Using a violin teaching apparatus as an example, a training device is disclosed to aid in teaching how to play bowed string instruments. By guiding the motion of a bow teaching apparatus in a manner consistent with the operation of an actual bow, students will learn proper bowing technique. Depending on the immediate pedagogical objective, the motion of a bow teaching apparatus can be limited in terms of back and forth motion as well as the angle relative to the training device. This disclosure can be applied to other bowed string instruments including, but not limited to, a cello and double bass.

The invention discloses a lytic polysaccharide monooxygenase (LPMO) M1 encoding gene coming from magnaporthe grisea, and a preparation method and an application thereof. The lytic polysaccharide monooxygenase LPMO M1 is sourced from the magnaporthegrisea 70-15, which is a pathogenic bacterium of paddy rice. The invention also provides a method of producing the novel LPMO, wherein by means of genetic engineering technical methods, the gene of the novel LPMO is cloned onto an escherichia coli expression vector to obtain an escherichia coli recombination strain that can heterologously express the enzyme. The LPMO M1 prepared through the heterologous expression by the strain can degrade PASC (microcrystalline cellulose processed by phosphoric acid) to generate cello-oligosaccharide and cello-oligosaccharide acid. The LPMO M1 can be widely applied in the fields of chemical engineering, agriculture, feed additives, medicines and the like, and has huge production potential and economic value.

A musical instrument is provided. The instrument is light weight and portable. The instrument includes electrical pickup capabilities but also has the feel of an acoustic instrument. The instrument can be folded to an arrangement that is easy for transport. The folding instrument has maximum similarity to an acoustic cello, including the feel and size when unfolded. The instrument includes a floating soundboard to provide maximum acoustic feel. The instrument further includes an acoustic pickup.

An electric cello is equipped with a pickup unit under a bridge, and strings are stretched to press the bridge; the pickup unit has a bridge tray where the bridge stands and a piezoelectric transducer provided beneath the bridge tray, and the bridge tray is bolted at a side portion under the thick string to the instrument body; however, the other side portion under the thin string is made freely vibrate; while a player is bowing on the strings, the vibrating strings give rise to rolling of the bridge, and the leg portions of bridge are alternately pressed on the side portion and the other side portion; only the vibration of the other side portion give rise to deformation of piezoelectric converter so that the piezoelectric converter is free from interference of the bolted side portion.

A device for restraining or anchoring the endpin of a floor-resting musical instrument such as a cello or a string bass is provided for allowing the musician to hold the musical instrument in a desired position and prevent the endpin from sliding around on the floor surface. The device also protects the surface of the floor from being damaged by a sliding endpin. The device also does not dampen the sound of the musical instrument.

The invention presented herein allows efficient modification of endpins for musical instruments such as cello or bass that use cavities in one or more components that accommodate filler material. The filler materials are composed of materials that affect the acoustic outcomes. The user can modify the endpin acoustic outcomes relatively quickly by changing the filler composition until a desired acoustic outcome is achieved. This allows various acoustic outcomes using the same shape, materials, and construction for the endpin components. Several embodiments are illustrated for endpins, pedestals, stringed instrument sound posts, interior blocks, bass bars, speaker legs and the like.

A stand and cradle suitable for resting a bass or cello instrument upon a floor includes an angled base forming a back support and C-bout support upon which a bass or cello may be rested. The base is further supported by a pivotally coupled angled support which maintains the angle of incline of the base. In one embodiment, a pair of generally planar wood members are used to fabricated the base and angled support. In an alternative embodiment, the base is formed of a pair of tubular legs pivotally joined to together with a pivotally secured angle support also formed of a tubular member. In each embodiment, the cradle and base support is foldable to a collapsed configuration for easy storage and transport.

The invention discloses a human endostatin gene transformed bifidobacterium double-layer microcapsule embedding technology and solves the problem that a transgene bifidobacterium engineering strain is not easy to preserve and is not resistant to gastric acid, wherein the problem hasn't been broken through for a long time. The technology comprises steps of: using milk protein and the like as a first layer for cladding, using Arabic gum, cello-oligosaccharide and the like as a second layer for embedding, and adopting a fluidization spraying method to transform human endostatin gene bifidobacterium to prepare a microcapsual powder. Through successful development of the project provided by the invention, the technology has very ideal effects for preservation, preparation, gastric acid resistance and colonization of the transgene bifidobacterium engineering strain and paves the way for the development of dosage forms of micro-ecological preparations.

The invention discloses a violoncello.
