Two new mesogenic monomers, namely 3,3’-dimethoxy-4,4’di(hydroxyhexoxy)-N-benzylidene-o-Tolidine (Ia) and 4,4’-di(6-hydroxyhexoxy)-Nbenzylidene-o-Tolidine (IIa), were reacted with cadmium sulfide (CdS) via an in situ chemical precipitation method in ethanol to produce CdS nanocomposites. A series of different mass compositions of CdS with Ia and IIa ranging from 0.1:1.0 to 1.0:1.0 (w/w) were pr...

throughout the present study, similar horizons (a, ab and b1) from deciduous forest, coniferous forest and rangeland types of land uses were selected, and the percentage of water stable aggregates in them measured. in each class of stable aggregate at the horizon a, free light fraction, free-particulate organic matter, intra-aggregate of particle organic mather (pom), and clay + silt complexes ...

Abstract The elongational rheology of blends a polystyrene (PS) Pom-Pom with two linear polystyrenes was recently reported by Hirschberg et al. (J. Rheol. 2023, 67:403–415). PS280k-2x22-22k self-entangled backbone ( M w,bb = 280 kg/mol) and 22 entangled sidearms w,a at each the branch points blended weight fractions from 75 to 2 wt% having w 43 kg/mol (PS43k) 90 (PS90k), respectively. While pur...

There are many effective chemothereutic agents used in influenza disease which some of them inhibit virus replication by interfering with FluV (influenza virus) viral binding or its penetration into cell membrane. A series of polyoxometalates compounds such as POM-523 and PM-504 have been synthesized and have showed inhibitory effects on viruses. In this study we examined anti influenza activit...

The phenolic Schiff bases I-VI were synthesized by condensation reactions between various diamines, namely o-dianisidine, o-tolidine and ethylenediamine with vanillin or p-hydroxybenzaldehyde and subsequent reactions between these phenolic Schiff bases and epichlorohydrin to produce new diglycidyl ethers Ia-VIa. The structures of these compounds were confirmed by CHN, FT-IR, (1)H-NMR, and (13)C...

Abstract A dramatically changing business landscape characterized by volatility and uncertainty (which in turn are driven unpredictable alterations of conditions such factors as geopolitical events, climate changes, disasters—natural human causes, reduction food, potable water, critical materials supply along with environmental contamination), has created a situation whereby rethink Production ...

in this note by considering a complete lattice l, we define thenotion of an l-fuzzy hyperrelation on a given non-empty set x. then wedefine the concepts of (pom)l-fuzzy graph, hypergraph and subhypergroupand obtain some related results. in particular we construct the categories ofthe above mentioned notions, and give a (full and faithful) functor form thecategory of (pom)l-fuzzy subhypergroups ...
