About this deal

The new databases are sorted on star density and not on magnitude. These databases are constructed to have a constant star density per square degrees sky. For navigation (solving) there is no need to fill the database with numerous stars when there are sufficient brighter stars available. But in sky areas where there not many stars the new database goes deeper then the older H18. It goes down to magnitude 21 if required.

The compact and easy-to-use Logic Heat is a heat only boiler, so it works together with a cylinder and a pair of water tanks to keep your home warm and the hot water running. This impressive model is also endorsed by the Energy Saving Trust thanks to its efficient design. Hi, I currently have the older version of ASTAP and i am currently using it in the program Astro Photography Tool ( APT ) We’ll explain this heat only boiler's control panel, as well as taking a look at fault codes and how to operate it most efficiently. You’ll also find top troubleshooting tips and information on how the Logic Heat’s condensate drain works to prevent boiler condensate from freezing. Introducing the Logic Heat Ideal have attached a 2 year parts and labour warranty to the Logic Heat H18 as standard. The heat exchanger has a separate warranty which offers extensive 10 year coverage.

The V17 database will also be replaced in the next days. There will be one new database for the field-of-view range between 10 and 20 degrees and a Johnson-V magnitude version of the D50 for photometry I will call V50. Normally the databases contain the Gaia Bp (blue) magnitude which covers roughly the visual spectrum. For photometry is is better to have the calculated Johnson-V magnitude. HA is the receptor binding protein of the influenza A virus, and is responsible for virus entry into host cells. Before the discovery of the H17 and H18 genes there were 16 subtypes of HA described, H1–H16. Based on their primary sequences, these HA molecules can be categorized into two groups ( Figure 1): group 1 (H1, H2, H5, H6, H8, H9, H11, H12, H13, H16, H17, and H18) and group 2 (H3, H4, H7, H10, H14, and H15) 12, 19, 20, 21, 22. Bat-derived H17 and H18 should be placed into group 1 based on their primary sequences ( Figure 1) 12, 16, 17, 19. A central heating output rating of 18 kW means that the H18 is well suited to properties with up to 15 radiators. The Logic Heat is a modern, efficient condensing boiler, and you can change its output by calling on it to produce more or less heating for your home. The lower the amount of energy your boiler uses, the lower your utility bills will be. In influenza virus there are six further genes, in addition to HA and NA, which encode 12 proteins, with some newly identified protein products 8, 56, 57, 58, 59. These proteins include PA, PB1, PB2, PB1-N40, PB1-F2, PA-X, NP, M1, M2, M42, NS1, and NS2 ( Figure 5). Two additional proteins of N-truncated PAs, PA-N155, and PA-N182, have also been reported [60]. M1 is the third virus-surface envelope protein and NP is responsible for viral RNA binding to form ribonucleoprotein (vRNP), which then combines with PB1, PB2, and PA to form the vRNP complex, a core apparatus responsible for proper virus replication [5]. Previous studies on influenza virus have shown that NP binds to viral RNA destined for transcription by PB1, that harbors a canonical RNA-dependent RNApolymerasedomain, in conjunction with PB2, with cap-binding capacity, that together form the polymerase complex [61]. PB1 also binds directly to the C-terminal domain of PA 62, 63. The N-terminal domain of PA (PAn) functions as an endonuclease to generate small RNA primers that are essential for initiation of viral gene transcription 64, 65. This cleavage of host-derived RNA occurs in a sequence-specific manner 66, 67. Tong and coworkers demonstrated that the combination of NP, PB1, PB2, and PA derived from bat H17N10 is able to transcribe RNA in an influenza A mini-genome reporter assay, and this activity was abrogated when PB1 was removed from the complex [12].

We recommend dusting your boiler with a dry cloth on a regular basis to help keep it clean. For difficult marks or stains you can wipe your boiler down with a damp, non-abrasive cloth, then finish it off using a dry cloth. I currently have the old data base witch is either H17 of H18, I just can't remember which one, I think i went with the largest one. Phylogenetic trees of the hemagglutinin (HA) and neuraminidase (NA) genes of all known influenza A virus subtypes including H17/18 and NA-like N10/11. (A) The categorized HA molecules can be grouped into two groups, group 1 and group 2. The bat-derived H17 and H18 (each marked with a star) belong to group 1, displaying a typical sequence feature of group 1 HA molecules. (B) All the known NAs could also be grouped into two groups: group 1 and group 2. The bat-derived N10 and N11 (each marked with a star) do not belong to either group. They are NA homologs or could be called NA-like molecules. Here we propose that they be categorized as influenza A-like group 3. Heating systems that include a regular boiler take up a fair amount of space around the home so aren’t well suited to properties with little room to spare. As well as the boiler itself, the system will also need a hot water cylinder and cold water storage tank. Keep your Logic Heat boiler working safely and efficiently by having it serviced at least once a year. This job must be carried out by a Gas Safe-registered engineer and will help ensure your central heating system stays in great working condition for years to come.Substitution of the residues in the three secondary elements is important for the HA protein to obtain avian or human SA receptor preference. Different HA subtypes use different substitutions to achieve this goal. For H2 and H3 HAs, Q226L and G228S substitutions in the 220-loop are responsible for the switch between avian and human receptor binding specificities 30, 32 whereas, for H1 HA, different combinations of substitutions at residues 190 and 225 are important for the SA binding preference 33, 34. For H5 HA, a single Q226L substitution is enough to change the receptor binding preference 35, 36. By contrast, for H7 HAs, Q226L substitution is not solely responsible for the acquisition of human receptor binding, and other amino acid substitutions also contribute to the receptor binding switch, especially G186V substitution 37, 38. The Logic Heat H18, manufactured by Ideal, is a condensing regular gas boiler designed for a compact wall-mounted installation. This user guide for the Logic Heat boiler from Ideal Heating will help you get the most out of this reliable central heating solution. With tips taken directly from this boiler’s user manual, this guide will help you make the most of the Logic Heat’s impressive features and benefits. For creating each of these databases my computer has to work a few days. You could argue are the D05 and D20 really required and can't you use the D50 for all applications?. But a small size database could be handy. As an experiment I have also created a D80 but I don't think there are setups imaging consistently with a field-of-view of something like 0.1x0.1 degree.
