Costus afer (C. afer) is a plant commonly known as ginger lily, spiral ginger, or bush cane. It is reportedly used in traditional medicine practice (TMP) to treat and manage many ailments including diabetes mellitus, stomach ache, arthritis, inflammation, and gout. These purported ethnomedicinal uses have triggered many research studies on the plant to amass scientific evidence.

The subject of corporate bankruptcy has been of interest to financial academicians and practitioners alike. Researchers have directed most of their attention to accounting-based models for predicting bankruptcy filings. Although some research has attempted to estimate the probability and costs of bankruptcy, a very limited amount is centered around the outcome of bankruptcy proceedings. Specifically, little is known about the circumstances that determine whether the firm will liquidate, successfully reorganize, or become an acquisition of another firm after filing for court protection.

The decision to vertically integrate services and deliver care has both management and policy concerns for healthcare in the United States. The change in reimbursement, which was enacted with the Balanced Budget Act of 1997, influenced the availability of post acute services for acute hospital inpatients. Prior to this change, post acute services were reimbursed based on cost similar to the pre DRG era of Medicare reimbursement. The change in payment had the potential to make discharging patients more difficult resulting in a prolonged length of stay without additional payment and at increased

Abstract:
Due to its subjective nature, the concept of value is not one that is easily defined. Marketers often refer to a product's 'value proposition' as an explanation to why an operator should buy a product or use a service. This statement should convince a potential operator that one particular product or service will add more value or better solve a problem than other similar offerings. In the rotorcraft market, this value proposition is often tied to capabilities of the helicopter and is typically defined as a composite metric. This metric is then compared to the acquisition cost to get a sense o

Abstract Costly monthly maintenance of lead lined steel sulfuric acid concentrators lead to the installation of PVDF (polyvinylidene fluoride) lined fiberglass replacements that have been maintenance free after 10 years of service. Spent sulfuric acid is concentrated from 45% to roughly 60% at nearly full vacuum and over 200 °F (93 °C) for recycle back to the process.

Abstract:
Abstract This paper is dedicated to material selection and Life Cycle Cost (LCC) of storage tanks. There are many materials options for the construction of storage tanks among which are coated carbon steels, austenitic stainless steels and duplex stainless steels. Material choice requires the designer to consider several features: material performance, material cost and availability, weight and strength aspects, fabrication and maintenance costs. All are important factors in determining the lowest project and life cycle cost. Duplex stainless steels are more often considered for storage tanks

Abstract:
Abstract As older pipeline coatings deteriorate and disbond, companies quickly realize the high cost of maintaining these lines. Cathodic protection requirements increase, and corrosion and stress corrosion cracking (SCC) can occur on the pipeline surface. In an effort to reduce the costs associated with maintaining these aging pipelines, an economical means of maintaining the integrity of these lines has been investigated. After four years of large-scale pipeline recoating, it has been demonstrated that pipeline recoating programs can be an attractive alternative to replacing corroded pipe.

Full text
Abstract:
Free Trade Agreements (FTA) attract significant interest, but after these treaties are signed not all exporters use them. We provide a model of heterogeneous utilization, also developing a novel method to estimate treaty-utilization costs. We later apply the model to estimate the evolution utilization costs for the FTA between the US and a small open economy, Chile. Consistent with other studies, we find that utilization is indeed partial (on average 67% on the first year of the treaty, with 10 percentage points more at the third year). This made tariff revenues to the US 10% higher than expec

Abstract:
In this best practice paper a mixed integer optimization approach to the selection of sanitary landfill site sizes and locations in a regional context is explained and illustrated using stylized cost and location information adapted from a real case study. After reviewing the basics of the heuristic approach to solid waste disposal site selection, the optimization model is laid out and solved in the case study context, initially in terms of financial costs. In a subsequent section, a way of incorporating the relative environmental damages of alternative locations into the model is suggested, a

We use a large-scale randomized experiment to study the impact of augmenting staffing in the world’s largest public early childhood program: India’s Integrated Child Development Services (ICDS). Adding a half-time worker doubled net preschool instructional time and led to 0.29σ and 0.46σ increases in math and language test scores after 18 months for children who remained enrolled in the program. Rates of stunting and severe malnutrition were also lower in the treatment group.

Abstract:
Vehicle electrification is a major component of many sustainability goals and frameworks. Research suggests that battery costs account for a large portion of the price premium for electric vehicles (EVs) relative to internal combustion engine vehicles (ICEVs) and that price parity, which will likely not occur until after 2030, will rely on decreasing battery costs.

This presentation comments on Douglas H. Brooks' paper Asia's infrastructure, trade costs and regional co-operation which discusses topics of trade dynamics within developing Asia. After highlighting Brooks' key points, it covers issues on trade costs, namely, avoidable versus unavoidable "Non-Tariff" trade costs and the reduction of "Non-Tariff" trade costs as a policy objective. Then it presents the implications of a world where each economy achieves "optimal" reductions in "non-tariff" trade costs.

Abstract:
Air pollution has become a major public issue and it is now evident that unburned hydrocarbons, CO, and NOx must meet increasingly restrictive standards. The emissions of nitrogen oxides by gas turbines are of concern because of their high toxicity and their role in the formation of photochemical smog. The formation of NOx occurs in a gas-fired gas turbine when combustion temperatures exceed a critical level for sufficient time to allow atmospheric nitrogen and oxygen to combine. For those gas turbine applications where steam or ultra-pure water are readily available, then steam or water injec

Abstract:
This paper investigates the economics of deploying carbon capture and storage (CCS) on gas-fired power plants while covering its entire value chain, i.e., carbon capture, transport, and storage, and conducting a thorough sensitivity scenario analysis. Our analysis shows that adopting CCS translates into a carbon dioxide (CO2) capture cost ranging from $86 to $130 per tonne ($/tonne) for newly built and retrofit plants, depending on the natural gas price. The latter was found to be a significant parameter impacting costs. Transport and storage will result in an additional ~$24/tonne to the over

SARS-CoV-2 screen testing is routine serial testing of asymptomatic individuals outside of outbreak or known exposure settings to identify staff infectious with SARS-CoV-2 and exclude them from work. Routine asymptomatic screen testing of staff has been proposed as a potential mitigating strategy to reduce SARS-CoV-2 introduction and transmission in long-term care (LTC) homes. A rapid review of the literature found no real-world evidence to either support or refute screen testing in preventing LTC home COVID-19 outbreaks. There are several direct harms associated with screen testing, as well a

Abstract:
Women who seek emergency treatment for abortion complications—bleeding, infection, and injuries to the reproductive tract system—should be a priority group for reproductive health care programs. These women often receive poor-quality services that do not address their multiple health needs. They may be discharged without counseling on postoperative recuperation, family planning (FP), or other reproductive health (RH) issues. Women who have had an induced abortion due to an unwanted pregnancy are likely to have a repeat abortion unless they receive appropriate FP counseling and services. Preven
