structure Synthesis, crystal structure and Hirshfeld surface analysis of N-(4-methoxyphenyl)picolinamide By journals.iucr.org Published On :: 2024-11-14 The synthesis, crystal structure, and Hirshfeld surface analysis of N-(4-methoxyphenyl)picolinamide (MPPA), C13H12N2O2, are presented. MPPA crystallizes in the monoclinic space group P21/n, with a single molecule in the asymmetric unit. Structural analysis reveals that all non-hydrogen atoms are nearly coplanar, and the molecule exhibits two intramolecular hydrogen bonds that stabilize its conformation. Supramolecular features include significant intermolecular interactions, primarily C—H...π and various hydrogen bonds, contributing to the overall crystal cohesion, as confirmed by energy framework calculations yielding a total interaction energy of −138.3 kJ mol−1. Hirshfeld surface analysis indicates that H...H interactions dominate, followed by C...H and O...H interactions, highlighting the role of van der Waals forces and hydrogen bonding in crystal packing.

structure Crystal structure of 1,10-phenanthrolinium violurate violuric acid pentahydrate By journals.iucr.org Published On :: 2024-11-14 The title compound [systematic name: 1,10-phenanthrolinium 6-hydroxy-5-(oxidoimino)-1,3-diazinane-2,4-dione–6-hydroxy-5-(hydroxyimino)-1,3-diazinane-2,4-dione–water (1/1/5)], C12H9N2+·C4H2N3O4−·C4H3N3O4·5H2O, is a co-crystal salt hydrate comprising 1,10-phenanthrolinium cations, violurate anions, free violuric acid as co-former and five water molecules of crystallization per formula unit. The violurate and the violuric acid residues each form distinct N—H...O hydrogen-bonded tapes with a common R22(8) hydrogen-bond motif extending parallel to (103). Solvent water molecules connect the tapes to form a tri-periodic hydrogen-bonded network with channels extending parallel to the a-axis direction, which accommodate the N—H...Owater hydrogen-bonded 1,10-phenanthrolinium cations. Direct N—H...O hydrogen bonds between the 1,10-phenanthrolinium and violurate ions are not encountered. Full Article text

structure Public School Grift Infrastructure Falters By www.mwilliams.info Published On :: Wed, 08 Dec 2021 11:42:22 -0600 I'm a big supporter of public education -- I went to public school and university for my entire education. Despite my libertarian leanings, I think taxpayer-funded, locally-directed public education can be a very valuable governmental function. However, I'm not a fan of the grift and graft that engulfs public education, for example the money laundering between teachers' unions and the Democrat party. I'm also not fond of the ideological indoctrination that many of the grifters seek to impose on American children, without the consent of the parents. So I think it's great that the "get woke, go broke" trend is finally hitting the public education grift infrastructure. Seventeen NSBA affiliates have cut ties with the NSBA over their coordination with the White House and Department of Justice in casting parental complaints over curricula "domestic terrorism." And as Axios reports, they're taking their checkbooks with them -- accounting for a 40% loss in revenue at the NSBA: The National School Boards Association has since apologized, but the fallout could be seven figures in annual funding. At least 17 state affiliates have severed ties with the group -- and some are even considering establishing a competitor. The 17 state affiliates accounted for more than 40% of annual dues paid to NSBA by its state association members in 2019, according to Axios' analysis of documents detailing those contributions. Officials fear upheaval at the organization -- the nation's leading trade group representing U.S. public schools -- will handicap it just as national debates over school curricula and COVID-19 mitigation measures dominate the political conversation.

structure Inverted tables: an alternative to relational structures By www.orafaq.com Published On :: Sun, 08 Sep 2013 08:52:30 +0000 articles: WarehousingThe inverted table format can deliver fast and flexible query capabilities, but is not widely used. ADABAS is probably the most successful implementation, but how often do you see that nowadays? Following is a description of how to implement inverted structures within a relational database. All code run on Oracle Database 12c, release 12.1.0.1. Consider this table and a few rows, that describe the contents of my larder: create table food(id number,capacity varchar2(10),container varchar2(10),item varchar2(10)); insert into food values(1,'large','bag','potatoes'); insert into food values(2,'small','box','carrots'); insert into food values(3,'medium','tin','peas'); insert into food values(4,'large','box','potatoes'); insert into food values(5,'small','tin','carrots'); insert into food values(6,'medium','bag','peas'); insert into food values(7,'large','tin','potatoes'); insert into food values(8,'small','bag','carrots'); insert into food values(9,'medium','box','peas'); The queries I run against the table might be "how many large boxes have I?" or "give me all the potatoes, I don't care about how they are packed". The idea is that I do not know in advance what columns I will be using in my predicate: it could be any combination. This is a common issue in a data warehouse. So how do I index the table to satisfy any possible query? Two obvious possibilities: First, build an index on each column, and the optimizer can perform an index_combine operation on whatever columns happen to be listed in the predicate. But that means indexing every column - and the table might have hundreds of columns. No way can I do that. Second, build a concatenated index across all the columns: in effect, use an IOT. That will give me range scan access if any of the predicated columns are in the leading edge of the index key followed by filtering on the rest of the predicate. Or if the predicate does not include the leading column(s), I can get skip scan access and filter. But this is pretty useless, too: there will be wildly divergent performance depending on the predicate. The answer is to invert the table: create table inverted(colname varchar2(10),colvalue varchar2(10),id number); insert into inverted select 'capacity',capacity,id from food; insert into inverted select 'container',container,id from food; insert into inverted select 'item',item,id from food; Now just one index on each table can satisfy all queries: create index food_i on food(id); create index inverted_i on inverted(colname,colvalue); To retrieve all the large boxes: orclz> set autotrace on explain orclz> select * from food where id in 2 (select id from inverted where colname='capacity' and colvalue='large' 3 intersect 4 select id from inverted where colname='container' and colvalue='box'); ID CAPACITY CONTAINER ITEM ---------- ---------- ---------- ---------- 4 large box potatoes Execution Plan ---------------------------------------------------------- Plan hash value: 1945359172 --------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | C --------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 3 | 141 | | 1 | MERGE JOIN | | 3 | 141 | | 2 | TABLE ACCESS BY INDEX ROWID | FOOD | 9 | 306 | | 3 | INDEX FULL SCAN | FOOD_I | 9 | | |* 4 | SORT JOIN | | 3 | 39 | | 5 | VIEW | VW_NSO_1 | 3 | 39 | | 6 | INTERSECTION | | | | | 7 | SORT UNIQUE | | 3 | 81 | | 8 | TABLE ACCESS BY INDEX ROWID BATCHED| INVERTED | 3 | 81 | |* 9 | INDEX RANGE SCAN | INVERTED_I | 3 | | | 10 | SORT UNIQUE | | 3 | 81 | | 11 | TABLE ACCESS BY INDEX ROWID BATCHED| INVERTED | 3 | 81 | |* 12 | INDEX RANGE SCAN | INVERTED_I | 3 | | --------------------------------------------------------------------------------- Predicate Information (identified by operation id): --------------------------------------------------- 4 - access("ID"="ID") filter("ID"="ID") 9 - access("COLNAME"='capacity' AND "COLVALUE"='large') 12 - access("COLNAME"='container' AND "COLVALUE"='box') Note ----- - dynamic statistics used: dynamic sampling (level=2) orclz> Or all the potatoes: orclz> select * from food where id in 2 (select id from inverted where colname='item' and colvalue='potatoes'); ID CAPACITY CONTAINER ITEM ---------- ---------- ---------- ---------- 1 large bag potatoes 4 large box potatoes 7 large tin potatoes Execution Plan ---------------------------------------------------------- Plan hash value: 762525239 --------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cos --------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 3 | 183 | | 1 | NESTED LOOPS | | | | | 2 | NESTED LOOPS | | 3 | 183 | | 3 | SORT UNIQUE | | 3 | 81 | | 4 | TABLE ACCESS BY INDEX ROWID BATCHED| INVERTED | 3 | 81 | |* 5 | INDEX RANGE SCAN | INVERTED_I | 3 | | |* 6 | INDEX RANGE SCAN | FOOD_I | 1 | | | 7 | TABLE ACCESS BY INDEX ROWID | FOOD | 1 | 34 | --------------------------------------------------------------------------------- Predicate Information (identified by operation id): --------------------------------------------------- 5 - access("COLNAME"='item' AND "COLVALUE"='potatoes') 6 - access("ID"="ID") Note ----- - dynamic statistics used: dynamic sampling (level=2) - this is an adaptive plan orclz> Of course, consideration needs to be given to handling more complex boolean expressions; maintaining the inversion is going to take resources; and a query generator has to construct the inversion code and re-write the queries. But In principle, this structure can deliver indexed access for unpredictable predicates of any number of any columns, with no separate filtering operation. Can you do that with a normalized star schema? I don't think so. I hope this little thought experiment has stimulated the little grey cells, and made the point that relational structures are not always optimal for all problems. -- John Watson Oracle Certified Master DBA http://skillbuilders.com Full Article
