Effects of the onion residue compost as an organic fertilizer in a vegetable culture in the Lower Valley of the Rio Negro

Purpose Farming production in the lower part of Río Negro Valley (Argentina) has increased considerably during recent years, causing soil degradation and, specifically, decreasing the organic matter contents. This fact requires recovery measures, as organic amendments for soils, to improve its quality. The marked objectives for the present research is to evaluate compost as organic ...

An economic production model for deteriorating items and time dependent demand with rework and multiple production setups

Recently, much emphasis has given to study the control and maintenance of production inventories of the deteriorating items. Rework is one of the main issues in reverse logistic and green supply chain, since it can reduce production cost and the environmental problem. Many researchers have focused on developing rework model, but few of them have developed model for deteriorating ...

Real-time crash prediction on freeways using data mining and emerging techniques

Recent advances in intelligent transportation system allow traffic safety studies to extend from historic data-based analyses to real-time applications. The study presents a new method to predict crash likelihood with traffic data collected by discrete loop detectors as well as the web-crawl weather data. Matched case–control method and support vector machines (SVMs) technique were ...

Differences in Delay, but not Probability Discounting, in Current Smokers, E-cigarette Users, and Never Smokers

Steeper delay discounting in substance abuse populations, compared to non-abusing populations, has been well-established in prior studies. Despite the growing interest in e-cigarettes as a novel and relatively understudied form of nicotine consumption, relatively little is known as to how e-cigarette users discount rewards compared to traditional cigarette smokers and never ...

The self-concept life cycle and brand perceptions: An interdisciplinary perspective

Consumer research has paid scant attention to the full spectrum of a consumer’s self-concept life cycle and its subsequent impact on brand attitude. This article presents a conceptual framework that provides the foundation for future research on how the self-concept, across its full life cycle, impacts brand attitude. The article considers the development of the self-concept from ...

The Politics of Preservation and Loss: Tibetan Medical Knowledge in Exile

This article analyzes the history and development of Tibetan medicine in exile from the perspective of the pervasive Tibetan exile narrative of preservation and loss. Through combined ethnographic and historical data, it shows how the preservation of traditional Tibetan medical knowledge in exile entails a process of a fundamental reinvention of its nature, not only rendering it ...

In-vessel co-composting of yard waste and food waste: an approach for sustainable waste management in Cameron Highlands, Malaysia

Purpose Huge amount of yard waste is produced in cities with excessive agricultural activities like Cameron Highlands, Malaysia where most of the time the yard waste is being managed poorly and big portion of it ends in dump sites. Therefore, this study aims to evaluate the applicability of converting yard waste generated in Cameron Highlands Malaysia into high-quality and fast ...

Cataract Surgery in Patients with a Previous History of KAMRA Inlay Implantation: A Case Series

Introduction The visual outcome of cataract surgery in patients with a previous history of KAMRA inlay implantation is an emerging issue for which limited research exists. The purpose of this study is to describe postoperative visual outcomes in this patient population. Methods This is a case series with retrospective chart review. Seven patients underwent cataract surgery ...

Tribological response of an epoxy matrix filled with graphite and/or carbon nanotubes

Reinforced polymer–matrix composites are widely used under sliding contact conditions in various boating and automotive applications. In this paper, the friction and wear of bulk epoxy and carbon filler reinforced epoxy composites have been investigated using a pin-on-disc tribometer. The effect of different fillers on the tribological behavior of an epoxy has been studied using ...

Does Flexibility Mitigate or Enhance Risk?

In volatile, uncertain, chaotic and ambiguous (VUCA) environment, flexibility is often used as a mechanism to hedge the risk. It would be worthwhile to have a discourse on this complex relationship of flexibility with risk. Risk, in general, is associated with uncertainty and can be measured in terms of probability of failure. In this short discussion of relationship between ...

Current Concepts in Noninvasive Prenatal Screening (NIPS)

Noninvasive prenatal screening (NIPS) represents a significant advance in prenatal screening for trisomy 21 and other conditions. Like any new and rapidly developing technology, it is important for healthcare providers to keep up to date with current and developing issues to help ensure that users of tests such as NIPS are well informed. This review intends to outline and explain ...

GIS-based visualization of integrated highway maintenance and construction planning: a case study of Fort Worth, Texas

Background This paper reports on a case study of the use of visualization of geospatial data that is distributed across data sets and requires integration over time and space to aid decision makers. Like many State Highway Agencies (SHAs) in the United States, the Texas Department of Transportation (TxDOT) is organized along the traditional functional lines of planning, design, ...

A study on leakage current and electrical properties of oleic acid-coated cobalt-doped Mn-Zn ferrite nanocrystalline powders

Background Mn-Zn ferrites have drawn a continuously an increasing interest because of their potential applications as multifunctional devices. These materials simultaneously exhibit ferroelectricity and ferromagnetism. The dielectric and leakage current properties of Cobalt substituted Mn-Zn ferrites coated with oleic acid were not reported. Methods This paper presents the ...

On the decomposition of total impact multipliers in a supply and use framework

This note describes a simple technique of decomposing total impact multipliers derived from input–output analysis. The approach uses a generalised supply and use table framework, explicitly distinguishing between industries and products. Contributions to total impact multipliers can be shown by either industry origin (answering the question: Where is the source of impacts and how ...

Global quantitative biology can illuminate ontological connections between diseases

Owing to its interdisciplinary nature, quantitative biology is playing ever-increasing roles in biological researches. To make quantitative biology even more powerful, it is important to develop a holistic perspective by integrating information from multiple biological levels and by considering related biocomplexity simultaneously. Using complex diseases as an example, I show in ...

Characterization and Leaching of Neodymium Magnet Waste and Solvent Extraction of the Rare-Earth Elements Using TODGA

The rare-earth elements (REEs) are considered as some of the most critical elements in the EU and the USA today. E-scrap, such as end-of-life neodymium magnets, could be a viable secondary source for the recovery of these elements. Neodymium magnets (NdFeB) consist of considerable amounts of Nd, Dy, Pr, and some other REEs, depending on the specific application. Apart from REEs, ...

Mining and Environmental Health Disparities in Native American Communities

Purpose of Review More than a century of hard rock mining has left a legacy of >160,000 abandoned mines in the Western USA that are home to the majority of Native American lands. This article describes how abrogation of treaty rights, ineffective policies, lack of infrastructure, and a lack of research in Native communities converge to create chronic exposure, ill-defined risks, ...

Surface roughness characteristics effects on fluid load capability of tilt pad thrust bearings with water lubrication

The effects of surface roughness characteristics on the fluid load capacity of tilt pad thrust bearings with water lubrication were studied by the average flow model. The flow factors utilized in the average flow model were simulated with various surface roughness parameters including skewness, kurtosis and the roughness directional pattern. The results indicated that the fluid ...
