Thedevelopment, fecundity, and life tableparameters ofGonatocerus ashmeadiGirault, an egg parasitoid of the glassy-winged sharpshooter,Homalodisca coagulata (Say), were studied in the laboratory at six constant temperatures between 12 and 32 C. At 12 C, the parasitoid failed to develop beyond the third instar, and durations of the egg stage and the Þrst and second instarswere prolonged. Develop...

BACKGROUND/AIM Stimulation of the retina with flickering light increases retinal arterial and venous diameters in animals and humans, indicating a tight coupling between neural activity and blood flow. The aim of the present study was to investigate whether this response is altered in patients with insulin dependent diabetes mellitus. METHODS 26 patients with diabetes mellitus with no or mild...

Fifty-two Holstein bulls were castrated at 12, 16, 20, 24, 28 or 32 weeks to (1) determine whether testicular development is influenced by season of birth (April or October) and (2) examine quantitatively the establishment of spermatogenesis. Season of birth (spring or fall) did not influence (P less than .05) either testis weight at castration or the establishment of spermatogenesis. With age ...

The objective of the present study was to define the risk and the time required to develop frostnip on the face during exposure to cold winds. Twelve subjects (6 males and 6 females) were exposed to sixteen 45 min tests where the wind intensity varied between 0, 16 and 32 km/h. The tests were conducted at 0, -10, -20, -30, -40 and –50°C (only 0 km/h wind was present at -50°C). During the tests,...

The main task of paper studied new ciphering and deciphering techniques reported previously. Computer programs are designed in C language to perform theses algorithms and to assess their performance. Out of these algorithms, it is found that the BLOWFISH is the more sophisticated one. Therefore, a development for this algorithm is introduced to enhance its operation. This has been carried out b...

Visual prostheses based on micro-electronic technologies and biomedical engineering have been demonstrated to restore vision to blind individuals. It is necessary to determine the minimum requirements to achieve useful artificial vision for image recognition. To find the primary factors in common object and scene images recognition and optimize the recognition accuracy on low resolution images ...

OBJECTIVES To explore the urine bactericidal activity of co-amoxiclav and norfloxacin against Escherichia coli in an in vitro pharmacodynamic model simulating the human urinary concentrations observed after administration of a single oral dose of 2000/125 mg sustained-release co-amoxiclav and 400 mg norfloxacin. METHODS Six E. coli isolates exhibiting amoxicillin/clavulanic acid MICs of 4/2 (...

Chromosome numbers and 2C-values of six Byblis species were determined to investigate the chromosome differentiation genome diversity in this genus. Somatic B. liniflora complex showed diploid tetraploid 2n=16 32. In contrast, number gigantea, which belongs gigantea complex, displayed only 2n=36. The 2C DNA contents across all studied over a three-fold range, from lowest value 2C=0.64 pg rorida...
