mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. carbomers are among the best mucosa-adhesive materials known. the aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing carbomers, either alone or in combination, to the data obtained from assessing the d...

the partition coefficients (p-values) of certain new potential, stereoselective, reversible, long-acting local anesthetics have been determined in an n-octanol/ phosphate buffer system. these are derivatives of 2-phenoxyethyldialkylamine hydrochloride, and almost all of them are readily soluble in water. their aqueous solutions have shown different absorption maxima, and these have been used qu...

Abstract: This paper presents an exact model and a genetic algorithm for the multi-mode resource constrained project scheduling problem with generalized precedence relations in which the duration of an activity is determined by the mode selection and the duration reduction (crashing) applied within the selected mode. All resources considered are renewable. The objective is to determine a mode, ...

The thermal requirements for development of Dermanyssus gallinae were studied under laboratory conditions at 15, 20, 25, 30 and 35 degrees C, a 12h photoperiod and 60-85% RH. The thermal requirements for D. gallinae were as follows. Preoviposition: base temperature 3.4 degrees C, thermal constant (k) 562.85 degree-hours, determination coefficient (R(2)) 0.59, regression equation: Y= -0.006035 +...

oriental hybrid lily “arabian red” mother scales were stored in moist cocopeat and perlite (1:1) for 3 or 5 months at 25 ̊c. the numbers of scale bulblets per mother scale were nearly identical in two durations. increasing storage duration promoted the growth of roots (number and length) and no. scales per scale bulblets. and, diameters of scale bulblets were more in longer storage duration (5 m...

objective: to identify the proportion and some selected characteristics of juvenile diabetics attending birdem hospital. materials and methods: this was a cross sectional study. the study was conducted in the birdem hospital. all diabetic young aged up to 18 years who visit birdem hospital were included in study population. the sample size was 240. results: it was observed that among the respon...

The ability of predatory mites to endure starvation or low humidity is very important for them to maintain their populations in unfavorable environments. The effects of starvation and humidity on the development and survival of Amblyseius (Typhlodromips) swirskii, Amblyseius eharai and Agistemus exsertus were studied in the laboratory. The results showed that most eggs of A. eharai and A. exser...
