To study the effect of some fungicides invitro on an isolate of the fungus Cladosporium fulvum(cook) that causes leaf mold on tomatoes, five fungicides were tested Flint - Topsin-M- Score and Collisand Indofil-M at concentrations between 1 - 4000 p
pm. The results showed that Score and Indofil-M were the most effective fungicides inhibiting hyphal growth for the isolate even at 10ppm. Also, they inhibited completely the spores germinatios at the 100 ppm. The effects of fungicides Flint and Collis were weak on hyphal growth of the isolate and inhibited almost completely the spores germinatios at 1000 ppm. We didn,t observe clear inhibiting effects of Topsin-M on hyphal on the growth of the spores germinatios at 1000 ppm .
Background& Objective: Onychomycosis is a frequent nail disease caused by dermatophytes, yeasts, and
non-dermatophyte molds. Far more than being a simple cosmetic problem, infected nail serves as a
chronic reservoir, which can give rise to repeated
mycotic infections.
This study aim to identify the common fungal species which are responsible for onychomycosis in
clinically suspected patients of onychomycosis in Dermatology and Venereal Diseases Hospital in
Damascus between October 2010 and July 2011.
Materials & Methods: Both direct microscopy and culture of the nail material were performed to identify
the causative fungi of onychomycosis.
Results: Culture positivity was obtained in 65 of the 76 clinically suspected samples, etiological fungal
agents were (%61.5) dermatophytes, (24.6%) yeasts, and (13.9 %) non-dermatophyte molds . The isolated
fungal species were (43.1%) Trichophyton Rubrum and (16.9%) T. Interdigitale (1.5%) T.Verrucosum
Aspergillus Versicolor which was the most frequent non dermatophyte molds. Females were affected in
fingernails more frequently than males, while males were affected in toenails more frequently than
females, and in both sexes those most infected were between 20-40 years of age.
Conclusion: Dermatophytes, in particular T. rubrum, but also T. Interdigitale, are the most frequently
isolated causative agents in onychomycosis in patients seen in Dermatology and Venereal Diseases
Hospital in Damascus . In addition, yeasts may be isolated relatively frequently, while molds are
uncommon.
We have done many counts, strength and twist tests - which are considered the most important physical properties that determine yarns quality specification - on cotton yarns at the industrial researches& tests center. The researcher has depended on t
his tests results to find out formulas which match between physical properties of yarns, starting from common formulas then he has proved them by analysis of results that we got from graphic tests instruments, then we have figured out proportion constants between these physical properties from curves that we have got by tests results exemplification and we have shown if these constants describe common constants or new constants.
Ring, Rotor(O.E) and Air vortex spinning systems provide yarns with different structures and
properties. Each system has its limitations and advantages in terms of technical feasibility and economic
viabilit y Ne 30, 100%cotton yarns were produced
from the above systems and knitted in single jersey
machine .The Rotor Spun yarns found with frequent breakage during knitting.
