Cellular damage to phytophthora infestans in tomato leaves treated with oxadi...dinomasch
The document describes an ultrastructural study of cells of Phytophthora infestans, the pathogen that causes late blight in tomatoes and potatoes, after treatment with the fungicide oxadixyl. The study found that in some hyphae and haustoria of P. infestans in infected tomato leaves treated with oxadixyl, there was massive accumulation of electron-dense deposits near the plasma membrane and mitochondria. This led to mitochondrial degeneration and likely cell death. However, no changes were observed in the endoplasmic reticulum or number of ribosomes. Some hyphal cell walls were also thickened after oxadixyl treatment. The damage to fungal cells from oxadix
Assessing the Risk of Resistance in Pseudoperonospora cubensis to the Fungici...dinomasch
The study assessed the risk of resistance developing in the oomycete fungus Pseudoperonospora cubensis, which causes cucumber downy mildew, to the fungicide flumorph. Researchers compared flumorph to dimethomorph and azoxystrobin in terms of the ease of isolating resistant mutants, the level of resistance induced, and the fitness of resistant mutants. Attempts to induce resistance to flumorph and dimethomorph by adapting sporangia on treated leaves were unsuccessful. Moderately resistant mutants were isolated using UV mutagenesis for flumorph and dimethomorph, but resistance levels were much lower than for azoxystrobin-resistant mutants.
The document provides an alphabetical listing of subject labels and terms related to science and technology. It includes over 50 subject labels that could be used to categorize terms in a dictionary of science and technology, covering topics like acoustics, astronomy, biology, chemistry, computing, dentistry, engineering, genetics, and more. It also provides examples of defined terms ranging from A1 symbol to absolute zero and indicates the subject area or areas each term relates to.
The document provides information about the letter S, including its history, pronunciation, uses, and various forms. It traces the development of the letter S from ancient Egyptian and Semitic symbols through Phoenician, Greek, Roman, and modern scripts. The letter S has two common pronunciations in English, either a hissing sound or sounding like z. It is frequently used in abbreviations and has various representations in writing systems, flag codes, and Braille. Examples are given of printed, cursive, roman, italic, and computer letterforms.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.
This document discusses Samba and IPv6 support in Windows Vista. It notes that while raw SMB file sharing works over IPv6 in Samba 3 and Samba 4 with some workarounds, Samba cannot currently function as an Active Directory domain controller for IPv6 clients like Vista. It recommends that further work is needed in Samba 4 to fully support IPv6, especially for Active Directory functions, to allow organizations migrating to Vista and IPv6 networks to use Samba.
The increasing role of direct reduced iron (DRI) in global steelmakingdinomasch
Direct reduced iron (DRI) is increasingly being used as a source of low-residual iron in electric arc furnace steelmaking. As steelmaking efficiency has improved through techniques like continuous casting, the availability of high-quality ferrous scrap has decreased. At the same time, electric arc furnace steelmaking has grown in popularity relative to traditional blast furnaces. This has increased demand for scrap and led to price volatility. DRI provides a more reliable and competitive alternative to scrap, avoiding issues like residual contaminants. Major DRI production technologies are Midrex and Hyl, which reduce iron ore to metallic iron below the melting point of iron using reducing gases. Global DRI capacity has expanded significantly in recent decades to meet the growing demand.
AspectC++: Language Proposal and Prototype Implementationdinomasch
This paper proposes language extensions called AspectC++ to support aspect-oriented programming in C/C++. It presents the key concepts of AspectC++, which are similar to AspectJ but adapted for C/C++. These include pointcut expressions to match join points, advice declarations to specify code execution at join points, and aspect declarations to modularly implement crosscutting concerns. The paper also discusses the rationale for AspectC++'s design and its grammar integration into C/C++. It illustrates the concepts using an example and outlines the prototype compiler implementation.
Improved kernel based port-knocking in linuxdinomasch
This thesis presents TCP Stealth, a new port knocking technique designed to improve security and usability over previous port knocking designs. TCP Stealth replaces the random TCP sequence number with an authentication token that verifies the client and optionally integrity protects the first bytes of the TCP payload. The thesis describes an implementation of TCP Stealth called Knock for the Linux kernel and a library called libknockify that allows enabling Knock without recompiling applications. Experimental results show TCP Stealth is compatible with most existing Internet infrastructure.
Froth flotation is a process for separating minerals based on their ability to adhere to air bubbles in water. Hydrophobic mineral particles attach to bubbles and are carried to the surface, while hydrophilic particles remain in the water. The process involves many interrelated factors including reagents, equipment design, and operational parameters. Collectors are chemicals that render mineral surfaces hydrophobic, allowing bubbles to attach. Proper particle-bubble contact and stable froth layers are also required for effective mineral separation by froth flotation.
This document summarizes heterojunction silicon-based solar cells. It discusses the motivation for developing heterojunction solar cells using thin amorphous silicon layers on crystalline silicon to improve efficiency. Achievements include laboratory cells reaching over 23% efficiency and commercialization by Sanyo of their HIT solar cells. Challenges include reducing optical, recombination, and resistance losses through techniques like surface texturing, high quality thin film deposition, and contact design.
