The Insecticides Effectiveness on Tanymecus Dilaticollis Attack on Maize at NARDI Fundulea
No full textAbstractIn this paper, authors collective present effect of two pesticides applied on maize seeds (Olt variety), Gaucho 600 FS (8.0 l/tonne) and Nuprid 600 FS (8.0 l/tona) and two insecticides applied in vegetation, Calypso 480 SC (90 ml/ha) and Decis Mega (150 ml/ha) against maize leaf weevil attack, at NARDI Fundulea. Also, it performed productivity elements and seeds yields and chemical compozition on Laboratory of Yields Quality of Plant Science Department, Bucharest Faculty of Agriculture. The higher insecticides effectiveness fluctuated between 4.56 when it was applied Nuprid 600 FS and 8.33 when it was applied Calypso 480 SC.The largest attack was recorded to control plots where there is no treatment was applied. The density of plants ranged between 116 and 118 plants/plot, respectively over 65% of saved plants by treatment on seeds with both insecticides. In case of spraying insecticides in vegetation, their effect were insignificant, 31 plants/plot density and 17% saved plants in case of Calypso 480 SC and 16.75 plants/plots density and 9.31% saved plants in case of Decis Mega. The largest yields was of 7,778 kg/ha at insecticides variant with the best effectiveness and density of 65,690 plants/ha. Insecticides showed no influence on chemical composition of seeds at harvesting. But due to high temperatures and drought, the maize seeds accumulated: 12.31% protein; 70.18% starch; 5.05% oil; 1.46% ash; 5.24% fibre
Insights Into Molecular Interaction of Antitumor Drug Mitoxantrone With Anionic Surfactant Sodium Dodecyl Sulfate at Different Temperatures
No full text”The tale of two smart cities”
No full textAnte Scriptum: Every leap of development or revolution in the history of human civilization had as its preamble a period of theoretical searches and confrontations, which were the catalysts of the respective shifts in the historical paradigm. Theorizing has its purpose, and the aim of this paper is to pave the way for an adaptation of architectural theory to new concepts related to the smart city model. We also investigate the predictability of the destiny of the smart city organism and the possible directions of morphogenesis. This article was translated from Romanian by the author. The study is based on revisiting the concepts of place and limit with new connotations developed by technology that has a mediating role vis-a?-vis the individual and communities. By redefining them, the concepts acquire characteristics of variables or mathematical functions, which can effectively study or generate future behavior patterns of smart cities, these dual territorial entities, with body and, here, an artificial intelligence AI (IoT, applications, cloud, software). One of these models is the theory of catastrophe, which can predict the limits of acceptance of phenomenological saturation (in the philosophical sense of Jean-luc Marion) by the individual, or in extremes, by society. We will describe how the theory of catastrophe can be applied using notions of quantum architecture theory, and how the philosophical system of donation described by Marion can help draw the boundaries of the existence of the smart city. The approach is theoretical using inference, observation and exemplification through case studies. The research methods can only be of an eclectic and interdisciplinary nature, linking the theories of architectural atmospheres, of the donation of phenomenological philosophy and of appliedmathematics. The method of translating into quantifiable variables the values of place and limit, is based on the loading of the notion of place of Christian Norberg-Schulz, with valences connected to the specificity given by the mediation of technology between individual and place. The results are models of behavior of a bivalent nature, philosophical and mathematical, to describe a new theory of architecture, a theory of the smart place. This type of architectural place with its set of parameters, is a new element of study, in continuation of research in the field of architecture aimed at reducing risk and preventing losses from hazards that threaten this smart city, either anthropogenic or natural
Effect of SDS Micelles on Actinomycin D – DNA Complexes
No full textDNA thermal denaturation was evaluated as a measure of the effect of antitumor drug actinomycin D on the stability of the double helix and also the effect of SDS micelles on actinomycin D – DNA complexes. The results indicated that the melting temperature of DNA was dependent on drug concentration, increasing with actinomycin D concentration. High thermal stabilization (about 10 °C) of the DNA helix after the association with actinomycin D clearly demonstrates the intercalative binding mode. The presence of SDS micelles leads to the release of intercalated actinomcyin D molecules from DNA double helix and their further relocation in surfactant micelles. These results highlighted that the drug release can be controlled in time and by varying the concentration and nature of surfactant
Mitoxantrone-Surfactant Interactions: A Physicochemical Overview
No full textMitoxantrone is a synthetic anticancer drug used clinically in the treatment of different types of cancer. It was developed as a doxorubicin analogue in a program to find drugs with improved antitumor activity and decreased cardiotoxicity compared with the anthracyclines. As the cell membrane is the first barrier encountered by anticancer drugs before reaching the DNA sites inside the cells and as surfactant micelles are known as simple model systems for biological membranes, the drugs-surfactant interaction has been the subject of great research interest. Further, quantitative understanding of the interactions of drugs with biomimicking structures like surfactant micelles may provide helpful information for the control of physicochemical properties and bioactivities of encapsulated drugs in order to design better delivery systems with possible biomedical applications. The present review describes the physicochemical aspects of the interactions between the anticancer drug mitoxantrone and different surfactants. Mitoxantrone-micelle binding constants, partitions coefficient of the drug between aqueous and micellar phases and the corresponding Gibbs free energy for the above processes, and the probable location of drug molecules in the micelles are discussed
The Holohedrization Effect in Ligand Field Models
No full textThe ligand field theory is an early and yet perennial class of quantum models accounting for the optical and magnetic properties of metal ions as a function of their environment in compounds. In the context of modern quantum chemistry, in order to predict properties from first principles, the ligand field paradigm can serve to illuminate the black box of heavy calculations, extracting heuristic meaning and causal roots. The genuine ligand field models are tacitly affected by an artificial feature, so-called holohedrization. It induces an inversion symmetry, even in cases where the local geometry does not show this element. This aspect received little attention over decades of using the ligand field Hamiltonians. In this work, we systematically investigate, assisted by state-of-the-art ab initio computer experiments, whether holohedrization is a hidden drawback of early models or if it also appears in realistic modeling. We found that the holohedrization trend also appears when using data from modern ab initio calculations
