Fire-Resistant Plants for Oregon Home Landscapes
FFire-ire-RResistantesistant PlantsPlants forfor OregonOregon HomeHome LandscapesLandscapes Suggesting specific types of vegetation that may reduce your risk from wildfire. Stephen Fitzgerald Area Extension Forester and Associate Professor Amy Jo Waldo Area Extension Horticulture Agent and Assistant Professor OSU Extension Service 1421 S. Hwy 97, Redmond, OR 97756 Introduction Oregon has many wildfire prone areas. In these places, fires are a natural part of the changing landscape. As homes are built in these areas, special precautions must be taken by the homeowner to pro- tect their property. Installation of fire- resistive roofing is critical to preventing firebrands from igniting the home from a roof fire. Well maintained fire-resistant vegetation and irrigated landscape is also critical within close proximity of a home. These actions DO NOT insure that your home will survive a wildfire, but they provide for a good chance of structural survival. Implementation of FireFree [www.firefree.org] and FireWise [www.firewise.org] activities can also significantly improve chances of a home surviving a wildfire. Fire-resistant vegetation. When landscaping around a home, most homeowners are interested in creating a landscape that is aesthetically pleasing, compliments their home, and has varia- tions in color, texture, flowers, and foliage. If your home is located in or adjacent to forests or rangeland, you should also consider the flammability of plants within your home landscape. Flammable plant material in your land- scape can increase the fire-risk around your home. The 1991 Oakland Hills Fire in California is a prime example of how flam- mable plant material (Eucalyptus trees) can act as fuel and contribute to the inten- sity of a wildfire. -

Hypericum also displays an ample variety of other biological actions, such as hypotensive, analgesic, anti-infective, anti-oxidant, and spasmolytic abilities. However, recent investigations highlighted that this species could be advantageous for the cure of other pathological situations, such as trigeminal neuralgia, as well as in the treatment of cancer. This review focuses on the in vitro and in vivo antitumor effects of St. John’s Wort (Hypericum perforatum), its derivatives, and other Hypericum species in hematologic malignancies. -

We examined the possible antigenotoxic/genotoxic properties of methanolic extract of H. olympicum subsp. olympicum (HOE) on human lymphocytes by employing sister chromatid exchange, micronucleus and comet assay and analyzed its chemical composition by GCxGC-TOF/MS. The anti-growth activity against MCF-7 and MDA-MB-231 cell lines was assessed by using the ATP viability assay. Cell death mode was investigated with fluorescence staining and ELISA assays. The major components of the flower and trunk were determined as eicosane, heptacosane, 2-propen-1-ol, hexahydrofarnesyl acetone and α-muurolene. HOE caused significant DNA damage at selected doses (250–750 µg/ml) while chromosomal damage was observed at higher concentrations (500 and 750 µg/ml). HOE demonstrated anti-growth activity in a dose-dependent manner between 3.13–100 µg/ml. -

(http://www.sciencedirect.com/science/article/B6T6R-4W6XYK9- 1/2/708e866c3d7f370d81917ed145af525a) Abstract: Introduction The antioxidant properties of essential oils (EOs) have been on the centre of intensive research for their potential use as preservatives or nutraceuticals by the food industry. The enormous amount of information already generated on this subject provides a rich field for data-miners as it is conceivable, with suitable computational techniques, to predict the antioxidant capacity of any essential oil just by knowing its particular chemical composition. To accomplish this task we here report on the design, training and validation of an Artificial Neural Network (ANN) able to predict the antioxidant activity of EOs of known chemical composition.Methods A multilayer ANN with 30 input neurons, 42 in hidden layers (20 --> 15 --> 7) and one neuron in the output layer was developed and run using Fast Artificial Neural Network software. The chemical composition of 32 EOs and their antioxidant activity in the DPPH and linoleic acid models were extracted from the scientific literature and used as input values. From the initial set of around 80 compounds present in these EOs, only 30 compounds with relevant antioxidant capacity were selected to avoid excessive complexity of the neural network and minimise the associated structural problems.Results and discussion The ANN could predict the antioxidant capacities of essential oils of known chemical composition in both the DPPH and linoleic acid assays with an average error of only 3.16% and 1.46%, respectively. -
Lamiaceae), a Doubtful Species from Korea

E-mail: [email protected] Abstract The species Microtoena coreana has long been extremely doubtful. This species is endemic to South Korea, and only the holotype has been collected. The author, who described this species as new, placed it into the genus Microtoena without confidence. Some taxonomists even considered that it might belong to another genus instead of Microtoena. However, no conclusion has been achieved. In the present study, the holotype of Microtoena coreana was found and carefully examined. This holotype possesses 5-lobed corolla, broadly campanulate calyxes, and long-exserted stamens, which make it distinct from all the other species of Microtoena. The results of examination on a large number of specimens and statistical analysis of multiple characters clearly show that the holotype of Microtoena coreana is an element of Tripora divaricata (= Caryop- teris divaricata). Therefore, the name Microtoena coreana is here excluded from the genus Microtoena, and is reduce to a synonym of Tripora divaricata. In addition, the lectotype of Tripora divaricata is designated in the present article. Keyword: Caryopteris, lectotypification, principal coordinate analysis, taxonomy, Tripora Introduction The genus Microtoena Prain (1889: pl. 1872) of Lamiaceae is distributed in southwestern China and adjacent regions. -
Caryopteris: Your True Blue Garden Friend
Caryopteris: Your True Blue Garden Friend By Elaine Homstad, Fairfax Master Gardener It is often said that plants with flowers in blue shades can be rare and hard to find. Blue can be a wonderful addition to almost any garden palette. But this plant is special to me because of its ability to attract pollinators. The hub of activity as nature puts on a show tops anything on television. It does require you to wait until late summer for its blooms, but they are definitely worth it. What is this plant? It is Caryopteris, also known as Bluebeard or Blue Mist. Caryopteris x clandonensis is a genus of woody flowering shrubs in the family Lamiaceae, the mints, which include many aromatic herbs and plants. However, you may also find it classified in the Verbenaceae family at some sources. Extension University State Mississippi Caryopteris is native to China and eastern Asian countries, photo: and its hybrids enjoy growing in USDA zones 5 to 9. It is a small woody perennial shrub with grey/green leaves that grows to a 2- to 4-foot spread. It prefers less rich soil, with a middle pH range of 6 to 8, as long as it is well-drained. Once established, it can handle drought conditions. It does prefer full sun, six or more hours per day, but will also bloom in partial shade conditions, though not so profusely. Its blooms are in clusters known as cymes that spread out along the upper part of the slender, graceful stems of the plant. The buds in the cymes open to small feathery puffs, leading to the common name of Blue Mist or Blue Spirea. -
Dwarfing of Caryopteris × Clandonensis 'Grand Blue': The
Acta Universitatis Sapientiae Agriculture and Environment, 4, (2012) 19–30 Dwarfing of Caryopteris × clandonensis ‘Grand Blue’: the interaction between growth retardants and the transpiration rate, stomatal conductance, and CO2 fixation Julianna HARMATH email: harmath [email protected] Corvinus University of Budapest, Department of Floriculture and Dendrology, Faculty of Horticultural Science, Budapest, Hungary Abstract. The effect of growth retardants Alar, Bumper, Cultar, Cyco- cel, and Mirage was studied on Caryopteris × clandonensis ‘Grand Blue’ young plants in an experiment during May-October, 2011. The young plants were sprayed with the chemicals three times during the summer. The most effective growth retardant was Cultar. The influences of these retardants on stomatal conductance, transpiration rate, and CO2 fixation on leaves were also measured. The differences between the treatments on the 1st day after the last spraying were the most marked and statistically significant, the differences on the 24th day were still notable but not sig- nificant, while on the 43rd day after the last spraying, they decreased to minimum. As a final conclusion, it can be stated that the effect of the different growth retardants faded away after three weeks. Keywords: plant growth regulators, photosynthetic rate, Caryopteris × clandonensis ’Grand Blue’ Introduction Caryopteris × clandonensis is a summer-flowering semi-shrub reaching a height of 1-1.5 m; it is praised for its late blooming time. The flowering but 20 J. Harmath smaller plant would have a higher market value because the small, compact plants, full of flower are preferred on the market, especially in the autumn sea- son. The aim of the experiment was to decrease the size and the growing time of the plant, and after the dwarfing researches, to measure the photosynthetic activity of the plant. -

Quantum Attacks without Superposition Queries: the Offline Simon’s Algorithm Xavier Bonnetain1,3, Akinori Hosoyamada2,4, Mar´ıaNaya-Plasencia1, Yu Sasaki2, and Andr´eSchrottenloher1 1 Inria, France {xavier.bonnetain,maria.naya plasencia,andre.schrottenloher}@inria.fr 2 NTT Secure Platform Laboratories, Tokyo, Japan {hosoyamada.akinori,sasaki.yu}@lab.ntt.co.jp 3 Sorbonne Universit´e, Coll`ege Doctoral, F-75005 Paris, France 4 Nagoya University, Nagoya, Japan Abstract. In symmetric cryptanalysis, the model of superposition queries has led to surprising results, with many constructions being broken in polynomial time thanks to Simon’s period-finding algorithm. But the practical implications of these attacks remain blurry. In contrast, the re- sults obtained so far for a quantum adversary making classical queries only are less impressive. In this paper, we introduce a new quantum algorithm which uses Simon’s subroutines in a novel way. We manage to leverage the algebraic struc- ture of cryptosystems in the context of a quantum attacker limited to classical queries and offline quantum computations. We obtain improved quantum-time/classical-data tradeoffs with respect to the current liter- ature, while using only as much hardware requirements (quantum and classical) as a standard exhaustive search with Grover’s algorithm. In particular, we are able to break the Even-Mansour construction in quan- tum time O˜(2n/3), with O(2n/3) classical queries and O(n2) qubits only. In addition, we improve some previous superposition attacks by reducing the data complexity from exponential to polynomial, with the same time complexity. Our approach can be seen in two complementary ways: reusing superpo- sition queries during the iteration of a search using Grover’s algorithm, or alternatively, removing the memory requirement in some quantum attacks based on a collision search, thanks to their algebraic structure. -
