Considering the strategic importance of coastal areas from various aspects, their protection against waves is a coast management necessity. Since long ago, strong coastal structures have protected coasts, but since they disturb the coastal ecosystem balance, effort has been made to use them less or make them more compatible with the coast. This research is specifically aimed to estimate the eff...

Many methods have been reported on improving the photogenerated cathodic protection of nano-TiO2 coatings for metals. In this work, nano-TiO2 coatings doped with cerium nitrate have been developed by sol-gel method for corrosion protection of 316 L stainless steel. Surface morphology, structure, and properties of the prepared coatings were investigated by X-ray diffraction, X-ray photoelectron ...

In many socio-economic surveys, the variable of interest is sensitive or stigmatizing. Examples include tax evasion, criminal conviction, alcohol expenses, induced abortion, drug abuse, etc. In such situations, the technique of randomized response is very useful as it does not require the respondent to reveal his/her true value. The issue of privacy protection is important in this context and a...

Introduction Power systems have undergone a great deal of change in the past decade. The United States electric power grid was deregulated in the late 1990’s. As a result, it is increasingly operated with smaller generation reserves and more transmission congestion. If deregulation continues, it seems likely that power flows will be larger and will fluctuate to a greater extent in future years....

According to demographic trends, the ratio of senior citizens in the overall population of the Republic of Serbia is rising. This generates the need to create socially acceptable and economically sustainable models for the protection of the elderly. The goal of this paper is to stress the necessity of analyzing and evaluating the efficiency of social protection services aimed at senior citizens...

The fundamental performance criterion for Dynamic Spectrum Access (DSA) approaches is the protection of the Primary U ser (PU). However, for DSA to become a reality, it is crucial to also ensure some Quality of Service (QoS) support for the Secondary U ser (SU) communication. In this paper, we propose sensing based opportunistic spectrum access approaches achieving both, protection of the PU, a...

Eco-efficiency is an important sustainable development and circular economy construct that conceptualizes the relationship between industrial output, resource utilization, and environmental impacts. This paper conducts an eco-efficiency analysis for basin industrial systems using the decomposition model approach. Using data on 10 cities in China’s Songhua River basin, we illustrate the evolutio...

BACKGROUND Respiratory protection efficiency of facemasks is critically important in the battle against communicable respiratory infections such as influenza and severe acute respiratory syndrome (SARS). We studied the spatial distributions of simulated virus-laden respiratory droplets when human subjects wore facemasks and were exposed to regulatory viral droplets by conducting in vivo experim...

Newcastle disease (ND) leading to heavy economic losses to the poultry industry worldwide is caused by Newcastle disease virus (NDV). Even though intensive vaccination programs have been implemented in many countries, virulent NDV can still be frequently isolated in well-vaccinated flocks. We compared the protection efficiency of LaSota and two sub-genotype VIId vaccines, NDV/AI4 and NDV O/AI4,...

Recently, consistency in government policies between economic efficiency and environmental protection becomes increasingly important for electric power companies. In particular, the problem of consistency influences a decision-making process in management for a utilization of power plants and a fuel mix. This study is interested in the performance assessment of power plants under U.S. environme...
