The bumper sticker signaled a change in the ways that some Americans in the middle decades of the twentieth century chose to think about themselves. For most of our national experience, we Americans have thought about our homeland and relations with other nations in parochial terms. ...
The influence of physical damping on the numerical stability of time integration analysis is an open question since decades ago. In this paper, it is shown that, under specific very general conditions, physical damping can be disregarded when studying the numerical stability. It is also shown that, provided the specific conditions are met, analysis of structural systems involved in extremely hi...
Archaeological excavations carried out at Sudiţi (Buzău County, Romania) some decades ago unearthed severalLinear Pottery culture features which were subsequently interpreted and used by various researchers in an attempt to explain the origin of Chalcolithic cultures (such as Boian). The poorly published findings generatedconflicting or arguable theories. Even if it is not only discovery its ki...
Phase change materials present a unique type of that drastically their electrical and optical properties on the introduction an external or stimulus. Although these have been around for some decades, they only recently implemented on-chip photonic applications. Since reinvigoration few years ago, devices based phase making lot progress, impacting many diverse applications at very fast pace. At ...
In September 2022, the new shipping channel in Poland was opened for service. It connects Port of Elbląg and Gdańsk Bay Poland, cutting through Vistula Spit Lagoon. intended to enable direct access Baltic Sea from without crossing Russian territory. Originally conceptualized decades ago, it has taken its final shape only recently. Its construction associated with several issues, including econo...
The need to examine the heart using a three-dimensional (3D) tool is not new. This complex and dynamic organ has always required 3D real-time understanding. Without this feature, examiner transform two-dimensional images understand its volume, which requires knowledge approximation interactions. Echocardiography was invented three decades ago, improvements resulted in commercial products at beg...
Populations of humpback whales (Megaptera novaeangliae) in the North Atlantic appear to have been increasing at least during last few decades, following cessation substantial hunting almost 100 years ago. Several sources data are available for these populations (survey and mark-recapture estimates absolute relative abundance, estimated catches, proportion animals on two feeding grounds that fro...
Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago. In the first period, diatoms numerically dominated the phytoplankton community in all studied lakes, while in the second period, the same was observed only in three of the ten...
In commemoration of the 20th anniversary of the molecular cloning of the gene for the green fluorescent protein from the jellyfish Aequorea victoria, I would like to reflect on the development of new fluorescence imaging technology in the last two decades. As this technology has become increasingly diversified, it has become more and more of a challenge to come up with a comprehensive and exhau...
