Application of time-temperature superposition method in thermal aging life prediction of shipboard cables

The life of shipboard cables will decrease due to the complex aging processes. In terms of the safety perspective, remaining life prediction of the cable is essential to maintain a reliable operation. In this paper, firstly, based on Arrhenius equation, residual life of new styrene-butadiene cable is calculated; result indicates that the degradation rate which changes with time is proportional to thermal temperature. Then second order dynamic model is adopted into the residual life prediction, combined with the time-temperature superposition method(TTSP), and a new residual life model is proposed. According to the accelerated thermal aging experiment data and Arrhenius equation, TTSP method demonstrates to be an efficient way for life prediction, and life at normal temperature can be estimated by this model. In order to monitor the state of styrene-butadiene cable more accurately, an improved residual life model based on equivalent environment temperature of cable is proposed, and life of cable under real operation is analyzed. Result indicates that this model is credible and reliable, and it provides an important theoretical base for residual life of cables.

Inheritance of AFLP markers and genetic linkage analysis in two full-sib families of the marine shrimp Litopenaeus vannamei (Crustacea, Decapoda)

The cultivation of the marine species of shrimp Litopenaeus vannamei has emerged as one of the segments that best develop in the Brazilian aquaculture, representing the agribusiness that grew the most in recent years. Regarding the economic importance of the farming of this species in Brazil, further studies on genetic improvement were conducted. A F2 segregating population consisting of 192 samples for each G1 and G2 families, from crossing inbred lines was used for the studies performed in the present work. The genetic linkage analysis was based on polymorphic markers derived from nine AFLP (Amplified Fragment Length Polymorphism) primers. Fourteen genetic linkage groups including 103 segregating polymorphic markers were constructed covering350 cMfor G1 and four genetic linkage groups including 59 markers were constructed covering300 cMfor G2. Simple marker analyses were performed among individuals evaluated phenotypically, finding markers linked to genes that may be potentially important and useful to assess characteristics of economic importance for traits related to weight and the disease IMN (idiopathic muscle necrosis). The statistical model including markers explained major proportion of phenotypic characteristic weight in relation to disease incidence IMN.
Exploring the effect of workplace spirituality on job embeddedness among higher secondary school teachers in Ernakulam district

Abstract The quality of education is determined by the quality of the teachers. As teachers are entrusted with the responsibility of shaping and guiding the future citizens of a nation, it is essential for them to be involved and committed toward their job. This brings out the importance of retaining teachers in their job. The concept of workplace spirituality (WPS) brings in the very feeling of being connected to the workplace, which, undoubtedly helps them to remain attached to the job. The study tries to understand the relationship between WPS and job embeddedness (JE) among the higher secondary school teachers in Ernakulam District. WPS was measured using the scale adapted from Milliman et al. and JE was measured using the scale developed by Mitchell et al. A sample size of 105 was selected using simple random sampling method. The study found a satisfactorily good level of WPS and JE among the respondents. The result of the study also shows a significant positive relationship between WPS and JE.
Comparison of Water Absorbed Dose for Photons of Linac and Traceability System for Radiotherapy in China

A water calorimeter is developed as the primary standard of the absorbed dose to water for high-energy photon beams from clinical accelerator, aiming to support the dosimetry calibration for radiotherapy in China. The tissue phantom ratio for 6 and 10 MV photon beams were obtained from the direct measurement and the percentage depth-dose curve separately. The absorbed dose to water of high-energy photon beams from clinical accelerator was reproduced by a water calorimeter with the combined standard uncertainty of 0.35%. The results of the BIPM.RI(I). K6 comparison reported as ratios of the NIM and the BIPM evaluations (and with the combined standard uncertainties given in parentheses), are 0.9917(60) at 6 MV, and 0.9941(59) at 10 MV. The quality correction factors KQ of commonly-used chambers were measured directly, which were 0.3%∼0.7% smaller than the recommended data in the IAEA TRS-398 protocol. The variations are between 0.1% and 0.8% for the results based on the methods recommended in IAEA TRS-398 and the chambers calibrated by megavoltage photons, in terms of the absorbed dose to water for the high-energy photon beams from clinical accelerator.

Impact of Energy Price Variability on Global Fertilizer Price: Application of Alternative Volatility Models

This study evaluates the effects of volatility in crude oil and natural gas prices on fertilizer price variations. Specifically, the study looks at the mean and volatility effects of oil and natural gas prices on both mean and volatility changes in fertilizer prices. Both symmetric models [GARCH (1, 1)] and asymmetric models [GJR (1, 1)] were used to model volatility in fertilizer prices and to evaluate the effects of the volatility over different time periods using Bai-Perron structural break tests. The results show that changes in oil and natural gas prices increased fertilizer prices after the crisis period, during June 2007 to June 2008. Both the ARCH and GARCH had significant effects on fertilizer prices, suggesting that the volatility effects of oil and natural gas prices on fertilizer prices were also significant. Furthermore, the maximum impact of higher energy prices depends on triple superphosphate and diammonium phosphate (DAP) leading to higher production costs and consequent increase in total farm expenditures for crop producers. These higher production costs invariably have a negative effect on farm profitability, thus reducing the investment levels in the farm sector.
Improving the Reliability of Skewed Caches through ECCbased Hashes

Skewed caches have been proposed to reduce the miss ratio on a cache by indexing the cache lines of a two way set associative cache not with the index but with a hash function of the index and the tag. This paper proposes to use ECC codes as the hashing functions that allow also correcting the stored data. It is shown that ECC behave very well as hash functions and that ECC protection provides gains in terms of error coverage with respect to state of the art skewed cache approaches.
Toward Identifying the Inventive Templates of New Products: A Channeled Ideation Approach

New product ideation might be improved by identifying and applying certain well-defined schemes derived from an historical analysis of product-based trends, termed “templates. ” These templates might contribute to the understanding and prediction of new product emergence. The authors derive templates in a study that maps the evolution of product changes by adapting a set of intrinsic operations originally designed to uncover hidden logical patterns in technological inventions. They find that the majority of new product versions can be accounted for by as few as five templates. The authors define the five templates and show that they derive from six elementary (first principle) operators. A procedure for using the dominant template, termed “Attribute Dependency,” is outlined, followed by a report of two experiments examining its usefulness in the context of product ideation.
Optimised Proactive Link State Routing For DOS Attack Prevention

: A Mobile Ad hoc Network is a collection of independent mobile nodes that can communicate to each other via radio waves. The mobile nodes that are in radio range of each other can directly communicate, whereas others need the aid of intermediate nodes to route their packets. Each node has a wireless interface to communicate with each other. These networks are fully distributed, and can work at any place without the help of any fixed infrastructure as access points or base stations. Routing protocols are divided into two broad classes – Reactive and Proactive. In Reactive or on demand routing protocols the routes are created only when they are needed. The application of this protocol can be seen in the Dynamic Source Routing Protocol (DSR) and the Ad-hoc On-demand Distance Vector Routing Protocol (AODV). Wherein Proactive or Table-driven routing protocols the nodes keep updating their routing tables by periodical messages. OPSR proposes a proactive mechanism in source routing.
B ased Two-tuple Linguistic Multi-attribute Decision-making on Grey Target Theory

Nowadays, selection of an optimal investment program has become a challenging task for the decision makers in the Electric Power Company. Investment program selection for a company can be viewed as a complicated multi-criteria decision making (MCDM) problem which requires consideration of selection attributes. Moreover, decision makers tend to use multi-granularity linguistic term sets for expressing their assessments because of their different backgrounds and preferences, some of which may be uncertain and incomplete. Therefore, this paper studies the multi-attirbute decision-making problem under two-tuple linguistic environment and proposes a new approach based on grey target theory. A new two-tuple linguistic bull’s-eye is defined and the two-tuple linguistic bull’s-eye related coefficient is derived consequently. Then, a new optimization model is provided by applying maximize deviation principle to determine the attributes weights. The order of alternatives is listed by comparing the two-tuple linguistic bull’s-eye relative related degree. Finally, an example of power communication resources investment illustrates the applicability of the proposed method. Keywords-grey target theory; two-tuple linguistic; multiattribute decisionmaking; attribute weights;bull’s-eye related coefficient

Impact of hypertension home-based care on health related quality of life of Nigerian patients: research concept, framework and methodology

ABSTRACT Background: Public health importance of hypertension have been documented all over the world. In recent years, there has been increase cases of hypertension reported in African countries including Nigeria. The current management strategy of hypertensive cases within hospital setting are characterized by high default rate, non-adherence, poor medical outcomes and poor quality of life. While past studies emphasized use of medical outcomes to assess treatment or intervention outcomes, only scanty studies take into cognizance the quality of life that patients live. Because of the chronicity of hypertension, it is important to begin to assess the Health Related Quality of Life (HRQoL) of patients and begin to use such as an impact assessment of treatment or intervention strategies. This study proposed to develop and implement a home based follow-up care (HBFC) intervention and evaluate the impact of the intervention on the HRQoL of hypertensive patients in Nigeria. Materials and methods: This study will be a randomized control trial (un-blinded) to be conducted in 3 stages. Stage 1 will develop HBFC program while in stage 2, patients will be recruited, assessed (baseline data), randomized into 2 arms of study and follow-up for 6 months. The third stage will evaluate the impact of the intervention on HRQoL and disseminate the findings. Data will be collected with the use of structured questionnaire which will contain validated tools like SF-36v2 for HRQoL and Morisky scale for medication adherence. Main outcome measurement will be treatment effect using HRQoL while data would be analyzed using SPSS, version 22. Intention to treat (ITT) analysis concept will be employed and main hypothesis will be tested using paired t-test analysis. Level of significance will be set at p-value of < 0.05 and 95% confidence intervals (CI). Expected outcome: The study will contribute to the existing knowledge on home based care program for hypertensive patients in developing countries where literature is scanty. It will generally give insight into the importance of HRQoL measurement in interventional studies on hypertension and other related chronic diseases in this setting. Keywords: Hypertension, Health Related Quality of Life, Home-based Care, Research Concept, Framework and Methodology
Assessment of inoculation techniques to evalute apple resistance to Phytophthora cactorum

Two existing direct inoculation techniques (excised stem and intact stem) were used to determine the aggressiveness of 10 isolates of Phytophthora cactorum on apple rootstocks. The susceptibilities of five apple rootstocks were also compared. Wounds were made with a cork borer on excised and intact stems that were inoculated with mycelial discs of the various isolates. Lesion length was used as the criterion by which aggressiveness of isolates as well as susceptibility of rootstocks was quantified. Results showed susceptibility of rootstocks varied according to isolate used. Therefore selection of isolates to determine the susceptibility of apple rootstocks to collar and crown rot is vital. Direct inoculations can only be used as an indication of levels of aggressiveness and susceptibility of rootstocks since they ignore the bark resistance thus only measure the susceptibility of the phloem cambium region to infection.
Aerosol dynamics in the Copenhagen urban plume during regional transport

Abstract. Aerosol particles in the submicrometer size range (PM1) have serious impacts on human health and climate. This work aims at studying the processes relevant for physical particle properties in and downwind Copenhagen and evaluating the capability of a detailed aerosol dynamics and chemistry model (ADCHEM) to describe the submicrometer aerosol dynamics in a complex urbanized region, subjected to a variety of important anthropogenic sources. The study area is the Oresund Region with Copenhagen (about 1.8 million people) as the major city, including the strait separating Denmark and Sweden with intense ship traffic. Modeled aerosol particle number size distributions and NOx concentrations are evaluated against ground-based measurements from two stations in the Copenhagen area in Denmark and one station in southern Sweden. The measured and modeled increments in NOx concentrations from rural background to the urban area showed satisfactory agreement, indicating that the estimated NOx emissions and modeled atmospheric dispersion are reasonable. For three out of five case studies, the modeled particle number concentrations and size distributions are in satisfactory agreement with the measurements at all stations along the trajectories. For the remaining cases the model significantly underestimates the particle number concentration over Copenhagen, but reaches acceptable agreement with the measurements at the downwind background station in Sweden. The major causes for this were identified as being the lack of spatial resolution in the meteorological data in describing boundary layer mixing heights and the uncertainty in the exact air mass trajectory path over Copenhagen. In addition, particle emission factors may also have been too low. It was shown that aerosol dynamics play a minor role from upwind to urban background, but are important 1–2 h downwind the city. Real-world size-resolved traffic number emission factors which take into account the initial ageing in the street canyon can be used to model traffic emissions in urban plume studies.
Antioxidant potential of some agri-horticultural wastes

Free radicals are known inducers of cellular and tissue pathogenesis leading to several human diseases such as cancer, inflammatory disorders, as well as in aging processes. Antioxidants provide protection to living organisms from damage caused by uncontrolled production of reactive oxygen species and the concomitant lipid peroxidation, protein damage and DNA strand breakage. There has been an increased concern over management of agri-horticultural waste to develop useful product and to prevent environment pollution. Some selected agri-horticultural wastes like left over residuals from Trigonella foenum-graecum (Fenugreek), Brassica rapa (Turnip), and Brassica oleracea (Cabbage) were studied for their antioxidant activity alone and in combination to find synergistic effect if any and to determine their nutraceutical potential. The antioxidant activity of residuals of fenugreek, turnip, and cabbage was 816, 864 and 545.6 μmTE/g whereas the antioxidant activity of their synergistic combinations of (fenugreek plus turnip), (fenugreek plus cabbage), (turnip plus cabbage) and all the three (fenugreek plus turnip plus cabbage) was found to be 808, 1140, 2456 and 1048 μmTE/g respectively. The synergy fold was found to be maximum in combination of turnip and cabbage with 3.4 fold. The present studies showed that agri-horticultural wastes have tremendous potential to be used as nutraceutical in the prevention and management of free radicals, oxidative stress and associated disorders.

This study was administrated to 115 participants in Jakarta. Descriptive statistic, correlation analysis and multiple regressions were performed to determine the important factors. The results indicate that intention, voluntariness, observability, water usage and age are positively influence the adoption of the seats in urban households in Jakarta.
A cDNA-AFLP protocol with reciprocally arranged 2-enzyme sequential digestion and silver staining detection

This study provides a modified protocol to the standard cDNA-amplified fragment length polymorphism (AFLP) procedure that has been used to detect differentially expressed transcripts in various systems. Modifications aimed to improve the overall coverage of the technique and the isolation of single fragments from each of the cDNA species. The protocol utilizes oligo-d(T) coupled magnetic beads to isolate and synthesize, and 2-enzyme sequential digestions of ds-cDNA molecules with flip-flop strategy on the beads to release transcript tags representing individual mRNA type and quantity. The protocol has been applied to detect Puccinia sorghi-induced expressional changes in maize leaf material sampled at 8 time points following inoculation. cDNA-AFLP analysis of this material pooled into 2 time intervals (6-24 h and 36-96 h), along with their controls, revealed banding patterns in which 10-20 differentially expressed message tags were present among the 40-80 bands detected per primer combination. Three hundred and ten differentially expressed message tags were sequenced, and the majority with known functions were found to be associated with plant-microbe interactions. Although it requires a few additional steps, this protocol appears to be effective in revealing differentially expressed messages, and the study demonstrates that pooling the material in the preparation of templates and silver staining detection provides economical alternatives for surveying and identifying expressional modulations occurring over relatively longer time periods.
