Cactaceae comprise a diverse and iconic group of flowering plants which are almost exclusively indigenous to the New World. The wide variety of growth forms found amongst the cacti have led to the trafficking of many species throughout the world as ornamentals. Despite the evolution and physiological properties of these plants having been extensively studied, little research has focused on cactus-associated viral communities. While only single-stranded RNA viruses had ever been reported in cacti, here we report the discovery of cactus-infecting single-stranded DNA viruses. These viruses all apparently belong to a single divergent species of the family Geminiviridae and have been tentatively named Opuntia virus 1 (OpV1). A total of 79 apparently complete OpV1 genomes were recovered from 31 different cactus plants (belonging to 20 different cactus species from both the Cactoideae and Opuntioideae clades) and from nine cactus-feeding cochineal insects (Dactylopius sp.) sampled in the USA and Mexico. These 79 OpV1 genomes all share > 78.4% nucleotide identity with one another and < 64.9% identity with previously characterized geminiviruses. Collectively, the OpV1 genomes display evidence of frequent recombination, with some genomes displaying up to five recombinant regions. In one case, recombinant regions span ~40% of the genome. We demonstrate that an infectious clone of an OpV1 genome can replicate in Nicotiana benthamiana and Opuntia microdasys. In addition to expanding the inventory of viruses that are known to infect cacti, the OpV1 group is so distantly related to other known geminiviruses that it likely represents a new geminivirus genus. It remains to be determined whether, like its cactus hosts, its geographical distribution spans the globe.

This is why the Novum Drone could be improved, with relative resistance and very little autonomy. Speaking of the battery, it is this which ensures a greater or lesser autonomy. It has now been two good years that Novum Droneare among the most sold electronic objects in the USA but also throughout the world. They meet this need to be able to take the place of the bird and to be able to discover new places. Using this device it really feels like you are in the air and entering a new world. It is also an object that attracts the curiosity of people who see it flying. You will thus be able to fly over houses, explore places inaccessible on foot, in short have new sensations. So how does it work? Well, you have to know several things. First of all, it's an object that flies through four propellers. This is why the drone is also called a quadcopter which literally means four propellers. Note that some models may have more propellers. To make these propellers work, you need a motor and it needs to be powerful enough to allow the whole drone to fly. This motor is powered by a battery which provides energy to the assembly. Consideration should also be given to the materials used to build the drone. Solid materials must be used so that the machine can withstand wind, rain and shocks. However, the drone must not be too heavy at the risk of not being able to fly. Elevation is actually the same setting as range, because it is cumulative with horizontal distance. So, when you choose a drone, you need to know if you plan to fly it high up or especially horizontally, that is to say over a length. Note that some Novum Droneare dedicated to drone racing, which are more and more popular. More and more professionals are using drones. And this is particularly the case in the audiovisual world. Whether it is for capturing film shots, making reports and more, a drone is very practical. If you try to go too high, you may lose your drone's signal and have some issues. The speed of the drone is expressed in km / h as for a car or any other vehicle. Welcome to Novum Drone this website will allow you to know everything about the drone. There you will find a buying guide, reviews and tests. But also advice on how to use your drone properly. SPACILITY LIGHTWEIGHT, FREE FLYING PACK: At less than 249g, it weighs as much as an apple and fits in the palm of your hand.

In 1955 Edith and Penrose undertook sabbaticals at the Australian National University in Canberra. Edith and her three sons travelled across the USA by train and sailed from California. She and Fritz Machlup corresponded extensively whilst she was away discussing the draft of her book, The Theory of the Growth of the Firm, particularly the final chapters. In Australia she encountered and began to study the multinational firm or enterprise, writing her first articles on the subject. The family returned to the USA via the Suez Canal and sailed from Southampton to New York so that Edith and her sons had completed a round the world voyage.

The phenomenon of «children’s» movements has historical analogs, which traditionally were the result of thoughtful technologies of adults, which were aimed at realizing their interests and achieving specific goals. The use of geopolitical and civilizational approaches has led to the consideration of the phenomenon of «children’s» eco-strikes as a political technology of the initiators of a New World Order. The genesis, essence and purpose of the «Greta Thunberg project» and mass environmental actions in the context of the formation of a New World Order and the interests of Russia have been characterized. It is shown that the initiators of this technology are the «old» globalist and neoliberal elites of Western states, part of the American establishment, international big capital and powerful corporations in the non-material digital sphere. To achieve their goals of neutralizing opponents in the economic and political spheres, they use the protest potential of the «greens», which over the past few decades have actually become part of the Western neoliberal elite. In the context of efforts to create a New World Order, these actors seek to maintain and strengthen their power, continue to exploit third world countries, suppress existing anti-system movements and weaken their main geopolitical competitors – mainly China and Russia, which are looking for safe transport routes and new sources of resources. Therefore, on the initiative of the globalist and neoliberal elites, projects are being put forward to create ecozones in resource-rich «disputed areas» and, as a result, to preserve the prospects for economic activity there. The image of «children’s» eco-strikes, which is presented by the media, reproduces a new social idea and stimulates support from the electorate for the purpose of the transformation of the World Order, which is confirmed by the fact that the movement is massive in various countries of the world. Youth strikes with environmental slogans help to shift the dominant positions from the traditional industrial-resource elite to the digital elite, opening up new financial and economic opportunities and prospects for global leadership for the latter. The intensification of this movement coincided in time with the USA claims to the Northern Sea Route and the development of Arctic resources, which directly affects the interests of Russia.

Abstract Spodoptera eridania is a polyphagous generalist feeder recorded on 200 plants species belonging to 58 botanic families. It is native to the USA and occurs throughout southern USA, Central and South America, and the Caribbean (Pogue, 2002). Due the fact that S. eridania occurs all across the USA and is present in many host plants, several regions around the world are in risk of invasion due to the global trade of vegetables, ornamental and aromatic plants, which can transport larvae and eggs. Even though it is not established in Europe, it has been detected on imported plants from the New World (Karsholt, 1994). The detection of S. eridania in Africa, demonstrates its high dispersal ability, indicating the importance of closely monitoring this species.

The number of classical banks in the world has reduced. In the majority of countries the number of banks does not exceed 200. The uniqueness of the Russian banking sector is that in this respect it takes the third place in the world after the USA and Germany. The paper reviews the conclusions of the economic theory about the optimum structure of the banking market. The empirical analysis shows that the number of banks in a country is influenced by the size of its territory, population number and GDP per capita. Our econometric estimate is that the equilibrium number of banks in Russia should be in a range of 180-220 units.

The authors point out that the local market crisis - on the USA substandard loan market - has led to the uncertainty of the world financial market. It has caused the growing demand for liquidity in the framework of the world financial system. The Russian banking sector seems to be more stable under negative changes than banking systems of other emerging markets. At the same time one can assume that the crisis will become the factor of qualitative shift in the character of the Russian banking sector development - the shift from impetuous to more balanced growth.

Authors from the Christian Right in the USA situate the September 11 attack on New York and Washington within God's intentions to bring America into the divine schedule for the end of the world. This is true of Pat Robertson and Jerry Falwell, and other leading figures in the ‘Christian Coalition’. This article analyses how Christian fundamentalists assess the roles of the USA, the State of Israel, Islam, Iraq, the European Union and Russia within what they perceive to be the divine plan for the future of the world, especially against the background of ‘9/11’. It argues that the ideas of the Christian Right and of President George W. Bush coalesce to a high degree. Whereas before 9/11 many American mega-church preachers had aspirations to direct political life, after the events of that day the President assumes some of the roles of a mega-religious leader.
