates and incredible pervasive connectivity with high Quality of Service (QoS) capabilities. To support QoS, many Bandwidth REQuest (BW-REQ) mechanisms are suggested in the literature for resource reservation in mobile WiMAX networks. There are chances for performance degradation with increase in the number of requests. QoS can b...

Steam injection for power and efficiency augmentation in aeroderivative gas turbines has been commercially established for natural gas-fired cogeneration since 1980. Steam-injected gas turbines fired with coal and biomass are being developed. A performance and economic assessment of biomass integratedgasifier steam-injected gas turbine (BIGISTIG) cogeneration systems is carried out here. A deta...

Bound sialic acids on rat spermatozoa were assayed by oxidation with 1 mMNaIO4 at 0\s=deg\C,liberating C-9 as formaldehyde which was further quantitated using 3\x=req-\ methyl-2-benzothiazolinone. The mean \m=+-\s.d. (n = 20) content of bound sialic acids of spermatozoa from the caput and cauda epididymidis was 50\m=.\9 \m=+-\8\m=.\0and 25\m=.\2 \m=+-\3\m=.\8 nmol/108 spermatozoa respectively. ...

Predictive models, such as rule based classifiers, often have difficulty with incomplete data (e.g., erroneous/ missing values). So, this work presents a technique used to reduce the severity of the effects of missing data on the performance of rule base classifiers using divisive data clustering. The Clustering Rule based Approach (CRA) clusters the original training data and builds a separate...

The change of natural ionizing radiation and the radon exhalation rates from typical building materials in underground parking lots are presented article. activity concentration radionuclides 232Th, 226Ra, 40K six important types construction materials, which mostly used Lithuania, were analyzed using high-resolution gamma spectroscopy. highest values found concrete ferroconcrete samples: 226Ra...

Weighted Probability Distribution Voting (WPDV) is a newly designed machine learning algorithm, for which research is currently aimed at the determination of good weighting schemes. This paper describes a simple yet eeective weight determination procedure, which leads to models that can produce competitive results for a number of NLP classiication tasks. 1 The WPDV algorithm Weighted Probabilit...
