Zhang, Huazhong Agricultural University research team led by Academician inspired over 10 years of study, first discovered and cloned a simultaneous control of rice plant height, heading date and kernel number per gene, named Ghd7. 5 at the date of the team research papers in internationally renowned scientific journal "Nature - Genetics," published.

    Researchers to identify a single gene can determine Ghd7 rice plant height, heading date and the three characteristics of grains per panicle. Previous studies have identified characteristics may determine more than rice chromosome 7 region, but not accurate to any particular gene.

    According to Academician Zhang inspiration, the past that need to change many genes can increase rice yield, now we just need to control a single gene can increase production. Rice research team is also on chromosome 7 near the centromere, using map-based cloning of this gene was isolated.

    Of verification, the current most high-yield rice varieties contain Ghd7 gene. Wild-type Ghd7 gene can significantly delayed heading date, plant height and grains per panicle increased significantly. Summer conditions in Wuhan, with wild-type Ghd7 gene NILs compared with the recurrent parent Zhenshan 97 23 days late heading, plant height increased by 30 cm, grain number doubled, and the sturdy stem lodging, single line output can be increased by 50%. Wild-type Ghd7 gene transfer through biotechnology to some spike, early heading varieties, these varieties can multiply the number of grains per panicle, accompanied by increased plant height, heading date delay.

    The results also showed that the gene and geographical adaptability of rice varieties are closely related. In low latitude regions, wild-type Ghd7 rice gene can make full use of light and temperature conditions, large panicle yield.

    Academician Zhang inspiration that has always been high and stable yield crops, the ultimate goal of scientific research affecting the rice yield per unit area of factors including the number of spikelets per panicle, panicles, grain weight and seed setting rate, determines the growth period of rice varieties seasonal and regional adaptability of the main factors affecting the stable. Rice Ghd7 cloned gene, greatly increase the number of traits of complex genetic and molecular basis of understanding. In academic research, but also on traditional genetics of the rare pleiotropic effects is a good example.

    Ghd7 successfully separated genes, indicating the production of such a complex, such as the number of characters, but also with the quality traits, like improved through biotechnology. Information about the gene, can be used directly from the genetic resources of rice varieties to increase production and to explore ecological adaptation of the significance of good genes, genetic improvement of crop varieties. As the point of clear, Ghd7 successfully isolated genes can greatly shorten the screening time of high-yielding rice varieties, from the past 10 years, reduced to 5 years.

Home theater in a box

A "home theater in a box" (HTIB) is an integrated home theater package which "bundles" together a combination DVD player/ multi-channel amplifier (which includes a surround sound decoder, a radio tuner, and other features), speaker wires, connection cables, a remote control, a set of five or more surround sound speakers (or more rarely, just left and right speakers) and a low-frequency subwoofer. outdoor survival kit

They are manufactured by most makers of consumer electronics. At the lowest end of the price range are "2.1" units which include a combination DVD player/three channel amplifier with only the most basic features, a remote control, left and right speakers, and a small subwoofer speaker (under $100 US). Models in the middle price range include HTIBs made by RCA, Electrohome, Philips, Samsung, Panasonic and Sony (from $300 to $800 US). At the high end of the price range, Bose Lifestyle HTIB systems can cost over $3000 US. drill press vice

Market positioning

HTIBs are marketed as an "all-in-one" way for consumers to enjoy the surround sound experience of home cinema, even if they do not want tor do not have the electronics "know-how"--to pick out all of the components and connecting cables individually. If a consumer were to buy all of the items individually, they would have to have a basic knowledge of electronics, so they could, for example, ensure that the speakers were of compatible impedance and power-handling for the amplifier. As well, the consumer would have to ensure that they purchased all of the different connection cables, which could include S-Video cables, optical connectors, speaker wire, and RCA connectors.

On the downside, most HTIBs lack the features and "tweakability" of home theater components which are sold separately. For example, while a standalone home theater amplifier may offer extensive equalization options, a HTIB amplifier may simply provide a few factory-set EQ presets. As well, while a standalone home theatre subwoofer may contain a range of sound-shaping circuitry, such as a crossover control, a phase inversion switch, and a parametric equalizer, a HTIB subwoofer system usually has its crossover point set at the factory, which means that the user cannot change it. In some cases, the factory preset crossover point on an HTIB subwoofer may cause it to sound too "boomy" in a room.

Features

A typical HTIB generally consists of a central receiver unit which usually contains a DVD player (some systems separate the DVD player into a separate unit) and a radio tuner and a series of speakers for surround sound use, generally including a subwoofer. The least expensive systems usually have a passive subwoofer, which is amplified by the HTIB systems typically do not include a television set or monitor with which to display the visual material.

There are systems in this class that are sold without a DVD player and are designed to integrate with existing video setups where there is already one, such as a DVD recorder or a DVD/VCR combo unit. The speaker cabinets supplied with most systems in this class are generally fairly small compared to typical stereo speakers, and are meant for wall- or shelf-mounting in tight spaces. There are some systems in this class that are supplied with slim freestanding speakers that stand on the floor. This may be typical of higher-priced systems that are equipped with more powerful amplifiers or most of the "receiver-only" packages that do not come with a DVD player.

Some HTIBs use proprietary connectors between components, sometimes even combining several different wires into one connector, to reduce cable clutter and increase the ease of installation. However, this can impede interoperability between different audio/visual devices and makes upgrading certain parts impossible. This may also be used by manufacturers to limit what a consumer can do with a low-end model and encourage them to upgrade should they want more autonomy.

A few manufacturers, notably Sony, have implemented wireless connection technology for the surround speakers in this class of equipment. This technology may be available as standard with some of the high-priced models or may be supplied as an aftermarket kit that only works with selected models in the manufacturer's range. It usually manifests in a line-level feed over a proprietary wireless link to a separate power amplifier used for the surround-sound channels. This link-receiver and power amplifier can be built in to one of the surround speakers or housed in a black box that the surround speakers are connected to. Some higher-end HTIB models offer additional features such as 1080i video resolution upscaling, a 5-disc platter, HDMI inputs, USB connectivity, Bluetooth support, Wifi support, iPod dock and a hard disk.
