Kit of Self-Moving Units for Automatic Inspection of Marine Structures and Plants： Low Cost Unit for Inspection of Holds

All vessels and offshore units require regular inspections to prevent structural or functional damages. Periodical inspections are based on classification society’s requirements and include both visual surveys and non-destructive test interventions, to look for structural damage, pitting, corrosion, thickness measurement, usually documented by measurements or images. Different approaches of inspection can be proposed for underwater and for dry areas, using unmanned vehicles or service robots able to improve traditional inspection methods. Several excellent proposals are today available: nevertheless, reasons of costs, operation complexity and impossibility to cover all types of inspection with a unique autonomous unit limit and conditions the applicability of automatic inspection systems. The paper is the first of a series describing the main results of a wide research activity carried out at DREAMS Lab (Laboratory of Drives and Experimental Automation for Marine Systems) of the University of Genoa. The studies are oriented to the realization of a kit of low cost and unsophisticated self-moving units, devoted to support some recursive inspections in dry areas of ships and on offshore plants as bulkheads, holds, double bottoms and ducts. The paper describes the design and prototyping of a pneumatronic unit oriented to inspection and maintenance of ship holds. Conceived to realize a portable and user-friendly tool which could take part of an “inspection kit” for the use of inspectors, able to simplify and speed up the inspection visits with and automatic generation of survey reports.
Frequent Episodes of Brief Ischemia Sensitize the Fetal Sheep Brain to Neuronal Loss and Induce Striatal Injury

ABSTRACT: We examined the neuronal consequences of repeated brief episodes of in utero cerebral hypoxia-ischemia. Chronically instrumented fetal sheep were subjected to three 10-min episodes of reversible cerebral ischemia, repeated at either 1-h (n = 8) or 5-h (n = 5) intervals. Four fetuses were subjected to a single 10-min of ischemia and 17 fetuses to a single 30-min of ischemia. Repeated insults altered the distribution of damage with relatively marked striatal injury compared with isolated episodes of ischemia (p < 0.01). Frequent insults were associated with greater neuronal loss (p < 0.01) and a failure to restore electrocorticographic activity and resolve cortical cytotoxic edema between insults. Intermittent cortical hyper excitability developed after repeated insults irrespective of the interval between insults. These findings emphasize that repeated brief episodes of ischemia alter the distribution of damage and sensitize the fetal brain to neuronal injury, particularly if the episodes are frequent. Striatal damage may be a feature of multiple but not single insults.
Asset management for energy system retrofit

Energy System Retrofit is an important activity for simultaneously improving resource efficiency, economic performance and contribution of industry to sustainability. While identifying thermodynamically and technically feasible options for retrofit-based energy savings is an important necessary step, it is not a sufficient one for achieving real savings. A further necessary step is the selection of a set of economically feasible and attractive ways of implementing the identified retrofit options. This paper provides an analysis of the investment planning concepts as applied to the retrofit of Heat Exchanger Networks (HENs) and identifies the key issues for retrofit implementation and planning. The paper concludes with the formulation of further research goals, aimed at the establishment of an integrated method for optimal planning of retrofit investments in energy systems.
Exploring the application of mission statements on the World Wide Web

Mission statements are considered to be one of the most popular management tools in the world – and also one of the most frustrating. To secure their success, it has been recommended that mission statements be communicated and disseminated to as many internal and external stakeholders as possible. One means for doing this is through the Internet and the posting of an organization’s mission statement on its company Web site. But who is doing this? What types of organizations are using the World Wide Web to advertise their missions? Where is a mission statement typically located in a corporate Web site? And what are some of the motivations that an organization has for posting or not posting its mission? These are questions which have not yet been addressed by previous research and which this preliminary study sought to answer.
External influence on Bitcoin trust network structure

Networks can express how much people trust or distrust each other. Trust between people may be influenced by factors such as relationship, reputation status, experience, stereotypes, media, information and governments between some. Bitcoin trust networks express how much people trust or distrust each other. Trust in Bitcoin trust network may be influenced by external factors like Bitcoin prices or breach of Bitcoin exchanges like Mt. Gox. One of the goals for this project is to find the effect of external influence to changes in the trust network. One hypothesis is that increase in positive external influence would increase the overall trust in the network, while a drop would decrease the trust. The change in prices may also change the network structure, for example, an hypothesis is that a drop in price would make the positive trust clusters turtle-up [1] to support each other. The second goal would be to create a model that can correctly predict the effects of a network property change in Bitcoin’s price.
Testis size matters for genome evolution.

In many primates, females mate with multiple partners, causing an often-intense competition among males to pass along their DNA to be king of the genome as well as the jungle. Alex Wong (2014) used a published sequence data set from 55 species of primates to test for a correlation between molecular evolutionary rates across a genome (substitution rates) and testes weights, used in the study as a proxy for increased sperm production and competition. It is widely thought that the production of increased numbers of sperm results from more rounds of cell division—and with more cell division, more mutations arise during sperm production. “In general, the speed of genome evolution is higher for species in which males have large testes in comparison to species in which males have small testes,” said Wong. “This finding helps us to understand why genomes evolve at different rates in different species, and has implications for our understanding of the relationship between female mate choice and the overall fitness of a population. ” Wong applied a sophisticated evolutionary method to detect a correlation between testes size and substitution rate in primates and found a positive correlation when accounting for other confounding factors. This finding could provide support for the general prediction that sperm competition should result in higher substitution rates as a consequence of higher spermatogenic activity in species that mate with more than one male. “The current finding of covariance between sperm competition intensity and substitution rates adds to a growing body of knowledge concerning the sources of substitution rate variation,” said Wong. “The extent to which this covariance is widespread is not yet clear; application of robust comparative methods to large phylogenetic data sets in other taxa, such as birds and insects, will help to establish its generality. ”
Toxicity detection from EILATox‐Oregon Workshop samples by using kinetic photobacteria measurement: the flash method

The Flash test, which can be used to measure the toxicity from clear, turbid and coloured samples with identical protocol, was used in the EILATox‐Oregon Workshop. During the workshop, 17 synthetic samples and three environmental samples were tested. In the Flash method the photobacteria Vibrio ﬁscheri are initially dispensed on top of the sample and the light output of the bioluminescence reaction is recorded at a rate of several readings per second. The change in the light production was measured at two points: 30 s and 30 min after exposure at room temperature. Toxicity calculations were done by using either the peak height of the sample or the peak height of the control sample (maximum signal at 0–2 s). When the peak height of the sample is used as a reference, the colour and turbidity effect of solid particles are taken into account throughout the whole measurement period. In the EILATox‐Oregon Workshop toxicity was seen in samples 1 (chlordimeform), 4 (phosdrin), 5 (HgCl2), 6 (sodium arsenite), 8 (metham sodium), 12 (p‐chlorophenol), 14 (sodium selenite) and 17 (MNNG). Only samples 1, 4 and 12 showed different ec50 values between different calculations of toxicity. The ec50 values were calculated and compared with the ec50 values of Microtox derived from the literature. The Flash test will not replace the standardized photobacteria test, but is the advanced version of it and is needed when the sample matrix is complex and when speed and low costs are required.

Hemodynamic effects of S-nitrosocysteine, an intravenous regional vasodilator.

BACKGROUND S-nitrosocysteine is a carrier form of nitric oxide that can be delivered intravenously. S-nitrosocysteine is rapidly metabolized by plasma (half-life = 2-3 seconds), forming nitric oxide and cysteine. With its short half-life and potent vasodilatory properties, S-nitrosocysteine may be useful as a pulmonary vasodilating agent in cases of postoperative and chronic pulmonary hypertension. OBJECTIVE Our objective was to determine the hemodynamic properties of S-nitrosocysteine on the pulmonary and systemic circulations to assess its potential utility as a pulmonary vasodilatory agent. METHODS Eleven adult swine were anesthetized. Thermodilution (Swan-Ganz; Baxter International, Inc, Deerfield, Ill) and arterial catheters were inserted. Flow probes were placed around the coronary, renal, superior mesenteric, and iliac arteries. Incremental infusion doses of S-nitrosocysteine (5-80 nmol. kg(-1). min(-1)) were delivered into the right atrium. Cardiac output, right and left heart pressures, heart rate, Pao(2), and iliac, renal, coronary, and mesenteric blood flow rates were recorded at baseline and at each infusion dose of S-nitrosocysteine. RESULTS Low-dose S-nitrosocysteine infusion decreased mean pulmonary artery pressure (15%, P =.013) without a significant reduction in mean systemic artery pressure. Higher dose infusions produced further dose-dependent declines in pulmonary vascular resistance and measurable reductions in systemic vascular resistance (P =.01). At an S-nitrosocysteine dosage of 40 nmol. kg(-1). min(-1), there was a significant reduction in renal (P <.001) and mesenteric (P =.003) blood flow but no change in iliac (P >.2) or coronary (P >.2) blood flow. Cardiac output remained constant up to infusion rates of 40 nmol. kg(-1). min(-1) (P >.2). Doses higher than 5 nmol. kg(-1). min(-1) resulted in a substantial dose-dependent reduction in Pao(2) (P <.001), suggesting dilation of atelectatic areas of the lung. CONCLUSION S-nitrosocysteine is a potent vasodilatory agent capable of overcoming the hypoxic vasoconstrictive response of the lung. Our results suggest it may prove useful as a pulmonary vasodilatory agent at low doses. Higher dose infusions reduce mean systemic pressure and lead to compensatory reductions in renal and mesenteric blood flow without a decrease in cardiac output.
A layered distributed program debugger

Debugging distributed programs is much more difficult than debugging sequential programs. One of the reasons is the communication among programs (processes) which may happen concurrently and nondeterministically. To be able to analyze such communication events is therefore an essential task for any distributed program debugger. The paper describes the design and preliminary implementation of a layered distributed program debugger. The debugger helps a user to locate bugs, to analyze a distributed program and to fix bugs. <<ETX>>
The Influence of Employee Job Satisfaction on Organizational Performance

As banks are an important part of financial well-being of any nation therefore banks need to perform well to do that function well. There is an undoubted relationship between the satisfaction of employees and the performance of organization. This study was conducted with an objective to find that relationship between employee satisfaction and performance of banks. The study was conducted on a sample of 140 bank employees. Pearson’s correlation was used to test the relationship between the two variables, using t-test and the result came out to be positive at 1% level of significance.
Chapter 2 Production Planning and Scheduling : Interaction and Coordination

In many organizations, production planning is part of a hierarchical planning, capacity/resource allocation, scheduling and control framework. The production plan considers resource capacities, time periods, supply and demand over a reasonably long planning horizon at a high level. Its decision then forms the input to the more detailed, shorter-term functions such as scheduling and control at the lower level, which usually have more accurate estimates of supply, demand, and capacity levels. Hence, interaction between production planning and production scheduling/control is inevitable, not only because the scheduling/control decisions are constrained by the planning decisions, but also because disruptions occurring in the execution/control stage (usually after schedule generation) may affect the optimality and/or feasibility of both the plan and the schedule. If the overall performance of the production system is to be improved, disruptions must be managed effectively, with careful consideration of both planning and scheduling decisions. This chapter focuses on the interaction between production planning and scheduling, emphasizing the coordination of decisions, with special emphasis on making robust decisions at both levels in the face of unexpected disruptions. We provide examples and realistic scenarios from semiconductor manufacturing. To capture the interaction between production planning and scheduling, we suggest an intermediate model between the two levels. One can view this as a lowerlevel planning model or a higher-level scheduling model, but ultimately it provides a middle ground between the two levels of the decision-making framework. In many systems, the longer-term, aggregated production plan is used to facilitate scheduling. This is usually achieved by creating specific work orders or jobs of different product types that collectively resemble the output required by the production plan and generating a release schedule for the jobs. For example, semiconductor manufacturers
Integrating Green and Gray: Creating Next Generation Infrastructure

Traditional infrastructure systems worldwide rely on built solutions to support the smooth and safe functioning of societies. in the face of multiplying environmental threats, this approach alone can no longer provide the climate resiliency and level of services required in the 21st century. Natural systems such as forests, floodplains, and soils can contribute to clean, reliable water supply and protect against floods and drought. In many circumstances, combining this “green infrastructure” with traditional “gray infrastructure,” such as dams, levees, reservoirs, treatment systems, and pipes, can enhance system performance, boost resilience, lower costs, and better protect communities. Service providers such as water utilities, flood management agencies, irrigation agencies, and hydropower companies can deliver more cost-effective and resilient services by integrating green infrastructure into their plans. However, to guide its appropriate use in mainstream infrastructure programs, green infrastructure must be as rigorously evaluated and carefully designed as gray projects. This report guides developing country service providers and their partners on how to seize this opportunity. It offers service providers a framework to evaluate green infrastructure from a technical, environmental, social, and economic perspective, and to assess key enabling conditions, with illustrative examples. It also provides guidance for policymakers and development partners, who must set the incentives and enabling conditions to mainstream solutions that unite green and gray infrastructure.
Facts on fats

Cardiovascular disease and age‐related macular degeneration (AMD) may share common risk factors in their causal pathways. Decades of research from the cardiovascular sciences on fats have led investigators to focus on specific types of fats rather than total fat as a whole. They have established that saturated and trans‐unsaturated fats (trans fats) are damaging to cardiovascular health while polyunsaturated fats, particularly the marine omega 3 fatty acids appear protective. This has led to a number of studies investigating the associations of fat and AMD. Though the causal relationship between fats and AMD remain unproven, some studies suggest that an association may be present. To be able to understand and interpret the study results and their implications, an understanding of the fats in the diet is important. This review aims to give an overview of fatty acids, particularly the trans‐unsaturated fatty acids, and the relevant food groups.
The Utility of Administrative Data for Measuring Adherence to Cancer Surveillance Care Guidelines

Background:Adherence to professional society guidelines for follow-up or surveillance care in cancer survivors usually is measured with medical record review. Administrative data represent an alternative approach that may encompass larger numbers of patients with relatively low incremental costs. Objectives:We sought to determine the feasibility of using claims data to measure guideline adherence. Methods:By reviewing paper and electronic medical records and claims data of 429 patients with 1 of 5 common cancers who received treatment with curative intent, we compared specific procedure receipt as well as guideline adherence classification as derived from claims and medical record data. Concordance was measured via kappa statistics. Measures:Care in the initial 18-month follow-up period was characterized as less than recommended, recommended, or greater than recommended per practice guidelines in both medical record and administrative data. Results:Matching rates for individual procedures varied and were generally highest for certain laboratory tests and lowest for physical examinations. There were generally good-to-excellent levels of agreement (kappa = 0.34–0.96) between a patient's classification in claims data and medical record data. No consistent differences in agreement were observed according to insurance type. Conclusions:In general, claims data capturing procedures and visit use for characterizing guideline adherence was comparable with what was documented in the medical record and suggests that if validated in other settings, administrative data could be used to describe patterns of follow up care.
Separation of Chromosome Termini during Sporulation of Bacillus subtilis Depends on SpoIIIE

ABSTRACT Bacillus subtilis undergoes a highly distinctive division during spore formation. It yields two unequal cells, the mother cell and the prespore, and septum formation is completed before the origin-distal 70% of the chromosome has entered the smaller prespore. The mother cell subsequently engulfs the prespore. Two different probes were used to study the behavior of the terminus (ter) region of the chromosome during spore formation. Only one ter region was observed at the time of sporulation division. A second ter region, indicative of chromosome separation, was not distinguishable until engulfment was nearing completion, when one was in the mother cell and the other in the prespore. Separation of the two ter regions depended on the DNA translocase SpoIIIE. It is concluded that SpoIIIE is required during spore formation for chromosome separation as well as for translocation; SpoIIIE is not required for separation during vegetative growth.

Analysis and prediction of the effect of uncertain boundary values in modeling a metabolic pathway.

The integration of large quantities of biological information into mathematical models of cell metabolism provides a way for quantitatively evaluating the effect of parameter changes on simultaneous, coupled, and, often, counteracting processes. From a practical point of view, the validity of the model's predictions would critically depend on its quality. Among others, one of the critical steps that may compromise this quality is to decide which are the boundaries of the model. That is, we must decide which metabolites are assumed to be constants, and which fluxes are considered to be the inputs and outputs of the system. In this article, we analyze the effect of the experimental uncertainty on these variables on the system's characterization. Using a previously defined model of glucose fermentation in Saccharomyces cerevisiae, we characterize the effect of the uncertainty on some key variables commonly considered to be constants in many models of glucose metabolism, i.e., the intracellular pH and the pool of nucleotides. Without considering if this variability corresponds to a possible true physiological phenomenon, the goal of this article is to illustrate how this uncertainty may result in an important variability in the systemic responses predicted by the model. To characterize this variability, we analyze the utility and limitations of computing the sensitivities of logarithmic-gains (control coefficients) to the boundary parameters. With the exception of some special cases, our analysis shows that these sensitivities are good indicators of the dependence of the model systemic behavior on the parameters of interest.
