A process for the preparation of 2-fluoro-9-(2,3,5-tri-O-benzyl-beta-D-arabinofuranosyl)adenine (I) is described. The process involves reacting a protected 2-fluoro adenine with a protected chlorosugar under controlled conditions of temperature (80-85 DEG C) to produce (I), rather than using a process involving fluorinating a 2-substituted nucleoside precursor of (I).

The invention relates to a lid construction for a composter, which comprises a lid, walls and a bottom 3 which contains insulating material. The lid on the composter has been formed from one or more lid elements 10 which are closely connected to each other and which contain an outer wall 10a, which functions as an impermeable protective layer, and a water-permeable heat insulation 12. There is an ...

The invention relates to a composter which comprises a lid 30, walls and a bottom 31 which contains insulating material. The walls have been formed from one or more elements 20, 40 which comprise a profile 21 which functions as a protective layer and a heat insulating board 50 which has been arranged within this profile such that an air space 48 remains between the front side 43 of the profile on ...

A method for routing a packet of information between two hosts that are coupled to a network. Each of the hosts have a unique network address, and at least one of the hosts is a mobile host (10) that does not have a fixed network coupling location. The method includes a first step of (a) transmitting a packet from the mobile host to a second, destination host on the network through a wireless link...

The object of the invention is a method for dewatering sludge, in which method peat is mixed into the sludge to bring their dry substance content to 20 - 150 %, and after which the mixture is compressed mechanically to separate the water component from it. In accordance with the invention the peat is mixed carefully, in such a way that its structure is not broken. Compression takes place by means ...

A process for the production of recombinant SV-IV protein or its derivatives comprising the following stages is described: - transformation of host cells with a recombinant vector comprising a marker sequence, a promoter for efficient and correct transcription and, under the control of the said promoter, a sequence coding for SV-IV protein or its derivatives, - selecting the said transformed cells...

In a method for continuously dyeing textile yarns (14), the yarns travel continuously in front of a succession of stations (15a, 15b, 15c) for applying dyes of different colors, each station applying a series of spots onto the yarns (14), so that each yarn includes a succession of spots forming a pattern extending over a certain length (L) of the yarn (14) and which is continuously repeated. The s...

Device for varying the geometry of a parasail in flight, useful during landing in fields of confined dimensions and in-flight to avoid excessively sudden ascents as well as to increase the velocity of the sail along its trajectory.

A method of producing 5'-nucleotide, which comprises maintaining a nucleoside suspension in an organic solvent at a temperature not lower than about 20.degree.C, and then subjecting the resultant suspension to a phosphorylatipon of the nucleoside(s). According to the present invention, 5'-nucleotide can be produced from a nucleoside at high purity and high yield in a shortened reaction time, and i...

The rotating cleaning blower to which the invention relates comprises a body 1 provided internally with a small shaft 13 with corresponding bearings 17 to which impeller 2 is fixed, supplemented at its ends by nozzles 3 for the exit of air and consequent cleaning of the area which is to be treated (fig. 3).
