For the closed relativistic string carrying a pointlike mass the exact solutions of the dynamical equations are obtained and studied. These solutions describe states of the mentioned system moving in Minkowski space and also in the space that is the direct product of Minkowski space and a compact manifold (torus). We consider the closed relativistic string with one massive point (homeomorphic t...

Present experiments were conducted to determine the possibility of artificial culture with various sawdust of P. gilvus. The pH value was 6.0 of oak sawdust, 6.5 of mulberry sawdust, 6.6 of elm sawdust, 6.3 of acacia sawdust and 6.1 of apple tree sawdust. Mycelial density on elm sawdust and acacia sawdust were lower than those of oak sawdust, and apple sawdust. Weight of fresh fruiting body sho...

Three closely related oRUulosic q l i c latex 6ims were prepared employing acacia pulp fibers, cellulose whiskers and daclocellulose balls and their respective strength properties were determined. Wulose whisker reinforced composites had &md stl.ength properties compGired to the acacia pulp and nanoball composites. APM analysis indicated that the d u b w h i s h &or& composite exhibited d e c r...

By applying a fed-batch strategy, production of Penicillium occitanis mannanases could be almost doubled as compared to a batch cultivation on acacia seeds (76 versus 41 U/mL). Also, a 10-fold increase of enzyme activities was observed from shake flask fermentation to the fed-batch fermentation. These production levels were 3-fold higher than those obtained on coconut meal. The high mannanase p...

Obligate Acacia ant plants house mutualistic ants as a defense mechanism and provide them with extrafloral nectar (EFN). Ant/plant mutualisms are widespread, but little is known about the biochemical basis of their species specificity. Despite its importance in these and other plant/animal interactions, little attention has been paid to the control of the chemical composition of nectar. We foun...

The polysaccharide exuded by Acacia decurrens trees contains residues of D-galactose , LArabinose , L-Fucose and Dglucuronic acid. An examination of the OMethyl derivatives of the gum yields 2,3,4,6 tetra –O-methyl –D-galactose, 2,3 –di-O-Methyl –L-arabinose , 2,3,4-triO-methyl-D-galactose, 2,4-di-O-methyl-D-galactose together with 2,3,4 tri-O-methyl-Dglucuronic acid by acid hydrolysis. The deg...

Synbiotics offer potential in the prophylactic management of gastrointestinal disorders. Therefore, present study evaluates the effect of prebiotics (inulin and gum acacia) on Lactocaillus plantarum for developing a freeze-dried synbiotic product from the selected culture. L. plantarum exhibited the highest specific growth rate (0.23/h) in presence of inulin followed by gum acacia (0.22/h) and ...

BACKGROUND The aim of the present study was to evaluate the physicochemical and antioxidant properties of Malaysian monofloral honey samples-acacia, pineapple and borneo honey-and compare them with tualang honey. Acacia and pineapple honey are produced by Apis mellifera bees while borneo and tualang honey are produced by Apis cerana and Apis dorsata bees, respectively. METHODS The physical pa...

Determining how competing species coexist is essential to understanding patterns of biodiversity. Indirect facilitation, in which a competitively dominant species exerts a positive effect on one competitor by more strongly suppressing a third, shared competitor, is a potentially potent yet understudied mechanism for competitive coexistence. Here we provide evidence for indirect facilitation in ...

Ritonavir, a widely prescribed anti-retroviral drug, belongs to Class II under 'BCS' and exhibit low and variable oral bioavailability due to its poor aqueous solubility. Ritonavir is practically insoluble in water and aqueous fluids. Its aqueous solubility was reported to be 2.56 mg/100 ml. As such oral absorption of ritonavir is dissolution rate limited and it requires enhancement in solubili...
