NITROGEN, PHOSPHORUS, AND POTASSIUM RANGE OF VERMICOMPOST USING EISENIA FETIDA AND PERIONYX EXCAVATUS
The aim of the presentation is to produce vermicomposting from organic kitchen solid wastes using two types of earthworms such as Eisenia fetida and Perionyx excavatus and check the nitrogen, phosphorus, and potassium level between E. fetida and P. excavatus. This study examines the potential of the E. fetida and P. excavatus in the vermicompost of kitchen waste. As kitchen waste is rich in organic material. Physical and biochemical parameters were analyzed during the period of 60 days. Pre-decomposition is 15 days and subsequent vermicomposting is 60 days indicates, the rule of these species of vermitechnology increase was found in all the parameters such as total nitrogen (%), available phosphorus (%), and exchangeable potassium (%) while a decrease was found in pH and carbon-to-nitrogen ratio in E. fetida as the timing of vermicomposting increased from 0 days to 60 days
Vilsmeier—Haack Reaction on Quinaldines.
2069-2073The study of the Vilsmeier-Haack reaction
on 4-hydroxyquinaldines resulted with the preparation of rarely existing
4-chloro-3-formyl-2(vinyl-1-ol)-quinolines
Synthesis and antibacterial activity of pyrimido[4,5<i>-b</i>]quinolines
688-689A concise one-pot synthesis of pyrimido[4,5-b]quinolines
3a-e has been achieved from the potential substrates 2-chloro-3-formylquinolines
1 and guanidine nitrate 2. All the synthesized compounds have been
biologically screened for their antibacterial activity
Synthesis and antibacterial activities of newer derivatives of pyrido[2,3-<i>d</i>; 6,5-<i>d</i>'] dipyrimidines
1734-1737An elegant one-pot synthesis of the title
compounds 3a-f has been reported in good yields. Treatment of 1,3-diaryl-2-thiobarbituric
acid with pyrrole-2-carbaldehyde and liquor ,ammonia in anhydrous ethanol for about
4hr affords the requisite 1,2,3,4,6,7 ,8,9-octahydro-l ,3,7,9-tetraphenyl-5-(2-pyrrolyl)-4,6-dioxo-2,8-dithio-10H,5H-pyrido[2
,3-d;6,5-d'] dipyrimidines. All the synthesized compounds have
also been screened for the antibacterial activities against Salmonella
typhii and Aeromonas hydrophila.</i

Synthesis, characterization and antimicrobial activities of fused 1,6-naphthyridines
2375-2379An
easy two-step synthesis of 1,6-naphthyridines (4a-c, 7a-c, 10a-c, 14a-c) has been arrived from
3-formylquinolin-2(1H)-ones 1a-c and respective arylamines (2,
5, 8, 12) which underwent condensation and aromatized by dehydration with
the help of PPA. All the synthesized compounds have been biologically screened
for their antibacterial and antifungal activities
Synthesis, characterization and antimicrobial activity of 4-phenyl-3-thiopyrimido[4,5<i>b</i>] quinolines
2133-2135An easy one-step synthesis of substituted
pyrimido[4,5-b]quinolines 3a-e has been achieved from
2-chloro-3-formyl quinolines 1 and N-Phenyl thiourea 2.
All the synthesized compounds have been biologically screened for their
antibacterial and antifungal activities
A novel approach to 12-chloro-3-thio-4H-quino [3,2-e][1,3]diazocines via Vilsmeier Haack reaction
995-1000The Vilsmeier Haack reaction on 4-hydroxyquinaldines lead to potential intermediate 4-chloro-3-formyl-2-(2-hydroxy-ethene-1-yl) quinolines. The intermediate is further utilized to prepare quino[3,2-e][1,3]diazocines on treatment with thiourea. The structures of the new compounds are determined by the analytical and spectroscopic data
