Opis:
A library of quinoline analog two novel series of azetidin (SH1-5) and thiazolidin (SHa-e) derivatives were designed and synthesized with simple and eco-friendly methodologies. The structures of the compounds were elucidated with the aid of elemental analysis, IR, 1H-NMR and mass spectral data. These novel synthesized compounds were evaluated for antibacterial activity against two gram-positive bacteria (Staphylococcus aureus, Staphylococcus pyogenus) and two gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli). The title compounds were also studied for their antifungal activity with Candida albicans, Aspergillus niger, Aspergillus clavatus using the broth dilution technique. Most of the compounds were the best bio-active desired antibacterial analog with less MIC value against different tested strains.

Opis:
In this paper, an inventory system is analyzed regarding a trended demand. The seller offers its buyer a credit period for settling the account, which attracts more buyers and enhances market demand. However, the offer of credit period leads to default risk for the supplier. The units in inventory are deteriorating continuously and also have definite maximum lifetime. The aim is to maximize the profit of the retailer. Numerical examples are given to validate the developed mathematical model. Sensitivity analysis is performed to obtain the critical inventory parameters and deduce the managerial strategies.

Opis:
Montmorillonite filled and unfilled controls, jute/treated jute/glass/hybrid composites were prepared at room temperature for three h and under 5 MPa pressure. The composites were post cured at 150 °C for 30 min. A 40% styrene was used as a reactive diluent, and 1% methylethylketone peroxide, 1.5 % cobalt octoate, and 1.5% dimethylaniline were used as initiator and accelerator, and a promoter. Filled and unfilled composites showed good to excellent mechanical and electrical properties, excellent hydrolytic stability and chemical resistance against water acids, alkali, salt solutions; high water absorption tendency (7.9-20.5%), and longer equilibrium times (288-432h). In different environments at 30 °C observed water absorption trend is H2SO4 > HCl > NaOH > H2O > NaCl. Hybrid composites showed intermediate properties of their parent composites. MMT filled treated jute (46), and unfilled glass (48), and MMT filled glass (48) composites revealed Barcol hardness between the suggested range of 45-65 for scratch and wear resistance proof materials. The nature of the reinforcements, matrix, and filler; fiber treatment, environmental conditions, etc., had affected studied properties and water absorption behavior.
