This research paper explains the results of the prediction analysis of the number of lives lost in the event of a catastrophic dam collapse in Indonesia as a further consideration in assessing the level of risk of dam safety. The proposed procedure is to make a new prediction index of the number of lives lost (LoL) as the development of a risk index of evacuation requirements from Risk Affected Populations (PENRIS), on the Modified ICOLD Method which is always used in Indonesia. This study, resulting in a regression equation as a correlation between PENRIS and LoL, takes its source from various catastrophic dam collapse events that have occurred in the world including Indonesia. Furthermore the regression equation is integrated with the standard determination of the level of risk of dam safety used in Indonesia and the world, for conditions with and without a disaster early warning system based on the Graham formula (2010). Further analysis of the Emergency Action Plan (EAP or RTD) of 16 dams in Indonesia as a sample, gives an indication that the implementation of an early warning system will reduce the amount of LoL by almost 100% if implemented according to design. This research, with its focus on developing a prediction index for the number of LoL, proves that in Indonesia, where there are still many dams eventhough they already have RTDs, and have not conducted a disaster-based space arrangement based on predicted LoL numbers,the reduction in the value of dam security risks can only be optimal in the range of 50 % of the total dam studied.

In this work, the application of a feed-forward artificial neural network (FFANN) in predicting the degree of polymerization (DP) and loss of life (LOL) in oil-submerged transformers by using the solid insulation evaluation method is presented. The solid insulation evaluation method is a reliable technique to assess and predict the DP and LOL as it furnishes bountiful information in examining the transformer condition. Herein, two FFANN models are proposed. The first model is based on predicting the DP when only the 2-Furaldehyde (2FAL) concentration measured from oil samples is available for new and existing transformers. The second FFANN model proposed is based on predicting the transformer LOL when the 2FAL and DP are available to the utility owner, typically for the transformer operating at a site where un-tanking the unit is a daunting and unfeasible task. The development encompasses constructing numerous FFANN designs and picking networks with superlative performance. The training and testing procedures databank is based on the dataset of the 2FAL and DP from a fleet of transformers and measured from laboratory analysis. The correlation coefficient of 0.964 was ascertained when the DP was predicted using the 2FAL measured in oil. In the FFANN model, a correlation coefficient of 0.999 against the practical data where one can make a reliable prediction of transformer LOL concerning 2FAL was generated and the amount of DP present produced. This model can be used to predict the DP and LOL of new and existing transformers at the manufacturer’s premises and operating in the field, respectively. To the knowledge of the authors, no research work has been published addressing the methods proposed in this work.

This paper proposes a Home Energy Management System (HEMS) that optimizes the load demand and distributed energy resources. The optimal demand/generation profile is presented while considering utility price signal, customer satisfaction, and distribution transformer condition. The electricity home demand considers electric vehicles (EVs), Battery Energy Storage Systems (BESSs), and all types of non-shiftable, shiftable, and controllable appliances. Furthermore, PV-based renewable energy resources, EVs, and BESSs are utilized as sources of generated power during specific time intervals. In this model, customers can only perform Demand Response (DR) actions with contracts with utility operators. A multi-objective demand/generation response is proposed to optimize the scheduling of various loads/supplies based on the pricing schemes. The customers’ behavior comfort level and a degradation cost that reflects the distribution transformer Loss-of-Life (LoL) are integrated into the multi-objective optimization problem. Simulation results demonstrate the mutual benefits that the proposed HEMS provides to customers and utility operators by minimizing electricity costs while meeting customer comfort needs and minimizing transformer LoL to enhance operators’ assets. The results show that the electricity operation cost and demand peak are reduced by 31% and 18%, respectively, along with transformer LoL % which is reduced by 28% compared with the case when no DR was applied.

Abstract Access to effective communication is critical to the conversations that occur at end-of-life and represents an unaddressed need within palliative care. These challenges may disproportionately affect persons with dementia (PWD). Hearing loss is one of the most common comorbidities among PWD and is independently associated with neuropsychiatric symptoms. However, relatively little is known about the potential impact of hearing loss on PWD at end-of-life. We examined last month of life (LML) data from 971 proxies of deceased PWD from the National Health and Aging Trends Study (2011-2020). Hearing difficulty was associated with increased anxiety/sadness in PWD, χ2(1)=4.596, p=.032, such that 65.6% of persons with hearing difficulty reported anxiety/sadness in the LML. Binary logistic regression found that hearing difficulty was significantly associated with increased anxiety/sadness (OR=1.40, 95% C.I. 1.00 – 1.80, p < 0.05). Interventions that optimize communication for PWD may be a meaningful approach to improving the end-of-life experience.

AbstractWith the development of image recognition technology, face, body shape, and other factors have been widely used as identification labels, which provide a lot of convenience for our daily life. However, image recognition has much higher requirements for image conditions than traditional identification methods like a password. Therefore, image enhancement plays an important role in the process of image analysis for images with noise, among which the image of low-light is the top priority of our research. In this paper, a low-light image enhancement method based on the enhanced network module optimized Generative Adversarial Networks(GAN) is proposed. The proposed method first applied the enhancement network to input the image into the generator to generate a similar image in the new space, Then constructed a loss function and minimized it to train the discriminator, which is used to compare the image generated by the generator with the real image. We implemented the proposed method on two image datasets (DPED, LOL), and compared it with both the traditional image enhancement method and the deep learning approach. Experiments showed that our proposed network enhanced images have higher PNSR and SSIM, the overall perception of relatively good quality, demonstrating the effectiveness of the method in the aspect of low illumination image enhancement.

The Neonatal weight loss is a common problem which most physicians who take care of newborns should recognise. The most common reason is insufficient dietary intake. However the reason can also be an underlying disease. Aldosterone insufficiency in neonates is a rare disease and if not treated correctly can be life threatening. It presents with serious electrolytes abnormalities and metabolic acidosis. It is therefore important to distinguish between serious and benign causes of weight loss in neonates.

Abstract Background Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm with an incidence of 1-1.5 cases per 100,000 adults, accounting for ∼ 15-20 % of newly diagnosed patients with myeloid leukemia in adults. Treatment for CML has changed dramatically with the introduction of imatinib mesylate (IM), the first tyrosine kinase inhibitor (TKI) targeting the BCR-ABL1 oncoprotein. Previous population-based research (Björkholm et al. JCO, 2011) showed a major improvement in outcome of patients with CML up to 79 years of age diagnosed from 2001 to 2008. The elderly still had poorer outcome, partly because of a limited use of IM. However, increasing recognition of IM resistance and intolerance has led to the development of additional (second and third-generation) TKIs, which have demonstrated effectiveness as salvage therapies or alternative first-line treatments. Here we quantify how the life years lost due to a diagnosis of CML has changed between 1973 and 2013 using a measure called the loss in expectation of life (LEL). Methods This population-based study included3,684CML patients diagnosed in Sweden between 1973 and 2013; diagnoses were obtained from the Swedish Cancer Registry. The LEL was estimated using flexible parametric models. The LEL is the difference between the life expectancy in the diseased population and that in a matched subset of the general population. This measure has a simple interpretation as the number of life years lost, or the reduction in the life expectancy, due to a diagnosis of cancer. Results The life expectancy increased dramatically between 1990 and 2013 for CML patients of all ages; see figure. Patients in 2013, on average, lose less than 3 life years due to their diagnosis of CML. The largest increase in the life expectancy and thus the largest decrease in LEL over time was seen in younger patients; a diagnosis of CML in 1990 for a male 55-year old, on average, reduced his life expectancy by approximately 20.6 (95% CI: 20.3-21.1) years whereas a diagnosis in 2010 in the same male would on average reduce his life expectancy by only 2.6 (95% CI: 1.4-3.8) years. Although the greatest improvements were seen in those diagnosed at a younger age, those diagnosed at 85 years still benefitted in better survival over year of diagnosis; a diagnosis of CML in 1990 for a 85-year old, on average, reduced his life expectancy by approximately 3.6 (95% CI: 3.5-3.8) years whereas a diagnosis in 2010 in the same male would on average reduce his life expectancy by only 1.6 (95% CI: 1.0-2.2) years. Conclusions The reduction in life expectancy, or the number of life years lost due to a diagnosis of CML has greatly reduced over the years Patients who are diagnosed at a younger age lose dramatically fewer years in the most recent calendar years compared to previous years due to their CML diagnosis. Improvements in survival in the late 1990s were at least as great as those from 2001 in the youngest patients. Increased number of allogeneic stem cell transplantations, the introduction of interferon-alpha, improved supportive care and second line treatment with IM have all contributed. Less improvement was seen in the older patients which is probably explained by the relatively slow implementation of IM in this patient group. The impact of second generation TKIs on long-term survival remains to be determined. Figure 1.

This article reports on the sampling and recruitment challenges, as well as the strategies used to address them in the Living After Loss (LAL) project, a bereavement intervention study conducted in Salt Lake City and San Francisco comparing two 14-week group conditions with follow-up. We encountered three major challenges: 1) difficulty determining eligibility for some potential participants who were contacted, 2) locating and recruiting nonwhites, and 3) unavailable phone numbers for approximately one-third of those we attempted to contact. Despite these challenges, we achieved a 42% response rate with a sample size of 328 participants comprising 15% non-white. Eighty-five percent of the participants completed all of the follow-up data points. Leading factors in participants' decisions to join and remain in the study were 1) opportunities to obtain help and support, 2) to potentially help other bereaved individuals, 3) to contribute to research, and 4) their on-going interactions with a professional, empathetic, and culturally sensitive project staff. Effectively focusing recruitment efforts and carefully and systematically training research staff were among the most effective strategies we employed and therefore suggest for those planning similar investigations.

Background: Obesity has become a major health issue in the world over past two decades. . This leads us to the need of immense exploration of life style modification options, dietary supplementation and weight loss friendly elements. Aim: Our study aims to highlight the comparative analysis of independent supplementation of vitamin E and iron to young adult females for their weight loss regime. Methods: 90 young adult non pregnant females of age between 25-39 years with BMI ranging between 30-34.9 (obese) were asked to take a fixed 1500 calorie diet for two months. They were divided into three groups with no supplement group, vitamin E group and iron group. Body mass index(BMI), LDL levels and prevalence of fatty liver was assessed among all individuals. Results: vitamin E and iron supplementation reduced BMI in their respective groups. Vitamin e and iron supplementation also reduce the prevalence of fatty liver among groups. Vitamin E reduces serum LDL levels. Conclusion: vitamin E and iron supplementation helps in weight loss. Keywords: obesity, vitamin E, iron, weight loss

Introduction and Aims: Homozygous-familial hypercholesterolemia (Ho-FH) is a rare condition due to biallelic mutations in low-density lipoprotein-receptor (LDL-R) genes characterized by high level of LDL-cholesterol (LDL-c) and huge risk of premature atherosclerotic cardiovascular disease (ASCVD), determining low quality of life and life expectancy. Lomitapide represents a therapeutic option for Ho-FH, but caution should be observed when used in fatty liver disease (FLD) and hypertransaminasemia since it is associated with onset/worsening of liver steatosis. We present a case of safe lomitapide therapy in an adult Ho-FH patient with pre-existing FLD. Case presentation: A 39-year-old man with severe hypercholesterolemia since childhood (LDL-c 405 mg/dl) and premature coronary heart disease history, was referred to our Modena Lipid Clinic. He presented an overt metabolic syndrome, FLD with hypertransaminasemia and elastosonographic significant liver fibrosis. Lipid-lowering-therapy (LLT) included rosuvastatin 20 mg, ezetimibe and evolocumab 140 mg twice a month without reaching LDL-c goal. Genetic analysis revealed homozygous pathogenic LDL-R gene mutation. Evolocumab was increased up to 420 mg twice a month and LDL-apheresis was started with quality of life worsening. Therefore, lomitapide 5 mg daily and low-fat diet were started, obtaining weight loss and lipid profile improvement. However, liver enzymes elevation higher than 5-fold was observed, leading to lomitapide discontinuation and baseline liver enzymes values restoration. After one-month wash-out, lomitapide was gradually reintroduced up to 5 mg daily without significant hypertransaminasemia recurrence, leading to LDL-c target achievement and LDL-apheresis discontinuation. Adherence to low-fat diet and weight loss resulted in FLD and fibrosis improvement. Conclusion: Ho-FH requires complex, combined treatment. Metabolic comorbidities co-existence makes Ho-FH management more difficult. Lomitapide can be safely used in Ho-FH patients with FLD and hypertransaminasemia, but strict follow-up of liver disease and a multidisciplinary approach are needed. Before lomitapide introduction, low-fat diet should be started advantageously and weight stabilization should be obtained.

Streszczenie:

Estuaries are dynamic environments that are strongly affected by natural variability, as well as direct and indirect anthropogenic impacts. A better understanding of the drivers of carbon fluxes and biogeochemical variability in estuarine systems is needed, particularly with the increasing threat of ocean acidification. Morro Bay in Central California is a small nationally protected estuary, with seasonally low freshwater inputs. Since 2007, the bay has experienced a significant loss of native seagrass, Zostera marina, which is an important component of the marine ecosystem. Because seagrass photosynthesis decreases carbon dioxide and increases oxygen in the water column, the loss of seagrass has the potential to substantially change short-term carbonate chemistry and long-term carbon fluxes of an estuary. The spatial variability of carbonate chemistry was measured in Morro Bay using ship-board surveys during the low-inflow summer season and measured the temporal variability by collecting samples close to the shore from July to November. Discrete samples show an increase in total alkalinity and dissolved inorganic carbon in the mid and back bay regions, historically dominated by seagrass. Slightly lower total alkalinity and dissolved inorganic carbon were observed in the Fall season compared to the low-inflow Summer season. Analysis of the relative modification of alkalinity and dissolved inorganic carbon, paired with salinity and temperature data, contributes to an understanding of the drivers of the observed carbonate variability. This understanding may provide clues to the causes and effects of observed changes to the bay with seagrass loss. More broadly, it will inform the vulnerability of other low-inflow estuaries to future acidification and highlight the role seagrasses play in mitigating local acidification.

Probably the most frequently used definition of reinsurance is insurance for insurance companies, by reinsurance the cedant (insurance company) cedes part of the risk to the reinsurer. Reinsurance plays nowadays a crucial role in insurance industry as it does not only reduce the reinsured's exposure, but it can also significantly reduce the required solvency capital. In past few decades various approaches to reinsurance actuarial modelling were published and many actuaries are nowadays just reinsurance specialized. The thesis provides an overview of the actuarial aspects of modelling a non-life per risk and for motor third party liability per event excess of loss reinsurance structure, according to the author's knowledge no study of such wide scope exists and various aspects have to be found in various fragmented articles published worldwide. The thesis is based on recent industry literature describing latest trends and methodologies used, the theory is compared with the praxis as the author has working experience from underwriting at CEE reinsurer and actuarial reinsurance modelling at global reinsurance broker. The sequence of topics which are dealt corresponds to sequence of the steps taken by actuary modelling reinsurance and each step is discussed in detail. Starting with data preparation and besides loss inflation, more individual claims development methods are introduced and own probabilistic model is constructed. Further, burning cost analysis and probabilistic rating focused on heavy tailed distributions are discussed. A special attention is given to exposure rating which is not commonly known discipline among actuaries outside of reinsurance industry and different methodologies for property and casualty exposure modelling are introduced including many best practice suggestions. All main approaches to the reinsurance modelling are also illustrated on either real or realistically looking data, similar to those provided by European insurance companies to their reinsurers during renewal periods.

" Estimating Life Loss for Dam Safety Risk Assessment" explores the need for a new life-loss model in dam safety risk assessment, historical foundations on which that model can be built, and issues that are critical for a successful life-loss model to address. After critiquing existing life-loss models, the work presents a summary of historical insights that were derived by characterizing flood events on the level of subpopulations at risk, using nearly l 00 carefully defined variables. Building upon both conceptual and historical insights, the work culminates by presenting the conceptual basis for a new life-loss model that remains under development. Chapter I introduces the topic of dam safety risk assessment and the central role that life-loss estimation plays in that field. Chapter II discusses important preliminary considerations in model development. Chapter Ill provides a detailed review of previous life-loss models that pertained to floods, including a critique of each. Chapter IV explores the DeKay-McClelland model in detail and raises serious concerns regarding its future use. Chapter V defines nearly l 00 variables and their respective categories for use in characterizing flood events. Chapter VI provides a detailed outline of historical insights that relate to flood events in one of 18 logical categories. Chapter VII proposes the framework for a new conceptual life-loss model-a model that is still under development and has yet to be refined or offered for testing-with sufficient details to indicate how it was developed and how it might be used. Chapter VIII provides a summary, conclusions, and recommendations for future research. Appendices A through D provide material related to over 900 pages of unpublished working documents developed while characterizing 38 flood events and nearly 200 subpopulations at risk. Appendix E offers a summary of existing software that, given additional development, might prove useful to life-loss estimation in dam safety risk assessment.

Normative ideas of age and stage-based transitions are built into policies and practices related to aging. However, how the issues of loss and depression impact older people's experiences of transition are often less prevalent. This paper discusses the sub-theme of loss identified within data from the Late Life Transitions Project; a SSHRC funded research project. In this thesis, qualitative interviews were analyzed from 30 community-residing seniors from diverse social backgrounds. Focused exploration of the everyday ways in which older people discussed major transitions and turning points revealed a strong subtheme of loss. Findings presented are related to the types of loss, the various barriers to integrating loss, coping mechanisms and the impact of social location on loss. Such discussions inform understandings of the ways in which older people discuss and make sense of their loss, and may provide guidance to plan interventions that are more relevant to older people's late life experiences.

Streszczenie:

Catastrophic events such as dam failures or severe floods are considered to be of low probability, although their consequences can be extremely high and might include loss of life. Earlier studies have linked circumstances surrounding historical darn failure events to actual loss of life and produced formulations using statistical analysis of these events. Shortcomings of these methods include the inability to adjust life-loss estimates based on the type of darn failure, global averaging of population at risk, and ignoring the dynamics of the evacuation process. The main objective of this research is to develop a practical and improved life-loss estimation approach for use in dam safety risk assessment and emergency planning. The methodology is specifically formulated to overcome the limitations of previous. purely empirical, approaches. The approach takes into account the spatial and temporal distribution of flood water depth and velocity, fate of buildings, simulation of warning diffusion, and tracking the movement of people from their original location towards safe shelters. The model created, called LlFESim, is designed to serve multiple function s. First, it can be used in a Deterministic Mode using best estimate inputs to obtain point estimates, or to test different policies for evacuation as well as different times of the day and for different dam breach flooding scenarios. Second, the Uncertainty Mode represents input and parameter uncertainties to provide estimates of life loss, and other variables relating to warning and evacuation effectiveness, as probability distributions. These distributions of life loss can be combined with estimates of the uncertainties in other risk assessment inputs, to obtain estimates of uncertainties in risk assessment results, including evaluations against tolerable risk guidelines. Two communities were used to demonstrate the model performance. Deterministic Mode results display the various possible model outputs. Sensitivity analysis for the Deterministic Mode shows that the effect of warning issuance time is the dominant factor in the estimated life loss. However, other factors play an important role such as the time of day, effectiveness of the warning system, and shelter location. Uncertainty Mode results demonstrate the effect of uncertainties in model parameters and inputs on the model results.

AbstractThe Namib Desert, as represented in Iona National Park, provides a living museum of the adaptations of animals and plants to extreme environments. This chapter illustrates the morphological, behavioural and physiological adaptations resulting from natural selection in response to extreme conditions of aridity and temperature. The role of water is described as the ‘currency of life’ in the Namib. Surface area to volume ratios in animals and plants determine rates of water loss through evaporation, with many succulent plant species displaying the short, stout water conserving pachycaul life form. Water capture from fog is achieved by ‘fog basking’ and ‘sand trenching’ by beetle species, and by grazing at night (when water content of grasses is highest) by antelope. Competition for food in low productivity environments such as the Namib takes many forms, including habitat partitioning, cooperative behaviour and efficient food storage mechanisms. Unique Namib natural phenomena, such as the ‘fairy circles’ - bare patches in extensive desert grasslands - have received intensive study by multiple research groups. Arguments proposing divergent hypotheses demonstrate the scientific method in action.

Cargo loss/damage is a very common problem faced by almost any business with a supply chain arm, leading to major problems like revenue loss and reputation tarnishing. This problem can be solved by employing an asset and impact tracking solution. This would be more practical and effective for high-cost cargo in comparison to low-cost cargo due to the high costs associated with the sensors and overall solution. In this study, we propose a low-cost solution architecture that is scalable, user-friendly, easy to adopt and is viable for a large range of cargo and logistics systems. Taking inspiration from a real-life use case we solved for a client, we also provide insights into the architecture as well as the design decisions that make this a reality.

Abstract Downhole casing corrosion monitoring is a key element in production engineering as it ensures the integrity and safety of assets, maximizes the life and serviceability of a well, and contributes to a successful HSE management programs. Consequently, wells are frequently logged for corrosion and metal loss anomalies to monitor casing integrity. This study explores a method using geospatial analytical techniques to develop synthetic corrosion logs to optimize OPEX, supplement missing logs, and avoid production deferment and downtimes. The proposed method generates full synthetic corrosion logs using geospatial analysis based on available logs, then it maps metal loss defects across the entire field. The spatial mapping builds a 3D map based on depth using computational geometry and computer-aided engineering. Hundreds of thousands of data points from hundreds of logs, represented by (1) depth, (2) casing specifications, (3) cement properties, and (4) metal loss severity, have been fed into the framework to develop a variogram model using Kriging interpolation. By developing the variogram model, a map is generated at each depth point with casing metal loss ratio, and hence a full synthetic corrosion log is built. The data set of available corrosion logs was split into two parts; 70% for training the model and the remining 30 % for testing. Then a cross-verification check was done as well. The developed geospatial analytical model achieved an overall confidence level of 95% of all predicted logs generated using the geospatial analysis. Another scenario was initially studied that incorporates depth, metal loss percentages, and well age as the only input data points. However, this study yielded a lower accuracy level of only 90%. This percentage increased to 95% when incorporating formation characteristics, casing and cement properties into the model. The developed model enabled effective optimization of 1000 corrosion logs requirement through the generation of a full field metal loss severity map. The cost avoidance can be estimated to reach up to tens of millions of dollars due to the ability of predicting metal loss for critical wells without actual operation costs. On top of assuring well integrity, the developed method promotes health and safety of assets and personnel as it minimizes physical exposure of corrosive gases such as H2S.

The subject of the research in this paper is to achieve longer and more reliable loss of lubrication (LoL) performance. The research developed the computational thermal analysis model including airflow inside and outside transmissions to predict thermal behavior under LoL. And the research conducted the LoL performance test using the modified BK117D2 (EC145T2) main transmission optimally designed with the computational analysis. Data measurement during the test included temperatures of rotating components such as gears and bearings, temperature distribution on the gear teeth, and airflow speeds and heat fluxes around the transmission in order to analysis the test result. The test procedure was according to the EASA new rule, which has severer test condition than the past rule. The test result shows longer LoL performance than the past test of the BK117D2 main transmission. And the computational analysis model was validated with the measured data. Then, the failure cause and possible future improvements were investigated based on the measured data and the analysis model. Finally the research concluded the modifications on the transmission, the computational analysis model and the measured data are able to make LoL performance longer and more reliable.

Abstract The susceptibility of 316L-type austenite stainless steel to hydrogen was quantified by means of SSRT results and low-cycle fatigue life measurement. Both tests were conducted in the air condition after being charged with high-pressure hydrogen gas of 10 MPa and a temperature of 300°C for 120 hours. In addition, SSRT tests in gaseous hydrogen at a pressure of 10 MPa were also performed and compared to the tests conducted in hydrogen pre-charged and as-received conditions. The 0.2% yield strength and tensile strength did not show there to be a considerable difference between hydrogen pre-charging and the as-received conditions, whereas the gaseous hydrogen condition revealed a remarkable degradation in tensile properties, especially in terms of fracture elongation. In the case of fatigue life test, a considerable influence of hydrogen pre-charging in fatigue life properties was observed in the high strain amplitude regime whereas the measured values in the low strain deformation region are consistently comparable to that in the as-received condition. Fatigue limit was not affected by hydrogen pre-charging.

Abstract Creep and corrosion are typical damage mechanisms of pressure components operated at high temperatures and they are frequently evaluated using the relevant sections of the API 579-1 [1] standard. When a general or local metal loss is expected or assessed via Non-Destructive-Examination (NDE) on a pressure equipment in the creep regime, the time-dependent corrosive phenomenon has a direct impact on the time and stress-dependent creep residual life and the two damage mechanisms are competing and reinforcing one another. For these cases, an API 579-1 Level 3 creep assessment shall necessarily take into account the metal loss induced by the corrosive environment to be effective in predicting the component residual life. In this work, the impact of corrosion on the creep life evaluated according to API 579-1 and the Larson-Miller theory was evaluated for the special case of a low-alloy piping component exposed to both general and local metal loss with variable corrosion and creep rates. A finite-element model was set-up incorporating the inelastic steady-state creep law, the API 579-1 time-fraction creep damage and the progressive metal loss due to uniform and localized corrosion. A parametric analysis was finally carried out to investigate the role of the corrosion rate, and the related, augmented stress field on the overall API 579-1 creep damage.

A life prediction method for combustion turbine blade coatings has been developed by modeling coating degradation mechanisms including oxidation, spallation, and aluminum loss due to inward diffusion. Using this model, the influence of cycle time on coating life is predicted for GTD-111 coated with an MCrAlY, PtAl, or aluminide coating. The results are used to construct a coating life diagram that depicts failure and safe regions for the coating in a log-log plot of number of startup cycles versus cycle time. The regime where failure by oxidation, spallation, and inward diffusion dominates is identified and delineated from that dominated by oxidation and inward diffusion only. A procedure for predicting the remaining life of a coating is developed. The utility of the coating life diagram for predicting the failure and useful life of MCrAlY, aluminide, or PtAl coatings on the GTD-111 substrate is illustrated and compared against experimental data.

Nuclear plant service water systems are a critical part of the facility’s infrastructure. System integrity and performance are vital for plant reliability and essential to achieving a plant life of 40 years and beyond. Corrosion, fouling (macrofouling, microfouling and sedimentation) and other effects that are detrimental to the reliability of the service water system led to the issue of NRC Generic Letter 89-13 “Service Water System Problems Affecting Safety-Related Equipment.” This generic letter continues to be a fundamental guideline for safety related service water systems at all U.S. nuclear plants. The low temperature and pressure service water piping systems are primarily degraded by corrosion. Because of the complexity and random nature of corrosion processes, it is nearly impossible to develop a mathematically deterministic model that accurately predicts pipe wall loss. However, if statistical distributions are used to describe the various corrosion processes, mathematical algorithms that incorporate all of the distributions, iterated a statistically significant number of times, can be used to forecast the most probable number of leaks. This paper predicts the condition of service water piping at Kewaunee Nuclear Power Plant using the described model and includes the expected number of through-wall leaks as a function of operating time.

Within the oil and gas industry there is an emerging trend to estimate expenses for pipelines and system components using a Life Cycle Cost (LCC) basis. This paper describes a new sizing model for swing check valves that can assist in significantly reducing the LCC of the valve. The incremental fuel cost of the compressor arising from pressure loss across the valve is the largest component of the valve’s LCC. The valve’s pressure loss can be minimized by correct valve sizing ensuring full valve opening under normal flow conditions. This new sizing program, applied to an NPS 20 natural gas pipeline, can result in cost savings in the order of two times the capital cost of a swing check valve when compared to traditional sizing methods. The pressure loss across the valve is primarily determined by the opening angle of the valve disc during steady state operation. A steady state valve model was developed and formed the basis for a sizing program for swing check valves. The sizing program assists in optimizing the valve for specified operating conditions. Within margins, the valve opening characteristic can be optimized by adjusting the valve sizing parameters such as valve size, disc weight, counter balance mass and position for a specified set of operating conditions. The LCC of a swing check valve can be further reduced by up to 45% through optimization of the valve design. The sizing program was used in a parametric study to assess the areas relevant in the design optimization of the valve. To further reduce the LCC of swing check valves, research should focus on improving the internal flow profile of the valve, reducing disc weight and eliminating the need for counter balance weights through improving low friction seal design.

The fruit of pepper (Capsicum annuum) commonly wilts (or shrivels) during postharvest storage due to rapid water loss, a condition that greatly reduces its shelf life and market value. The fact that pepper fruit are hollow, and thus have limited water content, only exacerbates this problem in pepper. The collaborators on this project completed research whose findings provided new insight into the genetic, physiological, and biochemical basis for water loss from the fruits of pepper (Capsicum annuum and related Capsicum species). Well-defined genetic populations of pepper were used in this study, the first being a series of backcross F₁ and segregating F₂, F₃, and F₄ populations derived from two original parents selected for having dramatic differences in fruit water loss rate (very high and very low water loss). The secondly population utilized in these studies was a collection of 50 accessions representing world diversity in both species and cultivar types. We found that an unexpectedly large amount of variation was present in both fruit wax and cutin composition in these collections. In addition, our studies revealed significant correlations between the chemical composition of both the fruit cuticular waxes and cutin monomers with fruit water loss rate. Among the most significant were that high alkane content in fruit waxes conferred low fruit water loss rates and low permeability in fruit cuticles. In contrast, high amounts of terpenoids (plus steroidal compounds) were associated with very high fruit water loss and cuticle permeability. These results are consistent with our models that the simple straight chain alkanes pack closely together in the cuticle membrane and obstruct water diffusion, whereas lipids with more complex 3-dimensional structure (such as terpenoids) do not pack so closely, and thus increase the diffusion pathways. The backcross segregating populations were used to map quantitative trait loci (QTLs) associated with water loss (using DART markers, Diversity Arrays Technology LTD). These studies resulted in identification of two linked QTLs on pepper’s chromosome 10. Although the exact genetic or physiological basis for these QTLs function in water loss is unknown, the genotypic contribution in studies of near-isogenic lines selected from these backcross populations reveals a strong association between certain wax compounds, the free fatty acids and iso-alkanes. There was also a lesser association between the water loss QTLs with both fruit firmness and total soluble sugars. Results of these analyses have revealed especially strong genetic linkages between fruit water loss, cuticle composition, and two QTLs on chromosome 10. These findings lead us to further speculate that genes located at or near these QTLs have a strong influence on cuticle lipids that impact water loss rate (and possibly, whether directly or indirectly, other traits like fruit firmness and sugar content). The QTL markers identified in these studies will be valuable in the breeding programs of scientists seeking to select for low water loss, long lasting fruits, of pepper, and likely the fruits of related commodities. Further work with these newly developed genetic resources should ultimately lead to the discovery of the genes controlling these fruit characteristics, allowing for the use of transgenic breeding approaches toward the improvement of fruit postharvest shelf life.

Streszczenie:

The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo conditioning on thermoregulation (heat production and heat dissipation) during 3 phases: (1) conditioning, (2) compensatory growth, (3) heat challenge. d. To investigate how induction of improved thermotolerance impacts on metabolic fuel and the hormones regulating growth and metabolism. Recent decades have seen significant development in the genetic selection of the meat-type fowl (i.e., broiler chickens); leading to rapid growth and increased feed efficiency, providing the poultry industry with heavy chickens in relatively short growth periods. Such development necessitates parallel increases in the size of visceral systems such as the cardiovascular and the respiratory ones. However, inferior development of such major systems has led to a relatively low capability to balance energy expenditure under extreme conditions. Thus, acute exposure of chickens to extreme conditions (i.e., heat spells) has resulted in major economic losses. Birds are homeotherms, and as such, they are able to maintain their body temperature within a narrow range. To sustain thermal tolerance and avoid the deleterious consequences of thermal stresses, a direct response is elicited: the rapid thermal shock response - thermal conditioning. This technique of temperature conditioning takes advantage of the immaturity of the temperature regulation mechanism in young chicks during their first week of life. Development of this mechanism involves sympathetic neural activity, integration of thermal infom1ation in the hypothalamus, and buildup of the body-to-brain temperature difference, so that the potential for thermotolerance can be incorporated into the developing thermoregulation mechanisms. Thermal conditioning is a unique management tool, which most likely involves hypothalamic them1oregulatory threshold changes that enable chickens, within certain limits, to cope with acute exposure to unexpected hot spells. Short-tem1 exposure to heat stress during the first week of life (37.5+1°C; 70-80% rh; for 24 h at 3 days of age) resulted in growth retardation followed immediately by compensatory growth" which resulted in complete compensation for the loss of weight gain, so that the conditioned chickens achieved higher body weight than that of the controls at 42 days of age. The compensatory growth was partially explained by its dramatic positive effect on the proliferation of muscle satellite cells which are necessary for further muscle hypertrophy. By its significant effect of the morphology and functioning of the gastrointestinal tract during and after using thermal conditioning. The significant effect of thermal conditioning on the chicken thermoregulation was found to be associated with a reduction in heat production and evaporative heat loss, and with an increase in sensible heat loss. It was further accompanied by changes in hormones regulating growth and metabolism These physiological responses may result from possible alterations in PO/AH gene expression patterns (14-3-3e), suggesting a more efficient mechanism to cope with heat stress. Understanding the physiological mechanisms behind thermal conditioning step us forward to elucidate the molecular mechanism behind the PO/AH response, and response of other major organs. The thermal conditioning technique is used now in many countries including Israel, South Korea, Australia, France" Ecuador, China and some places in the USA. The improvement in growth perfom1ance (50-190 g/chicken) and thermotolerance as a result of postnatal thermal conditioning, may initiate a dramatic improvement in the economy of broiler's production.

Review question / Objective: The Fragility of Statistically Significant Findings from Depression Randomized Controlled Trials. Condition being studied: Depression is a mental disorder characterized by a range of symptoms, including loss of memory and sleep, decreased energy, feelings of guilt or low mood, disturbed appetite, poor concentration, and an increased risk of suicide. According to a systematic analysis of the Global Burden of Disease Study 2019, depression is recognized as the leading cause of disease burden for mental disorders, accounting for the largest proportion of disability-adjusted life years (DALYs) at 37.3%. The fragility index (FI), which is the minimum number of changes from events to non-events resulting in loss of statistical significance, has been suggested as a means to aid the interpretation of trial results, as the potential inadequacy about robustness of threshold P-value as a tool for reporting binary outcomes in clinical trials. In this systematic review, we want to calculate the FI of randomized controlled trials (RCTs) in depression.
